Shoaib Amin Banday,Saba Mushtaq,A.H. Mir 보안공학연구지원센터(IJSIP) 2014 International Journal of Signal Processing, Image Vol.7 No.6

Biometrics has been one the main security solutions in almost every type of infrastructure (whether critical or non-critical) ranging from the main doors at home, libraries to the critical infrastructures like banks and airports. Despite the forceful impetus on research on biometric security that has taken biometrics from one simple level to much higher levels of security, there are still some open challenges in this field of security that need to be filled. Among all those challenges and loopholes, the security of template is of the most important concern. The reason for this is that we don’t want any identity compromises. If a biometric template in the database of the system of a person is compromised that consequently would mean identity theft of that person. This paper proposes a novel method that uses two different biometric data from the same person for making a biometric template against each person. The two biometric modalities that have been used in our work are left and right iris using best features. The features and verification of the proposed system has been done using MATLAB.

Bhattarai Dharmagat,Banday Aaqib Zaffar,Sadanand Rohit,Arora Kanika,Kaur Gurjit,Sharma Satish,Rawat Amit 한국현미경학회 2021 Applied microscopy Vol.51 No.1

Hair, having distinct stages of growth, is a dynamic component of the integumentary system. Nonetheless, derangement in its structure and growth pattern often provides vital clues for the diagnosis of systemic diseases. Assessment of the hair structure by various microscopy techniques is, hence, a valuable tool for the diagnosis of several systemic and cutaneous disorders. Systemic illnesses like Comel-Netherton syndrome, Griscelli syndrome, Chediak Higashi syndrome, and Menkes disease display pathognomonic findings on hair microscopy which, consequently, provide crucial evidence for disease diagnosis. With minimal training, light microscopy of the hair can easily be performed even by clinicians and other health care providers which can, thus, serve as a useful tool for disease diagnosis at the patient’s bedside. This is especially true for resource-constrained settings where access and availability of advanced investigations (like molecular diagnostics) is a major constraint. Despite its immense clinical utility and non-invasive nature, hair microscopy seems to be an underutilized diagnostic modality. Lack of awareness regarding the important findings on hair microscopy may be one of the crucial reasons for its underutilization. Herein, we, therefore, present a comprehensive overview of the available methods for hair microscopy and the pertinent findings that can be observed in various diseases.

A Comparative Study on Left and Right Endocardium Segmentation using Gradient Vector Field and Adaptive Diffusion Flow Algorithms

Yabrin Amin,Shoaib Amin Banday,A.H.Mir 보안공학연구지원센터 2016 International Journal of Bio-Science and Bio-Techn Vol.8 No.1

The cardiac Magnetic Resonance Imaging (MRI) provides high resolution images of the heart without radiation exposure. It is an excellent noninvasive test used by radiologist for proper detection of heart diseases. The manual segmentation of left ventricle in cine short axis MRI sequences takes an ample amount of time as compared to semi-automated segmentation. In Gradient Vector Flow (GVF) model certain barriers hinder the performance such as weak edge detection, high computational time, limited capture range and its ambiguity with other parameters. In this paper segmentation of Endocardium is carried out on multistage MRI frames Using Adaptive Diffusion flow (ADF) model. This deformable model was tested on large scale number of Cardiac MRI images. We replace the smoothening energy term in GVF with active hyper-surface harmonic minimal function in order to avoid possible leakage at weak edges. The use of harmonic maps is adjusted in accordance with image characteristics. We also assimilate infinite Laplace function to move active contours into narrow concave sections. Experimental results and collation with GVF are presented in this paper which reveals several good results based on extraction of endocardium tissue from left and right ventricle, including less computational time, noise robustness and weak edge preserving on Cardiac MR Images.

Study on non-linear static behavior of 2D low-rise RCC framed structure subjected to progressive collapse

Sheikh, Tariq Ahmad,Banday, J.M.,Hussain, Mohammed A. Techno-Press 2021 Advances in computational design Vol.6 No.4

In this study, the progressive collapse behavior (full load and displacement control methods) of low-rise models representing 2-bay2storey and 3-bay3storey reinforced concrete framed structures located in high seismic zone, designed by Indian codes(IS 456:2000 and IS 1893-2016)for envelope loading combination are assessed with and without U.S. General Services Administration (GSA) guidelines. For displacement-controlled mechanism, a target displacement of 2%, 4% and 5% of the height of structure are considered. Non-linear static behavior of the structure is investigated through (a) Hinge formation pattern (b) Displacement of Joints adjacent to removed column along x-axis and z-axis(c) and Pushdown capacity curves. The results indicate that the Hinge formation patterns are similar for envelope loading combination and GSA loading combination, and the accuracy of the displacement-controlled method is much remarkable compared to full load method, therefore a standard formula is obligatory for calculating the target displacement to control progressive collapse, based on structural requirements unlike the dynamic increase factor calculations based on the structural capacity. With increase in each span and height of structure consecutively, pushdown capacity curves indicate that the base shear increases approximately by two times whereas the displacement in downward direction reduces by 59% and 62.4% for corner column removal and middle column removal cases respectively.

Rashid, Haroon,Alam, Khursheed,Afroze, Dil,Yousuf, Adfar,Banday, Manzoor,Kawoosa, Fizalah Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.6

Gastric cancer (GC) is the fourth most prevalant cancer and the second leading cause of cancer-related mortality worldwide. As in other cancers gastric carcinogenesis is multifactorial involving environmental, genetic and epigenetic components. Epigenetic silencing due to hypermethylation of tumour suppressor genes is one of the key events in gastric carcinogenesis. This study was aimed to analyse the hypermethylation status of the E-Cadherin (CDH1) gene promoter in GCs in the ethnic Kashmiri population. In this study a total of 80 GC patients were recruited. Hypermethylation in tumour tissue was detected by methylation specific PCR (MS-PCR). Hypermethylation of CDH1 promoter was observed in 52 (65%) of gastric carcinoma cases which was significantly much higher than adjacent normal tissue [$p{\leq}0.0001$]. Further the frequency of CDH1 promoter methylation was significantly different with intestinal and diffuse types of gastric cancer [55.7% vs 82.1%; p<0.05]. Moreover females and cases with lymph node invasion had higher frequencies of CDH1 hypermethylation [$P{\leq}0.05$]. Thus the current data indicate a vital role of epigenetic alteration of CDH1 in the causation and development of gastric cancer, particularly of diffuse type, in our population.

Mir, Manzoor R.,Shabir, Nadeem,Wani, Khursheed A.,Shaffi, Sheikh,Hussain, Ishraq,Banday, Manzoor A.,Chikan, Naveed A.,Bilal, S.,Aejaz, Sheikh Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.1

The aim of this study was to evaluate the methylation status of three important cancer related genes viz. p16, E-cadherin and hMLH1 promoters and to associate the findings with specific dietary habits in Kashmiris, a culturally distinct population in India, with gastric cancer. The study subjects were divided into three age groups viz. 0-30yrs ($1^{st}$), 31-60yrs ($2^{nd}$) and 61-90yrs ($3^{rd}$). A highly significant association between the intake of local hot salted tea in $2^{nd}$ (p=0.001) and $3^{rd}$ (p=0.009) age groups was observed with the promoter hypermethylation of E cadherin. Again a highly significant association between the aberrant methylation of hMLH1 (p=0.000) and p16 (p=0.000) promoters and the intake of local hot salted tea was observed in the $2^{nd}$ age group of gastric cancer patients. The intake of sun-dried food was also significantly associated with the promoter hypermethylation of E cadherin (p=0.003) and p16 (p=0.015) genes in $3^{rd}$ age group. The results of the present study suggest a close association between the aberrant methylation of p16, E-cadherin and hMLH1 promoters and the intake of local hot salted tea and sun-dried foods in Kashmiri population.

POWER ASYMMETRY IN WMAP AND PLANCK TEMPERATURE SKY MAPS AS MEASURED BY A LOCAL VARIANCE ESTIMATOR

Akrami, Y.,Fantaye, Y.,Shafieloo, A.,Eriksen, H. K.,Hansen, F. K.,Banday, A. J.,Gorski, K. M. University of Chicago Press for the American Astro 2014 ASTROPHYSICAL JOURNAL LETTERS - Vol.784 No.2

We revisit the question of hemispherical power asymmetry in the WMAP and Planck temperature sky maps by measuring the local variance over the sky and on disks of various sizes. For the 2013 Planck sky map we find that none of the 1000 available isotropic Planck 'Full Focal Plane' simulations have a larger variance asymmetry than that estimated from the data, suggesting the presence of an anisotropic signature formally significant at least at the 3.3 sigma level. For the WMAP 9 year data we find that 5 out of 1000 simulations have a larger asymmetry. The preferred direction for the asymmetry from the Planck data is (l, b) = (212 degrees, -13 degrees), in good agreement with previous reports of the same hemispherical power asymmetry.

To standardize the methodology for in vitro callusing and regeneration of two chrysanthemum cultivars, ‘Candid’ and ‘Flirt,’ an experiment was carried out. The petals and leaf segments were used as explants. In both cultivars, petals were shown to be the most effective for callusing and regeneration. In both cultivars, MS medium enriched with 1.00 mg L−1 BAP + 1.50 mg L−1 NAA resulted in the best callusing of petal explants in terms of minimal days to callus initiation, maximal callus induction, and callus weight per explant. When using petal explants from both cultivars, the shortest time (13.25 and 16.00 days) to callus initiation, the highest callus induction (91.66 and 83.33%) and the highest mean callus weight (2.43 and 2.31 g per explant) were all found in media augmented with 1.00 mg L−1 BAP + 1.50 mg L−1 NAA. In both cultivars, MS media supplied with 1.00 mg L−1 Kinetin + 0.50 mg L−1 IAA resulted in the best regeneration of petal explants in calli-producing shoots and shoot number per explant. Maximum calli-producing shoots 89.58 and 87.49% and significantly maximum shoot number 3.25 and 2.75 per explant were noticed in media fortified with Kinetin 1.00 mg L−1 + IAA 0.50 mg L−1 in case of petal explants of both the cultivars. Nevertheless, the finest callusing of leaf explants in terms of minimum days to callus initiation, highest callus induction in both cultivars was achieved using MS media supplied with 1.00 mg L−1 BAP + 1.50 mg L−1 NAA, whereas the highest callus weight per explant was acquired using MS media supplied with 0.50 mg L−1 BAP and 2.50 mg L−1 NAA. Explants from both cultivars showed a minimum callus initiation period of 15.25 and 16.75 days, callus induction rates of 89.57 and 81.24%, and maximum mean callus weights of 0.94 and 0.89 g, correspondingly.
