Modelling and simulation nowadays permeate virtually any engineering activity, requiring tools capable of managing complex models efficiently. Nonetheless, whereas modern modelling languages and tools allow to construct such models even on lightweight platforms (e.g., a laptop), the same is not true when it comes to numerically integrate those models. For the latter purpose, modellers usually purs
An ultra-wideband, non-dispersive leaky lens antenna system for impulse applications has been designed, fabricated and characterized. An in-house wavelet generator is connected to the antenna to transmit 100 ps-long square pulses with center frequencies at 45, 60 and 75 GHz. It is shown that the leaky lens antenna has negligible distortion and preserves the pulse shape generated by the millimeter-
The authors examine the observed heterogeneity in self-assessed health (SAH) among the aged in India using data on health and living conditions of the elderly in India from the 60th Round of National Sample Survey (2004-2005). Results indicate that almost one fourth of the old in India rate their health as poor, and there exists considerable interstate variations in SAH ratings. Based on hypothese
Immunotherapy has shown effectiveness against experimental malignant brain tumors, but the clinical results have been less convincing most likely due to immunosuppression. Prostaglandin E2 (PGE2 ) is the key immunosuppressive product of cyclooxygenase-2 (COX-2) and increased levels of PGE2 and COX-2 have been shown in several tumor types including brain tumors. In the current study, we report enha
Acidification and N-deposition are continuous processes that alter the composition of plant communities. We investigated vegetation transitions in sandy grasslands and tested two hypotheses: (1) a shift from vegetation dominated by Koeleria glauca to one dominated by Corynephorus canescens is due to acidification and (2) a shift from vegetation dominated by K. glauca to one dominated by Arrhenathe
Purpose: To review and summarize the available literature on the effect of preservatives on the eye, to provide practical guidance for the clinical assessment of the ocular surface in glaucoma patients, and to define patient populations that might benefit from preservative-free topical intraocular pressure (IOP)-lowering agents. Methods: This manuscript is based on a combination of a literature re
Insulin is a major autoantigen in islet autoimmunity and progression to type 1 diabetes. It has been suggested that the insulin B-chain may be critical to insulin autoimmunity in type 1 diabetes. INS-IGF2 consists of the preproinsulin signal peptide, the insulin B-chain and eight amino acids of the C-peptide in addition to 138 amino acids from the IGF2 gene. We aimed to determine 1) expression of
The recently introduced Gas in Scattering Media Absorption Spectroscopy (GASMAS) technique provides novel possibilities for analysis in biophotonics. Free gas in pores or cavities is monitored with narrow-band laser radiation, which can discern the gas absorptive imprints which are typically several orders of magnitude more narrow than the features of the surrounding tissue through which the diffu
To evaluate the influence of ranibizumab on the multifocal electroretinogram (Mf-ERG), full-field electroretinogram (Ff-ERG) and optical coherence tomography (OCT) in diabetic eyes (n = 20) with macular oedema.
Vacuum chambers coated with nonevaporable getter (NEG) materials have been used in straight sections of synchrotron light sources for the past 10 years. The MAX II storage ring, where four NEG-coated insertion device vacuum chambers and three NEG-coated dipole vacuum chambers have been installed, is the first synchrotron light source to also use NEG-coated dipole vacuum chambers. In connection wit
PURPOSE: The tardigrade Richtersius coronifer has previously been shown to tolerate very high doses of low linear energy transfer (low-LET) radiation (gamma rays). The purpose of this study was to extend our knowledge on radiation tolerance in this species by investigating the dose-response to high-LET radiation in terms of protons. MATERIALS AND METHODS: Dehydrated tardigrades of the species R. c
The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y verti
Protein biomarker discovery and validation in current omics era are vital for healthcare professionals to improve diagnosis, detect cancers at an early stage, identify the likelihood of cancer recurrence, stratify stages with differential survival outcomes, and monitor therapeutic responses. The success of such biomarkers would have a huge impact on how we improve the diagnosis and treatment of pa
Purpose - In order to improve cooperation and collaboration between units, clinics and departments, many health care organizations (HCOs) have introduced process orientation. Several studies indicate problems in realizing these ambitions. The purpose of this paper is to explain and understand the success and failure of process orientation in HCOs. Design/methodology/approach - The authors conducte
Soil water chemistry in forest soils over 20years was studied at nine sites in southern Sweden. The aim was to investigate the recovery from acidification and the influence of strong sea salt episodes that occur in the region. All sites but one showed signs of recovery from acidification along with the reduced sulphur deposition, but the recovery progress was slow and the soil water was in most ca
Scientific mobility and knowledge transfer at the interregional and intraregional level, Regional Studies. The aim of this paper is to explore the extent and nature of knowledge flows which result from the international mobility of elite scientists. Based on the findings from a worldwide survey of ‘star scientists’ (that is, authors of highly cited journal articles in different research areas), it
Because the maintenance of proper developmental temperatures during avian incubation is costly to parents, embryos of many species experience pronounced variation in incubation temperature. However, the effects of such temperature variation on nestling development remain relatively unexplored. To investigate this, we artificially incubated wild blue tit (Cyanistes caeruleus L.) clutches at 35.0°,
Variations in proteins have very large number of diverse effects affecting sequence, structure, stability, interactions, activity, abundance and other properties. Although protein-coding exons cover just over 1 % of the human genome they harbor an disproportionately large portion of disease-causing variants. Variation ontology (VariO) has been developed for annotation and description of variation
