The JCMT Transient Survey: Single Epoch Transients and Variability of Faint Sources

Posted by klaurent Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Doug Johnstone, Bhavana Lalchand, Steve Mairs, Hsien Shang, Wen Ping Chen | Summary: Short-duration flares at millimeter wavelengths provide unique insights into the strongest magnetic reconnection events in stellar coronae, and combine with longer-term variability to introduce complications to next-generation cosmology surveys. We analyze 5.5 years […]

Valley-coherent quantum anomalous Hall state in AB-stacked MoTe2/WSe2 bilayers

Posted by klaurent Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Bowen Shen, Shengwei Jiang, Tingxin Li, Lizhong Li | Summary: Moir’e materials provide fertile ground for the correlated and topological quantum phenomena. Among them, the quantum anomalous Hall (QAH) effect, in which the Hall resistance is quantized even under zero magnetic field, is a direct […]

From Prediction to Action: Dissociable Roles of Ventral Tegmental Area and Substantia Nigra Dopamine Neurons in Instrumental Reinforcement

Posted by klaurent Hopkins

Kavli Affiliate: Patricia Janak | Authors: Kurt Michael Fraser, Heather J Pribut, Patricia H Janak and Ronald Keiflin | Summary: Abstract Reward-seeking requires the coordination of motor programs to achieve goals. Midbrain dopamine neurons are critical for reinforcement and their activation is sufficient for learning about cues, actions, and outcomes. Here we examine in detail […]

A General Lattice and Basis Formalism Enabling Efficient and Discretized Exploration of Crystallographic Phase Space

Posted by klaurent Berkeley

Kavli Affiliate: Kristin Persson | First 5 Authors: David Mrdjenovich, Kristin Persson, , , | Summary: Three-dimensional lattices are fundamental to solid-state physics. The description of a lattice with an atomic basis constitutes the necessary information to predict solid phase properties and evolution. Here, we present a new algorithm for systematically exploring crystallographic phase space. […]

Understanding the effects of charge diffusion in next-generation soft X-ray imagers

Posted by klaurent MIT

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Eric D. Miller, Gregory Y. Prigozhin, Beverly J. LaMarr, Marshall W. Bautz, Richard F. Foster | Summary: To take advantage of high-resolution optics sensitive to a broad energy range, future X-ray imaging instruments will require thick detectors with small pixels. This pixel aspect ratio affects spectral […]

TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf

Posted by klaurent MIT

Kavli Affiliate: George Ricker | First 5 Authors: Faith Hawthorn, Daniel Bayliss, Thomas G. Wilson, Andrea Bonfanti, Vardan Adibekyan | Summary: We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright ($T = 8.5$ mag), high proper motion ($sim,200$ mas yr$^{-1}$), […]

A Hybrid Model of Classification and Generation for Spatial Relation Extraction

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang Peifeng Li, Qiaoming Zhu, , , | Summary: Extracting spatial relations from texts is a fundamental task for natural language understanding and previous studies only regard it as a classification task, ignoring those spatial relations with null roles due to their poor information. To address […]

Spectral extremal graphs for disjoint cliques

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Zhenyu Ni, Jing Wang, Liying Kang, , | Summary: The $kK_{r+1}$ is the union of $k$ disjoint copies of $(r+1)$-clique. Moon [Canad. J. Math. 20 (1968) 95–102] and Simonovits [Theory of Graphs (Proc. colloq., Tihany, 1996)] independently showed that if $n$ is sufficiently large, then $K_{k-1}vee T_{n-k+1,r}$ […]
