A DFT Calculation: Toxicity of Water Soluble Arsenicals

We have used the density functional theory to make a predictive toxicity model of water soluble arsenicals. The structures are optimized for the minimum energy of the Schrodinger equation. From this optimized structure, we obtain the bond distance and angles of the stable structures. We have calculated vibrational frequencies, Ionization potential, atomic charges, electrophilicity and electron affinity of those arsenicals. The calculated vibrational frequencies and other physical properties are compared with those found from the different experiment. The mode of vibrational frequencies, electrophilicity and atomic charges (Mulliken) calculated for MMA(III) , DMA(III) ,arsenic acid, arsenous acid, MMA(V) and DMA(V) that follows acute toxicity of those arsenicals in laboratory animals. Raman micro-spectroscopy might also be showed its potential applications in the toxicology screening of chemicals and new biomaterials, with a range of cell types. Applying the model one could predict toxicity level of unknown water soluble arsenicals in future.

Performance of Gilts and Boars with High and Low EBV ’ s for Litter Size , Average Daily Gain and Backfat

“ What about the genetic improvement of litter size ” was the title of a paper by Skervold (1979) who discussed possible reasons for the lack of genetic improvement in litter size and showed strategies for selection methods to improve litter size. However, no significant genetic trends in litter size have been achieved in various countries as shown in a summary by de Vries and Kanis (1994). Skervold (1979) suggested that low heritability and/or low selection differential may be the reason for this lack of improvement, and suggested use of information on paternal halfsisters and the maternal granddam in addition to the dam’s performance. Best Linear Unbiassed Prediction (BLUP) procedures make use of information from all relatives. This should make better selection for litter size possible. Longterm performance recording, as it is available on some farms today, allows the comparison of EBV’s for litter size in gilts with their phenotypic performance in their later life. This will give an indication of the possibility for improving litter size using BLUP technology.
Discriminatory Taxes are Unpopular Even When They are Efficient and Distributionally Fair

We explore the political acceptance of taxation in commodity markets. Participants in our experiment earn incomes by trading and must collectively choose one of two tax regimes to raise a given tax revenue. A "uniform tax" (UT) imposes the same tax rate on all markets and is fair in that it yields the same - but low - income to participants in all markets. The "discriminatory tax" (DT) imposes a higher burden on markets with inelastic demand and is therefore efficient but it is also unfair in that incomes are unequal across markets. We find that DT are unpopular, as predicted. Surprisingly, however, DT remain unpopular when they are both efficient and produce a fair (equal) distribution. We conclude that non-discrimination (equal treatment) is a salient fairness principle in taxation that shapes voting on commodity taxes above and beyond concerns for efficiency and equal distribution.

Aqueous extract of Inocutis levis improves insulin resistance and glucose tolerance in high sucrose-fed Wistar rats

Introduction: Inocutis levis is a polypore fungus belonging to Hymenochaetales of basidiomycetes. The specie is mainly distributed in Asia and grows on living angiosperm trees. This study investigates the effect of aqueous extract of I. levis on insulin resistance and glucose tolerance in high sucrose fed (HSF) rats.Methods: Male rats were given 30% sucrose solution for 12 weeks. The extract of I. levis at doses of 50 and 150 mg/kg body weight was intraperitoneally administered for 2 weeks in HSF rats. Blood glucose, serum insulin, insulin resistance index (HOMA-IR) and histological changes of pancreas were evaluated.Results: Sucrose solution significantly increased the insulin, glucose and HOMA-IR levels, compared to the control. At the dose of 50 mg/kg the extract decreased glucose and insulin, and improved insulin resistance relative to that of HSF rats which did not take the extract. Histological studies on pancreas tissue indicated no significant difference in the size of Langerhans islets of HSF rats and HSF rats treated with the extract at dose of 50 mg/kg compared to the control group. But, treatment with the dose of 150 mg/kg of I. levis increased islets diameter and number of cells in the islets of Langerhans in HSF group.Conclusion: Inocutis levis extract may have hypoglycemic effects, by regulating insulin secretion and improving glucose tolerance, and seems to be able to ameliorate pancreatic islets in HSF rats. Our findings indicate that I. levis can be considered as a potential treatment with medicinal properties to alleviate insulin resistance and to prevent risk of type 2 diabetes in a dose dependent manner.
WIFI/PDR indoor integrated positioning system in a multi-floor environment

Location-based services (LBS) are services offered through a mobile device that take into account a device’s geographical location. To provide position information for these services, location is a key process. The creation of systems for solving problems of positioning and navigation inside buildings is a very perspective, actual and complicated task, especially in a multi-floor environment. To improve the accuracy of indoor positioning for location-based services, we created an improved WiFi/PDR (Pedestrian Dead Reckoning) integrated positioning and navigation system where we are using Extended Kalman filter (EKF). The proposed algorithm first relies on MEMS in our mobile phone to estimate the velocity and heading angles of the target. Second, the velocity and heading angles, together with the results of WiFi fingerprinting-based positioning, are considered as the input of the EKF for the sake of conducting two-dimensional (2D) positioning. Third, the proposed algorithm calculates the altitude of the target by using the real-time recorded barometer and geographic data. Tests were conducted on two floors of the building to achieve three-dimensional (3D) positioning in multi-floor environment using proposed integrated WiFi/PDR positioning algorithm. The results of our experiments show that integrated navigation system using Extended Kalman filter can effectively eliminate the accumulated errors in the PDR positioning algorithm and can reduce the influence of the large-scale jump of the WiFi fingerprint positioning result brought by the RSSI disturbance on the positioning accuracy of the system. In a real multi-floor environment, the proposed algorithm of WiFi/PDR integrated system has a mean error of positioning accuracy is 1.6m, which is much less than the 10m of the WiFi alone positioning result, and the 2m of the PDR alone positioning result.
Error Tolerant Digital Watermarking System for the Application of Noisy RGB Images

As we witness that present age is information age also known as the digital age, or new media age which is based on internet, hence data transmission is online and happens in real time. With the help of modern digital technology and increasingly powerful image processing tools one can easily manipulate the digital data such as image, voice and videos without leaving obvious visual traces of data having been tampered, hence there is an urgent need to identify and protect the authenticity of the data. In the fields such as forensics, medical imaging, e-commerce, and industrial photography, authenticity and integrity of digital images is essential. Various methods and research issues involving the tampering detection and image authentication have been discussed and Digital Watermarking provides a suitable approach towards addressing this problem. It is also evident that due to online transmission there is a possibility of having noise on input image as well; hence in this paper we present an error tolerant watermarking system which is ideal for the application of noisy RGB images. According to our proposed approach we follow the logic of resizing of the image and use of approximate Gaussian smooth filter. Also the applications and needs of digital watermarking have been discussed here.
Sentencing Reform Lessons: From the Sentencing Reform Act of 1984 to the Feeney Amendment

For more than two decades, Congress has been on a mission to obtain uniformity in the federal sentencing system. What began with the Sentencing Reform Act of 1984 ("SRA"), and was soon followed by the Sentencing Guidelines, has been continually criticized by both the judiciary and the legislature. ' In the spring of 2003, in what caught many interested parties off guard, Congress abruptly responded to the perceived inadequacies of the federal sentencing system by enacting the Feeney Amendment to the PROTECT Act ("The Prosecutorial Remedies and Tools Against the Exploitation of Children Today Act of 2003"), signed into law by President Bush on April 30, 2003.2 The Act implemented sweeping reforms focused on eliminating trial judges' discretion to deviate from congressionally mandated sentences.3
Multi-Platform Strategy: Tencent Case Study

Two-sides platform is hot topic in the new networked economy, and it is applied in many areas. Network effect is always appearing with two-sides platform. This paper use case study method to figure out how the platforms and services of Tencentcontribute to each other and what results these interactions bring under the effect of economies of scope and economies of density theory. This thesis shows that 14 platforms of Tencentbelong to four types and six secondary classifications of two-sides platform. The complex interactions between them result the decrease of costs and increase of users and traffics.
A CHANGE GUIDE METHOD BASED ON DEVELOPERS' INTERACTION AND PAST RECOMMENDATION

In this paper, we propose a change guide method based on the past developers’ activity that consists of read and write access records of artifacts. In our proposed method, we calculate candidates of next change recommendation considering the history of its recommendations. We define “cumulative likelihood” to enable the method to recommend the appropriate candidates when a change propagates more than one code elements. A case study using interaction history logs from 15 participants showed the improvement of the accuracy of the method-level change recommendation.
Spatially resolved physical conditions of molecular gas and potential star formation tracers in M 83, revealed by the Herschel SPIRE FTS

We investigate the physical properties of the molecular and ionized gas, and their relationship to the star formation and dust properties in M 83, based on submillimeter imaging spectroscopy from within the central 3.5′ (~4 kpc in diameter) around the starburst nucleus. The observations use the Fourier Transform Spectrometer (FTS) of the Spectral and Photometric Imaging REceiver (SPIRE) onboard the Herschel Space Observatory. The newly observed spectral lines include [CI] 370 μm, [CI] 609 μm, [NII] 205 μm, and CO transitions from J = 4−3 to J = 13−12. Combined with previously observed J = 1−0 to J = 3−2 transitions, the CO spectral line energy distributions are translated to spatially resolved physical parameters, column density of CO, N(CO), and molecular gas thermal pressure, Pth, with a non-local thermal equilibrium (non-LTE) radiative transfer model, RADEX. Our results show that there is a relationship between the spatially resolved intensities of [NII] 205 μm and the surface density of the star formation rate (SFR), ΣSFR. This relation, when compared to integrated properties of ultra-luminous infrared galaxies (ULIRGs), exhibits a different slope, because the [NII] 205 μm distribution is more extended than the SFR. The spatially resolved [CI] 370 μm, on the other hand, shows a generally linear relationship with ΣSFR and can potentially be a good SFR tracer. Compared with the dust properties derived from broad-band images, we find a positive trend between the emissivity of CO in the J = 1−0 transition with the average intensity of interstellar radiation field (ISRF), ⟨ U ⟩. This trend implies a decrease in the CO-to-H2 conversion factor, XCO, when ⟨ U ⟩ increases. We estimate the gas-to-dust mass ratios to be 77 ± 33 within the central 2 kpc and 93 ± 19 within the central 4 kpc of M 83, which implies a Galactic dust-to-metal mass ratio within the observed region of M 83. The estimated gas-depletion time for the M 83 nucleus is 1.13 ± 0.6 Gyr, which is shorter than the values for nearby spiral galaxies found in the literature (~2.35 Gyr), most likely due to the young nuclear starbursts. A linear relationship between Pth and the radiation pressure generated by ⟨ U ⟩, Prad, is found to be Pth ≈ 30 Prad, which signals that the ISRF alone is insufficient to sustain the observed CO transitions. The spatial distribution of Pth reveals a pressure gradient, which coincides with the observed propagationof starburst activities and the alignment of (possibly background) radio sources. We discover that the off-centered (from the optical nucleus) peak of the molecular gas volume density coincides well with a minimum in the relative aromatic feature strength, indicating a possible destruction of their carriers. We conclude that the observed CO transitions are most likely associated with mechanical heating processes that are directly or indirectly related to very recent nuclear starbursts.
Prevalence of Internet Addiction among Nursing Students and the Association with their Academic Performance and Mental Health

The objective was to investigate the prevalence of Internet Addiction (IA) among nursing students and its association with their mental health and academic performance, at king Saud Bin Abdul-Aziz University for Health Sciences, Jeddah. A descriptive correlation exploratory design was used with 147 females students selected conveniently. A self-administered Arabic version of Young (1995) IA scale and depression scale developed by Radloff (1977) were used to collect data. Almost 2 thirds of the participants (59.6%) were average on-line users compared with 38.4% and 2.1% experiencing both moderate, and sever IA, respectively. More than 2 thirds (64.6%) were experienced with depressive symptoms compared with only 35.4%, who were normal. A significant correlation was found between IA, time spent on the Internet, and depressive symptoms (r=0.335 and r=0.205), respectively. Therefore, conducting an in-service training program of Internet use and promoting a supportive environment of counseling will decrease the psychological morbidity of stress and depression among college students.
The Modelling and Seasonal Adjustment of Weekly Observations - (Now published in 'Journal of Business and Economic Statistics', 15 (1997), pp.354-368.)

A number of important economic time series are recorded on a particular day every week. Seasonal adjustment of such series is difficult because the number of weeks varies between 52 and 53 and the position of the recording day changes from year to year. In addtion certain festivals, most notably Easter, take place at different times according to the year. This paper presents a general solution to problems of this kind by setting up a structural time series model which allows the seasonal pattern to evolve over time and enables trend extraction and seasonal adjustment to be carried out by means of state space filtering and smoothing algorithms. The method is illustrated with a Bank of England series on the money supply.
Assessing Changes in Fisheries Using Fishers’ Knowledge to Generate Long Time Series of Catch Rates: a Case Study from the Red Sea

The data requirements for most quantitative fishery assessment models are extensive, and most of the fisheries in the world lack time series of the required biological and socioeconomic data. Many innovative approaches have been developed to improve data collection for fisheries. We explored the use of data from fishers' interviews to estimate time series of approximate "best" catch rates. A total of 472 standardized interviews were conducted with 423 fishers along the southern Red Sea coast recording the best catch recalled and the change in average catch rates throughout the fishing career of interviewees. The results showed a decline of best catch rates in all fisheries, ranging from 4% to 10% per year for more than 50 years. The estimated rates of decline of the typical catch were higher for fishers who started fishing in recent years, suggesting that the resource base is declining, in concordance with other indicators. It is suggested that analysis of approximate data, quickly acquired at low cost from fishers through interviews, can be used to supplement other data-recording systems or used independently to document the changes that have occurred in the resource base over a lifetime of fishing. The results can be used to guide the assessment and management of resources to conserve ecosystems and livelihoods.
XMM-Newton observations of the Galactic Centre Region - II. The soft-thermal emission

We have extended our earlier study (Heard & Warwick 2013, Paper I) of the X-ray emission emanating from the central 100 pc x 100 pc region of our Galaxy to an investigation of several features prominent in the soft X-ray (2-4.5 keV) band. We focus on three specific structures: a putative bipolar outflow from the vicinity of Sgr A*; a high surface brightness region located roughly 12 arcmin to the north-east of Sgr A*; and a lower surface-brightness extended loop feature seen to the south of Sgr A*. We show that all three structures are thermal in nature and have similar temperatures (kT ~ 1 keV). The inferred X-ray luminosities lie in the range (2 - 10) x 10^34 erg s^-1. In the case of the bipolar feature we suggest that the hot plasma is produced by the shock-heating of the winds from massive stars within the Central Cluster, possibly collimated by the Circumnuclear Disc. Alternatively the outflow may be driven by outbursts on Sgr A*, which follow tidal disruption events occurring at a rate of roughly 1 every 4000 yr. The north-east enhancement is centred on a candidate PWN which has a relatively hard non-thermal X-ray spectrum. We suggest that the coincident soft-thermal emission traces the core of a new thermal-composite supernova remnant, designated as SNR G0.13-0.12. There is no clear evidence for an associated radio shell but such a feature may be masked by the bright emission of the nearby Radio Arc and other filamentary structures. SNR G0.13-0.12 is very likely interacting with the nearby molecular cloud, G0.11-0.11, and linked to the Fermi source, 2FGL J1746.4-2851c. Finally we explore a previous suggestion that the elliptically-shaped X-ray loop to the south of Sgr A*, of maximum extent ~45 pc, represents the shell of a superbubble located in the GC region. Although plausible, the interpretation of this feature in terms a coherent physical structure awaits confirmation.

In the study, a BIM has been converted and displayed in 2D on Google Maps, and information on various sensors have been represented on the web with geographic coordinates in real-time.
Presence : A Network of Reciprocal Relations

In this paper, I propose an alternative explication of presence based on the theoretical framework provided by theatrical presence. In my opinion, a unified and consistent discourse about presence has emerged since the earliest theorizations and explications of telepresence in the ‘80s. Scholars, scientists, engineers, psychologists, philosophers and virtual reality experts have defined remote and virtual presence according to a common denominator: the assumption that presence is the result of subjective sensory rich experience mainly given by immersion and unilateral activity (vision and action). On the contrary, according to the explication proposed in this paper, presence occurs when natural and/or technological conditions allow for reciprocal relationships. Finally, political and social issues related to presence and remote presence are taken into account. Keywords--Theatrical presence, presence, remote
Possible Quaternary growth of a hidden anticline at the front of the Jura fold-and-thrust belt: geomorphological constraints from the Forêt de Chaux area, France

This study presents new constraints for Plio-Quaternary (post-2.4 Ma to present-day) anticline growth along the frontal zone of the Jura fold-and-thrust belt, in the Foret de Chaux area, located 30 km SW of Besancon. The Foret de Chaux area consists of a N080°E-elongated depression bordered by the Doubs and Loue rivers to the north and south respectively, and filled with Sundgau-type Pliocene alluvial deposits. The upper surface of the Pliocene deposits between the Loue and Doubs rivers is marked by a N065°E-trending ridge crossing the depression in a median position. A differential uplift along this ridge, post-dating the deposition of the gravels (2.4 Ma), is suggested by several geomorphological observations such as the opposite river migration on each side of the ridge as well as variations of drainage geometry and incision intensity. Geological and geophysical subsurface data indicate that the ridge roughly coincides with the axis of an anticline hidden beneath the Pliocene deposits. The observed uplift is presumably related to a post-2.4 Ma anticline growth. The fact that the azimuth of the hidden anticline axis is parallel to the strike of deep-seated Late Paleozoic basement faults and not to the local strike of the thin-skinned Jura structures indicates that the inferred post-Pliocene deformation could possibly be an expression of a recent thick-skinned deformation of the basement of the northern Alpine foreland. The focal depth (15 km) of the February 24th, 2004, Besancon earthquake supports the hypothesis of a basement fault reactivation.
