Soil carbon saturation : concept, evidence and evaluation
, 2007 Current estimates of soil C storage potential are based on models or factors that assume linearity between C input levels and C stocks at steady-state, implying that SOC stocks could increase without limit as C input levels increase.

Arthritis Care &Research, EarlyView.Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

Current Transformer Saturation Detection Using Gaussian Mixture Models
, 2013 This paper presents a novel current transformer (CT) saturation detection approach based on Gaussian Mixture Models (GMMs). High accuracy is the advantage of this method. GMMs are trained with secondary current of CT.

Correction of saturated current from measurement current transformer
IET Electric Power Applications, 2013 The suggested study presents an easy and effective way to compensate for the distorted secondary current of measurement‐type current transformers (CTs). The suggested compensating algorithm is based on estimating the magnetising current from a Fröhlich hysteresis approach.

Fault Current Calculation for Inverter-interfaced Power Sources Considering Saturation Element
, 2021 The fault current of converter-interfaced renewable energy sources (CIRESs) is mainly determined by the control system of the inverter, so the traditional calculation method of short-circuit current based on voltage-flux is no longer applicable.

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
