We examine the near-field optical properties of multilayered metal core-shell sphere nanostructures by extending the Mie theory, and demonstrate that the local-field enhancement can be increased by adding new metal shells. A local intensity enhancement of more than 10(5) times can be obtained in the cavity between the Ag core and the innermost Ag shell for proper configurations of multilayered Ag
The Oxford-12 Item Knee Score is a recently developed and validated patient-completed outcome measure designed specifically for use with knee arthroplasty in the United Kingdom. We have translated this questionnaire into Swedish and tested the validity and reliability of the translated version in a cross-sectional study by a postal survey to 1,200 randomly selected patients from the Swedish Knee A
Iterative numerical schemes for solving the electrostatic partial differential equation with variable conductivity, using fast and high-order accurate direct methods for preconditioning, are compared. Two integral method schemes of this type, based on previously suggested splittings of the equation, are proposed, analyzed, and implemented. The schemes are tested for large problems on a square. Par
In this paper we investigate the structure and motion problem for calibrated one-dimensional projections of a two-dimensional environment. The theory of one-dimensional cameras are useful in several areas, e.g. within robotics, autonomous guided vehicles, projection of lines in ordinary vision and vision of vehicles undergoing so called planar motion. In a previous paper the structure and motion p
Adaptive estimation of the linear coefficient vector in truncated expansions is considered for the purpose of modeling noisy, recurrent signals. Two different criteria are studied for block-wise processing of the signal: the mean square error (MSE) and the least squares (LS) error. The block LMS (BLMS) algorithm, being the solution of the steepest descent strategy for minimizing the MSE, is shown
OBJECTIVES: To replicate the relation between the CSF HVA:5-HIAA ratio and psychopathic traits previously reported in a pilot group of 22 perpetrators of violent crimes. METHODS: CSF monoamine metabolite concentrations in another 28 violent and sexual offenders, aged 45 or below, referred to pretrial forensic psychiatric investigation, were compared to features of psychopathy according to the Psyc
The present study evaluated the combination of antithymocyte globulin (ATG) and cyclosporine A (CsA) in patients with low-risk myelodysplastic syndromes. Twenty patients (17 with refractory anemia and 3 with refractory anemia with excess blasts) received treatment with rabbit-ATG plus CsA. The overall response rate was 30% (6/20); three of the six responders had a complete response. The responses
The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow upsilon(2)(eta)), as determined recently by the PHOBOS experiment for Au + Au collisions at root(S)NN = 130 and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of upsi
Laser-induced fluorescence (LIF) has been developed for visualization of fuel distribution fields in an operating spark-ignition (SI) engine. Since the standard research fuel iso-octane, does not yield a useful LIF signal a fluorescent additive was used. None of the commonly used seeds were found adequate. A seed not commonly used in this context, 3-pentanone, C2H5COC2H5, was chosen due to favorab
An axillary brachial plexus nerve block by a transarterial approach is commonly used to achieve regional anaesthesia for hand surgery. We designed a retrospective study to evaluate efficacy and safety of the technique for acute and elective operations. Anaesthetic records of 189 of all 5520 patients (1996-2000) who had axillary brachial plexus blocks for hand surgery were reviewed, and results com
Pancreatic cancer is strongly associated with the development of hyperglycemia, peripheral insulin resistance and diabetes mellitus, especially when presented as new-onset diabetes mellitus. Peripheral insulin resistance and hyperinsulinemia have been suggested to promote growth of pancreatic cancer cells, and therefore a relation between long-standing diabetes mellitus type 2 and pancreatic cance
Epidemiological studies have shown an increased incidence of cancer among workers occupationally exposed to polycyclic aromatic hydrocarbons (PAHs). As the dermal route is considered important for exposure to PAHs in the workplace, the aim of this study was to develop and evaluate a tape-stripping technique for monitoring dermal exposure to pyrene and benzo(a)pyrene. The tape-stripping method was
Alliances are volatile key components of many corporations' competitive strategies. They offer fast and flexible means of achieving market access, scale economies, and competence development. However, strategic alliances can encounter difficulties that often lead to disappointing performance. The authors suggest that the way partners manage the collective learning process plays a central role in t
This paper aims to portray the increasingly complex normative structure of international climate change regime, which consists of the 1992 UN Framework Convention on Cimate Change, the 1997 Kyoto Protocol as well as other additional elements that playing a role, such as the practices of the Intergovernmental Panel on Climate Change and the Global Environmental Facility and procedures of these inst
