description: We obtain the large deviation functional of a density profile for the asymmetric exclusion process of L sites with open boundary conditions when the asymmetry scales like 1/L. We recover as limiting cases the expressions derived recently for the symmetric (SSEP) and the asymmetric (ASEP) cases. In the ASEP limit, the non linear differential equation one needs to solve can be analysed by a method which resembles the WKB method.
title: Computers, talk and learning : using computers to help coach reasoning through talk across the curriculum
Creators: name: Wegerif, Rupert
Publisher: name: The Open University
Year: 1995

description: The main theme of this thesis is the role of computers as a support for reasoning through talk in the classroom. A second, closely linked, theme is the role of reasoning through talk in general intellectual development.

In the first part of the thesis the two areas of the teaching of thinking skills and the use of computers as a support for cooperative work in classrooms are explored through critical reviews of the literature and through two empirical studies. The findings of this exploratory research lead to the development of a theoretical framework for the use of computers in classrooms. This theoretical framework consists of the characterisation of a type of talk that is effective in promoting general intellectual development, a model of the structure of educational activities in which groups of children work with computers and a set of principles for the design of software to support reasoned discussion.

In the second part of the thesis the theoretical framework is explored and tested through the development and implementation of an intervention programme. A new methodology is developed to evaluate this intervention programme integrating a quasi-experimental method with both qualitative discourse analysis and computer-based discourse analysis. The findings of the evaluation support four key hypotheses which emerge from the theoretical framework. First, that there is a link between the coaching of reasoning through talk and performance on tests of general reasoning ability. Second, that the quality of computer-supported collaborative learning can be enhanced through the off-computer coaching of exploratory talk. Third, that group work at computers can in turn be used effectively to extend an educational programme designed to coach exploratory talk across the curriculum. Fourth, that computer-based collaborative learning can - be used to integrate active peer-learning with directed teaching. These findings have significant implications for educational theory and practice.

description: We present MERLIN observations of OH maser and radio continuum emission from the Ultra Luminous IR Galaxy Markarian 231. The 1665- and 1667-MHz transitions have a combined velocity extent of 720 km/s and show a similar position-velocity structure including a gradient of 1.7 km/s/pc from NW to SE along the 420-pc major axis, steeper in the inner few tens of pc. The maser distribution is modelled as a torus rotating about an axis inclined at ~45deg. We estimate the enclosed mass density to be 320(90) Msun in a flattened distribution, including a central unresolved mass of =8E+06 Msun. All the maser emission is projected against a region with a radio continuum brightness temperature >/=1E+05 K, giving a maser gain of =2.2. The 1667:1665-MHz line ratio is close to the LTE ratio of 1.8 consistent with radiatively pumped, unsaturated masers. The size of individual masing regions is in the range 0.25-4 pc with a covering factor close to unity. There are no very bright compact masers, in contrast to galaxies such as the Seyfert 2 Markarian 273 where the masing torus is viewed nearer edge-on. The comparatively modest maser amplification seen from Markarian 231 is consistent with its classification as a Seyfert 1. Most of the radio continuum emission on 50-500 pc scales is probably of starburst origin but the compact peak is 0.4 per cent polarized by a magnetic field running north-south, similar to the jet direction on these scales. There is no close correlation between maser and continuum intensity. Comparisons with other data show that the jet changes direction close the nucleus and suggest that the sub-kpc disc hosting the masers and starburst activity is severely warped.

title: Craft knowledge in medicine : an interpretation of teaching and learning in apprenticeship
Creators: name: Macdonald, Morag M.
Publisher: name: The Open University
Year: 1998

description: The diagnosis and management of patients requires professional know-how or medical craft knowledge. To explain how this knowledge is acquired, this research asked 'How do medical experts pass on their craft?' Other questions arose through successive data collections and progressive focusing on what medical experts did well in their work and teaching. The programme comprised: pilot interviews with three expert physicians; a case study in a hospital medical unit; and paired consultant/SHO interviews. Participant observation, interviews, and expert-novice comparisons explored clinical work, teaching, and learning in apprenticeship.

Data analysis of participants' responses and ward round discussions allowed identified categories to cluster within three inter-related constructs instrumental to the acquisition of medical knowledge: gaining experience in the experiential process of clinical practice (1); and the products of experience which manifest as experts' clinical expertise (2) and teaching/learning expertise (3). These constructs can be located within a model of apprenticeship based on Spady's (1973) analysis of authority in effective teaching containing two frames of reference: the social, 'traditional-legal'; and the individual, 'expert-charismatic'. The medical apprenticeship is associated with similar perspectives: the 'traditional-experiential' represents the professional process of learning through patient care with its infrastructure of clinical methods in presentation, discourse, and commentary; and the 'expert-charismatic' represents clinical and teaching expertise coupled with vocational enthusiasm.

Experienced experts synthesised two repertoires of knowledge and skills derived from the craft knowledge of medicine and pedagogy, respectively. Both crafts are required for effective clinical education. While apprenticeship accommodates a range of teaching/learning experiences, in postgraduate education experts pass on knowledge through the deliberate engagement of junior doctors in diagnosis and management. The skills involved in this process were largely unrecognised by most senior and junior doctors and were not perceived as 'clinical teaching' although learning was structured through service-based work.

description: It has been recently realized that, in the case of polynomial potentials, the exact WKB method can be reformulated in terms of a system of TBA equations. In this paper we study this method in various examples. We develop a graphical procedure due to Toledo, which provides a fast and simple way to study the wall-crossing behavior of the TBA equations. When complemented with exact quantization conditions, the TBA equations can be used to solve spectral problems exactly in Quantum Mechanics. We compute the quantum corrections to the all-order WKB periods in many examples, as well as the exact spectrum for many potentials. In particular, we show how this method can be used to determine resonances in unbounded potentials.

description: We explore higher order dynamical effects in the transport through a two-dimensional nanoscale electron system embedded in a three-dimensional far-infrared photon cavity. The nanoscale system is considered to be a short quantum wire with a single circular quantum dot defined in a GaAs heterostructure. The whole system, the external leads and the central system are placed in a constant perpendicular magnetic field. The Coulomb interaction of the electrons, the para- and diamagnetic electron-photon interactions are all treated by a numerically exact diagonalization using step-wise truncations of the appropriate many-body Fock spaces. We focus on the difference in transport properties between a description within an electric dipole approximation and a description including all higher order terms in a single photon mode model. We find small effects mostly caused by an electrical quadrupole and a magnetic dipole terms that depend strongly on the polarization of the cavity field with respect to the transport direction and the photon energy. When the polarization is aligned along the transport direction we find indications of a weak self-induction that we analyze and compare to the classical counterpart, and the self-energy contribution of high-order interaction terms to the states the electrons cascade through on their way through the system. Like expected the electron-photon interaction is well described in the dipole approximation when it is augmented by the lowest order diamagnetic part for a nanoscale system in a cavity in an external magnetic field.

description: We study the conditions for a double quantum dot system to work as a reliable electron spin entangler, and the efficiency of a beam splitter as a detector for the resulting entangled electron pairs. In particular, we focus on the relative strengths of the tunneling matrix elements, the applied bias and gate voltage, the necessity of time-dependent input/output barriers, and the consequence of considering wavepacket states for the electrons as they leave the double dot to enter the beam splitter. We show that a double quantum dot turnstile is, in principle, an efficient electron spin entangler or entanglement filter because of the exchange coupling between the dots and the tunable input/output potential barriers, provided certain conditions are satisfied in the experimental set-up.

description: Weaning is a challenging period for piglets associated with reduced feed intake, impairment of gut integrity, and diarrhea. Previous studies demonstrate that supplementation with single functional amino acids (AA) promote piglets’ performance due to the improvement of intestinal health. Thus, we hypothesized that a combination of functional AA provided beyond the postulated requirement for growth could facilitate the weaning transition. Ninety piglets, initially stressed after weaning by 100 min overland transport, received a control diet or the same diet supplemented with a low-dosed (0.3%) mixture of AA (AAB-1: L-arginine, L-leucine, L-valine, L-isoleucine, L-cystine; AAB-2: L-arginine, L-leucine, L-valine, L-isoleucine, L-cystine, and L-tryptophan) for 28 days. Fecal consistency was ranked daily, growth performance was assessed weekly. On days 1 and 14 of the trial, blood samples were collected from a subset of 10 piglets per group to assess concentrations of insulin-like growth factor 1. After 28 days of feeding, tissues were obtained from the same piglets to analyze gut morphology and relative mRNA expression of genes related to gut function. Even if the stress response as indicated by rectal temperature was not different between the groups, pigs supplemented with AAB-2 showed firmer feces after weaning and less days with diarrhea compared to control. Furthermore, the jejunal expression of the MUC-2 gene was reduced (P < 0.05) in group AAB-2. Both AA mixtures increased crypt depth in the duodenum. Collectively, the given results indicate that 0.3% extra AA supplementation might alleviate postweaning diarrhea but did not alter growth performance of weanling piglets.

description: The one-dimensional Hubbard model is investigated by means of two different cluster schemes suited to introduce short-range spatial correlations beyond the single-site Dynamical Mean-Field Theory, namely the Cluster-Dynamical Mean-Field Theory and its periodized version. It is shown that both cluster schemes are able to describe with extreme accuracy the evolution of the density as a function of the chemical potential from the Mott insulator to the metallic state. Using exact diagonalization to solve the cluster impurity model, we discuss the role of the truncation of the Hilbert space of the bath, and propose an algorithm that gives higher weights to the low frequency hybridization matrix elements and improves the speed of the convergence of the algorithm.

description: A self-consistent large $N_c$ approach is developed for the collective quantization of SU(3) flavor hedgehog solitons, such as the Skyrmion. The key to this analysis is the determination of all of the zero modes associated with small fluctuations around the hedgehog. These are used in the conventional way to construct collective coordinates. This approach differs from previous work in that it does not implicitly assume that each static zero mode is associated with a dynamical zero mode. It is demonstrated explicitly in the context of the Skyrmion that there are fewer dynamical zero modes than static ones due to the Witten-Wess-Zumino term in the action. Group-theoretic methods are employed to identify the physical states resulting from canonical quantization of the collectively rotating soliton. The collective states fall into representations of SU(3) flavor labeled by $(p,q)$ and are given by $(2J, \frac{Nc}{2} -J)$ where $J={1/2},{3/2},... $ is the spin of the collective state. States with strangeness $S > 0$ do not arise as collective states from this procedure; thus the $θ^{+}$ (pentaquark) resonance does not arise as a collective excitation in models of this type.

description: We consider the (unoriented) long-range percolation on Z^d in dimensions d\ge1, where distinct sites x,y\in Z^d get connected with probability p_{xy}\in[0,1]. Assuming p_{xy}=|x-y|^{-s+o(1)} as |x-y|\to\infty, where s>0 and |\cdot| is a norm distance on Z^d, and supposing that the resulting random graph contains an infinite connected component C_{\infty}, we let D(x,y) be the graph distance between x and y measured on C_{\infty}. Our main result is that, for s\in(d,2d), D(x,y)=(\log|x-y|)^{Δ+o(1)},\qquad x,y\in C_{\infty}, |x-y|\to\infty, where Δ^{-1} is the binary logarithm of 2d/s and o(1) is a quantity tending to zero in probability as |x-y|\to\infty. Besides its interest for general percolation theory, this result sheds some light on a question that has recently surfaced in the context of ``small-world'' phenomena. As part of the proof we also establish tight bounds on the probability that the largest connected component in a finite box contains a positive fraction of all sites in the box.

description: Studies on photoreceptors provide a wealth of information on cofactor and protein dynamics on the microsecond to seconds time-scale. Up to now, ultrafast dynamics addresses mainly the cofactor or chromophore, but ultrafast protein dynamics are poorly understood. Increasing evidence show that protein responses can occur even faster than the cofactor dynamics. The causal reason for the ultrafast protein response cannot be explained by the localized cofactor excitation or its excited-state decay, alone. We propose a Coulomb interaction mechanism started by a shock wave and stabilized by a dipole moment change at least partially responsible for coherent oscillations in proteins, protonation changes, water dislocations, and protein changes prior to and beyond chromophore’s excited-state decay. Photoexcitation changes the electron density distribution of the chromophore within a few femtoseconds: The Coulomb shock wave affects polar groups, hydrogen bonds, and protein bound water molecules. The process occurs on a time-scale even faster than excited-state decay of the chromophore. We discuss studies on selected photoreceptors in light of this mechanism and its impact on a detailed understanding of protein dynamics.
Observation of extended scattering continua characteristic of spin fractionalization in the 2D frustrated quantum magnet Cs2CuCl4 by neutron scattering

description: The magnetic excitations of the quasi-2D spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice Cs2CuCl4 are explored throughout the 2D Brillouin zone using inelastic neutron scattering. In the spin liquid phase above the transition to magnetic order extended excitation continua are observed, characteristic of fractionalization of S=1 spin waves into pairs of deconfined S=1/2 spinons and the hallmark of a resonating-valence-bond (RVB) state. The weak inter-layer couplings stabilize incommensurate spiral order at low temperatures and in this phase sharp magnons carrying a small part of the total scattering weight are observed at low energies below the continuum lower boundary. Linear spin-wave theory including one- and two-magnon processes can describe the sharp magnon excitation, but not the dominant continuum scattering, which instead is well described by a parameterized two-spinon cross-section. Those results suggest a cross-over in the nature of excitations from S=1 spin waves at low energies to S=1/2 spinons at medium to high energies, which could be understood if Cs2CuCl4 was in the close proximity of a transition between a fractional spin liquid and a magnetically-ordered phase.

description: We focus on quantum systems that can be effectively described as a localized spin-$s$ particle subject to a static magnetic field coplanar to a coexisting elliptically rotating time-periodic field. Depending on the values taken on by the static and rotating components, the total magnetic field shows two regimes with different topological properties. Along the boundary that separates these two regimes, the total magnetic field vanishes periodically in time and the system dynamics becomes highly nonadiabatic. We derive a relation between two time-averaged quantities of the system which is linked to the topology of the applied magnetic field. Based on this finding, we propose a measurable quantity that has the ability to indicate the topology of the total magnetic field without knowing a priori the value of the static component. We also propose a possible implementation of our approach by a trapped-ion quantum system. The results presented here are independent of the initial state of the system. In particular, when the system is initialized in a Floquet state, we find some interesting properties of the quasienergy spectrum which are linked to the topological change of the total magnetic field. Throughout the paper, the theoretical results are illustrated with numerical simulations for the case of a two-level quantum system.

description: In this paper, we present an in-depth analysis of a voltage-controlled oscillator (VCO)-based sensing method for electron spin resonance (ESR) spectroscopy, which greatly simplifies the experimental setup compared to conventional detection schemes. In contrast to our previous oscillator-based ESR detectors, where the ESR signal was encoded in the oscillation frequency, in the amplitude-sensitive method, the ESR signal is sensed as a change of the oscillation amplitude of the VCO. Therefore, using VCO architecture with a built-in amplitude demodulation scheme, the experimental setup reduces to a single permanent magnet in combination with a few inexpensive electronic components. We present a theoretical analysis of the achievable limit of detection, which uses perturbation-theory-based VCO modeling for the signal and applies a stochastic averaging approach to obtain a closed-form expression for the noise floor. Additionally, the paper also introduces a numerical model suitable for simulating oscillator-based ESR experiments in a conventional circuit simulator environment. This model can be used to optimize sensor performance early on in the design phase. Finally, all presented models are verified against measured results from a prototype VCO operating at 14 GHz inside a 0.5 T magnetic field.

description: We exploit the pumped spin-current and current noise spectra under equilibrium condition in a single quantum dot connected to two normal leads, as an electrical scheme for detection of the electron spin resonance (ESR) and decoherence. We propose spin-resolved quantum rate equations with correlation functions in Laplace-space for the analytical derivation of the zero-frequency atuo- and cross-shot noise spectra of charge- and spin-current. Our results show that in the strong Coulomb blockade regime, ESR-induced spin flip generates a finite spin-current and the quantum partition noises in the absence of net charge transport. Moreover, spin shot noise is closely related to the magnetic Rabi frequency and decoherence and would be a sensitive tool to measure them.

description: Human papillomavirus (HPV) detection is used for screening of cervical cancer and genotype-specific persistence has shown to be mandatory for dysplasia development. Aim of this study was to evaluate the clinical performance of HPV DNA Array for cervical intraepithelial neoplasia 2+ (CIN2+) lesion detection. HPV DNA Array is a polymerase chain reaction-based assay that targets E1 sequences of 29 HPV types (6, 11, 16, 18, 26, 31, 33, 35, 39, 40, 42, 44, 45, 51, 52, 53, 54, 56, 58, 59, 66, 67, 68, 69, 70, 73, 82, 85, and 97). The clinical evaluation was performed against the reference assay, BS-GP5+/6+ multiplex genotyping (MPG)-Luminex, with 600 cervical smear samples of a referral population. HPV DNA Array detected CIN2+ lesions with a sensitivity of 90.2%, identical to that of MPG-Luminex. Detection of CIN3+ lesions was with a sensitivity of 90.3%, as compared with 88.7% of MPG-Luminex. It demonstrated very good agreement for HPV detection, irrespective of type, of 91.5% (kappa = 0.832). HPV DNA Array is a simple and robust assay, with a short protocol of 4 hours hands-on time and automated readout by ELISpot AiDot software. It permits testing of up to 96 samples in one run and may be considered for use in organized screening programs and low resource settings.
Hippocratic Diagnosis, Solomonic Therapy, Roman Amulets: Epilepsy, Exorcism, and the Diffusion of a Jewish Tradition in the Roman World

description: Two contrasting portraits of exorcism in the Roman period for patients with symptoms consistent with epilepsy, drawn by Josephus (A.J. 8.45–47) and Lucian (Philops. §16), illustrate a substantial albeit contested diffusion of that ancient technique from the Jewish tradition to a wider Mediterranean public. The process is reflected in a similarly complex traditional background and textual composition of a group of inscribed Greek amulets for epilepsy. A sidelight on attitudes towards the practice of exorcism, on its way to wider popularity, and the conception of epilepsy is cast by these amulets, which have not yet been studied as a group. Their texts witness the application of precise Greek medical terminology, yet to an end, and in a compositional company, that authors in the Hippocratic tradition would have rejected. More generally, the artifacts offer a cross-section of amuletic practice and its diversity in the Roman and late ancient periods.
A plan for the future : the legacies of the British Commonwelath Air Training Plan in Canada's prairie provinces
Creators: name: Newell, Allan
Publisher: name: University of British Columbia
Year: 2011

description: The establishment of the British Commonwealth Air Training Plan (BCATP) saw the creation of more than one hundred air training schools across the country. In the West, the wide-open spaces facilitated many of these sites, and a sophisticated network of airfields sprang up across the prairies almost overnight. The substantial and enduring impact of the BCATP's airfields and schools in the Canadian West is curiously overlooked by historians, who (for the most part) often focus on the Plan's overall operation at the expense of its lasting influence. The construction of the BCATP sites prompted extensive modernisation of the existing infrastructure in many of the small communities selected for schools. Moreover, the vast sums of money poured into the region and the tens of thousands of Commonwealth airmen who came to train at the airfields had a significant and long-term cultural and economic impact on the region. Along with improved infrastructure, the BCATP brought a new cosmopolitanism and a strong regional affinity for the Air Force. More importantly, the Plan influenced the perceptions and perceived roles of women in the prairies and has had an enduring effect on the Canadian women's movement. In the postwar years, the demographics of the prairies shifted as thousands of BCATP alumni returned to take-up residence in the region they had trained in, while at the same time Canadian war brides departed to be with their new husbands abroad. Industry was transformed as well, as civil aviation took up the legacy of the BCATP and opened up the North while at the same time establishing air transport connections among the prairie provinces, the rest of the nation and the world--connections which contributed to the rapid urbanization, economic growth and cultural evolution of the region.

description: We calculate the inclusive heavy quark production cross section for proton-nucleus collisions at high energies. We perform calculation in a quasi-classical approximation (McLerran-Venugopalan model) neglecting all low-x evolution effects. The derived expression for the differential cross section can be applied for studying the heavy quark production in the central rapidity region at RHIC.

description: Between 2006 and 2011, in a global context of rising food prices, many countries applied price-isolating policies. Export restrictions were among the measures most frequently applied. However, as countries are not obliged to notify WTO about the imposition of export restrictions, there is not good information about the measures applied. We fill this void by building a comprehensive database on export restrictions applied in the agricultural sector worldwide between 2005 and 2014. We name it the Export Restriction in Agriculture (ERA) database, and we use it to analyze the incidence of export restrictions by country, type of product, type of measure, and time span. Using the ERA database, we assess the effects of export restrictions on agricultural trade and global food prices in the period 2005-2013. To do so, we estimate a disaggregated gravity model of trade where the effects of export restrictions and import tariffs on traded values and volumes allowed us to infer the existence of an effect on prices. Clear evidence of export restrictions affecting world prices is limited to a handful of sectors, and weak evidence suggests that it may exist in some other sectors. We also find weak evidence of an impact of import promoting policies on agricultural prices. These results highlights the idea that export restrictions should be addressed at the multilateral level, but negotiations on export restrictions should not be disassociated from talks on other price-insulating policies.

description: Host population size, density, immune status, age structure, and contact rates are critical elements of virus epidemiology. Slum populations stand out from other settings and may present differences in the epidemiology of acute viral infections. We collected nasopharyngeal specimens from 282 children aged ≤5 years with acute respiratory tract infection (ARI) during 2005 to 2006 in one of the largest Brazilian slums. We conducted real-time reverse transcription-polymerase chain reaction (RT-PCR) for 16 respiratory viruses, nested RT-PCR-based typing of rhinoviruses (HRVs), and collected clinical symptoms. Viruses were common causes of respiratory disease; with ≥1 virus being detected in 65.2% of patients. We detected 15 different viruses during 1 year with a predominance of HRV (33.0%) and human respiratory syncytial virus (hRSV, 12.1%) infections, and a high rate of viral coinfections (28.3%). We observed seasonality of hRSV, HRV and human coronavirus infections, more severe symptoms in hRSV and influenza virus (FLU) infections and prolonged circulation of seven HRV clusters likely representing distinct serotypes according to genomic sequence distances. Potentially unusual findings included the absence of human metapneumovirus detections and lack of typical FLU seasonal patterns, which may be linked to the population size and density of the slum. Nonetheless, most epidemiological patterns were similar to other studies globally, suggesting surprising similarities of virus-associated ARI across highly diverse settings and a complex impact of population characteristics on respiratory virus epidemiology.

description: Generalized Spatial Modulation (GSM) is being considered for high capacity and energy-efficient networks of the future. However, signal detection due to inter-channel interference among the active antennas is a challenge in GSM systems and is the focus of this letter. Specifically, we explore the feasibility of using deep neural networks (DNN) for signal detection in GSM. In particular, we propose a block DNN (B-DNN) based architecture, where the active antennas and their transmitted constellation symbols are detected by smaller sub-DNNs. After N-ordinary DNN detection, the Euclidean distance-based soft constellation algorithm is implemented. The proposed B-DNN detector achieves a BER performance that is superior to traditional block zero-forcing (B-ZF) and block minimum mean-squared error (B-MMSE) detection schemes and similar to that of classical maximum likelihood (ML) detector. Further, the proposed method requires less computation time and is more accurate than alternative conventional numerical methods.
