On observation distributions for state space models of population survey data.

1. State space models are starting to replace more simple time series models in analyses of temporal dynamics of populations that are not perfectly censused. By simultaneously modelling both the dynamics and the observations, consistent estimates of population dynamical parameters may be obtained. For many data sets, the distribution of observation errors is unknown and error models typically chos

The characterization of Virgo data and its impact on gravitational-wave searches

Between 2007 and 2010 Virgo collected data in coincidence with the LIGO and GEO gravitational-wave (GW) detectors. These data have been searched for GWs emitted by cataclysmic phenomena in the universe, by non-axisymmetric rotating neutron stars or from a stochastic background in the frequency band of the detectors. The sensitivity of GW searches is limited by noise produced by the detector or its

Evaluating the responsiveness of the ICOAP following hip or knee replacement

Objective: The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent' and 'constant' pain. Theses are conceptually different from 'pain on activity' and pain 'intensity' as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and diffe

Structural and optical properties of self-catalytic GaAs:Mn nanowires grown by molecular beam epitaxy on silicon substrates

Mn-doped GaAs nanowires were grown in the self-catalytic growth mode on the oxidized Si(100) surface by molecular beam epitaxy and characterized by scanning and transmission electron microscopy, Raman scattering, photoluminescence, cathodoluminescence, and electron transport measurements. The transmission electron microscopy studies evidenced the substantial accumulation of Mn inside the catalyzin

Explaining the cyclic behavior of freight transport CO2-emissions in Sweden over time

Economic growth is often considered to be the main factor behind, and tightly coupled to, the increase in freight transport work and its energy use. Recent research has quantified the relative contribution from underlying factors like value density of products, transport intensity and carbon intensity of fuel. In this work we rely on the theory of economic growth cycles in order to explain the dyn

Colon capsule endoscopy: European Society of Gastrointestinal Endoscopy (ESGE) Guideline

PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings have not yet been standardized. The aim of t

Willingness to Pay and QALYs: What Can We Learn about Valuing Foodborne Risk?

This paper examines the value of reducing foodborne risk. Previous research on the valuation of health risk has been dominated by the study of mortality risk. However, in most cases foodborne illnesses are non-fatal, so we focus on individuals' preferences for reducing morbidity risk, while also including a realistic, if remote, chance of death. We use a contingent valuation method on a Swedish sa

The Masquelet Induced Membrane Technique with BMP and a Synthetic Scaffold Can Heal a Rat Femoral Critical Size Defect.

Long bone defects can be managed by the induced membrane technique together with autologous bone graft. However, graft harvest is associated with donor site morbidity. This study investigates if a tricalcium phosphate hydroxyapatite scaffold can be used alone or in combination with bone active drugs to improve healing. Sprague Dawley rats (n = 40) were randomized into four groups. (A) scaffold, (B

Investigation of Chocolate Surfaces Using Profilometry and Low Vacuum Scanning Electron Microscopy

In this study we establish the use of optical non-contact profilometry combined with low vacuum scanning electron microscopy (LV SEM) for the investigation of lipid surfaces. We illustrate, by using profilometry, a methodology for investigation of chocolate surface topology as a function of time, in the same area of interest. Both qualitative and quantitative data analysis has been performed for p

Impact of Organized Sports on Activity, Participation, and Quality of Life in People With Neurologic Disabilities.

Physical activity and exercise is the mainstay of chronic disease prevention and health maintenance for all people with and without a disability, and clear evidence exists of the benefits among various populations with neurologic disabilities. However, the potential benefits of organized sports for people with neurologic disabilities are not as well explored. In this narrative review, current evid

Contested expectations: Trump International Golf Links Scotland, polarised visions, and the making of the Menie Estate landscape as resource

In initiating the development of a large-scale golf resort in Aberdeenshire, Trump International Golf Links Scotland made a relatively unknown site central to Scottish planning debates. A stretch of land along the North Sea coast north of Aberdeen became linked to new possible futures. Part of the site developed consisted of moving sand dunes given environmental protection as a Site of Special Sci

Zinc Complexes of a Bioinspired Binucleating Ligand Platform - Equilibria in Solution and Structures in the Solid State

The zinc(II) coordination chemistry of the bioinspired bis(tetradentate) ligand 3,5-bis{bis[2-(1-methylimidazolyl)methyl]aminomethyl}pyrazole (L) was studied in detail both in solution and in the solid state. Six different species were determined in aqueous solution by means of potentiometry within the pH range 211, namely mononuclear [ZnH2L]4+, dinuclear [Zn2L]4+, [Zn2H1L]3+ and [Zn2H2L]2+, as we

Effects of sensory modality on learned mate preferences in female swordtails

Females often base their mate selection on multiple male traits. Different cues may be weighted differently in mating decisions, and play different roles such as indicating species identity or condition. The ontogeny of preferences for each cue can differ, which may offer a proximate explanation for the differential female evaluation of multimodal traits of males. We investigated whether female pr

A reduced model for the design of glass structures subjected to impact loads

A reduced finite element model for determining the maximum principal stress of a glass pane subjected to dynamic impact load is developed and compared to a full dynamic finite element model. The reduced model is based on the Rayleigh-Ritz method. The Ritz vectors used are determined by simple static load-cases. The model is applicable to centrically and eccentrically applied impact and to glass of

The epigenetic landscape of aneuploidy: constitutional mosaicism leading the way?

The role of structural genetic changes in human disease has received substantial attention in recent decades, but surprisingly little is known about numerical chromosomal abnormalities, even though they have been recognized since the days of Boveri as partaking in different cellular pathophysiological processes such as cancer and genomic disorders. The current knowledge of the genetic and epigenet

Formation of CaCO3 Deposits on Hard Surfaces-Effect of Bulk Solution Conditions and Surface Properties

We have studied nucleation and crystal growth of calcium carbonate on hard surfaces, i.e. stainless steel and silica, at different temperatures, in relation to the corresponding bulk processes, using scanning electron microscopy (SEM), X-ray diffraction (XRD), and ellipsometry. In the bulk solution, a mixture of all three calcium carbonate crystalline polymorphs, calcite, aragonite, and vaterite,

Multiple Scattering Suppression In Planar Laser Imaging Of Dense Sprays By Means Of Structured Illumination

A novel method to reduce the multiply scattered light contribution to images recorded with planar laser imaging is demonstrated. The technique, structured laser illumination planar imaging (SLIPI), is based on spatially modulated excitation light and is tested here within the dense region of a hollow-cone spray. The main idea is to use a laser sheet that is spatially modulated along the vertical d

Clinically meaningful parameters of progression and long-term outcome of Parkinson disease: An international consensus statement.

Parkinson disease (PD) is associated with a clinical course of variable duration, severity, and a combination of motor and non-motor features. Recent PD research has focused primarily on etiology rather than clinical progression and long-term outcomes. For the PD patient, caregivers, and clinicians, information on expected clinical progression and long-term outcomes is of great importance. Today,
