Salmonella control in poultry flocks and its public health impact. [PDF]

EFSA J, 2019
Abstract An increase in confirmed human salmonellosis cases in the EU after 2014 triggered investigation of contributory factors and control options in poultry production. Reconsideration of the five current target serovars for breeding hens showed that there is justification for retaining Salmonella Enteritidis, Salmonella Typhimurium (including ...

Coevolution of Lexical Meaning and Pragmatic Use. [PDF]

Cogn Sci, 2018
Abstract According to standard linguistic theory, the meaning of an utterance is the product of conventional semantic meaning and general pragmatic rules on language use. We investigate how such a division of labor between semantics and pragmatics could evolve under general processes of selection and learning.

A new De Vylder type approximation of the ruin probability in infinite time [PDF]

, 2003
In this paper we introduce a generalization of the De Vylder approximation. Our idea is to approximate the ruin probability with the one for a different process with gamma claims, matching first four moments. We compare the two approximations studying mixture of exponentials and lognormal claims.

Affected by and affecting forest fires in Sweden and Spain: A critical feminist analysis of vulnerability to fire

Sociologia Ruralis, Volume 63, Issue 3, Page 729-750, July 2023., 2023
Abstract Usually, vulnerability is equated to weakness and resistance to strength. Drawing on a feminist critique of this conceptualisation, this article aims to discuss how vulnerability to forest fires and local action are mutually and contradictorily related. I analyse the ways in which people in two rural communities surrounded by tree monocultures

The Bühlmann–Straub Estimation of Claim Means in Random B‐F Reserve Model

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
In the B‐F reserve model, it is a very critical step to estimate the claim means of the accident year. However, the traditional method uses the prior estimators of the claim means based on the personal experience of actuaries or historical data. This method inevitably carries the subjectivity of the actuary himself.

Cell nuclei detection using globally optimal active contours with shape prior [PDF]

, 2012
Cell nuclei detection in fluorescent microscopic images is an important and time consuming task for a wide range of biological applications. Blur, clutter, bleed through and partial occlusion of nuclei make this a challenging task for automated detection

Leaf segmentation and tracking using probabilistic parametric active contours [PDF]

, 2011
Active contours or snakes are widely used for segmentation and tracking. These techniques require the minimization of an energy function, which is generally a linear combination of a data fit term and a regularization term.

The mitochondrial NAD+ transporter (NDT1) plays important roles in cellular NAD+ homeostasis in Arabidopsis thaliana

The Plant Journal, Volume 100, Issue 3, Page 487-504, November 2019., 2019
Summary Nicotinamide adenine dinucleotide (NAD+) is an essential coenzyme required for all living organisms. In eukaryotic cells, the final step of NAD+ biosynthesis is exclusively cytosolic. Hence, NAD+ must be imported into organelles to support their metabolic functions.

The Pólya‐Aeppli process and ruin problems

International Journal of Stochastic Analysis, Volume 2004, Issue 3, Page 221-234, 2004., 2004
The Pólya‐Aeppli process as a generalization of the homogeneous Poisson process is defined. We consider the risk model in which the counting process is the Pólya‐Aeppli process. It is called a Pólya‐Aeppli risk model. The problem of finding the ruin probability and the Cramér‐Lundberg approximation is studied.

Teorija propasti i de Vylderova aproksimacija [PDF]

, 2014
U ovom radu smo promatrali Cramér-Lundbergov model u teoriji rizika. On se sastoji od pretpostavke da je proces isplata šteta složen Poissonov. U prvom poglavlju smo definirali složeni Poissonov proces, te smo dali još neke definicije i izvode koje ...
