DIMDP: A Driving Intention-Based MDP Service Migration Model under MEC/MSCN Architecture

Service migration is one of the key topics of Internet of Vehicles (IoV). MEC (mobile edge computing), which is carried on the roadside unit (RSU), could serve as a service provider and provide a V2I (vehicle to infrastructure) cooperation service. To solve the high migration rate caused by the vehicle’s high mobility feature, MSCN (mobile secondary computing node) framework is defined. To study service migration features under the MSCN framework further, in this paper, road vehicle’s motion features, e.g., driving intention and regional traffic condition, are introduced to construct the Markov decision model, which is used to explain the service migration decision procedure, while DIMDP (driving intention-based MDP) is defined. Corresponding cost functions are defined, while the optimal object is given. A two-way road scenario is selected as a typical scenario. NS3 platform is employed to fulfill the simulation process. Simulation results show that the proposed service migration strategy performs well and is intensive to vehicle density change.
Outage Performance Enhancement for NOMA-Based Cooperative Relay Sharing Networks

This letter considers a non-orthogonal multiple access (NOMA) based cooperative relay sharing (CRS) network, where two sources communicate with their corresponding users over the same time and frequency via a shared decode-and-forward relay. A novel transmission scheme using max-min criterion based dynamic decoding order strategy is proposed to minimize the outage probability of the network at the cost of lower complexity and overhead. The closed-form expression of the overall outage probability for the proposed scheme is derived. Both analytical and simulation results show that the proposed scheme can achieve non-zero diversity order and almost the same outage performance as the dynamic power allocation based transmission scheme for NOMA based CRS networks.
Understanding the perceived psychosocial impact of father absence on adult women

Given South Africa’s social, historical, political, and economic landscape which has contributed towards a relatively high prevalence of father absence, particularly in Black families, and the risk of adverse implications for children’s psychosocial development, the issue of absent fathers is an important area for research. However, the differential impact of father absence on the girl child remains relatively under-researched. Hence, the study explored the perceived psychosocial impact of father absence during childhood and adolescence on adult women. A case study research design located within a qualitative research approach was employed and nine adult women aged 18 to 35 years were purposefully recruited from Grobler Park, Johannesburg West for participation in the study. Due to the COVID-19 pandemic, three participants were interviewed telephonically and seven face-to-face. The research was guided by Mkhize’s sociocultural psychological tradition and Erikson’s psychosocial development theory. Thematic analysis was employed to analyse the collected data. Among the key findings was that the women perceived the experience of father absence to have adversely affected their feelings of belonging and sense of identity, with some participants having suffered emotional and financial challenges. Participants acknowledged a lack of healthy relationships with other men associated with having grown up with an absent father. While most of the women adopted positive coping strategies, a small number resorted to negative coping. There was also recognition of the important roles that social fathers assume in child-rearing. These findings have important implications for promoting positive father-daughter relations.
Optimized separable convolution: Yet another efficient convolution operator

The convolution operation is the most critical component in recent surge of deep learning research. Conventional 2D convolution needs O ( C 2 K 2 ) parameters to represent, where C is the channel size and K is the kernel size. The amount of parameters has become really costly considering that these parameters increased tremendously recently to meet the needs of demanding applications. Among various implementations of the convolution, separable convolution has been proven to be more efﬁcient in reducing the model size. For example, depth separable convolution reduces the complexity to O ( C · ( C + K 2 )) while spatial separable convolution reduces the complexity to O ( C 2 K ) . However, these are considered ad hoc designs which cannot ensure that they can in general achieve optimal separation. In this research, we propose a novel and principled operator called optimized separable convolution by optimal design for the internal number of groups and kernel sizes for general separable convolutions can achieve the complexity of O ( C 32 K ) . When the restriction in the number of separated convolutions can be lifted, an even lower complexity at O ( C · log( CK 2 )) can be achieved. Experimental results demonstrate that the proposed optimized separable convolution is able to achieve an improved performance in terms of accuracy-#Params trade-offs over both conventional, depth-wise, and depth/spatial separable convolutions
Zoonoses and the Aboriginal and Torres Strait Islander population: A One Health scoping review

With limited access to animal health services, and high disease burdens among domesticated animals, Aboriginal and Torres Strait Islander communities in Australia face higher risk of disease including zoonoses. However, we lack understanding of the contribution of often preventable zoonoses to the health of these communities, which would enable us to enhance public health strategies and improve health outcomes. We conducted a scoping review to identify the current state of evidence on zoonoses in the Aboriginal and Torres Strait Islander population. We examined the size, scope and characteristics of the evidence base and analysed the zoonoses detected in the studies within a One Health framework. We identified 18 studies that detected 22 zoonotic pathogens in animals, people, and the environment, with most studies detecting pathogens in a single One Health sector and no studies investigating pathogens in all three sectors. Findings indicate that despite the strong conceptual foundations of One Health throughout the evidence base, evidence is lacking in application of this concept. There is a need to undertake further research that prioritises Aboriginal and Torres Strait Islander leadership, considers the contribution of human, animal and environmental health factors, and investigates the prevalence and impact of zoonoses in communities through a One Health approach.
Probing acceleration and turbulence at relativistic shocks in blazar jets

Diffusive shock acceleration (DSA) at relativistic shocks is widely thought to be an important acceleration mechanism in various astrophysical jet sources, including radio-loud active galactic nuclei such as blazars. Such acceleration can produce the non-thermal particles that emit the broadband continuum radiation that is detected from extragalactic jets. An important recent development for blazar science is the ability of Fermi-LAT spectroscopy to pin down the shape of the distribution of the underlying non-thermal particle population. This paper highlights how multi-wavelength spectra spanning optical to X-ray to gamma-ray bands can be used to probe diffusive acceleration in relativistic, oblique, magnetohydrodynamic (MHD) shocks in blazar jets. Diagnostics on the MHD turbulence near such shocks are obtained using thermal and non-thermal particle distributions resulting from detailed Monte Carlo simulations of DSA. These probes are afforded by the characteristic property that the synchrotron $\nu F_{\nu}$ peak energy does not appear in the gamma-ray band above 100 MeV. We investigate self-consistently the radiative synchrotron and inverse Compton signatures of the simulated particle distributions. Important constraints on the diffusive mean free paths of electrons, and the level of electromagnetic field turbulence are identified for three different case study blazars, Mrk 501, BL Lacertae and AO 0235+164. The X-ray excess of AO 0235+164 in a flare state can be modelled as the signature of bulk Compton scattering of external radiation fields, thereby tightly constraining the energy-dependence of the diffusion coefficient for electrons. The concomitant interpretations that turbulence levels decline with remoteness from jet shocks, and the probable significant role for non-gyroresonant diffusion, are posited.
Prediction of the Behavior of Sunflower Husk Ash after Its Processing by Various Torrefaction Methods

Biomass can be considered an alternative to coal in the production of heat and electricity. Many types of biomass are waste from agriculture and the food industry. This waste is cheap, readily available, and replenished annually. However, most agricultural and food industry wastes (sugar cane pulp, olive and sunflower oil production wastes, straw, etc.) have ash with a low melting point. This leads to a rapid growth of ash deposits on the heating surfaces of boilers; as a result, the actual efficiency of boilers in which waste from agriculture and the food industry is burned is 45–50%. Known biomass pre-treatment technologies that allow for the fuel characteristics of biowaste. For example, leaching of biowaste in water at a temperature of 80–240 °C makes it possible to drastically reduce the content of alkali metal compounds in the ash, the presence of which reduces the melting point of the ash. However, this biomass pre-treatment technology is complex and requires additional costs for drying the treated biomass. We proposed to use torrefaction for pre-treatment of biomass, which makes it possible to increase the heat of combustion of biomass, increase the hydrophobicity of biomass, and reduce the cost of grinding it. However, we are not aware of studies that have studied the effect of torrefaction on the chemical composition of ash from the point of view of solving the problem of preventing the formation of agglomerates and reducing the growth rate of ash deposits on the convective heating surfaces of boilers. In this paper, the characteristics of sunflower husk subjected to torrefaction in an environment of superheated steam at a temperature of 300 °C and in an environment of gaseous products at a temperature of 250 °C are studied. All experiments were conducted using fluidized bed technology. The resulting biochar has a calorific value of 14.8–23% higher than the initial husk. To assess the behavior of sunflower husk ash, predictive coefficients were calculated. Torrefaction of sunflower husks does not exclude the possibility of slagging of the furnace but reduces the likelihood of slagging by 2.31–7.27 times. According to calculations, the torrefaction of sunflower husks reduces the likelihood of ash deposits on the convective heating surfaces of the boiler by 2.1–12.2 times. According to its fuel characteristics, the husk, after torrefaction in an environment of superheated steam, approaches wood waste, i.e., can be burned separately without additives or mixtures with other fuels with refractory ash.
Appendix: Chapman-Enskog Expansion in the Lattice Boltzmann Method

The Chapman-Enskog expansion was used in the lattice Boltzmann method (LBM) to derive a Navier-Stokes-like equation and a formula was obtained to correlate the LBM model parameters to the kinematic viscosity implicitly implemented in LBM simulations. The obtained correlation formula usually works as long as the model parameters are carefully selected to make the Mach number and Knudsen number small although the validity of Chapman-Enskog expansion that has a formal definition of time derivative without tangible mathematical sense is not recognized by many mathematicians.
Polar ring galaxies in the Galaxy Zoo

We report observations of 16 candidate polar-ring galaxies (PRGs) identified by the Galaxy Zoo project in the Sloan Digital Sky Survey (SDSS) data base. Deep images of five galaxies are available in the SDSS Stripe82 data base, while to reach similar depth we observed the remaining galaxies with the 1.8-m Vatican Advanced Technology Telescope. We derive integrated magnitudes and u − r colours for the host and ring components and show continuum-subtracted Hα+[N II] images for seven objects. We present a basic morphological and environmental analysis of the galaxies and discuss their properties in comparison with other types of early-type galaxies. Follow-up photometric and spectroscopic observations will allow a kinematic confirmation of the nature of these systems and a more detailed analysis of their stellar populations.
Paramedic’s Trust and Compliances during COVID-19 Preparedness and Recovery Time

High trust in government’s capability is the key to public compliance in supporting COVID-19 management. The paramedic is a profession that has received attention during times of pandemics because they are on duty as frontlines with a high risk of transmission. This research analyzed a survey of 328 paramedics living in Jakarta to examine their perceptions of the COVID-19 pandemic, the government's readiness, the picture of their psychological condition, their trust in the government, and their belief in themselves in health services. The survey was conducted one week after WHO declared COVID-19 a pandemic. This descriptive study indicates that most respondents have serious concerns about the transmission of the virus. On the side, they are obliged by an oath of service, which demands that they are always ready to serve. Only 30% believe the government can handle COVID-19. All respondents strongly supported the "lockdown" policy in every public facility. This finding is consistent with interview data after the highest peak of COVID-19 transmission in September 2021.These findings also point that low trust is driven by inconsistent and less convincing communication of political officials. Despite paramedics' risky conditions, they are responsible for working, but paramedics at the forefront of handling COVID-19 patients require support policies such as higher incentives and the safest protective tools.

Differential Influences of Wind-Blown Sand Burial on Bacterial and Fungal Communities Inhabiting Biological Soil Crusts in a Temperate Desert, China

Biological soil crusts (BSCs) are an integration of external photoautotrophs and internal heterotrophic communities. Sand burial is a ubiquitous disturbance that affects the biodiversity and ecological function of BSCs, but little is known about the influence of sand burial on microbial communities in arid sandy deserts. Here, based on a long-term field experiment and utilizing high-throughput sequencing, we assessed the influence of sand burial on bacterial and fungal communities inhabiting two typical successional stages of BSCs (cyanobacterial crusts for early successional stage and mixed crusts for late successional stage) at the three-sand buried depth (0, 0.5, and 10 mm) in the Tengger Desert, Northern China. We found that the diversity, abundance, and composition of the bacterial and fungal communities were all altered by the sand burial treatment. Different indicator taxa were identified in unburied and buried (shallow and deep) BSCs. Changes in soil properties caused by sand burial have been suggested as a possible cause of changes in the bacterial and fungal community composition in BSCs.
Organizational Benefits of Human Resource Management Roles in South African State-owned Enterprises

Human Resource Management practitioners have been criticized for lacking business acumen due to the nature of the personnel management concept. There has been a change in Human Resource Management roles from traditional personnel management to Strategic Human Resource Management which seeks to provide organizational competitiveness. This article aims to provide organizational benefits of Human Resource Management to an organization as a result of the Strategic Human Resource Management concept. The strategic nature of Human Resource Management has been revealed in this article as there is evidence of Human Resource Management's contribution to the business success. This paper is a study carried out in a South African State-owned enterprise to identify organizational benefits acquired from Human Resource Management roles. Qualitative research was used in this study, and interviews were administered to obtain data from Human Resource practitioners and departmental supervisors in a state-owned enterprise. 24 participants were purposively selected to provide data for the study. This study revealed that the Human Resource department provides beneficial activities to the organization such as reduction of employee turnover, employee development, employee wellness, and internal communication. The critical discussion provided in this paper would strengthen the body of knowledge on the role of Human Resource Management in improving organizational effectiveness.
Detection of spinons via spin transport

The existence of deconfined spinons is the defining property of quantum spin liquids. These exotic excitations have a (fractionalized) spin quantum number and no electric charge, and have been proposed to form Fermi surfaces in the recently discovered organic spin liquid candidates. However, direct probes for them are still lacking. Here we propose to experimentally identify the spinons by measuring the spin current flowing through the spin liquid candidate materials, which would be a direct test for the existence of spin-carrying mobile excitations. By the nonequilibrium Green's function technique we evaluate the spin current through the interface between a Mott insulator and a metal under a spin bias, and find that different kinds of Mott insulators, including quantum spin liquids, can be distinguished by different relations between the spin bias and spin current. We also discuss relations to experiments and estimate experimentally relevant parameters.
Dark matter data and quartic self-couplings in Inert Doublet Model

We analyse the thermal evolution of the Universe in the Inert Doublet Model for three viable regions of Dark Matter mass: low, medium and high DM mass. Those three regions exhibit different behaviour in the possible types of evolution. We argue that the quartic self-couplings in IDM are significant parameters for the astrophysical analysis.
Obscuration, environments and host galaxies of active galactic nuclei.

The work contained within this thesis Is made up primarily of two pieces Both address active galactic nuclei And the galaxies that live nearby The obscured fraction of the population Is the topic of one publication And the type-II fraction in the optical regime In chapter four this is the theme I research the vicinity overdensity Around radio galaxies in chapter three, you’ll see I reduce some spectra at redshift one But not all observations in the end got done With the spectra I have I do what I can As if all target observations had actually ran In the end I conclude with results and the theme of research to be done further downstream. The works contained herein addresses two major topics in extragalactic astrophysics, namely the Type-II AGN fraction and the Overdensity-Radio power relation. Quantifying the Type-II AGN fraction has been attempted by many works in many different observational regimes, finding rather contrasting results. Accretion onto supermassive black holes contributes between 5 per cent and 20 per cent of the luminosity of the Universe, and seems to be closely linked to star formation processes. The large uncertainty on this value is due to the illdetermined contribution from obscured accretion, namely the Type-II fraction.
Intelligent Hardness Prediction of Bearing Rings Using Pulsed Eddy Current Testing

Bearings are central components of rotating machinery. Original equipment manufacturers must utilize high-quality bearings for desirable performances and safety of the equipment. Hardness, which is directly linked to product performance and reliability, is, thus, an essential mechanical property of bearings. As a result, it is necessary to evaluate the hardness during the manufacturing process. However, because of the complicated transformation of microstructures during heat treatment, there is no an established noncontact, quick, and affordable method for measuring the hardness of bearings. This article describes a pulsed eddy current testing (PECT)-based novel method utilizing deep learning for reliable nondestructive testing of bearing rings. The continuous wavelet transform (CWT) was used to combine the time-frequency information in the PECT signals, and the deep learning models were trained to predict hardness. In addition, we compared and optimized the network’s performance in feature maps, the number of convolutional kernels, and the learning rate. The results indicate that the developed novel method has an average error of 1.37% and a maximum error of 1.89%, exhibiting good hardness prediction accuracy and stability.
