Effective-interaction approach to the many-boson problem

We show that the convergence behavior of the many-body numerical diagonalization scheme for strongly interacting bosons in a trap can be significantly improved by the Lee-Suzuki method adapted from nuclear physics: One can construct an effective interaction that acts in a space much smaller than the original Hilbert space. In particular for short-ranged forces and strong correlations, the method o

Lithostratigraphy of the Late Saalian to Middle Weichselian Skaerumhede Group in Vendsyssel, northern Denmark

The Quaternary sedimentary succession in Vendsyssel, northern Denmark, contains a unique, high-resolution record of the last interglacial and glacial periods. There is still much debate, however, about the timing and ice extent in this southwestern part of the Scandinavian Ice Sheet, particularly during the Middle Weichselian. In this study, a detailed lithostratigraphical subdivision is establish

Survival after initial hospitalisation for heart failure: a multilevel analysis of patients in Swedish acute care hospitals

STUDY OBJECTIVE: Although national variation in short-term prognosis (that is, 30 day mortality) after a patients first hospitalisation for heart failure may depend on individual differences between patients, dissimilarities in hospital practices may also influence prognosis. This study, therefore, sought to disentangle patient determinants from institutional factors that might explain such variat

Nile blue adsorbed onto silica gel modified with niobium oxide for electrocatalytic oxidation of NADH

A study of modified carbon paste electrode employing Nile blue (NB) adsorbed on silica gel modified with niobium oxide (SN) for electrocatalytic oxidation of reduced nicotinamide adenine dinucleotide (NADH) is described. The adsorbed organic dye on SN was used to prepare a modified carbon paste electrode to investigate its electrochemical properties. The formal potential (E-o') of the adsorbed NB

The social life and attitudes of 80 year olds in Iceland and Sweden - A comparison of two city populations

The 80+ Studies are collecting longitudinal data regarding medical, psychological, and sociological aspects of 80-year-old people in Lund, Sweden and Reykjavik, Iceland. Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher

Families' lived experience one year after a child was diagnosed with type 1 diabetes

Aim. This paper is a report of a study to elucidate families' lived experience of diabetes one year after a child was diagnosed with type 1 diabetes. Background. The incidence of type 1 diabetes is rapidly increasing worldwide, with a shift towards younger age groups. This illness is treated by means of an intensive management regimen that often disrupts the child's usual activities and requires d

Models of compact simple Kantor triple systems defined on a class of structurable algebras of skew-dimension one

Let $(A,^-):={\cal M}(J)$ be the $2 \times 2$-matrix algebra determined by Jordan algebra $J:=H_3(\mathbb{A})$ of hermitian $3 \times 3$-matrices over a real composition algebra $\mathbb{A}$, where $(A,^-)$ is the standard involution on $A$. We show that the triple systems $B_A(x,\overline{y}^\sim,z), x,y,z\in\mathbb{A}$, are models of simple compact Kantor triple systems satisfying the condition

Excited Bands in Fixed CNS Configurations

Exact and approximate quantum numbers of the cranked Nilsson-Strutinsky (CNS) formalism are exploited to calculate excited bands in fixed configurations with the energy of the individual bands minimized with respect to deformation for all spin values. The formalism is illustrated to calculate all bands which appear important in the decay out of the superdeformed band in 59Cu

OARSI recommendations for the management of hip and knee osteoarthritis, part I: critical appraisal of existing treatment guidelines and systematic review of current research evidence

PURPOSE: As a prelude to developing updated, evidence-based, international consensus recommendations for the management of hip and knee osteoarthritis (OA), the Osteoarthritis Research Society International (OARSI) Treatment Guidelines Committee undertook a critical appraisal of published guidelines and a systematic review (SR) of more recent evidence for relevant therapies. METHODS: Sixteen exper

Metabolic syndrome, plasma lipid, lipoprotein and glucose levels, and endometrial cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC)

To clarify the role of metabolic factors in endometrial carcinogenesis, we conducted a case-control study nested within the European Prospective Investigation into Cancer and Nutrition (EPIC), and examined the relation between prediagnostic plasma lipids, lipoproteins, and glucose, the metabolic syndrome (MetS; a cluster of metabolic factors) and endometrial cancer risk. Among pre- and postmenopau

Sensor Fusion for Compliant Robot Motion Control

Force feedback control is necessary for accurate force control in robotic manipulators and, thus far, wrist force/torque (F/T) sensors have been used. An important problem arises when only these types of sensors are used. In a dynamic situation where the manipulator moves in either free or constrained space, the interaction forces and moments at the contact point and also the non-contact ones are

Immunostaining for p16(INK4a) used as a conjunctive tool improves interobserver agreement of the histologic diagnosis of cervical intraepithelial neoplasia

The quality of cervical histopathology is critical to cervical cancer prevention, cancer treatment, and research programs. On the basis of the histology results further patient management is determined. However, the diagnostic interpretation of histologic hematoxylin-eosin (H&E)-stained slides is affected by substantial rates of discordance among pathologists. Overexpression of the cyclin-depe

The phenotype in Norwegian patients with Bardet-Biedl syndrome with mutations in the BBS4 gene

Objective: To describe the phenotype of the Bardet-Biedl syndrome in patients with mutations in the BBS4 gene. Methods: We examined 3 pairs of siblings with Bardet-Biedl syndrome in whom 3 different mutations in the BBS4 gene were detected, 2 of which were homozygous for the mutation. Results: All patients had an increased body mass index. The obesity varied between families from moderate to sever

Effect of riparian structure, temperature and channel morphometry on detritus processing in channelized and natural woodland streams in southern Sweden

1. Ten south Swedish streams were selected to represent two distinct types - natural woodland streams and channelized streams. Measurements were made on leaching, decomposition and microbial respiration of the dominant riparian vegetation (European Black Alder), structure of the benthic macroinvertebrate community, macroinvertebrates inhabiting leaf material, channel morphometry, macrophyte compos

Boards of directors and entrepreneurial posture in medium-size companies: Putting the board demography approach to a test

A growing body of research suggests that a strong and vigilant board can have a significant influence on the value-creating potential of medium-size companies by favouring change and innovation in strategic decision-making. Yet how best to conceptualize this relationship remains controversial in scholarly circles. The mainstream approach has been to argue for a direct relationship between board de

Monte Carlo simulation of the photoneutron field in linac radiotherapy treatments with different collimation systems

Bremsstrahlung photon beams produced by linac accelerators are currently the most commonly used method of radiotherapy for tumour treatments. When the photon energy exceeds 10 MeV the patient receives an undesired dose due to photoneutron production in the accelerator head. In the last few decades, new sophisticated techniques such as multileaf collimators have been used for a better definition of
