Detector and dispersive delay calibration issues in broadband 2D electronic spectroscopy

Precision of two-dimensional (2D) electronic spectroscopy can be affected by imprecise calibration of the optical spectrometer and coherence time delay line. This would result in 2D spectral line shapes with twisted phase, where absorptive and dispersive parts of the signal are mixed and unrecoverable. We demonstrate two efficient and easily implementable techniques for precise spectrometer and we

H2S and NO cooperatively regulate vascular tone by activating a neuroendocrine HNO-TRPA1-CGRP signalling pathway.

Nitroxyl (HNO) is a redox sibling of nitric oxide (NO) that targets distinct signalling pathways with pharmacological endpoints of high significance in the treatment of heart failure. Beneficial HNO effects depend, in part, on its ability to release calcitonin gene-related peptide (CGRP) through an unidentified mechanism. Here we propose that HNO is generated as a result of the reaction of the two

On Automation of the PID Tuning Procedure

Within process industry, and in many other areas, the PID controller is responsible for handling regulatory control. An educated guess is that the number of executing PID control loops lies in the billions (2011) and there are no signs indicating a decrease of this number. Properly tuning the PID controller, i.e., setting its parameter values based on characteristics of the process it controls t

An improved method for detecting and delineating genomic regions with altered gene expression in cancer

ABSTRACT: Genomic regions with altered gene expression are a characteristic feature of cancer cells. We present a novel method for identifying such regions in gene expression maps. This method is based on total variation (TV) minimization, a classical signal restoration technique. In systematic evaluations, we show that our method combines top-notch detection performance with an ability to delinea

Interaction between amphiphilic peptides and phospholipid membranes

This brief review aims at providing some illustrative examples on the interaction between amphiphilic peptides and phospholipid membranes an area of significant current interest Focusing on antimicrobial peptides factors affecting peptide-membrane interactions are addressed including effects of peptide length charge hydrophobicity secondary structure and topology Effects of membrane composition ar

Electrocardiographic predictors of clinical outcome in ST-elevation myocardial infarction

Malignant ventricular arrhythmias, particularly ventricular fibrillation (VF), remain an important contributor to mortality in ST-elevation myocardial infarction (STEMI). The size of myocardial injury is one more important factor influencing the prognosis of STEMI patients. The search for new non-invasive markers, which can be relatively simply calculated using conventional ECG recording and can p

The "shoulder" and the "ridge" in PHENIX

Comparison of two-particle correlations in heavy-ion collisions with measurements in proton collisions shows strong modification of the correlation shape and particle yields. Two new structures are created; both extended in Δη, one centered at Δ = 0 ('ridge') and the other occurring at Δ π ± 1.1 ('shoulder'). In these proceedings, we describe the measurements of these structures that show consiste

Nonisothermal moisture transport in hygroscopic building materials: modeling for the determination of moisture transport coefficients

A mathematical model for calculating the nonisothermal moisture transfer in building materials is presented in the article. The coupled heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as principal driving potentials. The coupled equations were solved by an analytical method, which consists of applying the Laplace transform technique and the Transfer Functi

Hematopoiesis: Functional Insights by Cell Fate Conversion

Popular Abstract in Swedish Varje dag produceras miljardtals nya blodceller, vilka exempelvis har som uppgift att transportera runt syre och försvara kroppen mot olika invaderande bakterier och virus. Dessa olika blodkomponenter har sitt ursprung i sällsynta blodbildande stamceller som återfinns i benmärgen. Dessa är så kallade vävnadsspecifika stamceller och har både förmågan att återbilda sig sjBlood cell formation, or hematopoiesis, is maintained by rare hematopoietic stem cells (HSCs) residing in the bone marrow (BM). HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in the production of mature effector blood cells. Aging is characterized

Medier och minnen

The rapid technological developments of the new millennium have presented exciting challenges to the well-established field of cultural memory studies. Today, it behoves us analyse the ways in which digital systems make it possible to store, copy, and decentralize memories, making them increasingly accessible on the Internet. The digital media offer gateways to the past that are more comprehensive

Quarrying for Claudius, protected by Min: Reflections on a small quarry in Gebel el Silsila East

Until now inscriptions have confirmed that the quarries of Gebel el Silsila East were in use until the time of Emperor Tiberius, but recent findings indicate that the quarrying process continued for at least another two generations. In one of the many smaller quarries three men carved their name repeatedly on the quarry walls, and dated their visits to a four year period, between the sixth and ten

Increased survival with mechanical ventilation in post-tuberculosis patients with the combination of respiratory failure and chest wall deformity

Background Patients who have suffered from tuberculosis are at risk of respiratory failure with hypercapnea from chest wall deformity and hypoxia from pulmonary sequelae. The combination of hypercapnea and hypoxia justifies both mechanical ventilation and oxygen therapy as treatment options. We aimed to study which treatment mode is associated with the best survival in patients with the combinatio

Preoccupied by the Past. The Case of Estonanian´s Mueum of Occupations

The article is an analysis of the Okupatsioonide Museum, The Museum of the Occupations, in Tallinn, Estonia. The analysis deals both with the content of the exhibition as well as well as the monuments of former Communists in its basement, It alse deals with "the power of place", the location of the museum and its importance in Tallinn´s "cityscape".

Modeling of Continuous Dynamic Recrystallization in Aluminum

A constitutive model is presented, considering grain size refinement through continuous dynamic recrystallization together with an evolving dislocation density. The grain refinement is allowed to influence both the evolution of the dislocation density and the rate dependence of the material. The model is calibrated against experimental data on aluminum and numerical simulations of equal channel an

Association between high dietary intake of the n-3 polyunsaturated fatty acid docosahexaenoic acid and reduced risk of Crohn's disease

Background There are plausible mechanisms for how dietary docosahexaenoic acid (DHA), an n-3 polyunsaturated fatty acid, could prevent Crohn's disease (CD). Aim To conduct a prospective study to investigate the association between increased intake of DHA and risk of CD. Methods Overall, 229702 participants were recruited from nine European centres between 1991 and 1998. At recruitment, dietary int

Engineering Open Innovation – a Framework for Fostering Open Innovation

Open innovation is an emerging innovation paradigm that can greatly accelerate technical knowledge innovation in software companies. The increasing importance and density of software in today’s products and services puts extensive pressure on excelling the discovery, description and execution of innovation. Despite that, software engineering literature lacks methods, tools and frameworks for full

Variant in the glucokinase regulatory protein (GCKR) gene is associated with fatty liver in obese children and adolescents

Recently, the single nucleotide polymorphism (SNP) identified as rs1260326, in the glucokinase regulatory protein (GCKR), was associated with hypertriglyceridemia in adults. Because accumulation of triglycerides in hepatocytes represents the hallmark of steatosis, we aimed to investigate whether this variant might be associated with fatty liver (hepatic fat content, HFF%). Moreover, because recent
