The design and measured results of a compact, low cost, low conversion loss microstrip single balanced Schottky diodes mixer is proposed. This mixer is designed for Ka-band satellite transponder simulator to convert the 30 GHz radio-frequency (RF) signal down to the 20GHz intermediate-frequency (IF) signal with 9.8 GHz local oscillator (LO) frequency. This design takes full advantage of the fre...

For millimeter waves applications in the W-band 93.5-95.5 GHz, improved frequency synthesizers are highly demanded. Improved synthesizer should be tunable with high step resolution and possess phase noise performance, low spurious harmonic levels short locking time. These parameters conflicting developing a precision oscillator pure spectrum. Therefore, it's necessary to make compromisation bet...

Latent equine herpesvirus type 1 (EHV-1) infection is common in horse populations worldwide and estimated to reach a prevalence nearing 90% in some areas. The virus causes acute outbreaks of disease that are characterized by abortion and sporadic cases of myeloencephalopathy (EHM), both severe threats to equine facilities. Different strains vary in their abortigenic and neuropathogenic potentia...

Postoperative recurrence of hepatocellular carcinoma (HCC) is presented as local recurrence (LR) or extrahepatic metastasis (EHM). Recent studies indicated that EHM requires additional cellular alterations. This study aimed to examine the clinical and molecular prognostic predictors of these two events. HCC patients (289) [training cohort (n=160) and verification cohort (n=129)] receiving surgi...

– We investigate dissipative quantum transport in extended periodic systems that are subjected to electric harmonic mixing fields Ehm(t) = E1 cos(Ωt)+E2 cos(2Ωt+φ). Although such a drive possesses no net bias on average, the interplay of quantum dissipation and nonlinear response causes a finite directed current. We thus discover the paradigm of a dissipative quantum rectifier. The quantum curr...
