Efficient computation of null affine parameters

description: Finding affine parameters for null geodesics is often of considerable physical importance, especially when studying the paths swept out by null geodesics or when dealing with conservation laws and/or averaged energy conditions. But explicitly finding null affine parameters is also often quite tedious and can sometimes even be somewhat tricky. Herein we shall demonstrate that the existence of a conformally related spacetime containing a conformal Killing vector, timelike in the domain of outer communication, is quite sufficient to define a preferred set of spatial three-slices -- on which a well-defined "affine" three-metric can be introduced to capture the notion of affine null parameter -- before explicitly finding the null geodesics. The construction depends on the properties of conformal transformations and on the conserved quantity associated with the conformal Killing vector. Having the affine null parameter in hand before attempting to find the actual null geodesics often quite radically simplifies other parts of the analysis. We emphasize that the successful identification of affine null parameters is a general-purpose tool of wide applicability in both general relativistic and astrophysical settings.

description: Trans-Neptunian Objects (TNOs) provide a window into the history of the Solar System, but they can be challenging to observe due to their distance from the Sun and relatively low brightness. Here we report the detection of 75 moving objects that we could not link to any other known objects, the faintest of which has a VR magnitude of $25.02 \pm 0.93$ using the KBMOD platform. We recover an additional 24 sources with previously-known orbits. We place constraints on the barycentric distance, inclination, and longitude of ascending node of these objects. The unidentified objects have a median barycentric distance of 41.28 au, placing them in the outer Solar System. The observed inclination and magnitude distribution of all detected objects is consistent with previously published KBO distributions. We describe extensions to KBMOD, including a robust percentile-based lightcurve filter, an in-line graphics processing unit (GPU) filter, new coadded stamp generation, and a convolutional neural network (CNN) stamp filter, which allow KBMOD to take advantage of difference images. These enchancements mark a significant improvement in the readiness of KBMOD for deployment on future big data surveys such as LSST.

description: Let $\mathbb{F}$ be a finite field of odd order and $a,b\in\mathbb{F}\setminus\{0,1\}$ be such that $χ(a) = χ(b)$ and $χ(1-a)=χ(1-b)$, where $χ$ is the extended quadratic character. Let $Q_{a,b}$ be the quasigroup upon $\mathbb{F}$ defined by $(x,y)\mapsto x+a(y-x)$ if $χ(y-x) \ge 0$, and $(x,y)\mapsto x+b(y-x)$ if $χ(y-x) = -1$. We show that $Q_{a,b} \cong Q_{c,d}$ if and only if $\{a,b\}= \{α(c),α(d)\}$ for some $α\in \textrm{aut}(\mathbb{F})$. We also characterise $\textrm{aut}(Q_{a,b})$ and exhibit further properties, including establishing when $Q_{a,b}$ is a Steiner quasigroup or is commutative, entropic, left or right distributive, flexible or semisymmetric. In proving our results we also characterise the minimal subquasigroups of $Q_{a,b}$.

description: We describe a unified and coherent syntactic framework for supporting a semantically-informed syntactic approach to statistical machine translation. Semantically enriched syntactic tags assigned to the target-language training texts improved translation quality. The resulting system significantly outperformed a linguistically naive baseline model (Hiero), and reached the highest scores yet reported on the NIST 2009 Urdu-English translation task. This finding supports the hypothesis (posed by many researchers in the MT community, e.g., in DARPA GALE) that both syntactic and semantic information are critical for improving translation quality—and further demonstrates that large gains can be achieved for low-resource languages with different word order than English.

description: Baryons in the large N limit of two-dimensional Gross-Neveu models are reconsidered. The time-dependent Dirac-Hartree-Fock approach is used to boost a baryon to any inertial frame and shown to yield the covariant energy-momentum relation. Momentum distributions are computed exactly in arbitrary frames and used to interpolate between the rest frame and the infinite momentum frame, where they are related to structure functions. Effects from the Dirac sea depend sensitively on the occupation fraction of the valence level and the bare fermion mass and do not vanish at infinite momentum. In the case of the kink baryon, they even lead to divergent quark and antiquark structure functions at x=0.

description: Purpose: Alternative service delivery approaches are required to provide support for children with communication difficulties in underserved communities. Schools have a unique set of assets that can be utilized to provide this support. This study explored what the education sector and classrooms in the early years of schooling offer as support for children with communication difficulties in an underserved Majority World country, the Maldives. The objective was to identify opportunities to enhance support provided for these children.Method: A qualitative multimethod approach was used involving (a) 520 min of classroom observational data from four remote schools, (b) interviews with four special education needs teachers, and (c) an interview with a Ministry of Education official. Classroom observational data were analyzed using the Communication Supporting Classroom Observation Tool. Deductive content analysis was used to analyze the interview data.Results: The support system aimed to reflect the Inclusive Education Policy of the Maldives. The Ministry of Education official and teachers raised concerns regarding lack of allied health services such as speech-language therapy in schools. Teachers frequently used certain communication supporting interactions such as imitation in classrooms. Missed opportunities to enhance communication were observed, including limited use of some interaction features such as modeling language, limited planned opportunities for children to interact in class, and limited resources in the environment to develop communication in Grade 1 and 2 compared to preschool.Conclusion: Findings suggest building capacity among teachers and training teachers on identified classroom communication support areas to enhance support for children with communication difficulties.

description: Exact wormhole solutions, while eagerly sought after, often have the appearance of being overly specialized or highly artificial. A case for the possible existence of traversable wormholes would be more compelling if an abundance of solutions could be found. It is shown in this note that for many of the wormhole geometries in the literature, the exact solutions obtained imply the existence of large sets of additional solutions.

description: A \emph{Latin square} is a matrix of symbols such that each symbol occurs exactly once in each row and column. A Latin square $L$ is \emph{row-Hamiltonian} if the permutation induced by each pair of distinct rows of $L$ is a full cycle permutation. Row-Hamiltonian Latin squares are equivalent to perfect $1$-factorisations of complete bipartite graphs. For the first time, we exhibit a family of Latin squares that are row-Hamiltonian and also achieve precisely one of the related properties of being column-Hamiltonian or symbol-Hamiltonian. This family allows us to construct non-trivial, anti-associative, isotopically $L$-closed loop varieties, solving an open problem posed by Falconer in 1970.

description: The manganocuprate compound Gd3Ba2Mn2Cu2O12 (Gd-3222) has been synthesized by conventional solid state reaction method and its magnetic behavior has been studied by dc and ac magnetization (M) and heat capacity (C) measurements as a function of temperature (T). This compound crystallizes in a tetragonal structure (space group I4/mmm). We find that this compound exhibits three magnetic transitions, around 2.5, 4.8 and 9 K, as inferred from dc and ac magnetic susceptibility (chi) data. However, no evidence for a well-defined lambda-anomaly is found in C(T) above 1.8 K, though there is a gradual upturn below about 10 K. An application of a magnetic field results in a peak around 5K, while ac chi appears to show a very weak frequency dependence below 9 K. Isothermal M curve at 1.8 K exhibits a weak hysteresis without any evidence for saturation even at fields as high as 120 kOe. These results imply that this compound undergoes a spin-glass-like freezing at low temperatures, though the exact nature of the magnetic transition at 10 K is not clear. The magnitude of the magnetocaloric effect, as inferred from M and C data, is quite large over a wide temperature range below 50 K peaking around 4 K.

Unidirectional decomposition method for obtaining exact localized waves solutions totally free of backward components

description: In this paper we use a unidirectional decomposition capable of furnishing localized wave pulses, with luminal and superluminal peak velocities, in exact form and totally free of backward components, which have been a chronic problem for such wave solutions. This decomposition is powerful enough for yielding not only ideal nondiffracting pulses but also their finite energy versions still in exact analytical closed form. Another advantage of the present approach is that, since the backward spectral components are absent, the frequency spectra of the pulses do not need to possess ultra-widebands, as it is required by the usual localized waves (LWs) solutions obtained by other methods. Finally, the present results bring the LW theory nearer to the real experimental possibilities of usual laboratories.

description: The generalized Morita-Miller-Mumford classes of a smooth oriented manifold bundle are defined as the image of the characteristic classes of the vertical tangent bundle under the Gysin homomorphism. We show that if the dimension of the manifold is even, then all MMM-classes in rational cohomology are nonzero for some bundle. In odd dimensions, this is also true with one exception: the MMM-class associated with the Hirzebruch $\cL$-class is always zero. We also show a similar result for holomorphic fibre bundles.

Criteria for generalized macroscopic and mesoscopic quantum coherence

Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: We consider macroscopic, mesoscopic and "S-scopic" quantum superpositions of eigenstates of an observable, and develop some signatures for their existence. We define the extent, or size $S$ of a superposition, with respect to an observable \hat{x}, as being the range of outcomes of \hat{x} predicted by that superposition. Such superpositions are referred to as generalized $S$-scopic superpositions to distinguish them from the extreme superpositions that superpose only the two states that have a difference $S$ in their prediction for the observable. We also consider generalized $S$-scopic superpositions of coherent states. We explore the constraints that are placed on the statistics if we suppose a system to be described by mixtures of superpositions that are restricted in size. In this way we arrive at experimental criteria that are sufficient to deduce the existence of a generalized $S$-scopic superposition. The signatures developed are useful where one is able to demonstrate a degree of squeezing. We also discuss how the signatures enable a new type of Einstein-Podolsky-Rosen gedanken experiment.

Foreign investment decisions of western Canadian firms
Creators: name: Wahab, Abdul
Publisher: name: University of British Columbia
Year: 2010

description: An earlier study of the foreign investment decision process of U.S. firms by Aharoni had suggested the dominance of behavioural characteristics over criteria based on economic theories in determining such decisions. His research did not however, provide strong analytical proofs and part of the intellectual derivation for this study was the search for such proof. This was combined with the effort to bring into the field of knowledge some information about an under-reported sub-sample of foreign investors, namely firms from Western Canada. The main structure of the research model consisted of six identified stages in the foreign investment decision process. In turn, six sets of variables were developed which corresponded to each of these stages: awareness through initiating forces, investigation, commitments, negotiations, uncertainty, and the final decision. To test the research model five hypotheses were developed. The first hypothesis corresponding to stage one contended that endogenous initiating forces are more important in creating awareness of foreign direct investment opportunities than exogenous initiating forces. The second hypothesis relating to stage two claimed that those who conduct a sequential investigation will judge the subjectively estimated cost of that investigation to be significantly higher than those who do not conduct a sequential investigation. The third hypothesis concerning stage three stated that the extent of investigation and the degree of commitments are positively related. The fourth hypothesis relating to negotiations in stage four and uncertainty in stage five said that there exists a positive relationship between the extent of negotiations and the amount of uncertainty. The fifth hypothesis corresponding to stage six claimed that in those cases where the decision has been made to invest abroad, there will be strong initiating forces, more investigation, greater degree of commitments, greater extent of negotiations, and smaller amount of uncertainty than in those cases where the decision has been made not to invest abroad. The hypotheses were tested against data collected on 89 decisions. The data supported all the hypotheses excepting the first part of the last hypothesis which said that the initiating forces will be stronger in the case of positive decisions. This was explained in terms of the presence of intervening variables such as investigation, commitments, negotiations, and uncertainty. The research has implications for home and host country and the theory of the firm. Profit is shown as an important consideration in the investment decisions. Resource-based firms are led by the location of resources and they have a desire to internalize the source of supply and demand. Some of the areas for further research are: a comparison of foreign and domestic investment decisions and a study of buying and financing practices of Canadian firms that invest abroad.

description: The nonlinear process of second harmonic generation (SHG) in monolayer (1L) transition metal dichalcogenides (TMD), like $WS_2$, strongly depends on the polarization state of the excitation light. Combining plasmonic nanostructures with $1L-WS_2$ by transferring it onto a plasmonic nanoantenna array, a hybrid metasurface is realized impacting the polarization dependency of its SHG. Here, we investigate how plasmonic dipole resonances affect the process of SHG in plasmonic-TMD hybrid metasurfaces by nonlinear spectroscopy. We show, that the polarization dependency is affected by the lattice structure of plasmonic nanoantenna arrays as well as by the relative orientation between the $1L-WS_2$ and the individual plasmonic nanoantennas. In addition, such hybrid metasurfaces show SHG in polarization states, where SHG is usually forbidden for either $1L-WS_2$ or plasmonic nanoantennas. By comparing the SHG in these channels with the SHG generated by the hybrid metasurface components, we detect an enhancement of the SHG signal by a factor of more than 40. Meanwhile, an attenuation of the SHG signal in usually allowed polarization states is observed. Our study provides valuable insight into hybrid systems where symmetries strongly affecting the SHG and open up the possibility for tailoring the SHG in $1L-WS_2$ for future applications.
A review of empirical evidence on copyright exceptions
Creators: name: Meletti, Bartolomeo
Publisher: name: Zenodo
Year: 2021

description: Exceptions are an essential part of the copyright system. They aim to encourage innovation, serve the public interest or respond to market failures. While extensive theoretical and doctrinal research has examined the history, nature, justification, and judicial interpretation of exceptions, empirical evidence in this area of copyright law is limited. This article aims to synthesise the empirical studies on exceptions currently catalogued on the Copyright Evidence Portal. After a short introduction to the topic, the article reviews the debates and questions addressed by scholars investigating exceptions empirically. In doing so, it identifies five main areas of study: i) judicial interpretation; ii) evaluating policy options; iii) impact of exceptions; iv) public domain and incentives; and v) technology and compensation. Under each area of study, the article summarises the main findings of the catalogued studies with a view to generating a picture of existing evidence and research agendas. Finally, the article highlights recent legislative and policy developments that may suggest potential directions for future research.

Bulk-boundary correspondence and singularity-filling in long-range free-fermion chains

description: The bulk-boundary correspondence relates topologically-protected edge modes to bulk topological invariants, and is well-understood for short-range free-fermion chains. Although case studies have considered long-range Hamiltonians whose couplings decay with a power-law exponent $α$, there has been no systematic study for a free-fermion symmetry class. We introduce a technique for solving gapped, translationally invariant models in the 1D BDI and AIII symmetry classes with $α>1$, linking together the quantized winding invariant, bulk topological string-order parameters and a complete solution of the edge modes. The physics of these chains is elucidated by studying a complex function determined by the couplings of the Hamiltonian: in contrast to the short-range case where edge modes are associated to roots of this function, we find that they are now associated to singularities. A remarkable consequence is that the finite-size splitting of the edge modes depends on the topological winding number, which can be used as a probe of the latter. We furthermore generalise these results by (i) identifying a family of BDI chains with $α<1$ where our results still hold, and (ii) showing that gapless symmetry-protected topological chains can have topological invariants and edge modes when $α-1$ exceeds the dynamical critical exponent.

description: The calculation of the electron g-factor was carried out in 1950 by Karplus and Kroll. Seven years later, Petermann detected and corrected a serious error in the calculation of a Feynman diagram. Although it is hard to believe, neither the original calculation nor the subsequent correction was ever published. Therefore, the entire prestige of QED and the Standard Model depends on the calculation of a single Feynman diagram (IIc) that has never been published and cannot be independently verified. In this article we begin the search for any published recalculation of this Feynman diagram IIc that allows us to independently validate the theoretical calculation.

description: We consider a ring of three quantum dots mutually coupled by antiferromagnetic exchange interactions, and tunnel-coupled to two metallic leads: the simplest device in which the consequences of local frustration arising from internal degrees of freedom may be studied within a 2-channel environment. Two-channel Kondo (2CK) physics is found to predominate at low-energies in the mirror-symmetric systems considered, with a residual spin 1/2 overscreened by coupling to both leads. It is however shown that two distinct 2CK phases, with different ground state parities, arise on tuning the interdot exchange couplings. In consequence a frustration-induced quantum phase transition occurs, the 2CK phases being separated by a quantum critical point for which an effective low-energy model is derived. Precisely at the transition, parity mixing of the quasi-degenerate local trimer states acts to destabilise the 2CK fixed points; and the critical fixed point is shown to consist of a free pseudospin together with effective 1-channel spin quenching, itself reflecting underlying channel-anisotropy in the inherently 2-channel system. Numerical renormalization group techniques and physical arguments are used to obtain a detailed understanding of the problem, including study of both thermodynamic and dynamical properties of the system.

ABSTRACTUrban stormwater problems are indisputable, many countries have suffered from such problems and will be exposed to greater threats due to urban sprawl and climate change. For controlling urban stormwater, conventional stormwater approaches rely on underground pipeline systems to drain stormwater away as soon as possible. With people paying more attention to urban stormwater issues and environmental quality, multiple strategies which could be collectively called Sustainable Stormwater Management (SSM), have been proposed and implemented for solving different local stormwater problems, enhancing the natural water cycle and protecting receiving waters and aquatic habitats. This paper reviews the literature and describes how ecologically-based urban design (EBUD) interfaces and improves SSM during urban development. SSM covers planning and engineering aspects and EBUD plays an important role for keeping and mimicking nature and also sketching out the best plan for arranging SSM measures. EBUD provides stakeholders with a philosophy and guidelines from an urban design perspective for SSM development, spanning from stormwater mitigation and control to protection of the natural water ecosystem of the receiving water bodies. Subsequent research will use a case study approach to identify priority issues to address when formulating guidelines for EBUD in SSM.

description: We look for $ΔΔ$ and $NΔ$ resonances by calculating $NN$ scattering phase shifts of two interacting baryon clusters of quarks with explicit coupling to these dibaryon channels. Two phenomenological nonrelativistic chiral quark models giving similar low-energy $NN$ properties are found to give significantly different dibaryon resonance structures. In the chiral quark model (ChQM), the dibaryon system does not resonate in the $NN$ $S$-waves, in agreement with the experimental SP07 $NN$ partial-wave scattering amplitudes. In the quark delocalization and color screening model (QDCSM), the $S$-wave NN resonances disappear when the nucleon size $b$ falls below 0.53 fm. Both quark models give an $IJ^P = 03^+$ $ΔΔ$ resonance. At $b=0.52 $fm, the value favored by baryon spectrum, the resonance mass is 2390 (2420) MeV for the ChQM with quadratic (linear) confinement, and 2360 MeV for the QDCSM. Accessible from the $^3D_3^{NN}$ channel, this resonance is a promising candidate for the known isoscalar ABC structure seen more clearly in the $pn$$\to $$dππ$ production cross section at 2410 MeV in the recent preliminary data reported by the CELSIUS-WASA Collaboration. In the isovector dibaryon sector, our quark models give a bound or almost bound $^5S_2^{ΔΔ}$ state that can give rise to a $^1D_2^{NN}$ resonance. None of the quark models used has bound $NΔ$ $P$-states that might generate odd-parity resonances.

description: Motives or goals are recognized in psychology literature as the most fundamental drive that explains and predicts why people do what they do, including when they browse the web. Although providing enormous value, these higher-ordered goals are often unobserved, and little is known about how to leverage such goals to assist people's browsing activities. This paper proposes to take a new approach to address this problem, which is fulfilled through a novel neural framework, Goal-directed Web Browsing (GoWeB). We adopt a psychologically-sound taxonomy of higher-ordered goals and learn to build their representations in a structure-preserving manner. Then we incorporate the resulting representations for enhancing the experiences of common activities people perform on the web. Experiments on large-scale data from Microsoft Edge web browser show that GoWeB significantly outperforms competitive baselines for in-session web page recommendation, re-visitation classification, and goal-based web page grouping. A follow-up analysis further characterizes how the variety of human motives can affect the difference observed in human behavioral patterns.

description: We present two series of MOST (Microvariability & Oscillations of STars) space-based photometry, covering nearly continuously 10 days in 2004 and 30 days in 2007, of selected variable stars in the upper Main Sequence of the old open cluster M67. New high-precision light curves were obtained for the blue-straggler binary/triple systems AH Cnc, ES Cnc and EV Cnc. The precision and phase coverage of ES Cnc and EV Cnc is by far superior to any previous observations. The light curve of ES Cnc is modelled in detail, assuming two dark photospheric spots and Roche geometry. An analysis of the light curve of AH Cnc indicates a low mass ratio (q about 0.13) and a high inclination angle for this system. Two new long-period eclipsing binaries, GSC 814-323 and HD75638 (non-members of M67) were discovered. We also present ground-based DDO spectroscopy of ES Cnc and of the newly found eclipsing binaries. Especially interesting is HD75638, a member of a visual binary, which must itself be a triple or a higher-multiplicity system. New light curves of two delta Scuti pulsators, EX Cnc and EW Cnc, have been analyzed leading to detection of 26 and 8 pulsation frequencies of high temporal stability.

description: This article presents a study of the grand canonical Bose-Einstein (BE) statistics for a finite number of particles in an arbitrary quantum system. The thermodynamical quantities that identify BE condensation -- namely, the fraction of particles in the ground state and the specific heat -- are calculated here exactly in terms of temperature and fugacity. These calculations are complemented by a numerical calculation of fugacity in terms of the number of particles, without taking the thermodynamic limit. The main advantage of this approach is that it does not rely on approximations made in the vicinity of the usually defined critical temperature, rather it makes calculations with arbitrary precision possible, irrespective of temperature. Graphs for the calculated thermodynamical quantities are presented in comparison to the results previously obtained in the thermodynamic limit. In particular, it is observed that for the gas trapped in a 3-dimensional box the derivative of specific heat reaches smaller values than what was expected in the thermodynamic limit -- here, this result is also verified with analytical calculations. This is an important result for understanding the role of the thermodynamic limit in phase transitions and makes possible to further study BE statistics without relying neither on the thermodynamic limit nor on approximations near critical temperature.

description: We consider a spin impurity with multiple energy levels moving in a non-interacting Fermi sea, and theoretically solve this Fermi spin polaron problem at nonzero temperature by using a non-self-consistent many-body $T$-matrix theory. We focus on the simplest case with spin half, where the two energy states of the impurity are coupled by a Rabi flip term. At small Rabi coupling, the impurity exhibits damped Rabi oscillations, where the decoherence is caused by the interaction with the Fermi sea, as recently reported in Fermi polaron experiments with ultracold atoms. We investigate the dependence of Rabi oscillations on the Rabi coupling strength and examine the additional nonlinear damping due to large Rabi coupling. At finite temperature and at nonzero impurity concentration, the impurity can acquire a pronounced momentum distribution. We show that the momentum/thermal average can sizably reduce the visibility of Rabi oscillations. We compare our theoretical predictions to the recent experimental data and find a good agreement without any adjustable parameter.
