This paper presents a novel design of compact contra-directional coupler with high directivity for high-power monitoring in frequency. Microstrip parallel coupled lines are widely used directional couplers; however, they show poor inherently. Their has been improved by many works. However, the suggested approaches often result other limitations, such as weak structure monitoring, or larger size...

Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

introduction left ventricular free wall rupture (lvfwr) is a frequent cause of death after acute myocardial infarction, and its repair remains a surgical challenge. conclusions a hemodynamic study was acceptable at a 12-month follow-up, and no complication was seen. case presentation tachosil® is a ready-to-use equine collagen patch which has been successfully used for hemostasis in cardiovascu...

A back-projection technique allows seismologists to analyse rupture properties once seismic signals from a dense array of networks are available. The observed waveforms then traced back in space and time the source region an earthquake under investigation. In this study, method utilised image recorded high-frequency P -seismic filtered at 0.25-1.0 Hz by Multiple Signal Classification (MUSIC) pr...

purpose rupture of pectoralis major (pm) occurs most commonly as a result of an indirect mechanism associated with extensive tension on a maximally contracted muscle. patients with pm tendon ruptures, classically present a history of sudden severe pain in arm and shoulder at the time of injury. treatment options vary from conservative to operative. in cases with total or near-total injuries, su...

We apply kinematic and dynamic modeling to the 2015 Mw8.3 Illapel, Chile, earthquake constrained by continuous high-rate GPS strong motion data. Kinematic inversion elliptical patches allows us rapidly outline ruptured area with different time windows frequency ranges. The preferred solution indicates that main large patch in north is preceded a small one south close hypocenter shift no greater...

The requirement of high data-rate in the fifth generation wireless systems (5G) calls for the ultimate utilization of the wide bandwidth in the mmWave frequency band. Researchers seeking to compensate for mmWave's high path loss and to achieve both gain and directivity have proposed that mmWave multiple-input multiple-output (MIMO) systems make use of beamforming systems. Hybrid beamforming in ...
