A Dual-polarized Broadband Planar Antenna and Channelizing Filter Bank for Millimeter Wavelengths
, 2013 We describe the design, fabrication, and testing of a broadband log-periodic antenna coupled to multiple cryogenic bolometers. This detector architecture, optimized here for astrophysical observations, simultaneously receives two linear polarizations ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Compact MIMO Antenna for Multiband Mobile Applications
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsThis paper presents a multiple input multiple output (MIMO) antenna for multiband operation based on meander lines with L shaped metallic strip. Meander lines is basically a monopole antenna loaded with multiple sections of short circuited transmission ...

Isolation of a transcriptionally active element of high copy number retrotransposons in sweetpotato genome [PDF]
, 2004 Many plant retrotransposons have been characterized, but only three families (Tnt1, Tto1 and Tos17) have been demonstrated to be transpositionally competent.
