Aging Is a Key Driver for Adult Acute Myeloid Leukemia
Aging and Cancer, EarlyView.Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Improvement of the air supply system for diesel locomotives
Вестник Научно-исследовательского института железнодорожного транспорта, 2023 Introduction. The diesel air supply system is designed to increase the air supply to the piston part of the engine, which increases its power. The system includes a supercharging unit (turbocharger) and an aftercooler. As their connection with the piston

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Model and control of fuel supply systems of hydrogen/oxygen fuel cell
The Journal of Engineering, 2017 Fuel supply systems have a great impact on output characteristics and lifetime of the hydrogen/oxygen fuel cell. On the basis of the fuel supply systems of the fuel cell, this study has studied the models of hydrogen supply system and oxygen supply system. Moreover, the fuzzy self‐adaptive proportional–integral–derivative (PID) controllers for hydrogen

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
