The occurrence of prime numbers revisited

open access: yesGECONTEC: Revista Internacional de Gestión del Conocimiento y la Tecnología, 2023
Based on an arithmetical and autocatalytic approach, the authors propose a solution for the occurrence of prime numbers. Exact arithmetical calculations are provided for: the closest prime to any given positive integer (or any number of bigger or ...

Association of elevated hs-CRP and multiple infarctions with outcomes of minor stroke or TIA: subgroup analysis of CHANCE randomised clinical trial

open access: yesStroke and Vascular Neurology, 2021
Background and purpose The relationship of high-sensitive C-reactive protein (hs-CRP) levels and infarction numbers with the prognosis of stroke is uncertain. This study evaluated the association of different hs-CRP levels and infarction numbers with the

Modelling the effect of habitat composition and roads on the occurrence and number of moose damage at multiple scales [PDF]

open access: yesSilva Fennica, 2019
We modelled the effect of habitat composition and roads on the number and occurrence of moose ( L.) damage in Ostrobothnia and Lapland using a zero-inflated count model. Models were developed for 1 km, 25 km and 100 km landscapes consisting of equilateral rectangular grid cells. Count models predict the number of damage, i.e.

Quantum Hall physics in rotating Bose-Einstein condensates [PDF]

open access: yes, 2008
The close theoretical analogy between the physics of rapidly rotating atomic Bose condensates and the quantum Hall effect (i.e., a two dimensional electron gas in a strong magnetic field) was first pointed out ten years ago.

Quantitative estimation of sampling uncertainties for mycotoxins in cereal shipments [PDF]

open access: yes, 2012
Many countries receive shipments of bulk cereals from primary producers. There is a volume of work that is ongoing that seeks to arrive at appropriate standards for the quality of the shipments and the means to assess the shipments as they are out-loaded.

Resolving Lexical Ambiguity in Tensor Regression Models of Meaning [PDF]

open access: yes, 2014
This paper provides a method for improving tensor-based compositional distributional models of meaning by the addition of an explicit disambiguation step prior to composition. In contrast with previous research where this hypothesis has been successfully
