Multiple Order Dual-Band Active Ring Filters with Composite Right/Left Handed Cells [PDF]
, 2010 In this paper, a novel dual-band active filter topology is presented. The non-linear phase response of a composite right/left-handed cell is used to achieve the desired dual-band performance.

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.

Crumpled textile antennas [PDF]
, 2009 The performance of a dual-band textile antenna under two-dimensional crumpling conditions is described. Both input impedance and radiation patterns are investigated based on numerical and experimental methods at 2.45 and 5.8 GHz.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...
