Field-Angle Dependence of Phonon Thermal Hall Effect in Na2X2TeO6 (X = Co, Zn)
Jian Yan, Hikaru Takeda, Haruka Iwahata +5
The mechanism behind thermal Hall effects by phonons, which are observed in various materials, is not clarified despite the dominant contribution as heat carriers. Theoretically, m…
FOSSIL: Regret-minimizing weighting for robust learning under imbalance and small data
J. Cha, J. Lee, J. Cho +1
Imbalanced and small data regimes are pervasive in domains such as rare disease imaging, genomics, and disaster response, where labeled samples are scarce and naive augmentation of…
Competing Interactions and the Effects of Uniaxial Out-of-plane Perturbations in the Honeycomb Antiferromagnet NaCoTeO
J. Arneth, R. Kalaivanan, R. Sankar +2
Despite exhibiting magnetic long-range order below , the honeycomb cobaltate NaCoTeO is predicted to enter a Kitaev spin liquid state w…
Multi-k magnetic structure and large anomalous Hall effect in candidate magnetic Weyl semimetal NdAlGe
C. Dhital, R. L. Dally, R. Ruvalcaba +15
The magnetic structure, magnetoresistance, and Hall effect of non-centrosymmetric magnetic semimetal NdAlGe are investigated revealing an unusual magnetic state and anomalous trans…
Underwater Acoustic Communication Channel Modeling using Reservoir Computing
Oluwaseyi Onasami, Ming Feng, Hao Xu +2
Underwater acoustic (UWA) communications have been widely used but greatly impaired due to the complicated nature of the underwater environment. In order to improve UWA communicati…
Calibrated Bagging Deep Learning for Image Semantic Segmentation: A Case Study on COVID-19 Chest X-ray Image
Lucy Nwosu, Xiangfang Li, Lijun Qian +2
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). Imaging tests such as chest X-ray (CXR) and computed tomography (CT) can pr…
