Classification of bird song syllables using wigner-ville ambiguity function cross-terms

A novel feature extraction method for lowdimensional signal representation is presented. The features are useful for classification of non-stationary multi-component signals with stochastic variation in amplitudes and time-frequency locations. Using a penalty function to suppress the Wigner-Ville ambiguity function auto-terms, the proposed feature set is based on the cross-term doppler- and lag pr

Integration of reliability analysis into mini-plate fixation strategy used in human mandible fractures : Convalescence and healing periods

Purpose: The objective was to assess the reliability level of mini-plate fixation used in fracture mandibles in order to evaluate the structure stability in both convalescence and healing periods. Methods: In the convalescence period, the failure scenario is measured by the relative displacement between two fracture surfaces which should not exceed an acceptable value in order to obtain a good sta

Effects of Nozzle Diameter on Diesel Spray Flames : A numerical study using an Eulerian Stochastic Field Method

The present numerical study aims to assess the performance of an Eulerian Stochastic Field (ESF) model in simulating spray flames produced by three fuel injectors with different nozzle diameters of 100 μm, 180 μm and 363 μm. A comparison to the measurements shows that although the simulated ignition delay times are consistently overestimated, the relative differences remain below 28%. Furthermore,

Identified Hadron Production as a Function of Event Multiplicity and Transverse Spherocity in pp Collisions at √s = 7 and 13 TeV with the ALICE Detector

Över 30 år av forskning inom tungjonsfysik, Quantum ChromoDymanics (QCD) och kosmologi har etablerat vår nuvarande syn på universums tidigare stadie: kort efter Big Bang var universum fyllt av ett mycket hett och kompakt medium bestående av fria kvarkar och gluoner, den så kallade Kvarkgluon plasman (Quark--Gluon Plasma, QGP). Detta medium expanderade snabbt, och kyldes ner tills beståndsdelarnas This study reports on identified hadron production as a function of event multiplicity (dNch/dη) and transverse spherocity (SO) in proton-proton collisions at √s = 7 and 13 TeV measured with the ALICE detector at the LHC. The particle spectra and their ratios measured in high-multiplicity events show signatures of an expanding medium. Integrated particle yields as a function of multiplicity measur

Postprandial increase in energy expenditure correlates with body weight reduction in patients with type 2 diabetes receiving diet therapy

Aim: The clinical significance of energy expenditure (EE) in the treatment of type 2 diabetes has not been fully elucidated. Here we analyzed the relationships between EE and clinical measurements in patients with type 2 diabetes receiving diet therapy. Methods: A total of 100 patients (34 women and 66 men) with type 2 diabetes admitted to our hospital for glycemic control were enrolled. The parti

Characterization of pancreatic islets in two selectively bred mouse lines with different susceptibilities to high-fat diet-induced glucose intolerance

Hereditary predisposition to diet-induced type 2 diabetes has not yet been fully elucidated. We recently established 2 mouse lines with different susceptibilities (resistant and prone) to high-fat diet (HFD)-induced glucose intolerance by selective breeding (designated selectively bred diet-induced glucose intolerance-resistant [SDG-R] and -prone [SDG-P], respectively). To investigate the predispo

Effect of impaired glucose tolerance on atherosclerotic lesion formation : An evaluation in selectively bred mice with different susceptibilities to glucose intolerance

Objective: Impaired glucose tolerance (IGT) is an independent risk factor for atherosclerotic cardiovascular disease. However, due to the lack of appropriate animal models, the underlying mechanisms for IGT-induced atherosclerosis remain to be elucidated invivo. We recently used selective breeding to establish 2 mouse lines with distinctively different susceptibilities to diet-induced glucose into

Selective breeding of mice for different susceptibilities to high fat diet-induced glucose intolerance : Development of two novel mouse lines, Selectively bred Diet-induced Glucose intolerance-Prone and -Resistant

Aims/Introduction: The development of type 2 diabetes is primarily due to lifestyle and environmental factors, as well as genetics, as shown by familial clustering. To establish mouse lines for evaluating heritable factors determining susceptibility to diet-induced diabetes, we performed selective breeding for differences in high fat diet (HFD)-induced glucose intolerance. Materials and Methods: S

A 76-year-old male was diagnosed to have diabetes mellitus at 57 years of age and oral hypoglycemic agents were started. Aspart, a human insulin analogue, was initiated because of a poor glycemic control in July 2009, at 74 years of age. He complained of dizziness and faintness caused by hypoglycemia in the early morning and afternoon. He was admitted to another hospital in August 2010; his plasma

Comparison of pituitary-adrenal responsiveness between insulin tolerance test and growth hormone-releasing peptide-2 test : A pilot study

Insulin tolerance test (ITT) is the gold standard for assessing the hypothalamic-pituitary-adrenal (HPA) function. GH-releasing peptide (GHRP)-2, which has a strong GH-stimulating activity, is useful for diagnosing GH deficiency as well as ITT. Additionally, GHRP-2 is also known to activate HPA axis. There have been no comparative studies of pituitary-adrenal responsiveness between GHRP-2 test and

K2-111 b - a short period super-Earth transiting a metal poor, evolved old star

Context. From a light curve acquired through the K2 space mission, the star K2-111(EPIC 210894022) has been identified as possibly orbited by a transiting planet.Aims: Our aim is to confirm the planetary nature of the object and derive its fundamental parameters.Methods: We analyse the light curve variations during the planetary transit using packages developed specifically for exoplanetary transi

Past and current cause-specific mortality in Eisenmenger syndrome

Aims: Eisenmenger syndrome (ES) is associated with considerable morbidity and mortality. Therapeutic strategies have changed during the 2000s in conjunction with an emphasis on specialist follow-up. The aim of this study was to determine the cause-specific mortality in ES and evaluate any relevant changes between 1977 and 2015. Methods and results: This is a retrospective, descriptive multicentre

The naked truth about HIV and risk taking in Swedish prisons : A qualitative study

Background: This qualitative study explores former prison inmates’ perceptions and attitudes towards HIV risk inside Swedish prisons. Method: In 2014, eight semi-structured interviews were conducted with former male prisoners to gain a deeper understanding of situations perceived to be associated with risk of HIV transmission. The material gathered from the interviews was analyzed by manifest and

Antiadrenergic autoimmunity in postural tachycardia syndrome

Aims Postural tachycardia syndrome (POTS), a common and debilitating cardiovascular disorder, is characterized by an exaggerated heart rate increase during orthostasis and a wide spectrum of adrenergic-related symptoms. To determine the aetiology of POTS, we examined a possible pathophysiological role for autoantibodies against α1-adrenergic (α1AR) and β1/2-adrenergic receptors (β1/2AR). Methods a

Defining and applying surrogate safety measures and behavioural indicators through site-based observations

This dissertation looks into surrogate safety measures and behavioural indicators that are collected through site-based observations. Surrogate safety measures are defined as measurements that are used to describe the relationship between two road users in a traffic event for the purpose of quantifying the crash probability and/or the potential crash severity in a meaningful way. The main goal of
