description: We experimentally studied the effect of positional disorder on a Josephson junction array with $f = n$, ${1/2} + n$, or ${2/5} + n$ flux quanta per unit cell for integral $n$. This system provides an experimental realization of a two-dimensional XY model with random phase shifts. Contrary to many earlier numerical and analytical investigations, our results suggest that low-temperature superconductivity is never destroyed by positional disorder. As the disorder strength increased, the Kosterltz-Thouless (KT) type order in the $f = 0$ and 1/2 systems changed to a non-KT type order with a long-range phase coherence, which persisted even in the maximal disorder limit. A possible finite-temperature glass transition is discussed.

description: We show that heavy axion domain walls induce domain walls of the QCD axion through a mixing between the heavy axion and the QCD axion, even when the pre-inflationary initial condition is assumed for the QCD axion. The induced domain walls arise because the effective $θ$ parameter changes across the heavy axion domain walls, shifting the potential minimum of the QCD axion. When the heavy axion domain walls collapse, the induced QCD axion domain walls collapse as well. This novel mechanism for producing the QCD axions can explain dark matter even with the axion decay constant as small as ${\cal O}(10^{9})$ GeV. In particular, this scenario requires domain wall collapse near the QCD crossover, potentially accounting for the stochastic gravitational wave background suggested by recent pulsar timing array observations, including NANOGrav. Using this mechanism, it is also possible to easily create induced domain walls for string axions or axions with a large decay constant, which would otherwise be challenging. We also comment on the implications for cosmic birefringence using induced axion domain walls.

Noncoherent detection for differential offset QPSK
Creators: name: Ho, Ivan Chit Hin
Publisher: name: University of British Columbia
Year: 2009

description: At the physical layer of wireless communication systems, differential offset quaternary phase-shift keying (DOQPSK) offers a great avenue for low-cost implementation. However, its unfavorable error performance with conventional differential detection (DD) has made DOQPSK unpopular in practical use. Recently, Dr. M. Simon proposed a multiple-bit differential detection (MBDD) scheme that is derived from optimal maximum-likelihood block detection (MLBD) [1]. Asymptotically, MBDD still suffers a 3 dB loss in power efficiency compared to that of coherent detection (CD). To close the performance gap between MBDD and CD, and to make the receiver a simple and versatile solution, five novel noncoherent receiver designs for DOQPSK are proposed in this thesis: full-size MBDD (F-MBDD), improved MBDD (I-MBDD), noncoherent linear equalization (NLE), noncoherent decision-feedback equalization (NDFE), and noncoherent sequence estimation (NSE). In F-MBDD, we use an appropriate model for the overall channel to overcome the performance gap of Simon's receiver. I-MBDD improves the slow convergence of the error value in F-MBDD by truncating the detection window size from N — 1 to N — 3. For NLE and NDFE, computational complexity is reduced by employing suboptimal equalization techniques to suppress inter-symbol interference (ISI) introduced by the OQPSK modulation. Finally, NSE uses ML detection with a trellis decoder that is based on the Viterbi algorithm (VA). When designed carefully, all the schemes proposed in this work have shown performances close to that of CD. In addition, receiver parameters can be controlled to balance performance, complexity, and versatility.

description: The Levin-Wen model of string-net condensation explains how topological phases emerge from the microscopic degrees of freedom of a physical system. However, the original construction is not applicable to all unitary fusion category since some additional symmetries for the $F$-symbols are imposed. In particular, the so-called tetrahedral symmetry is not fulfilled by many interesting unitary fusion categories. In this paper, we present a generalized construction of the Levin-Wen model for arbitrary multiplicity-free unitary fusion categories that works without requiring these additional symmetries. We explicitly calculate the matrix elements of the Hamiltonian and, furthermore, show that it has the same properties as the original one.

Microscopic Description of Black Rings in AdS/CFT

description: We discuss some aspects of the recently discovered BPS black ring solutions in terms of the AdS/CFT correspondence. In the type IIB frame in which the black ring carries the charges of the D1-D5-P system, we propose a microscopic description of the rings in the orbifold CFT governing this system. In our proposal, the CFT effectively splits into two parts: one part captures the supertube-like properties of the ring, and the other captures the entropy. We can also understand the black ring entropy by relating the geometry near the ring to BPS black holes in four dimensions, although this latter approach does not directly lead to an identification of black rings in terms of the D1-D5-P CFT.

description: Organic light emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) utilize molecular systems with a small energy splitting between singlet and triplet states. This can either be realized in intramolecular charge transfer states of molecules with near-orthogonal donor and acceptor moieties or in intermolecular exciplex states formed between a suitable combination of individual donor and acceptor materials. Here, we investigate 4,4'-(9H,9'H-[3,3'-bicarbazole]-9,9'-diyl)bis(3-(trifluoromethyl) benzonitrile) (pCNBCzoCF3), which shows intramolecular TADF but can also form exciplex states in combination with 4,4',4''-tris[phenyl(m-tolyl)amino]triphenylamine (m-MTDATA). Orange emitting exciplex-based OLEDs additionally generate a sky-blue emission from the intramolecular emitter with an intensity that can be voltage-controlled. We apply electroluminescence detected magnetic resonance (ELDMR) to study the thermally activated spin-dependent triplet to singlet up-conversion in operating devices. Thereby, we can investigate intermediate excited states involved in OLED operation and derive the corresponding activation energy for both, intra- and intermolecular based TADF. Furthermore, we give a lower estimate for the extent of the triplet wavefunction to be >1.2 nm. Photoluminescence detected magnetic resonance (PLDMR) reveals the population of molecular triplets in optically excited thin films. Overall, our findings allow us to draw a comprehensive picture of the spin-dependent emission from intra- and intermolecular TADF OLEDs.

description: With antenna spacing much less than half a wavelength in confined space, holographic multiple-input multiple-output (HMIMO) technology presents a promising frontier in next-generation mobile communication. We delve into the research of the multi-user uplink transmission with both the base station and the users equipped with holographic planar arrays. To begin, we construct an HMIMO channel model utilizing electromagnetic field equations, accompanied by a colored noise model that accounts for both electromagnetic interference and hardware noise. Since this model is continuous, we approximate it within a finite-dimensional space spanned by Fourier space series, which can be defined as the communication mode functions. We show that this channel model samples Green's function in the wavenumber domain in different communication modes. Subsequently, we tackle the challenging task of maximizing the spectral efficiency (SE) of the system, which involves optimizing the continuous current density function (CDF) for each user. Using the aforementioned approximation model, we transform the optimization variables into expansion coefficients of the CDFs on a finite-dimensional space, for which we propose an iterative water-filling algorithm. Simulation results illustrate the efficacy of the proposed algorithm in enhancing the system SE and show the influence of the colored noise and the system parameters on the SE.

In a model independent analysis, the pattern of deviations can be used to probe which Wilson coefficients get a significant contribution from the new physics. We demonstrate this idea using several well-motivated models of new physics, and apply it to current data.

description: Microwave-driven trapped ion logic gates offer a promising avenue for advancing beyond laser-based logic operations. In future microwave-based operations, however, the joule heat produced by large microwave currents flowing through narrow microwave electrodes would potentially hinder improvements in gate speed and fidelity. Moreover, scalability, particularly in cryogenic trapped ion systems, is impeded by the excessive joule heat. To address these challenges, we present a novel approach: superconducting surface trap chips that integrate high-$Q$ microwave resonators with large current capacities. Utilizing sub-ampere microwave currents in superconducting Nb resonators, we generate substantial magnetic field gradients with significantly reduced losses compared to conventional metal chips. By harnessing the high $Q$ factors of superconducting resonators, we propose a power-efficient two-qubit gate scheme capable of achieving a sub-milliwatt external microwave input power at a gate Rabi frequency of 1 kHz.

description: The rapid recent appreciation of the Kwacha has placed these gains at risk. The sudden strengthening of the Kwacha since November 2005 has reduced the Kwacha value of agricultural exports by 30%, forcing reductions in farmgate prices and eroding exporter profit margins. As in a classic case of Dutch Disease, large inflows of foreign exchange–whether from surging international copper prices, foreign aid or speculative financial inflows–have contributed to the strengthening Kwacha. The subsequent rapid appreciation of the Kwacha risks making much of Zambia’s export agriculture uncompetitive on world markets.

Accounting for this finite size effect is key to determining the infinite nuclear matter phase diagram from experimental data.

description: An income inequality has been expanded in Japan and some policy is highly needed to revitalize rural areas. This study aims to show causative factors on regional satisfaction level by the estimation of the structural equation model (SEM) with data of each town in Yamagata and Yamaguchi prefectures. Results demonstrate that (i) both the economic situations and social capital (represented by trust, altruistic moral and human network) positively affected the satisfaction level, but there is a trade-off between these effects, (ii) public facilities can increase satisfaction level as long as these facilities are built with consideration of residents' needs and quality, and (iii) the economic factor and social capital have indirect effects, affecting to satisfaction via other factors, and there are some trade-off effects within the indirect paths. Hence, regional economic gaps can be alleviated by the social capital that is highly maintained in less favored areas. The same tendency as above is shown in both prefectures, so it can be said that these factors are possibly general in Japan.

description: The energy spectra of light-mass kaonic nuclei were investigated using the theoretical framework of the $0s$-orbital model with zero-range $\bar{K} N$ and $\bar{K}\bar{K}$ interactions of effective single-channel real potentials. The energies of the $\bar{K} NN$, $\bar{K} NNN$, $\bar{K} NNNN$, $\bar{K}\bar{K} N$, and $\bar{K}\bar{K} NN$ systems were calculated in the cases of weak- and deep-binding of the $\bar{K} N$ interaction, which was adjusted to fit the $Λ(1405)$ mass with the energy of the $\bar{K} N$ bound state. The results qualitatively reproduced the energy systematics of kaonic nuclei calculated via other theoretical approaches. In the energy spectra of the $\bar{K} NN$ and $\bar{K}\bar{K} NN$ systems, the lowest states $\bar{K} NN(J^π,T=0^-,1/2)$ and $\bar{K}\bar{K} NN(0^+,0)$ were found to have binding energies approximately twice and four times as large as that of the $\bar{K} N(1/2^-,0)$ state, respectively. Higher $(J^π,T)$ states including $\bar{K} NN(1^-,1/2)$, $\bar{K}\bar{K} NN(0^+,1)$, and $\bar{K}\bar{K} NN(1^+,1)$ were predicted at energies of 9--25 MeV below the antikaon-decay threshold. The effective $Λ(1405)$-$Λ(1405)$ interaction in the $\bar{K}\bar{K} N N$ system was also investigated via a $\bar{K} N+\bar{K} N$-cluster model. Strong and weak $Λ(1405)$-$Λ(1405)$ attractions were obtained in the $S^π=0^+$ and $S^π=1^-$ channels, respectively. The $Λ(1405)$-$Λ(1405)$ interaction in the $$\bar{K}\bar{K} NN$ system was compared with the effective $d$-$d$ interaction in the $NNNN$ system, and the properties of dimer-dimer interactions in hadron and nuclear systems were discussed.

description: This study addresses the impact of trade openness on technical efficiency in the U.S. agricultural sector. The results indicate that trade protectionism illustrated with a decrease in the share of agricultural imports in agricultural GDP led to an increase in technical efficiency. A change in the share of agricultural exports in agricultural GDP had no impact on technical efficiency. These results are partially consistent with the premise of the new trade theory, but also seem to be driven by the intricacies of the agricultural sector and agricultural policy in the US and internationally.

description: The quantization of phase is still an open problem. In the approach of Susskind and Glogower so called cosine and sine operators play a fundamental role. Their eigenstates in the Fock representation are related with the Chebyshev polynomials of the second kind. Here we introduce more general cosine and sine operators whose eigenfunctions in the Fock basis are related in a similar way with arbitrary orthogonal polynomial sets on the intervall [-1,1]. To each polynomial set defined in terms of a weight function there corresponds a pair of cosine and sine operators. Depending on the symmetry of the weight function we distinguish generalized or extended operators. Their eigenstates are used to define cosine and sine representations and probability distributions. We consider also the inverse arccosine and arcsine operators and use their eigenstates to define cosine-phase and sine-phase distributions, respectively. Specific, numerical and graphical results are given for the classical orthogonal polynomials and for particular Fock and coherent states.

Material examined. 11 ♀♀, 7 ♂♂ (MNHN-IU-2018- 1768) and 1 dissected ♀ (figured) from Ciona intestinalis (Linnaeus, 1758), Adriatic Sea.
Diagnostic characters of female. Body (Fig. 16A) of dissected female 2.50 mm long. Caudal rami (Fig. 16B) widely separated from one another, about 2.9 times longer than wide (132×45 μm) and about 1.1 timeslongerthan anal somite (118×145 μm), and setulose on both outer and inner margins; outer lateral seta located at 67% of ramus length.Rostrumlongerthanwide, taperingtowardsangular apex. Antennule 15-segmented. Antenna rather stout with 2 equal exopodal setae; compound distal endopodal segment about 3 timeslongerthan wide. Mandibular endopod with 3 and 9 setae on first and second segments, respectively. Maxillule indistinctly 2-segmented with 1 and 4 setae on first and second segments, respectively. Maxilla 5-segmented; syncoxawith 4, 1, 2, and 3 setaeon first to fourth endites, respectively; basis with claw plus 2 setae; endopod 3-segmentedwith 1, 1, and 4 setaeonfirst to third segments, respectively. Maxilliped with 10, 1, and 3 setae on first to third segments, respectively. Legs 1–4 as typical for genus. Leg 5 (Fig. 16C) protopod with about 15 spinules scattered irregularly along inner margin and with elongate outer extension bearing plumose seta at tip and 1 subdistal tooth on inner margin; exopodal segment subcircular, about 1.3 times as long as wide (32×25 μm), armedwith 1 spineand 1 plumose seta; ornamented with 1 denticle distally on outer margin and 3 spinules on inner margin near base of spine.
Remarks. As Sars (1921) noted, the caudal ramus is about 3 times longer than wide and only slightly longer than the anal somite, and the outerlateral seta on the ramus is positioned subdistally. In addition, the protopod of leg 5 has an elongate digitiform outer process and distinctly spiniferous inner margin, and the exopodal segment is suboval with a strong inner spine. These characteristic features of N. elegans are present in our material from the Adriatic Sea. The species was originally reported from Swedish waters (Thorell, 1859) and its known distribution extends from Scandinavia, along the coast of northwestern Europe and into the Mediterranean (Illg, 1958; Illg & Dudley, 1961).

description: The U.S. government recruits immigrant workers through the H-2A program as a short-term solution to the agricultural sectors’ labor shortage problem. Although the sector insists hiring immigrant workers is essential for their survival, history has proven the socio-economic cost for doing so is enormous. This paper aims to investigate the contribution of labor to agricultural production efficiency. A discussion of marginal rate of technical substitution, economies of scale, and economies of scope will also be included. The stochastic production frontier regression approach was applied to input/output data collected from a survey of tree nut growers in Butte County, California. Results indicate the labor input is not significant in deciding farm production efficiency. Instead of attempting to increase short-term labor, producers’ and policy makers’ efforts should be directed toward improving the logistics of farm management and the quality of labor, thus more efficiently utilizing available resources.
Application of wavelet transform to electricity price forecasting
Creators: name: Xu, Haiteng
Publisher: name: University of British Columbia
Year: 2009

description: In order to improve the overall efficiency of electric power industry, since 1990's, deregulation of power industry has been implemented around the world by introducing competitions in generation, wholesale and retail sectors. The process of determining electricity price of electricity market is closely coupled with the process of power system operation and this results in an extremely volatile electricity price. This volatile electricity price not only brings unprecedented risk to customers but also brings more uncertainties and difficulties to power system operation, as electricity price also affects the behavior of generation, transmission and demand sections in electricity market. Therefore, modeling and forecasting electricity price is a very important topic. Aiming at developing a simple, affordable and accurate electricity price forecasting model for electricity consumers, this thesis studies the mechanism of electricity price behavior, explores the feasibility of applying wavelet transform to electricity forecasting, and tries to improve the performance of short-term (one day ahead) electricity price forecasting. The difficulty of forecasting electricity price includes price spikes and random changes. In this research, we have tried to solve this difficulty with wavelet transform and our simulation results show that wavelet transform is able to handle the spikes and random changes in electricity price and substantially improve the performance of electricity forecasting.

description: The neutron fraction in the very high energy cosmic rays near the Greisen-Zatsepin-Kuzmin (GZK) cutoff energy is analyzed by taking into account the time dilation effect of the neutron decays and also the pion photoproduction behaviors above the GZK cutoff. We predict a non-trivial neutron fraction above the GZK cutoff and a negligibly small neutron fraction below. However, there should be a large antiproton fraction in the high energy cosmic rays below the GZK cutoff in several existing models for the observed cosmic-ray events above and near the GZK cutoff. Such a large antiproton fraction can manifest itself by the muon charge ratio $μ^+/μ^-$ in the collisions of the primary nucleon cosmic rays with the atmosphere, if there is no neutron contribution. We suggest to use the muon charge ratio as one of the information to detect the composition of the primary cosmic rays near or below the GZK cutoff.

B 831 (137181) 2022] had proposed that for a spherically fractal structure the minimal increase of the horizon area is the area of the smallest bubble sphere. And the corresponding black hole entropy is of a logarithmic form, which is similar to that of Boltzmann entropy under a certain condition. Based on these, we re-derive the entropy of the Barrow's Einstein-power-Yang-Mills (EPYM) AdS black hole, and calculate the temperature and heat capacity of the Barrow's EPYM AdS black hole. There exists an interesting phenomena that the ratio between the Barrow's temperature and the Hawking temperature of the EPYM AdS black hole is fully consistent with that of other Schwarzschild-like black holes. The Barrow's temperature and Hawking temperature with the certain range of $Λ$ are monotonically increasing and the corresponding heat capacities are all positive, which means these black holes are thermodynamically stable. Besides, for the Barrow's EPYM AdS black hole its heat capacity has a Schottky anomaly-like behavior, which may reflect the existence of the discrete energy level and the microscopical degree of freedom.

Generating solutions for charged stellar models in general relativity

description: It is shown that the expressions for the tangential pressure, the anisotropy factor and the radial pressure in the Einstein - Maxwell equations may serve as generating functions for charged stellar models. The latter can incorporate an equation of state when the expression for the energy density is also used. Other generating functions are based on the condition for the existence of conformal motion (conformal flatness in particular) and the Karmarkar condition for embedding class one metrics, which do not depend on charge. In all these cases the equations are linear first order differential equations for one of the metric components and Riccati equations for the other. The latter may be always transformed into second order homogenous linear differential equations. These conclusions are illustrated by numerous particular examples from the study of charged stellar models.

Roboscope : a rebotic input : output device for enhancing computer aimators creativity and expression
Creators: name: Flores, Edgar
Publisher: name: University of British Columbia
Year: 2009

description: We describe a novel three dimensional (3D) bi-directional modular input/output device for choreographing and animating computer creatures called Roboscope. Our system consists of small, one degree of freedom robotic modules that can be assembled to create 1, 2 and 3 degree of freedom joints that are assembled into moveable and moving figures. As an input device, movement of the physical figure makes the computer figure move. As an output device, movement of the computer figure makes the physical figure move. Roboscope keeps the input and output workspace together and provides true multi-degree of freedom joints that enables animators to keep their attention focused on one task space rather than dividing it between screen and physical space. Roboscope also provides physical playback of stored movements and "undo" abilities for motion editing. These features support the animators' creative and expressive process better than current inputonly devices.

description: This research uses a sequence of hedonic housing price regressions to estimate open space amenity values. The iterative approach empirically identifies the range of distance over which open space affects housing values. After controlling for numerous other factors in the spatial hedonic model, simple functional relationships were established between the implicit prices of developed open space, forest-land open space, and agriculture-wetland open space and the buffer radius of the area surrounding a given location. In the case of Nashville-Davidson County, Tennessee, households place a positive value on additional developed open space and forest-land open space up to distances of 2.2 miles and 1.5 miles, respectively, and a negative value for additional agriculture-wetland open space up to 0.8-miles from their location. Implicit-price-buffer-size functional relationships found in this study may be useful to local planners or policymakers. For example, local policymakers can identify the set of homeowners who would receive positive amenity values from developed open space or from preservation of forest-land open space, given the distance thresholds determined. Estimates of amenity and disamenity values of homeowners would allow the aggregate value generated by a particular open-space site to be estimated. The aggregate value consumers receive reflects the value residents place on neighborhood open space and is an estimate of the value of open-space as a public good. Thus, decision makers can prioritize specific open-space establishment or preservation decisions by not only accounting for the costs of establishing or preserving open space, but also estimating the public value of open space.

description: Soft phonons and diffuse scattering in insulating La$_{2-x}$Sr$_{x}$CuO$_4$ ($x=0.05$) have been studied by the neutron scattering technique. The X-point phonon softens from high temperature towards the structural transition temperature $T_{s}=410$ K, and the Z-point phonon softens again below 200 K. The Z-point phonon softening persists to low temperature, in contrast to the behavior observed in the superconducting $x=0.15$ compound, in which the Z-point phonon hardens below $T_c$. The diffuse scattering associated with the structural phase transition at 410 K appears at commensurate positions. These results highlight interesting differences between superconducting and insulating samples.

description: Three recent reports have estimated the market impacts of domestic offset programs, including afforestation, contained in the American Clean Energy and Security Act (ACES). The magnitude of these estimated impacts motivates this study. We show that with carbon prices as low as $30 per metric ton, a significant number of U.S. crop acres would be used to grow trees and this would cause price increases for some U.S. commodities. Although we present only one carbon price scenario, the modeling approach that we use suggests that the acreage and price impacts we describe here would increase at higher carbon prices.
Discovering an Invisibly Decaying Higgs at Hadron Colliders

description: A Higgs boson lighter than 2 m_W that decays mostly into invisible channels (e.g., dark matter particles) is theoretically well-motivated. We study the prospects for discovery of such an invisible Higgs, h_inv, at the LHC and the Tevatron in three production modes: (1) in association with a Z, (2) through Weak Boson Fusion (WBF), and (3) accompanied by a jet. In the Z+h_inv channel, we show that the LHC can yield a discovery signal above 5 sigma with 10 fb-1 of integrated luminosity for a Higgs mass of 120 GeV. With 30 fb-1 the discovery reach extends up to a Higgs mass of 160 GeV. We also study the extraction of the h_inv mass from production cross sections at the LHC, and find that combining WBF and Z+h_inv allows a relatively model-independent determination of the h_inv mass with an uncertainty of 35-50 GeV (15-20 GeV) with 10 (100) fb-1. At the Tevatron, a 3 sigma observation of a 120 GeV h_inv in any single channel is not possible with less than 12 fb-1 per detector. However, we show that combining the signal from WBF with the previously-studied Z+h_inv channel allows a 3 sigma observation of h_inv with 7 fb-1 per detector. Because of overwhelming irreducible backgrounds, h_inv+j is not a useful search channel at either the Tevatron or the LHC, despite the larger production rate.

description: It is commonly assumed that the energy density of the Universe was dominated by radiation between reheating after inflation and the onset of matter domination 54,000 years later. While the abundance of light elements indicates that the Universe was radiation dominated during Big Bang Nucleosynthesis (BBN), there is scant evidence that the Universe was radiation dominated prior to BBN. It is therefore possible that the cosmological history was more complicated, with deviations from the standard radiation domination during the earliest epochs. Indeed, several interesting proposals regarding various topics such as the generation of dark matter, matter-antimatter asymmetry, gravitational waves, primordial black holes, or microhalos during a nonstandard expansion phase have been recently made. In this paper, we review various possible causes and consequences of deviations from radiation domination in the early Universe - taking place either before or after BBN - and the constraints on them, as they have been discussed in the literature during the recent years.
