description: A general construction principle of inflation rules for decagonal quasiperiodic tilings is proposed. The prototiles are confined to be polygons with unit edges. An inflation rule for a tiling is the combination of an expansion and a division of the tiles, where the expanded tiles can be divided arbitrarily as far as the set of prototiles is maintained. A certain kind of point decoration processes turns out to be useful for the identification of possible division rules. The method is capable of generating a broad range of decagonal tilings, many of which are chiral and have atomic surfaces with fractal boundaries. Two new families of decagonal tilings are presented; one is quarternary and the other ternary. Properties of the ternary tilings with rhombic, pentagonal, and hexagonal prototiles are investigated in detail.

description: We derive backward and forward fractional Schrödinger type of equations for the distribution of functionals of the path of a particle undergoing anomalous diffusion. Fractional substantial derivatives introduced by Friedrich and co-workers [PRL {\bf 96}, 230601 (2006)] provide the correct fractional framework for the problem at hand. In the limit of normal diffusion we recover the Feynman-Kac treatment of Brownian functionals. For applications, we calculate the distribution of occupation times in half space and show how statistics of anomalous functionals is related to weak ergodicity breaking.

Integrated primary care in Canada : examining the effectiveness of an adapted online-training curriculum among training psychologists
Creators: name: Iyar, Megumi M.

description: Mental health concerns among Canadians are common, and primary care settings are often considered the first point of contact in addressing these issues. Despite the increased interest and the growing body of literature demonstrating the benefits of collaboration between medicine and psychology, the integration of these fields in primary care settings is limited. There is some research to suggest that increasing education and training in integrated primary care can foster interest among psychology trainees and can facilitate collaboration between disciplines– however there is a gap in the availability of empirically validated training curriculums tailored to the specifics of Canadian health care. The purpose of the present study was to evaluate the impact of implementing an adapted brief-online training curriculum on integrated primary care for psychology graduate trainees in Canada. The aim was to determine whether a brief-online training curriculum was an effective means to increase interest, attitudes, and understanding of integrated primary care. Sixty-six graduate students (Mage = 29.41, SD = 5.42) currently enrolled in a professional psychology graduate program participated in the training. Participants completed measures prior to the start of the adapted-online curriculum. Once baseline measures were completed, access to the brief-online curriculum was provided. Following successful completion of the online curriculum, participants were asked to complete post-training study measures. The results of the present study showed that the implementation of an adapted brief-online training increased psychology trainees’ interest, and their perceived and actual knowledge of integrated primary care. In contrast, attitudes (both negative and favourable) did not significantly change following the training. Participants indicated high satisfaction and acceptability ratings, and feasibility was attained as over 75% of the sample completed the training in the estimated 60-minutes. The results of the present study may help address the gaps in psychology graduate student training by describing and validating a curriculum specific to integrated primary care that can be efficiently integrated to psychology graduate student coursework.

Blowing Smoke: Why the Current Government Incentive Regime Makes EVs and PHEVs a Distant Prospect—and How to Fix It
Creators: name: Cohen, Clint
Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: An entire generation has greeted the arrival of plug-in hybrid-electric vehicles (“PHEVs”) with eager anticipation. However, the rise of a trend does not necessarily imply that spending habits will change—much less in a permanent way. The ambiguous prospects for popular PHEV and electric vehicle (“EV”) adoption demands discussion of what may keep them out of driveways, and how to overcome those barriers. This Note seeks to analyze how, through proper government incentive programs, EVs and PHEVs might become one mechanism for reducing the United States’ carbon emissions from transportation. Part I will set the backdrop for this analysis by discussing the history of EVs and PHEVs, and the government incentive programs already in place. Part II will cover the issues impeding popular adoption of EVs and PHEVs by consumers. Finally, Part III will propose a “model” government incentive program to overcome these issues. This program can be broken into five parts: educating consumers about EVs and PHEVs, switching the current tax credit scheme to an upfront rebate, reformulating the gas guzzler tax to make it more stringent, focusing on increasing fleet adoption of PHEVs, and establishing electrification “deployment communities” for EVs.

description: Recent lung cancer research has led to advancements in molecular immunology, resulting in development of small molecule inhibitors, or immune checkpoint inhibitors, that propagate an anti-tumor T cell response. Despite increased overall and progression-free survival with reduced adverse effects compared to traditional chemotherapy, treating advanced stage lung adenocarcinoma patients remains non-curative, and evidence of non-responders or tumor recurrence to immune checkpoint inhibitor therapy is growing. Also, compared to traditional chemotherapy, there is a lower percentage of patients who respond to small molecule inhibitors. In this analysis of proteomic and genomic data from The Cancer Proteome Atlas and Global Data Commons cancer databases, as well as clinical outcomes data from Phase II POPLAR and Phase III OAK clinical trials, we discuss possible prognostic and predictive factors of immunotherapy in the treatment of advanced non-small-cell lung carcinoma.

description: Using first principles many-body theory methods (GW+BSE) we demonstrate that optical properties of graphane are dominated by localized charge-transfer excitations governed by enhanced electron correlations in a two-dimensional dielectric medium. Strong electron-hole interaction leads to the appearance of small radius bound excitons with spatially separated electron and hole, which are localized out-of-plane and in-plane, respectively. The presence of such bound excitons opens the path on excitonic Bose-Einstein condensate in graphane that can be observed experimentally.

Beam-plasma system and its X-ray directivity

description: An evolution of the electron distribution function in the beam-plasma system with the return current is computed numerically for different parameters. The X-ray bremsstrahlung corresponding to such an electron distribution is calculated and the directivity of the X-ray emission is studied. For computations of the electron distribution functions we used a 3-D particle-in-cell electromagnetic code. The directivity of the X-ray emission was calculated using the angle-dependent electron-ion bremsstrahlung cross-section. It was found that the resulting electron distribution function depends on the magnetic field assumed along the electron beam propagation direction. For small magnetic fields the electron distribution function becomes broad in the direction perpendicular to the beam propagation due to the Weibel instability and the return current is formed by the electrons in a broad and shifted bulk of the distribution. On the other hand, for stronger magnetic fields the distribution is more extended in the beam-propagation direction and the return current is formed by the electrons in the extended distribution tail. In all cases, the anisotropy of the electron distribution decreases rapidly due to fast collisionless processes. However, the magnetic field reduces this anisotropy decrease. The X-ray directivity shows the same trend and it is always closer to the isotropic case than that in a simple beaming model.

description: Recent years have shown many advances in our knowledge of the collisional evolution of protoplanetary dust. Based on a variety of dust-collision experiments in the laboratory, our view of the growth of dust aggregates in protoplanetary disks is now supported by a deeper understanding of the physics involved in the interaction between dust agglomerates. However, the parameter space, which determines the collisional outcome, is huge and sometimes inaccessible to laboratory experiments. Very large or fluffy dust aggregates and extremely low collision velocities are beyond the boundary of today's laboratories. It is therefore desirable to augment our empirical knowledge of dust-collision physics with a numerical method to treat arbitrary aggregate sizes, porosities and collision velocities. In this article, we implement experimentally-determined material parameters of highly porous dust aggregates into a Smooth Particle Hydrodynamics (SPH) code, in particular an omnidirectional compressive-strength and a tensile-strength relation. We also give a prescription of calibrating the SPH code with compression and low-velocity impact experiments. In the process of calibration, we developed a dynamic compressive-strength relation and estimated a relation for the shear strength. Finally, we defined and performed a series of benchmark tests and found the agreement between experimental results and numerical simulations to be very satisfactory. SPH codes have been used in the past to study collisions at rather high velocities. At the end of this work, we show examples of future applications in the low-velocity regime of collisional evolution.

Stifling the Wind: California Environmental Quality Act and Local Permitting
Creators: name: Troxler, Brian
Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: At the turn of the millennium, California led the nation in installed wind energy capacity. California had over 1600 megawatts (“MW”) of capacity, representing a majority of the nation’s 2472 MW. The second most developed state had only had seventeen percent of California’s capacity. However, since 2000, wind capacity in the United States has increased twentyfold to almost 50,000 MW, while capacity in California has less than tripled. Although many factors contribute to differing rates wind energy development across the United States, California’s decentralized siting and arduous environmental evaluation requirements should bare blame. Though California still maintains the third most installed wind energy capacity, despite ranking nineteenth in terms of total wind generating potential, it still has 34,000 MW of uptapped on-shore economic wind potential. In-state wind resources have the potential to meet 39.4% of the State’s current energy needs but currently only provide 3.3%. Focusing on California’s relative wind potential understates California’s ability to develop practically viable wind resources in the near future. Moreover, attributing California’s repressed growth solely to its relative amount of wind resources oversimplifies the issue and ignores the possibility that California’s regulatory regime and its implementation may be less accommodating to wind energy development than regimes in other states. California allows local governments to site commercial wind projects, delegating this technical and complicated task to planning committees that are often not specialized. The California Environmental Quality Act (“CEQA”) further complicates this process. Under CEQA, the local government must analyze the environmental impacts of proposed projects and consider those impacts in deciding whether to issue a permit. The combination of decentralized siting and stringent environmental evaluation shrouds the cost, outcome, and timeline of the permitting process in uncertainty, chilling investment in new capacity. However, environmental evaluation procedures should clearly not be discarded. Wind projects may damage wildlife habitats or kill birds and bats, especially when poorly sited. Towering wind turbines dominate rural landscapes, sometimes disrupting aesthetically important sites or causing noise pollution. Despite these potential impacts, wind energy benefits the environment substantially by reducing pollutant emissions and water consumption. Thus, the challenge is to site wind projects efficiently in less environmentally sensitive areas. The California state government should take a significant step towards this goal by exercising its authority to site wind energy projects and by conducting environmental review of those projects in a uniform, timely, and predictable manner.

These criteria are more sensitive than those involving only second-order moments, and are equivalent to well-known variance product tests in the case of Gaussian states. Furthermore, they involve only a pair of quadrature measurements, and will thus should prove extremely useful the experimental identification of entanglement.

Local strong parity violation and new possibilities in experimental study of non-perturbative QCD

Year: 2010
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Quark interaction with topologically non-trivial gluonic fields, instantons and sphalerons, violates ¶and \CP symmetry. In the strong magnetic field of a non-central nuclear collision such interactions lead to the charge separation along the magnetic field, the so called chiral magnetic effect, which manifests local parity violations. An experimental observation of the chiral magnetic effect would be a direct proof for the existence of such physics. Recent STAR results on charge and the reaction plane dependent correlations are consistent with theoretical expectations for the chiral magnetic effect. IIn this paper I discuss different approaches to experimental study of the local parity violation, and propose future measurements which can clarify the picture. In particular I propose to use central body-body U+U collisions to disentangle correlations due to chiral magnetic effect from possible background correlations due to elliptic flow. Further more quantitative studies can be performed with collision of isobaric beams.

description: We consider spherically symmetric solutions within the context of brane-world theory without mirror symmetry or any form of junction conditions. For a constant curvature bulk, we obtain the modified Tolman-Oppenheimer-Volkoff (TOV) interior solutions in two cases where one is matched to a schwarzschild-de Sitter exterior while the other is consistent with an exterior solution whose structure can be used to explain the galaxy rotation curves without postulating dark matter. We also find the upper bound to the mass of a static brane-world star and show that the influence of the bulk effects on the interior solutions is small. Finally, we investigate the gravitational collapse on the brane and show that the exterior of a collapsing star can be static in this scenario.

description: The presented work aimed to investigate pre-recorded tutorials' impact on online fatigue and students' performance. An anonymous survey was conducted to explore students' note-taking habits, perceptions, and preferences for live or pre-recorded tutorials. Interestingly, results suggest an even split between preferences for live and pre-recorded tutorials and a diverse range of preferences and potential coping strategies for remote learning. Both formats offer benefits. By incorporating the valued aspects of each format, such as real-time question periods in live sessions and the ability to replay content in pre-recorded tutorials, educators can create a more engaging and effective learning environment. Furthermore, understanding students' note-taking habits and perceptions can help educators support students in developing strategies to maintain attention and engagement during remote learning.

description: Under dimensional reduction, a system in D spacetime dimensions will not necessarily yield its D-1-dimensional analog version. Among other things, this result will depend on the boundary conditions and the dimension D of the system. We investigate this question for scalar and abelian gauge fields under boundary conditions that obey the symmetries of the action. We apply our findings to the Casimir piston, an ideal system for detecting boundary effects. Our investigation is not limited to extra dimensions and we show that the original piston scenario proposed in 2004, a toy model involving a scalar field in 3D (2+1)dimensions, can be obtained via dimensional reduction from a more realistic 4D electromagnetic (EM) system. We show that for perfect conductor conditions, a D-dimensional EM field reduces to a D-1 scalar field and not its lower-dimensional version. For Dirichlet boundary conditions, no theory is recovered under dimensional reduction and the Casimir pressure goes to zero in any dimension. This "zero Dirichlet" result is useful for understanding the EM case. We then identify two special systems where the lower-dimensional version is recovered in any dimension: systems with perfect magnetic conductor (PMC) and Neumann boundary conditions. We show that these two boundary conditions can be obtained from a variational procedure in which the action vanishes outside the bounded region. The fields are free to vary on the surface and have zero modes which survive after dimensional reduction.

NEPA’s broadest goal—that the government “foster and promote the general welfare, to create and maintain conditions under which man and nature can exist in productive harmony, and fulfill the social, economic, and other requirements of present and future generations”—is not, by contrast, law to be enforced. In short, NEPA’s ultimate goal of making American society more sustainable has been marginalized even as its chief procedural tool—the Environmental Impact Statement (“EIS”)—has become ubiquitous. NEPA section 102(2)(C) clearly mandates in a modally unmistakable way that “all agencies of the Federal government,” when taking any “major Federal action[] significantly affecting the quality of the human environment,” prepare an EIS, specifying some of the contents thereof. Nothing in the statute even comes close to doing so for its more substantive objectives. For all the judicial pronouncements that NEPA is an “essentially procedural” statute, the question remains whether any such pronouncements bind the executive branch, preventing it from putting NEPA’s more substantive aspects into effect. The Supreme Court has held that “[b]efore a judicial construction of a statute . . . may trump an agency’s, the court must hold that the statute unambiguously requires the court’s construction.” Such holdings need not be expressed in these exact terms, but the Court’s formula clearly empowers the executive. Indeed, a judicial construction only binds as to the “precise question at issue.” Are there any such precedents in NEPA’s past? If so, how should they inform the President, whose duty and power it is to “take care” that the “Laws be faithfully executed”?

description: The ZZ Ceti star KUV 02464+3239 was observed over a whole season at the mountain station of Konkoly Observatory. A rigorous frequency analysis revealed 6 certain periods between 619 and 1250 seconds, with no shorter period modes present. We use the observed periods, published effective temperature and surface gravity, along with the model grid code of Bischoff-Kim, Montgomery and Winget (2008) to perform a seismological analysis. We find acceptable model fits with masses between 0.60 and 0.70 M_Sun. The hydrogen layer mass of the acceptable models are almost always between 10^-4 and 10^-6 M_*. In addition to our seismological results, we also show our analysis of individual light curve segments. Considering the non-sinusoidal shape of the light curve and the Fourier spectra of segments showing large amplitude variations, the importance of non-linear effects in the pulsation is clearly seen.

Picking Winners and Losers: A Structural Examination of Tax Subsidies to the Energy Industry
Creators: name: Roberts, Tracey M.
Publisher: name: Columbia Journal of Environmental Law
Year: 2019

description: In debates over whether government should continue to subsidize renewable energy, politicians have repeatedly warned that government should not be “picking winners and losers.” This way of framing the debate undermines sensible policy analysis in two ways. First, it obscures the long history of federal support for fossil fuels; the United States has been picking winners and losers for over 100 years. Second, it fails to articulate what it means to “pick winners and losers,” to explain why doing so is less efficient than pursuing other economic policies, and to inquire why this suboptimal choice has been made. This article addresses these failings by examining two sets of tax subsidies to the energy industry, one for fossil fuels and the other for renewables. Part II of this article describes economic situations that would justify government intervention in the energy markets and explains why Congress has chosen to “pick winners and losers.” Part III examines the history of subsidies to both fossil fuels and renewable energy resources in light of those rationales and describes the divergent market trajectories of the two sets of subsidies. Part IV evaluates the subsidies on a qualitative basis, developing the thesis that the disparate market impacts derive from the differences in the way the subsidies are structured. This Part examines the subsidies’ relative risks, information costs, and transaction costs, liquidity and marketability. Part V examines the political economy associated with the subsidies, including their budgetary history, the first mover advantage available to fossil fuels, and the political advantages and administrative bias favoring subsidies that are shared with other sectors. It argues that certain structures have provided stability and certainty for fossil fuels and expanded their market share and that other structures have exposed renewables to legislative volatility and failure. Part VI discusses recent proposals for reform and Part VII concludes the article.

description: BaIrO3 is a novel insulator with coexistent weak ferromagnetism, charge and spin density wave. Dilute RE doping for Ba induces a metallic state, whereas application of modest pressure readily restores an insulating state characterized by a three-order-of-magnitude increase of resistivity. Since pressure generally increases orbital overlap and broadens energy bands, a pressure-induced insulating state is not commonplace. The profoundly dissimilar responses of the ground state to light doping and low hydrostatic pressures signal an unusual, delicate interplay between structural and electronic degrees of freedom in BaIrO3.
Development of the National Environmental Sustainability and Technology Tool (NESTT) : a sustainability measurement and management platform for Canadian egg farmers
Creators: name: Arulnathan, Vivek

description: The global agri-food system is necessarily central to contemporary sustainability discourse due to its significant contribution to major environmental issues and livestock-based food production is particularly impactful and considered among the top three contributors to most serious global environmental issues. As a result, there is growing consumer and regulatory demand for better sustainability measurement and management capabilities in the agri-food sector. Farm-level sustainability decision support tools characterized by their ease of access, simplified sustainability assessment models, and emphasis on effective communication and aesthetic appeal are particularly salient in this context. The dissertation research reported herein culminated in the development of a tool with such characteristics – the National Environmental Sustainability and Technology Tool (NESTT) – which was developed for the Canadian egg industry. NESTT can help Canadian egg farmers measure their farm’s environmental impacts, evaluate the mitigation potential of sustainability technologies and strategies, benchmark their performance against industry standards, and track their performance over time. The sustainability assessment framework in NESTT was based on Life Cycle Assessment (LCA). A new allocation method based on metabolic energy partitioning in hens was developed to address multifunctionality (a major methodological consideration in LCAs) in NESTT in way that is compliant with the natural science basis and requirements of the ISO 14044 standard for LCA. For measuring impacts, a modular approach based on multi-level aggregation of life cycle impacts across six modules – pullets, feed, energy inputs, water, manure management, and transportation – was implemented. To ensure that NESTT meets the requirements of farmers, a participatory design approach involving surveys and interviews of egg farmers was employed. Improvements related to user-centeredness, aesthetic appeal, and accessibility were achieved and long-term strategic options such as integrating economic assessments and adding more customized decision support features were identified in consultation with farmers. In support of these long-term goals, a preliminary economic assessment framework was also developed and integration of Multi Criteria Decision Analysis (MCDA) methods with LCA for customized decision support was explored. Overall, NESTT provides a unique, first of its kind tool to provide farmers with multi-criteria, LCA-based assessment capabilities in both Canada and the egg sector globally.
The Threat Divider: Expanding the Role of the Military in Climate Change Adaptation

description: It is all but undeniable that climate change creates drastic national security concerns for the United States, despite the assertions of certain contrary political forces. While the United States legislature and judiciary can and should play a direct role in addressing these risks by abrogating climate risk, the executive branch and its agencies, in comparison, possess tremendous opportunities and abilities to do so. Specifically, the armed forces under the DoD face unique challenges, but also possess unique advantages, in the realm of climate change adaptation. Certainly the military divisions under the executive play a paramount role in hemming national security risks; due to its developing expertise, the possibility of the military’s enormous influence in the realm of climate change adaptation should be recognized and embraced. This Note argues that the military’s role in climate change adaptation—specifically in regards to national security threats domestically and abroad—should be embraced and expanded as adaptation efforts become increasingly necessary.

Looking in the Side-View Mirror: Assessing the Current and Future State of the Solar Energy Industry as it Reaches the Mainstream
Creators: name: Palumbo, Brian
Publisher: name: Columbia Journal of Environmental Law

description: The popularity of solar energy has risen as its cost has rapidly decreased since 2005. A Deutsche Bank projection claims that the cost of solar energy will reach grid parity by 2016, and an International Energy Agency report asserts that by 2050, solar energy could be a viable source of electricity worldwide. On its face, these projections depict a bright future for solar energy and society. Yet solar energy’s presence as an alternative form of energy might be more vulnerable than forecasts depict. With the upcoming expiration of valued government incentives and pushback from energy competitors, solar energy will not run untouched to the end-zone. In other words, solar energy approaches a critical juncture where its deficiencies might come to the forefront. To view these vulnerabilities, a qualitative investigation of solar energy is required. Solar energy is growing at a remarkable rate, yet there are factors intrinsic to the industry that have not yet influenced its growth into adolescence. One must analyze current solar energy issues along with the industry’s unique characteristics to properly assess the situation from a complete perspective and to observe its possible exposure to an array of complications. Lawmakers, from all levels of government, must then acknowledge and act on these findings to prudently regulate the solar industry.

The religion of love (Mazhab-e 'Ishq) in the time of colonialism : contradictory articulations of vernacular literary style in eighteenth century India
Creators: name: Lone, Mahnoor Ishtiaq
Publisher: name: University of British Columbia
Year: 2023

description: Mazhab-e ‘Ishq (The Religion/School of Love, 1803) was a prose text written at the British colonial College of Fort William—an institution which engendered lasting literary and linguistic transformation in India/Hindustan. This thesis engages with this text and the various social, political, and literary contexts informing its production to create a deeper understanding of pre-colonial Persianate literary culture as well as the ways in which literary culture was transformed in eighteenth century Hindustan. It begins by analyzing the changing attitudes of the East India Company towards Indian languages over the course of the eighteenth century that preceded the foundation of Fort William College. Chapter One argues that the Company’s shift towards patronizing and standardizing the vernacular it labelled as Hindustani, and later as Urdu, was shaped by concurrent changes in its administrative rhetoric and legal and economic policies. The following chapters engage with the text of Mazhab-e ‘Ishq and trace the various affiliations of the text and its writer Nihal Chand Lahori. Chapter Two describes the stylistic ideals of Fort William College’s project as well as the stylistic ideas which shaped the co-terminous production of vernacular poetry in Delhi—away from the colonial ambit. I argue that Lahori’s description of his text as a work in hindī rēkhtā indicates that these latter ideals also influenced the poetics, aesthetics, and intent of his work. The third chapter close-reads the story of Mazhab-e ‘Ishq and explicates upon its connections to the pre-colonial genre of the premākhyān while also exploring how the style and aesthetics used to tell this story in Mazhab-e ‘Ishq were effected by its appropriation into the European category of literature. Through this engagement I attempt to describe how the colonial alteration of stylistic ideals and side-lining of aesthetic finesse influenced the ways in which Persianate stories could be read, understood, and experienced. It argues for reading texts such as Mazhab-e ‘Ishq, which are simultaneously shaped by earlier Persianate traditions and colonial literary projects, in a critical way that allows us to know more about pre-colonial Persianate literary forms as well as their transformation through colonial institutions.
