Globalization and European Integration have initiated some debate on this understanding, but cross-cross-border cooperation has rarely been linked to this debate. In these areas enormous political changes have been seen during the recent years. Still, the territorial dimension cannot be addressed, as territoriality as known from nation states is challenging politics. However, the territorial implications are manifold and are increasing throughout Europe. Against this backdrop is conceptual reflection. This paper starts with a brief overview of discussions and the empirical implementation of the territoriality debate. Based on this, the paper attempts to catch up with the political changes – the reflection of cross-border territorialities in a two-fold way. The purpose of this paper is to contribute to this field. First, we propose a methodological approach to study the essential aspects. We study from a conceptual point of view, the dimensions of territoriality in cross-border contexts. These are explored as well as the political-juridical background of cross-border cooperation. Based on this, a C-B-IM-tool (Cross-Border Institutional Mapping) has been introduced, involving three steps: (a) (a1) multi-level mapping of cross-border institutions, (b) (a2) mapping of policy arenas and (c) (a3) mapping of the political topography in the sense of going beyond formalized and codified governance patterns. Secondly, with the example of the Greater Region around Luxembourg, the empirical and conceptual findings on cross-border territoriality are illustrated. We can state an establishing cross-border territoriality that does not replace domestic, state-centric territorialities but that inserts new and complex elements of a multi-level territoriality system. urn:issn:0965-4313 European Planning Studies, 20 (6), 961-980 (2012)

Bioinformatics annotation methods combined with GCxGC/MS-based metabolomics and LC/MS-based shotgun proteomics profiling technologies have been applied to characterize abundant proteins and metabolites, resulting in the detection of 1069 proteins and 159 metabolites. Of the measured proteins, 204 currently do not have EST sequence support; thus a significant portion of the proteomics-detected proteins provide evidence for the validity of in silico gene models. Furthermore, the generated peptide data lend support to the validity of a number of proteins currently in the proposed model stage. By integrating genomic annotation information with experimentally identified metabolites and proteins, we constructed a draft metabolic network for Chlamydomonas. Computational metabolic modeling allowed an identification of missing enzymatic links. Some experimentally detected metabolites are not producible by the currently known and annotated enzyme set, thus suggesting entry points for further targeted gene discovery or biochemical pathway research. All data sets are made available as supplementary material as well as web-accessible databases and within the functional context via the Chlamydomonas-adapted MapMan annotation platform. Information of identified peptides is also available directly via the JGI-Chlamydomonas genomic resource database (http://genome.jgi-psf.org/Chlre3/Chlre3.home.html). urn:issn:0016-6731 Genetics, 179 (1), 157-66 (2008)

The attitudes of medical students towards their later work in the health system is important for current health care planning. For that reason a nationwide survey aimed to identify major trends in preferred specialty, workplace characteristics (regional location, hospital) and perceived hindrances for clinical work. Methods: A questionnaire consisting of 34 closed questions was developed at the University of Mainz in 2009 and administered over the Internet in June and July 2010 to all medical students in Germany. The questions addressed the students’ intentions regarding specialty training, location of practice, workload, and regional preference, as well as potential reasons why they might choose not to practice clinical medicine in the future. Results: 12 518 web-based questionnaires were filled in (approx. 15.7% of all medical students in Germany in 2010). The mean age was 24.9 years, with 64% female and 36% male. Favored specialties were internal medicine (42.6%), family medicine (29.6%), pediatrics (27.0%) and surgery (26.8%). Nearly all respondents (96%) stated that they attached importance to compatibility of work and family life. Working in a salaried position (92.2%) was preferred to working in private practice (77.7%). General practice, in particular in rural locations, was significantly less favored than work as a specialist in cities. Conclusion: Although the coming generation of physicians anticipate working in clincial settings in the future, shortfalls in the areas of primary care and in rural locations are likely if medical students adhere to their preferences stated in the questionnaire. urn:issn:1866-0452 Deutsches Ärzteblatt International, 109 (18), 327-332 (2012)

The cooperative behavior of an ensemble of such rods and bundles thereof exhibits self-organized pattern formation on different length scales. Pattern formation on large length scales reveals great similarity with physical systems undergoing spinodal decomposition. Possible applications for dipolar magnetic nanorods in the field of perpendicular storage media are highlighted. We discuss an aerosol-synthesis-route allowing to prepare ferrofluids (FF) with shape-anisotropic particles constituting the magnetic phase immersed in the nonmagnetic carrier fluid. These so-called nanorod FF unveil a two orders of magnitude increase of viscosity enforced by an applied field of 10mT even at shear rates larger than 10-2s.

In a recently developed technique, time-resolved polarized SANS tries to make use of spatial polarization gradients created around paramagnetic centres at the onset of dynamic nuclear polarization. The time constants which describe the build-up of polarization around the paramagnetic centre and the subsequent diffusion of polarization in the solvent were determined by analysing the temporal evolution of the nuclear polarization. The possible use and the limitations of this technique as a spectroscopic tool are discussed. urn:issn:0021-8898 Journal of Applied Crystallography, 40 (s), 106 - 110 (2007)

They are intended to be used as regularized coordinates to which some corrections should be added to access instantaneous coordinates. The latest ITRS realization is the ITRF2005, which has integrated time series of station positions to form long-term solutions for the four space geodetic techniques. Currently, a purely linear model is used to parameterize station displacements in the estimation process, plus occasional discontinuities in case of earthquakes or equipment changes. However the input data have been derived without applying surface loading models and so surface loading effects are supposed to be embedded in the coordinates as measured quantities. We evaluate the effect of applying a posteriori loading corrections, which include the effect of atmospheric, non-tidal ocean, and continental water loading, to time series of positions estimated from Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI), and Global Positioning System (GPS) data. We notice that they reduce about 50% or more of the annual signals in the translation and scale parameter time series of the SLR and VLBI techniques, except in SLR Z translation. In general, the estimated secular frame definition is negligibly affected and estimated positions and velocities are not significantly modified for stations that have accumulated a large number of observations. A multi-technique combination of such derived frames allows concluding that, for some cases, loading model corrections might degrade co-located station coordinates almost as much as they benefit them. However, most significant improvement of the estimated secular coordinates is observed for stations with less than 100 estimated positions as demonstrated with a multi-technique combination. urn:issn:0273-1177 Advances in Space Research, 45 (1), 144-154 (2010)

This is a report on the long-range magnetic order and the magnetic excitations in a nanocrystalline elemental rare earth. Refinement of the neutron-diffraction data reveals an “average” magnetic structure of each crystallite which contains a significant out-of-plane component to the magnetic moment as well as a suppression of the high-temperature antiferromagnetic phase observed for coarse-grained Tb. The inelastic-neutron-scattering measurements reveal the presence of a magnetic excitation of approximately 10 meV at 2.5 K. The excitation energy decreases with increasing temperature. The origins of this excitation are discussed with particular reference to the magnetic modes at the zone center observed for single-crystal Tb. urn:issn:0021-8979 Journal of Applied Physics, 99 (8), 5021-5023 (2006)

In the limit of high applied magnetic field H, for which the scattering volume is a single magnetic domain and the magnetization is nearly aligned with the direction of the applied field, a combination of micromagnetics theory with neutron scattering formalism suggests closed-form expressions for the differential scattering cross section as a function of the scattering vector and of H. Based on these results it is suggested that the exchange-stiffness constant can be extracted from experimental SANS data recorded as a function of H. At ambient temperature we have applied this method to polycrystalline cold-worked Ni and nanocrystalline electrodeposited Ni, finding exchange-stiffness constants of (8.2±0.2)×10−12 and (7.6±0.3)×10−12 J/m, respectively. Measurement at 5 K yields a value of (9.2±0.2)×10−12 J/m for the nanocrystalline sample, a temperature dependence that agrees qualitatively with data in the literature. In addition to the value of A, the technique supplies information on the spatial structure of the magnetic anisotropy field. urn:issn:0021-8979 Journal of Applied Physics, 87 (9), 5953 - 5955 (2000)

In the EHBA-CrV complex, the spins of the 20 protons which surround the paramagnetic CrV can be oriented using the method of dynamic nuclear polarisation (DNP), thereby offering the possibility to create locally a nuclear spin-dependent contrast for SANS. The time constants which describe the build-up of polarisation around the paramagnetic centre and the subsequent diffusion of polarisation in the solvent were determined by analysing the temporal evolution of the nuclear polarisation, which in turn was obtained by fitting a core-shell model to the time-dependent SANS curves. The results on the spin dynamics obtained using the scattering function of a core-shell could be independently confirmed by evaluating the integrated SANS intensity. A thermodynamic one-centre model is presented which is able to reproduce the observed dependence of the proton polarisation times on the proton concentration of the solvent. urn:issn:1434-6028 European Physical Journal B -- Condensed Matter, 49 (2), 157-165 (2006)

Physical, chemical, mathematical & earth Sciences Physics Physique, chimie, mathématiques & sciences de la terre Physique This paper presents a calculation of the magnetic small-angle neutron scattering cross-section resulting from a dilute ensemble of superparamagnetic particles exhibiting uniaxial magnetic anisotropy. We focus on the two experimentally relevant scattering geometries in which the incident neutron beam is perpendicular or parallel to an applied magnetic field, and we discuss several orientations of the anisotropy axes with respect to the field. Magnetic anisotropy has no influence on the magnetic small-angle neutron scattering when the particles are mobile, as is the case e.g. in ferrofluids, but, when the particles are embedded in a rigid non-magnetic matrix and the orientations of the anisotropy axes are fixed, significant deviations compared to the case of negligible anisotropy are expected. For the particluar situation in which the anisotropy axes are parallel to the applied field, closed-form expressions suggest that an effective anisotropy energy or anisotropy-energy distribution can be determined from experimental scattering data. urn:issn:1434-6028 European Physical Journal B -- Condensed Matter, 26, 57-65 (2002)

This paper presents the analysis of a mathematical model for carbohydrate uptake and metabolism in Escherichia coli. It is shown that the dynamic processes cover a broad time span from some milliseconds to several hours. Based on this analysis the fast processes could be described with steady-state characteristic curves. A subsequent robustness analysis of the model parameters shows that the fast part of the system may act as a filter for the slow part of the system; the sensitivities of the fast system are conserved. From these findings it is concluded that the slow part of the system shows some robustness against changes in parameters of the fast subsystem, i.e. if a parameter shows no sensitivity for the fast part of the system, it will also show no sensitivity for the slow part of the system. urn:issn:0303-2647 Bio Systems, 73 (1), 57-71 (2004)

Mathematical models describing these processes might be of great help to gain qualitative and, most importantly, quantitative knowledge about such complex systems. However, a detailed mathematical description of these systems leads to nearly unmanageably large models, especially when combining models of different signalling pathways to study cross-talk phenomena. Therefore, simplification of models becomes very important. Different methods are available for model reduction of biological models. Importantly, most of the common model reduction methods cannot be applied to cellular signal transduction pathways.

We compare solution sets that differ only in the frame used for the OTL model computations, for three types of GPS solutions. In global solutions with all parameters including orbits estimated simultaneously, we find coordinate differences of ∼0.3mm between solutions using OTL computed in CM and OTL computed in CE. When orbits or orbits and clocks are fixed, larger biases appear if the user applies an OTL model inconsistent with that used to derive the orbit and clock products. Network solutions (orbits fixed, satellite clocks estimated) show differences smaller than 0.5 mm due to model inconsistency, but PPP solutions show distortions at the ∼1.3 mm level. The much larger effect on PPP solutions indicates that satellite clock estimates are sensitive to the OTL model applied. The time series of coordinate differences shows a strong spectral peak at a period of ∼14 days when inconsistent OTL models are applied and smaller peaks at ∼annual and ∼semi-annual periods, for both ambiguity-free and ambiguity-fixed solutions. These spurious coordinate variations disappear in solutions using consistent OTL mod- els. Users of orbit and clock products must ensure that they use OTL coefficients computed in the same reference frame as the OTL coefficients used by the analysis centers that produced the products they use; otherwise, systematic errors will be introduced into position solutions. All modern products should use loading models computed in the CM frame, but legacy products may require loading models computed in the CE frame. Analysts and authors need to document the frame used for all loading computations in product descriptions and papers. urn:issn:0949-7714 Journal of Geodesy, 1-3 (2011)

The GPS and SLR annual signals agree but are different (16%) to the load model.

The area is well suited to test the application of an observational strategy which combines different techniques to extract information on the spatial and temporal variability of the subsidence. The simultaneous availability, at a few stations, of several geodetic observation techniques such as Global Positioning System (GPS), gravity, and Interferometric Synthetic Aperture Radar (InSAR) allows for validation of the individual time series. The combination takes advantage of the complementary strengths of each technique by overcoming the limitations inherent in each single technique alone. The combination of velocities derived from the GPS and gravity data, further complemented by the results of the InSAR Permanent Scatterers technique, allows us to monitor continuously, in space and time, vertical crustal movements. This high-density information is of major importance for understanding the processes responsible for the observed deformation. Here long-term trends were derived, enabling us to map the behavior of subsidence (even exceeding 20 mm/yr) with high spatial resolution in the southeastern Po Plain. The uplifting behavior of the Apennines chain bordering the Po Plain is identified together with a narrow zone separating the contrasting vertical crustal movements.

Observed tidal parameters, corrected for ocean loading effects, are compared with theoretical tidal parameters predicted for a non-hydrostatic inelastic Earth model and demonstrate excellent agreement. Tidal residuals, corrected for polar motion and a linear instrument drift are highly correlated with gravity changes measured by two absolute gravimeters over the same time period. The admittance to local pressure i s found to be -0.356 mGal/mbar. However, this admittance factor is found to be seasonally and frequency dependent. Correlations between rainfall events and gravity changes are observed. Attempts to model these gravity changes as exponential functions of time were unsuccessful. urn:issn:0094-8276 urn:issn:0094-8276 Geophysical Research Letters, 25 (3), 393-396 (1998)

We concentrate on 4 sites in a region of North America experiencing postglacial rebound. The rates of uplift from gravity and GPS agree within one standard deviation for all sites. The GPS vertical deformation rates are signi cantly more precise than the gravity rates, primarily because of the denser temporal spacing provided by continuous GPS tracking. We conclude that continuous GPS observations are more cost e cient and provide more precise estimates of vertical deformation rates than campaign style gravity observations where systematic errors are di cult to quantify. urn:issn:0094-8276 urn:issn:0094-8276 Geophysical Research Letters, 27 (23), 3925-3928 (2000)

A validation of the ECCO model is performed by comparing model estimates of sea-level anomalies from tide-gauges with TOPEX/ POSEIDON data, and ECCO model estimates of bottom pressure with those derived from temperature and salinity observations. The amplitudes of theECCO sea-level anomaly are found to be 1.4 times smaller than observations; bottom pressure is 2 times smaller. Using a Green’s functions approach to determine elastic deformations, the ECCO ocean bottom pressure is used to estimate surface displacements at the GPS sites. Model results were compared with the height series and with the observed NTOL effect. The height series and the predicted NTOL are highly correlated at all four stations. The analysis performed on superconducting gravimeter data at the Medicina station also shows high correlation. urn:issn:0094-8276 urn:issn:0094-8276 Geophysical Research Letters, 31 (L23609), 1-5 (2004)

The about 20 different phosphotransferase systems (PTSs) of the cell fulfill besides the transport of various carbohydrates, also the function of one signal processing system. Extra- and intracellular signals are converted within the PTS protein chain to important regulatory signals affecting, e.g. carbon metabolism and chemotaxis. A detailed dynamical model of the sucrose PTS was developed describing transport and signal processing function. It was formulated using a detailed description of complex formation and phosphate transfer between the chain proteins. Model parameters were taken from literature or were identified with own experiments. Simulation studies together with experimental hints showed that the dynamic behavior of phosphate transfer in the PTS runs within 1 s. Therefore a description of steady state characteristics is sufficient for describing the signaling properties of the sucrose PTS. A steady state characteristic field describes the degree of phosphorylation of the PTS protein EIIACrr as a function of the input variables extracellular sucrose concentration and intracellular phosphoenolpyruvate (PEP):pyruvate ratio. The model has been validated with different experiments performed in a CSTR using a sucrose positive E. coli W3110 derivative. A method for determining intracellular metabolite concentrations has been developed. A sample preparation technique using a boiling ethanol buffer solution was successfully applied. The PTS output signal degree of phosphorylation of EIIACrr was also measured. Steady state conditions with varying dilution rate and dissolved oxygen concentration and dynamical variations applying different stimuli to the culture were considered. Pulse, and stop feeding experiments with limiting sucrose concentrations were performed. Simulation and experimental results matched well. The same holds for the expanded sucrose PTS and glycolysis model. urn:issn:0168-1656 Journal of Biotechnology, 110 (2), 181-99 (2004)

The case encompasses the complex relationships between a child (who triggers the crisis), the child’s parents and the childcare centre as an organisation under change. First, some pertinent organisation-sociological references (change; “loose coupling”) are worked up theoretically, discussed in the light of ethnographies of pedagogical organisations, and criticised with respect to applications in pedagogical fields (organisation development). These discussions lead to tentative outlines of an organisational ethnographic methodology. The following processual presentation of the organisational ethnographic case study yields, finally, the basis for some analytic abstractions which elaborate organisation-sociological theorems with regard to early childcare institutions and connect them with questions of the sociology of childhood. Thereby, both the organisation’s adaptive performances, which are integrated into the everyday life by way of institutional practices, and the constitutive contribution of the children to the success (or failure, respectively) of the organisation become apparent. Der Beitrag rekonstruiert die initiale Institutionalisierung einer Luxemburger Maison Relais pour Enfants am Fall einer Krisenbewältigung als organisationalem Lernprozess. Der Fall setzt sich aus den komplexen Beziehungen zwischen einem Kind (welches die Krise auslöst), den Eltern des Kindes und der frühpädagogischen Einrichtung als sich verändernder Organisation zusammen. Zunächst werden organisationssoziologische Bezüge (Wandel; „lose Kopplung“) theoretisch aufbereitet, im Lichte von Ethnografien pädagogischer Organisationen diskutiert und mit Blick auf Anwendungen in pädagogischen Feldern (Organisationsentwicklung) kritisiert. Aus diesen Diskussionen werden Konturen einer organisationsethnografischen Methodologie entwickelt. Die anschließende prozessuale Darstellung der organisationsethnografischen Fallstudie liefert die Grundlage für zum Schluss folgende analytische Abstraktionen, welche organisationssoziologische Theoreme für frühpädagogische Einrichtungen differenzieren und an kindheitssoziologische Fragen anbinden. Dabei werden sowohl die über institutionelle Praktiken in den Alltag selbst integrierten Anpassungsleistungen der pädagogischen Organisation, als auch der konstitutive Beitrag der Kinder zum Gelingen (bzw. auch Misslingen) des organisationalen Alltags augenscheinlich. urn:issn:1436-1957 urn:issn:0720-4361 Zeitschrift für Soziologie der Erziehung und Sozialisation = Journal for Sociology of Education and Socialization, 33 (1), 42-61 (2013)

Most of the uplift results from ice dynamic-induced volume losses on two nearby outlet glaciers. Volume loss from Helheim Glacier, calculated from sequential digital elevation models, contributes about ~16 mm of the observed uplift, with an additional ~5 mm from volume loss of Kangerdlugssuaq Glacier.

The present study thus aimed at investigating which combinations of humor styles exist and to which extent these humor types are associated with well-being. In an online questionnaire, the Humor Styles Questionnaire (HSQ, Martin et al. J Res Pers 37:48–75, 2003), self-regulatory strategies, self-esteem, and well-being instruments were administered to a German sample. Exploratory and confirmatory factor analyses replicated the underlying structure of the HSQ. With hierarchical clustering, we found evidence for three humor types (endorsers, humor deniers, and self-enhancers), which differed in group means for self-esteem, self-regulatory strategies, and well-being. Findings provide further evidence for the positive well-being correlates of self-enhancing humor, and distinctly address the positive correlates of aggressive and self-defeating humor being absent. It is discussed that humor styles cannot be conceptualized as beneficial or detrimental per se, but have to be regarded in context. urn:issn:1389-4978 Journal of Happiness Studies, 14 (2), 551-569 (2013-04)

However, it has not yet been demonstrated whether these surface displacements should be accounted for at the time of reduction of the observations or by applying time-averaged values to the coordinates after the analysis of the observations. An analysis of the power spectral density of the ATML predicted vertical deformation shows that, aside from the diurnal and semi-diurnal periods, there is very little power in the sub-daily frequencies. The present tidal ATML models improve the analysis at sites near the equator but seem to degrade the height estimates elsewhere. The majority of the non-tidal deformation can be modelled by applying a daily-averaged correction to daily estimates of coordinates but a greater improvement in height RMS is found if non-tidal ATML is applied at the observation level. urn:issn:0094-8276 urn:issn:0094-8276 Geophysical Research Letters, 32 (L22310), 1-4 (2005)

Middle-aged adult offspring (N = 709) rated how often they and a sibling received parental recognition, nurturance, and demands for assuming filial responsibility. In addition, they indicated their justice evaluations of PDT and completed measures of relationship quality to sibling and parents. Justice evaluations emerged as either partial or complete mediators between PDT and relationship quality. Moreover, justice evaluations turned out to be more powerful predictors of relationship quality to parents than PDT per se. Implications are discussed concerning factors contributing to justice evaluations and the role of PDT within the context of other justice issues in families.

The aim of this study was to test, in the context of a very favorable labor market, (1) the detrimental effect of unemployment on mental health and (2) the predictive validity of mental health on further employment status. The population of the study comprised 384 newly registered unemployed persons. Mental health was assessed through four variables: self-esteem, psychological distress, perceived stress, and depressive symptoms. The results did not confirm previous studies. Using analyses of variance for repeated measures and linear regression, a negative change of mental health was not found after 6 and 12 months’ unemployment, and the four measurements of mental health at registration did not predict employment status 6 and 12 months later. Results are discussed in terms of moderating variables that capture Luxembourg labor market specificities.

By gene targeting, we have recently generated mice expressing a functionally inactive mutant vitamin D receptor (VDR). After a change in environmental conditions from specific pathogen free (SPF) conditions to a modified barrier system, a high percentage of aged mutant, but not wild-type, mice developed a haematological disorder characterized by splenomegaly, granulocytosis, thrombocytosis and dysplastic changes with displacement of erythropoiesis in bone marrow during the following months. All cases were associated with very high serum levels of the acute phase reaction protein serum amyloid A (SAA). Serological testing of affected mice revealed antibodies against murine hepatitis virus (MHV). However, electron microscopy of spleen and bone marrow cells did not reveal virus particles, and clinical signs of infectious diseases were absent. We hypothesize that a non-functioning VDR is associated with a latent defect in the regulation of myeloid cell differentiation and proliferation. Under the conditions of environmental stress, this latent defect may predispose to a deregulation of myelopoiesis in the form of a leukaemoid reaction accompanied by dysplastic changes. Thus, 1,25(OH)(2)D(3) may be an important inhibitory factor in the onset and progression of myeloproliferative and myelodysplastic diseases urn:issn:0278-0232 Hematological Oncology, 28 (4), 185-191 (2010)

While the dermomyotome gives rise to dermis and muscle, the sclerotome differentiates into cartilage and bone of the axial skeleton. The onset of muscle differentiation can be visualized by immunohistochemistry for proteins associated with muscle contractility, e.g. desmin. The sclerotome cells and the epithelial ventral half of the somite express Pax-1, a member of a gene family with a sequence similarity to Drosophila paired-box-containing genes. In the present study, changes of Pax-1 expression were studied after grafting an additional notochord into the paraxial mesoderm region. The influence of the notochord and the floor-plate on dermomyotome formation and myotome differentiation has also been investigated. The notochord is found to exert a ventralizing effect on the establishment of the dorso-ventral pattern in the somites. Notochord grafts lead to a suppression of the formation and differentiation of the dorsal somitic derivatives. Simultaneously, a widening of the Pax-1-expressing domain in the sclerotome can be observed. In contrast, grafted roof-plate and aorta do not interfere with dorso-ventral patterning of the somitic derivatives. urn:issn:0340-2061 urn:issn:1432-0568 Anatomy & Embryology, 188 (3), 239-45 (1993)

The gene responsible for un has been identified as the Pax-1 gene, a member of the Pax-gene family. A human disease homologue to un is not known so far. In order to facilitate identification of a potential human PAX-1 disease, an overview is given describing what is currently known about the pathological and molecular analysis of un.

We have cloned the avian Pax-1 gene as a basis for experimental studies of the induction of Pax-1 in the paraxial mesoderm. The amino acid sequence of the paired-domain is exactly the same in the quail and mouse, whereas outside the paired-domain there is 61% homology. Starting at about the eight-somite stage, quail Pax-1 is expressed in the paraxial mesoderm in a craniocaudal sequence. The unsegmented paraxial mesoderm and the two most recently formed somites do not express Pax-1. In the epithelial somite, the somitocoele cells and the cells of the ventral two-thirds of the epithelial wall are positive. As soon as the sclerotome is formed, only a subset of sclerotome cells expresses Pax-1. These are the cells that migrate towards the notochord to form the perinotochordal tube. Expression then becomes restricted to the intervertebral discs, the perichondrium of the vertebral bodies and the connective tissue surrounding the spinal ganglia. Additional expression domains are found in the scapula and the pelvic region, distinct areas of the head, and the epithelium of the second to the fourth visceral pouch. In later stages the thymus is positive. In vitro and in vivo experiments show that the notochord induces Pax-1 in the paraxial mesoderm, but limb bud mesoderm is not competent to respond to notochordal signals. Floor plate is also capable of inducing Pax-1 expression in sclerotome cells. Our studies show that in competent cells of the paraxial mesoderm, Pax-1 is a mediator of signals emanating from the notochord and the floor plate. urn:issn:0340-2061 urn:issn:1432-0568 Anatomy & Embryology, 191 (4), 297-310 (1995)

We have cloned and sequenced the SOX10 and Sox10 genes from human and mouse, respectively. Both genes encode proteins of 466 amino acids with 98% sequence identity. Significant expression of the 2.9-kb human SOX10 mRNA is observed in fetal brain and in adult brain, heart, small intestine and colon. Strong expression of Sox10 occurs throughout the peripheral nervous system during mouse embryonic development. SOX10 shows an overall amino acid sequence identity of 59% to SOX9. Like SOX9, SOX10 has a potent transcription activation domain at its C-terminus and is therefore likely to function as a transcription factor. Whereas SOX9 maps to 17q, a SOX10 cosmid has previously been mapped by us to the region 22q13.1.

[1994] Development 120:2773-2785; Ebensperger et al. [1995] Anat. Embryol. 191:297-310). In dorsoventral patterning of Drosophila, expression of pox meso, an insect gene with high sequence similarity to Pax1, is repressed by decapentaplegic (dpp) in dorsal mesoderm and, thus, is restricted to a discrete ventral domain (Staehling-Hampton et al. [1994] Nature 372:783-786). In the chick wing, cells expressing a vertebrate homolog of dpp, bone morphogenetic protein 4 (Bmp4), abut the Pax1 domain, suggesting a similar relationship between homologous genes in both vertebrates and invertebrates. Here, we show that two BMPs (BMP4, and BMP2, also highly related to dpp) can repress Pax1 in the developing chick wing. Chick wing bud cells expressing Pax1 give rise to the shoulder girdle. Cells in an equivalent position in the mouse forelimb also express Pax1, and Pax1 mutant mice display shoulder girdle defects. Similarly in chick embryos, girdle defects are produced by treatments with signalling molecules that lead to expression of BMPs, which subsequently reduce Pax1 expression in the limb bud. Recently, BMP4 has been shown to inhibit Pax1 expression in the developing trunk (Monsoro-Burq et al. [1996] Development 122:3607-3616) and Pax9 expression in developing teeth (Neubuser et al. [1997] Cell 90:247-255). Thus, a property of BMPs appears to be to regulate pox meso homologs negatively and, thus, limit their expression domains. urn:issn:1058-8388 Developmental Dynamics : An Official Publication of the American Association of Anatomists, 213 (2), 199-206 (1998)

Based on scanning electron microscopy (SEM) studies, Tlc clearly plays a developmental role in the hair cells of the cochlea since the stereocilia bundles fail to form the characteristic V-shape pattern around the time of birth. By young adult stages, Tlc/+ outer hair bundles are grossly disorganised although inner hair bundles appear relatively normal by SEM. Increased compound action potential thresholds revealed that the Tlc/+ cochlear hair cells were not functioning normally in young adults. Similar to inner hair cells, the hair bundles of the vestibular hair cells also do not appear grossly disordered. However, all types of hair cells in the Tlc/+ inner ear eventually degenerate, apparently regardless of the degree of organisation of their hair bundles. We have mapped the Tlc mutation to a 12 cM region of chromosome 2, between D2Mit164 and D2Mit423. Based on the mode of inheritance and map location, Tlc appears to be a novel mouse mutation affecting both hair cell survival and stereocilia bundle development. urn:issn:0300-4864 Journal of Neurocytology, 28 (10-11), 969-85 (1999)

Chondrocyte-specific gene expression is downregulated by RA, and PCR-amplified cDNAs from both untreated and RA-modulated cells were differentially displayed. Amplification products only from RNA of untreated chondrocytes were further analyzed, and a cDNA-fragment of the chondromodulin-I (ChM-I) mRNA was isolated. After obtaining full length cDNA clones, we have analyzed the mRNA expression patterns at different developmental stages by RNase protection assay and in situ hybridization. Analysis of different tissues and cartilage from 17-day-old chicken embryos showed ChM-I mRNA only in chondrocytes. During somitogenesis of the chicken embryo, ChM-I transcripts were detected in the notochord, the floor and the roof plate of the neural tube, and in cartilage precursor tissues such as the sclerotomes of the somites, the developing limbs, the pharyngeal arches, the otic vesicle, and the sclera. ChM-I continued to be expressed in differentiated cartilages derived from these tissues and also in noncartilaginous domains of the developing heart and retina. Thus, in the chicken, the expression of ChM-I is not restricted to mature cartilage but is already present during early development in precartilaginous tissues as well as in heart and eye. urn:issn:1058-8388 Developmental Dynamics : An Official Publication of the American Association of Anatomists, 216 (3), 233-43 (1999)

Homologous recombination in embryonic stem cells allows the systematic production of mouse mutants for any gene that has been cloned. Gene trap strategies have been designed to interrupt even unknown genes which are tagged by the inserted vector and can be characterised structurally and functionally. Complementary to such 'gene-driven' approaches, 'phenotype-driven' approaches are necessary to identify new genes or gene products through a search for mutants with specific defects, uncovering the function of genetic pathways in physiological and pathological processes. Mutagenesis using the alkylating agent N-ethyl-N-nitrosourea (ENU) is a powerful approach for the production of such mouse mutants. Since ENU induces mainly point mutations in premeiotic spermatogonia, this strategy allows the production of multiple alleles of a particular gene, which is pivotal for a fine tuned analysis of its function. urn:issn:0958-0670 Experimental Physiology, 85 (6), 635-44 (2000)

On the basis of the chromosomal position, the gamma-crystallin encoding gene cluster (Cryg) and the betaA2-crystallin encoding gene Cryba2 were tested as candidate genes. An A --> T mutation destroys the start codon of the Cryge gene in the mutants; this mutation was confirmed by the absence of a restriction site for NcoI in the corresponding genomic fragment of homozygous mutants. The next in-frame start codon is 129 bp downstream; this predicted truncated gammaE-crystallin consists of 131 amino acids, resulting in a molecular mass of 14 kD. However, another open reading frame was observed just 19 bp downstream of the regular Cryge start codon, resulting in a protein of 119 amino acids and a calculated molecular weight of 13 kD. Western blot analysis using polyclonal antibodies against gamma-crystallins or the novel Aey1-specific protein demonstrated the specific expression of the Aey1 protein in the cataractous lenses only; the truncated form of the gammaE-crystallin could not be detected.

The cataractous phenotype is visible at the eye opening and progresses to a nuclear and zonular cataract at 2 months of age with no difference in onset or severity between heterozygous and homozygous mutants. Histological analysis revealed that fiber cell differentiation continues at the lens bow region, but the cell nuclei do not degrade normally and remain in the deeper cortex. Further, the lens nucleus has clefts of various sizes while the remainder of the eye was morphologically normal. The mutation was mapped to chromosome 3 between the markers D3Mit101 and D3Mit77 near the connexin encoding genes Gja5 and Gja8. Sequence analysis revealed no differences in the Gja5 gene, but identified a T-->C mutation at position 191 in the Gja8 gene, which was confirmed by an additional Mva 12691 restriction site in the genomic DNA of homozygous mutants. This mutation results in Val-->Ala substitution at codon 64 of connexin50 (Cx50) also known as lens membrane protein 70 (MP70). Aey5 represents the second dominant mouse cataract mutant affecting Cx50, a membrane protein preferentially expressed in the lens. Since both mutations affect similar regions in the first extracellular domain this region appears to be critically important for its function in lens transparency. urn:issn:0014-4835 Experimental Eye Research, 73 (6), 867-76 (2001)

We show that the ratio of the vertical displacement to the horizontal displacement, combined with the direction of the horizontal motion, can help determine whether nearby loading is concentrated in a small region (for example, in a single lake or glacier), and where that region is. We illustrate this method by applying it to two specific cases: an analysis of GPS data from northern California to monitor the level of Lake Shasta, and the analysis of data from a single GPS site in southeast Greenland to determine mass variability of two large, nearby outlet glaciers: Helheim Glacier and Midgaard Glacier. The California example serves largely as a proof-of-concept, where the results can be assessed by comparing with independent observations (Lake Shasta tide gauge data, in this case). Our Greenland results show that both Helheim and Midgaard have experienced notable interannual variations in mass loss rate over the last decade. Helheim’s mass loss accelerated rapidly in mid-2003, decelerated in late 2005, and increased again in 2008–2009 before returning to about its pre-2003 rate in late 2010. Midgaard’s mass loss accelerated in mid-2004, and remained more-or-less constant before returning to its pre-2003 rate in late 2008. urn:issn:0148-0227 Journal of Geophysical Research.

The only previous global analysis investigating the magnitude of OBP surface displacements used older OBP data sets (van Dam et al. in J Geophys Res 129:507–517, 1997). Since then significant improvements in meteorological forcing models used to predict OBP have been made, augmented by observations from satellite altimetry and expendable bathythermograph profiles. Using more recent OBP estimates from the Estimating the Circulation and Climate of the Ocean (ECCO) project, we reassess the amplitude of the predicted effect of OBP on the height coordinate time series from a global distribution of GPS stations. OBP-predicted loading effects display an RMS scatter in the height of between 0.2 and 3.7 mm, larger than previously reported but still much smaller (by a factor of 2) than the scatter observed due to atmospheric pressure loading. Given the improvement in GPS hardware and data analysis techniques, the OBP signal is similar to the precision of weekly GPS height coordinates. We estimate the effect of OBP on GPS height coordinate time series using the MIT reprocessed solution, mi1. When we compare the predicted OBP height time series with mi1, we find that the scatter is reduced over all stations by 0.1 mm on average with reductions as high as 0.7 mm at some stations. More importantly we are able to reduce the scatter on 65 % of the stations investigated. The annual component of the OBP signal is responsible for 80 % of the reduction in scatter on average.We find that stations located close to semi-enclosed bays or seas are affected by OBP loading to a greater extent than other stations. urn:issn:0949-7714 Journal of Geodesy, 86 (11), 1043-1057 (2012)

This is usually done by estimating the parameters of a linearized similarity transformation which relates the quasi-instantaneous frames to a long-term frame such as the International Terrestrial Reference Frame (ITRF). It is well known that non-linear station motions can partially alias into these parameters. We discuss in this paper some procedures that may allow reducing these aliasing effects in the case of the GPS techniques. The options include the use of well-distributed sub-networks for the frame transformation estimation, the use of site loading corrections, a modification of the stochastic model by downweighting heights, or the joint estimation of the low degrees of the deformation field. We confirm that the standard approach consisting of estimating the transformation over the whole network is particularly harmful for the loading signals if the network is not well distributed. Downweighting the height component, using a uniform sub-network, or estimating the deformation field perform similarly in drastically reducing the amplitude of the aliasing effect. The application of these methods to reprocessed GPS terrestrial frames permits an assessment of the level of agreement between GPS and our loading model, which is found to be about 1.5 mm WRMS in height and 0.8 mm WRMS in the horizontal at the annual frequency. Aliased loading signals are not the main source of discrepancies between loading displacement models and GPS position time series. urn:issn:0949-7714 Journal of Geodesy, 86 (1), 1-14 (2012)

We analyse determinants of non-voting both on the individual and the societal level employing a multilevel design. On the micro level, the sociological determinants under consideration are education, cohort and gender. Regarding psychological or motivational factors, we include in the analyses political efficacy, political interest, political trust and satisfaction with politics. On the macro level, we analyse characteristics of the electoral system, including opportunities for ‘direct democracy’, maturity of democracy, disproportionality factor, and if the participation in elections is compulsory. The data source of the analyses is the European Social Survey 2006. A first main finding is the fact that the probability of non-voting is higher among people with a low level of education and among younger cohorts. The motivational factors have similar impacts on non-voting across all analysed societies. Lack of political efficacy, lack of political interest, lack of political trust and dissatisfaction with politicians and the political system increase the probability of non-voting. Regarding macro influences, countries with compulsory voting and ‘old democracies’ turn out to have a lower rate of non-voting, although these effects vanish when simultaneously modelled with the social psychological micro level indicators. urn:issn:1461-6696 European Societies, 12 (4), 521-542 (2010)

Im Ergebnis zeigen sich gleich bleibend starke Effekte des Bildungsniveaus sowie Hinweise, dass eine politische Mobilisierung stattgefunden hat. urn:issn:0023-2653 Kolner Zeitschrift für Soziologie und Sozialpsychologie, 59 (3), 410-439 (2007)

In this paper a pyruvate-auxotrophic Escherichia coli-strain is utilized in order to activate alternative pyruvate synthesis pathways via evolutive adaptation. The outcome of the chemostat experiments are pyruvateprototrophic strains. Due to the activated alternative synthesis pathways, these strains are a basis for future industrial production-strains in order to systematically produce the intermediate products on these pathways. By means of a simple dynamical model of a chemostat, the evolutive adaptation in chemostat mode is studied. Rules to adjust the feeding concentration and the dilution rate of the bioreactor could be obtained in order to accelerate the evolutive adaptation towards a pyruvate-prototrophic strain. A flux balance analysis of the metabolic network of the pyruvate-auxotrophic strain results in 20 different alternative pathways. For a well arranged presentation of those pathways a reduced visualization method is introduced. Die biotechnische Herstellung von Substanzen mit Hilfe von Mikroorganismen ist ein wirtschaftlich wichtiges Einsatzgebiet der Systembiologie. In diesem Artikel wird ein pyruvatauxotropher Escherichia coli-Stamm eingesetzt, um durch evolutive Adaptation alternative Stoffwechselwege zum Pyruvat zu aktivieren. Das Ergebnis der Experimente sind pyruvatprototrophe Stämme, die mit ihren alternativen Stoffwechselwegen als Grundlage für Produktionstämme eingesetzt werden können, um später damit gezielt in diesen Wegen auftretende Zwischenprodukte industriell herzustellen. Mit Hilfe eines einfachen dynamischen Modells wird die evolutive Adaptation im Chemostat untersucht. Es können dabei Einstellregeln für die Zulaufkonzentration und Verdünnungsrate im Bioreaktor zur beschleunigten Gewinnung pyruvat-prototropher Stämme geschlussfolgert werden. Die Flussbilanzanalyse des metabolischen Netzwerkes des pyruvat-auxotrophen Stammes ergibt 20 verschiedene alternative Flussverteilungen. Zur übersichtlichen Darstellung solcher Flussverteilungen wird eine reduzierte Visualisierungsmethode vorgestellt. urn:issn:0178-2312 Automatisierungstechnik, 56, 257-268 (2008)
