Comparison of passive and active methods for improving transient performance of turbocharged engine systems [PDF]

, 2006
The drive to reduce engine emissions has placed an emphasis upon turbocharging especially with the trend of engine downsizing (C. Macrae, (2006), A. Lefebvre et al. (2005)). Turbocharged vehicles exhibit a weak point of poor drivability under transient

Numerical study on temperature response of microheater and evolution characteristics of superheated zone under fast transient heating

Case Studies in Thermal Engineering
The nucleate boiling process that occurs on the surface of a microheater immersed in a liquid pool under fast transient heating conditions can be regarded as homogeneous or near-homogeneous nucleation, exhibiting a significant difference when compared to

The contrasting response of outlet glaciers to interior and ocean forcing [PDF]

The Cryosphere, 2020
The dynamics of marine-terminating outlet glaciers are of fundamental interest in glaciology and affect mass loss from ice sheets in a warming climate. In this study, we analyze the response of outlet glaciers to different sources of climate forcing.

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

FEBS 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 ...

A Low-Noise Current-Squared Delta-Sigma-Modulation Boost Converter Suitable for Low-Voltage Wireless Sensor Networks With Transient-Accelerated Techniques

IEEE Access
This paper presents a low-noise current-squared delta-sigma-modulation boost converter suitable for low-voltage wireless sensor networks with transient-accelerated techniques. There are two current-controlled loops and two voltage-controlled loops in the

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Mechanisms of Geometric Parameter Influence on Fast Transient Response Process of the Flow Path Under Inertial Forces

Applied Sciences
This study investigates the evolution of axial loads in the secondary air system following shaft failure in aeroengines. It addresses a significant gap in the existing literature regarding the effects of inertial forces within the cavity, as well as the ...

High spatio-temporal resolution pollutant measurements of on-board vehicle emissions using ultra-fast response gas analyzers [PDF]

Atmospheric Measurement Techniques, 2018
Existing ultra-fast response engine exhaust emissions analyzers have been adapted for on-board vehicle use combined with GPS data. We present, for the first time, how high spatio-temporal resolution data products allow transient features associated ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
