New Query Lower Bounds for Submodular Function Minimization
No full textWe consider submodular function minimization in the oracle model: given black-box access to a submodular set function f:2^[n] → ℝ, find an element of arg min_S {f(S)} using as few queries to f(⋅) as possible. State-of-the-art algorithms succeed with Õ(n²) queries [Yin Tat Lee et al., 2015], yet the best-known lower bound has never been improved beyond n [Nicholas J. A. Harvey, 2008].
We provide a query lower bound of 2n for submodular function minimization, a 3n/2-2 query lower bound for the non-trivial minimizer of a symmetric submodular function, and a binom{n}{2} query lower bound for the non-trivial minimizer of an asymmetric submodular function.
Our 3n/2-2 lower bound results from a connection between SFM lower bounds and a novel concept we term the cut dimension of a graph. Interestingly, this yields a 3n/2-2 cut-query lower bound for finding the global mincut in an undirected, weighted graph, but we also prove it cannot yield a lower bound better than n+1 for s-t mincut, even in a directed, weighted graph
Antimicrobial Efficacy of Various Concentrations of Bamboo Salt against Enterococcus faecalis and Candida albicans: An in vitro Study
No full textABSTRACT
Sodium hypochlorite (NaOCl) remains the gold standard against which any new endodontic irrigant is compared. But, its inadvertent extrusion beyond the confines of the root canal can be caustic to vital periapical or periodontal tissues. There has been an increase in the use of herbal medicines as irrigants over the last two decades. Bamboo salt is a Korean folk medicine, which shows promising antimicrobial, antioxidant, and anti-inflammatory properties. The aim of this in vitro study was to comparatively evaluate the effectiveness of 1, 3, and 5% bamboo salt against Enterococcus faecalis and Candida albicans using agar diffusion test; 4% NaOCl was used as control. The experiment was performed in triplicate and the zone of inhibition (ZOI) was measured. The results of the present study showed that 4% NaOCl and 5% bamboo salt showed significantly higher mean ZOI than the other groups against E. faecalis; 4% NaOCl showed significantly higher mean ZOI than the other groups against C. albicans, followed by 5 and 3% bamboo salt. Hence, it can be concluded that 4% NaOCl proved to be the most effective antimicrobial against both the species; 5% bamboo salt was as effective as 4% NaOCl against E. faecalis, but significantly less effective against C. albicans.

Detection of genetically modified cotton seeds using PCR and real-time PCR
No full textDetection of genetically modified (GM) crops and products are necessary to comply with international labeling regulations and to avoid spurious and unapproved GM planting. DNA based analytical tools involving PCR and real-time PCR were used to detect GM cotton seeds. Four pairs of primers specific for CaMV 35S, Nos, nptII and cry1Ac genes were used for the DNA detection of GM crop. The limit of detection in real-time PCR was found to be 0.1%. Evidently, these two PCR techniques were successful in detecting transgenes in the DNA of GM cotton seeds.S. Shree Vidhya, P.H. Ramanjini Gowda; K.N. Yogendra; T.M. Ningaraju and T. Salom
Smart Prevention System to Protect Women Incensorious Situation
No full textIn today's world, people using smart phones have increased rapidly and hence, a smart phone can be used efficiently for personal security or various other protection purposes. Children and women are facing many security related problems. In such situations, they are helpless and don't have any way to protect them or inform it to their family members, neighbours or police station and they feel as handicaps. Hence there should be a system to protect them in such times. This paper presents Shake Alert, an Android Application for the Safety of Women and this app can be activated by a shake, whenever need arises. For that, the system contains GPS to detect location and GSM mechanisms to pass their current location to their trusted contacts as a google map link and services are provided to track the locations to save the person. The unique feature of this application is to send the message to the registered contacts and they can also view the nearby police station with their contact information. Vidhya. S | Shema. N | Reena.

Towards Understanding the Development of Breast Cancer: The Role of RhoJ in the Obesity Microenvironment
No full textObesity is a growing pandemic with an increasing risk of inducing different cancer types, including breast cancer. Adipose tissue is proposed to be a major player in the initiation and progression of breast cancer in obese people. However, the mechanistic link between adipogenicity and tumorigenicity in breast tissues is poorly understood. We used in vitro and in vivo approaches to investigate the mechanistic relationship between obesity and the onset and progression of breast cancer. In obesity, adipose tissue expansion and remodeling are associated with increased inflammatory mediator’s release and anti-inflammatory mediators’ reduction.. In order to mimic the obesity micro-environment, we cultured cells in an enriched pro-inflammatory cytokine medium to which we added a low concentration of beneficial adipokines. Epithelial cells exposed to the obesity micro-environment were phenotypically transformed into mesenchymal-like cells, characterized by an increase in different mesenchymal markers and the acquisition of the major hallmarks of cancerous cells; these include sustained DNA damage, the activation of the ATR-Chk2 pathway, an increase in proliferation rate, cell invasion, and resistance to conventional chemotherapy. Transcriptomic analysis revealed that several genes, including RhoJ, CCL7, and MMP9, acted as potential major players in the observed phenomenon. The transcriptomics findings were confirmed in vitro using qRT-PCR and in vivo using high-fat-diet-fed mice. Our data suggests RhoJ as a potential novel molecular driver of tumor development in breast tissues and a mediator of cell resistance to conventional chemotherapy through PAK1 activation. These data propose that RhoJ is a potential target for therapeutic interventions in obese breast cancer patients
An integrated spatial snap-shot monitoring method for identifying seasonal changes and spatial changes in surface water quality
No full textSummaryIntegrated catchment-scale management approaches in large catchments are often hindered due to the poor understanding of the spatially and seasonally variable pathways of pollutants. High-frequency monitoring of water quality at random locations in a catchment is resource intensive and challenging. A simplified catchment-scale monitoring approach is developed in this study, for the preliminary identification of water quality changes – Integrated spatial snap-shot monitoring (ISSM). This multi-parameter monitoring approach is applied using the isotopes of water (δ18O-H2O and δD) and nitrate (δ15N-NO3− and δ18O-NO3−) together with the fluxes of nitrate and other solutes, which are used as chemical markers. This method involves selection of few sampling stations, which are identified as the hotspots of water quality changes within the catchment. The study was conducted in the peri-alpine Thur catchment in Switzerland, with two snap-shot campaigns (representative of two widely varying hydrological conditions), in summer 2012 (low flow) and spring 2013 (high flow). Significant spatial (varying with elevation) and seasonal changes in the sources of water were observed between the two seasons. A spatial variation of the sources of nitrate and the solute loads was observed, in tandem with the land use changes in the Thur catchment. There is a seasonal shift in the sources of nitrate, it varies from a strong treated waste water signature during the low flow season to a mixture of other sources (like soil nitrogen derived from agriculture), in the high flow season. This demonstrates the influence of other sources that override the influence of waste water treatment plants (WWTPs) during high flow in the Thur River and its tributaries. This method is expected to be a cost-effective alternative, providing snap-shots, that can help in the preliminary identification of the pathways of solutes and their seasonal/spatial changes in catchments
Epic legacies: Hindu cultural nationalism and female sexual identities in India 1920-1960
No full textPhDThe thesis investigates the cultural interventions of Hindu nationalist, C. Rajagopalachari (CR), by
offering a close reading of his re-tellings of the Hindu epics, The Mahabharata (1951) and The
Ramayana (1956). It positions them alongside the writings of M. K. Gandhi and the key responses to
Katherine Mayo’s controversial text Mother India (1927). The thesis explores the central female
protagonists of the epics – Sita and Draupadi – asking how these poetic representations illuminate the
ways in which femininity was imagined by an influential Hindu ideologue during the early years of
Indian Independence.
Using close textual analysis as my principal method I suggest that these popular-literary
representations of sexual identities in Hindu culture functioned as one means by which Hindu
nationalists ultimately sought to regulate gender roles and modes of being. I focus on texts emerging
in the years immediately before and after Independence and Partition. In this period, I suggest, the
heroines of these versions of the epic texts are divested of their bodies and of their mythic powers in
order to create pliant, de-sexualised female icons for women in the new nation to emulate.
Through an examination of the responses to Katherine Mayo’s Mother India (1927), and of Gandhi’s
writings, I argue that there one can discern an attempt in the Hindu Indian script to define female
sexual identity as maternal, predominantly in service to the nation.
These themes, I argue, were later articulated in CR’s recasting of the Hindu epics. CR’s epics
represent the vision of gender within Hindu nationalism that highlights female chastity in the epics,
elevating female chastity into an authentic and perennial virtue. I argue, however, that these ‘new’
representations in fact mark a re-working of much older traditions that carries forward ideas from the
colonial period into the period of Independence. I explore this longer colonial tradition in the
Prologue, through a textual analysis of the work of William Jones and James Mill.
Thus my focus concerns the symbolic forms of the nation – its mythologies and icons – as brought to
life by an emergent Hindu nationalism, suggesting that these symbolic forms offer an insight into the
gendering of the independent nation. The epics represented an idealised model of Hindu femininity. I
recognise, of course, that these identities are always contested, always unfinished. However I suggest
that, through the recasting of the epic heroines, an idea of female sexuality entered into what senior
Hindu nationalist and Congressman, K.M. Munshi, called ‘the unconscious of India’
Enhancement in Photoconductivity of a-Si thin Films by Annealing and Texturing Technique with the Third Harmonic Output from a Pulsed Nd3+:YAG Laser
No full textAbstractInfluence of the third harmonic pulsed Nd3+:YAG laser on the formation of a polycrystalline-silicon (poly-Si) on a-Si thin film with thickness of 1000nm and 400nm in water and air ambience was investigated. In order to induce texturing of surface along with annealing, laser beam overlap technique with different percentages of spot overlap was used. Crystalline characteristics and electrical characteristics were studied to confirm the extent of crystallization. The crystalline characteristics of the film obtained with the Gaussian and the flat-top beam profiles were comparable for higher percentage of overlapping. Based on the theoretical modeling, the laser treatment without the ablation with the third output from the Nd3+:YAG laser was limited to the a-Si film thickness up to 800 nm. This was in qualitative agreement with the experimental observations
Particle swarm optimized extreme learning machine for feature classification in power quality data mining
No full textThis paper proposes enhanced particle swarm optimization (PSO) with craziness factor based extreme learning machine (ELM) for feature classification of single and combined power quality disturbances. In the proposed method, an S-transform technique is applied for feature extraction. PSO with craziness factor is applied to adjust the input weight and hidden biases of ELM. To test the effectiveness of the proposed approach, eight possible combinations of single and
combined power quality disturbances are assumed in the sampled form and the performance of the proposed approach is investigated. In addition white gaussian noise of different signal-tonoise ratio is added to the signals and the performance of the algorithm is analysed. The results indicate that the proposed approach can be effectively applied for classification of power quality disturbances
