The beam pointing of a multi-terawatt laser wave laser is stabilized on a millisecond time scale using an active control system. Two piezo mirrors, two position sensing detectors, and a computer based optimization program ensure that both near- and far-field are stable, even during single shot operation. A standard deviation for the distribution of laser shots of 2.6 μ rad is achieved.
LKB1 is a master kinase that regulates metabolism and growth through adenosine monophosphate-activated protein kinase (AMPK) and 12 other closely related kinases. Liver-specific ablation of LKB1 causes increased glucose production in hepatocytes in vitro and hyperglycaemia in fasting mice in vivo. Here we report that the salt-inducible kinases (SIK1, 2 and 3), members of the AMPK-related kinase fa
BackgroundNew evidence indicates that increased dietary protein ingestion promotes health and recovery from illness, and also maintains functionality in older adults. The present study aimed to investigate whether a novel food service concept with protein-supplementation would increase protein and energy intake in hospitalised patients at nutritional risk. MethodsA single-blinded randomised contro
Narkosläkemedlet racemiskt ketamin är en blandning av lika delar S(+)- och R(–)-ketamin,två spegelvända läkemedelsmolekyler (sk enantiomerer) med något olika effekter.Ketamin började användas på patienter i mitten av 1960-talet och har sedan dess fascineratbåde läkare, forskare och patienter pga sina smärtstillande och sömngivande, menäven hallucinatoriska, effekter. Redan efter några års användniRacemic ketamine, introduced in the mid-sixties, contains equal proportions of the enantiomersS(+)- and R(–)-ketamine. Early clinical reports indicated unfavourable effectson intracranial pressure (ICP) and on the cerebral circulation. Current literature on thistopic is however sparse, and available reports are divergent. The aim of this doctoraldissertation project was to study cerebral and syste
The most common indication for treatment with warfarin is the prevention of ischemic stroke in patients with atrial fibrillation. Time in therapeutic range (TTR) is an important tool to evaluate the quality of anticoagulation treatment. The aim of this study was to investigate the quality of treatment and the incidence of bleeding complications in patients on warfarin treatment treated by the anti
The runoff of Iceland has been evaluated for the period 1961-1990, and changes in runoff from then to the period 2071-2100 predicted according to a future projection of climate change. The hydrological model WASIM-ETH was used, with meteorological data from the PSU/NCAR MM5 numerical weather model. The evaluation of the effects of climate change on water resources was based on a future climate sim
Current guidelines do not advocate implantation of cardioverter-defibrillators (ICD) for survivors of ventricular fibrillation (VF) during the first 48 hours of ST-elevation myocardial infarction (STEMI). However, contemporary studies in a real-life setting with long-term follow-up are lacking. We assessed the prognostic impact of early VF in a non-selected population of STEMI patients treated wit
Norovirus (NoV) is a leading cause of gastroenteritis and genotype II.4 (GII.4) is responsible for the majority of nosocomial NoV infections. Our objective was to examine whether sequencing of the capsid gene might be a useful tool for the hospital outbreak investigation to define possible transmission routes. All NoV positive samples submitted from one university hospital during the 2007/8 season
ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. Besides running with Pb ions, the physics program
Biografisk skildring av Johannes Swedborg (1824-1888), uppsalastudent och senare läroverkslektor, tidningsredaktör, kommunalman m m i Vänersborg.
A classic region of band termination at high spin occurs in rare-earth nuclei with around ten valence nucleons above the Gd-146 closed core. Results are presented here for such non-collective oblate (gamma = 60 degrees) terminating states in odd-Z Ho-155, odd-odd Ho-156, and even-even Er-156, where they are compared with neighbouring nuclei. In addition to these particularly favoured states, the o
Open access har till största delen handlat om att göra vetenskapliga tidskriftsartiklar fritt tillgängliga. Under senare år har allt flera initiativ som fokuserar på den vetenskapliga monografin kommit fram. Allt flera ser affärsmodellen för tryckta monografier inom humaniora och samhällsvetenskap som ohållbar och förlag, universitet och andra aktörer letar efter nya vägar för monografin. Den här
Measurements are presented of R-b, the ratio of the b (b) over bar cross-section to the q (q) over bar cross-section in e(+)e(-) collisions, and the forward-backward asymmetry A(FB)(b) at twelve energy points in the range root s = 130-207 GeV. These results are found to be consistent with the Standard Model expectations. The measurements are used to set limits on new physics scenarios involving co
Adenocarcinoma of the periampullary region is associated with poor prognosis and new prognostic and treatment predictive biomarkers are needed for improved treatment. Membranous expression of podocalyxin-like 1(PODXL), which is a cell-adhesion glycoprotein and stem cell marker, has been found to correlate with an aggressive tumour phenotype and adverse outcome in several cancer types. The aim of t
The proposed time-to-digital converter (TDC) arranges two Vernier gated-ring-oscillator (GRO) branches in a 2-dimension (2-D) fashion. All delay differences between X-axis phases and Y-axis phases (based on 2-D definition) can be used, rather than only the diagonal line. The large latency time inherited from Vernier structure is therefore dramatically reduced. The TDC is implemented in a 90nm CMOS
Nuclear quadrupole resonance (NQR) is a solid-state radio frequency (RF) technique, able to detect and identify compounds containing quadrupolar nuclei, including many high explosives, narcotics and pharmaceutical compounds. In addition to being able to identify entirely different compounds, the technique is also able to distinguish between different polymorphic forms of the same compound. Analysi
There are about a hundred manikin users around the world. Some of them use the manikin such as 'Walter' and 'Tore' to evaluate the comfort of clothing ensembles according to their thermal insulation and moisture resistance. A 'Walter' manikin is made of water and waterproof breathable fabric 'skin', which simulates the characteristics of human perspiration. So evaporation, condensation or sorption
BACKGROUND: Measures of prenatal environmental exposures are important, and amniotic fluid levels may directly reflect fetal exposures during hypothesized windows of vulnerability. OBJECTIVES: We aimed to detect various phthalate metabolites and perfluorooctanesulfonic acid (PFOS) in human amniotic fluid, to study temporal exposure trends, and to estimate potential associations with gestational we
