Woven convolutional graph codes with large free distances

Constructions of woven graph codes based on constituent convolutional codes are studied and examples of woven convolutional graph codes are presented. The existence of codes, satisfying the Costello lower bound on the free distance, within the random ensemble of woven graph codes based on s-partite, s-uniform hypergraphs, where s depends only on the code rate, is shown.

Introducing Usability Testing in the Risk Management Process in Software Development

Human beings make errors and that is nothing that we can avoid completely. We can however lower the risk of people doing wrong in situations where, for example, medical devices are used. The overall objective of the research presented in this paper is to investigate how usability testing can contribute to software risk management process in the medical device domain. Experience has been collected

En todo caso, en cualquier caso, de todos modos, de todas maneras, de todas formas. Un estudio de las características y funciones de estos conectores

Abstract Ph. D. Dissertation at Göteborg University Title: en todo caso, en cualquier caso, de todos modos, de todas maneras, de todas formas. Un estudio de las características y funciones de estas locuciones en el español contemporáneo. English title: en todo caso, en cualquier caso, de todos modos, de todas maneras, de todas formas.

Timing of ophiolite obduction in the Grampian orogen

This study addresses the timing and pressure-temperature (P-T) conditions of ophiolite obduction, one of the proposed causes of the ca. 470 Ma Grampian orogeny of Scotland and Ireland. This event gave rise to the main structural and metamorphic characteristics of the Grampian terrane-the type area for Barrovian metamorphism, the cause of which remains enigmatic despite a century of research.

”The EU Administration of the divided Bosnian city of Mostar: Implications for EUs evolving peacebuilding approach

This article explores the EU’s efforts to reunify and reconstruct Mostar through the seminal experiment of EUAM (1994-1996), which combined peacebuilding with urban reconstruction in an innovative way. The aim is to identify lessons to be learned from the experiences of EUAM that can assist the EU to adjust its peacebuilding approach to better address post-conflict divides in cities where the EU c

Oxygen-Stabilized Rh Adatoms: 0D Oxides on a Vicinal Surface

We have investigated the initial oxidation of the Rh(113) and Rh(223) vicinal surfaces by STM and ab initio simulations. Upon adsorption of small amounts of oxygen, the surface morphology is completely altered. Surprisingly, oxygen-stabilized Rh adatoms can be observed on the (113) facets, with oxide-like electronic properties. We present models of these "0D oxide" phases and discuss reasons for t

Determining a temperature differential across a quantum dot

We present a method for determining a temperature differential across a quantum dot. If the device has a transmission function with sufficiently spaced resonant energies, then one can distinguish electrons which have tunneled from the hot lead, and those which have tunneled from the cold lead. By measuring the thermocurrent as the electrochemical potential is swept through a resonant energy level,

Unmet medical care and sexual health counseling needs-a cross-sectional study among university students in Uganda

In 2010, unmet medical care and sexual health counseling needs were assessed among students at a Ugandan University. Unmet medical care need was associated with poor mental health, experience of sexual coercion, and poor self-rated health. Unmet sexual health counseling need was significantly associated with being female, coming from an urban area, low social participation, poor mental health stat

Assimulo: A Unified Framework for ODE Solvers

During the last three decades, a vast variety of methods to numerically solve ordinary differential equations and differential algebraic equations has been developed and investigated. The methods are mostly freely available in different programming languages and with different interfaces. Accessing them using a unified interface is a need not only of the research community and for education purpos

Intestinal barrier dysfunction develops at the onset of experimental autoimmune encephalomyelitis, and can be induced by adoptive transfer of auto-reactive T cells.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system with a pathogenesis involving a dysfunctional blood-brain barrier and myelin-specific, autoreactive T cells. Although the commensal microbiota seems to affect its pathogenesis, regulation of the interactions between luminal antigens and mucosal immune elements remains unclear. Herein, we investiga

Using visual lateralization to model learning and memory in zebrafish larvae.

Impaired learning and memory are common symptoms of neurodegenerative and neuropsychiatric diseases. Present, there are several behavioural test employed to assess cognitive functions in animal models, including the frequently used novel object recognition (NOR) test. However, although atypical functional brain lateralization has been associated with neuropsychiatric conditions, spanning from schi

Interest contagion in violation-of-expectation-based false-belief tasks

In the debate about how to interpret Violation-of-Expectation (VoE) based false-belief experiments, it has been suggested that infants are predicting the actions of the agent based on more or less sophisticated cognitive means. We present an alternative, more parsimonious interpretation, exploring the possibility that the infants’ reactions are not governed by rational expectation but rather of me

The Renalase Asp37Glu polymorphism is not associated with hypertension and cardiovascular events in an urban-based prospective cohort: the Malmo Diet and cancer study

Background: Renalase (gene name RNLS), a recently discovered enzyme with monoamine oxidase activity, is implicated in the degradation of catecholamines. Recent studies delineate a possible role of this enzyme in blood pressure (BP) maintenance and cardiac protection and two single nucleotide polymorphisms, RNLS rs2576178 A > G and rs2296545 C > G have been associated with hypertension. The latter

Branched-linear polyion complexes investigated by Monte Carlo simulations

Complexes formed by one charged and branched copolymer with an oppositely charged and linear polyion have been investigated by Monte Carlo simulations. A coarse-grained description has been used, in which the main chain of the branched polyion and the linear polyion possess the same absolute charge and charge density. The spatial extension and other structural properties, such as bond-angle orient

Characteristics of Androgen Deficiency in Late-Onset Hypogonadism: Results from the European Male Aging Study (EMAS).

Context:Late-onset hypogonadism (LOH) has been defined as a syndrome in middle-aged and elderly men reporting symptoms in the presence of low testosterone (T). Objective:The objective of the study was to seek objective biochemical and end-organ evidence of androgen deficiency in men classified as having LOH according to our previously published criteria. Design, Setting, and Participants:The des

Validity, reliability, and responsiveness of a self-reported foot and ankle score (SEFAS)

Background and purpose A questionnaire was introduced by the New Zealand Arthroplasty Registry for use when evaluating the outcome of total ankle replacement surgery. We evaluated the reliability, validity, and responsiveness of the modified Swedish version of the questionnaire (SEFAS) in patients with osteoarthritis or inflammatory arthritis before and/or after their ankle was replaced or fused.

Locus Celebris : Dalby kyrka, kloster och gård aktualiserade

Locus Celebris – the Church, Monastery and Manor of Dalby actualized: An introduction to the common view on Dalby, to the research history and mediation of the place, to the international conference 24-27 April 2011 in Dalby and finally also an introduction to the conference publication.

Sociology of Law in a Digital Society - A Tweet from Global Bukowina

Is it possible to determine the Facebook Gemeinschaft or the living law of the global file sharing community? What are the social facts of twitter or the intuitive law of Chinese microbloggers? This paper argues that digitization of society, the reliance on digital networks, protocol, algorithms and completely new sets of organisational structures for social communities, have vast implications for
