Constructing The Cyber Workforce Gap: Measurement And Its Consequences, Ryan Straight Oct 2026

Constructing The Cyber Workforce Gap: Measurement And Its Consequences, Ryan Straight

Journal of Cybersecurity Education, Research and Practice

Cyber workforce-gap figures steer federal strategy, industry advocacy, and the growth of educational programs. Rather than estimating the U.S. gap, this review examines how the estimates are made: through job-posting analytics, survey-based estimation, and federal accounting, each of which must assume its way from instrument to labor market. A census of this journal's complete run illustrates what those figures underwrite in one venue: of 176 items published across eleven years, 51 invoke a labor-market workforce claim, 46 treat it as settled fact, and only one, an editorial, interrogates it. Meanwhile, the producers and auditors of those figures have diverged. Between …

Markets For Unverified Capability: Why Organizations Facing Real Adversarial Scrutiny Reject The Metrics Academic Ai-Security Research Relies On, Babar Khan Akhunzada

Journal of Cybersecurity Education, Research and Practice

Governments, insurers, and defenders increasingly rely on published capability claims about AI cybersecurity agents to inform procurement, regulation, and risk assessment. Yet a striking pattern runs through the organizations with the most at stake: enterprises and technology companies deploying frontier AI agents against real production infrastructure consistently decline to publish the accuracy metrics that academic and vendor benchmarks compete to report. This paper investigates that pattern as an economic, organizational, and policy problem rather than a purely technical one. We audit eleven independently published AI cybersecurity benchmarks and deployments using a five-dimension integrity rubric and find that benchmarks relying on …

Computing The Greatest Common Divisor Of Binomial Coefficients C(Mn, Mk), Chai Wah Wu

Communications on Number Theory and Combinatorial Theory

The greatest common divisor (GCD) of C(2n,2k) for 1 ≤ k < n is known to be some power of 2 times the product of all odd primes p such that 2n = pi + pj. We complete the analysis of this GCD by showing that its 2-adic valuation is at most 1 and relates it to Mersenne primes. We also show how to efficiently compute GCD {C(mn,mk) : 1 ≤ k < n} when n and m satisfy certain conditions.

On A Remark Of De Gennes Concerning Three-Dimensional Polyelectrolytes, Shiquan Li, Carl Mueller Oct 2026

On A Remark Of De Gennes Concerning Three-Dimensional Polyelectrolytes, Shiquan Li, Carl Mueller

Journal of Stochastic Analysis

This work is inspired by a remark of de Gennes [3] about polyelectrolytes, which are charged polymers. A common model for a polymer is a self-avoiding or self-repelling random walk or Brownian motion. For polyelectrolytes, the repelling potential is the Coulomb potential arising from pairs of charged particles. We show that in the continuous case of a Brownian motion in three dimensions, the spread of the polymer, in particular the radius of gyration of a polyelectrolyte of length T grows linearly with T, up to logarithmic corrections.
