Ladder-simulation elliptic bandpass active-RC filter structure employing identical resistors

IET Circuits, Devices & Systems, 2009
A novel structure of the ladder-based elliptic bandpass active-RC filter is presented. Unlike the previously reported elliptic bandpass active-RC filter, the proposed filter contains resistors with identical value and is therefore more suitable for integrated-circuit realisation. Also, according to the simulation results, the proposed elliptic bandpass

Role of S1P‐ and Rho‐kinase signalling in age‐related myogenic tone deficiency in murine resistance arteries

Experimental Physiology, Volume 111, Issue 3, Page 1524-1542, 1 March 2026.
Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...

Alpha‐Actinin‐3 Deficiency Links Genetic Susceptibility to Renal Fibrosis: Evidence From Hemodialysis Patients and Murine Models

The FASEB Journal, Volume 40, Issue 4, 28 February 2026.
This study links the ACTN3 R577X polymorphism to chronic kidney disease (CKD), specifically in patients undergoing hemodialysis (HD). In parallel, increased Actn3 expression in murine models of kidney injury supports a functional role for ACTN3 in renal pathophysiology.

Non-Hermitian description of the dynamics of inter-chain pair tunnelling

, 2017
We study inter-chain pair tunnelling dynamics based on an exact two-particle solution for a two-leg ladder. We show that the Hermitian Hamiltonian shares a common two-particle eigenstate with a corresponding non-Hermitian Hubbard Hamiltonian in which the

Hidden Charge‐Order in the Mixed‐Valent K0.75Li2Cr6O12 High‐Pressure Oxide

Advanced Science, Volume 13, Issue 11, 23 February 2026.
K0.75Li2Cr6O12 is one of the few mixed valent chromium oxides. It shows a single angle spiral magnetic structure with a k = [1/3 1/3 ¼] propagation vector. Density functional theory reveals a hidden charge order that is necessary to stabilize the antiferromagnetic (AFM) ground state.

Realisation of transmission zeros with two RC parallel ladders

Electronics Letters, 1967
The polynomial decompositions due to Calahan and Horowitz can be effectively used for the synthesis of passive RC parallel ladders to realise any zeros of transmission including those on the positive real axis. Only two ladders are sufficient. One of the ladders will be connected via a voltage amplifier having a gain of ±1.

The Transformation of the Superconducting Gap to an Insulating Pseudogap at a Critical Hole Density in the Cuprates

, 2017
We apply the recent wavepacket formalism developed by Ossadnik to describe the origin of the short range ordered pseudogap state as the hole doping is lowered through a critical density in cuprates.

QCD Factorized Drell-Yan Cross Section at Large Transverse Momentum

, 2001
We derive a new factorization formula in perturbative quantum chromodynamics for the Drell-Yan massive lepton-pair cross section as a function of the transverse momentum $Q_T$ of the pair.

Quantum Monte Carlo Study of Weakly Coupled Spin Ladders

, 1999
We report a quantum Monte Carlo study of the thermodynamic properties of arrays of spin ladders with various widths ($n$), coupled via a weak inter-ladder exchange coupling $\alpha J$, where $J$ is the intra-ladder coupling both along and between the ...
