description: Context. Recent observations by the Extreme Ultraviolet Imager (EUI) on board Solar Orbiter have characterized prevalent small-scale transient brightenings in the corona above the quiet Sun termed campfires. Aims. In this study we search for comparable brightenings in a numerical model and then investigate their relation to the magnetic field and the processes that drive these events. Methods. We use the MURaM code to solve the 3D radiation MHD equations in a box that stretches from the upper convection zone to the corona. The model self-consistently produces a supergranular network of the magnetic field and a hot corona above this quiet Sun. For the comparison with the model we synthesize the coronal emission as seen by EUI in its 174 Å channel, isolate the seven strongest transient brightenings, and investigate (the changes of) the magnetic field in and around these in detail. Results. The transients we isolate have a lifetime of about 2 minutes and are elongated loop-like features with lengths around 1Mm to 4 Mm. They tend to occur at heights of about 2Mm to 5Mm above the photosphere a bit offset from magnetic concentrations that mark the bright chromospheric network and they reach temperatures of above 1 MK. With this they very much resemble the (larger) campfires found in observations. In our model most events are energised by component reconnection between (bundles of) field lines that interact at coronal heights. In one case we find that untwisting of a highly twisted flux rope initiates the heating. Conclusions. Based on our study we propose that the majority of campfire events found by EUI are driven by component reconnection and our model suggests that this process contributes significantly to the heating of the corona above the quiet Sun.

Year: 2023

Buildings account for around 40% of energy demand across the globe. Recent decades have witnessed a surge of building-level communication, control, and electrification, which unlock a large set of distributed resources to enhance flexibility and resilience performance. Although these unexplored resources have great potential to improve building-to-grid integration, the existing energy management systems are less supportive and must be holistically redesigned in order to address the building-level challenges such as high-precision simulation, standardized modelling, automatic control, and cost-benefit trade-off issues. This panel will discuss the latest advances in modern grid-interactive buildings which are able to provide grid support functions, including energy balancing, energy sharing, voltage regulation, and resilience services. Speakers will be invited to share their global experiences in this area, with specific focus in deep learning, cloud computing, advanced demand response, resilience enhancement, flexibility pricing, and market design.
Presentations in this panel session:

description: The aim of the proposed CERN Gamma Factory is to produce $\sim 10^{17}$ photons per second with energies up to 400 MeV. The photon beam intensity is expected to be a factor of $\mathcal{O}(10^7)$ larger than that of the presently available photon beams in the MeV energy range. In this work, we explore its potential to probe physics beyond the Standard Model. In particular, we discuss searches for axion like particles (ALPs) with dominant couplings to photons and consider various production scenarios - fixed target, photon-photon collision, and conversion by a magnetic field and detection schemes - via decay to photons or back-conversion. We find that the Gamma Factory in a fixed target mode can probe ALPs with mass $m_a \lesssim \mathcal{O}(100\,\mathrm{MeV})$ and decay constants larger than $10^7$ GeV, improving by an order of magnitude the discovery potential of previous beam dump experiments.

The preservation of urban woodlands : a case study of the University Endowment Lands, Vancouver, B.C.
Creators: name: Rida, Carmen Riina
Publisher: name: University of British Columbia
Year: 2010

description: The goal of this thesis was to show how urban woodlands play an important function in meeting the recreational, educational and other needs of urban populations, enhancing the quality of life in the city. This was achieved in four steps: (1) by describing the historical evolution of the establishment of trees and woodlands in cities, which occurred as urban populations, particularly in Europe, came to perceive trees and woodlands as a necessary and integral component of urban landscapes; (2) by establishing a comprehensive rationale for the preservation of urban woodlands, based on their important function in providing contact with nature and associated benefits that may otherwise be unavailable to urban populations, yet necessary for an enhanced quality of life in built-up urban environments; (3) by looking at various examples of urban woodlands and forest parks that have been established in various cities but especially in Europe, showing how these cities have recognized the value of integrating woodlands into urban environments and ensuring that urban residents are able to take advantage of the many opportunities they provide; and (4) by undertaking a case study of a local example of an urban woodland, the University Endowment Lands (UEL) woodland in Vancouver, British Columbia, and examining its natural attributes and opportunities to users which make it valuable as a recreational and educational resource, and therefore, worthy of preservation. The UEL woodland is a potential future urban forest park, pending the settlement of current discussions and negotiations over the status and allocation of this vacant Crown land. It was concluded that as an urban forest park, the UEL would not only complement the present urban woodland system of the Greater Vancouver area but also stand out as a unique urban natural area with few parallels elsewhere in urbanized North America, perhaps even the world. Its size and location within a completely urbanized area, combined with its extensive forest cover on primarily level or gently undulating topography, are enough to make the UEL woodland unique, but it also features canyons and cliffs, meadows, water courses, and a diversity of vegetation and habitat types growing in a relatively undisturbed state, with development limited only to a network of well-maintained trails in the forest, and access roads through the forest to the university. Thus, the UEL woodland provides a contrasting experience to the other urban forests and forest parks of Greater Vancouver, and if it is preserved, the opportunity exists to create an urban woodland park unparalleled in scenic and natural values, social benefits, and educational and recreational opportunities.
Z-Boson Decays into Majorana or Dirac (Heavy) Neutrinos

description: We computed the kinematics of Z-boson decay into a heavy-light neutrino pair when the Z-boson is produced at rest in electron-positron collisions, including the subsequent decay of the heavy neutrino into a visible final state containing a charged-lepton. We concentrated on heavy-neutrino masses of order dozens of GeV and the issue of addressing the nature of the neutrinos - Dirac fermions or Majorana fermions. We find that while it is not possible to tell the nature of the heavy and light neutrinos on an event-by-event basis, the nature of the neutrinos can nonetheless be inferred given a large-enough sample of heavy-light neutrino pairs. We identify two observables sensitive to the nature of neutrinos. One is the forward-backward asymmetry of the daughter-charged-leptons. This asymmetry is exactly zero if the neutrinos are Majorana fermions and is non-zero (and opposite) for positively- and negatively-charged daughter-leptons if the neutrinos are Dirac fermions. The other observable is the polarization of the heavy neutrino, imprinted in the laboratory-frame energy distribution of the daughter-charged-leptons. Dirac neutrinos and antineutrinos produced in electron-positron collisions at the Z-pole are strongly polarized while Majorana neutrinos are at most as polarized as the $Z$-bosons.

Publisher: name: IEEE
Year: 2023

Advanced Distribution Management Systems (ADMS) have become more widespread to manage the electrical distribution grid at utilities. Integration of ADMS has been occurring without the ADMS being able to completely account for the impact of the proliferation of Distributed Energy Resources (DERs), microgrids, Distributed Energy Resource Management Systems and EVs and how these systems will integrate with requirements such as FERC 2222. Currently, these systems are handled as separate entities with little coordination among them. Efficient and effective management of the electric distribution system requires an integrated approach to allow various systems to work in harmony. The objective of this panel is to: ï Identify the needs of various stakeholders from an integrated system perspective ï Identify the gaps in the integration of DMS, DERs, EVs, and microgrids ï Discuss the architecture of the integrated system (functions, communication, control, interoperability) ï Establish the relationship between different components for enabling them to support grid services and market participation through integrated DERs ï Provide support services to both transmission and distribution grids ï Support large-scale integration of EVs in the distribution grid

description: On the quantum stage spacetime had the foam-like structure. When the Universe cools, the foam structure tempers and does not disappear. We show that effects caused by the foamed structure mimic very well the observed Dark Matter phenomena. Moreover, we show that in a foamed space photons undergo a chaotic scattering and together with every discrete source of radiation we should observe a diffuse halo. We show that the distribution of the diffuse halo of radiation around a point-like source repeats exactly the distribution of dark matter around the same source, i.e. the DM halos are sources of the diffuse radiation.

Modeling, control, estimation and monitoring of Behind the Meter Distributed Energy Resources (BTM DERs) to support decarbonization, demand response and other objectives is becoming increasingly data driven. However, field data from BTM DERs often lack adequate data coverage, quality, documentation, and standardization. This panel will discuss recent efforts on making BTM DER datasets widely available by addressing associated challenges, as well as demonstrate recent high impact uses cases from such datasets. A diversity of perspectives on this theme will be presented from academia, National labs and industry, with an underlying aim to leverage these efforts not only to increase access to high quality datasets, but also maximize the value proposition that can be extracted from them in the context of BTM DERs. The format consists of a set of invited presentations followed by a panel discussion with an opportunity for the audience to directly interact with the panelists.

description: An upper limit on the total annihilation cross section of dark matter (DM) has recently been derived from the observed atmospheric neutrino background. We show that comparable bounds are obtained for DM masses around the TeV scale by observations of the diffuse gamma-ray flux by EGRET, because electroweak bremsstrahlung leads to non-negligible electromagnetic branching ratios, even if DM particles only couple to neutrinos at tree level. A better mapping and the partial resolution of the diffuse gamma-ray background into astrophysical sources by the GLAST satellite will improve this bound in the near future.

description: A novel approximation scheme is proposed to describe the dynamics of the spin-boson problem. Being nonperturbative in the coupling strength nor in the tunneling frequency, it gives reliable results over a wide regime of temperatures and coupling strength to the thermal environment for a large class of bath spectral densities. We use a path-integral approach and start from the exact solution for the two-level system population difference in the form of a generalized master equation (GME). Then, we approximate inter-blip and blip-sojourns interactions up to linear order, while retaining all intra-blip correlations to find the kernels entering the GME in analytical form. Our approximation scheme, which we call Weakly-Interacting Blip Approximation (WIBA), fully agrees with conventional perturbative approximations in the tunneling matrix element (Non-Interacting Blip Approximation) or in the system-bath coupling strength.

description: We study how iterated convolutions of probability measures compare under stochastic domination. We give necessary and sufficient conditions for the existence of an integer $n$ such that $μ^{*n}$ is stochastically dominated by $ν^{*n}$ for two given probability measures $μ$ and $ν$. As a consequence we obtain a similar theorem on the majorization order for vectors in $\R^d$. In particular we prove results about catalysis in quantum information theory.
Footprints of the Beyond in flavor physics: Possible role of the Top Two Higgs Doublet Model

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The B-factories results provide an impressive confirmation of the Standard Model (SM) description of flavor and CP violation. Nevertheless, as more data were accumulated, deviations in the 2.5-3.5 sigma range have emerged pointing to the exciting possibility of new CP-odd phase(s) and flavor violating parameters in B-decays. Primarily this seems to be the case in the time dependent CP asymmetries in penguin dominated modes (e.g. B -> phi (eta') Ks). We discuss these and other deviations from the SM and, as an illustration of possible new physics scenarios, we examine the role of the Top Two Higgs Doublet Model. This is a simple extension of the SM obtained by adding second Higgs doublet in which the Yukawa interactions of the two Higgs doublets are assigned in order to naturally account for the large top-quark mass. Of course, many other extensions of the Standard Model could also account for these experimental deviations. Clearly if one takes these deviations seriously then some new particles in the 300 GeV to few TeV with associated new CP-odd phase(s) are needed.

description: Single walled carbon nanotubes exhibit advanced electrical and surface properties useful for high performance nanoelectronics. Important to future manufacturing of nanotube circuits is large scale assembly of SWNTs into aligned forms. Despite progress in assembly and oriented synthesis, pristine SWNTs in aligned and close-packed form remain elusive and needed for high current, speed and density devices through collective operations of parallel SWNTs. Here, we develop a Langmuir Blodgett method achieving monolayers of aligned SWNTs with dense packing, central to which is a non covalent polymer functionalization by PmPV imparting high solubility and stability of SWNTs in an organic solvent DCE. Pressure cycling or annealing during LB film compression reduces hysteresis and facilitates high degree alignment and packing of SWNTs characterized by microscopy and polarized Raman spectroscopy. The monolayer SWNTs are readily patterned for device integration by microfabrication, enabling the highest currents 3mA through the narrowest regions packed with aligned SWNTs thus far.

description: The study on the shock formation and the regularities of the resulting shock surfaces for hyperbolic conservation laws is a basic problem in the nonlinear partial differential equations. In this paper, we are concerned with the shock formation and the optimal regularities of the resulting shock curves for the 1-D conservation law $\partial_tu+\partial_xf(u)=0$ with the smooth initial data $u(0,x)=u_0(x)$. If $u_0(x)\in C^{1}(\Bbb R)$ and $f(u)\in C^2(\Bbb R)$, it is well-known that the solution $u$ will blow up on the time $T^*=-\frac{1}{\min{g'(x)}}$ when $\min{g'(x)}<0$ holds for $g(x)=f'(u_0(x))$. Let $x_0$ be a local minimum point of $g'(x)$ such that $g'(x_0)=\min{g'(x)}<0$ and $g''(x_0)=0$, $g^{(3)}(x_0)>0$ (which is called the generic nondegenerate condition), then by Theorem 2 of \cite{Le94}, a weak entropy solution $u$ together with the shock curve $x=φ(t)\in C^2[T^*, T^*+\varepsilon)$ starting from the blowup point $(T^*, x^*=x_0+g(x_0)T^*)$ can be locally constructed. When the generic nondegenerate condition is violated, namely, when $x_0$ is a local minimum point of $g'(x)$ such that $g''(x_0)=g^{(3)}(x_0)=...=g^{(2k_0)}(x_0)=0$ but $g^{(2k_0+1)}(x_0)>0$ for some $k_0\in\Bbb N$ with $k_0\ge 2$; or $g^{(k)}(x_0)=0$ for any $k\in\Bbb N$ and $k\ge 2$, we will study the shock formation and the optimal regularity of the shock curve $x=φ(t)$, meanwhile, some precise descriptions on the behaviors of $u$ near the blowup point $(T^*, x^*)$ are given. Our main aims are to show that: around the blowup point, the shock really appears whether the initial data are degenerate with finite orders or with infinite orders; the optimal regularities of the shock solution and the resulting shock curve have the explicit relations with the degenerate degrees of the initial data.

Wildfire has emerged as a significant risk to society in many places throughout the world. The increased risk is fueled by climate change and its associated elevation of drought and extreme weather. While most ignitions are caused by humans, electric power line ignitions are also contributing factors to the growing problem. Today, advanced power system protection technologies are being developed to help mitigate and reduce the risk of power line wildfire ignitions. Significant efforts are going on in the industry to develop, test, and deploy new protection schemes.

description: Kartoffeln müssen wegen ihrer vielfältigen Verwendungsmöglichkeiten im Vergleich zu anderen Kulturen eine Vielzahl von Qualitätskriterien erfüllen. Produkte des ökologischen Anbaues werden im Vergleich zu konventionell erzeugten Produkten häufig als qualitativ hochwertiger erachtet. Wichtige Qualitätsmerkmale der Kartoffel sind deren Festigkeitseigenschaften. Das hier vorgestellte Messverfahren erlaubt diese Merkmale objektiv zu ermitteln. Der Stempeltest wurde in der DFG-Forschergruppe Optimierungsstrategien im Organischen Landbau (OSIOL) eingesetzt, um den Einfluss verschiedener Versuchsfaktoren auf dessen Festigkeitskennwert zu prüfen.

Quantitative structural and textural assessment of laminar pyrocarbons through Raman spectroscopy, electron diffraction and few other techniques

description: In pyrocarbon materials, the width of the Raman D band (FWHMD) is very sensitive to low energy structural defects (e.g., disorientations of the graphene layers). The correlation between the two parameters, FWHMD and OA (as derived from selected area electron diffraction: SAED), has allowed to differentiate various pyrocarbons unambiguously. Furthermore, the optical properties of pyrocarbons, i.e., the extinction angle, the optical phase shift and the ordinary and extraordinary reflectance, have been accurately determined at 550 nm by means of the extinction curves method. These results are completed by in-plane and out-of-plane dielectric constant measurements by angular resolved EELS. Moreover, the hybridization degree of the carbon atoms has been assessed by the same technique. About 80% of the carbon atoms of the pyrocarbons have a sp2 hybridization. The lack of pure sp2 carbon atoms, as compared to graphite, might be explained by the presence of sp3-like line defects.

Advanced Grid Operations
Creators: D. Shi
Publisher: name: IEEE
Year: 2023

Reliability and stability of the electric grid today has depended upon operations of the grid which include the protective relay. Today, the electricity sector faces new challenges with the shift of generation resource characteristics away from the traditional ìbig ironî generation to inverter-based resources (IBR) which shift the physics and assumption used in grid operation and protection. These changing conditions represent new challenges for protective relays (identification of faults) and increased challenges for protection engineers (correct settings and configuration, reduction of mis-operations), both issues recognized in research and industry. Finding new approaches to reduce mis-operations in relaying and new approaches to fault identification is critical to grid operations. Using todayís modern technology of embedded systems, edge computing, machine learning (ML), and communications we can help address challenges and augment and improve on existing power system operations methodologies.

An evaluation framework for citizen participation in urban transportation planning
Creators: name: Innes, Robert George
Publisher: name: University of British Columbia
Year: 2010

description: Although the planning and implementation of recent transportation projects have attempted to involve the public at critical stages, the persistence of conflicts between an efficient metropolitan transportation system and the needs of residents of the quiet enjoyment of their communities suggests the need to study and evaluate the effectiveness of participatory planning. This thesis explores the role of citizen participation in urban transportation planning and proposes an evaluation framework which is tested through its application to two recent transportation projects. This framework includes nine requisites for effective citizen participation which were drawn from the literature and the review of other related transportation case studies. These requisites relate to: •Objectives Defined •Good Timing •Effective Communications •Accessibility to the Process •Government Responsiveness •Community Representation •Commitment •Credibility •Flexibility By drawing on the experiences and perceptions of key participants of each case, the thesis assessed the effectiveness of each program. An evaluation matrix which is also based on these requisites is also proposed as a planning tool. The framework is tested through its application to the Cassiar Street Connector case in Vancouver and the Kensington Avenue Overpass project in Burnaby. Selected participants covering the local community, and appointed and elected municipal and provincial officials who were involved in each case were interviewed. Through their perceptions and insights, the framework was used to assess the effectiveness of the citizen participation component of the case. Results suggest that the framework can be considered a positive step towards a more general framework and towards a general improvement in the field of evaluation. While not a conclusive or exhaustive list of requisites, the framework does offer the advantage of including those requisites which, according to both the literature and the interviewees, are fundamental to participatory planning. The proposed matrix should be considered as an effective planning tool which allows for evaluation and monitoring complete participation programs as well as focussing on a specific requisite. Furthermore, it can be used as both an interim and final report card on a citizen participation program. The matrix also lends itself to a spreadsheet application. The thesis suggests the importance of a well defined organizational structure for citizen participation such as an advisory body or supervisory committee. These structures appear to offer advantages in providing a forum for the major participants, including the affected communities, to participate effectively in the planning process. Furthermore, the thesis recommends that the Provincial Ministry of Transportation and Highways' transportation planning efforts would benefit from a strong public consultation function, to complement its engineering and technical mandates.

description: We study the S=1/2 Heisenberg antiferromagnet on a square lattice with nearest-neighbor and plaquette four-spin exchanges (introduced by A.W. Sandvik, Phys. Rev. Lett. {\bf 98}, 227202 (2007).) This model undergoes a quantum phase transition from a spontaneously dimerized phase to Néel order at a critical coupling. We show that as the critical point is approached from the dimerized side, the system exhibits strong fluctuations in the dimer background, reflected in the presence of a low-energy singlet mode, with a simultaneous rise in the triplet quasiparticle density. We find that both singlet and triplet modes of high density condense at the transition, signaling restoration of lattice symmetry. In our approach, which goes beyond mean-field theory in terms of the triplet excitations, the transition appears sharp; however since our method breaks down near the critical point, we argue that we cannot make a definite conclusion regarding the order of the transition.
