description: Στη σύγχρονη κοινωνία τα πρότυπα, που συνεχώς προβάλλονται συνδέουν την ελκυστικότητα, την επιτυχία αλλά πολλές φορές και την υγεία με ένα καλλίγραμμο και λεπτό σώμα και μια ιδιαίτερη σωματική εμφάνιση. H παρούσα έρευνα πραγματοποιήθηκε με σκοπό να διερευνήσει τους λόγους συμμετοχής στην άσκηση, τις διατροφικές στάσεις και την εικόνα του σώματος σε επαγγελματίες εκπαιδευτές σωματικών και αθλητικών δραστηριοτήτων. Το σύνολο του δείγματος αποτέλεσαν 121 προπονητές/τριες, οι οποίοι ταξινομήθηκαν σε δύο ομάδες. Την πρώτη ομάδα αποτέλεσαν 83 προπονητές/τριες ατομικών αθλημάτων (αϊκίντο, ζίου ζίτσου, καράτε, τζούντο, τάε κβο ντο, μουάι τάι, κραβ μαγκά, κικ μπόξινγκ, πυγμαχία, πάλη), ενώ τη δεύτερη, 38 προπονητές/τριες ομαδικών αθλημάτων (πετοσφαίριση, καλαθοσφαίριση, χειροσφαίριση, ποδόσφαιρο). Από την ανάλυση των αποτελεσμάτων διαπιστώθηκαν στατιστικά σημαντικές διαφορές μεταξύ των εκπαιδευτών ατομικών αθλημάτων και μεταξύ των εκπαιδευτών ομαδικών αθλημάτων, ως προς τον παράγοντα διατροφικές στάσεις και ως προς τον παράγοντα παρακίνηση για απώλεια σωματικού βάρους. Δεν διαπιστώθηκαν στατιστικά σημαντικές διαφορές μεταξύ των εκπαιδευτών ατομικών αθλημάτων και μεταξύ των εκπαιδευτών ομαδικών αθλημάτων, ως προς τον παράγοντα αυτοεκτίμηση και ως προς τον παράγοντα σωματική δυσαρέσκεια. Συμπερασματικά, από την ανάλυση των αποτελεσμάτων φάνηκε, πως το υγιές σωματικό βάρος, οι υγιείς διατροφικές συνήθειες, καθώς και η μη ύπαρξη σωματικής δυσαρέσκειας, μπορούν να αποτελέσουν παράγοντες διαφοροποίησης των αποτελεσμάτων
description: Today, patterns that are constantly being projected, link the attractiveness, the success, and sometimes the health, with a slim body and a special body appearance. The aim of this study was to investigate the reasons for exercise, eating attitudes and body image in professional physical and athletic instructors. The total sample consisted of 121 coaches, who were classified into two groups. The first group consisted of 83 individual sports coaches (aikido, jiu jitsu, karate, judo, tae kwon do, muay thai, krav maga, kickboxing, boxing, wrestling) and the second one, of 38 team sports coaches, (volleyball, basketball, handball, football). The analysis of the results revealed statistically significant differences between individual sports instructors and between team sports instructors, in the eating attitudes factor and drive for thinness factor. There were no statistically significant differences between individual sports instructors and between team sports instructors, in the self-esteem factor and body dissatisfaction factor. In conclusion, from the analysis of the results it appeared that healthy body weight, healthy eating habits, and lack of body dissatisfaction can be factors that can make a difference to the results

description: Non-equilibrium Molecular Dynamics (NEMD) calculations of the bulk viscosity of the triple point Lennard-Jones fluid are performed with the aim of investigating the origin of the observed disagreement between Green-Kubo estimates and previous NEMD data. We show that a careful application of the Doll's perturbation field, the dynamical NEMD method, the instantaneous form of the perturbation and the "subtraction technique" provides a NEMD estimate of the bulk viscosity at zero field in full agreement with the value obtained by the Green-Kubo formula. As previously reported for the shear viscosity, we find that the bulk viscosity exhibits a large linear regime with the field intensity which confirms the Lennard-Jones fluid as a genuine Newtonian fluid even at triple point.

description: Η παρούσα έρευνα εξετάζει την χρησιμότητα ενός προγράμματος ψυχοεκπαίδευσης στη σχιζοφρένεια και διαχείρισης του άγχους με «Εστίαση της Προσοχής στην Εμπειρία στο Παρόν» («ΕΠΕΠ») σε συγγενείς-φροντιστές, ως προς τις γνώσεις για τη σχιζοφρένεια, την ικανότητα για ΕΠΕΠ, την επιβάρυνση από το ρόλο του φροντιστή, το εκφρασμένο συναίσθημα, τα αρνητικά συναισθήματα, το στρες, την κακή διάθεση, τη γενική ψυχική υγεία και την αποδοχή. Το πρόγραμμα είχε διάρκεια οχτώ εβδομάδες και απαρτιζόταν από δίωρες συναντήσεις, διχοτομημένες στην ψυχοεκπαίδευση και στην εξάσκηση στην ΕΠΕΠ. Στις συμμετέχουσες (N=15) χορηγήθηκαν, πριν και μετά την ολοκλήρωση του προγράμματος, ερωτηματολόγια για την καθεμία υπό εξέταση έννοια και ελέγχθηκαν οι διαφορές στις δύο φάσεις μέτρησης. Βρέθηκε στατιστικώς σημαντική αύξηση των γνώσεων για τη σχιζοφρένεια, μείωση της επιβάρυνσης και του εκφρασμένου συναισθήματος και βελτίωση στη γενική ψυχική υγεία, ενώ δεν σημειώθηκαν σημαντικές αλλαγές στην ικανότητα για ΕΠΕΠ, τα αρνητικά συναισθήματα, το στρες, την κακή διάθεση και την αποδοχή. Οι συμμετέχουσες δήλωσαν ότι απέκτησαν νέες γνώσεις και ότι ήταν ικανοποιημένες από το πρόγραμμα. Από τα αποτελέσματα φαίνεται ότι το πρόγραμμα ήταν ωφέλιμο, ωστόσο, η μη επιβεβαίωση όλων των υποθέσεων και οι μεθοδολογικοί περιορισμοί, καθιστούν χρήσιμη την περαιτέρω έρευνα
description: The aim of the present study was to assess the effects of a psychoeducation and mindfulness-based stress reduction (MSBR) program to family-caregivers of individuals with schizophrenia. The goal of the intervention was to increase knowledge about schizophrenia, a mindfulness stance and acceptance and to lessen caregiver burden, expressed emotion, negative emotions, perceived-stress, bad mood and general mental health problems. The intervention consisted of eight-sessions, based on a group format. Each session lasted two hours and had both a psychoeducation and a MSBR component. The participants (N=15) completed self-report measures, before and after the intervention. The results showed increase in knowledge, decreases in caregiver burden and expressed emotion and improvement in general mental health. No significant differences were found for mindfulness, negative emotions, perceived-stress, bad mood and acceptance, although the changes were in the right direction. The participants reported that they gained new knowledge and that they were satisfied by the program. These results indicate that the program was effective. Nevertheless, not all the measures showed significant improvement and there were several methological problems in the design. Replication of the findings with a larger sample would be very important

description: We compute thermal 2-point correlation functions in the black brane $AdS_5$ background dual to 4d CFT's at finite temperature for operators of large scaling dimension. We find a formula that matches the expected structure of the OPE. It exhibits an exponentiation property, whose origin we explain. We also compute the first correction to the two-point function due to graviton emission, which encodes the proper time from the event horizon to the black hole singularity.

Electrode configurations within boreholes

description: The subject of this thesis is the study of the applicability of cross borehole electrical resistivity tomography method within plastic cased slotted boreholes. The study involves both experimental and field data trials. Experimental tests involved performing cross-hole ERT measurements in a tank environment using model plastic PVC cased slotted boreholes, of different slot density, using different electrode configurations, aiming to relate the applicability of this measurement set-up with the density of the borehole slots. Cross-hole ERT data were also collected between plastic cased monitoring boreholes placed along the Thessaloniki metro line, which is under construction. Finally, measuring strategies between boreholes were also proposed to overcome the limitation of the analysis of the geoelectrical imaging of the subsurface, due to the long distance between the boreholes, either involving ERT surface measurements to the cross-hole ERT data or applying the borehole-to-surface ERT arrangement.

description: The magnetic properties of the $Fe_{1-x}Ru_x$ alloy system for 0 $\leq$ x $\leq$ 0.10 are studied by using a mean-field approximation based on the Bogoliubov inequality. Ferromagnetic Fe-Fe spin correlations and antiferromagnetic Fe-Ru and Ru-Ru exchanges have been considered to describe the temperature dependence of the Curie temperature and low temperature magnetization. A composition dependence has been imposed in the exchange couplings, as indicated by experiments. From a least-square fitting procedure to the experimental results an estimation of the interaction parameters was obtained, which yielded the low temperature dependence of the magnetization and of the ferromagnetic Curie temperature. A good agreement was obtained with available experimental results.

description: Quantum bits based on Majorana zero modes are expected to be robust against certain noise types, and hence provide a quantum computing platform that is superior to conventional qubits. This robustness is not complete though: imperfections can still lead to qubit decoherence and hence to information loss. In this work, we theoretically study Majorana-qubit dephasing in a minimal model: in a Kitaev chain with quasistatic disorder. Our approach, based on numerics as well as first-order non-degenerate perturbation theory, provides a conceptually simple physical picture and predicts Gaussian dephasing. We show that, as system parameters are varied, the dephasing rate due to disorder oscillates out-of-phase with respect to the oscillating Majorana splitting of the clean system. In our model, first-order dephasing sweet spots are absent if disorder is uncorrelated. We describe the crossover between uncorrelated and highly correlated disorder, and show that dephasing measurements can be used to characterize the disorder correlation length. We expect that our results will be utilized for the design and interpretation of future Majorana-qubit experiments.

description: Ο Ισοκράτης στην Ελένην του πραγματεύεται τον μύθο της Ελένης, με σκοπό να αναδείξει την αξία της. Προκειμένου ο ρήτορας να στοιχειοθετήσει τη δύναμη του κάλλους της Ελένης, εισάγει τα εμβόλιμα εγκώμια του Θησέα (18-38) και του Πάρη (41-48). Η εισαγωγή εμβόλιμων εγκωμίων στους επιδεικτικούς λόγους υπήρξε προσφιλής ρητορική τεχνική του Ισοκράτη. Άλλα τέτοια παραδείγματα ένθετων εγκωμίων αποτελούν το εγκώμιο του Αγαμέμνονα στον Παναθηναϊκόν (74-87), του Τιμόθεου στον Περί Αντιδόσεως (101-139) και του Ηρακλή στον Φίλιππον (109-112). Αντικείμενο της παρούσας ερευνητικής εργασίας είναι η διερεύνηση της λειτουργικότητας των ένθετων εγκωμίων του Θησέα και του Πάρη στον συνολικό έπαινο της Ελένης και η αξιοποίηση των μυθικών προσώπων, της Ελένης, του Θησέα και του Πάρη, ως μέσων προβολής των παιδαγωγικών και πολιτικών ιδεών του Ισοκράτη. Από την παραπάνω εργασία συνάγεται το γενικό συμπέρασμα πως οι έπαινοι του Θησέα και του Πάρη συμβάλλουν στην ανάδειξη της αξίας της Ελένης, ενώ ταυτόχρονα τα μυθικά πρόσωπα, Ελένη, Θησέας και Πάρης, μετατρέπονται σε πρότυπα προς μίμηση και οχήματα συγκεκριμένων αξιών της ισοκρατικής ιδεολογίας, όπως είναι το κάλλος, η σωφροσύνη και η φρόνησις
description: Isocrates in Helen addresses the myth of Helen, in order to highlight her value. In order for the orator to establish the power of Helen's beauty, he introduces the embedded encomia of Theseus (18-38) and Paris (41-48). The introduction of embedded encomia for the sake of demonstration has been a favorite rhetorical technique of Isocrates. Other such examples of embedded encomia are the praise of Agamemnon in Panathenaicus (74-87), Timotheus in Antidosis (101-139) and Heracles in Philippus (109-112). The purpose of this research is to investigate the functionality of the encomia of Theseus and Paris in the total praise of Helen and the exploitation of the mythical persons, Helen, Theseus and Paris, as a means of projecting the pedagogical and political ideas of Isocrates. From the above work we can conclude that the praise of Theseus and Paris contributes to the elevation of Helen's worth, while at the same time the mythical figures, Helen, Theseus and Paris, are transformed into imitation models and vehicles of certain values of the isocratic ideology, such as κάλλος, σωφροσύνη and φρόνησις

description: In two remarkable recent papers, hep-th/0610248 and hep-th/0610251, the complete planar perturbative expansion was proposed for the universal function of the coupling, f(g), appearing in the dimensions of high-spin operators of the N=4 SYM theory. We study numerically the integral equation derived in hep-th/0610251, which implements a resummation of the perturbative expansion, and find a smooth function that approaches the asymptotic form predicted by string theory. In fact, the two leading terms at strong coupling match with high accuracy the results obtained for the semiclassical folded string spinning in $AdS_5$. This constitutes a remarkable confirmation of the AdS/CFT correspondence for high-spin operators, and equivalently for the cusp anomaly of a Wilson loop. We also make a numerical prediction for the third term in the strong coupling series.

description: The present study aims to investigate the executive functions of people diagnosed with Mild Cognitive Impairment (MCI), through behavioral scales and performance tests, the awareness of their executive behavioral difficulties and the prediction of functioning by executive measurements (behavioral and cognitive performance). The study involved 46 people with a four year diagnosis of MCI and 38 healthy. The executive functions were evaluated using the Frontal Systems Behavioral Scale (FrSBe), reported by self and informant, and neuropsychological performance tests. Functioning was evaluated by Activities of Daily Living (ADL) and Clinical Dementia Rating Scale (CDR-SOB). The MCI group had generalized deficits in the executive functions. The informant executive functions questionnaire appeared to be associated with performance tests, while self-reporting did not show any correlation. Moreover, executive functions, especially informant reported behavioral scales, seemed to predict functioning.

description: In many environmental and industrial applications, the mass transfer of gases in liquid solvents is a fundamental process during the generation of bubbles for specific purposes or, vice versa, the removal of entrapped bubbles. We address the growth dynamics of a trapped slug bubble in a vertical glass cylinder under a water barrier. In the studied process, the ambient air atmosphere is replaced by a CO$_2$ atmosphere at the same or higher pressure. The asymmetric exchange of the gaseous solutes between the CO$_2$-rich water barrier and the air-rich bubble always results in net bubble growth. We refer to this process as solute exchange. The dominant transport of CO$_2$ across the water barrier is driven by a combination of diffusion and convective dissolution. The experimental results are compared to and explained with a simple numerical model, with which the underlying mass transport processes are quantified. Analytical solutions that accurately predict the bubble growth dynamics are subsequently derived. The effect of convective dissolution across the water layer is treated as a reduction of the effective diffusion length, in accordance with the mass transfer scaling observed in laminar or natural convection. Finally, the binary water-bubble system is extended to a ternary water-bubble-alkane system. It is found that the alkane (n-hexadecane) layer bestows a buffering (hindering) effect on bubble growth and dissolution. The resulting growth dynamics and underlying fluxes are characterised theoretically.

description: Racial disparities in US drug arrest rates have been observed for decades, but their causes and policy implications are still contested. Some have argued that the disparities largely reflect differences in drug use between racial groups, while others have hypothesized that discriminatory enforcement policies and police practices play a significant role. In this work, we analyze racial disparities in the enforcement of marijuana violations in the US. Using data from the National Incident-Based Reporting System (NIBRS) and the National Survey on Drug Use and Health (NSDUH) programs, we investigate whether marijuana usage and purchasing behaviors can explain the racial composition of offenders in police records. We examine potential driving mechanisms behind these disparities and the extent to which county-level socioeconomic factors are associated with corresponding disparities. Our results indicate that the significant racial disparities in reported incidents and arrests cannot be explained by differences in marijuana days-of-use alone. Variations in the location where marijuana is purchased and in the frequency of these purchases partially explain the observed disparities. We observe an increase in racial disparities across most counties over the last decade, with the greatest increases in states that legalized the use of marijuana within this timeframe. Income, high school graduation rate, and rate of employment positively correlate with larger racial disparities, while the rate of incarceration is negatively correlated. We conclude with a discussion of the implications of the observed racial disparities in the context of algorithmic fairness.

description: A new crystal chemical method was used to calculate the sign and strength not only of the nearest-neighbor (NN)interactions, but also of the next-nearest-neighbor (NNN) ones in tetragonal compounds Zn2(VO)(PO4)2 (I),(VO)(H2PO4)2 (II), (VO)SiP2O8 (III), (VO)SO4 (IV), (VO)MoO4 (V), Li2(VO)SiO4 (VI) and Li2(VO)GeO4 (VII) with similar sublattices of V4+ ions on the basis of the room-temperature structural data. The reason for difference between respective magnetic interactions characteristics of these compounds was established. It is shown that the characteristic feature of these compounds is a strong dependence of the strength of magnetic interactions and the magnetic moments ordering type on slight displacements of XO4 (X = P, Mo, Si or Ge) groups even without change of the crystal symmetry. In addition to extensively studied square lattice, other specific geometrical configurations of V4+ were discovered. These configurations can result in frustration of magnetic interactions, namely linear chains along the c-axis with competing nearest- and next-to-nearest-neighbor interactions; rectangular (in I) and triangular (in II-VII) lattices with non-equivalent nearest-to-neighbor interactions, which can be also considered as n-leg ladders; one extra square lattice in the ab-plane with longer range interactions. It was concluded that virtually all magnetic interactions in these compounds were frustrated.

description: Research over the past 25 years has led to the view that the rich tapestry of present-day cosmic structure arose during the first instants of creation, where weak ripples were imposed on the otherwise uniform and rapidly expanding primordial soup. Over 14 billion years of evolution, these ripples have been amplified to enormous proportions by gravitational forces, producing ever-growing concentrations of dark matter in which ordinary gases cool, condense and fragment to make galaxies. This process can be faithfully mimicked in large computer simulations, and tested by a variety of observations that probe the history of the Universe starting from just 400,000 yr after the Big Bang.

description: We study the general connectivity distribution functions for growing networks with preferential attachment of fractional power, $Π_{i} \propto k^α$, using the Simon's method. We first show that the heart of the previously known methods of the rate equations for the connectivity distribution functions is nothing but the Simon's method for word problem. Secondly, we show that the case of fractional $α$ the $Z$-transformation of the rate equation provides a fractional differential equation of new type, which coincides with that for PA with linear power, when $α= 1$. We show that to solve such a fractional differential equation we need define a transidental function $Υ(a,s,c;z)$ that we call {\it upsilon function}. Most of all previously known results are obtained consistently in the frame work of a unified theory.

description: Long-slit spectra have been obtained with the Keck telescope for a sample of 11 early-type galaxies covering a wide range in luminosity and hence mass. Rotation velocity and velocity dispersions, together with 19 Lick line-strength gradients have been measured, to, on average, two effective radii. Stellar population models have been used to derive ages, metallicities and alpha/Fe abundances along the radius. We find that line-strength gradients are due, mainly, to variations of the total metallicity with the radius. We also find both, positive and negative, although small, variations in the [alpha/Fe] ratio with radius. We do not find a correlation between the metallicity and the [alpha/Fe] gradients, and the local metallicity is not correlated with the local velocity dispersion for all the galaxies of our sample, which rules out scenarios where the delay in the onset of the galactic winds is the only mechanism producing the metallicity gradients. We found that metallicity gradients are correlated with the shape of the isophotes and the central mean age and metallicity of the galaxies, for galaxies younger than ~10 Gyr. We show that the correlation between the gradients and the central values is not due to the correlation of the errors and indicates that the same process that shaped the gradient, also modified the structural parameters of the galaxies and triggered star formation in their centres. This strongly supports the merger scenario for the formation of these systems, where the degree of dissipation during those mergers increases as the mass of the progenitor galaxies decreases. Finally, we also find a dichotomy in the plane grad[alpha/Fe]-[alpha/Fe] between galaxies with velocity dispersions below and above ~200 km/s, which requires confirmation with larger samples.

description: Σκοπός της μεταπτυχιακής εργασίας ήταν η μελέτη του είδους του πολέμου που διεξάγεται στην Συρία την περίοδο 2011 μέχρι το τέλος του 2017. Αναλυτικά, η θέση τη εργασίας αυτής είναι ότι ο συριακός εμφύλιος πόλεμος έχει δύο φάσεις. Στο πρώτο στάδιο μελετάει την διεξαγωγή ενός συγκεκριμένου είδους πολέμου από τις ΗΠΑ και την Ρωσία, τον ‘πόλεμο δια αντιπροσώπων’. Στο δεύτερο στάδιο ασχολείται με την διεξαγωγή ‘συμβατικού πολέμου’ από τις δύο Μ. Δυνάμεις. Εδώ θα εξετασθεί η επέμβαση με στρατεύματα υπό τις δικές τους σημαίες προκυμμένου να μεταβάλουν τις ισορροπίες στο πεδίο της μάχης. Τέλος, θα αναλύσω τις συνέπειες και τους κινδύνους που παράγει αυτή η εμπλοκή. Για αυτό, κατά την διάρκεια όλης της εργασίας, θα επιλέξω συγκεκριμένες μάχες, εξελίξεις και διπλωματικές προσπάθειες που φωτίζουν την οπτική αυτή.
description: The aim of the present thesis was the study of the kind of war that is being conducted in Syria in the period 2011 to the end of 2017. Specifically, the scope of this thesis is that the Syrian civil war has two stages. In the first phase, I am studying the conduct of a certain kind of war by the United States and Russia, ‘a proxy war’. In the second phase we can observe that the two Great Powers are engaged in a ‘conventional warfare’. Here I will examine the intervention with troops under their own flags, that are designed to change the balance on the battlefield. Finally, I will analyze the implications and risks of this involvement. That is why, during the whole of my thesis, I will choose specific battles, developments and diplomatic efforts that brighten this scope.

description: Amplitude demodulation is a classical operation used in signal processing. For a long time, its effective applications in practice have been limited to narrowband signals. In this work, we generalize amplitude demodulation to wideband signals. We pose demodulation as a recovery problem of an oversampled corrupted signal and introduce special iterative schemes belonging to the family of alternating projection algorithms to solve it. Sensibly chosen structural assumptions on the demodulation outputs allow us to reveal the high inferential accuracy of the method over a rich set of relevant signals. This new approach surpasses current state-of-the-art demodulation techniques apt to wideband signals in computational efficiency by up to many orders of magnitude with no sacrifice in quality. Such performance opens the door for applications of the amplitude demodulation procedure in new contexts. In particular, the new method makes online and large-scale offline data processing feasible, including the calculation of modulator-carrier pairs in higher dimensions and poor sampling conditions, independent of the signal bandwidth. We illustrate the utility and specifics of applications of the new method in practice by using natural speech and synthetic signals.

description: We show the existence of a critical endpoint in the phase diagram of unzipping of an adsorbed double-stranded (ds) polymer like DNA.

description: The similarity renormalization group (SRG) is based on unitary transformations that suppress off-diagonal matrix elements, forcing the hamiltonian towards a band-diagonal form. A simple SRG transformation applied to nucleon-nucleon interactions leads to greatly improved convergence properties while preserving observables, and provides a method to consistently evolve many-body potentials and other operators.

description: Self-duality is a very important concept in the study and applications of topological solitons in many areas of Physics. The rich mathematical structures underlying it lead, in many cases, to the development of exact and non-perturbative methods. We present a generalization of the Yang-Mills-Higgs system by the introduction of scalar fields assembled in a symmetric and invertible matrix h of the same dimension as the gauge group. The coupling of such new fields to the gauge and Higgs fields is made by replacing the Killing form, in the contraction of the group indices, by the matrix h in the kinetic term for the gauge fields, and by its inverse in the Higgs field kinetic term. The theory is conformally invariant in the three dimensional space R^3. An important aspect of the model is that for practically all configurations of the gauge and Higgs fields the new scalar fields adjust themselves to solve the modified self-duality equations. We construct solutions using a spherically symmetric ansätz and show that the 't Hooft-Polyakov monopole becomes a self-dual solution of such modified Yang-Mills-Higgs system. We use an ansätz based on the conformal symmetry to construct vacuum solutions presenting non-trivial toroidal magnetic fields.

description: Stability of homogeneous precession of spin due to parametric excitation of spin waves is considered as the explanation of the "catastrophic relaxation", that is observed in the superfluid 3He-B. It is shown, that at sufficiently low temperatures homogeneous precession of spin becomes unstable (Suhl instability). At zero temperature increments of growth for all spin wave modes are found. Estimation of the temperature of transition to the unstable state is made.

description: We study the emergence of color superconductivity in the theory of the strong interaction at supranuclear densities. To this end, we follow the renormalization group (RG) flow of dense strong-interaction matter with two massless quark flavors from the fundamental quark and gluon degrees of freedom at high energies down to the non-perturbative low-energy regime which is found to be governed by the dynamical formation of diquark states. With the strong coupling at the initial RG scale as the only input parameter, we compute the (chirally symmetric) scalar diquark condensate and analyze its scaling behavior over a wide range of the quark chemical potential. Approximations entering our computations are critically assessed. Since our approach naturally allows us to study the scale dependence of couplings, we also monitor the strength of couplings appearing in low-energy models of dense strong-interaction matter. The observed dependence of these couplings on the quark chemical potential may help to amend model studies in the future. Finally, we estimate the speed of sound of dense QCD matter. Our results indicate that the speed of sound exceeds the value of the noninteracting quark gas at high densities and even increases as the density is decreased, across a wide range, suggesting the existence of a maximum at supranuclear densities.
