7 resultsTime-Resolved GRB Polarization with POLAR and GBM
J. Michael Burgess, M. Kole, F. Berlato +5
The paper presents a Bayesian analysis framework that jointly fits spectral and polarization data from the POLAR and GBM instruments for GRB 170114A, finding time‑varying polarizat…
Optimizing Pinning Control of Complex Dynamical Networks Based on Spectral Properties of Grounded Laplacian Matrices
Hui Liu, Xuanhong Xu, Jun-An Lu +2
The paper proposes an algebraic graph‑theoretic condition to optimize pinning control in complex dynamical networks by maximizing the smallest eigenvalue of the grounded Laplacian…
The essential spectrum of canonical systems
Christian Remling, Kyle Scarbrough
The paper investigates the lower bound of the essential spectrum for canonical systems of the form Ju' = -zHu, extending previous characterizations of purely discrete spectra by ap…
Approximating Pointwise Products of Quasimodes
Mei Ling Jin
The paper derives bounds for approximating products of Laplace‑Beltrami quasimodes on compact Riemannian manifolds by low‑dimensional vector spaces, using bilinear quasimode estima…
HISS, a new tool for H I stacking: application to NIBLES spectra
J. Healy, S-L. Blyth, E. Elson +5
The paper introduces HISS, a Python package for stacking H I emission and absorption spectra, and uses it on NIBLES SDSS galaxies to study how H I content relates to galaxy colour…
Polynomials on cyclic monotone elements with applications to random matrices with discrete spectrum
Octavio Arizmendi, Adrian Celestino
The paper extends formulas for the spectra of polynomials in cyclic monotone elements and applies these results to study random matrices that have a discrete spectrum.
The de Rham-Hodge analysis and modeling of biomolecules
Rundong Zhao, Menglun Wang, Yiying Tong +1
The paper introduces de Rham‑Hodge theory as a unified mathematical framework for analyzing the geometry, topology, flexibility, and natural modes of biological macromolecules, and…
