description: This rigorous review synthesises evidence on education in the conflict-affected contexts of Myanmar. Applying the ERICC conceptual framework (Kim et al., 2022), we analyse the status of education and overall outcomes in terms of access, quality, continuity and coherence of education, particularly in regions that are controlled by ethnic armed organisations (EAOs), in refugee camps and in migrant settings on the Thai-Myanmar border. 114 studies were coded against the ERICC conceptual framework to prioritise key themes at policy systems and local levels. The study found that grievances among the ethnic minority communities because of the exclusionary and hegemonic education policies adopted by the central government have contributed to the formations of diverse ethnic educational provisions that assert autonomy and serve as a vehicle for political resistance. Nevertheless, there is a significant gap in knowledge about the quality of these provisions and the extent to which they promote equity, justice and social cohesion. The 2021 coup has significantly affected all education systems in Myanmar, leading to an acute schooling and learning crisis for millions of children. Most ethnic education systems remain at risk of attack while many are regularly experiencing disruptions due to ongoing clashes between EAOs and the Myanmar military in their regions. Even though some EAOs and ethnic minority communities have historically campaigned for a federal democratic political settlement, there is evidence of ambivalence among key ethnic stakeholders with regards to the Federal Democracy Education Policy proposed by the National Unity Government. Thailand’s restrictive policies towards refugees limits the opportunities open to refugee youth and prohibits them from seeking employment educational opportunities outside the nine refugee camps on the border. This lack of future prospects undermines refugee children’s motivation to continue education. Even though the education in refugee camps is managed by refugee organisations, their reliance on limited and precarious donor funding means that the sustainability and overall quality of the provisions are perpetually at risk. The migrant educational provisions operate within a ‘zone of exception,’ meaning they are generally tolerated by the Thai state but do not receive any governmental support. As a result, migrant learning centres largely operate with external funding. This study highlights serious gaps in education research and calls for policy-relevant and actionable research evidence that could inform educational decision-making in the conflict-affected contexts of Myanmar.

description: The question why the solar corona is much hotter than the visible solar surface still puzzles solar researchers. Most theories of the coronal heating involve a tight coupling between the coronal magnetic field and the associated thermal structure. This coupling is based on two facts: (i) the magnetic field is the main source of the energy in the corona and (ii) the heat transfer preferentially happens along the magnetic field, while is suppressed across it. However, most of the information about the coronal heating is derived from analysis of EUV or soft X-ray emissions, which are not explicitly sensitive to the magnetic field. This paper employs another electromagnetic channel -- the sunspot-associated microwave gyroresonant emission, which is explicitly sensitive to both the magnetic field and thermal plasma. We use nonlinear force-free field reconstructions of the magnetic skeleton dressed with a thermal structure as prescribed by a field-aligned hydrodynamics to constrain the coronal heating model. We demonstrate that the microwave gyroresonant emission is extraordinarily sensitive to details of the coronal heating. We infer heating model parameters consistent with observations.

description: No abstracts are to be cited without prior reference to the author. European hake is a main target fish for the fleet operating in Atlantic waters, although there are many biological unknowns that compromise the quality of the current assessment and scientific advice. Growth, natural mortality and reproduction are main biological processes required to develop population dynamic models for assessment purposes. Currently, the parameters defining these processes such Von Bertalanffy asymptotic length, M, L 50% of maturity or Beverton-Holt steepness are estimated outside the model and set as constants. Population dynamic bayesian models provide a suitable platform to develop solutions to this kind of problems since Bayesian models allow using additional knowledge from similar species in the form of the priors. Informative priors for biological key parameters have been developed based on available data for Northern hake combined with information from other hake species all over the world. This information is analyzed on the light of ecological theory for life history invariants (LHI) to produce the required priors. LHI figures are relatively constant among similar species. Information from other hakes may help to fill the gap in assessment and management of European hake. The pros and cons of using these informative priors to improve hake assessment are finally discussed.

description: Corruption nowadays remains one of the biggest challenges for all societies, including European societies. My thesis starts with a holistic presentation of the social phenomenon called corruption. Then, it is presented the International and European penal legal instruments for the fight against corruption, and then the thesis focuses on the crimes of bribery in the public sector and judicial bribery as laid down in the Greek Penal Code, which represent the central criminal mechanism for the prevention of corruption. We analyze all the special elements of the crimes of passive and energetic public official’s bribery and the different aspects of these crimes (e.g. attempt, participation, concurrence, punishment, confiscation). Then, the thesis analyzes the elements of the crimes of passive and energetic judge’s bribery, which form the core of corruption in the field of justice. My thesis ends with the presentation of measures for the prevention of corruption and de lege ferenda recommendations for the modification of the Greek Penal Code’s provisions for public official’s bribery and judge’s bribery.

description: We predict the existence of a three dimensional quantum Hall effect plateau in a graphite crystal subject to a magnetic field. The plateau has a Hall conductivity quantized at $\frac{4e^2}{\hbar} \frac{1}{c_0} $ with $c_0$ the c-axis lattice constant. We analyze the three-dimensional Hofstadter problem of a realistic tight-binding Hamiltonian for graphite, find the gaps in the spectrum, and estimate the critical value of the magnetic field above which the Hall plateau appears. When the Fermi level is in the bulk Landau gap, Hall transport occurs through the appearance of chiral surface states. We estimate the magnetic field necessary for the appearance of the three dimensional quantum Hall Effect to be $15.4 $T for electron carriers and $7.0 $T for hole carriers.

description: Einstein's theory of General Relativity was proposed over 100 years ago and has successfully passed a large number of observational tests in weak gravitational fields. On the contrary, the strong field regime is still largely unexplored. Astrophysical black holes are ideal laboratories for testing gravity in the strong field regime. Here I will briefly review the current efforts of my group to test the strong gravitational field around black holes using X-ray data from NuSTAR, RXTE, Suzaku, and XMM-Newton.

description: We report results from shell model studies of muon capture on $^{40}$Ca to low-lying levels of $^{40}$K. We discuss the comparison between calculated capture rates, measured capture rates and analogous transitions in ($e$,$e^{\prime}$) scattering in terms of the particle-hole structure of the $^{40}$Ca-$^{40}$K nuclei. We highlight the $^{40}$Ca$(0^+, 0)$$\to$$^{40}$K$(0^-, 2626)$ axial charge transition and its sensitivity to the induced pseudoscalar coupling $g_p$ of the proton's weak interaction. In addition, we address the hindrance of unique first-forbidden transitions due to particle-hole interactions and the emergence of allowed Gamow-Teller transitions due to ground state correlations. Lastly, we examine the longitudinal alignment of $^{40}$K recoils following muon capture, and discuss this possibility for independently determining the induced coupling $g_p$.

description: No abstracts are to be cited without prior reference to the author. Policy makers are mandated to consider whole-ecosystem approaches to decision-making in fisheries management, but community models are rarely used operationally. One barrier to their uptake is the perception that the uncertainties associated with these models are too great for them to be credible in this context. Here we address an important component of this uncertainty, that due to the choice of model parameters, in a rigorous manner, using a size-spectrum model of the North Sea fish community. We find a high degree of uncertainty in projections of community metrics in response to fishing the community at “maximum sustainable yield” (MSY), and wide variations in stock biomasses of individual fish species. However, if we restrict the analysis to combinations of parameters that are both plausible and consistent with ICES stock data, these uncertainties are greatly narrowed. We show how this uncertainty analysis can inform model development. Finally we apply our model ensemble in an uncertainty analysis of the impact of different levels of fishing on the community, and we show how this approach might help with risk-based decision-making.
On the theory of Bose-Einstein condensation of quasiparticles: on the possibility of condensation of magnons at high temperatures

description: Bose condensation of quasiparticles in physical systems of finite size iz considered for the case of ferromagnetic thin films. It is shown that in accordance with present-day experimental capabilities which permit one to achieve densities of long-wave spin excitation of 1018-1019 cm-3, in such films the formation of condensate of such quasiparticles begins at temperatures T~100 K (room one including). It is found that Bose condensation is accompanied by scaling phenomenon according to which the main thermodynamic variable is not the number N of particles but the ratio N/T. This indicates that condensation of magnons can be observed at relatively low magnon densities. The roles played by the shape of the spectrum and film thickness are analyzed.

description: No abstracts are to be cited without prior reference to the author. Bayesian networks (BNs) are often praised on their easy to update -characteristic. This is commonly understood as either updating the conditional probability tables when new data or knowledge appears or updating our prior knowledge by setting some of the variables to a 'known' state. In addition to that, BNs are relatively easy to update in a sense that the structures can be modified to answer different research questions. In many cases, selected nodes and their defined mutual dependencies can be detached from the original model and linked to another BN as such. It is also possible to integrate whole BNs as submodels to larger entities – metamodels, which are useful e.g. for policy analysis where alternative management actions affecting different parts of the system should be evaluated and compared. We present a process of building a cross-disciplinary BN for minimizing the ecosystem risks caused by the increasing oil transport in the Gulf of Finland (GoF), North-Eastern Baltic Sea. This integrative metamodel enables searching for the best management actions in the light of current knowledge and uncertainties.

description: We present in detail and validate an effective Monte Carlo approach for the calculation of the nuclear vibrational densities via integration of molecular eigenfunctions that we have preliminary employed to calculate the densities of the ground and the excited OH stretch vibrational states in protonated glycine molecule [C. Aieta et. al. Nat. Commun. 11, 4348 (2020)]. Here, we first validate and discuss in detail the features of the method on a benchmark water molecule. Then, we apply it to calculate on-the-fly the ab initio anharmonic nuclear densities in correspondence of the fundamental transitions of NH and CH stretches in protonated glycine. We show how we can gain both qualitative and quantitative physical insight by inspection of different one-nucleus densities and assign a character to spectroscopic absorption peaks using the expansion of vibrational states in terms of harmonic basis functions. The visualization of the nuclear vibrations in a purely quantum picture allows us to observe and quantify the effects of anharmonicity on the molecular structure, and to exploit the effect of IR excitations on specific bonds or functional groups, beyond the harmonic approximation. We also calculate the quantum probability distribution of bond-lengths, angles and dihedrals of the molecule. Notably, we observe how in the case of one type of fundamental NH stretching the typical harmonic nodal pattern is absent in the anharmonic distribution.

description: Η μελέτη είναι μια προσπάθεια προσέγγισης της διάσπασης του ΚΚΕ στα 1989. Γενική επιδίωξη αποτελεί η ανάδειξη μερικών πτυχών που οδήγησαν στη διάσπαση καθώς μια συνολική εκτίμηση καθίσταται εκ προοιμίου επισφαλής διαδικασία. Μέσα από τα σημαντικότερα ιστορικά και πολιτικά γεγονότα επιχειρείται να αναδειχθούν η πορεία προς την διαφωνία και τα κυριότερα ιδεολογικά ζητήματα που αποτέλεσαν σημεία προστριβής. Η διεθνής συγκυρία προβάλλεται ως κύριο ερμηνευτικό πλαίσιο στο οποίο εντάσσονται τα γεγονότα. Παράλληλα, δίνεται βαρύτητα στην εθνική ιδιαιτερότητα στο βαθμό που αυτή αλληλεπιδρά με την διεθνή κατάσταση. Για την περίπτωση της διαφωνίας που αναπτύχθηκε στους κόλπους του ΚΚΕ επιδιώκεται η παρακολούθηση εκείνων των κομβικών σημείων που επηρέασαν την διαδρομή από το δεύτερο μισό ως τα τέλη της δεκαετίας του ’80. Η εκλογική απήχηση και η δυναμική στο εργατικό κίνημα μελετώνται ξεχωριστά. Η θέση του ΚΚΕ στο πολιτικό πλέγμα και η σχέση του με τους άλλους κομματικούς φορείς εξετάζονται ώστε να κατανοηθούν τα κριτήρια που διαμόρφωναν την πολιτική τακτική του. Συνολικά εκτιμώνται οι παράγοντες που επέδρασαν στην χάραξη της στρατηγικής και της τακτικής του ως δομικά συστατικά της φυσιογνωμίας του πολιτικού φορέα.
description: This study is an attempt to approach the division of the Greek Communist Party in 1989. An overall assessment made in advance is a precarious process for this reason the general objective is to mark out some aspects that led to the division. Through the most important historical and political events there is an attempt to highlight the way to the dispute and the main ideological issues that have been chafing points. The international situation is highlighted as the main interpretive context surrounding the events. Moreover, there is an emphasis to national particularity insofar as it interacts with the international situation. In the event of the dispute developed within the Communist Party the main goal is to monitor those nodes that have affected the way from the second half of the decade until the end of the 80’s. The electoral impact and dynamics in the labor movement are studied separately. The position of the Greek Communist Party in the political network and its relation with the other party bodies are examined in order to understand the criteria that shape the political tactics. Totally there is an estimation of the factors which influenced the formulation of strategy and tactics as building blocks of character of the political party.

description: The explanatory meeting between the Article 12 of the Constitution and the Article 11 of European Convention of Human Rights, under the auspices of national and European court decisions, considered on the right of combination of members of minority groups, constitute an opportunity to investigate the right of combination and the channels of communication between the two jurisdictions in this study. In an attempt to outline the methodology of national and European courts this thesis identifies both the different perception of the concept of public order by the two courts and also the meaning of the clause of a democratic society, as a control factor for the European Court of Human Rights. Finally, this thesis approaches the issue of piecemeal integration of case-law of judgments of the European Court of Human Rights into national law, which results in limiting the protective scope of the right and highlight the need to understand the European public order of human rights as a new source of law towards better protection of human rights.

description: Seventeen NTDs prioritized by WHO are endemic in 149 countries and affect more than 1.4 billion people globally, which costs these developing economies billions of dollars annually. Chagas disease is one of these NTDs caused by the eurkaryotic parasite Trypanosoma cruzi. The current clinical and preclinical pipeline for T. cruzi is extremely sparse and lacks drug target diversity. Several whole-cell, phenotypic high throughput screens have been completed for T. cruzi, including a screen of over 300,000 molecules in the search for chemical probes. We have compiled and curated relevant biological and chemical compound screening data including (i) compounds and biological activity data from the literature, (ii) high throughput screening datasets, and (iii) predicted metabolites of T. cruzi metabolic pathways. This information was used to help us identify compounds and their potential targets. We have constructed a Pathway Genome Data Base for T. cruzi. In addition we developed Bayesian machine learning models that were used to virtually screen libraries of compounds. 97 compounds were selected for in vitro testing and 11 of these were found to have EC50 < 10uM. We progressed five compounds to an in vivo mouse efficacy model and validated that the machine learning model could identify in vitro active compounds not in the training set as well as known positive controls. One molecule appeared to possess 85.2% efficacy in the mouse model. We have also proposed potential targets (for future verification) for this compound based on structural similarity to known compounds with targets in T. cruzi. The approach we have taken is broadly applicable to mining all the NTDs and we propose how this might be achieved.

description: No abstracts are to be cited without prior reference to the author. This paper presents a state-space modeling framework for the purposes of stock assessment. The approach consists of a core population dynamics model and user definable biological functions and observation models. The stochastic population dynamics builds on the notion of correlated survival and capture events among individuals. The correlation is thought to arise as a combination of schooling behavior, a spatially patchy environment and common but unobserved environmental factors affecting all the individuals. The model can be tailored to each case by choosing appropriate models for the biological processes. Uncertainty about the model parameters and about the appropriate model structures is then described using prior distributions. Different combinations of, for example, age, size, phenotype, life-stage, species and spatial location can be used to structure the population. In order to update the prior knowledge, the model can be fitted to data by defining appropriate observation models. Much like the biological parameters, the observation models must also be tailored to fit each individual case. Currently the modeling framework is implemented using JAGS software, which provides automated MCMC sampling for almost any acyclic Bayesian model.

description: Current statistics of an antidot in the fractional quantum Hall regime is studied for Laughlin's series. The chiral Luttinger liquid picture of edge states with a renormalized interaction exponent $g$ is adopted. Several peculiar features are found in the sequential tunneling regime. On one side, current displays negative differential conductance and double-peak structures when $g<1$. On the other side, universal sub-poissonian transport regimes are identified through an analysis of higher current moments. A comparison between Fano factor and skewness is proposed in order to clearly distinguish the charge of the carriers, regardless of possible non-universal interaction renormalizations. Super-poissonian statistics is obtained in the shot limit for $g<1$, and plasmonic effects due to the finite-size antidot are tracked.

description: The main objective of this particular diplomatic thesis statement is the analysis of the notion of leasing, with particular focus on the construction-structural companies. In reality, the leasing contracts became part of the legislation and operate in our country for more than 20 years, the same way that most developed countries in the United States of America, Europe and Asia also do. In the beginning, it starts with an explanation of the theory of leasing, its main characteristics and forms, the advantages and disadvantages of such a contract are explained and analyzed, Greek legislative framework, leasing companies and finally with the procedure needed or the contract to be made and agreed. On the second part of the paper are presented an analysis of the property market, legal framework and taxation, the documentation required for the leasing contract and the documents required in case of property and also some questions and answers related to the implementation and financing of leasing. On the final part there is an analysis of the benefits offered by leasing companies in the construction industry, 5 years accounts are controlled for a sample of building-construction companies in connection with the lease, the main results are presented on graphs and export the key conclusions of the work.

description: In a continuum model of the solvation of charged molecules in an aqueous solvent, the classical Poisson-Boltzmann (PB) theory is generalized to include the solute point charges and the dielectric boundary that separates the high-dielectric solvent from the low-dielectric solutes. With such a setting, we construct an effective electrostatic free-energy functional of ionic concentrations, where the solute point charges are regularized by a reaction field. We prove that such a functional admits a unique minimizer in a class of admissible ionic concentrations and that the corresponding electrostatic potential is the unique solution to the boundary-value problem of the dielectric-boundary PB equation. The negative first variation of this minimum free energy with respect to variations of the dielectric boundary defines the normal component of the dielectric boundary force. Together with the solute-solvent interfacial tension and van der Waals interaction forces, such boundary force drives an underlying charged molecular system to a stable equilibrium, as described by a variational implicit-solvent model. We develop an $L^2$-theory for the continuity and differentiability of solutions to elliptic interface problems with respect to boundary variations, and derive an explicit formula of the dielectric boundary force. With a continuum description, our result of the dielectric boundary force confirms a molecular-level prediction that the electrostatic force points from the high-dielectric and polarizable aqueous solvent to the charged molecules. Our method of analysis is general as it does not rely on any variational principles.

description: We present high-resolution infrared spectroscopy of the Herbig Ae star HD 141569 A in the CO v=2-1 transition. With the angular resolution attained by the adaptive optics system, the gas disk around HD 141569 A is spatially resolved down to its inner-rim truncation. The size of the inner clearing is 11+-2 AU in radius, close to the gravitational radius of the star. The rough coincidence to the gravitational radius indicates that the viscous accretion working together with the photoevaporation by the stellar radiation has cleared the inner part of the disk.

description: No abstracts are to be cited without prior reference to the author. We discuss a situation when the assumption of exchangeability may be questionable in a typical management problem of an environmental system. We discuss in what way it may deteriorate quality in the following scientific advice if the solution was left unchanged. The discussion is illustrated by a case-study on the evaluation of clupeid reduction as a strategy to manage cod in the Baltic Sea.

The Law of one price

description: Η δημιουργία της Ευρωπαϊκής Ένωσης είναι ένας από τους σημαντικότερους σταθμούς στην ιστορία του διεθνούς οικονομικού συστήματος. Η σύνδεση οικονομικού πεπρωμένου χωρών μελών και η υιοθέτηση ενιαίων οικονομικών πολιτικών αποτελεί μια ριζική αλλαγή στην διευθέτηση κοινωνικών, πολιτικών και οικονομικών προβλημάτων των χωρών αυτών, καθώς και ολόκληρου του κόσμου.Στην παρούσα εργασία έγινε ένας εμπειρικός έλεγχος για να διαπιστώσουμε αν ισχύει ο νόμος της Ενιαίας Τιμής(LOOP) σε ένα σύνολο 15 Ευρωπαϊκών χωρών για 9 κατηγορίες τροφίμων, καθώς διαχρονικό παραμένει το ερώτημα στα σημαντικότερα μακροοικονομικά ζητήματα της Διεθνούς Οικονομίας εάν και πότε φτωχές περιοχές ή χώρες μπορούν να οδηγηθούν σε μία ολοκληρωμένη αγορά με τις πιο πλούσιες. Για την έρευνά μας χρησιμοποιήθηκαν ατομικοί έλεγχοι μοναδιαίας ρίζας καθώς και έλεγχοι μοναδιαίας ρίζας σε δεδομένα panel. Συγκεκριμένα καταλήξαμε στο συμπέρασμα ότι πράγματι στο σύνολο των panel ελέγχων έχει ισχύ ο «Νόμος της Ενιαίας Τιμής». Ενώ σε ότι αφορά τους ατομικούς ελέγχους τα αποτελέσματα ποικίλουν από χώρα σε χώρα και κατηγορία αγαθών.
description: This present study investigates the European Market and the relationship between integration and price convergence in international markets in 15 countries under the Law Of one Price(LOOP).There is a great controversy in whether the LOOP holds or not, especially in the European Market which is one history project that attracted so much attention in International Economics. Using a panel data set of prices in 9 identical goods of the food market, containing observations over the period 1996-2010, we found strong evidence in favor of the Law of one Price. After unit root tests and panel unit root tests our empirical results are an optimistic approach in the European Commission's efforts to achieve integration, while so long literature gives us the opposite results. The fact is that further research is necessary due to the importance of the topic.

description: We write a covariant transport equation for the phonon excitations of a relativistic superfluid valid at small temperatures. The hydrodynamical equations for this system are derived from the effective field theory associated to the superfluid phonons. We describe how to construct the kinetic theory for the phonon quasiparticles using a relativistic generalization of the analogue model of gravity developed by Unruh. This gravity analogy relies on the equivalence between the action of a phonon field moving in a superfluid background with that of a boson propagating in a given curved space-time. Exploiting this analogy we obtain continuity equations for the phonon current, entropy and energy-momentum tensor in a covariant form, valid in any reference frame. Our aim is to shed light on some aspects of transport phenomena of relativistic superfluidity. In particular, we are interested in the low temperature regime of the color flavor locked phase, which is a color superconducting and superfluid phase of high density QCD that may be realized in the core of neutron stars.

description: We report on the most complete investigation to date of the 4f-electron properties at the gamma-alpha transition in elemental Ce by resonant inelastic x-ray scattering (RIXS). The Ce 2p3d-RIXS spectra were measured directly in the bulk material as a function of pressure through the transition. The spectra were simulated within the Anderson impurity model. The occupation number nf was derived from the calculations in both gamma- and alpha-phases in the ground state along with the f doubleoccupancy. We find that the electronic structure changes result mainly from band formation of 4f electrons which concurs with reduced electron correlation and increased Kondo screening at high pressure.

description: No abstracts are to be cited without prior reference to the author. Hierarchical Bayesian methods are suitable for estimating reference points for data-poor stocks, as they can borrow strength from fisheries with more information. That is the case in the restricted whelk (Buccinum undatum) fishery in Iceland, which initiated in late 1990 with annual catches from almost zero to 1300 t. Recent recommendations have been based on average historical catch and logbook statistics. To get better estimate of whelk population dynamics, we used monthly-scaled CPUE data as an index of biomass in a Bayesian Schaefer surplus production model. Two models were compared: the first treated the fishery as one unit (“Simple” model), whereas the second analysed the fishery as being composed of 6 spatial sub-units (Hierarchical model). We imposed 3 different levels of fishing mortality to analyse the risk of high population depletion and also compared results when catches were evenly distributed over sub-units compared to status quo catch distributions. The hierarchical model seems better because it yields more flexibility to include trends among subareas that are not similar and it was not biased like the simple model. The results yield population parameter distributions that can be used as prior information for assessments of whelk elsewhere.
Quantized dynamics in closed quantum systems

description: We propose an approach to process data from interferometric measurements on a closed quantum system at random times. For this purpose a time correlation matrix is introduced which enables us to extract dynamical properties of the quantum system. After defining a generalized expectation value we obtain a distribution of time scales, an average transition time and a correlation time. A classical limit exists which is separated from the quantum fluctuations. The latter are characterized by resonances associated with poles of the generalized expectation value. Its analytic behavior is studied and some generic properties are linked to a quantized Berry phase.

description: The structural distortion and magnetoelastic coupling induced through commensurate magnetism has been investigated by neutron diffraction in structurally related MnWO$_4$ and NaFe(WO$_4$)$_2$. Both systems exhibit a competition of incommensurate spiral and commensurate spin up-up-down-down ordering along the magnetic chains. In the latter commensurate phases, the alternatingly parallel and antiparallel arrangement of Fe$^{3+}$ respectively Mn$^{2+}$ moments leads to sizeable bond-angle modulation and thus to magnetic dimerization. For NaFe(WO$_4$)$_2$ this structural distortion has been determined to be strongest for the low-field up-up-down-down arrangement, and the structural refinement yields a bond-angle modulation of $\pm 1.15(16)$ degrees. In the commensurate phase of MnWO$_4$, superstructure reflections signal a comparable structural dimerization and thus strong magneto-elastic coupling different to that driving the multiferroic order. Pronounced anharmonic second- and third-order reflections in the incommensurate and multiferroic phase of MnWO$_4$ result from tiny commensurate fractions that can depin multiferroic domains.

description: We here propose a model to simulate the process of opinion formation, which accounts for the mutual affinity between interacting agents. Opinion and affinity evolve self-consistently, manifesting a highly non trivial interplay. A continuous transition is found between single and multiple opinion states. Fractal dimension and signature of critical behaviour are also reported. A rich phenomenology is presented and discussed with reference to corresponding psychological implications.
