The paper gives an overview of the planned orbit correc- tion system for the 3 GeV storage ring at the MAX IV lab- oratory, a light source facility currently under construction in Lund, Sweden[1, 2]. The ring will have a vertical beam size in the 1-4μm range in the insertion device (ID) straight sections depending on coupling[3], which places high re- quirements on the orbit stability. To meet thi

Procedure for the synthesis of decentralized controllers for delayed bilateral teleoperation systems is proposed, based on the analytical solution of a global H2 optimization. Explicit state-space formulae for the optimal controller are presented. The controller possesses a neat structure, which preserves closed-loop stability regardless of the delay length. The behavior of the resulting teleopera

Background/Aims: Thrombocytes have proved to be important for liver regeneration after liver resection in the experimental setting. The aim of our study is to examine the effects of thrombocytes on liver hypertrophy after portal vein embolization (PVE). Methodology: This retrospective cohort study comprised 75 patients with liver metastases from colorectal cancer subjected to PVE in preparation fo

Fishery regulations might not only affect the fleet, but also the relation between fisheries and downstream sectors on the ex-vessel market for fish products. This article estimates the price effects of management reform in the Swedish Baltic Sea cod fishery. In April 2011, as part of a reform process aimed at giving fishers more flexibility, vessels using active gear were given annual non-transfe

In the post-genomic era, it has become evident that genetic changes alone are not sufficient to understand most disease processes including pancreatic cancer. Genome sequencing has revealed a complex set of genetic alterations in pancreatic cancer such as point mutations, chromosomal losses, gene amplifications and telomere shortening that drive cancerous growth through specific signaling pathways

In Frisch grid ionization chambers special attention must be paid to the operating voltages in order to avoid unwanted collection of electrons on the Frisch grid. Collection of electrons on the grid will lead to a decreased signal to noise ratio and consequently a deteriorated energy resolution. Furthermore, systematic errors in the determination of the angular distribution will be introduced. The

Purpose: It is not yet possible to estimate the number of cases required for a beginner to become expert in laparoscopic radical prostatectomy. We estimated the learning curve of laparoscopic radical prostatectomy for positive surgical margins compared to a published learning curve for open radical prostatectomy. Materials and Methods: We reviewed records from 8,544 consecutive patients with prost

A design study of a horizontal neutron reflectometer adapted to the general baseline of the long pulse European Spallation Source (ESS) is presented. The instrument layout comprises advanced solutions for the neutron guide, high-resolution pulse shaping and beam bending onto a sample surface being thoroughly adjusted to the properties of the ESS. The length of this instrument is roughly 55 m, enab

OBJECTIVE-To develop a model for the prediction of type 2 diabetes mellitus (T2DM) risk on the basis of a multivariate logistic model and 1-h plasma glucose concentration (1-h PG). RESEARCH DESIGN AND METHODS-The model was developed in a cohort of 1,562 non-diabetic subjects from the San Antonio Heart Study (SAHS) and validated in 2,395 nondiabetic subjects in the Botnia Study. A risk score on the

Poly-3-d-hydroxybutyrate (PHB) is a promising biopolymer naturally produced by several bacterial species. In the present study, the robust baker's yeast Saccharomyces cerevisiae was engineered to produce PHB from xylose, the main pentose found in lignocellulosic biomass. The PHB pathway genes from the well-characterized PHB producer Cupriavidus necator were introduced in recombinant S. cerevisiae

We present an electrode, based on structurally controlled nanowires, as a first step towards developing a useful nanostructured device for neurophysiological measurements in vivo. The sensing part of the electrode is made of a metal film deposited on top of an array of epitaxially grown gallium phosphide nanowires. We achieved the first functional testing of the nanowire-based electrode by perform

In this paper, we present a controller synthesis algorithm for a decentralized control problem. We consider an architecture in which there are two interconnected linear subsystems. Both controllers seek to optimize a global quadratic cost, despite having access to different subsets of the available measurements. Many special cases of this problem have previously been solved, most notably the state

Interest in high spatial resolution boron analyses from a geochemical perspective is related to the recognition of boron as an important tracer of chemical recycling in the Earth, due to the high solubility of boron in aqueous fluids and silicate melts. Although boron is not a nominal component in common silicates they may still contain significant B-concentrations and hence constitute important b
