Agreement and reliability of hepatic transient elastography in patients with chronic hepatitis C : A cross-sectional test-retest study

BACKGROUND AND AIMS: Transient elastography (TE) has largely replaced liver biopsy to evaluate fibrosis stage and cirrhosis in chronic hepatitis C. Previous studies have reported excellent reliability of TE but agreement metrics have not been reported. This study aimed to assess interrater agreement and reliability of repeated TE measurements.METHODS: Two operators performed TE independently, dire

High gas tightness ZrO2-added silicate glass sealant with low thermal stress for solid oxide fuel cells

A low leakage rate sealant of 10 wt% ZrO2-added CaO–K2O–Na2O–BaO silicate glass for SOFC has been studied. The structure of the sealant is stable at high temperatures with leakage rates less than 10−4 sccm∙cm−1, and no crystal except for ZrO2 is found in XRD analysis after heating at 800 °C for 100 h. ZrO2 is distributed in the glass matrix and plays a supporting role in avoiding over-softening at

Bumblebee flower constancy and pollen diversity over time

Bees often focus their foraging effort on a few or even a single flower species, even if other equally rewarding flower species are present. Although this phenomenon-called flower constancy-has been widely documented during single foraging trips, it is largely unknown if the behavior persists over longer time periods, especially under field conditions with large temporal variations of resources. W

Stabilization of evanescent wave propagation operators

This paper presents a stabilized scheme that solves the wave propagation problem in a general bianisotropic, stratified medium. The method utilizes the concept of propagators, i.e., the wave propagation operators that map the total tangential electric and magnetic fields from one plane in the slab to another. The scheme transforms the propagator approach into a scattering matrix form, where a spec

Sagsbehandlerne i forvaltningen skal træffe afgørelser på et oplyst og objektivt grundlag og være i stand til at begrunde afgørelserne. De assisteres dog i stigende grad af beslutningsunderstøttende algoritmer, der er skabt til at generere output fremfor at tilvejebringe en forklaring. Denne udvikling kan effektivisere og for-bedre arbejdsgange, men kan også udfordre forvaltningsretlige krav til s

The Last Urban Frontier : Commodification of Public Space and the Right to the City in Insurgent Hong Kong

Denna avhandling undersöker skapandet och omvandlingen av offentliga platser i Hongkong, en stad som är genomsyrad av nyliberala ideal och som under senare år har kännetecknats av betydande försämringar när det gäller demokratiska rättigheter och friheter. Som ett resultat av den nyliberala kapitalismens expansion har kommodifieringen av det urbana rummet inte bara förvärrats utan också blivit merThis thesis explores the production and transformation of public spaces in Hong Kong, a city that is steeped in neoliberal ideals and has seen substantial deterioration in terms of democratic rights and freedoms in recent years. As a result of the expansion of neoliberal capitalism, commodification of urban space has not only exacerbated, but also become more far-reaching and indiscriminate. While

Adding quark spin effects to PYTHIA string fragmentation

Quark spin effects in hadronization have been recently included in the PYTHIA 8 event generator for the simulation of the deep inelastic scattering (DIS) process off a polarized nucleon target via the external StringSpinner package. The spin effects can be simulated for the production of pseudoscalar mesons using the string+3P0 model of polarized quark fragmentation and parametrizations of the tra

Dark Phase Transition and Gravitational Wave of Strongly Coupled Hidden Sectors

We go beyond the state-of-the-art by combining first principal lattice results and effective field theory approaches as Polyakov Loop model to explore the non-perturbative dark deconfinement-confinement phase transition and the generation of gravitational-waves in a dark Yang-Mills theory. We further include fermions with different representations in the dark sector. Employing the Polyakov-Nambu-J

Detection of Single Charge Trapping Defects in Semiconductor Particles by Evaluating Photon Antibunching in Delayed Photoluminescence

Time-resolved analysis of photon cross-correlation function g(2)(τ) is applied to photoluminescence (PL) of individual submicrometer size MAPbI3 perovskite crystals. Surprisingly, an antibunching effect in the long-living tail of PL is observed, while the prompt PL obeys the photon statistics typical for a classical emitter. We propose that antibunched photons from the PL decay tail originate from

TOTALLY RAMIFIED RATIONAL MAPS

Totally ramified rational maps and regularly ramified rational maps are defined and studied in this paper. We first give a complete classification of regularly ramified rational maps and show that our definition of a regularly ramified rational map is equivalent to a much stronger definition of a map of this kind given by Milnor [Dynamics in one complex variable, Princeton University Press, Prince

Optimizing Species Richness in Mosaic Landscapes : A Probabilistic Model of Species-Area Relationships

Most landscapes are comprised of multiple habitat types differing in the biodiversity they contain. This is certainly true for human modified landscapes, which are often a mix of habitats managed with different intensity, semi-natural habitats and even pristine habitats. To understand fundamental questions of how the composition of such landscapes affects biodiversity conservation, and to evaluate
