The Regulation of Trace Metal Elements in Cancer Ferroptosis

open access: yesAdvanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Photovoltaic Equalizer Based on Single-Input Multi-Output Push-Pull Converter

open access: yesXibei Gongye Daxue Xuebao, 2020
Component mismatch often happens in the module-series photovoltaic system(including centralized, string, multi-strings PV system) due to partial shadowing, which causes a large loss of power generation. Photovoltaic equalizer can process the differential

Double‐layer equalizer with multi‐winding transformer and resonance switched capacitor module for series‐connected batteries

open access: yesIET Power Electronics, 2022
A double‐layer architecture for series‐connected modules is proposed to decrease the long battery string's equalizer circuit complexity, which is based on multi‐winding transformers and resonance switched capacitors.

Non-equal-time Poisson brackets [PDF]

open access: yesarXiv, 1998
The standard definition of the Poisson brackets is generalized to the non-equal-time Poisson brackets. Their relationship to the equal-time Poisson brackets, as well as to the equal- and non-equal-time commutators, is discussed.

Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.

Digital Equalization of Ultrafast Data Using Real-time Burst Sampling [PDF]

open access: yesarXiv, 2009
We demonstrate digital equalization of 40Gbps data enabled by use of Real-time Burst Sampling (RBS) with photonic time-stretch A/D converter. Evaluation of a feed-forward equalizer and a decision feedback equalizer is also shown.

A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

open access: yesAdvanced Engineering Materials, EarlyView.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

Bandwidth Efficiency Enhancement for OFDM System Using Hybrid Equalization Techniques [PDF]

open access: yesEngineering and Technology Journal, 2009
The Cyclic prefixed OFDM systems are very robust to multipath, provided that the delay spread of the transmission channel is less than the length of the CP inserted between transmitted symbols.

QMA(2) with postselection equals to NEXP [PDF]

open access: yesarXiv, 2018
We study the power of QMA(2) with postselection and show that the power is equal to NEXP. Our method for showing this equality can be also used to prove that other classes with exponentially small completeness-soundness gap equals to the corresponding postselection versions.

Fractographic Analysis and Fatigue Behavior of Additively Manufactured Ni‐Superalloy Components with Post Processing Heat Treatment and Hot Isostatic Pressing

open access: yesAdvanced Engineering Materials, EarlyView.
A study of mechanical properties and fractography of PBF‐LB/M‐built Inconel 718, performing heat treatments and hot‐isostatic pressing, is presented. Ultimate tensile strength and fatigue behavior are evaluated, examining differences in maximum load behavior, elongation, and regimes of fatigue.
