      Mathematics
      Algebraic Topology
      Category Theory
      Model structures for many different kinds of functor calculus can be obtained by applying a theorem of Bousfield to a suitable category of functors. In this paper, we give a general criterion for when model categories obtained via this appr...

      Enhanced Four-Body Decays of Charged Higgs Bosons into Off-Shell Pseudoscalar Higgs and W±W^\pmW± Boson Pairs in a Lepton-Specific 2-Higgs Doublet Model

      High Energy Physics - Phenomenology
      We study the time-honoured decay H±→AW±H^\pm\to A W^\pmH±→AW± but for the first time, we do so for the case of both AAA and W±W^\pmW± being off-shell, therefore computing a 1→41\to 41→4 body decay. We show that the corresponding decay rate not only extends...

      Deep learning algorithms often are trained and deployed on different datasets. Any systematic difference between the training and a test dataset may degrade the algorithm performance--what is known as the domain shift problem. This issue is...

      We report on the development of an advanced ultracold dysprosium apparatus, which incorporates a cold atom microscope (CAM) with a design resolution of a quarter micrometer. The CAM and the cooling and trapping regions are within the same v...

      We consider gas of massless fermions at certain temperature T and acceleration a. We find a second order phase transition at temperature T approaching the Unruh temperature TU. The implications for hadronization of the quark-gluon plasma pr...

      This research assesses the performance of two deep learning models, SAM and U-Net, for detecting cracks in concrete structures. The results indicate that each model has its own strengths and limitations for detecting different types of crac...

      Collective behavior of spins, frustration-induced strong quantum fluctuations, and subtle interplay between competing degrees of freedom in quantum materials can lead to correlated quantum states with exotic excitations that are essential i...

      Some counterexamples in surface homology

      Algebraic Topology
      We present four counterexamples in surface homology. The first example shows that even if the loops inducing a homology basis intersect each other at most once, they still may separate the surface into two parts. The other three examples sh...

      Chiral and non-chiral swift mode conversion near an exception point with dynamic adiabaticity engineering

      Applied Physics
      The eigenvalue of a non-Hermitian Hamiltonian often forms a self-intersecting Riemann surface, leading to a unique mode conversion phenomenon when the Hamiltonian evolves along certain loop paths around an exceptional point (EP). However, t...
