Categories without structures [PDF]
arXiv, 2009 The popular view according to which Category theory provides a support for Mathematical Structuralism is erroneous. Category-theoretic foundations of mathematics require a different philosophy of mathematics. While structural mathematics studies invariant forms (Awodey) categorical mathematics studies covariant transformations which, generally, don t ...

Moderate deviations for the determinant of Wigner matrices
, 2013 We establish a moderate deviations principle (MDP) for the log-determinant $\log | \det (M_n) |$ of a Wigner matrix $M_n$ matching four moments with either the GUE or GOE ensemble.

Advanced Functional Materials, EarlyView.Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

Pao-Lu Hsu (Xu, Bao-lu): The Grandparent of Probability and Statistics in China
, 2012 The years 1910-1911 are auspicious years in Chinese mathematics with the births of Pao-Lu Hsu, Luo-Keng Hua and Shiing-Shen Chern. These three began the development of modern mathematics in China: Hsu in probability and statistics, Hua in number theory ...

Parasitology, 1992 The paper describes a mathematical model for canine leishmaniasis and presents formulae which can be used to estimate the basic reproduction number,R0. The primary concern has been to devise methods of estimation which make best use of those data most easily obtained by fieldwork, e.g. surveys of prevalence in dog (by age) and sandfly populations.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Mathematical Models in Schema Theory [PDF]
arXiv, 2005 In this paper, a mathematical schema theory is developed. This theory has three roots: brain theory schemas, grid automata, and block-shemas. In Section 2 of this paper, elements of the theory of grid automata necessary for the mathematical schema theory are presented.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Numbers and functions in Hilbert's finitism [PDF]
, 1998 David Hilbert's finitistic standpoint is a conception of elementary number theory designed to answer the intuitionist doubts regarding the security and certainty of mathematics.
