Significance of nuclear morphometry in cytological aspirates of breast masses
Kalhan Shivani,Dubey Suparna,Sharma Sonia,Dudani Sharmila
Journal of Cytology , 2010,
Abstract: Background : Breast carcinoma is the most common malignancy globally. Cytological evaluation in breast lesions is largely subjective. Gradual progression of cells from normal to invasive involves nuclear changes that need to be viewed objectively. Aims : This study aims to apply nuclear morphometry on cytological breast aspirates. It evaluates its utility in differentiating benign vs. malignant lesions and correlates it with cytologic grading in malignant cases. Setting and Design : Nuclear morphometric parameters of malignant and benign cases were compared. Parameters of malignant cases were correlated with cytologic grading. Materials and Methods : Cytology was used to categorize aspirates from breast lumps into malignant (53 cases) and benign (29 cases). One hundred cells per case in both groups were mapped on DEBEL Cytoscan and six geometrical and three textural parameters obtained were compared. In malignant cases, morphometry was correlated with Robinson′s cytologic grading, which was further correlated in tissue sections (45 cases) with modified Scarff-Bloom-Richardson histologic grading. Statistical Analysis : Students "t"-test was applied for comparison between benign and malignant cases. One-way ANOVA followed by Bonferroni′s post hoc comparison was applied to compare the three cytologic grades. Results were considered significant when P<0.05. Results : Nuclear morphometry successfully differentiated between benign and malignant aspirates and correlated significantly with cytologic grades. Morphometry was especially useful in the diagnosis of atypical ductal hyperplasia and ductal carcinoma in situ. Useful parameters were mean nuclear area, long axis, short axis and total run length. Cytohistologic correlation was 83.3%, 88.9% and 88.9% for cytological grades 1, 2 and 3 respectively. Conclusions : Nuclear morphometry was thus a useful objective tool in the evaluation of breast masses.
Interest-Rate Setting at the ECB Following the Financial and Sovereign Debt Crises, in Real-Time  [PDF]
Florence Bouvet, Sharmila King
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.25083
Abstract: We analyse European Central Bank (ECB) policy by estimating a forward-looking, augmented Taylor rule using expectations data. Specifically, we investigate the impact of the financial and sovereign debt crises on ECB policy. We find the European Overnight Index Average (EONIA) rises when expected economic activity is strong. Regardless of the inflation measure, inflation is not associated with the EONIA. Using a recursive estimation and a Chow test, we identify a policy shift in December 2008. The more generally accepted starting date of the crisis, August 2007, does not correspond to a statistically significant shift in the ECB policy. Using December 2008 for a policy shift, general financial market sentiment, as measured by VSTOXX, is not significant in explaining EONIA movements. The ECB’s response to a shock to economic activity has been more moderate since the crises. However, the EONIA increases as Greek sovereign risk rises, possibly from increasing demand for liquidity by banks.
Leakage Analysis of a Low Power 10 Transistor SRAM Cell in 90 nm Technology  [PDF]
Parimaladevi Muthusamy, Sharmila Dhandapani
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76087
Abstract: In this paper, a novel 10 Transistor Static Random Access Memory (SRAM) cell is proposed. Read and Write bit lines are decoupled in the proposed cell. Feedback loop-cutting with single bit line write scheme is employed in the 10 Transistor SRAM cell to reduce active power consumption during the write operation. Read access time and write access time are measured for proposed cell architecture based on Eldo SPICE simulation using TSMC based 90 nm Complementary Metal Oxide Semiconductor (CMOS) technology at various process corners. Leakage current measurements made on hold mode of operation show that proposed cell architecture is having 12.31 nano amperes as compared to 40.63 nano amperes of the standard 6 Transistor cell. 10 Transistor cell also has better performance in terms of leakage power as compared to 6 Transistor cell.
DDoS Attack Detection Using Heuristics Clustering Algorithm and Na?ve Bayes Classification  [PDF]
Sharmila Bista, Roshan Chitrakar
Journal of Information Security (JIS) , 2018, DOI: 10.4236/jis.2018.91004
Abstract:
In recent times among the multitude of attacks present in network system, DDoS attacks have emerged to be the attacks with the most devastating effects. The main objective of this paper is to propose a system that effectively detects DDoS attacks appearing in any networked system using the clustering technique of data mining followed by classification. This method uses a Heuristics Clustering Algorithm (HCA) to cluster the available data and Na?ve Bayes (NB) classification to classify the data and detect the attacks created in the system based on some network attributes of the data packet. The clustering algorithm is based in unsupervised learning technique and is sometimes unable to detect some of the attack instances and few normal instances, therefore classification techniques are also used along with clustering to overcome this classification problem and to enhance the accuracy. Na?ve Bayes classifiers are based on very strong independence assumptions with fairly simple construction to derive the conditional probability for each relationship. A series of experiment is performed using “The CAIDA UCSD DDoS Attack 2007 Dataset” and “DARPA 2000 Dataset” and the efficiency of the proposed system has been tested based on the following performance parameters: Accuracy, Detection Rate and False Positive Rate and the result obtained from the proposed system has been found that it has enhanced accuracy and detection rate with low false positive rate.
Outcome measures of bipolar hip arthroplasty for atraumatic hip disorders - A preliminary report
Dudani Baldev,Thawrani Dinesh,Chikale Shivanand
Indian Journal of Orthopaedics , 2005,
Abstract: Background: Bipolar hip arthroplasty was devised for fracture neck femur in elderly patients. Subsequently, indications have been expanded to include conditions affecting acetabulum like rheumatoid arthritis, osteoarthritis and avascular necrosis of femoral head. Materials and methods: We have studied the results of bipolar hip arthroplasty in 38 such patients, with severely involved acetabulum due to rheumatoid arthritis, avascular necrosis of femoral head and primary osteoarthritis. Acetabulum was reamed to get a tight ′equatorial′ or ′rim′ fit of the prosthesis. Prosthesis selected was 1 mm bigger than the maximum size of reamer used. Cement was used in femur whenever there was marked osteoporosis or wide medullary canal. Post operatively all patients were regularly screened for pain, range of movement, protrusio acetabuli, loosening / sinking of prosthesis and radiographic assessment of movement in the two bearings of prosthesis. Results: Overall results achieved were good to excellent in 80% of patients. Conclusions: The ultimate outcome is comparable to total hip arthroplasty. The added advantage is of low cost, simplicity of procedure and easy future revision.

Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: Mathematics is considered as an exceptionally difficult subject by majority of the students. The passpercentage of high school examination in this subject is very low in comparison to other subjects of the schoolcurriculum. Normally in a classroom it is difficult for a teacher to reach to all the students due to heterogeneousgroup of students and student teacher ratio. Hence there is a need of using innovative teaching methodologyalongwith in classroom teaching. Therefore, this paper is an attempt to highlight the role of CAI (Computer AssistedInstruction) in teaching of mathematics.

G. Sharmila
Bonfring International Journal of Research in Communication Engineering , 2011, DOI: 10.9756/bijrce.1002
Abstract: Communication plays very important role in day-to-day life of people. Due to fast growing age, multi carrier communication is preferred over single carrier waves for better transmission. One of the advantages of OFDM system over the single carrier system is the better performance in multipath environment. For narrowband operation, one may construct simple ampli ers whose noise gure and power gain are close to the theoretical optima allowed within an explicit power constraint.This paper introduces the design of a 1.5 GHz Low-Noise amplifier using Agilent ADS software. The proposed design aims to provide a better gain of 12.7 dB with low Noise Figure (NF) of 1.76 dB.

Experimental Investigation of Surface Plasmon Resonance Using Tapered Cylindrical Light Guides with Metal-Dielectric Interface  [PDF]
Sharmila Ghosh, Kaushik Brahmachari, Mina Ray
Journal of Sensor Technology (JST) , 2012, DOI: 10.4236/jst.2012.21007
Abstract: In this paper we report an experimental investigation on the observation of surface plasmon resonance at the metal- dielectric interface of silver coated tapered light guiding glass rods of different dimensions. Chemical deposition technique has been used for metallic deposition of silver on the Tapered glass rod. Angular interrogation in Kretschmann- like configuration of this non-planar (cylindrical) structure is used to locate the resonance dip in the reflectance mea- surement. Fabrication simplicity, in addition to the inherent advantage of using different types of tapered structures, makes this study important in the development of nanoplasmonics. The experimental study is accompanied by some interesting results.
