Published: August 2022

Introduction: According to the Indonesian Demographic and Health Survey (IDHS) in 2017, young women (63.9%) in maintaining cleanliness during menstruation are still lacking due to low knowledge and information about personal hygiene during menstruation. SMP Negeri 1 Sampit is located in Central Kalimantan where most of the students do not have knowledge about menstrual hygiene management.
Methods: The activities used in this community service program were in the form of health education to 120 students of 7th and 8th grades. The community service events carried out through this webinar include opening, pretest, giving material, and closing with a post test. The pretest was carried out before giving the material to determine the participant's initial understanding of menstrual hygine management.
Results: Knowledge related to adolescent growth and development scored well as many as 19 people (15.83%) then during the good posttest it became 63 people (52.50%). Knowledge related to menstrual hygiene management during the pretest who got a good score was only 20 people (16.67%) and 72 people (60%) good in posttest. While the knowledge related to mood disorders in adolescents who got a good score at the pretest was 21 (17.5%) and 70 people (58.3%) had a good score in posttest.
Conclusion: Community service activities conducted in the form of online webinars to provide health education and modules to teachers can improve knowledge and practice of menstrual hygiene management as an early effort in maintaining and caring for the health of the female reproductive organs.
Identification of Novel Multi-Omics Expression Landscapes and Meta-Analysis of Landscape-Based Competitive Endogenous RNA Networks in ALDH+ Lung Adenocarcinoma Stem Cells
Authors: Yang Wei , Liang Yong , Zheng Yuan Yuan , Luo Hai Tao , Yang Xiao Fei , Li Fu Rong
Published: August 2022

ALDH+ H1975 lung adenocarcinoma stem cells (LSCs) are a rare cell population identified in lung adenocarcinoma (LUAD). LSCs can self-renew, drive tumor initiation, growth, metastasis, and recurrence, and are also the predominant cause of poor prognosis due to their intrinsic resistance to drugs and chemotherapy. Consequently, LSCs are a promising target for LUAD therapy. Noncoding RNAs (ncRNAs), including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), exert many significant regulatory functions in the pathogenesis of human cancers, showing the necessity for a comprehensive understanding of the mechanisms that underlie lung carcinogenesis. Nonetheless, research on many known transcripts and messenger RNAs (mRNAs) has already generated new information. Unknown biomarkers in ncRNAs and systematic and comprehensive interrelation with unknown ncRNAs and mRNAs may provide further insights into the biology of LUAD. Herein, a set of novel ncRNAs that include miRNAs, lncRNAs, circRNAs, were identified and differentially expressed patterns of ncRNAs and mRNAs in LSCs and ALDH- H1975 LUAD tumor cells (LTCs) were obtained using stringent bioinformatics pipelines. Through a meta-analysis of the identified landscapes, novel competitive endogenous RNA (ceRNA) networks were constructed to reveal the potential molecular mechanisms that regulate the hallmarks of LSCs and LTCs. This study presents a summary of novel ncRNAs and the fundamental roles of differentially expressed ncRNAs implicated in the activity of LSCs and LTCs. In addition, the study also provides a comprehensive resource for the future identification of diagnostic, therapeutic, and prognostic biomarkers in LUAD.
Effects of Data Augmentations on Speech Emotion Recognition
Authors: Atmaja Bagus Tris , Sasou Akira
Published: August 2022

Data augmentation techniques recently gained more adoption in speech processing, including speech emotion recognition. Although more data tends to be more effective, there may be a trade-off in which more data will not provide a better model. This paper reports experiments on investigating the effects of data augmentation in speech emotion recognition. The investigation aims at finding the most useful type of data augmentation and the number of data augmentations for speech emotion recognition. The experiments are conducted on the Japanese Twitter-based emotional speech corpus. The results show that for speaker-independent data, two data augmentations with glottal source extraction and silence removal exhibited the best performance among others, even with more data augmentation techniques. For the text-independent data (including speaker and text-independent), more data augmentations tend to improve speech emotion recognition performances. The results highlight the trade-off between the number of data augmentation and the performance of speech emotion recognition showing the necessity to choose a proper data augmentation technique for a specific application.

Published: August 2022

Callinectes danae and C. ornatus are economically important species in several countries, including Brazil. Therefore, this study aimed to estimate the L50 of these species using morphological, morphometric, and physiological data. The estimated values were statically compared and results from previous studies were analyzed to verify latitudinal variations among the sizes of sexual maturity at different latitudes of the Brazilian coast. Individuals were monthly collected in the Paraguaçu River estuary from August 2013 to July 2014, using cage traps. L50 estimates for C. danae were morphological=55.80 mm, morphometric=59.04, mm, and physiological=60.41 mm for males and morphological=54.63 mm, morphometric=55.33 mm, and physiological=57.29 mm for females. Considering C. ornatus, estimates were morphological=42.63 mm, morphometric=50.81 mm, and physiological=43.95 mm for males and morphological=42.33 mm, morphometric=42.75 mm, and physiological=40.43 mm for females. Our results indicated that the minimum catch sizes should be equal to 61.00 mm for C. danae and 51.00 for C. ornatus and that the mesh of traps used by fishermen must be adjusted to prevent the capture of immature animals.

Published: August 2022

The presence or absence of a fish species may be associated with the physical and chemical characteristics of the water, in addition to the state of preservation of the riparian zone. This study examined whether the taxonomic fish composition in an urban river varies along three riparian zone preservation conditions: preserved, intermediate preservation and degraded. Six urban stretches of the Sorocaba/São Paulo River were selected for this study, with monthly sampling being carried out from June 2019 to February 2020. The samplings were carried out with the aid of a sieve, dip net, and trawl. Regarding the types of margins and environmental variables, the Principal Component Analysis explained 97.49% of the data variation, axis 1, which explained 91.85% of the total variation, was formed by the variables conductivity and total dissolved solids. Axis 2, which explained 5.64% of the variation, was formed by Sun Rays% and Siltation%, being inversely proportional to Riparian Forest%. For the ichthyofauna, the samples consisted in 50,983 fish distributed in 5 orders, 8 families, and 12 species. Cyprinodontiformes had the highest abundance, with 96.96% of the total number of individuals, followed by Siluriformes (2.39%), and the sum of the other orders did not reach 1% of the total collected. According to each type of margin, it was possible to register 11,592 individuals for the Margin A – preserved, with S=8 species, being 2 exclusive (Corydoras flaveolus and Hoplosternum littorale) and 3 exotic (Coptodon rendalli, Pterygoplichthys ambrosettii, and Poecilia reticulata), the latter was dominant in all types of margins. For Margin B – intermediate preservation, 19,645 individuals were sampled, with S=5 species, no exclusive species, only exotic and more tolerant native species such as Hoplias malabaricus and Hypostomus ancistroides. For Margin C – degraded, 19,746 individuals were recorded, the largest number of species (S=10), 3 were exclusive to this type of margin (Psalidodon fasciatus, Rhamdia Quelen, and Geophagus brasiliensis). The pairwise comparison (similarity percentage) showed that the assemblage structure was different for the types of margins. The Canonical Correspondence Analysis explained 92.46% of the total data variation, showing the relationship of species to environmental data. It is evident the importance of preservation of micro-habitats still present in the locals sampled, since different anthropic pressures cause great loss of diversity, especially for native and more sensitive species.

Periprosthetic Osteolysis as a Risk Factor for Revision After Total Ankle Arthroplasty
Authors: Lee Gun-Woo , Lee Keun-Bae
Published: August 2022

Background:

Periprosthetic osteolysis after total ankle arthroplasty (TAA) is a challenging problem. This study aimed to evaluate the prevalence of and predisposing factors for osteolysis and its effects on clinical outcomes.

Methods:

We enrolled 236 patients (250 ankles) who underwent primary TAA using a mobile-bearing HINTEGRA prosthesis, with a mean follow-up of 83.5 months (range, 36 to 182 months), and subsequently divided them into 2 groups: the osteolysis group (79 ankles) and non-osteolysis group (171 ankles). Clinical and radiographic outcomes were compared between the 2 groups, and a bivariable logistic regression analysis was performed to identify predisposing factors for the development of osteolysis.

Results:

In the osteolysis group (31.6% of the 250 ankles), the mean time of detection was 28.8 months postoperatively. Forty of these ankles were closely monitored without surgical treatment. Another 29 ankles underwent bone grafting and exchange of the polyethylene inlay, and the remaining 10 ankles underwent revision TAA or arthrodesis. All clinical outcome variables were significantly lower in patients with osteolysis, compared with those without osteolysis, at the final follow-up (p < 0.05). In the investigation of predisposing factors, only rheumatoid arthritis was identified as having a significant association with an increased prevalence of osteolysis (p = 0.030).

Conclusions:

This study demonstrated that the prevalence of periprosthetic osteolysis after TAA was considerable and that the development of osteolysis negatively affected the clinical outcome. Therefore, the prevention and appropriate treatment of osteolysis are crucial for the satisfactory long-term survival of TAA.

Simulating environmental conditions for Southwest United States convective dust storms using the Weather Research and Forecasting Model v4.1
Authors: Gallagher Alex , LeGrand Sandra , Hodgdon Taylor , Letcher Theodore
Published: August 2022

Dust aerosols can pose a significant detriment to public health, transportation, and tactical operations through reductions in air quality and visibility. Thus, accurate model forecasts of dust emission and transport are essential to decision makers. While a large number of studies have advanced the understanding and predictability of dust storms, the majority of existing literature considers dust production and forcing conditions of the underlying meteorology independently of each other. Our study works to-wards filling this research gap by inventorying dust-event case studies forced by convective activity in the Desert Southwest United States, simulating select representative case studies using several configurations of the Weather Research and Forecasting (WRF) model, testing the sensitivity of forecasts to essential model parameters, and assessing overall forecast skill using variables essential to dust production and transport. We found our control configuration captured the initiation, evolution, and storm structure of a variety of convective features admirably well. Peak wind speeds were well represented, but we found that simulated events arrived up to 2 hours earlier or later than observed. Our results show that convective storms are highly sensitive to initialization time and initial conditions that can preemptively dry the atmosphere and suppress the growth of convective storms.
From Copyright Cartels to Commons and Care: A Public Infrastructure Model for Canadian Music Communities
Authors: Selman Brianne , Fauteux Brian , DeWaard Andrew
Published: August 2022

Using research on the political economy of the music industries, interviews with independent musicians about their lived experiences, and the authors' experience participating in government copyright consultations in Canada, this article discusses how the market power of major music companies, and their capture of the policy-making process through lobbying, has made copyright reform an extremely limited avenue for remedying the variety of hardships facing musicians in the streaming media era. Against the continued consolidation and concentration of power within the music industries, we explore a case study of Edmonton Public Library’s Capital City Records as an alternative model that may inspire further initiatives that advocate for artists and users. We conclude by discussing a commons-based, public infrastructure and governance model that could serve as a tool to circumvent uneven power dynamics in the music industries, facilitate stronger music communities, and provide sustainable livelihoods for working musicians in Canada.

Published: August 2022

Although pegmatites are volumetrically minor in the upper continental crust, these rocks host abundant rare metal deposits (e.g., Li, Be, Rb, Ta, and Nb). Pegmatites can be formed either by extensive fractional crystallization of granitic magmas or by low-degree partial melting of metasedimentary rocks. The Mao’ershan–Yuechengling composite batholith in the Nanling Range in the South China Block (SCB) is of early Paleozoic–Triassic age (440–381 and 236–204 Ma, respectively). Recently, hundreds of pegmatites associated with Nb, Ta, Be, Rb, and Li mineralization have been identified in this batholith. These pegmatites are hosted by granitic wall rocks. However, the relationships between the pegmatites and granitic wall rocks are not well constrained. To address this, we investigated the Mao’antang (MAT) and Tongzuo (TZ) pegmatites and their biotite granite wall rocks in the middle part of the Yuechengling pluton. Laser ablation inductively coupled plasma mass spectrometry zircon U–Pb ages revealed that the MAT pegmatites formed during the Permian (269 Ma) and Triassic (231 Ma) and that the MAT biotite granite wall rock records two stages of magmatic activity (271 and 231 Ma) that are coeval with the pegmatites. The TZ pegmatites probably formed during the Triassic (235 Ma), and the TZ biotite granite wall rock formed during the Silurian (435 Ma). The MAT biotite granite and pegmatites (εNdt=−12.0 to −10.6; εHft=−8.0 to −1.0), TZ pegmatites (εNdt=−10.4 to −6.1), and TZ biotite granites (εNdt=−9.1 to −8.7; εHft=−7.7 to −4.1) have enriched whole-rock Nd and zircon Hf isotopic compositions that are similar to those of early Paleozoic and Triassic S-type granites in the SCB. In addition, the whole-rock Pb isotopic compositions of the MAT and TZ pegmatites and granites are distributed along the upper crust evolution line. We suggest that the MAT and TZ biotite granites were mainly derived from Paleoproterozoic metasedimentary rocks in the middle crust. The MAT pegmatites are fractional crystallization products of the MAT biotite granites, whereas the TZ pegmatites were formed by fractional crystallization of hidden parental S-type granites. We propose that the MAT and TZ pegmatites have potential for rare metal (Nb, Ta, Be, and Li) mineralization, as they record high degrees of fractional crystallization. The MAT and TZ areas in the middle of the Yuechengling pluton are promising targets for rare metal exploration.
A Machine Learning Approach to Real-Time Uncertainty Assessment of SAGD Forecasts
Authors: Hunyinbo Seyide , Azom Prince , Ben-Zvi Amos , Y. Leung Juliana
Published: August 2022

Field development planning and economic analysis require reliable forecasting of bitumen production. Forecasting at the field level may be done using reservoir simulations, type curve analysis, and other (semi-)analytical techniques. Performing reservoir simulation is usually computationally expensive, and the nonuniqueness of a history-matched solution leads to uncertainty in the model predictions and production forecasts. Analytical proxies, such as Butler’s model and its various improvements, allow for sensitivity studies on input parameters and forecasting under multiple operational scenarios and geostatistical realizations to be conducted rather quickly, despite being less accurate than reservoir simulation. Similar to their reservoir simulation counterparts, proxy models can also be tuned or updated as more data are obtained. Type curves also facilitate efficient reservoir performance prediction; however, in practice, the performance of many steam-assisted gravity drainage (SAGD) well pairs tends to deviate from a set of predefined type curves.

Historical well data is a digital asset that can be utilized to develop machine learning (ML) or data-driven models for production forecasting. These models involve lower computational effort than numerical simulators and can offer better accuracy compared to proxy models based on Butler’s equation. Furthermore, these data-driven models can be used for automated optimization, quantification of geological uncertainties, and “What If” scenario analysis due to their lower computational cost.

This paper presents a novel ML workflow that includes a predictive model development using the random forest algorithm, clustering (to group well pairs by geological properties), Bayesian updating, and Monte Carlo sampling (for uncertainty quatification) for the forecasting of real-world SAGD injection and production data. The training data set consists of field data from 152 well pairs, including approximately 3 years of operational data. Each well pair’s data set involves data that are typically available for an SAGD well pair (e.g., operational data, geological, and well design parameters). This ML workflow can update predictions in real time and be applied for quantifying the uncertainties associated with the forecasts, making it an important step for development planning. To the best of the author’s knowledge, this is the first time ML algorithms have been applied to an SAGD field data set of this size.

Published: August 2022

In 2019, the operator embarked on a very ambitious data acquisition project in the Bakken, with the goal of mapping far-field drainage and characterizing completion performance. The project consisted of a six-well pad (10,000 ft laterals) with a dedicated observation lateral located in the Three Forks (TF) formation instrumented with cemented pressure gauges and fiber optics along the 10,000 ft lateral. The observation lateral was offset by Middle Bakken (MB) wells ~450 ft on either side (~900 ft MB-MB well spacing). One of the MB wells was instrumented with fiber optics for cluster-level completion measurements and “frac hit” detection, while the other offset MB well was used to deploy geophones for microseismic mapping. Three different fracture treatment designs were evaluated, with the goal of understanding how fluid volume and rheology, proppant volume and size, and proppant/fluid ratio affect fracture geometry and drainage. Quantitative application of oil and water tracers was used to evaluate the productivity of each treatment design.

During the completions of the first three wells, microseismic data provided important measurements to characterize fracture geometry and “offset well” fiber provided strain data to evaluate fracture morphology (i.e., far-field fracture behavior). Stress shadowing was evaluated by combining the microseismic and strain data. These measurements were used to calibrate a hydraulic fracture model to enable more reliable predictions of fracture geometry and morphology. Cluster-level measurements of fluid distribution provided data to support increasing clusters per stage and decreasing stage count. Production has been monitored continuously for more than 12 months, including interference testing to evaluate connectivity. The pressure gauges placed along the observation lateral provided one of the first-ever measurements of far-field drainage as a function of fracture treatment design (450 ft in between two producing wells with 900 ft well spacing).

The results show that MB wells can drain the TF at distances of 450 ft, and fracture treatment design can significantly impact drainage and productivity. Although the evaluation, modeling, and trials are ongoing, these results may add significant value by enabling Bakken development with fewer, more productive wells in some portions of the basin.
Coastal hypoxia drives microbial diversity: Elucidation through 16S rRNA amplicon sequencing

Published: August 2022

The formation of oxygen-depleted zones in the bottom waters is one of the most widespread phenomena in coastal areas. Upwelling episodes occurring along the west coast of India due to the southwest monsoon leads to an increase in biological productivity which further lowers the dissolved oxygen in the upwelled waters, which intensifies annually between June and October. Here, we have determined the changes in the microbial community in response to the varying oxygen levels and other physicochemical parameters at the Candolim Time Series Station using high-throughput sequencing. Amplicon Sequence Variants across all the samples collected in different seasons were mostly affiliated to the phyla Proteobacteria, Actinobacteria, Bacteroidetes, Verrucomicrobia, Chloroflexi, Firmicutes and Planctomycetes, with the most dominant being Proteobacteria (21–41%). Statistical analysis revealed that microbial diversity differed significantly with changing DO, ammonia, nitrate and nitrite concentrations during different seasons. The microbial community shift due to seasonal hypoxia results in the differential biogeochemical cycling of essential nutrients with certain years seeing redox conditions up to sulphate reduction, while certain years seeing only nitrogen loss. Future scenario of global warming will serve as a big challenge for understanding the role of microbial diversity and its implications in the cycling of natural elements.

Published: August 2022

Capacitive deionization (CDI) is a relatively new technique that uses electric double layers (EDLs) effects, high affinity chemical groups, redox-active materials, and membranes capacitive electrosorption principle for the desalination. In this paper, hydrothermal synthesis of CFO metal oxide NPs coupled with the vacuum filtration method, or the freeze-drying method is used to fabricate high-performance nanocomposite: CFO-Graphene, CFO-CNTs, and CFO-3DrGO. Two times of hydrothermal reaction methods were conducted to fabricate the CFO-3DrGO Nanoengineered as a pseudocapacitive/EDL electrode. The results have demonstrated that the SAC of CFO–3DrGO/CFO (64.5 mg g− 1) is greater than that of the CFO–graphene/CFO (55.16 mg g− 1) and CFO–CNTs/CFO (21.5 mg g− 1) due to the better surface area of the CFO–3DrGO nanocomposite (330 m2 g− 1). The higher surface area of the CFO–3DrGO is due to the porous and interconnected 3D structure of the 3DrGO, and it provides a larger surface area to form EDL capacitance. In addition, the added porous 3DrGO entangled with the spinel crystals (CoFe2O4) in the composite allowed for a quick ion diffusion across the interconnected open macroporous structures.

Published: August 2022

Ferroptosis is a special form of regulated cell death, which is reported to play an important role in a variety of traumatic diseases by promoting lipid peroxidation and devastating cell membrane structure. PFD is a kind of disease affecting the quality and health of many women’s lives, which is closely related to the injury of the pelvic floor muscles. It has been clinically discovered that there is anomalous oxidative damage in the pelvic floor muscles of female patients with PFD, but the specific mechanism is still unclear. In this study, we explored the relationship between ferroptosis and mechanical stretch-induced pelvic floor muscle injury, whether obesity would make the muscles more susceptible to ferroptosis. Our results, in vitro, showed that mechanical stretch could induce oxidative damage to myoblasts and trigger ferroptosis. In addition, GPX4 and 15LOX-1 showed significant changes coinciding with ferroptosis, which was much more obvious in PA-treated myoblasts. Furthermore, ferroptosis induced by mechanical stretch could be rescued by ferroptosis inhibitor (ferrostatin-1). More importantly, in vivo, we found that the mitochondria of pelvic floor muscle shrank, which were consistent with the mitochondrial morphology of ferroptosis, and GPX4 and 15LOX-1 showed the same change observed in cells. In conclusion, our data indicate the intimate relationship between ferroptosis and mechanical injury of pelvic floor muscle, and provide a novel insight for PFD therapy.

Published: August 2022

Background
Medicinal plants have been used time immemorial to treat various ailments and diseases caused by pathogenic microorganisms attributed bioactive compounds they contain. Such compounds may have developed in plants as self-defense mechanism against pests and pathogens purposely to survive and perpetuate themselves in their ecosystem. A few studies have been conducted on L. cornuta. The study sought to determine the effect of L. cornuta leaf, stem bark and root extracts against selected bacteria.
Methods
Methanol, Dichloromethane and Aqueous extracts of L. cornuta were tested for bacteriostatic and bactericidal effects against Escherichia coli ATCC 27853, Shigella dysenteriaea ATCC 13313 and Pseudomonas aeruginosa, Staphylococcus aureus ATCC 25923. Phytochemical screening of the extracts was performed using thin layer chromatography (TLC) with Ethyl acetate: petroleum spirit at the ratio of (3:7) as the solvent system for dichloromethane extracts while dichloromethane: methanol ratio (9.5: 0.5) solvent system was utilized for methanol extracts. Cytotoxicity of the active extracts was determined using Vero E6 cell lines. The cell cytotoxicity levels were read using an ELISA scanning Multiwell spectrophotometer (Multiskan Ex Labssytems, Thermo Fisher Scientific, USA) at 562 nm and 620 nm as reference. The cytotoxic concentration responsible for lysis and death of 50% of the cells was determined using Microsoft Office Excel 2007 software by linear regression analysis.
Results
Stem, leave and root extracts showed weaker / little or no activity with zone diameter inhibition < 10mm against the selected bacteria. No activity was observed with S. aureus. Minimum inhibitory concentration (MIC) value of extracts ranged between 500mg/ml to 60 mg/ml. DCM stem bark extracts had MIC value of 62.5 mg/ml against S. dysenteriaea and 500mg/ml against S. aureus.

Aberrant expression of long non-coding RNAs (lncRNAs) is closely related to the progression of sepsis. According to research, the lncRNA MALAT1 plays an important role in the multiple organ damage caused by sepsis. However, the mechanism associated with MALAT1 in septic testicular injury is not clear. We established an animal model of LPS-induced septic testicular injury and a cellular model of LPS-induced GC-1 cell injury in mice. H&E staining was performed to detect testicular injury after LPS treatment. MALAT1, inflammatory factors and related proteins expression levels in testicular tissues were determined using qRT-PCR, western blotting and immunohistochemistry. The ROS levels in tissue were detected by MDA and SOD. MALAT1, miR-103-3p and inflammatory factors expression levels in GC-1 were detected by qRT- PCR and ELISA assay. cell viability was determined by CCK-8. Western blot, immunofluorescence assay detected proteins expression. Correlation of MALAT1, miR-103-3p and TRPV4 was verified through dual luciferase reporter and Ago2-RIP. Within the present study, our findings suggest that MALAT1 expression is elevated in both cellular and animal models. Furthermore, we discovered that MALAT1 inhibits miR-103-3p expression at the post-transcriptional level while promoting TRPV4 expression, which promotes cellular inflammation and pyroptosis. As a result, we investigated the relationship between MALAT1, miR-103-3p, and TRPV4 and discovered that MALAT1 targets miR-103-3p, whereas miR-103-3p targets TRPV4. Our study showed that MALAT1 promotes testicular inflammation and pyroptosis through modulating miR-103-3p and TRPV4 in a septic testicular injury model, suggesting that MALAT1 may be a potential therapeutic target for septic testicular injury.

The industrial wastes comprise toxic heavy metals in huge amount which is adequate to cause noxiousness to crop plants. The zinc (Zn) and nickel (Ni) are nutrients that are crucial for plant life especially for plants growth but these elements are poisonous to plants when they are present in high concentrations. The present study was conducted to isolate endophytic bacteria from Vibernum grandiflorum and to assess the endophytic bacterial strain Bacillus mycoid (Acc MW979613) and Rock phosphate potential to overcome the stress of zinc (Zn) and nickel (Ni) toxicity on wheat plant. The concentration of nickel (Ni) (100mg/kg) and zinc (Zn) (100mg/kg) was used and eight different treatments applications were made by using Bacillus mycoid (Acc MW979613) and rock phosphate. Rock phosphate (0.2g/kg) was added in soil and experiment was conducted using complete randomized design (CRD) with three replicates. The results showed that Bacillus mycoid and application of rock phosphate (RP) significantly affected the plant growth and defense system. The treatment T12 was most prominent in which the shoot length was 57%, leaf width was 13%, protein content was 20% and sugar content was 34% higher than control respectively. In (T3) Cu content was 128%, Ca content was 219% and K content was 85% and in (T4) Mn content was 326%,Na content was 449% and K content was 84% respectively. It is concluded that Zn and Ni adversely affected the growth of wheat (Triticum aestivum) plant; however combine application of Bacillus mycoid and Rock phosphate (RP) suppressed the toxicity of zinc (Zn) and nickel (Ni) and increased plant growth, enzymes activity and nutrients uptake in wheat plants. The novel endophytic bacteria (Bacillus mycoid) and rock phosphate can be useful in combination to overcome metal stress which can improve plants growth and yield.
Increasing Marginal Tendency to Tax Avoidance, Inequality and Economic Growth

According to increasing marginal tendency to tax avoidance, we establish a dynamic theoretical model and derive an optimal path of economic growth only using dimensionless parameters, which illustrates an inverted U-curve relationship between economic growth and income inequality in the long run. This finding stands in sharp contrast to the Kuznets curve—whereby inequality first increases and then decreases during economic process. Instead, the growth shows a trend of moving upward and then downward as the Gini coefficient increases. We present empirical evidence consistent with our model by controlling for endogeneity.JEL Classification: O41 , O11 , E13

Published: August 2022

The temperature-independent paramagnetic peaks are observed in the non-topological WSe2 single crystal. This is contrary to previous observation that the temperature-independent paramagnetic peaks in topological materials originate from the spin texture of the topological surface state.Weak ferromagnetic characteristic was observed from the susceptibility measurement from 300 to 5 K. The high resolution transmission electron microscope supports that the ferromagnetism originates from lattice dislocation at different layer plane and axis. The temperature-independent paramagnetism susceptibility peak might originate from the ferromagnetism induced by the lattice dislocation.PACS numbers: 73.20.At, 73.25.+i, 71.18.+y
A nondestructive compaction quality evaluation of runway construction with GPR data
Authors: Cheng lili , Lu Ji , Zhou Cheng
Published: August 2022

Compaction quality evaluation of rockfill materials is an essential link in the construction process of runway. However, the traditional on-site limited sampling detection is not only time-consuming and labor-intensive, but also destructive. To address this challenge, the application of non-destructive ground penetrating radar (GPR) in runway compaction quality detection under different compaction conditions is discussed in this paper, combining laboratory test and field investigation. It is found that the crest factor (CF) index based on Hilbert -Huang transform (HHT) analysis of GPR signal can better detect the compaction quality. Based on an runway case, through the HHT analysis of GPR signals collected in the field, it is verified that the CF index can be used to predict the relative compaction of rockfill material, and the average error rate is 4.03%. At the same time, the kriging interpolation method is used to estimate the compaction quality of any point, and the corresponding evaluation heat map of compaction quality is generated. This method can greatly shorten the detection time in the construction process and provide a certain reference for the determination of the insufficient compaction area in the construction process.
Autumn Vertical distribution of zooplankton in the Oxygen Minimum Zone of the Eastern Tropical North Pacific.
Authors: Lorda Jaime Färber , Data Bertrand Färber
Published: August 2022

A general pattern of vertical zooplankton distribution is described, including 22 MOCNESS tows with a 48-h cycle of stratified zooplankton sampling; it showed no day-night differences in the vertical distribution of zooplankton, except for euphausiids. Most zooplankton groups sampled between 500 m and 0 m migrate only across the upper 100 m. Zooplankton carbon was three times higher in the upper 100 m than in the 100–500 m layer of the water column sampled. A difference of 1/24 between the shallower layer (0–50 m) and the 150–200 m layer was found. Euphausiids migrated into the Oxygen Minimum Zone (OMZ) during the day. Zooplankton migration was restrained to the upper 100-m layer by the shallow OMZ. Twenty-four zooplankton groups were studied, showing a ~ 50% reduction in the number and abundance of these groups inside the OMZ. These findings support the Habitat Compression Hypothesis (HCH). A Principal Component Analysis showed that vertical zooplankton distribution is limited by oxygen, concentrated mostly within the upper 100 m. The two most abundant euphausiid species were the vertical migrator Euphausia lamelligera (49.3%) and the non-migrator Stylocheiron affine (39.8%). Most zooplankton assemblages do not migrate across the oxycline.
A Study of Jamming Resource Allocation Based on a Hyperheuristic Framework
Authors: Hao Zelong , Wang Xing , Wang Jundi
Published: August 2022

There are massive data and rapidly changing battlefield situations in modern electronic warfare, which is a challenge to jamming resource allocation. It is difficult for the existing optimization algorithms to balance optimization capability and calculation speed at the same time. To solve this problem, this study proposes an improved genetic selection electronic warfare operator hyperheuristic (GAEWHH) algorithm. As an emergent optimization algorithm, the hyperheuristic (HH) framework has not previously been applied to the problem of jamming resource allocation. This is a two-level algorithm framework that can isolate problem domains. The high level uses an improved genetic algorithm to search the heuristic space, and four electronic warfare operators (EWOs) based on the problem domain are designed for the low level to search the solution space. Combining different EWOs can change the population diversity, evolution direction and algorithm complexity of the GAEWHH algorithm, which improves the algorithm performance to meet battlefield situation requirements. The experiment shows that for large-scale problems, the GAEWHH algorithm is better than the mainstream evolutionary algorithm in terms of optimization capability and better than Google OR-Tools in terms of calculation speed. In this way, the GAEWHH algorithm achieves a balance between optimization capability and calculation speed.
