Deep Learning Improves Parameter Estimation in Reinforcement Learning Models

Kavli Affiliate: Marcelo Mattar | Authors: Hua-Dong Xiong, Li Ji-An, Marcelo G Mattar and Robert C Wilson | Summary: Cognitive modeling in psychology and neuroscience provides a formal approach to formulate and test hypotheses of cognitive processes. Such models rely on cognitive parameters that are intended to represent interpretable and identifiable psychological constructs. However, accurately […]

Spectral disruption of inter-hemispheric resting-state BOLD coherence at vasomotor frequency (~0.1 Hz) links vascular dysfunction to functional connectivity loss in carotid artery stenosis

Kavli Affiliate: David Kleinfeld | Authors: Sangcheon Choi, Gabriel Hoffmann, Sebastian Schneider, Stephan Kaczmarz, David Kleinfeld, Xin Yu, Christian Sorg and Christine Preibisch | Summary: Vasomotor dynamics at the infra-slow frequencies (~0.1 Hz), driven by synchronized oscillation of smooth muscle cells in vessel walls, play an important role in regulating cerebral perfusion and constitute a […]

Accept-reject decision-making revealed via a quantitative and ethological study of C. elegans foraging

Kavli Affiliate: Sreekanth Chalasani | Authors: Jessica A Haley, Tianyi Chen, Mikio Aoi and Sreekanth H Chalasani | Summary: Decision-making is a ubiquitous component of animal behavior that is often studied in the context of foraging. Foragers make a series of decisions while locating food (food search), choosing between food types (diet or patch choice), […]

Architecture, Activation, and Conformational Plasticity in the GluA4 AMPA Receptor

Kavli Affiliate: Richard Huganir | Authors: William Dylan Hale, Richard L. Huganir and Edward C Twomey | Summary: AMPA-subtype glutamate receptors (AMPARs), composed of subunits GluA1-4, mediate fast, excitatory synaptic transmission in the brain. After glutamate binding, AMPAR ion channels exhibit multiple subconductance states that tune neuronal responses to glutamate. GluA4 is the rarest subunit […]

Curriculum Learning for Biological Sequence Prediction: The Case of De Novo Peptide Sequencing

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Jiaqi Wei, Zijie Qiu, Sheng Xu, Nanqing Dong | Summary: Peptide sequencing-the process of identifying amino acid sequences from mass spectrometry data-is a fundamental task in proteomics. Non-Autoregressive Transformers (NATs) have proven highly effective for this task, outperforming traditional methods. Unlike autoregressive models, which generate […]

Excitations and dynamical structure factor of $J_1-J_2$ spin-$3/2$ and spin-$5/2$ Heisenberg spin chains

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Aman Sharma, Mithilesh Nayak, Natalia Chepiga, Frédéric Mila, | Summary: We study the dynamical structure factor of the frustrated spin-$3/2$ $J_1$-$J_2$ Heisenberg chains, with particular focus on the partially dimerized phase that emerges between two Kosterlitz-Thouless transitions. Using a valence bond solid ansatz corroborated by density matrix […]

Diagnosing 2D symmetry protected topological states via mixed state anomaly

Kavli Affiliate: Shenghan Jiang | First 5 Authors: Chao Xu, Yunlong Zang, Yixin Ma, Yingfei Gu, Shenghan Jiang | Summary: Symmetry-protected topological (SPT) phases are short-range entangled quantum states characterized by anomalous edge behavior, a manifestation of the bulk-boundary correspondence for topological phases. Moreover, the Li-Haldane conjecture posits that the entanglement spectrum exhibits the same […]

Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Shaul Hanany, Scott Cray, Samuel Dietterich, Jan Dusing, Calvin Firth | Summary: We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response […]
