Static area coverage of the heterogeneous autonomous underwater vehicle (AUV) group is widely used in many fields. With the use of the centroidal Voronoi tessellation (CVT) algorithm, the coverage problem can be resolved. However, the CVT method, which is optimized with the location evaluation function, cannot consider the heterogeneity of AUVs when the group performs the static area coverage task and will cause a waste of resources. In this paper, considering different AUVs' task requirements and detection capabilities comprehensively, we propose a coverage control optimization algorithm based on a biological competition mechanism (BCM). By using BCM, the task load of each AUV can be distributed consistently. In addition, we provide strict proof of the consistency of the algorithm based on the Lyapunov method. Simulation results demonstrate that with the proposed algorithm, the location distribution of the heterogeneous AUV group for area coverage is close to the balanced value, and the performance is better than the CVT algorithm for static area coverage.

Background: The COVID-19 pandemic in Ethiopia posed additional challenges to an already strained mental health service. Eka Kotebe Hospital, the second-largest mental health facility with a capacity of 175 beds, was transformed into a dedicated COVID-19 treatment center, leaving mental health service users, especially vulnerable elderly patients with cognitive impairments, without adequate support. I had the challenge to implement alternatives to provide mental health services coverage to underserved elderly population.

Objective: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province.

Methods: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals.

Background: Expanding access to equitable health insurance is an important lever towards the overall strategy for achieving universal health coverage. In Nigeria, health insurance coverage is low with a renewed government action on increasing access to and coverage of high-quality healthcare services to citizens, particularly for the vulnerable and poor population. Therefore, our study co-creates the priorities for expanding health insurance in Nigeria, focusing on key policy reforms, public advocacy, and innovative financing strategies to ensure broader and more equitable coverage for the population.

Association between type of health insurance and dental visits among Ecuadorian older population: evidence from a cross-sectional study.

BMC Public Health

January 2025

Facultad de Ciencias de la Salud Eugenio Espejo, Universidad UTE, Centro de Investigación en Salud Pública y Epidemiología Clínica (CISPEC), Quito, Ecuador.

Background: Dental services are often overlooked within healthcare systems, despite their critical role in overall health. Socioeconomic barriers and disparities in insurance coverage frequently limit access to oral care, particularly among vulnerable populations like older adults.

Objective: To examine the impact of different health insurance types on the frequency of dental consultations among Ecuadorian senior citizens, aiming to highlight gaps in access to care.

Streptofilum capillatum was recently described and immediately caught scientific attention, because it forms a phylogenetically deep branch in the streptophytes and is characterised by a unique cell coverage composed of piliform scales. Its phylogenetic position and taxonomic rank are still controversial discussed. In the present study, we isolated further strains of Streptofilum from biocrusts in sand dunes and Arctic tundra soil.
