Shock Waves in 3d Textile Composite Subject to Hypervelocity Impact
Authors: Saboktakin A. 
Published: October 2022

Abstract
In hypervelocity impacts of composite materials, shock initiation and interaction with composite constituents dominate its responses, particularly the formation and features of the debris cloud. A numerical simulation was performed in this paper to investigate the wave propagation mechanism and obtain the wave response using the finite element method in order to estimate the features of the hypervelocity impact into honeycomb composite with stitched facesheets. Wave propagation can be seen when the structure is exposed to shock waves in skins made of three-dimensional stitched composite, according to the modeling results. The consequences of the stitching process on wave propagation are demonstrated, and their interactions with the stitching fibers are explained. The modeling was done in this paper and the corresponding shock wave analysis provides new insight into the processes of the analysis of the shock waves and the beginning of the debris clouds. This research thoroughly examines the behavior of a three-dimensional textile honeycomb composite in terms of wave propagation and predictions on the location of potential damages. This would provide comprehensive information that would facilitate the development of the new honeycomb composite presented herein toward validating the modeling results for hypervelocity impact events.

Authors: BELGACEM Fatima , MOSTEFAI Mohamed , MILOUD Yahia , BELGACEM Aicha 
Published: October 2022

Abstract
In the agricultural and industrial sectors, solar water pumping systems are gaining popularity due to their environmental friendliness and lack of fuel costs. Traditional electric water pumps are frequently unreliable, while diesel pumps have higher fuel costs. This study's primary aim is to present a comparative study between brushless direct current motor (BLDC) and induction motor (IM) in photovoltaic pumping systems (PVPS). The two most common motor types are examined. The suitability of these two motors types in photovoltaic pumping applications is assessed through simulation works. The mathematical models for the PV array, inverter/motors are developped, the controllers are presented. The Fuzzy Logic is implemented to track the maximum power under different irradiance. The effectiveness of the drive system for beginning and DC link voltage changes brought on by changing sun illumination is also investigated in the study. A full simulation model of the suggested PVPS configuration under data climate conditions of autumn and summer day irradiation (2016) is created using MATLAB Simulink. The BLDC with its electronic commutation due to its performances improve the PVPS by providing sufficient water amounts in an appropriate time with high efficiency compared to IM.

Abstract
Activation of the apoptotic pathway has been associated with promoting neuronal cell death in the pathophysiology of Parkinson disease (PD). Nonetheless, the mechanisms by which it may occurs remain unclear. It has been suggested that stress-induced oxidation and potentially apoptosis may play a major role in the progression of PD. Thus, in this study, we aimed to investigate the effect of subchronic restraint stress on striatal dopaminergic activity, iron, p53, caspase-3, and plasmatic acetylcholinesterase (AChE) levels in an animal model of PD induced by administration of 6-hydroxydopamine(6-OHDA) in the medial forebrain bundle (MFB). The obtained results showed that restraint stress exacerbates motor coordination deficits and anxiety in animals treated with 6-OHDA in comparison to animals receiving saline, and it had no effect on object recognition memory. On another hand, 6-OHDA decreased dopamine(DA) levels, increased iron accumulation, and induced overexpression of the pro-apoptotic factors caspase-3, p53, and AChE. More interestingly, post-lesion restraint stress exacerbated the expression of caspase-3 and AChE without affecting p53 expression. These findings suggest that subchronic stress may accentuate apoptosis and may contribute to DA neuronal loss in the striatal regions and possibly exacerbate the progression of PD.

Microencapsulation of juniper and black pepper essential oil using the coacervation method and its properties after freeze-drying
Authors: Napiórkowska Alicja , Kurek Marcin Andrzej 
Published: October 2022

Abstract
Essential oils are a mixture of chemical compounds very susceptible to the effects of the external environment. Hence, more attention is drawn to their preservation methods. The aim of the study was to test the possibility of using complex coacervation for the microencapsulation of essential oils. Black pepper (Piper nigrum) and juniper (Juniperus communis) essential oils dissolved in grape seed (GSO) and soybean (SBO) oil formed the core material, while gelatin (G) and gum Arabic (GA) formed the wall materials. Various mixing ratios of polymers were tested: 1:1; 1:2, and 2:1. The oil content was 10%, and the essential oil content was 1%. The prepared coacervates were lyophilized and then screened to obtain a powder. For all samples, among others, the following were determined: encapsulation efficiency (EE), Carr Index (CI), Hausner Ratio (HR), solubility, hygroscopicity, moisture content, and particle size. The highest encapsulation efficiency achieved was within the range of 64.09–59.89%. The mixing ratio G/GA = 2:1 allowed to obtain powders that were characterized by the lowest solubility (6.55–11.20%). The smallest particle sizes, that did not exceed 6 µm, characterized the powders obtained by mixing G/GA = 1:1. All powder samples were characterized by high cohesiveness and thus poor or very poor flow (CI = 30.58–50.27, HR = 1.45–2.01).
The climate niche of the invasive tick species Hyalomma marginatum and Hyalomma rufipes (Ixodidae) with recommendations for modeling exercises
Authors: Estrada-Peña Agustín 
Published: October 2022

Abstract
The finding of immature stages of some Hyalomma spp. feeding on migratory birds in Europe is unexceptional. The reports of adults of Hyalomma in Europe and British Isles after successful molting from immatures have sharply increased in recent years. The warming of the target territory could favor the persistence of populations of these invasive ticks. While evaluations of the impact on health or measures of adaptation are on their way, the climate niches of these species remain undefined, preventing preventive policies. This study delineates such niche for both Hyalomma marginatum (2,729 collection points) and Hyalomma rufipes (2,573 collections) in its distribution area, together with 11,669 points in Europe where Hyalomma spp. is considered to be absent in field surveys. Niche is defined from daily data of temperature, evapotranspiration, soil humidity and air saturation deficit (years 1970–2006). A set of 8 variables (annual/seasonal accumulated temperature and vapor deficit) has the maximum discriminatory power separating the niches of both Hyalomma and the negative dataset, with an accuracy near 100%. The use of accumulated annual temperature as the only variable for predictive purposes is unreliable, as far as values of water in air are excluded.
Auto-correlation functions for unitary groups
Authors: LEE KYU HWAN , Oh Se-jin 
Published: October 2022

Abstract
We compute the auto-correlations functions of order m ≥ 1 for the characteristic polynomials of random matrices from certain subgroups of the unitary groups U(2) and U(3) by establishing new branching rules. These subgroups can be understood as certain analogues of Sato-Tate groups of USp(4) in our previous paper. Our computation yields symmetric polynomial identities with m-variables involving irreducible characters of U(m) for all m ≥ 1 in an explicit, uniform way.
Comparison of linewidth narrowing in quantum-dot and quantum-well
integrated III-V/SiN lasers
Authors: Wan Yating , Chow Weng , Alkhazraji Emad , Madaras Scott , Gehl Michael , Skogen Erik , Grillot Frederic , Bowers John 
Published: October 2022

Abstract
This paper describes an analysis of integrated III-V/SiN lasers operating with quantum-dot and quantum-well active regions. We focus on the effects of 0- and 2-dimensional carrier densities of states on linewidth narrowing. The theoretical approach includes a) multimode laser interaction to treat mode competition and wave mixing, b) quantum-optical contributions from spontaneous emission and c) composite laser/free-space eigenmodes to describe outcoupling and coupling among components within an extended cavity. The approach is able to describe the progression to Hz-level lasing linewidth observed in III-V/SiN lasers with quantum-dot active regions. In addition, it predicts that the integration of III-V/SiN mitigates the high quantum-well linewidth enhancement factor, resulting in similar Hz-level linewidth performance. Tradeoffs are explored among linewidth, output power and injection current.
On the importance of galactic disks in the dynamics of spiral galaxies
Authors: DUSSERRE Tanguy 
Published: October 2022

Abstract
The author wants to estimate precisely how the gravitational field evolves in the particular shape of a spiral galaxy. This article first identifies the model used for the dynamics of spiral galaxies, which is a speed decreasing with r-1/2 outside of (and sometimes inside) the disk, then demonstrates that this model is mathematically flawed under Newton’s Law of Universal Gravitation. It also reminds the reader that Kepler Laws, which are equivalent to a r-1/2 speed decrease, can not be used if the mass distribution is not spheric. As the disk is commonly considered the most massive component of such galaxies, the article establishes the field created by it under correct hypotheses. It takes into account an axi-symmetric component and spiral arms that are studied separately, and obtains a mean flat rotation curve for every cylinder-shaped mass distribution without any hypothesis on ρ(r). A method for computing the mass of a spiral galaxy from its rotation curve is suggested and applied to the Milky Way and 12 other spiral galaxies. It is then found that their visible masses are enough to explain their rotation curve.
Impact of Deficit Irrigation on Growth and Water-use Dynamics of HLB-affected Citrus Trees
Authors: Kwakye Samuel , Kadyampakeni Davie M. 
Published: October 2022

Abstract
A greenhouse study was conducted from October 2019 to July 2021 at the Citrus Research and Education Center (CREC) in Lake Alfred, FL. The objective was to assess the impact of deficit irrigation on tree growth, soil water availability, stem water potential (SWP), sap flow and root growth of 2- to 4-year-old Huanglongbing (HLB)-affected ‘Valencia’ (Citrus sinensis) orange trees on ‘Kuharske citrange’ rootstock (Citrus sinensis x Poncirus trifoliata) using evapotranspiration (ET)-based irrigation schedule. A total of 20 trees were either HLB-positive or non-HLB affected and one-half of the trees was subjected to deficit irrigation (80% ET) and the other half to full irrigation (100% ET). For HLB-affected trees irrigated at 80% ET and 100% ET, there was no significant difference for tree height in both years. In general, there was no difference for SWP between the HLB-affected trees subjected to deficit irrigation and full irrigation. Non-HLB trees subjected to 100% ET and 80% ET had greater sap flow compared to HLB-affected trees subjected to 100% and 80% ET. Sap flow for the period of March-April and June-July 2021 was comparable between HLB-affected trees at all irrigation rates. Maximum sap flow occurred between 11 and 16 h for HLB-affected trees during for the three measurement periods. HLB-affected trees used an average of 1.6 mm day− 1 while non-HLB trees used 2.1 mm day− 1. On average, healthy trees (non-HLB) used about 20% more water than HLB-affected trees. For HLB-affected trees, irrigating at 80% ET may be appropriate for achieving water savings under controlled environments.

Abstract
background and aim of the study: Several studies have compared early and mid-term outcomes of on-pump coronary artery bypass grafting (CABG) and off-pump CABG. However, there is still an ongoing debate on this matter, especially in patients with triple-vessel coronary artery disease (3VD).
Methods: We randomly assigned 274 consecutive patients with 3VD to two equal groups to undergo on-pump CABG or off-pump CABG. The primary outcome was major adverse cardiac and cerebrovascular events (MACCE), including all-cause mortality, acute coronary syndrome, stroke or transient ischemic attack, and the need for repeat revascularization. The secondary outcomes were postoperative infection, ventilation time, duration of ICU admission, length of hospital stay, and renal failure after surgery.
Results: The mean follow-up duration was 31.1 ± 5.9 months. The mean age of patients was 61.4±9.3 years (range: 38 to 86), and 207 (78.7%) were men. There were 15 (11.2%) and 9 (7.0%) MACCE occurrence in on-pump and off-pump groups, respectively (P-value =0.23). None of the MACCE components, including CVA, non-fatal MI, and revascularization, did not significantly differ between on-pump and off-pump groups. We observed no difference in the occurrence of MACCE between off-pump and on-pump groups in multivariate regression analysis (HR=0.57; 95% CI: 0.24–1.32; P-value=0.192). There were no statistical differences in postoperative outcomes between the off-pump and on-pump CABG groups.
Conclusions: We found no significant differences between on-pump and off-pump CABG in the rate of MACCE and postoperative complications incidence when surgery is performed in the same setting by the same surgeon. (IRCT20190120042428N1)

Authors: LELLOUCHE Noura , YAHIAOUI Kenza , KELLOU Abdelhamid , ABERKANE Sabrina MESSAOUD 
Published: October 2022

Abstract
In the present work, plasma generated by fundamental radiation from a Q-switched Nd:YAG laser focused onto a zinc based alloy is studied spectroscopically. The quantification of the zinc based alloy using the calibration free- laser induced breakdown spectroscopy (CF-LIBS) is only possible under the assumption of local thermodynamic equilibrium (LTE). In this study, we investigated the spatiotemporal evolution of plasma parameters (Te, Ne) as well as the spatiotemporal evaluation of LTE in order to find regions where LTE is valid. For an accurate plasma temperature estimation, only times ranging from 0.8 µs to 6 µs and for axial distance from 0.6 to 2.6 mm were chosen. The electron temperature values were calculated using the Saha-Boltzmann method applied on neutral and singly ionized copper lines, while the electron number density was calculated using the Stark broadened profile of the Hα line using the relation of Gigosos.

Published: October 2022

Abstract
Objectives

The primary aim of this study was to compare the anesthetic efficacy of the intraseptal anesthesia (ISA) obtained with three doses of 4% articaine with 1:100,000 epinephrine (4%Ar + Ep) for scaling and root planing (SRP), using a computer-controlled local anesthetic delivery system (CCLADS). Secondary aims were to compare the clinical anesthetic parameters in relation to different jaw regions and examine the possible influence of sex and smoking habits on them.

Materials and Methods

SRP under ISA obtained with different doses (0.1 ml, 0.2 ml, and 0.3 ml) of 4%Ar + Ep was performed in 360 patients. The success rate, onset, duration of soft tissue anesthesia, the anesthetic field widths were recorded by pinprick testing.

Results

The anesthesia success was high (90–95%). The onset was immediate. The duration and anesthetic field widths showed a dose-related significance, however without a consistent sex-related or smoking-related significance. The multiple logistic regression analysis revealed a 2-fold higher chance of anesthesia success by increasing the dose, and increased bleeding on probing-related and female sex-reduced probability of anesthesia success.

Conclusions

ISA obtained with 0.3 ml of 4%Ar + Ep delivered by computer-controlled local anesthetic delivery system provided a high anesthetic success and the adequate clinical anesthetic parameters for SRP in all regions of both jaws.

Clinical Relevance

ISA obtained with 4%Ar + Ep provides an effective anesthesia for SRP. Anesthetic success rate may be reduced in the presence of gingival inflammation and in females, as well.

SiamLight: lightweight networks for object tracking via attention mechanisms and pixel-level cross-correlation
Authors: Lin Yu-e , 单 目标追踪 , Liang Xingzhu , Xia Chenxing 
Published: October 2022

Abstract
Despite Siamese-based trackers have achieved great success in recent years, researchers have focused more on the accuracy of trackers than their complexity, which leads to their inapplicability in some scenarios, and the real-time speed can be greatly limited. In this work, we propose a lightweight network method called SiamLight for object tracking. MobileNet-V3 is selected as the backbone network. The PG-corr module is added as the feature fusion module, a strategy that decomposes the template feature into spatial and channel kernels, reducing the matching regions and suppressing the effect of similar interference. In addition, we also add the CSM module, which carries out attention to the channel and spatial simultaneously. CSM module not only reduces the number of parameters but also ensures that it can be integrated into existing network architectures as a plug-and-play module. Finally, multiple separable convolution blocks are added to the classification and regression branches to meet our lightweight parameters and Flops requirements. The experiments on LaSOT, VOT2018, VOT2019, OTB100, and UAV123 benchmarks show that the method has fewer Flops and parameters than state-of-the-art trackers.

Published: October 2022

Abstract
Cry toxins produced by Bacillus thuringiensis (Bt) are toxic to Lepidoptera, Coleoptera, and Diptera, but display very low activity against aphids. Recently, Cry41-related toxin was found with moderate toxicity against Myzus persicae. This study focused on constructing Cry41-related mutants against M. persicae based on its interaction with Cathepsin B. First, eight key interacting residues in Cry41-related toxin were identified using alanine scanning and site-directed saturation mutagenesis. Subsequently, the positive mutant Cry41-7M protein (mutation of Gly48, Ile59, Lys364, Gln367, Gln377, Tyr378, and Ser400 to Tyr, Ala, Arg, Lys, Lys, Lys, and Ala in Cry41-related toxin, respectively) and the negative mutant Cry41-6A protein (mutation of Gly48, Lys364, Gln367, Gln377, Tyr378 to Ala and mutation of Pro453 to Glu in Cry41-related toxin) were constructed, expressed in vitro and purified. We then found that Cry41-7M protein performed slightly stronger than Cry41-related toxin in enhancing the enzymatic activity of Cathepsin B, whereas Cry41-6A protein did not affect Cathepsin B activity. A further bioassay showed that, in contrast to a decreased mortality caused by Cry41-6A protein, the mortality caused by Cry41-7M protein was marginally higher than that of Cry41-related toxin (1.7-fold). These results are expected to open new avenues for improving Cry aphidicidal activity.

Published: October 2022

Abstract
Context
The restoration of mangroves is an significant challenge within the protection of coastal habitats. Predicting the distribution of dominant species in mangrove communities is essential for the appropriate selection of species and spatial planning for restoration.
Objectives
We explored the spatial distribution of six mangrove species including their related environmental factors, thereby identifying potentially suitable habitats for mangrove protection and restoration.
Methods
Based on six dominant mangrove species that occur in the Beibu Gulf of Guangxi, we used linear correlation analysis to screen environmental factors. In addition, we used the maximum entropy model to analyze the spatial distribution of potentially suitable areas for mangrove afforestation. Based on spatial superposition analysis, we identified mangrove conservation and restoration hot spots.
Results
Our findings indicate that the main factors affecting the distribution of suitable mangrove habitat in the Beibu Gulf are topographic factors, followed by bioclimatic factors, land-use type, marine salinity, and substrate type. We identified 13,816 hm2 of prime mangrove habitat in the Beibu Gulf, primarily distributed in protected areas. The protection rate for existing mangroves was approximately 42.62%.
Conclusions
We identified the dominant environmental factors and their thresholds for the distribution of six mangrove species and identified the spatial distribution of individual species and location of suitable rehabilitation sites. According to the predicted spatial distribution of mangrove plants, our findings suggest that mangrove restoration should be based on suitable species and sites.
