description: In the conventional theory of density wave ordering in metals, the onset of spin density wave (SDW) order co-incides with the reconstruction of the Fermi surfaces into small 'pockets'. We present models which display this transition, while also displaying an alternative route between these phases via an intermediate phase with topological order, no broken symmetry, and pocket Fermi surfaces. The models involve coupling emergent gauge fields to a fractionalized SDW order, but retain the canonical electron operator in the underlying Hamiltonian. We establish an intimate connection between the suppression of certain defects in the SDW order, and the presence of Fermi surface sizes distinct from the Luttinger value in Fermi liquids. We discuss the relevance of such models to the physics of the hole-doped cuprates near optimal doping.

description: We construct a certain $\F_2$-valued analogue of the mixed volume of lattice polytopes. This 2-mixed volume cannot be defined as a polarization of any kind of an additive measure, or characterized by any kind of its monotonicity properties, because neither of the two makes sense over $\F_2$. In this sense, the convex-geometric nature of the 2-mixed volume remains unclear. On the other hand, the 2-mixed volume seems to be no less natural and useful than the classical mixed volume -- in particular, it also plays an important role in algebraic geometry. As an illustration of this role, we obtain a closed-form expression in terms of the 2-mixed volume to compute the signs of the leading coefficients of the resultant, which were by now explicitly computed only for some special cases.

description: Atomically thin rhenium disulphide (ReS2) is a member of the transition metal dichalcogenide (TMDC) family of materials characterized by weak interlayer coupling and a distorted 1T structure. Here, we report on the electrical transport study of mono- and multilayer ReS2 with polymer electrolyte gating. We find that the conductivity of monolayer ReS2 is completely suppressed at high carrier densities, an unusual feature unique to monolayers, making ReS2 the first example of such a material. While thicker flakes of ReS2 also exhibit a conductivity dome and an insulator-metal-insulator sequence, they do not show a complete conductivity suppression at high doping densities. Using dual-gated devices, we can distinguish the gate-induced doping from the electrostatic disorder induced by the polymer electrolyte itself. Theoretical calculations and a transport model indicate that the observed conductivity suppression can be explained by a combination of a narrow conduction band and Anderson localization due to electrolyte-induced disorder.

description: A formulation for the automated generation of algorithms via mathematical programming (optimization) is proposed. The formulation is based on the concept of optimizing within a parameterized family of algorithms, or equivalently a family of functions describing the algorithmic steps. The optimization variables are the parameters -within this family of algorithms- that encode algorithm design: the computational steps of which the selected algorithms consists. The objective function of the optimization problem encodes the merit function of the algorithm, e.g., the computational cost (possibly also including a cost component for memory requirements) of the algorithm execution. The constraints of the optimization problem ensure convergence of the algorithm, i.e., solution of the problem at hand. The formulation is described prototypically for algorithms used in solving nonlinear equations and in performing unconstrained optimization; the parametrized algorithm family considered is that of monomials in function and derivative evaluation (including negative powers). A prototype implementation in GAMS is developed along with illustrative results demonstrating cases for which well-known algorithms are shown to be optimal. The formulation is a mixed-integer nonlinear program (MINLP). To overcome the multimodality arising from nonconvexity in the optimization problem, a combination of brute force and general-purpose deterministic global algorithms is employed to guarantee the optimality of the algorithm devised. We then discuss several directions towards which this methodology can be extended, their scope and limitations.

description: We report the first observation of Rabi oscillations in the spin-7/2 ensemble of trivalent gadolinium ions hosted in CaWO$_4$ single crystal. A number of transitions within the lowest electronic multiplet $^8S_{7/2}$ of Gd$^{3+}$ ion are studied using a combination of continuous-wave and pulsed electron paramagnetic resonance spectroscopy. The corresponding Rabi damping curves and the spin coherence times are detected at varying strengths of the microwave field. These data are well reproduced by a theoretical model which accounts for the intrinsic inhomogeneity of the microwave field within the microwave resonator and the magnetic dipole interactions in the diluted spin ensemble. The results indicate that the studied 8-level ground manifold of Gd$^{3+}$ ion can represent an effective three qubit quantum system.
A 100 kJ Pulse Unit for Electromagnetic Forming of Large Area Sheet Metals

description: Magnetoforming of tube or sheet metal parts can significantly extend the range of geometries conceivable with state-of-the-art forming methods. A major advantage is the considerably higher forming speed of the process achievable by using a magnetic piston without inertia. Key for this technology is the development of reliable, long-lifetime, high current pulse power generators able to deliver tens to hundreds of kiloamps of peak current to a mainly inductive load which is highly variable in time during the forming process. A high-current, high energy pulse generator for electromagnetic forming of large area sheet metal has been developed and was taken into operation. Design criteria were reliability and safety for all possible load cases, including short circuits and short-circuiting loads under operation, at nominal peak currents of up to 200 kA and peak pulse energies of up to 100 kJ. In order to comply with the safety requirements, an all-solid-state design has been chosen using high power semiconductor switches for pulse forming instead of ignitrons or spark gaps. Due to constraints concerning space and manageability, the coupling between the load and the pulse forming unit is achieved via a semi-rigid bundle of high voltage cables, allowing an adjustment of the carrier of the forming coil while being electrically connected to each other. We report on the development of a pulse generator for peak currents of 50 kA to up to 200 kA at a pulse width of typically around 100 µs, depending on the load parameters. In order to meet lifetime requirements suitable for industrial applications, the short circuit handling capability of peak currents of up to 450 kA is a major issue in the pulse generator design. A modular 3-branch design of parallel capacitor banks has been adopted to achieve the requirements concerning reliability, lifetime, and short circuit handling. The prototype pulse generator is based upon off-the-shelf devices, including high-current semiconductor switches. First operating results of the commissioning phase of the installation are reported.

description: Electromagnetic compression of tubular profiles with high electrical conductivity is an innovative joining process for lightweight structures. The components are joined using pulsed magnetic fields which apply radial pressures of up to 200 MPa to tubular workpieces, causing a symmetric reduction of the diameter with typical strain rates of up to 10^4 sec^(-1). This process avoids any surface damage of the workpiece because there is no contact between component and forming tool. The strength of electromagnetically formed joints made of aluminum tubes under cyclic loads is essential to establish electromagnetic forming in automotive structures. In the present paper, the quasi-static performance of tubular joints made by electromagnetic compression produced of different mandrel materials will be analyzed as to the influence of process parameters. Therefore, experimental investigations on aluminum tubes (AA6060) joined on mandrels made of different aluminum, copper, and steel alloys were carried out. Furthermore, the behavior of joints with both mandrel and tube made of AA6060 at swelling cyclic loads (R = δ_ min / δ_ max =0) has been evaluated.

description: Dirichlet boundary conditions have been widely used in general relativity. They seem at odds with the holographic property of gravity simply because a boundary configuration can be varying and dynamic instead of dying out as required by the conditions. In this work we report what should be a tension between the Dirichlet boundary conditions and quantum gravitational effects, and show that a quantum-corrected black hole solution of the 1PI action no longer obeys, in the naive manner one may expect, the Dirichlet boundary conditions imposed at the classical level. We attribute the `violation' of the Dirichlet boundary conditions to a certain mechanism of the information storage on the boundary.

description: In the first stage of this work, polycrystalline specimens of AZ31B magnesium alloy have been characterized by uniaxial tensile tests at quasi-static and dynamic strain rates at room temperature. The influence of the strain rate is outlined and experimental results were fitted to the parameters of Johnson-Cook constitutive material model. In the second stage of the present study, sheets of AZ31B magnesium alloy have been biaxially formed by electromagnetic forming using different coil and die configurations. Deformation values measured from electromagnetic formed parts are compared to the ones achieved with uniaxial tensile tests and also with the values obtained by conventional forming technologies. Finally, numerical simulations have been carried out using an alternative method for computing the electromagnetic fields in the EMF process simulation, a combination of Finite Element Method (FEM) for conductor parts and Boundary Element Method (BEM) for the surrounding air (or more generally insulators) that is being implemented into commercial code LS-DYNA®.

description: We report on a new class of mechanically tunable planar metamaterials comprising resonating units formed by crossed metallic strip gratings. We observe a resonant response in transmission spectra of a linearly polarized wave passing through the system of crossed gratings. Each grating consists of an array of parallel metallic strips located on the top of a dielectric substrate. It is revealed that the resonant position appears to be dependent on the angle of gratings crossing. It is found out both theoretically and experimentally that the resonant shift on the frequency scale appears as a result of increasing in the length of the resonating portion of the parallelogram periodic cell formed by the crossed metallic strips with decreasing crossing angle and the proposed design can be used in new types of planar metamaterials and filters.

description: Episodic memory is the type of memory that allows the recollection of personal experiences containing information on what has happened and, also, where and when it happened. Because of its sensitivity to brain’s aging and the neurodegenerative diseases it is considered a hallmark of Alzheimer’s Disease Dementia (ADD). The objective of the present study was to examine episodic memory in amnestic mild cognitive impairment (aMCI) and ADD. Patients with the diagnosis of early aMCI, late aMCI and mild ADD were evaluated using the Doors and People tool which consists of four subtests examining different aspects of episodic memory. The statistical analysis with ROC curves showed the discriminant potential and the cutoffs of every subtest. Overall, the evaluation of episodic memory with Doors and People tool can discriminate with great sensitivity between the different groups of people with ADD, and, especially, early aMCI, late aMCI and mild ADD patients.

description: Asteroseismology probes the interiors of stars by studying oscillation modes at a star's surface. Although pulsation spectra are well understood for solar-like oscillators, a substantial fraction of red giant stars observed by Kepler exhibit abnormally low-amplitude dipole oscillation modes. Fuller et al. (2015) suggests this effect is produced by strong core magnetic fields that scatter dipole internal gravity waves (IGWs) into higher multipole IGWs or magnetic waves. In this paper, we study the interaction of IGWs with a magnetic field to test this mechanism. We consider two background stellar structures: one with a uniform magnetic field, and another with a magnetic field that varies both horizontally and vertically. We derive analytic solutions to the wave propagation problem and validate them with numerical simulations. In both cases, we find perfect conversion from IGWs into magnetic waves when the IGWs propagate into a region exceeding a critical magnetic field strength. Downward propagating IGWs cannot reflect into upward propagating IGWs because their vertical wavenumber never approaches zero. Instead, they are converted into upward propagating slow (Alfvenic) waves, and we show they will likely dissipate as they propagate back into weakly magnetized regions. Therefore, strong internal magnetic fields can produce dipole mode suppression in red giants, and gravity modes will likely be totally absent from the pulsation spectra of sufficiently magnetized stars.

Viability of exact tri-bimaximal, golden-ratio and bimaximal mixing patterns and renormalization-group running effects

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In light of the latest neutrino oscillation data, we examine whether the leptonic flavor mixing matrix can take on an exact form of tri-bimaximal (TBM), golden-ratio (GR) or bimaximal (BM) mixing pattern at a superhigh-energy scale, where such a mixing pattern could be realized by a flavor symmetry, and become compatible with experimental data at the low-energy scale. Within the framework of the Minimal Supersymmetric Standard Model (MSSM), the only hope for realizing such a possibility is to count on the corrections from the renomalization-group (RG) running. In this work we focus on these radiative corrections, and fully explore the allowed parameter space for each of these mixing patterns. We find that when the upper bound on the sum of neutrino masses $Σ^{}_ν\equiv m^{}_1 + m^{}_2 + m^{}_3 < 0.23~\text{eV}$ at the $95\%$ confidence level from Planck 2015 is taken into account, none of these mixing patterns can be identified as the leptonic mixing matrix below the seesaw threshold. If this cosmological upper bound on the sum of neutrino masses were relaxed, the TBM and GR mixing patterns would still be compatible with the latest neutrino oscillation data at the $3σ$ level, but not at the $1σ$ level. Even in this case, no such a possibility exists for the BM mixing.

The Galactic Club, or Galactic Cliques? Exploring the limits of interstellar hegemony and the Zoo Hypothesis

Year: 2016
Subjects: subject: Popular Physics (physics.pop-ph)

description: The Zoo solution to Fermi's Paradox proposes that extraterrestrial intelligences (ETIs) have agreed to not contact the Earth. The strength of this solution depends on the ability for ETIs to come to agreement, and establish/police treaties as part of a so-called "Galactic Club". These activities are principally limited by the causal connectivity of a civilisation to its neighbours at its inception, i.e. whether it comes to prominence being aware of other ETIs and any treaties or agreements in place. If even one civilisation is not causally connected to the other members of a treaty, then they are free to operate beyond it and contact the Earth if wished, which makes the Zoo solution "soft". We should therefore consider how likely this scenario is, as this will give us a sense of the Zoo solution's softness, or general validity. We implement a simple toy model of ETIs arising in a Galactic Habitable Zone, and calculate the properties of the groups of culturally connected civilisations established therein. We show that for most choices of civilisation parameters, the number of culturally connected groups is greater than 1, meaning that the Galaxy is composed of multiple Galactic Cliques rather than a single Galactic Club. We find in our models for a single Galactic Club to establish interstellar hegemony, the number of civilisations must be relatively large, the mean civilisation lifetime must be several millions of years, and the inter-arrival time between civilisations must be a few million years or less.

description: This work begins with an introductory framework which explains and analyzes the term of geography, as part of the world around us. In particular, there will be an effort of locating the crucial features which mark geography as so important in the process of strategic planning. Consequently, there will be examined the exact terminology related to the field of geopolitics, thus setting the basis for the understanding and interpretation of events governing the international relations. Moreover, matters of power relations will be analyzed, while special reference will consider the categorization of powers, in order to thoroughly examine the moves of great powers, always bearing in mind the emergence of new challenges. Individual chapters will be dedicated to the part of the economy and the timeless causes of war. Finally, the work ends with a chapter venturing to present specific conclusions concerning the prevailing situation in modern era.

description: We calculate superconducting gaps and quasiparticle density of states of YNi$_2$B$_2$C in the framework of the density functional theory for superconductors to investigate the origin of a highly anisotropic superconducting gaps in this material. Calculated phonon frequencies, the quasiparticle density of states, and the transition temperature show good agreement with experimental results. From our calculation of superconducting gaps and orbital character analysis, we establish that the orbital character variation of the Fermi surface is the key factor of the anisotropic gap. Since the electronic states that consist of mainly Ni $3 d$ orbitals couple weakly with phonons, the superconducting gap function is suppressed for the corresponding states, which results in the anisotropy observed in the experiments. These results are hints to increase the transition temperature of materials in the borocarbide family.

description: Η μορφή του Συνοδικού Θεσμού ως σύστημα διοικήσεως της Ορθοδόξου Εκκλησίας αποτελεί το πλέον δημοκρατικό μέσο διοικήσεως. Στην μεταπτυχιακή εργασία που θα εκπονήσουμε, θα καταβληθεί προσπάθεια να εξεταστεί ο Συνοδικός Θεσμός και ο ρόλος του Πρώτου στον χώρο της Εκκλησίας της Ελλάδος. Σκοπός της εργασίας είναι το πώς διαρθρώθηκε το Συνοδικό σύστημα ως μορφή διοικήσεως της Ελλαδικής Εκκλησίας αλλά και ποιός είναι ο ρόλος του Πρώτου σε αυτήν. Η εργασία θα αποτελείται από τρία κεφάλαια. Στην αρχή, θα παρουσιάσουμε το θεολογικό και ιστορικό περίγραμμα αυτού του σπουδαίου και θεμελιώδους θεσμού διοικήσεως της Ορθόδοξου Εκκλησιάς, του Συνοδικού Θεσμού. Στη συνέχεια, η έρευνα μας θα επικεντρωθεί στην μελέτη των πηγών και ιδιαίτερα των πρακτικών της συνόδου και των Καταστατικών Χαρτών, στο πως αποτυπώθηκε ο συγκεκριμένος θεσμός, ο Συνοδικός Θεσμός, αλλά και η θέση του Πρώτου στην Εκκλησία της Ελλάδος. Με δεδομένο ότι η Αυτοκεφαλία της πρόεκυψε με έναν τρόπο επαναστατικό στην αφετηρία της και στη συνέχεια με την παρέμβαση του Οικουμενικού Πατριαρχείου με τη χορήγηση των Συνοδικών Τόμων, αλλά και με το υφιστάμενο ιδιότυπο καθεστώς των Νέων Χωρών, το ζήτημα αυτό αποκτάει ιδιαίτερη σπουδαιότητα και θα εξετασθεί στα τρία κεφάλαια τα οποία με το σύμβουλο καθηγητή έχουμε συνεννοηθεί να το αποτυπώσουμε
description: The form of the Synodical Institution as a system of administration of the Orthodox Church is the most democratic means of administration. In the Master’s Thesis that we will prepare, an effort will be made to examine the Synodical Institution and the role of the Primus in the Church of Greece. The purpose of the paper is how the Synodical system was structured as a form of administration of the Greek Church and what is the role of the Primus in it. The work will consist of three chapters. In the beginning, we will present the theological and historical outline of this great and fundamental governing institution of the Orthodox Church, the Synodical Institution. Then, our research will focus on the study of the sources and especially of the acts of the Synod and the Church’s Constitution, on how the specific institution, the Synodical Institution, but also the position of the Primus in the Church of Greece was reflected. Given that its Autocephaly emerged in a revolutionary way at its starting point and then with the intervention of the Ecumenical Patriarchate with the granting of the Synodical Tomos, but also with the existing peculiar regime of the New Lands (Νέες Χώρες), this issue acquires particular importance and will be examined in the three chapters which the professor advisor and I have agreed to capture

description: Purpose: To introduce and evaluate the use of stable distributions as a means of describing the behavior of charged particle pencil beams in a medium, with specific emphasis on proton beam scanning (PBS). Methods: The proton pencil beams of a clinically commissioned proton treatment facility are replicated in a Monte Carlo simulation system (FLUKA). For each available energy the beam deposition in water medium is characterized by the dose deposition. Using an alpha--stable distribution methodology each beam with a nominal energy $E$ is characterized by the lateral spread at depth $z$: $S(z;α,γ,E)$ and a total energy deposition $I_D(z)$. The beams are then described as a function of the variation of the parameters at depth. Finally, an implementation in a freely available open source dose calculation suite (matRad, DKFZ, Heidelberg, Germany) is proposed. Results: Quantitatively, the fit of the stable distributions, compared to those implemented in standard treatment planning systems, are equivalent. The efficiency of the representation is better (2 compared to 3 and more parameters needed). The meta--parametrization (i.e. the description of the dose deposition by only providing the fitted parameters) allows for interpolation of non--measured data. In the case of the clinical data used in this paper, it was possible to only commission 1 out of 5 nominal energies to obtain a viable data set. Conclusions: Alpha--stable distributions are intrinsically suited to describe charged particle pencil beams in a medium and can be easily implemented in existing treatment planning systems. The use of alpha-distributions can easily be extended to other particles.

description: Ο ιστορικός ναός του Αγίου Νικολάου των Λαγυνών, της μικρής κωμόπολης του νομού Θεσσαλονίκης, είναι ένας από τους αναρίθμητους ναούς στον Ελλαδικό χώρο που είναι αφιερωμένοι στον Άγιο Νικόλαο, έναν από τους πιο δημοφιλείς αγίους του χριστιανικού κόσμου. Ο Άγιος Νικόλαος θεωρείται ο κατεξοχήν προστάτης των ναυτικών και στον βίο του αναφέρονται πολλά θαύματα που έχουν σχέση με την θάλασσα. Η ζωή του υπήρξε παράδειγμα ευσπλαχνίας, αγάπης και φιλανθρωπίας γεγονός που τον κατέστησε ιδιαίτερα αγαπητό στους ανθρώπους και φάρο πίστης και ελπίδας στην πολυκύμαντη ζωή τους. Έτσι εξηγείται και η ύπαρξη ναών στην χάρη του ακόμη και σε ορεινές περιοχές της ηπειρωτικής Ελλάδας και όχι μόνο σε παραθαλάσσιες τοποθεσίες ή νησιά, όπως ακριβώς και στην περιοχή των Λαγυνών. Ο ιστορικός ναός του Αγίου Νικολάου αποτελεί αντιπροσωπευτικό δείγμα της αρχιτεκτονικής και της ζωγραφικής τέχνης που επικρατούσε κατά τον 19ο αιώνα στην ευρύτερη περιοχή της Κεντρική Μακεδονίας. Εξαιρετικό ενδιαφέρον παρουσιάζει το τέμπλο του με εικόνες και παραστάσεις φιλοτεχνημένες από δημιουργούς που προέρχονται κυρίως από την περιοχή του Κιλκίς και από τα αγιογραφικά εργαστήρια της Κολακιάς- σημερινής Χαλάστρας- χαρακτηριστικό των οποίων ήταν ο έντονα λαϊκότροπος διάκοσμος. Ο ναός του Αγίου Νικολάου ακόμη και λόγω της περίοπτης θέσης του αποτελεί στολίδι για την περιοχή των Λαγυνών αλλά και ξεχωριστό μνημείο του 19ου αιώνα στην Κεντρική Μακεδονία
description: The historic church of Saint Nickolas in Lagyna, which is a small town of the prefecture of Thessaloniki, is one of the countless churches in Greece dedicated to Saint Nickolas, one of the most popular saints in the Christian world. Saint Nickolas is considered as the main patron saint of sailors and many miracles which are related to the sea, accredit to him. His whole life was an example of compassion, love and charity, a fact that made him well loved to troubled people and a lighthouse of faith and hope for them. This explains the existence of churches in his favor even in the mountainous areas of mainland Greece and not only in coastal locations or islands, just like this one. The historic church of Saint Nickolas is a representative sample of the architecture and painting art that prevailed during the 19th century in the wider region of Central Macedonia. Its Iconostasis is extremely interesting with icons and pictures created by them who came mainly from the Kilkis region and from the hagiographic workshops of Kolakia – the present town of Halastra nearby Thessaloniki- whose characteristic was the intensely populist decoration. That church due to its prominent position, is a piece of jewellery for the region of Lagyna but also a special monument of 19th century in Central Macedonia
Measurement of the top quark mass in the $t\bar{t}\to$ dilepton channel from $\sqrt{s}=8$ TeV ATLAS data

description: The top quark mass is measured in the $t\bar{t}\to$ dilepton channel (lepton $= e, μ$) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton--proton centre-of-mass energy of $\sqrt{s}=$ 8 TeV and correspond to an integrated luminosity of about 20.2 fb$^{-1}$. Exploiting the template method, and using the distribution of invariant masses of lepton--b-jet pairs, the top quark mass is measured to be $m_{top} =$ 172.99 $\pm$ 0.41 (stat) $\pm$ 0.74 (syst) GeV, with a total uncertainty of 0.84 GeV. Finally, a combination with previous ATLAS $m_{top}$ measurements from $\sqrt{s}=$7 TeV data in the $t\bar{t}\to$ dilepton and $t\bar{t}\to$ lepton+jets channels results in $m_{top} =$ 172.84 $\pm$ 0.34 (stat) $\pm$ 0.61 (syst) GeV, with a total uncertainty of 0.70 GeV.

description: Η χειρουργική επέμβαση πλοήγησης φρουρού, επικυρωμένη κατάλληλα, μπορεί πιθανώς να διαδραματίσει σημαντικό, αλλά καλά καθορισμένο, ρόλο στην οριστική θεραπεία του καρκίνου του στομάχου δημιουργώντας, όταν χρειάζεται, τις συνθήκες για στοχευμένες αλλά ογκολογικά αποτελεσματικές λεμφαδενεκτομές. Ωστόσο, υπάρχουν αρκετά προβλήματα στην ίδια την τεχνική και στις ενδείξεις που απαιτούν πειστικές απαντήσεις, όπως ευκολία στη χρήση και οπτικοποίηση των ανιχνευτών σε πραγματικό χειρουργικό χρόνο, σύντομη και ακριβή παθολογία και τελικά κατάλληλη επιλογή ασθενούς. Όσον αφορά τους ιχνηθέτες, ο συνδυασμός ανιχνευτών (χρωστική ουσία συν ισότοπο) φαίνεται να είναι η πιο αποτελεσματική και κοινώς ακολουθούμενη προσέγγιση λόγω των αυξημένων ρυθμών ανίχνευσης. Η χρώση με αιματοξυλίνη/ηωσίνη εξακολουθεί να είναι η πιο χρησιμοποιούμενη μέθοδος όσον αφορά τη χρώση των κομμένων κόμβων λόγω των συνολικών πλεονεκτημάτων της σε σύγκριση με τις άλλες πιο ακριβείς αλλά δύσκολες στη χρήση σε καθημερινές μεθόδους πρακτικής. Η προσέγγιση του διαχωρισμού της λεμφικής παροχεύτεσης φαίνεται πολλά υποσχόμενη, διότι υπό ορισμένες συνθήκες θα μπορούσε να αντιμετωπίσει και να αντισταθμίσει τους υπάρχοντες περιορισμούς της διαδικασίας στην τρέχουσα μορφή της. Τα διδάγματα που αντλήθηκαν από τη λήξη της μελέτης λόγω των αποτελεσμάτων, εάν εκτιμηθούν κατάλληλα, μπορούν να μετατραπούν από ανυπέρβλητα εμπόδια στο σκαλοπάτι για την πραγματική πρόοδο στο πεδίο με άμεση κλινική αντιστοιχία.
description: Sentinel node navigation surgery, validated appropriately, can probably play a significant, but well-defined, role in the definite treatment of gastric cancer creating, when appropriate, the conditions for targeted but oncologically effective lymphadenectomies. However, there are several problems on the technique itself and on the indications as well that require convincing answers such as easy to use and to visualize tracers in real operative time, brief and precise pathology and ultimately appropriate patient selection. In regards to tracers, combining tracers (dye plus isotope) seems to be the most effective and commonly followed approach due to the increased detection rates. Hematoxylin/eosin staining is still the mostly utilized method in regards to staining of the picked up nodes due to its overall advantages compared to the other more precise but the hard to use in everyday practice methods. The approach of lymphatic basin dissection seems promising because under certain circumstances could address and counterbalance existing limitations of the procedure in its current form. The lessons learned from the terminated study due to the unacceptable results, if appreciated appropriately, can turn from insurmountable obstacles to the stepping stone for actual progress on the field with direct clinical correspondence.

description: La fouille de Mas de Vignoles IX s’est déroulée en 2004 et portait essentiellement sur la fouille d’une occupation rurale protohistorique accolée à un tronçon de voie probablement contemporain. Dans les emprises à décaper, un peu plus de 3 hectares, le diagnostic avait également permis la détection de vestiges du Néolithique, moyen et final, et de l’Antiquité romaine. À cette époque, c’était la première fois qu’un décapage d’une certaine ampleur portait sur l’étude d’un établissement rural gaulois à distance de l’oppidum. Les questions qui se posaient étaient de savoir si ce type d’établissement avait été habité de façon pérenne, comment il était structuré et surtout quelles activités agricoles ou autres étaient pratiquées.
