Authors: Medina Castillo Diana Elizabeth , Hinojosa Ruiz Araceli , Aguilar Medina Diana Alejandra , La Cruz Medina Rodrigo De
Published: March 2024

Inflammatory bowel disease (IBD) is a chronic immune-mediated disorder comprised of Crohn's disease and ulcerative colitis. Ulcerative colitis affects the large intestine, while Crohn's disease can affect any part of the gastrointestinal tract (GIT). IBD is a multisystem condition that predominantly affects the gastrointestinal, musculoskeletal, ocular, and cutaneous systems. The following dermatological manifestations associated with IBDs have been identified: Specific manifestations with the same histological features of the underlying only ocurrs in Crohn Disease (CD); cutaneous disorders associated with IBD aphthous stomatitis, erythema nodosum; reactive mucocutaneous manifestations of IBDs pyoderma gangrenosum, Sweet’s syndrome, bowel-associated dermatosis-arthritis syndrome, aseptic abscess ulcers, pyodermatitis y mucocutaneous conditions secondary to treatment including injection site reactions y eczema and manifestations due to nutritional malabsorption such as stomatitis, glossitis, angular cheilitis hair and nail abnormalities. We believe dermatological examination is essential in all IBD patients, especially in candidates to biologic therapies, in whom drug-induced cutaneous reactions may assume marked clinical relevance, such as psoriasiform eruption. One of the cutaneous manifestations associated with UC is pyoderma gangrenosum (PG), which is an inflammatory neutrophilic dermatosis that clinically presents with well-defined ulcers with an erythematous border and mucopurulent or hemorrhagic exudate.We present the case of a 44-year-old female patient, who presented non-specific chronic ulcerative colitis (UC) with active intestinal symptoms, fever, diarrhea and hematochezia, 20 days later it began with pustules on the head, trunk and extremities, which evolved into an ulcer with a border erythematous and well defined whose clinical and histopathological diagnosis corresponded to pyoderma gangrenosum.

Published: March 2024

Trichoderma is the genus of a cosmopolitan fungus, common in different types of environments or agroecosystems. It has different properties that give it beneficial qualities and functions, which is why it is given different uses, for example, as a biocontrol agent, through induced or direct systemic resistance, as a plant growth stimulant, improving the absorption of water and nutrients and producing phytohormones, as a bioremediator, among others. The objective of this work was to compile knowledge of the characteristics of the genre Trichoderma and the different applications it can have
Atypical presentation of septic hip arthritis with tuberculosis
Authors: Alsaleem Mohammad K , Almohammed Saleh Mohammed , Alarbash Mohammed S
Published: March 2024

Background: Mycobacterium tuberculosis is a rare form of septic arthritis, it remains the major cause of skeletal infection in developing area. Tuberculosis mainly involves the large weight- bearing joints particularly hips, knees and ankles. We describe one of the rarest cases of isolated tuberculosis septic hip without involvement of pulmonary and other extrapulmonary manifestations. Case report: A 15 years old Saudi girl was referred to our hospital with compline of chronic hip pain not response to regular analgesia. The patient becomes unable to bear weight in which she uses a wheelchair. There is no history of trauma. She denied any history of fevers, chills, cough, weight loss, or pulmonary symptoms. There is no history of travel, no history of contact with sick people no history of contact with people who prove to be positive with tuberculosis. She receive all vaccines since birth. Radiological investigation with Acid Fast Bacilli and TB PCR show tuberculosis septic hip. She underwent Arthrotomy and we start Anti TB medication. Conclusion: This case shows the importance of constant care and methodical approach to help ease the early diagnosis of tuberculosis septic arthritis. In all cases of septic arthritis, especially when there is no obvious cause, tuberculosis should be suspected and maintained. Investigations should include a chest radiograph, tuberculin test, microscopy for acid-fast bacilli, and culture for Mycobacterium tuberculosis. And to minimize the delay of diagnosis, a synovial biopsy is suggested to be taken at the initial arthroscopic washout, and request histology.
Socioemotional and Psychological Outcomes of Hypoxic-Ischemic Encephalopathy: A Systematic Review
Authors: Kromm Grace H. , Patankar Hilary , Nagalotimath Shubang , Wong Hilary , Austin Topun
Published: March 2024

BACKGROUND AND OBJECTIVES

Therapeutic hypothermia has reduced the risk of death or major disability following perinatal hypoxic-ischemic encephalopathy (HIE); however, many children who experience perinatal HIE still go on to develop personal and behavioral challenges, which can be difficult for caregivers and a public health burden for society. Our objective with this review is to systematically identify and synthesize studies that evaluate associations between perinatal HIE and socioemotional or psychological outcomes.

METHODS

We screened all search-returned journal articles from Cochrane Library, Embase, Medline, PsycINFO, Scopus, and Web of Science from data inception through February 1, 2023. Keywords related to HIE (eg, neonatal encephalopathy, neonatal brain injury) and outcomes (eg, social*, emotion*, behav* problem, psycholog*, psychiatr*) were searched with a predefined search string. We included all observational human studies reporting socioemotional or psychological sequelae of term HIE. Study data were recorded on standardized sheets, and the Newcastle-Ottawa Scale was adapted to assess study quality.

RESULTS

We included 43 studies documenting 3244 HIE participants and 2132 comparison participants. We found statistically significant associations between HIE and social and emotional, behavioral, and psychological and psychiatric deficits throughout infancy, childhood, and adolescence (19 studies). The authors of the included studies also report nonsignificant findings (11 studies) and outcomes without statistical comparison (25 studies).

CONCLUSIONS

Perinatal HIE may be a risk factor for a range of socioemotional and psychological challenges in the short- and long-term. Routine screening, early intervention, and follow-up support may be particularly beneficial to this population.
Caminhos da crítica

Published: March 2024

No cenário contemporâneo, a potência crítica das ciências sociais tem sido desafiada. De um lado, reconhecemos a democracia como arena agonística (Mouffe), em que o consenso significa sua morte. De outro, a fragmentação das demandas fragiliza as conquistas democráticas, esvaziando a ideia de emancipação. Destacamos os feminismos e os modos como lidam com o conteúdo emancipatório das políticas identitárias. Atentamos para o perigo de se confundir a afirmação das identidades com o termo identitarismos em conivência com essencialismos que podem derivar em extremismos. Buscamos, porém, demonstrar que a crítica, em sentido ecumênico, não produz um antagonismo entre emancipação e identidade, expondo em caráter preliminar a diversidade dos argumentos desde a Teoria Crítica feminista, passando pelo feminismo pós-estruturalista, até os feminismos negros que nunca foram tão eloquentes. Propomos, por fim, a escuta como condição basilar para quem pretende se autodenominar parte do projeto das teóricas críticas.
Experimental fusion (fusión), ritual batá, and gendered interventions
Authors: Meadows Ruthie
Published: March 2024

Cuba constitutes a site of immense importance for the history of jazz (and Latin jazz) in the United States, and attention to the contributions of Cuban women artists contributes to a broader understanding of the gendered histories of global jazz. This article explores women jazz artists in Cuba and its diaspora, excavating how women instrumentalists and vocalists have transformed the landscape of Cuban, Latin, and global jazz through groundbreaking and experimental performances. I attend to how the fusion-centered approaches of Cuban women unearth an emic orientation towards collaborative experimentalism that builds upon specific, local histories of jazz performance on the island. These performances draw upon histories of revolutionary-era musical experimentalism and fusion (fusión) that have emerged since the late 1960s and 1970s in Cuba and which repeatedly tie jazz experimentalism closely—though not categorically—to dance forms (both popular and ritual). Amid Cuba’s intensifying economic crises, I additionally engage how women regularly pursue careers—and, in an overwhelming number of cases, emigration—to Spain, Canada, the continental United States, Puerto Rico, and other international locales, in turn impacting local and translocal jazz scenes.
As Hip(p) as Auer?
Authors: Fuernkranz Magdalena
Published: March 2024

The vibraphonist Vera Auer (1919–1996) and the pianist Jutta Hipp (1925–2003) are known as the ‘first female European jazz musicians’. Both were born in German speaking countries and came in contact with jazz in the 1940s. These instrumentalists had the courage to try out new approaches and develop their own musical ideas early in their careers in jazz scenes shaped by androcentric dynamics. Forms of subversion of gendered assignments are to be seen and heard in Auer’s and Hipp’s performances and influenced a new generation of jazz musicians in recent years. This article discusses the biographies and works of Vera Auer and Jutta Hipp by exploring how these women known as ‘female exception[s]’ built their careers, with a critical eye on power and gender dynamics in German and Austrian jazz scenes. I argue that by subverting various gendered stereotypes such as the trope of the competitive individual jazz soloist, the supportive, caring, egalitarian aesthetic of both Hipp and Auer was coded feminine and therefore ignored in jazz history as a result of patriarchal structures in jazz.

Mathematical modeling of the melt flow in the cone-ring channel of the extruder matrix
Authors: Ospanov Abdymanap , Timurbekova Aigul , Zhalelov Dulat
Published: March 2024

The peculiarity of the work is to develop a mathematical model of the melt flow in the cone-annular channel of the extruder die, which will allow you to choose the optimal geometric shape of the annular channel, as well as the angular rotation speed of the extruder screw. The object of the study is the cone-ring channel of the extruder matrix.
To solve the three-dimensional problem of turbulent and laminar unsteady motion, the FlowVision software package was used, which allows solving partial differential equations using the finite volume method. The correct choice of the geometric shape of the annular gap made it possible to change the molecular structure of the product by creating a maximum pressure value. The optimally selected angular rotation speed of the extruder screw made it possible to carry out deep melting of the product due to the conversion of the mechanical energy of the screw into thermal energy.
In the process of designing the forming of the cone-ring channel, the three volumes of the changing geometry of the stamp were selected, at the borders of the transition of which extreme points were observed. Deviations between the analyzed and experimental values of velocity and pressure were found in the limits of 9–12 % and 17–22 %, respectively.
Based on the analysis of the obtained results of modeling, the optimal geometric shape of the annular gap and the recommended angular rotation speed of the extruder screw were revealed.
The mathematical model proposed formed the basis of the developed design of the six-zone extruder. In the extruder, the geometric characteristics of the screw (variable pitch of the turns) were substantiated and selected, which provide the maximum effect of dissipation, i.e. autogenous mode of operation

The constant increase in the number of threats to the security of critical infrastructure objects, which include socio-cyberphysical systems, leads to a decrease in the quality of security services and the level of security of infrastructure elements. The object of research is the process of building a complex system of protection in socio-cyberphysical systems. The imperfection of the mechanisms for ensuring the security of critical infrastructure objects, which include socio-cyberphysical systems, the technological complexity of identifying new security threats necessitates an urgent need for a radical revision of the current approaches to its provision. So, it becomes clear that the development of a new approach to ensuring the security of information resources in socio-cyberphysical systems is needed. The article proposes a new approach to the methodological foundations of building multi-contour information protection systems with internal and external circuits on each of the platforms of socio-cyberphysical systems. This approach is based on a universal classifier of threats, which takes into account not the technical aspect of threats, but also their integration with social engineering methods, their synergy of hybridity. The sociopolitical influence on the realization of threats is taken into account, and practical mechanisms for providing basic security services based on post-quantum algorithms are also proposed. To provide basic security services in the proposed multi-contour protection system, it is proposed to use post-quantum algorithms – McEliece crypto-code constructions, which provide Perr=10-9–10-12, safe time Tsec=1025–1035 group operations. Within the framework of the proposed approach, the problem of increasing the level of information security has been formalized and further ways of solving it have been determined

Published: March 2024

The object of this study is the dominant forms of investment capital and their convergence according to the stages of development of socio-economic systems. Any evolution has certain stages. The development of socio-economic systems is no exception. All processes and phenomena in the world, including development, occur cyclically and are interconnected with the stages of natural, social, and economic processes. According to the theory of economic cycles, such phenomena as the development of the socio-economic system, its crisis and innovations have a close relationship. Industrial revolutions became a vivid example of changes in the socio-economic development of complex systems. One of the main sources of financing for each stage of the industrial revolution is investment capital, which can be part of industrial, private, financial, banking, or intellectual capital. Depending on the signs of social relations, social system, etc. can take their forms.
Each of the stages of the industrial revolution is preceded by appropriate conditions that are associated with certain historical conditions at a specific moment in time. Considering the dominant forms of investment capital according to the stages of the industrial revolution, the reasons for their change should be noted. The process of convergence of investment capital is considered here.
One of the indicators that characterizes the efficiency of investment capital is its mobility or immobility. A number of macroeconomic factors affect the mobility of investment capital.
Considering the world structure of direct foreign investments, the main directions of their utilization have been indicated. The model of the convergence of the dominant forms of investment capital in the logistics system is presented in accordance with the stage of the industrial revolution and the features that accompany it

The article describes an approach for ranking and selecting field pipelines based on the total cost of ownership of the facility for the purpose of timely repairs and minimization of accidents, as well as its software implementation. The principle of the proposed approach is to apply a technical and economic model of the total cost of ownership of a pipeline, which takes into account the costs of maintaining the pipeline over a long period of time, which include the costs of pipeline maintenance activities, pipeline failures and replacement of pipeline sections. This model allows determining which replacement year corresponds to the minimum accumulated maintenance costs, by varying the year of pipeline replacement from the start of operations to the planning horizon. The model also allows to take into account the impact of operational technological measures on the cost of pipeline ownership and the selection of the optimal year of repair.In order to take into account the level of pipeline accidents in the process of operation on the basis of operational data, a mathematical probabilistic model based on the Weibull distribution was developed. The mathematical model allows to take into account for each pipeline the influence of technical characteristics (diameter, length, wall thickness, material, coating, design features), operating conditions (type of pumped medium, technological mode of pipeline operation) and information on inspection and diagnostics. The accuracy of failure prediction using this model is at least 90 %.The approach to the formation of programs to improve the reliability of field pipelines with regard to optimal repair periods based on the total cost of ownership model is described, taking into account various objectives and constraints, among which the main ones are:- required achievable level of accidents;- acceptable amounts of financing for re-pairs;- permissible physical volumes of repairs along the length.The approach to forming reliability improvement programs described in this article has been implemented in Rosneft's corporate software system RN-SM. The implementation of this software package in production activities is being implemented in 2023–2024.
Reconsideraciones taxonómicas en especies mexicanas de Gonolobus (Apocynaceae-Asclepiadoideae)
Authors: Cervantes-Meza Christopher Ostwaldo , Flores-Olvera María Hilda , Arias Salvador , Alvarado-Cárdenas Leonardo
Published: March 2024

Antecedentes:  En la revisión de Gonolobus para México se observó que G. fuscus, G. luridus y G. tingens carecen de los apéndices estaminales y anillo faucal típicos del género. Los ejemplares observados de estas especies tienen tricomas glandulares tornándose cristalinos y blancos con la edad y la corona ginostegial doble característicos de Polystemma, por lo que se propone su transferencia a este género.
Preguntas: ¿Los datos morfológicos apoyan la transferencia de las especies aquí estudiadas de Gonolobus a Polystemma? ¿Las plantas aquí estudiadas son coespecíficas a alguna de las especies conocidas para Polystemma?
Especies de estudio: G. fuscus, G. luridus y G. tingens.
Sitio y años de estudio: México.
Métodos: Se revisaron los protólogos, las imágenes digitales del material tipo, los ejemplares de herbario de las especies de Gonolobus consideradas y la literatura pertinente. Las especies bajo estudio se compararon morfológicamente con las especies mexicanas conocidas dentro de las Gonolobinae, empleando para ello el concepto cohesivo de especie.
Resultados: Se propone la transferencia a Polystemma de dos de las especies de Gonolobus aquí estudiadas, así como la sinonimización de Gonolobus tingens Decne., Gonolobus suberifer B.L. Rob., Matelea suberifera y M. crenata.
Conclusiones: Con estos ajustes taxonómicos, Polystemma alcanza las 14 especies, resaltando a México como el principal centro de diversidad del género.

Published: March 2024

Background: In Rwanda, interventions have been put in place aimed at reducing stunting among under 5 years children but until now, its prevalence nationwide remains high (33%). A post-program quasi-experimental study was conducted among children between 0 and 24 months in two intervention districts, and two control districts to assess the impact of a nutrition intervention package implemented by a program named Gikuriro. Results: At the end of the Gikuriro program, the prevalence of stunting was 32.2% and 26. 9 % respectively in the intervention group and in the control group. There was no statistical difference between the 2 groups (Chi-square = 0.785, p - value = 0.376) and no observed effect of the nutrition intervention package on stunting (AOR = 1.206, CI at 95% [0.638 - 2.278], p - value = 0.564). Births in the last three years, child’s age, child’s birth size, wealth index, frequency of listening to radio, and months of breastfeeding were associated with stunting in the intervention group whereas in the control group, stunting was associated with receiving multiple micronutrients in last 7 days and beating justified if wife goes without telling husband. Conclusion: A second study is advised before deciding whether to scale up nutrition programs aimed at reducing stunting since only end program evaluation was considered and the stunting trend between baseline and end line has not been evaluated additionally there were some particular initiatives put in place aiming at reducing stunting in the control group.

Indonesia as one of the member countries with the largest GDP in the world. has its own challenges to be able to maintain and even increase GDP. In fulfilling this, the government is still trying to increase the provision of infrastructure in Indonesia to support construction developments in industrial areas and work together with the private sector (investors, contractors and operators) to realize the provision of these areas. The process of developing industrial estates this requires tools to analyze risks. In reality it is very difficult to control the emergence of risks that cannot be resolved or overcome, starting from identifying risks to finding ways to reduce their impact on achieving project objectives regarding the level of risk involved. Risk factor analysis is seen from the magnitude of the impact (impact) and the probability (probability) of the risk event. Based on previous research, a summary is made by separating the risk into 2 stages of risk. The first is the risk during pre-construction and the second is during the construction stage. The risk weights and risk categories are obtained from the results of risk identification, the risks identified in development projects in the industrial area are 28 risks and 8 types of risk sources. It is the risks that have quite a large value that are the most dominant risks that occur in development projects in industrial estates, based on the results of an analysis of the frequency of occurrence of risks and based on the impact of the risks that occur. Risk of tender process error, contract document error, standardization differences, community rejection, risk of weather conditions.

Migrant Agricultural Workers’ Experiences of Support in Three Migrant‐Intensive Communities in Canada
Authors: George Glynis , Lozanski Kristin , Mayell Stephanie , Caxaj Susana
Published: March 2024

Canada has intensified its reliance on temporary foreign workers, including migrant agricultural workers (MAWs) who have contributed to its agriculture sector, rural economies, and food security for decades. These workers live and work in rural communities across Canada for up to two years. Thousands of MAWs engage in recurring cyclical migration, often returning to the same rural communities in Canada for decades, while others are undocumented. Yet MAWs do not have access to the supports and services provided for immigrant newcomers and pathways for permanent residence. The exclusion of these workers from such entitlements, including labour mobility, reinforces their precarity, inhibits their sense of belonging, and reflects the stratification built into Canada’s migration regime. This article draws on interviews with 98 MAWs in three migrant‐intensive regions in southwestern Ontario to examine how workers construct and describe support in relation to co‐workers, employers, residents, and community organizations. Drawing on conceptualizations of support as an important vehicle for social connection and inclusion that comprises social and citizenship belonging, we document how the strategies MAWs employ to forge connections are enabled or undermined by Canada’s Temporary Foreign Worker Program, community dynamics, and the broader forces of racialization, gender, and exclusion. This article contributes to the limited scholarship on the support landscape for MAWs, whose experiences foreground the contested nature of belonging and inclusion among migrant populations across smaller cities and rural areas.
Modular Design of Teaching Cases: Reducing Workload While Maximizing Reusability

Many software development courses rely heavily on a project-based learning component to provide hands-on experience with the majority of the course objectives. Courses such as systems analysis and design, database design, software engineering, and capstone software development courses often incorporate some form of case-based project that is much more extensive and integrated than are focused exercises over individual topics. To be truly educational, case studies can require a significant investment in time and effort on the part of the instructor, an investment that seldom carries over into future academic sessions. This paper presents a modular case study development concept for better managing the development of case studies and achieving project extensibility through reusable case study modules, while at the same time helping to reduce instructor workload and solution reuse by students.

Encyclopedic literature and dictionaries devoted to geological sciences were overviewed in the article. The authors emphasize the lack of basic Ukrainian geological encyclopedia and provide arguments for the necessity of its appearance. They substantiate the importance of dictionaries representing specific subject lexicon, in particular geological terminology: "Dictionary of Geological Terminology" (1923), "Russian-Ukrainian Geological Dictionary" (1959), "Russian-Ukrainian Dictionary of Geological Terms" (1993), "Russian-Ukrainian Geological dictionary" (2011), "Ukrainian-French-English Dictionary of Geology, Geophysics, Well Drilling, and Oil, & Gas industry" (2011), "Russian-Ukrainian Geological Dictionary" (2016), "Geological Dictionary: Open Educational and Scientific Web Resource" (2017), "Russian-Ukrainian Geological Dictionary" (2018), "Ukrainian-Russian-English Dictionary of Geological Terms" (2020), and other mineralogical, geodetic, mining, petrographic dictionaries. The results show that Ukrainian encyclopedic and lexicographic literature does not provide knowledge of all geological sciences despite a fairly large number of encyclopedias and dictionaries (in total, over 40 sources were found), as there are dictionaries and encyclopedias encompassing only some particular geological fields. The authors also reflect on the issue of the distribution of subject encyclopedias and dictionaries in educational sphere today, when Wikipedia is considered to be the most popular online reference work in the world. The authors conclude that it is necessary to build a modern geological encyclopedia as a unified Ukrainian language source of reliable reference knowledge on geology.

The use of the palaeomagnetic method in stratigraphy is based on the evidence of geomagnetic field polarity changes (inversions) as well as the existence of excursions, short-term (up to 10 ka) deviations of the virtual geomagnetic pole from its usual position, which occurred sometimes only on a regional scale. The excursions as magnetostratigraphic benchmarks are a powerful tool in the correlation of the Quaternary deposits. In 19601990 particular attention was paid to them as important correlation markers across the regional chronostratigraphic scales of the Quaternary. However, the quantity of the Brunhes chron excursions, their stratigraphic position and ages have been debatable. In recent years, many papers have been published clarifying the nature, age, and duration of excursions in various deposits. In the first part of the article a detailed overview of the Brunhes chron excursions is provided, considering the current state of the issue of determining their suitability.

According to data obtained by NASA's InSight mission, Mars appears to be a seismically active planet. In this paper, we focus on two events – S0235b and S1222a, the second of which (May 4, 2022, Mw~4.7) is the strongest of all recorded by the broadband seismic station ELYSE, the only one on Mars. Epicentral distance of S1222a was 37.2°. We determine the focal mechanisms of events using the method based on the model of a point source in an elastic horizontally layered medium. Seismic moment tensor is determined by inversion of high-frequency seismograms calculated by the matrix method for direct waves. The process involves convertion into displacements in the time domain after integration over frequency and wavenumber. The use of only direct P- and S-waves, which are less sensitive to propagation effects than reflected and converted ones, significantly improves accuracy and reliability of the proposed method. For the event S1222a, the match of the synthetic forms of direct waves to the observed ones is demonstrated. A comparative analysis of the focal mechanisms obtained for the S0235b event by inversion of only direct waves and by full direct inversion is also presented.

Authors: Ande Janaki Rama Phanendra Kumar
Published: March 2024

This project aims to understand better how to incorporate nonlinear soil-structure interaction (SSI) effects into high-rise building performance-based seismic design approaches. The primary goals are to determine how important it is to include nonlinear SSI effects, create integration methods for them, and analyze how they affect seismic resilience. In terms of methodology, the study uses case studies and an analysis of current literature to show real-world applicability. Important discoveries highlight how critical nonlinear SSI analysis is for precisely forecasting structural reactions, locating weaknesses, and creating focused mitigation strategies. The policy implications emphasize the necessity of modern building regulations, research and development expenditures, and advancements in site characterization methods to facilitate the implementation of performance-based design methodologies. To improve the resilience and safety of high-rise buildings in earthquake-prone areas, this study's findings highlight the significance of considering nonlinear SSI effects during seismic design procedures.

Anthropometric, mechanical and performance differences have been observed in rowing between rowers from the same club competing in different categories. Maximal aerobic power has been defined as one of the best predictors of rowing performance. The aim was to observe differences between male and female rowers in anthropometric, physiological and aerobic power data. Weight (P), height (T), fat percentage (G), sum of seven folds (S7) and absolute and relative watts (W) (W/kg) of 55 subjects were assessed. Of the 55 subjects, 38 were male (26.95 ±7.0 years) and 17 were female (24.82 ±6.8 years). Cohen’s d was used to calculate the effect size as standardised mean difference. In the results, sample means were obtained for the variables analysed in the different sexes (F: females and M: males). For F: [P: 77.25 (9.41) - T: 1.80 (0.07) - G: 12.77 (3.04) - S7: 72.23 (28.20) - W: 273.6 (52.88) - W/kg: 3.57 (0.67)] and for M: [P: 61.79 (6.85 - T: 1.67 (0.07) - G: 14.44 (2.47)- S7: 103.83 (28.64) - W: 171.35 (29.19) - W/kg: 2.78 (0.43)]. Finally, the results were as follows: P: 1.77 - T: 1.87 - G: 0.57 - S7: 1.11 - W: 2.17 - W/kg: 1.28. Showing significant differences and a large effect size between both sexes in all the variables analysed, except for the fat percentage variable.

Published: March 2024

In the era of information technology, hospitals, medical centers, doctors and health specialists share millions of images. Securing these images is essential to maintaining patients’ privacy. Several cryptographic algorithms are implemented to meet the increasing demands of transmission systems. As a contribution to securing these data, we propose a novel robust and efficient algorithm. We randomly generate numbers from a six-dimensional hyperchaotic system and Arnold’s cat map to confuse the original images. The confused images are then diffused using a k-Fibonacci matrix. The performance of the proposed algorithm was evaluated using several parameters tested on a set of reference images of different sizes and modalities. The obtained results are conclusive and the performances are excellent, sometimes exceeding those found by other recent algorithms proposed in the literature.
