Downlink Power Control: A Performance Booster for Full Duplex Cellular Networks

<div><div>Full duplex (FD) communication uses the same time-frequency resource elements for uplink and downlink transmissions. Compared to half-duplex (HD) systems, this improves the effective spectrum usage, but at the cost of additional self-interference and increased co-channel interference (CCI). Promising improvements in full duplex downlink performance are well established in the literature, but the improvement in uplink is marginal or even severely degraded due to strong down-link signals. This paper focuses on managing CCI in an FD network by spatially controlling downlink and uplink transmit powers. We show that uplink performance can be improved through the introduction of downlink power control, but this slightly reduces downlink performance. We introduce a distance-based user scheduling to address this reduction. Furthermore, we have also shown that optimal overall performance can be achieved by designing appropriate uplink and downlink power control factors. We used the Matern Cluster process to model the network. The analytical results we formulated is verified by extensive Monte Carlo simulations. This work is submitted to IEEE transaction on Wireless Communications. Currently it is under review.</div></div>

Spatial Distribution and Geographical Mechanism of Natural Resources in China under the Orientation of the New Economic Demands

The demand structure of resources for new economy is different from the traditional one in that its development may significantly change China’s economic location map and spatial pattern. Based on 343 administrative units of prefecture-level cities in China, this research constructs the measurement index system of terrestrial surface natural resources under the orientation of the new economic demands; this research mainly analyses the spatial distribution characteristics and geographical mechanism of natural resources by means of the spatial autocorrelation and spatial similarity calculation methods. The results show that: (1) The structure and endowment of natural resources under the orientation of the new economic demands need to be reexamined. The significance of a good environment and ecological resources has been highlighted. The coupling of resource elements better reveals the availability of natural resources. (2) The natural resources decrease from southeast to northwest, showing a pattern of “abundant in the south and east and scarce in the north and west”. Natural resources have a significant positive correlation in spatial distribution with two types of agglomeration: high-high agglomeration and low-low agglomeration, showing the local agglomeration feature of “high in the south and low in the north”. (3) Natural factors such as temperature, precipitation and altitude affect the spatial distribution of natural resources, with the temperature being the most significant. This indicates that the original natural environment and its role are the geographical mechanism for the formation and distribution of natural resources. The results could provide a reference for the development and the optimization of China’s new economy.

Decisions on the Orderliness and Collaborative Operation Mechanism of Each Subsystem under the Organizational Model of the Internet of Things

This paper analyzes the overall organic network system integrated by subnetworks, analyzes the network evolution process of the overall system of the Internet of Things (IoT) organization mode network, and analyzes the network through the network scale measurement, the node growth measurement, the node distribution measurement, and the node association measurement. We analyze the coordination mode of hardware resources, information resources, financial resources, human resources, organizations, and customer resources from the perspective of resource elements. And we analyze the vertical and horizontal work collaboration mode from the perspective of work activities. From the perspective of equity, two types of equity-based synergy and four types of contract-based synergy are proposed. It is proposed that the network stage of the IoT organization model is different from the previous stage of the important collaboration model, the platform-based collaborative model, which is analyzed from the coordination manager software platform and the IoT organization model infrastructure hardware platform. We use relevant data to construct a SIM model to measure the synergy of the development of the IoT industry system to quantify the overall collaborative development status of the IoT industry system. At the same time, the gray correlation analysis model GM (1, N) is used to correlate the complex system subsystems. The research results show that the development of the IoT industry has gone through a U-shaped development process from the uncoordinated stage to the coordinated development of the industrial system. Each subsystem has self-development capabilities and exhibits different interaction relationships with each other.

Can FHIR Support Standardization in Post-Market Safety Surveillance?

The Fast Healthcare Interoperability Resources (FHIR) contain multiple data-exchange standards that aim at optimizing healthcare information exchange. One of them, the FHIR AdverseEvent, may support post-market safety surveillance. We examined its readiness using the Food and Drug Administration’s (FDA) Adverse Event Reporting System (FAERS). Our methodology focused on mapping the public FAERS data fields to the FHIR AdverseEvent Resource elements and developing a software tool to automate this process. We mapped directly nine and indirectly two of the twenty-six FAERS elements, while six elements were assigned default values. This exploration further revealed opportunities for adding extra elements to the FHIR standard, based on critical FAERS pieces of information reviewed at the FDA. The existing version of the FHIR AdverseEvent Resource may standardize some of the FAERS information but has to be modified and extended to maximize its value in post-market safety surveillance.

Standardizing Primary Healthcare referral datasets: Interviews, form-reviews, and FHIR profiling (Preprint)

BACKGROUND Referral linkages are crucial for efficient functioning of Primary Health Care (PHC) systems. Fast Healthcare Interoperability Resource (FHIR) is an open global standard that facilitates structuring health information for coordinated exchange amongst stakeholders. OBJECTIVE The objective of this study is to profile, present methodology and the profiled FHIR resource for Maternal and Child Health (MNCH) referral use case in a typical Low-and-Middle-Income-Country (LMIC). METHODS Practicing doctors, midwives, and nurses were interviewed, and different referral forms reviewed. In this study, we have introduced the FHIR and its relation to the WHO International Classification for Disease (ICD). The union of datasets were aggregated and mapped to base patient FHIR resource elements, and extensions were created for datasets not in the core FHIR specification. RESULTS We found that there were many different data elements from the referral forms and interview responses. The resulting FHIR standard profile is published on GitHub for adaptation or adoption as necessary. Understanding datasets used in healthcare and clinical practice for information sharing is crucial in properly standardizing information sharing particularly as the world manage COVID-19 and other infectious diseases. This methodology and profiled dataset can be used by development organizations, and governments to fast-track FHIR standards adoption for paper and electronic information sharing at PHCs in LMICs. CONCLUSIONS We presented our methodology for profiling the referral resource crucial for the standardized exchange of new and expectant moms’ information. Using data from frontline providers and mapped to the FHIR profile helped contextualize the standardized profile.

The Theoretical and Methodological Principles of Forming the Economic Security System of Industrial Enterprise

The article is aimed at improving the theoretical and methodological principles and formalizing the methodological provision of the processes of formation of a comprehensive system of economic security of industrial enterprises. The article analyzes the theoretical principles of interpretation and management of the economic security system of enterprises. In particular, it is defined that modern scientific define the economic security system as an aggregate of elements that provide protection along with threat assessment. The author proposes to consider the concept of «economic security system» as an aggregate of resource elements and functions for harmonization of interests, complexity, flexibility, interaction and coherence of space, which determines the economic efficiency of adaptability of units, management elements, subsystems and allows comprehensively and fully diagnosing risks and threats, potential deviations, as well as substantiating the cost of resources for the systematic provision of security of industrial enterprise. A functional-resource approach to the formation of the economic security system is substantiated. Internal incentives and motivators of the formation of the economic security system are formalized, which are disclosed through structural elements of the system and process flows in the internal environment of the enterprise. To activate the resource and functional elements, it is necessary to establish the goals of the system formation and formalize their species composition. This will allow to determine and substantiate the cost of security provision, minimization of risks and the instrumentarium of the organizational and economic security mechanism. The article describes elements of the security space, which include the resource and functional constituents, methodological means of diagnostics and regulation, as well as economic agents who are in contact with external actors. Motivators, strategic guidances and tasks of its development are defined as strategic elements of the economic security system. The formation of the economic security system of industrial enterprises should be based on the conceptual coordination of elements and functions in accordance with the subjective impact of the environment, as well as on strengthening innovation and integration processes and increasing the cost of preventive activities. The specified aspects are implemented through the instrumentarium of organizational management, which is formalized through the subjects, object, tasks and directions of ensuring economic security.
