Spatio-temporal skin strain distributions evoke low variability spike responses in cuneate neurons
A common method to explore the somatosensory function of the brain is to relate skin stimuli to neurophysiological recordings. However, interaction with the skin involves complex mechanical effects. Variability in mechanically induced spike responses is likely to be due in part to mechanical variability of the transformation of stimuli into spiking patterns in the primary sensors located in the sk
Hybrid Microwave-Cavity Heat Engine
We propose and analyze the use of hybrid microwave cavities as quantum heat engines. A possible realization consists of two macroscopically separated quantum-dot conductors coupled capacitively to the fundamental mode of a microwave cavity. We demonstrate that an electrical current can be induced in one conductor through cavity-mediated processes by heating up the other conductor. The heat engine
An Undercooled Scree Slope Detected by Geophysical Investigations in Sporadic Permafrost below 1000 M ASL, Central Austria
Multi-method geophysical investigations, accompanied by microclimatic measurements and vegetation mapping, were performed at an undercooled scree slope near Schladming (Austria) in the eastern Alps in order to detect, map and monitor mountain permafrost. The study site, at an elevation of 990m asl, is one of the lowest-lying examples of a cold, undercooled scree slope in the Alps. Geophysical meas
Waterfowl, macrophytes, and the clear water state of shallow lakes
The importance of lake ecosystems for waterfowl remains a topic of debate. In order to assess how temporal variations in lake features, specifically shifts between alternative stable states, may interact with the waterfowl fauna, we performed a long-term (22 years) study of the shallow Lake Krankesjon, southern Sweden. Lower total numbers of waterfowl occurred during periods with low macrophyte co
Survey of central venous catheterisation practice in Sweden
BackgroundClinical guidelines on central venous catheterisation were introduced by the Swedish Society of Anaesthesiology and Intensive Care Medicine in 2011. The purpose of this study was to investigate current national practice and assess to what extent these guidelines influence clinical routines in Swedish operating wards and intensive care units. MethodsAn invitation to participate in an onli
CD81 and CD48 show different expression on blood eosinophils in systemic sclerosis: new markers for disease and pulmonary inflammation?
In systemic sclerosis (SSc)-related interstitial lung disease (ILD), elevated eosinophil counts in bronchoalveolar lavage are associated with a worse outcome. We hypothesized that eosinophils may be activated in the peripheral circulation, thereby increasing their recruitment to affected tissues and contributing to inflammation and fibrosis. The aim of this study was to characterize the blood eosi
Endotoxin markers in bronchoalveolar lavage fluid of patients with interstitial lung diseases
Background: Exposure to inhaled endotoxins (lipopolysaccharides, LPS) of Gram-negative bacteria commonly found in indoor environments and assessed in secondary tobacco smoke, has been associated with airway inflammation and asthma exacerbation. The bronchoalveolar lavage fluid (BALf) from patients with interstitial lung diseases (sarcoidosis, lung fibrosis, smoking-related ILD, eosinophilic disord
Lag-times between lympho-proliferative disorder and clinical diagnosis of chronic lymphocytic leukemia (CLL): a prospective analysis using plasma soluble CD23.
Background:CLL is a chronic disease that often progresses slowly from a precursor stage, monoclonal B-cell lymphocytosis (MBL), and that can remain undiagnosed for a long time. Methods:Within the European EPIC cohort, we measured pre-diagnostic plasma sCD23 for 179 individuals who eventually were diagnosed with CLL and an equal number of matched control subjects who remained free of cancer. Result
Tool wear and tool life of PCBN, binderless cBN and wBN-cBN tools in continuous finish hard turning of cold work tool steel
The paper presents the results of comparative study of performance of cutting tools made of ceramic-bound, binderless cBN, and wBN-cBN tool materials. The tool performance was assessed by tool wear-resistance, values of cutting forces, parameters of machined surface quality, and the state of sub-surface layer generated in continuous turning of hardened cold work tool steel. The tests were carried
Evolution of reproductive strategies in libellulid dragonflies (Odonata: Anisoptera)
In Libellulidae, oocyte production has been assumed to be continuous, with periods of egg-laying interspersed with periods of resting/eating; however, recent work suggests that two types of oocyte production are common: either (a) continuous or (b) step-wise. These are mirrored in the arrangement of the ovarioles in the ovaries. Likewise, two types of mate-guarding behavior have been observed in L
Low anthropometric measures and mortality-results from the Malmo Diet and Cancer Study
Aim. To study the association between anthropometric measures: body mass index (BMI), percent body fat, waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist-to-hip-to-height ratio (WHHR), and A Body Shape Index (ABSI); to see if individuals in the lowest 5 percentiles for these measures have an increased risk of mortality. Methods. A population-based prospective
Inhibition of metastasis in a castration resistant prostate cancer model by the quinoline-3-carboxamide tasquinimod (ABR-215050)
BACKGROUND Tasquinimod (ABR-215050) is an orally active quinoline-3-carboxamide analog that has completed phase II clinical trial in patients with castration resistant prostate cancer, showing promising inhibiting effects on the occurrence of metastasis and delayed disease progression. Its mechanism of action is not fully elucidated, but previous studies show anti-angiogenic effects and strong int
Authoritarian regime types revisited: updated data in comparative perspective
This article introduces a modified and updated version of the authoritarian regime type dataset first introduced by Hadenius and Teorell [2007. Pathways from authoritarianism. Journal of Democracy, 18 (1), 143–157]. The basic logic and merits of this dataset is presented, previously published criticism of the index is addressed and practical advice for potential users is provided. The dataset is a
Super Resolution Laser Radar with Blinking Atmospheric Particles - Application to Interacting Flying Insects
Assessment of biodiversity of pollinators on the landscape scale or estimation of fluxes of disease-transmitting biting midges constitutes a major technical challenge today. We have developed a laser-radar system for field entomology based on the so called Scheimpflug principle and a continuouswave laser. The sample-rate of this method is unconstrained by the round-trip time of the light, and the
Enzymatic Activity of Lipase-Nanoparticle Conjugates and the Digestion of Lipid Liquid Crystalline Assemblies
Variants of lipase were attached to gold nanoparticles (NPs) and their enzymatic activity was studied. The two bioengineered lipase variants have been prepared with biotin groups attached to different residues on the protein outer surface. The biotinylation was evidenced by denaturing polyacrylamide gel electrophoresis and quantified by the ([2-(4'-hydroxyazobenzene)]benzoic acid spectrophotometri
Atomic Scale Surface Structure and Morphology of InAs Nanowire Crystal Superlattices: The Effect of Epitaxial Overgrowth
While shell growth engineering to the atomic scale is important for tailoring semiconductor nanowires with superior properties, a precise knowledge of-the surface structure and morphology at different stages of this type of overgrowth has been lacking. We present a systematic scanning tunneling microscopy (STM) study of homoepitaxial Shell growth of twinned superlattices in zinc blende InAs nanowi
Drawing Planar Graphs on Points Inside a Polygon
In this paper, we study the problem of drawing a given planar graph such that vertices are at pre-specified points and the entire drawing is inside a given polygon. We give a method that shows that for an $n$-vertex graph and a $k$-sided polygon, $\Theta(kn^2)$ bends are always sufficient. We also give an example of a graph where $\Theta(kn^2)$ bends is necessary for such a drawing.
Peer Deviance, Parental Divorce, and Genetic Risk in the Prediction of Drug Abuse in a Nationwide Swedish Sample: Evidence of Environment-Environment and Gene-Environment Interaction.
IMPORTANCE Peer deviance (PD) strongly predicts externalizing psychopathologic conditions but has not been previously assessable in population cohorts. We sought to develop such an index of PD and to clarify its effects on risk of drug abuse (DA). OBJECTIVES To examine how strongly PD increases the risk of DA and whether this community-level liability indicator interacts with key DA risk factors a
A Charter Moment: Restructuring Governance for Sustainability
We are living in a highly dynamic, human-dominated Earth System in which non-linear, abrupt and irreversible changes are not only possible but also probable. These changes require institutional structures capable of steering human society away from critical tipping points and irreversible change and ensuring sustainable livelihoods for all. We see 2012 as a charter moment, a historic opportunity t
