Permafrost in the Arctic is thawing, exposing large carbon and nitrogen stocks for decomposition. Gaseous carbon release from Arctic soils due to permafrost thawing is known to be substantial, but growing evidence suggests that Arctic soils may also be relevant sources of nitrous oxide (N2O). Here we show that N2O emissions from subarctic peatlands increase as the permafrost thaws. In our study, t

Many separate-sexed organisms have sex chromosomes controlling sex determination. Sex chromosomes often have reduced recombination, specialized (frequently sex-specific) gene content, dosage compensation and heteromorphic size. Research on sex determination and sex chromosome evolution has increased over the past decade and is today a very active field. However, some areas within the field have no

Cet article explore une nouvelle théorie méta-éthique selon laquelle les jugements de valeur sont des expressions d’une sorte de croyance conditionnelle de celui qui émet ces jugements. Les jugements de valeur expriment la croyance que quelque chose est le cas à condition de que quelque chose d’autre soit le cas. L’objectif est ici de parvenir à une meilleure compréhension de ce point de vue. À ceThis paper explores a novel metaethical theory according to which value judgments express conditional beliefs held by those who make them. Each value judgment expresses the belief that something is the case on condition that something else is the case. The paper aims to reach a better understanding of this view and to highlight some of the challenges that lie ahead. The most pressing of these revo

In April 1998 Giles and Lawrence published an article in Science on the search engines' coverage of the WWW.Their result was that HotBot covered more webpages (34 %) than AltaVista (28 %). This doesn't correspond with the search engines' own data in respect to their size as well as with the experiences of the authors. The aim of this article is to compare the hit rates of both systems related to s

An inclusive search for a new-physics signature of lepton-jet resonances has been performed by the ATLAS experiment. Scalar leptoquarks, pair-produced in pp collisions at s √S13 TeV at the large hadron collider, have been considered. An integrated luminosity of 3.2 fb−1, corresponding to the full 2015 dataset was used. First (second) generation leptoquarks were sought in events with two electrons

Different approaches to anion exchange membranes (AEMs) are currently intensively investigated with the aim to develop materials for application in electrochemical energy devices such as alkaline fuel cells and electrolysers.1 One of the major challenges is to identify feasible synthetic strategies to AEM materials with sufficient long-term chemical and thermal stability. Studies of different smal

The angular distributions of Drell-Yan charged lepton pairs in the vicinity of the Z-boson mass peak probe the underlying QCD dynamics of Z-boson production. This paper presents a measurement of the complete set of angular coefficients A0−7 describing these distributions in the Z-boson Collins-Soper frame. The data analysed correspond to 20.3 fb−1 of pp collisions at s=8 TeV, collected by the ATLA

Abstract: A measurement of the cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of s=8 TeV is presented. The measurement covers the pseudorapidity ranges |ηγ | < 1.37 and 1.56 ≤ |ηγ | < 2.37 in the transverse energy range 25 < ET γ < 1500 GeV. The results are based on an integrated luminosity of 20.2 fb−1, recorded by the

A fully automatic system for abdominal organ segmentation is presented. As a first step, an organ localization is obtained via a robust and efficient feature registration method where the center of the organ is estimated together with a region of interest surrounding the center. Then, a convolutional neural network performing voxelwise classification is applied. The convolutional neural network co

The lack of a widely agreed framework to help define and align corporate brand identity constitutes a serious managerial problem and a shortcoming of the academic literature. In response, this article provides such a framework, the Corporate Brand Identity Matrix (CBIM), which draws upon the relevant literature, enriched by hands-on corporate experience gained by its application in three internati

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses proton-proton collision data corresponding to an integrated luminosity of 3.2 fb-1 at s=13 TeV collected in 2015 with the ATLAS detector at the Large Hadron Collider. Events are required to have at least one jet with a transverse momentum above 250 GeV and

Contrary to the notion that altering our ordinary state of consciousnessnecessarily produces delusional beliefs and is generally deleterious, variousfindings in psychology and other disciplines suggest that 1) the ordinary stateof consciousness does not provide an accurate mapping of reality and 2) alterationsof consciousness can have various positive functions. Among themost important ones are to

Heme A is a prosthetic group in many respiratory oxidases. It is synthesised from heme B (protoheme IX) with heme O as an intermediate. In Bacillus subtilis two genes required for heme A synthesis, ctaA and ctaB, have been identified. CtaB is the heme O synthase and CtaA is involved in the conversion of heme O to heme A. A ctaB paralogue, yjdK, has been identified through the B. subtilis genome se

A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 fb-1 of pp collisions at √ s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are inte
