This paper introduces the paired lasso: a generalisation of the lasso for paired covariate settings. Our aim is to predict a single response from two high-dimensional covariate sets. We assume a one-to-one correspondence between the covariate sets, with each covariate in one set forming a pair with a covariate in the other set. Paired covariates arise, for example, when two transformations of the same data are available. It is often unknown which of the two covariate sets leads to better predictions, or whether the two covariate sets complement each other. The paired lasso addresses this problem by weighting the covariates to improve the selection from the covariate sets and the covariate pairs. It thereby combines information from both covariate sets and accounts for the paired structure. We tested the paired lasso on more than 2000 classification problems with experimental genomics data, and found that for estimating sparse but predictive models, the paired lasso outperforms the standard and the adaptive lasso. The R package palasso is available from CRAN. [less ▲]

Dark personality traits (i.e., Machiavellianism, psychopathy, narcissism, spitefulness, and sadism) are associated with adverse childhood experiences and deviant online behaviors. However, their mediating role between childhood emotional abuse and cyberbullying has never previously been investigated. We examined direct and indirect associations of childhood emotional abuse and cyberbullying via dark personality traits among 772 participants. Men were better characterized by dark personality traits and were more likely to engage in cyberbullying than women, and there were no sex differences in childhood emotional abuse. Collectively, dark traits fully mediated the relationship between childhood emotional abuse and cyberbullying in men, with partial mediation in the total sample and women. More specifically, Machiavellianism and spitefulness were mediators in both samples, sadism was a mediator in men and the total sample, and psychopathy was a mediator in the total sample and women. The dark personality traits can account for the association between childhood emotional abuse and cyberbullying, especially among men. [less ▲]

In this paper, a new computational approach, which is based on a multi-physics coupling of the chemo-thermo-mechanical process, is developed for modeling failure mechanism in cement-based materials at early-age hydration. A new constitutive law describing mechanical behavior of young concrete is thus derived, taking into account the effects of several factors including thermal expansion, shrinkage, damage, and both basic and transient thermal creeps. A strongly coupled model describing the interaction between fracture and multi-physics problems of cement hydration is obtained. The present phase field model in terms of smeared crack approach is highly suitable for simulating crack, especially when considering the unilateral contact conditions at crack surfaces. The capability of the proposed model in modeling complex crack initiation and propagation under arbitrary boundary conditions is highlighted. Fracture phenomena at both macroscopic and mesoscopic scales are considered and analyzed. The effects of creep and microstructural heterogeneity in different length scale are investigated, showing the great potential of the developed approach. [less ▲]

This Perspective surveys the state-of-the-art and future prospects of science and technology employing the nanoconfined light (nanophotonics and nanoplasmonics) in combination with magnetism. We denote this field broadly as nanoscale magnetophotonics. We include a general introduction to the field and describe the emerging magneto-optical effects in magnetoplasmonic and magnetophotonic nanostructures supporting localized plasmons. Special attention is given to magnetoplasmonic crystals with transverse magnetization and the associated nanophotonic nonreciprocal effects, and to magneto-optical effects in nanostructure’s periodic arrays. We also give an overview of the applications of these systems in biological and chemical sensing, as well as in light polarization and phase control. We further review the area of nonlinear magnetophotonics, the semiconductor spin-plasmonics, and the general principles and applications of optomagnetism and nano-optical ultrafast control of magnetism and spintronics.

The effective enforcement of rights within the European Union, understood as a legal system overarched by the duty of loyalty, depends upon judicial independence. This chapter introduces some recent legal developments pertaining to its double dimension as a fundamental right and as a structural duty of the Member states to discuss four enforcing tools that concretise the duty of loyalty: the self-standing right to an independent tribunal, the infringement procedure, the preliminary ruling procedure and the technique of exceptional circumstances. In that context, the chapter rejects the idea that the multifaceted configuration of the European Union is detrimental to fundamental rights protection and stresses the relevance of all the actors of the legal system for the effective enforcement of rights.

In Deutschland ist, wie in den meisten anderen Ländern Europas, eine Debatte über die Auflösung der traditionellen Dichotomie von Sonder- versus Regelschule zu beobachten. Diese Debatten reflektieren, dass die derzeitige Lage im deutschen Schulsystem keineswegs einer Realisierung des Menschenrechts auf inklusive Bildung entspricht, wie es in Artikel 24 der UN-BRK verankert ist. Inklusive Bildung wird hier als gemeinsames Lernen an allgemeinen Schulen in allen Bildungsstufen definiert. Inklusion ist demnach weder vereinbar mit Sonderbeschulung (Segregation), Unterricht in separaten Klassen und Lerngruppen an allgemeinen Schulen (Separation) noch mit Unterricht, wel- cher zwar größtenteils gemeinsam stattfindet, jedoch nicht auf Vielfalt jeglicher Art ausgerichtet ist (etwa Schicht, Geschlecht, Migrationshintergrund, Behinderung) (Integration) (Committee on the Rights of Persons with Disabilities, 2016, S. 3). Die Institutionalisierung inklusiver Bildung setzt also eine De-Institutionalisierung segregierter und separierter Schulsysteme voraus (Biermann & Powell, 2014). Auf Grundlage dieses Verständnisses hat der UN Ausschuss für die Rechte von Menschen mit Behinderungen im Rahmen des Staatenberichtsverfahrens im Jahr 2015 auch die Entwicklungen in Deutschland kritisiert (Committee on the Rights of Persons with Disabilities, 2015, S. 8). Eine Transformation hin zu einem inklusiven Bildungssystem, in dem alle Schüler*innen möglichst lange gemeinsam lernen, hat es bisher nur regional bedingt gegeben (Autorengruppe Bildungsberichterstattung, 2014, 2016, 2018; Blanck, Edelstein & Powell, 2013). Obwohl sonderpädagogische Förderung je nach Bundesland und Kreis an sehr unterschiedlichen Lernorten bereitgestellt wird, ist im Aggregat dennoch die Persistenz der Sonderbeschulung nicht zu verleugnen (Autorengruppe Bildungsberichterstattung, 2014, 2016, 2018; Blanck, Edelstein & Powell, 2013). In den verschiedenen Regionen Deutschlands kommt es daher weder zu einer allgemeinen Angleichung der Lebensbedingungen noch zu einer Konvergenz in den Bildungschancen. Dies hat weitreichende Folgen für die gegenwärtige Schüler*innengeneration und nimmt negativen Einfluss auf individuelle Bildungskarrieren. Die Frage, mit welcher wir uns in diesem Beitrag beschäftigen, lautet daher: Welche Wirkung hat der völkerrechtlich anerkannte Auftrag, inklusive Bildung zu gewährleisten, auf das deutsche Schulsystem?

Climate change poses one of the greatest challenges on an international scale. Responding to this challenge requires the collective effort of all States, however, primary burden has been placed on climate finance deriving from developed States, reflecting a dichotomy amongst the member States to the UN climate change regime. The climate finance obligation, albeit justified under the UNFCCC and the principle of differentiation, does not come without challenges for both categories of States. Most of these challenges have focused so far on the donor side, as well as the institutional design and policy weaknesses of the development institutions administering and disbursing climate finance. Considerable challenges, however, also exist on the beneficiary side, especially due to the lack of national climate finance readiness and solid institutional frameworks and policies in recipient countries. This paper focuses on the legal aspects of readiness for climate finance examining the regulatory tools currently deployed by developing States to strengthen their domestic capacities. First, it elaborates on the climate finance obligation per se, while embarking on analyzing this obligation and the challenges it entails under the UN climate change framework. Second, it examines the concept of legal readiness by analyzing what it means to be ready for climate finance, the rationale of legal readiness and the role of law in enhancing developing States’ readiness for climate finance. In doing so, the paper elaborates on the existing taxonomies and guidelines on legal readiness for climate finance, as well as the regulatory and policy tools extensively utilized for this purpose in developing countries. Third, the paper demonstrates the case study of Bangladesh as a country that has advanced and adjusted its national legislation and policies, in order to enhance its legal readiness for climate finance.

We propose a novel methodology for designing oversampled discrete Fourier transform-modulated uniform filter banks. The analysis prototype is designed as a Nyquist filter, whereas the synthesis prototype is designed to guarantee perfect reconstruction (PR) considering oversampling. The resulting optimization problem fits into the disciplined convex programming framework, as long as some convex objective function is employed, as the minimization of either the stop-band energy or the maximum deviation from a desired response. The methodology also accounts for near-PR multiplierless approximations of the prototype analysis and synthesis filters, whose coefficients are obtained in the sum-of-power-of-two (SOPOT) space. The quantized coefficients are computed using successive approximation of vectors, which is able to yield filters with a reduced number of SOPOT coefficients in a computationally efficient manner. The proposed methodology is especially appealing for supporting actual hardware deployments, such as modern digital transparent processors to be used in next-generation satellite payloads. [less ▲]

Recent advances in nanotechnology have prompted the need for tools to accurately and non-invasively manipulate individual nano-objects. Among the possible strategies, optical forces have been widely used to enable nano-optical tweezers capable of trapping or moving a specimen with unprecedented accuracy. Here, we propose an architecture consisting of a nanotip excited with a plasmonic vortex enabling effective dynamic control of nanoparticles in three dimensions. The structure illuminated by a beam with angular momentum can generate an optical field which can be used to manipulate single dielectric nanoparticles. We demonstrate that it’s possible to stably trap or push the particle from specific points, thus enabling a new platform for nanoparticle manipulation. [less ▲]

OBJECTIVES: We aimed to develop the transaddiction craving triggers questionnaire (TCTQ), which assesses the propensity of specific situations and contexts to trigger craving and to test its psychometric properties in alcohol use disorder (AUD). METHODS: This study included a sample of 111 AUD outpatients. We performed exploratory factor analysis (EFA) and calculated item-dimension correlations. Internal consistency was measured with Cronbach's alpha coefficient. Construct validity was assessed through Spearman correlations with craving, emotional symptoms, impulsivity, mindfulness, and drinking characteristics. RESULTS: The EFA suggested a 3-factor solution: unpleasant affect, pleasant affect, and cues and related thoughts. Cronbach's coefficient alpha ranged from .80 to .95 for the three factors and the total score. Weak positive correlations were identified between the TCTQ and drinking outcomes, and moderate correlation were found between the TCTQ and craving strength, impulsivity, anxiety, depression, and impact of alcohol on quality of life. CONCLUSIONS: The 3-factor structure is congruent with the well-established propensity of emotions and cues to trigger craving. Construct validity is supported by close relations between the TCTQ and psychological well-being rather than between the TCTQ and drinking behaviors. Longitudinal validation is warranted to assess sensitivity to change of the TCTQ and to explore its psychometric properties in other addictive disorders. [less ▲]
