title: High Mass X-ray Binaries: The Donor Stars and their Compact Companions
Creators: name: Baker, Amira Val
Publisher: name: The Open University
Year: 2008

description: This thesis presents new spectroscopic observations of the donor star in several High Mass X-ray Binary systems. The various types of X-ray Binary systems that exist are outlined and the methods and limitations of mass determination of the stellar components are discussed. The masses of the compact objects are determined for the systems SMC X-1 and LMC X-3. In both cases the heating of the donor star by the X-ray source is taken into account and its importance demonstrated.

In the case of SMC X-1, we determine the radial velocity semi-amplitude of Sk 160 to be 24.7 ± 1.9 km s-1. Assuming Sk 160 fills its Roche-lobe we obtain upper limits for the mass of the neutron star as Mx = 1.36 ± 0.10, and by assuming that the system is seen edge on we obtain lower limits for the masses of the neutron star as Mx = 1.05 ± 0.09 M⊙. However, based on the model predictions of Timmes et al. (1996), it is concluded that the mass lies in the upper end of the heating corrected mass determinations.

In the case of LMC X-3 the spectral type of the donor star is observed to change with phase due to irradiation by the X-ray source. We find the spectral type is likely to be B5V, and only appears as B3V when viewing the heated side of the donor. Combining our measurements with those previously published, and taking into account the effects of X-ray irradiation, results in a value for the donor star radial velocity semi-amplitude of Ko = 256.7±4.9 km s-1. Assuming an inclination of 50° ≤ i ≤ 70° we find the mass of the black hole lies in the range 9.5 ± 1 M⊙ ≤ Mx ≤ 13.2 ± 1 M⊙.

The idea of using these mass determination techniques as a tool for detecting potential black hole/Be star XRB systems is presented and the radial velocities for seven such systems are determined. Of these, one system, LS 4356 shows a radial velocity variation large enough (i.e. ~ 95 km s-1) to indicate the presence of a black hole. If the compact companion is confirmed as a black hole, it will make LS 4356 the first known black hole/Be XRB. Finally the emission lines observed in the spectra of two Be XRBs, X Per and A0535+26 are analysed and compared to the previous studies of Clark et al. (2001) and Grundstrom et al. (2007). The Hα emission line profiles are discussed in terms of their evolution with time and the changing state of the circumstellar disc, thereby confirming and adding to the long term data set. The emission line profiles of the other spectral lines, namely Hβ, H-γ, He I 5876, He I 6678 and He I 7065, are presented and compared with that of Hα.

description: One of the challenging problems in the condensed matter physics is to understand the quantum many-body systems, especially, their physical mechanisms behind. Since there are only a few complete analytical solutions of these systems, several numerical simulation methods have been proposed in recent years. Amongst all of them, the Tensor Network algorithms have become increasingly popular in recent years, especially for their adaptability to simulate strongly correlated systems. The current work focuses on the generalization of such Tensor-Network-based algorithms, which are sufficiently robust to describe critical phenomena and phase transitions of multistate spin Hamiltonians in the thermodynamic limit. We have chosen two algorithms: the Corner Transfer Matrix Renormalization Group and the Higher-Order Tensor Renormalization Group. This work, based on tensor-network analysis, opens doors for the understanding of phase transition and entanglement of the interacting systems on the non-Euclidean geometries. We focus on three main topics: A new thermodynamic model of social influence, free energy is analyzed to classify the phase transitions on an infinite set of the negatively curved geometries where a relation between the free energy and the Gaussian radius of the curvature is conjectured, a unique tensor-based algorithm is proposed to study the phase transition on fractal structures.

description: While spatial boundaries include the geographic differences among team members (e.g., different cities), temporal boundaries include the workday differences among team members (e.g., different time zones). In global teams, members have to deal with both spatial and temporal boundaries, since their co-workers are often located in cities within and across time zones. For global team members with high spatial boundaries and low temporal boundaries (e.g., different cities in the same time zone), synchronous communication technologies such as the telephone and instant messenger provide a means for real-time interaction. However, for global team members with high spatial boundaries and high temporal boundaries (e.g., different cities in different time zones), asynchronous communication technologies such as e-mail and web software provide a way to interact intermittently. Using social network data from 625 team members (representing 5986 pairs) across 137 global teams in a multi-national semiconductor firm, we explore the impact of spatial and temporal boundaries on coordination delay. We also illustrate how member awareness can reduce coordination delay, thus increasing the likelihood of better global team performance.

description: There are two ways of understanding child development. The first places emphasis on the human cultural dimension. The essential component of culture is a system of cultural norms known as “ideal forms,” wherein the adult acts as a bearer of these ideal forms or culture. From this standpoint, the child acquires already established forms (in this sense, old norms). The second approach is based on understanding the child’s infinite and unlimited capabilities. The realization of such opportunities, due to their unlimited nature, involves going beyond the zone of proximal development. This requires conceptualizing a different space, oriented to new forms of culture that are not yet in existence—the space of child realization. The orientation of this space is the opposite to that of the zone of proximal development: instead of an old norm being acquired (i.e., the adaptation of the child to their culture) the goal for an adult is, in the space of child realization, to help the child realize their intent by creating new elements of culture.

description: In our former work (Sci. Rep. 4: 6039, 2014), we theoretically and numerically demonstrated that chaotic oscillation can be induced in a nanoscale system consisting of quantum dots between which energy transfer occurs via optical near-field interactions. Furthermore, in addition to the nanoscale implementation of oscillators, it is intriguing that the chaotic behavior is associated with probability derived via a density matrix formalism. Indeed, in our previous work (Sci. Rep. 6: 38634, 2016) we examined such oscillating probabilities via diffusivity analysis by constructing random walkers driven by chaotically driven bias. In this study, we experimentally implemented the concept of probability chaos using a single-photon source that was chaotically modulated by an external electro-optical modulator that directly yielded random walkers via single-photon observations after a polarization beam splitter. An evident signature was observed in the resulting ensemble average of the time-averaged mean square displacement. Although the experiment involved a scaled-up, proof-of-concept model of a genuine nanoscale oscillator, the experimental observations clearly validate the concept of oscillating probability, paving the way toward future ideal nanoscale systems.

description: The epic poem begins with a brief genealogy of the Danes. Scyld Shefing was the first great king of the Danes, known for his ability to conquer enemies. Scyld becomes the greatgrandfather of Hrothgar, the king of the Danes during the events of Beowulf. Hrothgar, like his ancestors before him, is a good king, and he wish to celebrate his reign by building a grand hall called Heorot. Once the hall is finished, Hrothgar holds a large feast. The revelry attracts the attentions of the monster Grendel, who decides to attack during the night. In the morning, Hrothgar and his thanes discover the bloodshed and mourn the lost warriors. This begins Grendel's assault upon the Danes and ends with the feats of Beowulf and his fight with the monstor dragon and its death and his saga.

description: From a Chandra survey of nine interacting galaxy systems the evolution of X-ray emission during the merger process has been investigated. From comparing Lx/Lk and Lfir/Lb it is found that the X-ray luminosity peaks around 300 Myr before nuclear coalescence, even though we know that rapid and increasing star formation is still taking place at this time. It is likely that this drop in X-ray luminosity is a consequence of outflows breaking out of the galactic discs of these systems. At a time around 1 Gyr after coalescence, the merger-remnants in our sample are X-ray dim when compared to typical X-ray luminosities of mature elliptical galaxies. However, we do see evidence that these systems will start to resemble typical elliptical galaxies at a greater dynamical age, given the properties of the 3 Gyr system within our sample, indicating that halo regeneration will take place within low Lx merger-remnants.

description: The Oslo sandpile model, or if one wants to be precise, ricepile model, is a cellular automaton designed to model experiments on granular piles displaying self-organized criticality. We present an analytic treatment that allows the calculation of the transition probabilities between the different configurations of the system; from here, using the theory of Markov chains, we can obtain the stationary occupation distribution, which tell us that the phase space is occupied with probabilities that vary in many orders of magnitude from one state to another. Our results show how the complexity of this simple model is built as the number of elements increases, and allows, for a given system size, the exact calculation of the avalanche size distribution and other properties related to the profile of the pile.

description: Modern businesses require a suite of appropriate analytical tools – both quantitative and qualitative – that go beyond data mining, because of issues with scalability, parallelizability, and numeric vs. symbolic representation that may well affect analytic utility and the results of an analytic. However, there is limited formal or structured guidance for new and complex problem spaces providing criteria for what analytics to use and how they are to be cascaded or integrated to obtain useful results and generate a range of alternate explanations of what is happening now, what is likely to happen soon, and what could happen in the long term. In this paper, we describe sixteen classes of analytics in which we extend previous work by Kaisler and Cioffi-Revilla [7]. We examine some issues and implementation challenges for analytics in the global business environment. We suggest several applications of these analytics to modern business problems and draw several conclusions that lead to further research.

description: We report on the XMM-Newton (XMM) observation of RXJ1053.7+5735, one of the most distant X-ray selected clusters of galaxies, which also shows an unusual double-lobed X-ray morphology, indicative of a possible equal-mass cluster merger. The cluster was discovered during the ROSAT deep pointings in the direction of the Lockman Hole. All XMM Lockman Hole observations (PV, AO-1 & AO-2 phases) with the European Photon Imaging Camera (EPIC) were combined for the analysis, totaling exposure times ~ 648 ks, 738 ks, and 758 ks for pn, MOS1, and MOS2, respectively. With this 'deep' dataset, we could detect the Fe K line and obtain a strong constraint on cluster metallicity, which is difficult to achieve for clusters at z > 1. The best-fit abundance is 0.46 +0.11/-0.07 times the solar value. The Fe line emission also allows us to directly estimate the redshift of diffuse gas, with a value z = 1.14 +0.01/-0.01. This is one of the first clusters whose X-ray redshift is directly measured prior to the secure knowledge of cluster redshift by optical/NIR spectroscopy. We could also estimate the X-ray redshift separately for each of the two lobes in the double-lobed structure, and the result is consistent with the two lobes being part of one cluster system at the same redshift. Comparison with other metallicity measurements of nearby and distant clusters shows that there is little evolution in the ICM metallicity from z ~ 1 to the present.

description: Within linear continuum theory, no magnetic texture can propagate faster than the maximum group velocity of its spin waves. Here we report a transient regime due to the appearance of additional antiferromagnetic textures that breaks the Lorentz translational invariance of the magnetic system by atomistic spin dynamics simulations. This dynamical regime is akin to domain wall Walker-breakdown in ferromagnets and involves the nucleation of an antiferromagnetic domain wall pair. Subsequently, one of the nucleated 180$^{\circ}$ domain wall creates with the original domain wall a 360$^{\circ}$ spin-rotation which remains static even under the action of the spin-orbit field. The other 180$^{\circ}$ domain wall becomes accelerated to super-magnonic speeds. Under large spin-orbit fields, multiple domain wall generation and recombination is obtained which may explain the recently experimentally observed current pulse induce shattering of large domain structures into small fragmented domains and the subsequent slow recreation of large-scale domain formation prior current pulse.

description: Interpersonal interactions during childhood form the foundation for development and learning (Tomasello, 2014; Vygotsky, 1962, 1978). Numerous studies have documented the impact of interactions between preschool teachers and preschool-aged children between 3 and 6 years of age (e.g., Denham et al., 2003; Hamre, Hatfield, Pianta & Jamil, 2013). The aims of this 1-year observational study were to investigate patterns of interaction between professional preschool teachers and children between 10 and 24 months of age in Danish crèches and to examine the correlations between these interaction patterns and preschool teachers’ pedagogical decisions. The study indicates that internal pedagogical choices (extent of reflection and planning for the pedagogical activities; criteria for groupings of children; whether preschool teachers worked predominantly alone with smaller groups of children or as a team of two or three with several children)—decisions that differ from crèche to crèche—are crucial. These pedagogical decisions are mutually dependent on or sensitive to the child–adult ratio. The study reveals significant differences in the character of the interpersonal interactions between teachers and children, according, for example, to the level of planning and pedagogical reflections. This may cause different conditions for children’s cultural learning and development.
An Evaluation of Sensing Fat Depth for the Automation of Uniform Fat Trimming of Beef Striploin

description: The trimming of excess fat from beef striploin primal is currently a manual process costing the Australian beef industry an estimated $89 million annually due to yield losses within beef processing plants. Robotics have been successfully deployed to address efficiency and productivity issues in similar products such as pork but are yet to be adapted to red meat. Specifically, a sensing technology capable of acquiring the fat depth information required for automated trimming is yet to be developed.

The work undertaken in this dissertation investigates the characteristics of the beef striploin primal and the processing considerations to develop a sensing performance framework for the application of beef striploin fat trimming. Computed-Tomography is used to provide a means of benchmarking the error present between manual measurements and the 'gold standard' of sensing technologies for this application in the performance metrics of accuracy (described as median error), precision (described as Inter-Quartile Range of error), linearity (described as R-squared quantity of actual vs predicted measurements), reliability (described as the expected probability of acquiring 'no read' measurements across surveyed nodes), and response time (described as the time required to acquire measurements). A weighted sensor performance evaluation framework was developed based upon analyses conducted on key aspects of the striploin primal fat profile and the fat specifications and operational constraints of the fat trimming process.

Fat depth measurement systems were developed using A-Mode and B-Mode ultrasound sensing technologies to obtain results that could be assessed using the developed weighted sensor evaluation framework. In applying this framework it was identified that the A-Mode (score: 47 / 75) ultrasound system was more suitable than B-Mode (score: 29 / 75) for ii implementation within a commercial automated fat trimming system. Though the majority of literature recommends the use of B-Mode ultrasound for fat depth measurements it was found that the performance metrics considered favoured simplicity and fast response typical of A-mode ultrasound technology.

Further work to validate the recommendation of A-Mode ultrasound technologies for uniform fat trimming of beef striploin is recommended by integrating this technology within an automated system for commercial use.

We consider the limit where the conduction electron density is equal to the localized electron density, which is the limit related to the S_z=0 states of the Hubbard model. After considering over 20,000 different candidate phases (with a unit cell of 16 sites or less) and their thermodynamic mixtures, we find only about 100 stable phases in the ground-state phase diagram. We analyze these phases to describe where stripe phases occur and relate these discoveries to the physics behind stripe formation in the Hubbard model.

Bioethics in popular science : evaluating the media impact of The Immortal Llife of Henrietta Lacks on the biobank debate

description: Background: The global expansion of biobanks has led to a range of bioethical concerns related to consent, privacy, control, ownership, and disclosure. As an opportunity to engage broader audiences on these concerns, bioethicists have welcomed the commercial success of Rebecca Skloot’s 2010 bestselling book The Immortal Life of Henrietta Lacks. To assess the impact of the book on discussion within the media and popular culture more generally, we systematically analyzed the ethics-related themes emphasized in reviews and articles about the book, and in interviews and profiles of Skloot. Methods: We conducted a content analysis of a population of relevant English-language articles and transcripts (n = 125) produced by news organizations and publications in the U.S., Canada, Great Britain/Ireland, and Australia/ New Zealand. We scored each article for the emphasis and appearance of 9 ethics-related themes. These were informed consent, welfare of the vulnerable, compensation, scientific progress, control/access, accountability/ oversight, privacy, public education, and advocacy. Results: The informed consent theme dominated media discussion, with almost 39.2 percent of articles/transcripts featuring the theme as a major focus and 44.8 percent emphasizing the theme as a minor focus. Other prominent themes and frames of reference focused on the welfare of the vulnerable (18.4 percent major emphasis; 36.0 percent minor emphasis), and donor compensation (19.2 percent major; 52.8 percent minor). Ethical themes that comprised a second tier of prominence included those of scientific progress, control/access, and accountability/ oversight. The least prominent themes were privacy, public education, and advocacy. Conclusions: The book has been praised as an opportunity to elevate media discussion of bioethics, but such claims should be re-considered. The relatively narrow focus on informed consent in the media discussion generated by Skloot’s book may limit the ability of ethicists and advocates to elevate attention to donor control, compensation, patenting, privacy, and other ethical issues. Still, ethicists should view the book and a pending major TV film translation as opportunities to highlight through media outreach, consultation exercises and public forums a broader range of bioethical concerns that would otherwise be under-emphasized in news coverage. Such efforts, however, need to be carefully planned and evaluated.

title: The future of Responsive Facade for multi-storey residential buildings in tropical climates
Creators: name: Souza, Paloma
Publisher: name: University of Southampton
Year: 2022
Subjects: responsive facades, multi-storey residential building, building performance, user comfort, energy efficiency

description: The design study seeks to comprehend the principles and elements of a Responsive Facade and how they affect energy efficiency and user comfort for space cooling for multi-story residential buildings in tropical climates. The research is based on precedent studies, occupant behavior, and a critical analysis of challenges in existing building facades, having Brazil as case study. Identifies the different factors that interfere in the environmental conditions and building performance to build parameters that will optimize facade design proposals. As a result, a variety of facade features were put into place, with ceramic being the main material utilized to make perforated and opaque panels that function as shading and permeable envelope. Furthermore, the dynamic operation was investigated through automated elements that move in response to the sun or under occupant's control. In order to maximize performance in tropical conditions, a variety of intervention scenarios were examined.
title: The effect on learners strategies of varying computer-based representations: evidence from gazes, actions, utterances and sketches

description: Computer-based Multiple External Representations (MERs) have been found in some cases to help and in others to hinder the learning process. This thesis examines how varying the external representations that are presented in a computer environment influences the strategies that learners choose when tackling mathematics tasks. It has been noted (Ainsworth, 2006) that learners fail to transfer insights from one representation to another. Previous work analysing video data of learners' problem-solving with computer-based MERs emphasises the need to identify which representation is being considered by a learner as utterances are made, and to examine more closely learners' movement between representations. This research focuses on the relationship between strategy and representation during learners' problem solving. A set of analytical techniques was developed to characterise learner strategies, to identify how different computer-based MERs influence strategy choices, and to explore how these choices change over the course of task completion. Rich data were collected using a variety of technologies: learners' shifts in attention were recorded using an unobtrusive eye-tracking device and screen capture software; keyboard and mouse actions were logged automatically; utterances and gestures were video recorded; notes and sketches were recorded in real-time using a Tablet PC. This research suggests how integrated analysis of learners' gazes, actions, writing, sketches and utterances can better illuminate subtle cognitive strategies. The study involved completion of three tasks by eighteen participants using multiple mathematical representations (numbers, graphs and algebra) presented in different computer-based 'instantiations': Static (non-moving, non-changing, non-Interactive); Dynamic (capable of animation following keyboard inputs); Interactive (directly manipulable using a mouse). Having computer-based MERs available to learners provides an opportunity to use representations with which they are comfortable. A detailed analysis showed that both representation and instantiation have an impact on strategy choice. It identified differences in expression of inferences, construction of visual images, and attention to representations between different types of instantiation. One of the important findings of the research is that learners are less likely to use imagining strategies when representational instantiation is Interactive. These results may provide some explanation of how interactivity helps or hinders learners' understanding of multiple representations.

description: Objetivou-se, neste trabalho, encontrar viabilidade técnico-econômica para a formação da cadeia de processamento do soro de queijo, recuperando seu valor enquanto matéria-prima para produtos nobres. Com base nas informações dos 92 laticínios localizados em 52 municípios de Minas Gerais, o problema aqui tratado, da localização de unidade de beneficiamento do soro de queijo e identificação dos respectivos fornecedores, envolve a sugestão do local para instalação da indústria que minimiza os custos de obtenção do soro resfriado e/ou pré-concentrado para o processamento, bem como os valores que viabilizam o empreendimento. A partir dos indicadores de logística, foram agregados critérios outros de caráter financeiro para a análise do empreendimento. Além da indicação da implantação de unidades de beneficiamento do soro de queijo, ficou também constatado que os custos internos não são competitivos, atualmente, frente à oportunidade de importação do soro de queijo, sendo que tal situação coloca um desafio para as empresas dessa cadeia agroindustrial e também para os entes governamentais. ---- This study aimed to find technical and economic viability for the formation of the processing chain of whey, retrieving its value as a raw material for special products. Based on information from 92 dairies located in 52 cities of Minas Gerais State, it was suggested the location of processing units of whey – and identification of its suppliers – that minimizes the costs involved in the acquisition and processing, as well as the values that makes the enterprise viable. Logistics and financial indicators were combined in the analysis of the enterprise. The results indicate strong challenges to this agribusiness chain and government entities due to the fact that costs of whey logistics and processing are high in Brazil when compared to imported whey.
Bioethics in popular science : evaluating the media impact of The Immortal Llife of Henrietta Lacks on the biobank debate
Creators: name: Nisbet, Matthew C.

Publisher: name: American University
Year: 2023

description: Background: The global expansion of biobanks has led to a range of bioethical concerns related to consent, privacy, control, ownership, and disclosure. As an opportunity to engage broader audiences on these concerns, bioethicists have welcomed the commercial success of Rebecca Skloot’s 2010 bestselling book The Immortal Life of Henrietta Lacks. To assess the impact of the book on discussion within the media and popular culture more generally, we systematically analyzed the ethics-related themes emphasized in reviews and articles about the book, and in interviews and profiles of Skloot. Methods: We conducted a content analysis of a population of relevant English-language articles and transcripts (n = 125) produced by news organizations and publications in the U.S., Canada, Great Britain/Ireland, and Australia/ New Zealand. We scored each article for the emphasis and appearance of 9 ethics-related themes. These were informed consent, welfare of the vulnerable, compensation, scientific progress, control/access, accountability/ oversight, privacy, public education, and advocacy. Results: The informed consent theme dominated media discussion, with almost 39.2 percent of articles/transcripts featuring the theme as a major focus and 44.8 percent emphasizing the theme as a minor focus. Other prominent themes and frames of reference focused on the welfare of the vulnerable (18.4 percent major emphasis; 36.0 percent minor emphasis), and donor compensation (19.2 percent major; 52.8 percent minor). Ethical themes that comprised a second tier of prominence included those of scientific progress, control/access, and accountability/ oversight. The least prominent themes were privacy, public education, and advocacy. Conclusions: The book has been praised as an opportunity to elevate media discussion of bioethics, but such claims should be re-considered. The relatively narrow focus on informed consent in the media discussion generated by Skloot’s book may limit the ability of ethicists and advocates to elevate attention to donor control, compensation, patenting, privacy, and other ethical issues. Still, ethicists should view the book and a pending major TV film translation as opportunities to highlight through media outreach, consultation exercises and public forums a broader range of bioethical concerns that would otherwise be under-emphasized in news coverage. Such efforts, however, need to be carefully planned and evaluated.

description: The transverse resistivity in thin films of La(0.84)Sr(0.16)MnO(3) (LSMO)exhibits sharp field-symmetric jumps below Tc. We show that a likely source of this behavior is the giant planar Hall effect (GPHE) combined with biaxial magnetic anisotropy. The effect is comparable in magnitude to that observed recently in the magnetic semiconductor Ga(Mn)As. It can be potentially used in applications such as magnetic sensors and non-volatile memory devices.

description: We present the results of deep near-infrared observations of 11 hard X-ray selected sources in the Hellas2XMM survey, with faint optical magnitude (R>24) and high X-ray-to-optical flux ratio. All but one of the sources have been detected in the Ks band, with bright counterparts (Ks<19) and red colors (R-K>5), and therefore belong to the ERO population. A detailed analysis of the surface brightness profiles allows us to classify all of the NIR counterparts. There are 2 point-like objects, 7 elliptical galaxies and one source with a disky profile. None of the extended sources shows any evidence for the presence of a central unresolved object tracing the putative X-ray emitting AGN. Using both the R-K colors and the morphological information, we have estimated for all the sources a ``minimum photometric redshift'', ranging between 0.8 and 2.4; the elliptical hosts have zmin=0.9-1.4. We computed the X-ray properties using these redshifts: most of the sources have NH>10^{22}, with unabsorbed X-ray luminosities up to 10^{45}erg s^{-1}. These objects therefore belong to the population of obscured (Type II) quasars and, from a statistical point of view, they turn out to be a non-negligible fraction (~10%) of the most luminous AGN. Selecting the high X/O sources for a follow-up study in the NIR is therefore a powerful technique aimed at studying at high redshift the hosts of Type II AGN. Overall, our results seem to indicate that the hosts are mostly elliptical galaxies at z~1, and that these near-IR bright objects would be among the most massive spheroids at these epochs.
