Performance analysis of UAV-enabled dual-hop mixed RF-FSO communication systems with user scheduling
Authors: Latka Deepika , Aggarwal Mona , Ahuja Swaran 
Published: December 2024

Abstract
Using UAVs as relays in wireless communication offers several advantages like flexibility, coverage, line-of-sight communication, cost effectiveness, adaptability to changing network demands, etc. UAVs can perform surveillance, delivery, mapping, and disaster response. They offer real-time data collection, high maneuverability, and access to remote areas. In this manuscript, we consider a UAV-enabled dual hop mixed RF/FSO wireless communication system. The system includes a UAV acting as a decode-and-forward relay, facilitating communication from the base station (B) to multiple mobile users. The opportunistic scheduling scheme is used to select the user with the best instantaneous channel conditions, typically based on the highest signal-to-noise ratio (SNR) or lowest outage probability, to maximize throughput and ensure more reliable communication. The first hop from B to the UAV relay R, employs a free space optics (FSO) link modeled with gamma–gamma fading. The second hop, from R to multiple users, is a radio frequency (RF) link modeled with Rayleigh fading. The direct communication between base station and mobile users is not possible due to the blockage by various natural and man-made obstacles. We analyze the outage probability at high SNR values to gain further insights into system performance. Additionally, closed-form analytical expressions for the outage probability and average bit error rate (ABER) of the proposed system are derived.

Published: December 2024

Abstract
In large-scale tiled chip multiprocessors (TCMPs), network-on-chip (NoC) is a prevalent interconnect solution. The NoC router plays a crucial role in NoC architecture, and two primary types exist: buffered and bufferless. The latter offers a promising solution due to its streamlined design, reduced energy consumption, and hardware efficiency. This paper proposes a 2D 4 × 4 mesh NoC architecture with a novel bufferless NoC router design using XY routing algorithm. The proposed mesh network consists of routers and processing elements, with each router connected to its four adjacent peers (North, South, East, and West) and a single processing element. The proposed router design eliminates the input buffers, output buffers and crossbar switch. The novel bufferless NoC router architecture comprises of various functional blocks, including ejection and injection controllers and Data ranking based on port prioritization, and age incrementor which efficiently solves long critical path issues by dynamically changing the port priority and hence solves the deadlock issue. By leveraging efficient routing and prioritization mechanisms, the novel architecture facilitates the seamless flow of flits through the network. Optical NoCs are based on optical interconnects and optical routers, and have significant bandwidth and power advantages. Our results indicate that the proposed bufferless router can lead to significant area (30.3 %) reduction over the standard BLESS.

Abstract
Loose finds associated with the LBK have long been recovered during surveys in the Warsaw Basin, Mazovia. Most often, they have been interpreted as remnants of short stays of LBK communities migrating northwards along the Vistula River, or as stopping points of expeditions southwards for flint. Rescue excavations at Cząstków Polski site XII, Czosnów commune, although carried out on a small scale, provide the first possibility of a comprehensive multiproxy analysis to test this hypothesis and determine the nature of the settlement. By integrating the results of the analysis of natural conditions (soils, hydrography), excavated features, and artefacts: pottery (technology, stylistics, petrography), flint (raw materials, typology, use-wear) and coarse-grained stone (raw materials, typology, use-wear), we show that the site actually represents the remains of a small, shortly used settlement that is part of a small contemporaneous settlement micro-region occupied during the beginnings of the middle LBK (early Music Note phase). This micro-region is an example of a peripheral, short-lived and thus unsuccessful colonisation of early farming communities associated with the LBK.

Abstract
In this study, we conduct a comprehensive investigation of the novel characteristics of the (2 + 1)-dimensional stochastic Hirota–Maccari System (SHMS), which is a prominent mathematical model with significant applications in the field of nonlinear science and applied mathematics. Specifically, SHMS plays a critical role in the study of soliton dynamics, nonlinear wave propagation, and stochastic effects in complex physical systems such as fluid dynamics, optics, and plasma physics. In order to account for the abrupt and significant fluctuation, the aforementioned system is investigated using a Wiener process with multiplicative noise in the Itô sense. The considered equation is studied by the new extended direct algebraic method (NEDAM) and the modified Sardar sub-equation (MSSE) method. By solving this equation, we systematically derived the novel soliton solutions in the form of dark, dark-bright, bright-dark, singular, periodic, exponential, and rational forms. Additionally, we also categorize and analyze the W-shape, M-shape, bell shape, exponential, and hyperbolic soliton wave solutions, which are not documented by researchers. The bifurcation, chaos and sensitivity analysis has been depicted which represent the applicability of the system in different dynamics. These findings greatly advance our knowledge of nonlinear wave events in higher-dimensional stochastic systems both theoretically and in terms of possible applications. These findings are poised to open new avenues for future research into the applicability of stochastic nonlinear models in various scientific and industrial domains.

Development of hemp seed (Cannabis sativa L.) beverages: Roasting effects and safety
Authors: Pugliese A. , Kakisu E. 
Published: December 2024

AbstractThe aims of this study were to formulate 2% and 3% (w/v) hemp seed beverages and to evaluate chemical composition, colloidal stability, safety, and sensory profiles after roasting the seeds (150 °C, 15 min). Beverages with 2% and 3% roasted hemp seeds evidenced acceptable sensory attributes and nutritious profile, containing 0.6–1% protein, 0.4–0.6% dietary fibre, and 0.5–0.8% lipids –mainly unsaturated fatty acids–, respectively. The roasting treatment significantly increased the phenolic content by 49–55% and the antioxidant capacity by 15%, and improved the sensory attributes of the beverages. Low peroxide levels (<1 meq O2/kg) in roasted hemp seed beverages were detected up to five days in cold storage, with better capacity against oxidation at 2% seed content. The use of 0.03% gellan gum improved the physical stability of suspensions contributing to their overall acceptability. Roasted hemp seed beverages showed no cannabinoid and tetrahydrocannabinol (THC) content. The advantages observed after roasting the seeds on phenolic content, antioxidant activity, sensorial acceptability and safety provided better attributes for the feasibility of beverages formulated with hemp seeds. The results showed a formulation suitable for the development of potential industrial roasted hemp seeds beverages with promising compositional profiles.

Aim. To justify a change in activities of a district nurse and the expansion of her clinical role.Material and methods. An analysis of regulatory legal acts governing the organization of primary health care and the activities of a district nurse was conducted. A medical and sociological study was conducted — an anonymous questionnaire of district general practitioners, district nurses, patients and observations of the work of district general practitioners and district nurses in parallel in order to assess the activities of a district nurse in the current situation. Based on analysis of the data obtained, organizational solutions were developed with a change in the activities of a district nurse. An organizational experiment was conducted. The following methods were used: analytical, statistical, content analysis, organizational experiment.Results. An analysis of regulatory legal acts showed that the functions of a district nurse include the implementation of a wide range of activities, but in practice many of them are not implemented. According to the survey results, the main functions of a district nurse were informing patients and inviting them to preventive measures (this function was noted by 90,8% of doctors and 99,0% of nurses) and preparing medical documentation at an appointment with a doctor (this function was noted by 85,5% of doctors, 94,3% of nurses and 45,4% of patients), which confirmed the results of observations. The organization of independent nursing appointments allowed to increase the effective time of the district nurse’s work with patients during an outpatient appointment from 14,2 to 49,5% and during a shift from 12,3 to 20,8%, as well as to reduce the functionally idle time during an outpatient appointment from 13,8 to 0% and during a shift from 10,7 to 2,4%.Conclusion. Changes in the activities of the district nurse contribute to an increase in its importance in the formation of a healthy lifestyle of the population, in the prevention of noncommunicable diseases and is a promising direction for improving primary health care. In matters of ensuring the availability of healthcare care, the professional competencies of the nursing staff should be taken into account.

Published: December 2024

Introduction. Communication and collaboration skills are very important skills in learning. These skills help students achieve learning success; however, many students have low collaboration and communication skills in schools.Aim. The present research aimed to demonstrate the potential of the PLONG (Playing, Learning, Doing, and Evaluating) learning model in developing students’ communication and collaboration skills.Methodology and research methods. This research applied the ADDIE model, which encompasses needs analysis, model design, material and activity development, field implementation, and evaluation. The study involved 101 students and 10 classroom teachers as participants. The instruments employed included model feasibility assessments, a PLONG model group discussion forum, and a questionnaire measuring collaboration and communication skills. Data analysis incorporated both qualitative and quantitative methods.Results and scientific novelty. It has been established that the PLONG learning model effectively enhances students’ communication and collaboration skills. These results are supported by an analysis comparing preand post-intervention data. This model increases students’ motivation and readiness to work collaboratively in teams. The novelty of this study lies in the fact that the PLONG learning model is regarded as a comprehensive approach to education, allowing students to independently assess their learning outcomes during the process, which includes engaging game elements. Additionally, PLONG offers feedback that aids students in their improvement.Practical significance. With the PLONG model, students engage in play, learning, action, and assessment, fostering an active and enjoyable learning environment that promotes the optimal development of collaboration and communication skills.

Published: December 2024

one of the Gram-Negative pathogens, serves a crucial organism in nosocomial outbreaks. The properties of this bacteria including adaptability, biofilm formation, etc. make this organism develop resistance against various antibiotic drugs. The current study aims to screen the multidrug resistant isolates for biofilm formation and to study the relationship of drug resistance and development of biofilm. Clinical samples growing in culture were screened for antibiotic susceptibility pattern using disc diffusion method. The multidrug resistant isolates of identified using culture and standard microbiological tests were included in the study and were tested for biofilm formation using micro titre plate assay: Out of the 224 clinical samples growing in culture, 100 isolates were found to be multidrug resistant (MDR). 42% of the isolates showed resistance to Cefepime followed by 26% isolates were resistant to Levofloxacin. 88% of the MDR isolates produced biofilm and among these 75% produced strong biofilm, 10% of the isolates produced weak biofilm and 3% of the isolates produced moderate biofilms. The present study observed that majority of the MDR isolates were found to be biofilm producers. Thus, biofilm production is said to be one of the important properties of the organism which could be attributed to their multi drug resistance.

Melatonin exchange in infertile women with repeated implantation failures
Authors: Nosenko O.M. , Demydchyk R.Y. 
Published: December 2024

Background. Repeated implantation failure occurs in approximately 10–15% of women undergoing in vitro fertilization and embryo transfer (IVF-ET) cycles. One of the important factors is the changed morpho-functional state of the endometrium and chronodestruction in the woman’s body.
Objective of the study: to determine the characteristics of melatonin (MT) metabolism in infertile women with repeated implantation failures in IVF-ET cycles.
Material and methods. 103 women of reproductive age with infertility and repeated implantation failures who were treated in IVF-ET cycles were observed. Depending on the onset of pregnancy in the current IVF-ET cycle, women were divided into 2 groups: group A – 35 women with the onset of pregnancy, group B – 68 patients without the onset of pregnancy. The control group (group C) included 32 healthy fertile women. The MT level in blood serum and 6-sulfatoxymelatonin (aMT6s) in urine was determined.
Results. The initial levels of MT in patients of group A (11.38 ± 0.38 pg/ml) and in group B (9.55 ± 0.27 pg/ml) were lower than in group C (13.67 ± 0.65 pg/ml) in 1.20 (p < 0.01) and 1.43 (p < 0.01) times, respectively. At the same time, the level of MT in women of group A was 1.19 times higher than in the group B (p < 0.03). Excretion of aMT6s in urine in group A (5.09 ± 0.19 ng/ml Cr) and in group B (3.03 ± 0.09 ng/ml Cr) were lower than in group C (6.12 ± 0.21 ng/ml Cr) respectively in 1.20 (p < 0.01) and 2.02 (p < 0.01) times. The aMT6s concentration in urine in patients of group A was 1.68 times higher than in group B (p < 0.01). A direct relationship was established between the levels of serum MT and urinary aMT6s, which was most adequately approximated by a polynomial dependence: y = 0.0139x2 – 0.1127x + 3.2978, R² = 0.2994, r = 0.51, p < 0.01.
Conclusions. Women with repeated implantation failures are characterized by a decrease in the level of MT in blood serum and its main metabolite aMT6s in urine, which may be one of the key factors of implantation failure.
