A three-level relief chain including a number of suppliers in fixed locations, candidate distribution centers and affected areas at certain points are considered. A mixed integer nonlinear programming model is proposed for open transportation location routing problem by considering split delivery of demand. To solve a realistic problem, foregoing parameters are considered as fuzzy in our propos...

There is great scientific and popular interest in understanding the genetic history of populations in the Americas. We wish to understand when different regions of the continent were inhabited, where settlers came from, and how current inhabitants relate genetically to earlier populations. Recent studies unraveled parts of the genetic history of the continent using genotyping arrays and unipare...

We construct the Plancherel measure corresponding to the Bessel model on the split special orthogonal group of odd degree ≥ 5 and the Whittaker model on a connected split reductive group in general. As an application we prove the inversion formula which expresses the related integral transform in terms of the Satake transform.

In this paper a new model is proposed for Gate Oxide Short defects based on a non-split MOS transistor. Because the MOS is not split, this model allows to simulate minimum transistors in realistic digital circuits. The construction of the model is presented in details using a comprehensive and didactic approach. It is demonstrated that the electrical behavior of the proposed model perfectly mat...

The common ancestors of today’s humans and today’s chimpanzees presumably lived several million years ago. Then, due to genetic mutations and/or changes in the environment, the population split into the ancestors of humans and the ancestors of chimpanzees. Such a separation of one species into two is called “speciation”. It is easily explained if the two populations live in separate environment...

For an admixed population, an important question is how much genetic contribution comes from each parental population. Several methods have been developed to estimate such admixture proportions, using data on genetic markers sampled from parental and admixed populations. In this study, I propose a likelihood method to estimate jointly the admixture proportions, the genetic drift that occurred t...

This study presents a method to model population densities by using image texture statistics of semi-variance. In a case study of the City of Austin, Texas, we first selected sample census blocks of the same land use to build population models by land use. Regression analyses were conducted to infer the relationship between block population densities and image texture statistics of the semivari...

In many of the special sciences, mathematical models are used to provide information about specified target systems. For instance, population models are used in ecology to make predictions about the abundance of real populations of particular organisms. The status of mathematical models, though, is unclear and their use is hotly contested by some practitioners. A common objection levelled again...

The aim of this population based neuroepidemiological study was to establish the real incidence rates of acute cerebrovascular disease (CVD): stroke and transient ischemic attack (TIA) in the Republic of Croatia. Multicentric study included 89 501 persons of all ages in four regional centres in Croatia: Zagreb, Osijek + Slavonski Brod, Rijeka and Split. The following incidence rates of stroke, ...

Population abundances of both Acarina (mites) and Collembola (springtails) were examined for continuous corn grown under no-till and conventional management practices on a clay loam, an Orthic Humic Gleysol (Typic Haplaquoll) near Ottawa, Ont., Canada (Lat. 458 220 N; Long. 758 430 W). For each tillage practice, samples for soil faunal extraction and soil attribute characterization were taken p...
