Purpose This paper investigates the relationship between domestic gold prices and inflation in Vietnam based on monthly series of price index consumer over period December 2001–July 2020. Design/methodology/approach The co-integration is examined within autoregressive distributed lag-error correction (ARDL bounds testing) framework. also applies vector error model (VECM) impulse response functi...

Shock waves are one of the primary damage parameters an ammunition explosion. Therefore, accurately obtaining shock wave pressure distribution law after explosion is greatly significant for power evaluation and guidance selection in operations course. This study established mapping function between surface reflected free-field pressures, considering altitude effect on pressure. Finite element n...

Particle Image Velocimetry (PIV) has become an important tool in modern flowfield diagnostics, in particular for subsonic flows. PIV systems have also been used to measure supersonic flows in supersonic wind tunnels, but only recently it has been shown that PIV can also be a valuable tool for high-speed supersonic flows in a shock tunnel (Haertig et al., 2001). At the ISL shock tunnel a PIV sys...

BACKGROUND An increased defibrillation threshold (DFT) may limit the efficacy of an implantable cardioverter-defibrillator (ICD) in termination of life-threatening ventricular arrhythmias. A search for methods of decreasing DFT has been ongoing since the introduction of ICD into clinical practice. AIM To assess the effects of various shock polarities on DFT. METHODS The study group consiste...

in this paper we investigate the effect of oil price shocks on stock market index in iran, by using of a structural var (svar) approach. we used four variables in the model namely kilian index, global oil supply, real oil price and real stock market index. the data are monthly and spanning the period 1997m10-2014m12. we identify the effect of four different shocks on stock market including oil ...

BACKGROUND A recent study has shown that the implantable atrial defibrillator can restore sinus rhythm in patients with recurrent atrial fibrillation when therapy was delivered under physician observation. The objective of this study was to evaluate the safety and efficacy of ambulatory use of the implantable atrial defibrillator. METHODS AND RESULTS An atrial defibrillator was implanted in 1...
