description: Monolayers of transition metal dichalcogenides present an intriguing platform to investigate the interplay of excitonic complexes in two dimensional semiconductors. Here, we use optical spectroscopy to study light-matter coupling and non-equilibrium relaxation dynamics of three-particle exciton states, commonly known as trions. We identify the consequences of the exchange interaction for the trion finestructure in tungsten-based monolayer materials from variational calculations and experimentally determine the resulting characteristic differences in their oscillator strength. It allows us to quantitatively extract trion populations from time-resolved photoluminescence measurements and monitor their dynamics after off-resonant optical injection. At liquid helium temperature we observe pronounced non-equilibrium distribution of the trions during their lifetime with comparatively slow equilibration that occurs on time-scales up to several 100's of ps. In addition, we find an intriguing regime of population inversion at lowest excitation densities that builds up and is maintained during 10's of picoseconds. With increased lattice temperature the equilibrium is established more rapidly and the inversion disappears, highlighting the role of thermal activation for efficient scattering between exchange-split trions.

description: Let X be a Kobayashi hyperbolic complex manifold, and assume that X does not contain compact complex submanifolds of positive dimension (e.g., X Stein). We shall prove the following generalization of Ritt's theorem: every holomorphic self-map f of X such that f(X) is relatively compact in X has a unique fixed point p(f) in X, which is attracting. Furthermore, we shall prove that p(f) depends holomorphically on f in a suitable sense, generalizing results by Heins, Joseph-Kwack and the second author.

description: The convergent beam electron diffraction (CBED) patterns of twisted bilayer samples exhibit interference patterns in their CBED spots. Such interference patterns can be treated as off-axis holograms and the phase of the scattered waves, meaning the interlayer distance can be reconstructed. A detailed protocol of the reconstruction procedure is provided in this study. In addition, we derive an exact formula for reconstructing the interlayer distance from the recovered phase distribution, which takes into account the different chemical compositions of the individual monolayers. It is shown that one interference fringe in a CBED spot is sufficient to reconstruct the distance between the layers, which can be practical for imaging samples with a relatively small twist angle or when probing small sample regions. The quality of the reconstructed interlayer distance is studied as a function of the twist angle. At smaller twist angles, the reconstructed interlayer distance distribution is more precise and artefact free. At larger twist angles, artefacts due to the moiré structure appear in the reconstruction. A method for the reconstruction of the average interlayer distance is presented. As for resolution, the interlayer distance can be reconstructed by the holographic approach at an accuracy of 0.5 A, which is a few hundred times better than the intrinsic z-resolution of diffraction limited resolution, as expressed through the spread of the measured k-values. Moreover, we show that holographic CBED imaging can detect variations as small as 0.1 A in the interlayer distance, though the quantitative reconstruction of such variations suffers from large errors.

description: Protoplanets accrete material from their natal protostellar disks until they are sufficiently massive to open a gap in the face of the disk's viscosity that arises from the magneto-rotational instability (MRI). By computing the ionization structure within observationally well-constrained disk models, we demonstrate that poorly ionized, low viscosity "dead zones" stretch out to 12 AU within typical disks. We find that planets of terrestrial mass robustly form within the dead zones while massive Jovian planets form beyond. Dead zones will also halt the rapid migration of planets into their central stars. Finally, we argue that the gravitational scattering of low mass planets formed in the dead zone, to larger radii by a rapidly accreting Jupiter beyond, can explain the distribution of planetary masses in our solar system.

description: Since intermittent and highly variable power supply is undesirable, quantifying power yield fluctuations of wave energy converters (WECs) aids with assessment of potential deployment sites. This paper presents analysis of 3-hourly, monthly, seasonal, and inter-annual variability of power output of the M4 WEC. We compare expected performance from deployment at two wave energy hotspots: off Albany on the south-western coast of Australia and off the European Marine Energy Centre (EMEC) at Orkney, UK. We use multi-decadal wave hindcast data to predict the power that would have been generated by M4 WEC machines. The M4 machine, as a floating articulated device which extracts energy from flexing motion about a hinge, is sized according to a characteristic wavelength of the local wave climate. Using probability distributions, production duration curves, and coefficients of variation we demonstrate larger variability of the 3-hourly power yield at Orkney compared to Albany. At longer timescales, seasonal trends are highlighted through average monthly power values. From a continuity of supply perspective, we investigate occurrences of low production at three different threshold levels and calculate duration and likelihood of such events. Orkney is found to suffer from more persistent lows, causing a more intermittent power output. We also consider the effect of machine size on its power performance. Smaller machines are found to more effectively smooth out the stochastic nature of the underlying wave resource.

description: We use experimental and survey data from two natural-hazard prone countries in Latin America to test the hypothesis that natural hazards affect risk aversion. We use two methods to measure risk aversion: simple questions on the willingness to pay for a hypothetical lottery and more complicated experiments involving real pay-offs. We find that whereas the experiments provide reasonable estimates of risk aversion, the hypothetical questions result in unrealistic distributions of preferences. The experimental results strongly support the hypothesis that experiencing natural shocks makes people more risk averse, not only in the short run but also in the medium and long run.

The classic magic number N=50 is reproduced and the new number N=70 is predicted to be a robust shell closure by analysing several calculated quantities such as: two-neutron separation energies, two-neutron shell gap, neutron pairing energy, potential energy surface and neutron single particle energies with and without the tensor force. The obtained results are corroborated by shell model calculations and compared with the predictions of finite range droplet model (FRDM) and with the available experimental data. A reasonable and satisfactory agreement between the theoretical models and experiment is established.

With the same data format with MNIST, MNIST-MIX can be seamlessly applied in existing studies for handwritten digit recognition. By introducing digits from 10 different languages, MNIST-MIX becomes a more challenging dataset and its imbalanced classification requires a better design of models. We also present the results of applying a LeNet model which is pre-trained on MNIST as the baseline.

description: We study cosmology in the five-dimensional Randall-Sundrum brane-world with a stabilizing effective potential for the radion and matter localized on the branes. The analysis is performed by employing a perturbative expansion in the ratio rho/V between the matter energy density on the branes and the brane tensions around the static Randall-Sundrum solution (which has rho=0 and brane tensions +-V). This approach ensures that the matter evolves adiabatically and allows us to find approximate solutions to second order in ρ/V. Some particular cases are then analyzed in details.

description: Requiring neither active components nor complex designs, we propose and experimentally demonstrate a generic framework for undistorted asymmetric elastic-wave transmission in a thin plate just using a layer of lossless metasurface. The asymmetric transmission stems from the uneven diffraction of +1 and -1 orders on opposite sides of the metasurface, respectively. Compared with previous loss-induced strategies, the present metasurface maintains a nearly total transmission for the transportation side, but a total reflection from the opposite side, exhibiting a higher contrast ratio of transmission. Moreover, we illustrate that this strong asymmetric behavior is robust to the frequency, the incident angle and the loss effect. The present work paves new avenues to compact rectification, high resolution ultrasonography, vibration and noise control in elastodynamics and acoustics.

The position of the peak of the detected cusp is indistinguishable from the center of M54. The photometric properties of the cusp are fully compatible with those observed in the nuclei of dwarf elliptical galaxies, indicating that the Sgr dSph would appear as a nucleated galaxy independently of the presence of M54 at its center.

description: Motivated by the magnetic phase transition of a proximate Kitaev system $α$-RuCl$_3$ in the presence of a magnetic field, we study the simplest but essential quantum spin model with the ferromagnetic nearest neighboring (NN) Kitaev interaction and additional antiferromagnetic third NN Heisenberg interaction. Employing both exact diagonalization and density matrix renormalization group methods, we demonstrate that the model shows the magnetic phase transition from the zigzag order phase to the spin polarized phase through an intermediate phase in both cases when an in-plane magnetic field is applied perpendicular to the NN bond direction and when an out-of-plane field is applied, in good agreement with experimental observations. Furthermore, we verify that additional symmetric off-diagonal $Γ$ interaction and ferromagnetic Heisenberg interaction between NN spins can both suppress the intermediate phase with the in-plane field. Our result gives important clues on determining relevant interactions in the field-induced magnetic phase transition of proximate Kiteav systems.

Pre-incubation behaviour of Harlequin ducks (Histrionicus histrionicus) in Labrador : testing the function of male vigilance and aggression
Creators: name: Squires, Kelly A.
Publisher: name: University of British Columbia
Year: 2009

description: Male behaviours such as vigilance and aggression are usually assumed to function in paternity assurance during the pre-incubation period. However, the functions of these behaviours may be to protect females from conspecifics and predators during feeding and resting thereby enhancing their ability to form clutches. I studied pre-incubation behaviour in a population of Harlequin Ducks to determine how male vigilance and aggression are related to female foraging, resting and date of clutch initiation. In 2000 and 2001, 217 hours of time-activity data on 12 paired females and 16 paired males were collected on two rivers in central Labrador during the pre-incubation period. Males face greater risk of losing paternity due to mate loss than to extra-pair copulation (EPC) because EPC attempts were rare and did not result in cloacal contact due to female resistance. Most aggression was low-level 'head-nodding' by both members of a pair. Though high-level male aggression was directed at other males, it occurred during feeding and not resting, despite close proximity between resting pairs and unpaired males. High-level aggression by males was likely used to defend feeding areas and not to 'mate guard'. Harlequin Ducks were observed in lake outlets throughout the preincubation period except during spring snow melt when they were observed feeding close to flooded lakeshores. The proportion of time that males were vigilant during feeding bouts was greater when pairs were observed at the lakeshore than in the river outlets (22% versus 5%). Males were more vigilant than females and were vigilant when other males were not within sight. The frequency of male vigilance was unrelated to the female fertile period suggesting no paternity assurance function. Male vigilance and female feeding and resting were not positively correlated and vigilance and aggression were unrelated to date of clutch initiation. Males may use vigilance to detect predators to enhance female survival in 'risky' habitat

description: This small-scale study seeks to gain understanding of the experiences and learning opportunities presented by students’ participation in a volunteering project at a post-1992 city university. The participating students were all drawn from an undergraduate programme in the field of special educational needs (SEN). This research focuses on the development of students’ professional confidence, personal skills and subject-related understanding in the context of considering the values and benefits of student volunteering. Pre-volunteering (n = 32), mid-point (n = 23) and post-volunteering (n = 26) questionnaires were completed by participating students. In-depth interviews were also conducted following the 12-week volunteering period (n = 6). Statistical analysis of questionnaires was carried out using SPSS analytics software, facilitating the production of tables and charts, while open-ended responses and in-depth interviews were analysed by hand and coded using themes. The findings of the study support the linking of volunteering activity to higher education (HE) programme outcomes to facilitate accreditation and recognition for students.

The study estimates the impact of the growth in per capita income on the trade of agrifood products using data for 52 countries and 20 agrifood products for the years 1990 to 2006. The results suggest that China, Russia and Brazil have more income elastic import demand than other middle-income countries. Conversely, the income elasticities of import demand in India are similar to other low-income countries and for the most part statistically equal to zero.

description: The properties of a dilute electron gas, coupled to the lattice degrees of freedom, are studied and compared with the properties of an electron gas at half-filling, where spinless fermions with two orbitals per lattice site are considered. The simplest model which includes both the local electron-lattice interaction of the Jahn-Teller type and the electronic correlations is the $E\otimesβ$-Jahn-Teller-Hubbard model. We analyze the formation and stability of Jahn-Teller polarons and bipolarons, respectively. Our approach is based on a hopping expansion in the strong-coupling regime. The results are compared with recently published findings for the Hubbard-Holstein model [1,2]. The special case of the Jahn-Teller-Hubbard model at half-filling is mapped on a spin-1/2 Heisenberg model with phonon-dependent coupling constants. This has been derived within a projection formalism that provides a continued-fraction representation of the Green's function. We study the exact solution for two and three particles and compare it with the effective theory on the infinite lattice with one particle per site.

Sublinear-Time Algorithms for Computing & Embedding Gap Edit Distance

Year: 2020
Subjects: subject: Data Structures and Algorithms (cs.DS)

description: In this paper, we design new sublinear-time algorithms for solving the gap edit distance problem and for embedding edit distance to Hamming distance. For the gap edit distance problem, we give an $\tilde{O}(\frac{n}{k}+k^2)$-time greedy algorithm that distinguishes between length-$n$ input strings with edit distance at most $k$ and those with edit distance exceeding $(3k+5)k$. This is an improvement and a simplification upon the result of Goldenberg, Krauthgamer, and Saha [FOCS 2019], where the $k$ vs $Θ(k^2)$ gap edit distance problem is solved in $\tilde{O}(\frac{n}{k}+k^3)$ time. We further generalize our result to solve the $k$ vs $k'$ gap edit distance problem in time $\tilde{O}(\frac{nk}{k'}+k^2+ \frac{k^2}{k'}\sqrt{nk})$, strictly improving upon the previously known bound $\tilde{O}(\frac{nk}{k'}+k^3)$. Finally, we show that if the input strings do not have long highly periodic substrings, then already the $k$ vs $(1+ε)k$ gap edit distance problem can be solved in sublinear time. Specifically, if the strings contain no substring of length $\ell$ with period at most $2k$, then the running time we achieve is $\tilde{O}(\frac{n}{ε^2 k}+k^2\ell)$. We further give the first sublinear-time probabilistic embedding of edit distance to Hamming distance. For any parameter $p$, our $\tilde{O}(\frac{n}{p})$-time procedure yields an embedding with distortion $O(kp)$, where $k$ is the edit distance of the original strings. Specifically, the Hamming distance of the resultant strings is between $\frac{k-p+1}{p+1}$ and $O(k^2)$ with good probability. This generalizes the linear-time embedding of Chakraborty, Goldenberg, and Koucký [STOC 2016], where the resultant Hamming distance is between $\frac k2$ and $O(k^2)$. Our algorithm is based on a random walk over samples, which we believe will find other applications in sublinear-time algorithms.

description: In this paper I examine theories of workplace learning in terms of factors that inhibit or support the learning of employees. This will include an examination of the relative influences on workplace learning at three distinct levels: government, institution and the individual. I detail how the possibilities for learning at work depend upon the interrelationship between individual worker dispositions, the affordance of the workplace to provide a restrictive or expansive learning environment, and the influence and direction of government policy. I have demonstrated the importance of the interrelationship of these three tiers of influence and how they cannot be considered in isolation when planning opportunities for teacher learning. I have also argued how there will need to be progression at each of these three stages if teacher learning is to be embedded as part of the fabric and culture of education in the United Kingdom.

description: This study quantifies the possible income and nutritional impact of the recent commitment by the South African Department of Agriculture to increase budgetary spending on agricultural development. Three levels of models are utilized. The first, a large-scale partial equilibrium model, generated an outlook for maize grain under two possible future scenarios; the first is the baseline scenario under which it is assumed no additional government investment in the agricultural sector takes place, the second allows for the impact of an investment within the maize subsector large enough to increase local maize production by 15% above the baseline. The second model, a rational distributed lag model, links the grain sector to the maize meal down-stream market. From this model, the long-run propensity (LRP) was used to determine the long-run change in retail prices given the projected wholesale maize grain prices. These retail price projections where then used to estimate the impact on household expenditure as well as nutritional in-take patterns by utilizing household-level survey data. This study has found if government investment in the maize sector is successful, and results in a 15% increase in production; it could potentially mean cost-savings of approximately R10 per month for the lowest income households.

description: The purpose of this paper is the evaluation of the investment decision under uncertainty and irreversibility allowing for long run inefficiency. The analysis has been applied to a 158 Spanish olive farms using FADN data set. A real option approach has been used to analyse the decision to invest under uncertainty and irreversibility, and a dynamic stochastic frontier model has been developed to estimate the long run technical efficiency and it persistence. The results show that the technical inefficiency persistence parameter is fairly low to unity, which means that small technical inefficiency is transmitted to the next time period. The olive groves investment is irreversible and characterized by uncertainty on price and discount rate. An increase of discount rate means that the farmers take the decision to postpone investment. An increase on price along with a decrease of discount rate leads to the decision to invest with no option value of waiting to invest. The results also suggest that the decision of investment depend on technical inefficiency ant it persistence, the inefficient farmers take time and wait to invest, while at small persistence parameter the decision is to invest.

description: Electrostatic control of the magnetization of a normal mesoscopic conductor is analyzed in a hybrid superconductor-normal-superconductor system. This effect stems from the interplay between the non-equilibrium condition in the normal region and the Zeeman splitting of the quasiparticle density of states of the superconductor subjected to a static in-plane magnetic field. Unexpected spin-dependent effects such as magnetization suppression, diamagnetic-like response of the susceptibility as well as spin-polarized current generation are the most remarkable features presented. The impact of scattering events is evaluated and let us show that this effect is compatible with realistic material properties and fabrication techniques.

description: Bilingual education has been a very controversial issue in the last decade in Colombia because national laws now aim at fostering English–Spanish bilingualism. In particular, it has been evident that special attention has been paid to privileged, urban contexts, leaving aside the realities of disadvantaged and rural areas. This article attempts to raise awareness of critical sociocultural factors involved in the teaching of English in rural areas to understand the complexity of teachers’ professional development considering the particularities of their local work settings. Within the outcomes of this exploration, we found that teachers’ development in rural areas is quite different from that in urban areas. The sociocultural issues in the language classroom frame both teachers’ labour and their professional development needs.

description: Magnetoquasistatic wireless power transfer can be used to charge and power electronic devices such as smartphones and small home appliances. However, existing coil-based transmitters, which are composed of wire conductors, have a limited range. Here we show that multimode quasistatic cavity resonance can provide room-scale wireless power transfer. The approach uses multidirectional, widely distributed currents on conductive surfaces that are placed around the target volume. It generates multiple, mutually unique, three-dimensional magnetic field patterns, where each pattern is attributed to different eigenmodes of a single room-scale resonator. Using these modes together, a power delivery efficiency exceeding 37.1% can be achieved throughout a 3 m * 3 m * 2 m test room. With this approach, power exceeding 50 W could potentially be delivered to mobile receivers in accordance with safety guidelines.

description: We consider the role of the velocity in Lorentz-violating fermionic quantum theory, especially emphasizing the nonrelativistic regime. Information about the velocity will be important for the kinematical analysis of scattering and other problems. Working within the minimal standard model extension, we derive new expressions for the velocity. We find that generic momentum and spin eigenstates may not have well-defined velocities. We also demonstrate how several different techniques may be used to shed light on different aspects of the problem. A relativistic operator analysis allows us to study the behavior of the Lorentz-violating Zitterbewegung. Alternatively, by studying the time evolution of Gaussian wave packets, we find that there are Lorentz-violating modifications to the wave packet spreading and the spin structure of the wave function.

description: We assess long-run patterns of global agricultural productivity growth in developing countries between 1970 and 2005 and examine the relationship between investments in technology capital and productivity. To measure agricultural total factor productivity (TFP) we employ a Solow-type growth accounting method to decompose output growth into input and TFP growth. For technology capital we construct two indexes reflecting national capacities in agricultural research and education-extension for 87 developing countries. We then correlate technology capital levels with long-term growth rates in agricultural TFP. Our findings show that average agricultural TFP growth in developing countries accelerated in the 1980s and 1990s but fell marginally in the early 2000s. TFP performance was very uneven across countries and regions. TFP growth rates by individual countries were significantly influenced by their levels of technology capital. Marginal improvements to research capacity, given a minimal level of extension and schooling existed, were associated with faster TFP growth. However, marginal increases in extension-schooling without commiserate improvements in research capacity did not improve productivity performance.

description: Total travel time $t$ and time delay $Δt$ between images of gravitational lensing (GL) in the equatorial plane of stationary axisymmetric (SAS) spacetimes for null and timelike signals with arbitrary velocity are studied. Using a perturbative method in the weak field limit, $t$ in general SAS spacetimes is expressed as a quasi-series of the impact parameter $b$ with coefficients involving the source-lens distance $r_s$ and lens-detector distances $r_d$, signal velocity $v$, and asymptotic expansion coefficients of the metric functions. The time delay $Δt$ to the leading order(s) were shown to be determined by the spacetime mass $M$, spin angular momentum $a$ and post-Newtonian parameter $γ$, and kinematic variables $r_s,~r_d,~v$ and source angular position $β$. When $β\ll \sqrt{aM}/r_{s,d}$, $Δt$ is dominated by the contribution linear to spin $a$. Modeling the Sgr A* supermassive black hole as a Kerr-Newman black hole, we show that as long as $β\lesssim 1.5\times 10^{-5}$ [$^{\prime\prime}$], then $Δt$ will be able to reach the $\mathcal{O}(1)$ second level, which is well within the time resolution of current GRB, gravitational wave and neutrino observatories. Therefore measuring $Δt$ in GL of these signals will allow us to constrain the spin of the Sgr A*.

Aquatic and terrestrial movements of tailed frogs (ascaphus truei) in relation to timber harvest in Coastal British Columbia
Creators: name: Wahbe, Tanya Rhoda
Publisher: name: University of British Columbia
Year: 2009

description: In British Columbia, Oregon, and California, coastal Ascaphus populations are designated 'at risk.' Local extirpation is a concern because recolonization may be slow, even if post-logging habitats recover quickly. In coastal BC streams flowing through clearcuts, second growth, and old growth, I investigated movements of larval Ascaphus and associations with stream parameters using area-constrained stream surveys. In old growth, larvae moved seven times farther than in clearcuts. Embedded logs, abundant in clearcut streams, may explain shorter larval movements. Using pitfall traps, I examined terrestrial movements of Ascaphus in clearcuts and old growth. More juveniles were trapped in clearcuts but more mature adults were trapped in old growth, suggesting fewer effective migrants in clearcuts. Many frogs moved at least 100 m from streams, and exhibited weaker stream affinity compared to inland Ascaphus that moved at least 12 m. In fall, I trapped frogs farther from streams in old growth than in clearcuts, and more frogs were trapped within 25 m of streams in clearcuts. Long distance overland movements appear more likely where forested stands are present. Using RAPDs, I examined population genetic structure of Ascaphus in an old growth and clearcut stream. In the clearcut, larvae were less diverse than in the old growth and exhibited no relationship between physical distance and genetic relatedness. In the old growth, larvae decreased in genetic similarity with increasing physical distance. Lower heterozygosity in the clearcut suggests that Ascaphus may be less able to adapt to environmental fluctuations and more susceptible to disease than larvae in the old growth. Maintaining viable populations throughout the range of Ascaphus is an underlying assumption of my thesis. My results suggest reduced recolonization potential and lower genetic variation where forest cover is absent. Aggregations of Ascaphus at individual streams may not represent distinct populations, and should not be managed as distinct units. Connectivity between multiple streams within a watershed will be a more meaningful unit of management than individual streams with forested buffers. Conservation measures more likely to promote long-term population persistence should be considered, such as the retention of a partial forest matrix between streams.

description: Using a survey data of 700 traders, this study scrutinizes contract choices and enforcement for agricultural traders in China. This study finds that market service and environment are very important for both contract choices and enforcement. Better market service and environment can increase the propensity of using contract and the probability of contract enforcement both for purchase and sales of products. Education and memberships of special associations are also important for contract choices and enforcement. Higher education and affiliation to special associations for traders can increase the propensity of contracts and reduce contract breaches. However, the formats of contracts, whether contracts are oral or written, are not important for contract enforcement.
