Comparison of questionnaire items for discomfort glare studies in daylit spaces

Marilyne Andersen, Jan Wienold, Caroline Karmann, Sneha Jain, Clotilde Marie A Pierson, Geraldine Cai Ting Quek

When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...

A Stepwise Domain Adaptive Segmentation Network With Covariate Shift Alleviation for Remote Sensing Imagery

Yinlin Hu, Yunpeng Li, Jingyu Li, Rui Song

Semantic segmentation for remote sensing images (RSI) is critical for the Earth monitoring system. However, the covariate shift between RSI datasets under different capture conditions cannot be alleviated by directly using the unsupervised domain adaptatio ...

Dynamic functional brain networks underlying the temporal inertia of negative emotions

Dimitri Nestor Alice Van De Ville, Thomas William Arthur Bolton, Gwladys Rey, Julian Gaviria

Affective inertia represents the lasting impact of transient emotions at one time point on affective state at a subsequent time point. Here we describe the neural underpinnings of inertia following negative emotions elicited by sad events in movies. Using ...

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 ...

Forceful manipulation with micro air vehicles

Dario Floreano, Stefano Mintchev, Matthew Alfonso Estrada

Micro air vehicles (MAVs) are finding use across an expanding range of applications. However, when interacting with the environment, they are limited by the maximum thrust they can produce. Here, we describe FlyCroTugs, a class of robots that adds to the m ...

The Subjective Sensation of Synchrony: An Experimental Study

Pierre Magistretti, Joan Llobera Mahy, Delphine Preissmann

People performing actions together have a natural tendency to synchronize their behavior. Consistently, people doing a task together build internal representations not only of their actions and goals, but also of the other people performing the task. Howev ...

AniSAM & AniAvatar – Animated Visualizations of Affective States

Andreas Sonderegger

Tools that provide visual feedback about emotions to the user in the form of an avatar or an emoticon have become increasingly important. While a great deal of effort has already been put into the reliable and accurate automatic detection of emotions, only ...

Critical impact of Ehrlich-Schwobel barrier on GaN surface morphology during homoepitaxial growth

Nicolas Grandjean, Denis Martin, Lise Lahourcade, Nils Asmus Kristian Kaufmann

We discuss the impact of kinetics, and in particular the effect of the Ehrlich-Schwobel barrier (ESB), on the growth and surface morphology of homoepitaxial GaN layers. The presence of an ESB can lead to various self-assembled surface features, which stron ...

Lightning Location Systems and Interstroke Intervals: Effects of Imperfect Detection Efficiency

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Mirjana Stojilovic

Lightning location systems (LLSs) are often used to obtain parameters of lightning flashes. However, the imperfect detection efficiency (DE) of these systems affects the accuracy of the results. In this paper, we focus on the effects of the imperfect DE on ...

AC and Mechanical Loss Analysis of the ITER PF RF SULTAN Samples

Pierluigi Bruzzone, Boris Stepanov

Analysis of the AC and mechanical losses of PF RF ITER SULTAN sample test results has been performed. Measurements were provided by the gas flow colorimetric method before and after cyclic mechanical loads. The mechanical loss investigation was carried out ...

Stress pulls us apart: Anxiety leads to differences in competitive confidence under stress

Maria del Carmen Sandi Perez, Samuel Bendahan, Fiona Hollis, John Christian Thoresen, Lorenz Goette

Social competition is a fundamental mechanism of evolution and plays a central role in structuring individual interactions and communities. Little is known about the factors that affect individuals’ competitive success, particularly in humans. Key factors ...

Plant functional types define magnitude of drought response in peatland CO2 exchange

Luca Bragazza, Bjorn Jozef Maria Robroek

Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the ...

Unraveling dynamics of human physical activity patterns in chronic pain conditions

Kamiar Aminian, Anisoara Ionescu

Chronic pain is a complex disabling experience that negatively affects the cognitive, affective and physical functions as well as behavior. Although the interaction between chronic pain and physical functioning is a well-accepted paradigm in clinical resea ...

Unsupervised adaptation for acceleration-based activity recognition: Robustness to sensor displacement and rotation

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Hamidreza Bayati

A common assumption in activity recognition is that the system remains unchanged between its design and its posterior operation. However, many factors affect the data distribution between two different experimental sessions. One of these factors is the pot ...

Towards Unbiased BFS Sampling

Patrick Thiran, Maciej Kurant

Breadth First Search (BFS) is a widely used approach for sampling large graphs. However, it has been empirically observed that BFS sampling is biased toward high-degree nodes, which may strongly affect the measurement results. In this paper, we quantify an ...

AdS/QCD: the relevance of the geometry

Andrea Wulzer, Michele Redi, Diego Becciolini

We investigate the relevance of the metric and of the geometry in five-dimensional models of hadrons. Generically, the metric does not affect strongly the results and even flat space agrees reasonably well with the data. Nevertheless, we observe a preferen ...

A 3-D Audio-Visual Corpus of Affective Communication

Communication between humans deeply relies on the capability of expressing and recognizing feelings. For this reason, research on human-machine interaction needs to focus on the recognition and simulation of emotional states, prerequisite of which is the c ...
