A COMPARISON OF MULTIPLICATIVE AND ADDITIVE HAZARD MODELS USING THE HAZARD AND SURVIVAL RATIO
Authors: Danardono Danardono , Gunardi Gunardi
Published: January 2025

The Cox multiplicative hazards regression and Aalen additive hazards regression models are widely used for survival data analysis. While the Cox model emphasizes hazard ratios or relative risks, the Aalen model focuses on relative survival or excess risks. This study compares the performance of these models through simulations of biomedical survival data. Results reveal no clear dominance of one model over the other, suggesting that both models should be employed to have a more thorough survival analysis.
Drottning Sofia Magdalenas läsning. Böcker, konversation, och socialt spel vid det Gustavianska hovet
Authors: Berndtsson Tim
Published: January 2025

This article examines the role of conversation in aristocratic reading culture in late eighteenth-century Sweden. Taking Queen Sophia Magdalena (1743–1813) as example, the study examines the criticism raised by other members of the royal family against her supposed disinterest in literature. By contextualizing what “reading” meant at the Swedish royal court, and by investigating the catalogue of Sophie Magdalena’s private library, I argue that being judged as “well-read” and “cultivated” was not necessarily as much connected to the time spent reading or the number of volumes owned, as the capacity to converse about literature in a way deemed proper.
Begegnungen mit dem Tod in der norwegischen Gegenwartsdramatik
Authors: Stark Kristina , Krutzinna Leonie , Rottler Kerstin
Published: January 2025

Representations of death have a long tradition in literature. The three plays, Tilbakekomstene by Fredrik Brattberg, Jeg forsvinner by Arne Lygre, and Ikkje direkte råka by Maria Tryti Vennerød, stand as examples of the contemporary Norwegian drama and theatre – with Brattberg’s and Lygre’s literary minimalism and Vennerød’s performative approach. Death on stage is explored from different perspectives – on a personal level, in an anthropological way of looking at society and from a political view. In Tilbakekomstene, nameless parents exposed to their son’s death are stuck in a cycle of disappearing and reappearing as well as reality and illusion – reminiscent of the musical elements of rhythm and repetition. In Jeg forsvinner, the protagonist’s escape is contrasted with those who remain, but finally all the characters realize that they are trapped without hope. Their fear of destruction is portrayed in scenes taking place simultaneously. Ikkje direkte råka. Dagbok 16/4–22/6 2012, referring to the terror attacks in 2011 and the trial at court, addresses the contrast between the individual’s fear of death and the values of a collective We within Norwegian society with all its complexity and ambiguity. More a performance than a play, it consists of blog entries and passages in prose and verse. All three plays lack a straightforward plot, they present simultaneous scenes, static figures, minimal language and a timeless and placeless setting. The rejection of empathy and identification can be seen as a modern concept of memento mori in the 21st century.
Characterizing Homeland Security Risk: A Principal Component Analysis of 10 Hazards
Authors: Lundberg Russell
Published: January 2025

This research reduces the number of attributes to describe the varied risks in the homeland security domain using Principal Component Analysis (PCA). Reducing the dimensions of homeland security risks to a smaller, more manageable set of characteristics can enhance policy-making processes, especially given the broad spectrum of consequence and non-consequence attributes and the varying frequencies of such events. PCA was used to reduce the larger set of risk attributes to five – representing health, economic, societal, dread and the unknown – or two – representing consequence and perceptual characteristics. While the five-component approach describes the data more completely, the two-component approach also explains a large proportion of the variance of the dataset but does so with a lower cognitive load. Either approach can provide composite variables that describe the homeland security risks in a more efficient fashion without losing excessive information on the risks.

Published: January 2025

Objectives

To develop a clinical model for predicting the occurrence of Central Precocious Puberty based on the breast development outcomes in chinese girls.

Methods

This is a retrospective study, which included a total of 1,001 girls aged 6–9 years old who visited the outpatient clinic of Beijing Children’s Hospital from January 2017 to October 2022 for “breast development”. Participants were categorized into pubertal development (PD) cohort and simple premature breast development (PT) according to the criteria, and information was collected and tested for relevant indicators. After dealing with missing data, logistic regression, LASSO regression and random forest were used to screen the variables, and support vector machine models were built with SMOTE oversampling and ten-fold cross-validation to assess the effectiveness of the models in the training and validation sets.

Results

1,001 girls were included in the analysis, of whom 369 (36.9 %) were diagnosed with PD and 632 (63.1 %) with PT. Body mass index (BMI), bone age (BA), luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), uterine diameter, and ovary volume were identified as the final predictor variables by three variable screening methods. The AUC of the constructed disease diagnostic model was 0.9457 in the developmental cohort and 0.8357 in the external validation group, and sensitivity analyses revealed that the performance of the constructed models with different variable selection strategies was similar.

Conclusions

A disease diagnostic model was developed that may help predict a girl’s risk of diagnosing central precocious puberty.

Authors: Shi Chenglong , Ma Yanhong , Wang Yongfeng , Chen Xueqi , Hong Jie
Published: January 2025

To achieve a highly efficient conical shaft design in aviation gas turbine engine’s rotor system, firstly, a 4-DOF cantilevered rotor model is established to investigate the effects of the lateral, angular and cross stiffness of the rotor on the resonance speed of the pitching mode. The results show that increasing the lateral and angular stiffness, while reducing the cross stiffness, is beneficial for raising the critical speed of the pitching mode. Subsequently, using finite element method, the relationships between the cone angle, dimensionless radius, dimensionless span, and the stiffnesses of conical shaft are calculated. It is observed that, under various structural design constraints, the conical shaft with maximum stiffness exhibits different cone angles. Finally, experiments are conducted with flexible rotors featuring conical shafts of varying cone angles to validate the research conclusions. This paper provides guidance for the configuration design of rotors in aero-engine.

Published: January 2025

Plenty aspect of human life across various regions, also Indonesia, utilizes electronic systems for a multitude of activities, and involving digital platforms. The concept of Digital Platform Powerplay is linked to the digital market and personal data protection. In Indonesia, the regulatory framework governing digital markets and personal data primarily relies on Law No. 11/2008 concerning Electronic Information and Transactions, which has undergone two amendments: Law No. 19/2016 amending Law No. 11/2008, and Law No. 1/2024 amending Law No. 11/2008 for the second time and Law No. 27/2022 concerning Personal Data Protection. As a implementation regulation Government Regulation No. 80/2019 concerning Electronic Commerce and Government Regulation No. 71/2019 concerning the Implementation of Electronic Systems and Transactions further elaborate on these regulations. These legal provisions are intended to provide legal certainty for users. It is essential to review all regulations related to electronic systems and digital platforms by comparing them with the regulatory frameworks in the European Union. The study addresses two primary issues: 1) the legal regulation of digital markets from the perspective of Indonesian positive law, and 2) the legal regulation of digital markets from the perspective of European Union law. This research employs normative legal research methodologies, utilizing both statutory and comparative approaches. The findings of this study suggest that Indonesia should consider adopting the European Union's Digital Markets Act and Personal Data Protection regulations by amending Law No. 11/2008 concerning Electronic Information and Transactions and its amendments, with particular emphasis on aspects related to Digital Platform Powerplay.

Published: January 2025

Esophageal foreign body is common in pediatric age group but is rare in neonatal period. A 5-days old newborn presented to us with provisional diagnosis of Esophageal atresia (EA) with or without Tracheo-esophageal fistula (TEF). Child had drooling of saliva and inability to feed. Surprisingly X-ray showed radiopaque shadow in esophagus. Esophagoscopy revealed an impacted stone with a large ulcer. Stone was mobilized by endoscopy but could not be retrieved above cricopharynx due to proximal esophageal oedema. Stone was pushed into stomach and was retrieved by gastrotomy. Literature search from 1955-2022(67 years), identified thirty-nine neonates with wide variety of esophageal FB. Details are discussed with different modalities used for removal of FB and their outcome.

Authors:   Institute for Problems of Cryobiology and Cryomedicine of the National Academy of Sciences of Ukraine, Kharkiv, Lomako Viktoria , Shylo Oleksandr ,   Institute for Problems of Cryobiology and Cryomedicine of the National Academy of Sciences of Ukraine, Kharkiv
Published: January 2025

It was speculated that the whole-body cryostimulation (WBC) would adjust the negative effect of desynchronosis on the body. One-time WBC was performed in a cryochamber at –120°C a day before the desynchronosis simulation, which was initiated by shifting the light regimen. The WBC effi cacy was determined by leukocyte parameters of the blood of 6- and 18-monthold rats. Types of leukocytes were counted in blood smears. Integral leukocyte indices were used to assess the immune system state. Preventive application of WBC restored the number of lymphocytes and eosinophils and increased the number of monocytes in rats of both age groups, as well as the total leukocytes count in young animals. In animals of both age groups, young forms of neutrophils predominated, immunoreactivity decreased, the effector link of immunity and the macrophage system were activated. Delayed-type hypersensitivity processes in young rats as well as immediate-type hypersensitivity processes in aged rats were activated, and the reactive response of neutrophils decreased/increased according to the age of the animals.

Published: January 2025

Polyphenol solvent extraction from vegetable matrices has gained significant importance in various sectors, including food, pharmaceuticals, and agro-industries. This research focuses on the experimental design of Batch extraction procedures for obtaining polyphenols from dried and milled chicory roots. Air-forced and vacuum-drying techniques were employed to dry fresh chicory roots. The research examined the impact of operational variables on obtaining extracts from dried chicory roots. We developed a comprehensive mathematical model using diffusion transfer principles, taking into account various operational factors. We integrated the model into the optimization tool General Algebraic Modeling System (GAMS) and subsequently validated it through experimentation. The results demonstrated strong agreement between the theoretical and experimental data, with satisfactory values for both the root mean square error and correlation coefficients. The optimal extraction conditions that yielded maximum outputs were 50ºC temperature, 1.10 m s-1 agitation speed, 50% ethanol concentration, and 20 ml solvent per gram of flour. Moreover, we observed higher diffusivity coefficients for polyphenolic compounds and lower activation energy values for extracts derived from vacuum-dried chicory root flour at 60ºC and 25 mm Hg pressure. Overall, the proposed mathematical model effectively predicted the described behavior with satisfactory accuracy.

Published: January 2025

The limited availability of water in the Cesar department (Colombia), along with the high-water consumption associated with the lack of knowledge of water requirements and the low efficiency of irrigation systems in the oil palm (Elaeis guineensis Jacq.) crop, has led to an inefficient use of water resources and affected the crop productivity. The main objective of this research was to determine the water demand of oil palm cultivated in areas with homogeneous agroclimatic conditions in the Cesar department. For this purpose, climatic information of the department was obtained from meteorological stations and climatic satellite data. The water demand was also determined by obtaining the crop coefficient (Kc) for plants aged 10 and 15 years, using the water balance methodology. The Kc obtained was 0.91 and 0.84, respectively. As a result of the zoning, 10 agroclimatic zones were identified in the department, of which 8 were found to be suitable for oil palm cultivation. In these zones, water requirements are expected to be homogeneous due to similar soil and climate characteristics. This information was used to estimate the regional water balance, allowing farmers to plan water management and optimize the use of available resources.

Published: January 2025

Morinda citrifolia L. is a plant utilized for its food and medicinal benefits. However, a lack of information on its nutrient requirement limits the yield potential of this crop for commercial cultivation. Therefore, the response of noni seedlings to the application of complete nutrient solution with or without omission of one macronutrient (to determine the most limiting one) was studied. The treatments consisted of 7 nutrient solutions (Complete Nutrient Solution (CNS) and CNS minus (-) each of N, P, K, Mg, Ca, and S) and four application volumes (0 ml (control), 100 ml, 200 ml, and 300 ml NS) arranged in a randomized complete block design with four replicates in a greenhouse. Data on stem height, stem diameter, number of leaves, leaf area, and visual nutrient deficiency symptoms were assessed at four weeks intervals, starting from the 4th week after transplanting (WAT) in sand culture. Total dry matter yields and leaf chlorophyll content were determined at 20 WAT. The seedlings treated with CNS presented the highest growth in terms of all the variables, with no deficiency symptoms, whereas seedlings treated with CNS-N had the least growth, chlorotic leaves, and a stunted appearance throughout the period of the study. Overall, the order of growth limitation in seedlings was as follows: -N˃-Ca˃-Mg˃-P˃-K˃-S˃CNS. The seedlings treated with 100 ml NS had the best performance as compared to the control and other treatments. These results indicated that N followed by Ca and Mg are the most limiting macronutrients for noni seedling development and are required in relatively small quantities.

Published: January 2025

Las definiciones alrededor de la Adaptación basada en Comunidades -AbC- ante el cambio climático trascienden lo biofísico y se preguntan por el marco de acción local y por la interacción entre saberes instaurados en los territorios de actores gubernamentales, políticos y académicos. Este artículo desarrolla una revisión bibliográfica de alrededor de 300 textos publicados entre 2009 y 2022, alojados en Scopus y en repositorios de datos abiertos de instituciones de investigación de América Latina bajo la metodología Prisma, y analizados mediante Bibliometrix e Inteligencia Artificial, para revelar diversas acepciones de AbC y la relación de las comunidades con la adaptación al cambio climático. Se advierte la necesidad de reconocer el rol de diversos actores, entre ellos las comunidades y sus conocimientos locales en la dinamización de acciones en torno a los efectos del cambio climático, dado que los Estados desatienden el accionar localizado y el saber de estas en sus acciones de adaptación; sin embargo, los eventos asociados modifican los comportamientos, los medios de vida, la salud, las prácticas del habitar y la infraestructura natural y construida, pero no los roles de género, lo que revela la necesidad de miradas diferenciales, interseccionales y participativas multiescalares.

Published: January 2025

En América Latina y Argentina, el desarrollo urbano-territorial tiende a un modelo de crecimiento que deriva en una profundización de las desigualdades y conflictos socio-territoriales y ambientales. En este sentido, el rol de los gobiernos locales en la promoción de políticas urbano-habitacionales sostenibles que mitiguen, incorporen adaptaciones y reduzcan las vulnerabilidades socioambientales en las ciudades, muchas veces se ha visto superado en cuanto a su capacidad de accionar frente a las nuevas exigencias del contexto.
El objetivo de este trabajo se centra en el análisis de las capacidades para una gestión sostenible del hábitat disponibles en municipios pequeños e intermedios de la Región Centro de Argentina.
A través del estudio de casos y desde abordajes cuanti-cualitativos, se reconocen y estudian críticamente las capacidades existentes o pendientes en este tipo de municipios en relación al objetivo planteado.
Para ello se incorporan las nociones de localidad y la importancia de la sostenibilidad institucional, junto a la incorporación de ejes y criterios provistos por las contra-agendas de organizaciones sociales como factores claves a promover para avanzar hacia un modelo de gestión territorial y habitacional sostenible transformador.

Authors: Gomez-Perez Juan , Muñoz García Jorge Sebastián
Published: January 2025

Este trabajo evalúa el comportamiento de las emisiones de Gases Efecto Invernadero (GEI) de la ciudad de Medellín (Colombia) en el marco del primer corte de evaluación del Plan de Acción Climática (PAC) de la ciudad. Para ello, proponemos una metodología de cálculo a partir de las bases de datos abiertas de la Superintendencia de Servicios Públicos de Colombia. Esta metodología es capaz de reproducir los resultados de los inventarios pasados del municipio de Medellín con un error del 8%. A partir del modelo propuesto evaluamos la tendencia de cumplimiento de las metas de reducción de emisiones establecidas en el Plan de Acción Climático de Medellín. En el periodo evaluado hubo una reducción del consumo energético (electricidad, gas natural, gas licuado y carbón) del 13.6% y como consecuencia una reducción del 40.5% de emisiones entre el 2015 y el 2022. Finalmente, presentamos algunos datos que demuestran la transformación del modelo de desarrollo económico de la ciudad, por el cual el sector terciario de la economía tiene un mayor peso porcentual y un mejor desempeño en términos de consumo por cada COP generado como valor agregado.

Trade Responses to Climate Change in Low-income Developing Countries
Authors:   Korea Association for International Commerce and Information, Yun Sungjong
Published: January 2025

This paper examines trade responses to climate change in low-income developing countries through literature review. Low-income developing countries need collaborative solutions that take into account both their economic development needs and their carbon emissions realities to achieve inclusive economic development and climate goals simultaneously. In addition, a clear understanding of the impact of climate change on one's own country and other countries is necessary in terms of international competitiveness and comparative advantage. When considering policies to reduce or adapt to the negative impacts of climate change, the specific level of economic development of a country and its institutional and technological capacity to address climate change must be taken into account. The international community should not spare effective technology transfer and financial support for low-income developing countries.
Quantification of building performance to evaluate novel design methods
Authors: Musial Anna , Singh Atwal Harkaran , Torero José L.
Published: January 2025

A framework is proposed to characterize in a holistic and quantitative manner the performance of buildings. This framework aims at using continuous performance assessment, from the design conception through the life of a building. The quantitative assessment will allow designers to move away from thinking of buildings a prototype that provides no feedback loop to designers towards analysing buildings as living laboratories that inform novel design approaches. To understand the value of the framework and any factors limiting its application a biomimicry approach was used as an example. Biomimicry principles capitalize on evolution to deliver continuous quality improvement and therefore these principles were found to be consistent with modern design objectives. A series of high-profile buildings were analysed based on publicly available data. Six buildings were shortlisted for a more in-dept analysis, nevertheless it became evident that for all these buildings there was insufficient data analysis, against the design objectives, to enable a holistic assessment of performance. To illustrate the weaknesses in the data set, the best documented building, the Council House Building (CH2) in Melbourne, Australia was analysed and areas where data was missing were established.

A summary of Marine Turtle records for Norfolk Island
Authors:   Queensland Museum, Pendoley Kellie , Christian Margaret
Published: January 2025

Nothing has been published in the modern literature on the status of marine turtles at Norfolk Island although their presence has been recognised since 1793 (Fidlon & Ryan 1980). This study brings together all the available published, anecdotal and field survey data on marine turtles at Norfolk Island so that the status of habitat usage could be established. The results confirm the Norfolk Island group is used for foraging by resident adult and juvenile Chelonia mydas (Green) turtles and adult Eretmochelys imbricata (Hawksbill) turtles. The natal beaches for these resident animals are thought to be Melanesian and Polynesian islands to the north and the beaches of north eastern Australia. While juvenile hawksbill turtles have not been recorded foraging at Norfolk Island they are the most common species and age class recorded in the island’s strandings data. The confirmation of marine turtles at Norfolk means that any future development proposals must include assessment of project impacts on these listed threatened species under Australian Federal legislation and their marine bioregional processes.
Podcasting in Serbia: Podcasters’ Perspectives on Emerging Roles, Practices, and Functions
Authors: Žikić Simona , Markov Čedomir
Published: January 2025

Podcasting has become increasingly popular in Serbia, a hybrid regime country characterized by profound polarization, a lack of media professionalism, and widespread anti-press sentiment. This study aimed to explore how podcast creators view their roles and practices within the evolving media landscape, as well as the implications of podcasting’s growing popularity in the Serbian public sphere. The data were obtained through focus groups with 16 independent and mainstream media-affiliated podcasters, exploring their perspectives on podcasting’s distinctiveness, functions, affordances, and obstacles. Participants noted the ability of podcasts to provide in-depth analysis of often neglected topics due to their flexible, informal presentation style, as opposed to the perceived routinization, rigidity, and superficiality of traditional media. Podcasters affiliated with professional media described podcasting as an extension of their practices, providing behind-the-scenes insights and additional journalistic content, whereas independent podcasters prioritized genuine conversations to create resonant content tailored to specialized communities. Journalist podcasters attributed the appeal of podcasting to the authenticity and intimacy it creates but emphasized the struggles of matching these features with journalistic standards. While most participants believed that podcasting contributes to greater external pluralism by providing a space for neglected subjects, alternative narratives, and marginalized voices, some were concerned about the possibility of exacerbating polarization, as podcasts frequently serve divided audiences. By exploring the perspectives Serbian podcasters bring to production and the meanings they attach to their roles and practices, this study offers insights for scholars and practitioners exploring media innovation in hybrid regimes and emerging democracies.

THE HISTORY OF DEVELOPMENT OF UKRAINE’S RELATIONS WITH AUSTRALIA
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Kopiika Valerii , Troian Pavlo ,   Embassy of Ukraine in Australia
Published: January 2025

The article discusses the main milestones in the development of Ukrainian-Australian relations since the early 1990s up to the present day. Australia recognized Ukraine as a sovereign and independent state on December 26, 1991, and on January 10, 1992, diplomatic relations were established between the two states. However, the Embassy of Ukraine in Australia was opened only on April 14, 2003. The official visit of the Australian parliamentary delegation to Ukraine in June-July 2004 became the important evidence of support for the statehood democratic course of Ukraine. The first visit of the President of Ukraine to Australia took place in December 2014.

The investigation of the MH17 plane crash gave the impetus for the intensification of relations between Ukraine and Australia. During the terrorist attack, 38 Australian citizens were killed. This event strengthened Australia’s empathy for Ukraine, which is waging a fierce existential war against the aggressor country Russia. Ukraine and Australia signed the “Agreement between Ukraine and Australia on the Deployment of Australian Personnel to Ukraine in Connection with the Crash of Malaysia Airlines Flight MH17” (2014).

Russia’s full-scale invasion of the territory of Ukraine on February 24, 2022, was another milestone in the history of relations between Ukraine and Australia. Ukraine was the first state visited by Australian Prime Minister Anthony Albanese (July 3, 2022). Australia supports Ukraine at the diplomatic and political level.

BACKGROUND: The 3D printing technology is rapidly developing, giving the opportunities for the manufacturing of parts with specified properties. However, the mechanical characteristics of materials obtained by 3D printing often do not meet the requirements for various applications, for example, agricultural machinery. Increasing the impact strength of materials produced by 3D printing is a relevant task for expanding their application.
OBJECTIVE: Study of the effect of heat treatment (annealing) and 3D printing parameters (layer thickness, filling percentage) on the impact strength of the polylactide (PLA) samples.
METHODS: An experimental study was conducted using the PLA samples made by 3D printing with variable parameters: layer thickness (0.15 mm, 0.20 mm, 0.25 mm) and percentage of filling (50%, 75%, 100%). The samples were annealed at a temperature of 80 °C for 2 hours. The impact strength was determined by the Charpy method using standard test equipment.
RESULTS: 27 PLA samples were included in the study. Annealing significantly increases the impact strength of all samples. The dependence of the impact strength on the thickness of the layer and the percentage of filling was observed. The maximum impact strength (2.58 ± 0.12 J/cm2) was achieved with a layer thickness of 0.15 mm and 100% filling. Statistical analysis of the results performed using ANOVA (p 0.001) showed a significant influence of all factors on the impact strength.
CONCLUSIONS: The results obtained demonstrate that annealing and optimization of 3D printing parameters (layer thickness, filling percentage) can increase the impact strength of materials obtained by 3D printing from PLA. The optimal parameters achieved in this study can be used in development of parts of agricultural machines with improved mechanical properties.

This research examines how blockchain technology improves international commerce cybersecurity and efficiency. We want to see how blockchain enhances transparency, reduces costs, and streamlines global trading networks by addressing security risks and inefficiencies. Secondary data-based literature reviews, case studies, and industry reports are used to assess blockchain's trade potential. The research found that blockchain improves cybersecurity by decentralizing data storage, assuring immutability, and preventing fraud and data breaches. Automation via smart contracts, trade paperwork simplification, and supply chain visibility boost efficiency. However, scalability, interoperability, and regulatory issues persist. The report underlines that blockchain may lower costs by removing intermediaries and increasing direct peer-to-peer interactions. Standards, cross-border legislation, and incentives for blockchain implementation, especially for SMEs, have policy implications. It also emphasizes stakeholder engagement and capacity-building to overcome technical and financial hurdles. The research finds that blockchain may transform international commerce by making it safer, more efficient, and transparent, but it needs concerted governmental initiatives to overcome present constraints.

Beyond 5G (B5G) networks will deploy hybrid multi-radio access technologies for improved Spectrum Efficiency (SE) and Energy Efficiency (EE). For further capacity enhancement, code and power domain multiplexing are applied on hybrid Power Domain Sparse Code Nonorthogonal Multiple Access (PD-SCMA) schemes. In order to realize optimal performance, robust Resource Allocation (RA) policies are required with the best candidate for the complex overloaded B5G systems based on Artificial Intelligence (AI) techniques. This work develops a deep neural network (DNN) aided resource allocation scheme for an uplink PD-SCMA network with Near-User (NU) and Far- User (FU) groups, multiplexed in the power and code domain. The RA problem is formulated as a non-convex joint optimization problem then decomposed into three subproblems namely Codebook Assignment (CA), User Clustering (UC) and power allocation (PA). For the three sub-problems, a three-stage generic fully connected DNN is trained to approximate the PA, CA and UC resource allocation solution by the proposed modified Primal-Dual Interior Point Method (mPD-IPM). The proposed mPD-IPM generates the near-optimal RA solutions that form the DNN input labels. The DNN-mPD-IPM not only greatly enhances the computational efficiency but also achieves improved convergence rates and guarantees both the ergodic and nonergodic sum rates of the system compared to generic algorithms. Simulation results show that the DNN aided resource allocation closely learns the system capacity and computational performance of the proposed mPD-IPM and further outperforms generic RA algorithms. Compared to cross-layer codebooks, mPD-IPM and DNN-mPD-IPM achieves approximately 19% higher capacity. The proposed DNN-mPD-IPM that learns to approximate the proposed mPD-IPM has an execution time that is approximately 70% lower than mPD-IPM.

To assess clinical and radiological factors that predict difficult laparoscopic cholecystectomy.

Laparoscopic cholecystectomy is a complex surgical procedure involving anatomical variations, adhesions, and gall bladder contracting. Preoperative assessment is crucial for identifying risks and improving post-operative outcomes. The study identifies clinico-radiological factors predicting difficult laparoscopic cholecystectomy, improving preoperative planning, reducing conversion rates, and optimizing surgical preparedness and patient counseling for safer, more efficient practices.

A prospective observational study was conducted at the Department of General Surgery, Integral Institute of Medical Sciences and Research in Lucknow, involving 90 patients selected for Elective Laparoscopic Cholecystectomy and those with ultrasonographic ally proven cholelithiasis, excluding those with significant co-morbid illnesses or not fit for pneumoperitoneum creation. The study utilized IBM SPSS Stats 25.0 software for data analysis, presenting continuous data as mean±standard deviation and categorical/qualitative data as numbers and percentages.

Total 90 patients aged 15-70, with a majority female (77.8%), and a mean BMI of 18.5-30.0 kg/m2, with 48 patients under 25 kg/m2. A pre-operative scoring system for difficult laparoscopic cholecystectomy was developed using demographic, clinical, laboratory, and USG findings. The system ranged from 0-5 to 11-15 difficult surgeries, with a mean predictive score of 0-7. Most surgeries were predicted as easy, followed by difficult (18.9%) and very difficult (5.6%). Factors like age, BMI, hospitalization history, comorbidities, and abdominal scars were associated with ease of surgery.

The study assessed 90 patients aged 15-70 for difficult laparoscopic cholecystectomy procedures using a difficulty predicting scoring system, identifying factors like age, sex, hospitalization history, and BMI.
Role of insulin in the management of diabetic foot

Despite insulin's well-documented benefits in wound healing over the last 70 years, challenges remain regarding the optimal method of administration. While systemic insulin therapy has significant side effects, topical insulin faces challenges with consistent delivery. This study aims to test the hypothesis that local insulin injections can provide sustained high concentrations in wounds, promoting healing with minimal systemic impact, combining the benefits of both systemic and topical insulin therapies.

This study investigates the effect of local insulin injections on wound healing, focusing on enhancing the healing process in a non-healing diabetic foot ulcer. The objective is to determine whether insulin injections at the wound site can accelerate healing by promoting key processes like keratinocyte migration, differentiation, and angiogenesis.

Conducted at a tertiary care center in South India, this study involved a 69-year-old male patient with a non-healing ulcer over the lateral aspect of the left foot due to Charcot's joint. The wound area was treated with a mixture of Insulin Isophane and Human Insulin (70/30) in a 4-unit to 10 ml saline ratio per 10 cm². The treatment was followed by a two-layer regenerative scaffold dressing and Negative Pressure Wound Therapy (NPWT) to support recovery.

The insulin application significantly enhanced wound healing by promoting keratinocyte migration, differentiation, and angiogenesis. These effects led to a noticeable reduction in the time required for wound closure and improved tissue regeneration.

The use of local insulin injections effectively improves wound healing by targeting key processes such as inflammation, re-epithelialization, and angiogenesis. This study underscores the potential of insulin as a promising therapeutic agent for chronic wound management. Further research is recommended to validate these findings and explore its application across diverse wound types.
