On the Power Map and Ring Commutativity [PDF]
Canadian Mathematical Bulletin, 1978 Let R denote an associative ring with 1, letnbe a positive integer, and letk= 1, 2, or 3. The ringRwill be called an (n, k)-ring if it satisfies the identitiesfor all integers m with n ≤ m ≤ n + k - 1. It was shown years ago by Herstein (See [2], [9], and [10]) that forn >1, any(n,l)-ring must have nil commutator idealC(R).Later Luh [12] proved that

Some Common Best Proximity Point Results in Neutrosophic Complete Metric Spaces
MathematicsIn this research article, we prove the existence and uniqueness of common best proximity points for a given class of discontinuous mappings. For that, we have introduced the notions of neutrosophic proximally compatible mappings, neutrosophic proximally ...

Commuting traces and commutativity preserving maps on triangular algebras
Journal of Algebra, 2004 The main result of the paper gives sufficient conditions under which every commuting trace of a bilinear map on a triangular algebra is of a standard form. These conditions are too technical to be stated here; let us just mention that they are fulfilled in the most important examples of triangular algebras.

Mapping Overlapping Commuting-to-Work Areas [PDF]
Journal of Maps, 2010 This article focuses on mapping and delineating commuting areas of work travel (commuting-towork area - CTWA). Traditional procedures for delimiting these areas assign each municipality to a single catchment area. Commuting distances and the complexity of commuter flows have increased steadily over the years. A classical method in transport planning is

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education
FEBS Open Bio, EarlyView.Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Solid Harmonic Wavelet Bispectrum for Image Analysis
Advanced Science, EarlyView.The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Advanced Science, EarlyView.Low‐level ambient benzene exposure is associated with increased risks of multiple brain disorders in urban adults. Genetic susceptibility modifies these associations, while plasma proteomics points to potential biological pathways linking benzene exposure to adverse brain health.
