description: We analyse the tidal disruption probability of potential neutron star--black hole (NSBH) merger gravitational wave (GW) events, including GW190426_152155, GW190814, GW200105_162426 and GW200115_042309, detected during the third observing run of the LIGO/Virgo Collaboration, and the detectability of kilonova emission in connection with these events. The posterior distributions of GW190814 and GW200105_162426 show that they must be plunging events and hence no kilonova signal is expected from these events. With the stiffest NS equation of state allowed by the constraint of GW170817 taken into account, the probability that GW190426_152155 and GW200115_042309 can make tidal disruption is $\sim24\%$ and $\sim3\%$, respectively. However, the predicted kilonova brightness is too faint to be detected for present follow-up search campaigns, which explains the lack of electromagnetic (EM) counterpart detection after triggers of these GW events. Based on the best constrained population synthesis simulation results, we find that disrupted events account for only $\lesssim20\%$ of cosmological NSBH mergers since most of the primary BHs could have low spins. The associated kilonovae for those disrupted events are still difficult to be discovered by LSST after GW triggers in the future, because of their low brightness and larger distances. For future GW-triggered multi-messenger observations, potential short-duration gamma-ray bursts and afterglows are more probable EM counterparts of NSBH GW events.

description: Based on dilatonic dark energy model, we consider two cases: dilaton field with positive kinetic energy(coupled quintessence) and with negative kinetic energy(phantom). In the two cases, we investigate the existence of attractor solutions which correspond to an equation of state parameter $ω=-1$ and a cosmic density parameter $Ω_σ=1$. We find that the coupled term between matter and dilaton can't affect the existence of attractor solutions. In the Mexican hat potential, the attractor behaviors, the evolution of state parameter $ω$ and cosmic density parameter $Ω$, are shown mathematically. Finally, we show the effect of coupling term on the evolution of $X(\fracσ{σ_0})$ and $Y(\frac{\dotσ}{σ^2_0})$ with respect to $N(lna)$ numerically.

description: We propose to learn a generative model via entropy interpolation with a Schrödinger Bridge. The generative learning task can be formulated as interpolating between a reference distribution and a target distribution based on the Kullback-Leibler divergence. At the population level, this entropy interpolation is characterized via an SDE on $[0,1]$ with a time-varying drift term. At the sample level, we derive our Schrödinger Bridge algorithm by plugging the drift term estimated by a deep score estimator and a deep density ratio estimator into the Euler-Maruyama method. Under some mild smoothness assumptions of the target distribution, we prove the consistency of both the score estimator and the density ratio estimator, and then establish the consistency of the proposed Schrödinger Bridge approach. Our theoretical results guarantee that the distribution learned by our approach converges to the target distribution. Experimental results on multimodal synthetic data and benchmark data support our theoretical findings and indicate that the generative model via Schrödinger Bridge is comparable with state-of-the-art GANs, suggesting a new formulation of generative learning. We demonstrate its usefulness in image interpolation and image inpainting.

description: Ο κύριος σκοπός της παρούσας μελέτης είναι να διερευνήσει την αποτελεσματικότητα της υιοθέτησης τόσο έμμεσων όσο και άμεσων στρατηγικών στη διδασκαλία του λεξιλογίου αγγλικών (στα πλαίσια της διδασκαλίας των Αγγλικών ως ξένη γλώσσα) για μαθητές του δημοτικού, μέσα από το φιλικό προς τα παιδιά περιβάλλον της αφήγησης ιστοριών. Για να γίνει αυτό, χρησιμοποιήθηκε ως διδακτικό υλικό ένα λογοτεχνικό βιβλίο διαβαθμισμένης δυσκολίας από το οποίο επιλέχθηκαν 40 λεξιλογικά στοιχεία-στόχοι: 20 διδάχθηκαν άμεσα και 20 έμμεσα, αναλογικά κατανεμημένα ανάλογα με το επίπεδο δυσκολίας και το μέρος του λόγου στο οποίο ανήκαν. Μετά την ολοκλήρωση της ιστορίας, τα παιδιά κλήθηκαν να ανακαλέσουν αυτά τα λεξιλογικά στοιχεία προφορικά. Οι απαντήσεις τους εξετάστηκαν προσεκτικά σε σχέση με τον τρόπο διδασκαλίας και τα ειδικά χαρακτηριστικά των λεξιλογικών στοιχείων, σε μια προσπάθεια να ρίξoυν φως στους παράγοντες που πραγματικά επηρεάζουν την εκμάθηση λεξιλογίου. Τα συλλεχθέντα δεδομένα αναλύθηκαν χρησιμοποιώντας λογισμικό SPSS. Ενδιαφέρον παρουσιάζει το γεγονός ότι παρόλο που τα αποτελέσματα έδειξαν ένα ελαφρώς υψηλότερο λεξιλογικό κέρδος στα στοιχεία που διδάχτηκαν άμεσα, ο παράγοντας ‘άμεση/έμμεση διδασκαλία’ έπαιξε σημαντικό ρόλο μόνο στην ανάκληση των λέξεων που ανήκουν στο επίπεδο Α1. Η συζήτηση των ευρημάτων στηρίζεται σε μια ποικιλία θεωρητικών απόψεων και προτείνει πιθανές κατευθύνσεις για αποτελεσματική εκμάθηση λεξιλογίου
description: The main purpose of this study is to investigate the effectiveness of employing both implicit and explicit strategies in EFL vocabulary instruction for primary school students, through the child-friendly context of storytelling. In so doing, a graded reader was used as the teaching material from which 40 target vocabulary items were selected: 20 were taught explicitly and 20 implicitly, proportionally distributed according to their level of difficulty and the part of speech they belonged to. Upon completion of the story, the children were required to recall the target vocabulary items orally. Their responses were carefully examined in relation to the way of instruction and the special features of the vocabulary items, in an effort to shed light to the factors that actually influence vocabulary learning. The collected data were analyzed using SPSS software. Interestingly, the results showed that despite a slightly higher vocabulary gain in the explicitly taught items, the explicit/implicit factor played an important role only in the recall of the words belonging to A1 level. The discussion of the findings draws on a variety of theoretical perspectives and suggests possible directions for effective vocabulary learning

description: We analyze the transport properties of a Luttinger liquid with an imbedded impurity of explicitly time-dependent strength. We employ a radiative boundary condition formalism to describe the coupling to the voltage sources. Assuming the impurity time dependence to be oscillatory we present a full analytic perturbative result in impurity strength for arbitrary interaction parameter calculated with help of Coulomb gas expansion (CGE). Moreover, a full analytic solution beyond the above restriction is possible for a special non-trivial interaction strength which has been achieved independently by full resummation of CGE series as well as via refermionization technique. The resulting nonlinear current-voltage characteristic turns out to be very rich due to the presence of the additional energy scale associated with the impurity oscillation frequency. In accordance with the previous studies we also find an enhancement of the linear conductance of the wire to values above the unitary limit G0 = 2e2/h.

description: In the current thesis material goods are approached as social action bodies, which react constantly with human beings. The thesis focuses on secondhand clothes, separating between commodities and gifts. The choice of secondhand clothes is associated with the powerful symbolisms involved in these clothes, symbolisms about social status of the people in Greek society, as well as with the approaches to cleanness. Τhis thesis attempts to answer questions about the social meaning of secondhand clothes in particular contexts, to examine the factors that determine their social and economic value, and to interpret the social relations grown and reproduced around these clothes

description: Consider the following mechanism for the random evolution of a distribution of mass on the integer lattice ${\mathbf{Z}}$. At unit rate, independently for each site, the mass at the site is split into two parts by choosing a random proportion distributed according to some specified probability measure on $[0,1]$ and dividing the mass in that proportion. One part then moves to each of the two adjacent sites. This paper considers a continuous analogue of this evolution, which may be described by means of a stochastic flow of kernels, the theory of which was developed by Le Jan and Raimond. One of their results is that such a flow is characterized by specifying its $N$ point motions, which form a consistent family of Brownian motions. This means for each dimension $N$ we have a diffusion in ${\mathbf{R}}^N$, whose $N$ coordinates are all Brownian motions. Any $M$ coordinates taken from the $N$-dimensional process are distributed as the $M$-dimensional process in the family. Moreover, in this setting, the only interactions between coordinates are local: when coordinates differ in value they evolve independently of each other. In this paper we explain how such multidimensional diffusions may be constructed and characterized via martingale problems.

description: The holographic dark energy model is an attempt for probing the nature of dark energy within the framework of quantum gravity. The dimensionless parameter $c$ determines the main property of the holographic dark energy. With the choice of $c\geq 1$, the holographic dark energy can be described completely by a quintessence scalar field. In this paper, we show this quintessential description of the holographic dark energy with $c\geq 1$ and reconstruct the potential of the quintessence as well as the dynamics of the scalar field.

description: In this work, we have analytically analyzed the insulator/superconductor phase transition in the presence of a 5-dimensional $AdS$ soliton background using matching method and thermodynamic geometry approach. We have first employed the matching method to obtain the critical chemical potential. We then move on to investigate the free energy and thermodynamic geometry of this model in 3+1 dimensions. This investigation of the thermodynamic geometry leads to the critical chemical potential of the system from the condition of the divergence of the scalar curvature. We have then compared the value of the critical chemical potential $μ_{c}$ in dimension $d=5$ obtained from these two different methods, namely, the matching method and the thermodynamic geometry procedure. We have also obtained an expression for the condensation operator using the matching method. Our findings agree very well with the numerical findings in the literature.

Modular inflation and the curvaton

Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

subject: FOS: Physical sciences

description: Supersymmetric Peccei-Quinn models which provide a suitable candidate for the curvaton field are studied. These models also solve the mu problem, while generating the Peccei-Quinn scale dynamically. The curvaton is a pseudo Nambu-Goldstone boson corresponding to an angular degree of freedom orthogonal to the axion. Its order parameter increases substantially following a phase transition during inflation. This results in a drastic amplification of the curvaton perturbations. Consequently, these models are able to accommodate low-scale inflation with Hubble parameter at the TeV scale such as modular inflation. We find that modular inflation with the orthogonal axion as curvaton can indeed account for the observations for natural values of the parameters. In particular, the spectral index can easily be made adequately lower than unity in accord with the recent data.

description: The chiral Abelian Higgs model contains an interesting class of solitons found by Rubakov and Tavkhelidze. These objects carry non-zero fermion number $N_F$ (or Chern-Simons number $N_{CS}$, what is the same because of the chiral anomaly) and are stable for sufficiently large $N_F$. In this paper we study the properties of these anomalous solitons. We find that their energy-versus-fermion-number ratio is given by $E\sim N_{CS}^{3/4}$ or $E\sim N_{CS}^{2/3}$ depending on the structure of the scalar potential. For the former case we demonstrate that there is a lower bound on the soliton energy, which reads $E\geq c N_{CS}^{3/4}$, where $c$ is some parameter expressed through the masses and coupling constants of the theory. We construct the anomalous solitons numerically accounting both for Higgs and gauge dynamics and show that they are not spherically symmetric. The thin wall approximation valid for macroscopic solutions with $N_{CS} \gg 1$ is discussed as well.

The role of religion in transformation: its implication for counselling
Creators: name: Khorasani Mansoor, Mitra
Publisher: name: University of British Columbia
Year: 2009

description: A multiple case study approach was used to understand the patterns of transformation from a state of meaninglessness to one of meaningfulness. The informants of this study were three Canadian who were members of the Baha’i faith: one female and two males, from diverse cultural backgrounds. The in-depth interviews were subsequently written down in narrative accounts of their transformation experiences. These narrative accounts were validated by each informant. Common themes across the accounts were identified and as a final report these themes were synthesized into a general story. The common themes portrayed their movement from meaninglessness and purposelessness to meaningfulness and purposefulness. A meaningful purpose in life gave rise to the informants’ sense of agency in life. The common themes, among other things, emphasized the importance of friendship and belief in God in the transformation experience.

description: We introduce Bilby-MCMC, a Markov-Chain Monte-Carlo sampling algorithm tuned for the analysis of gravitational waves from merging compact objects. Bilby-MCMC provides a parallel-tempered ensemble Metropolis-Hastings sampler with access to a block-updating proposal library including problem-specific and machine learning proposals. We demonstrate that learning proposals can produce over a 10-fold improvement in efficiency by reducing the autocorrelation time. Using a variety of standard and problem-specific tests, we validate the ability of the Bilby-MCMC sampler to produce independent posterior samples and estimate the Bayesian evidence. Compared to the widely-used dynesty nested sampling algorithm, Bilby-MCMC is less efficient in producing independent posterior samples and less accurate in its estimation of the evidence. However, we find that posterior samples drawn from the Bilby-MCMC sampler are more robust: never failing to pass our validation tests. Meanwhile, the dynesty sampler fails the difficult-to-sample Rosenbrock likelihood test, over constraining the posterior. For CBC problems, this highlights the importance of cross-sampler comparisons to ensure results are robust to sampling error. Finally, Bilby-MCMC can be embarrassingly and asynchronously parallelised making it highly suitable for reducing the analysis wall-time using a High Throughput Computing environment. Bilby-MCMC may be a useful tool for the rapid and robust analysis of gravitational-wave signals during the advanced detector era and we expect it to have utility throughout astrophysics.

We exploit the strong nonresonant background signal for amplification of the weak backscattered resonant CARS signal by using a homodyne detection scheme. This facilitates a simple, highly sensitive single-beam spectroscopic technique, with a potential for hazardous materials standoff detection applications.

description: It has been controversial whether $η_b$ can be discovered in Tevatron Run 2 through the decay $η_b\to J/ψJ/ψ$ followed by $J/ψ\to μ^+μ^-$. We clear this controversy by an explicit calculation which predicts ${\rm Br}[η_b\to J/ψJ/ψ]$ to be of order $10^{-8}$. It is concluded that observing eta_b through this decay mode in Tevatron Run 2 is rather unrealistic. The eta_b may be observed in the forthcoming LHC experiments through the 4-lepton channel, if the background events can be significantly reduced by imposing some kinematical cuts. By some rough but plausible considerations, we find that the analogous decay processes eta_b to VV, D^*\bar{D}^* also have very suppressed branching ratios, nevertheless it may be worth looking for η_b at LHC and Super B factory through the decay modes η_b \to K_S K^{\pm}π^{\mp}, D^*\bar{D}.

description: The present dissertation is an effort to completely describe the use of the Hidden Markov Model in speech recognition programs. Basic knowledge of stochastic theory is needed whilst the Hidden Markov Model is presented thoroughly. The human speech model is described at first part and the anatomy of message transmission via the spoken language. As structural material Markov Chains are used to build the Hidden Markov Model theory and find the connection between speech recognition and Hidden Markov Model. Going deeper to HMMs, Forward algorithm, Viterbi algorithm and Baum-Welch algorithm are examined as filtering and preprocessing tools. Since the vocabulary of spoken languages is represented as graph, optimization algorithms are used to easily take advantage of it. Beam search and the Token Algorithm are applied to the trellis of the soundwaves to be recognized. In the final part, HTK toolkit, the most significant open source project went over and presented.
description: Η χρήση Κρυφών Μαρκοβιανών Μοντέλων στα λογισμικά αναγνώρισης λόγου αποτελεί ένα από τα σημαντικότερα και πιο σύγχρονα εργαλεία και χρησιμοποιούνται ευρέως τις τελευταίες δεκαετίες. Η ιδέα έγκειται στη μετατροπή της κυματομορφής του προς αναγνώριση λόγου, σε δίκτυο του οποίου οι κόμβοι αναπαριστούν τους φθόγγους που χρησιμοποιούνται από το εκάστοτε αλφάβητο και οι ακολουθίες φθόγγων σχηματίζουν τις λέξεις οι οποίες αποτελούν το μεταδιδόμενο μήνυμα. Εισάγεται η πιθανότητα εμφάνισης ενός φθόγγου έπειτα από έναν άλλον βάσει τις ιδιαιτερότητας κάθε γλώσσας. Οι αρχικές τιμές των πιθανοτήτων αυτών αποδίδονται τυχαία και στη συνέχεια εκτελείται εκπαίδευση του προγράμματος. Έχοντας εισάγει την έννοια της πιθανότητας, ο πίνακας γειτνίασης του γράφου είναι στοχαστικός. Για εξοικονόμηση υπολογιστικής ισχύος και χρόνου, χρησιμοποιούνται τεχνικές φιλτραρίσματος όπως ο αλγόριθμος Viterbi. Έπειτα, μέθοδοι βελτιστοποίησης εφαρμόζονται όπως ο αλγόριθμος Token Passing και ο Beam Search. Στο τελευταίο κομμάτι της εργασίας μελετάται το ευρέως χρησιμοποιούμενο πρόγραμμα γραμμένο σε γλώσσα προγραμματισμού C, το HTK TOOLKIT.

description: Η παρούσα έρευνα ασχολείται με την ομάδα των μεταναστών 1.5 γενιάς στην Ελλάδα. Χρησιμοποιώντας τη μέθοδο της Ερμηνευτικής Φαινομενολογικής Ανάλυσης, προσπαθεί να διερευνήσει σημαντικά ζητήματα της ζωής των παιδιών των μεταναστών, που είναι αυτά της διαμόρφωσης εθνοτικής ταυτότητας και προσαρμογής στη χώρα, του κινήτρου για εκ νέου μετανάστευση ή για επιστροφή στη χώρα καταγωγής, των εμπειριών και απόψεων γύρω από τη νομική κατοχύρωσή τους στην Ελλάδα, αλλά και της ζωής τους στην Ελλάδα της οικονομικής κρίσης. Τα αποτελέσματα της έρευνας, βασιζόμενα στην ανάλυση συνεντεύξεων εννέα ατόμων, οργανώνονται γύρω από τέσσερις μεγάλες θεματικές ενότητες, και αφορούν τα παραπάνω ζητήματα προς διερεύνηση, αλλά και ζητήματα προσαρμογής κατά τη μετάβασή τους στη χώρα, τρόπους που αναπαριστούν την Ελλάδα μέσα από τις εμπειρίες τους με τη νομιμοποίηση, και σκέψεις γύρω από τη χώρα καταγωγής τους. Επίσης παρουσιάζονται οι απόψεις τους για τα αίτια και την αλλαγή τόσο του νομοθετικού πλαισίου για τους μετανάστες στην Ελλάδα, όσο και για την οικονομική κρίση. Εγείρονται προβληματισμοί που αφορούν την προσαρμογή των παιδιών των μεταναστών και την επιλογή της εθνοτικής ταυτότητας, την καταπάτηση βασικών δικαιωμάτων τους, και την αδυναμία της ελληνικής κοινωνίας να υιοθετήσει ένα πολυπολιτισμικό πρόσωπο.
description: The main purpose of this research paper is to investigate the one and a half generation immigrants in Greece. Using the method of Interpretative Phenomenological Analysis, it explores major concerns of the lives of immigrants’ offspring, which are these of their ethnic identity formation and adaptation to the country, their motivation to migrate or return to their country of origin, their experiences and opinions on their legal recognition in Greece as well as their lives in Greece in the years of financial crisis. The results of this survey are based on the analysis of the interviews of nine individuals. These interviews deal with four great modules and they study the aforementioned issues as well as issues about their adaptation when they settled, the way they see Greece through their experience regarding their regularization and their thoughts about their countries of origin. Moreover, this paper shows their opinion on the causes and the changes on the comprehensive body of legislation about immigrants in Greece in addition to financial crisis. There are concerns raised about their adaptation and their choice of ethnic identity, the violation of their basic rights and the weakness of Greek society to adopt a multicultural perspective.

The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak

description: This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving $D_2^+$ and possibly $D^-$ play an important role as sinks of energy (through hydrogenic radiation as well as dissociation) and particles during divertor detachment if low target temperatures ($< 3$ eV) are achieved. Both molecular activated recombination (MAR) and ion source reduction due to a power limitation effect are shown to be important in reducing the ion target flux during a density ramp. In contrast, the electron-ion recombination (EIR) ion sink is too small to play an important role in reducing the ion target flux. MAR or EIR do not occur during $N_2$ seeding induced detachment as the target temperatures are not sufficiently low. The impact of $D_2^+$ is shown to be underestimated in present (vibrationally unresolved) SOLPS-ITER simulations, which could result from an underestimated $D_2 + D^+ \rightarrow D_2^+ + D$ rate. The converged SOLPS-ITER simulations are post-processed with alternative reaction rates, resulting in considerable contributions of $D_2^+$ to particle and power losses as well as dissociation below the $D_2$ dissociation area. Those findings are in quantitative agreement with the experimental results.

description: We review the theory that predicts that the decay constant of the excited light pseudo-scalar mesons are suppressed in the chiral limit relative to the pion decay constant. We compute the decay constant of the first excited pion ($π^\prime$) using unquenched QCD at a fixed lattice spacing with sea quarks of mass as low as a third the mass of the strange quark. The final result is very sensitive to the improvement conditions. We obtain $f_{π^\prime} / f_π$ = 0.078(93) in the chiral limit.

description: Many effective field theories describing gravity cannot arise from an underlying theory based on Riemann geometry or its extensions to include torsion and nonmetricity but may instead emerge from another geometry or may have a nongeometric basis. The Lagrange density for a broad class of such theories is investigated. The action for fermions coupled to gravity is linearized about a Minkowski background and is found to include terms describing small deviations from Lorentz invariance and gravitational gauge invariance. The corresponding nonrelativistic hamiltonian is derived at second order in the fermion momentum. The implications for laboratory experiments and astrophysical observations with fermions are studied, with primary focus on anomalous spin-gravity couplings. First constraints on some coefficients are extracted from existing data obtained via measurements at different potentials, comparisons of gravitational accelerations, interferometric methods, and investigations of gravitational bound states. Some prospects for future experimental studies are discussed.

description: Σκοπός της εργασίας “Οντοθεολογία: η Μεταφυσική του Θεού στη Νεότερη Φιλοσοφία” ήταν να παρουσιαστεί η έννοια του Θεού στην νεότερη φιλοσοφική σκέψη. Πιο συγκεκριμένα μελετήθηκαν δύο φιλόσοφοι, οι οποίοι μιλούν για το Θεό μέσα στα πλαίσια του δικού τους φιλοσοφικού συστήματος. Ο πρώτος ήταν ο Μπαρούχ Σπινόζα και ο δεύτερος ο Γκότφριντ Βίλχελμ Λάιμπνιτς. Έγιναν αναφορές σε βιβλία που έγραψαν οι δυο αυτοί φιλόσοφοι. Από την μελέτη αυτή συνοπτικά προέκυψε ότι ο Θεός στον Σπινόζα είναι ένας και μοναδικός, ότι υπάρχει κατά αναγκαιότητα και πράττει από την αναγκαιότητα της ίδιας του της φύσης. Επίσης οτιδήποτε είναι σε αυτό τον κόσμο εξαρτάται από Αυτόν και δεν είναι δυνατόν να συλληφθεί αλλά και να υπάρξει κάτι δίχως του. Είναι ελεύθερο αίτιο όλων των πραγμάτων και όλα είναι προκαθορισμένα από τον Θεό, τουτέστιν από την ατέλειωτη δύναμή Του. Από την άλλη ο Θεός στον Λάιμπνιτς είναι μια αρμονική δύναμη που διέπει το σύμπαν, είναι μοναδικός και τέλειος. Μέσα από τη δύναμή του προέρχονται τα πάντα όπως η νόηση και η βούληση. Τίνει να προκαλεί όσο το δυνατόν περισσότερο καλό, γιατί έχει και τη γνώση και τη δύναμη για κάτι τέτοιο. Όταν επιτρέπει την αμαρτία το κάνει για την απόκτηση σοφίας.
description: The aim of the present project : “Theology of the supreme being : Metaphysics of God in recent philosophy” was the essence of God in recent philosophical thinking to be presented. Particularly two philosophers were studied, who speak about God within their own philosophical system. The first one was Baruch Spinoza and the second Gottfried Wihelm Leibniz. There were reports in books that these two philosophers wrote. From this study was shortly resulted that God according to Spinoza was one and only, that exists necessarily and he acts from the necessity of his own nature. Also whatever exists in this world depends on him and it is not possible to conceive something or even exist in His absence. He is the unrestrained reason of all things and everything is predefined from God, that is from His endless power. On the other hand God according to Leibniz is a harmonic force that rules the universe, he is unique and perfect. Everything is through his mighty power as is mental perception and will. He tends to cause as much good as possible, because he possesses the knowledge and power for such a thing. When he allows for sin to happen he does so to acquire wisedom.

description: A simple model for simulating tug of war game as varying the player number in a team is discussed to identify the slow pace of fast change. This model shows that a large number of information sources leads slow change for the system. Also, we introduce an opinion diffusion model including the effect of a high degree of clustering. This model shows that the de facto standard and lock-in effect, well-known phenomena in economics and business management, can be explained by the network clusters.
