Single-test evaluation of directional elastic properties of anisotropic structured materials

Posted by klaurent April 18, 2023May 1, 2023Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Jagannadh Boddapati, Moritz Flaschel, Siddhant Kumar, Laura De Lorenzis, Chiara Daraio | Summary: When the elastic properties of structured materials become direction-dependent, the number of their descriptors increases. For example, in two-dimensions, the anisotropic behavior of materials is described by up to 6 independent elastic stiffness parameters, […]

TTIDA: Controllable Generative Data Augmentation via Text-to-Text and Text-to-Image Models

Posted by klaurent April 18, 2023May 1, 2023Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yuwei Yin, Jean Kaddour, Xiang Zhang, Yixin Nie, Zhenguang Liu | Summary: Data augmentation has been established as an efficacious approach to supplement useful information for low-resource datasets. Traditional augmentation techniques such as noise injection and image transformations have been widely used. In addition, generative data augmentation […]

Nucleus accumbens and dorsal medial striatal dopamine and neural activity are essential for action sequence performance

Posted by klaurent April 17, 2023May 1, 2023Hopkins

Kavli Affiliate: Patricia Janak | Authors: Kurt M Fraser, Bridget J Chen and Patricia H Janak | Summary: Separable striatal circuits have unique functions in Pavlovian and instrumental behaviors but how these roles relate to performance of sequences of actions with and without associated cues is less clear. Here we tested whether dopamine release and […]

JADES: Insights on the low-mass end of the mass–metallicity–star-formation rate relation at $3 < z < 10$ from deep JWST/NIRSpec spectroscopy

Posted by klaurent April 17, 2023Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Roberto Maiolino, Emma Curtis-Lake, Jacopo Chevallard, Stefano Carniani | Summary: We analyse the gas-phase metallicity properties of a sample of low stellar mass (log M*/M_sun <= 9) galaxies at 3 < z < 10, observed with JWST/NIRSpec as part of the JADES programme in its […]

Phase Stability of Hexagonal/cubic Boron Nitride Nanocomposites

Posted by klaurent April 17, 2023Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Abhijit Biswas, Rui Xu, Joyce Christiansen-Salameh, Eugene Jeong, Gustavo A. Alvarez | Summary: Boron nitride (BN) is an exceptional material and among its polymorphs, two-dimensional (2D) hexagonal and three-dimensional (3D) cubic BN (h-BN and c-BN) phases are most common. The phase stability regimes of these BN phases […]

Extended thermodynamics of the bumblebee black holes

Posted by klaurent April 17, 2023Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Zhan-Feng Mai, Rui Xu, Dicong Liang, Lijing Shao, | Summary: As a vector-tensor theory including nonminimal coupling between the Ricci tensor and a vector field, the bumblebee gravity is a potential theory to test Lorentz symmetry violation. Recently, a new class of numerical spherical black holes in […]
