Molecular mechanisms of brain ischemia and its protection
Ischemia is defined as a reduction in blood flow to a level that is sufficient to alter normal cellular function. Brain tissue is highly sensitive to ischemia, such that even brief ischemic periods in neurons can initiate a complex sequence of events that may ultimately culminate in cell death. Stroke and cardiac arrest induce the cessation of cerebral blood flow, which can result in brain damage.
Association between shift work history and performance on the trail making test in middle-aged and elderly humans : The EpiHealth study
Shift work has been proposed to promote cognitive disturbances in humans; however, conflicting evidence is also present. By using data from 7143 middle-aged and elderly humans (45-75 years) who participated in the Swedish EpiHealth cohort study, the present analysis sought to investigate whether self-reported shift work history would be associated with performance on the trail making test (TMT). T
On the LPV control design and its applications to some classes of dynamical systems
In this chapter, a control design approach based on linear parametervarying (LPV) systems, which can be exploited to solve several problems typically encountered in control engineering, is presented. By means of recent techniques based on Youla–Kucera parametrization, it is shown how it is possible not only to design and optimize stabilizing controllers, but also to exploit the structure of the Yo
Piecewise-linear Lyapunov functions for structural stability of biochemical networks
We consider the problem of assessing structural stability of biochemical reaction networks with monotone reaction rates, namely of establishing if all the networks with a certain structure are stable regardless of specific parameter values. We investigate stability by absorbing the network equations in a linear differential inclusion and seeking for a polyhedral Lyapunov function proper to the con
Twelve months of electronic monitoring (MEMS®) in the Swedish COAST-study : a comparison of methods for the measurement of adherence in schizophrenia
The primary aim was to compare objective and subjective measures of adherence in a naturalistic cohort of schizophrenia outpatients over 12 months between October 2008 and June 2011. Antipsychotic medication adherence was monitored in 117 outpatients diagnosed with schizophrenia or schizophrenia-like psychosis according to DSM-IV criteria in a naturalistic prospective study. Adherence was determin
Taxation of Partnership - Economic national reports for the Nordic Tax Research Council's annual meeting, 2015 in Aarhus
This joint report includes economic national reports on the taxation of partnership in the Nordic countries, except Denmark. The general contents of these reports are summarized and thoroughly analyzed in Anna Holst Birket-Smith’s General report, published in this issue of the NTaxJ. For additional information, details on legislative measures etc. we find it important, however, to also publish the

Probing the gluon density of the proton in the exclusive photoproduction of vector mesons at the LHC : a phenomenological analysis
The current uncertainty on the gluon density extracted from the global parton analysis is large in the kinematical range of small values of the Bjorken-x variable and low values of the hard scale (Formula presented.). An alternative to reduces this uncertainty is the analysis of the exclusive vector meson photoproduction in photon–hadron and hadron–hadron collisions. This process offers a unique o
Cognitive functioning and employment among people with schizophrenia in vocational rehabilitation
BACKGROUND: Employment is central to recovery in schizophrenia, but little attention has been paid to its relationship with cognitive functioning. OBJECTIVE: This cross-sectional study adds to the knowledge base of relationships between cognitive functioning and gaining competitive employment, work hours per week, and monthly income among people with schizophrenia in vocational rehabilitation. It
Image analysis methods for assessing levels of image plane nonuniformity and stochastic noise in a magnetic resonance image of a homogeneous phantom
Magnetic response image plane nonuniformity and stochastic noise are properties that greatly influence the outcome of quantitative magnetic resonance imaging (MRI) evaluations such as gel dosimetry measurements using MRI. To study these properties, robust and accurate image analysis methods are required. New nonuniformity level assessment methods were designed, since previous methods were found to
Full-lifetime simulations of multiple unequal-mass planets across all phases of stellar evolution
We know that planetary systems are just as common around white dwarfs as around main-sequence stars. However, self-consistently linking a planetary system across these two phases of stellar evolution through the violent giant branch poses computational challenges, and previous studies restricted architectures to equal-mass planets. Here, we remove this constraint and perform over 450 numerical int

Detection and attenuation of feedback induced howling in hearing aids using subband zero-crossing measures
A modern hearing aid should be aesthetically appealing as well as offer sufficient and adequate signal amplification. Due to the small physical size of these devices, acoustical feedback (howling) is a major problem. Apart from the annoyance and potential hearing damaging effects that howling implies, it also reduces the supplied maximum Real Ear Aided Gain (REAG). This paper proposes a novel method
A Delay-Based Constrained Beamformer for Blind Speech Enhancement and Dereverberation
This paper presents a new microphone array method to enhance speech signals in a noisy reverberant environment. A time-delay estimation method is used for the speech source localization. The robustness of the localization method in high noise levels is provided by a subband Kurtosis-weighted structure. The estimated inter-sensor time-delays are directly used in an adaptive soft-constrained subband
Detection of Vehicle Mounted Auditory Reverse Alarm using Hidden Markov Model
-This paper presents a method for automatically detecting vehicle mounted auditory reverse alarms, or other similar warning signals, based on hidden Markov model and pattern matching techniques. The method is designed for embedded realtime platforms. The purpose of the method is to embed it with active hearing protection devices, aiding the user in detecting warning signals in low SNR environments
An old mom keeps you young: Mother’s age at last birth and offspring longevity in 19th century Utah
This study analyzes the intergenerational effects of late child bearing on offspring’s adult longevity in a population in Utah (USA) that does not display evidence of parity-specific birth control – a so-called natural fertility population. Studies have found that for women who experience late menopause and prolonged reproduction, aging is postponed and longevity is increased. This is believed to
Incompatibility Alleles; Characteristics of a 1-Locus System
The 1-locus incompatibility system that is usually assumed to be present in the red clover is investigated. The allele fluctuations from one generation to the other are demonstrated. A mathematical state model is deduced for arbitrary numbers of alleles in the population, and its steady-state behaviour and stability are discussed. The eigenvalues of the linearized models as well as simulations sho
Laminar dispersion at high Péclet numbers in finite-length channels : Effects of the near-wall velocity profile and connection with the generalized Leveque problem
This article develops the theory of laminar dispersion in finite-length channel flows at high Péclet numbers, completing the classical Taylor-Aris theory which applies for long-term, long-distance properties. It is shown, by means of scaling analysis and invariant reformulation of the moment equations, that solute dispersion in finite length channels is characterized by the occurrence of a new reg
