description: Current archives of the LAMOST telescope contain millions of pipeline-processed spectra that have probably never been seen by human eyes. Most of the rare objects with interesting physical properties, however, can only be identified by visual analysis of their characteristic spectral features. A proper combination of interactive visualisation with modern machine learning techniques opens new ways to discover such objects. We apply active learning classification supported by deep convolutional networks to automatically identify complex emission-line shapes in multi-million spectra archives. We used the pool-based uncertainty sampling active learning driven by a custom-designed deep convolutional neural network with 12 layers inspired by VGGNet, AlexNet, and ZFNet, but adapted for one-dimensional feature vectors. The unlabelled pool set is represented by 4.1 million spectra from the LAMOST DR2 survey. The initial training of the network was performed on a labelled set of about 13000 spectra obtained in the region around H$α$ by the 2m Perek telescope of the Ondřejov observatory, which mostly contains spectra of Be and related early-type stars. The differences between the Ondřejov intermediate-resolution and the LAMOST low-resolution spectrographs were compensated for by Gaussian blurring. After several iterations, the network was able to successfully identify emission-line stars with an error smaller than 6.5%. Using the technology of the Virtual Observatory to visualise the results, we discovered 1013 spectra of 948 new candidates of emission-line objects in addition to 664 spectra of 549 objects that are listed in SIMBAD and 2644 spectra of 2291 objects identified in an earlier paper of a Chinese group led by Wen Hou. The most interesting objects with unusual spectral properties are discussed in detail.

description: Here, in order to study \textit{stochastic resonance} (SR) in a double-well potential when the noise source has a spectral density of the form $f^{-κ}$ with varying $κ$, we have extended a procedure, introduced by Kaulakys et al (Phys. Rev. E \textbf{70}, 020101 (2004)). In order to have an analytical understanding of the results, we have obtained an effective Markovian approximation, that allows us to make a systematic study of the effect of such kind of noises on the SR phenomenon. The comparison of numerical and analytical results shows an excellent qualitative agreement indicating that the effective Markovian approximation is able to correctly describe the general trends.

description: We discuss some of the preliminary results and findings derived from the analysis of a first sample of flares detected by the XRT on board Swift. The analysis shows that the morphology of flares is the one we expect from the collision of ultra-relativistic shells as it happens during the internal shock model proposed by Rees and Meszaros in 1994. Furthermore the Delta(t)/t ratio and the decay-time to rise-time ratio have mean values that are in good agreement with the values observed in the prompt emission pulses that are believed to originate from internal shocks. The conclusion is that the flare analysis favors the internal shock as due to shells that have been ejected by the central engine after the prompt emission. The central engine seems to remain active and capable of generating large amounts of energy also at later times. More data are needed to establish whether or not some of the flares could be due to shells that have been emitted with small Lorentz factor at the time of the prompt emission and generate later time flares due to the catch up of these shells.

description: Η παρούσα μεταπτυχιακή εργασία διερευνά την προβληματική της αναγνώρισης του δικαιώματος της προσωπικότητας των νομικών προσώπων. Δικαιοπολιτικό της θεμέλιο αποτελεί η ικανότητα δικαίου των συλλογικών μορφωμάτων (άρθρα 61 και 62 του Α.Κ.), η οποία τα αποκλείει από εκείνες μόνον τις έννομες σχέσεις, που απαιτούν ανθρώπινες ιδιότητες (π.χ. οικογενειακές). Τα νομικά πρόσωπα απολαμβάνουν, λοιπόν, ενός γενικού δικαιώματος της προσωπικότητας ως επακόλουθο της κοινωνικής συνεισφοράς τους σε ευρύτατους τομείς της συναλλακτικής ζωής, όπως τον οικονομικό, πολιτικό και επιστημονικό. Ωστόσο, η έκταση αυτού εμφανίζεται περιορισμένη σε σχέση με την αντίστοιχη των φυσικών προσώπων, καθώς στα στοιχεία, που το απαρτίζουν, συγκαταλέγονται σε αδρές γραμμές η επωνυμία, η φήμη και η πίστη, η ταυτότητα, η ελευθερία, το άσυλο της έδρας και η σφαίρα του απορρήτου τους. Για την προστασία του παρέχονται κατά βάση οι αξιώσεις αφενός για άρση της προσβολής και παράλειψη στο μέλλον (άρθρα 57-58 του Α.Κ.) και αφετέρου για ικανοποίηση της ηθικής βλάβης των νομικών προσώπων (άρθρα 59 και 932 του Α.Κ.) με την αιτιολογία ότι η μη υλική ζημία τους συνίσταται στο στιγματισμό της κοινωνικής τους υπόστασης και τη δυσχέρανση εκπλήρωσης της αποστολής τους.
description: The present dissertation examines the issue of recognition of the right of the personality of legal persons. Its legislative foundation is the legal capacity of collective entities (Article 61 and 62 of the Civil Code) which excludes the latter from solely the legal relations requiring human properties (for instance familial ones). Therefore, legal persons enjoy a general right of the personality as being the result of their social contribution in very large domains of the social life, such as the financial, political and scientific. Nevertheless, the extent of this specific right seems to be limited regarding the extent of the right of natural persons, since the components of this right include, generally speaking, their (corporate) name, reputation and faith, identity, freedom, asylum of the headquarter and privacy. As far as its protection is concerned, some claims generally order both the cessation of the infringement (Articles 57-58 of the Civil Code) as well as the moral damage of the legal persons (Articles 59 and 932 of the Civil Code) on the ground that their non-material damage consists in the stigmatisation of their social status and makes the fulfilment of their remit more difficult.

description: We have proposed and implemented a modification of the well-known wall follower algorithm to identify a backbone (a current-carrying part) of the percolation cluster. The advantage of the modified algorithm is identification of the whole backbone without visiting all edges. The algorithm has been applied to backbone identification in networks produced by random deposition of conductive sticks onto an insulating substrate. We have found that (i) for concentrations of sticks above the percolation threshold, the strength of the percolating cluster quickly approaches unity; (ii) simultaneously, the percolation cluster is identical to its backbone plus simplest dead ends, i.e., edges that are incident to vertices of unit degree.

Advances to familiar instrument concepts, such as fiber positioners and deployable fiber-fed IFUs, are discussed along with image relays and deployable active sensors. We conceive deployable payloads as components of systems more traditionally regarded as part of telescope systems rather than instruments - such as adaptive optics and ADCs. Also presented are some of the opportunities offered by the truly unique capabilities of Starbug, such as microtracking to apply intra-field distortion correction during the course of an observation.

description: During the 1960s and 1970s the poetic reception of Karl Marx begins to increase in Germany. In this regard, it can be observed that Hans Magnus Enzensberger’s poetic and essayistic reception of Marx is not only quite complex, but also unorthodox. By focusing on the anthology „Gespräche mit Marx und Engels,“ edited by Enzensberger, his comedy „Der Untergang der Titanic“ and his poem „Karl Heinrich Marx,“ the diverse forms of reference to this philosopher are analyzed. It can be demonstrated that Enzensberger uses the montage technique masterly to avoid one-dimensional confessions.

description: In many data sets, crucial elements co-exist with non-essential ones and noise. For data represented as networks in particular, several methods have been proposed to extract a "network backbone", i.e., the set of most important links. However, the question of how the resulting compressed views of the data can effectively be used has not been tackled. Here we address this issue by putting forward and exploring several systematic procedures to build surrogate data from various kinds of temporal network backbones. In particular, we explore how much information about the original data need to be retained alongside the backbone so that the surrogate data can be used in data-driven numerical simulations of spreading processes. We illustrate our results using empirical temporal networks with a broad variety of structures and properties.

Aρχικά καθορίσαμε την πιθανή θέση που κατείχε το βιβλίο του Ιώβ στη ζωή του λαού ( Sitz im Leben ), δηλαδή τον «ιστορικό τόπο» του κειμένου και τη μελέτη του «πνευματικού κόσμου » μέσα στον οποίο ζει ο συγγραφέας του. Στη συνέχεια εντοπίσαμε λέξεις και έννοιες κλειδιά της βιβλικής αφήγησης και αποπειραθήκαμε να τις συνδέσουμε με τα νεοελληνικά λογοτεχνήματα, με σκοπό την ερμηνεία τους. Τηρουμένων των αναλογιών, έχοντας υπόψη μας τις στάσεις, τις αξίες και την συμπεριφορά κάθε νεοέλληνα συγγραφέως, το ενδιαφέρον εστιάστηκε στο πώς αυτοί αντιλήφθηκαν και χρησιμοποίησαν τις συγκεκριμένες λέξεις, έννοιες και νοήματα σε αντιπαραβολή με το βιβλίο του Ιώβ.

description: The aim of the present study was the trace of any verbal or ideological relevance between the biblical literature, the Old Testament book of Job in particular, and the Modern Greek Literature, the generation of the '30 specifically. Initially we set the possible position the book of Job might have had in the lives of the people (Sitz im Leben), meaning the “historical site” of the passage and the study of the “spiritual world” the writer lives in. Then we went on locating biblical key words tempting to associate them to the Modern Greek work of literature, in order to interpret them. Mutatis mutandis, having in mind attitudes, values and behaviour of every Modern Greek writer, our concern focused on how they realized and used the specific words, concepts and meanings in collation to the book of Job. In conclusion, we reported our findings whether and to what extent Modern Greek writers were influenced by the biblical writer.

description: In this study we investigate a data-driven stochastic methodology to parameterize small-scale features in a prototype multiscale dynamical system, the Lorenz '96 (L96) model. We propose to model the small-scale features using a vector autoregressive process with exogenous variable (VARX), estimated from given sample data. To reduce the number of parameters of the VARX we impose a diagonal structure on its coefficient matrices. We apply the VARX to two different configurations of the 2-layer L96 model, one with common parameter choices giving unimodal invariant probability distributions for the L96 model variables, and one with non-standard parameters giving trimodal distributions. We show through various statistical criteria that the proposed VARX performs very well for the unimodal configuration, while keeping the number of parameters linear in the number of model variables. We also show that the parameterization performs accurately for the very challenging trimodal L96 configuration by allowing for a dense (non-diagonal) VARX covariance matrix.

description: We present Hubble Space Telescope imaging of a pre-explosion counterpart to SN 2019yvr obtained 2.6 years before its explosion as a type Ib supernova (SN Ib). Aligning to a post-explosion Gemini-S/GSAOI image, we demonstrate that there is a single source consistent with being the SN 2019yvr progenitor system, the second SN Ib progenitor candidate after iPTF13bvn. We also analyzed pre-explosion Spitzer/IRAC imaging, but we do not detect any counterparts at the SN location. SN 2019yvr was highly reddened, and comparing its spectra and photometry to those of other, less extinguished SNe Ib we derive $E(B-V)=0.51\substack{+0.27\\-0.16}$ mag for SN 2019yvr. Correcting photometry of the pre-explosion source for dust reddening, we determine that this source is consistent with a $\log(L/L_{\odot}) = 5.3 \pm 0.2$ and $T_{\mathrm{eff}} = 6800\substack{+400\\-200}$ K star. This relatively cool photospheric temperature implies a radius of 320$\substack{+30\\-50} R_{\odot}$, much larger than expectations for SN Ib progenitor stars with trace amounts of hydrogen but in agreement with previously identified SN IIb progenitor systems. The photometry of the system is also consistent with binary star models that undergo common envelope evolution, leading to a primary star hydrogen envelope mass that is mostly depleted but seemingly in conflict with the SN Ib classification of SN 2019yvr. SN 2019yvr had signatures of strong circumstellar interaction in late-time ($>$150 day) spectra and imaging, and so we consider eruptive mass loss and common envelope evolution scenarios that explain the SN Ib spectroscopic class, pre-explosion counterpart, and dense circumstellar material. We also hypothesize that the apparent inflation could be caused by a quasi-photosphere formed in an extended, low-density envelope or circumstellar matter around the primary star.

Αρχικά αναπτύχθηκε το αντικειμενοστραφές μοντέλο ταξινόμησης με τη χρήση δορυφορικής εικόνας Quickbird με σκοπό την χαρτογράφηση των δασών και δασικών εκτάσεων όπως αυτά ορίζονται από την ελληνική νομοθεσία. Κατόπιν, το μοντέλο μεταφέρθηκε σε δορυφορική εικόνα SPOT-5, έγινε έλεγχος της ικανότητας μεταφοράς των αλγορίθμων της ταξινόμησης και δημιουργήθηκε ο χάρτης για την ίδια περιοχή μελέτης. Τα αποτελέσματα κρίνονται θετικά καθώς η ακρίβεια ταξινόμησης των δυο εικόνων ήταν υψηλή. Αυτό αποδεικνύει ότι η χαρτογράφηση των δασών και δασικών εκτάσεων με αντικειμενοστραφή ταξινόμηση εικόνας Quickbird είναι δυνατή, ενώ η μεταφορά του μοντέλου σε δορυφορική εικόνα SPOT-5, της ίδιας περιοχής μελέτης, είναι εφικτή.
description: The aim of the present thesis was the evaluation of the possibility of discrimination of forests and woodlands with digital analysis of satellite data. Initially, an object-oriented classification model was developed using Quickbird satellite imagery, in order to classify forest and woodland areas, according to the Greek legislation. Then, the model was applied at the same area using a SPOT-5 satellite image, the transferability of the object-based model was tested and finally a new map was generated. The classification results revealed a high accuracy in both mapping exercises. This shows that the mapping of forests and woodlands with object classification of a Quickbird image is considered accurate, and the model transferability exercise using a satellite image SPOT-5 was proven equally successful.

description: The design and operation of supply chain networks are characterized as dynamic decision making problems. Despite the number of models that have been developed over time most of them give exclusive emphasis on determining the cost or maximizing the profit while ignoring other types of financial decisions. The objective of this thesis is to develop two different models in general optimal design and operation of supply chain networks while integrating the concepts of the bankruptcy index (z-score) and the sale and leaseback of fixed assets. Their modeling is done using mixed integer linear and nonlinear programming, respectively, through a series of operational and design constraints with time varying demand. The applicability and efficiency of one of the two proposed models is presented through a case study that generates very important conclusions about the structure and function of the underlying supply chain network.

description: There has been significant progress recently in our understanding of the stationary measures of the exclusion process on $Z$. The corresponding situation in higher dimensions remains largely a mystery. In this paper we give necessary and sufficient conditions for a product measure to be stationary for the exclusion process on an arbitrary set, and apply this result to find examples on $Z^d$ and on homogeneous trees in which product measures are stationary even when they are neither homogeneous nor reversible. We then begin the task of narrowing down the possibilities for existence of other stationary measures for the process on $Z^d$. In particular, we study stationary measures that are invariant under translations in all directions orthogonal to a fixed nonzero vector. We then prove a number of convergence results as $t\to\infty$ for the measure of the exclusion process. Under appropriate initial conditions, we show convergence of such measures to the above stationary measures. We also employ hydrodynamics to provide further examples of convergence.

description: This article considers the theme of Karl Marx in the poetry and artwork of Dmitrii Prigov. It conceives of his poetic communication as a political activity, which is stressed by its performative qualities and is presented by the example of the poem “Moscow and Muscovites”. Further on, the article distinguishes four speech attitudes in relation to the term “Karl Max” in the culture of Soviet Russia: belief, condemnation, quotation, and Prigov’s technique of reading Marx’s texts literally. Thus, he interprets Marx’s sentence “The answer to a question is contained in the critique of the question itself” verbatim and, by generalization (a common device of Soviet Marxism), leads it to absurdity. Prigov does the same with the slogan “Proletarians of the World Unite” from the “Communist Manifesto”, which he transforms into a parodic epistolary poem modeled on Lermontov’s “Demon”. The article also considers the use of the name of Marx and the stereotypically connected family names of Engels, Lenin, and Stalin in Prigov’s work and argues, using the motif of the policemen (“militsaner”), that, contrary to Marx’s expectations of real Socialism, the function of power was not dying but growing. Finally, attention is drawn to the role of so-called historical and socio-economical “Marxist laws” (such as ‘dialectical’ and ‘historical materialism’), which in Prigov’s work are dethroned and become possible concepts beside others. Thus, Prigov installs freedom in place of the Marxist necessity of interpretation, which was also the basis of Mikhail Lifshitz’s anti-modernist aesthetics, the most important contribution of Soviet philosophy to aesthetic theory.

The discrete nature of the lattice and quantum phonon effects are fully taken into account. The dependence on phonon frequency, Coulomb repulsion, confinement strength (dot size) and electron-phonon interaction strength is studied over a wide range of parameter values. Confinement is found to reduce the size of (bi-)polarons at a given coupling strength, to reduce the critical coupling for small-(bi-)polaron formation, to increase the polaron binding energy, and to be more important in lower dimensions. The present method also permits to consider models with dispersive phonons, anharmonic confinement, or long-range interactions.

description: Motivated by a recent successful dynamical explanation for the newly observed fully-charm structure $X(6900)$ in the mass spectrum of di-$J/ψ$ by LHCb [J.~Z.~Wang \textit{et al.} arXiv:2008.07430], in this work, we extend the same dynamical rescattering mechanism to predict the line shape of more potential fully-heavy structures in the invariant mass spectrum of $J/ψψ(3686)$, $J/ψψ(3770)$, $ψ(3686) ψ(3686)$, and $J/ψΥ(1S)$ at high energy proton-proton collisions, whose verification in experiments should be helpful to further clarify the nature of $X(6900)$. The above final states of vector heavy quarkonia can be experimentally reconstructed more effectively by a $μ^+μ^-$ pair in the muon detector compared with $Q\bar{Q}$ meson with other quantum numbers. Furthermore, the corresponding peak mass positions of each of predicted fully-heavy structures are also given. Our theoretical studies here could provide some valuable information for the future measurement proposals of LHCb and CMS, especially based on the accumulated data after completing Run III of LHC in the near future.

description: We investigate self-similar solutions of evolution equation of a (1+1)-dimensional field model with the V-shaped potential $U(ϕ) = | ϕ|,$ where $ϕ$ is a real scalar field. The equation contains a nonlinear term of the form $sign(ϕ)$, and it possesses a scaling symmetry. It turns out that there are several families of the self-similar solutions with qualitatively different behaviour. We also discuss a rather interesting example of evolution with non self-similar initial data - the corresponding solution contains a self-similar component.

description: In order to address some fundamental questions in neutrino physics a wide, future programme of neutrino oscillation experiments is currently under discussion. Among those, long baseline experiments will play a crucial role in providing information on the value of theta13, the type of neutrino mass ordering and on the value of the CP-violating phase delta, which enters in 3-neutrino oscillations. Here, we consider a beta-beam setup with an intermediate Lorentz factor gamma=450 and a baseline of 1050 km. This could be achieved in Europe with a beta-beam sourced at CERN to a detector located at the Boulby mine in the United Kingdom. We analyse the physics potential of this setup in detail and study two different exposures (1 x 10^{21} and 5 x 10^{21} ions-kton-years). In both cases, we find that the type of neutrino mass hierarchy could be determined at 99% CL, for all values of delta, for sin^2(2 theta13) > 0.03. In the high-exposure scenario, we find that the value of the CP-violating phase delta could be measured with a 99% CL error of ~20 deg if sin^2 (2 theta13) > 10^{-3}, with some sensitivity down to values of sin^2(2 theta13) ~ 10^{-4}. The ability to determine the octant of theta23 is also studied, and good prospects are found for the high-statistics scenario.

description: In 1993, the Stó:1ō raised a memorial housepost in recognition to the contributions of Stó:lō military veterans at home and abroad. The following year, a second commemorative ceremony was held for Stó:1ō veterans at the war memorial. This thesis describes a portion of these two ceremonies. It examines how recollected knowledge about the past is communicated, and the setting of the commemorations in a personal, social, and cultural context. Research for this thesis is based on oral history interviews with nine Stó:1ō veterans and numerous other family members, participation in the 1994 commemoration, and a review of the literature on Coast Salish ceremonialism and Stó:1ō oral traditions. I argue that Stó:lōcommemorations are a special form of social reciprocity, which involves the coordination of public support for veterans, and the sharing of responsibility to remember the past.

description: Oxygen vacancies are ubiquitous in TiO$_2$ and play key roles in catalysis and magnetism applications.Despite being extensively investigated, the electronic structure of oxygen vacancies in TiO$_2$ remains controversial both experimentally and theoretically.Here we report a study of a neutral oxygen vacancy in TiO$_2$ using state-of-the-art quantum chemical electronic structure methods.We find that the ground state is a color center singlet state in both the rutile and the anatase phase of TiO$_2$. Specifically, embedded CCSD(T) calculations find, for an oxygen vacancy in rutile, that the lowest triplet state energy is 0.6 eV above the singlet state, and in anatase the triplet state energy is higher by 1.4 eV. Our study provides fresh insights on the electronic structure of the oxygen vacancy in TiO$_2$, clarifying earlier controversies and potentially inspiring future studies of defects with correlated wave function theories.
Electron density diagnostic potential of Ar XIV soft X-ray emission lines

description: Theoretical electron density-sensitive line ratios $R_1 - R_6$ of Ar XIV soft X-ray emission lines are presented. We found that these line ratios are sensitive to electron density $n_e$, and the ratio $R_1$ is insensitive to electron temperature $T_e$. Recent work has shown that accurate atomic data, such as electron impact excitation rates, is very important for reliable determination of the electron density of laboratory and astrophysical plasmas. Present work indicates that the maximum discrepancy of line ratios introduced from different atomic data calculated with distorted wave and R-matrix approximations, is up to 18% in the range of $n_e=10^{9-13}$cm$^{-3}$. By comparison of these line ratios with experiment results carried out in electron beam ion trap (EBIT-II), electron density of the laboratory plasma is diagnosed, and a consistent result is obtained from $R_1$, $R_2$ and $R_3$. Our result is in agreement with that diagnosed by Chen et al using triplet of N VI. A relative higher diagnosed electron density from $R_2$ is due to its weak sensitivity to electron temperature. A better consistency at lower $T_e$ indicates that temperature of the laboratory plasma is lower than log$T_e$(K)=6.5. Comparison between the measured and theoretical ratios reveals that 32.014~Åline is weakly blended by lines from other Ar ions, while 30.344~Åline is strongly contaminated.

description: We calculate the nucleon form factors G_A and G_P of the isovector axial-vector current and the pion-nucleon form factor G_piN in manifestly Lorentz-invariant baryon chiral perturbation theory up to and including order O(p^4). In addition to the standard treatment including the nucleon and pions, we also consider the axial-vector meson a_1 as an explicit degree of freedom. This is achieved by using the reformulated infrared renormalization scheme. We find that the inclusion of the axial-vector meson effectively results in one additional low-energy coupling constant that we determine by a fit to the data for G_A. The inclusion of the axial-vector meson results in an improved description of the experimental data for G_A, while the contribution to G_P is small.

Reaffirming cultural identity : a case of stó:lō pithouse reconstruction
Creators: name: Little, Tamara Maureen
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a case study of the building of a Coast Salish dwelling, called a pithouse, in the context of cultural education amongst the Sto:lo people of the Fraser Valley. This thesis, which grew collaboratively out of a fieldschool project initiated by the stó:lō community, explores the literature on cultural revival and education, and suggests descriptive ethnography as a methodology by which one may investigate changing methods of cultural transmission within the stó:lō community. Emic perspectives are highlighted by generously including the words of community members on such topics as the pithouse rebuilding project, formal cultural education, and the relationship between the past and contemporary healing efforts. By presenting this emic perspective, the thesis rebukes the application of anthropological literature based in a salvage paradigm which concentrates on the adjudication of authenticity in Aboriginal cultural revivals. Instead it examines themes and questions which are of interest to Sto:lo community members, particularly the employees of the stó:lō Nation political body which is most responsible for cultural education.

description: For a group $G$, a subgroup $U \leq G$ and a group $\mathrm{Inn}(G) \leq A \leq \mathrm{Aut}(G)$, we say that $U$ is an $A$-covering group of $G$ if $G = \bigcup_{a\in A}U^a$. A theorem of Jordan (1872) implies that if $G$ is a finite group, $A = \mathrm{Inn}(G)$ and $U$ is an $A$-covering group of $G$, then $U = G$. Motivated by a question concerning Kronecker classes of field extensions, Neumann and Praeger (1988) conjectured that, more generally, there is an integer function $f$ such that if $G$ is a finite group and $U$ is an $A$-covering subgroup of $G$, then $|G:U| \leq f(|A:\mathrm{Inn}(G)|)$. A key piece of evidence for this conjecture is a theorem of Praeger (1994), which asserts that there is a two-variable integer function $g$ such that if $G$ is a finite group and $U$ is an $A$-covering subgroup of $G$, then $|G:U|\leq g(|A:\mathrm{Inn}(G)|,c)$ where $c$ is the number of $A$-chief factors of~$G$. Unfortunately, the proof of this result contains an error. In this paper, using a different argument, we give a correct proof of this theorem.
