Impact of China’s National Volume-Based Procurement on Drug Procurement Price, Volume, and Expenditure: An Interrupted Time Series Analysis in Tianjin
Authors: Zhao Boya , Wu Jing
Published: September 2023

Background: National Volume-Based Procurement (NVBP) program has been carried out in China to lower drug prices and reduce patients’ medication burden. This study aims to evaluate its impact on drug purchasing in Tianjin city, one of the first 11 cities piloting NVBP in China. Methods: Using monthly drug procurement data from Tianjin Medical Purchasing Center between 2018 and 2020, this study identified bid-winning drugs and their alternative drugs in the pilot NVBP, and evaluated the policy impacts on their procurement price (cost of defined daily dose, DDDc), volume (the number of defined daily dose, DDDs), and expenditure, during the first (initiated at April 1, 2019) and second (initiated at April 25, 2020) procurement cycles of pilot NVBP, applying interrupted time series (ITS) analysis. Included drugs were classified into 12 pharmacological subgroups for further analysis. Results: Decrease in DDDc of NVBP-covered drugs (bid-winning and non-winning drugs) were observed in the first (level change: -CNY 3.878/DDD, P<.001; trend change: -CNY 0.068/DDD, P=.001; relative change: -61.55%) and second (level change: -CNY 0.356/DDD, P=.049) procurement cycles of pilot NVBP, while no significant change was observed for the DDDc of alternative drugs, except for the increase in antidiarrheic and anti-inflammatory/antirheumatic subgroups as more expensive drugs were purchased from new suppliers in the second procurement cycle. The DDDs of bid-winning drugs significantly increased, while decreased for the non-winning original and generic drugs. Procurement expenditure was saved for NVBP-covered drugs (level change: -CNY 7.29×107, P<.001; trend change: -CNY 5.62×106, P<.001; relative change: -62.60%). However, during the second procurement cycle, procurement volume and expenditure of alternative drugs increased significantly in 7 out of 12 subgroups. Conclusion: The pilot NVBP policy in China reduced procurement price, promoted generic substitution, and saved procurement expenditure. However, the increase in procurement price, volume and expenditure of alternative drugs may reveal the significance of regulating healthcare institutions’ drug purchasing behavior.

The Memory of the Two Battles of the Batu’s Invasion Epoch
Authors: Рудаков В.Н.
Published: September 2023

Статья посвящена исторической памяти о двух сражениях эпохи нашествия Батыя на Северо-Восточную Русь – под Коломной и на реке Сити. В работе решается вопрос о том, почему подлинный герой сопротивления завоевателям – рязанский князь Роман Ингваревич и сражение под Коломной, в ходе которого монголам был нанесен внушительный урон, почти не запечатлелись в исторической памяти. Но при этом бой на реке Сити, история которой крайне туманно изложена в источниках, наоборот, стал одним из символов сопротивления монголам, а ее участник – великий князь владимирский Юрий Всеволодович, поступки которого в период нашествия Батыя были крайне противоречивы, остался в памяти потомков как едва ли не главный борец с захватчиками. Автор приходит к выводу, что подобная трактовка в свое время оказалась востребована составителем рассказа Лаврентьевской летописи, намеренно рассказывавшим о «своих» князьях в наиболее благоприятном для их памяти виде и умалчивавшим о «чужих». Впоследствии версия именно этой летописи легла в основу более поздних рассказов о событиях эпохи нашествия.

The article is dedicated to the historical memory of two battles of Batu's invasion to the northeastern Russia epoch – near Kolomna and on the Sit River. Why the true hero of resistance, Ryazan Prince Roman Ingvarevich and the battle of Kolomna, during which the Mongols suffered impressive damage, were not imprinted in historical memory? The article gives answer to that question. At the same time, the battle on the Sit River, the history of which is rather hazy described in the sources, became one of the symbols of the resistance against the Mongols, and its participant – the Grand Duke of Vladimir Yuri Vsevolodovich, whose actions during the Batu's invasion were extremely contradictory, remained in the memory of descendants as almost the main fighter against the invaders. The author comes to a conclusion that such a depiction of the events had been much affected by personal demands of the compiler of the Laurentian Chronicle, who deliberately told about «his» princes in the most favourable form and kept silent about «strangers». Subsequently, the version of this particular chronicle formed the basis for later stories about the events of the invasion epoch.

Authors: Vetitnev A. M. , Vorobey E. K. , Gvarliani T. E.
Published: September 2023

Aim. To propose measures to combat overtourism and its negative consequences at the global level and at the level of Sochi Destination.

Tasks. To study the processes and risks associated with overtourism; to use the term “overtourism” to describe the negative consequences of mass tourism, which, as a rule, are associated with the explosive growth of popularity of certain places in the world, attracting more and more attention from both ordinary tourists and social network users; to conduct the practical part of the study on the example of the resort city of Sochi.

Methods. In this article the international and domestic experience of levelling the risks of overtourism is investigated with the help of analysis, system approach and statistical methods. Measures to combat overtourism and its negative consequences both at the global level and at the level of Sochi destination are proposed.

Results. With the overall positive situation in the Sochi destination with signs of overtourism, the formation of its initial manifestations can be traced, which requires the development of preventive measures. In this case it is recommended to take into account the information of the Association of restaurateurs and hoteliers HOTREC, proposed to solve the problems of overtourism in European countries.

Conclusions. In the case of signs of overtourism detected by different assessment methods, regional tourism administrations should be advised to develop appropriate prevention strategies. It can be assumed that such strategies should be formed depending on the stages of the life cycle of the destination.

Authors: Minbaleev A. V.
Published: September 2023

Aim. To identify key problems and prospects for the development of legal support for the transformation of the Russian economy in the transition to a data economy in a multipolar world.

Tasks. To substantiate the role and significance of the transition to the data economy from the position of the multipolar world policy development; to identify the key directions of legal support for the formation and development of the data economy, as well as the solution of problems arising in this process.

Methods. The research was conducted on the basis of a set of general scientific methods (system analysis, method of dialectical cognition, etc.) and special methods (legal modeling, formal-legal, comparative-legal).

Results. The author has revealed the main regularities associated with the impact of the development of data economy on the foreign policy realized by the Russian Federation (RF) on the formation of a multipolar world. The necessity of proper legal support of these processes has been substantiated. The key directions of development of legal support, as well as the existing problems in this area are identified.

Conclusions. In modern conditions the policy of multipolar world pursued by Russia can be realized only under the condition of independence, including technological, and ensuring a high level of economic development of the state. The data economy allows already today to talk about the prospects for the development of new technological modes and markets of the future. The necessity of a comprehensive approach to the legal support of the formation and development of the data economy on the basis of systematization of Russian legislation in electronic form has been substantiated, which will greatly facilitate the task of identifying problems related to the quality of normative legal acts and increase the efficiency of law enforcement. In the process of systematization of modern legislation in order to effectively implement it in all spheres of management, it is important to establish general requirements for the functioning of systematization processes and the use of various information technologies. The adoption of the basic law on artificial intelligence, as well as the Digital Code of the Russian Federation is proposed. The problems related to their adoption and their content are highlighted.
Distributed Noncooperative MPC for Energy Scheduling of Charging and Trading Electric Vehicles in Energy Communities
Authors: Mignoni Nicola , Carli Raffaele , Dotoli Mariagrazia
Published: September 2023

In this paper, we propose a novel control strategy for the optimal scheduling of an energy community constituted by prosumers and equipped with unidirectional vehicle-to-grid (V1G) and vehicle-to-building (V2B) capabilities. In particular, V2B services are provided by long-term parked electric vehicles (EVs), used as temporary storage systems by prosumers, who in turn offer the V1G service to EVs provisionally plugged into charging stations. To tackle the stochastic nature of the framework, we assume that EVs communicate their parking and recharging time distribution to prosumers, allowing them to improve the energy allocation process. Acting as selfish agents, prosumers and EVs interact in a rolling horizon control framework with the aim of achieving an agreement on their operating strategies. The resulting control problem is formulated as a generalized Nash equilibrium problem, addressed through the variational inequality theory, and solved in a distributed fashion leveraging on the accelerated distributed augmented Lagrangian method, showing sufficient conditions for guaranteeing convergence. The proposed model predictive control approach is validated through numerical simulations under realistic scenarios. 

This preprint has been accepted for publication in IEEE Transactions on Control Systems Technology.

Power Transfer between Two Antenna Arrays in the Near Field
Authors: Tiwari Krishan Kumar , Caire Giuseppe
Published: September 2023

This letter presents numerical results with a focus on power transfer between two antenna arrays placed in the near field, where a much smaller active multi-antenna feeder (AMAF) center feeds a far larger passive array referred to as a reflective intelligent surface (RIS). The AMAF is configured along the principal eigenmode of the AMAF-RIS propagation matrix T. The interest is in the regime of f/D less than unity. The power transfer coefficient deviates from the classical distance dependent inverse square law model. This is due to the natural taper across the RIS aperture at such small f/D ratios. In addition, the behavior of the power transfer coefficient is more sensitive to the f/D ratio than to a specific RIS size. We also see that the center feed is more power efficient than end feed.

Authors: Harkous Hasanin , He Mu , Pries Rastin , Jarschel Michael , kellerer wolfgang , Hosn Bassel Aboul
Published: September 2023

The recent trend to deploy programmable packet processors in cloud environments enhances the packet processing capability without losing the flexibility to adapt the functions at runtime. In particular, distributed edge clouds can have a heterogeneous programmable processing substrate made up of different classes of devices: CPUs, NPUs, FPGAs, etc. However, managing the allocation of workloads in such a heterogeneous programmable processing substrate, in particular deciding where to instantiate a certain function, is a non-trivial task with many decisive functional and QoS-related factors. 

In this paper, we propose a mathematical model for optimizing the embedding of Service Function Chains implemented in P4, while considering the functional and QoS requirements associated with embedding requests, and the various types of processing devices that have different properties in terms of processing delay and supported features. To satisfy delay requirements, the problem formulation utilizes performance models to predict the forwarding latency associated with different candidate embedding options. Furthermore, a greedy solution is proposed to solve the problem in an efficient manner. Finally, a detailed numerical evaluation is conducted to evaluate the formulated model when different workload and infrastructure characteristics are varied and to evaluate the effectiveness of the proposed greedy solution.

Penalized Maximum Likelihood Based Localization for Unknown Number of Targets Using WSNs: Terrestrial and Underwater Environments
Authors: Al-Jarrah Mohammad Ahmad , Alsusa Emad , Al-Dweik Arafat
Published: September 2023

This paper proposes a multiple targets localization scheme using a clustered wireless sensor network (WSN) for terrestrial and underwater environments. In the considered system, sensors measure the total energy emitted by the targets and transmit quantized versions of their measurements to a data central device (DCD) with the assistance of intermediate cluster-heads (CHDs), which employ decode-and-forward relaying (DFR). Upon data collection from the sensors, the DCD performs the localization process, which involves estimating the number and positions of the targets. The data transmission from the sensors to the CHDs takes place through an imperfect medium, which is characterized by a Rician fading model. The penalized maximum likelihood estimator (PMLE), also known as regularized maximum likelihood estimation (MLE), is applied at the DCD to provide optimal estimates for the number and locations of targets. Furthermore, a suboptimal estimator is derived from PMLE, which can offer comparable performance under certain operating conditions with significantly reduced computational complexity. Cramer-Rao lower bound (CRLB) is derived to serve as an asymptotic benchmark for the root mean square error (RMSE) of the estimators in addition to the centroid-based localization benchmark. Monte Carlo simulation is used to evaluate the performance of the proposed estimation techniques under various system conditions. The results show that PMLE is an effective tool for estimating the number and locations of the targets. Additionally, it is demonstrated that the RMSE of the proposed estimation approaches the CRLB for a large number of sensors and high signal-to-noise ratio.

Authors: - Akanksha
Published: September 2023

Alterations in complex behavioural patterns during the extended period of the COVID-19 pandemic are predicted to promote a variety of psychiatric disease symptoms due to enforced social isolation and self-quarantine. Accordingly, multifaceted mental health problems will continue to increase, thereby creating a challenge for society and the health care system in general. Recent studies show that COVID-19 can directly or indirectly influence the central nervous system, potentially causing neurological pathologies such as Alzheimer disease and Parkinson disease. Thus, chronic COVID-19-related disease processes have the potential to cause serious mental illnesses, including depression, anxiety, and sleep disorders. Importantly, mental health problems can foster systemic changes in functionally-linked neuroendocrine conditions that heighten a person’s susceptibility to COVID-19 infection.

Authors: - Ellen Blessing Sobeng
Published: September 2023

The study sought to investigate the language judges use to assess performances of reality show contestants. It specifically examined the attitudinal evaluative language judges of Ghana’s Most Beautiful (GMB) show employ in their comments when assessing contestants’ performances. To realize the objectives set for the study, the appraisal framework by Martin and White (2005), which was developed within the broader theoretical framework of Systemic Functional Linguistics (SFL) and focuses on the interpersonal metafunction of language, informed the study. Fifty-two comments of four judges from six episodes of three seasons were recorded and transcribed for analysis. The study revealed that the dominant attitudinal resources used by judges as a means of evaluating contestants’ performances was judgement. Thus, while judges praise and admire, they criticize when necessary. Again, it was observed that the use of judgement as the dominant attitudinal device for evaluation appropriately reflected the purpose of GMB.
Healthcare Record Management Using Blockchain
Authors: - Pravesh Rana , - Parth Dahiya , - Nishant Suhag , - Jagrat Singh
Published: September 2023

Background. Blockchain has been in popular demand for the last decade or so, but it recently gained recognition with the popularity of Bitcoin. It has been extensively used in fields like finance, government, energy, etc. It is the need of the hour that the technology was utilized in other relevant areas as well like healthcare. Making maximum use of blockchain in the healthcare industry is expected to have numerous significant impacts and positive outcomes. The technology is defined as a decentralized and distributed ledger that can be used to record transactions securely across many computers in a peer-to-peer network, without the need for a third party.
Objectives. A block consists essentially of a header and a body. The header of each block contains the hash of the previous block. Among the important features of blockchain is how it is impossible to tamper with and is censorship resistant, giving access to the timestamped transaction while maintaining anonymity at the same time.
Methods. The method used is literature survey. We perform a study selection process in four steps. After each steps the number of publications is reduced as unwanted publications are omitted using search strings, inclusion and exclusion criteria. We even conducted a study quality assessment which helps us analysis the quality of findings from the final set of selected papers in answering the research questions.
Results. We have summarized the findings from the 10 selected papers from the study selection process according to the research questions.
Conclusions. The most prominent feature of blockchain technology is the fact that it removes the need for a centralized third party and makes it possible for two parties to carry out transactions without a centralized authority. It highly improves the transaction speed by removing any type of delay and makes the transaction cheaper as well. This project intends to explore how decentralization makes it easier to maintain transparent and open records for patients to see how, when, and where their information is being used. By employing the programming language Solidity, a smart contract will be created which will be deployed on the Ethereum blockchain. This in turn will further ensure that no recorded data can be deleted. Any data recorded by the doctor in the blockchain can be edited whereas the patients will only have viewing access to the entered medical records. This will not only ensure a high level of security, but also the credibility of the information provided.

Mapping of Cultural Heritage is a crucial process aiming at safeguarding and promoting the unique identity, history, and traditions of a particular community or region. This practice involves the documentation, conservation, and interpretation of various aspects of Cultural Heritage, which can be conducted through Geomatics techniques including the use of various tools and methods to collect, analyze, and visualize spatial data related to heritage sites. The same techniques can be used for the identification and subsequent cataloging of unsafe buildings thus creating a cadastre useful for authorities, urban planners, and building management organizations to identify, monitor and address unsafe structures. In this context, this paper presents an automatic, innovative, and experimental system through which it has been possible to map the Cultural Heritage in a fraction of the province of Reggio Calabria and, at the same time, to build a cadastre of unsafe structures. A prototype drone was programmed to acquire the images, subsequently pre-processed using commercial software and analyzed using Machine Learning techniques and dedicated software. An Open GIS (Geographic Information System), then, made it possible to view the archaeological heritage sites and the dangerous and damaged buildings, with identified and cataloged cracks. In relation to the monitoring of Cultural Heritage and old, unsafe buildings, several different technologies including Light Detection and Ranging (LiDAR) and high-resolution satellite imagery are being successfully used, which involve, however, data processing complexity and the need for specialized expertise. By overcoming the challenges of these traditional methods, this proposed approach holds promise in facilitating comprehensive Cultural Heritage monitoring and management even in smaller and less resource-rich areas. The use of drones for data acquisition and integration into a well-implemented GIS, in fact, could offer a potential solution to monitor Cultural Heritage and assess the condition of existing buildings, while saving time and costs in the process.

A visible-light-induced nickel-catalyzed cross coupling of alkyl carboxylic acids with N-trifluoroethoxyphthalimide is described. Under purple light irradiation, an α-hydroxytrifluoroethyl radical generated from a photoactive electron donor–acceptor complex between Hantzsch ester and N-trifluoroethoxyphthalimide was subsequently engaged in a nickel-catalyzed coupling reaction with in situ-activated alkyl carboxylic acids. This convenient protocol does not require photocatalysts and metal reductants, providing a straightforward and efficient access to trifluoromethyl alkyl acyloins in good yields with broad substrate compatibility. The complex bioactive molecules were also compatible with this catalytic system to afford the corresponding products.
1989 – Annus Mirabilis for The Moldavian SSR
Authors: Musteata Sergiu
Published: September 2023

The study synthesizes the most important events and transformations that
marked Moldovan society in 1989 and its future developments. The study’s
primary aim is to highlight the most important events from 1989 that led the
Moldovan society towards obtaining the sovereignty and independence of
the Republic of Moldova. At the same time, the study also shows the current
knowledge of the 1989 developments to draw new research perspectives.
Thus, in chronological order, the most critical social, cultural, and political
events that have had long-term effects on Moldovan society are reviewed. The
article analyzes the national emancipation movement’s emergence, activity,
and counter-movements to maintain the Soviet regime. The 1989 events in
the Moldavian SSR resulted from Gorbachev’s reforms (glasnost, perestroika)
and the “revolutions” in the socialist states that succeeded in bringing down the
communist regimes. Starting with cultural demands and rights (the language
and alphabet), people had reached economic and political demands (economic
autonomy, sovereignty, independence). The emergence of alternative political
forces to the Communist Party, their official registration, the legalization of
their meetings, and public manifestations led to the consolidation of the critical
mass opposed to the Communist regime. Changing the language legislation,
returning to the Latin alphabet, and condemning the Molotov-Ribbentrop
Pact are just some of the successes of 1989 that impacted the following
years, resulting, eventually, in the Declaration of Sovereignty of 1990 and the
Declaration of Independence of 1991.

La presente investigación realiza una evaluación de la capacidad predictiva de los métodos de estimación del comportamiento mecánico de los suelos lacustres de la bahía de Puno para c|imentaciones superficiales, mediante la aplicación de procedimientos y métodos disponibles. En la bahía de Puno, los suelos lacustres son finos y cohesivos, resultado de partículas transportadas. La creciente demanda de construcción plantea desafíos para entender cómo estos suelos responden a cargas. En proyectos de cimentación, se busca determinar la capacidad de carga para prevenir daños por deformación. Se realizó una revisión de principios de mecánica de suelos para caracterizar estos suelos y se realizaron ensayos de laboratorio y pruebas en modelos a escala real con zapatas en la bahía de Puno. Los resultados nos mostraron la existencia de los suelos lacustres de la bahía de Puno, con contenidos de materia orgánica, que tiene baja resistencia al cortante y son compresibles, produciendo asentamiento perjudiciales para las edificaciones que puedan proyectarse en la zona. Asimismo Los resultados teóricos y las pruebas a escala real mostraron que la determinación predominante de la capacidad de carga se basa en la deformabilidad del suelo. Se encontró que las edificaciones con zapatas cuadradas de 1 metro pueden elevarse 1 piso, mientras que las de 1.50 metros pueden soportar 2 pisos. También se consideran que es posible utilizar métodos basados en resistencia con una reducción en el valor calculado, y se recomienda el método de consolidación unidimensional (edométrico) para calcular la capacidad de carga.

Introducción: la lectura y la escritura son habilidades que contribuyen de manera significativa en todos los procesos formativos del ser humano, sin embargo, en Pruebas de Estado aplicadas en Colombia en los últimos diez años se evidencian que hay estudiantes de Básica Primaria que terminan sin leer y escribir bien. Este artículo está estructurado en una revisión de la literatura para conocer el proceso escritural durante este periodo de formación. Objetivo: identificar la incidencia del proceso de escritura en la composición de textos narrativos a través de investigaciones realizadas en contextos escolares de Básica Primaria mediante una revisión sistemática. Metodología: la revisión bibliográfica se desarrolló en cuatro fases y se seleccionaron investigaciones atendiendo a la guía PRISMA. Lo anterior, en aras de indagar acerca de cada etapa denominadas tiempo para: leer, planear, escribir, revisar, corregir, compartir, reescribir y publicar. Resultados: la escritura está compuesta por varias etapas y los estudiantes que las implementan tienden a producir textos de mejor calidad. Conclusiones: el fortalecimiento de las habilidades escriturales en los estudiantes contribuye a alcanzar un mejor logro académico; por ende, se requiere seguir promoviéndolas en las diversas áreas del conocimiento.
