Lake-level variability in Salar de Coipasa, Bolivia during the past ∼40,000 yr

Various paleoclimatic records have been used to reconstruct the hydrologic history of the Altiplano, relating this history to past variability of the South American summer monsoon. Prior studies of the southern Altiplano, the location of the world's largest salt flat, the Salar de Uyuni, and its neighbor, the Salar de Coipasa, generally agree in their reconstructions of the climate history of the

Light quark masses in QCD

We study the value of the light quark masses combination mu + md in QCD using both Finite Energy Sum Rules and Laplace Sum Rules. We have performed a detailed analysis of both the perturbative QCD and the hadronic parametrization inputs needed in these Sum Rules. As main result, we obtain mu (1 GeV2 + md (1 GeV2) = (12 ± 2.5) MeV for the running MS masses.

Kl4 decays beyond one loop

The matrix elements for K → ππlν decays are described by four form factors F, G, H and R. We complete previous calculations by evaluating R at next-to-leading order in the low-energy expansion. We then estimate higher order contributions using dispersion relations and determine the low-energy constants L1, L2 and L3 from data on Ke4 decays and on elastic pion scattering. Finally, we present predic

Chiral perturbation theory for η→π0γγ

The η→π0γγ decay amplitude is discussed in the general context of chiral perturbation theory assuming that the low-energy constants (counterterms) are saturated by the known meson resonances. The suppression of the lowest order contributions is understood in physical terms. A reasonable agreement with the experimental decay width is achieved.

The KL-KS mass difference

The matching of the log and short distance contributions to the KL-KS mass difference is investigated in the large Nc limit (Nc being the number of colours). In this limit a physically well defined separation between the two regimes exists. This allows for an investigation of the matching between the two contributions. We obtain that 0.8±0.1 of the observed mass difference is due to the light and

The impact of support on growth in teacher-efficacy : a cross-cultural study

Purpose: Perceived support from co-workers and managers is important for many organizational outcomes. However, the benefit of competence support from colleagues and school management on personal teacher efficacy has not been investigated. The purpose of this paper is twofold: first, to investigate the impact of competence support from colleagues and the school management on growth in teacher effi

Modeling of nucleation and growth in glass-forming alloys using a combination of classical and phase-field theory

For metallic glasses, it is of vital importance to understand the glass formation properties and to be able to predict the crystallization process in the supercooled liquid. In the present work, we model the process of nucleationand growth using a combination of classical nucleation and phase-field theory.

Calibration of river hydraulic model combined with GIS analysis using ground-based observation data

In this research a method to calibrate a river hydraulic model (HEC-RAS) using ground-based measurements of an observed flash flood is presented. Applications of the ground truth measurement of flood water depths and flooded areas within a reach of Neka River in Northern of Iran are discussed. The model is calibrated using the Manning's roughness coefficient based on 200-year flood event that took

Utvärdering av informationssystem för utrymning i hotellmiljö - Fältförsök med utrymningshissar

This report summarizes unannounced evacuation experiments in a hotel building with evacuation elevators as one of the escape routes. The participants in the experiments were wearing an eye tracking device. The results of the experiments show that there is a high acceptance for using evacuation elevators as an escape route in the evaluated type of high-rise building. The results also show that most

Search for exclusive Higgs and Z boson decays to ϕγ and ργ with the ATLAS detector

A search for the exclusive decays of the Higgs and Z bosons to a ϕ or ρ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of up to 35.6 fb−1 collected at s=13 TeV with the ATLAS detector at the CERN Large Hadron Collider. These decays have been suggested as a probe of the Higgs boson couplings to light quarks. No significant excess of events

Inclusive J/ψ production at forward and backward rapidity in p-Pb collisions at √sNN=8.16 TeV

Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sNN=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, resp

Energy dependence and fluctuations of anisotropic flow in Pb-Pb collisions at √sNN=5.02 and 2.76 TeV

Measurements of anisotropic flow coefficients with two- and multi-particle cumulants for inclusive charged particles in Pb-Pb collisions at sNN=5.02 and 2.76 TeV are reported in the pseudorapidity range |η| < 0.8 and transverse momentum 0.2 < pT < 50 GeV/c. The full data sample collected by the ALICE detector in 2015 (2010), corresponding to an integrated luminosity of 12.7 (2.0) μb−1 in the centr

BEAM DYNAMICS STUDIES OF THE ESS LINAC USING A NEW MULTICELL CAVITY MODEL

The European Spallation Source is designed to deliver 5 MW proton beam power on the target while keeping the beam induced losses below 1 W/m throughout the LINAC. This implies the need of accurate models to correctly describethe longitudinal beam dynamics within the multi-cell cavities. In all the previous error studies the cells of a multicell cavity were modelled as a sequence of independent gap

The immunomodulatory quinoline-3-carboxamide paquinimod reverses established fibrosis in a novel mouse model for liver fibrosis

Quinoline-3-carboxamides (Q substances) are small molecule compounds with anti-inflammatory properties. In this study, we used one of these substances, Paquinimod, to treat a novel model for chronic liver inflammation and liver fibrosis, the NOD-Inflammation Fibrosis (N-IF) mouse. We show that treatment of N-IF mice significantly reduced inflammation and resulted in the regression of fibrosis, eve

Comparing 18 F-AV-1451 with CSF t-tau and p-tau for diagnosis of Alzheimer disease

Objective To compare PET imaging of tau pathology with CSF measurements (total tau [t-tau] and phosphorylated tau [p-tau]) in terms of diagnostic performance for Alzheimer disease (AD). Methods We compared t-tau and p-tau and 18 F-AV-1451 in 30 controls, 14 patients with prodromal AD, and 39 patients with Alzheimer dementia, recruited from the Swedish BioFINDER study. All patients with AD (prodrom

Multinational mining companies, employment and knowledge transfer : Chile and Norway from ca. 1870 to 1940

This article compares employment at multinational mining companies in Chile and Norway from ca. 1870 to 1940. I find that multinationals in Chile recruited foreigners to managing and middle-management positions, while Norwegian workers were heavily involved in management of multinationals in Norway. The exclusion of Chileans encouraged enclave tendencies and prevented knowledge transfer, while str

Design for me?

In this paper, as a generative contrast to the notion of design “for all”, we present and discuss the potential benefits of a design “for me” approach, where the design process from the starts from, and initially is targeted at, just one person. Given many things developed for a user group or a constructed average user, in this text we describe starting from design for a single user as an alternat

Municipally Owned Enterprises as Danger Zones for Corruption? How Politicians Having Feet in Two Camps May Undermine Conditions for Accountability

The market-inspired reforms of New Public Management have been particularly pronounced in Swedish local government. Notably, municipally owned enterprises (MOEs) have rapidly grown in numbers. Principal-agent theory gives rise to the hypothesis that the massive introduction of MOEs has impacted negatively on the conditions for accountability in Swedish local government. To study this, social netwo
