Summary: This study presents a method for timely estimation of the effective reproductive number (Re) in the COVID-19 epidemic, and evaluates it on a global scale. The results show that in most countries, the estimated Re dropped below 1 only after the introduction of major non-pharmaceutical interventions. For Europe, the implementation of these interventions was associated with reductions in the estimated Re. However, the effects of relaxing non-pharmaceutical interventions on subsequent Re estimates varied globally.

Summary: The aim of this study was to evaluate the dose response of PTB's alanine dosimeter system in UHPDR electron beams, with results showing a good precision of the system in the dose range of 0.15 Gy to 6.2 Gy per pulse. The Monte Carlo simulations were used to determine the beam quality conversion and correction factors needed for alanine dosimetry.

Summary: In this study, we propose a method to introduce reference glass dosimeters that reflect user irradiation conditions. The reference glass dosimeters are used to correct reader fluctuation by reading them simultaneously with sample glass dosimeters. Since the reference glass dosimeters can be used without annealing after irradiation for long periods, the fading effect and natural background dose accumulation need to be quantitatively considered. We establish an empirical but practical formalism for evaluating absorbed dose on the glass dosimeter, taking into account the fading effect and natural background dose accumulation.

Summary: The study shows that irradiation with 5 kGy dose of gamma rays can reduce the surface hydrophilicity of films in the 45:55 starch:PVA system, while higher doses may decrease the flexibility of the films. After irradiation, the film's swelling capacity in water decreases and solubility increases, indicating that degradation prevails over crosslinking.

Summary: Auger electron-emitters are being studied as potential radionuclides for molecular radionuclide therapy, with technetium-99m widely used for imaging but not yet fully assessed for therapeutic use. This study used MDA-MB-231.hNIS-GFP cells to model cellular radionuclide uptake, leading to observations of DNA damage and reduced clonogenicity with [Tc-99m]TcO4-, providing guidance for the safe use of technetium-99m in imaging and potential therapeutic applications.

Summary: The purpose of this study was to investigate the relationship between fluoroscopy pulse rate and absorbed radiation dose. The results showed that there was a linear correlation between fluoroscopy pulse rate and absorbed radiation dose. Using a low-dose setting significantly reduced the absorbed radiation dose compared to the standard dose. The combination of a pulse rate of 1 pulse per second and low-dose fluoroscopy reduced the absorbed dose by 97.7%.

Summary: In this study, the synthesis of a complex compound of gold with cysteine [AuCys]n for measuring absorbed dose in boron neutron capture therapy was developed. The dependence of the complex particle size on pH was established, and the release kinetics of [AuCys]n from the polymer matrix were investigated. The results showed a delayed start and specific rate of release for [AuCys]n from the composite material.

Summary: This study developed a resource-efficient machine learning framework for the discovery of radiation biomarkers using gene expression data from irradiated normal tissues. By using a KNN-based approach, novel potential radiation biomarkers were identified and showed good performance in dose and tissue separation as well as dose regression.

Summary: The study investigated occupational radiation exposure in cyclotron workers in Saudi Arabia and found that workers' doses did not exceed the dose limits set by the International Commission of Radiological Protection. It recommended that workers wear ring dosimeters for accurate measurement and use advanced absorbers to discriminate between different types of radiation.

Summary: This study shows that a single visit to the Video Interaction Project (VIP) can significantly increase responsive parenting behaviors, and a second visit further enhances the impact. Therefore, VIP should be offered widely, regardless of the ability to attend multiple visits.

Summary: This study explores the use of machine learning models to simplify and accelerate the Superpave mixture design procedure. The model predicts effective and absorbed asphalt content to achieve an automated and timesaving mix design method. The study compares different machine learning algorithms and encoding methods, and finds that the Gradient boosting model performs the best in predicting asphalt content. The proposed method is verified to be consistent with the traditional Superpave method through a case study.

Summary: Boron neutron capture therapy (BNCT) is an anticancer modality that works by accumulating B-10 in tumor cells, irradiating them with neutrons, and damaging tumor cell DNA with the release of alpha-particles and lithium nuclei. Gold nanoparticles placed inside tumor cells saturated with boron were used to accurately measure the absorbed dose, without affecting the efficiency of BNCT.

Summary: The study examined the dose-response relationships between radiation absorbed dose to the lung from uranium and external sources and circulatory system disease mortality in US uranium enrichment workers. The results indicated a modestly increased risk of ischaemic heart disease mortality with high internal uranium lung dose and significantly increased risk with external dose exceeding 150 mGy. Non-linear dose-response models showed sublinear responses, suggesting linear models may not accurately describe the association between uranium dose and circulatory system disease mortality.

Summary: Pooling individual-level data from uranium processing workers revealed increased risks of various diseases such as lung cancer, respiratory diseases, renal diseases, ischemic heart diseases, and dementia and Alzheimer's disease due to long-term exposure to uranium and external ionizing radiation. This study represents the largest investigation to date on the long-term health risks of uranium processing workers.
