description: We present the results of a 400ks Chandra survey of 29 extended Ly-alpha emitting nebulae (Ly-alpha Blobs, LABs) in the z=3.09 proto-cluster in the SSA22 field. We detect luminous X-ray counterparts in five LABs, implying a large fraction of active galactic nuclei (AGN) in LABs, f_AGN = 17% down to L_2-32keV ~ 10^44 erg/s. All of the AGN appear to be heavily obscured, with spectral indices implying obscuring column densities of N_H > 10^23 cm^-2. The AGN fraction should be considered a lower limit, since several more LABs not detected with Chandra show AGN signatures in their mid-infrared emission. We show that the UV luminosities of the AGN are easily capable of powering the extended Ly-alpha emission via photo-ionization alone. When combined with the UV flux from a starburst component, and energy deposited by mechanical feedback, we demonstrate that 'heating' by a central source, rather than gravitational cooling is the most likely power source of LABs. We argue that all LABs could be powered in this manner, but that the luminous host galaxies are often just below the sensitivity limits of current instrumentation, or are heavily obscured. No individual LABs show evidence for extended X-ray emission, and a stack equivalent to a >9Ms exposure of an average LAB also yields no statistical detection of a diffuse X-ray component. The resulting diffuse X-ray/Ly-alpha luminosity limit implies there is no hot (T>10^7 K) gas component in these halos, and also rules out inverse Compton scattering of cosmic microwave background photons, or local far-infrared photons, as a viable power source for LABs.

description: An increasing number of experiments at the Belle, BNL, CERN, DAΦNE and SLAC accelerators are confirming the violation of time reversal invariance (T). The violation signifies a fundamental asymmetry between the past and future and calls for a major shift in the way we think about time. Here we show that processes which violate T symmetry induce destructive interference between different paths that the universe can take through time. The interference eliminates all paths except for two that represent continuously forwards and continuously backwards time evolution. Evidence from the accelerator experiments indicates which path the universe is effectively following. This work may provide fresh insight into the long-standing problem of modeling the dynamics of T violation processes. It suggests that T violation has previously unknown, large-scale physical effects and that these effects underlie the origin of the unidirectionality of time. It may have implications for the Wheeler-DeWitt equation of canonical quantum gravity. Finally it provides a view of the quantum nature of time itself.

description: The complex structure of the light curves of Swift GRBs has made their interpretation and that of the blast wave caused by the burst, more difficult than in the pre-Swift era. We aim to constrain the blast wave parameters: electron energy distribution, p, density profile of the circumburst medium, k, and the continued energy injection index, q. We do so by comparing the observed multi-wavelength light curves and X-ray spectra of a Swift sample to the predictions of the blast wave model. We can successfully interpret all of the bursts in our sample of 10, except two, within the framework of the blast wave model, and we can estimate with confidence the electron energy distribution index for 6 of the sample. Furthermore we identify jet breaks in half of the bursts. A statistical analysis of the distribution of p reveals that, even in the most conservative case of least scatter, the values are not consistent with a single, universal value. The values of k suggest that the circumburst density profiles are not drawn from only one of the constant density or wind-like media populations.

Stability relationships for cis-trans olefin pairs
Creators: name: Page, Brian Denis
Publisher: name: University of British Columbia
Year: 2011

description: An investigation was undertaken to examine some of the factors which may affect the thermodynamic position of equilibrium for a number of cis-trans olefin pairs. The positions of equilibrium were measured for selected aldehydes, ketones, nitriles and propenyl ethers. For these unsaturated compounds it has been found that their position of equilibrium may be attributed to four different factors. These factors are: i) a steric factor involving van der Waals repulsion between cis groups; ii) a polar repulsive term involving electrostatic repulsion between polar groups; iii) an effect termed differential resonance stabilization, which results from a conjugative stabilization by resonance which is greater in the trans isomer than in the cis isomer, where steric distortion from coplanarity of the carbonyl group and the double bond is present; and iv) an attractive interaction arising between cis substituents. The previously unreported Z isomers of crotonaldehyde and tiglaldehyde have been prepared as a mixture with the E isomers by photoisomerization of the E isomers. The presence of the Z isomers was readily detected by n.m.r. spectroscopy. Several β-halo α, β-unsaturated aldehydes have been prepared. The differential resonance stabilization, which resulted in >98% of the E isomer in the crotonaldehyde and tiglaldehyde equilibrium, was found to be partially compensated by an additional halogen-formyl polar repulsive term. The replacement of the β-methyl group in β-chlorocrotonaldehyde by a tert-butyl group increased the differential resonance stabilization effect such that the presence of the E isomer in the equilibrium was not detected. The effect of this tert-butyl group is partially compensated by the replacement of the β-halogen by methoxyl. The equilibrium positions for the series of aldehydes were compared to those of the corresponding ketones and esters. The preferential stabilization of a more polar isomer of a given isomer pair by a polar solvent has been investigated for several nitriles and haloölefins. The magnitude of the solvent stabilization effect in the above compounds was found to depend on the difference in polarity of the two solvents and the difference in polarity of the isomeric pair. With the above information, it was possible to extend the work of Gardner and McGreer on the additivity of free energy terms (multiplication of equilibrium ratios) to predict olefinic equilibria. In most cases correlation of the equilibrium ratio to a non-polar solvent, gave reasonable agreement between the predicted and experimental positions of equilibrium.

description: We investigate the role of Casimir energy as a mechanism for brane stability in five-dimensional models with the fifth dimension compactified on an S^1\Z_2 orbifold, which includes the Randall-Sundrum two brane model (RS1). We employ a zeta-function regularization technique utilizing the Schwinger proper time method and the Jacobi theta function identity to calculate the one-loop effective potential. We show that the combination of the Casimir energies of a scalar Higgs field, the three generations of Standard Model fermions and one additional massive non-SM scalar in the bulk produce a non-trivial minimum of the potential. In particular, we consider a scalar field with a coupling in the bulk to a Lorentz violating vector particle localized to the compactified dimension. Such a scalar may provide a natural means of the fine-tuning needed for stabilization of the brane spearation. Lastly, we briefly review the possibility that Casimir energy plays a role in generating the currently observed epoch of cosmological inflation by examining a simple five-dimensional anisotropic metric.

Besides scheduled observations, so far MAGIC succeeded in discovering TeV gamma rays from three blazars following triggers from high optical states. I report selected highlights from recent MAGIC observations of extragalactic TeV gamma-ray sources, emphasizing and discussing the new physics insights the MAGIC observations were able to contribute.

description: In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal quantum simulator would be controllable, and built using existing technology. In some cases, moving away from gate-model-based implementations of quantum computing may offer a more feasible solution for particular experimental implementations. Here we consider an adiabatic quantum simulator which simulates the ground state properties of sparse Hamiltonians consisting of one- and two-local interaction terms, using sparse Hamiltonians with at most three-local interactions. Properties of such Hamiltonians can be well approximated with Hamiltonians containing only two-local terms. The register holding the simulated ground state is brought adiabatically into interaction with a probe qubit, followed by a single diabatic gate operation on the probe which then undergoes free evolution until measured. This allows one to recover e.g. the ground state energy of the Hamiltonian being simulated. Given a ground state, this scheme can be used to verify the QMA-complete problem LOCAL HAMILTONIAN, and is therefore likely more powerful than classical computing.

description: We develop a discrete analogue of Hamilton-Jacobi theory in the framework of discrete Hamiltonian mechanics. The resulting discrete Hamilton-Jacobi equation is discrete only in time. We describe a discrete analogue of Jacobi's solution and also prove a discrete version of the geometric Hamilton-Jacobi theorem. The theory applied to discrete linear Hamiltonian systems yields the discrete Riccati equation as a special case of the discrete Hamilton-Jacobi equation. We also apply the theory to discrete optimal control problems, and recover some well-known results, such as the Bellman equation (discrete-time HJB equation) of dynamic programming and its relation to the costate variable in the Pontryagin maximum principle. This relationship between the discrete Hamilton-Jacobi equation and Bellman equation is exploited to derive a generalized form of the Bellman equation that has controls at internal stages.

description: A simple Sweet--Parker-like model for the electron current layer in resistive Hall magnetohydrodynamic (MHD) reconnection is presented, with the focus on the collisionless limit. The derivation readily recovers the main results obtained recently by Malyshkin [PRL, 101, 225001 (2008)] and others, but is much quicker and more physically transparent. In particular, it highlights the role of resistive drag in determining the electron outflow velocity. The principal limitations of any such approach are discussed.

description: The constraints on the time variation of the fine structure constant at recombination epoch relative to its present value, $Δα/α\equiv (α_{\mathrm{rec}} - α_{\mathrm{now}})/α_{\mathrm{now}}$, are obtained from the analysis of the 5-year WMAP cosmic microwave background data. As a result of Markov-Chain Monte-Carlo analysis, it is found that, contrary to the analysis based on the previous WMAP data, the mean value of $Δα/α=-0.0009$ does not change significantly whether we use the Hubble Space Telescope (HST) measurement of the Hubble parameter as a prior or not. The resultant 95% confidence ranges of $Δα/α$ are $-0.028 < Δα/α< 0.026$ with HST prior and $-0.050 < Δα/α< 0.042$ without HST prior.

title: The Relationship Between Adolescents' Use of Internet-enabled Mobile Devices and Engaging in Problematic Digital Behaviors
Creators: name: Atwood, Ryan
Publisher: name: Utah State University
Year: 2016

description: The purpose of this study was to examine the relationship between teenagers’ use of mobile Internet devices and their involvement in risky digital behaviors, including problematic Internet use, exposure to pornography, and participation in sexting. A crosssectional correlational design using a sample (N = 97) of teens aged 13-18 was used.
Linear regression analyses revealed that teens using smartphones as their primary source of Internet access were most likely to receive sexting requests, while teens using computers to access the Internet were most likely to intentionally view pornography. Additionally, teens who used multiple mobile devices to connect to the Internet and teens who had owned at least one mobile Internet device for longer periods of time were most likely to have higher levels of problematic Internet use.
Contextual factors such as age, gender, family structure, religious commitment, attachment to parents, and parental monitoring of online activities were also examined to determine their relationship to the aforementioned outcomes. Consistent with adolescent developmental trajectories, older teens reported higher rates of pornography exposure and sexting requests, and indicated a greater willingness to participate in sexting. However, younger teens who used smartphones as their primary source of Internet access were just as likely as older teens to have received requests to sext. Males had higher rates of pornography exposure and were more willing than females to send sexual messages to their significant other. Females, on other hand, were asked to sext more frequently. Teens with high levels of religious commitment had the lowest levels of pornography exposure and participation in sexting.
Among the parental variables examined, teens’ attachment to their parents was most significantly related to the studies’ outcomes. Strongly attached teens had lower levels of problematic Internet use, pornography exposure, and participation in sexting than their peers who were not as strongly attached to their parents.
Reaction of rhodium III chlorides with ethylene in aqueous HC1 solution.
Creators: name: Kastner, Michael Robin
Publisher: name: University of British Columbia
Year: 2011

description: In the presence of iron (III) and other oxidants, HCl solutions of RhCl₃.3H₂O under mild conditions catalyze the oxidation of ethylene to acetaldehyde. The kinetics of the reaction measured by gas-uptake techniques indicate the presence of both ethylene dependent and independent steps. Hydroxy species such as RhCl₅(OH)³ ̄and RhCl₄(OH) (H₂O)² ̄, although present in very small concentrations, are significantly reactive towards ethylene. A mechanism based on that postulated for a similar Pd(II) system is presented. This involves the rearrangement of a rhodium (III) hydroxy π - ethylene complex to a σ - complex, followed by the production of acetaldehyde and rhodium (I). However, unlike in the Pd(II) system where the rate determining step is the conversion of the π - to σ-C₂H₄ complex, the rate determining step in the Rh(III) system is thought to involve the production of the π- complex. Iron (III) oxidizes Rh(I) back to Rh(III), giving the net reaction: C₄H₄ + H₂O + 2Fe(III) Rh(III) ⇥ CH₃CHO + 2H+ + 2Fe(II)

description: We discuss the finite size behavior of the adiabatic Dicke model, describing the collective coupling of a set of N-two level atoms (qubits) to a faster (electromagnetic) oscillator mode. The energy eigen-states of this system are shown to be directly related to those of another widely studied collective spin model, the uniaxial one. By employing an approximate continuum approach, we obtain a complete characterization of the properties of the latter, which we then use to evaluate the scaling properties of various observables for the original Dicke model near its quantum phase transition.

Safety risk management for railroad human factors: case studies on restricted-speed accident and trespassing
Creators: name: Zhang, Zhipeng
Publisher: name: No Publisher Supplied
Year: 2020

description: Railroads play a key role in the transportation infrastructure and economic development of the United States, and safety is of the utmost importance. Railroad safety is mainly affected by infrastructure, rolling stock, and human factors. Over the past decade, relatively less research has been undertaken to mitigate the human-factor-caused railroad incident risk despite considerable efforts and improvements in the infrastructure and rolling stock. The human errors in railroads may result in injuries or fatalities, infrastructure and rolling stock damages, and environmental impacts. This dissertation presents a methodological framework for railroad human-factor-caused safety risk management that encompasses risk assessment and mitigation. First, accident/incident data and information should be collected and used to identify safety risks, undesired human factor-related events, and risk management objectives. Second, risk assessment should be conducted to evaluate safety risks and contributing factors. The third step is to develop and evaluate effective risk mitigation strategies based on the risk analysis results. The proposed safety risk management framework is applied to two human-factor-caused risk scenarios: restricted-speed train accidents and trespassing events, both of which collectively constitute over 95% of all rail-related fatalities. First, in terms of restricted-speed safety research, the dissertation consists of a collection of historical restricted-speed train accidents, quantitative and qualitative safety risk analysis, PTC-based accident risk mitigation with a proposed Concept of Operations, and a Monte Carlo simulation-based quantitative assessment of mitigation strategies. Second, in terms of trespassing research, the dissertation focuses on Artificial-Intelligence-aided trespassing data detection and location-specific trespassing data analysis, as well as specific trespassing safety strategies and proactive risk management.
Supersymmetric Wilson Loops in Diverse Dimensions

description: We consider supersymmetric Wilson loops a la Zarembo in planar supersymmetric Yang-Mills theories in diverse dimensions. Using perturbation theory we show that these loops have trivial vacuum expectation values to second order in the 't Hooft coupling. We review the known superspace results which, for specific dimensions, extend this triviality to all orders in the 't Hooft coupling. Using the gauge/gravity correspondence, we construct the explicit dual fundamental string solutions corresponding to these Wilson loops for the case of circular geometry. We find that the regularized action of these string solutions vanishes. We also generalize the framework of calibrated surfaces to prove the vanishing of the regularized action for loops of general geometry. We propose a possible string-side manifestation of the gauge theory generalized Konishi anomaly in seven dimensions.

Synthetic applications of dishcargegenerated singlet oxygen
Creators: name: Ouchi, M. Dennis,
Publisher: name: University of British Columbia
Year: 2011

description: The electric discharge method of generating, singlet-molecular oxygen was demonstrated to be a useful technique for preparative scale oxygenations of suitable organic substrates. Representative examples of known singlet oxygen acceptors were exposed to discharge-generated singlet oxygen while dissolved in organic solvents at -78⁰ or adsorbed onto solid supports at room temperature. Typical oxygenation products were obtained in generally good yields. The various known methods of generating singlet molecular oxygen and the relative advantages and disadvantages of the electric discharge method are-discussed. Adsorption of substrates onto solid surfaces appears to have no effect on the course of the addition of singlet oxygen to the organic moiety. The success of this technique is perhaps due to the increase in the surface area of contact between the substrate and singlet oxygen.. Exploratory oxygenations of l,⁴-dienes and epoxides adsorbed onto solid surfaces were all unsuccessful.

description: Complex formalism of Riemann - Silberstein - Majorana - Oppenheimer in Maxwell electrodynamics is extended to the case of arbitrary pseudo-Riemannian space - time in accordance with the tetrad recipe of Tetrode - Weyl - Fock - Ivanenko. In this approach, the Maxwell equations are solved exactly on the background of static cosmological Einstein model, parameterized by special cylindrical coordinates and realized as a Riemann space of constant positive curvature. A discrete frequency spectrum for electromagnetic modes depending on the curvature radius of space and three parameters is found, and corresponding basis electromagnetic solutions have been constructed explicitly. In the case of elliptical model a part of the constructed solutions should be rejected by continuity considerations. Similar treatment is given for Maxwell equations in hyperbolic Lobachevsky model, the complete basis of electromagnetic solutions in corresponding cylindrical coordinates has been constructed as well, no quantization of frequencies of electromagnetic modes arises.

description: This brief working paper provides an initial overview of the CoreTrustSeal Requirements with regard to their broader applicability to data and metadata services beyond Trustworthy Digital Repositories (TDR). Some concluding remarks provide a first outline of the functional components of trustworthy data services based on our initial analysis. With the exceptions of “Preservation Plan” and “ReUse” our assessment is that all of the CoreTrustSeal Requirements are applicable to any (meta)data service or (meta)data service component or function. This is a first step in an internal planning and analysis process by the UK Data Service. It is shared in the interests of transparency and to provide a reference point for some engagement with peers on this topic. This version is a draft and should not be considered as final.

description: We study decoherence induced by a dynamic environment undergoing a quantum phase transition. Environment's susceptibility to perturbations - and, consequently, efficiency of decoherence - is amplified near a critical point. Over and above this near-critical susceptibility increase, we show that decoherence is dramatically enhanced by non-equilibrium critical dynamics of the environment. We derive a simple expression relating decoherence to the universal critical exponents exhibiting deep connections with the theory of topological defect creation in non-equilibrium phase transitions.

description: We give a detailed discussion of optimal quantum states for optical two-mode interferometry in the presence of photon losses. We derive analytical formulae for the precision of phase estimation obtainable using quantum states of light with a definite photon number and prove that maximization of the precision is a convex optimization problem. The corresponding optimal precision, i.e. the lowest possible uncertainty, is shown to beat the standard quantum limit thus outperforming classical interferometry. Furthermore, we discuss more general inputs: states with indefinite photon number and states with photons distributed between distinguishable time bins. We prove that neither of these is helpful in improving phase estimation precision.

Hanbury Brown and Twiss Correlations of Cooper Pairs in Helical Liquids
Creators: name: Choi, Mahn-Soo
Publisher: name: arXiv
Year: 2010
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We propose a Hanbury Brown and Twiss (HBT) experiment of Cooper pairs on the edge channels of quantum spin Hall insulators. The helical edge channels provide a well defined beam of Cooper pairs and perfect Andreev reflections from superconductors. Surprisingly, the Cooper pairs do not bear a bosonic nature at all once emitted from the superconductor, and the cross correlation is strongly negative as for free electrons. This result is counter-intuitive, and seemingly contradictory to the previous theoretical and recent experimental results. We will point out that our setup is much closer in spirit to the original HBT experiment (and different) than those in previous works. We will argue that these differences affect significantly the results.

Development and applications of multi-layered genetic algorithms to multi-dimensional optimisation problems
Creators: name: Kelareva, Galina Vladislavovna
Publisher: name: University Of Tasmania
Year: 2023

description: Genetic algorithms represent a global optimisation method, imitating the principles of natural evolution: selection and survival of the fittest. Genetic algorithms operate on a randomly initialised population of potential solutions to a problem. The solutions develop by passing valuable genetic information to succeeding generations. Genetic algorithms are known as a robust technique suitable for a variety of optimisation problems. However, when applied to complex combinatorial problems with multiple parameters, conventional genetic algorithms are usually slow and ineffective due to the large search space. This thesis proposes a novel approach to the development of a genetic algorithm and applies this approach to a maintenance scheduling problem in a power generation system. Problem specific knowledge is utilised to divide the problem into several layers, with each layer representing a part of the initial problem. Solutions are progressively developed, with each layer algorithm finding partial solutions that satisfy specified criteria. These partial solutions are then used as building blocks in the next layer, to progressively build up complete solutions. The resulting multi-layered genetic algorithm is able to concentrate its search efforts in areas where good quality solutions are likely to be present, therefore producing better results than traditional genetic algorithms. Further developments of the multi-layered genetic algorithm are also suggested in this thesis. The algorithm is combined with a local search method, and heuristic rules are used for initialisation of the population. The combined method results in an effective and fast exploration of the problem's search space and is suitable for a variety of optimisation problems. The proposed algorithm is implemented using MATLAB programming language and tested on a real power generation system. A number of implementation issues, such as specific chromosome structure and a varying generation gap; interchangeable solutions and gene convergence; weeding out duplicates from the population and reducing the search space without losing the quality of representing the problem domain, are all discussed. Specifics of a local search method and its representation are also examined. Special attention is paid to developing efficient evaluation and neighbourhood exploration procedures.
Derivation of sensitivity of a Geiger mode APDs detector from a given efficiency for QKD experiments

description: The detection sensitivity (DS) of the commercial single-photon-receiver based on InGaAs gate-mode avalanche photodiode is estimated. Instalment of a digital-blanking-system (DBS) to reduce dark current makes the difference between DS, which is an efficiency of the detector during its open-gate/active state, and the total/overall detection efficiency (DE). By numerical simulations, it is found that the average number of light-pulses, blanked by DBS, following a registered pulse is 0.333. DS is estimated at 0.216, which can be used for estimating DE for an arbitrary photon arriving rate and a gating frequency of the receiver.
