Organic acids, central to terrestrial carbon metabolism and atmospheric photochemistry, are ubiquitous in the troposphere in the gas, particle, and aqueous phases. As the dominant organic acids in the atmosphere, formic acid (FA, HCOOH) and acetic acid (AA, CH3COOH) control precipitation acidity in remote regions and may represent a critical link between the terrestrial carbon and water cycles by
Over the past few years, wireless mesh networks are emerging as a strong technology for cheap wireless coverage. Despite recent advances in wireless mesh networking, many research challenges remain in all protocol layers. Since a mesh network usually has very different characteristics than those of current fixed mobile networks, traditional fixed deployments such as those in cellular IP and HMIP w
In this article we address the problem of projective reconstruction of structure and motion given only image data. In particular we investigate three novel minimal combinations of points and lines over three views, and give complete solutions and reconstruction methods for two of these cases: 'four points and three lines in three views', and 'two points and six lines in three views'. We show that
Objective: Systemic lupus erythematosus (SLE) is a complex multi-organ disease, characterised by relapses and remissions. Designing a high-quality randomised controlled trial poses many challenges. We have developed evidenced-based recommendations for points to consider in conducting clinical trials in patients with SLE. Methods: The EULAR Task Force on SLE comprised 19 specialists and a clinical

Background: The development of factor (F) VIII neutralizing alloantibodies (inhibitors) is a major complication of treatment with FVIII concentrates in hemophilia A and the etiology is still poorly understood. The low-affinity Fc gamma receptors (Fc gamma R), which are expressed on immune cells, provide an important link between cellular and humoral immunity by interacting with IgG subtypes. Genet
The hyperfine structure for the 6, 7 and 8 2 S 1/2 states of 23 Na was measured by optical double-resonance techniques. The states were populated by step-wise excitation using two CW dye lasers. For the dipole interaction constant a, a(6 2 S 1/2 ) = 37.5(2) MHz, a(7 2 S 1/2 )=20.9(1) MHz, a(8 2 S 1/2 )=12.85(10) MHz. were obtained. Theoretical calculations of the hyperfine structure were performed
The Be 1s core level photoemission line from metallic Be is shown to contain unexpected internal fine structure. We argue that this fine structure is caused by intrinsic excitation of a narrow band of optical phonons in the 1s photoemission process. The general importance of the present results for high resolution core level photoemission investigations of metals is pointed out.
A measurement of dielectron production in proton-proton (pp) collisions at s=13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. This enables the investigation of a kinematic domain at low dielectron (ee) invariant mass mee and pair transverse momentum pT,ee that was previously inaccessible at the
Assessing status of natural resources and ecosystem components is pivotal for management, where indicators or indices often are used as proxies of ecological state. Many indicators, however, lack reference points and are associated with sampling errors and environmental noise, limiting their usefulness in management. Here we present a method for assessing state changes in ecological indicator from
There is much literature on the topic of statistical comparability of African countries. However, the focus on Africa has left an information gap for other regions. This paper aims to fill some of that gap by comparing GDP data on Asian countries from some of the most frequently used datasets. Additionally, by comparing the base years and versions of the system of national accounts of Asian countr
A 5-year retrospective study of the frequency of sensitization to the 25 allergens of the European standard series (ESS) was conducted in 10 centres in 8 European countries. Included were the results of 26 210 patients. The range in sensitivities differed moderately between the centres. Combining results of different centres and drawing conclusions on incidences can be done only with great care. T
Although satellite-based sensors have made vegetation data series available for several decades, the detection of vegetation trend and change is not yet straightforward. This is partly due to the scarcity of available change detection algorithms suitable for identifying and characterizing both abrupt and non-abrupt changes, without sacrificing accuracy or computational speed. We propose a user-fri
We fabricate a single billiard, a double billiard array, and a triple billiard array by etching a GaInAs/InP heterostructure, and perform a fractal analysis of the low-temperature magneto-conductance fluctuations measured in the billiards to facilitate an empirical study of how fractals combine in a physical system. We compare our results to simulated fractal traces, and find for both experiment a
Huvudsyftet med denna rapport är att förutsäga antalet spelare i nå- gon instans av DICE: s spelplattformar, t.ex. Battlefield 3 för PC, 15 minuter i framtiden. Denna förutsägelse kan användas av företaget vid köp av molnservrar on-demand för att visa dem hur mycket de behöver köpa. Flera olika prognosmodeller undersöks och utvärderas på historisk data från 2011 till 2015. En annan fokuspunkt är hThe main goal of this thesis is to predict the number of players in some instance of DICE’s gaming platforms, e.g. Battlefield 3 for PC, 15 minutes in the future. This prediction may be used by the company when buying on-demand cloud servers to tell them how much they need to buy. Several different prediction models are examined and evaluated on historical data from 2011 to 2015. Another focus poi
