Crystal Structure Induced Preferential Surface Alloying of Sb on Wurtzite/Zinc Blende GaAs Nanowires

We study the surface diffusion and alloying of Sb into GaAs nanowires (NWs) with controlled axial stacking of wurtzite (Wz) and zinc blende (Zb) crystal phases. Using atomically resolved scanning tunneling microscopy, we find that Sb preferentially incorporates into the surface layer of the {110}-terminated Zb segments rather than the {1120}-terminated Wz segments. Density functional theory calcul

Performance overhead comparison between hypervisor and container based virtualization

The current virtualization solution in the Cloud widely relies on hypervisor-based technologies. Along with the recent popularity of Docker, the container-based virtualization starts receiving more attention for being a promising alternative. Since both of the virtualization solutions are not resource-free, their performance overheads would lead to negative impacts on the quality of Cloud services

The Role of a Multilateral Environmental Agreements: Greenkeeping in Virunga Park : Applying the UNESCO World Heritage Convention in the Armed Conflict of the Democratic Republic of the Congo

This article analyses the application of the 1972 United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Convention (the WHC) in the context of the armed conflicts that have taken place in the Virunga National Park (the Park), a natural world heritage site in the Democratic Republic of the Congo (the DRC). Instead of addressing wartime environmental damage under t

The putative tumor suppressor gene EphA7 is a novel BMI-1 target

Bmi1 was originally identified as a gene that contributes to the development of mouse lymphoma by inhibiting MYC-induced apoptosis through repression of Ink4a and Arf. It codes for the Polycomb group protein BMI-1 and acts primarily as a transcriptional repressor via chromatin modifications. Although it binds to a large number of genomic regions, the direct BMI-1 target genes described so far do n

Respiratory mechanics in patients ventilated for critical lung disease

Respiratory mechanics, using flow interruption, was previously studied during the complete breath in healthy ventilated man, numerical techniques relieving constraints regarding flow pattern. The classical linear model of non-Newtonian behaviour was found to be valid. The present study was extended to subjects with critical lung disease. Subjects with acute lung injury (ALI; n = 2), acute respirat

Street Art and Public Space : A digital archive

This paper aims to discuss street art as new form of art and activism of uncomissioned and unsanctioned artifacts including paintings, murals and various kinds of stencils, posters, and stickers applied in any public surface. As Bengtsen (2014) has argued street art is a sociocultural practice, which is performative, ephemeral, and site specific. Street art has much to tell us about the dialectics

A practical superconducting-microcalorimeter X-ray spectrometer for beamline and laboratory science

We describe a series of microcalorimeter X-ray spectrometers designed for a broad suite of measurement applications. The chief advantage of this type of spectrometer is that it can be orders of magnitude more efficient at collecting X-rays than more traditional high-resolution spectrometers that rely on wavelength-dispersive techniques. This advantage is most useful in applications that are tradit

Decreasing prevalence of transmitted drug resistance among ART-naive HIV-1-infected patients in Iceland, 1996–2012

Introduction: Resistance to antiretroviral drugs can complicate the management of HIV-1 infection and impair control of its spread. The aim of the current study was to investigate the prevalence and transmission of HIV-1 drug resistance among 106 antiretroviral therapy (ART)-naïve patients diagnosed in Iceland (1996–2012).Methods: HIV-1 polymerase sequences were analysed using the Calibrated Popul

Comparative construal for vicarious sensory and emotive experience

While comparative construal (categorization, analogy and metaphorization) has been the subject of considerable research in linguistics, psychology, and cognitive science, comparatively little attention has been given to its role in emotive and sensory knowledge transfer (Thagard & Shelley 2006: 27). This paper proposes an explanatory framework for comparative construal in the form of a three-d

Spatiotemporal Dynamics of the Cortical Responses Induced by a Prolonged Tactile Stimulation of the Human Fingertips

The sense of touch is fundamental for daily behavior. The aim of this work is to understand the neural network responsible for touch processing during a prolonged tactile stimulation, delivered by means of a mechatronic platform by passively sliding a ridged surface under the subject’s fingertip while recording the electroencephalogram (EEG). We then analyzed: (i) the temporal features of the Soma

Search for lepton-flavour-violating decays of the Higgs and Z bosons with the ATLAS detector

Direct searches for lepton flavour violation in decays of the Higgs and Z bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: H→ eτ, H→ μτ, and Z→ μτ. The searches are based on the data sample of proton–proton collisions collected by the ATLAS detector corresponding to an integrated luminosity of 20.3 fb - 1 at a centre-of-mass energy of s=8 TeV. No

Measurement of the tt¯Z and tt¯W production cross sections in multilepton final states using 3.2 fb -1 of pp collisions at √s = 13 TeV with the ATLAS detector

A measurement of the tt¯ Z and tt¯ W production cross sections in final states with either two same-charge muons, or three or four leptons (electrons or muons) is presented. The analysis uses a data sample of proton–proton collisions at s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015, corresponding to a total integrated luminosity of 3.2 fb- 1. The inclusive cross se

Modelling complexity in everyday operations: Functional resonance in maritime mooring at quay

Maritime operations are complex socio-technical activities, with many interacting agents. Such agents are acting based on different, sometimes conflicting, goals. The traditional approach for safety, based on decomposition and bimodality, might lead to ineffective analyses, ignoring the transient and hidden links among activities as they are performed in everyday work. In this sense, the Functiona

Heidegger's black notebooks and the future of theology

This book probes the relationship between Martin Heidegger and theology in light of the discovery of his Black Notebooks, which reveal that his privately held Antisemitism and anti-Christian sentiments were profoundly intertwined with his philosophical ideas. Heidegger himself was deeply influenced by both Catholic and Protestant theology. This prompts the question as to what extent Christian anti

PD-L1 immunohistochemistry in clinical diagnostics of lung cancer : inter-pathologist variability is higher than assay variability

Assessment of programmed cell death ligand 1 (PD-L1) immunohistochemical staining is used for decision on treatment with programmed cell death 1 and PD-L1 checkpoint inhibitors in lung adenocarcinomas and squamous cell carcinomas. This study aimed to compare the staining properties of tumor cells between the antibody clones 28-8, 22C3, SP142, and SP263 and investigate interrater variation between
