Published: January 2023

In this paper, we consider an unmanned aerial vehicle (UAV)-enabled massive multiple-input multiple-out (MIMO) non-orthogonal multiple access (NOMA) full-duplex (FD) two-way relay (TWR) system with low-resolution analog-to-digital converters/digital-to-analog converters (ADCs/DACs) architecture. Minimum mean-square error (MMSE) channel estimator and maximum ratio combining/maximum ratio transmission (MRC/MRT) at the UAV are utilized to obtain the UAV-GUs channel state information (CSI) and process the signals of multi-pair ground user (GUs), respectively. By adopting the additive quantization noise model (AQNM), the approximate sum spectrum/energy efficiency (SE/EE) with imperfect CSI and imperfect successive interference cancellation (SIC) are derived. To evaluate the effects of the parameters on system performance, the asymptotic analysis is presented. Then, the power scaling laws are provided to characterize the asymptotic performance. The numerical results verify the accuracy of theoretical analysis and show that the interference and noise can be effectively eliminated by deploying large-scale antennas, lager Rician factors, and applying proper power scaling law. We also find that the proposed system can obtain better SE performance by adjusting the height of the UAV. Moreover, the performance of the proposed system is related to the ADCs/DACs quantization bits, where the SE saturate values increase with the increasing number of quantization bits, while the EE first increases and then decreases. Finally, the SE/EE trade-off of this low-resolution ADC/DAC quantized system can be achieved by choosing the appropriate number of quantized bits, and the trade-off region grows as Rician factor increases.
Master Data Management using Machine Learning Techniques: MDM Bot

Published: January 2023

In today’s world of loosely coupled and distributed applications, communication and data centralization play a vital role. In large organizations, there are many applications and many teams that work on the data of customers, products, suppliers, and other business entities. Each application and team maintain a separate copy of the data, which means any application requiring this information needs to contact several other systems to obtain the most recent data for that entity. Therefore, this would increase the number of multiple lookups on various systems, resulting in an increase in the throughput of the application. To avoid this, the organization needs a centralized system called ”Master Data Management” that will maintain all the golden data across all the systems within the organization. Any system that is updated with new information will also be sent to MDM through events, and MDM will then be responsible for communicating with and updating the sub-systems within the organization’s Eco-System. Event-Driven Architecture will be used to communicate between distributed applications to achieve and implement Master Data Management. In recent years, there have been a lot of issues discovered in the MDM System between the data sync-up of all the sub-systems, resulting in a tedious process of identifying manually all the failures of the events, reprocessing the event  information, correcting the data,and re-synchronizing the other sub-systems with all the previous ones. To avoid this manual process and to address the issues mentioned above, we introduce the ”MDM Bot” in this article. Artificial Intelligence and Machine Learning capability are included in the proposed MDM Bot.It is an excellent value-added Bot for an Enterprise System that helps and saves a lot of time and money.

When fully implemented, sixth generation (6G) wireless systems will constitute intelligent wireless networks that enable not only ubiquitous communication but also high-accuracy localization services. They will be the driving force behind this transformation by introducing a new set of characteristics and service capabilities in which location will coexist with communication while sharing available resources. To that purpose, this survey investigates the envisioned applications and use cases of localization in future 6G wireless systems, while analyzing the impact of the major technology enablers. Afterwards, system models for millimeter wave, terahertz and visible light positioning that take into account both line-of-sight (LOS) and non-LOS channels are presented, while localization key performance indicators are revisited alongside mathematical definitions. Moreover, a detailed review of the state of the art conventional and learningbased localization techniques is conducted. Furthermore, the localization problem is formulated, the wireless system design is considered and the optimization of both is investigated. Finally, insights that arise from the presented analysis are summarized and used to highlight the most important future directions for localization in 6G wireless systems.
Zero-effort Continuous Two-factor Authentication
Authors: AlQahtani Ali Abdullah S. , Gourd Jean
Published: January 2023

Traditional two-factor authentication (2FA) systems often require users to enter a code or use a physical token, which can be inconvenient or inconvenient. In this paper, we propose a novel zero-effort 2FA system that utilizes the characteristics of ambient access points (APs) visible to users’ devices to authenticate them without requiring user interaction. The proposed system is flexible and adaptable, allowing for the adjustment of various parameters such as the range of acceptable distances between the user’s devices and the minimum number of APs required for authentication. It is also robust, with features to handle situations where there may be a lack of APs in the user’s environment or the user does not have access to their mobile device. Additionally, the proposed system takes user privacy into consideration by limiting the storage of sensitive information and purging data related to a user’s session after it is complete. The proposed system is a secure and user-friendly solution for 2FA that can be easily implemented in various settings. Finally, the proposed system was tested and evaluated, and the results showed that it is effective in authenticating users while maintaining a high level of security.

Business models can be a perfect tool to meet the challenges in highlighting the competitiveness and sustainability potential of bio-based solutions, and facilitating primary producers to benefit from the opportunities offered by bioeconomy. In this work six concrete bio-based good practices that have succeeded in progressing from early ideas to products on the market were analysed. These examples pose new insights that can be used by a wide range of experts and stakeholders for the analysis of benefits and challenges of value chains in the bio-based economy sectors. It is concluded that the traditional Business Model Canvas needs to be extended with additional factors related to sustainability and business ecosystem. In order to establish a practical framework promoting economic viability of bio-based business cases, the importance is highlighted for adjusting the exclusive focus on Technology Readiness Levels by introducing levels reflecting business or market readiness.
A choice model-based analysis of diversification in organic and conventional farms
Authors: Bonfiglio Andrea , Abitabile Carla , Henke Roberto
Published: January 2023

Diversification is a polymorphic strategy to increase agricultural income and reduce the risks deriving from the surrounding environment. This strategy can also be successfully adopted in the context of organic farming. However, there is a lack of confirmation in this regard given the scarcity of studies that explicitly focus on diversification in organic farms. The objective of this paper is to analyse the influence of some territorial, socio-economic, and political factors on the probability of diversifying in both organic and conventional farms. To this aim, multinomial and binary logit models are applied to the Italian case. Results suggest that on-farm diversification requires specific competences and adequate organization. However, the reasons for diversifying differ depending on the production model. In conventional farming, farmers diversify to achieve income levels comparable with those of a more competitive agriculture. Conversely, for organic farmers, diversification represents an integrated part of the production model to take advantage of synergies between organic production and diversification. From these results, some policy implications are drawn.

Published: January 2023

This paper aims to overview the recent body of empirical work on the importance of Global Value Chains (GVCs) in international production and trade. We begin by reviewing different approaches and levels of GVC analysis. We then consider developments in methods and data. Focusing on the agriculture and food sector, we present a map of GVC measures - at the country and sectoral level - computed using trade in value added data to allow researchers to better assess the countries’ engagement in GVCs. We also apply this data to show some stylized facts on GVC participation and positioning in agriculture and food and provide empirical evidence of the economic impact of the GVCs on these sectors. We conclude with some critical issues and speculative thoughts regarding the future of GVCs.

Introduction

We aimed to identify clinical, pathologic, and treatment factors that are predictive of response and survival in patients with cervical cancer referred to phase I clinical trials.

Methods

Patients with cervical cancer who received at least one dose of a phase I investigational agent at our institution between 2014 and 2022 were included. The log-rank test was used to analyze differences in progression-free survival (PFS) and overall survival (OS), and multivariable regression analysis was performed.

Results

We included 65 patients with a median age of 41 years (range, 20–74), 3 prior therapies (range, 1–7), and 67.7% squamous carcinoma. The rate of distant metastasis at trial entry was 84.6%. The most common molecular alterations included PIK3CA (46.5%), PD-L1+ (46.2%), EPH (30.0%), and CREBBP (23.1%); 23.1% had received a prior checkpoint inhibitor. Phase I trials were for immunotherapy (58.5%) or targeted therapy (41.5%). The rate of biomarker matching was 21.5%. For all patients, median PFS was 3.6 months (95% CI, 2.0–5.2) and OS was 9.3 months (95% CI, 7.0–10.6). Factors at study entry associated with worse survival were presence of bone metastasis (PFS 1.6 vs 4.4 months: hazard ratio [HR], 2.8; p = 0.001; OS 3.8 vs 10.0 months: HR, 3.9; p < 0.0001) and absolute lymphocyte count below 1000/μL (PFS 1.8 vs 5.2 months: HR, 2.9; p = 0.0004; OS 7.0 vs 10.6 months: HR, 3.2; p = 0.0009). Factors associated only with worse OS were absolute neutrophil count above 4700/μL, hemoglobin below 10.5 g/dL, and smoking status. Grade 3+ treatment-related adverse events were seen in 16.9% of cases.

Conclusion

Bone metastasis and absolute lymphocyte count below normal range at phase I study entry portend poor survival in patients with recurrent or metastatic cervical cancer.

Published: January 2023

Goal. To establish the multi-year dynamics of the number of the main pests of winter wheat and the indicator of entomological diversity of agricultural landscapes in the conditions of climate change in Ukraine.

Methods. Laboratory, statistical and analytical. The state of populations during 2005—2017 was studied using the example of an indicator group of species — the entomological complex of the main pests of winter wheat crops. As initial data, a long-term database of the number of populations of the entomocomplex in different natural and climatic zones, which is monitored by specialists of the phytosanitary safety department of the State Production and Consumer Service of Ukraine, was used for many years.

Results. According to the analysed data on the state of indicator populations during 2009—2017, the indicators of the population size and weighted LPI were constantly decreasing. The correlation between the size of an insect’s population and the course of natural warming does not make it possible to unambiguously explain the state of populations by the effect of an increased amount of heat.

Conclusions. 1. The analysis of the long-term state of populations of a harmful entomocomplex of winter wheat as an indicator group shows that pests react differently to warming depending on the biology of the species and allows us to come to a conclusion about the gradual decrease in the number of insects in agricultural landscapes under conditions of climate warming in Ukraine. This finding is in good agreement with the literature on global depletion of invertebrate populations. 2. Under the conditions when most species of the harmful entomocomplex of winter wheat in different natural and climatic zones of Ukraine show depression against the background of global warming, planned chemical treatments against pests should be carried out only after careful phytosanitary monitoring of agrocenoses in order to clarify the degree of threat to the crop, which will help reduce pesticide load on the natural environment.

Authors: Kuzmenko N.
Published: January 2023

Goal. To study the population and harmfulness of intrastalk pests in the agrocenosis of spring barley depending on the use of fertilizers.

Methods. The investigations was carried out in a stationary field, fixed nine-course-fallow-grain-row crop rotation at the Department for Plant Production and Cultivar Investigations of the Plant Production Institute named after V.Ya. Yuriev of the National Academy of Sciences (Eastern Forest-Steppe of Ukraine) during 2011—20.

Results. During the years of research, the species composition of intrastalk pests was represented by: Oscinella pusilla Mg., O. frit L., Chaetocnema hortensis Geoffr., and Mayetiola destructor Say. Oscinella pusilla Mg. and O. frit L. dominated, damage to shoots by their larvae varied from 1.9% (2016) to 61.1% (2013). Damage to shoots by Chaetocnema hortensis Geoffr. larvae ranged from 0.4% (2015) to 35.5% (2011). The greatest damage to shoots by the larvae of Mayetiola destructor Say. was registered in 2018 — 5.7%. Application of fertilizers (manure 6.6 t/ha of the crop rotation area, aftereffect, and mineral fertilizers in the norm N30P30K30 or N45P45K45) provided increased resistance of spring barley plants to damage by pests. On the average over 2011…2020 year period, in the block without fertilizers, damage to shoots by Oscinella pusilla Mg. and O. frit L. larvae was 21.6%, in the fertilized block — 19.3% (decrease at the tendency level). At the tillering stage, the undamaged shoots on the background without fertilizers was 72.5%, on the fertilized background — 76.1% (difference at the tendency level). A reliable converse average correlation was established between the damage of shoots by intrastalk pests and the grain yield of spring barley (r = –0.5). Averaged over ten years, the grain yield in the block without fertilizers was 3.25 t/ha, with the application of fertilizers — 4.69 t/ha, there was a difference of 30.7%.

Conclusions. The positive role of fertilizers in regulating the number of intrastalk pests of spring barley and increasing grain yield was established.

Published: January 2023

Goal. To determine the spread and development of pests and diseases in sugar beet crops and their threat to crop plants.

Methods. Analysis of the reports of regional forecasting and signaling laboratories of the State Vetphytosanitary Service of Ukraine and the results of own observations conducted at research and breeding stations of the Institute of Bioenergy Crops and Sugar Beet of the National Academy of Sciences of Ukraine and beet farms of Ukraine regarding the prevalence and development of phytophages and pathogens, their reservation in agrocenoses. Determination of the threat from them to crops according to the Methodology of research in entomology and phytopathology and the Methodology of conducting research in beet growing.

Results. It was established that certain types of pests have a significant reservation in agrocenoses and other stations and annually threaten sugar beet crops in various beet harvesting zones. In particular, from year to year, the greatest danger to crop seedlings and plants during their growing season is caused by beetles of the common beet weevil Asproparthenis punctiventris (Bothynoderes punctiventris Germ.), the number of which significantly exceeds the economic threshold of its harmfulness. Among other types of harmful insects that annually threaten sugar beet crops, the gray beet weevil (Tanymecus palliates F.), beet fleas (Chaetocnema sp.), shieldworms (Cassida sp.), stem weevil (Lixus sultilis Beh.) will be dangerous in future years.), the number of which varies within the thresholds of their harmfulness. Regarding diseases, there is still a threat of significant damage to culture plants by cercospora (Cercospora beticila Sacc.), fomosis (Phoma betae Frank), powdery mildew (Erysiphe communis (Wallr Grev f.betae Jacz.)), and others. In particular, according to observations, cercosporosis is gaining pace of intensive development due to favorable weather conditions, so we recommend farms to take measures to reduce plant damage. Precipitation, which passes through centers at the end of summer in most regions of Ukraine, can lead to significant susceptibility of root crops to various types of rot, which can also lead to a decrease in crop yield and quality deterioration.

Conclusions. In recent years, favorable conditions have been created in Ukraine for the development and spread of many types of pests and diseases in sugar beet crops, which leads to an increase in their harmfulness compared to previous seasons. In particular, the population density of beetles of the common beet weevil was 2—18 specimens/m2, which is ten times higher than the standard. The same applies to other pests and diseases, a significant reserve of which may threaten crops in the coming year.

Clinical sociology offers an approach that breaks with the paradigms stemming from the engineering  and management sciences. The clinical approach is critical in the face of normative, quantitative, prescriptive approaches dominated by instrumental rationality and the commodification of human relations. She is interested in the singular, in subjectivity, in experience, in the sensitive, with an ethical concern. Its objective is to associate the actors concerned with the understanding of the problems, to involve them as subjects in the elaboration of the answers that they bring individually and collectively to the contradictions which cross them. She does not seek to model reality but to immerse herself in lived experience, as close as possible to concrete situations, the reality of work, the subjective apprehension of the problems encountered. It is part of a complex social system. Change is not prescribed, it is built in a process that involves, actively or passively, all the people concerned.
