Current−Voltage Characterization of Individual As-Grown Nanowires Using a Scanning Tunneling Microscope

Utilizing semiconductor nanowires for (opto)- electronics requires exact knowledge of their current−voltage properties. We report accurate on-top imaging and I−V characterization of individual as-grown nanowires, using a subnanometer resolution scanning tunneling microscope with no need for additional microscopy tools, thus allowing versatile application. We form Ohmic contacts to InP and InAs nan

Extending Languages by Leveraging Compilers: from Modelica to Optimica

Combining attribute grammars with object-oriented programming supports a new kind of declarative programming, allowing compilers to be built in a highly extensible manner. By leveraging a base compiler, extended languages can be supported at a relatively low cost. Recent work shows the applicability of the technique to general-purpose programming languages like Java. In this article, we illustrate

Agreement between TOAST and CCS ischemic stroke classification The NINDS SiGN Study

Objective: The objective of this study was to assess the level of agreement between stroke subtype classifications made using the Trial of Org 10172 Acute Stroke Treatment (TOAST) and Causative Classification of Stroke (CCS) systems. Methods: Study subjects included 13,596 adult men and women accrued from 20 US and European genetic research centers participating in the National Institute of Neurol

A search for extraterrestrial chromite in the late Eocene Massignano section, central Italy

The late Eocene may have been a period with an enhanced flux of extraterrestrial matter to Earth related either to a comet or an asteroid shower. The evidence comes from two very large and several medium-sized impact craters, at least two microtektite-microkrystite layers, and a stratigraphic interval with enhanced extraterrestrial He-3, all within the period ca. 36.3-34.3 Ma. Here, we show that t

Nordisk frikår och ambulans kämpade i andra boerkriget.

The Nordic support to the Boer people during the South African war 1899-1902 is a rather unknown history. Approximately 150 Scandinavian emigrants fought on the Boer side in the South African war and a sixth of them were killed at the battle of Magersfontein. The corps was followed by a Scandinavian ambulance formed by one Norwegian physician (Bidenkap), three Swedish nurses and six stretcher bear

Risk of Venous Thromboembolism in Patients With Rheumatoid Arthritis and Association With Disease Duration and Hospitalization

Context Recent reports suggest that rheumatoid arthritis (RA) may be a risk factor for venous thromboembolism (VTE), particularly in conjunction with hospitalization. Using hospitalization data to identify RA and VTE may identify patients when they are at elevated risk for other reasons, obscuring the incompletely understood underlying association between RA and VTE and leading to inappropriate in

Distributed reactions in highly turbulent premixed methane/air flames Part I. Flame structure characterization

Simultaneous planar laser-induced fluorescence (PLIF) measurements of a series of reactive scalars and Rayleigh scattering measurements of temperature, i.e. CH/CH2O/OH, HCO/CH2O/OH and T/CH2O/OH, and laser Doppler anemometry (LDA) measurements are carried out to characterize the flame/turbulence interaction in various regimes of turbulent combustion, including the laminar flamelet regime, the thin

Organic amendment and fungal species in combination can alter collembolan fitness

Organic material of different origin is commonly used as fertiliser in agricultural practices. Clover and wheat straw are here used to determine the importance of organic amendment for population development of fungal feeding collembolans. Two fungal species, Alternaria infectoria and Mucor hiemalis, were inoculated in three growth substrates, clover amended soil, straw amended soil and non-amende

Ecological applications of physically based remote sensing methods

Global monitoring of vegetation using optical remote sensing has undergone rapid technological and methodological development during the past decade. Physically based methods generally apply reflectance models for interpreting remotely sensed data sets. These methods have become increasingly important in the assessment of terrestrial variables from satellite-borne and airborne images. Products bas

Coulomb excitation of a Am-242 isomeric target: E2 and E3 strengths, rotational alignment, and collective enhancement

A 98% pure Am-242m ( K = 5(-), t(1/2) = 141 years) isomeric target was Coulomb excited with a 170.5-MeV Ar-40 beam. The selectivity of Coulomb excitation, coupled with the sensitivity of Gammasphere plus CHICO, was sufficient to identify 46 new states up to spin 18h in at least four rotational bands; 11 of these new states lie in the isomer band, 13 in a previously unknown yrast K-pi = 6(-) rotati

Hardware Implementation of an Iterative Sampling Rate Converter for Wireless Communication

Abstract in Undetermined This paper presents a new technique for fractional sample rate conversion based on an iterative Sinc (ISRC) method. The proposed algorithm was evaluated against the Farrow re-sampler, and performance simulation targeting different signal-to-noise ratios show the ISRC qualifies for application in reconfigurable terminals. The architecture was implemented in 65nm CMOS techno

Novel Endogenous Antimicrobial Peptides

Antimicrobial peptides serve as a first line of defence against invading microorganisms and are an essential part of our fast innate immune system. They are ancient molecules found in all classes of life. Antimicrobial peptides rapidly kill a broad spectrum of microbes and are immunomodulatory, i.e. having additional actions influencing inflammation and other innate immune responses. Results prese

Correlation between arterial blood volume obtained by arterial spin labelling and cerebral blood volume in intracranial tumours.

OBJECTIVE: To compare measurements of the arterial blood volume (aBV), a perfusion parameter calculated from arterial spin labelling (ASL), and cerebral blood volume (CBV), calculated from dynamic susceptibility contrast (DSC) MRI. In the clinic, CBV is used for grading of intracranial tumours. MATERIALS AND METHODS: Estimates of aBV from the model-free ASL technique quantitative STAR labelling of

Apoptosis of Peripheral Blood Leukocytes in Systemic Lupus Erythematosus: Studies on Serum Induction and Complement-Dependent Clearance Mechanisms

Systemic lupus erythematosus (SLE) is an autoimmune disease involving many organ systems. The cause is not known, but a complex combination of environmental and genetic factors seems to be involved. In SLE upregulation of type I interferons, a hyperactive B-cell response, presence of autoantibodies against modified nuclear components, increased complement consumption, increased apoptosis and decre

Placing butterflies on the map - testing regional geographical resolution of three stable isotopes in Sweden using the monophagus peacock Inachis io

Stable isotope analyses of tissues have been used to help delineate natal regions and routes of migratory animals. The foundations of such studies are isotopic gradients or differences representing geographic regions and habitat used by the organism that are retained in selected tissues. We sampled peacock butterflies Inachis io on a regional level in southern Sweden to study natural variation and

New directions for management and organization studies on waste

This article presents a research agenda about waste management from the perspective of management and organization studies. The agenda suggests that scholars should draw upon research on waste governance, lean management, the circular economy, and sustainable consumption. It also suggests, in a crossdisciplinary spirit, that scholars should heed research on waste within other social sciences and t

Fatty Acid Amide Hydrolase-Dependent Generation of Antinociceptive Drug Metabolites Acting on TRPV1 in the Brain

The discovery that paracetamol is metabolized to the potent TRPV1 activator N-(4-hydroxyphenyl)-5Z, 8Z, 11Z, 14Z-eicosatetraenamide (AM404) and that this metabolite contributes to paracetamol's antinociceptive effect in rodents via activation of TRPV1 in the central nervous system (CNS) has provided a potential strategy for developing novel analgesics. Here we validated this strategy by examining
