description: Objective : Brucellosis is an infection transmissible from animals to humans. It is underestimated and neglected in Mali. The aim of this study was to determine the seroprevalence of brucellosis in small ruminants and to identify risk behaviours that may favour its transmission between animals and from animal to human.
Method: A study was conducted in Sikasso, Ségou regions and peripheral areas of Bamako district, Mali. Blood was collected from 860 small ruminants. The sera obtained were examined using the Rose Bengal and cELISA tests. Furthermore, 119 livestock owners underwent an interview using a questionnaire.
Results: The overall seroprevalence was 4.1%. At region level, this prevalence was 4.46% in peripheral areas of Bamako, 6.7% in Ségou and 2.1% in Sikasso. Regarding animal species, more sheep were found to be infected than goats 2.8% vs 1.7%, Risk behaviours such as promiscuity of animals (90.8%) mismanagement of abortion materials (48.7%) and consumption of unpasteurised raw milk and/or fermented milk products (33.6%) were identified as risky behaviours for humans. Also, loaning and mixing herds on pasture areas (63.9%) and exchanging reproductive males (30.3%) were identified as risky behaviours that favour transmission between animals.
Conclusion: These findings are importance for the development of a one-health brucellosis control policy in
Mali.

description: The applications of terahertz (THz) radiation for plant water status monitoring require systematic studies on interaction of THz wave and plants. Here, we present theoretical investigations on scattering behavior of THz waves reflected by and transmitting through a plant leaf under different water content. A theoretical model combining integral equation and radiative transfer theory is presented to fit the measured data. Good agreement confirms the availability of the model for water status evaluation when variation of leaf thickness and surface roughness is considered. We investigate the applicability of THz waves for water status monitoring in reflection and transmission geometries under different temperatures, salinities and polarizations.

description: We propose a systematic methodology for defining tournament solutions as extensions of maximality. The central concepts of this methodology are maximal qualified subsets and minimal stable sets. We thus obtain an infinite hierarchy of tournament solutions, which encompasses the top cycle, the uncovered set, the Banks set, the minimal covering set, the tournament equilibrium set, the Copeland set, and the bipartisan set. Moreover, the hierarchy includes a new tournament solution, the minimal extending set, which is conjectured to refine both the minimal covering set and the Banks set.

description: Several publications highlight the importance of the observations of bow shocks to learn more about the surrounding interstellar medium and radiation field. We revisit the most prominent dusty and gaseous bow shock source, X7, close to the supermassive black hole, Sgr~A*, using multiwavelength analysis. For the purpose of this study, we use SINFONI (H+K-band) and NACO ($L'$- and $M'$-band) data-sets between 2002 and 2018 with additional COMIC/ADONIS+RASOIR ($L'$-band) data of 1999. By analyzing the line maps of SINFONI, we identify a velocity of $\sim 200$ km/s from the tip to the tail. Furthermore, a combination of the multiwavelength data of NACO and SINFONI in the $H$-, $K$-, $L'$-, and $M'$-band results in a two-component black-body fit that implies that X7 is a dust-enshrouded stellar object. The observed ongoing elongation and orientation of X7 in the Br$γ$ line maps and the NACO $L'$-band continuum indicate a wind arising at the position of Sgr~A* or at the IRS16 complex. Observations after 2010 show that the dust and the gas shell seems to be decoupled in projection from its stellar source S50. The data also implies that the tail of X7 gets thermally heated up due to the presence of S50. The gas emission at the tip is excited because of the related forward scattering (Mie-scattering), which will continue to influence the shape of X7 in the near future. In addition, we find excited [FeIII] lines, which underline together with the recently analyzed dusty sources and the Br$γ$-bar the uniqueness of this source.

description: Missense mutations are changes in the DNA that result in a change in the amino acid sequence. Depending on their location within the protein they can have a negative impact on how the protein functions. This is especially important for proteins involved in the body’s response to infection and diseases. Macrophage migration inhibitory factor (MIF) is one such protein that functions to recruit white blood cells to sites of inflammation.
In this study we used computers to perform calculations that allowed us to predict and approximate how these changes might affect the function and behavior of the protein. The missense mutations were retrieved from a database of reported mutations in humans.
Our research identified 17 missense mutations that appear to destabilize the MIF protein. The results generated are useful in informing which positions within the protein might be important for function. Further, we believe the approaches used here will help in identifying mutations that can alter function and cause disease or potentially druggable regions of parasite proteins to facilitate drug discovery

description: A number of the massive clusters in the halo, bulge and disc of the Galaxy are not genuine globular clusters (GCs), but instead are different beasts altogether. They are the remnant nuclear star clusters (NSCs) of ancient galaxies since accreted by the Milky Way. While some clusters are readily identifiable as NSCs, and can be readily traced back to their host galaxy (e.g., M54 and the Sagittarius Dwarf galaxy) others have proven more elusive. Here we combine a number of independent constraints, focusing on their internal abundances and overall kinematics, to find NSCs accreted by the Galaxy and trace them to their accretion event. We find that the true NSCs accreted by the Galaxy are: M54 from the Sagittarius Dwarf, $ω$ Centari from Gaia-Enceladus/Sausage, NGC 6273 from Kraken and (potentially) NGC 6934 from the Helmi Streams. These NSCs are prime candidates for searches of intermediate mass black holes (BHs) within star clusters, given the common occurrence of galaxies hosting both NSCs and central massive BHs. No NSC appears to be associated with Sequoia or other minor accretion events. Other claimed NSCs are shown not to be such. We also discuss the peculiar case of Terzan 5, which may represent a unique case of a cluster-cluster merger.

description: This master thesis is focused on finding the minimum, necessary and sufficient buffer capacity to serial production lines with workstations which include parallel service facilities. The complexity of the industrial systems as well as the variations that occur in the design, development and operations make the specialized confrontation necessary. This assignment after an introductory presentation of operations research and industrial production systems, as well as the categories and the parameters of the production lines, refers to finding both graphically and algebraically the minimum, necessary and sufficient buffer capacity in order a desired throughput to be achieved. The examined system is a serial production line with two workstations constituted of reliable machines in parallel connection. The problem solving process was achieved by using the computer program Wolfram Mathematica 7.0. The program’s code is mentioned in the Annex and can find the solution to the pre-mentioned problem for any serial production line that satisfies the assumptions of this master thesis.

description: The Advanced Molybdenum-based Rare process Experiment in its second phase (AMoRE-II) will search for neutrinoless double-beta (0ν\b{eta}\b{eta}) decay of 100Mo in 200 kg of molybdate crystals. To achieve the zero-background level in the energy range of the double-beta decay Q-value of 100Mo, the radioactive contamination levels in AMoRE crystals should be low. 100EnrMoO3 powder, which is enriched in the 100Mo isotope, is used to grow the AMoRE crystals. A shielded array of fourteen high-purity germanium detectors with 70% relative efficiency each was used for the measurement of background activities in a sample of 9.6-kg powder. The detector system named CAGe located at the Yangyang underground laboratory was designed for measuring low levels of radioactivity from natural radioisotopes or cosmogenic nuclides such as 228Ac, 228Th, 226Ra, 88Y, and 40K. The activities of 228Ac and 228Th in the powder sample were 0.88 \pm 0.12 mBq/kg and 0.669 \pm 0.087 mBq/kg, respectively. The activity of 226Ra was measured to be 1.50 \pm 0.23 mBq/kg. The activity of 88Y was 0.101 \pm 0.016 mBq/kg. The activity of 40K was found as 36.0 \pm 4.1 mBq/kg.

description: Negative refraction is known to occur in materials that simultaneously possess a negative electric permittivity and magnetic permeability; hence they are termed negative index materials. However, there are no known natural materials that exhibit a negative index of refraction. In large part, interest in these materials is due to speculation that they could be used as perfect lenses with superresolution. We propose a new way of achieving negative refraction with currently available technology, based on transparent, metallo-dielectric multilayer structures. The advantage of these structures is that both tunability and transmission (well above 50%) can be achieved in the visible wavelength regime. We demonstrate both negative refraction and superresolution in these structures. Our findings point to a simpler way to fabricate a material that exhibits negative refraction. This opens up an entirely new path not only for negative refraction, but also to expand the exploration of wave propagation effects in metals.

description: The oil and gas industry is awash with sub-surface data, which is used to characterize the rock and fluid properties beneath the seabed. This in turn drives commercial decision making and exploration, but the industry currently relies upon highly manual workflows when processing data. A key question is whether this can be improved using machine learning to complement the activities of petrophysicists searching for hydrocarbons. In this paper we present work done, in collaboration with Rock Solid Images (RSI), using supervised machine learning on a Cray XC30 to train models that streamline the manual data interpretation process. With a general aim of decreasing the petrophysical interpretation time down from over 7 days to 7 minutes, in this paper we describe the use of mathematical models that have been trained using raw well log data, for completing each of the four stages of a petrophysical interpretation workflow, along with initial data cleaning. We explore how the predictions from these models compare against the interpretations of human petrophysicists, along with numerous options and techniques that were used to optimise the prediction of our models. The power provided by modern supercomputers such as Cray machines is crucial here, but some popular machine learning framework are unable to take full advantage of modern HPC machines. As such we will also explore the suitability of the machine learning tools we have used, and describe steps we took to work round their limitations. The result of this work is the ability, for the first time, to use machine learning for the entire petrophysical workflow. Whilst there are numerous challenges, limitations and caveats, we demonstrate that machine learning has an important role to play in the processing of sub-surface data.

A meta-analysis of the relationship between giftedness and life satisfaction
Creators: name: Strelzow, Lee-Ann
Publisher: name: University of British Columbia
Year: 2009

description: The focus of this paper is the quantitative synthesis of findings in selected literature on longitudinal gifted studies using 'meta-analysis.' In the existing literature there is a plethora of conflicting findings regarding occupational and life satisfaction of gifted individuals. Thus, a meta-analysis investigated the integration of the statistical results of these divergent findings. Nineteen studies were analyzed. The resulting 41 statistical results were transformed into a common effect size measure (ES), correlation coefficient. Using Validity Generalization Methodology, the corrected mean effect size for the relationship between giftedness and satisfaction was .14. When life and occupational satisfaction were separated into two separate effect size estimates, life satisfaction had a corrected mean ES of .10, and occupational satisfaction had a corrected mean ES of .19. No significant difference existed between men and women participants. The relationship of these two measures with giftedness was dependent on a number of variables. In order of strength they include: location of sample studied, location of sample drawn, and gender and age at time of study. Additionally, special school programs for gifted individuals had a mean effect of .10 and a standard deviation of .1. The implications of these findings are discussed in terms of current theories of intelligence and suggestions for further educational investigations are addressed.

description: Objectives:
Parasitic diseases prevail particularly among poor rural communities in Africa due to poor hygiene environment and threaten the live endanger the life of vulnerable people. This work aimed to assess the distribution of parasite infection with a focus on multiple infection among rural communities of Côte d'Ivoire.
Methods:
Stool sample were collected from human and screened using either Kato-Katz technique for soiltransmitted and intestinal schistosomiasis infection whilst ether concentration was used for intestinal protozoa infection. Urine sample collected were processed either using filtration technique or reagent strips for urinary schistosomiasis. In addition, a questionnaire was used to collect data pertaining to socioeconomic characteristics and capture factors that may foster parasites transmission.
Results:
Parasites were prevalent at the rate of 31.3%, 25.5% and 16.6% for Schistosoma; soil-transmitted helminth, and intestinal protozoa, respectively. Multiple infection was common at the rate of 27.4. This trend of poly infection was mainly driven by poverty, sex, age, crowding at household level, and absence of a toilet.
Conclusion:
Parasitic infection were prevalent in poor rural communities in Côte d’Ivoire and share risk factors such as poverty and poor hygiene condition favour poly infection. The results highlight the need of health intervention to mitigate the transmission.

description: We propose a scheme to generate double electromagnetically induced transparency and optimal cross-phase modulation for two slow, copropagating pulses with matched group velocities in a single species of atom, namely 87 Rb. A single pump laser is employed and a homogeneous magnetic field is utilized to avoid cancellation effects through the nonlinear Zeeman effect. We suggest a feasible preparational procedure for the atomic initial state to achieve matched group velocities for both signal fields.

description: Objectives
Human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection has poor treatment outcomes. Some HIV antiretroviral therapy (ART) drugs are also active against HBV meaning that people can be treated for both or infection with HBV prevented. We wanted to see if being on ART makes a difference to whether you catch hepatitis B.
Methods
Between 2013 and 2014, we enrolled 882 people in Entebbe or Kyambulibwa (Uganda) in a study to understand what happens when you take ART for 5 or more years. We collected information on many things including HBV infection which we diagnosed using blood tests. We wanted to see how many people taking ART caught hepatitis B and identify any risk factors.
Results
Overall, the number of people with HBV at the beginning of the study was lower in Kyamulibwa than Entebbe. Among the 289 people who didn’t have HBV when we started collecting data, we found 104 new HBV infections. New HBV infection was much less likely to happen if the ART regimen contained a drug called Tenofovir.

description: The quantum states corresponding to a secret key are characterized using the so-called private states, where the key part consisting of a secret key is shielded by the additional systems. Based on the construction, it was shown that a secret key can be distilled from bound entangled states. In this work, I consider the shielded two-qubit states in a key-distillation scenario and derive the conditions under which a secret key can be distilled using the recurrence protocol or the two-way classical distillation, advantage distillation together with one-way postprocessing. From the security conditions, it is shown that a secret key can be distilled from bound entangled states in a much wider range. In addition, I consider the case that in which white noise is added to quantum states and show that the classical distillation protocol still works despite a certain amount of noise although the recurrence protocol does not.

description: A quadrupole topological insulator, being one higher-order topological insulator with nontrivial quadrupole quantization, has been intensely investigated very recently. However, the tight-binding model proposed for such emergent topological insulators demands both positive and negative hopping coefficients, which imposes an obstacle in practical realizations. Here we introduce a feasible approach to design the sign of hopping in acoustics, and construct the first acoustic quadrupole topological insulator that stringently emulates the tight-binding model. The inherent hierarchy quadrupole topology has been experimentally confirmed by detecting the acoustic responses at the bulk, edge and corner of the sample. Potential applications can be anticipated for the topologically robust in-gap states, such as acoustic sensing and energy trapping.

description: Diseases caused by bacteria are of concern to mankind due to the deaths associated with these diseases. Incidentally, most of these diseases cannot be treated using the currently available drugs because the bacteria has adapted to withstand the fatal effect of these drugs. It has become necessary to develop new drugs that eliminate these modified bacteria and the diseases they cause. In this study, fungi growing on land and marine environment were isolated, grown in the laboratory and the agents they produced were tested against bacteria to ascertain whether these agents eliminated growth of the bacteria. We showed that 8% of the agents obtained from the fungi prevented bacterial growth by disrupting stability of the bacterial DNA. These agents either caused breaks in the bacterial DNA or prevented repair of these DNA breaks. The combination of these two categories of agents affecting bacterial DNA stability can be used to develop new drugs to replace the current drugs that have lost their ability to eliminate bacterial infections.

description: Objectives: The objective of this study was to provide a comprehensive description of the impact of health system arrangements as well as implementation strategies on the management of helminths, plasmodium, diabetes and hypertension.
Methods: The health care system was assessed in Taabo cité, Amani Ménou, and Tokohiri in the Taabo health district in Côte d’Ivoire in 2017. A systematic evaluation of health organizations, infrastructure, human resources and access to care was performed. Semi-structured interviews and focus group discussions were conducted with patients to estimate the cost of care of specific diabetes and hypertension.
Results:
Access to diagnostics and drugs at point of care remain a major challenge in the management of diabetes and hypertension in rural settings, on the contrary to malaria cases’ Schistosomiasis and helminth cases are channelled through mass drug administration provided by national programmes.
Conclusion: The availability of drugs, decentralised diagnostic tools, access to specialists, hygiene and dietetic measures and physical activities are the key features raised by the health workers
Energy and angular momentum densities of stationary gravity fields

description: We give physical explanations of explicit invariant expressions for the energy and angular momentum densities of gravitational fields in stationary space-times. These expressions involve non-locally defined conformal factors. In certain coordinates these become locally defined in terms of the metric. These results are derived via expressions for total gravitational potential energy from the difference between the total energy and the mechanical energy. The latter involves kinetic energy seen in the frame of static observers. When in the axially symmetric case we consider zero angular momentum observers (who move orthogonally to surfaces of constant time), we find that the angular momentum they attribute to the gravitational field is solely due to their motion.

description: Objectives: To examine how iron deficiency (ID) affects development of natural protection against malaria infections and how well malaria vaccines work in children.
Methods: We measured levels of 2 malaria antibodies and iron status markers in Kenyan (n=964) and Ugandan (n=870) children. We also measured malaria vaccine responses in children vaccinated with RTSS,S’ (n=115) and ME-TRAP vaccines (n=91). Children were classified as iron deficient or not using low ferritin (as defined by WHO) and / or low transferrin saturation (TSAT).
Results: Overall, we found that levels of the two malaria antibodies were lower in iron deficient (low ferritin) compared to non-deficient children. Using the low TSAT definition, only one malaria antibody was lower in the iron deficient children. There was no significant difference in the response of RTSS vaccine between the two groups of children. ME-TRAP vaccine response was higher in iron deficient children six months after
vaccination.
Conclusions: The lower malaria antibody levels observed in children with ID may decrease their protection and recovery from malaria. Further research is required to investigate the relationship between ID and vaccine responses in African children.
Strong enhancement of magnetic order from bulk to stretched monolayer FeSe as Hund's metals

description: Despite of the importance of magnetism in possible relation to other key properties in iron-based superconductors, its understanding is still far from complete especially for FeSe systems. On one hand, the origin of the absence of magnetic orders in bulk FeSe is yet to be clarified. On the other hand, it is still not clear how close monolayer FeSe on SrTiO$_3$, with the highest transition temperature among iron-based superconductors, is to a magnetic instability. Here we investigate magnetic properties of bulk and monolayer FeSe using dynamical mean-field theory combined with density-functional theory. We find that suppressed magnetic order in bulk FeSe is associated with the reduction of inter-orbital charge fluctuations, an effect of Hund's coupling, enhanced by a larger crystal field splitting. Meanwhile, spatial isolation of Fe atoms in expanded monolayer FeSe leads into a strong magnetic order, which is completely destroyed by a small electron doping. Our work provides a comprehensive understanding of the magnetic order in iron-based superconductors and other general multi-orbital correlated systems as Hund's metals.

description: Η εξέλιξη των συστημάτων ασύρματης επικοινωνίας, όπως αυτή διαμορφώνεται από τη συνεχώς αυξανόμενη ζήτηση για νέες υπηρεσίες, καθιστά τις τρέχουσες πολιτικές διαμοίρασης του φάσματος ανίκανες να ανταπεξέλθουν σε αυτή, δημιουργώντας προβλήματα έλλειψης του διαθέσιμου φάσματος. Πρόσφατες μετρήσεις δείχνουν ότι μεγάλα τμήματα του φάσματος που έχουν εκχωρηθεί σε συγκεκριμένα συστήματα υπο-χρησιμοποιούνται. Τα Γνωστικά Συστήματα Ραδιοεπικοινωνιών (Cognitive Radio Systems) είναι συστήματα τα οποία εκμεταλλεύονται με δυναμικό τρόπο τα φασματικά κενά. Μια από τις πιο σημαντικές προκλήσεις της νέας αυτής προσέγγισης είναι η Ανίχνευση Φάσματος (Spectrum Sensing). Η δική μας μελέτη επικεντρώθηκε στη παρουσίαση των τεχνικών ανίχνευσης φάσματος, και εστιάσαμε στην απόδοση του Ανιχνευτή Ενέργειας (Energy Detector), τόσο σε θεωρητικό όσο και σε πρακτικό επίπεδο μέσω ποικίλων προσομοιώσεων που πραγματοποιήσαμε. Συγκεκριμένα, μελετήθηκε ο ανιχνευτής ενέργειας με περιοδόγραμμα Welch σε σήματα τόνου και BPSK σε θόρυβο AWGN. Επιπλέον, εξετάστηκαν διάφορα σενάρια ανίχνευσης φάσματος με σκοπό να μελετηθεί το πρόβλημα του κρυμμένου τερματικού (Hidden Node Problem) και η συνεργατική ανίχνευση (Cooperative Spectrum Sensing).
description: The grand evolution of wireless communication systems following the growing demand for new services, requires new spectrum access policies. Recent research has demonstrated the fact that significant portions of the radiofrequency spectrum that has been licensed to specific wireless systems, is under-utilized. Cognitive Radio Systems are in concept intelligent systems that make use of the spectrums holes. One of the most important and crucial challenge of that new approach is the precise and proper spectrum sensing. Our study is focused on the presentation of the most widely used spectrum sensing techniques, and specifically on the performance of the Energy Detector, both on an analytical and on a numerical basis through various simulations that have been performed using matlab. In particular, the energy Detector using Welch Periodogram has been examined using sinusoids and BPSK signal in Additive White Gaussian. Detection in a typical fast fading Rayleigh channel was studied. In addition, various sensing scenarios were examined in order to explore the impact of the Hidden Node Problem on the detection probability and the Cooperative Spectrum Sensing as a means to counteract it.

description: Accurate and thorough characterization of the chemistry of compounds containing the third-row elements sulfur and chlorine is critical for modeling the composition of the atmosphere of Venus. We have used a combination of ab initio quantum chemistry and kinetic theory to characterize a group of nine exothermic reactions that involve the exotic sulfur-chlorine species SCl, SCl2, and HSCl, which are thought to be present in trace quantities in the atmosphere of Venus and are included to various degrees in the published atmospheric models. Reaction pathways were characterized with coupled cluster theory at the RCCSD(T) level with triple zeta quality correlation consistent basis sets. For reactions with barriers that lie above the reactant asymptote, the barrier height was extrapolated to the RCCSD(T) complete basis set level via single-point calculations with quadruple and quintuple zeta quality sets. Rate coefficients were predicted with capture theory and transition state theory as appropriate. We have found that in some cases addition-elimination reactions can compete with abstraction reactions due to the tendency of sulfur to form hypervalent compounds and intermediates via recoupled pair bonding.

description: The One Health (OH) concept has become an integral part of an effective health system. We conducted a gap analysis to identify ways to improve the implementation using the OH. The main challenges are leadership claims at the onset of collaboration. We also observed slow pace of operationalization due to insufficient resources allocation and share. We show the usefulness of economic analyses for motivation and behavior change in public and animal health

description: This paper is based on an “Automatic Robotic System” which will have the faculty to collect elements in anyone space we determine and with the conception that it possesses to distinguish them will offer precious help – briefing on the new materials – elements that it found. This hole presentation suggests a method based on projects for the introduction and use of programmable robotic constructions in secondary school education. The theoretical background of the methodology is constructivism and especially the ideas of constructionism. The system LegoMindstorms NXT is the basic tool used to support the suggested educational activities of robotics. The system offers a variety of structural elements to be used for mechanical constructions and a functional graphical programming environment, through which behaviours are assigned to the mechanical constructions.
