Authors: Agarwal Nitin , Ashutosh  , Sharma Ashish , Gupta Arun 
Published: October 2023

Objective: Despite the high prevalence and poor outcome of skin and soft tissue infections (SSTIs), very few studies from India have dealt with the subject. We planned a prospective study of inpatients with SSTIs to study the aetiology, clinical presentation (severity) and outcome of patients with SSTIs in our facility. Method: Patients with SSTIs involving >5% body surface area (BSA) and/or systemic signs were admitted to the surgery department of a teaching tertiary level hospital in Delhi, India, and were clinically classified into cellulitis, necrotising soft tissue infections (NSTIs), pyomyositis, and abscess. Demographic and clinical variables such as: age; sex; occupation; history of trauma/insect or animal bites; duration of illness; presenting symptoms and signs; comorbid conditions; predisposing factors such as lymphoedema or venous disease; hospital course; treatment instituted; complications; hospital outcome; presence of crepitus, bullae, gangrene, muscle necrosis and compartment syndrome were recorded. The chief outcome parameters were death and length of hospital stay; others, such as abscess drainage, the need for plastic surgical procedures and amputations were also noted. Results: Out of 250 patients enrolled in the study, 145 (58%) had NSTIs, 64 (26%) had abscesses, 15 (6%) had cellulitis and 26 (10%) had pyomyositis. Mortality was observed with NSTIs (27/145, 19%) and with pyomyositis (3/26, 11.5%). Factors affecting mortality by univariate analysis in the NSTI group were: abnormal pulse; hypotension; tachypnea; bullae; increased blood urea and serum creatinine; inotrope or ventilator support (all with p<0.001); local tenderness, gangrene, dialysis support and BSA (9.33±6.44 versus 5.12±3.62; p<0.05 for the last four). No factor was found to be significant on multivariate analysis. Variables associated with hospital stay >12 days were immunocompromise, pus discharge, ulceration or gangrene, and after interventions such as blood transfusion, drainage or skin grafting. Conclusion: High prevalence of NSTI and pyomyositis with high mortality was observed in our SSTI patients, often in immunocompetent young individuals. Epidemiological studies focused on virulent strains of Staphylococcus aureus may be required to identify the cause, since Staphylococcal toxins have been implicated in other infections.

Data-Driven Health Innovation and Privacy Regulation
Authors: Conti Chiara , D’Annunzio Anna , Reverberi Pierfrancesco 
Published: October 2023

Abstract
Data-driven health innovation may lead to develop targeted treatments using health data. We consider privacy-sensitive patients who may decide to share personal health data if compensated. Each patient does not internalize the impact of sharing data on drug innovation. We show that investment incentives in targeted treatments are too weak as long as such innovation has a public good nature so that patients can free ride on sharing health data. Then, privacy protection measures reducing data sharing risks can promote pharmaceutical R&D and social welfare.
On initial value problem for elliptic equation on the plane under Caputo derivative
Authors: Binh Tran Thanh , Thang Bui Dinh , Phuong Nguyen Duc 
Published: October 2023

Abstract
In this article, we are interested to study the elliptic equation under the Caputo derivative. We obtain several regularity results for the mild solution based on various assumptions of the input data. In addition, we derive the lower bound of the mild solution in the appropriate space. The main tool of the analysis estimation for the mild solution is based on the bound of the Mittag-Leffler functions, combined with analysis in Hilbert scales space. Moreover, we provide a regularized solution for our problem using the Fourier truncation method. We also obtain the error estimate between the regularized solution and the mild solution. Our current article seems to be the first study to deal with elliptic equations with Caputo derivatives on the unbounded domain.

Published: October 2023

AbstractThe terahertz (THz) technology has fascinated lot of attention due to its enormous potential for a wide range of applications in the public, private and enterprise domains. This research work demonstrates the design structure and analysis of graphene based waveguide fed hybrid plasmonic THz patch antenna (HPTPA) constructed at around 3 THz. Hybrid plasmonic THz waveguide (HPTW) as a feeding line for the proposed THz patch antenna can increases antenna efficiency. The graphene is sandwiched between gallium arsenide (GaAs) and silver (Ag) to confine THz waves efficiently. Using mode analysis in finite element method for the proposed HPTW the propagation length, effective refractive index has been thoroughly examined. Based on the finite element method (FEM) approach, the results of the designed graphene-based waveguide fed HPTPA shows a high effective refractive index of 2.9, large propagation length of 230 µm, gain of 2.29 dBi, bandwidth of 200 GHz and efficiency of 85 % has obtained. The proposed graphene-based waveguide fed HPTPA could be beneficial to enable several photonic integrated circuit applications in next-generation wireless communication.

Published: October 2023

Abstract
The risk of flooding is a destructive natural hazard, and it is increasing due to heavy rainfall and anthropogenic factors. Hydrologic–hydraulic models serve as valuable tools for flood forecasting and predicting future flow patterns. These models evaluate and simplify processes in ungauged basins. In this study, three hydrologic models (soil conservation service [SCS], Snyder, and Temez) were used to calculate synthetic unit hydrographs for the Humaya and Tamazula River (H-T-R) basin. Additionally, the flows derived from the three models were simulated in Hydrological Engineering Center River Analysis System for various return periods (2, 5, 10, 25, 50, and 100 years). The accuracy of the models SCS, Snyder, and Temez was evaluated using the root-mean-square error (1162.44, 144.76, and 2890.6); Nash–Sutcliffe efficiency (−51.12, 0.19, and −312.28); R
2 (0.97, 0.94, and 0.94), and kappa index (0.8534, 0.9895, and 0.7155), respectively. The data used in this study were obtained from a hydrometric station located on the Culiacan River. The main findings indicate that the Snyder model demonstrated a better predictive capability compared to the Temez and SCS models, albeit with a tendency to overestimate. Simulated flood depths are deeper in the upstream areas, particularly upstream from the Musala Island bifurcation on the Tamazula River, with values of 11.82 m for SCS, 9.76 m for Snyder, and 13.5 m for Temez. The simulation revealed potential overflow zones along the Tamazula River, particularly at the channel bifurcation and near the confluence with the Humaya River, during the 100 year return period simulation.
High speed 60 Gbps RGB laser based-FSOC link by incorporating hybrid PDM-MIMO scheme for indoor applications

Published: October 2023

Abstract
Visible Light Communication (VLC) systems enhanced by red, green and blue (RGB) lasers are at the forefront of indoor technology, offering dynamic lighting, high-speed data transfer, and energy efficiency. This innovative combination not only revolutionizes connectivity and illumination but also ensures privacy and security, making it a game-changer for smart homes, offices, and various indoor applications. In our research, we introduce a polarization division multiplexing and Multiple Input Multiple Output based (PDM-MIMO) system that carries 60 Gbps of data over a transmission range of 500 m in free space Channels. The utilization of the cost-effective on-off key (OOK) modulation format is attributed to its affordability in our transmission scheme. For parallel data transmission, three laser diodes in RGB were utilized. To enhance both the transmission range and reduce the Bit Error Rate (BER), MIMO scheme is employed. Our study presents simulation outcomes, conducted using OptiSystemTM software, that focus on evaluating the bit error rates for the proposed PDM-MIMO link. Our findings demonstrate successful 60 Gbps data transmission over 350 m in FSO with an acceptable BER, reinforced by clear eye diagrams. Introducing MIMO expands the range to 500 m while improving BER, paving the way for real-time experimentation and research advancement.

Abstract
This meta-analysis aimed to evaluate the diagnostic accuracy of touch imprint cytology (TIC) for sentinel lymph node (SLN) metastases of patients with clinical node-negative early breast cancer. The PubMed, Web of Science, Embase, and the Cochrane Library databases were meticulously searched to retrieve literature published from January 2005 to September 2022 by two independent reviewers. The meta-analysis was performed using STATA16.0, Meta-Disc 1.4, and RevMan 5.4.9. According to the inclusion criteria, 4,073 patients from 13 studies were included in this meta-analysis. The pooled sensitivity and specificity of TIC for detecting SLN metastases were 0.77 (95% CI 0.66–0.85) and 0.99 (95% CI 0.97–1.00), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 76.15 (95% CI 29.16–198.84) and 0.23 (95% CI 0.15–0.36), respectively. The pooled diagnostic odds ratio was 326.82 (95% CI 132.76–804.56) and the area under the sROC curve was 0.97 (95% CI 0.95–0.98), respectively. This meta-analysis revealed that TIC with high sensitivity and specificity is a feasibility and accuracy diagnosis technique for intraoperative detection of SLN metastases in breast cancer.

Short-Story Writing as the Art of Ordinary Aesthetics
Authors: Gouverneur Michel-Guy 
Published: October 2023

AbstractThough ordinary aesthetics is self-evident as a principle, fruitful as a method, it remains partly undefined. It seems the major difficulty is to mark out its territory, so much so as, after Wittgenstein, it endorses the most part of what used to pertain to ethics. Our hypothesis is that starting from art forms may prove helpful in defining ordinary aesthetics; and the article suggests that short-story writing is a paradigmatic pathway to ordinary aesthetics as it is to the ethical unsaid.
Product of bi-dimensional VAR(1) model components.
An application to the cost of electricity load prediction errors

Published: October 2023

Abstract
The multi-dimensional vector autoregressive (VAR) time series is often used to model the impulse-response functions of macroeconomics variables.
However, in some economical applications, the variable of main interest is the product of time series describing market variables, like e.g. the cost, being the product of price and volume.
In this paper, we analyze the product of the bi-dimensional VAR(1) model components.
For the introduced time series, we derive general formulas for the autocovariance function and study its properties for different cases of cross-dependence between the VAR(1) model components.
The theoretical results are then illustrated in the simulation study for two types of bivariate distributions of the residual series, namely the Gaussian and Student’s t.
The obtained results are applied for the electricity market case study, in which we show that the additional cost of balancing load prediction errors prior to delivery can be well described by time series being the product of the VAR(1) model components with the bivariate normal inverse Gaussian distribution.

Published: October 2023

AbstractIn this study, nonlinear control design is presented for trajectory tracking of Tricopter system. A Fractional Order Proportional Derivative (FOPD) controller has been developed. The performance of controlled Tri-copter system can be enhanced by suggesting modern optimization technique to optimally tune the design parameters of FOPD controller. The Spotted Hyena Optimizer (SHO) is proposed as an optimization method for optimal tuning of FOPD's parameters. To verify the performance of controlled Tricopter system based on optimal SHO-based FOPD controller, computer simulation is implemented via MATLAB codes. Moreover, a comparison study between SHO and Particle Swarm Optimization (PSO) has been made in terms of robustness and transient behavior characteristics of FOPD controller.

Published: October 2023

An analysis of the state of nutrition of people in Ukraine shows that the population does not eat well, which significantly worsens the state of their health and working capacity. The solution to the problem is possible through changes in the structure of nutrition, and above all, through an increase in the diet of vegetables and fruits of high quality, the varieties of which have been created using biofortification strategies. Biofortification is an innovative and promising approach in solving global problems related to nutrition. The goal of biofortification is to create plants with increased levels of the necessary functional ingredients absorbed from the soil, as well as those synthesized in the plant. Biofortification strategies consist in the development of optimal ways of mineral nutrition of plants, the creation of new species using molecular genetic approaches, and the use of traditional breeding methods. The purpose of the research is to analyze the modern experience of creating varieties of various fruit and vegetable crops with the help of biofortification strategies, which have an increased content of functional ingredients. Based on the literature review, it was established that for many years, an unconventional direction of selection has been developing – the creation of varieties and hybrids of fruits and vegetables with the recommended chemical composition. Created varieties of vegetables and fruits with increased protein content (nuts and legumes); starch (potato); carotenoids, dry matter, disaccharides (carrot, pumpkin); vitamin C, betanin, sugars (table beet); selenium (tomatoes); bioflavonoids, vitamin C (cabbage vegetables); macro- and microelements (bulb vegetables), etc. Such raw materials can be used to create special purpose products, which will significantly improve the quality of the population's diet and health. It is shown that the development of the non-traditional direction in breeding remains promising, and the study of samples of the domestic collection of agricultural crops and the selection of the best varieties from them for various directions of use, and especially for the production of special purpose products, is an important national economic and scientific task of an innovative nature that must be developed, therefore that the problem of improving the nation should come first.
MICROWAVE AND ULTRASONIC TREATMENT AS A PRELIMINARY STAGE OF OBTAINING WATER-SOLUBLE MANNAN FROM COFFEE SLUDGE
Authors: Naumenko K. , Kapustian A. , Gural L. 
Published: October 2023

In recent years, interest in immunocorrectors of natural origin has increased significantly. Among them is a group of polysaccharides such as mannans. Mannans are polysaccharides composed of D-mannose residues as the main chain. They possess a number of properties: immunomodulatory, cancer-protective, antimicrobial, and normalize blood cholesterol levels. Mannans are present in a number of plants, algae and microorganisms. One of the promising sources of mannans can be coffee sludge, which is accumulated on an industrial scale at instant coffee companies. This article describes a biotechnological method for the production of water-soluble mannan from coffee sludge and investigates the possibility of increasing the yield of water-soluble low-molecular-weight mannan with the maximum content of physiologically active fractions by pretreating the raw material with ultrasound and ultrahigh-frequency radiation. The sludge was pretreated in an aqueous medium using ultrasound at 25, 35 and 40 kHz for 15 minutes and treatment in a 2.45 GHz ultra-high-frequency electric field with a power of 300 W, 600 W and 800 W for 5 minutes. Next, the physical disintegrate was treated with an enzyme preparation with beta-mannanase activity and centrifuged. The resulting water-soluble products were characterized by gel chromatography to determine the molecular weight distribution of the fractions of each sample. It was found that the pretreatment with ultrasound is expedient, since the total amount of fractions with a molecular weight of less than 20 kDa is almost 80%. The treatment of raw materials with microwave rays is inefficient and leads to an increase in fractions of molecular weight less than 1 kDa. Thus, varying the conditions of the preliminary physical treatment of coffee sludge allows to regulate the molecular weight distribution of water-soluble enzymolysis products and obtain products with the required range of molecular weight values.
