Global Harmonic Parameters for Estimation of Power Quality Indices: An Approach for PMUs

Energies, 2020
For wide-area measurement systems and smart grids, phasor measurement units (PMUs) have become key elements since they provide synchronized information related to the fundamental frequency components of voltages and currents.

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Towards Artificial Intelligence Hardware With 3D Integrated Ferroelectric Transistors

Small, EarlyView.
Modern AI workloads demand hardware that mitigates the data‐movement bottleneck of von Neumann architectures. Here, we demonstrate a 4‐tier monolithic 3D (M3D) platform vertically integrating IGZO access transistors with Hf₀.5Zr₀.5O2 ferroelectric FETs.

Observability-Enhanced PMU Placement Considering Conventional Measurements and Contingencies

Iranian Journal of Electrical and Electronic Engineering, 2014
Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be

Experimental Quantification of Hardware Requirements for FPGA-Based Reconfigurable PMUs

IEEE Access, 2019
Phasor Measurement Units (PMUs) are becoming intrinsic components of modern power systems. The synchrophasor estimation algorithms in PMUs pose stringent computational demands, which makes the application of Field Programmable Gate Arrays (FPGA) highly ...

Classification of Broadband Oscillations Using Wavelet Convolution and Multi‐Channel Attention Network

Energy Internet, EarlyView.
ABSTRACT Accurate identification of broadband oscillation types is a prerequisite for implementing appropriate control strategies. The strongly nonlinear, nonstationary and multi‐modal characteristics of broadband oscillation signals impose higher demands on identification methods. Practical applications face challenges such as coupling effects between

Implications for Newborn and Child Growth Classification Using INTERGROWTH‐21st and WHO Child Growth Standards

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective The aim of this study was to assess how the use of the WHO Child Growth Standards (WHO GS) and the INTERGROWTH‐21st Standards (IG‐21st) affect the classification and interpretation of growth trajectories. Design A secondary data analysis of an observational cohort study.

Dental Implant Rehabilitation Mitigates the Increased Mortality Risk Associated With Tooth Loss: A Population‐Based Study

Journal of Periodontal Research, EarlyView.
Fewer posterior masticatory units (PMUs) are associated with higher mortality, partly explained by diet quality. This association is attenuated by posterior prosthetic rehabilitation and is no longer evident when ≥ 5 PMUs are restored with implant‐supported prostheses. ABSTRACT Aim To (i) evaluate the association between posterior masticatory unit (PMU)

Identification of organic pigments in tattoo inks and permanent make-ups using MALDI-TOF mass spectrometry [version 1; referees: 2 approved]

F1000Research, 2017
Nowadays, about 12% of the European and 20% of the US population are tattooed. Rising concerns regarding consumer safety, led to legal restrictions on tattoo inks and permanent make-up (PMU) inks.
