The J- and H-bands of dye aggregate spectra: Analysis of the coherent exciton scattering (CES) approximation

description: The validity of the CES approximation is investigated by comparison with direct diagonalisation of a model vibronic Hamiltonian of $N$ identical monomers interacting electronically. Even for quite short aggregates (N\gtrsim 6) the CES approximation is shown to give results in agreement with direct diagonalisation, for all coupling strengths, except that of intermediate positive coupling (the H-band region). However, previously excellent agreement of CES calculations and measured spectra in the H-band region was obtained [A. Eisfeld, J. S. Briggs, Chem. Phys. 324, 376]. This is shown to arise from use of the measured monomer spectrum which includes implicitly dissipative effects not present in the model calculation.

description: We examine general Gottesman-Kitaev-Preskill (GKP) codes for continuous-variable quantum error correction, including concatenated GKP codes, through the lens of lattice theory, in order to better understand the structure of this class of stabilizer codes. We derive formal bounds on code parameters, show how different decoding strategies are precisely related, propose new ways to obtain GKP codes by means of glued lattices and the tensor product of lattices and point to natural resource savings that have remained hidden in recent approaches. We present general results that we illustrate through examples taken from different classes of codes, including scaled self-dual GKP codes and the concatenated surface-GKP code.

description: We present series study of using the method of super-symmetric quantum mechanics(SUSYQM) solving the spin-weighted spheroidal wave equation. In this paper, we obtain the first four terms of super-potential of the spin-weighted spheroidal wave equation in the case of s=1. These results may help summary the general form for the n-th term of the super-potential, which is proved correct by means of induction. We finally compute the ground eigenvalues and ground eigenfunction. All the results may be of significative for studies of electromagnetic radiation processes near rotating black holes and compute radiation reaction in curved space-time.

The large collected datasets are of very high quality and have been used to commission and calibrate the CMS detector, with the achieved performance close to the TDR specifications. CMS has reestablished all the major Standard Model processes in the 2010 Run and is entering new territory in searches for New Physics, with sensitivity already exceeding that at LEP and TeVatron.

description: The network interface adapter (NIC) is a critical component of a cloud server occupying a unique position. Not only is network performance vital to efficient operation of the machine, but unlike compute accelerators like GPUs, the network subsystem must react to unpredictable events like the arrival of a network packet and communicate with the appropriate application end point with minimal latency.
 Current approaches to server stacks navigate a trade-off between flexibility, efficiency, and performance: the fastest kernel-bypass approaches dedicate cores to applications, busy-wait on receive queues, etc. while more flexible approaches appropriate to more dynamic workload mixes incur much greater software overhead on the data path.
 However, we reject this trade-off, which we ascribe to an arbitrary (and sub-optimal) split in system state between the OS and the NIC. Instead, by exploiting the properties of cache-coherent interconnects and integrating the NIC closely with the OS kernel, we can achieve something surprising: performance for RPC workloads better than the fastest kernelbypass approaches without sacrificing the robustness and dynamic adaptation of kernel-based network subsystems.

description: The nonlinear acoustic response of low-energy excitations in insulating glasses is investigated using the tunneling model. An explicit evaluation of the sound velocity shift is performed which covers the whole temperature range of recent vibrating-reed experiments. Our results are in excellent agreement with experimental findings. The comparison with recent findings on the nonlinear response in metallic glasses shows that the dynamics of the nonlinear driven tunneling system is qualitatively different for fermionic or bosonic environments. These differences are strongly reflected in the acoustic properties.

description: One of the fundamentals for demonstrating a new language to learners is to examine the culture of the target language. So far, several issues have been identified whenever teaching a new language has not been accompanied with teaching the new culture. This paper describes how to detect socio-cultural aspects in language classes (EFL) for teaching the culture of a new language might help educators improve the quality of their instruction. We view "cultural constituents of the target language" as a significant aspect in learning a new culture in this study. We also need to understand what "socio-cultural stereotype" entails.

description: We develop a "semi-parallel" simulation technique suggested by Pretorius and Lehner, in which the simulation spacetime volume is divided into a large number of small 4-volumes which have only initial and final surfaces. Thus there is no two-way communication between processors, and the 4-volumes can be simulated independently without the use of MPI. This technique allows us to simulate much larger volumes than we otherwise could, because we are not limited by total memory size. No processor time is lost waiting for other processors. We compare a cosmic string simulation we developed using the semi-parallel technique with our previous MPI-based code for several test cases and find a factor of 2.6 improvement in the total amount of processor time required to accomplish the same job for strings evolving in the matter-dominated era.

The scaling of number values in one structure, relative to the values in another structure, must be compensated for by scaling of the basic operations and relations (if any) in the structure. The scaling must be such that one structure satisfies the relevant number type axioms if and only if the other structure does.

description: We study the possibility to replace the anti-neutrino run of a long baseline neutrino oscillation experiment, with anti-neutrinos from muon decay at rest. The low energy of these neutrinos allows the use of inverse beta decay for detection in a Gadolinium-doped water Cerenkov detector. We show that this approach yields a factor of five times larger anti-neutrino event sample. The resulting discovery reaches in theta_13, the mass hierarchy and leptonic CP violation are compared with those from a conventional superbeam experiment with combined neutrino and anti-neutrino running. We find that this approach yields a greatly improved reach for CP violation and theta_13 while leaving the ability to measure the mass hierarchy intact.

description: There has been a range of relevant academic research regarding music education for Deaf students. Such research has highlighted the abilities and strengths of Deaf musicians (Darrow 1993, 1999 and 2006), explored relevant concepts relating to tactile learning (Loeffler 2014) and informed inclusive teaching techniques in music education (Churchill 2015). Relevant work has also been conducted by UK charities (including Music and The Deaf and Drake Music Scotland), providing educational workshops and the creation of platforms and opportunities for Deaf musicians. However, there are still misconceptions regarding Deaf people’s desire and ability to learn music in the UK, which, along with other contributing factors, can affect Deaf students negatively and make many facets of music making and learning less accessible (Padden and Humphries 1990). Additionally, despite the research conducted to date, there is still a lack of research exploring Deaf musicians’ opinions and recommendations on issues of access to music education and inclusive teaching practices in the UK. In response to these issues, semi-structured interviews were conducted with four Deaf musicians/teachers from the UK, all with significant experience of working with Deaf children in musical contexts. Analysis was conducted using Reflexive Thematic Analysis. Results revealed that all participants had positive early experiences of music tuition and were passionate about recreating such experiences for their students. In addition, four key barriers to music education for Deaf children were identified: financial barriers, technological barriers, communication barriers and societal barriers. Several positive and impactful practices currently being utilised by Deaf music teachers in the UK were also identified, such as inclusive, student-centred teaching techniques, signed song, Deaf awareness training and inclusive technology/instruments. Alongside relevant literature, the data gathered from these interviews were utilised to formulate a set of recommendations to address these barriers.

We extend the standard model hadronic current by additional right-handed vector as well as left- and right-handed scalar and tensor contributions and calculate the decay rates including the perturbative corrections up to order $α_s$. Using the data of the exclusive semileptonic $b \to c $ decays and recent calculations of the form factors at the non-recoil point we discuss the constraints to the wrong helicity admixtures in the hadronic current.

description: We report the first detection of molecular hydrogen (H$_{2}$) absorption in the Lyman-$α$ emission line profiles of two classical T Tauri stars (CTTSs), DF Tau and V4046 Sgr, observed by \emph{HST}/COS. This absorption is the energy source for many of the Lyman-band H$_{2}$ fluorescent lines commonly seen in the far-ultraviolet spectra of CTTSs. We find that the absorbed energy in the H$_{2}$ pumping transitions from a portion of the Lyman-$α$ line significantly differ from the amount of energy in the resulting fluorescent emission. By assuming additional absorption in the H I Lyman-$α$ profile along our light of sight, we can correct the H$_{2}$ absorption/emission ratios so that they are close to unity. The required H I absorption for DF Tau is at a velocity close to the radial velocity of the star, consistent with H I absorption in the edge-on disk and interstellar medium. For V4046 Sgr, a nearly face-on system, the required absorption is between +100 km/s and +290 km/s, most likely resulting from H I gas in the accretion columns falling onto the star.

description: Cohesion is a central element in group dynamics that contributes to a team’s functioning and performance. Most of the cohesion research to date has focused on the dynamic within interacting sport teams (i.e., football, basketball, soccer) but has looked past coacting teams (i.e., golf, tennis, cross-country running). While interacting sports command worldwide popularity, a significant portion of student athletes compete in coacting sports and represent the bulk of NCAA affiliated participants on the world stage at the Olympics. Thus, with such status on the world stage of competition, the investigation of coacting sports is justified. Therefore, the purpose of this study was to identify and explain athlete experiences and perceptions of cohesion in a coacting sport such as golf. A case study design was used along with semi-structured open-ended interview format to investigate the topic with six Division I women’s collegiate golfers. Results revealed two higher-order categories which were called team development, and athlete experiences and perceptions. Despite participants unique differences in sporting experience, there were several common themes that emerged, including players acknowledgement that cohesion was a necessary element of team performance, that the strength of interpersonal relationships and positive team dynamic made participants feel an improvement in performance potential, and that intrateam competition and a poorly regulated environment would deteriorate individual and team performance and wellbeing. Moreso, participants discussed their perception of the role team members and coaches fill in contributing to a positive or negative team atmosphere, and how this inevitably influences the prevailing dynamic of intrateam competition and its impact on performance outcomes. Findings from this study provide a greater understanding of the athlete interpretation of cohesion and expand the body of literature on coacting sports generally.

description: Observations of the frequency dependence of the global brightness temperature of the redshifted 21 cm line of neutral hydrogen may be possible with single dipole experiments. In this paper, we develop a Fisher matrix formalism for calculating the sensitivity of such instruments to the 21 cm signal from reionization and the dark ages. We show that rapid reionization histories with duration delta z< 2 can be constrained, provided that local foregrounds can be well modelled by low order polynomials. It is then shown that observations in the range nu = 50 - 100 MHz can feasibly constrain the Lyman alpha and X-ray emissivity of the first stars forming at z = 15 - 25, provided that systematic temperature residuals can be controlled to less than 1 mK. Finally, we demonstrate the difficulty of detecting the 21 cm signal from the dark ages before star formation.

description: The framed little 2-discs operad is homotopy equivalent to a cyclic operad. We show that the derived modular envelope of this cyclic operad (i.e., the modular operad freely generated in a homotopy invariant sense) is homotopy equivalent to the modular operad made from classifying spaces of diffeomorphism groups of 3-dimensional handlebodies with marked discs on their boundaries. A modification of the argument provides a new and elementary proof of K. Costello's theorem that the derived modular envelope of the associative operad is homotopy equivalent to the ``open string'' modular operad made from moduli spaces of Riemann surfaces with marked intervals on the boundary. Our technique also recovers a theorem of C. Braun that the derived modular envelope of the cyclic operad that describes associative algebras with involution is homotopy equivalent to the modular operad made from moduli spaces of unoriented Klein surfaces with open string gluing.

Evaluating the performance-based seismic design of RC bridges according to the 2014 Canadian Highway Bridge Design Code
Creators: name: Ashtari, Sepideh
Publisher: name: University of British Columbia
Year: 2018

description: The 2014 edition of the Canadian Highway Bridge Design Code, CSA S6-14, has adopted a performance-based design approach for the seismic design of lifeline and major-route bridges in highly seismic zones. This addition offers many opportunities as well as some challenges with regards to implementing the CSA S6-14 performance-based design provisions in practice. This thesis aims to identify these challenges through a critical review of the CSA S6-14 performance-based design provisions and to address a number of them within the scope of the thesis. The motivation behind conducting the present study is to prepare a reference document for engineers to better comprehend and implement the new provisions in practice. The focus of the thesis is on the performance-based design of new reinforced concrete bridges with ductile substructures. The addressed challenges are related to CSA S6-14 performance verification framework, calibration of performance criteria, and appropriate numerical models to evaluate the established performance criteria. A deterministic and a probabilistic framework are recommended to be used with the CSA S6-14 performance-based design approach. The applications of each of the frameworks are demonstrated through two detailed case studies and the advantages and disadvantages of each framework are discussed. The performance criteria of the code are compared against the recommended criteria in the literature and other design guidelines. Moreover, the strain limits of the code are examined to predict the damage to a number of tested reinforced concrete bridge columns. A thorough comparison of the CSA S6-14 and the updated strain limits of the BC MoTI Supplement to CSA S6-14 is presented. Finally, common modelling techniques for reinforced concrete structures including distributed and concentrated plasticity models are employed to predict the response of a number of tested bridge columns. Mesh-sensitivity issues due to the localization of plastic strains at critical sections or elements of distributed plasticity models are discussed and the methods to rectify the issue are presented and compared. A simple solution is proposed to eliminate the post-processing effort that is required to verify the strain limits of the code in distributed plasticity models, for which material model regularization is used to deal with the mesh-sensitivity issue.

description: We present predicted Sunyaev-Zeldovich (SZ) properties of known X-ray clusters of galaxies for which gas temperature measurements are available. The reference sample was compiled from the BAX database for X-ray clusters. The Sunyaev-Zeldovich signal is predicted according to two different scaling laws for the mass-temperature relation in clusters: a standard relation and an evolving relation that reproduces well the evolution of the X-ray temperature distribution function in a concordance cosmology. Using a Markov Chain Mote Carlo (MCMC) analysis we examine the values of the recovered parameters and their uncertainties. The evolving case can be clearly distinguished from the non-evolving case, showing that SZ measurements will indeed be efficient in constraining the thermal history of the intra-cluster gas. However, significant bias appears in the measured values of the evolution parameter for high SZ threshold owing to selection effects.

Gaussian resource theories and semidefinite programming hierarchies for quantum information
Creators: name: Jee, Hyejung
Publisher: name: Imperial College London
Year: 2022

description: Determining which quantum tasks we can perform with currently available tools and devices is one of the most important goals of quantum information science today. To achieve this requires careful investigation of the capability of current quantum tools as well as development of classical protocols which can assist quantum tasks and amplify their abilities. In this thesis, we approach this problem through two different topics in quantum information theory: Gaussian resource theories and semidefinite programming hierarchies. In the first part of this thesis, we examine the possibility of implementing quantum information processing tasks in the Gaussian platform through the eyes of quantum resource theories. Gaussian states and operations are primary tools for the study of continuous-variable quantum information processing due to their easy accessibility and concise mathematical descriptions, although it has been discovered that they are subject to a number of limitations for advanced quantum information processing tasks. We explore the capability of the Gaussian platform further in the first part of this thesis. Firstly, we investigate whether introducing convex structure to the Gaussian framework can circumvent the known no-go theorem of Gaussian resource distillation. Surprisingly, we find that resource distillation becomes possible — albeit in a limited fashion — when convexity is introduced. Then, we consider the quantum resource theory of Gaussian thermal operations when catalysts are allowed, and examine the abilities of catalytic Gaussian thermal operations by characterising all possible state transformations under them. In the second part of this thesis, we address the problem of characterising quantum cor- relations via semidefinite programming hierarchies. In particular, we focus on characterising quantum correlations of fixed dimension, which is practically relevant to the field of semi- device-independent quantum information processing. Semidefinite programming is a special type of mathematical optimisation, and it is known that some important but difficult problems in quantum information theory admit semidefinite programming relaxations; these include the characterisation of general quantum correlations in the context of non-locality and the distinction of quantum separable states from entangled states. In this second part, we show how to construct a hierarchy of semidefinite programming relaxations for quantum correlations of fixed dimension and derive analytical bounds on the convergence speed of the hierarchy. For the proof, we make a connection to a variant of quantum separability problem and employ multipartite quantum de Finetti theorems with linear constraints.

Liegen diese Falten im Makulabereich, wirkt sich das meist erheblich auf das Sehvermögen des Patienten aus. Im Folgenden wird eine Behandlungstechnik solcher Falten beschrieben. Methode In einem Zeitraum von Januar 2017 bis Juni 2020 wurden 6 Patienten mit der im Folgenden beschriebenen Behandlungstechnik operiert. Es erfolgte die erneute Abhebung der Netzhaut mittels Balanced Salt Solution (BSS), gefolgt von einer subretinalen Eingabe gefilterter Luft. Das Ausstreichen der Falte erfolgte mithilfe von Perfluorcarbon (PFC). Eine postoperative Drainage der subretinalen Luft und Flüssigkeit erfolgte nicht, die Spontanresorption wurde abgewartet. Ergebnisse Bei keinem Patienten kam es zu einer Visusverschlechterung nach erneuter Netzhautabhebung. Eine Verbesserung der Sehschärfe zeigte sich bei 4 von 6 Fällen. Eine Verminderung der Metamorphopsien konnte bei 5 von 6 Patienten erreicht werden, 2 Patienten gaben an, die Metamorphopsien gar nicht mehr wahrzunehmen. Nur 1 Patient berichtete über einen gleichbleibend verzerrten Seheindruck trotz anatomisch glatter zentraler Netzhaut. Schlussfolgerung Bei kritischer Indikationsstellung stellt unsere Behandlungstechnik eine sichere und erfolgreiche Vorgehensweise zur Behandlung von Netzhautfalten im Bereich der Makula nach Ablatiooperation dar.

description: Abstract:
By the year 2010, the Star Fire mining operation in Knott, Breathitt, and Perry Counties in eastern Kentucky, which uses mountaintop-removal and hollow-fill mining techniques, will have created approximately 5,000 acres of gently rolling terrain that could support alternative land uses. The present research is centered on approximately 1,000 acres of spoil created since mining began in 1981. An aquifer fed by both ground and surface water will be created within the spoil. Spoil-handling techniques such as cast blasting, dragline placement, end dumping by trucks, and surface grading have created porous coarse-rock zones within the spoil through which ground water can move. A vertical rubble chimney in the spoil has been constructed of durable rock to enhance infiltration to the ground-water reservoir through a surface infiltration basin.
Fourteen monitoring wells have been installed along with flumes to gage surface-water discharge and monitor water quantity and quality at the site. Dye-tracing studies have identified ground-water flow paths and flow velocities. A preliminary assessment of the water resources at the site indicates that a stable water table has been created at the mined site. Based on an average saturated thickness of 21 feet for the entire site and an estimated porosity of 20 percent, the spoil stores approximately 4,200 acre-feet (1.37 billion gallons) of water.
Dye-tracing data, hydraulic gradients, and water-quality data indicate that ground water moves more slowly in the spoil's interior; from there it flows down into the hollow fills before discharging as springs along the bottom of the spoil. The springs discharge approximately 1 million gallons per day under normal flow conditions, and discharges of approximately 5 million gallons per day have been measured a week after rainfall events.

description: We study the quantum dynamics of a periodically driven biased two-state system which additionally is subject to either Ohmic or to frequency-dependent damping. Within the noninteracting-blip approximation for the stochastic forces, the solution is given in terms of a series which is defined by recursion relations. Avoiding rotating wave and Markovian approximation, we deduce the solution in closed form for the important cases of high- and low-frequency driving. For low-frequency driving, the dynamics is governed by a rate equation with a time-dependent rate and with a time-dependent adiabatic equilibrium state. In the high-frequency case, we find novel cooperative effects, such as resonances in the spectral distribution near fractional values of the static detuning energy.

description: We study ballistic transport properties of graphene with a low concentration of vacancies or adatoms. The conductance of graphene doped to the Dirac point is found to depend on the relative distribution of impurities among different sites of the honeycomb lattice labeled in general by six colors. The conductivity is shown to be sensitive to the crystal orientation if adatom sites have a preferred color. Our theory is confirmed by numerical simulations using recursive Green's functions with no adjustable parameters.

description: The story of HIV/AIDS and the mining industry in South Africa is complex. It is also more controversial than that of other sectors discussed in this volume. Two interrelated factors account for the particularity of the case. Firstly, mining companies have contributed significantly to the spread of HIV/AIDS through the use of their 120 year-old migrant labor model. At the 2010 HIV/AIDS conference in Durban, the South African gold mining sector came under heavy criticism from medical practitioners, ex-miners, advocacy groups and the South African Minister of Health for its part in the tuberculosis crisis that affects the industry and its workforce. An activist with the Aids and Rights Alliance for Southern Africa referred to the industry as “TB factory”1. The health minister, Mr. Motsoaledi, stated that “[if] TB/HIV is a snake in Southern Africa, we know that its head is in South Africa in the mines. We are exporting TB and HIV throughout the region”.2 Secondly, the mining industry was early in identifying HIV/AIDS as a key risk to its operations. Already in the 2 mid-1980’s initial responses were developed. However, the overall exclusionary nature of these first approaches laid the ground for some of the difficulties in the implementation of comprehensive prevention and treatment policies later on. The analysis of the mining sector provides important insights into the specific political and normative conditions under which companies have historically addressed a problem such as HIV/AIDS in a way that contributes to improved collective goods provision.
Rate of convergence to self-similarity for the fragmentation equation in L^1 spaces

description: In a recent result by the authors (ref. [1]) it was proved that solutions of the self-similar fragmentation equation converge to equilibrium exponentially fast. This was done by showing a spectral gap in weighted $L^2$ spaces of the operator defining the time evolution. In the present work we prove that there is also a spectral gap in weighted $L^1$ spaces, thus extending exponential convergence to a larger set of initial conditions. The main tool is an extension result in ref. [4].

description: We present Swift UVOT (1600-3000A) 3-band photometry for 41 galaxies in 11 nearby (<4500km/s) Hickson Compact Groups (HCGs) of galaxies. We use the uvw2-band (2000A) to estimate the dust-unobscured component, SFR_UV, of the total star-formation rate, SFR_T. We use Spitzer MIPS 24-micron photometry to estimate SFR_IR, the dust-obscured component of SFR_T. We obtain SFR_T=SFR_UV+SFR_IR. Using 2MASS K_s band based stellar mass, M*, estimates, we calculate specific SFRs, SSFR=SFR_T/M*. SSFR values show a clear and significant bimodality, with a gap between low (~1.2x10^-10 / yr) systems. All galaxies with MIR activity index a_IRAC <= 0 (>0) are in the high- (low-) SSFR locus, as expected if high levels of star-formation power MIR emission from polycyclic aromatic hydrocarbon molecules and a hot dust continuum. All elliptical/S0 galaxies are in the low-SSFR locus, while 22 out of 24 spirals/irregulars are in the high-SSFR locus, with two borderline cases. We divide our sample into three subsamples (I, II and III) according to decreasing HI-richness of the parent galaxy group to which a galaxy belongs. Consistent with the SSFR and a_IRAC bimodality, 12 out of 15 type-I (11 out of 12 type-III) galaxies are in the high- (low-) SSFR locus, while type II galaxies span almost the full range of SSFR values. Unlike HCG galaxies, galaxies in a comparison quiescent SINGS sub-sample are continuously distributed both in SSFR and a_IRAC. Any uncertainties can only further enhance the SSFR bimodality. These results suggest that an environment characterized by high galaxy number-densities and low galaxy velocity-dispersions, such as the one found in compact groups, plays a key role in accelerating galaxy evolution by enhancing star-formation processes in galaxies and favoring a fast transition to quiescence.(abridged)

Making tomorrow's stories : the commercial viability and material demands of transmedia narratives for children
Creators: name: Thiboutot, Valerie
Publisher: name: University of British Columbia
Year: 2018

description: This project aims to explore the exciting new trends in multimedia storytelling through an economic lens. Although strongly enthused by the theoretical possibilities of digital technology in multimodal narratives, the academic world seems to turn a blind eye to the harsh material limitations of such artistic endeavors. The apparent discrepancy between the academic conversation on transmedia narratives and the latter’s (lack of) commercial success reveals a significant gap between the literary and media theories surrounding multimedia storytelling and the economics of their production and marketing. This thesis offers to bridge these two realities through an exploratory analysis of the resources needed in the production and promotion of a transmedia narrative designed for children. The project is divided in three stages: a case study of the commercialization of Inanimate Alice as a transmedia narrative for children, an original design of a multimedia narrative for middle grade children, and an assessment of the resources— material, human, and financial—the design would require for its production. The resources assessment at the core of this exploratory research is based on the creative design for a transmedia narrative this project proposes, as a hypothetical commercial and material production. Through the analysis of production concerns for an existing transmedia story as well as a supposed one, this work identifies the array of financial and human challenges that are specific to the transmedia medium. Using Jenkins’ definition of “transmedia narratives” and the current academic discussions on transmedia, this project assesses the resources needed to produce, distribute, and sell a specific transmedia narrative, in order to paint a clearer portrait of the material realities and production challenges faced by transmedia content creators.

description: We introduce the problem Synchronized Planarity. Roughly speaking, its input is a loop-free multi-graph together with synchronization constraints that, e.g., match pairs of vertices of equal degree by providing a bijection between their edges. Synchronized Planarity then asks whether the graph admits a crossing-free embedding into the plane such that the orders of edges around synchronized vertices are consistent. We show, on the one hand, that Synchronized Planarity can be solved in quadratic time, and, on the other hand, that it serves as a powerful modeling language that lets us easily formulate several constrained planarity problems as instances of Synchronized Planarity. In particular, this lets us solve Clustered Planarity in quadratic time, where the most efficient previously known algorithm has an upper bound of O(n⁸).
