Subjects: subject: High Energy Physics - Theory (hep-th)

description: To endow the N=1* SYM theory with quarks, we embed D7-brane probes into its gravity dual, known as the Polchinski-Strassler background. The non-vanishing 3-form flux G_3 in the background is dual to mass terms for the three adjoint chiral superfields, deforming the N=4 SYM theory to the N=1* SYM theory. We keep its three mass parameters independent. This generalizes our analysis in hep-th/0610276 for the N=2* SYM theory. We work at second order in the mass perturbation, i.e. G_3 and its backreaction on the background are considered perturbatively up to this order. We find analytic solutions for the embeddings which in general depend also on angular variables. We discuss the properties of the solutions and give error estimates on our approximation. By applying the method of holographic renormalization, we show that in all cases the embeddings are at least consistent with supersymmetry.

description: $\cal T$-parity in the Little Higgs model could be violated by anomalies that allow the lightest $\cal T$-odd $A_H$ to decay into $ZZ$ and $W^+W^-$. We analyze these anomaly induced decays and the two-particle and the three-particle decay modes of other heavy quarks and bosons in this model which yield unique Large Hadron Collider (LHC) signals with fully reconstructable events. $\cal T$-odd quarks in the Little Higgs model are nearly degenerate in mass and they decay by almost identical processes; however, members of the heavy Higgs triplet follow distinct decay modes. The branching fractions of three-body decays increase with the global symmetry-breaking energy scale $f$ and are found to be at the level of a few percent in heavy quark decays while they can reach up to 10% for heavy bosons.

description: Motivated by practical applications in heat conduction and contaminant transport, we consider heat and mass diffusion across a perturbed interface separating two finite regions of distinct diffusivity. Under the assumption of continuity of the solution and diffusive flux at the interface, we use perturbation theory to develop an asymptotic expansion of the solution valid for small perturbations. Each term in the asymptotic expansion satisfies an initial-boundary value problem on the unperturbed domain subject to interface conditions depending on the previously determined terms in the asymptotic expansion. Demonstration of the perturbation solution is carried out for a specific, practically-relevant set of initial and boundary conditions with semi-analytical solutions of the initial-boundary value problems developed using standard Laplace transform and eigenfunction expansion techniques. Results for several choices of the perturbed interface confirm the perturbation solution is in good agreement with a standard numerical solution.

Mining in parks : an analysis of the policy framework for B.C.'s provincial parks
Creators: name: Wilson, Norma J.
Publisher: name: University of British Columbia
Year: 2012

description: The provincial parks of British Columbia have endured varying degress of resource exploitation since the creation of the first provincial park in B.C., Strathcona Park in 1911. B.C. Parks, the government agency which manages B.C.'s parks, administers the Park Act (R.S.B.C. 1979 C.309) and derives its dual goals for recreation and conservation from the Act. In addition to the Park Act, there are several levels of policy for B.C. Parks which guide decisions regarding resource use in parks, including "Striking the Balance - B.C. Parks Policy Statement," occasional policy statements in News Releases, and some conditions in resource use permits. This thesis examines the levels of policy which guide decisions regarding mining in parks in British Columbia and the consistency of the commitment to the goals of B.C. Parks through the policy levels. The approach to policy analysis taken is that a policy is both an output of the level above, and an input to the level below. Three criteria are derived from the definitions of policy in the literature. They are that policy should be clear and a guide to decision-making, that it should be forward-looking, and that it should be enforceable. The fourth criterion says that the goals of B.C. Parks stated in the Park Act should be traceable through the policy levels. Since 1973, there have been five policies regarding mining in B.C.'s parks which stand out as significantly altering the commitment of B.C. Parks to its goals. In two of these policies the recreation and conservation goals of B.C. Parks are apparent, while the goals are not apparent in three of the policies. Foreseeable decisions for mining in parks are examined, and the ability of the present policies to guide the decisions is tested. B.C. Parks retains little decision-making authority with respect to mining in parks. On a mineral claim in a recreation area, the Ministry of Energy, Mines and Petroleum Resources has jurisdiction. Off a mineral claim in a recreation area, B.C. Parks has limited authority over mining activities. The fundamental decisions which rests with B.C. Parks is whether or not the recreational values of the area are sufficiently impaired by mining to delete it from the park system. Surprises can occur when the results are different from what was expected, either because the cause is different, the behaviours are not what was anticipated, or an action produces the opposite result from what was intended (Holling 1986: p.294). Several surprises with regard to mining in Parks are imagined and the challenge to the goals of B.C. Parks through the policy levels is examined. A strong commitment to the goals at the upper levels of parks policy, and reflected through the levels is proposed to ensure that B.C.'s parks survive challenges from mining and from other sources.

Lower Metal Enrichment of Virialized Gas in Minihalos
Creators: name: Cen, Renyue

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We differentiate between the metal enrichment of the gas in virialized minihalos and that of the intergalactic medium at high redshift, pertinent to cosmological reionization, with the initial expectation that gas in the high density regions within formed dark matter halos may be more robust thus resistant to mixing with lower density intergalactic medium. Using detailed hydrodynamic simulations of gas clouds in minihalos subject to destructive processes associated with the encompassing intergalactic shocks carrying metal-enriched gas, we find, as an example, that, for realistic shocks of velocities of 10-100km/s, more than (90%,65%) of the high density gas with rho>500 rhob inside a minihalo virialized at z=10 of mass (10^7,10^6)Msun remains at a metallicity lower than 3% of that of the intergalactic medium by redshift z=6. It may be expected that the high density gas in minihalos becomes fuel for subsequent star formation, when they are incorporated into larger halos where efficient atomic cooling can induce gas condensation hence star formation. Since minihalos virialize at high redshift when the universe is not expected to have been significantly reionized, the implication is that gas in virialized minihalos may provide an abundant reservoir of primordial gas to possibly allow for the formation of Population-III metal-free stars to extend to much lower redshift than otherwise expected based on the enrichment of intergalactic medium.

description: Ultracool stellar atmospheres show absorption by alkali resonance lines severely broadened by collisions with neutral perturbers. In the coolest and densest atmospheres, such as those of T dwarfs, Na I and K I broadened by molecular hydrogen and helium can come to dominate the entire optical spectrum. Their profiles have been successfully modelled with accurate interaction potentials in the adiabatic theory, computing line profiles from the first few orders of a density expansion of the autocorrelation function. The line shapes in the emergent spectrum also depend on the distribution of absorbers as a function of depth, which can be modelled with improved accuracy by new models of dust condensation and settling. The far red K I wings of the latest T dwarfs still show missing opacity in these models, a phenomenon similar to what has been found for the Na I line profiles observed in extremely cool, metal-rich white dwarfs. We show that the line profile in both cases is strongly determined by multiple-perturber interactions at short distances and can no longer be reproduced by a density expansion, but requires calculation of the full profile in a unified theory. Including such line profiles in stellar atmosphere codes will further improve models for the coolest and densest dwarfs as well as for the deeper atmosphere layers of substellar objects in general.

Weak and ultrastrong coupling limits of the quantum mean force Gibbs state
Creators: name: Cresser, J. D.

Publisher: name: arXiv
Year: 2021
Subjects: subject: Quantum Physics (quant-ph)

description: The Gibbs state is widely taken to be the equilibrium state of a system in contact with an environment at temperature $T$. However, non-negligible interactions between system and environment can give rise to an altered state. Here we derive general expressions for this mean force Gibbs state, valid for any system that interacts with a bosonic reservoir. First, we derive the state in the weak coupling limit and find that, in general, it maintains coherences with respect to the bare system Hamiltonian. Second, we develop a new expansion method suited to investigate the ultrastrong coupling regime. This allows us to derive the explicit form for the mean force Gibbs state, and we find that it becomes diagonal in the basis set by the system-reservoir interaction instead of the system Hamiltonian. Several examples are discussed including a single qubit, a three-level V-system and two coupled qubits all interacting with bosonic reservoirs. The results shed light on the presence of coherences in the strong coupling regime, and provide key tools for nanoscale thermodynamics investigations.

Terpenoids from the marine sponge Aplysilla glacialis and the nudibranch Cadlina luteomarginata
Creators: name: Tischler, Mark
Publisher: name: University of British Columbia
Year: 2011

description: A chemical study of the pink encrusting sponge Aplysilla glacialis collected in Barkley Sound, B.C., has led to the isolation and structure elucidation of terpenes which are believed to be derived biogenetically from the hypothetical "spongian" precursor. In addition, the first example of a diterpene from a sponge containing a "marginatane" skeleton has been found. Cadlinolide A (75) was isolated and its structure elucidated by a combination of spectroscopic interpretation, chemical degradation, and confirmed by a single crystal x-ray diffraction analysis. The structure of a related metabolite, cadlinolide B (76). was also isolated and elucidated by spectroscopic interpretation and conversion to the known metabolite tetrahydroaplysulphurin-1 (72). The structure of a nor-diterpene, aplysillolide A (101) was determined by spectroscopic interpretation and chemical interconversion along with its dehydrated analogue, aplysillolide B (102). Glaciolide (110). a degraded and highly rearranged diterpene was solved by extensive NMR analysis of both the parent compound and its chemically interconverted derivatives. Glaciolide (110) represents only the second known example of a metabolite containing a "glaciane" skeleton. Marginatone (112) is the first example of a diterpene containing a "marginatane" skeleton from a sponge. The "marginatane" skeleton was first encountered in a metabolite, marginatafuran (111), isolated from the nudibranch Cadlina luteomarginata which is generally found in the same location as Aplysilla glacialis. The structure of cadlinolide C (131), containing both methyl ester and γ lactone moieties, was elucidated by spectroscopic interpretation. This compound is believed to be an isolation artifact Examination of the chemical constituents of the nudibranch Cadlina luteomarginata found feeding on the sponge Aplysilla glacialis yielded a mixture of terpenes mcluding cadlinolide A (75). glaciolide (110) and tetrahydroaplysulphurin-1 (72). Compound 72 was previously isolated from a New Zealand sponge. A review of "spongian" and "marginatane" derived metabolites from sponges and nudibranchs as well as a review of Cadlina luteomarginata terpenoids is presented. [Formulas omitted]
Scaling properties of pyrex and silicon surfaces blasted with sharp particles

description: The blasting of brittle materials with sharp particles is an important fabrication technology in many industrial processes. In particular, for micro-systems, it allows the production of devices with feature sizes down to few tens of microns. An important parameter of this process is the surface roughness of post-blasted surfaces. In this work the scaling properties of Pyrex glass and silicon surfaces after bombardment with alumina particles is investigated. The targets were bombarded at normal incidence using alumina particles with two different average sizes, $29μm$ and $9μm$, respectively. This investigation indicates that the resulting surfaces have multifractal properties. Applying multifractal detrended fluctuation analysis (MFDFA) allowed us to determine the singularity spectrum of the surfaces. This spectrum did not depend on the target material or on the size of the particles. Several parameters quantifying relevant quantities were determined. We argue that for scales below $5 μm$, fracture processes are dominant while at large scales long range correlations are responsible for the multifractal behaviour.

description: The first known case of Coronavirus disease 2019 (COVID-19) was identified in December 2019. It has spread worldwide, leading to an ongoing pandemic, imposed restrictions and costs to many countries. Predicting the number of new cases and deaths during this period can be a useful step in predicting the costs and facilities required in the future. The purpose of this study is to predict new cases and deaths rate one, three and seven-day ahead during the next 100 days. The motivation for predicting every n days (instead of just every day) is the investigation of the possibility of computational cost reduction and still achieving reasonable performance. Such a scenario may be encountered in real-time forecasting of time series. Six different deep learning methods are examined on the data adopted from the WHO website. Three methods are LSTM, Convolutional LSTM, and GRU. The bidirectional extension is then considered for each method to forecast the rate of new cases and new deaths in Australia and Iran countries. This study is novel as it carries out a comprehensive evaluation of the aforementioned three deep learning methods and their bidirectional extensions to perform prediction on COVID-19 new cases and new death rate time series. To the best of our knowledge, this is the first time that Bi-GRU and Bi-Conv-LSTM models are used for prediction on COVID-19 new cases and new deaths time series. The evaluation of the methods is presented in the form of graphs and Friedman statistical test. The results show that the bidirectional models have lower errors than other models. A several error evaluation metrics are presented to compare all models, and finally, the superiority of bidirectional methods is determined. This research could be useful for organisations working against COVID-19 and determining their long-term plans.

description: Scenarios in which right-handed light Standard Model fermions couple to a new gauge group, $U(1)_{T3R}$ can naturally generate a sub-GeV dark matter candidate. But such models necessarily have large couplings to the Standard Model, generally yielding tight experimental constraints. We show that the contributions to $g_μ-2$ from the dark photon and dark Higgs largely cancel out in the narrow window where all the experimental constraints are satisfied, leaving a net correction which is consistent with recent measurements from Fermilab. These models inherently violate lepton universality, and UV completions of these models can include quark flavor violation which can explain $R_{K^{(\ast)}}$ anomalies as observed at the LHCb experiment after satisfying constraints on $Br(B_s\rightarrowμμ)$ and various other constraints in the allowed parameter space of the model. This scenario can be probed by FASER, SeaQuest, SHiP, LHCb, Belle, etc.

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a twin Higgs model based on left-right symmetry with a tree level quartic. This is made possible by extending the symmetry of the model to include two Z_2 parities, each of which is sufficient to protect the Higgs from getting a quadratically divergent mass squared. Although both parities are broken explicitly, the symmetries that protect the Higgs from getting a quadratically divergent mass are broken only collectively. The quadratic divergences of the Higgs mass are thus still protected at one loop. We find that the fine tuning in this model is reduced substantially compared to the original left-right twin Higgs model. This mechanism can also be applied to the mirror twin Higgs model to get a significant reduction of the fine tuning, while keeping the mirror photon massless.

We find that phonon-mediated electron-electron coupling has a large effect on the graphene band structure renormalization, and our analytic theory successfully captures the essential features of the observed graphene electron spectra in the ARPES experiments, predicting a kink at $\sim 200\mathrm{meV}$ below the Fermi level and a reduction of the band velocity by $\sim 10-20%$ at the experimental doping level.

Quantum mechanically, the transition may be described in terms of spectral flow. Gaps in the energy or mass spectrum may become large which effectively truncates the available state space. Using both operator and path integral languages we explicitly discuss examples in quantum mechanics, (light-front) quantum field theory and string theory.

We compute the ground state energy in the presence of probe charges to estimate the potential between them, via adiabatic state preparation. We compare our simulation results and analytical predictions for a finite volume, finding good agreements. In particular our result in the massive case shows a linear behavior for non-integer charges and a non-linear behavior for integer charges, consistently with the expected confinement (screening) behavior for non-integer (integer) charges.

description: The structural properties of BiMn$O_3$ were determined from neutron powder diffraction data as a function of temperature and magnetic field. The structure at all temperatures was found to be centrosymmetric with space group $C2/c$, which is incompatible with ferroelectricity. At T$_C\simeq 100 K$, we observed the onset of a large magnetoelastic strain, proportional to the square of the magnetization. We interpret this structural rearrangement, together with the previously observed magnetodielectric anomalies, as due to the need to optimize the partially frustrated magnetic interactions.

description: We present a simple formalism for parton-shower Markov chains. As a first step towards more complete uncertainty bands, we incorporate a comprehensive exploration of the ambiguities inherent in such calculations. To reduce this uncertainty, we then introduce a matching formalism which allows a generated event sample to simultaneously reproduce any infrared safe distribution calculated at leading or next-to-leading order in perturbation theory, up to sub-leading corrections. To enable a more universal definition of perturbative calculations, we also propose a more general definition of the hadronization cutoff. Finally, we present an implementation of some of these ideas for final-state gluon showers, in a code dubbed VINCIA.

description: Enhanced sampling methods such as metadynamics and umbrella sampling have become essential tools for exploring the configuration space of molecules and materials. At the same time, they have long faced a number of issues such as the inefficiency when dealing with a large number of collective variables (CVs) or systems with high free energy barriers. In this work, we show that with \redc{the clustering and adaptive tuning techniques}, the reinforced dynamics (RiD) scheme can be used to efficiently explore the configuration space and free energy landscapes with a large number of CVs or systems with high free energy barriers. We illustrate this by studying various representative and challenging examples. Firstly we demonstrate the efficiency of adaptive RiD compared with other methods, and construct the 9-dimensional free energy landscape of peptoid trimer which has energy barriers of more than 8 kcal/mol. We then study the folding of the protein chignolin using 18 CVs. In this case, both the folding and unfolding rates are observed to be equal to 4.30~$μs^{-1}$. Finally, we propose a protein structure refinement protocol based on RiD. This protocol allows us to efficiently employ more than 100 CVs for exploring the landscape of protein structures and it gives rise to an overall improvement of 14.6 units over the initial Global Distance Test-High Accuracy (GDT-HA) score.

Originally, the CBT was presented as a non-unitary transformation (a complex canonical transformation in the classical case) that relates two different forms of dynamics in the sense of Dirac. Namely, it maps the asymptotically free form into the harmonically confined form of dynamics associated with the $\mathfrak{so}(2,1)\cong \mathfrak{sl}(2,{\mathbb R})$ conformal symmetry. However, as the transformation relates the non-Hermitian operator $i\hat{D}$, where $\hat{D}$ is the generator of dilations, with the compact Hermitian generator $\hat{\mathcal{J}}_0$ of the $\mathfrak{sl}(2,{\mathbb R})$ algebra, the CBT generator can be associated with a $\mathcal{PT}$-symmetric metric. In this work we review the applications of this transformation for one- and two-dimensional systems, as well as for systems on a cosmic string background, and for a conformally extended charged particle in the field of Dirac monopole. We also compare and unify the CBT with the Darboux transformation. The latter is used to construct $\mathcal{PT}$-symmetric solutions of the equations of the KdV hierarchy with the properties of extreme waves. As a new result, by using a modified CBT we relate the one-dimensional $\mathcal{PT}$-regularized asymptotically free conformal mechanics model with the $\mathcal{PT}$-regularized version of the de Alfaro, Fubini and Furlan system.

A request/response protocol to support ISO remote operations
Creators: name: Goldberg, Murray Warren
Publisher: name: University of British Columbia
Year: 2010

description: The remote operations protocol [X229] is used by one application process to exchange operation information with a remote process. An operation request, with associated parameters, is sent using the Invoke()primitive, and the outcome is returned using the Result(), Error(), or Reject() primitives. ISO defines a stack of protocol layers to support the remote operations protocol. There is redundancy in this stack and services provided by the stack do not closely match the needs of remote operations. Therefore a more suitable supporting protocol is necessary. A supporting protocol must be efficient in terms of association setup and data transfer, must support both interested and disinterested servers, and must provide only the services required by remote operations. Association setup must be efficient as remote operation associations can be numerous and short lived. Interested servers are common, warranting support, though disinterested servers must not suffer the overhead accompanying this support. Several efficient request/response protocols exist capable of supporting remote operations, though each has disadvantages. This thesis defines a request/response protocol, RRP, which satisfies the criteria above. RRP requires no separate PDU transfer to establish or release an association. Data transfer is efficient in terms of network utilization, unnecessary retransmissions and acknowledgements. RRP assumes an unsequenced, unreliable, and error prone datagram service. RRP provides a reliable, sequenced, synchronous request/response service. RRP provides optional peer process monitoring for interested servers.

description: A new technique is demonstrated for carrying out exact positive-P phase-space simulations of the coherent Ising machine quantum computer. By suitable design of the coupling matrix, general hard optimization problems can be solved. Here, computational quantum simulations of a feedback type of photonic parametric network are carried out, which is the implementation of the coherent Ising machine. Results for success rates are obtained using this scalable phase-space algorithm for quantum simulations of quantum feedback devices.

description: Semiclassical calculations using the Herman-Kluk initial value treatment are performed to determine energy eigenvalues of bound and resonance states of the collinear helium atom. Both the $eZe$ configuration (where the classical motion is fully chaotic) and the $Zee$ configuration (where the classical dynamics is nearly integrable) are treated. The classical motion is regularized to remove singularities that occur when the electrons collide with the nucleus. Very good agreement is obtained with quantum energies for bound and resonance states calculated by the complex rotation method.

description: We study entanglement-assisted quantum error-correcting codes (EAQECCs) arising from classical one-point algebraic geometry codes from the Hermitian curve with respect to the Hermitian inner product. Their only unknown parameter is $c$, the number of required maximally entangled quantum states since the Hermitian dual of an AG code is unknown. In this article, we present an efficient algorithmic approach for computing $c$ for this family of EAQECCs. As a result, this algorithm allows us to provide EAQECCs with excellent parameters over any field size.

description: We couple a recently-established N=1 globally supersymmetric self-dual Yang-Mills multiplet in three dimensions to supergravity. This becomes possible due to our previous result on globally supersymmetric formulation based on a compensator multiplet. We further couple the self-dual vector to a supersymmetric sigma-model on the coset SO(8,n) / SO(8) X SO(n) via minimal couplings for an arbitrary gauged subgroup H_0 \subset SO(8) X SO(n). A corresponding superspace formulation is also presented.

Issues on design and implementation of protocol test systems
Creators: name: Lee, Bernard P.
Publisher: name: University of British Columbia
Year: 2010

description: The advant of Open Systems Interconnection (OSI) accentuates the importance of conformance testing of protocol implementations. Before a protocol implementation is delivered for conformance testing, it often has to go through several iterations of diagnostic testing. This thesis discusses various issues that arise in the design and implementation of protocol test systems for conformance and diagnostic testing. Issues discussed in this thesis include test system implementation decisions, test management, test development environment and tools, test languages, encoding and decoding, PDU specification and storage, and portability problems. The experience of testing different protocol implementations on three different environments are also discussed.

description: This paper is concerned with a stochastic linear-quadratic (LQ) optimal control problem on infinite time horizon, with regime switching, random coefficients, and cone control constraint. To tackle the problem, two new extended stochastic Riccati equations (ESREs) on infinite time horizon are introduced. The existence of the nonnegative solutions, in both standard and singular cases, is proved through a sequence of ESREs on finite time horizon. Based on this result and some approximation techniques, we obtain the optimal state feedback control and optimal value for the stochastic LQ problem explicitly. Finally, we apply these results to solve a lifetime portfolio selection problem of tracking a given wealth level with regime switching and portfolio constraint.

Final spin of a coalescing black-hole binary: an Effective-One-Body approach

description: We update the analytical estimate of the final spin of a coalescing black-hole binary derived within the Effective-One-Body (EOB) approach. We consider unequal-mass non-spinning black-hole binaries. It is found that a more complete account of relevant physical effects (higher post-Newtonian accuracy, ringdown losses) allows the {\it analytical} EOB estimate to `converge towards' the recently obtained {\it numerical} results within 2%. This agreement illustrates the ability of the EOB approach to capture the essential physics of coalescing black-hole binaries. Our analytical approach allows one to estimate the final spin of the black hole formed by coalescing binaries in a mass range ($ν=m_1m_2/(m_1+m_2)^2 < 0.16 $) which is not presently covered by numerical simulations.

Relativistic massive particle with spin-1/2, a vector bundle point of view

description: Recently, in the context of Relativistic Quantum Information Theory (RQI) of massive spin-1/2 particles, it has been suggested that it is impossible to perform a momentum-independent spin measurement, showing the inadequacy of the spin reduced density matrix as a legitimate information resource. This is because there is an unavoidable ambiguity in the definition of the spin of a moving particle. In this paper, by introducing a vector bundle theoretic way to view the single-particle state space, we try to rule out this ambiguity. The discrete degree of freedom of the resulting representation space contains information about the Pauli-Lubansky four-vector of the particle instead of the ambiguous spin. Comparing this representation with the standard one used in the RQI literature, we show that the discrete degree of freedom of the standard representation space attains the meaning of the Newton-Wigner spin. Also using this viewpoint, we give a mathematical proof of why the spin reduced density matrix is meaningless, which is stronger than the previous claims in that it asserts that the matrix is void of any meaning at all, not just in terms of the impossibility of measurement or Lorentz non-covariance. We give a way (which turns out to be the only way) to modify it to obtain the Pauli-Lubansky reduced density matrix, which is covariant under Lorentz transformations.
