description: Suppose we have a pair of information channels, $κ_{1},κ_{2}$, with a common input. The Blackwell order is a partial order over channels that compares $κ_{1}$ and $κ_{2}$ by the maximal expected utility an agent can obtain when decisions are based on the channel outputs. Equivalently, $κ_{1}$ is said to be Blackwell-inferior to $κ_{2}$ if and only if $κ_{1}$ can be constructed by garbling the output of $κ_{2}$. A related partial order stipulates that $κ_{2}$ is more capable than $κ_{1}$ if the mutual information between the input and output is larger for $κ_{2}$ than for $κ_{1}$ for any distribution over inputs. A Blackwell-inferior channel is necessarily less capable. However, examples are known where $κ_{1}$ is less capable than $κ_{2}$ but not Blackwell-inferior. We show that this may even happen when $κ_{1}$ is constructed by coarse-graining the inputs of $κ_{2}$. Such a coarse-graining is a special kind of "pre-garbling" of the channel inputs. This example directly establishes that the expected value of the shared utility function for the coarse-grained channel is larger than it is for the non-coarse-grained channel. This contradicts the intuition that coarse-graining can only destroy information and lead to inferior channels. We also discuss our results in the context of information decompositions.

Open Strings and Electric Fields in Compact Spaces

description: We analyse open strings with background electric fields in the internal space, T-dual to branes moving with constant velocities in the internal space. We find that the direction of the electric fields inside a two torus, dual to the D brane velocities, has to be quantised such that the corresponding direction is compact. This implies that D-brane motion in the internal torus is periodic, with a periodicity that can be parametrically large in terms of the internal radii. By S-duality, this is mapped into an internal magnetic field in a three torus, a quantum mechanical analysis of which yields a similar result, i.e. the parallel direction to the magnetic field has to be compact. Furthermore, for the magnetic case, we find the Landau level degeneracy as being given by the greatest common divisor of the flux numbers. We carry on the string quantisation and derive the relevant partition functions for these models. Our analysis includes also the case of oblique electric fields which can arise when several stacks of branes are present. Compact dimensions and/or oblique sectors influence the energy loss of the system through pair-creation and thus can be relevant for inflationary scenarios with branes. Finally, we show that the compact energy loss is always larger than the non-compact one.

description: Combining results of T.K. Lam and J. Stembridge, the type $C$ Stanley symmetric function $F_w^C(\mathbf{x})$, indexed by an element $w$ in the type $C$ Coxeter group, has a nonnegative integer expansion in terms of Schur functions. We provide a crystal theoretic explanation of this fact and give an explicit combinatorial description of the coefficients in the Schur expansion in terms of highest weight crystal elements.

description: We consider a universe with an arbitrary number of extra dimensions, $N$. We present a new method for constructing the cosmological equations of motion and find analytic solutions with an explicit dependence on $N$. When we take the $N\rightarrow\infty$ limit we find novel, emergent behaviour which distinguishes it from normal Kaluza-Klein universes.

Το θέμα της συγκεκριμένης διπλωματικής εργασίας είναι η κακοποίηση των γυναικών και η ψυχοθεραπευτική αντιμετώπιση του στα πλαίσια της συμβουλευτικής διαδικασίας. Επιλέχτηκε το συγκεκριμένο θέμα λόγω της μεγάλης διάστασης του εν λόγου φαινομένου, καθώς μόνο ελάχιστα περιστατικά βίας μεταξύ των συζύγων ή των συντρόφων γίνονται γνωστά. Η κακοποίηση είναι ένα ιδιαίτερα συχνό φαινόμενο μεταξύ των συντρόφων. Η βία που πολλές φορές ασκεί ο δράστης της κακοποίησης στο θύμα μπορεί να λάβει διάφορες μορφές όπως είναι η σωματική βία, η λεκτική βία, η ψυχολογική βία κ.α. Δεν πρόκειται για στιγμιαίες καταστάσεις βίας, αλλά για μια χρόνια <<ασθένεια>> του ζευγαριού , η οποία έχει ως αποτέλεσμα τη συναισθηματική εξόντωση του θύματος. Η κακοποίηση μεταξύ των συντρόφων φτάνει αρκετές φορές ως την τέλεση ανθρωποκτονίας. Στόχος, λοιπόν, της παρούσης εργασίας είναι να περιγράψει το εν λόγω φαινόμενο και να αναδείξει τα αίτια του, τη πρόληψη και την αντιμετώπιση του. Επομένως, θα αναλυθούν οι διάφορες μορφές αντιμετώπισης που εφαρμόζονται ή προτείνονται προς εφαρμογή καθώς και τα αποτελέσματα τους
description: Violence against women of any form has long-term consequences for health, direct or indirect. Health professionals, therefore, can be the first persons to whom a woman will turn for help and support and consequently their role is particularly important. The subject of this particular thesis is the abuse of women and its psychotherapeutic treatment in the context of the counseling process. The specific topic was chosen due to the large dimension of the phenomenon in question, as only few incidents of violence between spouses or partners are known. Abuse is a particularly common phenomenon between partners. The violence that the abuser often inflicts on the victim can take various forms such as physical violence, verbal violence, psychological violence, etc. These are not momentary situations of violence, but a chronic "disease" of the couple, which results in the emotional destruction of the victim. Abuse between partners often goes as far as committing murder. Therefore, the aim of this work is to describe this phenomenon and highlight its causes, prevention and treatment. Therefore, the various forms of treatment implemented or proposed for implementation will be analyzed as well as their results

description: In this article we study optimal control problems for systems that are affine with respect to some of the control variables and nonlinear in relation to the others. We consider finitely many equality and inequality constraints on the initial and final values of the state. We investigate singular optimal solutions for this class of problems, for which we obtain second order necessary and sufficient conditions for weak optimality in integral form. We also derive Goh pointwise necessary optimality conditions. We show an example to illustrate the results.

Post-Keplerian effects on radial velocity in binary systems and the possibility of measuring General Relativity with the S2 star in 2018

description: One of the directly measured quantities which are used in monitoring the orbital motions of many of the S stars revolving around the Supermassive Black Hole (SMBH) in the Galactic Center (GC) is their radial velocity (RV) $V$ obtained with near-infrared spectroscopy. Here, we devise a general approach to calculate both the instantaneous variations $ΔV\left(t\right)$ and the net shifts per revolution $\left\langleΔV\right\rangle$ induced on such an observable by some post-Keplerian (pK) accelerations. In particular, we look at the general relativistic Schwarzschild (gravitoelectric) and Lense-Thirring (gravitomagnetic frame-dragging) effects, and the mass quadrupole. It turns out that we may be on the verge of measuring the Schwarzschild-type 1pN static component of the SMBH's field with the S2 star for which RV measurements accurate to about $\simeq 30-50~\textrm{km s}^{-1}$ dating back to $t_0 = 2003.271$ are currently available, and whose orbital period amounts to $P_\textrm{b} = 16$ yr. Indeed, while its expected general relativistic RV net shift per orbit amounts to just $\left\langleΔV^\textrm{GE}\right\rangle = -11.6~\textrm{km s}^{-1}$, it should reach a peak value as large as $ΔV_\textrm{max}^\textrm{GE}\left(t_\textrm{max}\right) = 551~\textrm{km s}^{-1}$ at $t_\textrm{max} = 2018.35$. The periastron shift $Δω^\textrm{GE}$ of S2 over the same time span will not be larger than $0.2$ deg, while the current accuracy in estimating such an orbital element for this star is of the order of $0.6$ deg. The frame-dragging and quadrupole-induced RV shifts are far smaller for S2, amounting to, at most, $0.19~\textrm{km s}^{-1},0.0039~\textrm{km s}^{-1}$, respectively. Further studies should be dedicated to the impact on the RV of possible diffused mass distribution in the GC and of other individual stars inside and outside the orbit of S2.

description: In this paper we give a simple proof of the existence of global-in-time smooth solutions for the convective Brinkman-Forchheimer equations (also called in the literature the tamed Navier-Stokes equations) $$ \partial_tu -μΔu + (u \cdot \nabla)u + \nabla p + αu + β|u|^{r - 1}u = 0 $$ on a $3$D periodic domain, for values of the absorption exponent $r$ larger than $3$. Furthermore, we prove that global, regular solutions exist also for the critical value of exponent $r = 3$, provided that the coefficients satisfy the relation $4μβ\geq 1$. Additionally, we show that in the critical case every weak solution verifies the energy equality and hence is continuous into the phase space $L^2$. As an application of this result we prove the existence of a strong global attractor, using the theory of evolutionary systems developed by Cheskidov.

description: In a seminal paper [D. N. Page, Phys. Rev. Lett. 71, 1291 (1993)], Page proved that the average entanglement entropy of subsystems of random pure states is $S_{\rm ave}\simeq\ln{\cal D}_{\rm A} - (1/2) {\cal D}_{\rm A}^2/{\cal D}$ for $1\ll{\cal D}_{\rm A}\leq\sqrt{\cal D}$, where ${\cal D}_{\rm A}$ and ${\cal D}$ are the Hilbert space dimensions of the subsystem and the system, respectively. Hence, typical pure states are (nearly) maximally entangled. We develop tools to compute the average entanglement entropy $\langle S\rangle$ of all eigenstates of quadratic fermionic Hamiltonians. In particular, we derive exact bounds for the most general translationally invariant models $\ln{\cal D}_{\rm A} - (\ln{\cal D}_{\rm A})^2/\ln{\cal D} \leq \langle S \rangle \leq \ln{\cal D}_{\rm A} - [1/(2\ln2)] (\ln{\cal D}_{\rm A})^2/\ln{\cal D}$. Consequently we prove that: (i) if the subsystem size is a finite fraction of the system size then $\langle S\rangle

Μέσα σ’ αυτό το πλαίσιο περιστέλλονται δικαιώματα, συρρικνώνεται η νομική προστασία και το κοινωνικό κράτος δικαίου, υποβιβάζεται η ποιότητα διαβίωσης και θίγεται η ακεραιότητα και αξιοπρέπεια της ζωής.

description: Subjectivity under a debt regime: In the context of neoliberalism, debt, under "state of exception" conditions, is established as a technique of state governance and as a mechanism of subjects’ control. Within this context, rights are curtailed, legal protection and the social rule of law are eroded, the quality of living is degraded and life’s integrity and dignity is insulted. Thus, vulnerabilities, such as directly or indirectly indebted persons, are exposed to conditions that tend to the extremity of "bare life". Hence, in this thesis, the life of indebted subjects is being under investigation, under discussion with them, and under defensive argumentation. Argumentation which, with restrained optimism, invites to: critical reflection, seeking answers, social awareness and action, before it is too late, before the social contract is generally thwarted and Democracy irreparably damaged

description: The recent realization of single electron sources let us envision performing electron quantum optics experiments, where electrons can be viewed as flying qubits propagating in a ballistic conductor. To date, all electron sources operate in a periodic electron injection mode leading to energy spectrum singularities in various physical observables which sometimes hide the bare nature of physical effects. To go beyond this, we propose a spread-spectrum approach where electron flying qubits are injected in a non-periodic manner following a pseudorandom binary bit pattern. Extending the Floquet scattering theory approach from periodic to spread-spectrum drive, the shot noise of pseudorandom binary sequences of single electron injection can be calculated for leviton and non-leviton sources. Our new approach allows us to disentangle the physics of the manipulated excitations from that of the injection protocol. In particular, the spread spectrum approach is shown to provide a better knowledge of electronic Hong Ou Mandel correlations and to clarify the nature of the pulse train coherence and the role of the dynamical orthogonality catastrophe for non-integer charge injection.

description: We present a study of transverse single-spin asymmetries (SSAs) in $p^\uparrow p\to J/ψ\,X$ and $p^\uparrow p\to D X$ within the framework of the generalized parton model (GPM), which includes both spin and transverse momentum effects, and show how they can provide useful information on the still almost unknown gluon Sivers function. Moreover, by adopting a modified version of this model, named color gauge invariant (CGI) GPM, we analyze the impact of the initial- and final-state interactions on our predictions. As a consequence, we find that these two processes are sensitive to different gluon Sivers functions, which can be expressed as linear combinations of two distinct, universal gluon distributions. We therefore define proper observables which could allow for a separate extraction of these two independent Sivers functions. At the same time, we show how it would be possible to discriminate between the GPM and the CGI-GPM approaches by comparing the corresponding estimates of SSAs with present and future experimental results at RHIC.

description: Γενικά, με τον όρο ακούσια νοσηλεία νοείται η επιβολή ενός ante delictum αναγκαστικού μέτρου περιορισμού σε ψυχιατρική κλινική, άνευ συγκαταθέσεως, ασθενών που πάσχουν από κάποια ψυχική νόσο και πληρούν συγκεκριμένες προϋποθέσεις όπως ρητά αυτές ορίζονται από τους Ν. 2071/1992 και Ν. 2716/1999. Απαιτεί την ύπαρξη ψυχικής ασθένειας η οποία να περιορίζει σε τέτοιο βαθμό την κριτική ικανότητα του ατόμου, που να καθίσταται αδύνατον για αυτόν να αποφασίσει για το συμφέρον της υγείας του, και παράλληλα η μη αναγκαστική εισαγωγή του σε κάποιο ψυχιατρικό νοσοκομειακό ίδρυμα, να αποτελεί ενέργεια, που εν δυνάμει μπορεί να δυσχεράνει σημαντικά την κατάσταση της υγείας του ασθενή και να αυξάνει την επικινδυνότητα βίαιης ετεροκαταστροφικής και αυτοκαταστροφικής συμπεριφοράς από πλευράς του. Κατά την διαδικασία της ακουσίας νοσηλείας, πρέπει να λαμβάνονται υπόψιν όχι μόνο αυτή καθαυτή ασθένεια του ατόμου, αλλά και άλλοι ψυχοκοινωνική παράγοντες που παίζουν ρόλο, με σκοπό όχι μόνο την βραχύχρονη βελτίωση του ασθενή αλλά και την μετέπειτα εξέλιξη του. Το κοινωνικό στίγμα, το φαινόμενο ‘’Why try’’ και τα μέσα ενημέρωσης, είναι μερικοί από τους παράγοντες που διαδραματίζουν σημαντικό ρόλο στη διαδικασία. Η συνδρομή της αστυνομίας στη διαδικασία είναι εξ’ ίσου σημαντική και θα πρέπει να αντιμετωπίζει τον ψυχικά ασθενή με επίγνωση και σεβασμό των δικαιωμάτων του και όχι σαν τυπικός εγκληματίας κατά την διαδικασία της ακούσιας νοσηλείας
description: In general, the term involuntary hospitalization means the imposition of an ante delictum compulsory measure of confinement in a psychiatric clinic, without consent, of patients who suffer from a mental illness and meet specific conditions as expressly defined by Laws 2071/1992 and Law 2716/ 1999. It requires the existence of a mental illness that limits the judgment of the person to such an extent, that it becomes impossible for him to decide in the interest of his health, and at the same time or not forced admission to a psychiatric hospital institution, to be an action that can potentially significantly complicate the patient's health condition and that does not limit the risk of violent heterodestructive and self-destructive behavior. During the process of medical care, not only the individual's illness as such must be taken into account, but also other psychosocial factors that play a role, with the aim of not only the short-term improvement of the patient but also his subsequent development. Social stigma, why try effect and media, are some of the important factors that play a vital role in the process. The assistance of the police in the process is important and they should treat the mentally ill with awareness and respect for his rights and not criminalize him as a common offender during the procedure

description: We report the results from our analysis of 8 years of the data for the gamma-ray binary LS I +61 303, obtained with the Large Area Telescope onboard the Fermi Gamma-Ray Space Telescope. We find a significant dip around the binary's periastron in the superorbital light curves, and by fitting the light curves with a sinusoidal function, clear phase shifts are obtained. The superorbital modulation seen in the binary has been long known and different scenarios have been proposed. Based on our results, we suggest that the circumstellar disk around the Be companion of this binary has an elliptical shape and the major axis of the disk rotates at the superorbital period of 1667 days. As a result, the density of the ambient material around the compact star of the binary changes along the binary orbit over the superorbital period, causing the phase shifts in the modulation, and around periastron, the compact star probably enters the disk, causing the appearance of the dip. Numerical simulations may be conducted in order to study the detailed physical processes and verify our suggestion.

description: Time delays may cause dramatic changes to the dynamics of interacting oscillators. Coupled networks of interacting dynamical systems can behave unexpectedly when the signal between the vertices are time delayed. It has been shown for a very general class of systems that the time delays can be rearranged as long as the total time delay over the constitutive loops of the network is conserved. This fact allows to reduce the number of time delays of the problem without loss of information. There is a theoretical lower bound for this number, but in many cases we can find a numerical solution that beats this limit. Here we propose a formulation of the problem and a numerical method to even further reduce the number of time delays in a network.

description: Commercial transactions rule our daily lives, are carried out in Greek territory, within the European Union and outside of the European Union. The generative cause of problems, especially in a business-to-business transaction, emanates from the impossibility of proper description, assignment of responsibility and carrying out the necessary operations at every stage and aspect of the transaction. The protection of the smoothness of the commercial transaction and the avoidance of distortions are critical requirements for all trading businesses. The present thesis will focus on the commercial transaction of materials and non-hazardous goods between a Greek business and a business outside the European Union. It will detect all necessary operations at all stages, it will highlight the legal framework governing foreign trade between businesses and the necessary international terms and rules of the ICC which need to be used in such commercial transaction to ensure its smoothness and to avoid " Unanticipated consequences", in all its aspects

description: Effects of the isospin-symmetry breaking (ISB) beyond mean-field Coulomb terms are systematically studied in nuclear masses near the $N=Z$ line. The Coulomb exchange contributions are calculated exactly. We use extended Skyrme energy density functionals (EDFs) with proton-neutron-mixed densities, to which we add new terms breaking the isospin symmetry. Two parameters associated with the new terms are determined by fitting mirror and triplet displacement energies (MDEs and TDEs) of isospin multiplets. The new EDFs reproduce MDEs for the $T=\frac12$ doublets and $T=1$ triplets, and TDEs for the $T=1$ triplets. Relative strengths of the obtained isospin-symmetry-breaking terms {\em are not} consistent with the differences in the $NN$ scattering lengths, $a_{nn}$, $a_{pp}$, and $a_{np}$. Based on low-energy experimental data, it seems thus impossible to delineate the strong-force ISB effects from beyond-mean-field Coulomb-energy corrections.

description: We consider a Rashba nanowire with proximity gap which can be brought into the topological phase by tuning external magnetic field or chemical potential. We study spin and charge of the bulk quasiparticle states when passing through the topological transition for open and closed systems. We show, analytically and numerically, that the spin of bulk states around the topological gap reverses its sign when crossing the transition due to band inversion, independent of the presence of Majorana fermions in the system. This spin reversal can be considered as a bulk signature of topological superconductivity that can be accessed experimentally. We find a similar behaviour for the charge of the bulk quasiparticle states, also exhibiting a sign reversal at the transition. We show that these signatures are robust against random static disorder.

description: We derive new representations of the Einstein-Hilbert action in which graviton perturbation theory is immensely simplified. To accomplish this, we recast the Einstein-Hilbert action as a theory of purely cubic interactions among gravitons and a single auxiliary field. The corresponding equations of motion are the Einstein field equations rewritten as two coupled first-order differential equations. Since all Feynman diagrams are cubic, we are able to derive new off-shell recursion relations for tree-level graviton scattering amplitudes. With a judicious choice of gauge fixing, we then construct an especially compact form for the Einstein-Hilbert action in which all graviton interactions are simply proportional to the graviton kinetic term. Our results apply to graviton perturbations about an arbitrary curved background spacetime.

description: An important class of observables for gravitational waves consists of the fluxes of energy, momentum and angular momentum carried away by them and are well understood for weak gravitational waves in Minkowski background. In de Sitter background, the future null infinity, $\mathcal{J}^+$, is space-like which makes the meaning of these observables subtle. A spatially compact source in de Sitter background also provides a distinguished null hypersurface, its {\em cosmological horizon}, $\mathcal{H}^+$. For sources supporting the short wavelength approximation, we adopt the Isaacson prescription to define an effective gravitational stress tensor. We show that the fluxes computed using this effective stress tensor can be evaluated at $\mathcal{H}^+$, match with those computed at $\mathcal{J}^+$ and also match with those given by Ashtekar et al at $\mathcal{J}^+$ {\em at a coarse grained level}.

description: Η παρούσα διπλωματική εργασία είχε σκοπό να μεταφράσει και να σταθμίσει στην ελληνική γλώσσα το ερωτηματολόγιο της Ryff Six factor Model of Psychological Well-Being (84 item) και να αξιολογήσει τη σχέση του με τις κλίμακες άγχους (STAI), της κατάθλιψης (CES-D) και της αυτοκτονικότητας (RASS). Το ερωτηματολόγιο Six factor Model of Psychological Well-Being (84 item) είναι ένα αυτοσυμπληρούμενο ερωτηματολόγιο και δεν αποτελεί την πιο σύντομη εκδοχή του καθώς περιλαμβάνει 84 στοιχεία με σκοπό να μετρήσει την ευζωία. Η Carol Ryff το 1989 χρησιμοποίησε τις υπάρχουσες θεωρίες και ανέπτυξε το μοντέλο ψυχολογικής ευημερίας το οποίο αποτελείται από έξι παράγοντες οι οποίοι είναι: Αυτονομία, Περιβαλλοντική Κυριαρχία, Προσωπική Ανάπτυξη, Θετικές Σχέσεις με τους άλλους, Σκοπό στη ζωή και Αυτο-Αποδοχή. Η συσχέτιση του με τις άλλες κλίμακες ελέγχθηκε με τον συντελεστή συσχέτισης Pearson και τα δεδομένα της παρούσας μελέτης έδειξαν πως η εσωτερική δομή διαφέρει από το πρωτότυπο μοντέλο. Η ελληνική έκδοση του ερωτηματολογίου Six factor Model of Psychological Well-Being δεν φάνηκε να είναι ένα αξιόπιστο εργαλείο μέτρησης της ευζωίας στον ελληνικό πληθυσμό
description: The aim of this thesis was to translate and measure in the Greek language Ryff’s Six factor Model of Psychological Well-Being (84 item) questionnaire and to assess its relationship with measurements of anxiety (STAI), depression (CES-D) and suicidality (RASS). The Six factor Model of Psychological Well-Being (84 item) is a self-reported questionnaire, and it is not the shortest version as it includes 84 items to measure the wellbeing. Carol Ryff in 1989 used the existing theories and developed the model of psychological wellbeing which consists of six factors: Autonomy, Environmental Mastery, Personal Growth, Positive Relations with others, Purpose in life and Self-Acceptance. The correlations with other scales were examined with the Pearson correlation coefficient and the data of the present study showed that the internal structure differs from the original model. The Greek version of the Six factor Model of Psychological Well-Being questionnaire is not an appropriate tool for measuring the well-being in the Greek population
Entropy-Preserving Coupling Conditions for One-dimensional Euler Systems at Junctions

description: This paper is concerned with a set of novel coupling conditions for the $3\times 3$ one-dimensional Euler system with source terms at a junction of pipes with possibly different cross-sectional areas. Beside conservation of mass, we require the equality of the total enthalpy at the junction and that the specific entropy for pipes with outgoing flow equals the convex combination of all entropies that belong to pipes with incoming flow. Previously used coupling conditions include equality of pressure or dynamic pressure. They are restricted to the special case of a junction having only one pipe with outgoing flow direction. Recently, Reigstad [SIAM J. Appl. Math., 75:679--702, 2015] showed that such pressure-based coupling conditions can produce non-physical solutions for isothermal flows through the production of mechanical energy. Our new coupling conditions ensure energy as well as entropy conservation and also apply to junctions connecting an arbitrary number of pipes with flexible flow directions. We prove the existence and uniqueness of solutions to the generalised Riemann problem at a junction in the neighbourhood of constant stationary states which belong to the subsonic region. This provides the basis for the well-posedness of the homogeneous and inhomogeneous Cauchy problems for initial data with sufficiently small total variation.

description: The objective of this paper is to determine the lattices of minimal covolume in SL_n(R), for n greater than 3. The answer turns out to be the simplest one: SL_n(Z) is, up to automorphism, the unique lattice of minimal covolume in SL_n(R). In particular, lattices of minimal covolume in SL_n(R) are non-uniform when n is greater than 3, contrasting with Siegel's result for SL_2(R). This answers for SL_n(R) the question of Lubotzky: is a lattice of minimal covolume typically uniform or not?

description: The learner’s awareness of his cognitive processes and his control over the various metacognitive components is the basis of methodological competencies, as the priority of educational systems seeking to improve the level of effectiveness of strategic choices and improving learning outcomes with an economy in effort and time. Our analytical approach concluded that the learner's awareness of his cognitive processes and the knowledge associated with the tasks and situations that contain cognitive activity are metacognitive components as the conversation about metacognitive awareness is not possible except in the presence of the same learner as a metacognitive actor capable of various intellectual processes used in learning situations. This relationship suggests a future in which educational practices can best support the lifelong learning and sustainable development. Therefore, any strategic choice, whether at the level of treatment or at the level of execution, is a reflection of the learner's awareness of his cognitive processes in the various stages of performance. Metacognitive is a conscious process that refers to the knowledge of what the individual knows and the states of knowledge in the relationship with associated factors then monitoring and organizing them consciously, dynamically and intentionally, in order to improve the performance of achievement paths effectively, in order to build a new knowledge directed towards the future, allowing a person to meet his cognitive and socio-emotional needs in relation to the other and the world. In this research, a number of related concepts will bereviewed in view of their role in learning and knowledge building, especially with the widening gap between educational field practice and the true needs of learners. It also aims to improve the learning outcomes by providing the learner with motivational, emotional, strategic and cognitive skills in order to achieve personal goals intrinsically and externally.
Measurement of double-differential cross sections for top quark pair production in pp collisions at sqrt(s) = 8 TeV and impact on parton distribution functions

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Normalized double-differential cross sections for top quark pair (t t-bar) production are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7 inverse femtobarns. The measurement is performed in the dilepton e+/- mu-/+ final state. The t t-bar cross section is determined as a function of various pairs of observables characterizing the kinematics of the top quark and t t-bar system. The data are compared to calculations using perturbative quantum chromodynamics at next-to-leading and approximate next-to-next-to-leading orders. They are also compared to predictions of Monte Carlo event generators that complement fixed-order computations with parton showers, hadronization, and multiple-parton interactions. Overall agreement is observed with the predictions, which is improved when the latest global sets of proton parton distribution functions are used. The inclusion of the measured t t-bar cross sections in a fit of parametrized parton distribution functions is shown to have significant impact on the gluon distribution.

Their result refines the standard existence and uniqueness of saturated models. They express a wish to obtain a unified approach in the context of category theory. We provide this in the framework of weak factorization systems. Our basic tool is the fat small object argument.
Effect of free surface on submerged stratified shear instabilities

description: Here we have considered the effects of shallowness of the domain as well as the air-water free surface on the stratified shear instabilities of the fluid underneath. First, we numerically solve the non-Boussinesq Taylor-Goldstein equation for smooth velocity and density profiles of a model shear layer with a free surface. When the depth of the fluid is relatively shallow compared to the shear layer thickness, the surface gravity waves existing at the free surface come closer to the waves existing in the shear layer. This can lead to resonant wave interactions, making the flow unstable to more varieties of modal instabilities. To obtain a deeper understanding of the instability mechanisms, we have performed analytical studies with broken-line profiles. Furthermore, reduced order broken-line profiles have also been developed, based on which dispersion diagrams are constructed. Through these diagrams we have underpinned the resonantly interacting waves leading to each type of instability. Two new instabilities have been found; one of them, referred to as the surface gravity - interfacial gravity (SG-IG) mode, arises due to the interaction between a surface gravity wave and an interfacial gravity wave, and would be absent if there is no internal density stratification. The other one - the surface gravity - lower vorticity (SG-LV) mode, which arises due to the interaction between a surface gravity wave and the lower vorticity wave, surpasses Kelvin-Helmholtz instability to become the most unstable mode. Except for Holmboe instability, remarkable differences are observed in all other instabilities occurring in shallow domains when the air-water interface is replaced by a rigid lid. We infer that the rigid-lid approximation is valid for large vertical domains. We have also shown that if shear is absent at the free surface, our problem can be modeled using a Boussinesq type approximation.
