Dual-Band Quasi-Coherent Radiative Thermal Source

, 2018
Thermal radiation from an unpatterned object is similar to that of a gray body. The thermal emission is insensitive to polarization, shows only Lambertian angular dependence, and is well modeled as the product of the blackbody distribution and a scalar ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

DUAL BAND FILTER DESIGN USING REAL FREQUENCY TECHNIQUE AND FREQUENCY TRANSFORMATION

Electrica, 2017
In this work, we present a frequency transformation based dual-band filter design approach using scatteringbased real frequency technique. In the design process, conventional low-pass to band-pass frequency transformation isintegrated with the simplified

Composite metamaterials with dual-band magnetic resonances in the terahertz frequency regime

, 2009
Composite metamaterials(CMMs) combining a subwavelength metallic hole array (i.e. one-layer fishnet structure) and an array of split-ring resonators(SRRs) on the same board are fabricated with gold films on silicon wafer. Transmission measurements of the

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Behavioral Modeling and Predistortion of Dual-Band Power Amplifiers

IEEE Access
Dual-band power amplifiers (PAs) are essential components in modern wireless communication systems. Compared to single band PAs, dual-band PAs enable efficient utilization of spectrum resources with lower capital and operational expenses.

A 24/77 GHz Dual-Band Receiver for Automotive Radar Applications

IEEE Access, 2019
A fully-integrated 24/77 GHz dual-band receiver is presented for automotive radar applications. The proposed receiver consists of a dual-band LNA, a dual-band sub-sampling PLL, and a wideband mixer, operating at 24 and 77 GHz alternatively.

Dual-band switched beam array fed by dual-band Butler matrix

Electronics Letters, 2011
A two layer dual-band switched beam system operating at two separate frequency bands is proposed. This system consists of a dual-band 4×4 Butler matrix at the bottom layer and a dual-band microstrip antenna array at the top layer. The antenna array is fed by a Butler matrix to produce four beams that can be tilted in different four directions.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
