A Generic Control-Oriented Model Order Reduction Approach for High Step-Up DC/DC Converters Based on Voltage Multiplier

Energies, 2019
The modeling and control system design of high step-up DC/DC converters based on voltage multipliers (VMs) are difficult, due to the various circuit topologies and the presence of large number of capacitors in VMs.

Very Low Power Cockcroft-Walton Voltage Multiplier for RF Energy Harvesting Applications [PDF]

, 2019
A device was required that could harvest the electromagnetic energy present in ambient radio frequency (RF) signals. A part of this device must convert the AC RF signal received by the antenna into a DC signal that can be used in an embedded application.

Current/voltage hybrid multiplier

Electronics Letters, 1988
An idea is investigated that combines traditional voltagebased logic with recently presented current-mode logic into one architecture. The combined implementation constitutes a hybrid multiplier. Each logic mode contains attributes that compensate for undesirable characteristics incorporated into the alternative technology.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Effect of The Number of Array Elements from Printed Yagi Antenna Against Power Acquisition Efficiency for Implementation RF Harvesting Energy on Frequency 2.4 GHz

Jurnal Jaringan Telekomunikasi, 2022
Most low-power electronics, such as remote sensors and embedded devices, are powered by batteries. Replacement is expensive when there are hundreds of sensors in remote locations.

Construction and Performance of a Micro-Pattern Stereo Detector with Two Gas Electron Multipliers [PDF]

, 2001
The construction of a micro-pattern gas detector of dimensions 40x10 cm**2 is described. Two gas electron multiplier foils (GEM) provide the internal amplification stages. A two-layer readout structure was used, manufactured in the same technology as the

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
