Artificial Neural Network based Cancer Cell Classification
This paper addresses the system which achieves auto-segmentation and cell characterization for prediction of percentage of carcinoma (cancerous) cells in the given image with high accuracy. The system has been designed and developed for analysis of medical pathological images based on hybridization of syntactic and statistical approaches, using Artificial Neural Network as a classifier tool (ANN) [2]. This system performs segmentation and classification as is done in human vision system [1] [9] [10] [12], which recognize objects; perceives depth; identifies different textures, curved surfaces, or a surface inclination by texture information and brightness. In this paper, an attempt has been made to present an approach for soft tissue characterization utilizing texture-primitive features and segmentation with Artificial Neural Network (ANN) classifier tool. The present approach directly combines second, third, and fourth steps into one algorithm. This is a semi-supervised approach in which supervision is involved only at the level of defining structure of Artificial Neural Network; afterwards, algorithm itself scans the whole image and performs the segmentation and classification in unsupervised mode. Finally, algorithm was applied to selected pathological images for segmentation and classification. Results were in agreement with those with manual segmentation and were clinically correlated [18] [21].

On a notion of maps between orbifolds, I. function spaces
This is the first of a series of papers which are devoted to a comprehensive
theory of maps between orbifolds. In this paper, we define the maps in the more
general context of orbispaces, and establish several basic results concerning
the topological structure of the space of such maps. In particular, we show
that the space of such maps of C^r-class between smooth orbifolds has a natural
Banach orbifold structure if the domain of the map is compact, generalizing the
corresponding result in the manifold case. Motivations and applications of the
theory come from string theory and the theory of pseudoholomorphic curves in
symplectic orbifolds.Comment: Final version, 46 pages. Accepted for publication in Communications
in Contemporary Mathematics. A preliminary version of this work is under a
different title "A homotopy theory of orbispaces", arXiv: math. AT/010202
Identification and Analysis of Novel Amino-Acid Sequence Repeats in Bacillus anthracis str. Ames Proteome Using Computational Tools
We have identified four repeats and ten domains that are novel
in proteins encoded by the Bacillus
anthracis str. Ames proteome using automated
in silico methods. A “repeat” corresponds to a region
comprising less than 55-amino-acid residues that occur
more than once in the protein sequence and sometimes present
in tandem. A “domain” corresponds to a conserved region with
greater than 55-amino-acid residues and may be present as
single or multiple copies in the protein sequence.
These correspond to (1) 57-amino-acid-residue PxV domain,
(2) 122-amino-acid-residue FxF domain, (3) 111-amino-acid-residue
YEFF domain, (4) 109-amino-acid-residue IMxxH domain,
(5) 103-amino-acid-residue VxxT domain, (6) 84-amino-acid-residue
ExW domain, (7) 104-amino-acid-residue NTGFIG domain,
(8) 36-amino-acid-residue NxGK repeat, (9) 95-amino-acid-residue
VYV domain, (10) 75-amino-acid-residue KEWE domain,
(11) 59-amino-acid-residue AFL domain, (12) 53-amino-acid-residue
RIDVK repeat, (13) (a) 41-amino-acid-residue AGQF repeat and
(b) 42-amino-acid-residue GSAL repeat. A repeat or domain type is
characterized by specific conserved sequence motifs. We discuss
the presence of these repeats and domains in proteins from other
genomes and their probable secondary structure
A comparative clinical study on the effect of Gudashunti Nasya and Kola Kulattadi Ruksha Sweda in Manyasthamba
Due to present day lifestyle, a greater number of people are inclined to desk work and computer usage leading to many disorders. Manyasthamba is one among such disorders where the stiffness of neck with severe pain is the classical symptom which hampers our day to day life. While explaining treatment of Manyasthamba our Acharyas explained Rukshasweda and Nasya Karma as main line of treatment. Here a study was done by taking Gudashunti Yoga explained in Sharangadara Samhita indicated for Nasya and Kolakulattadi Churna indicated in Vatavyadhi explained in Ashtanga Sangraha for Ruksha Churna Sweda. A comparative clinical study of 40 patients suffering from Manyastambha were selected after thorough investigation. Patients were subjected to Nasya Karma in Group A and Ruksha Sweda and Nasya Karma in Group B for 7 days. Patients were assessed based on standard parameters before and after treatment and 7 days follow up. The statistical analysis revealed that there was a significant improvement in parameters like pain and stiffness. Hence proving the efficacy in the condition
Low-stress mechanical properties and fabric hand of cotton and polylactic acid fibre blended knitted fabrics
Low-stress mechanical behavior of cotton-rich/polylacticacid blended fabrics has been investigated and the results arecompared with cotton and polylactic acid fibre fabrics. Thepolylactic acid fibres are mixed with cotton fibres in two differentproportions, namely 20% and 35% and spun into 14.76 tex (40sNe) yarn. The yarns are then knit into single jersey structurefollowed by chemical pretreatments and relaxation. The relaxedfabrics are tested for low-stress mechanical properties usingKawabata evaluation system for fabrics (KES-F) and the handvalues are calculated. The results show that the addition of PLAfibres to cotton enhances the smoothness and softness of theblended fabrics. The total hand value of the fabrics rangesbetween 3.2 and 3.5
High sensitivity C-reactive protein levels across spectrum and severity of coronary artery disease
Background: C-reactive protein (CRP) is an acute-phase reactant protein synthesized by the liver in response to acute\ud
stress in a wide range of acute and chronic inflammatory conditions. In healthy subjects and patients presenting with\ud
coronary artery disease (CAD), elevated levels of CRP has repeatedly been demonstrated to predict future cardiovascular\ud
events.\ud
Methods: We measured high sensitivity C-reactive protein (hs-CRP) levels in 382 consecutive patients with CAD and 60 healthy controls by immunoturbidimetry method. Risk factors like hypertension, diabetes mellitus, dyslipidaemia,smoking, obesity and family history of premature CAD were assessed.\ud
Results: The mean age of patients with CAD was 53.5±11.8 years (303 males) and that of control group was 50.83±8.07(28 males). The patient group had significant higher concentration of mean hs-CRP levels when compared\ud
with the healthy control group (1.8±1.9 mg/L vs 0.35±1.1 mg/L, p<0.001). The mean hs-CRP levels of unstable angina\ud
(USA) and myocardial infarction (MI) patients was higher than chronic stable angina (CSA) patients (p<0.05). Based\ud
on the disease severity, we found a significantly higher hs-CRP levels in patients of triple vessel disease when compared\ud
to patients with single vessel disease (p=0.01).\ud
Conclusions: Elevated serum hs-CRP levels provide a useful marker for cardiovascular risk which, when combined\ud
with traditional risk factors, may help improve global risk prediction. Our study showed a significant contribution of\ud
hs-CRP to coronary risk prediction with better discrimination
Risk Management and Mitigation for Building Construction Project in Sangli District
Risk analysis as the title suggests this is related to the construction management. Risk analysing technique is used for the purpose of risk management. Which type of risk is occurring and how it is analysed what are various mitigatory methods available. Risk management involves assessing the risk sources and designing strategies and procedures to mitigate those risks to an acceptable level. Measurement of risk factors plays an important role in the assessment of risk. This research proposes to develop risk assessment frameworks and mathematical model to identify the risk factors. Quantification and prioritization of risk factors will help to design controls, resource allocation policies and minimize the total cost. The proposed model can be applied to a complex system that is representative of actual business situations
