Fast Computing DFT Method for Sparse Signals Based on Downsampling

Fast Fourier transform (FFT) costs O(N log N) for transforming a signal of length N. Previously researchers introduced the sparse fast Fourier transform (sFFT) with computational complexity O(K log N) for exactly K-sparse signal and O(K log N log(N K)) for generally K-sparse signal. In this paper, a new method to fast compute DFT of generally sparse signals is presented. Firstly, the original signal is downsampled with different time shifts, and the discrete Fourier Transforms (DFTs) of downsampled signals are calculated by FFT. Then the DFTs are used to determine and measure the K non-zero (significant) freq. grids by combining the moment preserving problem (MPP) with the BigBand method. The proposed method is hardware-friendly, and simulation results show that proposed method has better recovery performance compared with other methods.
EFFECTOF ESTROGENADMINISTATIONON THE STRUCTURE OF TESTIS IN THE NEONATAL ALBINO RATS

Environmental contaminants with estrogenic properties increased the concern about their possible role in inducing adverse health effects. Brief exposure of rodents to high doses of natural estrogens in early life results in permanent alterations of the male reproductive organs, but the question of whether environmentally relevant doses can cause the same effects remains controversial (Putz et al., 2001).
Regional Development for a Disastrous Country

The purpose of this paper is to explore the relationship between social and economic factors on the economic loss and number of victims of natural disaster occurring in Indonesia using a pooled data from 2004 to 2008 of all provinces. This study found income as measured by GDRP per capita have negative impact on the number of deaths as well as in the number of houses destroyed. It also suggests that the impact of natural disasters can be lowered by enhancing not only economic development but also human development. Therefore, regional development should consider both of developments in order to reduce the impact of natural disasters. Other important finding of this study is the positive impact of government expenditure on the disaster impact related to the number of deaths. It means that large local government expenditure will not guarantee the regions in reducing the impact of natural disasters. The positive impact of government size on the disaster impact is an interesting topic for a further study that may be related to other issue such corruption in the distribution of aid regarding disasters. The study also suggests that further research may use other appropriate indicator of human development in estimating the benefit of human quality in reducing the impact of natural disaster.

Visibility of unstable oscillation modes in a rapidly rotating B star

Context. Space missions like CoRoT and Kepler have provided numerous new observations of stellar oscillations in a multitude of stars by high precision photometry. The identification of the photometrically observed oscillations is, however, difficult and requires detailed model calculations of pulsating stars. Aims. This work compares the observed rich oscillation spectrum of the rapidly rotating B3 IV star HD 43317 with the first results obtained by a new method to calculate unstable oscillation modes in rapidly rotating stars in order to see whether some of the observed modes can be identified. Methods. The new numerical method consists of two parts. We first search for modes resonant with a prescribed forcing symmetry by moving through relevant regions of complex frequency space and monitoring any increase of the stellar response to the applied forcing and zooming in onto the resonance. These resonant non-adiabatic 2D-solutions are then fed into a 2D relaxation code with the same equations but without forcing terms. The complex oscillation frequency used in the forcing is now no longer prescribed, but added as an extra unknown. The corresponding free oscillation mode is usually obtained after a few (<10) iterations with only minor adjustment of the complex oscillation frequency. To compare with the observed light variations we calculate the “visibility” of the found unstable oscillation modes, taking into account the cancellation of the various parts of the radiating oscillating stellar surface as seen by the observer. Results. The frequencies of unstable axisymmetric g-modes, which have the highest visibility, appear to nearly coincide with the observed largest amplitude photometric variations of HD 43317, making an identification of the latter oscillations as m = 0 modes plausible. The identification of m = 1 g-modes is less straightforward, while many of the unstable even m = 2 g-modes may correspond to observed weaker photometric variations. Only one unstable r-mode has non-negligible visibility. The observationally inferred almost equidistant period spacings of ten, respectively seven, oscillation frequencies for HD 43317 cannot be reproduced.
Risk Factors for Asthma Hospitalization among Adults and Elderly

Joint effect of biological (pollen) and chemical air pollutants on asthma emergency room (ER) visits was analyzed for Szeged region of Southern Hungary. Our database of a nine-year period (1999-2007) includes daily number of asthma emergency room (ER) visits, and daily mean concentrations of CO, PM 10 , NO, NO 2 , O 3 and SO 2 , furthermore two pollen variables (Ambrosia and total pollen excluding Ambrosia), as well. The analysis was performed for ER visits of asthma bronchiale using two age groups (adults and the elderly) of males and females for three seasons. Factor analysis was performed in order to clarify the relative importance of the pollutant variables affecting asthma ER visits. Asthma ER visits denote notably stronger associations with the pollutants in adult male than in adult female patients both for the pollen season of Ambrosia and the pollen-free season. Furthermore, adults are substantially more sensitive to severe asthma attack than the elderly for the season of total pollen excluding Ambrosia pollen. The joint effect of the chemical and pollen variables is the highest for the asthma ER cases in the pollen season of Ambrosia, basically due to the extra impact of the total pollen excluding Ambrosia pollen and partly due to Ambrosia pollen. A nonparametric regression technique was applied to discriminate between events of ER visit – no ER visit using pollen and chemical pollutants as explaining variables. Based on multiple correlations, the strongest relationships between ER visits and pollutants are observed during the pollen-free season. The elderly group with asthma bronchiale is characterized by weaker relationships between ER visits and pollutants compared to adults. Ratio of the number of correct decisions on the events of ER visit – no ER visit is lowest for the season of total pollen excluding Ambrosia pollen. Otherwise, similar conclusions hold as those received by multiple correlations.
Isolating the anthropogenic component of Arctic warming

Structural equation modeling is used in statistical applications as both confirmatory and exploratory modeling to test models and to suggest the most plausible explanation for a relationship between the independent and the dependent variables. Although structural analysis cannot prove causation, it can suggest the most plausible set of factors that influence the observed variable. We apply structural model analysis to the annual mean Arctic surface air temperature from 1900 to 2012 to find the most effective set of predictors and to isolate the anthropogenic component of the recent Arctic warming by subtracting the effects of natural forcing and variability from the observed temperature. We find that anthropogenic greenhouse gases and aerosols radiative forcing and the Atlantic Multidecadal Oscillation internal mode dominate Arctic temperature variability. Our structural model analysis of observational data suggests that about half of the recent Arctic warming of 0.64 K/decade may have anthropogenic causes.
Variations on the Use of a Pictorial Alternative Communication System with a Child with Autism and Developmental Delays

Abstract As aberrant behavior is often recognized as the number one form of communication, it becomes imperative that as parents, teachers, and educators we must address and system-atically teach or provide all children with an effective means of communication. While many augmentative and alternative communication systems such as manual sign lan-guage and the Picture Exchange Communication System (Frost & Bondy, 1994) have shown tremendous success, some students with developmental disabilities students unique needs require more individually tailored communication training that necessitates empirical inquiry and use of collective expertise. Doing so may facilitate the acquisition of skills and behaviors that improve communication skills through independent appropri-ate means for meeting students’ personal needs and desires. This article systematically provides a variation of the Picture Exchange Communication System (PECS) including materials, resources, and methodology necessary to implement similar pictorial augmen-tative and alternative communication systems.
Comparative breeding performance of Marsh Harriers Circus aeruginosus along a gradient of land-use intensification and implications for population management

Assessing variation in breeding performance in relation to habitat characteristics may provide insights into predicting the consequences of land-use change on species ecology and population dynamics. We compared four Marsh Harrier Circus aeruginosus populations subject to similar environmental conditions, but which differed in habitat composition, ranging from natural habitats to intensively cultivated areas. Using a 6-year dataset, we characterized breeding habitat and diet in these four study sites, and analysed breeding performance in relation to this gradient of land-use intensification. There was minimal variation in breeding performance between study years but consistent variation between study sites. Unexpectedly, Marsh Harriers breeding in intensively cultivated habitats had higher reproductive success than those breeding in more natural habitats, which, however, hosted higher breeding densities, so overall net population productivity (fledglings per unit area) was similar across sites. This resulted from combined effects of density-dependence and different predation rates between study sites. The colonization of intensive farmland habitats may not necessarily impact negatively on population sustainability when breeding success and population density are traded against each other. However, our findings should not mask longer-term conservation issues for populations breeding in these intensively managed areas, and further studies should assess potential long-term negative effects of occupancy of human-altered habitat.

Didactic considerations of vocabulary breadth and depth in EFL/ESL contexts - a literature review

This literature review analyzes and synthesizes current studies on the relationship between vocabulary knowledge and reading comprehension in the context of English as a foreign or second language (EFL/ESL). It concludes that vocabulary knowledge is important to reading comprehension. There are some aspects which learners, teachers, curriculum designers, textbook writers and researchers should pay attention to. Both the knowledge of vocabulary breadth and vocabulary depth are important to reading comprehension in EFL/ESL contexts; EFL/ESL language teachers need to focus on mid-frequency vocabulary while carrying out vocabulary instruction for promoting reading comprehension performance; teachers should apply different classroom activities and teaching methods to meet the needs of their students. These issues will be reviewed and discussed in the following article.
Effects of land use changes on kinetics of potassium release in sweetpotato garden soils of the highlands, Papua New Guinea

0.01 M CaCl2 and K release data was fitted to four mathematical models: first order, power, parabolic diffusion and Elovich equations. Results showed two distinct parts in the K release curves and 58–80 % of total K were released to solution phase within 76 h (first 5 extractions) with 20–42 % K released in the later parts (after 76 h). Soils from older gardens which were subjected to intensive and prolonged land use showed sig10
Stress Analysis of a Borehole in Saturated Rocks Under in situ Mechanical, Hydrological and Thermal Interactions

Abstract A novel approach is developed to represent coupled thermal-hydraulic-mechanical (THM) behavior of porous systems that incorporates the non-isothermal free and forced convection of a single component fluid in a non-boiling thermoelastic medium. The three-way simultaneous coupling between the THM triplet is currently linear, but no restriction is placed on incorporating material nonlinearities. The coupled PDEs are solved in space by grid-adaptive finite elements. The model is validated against solutions for linear non-isothermal consolidation of a column. We demonstrate the utility of the model by analyzing the behavior of a deep wellbore in a themoelastic medium circulated by a pressurized, but chilled fluid. Model results illustrate the significant importance of the cross-couplings between individual THM processes for the evaluation of wellbore stability.
Reconnaissance Pb-Pb dating of single mineral phases by the step-leaching method: results from the Caledonides of East Greenland

Reconnaissance Pb-Pb step-leaching analyses have been carried out on garnet and kyanite from the Krummedal supracrustal sequence in East Greenland, yielding respectively Neoproterozoic and Caledonian ages. These data support previous analyses suggesting that the Krummedal supracrustal sequence, widespread in southern parts of the East Greenland Caledonides, was affected by both an early Neoproterozoic and a Caledonian thermal event. Titanite and apatite fractions from the underlying crystalline basement rocks were analysed in order to obtain metamorphic ages, as a contrast and supplement to the numerous existing protolith ages on orthogneisses. The titanite yielded a date of 486 ± 15 Ma which, if interpreted as a true age, is older than the usual range of Caledonian ages in East Greenland. The significance of this date is uncertain, but one possibility is that it reflects extension and subsidence taking place prior to Caledonian collision. The apatite, in contrast, yielded a very young Caledonian date of 392 ± 24 Ma that may reflect the cooling of the basement gneisses to < 500°C subsequent to collision.

The Impact of Parental Level of Income on Students' Academic Performance in High School in Japan

The socioeconomic status of a child parent impacts on the educational development and achievement of the child. This study evaluated the effect of socioeconomic status, specifically parents income and parents-child relationship on student's academic performance in Senior High School in Japan. Three hundred students of Senior High Schools in Osaka and Hyogo prefectures of Japan were randomly selected and used as the sample population. A well-structured questionnaire was used as an instrument for data collection to ascertain the effect of parent's income status and attitude on student's academic performance at school using a four point Likert scale methodology. Academics grade point of students in an examination was also used as the determinant of students' academic achievement. Results showed that greater academic achievement for a student is attained by those students from financially buoyant families (Mean ± SD = 2.97 ± 0.88, X2 = 11.991, P = 0.007), however, 29.7% of students strongly disagree. More than half of respondents (>50%) disagree that financial constraint determines the number of children that goes to school in low income families. Average exam grade (Mean ± SD) points for students from parents with high, medium and low-income status was 77.29 ± 13.1, 77.9 ± 23.3 and 80.79 ± 10.13, respectively (P > 0.05). In conclusion, our finding show parents involvement in children school activities matter most than the parent's financial status in uplifting the children academic performance in school. Our recommendation is that parents should always encourage their children and provide moral support as well for the child to be emotionally stable and have confidence in their academic pursuit to achieve excellence.
Some counterintuitive dependencies of tropical cyclone frequency on parameters in a GCM

AbstractHigh-resolution global climate models (GCMs) have been increasingly utilized for simulations of the global number and distribution of tropical cyclones (TCs), and how they might change with changing climate. In contrast, there is a lack of published studies on the sensitivity of TC genesis to parameterized processes in these GCMs. The uncertainties in these formulations might be an important source of uncertainty in the future projections of TC statistics.This study investigates the sensitivity of the global number of TCs in present-day simulations using the Geophysical Fluid Dynamics Laboratory High Resolution Atmospheric Model (GFDL HIRAM) to alterations in physical parameterizations. Two parameters are identified to be important in TC genesis frequency in this model: the horizontal cumulus mixing rate, which controls the entrainment into convective cores within the convection parameterization, and the strength of the damping of the divergent component of the horizontal flow.

Modeling and Simulations of Drug Distribution in the Human Vitreous

We develop a mathematical model for the drug distribution in the vitreous body of a human eye. The drug is injected in the vitreous and used for the treatment of retinal diseases. For an optimal effect the drug is supposed to stay as long as possible in a certain area. We model the distribution of the drug with anisotropic diffusion which include the effect of the collagen fibers which have a certain orientation in the vitreous body. In addition to the diffusion we include also the steady permeating flow of the aqueous humor and model it with the Darcy equation driven by a pressure drop. The simulations are performed with the Finite Element method. Therefore, the geometry of the vitreous and a grid is constructed. The discretization is realized by using the Crank-Nicolson scheme in time, the Raviart-Thomas elements for the velocity, discontinous zero-order elements for the pressure and Lagrange elements for the concentration. The position of injection is analyzed by introducing specific output functionals which measure the mean or relative amount of the drug in the vitreous and in the area of action. Our simulations show that the injections should be located in the center of the vitreous body for a more efficient therapy.
