Mothering in multicultural context: experiences of Filipino immigrant mothers in Calgary
Creators: name: Hertzsprung, Emerenciana A.
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 140-153
description: Both mothering and culture are recognized within psychology as playing important, sometimes crucial roles in psychological and social development, and are thus important areas of research. This project uses a discursive approach to examine how Filipino immigrant mothers to Canada approach and negotiate their experience of raising Canadian children: how do they talk about culture and motherhood? How do they position themselves in relation to their Filipino heritage and to the host Canadian culture? From which cultural resources and mothering ideologies do they draw, and how do they use or resist these resources and ideologies through their use of language? Eleven Filipino immigrant mothers volunteered to participate in five separate conversation sessions during which we talked about culture and mothering. The conversations were then audiotaped and transcribed for discursive analysis. I identify and discuss two broad issues that emerged in our conversations. Firstly, whatever the topic of discussion happened to be, an important concern of the mothers was to take up and justify subject positions with regard to 'good' mothering. Further, in attempts to resolve the tension between versions of the 'good' mother, the participant mothers oriented themselves to questions of presence and absence: does a 'good' mother have to be physically present to her children? Can physical absence from one's children be constructed as consistent with being a 'good' mother? Secondly, the importance of honouring both host and heritage cultures was evident in our conversations, particularly at moments when approval or censure of either culture were expressed. Participant mothers were careful not to be so loyal to Filipino heritage as to appear ungrateful to Canada, or so grateful to Canada as to betray Filipino heritage. Ways in which the current project arises from, contributes to, and extends existing literature on culture and mothering are discussed.
Vision-Based Condition Monitoring of Lubricated Gearboxes

Publisher: name: Zenodo
Year: 2022

description: Gears are widely used in many different applications. Their condition is often monitored using indirect measurements (vibrations, temperature, oil analysis) or periodic visual inspection. However, if these current systems could be aided by a real-time automated vision system, gear defects could be detected much earlier on. This early detection is one of the cornerstones for applications of gears in industries such as wind energy. To realize such a vision system a back-to-back gear tester (FZG) is being installed with a vision-based condition monitoring system. This system will allow for further research to better understand the initiation and spatio-temporal evolution of gear surface defects. Secondly, it will allow for improvements in current conditioning monitoring techniques and subsequently maintenance strategies. Finally, this research can help towards the development of a visual monitoring system that can be installed in vital applications such as wind energy.

description: We construct a hydrodynamic theory of noisy, apolar active smectics, in bulk suspension or on a substrate. Our predictions include: quasi-long-ranged smectic order in dimension d = 2, and long- ranged in d = 3, extending previously published results to all dynamical regimes; Kosterlitz-Thouless melting to an active nematic at high and low concentrations in d = 2; nonzero second-sound speed parallel to the layers; the suppression of giant number fluctuations by smectic elasticity; instability to spontaneous undulation and flow in bulk contractile smectics; a layer spacing instability, possibly oscillatory, for large enough extensile active stresses.

Evolution of neural networks for gait animation
Creators: name: Hickey, Craig
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 58-61
description: In this thesis, we describe efforts to create a system that automatically produces realistic real-time animations of walking figures. In traditional computer graphics, the animator is forced to use intuition about the physical world in specifying the motions of objects in a scene, but manual control techniques have generally proven to be unsatisfactory for realism. The use of dynamics greatly improves motion realism and shifts control of the animation from specifying absolute positions of objects to applying forces and torques to the objects in the scene. This is a much more difficult task for a human to control, whereas a neural network is well suited for this task. Through the use of a genetic algorithm, one can determine the performance of a neural network as a whole, and select for whatever behavior is desired. Animator control is then directed through model design and behavior choices.

Waiting for a space in an adult day support program: retrospective caregiver perspectives
Creators: name: Hildebrandt, Clare Rachel
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 124-136
description: Adult Day Support Programs (ADSPs) are designed to give caregivers of individuals with dementia respite; however, there is little empirical evidence into the burden borne by caregivers who wait for community based health services. A cross-sectional, retrospective questionnaire was used to assess the levels of burden, stress, depression, self esteem and the perceived impact of waiting for an ADSP of caregivers of individuals who attended dementia-specific ADSPs in the Calgary Health Region. The response rate for perceived, expected, and acceptable waiting times was insufficient to draw conclusions; however, thirty percent of caregivers found that the waiting period allowed them to adapt to the use of ADSPs, compared with twenty-five percent who found that waiting for ADSP services was associated with an increase in stress level. Waiting time did not have an association with current caregiver burden. These results support further investigation into the effects of waiting for community based health services.

description: Screaming-channel attacks enable Electromagnetic (EM) Side-Channel Attacks (SCAs) at larger distances due to higher EM leakage energies than traditional SCAs, relaxing the requirement of close access to the victim. This attack can be mounted on devices integrating Radio Frequency (RF) modules on the same die as digital circuits, where the RF can unintentionally capture, modulate, amplify, and transmit the leakage along with legitimate signals. Leakage results from digital switching activity, so the hypothesis of previous works was that this leakage would appear at multiples of the digital clock frequency, i.e., harmonics. This work demonstrates that compromising signals appear not only at the harmonics and that leakage at non-harmonics can be exploited for successful attacks. Indeed, the transformations undergone by the leaked signal are complex due to propagation effects through the substrate and power and ground planes, so the leakage also appears at other frequencies. We first propose two methodologies to locate frequencies that contain leakage and demonstrate that it appears at non-harmonic frequencies. Then, our experimental results show that screaming-channel attacks at non-harmonic frequencies can be as successful as at harmonics when retrieving a 16-byte AES key. As the RF spectrum is polluted by interfering signals, we run experiments and show successful attacks in a more realistic, noisy environment where harmonic frequencies are contaminated by multi-path fading and interference. These attacks at non-harmonic frequencies increase the attack surface by providing attackers with an increased number of potential frequencies where attacks can succeed.

description: B. C.'s coastal forest products firms and campaigning environmental non­governmental organizations (ENGOs) had been engaged in an intense conflict for many years over the management and use of the Province's coastal temperate rainforests. In 2000, in response to marketplace pressures and public policy failures, the two sides laid down their arms and established a strategic alliance for developing innovative new approaches for sustainably managing the coastal forests. The outcome of the alliance was a new knowledge base for sustainable forest management. This research presents a three­stage model of knowledge creation based on a firm-civil society alliance.

description: Due to the development of technology, everything in our life is getting easier day by day. In addition, a few years ago hospitality business was hardly a topic of academic or commercial interest. However, providing the largest networked accommodation service, Airbnb is now a surprising major hotel chain such as Hilton and other five-star hotels. In addition, Airbnb’s market valuation also surprises financial activities hence, people keep investing in Airbnb. On the other hand, Airbnb grows digital platforms that show a structure of social changes. For example, allowing a complete stranger to staying a person’s own house. Furthermore, some Airbnb offers services such as airport pickup, etc which is establishing a strong bond between people. From the business point of view, short-stay holiday rentals by private individuals and entrepreneurs establish a professional hotel business that is making a positive impact on the economy.

description: We use new Suzaku observations of PKS 0745-191 to measure the thermodynamic properties of its ICM out to and beyond r_{200} (reaching 1.25r_{200}) with better accuracy than previously achieved, owing to a more accurate and better understood background model. We investigate and resolve the tensions between the previous Suzaku and ROSAT results for PKS 0745-191, which are found to be principally caused by incorrect background modelling in the previous Suzaku analysis. We investigate in depth the systematic errors affecting this observation, and present temperature, density, entropy and gas mass fraction profiles reaching out to and beyond the virial radius. We find that the entropy profile flattens in the outskirts as originally observed in the previous Suzaku analysis, but that the flattening starts at larger radius. The flattening of the entropy profile and our mass analysis suggests that outside ~17' (~1.9 Mpc) the ICM is out of hydrostatic equilibrium or the presence of significant non-thermal pressure support.

description: Oral cancer causes a significant disease burden and financial distress, especially among disadvantaged groups. While Malaysia has achieved universal health coverage via its highly subsidized public healthcare, household expenditure for treatment of oral potentially malignant disorders (OPMD) and oral cancer remains a concern in the equitability of care. This study aims to estimate the extent of catastrophic healthcare expenditure (CHE) while identifying its cost drivers. This three-part study consists of a prospective cross-sectional survey to collect health utilization data of patients, a retrospective medical record abstraction to identify resources consumed, and cost estimation modeling in two tertiary public hospitals. Out-of-pocket (OOP) payments for transport, care in public healthcare facilities, and other healthcare expenditures were tallied. CHE was defined as OOP spendings of more than 10% from total annual household income. Multivariate binary logistic regression was further applied to identify the association between sociodemographic factors and CHE. A total of 104 patients were surveyed and their medical records abstracted. A Kruskal-Wallis test showed a statistically significant difference in OOP share over household income between OPMD, early- and late-stage oral cancer, χ2(2)=51.05, p<0.001, with the mean percentage of 9%, 22%, and 65% respectively. This study found that the prevalence of CHE in the first year of diagnosis was staggering at 86.5% for oral cancer and 19.2% for OPMD. Race (Indian) (OR=7.4, p=0.035) and active employment (OR=0.07, p=0.035) were shown as significant predictors for CHE. Our study demonstrated the provision of current subsidies may not be adequate to shield the more vulnerable group from CHE.

A qualitative study of resiliency in women with a history of childhood sexual abuse
Creators: name: Hinton, Monica Jay
Publisher: name: Social Work
Year: 2004

description: Bibliography: p. 105-116
description: The purpose of this qualitative study was to uncover what participants believed fostered their resiliency. Volunteers responded to a university e-mail flyer, through word of mouth and through snowball sampling and were interviewed by a qualitative research method known as the guided interview. Data were analyzed using grounded theory, which includes open coding, axial coding and selective coding. The chosen central phenomenon was the perception that the participants' childhood sexual abuse was traumatic and three categories of strategies used to address this phenomenon were identified. These categories include: regulating the traumatic experience, enlisting important individuals/pets and spirituality. Comparisons among participants showed that many of the same strategies were used to remain resilient, including humour, self­preservation, imagination, choice and 'unhealthy' strategies. The results indicated that there are degrees of resiliency, that resiliency is a process and that participants shared similarities and they also shared differences.

description: In their rocksalt structure, rare-earth monosulfides offer a more stable alternative to alkali metals to attain low or negative electron affinity when deposited on various III-V and II-VI semiconductor surfaces. In this article, we first describe the successful deposition of Lanthanum Monosulfide via pulsed laser deposition on Si and MgO substrates and alumina templates. These thin films have been characterized by X-ray diffraction, atomic force microscopy, high resolution transmission electron microscopy, ellipsometry, Raman spectroscopy, ultraviolet photoelectron spectroscopy and Kelvin probe measurements. For both LaS/Si and LaS/MgO thin films, the effective work function of the submicron thick thin films was determined to be about 1 eV from field emission measurements using the Scanning Anode Field Emission Microscopy technique. The physical reasons for these highly desirable low work function properties were explained using a patchwork field emission model of the emitting surface. In this model, nanocrystals of low work function materials having a <100> orientation perpendicular to the surface and outcropping it are surrounded by a matrix of amorphous materials with higher work function. To date, LaS thin films have been used successfully as cold cathode emitters with measured emitted current densities as high as 50 A/cm2. Finally, we describe the successful growth of LaS thin films on InP substrates and, more recently, the production of LaS nanoballs and nanoclusters using Pulsed Laser Ablation.

Oxymethylene Ethers as Fossil Fuel Alternative to Reach Carbon Neutrality

Year: 2022

description: More than a quarter of the global greenhouse gas emissions are related to the transportation sector and, therefore, a major revamp of this sector is required to comply with the Paris Climate Agreement objectives. Our research focuses on combined modeling and experimental work on combustion of oxymethylene ethers (OMEs). These molecules form a promising family of synthetic fuels, which can be produced starting from CO2 via carbon capture and utilization technology with renewable electricity, so-called e-fuels. OMEs consist of alternating carbon and oxygen bonds in the backbone saturated with hydrogen (structural formula CH3O(CH2O)nCH3), instead of alternating carbon-carbon bonds in the case of fossil-based fuels. OMEs are compatible with the current generation of diesel engines and blending them with conventional diesel fuels reduces the soot emissions significantly because of the absence of carbon-carbon bonds. As such, OMEs and OME-diesel blends result in less harmful emissions and can contribute to a more sustainable transportation sector on the short term due to the transition towards a circular carbon economy. To promote the use of these molecules, it is important to understand their low- and high-temperature combustion chemistry. Detailed microkinetic models have been developed systematically with in-house developed automatic kinetic model generation code ‘Genesys’ to gain fundamental insight into the decomposition chemistry. Quantum chemical calculations are performed on the HPC to unravel the OME decomposition pathways, and to obtain both accurate thermodynamic and kinetic parameters for species and reactions, respectively. New experimental data is obtained from a variety of experimental units to validate the constructed models under a broad set of conditions. Our kinetic models will enable predictive simulations to optimize the combustion and allow global deployment in heavy-duty transportation for which electrification is unfeasible.

description: We present modeling and interpretation of the continuum and emission lines for a sample of 51 unobscured Type 1 active galactic nuclei (AGN). All of these AGNs have high quality spectra from both XMM-Newton and Sloan Digital Sky Survey (SDSS). We extend the wavelength coverage where possible by adding simultaneous UV data from the OM onboard XMM-Newton. Our sample is selected based on low reddening in the optical and low gas columns implied by their X-ray spectra. They also lack clear signatures for the presence of a warm absorber. Therefore the observed characteristics of this sample are likely to be directly related to the intrinsic properties of the central engine. We perform multi-component spectral fitting for strong optical emission lines and the whole optical spectra. We fit the combined optical, UV and X-ray data by applying a new broadband SED model which comprises the accretion disc emission, low temperature optically thick Comptonisation and a hard X-ray tail by introducing the a corona radius (Done et al. 2011). We find that in order to fit the data, the model often requires an additional long wavelength optical continuum component, whose origin is discussed in this paper. We also find that the Photo-recombination edge of Balmer continuum shifts and broadens beyond the standard limit of 3646Å, implying an electron number density which is far higher than that in the broad line region clouds. Our results indicate that the Narrow Line Seyfert 1s in this sample tend to have lower black hole masses, higher Eddington ratios, softer 2-10 keV band spectra, lower 2-10 keV luminosities and higher α_{ox}, compared with typical broad line Seyfert 1s (BLS1), although their bolometric luminosities are similar. We illustrate these differences in properties by forming an average SED for three subsamples, based on the FWHM velocity width of the Hβ emission line.

description: Nowadays complex building designs, new construction materials and everchanging layout of the buildings all stress the difficulty to properly address evacuation in modern buildings. There has been a shift away from the legislation-based set of rules (prescriptive approach) towards a performance-based approach to fire safety engineering. One of the challenges is determining the attained level of fire and life safety. The project will realise coupling between the BIM model and fire engineering practice allowing for an iterative data-based fire and life safety strategy to be put into place, which can be adapted during the lifetime of the building, considering data from evacuation exercises and CFD simulations.
A practical buses protocol for anonymous network communication

description: Bibliography: p. 156-161
description: The need to communicate anonymously over the Internet has increased with the proliferation of networked computers. Applications such as military communications, Web browsing, e-voting, and e-counseling for victims of abuse all require anonymous communication. Without anonymity, individuals may refrain from communicating for fear of retribution, potentially resulting in social, psychological, or financial losses, or even the loss of life. This thesis contains a comprehensive survey and analysis of anonymous commu­nication schemes. Analysis of the prior literature shows that there is no secure and scalable anonymous communication scheme. Previous literature has only analyzed each scheme for a subset of the known attacks. In this thesis, the analysis is extended to assess the anonymity capabilities of these schemes with respect to all known at­tacks. It is shown that none of the scalable anonymous communication schemes are secure. The thesis contains a description of the design, implementation, and evaluation of a prototype anonymous communication scheme. The Buses anonymity protocol is identified as the most secure and scalable candidate protocol for a dynamic network topology. The protocol is re-designed and extended into the Practical Buses protocol, with features added to protect against all of the known attacks in the literature. New techniques are introduced to make the protocol scalable while preserving mutual anonymity. The design is extended to make the protocol more efficient, secure, and fault-tolerant. The experimental results obtained demonstrate that the Practical Buses protocol is a promising solution for anonymous network communication.

description: We introduce a generalized scaling law, M_tot = 10^K A^a B^b, to look for the minimum scatter in reconstructing the total mass of hydrodynamically simulated X-ray galaxy clusters, given gas mass M_gas, luminosity L and temperature T. We find a locus in the plane of the logarithmic slopes $a$ and $b$ of the scaling relations where the scatter in mass is minimized. This locus corresponds to b_M = -3/2 a_M +3/2 and b_L = -2 a_L +3/2 for A=M_gas and L, respectively, and B=T. Along these axes, all the known scaling relations can be identified (at different levels of scatter), plus a new one defined as M_tot ~ (LT)^(1/2). Simple formula to evaluate the expected evolution with redshift in the self-similar scenario are provided. In this scenario, no evolution of the scaling relations is predicted for the cases (b_M=0, a_M=1) and (b_L=7/2, a_L=-1), respectively. Once the single quantities are normalized to the average values of the sample under considerations, the normalizations K corresponding to the region with minimum scatter are very close to zero. The combination of these relations allows to reduce the number of free parameters of the fitting function that relates X-ray observables to the total mass and includes the self-similar redshift evolution.

In order to achieve this task, it has been essential to determine the structure of the separable superselection sectors that arise owing to the polymeric quantization, and to prove that the initial value problem obtained when regarding the Hamiltonian constraint as an evolution equation, interpreting the volume as the evolution parameter, is well-posed.

Interpreting workplace learning in terms of discourse and community of practice
Creators: name: Ho, J. Adrian Kim-Fat
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 118-140
description: Based on the ethnographic data collected from the workplace of an academic library, I argue that workplace learning (WL) is a situated socio-cognitive process. It is expedited by knowledge management (KM), which is a collective effort to generate, share, and institutionalize work-related knowledge. KM is inherent in the face-to-face conversational interactions embedded in planned formal training, planned informal sharing, and spontaneous informal learning. When face-to-face interaction is not possible, KM is accomplished through textualization. It helps the members of the workplace acquire new work-related knowledge and integrate it to their common, contextualized knowledge base. The contents of the knowledge base are manifested in the members' professional practices and explicated by their professional/communal discourse.

description: Evaluating urban infrastructures through computer models is a useful way of gath­ering feedback and improving a proposed design before finally implementing it in concrete. Many current models focus on vehicular traffic, to the detriment of pedes­trians. To address this shortcoming, this thesis contributes a multi-agent model of vehicular and pedestrian traffic, where agents can plan, adapt and execute, produc­ing statistical feedback, and an intuitive visualization. This includes a description of how the environment is represented and how the agents plan and execute. Through the use of a software prototype, analysis of traffic flow is explored in several simple scenarios, highlighting the effect of agent variations. Through a model of the Uni­versity campus, a more realistic and holistic scenario is analysed, demonstrating the applicability and limitations of the model.

description: Η παρούσα διπλωματική εργασία αφορά στη σχεδιαστική πρόταση ανάπλασης και επανάχρησης της Σεβαστοπουλείου Σχολής με νέα χρήση κατοικίες, που θα λειτουργούν ως χώροι προσωρινής φιλοξενίας για γυναίκες θύματα βίας και τα παιδιά τους. Το κτίριο, που βρίσκεται στην οδό Π. Κυριακού στην περιοχή των Κουντουριώτικων, δημιουργήθηκε στις αρχές του 20ού αιώνα για να στεγάσει την πρώτη σχολή τεχνικών επαγγελμάτων στην Ελλάδα. Έπειτα ακολούθησαν περαιτέρω προσθήκες και λειτούργησε ως ημερήσιο και εσπερινό επαγγελματικό λύκειο, ενώ τα τελευταία χρόνια παραμένει εγκαταλελειμμένο. Η ιδέα για την προτεινόμενη χρήση στη συγκεκριμένη θέση απορρέει από την πρόσφατη ιστορία, με την ύπαρξη του Αναμορφωτηρίου Θηλέων, το οποίο βρισκόταν στη γειτονιά και σε πολύ κοντινή απόσταση από το κτιριακό συγκρότημα που μελετάμε και λειτούργησε ως χώρος καταπίεσης και βίας εναντίον νεαρών γυναικών. Σκοπός μας είναι η εφαρμογή διαφόρων επεμβάσεων στο υπάρχον συγκρότημα, οι οποίες θα ικανοποιούν τις ανάγκες της νέας χρήσης, ενώ παράλληλα θα στοχεύουν στην ανάδειξη των σωζόμενων στοιχείων του και στο σεβασμό της ταυτότητάς του. Επιπροσθέτως, με αφορμή την ερευνητική μας εργασία, που αφορά στη σχέση κτιρίου και φύσης, αναγνωρίζουμε τις ευεργετικές ιδιότητες του φυσικού στοιχείου, στις οποίες περιλαμβάνεται το εὖ ζῆν και η ψυχική ευημερία. Για την απολαβή αυτών των ωφελειών εντάσσεται στο συγκρότημα η φύτευση με διάφορους τρόπους ώστε να επιτευχθεί η σχέση ανθρώπου και φύσης στο οικιστικό περιβάλλον. Τέλος δίνεται έμφαση στην εσωτερική διαμόρφωση λόγω των ιδιαιτεροτήτων του συγκροτήματος με σκοπό την δημιουργία ενός συλλογικού τρόπου κατοίκησης, που συμβάλλει στην ψυχική ενδυνάμωση των φιλοξενούμενων.

description: Helicity and αeffect driven by the nonaxisymmetric Tayler instability of toroidal magnetic fields in stellar radiation zones are computed. In the linear approximation a purely toroidal field always excites pairs of modes with identical growth rates but with opposite helicity so that the net helicity vanishes. If the magnetic background field has a helical structure by an extra (weak) poloidal component then one of the modes dominates producing a net kinetic helicity anticorrelated to the current helicity of the background field. The mean electromotive force is computed with the result that the αeffect by the most rapidly growing mode has the same sign as the current helicity of the background field. The αeffect is found as too small to drive an α^{2} dynamo but the excitation conditions for an αΩdynamo can be fulfilled for weak poloidal fields. Moreover, if the dynamo produces its own αeffect by the magnetic instability then problems with its sign do not arise. For all cases, however, the αeffect shows an extremely strong concentration to the poles so that a possible αΩdynamo might only work at the polar regions. Hence, the results of our linear theory lead to a new topological problem for the existence of large-scale dynamos in stellar radiation zones on the basis of the current-driven instability of toroidal fields.

Stories of mid-life career women with cancer: constructing moral identities in everyday talk

description: Bibliography: p. 89-94
description: This thesis reports the results of a study of stories told by mid-life career women with cancer in Calgary, 2003. An interpretivist approach is used to increase understanding about the role of communication in the social construction of survival. This research focuses on the socially constructed self displayed in dialogic communication. Using narrative methodology and drawing on a corpus of 6 patient-to-patient interviews, this paper demonstrates that: (a) interpersonal communication in narrative forms constitute self identity, and (b) storytellers actively construct moral identities following cancer experience. Drawing on aspects of narrative identity advocated by Ricouer (1984 & 1992) and moral identity advocated by Gergen (1998) I illustrate how narrative methodology may be applied to examine how people deal with cancer by telling stories. This research reveals that post-modem narratives link the mind, the self, and society and enable people to deal with cancer by constructing moral identities for the self.
Bursting Activity in a High-Mass Star-Forming Region G33.64-0.21 Observed with the 6.7 GHz Methanol Maser

description: We report the detection of bursts of 6.7 GHz methanol maser emission in a high-mass star-forming region, G33.64-0.21. One of the spectral components of the maser in this source changed its flux density by 7 times that of the previous day, and it decayed with a timescale of 5 days. The burst occurred repeatedly in the spectral component, and no other components showed such variability. A VLBI observation with the Japanese VLBI Network (JVN) showed that the burst location was at the southwest edge of a spatial distribution, and the bursting phenomenon occurred in a region much smaller than 70 AU. We suggest an impulsive energy release like a stellar flare as a possible mechanism for the burst. These results imply that 6.7 GHz methanol masers could be a useful new probe for studying bursting activity in the process of star formation of high-mass YSOs with a high-resolution of AU scale.

description: We summarize our work on a consistency condition for inflation in two-field cosmological models, in the regime of rapid turn and third-order slow roll. To ensure a sustained inflationary period of this type, one needs to satisfy a certain relation between the scalar potential and the scalar field-space metric. We explain the derivation of this condition. Furthermore, we argue that, generically, the rapid-turn phase tends to be short-lived.

Interactions between brown-dwarf binaries and Sun-like stars

description: Several mechanisms have been proposed for the formation of brown dwarfs, but there is as yet no consensus as to which -- if any -- are operative in nature. Any theory of brown dwarf formation must explain the observed statistics of brown dwarfs. These statistics are limited by selection effects, but they are becoming increasingly discriminating. In particular, it appears (a) that brown dwarfs that are secondaries to Sun-like stars tend to be on wide orbits, $a\ga 100\,{\rm AU}$ (the Brown Dwarf Desert), and (b) that these brown dwarfs have a significantly higher chance of being in a close ($a\la 10\,{\rm AU}$) binary system with another brown dwarf than do brown dwarfs in the field. This then raises the issue of whether these brown dwarfs have formed {\it in situ}, i.e. by fragmentation of a circumstellar disc; or have formed elsewhere and subsequently been captured. We present numerical simulations of the purely gravitational interaction between a close brown-dwarf binary and a Sun-like star. These simulations demonstrate that such interactions have a negligible chance ($<0.001$) of leading to the close brown-dwarf binary being captured by the Sun-like star. Making the interactions dissipative by invoking the hydrodynamic effects of attendant discs might alter this conclusion. However, in order to explain the above statistics, this dissipation would have to favour the capture of brown-dwarf binaries over single brown-dwarfs, and we present arguments why this is unlikely. The simplest inference is that most brown-dwarf binaries -- and therefore possibly also most single brown dwarfs -- form by fragmentation of circumstellar discs around Sun-like protostars, with some of them subsequently being ejected into the field.

description: In a background of a very strong magnetic field a quantum vacuum may turn into a new phase characterized by anisotropic electromagnetic superconductivity. The phase transition should take place at a critical magnetic field of the hadronic strength (B_c \approx 10^{16} Tesla or eB_c \approx 0.6 GeV^2). The transition occurs due to an interplay between electromagnetic and strong interactions: virtual quark-antiquark pairs popup from the vacuum and create -- due to the presence of the intense magnetic field -- electrically charged and electrically neutral spin-one condensates with quantum numbers of ρmesons. The ground state of the new phase is a complicated honeycomblike superposition of superconductor and superfluid vortex lattices surrounded by overlapping charged and neutral condensates. In this talk we discuss similarities and differences between the superconducting state of vacuum and conventional superconductivity, and between the magnetic-field-induced vacuum superconductivity and electric-field-induced Schwinger pair production.
