description: The method of decoy-state quantum key distribution (QKD) requests different intensities of light pulses. Existing theory has assumed exact control of intensities. Here we propose a simple protocol which is secure and efficient even there are errors in intensity control. In our protocol, decoy pulses and signal pulses are generated from the same father pulses with a two-value attenuation. Given the upper bound of fluctuation of the father pulses, our protocol is secure provided that the two-value attenuation is done exactly. We propose to use unbalanced beam-splitters for a stable attenuation. Given that the intensity error is bounded by $\pm5%$, with the same key rate, our method can achieve a secure distance only 1 km shorter than that of an ideal protocol with exactly controlled source.

description: We image semi-flexible polymer networks under shear at the micrometer scale. By tracking embedded probe particles, we determine the local strain field, and directly measure its uniformity, or degree of affineness, on scales of 2-100 micron. The degree of nonaffine strain depends on polymer length and crosslink density, consistent with theoretical predictions. We also find a direct correspondence between the uniformity of the microscale strain and the nonlinear elasticity of the networks in the bulk.

description: We propose a Poincare-invariant description for the effective dynamics of systems of charged particles by means of intrinsic multipole moments. To achieve this goal we study the effective dynamics of such systems within two frameworks -- the particle itself and hydrodynamical one. We give a relativistic-invariant definition for the intrinsic multipole moments both pointlike and extended relativistic objects. Within the hydrodynamical framework we suggest a covariant action functional for a perfect fluid with pressure. In the case of a relativistic charged dust we prove the equivalence of the particle approach to the hydrodynamical one to the problem of radiation reaction for multipoles. As the particular example of a general procedure we obtain the effective model for a neutral system of charged particles with dipole moment.

description: Due to increased lipophilicity, stability, and decreased cytotoxicity in biological systems, ferrocene derivatives are promising building blocks for therapeutic agents. This manuscript reports the binding of N’-ferrocenylmethyl-N’-phenylbenzohydrazide (FhD) with deoxyribonucleic acid (DNA) studied by absorption spectroscopy and cyclic voltammetry. Binding constants and binding free energies for the FhD-DNA complex were measured using these two methods as 5100 M−1, 6109 M−1 and −21.2 kJ/mol, −21.6 kJ/mol, respectively. DFT calculations were also performed and revealed important physical characteristics of the FhD compound. Subsequently, the system was explored by computational molecular docking, confirming a non-covalent mode of binding via minor groove with a binding energy of −25.5 kJ/mol. Furthermore, molecular dynamics of the docked complex of FhD with DNA were carried out for 100 ns followed by MM-GBSA to have a deep understanding of the complex’s dynamic behavior in physiological systems, and to determine the Gibbs free energy which was −14.31 Kcal/mol over a 100 ns window. The results show important antitumor potential of FhD due to its spontaneous non-covalent interaction with DNA and the efficient binding stability of the FhD-DNA complex in a physiological system.

Τα δεδομένα της έρευνας συλλέχθηκαν μέσα από γραπτές παραγωγές των μαθητών από το ΕΣΚΕΙΜΑΘ οι οποίες ψηφιοποιήθηκαν και επισημειώθηκαν ως προς τα λάθη της συμφωνίας. Έτσι εξετάστηκαν οι περιπτώσεις ρηματικής συμφωνίας, ονοματικής συμφωνίας και κλιτικών με το αντικείμενο αναφοράς τους. Τα αποτελέσματα έδειξαν ότι οι μαθητές παρουσιάζουν δυσκολίες με την κατάκτηση της ονοματικής συμφωνίας και των κλιτικών ενώ η ρηματική συμφωνία είναι κατακτημένη. Επίσης η πιο προβληματική κατηγορία εμφανίζεται η κατηγορία του γένους με την πτώση και τον αριθμό να μην φέρουν σημαντικό αριθμό λαθών. Ακόμη, το επίπεδο γλωσσομάθειας φαίνεται πως συνδέεται αναλογικά με τον αριθμό των λαθών, καθώς αυτά μειώνονται στα υψηλότερα επίπεδο. Τέλος, γίνεται μία προσπάθεια σύνδεσης των αποτελεσμάτων με τα θεωρητικά μοντέλα κατάκτησης δεύτερης/ ξένης γλώσσας, όπου αναδεικνύονται προβλήματα μορφολογικής πραγμάτωσης που διαχωρίζουν τους μη φυσικούς ομιλητές από τους φυσικούς
description: This study investigates the acquisition of agreement by Turkish students who are learning Greek as an L2, via learner corpora. The data were collected from students’ written productions of ΕΣΚΕΙΜΑΘ (Greek Learner Corpus, GLC). These data have been digitized and annotated for agreement errors. Thus, verbal agreement, nominal agreement, and agreement in clitics have been examined. The results showed that Turkish students have problems with the acquisition of nominal agreement and clitics, while verbal agreement seems to be acquirable. Also, gender seems to be the most problematic grammatical feature, compared to case and number. Furthermore, there seemed to be a positive correlation between the level of proficiency and the number of errors, since the errors appeared to be diminished as the proficiency level was becoming higher. Finally, the results have been discussed in the light of theoretical models of L2 acquisition. It was shown that there were problems with surface morphology, which discriminate the non native speakers from the native ones

description: We develop a model to establish the interconnection between galaxies and their dark matter halos. We use Principal Component Analysis (PCA) to reduce the dimensionality of both the mass assembly histories of halos/subhalos and the star formation histories of galaxies, and Gradient Boosted Decision Trees (GBDT) to transform halo/subhalo properties into galaxy properties. We use two sets of hydrodynamic simulations to motivate our model architecture and to train the transformation. We then apply the two sets of trained models to dark matter only (DMO) simulations to show that the transformation is reliable and statistically accurate. The model trained by a high-resolution hydrodynamic simulation, or by a set of such simulations implementing the same physics of galaxy formation, can thus be applied to large DMO simulations to make "mock" copies of the hydrodynamic simulation. The model is both flexible and interpretable, which paves the way for future applications in which we will constrain the model using observations at different redshifts simultaneously and explore how galaxies form and evolve in dark matter halos empirically.

Resetting transition is governed by an interplay between thermal and potential energy

Year: 2021
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A dynamical process that takes a random time to complete, e.g., a chemical reaction, may either be accelerated or hindered due to resetting. Tuning system parameters such as temperature, viscosity or concentration, can invert the effect of resetting on the mean completion time of the process, which leads to a resetting transition. Though the resetting transition was recently studied for diffusion in a handful of model potentials, it is yet unknown whether the results follow any universality in terms of well-defined physical parameters. To bridge this gap, we propose a general framework which reveals that the resetting transition is governed by an interplay between thermal and potential energy. This result is illustrated for different classes of potentials that are used to model a wide variety of stochastic processes with numerous applications.

description: We consider the spatially homogeneous Boltzmann equation for inelastic hard spheres, in the framework of so-called constant normal restitution coefficients. We prove the existence of self-similar solutions, and we give pointwise estimates on their tail. We also give general estimates on the tail and the regularity of generic solutions. In particular we prove Haff 's law on the rate of decay of temperature, as well as the algebraic decay of singularities. The proofs are based on the regularity study of a rescaled problem, with the help of the regularity properties of the gain part of the Boltzmann collision integral, well-known in the elastic case, and which are extended here in the context of granular gases.

description: Recently, the inverse electrodynamics model (IEM) was introduced and applied to fined Reissner-Nordström black holes in the context of the general relativity coupled minimally with the nonlinear electrodynamics \cite{1}. The solution consists of both electric and magnetic fields as of the dyonic solutions. Here in this note, we show that the IEM model belongs to a more general class of nonlinear electrodynamics with $T=T_{μ}^{μ}=0$. Here $T_{μ}^{ν}$ is the energy-momentum tensor of the nonlinear electrodynamic Lagrangian. Naturally, such a dyonic RN black hole solution is the solution for this general class.

Students’ conceptions of mathematics, and their conceptions of learning, knowing, and self in mathematics
Creators: name: Lacroix, Lionel N.
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the conceptions of mathematics, and conceptions of learning, knowing, and self in mathematics held by two typical students in an intact Algebra 12 class. Their learning of logarithms served as the context for this study. The students' various conceptions were largely integrated, and while there were some differences in the views which made up their conceptions, there were many similarities. These included their views that: mathematics was a set of truths, handed down to them by their teachers, in the form of rules and procedures to get answers for the questions encountered in class; knowing and learning in mathematics were undifferentiated from that in other subjects at school, the memorization of unrelated facts; it was the teacher's job to make learning easy for students by presenting new material slowly and in a step-by-step manner; students played a passive role in the learning process; and they "understood" mathematics when they got the right answers for the questions encountered in class. Furthermore, the students lacked confidence in themselves in mathematics and believed that their learning and success depended upon factors which were largely beyond their control. The following conclusions were drawn from this analysis: students' views on the nature of mathematics and on learning and knowing mathematics influence the kind of mathematics knowledge that they construct by shaping the goals that they set for themselves in the process of learning mathematics, profound but subtle failures in communication which hamper students' learning can occur between teachers and students in the mathematics classroom, students' views can play a major role in limiting or enhancing students' participation within the mathematics classroom and therefore their opportunities for learning and success, students may have unresolved conflicts amongst their views which may be a detriment to their learning, and students may hold views about knowing and learning which they constructed in contexts outside of the mathematics classroom and which are inappropriate for learning mathematics. Fundamental changes are needed in mathematics programming and teaching to address students' conceptions relating to mathematics, and mathematics learning and knowing so that their command of mathematics can be improved.

description: In modeling sequences of data, in order to predict the future, a useful tool are Markov Processes. Markov Processes are used in a wide spectrum of mathematics, whereas the previous state of an event. includes the information of the past, evenmore, the current status has all the information to predict the immidiate future. This paper focuses in the occasion where instead of a single Markov Chain, we have a number of chains (n), where there is a connection of the background mechanism that produces them. So estimation methods are described, where in the system of the n-multiple Markov chains, each chain contributes to the evolution information for the others. In this paper we collected weather data, and there is a comparison between the prediction results of the MultiVariate Markov model and the corresponding simple Markov chains

description: Using archival Chandra observations of 19 LINERs we explore the X-ray properties of their inner kiloparsec to determine the origin of their nuclear X-ray emission, to investigate the presence of an AGN, and to identify the power source of the optical emission lines. The relative numbers of LINER types in our sample are similar to those in optical spectroscopic surveys. We find that diffuse, thermal emission is very common and is concentrated within the central few hundred parsec. The average spectra of the hot gas in spirals and ellipticals are very similar to those of normal galaxies. They can be fitted with a thermal plasma (kT~0.5 keV) plus a power law (photon index of 1.3-1.5) model. There are on average 3 detected point sources in their inner kiloparsec with L(0.5-10 keV)~10^37-10^40 erg/s. The average cumulative luminosity functions for sources in spirals and ellipticals are identical to those of normal galaxies. In the innermost circle of 2.5" radius in each galaxy we find an AGN in 12 of the 19 galaxies. The AGNs contribute a median of 60% of the 0.5-10 keV luminosity of the central 2.5" region, they have luminosities of 10^37-10^39 erg/s (Eddington ratios 10^-8 to 10^-5). The ionizing luminosity of the AGNs is not enough to power the observed optical emission lines in this particular sample. Thus, we suggest that the lines are powered either by the mechanical interaction of an AGN jet (or wind) with the circumnuclear gas, or by stellar processes, e.g. photoionization by post-AGB stars or young stars.

description: We present the results of high resolution spectroscopy of the prototype polar AM Herculis observed with Chandra High Energy Transmission Grating. The X-ray spectrum contains hydrogen-like and helium-like lines of Fe, S, Si, Mg, Ne and O with several Fe L-shell emission lines. The forbidden lines in the spectrum are generally weak whereas the hydrogen-like lines are stronger suggesting that emission from a multi-temperature, collisionally ionized plasma dominates. The helium-like line flux ratios yield a plasma temperature of 2 MK and a plasma density 1 - 9 x10^12 cm^-3, whereas the line flux ratio of Fe XXVI to Fe XXV gives an ionization temperature of 12.4 +1.1 -1.4 keV. We present the differential emission measure distribution of AM Her whose shape is consistent with the volume emission measure obtained by multi-temperature APEC model. The multi-temperature plasma model fit to the average X-ray spectrum indicates the mass of the white dwarf to be ~1.15 M_sun. From phase resolved spectroscopy, we find the line centers of Mg XII, S XVI, resonance line of Fe XXV, and Fe XXVI emission modulated by a few hundred to 1000 km/s from the theoretically expected values indicating bulk motion of ionized matter in the accretion column of AM Her. The observed velocities of Fe XXVI ions are close to the expected shock velocity for a 0.6 M_sun white dwarf. The observed velocity modulation is consistent with that expected from a single pole accreting binary system.

In the tradition of Sarvamnaya, knowledge is not just information, it is a way of being. An Acharya's life is interpersonal, experiential, and deeply integrated with their wisdom. A student does not merely listen; they learn through mimicry, through observing, absorbing, and aligning themselves with the Acharya's way of being. This is how wisdom is passed down—not as abstract theory, but as lived reality.

description: Over the last few years of the heyday of hybrid halide perovskites, so many metal cations additives have been tested to improve their optoelectronic properties that it is already difficult to find an element that has not yet been tried. In general, the variety of these approaches is united under the name "doping", however, there is currently no clear understanding of the mechanisms of the influence of the metal ion additives on the properties of the lead halide perovskite materials. For many ions there is even no consensus on the most fundamental questions: what lattice position does a given ion occupy and is it incorporated in the structure at all? Here, we derived a system of effective radii of different metal ions in the iodine environment for the set of iodide compounds and reveal their crystal chemical role in the APbI3 perovskites. We analysed the possible lattice positions for 40 most common monovalent, divalent, and trivalent metals to reveal whether they could successfully enter into the perovskite structures. We show that, at most, three parameters - effective size, electronegativity and the softness of metal ions are the main ones for crystal chemical analysis of the possibility of metal doping of hybrid halide perovskites. Our results provide a useful theoretical guidance to rationalize and improve current doping strategies of hybrid halide perovskites with metal ions.

description: In(III)-A3B-type porphyrins containing para-phenylenediamine (p-PDA) as an axial moiety have been efficiently synthesized and characterized spectroscopically to procure the structures of the synthesized complexes. The axial coordination of the amine moiety with In(III) porphyrins brings about a modest shift in the 1H NMR signals and the electronic absorptions in CH3OH, CH3COCH3, CHCl3, and CH3COOC2H5 reflect the hyperchromicity of p-PDA-In(III) porphyrins in comparison to non-ligated metal chelates. All the synthesized macrocyclic porphyrins have negative solvatochromism with the blue shift in the electronic absorption spectra in more polar solvents like CH3OH than those in the less polar CHCl3 as solvent. The photoluminescence spectra show maximum excitonic peaks at 623, 620, and 615 nm for p-phenylenediamine-In(III)-5,10,15-trikis(p-methylphenyl)-20-(p-nitrophenyl)porphyrin [p-PDA-In-tPP1], p-phenylenediamine-In(III)-5,10,15-trikis(p-methoxyphenyl)-20-(p-nitrophenyl)porphyrin [p-PDA-In-tPP2] and p-phenylenediamine-In(III)-5,10,15-trikis(p-dimethylaminophenyl)-20-(p-nitrophenyl)porphyrin [p-PDA-In-tPP3], respectively, which confirmed that the In(III) porphyrins are considered to be sitting atop (SAT) or out of the plane (OOP) type complexes. Further, the stability of the complexes was determined through thermogravimetric analysis, and the structural evolutions through different phases of the synthesized porphyrins were deduced from the powder X-ray diffraction. To get more insight into the molecular structures and their complexes, we carried out the quantum mechanical calculations using DFT-based dispersion which showed that from OH− to p-PDA substitution, the BDE energies drop considerably.

For this goal, we gathered the most important research data and the entire theoretical framework in order to develop the phonological deficits in a more comprehensive and detailed way. Of particular research interest are the findings of transparent and less transparent language systems in the expression of dyslexia

description: We have fabricated a lateral double barrier magnetic tunnel junction (MTJ) which consists of a single self-assembled InAs quantum dot (QD) with ferromagnetic Co leads. The MTJ shows clear hysteretic tunnel magnetoresistance (TMR) effect, which is evidence for spin transport through a single semiconductor QD. The TMR ratio and the curve shapes are varied by changing the gate voltage.

description: The growth of crystal surfaces, under non-equilibrium conditions, involves the displacement of mono-atomic steps by atom diffusion and atom incorporations into steps. The time-evolution of the growing crystal surface is thus governed by a free boundary value problem [known as the Burton--Cabrera--Franck model]. In the presence of an asymmetry of the kinetic coefficients [Erlich--Schwoebel barriers], ruling the rates of incorporation of atoms at each step, it has been shown that a train of straight steps is unstable to two dimensional transverse perturbations. This instability is now known as the Bales-Zangwill instability (meandering instability). We study the non-linear evolution of the step meandering instability that occurs on a crystalline vicinal surface under growth, in the absence of evaporation, in the limit of a weak asymmetry of atom incorporation at the steps. We derive a nonlinear amplitude equation displaying spatiotemporal coarsening. We characterize the self-similar solutions of this equation.

description: Class management is frequently cited as a major concern of teachers, administrators and parents. Yet, despite these concerns, it has only been in the last decade that research on class management has taken a central role in the field of research on effective teaching. In the elementary school, teachers often have the responsibility of managing their classes in physical education and the general dassroom. The purpose of this study was to describe and compare three teachers’ class management practices in the classroom setting and physical education setting at the start of the school year. Three elementary teachers participated in this study. Using a qualitative case study design, data were collected primarily through observations recorded in detailed field notes and audiotaped interviews. A total of 26 physical education sessions and 34 classroom sessions were observed during the first seven weeks of the 1992 school year. The data were inductively analysed using a method of constant comparison. The dass management practices that emerged were twenty-nine management strategies and six class management themes. The class management strategies were divided into three classifications: preventative, guidance and consequence. Teaching episodes of transitions, direct instruction! demonstration, discussion and task work were also identified. The results indicated that teachers used similar types of strategies and themes in both physical education and in the classroom. Twenty-eight of the 29 strategies were found in both settings. Similarities were also found in the emphasis teachers placed on class management practices. In both settings, over 90% of the strategies used were prevenatative and/or guidance, 8 of the top 10 strategies were the same; and the rate strategies were used was highest during teaching episodes of transition and direct instruction and lowest during task work. Differences were found in the emphasis teachers placed in class management practices. Forty - seven percent more strategies were used in physical education than in the classroom; and safety guidelines, ‘withitness’ and ‘overlapping’ were emphasised more in physical education. It may be that the learning environment in physical education, with its physical movement, space and sound level differences affected the emphasis teachers placed on class management. The type of teaching episodes used in the classroom and physical education may also explain the differences in class management practices. This study has implications for teacher education programmes, class management research and general understanding of class management.

description: Presentations of smooth symmetry groups of differentiable stacks are studied within the framework of the weak 2-category of Lie groupoids, smooth principal bibundles, and smooth biequivariant maps. It is shown that principality of bibundles is a categorical property which is sufficient and necessary for the existence of products. Stacky Lie groups are defined as group objects in this weak 2-category. Introducing a graphic notation, it is shown that for every stacky Lie monoid there is a natural morphism, called the preinverse, which is a Morita equivalence if and only if the monoid is a stacky Lie group. As example we describe explicitly the stacky Lie group structure of the irrational Kronecker foliation of the torus.

description: Σκοπός της παρούσας έρευνας ήταν να εξετάσει τις άμεσες επιδράσεις ενός συνδυαστικού πρωτοκόλλου πλειομετρίας με παθητική διάταση στη μυϊκή απόδοση, στις μυϊκές και τενόντιες ιδιότητες της μυοτενόντιας μονάδας, καθώς και στην ηλεκτρομυογραφική δραστηριότητα του έσω, έξω γαστροκνημίου μυός, και του πρόσθιου κνημιαίου μυός σε 17 άτομα. Η μέγιστη ισομετρική ροπή καταγράφηκε με ένα δυναμόμετρο Humac Norm με ταυτόχρονη καταγραφή της ηλεκτρομυογραφικής δραστηριότητας του γαστροκνημίου και του πρόσθιου κνημιαίου μυός, την ανάλυση της κίνησης του ποδιού και με την απεικόνιση με υπέρηχο της μυοτενόντιας σύζευξης. Αξιολογήθηκε η ενεργητική και παθητική δοκιμασία πριν, ενδοιάμεσα, αμέσως μετά και μετά από 1 και 2 λεπτά από την εφαρμογή του πρωτοκόλλου. Τα αποτελέσματα της έρευνας έδειξαν μείωση στη δύναμη, την παθητική ροπή αντίστασης, στο RFD και στην δυσκαμψία του τένοντα, αλλά αύξηση της ηλεκτρομυογραφικής δραστηριότητας του έσω, έξω γαστροκνημίου μυός και της μυϊκής δυσκαμψίας, και προτείνουν την αποφυγή του συνδυαστικού πρωτοκόλλου πλειομετρίας με παθητική διάταση αν σκοπός είναι η βελτίωση της απόδοσης
description: The purpose of this study was to examine the acute effects of a combined plyometric and passive stretching protocol in muscular performance, on musculotendinous properties of muscle-tendon unit, as well as electromyographic activity of medial gastrocnemius, lateral gastrocnemius, and tibialis anterior in 17 individuals. The maximum isometric torque was recorded with a Humac Norm dynamometer with simultaneous recording of electromyographic activity of gastrocnemius and tibialis anterior, motion analysis of foot and ultrasound imaging of musculotendinous junction. The active and passive test was evaluated before, intravenously, immediately after and after 1 and 2 minutes after the protocol was completed. The results of the study showed a decrease in strength, passive resistance momentum, RFD and tendon stiffness, but an increase in electromyographic activity of the medial gastrocnemius, lateral gastrocnemius and muscle stiffness, and suggest avoidance of the combined plyometric and passive stretching protocol if the aim is to improve performance

description: We employed a dual strategy that combines experimental and computational analyses of two copper(II) coordination complexes with σ-donating acylpyrazolone ligands. HLIIIB, [Cu(HLIIIB)2] and [Cu(HLI)2] have been characterized using a variety of physicochemical methods and density functional theory (DFT) calculations using the B3LYP level of theory and 6-31 G basis set. Single crystal X-ray diffraction studies revealed monoclinic and triclinic crystal systems for [Cu(HLI)2] and [Cu(HLIIIB)2], respectively, with square planar geometries for both complexes. Both complexes exhibit quasi-reversible behavior in their cyclic voltammograms in DMSO. ESR spectroscopy was performed to determine the magnetic behaviorof the two complexes. The intermolecular interactions of the complexes were further investigated using Hirshfeld surface analysis. The compounds showed promising cytotoxicities when tested against cancer cell lines of lung carcinoma, hepatocellular carcinoma, and neuroblastoma. Notable apoptotic cell death was observed with [Cu(HLI)2], supported by gene expression changes, indicating induction of apoptosis. The findings suggest the potential of copper complexes as effective agents against neuroblastoma and highlight their superiority to cisplatin.

description: In reacting flow systems, thermoacoustic instability characterized by high amplitude pressure fluctuations, is driven by a positive coupling between the unsteady heat release rate and the acoustic field of the combustor. When the underlying flow is turbulent, as a control parameter of the system is varied and the system approach thermoacoustic instability, the acoustic pressure oscillations synchronize with heat release rate oscillations. Consequently, during the onset of thermoacoustic instability in turbulent combustors, the system dynamics transition from chaotic oscillations to periodic oscillations via a state of intermittency. Thermoacoustic systems are traditionally modeled by coupling the model for the unsteady heat source and the acoustic subsystem, each estimated independently. The response of the unsteady heat source, the flame, to acoustic fluctuations are characterized by introducing external unsteady forcing. This necessitates a powerful excitation module to obtain the nonlinear response of the flame to acoustic perturbations. Instead of characterizing individual subsystems, we introduce a neural ordinary differential equation (neural ODE) framework to model the thermoacoustic system as a whole. The neural ODE model for the thermoacoustic system uses time series of the heat release rate and the pressure fluctuations, measured simultaneously without introducing any external perturbations, to model their coupled interaction. Further, we use the parameters of neural ODE to define an anomaly measure that represents the proximity of system dynamics to limit cycle oscillations and thus provide an early warning signal for the onset of thermoacoustic instability.

description: The collective behavior of the SL(2,R) covariant brane states of non-critical c=1 string theory found in a previous work, is studied in the Fermi liquid approximation. It is found that such states mimick the coset WZW model, whereas only by further restrictions one recovers the double-scaling limit which was purported to be equivalent to closed string models. Another limit is proposed, inspired by the tachyon condensation ideas, where the spectrum is the same of two-dimensional string theory. We close by noting some strange connections between vacuum states of the theory in their different interpretations.
