An Efficient Stock Market Trend Prediction Using the Real-Time Stock Technical Data and Stock Social Media Data

: Stock market trend prediction is one of the major issues which have been problematic to both financial analysts and scientific research on real-time streaming `data. Also, forecasting stock market returns based on the technical data is difficult due to noise in the data and mixed data types. As the size of stock technical tools and techniques are increasing along with stock news data, it becomes more difficult to analyze and predict the market trend based on the historical market data. Therefore, it is very challenging task to research institutes and financial brokerages for data analysis and market trend prediction. Since, financial data is unstructured by nature and it is difficult to find an essential feature for intraday bullish and bearish trend prediction. In this work, a new stock technical indicator based non-linear SVM model is designed and implemented on the real-time stock market data for trend prediction. In this model, a novel stock technical data transformation technique, stock technical and text feature extraction method and non-linear SVM classification algorithm are proposed to predict the stock trend on daily and weekly basis. Experimental results have shown that the proposed stock market trend prediction approach has 7% of computational runtime (ms) and an average stock prediction accuracy of 10% as compared to the existing stock market trend prediction models.
Quality characteristics of fermented soybean products produced by lactic acid bacteria isolated from traditional soybean paste

This study evaluated quality characteristics of soybean fermented by selected lactic acid bacteria, which were the enzyme strains with high antimicrobial activities isolated from traditionally prepared soybean paste. We determined total aerobic and lactic acid bacteria counts, protease and amylase activities, reducing sugar and amino-type nitrogen contents, and the amounts of amino acids, organic acids, and aroma-compounds. The total aerobic bacteria counts in soybean fermented with strain I13 (7.75×10 CFU/mL) were the highest among all the strains analyzed. Lactic acid bacteria numbers were 2.85×10 to 4.35×10 CFU/mL in soybean fermented with isolates. Amylase and protease activities of the JSB22 sample were the highest among all sample. Reducing sugar and amino-type nitrogen contents of soybean fermented with JSB22 (1.23%, 94.52 mg%) were highest. Total amino acid content of the samples was 15.88-17.62%, and glutamic acid, aspartic acid, leucine, lysine, and arginine were the major amino acids. Lactic acid (0.82-3.65 g/100 g), oxalic acid (22.74-63.57 mg/100 g), and fumaric acid (2.88-6.33 mg/100 g) were predominant organic acids. A total of 39 volatile aroma-compounds were identified, including 2 esters, 5 ketones, 7 alcohols, 14 hydrocarbons, 2 heterocyclic compounds, 4 acids, and 5 miscellaneous compounds. These results represent useful information for the development of a starter (single or complex) and will be used for production of functional fermented soybean foods.
Reflective photonic hook achieved by a dielectric-coated concave hemicylindrical mirror

In this study, we propose a new design of a dielectric-coated concave hemicylindrical mirror for efficient generation of a reflective photonic hook (PH). Numerical approaches based on the finite-difference time-domain technique are used to investigate the physical mechanism of reflective PH formation. The field intensity distributions and photonic fluxes near the concave mirror are analyzed for working in the reflection mode. The asymmetric vortexes of Poynting vectors cause the reflective PH with a large bending angle. By changing the refractive index of the dielectric film, the shape and curvature of the reflective PH can be efficiently adjusted. Moreover, the narrow waist of the reflective PH is obtained beyond half of the incident wavelength. This compact dielectric-coated concave mirror has proven its practicability for integrated photonic circuits in the reflection mode.
Implication of oxidative lesions and base excision repair in the tissue selectivity of the somatic instability of CAG repeats in Huntington’s diseease

Huntington’s disease (HD) is a neurodegenerative fatal disease caused by the expansion of CAG repeats in the Huntingtin gene. The expansion length is unstable and proportional to the disease severity. The instability affects differently several tissues, among which the striatum that shows a high instability and degenerates, whereas the cerebellum that shows limited instability is spared from the disease. We addressed the role of oxidative lesions and Base Excision Repair (BER) in the tissue-selectivity of the instability in striatum and cerebellum of R6/1 mouse model. Interestingly, we observed a similar level of oxidative lesions at both tissues. Levels and activities of main BER proteins were globally decreased in striatum relative to cerebellum. Moreover we found that repair outcome is dependent upon BER stoichiometries, lesion location and sequence. Our results suggest a poor cooperation between BER activities that could underlie tissue-specificity of somatic instability in HD.
Inferring weighted gene annotations from expression data

Annotating genes with information describing their role in the cell is a fundamental goal in biology, and essential for interpreting data-rich assays such as microarray analysis and RNA-Seq. Gene annotation takes many forms, from Gene Ontology (GO) terms, to tissues or cell types of significant expression, to putative regulatory factors and DNA sequences. Almost invariably in gene databases, annotations are connected to genes by a Boolean relationship, e.g., a GO term either is or isn’t associated with a particular gene. While useful for many purposes, Boolean-type annotations fail to capture the varying degrees by which some annotations describe their associated genes and give no indication of the relevance of annotations to cellular logistical activities such as gene expression. We hypothesized that weighted annotations could prove useful for understanding gene function and for interpreting gene expression data, and developed a method to generate these from Boolean annotations and a large compendium of gene expression data. The method uses an independent component analysis-based approach to find gene modules in the compendium, and then assigns gene-specific weights to annotations proportional to the degree to which they are shared among members of the module, with the reasoning that the more an annotation is shared by genes in a module, the more likely it is to be relevant to their function and, therefore, the higher it should be weighted. In this paper, we show that analysis of expression data with module-weighted annotations appears to be more resistant to the confounding effect of gene-gene correlations than non-weighted annotation enrichment analysis, and show several examples in which module-weighted annotations provide biological insights not revealed by Boolean annotations. We also show that application of the method to a simple form of genetic regulatory annotation, namely, the presence or absence of putative regulatory words (oligonucleotides) in gene promoters, leads to module-weighted words that closely match known regulatory sequences, and that these can be used to quickly determine key regulatory sequences in differential expression data.
Effects of Stored Pollens from Wild Actinidia eriantha Vines on Some Fruit Quality Traits

Our study was conducted to determine In vitro germination ability of pollens from 25 wild Actinidia eriantha genotypes after one year freeze storage, afterwards we examined fertilization ability of stored pollens of 8 genotypes selected according to In vitro test results from aforementioned 25 genotypes, and finally investigated effects of stored viable pollens from “MH67”, “MH55”, “MH48” and “MH45” genotypes on fruit quality characters of the female experimental plant “M3” as the main purpose. Non-pollinated “M3” kiwifruit plant was taken as control. We found that In vitro germination and fertilization ability of different stored pollen sources, and also fruit quality characters including dry matter, total sugar, titratable acid, vitamin C, total polyphenol, total flavonoid, chlorophyll (“a”, “b”, and total) and carotenoid contents except total soluble solid content were significantly different. MH67 and MH45 genotypes were evaluated as the most suitable pollenizers which can be recommended as new candidate cultivars because of long term storage ability and brought about desired fruit quality characters. They also will be investigated more at further breeding studies.
Fermented Product from Bacillus subtilis Inhibits Lipid Accumulation and Ammonia Production of Broiler Chicks

This study investigated the advantages of feeding the fermented product from Bacillus subtilis on improving feed efficiency and reducing fat accumulation and ammonia production in broiler chicks. Eighty, seven-day old female broilers were divided into four groups with five pens of four chicks each. One group was fed the diet without supplementation of fermented product from Bacillus subtilis and other three groups were fed the diet with 0.5, 1.0 or 2.0% for 21 days from 7 to 28 day of age. It was assumed that fermented product from Bacillus subtilis would improve growth characteristics with lower fat accumulation and ammonia production. Body weight gain, abdominal fat weight and liver weight were not significantly affected, whereas feed intake and feed efficiency was significantly improved in chicks fed fermented product from Bacillus subtilis as compared with the control (P<0.05). In comparison with the control, activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase, and contents of triglyceride and cholesterol in the liver and carcass were significantly decreased in treatment groups (P<0.05). Ammonia production was reduced by feeding this feed additive, but not N-total, N-urate and N-ammonia contents of excreta, pH and N-ammonia content of caecum. In conclusion, feeding fermented product from Bacillus subtilis at 1.0% gave better feed efficiency with lower carcass and hepatic lipid accumulation and ammonia production.

The Language of Right-Wing Populist Leaders: Not So Simple

Political scientists have long asserted that populists use simpler language than their mainstream rivals to appeal to ordinary people and distance themselves from elites. However, there is little comparative evidence in support of that claim. In this study, we investigate the linguistic simplicity of four right-wing populists compared to their principal opponents in the United States, France, United Kingdom, and Italy. We do so by analysing a corpus of approximately one million words from leaders’ speeches, using a series of linguistics measures for evaluating simplicity. Contrary to expectations, we find that Donald Trump was only slightly simpler than Hillary Clinton, while Nigel Farage in the UK and Marine Le Pen in France were more complex than their main rivals, and Italy’s Matteo Salvini was simpler on some measures but not others. We conclude that the simple language claim is not borne out and that other aspects of the received wisdom about populism should be re-examined.
Development and characterization of self-nanoemulsifying drug delivery system (SNEDDS) formulation for enhancing dissolution of fenofibric acid

Fenofibric acid is an active form of fenofibrate and a poorly water-soluble drug. The study aims to formulate and characterize self-nanoemulsifying drug delivery system (SNEDDS) to improve the dissolution of fenofibric acid. The selection of oil, surfactant, and cosurfactant for preliminary screening was determined by the solubility study of fenofibric acid in various vehicles. The composition of selected oil, surfactant, and cosurfactant was glyceryl monolinoleate (Maisine® CC), Kolliphor® RH 40, and Transcutol® HP, PEG 400 respectively. The study results showed that the best SNEDDS formulation was Fd with a ratio of oil, surfactant, and cosurfactant of 10:70:20 % v/v/v (Maisine® CC: Kolliphor® RH 40: Transcutol® HP). It produced good self-nanoemulsifying drug delivery system such as the droplet size was 15.30 nm, 99.27 % transmittance, thermodynamically stable, self-emulsification time was 18.84 seconds, the morphology of the formed nanoemulsion droplets was observed as sphere-shaped droplets and 1.6 fold increase in the dissolution of fenofibric acid.
Correlation of native point defects and photocatalytic activity of annealed ZnO nanoparticle studied by electron spin resonance and photoluminescence emission

In this paper, we investigate the origin of point defects revealed by electron spin resonance (ESR) and photoluminescence (PL) emission in correlation with the photocatalytic activity of ZnO nanocrystals subjected to thermal annealing at various temperatures. Two ESR signals at g ∼ 1.96 and ∼2.003 were consistently observed in all annealed ZnO samples. However, their relative intensities have changed, indicating that the point defect densities were influenced by the annealing temperature. Interestingly, when doping nanoZnO with Cr3+, the Q-band ESR measurements at T = 100 K did show that the g ∼ 1.96 signal was completely passivated, suggesting that the origin of the signal lies in the electrons located near the conduction band, i.e. at a shallow-donor level. The intensity of the g ∼ 2.003 signal decreased by rising the annealing temperature, and this is attributed to the depopulation of zinc interstitials through the thermally induced migration process and/or recombination with the zinc vacancies. The green PL emission line at ∼520 nm, which is dominant in the 700 °C annealed ZnO sample, shows a correlation with the ESR signal at g ∼ 1.96, whose origin is attributed to the radiative transition of the electron from the shallow donor level to the singly ionized zinc vacancy. Furthermore, the high density of the shallow donor electron states was found to be primarily responsible for the high photocatalytic activity in the degradation of methylene blue.
Prognostic value of pre-treatment routine hematological parameters in breast carcinoma: Advantageous or deleterious?

Introduction: The most common malignancy which endangers the quality of life in females is breast cancer. It is also the major public problem in society and despite advances in treatment strategies, it still leads to high mortality. In all breast cancer patients, the first assessment done before surgery is the complete blood count (CBC). There exists a strong relationship between immune response of the body and clinical staging of breast cancer. This study aimed to determine the most reliable hematological markers for the prognosis of breast cancer, and to evaluate the correlation between hematological parameters and disease staging. Methods: This study was a case control study conducted for a period of 3 years from Jan 2016 to December 2018 in the Department of Pathology (R.L. hospital and Research Center attached to Sri Devaraj Urs medical college, Tamaka, Kolar, Karnataka). The comparison of the hematological parameters was done between the study group (70 cases) and the control group (20 cases). The relation between the hematological parameters and the various stages of breast cancer was analyzed before initiating the treatment. Results: The majority of the breast cancer patients were of stage 2. The hemoglobin concentration, red blood cell (RBC) count, lymphocyte count, and were reduced in the study group, with a significant difference (p < 0.05) when compared to the controls. Hemoglobin concentration, RBC count, hematocrit, white blood cell (WBC) count, and absolute lymphocyte count were inversely proportional to the stage of breast cancer. The absolute count, ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were directly proportional to the progression of disease. Conclusion: Hemoglobin, RBC count, WBC count (including differential count), NLR, and PLR are the key hematological indicators which predict the severity and mortality risk of breast carcinoma.

Cemented on the Rock. A Pleistocene Outer Shelf Lithobiont Community from Sicily, Italy

The lithobiont community encrusting an early Pleistocene palaeocliff cropping out north of Augusta (SE Sicily, Italy) was investigated based on field observations and laboratory inspection of two rocky samples. Bryozoans, serpulids, brachiopods and bivalves encrusted part of the exposed surfaces that were bored mostly by clionaid sponges. Bryozoans, with at least 25 species detected on the rocky samples, are the most diversified skeletonized lithobionts also accounting for the highest number of colonies/specimens and highest coverage. Brachiopods, with the only species Novocrania anomala and a few but large cemented valves, cover wide surfaces. Serpulids, with two species identified on the sampled rocks and further two on the outcrop, were intermediate. A multiphase colonization is present, including a final epilithobiont community locally formed on eroded surfaces exposing a network of pervasive borings. The co-occurrence of very sciaphilic species having circalittoral to bathyal distributions suggests that the studied community thrived on a rocky substratum located near or at the shelf break, probably belonging to the shelf break (or RL) biocoenosis, also in agreement with observations on the fossil content of neighboring marly sediments. The observed relationships among colonizers largely represent mere superimpositions, and real interactions are not enough to state species competitiveness.
Androgen biosynthetic capabilities of isolated seminiferous tubules, interstitial and whole testis tissues of normal and cryptorchid rats /

3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete.
The relevance of ecoregions and mountainous environments in the diversity and endemism of land gastropods

Twenty-five sub-ecoregions make Argentina from southern South America a favored area to study the mutual correspondence between environments and biodiversity. Unfortunately, efforts devoted to study these environments are unbalanced, with the subtropical dry forests less studied than the tropical and subtropical humid ones. Since the limits of ecoregions are based on vegetation criteria, land gastropods represent an independent source of information to test the relevance of sub-ecoregions in different aspects of biodiversity. We ask if land gastropods mirror these traditional diversity patterns when their distributions are framed in the context of sub-ecoregions. Additionally, we want to test if short-range endemic species (SRE) are randomly scattered across the sub-ecoregions. We first built an updated taxonomic checklist and mapped all the valid records compiled to date. Taxonomic richness, taxonomic diversity, and beta-diversity between sub-ecoregions were calculated. We obtained a hierarchical grouping of sub-ecoregions and the respective list of species that significantly support each cluster. We also developed two new analytical resources: a radial plot for showing the species composition of clusters resolved at three taxonomic levels, and a mixed coefficient of distributional size useful to identify SRE from sparse point records. This dimensionless measure of spatial range combines information of both the convex hull area and the length of the minimum spanning tree connecting point localities of presence. The Southern Andean Yungas and Dry Chaco are the species-level richest ecoregions. Although the Paranaense Forest harbors half of the number of species found in the Chaco Serrano, it reaches the highest score of taxonomic diversity because of the eclectic nature of their genera. SRE species are not randomly distributed across the sub-ecoregions, but they broadly overlap with the orographic Peripampasic arc extended over Chaco Serrano and Yungas Forests. SREs are highly dependent on the physical nature of the landscape.
