Dual band FSS with fractal elements [PDF]
Electronics Letters, 1999 Experimental and computed results of a frequency selective surface (FSS) based on a certain type of fractal element are presented. The fractal element is a two iteration Sierpinski gasket dipole. Owing to the dual band behaviour of the two iteration Sierpinski gasket dipole, two stopbands are exhibited within the operating frequency band.

Miniature Multi-Band Absorptive Bandstop Filter Designs Using Bridged-T Coils
IEEE Access, 2018 In this paper, miniature absorptive bandstop filters (ABSFs) with one to three stopbands are demonstrated. First, the proposed single-band ABSF is realized by the introduction of one lossy resonator to a conventional stub bandstop filter, while the ...

A Dual-Band Approach for Backscattering Modulation
2024 IEEE International Conference on RFID Technology and Applications (RFID-TA)In typical passive UHF RFID systems, tags rely on backscattering, where they modulate a reflected signal by switching impedance states, powered solely by the reader's RF signal. In contrast, active RFID tags offer enhanced communication capabilities but require an internal power source.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Gain Enhancement of Monopole Antenna using AMC Surface
Advanced Electromagnetics, 2018 A CPW rectangular-ring antenna over an Artificial Magnetic Conductor (AMC) is presented in this work. The AMC is a designed as a dual-band structure having an array of unit cells and operates at 2.45GHz and 5.20 GHz. A CPW antenna uses this dual-band AMC

Dual Band Perfect Absorber based on Metamaterials
2022 30th Signal Processing and Communications Applications Conference (SIU), 2022 Perfect absorption can be achieved by using the extraordinary properties of metamaterials. The impedance of the metamaterial and the free space can be matched by adjusting the geometrical parameters of the resonator with the type and the thicknesses of the materials.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
