Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia
Insect Conservation and Diversity, EarlyView.Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

Two New Equilateral Triangles Associated with a Triangle
Scientific Inquiry and Review, 2019 In this short paper, we study two new equilateral triangles associated with an arbitrary triangle and further generalizations.

Journal of Fish Biology, EarlyView.Abstract The northeastern Atlantic Forest of Brazil harbours a remarkable diversity of species of Trichomycteridae, many of which remain poorly understood. This study describes a new species of Ituglanis, endemic to the Ribeirão São Roque, a stream tributary of Rio Piabanha, an affluent of Rio Colônia basin, Bahia State, Brazil.

Is Word Order Asymmetry Mathematically Expressible?
Biolinguistics, 2013 The computational procedure for human natural language (CHL) shows an asymmetry in unmarked orders for S, O, and V. Following Lyle Jenkins, it is speculated that the asymmetry is expressible as a group-theoretical factor (included in Chomsky’s third ...

An enumeration of equilateral triangle dissections
Discrete Applied Mathematics, 2010 We enumerate all dissections of an equilateral triangle into smaller equilateral triangles up to size 20, where each triangle has integer side lengths. A perfect dissection has no two triangles of the same side, counting up- and down-oriented triangles as different. We computationally prove W. T.

Erythrocyte ‘Feierzeit’ reaction: Novel filamentous and vesicular response to n‐butyl acetate
Journal of Microscopy, EarlyView.Abstract Human erythrocytes (red blood cells; RBCs) undergo spontaneous disassembly after several hours of exposure to n‐butyl acetate (nBA). Images of the morphological changes were captured in time‐lapse sequences using differential interference contrast (DIC) light microscopy.

Exploring 2D Geometric Shape Classification Using AI‐Driven Feature Tables in Mathematics
School Science and Mathematics, EarlyView.ABSTRACT This study explored the effectiveness of an AI‐integrated instructional task designed to enhance preservice teachers' understanding of the features and hierarchical relationships of 2D geometric shapes. Originally developed and tested in online K‐12 professional development settings, this intervention was adapted for in‐person preservice ...

Tilings of an Isosceles Triangle
, 2019 An N-tiling of triangle ABC by triangle T is a way of writing ABC as a union of N trianglescongruent to T, overlapping only at their boundaries. The triangle T is the "tile". The tile may or may not be similar to ABC.

Application of Group‐Theoretical Approaches in Structural Natural Frequency Analyses
International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.ABSTRACT Group theory has profoundly advanced physics and chemistry in systems with symmetries. Yet its use in structural engineering applications has not yet been fully explored beyond the aesthetics of symmetric designs. This work addresses two significant gaps that have limited the broader adoption of group‐theoretic methods in structural vibration ...
