A Cross-source Scheduling Method for Heterogeneous Data in Cloud Environment

To address the time-consuming problem of scheduling the transmission of heterogeneous data across sources in cloud computing, many existing scheduling methods are implemented by heuristic algorithms, which usually cause load imbalance and low throughput and acceleration. Therefore, this paper proposes a cross-source scheduling method for heterogeneous data in a cloud environment, which carries out data prefetching before the actual scheduling, greatly reducing the computation amount during scheduling and thus the scheduling resource overhead. Then, all variables are updated, the quality of the heterogeneous data cross-source sub-stream to be scheduled is arranged, and it is regarded as the weight of the sub-stream data, the best quality sub-stream data among the heterogeneous multi-source sub-stream data is selected in the scheduling window each time for scheduling transmission, and the processing of all data sub-streams on paper is finished. The experimental results show that the method proposed in this paper is capable of cross-source scheduling of heterogeneous data in a cloud environment with high load balancing, throughput and acceleration ratios.
Subcarrier Nulling: Fair and Efficient Coexistence of LTE/WiFi in Unlicensed Band

With the explosive growth of data traffic and the number of terminals in wireless networks, the scarcity contradiction of wireless spectrum resources is increasing. Deploying Long Term Evolution(LTE) technology to 5GHz unlicensed band of WiFi is an effective way to greatly improve spectrum efficiency. The core technology of existing broadband WiFi technology adopts traditional CSMA/CA mechanism, which has the problems of occupying WiFi channel resources for a long time, not fully utilizing network resources and blocking broadband channels when LTE accesses WiFi channels. In this paper, an optimization scheme of LTE and WiFi coexistence structure based on subcarrier nulling is proposed. The working mechanism of this scheme is as follows: the nodes of broadband WiFi perform spectrum sensing at subcarrier granularity. When detecting that there are LTE nodes working in the same frequency band around, only the subcarriers that do not overlap with the channels of the LTE nodes are used for communication, and the 20MHz occupied by LTE is set to null, so as to achieve the purpose of coexistence. Simulation results show that the optimization scheme based on subcarrier nulling can effectively improve the performance of coexistence system, and make the fairness up to more than 90%, which provides an realizable scheme for the problems existing in the coexistence structure of LTE and WiFi.
On the hindered settling of suspensions of mud and mud-sand mixtures

Highly concentrated suspensions are present in many natural environments. When the concentration becomes large enough, particles start to interfere with each other and their settling velocity reduces. This is called hindered settling. As a result of the reduced settling velocity, particles remain in the water column for a longer time and the light penetration through the water column is reduced. This affects primary production, which stands at the base of the food chain. This research deals with the hindered settling of suspensions of mud and mud-sand mixtures. A combination of laboratory experiments, mathematical theories and modelling was used to come to a better understanding and prediction of the settling velocity of the different fractions within these suspensions and the interaction between the fractions. The combination of techniques proved to be successful. This research has increased the understanding on the behaviour of highly concentrated mud and mud-sand mixtures. As a result, questions that relate to increased turbidity levels and environmental impact might be answered better.
Holistic Approach for Design of Minimum Water Networks Using the Mixed Integer Linear Programming (MILP) Technique

Minimum fresh water consumption and wastewater generation in a facility can be achieved when all options for water minimization including source elimination, reduction, reuse/recycle, outsourcing, and regeneration have been considered. This work presents the development of a new generic mixed integer linear programming (MILP) model to holistically minimize fresh water consumption and wastewater generation for systems involving multiple contaminants where the various options for water minimization are simultaneously considered in order to ultimately generate a minimum water utilization network. The MILP model proposed in this work can be used to simultaneously generate the minimum water targets and design the minimum water network for global water-using operations for buildings and industry. This work also includes cases where fresh water concentrations for all contaminants are assumed to be either zero or non-zero. The approach has been successfully implemented in case studies involving an urban building (Sultan Ismail Mosque, UTM) and a manufacturing plant (a chlor-alkali plant).
Functional genome Annotation in Bacterial infections: A Review

: Functional annotation provides the information of gene about its biological identity and various types of molecular function and biological role like sub-cellular location and its expression. It functions by attaching biological information of gene and protein. The primary level of annotation is performed by using Basic logical Alignment Tool (BLAST) for finding similarity and then annotation of genes are performed based on this information. The function of gene and variation in gene functioning can be understand by the elucidation of genome annotation. Ensemble annotation tool gives fast computational annotation in eukaryotes derived from mRNA, RNAseq. The two groups HAVANA and RefSeq (human and vertebrate analysis and annotation and Reference Sequence respectively) give rise to wide genome manual transcript annotation and are the finest computational method which recognize 70% of manual annotated loci. The prokaryotic genomes are involved in various genome projects with utilization of Next Generation Sequencing (NGS) it leads to decrease in time and money consumption. Bacterial genome annotation is done by the help of annotation pipeline it provides NCBI resource of content including Nucleotide, Protein, BLAST by the use of software GLIMMER which helps in identification of long protein coding gene mainly in bacteria. A novel bacteriophage Abp2 infects the bacteria Acinetobacter baumannii a multi drug resistance (MDR). The genome annotation of this phage reveals that it is a circular DNA with 85 open reading frame (ORF) with putative genes in which 41 known function and 47 unknown function protein were recognized. This review article summarizes genome annotation function and structural aspects.
Bioactive Compounds and Biochemical and Antioxidant Properties of Selected Minor Indigenous Fruits in Bangladesh

Minor fruits are a potential source of antinutrients, but there is no complete primary data source in the Bangladeshi context. Therefore, the present study was undertaken to acquire documentation for a database of the composition of selected minor fruits. The total phenolic (TPH), vitamin C, total carotene, and ß-carotene contents and antioxidant activity of selected minor fruits were determined by 1,1-diphenyl-2picryl hydrazyl (DPPH) scavenging and reducing power assays (RPA). Phenolic compounds were assessed using high-performance liquid chromatography coupled with a photodiode array detector and autosampler. Results revealed that minor fruits contain different phytochemicals, particularly TPH, ascorbic acid, total flavonoid (TF), ß-carotene, total carotenoid (TC), and total anthocyanin content (TAC); values ranged, respectively, 0.23-176.50 mg GAE/g, 16.67-664.92 mg/100 g, 2.26-150.02 mg QE/100 g, 1.41-6897.57 µg/100 g, 1.26-98.24 mg/100 g and 1.15-47.46 mg/100 g. In the parameters antioxidant activity, total antioxidant capacity, DPPH, reducing power capacity (RPC), ferric reducing antioxidant power (FRAP), metal chelating capacity (MCC), nitric oxide (NO), and free radical scavenging activity, IC50 ranged 0.01-278.24 µg of ascorbic acid/mg of extract, 39.70-250.00%, 3.21-634.00%, 0.02-1817.88 µM Fe2SO4/100g, 22.29-210.43%, 0.02-70.50%, and 4.98-856.70 µg/g, respectively. Among the identified and quantified phenolic acids, leading examples were gallic acid (279.06 mg/100 g), vanilic acid (43.77 mg/100 g), Þ-courmaric acid (178.96 mg/100 g), ferulic acid (20.44 mg/100 g), and lutein (91.13 µg/100 g) in aonla, day fruit, elephant apple, and bilimbi. Moreover, all selected minor fruits are rich sources of bioactive, biochemical, and antioxidant compounds with potential for use in therapeutic applications.
Assessment of the ahyI gene affected biofilm formation, motility, extracellular virulence and the pathogenicity in a fish model of infection

Aeromonas hydrophila is a pathogen that causes disease in a wide range of homeothermic and poikilothermic hosts due to its multifactorial virulence. The production of many of these virulence determinants is associated with high cell density, a phenomenon that might be regulated by quorum sensing. The quorum sensing system regulates the expression of several virulence factors in a wide variety of pathogenic bacteria. To investigate the pathogenic role of quorum sensing system in A. hydrophila, We constructed an ahyI mutant strain of a fishclinical isolate YJ-1, named YJ-1∆AhyI. Compared with the wild-type strain, the ahyI mutant strain exhibited a significant decrease of total extracellular virulent activity, and decreased in biofilm formation, intraperitoneal LD50 of YJ-1∆AhyI were more than 10 9 CFU, about 10 4 times higher than the parent strain. These results suggest that A. hydrophila is able to regulate its extracellular virulent factors and biofilm formation by quorum sensing systems, and indicate that disruption of quorum sensing could be a good alternative strategy to combat infections caused by A. hydrophila.
Sequential Reporting Bias

Firms with correlated fundamentals often issue reports sequentially, leading to information spillovers. The theoretical literature has investigated multi-firm reporting, but only when firms report simultaneously. We examine the implications of sequential reporting, where firms aim to maximize their market price and can manipulate their reports. Our model demonstrates that the introduction of sequentiality in the presence of information spillovers significantly alters the biasing behavior of firms and the resulting informational environment relative to simultaneous reporting. In particular, a lead firm always manipulates more when reports are issued sequentially than under simultaneous reporting. Interestingly, this occurs because follower firms, who benefit from information spillovers, place less weight on their own private information when issuing a report. This information loss leads the market to place greater weight on the leader's report, which increases the incentive of the lead manager to manipulate her report. Moreover, the information loss from sequentiality leads to less efficient and less volatile prices. Additionally, we find that stronger correlation in firm fundamentals can amplify the lead firm's incentive for manipulation under sequentiality, in contrast to simultaneous reporting. We offer additional results regarding, for example, market response coefficients, and provide a number of empirical implications.
Arbuscular Mycorrhizal Fungi Alleviate Arsenic Toxicity in Sophora Viciifolia Hance. by Improving The Growth, Photosynthesis, Reactive Oxygen Species and Gene Expression of Phytochelatin Synthase

Arbuscular mycorrhizal fungi (AMF) can protect host plants against arsenic (As) toxicity. However, knowledge on the response of woody leguminous under As stress is limited so far. In this study, Sophora viciifolia seedlings were inoculated with/without AMF Rhizophagus intraradices, and S. viciifolia were grown in three levels (0, 50, and 100 mg As kg−1 soil) of As-polluted soil though the potted experiments. The objective of this study was to investigate the influences of AMF symbiosis on woody leguminous under As stress. Some physiological and biochemical parameters of S. viciifolia, which included the plant growth, photosynthesis, oxidative damage, antioxidant enzyme activities and gene expression of phytochelatins (PCs), were analyzed. The results showed that As toxicity in soils inhibited the AM colonization rate, plant growth, photosynthesis, increased the oxidative damage and antioxidant enzyme activities, and up-regulated the gene expression of SvPCS1 in the leaves and roots of S. viciifolia seedlings. However, compared with non-inoculated S. viciifolia at the same As level, R. intraradices-inoculated S. viciifolia had higher shoot and root dry weight, plant height, root length, photosynthetic rate (Pn), stomatal conductance (gs), transpiration rate (E), maximal photochemical efficiency of PSII photochemistry (Fv/Fm), actual quantum yield (ΦPSII), and photochemical quenching values (qP), as well as lower intercellular CO2 concentration (Ci) and non-photochemical quenching values (NPQ). R. intraradices inoculation inhibited the malondialdehyde (MDA), H2O2, and O2•– concentrations, but improved the activities of antioxidative enzymes (SOD, POD, and CAT) in S. viciifolia leaves and roots. The gene expression of SvPCS1 in the leaves and roots was obviously up-regulated by R. intraradices inoculation. These results demonstrated that R. intraradices inoculation enhanced the As tolerance of S. viciifolia seedlings, owing to the beneficial effects of AMF symbiosis on improving the plant growth, gas exchange, chlorophyll fluorescence, antioxidant enzymes, reactive oxygen species and gene expression of SvPCS1 in S. viciifolia seedlings. R. intraradices is possible to get involved in the defence response of S. viciifolia seedlings against. As toxicity stress. This investigation got more profound insights into As tolerance mechanisms of woody leguminous associated with AMF symbiosis.
GRADES: Gradient Descent for Similarity Caching

A similarity cache can reply to a query for an object with similar objects stored locally. In some applications of similarity caches, queries and objects are naturally represented as points in a continuous space. Examples include 360° videos where user’s head orientation—expressed in spherical coordinates— determines what part of the video needs to be retrieved, and recommendation systems where the objects are embedded in a finite-dimensional space with a distance metric to capture content dissimilarity. Existing similarity caching policies are simple modifications of classic policies like LRU, LFU, and qLRU and ignore the continuous nature of the space where objects are embedded. In this paper, we propose Grades, a new similarity caching policy that uses gradient descent to navigate the continuous space and find the optimal objects to store in the cache. We provide theoretical convergence guarantees and show Grades increases the similarity of the objects served by the cache in both applications mentioned above.
What Is the Evidence for Dietary Supplements Usage for COVID-19 Control and Management ?

In the wake of the COVID-19 pandemic, global medical research has undertaken a relentless quest to unravel the virulence mechanisms of SARS-CoV-2, the innate barriers of host defense, the surveillance of progress toward herd immunity, and the attempts to quickly identify and evaluate novel or alternative coronavirus interventions. This nutrition update highlights the important role of dietary factors in achieving optimum health and also explores possible approaches to augmenting innate host defenses. The potential anti-coronavirus benefits of micronutrients and macronutrients (ie, minerals, vitamins, lipids, proteins and polyphenols) to combat COVID-19 infection through inhibition of viral targets on human cell surface (ie, angiotensinconverting enzyme 2) for docking, entry, and replication and, furthermore, to regulate immune and inflammatory responses (cytokine storm), oxidative stress (redox imbalance), and normal signaling pathways to the reduce health risks among vulnerable populations (ie, elderly) with metabolic disorders (ie, obesity, diabetes, cardiovascular disease, hypertension, asthma) and recovery of patients to normal health are discussed.

BATCH ANALYSIS OF SLURRIES IN ZONE SETTLING REGIME

An integrated model for computing the height variation of the mudline and sediment-suspension interfaces of a slurry exhibiting zone settling behavior is proposed. The model accounts for the dynamic interaction of the two dominant components of a batch test, the settling of solids in the suspension region, and the compression of the material that has already been deposited at the bottom of the cylinder. The settling of solids is modeled by the Kynch theory, while the compression process is represented by a self-weight nonlinear finite strain model. A graphical procedure that involves use of the slurry flux curve in conjunction with the Kynch model is developed to calculate the flux of the solids that settle atop the sediment layer. The equation governing the compression process, which is a nonlinear transient partial differential equation of the parabolic type, is solved numerically by using the finite-element method for the spatial domain, while for the time domain a finite-difference scheme is used. Its solution provides the compaction rate and the velocity of the upward moving liquid that is squeezed out from the sediment layer. The coupling of the two components is accomplished by continuously accounting for the effects of the newly deposited sediment on the thickness of the sediment layer and the attendant release of upward moving liquid and its influence on the settling of solids within the suspension. The validity of the model is illustrated by using data reported in the literature for a mineral clay.
Effects of Composition, Temperature and Purge on the Performance of the Cyclic Adsorption of CO2 and CH4 on Activated Carbon

This paper deals with pressure-swing-adsorption (PSA) experiments for removing CO2 and CH4 from a mixture with an ‘inert’ such as hydrogen or helium. Specific features are quasi cyclic steady-state and no breakthrough of the adsorbed impurity during the adsorption-production step, implying that information has to be taken inside the column, here by a set of temperature measurements. The purpose is to propose an approach for evaluating the effect on the behaviour and performance of different working conditions (feed composition, temperature, conditions of regeneration, adsorbent) under conditions of optimal bed length. We define a new criterion to represent the effective sorption capacity required in adsorption, which we call critical bed fraction (CBF), defined as the fraction of bed length occupied by the temperature and concentration fronts at incipient breakthrough of the less adsorbed component, at cyclic steady-state. The effects of the different parameters on performance (recovery and productivity) may then be expressed and analysed in terms of CBF. Some noteworthy observations are the following: for a given amount of purge, the flow velocity in the purge step may have an optimal value; a relatively high concentration of CH4 may have positive effects on both recovery and productivity when used with a high purge velocity, because it contributes to a better desorption of CO2; the advantages of an adsorbent having a high capacity per unit mass and fast internal kinetics may be offset if the density is low, implying a low capacity per unit volume.

Effect of two different commercially available tea products on salivary pH: A randomized double blinded concurrent parallel study

Background: Many studies have demonstrated the beneficial effect of tea on dental caries. Aim: The aim of the present study was to compare and evaluate the effect of green tea and black tea infusions on salivary pH in caries free and with caries individuals. Settings and Design: Randomized double-blinded concurrent parallel study. Materials and Methods: Forty healthy subjects, aged 18-20 years participated in the study. Commercially available green tea (Tetley Pure Green Tea) and black tea (Tetley Black Tea) were used in the study. The pH of saliva and of the tested tea products was determined with a digital pH meter. pH of whole saliva was measured at baseline and immediately after the intake of product (0), 5, and 10 min later. Data analysis was carried out by Student's t -test and repeated measure ANOVA. Results: In vitro pH determination of infusion showed pH value of green tea (6.27 ± 0.02) was higher compared to black tea (6.13 ± 0.03). Both green and black tea infusion intake led to a statistically significant rise in salivary pH, both in caries-free and with caries groups, which remained above the base salivary pH over the whole period of measurements. Conclusion: The present study demonstrated that after intake of both green and black tea there was an increase in salivary pH both in caries-free and with caries groups. The pH rise was more in green tea intake compared to black tea.
One-Pot Synthesis of Enaminones Using Golds Reagent

Enaminones were efficiently prepared via modification for Gupton method, which depends on carrying out the latter procedure in one step reaction, avoiding the isolation of (3-(dimethylamino)-2-azaprop-2-en-l- ylidene)dimethylammonium chloride (Gold's reagent) (5) which is prepared in situ from cyanuric chloride (4) then it reacts successfully with ketone la-j to produce the enaminones 3a-j in suitable yields. The modified method overcomes the drawbacks of the known methods for preparation of enaminones.
NBER WORKING PAPER SERIES CONSUMPTION COMMITMENTS AND HABIT FORMATION

We analyze the implications of household-level adjustment costs for the dynamics of aggregate consumption. We show that an economy in which agents have “consumption commitments” is approximately equivalent to a habit formation model in which the habit stock is a weighted average of past consumption if idiosyncratic risk is large relative to aggregate risk. Consumption commitments can thus explain the empirical regularity that consumption is excessively sensitive and excessively smooth, findings that are typically attributed to habit formation. Unlike habit formation and other theories, but consistent with empirical evidence, the consumption commitments model predicts that excess sensitivity and smoothness vanish for large shocks. These results suggest that behavior previously attributed to habit formation may be better explained by adjustment costs. We develop additional testable predictions to further distinguish the commitment and habit models and show that the two models have different welfare implications despite generating similar aggregate consumption patterns in many environments.
