title: How 'smart' are smart cities?: The case of Sidewalk Labs, Toronto
Creators: name: Alexander, Don
Publisher: name: VIU Press
Year: 2021
Subjects: subject: City planning--Ontario--Toronto
subject: Smart cities

description: This article looks at the debate surrounding the smart city concept in theory and practice using the proposed Smart Labs development in Quayside, Toronto as a case study. My approach has been to familiarize myself with the details of the case and the controversy surrounding it through a literature review and through consulting individuals who were involved, as well through looking at the broader literature on smart cities. As a planning educator, I observe a tendency on the part of students to consider new technology in an uncritical fashion, and the goal here is to promote critical thinking not to dismiss smart cities outright.
Quantitative study of electronic whispering gallery modes in electrostatic-potential induced circular graphene junctions

description: Electronic Whispering Gallery Modes (EWGMs) have been recently observed in several circular graphene junctions, pn and pp0, created in scanning tunnelling microscope experiments. By computing the local density of states within the Dirac-Weyl formalism for massless fermions we demonstrate that the EWGMs may really be emerged in any type of the electrostatic potential induced circular graphene junctions, including uni-junctions (e.g. np- or pp0-junctions) as well as bipolar-junctions (e.g. pnp-heterojunctions). Surprisingly, quantitative analyses show that for all the EWGMs identified (regardless of junction types) the quality (Q) factors seem to be smaller than 100, very small compared to those in ordinary optical whispering gallery modes microresonators, while the corresponding mode radii may tunably be in nanometer-scale. Our theoretical results are in good agreement with existent experimental data, putting a question to the application potential of the EWGMs identified.

description: Early recordings of nervous conduction revealed a notable thermal signature associated with the electrical signal. The observed production and subsequent absorption of heat arise from physicochemical processes that occur at the cell membrane level during the conduction of the action potential. In particular, the reversible release of electrical energy stored as a difference of potential across the cell membrane appears as a simple yet consistent explanation for the heat production, as proposed in the "Condenser Theory." However, the Condenser Theory has not been analyzed beyond the analogy between the cell membrane and a parallel-plate capacitor, i.e. a condenser, which cannot account for the magnitude of the heat signature. In this work, we use a detailed electrostatic model of the cell membrane to revisit the Condenser Theory. We derive expressions for free energy and entropy changes associated with the depolarization of the membrane by the action potential, which give a direct measure of the heat produced and absorbed by neurons. We show how the density of surface charges on both sides of the membrane impacts the energy changes. Finally, considering a typical action potential, we show that if the membrane holds a bias of surface charges, such that the internal side of the membrane is 0.05 C m$^{-2}$ more negative than the external side, the size of the heat predicted by the model reaches the range of experimental values. Based on our study, we identify the change in electrical energy of the membrane as the primary mechanism of heat production and absorption by neurons during nervous conduction.

description: Software metrics such as coverage or mutation scores have been investigated for the automated quality assessment of test suites. While traditional tools rely on software metrics, the field of self-driving cars (SDCs) has primarily focused on simulation-based test case generation using quality metrics such as the out-of-bound (OOB) parameter to determine if a test case fails or passes. However, it remains unclear to what extent this quality metric aligns with the human perception of the safety and realism of SDCs. To address this (reality) gap, we conducted an empirical study involving 50 participants to investigate the factors that determine how humans perceive SDC test cases as safe, unsafe, realistic, or unrealistic. To this aim, we developed a framework leveraging virtual reality (VR) technologies, called SDC-Alabaster, to immerse the study participants into the virtual environment of SDC simulators. Our findings indicate that the human assessment of safety and realism of failing/passing test cases can vary based on different factors, such as the test’s complexity and the possibility of interacting with the SDC. Especially for the assessment of realism, the participants’ age leads to a different perception. This study highlights the need for more research on simulation testing quality metrics and the importance of human perception in evaluating SDCs.

description: We analyze junction conditions at a null or non-null hypersurface $Σ$ in a large class of scalar-tensor theories in arbitrary $n(\ge 3)$ dimensions. After showing that the metric and a scalar field must be continuous at $Σ$ as the first junction conditions, we derive the second junctions conditions from the Einstein equations and the equation of motion for the scalar field. Subsequently, we study $C^1$ regular matching conditions as well as vacuum conditions at $Σ$ both in the Jordan and Einstein frames. Our result suggests that the following configurations may be possible; (i) a vacuum thin-shell at null $Σ$ in the Einstein frame, (ii) a vacuum thin-shell at null and non-null $Σ$ in the Jordan frame, and (iii) a non-vacuum $C^1$ regular matching at null $Σ$ in the Jordan frame. Lastly, we clarify the relations between the conditions for $C^1$ regularity and also for vacuum $Σ$ in the Jordan and Einstein frames.

Effect of well-width on the electro-optical properties of a quantum well

description: We record photoreflectance from Ge/GeSi modulation doped quantum wells possessing $10^4$ V/cm perpendicular electric fields. Qualitatively very different spectra are obtained from samples of well-width 100 Åand 250 Å. Comparing the wavefunctions calculated from an $8 \times 8$ \textbf{k.p} theory, we find that while they remain confined in the narrower 100 ÅQW, the electric field causes them to tunnel into the forbidden gap in the 250 Å well. This implies that the samples should show a transition from the quantum confined Franz-Keldysh effect to the bulk-like Franz-Keldysh effect. Close to the band-edge where Franz-Keldysh effects are important, simulated photoreflectance spectra reproduce the essential features of the experiment, without any adjustable parameters.

The Physics of Gamma-Ray Bursts

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Gamma-Ray Bursts (GRBs), short and intense pulses of low energy gamma-rays, have fascinated astronomers and astrophysicists since their unexpected discovery in the late sixties. During the last decade, several space missions: BATSE (Burst and Transient Source Experiment) on Compton Gamma-Ray Observatory, BeppoSAX and now HETE II (High-Energy Transient Explorer), together with ground optical, infrared and radio observatories have revolutionized our understanding of GRBs showing that they are cosmological, that they are accompanied by long lasting afterglows and that they are associated with core collapse Supernovae. At the same time a theoretical understanding has emerged in the form of the fireball internal-external shocks model. According to this model GRBs are produced when the kinetic energy of an ultra-relativistic flow is dissipated in internal collisions. The afterglow arises when the flow is slowed down by shocks with the surrounding circum-burst matter. This model has numerous successful predictions like the prediction of the afterglow itself, the prediction of jet breaks in the afterglow light curve and of an optical flash that accompanies the GRBs themselves. In this review I focus on theoretical aspects and on physical processes believed to take place in GRBs.

subject: FOS: Physical sciences

description: In many unconventional superconductors, nematic quantum fluctuations are strongest where the critical temperature is highest, inviting the conjecture that nematicity plays an important role in the pairing mechanism. Recently, Ba$_{1-x}$Sr$_x$Ni$_2$As$_2$ has been identified as a tunable nematic system that provides an ideal testing ground for this proposition. We therefore propose several sharp empirical tests, supported by quantitative calculations in a simple model of Ba$_{1-x}$Sr$_x$Ni$_2$As$_2$. The most stringent predictions concern experiments under uniaxial strain, which has recently emerged as a powerful tuning parameter in the study of correlated materials. Since uniaxial strain so precisely targets nematic fluctuations, such experiments may provide compelling evidence for nematic-mediated pairing, analogous to the isotope effect in conventional superconductors.
General solution of the Jeans equations for triaxial galaxies with separable potentials

description: The Jeans equations relate the second-order velocity moments to the density and potential of a stellar system. For general three-dimensional stellar systems, there are three equations and six independent moments. By assuming that the potential is triaxial and of separable Staeckel form, the mixed moments vanish in confocal ellipsoidal coordinates. Consequently, the three Jeans equations and three remaining non-vanishing moments form a closed system of three highly-symmetric coupled first-order partial differential equations in three variables. These equations were first derived by Lynden-Bell, over 40 years ago, but have resisted solution by standard methods. We present the general solution here. We consider the two-dimensional limiting cases first. We solve their Jeans equations by a new method which superposes singular solutions. The singular solutions, which are new, are standard Riemann-Green functions. The two-dimensional solutions are applied to non-axisymmetric discs, oblate and prolate spheroids, and also to the scale-free triaxial limit. We then extend the method of singular solutions to the triaxial case, and obtain a full solution. The general solution can be expressed in terms of complete (hyper)elliptic integrals which can be evaluated in a straightforward way, and provides the full set of second moments which can support a triaxial density distribution in a separable triaxial potential.

Twisted Kitaev Bilayers and the Moiré Ising Model

Publisher: name: arXiv
Year: 2019
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: In recent years, there have been numerous examples of twisted bilayer systems that host remarkable physical properties that are not found in their untwisted counterparts. Motivated by this, we study the properties of twisted bilayers of the Kitaev honeycomb model in the Abelian spin liquid phase. We show that for strong, short-ranged, interlayer interactions, a super-lattice of non-Abelian defects forms in the twisted bilayer system. These non-Abelian defects are wormhole-like genons that allow anyons from one layer to tunnel to the other layer. We find that when a magnetic field is applied to the system, the low energy dynamics of the twisted bilayer system can be mapped onto four quantum Ising models arising from the degrees of freedom localized on the genon defects. At small twist angles, the Ising models are in a trivial paramagnetic phase, and at large twist angles, they are in a ferromagnetic phase.

description: The sports are growing everywhere in the world, so there is no other way to maintain or to increase the level of quality just the strategic planned development (GÉCZI, 2012), because thousands of specialist are working hardly on the better results worldwide. The aim of this study was to monitor the ice hockey players’ physical development in Hungary since 2007, focusing the results after opening the federations’ Methodical Center (MC). One can see a remarkable development during the last years in the domestic ice hockey, which is perceptible following the sport performance and results. The first step of the planned development was the reform of the curriculum in the coaches courses (from 2004 continuously) at every level, the second step was the opening our MC in 2010, where the Hungarian players and experts (coaches and officials) can develop their skills and their knowledge about the ice hockey. We examined the effect of the above mentioned procedures, comparing the national try-out test running events (10 m, 60 m, 6×9 m, 400 m, 1500 m) by the best twenty U18 players (N=80). According to the opening of the Methodical Center, we used the data from 2012, 2009, 2008 and 2007.

description: I consider the fulfillment of conservation laws and Ward identities in the one- and two-loop functional renormalization group approach. It is shown that in a one-particle irreducible scheme of this approach Ward identities are fulfilled only with the accuracy of the neglected two-loop terms O(V^3) at one-loop order, and with the accuracy O(V^4) at two-loop order (V is the effective interaction vertex at scale Λ). The one-particle self-consistent version of the two-loop RG equations which leads to smaller errors in Ward identities due to the absence of the terms with non-overlapping loops, is proposed. In particular, these modified equations exactly satisfy Ward identities in the ladder approximation.

description: We investigate the feedback of the stellar jets on the surrounding interstellar gas based on 2D and 3D simulations applying HD and MHD module of PLUTO 4.2 code. The main question we address is whether the stellar jet can be considered as a turbulence driver into the interstellar gas. In addition, we investigate the most effective circumstances in which the driven turbulence is larger and can survive for a longer time scale in the ambient gas. We present a case study of different parameters runs including the jet Mach number, the initial jet velocity field and the background magnetic field geometries and the interacting jets. Also, we study the environmental effects on the jet-gas interaction by considering the non-homogeneous surrounding gas containing the clumps in the model setup. Among different setups, we find that for (1) a higher jet Mach number, (2) a rotating jet, 16 pages(3) a jet propagating in a magnetized environment, (4)a jet propagating in a non-homogeneous environment, and (5) the interacting jets more fluctuations and random motions are produced in the entrained gas which can survive for a longer time scale. In addition, we perform the 3D simulations of jet-ambient gas interaction and we find that the amount of (subsonic-supersonic) fluctuations increases compared to the axisymmetric run and the entrained gas gains higher velocities in a 3D run. In total, we confirm the previous finding that the stellar jets can transfer the turbulence on neighboring regions and are not sufficient drivers of the large-scale supersonic turbulence in molecular clouds.

description: The proportion of Hungarian citizens involved in regular physical activity is extremely low and rates are even lower amongst people with disabilities. It is, however, undoubtedly easier to stimulate physical activity if a wide variety of different sports is accessible for them. Blind futsal was introduced by an NGO, Sports and Leisure Association for the Visually Impaired and it has been played in Hungary for only a year. The present work, by introducing this special sport through document analysis and semi-structured interviews, aims at calling sport professionals’ attention to the unexploited opportunities of adapting sports to blind people’s special needs. The author also wishes to highlight the power of a civil initiative and the inmense effort people with visual impairments themselves make for improving their own sporting opportunities.

While our results for the non-perturbative number liberation coefficient agree, those for the energy disagree by a factor of 2. This discrepancy can be traced to an overall normalization error in our non-perturbative formula for the energy. When corrected for, all previous results are in excellent agreement with those of Lappi. The implications of the results of these two independent computations for RHIC phenomenology are noted.

description: Every year, a significant amount of renewable dendromass is generated in Hungary. Various possibilities have been recognised by today that are not widespread yet. The greatest obstacle is frequently derived from the lack of the farmers’ knowledge as without having the required knowledge obtained they can become distrustful or adequate efficiency will not be achieved during utilisation. In order to improve the rate of utilisation, targeted information methodologies should be applied that comply with the farmers’ knowledge. In this present study, the awareness and acceptance of vine-growers from the Micro-region of Gyöngyös related to the use of vine branches will be analysed based on the results of a questionnaire survey. The survey was conducted in accordance with the number of wine-community members in personal interviews. The questionnaire contained questions about the farm, the use of vine branches as well as about the farmers. Based on the results, information was obtained on the reasons for the use of by-products not being wide-spread among farmers as well as on the sources of information obtained. For the fragmented farms which are typical here it is important to know whether by-products are not utilised as it is not how they can be used or whether the vineyard is cultivated by others therefore the farmer lacks machinery. The level of acceptance was also studied by asking a question on the possible offer of the by-products for greater-scale site. Our intention is to assist the generally badly off farmers to use the annually generated by-products in a reasonable way. This can be realized by various ways of providing information. By applying the results of the survey, adequate methods and knowledge can be provided for farmers.

description: We study phonon emission in a GaAs/AlGaAs double quantum dot by monitoring the tunneling of a single electron between the two dots. We prepare the system such that a known amount of energy is emitted in the transition process. The energy is converted into lattice vibrations and the resulting tunneling rate depends strongly on the phonon scattering and its effective phonon spectral density. We are able to fit the measured transition rates and see imprints of interference of phonons with themselves causing oscillations in the transition rates.

There is glaring inequality in Indian society based on caste, class, gender,and region across the Indian society. The paper is an attempt to present a spatial analysis basedon levels of attainment in higher education across India. Analysis reveals that there is a largespatial variation in the attainment rate of higher education among different sections of thesociety across the Indian states/UTs. However, the female attainment rate is comparativelybetter at the postgraduate level of higher education which is a positive sign of womenempowerment.

description: The north east shell of SN 1006 is the most probable acceleration site of high energy electrons (up to ~ 100 TeV) with the Fermi acceleration mechanism at the shock front. We resolved non-thermal filaments from thermal emission in the shell with the excellent spatial resolution of Chandra. The thermal component is extended widely over about ~ 100 arcsec (about 1 pc at 1.8 kpc distance) in width, consistent with the shock width derived from the Sedov solution. The spectrum is fitted with a thin thermal plasma of kT = 0.24 keV in non-equilibrium ionization (NEI), typical for a young SNR. The non-thermal filaments are likely thin sheets with the scale widths of ~ 4 arcsec (0.04 pc) and ~ 20 arcsec (0.2 pc) at upstream and downstream, respectively. The spectra of the filaments are fitted with a power-law function of index 2.1--2.3, with no significant variation from position to position. In a standard diffusive shock acceleration (DSA) model, the extremely small scale length in upstream requires the magnetic field nearly perpendicular to the shock normal. The injection efficiency (eta) from thermal to non-thermal electrons around the shock front is estimated to be ~ 1e-3 under the assumption that the magnetic field in upstream is 10 micro G. In the filaments, the energy densities of the magnetic field and non-thermal electrons are similar to each other, and both are slightly smaller than that of thermal electrons. in the same order for each other. These results suggest that the acceleration occur in more compact region with larger efficiency than previous studies.

description: After the 1989-1990 political changes the aim of the Hungarian University Sports Federation was to follow its traditions of nine decades in foreign policy as well, therefore the organization of international competitions in Hungary was promoted. Up to now the study of the management of these international events was neglected in the Hungarian scholarly literature, although all university sporting events held in Hungary were successful and they were highly appreciated internationally. Taking the example of three university world championships hosted by Hungarian towns, the objective of this paper is to analyze how the management succeeded to solve the major tasks of the organizational work and how some management theories were implemented in its activity. In order to collect data the following methods were used: analysis of documents, in-depth interviews and participant observation. The results are presented on the basis of some theses of the event planning theory, the event management theory, and the situational leadership theory. More specifically, the issues of motives-decisionactions, consistency- coherency- harmony and these of the quantity indicators of event organization in connection of the three underscored world championships organized in Hungary are discussed. In conclusion it is stated that in the management the situation theory had to be taken into consideration the most in the leading process. It was proven that despite preparations lasting often for several years and expanding to every detail of requirements, the flexibility of the management was crucial to search and to find response to every critical situation.

description: „Polens wilder Westen" – so der Titel einer 2013 erschienenen Arbeit von Beata Halicka, in der es um die kulturelle Aneignung des polnischen Oderraums nach 1945 geht. [1] Eine organisierte Propagandakampagne sollte der Bevölkerung seinerzeit das Bild einer Rückkehr in uralte polnische Gebiete, die „polnischen Mutterländer", vermitteln. Stützen konnten sich die neuen Machthaber dabei auf Arbeiten der polnischen Westforschung der Zwischenkriegszeit, die von einer historischen Polonität der Gebiete östlich von Oder und Neiße ausging. Während die praktische Umsetzung dieses polnischen „Westgedankens" nach 1945 im Zentrum mehrerer Studien der vergangenen Jahre stand, nimmt Gernot Briesewitz nun in komplexer Weise die zugrundeliegenden Theorien und die Diskussionen in den Blick, die zwischen 1918 und 1948 von polnischen Wissenschaftlern unterschiedlichster Disziplinen geführt wurden. [2] Dabei wird schnell augenfällig, dass der von Gregor Thum und anderen konstatierte Einfluss des Westgedankens auf die territoriale Gestalt ebenso wie die Beschwörung eines tausendjährigen deutsch-polnischen Gegensatzes und polnischen Kampfes um die „piastischen Gebiete" nur einer von vielen Erzählsträngen war. Das Innovative an der vorliegenden Arbeit ist ihre Fokussierung auf die „Westforschung als Raumkonstrukteurin" (27), während frühere Arbeiten hauptsächlich Institutionen, Akteure und die politische Instrumentalisierung des polnischen Westgedankens in den Blick genommen haben.

description: Um Unit-Testing zu erleichtern, kann es notwendig sein, Produktionscode umzustrukturieren, etwa durch Erweiterung des Zugriffs auf Methoden oder Zerlegung von Klassen in kleinere, leichter testbare Einheiten. Wir analysierten 346.841 Java-Pull-Requests aus 621 GitHub-Projekten, um solche Testbarkeits-Refaktorisierungen zu verstehen. Pull-Requests mit Änderungen in sowohl Produktionsals auch Testcode wiesen signifikant mehr atomare Refaktorisierungen auf, wie „Variablentyp ändern“ oder „Parametertyp ändern“. Manuell analysierten wir 200 Pull-Requests, in denen „Testbarkeit“ oder „Refaktor + Test“ erwähnt wurde, und identifizierten zehn Muster zur Verbesserung der Testbarkeit. In weiteren 524 Pull-Requests, die potenziell Testbarkeitsrefaktorierungen enthielten, fanden wir, dass 25% tatsächlich diese Muster aufwiesen. Häufig waren Methodenauslagerungen und Zugriffserweiterungen.

description: Following the recent claimed obsevation of Nagaoka ferromagnetism in finite size quantum dot plaquettes, a general theoretical analysis is warranted in order to ascertain in rather generic terms which arrangements of a small number of quantum dots can produce saturated ferromagnetic ground states and under which constraints on interaction and inter-dot tunneling in the plaquette. This is particularly necessary since Nagaoka ferromagnetism is fragile and arises only under rather special conditions. We test the robustness of ground state ferromagnetism in the presence of a long-range Coulomb interaction and long-range as well as short-range interdot hopping by modeling a wide range of different plaquette geometries accessible by arranging a few (~4) quantum dots in a controlled manner. We find that ferromagnetism is robust to the presence of long range Coulomb interactions, and we develop conditions constraining the tunneling strength such that the ground state is ferromagnetic. Additionally, we predict the presence of a partially spin-polarized ferromagnetic state for 4 electrons in a Y-shaped 4-quantum dot plaquette. Finally, we consider 4 electrons in a ring of 5 dots. This does not satisfy the Nagaoka condition, however, we show that the ground state is spin one for strong, but not infinite, onsite interaction. Thus, even though Nagaoka's theorem does not apply, the ground state for the finite system with one hole in a ring of 5 dots is partially ferromagnetic. We provide detailed fully analytical results for the existence or not of ferromagnetic ground states in several quantum dot geometries which can be studied in currently available coupled quantum dot systems.

description: Colicin D is a plasmid-encoded bacteriocin that specifically cleaves tRNAArg of sensitive Escherichia coli cells. E. coli has four isoaccepting tRNAArgs; the cleavage occurs at the 3′ end of anticodon-loop, leading to translation impairment in the sensitive cells. tRNAs form a common L-shaped structure and have many conserved nucleotides that limit tRNA identity elements. How colicin D selects tRNAArgs from the tRNA pool of sensitive E. coli cells is therefore intriguing. Here, we reveal the recognition mechanism of colicin D via biochemical analyses as well as structural modelling. Colicin D recognizes tRNAArgICG, the most abundant species of E. coli tRNAArgs, at its anticodon-loop and D-arm, and selects it as the most preferred substrate by distinguishing its anticodon-loop sequence from that of others. It has been assumed that translation impairment is caused by a decrease in intact tRNA molecules due to cleavage. However, we found that intracellular levels of intact tRNAArgICG do not determine the viability of sensitive cells after such cleavage; rather, an accumulation of cleaved ones does. Cleaved tRNAArgICG dominant-negatively impairs translation in vitro. Moreover, we revealed that EF-Tu, which is required for the delivery of tRNAs, does not compete with colicin D for binding tRNAArgICG, which is consistent with our structural model. Finally, elevation of cleaved tRNAArgICG level decreases the viability of sensitive cells. These results suggest that cleaved tRNAArgICG transiently occupies ribosomal A-site in an EF-Tu-dependent manner, leading to translation impairment. The strategy should also be applicable to other tRNA-targeting RNases, as they, too, recognize anticodon-loops.

description: We use a combination of data from the MaNGA survey and MaNGA-like observations in IllustrisTNG100 to determine the prevalence of misalignment between the rotational axes of stars and gas. This census paper outlines the typical characteristics of misaligned galaxies in both observations and simulations to determine their fundamental relationship with morphology and angular momentum. We present a sample of ~4500 galaxies from MaNGA with kinematic classifications which we use to demonstrate that the prevalence of misalignment is strongly dependent on morphology. The misaligned fraction sharply increases going to earlier morphologies (28$\pm$3% of 301 early-type galaxies, 10$\pm$1% of 677 lenticulars and 5.4$\pm$0.6% of 1634 pure late-type galaxies). For early-types, aligned galaxies are less massive than the misaligned sample whereas this trend reverses for lenticulars and pure late-types. We also find that decoupling depends on group membership for early-types with centrals more likely to be decoupled than satellites. We demonstrate that misaligned galaxies have similar stellar angular momentum to galaxies without gas rotation, much lower than aligned galaxies. Misaligned galaxies also have a lower gas mass than the aligned, indicative that gas loss is a crucial step in decoupling star-gas rotation. Through comparison to a mock MaNGA sample, we find that the strong trends with morphology and angular momentum hold true in IllustrisTNG100. We demonstrate that the lowered angular momentum is, however, not a transient property and that the likelihood of star-gas misalignment at z = 0 is correlated with the spin of the dark matter halo going back to z = 1.
