We use the frequency doubled light from an optically trapped lithium niobate particle for non-intrusive scanning near-field optical microscopy. The detected power from this 50-100 nm diameter probe is currently tens of pW and is expected to approach nW with an improved detection system. The current experimental resolution is approximately 0.5 [mu]m, while the ultimate theoretical resolution is 70-
Background: Clinical studies have evaluated a correlation between preoperative walking capacity or function and outcome after hip and knee joint replacement surgery with contradictory results. Our aim was to investigate the effect of preoperative metabolic and/or aerobic exercise on surgical outcome, as well as to evaluate the effect of cumulated exercise by using a cutoff value at 3.5 hours throu
This study provides empirical evidence for long memory in the volatility process of VIX futures returns and investigates the practical importance of modelling it when calculating Value-at-Risk (VaR) for VIX futures and pricing VIX options. The analysis is performed using the GARCH, APARCH, FIGARCH and FIAPARCH models with the normal and skewed Student-t distributions. The VaR analysis shows that t
Abstract in FrenchDecay-prediction models can be used to predict the service life of wooden components. However, knowledge of how the material climate, i.e. moisture content and material temperature, varies with time is required. A reliable material climate prediction model is therefore crucial in situations when measurements are not viable. The aim of this paper is to develop and assess the perfo
In recent decades, the effects of religious pluralism on religious participation has been a much debated topic among sociologists of religion. During most of the 20th century, the traditional view among sociologists was that pluralism undermines religion because competition between religious organizations was assumed to impair the credibility of religion as such. In the 1980s, however, this view w
Respiratory symptoms among hairdressers are often ascribed to the use of bleaching powders that contain persulfate salts. Such salts can act as allergens and airway irritants but the mechanisms behind the negative health effects are not fully known. In order to understand why some hairdressers experience respiratory symptoms during, and after, sessions of hair bleaching, it is of importance to cha

Neurotensin regulates both satiety and breast cancer growth in the experimental setting, but little is known about its role in the development of breast cancer or cardiometabolic disease in humans.
Several efficient counters are presented. A nine-transistor divide-by-two circuit is used as a basic building block. With transistor sizing, an input frequency of 400 MHz can be adopted by an asynchronous counter, while an eight-bit synchronous counter can achieve clock rates of more than 200 MHz in a 3-μm CMOS process. The power consumption of the proposed precharged dynamic synchronous counter i
Bruton's tyrosine kinase (Btk) is encoded by the gene that when mutated causes the primary immunodeficiency disease X-linked agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (Xid) in mice. Btk is a member of the Tec family of protein tyrosine kinases (PTKs) and plays a vital, but diverse, modulatory role in many cellular processes. Mutations affecting Btk block B-lymphocyte develop
