Study on AGC strategy involving the frequency control of HVDC power regulation

Energy Reports, 2022
The asynchronous interconnection between the Southwest China power grid (SCPG) and Central China power grid (CCPG) reduces the inertia of rotation of SCPG to 1/5, which leads to a prominent risk of frequency stability.

A Single‐Capillary Open Microfluidic Probe for Robust and Versatile Spatial Multi‐Omics Using Ambient Mass Spectrometry Imaging

Advanced Science, EarlyView.
This study reports a knot‐shaped single‐capillary open microfluidic probe (Knot‐probe) for robust and versatile spatial omics, enabling ambient mass spectrometry imaging with high spatial resolution, throughput, and structure‐resolved capability. Knot‐probe mitigates the trade‐off between analytical performance and operational robustness, providing an ...

Functional Specialization of Respiratory and Olfactory Mucus Revealed by Proteomic Profiling

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Mucus overlies the nasal mucosa in the respiratory and olfactory regions, which perform distinct physiological functions. However, proteomic differences between respiratory mucosa (RM) and olfactory cleft (OC) mucus remain unclear.

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

Automatic Generation Control and its Implementation in Real Time [PDF]

, 2014
In power systems, the control mechanism responsible for maintaining the system frequency to the nominal value and the real power interchange between balancing authority areas to the scheduled values is referred to as automatic generation control (AGC ...

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...
