3D Algebraic Iterative Reconstruction for Cone-Beam X-Ray Differential Phase-Contrast Computed Tomography.

Due to the potential of compact imaging systems with magnified spatial resolution and contrast, cone-beam x-ray differential phase-contrast computed tomography (DPC-CT) has attracted significant interest. The current proposed FDK reconstruction algorithm with the Hilbert imaginary filter will induce severe cone-beam artifacts when the cone-beam angle becomes large. In this paper, we propose an alg

Relationships between oil price shocks and stock market: An empirical analysis from China

Abstract in Undetermined This paper investigates the interactive relationships between oilpriceshocks and Chinese stock market using multivariate vector auto-regression. Oilpriceshocks do not show statistically significant impact on the real stock returns of most Chinese stock market indices, except for manufacturing index and some oil companies. Some “important” oilpriceshocks depress oil company

Consequences of orthostatic blood pressure variability in middle-aged men (The Malmö Preventive Project).

OBJECTIVE: To investigate the determinants and consequences of orthostatic hypotension in the middle-aged segment of the general population. METHODS: A population of 5722 men aged 52.6 +/- 3.6 years, previously included in the Malmö Preventive Project (n = 22 444 men), was re-screened after 5.6 +/- 1.0 years and thereafter followed up over a period of 19.6 +/- 5.3 years. RESULTS: At re-screening,

Classification of Indecent Video by Low Complexity Repetitive Motion Detection

This paper proposes a fast method for detection of indecent video content using repetitive motion analysis. Unlike skin detection, motion will provide invariant features irrespective of race and color. The video material to be evaluated is divided into short fixed-length sections. By filtering different combinations of B-frame motion vectors using adjacency in time and space, one dominant motion v

Is the wealth tax harmful to economic growth?

After abolishing the wealth tax in a number of European countries during recent decades, increasing income and wealth inequality have spurred the discussion of reintroducing a wealth tax in a number of countries. This has refuelled the heated discussion in the popular press about the wealth tax’s merits and harmful effects. The academic community has been considerably quieter on the merits and dis

Cerebrospinal fluid/plasma quotients of essential and non-essential metals in patients with Alzheimer's disease

In this study, the quotients (Q) between metal concentrations in cerebrospinal fluid (CSF) and plasma were studied in subjects with Alzheimer's disease (AD) and referents to investigate if the leakage through the blood-CSF barrier (BCB) increased with increased duration and severity of the disease. Concentrations of 18 metals (Mg, Ca, Mn, Fe, Co, Ni, Cu, Zn, Se, Rb, Sr, Mo, Cd, Sn, Sb, Cs, Hg, and

Exceptional rainfall characteristics related to erosion risk in semiarid Tunisia

The Tunisian Dorsal area is representative of the semiarid Mediterranean region in terms of water resources availability as well as exceptional rainfall characteristics, runoff generation, and soil loss risk. In this context, soil properties, surface management practices together with highly intensive rainfall make the soils vulnerable to erosion. If the exceptional rainfall characteristics are li

Towards a reflexive study of norms, norm diffusion and identity (re-)construction: The transformative power of the EU in the Western Balkans

The “constructivist turn” in International Relations has enhanced our understanding of the power of ideational phenomena such as ideas, norms and identity in world politics . This turn also paved the way for debates on normative power and norm transfer, which have proved to offer fruitful insights into EU normative power and the EU’s identity as an international actor. Exploring the modes of gover

The multiple market-exposure of waste management companies: A case study of two Swedish municipally owned companies.

This paper describes how the business model of two leading Swedish municipally owned solid waste management companies exposes them to four different but related markets: a political market in which their legitimacy as an organization is determined; a waste-as-material market that determines their access to waste as a process input; a technical market in which these companies choose what waste proc

Pain in Children and Adolescents with Cerebral Palsy A Population Based Registry Study.

AIM: We assessed prevalence and location of pain in a total population of children and adolescents with cerebral palsy (CP) based on the Gross Motor Function Classification System (GMFCS), age and gender. METHODS: This cross-sectional study was based on the last assessment of children aged 1-14 years in the combined Swedish follow-up programme and national quality register programme for CP. All

Clinical results of treating type 2 diabetic patients with sitagliptin, vildagliptin or saxagliptin - diabetes control and potential adverse events

Inhibition of dipeptidyl peptidase-4 (DPP-4) is a novel oral treatment for type 2 diabetes. DPP-4 inhibition increases insulin secretion and reduces glucagon secretion by preventing the inactivation of glucagon-like peptide-1 (GLP-1), thereby lowering glucose levels. Several DPP-4 inhibitors are in clinical development; more studies exist for sitagliptin and vildagliptin. They improve metabolic co

Visualized method of chemical enhancement mechanism on SERS and TERS

We review our developed visualization method of charge transfer (CT) for chemical enhancement mechanism on surface-enhanced Raman scattering (SERS) and tip-enhanced Raman spectroscopy (TERS). Firstly, we describe our visualization method of charge difference density, which provides direct visual evidence for photoinduced CT. And then, using the visualization method of CT, we interpreted the mechan

Redefinition of the Ilerdian Stage (early Eocene)

The Ilerdian Stage was created by Hottinger and Schaub in 1960 to accommodate a significant phase in the evolution of larger foraminifera not recorded in the northern European basins, and has since been adopted by most researchers working on shallow marine early Paleogene deposits of the Tethys domain. One of the defining criteria of the stage is a major turnover of larger foraminifera, marked by

Association between genetic variation on chromosome 9p21 and aneurysmal subarachnoid haemorrhage

Background and aim Genetic factors play a role in susceptibility to subarachnoid haemorrhage, but little is known about which genes are involved. Recently, genome wide association studies have identified the 9p21 region as a risk locus for intracranial aneurysms (IA). The aim of the present study was to examine the possible association between 9p21 and ruptured IA-that is, aneurysmal subarachnoid

Arbetsvillkor och maktrelationer i avlönat hushållsarbete

Det har funnits hushållsarbetare under mycket lång tid och i de flesta delar av världen. Det är nu ett av de vanligaste kvinnoyrkena internationellt. Under mer än ett århundrade har pågått en debatt om hushållsarbetarnas arbetsvillkor där det sagts bl.a. att arbetet är lågavlönat, fysiskt tungt, innebär långa arbetstider, kan leda till social isolering och olika former av övergrepp. Dessa arbetsvi
