Assessing the Feasibility of Using a Multiplex Serological Assay to Conduct Serosurveillance for Malaria Exposure in Deployed Military Personnel.

Reproducibly assessing malaria exposure is critical for force health protection for military service members deployed to malaria-endemic regions as well as for civilians making public health decisions and evaluating malaria eradication efforts. However, malaria disease surveillance is challenged by under-reporting, natural immunity, and chemoprophylaxis, which can mask malaria exposure and lead to an underestimation of malaria prevalence. In this study, we determined the feasibility of using a serosurveillance-based approach to measure Anopheles vector exposure, Plasmodium sporozoite exposure, and blood-stage parasitemia using a multiplex serological panel.

Segregation of Factors Leading to Temperature-Dependent Ion Transport in Mixed Cationic Systems in Cation Exchange Membranes.

This study delves into the interplay of temperature, composition, tortuosity, and electrostatic interactions on ion diffusion within cation exchange membranes. It explores the temperature dependence (16-60 °C) of the self-diffusion coefficients (SDCs) of Ba and Eu ions within the Nafion 117 cation exchange membrane, particularly in the presence of Na ions. Radiotracer techniques and electrochemical impedance spectroscopy were employed to investigate these SDCs.

Blockchain Based Secure Federated Learning With Local Differential Privacy and Incentivization.

Interest in supporting Federated Learning (FL) using blockchains has grown significantly in recent years. However, restricting access to the trained models only to actively participating nodes remains a challenge even today. To address this concern, we propose a methodology that incentivizes model parameter sharing in an FL setup under Local Differential Privacy (LDP).

Synergistic Chloroform-Methanol Binary Solvent Mixture Is Inherently Spatially and Dynamically Heterogeneous.

Nonideality in a binary solvent mixture is manifested through anomalies in various physical properties like viscosity, dielectric constant, polarity, freezing point, boiling point, and so forth. Sometimes, such anomalies become much more prominent, leading to a synergistic behavior, where the physical property of the mixture is way different from its bulk counterparts. Various alcohols/chlorinated methane binary solvent mixtures show such a synergistic behavior.

Progress Toward Poliomyelitis Eradication - Afghanistan, January 2023-September 2024.

Since the Global Polio Eradication Initiative began in 1988, wild poliovirus (WPV) types 2 and 3 have been eradicated, and annual polio case numbers have decreased by >99.9%. WPV type 1 (WPV1) transmission remains endemic in Afghanistan and Pakistan, two countries that share a 1,600-mile (2,600-km) border.
