to study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (cad), a study has been designed to compare this feature between patients having stable angina (sa) or unstable angina (ua) who underwent coronary angiography in tehran heart institute. study objectives were detection of the angina producing artery (ap a) and its morphologic lesion type, de...
background: significant elevation of cardiac biomarkers after percutaneous coronary intervention (pci) is associated with increased mortality. however, clinical importance of lesser degrees of cardiac enzyme elevation has not been well understood. multiple factors might have an etiologic role, and the incidence of myonecrosis has not changed dramatically despite pharmacological and technologica...
in a semiarid region of central iran, effects of parent materials, physiography and landscape position, land use, andmanagement practices on association of organic carbon with secondary (aggregates) particles and aggregate stability canhave important consequences in terms of carbon sequestration and budgeting, deciding on the proper land use strategy andsuitable soil conservation practices. it ...

آنالیز فرآیندهای ایستا در قلمرو(دامنه طیفی) بر توزیع های طیفی بنا شده است . اما برای فرآیندهای غیرایستای هارمونیک ساز(harmonizable) ، زوج (f, ) که f یک اندازه برداری (vector measure) و یک اندازه بورل می باشد ، به عنوان مشخصه های طیفی ارائه می شود. در این پایان نامه یک روش طبیعی برای ساختن نمایش طیفی ارائه می شود که این روش برای فرآیندهای مرتبه دوم (second order processes) و فرآیندهای پایدار (st...
It is well-known that not all instances of the stable roommates problem admit a stable matching. Here we establish the first nontrivial upper bound on the limiting behavior of P,,, the probability that a random roommates instance of size n has a stable matching, namely, limn-P,, I el% (=0.8244. . .).
We consider the two-sided stable matching setting in which there may be uncertainty about the agents’ preferences due to limited information or communication. We consider three models of uncertainty: (1) lottery model — in which for each agent, there is a probability distribution over linear preferences, (2) compact indifference model — for each agent, a weak preference order is specified and e...
Dynamics of lead metabolism were studied by replacement of a portion of the dietary lead with stable isotope tracers, and maintaining subjects on controlled diets for about 6 months. Results for one subject have been previously reported. Preliminary data are now available for a second subject. Although the data on the two subjects are basically similar, there are also significant differences. T...
A stable matching for an instance of the stable marriages problem or the stable roommates problem is bistable if it is also a stable matching when the ordering of the input preference lists is reversed. For the stable marriages problem, it is shown that the bistable matchings are a sublattice of the distributive lattice of stable matchings. In addition, the Gale Shapley algorithm is modified to...
In this note we present some sufficient conditions for the uniqueness of a stable matching in the Gale-Shapley marriage classical model of even size. We also state the result on the existence of exactly two stable matchings in the marriage problem of odd size with the same conditions.
