A few weeks ago, GDC'25 (https://globaldigitalcollaboration.org/agenda?day=2025-07-02) was hosted in Geneva, and we got together to discuss many different aspects of digital identity. I was very happy that consensus seems to converge on unlinkability as a non-negotiable…

A converse to Cartan's Theorem B: The extension property for real analytic and Nash sets
In 1957 Cartan proved his celebrated Theorem B and deduced that if $Ω\subset{\mathbb R}^n$ is an open set and $X$ is a coherent real analytic subset of $Ω$, then $X$ has the analytic extension property, that is, each real analytic function on $X$ extends to a real analytic function on $Ω$. The converse implication in its full generality remains unproven. In the literature only special cases of non-coherent real analytic sets $X\subsetΩ$ without the extension property appear, some of them du…

Identifier Name Similarities: An Exploratory Study
Identifier names, which comprise a significant portion of the codebase, are the cornerstone of effective program comprehension. However, research has shown that poorly chosen names can significantly increase cognitive load and hinder collaboration. Even names that appear readable in isolation may lead to misunderstandings in contexts when they closely resemble other names in either structure or functionality. In this exploratory study, we present our preliminary findings on the occurrence of id…

Nonexistence of Consecutive Powerful Triplets Around Cubes with Prime-Square Factors
The Erdős-Mollin-Walsh conjecture, asserting the nonexistence of three consecutive powerful integers, remains a celebrated open problem in number theory. A natural line of inquiry, following recent work by Chan (2025), is to investigate potential counterexamples centered around perfect cubes, which are themselves powerful. This paper establishes a new non-existence result for a family of such integer triplets with distinct structural constraints, combining techniques from modular arithmetic, $…

Further aspects of Supersymmetric Virasoro Minimal Strings
A supersymmetric version of the Virasoro minimal string was defined some time ago using random matrix model techniques. Several of the special properties of the matrix model that were noted (accessible fully non-perturbatively) underlie features shared by both 0A and 0B versions of the theory. This paper develops the formalism much further, including showing how the 0A and 0B choices familiar in continuum approaches have a direct analogue in terms of building solutions of the appropriate string…

A Novel Coded Computing Approach for Distributed Multi-Task Learning
Distributed multi-task learning (DMTL) effectively improves model generalization performance through the collaborative training of multiple related models. However, in large-scale learning scenarios, communication bottlenecks severely limit practical system performance. In this paper, we investigate the communication bottleneck within a typical DMTL system that employs non-linear global updates. This system involves distributed workers, assisted by a central server, who collaboratively learn di…

Precise Measurement of the $\Lambda$ Electric Dipole Moment through the Entangled Strange Baryon-Antibaryon System

Precise Measurement of the $Λ$ Electric Dipole Moment through the Entangled Strange Baryon-Antibaryon System
The dominance of matter over antimatter in the universe has consistently driven the pursuit of new physics beyond the Standard Model that violates charge-parity symmetry. Unlike the well-constrained electrons and neutrons, strange baryons (hyperons) remain a largely unexplored territory, in which interactions between hyperons and particles from new physics could induce a non-trivial electric dipole moment (EDM). However, direct measurements of hyperon EDMs through spin precession are highly cha…

Integrating Pair Programming as a Work Practice
Context: Pair programming (PP) is more relevant than ever. As modern systems grow in complexity, knowledge sharing and collaboration across teams have become essential. However, despite well-documented benefits of PP, its adoption remains inconsistent across software teams. Objective: This study aims to understand the factors that facilitate or hinder team members' adoption as well as lasting engagement in PP. Method: We have conducted an exploratory single-case study in a mature agile company …
