Method “Monte Carlo” in healthcare

In public health, simulation modeling stands as an invaluable asset, enabling the evaluation of new systems without their physical implementation, experimentation with existing systems without operational adjustments, and testing system limits without real-world repercussions. In simulation modeling, the Monte Carlo method emerges as a powerful yet underutilized tool. Although the Monte Carlo method has not yet gained widespread prominence in healthcare, its technological capabilities hold promise for substantial cost reduction and risk mitigation. In this review article, we aimed to explore the transformative potential of the Monte Carlo method in healthcare contexts. We underscore the significance of experiential insights derived from simulated experimentation, especially in resource-constrained scenarios where time, financial constraints, and limited resources necessitate innovative and efficient approaches. As public health faces increasing challenges, incorporating the Monte Carlo method presents an opportunity for enhanced system construction, analysis, and evaluation.

Asymmetric Optical Scanning Holography Encryption with Elgamal Algorithm

This paper proposes an asymmetric scanning holography cryptosystem based on the Elgamal algorithm. The method encodes images with sine and cosine holograms. Subsequently, each hologram is divided into a signed bit matrix and an unsigned hologram matrix, both encrypted using the sender’s private key and the receiver’s public key. The resulting ciphertext matrices are then transmitted to the receiver. Upon receipt, the receiver decrypts the ciphertext matrices using their private key and the sender’s public key. We employ an asymmetric single-image encryption method for key management and dispatch for securing imaging and transmission. Furthermore, we conducted a sensitivity analysis of the encryption system. The image encryption metrics, including histograms of holograms, adjacent pixel correlation, image correlation, the peak signal-to-noise ratio, and the structural similarity index, were also examined. The results demonstrate the security and stability of the proposed method.

Orthodontic Survey: Among the surveyed orthodontists, 71% treated cleft/craniofacial patients, 37% accepted Medicaid, and 55% provided pro-bono care. Poor reimbursement was identified as the most common barrier (58%). Caregiver Survey: Most patients were insured by Medicaid (67%), with 55% incurring out-of-pocket expenses. PHIS Database: The average age of ABG was 10.3 years (SD = 3.2). Government funding was associated with a 6.0-month delay in ABG (p = 0.047) and residing in non-Medicaid expanded states was linked to a 6.0-month delay (p = 0.023). Post-Medicaid expansion status was also associated with a delay (p = 0.004). Access to oral care is difficult for patients with OFC. Despite both federal and state mandates, many financial and non-financial barriers still exist in accessing orthodontic care and a majority of patients experience significant out-of-pocket expenses despite statutorily mandated insurance coverage.

Modeling energy storage in long-term capacity expansion energy planning: an analysis of the Italian system

This paper presents a framework to represent short-term operational phenomena associated with renewables capacity factors and final service demand distributions in a capacity-expansion and integrated energy system optimization model. The aim is to study the potential role of energy storage technologies coupled with renewable energy sources aiding the decarbonization of the overall energy system. The proposed methodology is implemented in an energy system optimization model named Tools for Energy Model Optimization and Analysis (TEMOA) and then tested in a case study focused on the Italian energy system. We examine a collection of scenarios that includes reference time scale scenarios, time scale sensitivity scenarios, and technology alternative scenarios. This paper's findings indicate that energy storage is crucial for fully decarbonizing the Italian power sector by 2050 in the absence of a low-carbon baseload. Additionally, it suggests that approximately 10 % of Italy's electricity generation in 2050 should be routed through short-term energy storage devices.

SYSTEMATICITY OF THE FORMATION OF POTENTIAL WORDS AS AN EXPRESSION OF THE TRANSPARENCY OF THE LEXICAL SYSTEM OF THE RUSSIAN LANGUAGE

The work is devoted to the study of potential nouns and adjectives. The purpose of the study is to identify the place of potential words in the word-formation system of the Russian language. The following methods of linguistic analysis were used in the work: a synchronous-descriptive method, including observation, comparison, juxtaposition, generalization, interpretation of linguistic data, and system analysis method. The material for the description was mainly the works of E. Yevtushenko. As a result of the analysis, it was revealed that potential words are a product of speech, not language. But they represent part of the general word formation and stand out in it. Potential words are laid down by the word-formation system of the language itself, created based on productive models of the Russian word-formation system. They can fill in the empty cells of word-formation paradigms using productive word-formation models. The study of trends in the development of modern Russian word formation has an undoubted theoretical significance for the development of the science of word formation, which makes it possible to study the mechanism of the emergence of new words. Also, it makes it possible to practically apply the findings in university teaching of word formation, lexicology of the Russian language, in the practice of compiling dictionaries, etc. KEYWORDS: derivation, methods of derivation, morphemes, derived word, potential word (potentialism).

The Anthropological Factor of the New Generation of War Technologies

Introduction. The article studies the humanitarian technologies of hybrid wars (wars of the new generation). Physical violence in the conditions of their activation is replaced by nonphysical violence using coercion, inducement and manipulation. Therefore, understanding not only the phenomenon of hybrid wars itself, but also the humanitarian technologies actively used in them, is of particular relevance. The purpose of the study is to reveal humanitarian technologies as the leading force of the new generation of wars.Methodology and sources. Systematization, categorization, interpretation of concepts and system analysis were used as the main methods in the study. The work is based on the research of I.Y. Alekseeva, V.G. Kokoulin, B.V. Markov and some other authors whose works devoted to the humanitarian technologies of the new generation of war.Results and discussion. Hybrid warfare technologies are of a mixed nature, however, in recent years, the attraction of actors of global confrontation to the humanitarian technologies of modern warfare has become obvious. At the first stage of the research, the phenomenon of hybrid warfare was considered, its definition was given, its essence and potential were revealed. Hybrid warfare is an implemented strategy of controlled chaos. At the second stage, there were considered various hybrid warfare technologies, the most promising of which are humanitarian technologies. The definition of such technologies was given, their subjects and objects were disclosed, as well as their purpose. The third stage of the study is devoted to the consideration of specific examples of humanitarian technologies, including the creation of deepfakes, the spread of disinformation and a number of others.Conclusion. In the last few years, the humanitarian technologies of a new generation of war have found their niche in the face of confrontation between historical opponents, while the political goals of such confrontation have remained the same. However, the object of influence has changed, it has become a person.

Cardiovascular equity and health center funding: Associations of unmet hypertension and diabetes need by race/ethnicity and federal grants at federally qualified health centers, 2014-2019.

Racial and ethnic disparities in chronic disease are a major public health priority. To determine if the amount of federal grant funding to federally-qualified health centers (FQHCs) was associated with baseline overall prevalence of uncontrolled hypertension and uncontrolled diabetes, as well as prevalence by racial and ethnic subgroup. Cross-sectional multivariate regression analysis of Uniform Data System 2014-2019, which includes clinic-level data from each FQHC regarding demographics, chronic disease control by race and ethnicity, and grant funding. Our main exposure were the average values of the prevalence of uncontrolled hypertension and uncontrolled diabetes among the overall population and by racial and ethnic group from 2014-2016. Average federal grant funding per patient from 2017-2019, as measured by annual health center funding from the Bureau of Primary Health Care (BPHC) and overall federal grant funding. We analyzed 1,205 FQHCs from 2014-2019; the average BPHC grant per patient across all FQHCs in 2019 was $168 while the average total federal grant was $184 per patient. Increasing shares of total patients with uncontrolled hypertension or uncontrolled diabetes were not associated with increased total federal grant funding in either unadjusted or adjusted analysis. Increased shares of patients who are American Indian or Alaskan Native (AI-AN) with uncontrolled hypertension and diabetes were associated with increasing total federal grant funding in both unadjusted and adjusted analysis (adjusted beta hypertension $168.3, p <0.001; adjusted beta diabetes 59.44, p = 0.02). However, cardiovascular clinical need among other racial and ethnic groups was not significantly associated with grant funding. FQHCs with higher overall rates of uncontrolled hypertension or diabetes do not receive more federal funds, and there is no significant association between federal funding levels and rates of uncontrolled blood pressure or diabetes within most racial and ethnic groups, with the exception of AI-AN populations. To narrow inequities in cardiovascular disease, HRSA should consider more explicitly targeting federal grants to clinics with higher levels of clinical need.

A dynamic evaluation of an underground transportation system using image processing and centrality index computation

ABSTRACT The study of transportation networks covers a wide range of topics related to managing services and maintaining structures. In order to represent the topological structure of such a network, we associated a graph to a network. Then some different properties or attributes of the network can be managed as weights to be applied to the graph itself. In addition, different centrality indices can be computed in order to identify nodes or edges that are more important or more exposed to capacity changes (such as, for example, disruptive events). The purpose of this research is to provide a methodology for dynamically evaluating the significance of stations in a transportation network. This is accomplished through two distinct phases of activity. Firstly, we propose a dynamic analysis of the underground transportation system of the city of Milan, Italy. This transportation system is the mobility backbone of the city and counts four lines with 110 links and 107 stations, including 21 junctions (the transfer stations that connect the lines). Two data sets about passenger flows (both entering and leaving stations) are used to calculate the flows on links with a resolution of 1 min. The data sets refer to a week in 2018, without the changes in demand due to the pandemic scenario. Data are processed through an ad hoc written assignment procedure. Secondly, a centrality index is calculated by using passenger flows (entering, exiting, and on-segments) as weights of the underground graph. After maps reporting the outcomes of those calculations are drawn, an image comparison is carried out by using image processing tools and different aggregation intervals, in order to investigate how the importance or exposure of each station changes over time. The findings demonstrate that over time, indices vary by station, with junction stations naturally having the highest values. By increasing the observation interval from 1 min up to 30 min, index changes become progressively smoother, like an application of a low pass filter, suggesting that for certain applications (e.g. those concerning security), aggregating data could lead to misleading conclusions.

Using Carbon Dioxide for Subsea Long-Duration Energy Storage

This paper investigates the operating benefits and limitations of utilizing carbon dioxide in hydro-pneumatic energy storage systems, a form of compressed gas energy storage technology, when the systems are deployed offshore. Allowing the carbon dioxide to transition into a two-phase fluid will improve the storage density for long-duration energy storage. A preliminary comparative study between an air-based and a carbon dioxide-based subsea hydro-pneumatic energy storage system is first presented. The analysis is based on thermodynamic calculations assuming ideal isothermal conditions to quantify the potential augmentation in energy storage capacity for a given volume of pressure containment when operating with carbon dioxide in lieu of air. This is followed by a transient thermal analysis of the carbon dioxide-based hydro-pneumatic energy storage system, taking into account the real scenario of a finite thermal resistance for heat exchange between the gas and the surrounding seawater. Results from numerical modelling revealed that the energy storage capacity of a carbon dioxide-based subsea hydro-pneumatic energy storage system operating under ideal isothermal conditions can be theoretically increased by a factor of 2.17 compared to an identical air-based solution. The numerical modelling revealed that, under real conditions under which transient effects resulting from a finite thermal resistance are accounted for, the achievable factor is lower, depending on the charging and discharging time, the initial temperature, and whether a polyethene liner for corrosion prevention is considered or not.

In the legal literature, the model of a progressive system of execution and serving of imprisonment is increasingly associated with a change in the legal status of a convicted person serving a criminal sentence, depending on the positive or negative behavior of the convicted person towards improvement or deterioration. Such judgments, in the author’s opinion, are not supported by the study of the progressive system from the position of the general definition of the system as a set of elements in mutual relations and connections forming a certain integrity, unity, as well as its understanding in the aspect of system analysis. To create a systematic understanding of the object of a progressive system with its systemic and legal characteristics, it is necessary to study it from the standpoint of system analysis, which is a means of improving and developing the current state of the progressive system as a whole (increasing its effectiveness). In the domestic legal literature, the systemic status of the object of the progressive system is not studied from the indicated positions. To show more clearly the features of the inseparability of system analysis from the object of the system (a person in custody; a person sentenced to imprisonment; For the first time, an attempt was made to create a systemic legal model of the systemic status of an object of a progressive system. In addition, the definition of the concept of the systemic status of an object of a progressive system is constructed, as well as its author’s concept is proposed, the structural elements of the systemic status of an object of a progressive system proposed for discussion are analyzed. The judgments given in the study have not yet found their completeness and are debatable, but their comprehensive study will allow us to take a different look at the reflection of the current concept of a progressive system in the norms of domestic legislation.

Case Report: Soft tissue infection with Burkholderia thailandensis capsular variant: case report from the Lao PDR

Background Burkholderia thailandensis is an environmental bacteria closely related to Burkholderia pseudomallei that rarely causes infection in humans. Some environmental isolates have shown to express a capsular polysaccharide known as B. thailandensis capsular variant (BTCV), but human infection has not previously been reported. Although B. thailandednisis has been identified in environmental samples in Laos before, there have not been any human cases reported. Case A 44-year-old man presented to a district hospital in Laos with a short history of fever and pain in his left foot. Physical examination identified a deep soft-tissue abscess in his left foot and an elevated white blood count. A deep pus sample was taken and melioidosis was suspected from preliminary laboratory tests. The patient was initially started on cloxacillin, ceftriaxone and metronidazole, and was then changed to ceftazidime treatment following local melioidosis treatment guidelines. Laboratory methods A deep pus sample was sent to Mahosot Hospital microbiology laboratory where a mixed infection was identified including Burkholderia sp. Conventional identification tests and API 20NE were inconclusive, and the B. pseudomallei-specific latex agglutination was positive. The isolate then underwent a Burkholderia species specific PCR which identified the isolate as B. thailandensis. The isolate was sent for sequencing on the Illumina NovaSeq 6000 system and multi-locus sequence typing analysis identified the isolate had the same sequence type (ST696) as B. thailandensis E555, a strain which expresses a B. pseudomallei-like capsular polysaccharide. Conclusion This is the first report of human infection with B. thailandensis in Laos, and the first report of any human infection with the B. thailandensis capsular variant. Due to the potential for laboratory tests to incorrectly identify this bacteria, staff in endemic areas for B. thailandensis and B. pseudomallei should be aware and ensure that appropriate confirmatory methods are used to differentiate between the species.

Design and Technological Aspects of Integrating Multi-Blade Machining and Surface Hardening on a Single Machine Base

Modern mechanical engineering faces high competition in global markets, which requires manufacturers of process equipment to significantly reduce production costs while ensuring high product quality and maximum productivity. Metalworking occupies a significant part of industrial production and consumes a significant share of the world’s energy and natural resources. Improving the technology of manufacturing parts with an emphasis on more efficient use of metalworking machines is necessary to maintain the competitiveness of the domestic machine tool industry. Hybrid metalworking systems based on the principles of multi-purpose integration eliminate the disadvantages of monotechnologies and increase efficiency by reducing time losses and intermediate operations. The purpose of this work is to develop and implement a hybrid machine tool system and an appropriate combined technology for manufacturing machine parts. Theory and methods. Studies of the possible structural composition and layout of hybrid equipment at integration of mechanical and surface-thermal processes were carried out, taking into account the basic provisions of structural synthesis and componentization of metalworking systems. Theoretical studies were carried out using the basic provisions of system analysis, geometric theory of surface formation, design of metalworking machines, methods of finite elements, and mathematical and computer modeling. The mathematical modeling of thermal fields and structural-phase transformations during HEH HFC was carried out in ANSYS (version 19.1) and SYSWELD (version 2010) software packages using numerical methods of solving differential equations of unsteady heat conduction (Fourier equation), carbon diffusion (2nd Fick’s law) and elastic–plastic behavior of the material. The verification of the modeling results was carried out using in situ experiments employing the following: optical and scanning microscopy; and mechanical and X-ray methods of residual stress determination. Formtracer SV-C4500 profilograph profilometer was used in the study for simultaneous measurement of shape deviations and surface roughness. Surface topography was assessed using a Walter UHL VMM 150 V instrumental microscope. The microhardness of the hardened surface layer of the parts was evaluated on a Wolpert Group 402MVD. Results and discussion. The original methodology of structural and kinematic analysis for pre-design studies of hybrid metalworking equipment is presented. Methodological recommendations for the modernization of multi-purpose metal-cutting machine tool are developed, the implementation of which will make it possible to implement high-energy heating with high-frequency currents (HEH HFC) on a standard machine tool system and provide the formation of knowledge-intensive technological equipment with extended functionality. The innovative moment of this work is the development of hybrid metalworking equipment with numerical control and writing a unique postprocessor to it, which allows to realize all functional possibilities of this machine system and the technology of combined processing as a whole. Special tooling and tools providing all the necessary requirements for the process of surface hardening of HEH HFC were designed and manufactured. The conducted complex of works and approbation of the technology of integrated processing in real conditions in comparison with traditional methods of construction of technological process of parts manufacturing allowed to obtain the following results: increase in the productivity of processing by 1.9 times; exclusion of possibility of scrap occurrence at finishing grinding; reduction in auxiliary and preparatory-tasking time; and reduction in inter-operational parts backlogs.
