The Biology and Immature Stages of the Moss-Eating Flea Beetle Cangshanaltica fuanensis sp. nov. (Coleoptera, Chrysomelidae, Galerucinae, Alticini), with Description of a Fan-Driven High-Power Berlese Funnel

Simple Summary The immature stages and the biology of the moss inhabiting flea beetles are poorly understood. In this study, a new species of moss-eating flea beetles—Cangshanaltica fuanensis sp. nov. is described; the morphology of the adult and immature stages is described and illustrated. The life history and remarkable biological features of this species are revealed. Females deposit one large egg at a time; egg length equals 0.4–0.5 times the female body length. Females lay and hide each egg under a spoon-shaped moss leaf. There are only two ovarioles on each side of the ovary in the female reproductive system, which has not been reported before in Chrysomelidae. Besides, a modified fan-driven Berlese funnel is designed for faster extraction of moss inhabiting flea beetles. We suggest this improved device could also be useful for collecting other ground-dwelling arthropods. Abstract The biology of the moss and leaf litter inhabiting flea beetles is poorly understood. In this study, a new species of moss-eating flea beetles Cangshanaltica fuanensis sp. nov. is described; the morphology of adult and immature stages is examined and illustrated. Its life history and biology are studied. The remarkable and unique biological features are revealed: (1) females deposit one large egg at a time, egg length equals 0.4–0.5 times the female body length, these are unusual in Chrysomelidae; (2) females have only two ovarioles on each side of the ovary, which has not been reported in other Chrysomelidae species; (3) females lay and hide each egg under a spoon-shaped moss leaf; (4) cannibalism of a second instar larva on an egg was observed. Both adults and larvae feed on moss and are polyphagous; their feces mainly consist of un-digested moss fragments; high humidity is essential for the survival of eggs and larvae and expedites the hatching. In addition, a modified fan-driven Berlese funnel is designed for faster extraction of moss inhabiting flea beetles. This device could also be used for collecting other ground-dwelling arthropods. Its working diagram is illustrated and described.
Wnt5a and Wnt11 as acute respiratory distress syndrome biomarkers for severe acute respiratory syndrome coronavirus 2 patients

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has spread globally, resulting in declaration of pandemic emergency [1]. COVID-19 patients suffer from various symptoms of infection, including pneumonia, acute respiratory distress syndrome (ARDS) and sepsis. Some known antiviral drugs, including remdesivir, have been proposed as effective agents for the treatment of SARS-CoV-2 infection [2, 3]. Along with the development of potential therapeutics, there is urgency to mitigate the transmission and economic crisis of SARS-CoV-2 via identification of biomarkers that can rapidly indicate the severity of the disease in infected patients. Wnt ligands are secreted glycoproteins and their downstream signalling plays a pivotal role in embryonic development and tissue homeostasis. Wnt5a/Wnt11 can be used as potential ARDS biomarkers for SARS-CoV-2 patients https://bit.ly/3lxEGRA
IL-33–Stimulated Murine Mast Cells Polarize Alternatively Activated Macrophages, Which Suppress T Cells That Mediate Experimental Autoimmune Encephalomyelitis

Key Points IL-33–stimulated mast cells polarize alternatively activated macrophages. Mast cell–derived IL-6 and IL-13 polarize alternatively activated macrophages. Alternatively activated macrophages suppress T cells that mediate CNS autoimmunity. IL-33 is known to promote type 2 immune responses through ST2, a component of the IL-33R complex, expressed primarily on mast cells, Th2 cells, group 2 innate lymphoid cells and regulatory T cells, and to a lesser extent, on NK cells and Th1 cells. Consistent with previous studies, we found that IL-33 polarized alternatively activated macrophages (AAMΦ) in vivo. However, in vitro stimulation of murine bone marrow–derived or peritoneal macrophages with IL-33 failed to promote arginase activity or expression of YM-1 or Retnla, markers of AAMΦ. Furthermore, macrophages have low/no basal expression of ST2. This suggested that alternative activation of macrophages may involve an IL-33–responsive third-party cell. Because mast cells have the highest expression of ST2 relative to other leukocytes, we focused on this cell type. Coculture experiments showed that IL-33–stimulated mast cells polarized AAMΦ through production of soluble factors. IL-33–stimulated mast cells produced a range of cytokines, including IL-6 and IL-13. Mast cell–derived IL-13 was required for induction of AAMΦ, whereas mast cell–derived IL-6 enhanced macrophage responsiveness to IL-13 via upregulation of the IL-4Rα receptor. Furthermore, we found that AAMΦ polarized by IL-33–stimulated mast cells could suppress proliferation and IL-17 and IFN-γ production by T cells. Finally, we show that AAMΦ polarized by IL-33–stimulated mast cells attenuated the encephalitogenic function of T cells in the experimental autoimmune encephalomyelitis model. Our findings reveal that IL-33 can promote immunosuppressive responses by polarizing AAMΦ via mast cell–derived IL-6 and IL-13.
Analysis of Support for Parents in Raising Children with Dyslexia

The parents of children with dyslexia often experience more parenting stress and depressive symptoms compared to other parents. Studies have shown that supporting and encouraging such parents help in reducing their frustrations, fear, anger, and low self-esteem towards their children. The purpose of this study was to identify and examine the different types of support needed by the parents of children with dyslexia and to explore the relationships between the required support with the parents’ marital status. Fifty questionnaires were distributed to the parents of children with dyslexia and analyzed. The findings showed that the type of support needed for parents of children with dyslexia could be grouped into social, peer-to-peer, financial, and government support. Furthermore, the analysis indicated that there were no significant differences between the social (p = 0.4014), peer-to-peer (p = 0.5020), and government (p = 0.7121) support with parents’ marital status. However, based on one-way ANOVA analysis, there was a significant difference found between the parents’ marital status and financial support (p = 0.0241). Accordingly, it is anticipated that the implication of this research could be used as a guide and a reference for supporting and encouraging parents of children with dyslexia and other learning disabilities.

Preparation of PP-g-(AA-MAH) Fibers Using Suspension Grafting and Melt-blown Spinning and Its Adsorption for Aniline in Wastewater

This paper uses polypropylene (PP) as the matrix and acrylic acid (AA) and maleic anhydride (MAH) as functional monomers to prepare PP-g-(AA-MAH) fibers by suspension grafting and melt-blown spinning technology that are easy to industrially scale-up. The fibers can be used to adsorb aniline from wastewaters. Results showed that the grafting ratio reached the maximum of 12.47%. The corresponding optimal conditions were grafting time of 3h, AA : MAH = 0.75, total monomer content of 55%, benzoyl peroxide 1.4%, xylene concentration of 6 mL/g PP, and deionized water content of 8 mL/g PP. Owing to its good fluidity and thermal stability, the product of suspension grafting can be used for melt-blown spinning. Infrared spectroscopic and nuclear magnetic resonance spectroscopic analyses indicated that AA and MAH were successfully grafted onto PP fibers. After grafting, the hydrophilicity of PP-g-(AA-MAH) fiber increased. Therefore, it had higher adsorptivity for aniline and the adsorption capacity could reach 42.2 mg/g at 45 min. Moreover, the PP-g-(AA-MAH) fibers showed good regeneration performance.
Petrophysical Characterization of a Clastic Reservoir in the Middle Magdalena Valley Basin in Colombia Using Artificial Neural Networks and Seismic Attributes

We apply instantaneous seismic attributes to a stacked P-wave reflected seismic section in the Tenerife field located in the Middle Magdalena Valley Basin (MMVB) in Colombia to estimate effective porosity (φe), water saturation (SW), density () and volume of clay (Vclay) at the seismic scale. The well logs and the seismic attributes associated with the seismic trace closer to one of the available wells is the information used to train some multi-layered Artificial Neural Networks (ANN). We perform data analysis via the Gamma test, a mathematically nonparametric nonlinear smooth modeling tool, to choose the best input combination of seismic attributes to train an artificial neural network (ANN) for estimating porosity, density, water saturation and volume of clay. Once the ANN’s are trained, these are applied to predict these parameters along the seismic line. This is a significant result that shows for the first time a petrophysical characterization of this field at seismic scale. From the continuous estimations of volume of clay we distinguish two facies: sands and shales, and these estimations confirm the production of the Mugrosa C-Sands zone and we draw brown clay that correlates with the high amplitude attributes and the yellow sand correlates with the low amplitude attributes.
Analysis of geotechnical data and ambient noise records to assess site response in Viña del Mar (Chile)

Historical and recent Chilean earthquakes (1906, 1960, 1985, 2010) showed similar building damage distribution in Viña del Mar city related to ground conditions and building height A detailed analysis of 122 geotechnical reports has allowed us to obtain their geotechnical parameters and the VS surface ground structure (calculated from NSPT data) up to a depth of 30 m in 62 of these sites. The site predominant period (Tp) was estimated from ambient noise records (with the HVSR technique) in 84 points regularly spaced (∆ ~200 m). The highest values (Tp > 0.8 s) were found nearby the Marga-Marga fault trace, and gradually decrease on both sides up to 0.4 s close hill zones, being less than 0.2 s at the hills. Two estimates of the basement depth (VS> 800 m/s) from the VS(z) and H/V observed curves show similar results: depth > 60-70 m in onethird of the plain area, reaching 120 m in the center of the basin. The spectral amplification obtained in 12 representative sites by computing the 1-D response of the shallow Vs structure exceeds a factor of 4 in the area with greater thickness and is greater than 3 in the remaining area for the corresponding key periods.
Development of BIMSTEC Free Trade Area for Thailand in Indo-Pacific

To develop a policy for creation of economic value and utilise the development of Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) free trade area for Thailand, two research tools are adopted in this article. The first one is based on the Global Trade Analysis Project (GTAP) model, adopted as a tool to explore quantitative impacts from the implementation of free trade area. Due to the limitations of the model, however, we have adopted a complementing qualitative analytical framework to ensure that the research must be as comprehensive as possible in every aspect. The qualitative analytical framework chosen in this article is called PEST analysis. Having completed field research, in-depth interviews, focus group meetings and model studies, this article concludes that BIMSTEC is a large-scale market with high purchasing power and growth rate as well as a great source of vast natural and human resources. It is situated not far from Thailand, and at the same time, its social and cultural conditions are very close to those of Thailand’s. It concludes that a stronger BIMSTEC is an essential foundation of Indo-Pacific. JEL Codes: F13, F 15
Intelligent UAV Deployment for a Disaster-Resilient Wireless Network

Deployment of unmanned aerial vehicles (UAVs) as aerial base stations (ABSs) has been considered to be a feasible solution to provide network coverage in scenarios where the conventional terrestrial network is overloaded or inaccessible due to an emergency situation. This article studies the problem of optimal placement of the UAVs as ABSs to enable network connectivity for the users in such a scenario. The main contributions of this work include a less complex approach to optimally position the UAVs and to assign user equipment (UE) to each ABS, such that the total spectral efficiency (TSE) of the network is maximized, while maintaining a minimum QoS requirement for the UEs. The main advantage of the proposed approach is that it only requires the knowledge of UE and ABS locations and statistical channel state information. The optimal 2-dimensional (2D) positions of the ABSs and the UE assignments are found using K-means clustering and a stable marriage approach, considering the characteristics of the air-to-ground propagation channels, the impact of co-channel interference from other ABSs, and the energy constraints of the ABSs. Two approaches are proposed to find the optimal altitudes of the ABSs, using search space constrained exhaustive search and particle swarm optimization (PSO). The numerical results show that the PSO-based approach results in higher TSE compared to the exhaustive search-based approach in dense networks, consuming similar amount of energy for ABS movements. Both approaches lead up to approximately 8-fold energy savings compared to ABS placement using naive exhaustive search.
Studying Car-Following Dynamics on the Basis of the HighD Dataset

A large-scale naturalistic vehicle trajectory dataset from German highways, highD, was used to investigate the car-following behavior of individual drivers. These data include trajectories of 110,000 vehicles recorded for a duration of 16.5 h. Solving a nonlinear optimization problem, the intelligent driver model and the optimal velocity model with two leaders in interaction were calibrated by minimizing the deviations between the observed and simulated gaps when following the prescribed leading vehicle. The obtained calibration errors ranged between 5.2% and 6.9%, which were slightly lower than previous findings. This was explained by the shorter highD trajectories, predominantly free-flow traffic, and the good precision metrics of this dataset. The optimal velocity model with multivehicle anticipation resulted in lower calibration errors. This confirmed that natural drivers take into account several leading vehicles ahead. The ratio between interdriver and intradriver variability was investigated by performing global and platoon calibrations. Intradriver variation accounted for a larger portion of the calibration errors than interdriver variation. We analyzed the acceleration time-series of the natural highD and artificial drivers using simulations of two car-following models. A new cumulative measure, proportional to the energy of the follower’s position time-series curve, was calculated both for natural and modeled drivers. Human drivers had higher energy and demonstrated more acceleration fluctuations, sometimes behaving irrationally. In contrast, artificial drivers followed the logical rules incorporated in the model, resulting in a smoother acceleration profile. This led to less fuel consumption and gas emissions.

The Issue on eTravel Business: The Impact of Poor Digital Media Design – A Case of Thailand

-This research investigates the cause of revenue deceleration in eTravel in Thailand, about the design of digital media. eTravel involves the purchasing activities of customers, for example in online travel service booking and online ticketing. These services are provided by businesses with an online presence, known as eTravel service providers. The quantitative research approach determines the relationship between satisfaction factors in digital media design and conversion. The reasons for failure in eTravel conversion are presented as association rules. The research results are used as inputs for developing digital media design guidelines-for example, in recommendations for website design to engage more customers and result in conversions. By applying the guidelines on digital media design, the local eTravel service provider can successfully increase eTravel revenue. In this study, eTravel increased in revenue by 42.50% on average, compared to the same month in the previous year. This confirms the applicability of the proposed guidelines.
Smallholder orange farmer access to markets in Uganda

Orange (Citrus sinensis L.) is a major dietary component globally, responsible for supplying nutrients and phytochemicals of biological and health influence such as minerals, vitamins, fiber, flavonoids, limonoids, and carotenoids and antioxidant. It accounts for more than 50% of the citrus fruits produced world-over. It is a popular fruit in sub-Saharan Africa, though its level of consumption per capita is by global standards very low. In Uganda, orange production is mostly concentrated in eastern and northern parts; mostly grown by small holder farmers who are plagued by a milliard of production and marketing constraints. The objective of this study was to evaluate the effect of institutional, infrastructural and socio-economic factors on smallholder access to orange markets in Uganda. The study was conducted in Kaberamaido, Kumi and Soroti Districts in eastern Uganda, using cross sectional data, during 2011-2012. Probit model results showed that the key institutional factor that affected smallholder access to markets was institutional belonging; the infrastructural factors entailed ownership of mobile phone and location of household; while age of household head, household size and output price constituted the socio-economic factors. Mobile phone, household size and age of household head elicited the highest effect on the probability for smallholder market access, and the magnitude of effect is shown by flexibilities of 0.5, -0.06 and 0.02, respectively. Tobit model estimates showed that market information, and household location constituted institutional and infrastructural factors affecting market access, respectively; while age of trees, output, output price and occupation of household head constituted the socio-economic factors. The critical factors that affect the extent of market access include location, market information, primary occupation of household head and quantity of output as shown by flexibilities of -0.6, 0.5, 0.5, and 0.03, respectively. Based on the Probit and Tobit model estimates, market information, mobile phone and quantity of outputs constitute critical institutional, infrastructural and socio-economic factors that affect smallholder market access. Therefore, opportunity for unlocking the potential for smallholders to access orange markets exists in boosting the level of output and facilitating linkage to markets. Key words: Citrus sinensis, infrastructural, institutional
Loss Analysis of Grid Connected Solar PV System : A Review

Solar energy is becoming an important source of energy all over the World and especially in India. Very few solar plants have been installed in India so far, and therefore no historical experience available. It is important to investigate the performance of solar power plants. Knowledge about the performance of solar power plants will result in correct investment decisions. In this paper, we discuss the various factors contributing to the performance of solar power plants, such as radiation, temperature and other climatic conditions, design, inverter efficiency and degradation due to aging. In this paper, review of a grid-connected photovoltaic system is presented with its performance parameter. The performance ratio and the various power losses (solar irradiation, different type of module loss, temperature, Module soiling, AC and DC losses, cable and wiring loss etc.) are examined. Also examined the performance of plant in terms of different type of plant running losses like generation loss due to grid unavailability system breakdown, inverter breakdown.

A simple model for the temperature dependence of the Fowler- Nordheim carrier tunnelling current through the oxide in a metal-oxide-semiconductor device in accumulation or inversion

Dr. Ravi Kumar Chanana Self-Employed Independent Researcher Corresponding author: Dr. Ravi Kumar Chanana __________________________________________________________________________________________ Abstract: A simple model for the temperature dependence of the Fowler-Nordheim carrier tunnelling current through the silicon dioxide in a metal-oxide-semiconductor device in accumulation or inversion is proposed. The model is based on the premise that the average energy of the electrons in the oxide change exponentially because the number of electrons in the oxide change exponentially due to ionization at high fields giving a multiplication factor for the carrier tunnelling current. The electron barrier heights or the conduction band offsets in a 4H-SiC MOS device have been computed from the equation for the model at temperatures ranging from 10 K to 698 K. These have been compared with the experimentally observed barrier heights on commercial n-channel 4H-SiC MOSFETs in inversion. The change in barrier height with temperature is found to be -2.9 x 10 -4 eV/K from the model and -6.86 x 10 -4 eV/K from the commercial MOSFETs. The difference is attributed to the inaccurate calculation of the oxide field in the commercial MOSFETs. Similar behaviour is observed in a Si MOS device of an earlier study.
