Wavelet -Based Modified Intermediate Significant Bit Insertion for Text Steganography
Authors: Qaswaa K. Abood
Published: April 2023

In this paper, we propose and investigate the use of a modifiedversion of Intermediate Significant Bit (ISB) insertion algorithm, so-called here as MISB algorithm for secret text steganography. The secret text is passed through a sequence of ciphering techniques. A Modified Intermediate Significant Bit MISB insertion algorithm is proposed for hiding the bit sequences of the cipher text into the time-frequency domain using wavelet transform of the image pixels, in order to improve the robustness of the Steganography system. Results demonstrate the effectiveness of wavelet Modified Intermediate Significant Bit WMISB while evaluating its performance using Peak Signal to Noise Ratio PSNR measure. Moreover, additional experiments are evaluated for noising, and image compression for cover images to compare their Peak Signal to Noise Ratio PSNR. The drawn results confirm the effectiveness of the proposed Wavelet-based Modified Intermediate Significant Bit Insertion WMISB, Also, Bit Error Rate BER, is a key parameter that is used in assessing systems that transmit digital data from one location to another.

Wealthy nations must step up support for Africa and vulnerable countries in addressing past, present and future impacts of climate change The 2022 report of the Intergovernmental Panel on Climate Change (IPCC) paints a dark picture of the future of life on earth, characterised by ecosystem collapse, species extinction, and climate hazards such as heatwaves and floods.1 These are all linked to physical and mental health problems, with direct and indirect consequences of increased morbidity and mortality. To avoid these catastrophic health effects across all regions of the globe, there is broad agreement—as 231 health journals argued together in 2021—that the rise in global temperature must be limited to less than 1.5oC compared with pre-industrial levels. While the Paris Agreement of 2015 outlines a global action framework that incorporates providing climate finance to developing countries, this support has yet to materialise.2 COP27 is the fifth Conference of the Parties (COP) to be organised in Africa since its inception in 1995. Ahead of this meeting, we—as health journal editors from across the continent—call for urgent action to ensure it is the COP that finally delivers climate justice for Africa and vulnerable countries. This is essential not just for the health of those countries, but for the health of the whole world.

Abstract Background: Terminalia avicennioides is a medicinal plant used traditionally in Nigeria to treat numerous ailments and disorders which include coughs, purgative and emetic. Objective: This study scientifically evaluated the probable mechanism of the anti-emetic activity of methanol root extract of Terminalia avicennioides Guill. & Perr. on histaminergic and serotonergic receptors of isolated rabbit ileum. Methodology: Fresh root bark was extracted using methanol and the antiemetic effect was evaluated by experimenting on a small segment (3 cm) of isolated rabbit ileum, using the data capsule (Ugo Basile) and single chamber isolated tissue apparatus. Varying concentrations of histamine and serotonin (0.05, 0.1, 0.2, and 0.4 mg/ml) were used to obtain contractions as they act on histamine and serotonergic receptors respectively. Results: META (0.05 mg/ml, 0.1 mg/ml, 0.2 mg/ml, and 0.4 mg/ml) exhibited a significant concentration-dependent decrease at p<0.05 in histamine-induced and serotonin-induced contractions on isolated rabbit ileum from the data capsule reading with percentage inhibition of 43.22, 53.96, 75.35, 85.58 % and 21.62, 49.50, 78.67 and 86.96 % respectively for the different concentrations. Conclusion: The study showed that methanol root extract of Terminalia avicennioides acts on cholinergic (muscarinic), histaminergic, and serotonergic receptors of isolated rabbit ileum by inhibitory spasmolytic action against smooth muscle contractility, hence its ability to possess anti-emetic effect to relieve vomiting.

PREVALENCE OF GLYCOPEPTIDE RESISTANCE IN COAGULASE NEGATIVE STAPHYLOCOCCI IN A TERTIARY CARE MULTISPECIALITY CENTRE
Authors: Tiwari Suman , Sarwat Tarana , K. Kakru Dalip
Published: April 2023

Background: Coagulase Negative Satphylococci (CoNS) were once thought to be non-pathogenic skin contaminants
when recovered from culture media, but the usage of intravenous and implantable devices and increase in the number of
immune - compromised patients in hospitals, they have now emerged as a major contributor of hospital acquired infections. The number of
CoNS with enhanced resistance to glycopeptides (especially vancomycin) has been observed to be on the rise in the recent decades. Therefore,
this research was done to recognize the clinical isolates of CoNS and to recognize various drug resistance with distinct mention to Vancomycin.
Aim: This study aimed to isolate Coagulase Negative Staphylococci from different clinical specimens and to determine antimicrobial
susceptibility pattern of all the isolates. From January 2021 to December 2021, Methods: this study was conducted in the Department of
Microbiology at the School of Medical Sciences & Research, SMSR, Sharda University, Greater Noida. Total 341 CoNS were recovered in 1
year duration time from various clinical samples. Descriptive statistics like frequency table, mean, proportions were used. Analysis was done by
SPS software. A total of 341 isolates of coagulase negative staphylococci Results: (CoNS) were obtained from various specimens out of which
150 (44%) were found to be clinically signicant. Maximum number of clinically signicant CoNS were recovered in the age group 0-9 years 29
(19.3%) followed by age group, ≥ 60 years: 27 (18%). Clinically signicant CoNS were isolated in maximum number from blood samples
(n=51, 34%) followed by pus (n=35, 23.3%). Samples received from patients housed in the neonatal intensive care unit yielded the maximum
number of clinically signicant CoNS isolates, 31 (20.7%). Staphylococcus.epidermidis was found to be the most commonly associated
clinically signicant CoNS with infection 72 (48%) followed by Staphylococcus haemolyticus 42 (28%). MIC by microbroth dilution and E test
was also done on all clinically signicant isolates of CoNS for vancomycin, all isolates were within the susceptible range with none of the
isolates being resistant to vancomycin(with MIC =<4µg/ml). It is thus concluded Conclusions: that isolation of CoNS and their antibiotic
susceptibility pattern should be regarded with all seriousness in clinical practice and clinical epidemiology because by being resistant to multiple
antibiotics, (methicillin resistant CoNS in particular), their prevalence not only limits the treatment options but also acts as a reservoir of drugresistant genes
ASSOCIATION OF SERUM C-REACTIVE PROTEIN AND D-DIMER CONCENTRATION WITH CLINICAL SEVERITY CAUSED BY CORONAVIRUS IN HOSPITALIZED PATIENTS WITH DIABETES
Authors: Dario Vui med.
Published: April 2023

BACKGROUND: The aim of this research was to compare the levels of inammatory markers (D-dimers and Creactive protein) in diabetic and non-diabetic patients depending on severity of clinical manifestation, therefore based on
such, dene them as potential predictors of lethal outcome and clinical severity. A total of 422 subjects were included in this METHODS:
research by retrospective review of the documentation at the Clinic for Infectious Diseases of University Clinical Hospital Mostar. While
reviewing the medical records, the following data were lled in: demographic (age, sex, diabetes mellitus), oxygen saturation and paO2/O2
ratio, inammatory markers (C-reactive protein and D-dimers), used therapy (non-invasive ventilation, oxygen therapy, invasive mechanical
ventilation) and nal outcome of disease. Based on the presence of diabetes mellitus the patients were divided into two groups: diabetic and nondiabetic patients. Data entry into tables was followed by statistical data processing using IBM SPSS Statistics v.26 and Microsoft Excel 2016.
RESULTS: Out of total number of subjects, 161 had diabetes and 261 did not. Surprisingly, women statistically had a higher average value of Ddimers in comparison to men and they had a higher percetage of lethal outcome compared to men. Deceased patients had a higher average value
of CRP (126,25) and D-dimers (2,20) in comparison to survivors. Also, the deceased had a lower average of oxygen saturation (83,07), lowered
paO2/O2 ratio (131,5) and more liters of oxygen used in oxygen therapy (11,59). Statistically signicant higher lethality was noted in patients
with diabetes compared to non-diabetic patients. Levels of C-reactive protei CONCLUSION: n and D-dimers were higher in patients with a
more severe clinical manifestation. Since lethal outcome was more statistically prevalent in those subjects, CRP and D-dimers are stated as
prognostic factors of clinical severity and lethal outcome in patients with COVID-19. Lastly, there was no notably increased difference in CRP
and D-dimer levels between diabetic and non-diabetic patients.
Current-Based Automated Design of Realizable Metasurface Antennas with Arbitrary Pattern Constraints
Authors: Zucchi Marcello , Vernì Francesco , Righero Marco , Vecchi Giuseppe
Published: April 2023

We present a 3D method to numerically design a realizable metasurface, which transforms a given incident field into a radiated field that satisfies mask-type (inequality) constraints. The method is based on an integral equation formulation, with local impedance boundary condition (IBC) approximation. The procedure yields the spatial distribution of the impedance, yet the process involves the synthesis of the equivalent current only. This current is constrained to correspond to a realizable surface impedance, i.e., passive, lossless, and with reactance values bounded by practical realizability limits. The current-based design avoids any solution of the forward problem, and the impedance is obtained from the synthesized current only at the end of the process. The procedure is gradient-based, with the gradient expressed in closed form. This allows handling large metasurfaces, with full spatial variability of the impedance in two dimensions. The method requires no a priori information, and all relevant operations in the iterative process can be evaluated with O(N logN) complexity. Application examples concentrate on the case of on-surface excitation and far-field pattern specifications; they show designs of circular and rectangular metasurface antennas of 20 wavelengths in size, with pencil- and shaped-beam patterns, and for both circular and linear polarization.

Authors: Patel Amit , Prakriya Shankar
Published: April 2023

In this paper, we analyze (for the first time in literature) the secrecy performance of a two-hop cooperative network in which all the nodes are of the energy-harvesting self-sustaining type. Both source and relay harvest energy from a power beacon (PB) and employ the harvest-use (HU) architecture. We consider optimal combining of the direct and relayed signals at the destination and eavesdropper. We do not assume any channel state information (CSI) at the source. We derive an approximate closed-form expression for secrecy outage probability assuming selective decode-and-forward (SDF) protocol at the relay. We demonstrate that secrecy outage is a convex function of the transmit power of PB. Further, the security-reliability trade-off (SRT) is analyzed to highlight the trade-off between outage and intercept probability. Computer simulations validate the derived analytical expressions
Convex Hull of Ellipsoids: A New Tool for Constrained Control of Uncertain Time-Varying Linear Discrete-Time Systems
Authors: Hoai Nam Nguyen
Published: April 2023

In this paper we address the problem of determining convex conditions for the convex hull of ellipsoids to be robustly invariant. The motivation for the study is from the vertex control. Based on the convex hull of a set of vertices, necessary and sufficient conditions were suggested in the literature for the stability analysis and controller design problems of a constrained uncertain time-varying linear discrete-time system. However it is not trivial to compute the vertices, especially for high dimensional systems. In the present paper, we propose to replace the convex hull of vertices by the convex hull of ellipsoids. The associated ellipsoids are not required to be robustly invariant. The conditions are given in terms of linear matrix inequalities (LMIs). Hence the main drawback of vertex control is removed. The conditions are losslessly extended to stabilization, providing then an LMI solution to the non-linear state feedback control design problem of constrained uncertain time-varying linear discretetime systems. Several examples are included with comparison to earlier solutions from the literature to illustrate the results.
DC Inductor Design using the Unique Air Gap Equation
Authors: Barg Sobhi
Published: April 2023

this paper presents a new design method of  the DC inductor using the unique air gap equation. The  uniqueness of the air gap equation is demonstrated using  different mathematical methods. The equation used in the  literature for the air gap calculation is ambiguous and can  easily lead to misconceptions of its dependency on the core  cross section. Furthermore, this paper investigates the effect of changing the relative permeability and the  inductance value on the number of turns and the air gap. An advantage of the proposed method is it gives a good understanding of the interdependence between the  inductance variables. Its main features are: (1)  straightforward design flow of the DC inductor, (2) low  optimization time and (3) better accuracy.

Published: April 2023

HVDC networks play an ever-more-significant role in today's and future power systems due to the rapid adoption of intermittent energy sources. In order to maximize the utilization of transmission grids for power systems with high share of renewable energy sources (RES) there is a need for an adequate quantification tool that is capable of accurately representing the uncertain operational characteristics of RES along with reflecting the control capabilities of HVDC converter stations. In that manner, the development of such a tool as a non-sampling one-shot mathematical structure is invaluable from the operational decision making point-of-view. This paper presents a mathematical chance-constrained framework for solving stochastic optimal power flow problem for hybrid AC/DC grids, which includes HVDC controllability and the uncertainties brought about by load and renewable energy generation, by using an intrusive general polynomial chaos approach. Three case studies are conducted on 5-bus and 67-bus hybrid AC/DC test systems to highlight the efficacy of the proposed method with a focus on the added flexibility of HVDC converters and the effects of various chance-constraint levels as well as to validate the method against Monte-Carlo simulations.
Task-Aware Distributed Inter-Layer Topology Optimization Method in Resource-Limited LEO-LEO Satellite Networks
Authors: Guo Ningxuan , Liu Liang , Zhong Xiaoqing
Published: April 2023

Due to the increasing demand for real-time observation data, remote-sensing satellites can be considered as users to access mega communication constellations, which can constitute a Low Earth Orbit (LEO) Double-Layered Satellite Network (DLSN) composed of Remote-sensing Layer Satellites (RLSs) and Communication Layer Satellites (CLSs). In this LEO DLSN, a Distributed Inter-Layer Topology Optimization (DITO) method is proposed based on time-space relationships between two layers, which can maximize task-aware observation benefits with limited onboard resources. For practical purposes, we take link switching interval constraints into account for the recapture and track of laser communicators. Besides, we put forward a new time-slot division method based on the link switching interval for the linear modeling of the time-sequential coupling problem. With the simulation results in four constellation systems, the proposed distributed interactive method can obtain an optimal solution close to the centralized global solution with much less time. Simulation analysis indicates that the work of this paper can support onboard optimization for future space networks.

Published: April 2023

Numerous studies have been conducted on the connection between music and the brain, and it has been established that listening to music directly affects brain activity and stimulation. The potential benefits of music therapy, which uses music as a tool for healing and fostering well-being, have come to light in a number of circumstances. However, there is a gap in understanding the effects of Indian classical music (ICM) on the brain and its therapeutic applications. In this work, the authors propose a systematic approach for identifying brain regions evoked to live ICM stimuli, considering input and output uncertainties. The brain responses are captured through 24 channel Electroencephalogram (EEG) cap, which is utilized to allocate electrodes to different regions of the brain. The proposed region specific near-automated framework based on eigen perturbation framework provides a measure to capture the time evolution of brain activity for the melodic transition or transition from a raga to relaxation triggered by Indian classical music. This identification is relevant in understanding dynamic changes in brain responses during musical experiences providing a more comprehensive perception and processing of ICM in the human brain. This automated approach can help integrate it into evidence-based music therapy for cognitive, emotional, and psychological conditions. Probabilistic analysis based on extensive experimental studies with live Indian classical vocal stimuli brings forth many interesting results that are worth delving into for future directions in music therapy. The findings of this study provides evidence indicating ragas activate different brain regions based on listener's musical knowledge.
Hedonic and Utilitarian Santri in Halal Product Consumption Behavior
Authors: Arafah Nawal Nur
Published: April 2023

The global trend towards halal products is considered one of the driving forces for the growing popularity of Halal products among the public. One of the aspects that consumers pay attention to in consuming halal products is whether the product has hedonic or utilitarian values. Some research on hedonic and utilitarian values had been previously conducted in the context of online buying behavior but did not focus on halal products. This study aims to investigate the impact of hedonic and utilitarian values on the consumption behavior of halal products. The study uses a questionnaire survey to collect data from 180 students in Magelang Regency. Structural Equation Model- Partial Least Square (SEM-PLS) analysis was performed to test the validity and hypothesis. The study shows that hedonic and utilitarian values significantly influence the consumption of halal products. The findings of this study indicate that halal products have more important hedonic benefits than utilitarian benefits in increasing consumption behavior.

This report focuses on collecting and analyzing external and internal noise levels generated by the modified transverse rumble strips on US-41 that were reconstructed in October 2022. The goal is to enable a comparison with noise levels generated by the previous rumble strips that were constructed in the same location in 2019. This work is organized in three tasks: (1) observe and document the construction of the 2022 transverse rumble strips, (2) collect US-41 traffic flow data as well as external and internal noise levels generated by the 2022 transverse rumble strips, and (3) compare the collected external noise levels generated by the 2022 US-41 rumble strips to those generated by the 2019 US-41 rumble strips that were collected and reported in the related 2021 study. The comparison results demonstrate that the time-equivalent continuous sound pressure level (Leq) generated by the 2022 US-41 transverse rumble strips at the AASHTO T 390-recommended measurement distances of 25 and 50 feet were lower than those reported in the 2021 study.

The aim of the research was to study the features of distribution of impurity metals in the distillates of several types of heavy oil produced in Uzbekistan, mixed with gas condensate. It has been revealed that the basic mass of impurities in the original oil is represented mainly by calcium salts of petroleum acids. Thermal decomposition of impurity metal naphthenates is accompanied by formation of highly corrosive organic acids. The concentration of organometallic compounds V, Ni, Fe and other d-elements in the oils produced in Uzbekistan is comparatively less than of the heavy oils in the known deposits of the Middle East and Russia. However, the corrosion activity of petroleum acids, together with the presence of hydrogen sulfide in the reaction medium, causes a sharp increase in impurities in the feedstock supplied to hydrotreating, in the form of a mixture of FeO(OH), FeO, Fe2O3 , Fe0 , Fe 1-хS, FeS and CaS. It has been proven that for producing of environmentally friendly commercial fuels and oils, as well as ensuring long-term operation of catalysts for hydrotreating distillate and residual fractions obtained by processing local hydrocarbon raw materials, it is recommendable to use special protective layers that actively extract corrosion products, along with compounds such as naphthenates of calcium, nickel and iron.

This study investigated the cognitive sphere in young and middle-aged patients with hypothyroidism. The aim of the study was to determine the dependence of cognitive impairment on the severity of hypothyroidism and the duration of the disease history. Despite advances in understanding the metabolism and the impact of thyroid hormone on the human brain, the scientific debate over the reversibility of neuropsychiatric disorders in hypothyroidism continues. There have been many studies about the relationship between neuropsychiatric disorders and hypothyroidism among newborns, children, the elderly, as well as in conjunction with other pathologies such as stroke, myocardial infarction, chronic cerebral ischemia, metabolic syndrome, etc. However, a neuropsychological study in young and middle age period patients suffering hypothyroidism, with the exclusion of another pathology, was not carried out. The neuropsychological examination was carried out in 61 patients with clinical and biochemical signs of hypothyroidism before and after replacement therapy. Patients were divided into test groups according to the severity of hypothyroidism and the duration of the history. The research findings showed the prevalence of cognitive impairments in basic groups of patients compared with the test ones. It is interesting, that different types of cognitive functions are affected in varying degrees. The findings can be used in endocrinology, neurology, therapy, practice of family doctors, in teaching university- and master course students as well as physicians . It has been established that disorders of higher cortical functions are directly proportional to the severity of hypothyroidism and the duration of illness; moreover, replacement therapy is not effective enough to restore cognitive function.

Silver nanoparticles stabilized in sodium-carboxymethyl cellulose (Na-CMC) solution with degree of substitution 0,65-0.85 and degree of polymerization 200-600 were synthesized. The structure, physico-chemical, mechanical properties and bactericidal activity of films obtained from solutions of Na-CMC containing silver nanoparticles were studied. The shape and size of silver nanoparticles in structure of Na-CMC films were determined using atomic force microscopy and UV - spectroscopy. It is established that with an increase in silver nitrate concentration in Na-CMC solutions and film, the size and shape of silver nanoparticles changed during photo irradiation. Studies have shown that the shape, size and number nanoparticles of silver determined their biological activity. It was found that an increase in the number of silver nanoparticles with sizes of 5-25 nm contributes to an increase in the bactericidal activity of Na-CMC films. A basic technological scheme and production technology for the biodegradable bactericidal Na-CMC films contained silver nanoparticles with specified dimensions with bactericidal and bacteriostatic properties, intended for the treatment of burns and trophic ulcers, have been developed.

In fact, the pathogenesis of the coronavirus disease has not been closely investigated, therefore frequent change of the virus strain keeps the clinic of the disease changing, the lack of a single therapeutic tactics, leads to the fact that this catastrophe continues to-date. In this article, we have presented the data retrieved from CVD-19 patients by the Republican Specialized Hospital of Zangiotа No. 2 in June. The main purpose of the scientific observation is to conduct a clinical analysis of all patients diagnosed with Covid-19 within a month. We have studied the medical histories of all patients (age, gender, concomitant diseases, dates of their stay in hospital, results of examination, tests, and medical treatments). From observations, it became clear that in June, mostly male, middle-aged and young people had gotten treatment in hospital; the review of frequency of concomitant diseases showed that the most common ones were diabetes mellitus and coronary heart disease in middle-aged people, hypertension – in the elderly, and bronchitis was more often registered in young people. According to the analysis of diseases of digestive system, pancreatitis and cholecystitis had prevailed in female patients, while gastritis – in males. Liver enzymes showed an increase in Ast and Alt. From the observations, it can be concluded that in June, the largest number of those infected were young and middle-aged males. Concomitant diseases were more common in young people, which indicates to rejuvenation of the diseases. An increase of liver enzymes may be associated with drugs used for treatment of the coronavirus disease.
