description: Most measurements of critical current densities in YBa$_2$Cu$_3$O$_{7-δ}$ thin films to date have been performed on films where the \textit{c}-axis is grown normal to the film surface. With such films, the analysis of the dependence of $j_c$ on the magnetic field angle is complex. The effects of extrinsic contributions to the angular field dependence of $j_c$, such as the measurement geometry and disposition of pinning centres, are convoluted with those intrinsically due to the anisotropy of the material. As a consequence of this, it is difficult to distinguish between proposed FLL structure models on the basis of angular critical current density measurements on \textit{c}-axis films. Films grown on mis-cut (vicinal) substrates have a reduced measurement symmetry and thus provide a greater insight into the critical current anisotropy. In this paper previous descriptions of the magnetic field angle dependence of $j_c$ in YBa$_2$Cu$_3$O$_{7-δ}$ are reviewed. Measurements on YBa$_2$Cu$_3$O$_{7-δ}$ thin films grown on a range of vicinal substrates are presented and the results interpreted in terms of the structure and dimensionality of the FLL in YBa$_2$Cu$_3$O$_{7-δ}$. There is strong evidence for a transition in the structure of the flux line lattice depending on magnetic field magnitude, orientation and temperature. As a consequence, a simple scaling law can not, by itself, describe the observed critical current anisotropy in YBa$_2$Cu$_3$O$_{7-δ}$. The experimentally obtained $j_c(θ)$ behaviour of YBCO is successfully described in terms of a kinked vortex structure for fields applied near parallel to the \textit{a-b} planes.

BBGKY Hierarchy Underlying Many Particle Quantum Mechanics

description: Recently, the one particle quantum mechanics has been obtained in the framework of an entirely classical subquantum kinetics. In the present paper we argue that, within the same scheme and without any additional assumption, it is possible to obtain also the $n$-particle non relativistic quantum mechanics. The main goal of the present effort is to show that the classical BBGKY hierarchical equation, for the $n$-particle reduced distribution function, is the ancestor of the $n$-particle Schrödinger equation. On the other hand we show that within the scenario of the subquantum structure of quantum particle, the Fisher information measure emerges naturally in quantum mechanics.

description: The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiodic systems, while MEs may exist for certain cases, the analytic results which allow for an exact understanding are rare. Here we uncover a class of exactly solvable 1D models with MEs in the spectra, where quasiperiodic on-site potentials are inlaid in the lattice with equally spaced sites. The analytical solutions provide the exact results not only for the MEs, but also for the localization and extended features of all states in the spectra, as derived through computing the Lyapunov exponents from Avila's global theory, and also numerically verified by calculating the fractal dimension. We further propose a novel scheme with experimental feasibility to realize our model based on an optical Raman lattice, which paves the way for experimental exploration of the predicted exact ME physics.

Subjects: Prime Numbers, Primal Invariance, Arithmetic Space-Time, Exact Prime Counting, Number Theory, Special Relativity, Cryptography

description:  

 

This work introduces the Primal Invariance Axiom, a new mathematical framework that treats prime numbers as invariant events in arithmetic space-time.

Inspired by the invariance of the speed of light in Special Relativity, the author proposes an exact counting function, πinv(x)\pi_{\text{inv}}(x), which aims to replace statistical approximations such as x/log⁡xx/\log x or Li(x)\mathrm{Li}(x). The study also includes a thought experiment analogous to relativistic observation, reinforcing the view of primes as fixed and measurable informational structures.

The material includes the main academic article, Python source code for computing and plotting the prime distribution, and a comparative graph of πinv(x)\pi_{\text{inv}}(x) and Gauss’s approximation.

Applications are suggested in number theory, theoretical physics, cryptography, and information systems.

description: We update a previously-proposed set of supersymmetric benchmark scenarios, taking into account the precise constraints on the cold dark matter density obtained by combining WMAP and other cosmological data, as well as the LEP and b -> s gamma constraints. We assume that R parity is conserved and work within the constrained MSSM (CMSSM) with universal soft supersymmetry-breaking scalar and gaugino masses m_0 and m_1/2. In most cases, the relic density calculated for the previous benchmarks may be brought within the WMAP range by reducing slightly m_0, but in two cases more substantial changes in m_0 and m_1/2 are made. Since the WMAP constraint reduces the effective dimensionality of the CMSSM parameter space, one may study phenomenology along `WMAP lines' in the (m_1/2, m_0) plane that have acceptable amounts of dark matter. We discuss the production, decays and detectability of sparticles along these lines, at the LHC and at linear e+ e- colliders in the sub- and multi-TeV ranges, stressing the complementarity of hadron and lepton colliders, and with particular emphasis on the neutralino sector. Finally, we preview the accuracy with which one might be able to predict the density of supersymmetric cold dark matter using collider measurements.

description: In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For $d=1$, the best fit result is $Ω^0_m = 0.25$, the equation of the state of the holographic dark energy $w^0_\d = -0.91$ and the transition between the decelerating expansion and the accelerating expansion happened when the cosmological red-shift was $z_T=0.72$. If we set $d$ as a free parameter, the best fit results are $d=0.21$, $Ω_m^0=0.46$, $w_\d^0=-2.67$, which sounds like a phantom today, and the transition redshift is $z_T=0.28$.

description: The paper presents a numerical implementation of the gravitational N-body problem with contact interactions between non-spherically shaped bodies. The work builds up on a previous implementation of the code and extends its capabilities. The number of bodies handled is significantly increased through the use of a CUDA/GPU-parallel octree structure. The implementation of the code is discussed and its performance are compared against direct N$^2$ integration. The code features both smooth (force-based) and non-smooth (impulse-based) methods, as well as a visco-elastic non-smooth method, to handle contact interaction between bodies. The numerical problem of simulating "rubble-pile" asteroid gravitational aggregation processes is addressed. We discuss the features of the problem and derive criteria to set up the numerical simulation from the dynamical constraints of the combined gravitational-collisional problem. Examples of asteroid aggregation scenarios that could benefit from such implementation are finally presented.

Year: 2011

description: The Census Dissemination Unit (CDU) at Mimas provides access to the Census aggregate datasets for the UK academic community and champions the needs of that community in discussions with the Office for National Statistics (ONS), the UK statistics authority. This paper will describe how the CDU engaged with the ONS to develop a new way that aggregate census statistics are stored, delivered and used, working in collaboration with them to revolutionise the data delivery mechanism for the 2011 Census. The ONS is now committed to using these ideas to create a 'data feed' approach to delivering the 2011 Census. What has developed is a synergistic relationship that allows the transfer of knowledge from the academic community and utilises the skills of both parties to develop ideas and products that will enhance the way that the 2011 Census is used not only by the academic community, but by business, government and third party census application developers. The ONS is currently co-funding a project at the CDU to create test datasets for use in developing an Application Programming Interface that the CDU and other developers can utilise to develop applications for delivering census data to their respective communities.

A 3S1 cusp is identified in the inverse process Lambda-bar Lambda to pbar-p at threshold using detailed balance. Partial wave amplitudes for pbar-p 3P0, 3F3, 3D3 and 3G3 exhibit a behaviour very similar to resonances observed in Crystal Barrel data. With this identification, the pbar-p to Lambda-bar Lambda data then provide evidence for a new I = 0, J^{PC} = 1^{--} resonance with mass M = 2290 +- 20 MeV, Gamma = 275 +- 35 MeV, coupling to both 3S1 and 3D1.

description: The magnitudes of gluon and four-quark condensates are found from the analysis of vector mesons consisting of light quarks (the families of $ρ$ and $ω$ mesons) in the 3 loops approximation. The QCD model with infinite number of vector mesons is used to describe the function $R(s)$. This model describes well the experimental function $R(s)$. Polarization operators calculated with this model coincide with the Wilson operator expansion at large $Q^2$. The improved perturbative theory, such that the polarization operators have correct analytical properties, is used. The result is $<0 | (α_s/π) G^2 | 0 > = 0.062 \pm 0.019 GeV^4$. The electronic widths of $ρ(1450)$ and $ω(1420)$ are calculated.

description: The current algebra for gauge theories like QCD at finite temperature and density is studied. We start considering, the massless Thirring model at finite temperature and density, finding an explicit expression for the current algebra. The central charge only depends on the coupling constant and there are not new effects due to temperature and density. From this calculation, we argue how to compute the central charge for $QCD_4$ and we argue why the central charge in four dimensions could be modified by finite temperature and density.

description: [Ca$_2$CoO$_3$]$_{0.62}$[CoO$_2$], a two dimensional misfit metallic compound, is famous for its rich phases accessed by temperature, $i.e.$ high temperature spin-state transition, metal-insulator transition (MIT) at intermediate temperature ($\sim$ 100 K) and low temperature spin density wave (SDW). It enters into SDW phase below T$_{MIT}$ which becomes long range at 27 K. Information on the independent role of misfit layers (rocksalt/Ca$_2$CoO$_3$ \& triangular/CoO$_2$) in these phases is scarce. By combining a set of complementary macroscopic (DC magnetization and resistivity) and microscopic (neutron diffraction and X-ray absorption fine structure spectroscopy) measurements on pure (CCO) and Tb substituted in the rocksalt layer of CCO (CCO1), magnetic correlations in both subsystems of this misfit compound are unraveled. CCO is found to exhibit glassiness, as well as exchange bias (EB) effects, while CCO1 does not exhibit glassiness, albeit it shows weaker EB effect. By combining local structure investigations from extended X-ray absorption fine structure (EXAFS) spectroscopy and neutron diffraction results on CCO, we confirm that the SDW arises in the CoO$_2$ layer. Our results show that the magnetocrystalline anisotropy associated with the rocksalt layer acts as a source of pinning, which is responsible for EB effect. Ferromagnetic clusters in the Ca$_2$CoO$_3$ affects SDW in CoO$_2$ and ultimately glassiness arises.

description: Transition metal complexes are ubiquitous in biology and chemical catalysis, yet they remain difficult to accurately describe with ab initio methods due to the presence of a large degree of dynamic electron correlation, and, in some cases, strong static correlation which results from a manifold of low-lying states. Progress has been hindered by a scarcity of high quality gas-phase experimental data, while exact ab initio predictions are usually computationally unaffordable due to the large size of the systems. In this work, we present a data set of 34 3d metal-containing complexes with gas-phase ligand-dissociation energies that have reported uncertainties of $\leq$ 2 kcal/mol. We perform all-electron phaseless auxiliary-field quantum Monte Carlo (ph-AFQMC) utilizing multi-determinant trial wavefunctions selected by a blackbox procedure. We compare the results with those from DFT with various functionals, and DLPNO-CCSD(T). We find MAE of 1.09 $\pm$ 0.28 kcal/mol for our best ph-AFQMC method, vs 2.89 kcal/mol for DLPNO-CCSD(T) and 1.57 - 3.87 kcal/mol for DFT. We find maximum errors of 2.96 $\pm$ 1.71 kcal/mol for our best ph-AFQMC method, vs 9.15 kcal/mol for DLPNO-CCSD(T) and 5.98 - 13.69 kcal/mol for DFT. The reasonable performance of several functionals is in stark contrast to the much poorer accuracy previously demonstrated for diatomics, suggesting a moderation in electron correlation due to ligand coordination. However, the unpredictably large errors for a small subset of cases with both DFT and DLPNO-CCSD(T) leave cause for concern, especially due to the unreliability of common multi-reference indicators. In contrast, the robust and, in principle, systematically improvable results of ph-AFQMC for these realistic complexes establish it as a useful tool for elucidating the electronic structure of transition metal-containing complexes and predicting their gas-phase properties.

description: A three-dimensional, space-frequency model for the excitation of electromagnetic radiation in a free-electron laser is presented. The approach is applied in a numerical particle code WB3D, simulating the interaction of a free-electron laser operating in the linear and non-linear regimes. Solution of the electromagnetic excitation equations in the frequency domain inherently takes into account dispersive effects arising from the cavity and the gain medium. Moreover, it facilitates the consideration of statistical features of the electron beam and the excited radiation, necessary for the study of spontaneous emission, synchrotron amplified spontaneous emission (SASE), super-radiance and noise. We employ the code to study the statistical and spectral characteristics of the radiation generated in a pulsed beam free-electron laser operating in the millimeter wavelengths. The evolution of radiation spectrum, excited when a Gaussian shaped bunch with a random distribution of electrons is passing through the wiggler, was investigated.

description: We present programmable two-dimensional arrays of microscopic atomic ensembles consisting of more than 400 sites with nearly uniform filling and small atom number fluctuations. Our approach involves direct projection of light patterns from a digital micromirror device with high spatial resolution onto an optical pancake trap acting as a reservoir. This makes it possible to load large arrays of tweezers in a single step with high occupation numbers and low power requirements per tweezer. Each atomic ensemble is confined to $\sim 1\,μ$m$^3$ with a controllable occupation from 20 to 200 atoms and with (sub)-Poissonian atom number fluctuations. Thus they are ideally suited for quantum simulation and for realizing large arrays of collectively encoded Rydberg-atom qubits for quantum information processing.

description: Amorphous solids such as glass are ubiquitous in our daily life and have found broad applications ranging from window glass and solar cells to telecommunications and transformer cores. However, due to the lack of long-range order, the three-dimensional (3D) atomic structure of amorphous solids have thus far defied any direct experimental determination without model fitting. Here, using a multi-component metallic glass as a proof-of-principle, we advance atomic electron tomography to determine the 3D atomic positions in an amorphous solid for the first time. We quantitatively characterize the short-range order (SRO) and medium-range order (MRO) of the 3D atomic arrangement. We find that although the 3D atomic packing of the SRO is geometrically disordered, some SRO connect with each other to form crystal-like networks and give rise to MRO. We identify four crystal-like MRO networks - face-centred cubic, hexagonal close-packed, body-centered cubic and simple cubic - coexisting in the sample, which show translational but no orientational order. These observations confirm that the 3D atomic structure in some parts of the sample is consistent with the efficient cluster packing model. Looking forward, we anticipate this experiment will open the door to determining the 3D atomic coordinates of various amorphous solids, whose impact on non-crystalline solids may be comparable to the first 3D crystal structure solved by x-ray crystallography over a century ago.

description: (abridged) The Atacama Large Millimeter/submillimeter Array (ALMA) was the top-ranked priority for a new ground-based facility in the 2000 Canadian Long Range Plan. Ten years later, at the time of LRP2010, ALMA construction was well underway, with first science observations anticipated for 2011. In the past 8 years, ALMA has proved itself to be a high-impact, high-demand observatory, with record numbers of proposals submitted to the annual calls and large numbers of highly cited scientific papers across fields from protoplanetary disks to high-redshift galaxies and quasars. The LRP2010 ALMA white paper laid out 8 specific metrics that could be used to judge the success of Canada's participation in ALMA. Among these metrics were publications (number; impact), collaborations (international; multi-wavelength), and student training. To call out one particular metric, Canadians are making excellent use of ALMA in training graduate students and postdocs: as of June 2018, 12 of 23 Canadian first-author papers were led by a graduate student, and a further 4 papers were led by postdocs. All 8 metrics argue for Canada's involvement in ALMA over the past decade to be judged a success. The successful achievement of these wide-ranging goals argues strongly for Canada's continuing participation in ALMA over the next decade and beyond. Looking forward, our community needs to: (1) maintain Canadian access to ALMA and our competitiveness in using ALMA; (2) preserve full Canadian funding for our share of ALMA operations; (3) identify components of ALMA development in which Canada can play a significant role, including stimulating expertise in submillimetre instrumentation to capitalize on future opportunities; and (4) keep Canadians fully trained and engaged in ALMA, as new capabilities become available, reaching the widest possible community of potential users.

description: The entanglement in one-dimensional Anderson model is studied. We show that the pairwise entanglement measured by the average concurrence has a direct relation to the localization length. The numerical study indicates that the disorder significantly reduces the average entanglement, and entanglement distribution clearly displays the entanglement localization. The maximal pairwise entanglement exhibits a maximum as the disorder strength increases,experiencing a transition from increase to decrease. The entanglement between the center of localization and other site decreases exponentially along the spatial direction. Finally,we study effects of disorder on dynamical properties of entanglement.

Making the 'Millennial Middle'

description: In Vancouver, like many other North American cities, there is no housing typology more privileged or more rigorously safeguarded than the detached single-family home. Zoning up to eighty percent of its land for strictly single-family residential districts (RS-1), Vancouver’s single-family homes have been embraced by homeowners and protected by local governments from the ‘intrusion’ of denser development. As a result, 35% of Vancouver’s households occupy 81% of the cities residential land, putting pressure on the other 65% of households to find homes on the remaining 19%. The high demand on the higher density land drives up expensive high-rise condominium developments in the Cities downtown areas. The resulting phenomenon is known as the “Missing middle”; the absence of housing typologies such as duplexes, rowhomes, and courtyard apartments, that serve as middle-ground solutions between high-rise living and single-family homes. Additionally, Vancouver’s current housing stock faces an additional problem, the quintessential nuclear family still serves as the de facto template for a single-family “home”. As the search for housing by Vancouver’s future generations of homeowners and renters increases, so does the gap between their housing options and housing needs. A new template needs to be moulded for the incoming millennial generation – a generations for whom traditional lifestyles are being challenged and living arrangements are increasingly unorthodox. As the reckoning with single-family home zoning sweeps across Vancouver and North America at large, the pressures of housing affordability, housing inequality, climate change and lifestyle change continue to mount. Vancouver has responded by incrementally allowing density into single-family home districts – introducing laneway homes, duplexes, lock-off-suites and most recently the Vancouver City Council voted to permit up to six-unit developments on single-family lots. This graduate project developed two multi-unit strategies for redesigning housing on single-family lots (crica 33’ by 122’) to explore ways Vancouver can increase densification. Ultimately, living in ground-oriented homes will no longer be restricted to the super fortunate and wealthy; now, ground-oriented homes are accessible millennials with an array of family and living dynamics.

description: Web-based, stand-alone datasets offer novice data users a dizzying array of choices before they find the data they're looking for. This presentation will describe the evolution of ProQuest Statistical DataSets, which employs a single interface to access over 630 datasets. Beginning with the three-part screen commonly used in executive information systems, ProQuest and Conquest Systems have altered that interface design to meet the research needs of undergraduates, an effort guided in large part by videotaped sessions with students as they use the product for the first time. The presentation will include screen shots of government dataset sites as well as Statistical DataSets.

description: Rigorous model-based analysis can help inform state-level energy and climate policy. In this study, we utilize an open-source energy system optimization model and publicly available datasets to examine future electricity generation, CO2 emissions, and CO2 abatement costs for the North Carolina electric power sector through 2050. Model scenarios include uncertainty in future fuel prices, a hypothetical CO2 cap, and an extended renewable portfolio standard. Across the modeled scenarios, solar photovoltaics represent the most cost-effective low-carbon technology, while trade-offs among carbon constrained scenarios largely involve natural gas and renewables. We also develop a new method to calculate break-even costs, which indicate the capital costs at which different technologies become cost-effective within the model. Significant variation in break-even costs are observed across different technologies and scenarios. We illustrate how break-even costs can be used to inform the development of an extended renewable portfolio standard in North Carolina. Utilizing the break-even costs to calibrate a tax credit for onshore wind, we find that the resultant wind deployment displaces other renewables, and thus has a negligible effect on CO2 emissions. Such insights can provide crucial guidance to policymakers weighing different policy options. This study provides an analytical framework to conduct similar analyses in other states using an open source model and freely available datasets.

description: We study the phase diagram for two-color QCD in three-dimensional spacetime, as a function of temperature and baryon chemical potential, using the low-energy effective Lagrangian approach. We show one-loop renormalizability at zero temperature, and then use the one-loop effective Lagrangian at finite temperature and chemical potential to show that at low temperature there is a critical line separating the normal and diquark phase, with this critical line ending at a tricritical point. This phase structure is qualitatively similar to that found recently by Splittorff et al for two-color QCD in four-dimensional spacetime, although the details are quite different, due to the different symmetries and the different loop and infrared properties of three-dimensional spacetime.

Dual Development Lines of DDI
Creators: name: Thomas, Wendy
Publisher: name: Zenodo
Year: 2011

description: Since the publication of DDI 3 in 2008, a lot of attention has focused on the expanded features and tools being developed around this new structure. At the same time DDI 2 and earlier versions continue to support the work of data archives worldwide and, with the advent of the IHSN Microdata Toolkit, they also facilitate the collection and management of survey data in many developing and transitional countries. DDI 2 has a stable and growing community of users who will either continue to use this development line or will eventually work in an environment where both DDI development lines are used. In order to support this user base and its evolving needs, DDI 2.5 was developed. This new version adds coverage for features of simple surveys found in DDI 3 and better supports the translation of metadata between the two DDI development lines. DDI 2.5 is backwards-compatible with earlier versions while adding support for new elements and better communication with the DDI 3 structures. This presentation will highlight new features and explore some of the use cases in which DDI 2.5 can benefit the current user community.nbsp;
A possible age-metallicity relation in the Galactic thick disk?

description: A sample of 229 nearby thick disk stars has been used to investigate the existence of an age-metallicity relation (AMR) in the Galactic thick disk. The results indicate that that there is indeed an age-metallicity relation present in the thick disk. By dividing the stellar sample into sub-groups, separated by 0.1 dex in metallicity, we show that the median age decreases by about 5-7 Gyr when going from [Fe/H]=-0.8 to [Fe/H]=-0.1. Combining our results with our newly published alpha-element trends for a local sample of thick disk stars, that show signatures from supernovae type Ia (SNIa), we can here draw the conclusion that the time-scale for the peak of the SNIa rate is of the order 3-4 Gyr in the thick disk. The tentative evidence for a thick disk AMR that we present here also has implications for the thick disk formation scenario; star-formation must have been an ongoing process for several billion years. This is further discussed here and appear to strengthen the hypothesis that the thick disk originates from a merger event with a companion galaxy that puffed up a pre-existing thin disk.

description: In this paper, the late-time optical photometry of supernova (SN) 1993J in M81 from Feburary 1995 to Janurary 2003 is presented. The observations were performed in a set of intermediate-band filters that have the advantage of tracing the strength variations of some spectral features. SN 1993J was found to fade very slowly at late times, declining only by $0.05\pm0.02$ mag 100 d$^{-1}$ in most of the filters from 2 to nearly 10 yrs after discovery. Our data suggest that the circumstellar interaction provides most of the energy to power the late-time optical emission of SN 1993J. This is manifested by several flux peaks seen in the rough spectral energy distributions constructed from the multicolor light curves. The flux peaks near 6600 Å, 5800 Å and 4900 Å may correspond to the emission lines of H$α$, Na I D + He I $λ$5876 and [O III] $λλ$4959, 5007, respectively. The evolution of these emission lines suggest a power-law SN density model as proposed by \citet{cf94}.

 Type species Tamoya quadrumana Müller, 1859.
 Revised diagnosis
Chiropsalmidae with nematocyst warts on the exumbrella; with rounded hump in the pedalial canal bend; with finger­shaped, pendant gastric saccules; with well developed lateral gonads; with tentacles narrow in width and round in cross section; lacking mesenteries.
 Remarks
 The genus Chiropsalmus is herein restricted to include only the former chirodropid species with nematocyst warts on the exumbrellar surface. Chiropsalmus quadrumanus, the type species of the genus, has this distinctive character, as does Chiropsalmus alipes n. sp., described below from the Pacific coast of southern Mexico. This Mexican form is immediately recognizable in having pedalia that more resemble Carybdeida than Chirodropida, i.e., they are long and blade­like, with the branching confined to the very distal end. The enigmatic C. zygonema Haeckel, described from Argentina and not illustrated or observed since, is presumed to belong to this group, because it too has peculiarly blade­like pedalia, although the presence or absence of bell warts was not noted.
