description: Superstring compactifications have been vigorously studied for over four decades, and have flourished involving an active iterative feedback between physics and (complex) algebraic geometry. This led to an unprecedented wealth of constructions, virtually all of which are "purely" algebraic. Recent developments however indicate many more possibilities to be afforded by including certain generalizations that, at first glance at least, are not algebraic -- yet fit remarkably well within an overall mirror-symmetric framework and are surprisingly amenable to standard computational analysis upon certain mild but systematic modifications.

description: The creation of collective many-body quantum states from a two-dimensional lattice gas of atoms is studied. Our approach relies on the van-der-Waals interaction that is present between alkali metal atoms when laser excited to high-lying Rydberg s-states. We focus on a regime in which the laser driving is strong compared to the interaction between Rydberg atoms. Here energetically low-lying many-particle states can be calculated approximately from a quadratic Hamiltonian. The potential usefulness of these states as a resource for the creation of deterministic single-photon sources is illustrated. The properties of these photon states are determined from the interplay between the particular geometry of the lattice and the interatomic spacing.

Gravitational Collapse, Negative World and Complex Holism

Year: 2010
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Building on the engine-pump paradigm of ChaNoXity, this paper argues that complex holism - as the competitive homeostasis of dispersion and concentration - is the operating mode of Nature. Specifically, we show that the negative world \mathfrak{W} is a gravitationally collapsed black hole that was formed at big-bang time t=0 as the pair (W,\mathfrak{W}), with W a real world, and gravity the unique expression of the maximal multifunctional nonlinearity of the negative world \mathfrak{W} in the functional reality of W. The temperature of a gravitationally collapsed system does enjoy the relationship T\propto1/r with its radius, but the entropy follows the usual volumetric alignment with microstates, reducing to the surface approximation only at small r. It is not clear if quantum non-locality is merely a linear manifestation of complex holism, with the interaction of quantum gates in quantum entanglements resulting in distinctive features from the self-evolved structures of complex holism remaining an open question for further investigation

description: Formulas for the combined nuclear-recoil and finite-nuclear-size effects of order $(Z\,α)^5$ and $(Z\,α)^6$ are derived without any expansion in the nuclear charge radius $r_C$, making them applicable to both electronic and muonic atoms. The obtained results are particularly relevant for high-precision determinations of root-mean-square charge radii from muonic atom spectroscopy. We demonstrate that calculations of the atomic isotope shift based on the widely used Breit approximation give rise to an unphysical nuclear-size contribution that is linear in the nuclear charge radius $r_C$ at order $(Z\,α)^5$. This spurious term vanishes in a full QED treatment, leaving the correct contribution quadratic in $r_C$. For electronic atoms, this quadratic term is significantly smaller than the spurious linear contribution.

description: The late-stage evolution of massive stars is marked by intense instability as they approach core-collapse. During these phases, giant stellar eruptions lead to exceptionally high mass-loss rates, forming significant amounts of dust. However, the survival of these dust grains is challenged by the powerful shock waves generated when the progenitor explodes as a supernova (SN). We explore the impact of hydrogen-rich SN explosions from 45, 50, and 60 M$_\odot$ progenitors on dust formed after these eruptions, focusing on interactions with circumstellar shells occurring from a few years to centuries after the event. Using 3D hydrodynamical simulations, we track the evolution of dust particles in a scenario that includes the progenitor's stellar wind, a giant eruption, and the subsequent SN explosion, following the mass budgets predicted by stellar evolution models. For a standard SN ejecta mass of 10 M$_\odot$ and kinetic energy of $10^{51}$ erg, only 25% of the dust mass survives 250 years post-explosion in a spherical circumstellar medium (CSM), while merely 2% remains a century after the explosion in a bipolar CSM. If the SN follows the eruption within a dozen years, 75% of the dust survives for a standard explosion, dropping to 20% for more massive ejecta (15-20 M$_\odot$) with kinetic energy of $5 \times 10^{51}$ erg. The geometry of the CSM and the early transition of the SN remnant into a radiative phase significantly influence dust survival. As the shock wave weakens and efficiently converts kinetic energy into thermal radiation (up to half of the injected kinetic energy) the likelihood of dust survival increases, affecting not only pre-existing dust in the CSM but also SN-condensed dust and ambient interstellar dust. Contrary to expectations, a larger fraction of the dust mass can survive if the SN occurs only a few years after the eruption.

description: The article presents the results of the study of the effectiveness of business communication in the process of providing services by the company. Using the example of a specific situation that occurred at United Airlines in 2017, we conducted a utilitarian analysis of the behavior of stakeholders from the standpoint of business law and business ethics. The hypothesis of the study was the assumption that violation of business ethics in the process of resolving conflicts has an adverse impact on the company’s image in the long term. The utilitarian analysis has been used as a research method. As the result of the study, recommendations have been formulated for resolving the conflict situation

description: Several technical aspects concerning the evaluation of the overlap between two mean field wave functions of the Hartree Fock Bogoliubov type, are discussed. The limit when several orbitals become fully occupied is derived as well as the formula to reduce the dimensionality of the problem when exactly empty orbitals are present. The formalism is also extended to deal with the case where the bases of each of the wave functions are different. Several practical results concerning the evaluation of pfaffians as well as the canonical decomposition of norm overlaps are also discussed in the appendices.

description: The receiver operating characteristic (ROC) curve is widely used to assess discriminative accuracy of two groups based on a continuous score. In a variety of applications, the distributions of such scores across the two groups exhibit a stochastic ordering. Specific examples include calibrated biomarkers in medical diagnostics or the output of matching algorithms in biometric recognition. Incorporating stochastic ordering as an additional constraint into estimation can improve statistical efficiency. In this article, we consider modeling of ROC curves using both the order constraint and covariates associated with each score given that the latter (e.g., demographic characteristics of the underlying subjects) often have a substantial impact on discriminative accuracy. The proposed method is based on the indirect ROC regression approach using a location-scale model, and quadratic optimization is used to implement the order constraint. The statistical properties of the proposed order-constrained least squares estimator are studied. Based on the theoretical results developed herein, we deduce that the proposed estimator can achieve substantial reductions in mean squared error relative to its unconstrained counterpart. Simulation studies corroborate the superior performance of the proposed approach. Its practical usefulness is demonstrated in an application to face recognition data from the “Good, Bad, and Ugly” face challenge, a domain in which accounting for covariates has hardly been studied.

The benefits to hiring individuals with intellectual disabilities : employers' perspectives
Creators: name: Wells, Taylor Charlene
Publisher: name: University of British Columbia
Year: 2018

description: Many individuals with Intellectual Disabilities (ID) desire meaningful community participation and are motivated to work. Despite this desire, employment rates for people with ID are considerably low. Negative employer attitudes are one of the main barriers faced by individuals with ID in securing competitive integrated employment. Employers who have had one and a half- to 30 years’ experience hiring employees with ID were interviewed on the benefits to hiring and retaining workers with ID. The sample included 13 employers and 2 additional workplace managers, totalling 15 participants. Four major findings emerged that describe the benefits to hiring people with ID: 1) Workplace Environment, 2) Business, 3) Employer Job Satisfaction, and 4) Community Support and Expertise. Hiring employees with ID led to a more positive workplace environment, bolstered by the employees’ personalities, contributing to a sense of teamwork and employer perspective shift on workplace operations. Employees with ID contributed to better business by filling roles, demonstrating strong work ethics and bringing diversity to the workforce. Employers experienced greater job satisfaction in knowing that they were making a difference by hiring inclusively and connecting to the community. Finally, employers commented on the benefits of community support professionals who assist with hiring, training and retaining employees with ID. One of the primary goals of the present study was to educate employers on the benefits to hiring people with ID. Study participants’ advice to more hesitant employers and further dissemination of results are discussed. No one who wants to work, should be excluded from the labour market, and with the right assessment, tools, support, and welcoming employers, this is achievable.
Biophysical investigation of leukocyte rolling adhesion at the single cell level
Creators: name: Murad, Yousif
Publisher: name: University of British Columbia

description: Cell rolling adhesion is a mode of passive directional migration under flow used by a variety of prokaryotic as well as eukaryotic cells. Leukocytes have been shown to make use of rolling adhesion in the inflammatory response by rolling along the endothelial cells covering blood vessel walls to find their target site. This process is mediated by a family of adhesion proteins called selectins. One selectin of interest to us, P-selectin, is expressed on the surface of endothelial cells and interacts with P-selectin glycoprotein ligand-1 (PSGL-1) on the surface of rolling leukocytes. This interaction is made of non-covalent interactions such as hydrogen bonds, van der Waals interactions and electrostatic interactions. Leukocyte rolling adhesion has been investigated by many groups in the literature using flow chambers. These studies have made use of a variety of methods to functionalize a glass surface with P-selectin (or any selectin of interest). Such methods have focused on passivating the surface with human vein endothelial cell (HUVECs) or with bovine serum albumin (BSA). Neither method has been shown to provide a homogenous surface of P-selectin of known density in the absence of any other protein interactions. These studies have also mainly focused on cell rolling at the population level and how it is affected by shear stress and receptor surface density amongst other factors. In this thesis, polyethylene glycol (PEG), a polymer used in surface passivation for single molecule studies, is adapted to create a well control surface of P-selectin and to exclude any other proteins from adsorbing to the surface. Our data has shown the many key features of cell rolling behavior are disguised or significantly distorted when looking at the overall population behavior. This leads us to direct our effort towards in-depth single cell biophysical studies thus eliminating the influence of cell-to-cell variability and different phenotypic traits. Here, we used precision-controlled syringe pumps to vary shear stress patterns affecting single cells in a rationally designed barrage of shear ramp and oscillation experiments with the purpose of unmasking previously unseen cell rolling behavior.

description: Functional linear regression is a widely used approach to model functional responses with respect to functional inputs. However, classical functional linear regression models can be severely affected by outliers. We therefore introduce a Fisher-consistent robust functional linear regression model that is able to effectively fit data in the presence of outliers. The model is built using robust functional principal component and least squares regression estimators. The performance of the functional linear regression model depends on the number of principal components used. We therefore introduce a consistent robust model selection procedure to choose the number of principal components. Our robust functional linear regression model can be used alongside an outlier detection procedure to effectively identify abnormal functional responses. A simulation study shows our method is able to effectively capture the regression behavior in the presence of outliers, and is able to find the outliers with high accuracy. We demonstrate the usefulness of our method on jet engine sensor data. We identify outliers that would not be found if the functional responses were modeled independently of the functional input, or using nonrobust methods.

description: The receiver operating characteristic (ROC) curve is widely used to assess discriminative accuracy of two groups based on a continuous score. In a variety of applications, the distributions of such scores across the two groups exhibit a stochastic ordering. Specific examples include calibrated biomarkers in medical diagnostics or the output of matching algorithms in biometric recognition. Incorporating stochastic ordering as an additional constraint into estimation can improve statistical efficiency. In this article, we consider modeling of ROC curves using both the order constraint and covariates associated with each score given that the latter (e.g., demographic characteristics of the underlying subjects) often have a substantial impact on discriminative accuracy. The proposed method is based on the indirect ROC regression approach using a location-scale model, and quadratic optimization is used to implement the order constraint. The statistical properties of the proposed order-constrained least squares estimator are studied. Based on the theoretical results developed herein, we deduce that the proposed estimator can achieve substantial reductions in mean squared error relative to its unconstrained counterpart. Simulation studies corroborate the superior performance of the proposed approach. Its practical usefulness is demonstrated in an application to face recognition data from the “Good, Bad, and Ugly” face challenge, a domain in which accounting for covariates has hardly been studied.

description: This work examines a stochastic volatility model with double-exponential jumps in the context of option pricing. The model has been considered in previous research articles, but no thorough analysis has been conducted to study its quality of calibration and pricing capabilities thus far. We provide evidence that this model outperforms challenger models possessing similar features (stochastic volatility and jumps), especially in the fit of the short term implied volatility smile, and that it is particularly tractable for the pricing of exotic options from different generations. The article utilizes Fourier pricing techniques (the PROJ method and its refinements) for different types of claims and several generations of exotics (Asian options, cliquets, barrier options, and options on realized variance), and all source codes are made publicly available to facilitate adoption and future research. The results indicate that this model is highly promising, thanks to the asymmetry of the jumps distribution allowing it to capture richer dynamics than a normal jump size distribution. The parameters all have meaningful econometrics interpretations that are important for adoption by risk-managers.

description: Excerpts from the report: In modified atmosphere environments, where carbon dioxide (CO2) concentration is increased and oxygen (O2) is reduced, yellowing of broccoli is greatly retarded. One method of obtaining a modified atmosphere that might be beneficial at certain temperatures is to package the commodity in sealed film. A study showed that broccoli was a good prepackaging prospect. Although off-odor accumulated in 2 days at 20° C in the nonperforated packages, it dissipated rapidly after opening. Packaging with Pliofilm, cellophane, and cellulose acetate has been tested as a supplement to refrigeration for maintaining good broccoli quality. Overwrapping broccoli bunches with a shrink film at the shipping point has also been tried. The present study was conducted to determine the effect of consumer packaging with perforated and sealed polyethylene film and holding at different temperatures on the keeping quality and subsequent shelf life of broccoli.

description: We present detailed studies of the coherence properties of an ultra-broadband super-continuum, enabled by a new approach involving continuous wave laser sources to independently probe both the amplitude and phase noise quadratures across the entire spectrum. The continuum coherently spans more than 1.5 octaves, supporting Hz-level comparison of ultrastable lasers at 698 nm and 1.54 μm. We present the first numerical simulation of the accumulated comb coherence in the limit of many pulses, in contrast to the single-pulse level, with systematic experimental verification. The experiment and numerical simulations reveal the presence of quantum-seeded broadband amplitude noise without phase coherence degradation, including the discovery of a dependence of the super-continuum coherence on the fiber fractional Raman gain.

description: Star formation through the dynamical magnetized collapse remains an active area of astrophysical research. We carry out a comprehensive exploration on the magnetized gravitational collapse of a non-rotating self-gravitating initially spherically symmetric prestellar cloud core using two-dimensional nonideal magnetohydrodynamic simulations incorporating ambipolar diffusion and Ohmic dissipation. Our study encompasses a broader range of equations of state (EOSs) in the form of $P(ρ) \propto ρ^Γ$, with the aim of constraining the choice of EOSs for allowing star formation. Our results reveal that the collapse with a $Γ$ no stiffer than $4/3$, complemented by magnetized virial theorem, allows the dynamical contraction of the prestellar core to happen continuously where a central point mass forms and steadily builds up its mass from the infalling envelope, with a mass accretion rate of a scale of the order of $c_{\rm s}^3/G$. The choice of an isothermal EOS most naturally facilitates the collapse as a magnetic analog of the inside-out collapse. In addition to that, our study exhibits that the nonisothermal magnetized collapse models with a $Γ$ no stiffer than 4/3 qualitatively demonstrate similar infall features to those of an isothermal EOS. Furthermore, the collapse models with a $Γ$ stiffer than $4/3$ fail to ensure the sufficient cooling to allow the direct mass growth of the central point mass, thus delaying the infall. Our work can offer deeper insights in understanding the significance of EOSs on the magnetized gravitational collapse, enabling star formation.

description: The D3/D7 system holographically describes an N=2 gauge theory which spontaneously breaks a chiral symmetry by the formation of a quark condensate in the presence of a magnetic field. At finite temperature it displays a first order phase transition. We study out of equilibrium dynamics associated with this transition by placing probe D7 branes in a geometry describing a boost-invariant expanding or contracting plasma. We use an adiabatic approximation to track the evolution of the quark condensate in a heated system and reproduce the phase structure expected from equilibrium dynamics. We then study solutions of the full partial differential equation that describes the evolution of out of equilibrium configurations to provide a complete description of the phase transition including describing aspects of bubble formation.

description: We develop a rigorous formalism for the description of the evolution of states of quantum many-particle systems in terms of a one-particle density operator. For initial states which are specified in terms of a one-particle density operator the equivalence of the description of the evolution of quantum many-particle states by the Cauchy problem of the quantum BBGKY hierarchy and by the Cauchy problem of the generalized quantum kinetic equation together with a sequence of explicitly defined functionals of a solution of stated kinetic equation is established in the space of trace class operators. The links of the specific quantum kinetic equations with the generalized quantum kinetic equation are discussed.

Detection of [C I] Emission in Nebular Spectra of a Peculiar Type Ia Supernova 2022pul

description: SN 2022pul gains special attention due to its possible origin of a super-Chandarsekhar-mass white dwarf explosion (or called a 03fg-like type Ia supernova), which shows prominent [O I], [Ne II], and [Ca II] lines in its late-time spectra taken at $\sim+$300 days after the peak brightness. In this paper, we present new optical observations for this peculiar object, extending up to over 500 days after the peak brightness. In particular, in the $t\approx+515$ days spectrum, we identified for the first time the presence of narrow emission from [C I] $λ\lambda9824, 9850$, which appears asymmetric and quite similar to the accompanied [O I] $\lambda6300$ line in strength and profile. Based on the violent merger model that accounts well for previous observations but leaves little carbon in the center of the ejecta, this carbon line can be reproduced by increasing the degree of clumping in the ejecta and setting the carbon mass the same as that of oxygen ($\sim$0.06 $M_{\odot}$) in the innermost region ($\lesssim 2000$ km s$^{-1}$). In principle, the central carbon could come from the secondary white dwarf (WD) if it is ignited when hit by the shockwave of the explosion of the primary WD and explodes as a Ca-rich supernova, whereas pure deflagration of a super-Chandarsekhar-mass WD can account for such unburnt carbon more naturally.

Deliberating climate change mitigation options and policies in British Columbia’s forests
Creators: name: Peterson St-Laurent, Guillaume
Publisher: name: University of British Columbia
Year: 2018

description: Global efforts are urgently needed to mitigate climate change, which involves changing business-as-usual activities to reduce greenhouse gases emissions and increase removals of carbon from the atmosphere. Because of their role as carbon sinks, forests offer climate mitigation potential when and if they are managed effectively. The role of forest management in mitigating climate change is a central concern for the Canadian province of British Columbia (BC). The province faces a decision context where publicly owned forests occupy 60% of the land base and the role of forests in mitigating climate change is scientifically established and politically acknowledged. At the same time, a policy gap exists and little is known in terms of public opinion on forest carbon mitigation options and policy. Drawing upon the idea that any future forest carbon management activities and policies will require strong public and political support and acceptability, I seek to identify what are BC’s public and stakeholders’ perceptions on advantages and issues associated with existing and prospective mitigation options in the forests. First, I analyze the extent of policy change brought by the Forest Carbon Offset Protocol, which until 2016 was one of the only significant forest carbon policy options in BC. I conclude that while policy changes occurred, notably by allowing for offset projects, the extent of these changes is limited by numerous barriers. Second, I explore these barriers and provide recommendations for the future uptake of forest carbon offset. Third, I describe the result of an online survey of BC’s general public that indicates overall support for eight different forest mitigation options, with greater preference for rehabilitation and conservation-focused strategies. Fourth I report on the result of an extensive analytic-deliberative engagement process with stakeholders and indigenous people across BC where participants indicated support for six mitigation strategies, with high consensus between regions and sectoral groups. Fifth, I evaluate the analytic-deliberative process and provide recommendations for the design of similar methodologies. The dissertation concludes that, notwithstanding apparent differences in preferences and priorities, an opportunity exists to move forward with a set of comprehensive, multi-faceted forest carbon mitigation actions and policies.
Lyra's Cosmology of Massive String in Anisotropic Bianchi-II Space-time

description: The paper deals with a spatially homogeneous and totally anisotropic Bianchi II cosmological models representing massive strings in normal gauge for Lyra's manifold. The modified Einstein's field equations have been solved by applying variation law for Hubble's parameter. This law generates two type of solutions for average scale factor, one is of power law type and other is of exponential law type. The power law describes the dynamics of Universe from big bang to present epoch while exponential law seems reasonable to project dynamics of future Universe. It has been found that the displacement actor $(β)$ is a decreasing function of time and it approaches to small positive value at late time, which is collaborated with Halford (1970) as well as recent observations of SN Ia. The study reveals that massive strings dominate in early Universe and eventually disappear from Universe for sufficiently large time, which is in agreement with the current astronomical observations.

description: By employing two-color counter-rotating circularly polarized laser fields, we investigate the dynamics of electron recapture into Rydberg states under strong, ultrashort laser pulses, probed via coherent extreme-ultraviolet free-induction decay (XFID). Our study reveals significant distinctions between XFID and above-threshold high-order harmonic generation in terms of their ellipticity dependence on the driving-laser waveforms, yield variations with the laser-intensity ratios, and sensitivity to the driving-laser ellipticity. All these differences arise from the fundamentally distinct electron trajectories underlying the two processes. More importantly, our findings provide compelling evidence that Rydberg-electron recapture predominantly occurs at the end of the driving laser field, offering the first direct experimental confirmation of this long-proposed mechanism.
