Towards massless sector of tensionless strings on AdS5

open access: yesPhysics Letters B, 2020
A Higher Spin Gravity in five dimensions is constructed. It was shown recently that constructing formally consistent classical equations of motion of higher spin gravities is equivalent to finding a certain deformation of a given higher spin algebra.

SIM‐CaliRam: A workflow combining simulation‐informed references and biomass‐augmented features for in‐line Raman calibration of Saccharomyces cerevisiae

open access: yesBiotechnology Progress, EarlyView.
SIM‐CaliRam combines simulation‐informed references and biomass‐augmented features for in‐line Raman calibration under sparse labels and biomass‐induced spectral confounding. Run‐wise calibration and validation enable prediction of biomass, glucose, ammonium, and phosphate on an unseen S. cerevisiae fed‐batch fermentation.

On the Directly and Subdirectly Irreducible Many-Sorted Algebras

open access: yesDemonstratio Mathematica, 2015
A theorem of single-sorted universal algebra asserts that every finite algebra can be represented as a product of a finite family of finite directly irreducible algebras.

Total blow-ups of modules and universal flatifications

open access: yes, 2017
We study the projective spectrum of the Rees algebra of a module, and characterize it by a universal property. As applications, we give descriptions of universal flatifications of modules and of birational projective morphisms.

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

The life and work of Ernest Sydney Keeping

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...

Universal Algebra in Topoi

open access: yes, 1973
This thesis represents an attempt to marry two distinct directions of research in Modern Algebra. On the one hand we have the theory of topoi which has been undergoing vigorous development within the last three years.

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Post-Hopf algebroids, post-Lie-Rinehart algebras and geometric numerical integration

open access: yesForum of Mathematics, Sigma
In this paper, we introduce the notion of post-Hopf algebroids, generalizing the pre-Hopf algebroids introduced in [8] in the study of exotic aromatic S-series. We construct action post-Hopf algebroids through actions of post-Hopf algebras.
