Circular Reference Attributed Grammars - their Evaluation and Applications

This paper presents a combination of Reference Attributed Grammars (RAGs) and Circular Attribute Grammars (CAGs). While RAGs allow the direct and easy specification of non-locally dependent information, CAGs allow iterative fixed-point computations to be expressed directly using recursive (circular) equations. We demonstrate how the combined formalism, Circular Reference Attributed Grammars (CRAGs

Functional characterization of the CCL25 promoter in small intestinal epithelial cells suggests a regulatory role for caudal-related homeobox (Cdx) transcription factors

The chemokine CCL25 is selectively and constitutively expressed in the small intestinal epithelium and plays an important role in mediating lymphocyte recruitment to this site. In this study, we demonstrate that CCL25 expression in murine small intestinal epithelial cells is independent of signaling through the lymphotoxin 0 receptor and is not enhanced by inflammatory stimuli, pathways involved i

Radiological changes in asbestos cement workers

OBJECTIVE--To explore associations between exposure to asbestos cement dust and radiographic findings in lung parenchyma and pleura. METHODS--Radiographs from 174 blue collar workers and 29 white collar workers from an asbestos cement plant formed one part of the study. Progression of small opacities was further studied in those 124 blue collar workers, for whom two radiographs taken after the end

Justin and Stoic Cosmo-Theology

Abstract in UndeterminedDue to his background as a Platonist, Justin Martyr’s relation to Stoic philosophy has not gained as much attention from scholars as his relation to Platonism, and his relationship to contemporary Stoicism has been largely overlooked. The present essay provides an overview and analysis of Justin’s references and allusions to Stoics and Stoic philosophy, with particular focu

Composite Material Based on Macroporous Polyaniline and Osmium Redox Complex for Biosensor Development

Here the feasibility of layers based on the conducting polymer polyaniline (PANI) as component of glucose biosensors using glucose oxidase (GOx) as enzyme and [Os(bpy)(2)(4-aminomethylpyridine)Cl]PF6 (OsCmplx) as electrochemical mediator, is evaluated. Particularly, PANI was employed to obtain a nanostructured macroporous material (m-PANI) around polystyrene nanoparticles taken as template and the

A modified LLC panel unit root test of the PPP hypothesis

In a recent study,Westerlund (Empir Econ 37:517–531, 2009) shows that the performance of the popular LLC (Levin et al., J Econ 108:1–24, 2002) panel unit root test depends critically on the choice of lag truncation used when correcting for serial correlation, and that it is only when this parameter is set as a function of time that the power raises above size. The purpose of the current paper is t

Separation and Further Characterization of Hematopoietic Cell Populations Based on Phenotypic and Biophysical Properties

Hematopoietic stem cells (HSC) are multipotent and possess self-renewal capacity. Thus, they can sustain a life-long hematopoiesis and are also capable of restoring the hematopoietic system when transplanted to a patient. In allogeneic hematopoietic stem cell transplantation (HSCT), a potent graft-versus-leukemia (GvL) effect must be balanced against the concomitant risk of severe immunological re

Motor development following in utero exposure to organochlorines: a follow-up study of children aged 5-9 years in Greenland, Ukraine and Poland

Background: Prior studies on the association between prenatal exposure to polychlorinated biphenyls (PCBs) and dichlorodiphenyldichloroethylene (DDE) and child motor development have found contradicting results. Using data collected in the INUENDO cohort in Kharkiv (Ukraine), Warsaw (Poland) and Greenland (N = 1,103) between the years 2002 and 2012, we examined relations of prenatal exposure to 1,

A relationship between migraine and biliary tract disorders: findings in two Swedish samples of elderly twins

Objectives - To investigate whether there is a relationship between the clinical occurrence of migraine and biliary tract disorders (BTD) and to study whether there is a genetic influence on such an association. Materials and Methods - The near lifetime morbidity for migraine and BTD was examined in two Swedish twin-samples: OCTO-Twin (149 MZ and 202 DZ pairs; 234 men, 468 women; 80 years of age o

Spot Pricing in the Cloud Ecosystem: A Comparative Investigation

Background: Spot pricing is considered as a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, it seems that both providers and consumers are still hesitating to enter the Cloud spot market. The relevant academic community also has conflicting opinions about Cloud spot pricing in terms of revenue generation. Aim: This work aims to systematically ide

Respiratory uncoupling by increased H+ or K+ flux is beneficial for heart mitochondrial turnover of reactive oxygen species but not for permeability transition

Background: Ischemic preconditioning has been proposed to involve changes in mitochondrial H+ and K+ fluxes, in particular through activation of uncoupling proteins and ATP-sensitive K+ channels (MitoK(ATP)). The objectives of the present study were to explore how increased H+ and K+ fluxes influence heart mitochondrial physiology with regard to production and scavenging of reactive oxygen species

Investment in a sexual signal results in reduced survival under extreme conditions in the male great tit (Parus major)

Here, we tested for an ecologically valid cost to secondary sexual trait expression in the male great tit (Parus major). We compared the breast stripe area of a sample of males who survived extremely low night time temperatures with a sample who did not survive. Breast stripe area was significantly smaller in surviving males, suggesting a real cost of signalling in terms of survival. The relations

Breastfeeding progression in preterm infants is influenced by factors in infants, mothers and clinical practice: the results of a national cohort study with high breastfeeding initiation rates.

Many preterm infants are not capable of exclusive breastfeeding from birth. To guide mothers in breastfeeding, it is important to know when preterm infants can initiate breastfeeding and progress. The aim was to analyse postmenstrual age (PMA) at breastfeeding milestones in different preterm gestational age (GA) groups, to describe rates of breastfeeding duration at pre-defined times, as well as a

Thrombotic microangiopathy mimicking membranoproliferative glomerulonephritis

A 4-year-old boy presented with proteinuria and developed progressive renal failure over 6 years. In the patient's family, five individuals were affected with atypical haemolytic uraemic syndrome (aHUS) but not the patient. Renal biopsies (n = 3) showed glomerular basement membrane thickening with double contours, endothelial swelling and deposits of C3 and C1q. Electron microscopy revealed mesang
