Following the description of in 2016 from the cloud forest of the Cofre de Perote volcano, Mexico, the doubt about the existence of another unlocalized and sympatric species of remained. After years of searching, the second endemic species of the Cofre de Perote volcano, , is presented here. It belongs to the section Umbellatae, and is described, illustrated, and compared with and , recently described from Veracruz, the second state with the highest diversity of in Mexico. The species is only known from the type locality and is classified in the Critically Endangered CR B1+B2(a,biii) category of the IUCN Red List conservation assessments.

Small lakes are common across the Boreal-Arctic zone. Due to shallowness and high shoreline-surface area ratios, they are abundant in aquatic macrophytes. Vegetated littoral zones have been suggested to count as wetlands when quantifying carbon sinks and sources, but the actual magnitude of aquatic vegetation is seldom quantified.

Twelve new species of Fletcher, 1927 (Coleoptera: Staphylinidae: Pselaphinae: Euplectitae: Metopiasini) from Ecuador are described: , , , , , , , , , , , and A key for all species of is provided. These are the first records of the genus for the country, and we report species from most major environments in the country, from seasonal coastal forests to cloud forests and the Amazonian Basin. The new species expand the scope of morphological variability in the genus, with discovery of numerous microphthalmous and wingless species, and a range of previously unreported secondary sexual characters.

Introduction: Compared to the large number of chloroplast genome resources in , only six mitogenomes (belonging to three sections) have been reported. To date, no mitogenome has been reported for section , a representative species whose chloroplast genome has been characterized, is an endangered tree endemic to the montane cloud forests of southern China.
Methods: In this study, we assembled and annotated the mitogenome of section () for the first time using the HiFi reads.

The increasing prevalence of cardiovascular diseases underscores the need for efficient and user-friendly tools to monitor heart health. Traditional Holter monitors, while effective, are often bulky and inconvenient, limiting their use in real-world scenarios. This study introduces the Smart Portable Holter, a wireless device designed for real-time cardiac monitoring, enabling early detection of heart irregularities with enhanced accuracy and user convenience.

The hydrologic cycle is increasingly disrupted due to the rising human population and the associated decline in forest trees. The rationale of this work was to address the disruption in the hydrologic cycle, which is caused by the dual adverse effects of human population growth: reducing forestry trees and diminishing clouds' formation. The proposed model assumes that the density of forestry trees decreases due to harvesting activities to fulfill the resource demands of human population.
