International Journal of Antennas and Propagation, 2013 The proposed antenna is a circular microstrip structure excited by four feeds and suspended with artificial magnetic conductors (AMCs). The multifeed circular microstrip antennas can generate a high circularly polarized performance by using a different ...

Multi-Port Patch Antennas for Flexible Power Combining and Feeding Choice
IEEE Access, 2018 Patch antennas with multiple feeds are proposed in this paper. The antennas consist of a traditional square patch and feeding probes that are set in a line orthogonal to the polarization direction.

Multi-Feed Metasurface Antennas: Direct Numerical Design and Experimental Validations
IEEE Access, 2023 This paper provides new designs and realizations of leaky-wave (LW) metasurface (MTS) antennas fed at multiple points. The design technique is based on the direct integral-equation solution by the Method of Moments (MoM).

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma
Molecular Oncology, EarlyView.We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Dual feeding active integrated antenna
Electronics Letters, 2002 A dual feeding active integrated antenna with high isolation between the Tx and Rx ports of a single triangular patch antenna is presented. The proposed antenna suppresses the third harmonics and isolates the Tx signal at the Rx ports to a high degree. The measured results of the return loss, isolation, and radiation patterns are provided.

Molecular Oncology, EarlyView.We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

Hoop/column antenna deployment mechanism overview [PDF]
, 1985 The hoop/column antenna program is directed toward the development of a cost effective, large area, self deploying reflector antenna system. Large surface area antenna systems are required in future space missions involving improved land communications ...
