On asymptotics of solutions for superdiffusion and subdiffusion equations with the Riemann-Liouville fractional derivative
Authors: Li Zhiqiang , Fan Yanzhe
Published: June 2023

In the present paper, we focus on the study of the asymptotic behaviors of solutions for the Cauchy problem of time-space fractional superdiffusion and subdiffusion equations with integral initial conditions, where the Riemann-Liouville derivative is used in the temporal direction and the integral fractional Laplacian is applied in the spatial variables. The fundamental solutions of the considered equations, which can be represented in terms of the Fox $ H $-function, are constructed and investigated by using asymptotic expansions of the Fox $ H $-function. Then, we obtain the asymptotic behaviors of solutions in the sense of $ L^{p}(\mathbb{R}^{d}) $ and $ L^{p, \infty}(\mathbb{R}^{d}) $ norms, where Young's inequality for convolution plays a very important role. Finally, gradient estimates and large time behaviors of solutions are also provided. In particular, we derive the optimal $ L^{2} $- decay estimate for the subdiffusion equation.

Published: June 2023

Bone age assessment is of great significance to genetic diagnosis and endocrine diseases. Traditional bone age diagnosis mainly relies on experienced radiologists to examine the regions of interest in hand radiography, but it is time-consuming and may even lead to a vast error between the diagnosis result and the reference. The existing computer-aided methods predict bone age based on general regions of interest but do not explore specific regions of interest in hand radiography. This paper aims to solve such problems by performing bone age prediction on the articular surface and epiphysis from hand radiography using deep convolutional neural networks. The articular surface and epiphysis datasets are established from the Radiological Society of North America (RSNA) pediatric bone age challenge, where the specific feature regions of the articular surface and epiphysis are manually segmented from hand radiography. Five convolutional neural networks, i.e., ResNet50, SENet, DenseNet-121, EfficientNet-b4, and CSPNet, are employed to improve the accuracy and efficiency of bone age diagnosis in clinical applications. Experiments show that the best-performing model can yield a mean absolute error (MAE) of 7.34 months on the proposed articular surface and epiphysis datasets, which is more accurate and fast than the radiologists. The project is available at https://github.com/YameiDeng/BAANet/, and the annotated dataset is also published at https://doi.org/10.5281/zenodo.7947923.
Does vitamin D level have effect on COVID-19 outcomes?
Authors: Martin Marcus , Thompson Reinand , Tirupathi Nikhil
Published: June 2023

The severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), a type of coronavirus that causes the condition known as coronavirus disease, was first reported in Wuhan, China in 2019. It commonly affects the respiratory system and is known to produce, in some cases, pneumonia like symptoms, and even death. However, 25 hydroxyvitamin D commonly known as vitamin D, is, when in its hormonal form, involved in many processes throughout the body, including bone health and immune function. Several studies have linked vitamin D to increased resistance to infection, but the link between vitamin D levels and COVID-19 infection, severity and mortality is yet to be fully ascertained. Several studies have linked vitamin D serum levels and deficiency to differing levels of COVID-19 outcome. This review seeks to investigate these claims made in these studies to help add to the body of knowledge and come to a greater understanding of the link between vitamin D and COVID-19 infection.

The main focus of the chapter is to study the diffusion of blockchain technology. Under the theoretical framework of innovation diffusion theory (IDT) analyses were conducted with the aim to localize blockchain technology in the adoption decision process and in the adoption curve. Thus, innovators and adopters of blockchain in different economic activities such as finance and banking, manufacturing, healthcare, education, and agriculture were presented. The purpose is to identify what economic sectors are reaping benefits from blockchain technology and what sectors are yet far away from its adoption. Furthermore, advantages of blockchain technology were also addressed because they are able to influence and accelerate its adoption. Insights are particularly relevant for future adopters and policy makers to enhance emergent technology adoption and reach economic benefits in the digitalization era.
Blockchain and Governance Structure
Authors: Srivastava Rohan , Selvanambi Ramani
Published: June 2023

The rapid growth in the advancement of blockchain technology and its development has brought its usage in every field. Traditional legal frameworks, which depend on establishing central points of accountability and responsibility, have difficulties as a result of the characteristics of blockchain, such as decentralisation, transparency, integrity, and immutability, among others. A key challenge behind the adoption of blockchain is understanding the dynamics of blockchain governance. With the promise of an efficient network owing to the elimination of intermediaries, governance in blockchain may be understood as addition of standards and culture, laws and codes, people, and institutions that promote coordination and jointly decide a particular organisation. As a result, having a headquarters is not necessary; instead, development can rely on a globally dispersed network of programmers who create the software protocol, giving rise to the idea of a DAO (decentralized autonomous system).

Published: June 2023

Microwave absorber is commonly used in defense, electromagnetic compatibility (EMC)/electromagnetic interference (EMI) reduction and anechoic chamber application. Conventional electromagnetic (EM) absorbers have some constraints in practical handling due to its heavy weight. In this paper, the research focuses on the development of high performance and lightweight microwave absorber. A lightweight and simple design configuration of different rectangular slot size array implemented on hollow pyramidal microwave absorber are carried out. There are two different designs of different slot size array calculated based on 3GHz, 6GHz and 9GHz frequency slot size. The two designs have an opposite slots size array arrangement namely different slot size 3GHz, 6GHz, 9GHz order design array and different slot size 9GHz, 6GHz, 3GHz order design array. The absorption is measured using the Naval Research Laboratory (NRL) arch free space method in the frequency range of 1GHz to 12GHz covering L, S, C and X band. In the measurement result, the maximum absorption performance is obtained by the different slot size 9GHz, 6GHz, 3GHz order design array which is up to -44.23dB at X-band. The measurement results for both designs array show good absorption performance which exhibit below than -20dB especially at high frequency band. The proposed designs have been identified as the new approach to increase absorption improvement over a broad frequency range application.

Published: June 2023

Materials with high dielectric properties have become interested due to their important applications, mainly in electronics and energy storage. This study assesses the dielectric properties of epoxy composites containing silver nanoparticles (AgNPs) and carbon nanotube (CNT) composite materials. These samples' permittivity and reflective properties were measured using Vector Network Analyser (VNA) within the X-band frequency (8.2 – 12.4 GHz). Samples were prepared at various loading (0.1-5 wt.%), with various thickness of (0.5, 1.0, 1.5 and 2.0 mm). Regardless of the fillers loading and sample thickness, it was found that the values of real permittivity, er', remain constant along the frequency range. At the same sample thickness, it was found that the values of both er' and er'' increase as loading increases, indicating the function of AgNPs and CNT in enhancing the dielectric and electrical conductivity properties of epoxy composites, respectively. The highest value of er' is recorded as 5 F/m (at f = 8.2 GHz), measured at 5 wt.% loadings and 0.5 mm sample thickness. Measurement on S11 parameters at f = 8.2 GHz indicated that the SER values are between 9 dB and 15 dB, with no obvious pattern observed, regardless of the fillers loading and sample thickness. This study highlights the dielectric properties improvement of epoxy composites by incorporating dual fillers.

The formation of ohmic contacts by laser annealing approach is of great importance for SiC power devices, since it allows their fabrication on thin substrates, that is of crucial significance to reduce power dissipation. Ni silicide reaction under UV laser irradiation has been studied in detail with particular focus on single pulse approach, in order to describe the early stage of reaction process. The use of a multi pulse approach, for the formation of Ni silicide-based ohmic contacts by means of excimer laser annealing, has been investigated in this work. The reaction process has been characterized, as a function of number of pulses, by means of X-Ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) analysis. Laser process simulations, formulated in the framework of phase field theory, have been performed in order to predict the evolution of material during reaction under annealing. Simulations show that reaction moves to Si-reach phases with the increasing on pulses, with a co-existence of Ni2Si and Ni3Si2 phases for the three pulses process. Moreover, simulations show critical differences, in terms of the uniformity of the distribution of the silicide phases along the film, between the single pulse and the multi pulses cases and the increasing of thickness of silicide phases with the pulse sequence. These predictions are in good agreement with the findings of XRD and TEM analyses. The electrical properties of the reacted layer have been evaluated on Schottky Barrier Diodes (SBD) devices, confirming the ohmic behaviour of multi pulse annealed samples.

Published: June 2023

Mechanisms to shorten the duration of tuberculosis (TB) treatment include new drug formulations or schedules and the development of host-directed therapies (HDTs) that better enable the host immune system to eliminate Mycobacterium tuberculosis. Previous studies have shown that pyrazinamide, a first-line antibiotic, can also modulate immune function, making it an attractive target for combinatorial HDT/antibiotic therapy, with the goal to accelerate clearance of M. tuberculosis. In this study, we assessed the value of anti–IL-10R1 as an HDT along with pyrazinamide and show that short-term anti–IL-10R1 blockade during pyrazinamide treatment enhanced the antimycobacterial efficacy of pyrazinamide, resulting in faster clearance of M. tuberculosis in mice. Furthermore, 45 d of pyrazinamide treatment in a functionally IL-10–deficient environment resulted in sterilizing clearance of M. tuberculosis. Our data suggest that short-term IL-10 blockade with standard TB drugs has the potential to improve clinical outcome by reducing the treatment duration.

Published: June 2023

Bullous pemphigoid (BP) is an autoimmune disease with a chronic relapsing course, predominantly affecting elderly people. Drugs are one of the possible triggers. A class of antidiabetic drugs often associated with the development of BP are inhibitors of dipeptidyl peptidase 4 (DPP-4 inhibitors or gliptins), while less known is the association with glucagon-like-peptide-1 (GLP-1) receptor agonists. We describe a case of BP caused by dulaglutide and summarize the other few cases described in the literature. As a class of drugs widely used in clinical practice, it is important to know about this possible adverse event.
Ecology and distribution of the European Roller Coracias garrulus in a recently recolonized area of Northern Italy
Authors: Ghiggi Alessandro
Published: June 2023

This study reports the first data on the ecology and distribution patterns of a population of Eurasian Roller Coracias garrulus breeding in the province of Alessandria in northwestern Italy. The research was conducted between 2017 and 2021. 13 pairs were found, 12 of which were confirmed to be breeding. The species primarily chose to nest in natural cavities in White poplar Populus alba, with nesting observed to a lesser extent in Black poplar Populus nigra, Turkey Oak Quercus cerris and in one case sandy river banks. The home range of each pair is mostly within pluriannual stable meadows and arable crops; on average it extends over 0,92 km2 with values that seems to oscillate according to the degree of fragmentation and isolation of patches of stable meadows: this can be explained by the lower availability of arthropods (consisting mostly of Orthoptera) found in mosaics of alternating meadows interspersed with annual crops. In such conditions, a low density of pairs was observed, along with an increase in territorial boundaries and greater distance between the nests. In the sectors characterised by large, multi-annual stable meadows, with more diverse and abundant entomofauna, supporting a higher number of breeding pairs, a significant contraction of home ranges is observed, with an increased concentration of nesting sites, and higher intraspecific tolerance. Between 2019 and 2021 a total of 17 artificial nest boxes were installed, 3 of which have been successfully occupied. Given the continuous anthropogenic transformation these territories are regularly facing, sometimes subtracting potential nesting or feeding sites due to crop rotation, coppicing, ex-novo construction of ground solar panel systems on agricultural land, etc., in order to protect and conserve this population of European Roller, it is desirable to put in place a greater number of artificial nest structures together with monitoring aimed at protecting the biodiversity of the territory.

Published: June 2023

In this article, the question of the natural-ecological standard of bees is highlighted, and practical ways of preserving life indicators of the biosphere are shown on its example. Also, in the article, it is proved through examples that the material foundation of the world order, green economy, lies in the ecological standards of the existence of nature. Currently, there are about 8 billion people living in the world. More than 1.1 billion of this population live in an ecologically dangerous environment. Today, one-third of the world’s population lacks clean drinking water. As long as humanity does not comply with the standards and laws of nature in terms of its behavior, labor activities, and impact on nature, it is not a question that it will become not only nature, the environment, but even itself. In order for humanity to live a healthy life on planet Earth, the ozone layer in the biosphere should not decrease below its natural-ecological norm of 300 Dobson units, clean water should not lose its quality indicators, the amount of carbon dioxide in the air should not exceed 0.003%, the biological productivity of water ecosystems should not decrease, the limitric indicators of the soil, ecological values of ecological components should be preserved, pollution and man-made pressures should be reduced.

THE POSITION AND TRANSFORMATION OF THE PUBLIC SPHERE IN THE INTERNET ENVIRONMENT
Authors: Ratković Stefan
Published: June 2023

Contemporary media theories increasingly encounter intense changes in social relations that are the result of changes in communication techniques and means. McLuhan called this dynamic a media-centric driver of social change. Media theories and communication disciplines are becoming more current because they have a historical opportunity to follow (post)modern society, which is in a state of constant change mediated by digital technologies. The aim of this paper is to examine whether communication and organizing people through social networks can lead to the transformation of the public sphere as defined by Habermas and related authors. We will build on Habermas’ categorization of historical transformations of the public sphere in order to understand the context and epoch of the current transformation. The second hypothetical question of the paper is whether the Internet could replace some social institutions and question the authorities and conventions achieved, especially if we pay attention to the criticism of democracy by authors like Colin Crouch (2018: 9) who questions the legitimacy of current democratic elections concluding that “people are not offered essential possibility to participate in political processes”. Finally, the question remains whether the Internet as a mass medium has a systemictechnocratic character of maintaining the status quo or whether it can serve as a driver of change or a means of direct democracy for users. We believe that this kind of work will be a nice link or a quality overview of theories and anticipations concerning the issue of political and electoral motivation - the topic with which Columbia University’s major research on media effects began.
Dying Properties of Natural Dyes Extracted from Parkia biglobosa Tree Bark on Cotton Fabric
Authors: E.B Olua , A.O Oforghor , C.N Shailong
Published: June 2023

The research work was carried out to extract natural dyes from Parkia biglobosa tree bark. Synthetic dyes are toxic, non-biodegradable and not friendly to the environment i.e. non-eco-friendly. Natural dye therefore perfectly fit into this since they are non-toxic, biodegradable, non-hazardous and more eco-friendly. Natural dye was extracted from Parkia biglobosa tree bark using Soxhlet extraction method and the dye extract was applied on cotton fabric. The percentage exhaustion, fastness properties and effect of mordant on the dyed samples was evaluated. The post-mordanting method was used to apply the mordant (potassium dichromate) on the samples. The dyeing of the samples were carried out based on the dyeing parameters such as dye concentration, electrolyte concentration, time and temperature respectively. From the result obtained, it was observed that the percentage exhaustion–quantity of dye absorbed by cotton fibre decreases with increase dye concentration. Similarly the absorption of dye was increased with the decrease of dye concentration. The highest percentage exhaustion of 96% was obtained at 10% dye concentration. However, it is observed, that increase in electrolyte concentration resulted increase in the percentage exhaustion. The highest percentage exhaustion of 61% was obtained at 10% electrolyte concentration. This observation is in agreement with the effect of electrolyte concentration on percentage exhaustion. From the result obtained, it was observed that the percentage exhaustion–quantity of dye absorbed by cotton fibre increases with increase in time of dyeing. The highest percentage exhaustion of 76% was obtained at 100 minutes dyeing time. It is obvious, from Figure 4 that the rate of dyeing increases gradually by raising the temperature. The highest dye exhaustion was attained at boiling (100oC). It may be suggested that the extracted dye in the aqueous medium is in aggregated form since they need an increase temperature to migrate into the fibre. In the effect of mordant on dye uptake and enhancement of fastness properties was evaluated from the result; it was observed that mordanting have improvement on the fastness properties. Comparing with the sample without mordant, post-mordanting have a better fastness property. However, on the whole, the mordant sample performs better. From the results it can recommended that dye extracted from Parkia biglobosa Tree Bark can be used to dye cotton fabric. The post-mordanted treated fabric samples have improved fastness properties when compared with non-mordanted fabric samples. The mordant also changed the shade of the dyed samples.

ANALYSIS OF THE EFFECT OF DOWN TIME ON PRODUCTIVITY AT PT. EASTERN PEARL FLOUR MILLS MAKASSAR
Authors: Ahmad Ilham , Saleh Rahmawati , Rahmaniar Rahmaniar
Published: June 2023

Productivity is a comparison between the results achieved (output) with the overall required resources (input) or a comparison between the results achieved with the role of labor per unit time.

The purpose of this study was to study Down Time analysis techniques for productivity in a wheat processing company (PT. Eastern Pearl Flour Mills Makassar), which produces wheat flour products of the Gatotkaca, Gunung, Kompas and Gerbang types. Down Time is the amount of time when a tool/machine cannot operate due to failure, but the factory can still operate because there are still other tools/machines that can replace functions so that the production process can still run.

Based on the data analysis of the calculation of down time for manpower, it shows that the existence of down time during the process will affect the level of productivity (actual and standard). The value of down time from the calculation of working hours minus work effectiveness results in down time for each production area each month. The manpower down time results from all areas, namely in the area of 0 minutes/month. While the amount of data from the analysis of down time calculations for machines in all areas has a higher number of machine down times, namely in the milling area of 28 hours. And for the lowest results, namely in the area of unloading, cleaning, and packing, it is 0 hours.

Simplified and Improved LSB2 (SILSB2) Method of Secret Message Steganography
Authors: Alqadi Ziad
Published: June 2023

A simplified and improved method based on LSB2 (SILSB2) method of secret message steganography will be introduced. The method will simplify the message hiding and extracting functions by reducing the set of operations used to hide and extract the secret message. The proposed method will work on inserting and retrieving the secret message in one go instead of inserting or retrieving it byte by byte as used in the classical methods. The introduced method will add a security issues to LSB2 method by using a special private key. This key will be used to divide the secret message into blocks, and each block will be hidden/extracted alone. The private key will be used also to define the staring locations in the covering-stego images, where to start hiding or extracting the message block. The private key will provide a good key space to protect the message from being hacked, the extracted message will be very sensitive to the private key values, any changes in these values will lead to extract a corrupted damaged message, and these changes will be considered as a hacking attempt. The introduced method will be tested and implemented using various messages and various covering images, the obtained results will be analyzed to prove the quality, security, sensitivity and the efficiency provided by the proposed method.
