Elentári: A $zsim3.3$ Proto-Supercluster in COSMOS

Kavli Affiliate: Michael McDonald | First 5 Authors: Ben Forrest, Brian C. Lemaux, Ekta Shah, Priti Staab, Ian McConachie | Summary: Motivated by spectroscopic confirmation of three overdense regions in the COSMOS field at $zsim3.35$, we analyze the uniquely deep multi-wavelength photometry and extensive spectroscopy available in the field to identify any further related structure. […]

Sub-second periodic radio oscillations in a microquasar

Kavli Affiliate: Feng Yuan | First 5 Authors: Pengfu Tian, Ping Zhang, Wei Wang, Pei Wang, Xiaohui Sun | Summary: Powerful relativistic jets are one of the ubiquitous features of accreting black holes in all scales. GRS 1915+105 is a well-known fast-spinning black-hole X-ray binary with a relativistic jet, termed as a “microquasar”, as indicated […]

How Does Diffusion Influence Pretrained Language Models on Out-of-Distribution Data?

Kavli Affiliate: Jing Wang | First 5 Authors: Huazheng Wang, Daixuan Cheng, Haifeng Sun, Jingyu Wang, Qi Qi | Summary: Transformer-based pretrained language models (PLMs) have achieved great success in modern NLP. An important advantage of PLMs is good out-of-distribution (OOD) robustness. Recently, diffusion models have attracted a lot of work to apply diffusion to […]

Reinforcement Learning for Sequential Decoding of Generalized LDPC Codes

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, David G. M. Mitchell, , , | Summary: In this work, we propose reinforcement learning (RL) for sequential decoding of moderate length generalized low-density parity-check (GLDPC) codes. Here, sequential decoding refers to scheduling all the generalized constraint nodes (GCNs) and single parity-check nodes (SPCNs) of […]

Flat-sky Angular Power Spectra Revisited

Kavli Affiliate: Anthony Challinor | First 5 Authors: Zucheng Gao, Zvonimir Vlah, Anthony Challinor, , | Summary: We revisit the flat-sky approximation for evaluating the angular power spectra of projected random fields by retaining information about the correlations along the line of sight. With broad, overlapping radial window functions, these line-of-sight correlations are suppressed and […]

A Novel Computationally Efficient Group Signature for Anonymous and Secure V2X Communications

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Liqun Chen, Mehrdad Dianati, Carsten Maple, Yan Yan | Summary: The use of vehicle-to-everything (V2X) communication is expected to significantly improve road safety and traffic management. We present an efficient protocol, called the AEE protocol, for protecting data authenticity and user privacy in V2X applications. […]

Non-Supersymmetric Heterotic Strings on a Circle

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Bernardo Fraiman, Mariana Graña, Héctor Parra De Freitas, Savdeep Sethi, | Summary: Motivated by a recent construction of non-supersymmetric $text{AdS}_3$, we revisit the $O(16)times O(16)$ heterotic string compactified on a torus. The string one-loop potential energy has interesting dependence on the classical moduli; extrema of this potential […]
