Matching Game based Task Offloading and Resource Allocation Algorithm for Satellite Edge Computing Networks

Aiming at the problem of computing offloading with resource constraints in edge computing of dual-layer satellite networks, each low earth orbit (LEO) satellite can offload computing workloads to Geostationary Orbit (GEO) satellites. In order to obtain the optimal strategy for radio resource allocation and offloading decision-making, the system overhead minimization problem is studied, and the offloading decision problem is modeled as a two-sided matching game problem with LEO satellites and GEO satellites as participants. The solution of the offloading decision is given by an improved two-sided many-to-one matching game algorithm with a preference for delay and energy cost. Simulation results show that by effectively offloading decision-making and power, bandwidth, and computing resource allocation, the proposed algorithm can achieve remarkable performance in satellite network edge computing. Meanwhile, compared with the existing methods, the proposed offloading algorithm can effectively reduce the running time of the offloading decision algorithm by 55.53% while the system overhead is reduced by 8.8%.
A Write-Buffer Scheme to Protect Cache Memories Against Multiple-Bit Errors

Protecting cache memories against radiation-induced soft errors is critical in designing highly reliable processors. Dirty lines in write-back data caches are more critical, since the dirty lines have no backups in lower-level memory (LLM). This paper provides a write-buffer scheme for backing up dirty lines to protect cache memories based on the replication mechanism combined with interleaving parity check against multiple-bit errors. The write-buffer contains two same replication caches to replicate the dirty data from the original cache, and the two replication caches take turns to write the replicated data back to LLM during the free time when there is no access in LLM. In this way, the dirty data in original cache is backed up to LLM that can be used for error recovery, and meanwhile, spaces of the replication caches are released to replicate new dirty data; moreover, the writebacks of the replicated data can be performed in the background without extra clocks. Simulation results show that the proposed write-buffer scheme can provide a full protection for caches without degrading system performance, while it can improve the system performance by an average of 1.4% due to the background writebacks, and compared with state-of-the-art replication-based technique, it can increase the replication capability by 11.6% and save 6.2% energy consumption in case of the optimal configuration. It is superior to the existing techniques in terms of protection capability and system performance overhead.
Antibacterial, Antibiofilm, and Antioxidant Activity of 15 Different Plant-Based Natural Compounds in Comparison with Ciprofloxacin and Gentamicin

Plant-based natural compounds (PBCs) are comparatively explored in this study to identify the most effective and safe antibacterial agent/s against six World Health Organization concern pathogens. Based on a contained systematic review, 11 of the most potent PBCs as antibacterial agents are included in this study. The antibacterial and antibiofilm efficacy of the included PBCs are compared with each other as well as common antibiotics (ciprofloxacin and gentamicin). The whole plants of two different strains of Cannabis sativa are extracted to compare the results with sourced ultrapure components. Out of 15 PBCs, tetrahydrocannabinol, cannabidiol, cinnamaldehyde, and carvacrol show promising antibacterial and antibiofilm efficacy. The most common antibacterial mechanisms are explored, and all of our selected PBCs utilize the same pathway for their antibacterial effects. They mostly target the bacterial cell membrane in the initial step rather than the other mechanisms. Reactive oxygen species production and targeting [Fe-S] centres in the respiratory enzymes are not found to be significant, which could be part of the explanation as to why they are not toxic to eukaryotic cells. Toxicity and antioxidant tests show that they are not only nontoxic but also have antioxidant properties in Caenorhabditis elegans as an animal model.
Microbial Fertilization Improves Soil Health When Compared to Chemical Fumigation in Sweet Lily

Lanzhou Lily(Lilium davidii) var. unicolor, which is also known as sweet lily in China, is used as a type of food. This lily is distributed in narrow regions, propagates asexually, cultivates perennially, and cultivates commonly in serious consecutive replant problems (CRPs). Soil fumigation is commonly used to control soil-borne disease to alleviate crops’ consecutive replant problems (CRPs). However, due to the improper fumigation application, it is common to cause chemical hazard to crops. In this study, we designed a two-factor experiment to explore the bacterial and fungal community structure and some specific microbial groups in the lily rhizosphere soil after chemical versus bacterial fertilizer treatments, by using a metagenomic analysis of the treated soils. The results showed that metham-sodium soil fumigation (SMF treatment) significantly decreased plant growth, as well as it significantly decreased both soil fungal diversity and abundance at the OTUs levels, while Special 8™ microbial fertilizer supplement (MF treatment) significantly improved plant growth and increased fungal diversity and abundance. Under FM treatment, Chao1 richness and Shannon’s diversity increased by 6.70% and 35.09% compared to CK (no treatment). However, the bacterial diversity and abundance were not significantly changed among these treatments. The fungal and bacterial community structure were different in all treatments. In SMF treatment, the pathogenic fungal species Fusarium oxysporum increased compared to CK, but it significantly decreased in MF treatment; in MF and MMF treatments, some beneficial bacteria groups such as the bacterial phylum Proteobacteria and its member genus Sphingomonas, as well as the fungal genus Mortierella, increased compared to CK and SFM treatments, but the harmful bacterial genera Gemmatimona was decreased, as well as the harmful fungal genus Cryptococcus. Thus, we concluded that under chemical fumigation conditions, both fungal diversity loss and overall microorganism reduction, which impair multiple ecosystem function, in conjunction with the increase of harmful fungal species such as Fusarium oxysporum, are causes for soil degradation. On the other hand, under microbial fertilizer supplement, it was the fungal diversity increase, as well as these beneficial microorganisms groups’ accumulation, together with those harmful groups’ depletion, played important roles in restoring and improving soil health that suffered from the chemical fumigant hazard. In addition, the bacterial phylum Proteobacteria and its member genus Sphingomonas are involved in soil health recovery and promotion. The results also emphasized that whether soil is chemically fumigated or not, beneficial microorganism supplementary is effective in ensuring soil productivity.
Adaptation and Testing of the Factorial Structure of the Physical Education Grit Scale for Use in Secondary Education in Spain

The challenges faced by students during Physical Education classes embrace both physical and academic aspects. Therefore, each individual possesses a series of internal psychological mechanisms, such as Grit, which allow them to adapt and overcome the vicissitudes. However, there are no scales that assess Grit in Span. Thus, the aim of the present study is to test the factor structure of the Physical Education Grit Scale in Span of Physical Education classes. For this purpose, 857 secondary school students took part in the present study. In order to test the factor structure, a confirmatory factor analysis, an exploratory factor analysis, an analysis of the reliability of the questionnaire and an analysis of temporal stability were carried out. The results showed that the factor structure consisted of two factors and four sub-factors (χ2/df = 2.17 (p = 0.001); CFI = 0.96; TLI = 0.96; IFI = 0.96; RMSEA = 0.051; SRMR = 0.037). In addition, the reliability and temporal stability analyses showed acceptable indices. Based on these results, evidence of reliability and validity of the Physical Education Grit Scale in Span of Physical Education is provided.

Structure Design and Reliability Evaluation of the Elasto-Optical Sensor for the Space Charge Ellipsometry Detection Method

To support the development of the space charge ellipsometry detection method, this article focuses on the elasto-optical sensor as the core of the measurement system. Oriented to low elastic modulus and high thermomechanical stability, the modification method of SU-8 photoresist as the sensor material was proposed. The molecular dynamics simulation pointed out that the SU-8 system with 70% cross-linking degree showed higher thermomechanical stability, and the average elastic modulus was 3.7459 GPa with a mean square error of 0.1669. Then, the refractive index response of different structure sensors under picosecond elastic waves was evaluated based on the finite-element simulation. It was indicated that, compared to the applied elastic wave, the square and circular structure sensors showed measurement distortion and delay, while the hexagon structure sensor benefited from the superior mechanical stability, which could achieve the real-time response. Furthermore, the sensor was prepared based on the photolithography principle, and the ellipsometry measurement platform was constructed to carry out the experimental selection and reliability evaluation of the sensor. It was found that, compared with the square and circular structure, the hexagon structure sensor could achieve the measurements of elastic waves with kilohertz repetition and femtosecond pulsewidth. In contrast to the pulsed electro-acoustic (PEA) piezoelectric sensing module, the measurement signal of hexagon structure sensor was at the same millivolt level, while the measurement waveform was smoother and less distorted.
Measurement of Hand-Arm Vibration Syndrome of an Agricultural Tractor Steering Wheel using Machine Vision System

: The structure of an agricultural tractor is a structure without a suspension system to limit the vibrations generated by its engine. It exposed the entire body of an agricultural tractor operator to vibration. Thus, the body of the driver, constantly exposed to the vibration, becomes fatigued. This fatigue becomes a factor in the driver's inattention. The driver’s body has transmitted to vibration through the tractor's seat, accelerator pedal, brake pedal, and steering wheel. Quantifying seat, accelerator pedal, brake pedal, and steering wheel vibrations is one of the most important factors in determining the cause of vibration and correcting it. The ISO 5349 standard lays down a guideline for the measurement and assessment of vibrations transmitted by the human hand. To meet the ISO 5349 standard, assess human exposure to hand-transmitted vibration and meet the human subjective comfort level. It must keep the vibration within a specified range. This study attempts to measure steering wheel vibrations through a new machine vision system using up-sampled cross correlation and a Discrete Finite Transform algorithm. In this study, it was impossible to calculate vibration in three axes from the video images recorded by the camera. According to ISO 5349-2, the vibration obtained on two axes multiplied by 1 to 1.7 to calculate the equivalent measurement for the vibration on the third axis. The results show that when the vibration is high; the errors are less and when the vibration is low, near zero, the errors range from 30 % to 50 %. But this study suggests that very low-level vibrations are unnecessary for vibration analysis. This study is not suitable for Nano-vibration measurement methods that Paved, and test. The analyzer analysed I-kaz Vibro analyse and data dispersion HAV levels. HAV analysed using I-Kaz Vibro coefficient (Zv), display, and daily exposure (8). scattering on I-Kaz Vibro displays Zv and A(8) are rising. Model and Zv predicted HAV exposure. model: Zv with vehicle speed

A New Image Steganography Technique

A new image steganography technique is proposed by employing block matching process. The subject secret image which needs to be transmitted, without noticing its existence, is vector-quantized using a lookup vector-table which is directly formed from another image called the host (key) image. The address vector which contains the addresses of the chosen vectors of the lookup table can then be reordered in secret permutation resulting in a permuted address vector (PAV). This secret permutation (SP) is the secret key for the imagesteganography process. During this proposed steganography process, nothing is embedded in the key image which could be any image. The proposed scheme can be applied in spatial domain as well as in the approximation subband image of one level discrete wavelet transformdecomposition in order to achieve both much smaller lookup table size and less processing time. The simulation of the proposed imagesteganography technique shows that the extracted subject secret image has good quality even after common signal processing operations on the key image. Moreover, the key image can be as small as one fourth of the subject secret image and high acceptable quality of extracted secret image can still be obtained. Keywords: Image steganography, Block matching, Vector quantization, Secret permutation, Discrete wavelet transform and information confidentiality.
Development and Practical Application of Glucose Biosensor Based on Dendritic Gold Nanostructures Modified by Conducting Polymers

In this study, graphite rod (GR) electrodes were electrochemically modified by dendritic gold nanostructures (DGNs) followed by immobilization of glucose oxidase (GOx) in the presence of mediator phenazine methosulfate (PMS). Modified with polyaniline (PANI) or polypyrrole (Ppy), GOx/DGNs/GR electrodes were used in glucose biosensor design. Different electrochemical methods were applied for the registration of glucose concentration, and constant potential amperometry (CPA) was chosen as the best one. PANI and Ppy layers synthesized enzymatically on the GOx/DGNs/GR electrodes extended the linear glucose determination range, the width of which depended on the duration of PANI- and Ppy-layers formation. Enzymatically formed polypyrrole was determined as the most suitable polymer for the modification and formation of the glucose biosensor instead of polyaniline, because it was 1.35 times more sensitive and had a 2.57 times lower limit of detection (LOD). The developed glucose biosensor based on the Ppy/GOx/DGNs/GR electrode was characterized by appropriate sensitivity (59.4 μA mM−1 cm−2), low LOD (0.070 mmol L−1), wide linear glucose determination range (up to 19.9 mmol L−1), good repeatability (8.01%), and appropriate storage stability (33 days). The performance of the developed glucose biosensor was tested in biological samples and beverages.
EFFECT OF THE ILEAL BRAKE ON SATIETY AND PROXIMAL GASTRIC FUNCTION: IS IT PEPTIDE YY?

Recent studies indicate that peptide YY (PYY) influences satiety, but the role of PYY as a physiological regulator of satiety is under debate. This study was designed to compare the effects of ileal brake activation through ileal fat perfusion (endogenous PYY) versus exogenous PYY infusion on satiety and proximal gastric motor function. Two protocols were performed in both fasting and postprandial states. Protocol 1: ileal fat perfusion versus saline (control). Protocol 2: intravenous PYY 3-36 infusion at low and high doses of 15 and 30 pM/kg/hr vs. placebo. Plasma PYY (RIA), satiety scores and proximal gastric motility (barostat) were measured. Results: Ileal fat significantly (p<0.05) increased plasma PYY from 15 ± 1 to 26 ± 2 pM. During PYY infusion plasma levels of 28 ± 3 pM (low dose) and 55 ± 10 pM (high dose) were reached. Both in the fasting and postprandial state ileal fat induced satiety (p<0.05) in contrast to PYY 3-36 . Fasting gastric volume (barostat) increased significantly (p<0.01) in response to ileal fat (from 150 ± 14 ml to 433 ± 54 ml) but not in response to PYY 3-36 infusion. In all experiments meal ingestion resulted in identical increments in proximal gastric volume. Only ileal fat, not PYY 3-36 significantly (p (cid:2) 0.01) enhanced postprandial gastric relaxation. Conclusions: Ileal fat induces satiety and results in proximal gastric relaxation, in contrast to exogenous PYY 3-36 at identical plasma levels. These data do not support a role for PYY as a physiological mediator in ileal brake induced satiety or ileal brake induced proximal gastric relaxation.
The Relationship between Selected Inflammation and Oxidative Stress Biomarkers and Carotid Intima-Media Thickness (IMT) Value in Youth with Type 1 Diabetes Co-Existing with Early Microvascular Complications

Recent years have confirmed the importance of oxidative stress and biomarkers of inflammation in estimating the risk of cardiovascular disease (CVD) and explaining not fully understood pathogenesis of diabetic macroangiopathy. We aimed to analyze the relation between the intima-media thickness (IMT) of common carotid arteries and the occurrence of classical cardiovascular risk factors, together with the newly proposed biomarkers of CVD risk (high-sensitivity C-reactive protein (hsCRP), myeloperoxidase (MPO), adiponectin, N-terminal-pro B-type natriuretic peptide (NT-proBNP) and vitamin D) in youth with type 1 diabetes (T1D) recognized in screening tests to present early stages of microvascular complications (VC). The study group consisted of 50 adolescents and young adults with T1D, mean age 17.1 years (10–26 age range), including 20 patients with VC (+) and 30 VC (−). The control group (Control) consisted of 22 healthy volunteers, mean age 16.5 years (11–26 age range). In the VC (+) patients, we found a significantly higher concentration of HbA1c, lipid levels, hsCRP and NT-proBNP. BMI and blood pressure values were highest in the VC (+) group. Higher levels of MPO and lower levels of vitamin D were found in both diabetic groups vs. Control. IMT in VC (+) patients was significantly higher and correlated positively with HbA1c, hsCRP, NT-pro-BNP and negatively with vitamin D levels. In conclusion, youth with T1D and VC (+) present many abnormalities in the classical and new CVD biomarkers. hsCRP and MPO seem to be the most important markers for estimating the risk of macroangiopathy. NT-proBNP may present a possible marker of early myocardial injury in this population.
Causality Analysis for COVID-19 among Countries Using Effective Transfer Entropy

In this study, causalities of COVID-19 across a group of seventy countries are analyzed with effective transfer entropy. To reveal the causalities, a weighted directed network is constructed. In this network, the weights of the links reveal the strength of the causality which is obtained by calculating effective transfer entropies. Transfer entropy has some advantages over other causality evaluation methods. Firstly, transfer entropy can quantify the strength of the causality and secondly it can detect nonlinear causal relationships. After the construction of the causality network, it is analyzed with well-known network analysis methods such as eigenvector centrality, PageRank, and community detection. Eigenvector centrality and PageRank metrics reveal the importance and the centrality of each node country in the network. In community detection, node countries in the network are divided into groups such that countries in each group are much more densely connected.
Double Gain: The Radio Frequency Catheter Ablation of Ventricular Aneurysm Related Recurrent Ventricular Tachycardia on a Tremendous Cardiac Outpouching

Dilated cardiomyopathy (DCM) is a classic type of non-ischemic cardiomyopathy. Of these, idiopathic cardiomyopathy (IDCM) is a rare type of non-genetic dilated cardiomyopathy. More specifically, the patient had suspected IDCM combined with sustained polymorphic ventricular tachycardia (PMVT) of left ventricular basal segmental origin, cardiac systolic dysfunction and an ejection fraction (EF) of 29%. He had an abnormally large ventricular aneurysm (VA) in the posterior wall of the left ventricle with left ventricular end diastolic dimension (LVDd) of 90 mm. We performed an endocardial radiofrequency catheter ablation (RFCA) of the patient’s recurrent ventricular tachycardia (VT) on the basis of an implantable cardioverter (ICD). Although minimally invasive RFCA also carries a high risk, it is currently a two-pronged option to improve the patient’s quality of life and to prevent the recurrence of VT. Postoperatively, the patient was routinely given optimal anti-arrhythmic and heart failure (HF) treatments to improve cardiac function as well as being followed up for 9 months. The patient’s EF ascended to 36% without any recurrence of VT. In summary, RFCA of suspected IDCM combined with VA and VT of basal area origin would be an effective treatment.
