In model selection, usually a 'best" predictor is chosen from collection {A(., s)} of predictors where j(., s) is the minimum least squares predictor in a collection U, of predictors. Here s is a complexity parameter; that is, the smaller s, the lower dimensional/smoother the models in U. If L is the data used to derive the sequence {j(.,s)}, the procedure is called unstable if a small change i...

we consider the semilinear elliptic boundary value problem  = ∈∂ω− δ = ∈ωu x xu x f u x x( ) 0;( ) λ ( ( ));where λ > 0 is a parameter, ω is a bounded region in rn with a smooth boundary, and f is asmooth function. we prove, under some additional conditions, the existence of a positive solution for λlarge. we prove that our solution u for λ large is such that = →∞∈ω|| u ||: sup| u(x) |xas λ ...

introduction: unstable angina as a clinical condition includes a major group of patients manifested with acute coronary syndrome. misdiagnosis of this clinical syndrome causes myocardial infarction (mi) and death. conventional and advanced forms of treatment are used with the aim of rapid stabilization of unstable angina. although infusion of glucose - insulin - potassium (gik) solution has had...

BACKGROUND The delayed release of serum cardiac markers such as creatine kinase isoenzyme MB and equivocal early electrocardiographic changes have hampered a diagnosis of acute myocardial infarction (AMI) in the early phase after its onset. Therefore, a reliable serum biochemical marker for the diagnosis of AMI in the very early phase is desirable. METHODS AND RESULTS Serum samples were colle...

this paper presents a simplified approach to estimate the resultant force, which should be provided by a retention system, for the equilibrium of unstable slopes. the results were obtained with a developed algorithm, based on limit equilibrium analyses, that assumes a two-part wedge failure mechanism. design charts to obtain equivalent earth pressure coefficients are presented. based on the res...

The appropriate generalization of the isotropic impurity Anderson model for va-lence fluctuations between two magnetic multiplets l n and l n+1 is solved in the strong-coupling limit of Wilson's renormalization group for l ≤ 3. Except in the extreme case of j − j coupling, the ground state is degenerate, the impurity magnetic moment is very small and is overscreened by the conduction electrons....

objectives: the main purpose of this study was to determine the interactive role of physical activity and personality traits inpsychosocial development of elders. methods & materials: this research was a casual comparative with 300 elders (150 active and 150 non-actives) with 60-85 years old from tehran selected as statistical sample on available bases. all subjects completed psychosocial devel...

conclusions: patent coronaries of ua/nstemi patients have a trend to higher tfcs compared to normal values. presence of significant coronary lesions in these patients significantly increases tfc. objectives: the present study is aimed to measure the tfc in the coronary arteries of ua/nstemi patients to find abnormalities in diseased or patent vessels and compare with the normal values. patients...

background & objectives: regional planning requires identification of the development status of regions relative to each other. one of the indicators of development is health indicator that describes utilization of health services in the society. the purpose of this study is to analyze health indicators status in ardabil province and prioritize them for future planning. methods: based on practi...

The stability of topological solitary waves and pulses in one-dimensional nonlinear Klein-Gordon systems is revisited. linearized equation describing small deviations around the static solution leads to a Sturm-Liouville problem, which solved systematic way for $-l\,(l+1)\,\sech^2(x)$-potential, showing orthogonality completeness relations fulfilled by set its solutions all values $l\in\mathbb{...
