Studies of Single Electroweak Bosons at the Tevatron

Tests of the Standard Model with Electroweak Physics have been performed over many decades. In these proceedings, we present several analyses from the Tevatron involving single $W$ or $Z$ bosons.Comment: XIX International Workshop on Deep-Inelastic Scattering and Related Subjects (DIS 2011

Testing the Standard Model with WGamma and ZGamma at the Tevatron

Results on analyses involving WGamma and ZGamma production from the CDF and D0 experiments at the Fermilab Tevatron Collider at Sqrt(s) = 1.96 TeV are presented here. Using 1-2 fb^-1 of data, cross sections, anomalous coupling limits, and the WGamma Radiation Amplitude Zero are reviewed.Comment: Parallel talk at ICHEP08, Philadelphia, USA, July 200

Permanent His-bundle Pacing in Pediatrics and Congenital Heart Disease

Permanent His-bundle pacing has been gaining popularity in the adult population requiring cardiac resynchronization therapy. Initial procedural challenges are being overcome, and this method of pacing has been shown to improve left ventricular function and heart failure symptoms secondary to ventricular dyssynchrony. Though the etiologies of ventricular dyssynchrony may differ in children and those with congenital heart disease than in adults with structurally normal hearts, His-bundle pacing may also be a preferred option in these groups to restore more physiologic electric conduction and improve ventricular function. We present a review of the current literature and suggested directions involving deploying permanent His-bundle pacing in the pediatric and congenital heart disease population

This study investigated the relationship between presence of pre-hospital enhanced care teams (ECT) (Critical Care Paramedics (CCPS) or Helicopter Emergency Medical Service (HEMS)), on the scene time and triage compliance, of penetrating trauma patients in a UK ambulance service. The primary outcome was whether scene time reduces when an ECT is present. A secondary outcome was whether the presence of an ECT improved compliance with the trust's Major Trauma Decision Tree (MTDT). Methods: All suspected penetrating trauma incidents involving a patient's torso were identified from the Trust's computer-aided dispatch (CAD) system between 31st March 2017 and 1st April 2018. Only patients who sustained central penetrating trauma were included. Any incidents involving firearms were excluded due to the prolonged times that can be involved when waiting for specialist police units. Data relevant to scene time for each eligible incident were retrieved, along with the presence or absence of an ECT. The results were analysed to identify trends in the scene times and compliance with the MTDT. Results: One hundred seventy-one patients met the inclusion criteria, with 165 having complete data. The presence of an ECT improved the median on-scene time in central stabbing by 38% (29m50s vs. 19m0s, p = 0.03). The compliance with the trust's MTDT increased dramatically when an ECT is present (81% vs. 37%, odds ratio 7.59, 95% CI, 3.70-15.37, p < 0.0001). Conclusions: The presence of an ECT at a central stabbing incident significantly improved the scene time and triage compliance with a MTDT. Ambulance services should consider routine activation of ECTs to such incidents, with subsequent service evaluation to monitor patient outcomes. Ambulance services should continue to strive to reduce scene times in the context of central penetrating trauma.Peer reviewe

A Search for Squarks and Gluinos using the Jets and Missing Energy Signature at D0

http://www.idw-online.de/pages/de/news400327 Wissenschaftsministerin Svenja Schulze hat die heutige Entscheidung der DFG, gegen vier Wissenschaftler eine schriftliche Rüge wegen Fehlverhaltens auszusprechen, begrüßt. „Ich finde es richtig, dass die Deutsche Forschungsgemeinschaft hier klare Kante zeigt. Aber wir müssen zugleich auch etwas tun, damit es zukünftig möglichst wenig schwarze Schafe in der Forschung gibt – Open Access in der Wissenschaft kann dabei eine Antwort sein“, sagte die Min..

Head Motion Controls for 3D Head Mounted Display Games

The established methods for 3D interaction with virtual environments in games are not ideally suited for use with consumer level head mounted displays. Research towards more suitable methods for 3D interaction often focuses on the use of highly specialized input devices that are not easily available to consumer audiences. As an alternative, this research examines and explores control schemes that rely primarily on the motion of a user’s head for interaction in virtual environments, requiring no input devices beyond a head mounted display itself. Control schemes for head motion in existing games and technology demonstrations are reviewed. Several head motion control schemes for travel in virtual environments are prototyped and refined through iterative user evaluation. This research shows how head motion controls can be designed to create 3D interfaces with the objectives of comfort and learnability.M.S., Digital Media -- Drexel University, 201

Eukarion-134 Attenuates Endoplasmic Reticulum Stress-Induced Mitochondrial Dysfunction in Human Skeletal Muscle Cells

Maladaptive endoplasmic reticulum (ER) stress is associated with modified reactive oxygen species (ROS) generation and mitochondrial abnormalities; and is postulated as a potential mechanism involved in muscle weakness in myositis, an acquired autoimmune neuromuscular disease. This study investigates the impact of ROS generation in an in vitro model of ER stress in skeletal muscle, using the ER stress inducer tunicamycin (24 h) in the presence or absence of a superoxide dismutase/catalase mimetic Eukarion (EUK)-134. Tunicamycin induced maladaptive ER stress, which was mitigated by EUK-134 at the transcriptional level. ER stress promoted mitochondrial dysfunction, described by substantial loss of mitochondrial membrane potential, as well as a reduction in respiratory control ratio, reserve capacity, phosphorylating respiration, and coupling efficiency, which was ameliorated by EUK-134. Tunicamycin induced ROS-mediated biogenesis and fusion of mitochondria, which, however, had high propensity of fragmentation, accompanied by upregulated mRNA levels of fission-related markers. Increased cellular ROS generation was observed under ER stress that was prevented by EUK-134, even though no changes in mitochondrial superoxide were noticeable. These findings suggest that targeting ROS generation using EUK-134 can amend aspects of ER stress-induced changes in mitochondrial dynamics and function, and therefore, in instances of chronic ER stress, such as in myositis, quenching ROS generation may be a promising therapy for muscle weakness and dysfunction
