description: We derive a general effective many-body theory for bosonic polar molecules in strong interaction regime, which cannot be correctly described by previous theories within the first Born approximation. The effective Hamiltonian has additional interaction terms, which surprisingly reduces the anisotropic features of dipolar interaction near the shape resonance regime. In the 2D system with dipole moment perpendicular to the plane, we find that the phonon dispersion scales as $\sqrt{|\bfp|}$ in the low momentum ($\bfp$) limit, showing the same low energy properties as a 2D charged Bose gas with Coulomb ($1/r$) interactions.

Identified problems, preferred helpers, and helper qualities : a cross-cultural comparative study of perceptions
Creators: name: Paterson, David William Gilbert
Publisher: name: University of British Columbia
Year: 2010

description: This study examines two groups, Native and Non-Native Canadians, in terms of three research questions: (a) what do they identify as a problem or concern, (b) who do they seek out for assistance, and (c) what are the preferred qualities of the helper. The sample group was comprised of 255 subjects aged 13-15, and 108 subjects aged 18-20 from Prince Rupert, British Columbia. Native subjects represented 25% of this sample group. Though Native and Non-Native respondents identified similar problems, differences were noted in the selection of helper and preferred qualities of a helper. Native respondents preferred helpers within the family and valued different helper qualities than their Non-Native counterparts. Implications of this study are discussed with respect to, (a) contributing to existing literature in cross-cultural counselling, (b) assisting practising counsellors by providing information about client expectations and (c) contributing to the development of cross-cultural counselling education programs.

description: Ce mémoire de Master en enseignement secondaire II traite des rectifications orthographiques des règles du participe passé et de l’opinion des enseignants à ce sujet, notamment concernant l’enseignement du français à l’école professionnelle. Par l’analyse des propositions passées et actuelles de modification des règles d’accord du participe passé, ce travail propose de s’interroger sur la pertinence de ces rectifications. Sont-elles souhaitables à l’enseignement et à l’apprentissage du français ? Comportent-elles certains risques ? Et quel est le point de vue des enseignants à ce sujet ? Dans un premier temps, ce travail présente les différentes pistes de rectification des règles du participe passé – qui ont été ou sont envisagées – au travers de l’analyse des textes officiels et d’une revue de la littérature scientifique, ainsi que d’un rapide tour d’horizon des articles de presse autour des nouvelles dispositions prévues pour 2023, afin de voir où se situe le débat dans l’opinion publique actuelle. Dans un second temps, afin d’étudier le positionnement des enseignants à ce sujet, une enquête de terrain a été menée auprès des enseignants de français de l’École professionnelle artisanale et commerciale de Bulle (EPAC), en août 2021. Ce travail présente le cadre méthodologique, le profil des participants, ainsi que l’analyse des huit entretiens qualitatifs effectués au cours de cette enquête. Le questionnaire pour mener ces entretiens, ainsi qu’une retranscription partielle de l’un d’eux figurent d’ailleurs dans les annexes de ce travail. Enfin, cette recherche se conclue par une synthèse, non seulement des avantages et des inconvénients soulevés par la littérature scientifique au sujet des rectifications de règles orthographiques du participe passé, mais également sur les bénéfices et les risques qu’y voient les enseignants interrogés lors de l’enquête de terrain. La conclusion de ce travail tente ainsi de dégager quelques pistes de réflexion autour de potentielles rectifications futures.
Evaluation of Exchange Interactions of the Spin Doughnut Mo_{75}V_{20}

description: Magnetic properties of the spin doughnut Mo_{75}V_{20}, which is a frustrated magnetic cluster with twenty spins, are studied by using the finite-temperature Lanczos method. Our model Hamiltonian consists of one ten-spin ring and two five-spin rings with nearest-neighbor antiferromagnetic couplings J and J". The five-spin rings are coupled to the ten-spin ring by an antiferromagnetic exchange interaction J' so as to form isosceles triangles of one J-bond and two J'-bonds. Fitting the theoretical magnetic susceptibility with the experimental one measured by Muller et al., the exchange parameters are estimated as J=388 K, J'=163 K and J"=81 K. The most interesting feature of this system is that the two five-spin rings behave like two free-spins at low temperatures in despite of J'>J". We also calculate temperature dependence of the specific heat, and find three peaks at T sim J, J" and J'/100.

description: This paper presents multiwavelength imaging and broad-band spectroscopy of the relativistic jets in the two nearby radio galaxies 3C 371 and PKS 2201+044, acquired with Chandra, HST, VLA, and Merlin. Radio polarization images are also available. The two sources stand out as "intermediate'' between FRIs and FRIIs; their cores are classified as BL Lacs, although broad and narrow optical emission lines were detected at times. The multiwavelength images show jet morphologies with the X-ray emission peaking closer to the nucleus than the longer wavelengths. The jets are resolved at all wavelengths in a direction perpendicular to the jet axis. The jets SEDs are consistent with a single spectral component from radio to X-rays, interpreted as synchrotron emission. The SEDs show a progressive softening from the inner to the outer regions of the jet, indicating that the electron break energy moves to lower energies with distance from the core. Overall, the X-ray and multiwavelength properties of the jets of 3C 371 and PKS 2201+044 appear intermediate between those of FRIs and FRIIs.

description: L’enseignement de la grammaire évolue petit à petit en Suisse romande, transportant des conceptions et des approches provenant de différentes périodes d’un passé parfois proche, mais aussi d’un passé très lointain. Elle est perçue par les enseignant·e·s comme une sous-discipline délicate à enseigner, remplie de zones d’ombre ou même de pièges. Les élèves maitrisent les concepts grammaticaux de manière hétérogène et ont recours à des procédures d’identification qui rendent visible cette sédimentation : un mélange de celle que l’on nomme grammaire traditionnelle et de grammaire nouvelle se côtoie dans les classes. Former à une approche orientée vers la grammaire nouvelle est une nécessité et un besoin exprimé par les enseignant·e·s. C’est ce qui a été visé en 2020-2021 dans le canton de Neuchâtel via une intervention de formation continue de nonante minutes proposée à tous les enseignants·e·s de la 3e à la 8e. Elle était caractérisée par un modèle utilisant la vidéo pour préparer l’appropriation des contenus théoriques avant de venir au cours. La formation elle-même, tenue à distance, ciblait l’utilisation du métalangage par l’enseignant·e et les élèves ainsi que le recours aux manipulations syntaxiques pour justifier des analyses grammaticales dans le cadre d’activitésproblèmes en interaction. Nous allons essayer d’observer dans cette recherche si cette formation a produit des effets sur les pratiques enseignantes.
Effects of an oscillating field on pattern formation in a ferromagnetic thin film: Analysis of patterns traveling at a low velocity

description: Magnetic domain patterns under an oscillating field is studied theoretically by using a simple Ising-like model. We propose two ways to investigate the effects of the oscillating field. The first one leads to a model in which rapidly oscillating terms are averaged out, and the model can explain the existence of the maximum amplitude of the field for the appearance of patterns. The second one leads to a model that includes the delay of the response to the field, and the model suggests the existence of a traveling pattern which moves very slowly compared with the time scale of the driving field.

Effective tuning of exciton polarization splitting in coupled quantum dots

description: The polarization splitting of the exciton ground state in two laterally coupled quantum dots under an in-plane electric field is investigated and its effective tuning is designed. It is found that there are significant Stark effect and anticrossing in energy levels. Due to coupling between inter- and intra-dot states, the absolute value of polarization splitting is significantly reduced, and it could be tuned to zero by the electric field for proper inter-dot separations. Our scheme is interesting for the research on the quantum dots-based entangled-photon source.

In the continues limit the system's dynamics is described by the Ginzburg-Landau equation with complex coefficients. Such a system has a new parameter alpha that is responsible for the complexity of the medium and that strongly influences possible regimes of the dynamics. We study different spatial-temporal patterns of the dynamics depending on alpha and show transitions from synchronization of the motion to broad-spectrum oscillations and to chaos.

description: This paper considers the use of a 'combinatorial optimization' technique in the aggregation of environmental benefit values. Combinatorial optimization is used to statistically match population census data to a Contingent Valuation survey. The matched survey and census information is then used to produce regional and national total WTP figures. These figures are then compared to figures derived using more standard approaches to calculating aggregate environment benefit values. The choice of aggregation approach is shown to have a major impact upon estimates of total benefits at a regional level, especially when the target population displays considerable heterogeneity across space.

Interpretations for the X(4160) observed in the double charm production at B factories

description: Belle Collaboration has recently observed a new state, the X(4160), in the process of double charm production $e^+e^-\to J/ψ+X(4160)$ followed by $X(4160)\to D^*\bar{D^*}$. We discuss possible interpretations for the X(4160) based on the NRQCD calculations and the potential model estimates for the charmonium spectrum. We first focus on the D-wave spin-singlet $2^{-+}$ charmonium $^1D_2(2D)$, which is estimated to have a small production rate of about 5% of that for $e^+e^-\to J/ψ+η_c(1S)$, and therefore is incompatible with the observed data for X(4160). We then discuss the possibility that the X(4160) is the known $J^{PC}=1^{--}$ charmonium state $ψ(4160)$, which can be produced via two photon fragmentation, but the production rate is much smaller than observed for $e^+e^-\to J/ψ+X(4160)$. In contrast to above two possibilities, the $η_c(4S)$ assignment is a likely one, which is supported by the observed relatively large production rate and non-observation of $D\bar D$ decay of X(4160), but we have to understand why $η_c(4S)$ has such a low mass, which deserves further studies. The P-wave excited state $χ_{c0}(3P)$ is also an interesting candidate, if the observed broad peak around 3.8-3.9 GeV in the recoil mass of $D\bar D$ against $J/ψ$ in $e^++e^-\to J/ψ+D\bar D$ is due to the $χ_{c0}(2P)$ state. Measurements of production angular distributions will be helpful to distinguish between $η_c(4S)$ and $χ_{c0}(3P)$ assignments. Production mechanisms in nonrelativistic QCD are emphasized.

Implications of a gravitational fixed point at high energies are worked out using Wilson's renormalisation group. We find that relevant cross-sections involving virtual gravitons become finite. Based on gravitational lepton pair production we conclude that the LHC is sensitive to a fundamental Planck scale of up to 6 TeV.

There appear three typical regions due to the balance between Coulomb interaction $U_{\rm ee}$ and phonon-mediated attraction $U_{\rm ph}$. For $U_{\rm ee}>U_{\rm ph}$, we observe the standard Kondo effect concerning spin degree of freedom. Since the Coulomb interaction is effectively reduced as $U_{\rm ee}-U_{\rm ph}$, the Kondo temperature $T_{\rm K}$ is increased when $U_{\rm ph}$ is increased. On the other hand, for $U_{\rm ee}

Coarse-Grained Finite-Temperature Theory for the Condensate in Optical Lattices

Year: 2007
Subjects: subject: Other Condensed Matter (cond-mat.other)
subject: FOS: Physical sciences

description: In this work, we derive a coarse-grained finite-temperature theory for a Bose condensate in a one-dimensional optical lattice, in addition to a confining harmonic trap potential. We start from a two-particle irreducible (2PI) effective action on the Schwinger-Keldysh closed-time contour path. In principle, this action involves all information of equilibrium and non-equilibrium properties of the condensate and noncondensate atoms. By assuming an ansatz for the variational function, i.e., the condensate order parameter in an effective action, we derive a coarse-grained effective action, which describes the dynamics on the length scale much longer than a lattice constant. Using the variational principle, coarse-grained equations of motion for the condensate variables are obtained. These equations include a dissipative term due to collisions between condensate and noncondensate atoms, as well as noncondensate mean-field. To illustrate the usefulness of our formalism, we discuss a Landau instability of the condensate in optical lattices by using the coarse-grained generalized Gross-Pitaevskii hydrodynamics. We found that the collisional damping rate due to collisions between the condensate and noncondensate atoms changes sign when the condensate velocity exceeds a renormalized sound velocity, leading to a Landau instability consistent with the Landau criterion. Our results in this work give an insight into the microscopic origin of the Landau instability.

description: Laura Hackett and Sherralyn Simpson recount how they have developed children's understanding of how science and other disciplines relate. Laura explores 'hands on' science enquiry through epistemic insight pedagogy in an after-school 'science and big questions' club aimed at primary children. The workshop sessions demonstrate how big questions such as 'Why do we need water?' or 'Why is the sky blue?' can be investigated through the lenses of science, religion and the wider humanities. Sherralyn discusses 'You are what you eat- or are you?' a classroom workshop that considers through science enquiry, a smaller science question of 'what happens to food when it enters the body?'. However, there are other disciplines that can help and by applying the Discpline wheel (an epistemic insight pedagogical tool), differing perspectives provide insight into the more complex conceptions of human health and lifestyle and how these are influenced by multiple factors that go beyond science.
Psychological transformation in survivors of terminal cancer
Creators: name: Fairbanks, Wendy
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to understand the meaning of transformation in surviving terminal cancer. An existential-phenomenological approach was used to interview five participants who had lived at least five years beyond the diagnosis of widely metastatic or terminal cancer. Review of the literature which addressed the issue of transformation suggested that life-threatening illness is an opportunity for growth. There are many cross-cultural accounts of transformation, and many studies of survivorship qualities, but little research into the transformation process as it is experienced by cancer survivors. Participants told the story of their recovery from cancer and how it changed their lives. Cochran's (1986) dramaturgical approach provided the model for capturing the meaning of this experience in story form. Each interview lasted from 2½to 5 hours. Interviews were audio-recorded and transcribed. Analysis of the interviews followed Colaizzi's (1978) method. Significant statements were extracted from the protocols, themes were formulated, and a description of the experience was written. Other sources of data were used in addition to interviews. An autobiography and a series of articles were collected from two participants. This written material was analyzed in the same way as the interviews. The experience of the researcher also served as data, and was analyzed through reflective and descriptive methods. Conducting interviews, soliciting written descriptions and including the researcher's experience allowed the data to be more broadly supported. Results of the study were validated by the participants in a second interview. They confirmed that the 38 themes and the common pattern of transformation derived from the five participants accurately reflected their own experience. The results indicated that psychological transformation in survivors of terminal cancer is a spiritual journey. In allowing a life-threatening disease to become an opportunity for personal awareness and growth, people can transform their illness into a spiritual teaching. Serious illness can teach people about the meaning of life., and give their own lives purpose and direction. Through this affirmation of life, and by following their purpose and path, healing can occur. This healing not only moves people toward wholeness, but it holds the potential for transforming and healing the problems of others. This pattern of transformation has practical implications for the nature of support useful for people experiencing a health crisis, and has implications for the designing of effective psychosocial support for cancer patients.

description: Tunnelling of material particles through a classically impenetrable barrier constitutes one of the hallmark effects of quantum physics. When interactions between the particles compete with their mobility through a tunnel junction, intriguing novel dynamical behaviour can arise where particles do not tunnel independently. In single-electron or Bloch transistors, for example, the tunnelling of an electron or Cooper pair can be enabled or suppressed by the presence of a second charge carrier due to Coulomb blockade. Here we report on the first direct and time-resolved observation of correlated tunnelling of two interacting atoms through a barrier in a double well potential. We show that for weak interactions between the atoms and dominating tunnel coupling, individual atoms can tunnel independently, similar to the case in a normal Josephson junction. With strong repulsive interactions present, two atoms located on one side of the barrier cannot separate, but are observed to tunnel together as a pair in a second order co-tunnelling process. By recording both the atom position and phase coherence over time, we fully characterize the tunnelling process for a single atom as well as the correlated dynamics of a pair of atoms for weak and strong interactions. In addition, we identify a conditional tunnelling regime, where a single atom can only tunnel in the presence of a second particle, acting as a single atom switch. Our work constitutes the first direct observation of second order tunnelling events with ultracold atoms, which are the dominating dynamical effect in the strongly interacting regime. Similar second-order processes form the basis of superexchange interactions between atoms on neighbouring lattice sites of a periodic potential, a central component of quantum magnetism.

description: Ce travail de mémoire est réalisé en vue de l’obtention de la Maîtrise universitaire en éducation précoce spécialisée. Il traite la thématique du partenariat avec la famille, principe qui est devenu incontournable dans les programmes d’intervention précoce spécialisée. Plus précisément, il aborde le sujet de la réunion de réseau, considérée comme une occasion concrète pour favoriser ce partenariat et engendrer des bénéfices tant pour l’enfant à besoins éducatifs particuliers que pour sa famille. Par le biais d’entretiens semi-directifs réalisés avec neuf parents d’enfants à besoins éducatifs particuliers fréquentant une structure préscolaire inclusive tessinoise, le but de la recherche est de mieux comprendre le vécu parental lors de ces rencontres de réseau. L’analyse des données finale met en évidence plusieurs considérations. Premièrement, cette recherche confirme qu’une évolution des pratiques professionnelles vers un plus grand partenariat avec les familles est en train de s’affirmer. Elle relève aussi qu’il faudra encore du temps pour que certaines attitudes et certaines pratiques, profondément ancrées chez les professionnels mais également chez les parents, puissent pleinement se transformer. Deuxièmement, les résultats montrent l’importance d’inclure les parents dès le processus d’élaboration du projet d’intervention afin d’instaurer des relations de pouvoir partagé visant leur empowerment. Troisièmement, les pratiques d’aide centrées sur la famille, à savoir les pratiques relationnelles et participatives, s’avèrent être des approches concrètes et efficaces pour viser un partenariat de qualité. Finalement, le travail propose des pistes pratiques pour les professionnels travaillant dans le domaine de l’éducation précoce spécialisée, afin de soutenir l’instauration d’une relation partenariale avec la famille et encourager ainsi sa participation active à la rencontre de réseau.
Controlling passively-quenched single photon detectors by bright light

description: Single photon detectors based on passively-quenched avalanche photodiodes can be temporarily blinded by relatively bright light, of intensity less than a nanowatt. I describe a bright-light regime suitable for attacking a quantum key distribution system containing such detectors. In this regime, all single photon detectors in the receiver Bob are uniformly blinded by continuous illumination coming from the eavesdropper Eve. When Eve needs a certain detector in Bob to produce a click, she modifies polarization (or other parameter used to encode quantum states) of the light she sends to Bob such that the target detector stops receiving light while the other detector(s) continue to be illuminated. The target detector regains single photon sensitivity and, when Eve modifies the polarization again, produces a single click. Thus, Eve has full control of Bob and can do a successful intercept-resend attack. To check the feasibility of the attack, 3 different models of passively-quenched detectors have been tested. In the experiment, I have simulated the intensity diagrams the detectors would receive in a real quantum key distribution system under attack. Control parameters and side effects are considered. It appears that the attack could be practically possible.

description: A game-theoretic framework is used to study the effect of constellation size on the energy efficiency of wireless networks for M-QAM modulation. A non-cooperative game is proposed in which each user seeks to choose its transmit power (and possibly transmit symbol rate) as well as the constellation size in order to maximize its own utility while satisfying its delay quality-of-service (QoS) constraint. The utility function used here measures the number of reliable bits transmitted per joule of energy consumed, and is particularly suitable for energy-constrained networks. The best-response strategies and Nash equilibrium solution for the proposed game are derived. It is shown that in order to maximize its utility (in bits per joule), a user must choose the lowest constellation size that can accommodate the user's delay constraint. Using this framework, the tradeoffs among energy efficiency, delay, throughput and constellation size are also studied and quantified. The effect of trellis-coded modulation on energy efficiency is also discussed.

description: We provide a characterization of the spectral minimum for a random Schrödinger operator of the form $H=-Δ+ \sum_{i \in \Z^d}q(x-i-ω_i)$ in $L^2(\R^d)$, where the single site potential $q$ is reflection symmetric, compactly supported in the unit cube centered at 0, and the displacement parameters $ω_i$ are restricted so that adjacent single site potentials do not overlap. In particular, we show that a minimizing configuration of the displacements is given by a periodic pattern of densest possible $2^d$-clusters of single site potentials. The main tool to prove this is a quite general phenomenon in the spectral theory of Neumann problems, which we dub ``bubbles tend to the boundary.'' How should a given compactly supported potential be placed into a bounded domain so as to minimize or maximize the first Neumann eigenvalue of the Schrödinger operator on this domain? For square or rectangular domains and reflection symmetric potentials, we show that the first Neumann eigenvalue is minimized when the potential sits in one of the corners of the domain and is maximized when it sits in the center of the domain. With different methods we also show a corresponding result for smooth strictly convex domains.

title: Cohabitation in Ireland: evidence from survey data
Creators: name: O'Donoghue, Cathal
Publisher: name: National University of Ireland, Galway
Year: 2005
Subjects: subject: Economics

description: Cohabitation has grown strongly in Ireland over the last decade. We use large-scale surveys to characterise its extent and nature. We find it has almost tripled in incidence between 1994 and 2002. It is associated with being young, urban and in the labour market. Most cohabitations are short, and a high proportion end in marriage. Over 40 percent of new marriages are now preceded by cohabitation, making it close to a majority practice rather than the deviant behaviour it would have been a generation ago. In this respect it seems to be developing as an adaptation of marriage rather than an alternative to it.
Energy-Efficient Resource Allocation in Wireless Networks with Quality-of-Service Constraints

description: A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks. In the proposed game, each user seeks to choose its transmit power and rate in a distributed manner in order to maximize its own utility while satisfying its QoS requirements. The user's QoS constraints are specified in terms of the average source rate and an upper bound on the average delay where the delay includes both transmission and queuing delays. The utility function considered here measures energy efficiency and is particularly suitable for wireless networks with energy constraints. The Nash equilibrium solution for the proposed non-cooperative game is derived and a closed-form expression for the utility achieved at equilibrium is obtained. It is shown that the QoS requirements of a user translate into a "size" for the user which is an indication of the amount of network resources consumed by the user. Using this competitive multiuser framework, the tradeoffs among throughput, delay, network capacity and energy efficiency are studied. In addition, analytical expressions are given for users' delay profiles and the delay performance of the users at Nash equilibrium is quantified.

Tidal Debris posing as Dark Galaxies

description: Debris sent into the intergalactic medium during tidal collisions can tell us about several fundamental properties of galaxies, in particular their missing mass, both in the form of cosmological Dark Matter and so-called Lost Baryons. High velocity encounters, which are common in clusters of galaxies, are able to produce faint tidal debris that may appear as star-less, free floating HI clouds. These may be mistaken for Dark Galaxies, a putative class of gaseous, dark matter dominated, objects which for some reason never managed to form stars. VirgoHI21 is by far the most spectacular and most discussed Dark Galaxy candidate so far detected in HI surveys. We show here that it is most likely made out of material expelled 750 Myr ago from the nearby spiral galaxy NGC 4254 during its fly--by at about 1000 km/s by a massive intruder. Our numerical model of the collision is able to reproduce the main characteristics of the system: in particular the absence of stars, and its prominent velocity gradient. Originally attributed to the gas being in rotation within a massive dark matter halo, we find it instead to be consistent with a combination of simple streaming motion plus projection effects (Duc & Bournaud, 2007). We discuss several ways to identify a tidal origin in a Dark Galaxy candidate and illustrate the method using another HI system in Virgo, VCC 2062, which is most likely a Tidal Dwarf Galaxy (Duc et al., 2007). Now, whereas tidal debris should not contain any dark matter from the halo of their parent galaxies, it may exhibit missing mass in the form of dark baryons, unaccounted for by classical observations, as recently found in the collisional ring of NGC 5291 (Bournaud et al., 2007) and probably in the TDG VCC 2062. These "Lost Baryons" must originally have been located in the disks of their parent galaxies.
