Miniaturised sharp rejection bandpass filter with reconfigurable bandwidth for UWB applications

open access: yes, 2013
A novel, compact and highly selective microstrip bandpass filter with bandwidth reconfigurability for ultra-wideband (UWB) applications is presented. The proposed design uses stepped impedance resonator (SIR) for realization of bandpass filter (BPF) and ...

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

open access: yesAdvanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

Compact microstrip pseudo-interdigital stepped impedance bandpass filters with improved stopband performance

open access: yes, 2009
In this paper we present design of a compact microstrip pseudo-interdigital stepped impedance bandpass filter with improved stopband performance. Stepped-impedance resonators are used to maximise the ratio between higher order and fundamental resonances.

Dielectric resonators and filters for cellular base-stations [PDF]

open access: yes, 2003
The investigation into three types of dielectric resonators for use in base-station filtering applications is presented. The triple-mode cubic TE016 resonator is shown to have good performance for high Q applications.

A reduced sample rate bandpass sigma delta modulator

open access: yes, 1999
This paper introduces a bandpass sigma-delta converter which incorporates bandpass sampling, and which can therefore be clocked at frequencies well below the centre frequency of the input. The device is very efficient in terms of the hardware required. A

Unusual Thermally Induced Blueshift and Emission Amplification of Mn2+ Ions Enable Filter‐Free Luminescent Thermal Imaging

open access: yesAdvanced Science, EarlyView.
ABSTRACT The shift from point‐based thermal sensing to filter‐free thermal imaging requires luminescent thermometers that exhibit pronounced and thermally driven spectral changes within spectral regions matching the sensitivity profiles of the red, green and blue (RGB) channels of a digital camera.

Design of Quad-Channel Diplexer and Tri-band Bandpass Filter Based on Multiple-Mode Stub-Loaded Resonators [PDF]

open access: yesRadioengineering, 2019
Multiple-mode stub-loaded resonator with quad channel diplexer and tri-band bandpass filter are presented and analyzed theoretically in this paper. The multi-mode stub-loaded resonator employs the basic structure of a triple mode resonator.

In Situ Confinement of 0D Halometallates Within Deep Eutectic Solvents: From Systematic Screening to Metal‐Tunable Luminescence for Anti‐Counterfeiting Eutectogels

open access: yesAdvanced Science, EarlyView.
We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).
