Rectified Differential Cryptanalysis of 16 Round Present

Manoj Kumar, Pratibha Yadav, Meena Kumari
2020 Zenodo  
In this paper, we have suggested rectifications in differential cryptanalysis of ultra-lightweight block cipher PRESENT reduced to 16 rounds. We have shown that proposed differential attack by Wang [3] on 16 round PRESENT can recover at the most 30 subkey bits, although the author has claimed to recover 32 bits of subkey for last two rounds. We have also computed data complexity and success probability for recovering 30 subkey bits accordingly by the differential attack on 16 round PRESENT.

Till now, several methods have been developed for the synthesis of graphene oxide such as micro-mechanical, exfoliation of pyrolytic graphite; CVD, epitaxial growth, etc. Here in this review paper, we have discussed four methods for the synthesis of graphene oxide, namely Brodie's method, Staudenmaier method, Hofmann method, and Hummer's method. Mostly, graphene oxide has been synthesized by graphite oxidation. Because of excellent properties, chemical functionalization and ease of production graphene and its derivatives have made their way to various applications. Few of the applications of graphene oxide like in electronic devices, energy storage devices, biosensors, coating technology, and graphene oxide composites and paper-like materials have also been incorporated into this paper.

2018 Zenodo  
End-stage renal disease (ESRD) can result from a wide variety of different kidney diseases. Currently, 90% of patients reaching CKD have chronic diabetes mellitus, glomerulonephritis or hypertension. With CKD comes a myriad of problems related to the kidney's inability to excrete waste products leads to symptoms of uraemia. The treatments of CKD require dialysis or kidney transplantation. In this review, an attempt has been made to explain the nutritional management of CKD along with various

Saurabh Suman, Pratibha Warwade, Priti Kumari
2020 Journal of Water Engineering and Management  
In the present study Mann-Kendall (MK)/Modified Mann-Kendall (MMK) test, and Sen's slope test were used to determine the trend over the Southern part of Bihar at seasonal and annual time scales for 11 stations using 110 years data (1901-2010). In MMK test all stations in annual and monsoon season showed a significant decrease in rainfall trend at the 10% significance level. The maximum decrease in the magnitude of rainfall observed for the annual season was - 2.861 mm/year followed by monsoon

On the other hand, the maximum increase in rainfall observed for Post monsoon season was 0.225 mm/year and for summer season it was 0.138mm/year during the study period. Spatial trend depicted the Nalanda and Jamui has the greatest reduction of rainfall from the last 110 years. This study will be very helpful for policymakers, agriculturists, and framers to take a decision on water management, crop scheduling and patterns over this region.

Pap smear: A cost effective method of screening of cervical cancer in a tertiary care centre

Pratibha Kumari, Satya Kumari, Sangeeta Pankaj
2020 International Journal of Clinical Obstetrics and Gynaecology  
Cervical cancer is one of the commonest cancer cause of death among women worldwide. >80% of all the cervical cancer cases are found in developing and low-resource countries, because of a lack of awareness and difficulty in running cytology-based screening programs. Conventional Pap smear testing has been the mainstay of most of the screening programs. Cervical cytology screening by Pap smear has been proven to decrease the incidence and mortality of cervical cancer.

Nisha Kumari, Pratibha Devi Sharma
2018 International Journal of Current Microbiology and Applied Sciences  
Pointed gourd (Trichosanthes dioica) is an important vegetable available seasonally. Pointed gourd slices were dried after pre-treatment using a tray dryer. To accomplish this process, raw, osmosed and blanched slices of pointed gourd were subjected to the drying air temperature of 50, 60 and 70 o C in a tray dryer. The drying time of osmosed sample was reduced to 480 minutes as compared to 600 and 840 minutes taken by blanched and raw pointed gourd samples. Drying of osmosed pointed gourd

Anomaly Detection in Audio with Concept Drift using Adaptive Huffman Coding [article]

Pratibha Kumari, Mukesh Saini
2021 arXiv   pre-print
When detecting anomalies in audio, it can often be necessary to consider concept drift: the distribution of the data may drift over time because of dynamically changing environments, and anomalies may become normal as time elapses. We propose to use adaptive Huffman coding for anomaly detection in audio with concept drift. Compared with the existing method of adaptive Gaussian mixture modeling (AGMM), adaptive Huffman coding does not require a priori information about the clusters and can

To control the size of the Huffman tree, we propose to merge clusters that are close to each other instead of replacing rare clusters with new data. This reduces redundancy in the Huffman tree while ensuring that it never forgets past information. On a dataset of audio with concept drift which we have curated ourselves, our proposed method achieves higher area under the curve (AUC) compared with AGMM and fixed-length Huffman trees. The proposed approach is also time-efficient and can be easily extended to other types of time series data (e.g., video).

Multimedia Datasets for Anomaly Detection: A Review [article]

Pratibha Kumari, Anterpreet Kaur Bedi, Mukesh Saini
2022 arXiv   pre-print
Multimedia anomaly datasets play a crucial role in automated surveillance. They have a wide range of applications expanding from outlier objects/ situation detection to the detection of life-threatening events. For more than 1.5 decades, this field has attracted a lot of research attention, and as a result, more and more datasets dedicated to anomalous actions and object detection have been developed. Tapping these public anomaly datasets enable researchers to generate and compare various

This paper presents a comprehensive survey on a variety of video, audio, as well as audio-visual datasets based on the application of anomaly detection. This survey aims to address the lack of a comprehensive comparison and analysis of multimedia public datasets based on anomaly detection. Also, it can assist researchers in selecting the best available dataset for bench-marking frameworks. Additionally, we discuss gaps in the existing dataset and insights for future direction towards developing multimodal anomaly detection datasets.

2017 Applied organometallic chemistry  
Three compounds (1-3) were synthesized, where ethynylferrocene is substituted at different positions of anthracene and anthraquinone, and their biological properties were investigated. Compounds 1-3 were characterized using NMR and mass spectroscopies and confirmed by their single-crystal X-ray structure. They were also characterized from electronic and photophysical properties. All three crystal structures were optimized using density functional theory calculations. The presence of C-H⋅⋅⋅π

The bioactivity of 1-3 was expressed by molecular docking with various cancerous proteins, which participated in progression of cancer. Compound 2 displayed the best interaction with cancer-related Aurora A protein in terms of both binding energy (−10.61 kcal mol −1 ) as well as inhibition constant (16.74 nM). The molecular docking result also coincides with cytotoxicity on cancer cell lines (A375, HeLa) and DNA/protein binding affinity.
