Multitaper Wigner and Choi-Williams distributions with pre-determined doppler-lag bandwidth and sidelobe suppression

In this paper, a penalty function is designed and used in the computation of multitapers which correspond to the Wigner and Choi-Williams distributions. The resulting multitaper spectrogram will approximately fulfill the concentration of the distribution but will additionally suppress the cross-terms outside a predetermined Doppler-lag bandwidth. The specific region as well as the amount of cross-

Grating-based X-ray Dark-field Computed Tomography of Living Mice.

Changes in x-ray attenuating tissue caused by lung disorders like emphysema or fibrosis are subtle and thus only resolved by high-resolution computed tomography (CT). The structural reorganization, however, is of strong influence for lung function. Dark-field CT (DFCT), based on small-angle scattering of x-rays, reveals such structural changes even at resolutions coarser than the pulmonary network

Dynamic control and enhancement of laser-accelerated protons using multiple laser pulses

The use of schemes involving multiple laser pulses to enhance and control the properties of beams of protons accelerated in ultra-intense laser irradiation of planar foil targets is discussed. Specifically, the schemes include the use of a second laser pulse to produce and control preplasma expansion of the target to enhance energy coupling to the proton beam; the use of a second laser pulse to dr

Atmospheric aerosol monitoring by an elastic Scheimpflug lidar system

This work demonstrates a new approach - Scheimpflug lidar for atmospheric aerosol monitoring. The atmospheric backscattering echo of a high-power continuous-wave laser diode is received by a Newtonian telescope and recorded by a tilted imaging sensor satisfying the Scheimpflug condition. The principles as well as the lidar equation are discussed in details. A Scheimpflug lidar system operating at

A modified surgical approach to women with obstetric anal sphincter tears by separate suturing of external and internal anal sphincter. A modified approach to obstetric anal sphincter injury

Background: Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence. Methods: In a prospective study at Malmo University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sphin

Distributed Force Control of Deformable Mirrors

Large (>1 m) deformable mirrors are attractive for adaptive optics on ground-based telescopes; the mirrors typically have hundreds or thousands of actuators. The use of force actuators instead of position actuators has the potential to significantly reduce total system cost. However; the use of force actuators results in many lightly-damped structural resonances within the desired bandwidth of the

Contrasting effects of habitat area and connectivity on evenness of pollinator communities

Losses of both habitat area and connectivity have been identified as important drivers of species richness declines, but little theoretical and empirical work exists that addresses the effect of fragmentation on relative commonness of highly mobile species such as pollinating insects. With a large dataset of wild bee and butterfly abundances collected across Europe, we first tested the effect of h

Named Entity Recognition for Short Text Messages

This paper describes a named entity recognition (NER) system for short text messages (SMS) running on a mobile platform. Most NER systems deal with text that is structured, formal, well written, with a good grammatical structure, and few spelling errors. SMS text messages lack these qualities and have instead a short-handed and mixed language studded with emoticons, which makes NER a challenge on

Aspects of autoantibody epitopes in type 1 diabetes

Popular Abstract in Swedish I Sverige insjuknar två barn i autoimmun diabetes (typ 1 diabetes) varje dag. Typ 1 diabetes (T1D) är en kronisk autoimmun sjukdom som kan få livshotande konsekvenser vid utebliven behandling. Sverige har den högsta incidensen av T1D i hela världen efter Finland. Förutom att den delvis är ärftlig vet man inte vilken eller vilka faktorer som triggar sjukdomen. Sedan mittType 1 diabetes (T1D) is strongly associated with autoantibodies against insulin (IAA), glutamic acid decarboxylase 65 (GADA), insulinoma-associated protein 2 (IA-2A) and the most recently identified zinc T8 transporter (ZnT8A). Together or alone, they are important both to predict T1D and to classify diabetes at the time of clinical onset. The single nucleotide polymorphism (SNP) rs13266634 in th

Phenomenon of declining blood pressure in elderly - high systolic levels are undervalued with Korotkoff method.

BACKGROUND: Systolic blood pressure (SBP) decline has been reported in octogenarians. The aim was to study if it could be observed while measuring SBP with two methods: Korotkoff (K-BP) and Strain-Gauge-Finger-Pletysmography (SG-BP), and which of them were more reliable in expressing vascular burden. METHODS: A cohort of 703 men from a population of Malmö, Sweden, were included in "Men born in 19

Cord Management of the Term Newborn

Keeping the umbilical cord intact after delivery facilitates transition from fetal to neonatal circulation and allows a placental transfusion of a considerable amount of blood. A delay of at least 3 minutes improves neurodevelopmental outcomes in term infants. Although regarded as common sense and practiced by many midwives, implementation of delayed cord clamping into practice has been unduly slo

Physicians' attitudes toward generic substitutions of antiseizure drugs in epilepsy

OBJECTIVES: The safety of generic substitution of antiseizure drugs (ASDs) has been questioned for many years. This study aimed to identify physicians' attitudes to the generic substitution of ASDs in epilepsy and which factors were of significance when deciding on compound substitutions.MATERIAL AND METHODS: A cross-sectional web-based survey was sent to neurologists and neurology residents in pu
