False paradoxes: the first faces of the infinity concept in the context of mathematical science

ACTIO: Docência em Ciências, 2019
The paper presents the results of a theoretical research that studied the infinity and the relation of this mathematical concept with the false paradoxes given by Zeno, contrary to atomistic conception of time and space. More specifically, we studied the

Enhancing Super‐Resolution Spatial Transcriptomics Data by Transfer Learning

Advanced Science, EarlyView.
SpotZoomer employs a transfer‐learning‐based strategy to enhance the resolution of Visium data by leveraging available high‐resolution priors. The resulting super‐resolved maps enable sharper delineation of cell boundaries and more precise inference of cell–cell communication patterns that would otherwise remain obscured at native resolution.

Simulation of Infinitely Divisible Random Fields [PDF]

Communications in Statistics - Simulation and Computation, 2012
Two methods to approximate infinitely divisible random fields are presented. The methods are based on approximating the kernel function in the spectral representation of such fields, leading to numerical integration of the respective integrals. Error bounds for the approximation error are derived and the approximations are used to simulate certain ...

Effective methods for increasing levels of political self‐efficacy for girls and disadvantaged students in England

British Educational Research Journal, EarlyView.
Abstract This study addresses the gap in rigorous evaluation of inclusive Citizenship Education methods in reducing gender and socioeconomic inequalities in political self‐efficacy. This article tests the effectiveness of two pedagogical approaches: counter‐narratives and think‐pair‐share.

Food‐solicitation displays in nestling birds: still begging for answers

Biological Reviews, EarlyView.
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.

Lasso for hierarchical polynomial models

Canadian Journal of Statistics, EarlyView.
Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

Climate Vulnerability and Sovereign ESG Performance: The Conditioning Roles of Adaptation Innovation, Institutional Quality and Robot Adoption

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The intensification of physical climate risk presents a critical question for global sustainability governance: does exposure to climate hazards strengthen or weaken a country's environmental, social and governance (ESG) performance? This study investigates the relationship between climate vulnerability and country‐level ESG performance across

On the Stationary Measure for Markov Branching Processes

Mathematics
A previous study determined criteria ensuring that a probability distribution supported in positive integers is the limiting conditional law of a subcritical Markov branching process.

Mixed Steiner Triple Systems With Shortest Length

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A mixed Steiner triple system is a 3‐GDD which is viewed as a code with minimum Hamming distance 3. These codes are the minimum weight codewords of a 1‐perfect code over a mixed alphabet, when the related codes exist, and provide the connection between 3‐GDDs and coding theory.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...
