Radiative muon capture on carbon, oxygen and calcium
Creators: name: Armstrong, David Stairs
Publisher: name: University of British Columbia
Year: 2010

description: The partial branching ratio for photons of greater than 57 MeV (G[sub >57]) has been measured for radiative muon capture (RMC) on ¹²C, ¹⁶O and ⁴⁰Ca in order to determine the magnitude of the induced pseudoscalar coupling constant g[sub p] of the weak hadronic current. A time projection chamber (TPC) was used as a large solid-angle, medium-resolution pair spectrometer to detect the photons from RMC. The resulting spectra were essentially background-free, allowing a determination of the partial branching ratios to about 10% precision. For ⁴⁰Ca, the partial branching ratio obtained is in good agreement with previous measurements, and yields the value g[sub p]/g[sub a] = 5.7 ± 0.8 when compared with a phenomenological calculation of the nuclear response function and the value g[sub p]/g[sub a] = 4.6 ± 1.8 when compared with a microscopic calculation of the nuclear response function. Both of these results suggest a slight (downward) renormalization of g[sub p]/g[sub a] in ⁴⁰Ca in comparison with the value expected for a free nucleoli. For ¹⁶O, the partial branching ratio obtained in the present experiment is found to disagree strongly with one previous experiment but to agree with the second previous measurement. When compared with a phenomenological calculation of the nuclear response our result yields g[sub p]/g[sub a] = 7.3 ± 0.9, consistent with an un-renormalized value of g[sub p]. The same results compared to a microscopic calculation give the value g[sub p]/g[sub a] = 13.6 [sup +1.6]/[sub -1.9] suggesting a large (upward) renormalization of g[sub p] in the ¹⁶O nucleus. The first precise branching ratio has also been measured for RMC on ¹²C. No calculation of the nuclear response specific to ¹²C is available at present. However, when the present data are compared with a naive extrapolation of Fermi-gas model calculations of the nuclear response for heavier nuclei, the brandling ratio is found to be consistent with an unrenormalized value of g[sub p]. The present work has also provided valuable input, through the investigation of various systematic errors and potential backgrounds, into the design of a detection system for a forthcoming measurement of RMC on hydrogen.

description: The Zero-Range Process, in which particles hop between sites on a lattice under conserving dynamics, is a prototypical model for studying real-space condensation. Within this model the system is critical only at the transition point. Here we consider a non-conserving Zero-Range Process which is shown to exhibit generic critical phases which exist in a range of creation and annihilation parameters. The model also exhibits phases characterised by mesocondensates each of which contains a subextensive number of particles. A detailed phase diagram, delineating the various phases, is derived.

description: No abstracts are to be cited without prior reference to the author.Development towards intensive rearing systems represent new challenges to the aquaculture industry, as ethically acceptable standards for treatment of animals will be required. The increasing activities of the aquaculture industry brings it into view and makes it more open to the critical eye of the public opinion. In land animal husbandry, discussions regarding handling and treatment of animals are part of everyday life. Aquaculture production has, so far, received far less attention. And where animal husbandry have a history reaching thousands of years back, aquaculture is relatively new. This fact represents problems as well as possibilities. The problems are represented by the sparse knowledge about the biological limits and optimal technological solutions. The possibilities lie in the chance of avoiding mistakes. MC)re attention is to be expected, both from governments, consumers and possibly also from animal welfare groups. In future, conflicts regarding the well-being of aquaculture organisms are to be expected.

description: Infiltration of the knee is a common procedure. It is performed differently depending on the practitioner's experience and the availability of ultrasound. Lateral patellar infiltration is the most commonly used. Ultrasound has improved the quality of infiltration.  We describe a simple procedure under ultrasound control that allows us to be in the joint cavity and to avoid injecting extra-articularly or intra-vascularly. We illustrate this procedure with two cases, in the presence and absence of joint effusion.
description: L’infiltration du genou est un acte courant. Elle est réalisée différemment selon l’expérience du praticien et la disponibilité de l’échographie. L’infiltration par voie latéro-patellaire est la plus utilisée. L’échographie a amélioré la qualité des infiltrations.  Nous décrivons une simple procédure sous contrôle échographique permettant d’être dans la cavité articulaire et d'éviter d’injecter en extra articulaire ou intra vasculaire. Nous illustrons cette procédure par deux cas, en présence et en l’absence d’épanchement articulaire.
Quantum repeater protocol in mixed single- and two-mode Tavis-Cummings models

description: In this paper we study the production of entanglement between two atoms which are far from each other. We consider a system including eight two-level atoms (1; 2;... ; 8) such that any atom with its adjacent atom is in atomic Bell state, so that we have four separate pairs of maximally entangled states (i; i + 1) where i = 1; 3; 5; 7. Our purpose is to produce entanglement between the atomic pair (1, 8), while these two distant atoms have no interaction. By performing the interaction between adjacent nonentangled atomic pairs (2, 3) as well as (6, 7), each pair with a two-mode quantized field, the entanglement is produced between atoms (1, 4) and (5, 8), respectively. Finally, by applying an appropriate Bell state measurement (BSM) on atoms (4, 5) or performing an interaction between them with a single-mode field (quantum electrodynamic: QED method), the qubit pair (1; 8) becomes entangled and so the quantum repeater is successfully achieved. This swapped entanglement is then quantified via concurrence measure and the effects of coupling coeficients and detuning on the concurrence and success probability are numerically investigated. The maxima of concurrence and success probability and the corresponding time periods have been decreased by increasing the detuning in asymmetric condition in BSM method. Also, the effects of detuning, initial interaction time and coupling coeficient on the produced entanglement by QED method are considered. Increasing (decreasing) of the detuning (interaction time) has destructive effect on the swapped entanglement in asymmetric condition.

Γι’ αυτόν τον σκοπό, ψηφιοποιήθηκαν σε μορφή Word 316 κείμενα ιταλικής γλώσσας των εξετάσεων ΚΠΓ περιόδων Μαΐου 2015 και Νοεμβρίου 2016 των επιπέδων Β1 και Β2, παραγόμενα από Έλληνες χρήστες. Για την ανάλυση των δεδομένων έγινε χρήση του εργαλείου READ-IT και για την παραγοντική ανάλυση το λογισμικό SPSS.24. Τα αποτελέσματα έδειξαν ότι η διάκριση μεταξύ των δυο επιπέδων γλωσσομάθειας βασίζεται σε στοιχεία γραμματικής και σύνταξης (ορθογραφία, χρήση δευτερευουσών προτάσεων, πολυσύλλαβες λέξεις κτλ.), αλλά και σε άλλους σημαντικούς παράγοντες όπως η συνοχή των λέξεων και προτάσεων, λεξική πυκνότητα, αξιολόγηση εξεταστών, δείκτης READ-IT Globale κ.α. Πιο συγκεκριμένα, διαπιστώθηκε ότι όσο μεγαλύτερη είναι η χρήση των παραπάνω στοιχείων, τόσο ψηλότερο είναι το γλωσσικό επίπεδο αλλά και ο βαθμός δυσκολίας του κειμένου. Η διερεύνηση και ανακάλυψη αυτών των νέων παραγόντων θα συνδράμουν στην δημιουργία δοκιμασιών παραγωγής γραπτού λόγου με πιο αξιόπιστο και ακριβοδίκαιο τρόπο προς αλλοδαπούς υποψήφιους της ιταλικής Γλώσσας στην παραγωγή του γραπτού λόγου.

description: The present research aims at highlighting criteria, based on which the language level B and the degree of difficulty (readability) of a produced text can be measured and determined. For this purpose, 316 texts in Italian of the KPG exams for the periods of May 2015 and November 2016 of levels B1 and B2, produced by Greek users, were digitized in Word format. The READ-IT tool was used for data analysis and the SPSS.24 software for factor analysis. The results showed that the distinction between the two levels of language learning is based on grammar and syntax elements (spelling, use of subordinate clauses, polysyllabic words, etc.), but also on other important factors such as word and sentence coherence, lexical density, exam evaluation, READ-IT Global index etc. More specifically, it was found that the greater the use of the above elements, the higher the language level and the degree of difficulty of the text. Exploring and discovering these new factors will help create tests of written language production in a more reliable and equitable way for foreign candidates of the Italian Language in written production. On the other hand, future researchers are expected to use the present conclusions to discover new factors for levels A and C as well as for other languages.

description: The synthesis and characterization of PVA (Poly Vinyl Acetate) doped bulk MgB2 superconductor is reported here. PVA is used as a Carbon source. PVA doping effects made two distinguishable contributions: first enhancement of Jc field performance and second an increase in Hc2 value, both because of carbon incorporation into MgB2 crystal lattice. The susceptibility measurement reveals that Tc decreased from 37 to 36 K. Lattice parameter a decreased from 3.085 A to 3.081 A due to the partial substitution of Carbon at Boron site. PVA doped sample exhibited the Jc values greater than 10^5 A/cm2 at 5 & 10 K at low fields; which is almost 3 times higher than the pure one, while at high fields the Jc is increased by an order of magnitude in comparison to pure MgB2. From R(T)H measurements we found higher Tc values under magnetic field for doped sample; indicating an increase in Hc2. Also the magnetization measurements exhibited a significant enhancement in Hirr value. The improved performance of PVA doped MgB2 can be attributed to the substitution of carbon at boron site in parent MgB2 and the resulting impact on the carrier density and impurity scattering. The improved flux pinning behavior could easily be seen from reduced flux pinning force plots.

description: The irradiation behavior of graphite is essential for its applications in nuclear industry. However, the differences between graphite's behaviors are not well understood because of the very limited knowledge of microstructural differences between graphites. One typical structure, quinoline insoluble (QI) particle, was investigated using IG-110 and NBG-18 graphite. After irradiation, the QI particles on the polished surface were proved to become hillocks and can be easily identified by using a scanning electron microscope (SEM). Thus a method combining ion irradiation and SEM characterization was proposed to study the distribution and concentration of QI particles in graphite. During irradiation, the QI particles were found to evolve into densified spheres which have weak bonding with the surrounding graphite structures, indicating that the densification of QI particles does not contribute obviously to graphite dimensional shrinkage. A much higher concentration of QI particles in NBG-18 than IG-110 was characterized and is suggested to be responsible for the smaller maximum dimensional shrinkage of NBG-18 than IG-110 during irradiation.

description: Modified Newtonian dynamics (MOND) is a possible way to explain the flat galaxy rotation curves without invoking the existence of dark matter. It is however quite difficult to predict such a phenomenology in a consistent field theory, free of instabilities and admitting a well-posed Cauchy problem. We examine critically various proposals of the literature, and underline their successes and failures both from the experimental and the field-theoretical viewpoints. We exhibit new difficulties in both cases, and point out the hidden fine tuning of some models. On the other hand, we show that several published no-go theorems are based on hypotheses which may be unnecessary, so that the space of possible models is a priori larger. We examine a new route to reproduce the MOND physics, in which the field equations are particularly simple outside matter. However, the analysis of the field equations within matter (a crucial point which is often forgotten in the literature) exhibits a deadly problem, namely that they do not remain always hyperbolic. Incidentally, we prove that the same theoretical framework provides a stable and well-posed model able to reproduce the Pioneer anomaly without spoiling any of the precision tests of general relativity. Our conclusion is that all MOND-like models proposed in the literature, including the new ones examined in this paper, present serious difficulties: Not only they are unnaturally fine tuned, but they also fail to reproduce some experimental facts or are unstable or inconsistent as field theories. However, some frameworks, notably the tensor-vector-scalar (TeVeS) one of Bekenstein and Sanders, seem more promising than others, and our discussion underlines in which directions one should try to improve them.

description: No abstracts are to be cited without prior reference to the author.Although much effort has beenmade to evaluate criteria for marine egg and larval quality, the significance of poor egg quality for the results in the final juvenile production has not been clarified. It has often been claimed that surviving larvae from socalled poor egg quality groups would have the same viability as larvae from better performing egg groups. The aim of our experiments with turbot (Scophthalmus maximus) was to study whether the initial egg quality affected larval viability and growth up to the juvenile stage. Eggs from six individual females were quality evaluated according to fertilization rates, and the ratio of normal cell cleavages {blastomere morphology) at the 8-32 cell stage. Viability of yolk-sac larvae was tested by an acute high salinity stress test. The egg groups were incubated and the larvae were fed according to our standard feeding regime with microalgae, and enriched rotifers and Artemia nauplii. The results showed a significant positive correlation between,egg quality characteristics, hatching rates, larval tolerance to acute stress, survival and development until after metamorphosis. Larvae hatching from poor quality egg groups thus had a lower viability and were less able to develop normally to the juvenile stage than larvae from good quality egg groups. Our conclusion is that egg quality observed as fertilization rate and rates of normal blasto.meres at early egg stages is a good tool for evaluation of the potential juvenile production in turbot.

title: Theory and practice reflected in interaction in the Scottish Modern Languages classroom: four early career Modern Languages teachers' ideal-selves stories

description: In Second Language Acquisition (SLA) theory, Modern Language (ML) classroom research is characterised by interaction analysis and anthropological observation, with the aim to interpret the complexity of learning processes ‘inside the black box’. Yet, most of the recent interaction analysis which underpins SLA theory takes place in laboratory studies - outside the black box intending to replicate the conditions for learning inside the black box. The first aim of this thesis was to see whether SLA interaction theory was consonant with the observed ML secondary Scottish schools classrooms. I observed four early career ML teachers in four comprehensive secondary schools over a year. Linked to the first aim, as a teacher educator I was also interested in their Pedagogical Content Knowledge (PCK) development in terms of interaction in the target language. Semi-structured formal and informal interviews sought to elicit the four teachers’ perceptions of their PCK development in Communicative Teaching. Dörnyei’s Principled Communicative Approach (2009a) and Gass and Mackey’s Interaction Approach (2006) provided frameworks to explore the ways in which SLA theory was consonant with these four teachers’ practices. For the second research aim, I created an Early Career ML Teacher Development Framework to look into the four teachers’ pedagogical development. The study showed that SLA interaction theory was consonant with the studied classrooms, but with some caveats: I coined the term ‘ping-pong’ to capture the interaction observed, as an alternative to the IRF/IRE frameworks. In the field of SLA theory in the post-method era, the findings provide an important contribution to the understanding of the impact the alignment of Curriculum, Assessment and Pedagogy has in ML learning; the significance of the flow of language skills for classroom interaction and the role of target language use within Assessment is for Learning pedagogy. In the field of ML early career PCK development in interaction, this study is of great importance as it has provided a deep and detailed investigation of teachers’ interaction over one year, and it explored their development of understanding of the concepts underpinning their practices. The findings highlight the importance of agency and professional space as these aspects were crucial for the emergence of ML PCK in the field of interaction.

description: We consider entangled state production utilizing a full optomechanical arrangement, based on which we create entanglement between two far three-level V-type atoms using a quantum repeater protocol. At first, we consider eight identical atoms (1; 2;...; 8), while adjacent pairs (i; i + 1) with i = 1; 3; 5; 7 have been prepared in entangled states and the atoms 1, 8 are the two target atoms. The three-level atoms (1,2,3,4) and (5,6,7,8) distinctly become entangled with the system including optical and mechanical modes by performing the interaction in optomechanical cavities between atoms (2,3) and (6,7), respectively. Then, by operating appropriate measurements, instead of Bell state measurement which is a hard task in practical works, the entangled states of atoms (1,4) and (5,8) are achieved. Next, via interacting atoms (4,5) of the pairs (1,4) and (5,8) and operating proper measurement, the entangled state of target atoms (1,8) is obtained. In the continuation, entropy and success probability of the produced entangled state are then evaluated. It is observed that the time period of entropy is increased by increasing the mechanical frequency and by decreasing optomechanical coupling strength to the field modes. Also, in most cases, the maximum of success probability is increased by decreasing G and via decreasing.
Pion induced pion production on Oxygen at 280 MeV

description: A first coincident measurement of the pion induced pion production reaction cross-section on a complex nucleus (A > 2) has been successfully performed. In particular, the reaction ¹⁶O(π⁺,π⁺,π⁻) was measured at 280 MeV incident pion energy. The only previous published measures of this reaction on nuclei consisted of a dated measurement done on emulsion nuclei [BBD*69] and did not provide very stringent limits to the nuclear cross section. Single arm experiments have previously been done elsewhere on the proton [BJK*80] and the deuteron [PGM*84]. The reaction was measured at TRIUMF using the QQD magnetic spectrometer in coincidence with the CARUZ [RGR88], a total absorption scintillator range telescope. The measured four-fold differential cross sections were extrapolated to the unmeasured portions of the phase-space to extract the total reaction cross-section at 280 MeV, which was found to be σtot = 2.250 ± .350m6. The (π,2π) cross-section is thus observed to provide approximately 40% of the inclusive double charge exchange cross section [Woo84] at this energy. The model of [OV86] is found to explain many of the features of the data, including σtot. The present data do not preclude effects due to pion condensate precursor phenomena as proposed by [CE83] but they do not support the existence of a strong effect. The data are also compared to kinematical Monte Carlo simulations of some possible reaction mechanisms and it is found that the presence of an intermediate ∆ can aid the explanation of the low energy features of the π⁺ energy spectrum.
Complementary Pair Density Wave and d-wave Checkerboard Order in High Temperature Superconductors

description: The competing orders in the particle-particle (P-P) channel and the particle-hole (P-H) channel have been proposed separately to explain the pseudogap physics in cuprates. By solving the Bogoliubov-deGennes equation self-consistently, we show that there is a general complementary connection between the d-wave checkerboard order (DWCB) in the particle-hole (P-H) channel and the pair density wave order (PDW) in the particle-particle (P-P) channel. A small pair density localization generates DWCB and PDW orders simultaneously. The result suggests that suppressing superconductivity locally or globally through phase fluctuation should induce both orders in underdoped cuprates. The presence of both DWCB and PDW orders with $4a \times 4a$ periodicity can explain the checkerboard modulation observed in FT-STS from STM and the puzzling dichotomy between the nodal and antinodal regions as well as the characteristic features such as non-dispersive Fermi arc in the pseudogap state.

description: We study the critical behavior of magnetic thin films as a function of the film thickness. We use the ferromagnetic Ising model with the high-resolution multiple histogram Monte Carlo (MC) simulation. We show that though the 2D behavior remains dominant at small thicknesses, there is a systematic continuous deviation of the critical exponents from their 2D values. We observe that in the same range of varying thickness the deviation of the exponent $ν$ is very small from its 2D value, while exponent $β$ suffers a larger deviation. Moreover, as long as the film thickness is fixed, i. e. no finite size scaling is done in the $z$ direction perpendicular to the film, the 3D values of the critical exponents cannot be attained even with very large (but fixed) thickness. The crossover to 3D universality class cannot therefore take place without finite size scaling applied in the $z$ direction, in the limit of numerically accessible thicknesses. From values of exponent $α$ obtained by MC, we estimate the effective dimension of the system. We conclude that with regard to the critical behavior, thin films behave as systems with effective dimension between 2 and 3.

Superconductivity in zigzag CuO chains

description: Superconductivity has recently been discovered in Pr$_{2}$Ba$_{4}$Cu$_{7}$O$_{15-δ}$ with a maximum $T_c$ of about 15K. Since the CuO planes in this material are believed to be insulating, it has been proposed that the superconductivity occurs in the double (or zigzag) CuO chain layer. On phenomenological grounds, we propose a theoretical interpretation of the experimental results in terms of a new phase for the zigzag chain, labelled by C$_1$S$_{3/2}$. This phase has a gap for some of the relative spin and charge modes but no total spin gap, and can have a divergent superconducting susceptibility for repulsive interactions. A microscopic model for the zigzag CuO chain is proposed, and on the basis of density matrix renormalization group (DMRG) and bosonization studies of this model, we adduce evidence that supports our proposal.

description: We evaluate the pion-nucleon and the pion-Delta sigma terms by employing the method of quantum chromodynamics (QCD) sum rules. The obtained value of the pion-nucleon sigma term is compatible with the larger values already anticipated by the recent calculations. It is also found that the pion-Delta sigma term is as large as the pion-nucleon sigma term.

Do single photons tunnel faster than light?

description: Experiments done in the early 1990's produced a surprising result: that single photons pass through a photonic tunnel barrier with a group velocity faster than the vacuum speed of light. Subsequent experiments with classical pulses have also revealed apparent superluminal group velocities as well as tunneling times that saturate with barrier length, a phenomenon known as the Hartman effect. In this paper we show that the measured delays are in fact cavity lifetimes as opposed to transit times. This interpretation resolves the Hartman paradox and shows that tunneling is not superluminal as widely believed.

title: The Role Of Young Cephalopods In Food Webs And Their Environment: A Major Gap In Our Knowledge

description: No abstracts are to be cited without prior reference to the author.I review the lack of information on the role of early life history stages of cephalopods in ecosystems. The egg stages of pelagic spawning species are almost unknown, although spawning aggregations have been documented. Egg masses of some benthic spawners can be very abundant, covering the bottom in fairly large local areas, but few records indicate anything eating them. Paralarvae must be abundant to account for the numbers of adults caught by fishing and .by other predators (with some left over to reproduce). However, numbers of paralarvae sampled by plankton nets are, with very few exceptions, very low. In spite of much speculation, we don't actually know what the paralarvae eat, much less their feeding rates. Thus, even if we knew their abundance, we couldn't calculate their impact as micropredators. We know even less about what is eating young cephalopods; few publications contribute any infonnation about predation on paralarvae. Although most cephalopod mortality probably occurs during. early stages, we can't confidently infer much about the major likely sources of mortality: starvation and predation.

Rapid planetesimal formation in turbulent circumstellar discs

description: The initial stages of planet formation in circumstellar gas discs proceed via dust grains that collide and build up larger and larger bodies (Safronov 1969). How this process continues from metre-sized boulders to kilometre-scale planetesimals is a major unsolved problem (Dominik et al. 2007): boulders stick together poorly (Benz 2000), and spiral into the protostar in a few hundred orbits due to a head wind from the slower rotating gas (Weidenschilling 1977). Gravitational collapse of the solid component has been suggested to overcome this barrier (Safronov 1969, Goldreich & Ward 1973, Youdin & Shu 2002). Even low levels of turbulence, however, inhibit sedimentation of solids to a sufficiently dense midplane layer (Weidenschilling & Cuzzi 1993, Dominik et al. 2007), but turbulence must be present to explain observed gas accretion in protostellar discs (Hartmann 1998). Here we report the discovery of efficient gravitational collapse of boulders in locally overdense regions in the midplane. The boulders concentrate initially in transient high pressures in the turbulent gas (Johansen, Klahr, & Henning 2006), and these concentrations are augmented a further order of magnitude by a streaming instability (Youdin & Goodman 2005, Johansen, Henning, & Klahr 2006, Johansen & Youdin 2007) driven by the relative flow of gas and solids. We find that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes. Gravitational collapse happens much faster than radial drift, offering a possible path to planetesimal formation in accreting circumstellar discs.
