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 […]

Towards the biogeography of butyrate-producing bacteria

Posted by klaurent UCSF

Kavli Affiliate: Robert Edwards | Authors: Joel E Brame, Craig Liddicoat, Catherine A Abbott, Robert A Edwards, Jake M Robinson, Nicolas E Gauthier and Martin F Breed | Summary: Butyrate-producing bacteria are found in many ecosystems and organisms, including humans, and are vital to ecosystem functionality and human health. These bacteria ferment organic matter, producing […]

Excitonic and deep-level emission from N- and Al-polar homoepitaxial AlN grown by molecular beam epitaxy

Posted by dbos Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Jashan Singhal, Jimy Encomendero, Naomi Pieczulewski, Celesta Chang | Summary: Using low-temperature cathodoluminescence spectroscopy, we study the properties of N- and Al-polar AlN layers grown by molecular beam epitaxy on bulk AlN{0001}. Compared to the bulk AlN substrate, layers of both polarities feature a […]
