We propose a model independent method to determine |Vub| from the energy spectrum of the charged lepton in inclusive semileptonic B decays. The method includes perturbative QCD corrections as well as nonperturbative ones. CERN-TH.7308/94 June 1994

OBJECTIVES To compare fetal biometric measurements with standard growth charts for ultrasound parameters existing from the last 30 years. STUDY DESIGN A preliminary prospective study. SETTING Artemisia Mean Centre of Perinatal Diagnosis, Rome,Italy. MATERIAL AND METHOD A cross sectional study involving 1000 pregnant women with uncomplicated singleton pregnancy between 14(th) and 41(th) we...

‎Suppose $n$ is a fixed positive integer‎. ‎We introduce the relative n-th non-commuting graph $Gamma^{n} _{H,G}$‎, ‎associated to the non-abelian subgroup $H$ of group $G$‎. ‎The vertex set is $Gsetminus C^n_{H,G}$ in which $C^n_{H,G} = {xin G‎ : ‎[x,y^{n}]=1 mbox{~and~} [x^{n},y]=1mbox{~for~all~} yin H}$‎. ‎Moreover‎, ‎${x,y}$ is an edge if $x$ or $y$ belong to $H$ and $xy^{n}eq y^{n}x$ or $x...

By using a double immunofluorescence method we examined the distribution of dopaminergic neurons (A17) expressing neuromedin K receptor (NKR, NK(3)) in the rat retina. The distribution of NKR-like immunoreactive (-LI) neurons partially overlapped that of tyrosine hydroxylase (TH)-LI neurons in the inner retina of section and flat-mount preparation. Neurons showing both TH- and NKR-like immunore...

We have recast the problem of t ru th maintenance in a setting of algebraic equations over Boolean lattices. If a method of labeling propositions to justi fy them according to some reasoning agent's constraints of belief happens to conform to the postulates of Boolean lattices, the labeling system can be reformulated as an algebraic equation solving system. A l l t ru th maintenance systems kno...

breast cancer is the most common type of cancer among women. the important key to treat the breast cancer is early detection of it because according to many pathological studies more than 80% of all abnormalities are still benign at primary stages; so in recent years, many studies and extensive research done to early detection of breast cancer with higher precision and accuracy.infra-red breast...

Aim: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) modulates antiviral immunity via T cells, but whether these cells are active or abundant in coronavirus disease 2019 (COVID-19) patients is unknown. The present study aimed to investigate the temporal shifting T-cell population and their subsets, T-Helper (Th) cell (CD4) T-Cytotoxic (Tc) (CD8) COVID-19 patients. Method: Thirty co...

In this note, we generalize the field theory v.s. matrix model conjecture in the case with massive fundamental flavors given by Seiberg in hep-th/0211234 to the case with massless flavors. We show that with a little modification, the analysis given by Seiberg can carry on to our case. Furthermore, this new method explains the insertion of delta functions in the matrix model given by Demasure an...

We study the Yangian symmetry of the multicomponent Quantum Nonlinear Schrödinger hierarchy in the framework of the Quantum Inverse Scattering Method. We give an explicit realization of the Yangian generators in terms of the deformed oscillators algebra which naturally occurs in this framework.
