Article Abstract
In this study, we analyzed the spread and decay durations of the COVID-19 pandemic in several cities of China, England, Germany, and Japan, where the first wave has undergone decay. Differences in medical and health insurance systems, as well as in regional policies incommoded the comparison of the spread and decay in different cities and countries. The spread and decay durations in the cities of the four studied countries were reordered and calculated based on an asymmetric bell-shaped model. We acquired the values of the ambient temperature, absolute humidity, and population density to perform multivariable analysis. We found a significant correlation ( < 0.05) of the spread and decay durations with population density in the four analyzed countries. Specifically, spread duration showed a high correlation with population density and absolute humidity ( < 0.05), whereas decay duration demonstrated the highest correlation with population density, absolute humidity, and maximum temperature ( < 0.05). The effect of population density was almost nonexistent in China because of the implemented strict lockdown. Our findings will be useful in policy setting and governmental actions in the next pandemic, as well as in the next waves of COVID-19.

Deepfakes pose critical threats to digital media integrity and societal trust. This paper presents a hybrid deepfake detection framework combining Convolutional Neural Networks (CNNs) and Generative Adversarial Networks (GANs) to address challenges in scalability, generalizability, and adversarial robustness. The framework integrates adversarial training, a temporal decay analysis model, and multimodal detection across audio, video, and text domains.

Maize (Zea mays L.) is one of the world's most widely cultivated and economically important cereal crop, serving as a staple food and feed source in over 170 countries. However, its global productivity is threatened by late wilt disease (LWD), a disease caused by Magnaporthiopsis maydis, that spreads through soil and seeds and can cause severe yield losses.

Research Question: How does a compound heterozygous DMC1 variant, a meiosis-specific recombinase, affect homologous search and chain invasion during spermatocyte meiosis in a patient with non-obstructive azoospermia (NOA)?
Design: A patient with a compound heterozygous DMC1 variant associated with NOA was identified. Reverse transcription polymerase chain reaction and western blot were used to study the effect of this variant. Standard histological analysis and immunofluorescence staining investigated the patient's spermatogenic arrest.

Sensory prostheses use arrays of electrodes to stimulate neural tissue and restore a sense of vision or hearing. At perceptible levels of stimulation, the current from each electrode spreads and causes overlapping regions of neural activation. This lack of specificity results in perceptual deficits.

High-precision micromanipulation techniques, including optical tweezers and hydrodynamic trapping, have garnered wide-spread interest. Recent advances in optofluidic multiplexed assembly and microrobotics demonstrate significant progress, particularly by iteratively applying laser-induced, localized flow fields to manipulate microparticles in viscous solutions. However, these approaches still face challenges such as undesired hydrodynamic coupling and instabilities when multiple particles are brought into close proximity.
