Compact Dual-Polarized/Duplex Filtering Antenna With High Isolation
IEEE Open Journal of Antennas and Propagation, 2023 This paper introduces novel dual-polarized/duplex filtering antennas with a novel filtering feeding network. The feeding network consists of an all-resonator structure, which shares a common dual-mode resonator.

A Left/Right-Handed Dual Circularly-Polarized Antenna With Duplexing and Filtering Performance
IEEE Access, 2019 A shared-radiator dual-band dual-sense circularly-polarized (CP) microstrip antenna with duplexing and filtering functions is presented. For each band, there is a coupling network, which consists of a hairpin resonator, a straight slot, and a U-slot, and

Ship and Oil-Spill Detection Using the Degree of Polarization in Linear and Hybrid/Compact Dual-Pol SAR [PDF]
, 2012 Monitoring and detection of ships and oil spills using synthetic aperture radar (SAR) have received a considerable attention over the past few years, notably due to the wide area coverage and day and night all-weather capabilities of SAR systems.

Exceptional Extended Dual Polar Spaces
European Journal of Combinatorics, 1997 It is considered an extended dual polar space (EDPS). An EDPS \({\mathcal G}\) is called affine if there is a flag-transitive automorphism group \(G\) and a normal subgroup \(T\) in \(G\) such that \(T\) acts regularly on the set of elements of type 1 in \({\mathcal G}\). Theorem. Let \({\mathcal G}\) be an EDPS whose rank is greater than or equal to 3

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Dual-polarized all-angle cloaking of a dielectric nanowire by helical graphene ribbons
, 2019 Scattering from a dielectric nanowire coated by helical graphene strips (nanoribbons) is investigated for dual-polarized wave at oblique incidence. In the long-wavelength approximation, the helical strips are treated as a homogeneous layer with averaged ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.
