THE BIMA PROJECT: O-C DIAGRAMS OF ECLIPSING BINARY SYSTEMS

The Eclipsing Binaries Minima (BIMA) Monitoring Project is a CCD-based photometric observational program initiated by Bosscha Observatory - Lembang, Indonesia in June 2012. Since December 2012 the National Astronomical Research Institute of Thailand (NARIT) has joined the BIMA Project as the main partner. This project aims to build an open-database of eclipsing binary minima and to establish the orbital period of each system and its variations. The project is conducted on the basis of multisite monitoring observations of eclipsing binaries with magnitudes less than 19 mag. Differential photometry methods have been applied throughout the observations. Data reduction was performed using IRAF. The observations were carried out in BVRI bands using three different small telescopes situated in Indonesia, Thailand, and Chile. Computer programs have been developed for calculating the time of minima. To date, more than 140 eclipsing binaries have been observed. From them 71 minima have been determined. We present and discuss the O-C diagrams for some eclipsing binary systems.
In Situ Hybridization, with or Without Tyramide Signal Amplification, in Evaluation of Human Papillomavirus Status Inearly Stage Cervical Carcinoma

In Situ Hybridization, with or Without Tyramide Signal Amplification, in Evaluation of Human Papillomavirus Status Inearly Stage Cervical Carcinoma Conventional in situ hybridization (CISH) can be used for detection of human papillomavirus (HPV) DNA, enabling preservation of the tissue morphology and assessment of the physical state of viral DNA, but has low sensitivity. This study compared the sensitivity and efficiency of in situ hybridization with tyramide signal amplification (ISH TSA) with those of CISH. The HPV status of 77 cases with early stage cervical carcinoma was evaluated with CISH, using biotinylated probes for HPV types 6/11, 16/18 and 31/33/51, and with ISH TSA using probes for HPV types 6/11, 16/18 and 31/33 or 31/33/51. The HPV DNA was detected in 26 (33.8%) cases using CISH, and in 45 (58.4%) cases using ISH TSA. By adding the TSA step, the sensitivity of CISH was enhanced by 24.7%, thus enabling detection of 20 new HPV-positive cases. Multiple HPV infections were detected in four cases. A dot signal pattern was present in 68.9% (31/45) and more than five positive nuclei per sample were found in 82.2% (37/45) of the cases. We found that the ISH TSA system is a fast and simple method for detection of HPV DNA in cervical carcinoma compared to CISH, and is more sensitive and efficient in the detection and typing of HPV, assessment of HPV DNA physical state and evaluation of the number of positive cells than CISH.
Comparative study of different steganographic techniques

Steganography is the method of hiding data in such a way that no one, except the sender and the intended recipient, expects the existence of the hidden data. Thus the goal here is always to conceal the very existence of the secret data embedded in an innocent data in such a way that it will be undetectable, robust and the innocent data should be able to accommodate high capacity of the secret data. When it comes to the pro and cons of various Steganographic software, many have been designed; each of them has different features and capabilities for data hiding, hence, this makes it a wide and attractive field for further research, in which the establishment of innovative methods and techniques could be done. Different Steganographic techniques were studied; experiment was carried out using five Steganographic software. Finally comparison was done using benchmarking tool for identifying different performance aspects of the Steganographic techniques and Steganographic software like visual quality, performance indices, memory requirement and the evaluation of the maximum capacity for each software under this study. Experimental results show that all the software under this study performs above optimal level, although there are some differences of features and capabilities observed.
A Simple Photometer and Chemometrics Analysis for Quality Control of Sambiloto (Andrographis paniculata) Raw Material

In this paper, we described the use of a light emitting diode (LED)-based photometer and chemometric analysis for quality control of king of bitter or sambiloto ( Andrographis paniculata ) raw material. The quality of medicinal plants is determined by their chemical composition. The quantities of chemical components in medicinal plants can be assessed using spectroscopic technique. We used an “in house” photometer to generate spectra of sambiloto . The spectra were analyzed by chemometric methods, i.e. principal component analysis (PCA) and partial least square discriminant analysis (PLS-DA), with the aim of herbal quality classification based on the harvesting time. From the results obtained, based on thin layer chromatography analysis, sambiloto with different collection times (1, 2, and 3 months) contained different amounts of active compounds. Evaluation of sambiloto , using its spectra and chemometric analysis has successfully differentiated its quality based on harvesting time. PCA with the first two PC’s (PC-1 = 60% and PC-2 = 35%) was able to differentiate according to the harvesting time of sambiloto. Three models were obtained by PLS-DA and could be used to predict unknown sample of sambiloto according to the harvesting time
Influence of biological carbon export on ocean carbon uptake over the annual cycle across the North Pacific Ocean

We evaluate the influences of biological carbon export, physical circulation, and temperature‐driven solubility changes on air‐sea CO2 flux across the North Pacific basin (35°N–50°N, 142°E–125°W) throughout the full annual cycle by constructing mixed layer budgets for dissolved inorganic carbon (DIC) and pCO2, determined on 15 container ship transects between Hong Kong and Long Beach, CA, from 2008 to 2012. Annual air‐sea CO2 flux is greatest in the western North Pacific and decreases eastward across the basin (2.7 ± 0.9 mol C m−2 yr−1 west of 170°E, as compared to 2.1 ± 0.3 mol C m−2 yr−1 east of 160°W). East of 160°W, DIC removal by annual net community production (NCP) more than fully offsets the DIC increase due to air‐sea CO2 flux. However, in the region west of 170°E influenced by deep winter mixing, annual NCP only offsets ~20% of the DIC increase due to air‐sea CO2 flux, requiring significant DIC removal by geostrophic advection. Temperature‐driven solubility changes have no net influence on pCO2 and account for <25% of annual CO2 uptake. The seasonal timing of NCP strongly affects its influence on air‐sea CO2 flux. Biological carbon export from the mixed layer has a stronger influence on pCO2 in summer when mixed layers are shallow, but changes in pCO2 have a stronger influence on air‐sea CO2 flux in winter when high wind speeds drive more vigorous gas exchange. Thus, it is necessary to determine the seasonal timing as well as the annual magnitude of NCP to determine its influence on ocean carbon uptake.

OBSERVATIONAL IMPLICATIONS OF GAMMA-RAY BURST AFTERGLOW JET SIMULATIONS AND NUMERICAL LIGHT CURVE CALCULATIONS

We discuss jet dynamics for narrow and wide gamma-ray burst (GRB) afterglow jets and the observational implications of numerical simulations of relativistic jets in two dimensions. We confirm earlier numerical results that sideways expansion of relativistic jets during the bulk of the afterglow emission phase is logarithmic in time and find that this also applies to narrow jets with half opening angle of 0.05 rad. As a result, afterglow jets remain highly nonspherical until after they have become nonrelativistic. Although sideways expansion steepens the afterglow light curve after the jet break, the jet edges becoming visible dominates the jet break, which means that the jet break is sensitive to the observer angle even for narrow jets. Failure to take the observer angle into account can lead to an overestimation of the jet energy by up to a factor of four. This weakens the challenge posed to the magneter energy limit by extreme events such as GRB090926A. Late-time radio calorimetry based on a spherical nonrelativistic outflow model remains relevant when the observer is approximately on-axis and where differences of a few in flux level between the model and the simulation are acceptable. However, this does not imply sphericity of the outflow and therefore does not translate to high observer angles relevant to orphan afterglows. For more accurate calorimetry and in order to model significant late-time features such as the rise of the counterjet, detailed jet simulations remain indispensable.

Macroscopic Klein tunneling in spin-orbit-coupled Bose-Einstein condensates

We propose an experimental scheme to detect macroscopic Klein tunneling with spin-orbit coupled Bose-Einstein condensates (BECs). We show that a nonlinear Dirac equation with tunable parameters can be realized with such BECs. %in a simple configuration to generate the artificial spin-orbit coupling. Through numerical calculations, we demonstrate that macroscopic Klein tunneling can be clearly detected under realistic conditions. Macroscopic quantum coherence in such relativistic tunneling is clarified and a BEC with a negative energy is shown to be able to transmit transparently through a wide Gaussian potential barrier.
Singular spectrum analysis and envelope detection: methods of enhancing the utility of ground-penetrating radar data

Abstract We present a novel method of improving signal-to-noise ratio in radargrams. The method uses singular spectrum analysis (SSA) to separate each individual radar trace into orthogonal components. The components that explain most of the original trace variance contain mainly physically meaningful signal, while the components with little variance tend to be noise. Adding the largest-magnitude components together until the sum of components accounts for the variance above the noise level (typically 60–80%) of the original trace variance results in a much cleaner radargram with more easily seen internal features than in traditionally filtered data. The radargrams can be further enhanced by envelope-detecting the SSA-filtered data, as this measure of instantaneous energy minimizes the deleterious effects of innumerable phase changes at dielectric boundaries. Subsequent incoherent stacking results in far more structured radargrams than are achieved with traditionally processed radar data and amplitude stacking.
Influence of O Polysaccharides on Outer Membrane Vesicle Formation and Biofilm Development in Pseudomonas aeruginosa PAO1

INFLUENCE OF O POLYSACCHARIDES ON OUTER MEMBRANE VESICLE FORMATION AND BIOFILM DEVELOPMENT IN PSEUDOMONAS AERUGINOSA PAO1 Kathleen Murphy Advisor: University of Guelph, 2014 Dr. Cezar M. Khursigara Certain environmental conditions can alter the expression of the lipopolysaccharide (LPS) O polysaccharide on the surface of Pseudomonas aeruginosa cells. Changes in O polysaccharide expression influence cell surface characteristics. This study investigated the effect of directly altering O polysaccharide expression on outer membrane vesicle (OMV) production and composition, as well as biofilm formation. P. aeruginosa PAO1 produces two structurally distinct forms of O polysaccharide, the common polysaccharide antigen (CPA) and the O-specific antigen (OSA). Chromosomal knockout mutants of PAO1 that are defective in producing either OSA (∆wbpM) or CPA (∆rmd), or both (∆wbpL) were compared to wildtype cells. It was demonstrated that changes in O polysaccharide expression do not significantly influence OMV biogenesis, but do affect the size and protein sorting of OMVs. In addition, O polysaccharide expression was determined to influence biofilm development, and results from this study highlight the importance of CPA in this process.

Remote sensing and Gis applications for monitoring multi-temporal changes of natural resources in Bursa-Turkey.

The main objective was to investigate multi-temporal changes of the natural resources using remote sensing and geographic information system techniques. Landsat5 TM full frame images of 16 June 1984 and 06 August 1998 were used in this study. For this aim, three sub-scenes covering the Bursa city built-up area, Uluabat Lake and Mount Uludag and its surroundings were extracted from the images. Geometric correction and image enhancement were made for the comparison time series remote sensing data, exact image-on-map overlay and better visual interpretation. Boundary of the Bursa City built-up area and Uluabat Lake was produced from visually interpreted image using both screen and tablet digitizing. Biomass changes of the Mount Uludag and its surroundings were gathered from normalized vegetation index classification. The results revealed that the Bursa City built up areas have been expanded at a rate of 142.5 % from 5089 hectares (in 1984) to 12343 hectares (in 1998). The expansions in the built-up areas have been mainly occurred in valuable agricultural lands. In addition, the coverage area of the Uluabat Lake decreased at a rate of 12 % from 133.1 km( in 1984) to 116.8 (in 1998) km due to sediments transported by the surface water of surrounding irrigated agricultural lands, tributary streams and mainly Mustafakemalpasa River. Moreover, we found that 26292 ha mainly forest and floral areas have been degraded in fourteen years period. Key Word: Natural resources, temporal changes, monitoring, remote sensing, GIS.
Optimal Hedging Levels and Hedging Effectiveness in Cattle Feeding

Optimal hedging level, minimum-risk hedging level, and hedging effectiveness are defined in a manner consistent with portfolio theory and used to analyze hedging potential in cattle feeding. Estimated upper limits on optimal hedging levels ranged from 0.56 to 0.88 unit of short futures per unit of four types of slaughter cattle produced at five locations. When futures trading costs are taken into account, optimal hedging levels are depressed below these limits, depending upon the resource availabilities and profit expectations of individual firms. Location, grade, and sex of the cattle fed have small effects on optimal hedging levels and hedging effectiveness.
Automated Large Program Repair based on Big Code

The task of automatic program repair is to automatically localize and generate the correct patches for the bugs. A prominent approach is to produce a space of candidate patches, then find and validate candidates on test case sets. However, searching for the correct candidates is really challenging, since the search space is dominated by incorrect patches and its size is huge. This paper presents several methods to improve the automated program repair system Prophet, called Prophet+. Our approach contributes three improvements over Prophet: 1) extract twelve relations of statements and blocks for Bi-gram model using Big code, 2) prune the search space, 3) develop an algorithm to re-rank candidate patches in the search space. The experimental results show that our proposed system enhances the performance of Prophet, recognized as the state-of-the-art system, significantly. Specifically, for the top 1, our system generates the correct patches for 17 over 69 bugs while the number achieved by Prophet is 15.

Surface sizing with starch solutions at solids contents up to 18

La presente etude a porte sur le collage en surface du papier fin non couche, a l'aide d'une presse encolleuse doseuse a des teneurs en solides d'amidon considerablement plus elevees que d'ordinaire. Une vaste gamme de mesures rheologiques des teneurs en solides et en amidon etudiees est aussi presentee, ainsi qu'un ensemble de courbes de pellicules humides pour differents parametres des proprietes de l'amidon. Les resultats de l'etude indiquent qu'une grande variete de poids moleculaires de l'amidon peuvent etre utilises a des teneurs accrues en solides d'amidon. L'augmentation de la teneur en solides d'amidon n'est donc plus limitee aux amidons tres degrades. L'augmentation de la teneur en solides dans la solution d'amidon reduit les besoins d'energie pour l'evaporation, et la reduction du mouillage de la feuille de papier lors de l'encollage reduit le nombre de cassures de la feuille. L'emploi de solutions d'amidon a haute teneur en solides permet aussi d'utiliser le meme type de traitement de surface (par ex., le meme type de sechage et de garniture de rouleaux) tant pour le collage que pour le couchage.
Accounting for Disability Insurance in the Dynamic Relationship Between Disability Onset and Earnings

The onset of a work-limiting disability coincides with an immediate decline in earnings with little recovery. This study examines whether this relationship is attributable to the labor disincentives of disability insurance. The data come from the Survey of Income and Program Participation linked to administrative data from the Social Security Administration. The analysis suggests that disability insurance accounts for little of the initial drop in earnings at the time of disability onset, but its effect may increase as time since disability onset elapses. The results highlight the advantages of immediate, though temporary disability benefits.
The effects of carotid baroreceptor stimulation on blood pressure variability in young male athletes and non-athletes

The purpose of this study was to investigate the effects of carotid baroreceptor (BR) stimulation on blood pressure changes in young male volleyball players and non-athletes. Twenty five young male volleyball players and twenty-five young male non-athletes were recruited for voluntary participation in the present study. A neck suction device (Ekberg,s model) was used for stimulation of carotid baroreceptor. In this study the duration of stimulation was 70 s, and the negative pressure used was -30 mm Hg. Blood pressures were recorded before, during and after ending of stimulation of carotid baroreceptors in sitting position. Indirect pressure assessment was utilized for data acquisition. According to the results of this study, systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse blood pressure (PBP) significantly decreased compared to baseline levels in two groups (P<0.001). This research showed that the maximum reduction in SBP and PBP occurred in the 25th second, while for DBP the maximum reduction time was seen in the 5th second during stimulation in two groups. Also, maximum reduction in mean arterial blood pressure (MABP) in the group of athlete occurred in the 5th second, while in the group of non-athlete, it occurred in the 25th second . Our data showed a more reduction in SBP as compared with DBP, which was more evident in control group, although was not statistically significant. It is concluded that in athletes carotid baroreflex becomes more efficient due to long term physiological adaptations of exercise. Key words: Blood pressure, carotid baroreceptor, male athletes.
