A probabilistic analysis of argument cogency

This paper offers a probabilistic treatment of the conditions for argument cogency as endorsed in informal logic: acceptability, relevance, and sufficiency (RSA). Treating a natural language argument as a reason-claim-complex, our analysis identifies content features of defeasible argument on which the RSA conditions depend, namely: (1) change in the commitment to the reason, (2) the reason’s sens

Behavioral characteristics and injection practices associated with skin and soft tissue infections among people who inject drugs : A community-based observational study

Background: People who inject drugs (PWID) are at increased risk for bacterial skin and soft tissue infections (SSTIs). Although SSTIs pose significant health risks, little is known about their prevalence and characteristics in the population of PWID in the United States. This study investigates whether behavioral factors related to skin and equipment hygiene and tissue-damaging injection practice

Antihypertensive treatment in critical limb Ischaemia

Peripheral artery disease (PAD) is defined as atherosclerotic arterial occlusive disease of the lower extremities, manifesting as intermittent claudication (IC, pain induced by walking) or critical limb ischaemia (CLI, rest pain or ulcerations). PAD guidelines recommend strict control of cardiovascular risk factors, and European guidelines on hypertension recommend a blood pressure (BP) target < 1

Assessment of models predicting anthropogenic interventions and climate variability on surface runoff of the Lower Zab River

Multi-regression, hydrologic sensitivity and hydrologic model simulations were applied to quantify the climate change and anthropogenic intervention impacts on the Lower Zab River basin (LZRB). The Pettitt, precipitation-runoff double cumulative curve (PR-DCC) and Mann–Kendall methods were used for the change points and significant trend analyses in the annual streamflow. The long-term runoff seri

No Medium-Term Spinocerebellar Input Plasticity in Deep Cerebellar Nuclear Neurons In Vivo?

The existence of input plasticity in the deep cerebellar nuclear (DCN) cells of the adult cerebellum could have profound implications for our understanding of cerebellar function. Whereas the existence of plastic changes in mossy fiber (mf) synaptic responses in DCN neurons has been demonstrated in juvenile slices, there has so far been no direct demonstration of this form of plasticity in the adu

No evidence of publication bias in climate change science

Non-significant results are less likely to be reported by authors and, when submitted for peer review, are less likely to be published by journal editors. This phenomenon, known collectively as publication bias, is seen in a variety of scientific disciplines and can erode public trust in the scientific method and the validity of scientific theories. Public trust in science is especially important

Changes in Home and Health over Nine Years among very Old People in Latvia – Results from the ENABLE-AGE Project

To meet the needs of an increasing, heterogeneous, ageing population it is imperative to understand links between home and health. In Latvia, only limited research targeting the health and home situation of very old people is available. Consequently, the aim of this study was to describe how the home environment and aspects of health have changed over nine years between 2002 and 2011 for very old

Cerebral reorganization in patients with brachial plexus birth injury and residual shoulder problems

The functional outcome after a brachial plexus birth injury (BPBI) is based on changes in the peripheral nerve and in the central nervous system. Most patients with a BPBI recover, but residual deficits in shoulder function are not uncommon. The aim of this study was to determine cerebral activation patterns in patients with BPBI and also residual symptoms from the shoulder. In seven patients (six

The N-terminal Ankyrin Repeat domain is not required for electrophile and heat activation of the purified mosquito TRPA1 receptor

Temperature sensors are crucial for animals to optimize living conditions. The temperature response of the ion channel transient receptor potential A1 (TRPA1) is intriguing; some orthologs have been reported to be activated by cold and others by heat, but the molecular mechanisms responsible for its activation remain elusive. Single-channel electrophysiological recordings of heterologously express

Majorana bound state in a coupled quantum-dot hybrid-nanowire system

Hybrid nanowires combining semiconductor and superconductor materials appear well suited for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate the emergence of MBSs from coalescing Andreev bound states (ABSs) in a hybrid InAs nanowire with epitaxial Al, using a quantum dot at the end of the nanowire as a spectrometer. Electrostatic gating tuned the nanowire densi

The normativity of automated driving : a case study of embedding norms in technology

Autonomous driving is a technology that is currently in a phase of being developed and tested on roads in several countries. A major challenge for autonomous driving and for smart city technologies in general is regulatory challenges both regarding regulation of the technology in itself and technology as a regulator of urban space. This article examines how the development of autonomous driving em

Hospital admissions for orthostatic hypotension and syncope in later life : insights from the Malmö Preventive Project

OBJECTIVE(S):: We explored incidence, predictors, and long-term prognosis of hospital admissions attributed to reflex syncope and orthostatic hypotension. METHODS:: We analyzed a cohort of 32?628 individuals (68.2% men; age, 45.6?±?7.4 years) without prevalent cardiovascular disease over a follow-up period of 26.6?±?7.5 years. RESULTS:: One thousand and fourteen persons (3.1%, 1.2 per 1000 person-

Ion pairing and phase behaviour of an asymmetric restricted primitive model of ionic liquids

An asymmetric restricted primitive model (ARPM) of electrolytes is proposed as a simple three parameter (charge q, diameter d, and charge displacement b) model of ionic liquids and solutions. Charge displacement allows electrostatic and steric interactions to operate between different centres, so that orientational correlations arise in ion-ion interactions. In this way the ionic system may have p

TERRESTRIAL PLANETS ACROSS SPACE and TIME

The study of cosmology, galaxy formation, and exoplanets has now advanced to a stage where a cosmic inventory of terrestrial planets (TPs) may be attempted. By coupling semianalytic models of galaxy formation to a recipe that relates the occurrence of planets to the mass and metallicity of their host stars, we trace the population of TPs around both solar-mass (FGK type) and lower-mass (M dwarf) s

Measurements of biogenic volatile organic compounds at a grazed savannah grassland agricultural landscape in South Africa

Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and emit a large number of BVOCs. It is estimated on a global scale that approximately 90% of annual BVOC emissions are from terrestrial sources. In this study, measurements of BVOCs w

ON the FINE STRUCTURE SPLITTING of the 3p43d 4D5/2 and 3p43d 4D7/2 LEVELS of Fe X

We study UV spectra obtained with the SO82-B slit spectrograph on board SKYLAB to estimate the fine structure (FS) splitting of the Cl-like and levels of Fe x. The splitting is of interest because the Zeeman effect mixes these levels, producing a "magnetically induced transition" (MIT) from to for modest magnetic field strengths characteristic of the active solar corona. We estimate the splitting

Thrombus Aspiration in ST Elevation Myocardial Infarction : An Individual Patient Meta-analysis

BACKGROUND—: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration d

Purpose: To study the effectiveness of Exergames in communal psychiatry for persons with severe mental illness, a randomized cluster study was performed. The hypothesis was to increase physical activity habits to improve somatic health. To identify factors promoting or impeding the use of the Exergames. Methods: Assessments of BMI, blood pressure, physical fitness, SF36, GAF and social interaction

A combinatory antibody-antigen microarray assay for high-content screening of single-chain fragment variable clones from recombinant libraries

We have developed a combinatory antibody-antigen microarray for direct screening of multiple single-chain fragment variable (scFv) clones with no need for pre-purification or enrichment before screening. The straightforward workflow allows for early selection of binders to predefined peptide and glycopeptide targets. A capture antibody is contact printed on microarray slides, side by side with the

Gas exchange in fruits related to skin condition and fruit ripening studied with diode laser spectroscopy

The concentration of the biologically active molecular oxygen gas is of crucial importance for fruits in the metabolic respiration, maturation, and ripening processes. In our study, oxygen content and oxygen transport in fruits, exemplified by apples and guavas, were studied noninvasively by gas in scattering media absorption spectroscopy. The technique is based on the fact that free gases typical
