We demonstrate anomalous reflectors at 140 GHz for the application of 6G communication coverage expansion. The reflectors are designed on cyclo-olefin polymer (COP) substrates on the basis of measured complex permittivity and conductivity at millimet

The least understood mechanism during heme degradation by the enzyme heme oxygenase (HO) is the third step of ring opening of verdoheme to biliverdin, a process which maintains iron homeostasis. In response to this mechanistic uncertainty, we launche

A 52-year-old man had bilateral ureteral stents placed before treatment for ureteral and renal stones, but did not return for treatment and follow-up. Three years later, he complained of hematuria and vertigo. An abdominal X-ray revealed large renal
