RPIfield: A New Dataset for Temporally Evaluating Person Re-identification

The operational aspects of real-world human re-identification are typically oversimplified in academic research. Specifically, re-id algorithms are evaluated by matching probe images to candidates from a fixed gallery collected at the end of a video, ignoring the arrival time of each candidate. However, in real-world applications like crime prevention, a re-id system would likely operate in real time, and might be in continuous operation for several days. It would be natural to provide the user of such a system with instantaneous ranked lists from the current gallery candidates rather than waiting for a collective list after processing the whole video sequence. Re-id algorithms thus need to be evaluated based on their temporal performance on a dynamic gallery populated by an increasing number of candidates (some of whom may return several times over a long duration). This aspect of the problem is difficult to study with current benchmarking re-id datasets since they lack time-stamp information. In this paper, we introduce a new multi-shot re-id dataset, called RPIfield, which provides explicit time-stamp information for each candidate. The RPIfield dataset is comprised of 12 outdoor camera videos, with 112 known actors walking along pre-specified paths among about 4000 distractors. Each actor in RPIfield has multiple reappearances in one or more camera views, which allows the study of re-id algorithms in a more general context, especially with respect to temporal aspects.
Effect of dietary supplemental black cumin seeds on antioxidant activity in broilers

Lipid peroxidation is an autocatalytic mechanism leading to oxidative destruction of cellular membranes (8). Their destruction can lead to cell death and also to the production of toxic and reactive aldehyde metabolites, known as free radicals. Among these free radicals, malondialdehyde (MDA) is the most important (32). MDA is the main final product of lipid peroxidation and has been often used for determining oxidation damage (34) which is indicated by high levels of MDA. Black cumin (Nigella sativa) is widely grown in different parts of the world and it has been used to promote health (especially in the Middle East and Southeast Asia) as a digestive and appetite stimulant (16, 17), analgesic (22), anthelmintic (9) and antimicrobial (13), antidiabetic (4), anticancer (35), anti-inflammatory (3), spasmolytic and bronchodilator (15), hepatoprotective (25), renal protective (23) and antioxidant properties (6, 7, 24). The seeds of black cumin contain a volatile oil (0.5-1.6%), a fixed oil (35.6-41.6%), proteins (22.7%) and exogenic amino acids (2). The active constituents of the seeds include a volatile oil consisting of carvone, an unsaturated ketone, terpene or d-limonene also called carvene, ·­pinene and p-cymene (20). Pharmacologically active constituents of volatile oil are thymoquinone, dithymoquinone, thymohydroquinone and thymol (14). Black cumin seed oil and its main active constituent, thymoquinone, are reported to inhibit peroxidation in mice (19), rats (24) rabbits (28). Studies on the antioxidant status of black cumin in poultry have been very limited. The aim of the present study was to investigate the antioxidative effects of black cumin seeds in broilers. For this purpose, different amounts of black cumin seed were used to supplement broiler diets and MDA and vitamin E levels in serum, breast muscles, and liver and heart muscles were determined.
MAX CHART: COMBINING X-BAR CHART AND S CHART

Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread for variables data. When compared with the combination of X-bar chart and Sc hart, the proposed chart is shown to be just as ef fective. An example is given to show how to use this new chart.
Stochastic differential utility

A stochastic differential formulation of recursive utility is given sufficient conditions for existence, uniqueness, time consistency, monotonicity, continuity, risk aversion, concavity, and other properties. In the setting of Brownian information, recursive and intertemporal expected utility functions are observationally distinguishable. However, one cannot distinguish between a number of non-expected-utility theories of one-shot choice under uncertainty after they are suitably integrated into an intertemporal framework. In a "smooth" Markov setting, the stochastic differential utility model produces a generalization of the Hamilton-Bellman-Jacobi characterization of optimality. A companion paper explores the implications for asset prices. Copyright 1992 by The Econometric Society.
The new Milky Way satellites: alignment with the VPOS and predictions for proper motions and velocity dispersions

The evidence that stellar systems surrounding the Milky Way (MW) are distributed in a Vast Polar Structure (VPOS) may be observationally biased by satellites detected in surveys of the northern sky. The recent discoveries of more than a dozen new systems in the southern hemisphere thus constitute a critical test of the VPOS phenomenon. We report that the new objects are located close to the original VPOS, with half of the sample having offsets less than 20 kpc. The positions of the new satellite galaxy candidates are so well aligned that the orientation of the revised best-fitting VPOS structure is preserved to within 9 degrees and the VPOS flattening is almost unchanged (31 kpc height). Interestingly, the shortest distance of the VPOS plane from the MW center is now only 2.5 kpc, indicating that the new discoveries balance out the VPOS at the Galactic center. The vast majority of the MW satellites are thus consistent with sharing a similar orbital plane as the Magellanic Clouds, confirming a hypothesis proposed by Kunkel & Demers and Lynden-Bell almost 40 years ago. We predict the absolute proper motions of the new objects assuming they orbit within the VPOS. Independent of the VPOS results we also predict the velocity dispersions of the new systems under three distinct assumptions: that they (i) are dark-matter-free star clusters obeying Newtonian dynamics, (ii) are dwarf satellites lying on empirical scaling relations of galaxies in dark matter halos, and (iii) obey MOND.
Can Stellar Dynamics Explain the Metallicity Distributions of Presolar Grains?

The majority of presolar circumstellar SiC and Al2O3 grains found in meteorites are inferred to have originated in asymptotic giant branch (AGB) stars that were more metal-rich than the Sun despite being much older than the Sun. We test the suggestion of Clayton that this reflects the overwhelming diffusion of AGB stars from the more metal-rich inner Galaxy to the protosolar cloud. Weighting the orbital diffusion model of Wielen, Fuchs, & Dettbarn to take into account the higher density of AGB stars and molecular clouds in the inner Galaxy, we find that most parent stars of presolar grains should have diffused to the presolar cloud from their birthplaces at smaller Galactocentric radii. However, the majority of these stars are expected to have had subsolar metallicities, in conflict with the grain data. The self-consistency of the diffusion model is discussed in the context of stellar abundance data in the solar neighborhood. The disagreement between the model predictions and the observations might indicate that the inferred metallicities of presolar grain parent stars are wrong, that the adopted diffusion parameters are incorrect, and/or that stellar orbital diffusion is not the correct explanation for the grain data.
Does Tax Enforcement Counteract the Negative Effects of Terrorism? A Case Study of the Basque Country

This paper analyses the impact of terrorism on tax enforcement policies by focusing on the case of the Basque Country. The presence of externalities in tax administration attributable to the costs of terrorism is investigated by undertaking a theoretical analysis. The findings of this are tested using Spanish data extracted from repeated surveys and other sources. By employing ordered response models, evidence is found of the negative impact of terrorism on tax enforcement as it is perceived by residents in the Basque Country and Navarre. In particular, this impact is found to be stronger for entrepreneurs and liberal professionals. No significant impact is found for individuals resident in the rest of Spain.
Comparison of the effect of semi-rigid ankle bracing on performance among injured v. non-injured adolescent female hockey players

Objective. To determine the comparative proprioceptive performance of injured v. non-injured adolescent female hockey players wearing an ankle brace. Methods. Data were collected from 100 high school players who belonged to the Highway Secondary School Hockey League, KwaZulu-Natal, via voluntary parental informed consent and player assent. Players completed an injury questionnaire probing the prevalence and nature of hockey injuries (March - August 2013). Subsequently, players completed a Biodex proprioceptive test with and without an ankle brace. Probability was set at p ≤0.05. Results . Twenty-two players sustained ankle injuries within the 6-month study period ( p 0.05). However, bracing improved the ankle stability of the non-injured group (RAPI 2.2 (0.8); RMLI 1.5 (0.5); LAPI 2.4 (0.9); RMLI 1.5 (0.5)) compared with their performance without a brace (RAPI 2.5 (1.0); RMLI 1.8 (0.8); LAPI 2.8 (1.1); LMLI 1.8 (0.6)) ( p< 0.05). Conclusion. Ankle bracing did not enhance the stability of injured ankles. However, ankle bracing has an ergogenic effect that enhances the stability of healthy ankles.
How the non-ideality of real gases affects results of the ozone Standard Reference Photometer (SRP)

The equations that describe the operation of the ozone Standard Reference Photometer (SRP) assume that dry air mixed with trace amounts of ozone is an ideal gas. The following report examines this assumption in considerable detail and concludes that it is indeed justified within typical operating conditions of the SRP. This report also answers the related question of whether there is a difference between ozone mole fractions, typically reported as nmol/mol, and the corresponding volume fractions, typically reported as ppbv.
Removal of Cu(II), Pb(II) and Zn(II) Ions from Aqueous Solutions Using Selected Agricultural Wastes: Adsorption and Characterisation Studies

The feasibility of durian tree sawdust (DTS), coconut coir (CC) and oil palm empty fruit bunch (EFB) as low-cost biosorbents for the removal of Cu(II), Pb(II) and Zn(II) ions from aqueous solutions was investigated. The effects of solution pH and initial metal concentration on adsorption capacity were examined in batch experiments. The affinity and the adsorption capacity of DTS, CC and EFB were evaluated. The adsorption behaviour of Cu(II), Pb(II) and Zn(II) ions onto DTS, CC and EFB was described using Freundlich and Langmuir isotherm models. The separation factor (RL) analysis suggests that the removal of metal ions onto three agricultural wastes studied was favourable. The maximum adsorption capacities (Q) estimated from the Langmuir isotherm model for Cu(II), Pb(II) and Zn(II) were 18.42, 20.37 and 22.78 mg/g for DTS, 18.38, 37.04 and 24.39 mg/g for CC, and 26.95, 37.59 and 21.19 mg/g for EFB, respectively. The characterisation studies were carried out using Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectrometer (EDX) and Fourier Transform Infrared Spectrometer (FTIR). The surface morphology of the biosorbents changed significantly following interaction with metal ions. The primary adsorption mechanism was complexation between metal ions and binding sites of biosorbents. Both hydroxyl and amine groups are the main binding sites in DTS, CC and EFB.
Evaluation of MIMO Non- Stationarity

The transmission performance of MIMO systems can be highly improved under stationary channel conditions where the channel statistics are constant. Unfortunately, mobile radio channels are not stationary all the time. Instead, they are stationary for finite time durations, so-called the stationarity regions. If these stationarity regions are relatively large, then the channel statistics can be utilized during each stationarity region to enhance the transmission performance. Therefore, it is necessary to examine the stationarity of mobile channels and characterize the stationarity regions. This thesis investigates the non-stationarity of measured MIMO channels and proposes some stationarity metrics to measure it. These metrics are: the CMD proposed by [1 ], NCMD and DES. Each one of the metrics is relevant to different types of transmission schemes and scenarios. The CMD may not be accurate for some transmission scenarios; therefore, the NCMD, which is a normalized version of CMD, is proposed. Theoretically, the NCMD can be at most 100% higher than the CMD for a 4x4 MIMO system. For beamforming scenario, the DES metric can be used to describe the non-stationarity of few eigenvectors taken from the channel variance. Under the measured MIMO channels, it was found that the CMD overestimates the stationarity regions compared to the NCMD and DES metrics particularly under the NLOS routes.
Challenges Facing Principals in the First Year at Their Schools.

The aim of this study is to identify key challenges of practice that principals face. In line with this purpose, the researcher has employed a qualitative research methodology, interviewing principals working in Amasya district, over and above doing document analysis to collect detailed information concerning leadership and administration practice. After analyzing the collected data, the researcher has found that most participant principals have complained about their profession; therefore, they are more likely to leave their occupation. Furthermore, the principals have reported that they have faced the following challenges in schools: 1) violence, 2) families' negative attitudes towards school, 3) immigrant students/families from Syria and Iraq, 4) teacher unions (syndicalism), 5) teachers' attitudes and behaviors to principals, and 6) increasing of undesired behaviors in classroom/school. In the light of the above findings, the researcher has concluded that working as a principal in a school is more difficult than before. However, for the future of Turkey, Turkish policymakers, researchers, and educators should work together to minimize the negative impact of challenges and keep principals in the Turkish Education System.
Use of Malaria Rapid Diagnostic Tests among Medical Doctors in a Tertiary Hospital, South East Nigeria

Malaria is a major health problem in Nigeria that has as high as 25% of all global cases, and 30% of deaths attributable to malaria. In 2010, World Health Organization (WHO) recommended universal confirmation of diagnosis of malaria through blood parasitological test, prior to initiation of treatment. In addition to Microscopy, Malaria Rapid diagnostic Tests (mRDTs) are blood tests for malaria. Early diagnosis of malaria ensures that the correct treatment is commenced in good time, and this subsequently improves the prognosis. The objective of this study is to assess the use of mRDTs among medical doctors working in a tertiary hospital, Southeast Nigeria. This study was conducted in Enugu State Teaching hospital, Southeast Nigeria. The study was of cross-sectional design, and conducted in October 2016 among medical doctors working in the General Outpatient, Internal Medicine, and Paediatrics departments of the Teaching hospital. Statistical Package for Social Sciences (SPSS) version 20.0 was used for data analysis. A total of 86 medical doctors, out of the eligible 91 in the three departments participated in the study, and were distributed as follows; 24 (27.9%) in the General Outpatient, 30 (34.9%) in the Internal Medicine, and 32 (37.2%) in the Paediatrics departments. More medical doctors in the Paediatrics department (31.3%) used mRDTs in making diagnosis of malaria, followed by Internal medicine (13.3%), then General Outpatient Department (8.3%). Malaria rapid diagnostic tests are cost-effective, and useful tools in malaria control and elimination programmes. If tangible progress on the implementation of the WHO guidelines on confirming diagnosis of malaria before treatment; and the T3: Test, Treat, Track initiative is to be made; then the government and the Management of hospitals ought to take more determined efforts aimed at educating and informing health workers, especially medical doctors on the benefits of mRDTs.
Phosphorus utilisation and growth performance of broiler chicken fed diets containing graded levels of supplementary myo-inositol with and without exogenous phytase

A total of 80 male Ross 308 broiler chickens were used in this study to quantify the response and interrelationship of bird growth performance, dietary nitrogen corrected apparent metabolisable energy (AMEn), and nutrient digestibility as a result of feeding graded levels of supplementary myo-inositol (MYO) with and without exogenous phytase (PHY). Supplementation of diet that was formulated to be insufficient in available Phosphorus (P) with graded levels of MYO improved daily weigh gain (WG) and AMEn intake (P<0.05; quadratic) and linearly reduced (P<0.05) the concentration and the secretion of sialic acid (SA) in excreta. Supplementation with PHY improved (P<0.05) dietary dry matter (DMD) and nitrogen (ND) digestibility coefficients. Dietary phosphorus digestibility (PD) increased with PHY addition as expected but the effect was much more pronounced in the low MYO group compared with high MYO diets as described by the interaction (P<0.05). The interaction showed that increasing MYO content had no effect in the absence of PHY but it depressed P digestibility in the diets containing PHY. It can be concluded that dietary MYO improves bird growth and possibly intestinal health of broiler chickens. Dietary supplementation with either MYO or PHY may improve growth of chickens although these effects may not always be additive.
Laboratory Hydrogen-Beta Emission Spectroscopy for Analysis of Astrophysical White Dwarf Spectra

This work communicates a review on Balmer series hydrogen beta line measurements and applications for analysis of white dwarf stars. Laser-induced plasma investigations explore electron density and temperature ranges comparable to white dwarf star signatures such as Sirius B, the companion to the brightest star observable from the earth. Spectral line shape characteristics of the hydrogen beta line include width, peak separation, and central dip-shift, thereby providing three indicators for electron density measurements. The hydrogen alpha line shows two primary line-profile parameters for electron density determination, namely, width and shift. Both Boltzmann plot and line-to-continuum ratios yield temperature. The line-shifts recorded with temporally- and spatially- resolved optical emission spectroscopy of hydrogen plasma in laboratory settings can be larger than gravitational redshifts that occur in absorption spectra from radiating white dwarfs. Published astrophysical spectra display significantly diminished Stark or pressure broadening contributions to red-shifted atomic lines. Gravitational redshifts allow one to assess the ratio of mass and radius of these stars, and subsequently, the mass from cooling models.
Green engineering of titanium dioxide nanoparticles using Ageratina altissima (L.) King & H.E. Robines. medicinal plant aqueous leaf extracts for enhanced photocatalytic activity

In the present study, the titanium dioxide nanoparticles (TiO2NPs) were synthesized by using Ageratina alttissima (L.) King & H.E. Robines. (White Snakeroot) medicinal plant aqueous leaf extracts by microwave irradiation method. The green synthesized TiO2NPs showed the best photocatalyst due to its long thermodynamic stability and strong oxidizing power. The synthesized titanium dioxide nanoparticles were characterized by using UV-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), and Energy dispersive X-Ray analysis (EDX). FTIR was performed to identify the possible functional biomolecules capped on the surface of TiO2NPs during interaction. In XRD result, the dominant peak of TiO2 2 value is matched with the crystallographic rutile structure which indicates the polycrystalline nature. FESEM analysis revealed the spherical shape and size of the synthesized TiO2NPs. In this study, the degradation process of textile dyes was carried by photocatalytic activity using synthesized TiO2NPs. The photocatalytic activity of the synthesized TiO2NPs showed enhanced percentage of decoloring of textile dyes such as methylene blue (86.79 %), alizarin red (76.32 %), crystal violet (77.59 %), and methyl orange (69.06 %). The findings of this study clearly indicated that the synthesized TiO2 nanoparticles A. alttissima be used as an alternative and eco-friendly compound to remove and degrade the pollutants released from textile and dyeing industries.
The impact of process temperature on mammalian cell lines and the implications for the production of recombinant proteins in CHO cells

The use of a temperature-shift to subphysiological temperatures (<37°C) during the culturing of mammalian cell lines engineered to produce a recombinant protein is widely utilized. The effect of such a temperature shift on both the cellular responses and recombinant protein yield is not uniform and is both cell- and product-specific. Despite this, the understanding of the cellular responses to mild subphysiological temperature (27–35°C) culturing has developed markedly over the last decade and, as such, opportunities exist to harness this knowledge to further improve product yields and quality at subphysiological temperatures. In this review we describe the mammalian cell response to mild subphysiological temperature, the effects on recombinant protein production under such conditions, those mechanisms that appear to underpin increases in productivity at such temperatures, and potential future innovations and directions that may further enhance the use of such conditions during bioprocessing of recombinan.
