Charge-transfer mediated J-aggregation in red emitting ultra-small-single-benzenic -fluorophore crystals.

Red emission in crystals has been observed with an ultra-small-single-benzenic -fluorophore () with a molecular weight (MW) of only 197 Da, bettering the literature report of fluorophores with the lowest MW = 252 Da. Supramolecular extensive hydrogen-bonding and J-aggregate type centrosymmetric discrete-dimers or a 1D chain of s led to red emission ( = 610-636 nm) in crystals. Unlike in the solution phase showing one absorption band, in thin films and in crystals the transition from the S state to both the S state and S state becomes feasible.

The epidemiology of laboratory-confirmed Hepatitis B Virus infection in the general population of South Africa, 2016-2018.

Introduction: despite the introduction of the Hepatitis B Virus (HBV) vaccine in South Africa in 1995, HBV remains endemic. South Africa's HBV vaccine coverage for the third dose was 71% in 2015. Information on the HBV prevalence in South Africa in recent years is limited, therefore, we estimated HBV prevalence and described annual trends.

Detecting and forecasting cryptojacking attack trends in Internet of Things and wireless sensor networks devices.

This research addresses the critical issue of cryptojacking attacks, a significant cybersecurity threat where malicious actors covertly exploit computational resources for unauthorized cryptocurrency mining, particularly in wireless sensor networks (WSN) and Internet of Things (IoT) devices. The article proposes an innovative approach that integrates time series analysis with graph neural networks (GNNs) to forecast/detect cryptojacking attack trends within these vulnerable ecosystems. Utilizing the "Cryptojacking Attack Timeseries Dataset," the proposed method emphasizes early detection and predictive insights to anticipate emerging attack patterns.
