Biocompatible chemically cross-linked organic-inorganic (O-I) hybrid nanocomposites were developed using a new atoxic, simple and fast, solvent-free pathway. Poly(ϵ-caprolactone) (PCL) and poly(ethylene glycol) (PEG), which are both biocompatible, were used as the organic moieties (at different PCL/PEG ratios), while in situ synthesized polysilsesquioxanes made up the inorganic moiety. The O-I hyb

Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, and thus control mechanical anisotropy of the cell wall. Here we analyze how, in turn, cell shape may influence microtubule behavior. Buidling upon previous models that confined m

Fashion is a social phenomenon par excellence. A simple sociological definition of fashion is 'being first with the latest.' Its underlying principle is revealed in the link between the modus derivatives and the term 'modern,' with its original meaning of 'now' or 'for today.' Fashion revolves around imitation and diffusion, and it applies to all domains of social life, though most of the research

Background: Secondary hyperparathyroidism and altered levels of parathyroid hormone (PTH) are associated with vascular events in chronic kidney disease. After renal transplantation, this association is not clear. Pre-transplant parathyroidectomy (PTX) is common, but post-transplant data are scarce. We aimed to study the effect of PTH at the time of transplantation on risk of post-transplant vascul

This paper deals with noise suppression in multichannel measurements, using a certain signal model but without assuming stationarity of the signals involved. This enables application to signals whose spectral characteristics are time-variable. The novelty consists of an algorithm for obtaining an approximation of the Wiener filter for each channel. The filters are computed using the Weyl transform

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease. Anti-citrullinated protein antibodies (ACPA) are crucial for the serological diagnosis of RA, where Epstein-Barr virus (EBV) has been suggested to be an environmental agent in triggering the onset of the disease. This study aimed to analyse antibody reactivity to citrullinated EBV nuclear antigen-2 (EBNA-2) peptides from three dif

We address the problem of detecting double-talk in a full duplex transmission line. A new double-talk detector (DTD) based on measuring the similarity between the far- and near-end speech signals is proposed. The detector is block oriented and operates in the frequency domain where the similarity between the signals is measured by means of the coherence function. The coherence is estimated with a

Introduction: The importance of mobile health has increased during recent years but few studies have described the use of apps among persons with neurological disabilities. Aim: The aim of this paper was to describe how persons ageing with a neurological disability experience barriers and facilitators in relation to using apps in everyday life. Method: A qualitative approach was used. 16 persons w

A physical network node controls allocation and/or deallocation of resources of an interconnected hardware infrastructure. The physical network node determines a number of requests currently queued at a first service node of a plurality of serially-connected service nodes at a current time. The plurality of serially-connected service nodes supports a packet flow using resources of the interconnect

The question of what makes ‘Nordic’ music distinctive is a matter of some dispute. Does it exist? Or, in what ways is it able to manifest itself? Like nationality, it is a construction of identity that emerges through discourses on music and on Nordicness. Essentially it is an open signifier, as concepts of Nordicness can be identified either with something dark, cold and obscure or as something r

Since N. v. the United Kingdom, an exceptionally high threshold has been applied to migrants who try to avoid expulsion in order to continue to receive medical assistance in the returning state. With Paposhvili v. Belgium, the Grand Chamber of the ECtHR recognized the ensuing protection gap and modified the standards. These modifications imply a small opening of the ‘very exceptional’ standard to

The main objective was to estimate the frequency of early vascular aging (EVA) in a sample of subjects from Latin America, with emphasis in young adults. We included 1416 subjects from 12 countries in Latin America who provided information about lifestyle, cardiovascular risk factors (CVRF), and anthropometrics. We measured pulse wave velocity (PWV) as a marker of arterial stiffness, and blood pre

Background: Elderly persons with a dementia diagnosis often suffer from different neuropsychiatric symptoms (NPS) such as delusions, hallucinations, depression, anxiety, irritability and agitation. Currently, the medical treatment for NPS consists mostly of psychotropic medication such as hypnotics/sedatives, anxiolytics and antipsychotics. In elderly persons with dementia, usage of antipsychotics

The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. The system studied is a two-echelon system with one central warehouse and a number of local sites,The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures.
