OBJECTIVES The goal of this study was to compare regadenoson and dipyridamole hyperemia for quantitative myocardial perfusion imaging. BACKGROUND Regadenoson is commonly used for stress perfusion imaging. However, no study in nuclear cardiology has employed a paired design to compare quantitative hyperemic flow from regadenoson to more traditional agents such as dipyridamole. Additionally, th...

Abstract We present the characterization of a readout Application-Specific Integrated Circuit (ASIC) for CMS Endcap Timing Layer (ETL) High-Luminosity LHC upgrade with charge injection. The ASIC, named ETROC and developed in 65 nm CMOS technology, reads out 16× 16 pixel matrix Low-Gain Avalanche Detector (LGAD). jitter contribution from is required to be below 40 ps achieve 50 overall time reso...

During the development of a CN Ⅵ light vehicle equipped with GDI gasoline engine, phenomenon high PN appeared. In response to operating conditions engine running in WLTC cycle, corresponding SOI sweep was performed on dyno bench. The emissions has reduced by optimizing SOI. results show that when is sufficiently advanced, oil film formed collision spray and piston causes increase significantly....
