An analytical approach to the Rational Simplex Problem

, 2013
In 1973, J. Cheeger and J. Simons raised the following question that still remains open and is known as the Rational Simplex Problem: Given a geodesic simplex in the spherical 3-space so that all of its interior dihedral angles are rational multiples of $π$, is it true that its volume is a rational multiple of the volume of the 3-sphere?

Revisiting the Latin Vocabulary of Terminologia Histologica: II. Adjectives and Participles

Clinical Anatomy, EarlyView.
ABSTRACT Terminologia Histologica, the international standard nomenclature of human histology and cytology, contains 1093 Latin words that appear to be used as adjectives. Among these, we identified 56 (5%) with a variety of linguistic issues, including typographical or spelling errors, less favored spelling variants, and several unfortunate word ...

Linear Programming Optimization of Nutritional and Technological Properties in Wheat Bread Fortified With Taioba (Xanthosoma sagittifolium L.) Leaf Flour

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study applied linear programming to optimize taioba (Xanthosoma sagittifolium) leaf flour (TLF) incorporation in wheat bread, balancing nutritional enrichment and technological quality. Findings Breads containing 0%–15% TLF (flour basis) were produced and evaluated for composition, dough expansion, specific ...

Separable Simplex-structured Matrix Factorization: Robustness of Combinatorial Approaches

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
In this paper, we consider the following low-rank matrix approximation problem, referred to as separable simplex-structured matrix factorization: given an input matrix X, find W and H such that X ≈ WH where the columns of W are chosen among the columns of X and where the entries of each column of H are nonnegative and sum to at most one.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Membrane‐Permeable Nucleoside T‐1106 Diphosphate and Triphosphate Analogues as Antiviral Pronucleotides

Chemistry – A European Journal, EarlyView.
Favipiravir (T‐705) and the non‐fluorinated counterpart (T‐1106) are antiviral agents that inhibit the RNA‐dependent RNA polymerase (RdRp) of various RNA viruses. The antiviral efficacy of nucleoside analogues is strongly dependent on their intracellular activation by cellular kinases to produce their corresponding triphosphate metabolites (T‐705‐RTP ...

Asymptotic properties of cross‐classified sampling designs

Canadian Journal of Statistics, EarlyView.
Abstract We investigate the family of cross‐classified sampling designs across an arbitrary number of dimensions. We introduce a variance decomposition that enables the derivation of general asymptotic properties for these designs and the development of straightforward and asymptotically unbiased variance estimators.

A revision of the simplex species group of the cleptoparasitic bee genus Triepeolus Robertson, 1901 (Hymenoptera: Apidae)

European Journal of Taxonomy
Species of the cleptoparasitic bee genus Triepeolus Robertson, 1901 (Hymenoptera: Apidae: Nomadinae) of which the female has a trapezoidal or triangular pseudopygidial area with bright, reflective setae and a concave apical margin are revised.

Nonlinear permuted Granger causality

Canadian Journal of Statistics, EarlyView.
Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.

Upper bound limit analysis of coral reef limestone cavern roof stability incorporating a tension‐shear failure mechanism with tensile‐strength cut‐off

Deep Underground Science and Engineering, EarlyView.
For the roof of coral reef limestone caverns, a novel tension‐shear composite failure mechanism was developed. The most critical tensile crack model was identified using a hybrid optimization algorithm, and the stability of the cavern roof was analyzed accordingly.
