Multicore fiber optic imaging reveals that astrocyte calcium activity in the cerebral cortex is modulated by internal motivational state

Posted by klaurent Hopkins

Kavli Affiliate: Jin Kang, Dwight Bergles | Authors: Yung-Tian A. Gau, Eric Hsu, Jaepyeong Cha, Rebecca W. Pak, Loren L. Looger, Jin U. Kang and Dwight E. Bergles | Summary: Astrocytes are a direct target of neuromodulators and can influence neuronal activity on broad spatial and temporal scales through their close proximity to synapses. However, […]

Inverse problems for Dirac operators with a constant delay less than half of the interval

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Chuan-Fu Yang | Summary: In this work, we consider Dirac-type operators with a constant delay less than half of the interval and not less than two fifths of the interval. For our considered Dirac-type operators, an inverse spectral problem is studied. Specifically, reconstruction of two […]

Solving Cosine Similarity Underestimation between High Frequency Words by L2 Norm Discounting

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Saeth Wannasuphoprasit, Yi Zhou, Danushka Bollegala | Summary: Cosine similarity between two words, computed using their contextualised token embeddings obtained from masked language models (MLMs) such as BERT has shown to underestimate the actual similarity between those words (Zhou et al., 2022). This similarity underestimation problem is […]

The emergence of human gastrulation upon in vitro attachment

Posted by klaurent Rockefeller

Kavli Affiliate: Ali H. Brivanlou | Authors: Riccardo De Santis, Eleni Rice, Gist Croft, Min Yang, Edwin A. Rosado-Olivieri and Ali H. Brivanlou | Summary: While studied extensively in model systems, human gastrulation remains obscure. This process starts upon blastocyst implantation into the uterine wall, which is assumed to occur after 14 days post-fertilization. The […]
