Synthesis of switched-current Ladder Derived Group delay Equalizers

open access: yes, 2002
This paper describes the design of switched-current group delay equalizers. The design process is based on the pole-zero mirroring technique; with equalizer z-transfer functions generated using an optimization algorithm.

Extended Dissipativity Analysis for Uncertain Neutral-Type Semi-Markovian Jump Systems via Two Integral Inequalities

open access: yesMachines
This paper addresses the problem of extended dissipativity analysis for uncertain neutral-type semi-Markovian jump systems. Two novel parameter-dependent, free-matrix-based integral inequalities are proposed by introducing some adjustable parameters ...

A Switching-Method for nonlinear systems

open access: yesJournal of Computational and Applied Mathematics, 1996
The paper is intended to present an iterative method for the solution of nonlinear equations. This method consist in combining a direct search method and a damped approximate Newton method in order to avoid the computation of the Jacobian. The obtained hybrid method (called switching-method, due to the fact that at each iteration just one of the above ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

System-performance analysis of optimized gain-switched pulse source employed in 40-and 80-Gb/s OTDM systems [PDF]

open access: yes, 2007
The development of ultrashort optical pulse sources, exhibiting excellent temporal and spectral profiles, will play a crucial role in the performance of future optical time division multiplexed (OTDM) systems. In this paper, we demonstrate the difference

MITF maintains genome stability in nonmelanocyte lineages

open access: yesMolecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Stability Results of a Class of Hybrid Systems under Switched Continuous-Time and Discrete-Time Control

open access: yesDiscrete Dynamics in Nature and Society, 2009
This paper investigates the stability properties of a class of switched systems possessing several linear time-invariant parameterizations (or configurations) which are governed by a switching law.

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

open access: yesMolecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...
