description: Binary supermassive black holes (SMBH) are expected to form naturally during galaxy mergers. After the dynamical friction phase, when the two SMBHs become gravitationally bound to each other, and a brief stage of initial rapid hardening, the orbit gradually continues to shrink due to three-body interactions with stars that enter the loss cone of the binary. Using the stellar-dynamical Monte Carlo code Raga, we explore the co-evolution of the binary SMBH and the nuclear star cluster in this slow stage, for various combinations of parameters (geometry of the star cluster, primary/secondary SMBH mass, initial eccentricity, inclusion of stellar captures/tidal disruptions). We compare the rates of stellar captures in galactic nuclei containing a binary to those of galaxies with a single SMBH. At early times, the rates are substantially higher in the case of a binary SMBH, but subsequently they drop to lower levels. Only in triaxial systems both the binary hardening rates and the capture rates remain sufficiently high during the entire evolution. We find that the hardening rate is not influenced by star captures, nor does it depend on eccentricity; however, it is higher when the difference between the black hole masses is greater. We confirm that the eccentricity of the binary tends to grow, which may significantly shorten the coalescence time due to earlier onset of gravitational-wave emission. We also explore the properties of the orbits entering the loss cone, and demonstrate that it remains partially full throughout the evolution in the triaxial case, but significantly depleted in the axisymmetric case. Finally, we study the distribution of ejected hypervelocity stars and the corresponding mass deficits in the central parts of the galaxies hosting a binary, and argue that the missing mass is difficult to quantify observationally.

description: In this work a series of artificial neural networks (ANNs) have been developed with the capacity to estimate an obstacle's size and location obstructing the flow in a pipe. The ANNs learn the size and location of the obstacle by reading the profiles of the dynamic pressure $q$ or the $x$-component of the velocity $v_x$ of the fluid at certain distance from the obstacle. The data to train the ANN, was generated using numerical simulations with a 2D Lattice Boltzmann code. We analyzed various cases varying both the diameter and position of the obstacle on $y$-axis, obtaining good estimations using the $R^2$ coefficient for the cases of study. Although the ANN showed problems for the classification of the very small obstacles, the general results show a very good capacity of prediction.

description: In this study we combine the background and the growth rate data in order to study the ability of the two oscillating dark energy parameterizations, to fit the observational data. Using the likelihood and MCMC method we try to explore the posterior space and put constraints on the free parameters of the models. Based on the values of the well known Akaike and Bayesian information criteria we find that both of oscillating dark energy models considered in this work are disfavored by the combined (background+growth rate) data. Although using the expansion data we can not reject oscillating dark energy models, the combined analysis provides strong evidences against these models.

description: This article investigates whether fixed-term employment affects the realization of important partnership events. We are looking at four transitions: entering cohabitation, marriage, parenthood and home ownership. Data were obtained from a random sample of 1,083 young German adults aged 20 to 35 years based on the AGIPEB Survey. We use the Kaplan-Meier method and piecewise-constant exponential models to estimate survival curves and transition rates. Women and men who work under a fixed-term contract are similarly likely to enter cohabitation, marriage and parenthood as persons who work under a permanent contract. In contrast, fixed-term employment compared to working under a permanent contract prolongs the transition into home ownership. Zusammenfassung In diesem Beitrag wird untersucht, ob befristete Beschäftigungsverhältnisse die Realisierung zentraler Partnerschaftsereignisse beeinflussen. Hierfür untersuchen wir vier Übergänge: Eintritt in die Kohabitation, Eheschließung, Elternschaft und Erwerb von Immobilieneigentum. Die Daten wurden aus einer Zufallsstichprobe mit 1.083 jungen deutschen Erwachsenen auf Basis des AGIPEB-Survey gewonnen. Wir wenden die Kaplan-Meyer-Methode und piecewise-constant exponential models an, um Überlebenskurven und Übergangsraten zu schätzen. Frauen und Männer, die in einem befristeten Beschäftigungsverhältnis arbeiten, neigen in ähnlicher Weise wie Personen mit einem unbefristeten Arbeitsvertrag dazu, die Kohabitation zu beginnen, die Ehe zu schließen und Eltern zu werden. Im Gegensatz dazu verzögert das Arbeiten unter befristeten Verträgen ‒ im Vergleich zum Arbeiten unter unbefristeten Verträgen ‒ jedoch den Übergang zum Erwerb von Wohnungseigentum.

description: Strong piezoelectricity in the perovskite-type PbZr(1-x)TixO3 (PZT) and Pb(Zn1/3Nb2/3)O3-PbTiO3 (PZN-PT) systems is generally associated with the existence of a morphotropic phase boundary (MPB) separating regions with rhombohedral and tetragonal symmetry. An x-ray study of PZN-9%PT has revealed the presence of a new orthorhombic phase at the MPB, and a near-vertical boundary between the rhombohedral and orthorhombic phases, similar to that found for PZT between the rhombohedral and monoclinic phases. We discuss the results in the light of a recent theoretical paper by Vanderbilt and Cohen, which attributes these low-symmetry phases to the high anharmonicity in these oxide systems.

description: We analyze the frequency-dependent current fluctuations induced into a gate near a quantum point contact or a quantum chaotic cavity. We use a current and charge conserving, effective scattering approach in which interactions are treated in random phase approximation. The current fluctuations measured at a nearby gate, coupled capacitively to the conductor, are determined by the screened charge fluctuations of the conductor. Both the equilibrium and the non-equilibrium current noise at the gate can be expressed with the help of resistances which are related to the charge dynamics on the conductor. We evaluate these resistances for a point contact and determine their distributions for an ensemble of chaotic cavities. For a quantum point contact these resistances exhibit pronounced oscillations with the opening of new channels. For a chaotic cavity coupled to one channel point contacts the charge relaxation resistance shows a broad distribution between 1/4 and 1/2 of a resistance quantum. The non-equilibrium resistance exhibits a broad distribution between zero and 1/4 of a resistance quantum.

description: We study the intrinsic shapes of a sample of over 400 quiescent galaxies in the cores of the Virgo and Fornax clusters with luminosities $10^{6} \leq L_{g}/L_{\odot} \leq 10^{8}$. Similar to satellites of the Local Group and Centaurus A, these faint, low surface brightness cluster galaxies are best described as a family of thick ($C/A > 0.5$), oblate-triaxial spheroids. However, the large sample size allows us to show that the flattening of their stellar distributions depends both on luminosity and on the presence of a nuclear star cluster. Nucleated satellites are thicker at all luminosities compared to their non-nucleated counterparts, and fainter galaxies are systematically thicker as well, regardless of nucleation. Once nucleation is accounted for, we find no evidence that the environment the satellites live in plays a relevant role in setting their three-dimensional structure. We interpret both the presence of stellar nuclei and the associated thicker shapes as the result of preferential early and rapid formation, effectively making these faint nucleated galaxies the first generation of cluster satellites.

description: Jelly seed disorder is one of the major problems in mango production in Kenya as well as other mango producing countries in the world. This physiological disorder known as jelly seed which manifests itself through breakdown of tissues around the seed thus lowering the marketability of the affected fruits. This problem manifests itself through breakdown of tissues around the seed of the affected fruits resulting in unmarketable fruits. Although the exact cause of jelly seed in mango is unknown, some reports indicate that the condition could be due to imbalance related to Ca, Mg, N and K supply to the fruit. To establish the extent of this problem in Kenya, a study was conducted in 2013 in three major mango producing counties located in different agro-ecological zones namely Embu, Murang’a and Meru. Three farms with homogenous trees of “Tommy Atkins” and “Van Dyke” mangoes were randomly selected per county. Soil and mango leaf analysis were carried out to determine the nutrient status. Rainfall and temperature data were also recorded during the study period. At harvest time, 50 tree-ripe fruits of each variety were randomly sampled from 25 trees per site and sliced along the endocarp to expose the seed then visually examined and scored for the incidence of jelly seed using Galan Sauco scale. Soil analysis showed that, Meru vertisol and lithosols soils had higher Ca, Mg, K content compared to Murang’a eutric Nitisol soils and Embu ferralic arenosal soils. Similarly, mango leaves and fruits sampled from Meru county had higher Ca, Mg and K contents than those from Murang’a and Embu. Fruits (both varieties) from Embu county showed higher incidents of jelly seed that those from Murang’a and Meru county. Significantly higher jelly seed incidents were reported in ‘Van Dyke’ compared to ‘Tommy Atkins’ mangoes. It can therefore be concluded hat incidences of jelly seed depend on the variety as well as agro-ecological zone where the mangoes are produced.

description: Most of the current state-of-the-art methods for tumor segmentation are based on machine learning models trained on manually segmented images. This type of training data is particularly costly, as manual delineation of tumors is not only time-consuming but also requires medical expertise. On the other hand, images with a provided global label (indicating presence or absence of a tumor) are less informative but can be obtained at a substantially lower cost. In this paper, we propose to use both types of training data (fully-annotated and weakly-annotated) to train a deep learning model for segmentation. The idea of our approach is to extend segmentation networks with an additional branch performing image-level classification. The model is jointly trained for segmentation and classification tasks in order to exploit information contained in weakly-annotated images while preventing the network to learn features which are irrelevant for the segmentation task. We evaluate our method on the challenging task of brain tumor segmentation in Magnetic Resonance images from BRATS 2018 challenge. We show that the proposed approach provides a significant improvement of segmentation performance compared to the standard supervised learning. The observed improvement is proportional to the ratio between weakly-annotated and fully-annotated images available for training.

description: Many parts of South Asia are facing agricultural land degradation and reduced productivity while the population continues to grow and demand for food is ever-increasing. This paper presents the results of research specifically focused on application of biochar and Farm Yard Manure (FYM) at 5t/ha and 20t/ha, respectively as an amendment on degraded soil in a coffee agroforestry system of the mid-hills in the Nepal Himalaya. The study showed that there were significant (P<0.05) positive effects on soil chemical properties, crop growth (height) and crop productivity. In particular, the soil pH and SOM increased significantly, while other soil properties were not significantly improved. Also, plant growth increased dramatically with application of biochar, however, crop yields showed only slight increases. It is suggested that biochar applied at low rates along with FYM generally has immediate positive effects on the vegetative growth of plants, however, soil properties and overall crop yields may take a longer time to show improvement. Soil biophysical and chemical quality is critically important for sustaining the crop productivity and protecting the environment.

description: The emergence of Community Justice Courts (CJC) in the UK is a relatively new approach to doing justice. Founded upon the broad principles of community justice they present a challenge to traditional criminal justice practice. This thesis is based on a qualitative ethnographic study, employing an interpretivist methodology to develop knowledge and understanding of the Plymouth CJC. Furthermore it sought to review three specific areas, firstly the operations of the CJC and whether these processes varied from those of traditional magistrates’ court, secondly the development and operationalisation of problem-solving multi-agency working, and thirdly the identification and implementation of community engagement strategies. Observations of the court and associated meetings were undertaken (29 court sessions, six meetings, two problem-solving meetings) alongside interviews with 11 respondents representing the key stakeholder groups, documentary analysis of all meeting information and available guidance on the court, two small focus groups with Devonport and Stonehouse residents (independently) and self-completion questionnaire data from defence solicitors and offenders, all of which was analysed by constant comparison. Findings suggest that there were only two areas of distinction between the CJC and traditional magistrates’ court, those being court-based problem-solving and increased magistrate interaction. In addition, multi-agency problem-solving was evident but hounded by cultural and political differences in ideology and operations, leading to considerable resistance by court based legal professions. Furthermore, community engagement was found to be in need of considerable attention. Consequently recommendations for change and future research at policy, organisation and practitioner level have been made. The study concludes by suggesting that more time is needed for these courts to prove themselves and further attention could be given to applying the principles to mainstream court processes without the added expense of a specialist model.

description: We use the modified propagator for quantum field based on a ``principle of path integral duality" proposed earlier in a paper by Padmanabhan to investigate several results in QED. This procedure modifies the Feynman propagator by the introduction of a fundamental length scale. We use this modified propagator for the Dirac particles to evaluate the first order radiative corrections in QED. We find that the extra factor of the modified propagator acts like a regulator at the Planck scales thereby removing the divergences that otherwise appear in the conventional radiative correction calculations of QED. We find that:(i) all the three renormalisation factors $Z_1$, $Z_2$, and $Z_3$ pick up finite corrections and (ii) the modified propagator breaks the gauge invariance at a very small level of ${\mathcal{O}}(10^{-45})$. The implications of this result to generation of the primordial seed magnetic fields are discussed.

description: This thesis examines the operability of three completely different, in terms of design, naval vessels with the use of an absolute seakeeping performance assessment method. The sea environment considered is that of four Eastern Mediterranean Sea areas , belonging to the Aegean Sea. Ships' responses are measured for two speeds and three angles of encounter. The S.M.P. code is used in order to calculate the motions and derived criteria at eight points onboard each ship. Criteria sets for four essential operations (TAP "Transit And Patrol", ASW "Anti-Submarine Warfare", AAW "Anti-Air Warfare" and NAO "Naval Air Operations") and found in ΝΑΤΟ STANAG 4154 Edition 3 are used to assess the overall mission performance of each ship. Environmental data were taken from the wind and wave atlas, which was created by the Western European Armaments Organisation Research Cell released in 2004, with the participation of the N.T.U.A. This atlas provides statistical data accumulated over a ten-year period. Finally, the results are presented by means of Cartesian Coordinates, although a common practice is to use polar diagrams.

description: We propose and study a simple model of dynamical redistribution of capital in a diversified portfolio. We consider a hypothetical situation of a portfolio composed of N uncorrelated stocks. Each stock price follows a multiplicative random walk with identical drift and dispersion. The rules of our model naturally give rise to power law tails in the distribution of capital fractions invested in different stocks. The exponent of this scale free distribution is calculated in both discrete and continuous time formalism. It is demonstrated that the dynamical redistribution strategy results in a larger typical growth rate of the capital than a static ``buy-and-hold'' strategy. In the large N limit the typical growth rate is shown to asymptotically approach that of the expectation value of the stock price. The finite dimensional variant of the model is shown to describe the partition function of directed polymers in random media.

description: We study peculiarities of transport through a Coulomb blockade system tuned to the vicinity of the spin transition in its ground state. Such transitions can be induced in practice by application of a magnetic field. Tunneling of electrons between the dot and leads mixes the states belonging to the ground state manifold of the dot. Remarkably, both the orbital and spin degrees of freedom of the electrons are engaged in the mixing at the singlet-triplet transition point. We present a model which provides an adequate theoretical description of recent experiments with semiconductor quantum dots and carbon nanotubes.

description: We present detailed photoionization models of well aligned optically thin C III absorption components at $2.1 < z < 3.4$. Using our models we estimate density ($n_{\rm \tiny H}$), metallicity ($[C/H]$), total hydrogen column density and line-of-sight thickness ($L$) in each C III components. We estimate the systematic errors in these quantities contributed by the allowed range of the quasar spectral index used in the ultraviolet background radiation calculations. Our inferred $n_{\rm \tiny H}$ and overdensity ($Δ$) are much higher than the measurements available in the literature and favor the absorption originating from gas associated with circumgalactic medium and probably not in hydrostatic equilibrium. We also notice $n_{\rm \tiny H}$, $L$ and $[C/H]$ associated with C III components show statistically significant redshift evolution. To some extent, these redshift evolutions are driven by the appearance of compact, high $n_{\rm \tiny H}$ and high $[C/H]$ components only in the low$-z$ end. We find more than 5$σ$ level correlation between $[C/H]$ and $L$, $L$ and neutral hydrogen column density (N (HI)), N (HI) and $[C/H]$. We show $L$ versus $[C/H]$ correlation can be well reproduced if $L$ is governed by the product of gas cooling time and sound speed as expected in the case of cloud fragmentation under thermal instabilities. This allows us to explain other observed correlations by simple photoionization considerations. Studying the optically thin C III absorbers over a large $z$ range and probably correlating their $z$ evolution with global star formation rate density evolution can shed light into the physics of cold clump formation and their evolution in the circumgalactic medium.

description: The addition to the Hubbard Hamiltonian of a t' diagonal hopping term, which is considered to be material dependent for high-Tc cuprate superconductors, is generally suggested to obtain a model capable to describe the physics of high-Tc cuprate materials. In this line of thinking, the two-dimensional t-t'-U model has been studied by means of the Composite Operator Method, which allows to determine the dynamics in a fully self-consistent way by use of symmetry requirements, as the ones coming from the Pauli principle. At first, some local quantities have been calculated to be compared with quantum Monte Carlo data. Then, the structure of the energy bands, the shape of the Fermi surface and the position of the van Hove singularity have been computed as functions of the model parameters and studied by the light of the available experimental data. The results of our study show that there exists two sets of parameters that allows the model to describe the relevant features of 1-layer compounds NCCO and LSCO. On the other hand, for the 2-layer compound YBCO is not possible to find a reasonable set of parameters which could reproduce the position of the van Hove singularity as predicted by ARPES experiments. Hence, it results questionable the existence of an unique model that could properly describe the variety of cuprate superconductors, as the t-t'-U model was thought to be.

description: SOLICITED - Female Earth-scientists have existed in the 19th century and the first half of the 20th century, in a number exceeding what we generally imagine. The causes of this oblivion about their work, their personalities, and the obstacles they met to pursue their studies and research, could enlighten the persisting unequal gender balance in Earth sciences and the struggles of female geoscientists today. In the same way many past female artists are since a few years rediscovered, scientists women tend to be more and more taken out of the dustbin of History. This huge task is already undertaken by a few persons. Before giving the main results of the review of their research, as well as some fresh contribution to this collective work in progress, the method will be detailed, as this particular subject needs some specific attentions, e.g. the consultation of not only scientific literature, but also of popularization blogs; the use of each name found to look for potential others (coauthors, teachers, students). Finally when confronted to an apparent vacuum, i.e. a geographical area or a geoscience subject counting apparently no female scientists before the 1930's, we should look deeper into it. Indeed as is well known in Earth sciences, « absence of evidence is not evidence of absence ». Common mechanisms that have first made these women work a challenge, and then hidden their figures, are discrimination, including difficult access to university and academic positions, and the attribution of their own work to men they worked with or for. They found several ways to overcome these difficulties: thanks to the support of their parents, or to the more ambiguous support of husbands or academic male mentors, through celibacy, and through team work with and/or mentorship by other women.

description: We present results obtained from the analysis of a total of 110 ks Chandra observations of 3C 320 FR II radio galaxy, located at the centre of a cluster of galaxies at a redshift $z=0.342$. A pair of X-ray cavities have been detected at an average distance of $\sim$38 kpc along the East and West directions with the cavity energy, age and total power equal to $\sim$7.7$\times$10$^{59}$ erg, $\sim$7$\times$10$^7$ yr and $\sim$3.5$\times$10$^{44}$ erg s$^{-1}$, respectively. The cooling luminosity within the cooling radius of $\sim$100 kpc was found to be $L_{cool} \sim8.5\times10^{43}$ erg s$^{-1}$. Comparison of these two estimates implies that the cavity power is sufficiently high to balance the radiative loss. A pair of weak shocks have also been evidenced at distances of $\sim$47 kpc and $\sim$76 kpc surrounding the radio bubbles. Using the observed density jumps of $\sim$1.8 and $\sim$2.1 at shock locations along the East and West directions, we estimate the Mach numbers ($\mathcal{M}$) to be $\sim$1.6 and $\sim$1.8, respectively. A sharp surface brightness edge was also detected at relatively larger radius ($\sim$80 kpc) along the South direction. Density jump at this surface brightness edge was estimated to be $\sim$1.6 and is probably due to the presence of a cold front in this cluster. The far-infrared luminosity yielded the star formation rate of 51 M$_{\odot}$ yr$^{-1}$ and is 1/4$^{th}$ of the cooling rate ($\dot{M}$ $\sim$ 192 M$_{\odot}$ yr$^{-1}$).

description: MacMahon showed that the generating function for partitions into at most $k$ parts can be decomposed into a partial fractions-type sum indexed by the partitions of $k$. In this present work, a generalization of MacMahon's result is given, which in turn provides a full combinatorial explanation.

title: Epidemiology of Staphylococcus aureus carriage and disease among under five children in rural Gambia
Creators: name: Odutola, A
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Background: Data on the burden of severe Staphylococcus aureus disease, a significant cause of invasive bacterial infections among children aged <5 years in The Gambia and Africa at large, are lacking. The work in this thesis estimates the burden (cases and deaths) of severe S. aureus disease in Africa, the incidence of S. aureus bacteraemia (SAB) in children aged <5 years and assesses the risk factors for neonatal S. aureus acquisition in rural Gambia. Methods: This thesis includes three separate studies. First, following a systematic literature review and meta-analysis, raw and processed data were synthesised to estimate the numbers of cases and deaths due to severe S. aureus diseases in children aged <5 years in Africa. Second, the incidence and case fatality ratio (CFR) of SAB in <5 years Gambian children were estimated from a population-based study. Lastly, a longitudinal study of newborn-contact pairs was used to evaluate the risk factors associated with neonatal S. aureus carriage at birth as well as with its acquisition at one-week of age. Results: In Africa, an estimated 392,066 cases and 46,467 deaths due to severe S. aureus disease occurred among children aged <5 years with 20.4% and 58.4% of these occurring among neonates, respectively in 2015. The incidence of SAB among Gambian children aged <5 years and neonates was 78/100,000 person-years (95%CI 67–91) and 3.5/1,000 live-births (95%CI 2.9–4.7), respectively. The CFR was 14.1% (95%CI 9.6-19.8). S. aureus carriage at birth was associated with the midwife’s report of handwashing before delivery while carriage acquisition one week after delivery was associated with maternal and household child nasal carriage. Conclusion: The burden of severe S. aureus disease among children aged <5 years in Africa is substantial. Developing new, and implementing existing, strategies urgently to tackle this will contribute to achieving the sustainable development goals.
Kaluza-Klein Formalism of General Spacetimes
Creators: name: Yoon, J. H.
Publisher: name: arXiv
Year: 2000
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: I describe the Kaluza-Klein approach to general relativity of 4-dimensional spacetimes. This approach is based on the (2,2)-fibration of a generic 4-dimensional spacetime, which is viewed as a local product of a (1+1)-dimensional base manifold and a 2-dimensional fibre space. It is shown that the metric coefficients can be decomposed into sets of fields, which transform as a tensor field, gauge fields, and scalar fields with respect to the infinite dimensional group of the diffeomorphisms of the 2-dimensional fibre space. I discuss a few applications of this formalism.
