[1] We report a new category of dayside auroral transients using auroral image data from the Polar spacecraft Ultraviolet Imager. The transients are characterized by a sudden brightening of the auroral patch in the midday subauroral zone, and thus are named midday sub-auroral patches (MSPs). MSPs were found to occur concurrently with storm sudden commencements in response to the compression of ...

International portfolio flows converge in the medium run to a country-specific, supply-side estimate of their natural level. Our level capital flows, KF*, has impressive out-of-sample empirical features, greatly improves our ability model notoriously volatile and performs well against in-sample filtering techniques. Further, gap between actual inflows KF* helps predict sudden stop episodes, equ...

Abstract We address the shocks from acoustic pulses and wave trains in general one-dimensional flows, with an emphasis on application to super-Eddington outbursts massive stars. Using approximate adiabatic invariants, we generalize classical equal-area technique its integral differential forms. predict shock evolution for case of initially sinusoidal but finite train, separate solutions interna...

Abstract A new reliability model for dependent competing failure processes is proposed. The uses the generalized Polya process (GPP) to arrival of shocks and considers degradation rate change. Most systems fail due performance external environment shocks. On one hand, soft occurs when total amount degradation, including continuous sudden degenerate increment, exceeds threshold level. other hard...

We provide evidence on the existence of short-run trade diversion effects towards third countries as a consequence tariff shocks. exploit sudden policy changes in context dispute between United States and China 2018. Based data set covering monthly product-level information US imports from 30 for period 2016 until May 2019, we employ difference-in-differences estimation framework. Doing so, can...

BACKGROUND Celivarone is a new antiarrhythmic agent developed for the treatment of ventricular arrhythmias. This study investigated the efficacy and safety of celivarone in preventing implantable cardioverter-defibrillator (ICD) interventions or death. METHODS AND RESULTS Celivarone (50, 100, or 300 mg/d) was assessed compared with placebo in this randomized, double-blind, placebo-controlled,...

Sudden cardiac arrest is one of the leading causes of death in the ndustrialized world, with approximately 50,000 events occurring very year in Japan [1], where pre-hospital care for the out-ofospital cardiac arrest patients has been progressing. Automated xternal defibrillator (AED) installation has spread rapidly around he world and AED deployment in Japan exceeds 400,000 locations. he SOS-KA...

This patient case underscores the clinical value of S-ICD as an alternative solution for younger patients, who need multiple years of ICD therapy, for sudden cardiac death prophylaxis. Introduction Brugada syndrome (BrS) is an inherited disease associated with an increased risk of developing malignant ventricular arrhythmias. These can not only cause syncope but also lead to sudden cardiac deat...

BACKGROUND Implantable cardioverter-defibrillator indications in Brugada syndrome remain controversial, especially in asymptomatic patients. Previous outcome data are limited by relatively small numbers of patients or short follow-up durations. We report the outcome of patients with Brugada syndrome implanted with an implantable cardioverter-defibrillator in a large multicenter registry. METH...

The clinical value of the implantable cardioverter-defibrillator (ICD) in reducing sudden cardiac death has been proved in selected patients with ischaemic or non-ischaemic cardiomyopathy. Since the introduction of the ICD in the 1980s, the technology has evolved from an epicardial to a transvenous approach. Recently, the subcutaneous cardioverter-defibrillator (S-ICD) has been added to the arm...
