Some Edge Product Cordial Graphs in the Context of Duplication of Some Graph Elements  [PDF]
Udayan M. Prajapati, Prakruti D. Shah
Open Journal of Discrete Mathematics (OJDM) , 2016, DOI: 10.4236/ojdm.2016.64021
Abstract: For a graph\"\", a function\"\" is called an edge product cordial labeling of G, if the induced vertex labeling function is defined by the product of the labels of the incident edges as such that the number of edges with label 1 and the number of edges with label 0 differ by at most 1 and the number of vertices with label 1 and the number of vertices with label 0 differ by at most 1. In this paper, we show that the graphs obtained by duplication of a vertex, duplication of a vertex by an edge or duplication of an edge by a vertex in a crown graph are edge product cordial. Moreover, we show that the graph obtained by duplication of each of the vertices of degree three by an edge in a gear graph is edge product cordial. We also show that the graph obtained by duplication of each of the pendent vertices by a new vertex in a helm graph is edge product cordial.

A comparative bacteriological profile and antibiogram of dacryocystitis
CP Shah,D Santani
Nepalese Journal of Ophthalmology , 2011, DOI: 10.3126/nepjoph.v3i2.5265
Abstract: Introduction: Dacryocystitis is an infection and an inflammation of the lacrimal sac and is an important cause of ocular morbidity in India. Objective: To isolate and identify the bacterial patterns associated with dacryocystitis and to determine their antibacterial sensitivity pattern. Materials and methods: A total of 100 lacrimal swab materials were subjected to bacaterial analysis. Children less than 8 years were not included in the study. Results: The chances of chronic dacryocystitis were more than acute dacryocystitis and were commonly found in the age group of 41 - 50 years. Females were more vulnerable to the infection than males. From a 100 samples a total of 122 bacterial isolates were obtained. Both Gram positive and Gram negative bacteria were equally distributed in the study. The most common organism associated with the infection was S. aureus. The antibacterial sensitivity showed more effectiveness towards Gram positive isolates than Gram negative isolates. Conclusion: Both Gram positive and Gram negative organism are associated with with chronic dacryocystitis. Knowledge of the bacteriology of dacryocystitis and the susceptibility of the bacteria towards antibiotics will better guide a clinician in the choice of the medication for the most appropriate drug for the treatment.

Modelling interactions in high-dimensional data with Backtracking
Rajen D. Shah
Statistics , 2012,
Abstract: We study the problem of high-dimensional regression when there may be interacting variables. Approaches using sparsity-inducing penalty functions such as the Lasso (Tibshirani, 1996) can be useful for producing interpretable models. However, when the number variables runs into the thousands, and so even two-way interactions number in the millions, these methods become computationally infeasible. Typically variable screening based on model fits using only main effects must be performed first. One problem with screening is that important variables may be missed if they are only useful for prediction when certain interaction terms are also present in the model. To tackle this issue, we introduce a new method we call Backtracking. It can be incorporated into many existing high-dimensional methods based on penalty functions, and works by building increasing sets of candidate interactions iteratively. Models fitted on the main effects and interactions selected early on in this process, guide the selection of future interactions. By also making use of previous fits for computation, as well as performing calculations is parallel, the overall run-time of the algorithm can be greatly reduced. The effectiveness of our method when applied to regression and classification problems is demonstrated on simulated and real data sets. In the case of using Backtracking with the Lasso, we also give some theoretical support for our procedure.
Auto Disinfectant Cleaner using AVR microcontroller
M. Huned,A. Shah,D. H. Shah
International Journal of Electronics and Computer Science Engineering , 2012,
Abstract: The trend of microcontroller in industrial as well as domestic application is increasing now-a-days. The use of microcontroller is increasing due to the following advantages/features of controller such as Processor reset, Device clocking, central processor, RAM, I/O pins and Instruction cycle timers. There are two types ofmicrocontroller available. They are- Embedded (8,16,32-bit) and Digital Signal Processors. Now-a-days advanced controllers such as PIC, ARM and AVR are widely used in which AVR is used mostly due to several advantages. The disinfectant cleaner used by doctors to clean the medical instruments specially used in Endoscopy are very large in size, bulky and costly. The design of Disinfectant Cleaner is cost effective, light in weight, mobile and user friendly. Atmel AVR 8- and 32-bit microcontrollers deliver a unique combination of performance, power efficiency, and design flexibility. Optimized to speed time to market, they are based on the industry's most code-efficient architecture for C and assembly programming. No other microcontrollers deliver more computing performance with better power efficiency.
Transdermal Drug Delivery Technology Revisited : Recent Advances
S. H. Shah,D.Shah
Pharmaceutical Reviews , 2008,
Abstract: The number of medications and the ways in which they can be administered have expanded dramatically over the years. One such advance has been the development of transdermal patch delivery systems. Transdermal drug technology specialists are continuing to search for new methods that can effectively and painlessly deliver larger molecules in therapeutic quantities to overcome the difficulties associated with the oral route. Transdermal Drug Delivery System is the system in which the delivery of the active ingredients of the drug occurs by the means of skin. Skin is an effective medium from which absorption of the drug takes place and enters the circulatory system. Various types of transdermal patches are used to incorporate the active ingredients into the circulatory system via skin. The patches have been proved effective because of its large advantages over other controlled drug delivery systems. This review article covers a brief outline of various components of transdermal patch, applications of transdermal patch, their advantages, disadvantages, when the transdermal patch are used and when their use should be avoid and some of the recent development in the field along with the latest patents in this field.

Open Journal of Obstetrics and Gynecology (OJOG) , 2018, DOI: 10.4236/ojog.2018.88076
Abstract: This is a case of primigravida of 35 years of age having spontaneous conception & 14.5 wks. pregnancy with retention of urine and pain in lower abdomen for 5 days. There was history of unsuccessful attempt of correction of retroversion one day prior. Transabdominal USG (ultrasonography) confirmed 14.5 wks. live pregnancy with incarceration of uterus. In this case, only GA (general anaesthesia) corrected retroversion & incarceration.
Anesthetic Management of a case of severe Dilated Cardiomyopathy with Splenic Abscess for Splenectomy: Case Report
Surbhi D Mundada,Bharat Shah
Indian Anaesthetists' Forum , 2011,
Abstract: Dilated cardiomyopathy (DCM) is characterized by dilatation and impaired systolic function of one or both ventricles. Malignant arrhythmias are the most common cause of death in DCM. Around 50% of cases of non-ischemic dilated cardiomyopathy are idiopathic. Anaesthetic management of these patients is quite challenging. The anaesthesiologist must have the knowledge of its pathophysiology, clinical features, diagnostic evaluations and the treatment modalities. This is a report of successful anaesthetic management of a patient with severe DCM just recovered from cardiac failure with septic foci undergoing splenectomy under general anaesthesia
Min-wise hashing for large-scale regression and classification with sparse data
Rajen D. Shah,Nicolai Meinshausen
Statistics , 2013,
Abstract: Large-scale regression problems where both the number of variables, $p$, and the number of observations, $n$, may be large and in the order of millions or more, are becoming increasingly more common. Typically the data is sparse: only a fraction of a percent of the entries in the design matrix are non-zero. Nevertheless, often the only computationally feasible approach is to perform dimension reduction to obtain a new design matrix with far fewer columns, and then work with this compressed data. $b$-bit min-wise hashing (Li and Konig, 2011) is a promising dimension reduction scheme for sparse binary matrices. Despite encouraging empirical results, theory to explain its success has been lacking to a large extent. In this work we study the prediction error of procedures which perform regression in the new lower-dimensional space after applying the method. We also show how sparse continuous data can be handled by a variant of the method. For both linear and logistic models we show that the average prediction error vanishes asymptotically as long as $q \|\beta^*\|_2^2 /n \rightarrow 0$, where $q$ is the maximal number of non-zero entries in each row of the design matrix and $\beta^*$ is the coefficient of the linear predictor. We also show that ordinary least squares or ridge regression applied to the reduced data can allow us to capture interactions in the original data, without a modification of the original procedure.
