Genomic drift affects the functional properties of cell lines, and the reproducibility of data from in vitro studies. While chromosomal aberrations and mutations in single pivotal genes are well explored, little is known about effects of minor, possibly pleiotropic, genome changes. We addressed this question for the human dopaminergic neuronal precursor cell line LUHMES by comparing two subpopulations (SP) maintained either at the American-Type-Culture-Collection (ATCC) or by the original provider (UKN). Drastic differences in susceptibility towards the specific dopaminergic toxicant 1-methyl-4-phenylpyridinium (MPP+) were observed. Whole-genome sequencing was performed to identify underlying genetic differences. While both SP had normal chromosome structures, they displayed about 70 differences on the level of amino acid changing events. Some of these differences were confirmed biochemically, but none offered a direct explanation for the altered toxicant sensitivity pattern. As second approach, markers known to be relevant for the intended use of the cells were specifically tested. The “ATCC” cells rapidly down-regulated the dopamine-transporter and tyrosine-hydroxylase after differentiation, while “UKN” cells maintained functional levels. As the respective genes were not altered themselves, we conclude that polygenic complex upstream changes can have drastic effects on biochemical features and toxicological responses of relatively similar SP of cells.

Majorana bound states have been proposed as building blocks for qubits on which certain operations can be performed in a topologically protected way using braiding. However, the set of these protected operations is not sufficient to realize universal quantum computing. We show that the electric field in a microwave cavity can induce Rabi oscillations between adjacent Majorana bound states. These oscillations can be used to implement an additional single-qubit gate. Supplemented with one braiding operation, this gate allows us to perform arbitrary single-qubit operations. [less ▲]

Parkinson's disease is characterized by a selective loss of dopaminergic neurons in the substantia nigra (SN). However, whether regenerative endogenous neurogenesis is taking place in the mammalian SN of parkinsonian and non-parkinsonian brains remains of debate. Here, we tested whether proliferating cells in the SN and their neurogenic potential would be affected by anti-inflammatory treatment under physiological conditions and in the 6-hydroxy-dopamine (6-OHDA) Parkinson's disease mouse model. We report that the majority of newly generated nigral cells are positive for Doublecortin (Dcx), which is an often used marker for neural progenitor cells. Yet, Dcx expression levels in these cells were much lower than in neural progenitor cells of the subventricular zone and the dentate gyrus neural progenitor cells. Furthermore, these newly generated nigral cells are negative for neuronal lineage markers such as TuJ1 and NeuN. Therefore, their neuronal commitment is questionable. Instead, we found evidence for oligodendrogenesis and astrogliosis in the SN. Finally, neither short-term nor long-term inhibition of neuroinflammation by Minocycline- or 6-OHDA-induced lesion affected the numbers of newly generated cells in our disease paradigm. Our findings of adult generated Dcx+ cells in the SN add important data for understanding the cellular composition and consequently the regenerative capacity of the SN. [less ▲]

Beamforming with large-scale antenna arrays (LSAA) is one of the predominant operations in designing wireless communication systems. However, the implementation of a fully digital system significantly increases the number of required radio-frequency (RF) chains, which may be prohibitive. Thus, analog beamforming based on a phase-shifting network driven by a variable gain amplifier (VGA) is a potential alternative technology. In this paper, we cast the beamforming vector design problem as a beampattern matching problem, with an unknown power gain. This is formulated as a unit-modulus least-squares (ULS) problem where the optimal gain of the VGA is also designed in addition to the beamforming vector. We also consider a scenario where the receivers have the additional processing capability to adjust the phases of the incoming signals to mitigate specular multipath components. We propose efficient majorization-minimization (MM) based algorithms with convergence guarantees to a stationary point for solving both variants of the proposed ULS problem. Numerical results verify the effectiveness of the proposed solution in comparison with the existing state-of-the-art techniques. [less ▲]

Le développement d’Internet met en avant des acteurs multiples et s’inscrit dans une co-construction favorable à l’innovation ascendante.Celle-ci mobilise cependant des « usagers » aux statuts très contrastés, allant des amateurs passionnés aux utilisateurs très « éclairés » que sont, par exemple, certains chercheurs. L’émergence de l’Internet en France permet d’observer ces frontières imprécises entre monde des producteurs d’innovation et sphères des « utilisateurs », le cas de l’Inria étant à cet égard particulièrement éclairant.

Humean reductionism about laws of nature appears to leave a central aspect of scientific practice unmotivated: If the world’s fundamental structure is exhausted by the actual distribution of non-modal properties and the laws of nature are merely efficient summaries of this distribution, then why does science posit laws that cover a wide range of non-actual circumstances? In this paper, we develop a new version of the Humean best systems account of laws based on the idea that laws need to organize information in a way that maximizes their cognitive usefulness for creature like us. We argue that this account motivates scientific practice because the laws’ applicability to non-actual circumstances falls right out of their cognitive usefulness. [less ▲]

This paper focuses on the diversity of care arrangements of 2- to 4-year-old children in Luxembourg. In line with a childhood-sociological perspective on day care childhood as a socio-structural form and a way of living, those care arrangements are viewed as unique spaces of ECEC because they are the ‘places’ where day care policies, local structures, parents’ beliefs and choices, institutional orders and children’s activities and daily travels merge and interrelate. The part of the CHILD study presented in this article asks how this relations are embedded in and facilitated by spatial practices which create the distinct places of positioning and agency for children. The research questions, methodologies and methods of the CHILD study are introduced and discussed using one empirical example from the ongoing process of writing ‘thick portraits’ of each of the 12-15 case studies, the CHILD study aims to complete.

Whereas 18th and 19th century developments in efficient labor production called for versatility and wide-ranging skills, that is, qualities of “completeness,” 20th century means of efficient production ushered in a general shift towards Taylorism, or specialization. This shift impacted on the field of sport. Thus, by the early 20th century more and more athletes turned towards concentrating their training on a single sport. This, of course, consequently led to a decrease in multiple sports skills. Astonishingly, in the midst of this accelerating trend, a new combined sport, the Modern Pentathlon, was introduced into the Olympic program in 1912. The Modern Pentathlon, composed of shooting, fencing, swimming, horse-riding, and running required all-around instead of one-dimensional abilities, diversity instead of specialization. Pierre de Coubertin promoted the sport as a tool for an individual to reach “completeness,” thereby emphasizing the possibility of enriching human lives through multidimensional practices. By investigating sources in the IOC Archives in Lausanne, the National and Military Archives of Sweden in Stockholm, and the National Library of France in Paris, this essay aims to analyze the history of the ideal of “completeness” related to the Modern Pentathlon. It explores whether in a time of increasing specialization the skills developed through Modern Pentathlon functioned as a contemporary ideal of human achievement. [less ▲]
