Tell machine learning potentials what they are needed for: Simulation-oriented training exemplified for glycine

Posted by dbos Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Fuchun Ge, Ran Wang, Chen Qu, Peikun Zheng, Apurba Nandi | Summary: Machine learning potentials (MLPs) are widely applied as an efficient alternative way to represent potential energy surface (PES) in many chemical simulations, e.g., geometry optimizations, frequency calculations, molecular dynamics, and Monte Carlo computations. However, there […]

Electrically controlled nonvolatile switching of single-atom magnetism in a Dy@C84 single-molecule transistor

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Wangqiang Shen, Yuan Shui, Jun Chen, Huaiqiang Wang | Summary: Single-atom magnetism switching is a key technique towards the ultimate data storage density of computer hard disks and has been conceptually realized by leveraging the spin bistability of a magnetic atom under a scanning tunnelling […]

Subvolume method for SU(2) Yang-Mills theory at finite temperature: topological charge distributions

Posted by dbos Tokyo

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Norikazu Yamada, Masahito Yamazaki, Ryuichiro Kitano, , | Summary: We apply the previously-developed sub-volume method to study the $theta$-dependence of the four-dimensional SU(2) Yang-Mills theory at finite temperature. We calculate the first two coefficients, the topological susceptibility $chi$ and the fourth cumulant $b_2$, in the $theta$-expansion of […]

Sparse-Coding Variational Auto-Encoders

Posted by dbos Hopkins

Kavli Affiliate: Adam S. Charles | Authors: Victor Geadah, G. Barello, Adam Charles and Jonathan Pillow | Summary: The sparse coding model posits that the visual system has evolved to efficiently code natural stimuli using a sparse set of features from an overcomplete dictionary. The original sparse coding model suffered from two key limitations, however: […]

Pavlovian cue-evoked alcohol seeking is disrupted by ventral pallidal inhibition

Posted by dbos Hopkins

Kavli Affiliate: Damon Clark | Authors: Patricia Janak | Summary: Cues paired with alcohol can be potent drivers of craving, alcohol-seeking, consumption, and relapse. While the ventral pallidum is implicated in appetitive and consummatory responses across several reward classes and types of behaviors, its role in behavioral responses to Pavlovian alcohol cues has not previously […]

Adaptation to visual sparsity enhances responses to infrequent stimuli

Posted by dbos Yale

Kavli Affiliate: Damon Clark | Authors: Tong Gou, Catherine A Matulis and Damon A Clark | Summary: Sensory systems adapt their response properties to the statistics of their inputs. For instance, visual systems adapt to low-order statistics like mean and variance to encode the stimulus efficiently or to facilitate specific downstream computations. However, it remains […]

Neurexin drives C. elegans avoidance behavior independently of its post-synaptic binding partner Neuroligin

Posted by dbos UCSD / Salk

Kavli Affiliate: Sreekanth Chalasani | Authors: Caroline S Muirhead, Kirthi C Reddy, Sophia Guerra, Michael Rieger, Michael P Hart, Jagan Srinivasan and Sreekanth H Chalasani | Summary: Neurexins and their canonical binding partners, neuroligins, are localized to neuronal pre-, and post-synapses, respectively, but less is known about their role in driving behaviors. Here, we use […]
