Detecting the Anti-Social Activity on Twitter using EGBDT with BCM

The rise of social media and its consequences is a hot topic on research platforms. Twitter has drawn the attention of the research community in recent years due to various qualities it possesses. They include Twitter's open nature, which, unlike other platforms, allows visitors to see posts posted by Twitter users without having to register. In twitter the sentiment analysis of tweets are used for detecting the anti-social activity event which is one of the challenging tasks in existing works. There are many classification algorithms are used to detect the anti-social activities but they obtains less accuracy. The EGBDT (Enhanced Gradient-Boosted Decision Tree) is used to optimize the best features from the NSD dataset and it is given as input to BCM (Bayesian Certainty Method) for detecting the anti-social activities. In this work, tweets from NSD dataset are used for analyzing the sentiment polarity i.e. positive or negative. The efficiency of the proposed work is compared with SVM, KNN and C4.5. From this analysis the proposed EGBDT and BCM obtained better results than other techniques

Automatic Detection of Road Cracks using EfficientNet with Residual U-Net-based Segmentation and YOLOv5-based Detection

The main factor affecting road performance is pavement damage. One of the difficulties in maintaining roads is pavement cracking. Credible and reliable inspection of heritage structural health relies heavily on crack detection on road surfaces. To achieve intelligent operation and maintenance, intelligent crack detection is essential to traffic safety. The detection of road pavement cracks using computer vision has gained popularity in recent years. Recent technological breakthroughs in general deep learning algorithms have resulted in improved results in the discipline of crack detection. In this paper, two techniques for object identification and segmentation are proposed. The EfficientNet with residual U-Net technique is suggested for segmentation, while the YOLO v5 algorithm is offered for crack detection. To correctly separate the pavement cracks, a crack segmentation network is used. Road crack identification and segmentation accuracy were enhanced by optimising the model's hyperparameters and increasing the feature extraction structure. The suggested algorithm's performance is compared to state-of-the-art algorithms. The suggested work achieves 99.35% accuracy

The Empirical Results of Conditional Analysis of Principals Reasons in Bullying Teachers

Starting from the bullying of teachers by principals, this paper elaborates (a) how incompetency of management favours its emergence, (b) how teachers can see it, and (c) whether this problem affects the performance of teachers or not. The empirical results show that motivation, a positive workplace, and not being bullied or agitated by principals increase teachers performance. The findings show that the teachers consider managements incompetency the major factor to be blamed. Collaboration between teachers can have a role in limiting this abuse. Because management is the key obligation for clearing the ethos and function of the company and clarifying the translation of words into the organization, there is some laggard of management in the way the control extracted from the structured authority is confused. Success strain!! In the light of the short- and long-term priorities and plans, colleges and organized entity made up of people operating, supervised and operationally, can operate every phase so the activities can be orchestrated and integrated in an equilibrated manner

Chemically-Derived Cuo/In2O3-Based Nanocomposite For Diode Applications

Nowadays, oxide-based semiconducting nanostructures are widely regarded as one of the most essential elements of the modern semiconductor industry and for a number of advanced technological functions in electronics and optoelectronic platforms. In this regard, a CuO-based nanocomposite was synthesized through a facile surfactant-free wet chemical strategy, and its potential for photoelectronic applications has been demonstrated. The nature of the composite phase and its other structural characteristics were studied in detail using Raman and X-ray photoelectron spectroscopic tools. The particulate characteristics of the composite were inferred using transmission electron microscopic measurements. Room temperature luminescence measurements revealed that the optical activity of the composite spreads across the red and near-infrared region of the electromagnetic spectrum through corresponding transitions. The optoelectronic capabilities of the processed composite were investigated through fabricating a CuO composite/ZnO nanowire-based p-n heterostructure and studying its associated current-voltage (I-V) characteristics under photon illumination. The nature of charge carriers, flat band potential, charge transfer resistance and carrier density were also studied individually and collectively for each component comprising the heterostructure through Mott-Schottky and Nyquist type impedance plots

Biodentine and Amniotic Membrane to Treat the Hidden Villain- A Rare Case of Labiocervical Vertical Groove

This case report signifies the importance of complications and early diagnosis of radicular groove and to discuss the treatment of combined endo-perio lesion using bone graft mixed with Platelet Rich Fibrin (PRF), amniotic membrane and biodentine. Labiocervical Vertical Groove (LCVG) presents various complications to the patients, especially if it extends to the pulpal space. Labiocervical vertical groove originating near the cervical area of tooth can extend to the radicular surface. These grooves can be mild, moderate or deep based on its extent and depth. This case report deals with the complications, degree of destruction and treatment of an intrabony defect associated with LCVG in maxillary central incisor in a 35-year-old male patient, who reported to the Department of Periodontics and Implantology with the chief complaint of mobility of teeth over a period of past two months. In this case report, authors have highlighted the advantages of saucerisation, PRF, amniotic membrane and biodentine to treat the bone loss along with restoration of the groove

Moreover, the blood–brain barrier (BBB) effectively blocks the transfer of cells, particles and large molecules, ie, drugs, across the brain. The most important challenge in the treatment of neurodegenerative diseases is the development of targeted drug delivery system. Theranostic strategies are known to combine therapeutic and diagnostic capabilities together. The aim of this review was to record the response to treatment and thereby improve drug safety. Nanotechnology offers a platform for designing and developing theranostic agents that can be used as an efficient nano-carrier system. This is achieved by the manipulation of some of the properties of nanoparticles (NPs), thereby enabling the attachment of suitable drugs onto their surface. The results provide revolutionary treatments by stimulation and thus interaction with targeted sites to promote physiological response with minimum side effects. This review is a brief discussion of the administration of drugs across the brain and the advantages of using NPs as an effective theranostic platform in the treatment of Alzheimer’s, Parkinson’s, epilepsy and Huntington’s disease. Keywords: theranostics, neurological disease, nanoparticles, imagin

Solid-State Photodimerization Reaction with Photosalient Effect and Photophysical and Electrochemical Properties of <i>N</i>‑Methylated 1‑Naphthylvinyl-4-Quinoline

Crystal packing-dependent photochemical reactions of several functional olefins have been explored, but not for 1-naphthylvinyl-4-quinoline (NVQ) and analogous N-methylated 1-naphthylvinyl-4-quinoline cation (MNVQ). Herein, crystal structure elucidation and photophysical and electrochemical properties for both NVQ and MNVQ, and photodimerization reaction with a photosalient effect for MNVQ have been investigated for the first time. The neutral compound NVQ stacks parallel in its crystal; however, having a distance of 4.43 Å between the CC bonds, it remained photoinert. Upon methylation at the quinoline-N, the resulting MNVQ cations stack parallel in a head-to-tail fashion with a distance of 3.6 Å between the CC bonds, and consequently it underwent [2 + 2] photocycloaddition reaction quantitatively to MQNCB dication, when irradiated under visible light (∼410 nm). Monitoring closely the single crystals of MNVQ under blue light showed that they burst upon exposure for 1 min, signifying a photosalient behavior. Measurements of photophysical properties showed that MNVQ exhibited a bathochromic shift in both absorption (by 4772 cm–1) and emission (by 6198 cm–1) compared to the neutral NVQ. Upon photodimerization, the MQNCB dication exhibited a hypsochromic and hypochromic shift both in absorption and emission compared to the MNVQ cation, a signature of cessation of conjugation. Cyclic voltammetry (CV) measurements showed that all three compounds are redox active and exhibit a reversible reduction event in the range of −0.6 to −0.9 V (vs Ag/AgCl). Experimental results have been substantiated by theoretical calculations
