On Azumaya Galois extensions and skew group rings
Two characterizations of an Azumaya Galois extension of a ring are given in terms of the Azumaya skew group ring of the Galois group over the extension and a Galois extension of a ring with a special Galois system is determined by the trace of the Galois

Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

ABSTRACT Declining natural resources, rising production costs, and diminishing returns from input‐intensive practices threaten the sustainability of smallholder rice systems in Bangladesh. Using a primal system approach and survey data from 1869 rice‐producing households, this study evaluates technical and allocative inefficiency across major agro ...

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

On characterizations of a center Galois extension
Let B be a ring with 1, C the center of B, G a finite automorphism group of B, and BG the set of elements in B fixed under each element in G. Then, it is shown that B is a center Galois extension of BG (that is, C is a Galois algebra over CG with ...

Non-Separable AF-Algebras [PDF]
We give two pathological phenomena for non-separable AF-algebras which do not occur for separable AF-algebras. One is that non-separable AF-algebras are not determined by their Bratteli diagrams, and the other is that there exists a non-separable AF-algebra which is prime but not primitive.

The Feasibility of Household Food Waste Reduction in Finland: Insights From Five Consumer Profiles
ABSTRACT We apply a household production framework to analyse how changes in cooking skills, waste‐abatement costs and wage rates influence the food waste behaviour of five consumer profiles in Finland. We find that achieving a given reduction in food waste through skill‐enhancing interventions induces larger behavioural adjustments than equivalent ...

DERIVATIONS OF TENSOR PRODUCT OF SIMPLE C*-ALGEBRAS [PDF]
In this paper we study the properties of derivations of A B, where A and B are simple separable C*-algebras, and A B is the C*-completion of A B with respect to a C*-norm Yon A B and we will characterize the derivations of A B in terms of the ...
