Practical scope recovery using bridge parsing

Interactive development environments (IDEs) increase programmer productivity, but unfortunately also the burden on language implementors since sophisticated tool support is expected even for small domain-specific languages. Our goal is to alleviate that burden, by generating IDEs from high-level language specifications using the JastAdd meta-compiler system. This puts increased tension on scope re

The diel activity of crucian carp, Carassius carassius, in relation to chemical cues from predators

Chemical cues from piscivorous fish and prey alarm substances often cause rapid fright responses in prey. However little is known of how piscivore-related chemical cues affect prey behaviour over periods longer than a few hours. Here we have investigated how chemical cues from piscivorous northern pike, Esox lucius, affect habitat choice and diel activity of crucian carp, Carassius carassius, over

Generation of steam tables using artificial neural networks

The industrial formulations for the thermodynamic properties of water/steam, which are approximations of the scientific one, are intended to be used in applications where computational speed is of importance, such as in power plant modelling and control. The traditional methods for implementing these tables in software imply either the use of polynomial algorithms, which demand long iteration time

A plan for (certain) failure : possibilities for and challenges of more realistic emergency plans

Calls for more robust societal emergency management capacities have grown shriller as the range of societal vulnerabilities widens. The development of workable plans is recognised as one means to increase capacity. However, scepticism persists that plans serve any significant function in guiding organisational emergency management. Plans nevertheless remain a de facto requirement for most organisa

Left Atrial Conduction along the Coronary Sinus during Ectopic Atrial Tachycardia and Atrial Fibrillation: A Study Using Correlation Function Analysis

ntroduction: Correlation function analysis was applied to endocardial electrograms to investigate conduction patterns along the coronary sinus (CS) during sinus rhythm (SR) and atrial tachycardias. Methods and Results: Eighteen recordings were obtained from 14 patients suffering from supraventricular tachycardias. Five atrial fibrillation(AF) recordings were compared to 10 SR recordings and 3 ecto

Monitoring of aortic and coronary atherosclerosis in native and non-native males of Yakutsk over 40 years

We have analyzed the development of aortic and coronary atherosclerosis over 40 years in native and non-native males of Yakutsk by comparing the data obtained in 1963-1965, 1985-1987 and 2001-2003. The research was carried out in compliance with the WHO program for the atherosclerosis epidemiology studies using autopsy material. Subjects (361 natives and 692 non-natives) included in the research d

Rehabilitation benefits highly motivated patients: a six-year prospective cost-effectiveness study

Objectives:To compare the six-year outcome of a multidisciplinary rehabilitation program with continued care within primary care in terms of health-related quality of life and cost-effectiveness. Furthermore, predictors of total costs to society were examined. Methods:A prospective, matched, controlled, six-year follow-up was designed. The study included 236 patients (42 men, 194 women) nineteen

Phase 2 study of alemtuzumab (anti-CD52 monoclonal antibody) in patients with advanced mycosis fungoides/Sezary syndrome

This phase 2 study evaluated the safety and efficacy of alemtuzumab in 22 patients with advanced mycosis fungoides/Sezary syndrome (MF/SS). Most patients had stage III or IV disease, reduced performance status, and severe itching. The overall response (OR) rate was 55%, with 32% of patients in complete remission (CR) and M in, partial remission (PR). Sezary cells were cleared from the blood in 6 o

New Communications Technology in the Context of Interactive Sound Art: an empirical analysis

In this article we discuss the notion of ‘interaction’, ‘participation’ and ‘the public’ in artistic work, specifically within the context of the exhibition The Invisible Landscapes (curated by Miya Yoshida, Malmö Konstmuseum, 2003) and etherSound (created by Henrik Frisk), a sound installation displayed in that exhibition. In this work the audience is invited to participate in the creation of new

Informal and formal care among single-living elderly in Europe.

The aims of this study were to analyse (1) whether informal care, provided by children or grandchildren to their elderly parents, and formal care are substitutes or complements, and (2) whether this relationship differs across Europe. The analyses Were based on cross-sectional data from the newly developed SHARE (Survey of Health, Ageing, and Retirement in Europe) database. We found (1) that infor

Photobleaching behavior of protoporphyrin IX during 5-aminolevulinic acid marked glioblastoma detection

The highly malignant brain tumor, glioblastoma multiforme (GBM), is difficult to fully delineate during surgical resection due to its infiltrative ingrowth and morphological similarities to surrounding functioning brain tissue. Selectiveness of GBM to 5-aminolevulinic acid (5-ALA) induced protoporphyrin IX (PpIX) is reported by other researchers to visualize tumor margins under blue light microsco

Lymphedema - A comprehensive review

Background: Lymphedema is a chronic, debilitating condition that has traditionally been seen as refractory or incurable. Recent years have brought new advances in the study of lymphedema pathophysiology. as well as diagnostic and therapeutic tools that are changing this perspective. Objective: To provide a systematic approach to evaluating and managing patients with lymphedema. Methods: We perform

The new library user in Sweden: A LibQUAL+? study at Lund University

Purpose: To examine how the library user emerges in the context of the LibQUAL+ application in Sweden in 2004. Design/methodology/approach: The paper examines the following aspects: how the information control dimension is depicted in the results of the Swedish participants; how the information control dimension compares between the Swedish implementation and other libraries; the "new user" as he

Modeling the euglycemic hyperinsulinemic clamp by stochastic differential equations

The Euglycemic Hyperinsulinemic Clamp (EHC) is the most widely used experimental procedure for the determination of insulin sensitivity. In the present study, 16 subjects with BMI between 18.5 and 63.6 kg/m(2) have been studied with a long-duration (5 hours) EHC. In order to explain the oscillations of glycemia occurring in response to the hyperinsulinization and to the continuous glucose infusion

Ascorbyl free radical and dehydroascorbate formation in rat liver endoplasmic reticulum

The mechanism of ascorbate oxidation was studied in rat liver microsomes. A continuous consumption of the added ascorbate was observed, which was accompanied with a prompt appearance of ascorbyl free radical and dehydroascorbate. Microsomes sustained steady-state level of ascorbyl free radical and dehydroascorbate till ascorbate was present in the medium. Ascorbyl free radical formation was dimini

Brain-specific NSE and S-100 proteins in umbilical blood after normal delivery

BACKGROUND: To determine normal blood levels of brain-specific proteins S-100 and neuron specific enolase (NSE) in healthy newborns and their mothers following uncomplicated birth. METHODS: Umbilical artery and vein blood and maternal venous blood was collected at 112 consecutive uncomplicated deliveries. Venous blood samples were taken from 18 of the neonates 3 days after birth. S-100 and NSE wer

Diverse responses between human pancreatic cancer cell lines to native alpha 1-antitrypsin and its C-terminal fragment.

BACKGROUND: Previous studies imply that human pancreatic cancer cells have a wide heterogeneity and their exposure to various agents may give unpredictable results in clinical situations. MATERIALS AND METHODS: The cell lines LPC-3, -5 and -10, established from primary cultures of pancreatic adenocarcinoma, were exposed to 5 microM of AAT or its C-terminal peptide C-36 for 24 hours and analysed fo

Binding of mouse nidogen-2 to basement membrane components and cells and its expression in embryonic and adult tissues suggest complementary functions of the two nidogens

Nidogen-1 binds several basement membrane components by well-defined, domain-specific interactions. Organ culture and gene targeting approaches suggest that a high-affinity nidogen-binding site of the laminin gamma1 chain (y1III4) is important for kidney development and for nerve guidance. Other proteins may also bind gamma1III4, although human nidogen-2 binds poorly to the mouse laminin gamma1 ch

Nitric oxide, islet acid glucan-1,4-alpha-glucosidase activity and nutrient-stimulated insulin secretion

The mechanism of nutrient-evoked insulin release is clearly complex. One part of that mechanism is postulated to be the activation of the glycogenolytic enzyme acid glucan-1,4-alpha-glucosidase. As nitric oxide (NO) has been found to be a potent inhibitor of glucose-stimulated insulin secretion, we have now investigated a possible influence of exogenous NO and inhibition of endogenous NO productio
