Pupillary dynamics reflect the impact of temporal expectation on detection strategy - data
<p>This repository contains data from work that investigated how humans can extract hidden temporal cues from the occurrences of probabilistic targets and utilize them to inform target detection in a complex acoustic stream, using a combination of behavioral measures and pupillometry. It accompanies the article entitled: " <strong>Pupillary dynamics reflect the impact of temporal expectation on detection strategy</strong>" from the same authors. It contains:<br> - preprocessed pupil data for all subjects<br> - similarly matched behavior data for all subjects<br> - custom code for both behavioral and pupil analysis</p>

Mouse spontaneous behavior reflects individual variation rather than estrous state
<p>Repository containing datasets obtained for Levy et al. 2023, available online here: https://doi.org/10.1016/j.cub.2023.02.035</p> <p>Github link to related analysis code: <a href="https://github.com/dattalab/spontaneous-behavior-reflects-individuality-not-estrous">https://github.com/dattalab/spontaneous-behavior-reflects-individuality-not-estrous</a></p> <p><strong>Abstract</strong></p> <p>Behavior is shaped by both the internal state of an animal and its individual behavioral biases. Rhythmic variation in gonadal hormones during the estrous cycle is a defining feature of female internal state, one that regulates many aspects of sociosexual behavior. However, it remains unclear whether estrous state influences spontaneous behavior, and if so how these effects might relate to individual behavioral variation. Here we address this question by longitudinally characterizing the open field behavior of female mice across different phases of the estrous cycle, using unsupervised machine learning to decompose spontaneous behavior into its constituent elements1-4. We find that each female mouse exhibits a characteristic pattern of exploration that uniquely identifies it as an individual across many experimental sessions; in contrast, estrous state only negligibly impacts behavior, despite its known effects on neural circuits that regulate action selection and movement. Like female mice, male mice exhibit individual specific patterns of behavior in the open field; however, the exploratory behavior of males is significantly more variable than that expressed by females both within and across individuals. These findings suggest an underlying functional stability to the circuits that support exploration in female mice, reveal a surprising degree of specificity in individual behavior, and provide empirical support for the inclusion of both sexes in experiments querying spontaneous behaviors.</p> <p><strong>Behavioral DataFrames:</strong> holds the behavioral syllable data used for the analysis described in the manuscript:</p> <ul> <li>mean_df_female / scalar_df_female - main female dataset</li> <li>mean_df_male / scalar_df_male - main male dataset</li> <li>mean_df_female_control / mean_df_male_control - datasets for male/female control experiment presented in Fig S3.</li> </ul> <p><strong>Model files:</strong></p> <p>Additional MoSeq model files used for generating FigS2A and FigS2H. </p>

Supercurrent, Multiple Andreev Reflections and Shapiro Steps in InAs Nanosheet Josephson Junctions
<p>This file contains the raw data and processing codes of the paper 'Supercurrent, Multiple Andreev Reflections and Shapiro Steps in InAs Nanosheet Josephson Junctions'.</p> <p> High-quality free-standing InAs nanosheets are emerging layered semiconductor materials with potentials in designing planar Josephson junction devices for novel physics studies due to their unique properties including strong spin-orbit couplings, large Landé g-factors and the two dimensional nature. Here, we report an experimental study of proximity induced superconductivity in planar Josephson junction devices made from free-standing InAs nanosheets. The nanosheets are grown by molecular beam epitaxy and the Josephson junction devices are fabricated by directly contacting the nanosheets with superconductor Al electrodes. The fabricated devices are explored by low-temperature carrier transport measurements. The measurements show that the devices exhibit a gate-tunable supercurrent, multiple Andreev reflections, and a good quality superconductor-semiconductor interface. The superconducting characteristics of the Josephson junctions are investigated at different magnetic fields and temperatures, and are analyzed based on the Bardeen-Cooper-Schrieffer (BCS) theory. The measurements of ac Josephson effect are also conducted under microwave radiations with different radiation powers and frequencies, and integer Shapiro steps are observed. Our work demonstrates that InAs nanosheet based hybrid devices are desired systems for investigating forefront physics, such as the two-dimensional topological superconductivity.</p>

"The main message is that sustainability would help" – Reflections on takeaway messages of climate change data visualizations.
<p>As part of a larger project investigating expert opinions on public climate change communication and the role of data visualizations1, we conducted semi-structured interviews with 17 experts in the fields of climate change, science communication, or data visualization. We also interviewed six members of the general public with no professional background in either of these areas, who we refer to as lay participants. In the following, lay participants are identified as L-1 to L-6 and expert participants as E-1 to E-17.</p> <p>We used two example visualizations from online news sources (if preferred, translated to German) as a discussion basis and asked participants about the main takeaway message the visualization author wanted to convey. Example visualization 1 was also shown to 17 experts, resulting in a total of 23 formulated takeaway messages. Example visualization 2 was shown to all six lay participants and to seven experts, resulting in a total of 13 messages. For both example visualizations and an overall count of 36 formulated takeaway messages for thematic analysis, we have observed variations in the included contents and the length/abstraction of messages, as well as in the sensemaking process itself among the two participant groups, but also between lay and expert participants. This document provides an overview of those 36 takeaway messages formulated by the study participants.</p>
