Heredity for generalized power domination

In this paper, we study the behaviour of the generalized power domination number of a graph by small changes on the graph, namely edge and vertex deletion and edge contraction. We prove optimal bounds for $\gamma\_{p,k}(G-e)$, $\gamma\_{p,k}(G/e)$ and for $\gamma\_{p,k}(G-v)$ in terms of $\gamma\_{p,k}(G)$, and give examples for which these bounds are tight. We characterize all graphs for which $\gamma\_{p,k}(G-e) = \gamma\_{p,k}(G)+1$ for any edge $e$. We also consider the behaviour of the propagation radius of graphs by similar modifications.Comment: Discrete Mathematics and Theoretical Computer Science, 201

Suppression of beating noise of narrow-linewidth erbium-doped fiber ring lasers by use of a semiconductor optical amplifier

Beating noise in narrow-linewidth erbium-doped fiber ring lasers puts severe limitations on applications of the lasers. We demonstrate the suppression of beating noise in fiber ring lasers by using a semiconductor optical amplifier in the laser cavity, which acts as a high-pass filter. Two different ring structures are presented as examples to demonstrate this beating noise suppression

Hatching of Olive ridley turtle twin hatchlings

A clutch of 126 olive ridley (Lepidochelys olivacea) turtle eggs was laid at Palapetty Beach, Thrissur District, Kerala on 15th January 2016 and relocated by members of the Kanyakumari Turtle NEWS Club to the hatchery at Palapetty. On 02nd March 2016, after 46 days of incubation, 58 hatchlings emerged from the nest unaided in the early morning. The nest was excavated three hours after emergence of the first hatchling, at which time 14 more hatchlings emerged from the exposed eggs including two pairs of twins (Table 1; for example see Figure 1) which emerged from the eggshells on their own. The hatchlings were transported to a holding tank 15min post-hatching. The twin hatchlings were unable to remain afloat and their movement on land was also impaired as they remained connected by the respective yolk sacs. The first pair of twin hatchlings died half an hour after hatching, while the second pair of twins survived for six hours. Four other hatchlings which emerged from the exposed eggs died before being introduced to the holding tank. The surviving hatchlings were released to sea approximately nine to thirteen hours after hatching

Study on Intuitionistic Fuzzy Abundant Semigroup

We present some features of intuitionistic fuzzy subsets on an abundant semi- group in this study. Also presented the concept of intuitionistic fuzzy abundant semigroups, as well as some of its features.We also define homomorphism and investigate the image and inverse image of an intuitionistic fuzzy abundant semigroup when homomorphism is applied

Evaluation of the zucker diabetic fatty (ZDF) rat as a model for human disease based on urinary peptidomic profiles

Representative animal models for diabetes-associated vascular complications are extremely relevant in assessing potential therapeutic drugs. While several rodent models for type 2 diabetes (T2D) are available, their relevance in recapitulating renal and cardiovascular features of diabetes in man is not entirely clear. Here we evaluate at the molecular level the similarity between Zucker diabetic fatty (ZDF) rats, as a model of T2D-associated vascular complications, and human disease by urinary proteome analysis. Urine analysis of ZDF rats at early and late stages of disease compared to age- matched LEAN rats identified 180 peptides as potentially associated with diabetes complications. Overlaps with human chronic kidney disease (CKD) and cardiovascular disease (CVD) biomarkers were observed, corresponding to proteins marking kidney damage (eg albumin, alpha-1 antitrypsin) or related to disease development (collagen). Concordance in regulation of these peptides in rats versus humans was more pronounced in the CVD compared to the CKD panels. In addition, disease-associated predicted protease activities in ZDF rats showed higher similarities to the predicted activities in human CVD. Based on urinary peptidomic analysis, the ZDF rat model displays similarity to human CVD but might not be the most appropriate model to display human CKD on a molecular level

A Novel Hybrid Classification Model For the Loan Repayment Capability Prediction System

Classification is a powerful tool in Data mining to predict the loan repayment capability of a banking customer. This paper evaluates the performance of various classification algorithms and selects the most appropriate one for predicting the class label of the credit data set as good or bad. Feature selection is a data pre-processing technique refers to the process of identifying the most beneficial features for a given task, while avoiding the noisy, irrelevant and redundant features of the dataset. These irrelevant noisy features results in a poor accuracy for the selected classifier. In order to improve the accuracy of a classifier, the feature selection plays a vital role as a data preprocessing step. Feature selection technique reduces the dimensionality of the feature set of the dataset. This paper has two objectives. First objective is to find out the best classifier algorithm for the credit data set using two different tools such as weka and R. Here the experiment proved that Random Forest performs better for loan repayment credibility prediction system. The second objective is to evaluate the performance of various feature selection methods based on Random Forest classification method. Also a novel hybrid model is developed for the same

Check list of fishes of the Gulf of Mannar ecosystem, Tamil Nadu, India

Gulf of Mannar Ecosystem (GOME) covers an area spread over Rameswaram and Kanyakumari for about 19000 km2 and lies between 78°11’E and 79°15’ E longitude and 8°49’N and 9°15’N latitude. The 21 coral islands form a network of habitats for different kinds of fishes and marine organisms. Fish samples were collected during April 2005 to March 2010 from different centers viz., Vembar, Tharuvaikulam, Vellapatti, Therespuram, Tuticorin, Alangarathattu, Pazhaykayal, Punnakayal, Kayalpattinam, Veerapandiapattinam, Thiruchendur and Manappad of Gulf of Mannar ecosystem. The present check list was the first attempt to produce a systematic list of fishes found in the Gulf of Mannar ecosystem. It includes 476 genera and 1182 species in 144 families and 39 orders, of which 628 species have been recorded in the present study
