description: Background: Heavy-ion induced two-nucleon transfer reactions are powerful tools to reveal peculiar aspects of the atomic nucleus, such as pairing correlations, single-particle and collective degrees of freedom, and more. Also, these processes are in competition with the direct meson exchange in the double charge exchange reactions, which have recently attracted great interest due to their possible connection to neutrinoless double-beta decay. In this framework, the exploration of two-nucleon transfer reactions in the 20Ne+116Cd collision at energies above the Coulomb barrier is particularly relevant since the 116Cd nucleus is a candidate for the double-beta decay. Methods: We measured the excitation energy spectra and absolute cross sections for the two reactions using the MAGNEX large acceptance magnetic spectrometer to detect the ejectiles. We performed direct coupled reaction channels and sequential distorted wave Born approximation calculations using the double folding São Paulo potential to model the initial and final state interactions. The spectroscopic amplitudes for two- and singleparticle transitions were derived by different nuclear structure approaches: microscopic large-scale shell model, interacting boson model-2 and quasiparticle random phase approximation. Results: The calculations are able to reproduce the experimental cross sections for both two-neutron and twoproton transfer reactions. The role of couplings with the inelastic channels are found to be important in the two-proton transfer case. A competition between the direct and the sequential process is found in the reaction mechanism. For the two-proton transfer case, the inclusion of the 1g7/2 and 2d5/2 orbitals in the model space is crucial.

description: We evaluate background rejection capabilities and physics performance of a detector composed of two diverse elements: a sensitive target (filled with one or two species of liquefied noble gasses) and an active veto (made of Gd-doped ultra-pure water). A GEANT4 simulation shows that for a direct WIMP search, this device can reduce the neutron background to O(1) event per year per tonne of material. Our calculation shows that an exposure of one tonne $\times$ year will suffice to exclude spin-independent WIMP-nucleon cross sections ranging from $10^{-9}$ pb to $10^{-10}$ pb.

description: We have carried out a systematic study of the PbO-type compound FeSe_{1-x}Te_x (x = 0~1), where Te substitution effect on superconductivity is investigated. It is found that superconducting transition temperature reaches a maximum of Tc=15.2K at about 50% Te substitution. The pressure-enhanced Tc of FeSe0.5Te0.5 is more than 10 times larger than that of FeSe. Interestingly, FeTe is no longer superconducting. A low temperature structural distortion changes FeTe from triclinic symmetry to orthorhombic symmetry. We believe that this structural change breaks the magnetic symmetry and suppresses superconductivity in FeTe.

The recently developed "S" and "G" versions of our codes, that consider multifragmentation of nuclei formed after the preequilibrium stage of reactions when their excitation energy is above 2A MeV using the Statistical Multifragmentation Model (SMM) code by Botvina et al. ("S" stands for SMM) and the fission-like binary-decay model GEMINI by Charity ("G" stands for GEMINI), respectively, are briefly described as well. Examples of benchmarking our models against a large variety of experimental data on particle-particle, particle-nucleus, and nucleus-nucleus reactions are presented. Open questions on reaction mechanisms and future necessary work are outlined.

description: Samples of Nd(2-x)Ce(x)CuO(4), an electron-doped high temperature superconducting cuprate (HTSC), near optimal doping at x = 0.155 were measured via angle resolved photoemission (ARPES). We report a renormalization feature in the self energy ("kink") in the band dispersion at 50 - 60 meV present in nodal and antinodal cuts across the Fermi surface. Specifically, while the kink had previously only been seen in the antinodal region, it is now observed also in the nodal region, reminiscent of what has been observed in hole-doped cuprates.

description: Using a linear combination of atomic orbitals approach, we report a systematic comparison of various Density Functional Theory (DFT) and hybrid exchange-correlation functionals for the prediction of the electronic and structural properties of prototypical ferroelectric oxides. It is found that none of the available functionals is able to provide, at the same time, accurate electronic and structural properties of the cubic and tetragonal phases of BaTiO$_3$ and PbTiO$_3$. Some, although not all, usual DFT functionals predict the structure with acceptable accuracy, but always underestimate the electronic band gaps. Conversely, common hybrid functionals yield an improved description of the band gaps, but overestimate the volume and atomic distortions associated to ferroelectricity, giving rise to an unacceptably large $c/a$ ratio for the tetragonal phases of both compounds. This super-tetragonality is found to be induced mainly by the exchange energy corresponding to the Generalized Gradient Approximation (GGA) and, to a lesser extent, by the exact exchange term of the hybrid functional. We thus propose an alternative functional that mixes exact exchange with the recently proposed GGA of Wu and Cohen [Phys. Rev. B 73, 235116 (2006)] which, for solids, improves over the treatment of exchange of the most usual GGA's. The new functional renders an accurate description of both the structural and electronic properties of typical ferroelectric oxides.

An evaluation of the role, theory, and practice of the occupation of homemaker
Creators: name: Auman, Jane Tate
Publisher: name: University of British Columbia
Year: 2010

description: A homemaker is an individual who is employed by a homemaking agency for the purpose of providing in-home service to specific clients. These client services involve housekeeping and/or personal care assistance. Until now little research has been done in the area of homemaking as an occupation. Therefore, this study is intended to provide research background for present and future work concerning the homemakers in the areas of their role change, theory, and practice. Using the data base obtained from supervisor case notes of homemaker clients in the years 1976 and 1980, this study attempted to look at the role changes that occurred and the discrepancy that existed between the practice of homemakers in an agency and the practice its homemakers were taught within the classroom. The sample data was derived from one hundred client files each from 1976 and from 1980. The individual files were randomly selected from the files of a large metropolitan homemaker agency within the province of British Columbia. The corresponding curriculum that was used in this study is the Homemaker Program of the Vancouver Community College, Vancouver, B.C., as taught in 1980. Methodology for this research included statistical analyses of the client file data and use of the Provus Discrepancy Evaluation Model, in which the actual practice of the homemaker and the formal curriculum of homemaker training were compared. Findings of the research are that the client of 1980 appeared to be older, was representative of a numerically smaller household, and depended on others for referral to the homemaker agency. Cross-tabulations of the years (1976 and 1980) with a variety of health and demographic indicators display statistically significant increase in 1980 of clients who had psychological and medical-surgical problems. However, child-care related problems for these clients decreased significantly in 1980. The category of homemaker practice, meaning the duties that the homemaker was indicated as having been required to perform in the client's home, also showed areas of significant statistical change. Cross-tabulations of these years indicate that personal care and housekeeping practice had increased significantly by 1980. Homemaker practice related to assistance with child care in the home decreased in 1980. A discrepancy analysis between the practice of the homemaker in the client's home and their corresponding curriculum of the homemaker training program indicated congruency for eight of the eleven practice categories. The areas of discrepancy were: 1) replace Home Care nurse (temporarily); 2) assist with the administration of medications; and 3) monitor state of health. The homemaker organization is a service oriented group in which rapid role changes are occurring, accompanied by the evidence of some apparent discrepancies between curricular theory and. actual practice.
The use of videotapes in early childhood education
Creators: name: Weisz, Iolanda
Publisher: name: University of British Columbia
Year: 2010

description: In the realm of modern educational media, verbal and scientific support has been given to the potential of videotape for teaching and learning specific skills. Little evidence, however, can be found to substantiate, the support in early childhood teacher training. This lack of sufficient evidence pertaining to the effectiveness and possibilities for use of videotapes as a teaching aid in early childhood teacher training, served as the motivating force for the present study. The first purpose of this study was to accumulate videotaped data about four target children who displayed different natural behaviours during chosen free play activities,and to develop a systematic observational plan for analysis of videotaped information. The second purpose of this study was to test the effectiveness of videotaped records displaying children's behaviour used with structured observational guidelines to help pre-service and in-service teachers become more accurate observers of young children's natural behaviour. Two basic procedures were used in this study. (1) To accumulate videotaped data about young children's behaviour, four target children were selected and videotaped. A 20 minute continuous free play activity was retained as a "record tape" for each target child. For analysis of obtained videotaped records, a systematic observational plan was developed. (2) To test the effectiveness of videotapes used in connection with structured observational guidelines, the following procedures were used: Subjects of the study were 23 pre-service and inservice teachers enrolled in an Early Childhood curriculum and instruction class at the University of British Columbia. Pre-service and inservice teachers were asked to observe without interruption a 15 minute segment of videotape No. 1 entitled "Kevin and Aaron". When the videotape showing ended, all the subjects were asked to write a description of what they saw using the guide sheets. Three types of guide sheets were administered to the same group at one week time intervals between each test. After completion of the observation guide sheets, all subjects were asked to evaluate the videotaped observations and guide sheets used. From analysis of videotaped records, it was concluded that the kindergarten classroom is a remarkably busy place and each child has unique and special qualities. All the children do not think identically, are not equally skilled nor are they interested in or concerned by identical problems. Results of analysis carried out in the pilot study suggest a significant difference between test scores obtained on observation Type 1 and Type 3, indicating a preference for the most structured guide sheet.
Measuring the Higgs-Vector boson Couplings at Linear $e^{+} e^{-}$ Collider

description: We estimate the accuracy with which the coefficient of the CP even dimension six operators involving Higgs and two vector bosons (HVV) can be measured at linear $e^+ e^-$ colliders. Using the optimal observables method for the kinematic distributions, our analysis is based on the five different processes. First is the WW fusion process in the t-channel ($e^+e^- \to \barν_e ν_e H$), where we use the rapidity y and the transverse momentum $\pT$ of the Higgs boson as observables. Second is the ZH pair production process in the s-channel, where we use the scattering angle of the Z and the Z decay angular distributions, reproducing the results of the previous studies. Third is the t-channel ZZ, fusion processes ($e^+e^- \to e^+e^ -H$), where we use the energy and angular distributions of the tagged $e^+$ and $e^-$. In the fourth, we consider the rapidity distribution of the untagged $e^+e^-H$ events, which can be approximated well as the $γγ$ fusion of the bremsstrahlung photons from $e^+$ and $e^-$ beams. As the last process,we consider the single tagged $e^+e^- H$ events, which probe the $γe^{\pm} \to H e^{\pm}$ process. All the results are presented in such a way that statistical errors of the constraints on the effective couplings and their correlations are read off when all of them are allowed to vary simultaneously, for each of the above processes, for $m_H=120 $ GeV, at $\sqrt{s}=250\GEV$, $350\GEV$ $500\GEV$ and $1\TEV$, with and without $e^-$ beam polarization of 80%.

description: We have calculated the strength distributions of the giant monopole resonance in the even-A tin isotopes (A = 112-124) which were recently measured in inelastic $α$-scattering. The calculations were performed within two microscopic models: the quasiparticle random phase approximation (QRPA) and the quasiparticle time blocking approximation which is an extension of the QRPA including quasiparticle-phonon coupling. We used a self-consistent calculational scheme based on the HF+BCS approximation. The single-particle continuum was exactly included on the RPA level. The self-consistent mean field and the effective interaction were derived from the Skyrme energy functional. In the calculations, two Skyrme force parametrizations were used. The T5 parametrization with comparatively low value of the incompressibility of infinite nuclear matter ($K_{\infty}$ = 202 MeV) gives theoretical results in good agreement with the experimental data including the resonance widths.

description: Four new resin glycosides with macrolactone structures (jalapins), namely, calyhedins VII (1)–X (4), were isolated from the rhizomes of Calystegia hederacea Wall. (Convolvulaceae). The structures of 1–4 were determined based on spectroscopic data. They were classified into three ring types: a 27-membered ring (1), a 22-membered ring (2, 3), and a 23-membered ring (4). Their sugar moieties were partially acylated using five organic acids, including (E)-2-methylbut-2-enoic acid, 2S-methylbutyric acid, and 2 R-methyl-3R-hydroxybutyric acid. Compound 4 was the first genuine resin glycoside with calyhedic acid F as the glycosidic acid component. Additionally, the cytotoxic activities of 1, 2, and 4 towards HL-60 human promyelocytic leukaemia cells were evaluated. All compounds demonstrated almost the same activity as the positive control, cisplatin.

description: The ground state of a spinor Bose liquid is ferromagnetic, while the softest excitation above the ground state is the magnon mode. The dispersion relation of the magnon in a one-dimensional liquid is periodic in the wavenumber q with the period 2πn, determined by the density n of the liquid. Dynamic correlation functions, such as e.g. spin-spin correlation function, exhibit power-law singularities at the magnon spectrum, $ω\toω_m(q,n)$. Without using any specific model of the inter-particle interactions, we relate the corresponding exponents to independently measurable quantities $\partialω_m/\partial q$ and $\partialω_m/\partial n$.

description: The sequence-dependent folding landscapes of nucleic acid hairpins reflect much of the complexity of biomolecular folding. Folding trajectories, generated using single molecule force clamp experiments by attaching semiflexible polymers to the ends of hairpins have been used to infer their folding landscapes. Using simulations and theory, we study the effect of the dynamics of the attached handles on the handle-free RNA free energy profile $F^o_{eq}(z_m)$, where $z_m$ is the molecular extension of the hairpin. Accurate measurements of $F^o_{eq}(z_m)$ requires stiff polymers with small $L/l_p$, where $L$ is the contour length of the handle, and $l_p$ is the persistence length. Paradoxically, reliable estimates of the hopping rates can only be made using flexible handles. Nevertheless, we show that the equilibrium free energy profile $F^o_{eq}(z_m)$ at an external tension $f_m$, the force ($f$) at which the folded and unfolded states are equally populated, in conjunction with Kramers' theory, can provide accurate estimates of the force-dependent hopping rates in the absence of handles at arbitrary values of $f$. Our theoretical framework shows that $z_m$ is a good reaction coordinate for nucleic acid hairpins under tension.

description: We study n-point tree amplitudes of N=4 super Yang-Mills theory and N=8 supergravity for general configurations of external particles of the two theories. We construct generating functions for n-point MHV and NMHV amplitudes with general external states. Amplitudes derived from them obey SUSY Ward identities, and the generating functions characterize and count amplitudes in the MHV and NMHV sectors. The MHV generating function provides an efficient way to perform the intermediate state helicity sums required to obtain loop amplitudes from trees. The NMHV generating functions rely on the MHV-vertex expansion obtained from recursion relations associated with a 3-line shift of external momenta involving a reference spinor |X]. The recursion relations remain valid for a subset of N=8 supergravity amplitudes which do not vanish asymptotically for all |X]. The MHV-vertex expansion of the n-graviton NMHV amplitude for n=5,6,...,11 is independent of |X] and exhibits the asymptotic behavior z^{n-12}. This presages difficulties for n > 12. Generating functions show how the symmetries of supergravity can be implemented in the quadratic map between supergravity and gauge theory embodied in the KLT and other similar relations between amplitudes in the two theories.

description: We use two-flavor chiral perturbation theory to describe hyperons. We focus on the strangeness conserving sector, and, as an example, calculate hyperon masses. Convergence of this two-flavor chiral expansion for observables is improved over the three-flavor theory. The cost, however, is a larger number of low-energy constants that must be ultimately determined from lattice QCD data. A formula for the mass of the omega baryon is derived to sixth order in this expansion, and will aid lattice practitioners in scale setting or tuning the strange quark mass.

description: Single-nucleon transfer reactions are processes that selectively probe single-particle components of the populated many-body nuclear states. In this context, recent efforts have been made to build a unified description of the rich nuclear spectroscopy accessible in heavy-ion collisions. An example of this multichannel approach is the study of the competition between successive nucleon transfer and charge exchange reactions, the latter being of particular interest in the context of single and double beta decay studies. To this extent, the one-proton pickup reaction $^{48}$Ti($^{18}$O,$^{19}$F)$^{47}$Sc at 275 MeV was measured for the first time, under the NUMEN experimental campaign. Differential cross-section angular distribution measurements for the $^{19}$F ejectiles were performed at INFN-LNS in Catania by using the MAGNEX large acceptance magnetic spectrometer. The data were analyzed within the distorted-wave and coupled-channels Born approximation frameworks. The initial and final-state interactions were described adopting the São Paulo potential, whereas the spectroscopic amplitudes for the projectile and target overlaps were derived from shell-model calculations. The theoretical cross sections are found to be in very good agreement with the experimental data, suggesting the validity of the optical potentials and the shell-model description of the involved nuclear states within the adopted model space.

description: We demonstrate experimentally that a single Rb atom excited to the $79d_{5/2}$ level blocks the subsequent excitation of a second atom located more than $10 μ\rm m$ away. The observed probability of double excitation of $\sim 30%$ is consistent with a theoretical model based on calculations of the long range dipole-dipole interaction between atoms.

Blind Date: Using proper motions to determine the ages of historical images

description: Astrometric calibration is based on patterns of cataloged stars and therefore effectively assumes a particular epoch, which can be substantially incorrect for historical images. With the known proper motions of stars we can "run back the clock" to an approximation of the night sky in any given year, and in principle the year that best fits stellar patterns in any given image is an estimate of the year in which that image was taken. In this paper we use 47 scanned photographic images of M44 spanning years 1910-1975 to demonstrate this technique. We use only the pixel information in the images; we use no prior information or meta-data about image pointing, scale, orientation, or date. Blind Date returns date meta-data for the input images. It also improves the astrometric calibration of the image because the final astrometric calibration is performed at the appropriate epoch. The accuracy and reliability of Blind Date are functions of image size, pointing, angular resolution, and depth; performance is related to the sum of proper-motion signal-to-noise ratios for catalog stars measured in the input image. All of the science-quality images and 85 percent of the low-quality images in our sample of photographic plate images of M44 have their dates reliably determined to within a decade, many to within months.

description: The PUNCH4NFDI consortium bundles numerous efforts in data management of the communities of particle physics, astroparticle physics, hadron & nuclear physics, and astronomy. These communities have decade-long leadership experience in topics as diverse as "big data", "open data", distributed computing, use of heterogeneous resources, serving user groups of literally thousands of scientists with data scratching the Exabyte regime. Organised in 7 task areas, the consortium ultimately aims at establishing FAIR digital research products for its communities and beyond, spending their entire lifecycle inside a "science data platform" that offers all storage and compute opportunities and all data transformation possibilities required for making the data fully productive in a sustainable way. In its efforts, the consortium reaches out to the entire NFDI and beyond and is fully integrated into European and international endeavours, always looking for synergies with other initiatives and other fields of science. Training and education plans round off the consortium's ambitious programme.

description: 56. Lasiocampidae – tent caterpillars and lappet moths Robust, medium-sized to very large (25–120 mm wingspan) moths, often drably colored and with reduced or simplified wing patterns. Males generally have conspicuously plumose antennae. Larval hosts are primarily trees and shrubs. Th e most familiar and biologically best-known North American lasiocampids are undoubtedly the tent caterpillars (Malacosoma spp.), as a result of the huge numbers of caterpillars present during periodic outbreaks. Th e vast body of literature on Malacosoma ecology and biology is testament to this; for an excellent introduction to tent caterpillar ecology see Fitzgerald (1995). The family Lasiocampidae includes about 1500 species distributed worldwide (Lemaire and Minet 1999), with about 30 species in North America and five reported from AB. Th ey are most diverse in the tropics. Franclemont (1973) provided a diagnosis of the North American species. Th e taxonomy of the New World Malacosoma was revised by Stehr and Cook (1968). Despite their notoriety, a number of significant taxonomic uncertainties remain among the western taxa, and there is perhaps no better place than AB to investigate this; for example, see the notes on Malacosoma californica.

Pion pole light-by-light contribution to g-2 of the muon in a nonlocal chiral quark model

description: We calculate the pion pole term of the light-by-light contribution to the $g-2$ of the muon in the framework of an effective chiral quark model with instanton-like nonlocal quark--quark interaction. The full kinematic dependence of the pion-photon transition form factors is taken into account. The dependence of form factors on the pion virtuality decreases the result by about 15% in comparison to the calculation where this dependence is neglected. Further, it is demonstrated that the QCD constraints suggested by Melnikov and Vainshtein are satisfied within the model. The corresponding contributions originate from the box diagram as well from the pion-pole term. Our chiral nonlocal model result for the pion-pole light-by-light contribution to $(g-2)/2$ of the muon is $(6.3-6.7) \cdot10^{-10}$, which is in the ball park of other effective-model calculations.

description: The aim of the present review is to introduce the reader to some of the physical notions and of the mathematical methods that are relevant to the study of nonlinear waves in Bose-Einstein Condensates (BECs). Upon introducing the general framework, we discuss the prototypical models that are relevant to this setting for different dimensions and different potentials confining the atoms. We analyze some of the model properties and explore their typical wave solutions (plane wave solutions, bright, dark, gap solitons, as well as vortices). We then offer a collection of mathematical methods that can be used to understand the existence, stability and dynamics of nonlinear waves in such BECs, either directly or starting from different types of limits (e.g., the linear or the nonlinear limit, or the discrete limit of the corresponding equation). Finally, we consider some special topics involving more recent developments, and experimental setups in which there is still considerable need for developing mathematical as well as computational tools.

description: If a central vector potential V(r,a) in the Dirac equation is monotone in a parameter 'a', then a discrete eigenvalue E(a) is monotone in 'a'. For such a special class of comparisons, this generalizes an earlier comparison theorem that was restricted to node free states. Moreover, the present theorem applies to every discrete eigenvalue.

A Multivariate Fast Discrete Walsh Transform with an Application to Function Interpolation

description: For high dimensional problems, such as approximation and integration, one cannot afford to sample on a grid because of the curse of dimensionality. An attractive alternative is to sample on a low discrepancy set, such as an integration lattice or a digital net. This article introduces a multivariate fast discrete Walsh transform for data sampled on a digital net that requires only $O(N \log N)$ operations, where $N$ is the number of data points. This algorithm and its inverse are digital analogs of multivariate fast Fourier transforms. This fast discrete Walsh transform and its inverse may be used to approximate the Walsh coefficients of a function and then construct a spline interpolant of the function. This interpolant may then be used to estimate the function's effective dimension, an important concept in the theory of numerical multivariate integration. Numerical results for various functions are presented.
Evolution of Oscillating Scalar Fields as Dark Energy

description: Oscillating scalar fields, with an oscillation frequency much greater than the expansion rate, have been proposed as models for dark energy. We examine these models, with particular emphasis on the evolution of the ratio of the oscillation frequency to the expansion rate. We show that this ratio always increases with time if the dark energy density declines less rapidly than the background energy density. This allows us to classify oscillating dark energy models in terms of the epoch at which the oscillation frequency exceeds the expansion rate, which is effectively the time at which rapid oscillations begin. There are three basic types of behavior: early oscillation models, in which oscillations begin during the matter-dominated era, late oscillation models, in which oscillations begin after scalar-field domination, and non-oscillating models. We examine a representative set of models (those with power-law potentials) and determine the parameter range giving acceptable agreement with the supernova observations. We show that a subset of all three classes of models can be consistent with the observational data.
