On Characterizing the Data Access Complexity of Programs

Technology trends will cause data movement to account for the majority of energy expenditure and execution time on emerging computers. Therefore, computational complexity will no longer be a sufficient metric for comparing algorithms, and a fundamental characterization of data access complexity will be increasingly important. The problem of developing lower bounds for data access complexity has been modeled using the formalism of Hong & Kung's red/blue pebble game for computational directed acyclic graphs (CDAGs). However, previously developed approaches to lower bounds analysis for the red/blue pebble game are very limited in effectiveness when applied to CDAGs of real programs, with computations comprised of multiple sub-computations with differing DAG structure. We address this problem by developing an approach for effectively composing lower bounds based on graph decomposition. We also develop a static analysis algorithm to derive the asymptotic data-access lower bounds of programs, as a function of the problem size and cache size

Assessment of Inflammatory Markers in Keelvayu Nivarana Churunam (KNC) Supplementation to Carrageenan-Induced Inflammatory Rats

The carrageenan-induced paw edema is a well-defined model of acute inflammation that a variety of inflammatory mediators involves in its development and has wildly been used to evaluate the anti-inflammatory effect of natural products. The results of the current study suggested that KNC possessed anti-inflammatory effects in carrageenan-induced rats. The anti-inflammatory mechanism of KNC may be related to the reduction of oxidative stress markers as MDA, GPx, Catalase and inflammatory markers PGE2, NO2, TNFα, IL6, IL-10, Myloperoxidase and IgM. Furthermore, the protective effect of KNC may result from anti-oxidative effects. Our findings provide new perspectives on the therapeutic use KNC in the management of inflammatory diseases including arthritis. &nbsp

Modeling the Growth of Telemedicine Literature

The study elaborates the current publication trends in the field of telemedicine as well as the application of growth models to forecast future trends with the goal of determining the fitness of growth in publications using exponential, linear, and logistic growth models. The data for the study was downloaded from the Scopus database over a fifteen-year period, from 2005 to 2019. During the period, a total of 45719 publications were found with publication productivity showing an upward trend throughout the period. The results show that the growth of publications fits into the exponential model than linear or logistic models. This study also predicts that by 2025 there will a total of 108268 publications in the field of Telemedicine, as well as progressive research

Adsorption of fluoride ions onto naturally occurring earth materials

Batch sorption system using two naturally occurring earth materials (EM) as adsorbents was investigated to remove fluoride ions from aqueous solution. The system variables studied include initial concentration of the sorbate, agitation time, adsorbent dose, pH, co-ions and temperature. The experimental data fitted well to the Freundlich isotherm. The amount of fluoride ions adsorbed per unit mass of the adsorbent was found to be 0.011 and 0.007 mg/g, at 30 °C from 4 mg/L fluoride solution, for EM1 and EM2 respectively. Thermodynamic parameters such as ΔH°, ΔS° and ΔG° were calculated which indicates that the removal of fluoride ions is an endothermic process. Kinetic studies reveal that the adsorption follows reversible first order kinetics. X-ray diffraction patterns of the adsorbents before and after adsorption and Dubinin-Radushkevick (D-R) isotherm indicate that the adsorption of fluoride ions onto these materials is a physisorption process. @ JASEMJ.

Structure and stability of spiro-cyclic water clusters

The structure and stability of spiro-cyclic water clusters containing up to 32 water molecules have been investigated at different levels of theory. Although there exist minima lower in energy than these spiro-cyclic clusters, calculations at the Hartree-Fock level, density functional theory using B3LYP parametrization and second order Møller-Plesset perturbation theory using 6-31G∗ and 6-311++G∗∗ basis sets show that they are stable in their own right. Vibrational frequency calculations and atoms-inmolecules analysis of the electron density map confirm the robustness of these hydrogen bonded clusters

Observational study of tympanic membrane changes in allergic rhinitis

Background: Allergic rhinitis (AR) is a common condition affecting 20-30% of the population. This condition affects not only the nose but also the sinuses and ears in many ways. Many studies are there worldwide implicating AR as a cause of serous otitis media. But only few studies have actually studied the tympanic membrane (TM) changes observed in patients with allergic rhinitis. The aim of this study is to document the TM changes observed in patients with AR and to correlate them with the duration of symptoms and also influence of prior treatment of AR on the TM changes observed.Methods: A total of 111 patients and so 222 ears were studied. A detailed history of the duration of symptoms and any prior treatment for AR was recorded. The TM changes seen were classified and recorded. The duration of disease and treatment were taken as grouping variables and the tympanic membrane changes were ranked and used as testing variable. The results were statistically analyzed using non- parametric test, Kruskal – Wallis test.Results: There was no statistically significant correlation between duration of AR and the TM changes observed. However there was a significantly less number of patients with TM retraction observed in the patients who had taken prior treatment compared to those patients who had taken no prior treatment.Conclusions: It is concluded that institution of early treatment may prevent development of Eustachian tube dysfunction and TM changes in patients with AR
