description: Molecules containing superheavy atoms can be artificially created to serve as sensitive probes for study of symmetry-violating phenomena. Here, we provide a detailed theoretical study for diatomic molecules containing the superheavy lawrencium nuclei. The sensitivity to time-reversal violating properties was studied for different neutral and ionic molecules. The effective electric fields in these systems were found to be about 3-4 times larger than other known molecules on which electron electric dipole moment experiments are being performed. Similarly, these superheavy molecules exhibit an enhancement of more than 5 times for parity- and time-reversal-violating scalar-pseudoscalar nucleus-electron interactions. We also briefly comment on some experimental aspects by discussing the production of these systems.

description: Topological dynamics of cellular automata (CA), inherited from classical dynamical systems theory, has been essentially studied in dimension 1. This paper focuses on 2D CA and aims at showing that the situation is different and more complex. The main results are the existence of non sensitive CA without equicontinuous points, the non-recursivity of sensitivity constants and the existence of CA having only non-recursive equicontinuous points. They all show a difference between the 1D and the 2D case. Thanks to these new constructions, we also extend undecidability results concerning topological classification previously obtained in the 1D case.

description: Recent research shows that Hawking radiation can be treated as a quantum tunnelling process, and Hawking temperature of Dirac particles across the horizon of a black hole can be correctly recovered via fermions tunnelling method. In this paper, motivated by fermions tunnelling method, we attempt to apply the analysis to derive Hawking radiation of Dirac particles via tunnelling from black ring solutions of 5-dimensional Einstein-Maxwell-dilaton gravity theory. Finally, it is interesting to find as in black hole cases, fermions tunnelling can also result in correct Hawking temperatures for the rotating neutral, dipole and charged black rings.

description: We present precision calculations of dark radiation in the form of gravitons coming from Hawking evaporation of spinning primordial black holes (PBHs) in the early Universe. Our calculation incorporates a careful treatment of extended spin distributions of a population of PBHs, the PBH reheating temperature, and the number of relativistic degrees of freedom. We compare our precision results with those existing in the literature, and show constraints on PBHs from current bounds on dark radiation from BBN and the CMB, as well as the projected sensitivity of CMB Stage 4 experiments. As an application, we consider the case of PBHs formed during an early matter-dominated era (EMDE). We calculate graviton production from various PBH spin distributions pertinent to EMDEs, and find that PBHs in the entire mass range up to $10^9\,$g will be constrained by measurements from CMB Stage 4 experiments, assuming PBHs come to dominate the Universe prior to Hawking evaporation. We also find that for PBHs with monochromatic spins $a^*>0.81$, all PBH masses in the range $10^{-1}\,{\rm g} < M_{\rm BH} <10^9\,$g will be probed by CMB Stage 4 experiments.

The Photosphere Emission Spectrum of Hybrid Relativistic Outflow for Gamma-ray Bursts

Year: 2021

description: The photospheric emission in the prompt phase is the natural prediction of the original fireball model for gamma-ray burst (GRB) due to the large optical depth ($τ>1$) at the base of the outflow, which is supported by the quasi-thermal components detected in several Fermi GRBs. However, which radiation mechanism (photosphere or synchrotron) dominates in most GRB spectra is still under hot debate. The shape of the observed photosphere spectrum from a pure hot fireball or a pure Poynting-flux-dominated outflow has been investigated before. In this work, we further study the photosphere spectrum from a hybrid outflow containing both a thermal component and a magnetic component with moderate magnetization ($σ_{0}=L_{P}/L_{\text{Th}}\sim 1-10$), by invoking the probability photosphere model. The high-energy spectrum from such a hybrid outflow is a power law rather than an exponential cutoff, which is compatible with the observed Band function in large amounts of GRBs. Also, the distribution of the low-energy indices (corresponding to the peak-flux spectra) is found to be quite consistent with the statistical result for the peak-flux spectra of GRBs best-fitted by the Band function, with similar angular profiles of structured jet in our previous works. Finally, the observed distribution of the high-energy indices can be well understood after considering the different magnetic acceleration (due to magnetic reconnection and kink instability) and the angular profiles of dimensionless entropy with the narrower core.

description: Stylized image captioning systems aim to generate a caption not only semantically related to a given image but also consistent with a given style description. One of the biggest challenges with this task is the lack of sufficient paired stylized data. Many studies focus on unsupervised approaches, without considering from the perspective of data augmentation. We begin with the observation that people may recall similar emotions when they are in similar scenes, and often express similar emotions with similar style phrases, which underpins our data augmentation idea. In this paper, we propose a novel Extract-Retrieve-Generate data augmentation framework to extract style phrases from small-scale stylized sentences and graft them to large-scale factual captions. First, we design the emotional signal extractor to extract style phrases from small-scale stylized sentences. Second, we construct the plugable multi-modal scene retriever to retrieve scenes represented with pairs of an image and its stylized caption, which are similar to the query image or caption in the large-scale factual data. In the end, based on the style phrases of similar scenes and the factual description of the current scene, we build the emotion-aware caption generator to generate fluent and diversified stylized captions for the current scene. Extensive experimental results show that our framework can alleviate the data scarcity problem effectively. It also significantly boosts the performance of several existing image captioning models in both supervised and unsupervised settings, which outperforms the state-of-the-art stylized image captioning methods in terms of both sentence relevance and stylishness by a substantial margin.

description: The Cell Error Rate in simple spreadsheets averages about 2% to 5%. This CER has been measured in domain free environments. This paper compares the CERs occurring in domain free and applied domain tasks. The applied domain task requires the application of simple linear algebra to a costing problem. The results show that domain referent knowledge influences participants' approaches to spreadsheet creation and spreadsheet usage. The conclusion is that spreadsheet error making is influenced by domain knowledge and domain perception. Qualitative findings also suggest that spreadsheet error making is a part of overall human behaviour, and ought to be analyzed against this wider canvas.

Structural and Nucleosynthetic Evolution of Metal-poor and Metal-free Low and Intermediate Mass Stars

description: We report on an investigation into stellar evolution and nucleosynthesis in the low and extremely low metallicity regime, including models of stars with a pure Big Bang composition (i.e. Z=0). The metallicity range of the extremely metal poor (EMP) models we have calculated is -6.5 < [Fe/H] < -3.0, whilst our models are in the mass range 0.85 < M < 3.0 Msun. Many of the EMP and Z=0 models experience violent evolutionary episodes not seen at higher metallicities. We refer to these events as `Dual Flashes' since they are characterised by peaks in the hydrogen and helium burning luminosities occurring at roughly the same time. Some of the material processed by these events is later dredged up by the convective envelope, causing signifcant surface pollution. These events have been reported by previous studies, so our results reaffirm their occurrence -- at least in 1D stellar models. The novelty of this study is that we have calculated the entire evolution of the Z=0 and EMP models, from the ZAMS to the end of the TPAGB, including detailed nucleosynthesis. We have also calculated the nucleosynthetic yields, which will soon be available in electronic format. Although subject to many uncertainties these are, as far as we are aware, the only yields available in this mass and metallicity range. In this paper we briefy describe some of the results in the context of abundance observations of EMP halo stars. This work formed part of SWC's PhD thesis (completed in March 2007) and a series of subsequent papers will describe the results of the study in more detail.

description: Electronic structures of SiC nanoribbons have been studied by spin-polarized density functional calculations. The armchair nanoribbons are nonmagnetic semiconductor, while the zigzag nanoribbons are magnetic metal. The spin polarization in zigzag SiC nanoribbons is originated from the unpaired electrons localized on the ribbon edges. Interestingly, the zigzag nanoribbons narrower than $\sim$4 nm present half-metallic behavior. Without the aid of external field or chemical modification, the metal-free half-metallicity predicted for narrow SiC zigzag nanoribbons opens a facile way for nanomaterial spintronics applications.

The mesoscale variability of insolation over the Lower Fraser Valley resolved by geostationary satellite data
Creators: name: Benchimol, Nicole
Publisher: name: University of British Columbia
Year: 2010

description: Assessments of the mesoscale variability of the insolation over the lower Fraser Valley have been hampered by the inadequate spatial resolution of the available pyranometric data. At present, the establishment of a dense ground-based observing network is economically infeasible. The adaptation of geostationary satellite data for estimating insolation is an attractive alternative. The ability of a simple physically-based model (Gautier et al., 1980) to resolve the hourly mesoscale insolation variability is evaluated. The satellite-based estimates are shown to be more coherent than the observed insolation. Discrepancies are attributed to the spatial averaging inherent in the satellite methodology. The estimates are found to be insensitive to spatial averaging down to a 3 x 3 pixel (about 13 km₂ ) scale. The effects of spatial averaging are believed to occur at smaller spatial scales. The satellite-based estimates generally display a good correspondence with the observed insolation. Maps of the mean hourly estimated insolation are obtained with a high degree of accuracy due to small systematic modelling errors. The inability of the model to distinguish between snow and cloud, and its sensitivity to variations in surface albedo introduce artifacts in maps of the clear sky insolation. On the other hand, the mesoscale variability of individual hourly fields cannot be resolved using 'the satellite-based approach. Errors for these estimates are so large that they obscure the variability of the insolation field. The usefulness of the mapping procedure appears to be limited to assessments of the average insolation.

Gamma-Ray Burst high energy emission from Internal Shocks

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

description: In this paper we study synchrotron and synchrotron self Compton (SSC) emission from internal shocks (IS) during the prompt and X-ray flare phases of Gamma-Ray Bursts (GRBs). The aim is to test the IS model for the flare emission and for whether GRBs can be GeV sources. We determine the parameters for which the IS model can account for the observed prompt and X-ray flares emission, and study the detectability of the high energy SSC emission by the AGILE and GLAST satellites. We find that the detectability of the SSC emission during the prompt phase of GRBs improves for higher values of the fireball Lorentz factor and of the temporal variability. If IS is the mechanism responsible of the flare emission, and the Lorentz factor of the shells producing the flare is of the order of 100, the flare light curves are expected to present some substructures with temporal variability of 10-100 ms which are much smaller than the average duration of flares, and similar to those observed during the prompt phase of GRBs. If one assumes lower Lorentz factors, such as 10-25, then a larger temporal variaibility of 40 s can also account for the observed flare properties. However in this case we predict that X-ray flares do not have a counterpart at very high energies (MeV-GeV). An investigation on the substructures of the X-ray flares light curves, and simultaneous X-ray and high energy observations, will allow us to corroborate the hypothesis that late IS are responsible of the X-ray flares.

Demystifying statistical learning based on efficient influence functions

description: Evaluation of treatment effects and more general estimands is typically achieved via parametric modelling, which is unsatisfactory since model misspecification is likely. Data-adaptive model building (e.g. statistical/machine learning) is commonly employed to reduce the risk of misspecification. Naive use of such methods, however, delivers estimators whose bias may shrink too slowly with sample size for inferential methods to perform well, including those based on the bootstrap. Bias arises because standard data-adaptive methods are tuned towards minimal prediction error as opposed to e.g. minimal MSE in the estimator. This may cause excess variability that is difficult to acknowledge, due to the complexity of such strategies. Building on results from non-parametric statistics, targeted learning and debiased machine learning overcome these problems by constructing estimators using the estimand's efficient influence function under the non-parametric model. These increasingly popular methodologies typically assume that the efficient influence function is given, or that the reader is familiar with its derivation. In this paper, we focus on derivation of the efficient influence function and explain how it may be used to construct statistical/machine-learning-based estimators. We discuss the requisite conditions for these estimators to perform well and use diverse examples to convey the broad applicability of the theory.
Evaluation of specific heat for superfluid helium between 0 - 2.1 K based on nonlinear theory

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: The specific heat of liquid helium was calculated theoretically in the Landau theory. The results deviate from experimental data in the temperature region of 1.3 - 2.1 K. Many theorists subsequently improved the results of the Landau theory by applying temperature dependence of the elementary excitation energy. As well known, many-body system has a total energy of Galilean covariant form. Therefore, the total energy of liquid helium has a nonlinear form for the number distribution function. The function form can be determined using the excitation energy at zero temperature and the latent heat per helium atom at zero temperature. The nonlinear form produces new temperature dependence for the excitation energy from Bose condensate. We evaluate the specific heat using iteration method. The calculation results of the second iteration show good agreement with the experimental data in the temperature region of 0 - 2.1 K, where we have only used the elementary excitation energy at 1.1 K.

description: The Fermi acceleration model was introduced to describe how cosmic ray particles are accelerated to great speeds by interacting with moving magnetic fields. We identify a new variation of the model where light ions interact with a moving wall while undergoing pitch angle scattering through Coulomb collisions due to the presence of a heavier ionic species. The collisions introduce a stochastic component which adds complexity to the particle acceleration profile and sets it apart from collisionless Fermi acceleration models. The unusual effect captured by this simplified variation of Fermi acceleration is the non-conservation of phase space, with the possibility for a distribution of particles initially monotonically decreasing in energy to exhibit an energy peak upon compression. A peaked energy distribution might have interesting applications, such as to optimize fusion reactivity or to characterize astrophysical phenomena that exhibit non-thermal features.

description: We consider the problem of diffusion-controlled evolution of the system $A$-particle island - $B$-particle island at propagation of the sharp annihilation front $A+B\to 0$. We show that this general problem, which includes as particular cases the sea-sea and the island-sea problems, demonstrates rich dynamical behavior from self-accelerating collapse of one of the islands to synchronous exponential relaxation of the both islands. We find a universal asymptotic regime of the sharp front propagation and reveal limits of its applicability for the cases of mean-field and fluctuation fronts.

description: Casimir energy is calculated in the 5D warped system. It is compared with the flat one. The position/ momentum propagator is exploited. A new regularization, called {\it sphere lattice regularization}, is introduced. It is a direct realization of the geometrical interpretation of the renormalization group. The regularized configuration is closed-string like. We do {\it not} take the KK-expansion approach. Instead the P/M propagator is exploited, combined with the heat-kernel method. All expressions are closed-form (not KK-expanded form). Rigorous quantities are only treated (non-perturbative treatment). The properly regularized form of Casimir energy, is expressed in the closed form. We numerically evaluate its $\La$(4D UV-cutoff), $\om$(5D bulk curvature, warpedness parameter) and $T$(extra space IR parameter) dependence.

The estimation of economic depreciation for Canadian farm machinery
Creators: name: Bell, Paul Kevin Thomas
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this thesis was to estimate the rate at which four types of farm machinery lose value in Canada. Specifically, Canadian data on used machinery prices was utilized to produce estimates of economic depreciation for two-wheel-drive tractors, combines, square balers and large round balers. The data used in this thesis to make these estimates are special for two reasons. First of all, they represent the only extensive record of Canadian used farm equipment prices available. Most previous studies have based their estimates on American data, assuming that they apply equally well to the Canadian situation. Secondly, these data record actual transactions in the used market and these transactions have been reported in an unaveraged format. This is valuable because information on options, horsepower, condition, and, most importantly, hours of use was retained for each machine. The availability of this information permitted richer and more specific estimates of depreciation. In particular, the inclusion of hours of use in the models enabled a distinction to be made in this thesis between the component of depreciation which is directly attributable to age and that component which is directly attributable to accumulated hours of use. It is felt that this distinction provides a beginning point for the study of depreciation due to simple "wear and tear", and that depreciation which is due to obsolescence and technological change. As well, this thesis extensively reviewed the literature on depreciation in an effort to determine the best approach to follow. The method finally adopted was the "remaining value approach"; however, the thesis went further than the typical remaining value approach because an attempt was made to estimate the pattern as well as the rate of depreciation. This was done by initially adopting a functional form which was flexible enough to let the data "choose for themselves" between the commonly used depreciation rules of thumb (declining balance, straight-line and one-hoss-shay patterns). This was possible by using the Box-Tidwell procedure. This Box-Tidwell procedure when applied to the extensive tractor data indicated that tractors in Canada follow a declining balance (geometric) pattern of depreciation. This was taken as support for the adoption of semi-log models to estimate depreciation. The main findings of this thesis are, first, that depreciation rates vary among assets (from approximately 9% for tractors to nearly 16% for large round balers), and, secondly, that these rates are less than those allowed by the government for tax purposes. It was concluded that this generosity on the part of the government would be acceptable if it applied equally to all depreciable assets, but the divergence in depreciation rates found in this thesis indicate that generous blanket depreciation charges give more advantage to some than to others.

description: The linear stability of closed timelike geodesics (CTGs) is analyzed in two spacetimes with cylindrical sources, an infinite rotating dust cylinder, and a cylindrical cloud of static cosmic strings with a central spinning string. We also study the existence and linear stability of closed timelike curves in spacetimes that share some common features with the Gödel universe (Gödel-type spacetimes). In this case the existence of CTGs depends on the `background' metric. The CTGs in a subclass of inhomogeneous stationary cosmological solutions of the Einstein-Maxwell equations with topology $ S^3\times \mathbb R$ are also examined.

description: Mit der Strafverfolgungsstatistik werden die im Laufe eines Jahres auf Grund gerichtlicher Entscheidung rechtskräftig abgeurteilten und verurteilten Personen erfasst. Von den Amtsgerichten und Staatsanwaltschaften werden die Daten von Personen, die sich wegen Verbrechen oder Vergehen nach dem Strafgesetzbuch, nach anderen Bundesgesetzen oder nach Landesrecht einschließlich der Straftaten im Straßenverkehr vor Gericht verantworten mussten, in anonymisierter Form an das Statistikamt Nord weitergeleitet. Dabei werden Abgeurteilte und Verurteilte nach allgemeinem Strafrecht und nach Jugendstrafrecht unterschieden. Ordnungswidrigkeiten werden in dieser Statistik nicht erfasst. Die Statistik basiert auf Datensätzen und Zählkarten, die von den Gerichten für jede rechtskräftige Aburteilung erstellt werden. Bei der Aburteilung von Straftaten, die in Tateinheit oder Tatmehrheit begangen wurden, ist nur die Straftat erfasst, die nach dem Gesetz mit der schwersten Strafe bedroht ist. Werden mehrere Straftaten einer Person in mehreren Verfahren abgeurteilt, wird diese Person entsprechend mehrfach gezählt. In der Strafvollzugsstatistik werden zum Stichtag 31.03. jeden Jahres die Strafgefangenen und Sicherungsverwahrten nach ausgewählten demographischen und kriminologischen Merkmalen erfasst. Untersuchungs- und Abschiebehäftlinge bleiben bei dieser Stichtageserhebung unberücksichtigt.

description: We employ a stochastic dominance (SD) approach to analyze the components that contribute to environmental degradation over time. The variables that are considered include countries’ greenhouse gas (GHG)
emissions and water pollution. Our approach is based on pair-wise SD tests. First, we study the dynamic
progress of each separate variable over time, from 1990 to 2005, within 5-year horizons. Then, pair-wise SD
tests are used to study the major industry contributors to the overall GHG emissions and water pollution at
any given time, to uncover the industry which contributes the most to total emissions and water pollution.
We find that CO2 emissions not only contribute the most to the GHG emissions over time, but also increased
within 15 year in the first-order SD sense. On the other hand, water pollution increased in a second-order SD
sense. Pair-wise industry comparisons suggest that the major industry contributors to the CO2 emissions
have always been the electricity and heat production sectors, while the transport sector has been the second
contributor between 1990 and 2005. Finally, the food industry gradually became the major contributing
industry for water pollution over time.
Complete State Reconstruction of a Two-Mode Gaussian State via Local Operations and Classical Communication

description: We propose a strictly local quantum tomography protocol for a bipartite system. We show that the joint density matrix of an arbitrary two-mode Gaussian state, entangled or not, is obtained via local operations and classical communication only. In contrast to previous proposals, simultaneous homodyne measurements (HM) on both modes are replaced by local homodyne detections and a set of local projective measurements.

Gamma-Ray Emission from PWNe Interacting with Molecular Clouds

description: We consider a situation in which a pulsar (and its nebula) is formed inside or close to a high density regions of a molecular cloud. We apply a recent model for the gamma radiation of pulsar wind nebulae (PWN), which includes not only radiation processes due to injected leptons but also processes due to injection of relativistic hadrons, in order to calculate the expected gamma-ray emission from such interacting PWNe. The example calculations have been performed for two objects of this type from which directions TeV gamma-ray sources have recently been observed (IC443 and W41). We show that the gamma-ray emission below a few TeV can be produced by leptons accelerated in the past in the vicinity of the pulsars. gamma-rays with energies above ~10 TeV can be produced by hadrons interacting with the matter inside the supernova remnant and surrounding dense clouds. In contrary to the low energy TeV emission, this high energy TeV emission should be correlated with the location of dense clouds able to capture hadrons due to their strong magnetic fields.
