Data on the weights and linear dimensions of the cerebella from the corpses of 80 women and 140 men aged 20-90 years were studied, using standard methods for statistical data analysis. A relationship was found between differences in the weight and the linear dimensions of the cerebellum and differences in skull size. Cerebellar weight and transverse dimensions were greater in males than in females. There were decreases in the weight and linear dimensions of the cerebellum after age 60 years.

Holey nanographene, an allotrope of carbon arranged in two dimensions, has gained remarkable attention as a nanomaterial with several potential uses in numerous industries, such as electronics, energy storage, healthcare, and environmental cleanup, because of its high carrier mobility, flexibility, transparency, high surface area, conductivity, and chemical stability. The fundamental holey nanographene is assembled in a linear form to create the holey nanographene chain (HNC) that is being discussed. To fully utilize it in various applications, it is essential to comprehend the basic ideas guiding its behavior at the nanoscale; for that, we find various topological indices for this holey nanographene chain using the cut method.

Accurately predicting the remaining useful life (RUL) is crucial for ensuring the safety and reliability of aircraft engine operation. However, aircraft engines operate in harsh conditions, with the characteristics of high speed, high temperature, and high load, resulting in high-dimensional and noisy data. This makes feature extraction inadequate, leading to low accuracy in the prediction of the RUL of aircraft engines.

The development of low-temperature piezoresistive materials provides compatibility with standard silicon-based MEMS fabrication processes. Additionally, it enables the use of such material in flexible substrates, thereby expanding the potential for various device applications. This work demonstrates, for the first time, the fabrication of a 200 nm polycrystalline silicon thin film through a metal-induced crystallization process mediated by an AlSiCu alloy at temperatures as low as 450 °C on top of silicon and polyimide (PI) substrates.

A valuable outcome measure to monitor amyotrophic lateral sclerosis (ALS) disease progression is crucial in clinical trials. Rasch-Built Overall Amyotrophic Lateral Sclerosis Disability Scale (ROADS) is a novel questionnaire assessing ALS disability. Currently, there are no studies on the relationship between ROADS and ALS survival.

Background: Concerning maternity service, the mother's quality assessment is central because emotional, cultural, and respectful support is vital during labour and the delivery process. Studies concerning the perceived quality of maternity services from the perspective of mothers have rarely been carried out in Iranian hospital settings. Therefore, this study aimed to measure the gap between the expectations of patients with maternity services and their perceptions of the service and identify associated factors at a maternity hospital in northwest Iran using service quality (SERVQUAL) and health quality (HEALTHQUAL) questionnaires.
