Disorder-induced electronic, magnetic, and optoelectronic properties of two-dimensional materials

Technological advancement has been in cadence with material development by improving the purity of single crystals and, at the same time, controlling their imperfections. These capabilities have been especially vital for developing new technolo-gies based ...

Maladaptive emotion regulation traits predict altered corticolimbic recovery from psychosocial stress

Dimitri Nestor Alice Van De Ville

Background: Adaptive recovery from stress promotes healthy cognitive affective functioning, whereas maladaptive recovery is linked to poor psychological outcomes. Neural regions, like the anterior cingulate and hippocampus, play critical roles in psychosoc ...

Interventions for Softening Can Lead to Hardening of Opinions: Evidence from a Randomized Controlled Trial

Robert West, Andreas Oliver Spitz, Ahmad Abu-Akel

Motivated by the goal of designing interventions for softening polarized opinions on the Web, and building on results from psychology, we hypothesized that people would be moved more easily towards opposing opinions when the latter were voiced by a celebri ...

A Role for Human DNA Polymerase λ in Alternative Lengthening of Telomeres

Joachim Lingner, Liuh-Yow Chen

Telomerase negative cancer cell types use the Alternative Lengthening of Telomeres (ALT) pathway to elongate telomeres ends. Here, we show that silencing human DNA polymerase (Pol λ) in ALT cells represses ALT activity and induces telomeric stress. In addi ...

Electrochemical Stability of the Reconstructed Fe3O4(001) Surface

Klaus Kern

Establishing the atomic-scale structure of metal-oxide surfaces during electrochemical reactions is a key step to modeling this important class of electrocatalysts. Here, we demonstrate that the characteristic (root 2x root 2)R45 degrees surface reconstruc ...

Energetics of turbulence generated by chiral MHD dynamos

Jennifer Waltraud Schober

An asymmetry in the number density of left- and right-handed fermions is known to give rise to a new term in the induction equation that can result in a dynamo instability. At high temperatures, when a chiral asymmetry can survive for long enough, this chi ...

Three Essays on Predictability and Seasonality in the Cross-Section of Stock Returns

Vincent Jean Bogousslavsky

This thesis examines predictability and seasonality in the cross-section of stock returns. The first chapter, titled ``Infrequent Rebalancing, Return Autocorrelation, and Seasonality,'' shows that a model of infrequent rebalancing can explain specific pred ...

Backward masking performance in patients with functional psychoses

Michael Herzog, Maya Roinishvili

In visual backward masking, a target is followed by a blank screen (ISI - Inter-stimulus-interval) and, then, a mask which deteriorates target processing. Schizophrenic patients show strong but complex processing deficits in visual masking compared to heal ...

The electrophysiological effects of the serotonin 1A receptor agonist buspirone in emotional face processing

Fosco Bernasconi

Emotional face processing is critically modulated by the serotonergic system, and serotonin (5-HT) receptor agonists impair emotional face processing. However, the specific contribution of the 5-HT1A receptor remains poorly understood. Here we investigated ...

Impaired hippocampal neuroligin-2 function by chronic stress or synthetic peptide treatment is linked to social deficits and increased aggression

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Michael van der Kooij, Martina Fantin

Neuroligins (NLGNs) are cell adhesion molecules that are important for proper synaptic formation and functioning and are critical regulators of the balance between neural excitation/inhibition (E/I). Mutations in NLGNs have been linked to psychiatric disor ...

Different emotional disturbances in two experimental models of temporal lobe epilepsy in rats

Maria del Carmen Sandi Perez

Affective symptoms such as anxiety and depression are frequently observed in patients with epilepsy. The mechanisms of comorbidity of epilepsy and affective disorders, however, remain unclear. Diverse models are traditionally used in epilepsy research, inc ...

Patients with functional psychoses show similar visual backward masking deficits

Michael Herzog, Maya Roinishvili

Recent genetic, behavioral, and clinical studies suggest that functional psychoses (schizophrenia, bipolar disorder, schizoaffective disorder), previously thought to be distinct from each other, may belong to one continuum. The shine-through masking paradi ...

Backward masking reveals different visual processing of schizophrenic and depressive patients

Michael Herzog, Maya Roinishvili

Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...

Effects of hardware heterogeneity on the performance of SVM Alzheimer's disease classifier

Bénédicte Marie Maréchal, Ahmed Abdulkadir, Gunnar Krüger

Fully automated machine learning methods based on structural magnetic resonance imaging data can assist radiologists in the diagnosis of Alzheimer's disease (AD). These algorithms require large data sets to learn the separation of subjects with and without ...

Controlling the charge environment of single quantum dots in a photonic-crystal cavity

Laurent Balet, Blandine Alloing, Carl Zinoni

We demonstrate that the presence of charges around a semiconductor quantum dot (QD) strongly affects its optical properties and produces nonresonant coupling to the modes of a microcavity. We show that, besides (multi)exciton lines, a QD generates a spectr ...

Teaching a Humanoid: A User Study on Learning by Demonstration with HOAP-3

Aude Billard, Sylvain Calinon

This article reports on the results of a user study investigating the satisfaction of naïve users conducting two learning by demonstration tasks with the HOAP-3 robot. The main goal of this study was to gain insights on how to ensure a successful as well a ...
