An adaptive filter model of cerebellar zone C3 as a basis for safe limb control?

The review asks how the adaptive filter model of the cerebellum might be relevant to experimental work on zone C3, one of the most extensively studied regions of cerebellar cortex. As far as features of the cerebellar microcircuit are concerned, the model appears to fit very well with electrophysiological discoveries concerning the importance of molecular layer interneurons and their plasticity, t

InSb Nanowire Field-Effect Transistors and Quantum-Dot Devices

The authors present fabrication and electrical measurements of InSb nanowire field-effect transistors (FETs) and quantum dots. The devices are made on a SiO2-capped Si substrate from InSb segments of InAs/InSb heterostructured nanowires, which are grown by metalorganic vapor phase epitaxy. For the FETs, both single- and dual-gate devices are fabricated. The Si substrate is employed as the back gat

Supply chain management integration: a critical analysis

Purpose The purpose is to examine various aspects of integration in order to structure and define the concept of supply chain management integration. Design/methodology/approach The study is based on an extensive literature review in three steps and a series of interviews with leading SCM consulting firms. Findings We found limited empirical research discussing SCM integration beyond the dyadi

External or internal fixation in the treatment of non-reducible distal radial fractures? A 5-year follow-up of a randomized study involving 50 patients

Background and purpose We have previously shown in a randomized study that in the first year after treatment, open reduction and internal fixation resulted in better grip strength and forearm rotation than closed reduction and bridging external fixation. In the present study, we investigated whether this difference persists over time. Patients and methods The 50 patients included in the original s

Generalization of the classical xyz-polarization analysis technique to out-of-plane and inelastic scattering

The technique of longitudinal ("xyz") polarization analysis has been used successfully for many years to study disordered magnetic materials in thermal and cold neutron diffraction experiments. The technique allows the simultaneous and unambiguous separation of the nuclear, magnetic, and nuclear spin-incoherent contributions to the scattering. The technical advances seen in recent years, such as t

Seroepidemiology of sexually transmitted infections of prostate cancer

Background: There has been substantial progress in epidemiological research on prostate cancer over the last decade. An area of increasing interest is the possible role of sexual activity and history of sexually transmitted infections as a risk factor for prostate cancer. Specific sexually transmitted infections have only inconsistently been associated with prostate cancer, with positive associati

Examestane in advanced or recurrent endometrial carcinoma: a prospective phase II study by the Nordic Society of Gynecologic Oncology (NSGO)

Background: We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. Methods: We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estro

Quarrying for Claudius, protected by Min: Reflections on a small quarry in Gebel el Silsila East

Until now inscriptions have confirmed that the quarries of Gebel el Silsila East were in use until the time of Emperor Tiberius, but recent findings indicate that the quarrying process continued for at least another two generations. In one of the many smaller quarries three men carved their name repeatedly on the quarry walls, and dated their visits to a four year period, between the sixth and ten

Increased survival with mechanical ventilation in post-tuberculosis patients with the combination of respiratory failure and chest wall deformity

Background Patients who have suffered from tuberculosis are at risk of respiratory failure with hypercapnea from chest wall deformity and hypoxia from pulmonary sequelae. The combination of hypercapnea and hypoxia justifies both mechanical ventilation and oxygen therapy as treatment options. We aimed to study which treatment mode is associated with the best survival in patients with the combinatio

A fully coupled thermomechanical two-dimensional simulation model for orthogonal cutting: formulation and simulation

In this paper a fully coupled thermomechanical two-dimensional simulation model for orthogonal cutting is presented. The model is based on the arbitrary Lagrangian-Eulerian formulation with the remeshing technique. The material model used for the workpiece material includes Johnson-Cook plasticity, and as the chip separation criterion the Johnson-Cook damage law is employed. The different friction

General solution for quantitative dark-field contrast imaging with grating interferometers.

Grating interferometer based imaging with X-rays and neutrons has proven to hold huge potential for applications in key research fields conveying biology and medicine as well as engineering and magnetism, respectively. The thereby amenable dark-field imaging modality implied the promise to access structural information beyond reach of direct spatial resolution. However, only here a yet missing app

Adolescents' Lifetime Experience of Selling Sex: Development Over Five Years

Lifetime experience of selling sex among adolescents was investigated together with sociodemographic correlates, parentchild relationship, and the existence of people to confide in. Changes over time regarding the selling of sex were investigated through a comparison of data from 2004 and 2009. This study was carried out using 3,498 adolescents from a representative sample of Swedish high school s

Variant in the glucokinase regulatory protein (GCKR) gene is associated with fatty liver in obese children and adolescents

Recently, the single nucleotide polymorphism (SNP) identified as rs1260326, in the glucokinase regulatory protein (GCKR), was associated with hypertriglyceridemia in adults. Because accumulation of triglycerides in hepatocytes represents the hallmark of steatosis, we aimed to investigate whether this variant might be associated with fatty liver (hepatic fat content, HFF%). Moreover, because recent

Acupuncture treatment of pregnant women with low back and pelvic pain - an intervention study

Objective: To describe patients' experience of acupuncture treatment in low back and pelvic pain during pregnancy. Design: An intervention study carried out between September 2000 and December 2001, involving 40 pregnant women. Participants: The study population consisted of healthy pregnant women presenting with low back and pelvic pain at maternity health care centres within a defined area in so
