A Comparative Analysis of Lexical/NLP Method with WEKA's Bayes Classifier

Various websites are available as source of microblogs. This is due to nature of microblogs on which people post real time messages about their attitudes on a various topics, talk about present issues, criticize, and articulate positive or negative sentiment for products they use in daily life. That?s why, manufacturing companies of such products have started to take these microblogs to get a sense of general sentiment for their product. Reply can be given by the companies on microblogs for the reactions of the users. Thus challenge is to build a technique to detect and summarize an overall sentiment. The proposed methodology examines sentiments on Twitter data contextually. Sentiment Analysis is the major aspect of present day NLP. Also, Twitter has emerged as the most important data source for present day NLP. In the work carried out, tweets are extracted from Twitter using Twitter API after authentication, a fine pre-processing is dealt and provided for further processing. Later, tag each word with their respective parts of speech using Part-Of-Speech (POS) tagger. SentiWordNet, WordNet and NLP weight assignment policies are used to assign weights and provide results. The analysis of same data set is also done with Na?ve Bayes classifier using WEKA - the data mining tool. Then results of both ? the proposed method and Na?ve Bayes are compared. (Then finally comparison between the results of proposed method with Na?ve Bayes classier is done.) The investigation proved that our method i.e. NLP technique works better than that of Na?ve Bayes Classifier. And this study also proves that the training set to the classier matters a lot in Machine Learning - ?Expected output can be accurate if and only if the training of a classifier is better?

Distributed Execution Indexing

This work-in-progress report presents both the design and partial evaluation of distributed execution indexing, a technique for microservice applications that precisely identifies dynamic instances of inter-service remote procedure calls (RPCs). Such an indexing scheme is critical for request-level fault injection techniques, which aim to automatically find failure-handling bugs in microservice applications.Distributed execution indexes enable granular specification of request-level faults, while also establishing a correspondence between inter-service RPCs across multiple executions, as is required to perform a systematic search of the fault space.In this paper, we formally define the general concept of a distributed execution index, which can be parameterized on different ways of identifying an RPC in a single service. We identify an instantiation that maintains precision in the presence of a variety of program structure complexities such as loops, function indirection, and concurrency with scheduling nondeterminism. We demonstrate that this particular instantiation addresses gaps in the state-of-the-art in request-level fault injection and show that they are all special cases of distributed execution indexing. We discuss the implementation challenges and provide an implementation of distributed execution indexing as an extension of \Filibuster{}, a resilience testing tool for microservice applications for the Java programming language, which supports fault injection for gRPC and HTTP

Enhancing the Performance of the T-Peel Test for Thin and Flexible Adhered Laminates

Symmetrically bonded thin and flexible T-peel specimens, when tested on vertical travel machines, can be subject to significant gravitational loading; with the associated asymmetry and mixed-mode failure during peeling. This can cause erroneously high experimental peel forces to be recorded which leads to uncertainty in estimating interfacial fracture toughness and failure mode. To overcome these issues, a mechanical test fixture has been designed for use with vertical test machines, that supports the unpeeled portion of the test specimen and suppresses parasitic loads due to gravity from affecting the peel test. The mechanism, driven by the test machine cross-head, moves at one-half of the velocity of the cross-head such that the unpeeled portion always lies in the plane of the instantaneous center of motion. Several specimens such as bonded polymeric films, laminates, and commercial tapes were tested with and without the fixture, and the importance of the proposed T-peel procedure has been demonstrated

Naturally Occurring Hydroxy Napthoquinones and Their Iron Complexes as Modulators of Radiation Induced Lipid Peroxidation in Synaptosomes

The modulation of radiation induced lipid peroxidation in synaptosomes by iron (II) and iron (III) complexes of two naturally occurring and therapeutically relevant naphthoquinones viz. 5,hydroxy-1,4 naphthoquinone; juglone and 2,hydroxy-1,4 naphthoquinone; lawsone, have been studied. At lower concentrations the complexes enhance lipid peroxidation predominantly through redox cycling as observed for Fe(II)- juglonate while at higher concentrations the complexes tend to limit lipid peroxidation through fast recombinations

Survival and success of zirconia compared with titanium implants: a systematic review and meta-analysis.

OBJECTIVE: This systematic review assessed the available evidence on the survival and success rate of zirconia and titanium implants. As secondary outcomes, aesthetic, radiographic and clinical parameters, as well as biological and mechanical complications, were considered. MATERIALS AND METHODS: A systematic search was performed up to March 2022 to identify CCTs/RCTs comparing zirconia and titanium implants with a minimum of 12 months of follow-up. Meta-analysis was performed when ≥ 2 articles with similar characteristics were retrieved. RESULTS: Four published articles with two RCTs (2 different patient populations) with 100 zirconia and 99 titanium implants that were followed up over 12-80 months were selected out of the 6040 articles. A non-statistically significant difference between zirconia and titanium implant survival at 12 months was suggested (P = 0.0938). The success rates were 57.5-93.3% and 57.1-100% for zirconia and titanium implants, respectively. The pink aesthetic score (PES) was higher for zirconia (10.33 ± 2.06 to 11.38 ± 0.92) compared to titanium implants (8.14 ± 3.58 to 11.56 ± 1.0). CONCLUSION: Based on the 2 RCTs retrieved in the literature, similar survival rates were reported for zirconia and titanium implants in the short term (12 months of follow-up). Future RCTs are warranted to evaluate the long-term outcomes of zirconia implants. CLINICAL RELEVANCE: Zirconia implants may be the procedure of choice, particularly in the aesthetic zone, since they show a similar survival and success rate as titanium implants on a short-term follow-up.

Bell-inequality in path-entangled single photon and purity test

Different degrees of freedom of single photons have been entangled and used as a resource for various quantum technology applications. We present a scheme to perform Bell's test and show the violation of CHSH inequality in a path-entangled single photon state using non-interferometric approach in beam splitter setting. We demonstrate this experimentally by generating and controlling path-entangled state using single photons from spontaneous parametric down-conversion and performing non-interferometric measurements using two detector module. The transition from violation of CHSH inequality to validity is demonstrated when the purity of single photons state decrease below 70\% visibility, $\mathcal{P} < 0.7$. Our procedure allows a purity test on any single photon source and to study quantum correlations on systems driven by dynamics where single particle entanglement with position space is prominent.Comment: 10 pages, 10 figures revised version with extended theoretical description and experimental resul

The Impact of Obesity on Physiologic Indicators

Obesity results in an alteration in the stress response that often results in adverse perinatal outcomes. This study investigated physiologic changes in 21 obese and 20 overweight women during pregnancy and the impact on vagal response (heart period and respiratory sinus arrhythmia), oxygenation, hemoglobin A1c (HbA1c) and systolic blood pressure at 20, 28 and 36 weeks of gestation. The impact of obesity on perinatal outcomes was investigated. Blood oxygen, systolic blood pressure, and HbA1c levels were significantly higher for the obese women as compared with overweight women. Monitoring physiologic mal-adaptation may permit early detection and intervention to improve perinatal outcomes
