False Data Injection Attacks on Phasor Measurements That Bypass Low-rank Decomposition

, 2017
This paper studies the vulnerability of phasor measurement units (PMUs) to false data injection (FDI) attacks. Prior work demonstrated that unobservable FDI attacks that can bypass traditional bad data detectors based on measurement residuals can be ...

Optimal PMU placement using Iterated Local Search

International Journal of Electrical Power & Energy Systems, 2010
An essential tool for power system monitoring is state estimation. Using PMUs can greatly improve the state estimation process. However, for state estimation, the PMUs should be placed appropriately in the network. The problem of optimal PMU placement for full observability is analysed in this paper.

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.

Reliably optimal PMU placement using disparity evolution-based genetic algorithm [PDF]

, 2017
Phasor Measurement Units (PMUs) are an important component in Wide Area Protection (WAP)- based operations in power systems. It is needed that a certain placement scheme of PMUs is suggested if power system scale gets larger. The optimal placement of PMU

Exercise‐induced dynamic hyperinflation in chronic obstructive pulmonary disease

Experimental Physiology, EarlyView.
Abstract Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease caused by inhalation of noxious particles, most commonly cigarette smoking. The consequent changes in airways, lung parenchyma and pulmonary vasculature lead to increased resistive, elastic and threshold loads and impaired capacity of the respiratory muscle pump. COPD

Sequential Discrete Kalman Filter for Real-Time State Estimation in Power Distribution Systems: Theory and Implementation

, 2017
This paper demonstrates the feasibility of implementing Real-Time State Estimators (RTSEs) for Active Distribution Networks (ADNs) in Field-Programmable Gate Arrays (FPGAs) by presenting an operational prototype.

The landscape of dementia research, diagnosis, treatment, and care in Latin America

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Latin America is undergoing rapid population aging alongside a rising burden of dementia. While the region holds substantial potential for dementia risk reduction, challenges remain, such as delayed diagnoses, limited access to specialized care and biomarker testing, persistent stigma, and deep‐rooted structural inequities.

Optimal PMU Placement Considering with HVDC Links and Their Voltage Stability Requirements [PDF]

AUT Journal of Electrical Engineering, 2019
In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network.

Attitude and Involvement Regarding Sexual and Reproductive Health Among University Students: A Cross‐Sectional Study in Bangladesh

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Sexual and reproductive health (SRH) is a crucial aspect of overall health and well‐being, especially among young adults. However, in many low‐ and middle‐income countries, including Bangladesh, SRH issues remain underexplored due to sociocultural taboos, stigma, and inadequate education.
