The results of studies of the peculiarities of formation of phytocenoses in environments contact sites of the western and eastern coasts of the Lake Baikal has been showed in this paper. On the base of geobotanic profiling combined with soil one, the structure and dynamics of phytocenoses forming under the conditions of mutual development of light-coniferous taiga forest and of extra zonal steppes. Edaphic conditions and placement of phytocenoses are main trigger factors determining the ways of plant cover development in this part of Lake Baikal basin. We discuss the characteristics properties inherent in the linkage of the dynamics and spatial variability of the vegetation with the change of climate in the Baikal region. The regional conditions of the physiogeographic environment had given rise to structurally highly contrasting plant communities in this region. The increase in yearly mean summertime amounts of rainfall, combined with the rise of yearly mean winter temperatures over the last years were conducive to changes in the spatial structure of vegetation. The boundary between the types of vegetation undergoes smoothing. The upper boundary of forest is altered because of changes of the environment that are responsible for the zonality and properties of vertical zonality of the vegetation on the mountains surrounding Lake Baikal. Changes in the vegetation serve as indicators of climate change as well as providing diagnostic tools for the genesis of the Baikal region’s natural environment.

Phytocenoses in the ecosystems contact zones are characterized by a rather complex structural and dynamical more than one features and by specific development characters under definite physical and geographical conditions. Unlike zonal vegetation, such phytocenoses respond to all environment changes more rapidly. The structure of such phytocenoses allows to determine the way this or that scenarios of climate change would develop at any level of more than one ecosystems. A possibility to use the notion “paragenese” for characterization of phytocenoses under contrast conditions is considered. Paragenese is the development of phytocenoses which are not related to zonal vegetation types by their composition and structure. Probably, the communities from ecosystems contact zones are to be related to a particular “type” of vegetation. Phytocenoses in the contact of light coniferous taiga and extrazonal steppes, as well as relations between zonal forest-steppe at main areas of Lake Baikal basin served as examples for justification of use of the notion “paragenese” to characterize the development of such communities.

Driven partly by cyber-security issues there is growing interest in modelling epidemics on networks. However it turns out that there are some gaps in the formulation of these network models that have precluded a proper study of stochastic fluctuations. The author revisits some popular models,rectify their shortcomings and then develops an asymptotic analysis of their behaviour.

The concept of Supply Chain 4.0 represents a transformative phase in supply chain management through advanced digital technologies like IoT, AI, blockchain, and cyber-physical systems. While these innovations deliver operational improvements, the heightened interconnectivity introduces significant cybersecurity challenges, particularly within military logistics, where mission-critical operations and life-safety concerns are paramount. This paper examines these unique cybersecurity requirements, focusing on advanced persistent threats, supply chain poisoning, and data breaches that could compromise sensitive operations. The study proposes a hybrid cybersecurity framework tailored to military logistics, integrating resilience, redundancy, and cross-jurisdictional security measures. Real-world applicability is validated through simulations, offering strategies for securing supply chains while balancing security, efficiency, and flexibility.

Objective: Physical assessment is an indispensable and pivotal skill that nurses must aptly monitor, evaluate, and deliver timely care, particularly in the context of critically ill patients. However, studies have revealed instances where nurses demonstrate inaccurate practices. This study is aimed to measure the physical assessment skills of critical care nurses and the differences between levels of nursing education. Methods: A descriptive cross-sectional study was conducted involving a simple random sample of 101 nurses employed in critical care units. Results: Of the 101 participants, 56.4% were identified as female and 43.6% were male. In the sample, 71.0% held a diploma in nursing, while 29.0% held a Bachelor of Science in Nursing (BSN). Vital signs, orientation, and skin assessments were performed correctly in ≥90% of cases, whereas the majority (≥60%) did not correctly assess neck veins, Homan’s signs, breath sounds, heart sounds, and bowel sounds. Only ≤10% of participants accurately executed these assessments. Significant associations were found between sex and pain (P=0.034), as well as between the type of education and closure of the health assessment (P=0.041). Further, female nurses scored 10.0 ± 2.3, and male nurses 8.5 ± 2.5, diploma holders scored 9.4 ± 1.8, and BSN holders scored 9.3 ± 2.7 at the global rating. Conclusions: The presence of an existing gap in the accurate assessment of patients poses a potential risk to patient care. It is essential to investigate the factors contributing to this gap and to develop strategies to address it, thereby enhancing the quality of physical assessment and ultimately improving patient care.

Optical resonators are a powerful platform to control the spontaneous emission dynamics of excitons in solidstate nanostructures. We study a MoSe2-WSe2heterostructure that is integrated in a cryogenic open optical microcavity to gain insights into fundamental optical properties of the emergent interlayer excitons. First, we utilize a low-quality-factor planar open cavity and investigate the modification of the excitonic lifetime as on-and offresonance conditions are met with consecutive longitudinal modes.

Production of this crop is experiencing significant challenges, resulting in a decline in seed and fiber quality. To address this challenge, generations of high-performance cotton plants of the Gossypium hirsutum L. species have been developed and are currently being commercialized. This study evaluated the impact of gin types on the agro-industrial quality of cotton in Côte d’Ivoire. To this end, cotton from the G3, R1, and R2 generations was harvested, sampled, and ginned on machines with 10 and 170 saws in the localities of Ouangolodougou, Ferkessédougou, Korhogo, M’Bengué, Boundiali, Séguéla, and Mankono, as well as at the Centre National de Recherche Agronomique CNRA) in Bouaké. The results demonstrated that cotton fibers obtained from ginning on 10-saw machines exhibited superior quality compared to those from 170-saw machines. Fiber length, fiber length uniformity, and short fiber rate exhibited the highest deviations according to gin type. The use of 170-saw gins resulted in a notable decline in quality. Conversely, micronaire index, fiber tenacity and elongation, and reflectance remained consistent across machine types. These results will enable us to more effectively regulate and advise cotton-processing factories, which primarily utilize 170-saw gins to enhance agro-industrial quality in Côte d’Ivoire. Furthermore, these results will assist breeders in incorporating them into their processes to enhance the quality of the varieties they offer to farmers.
