Design of Boost-Type Power Factor Correction With Stepped Air-Gap Ferrite Inductor for Peak-Power-Load Condition

open access: yesIEEE Access, 2022
This paper presents the designed method and the implementation of stepped air-gap ferrite inductor applied in power factor correction (PFC). Conventionally, the input inductor of the PFC has a designed consideration on the maximum output power; thus ...

Increasing the power efficiency of an IEEE802.11a power amplifier [PDF]

open access: yes, 2005
OFDM modulation is extensively used in many applications. However, it also exhibits high peak-to-average power ratios (PAPR) requiring the associated transmit amplifier to have a very large linear region.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Enhancing delay fault coverage through low power segmented scan

open access: yes, 2006
Reducing power dissipation during test has been an active area of academic and industrial research for the last few years and numerous low power DFT techniques and test generation procedures have been proposed. Segmented scan [17-20] has been shown to be

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Support Size of ε-Capacity-Achieving Inputs for the Amplitude-Constrained AWGN Channel

open access: yesEntropy
We study the discrete-time amplitude-constrained additive white Gaussian noise (AWGN) channel from the perspective of near-optimal input distributions in the high-SNR, or equivalently large-amplitude, regime. While it is known that the capacity-achieving
