Wide-gap CdTe Strip Detectors for High-Resolution Imaging in Hard X-rays

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Shunsaku Nagasawa, Takahiro Minami, Shin Watanabe, Tadayuki Takahashi, | Summary: We propose a new strip configuration for CdTe X-ray detectors, named "Wide-gap CdTe strip detector", in which the gap between adjacent strips is much wider than the width of each strip. It has been known that the […]

DREAM: Efficient Dataset Distillation by Representative Matching

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yanqing Liu, Jianyang Gu, Kai Wang, Zheng Zhu, Wei Jiang | Summary: Dataset distillation aims to synthesize small datasets with little information loss from original large-scale ones for reducing storage and training costs. Recent state-of-the-art methods mainly constrain the sample synthesis process by matching synthetic images and […]

Limits to the strain engineering of layered square-planar nickelate thin films

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Dan Ferenc Segedin, Berit H. Goodge, Grace A. Pan, Qi Song, Harrison LaBollita | Summary: The layered square-planar nickelates, Nd$_{n+1}$Ni$_{n}$O$_{2n+2}$, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in Nd$_{6}$Ni$_{5}$O$_{12}$ thin films. Here, we investigate […]

Investigation of Cryogenic Current-Voltage Anomalies in SiGe HBTs: Role of Base-Emitter Junction Inhomogeneities

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Jacob Kooi, Kieran A. Cleary, Austin J. Minnich | Summary: The anomalous current-voltage characteristics of cryogenic SiGe heterojunction bipolar transistors (HBTs) have been a topic of investigation for many years. Proposed explanations include quasiballistic transport of electrons across the base or […]

Investigation of Cryogenic Current-Voltage Anomalies in SiGe HBTs: Role of Base-Emitter Junction Inhomogeneities

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Justin H. Chen, Jacob Kooi, Kieran A. Cleary | Summary: The deviations of cryogenic collector current-voltage characteristics of SiGe heterojunction bipolar transistors (HBTs) from ideal drift-diffusion theory have been a topic of investigation for many years. Recent work indicates that direct […]

A recently quenched galaxy 700 million years after the Big Bang

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Roberto Maiolino, Joris Witstok, Lester Sandles | Summary: Local and low-redshift ($z$<$3$) galaxies are known to broadly follow a bimodal distribution: actively star forming galaxies with relatively stable star-formation rates, and passive systems. These two populations are connected by galaxies in relatively […]

Robust Field-level Likelihood-free Inference with Galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: NatalĂ­ S. M. de Santi, Helen Shao, Francisco Villaescusa-Navarro, L. Raul Abramo, Romain Teyssier | Summary: We train graph neural networks to perform field-level likelihood-free inference using galaxy catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project. Our models are rotational, translational, and permutation invariant and do […]
