Ambient Noise Tomography Using a Nodal Seismic Array Reveals Evidence for Igneous Intrusion Contributed to Ore Deposits in South China
Authors: Li MingRui , Fang Hongjian , Gao Rui 
Published: September 2023

Abstract
The causes of the large-scale and intense magmatism in South China and its coeval metallogenic processes in the Mesozoic have been debated, due partly to the lack of a high-resolution crustal model. In this study, we deploy ∼500 nodal seismometers around the Nanling metallogenic belt in South China, including one linear array across the metallogenic belt and one 2D array around the Fankou ore deposit: a deposit that hosts large amounts of lead and zinc in China. The derivation of the Moho and the intracrustal structures with receiver function imaging using the linear array was conducted in a separate study. Here, we focus mainly on the shallow shear wavespeed structure in the upper crust (from the surface to about 8 km depth) using ambient noise tomography with the 2D array data. We find low-shear wavespeed anomalies (VS&lt;2.8  km/s) associated with a basin down to about 3.0 km and several high-shear wavespeed anomalies (VS&gt;3.6  km/s) below 6.0 km adjacent to the Fankou ore deposit, which we interpret as the crystallized igneous intrusions in the Mesozoic. Gravity modeling shows that the high density anomaly derived using the wavespeed model is required to improve the data fitting. Considering the temperature derived from a typical geothermal gradient is insufficient for mineralization, we propose that the fluid and heat brought by the igneous intrusion might contribute to the mineral concentration of the Fankou ore deposit. This observation is consistent with geochemical and petrological evidence of diabase and quartz diorite veins in the study region. The experiment shows that ambient noise tomography using dense nodal arrays has the potential in resolving the favorable conditions for ore formation and may play a role in future ore exploration.

In breeding, biofortification is aimed at enriching the edible parts of the plant with micronutrients. Within the framework of this strategy, molecular screening of collections of various crops makes it possible to determine allelic variants of genes, new alleles, and the linkage of allelic variants with morphophysiological traits. The maize (Zea maysL.) is an important cereal and silage crop, as well as a source of the main precursor of vitamin A – β-carotene, a derivative of the β,β-branch of the carotenoid biosynthesis pathway. The parallel β,ε-branch is triggered by lycopene-ε-cyclaseLCYE, a low expression of which leads to an increase in provitamin A content and is associated with the variability of the 5’-UTR gene regulatory sequence. In this study, we screened a collection of 165 maize inbred lines of Russian selection for 5’-UTRLCYEallelic variants, as well as searched for the dependence ofLCYEexpression levels on the 5’-UTR allelic variant in the leaves of 14 collection lines. 165 lines analyzed were divided into three groups carrying alleles A2 (64 lines), A5 (31) and A6 (70), respectively. Compared to A2, allele A5 contained two deletions (at positions -267–260 and -296–290 from the ATG codon) and a G251→T substitution, while allele A6 contained one deletion (-290–296) and two SNPs (G251→T, G265→T). Analysis ofLCYEexpression in the leaf tissue of seedlings from accessions of 14 lines differing in allelic variants showed no associations of the 5’-UTRLCYEallele type with the level of gene expression. Four lines carrying alleles A2 (6178-1, 6709-2, 2289-3) and A5 (5677) had a significantly higher level ofLCYEgene expression (~0.018–0.037) than the other 10 analyzed lines (~0.0001–0.004), among which all three allelic variants were present.
Studies on Betterutilization of Jute (Corchorus olitorius) Plants Harvested for Seeds in South India-Development of a Novelmethod and Machine: Part-I
Authors: Pathan Yasin , Kumar G.B. Veeresh 
Published: September 2023

Background: No study has been conducted on how to utilize or minimize the agro-waste produced from the jute seed crop of dryland farming in the areas of Bapatla, Palnadu, and Guntur districts of Andhra Pradesh state until now. This agro-waste is essentially a wasted natural fibre resource. This fibrous plant's processing waste is huge in terms of quantity. It is a mix of broken hurd, cut pieces of fibre, and crushed seedpods of a post-vegetative jute plant. It will be a great advantage to the farmer community if fibre is managed to be separated prior to seed extraction. This is only possible if the fibre source (the main stem) and the seed source (the branches) are separated. Based on this, the current study aimed to: (i) extract and test fibre for quality; and (ii) develop a novel method and an ergonomic machine to facilitate feasible fibre extraction without damaging seedpods. Methods: In the present study, fibre has been extracted in small qualities from post-vegetative phase jute plants and tested according to Bureau of Indian standards (IS 7032 (1986) and IS 271 (2003)) to assess the fibre quality. Engineering design approach has been followed to develop the novel machine for the separation of the source of the fibre and source of seeds. Results: Results showed that usable fibres for the textile industry could be extracted from post-vegetative jute plants, and that the separation of the sources of fibre and seed could be facilitated with the use of developed machinery and methodology.

Des pouvoirs de police judiciaire donnés à des agents contractuels de droit privé de l’Office national des forêts
Authors: Cinotti Bruno 
Published: September 2023

La récente modification du code forestier, par l’ordonnance n° 2022-839 du 1er juin 2022 et son décret d’application, a pour effet principal de donner aux agents contractuels de droit privé de l’Office des prérogatives qui ne diffèrent guère de celles des gardes des bois et forêts des particuliers : pouvoir de constater par procès-verbal les infractions mais pas de les rechercher, pouvoir de relever l’identité, pas de pouvoir de porter une arme, pas de port d’un uniforme. Dans ces conditions, on peut se demander s’il n’eût pas été plus simple d’autoriser le directeur général de l’Office à commissionner ces personnels de droit privé comme gardes particuliers, comme cela avait été envisagé il y a quelques années.
Messages clés• La création de cette nouvelle catégorie d’agents de constatation vient compliquer encore plus la police des propriétés forestières.

Abstract
Studies on air quality in rural environments are fundamental to obtain first-hand data for the determination of base emissions of air pollutants, to assess the impact of rural-specific airborne pollutants, to model pollutants dispersion, and to develop proper pollution mitigation technologies. The literature lacks a systematic review based on the evaluation of the techniques and methods used for the sampling/monitoring (S/M) of atmospheric pollutants in agricultural settings, which highlights the shortcomings and the need of future studies in this field. The aim of this work is to review the study design applied for on-field monitoring campaigns of airborne pollutants in rural environments, and to discuss the possible needs and future developments in this field. Results of this literature review, based on the revision of 23 scientific papers, allowed to indicate: (i) the basic characteristics related to the study design that should always be reported; (ii) the main techniques and analyses used in exposure assessment studies conducted in this type of settings; (iii) contextual parameters and descriptors of the S/M site, that should be considered to best support the results obtained from the different studies. Future studies carried out to monitor the airborne pollution in the rural/agriculture field should consider the most important boundary information, to better characterize the S/M site. In addition, the study design could include the use of multiparametric monitors for the contextual measurement of different atmospheric pollutants (as well as meteorological parameters), because of the complex system in which these S/M are performed.
Comparative Study of PID, PD, LQR, and LQR-PD Regulators for Quadrotor Stabilization and Trajectory Tracking
Authors: Djizi Hamza , Zahzouh Zoubir 
Published: September 2023

Abstract
Quadrotors, a type of unmanned aerial vehicle, utilize four rotors for precise lift and control, making them highly versatile for a variety of tasks, such as delivery, inspection, mapping, and monitoring. The growing importance of quadcopters is due to their ability to perform a variety of tasks, such as mapping, inspection, surveillance, and delivery. However, their design and four motors make them inherently unstable and difficult to control, which can limit their potential. To improve stability, four controllers (Proportional Derivative, Proportional Integral Derivative, Linear Quadratic Regulator, and Linear Quadratic Regulator-Proportional Derivative) were tested on a quadcopter Simulink model created with MATLAB/SIMULINK. Simulation results showed that the Linear Quadratic Regulator-Proportional Derivative controller was the most effective in terms of stabilization and speed, particularly for hovering along the x and y axes. This controller was found to be reliable and efficient, providing a smooth and fast response. Tuning these controllers can optimize the quadcopter's stability, accuracy, and speed, enabling them to perform a wider range of tasks.

Abstract
Objective: Scutellaria baicalensis (SB) and polygonatum, two traditional Chinese medinces, are both known to suppress cancer. However, the mechanism and effect of combined treatment of them for lung cancer are rarely known. Investigating the combined effect of SB and polygonatum (hereafter referred to as HH) in potential mechanism of lung cancer is required.
Methods: Based on the theory of Chinese medicine and network pharmacology, In the in vivo experiment, a mouse model of carcinoma in situ was constructed and lung carcinoma in situ tissues were collected for proteomics analysis, ematoxylin-eosin staining and CK19 immunohistochemistry. In the in vitro experiment，lung cancer A549 cells at logarithmic growth stage were taken and the inhibitory effect of HH on the proliferation of A549 cells was detected by CCK8 method. The expression of PON3 was detected by quantitative polymerase chain reaction and Western Blot. In addition, the effect of HH on the induction of apoptosis in A549 cells and the changes of membrane potential and ROS content were detected by flow cytometry. The changes of PON3 content in ER is observed by laser confocal microscopy, while the effects of HH on the expression of apoptosis-related proteins and ER stress-related proteins in A549 cells were examined by Western blot.
Result: By searching the TCMSP database and symmap database, the respective target genes of the double yellow were mapped into protein network interactions (PPI), and using Venn diagrams to show 38 genes in common between the double yellow and lung cancer, thus HH was found to play a role in the treatment of lung cancer. In vivo experiments showed that in a lung carcinoma in situ model, lung tumor tissue was significantly lower in the HH group compared to the control group, and PON3 was shown to be downregulated by lung tissue proteomics analysis. The combination of HH was able to inhibit the proliferation of A549 cells in a concentration-dependent manner (P < 0.0001). The expression levels of apoptosis-related proteins and ER stress proteins were significantly increased and the expression levels of pon3 and anti-apoptosis-related proteins were decreased in A549 cells. At the same time, knockdown of PON3 could inhibit tumor cell proliferation (P < 0.0001). The combination of different concentrations of HH significantly induced apoptosis in A549 cells (P＜0.05; P＜0.0001), increased ROS content (P＜0.01), and damaged mitochondrial membrane potential of A549 cells (P＜0.05; P＜0.0001), and significantly increased the expression levels of apoptosis-related proteins and ER stress proteins in lung cancer A549 cells.
Conclusion：HH inhibits proliferation of lung cancer A549 cells by down-regulating PON3-induced apoptosis in the mitochondrial and ER pathways
Evaluating the effect of repair using direct laser metal deposition on the fracture resistance of the cracked 1.2714 tool steel component
Authors: Rezaeehajideh Mojtaba , Farahani Mohammadreza 
Published: September 2023

Abstract
Hot work steel DIN1.2714 (56NiCrMoV7) has become a widely used material in making all kinds of industrial molds such as forging, punching, and coining due to its excellent machinability, moderate corrosion resistance, and relatively low cost. The cyclic performance of these molds will lead to the formation of surface cracks on the surface of these molds over time. Repairing these cracked parts is one of the most widely used topics in the industry, and in this research, the laser cladding method was used to repair the surface of these molds. Tensile fracture testing was performed according to ASTM E1820 guidelines on single-edge cracked specimens that were repaired by the DLMD process. In this study, the effect of laser cladding process parameters (laser power and percentage of reinforcing nanoparticles) as well as the effect of crack length on the remaining strength were investigated. In the following, the experimental displacement field obtained from the analysis of digital image correlation was used to create boundary conditions for a finite element post-processing model. The finite element model was calculated using a developed code and the fields of stress and strain as well as the J- integral parameter for coated and uncoated samples. The results show that by increasing the laser power from 150 W to 450 W and by increasing the percentage of nanoparticles of Sic from 0–5%, the failure load of the samples increases by 171% and 139%, respectively, and the J-integral parameter is reduced by 32% and 41% respectively. On the other hand, it was observed that by reducing the crack length from 25 mm to 3 mm, the failure load of the samples increased by 158% and 240%, respectively, and the J-integral parameter also decreased by 55% and 40% respectively.
Stereotype Threat Effect on CPR Performance: A Randomized Controlled Mannequin Study
Authors: Tumer Murat , Korkmaz Leman , Üzümcügil Filiz , Yılbaş Aysun Ankay , Kılıçaslan Banu , Akıncı Seda Banu 
Published: September 2023

Abstract
Background:
Stereotype threat (ST) can lead to decreased performance when individuals face the possibility of confirming negative stereotypes associated with their group. During the Covid-19 pandemic, non-Intensive Care Unit physicians (non-ICUp) were assigned to work in ICUs. However, social media emphasized the inadequacy of knowledge and skills among these physicians. Given the negative judgments, the study aimed to evaluate the CPR performances of these physicians and investigate the effect of ST.
Method:
A total of 63 non-ICUp and 53 ICUp physicians working in Covid-19 ICUs were randomly assigned to control and experimental groups. In the experimental group, ST was manipulated by presenting the study's aim as measuring the difference in CPR performances between ICUp and non-ICUp physicians. The control group received no information. Participants were videotaped while performing a standard CPR scenario and evaluated by independent instructors and mannequin scores.
Results:
Overall CPR scores were higher among ICUp. Non-ICUp physicians performed better in the ST condition regarding effective chest compression (p = .02) and correct compression rates per minute (p = .02) compared to the control condition. However, ICUp had lower scores for correctly placing chest compressions in the ST condition (p = .03).
Conclusion:
The higher CPR performance among ICUp was expected. However, the hypothesis suggesting lower performance for non-ICUp under ST conditions was not supported. Inconsistent results regarding the ST effect could be influenced by moderating factors such as task difficulty, knowledge about the existing stereotype, and motivation to perform well. The interaction between the physicians' specialty and situational factors highlights the importance of creating realistic training environments that simulate high-pressure situations, ultimately contributing to the development of competent and confident healthcare professionals. Future research should further explore the impact of ST-based training on interactions and performance among different healthcare professionals.

Abstract
Ni/SBA-15 meso-structured catalysts modified with Chromium and CeO2 (Ni-Cr-CeO2/SBA-15) were utilized to produce hydrogen from glycerol steam reforming (GSR). The catalysts were synthesized by a one-pot hydrothermal process and extensively characterized by analytical techniques such as N2 adsorption-desorption (BET), H2-temperature programmed reduction (H2-TPR), powder X-ray diffraction (PXRD), Inductively coupled plasma-optical emission spectrometry (ICP-OES), and Transmission electron microscopy (TEM). Overall, the Ni-based catalysts exhibited higher glycerol conversion − 12Ni-SBA-15-99.9%, 12Ni3CeO2-SBA-15-89.4% and 8Ni4Cr3CeO2-SBA-15-99.7%. Monometallic 12Ni/SBA-15 performed exceptionally well, while 12Cr/SBA-15 performed poorly with the highest 71.48% CO selectivity. For short-term GSR reactions, CeO2 addition to 12Ni/SBA-15 did not have any effect, whereas Cr addition resulted in 32% decrease in H2 selectivity. The long-term stability studies of 12Ni-SBA-15 showed H2 selectivity of ~ 64% and ~ 98% glycerol conversion. However, its activity was short-lived. After 20-30hrs, the H2 selectivity and conversion dropped precipitously to 40%. The doping of mesoporous Ni/SBA-15 with Cr and CeO2 remarkably enhanced the long-term stability of the catalyst for 12Ni3CeO2-SBA-15, and 8Ni4Cr3CeO2-SBA-15 catalyst with ~ 58% H2 selectivity and ~ 100% conversion for the entire 60hrs. Nonetheless, Cr and CeO2 seem to improve the shelf-life of Ni-SBA-15 via different mechanistic pathways. CeO2 mitigated Ni poisoning through coke oxidation whereas Cr bolstered the catalyst stability via maintaining a well-defined pore size and structural integrity of the heterogeneous framework, thereby restricting structural collapse, and hence reducing sintering of the Ni active sites during the long-term 60hrs continuous reaction.

Abstract
Proinflammatory cytokine interleukin (IL)-6 was associated with disease severity in patients with COVID-19. The mechanism underlying the excessive production of IL-6 by SARS-Cov-2 infection remains unclear. Respiratory viruses initially infect alveolar epithelial cells that produce various immunomodulatory inflammatory mediators. Here, we show that pretreatment of human bronchial epithelial cells (NCl-H292) with interferon (IFN)-γ markedly increased IL-6 production induced by the toll-like receptor (TLR) 3 agonist poly(I:C). A similar priming effect of IFN-γ on poly(I:C)-induced IL-6 production was observed in human primary bronchial and A549 epithelial cells. TLR3 knockdown using siRNA in NCl-H292 cells diminished the priming effects of IFN-γ on poly(I:C)-induced IL-6 production. Furthermore, the Janus kinase (JAK) inhibitor tofacitinib inhibited IFN-γ priming-induced upregulation of TLR3 and suppressed poly(I:C)-induced IL-6 production. Quantitative chromatin immunoprecipitation revealed that IFN-γ stimulated histone modifications associated with the IL-6 gene locus. Finally, IFN-γ priming significantly increased lung IL-6 mRNA and protein levels in the alveolar lavage fluid of mice with poly(I:C)-induced bronchial inflammation. Thus, priming bronchial epithelial cells with IFN-γ markedly increases poly(I:C)-induced IL-6 production via JAK-dependent upregulation of TLR3 and IL-6 gene locus chromatin remodeling. These mechanisms may be involved in severe respiratory inflammation with excess production of IL-6 following infection with RNA viruses.
