An Ensemble Classification and Hybrid Feature Selection Approach for Fake News Stance Detection

The developments in Internet and notions of social media have revolutionised representations and disseminations of news. News spreads quickly while costing less in social media. Amidst these quick distributions, dangerous or seductive information like user generated false news also spread equally. on social media. Distinguishing true incidents from false news strips create key challenges. Prior to sending the feature vectors to the classifier, it was suggested in this study effort to use dimensionality reduction approaches to do so. These methods would not significantly affect the result, though. Furthermore, utilising dimensionality reduction techniques significantly reduces the time needed to complete a forecast. This paper presents a hybrid feature selection method to overcome the above mentioned issues. The classifications of fake news are based on ensembles which identify connections between stories and headlines of news items. Initially, data is pre-processed to transform unstructured data into structures for ease of processing. In the second step, unidentified qualities of false news from diverse connections amongst news articles are extracted utilising PCA (Principal Component Analysis). For the feature reduction procedure, the third step uses FPSO (Fuzzy Particle Swarm Optimization) to select features. To efficiently understand how news items are represented and spot bogus news, this study creates ELMs (Ensemble Learning Models). This study obtained a dataset from Kaggle to create the reasoning. In this study, four assessment metrics have been used to evaluate performances of classifying models

A Clinical study on hypertensive emergencies

BACKGROUND AND OBJECTIVES : The clinical profile of patients with hypertensive emergencies presenting to hospitals in a developing country like ours is poorly known. The objective of the present study was to evaluate the modes of presentations, clinical profile and spectrum of target organ damage in patients with hypertensive emergencies. METHOD : This descriptive study was done at Coimbatore Medical College over the period of one and half years. The study population included patients admitted in this hospital with severely elevated blood pressure with clinical or laboratory evidence of acute target organ damage. The clinical and laboratory profile of 50 of these patients were evaluated. RESULTS : Males had higher chances of developing a hypertensive emergency compared to females. The commonest presenting symptoms were chestpain and dyspnoea, neurological deficit. Majority of the patients were known hypertensives. Higher levels of blood pressure at presentation were associated with an adverse outcome. Acute LVF was the commonest target organ damage observed. An in hospital mortality of 12% was observed in the present study. INTERPRETATION AND CONCLUSION : Known hypertensive are at a higher risk of presenting with acute target organ damage associated with a chestpain. Acute LVF is the commonest form of target organ damage encountered in the present study

Design and performance of subirrigation system in maize (Zea mays) in Kumulur farm, Trichy district, Tamil Nadu, India

Subirrigation system can furnish water to plants. The upward flux and the discharge rate must satisfy the plant’s lifesaving irrigation needs during summer. The experiment was laid out in  A-block of Eastern farm, Agricultural Engineering College and Research Institute, Kumulur, Trichy, Tamil Nadu. Subirrigation system spacing was arrived using Moody's equation calculated as 10 m. The experiment was laid out in spilt plot design with three replications. Four drain spacing levels (7.5, 10, 12.5 and 15 m) were the main plot treatments and two levels of depth and diameter of drain pipes (75 cm, 60 cm & 75 mm, 63 mm) were the sub plot treatments. The highest volumetric water content was recorded in 7.5 m spacing + 45 cm soil depth + lower reach (S1T3T1). Capillary rise on water table management system under subirrigation mode was fixed as 33.5 cm and the average deep percolation loss was obtained in 0.3 cm/d at development stage of crop period. The highest maize yield (4.30 t/ha) was obtained in 7.5 m spacing + 60 cm drain depth + 75 mm diameter (S1D3). The highest water use efficiency of (0.86 kg/m3) was recorded in 7.5 m spacing + 60 cm drain depth + 75 mm drain diameter (S1D3). This subirrigation system could furnish water to plants due to upward flux and the same system also functioned efficiently under drainage modes and removed the waterlogging during wet periods.       

Performance of water table management system for alleviating sodic soil reclamation at Kumulur farm, Trichy District, Tamil Nadu

Waterlogging and sodicity is common problem in many irrigation canal command areas. The water table management system is the next level of improving water management in irrigated agriculture. In the present study, the water table management system was designed to work effectively in the monsoon season as a controlled drainage system and sub-irrigation system during summer. The field evaluation of drain water quality analysis was carried out from the water table management system installed at A-block of Eastern Farm, Agricultural Engineering College and Research Institute, Kumulur farm, Trichy, Tamil Nadu during 2015-2016. The experiment was laid out in a split plot design with three replications. Four levels of drain spacing of drain pipes (7.5, 10, 12.5 and 15m) were the main plot treatment and two levels of depth and diameter of drain pipes (75 cm, 60 cm & 75 mm, 63 mm) were the sub plot treatments. The results showed that the recommended quality of press mud 2 t ha-1 was a help to reduce the Exchangeable sodium percentage (ESP) level of 33 to 28 percent when compared to other ameliorants. It was concluded that solubilization should be removed by providing drainage and brought to ESP level of less than 16 percent and 15 m drain spacing to adapt to reduce the ESP level below the critical.

High-pressure behavior of superconducting boron-doped diamond

This work investigates the high-pressure structure of freestanding superconducting ($T_{c}$ = 4.3\,K) boron doped diamond (BDD) and how it affects the electronic and vibrational properties using Raman spectroscopy and x-ray diffraction in the 0-30\,GPa range. High-pressure Raman scattering experiments revealed an abrupt change in the linear pressure coefficients and the grain boundary components undergo an irreversible phase change at 14\,GPa. We show that the blue shift in the pressure-dependent vibrational modes correlates with the negative pressure coefficient of $T_{c}$ in BDD. The analysis of x-ray diffraction data determines the equation of state of the BDD film, revealing a high bulk modulus of $B_{0}$=510$\pm$28\,GPa. The comparative analysis of high-pressure data clarified that the sp$^{2}$ carbons in the grain boundaries transform into hexagonal diamond.Comment: 7 pages, 4 figure
