Transient studies on InAs/HfO2 nanowire capacitors

Single-shot transients and deep-level transient spectroscopy are used to investigate the origins of capacitance hysteresis in n-doped InAs nanowire/HfO2 capacitors. Capacitance transients with a characteristic time in the order of 100 mu s are attributed to emission from electron traps, located in the oxide film. The trap energy is determined to be in the range from 0.12 to 0.17 eV with capture cr

Covariance Propagation and Next Best View Planning for 3D Reconstruction

This paper examines the potential benefits of applying next best view planning to sequential 3D reconstruction from unordered image sequences. A standard sequential structure-and-motion pipeline is extended with active selection of the order in which cameras are resectioned. To this end, approximate covariance propagation is implemented throughout the system, providing running estimates of the unc

DNA Binding to Zwitterionic Model Membranes.

This study shows that DNA (linearized plasmid, 4331 base pairs and salmon sperm, 2000 base pairs, respectively) adsorbs to model membranes of zwitterionic liquid crystalline phospholipid bilayers in solutions containing divalent Ca(2+) cations, and also in solutions containing monovalent Na(+). The interaction between DNA and surface-supported model membranes was followed in situ using null ellips

Comparison of bacteria and fungus-binding mesh, foam and gauze as fillers in negative pressure wound therapy - pressure transduction, wound edge contraction, microvascular blood flow and fluid retention.

Bacteria- and fungus-binding mesh binds and inactivates bacteria and fungus, which makes it interesting, alternative, wound filler for negative pressure wound therapy (NPWT). This study was conducted to compare the performance of pathogen-binding mesh, foam and gauze as wound fillers in NPWT with regard to pressure transduction, fluid retention, wound contraction and microvascular blood flow. Woun

Acquisitions and network identity change

Abstract in UndeterminedPurpose - The purpose of the paper is to discuss whether or not an acquisition changes the network identity of an acquired firm and, if so, how. This study aims to bring new insights to the corporate marketing field, as it examines corporate identity in the context of how a company is perceived because of its relationships with other firms. The focus of this research is acq

Five moments in the history of industrialized building

Industrialized building has drawn in ideas from many pioneering researchers during its decades of development; in this brief recapitulation we present some observations on selected moments in the history that have significantly shaped the approach to building construction. The first formative movement identified is prefabrication, as used by Joseph Paxton during construction of the Crystal Palace.

Factor H Autoantibodies in Patients with Antiphospholipid Syndrome and Thrombosis.

Autoantibodies to complement factor H (FH) are associated with atypical hemolytic uremic syndrome, but can also be detected in patients with rheumatoid arthritis and in patients positive for lupus anticoagulants and thus potentially antiphospholipid syndrome (APS). To our knowledge, no data are available on the association between the presence of FH autoantibodies in APS and clinical manifestation

Structural Insights into the Calcium-Mediated Allosteric Transition in the C-Terminal Domain of Calmodulin from Nuclear Magnetic Resonance Measurements.

Calmodulin is a two-domain signaling protein that becomes activated upon binding cooperatively two pairs of calcium ions, leading to large-scale conformational changes that expose its binding site. Despite significant advances in understanding the structural biology of calmodulin functions, the mechanistic details of the conformational transition between closed and open states have remained unclea

Evaluation of selective broadcast algorithms for safety applications in vehicular ad hoc networks

Just as the wireless communication technology develops further to achieve higher performance, new application areas emerge to challenge its limits. Vehicular ad hoc networks are one of these areas; and emergency situation warning is one of their most popular potential applications since traffic safety is a real concern for everyone. Due to the life-critical nature of emergency applications, howeve

Personal grievance sharing, frame alignment, and hybrid organisational structures: the role of social media in North Africa’s 2011 uprisings

The paper develops an analytical framework for understanding the role of social media in the 2011 North African uprisings. It argues that analysis of the role of Facebook, Twitter, and other social media tools should be broken down into two distinct phases: a pre-mobilisation phase and a collective action phase. Using frame analysis and the notion of connective action, the paper demonstrates that

Secondary organic aerosol formation from gasoline passenger vehicle emissions investigated in a smog chamber

Gasoline vehicles have elevated emissions of volatile organic compounds during coldstarts and idling and have recently been pointed out as potentially the main sourceof anthropogenic secondary organic aerosol (SOA) in megacities. However, there is5 a lack of laboratory studies to systematically investigate SOA formation in real-worldexhaust. In this study, SOA formation from pure aromatic precurso

Adsorption of Lipid Liquid Crystalline Nanoparticles: Effects of Particle Composition, Internal Structure, and Phase Behavior

Controlling the interfacial behavior and properties of lipid liquid crystalline nanoparticles (LCNPs) at surfaces is essential for their application for preparing functional surface coatings as well as understanding some aspects of their properties as drug delivery vehicles. Here we have studied a LCNP system formed by mixing soy phosphatidylcholine (SPC), forming liquid crystalline lamellar Struc

HIF-2α Expression Is Suppressed in SCLC Cells, Which Survive in Moderate and Severe Hypoxia When HIF-1α Is Repressed.

Small cell lung carcinoma (SCLC) is extremely aggressive and frequently metastasizes widely in its early stage. Because tumor hypoxia is related to aggressive tumor behavior and the hypoxic adaptation of SCLC is poorly documented, we stained SCLC tumors arranged in a tissue microarray for hypoxia-inducible factor (HIF)-1α and HIF-2α proteins. We found an overall lack of HIF-2α protein expression,

Evaluation of amylase testing as a tool for saliva screening of crime scene trace swabs.

Amylase testing has been used as a presumptive test for crime scene saliva for over three decades, mainly to locate saliva stains on surfaces. We have developed a saliva screening application for crime scene trace swabs, utilising an amylase sensitive paper (Phadebas((R)) Forensic Press test). Positive results were obtained for all tested dried saliva stains (0.5-32muL) with high or intermediate a

In-kind transfers of maize, commercialization and household consumption in Kenya

This article discusses in kind food transfers and whether such transfers should be interpreted as a sign of the failure of grain markets to meet the food demands of the poor. The paper elucidates on aspects of both consumption and in kind transfers of maize against a backdrop of poorly functioning markets. The paper adds to the theoretical understanding of household based linkages and provides a d
