Empirical-bias bandwidths for spatial local polynomial regression with correlated errors

The empirical-bias bandwidth selector (EBBS) is a method for data-driven selection of bandwidths for local polynomial regression. It is a bandwidth selection method for estimation of the mean-function and its partial derivatives of any order as well as for estimation of the variance-function. Moreover EBBS allows for univariate as well as multivariate predictor variables. In this paper we introd

Exploring Processor and Memory Architectures for Multimedia

Popular Abstract in English Consumption of multimedia content is one of the main tasks we perform in our day-to- day lives, such as listening to music on an iPod or watching the news from an online steaming service. As technology has evolved and enabled easier access to different content (basically access anything anywhere), our consumption has grown. In only the last decades we have evolved from Multimedia has become one of the cornerstones of our 21st century society and, when combined with mobility, has enabled a tremendous evolution of our society. However, joining these two concepts introduces many technical challenges. These range from having sufficient performance for handling multimedia content to having the battery stamina for acceptable mobile usage. When taking a projection of w

Isolation of photoreceptors in the cultured full-thickness fetal rat retina.

Purpose. To create a retina consisting mainly of photoreceptors for future use as donor tissue in retinal transplantation. Methods. Fetal full-thickness neuroretinas from Sprague Dawley rats 17 (E17) or 20 (E20) days post conception were placed in culture for 7 or 14 days. Explants and age-matched control retinas were examined by light microscopy and with a panel of immunohistochemical markers lab

Comparison of responses to vasoactive drugs in human and rat cerebral arteries using myography and pressurized cerebral artery method.

Background:Dilatation of cranial vessels has been proposed as a part of the cascade that initiates an episode of migraine. This is based on the observation that intravenous administration of several substances with vasodilator properties can trigger migraine-like symptoms in migraineurs.Methods:We used in vitro myography of human cerebral arteries and in vitro pressurized arteriography of rat midd

Training and bone - from health to injury.

Mechanical load through physical activity has been shown to be one of the best stimuli to increase the bone strength. This effect of mechanical load accounts for both the accrual of bone mineral and structural skeletal adaptations. Exercise prescription also includes a "window of opportunity" in the late pre- and early peri-pubertal period, where exercise is supposed to insert the most obvious ben

Informationsutbyte i internationellt myndighetssamarbete – e-förvaltning, sekretess och personuppgiftsskydd i Försäkringskassans samverkan med utländska socialförsäkringsorgan

Genom EU-rätten och Sveriges konventioner om social trygghet ingår Försäkringskassan och andra svenska socialförsäkringsorgan i internationella administrativa samarbetsstrukturer. I dessa utbyts uppgifter om enskilda i fråga om exempelvis namn, familjeförhållanden och hälsotillstånd. I artikeln undersöks hur Försäkringskassan ska delta i sådant informationsutbyte och samtidigt tillämpa den svenska

Gastrointestinal cancer among cement workers. A case-referent study

A matched case-referent study was conducted to investigate the risk of gastrointestinal cancer in cement workers. All male cases of cancer in esophagus, stomach, colon and rectum in the period 1922-1988 from two parishes surrounding a cement plant were identified. For each case, four referents were chosen, matched to age and year of death. Employment in the cement plant was confirmed as from plant

Methods and Tools for Co-Simulation of Dynamic Systems with the Functional Mock-up Interface

Popular Abstract in Swedish Utveckling av nya industriella produkter sker allt oftare med hjälp av datormodeller. Dessa modeller beskriver fysiken för respektive produkt, vilket exempelvis kan vara en bil eller ett kraftverk. Med hjälp av modellerna kan en stor del av analyserna på de framtida produkterna ske med hjälp av datorer, varför färre prototyper behöver konstrueras, vilket medför kortare Simulation of coupled dynamical systems, where the subsystems are bundled with their own internal solver, is important in industry. This is due to that in many cases, with complex systems, this is the only viable option. In this setting, the dynamics of each system is hidden and information between subsystems is exchanged through sampled inputs and outputs, a weakly coupled system. While a new ind
