A recent intermezzo at the Ribosome Club

Two sets of ribosome structures have recently led to two different interpretations of what limits the accuracy of codon translation by transfer RNAs. In this review, inspired by this intermezzo at the Ribosome Club, we briefly discuss accuracy amplification by energy driven proofreading and its implementation in genetic code translation. We further discuss general ways by which the monitoring base

New constraints on the geochronology and Sm-Nd isotopic characteristics of Bas-Drâa mafic dykes, Anti-Atlas of Morocco

The Precambrian inliers of the Anti-Atlas belt across the southern part of Morocco contain numerous mafic dyke and sill swarms, which are thought to represent the erosional remnants of Proterozoic Large Igneous Provinces (LIPs). As part of an extended research campaign to date and characterize these LIPs, two amphiboles from one dyke within the Bas-Drâa inlier (western Anti-Atlas) yielded consiste

A c. 1710 Ma mafic sill emplaced into a quartzite and calcareous series from Ighrem, Anti-Atlas – Morocco : Evidence that the Taghdout passive margin sedimentary group is nearly 1 Ga older than previously thought

The Taghdout Group is a passive margin sequence deposited during rifting and break-up of the northern margin of the West African craton (WAC), culminating with the creation of an oceanic basin between the northern edge of the WAC and an unknown terrane. However, the age of this passive margin has been poorly constrained. It was previously thought to be c. 800–1000 Ma on the basis of age of the con

Control Design Based on FMI: A Diesel Engine Control Case Study

Modelica allows systems to be described with reuseable components and with a high precision. To be able to use such complex models efficiently, high demands are set on tools that allow the user to extract the information needed from the models in a straight-forward manner. For this purpose, design-of-experiments techniques can be used to systematically analyze the complex models.In this paper, it

HDL-associated ApoM is anti-apoptotic by delivering sphingosine 1-phosphate to S1P1 & S1P3 receptors on vascular endothelium

Background: High-density Lipoprotein (HDL) attenuates endothelial cell apoptosis induced by different cell-death stimuli such as oxidation or growth factor deprivation. HDL is the main plasma carrier of the bioactive lipid sphingosine 1-phosphate (S1P), which it is a signaling molecule that promotes cell survival in response to several apoptotic stimuli. In HDL, S1P is bound to Apolipoprotein M (A

Implementation of an Asymmetric Relay Autotuner in a Sequential Control Language

Control applications contain both logic, sequencing, and control algorithms. A holistic view of this is seldom presented in teaching and papers. One reason is the separation of communities -- automation groups typically come from the Programmable Logic Controller (PLC) world while control engineers primarily come from the Distributed Control System (DCS) world. Both logic, sequencing, and control

Vascular risk factors in INPH : A prospective case-control study (the INPH-CRasH study)

Objective: To assess the complete vascular risk factor (VRF) profile of idiopathic normal pressure hydrocephalus (INPH) using a large sample of representative patients with INPH and population-based controls to determine the extent to which vascular disease influences INPH pathophysiology. Methods: All patients with INPH who underwent shunting in Sweden in 2008-2010 were compared to age- and sex-m

Quantum Weak Values and Logic : An Uneasy Couple

Quantum mechanical weak values of projection operators have been used to answer which-way questions, e.g. to trace which arms in a multiple Mach–Zehnder setup a particle may have traversed from a given initial to a prescribed final state. I show that this procedure might lead to logical inconsistencies in the sense that different methods used to answer composite questions, like “Has the particle t

Working conditions and workplace health and safety promotion in home care : A mixed-method study from Swedish managers’ perspectives

Today, we can see a trend toward increased psychosocial strain at work among home-care managers and staff. The aim of this study is to describe home care managers' views on their own psychosocial working conditions and on how to promote workplace health and safety in a municipality in northern Sweden. A mixed-methods design was used, including questionnaire and qualitative focus group data. The qu

Optimization, validation, and identification of two reliable antibodies for immunodetection of WNT5A

WNT5A is a secreted, noncanonical WNT signaling protein that has been reported to promote progression of several types of cancer, including oral squamous cell carcinoma. Many WNT5A antibodies are available commercially for immunohistochemistry (IHC) and western blot analysis. Validation of the primary antibodies, however, is often neglected. We characterized antibodies for detecting WNT5A by IHC a

EQ-5D utility, response and drug survival in rheumatoid arthritis patients on biologic monotherapy : A prospective observational study of patients registered in the south Swedish SSATG registry

Objectives Biologic agents have dramatically changed treatment of rheumatoid arthritis (RA). To date only scarce head-To-head data exist especially when the biological therapies are given as monotherapy without concomitant disease modifying drugs (DMARDs). Thus the objective of the current study is to evaluate treatment response of all available biological therapies with special focus on utility (

A general theory of phase noise in transconductor-based harmonic oscillators

We present a rigorous phase noise analysis of a generic harmonic oscillator where the active core can be modeled as a transconductor. Phase noise equations are derived without any specific assumption on the nature of the resonator in the oscillator; furthermore, we provide closed-form 1/f2 phase noise equations when the resonator consists of an arbitrary number of cascaded LC tanks, each tuned at

Detection of Contact Force Transients in Robotic Assembly

A robotic assembly task is usually implemented as a sequence of simple motions, and the transitions between the motions are made when some events occur. These events can usually be detected with thresholds on some signal, but faster response is possible by detecting the transient on that signal. This paper considers the problem of detecting these transients. A force-controlled assembly task is use

Electroencephalography as a prognostic tool after cardiac arrest

Multiple prognostic tools are used to evaluate prognosis for comatose survivors resuscitated after cardiac arrest (CA). Next to the clinical neurologic examination, electroencephalography (EEG) is the most commonly used method to assess prognosis. However, the reliability of EEG has been limited by varying classification systems, interrater variability, and the influence of sedation. Another impor

Follow-up of cardiac arrest survivors : Why, how, and when? a practical approach

Cardiac arrest (CA) survivors may experience cognitive, physical, or emotional problems that can affect their return to everyday activities and quality of life. To improve longterm outcomes, interventions after hospital discharge may be needed. A follow-up plan to identify CA survivors with increased risk of residual cognitive, physical, or emotional problems is important to target interventions a

Interactive effects of obesity and physical fitness on risk of ischemic heart disease

Background/Objectives:Obesity and low physical fitness are known risk factors for ischemic heart disease (IHD), but their interactive effects are unclear. Elucidation of interactions between these common, modifiable risk factors may help inform more effective preventive strategies. We examined interactive effects of obesity, aerobic fitness and muscular strength in late adolescence on risk of IHD

Work disability in newly diagnosed patients with primary sjögren syndrome

Objective. To study longterm work disability and possible predictors in newly diagnosed patients with primary Sjogren syndrome (pSS). Methods. Because we wanted to include only patients with full work availability potential, eligible patients were aged 18-62 years. Fifty-one patients (mean age 46 yrs, range 18-61 yrs, 50 women) diagnosed with pSS between January 2001 and December 2012 were include

Local perceptions of land-use change : Using participatory art to reveal direct and indirect socioenvironmental effects of land acquisitions in Kilombero Valley, Tanzania

In this study, we combine conventional qualitative approaches with a more novel approach, participatory art, to explore local perceptions of land-use change and future aspirations for development in two communities in Kilombero Valley, Tanzania. We concentrate on the effects of large-scale land acquisitions on people and the environment in an ecologically important area. Leasing of land to foreign

Effects of Liquidity on Idiosyncratic Risk

Abstract In this thesis we examine the link between idiosyncratic risk and liquidity on a sample of European equity covering the last 15 years and consisting of monthly retuns on 120 stocks. This thesis builds heavily upon an article by Speigel and Wang (2005), which demonstrates the relationship between risk and various liquidity measures on the US market. In this study idiosyncratic risk is indi
