Shaping Mathematics into Stories by means of Propp’s Narratemes [PDF]
, 2017 For a few decades now, scholars have tried to make mathematics education more meaningful and motivating by using narratives. However, there still remains a gap between the theory of narratives and classroom practice.

From Kepler’s conjecture and fcc lattice to modelling of crowding in living matter [PDF]
, 2013 Up to now, sphere packing has been investigated without any reference to living matter. This study focuses on the void space (VS) of sphere packing to mimic the extracellular spaces of living tissues.

Journal of Applied Polymer Science, EarlyView.This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment
Advanced Physics Research, EarlyView.Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Investigating abelian categories in univalent type theory
, 2021 In 1976 the first computer checked proof was made to prove the four color theorem. This raised questions about how these computations should be interpreted to create a formal proof, as well as the validity of the proof given.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, EarlyView.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Corporate Environmental Responsibility and Cost of Equity Capital: A Meta‐Analytical Review
Business Strategy and the Environment, EarlyView.ABSTRACT Despite extensive research on the relationship between corporate environmental responsibility (CER) and cost of equity capital (COEC), empirical evidence remains inconsistent. This study addresses these inconsistencies through a comprehensive meta‐analysis of 1139 effect sizes from 75 studies.

Business Strategy and the Environment, EarlyView.ABSTRACT Firms' strategic decision‐making relies not only on their own information but also on that disclosed by supply chain partners. While research recognizes buyers' importance in green innovation, the impact of their information disclosure remains underdeveloped. Drawing on the extended resource‐based view, this study investigates the joint effect
