Reductionism and the Universal Calculus [PDF]
, 2016 In the seminal essay, "On the unreasonable effectiveness of mathematics in the physical sciences," physicist Eugene Wigner poses a fundamental philosophical question concerning the relationship between a physical system and our capacity to model its ...

Biases towards the zero residue class for quadratic forms in arithmetic progressions
Mathematika, Volume 72, Issue 2, April 2026.Abstract We prove a bias towards the zero residue class in the distribution of the integers represented by binary quadratic forms. In most cases, we prove that the bias comes from a secondary term in an associated asymptotic expansion. This is unlike Chebyshev's bias, which exists somewhere at the level of O(x1/2+ε)$O(x^{1/2+\varepsilon })$.

Zwischen Ordnung und Verwirrung: Missverständnisse in der Nomenklatur von Kohlenstoffmaterialien
Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.Trotz der vielfältigen Einsatzmöglichkeiten von Kohlenstoffmaterialien führen uneinheitliche Terminologie und unzureichende Charakterisierung – insbesondere im Hinblick auf die Ordnung der zugrunde liegenden Graphenen – häufig zu Fehlinterpretationen. Der Artikel klärt Begriffe wie Graphit, graphitischer Kohlenstoff, nicht‐graphitischer Kohlenstoff und

Between Order and Confusion: Clearing up Structural Misconceptions in Carbon Materials Nomenclature
Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.Despite the versatile use of carbon materials, inconsistent terminology and inadequate characterization – especially regarding graphene structures based on sp2‐hybridized carbon atoms – often cause confusion. This perspective clarifies terms like graphite, graphitic carbon, non‐graphitic carbon, and amorphous carbon by aligning IUPAC definitions with X‐

A Symbolic Algorithm for Checking the Identifiability of a Time-Series Model
InformationSeveral authors have attempted to compute the asymptotic Fisher information matrix for a univariate or multivariate time-series model to check for its identifiability. This has the form of a contour integral of a matrix of rational functions.

Regarding on The Novel Forms of the (3+1) - Dimensional Kadomstev-Petviashvili Equation
ITM Web of Conferences, 2017 This article, we have applied the Bernoulli Sub-Equation method to the (3+1)-Dimensional Kademstev-Petviashvili equation. We have obtained some new analytical solutions such as exponential function and rational solutions by using this technique.
