How Real-Time Case-Based Malaria Surveillance Helps Zanzibar Get a Step Closer to Malaria Elimination

04 Apr 2024  |  ghspjournal.org
Zanzibar has made significant strides towards malaria elimination through the development and scale-up of the Malaria Epidemic Early Detection System (MEEDS) and the malaria case notification (MCN) platform. These systems enable real-time surveillance and reporting of malaria cases, facilitating timely responses. The MCN platform, which includes an interactive SMS system, a mobile application, and a web-based analytics application, is based on free and open-source software. It has been scaled up to cover all health facilities in Zanzibar, with the Ministry of Health integrating it with the DHIS2 system to streamline data management. The Zanzibar Malaria Elimination Program (ZAMEP) has established performance standards for case notification and follow-up, aiming for high timeliness and completeness in case management.

Empowering Strategies for Lifestyle Interventions, Diet Modifications, and Environmental Practices for Uterine Fibroid Prevention; Unveiling the LIFE UP Awareness

12 Mar 2024  |  mdpi.com
Uterine fibroids disproportionately affect women of color and often lead to invasive surgeries. The LIFE UP awareness strategy emphasizes early management of uterine fibroids through lifestyle interventions, dietary modifications, and environmental practices. This approach aims to prevent fibroids, improve reproductive health, reduce invasive procedures, and save costs. The review calls for future research and policy initiatives in women's health, highlighting the importance of prevention and early intervention.

Calibration of Ring Oscillator-Based Integrated Temperature Sensors for Power Management Systems

11 Jan 2024  |  MDPI
The article presents a detailed study on the development and calibration of ring oscillator-based integrated temperature sensors for power management systems, specifically in system-on-chip (SoC) based DC-DC converters. The research identifies a quadratic relationship between oscillator output frequency and temperature, proposing several trimming-free calibration techniques. The Corrected One-Point calibration method, which requires only a single ambient temperature measurement, emerges as a practical solution, reducing the maximum error to within ±2.95°C. The Two-Point and Three-Point calibration methods also demonstrate high precision. The study concludes that accurate temperature sensor calibration can be achieved without circuit trimming, offering a viable alternative to traditional methods.

Exploring Propagating Soliton Solutions for the Fractional Kudryashov–Sinelshchikov Equation in a Mixture of Liquid–Gas Bubbles under the Consideration of Heat Transfer and Viscosity

24 Oct 2023  |  mdpi.com
The study investigates soliton solutions for the Fractional Kudryashov–Sinelshchikov Equation (FKSE) using conformable fractional derivatives and the modified Extended Direct Algebraic Method (mEDAM). The FKSE models the behavior of pressure waves in liquid–gas bubble mixtures, considering heat transmission and viscosity effects. The research yields various soliton solutions, including generalized trigonometric, hyperbolic, and rational functions with kinks, singular kinks, multi-kinks, lumps, shocks, and periodic waves. These solutions are visualized through graphs, providing insights into the complex wave behaviors in such mixtures. The findings have implications in mathematical physics and other applied sciences like optical fiber research and plasma physics.

Exact Solutions of M-Fractional Kuralay Equation via Three Analytical Schemes

04 Oct 2023  |  mdpi.com
This article presents new analytical wave solutions to the Kuralay-II equations using the truncated M-fractional derivative. Three analytical schemes, namely the exp a function, the extended sinh-Gordon equation expansion, and the generalized Kudryashov schemes, were utilized to obtain the solutions. The results are verified using Mathematica tool and illustrated with 2-D, 3-D, and contour plots. The study suggests that these methods are effective and reliable for solving other nonlinear partial differential equations and could be useful in nonlinear optics, ferromagnetic materials, and optical fibers.

Adaptive Estimation of Quasi-Empirical Proton Exchange Membrane Fuel Cell Models Based on Coot Bird Optimizer and Data Accumulation

02 Jun 2023  |  www.mdpi.com
The study presents an adaptive parameter estimation technique for developing robust proton exchange membrane fuel cell models over their lifespan, which is crucial for accurate monitoring, analysis, design, and control, thereby increasing the fuel cell's life. The research compares nine recent optimization algorithms, focusing on solution accuracy and computational burden. The coot-bird-algorithm-based technique demonstrated superior performance, outperforming competitors in accuracy and computational speed. The technique was applied to five commercial proton exchange membrane fuel cells, with statistical analysis confirming its effectiveness. The proposed adaptive modeling technique can reflect uncertainties in fuel cell performance due to degradation and changes in operating conditions.

Editorial: Linked open bibliographic data for real-time research assessment

23 Mar 2023  |  Frontiers
The article discusses the significance of open bibliographic data for real-time research assessment, highlighting the limitations of traditional research evaluation methods and the potential of linked open data to improve these practices. It emphasizes the importance of permissive licenses for bibliographic knowledge graphs and the need to address inconsistencies and biases in these databases. The article also presents a collection of research works that explore the automatic generation of real-time research assessment reports, the use of open data for transparent research evaluation, and the development of dashboards for scholarly assessment. It concludes by stressing the transformative impact of open bibliographic data on research evaluation and scholarly communication.
