Analysis of criteria for reduced-spaced parallel runway approaches : the potential application of PRM / SOIA in São

1 ANALYSIS OF CRITERIA FOR CLOSELYSPACED PARALLEL RUNWAY APPROACHES: THE POTENTIAL APPLICATION OF PRM/SOIA IN SÃO PAULO INTERNATIONAL AIRPORT Rafael Fraga – ITA, Brazil Carlos Müller – ITA, Brazil Cláudio Jorge Pinto Alves – ITA, Brazil ABSTRACT In order to increase arrival rates at many of today’s heavily congested airports, simultaneous approaches are conducted on parallel runways. For many years, the FAA has recommended simultaneous independent instrument approach operations only for those parallel runways with a minimum distance of 4300 feet. Nowadays, new criteria have been developed to increase the use of parallel runways, one of these procedures, called PRM/SOIA (Precision Runway Monitor/Simultaneous Offset Instrument Approach), make simultaneous approaches possible in systems of runways spaced as close as 750 feet.
A Micromixer with Two-Layer Crossing Microchannels Based on PMMA Bonding Process

Abstract A micromixer with two-layer crossing microchannels based on PMMA bonding process was proposed. The micromixer consists of two-layer crossing microchannels and periodic mixing chambers. The numerical simulation and parameters optimization of the micromixer were carried out in a Reynolds number range of 0.5–100 using CFD software, and the prototype of micromixer was manufactured by PMMA bonding process under certain temperature and pressure condition. The mixing performance of the micromixer was tested and verified by the mixing experiments using red-blue dye. Both the numerical and experimental results confirmed that the micromixer achieves an excellent mixing characteristics over a wide range of Reynolds numbers through generating Dean vortices and chaotic advection. At the same time, the PMMA bonding process proposed in this paper has certain application value and reference significance for expanding the application of three-dimensional flow channels in the field of microfluidics.

Fluid flow through clayey soils: stable isotope and mineralogical evidence

Abstract The evaluation of clays as barriers to fluid movement can be improved by geochemical methods that provide ways to examine the reactivity and weathering of minerals in soils and sediments. X-ray radiography, X-ray powder diffraction, and stable isotope geochemistry provide new data from field locations in the Mississippi River Delta of Louisiana indicating that the clays are not effective barriers to the vertical migration of fluids in the shallow subsurface. Systematic changes in the mineral assemblages, the soil structure and the δD and δ18O values of time clay fractions can best be explained by an alteration sequence produced as the originally smectiterich clay mineral assemblage was kaolinized by percolating groundwater.
Understanding the conformational stability of protein therapeutics using Raman spectroscopy

Raman spectroscopy simultaneously derives protein secondary structure (Amide I and III) and tertiary structure markers (aromatic side chains, disulfide bonds, hydrogen bonding, local hydrophobicity). These higher order structural determinations are performed at actual formulation concentrations (50 mg/mL or greater for mAbs), rather than at the lower concentrations required by conventional methods, i.e. less than a few mg/mL for Circular Dichroism (CD).
Identification and Impact of Insects Feeding on the Stored Seeds of Lagenaria siceraria Molina ( Standl . , 1930 ) and Citrullus lanatus Thumb ( Matsum & Nakai , 1916 ) , two Oilseed Cucurbits of the Ivory Coast

Storage seeds are exposed to a number of stored product insect pests that cause a major decline in grain quality and contribute to global financial losses. This study aimed to identify insects that feed on two cucurbit seed, Lagenaria siceraria and Citrullus lanatus, which are endemic to the Ivory Coast. The seeds were placed in jars and bags, and were kept in a modern store or traditional kitchen. Observations were made on (1) insect richness and (2) species diversity, in parallel to a (3) damage assessment (by evaluating the weight loss, moisture content, and germination rate of the seeds). Sixteen insect species were identified, which belonged to 14 families and 5 orders. Species richness and diversity were significantly (P < 0.001) higher in the kitchen and bags compared to the store and jars. In both the store and kitchen, seeds in bags had significantly higher (P< 0.001) humidity and weight loss rates compared to seeds in jars. Seeds in jars had significantly higher germination rates (P<0.001) compared to seeds in bags. Thus, jars reduce insect proliferations and associated damage to American Journal of Research Communication www.usa-journals.com Adja, et al., 2016: Vol 4(2) 105 seeds (maintaining higher germination rates), and should therefore be preferentially to conserve the seeds of L. siceraria and C. lanatus.

Language Model Classifier Aligns Better with Physician Word Sensitivity than XGBoost on Readmission Prediction

Traditional evaluation metrics for classification in natural language processing such as accuracy and area under the curve fail to differentiate between models with different predictive behaviors despite their similar performance metrics. We introduce sensitivity score, a metric that scrutinizes models' behaviors at the vocabulary level to provide insights into disparities in their decision-making logic. We assess the sensitivity score on a set of representative words in the test set using two classifiers trained for hospital readmission classification with similar performance statistics. Our experiments compare the decision-making logic of clinicians and classifiers based on rank correlations of sensitivity scores. The results indicate that the language model's sensitivity score aligns better with the professionals than the xgboost classifier on tf-idf embeddings, which suggests that xgboost uses some spurious features. Overall, this metric offers a novel perspective on assessing models' robustness by quantifying their discrepancy with professional opinions. Our code is available on GitHub (https://github.com/nyuolab/Model_Sensitivity).
Addicted to Inﬂation? The Chilean Experience of 1970s ∗

In the early 1970s Chile reached an inﬂation level of 600%, which was the highest inﬂation level ever experienced in the history of the country. Based on the results of the Cagan (1956) model, we conclude that after 1973 inﬂation was way above the level that would have maximized seigniorage. Our results suggest that the economy, after 1973, was used to live with high levels of ﬁscal deﬁcits, not reﬂected in the oﬃcial ﬁgures, or was unable to generate credible mechanisms for breaking the inﬂationary spiral of the early 1970s. The economy seem to have entered, after 1973, a period of inﬂation addiction that lasted until the late 1970s.
Influence of Magnetic Iron and K-Humate on Productivity of Valencia Orange Trees (Citrus Sinensis L.) under Salinity Conditions

This study is to evaluate the effect of magnetic iron (500 and 1000g/tree) and k-humate (50 and 100 g/tree) treatments on growth and productivity of Valencia orange trees under reclaimed conditions (sandy soil and saline water), during two successive seasons (2011-012) and (2012-013) at a private orchard in Abu Shalaby El Salhia region, Sharkia Governorate. There was significant improve by the different magnetic iron and K-humate treatments on the growth, tree productivity and fruit quality. The analysis of the data collected during the study proved that there were statistically significant increases in vegetative growth, crop yield, fruit quality and some leaf chemical composition with different doses of magnetic iron and K-humate treatments, Whereas, 1000 g magnetic iron plus 50g K-humate was the best results for vegetative growth, yield production and the fruit quality under this study during both seasons.
Residential segregation and social segregation by race

In this paper, I examine a determinant of social segregation by race in the United States: physical distance. Because U.S. cities are highly segregated, the time cost of interacting with a member of another race is typically higher than the cost of interacting with a same-race friend. The goal of this paper is to quantitatively assess the importance of this channel in explaining why people typically interact with members of their own race. Based on external estimates of consumers’ costs of time, I simulate the frequency of cross-racial interactions that would occur if only distance mattered in determining individuals’ choice of interaction partners. I compare the simulation results to a new measure of the actual frequency of inter-racial interactions based on Flickr photographs. I estimate that 25-30% of social segregation for whites in the U.S. is attributable to physical distance alone. I would like to thank Dwayne Benjamin, Michael Baker and Aloysius Siow, as well as participants in several seminars at the University of Toronto, for their helpful comments on this paper.
EFFECTIVE PLASMA FREQUENCY IN A MAGNETIZED ONE-DIMENSIONAL PLASMA PHOTONIC CRYSTAL

The effective plasma frequency in a photonic crystal is defined as the lowest frequency at which electromagnetic wave can start to propagate through the photonic crystal. In this work, we theoretically investigate the effective plasma frequency fp,eff for a magnetized one-dimensional plasma photonic crystal (PPC). The PPC is made of two constituents, i.e., the plasma and the dielectric material like quartz. The effective plasma frequency in a PPC is obtained based on the calculated photonic band structure (PBS). It is found that fp,eff can be controlled by the externally applied static magnetic field, namely fp,eff decreases significantly as the static magnetic field increases. This suggests that the plasma layer in a PPC shows a dielectric-like behavior when the magnetic field is applied. In addition, in the presence of static magnetic field, fp,eff will be increased as a function of electron density and thickness of the plasma layer. In the angular dependence of effective plasma frequency, we find that fp,eff is a decreasing function of angle of incidence in the absence of the static magnetic field. However, it becomes an increasing function of angle of incidence when the static magnetic field is applied. Finally, the effect of filling factor of the plasma layer is also illustrated. _______________________________ Received 1 July 2012, *Corresponding author: Chien-Jang Wu (jasperwu@ntnu.edu.tw)
The open question of time fractional PDEs: needs to store all data

It is well known that the nunerical solution of time fractional PDEs at current stage depends on all preceding time instances. Hence, the storage requirement grow linearly as the number of the time steps increases, which poses a significant challenge especially for high-dimensional problems. To the best of our knowledge, this is still an open question in the time fractional PDEs. In this paper, we propose an efficient and memory free algorithm to answer this open question by using incremental SVD. Numercial experiemnts show that our new algorithm not only memory free, but also more efficient than standard solvers.
On Technology Choice in Standardization : Implications for Patent Valuation

The valuation of patents included in standards and their reasonable license fees is affected by two competing views about how and why standards are developed. One view, which emphasizes that standardization is foremost about choosing a technical solution, assumes the availability of roughly equivalent alternatives; the other emphasizes that standardization is foremost about picking the best technical solution, assuming distinctly different alternatives. These views affect patent valuations but often remain implicit in economic and legal studies.This paper examines which view is more accurate from the perspective of standardizers using data from expert interviews and literature study. While the study suggests that the availability of roughly equivalent alternatives is generally more accurate, neither view well-captures the reality of standard development. Typically, the relative technical merit of competing solutions is an important selection criterion, but it is secondary to other critical factors. The findings highlight the interrelatedness of the manytechnical design choices usually at stake; the negotiability of and tradeoffs between multiple performance criteria determining the value of technical solutions; the filtering effect of consensus versus voting committees on actual technology choice; and, not least, the influence of non-technical factors on technology choice. Given these caveats, valuating patents-in-standards on their technical, innovative merit will remain contentious. To better account for the influence of the dynamics of standards processes on technology choice, a valuator’s line of reasoning should address, among other factors, existing alternative technical solutions and multiple performance dimensions. Follow-up research is recommended that examines the implications of patent inclusion for these dynamics.
Variable IIR Filters Sections with High Accuracy Independently Tunable Center Frequency and Bandwidth

A new method to design tunable band-pass and band-stop IIR digital filters with higher accuracy of tuning is proposed in this paper. It is based on cascade realization and spectral transformations connected to proper development or selection and design of prototype sections (first and second-order low-pass and high-pass sections and first-order all-pass sections) with minimized sensitivity and canonic number of multipliers. Applying the method, new tunable secondand fourth-order bandpass/band-stop sections with independent tuning of the center frequency and bandwidth and with higher universality are developed and many more may be obtained for different frequency ranges. It is shown that they have much better accuracy of tuning and lower noises compared to all other known similar sections. They permit also implementations with much shorter coefficient word-length, decreasing thus the volume of the computations for coefficient updating and simplifying the adaptive filter applications.
Evaluation for the performance of the Guangdong-Hongkong-Macau Lightning Location System

In this paper, the performance characteristics of the Guangdong-Hongkong-Macau Lightning Location System (GHMLLS) was evaluated based on observations of lightning flashes triggered at the Guangzhou Field Experiment Site for Lightning Research and Testing during 2007-2013, and natural lightning flashes to tall structures in Guangzhou during 20092012. Both experiment sites are located in the center area of the GHMLLS after the upgrade in 2012, but slightly outside of that before 2012. Considering the significant increasing of the number of sensors in 2012, the evaluations were performed according to two different periods of 2007-2011 and 2012-2013 respectively, and the performance characteristics during the two periods were compared. The results show that the flash detection efficiency, stroke detection efficiency, the arithmetic mean value and median value for location error were estimated to be about 64%, 22%, 2 330 m and 1 370 m for triggered lightning during 20072011, while the corresponding values were about 86%, 91%, 590 m and 400 m during 2012-2013. The flash detection efficiency, stroke detection efficiency, the arithmetic mean value and median value for location error were estimated to be about 82%, 58%, 2 820 m and 930 m for natural lightning during 2009-2011, while the corresponding values were about 97%, 90%, 950 m and 470 m during 2012. Directly measurement of peak current of return strokes of triggered lightning was not obtained in 2007 due to various reasons. During 2008 to 2011, for 14 return stroke processes of artificially triggered lightning, both the directly measurement of peak currents and the corresponding GHMLLS records were obtained. 13 out of the 14 peak currents were underestimated by GHMLLS and only one was overestimated, and the absolute percentage errors of peak current estimation were within 16.2% to 96.2%, with arithmetic mean value and median value of about 34% and 26%. On the other hand, during 2012-2013, all the 32 peak currents , both the directly measurement of peak currents and the corresponding GHMLLS records were obtained, were overestimated by GHMLLS, and the absolute percentage errors of peak current estimation ranged from 31% to 421%, with arithmetic mean value and median value of about 217% and 220%. When the number of sensors was significantly increased in 2012, the detection efficiency and location precision of GHMLLS were found to be obviously improved, but the peak currents of return strokes were abnormally overestimated.

EFFECT OF MIXING ON THE RHEOLOGY OF ALUMINA FEEDSTOCKS

This paper examines the effect of mixing conditions, specifically the shear rate, on the homogeneity and rheological characteristics of powder injection molding alumina feedstock. Central to the study of mixing is the hypothesis that homogeneity is imparted to the feedstock during the mixing process and that the homogeneity of a feedstock can be estimated by its rheology. It was observed that an increase in the mixing shear rate decreased the viscosity and the variation of viscosity with time. This was shown to be accompanied by deagglomeration of alumina owing to erosion, that is, a gradual reduction in the agglomerate size during mixing. Experimental and modeling results confirm that viscosity of the feedstock is a good indicator of its homogeneity.
A SEMI-ANALYTICAL ALGORITHM FOR MODELLING COMPTON GAMMA-RAY BEAMS

Compton scattering of a laser beam with a relativistic electron beam has been used to generate an intense, highly polarized, and nearly monoenergetic gamma-ray beam at several facilities. The ability of predicting the spatial and spectral distributions of a Compton gamma-ray beam is crucial for the optimization of the operation of a Compton light source as well as for the applications utilizing the Compton beam. In this paper, we present an analytical algorithm for modelling Compton scattering process. Based upon this algorithm, we developed a numerical integration code to produce smooth results for the spatial and spectral distributions of the Compton beam. This code has been used to characterize the High Intensity Gamma-ray Source (HIγS) at Duke University for varying electron and laser beam parameters as well as different gamma-ray beam collimation conditions.
Identifying G × E or G × G interactions in case of heteroscedasticity using mixture of regression models : application to GWAS

We propose to use mixture of regression models as a tool to detect genotype×environment or genotype×genotype interactions. Indeed, the large majority of the tools used in the literature is based on interaction models. However, interaction models allow to detect interactions supposing an homoscedastic model, contrary to mixture of regression models. The strategy of mixture of regression models is compared with Levene’s test which is well-used to detect interacting SNPs (single nucleotide polymorphisms) based both on simulated data and on a SNP (rs7202116) which shows significant differences of variance of the BMI (body mass index) between its genotypes. Mixture of regression models provide very promising results on simulated data since it outperforms Levene’s test in a large number of situations. Moreover, on the data from a French general population cohort composed of 4570 individuals, mixture of regression models allow to detect a very significant interaction for the SNP rs7202116 contrary to Levene’s test.
Adiposity Related Brain Plasticity Induced by Bariatric Surgery

Previous magnetic resonance imaging (MRI) studies revealed structural-functional brain reorganization 12 months after gastric-bypass surgery, encompassing cortical and subcortical regions of all brain lobes as well as the cerebellum. Changes in the mean of cluster-wise gray/white matter density (GMD/WMD) were correlated with the individual loss of body mass index (BMI), rendering the BMI a potential marker of widespread surgery-induced brain plasticity. Here, we investigated voxel-by-voxel associations between surgery-induced changes in adiposity, metabolism and inflammation and markers of functional and structural neural plasticity. We re-visited the data of patients who underwent functional and structural MRI, 6 months (n = 27) and 12 months after surgery (n = 22), and computed voxel-wise regression analyses. Only the surgery-induced weight loss was significantly associated with brain plasticity, and this only for GMD changes. After 6 months, weight loss overlapped with altered GMD in the hypothalamus, the brain’s homeostatic control site, the lateral orbitofrontal cortex, assumed to host reward and gustatory processes, as well as abdominal representations in somatosensory cortex. After 12 months, weight loss scaled with GMD changes in right cerebellar lobule VII, involved in language-related/cognitive processes, and, by trend, with the striatum, assumed to underpin (food) reward. These findings suggest time-dependent and weight-loss related gray matter plasticity in brain regions involved in the control of eating, sensory processing and cognitive functioning.
