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

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

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

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.

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

Geochemical and isotopic signatures for the identification of seawater intrusion in an alluvial aquifer

Seawater intrusion is one of the alarming processes that reduces the water quality and imperils the supply of freshwater in coastal aquifers. The region, north of the Chennai city, India is one such site affected by seawater intrusion. The objective of this study is to identify the extent of seawater intruded area by major geochemical and isotopic signatures. A total of 102 groundwater samples were collected and analysed for major and minor ions. Groundwater samples with electrical conductivity (EC) greater than 5000 μS/cm and a river mouth sample were analyzed for Oxygen-18 (δ 18O) and Deuterium (δ 2H) isotopes to study their importance in monitoring seawater intrusion. The molar ratio of geochemical indicators and isotopic signatures suggests an intrusion up to a distance of 13 km from the sea as on March 2012 and up to 14.7 km during May 2012

Epidemiology of fractures in indoor patients at a tertiary care centre in India: a study of 3000 cases

Background: Implementing appropriate fracture control measures and treatment protocols is crucial to maximizing health and development gains. This requires an in depth understanding of age-specific, sex-specific and cause-specific injury patterns at the national and subnational levels. No such study on fracture epidemiology has been undertaken in the Indian population.Methods: Study was conducted in a tertiary care centre (KEM hospital, Mumbai) which is one of the highest volume trauma centres in the country. Data of 3000 patients was obtained from the medical records department for the year 2016-2019. Patients were segregated with respect to their genders and into three age groups. Etiology of fracture was noted, and fractures classified according to the anatomical area. Whether the patient received conservative or operative management was also recorded.Results: 43.83% of the fractures occurred in 18-50 years age group. 41.33% in the above 50 group and only 14.73% in the below 18 age group. Overall male to female ratio was 1.4: 1. Vehicular accident was the most common mode of injury (47.07%) followed by fall from height (21.03%). Proximal femur fractures were the most common accounting for 19.57% of all fractures followed by forearm (10.53%), tibia diaphysis (8.10%). Talus was the least common. 81.07% cases were managed operatively and 18.93% conserved.Conclusions: Our study highlights that Indian epidemiology is unique from our Western counterparts. Population affected is much younger, old age males are affected more than females. Lower limb fractures are more prevalent and road traffic accidents are responsible for almost half the fractures

Genome-wide association mapping of seed oligosaccharides in chickpea

Chickpea (Cicer arietinum L.) is one of the major pulse crops, rich in protein, and widely consumed all over the world. Most legumes, including chickpeas, possess noticeable amounts of raffinose family oligosaccharides (RFOs) in their seeds. RFOs are seed oligosaccharides abundant in nature, which are non-digestible by humans and animals and cause flatulence and severe abdominal discomforts. So, this study aims to identify genetic factors associated with seed oligosaccharides in chickpea using the mini-core panel. We have quantified the RFOs (raffinose and stachyose), ciceritol, and sucrose contents in chickpea using high-performance liquid chromatography. A wide range of variations for the seed oligosaccharides was observed between the accessions: 0.16 to 15.13 mg g-1 raffinose, 2.77 to 59.43 mg g-1 stachyose, 4.36 to 90.65 mg g-1 ciceritol, and 3.57 to 54.12 mg g-1 for sucrose. Kabuli types showed desirable sugar profiles with high sucrose, whereas desi types had high concentrations RFOs. In total, 48 single nucleotide polymorphisms (SNPs) were identified for all the targeted sugar types, and nine genes (Ca_06204, Ca_04353, and Ca_20828: Phosphatidylinositol N-acetylglucosaminyltransferase; Ca_17399 and Ca_22050: Remorin proteins; Ca_11152: Protein-serine/threonine phosphatase; Ca_10185, Ca_14209, and Ca_27229: UDP-glucose dehydrogenase) were identified as potential candidate genes for sugar metabolism and transport in chickpea. The accessions with low RFOs and high sucrose contents may be utilized in breeding specialty chickpeas. The identified candidate genes could be exploited in marker-assisted breeding, genomic selection, and genetic engineering to improve the sugar profiles in legumes and other crop species
