description: Ο σκοπός αυτής της μελέτης ήταν να ερευνηθεί η επίδραση ενός ολιστικού προγράμματος φυσικής κατάστασης σύντομης διάρκειας και με μικρή εβδομαδιαία συχνότητα σε δείκτες φυσικής κατάστασης (ταχύτητα 10 και 30 μέτρα, ευκινησία, αλτικότητα) σε υψηλού επιπέδου νεαρούς ποδοσφαιριστές. Στην έρευνα συμμετείχαν 28 ποδοσφαιριστές δύο επαγγελματικών ομάδων που αγωνιζόταν στα αναπτυξιακά πρωταθλήματα κατηγορίας κ19 (κάτω των 19 ετών). Οι παίκτες χωρίστηκαν σε 2 γκρουπ: γκρουπ παρέμβασης (EG , n=15) και control γκρουπ (CG, n=13). Tο πρόγραμμα παρέμβασης είχε διάρκεια 8 εβδομάδες με συχνότητα 2 φορές την εβδομάδα. Οι επιδόσεις των συμμετοχόντων στην ταχύτητα 10 και 30 μέτρα, στο άλμα με αντίθετη προπαρασκευαστική κίνηση (CMJ), στο άλμα από ημικάθισμα (SJ), στην ευκινησία (Illinoisagility τεστ, Αrrowhead agility τεστ). Μετρήθηκαν πριν και μετά την εφαρμογή του προγράμματος παρέμβασης. Τα αποτελέσματα έδειξαν ότι στις επιδόσεις των συμμετοχόντων στους δείκτες φυσικής κατάστασης που αξιολογήθηκαν δεν παρατηρήθηκε βελτίωση (P>0.05). Συμπερασματικά,από τα αποτελέσματα της μελέτης φάνηκε ότι το ολιστικό πρόγραμμα παρέμβασης με μικρή συχνότητα και διάρκεια δεν βελτίωσε την ικανότητα των συμμετοχόντων στους δείκτες που αξιολογήθηκαν. Το αποτέλεσμα αυτό μπορεί να εξηγηθεί από την μικρή συχνότητα, τη σύντομη διάρκεια και την ένταση (χωρίς εξωτερικές επιβαρύνσεις).
description: The aim of this study was to investigate the effect of a short duration and low weekly frequency holistic program in physical condition rates (10 meters speed, 30 meters speed, agility, jumps) of elite youth soccer players. Twenty-eight elite youth soccer players, members of two professional clubs, playing in the u19 developmental championship participated in this study. They were divided in 2 groups: the intervention group (EG, n=15) and the control group (CG, n=13). The duration of the intervention program was 8 weeks with a frequency of twice per week. The performance of the participants in the 10 meters and 30 meters speed, countermovement jump (CMJ), squat jump (SJ) and agility (Illinois agility test, Arrowhead agility test) was measured prior and after the implementation of the intervention program. Results have pointed out that the performance of the participants in the physical condition rates under evaluation has indicated no improvement (P>0,05). Summarizing, the outcome of the study bespoke that the low frequency and duration intervention program did not enhance the ability of the participants in the evaluated rates. Such as outcome can be interpreted by the short duration, the low frequency and low intensity.

description: In this letter, we construct a model based on a flipped SU(5) partial grand unified theory, within the framework of the Randall-Sundrum (RS1) proposal. Breaking of $\widetilde{SU}(5)$ is achieved using a bulk scalar field in the \textbf{10} of SU(5), $Φ$, which gains a vacuum expectation value $\left< Φ\right> \sim 3 \times 10^{15}$ GeV. We are able to retain the successes of the flipped SU(5) phenomenology, namely the elimination of the doublet-triplet splitting problem and the confinement of all fields to the smallest (\textbf{1}, $\mathbf{\bar{5}}$, and \textbf{10}) representations of SU(5). We derive the beta functions, and point out some constraints on bulk matter content implied by the runnings (and positivity) of the five dimensional coupling. Finally, we comment on baryon decay and show the fine-tuning problem required to prevent an exponentially short proton lifetime.

Coevolution of Supermassive Black Holes and Circumnuclear Disks

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: We propose a new evolutionary model of a supermassive black hole (SMBH) and a circumnuclear disk (CND), taking into account the mass-supply from a host galaxy and the physical states of CND. In the model, two distinct accretion modes depending on gravitational stability of the CND play a key role on accreting gas to a SMBH. (i) If the CMD is gravitationally unstable, energy feedback from supernovae (SNe) supports a geometrically thick, turbulent gas disk. The accretion in this mode is dominated by turbulent viscosity, and it is significantly larger than that in the mode (ii), i.e., the CMD is supported by gas pressure. Once the gas supply from the host is stopped, the high accretion phase ($\sim 0.01- 0.1 M_{\odot} {\rm yr}^{-1}$) changes to the low one (mode (ii), $\sim 10^{-4} M_{\odot} {\rm yr}^{-1}$), but there is a delay with $\sim 10^{8}$ yr. Through this evolution, the gas-rich CND turns into the gas poor stellar disk. We found that not all the gas supplied from the host galaxy accrete onto the SMBH even in the high accretion phase (mode (i)), because the part of gas is used to form stars. As a result, the final SMBH mass ($M_{\rm BH,final}$) is not proportional to the total gas mass supplied from the host galaxy ($M_{\rm sup}$); $M_{\rm BH,final}/M_{\rm sup}$ decreases with $M_{\rm sup}$.This would indicate that it is difficult to form a SMBH with $\sim 10^{9} M_{\odot}$ observed at high-$z$ QSOs. The evolution of the SMBH and CND would be related to the evolutionary tracks of different type of AGNs.

description: Hypermassive neutron stars (HMNSs) are equilibrium configurations supported against collapse by rapid differential rotation and likely form as transient remnants of binary neutron star mergers. Though HMNSs are dynamically stable, secular effects such as viscosity or magnetic fields tend to bring HMNSs into uniform rotation and thus lead to collapse. We simulate the evolution of magnetized HMNSs in axisymmetry using codes which solve the Einstein-Maxwell-MHD system of equations. We find that magnetic braking and the magnetorotational instability (MRI) both contribute to the eventual collapse of HMNSs to rotating black holes surrounded by massive, hot accretion tori and collimated magnetic fields. Such hot tori radiate strongly in neutrinos, and the resulting neutrino-antineutrino annihilation could power short-hard GRBs.

Fractional parts of powers and related topics
Creators: name: Bennett, Michael A.
Publisher: name: University of British Columbia
Year: 2008

description: In this thesis, we employ a variety of explicit approximations to tackle some problems in Diophantine analysis. We are generally concerned with constructing rational function approximations to certain polynomials and to the exponential and other related functions. From these systems, we deduce arithmetic information about the original problem. Chapter 0 is an introduction to the field and contains background information and known results from the literature. The situation for algebraic numbers in general is briefly surveyed. In Chapter 1, we utilize Pade approximation in the manner of F. Beukers to generalize and sharpen results of Beukers, D. Easton and G. Xu about lower bounds for fractional parts of powers of rationals. Some theorems of a "semi-effective" nature are discussed and density results for certain constructed sets are proved. In Chapter 2, we utilize Euler-Maclaurin summation to describe the content of Pade-type approximants to the binomial function. These results form the basis for the afore-mentioned improved bounds. Through similar techniques to those employed in Chapter1 we derive lower bounds upon fractional parts of values of the exponential at integers. These are given in Chapter 4. Chapter 3 contains an application of the above theory to additive number theory, in particular to Waring's problem and related questions about additive bases. The Hardy-Littlewood-Vinogradrov circle method is used with a theorem from Chapter 1 to prove a version of the Ideal Waring problem with restricted summands.
Renormalization of the C2HDM with FeynMaster 2

description: We present the one-loop electroweak renormalization of the CP-violating 2-Higgs-Doublet Model with softly broken $\mathbb{Z}_2$ symmetry (C2HDM). The existence of CP violation in the scalar sector of the model leads to a quite unique process of renormalization, since it requires the introduction of several non-physical parameters. The C2HDM will thus have more independent counterterms than independent renormalized parameters. As a consequence, different combinations of counterterms can be taken as independent for the same set of independent renormalized parameters. We compare the behaviour of selected combinations in specific NLO processes, which are assured to be gauge independent via a simple prescription. FeynMaster 2 is used to derive the Feynman rules, counterterms and one-loop processes in a simultaneously automatic and flexible way. This illustrates its use as an ideal tool to renormalize models such as the C2HDM and investigate them at NLO.

description: This manifesto presents a philosophical and technological alignment proposal between the XChronos project and the OpenAI Academy. Rooted in ontological idealism and temporal epistemology, XChronos introduces symbolic units of time — Crônons, Hexacrônons, and Metachronos — to explore time not as a neutral backdrop but as a lived and conscious journey.

The document invites OpenAI to recognize XChronos not merely as a platform, but as a living framework integrating symbolic logic, open science, and artificial intelligence. Through public publications, educational integration, and conceptual innovation, XChronos aims to co-create a future where AI enhances meaning, presence, and time awareness.

Authored by Jaconaazar Souza Silva, an audiovisual lab technician at IFB (Instituto Federal de Brasília), this piece reflects the convergence of peripheral vision, philosophical structure, and technological imagination.

description: This list of potential Adverse Events of Special Interest (AESI) that could follow vaccines to prevent Marburg Virus Disease (MVD) was developed based on criteria established by the Safety Platform for Emergency Vaccines (SPEAC), which include: 

A known association with immunization or a specific vaccine platform.

The occurrence during wild-type disease due to viral replication and/or immunopathogenesis.

A theoretical association derived from animal models. 

Special populations, including pregnant women, children, adolescents, and immunosuppressed individuals, may experience an increased frequency and severity of any of the AESIs listed as relevant to all populations. There are also specific AESI that are of particular relevance to special populations, and these are listed according to the population. It is important to note that children, pregnant women and immunocompromised individuals may also have increased severity of expected local and systemic reactogenicity, as well as unexpected autoimmune conditions. 

Note: Several AESI highlighted in gray are included due to their presence in MVD itself but are only relevant for possible live-attenuated vaccines (e.g. live attenuated MARV, measles vector, etc). These are not recommended to include for all platforms, e.g. Adenovirus-vectored vaccines.

This list is based on available data for MVD vaccines, for consideration in deployment of investigational MVD vaccines in response to the 2024 outbreak in Rwanda.  Adaptions may be needed depending on the application.

description: We have calculated numerically the gap exponent of the anisotropic Heisenberg model in the presence of the transverse magnetic field. We have implemented the modified Lanczos method to obtain the excited states of our model with the same accuracy of the ground state. The coefficient of the leading term in the perturbation expansion diverges in the thermodynamic limit (N --> infinity). We have obtained the relation between this divergence and the scaling behaviour of the energy gap. We have found that the opening of gap in the presence of transverse field scales with a critical exponent which depends on the anisotropy parameter (Delta). Our numerical results are in well agreement with the field theoretical approach in the whole range of the anisotropy parameter, -1 < Delta < 1.

description: The outburst and proliferation of the COVID-19 pandemic, together with the subsequent social distancing measures, have raised massive challenges in almost all domains of public and private life around the globe. The stay-at-home movement has pushed the news audiences into social networks, which, in turn, has become the most prolific field for receiving and sharing news updates, as well as for public expression of opinions, concerns and feelings about the pandemic. Public opinion is a critical aspect in analysing how the information and events impact peoples lives, and research has shown that social media data may be promising in understanding how people respond to health risks and social crisis, which are the feelings they tend to share and how they are adapting to unforeseen circumstances that threaten almost all societal spheres. This paper presents results from a social media analysis of 61532 news headlines posted by the major daily news outlet in Portugal, Sic Noticias, on Facebook, from January to December 2020, focusing on the issues attention cycle and audiences emotional response to the COVID news outburst. This work adds to the emergent body of studies examining public response to the coronavirus pandemic on social media data.

description: Ο γερμανικός ρομαντισμός υπήρξε έμπνευση για πολλούς καλλιτέχνες, ακαδημαϊκούς και συγγραφείς με την πάροδο του χρόνου. Η παρούσα μελέτη ασχολείται με το θέμα της φύσης και προσπαθεί να δημιουργήσει μια σύνδεση μεταξύ του γερμανικού ρομαντισμού και των σημερινών περιβαλλοντικών οργανώσεων. Αυτή η σύνδεση μπορεί στην πραγματικότητα να μην αποδεικνύεται εύκολα, αλλά δεν μπορεί κανείς να αρνηθεί το γεγονός ότι αυτές οι ιδέες γύρω από την εξιδανικευμένη φύση έχουν ταξιδέψει και έχουν διαμορφώσει περαιτέρω ιδέες και απόψεις, και σε ορισμένες περιπτώσεις, ολόκληρες γενιές. Αλλά για να είναι σαφέστερη αυτή η σύνδεση, είναι λογικό να πραγματοποιηθεί ένα μακρύ ταξίδι μέσω του ευρωπαϊκού, γερμανικού, αγγλικού και αμερικανικού ρομαντισμού, που είναι ένα σημαντικό σημείο αναφοράς. Οι περιβαλλοντικές θεωρίες καθώς και τα περιβαλλοντικά κινήματα του 20ου και του 21ου αιώνα εμπνεύστηκαν από αυτές τις ιδέες και με τη σειρά τους διαμόρφωσαν τις βασικές ιδέες καθώς και τα ιδανικά πολλών περιβαλλοντικών οργανώσεων και ανεξάρτητων ακτιβιστών. Με αυτόν τον τρόπο καθίσταται σαφέστερο ότι οι εξιδανικευμένες εικόνες της φύσης από τους Novalis, Eichendorff και Caspar David Friedrich, όπως και η ιδέα του υψηλού, εξακολουθούν να υπάρχουν και να εμπνέουν.
description: German romanticism has served as an inspiration for many artists, academics and writers over time. The present study deals with the topic of nature and tries to establish a connection between German romanticism and today's environmental organizations. This connection may not actually be proven, but one cannot refuse to see that these ideas about the idealized nature have travelled around and have shaped further ideas and views, and in some cases, entire generations. But in order for this connection to be clearer, it makes sense to take a long journey through European, German, English and American romanticism, which is an important starting point. Environmental theories as well as environmental movements of the 20th and 21st centuries were inspired by these ideas and in turn shaped the core ideas and ideals of many environmental organizations and independent activists. In this way it is made clearer that the idealized nature pictures from Novalis, Eichendorff and Caspar David Friedrich, as well as the idea of the sublime, are still present.

Η εξέταση έγινε μετά από προσαρμογή των συνθηκών ανάλυσης σε υγροχρωματογραφική στήλη που μπορεί να χρησιμοποιηθεί τόσο σε σύστημα UHPLC, όσο και συμβατικό σύστημα HPLC. Η μέθοδος εξετάστηκε ως προς την επαναληψιμότητά της, αλλά και ως προς την επίδραση σειράς αναλυτικών παραμέτρων που σχετίζονται με την ανθεκτικότητά της. Τα ευρήματα έδειξαν ότι η μέθοδος είναι επαναλήψιμη και σχετικά ανθεκτική. Οι προτεινόμενες παρεμβάσεις στο πρωτόκολλο, εφόσον υιοθετηθούν από την αρμόδια Τεχνική Επιτροπή ISO, αναμένεται να οδηγήσουν στην αισθητή μείωση του χρόνου προετοιμασίας και ανάλυσης του δείγματος, με βελτιωμένη ευαισθησία κατά την ανίχνευση των ενώσεων-στόχων. Το τροποποιημένο πρωτόκολλο εφαρμόστηκε στη συνέχεια σε περιορισμένη σειρά δειγμάτων παρθένου ελαιολάδου αποθηκευμένων στο σκοτάδι και σε διαφορετική θερμοκρασία για τον έλεγχο της διαγνωστικής του αξίας.
description: In the present work, a series of analytical parameters of the ISO 29841:2012 protocol for the determination of degradation products of chlorophyll a and a’ (pheophytin a, a’ and pyropheophytin) were examined considering their possible effect on its performance. The examination was carried out after adjusting the conditions of analysis to a liquid chromatographic column that can be used in both UHPLC and conventional HPLC systems. The method was examined for repeatability and robustness. The findings have shown that the method is repeatable and relatively robust. Proposed modifications in the protocol, if adopted by the ISO relevant Technical Committee, are expected to lead to a significant reduction in sample preparation and analysis time, and improved sensitivity in the detection of the target compounds. The modified protocol was then applied to a limited number of virgin olive oil samples stored in the dark at a different temperature to examine its diagnostic potential.

description: In this paper, a protocol is proposed in which energy extraction from local vacuum states is possible by using quantum measurement information for the vacuum state of quantum fields. In the protocol, Alice, who stays at a spatial point, excites the ground state of the fields by a local measurement. Consequently, wavepackects generated by A' measurement propagate the vacuum to spatial infinity. Let us assume that Bob stays away from Alice and fails to catch the excitation energy when the wavepackets pass in front of him. Next Alice announces her local measurement result to Bob by classical communication. Bob performs a local unitary operation depending on the measurement result. In this process, positive energy is released from the fields to Bob's apparatus of the unitary operation. In the field systems, wavepackets are generated with negative energy around Bob's location. Soon afterwards, the negative -energy wavepackets begin to chase after the positive-energy wavepackets generated by Alice and form loosely bound states.

The discrete velocity method in plasma physics
Creators: name: Irwin, Andrew J.
Publisher: name: University of British Columbia
Year: 2008

description: The objective of this thesis is to apply a discrete velocity model to kinetic theory problems in plasma physics. Numerical approaches commonly used in kinetic theory are described and compared with the discrete velocity models. The discrete Boltzmann equation (DBE) is a commonly used discrete velocity method for problems in rarefied gas dynamics and is adapted for plasma physics in this thesis. The Boltzmann equation is used to model the relaxation to equilibrium of a pure electron plasma. The first of two problems studied is the relaxation of test particles in a Maxwellian bath. This is a linear version of the second problem and serves as a test experiment for the method and the computer code. The second problem is the nonlinear relaxation of an anisotropic velocity distribution of electrons due to self-collisions. This physical situation arises in many natural phenomena, such as atmospheric and space plasmas, as well as in many laboratory investigations. Pure electron plasmas have been the subject of many experiments, including studies of time dependent transport properties and studies of the relaxation of anisotropic velocity distributions. The Fokker-Planck and Boltzmann equations are commonly used as the theoretical starting point for studies of plasmas.

description: Optical time series photometry of the short period magnetic white dwarf + probable brown dwarf binary SDSS 121209.31+013627.7 reveals pulse-like variability in all bands from i' to u', peaking at u'. These modulations are most likely due to a self-eclipsing accretion hot spot on the white dwarf, rotating into view every 88.43 minutes. This period is commensurate with the radial velocity period determined by Schmidt et al. 2005 of ~90 minutes, and consistent with the rotation period of the accretor being equal to the binary orbital period. We combine our observations with those recently published by Koen and Maxted 2006 to provide an accurate ephemeris. We also detect the system in X-rays with Swift, and estimate the accretion rate at ~1x10^-13Msun per year. We suggest that SDSS1212 is most likely a magnetic cataclysmic variable in an extended state of very low accretion, similar to the well-studied Polar EF Eri. Alternatively, the putative brown dwarf is not filling its Roche Lobe and the system is a detached binary in which the white dwarf is efficiently accreting from the wind of the secondary. Six such post-common envelope, ``pre-Polar'' systems - termed ``low accretion rate Polars (LARPs)'' by Schwope et al. 2002 - have previously been identified through optical cyclotron emission lines. Cyclotron emission from SDSS1212 has recently been detected in the near-IR Debes et al. 2006 but, if detached, it would be the first ``LARP'' with a probably sub-stellar secondary. It is unclear whether an L-dwarf wind is strong enough to provide the measured accretion rate. We suggest further observations to distinguish between the Roche Lobe over-flow and wind accretion scenarios.

Now we are facing another big problem that if we let it grow it might even equalize the lack of knowledge. Ely et al. [1] have found that physicians spend an average of 2 min or less in seeking an answer, while Hersh et al. [2] have found that it takes more than 30 min on average for a health care professional to search for an answer. As a result many clinical questions go unanswered. “Better be ignorant of a matter than half know it.” Publilius Syrus said. So we know as a fact that efficient searching has gone far from the reach of plain human abilities. Thus, we need Question Answering (QA) Systems, which eventually will do the hard work of answering in a matter of few minutes. Question Answering is a multi-layered problem. In this work we will try to analyze the potential of re-ranking results retrieved from Information Retrieval techniques. More specifically the re-ranking is performed by machine learning models using word embedding that try to take into account the context of the sentences.
description: Καθόλη την διάρκεια της Ιστορίας η δυνατότητα της αποτύπωσης της πληροφορίας και της πρόσβασης σε αυτήν, προσέφερε στην επιστήμη πρόοδο. Στην αρχή η πληροφορία ήταν προσβάσιμη μέσω των βιβλίων και των βιβλιοθηκών. Μέχρις ότου έγινε η εμφάνιση του διαδικτύου και η γνώση έγινε ποιο προσιτή από ποτέ. Τώρα αντιμετωπίζουμε ένα άλλο πρόβλημα, το οποίο αν αμελήσουμε θα υπερνικήσει ακόμα και αυτό της έλλειψης πληροφορίας. Ο Ely και λοιποί. [1] βρήκαν ότι οι γιατροί ξοδεύουν κάτω των 2 λεπτών κατά μέσο όρο για να πάρουν μια απάντηση, ενώ ο Hersh και λοιποί [2] βρήκαν ότι επαγγελματίες του χώρου υγείας χρειάζονται πάνω από 30 λεπτά κατά μέσο όρο για να βρούν μια απάντηση. Κατά συνέπεια πολλές κλινικές ερωτήσεις μένουν αναπάντητες. «Καλύτερη η άγνοια από την ημιμάθεια.» είπε ο Publilius Syrus. Οπότε είναι πλέον γεγονός ότι η αναζήτηση πληροφορίας με απλώς ανθρώπινες δυνατότητες είναι πέραν της αποτελεσματικής. Για αυτό υπάρχει η ανάγκη για συστήματα Απάντησης Ερωτήσεων (ΑΕ). Τα οποία εν τέλη θα κάνουν την σκληρή δουλειά της αναζήτησης απαντήσεων θέμα λίγων λεπτών. Η Αναζήτηση Απαντήσεων είναι ένα πολυδιάστατο πρόβλημα. Σε αυτό το έργο θα προσπαθήσουμε να αναλύσουμε τις δυνατότητες της ανακατάταξης των αποτελεσμάτων προερχόμενων από τεχνικές Ανάκτησης Πληροφοριών (ΑΠ). Συγκεκριμένα η ανακατάταξη πραγματοποιείτε από μοντέλα Μηχανικής Μαθήσεως χρησιμοποιώντας embeddings λέξεων που προσπαθούν να λάβουν υπόψιν τα συμφραζόμενα των προτάσεων.

description: To combat insufficient space for planting food, insecurity and to ensure the availability of adequate food nutrients crops are grown in different media. In this study, three yam varieties: Dioscorea alata, Dioscorea rotundata, and Dioscorea cayennesis were sourced from a local market in Ebonyi State and divided into two portions. One portion was processed into flour and was evaluated the second portion of the yam was planted in two different planting media: soil and bag and their nutrient composition was assessed. The result generated the mineral composition of Mg, P, K of the yam samples were better improved and retained when planted in direct soil than in bags, except DR in which the P content was better retained in DRB than DRS. The mineral composition of calculi is retained better when planted in bags than in direct soil except in DR.

description: Sum rules for the energy levels of a hyperfine multiplet in a constant uniform magnetic field is presented. It is found that for any values of the electron angular moment and the nuclear spin there are certain linear combinations of energy levels which do not depend on the magnetic field and can be used to determine the unperturbated hfs separation in the presence of perturbing magnetic field. It is also demonstrated that there are other linear combinations which are linear with the external magnetic field and hence can be used to determine bound values of the electron and nuclear magnetic moments. The accuracy of the approximation within which the result is valid is also discussed.

description: The effect of quantum and thermal fluctuations on the phase diagram of spin-2 BECs is examined. They are found to play an important role in the nematic part of the phase diagram, where a mean-field treatment of two-body interactions is unable to lift the accidental degeneracy between nematic states. Quantum and thermal fluctuations resolve this degeneracy, selecting the uniaxial nematic state, for scattering lengths $a_4>a_2$, and the square biaxial nematic state for $a_4

description: This paper is a review of the up-to-date literature regarding the epidemiological characteristics of the chronic kidney disease related anemia and its therapeutic protocols in Greece. Anemia is an important morbidity factor in patients with CKD because of its correlation with a reduction of the life quality and an increase in cardiovascular disease, number of days of hospitalisation, cognitive disorders and the mortality rate. More specifically, the pathophysiology and the causes of the disease are being studied and the epidemiological characteristics in U.S., Asia, Europe and Greece are being reviewed. Moreover, there is an analysis of the clinical treatment of CKD in Greece, with regard to pharmacological and non pharmacological treatments as well as their surveillance according to the Greek guidelines. Furthermore, the topic of the future challenges needing to be dealt with for the sake of unfulfilled medical needs is being examined. Finally, the evidence deriving from the literature concerning the clinical managment cost is being analysed and the clinical value of the guidelines is being emphasized. Part of the paper consists of a questionaire about the epidemiological, clinical and financial data of the chronic kidney disease related anemia in Greece, which is adressed to a Key Opinion Leader (KOL).

description: We have studied charge transport through individual Borromean Ring complexes, both with and without anchor groups, in gated double barrier tunneling junctions (DBTJs) formed using the electrical breakjunction technique on gold nanowires. While common single molecule device characteristics can be observed with either form of the Borromean Rings, the complexes with anchor groups show strong rectification of conduction in a relatively high percentage of samples. We present our data along with a simple model underlining the mechanism by which the arrangement and composition of the weakly bonding anchor groups attached to the electroactive element may promote a device configuration resulting in rectification.

description: The present study examines the issue of the reform of the calender in the Or-thodox Church. It commences with a scientific overview of the concept of time and the development of various calendars. Then the question of the calender reform is studied diachronically, from the early Christian period to the present, focusing on the basic canonico-liturgical aspects of the issue, especially with respect to the computation of the date of Easter and the quest for the common celebration of this great feast. Finally, various implications of the topic that continue to be pertainant are discussed.

description: A search for a fourth family at the LHC is presently a low priority, but we argue that an effective search can be conducted early with only a few inverse femtobarns of data. We discuss a method based on invariant masses of single jets for identifying the $W$'s originating from heavy quark decays. This can significantly increase signal to background in the reconstruction of the $t'$ mass. We also study the various types of physics that can impact the background estimate, most notably higher order effects, initial state radiation, and models of the underlying event.

description: We study four lines of sight that probe the transition from diffuse molecular gas to molecular cloud material in Taurus. Measurements of atomic and molecular absorption are used to infer the distribution of species and the physical conditions toward stars behind the Taurus Molecular Cloud (TMC). New high-resolution spectra at visible and near infrared wavelengths of interstellar Ca II, Ca I, K I, CH, CH^+, C2, CN, and CO toward HD28975 and HD29647 are combined with data at visible wavelengths and published CO results from ultraviolet measurements for HD27778 and HD30122. Gas densities and temperatures are inferred from C2, CN, and CO excitation and CN chemistry. Our results for HD29647 are noteworthy because the CO column density is 10^{18} cm^{-2} while C2 and CO excitation reveals a temperature of 10 K and density about 1000 cm^{-3}, more like conditions found in dark molecular clouds. Similar results arise from our chemical analysis for CN through reactions involving observations of CH, C2, and NH. Enhanced potassium depletion and a reduced CH/H2 column density ratio also suggest the presence of a dark cloud. The directions toward HD27778 and HD30122 probe molecule-rich diffuse clouds, which can be considered CO-dark gas, while the sight line toward HD28975 represents an intermediate case. Maps of dust temperature help refine the description of the material along the four sight lines and provide an estimate of the distance between HD29647 and a clump in the TMC. An Appendix provides results for the direction toward HD26571; this star also probes diffuse molecular gas.

description: Supersolid is a mysterious and puzzling state of matter whose possible existence has stirred a vigorous debate among physicists for over 60 years. Its elusive nature stems from the coexistence of two seemingly contradicting properties, long-range order and superfluidity. We report computational evidence of a supersolid phase of deuterium under high pressure ($p >800$ GPa) and low temperature (T $

description: Differential privacy is a privacy measure based on the difficulty of discriminating between similar input data. In differential privacy analysis, similar data usually implies that their distance does not exceed a predetermined threshold. It, consequently, does not take into account the difficulty of distinguishing data sets that are far apart, which often contain highly private information. This problem has been pointed out in the research on differential privacy for static data, and Bayesian differential privacy has been proposed, which provides a privacy protection level even for outlier data by utilizing the prior distribution of the data. In this study, we introduce this Bayesian differential privacy to dynamical systems, and provide privacy guarantees for distant input data pairs and reveal its fundamental property. For example, we design a mechanism that satisfies the desired level of privacy protection, which characterizes the trade-off between privacy and information utility.
