Lipomatosis: a diverse form of hemifacial hyperplasia
Arora, Preeti Chawla,Umarji, Hemant R.,Arora, Aman,Ramaswami, Easwaran Korean Academy of Oral and Maxillofacial Radiology 2012 Imaging Science in Dentistry Vol.42 No.3
A case of hemifacial hyperplasia that presented with muscular, skeletal, and dental hyperplasia along with lipomatous infiltration was described. Advanced imaging was useful in identifying the lipomatous infiltration present in the lesion, which raises the possibility of lipomatosis having a diverse presentation in hemifacial hyperplasia. As there was a scarcity of related literature in the field of dentomaxillofacial radiology, this report would make us familiar with its computed tomographic and magnetic resonance image findings.

The Research paper deals with the several facet of image processing like color detection and some applications of it. It will enable you to make gestures with the help of RGBY colors. The colors are detected on the basis of a property named centroid. On the basis of the coordinates of the centroid, apply distance algorithm and get the distance. By varying the distance between the fingers, different gestures can be made which can perform various operations of today’s digital world and also be applied to the industries.
Multicriteria Quadratic Plant Location Problem
Sudha Arora,S.R. Arora 한국경영과학회 2008 Management Science and Financial Engineering Vol.14 No.1
In this paper, we have considered the multicriteria quadratic plant location problem. In addition to the allocation costs, the maintenance costs of the plants are also considered. The objective functions considered in this paper are quadratic in nature. The given problem is reduced to the problem with linear objective function. The method of Fernandez and Puerto (2003) is applied to solve the reduced problem. It is illustrated with help of examples. The effect of the change in the allocation and maintenance costs on allocation of plants to the clients has also been discussed.

Imposition of Nutrient Stress on Soilborne Fungal Pathogens
Arora, D. K. 한국균학회 1991 韓國菌學會誌 Vol.19 No.2
Propagules of soiborne pytopathogenic fungi are subjected to numerous abiotic (soil moisture, temperature, pH, oxygen, radiation, chemicals etc.) and biotic (predation, hyperparasitism, antibiosis etc.). In soil fungal propagules must survive with numerous other microorganisms and compete for available energy (carbon) substrate. The competition for energy substrate influences the ability of fungal inoculum to persist in soil. It is found that enhanced exudation of carbon compounds from fungal propagules may also result from exposure to competitive stress imposed by soil microorganisms. The imposition of mycostasis by nutrient deprivation appears to be related to increased endogenous exudation losses. The loss of 14C-exudation from the fungai inoculum was found to be directly related with germination suppression. This phenamenon was experimentally evaluated imposing the propagules under diffusive stress, in soil and in the presence of specific microorganisms. Greater rate of 14C-exudation was found in soil and in the presence of specific microorganisms than from the propagules exposed to artificial diffusive stress. Loss of endogenous carbon from the fungal propagules has also been directly realated to elevation of nutrient requirements for the germination, progressive loss of viability, formation of persisten structures and decreased aggressiveness. The consequences of imposed stress on propagules have potential significance in the management of soilborne fungal diseases. The cellular mechanism by which biotic or abiotic stress suppresses germination is not known. Possibly, depletion of nutrients from the fungal propagules occurs by enzyme-hydrolysis $quot;sensor$quot; system which depends upon degree of imposed competitive nutrient stress.
miR-9 and let-7g enhance the sensitivity to ionizing radiation by suppression of $NF{\kappa}B1$
Arora, Himanshu,Qureshi, Rehana,Jin, Shunzi,Park, Ae-Kyoung,Park, Woong-Yang Korean Society for Biochemistry and Molecular Bion 2011 Experimental and molecular medicine Vol.43 No.5
The activation of nuclear factor-kappa B1 ($NF{\kappa}B1$) in cancer cells may confer resistance to ionizing radiation (IR). To enhance the therapeutic efficiency of IR in lung cancer, we screened for microRNAs (miRNAs) that suppress $NF{\kappa}B1$ and observed their effects on radiosensitivity in a human lung cancer cell line. From time series data of miRNA expression in ${\gamma}$-irradiated H1299 human lung cancer cells, we found that the expression of miR-9 was inversely correlated with that of $NF{\kappa}B1$. Overexpression of miR-9 down-regulated the level of $NF{\kappa}B1$ in H1299 cells, and the surviving fraction of ${\gamma}$-irradiated cells was decreased. Interestingly, let-7g also suppressed the expression of $NF{\kappa}B1$, although there was no canonical target site for let-7g in the $NF{\kappa}B1$ 3' untranslated region. From these results, we conclude that the expression of miR-9 and let-7g could enhance the efficiency of radiotherapy for lung cancer treatment through the inhibition of $NF{\kappa}B1$.

Pythagorean fuzzy sets (PFSs) are capable of modelling information with more uncertainties in decision-making problems. The essential feature of PFSs is that they are described by three parameters: membership function, non-membership function and hesitant margin, with the total of the squares of each parameter equal to one. The purpose of this article is to suggest some new similarity measures and weighted similarity measures for PFSs. Numerical computations have been carried out to validate our proposed measures. Applications of these measures have been applied to some real-life decision-making problems of pattern detection and medicinal investigations. Moreover, a descriptive illustration is employed to compare the results of the proposed measures with the existing analogous similarity measures to show their effectiveness.
INFERENCE FOR ABSOLUTE LORENZ CURVE AND ABSOLUTE LORENZ ORDERING
Arora Sangeeta,Jain Kanchan,Pundir Sudesh The Korean Statistical Society 2006 Journal of the Korean Statistical Society Vol.35 No.3
Absolute Lorenz curve plays an important role for measuring absolute income inequality. Properties of absolute Lorenz curve are listed. Asymptotically distribution free and consistent tests have been proposed for comparing two absolute Lorenz curves in the whole interval [P1, P2] where 0 < P1 < P2 < 1. Absolute Lorenz ordering has been discussed for some distributions.

Synthesis and spectroscopic characterization of zinc ferrite nanoparticles
Arora, Shefali,Nandy, Subhajit,Latwal, Mamta,Pandey, Ganesh,Singh, Jitendra P.,Chae, Keun H. Techno-Press 2022 Advances in nano research Vol.13 No.5
Synthesis approaches usually affect the physical and chemical properties of ferrites. This helps ferrite materials to design them for desired applications. Some of these methods are mechanical milling, ultrasonic method, micro-emulsion, co-precipitation, thermal decomposition, hydrothermal, microwave-assisted, sol-gel, etc. These methods are extensively reviewed by taking example of ZnFe<sub>2</sub>O<sub>4</sub>. These methods also affect the microstructure and local structure of ferrite which ultimately affect the physical and chemical properties of ferrites. Various spectroscopic techniques such as Raman spectroscopy, Fourier Transform Infrared spectroscopy, Ultra Violet-Visible spectroscopy, Mossbauer spectroscopy, extended x-ray absorption fine structure, and electron paramagnetic resonance are found helpful to reveal this information. Hence, the basic principle and the usefulness of these techniques to find out appropriate information in ZnFe<sub>2</sub>O<sub>4</sub> nanoparticles is elaborated in this review.
