in this paper we consider several generalizations of the skew t-normal distribution, and some of their properties. also, we represent several theorems for constructing each generalized skew t-normal distribution. next, we illustrate the application of the proposed distribution studying the ratio of two heavy metals, nickel and vanadium, associated with crude oil in shadgan wetland in the south-...

Clifford theory of finite groups is generalized to association schemes. It shows a relation between irreducible complex characters of a scheme and a strongly normal closed subset of the scheme. The restriction of an irreducible character of a scheme to a strongly normal closed subset coniatns conjugate characters with same multiplicities. Moreover some strong relations are obtained.

An autarky is a partial assignment to the variables of a Boolean CNF formula that satisfies every clause containing an assigned variable. For an unsatisfiable formula, an autarky provides information about those clauses that are essentially independent from the infeasibility; clauses satisfied by an autarky are not contained in any minimal unsatisfiable subset (MUS) or minimal correction subset...

We established a normal reference range for peripheral blood lymphocyte subsets in a multiracial adult population by using single-platform flow cytometry. Further analysis of our cohort showed that the CD8+-cell counts decrease with age, there is a gender difference in NK cell percentages and counts, and there are significant differences in the CD3+-, CD4+-, and CD19+-cell counts between Indian...

Lymphocyte subset reference values used to monitor infectious diseases, including HIV/AIDS, tuberculosis, malaria, or other immunological disorders in healthy children in Cameroon, are lacking. Values for Caucasian cohorts are already being utilized for clinical decisions but could be inappropriate for African populations. We report here the immunological profile for children aged from birth th...

Estimation of T-lymphocyte subsets continues to be an important aspect for monitoring HIV disease progression and response to antiretroviral therapy. Most of the diagnostic laboratories often rely on studies from western for CD4+T-lymphocyte reference values, which could, often be unreliable for usage in local settings. To establish the normal reference values of T lymphocyte subsets from healt...

OBJECTIVE Immunophenotyping of blood lymphocytes is an important tool in the diagnosis of hematologic and immunologic disorders. Because of maturation and expansion of the immune system in the first years of life, the relative and the absolute size of lymphocyte subpopulations vary during childhood. Therefore we wished to obtain reference values for the relative and the absolute size of all rel...

BACKGROUND The enumeration of absolute CD4 counts is of primary importance, since therapeutic protocols for HIV1 patients are based on these. AIMS To establish reference ranges for the CD4 and CD8 T-lymphocytes in the Indian population. SETTINGS AND DESIGN Enumeration of absolute numbers and percentages of lymphocyte subsets was performed in 252 healthy adult Indians. METHODS AND MATERIAL...

BACKGROUND Fingolimod is a drug administered orally to adult patients treated for relapsing remitting course of multiple sclerosis (MS). Mode of action of fingolimod is based on intense S1P1 receptor stimulation and "arresting" lymphocytes in lymphatic organs. Objective of the research was to assess changes in the frequencies of basic lymphocyte subsets in patients treated for multiple sclerosi...
