A capacitor-less low drop-out voltage regulator with fast transient response [PDF]

open access: yes, 2006
Power management has had an ever increasing role in the present electronic industry. Battery powered and handheld applications require power management techniques to extend the life of the battery and consequently the operation life of the device.

Analysis and Control of Electrolytic Capacitor-Less LED Driver Based on Harmonic Injection Technique

open access: yesEnergies, 2018
AC-DC LED drivers may have a lifespan shorter than the lifespan of LED chips if electrolytic capacitors are used in their construction. Using film capacitors solves this problem but, as their capacitance is considerably lower, the low-frequency ripple ...

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Soft-Switched Hybrid-Modulation for an Isolated DC-Link-Capacitor-Less Pulsating-DC-Link Inverter

open access: yes, 2015
The main goal of this dissertation is to increase the performance of the capacitor-less high-frequency pulsating dc-link (HFPDCL) inverters suitable for renewable energy sources. The HFPDCL inverters are compact, small foot-printed, modular, and reliable

A capacitor mismatch calibration scheme for SAR ADC based on genetic algorithm

open access: yesElectronics Letters, 2023
Capacitor mismatch problem due to process variation causes weight error, which deteriorates the linearity of SAR ADC. In this paper, a novel calibration scheme based on genetic algorithm(GA) combined with a radix‐less‐than‐2 SAR ADC is proposed to ...

Multi-Vector Model Predictive Control for Three-Phase Four-Switch Rectifier with Capacitor Voltage Balancing

open access: yesZhongguo dianli, 2019
Three-phase four-switch rectifier has the problem of unbalanced capacitor voltage because one phase of its AC side is directly connected between two capacitor neutral points on the DC side.

Super-capacitor/lead acid battery hybrid energy storage suitable for remote area power supply (raps) systems. [PDF]

open access: yes, 2010
This paper presents the results of simulations based on real load data collected from a RAPS system in the south west of Western Australia. The load data was collected at a rate of one sample per second to capture the transient changes.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
