Design and Analysis of a Compact GSM/GPS Dual-Band Bandpass Filter Using a T-Shaped Resonator [PDF]
Journal of Electromagnetic Engineering and Science, 2022 This study presents an ultracompact dual-band bandpass filter with controllable transmission zeros based on quarter-wave dual-mode resonator for GSM (global system for mobile communications) and GPS (global positioning system) wireless applications.

Transmission Properties of the oscillating delta-function potential
, 2001 We derive an exact expression for the transmission amplitude of a particle moving through a harmonically driven delta-function potential by using the method of continued-fractions within the framework of Floquet theory.

Physical Meaning of Zeros and Transmission Zeros from Bond Graph Models [PDF]
IFAC Proceedings Volumes, 1996 Abstract The power flow within a physical system determines its dynamic behaviour, of which zeros are an important characteristic. For this, the bond graph representation is used to visualize the paths of power flow and the energy interaction between the elements.

NOVEL MICROSTRIP BANDPASS FILTERS WITH TRANSMISSION ZEROS [PDF]
Progress In Electromagnetics Research, 2007 Some design methods for band-pass filters based on half- wavelength resonators have been proposed. The main feature of these methods is that n or n + 1transmission zeros can be generated for a structure composed of n resonators. To demonstrate the usefulness of the proposed filter structures, three kinds of two-pole compact microstrip hairpin filters ...

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity
Molecular Oncology, EarlyView.Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Miniaturised microstrip dipexers for WiMAX applications [PDF]
, 2008 Miniaturised microstrip diplexer and bandpass filters using single ring resonators with good transmission and reflection characteristics on each channel for WiMAX applications have been presented. The size of the proposed diplexer is reduced.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
