Every connected simple graph G has an acyclic orientation. Deene a graph AO(G) whose vertices are the acyclic orientations of G and whose edges join orientations that diier by reversing the direction of a single edge. It was known previously that AO(G) is connected but not necessarily Hamiltonian. However, Squire 3] proved that the square AO(G) 2 is Hamiltonian. We prove the slightly stronger r...

Alcohol oxidase (AO) is a peroxisomal enzyme that catalyses the first step in methanol metabolism in yeast. Monomeric, inactive AO protein is synthesised in the cytosol and subsequently imported into peroxisomes, where the enzymatically active, homo-octameric form is found. The mechanisms involved in AO octamer assembly are largely unclear. Here we describe the isolation of Hansenula polymorpha...

Objective- The aim of this study was to assess ultrasonography-derived caudal vena cava to aorta ratio (CVC/Ao) as a novel endpoint in the resuscitation of experimental hemorrhagic shock in dogs. Design- Experimental study. Animals- Ten adult mongrel healthy dogs. Procedures- After induction of anesthesia (con...

In this paper we present a comparative analysis of several currently available Java based dynamic AO systems. The comparison is built on how these systems deal with general dynamic reconfiguration problems. Through this exercise we hope to better understand weather and how do the specific AO change support mechanisms (e.g. total, actual, or collected weaving) affect dynamic system reconfigurabi...

Arabinogalactan-proteins (AGPs) are highly glycosylated hydroxyproline (Hyp)-rich glycoproteins that are frequently characterized by the presence of [Alanine-Hyp] ([AO]) repetitive units. AGP galactosyltransferase (GalT) activities in tobacco (Nicotiana tabacum) and Arabidopsis (Arabidopsis thaliana) microsomal membranes were studied here with an in vitro GalT reaction system, which used accept...

BACKGROUND The fixed threshold criterion for the ratio of forced expiratory volume in the first second to forced vital capacity (FEV1/FVC) <0.7 is widely applied for diagnosis of airflow obstruction (AO). However, this fixed threshold criterion may misidentify AO, because thresholds below the fifth percentile of normal FEV1/FVC (lower limit of normal; LLN) vary with age. This study aims to iden...

After immobilization, patients show impaired postural control and increased risk of falling. Therefore, loss of balance control should already be counteracted during immobilization. Previously, studies have demonstrated that both motor imagery (MI) and action observation (AO) can improve motor performance. The current study elaborated how the brain is activated during imagination and observatio...

Neste artigo apresentamos o trabalho desenvolvido na realiza c~ao do AUDIMUS, um sistema de reconhecimento de fala cont nua para o Português europeu. Para a realiza c~ao de um sistema deste tipo foi necess ario recolher e desenvolver os diferentes componentes que s~ao dependentes da l ngua, como sejam uma base de dados de fala e respectiva segmenta c~ao e etiquetagem, grandes quantidades de tex...
