Ecologists have recently used integral projection models (IPMs) to study fish and other animals which continue grow throughout their lives. Such cannot shrink, since they bony skeletons; a mathematical consequence of this is that the kernel operator T unbounded, not compact. To our knowledge, all theoretical work done on IPMs has assumed compact, in particular bounded kernel. A priori, it uncle...
The purpose of this paper is to give a necessary and sufficient condition for the existence non-existence global solutions following semilinear parabolic equations \[ u_{t}=\Delta u+\psi(t)f(u),\,\,\mbox{ in }\Omega\times (0,t^{*}), \] under Dirichlet boundary on bounded domain. In fact, has remained as an open problem few decades, even case $f(u)=u^{p}$. As matter we prove: \begin{aligned} &\m...
The MicroPsi agent architecture describes the interaction of emotion, motivation and cognition of situated agents based on the Psi theory of Dietrich Dörner. This theory touches on a number of questions, particularly about perception, representation and bounded rationality, in very interesting ways, but being formulated within psychology, has had relatively little impact on the discussion of ag...
Given a nonempty finite word $v$, let $PL(v)$ be the palindromic length of $v$; it means minimal number palindromes whose concatenation is equal to $v$. Let $v^R$ denote reversal or infinite $y$, $Fac(y)$ set all factors $y$ and $maxPL(y)=\max\{PL(t)\mid t\in Fac(y)\}$. $x$ an non-ultimately periodic with $maxPL(x)=k<\infty$ $u\in Fac(x)$ primitive factor such that $u^5$ recurrent in $x$. $\Psi...
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
The ability to assess the importance of secretin in various physiological processes is limited by the lack of specific potent antagonists. Recently, reduced peptide bond (psi) analogues of bombesin or substance P in which the -CONH- bond is replaced by -CH2NH- are reported to be receptor antagonists. To attempt to develop a new class of secretin receptor antagonists, we have adopted a similar s...
PSI-G is an 11 kDa subunit of PSI in photosynthetic eukaryotes. Arabidopsis thaliana plants devoid of PSI-G have a decreased PSI content and an increased activity of NADP(+) photoreduction in vitro but otherwise no obvious phenotype. To investigate the biochemical basis for the increased activity, the kinetic parameters of the reaction between PSI and plastocyanin were determined. PSI-G clearly...
معمولا پایدار سازهای سیستم قدرت برای حل مسائل ناپایداری سیستم های قدرت مورد استفاده قرار می-گیرند. بدین منظور معمولاً برای طراحی pss، آنالیز مقادیر ویژه بر اساس متغیرهای فضای حالت مورد استفاده قرار می گیرد. به هر حال، روشهای سنتی همچنان بر اساس حالت های قطعی سیستم هستند. برای در نظر گرفتن محدوده گسترده تغییرات شرایط بهره برداری، گزارش ارائه شده روش احتمالاتی مدونی را برای آنالیز مقادیر ویژه و طر...

BACKGROUND Although the Pneumonia Severity Index (PSI) has been extensively validated, little is known of the impact of its routine use as an aid to site-of-treatment decisions for patients with pneumonia who present to emergency departments (EDs). METHODS A prospective, observational, controlled cohort study of patients with pneumonia was conducted in 8 EDs that used the PSI (PSI-user EDs) a...
