Abstract Let $G$ be a connected complex semi-simple Lie group and ${\mathcal {B}}$ its flag variety. For every positive integer $n$, we introduce Poisson groupoid over ${{\mathcal {B}}}^n$, called the $n$th total configuration of flags $G$, which contains family sub-groupoids whose spaces are generalized double Bruhat cells bases Schubert in {B}}^n$. Certain symplectic leaves these then shown t...

Abstract Case report: a 81 years old man with systemic hypertension, dyslipidemia, past smoking habit, was admitted to the ER of our hospital acute decompensated heart failure. Since July he complained worsening dyspnea and paroxysmal nocturnal dyspnea. His blood pressure 155/80 mmHg, HR 78 bpm in atrial fibrillation. He reported myocardial infarction at age 32, thenceforth underwent periodic c...

UNLABELLED To evaluate whether scintigraphy with (99m)Tc-labeled white blood cells (WBC) can assess the intensity of bowel inflammation, a large dataset of laboratory values and clinical activity indices was correlated with (99m)Tc-WBC scintigraphy in children with Crohn's disease (CD), ulcerative colitis (UC), and miscellaneous colitis (MC). Also evaluated was whether stratification of childre...

BACKGROUND Recipient exposure to allogeneic donor WBCs results in transfusion complications for selected populations of recipients. Whether or not WBC reduction should be universally applied is highly controversial. STUDY DESIGN AND METHODS In a general hospital, a randomized, controlled clinical trial of conversion to universal WBC reduction was conducted. Patients (11%) with established med...

An abstract polytope of rank n is said to be chiral if its automorphism group has two orbits on the flags, such that adjacent flags belong to distinct orbits. Examples of chiral polytopes have been difficult to find. A “mixing” construction lets us combine polytopes to build new regular and chiral polytopes. By using the chirality group of a polytope, we are able to give simple criteria for whe...

A novel technique of adding positionwise flags to one-level finite state lexicons is presented. The proposed flags are kinds of morphophonemic markers and they constitute a flexible method for describing morphophonological processes with a formalism that is tightly coupled with lexical entries and rule-like regular expressions. The formalism is inspired by the techniques used in two-level rule ...

We present a number of improvements of the basic variant of the arc-flag acceleration (Lauther, 1997, 2004) for point-to-point (P2P) shortest path computations on large graphs. Arc-flags are a modification to the standard Dijkstra algorithm and are used to avoid exploring unnecessary paths during shortest path computation. We assume that for the same input graph the shortest path problem has to...

The aim of this study was to describe personal assistants’ risks for harmful effects in client transfer situations at work. Observation and assessment of their working postures in transfer situations were performed by the Swedish ergonomic regulations concerning “red flags” (AFS 1998:1), by video recordings and by biomechanical analysis. The results showed that among eight home care assistants,...
