description: A visual and theatrical exercise anchored in the Grades 11 and 12 Ontario Curriculum for Media Arts and Interdisciplinary Studies was enacted and recorded as individual experiences of each participant. The event was re-mastered in a graphic representation that depicts the forces, pushes and pulls of curriculum and students’ needs which educators experience on a daily basis. Students participating in a co-educational public high school course were photographed alongside their yearbook advisor to examine the methodology of a/r/tography, embodiment and time/space/place during a staged photo shoot session. Participants, including the author, documented their experiences of this research creation event through written and photographic feedback. The basic findings resulted in the creation of the Dimension of the Mind Embodied (DOME), a new theory I coined that builds on Deleuze and Guattari’s (1987) concept of the rhizome. Chaque participant à un programme d'études en arts des médias et études interdisciplinaires de l'Ontario pour les 11e et 12e années a interprété un exercice visuel et théâtral. L'évènement a été remasterisé en une représentation graphique illustrant tant les forces et les mouvements en opposition du programme d'études que les besoins des élèves auxquels font face les enseignants à chaque jour. On a photographié des élèves qui suivaient un cours dans une école secondaire publique mixte à côté d'un conseiller de sorte à étudier l'a/r/tographie, la concrétisation et le temps/l'espace/le lieu pendant une session de photos publique. Les participants, y compris l'auteur, ont documenté leurs expériences relatives à cet évènement de création en produisant de la rétroaction écrite et photographique. De ces résultats a découlé la création de Dimension of the Mind Embodied (DOME), une nouvelle théorie que j'ai inventée à partir du concept de rhizome de Deleuze et Guattari (1987).

description: Super tau-Charm facility(STCF) is a future electron-position collider operating at tau-Charm energy region aimed to study hadron structure and spectroscopy. The baseline design of the STCF barrel particle identification(PID) detector in the momentum range up to 2 GeV/c is provided by a Ring Imaging Cherenkov Counter(RICH). The architecture of the RICH is an approximately focusing design with liquid perfluorohexane sealed in the quartz container as radiator and a hybrid combination of a CsI coated layers of THGEMs and a Micromegas as the photo-electron detector. A 16*16 cm^2 prototype with quartz radiator has been built and tested at DESY. It was stably operated with 10^5 effective gain. In this paper, the design, the performance, the reconstruction algorithm and the systematic error for single photon electron angular resolution in the aspect of RICH detectors are discusses.

description: The first string excited state can be observed as a resonance in dijet invariant mass distributions at the LHC, if the scenario of low-scale string with large extra dimensions is realized. A distinguished property of the dijet resonance by string excited states from that the other "new physics" is that many almost degenerate states with various spin compose a single resonance structure. It is examined that how we can obtain evidences of low-scale string models through the analysis of angular distributions of dijet events at the LHC. Some string resonance states of color singlet can obtain large mass shifts through the open string one-loop effect, or through the mixing with closed string states, and the shape of resonance structure can be distorted. Although the distortion is not very large (10% for the mass squared), it might be able to observe the effect at the LHC, if gluon jets and quark jets could be distinguished in a certain level of efficiency.

description: This work is devoted to the development of a new method for taking into account the roughness of the cathode surface and the study of the temperature distribution and thermal expansion in the cathode part of the gyrotron. A trajectory analysis was performed for the electron-optical system of the SPbPU gyrotron with an operating frequency of 74.2 GHz and an output power of about 100 kW. The calculation results made it possible to determine the influence of roughness of the cathode and thermal effects caused by its heating on the quality of the helical electron beam. The results allowed us to determine the characteristic sizes of inhomogeneities on the cathode surface in the SPbPU gyrotron.
Mathematics Performance and Principal Effectiveness: A Case Study of Some Coastal Primary Schools in Sri Lanka

Publisher: name: Alberta Journal of Educational Research
Year: 2012

description: This mixed method research study is situated in the school effectiveness research paradigm to examine the correlation between the effectiveness of urban, primary school principals and their students’ performance in mathematics. Nine, urban, primary schools from Negombo, a coastal fishing area in Sri Lanka, were selected; their student achievements in mathematics were documented in a longitudinal study from 1998 to 2002. At the end of 2002, principals in these schools were interviewed to obtain evidence of their effectiveness in six areas: (a) school vision, (b) decision-making process, (c) curriculum process, (d) staff development, (e) community relations, and (f) managing changes and challenges. The results indicate a measurable correlation between school performance and principal effectiveness. However, these results should be cautiously interpreted since there are other contextual factors that affect the functioning of these schools. The results also illustrate some challenges faced by principals in their day-to-day activities in coastal, primary schools in Sri Lanka. Cette recherche à méthodes mixtes se situe dans le paradigme de recherche sur l'efficacité scolaire pour examiner la corrélation entre l'efficacité des directeurs d'écoles primaires en milieu urbain et le rendement de leurs élèves en mathématiques. On a choisi neuf écoles primaires en milieu urbain à Negombo, une région du Sri Lanka où se pratique la pêche côtière et où le rendement des élèves en mathématiques avait été documenté dans une étude longitudinale de 1998 à 2002. À la fin 2002, on a passé en entrevue les directeurs de ces écoles pour obtenir des données sur leur efficacité dans six domaines: (a) la vision de l'école, (b) le processus décisionnel, (c) le processus impliquant le programme d'études, (d) le perfectionnement du personnel, (e) les relations avec la communauté et (f) la gestion des changements et des défis. Les résultats indiquent qu'il existe une corrélation mesurable entre le rendement scolaire et l'efficacité du directeur. Toutefois, il faudrait interpréter les résultats avec prudence compte tenu des autres facteurs contextuels qui affectent le fonctionnement de ces écoles. Les résultats illustrent également quelques uns des défis auxquels font face les directeurs au cours de leurs activités quotidiennes dans les écoles primaires de la côte du Sri Lanka.

description: The quasistatic approximation (QSA) is an efficient method of simulating laser- and beam-driven plasma wakefield acceleration, but it becomes imprecise if some plasma particles make long longitudinal excursions in a strongly nonlinear wave, or if waves with non-zero group velocity are present in the plasma, or the plasma density gradients are sharp, or the beam shape changes rapidly. We present an extension to QSA that is free from its limitations and retains its main advantages of speed and reduced dimensionality. The new approach takes into account the exchange of information between adjacent plasma layers. We introduce the physical model, describe its numerical implementation, and compare the simulation results with available analytical solutions and other codes.

Magnetic Flux Expulsion in Star Formation

description: Stars form in dense cores of magnetized molecular clouds. If the magnetic flux threading the cores is dragged into the stars, the stellar field would be orders of magnitude stronger than observed. This well-known "magnetic flux problem" demands that most of the core magnetic flux be decoupled from the matter that enters the star. We carry out the first exploration of what happens to the decoupled magnetic flux in 3D, using an MHD version of the ENZO adaptive mesh refinement code. The field-matter decoupling is achieved through a sink particle treatment, which is needed to follow the protostellar accretion phase of star formation. We find that the accumulation of the decoupled flux near the accreting protostar leads to a magnetic pressure buildup. The high pressure is released anisotropically, along the path of least resistance. It drives a low-density expanding region in which the decoupled magnetic flux is expelled. This decoupling-enabled magnetic structure has never been seen before in 3D MHD simulations of star formation. It generates a strong asymmetry in the protostellar accretion flow, potentially giving a kick to the star. In the presence of an initial core rotation, the structure presents an obstacle to the formation of a rotationally supported disk, in addition to magnetic braking, by acting as a rigid magnetic wall that prevents the rotating gas from completing a full orbit around the central object. We conclude that the decoupled magnetic flux from the stellar matter can strongly affect the protostellar collapse dynamics.

The effect of simulated orthostatic hypotension on cardiac function in experimental spinal cord injury
Creators: name: Hayes, Brian
Publisher: name: University of British Columbia
Year: 2020

description: High thoracic and cervical spinal cord injuries (SCI) are detrimental to autonomic function, increasing cardiovascular disease prevalence and impairing cardiac, cerebrovascular and arterial function. Complete SCI to the third thoracic segment (T3) or higher is known to be detrimental to the structure and intrinsic function of the left ventricle (LV). In addition, injuries to T6 or higher are known to impair the cortically-derived cardiovascular response to postural change, causing episodes of low systemic blood pressure known as orthostatic hypotension (OH) up to 28 times each day. While these frequent episodes of OH following SCI are associated with impairments in cerebrovascular function and an increased risk of coronary artery disease, it is not clear whether there is a direct relationship between OH and cardiac dysfunction following SCI. The purpose of this thesis was, therefore, to examine the impact of regular bouts of OH on cardiac function following SCI. To do so, we developed a preclinical model of OH simulation using lower body negative pressure (LBNP) in a rodent model of experimental SCI. The impact of either sham injury, T3 transection alone or T3 transection with 8 weeks of daily simulated OH on cardiac structure and function was assessed in vivo using pressure-volume catheterization and echocardiography, and ex vivo via histological analysis of myocardial tissue. We found that daily simulation of OH caused an uncoupling of the ventricular-arterial interaction following SCI, indicating a decrease in the efficiency and adaptability of the cardiovascular system that was driven by decreased LV contractile function. Additionally, we found evidence of atrophy and remodeling of cardiomyocytes following SCI and an increase in myocardial collagen following OH simulation in SCI animals. Together, the findings of this thesis imply that frequent occurrence of OH following T3 SCI may accelerate the onset of cardiac dysfunction that follows SCI and subsequently increase the risk of cardiovascular disease. Future clinical investigations are needed to understand whether these differences translate to the bedside, and apply more direct measures of ventricular mechanics and arterial function to provide context to our PV data and drive the development of informed treatment protocols.

description: In any static spacetime the quasi-local Tolman mass contained within a volume can be reduced to a Gauss-like surface integral involving the flux of a suitably defined generalized surface gravity. By introducing some basic thermodynamics and invoking the Unruh effect one can then develop elementary bounds on the quasi-local entropy that are very similar in spirit to the holographic bound, and closely related to entanglement entropy.

description: In the background of a stationary black hole, the "conserved current" of a particular spinor field always approaches the null Killing vector on the horizon. What's more, when the black hole is asymptotically flat and when the coordinate system is asymptotically static, then the same current also approaches the time Killing vector at the spatial infinity. We test these results against various black hole solutions and no exception is found. The spinor field only needs to satisfy a very general and simple constraint.

Active viscoelastic nematics with partial degree of order

Year: 2022
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Continuum models of active nematic gels have proved successful to describe a number of biological systems consisting of a population of rodlike motile subunits in a fluid environment. However, in order to get a thorough understanding of the collective processes underlying the behaviour of active biosystems, the theoretical underpinnings of these models still need to be critically examined. To this end, we derive a minimal model based on a nematic elastomer energy, where the key parameters have a simple physical interpretation and the irreversible nature of activity emerges clearly. The interplay between viscoelastic material response and active dynamics of the microscopic constituents is accounted for by material remodelling. Partial degree of order and defect dynamics is included as a result of the kinematic coupling between the nematic elastomer shape-tensor and the orientational ordering tensor $\bQ$. In a simple one-dimensional channel geometry, we use linear stability analysis to show that even in the isotropic phase the interaction between flow-induced local nematic order and activity results in a spontaneous flow of particles.

description: We define two transformations from term rewriting systems (TRSs) to context-sensitive TRSs in such a way that termination of the target system implies outermost termination of the original system. In the transformation based on 'context extension', each outermost rewrite step is modeled by exactly one step in the transformed system. This transformation turns out to be complete for the class of left-linear TRSs. The second transformation is called `dynamic labeling' and results in smaller sized context-sensitive TRSs. Here each modeled step is adjoined with a small number of auxiliary steps. As a result state-of-the-art termination methods for context-sensitive rewriting become available for proving termination of outermost rewriting. Both transformations have been implemented in Jambox, making it the most successful tool in the category of outermost rewriting of the last edition of the annual termination competition.

description: Computational text phenotyping is the practice of identifying patients with certain disorders and traits from clinical notes. Rare diseases are challenging to be identified due to few cases available for machine learning and the need for data annotation from domain experts. We propose a method using ontologies and weak supervision, with recent pre-trained contextual representations from Bi-directional Transformers (e.g. BERT). The ontology-based framework includes two steps: (i) Text-to-UMLS, extracting phenotypes by contextually linking mentions to concepts in Unified Medical Language System (UMLS), with a Named Entity Recognition and Linking (NER+L) tool, SemEHR, and weak supervision with customised rules and contextual mention representation; (ii) UMLS-to-ORDO, matching UMLS concepts to rare diseases in Orphanet Rare Disease Ontology (ORDO). The weakly supervised approach is proposed to learn a phenotype confirmation model to improve Text-to-UMLS linking, without annotated data from domain experts. We evaluated the approach on three clinical datasets, MIMIC-III discharge summaries, MIMIC-III radiology reports, and NHS Tayside brain imaging reports from two institutions in the US and the UK, with annotations. The improvements in the precision were pronounced (by over 30% to 50% absolute score for Text-to-UMLS linking), with almost no loss of recall compared to the existing NER+L tool, SemEHR. Results on radiology reports from MIMIC-III and NHS Tayside were consistent with the discharge summaries. The overall pipeline processing clinical notes can extract rare disease cases, mostly uncaptured in structured data (manually assigned ICD codes). We discuss the usefulness of the weak supervision approach and propose directions for future studies.

Creators: name: Winkler, John McCauley
Publisher: name: University of British Columbia
Year: 2019

description: Dietary n-6 polyunsaturated fatty acids (n-6 PUFA) like linoleic acid (LA) are linked to inflammatory diseases. It is believed that arachidonic acid (ARA), generated from LA is primarily responsible for such inflammation. However, studies show that dietary LA does not raise ARA in vivo and chronic disease patients often demonstrate low serum ARA. Thus, I hypothesized that LA, the parent n-6 PUFA causes inflammation independent of ARA. First, I show that adding LA activates RAW 264.7 macrophages (MФs) which demonstrates increased mitochondrial respiration, glucose uptake, cholesterol storage and reactive oxygen species (ROS) production compared to oleic acid (OA), a monounsaturated fatty acid (MUFA). Interestingly though, feeding a diet rich in LA (corn oil, CO; 54% LA) or OA (olive oil, OO; 54% OA) for six weeks in mice did not alter the inflammatory state of macrophages (PMФs). However, when I fed these diets to ELOVL5 +/- mice, which were deficient in an enzyme that allows the conversion of LA to ARA and therefore has higher LA, the accumulation of LA in PMФs demonstrated proinflammatory effects. Taken together, I conclude that LA accumulation in the short-term does not activate macrophages but long-term accumulation of LA mediated by congenital ELOVL deficiency does. In addition, feeding a MUFA diet did not counteract the activation of macrophages or higher LA levels in ELOVL5 ⁺/⁻ mice. Thus, I conclude that dietary MUFA cannot overcome a genetic deficiency of ELOVL5, indicating the critical role of this enzyme in maintaining PUFA levels in macrophages. Thus, my thesis clarifies the crucial role of ELOVL5 in the PUFA bioconversion pathway and its central importance in regulating the pro-inflammatory properties of n-6 PUFA. In the current milieu of high LA in our diet, activation of ELOVL5 and clearance of LA could be used as a therapeutic target against inflammation.

description: Gaussian process regression (GPR) has been a well-known machine learning method for various applications such as uncertainty quantifications (UQ). However, GPR is inherently a data-driven method, which requires sufficiently large dataset. If appropriate physics constraints (e.g. expressed in partial differential equations) can be incorporated, the amount of data can be greatly reduced and the accuracy further improved. In this work, we propose a hybrid data driven-physics constrained Gaussian process regression framework. We encode the physics knowledge with Boltzmann-Gibbs distribution and derive our model through maximum likelihood (ML) approach. We apply deep kernel learning method. The proposed model learns from both data and physics constraints through the training of a deep neural network, which serves as part of the covariance function in GPR. The proposed model achieves good results in high-dimensional problem, and correctly propagate the uncertainty, with very limited labelled data provided.

description: We evaluated the cost-effectiveness of Struggling Schools, a user-generated approach to Comprehensive School Reform implemented in 100 low achieving schools serving disadvantaged students in a Canadian province. The results show that while Struggling Schools had a statistically significant positive effect on Grade 3 Reading achievement, d=.48 in 2005-06 and .60 in 2006-07, the program was not cost-effective when compared to two alternatives: 1. The cost of bringing one student to the provincial achievement standard was more than 25% higher in Struggling Schools than in the status quo. 2. The cost-effectiveness ratio (i.e., effect size per $1,000 of incremental cost) was lower in Struggling Schools than in Success For All. Struggling Schools would have been deemed to be cost-effective if different choices had been made, especially in (a) the calculation of costs (e.g., the inclusion of donated time), (b) the decision rules for declaring cost-effectiveness, and (c) the studies used to access comparative data. --- Nous avons évalué le rapport cout-efficacité du programme Struggling Schools (écoles en difficulté), une approche générée par l'utilisateur à la réforme d'ensemble des écoles mise en œuvre dans 100 écoles peu performantes desservant des élèves défavorisés dans une province canadienne. Les résultats indiquent que si l'effet du programme Struggling Schools sur le rendement en lecture en 3e année était statistiquement significatif et positif (d= 0,48 en 2005-06 et 0,60 en 2006-07), son rapport cout-efficacité n'était pas aussi intéressant que celui des deux alternatives suivantes: 1. Le cout de rehausser le rendement d'un élève pour qu'il atteigne le standard provincial était plus élevé de 25% avec Struggling Schools par rapport au statut quo. 2. Le rapport cout-efficacité (c.-à-d. l'effet par 1 000$ de cout différentiel) du programme Struggling Schools était plus bas que celui du programme Success for All. Le programme Struggling Schools aurait été jugé rentable si on avait choisi autrement, notamment par rapport (a) au calcul des couts (par ex. l'inclusion de la main d'œuvre à titre gratuit), (b) aux règlements portant sur les décisions quant aux critères de rentabilité, et (c) aux études employées pour accéder aux données de comparaison.

description: Substance abuse, especially among adolescents, has long been an important issue in society. In light of the adverse impact of substance abuse, scholars, educators, and policy-makers have proposed different approaches to prevent and reduce such abuse. This paper investigates the effectiveness of the two prominent approaches—educational and deterrent—in preventing and reducing adolescent substance abuse. The educational approach (e.g., school-based prevention programming) tends to be more comprehensive and better grounded in theories than the deterrent approach (e.g., drug testing). The educational approach not only targets multiple psychosocial factors contributing to substance abuse, but it is also supported by empirical studies showing that school-based prevention programming is effective in preventing substance abuse and has long-lasting positive influences on adolescent development. Practical implications of implementing school-based prevention programming are also discussed. L'abus d'alcool ou d'autres drogues, surtout chez les adolescents, constitue depuis longtemps une préoccupation importante de la société. À la lumière de l'impact défavorable de cet abus, les chercheurs, enseignants et décideurs ont proposé différentes approches pour le prévenir et le limiter. Cet article porte sur l'efficacité de deux approches importantes, l'une pédagogique, l'autre dissuasive, visant la prévention et la réduction de l'abus d'alcool ou d'autres drogues chez les adolescents. L'approche pédagogique (par ex. les programmes de prévention en milieu scolaire) est, de façon générale, plus globale et mieux fondée sur les théories que l'approche dissuasive (par ex. dépistage des drogues). Non seulement l'approche pédagogique cible-t-elle les divers facteurs psychosociaux qui contribuent à cet abus, elle est de plus appuyée par des études empiriques indiquant que les programmes de prévention en milieu scolaire sont des outils efficaces dans la prévention de l'abus d'alcool ou d'autres drogues et qu'ils ont un impact positif à long terme sur le développement des adolescents. Nous discutons des répercussions pratiques de la mise en œuvre des programmes de prévention en milieu scolaire.

description: Beams can be characterized as structures that are susceptible to a variety of loads and can be either static or dynamic. When dynamic actions are applied, the beams can assume a state of vibration that compromises the entire structural system â being vitally important to understand its dynamic behavior. Therefore the objective of this work is to study the dynamic behavior of a cantilever beam when subjected to external forces of different natures, namely: Simple excitation force f=1 and harmonic force f= 0 that vary with time. The modal analysis were performed, both analytical and numerically ,to find the natural frequencies and mode shapes for transient and harmonic analysis, to finally see how our structure will respond for different applied Loads.

description: We present the first open-source, GPU-based code for complex plasmas. The code, OpenDust, aims to provide researchers both experimenters and theorists user-friendly and high-performance tool for self-consistent calculation forces, acting on microparticles, and microparticles' charges in a plasma flow. OpenDust performance originates from highly-optimized Cuda back-end and allows to perform self-consistent calculation of plasma flow around microparticles in seconds. This code outperforms all available codes for self-consistent complex plasma simulation. Moreover, OpenDust can also be used for simulation of larger systems of dust microparticles, that was unavailable before. OpenDust interface is written in Python, which provides ease-of-use and simple installation from Conda repository.
Questioning the Research on Early Career Teacher Attrition and Retention

description: In this paper, we consider scholarly work on early career teacher attrition, and retention, from 1999 to 2010. Much of the literature has framed attrition as either a problem associated with individual factors (e.g., burnout), or a problem associated with contextual factors (e.g., support and salary). Some recent conceptualizations consider early career teacher attrition as an identity- making process that involves a complex negotiation between individual and contextual factors. On the basis of our review, we suggest the need to shift the conversation from one focused only on retaining teachers, toward a conversation about sustaining teachers. This shift offers the possibility of new insights about teacher education and about the kinds of spaces needed on school landscapes to sustain and retain beginning teachers. Cet article porte sur les travaux académiques évoquant l'attrition et la rétention des enseignants en début de carrière entre 1999 et 2010. Une part importante de la littérature présente l'attrition comme un problème associé à des facteurs individuels (par ex. épuisement professionnel) ou bien à des facteurs contextuels (par ex. appui et salaire). Selon certaines conceptualisations récentes, l'attrition d'enseignants en début de carrière serait un processus de formation identitaire impliquant des négociations complexes entre l'individu et des facteurs contextuels. À partir de notre analyse, nous évoquons le besoin de s'éloigner des conversations portant exclusivement sur le besoin de retenir les enseignants pour discuter plutôt de soutien aux enseignants. D'un tel changement peuvent découler de nouvelles idées sur la formation des enseignants et le type de milieux scolaires nécessaires pour appuyer et retenir les enseignants en début de carrière.

description: Airflow simulation results depend on a good prediction of near wall turbulence. In this paper a comparative study between different near wall treatments is presented. It is applied to two test cases: (1) the first concerns the fully developed plane channel flow (i.e. the flow between two infinitely large plates). Simulation results are compared to direct numerical simulation (DNS) data of Moser et al. (1999) for $Reτ$ = 590 (where $Reτ$ denotes the friction Reynolds number defined by friction velocity $uτ$, kinematics viscosity $v$ and the channel half-width $δ$); (2) the second case is a benchmark test for room air distribution (Nielsen, 1990). Simulation results are compared to experimental data obtained with laser-doppler anemometry. Simulations were performed with the aid of the commercial CFD code Fluent (2005). Near wall treatments available in Fluent were tested: Standard Wall Functions, Non Equilibrium Wall Function and Enhanced Wall Treatment. In each case, suitable meshes with adequate position for the first near-wall node are needed. Results of near-wall mean streamwise velocity U+ and turbulent kinetic energy k+ profiles are presented, variables with the superscript of + are those non dimensional by the wall friction velocity $uτ$ and the kinematic viscosity ν.

description: We point out that in theories where the gravitino mass, $M_{3/2}$, is in the range (10-50)TeV, with soft-breaking scalar masses and trilinear couplings of the same order, there exists a robust region of parameter space where the conditions for electroweak symmetry breaking (EWSB) are satisfied without large imposed cancellations. Compactified string/M-theory with stabilized moduli that satisfy cosmological constraints generically require a gravitino mass greater than about 30 TeV and provide the natural explanation for this phenomenon. We find that even though scalar masses and trilinear couplings (and the soft-breaking $B$ parameter) are of order (10-50)TeV, the Higgs vev takes its expected value and the $μ$ parameter is naturally of order a TeV. The mechanism provides a natural solution to the cosmological moduli and gravitino problems with EWSB.

Based on the analysis of the associative production of mediators and τ -leptons at the energies of the future collider, the possibility of searching in the non-excluded region of the parameter space was found. The obtained sensitivity curves at the 90% C.L. for the mediators mass range below 4 GeV demonstrate the power of the SCTF for light dark matter search.

description: Bipartite entanglement measures are fantastic tools to investigate quantum phases of correlated electrons. Here, I analyze the entanglement spectrum of **gapped** two-leg quantum Heisenberg ladders on a periodic ribbon partitioned into two identical periodic chains. Comparison of various entanglement entropies proposed in the literature is given. The entanglement spectrum is shown to closely reflect the low-energy gapless spectrum of each individual edge, for any sign of the exchange coupling constants. This extends the conjecture initially drawn for Fractional Quantum Hall systems to the field of quantum magnetism, stating a direct correspondence between the low-energy entanglement spectrum of a partitioned system and the true spectrum of the "virtual edges". A mapping of the reduced density matrix to a thermodynamic density matrix is also proposed via the introduction of an effective temperature.
