Introduction: Phase images generated using gradient echo techniques at high field strengths show excellent contrast related to the different magnetic susceptibilities of various brain tissues [1,2]. However, extraction of accurate anatomical information from these images is made difficult by the non-local relationship between the field perturbation and the associated susceptibility distribution...

High incidence of colon cancer worldwide indicates the importance of studying genetic alterations that lead to its carcinogenesis. Two polymorphisms in H-ras gene, hexanucleotide tandem repeats in the first intron and SNP 81T>C in the first exon, that might be connected with susceptibility to cancer have been described. The aim of our study was to investigate these loci in Croatian population a...

a.sacharovi, which is one of the main malaria vectors of the palearchic region, is resistant to ddt in greece (1949), lebanon (1954), turkey (1959), syria and the u.s.s.r. (1972).the first record of a. sacharovi resistance to ddt in iran was given in 1959 from the kazeroon area, followed by izeh (1969) and meshkin-shahr (1970).this study (1973) urgently advises speedy measures to eliminate the ...

Heterogeneity in host susceptibility is a key determinant of infectious disease dynamics but is rarely accounted for in assessment of disease control measures. Understanding how susceptibility is distributed in populations, and how control measures change this distribution, is integral to predicting the course of epidemics with and without interventions. Using multiple experimental and modeling...

We develop a consistent technique for the calculation of real photon emission in hard exclusive processes, which is based on the background field formalism and allows a convenient separation of hard electromagnetic and soft hadronic components of the photon. The latter ones are related to matrix-elements of light-cone operators in the electromagnetic background field and can be parametrized in ...

While all investigators report wide individual differences in susceptibility to hypnosis, the form of the distribution is a matter of some uncertainty. Some years ago Hull' concluded that "susceptibility to hypnotic suggestion is fairly evenly distributed over the range from no susceptibility whatever to the most profound susceptibility." In a more recent review Weitzenhoffer2has shown a summar...

There are two types of three-dimensional (3D) magnetic inversion methods based on the classification of the inversion result, one is the inversion approach that determines a 3D susceptibility distribution that produces a given magnetic anomaly, and the other is to inverse the source distribution in a purely probabilistic sense, in which the inversion results are equivalent physical parameters b...

literature and culture are two inseparable issues. when we talk about the culture, the literature can also appear unconsciously, because the culture is composed of thoughts, feelings and emotions and the styles and personal ways of society, which as a general rule, can appear in terms of principles and respectful rules. the literature on the other hand, discloses and transmits these concepts to...

The variable generalised stochastic epidemic (VGSE) model which allows for variability in both the susceptibility and infectivity of individuals is analysed. A very different epidemic model which exhibits variable susceptibility and infectivity is the random graph epidemic model. A suitable coupling of the two epidemic models is derived, which enables us to show that, whilst the epidemics are v...

A key assumption underlying fMRI analysis in the general linear model is that the underlying distribution of BOLD Susceptibility is gaussian. Analysis of several common data sets and experimental paradigms shows that the underlying distribution for the BOLD signal is non-Gaussian. Further identification shows that the distribution is probably Gamma and implications for hemodynamic modeling are ...
