Temporal evolution of pump beam self-focusing at the High-Frequency Active Auroral Research Program [PDF]
, 2007 On 4 February 2005 the High-Frequency Active Auroral Research Program (HAARP) facility was operated at 2.85 MHz to produce artificial optical emissions in the ionosphere while passing through the second electron gyroharmonic.

A radio-frequency mosfet driver
SAIEE Africa Research Journal, 2005 High power MOSFETs have become synonymous with power electronics applications. The ability of high power MOSFETs to act as a switch makes it the ideal switching device, where maximum voltage and zero current must occur when the device is open. When closed, the MOSFET must allow maximum current to flow with zero voltage across it.

FEBS Open Bio, EarlyView.In this study, we developed a deep learning method for mitotic figure counting in H&E‐stained whole‐slide images and evaluated its prognostic impact in 13 external validation cohorts from seven different cancer types. Patients with more mitotic figures per mm2 had significantly worse patient outcome in all the studied cancer types except colorectal ...

AMB Express, 2020 Cell suspensions of Escherichia coli and Lactobacillus acidophilus were exposed to 600-ns pulsed electric fields (nsPEFs) at varying amplitudes (Low-13.5, Mid-18.5 or High-23.5 kV cm−1) and pulse numbers (0 (sham), 1, 5, 10, 100 or 1000) at a 1 hertz (Hz)

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

A W-Band 3-D Heterogeneously Integrated Radar Transmitter and Receiver
IEEE AccessFor W-band millimeter-wave radars, chip and packaging designs are often independent. The chip architecture may restrict packaging flexibility, forcing the adoption of high-loss wire bonding, and this independent design is prone to inter-chip near-field ...
