Achieving predictable and low end-to-end latency for a cloud-robotics network
To remain competitive in the field of manufacturing today, companies must make their industrial robots smarter and allow them to collaborate with one another in a more effective manner. This is typically done by adding some form of learning, or artificial intelligence (AI), to the robots. These learning algorithms are often packaged as cloud functions in a remote computational center since the amo
How a European network may help with estimating methane emissions on the French national scale
Methane emissions on the national scale in France in 2012 are inferred by assimilating continuous atmospheric mixing ratio measurements from nine stations of the European network ICOS located in France and surrounding countries. To assess the robustness of the fluxes deduced by our inversion system based on an objectified quantification of uncertainties, two complementary inversion set-ups are com

Inflammatory biomarker profiling in classical orthostatic hypotension : Insights from the SYSTEMA cohort
Objective: To investigate the inflammatory biomarker signature associated with classical orthostatic hypotension (OH). Methods: A cross-sectional study including 778 patients with unexplained syncope and/or orthostatic intolerance undergoing head-up tilt test (HUT) and supine blood sampling. Of these, 98 met diagnostic criteria of classical OH and 181 demonstrated normal haemodynamic response duri
Use of hormone replacement therapy improves the prognosis in patients with colorectal cancer : A population-based study in Sweden
The association between hormone therapy (estrogen, with or without progesterone) and colorectal cancer (CRC) has received considerable scientific interest but previous research has generated inconsistent results. We aimed to examine whether post-diagnostic use of hormone therapy might protect against CRC mortality and all-cause mortality. Women diagnosed with CRC between January 2007 and December
Directionality of nose-emitted echolocation calls from bats without a nose leaf (Plecotus auritus)
All echolocating bats and whales measured to date emit a directional bio-sonar beam that affords them a number of advantages over an omni-directional beam, i.e. reduced clutter, increased source level and inherent directional information. In this study, we investigated the importance of directional sound emission for navigation through echolocation by measuring the sonar beam of brown long-eared b
Vad avgör om kommuner investerar i bussframkomlighetsåtgärder? : Fallstudier av Stockholm, Karlstad och Köpenhamn
Framkomlighetsåtgärder för bussar i städer kan vara en viktig åtgärd för att förbättra kollektivtrafikens attraktivitet och därmed bidra till en överflyttning av resor från privatbilen till kollektivtrafiken. Många städer runt om i världen genomför framkomlighetsåtgärder och vetenskapliga studier av motiven och incitamenten för att införa sådana åtgärder har genomförts i vissa länder. Men studier
Expression of cell cycle regulators and frequency of TP53 mutations in high risk gastrointestinal stromal tumors prior to adjuvant imatinib treatment
Despite of multitude investigations no reliable prognostic immunohistochemical biomark-ers in GIST have been established so far with added value to predict the recurrence risk of high risk GIST besides mitotic count, primary location and size. In this study, we analyzed the prognostic relevance of eight cell cycle and apoptosis modulators and of TP53 mutations for prognosis in GIST with high risk
Direct top-quark decay width measurement in the tt¯ lepton+jets channel at √s=8TeV with the ATLAS experiment
This paper presents a direct measurement of the decay width of the top quark using tt¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at a centre-of-mass energy of 8 TeV and corresponds to an integrated luminosity of 20.2 fb- 1. The decay width of the top quark is measured using a template fit to distributions of ki
Neighborhoods and mortality in Sweden : Is deprivation best assessed nationally or regionally?
BACKGROUND The association between neighborhood deprivation and mortality is well established, but knowledge about whether deprivation is best assessed regionally or nationally is scarce. OBJECTIVE The present study aims to examine whether there is a difference in results when using national and county-specific neighborhood deprivation indices and whether the level of urbanization modifies the ass
Fragility of the Dirac Cone Splitting in Topological Crystalline Insulator Heterostructures
The "double Dirac cone" 2D topological interface states found on the (001) faces of topological crystalline insulators such as Pb1-xSnxSe feature degeneracies located away from time reversal invariant momenta and are a manifestation of both mirror symmetry protection and valley interactions. Similar shifted degeneracies in 1D interface states have been highlighted as a potential basis for a topolo
Adsorbate-Induced Modification of the Confining Barriers in a Quantum Box Array
Quantum devices depend on addressable elements, which can be modified separately and in their mutual interaction. Self-assembly at surfaces, for example, formation of a porous (metal-) organic network, provides an ideal way to manufacture arrays of identical quantum boxes, arising in this case from the confinement of the electronic (Shockley) surface state within the pores. We show that the electr
The human antibacterial cathelicidin, hCAP-18, is synthesized in myelocytes and metamyelocytes and localized to specific granules in neutrophils
hCAP-18 is the only human member of the antibacterial and endotoxin-binding family of proteins known as cathelicidins. The antibacterial and endotoxin binding domains reside in the C-terminal 37 amino acids of the protein (LL-37) and this is believed to be unleashed from the neutralizing N-terminus by proteases from peroxidase positive granules. In human neutrophils, peroxidase positive and peroxi

From Simulations to Simulacra of War : Game Scenarios in Cyberwar Exercises
This article explores the underlying culture of war sustaining the setting of scenarios within cyberwar games. In particular, it engages with the question of how to simulate a phenomenon that, due to its remoteness, possesses an ambivalent relation to reality. Looking at scenarios of major national and international cyberwar games as illustrations, this article, first, engages with the modes of ex
