Role of Regional Parameters in Inter-annual Variation of Indian Summer Monsoon Rainfall

The Indian summer monsoon affects almost all the facets of life in India. Variability in the onset and duration of monsoon has profound impacts on water resources, human life, agriculture, economics and ecosystems. That is why predictions of the monsoon behavior are eagerly watched by government planners and agronomists. However, every monsoon has its own unique characteristics, which makes it more enigmatic and complex. Predicting the likely physical behavior of the monsoon system and the resulting distribution of rainfall over different parts of India is an extremely challenging task. Sometimes, the necessity of producing long-range forecasts has compelled investigators to develop empirical relationships between different facets of the coupled atmosphere-ocean land system. The present study also presents some empirical evidence of relationships between summer monsoon rainfall and sea-surface temperature over the Indian Ocean. Sea surface temperatures exert significant control over the atmosphere, particularly over the monsoon circulation. The study has identified four pockets in the Indian Ocean, which can be used as potential predictor zones for summer monsoon rainfall (June to September) over India. To achieve this objective, correlation analysis with lags in months was carried out to establish association between the sea surface temperature over the four pockets and summer monsoon rainfall. Strong significant association can be found between the SST of these four pockets and Indian summer monsoon rainfall. The study also reveals a phase-change in the relationship between the sea surface temperature and Indian summer monsoon rainfall, particularly in the recent period.
Low-Cost Metamaterial Loaded Microstrip Antenna for Defense Applications

We have designed a Metamaterial unit-cell for 9 GHz frequency. Periodic structure was used at 4.25 × 4.25 mm with a thickness of 0.35 mm and giving us the 99.99% of absorbance at 9 GHz in simulated results. We have implemented a rectangular microstrip antenna and loaded it with Metamaterial unit-cells which provided improved results. There were results available for reflection coefficient (s11 parameter) at 9 GHz and also helping for the reduction of the Radar Cross Section of an antenna, which reduced more than 20 dB and not affected its directivity and gain.
Generation of Pedestrian Crossing Scenarios Using Ped-Cross Generative Adversarial Network

The safety of vulnerable road users is of paramount importance as transport moves towards fully automated driving. The richness of real-world data required for testing autonomous vehicles is limited and furthermore, available data do not present a fair representation of different scenarios and rare events. Before deploying autonomous vehicles publicly, their abilities must reach a safety threshold, not least with regards to vulnerable road users, such as pedestrians. In this paper, we present a novel Generative Adversarial Networks named the Ped-Cross GAN. Ped-Cross GAN is able to generate crossing sequences of pedestrians in the form of human pose sequences. The Ped-Cross GAN is trained with the Pedestrian Scenario dataset. The novel Pedestrian Scenario dataset, derived from existing datasets, enables training on richer pedestrian scenarios. We demonstrate an example of its use through training and testing the Ped-Cross GAN. The results show that the Ped-Cross GAN is able to generate new crossing scenarios that are of the same distribution from those contained in the Pedestrian Scenario dataset. Having a method with these capabilities is important for the future of transport, as it will allow for the adequate testing of Connected and Autonomous Vehicles on how they correctly perceive the intention of pedestrians crossing the street, ultimately leading to fewer pedestrian casualties on our roads.

Deep-sea wood-boring bivalves (Xylophagaidae) from southeast Australia, with a new species described

ABSTRACT Recent advances in sampling capabilities have enabled some of the first large-scale bathyal and abyssal surveys in Australian waters, allowing new insights into the deep-sea invertebrate fauna of the region. Here we describe Abditoconus investigatoris n. sp. , the first xylophagaid described from Australia in 60 years. Abitoconus investigatoris is characterised by a siphon with distinct proximal and distal portions, with a prominent wrinkled ventral band on the proximal portion. This species was also observed with epizoic ciliates (fam. Vorticellidae), the first known association of ciliates and xylophagaids.
Power flows in multi-junction power supply circuits

The article discusses a methodology that allows for an accurate calculation of the parameters of electrical equipment from the point of view of optimizing the power supply system. Taking into account the characteristics of transients processes makes it possible to select equipment in maximum load modes. Modeling of power flows caused by changes in the load of consumers is carried out on the example of calculating the power supply circuit of five junctions. It is shown that it is possible to change the direction of flows of transmitted electric power at certain ratios of parameters in individual elements of the circuit. Purpose of research: to show the possibility of changing the picture of the transmitted capacities by the elements of the power supply system, depending on consumer loads.
Adenocarcinoma of the sigmoid colon in familial adenomatous polyposis syndrome: A case report

Familial adenomatous polyposis (FAP) is an autosomal dominant inherited syndrome characterized by the development of numerous adenomatous polyps in the colon and rectum. A germline mutation in the APC gene (adenomatous polyposis coli) present on chromosome 5q21 is the molecular level defect causing this syndrome. In this case series report, we report two cases of FAP from a single family of 10 members which included parents, four female siblings, and four male siblings. Apart from index cases, the rest of the family members detected to have polyps on colonoscopic evaluation. Literature review, data regarding timely surgery, surveillance, and chemoprevention are discussed. The FAP phenotype determines the type of treatment. In severe polyposis, proctocolectomy with ileoanal anastomosis is the optimal method for minimizing cancer development risk. Genetic counselling should guide genetic testing and considerations of colectomy. This case report advocates complete rectal removal, especially in cases of poor patient compliance.

Event-Based Adaptive Fuzzy Fixed-Time Secure Control for Nonlinear CPSs Against Unknown False Data Injection and Backlash-Like Hysteresis

This article investigates the event-triggered adaptive fuzzy fixed-time secure control problem for a class of nonlinear cyber-physical systems subject to unknown deception attacks and backlashlike hysteresis. Based on an improved fractional-order command filtered backstepping method, fuzzy approximation technique, and Nussbaum gain technique, a novel adaptive practical fixed-time secure control scheme is proposed. Theoretical analyses prove that the fixed-time stability of the resulting control system and boundedness of all signals in the closed-loop system can be guaranteed by using the presented resilient controller. Especially, the given convergence time is independent of the initial states of the system and better system performance consisting of higher control accuracy and faster convergence rate can be ensured. Finally, a chemical reaction system is carried out to show the validity and superiority of the developed secure control scheme.
Assessment of albumin and aspartate levels as a simple indicator of the efficacy of cryopreservation

Background: The process of hepatocytes cryopreservation is standardised by most of the laboratories. However there is a variation with respect to the Protocols, media and equipments used amongst the laboratories. Similarly, the tests available to evaluate the efficacy also varies. They are expensive and sometimes might not measure the parameter required for a particular research study. Hence we propose a methodology to study the few basic parameters like cell viability, synthetic function of the cell and cell stability. We have also used a simple percentile calculation to know the efficacy of cryopreservation. This shall help in functional validation of the cell after cryopreservation. The same can also be used to compare the quality of hepatocytes between different batches. The objective of the study was to characterisation of the cells to determine the efficacy of cryopreservation. Methods: Two step collagen isolation method was used to isolate the hepatocytes. Initial cell viability was calculated. A sample of cells were taken for characterisation and the remaining cells cryopreserved. The sample cells were divided into two batches one for pre cryopreservation culture and the other for post cryopreservation. The pre cryopreservation culture was done on monolayer using collagen coated 6 well plate. The other sample was placed in the cryovials for cryopreservation for 1week. After 1 week the cryopreserved cells were thawed and the post cryopreservation viability calculated, followed by post cryopreservation culture. During the process of culture (both pre cryopreservation and post cryopreservation) for 5days Albumin was measured daily and average calculated, peak Aspartate (AST) at 24 hours was recorded. The percentile difference of the obtained values between the pre cryopreservation and post cryopreservation culture was calculated. Results: A total of 12 specimen were enrolled for the study. The mean pre cryopreservation viability of the cells was 66.58%. The post cryopreservation, viability of the cells was 36.43%. The mean difference was -30.170%. The pre cryopreservation albumin values had a mean of 150ng/ml. The post cryopreservation albumin values had a mean of 135.83ng/ml. The mean difference was -14.170ng/ml. The pre cryopreservation peak Aspartate values had a mean of 234.17 IU/ml. The post cryopreservation peak aspartate values had a mean of 230 IU/ml. The mean difference was -4.176 IU/ml. Conclusions: This simple method can validate the cells after cryopreservation by measurement of cell viability, synthetic function of the cell and cell stability.

Assessment of the contribution of hazardous air pollutants from nigeria’s petroleum refineries to ambient air quality. Part 1

Abstract This study investigated the contribution of anthropogenic emission of benzene from petroleum refineries to the Nigerian’s ambient air quality with the view of understanding the impact of petroleum production facilities on host airshed. The Activities of the four existing and 22 proposed petroleum refineries in Nigeria were obtained from the Department of Petroleum Resources and these were combined with emission factors of different units at the refineries to estimate benzene emissions. No-control-measure option (worst case scenario) was assumed because of lack of information on control efficiency of the refineries. The study revealed that two of the existing refineries in one of the oil-producing cities in Nigeria released a total of 10.01 × 1011 tons/year of benzene into the ambient air of the city, apart from additional 2.35 × 1013 tons/year anticipated to be released from three of the proposed refineries into the ambient air of the same host community. If operated at full capacity, the estimated benzene emission from the four existing refineries stood at 5.50 × 1013 tons/year while the 22 proposed refineries have the capacity of releasing additional 16.73 × 1013 ton/year. On the overall, the contribution of benzene from refineries on yearly basis to Nigerian airshed was estimated to be 22.24 × 1013 tons. These concentrations if not checked could lead to devastating environmental issues. Some mitigating measures were suggested to control and subsequently abate benzene emission from these refineries.
Differential Accumulation of Metabolites in Suaeda Species Provides New Insights into Abiotic Stress Tolerance in C4-Halophytic Species in Elevated CO2 Conditions

Halophytic plants can adapt to grow and thrive in highly saline conditions. Suaeda species are annual halophytes with high salt tolerance and are most suitable in the restoration of salinized or contaminated saline land and as food, forage, medicine, and bioenergy. In this study, we comprehensively analyzed the different metabolic responses of Suaeda species under salt and drought stress at ambient and elevated CO2 conditions. Seedlings of Suaeda species were treated with 500 mM NaCl and 5% of polyethylene glycol under elevated CO2 stress conditions for 24 h. Then, widely untargeted metabolites were detected by gas chromatography–mass spectrometry. Different metabolites involved in amino acid metabolism, glycolysis, photorespiration, and tricarboxylic acid cycle were quantitatively determined after stress treatments. A total of 61 primary metabolites were annotated. Different treatments increased the contents of certain metabolites, such as amino acids, sugars, and organic acids, as well as some antioxidants, such as quininic acid, kaempferol, and melatonin. These substances may be correlated with osmotic tolerance, increased antioxidant activity, and medical and nutritional value in the species. This study suggests that various metabolites differentially accumulated in C4Suaeda species under varying stress conditions. Furthermore, this work provides new insights into the key secondary metabolite pathway involved in stress tolerance.
Librarians’ development as teachers

This article reports on findings of an online survey of teacher librarians about their instructional work, approaches, and roles and how these aspects of their teaching have changed over time. Academic librarians who had at least one year of library teaching experience and who had been actively involved in library instruction within the past two years completed the online survey. Participants were asked a series of questions, the majority of which were open-ended, about the types of instruction-related activities in which they presently and previously engaged, if/how their views of their instructional work and their instructional roles had changed over time, what experiences had been particularly influential in their teaching, and if they identified as teachers. The responses were analyzed through manual textual coding, through which emerging themes and variations in participants’ responses were identified. These findings provide further insight into academic librarians’ ongoing teacher development and their experiences as teaching librarians. Fuller understandings of this development and experiences can inform professional development and communities of practice in which librarians foster a sense of agency, confidence, responsiveness, and purpose in their teaching, cultivate and sustain meaningful teaching practices, and prevent burnout.
The Wear Rate and Survivorship in Total Hip Arthroplasty Using a Third-generation Ceramic Head on a Conventional Polyethylene Liner: A Minimum of 15-year Follow-up

Purpose The purpose of this study was to evaluate the wear and survival rates of third-generation ceramic heads on a conventional ultra-high molecular weight polyethylene liner. Materials and Methods A total of 160 hips (147 patients with a mean age of 55.9 years) who underwent total hip arthroplasty using the third-generation ceramic head on a conventional polyethylene liner from March 1998 to August 2003 were reviewed retrospectively. Evaluation of the wear rate for 56 hips (49 patients) followed-up for at least 15 years was performed using the PolyWare program version 8 (Draftware Developers, USA). The Kaplan–Meier survivorship was also evaluated. Results Linear wear and volumetric wear rates were 0.11±0.47 mm/year and 32.75±24.50 mm3/year, respectively. Nine revisions were performed during the follow-up period because of cup or stem loosening. The Kaplan–Meier survival rate, using cup revision or total revision total hip arthroplasty (THA) as the endpoint of analysis, was 93.7% at 15 years and 73.6% at 20 years. Conclusion Because all revisions were performed between 15 and 20 years in our study, surgeons should pay greater attention to patients who underwent THA with ceramic-on-polyethylene bearing from 15 years postoperatively. Contemporary alumina ceramic on highly cross-linked polyethylene could certainly be a good alternative bearing couple providing better longevity.
Adaptive containment control for nonlinear strict-feedback multi-agent systems with dynamic leaders

This paper focuses on the adaptive containment control problem for nonlinear strict-feedback multi-agent systems with dynamic leaders. An adaptive controller is constructed by backstepping control, first-order filters and compensating signals. The ``explosion of complexity" phenomenon is avoided by introducing first-order filters in traditional backstepping control, and filter errors are handled with compensating signals. All adaptive laws are accumulated to the last step by using tuning functions. The whole control design method is divided into two parts. One is to design adaptive tracking control for dynamic leaders. The other is to design adaptive containment control for followers. Through the proposed control method, the closed-loop system is stable, and all followers can converge to the convex hull built by the leaders. The simulation studies can confirm the effectiveness of the proposed control method.

Accelerated senescence and nitrogen remobilization in flag leaves enhance nitrogen use efficiency in soft red winter wheat

ABSTRACT Wheat (Triticum aestivum L.) production requires a large amount of nitrogen (N) supply because growers aim to achieve high grain yield and appropriate grain protein content simultaneously. A comprehensive understanding of the mechanisms that underpin efficient N usage at limited N in wheat can facilitate the development of new N-saving varieties in this major crop. Here, we performed comparative analysis of flag leaf responses to N availability in soft red winter wheat with contrasting N use efficiency (NUE); VA08MAS-369 (high NUE) and VA07W-415 (low NUE). This study demonstrated that accelerated senescence along with enhanced breakdown of protein and starch in flag leaves was correlated with higher grain yield, NUE for grain yield, and NUE for grain protein under N limitation. The more dramatic reductions in flag leaf N compounds and carbohydrate reserves in VA08MAS-369 were linked with significantly elevated expression of genes and enzymes associated with these metabolic pathways in this high NUE genotype. Consistent with the gene expression data, nitrate reductase, glutamine synthetase, and NAD-dependent glutamate dehydrogenase activities were highly induced under limited N in VA08MAS-369. It was previously reported that accelerated senescence contributes to increased grain protein content in wheat under regular N supply. This study provides molecular and physiological evidence that vigorous senescence and N remobilization also benefit grain yield under N deprivation. Graphical abstract
