Vector alignment in matrix Lie groups
Congzhou M Sha
Two observers of the same physical system may differ in gauge by a group element acting on their common vector representations, and recovering that element from finite, noisy paire…
A putative, computationally stable structure of homotrimeric BP180/collagen XVII
Congzhou M Sha
Background: BP180, also known as collagen XVII and BPAG2 (bullous pemphigoid antigen 2), is a 180-kDa transmembrane protein within the hemidesmosomal plaque complex, and which is k…
Optimal alignment of Lorentz orientation and generalization to matrix Lie groups
Congzhou M Sha
There exist elegant methods of aligning point clouds in . Unfortunately, these methods fail to generalize to the case of Minkowski space, as we will show. Instead, we…
tParton: Implementation of next-to-leading order evolution of transversity parton distribution functions
Congzhou M Sha, Bailing Ma
We provide code to solve the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equations for the nucleon transversity parton distribution functions (PDFs), which encode…
On the continuity of flows
Congzhou M Sha
Flow matching has emerged as a powerful framework for generative modeling through continuous normalizing flows. We investigate a potential topological constraint: when the prior di…
Mitigating collusion in Gold Humanism Honor Society nominations
Congzhou M Sha
An anecdotally common complaint regarding induction into the Gold Humanism Honor Society is the bias toward close friends during the initial nomination process. In this work, we nu…
