Markets For Unverified Capability: Why Organizations Facing Real Adversarial Scrutiny Reject The Metrics Academic Ai-Security Research Relies On, Babar Khan Akhunzada Oct 2026

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 Oct 2026

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.

Twinning Behavior Of Molecule-Adapted Gaussian-Type Orbitals (Gtos) In Cyclo-Hydrocarbons, Tong-Hyok Cha, Gum-Chol Kim, Kwang-Jin Ri, Jin-Nam Kim, Yong-Su Pak

Turkish Journal of Chemistry

The saturated cyclo-hydrocarbons CnH2n (n = 3–7) were constructed by the iterative coupling of the structural unit groups (SUGs), specifically the SUG-CH2C2 fragment, which was previously established for molecular basis optimization. For the McLean–Chandler 6-311+G basis set, under the SUG perturbation, the outer (s′, p′) and diffuse (sʺ, pʺ) primitive Gaussian type orbitals for the core-atom C* of SUG-CH2C2 undergo an off-center spatial displacement into a twinning configuration. Specifically, the s-type twins (s′, sʺ) share identical Gaussian exponents and are symmetrically shifted toward the two neighboring carbon atoms, while the p-type twins (p′, pʺ) exhibit a matching configuration. Generally, this …

Samarium-Doped Ceria Catalysts For Boron-Aluminum Composite Propellants: Effect Of Synthesis Method, Di̇lara Güçtaş Gürel, Mehmet Ali̇ Faruk Öksüzömer

Turkish Journal of Chemistry

Solid propellants based on ammonium perchlorate (AP) are widely used in rocket and missile propulsion systems due to their high energy density and reliable combustion characteristics. Although aluminum (Al) is the conventional metal fuel in AP-based formulations, boron (B) has gained increasing attention as a partial or full substitute owing to its significantly higher volumetric energy density. However, the low combustion efficiency of boron particles remains a critical challenge, making the use of catalysts essential to enhance the thermal decomposition of AP and overall propellant-burning performance. In this study, samarium-doped ceria (SDC20) catalysts were synthesized by three different methods including …

Cobalt-Substituted Hydroxyapatite As A Potential Basis Of Biomaterials: Synthesis, Crystal-Chemistry Properties And Antibacterial Activity, Maria M. Vlasova, Ksenia S. Stasenko, Evgeny Bulanov

Turkish Journal of Chemistry

This paper presents the results of the synthesis of solid solutions of cobalt-substituted hydroxyapatite of the composition Ca10-xCox(PO4)6(OH)2 by the solid-phase and solution method. The formation of only the composition of Ca9.5Co0.5(PO4)6(OH)2 has been reliably established, whereas an increase in the cobalt content, as well as an increase in the temperature of synthesis and calcination of the samples prepared in solution, leads to the formation of stable mixtures of calcium and cobalt phosphates. The crystal structure has been refined for Ca9.5Co0.5(PO4)6(OH)2 (a = 9.4121(28) Å, c = 6.8762(20) Å, V = 527.54(35) Å3; R-Bragg = 2.455%) under the assumption of …

Proof Of The Wave Function Identity, A New Symmetry Constraint For The Three-Electron Quantum Dot In A Magnetic Field And Ad Hoc Generalization To Bound Many-Electron Systems, Marlina Slamet, Viraht Sahni

Publications and Research

We prove the Wave Function Identity (WFI), a newly discovered property of solutions to the two-dimensional Schrödinger–Pauli equation for the 𝑁 = 3 electron Coulombically interacting harmonically bound ‘artificial atom’ or quantum dot in a uniform magnetic field. The symmetry is comprised of an interchange of the spatial coordinates of two electrons whilst keeping their spin moments unchanged, followed by an inversion of all three electron coordinates. The proof is achieved by first deriving the general form of the exact correlated wave function in the high-electron-correlation Wigner regime and then proving the WFI employing this form for a ground and …

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.

Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith Oct 2026

Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith

International Journal of Speleology

Tourist activity is widely recognised as a source of cave microclimate disturbance, yet visitor-induced variability is difficult to distinguish from natural environmental fluctuations. The coronavirus pandemic created a natural experiment at Poole’s Cavern, United Kingdom, in which periods of complete closure could be compared with contrasting visitor access regimes. Two years of high resolution temperature records from six monitoring points were analysed. Harmonic regression and a state space model removed deterministic diurnal cycles and lower frequency temperature variability. The remaining residual variability differed systematically among visitor access regimes and between daytime and nighttime conditions. Spectral analysis of the residuals identified …

A Note On The Voronoi Congruences And The Residue Of The Fermat Quotient, Claire Levaillant Oct 2026

A Note On The Voronoi Congruences And The Residue Of The Fermat Quotient, Claire Levaillant

Communications on Number Theory and Combinatorial Theory

We prove a congruence on the residue of the Fermat quotient in base a which arises from a generalization of the Voronoi congruences and other congruences on sums and weighted sums of divided Bernoulli numbers. As an application in the base 2 case, we recover a congruence for the generalized harmonic number H2,(p-1)/2, a generalization originally due to Z-H. Sun of a classical congruence known for the harmonic number H(p-1)/2 as a special case of the Lerch formula. We find a sharpening of the Voronoi congruences that is different from the one of …

Representational Power As A Framework For Fairness With Applications To Redistricting, Jeffrey Barton Oct 2026

Representational Power As A Framework For Fairness With Applications To Redistricting, Jeffrey Barton

Mathematics Sciences: Faculty Publications

We introduce a framework for assessing fairness in electoral outcomes based on a new notion of representational power that determines a group's power as a combination of its size and how advantageously its voters are situated given the electoral rules. The framework is adaptable to a variety of contexts, and it produces intuitive results. When applied to redistricting, we call the measure the geographic representational baseline. The new measure is deterministic, accessible to non-experts, and relatively simple to calculate. The results generated by the new method are overall mutually reinforcing with those of a variety of ensemble methods for partisan …
