The relationship between lymph flow and intestinal secretion was studied in an isolated, vascularly perfused cat ileal preparation in which secretion was caused by three different means: 1) plasma dilution from a constant infusion of Tyrode solution (2.5 ml/min per kg), 2) elevation of intestinal venous pressure to 30 mmHg, and 3) exposure to cholera toxin. In the plasma-dilution group, lymph f...

The first part of this paper aims at illustrating the intense scientific activity in the field of stellar rotation although, for sake of shortness, we cannot be exhaustive nor give any details. The second part is devoted to the rotation as a pertubation effect upon oscillation frequencies. The discussion focuses on one specific example: the p-modes frequency small separation which provides info...

The main results of the Tore Supra experimental programme in the years 2007-2008 are reported. They document significant progress achieved in the domain of steady-state tokamak research, as well as in more general issues relevant for ITER and for fusion physics research. Three areas are covered: ITER relevant technology developments and tests in a real machine environment, tokamak operational i...

The solution structure of monomeric stromal cell-derived factor-1alpha (SDF-1alpha), the natural ligand for the CXCR4 G-coupled receptor, has been solved by multidimensional heteronuclear NMR spectroscopy. The structure has a characteristic chemokine fold and is in excellent agreement with the individual subunits observed in the crystal structures of dimeric SDF-1alpha. Using various peptides d...

Conceptual processing of verbs consistently recruits the left posterior middle temporal gyrus (lpMTG). The left precentral motor cortex also responds to verbs, with higher activity for action than nonaction verbs. The early timing of this effect has suggested that motor features of words' meaning are accessed directly, bypassing access to conceptual representations in lpMTG. An alternative hypo...

Although the mean–variance control was initially formulated for financial portfolio management problems in which one wants to maximize the expected return and control the risk, our motivations stem from highway vehicle platoon controls that aim to maximize highway utility while ensuring zero accident. This paper develops nearoptimal mean–variance controls of switching diffusion systems. To redu...

BACKGROUND Pneumoperitoneum is usually seen after bowel perforations and surgical procedures. An increasing number of cases of non-surgical pneumoperitoneum related to sexual activity has been reported worldwide over the last years. CASE EXAMPLE: A typically young, otherwise healthy woman comes into the emergency department of Stanford University, California, complaining of recurrent chest pain...

Abstract The structure of the QFT expansion is studied in the framework of a new “Causal analytic version” of the perturbation theory. Here, the leading idea is to combine the renormalization group (RG) invariance with a general property of causality expressed in the form of the Q2–analyticity. This combining is performed by a special procedure, “analytization”. The procedure, first proposed in...

The structure of the QFT expansion is studied in the framework of a new " Invariant analytic " version of the perturbative QCD. Here, an invariant (running)coupling a(Q 2 /Λ 2) = β 1 α s (Q 2)/4π , is transformed into a " Q 2 –analytized " invariant coupling a an (Q 2 /Λ 2) ≡ A(x) , which, by constuction, is free of ghost singularities due to incorporating some nonperturbative structures. Meanw...

This article presents the setting of the controller parameters using particle swarm optimization (PSO) and its application to the load frequency control (LFC) of a power system from several sources that have different production sources as hydropower, thermal and gas power plants. A controller (PID) proportional integral derivative is used for tuning and analysis of the proposed model. The opti...
