description: A life cycle assessment of the Doug Mitchell Thunderbird Sports Center (DMTSC) on the University of British Columbia campus was conducted to determine the environmental impacts related to its manufacturing and construction. Eight impact categories were considered including global warming potential, weighted resource use and fossil fuel consumption. This study did not include the impacts associated with operating energy, maintenance or end-of-life. This is one study in a series of studies on three sports facilities, the others being the Richmond Olympic Oval and the old Thunderbird Arena on the same site as the DMTSC. DMTSC is a sports arena with two skating rinks and up to 7500 seats. A third skating rink remains from the old Thunderbird Arena and is attached to the West side of the building. The DMTSC is currently home to the UBC Thunderbirds Ice Hockey Team and played a large role in the 2010 Winter Olympic Games as a venue for Ice Hockey and Sledge Hockey. DMTSC is a primarily concrete building. Several of the most common materials include PVC membranes, concrete blocks, foam polyisocyanurate, 30MPa concrete and steel rebar. On-Screen Takeoff Pro was used to quantify all the building materials and the Athena Impact Estimator was used to calculate the associated impacts. Assumptions were required in several stages, and these are documented and accounted for in this report. Over 48 million kg of CO2 equivalent were created in the manufacture and construction of the DMTSC and over 23 million kg of weighted resources.

Pandora's box lid: geometry near the apparent horizon

subject: FOS: Physical sciences

description: Trapped regions bounded by horizons are the defining features of black holes. However, formation of a singularity-free apparent horizon in finite time of a distant observer is consistent only with special states of geometry and matter in its vicinity. In spherical symmetry such horizons exist only in two classes of solutions of the Einstein equations. Both violate the null energy condition (NEC) and allow for expanding and contracting trapped regions. However, an expanding trapped region leads to a firewall. The weighted time average of the energy density for an observer crossing this firewall is negative and exceeds the maximal NEC violation that quantum fields can produce. As a result, either black holes only can evaporate or the semiclassical physics breaks down already at the horizons. Geometry of a contracting trapped region approaches the ingoing Vaidya metric with decreasing mass. Only one class of solutions allows for a test particle to cross the apparent horizon, and for a thin shell to collapse into a black hole. These results significantly constrain the regular black hole models. Models with regular matter properties at the horizon can be realized only if significant departures from the semiclassical physics occur already at the horizon scale. The Hayward-Frolov model may describe only evaporation, but not formation of a regular black hole.

High Energy Photon-Photon Collisions at a Linear Collider

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: High intensity back-scattered laser beams will allow the efficient conversion of a substantial fraction of the incident lepton energy into high energy photons, thus significantly extending the physics capabilities of an electron-electron or electron-positron linear collider. The annihilation of two photons produces C=+ final states in virtually all angular momentum states. The annihilation of polarized photons into the Higgs boson determines its fundamental two-photon coupling as well as determining its parity. Other novel two-photon processes include the two-photon production of charged lepton pairs, vector boson pairs, as well as supersymmetric squark and slepton pairs and Higgstrahlung. The one-loop box diagram leads to the production of pairs of neutral particles. High energy photon-photon collisions can also provide a remarkably background-free laboratory for studying possibly anomalous $W W$ collisions and annihilation. In the case of QCD, each photon can materialize as a quark anti-quark pair which interact via multiple gluon exchange. The diffractive channels in photon-photon collisions allow a novel look at the QCD pomeron and odderon. Odderon exchange can be identified by looking at the heavy quark asymmetry. In the case of electron-photon collisions, one can measure the photon structure functions and its various components. Exclusive hadron production processes in photon-photon collisions test QCD at the amplitude level and measure the hadron distribution amplitudes which control exclusive semi-leptonic and two-body hadronic B-decays.

An investigation into the use of linoleum and hemp in the new SUB : a triple bottom line assessment

description: As the campaign for sustainable housing increases globally and across UBC, the demand for rapidly renewable resources rises. There is a swift increase in the number of new buildings, including the new Student Union Building’s Platinum+ goal, that are aiming to achieve various Canada Green Building Council’s LEED certifications(Canadian Green Building Council). The purpose of this study is to conduct a triple-­‐bottom line analysis on linoleum and hemp, with specific focus on hempcrete, to determine whether these constituents are viable rapidly renewable building materials suitable for use in the new SUB. This paper includes extensive journal research, primary data collection in the forms of surveys and interviews, and secondary data compilation such as government videos, blogs, and various other sources. From an environmental perspective, both linoleum and hemp can be harvested with relative ease, and are greenhouse gas emissions neutral and negative, respectively. There are minimal usage of pesticides and toxic chemicals during the production and maintenance phase. Each material is biodegradable so waste sent to landfills does not negatively impact the environment. Moreover, from an economic standpoint, linoleum is one of the cheapest rapidly renewable materials available, while hemp despite its initial high production price is highly subsidized, thereby driving the domestic prices down. The low operation and maintenance cost of each material makes them great economic solutions for extended lifetimes. Lastly, the social impacts of choosing linoleum and hempcrete are notable. Not only do linoleum and hemp encourage the growth of local producers, leading to a rise in local employment, but they also create a comfortable and aesthetically pleasing environment for the occupants. Linoleum and hemp are both very durable and therefore, resistant to demanding conditions over a long time period. This radically reduces the required maintenance work, and lends these materials to be very effective in high traffic locations. Based on the findings from the triple-­‐bottom line analysis, it is determined that linoleum and hemp are both exceptional materials that exceed the LEED’s rapidly renewable material requirement. However, because neither material can be obtained locally within the 500 mile radius, the local criteria cannot be met.

description: The recent emerging fields in data processing and manipulation has facilitated the need for synthetic data generation. This is also valid for mobility encounter dataset generation. Synthetic data generation might be useful to run research-based simulations and also create mobility encounter models. Our approach in this paper is to generate a larger dataset by using a given dataset which includes the clusters of people. Based on the cluster information, we created a framework. Using this framework, we can generate a similar dataset that is statistically similar to the input dataset. We have compared the statistical results of our approach with the real dataset and an encounter mobility model generation technique in the literature. The results showed that the created datasets have similar statistical structure with the given dataset.

description: Although automated driving systems have been used frequently, they are still unpopular in society. To increase the popularity of automated vehicles (AVs), assisting pedestrians to accurately understand the driving intentions and improving their perception of safety when interacting with AVs are considered effective. Therefore, the AV should send information about its driving intention to pedestrians when they interact with each other. However, the following questions should be answered regarding how the AV sends the information to them: 1) What timing for an AV to make pedestrians understand its driving intentions after being noticed by them? 2) What timing for an AV to make pedestrians feel safe after being noticed by them? Thirteen participants were invited to interact with a manually driven vehicle and an AV in an experiment. The participants' gaze information and a subjective evaluation of their understanding of the driving intention as well as their perception of safety were collected. By analyzing the participants' gaze duration on the vehicle with their subjective evaluations, we found that the AV should enable the pedestrian to accurately understand its driving intention within 0.5~6.5 [s] and make the pedestrian feel safe within 0.5~8.0 [s] while the pedestrian is gazing at it.

We show that the stirring rate can control the macroscopic behavior of the system producing collective oscillations (synchronization) or complete quenching of the oscillations (oscillator death). We interpret the homogenization rate due to mixing as a measure of global coupling and compare the phase diagrams of stirred oscillatory media and of populations of globally coupled oscillators.

U.S. farm policy as fraught populism : Tracing the scalar tensions of nationalist agricultural governance
Creators: name: Graddy-Lovelace, T. Garrett
Publisher: name: American University
Year: 2023

description: The scalar tensions of nationalism manifest acutely in agriculture—particularly in the contemporary United States. This is paradoxical because farm policy calls for and enacts nativist governance that undermines the conditions of farming: from labor to water, topsoil, and pollinators, to export markets. At the heart of these scalar contradictions is the fraught, shifting terrain of agrarian populism. The intertwined origin of the U.S. Farm Bill, the American Farm Bureau Federation, and Cooperative Agricultural Extension shows how early twentieth-century fraught agrarian populism drove farm policy but how it also carried a pivotal consensus of recognition about the ecological and economic dangers of overproduction. Drawing on archival research at the U.S. Department of Agriculture's (USDA) National Agricultural Library Special Collections, discourse and policy analysis of U.S. Farm Bills, and qualitative research with farmer organizations, this article traces how racialized xenophobia accentuates the hypocrisy of U.S. agriculture’s extreme dependency on migrant labor, as heightened borders also reveal their ecological farce in the face of intrinsically transnational climate change, soil erosion, and water constraints. The America First trade agenda decries imports while sidelining the crisis of commodity crop glut and the spatial fix of subsidizing exports as surplus disposal. Yet, even amidst the scalar contradictions of nativist agricultural governance and the fraught farm populism driving it, there existed a kernel of agrarian populism grounded in a collective honest recognition of the ecological, economic, rural, and social crises of overproduction—and that organized against it. This kernel catalyzed the origin of both the Farm Bill and the Farm Bureau but has been subsumed in and through both since.

description: The fluctuations of the magnetic order parameter, or longitudinal spin excitations, are investigated theoretically in the ferromagnetic Fe and Ni as well as in the antiferromagnetic phase of the pnictide superconductor FeSe. The charge and spin dynamics of these systems is described by evaluating the generalized charge and spin density response function calculated from first-principles linear response time dependent density functional theory within adiabatic local spin density approximation. We observe that the formally non-interacting Kohn-Sham system features strong coupling between the magnetization and charge dynamics in the longitudinal channel and that the coupling is effectively removed upon the inclusion of the Coulomb interaction in the charge channel and the resulting appearance of plasmons. The longitudinal spin fluctuations acquire a collective character without the emergence of the Goldstone boson, similar to the case of paramagnon excitations in non-magnetic metals like Pd. In ferromagnetic Fe and Ni the longitudinal spin dynamics is governed by interactions between low-energy intraband electron-hole pairs while in quasi two dimensional antiferromagnet FeSe it is dominated by the interband transitions with energies of the order of exchange splitting. In the later material, the collective longitudinal magnetization fluctuations feature well defined energies and long life times for small momenta and appear below the particle-hole continuum. The modes become strongly Landau-damped for growing wave-vectors. We relate our theoretical findings to existing experimental spin-polarized electron energy loss spectroscopy results. In bulk bcc Fe, the longitudinal magnetic modes appear above the typical energies of transverse spin-waves, have energies comparable with the Stoner spin-flip excitation continuum, and are order of magnitude less energetic than the charge dynamics.

description: Inclusive charged-particle measurements probe the low-energy region of the non-perturbative quantum chromodynamics. The ATLAS collaboration has recently measured the charged-particle multiplicity and its dependence on transverse momentum and pseudorapidity in special data sets with low LHC beam currents, recorded at centre-of-mass energies of 8 TeV and 13 TeV. The measurements at 8 TeV cover a wide spectrum using charged-particle selections with minimum transverse momentum of both 100 MeV and 500 MeV and in various phase space regions of low and high charged-particle multiplicities, some of which are studied for the first time by ATLAS. The measurements at 13 TeV also present detailed studies with a minimum transverse momentum of both 100 MeV and 500 MeV. The measurements are compared with predictions of various tuned Monte Carlo generators and are found to provide strong constraints on these. None of the Monte Carlo generators with their respective tunes are able to reproduce all the features of the data.

description: We test the analytical formula for the enhancement of the nuclear magnetic resonance rate $T_1^{-1}$ by the critical spin fluctuations, over the simple power-law dependence predicted for a purely one-dimensional spin system, recently derived in the random phase approximation [M. Dupont et al., Phys. Rev. B 98, 094403 (2018)]. This prediction is experimentally confirmed by excellent fits to the published temperature dependence of $T_1^{-1}$ data in the two representative spin compounds, (C$_7$H$_{10}$N)$_2$CuBr$_4$ (DIMPY) and BaCo$_2$V$_2$O$_8$, providing at the same time a direct and convenient experimental determination of the Tomonaga-Luttinger-liquid parameter $K$, very well in agreement with theoretical predictions.

description: We study the chaotic dynamics of graphene structures, considering both a periodic, defect free, graphene sheet and graphene nanoribbons (GNRs) of various widths. By numerically calculating the maximum Lyapunov exponent, we quantify the chaoticity for a spectrum of energies in both systems. We find that for all cases, the chaotic strength increases with the energy density, and that the onset of chaos in graphene is slow, becoming evident after more than $10^4$ natural oscillations of the system. For the GNRs, we also investigate the impact of the width and chirality (armchair or zigzag edges) on their chaotic behavior. Our results suggest that due to the free edges the chaoticity of GNRs is stronger than the periodic graphene sheet, and decreases by increasing width, tending asymptotically to the bulk value. In addition, the chaotic strength of armchair GNRs is higher than a zigzag ribbon of the same width. Further, we show that the composition of ${}^{12}C$ and ${}^{13}C$ carbon isotopes in graphene has a minor impact on its chaotic strength.

description: We discuss diphoton semi(exclusive) production in ultraperipheral P bP b collisions at energy of √ sNN = 5.5 TeV (LHC). The nuclear calculations are based on equivalent photon approximation in the impact parameter space. The cross sections for elementary γγ → γγ subprocess are calculated including three different mechanisms: box diagrams with leptons and quarks in the loops, a VDM-Regge contribution with virtual intermediate hadronic excitations of the photons and the two-gluon exchange contribution (formally three-loops) to elastic photon-photon scattering in the high-energy approximation. We got relatively high cross sections in P bP b collisions (306 nb). This opens a possibility to study the γγ → γγ (quasi)elastic scattering at the LHC. We find that the cross section for elastic γγ scattering could be measured in the lead-lead collisions for the diphoton invariant mass up to Wγγ ≈ 15 − 20 GeV. We identify region(s) of phase space where the twogluon exchange contribution becomes important ingredient compared to box and nonperturbative VDM-Regge mechanisms. We perform a similar analysis for the pp → ppγγ reaction at energy of √ sNN = 7 and 100 TeV.

description: A gazdasági életben sok esetben találkozunk olyan döntési helyzetekkel, amikor a döntéshozatal nagy felelősséggel jár, mert a későbbi versenyképesség függhet tőle. Ezen szituációk megoldására tudatosan felépített döntési modellek használata válhat szükségessé, hogy a körülményeknek megfelelő optimális döntést hozhassuk meg. A különböző döntési modellek között a Data Envelopment Analysis (DEA) igen sajátos eljárás, amely alkalmas a döntéshozatal szempontjából hasznos információk feltárására, olyan gazdálkodó szervezeteknél, amelyek több döntéshozó egység integrált működését foglalják magukba. A DEA analízis számos területen alkalmazható a gyakorlatban, a szakirodalom alapján megállapítható, hogy világszerte alkalmazott, népszerű módszer a hatékonyság vizsgálatára, ezért választottuk mi is ezt a módszert egy magyarországi libatartó gazdaság hatékonysági vizsgálatához. A vizsgálat fő célja, hogy a nem megfelelően (nem hatékonyan) működő vállalkozásoknál (döntési egységeknél) választ kapjunk arra, hogy melyek azok a tényezők, amelyek a működés hatékonyságát negatív irányban befolyásolják. ----------------- In many cases we face determinative decision-making situations in our economy, where decision-making entails great responsibility for us, since later competitiveness may depend on them. To solve these situations, there is a necessity to use consciously deployed decision models making the most optimal decision according to the circumstances. Among the different decision models, the data envelopment analysis (DEA) is a very specific process that can be used to reveal information what is useful for decision making in economic organizations that involve the integrated operation of multiple decision-making units. The DEA analysis can be applied in many fields in practice, it is widely used in professional literatures, and it is a popular method for assessing efficiency, and we thought that we investigate a Hungarian goose farm regarding efficiency. The main objective of the study is to find out which factors influence the efficiency of the operation negatively in the case of inefficient production units.

description: Baxter permutations, plane bipolar orientations, and a specific family of walks in the non-negative quadrant are well-known to be related to each other through several bijections. We introduce a further new family of discrete objects, called coalescent-walk processes, that are fundamental for our results. We relate these new objects with the other previously mentioned families introducing some new bijections. We prove joint Benjamini--Schramm convergence (both in the annealed and quenched sense) for uniform objects in the four families. Furthermore, we explicitly construct a new fractal random measure of the unit square, called the coalescent Baxter permuton and we show that it is the scaling limit (in the permuton sense) of uniform Baxter permutations. To prove the latter result, we study the scaling limit of the associated random coalescent-walk processes. We show that they converge in law to a continuous random coalescent-walk process encoded by a perturbed version of the Tanaka stochastic differential equation. This result has connections (to be explored in future projects) with the results of Gwynne, Holden, Sun (2016) on scaling limits (in the Peanosphere topology) of plane bipolar triangulations. We further prove some results that relate the limiting objects of the four families to each other, both in the local and scaling limit case.

Gravity as Archimedes' thrust and a bifurcation in that theory

description: Euler's interpretation of Newton's gravity (NG) as Archimedes' thrust in a fluid ether is presented in some detail. Then a semi-heuristic mechanism for gravity, close to Euler's, is recalled and compared with the latter. None of these two "gravitational ethers" can obey classical mechanics. This is logical since the ether defines the very reference frame, in which mechanics is defined. This concept is used to build a scalar theory of gravity: NG corresponds to an incompressible ether, a compressible ether leads to gravitational waves. In the Lorentz-Poincaré version, special relativity is compatible with the ether, but, with the heterogeneous ether of gravity, it applies only locally. A correspondence between metrical effects of uniform motion and gravitation is assumed, yet in two possible versions (one is new). Dynamics is based on a (non-trivial) extension of Newton's second law. The observational status for the theory with the older version of the correspondence is summarized.

description: We have studied the charge-density-wave (CDW) state for the superconducting Lu$_5$Ir$_4$Si$_{10}$ and the antiferromagnetic Er$_5$Ir$_4$Si$_{10}$ as variables of temperature, magnetic field, and hydrostatic pressure. For Lu$_5$Ir$_4$Si$_{10}$, the application of pressure strongly suppresses the CDW phase but weakly enhances the superconducting phase. For Er$_5$Ir$_4$Si$_{10}$, the incommensurate CDW state is pressure independent and the commensurate CDW state strongly depends on the pressure, whereas the antiferromagnetic ordering is slightly depressed by applying pressure. In addition, Er$_5$Ir$_4$Si$_{10}$ shows negative magnetoresistance at low temperatures, compared with the positive magnetoresistance of Lu$_5$Ir$_4$Si$_{10}$.
