We study membership in Lipschitz classes (Formula presented.) for a class of α-harmonic functions in the open unit disc (Formula presented.) in the complex plane. From earlier work by Olofsson and Wittsten we know that such an α-harmonic function u is the α-harmonic Poisson integral (Formula presented.) of its boundary value function f on the unit circle (Formula presented.). We determine when the
Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. The most potent toughening mechanisms arise at the microscale when cracks interact with the osteonal microstructure and deflect along weak interfaces.
Rotavirus (RV) infections remain the leading cause of world-wide diarrhea-associated morbidity and mortality among children <5 years of age. Despite the global introduction of RV vaccines over a decade ago, RV infections result in >200,000 deaths annually mostly in the low-income countries of Africa and Asia. Efficient clearance of the primary RV infection and protection from future re-infections
In vehicular communications systems the channel estimation filter suppresses the additive noise in channel estimates obtained from pilot symbols. Vehicular channels show local stationarity for a finite region in time and frequency, only. Such a process can be divided into consecutive stationarity regions, allowing to calculate a Wiener filter. We analyze the increase of the mean square error (MSE)
This study attempts to apply computational methods to the Twitter Election Integrity Datasets in order to derive a basic descriptive overview of this disinformation data, and to suggest some possible routes for developing these methods to address future research questions. The results indicate substantial variations in tweet frequency over time and geographical regions, as well as differences in r
Taking a deep look at how China has transformed its capacity for scientific research and innovation provides a window into the country’s ambitions and possible paths in the future.
In this article, we consider the properties of the Pesaran CD test for cross-section correlation when applied to residuals obtained from panel data models with many estimated parameters. We show that the presence of period-specific parameters leads the CD test statistic to diverge as the time dimension of the sample grows. This result holds even if cross-section dependence is correctly accounted f
This paper presents research on the need for boundary spanners in organizations that has an offshore insourcing strategy for the IT-function. The research question addressed was: How does an offshore insourcing strategy influence the need for having boundary spanners? Empirical data was collected using a case study in three phases, including semi-structured and structured interview in a multinatio
Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics and photocatalysis. The ease with which metal-halide perovskites can be synthesized in the form of brightly luminescent colloidal nanocrystals, as well as their tunable an
No-go decay (NGD) targets mRNAs with stalls in translation elongation for endonucleolytic cleavage in a process involving the Dom34 and Hbs1 proteins. The crystal structure of a Schizosaccharomyces pombe Dom34-Hbs1 complex reveals an overall shape similar to that of eRF1-eRF3-GTP and EF-Tu-tRNA-GDPNP. Similarly to eRF1 and GTP binding to eRF3, Dom34 and GTP bind to Hbs1 with strong cooperativity,
Emerging data indicates SGRT could improve safety and quality by preventing errors in its capacity as an independent system in the treatment room. The aim of this work is to investigate the utility of SGRT in the context of safety and quality. Three incident learning systems (ILS) were reviewed to categorize and quantify errors that could have been prevented with SGRT: SAFRON (International Atomic
Bacterial endotoxin is a potent inflammatory antigen abundant in the human intestine. Endotoxins circulate in the blood at low concentrations in all healthy individuals. Elevated levels of circulatory endotoxins may cause inflammation with the development of chronic disease, either affecting metabolism, neurological disease, or resistance to viral and bacterial infections. The most important endot
In order to reduce maritime transportation's greenhouse gas and pollutant emissions, marine engine manufacturers need to deepen the fundamental understanding of the injection and spray process. Two-dimensional unsteady-state Reynolds-averaged Navier-Stokes simulations were conducted to investigate evaporating high-pressure marine engine sprays, in which an injector with a nozzle diameter of 0.44 m
Osteoarthritis (OA) remains the most challenging arthritic disorder, with a high burden of disease and no available disease-modifying treatments. Symptomatic early-stage OA of the knee (the focus of this Review) urgently needs to be identified and defined, as efficient early-stage case finding and diagnosis in primary care would enable health-care providers to proactively and substantially reduce
We approach critically the assertion that a referendum ultimately defends the “traditional family,” by examining the articulation of anti-gender politics in Romanian parliamentary debates. We contribute theoretically by employing the concept of retrogressive mobilization in plebiscitary circumstances. We show that in Romania the contours of retrogressive mobilization transgress both the ideologica
Human rely profoundly on tactile feedback from fingertips to interact with the environment, whereas most hand prostheses used in clinics provide no tactile feedback. In this study we demonstrate the feasibility to use a tactile display glove that can be worn by a unilateral hand amputee on the remaining healthy hand to display tactile feedback from a hand prosthesis. The main benefit is that users
In an ampoule for a medicament the space accommodating the medicament is defined by an ampoule wall (1) a pierceable seal (5) closing one end of the ampoule and a piston (7) closing the other end of the ampoule. A metal containing fixation element (8) is secured to one of the parts defining the medicament accommodating space. A mixing element (9, 10) also containing a metal and having a density la
