Quantum Hamilton-Jacobi analysis of PT symmetric Hamiltonians

We apply the quantum Hamilton-Jacobi formalism, naturally defined in the complex domain, to a number of complex Hamiltonians, characterized by discrete parity and time reversal (PT) symmetries and obtain their eigenvalues and eigenfunctions. Examples of both quasi-exactly and exactly solvable potentials are analyzed and the subtle differences, in the singularity structures of their quantum momentum functions, are pointed out. The role of the PT symmetry in the complex domain is also illustrated.Comment: 11 page

Benign breast diseases: experience at a teaching hospital in rural India

Background: Though benign breast diseases are very common with nearly 1/3 of women suffering some time during their life time, not many studies have focused on this entity, especially in rural areas. Our teaching hospital situated amongst the villages in rural part of India provided the right background for the study.  Objective: To determine the frequency of benign breast diseases in a teaching hospital situated in the rural setting and to analyze the role of triple assessment in assessing benign breast diseases.Study design: Prospective, descriptive study.Setting: MVJ Medical College and Research Hospital, Hoskote, Bangalore Rural district, Karnataka, India.Method of study: Data including age, complaints, clinical examination, radiological investigations and histopathological diagnosis was collected from patients presenting to the department of surgery with breast complaints. Patients with carcinoma of the breast were excluded from the study.Results: A total of 110 patients were studied between November 2009 to March 2011. Mean age of patients was 28.6 years. Fibroadenoma was the most common diagnosis in 56.4% followed by fibroadenosis in 20.9%. There was one case each of lipoma, tuberculosis and duct ectasia and two cases of atypical ductal hyperplasia. The sensitivity of clinical diagnosis in our study was 91.1% and FNAC was 100% accurate in all patients with fibroadenoma but had a sensitivity of only 78% in the diagnosis of fibroadenosis. Only 3.3% of cases of fibroadenoma were treated conservatively

Comparative Evaluation of Sealing Ability and Osteogenic Potential of Conventional Glass Ionomer Cement and Glass Ionomer Cement Modified with Chitosan and Bioactive Glass: An In Vitro study

AIM OF THE STUDY: The aim of this study was to utilize polarized light microscope for the assessment of the efficacy of CPP-ACP, NovaMin and Amine Fluoride pastes on remineralization of enamel over time. MATERIALS AND METHODS: 40 teeth were used for the study and were divided into 4 groups with 10 teeth each. Remineralization was done by application of CPP-ACP, NovaMin and Amine fluoride in the first 3 group’s respectively following demineralization, while the 4th group (control) received only demineralization. Teeth were sectioned under hard tissue microtome and viewed under polarized light microscope for maximum depth of demineralization. RESULTS: Statistical analysis was done using student’s t-test. Mean value of demineralization were 78.06μm for CPP-ACP, 156.82μm for Novamin, 109.80μm for Amine fluoride and 328.32μm for control group. Although the values were best in CPP- ACP group, there was no statistical significance difference between CPP-ACP and Amine fluoride, and both were better than Novamin. CONCLUSION: The study concluded that CCP-ACP and Amine fluoride were better in remineralization followed by NovaMin

Detection of Malicious Circuitry using Transition Probability Based Node Reduction Technique

In recent years, serious concerns have been raised against the tampering of integrated circuits due to outsourcing of circuits for fabrication. It has led to the addition of malicious circuitry known as Hardware Trojan. In this paper, a transition probability based node reduction technique for faster and efficient Hardware Trojan (HT) detection has been attempted. In the proposed method, the fact that the least controllable and observable nodes or the nodes with least transition probability are more vulnerable as Trojan sites is taken into consideration. The nodes that have lesser activity than the threshold are the candidate nodes. At each candidate node, segmentation is done for further leakage power analysis to detect the presence of Trojans. Experimental results observed on ISCAS’85 and ISCAS’89 benchmark circuits illustrate that the proposed work can achieve remarkable node reduction upto 78.81% and time reduction upto 58.7%. It was also observed that the circuit activity can be increased by varying the input probability. Hence, for further reduction in the Trojan activation time, the weighted input probability was obtained

Studies on Heterosis and Combiing Ability for Yield and Quality Attributing Traits in Chilli (Capsicum Annum L.)

Seven lines and four testers were crossed in line x tester mating design to evolve twenty-eight hybrids. These hybrids were studied along with their eleven parents for estimation of relative heterosis, heterobeltiosis and standard heterosis for Fruififteen characters. Observations were recorded on fifteen economically important traits viz., days to 50 percent flowering, plant height at maturity, plant spread, fruit length, fruit width, fruit pedicel length, placenta length, number of fruits per plant, fruit weight, number of seeds per fruit, 1000 seed weight, fruit yield per plant, ascorbic acid content, capsaicin content and capsanthin content. The hybrids L4 x T3 (LCA 625 × G-4) is the best hybrids followed by L7 x T4 (Pant C-1 × LCA 678) and L7 x T2 (Pant C-1 × K1) recorded significant standard heterosis for fruit yield per plant. Selection of hybrids for heterosis breeding based on per se performance, sca effects and standard heterosis will be more effective. It may be concluded that based on all the three criteria, the following three hybrids L4 x T3 (LCA 625 × G-4) and L7 x T4 (Pant C-1 × LCA 678) and L7 x T2 (Pant C-1 × K1) were identified as the superior hybrids, among the twenty-eight hybrids evaluated

Diet and Diabetic Kidney Disease: Plant Versus Animal Protein

PURPOSE OF REVIEW: The goal of this review is to present an overview of the evidence on the effectiveness of plant-based diets in delaying progression of diabetic kidney disease (DKD). RECENT FINDINGS: The ideal quantity of dietary protein has been a controversial topic for patients with DKD. Smaller studies have focused on protein source, plant versus animal, for preventing progression. Limited evidence suggests that dietary patterns that focus on plant-based foods, those that are lower in processed foods, or those that are lower in advanced glycation end products (AGE) may be useful in prevention of DKD progression. Increasing plant-based foods, incorporating diet patterns that limit processed foods, or potentially lowering AGE contents in diets may be beneficial for dietary management of DKD. However, dietary studies specifically targeted at DKD treatment are sparse. Further, large trials powered to assess outcomes including changes in kidney function, end-stage kidney disease, and mortality are needed to provide more substantial evidence for these diets

Periodic Quasi - Exactly Solvable Models

Various quasi-exact solvability conditions, involving the parameters of the periodic associated Lam{\'e} potential, are shown to emerge naturally in the quantum Hamilton-Jacobi approach. It is found that, the intrinsic nonlinearity of the Riccati type quantum Hamilton-Jacobi equation is primarily responsible for the surprisingly large number of allowed solvability conditions in the associated Lam{\'e} case. We also study the singularity structure of the quantum momentum function, which yields the band edge eigenvalues and eigenfunctions.Comment: 11 pages, 5 table

Cloud Computing Based Computing System for Women's Higher Education in Isolated Areas

A new chapter in information technology is opened by cloud computing in computer science and engineering education. Understanding the importance of using cloud computing (CC) in institutions of higher learning is the aim of this research. This analysis shows some of the benefits that cloud computing can provide to higher education, assesses some of the most significant challenges that academics may encounter as a result of its implementation, and suggests some initial steps toward its adoption while mitigating the risks associated. Enterprise apps have migrated in large numbers to the cloud in recent years. One of the challenges posed by cloud applications is the challenge of allocating resources to the application to ensure a service level along dimensions like performance, availability, and dependability. To do this, a system based on the infrastructure of governmental bodies, non-governmental organisations (NGOs), academic institutions, and other providers of social services has been established. The results of this analysis demonstrate that it is possible to use a few variables, including administrative bodies and governments, internal stakeholders, cloud suppliers, firm attributes, socio-political changes, IT framework, and others, to understand how CC adoption methodologies are used in higher education institutions. In addition to providing insight into how cloud providers, advisers, governments, and academics see various market demands and how they respond to these expectations while expanding services provided by CC in higher education institutions, this analysis opens opportunities for future research. The implications for practice can aid decision-makers in utilizing CC services legally

Effects of Excessive Dietary Phosphorus Intake on Bone Health

PURPOSE OF REVIEW: The purpose of this review is to provide an overview of dietary phosphorus, its sources, recommended intakes, and its absorption and metabolism in health and in chronic kidney disease and to discuss recent findings in this area with a focus on the effects of inorganic phosphate additives in bone health. RECENT FINDINGS: Recent findings show that increasing dietary phosphorus through inorganic phosphate additives has detrimental effects on bone and mineral metabolism in humans and animals. There is new data supporting an educational intervention to limit phosphate additives in patients with chronic kidney disease to control serum phosphate. The average intake of phosphorus in the USA is well above the recommended dietary allowance. Inorganic phosphate additives, which are absorbed at a high rate, account for a substantial and likely underestimated portion of this excessive intake. These additives have negative effects on bone metabolism and present a prime opportunity to lower total phosphorus intake in the USA. Further evidence is needed to confirm whether lowering dietary phosphorus intake would have beneficial effects to improve fracture risk
