Unusual critical currents in quasi-one-dimensional superconducting aluminum two-width structures in a magnetic field

V. I. Kuznetsov, O. V. Trofimov · 2026

We measured unusual critical currents as functions of temperature in the zero field and as functions of a magnetic field perpendicular to the substrate surface at a given temperature close to the crit…

The Lifetime Cardiac-Cycle Invariant in Endothermic Vertebrates: A 230-Species Comparative Dataset, Statistical Validation, and Explicit Falsifiability Criteria

Mesfin Taye · 2026

A pygmy shrew (\textit{Suncus etruscus}, ${\approx}2$\,g) sustains a resting heart rate near $1{,}000$\,beats\,min$^{-1}$ and dies within two years; an African elephant (${\approx}4{,}000$\,kg) beats …

Extension of Excess Demand Ascending Auction to Multi-Demand Model by Discrete Convex Analysis Approach

Kazuo Murota, Akiyoshi Shioura · 2026

We consider the problem of finding the (unique) minimal Walrasian equilibrium price in multi-item, multi-unit auction models: there are multiple indivisible items for sale, with several units of each …

Multifaceted Hero Developers and Bug-Fixing Outcomes Across Severity

Amit Kumar, Mahen Gandhi, Meher Bhardwaj, Hrishikesh Ethari, Sonali Agarwal · 2026

Open-source projects often rely on a small group of highly active contributors known as hero developers. Prior work shows that hero developers are common in many OSS and enterprise projects, yet who q…

Differential Subgroup Discovery: Characterizing Where Two Populations Differ, and Why

Sascha Xu, Jilles Vreeken · 2026

We study the problem of understanding where two populations differ within a feature space, which we formalize in the concept of a differential subgroup: a subset of individuals from both populations w…

On the Difference Between Pulsar Radio Emission Beams from the Two Poles

Xiancong Wu, Hongguang Wang, Hao Tong, Rui Luo, Pengfei Wang, Chengbing Lyu, Hai Lei · 2026

The long-standing assumption of symmetric radio emission beams from the two magnetic poles of pulsars is challenged by observational evidence of asymmetry and underfill. Direct testing of this symmetr…

Observation of Universal Spectral Moments and the Dynamic Dispersive-to-Proliferative Transition

Jia-Xin Zhong, Chang Shu, Nan Cheng, Jee Woo Kim, Kai Zhang, Kai Sun, Yun Jing · 2026

In non-Hermitian systems, spectra can be maximally boundary-sensitive, yet bulk physics need not be. Here we experimentally show that spectral moments provide boundary-robust bulk observables in finit…

Pauli equation in spaces of constant curvature and extended Nikiforov-Uvarov method

Abdaljalel E. Alizzi, Zurab K. Silagadze · 2026

We apply the extended Nikiforov-Uvarov method to the non-relativistic limit of the Dirac equation with a Coulomb potential in spaces of constant curvature. In this case, the radial equation reduces to…
