Improving efficiency has long been a focal challenge in sampling literature. However, simultaneously enhancing estimator efficacy and optimizing survey costs is a practical necessity across various fields such as medicine, agriculture, and transportation. In this study, we present a comprehensive family of generalized exponential estimators specifically designed for estimating population means within stratified sampling frameworks.

The study aimed to observe the effects of intervention in three sub-types of achalasia and compare the intervention outcomes among the three sub-types.
Methods: Forty-one patients underwent Eckardt scoring for severity of achalasia, followed by high-resolution manometry (HRM).
This study explores the thermal conductivity and viscosity of water-based nanofluids containing silicon dioxide, graphene oxide, titanium dioxide, and their hybrids across various concentrations (0 to 1 vol%) and temperatures (30 to 60 °C). The nanofluids, characterized using multiple methods, exhibited increased viscosity and thermal conductivity compared to water, with hybrid nanofluids showing superior performance. Graphene oxide nanofluids displayed the highest thermal conductivity and viscosity ratios, with increases of 52% and 177% at 60 °C and 30 °C, respectively, for a concentration of 1 vol% compared to base fluid.

Despite the numerous advancements in therapeutic options, no approved vaccine is currently available for this particular bacterium. Consequently, this study focused on creating a rational vaccine design using bioinformatics tools.

Although the pathological events leading to the development of CFRD are complex and not completely understood, dietary factors may play a role. For example, habitual intake of dietary added sugar (i.
