Performance of jet substructure techniques for large-R jets in proton-proton collisions at root s=7 TeV using the ATLAS detector

This paper presents the application of a variety of techniques to study jet substructure. The performance of various modified jet algorithms, or jet grooming techniques, for several jet types and event topologies is investigated for jets with transverse momentum larger than 300 GeV. Properties of jets subjected to the mass-drop filtering, trimming, and pruning algorithms are found to have a reduce

Optimal View Path Planning for Visual SLAM

In experimental design and 3D reconstruction it is desirable to minimize the number of observations required to reach a prescribed estimation accuracy. Many approaches in the literature attempt to find the next best view from which to measure, and iterate this procedure. This paper discusses a continuous optimization method for finding a whole set of future imaging locations which minimize the rec

Comparing Health Outcomes and Costs of General Vaccination with Pneumococcal Conjugate Vaccines in Sweden: A Markov Model

Background: Two new pneumococcal conjugate vaccines were licensed to immunize infants and young children against pneumococcal disease. Objectives: The objective of this study was to estimate the expected health benefits, costs, and incremental cost-effectiveness of routine vaccination with the 10-valent pneumococcal nontypeable hemophilus influenza protein-D conjugate vaccine (PHiD-CV) compared wi

Starting-Condition Dependence of Order Parameters Derived from Molecular Dynamics Simulations

We have studied how backbone N-H S-2 order parameters calculated from molecular dynamics simulations depend on the method used to calculate them, the starting conditions, and the length of the simulations. Using the carbohydrate binding domain of galectin-3 in the free and lactose-bound states as a test case, we compared the calculated order parameters with experimental data from NMR relaxation. T

A controlled study of consumption of beta-glucan-enriched soups for 2 months by type 2 diabetic free-living subjects

Type 2 diabetes is associated with a higher cardiovascular risk and there has been a growing interest in using dietary intervention to improve lipid profile and glucose control. The present work aims at analysing the effects of the enrichment of a normal diet with beta-glucan (3-5 g/d) in free-living type 2 diabetic subjects for 2 months, using a palatable soup. This trial was a parallel, placebo-

TURBT Can Cause Seeding of Cancer Cells into the Bloodstream.

TURBT is the initial diagnostic procedure in bladder cancer (BC). Hypothetically, tumor resection could induce seeding of cancer cells into the circulation and subsequent metastatic disease. The objective of this study was to ascertain whether TURBT induces measurable seeding of cancer cells into the vascular system.

Association between CD8(+) T cell subsets and cardiovascular disease.

OBJECTIVES: The findings of experimental studies suggest that the immune system plays a key role in atherosclerosis but the clinical importance of different immune cells in cardiovascular disease remains poorly characterized. In this study we investigated the association between CD8(+) T cells and carotid disease as well as development of cardiovascular disease events. DESIGN: The study cohort com

DNA in nanochannels-directly visualizing genomic information

The power of nanofluidic channels to analyze DNA is described along with practical experimental hints. As an introduction, a general overview is given on conventional DNA analysis tools, as well as tools under development towards the $1000 genome. The focus of this tutorial review is the stretching of DNA in nanoscale channels for coarse-grained mapping of DNA. To understand the behavior of the DN

Body iron status and gastric cancer risk in the EURGAST study.

Although it appears biologically plausible for iron to be associated with gastric carcinogenesis, the evidence is insufficient to lead to any conclusions. To further investigate the relationship between body iron status and gastric cancer risk, we conducted a nested case-control study in the multicentric European Prospective Investigation into Cancer and Nutrition (EPIC) study. The study included

Familial risk of sleep-disordered breathing

Objective: To estimate the incidence of hospitalization for paediatric obstructive sleep apnoea syndrome (OSAS) or sleep-disordered breathing (SDB) caused by adenotonsillar or tonsillar hypertrophy without infection in children with a parent affected by OSAS. Patients and methods: Using the MigMed database at Lund University, hospital data on all children aged 0-18 years in Sweden between 1997 and

The Target for Statins, HMG-CoA Reductase, Is Expressed in Ductal Carcinoma-In Situ and May Predict Patient Response to Radiotherapy.

Patients with ductal carcinoma-in-situ (DCIS) are currently not prescribed adjuvant systemic treatment after surgery and radiotherapy. Prediction of DCIS patients who would benefit from radiotherapy is warranted. Statins have been suggested to exert radio-sensitizing effects. The target for cholesterol-lowering statins is HMG-CoA reductase (HMGCR), the rate-limiting enzyme in the mevalonate pathwa

Association between DRD4 gene polymorphism and personality variation in great tits: a test across four wild populations

Polymorphisms in the dopamine receptor D4 gene (DRD4) have been related to individual variation in novelty-seeking or exploratory behaviour in a variety of animals, including humans. Recently, the human DRD4 orthologue was sequenced in a wild bird, the great tit (Parus major) and a single nucleotide polymorphism in exon 3 of this gene (SNP830) was shown to be associated with variation in explorato

Structure and Characterization of KSc(BH4)(4)

A new potassium scandium borohydride, KSc(BH4)(4), is presented and characterized by a combination of in situ synchrotron radiation powder X-ray diffraction, thermal analysis, and vibrational and NMR spectroscopy. The title compound, KSc(BH4)(4), forms at ambient conditions in ball milled mixtures of potassium borohydride and ScCl3 together with a new ternary chloride K3ScCl6, which is also struct

A Real-Time Decision Rule for an Inventory System with Committed Service Time and Emergency Orders

n this paper, we study the inventory system of an online retailer with compound Poisson demand. The retailer normally replenishes its inventory according to a continuous review (nQ, R) policy with a constant lead time. Usually demands that cannot be satisfied immediately are backordered. We also assume that the customers will accept a reasonable waiting time after they have placed their orders bec

Symmetrical and unsymmetrical short-circuit current of squirrel-cage and doubly-fed induction generators

A general method for calculating the short-circuit currents of a squirrel-cage (SCIG) and a doubly fed induction generator (DFIG) using crowbar protection is presented. The method results in an approximate analytic expression that allows calculating the SCIG and DFIG short-circuit currents as a function of time for symmetrical and unsymmetrical faults in the power system. The presented theoretical
