description: Την τελευταία δεκαετία, ένας αυξανόμενος αριθμός ερευνητικών ομάδων παγκοσμίως αναφέρουν τη δημιουργία και τη χρήση της κυτταρίνης, ινίδια ή κρύσταλλοι σε κλίμακα νανομέτρων. Καθώς η επιστήμη και η τεχνολογία συνεχίζουν να προσανατολίζονται προς τη χρήση ανανεώσιμων πρώτων υλών και περισσότερο περιβαλλοντικά φιλικών και βιώσιμων πόρων και διεργασιών, η ανάπτυξη της νανοκυτταρίνης αποτελεί μία σημαντική συνιστώσα αυτής της τάσης με ζωτική σημασία. Στα πλαίσια της παρούσας διπλωματικής εργασίας παρασκευάστηκαν νανοκρύσταλλοι κυτταρίνης (CNCs) με υδρόλυση με θειϊκό και υδροχλωρικό οξύ μικροκρυσταλλικής κυτταρίνης (MCC) και πραγματοποιήθηκε δοκιμή για σταθεροποίηση γαλακτώματος ελαίου σε νερό με τους νανοκρυστάλλους. Το εναιώρημα των νανοκρυστάλλων κυτταρίνης παρατηρήθηκε με μικροσκοπία πολωμένου φωτός. Επιπρόσθετα, περιγράφεται η παρασκευή εδώδιμων μεμβρανών πουλλουλάνης και πρωτεϊνών ορού γάλακτος (WPI) ενισχυμένες με CNCs, με σκοπό τη μελέτη των μηχανικών και νανομηχανικών ιδιοτήτων των νανοσύνθετων μεμβρανών. Ο χαρακτηρισμός των μεμβρανών πραγματοποιήθηκε με μικροσκοπία ατομικών δυνάμεων (AFM), περίθλαση ακτίνων-Χ (XRD), μηχανικές δοκιμές μεγάλων παραμορφώσεων και νανομηχανικές μετρήσεις (νανοεγχάραξη). Συμπερασματικά, τα αποτελέσματα αυτής της μελέτης υποδεικνύουν ότι οι CNCs μπορούν να σχηματίσουν σταθερά κολλοειδή συστήματα διασποράς και να ενισχύσουν τις μηχανικές και νανομηχανικές ιδιότητες των μεμβρανών πουλλουλάνης και WPI.
description: During the last decade, an increasing number of research groups worldwide reported the creation and use of cellulose fibrils or crystals at the nanometer scale. As science and technology continue to be oriented towards the use of renewable raw materials and more environmentally friendly and sustainable resources and processes, the development of nanocellulosics is an important component of this vital movement. We have fabricated cellulose nanocrystals (CNCs) following hydrolysis with sulfuric and hydrochloric acid of microcrystalline cellulose (MCC) and we tested them for stabilizing oil-in-water emulsions. The dispersion of cellulose nanocrystals was observed with polarized light microscopy. Furthermore, the preparation of edible pullulan and WPI films reinforced with cellulose nanocrystals is described, in order to explore the mechanical and nanomechanical properties of the composite films. The characterization of membranes was conducted with atomic force microscopy (AFM), X-ray diffraction (XRD), large deformation mechanical tests and nanomechanical measurements (nanoindentation). Overall, the results of this study indicate that CNCs can form stable colloidal suspensions and enhance the mechanical and nanomechanical characteristics of WPI and pullulan films.
Haplotype-based inference of recombination in Escherichia coli ST131 genomes highlights subtype displacement in long-term care facilities

description: The evolution and transmission of antimicrobial resistant bacteria is a major threat to public health. Escherichia coli sequence type ST131 (O25:H4) is a pandemic multidrug-resistant pathogen and is associated with the CTX-M-15 extended-spectrum beta-lactamase. PFGE- and MLST-based approaches have much less power compared to genome-sequencing to resolve pathogen evolution due to the lower number of biomarkers. Moreover, standard methods for partitioning variation into discrete categories can miss recombination events. In this study spanning 2005-2011, 96 E. coli isolates were collected from hospitals (n=8), the community (n=2) and from residents in eleven long-term care facilities across Ireland (n=11) and one single care facility (n=69 from 63 residents). 90 of the 96 (94%) were ST131: these were compared with 11 other Indian/UK ST131 for evolutionary context (n=101). After Illumina Hiseq sequencing, reading-mapping and conservative variant calling, a total 8,687 SNPs were discovered in these 101 genomes. Phylogenomic and model-based analyses indicated five discrete populations, but only when non-recombining SNPs were excluded. Subsequent evaluations of haplotype flow within and between populations over time indicated periodical displacement of distinct populations within little recombination overall between groups, including one displacement event within a single resident. Haplotype-based inference of recombination indicated that a binary differentiation of mutations in ones arising by recombination or not across the whole collection limited inferences because most recombination events were between isolate pairs. This scheme identified the transferred genes as transposases, bacteriophage elements and pathogenicity islands. This highlighted the importance of sensitive approaches for untangling historical patterns of horizontal gene exchange.

description: In general, the system of $2$nd-order partial differential equations made of the Euler-Lagrange equations of classical field theories are not compatible for singular Lagrangians. This is the so-called second-order problem. The first aim of this work is to develop a fully geometric constraint algorithm which allows us to find a submanifold where the Euler-Lagrange equations have solution, and split the constraints into two kinds depending on their origin. We do so using $k$-symplectic geometry, which is the simplest intrinsic description of classical field theories. As a second aim, the Einstein-Palatini model of General Relativity is studied using this algorithm.

description: One contribution to the time resolution of a scintillation detector is the signal time spread due to path length variations of the detected photons from a point source. In an experimental study a rectangular scintillator was excited by means of a fast pulsed ultraviolet laser at different positions along its longitudinal axis. Timing measurements with a photomultiplier tube in a detection plane displaced from the scintillator end face showed a correlation between signal time and tube position indicating only a small distortion of photon angles during transmission. The data is in good agreement with a Monte Carlo simulation used to compute the average photon angle with respect to the detection plane and the average propagation time. Limitations on timing performance that arise from propagation time dispersion are expected for long and thin scintillators used in future particle identification systems.

description: Mass Spectrometers provide insight into molecular composition and structures of proteins. However proteins with similar mass to charge ratio and, above all, isomers, cannot be easily distinguished. To bypass these issues, chemical reactions are used to fragment sample ions, revealing more of their nature. One of the relatively new techniques to do it is by using Electron Transfer Dissociation. Compared to other methods, this technique induces fragmentation of highly specific bonds. Understanding its dynamics is important for the optimisation of experimental settings.

Here we present a workflow for analysis of data from mass spectrometer coming from a fixed known substance. The aim of this workflow is to understand the dynamics of the system of ions undergoing a fragmentation process. We assume that the observed data is generated by a hidden continuous time Markov chain with a discrete state space. The model is highly endogenous – the number of external parameters is small. In this way we obtain a model with statistically identifiable parameters and easy interpretation. We fit the model in the bayesian setting using cutting-edge statistical techniques, based on the idea of particle Gibbs for Markov Jump processes and Fast MCMC sampling for Markov jump processes. Our initial results obtained on in-silico data is very promising.

We present an effective theory which allows us to account for X-ray light curves of both (short - long) gamma ray bursts and X-ray rich flashes. We propose that gamma ray bursts originate from massive magnetic powered pulsars.

Exact solution of non-Hermitian systems with generalized boundary conditions: size-dependent boundary effect and fragility of skin effect

description: Systems with non-Hermitian skin effects are very sensitive to the imposed boundary conditions and lattice size, and thus an important question is whether non-Hermitian skin effects can survive when deviating from the open boundary condition. To unveil the origin of boundary sensitivity, we present exact solutions for one-dimensional non-Hermitian models with generalized boundary conditions and study rigorously the interplay effect of lattice size and boundary terms. Besides the open boundary condition, we identify the existence of non-Hermitian skin effect when one of the boundary hopping terms vanishes. Apart from this critical line on the boundary parameter space, we find that the skin effect is fragile under any tiny boundary perturbation in the thermodynamic limit, although it can survive in a finite size system. Moreover, we demonstrate that the non-Hermitian Su-Schreieffer-Heeger model exhibits a new phase diagram in the boundary critical line, which is different from either open or periodical boundary case.

description: The density field reconstruction technique has been widely used for recovering the Baryon Acoustic Oscillation (BAO) feature in galaxy surveys that has been degraded due to nonlinearities. Recent studies advocated adopting iterative steps to improve the recovery much beyond that of the standard technique. In this paper, we investigate the performance of a few selected iterative reconstruction techniques focusing on the BAO and the broadband-shape of the two-point clustering. We include redshift-space distortions, halo bias, and shot noise and inspect the components of the reconstructed field in Fourier space and in configuration space using both density field-based reconstruction and displacement field-based reconstruction. We find that the displacement field reconstruction becomes quickly challenging in the presence of non-negligible shot noise and therefore present surrogate methods that can be practically applied to a much more sparse field such as galaxies. For a galaxy field, implementing a debiasing step to remove the Lagrangian bias appears crucial for the displacement field reconstruction. We show that the iterative reconstruction does not substantially improve the BAO feature beyond an aggressively optimized standard reconstruction with a small smoothing kernel. However, we find taking iterative steps allows us to use a small smoothing kernel more `stably', i.e., without causing a substantial deviation from the linear power spectrum on large scales. In one specific example we studied, we find that a deviation of 13\% in $P( k \sim 0.1h/Mpc)$ with an aggressive standard reconstruction can reduce to 3-4\% with iterative steps.

description: This volume covers Leg 66 of the cruises of the Drilling Vessel Glomar Challenger. Plate tectonics has raised a number of new and intriguing questions, especially concerning subduction complexes, subduction mechanics, and evolution of subduction zones. Answering these questions has been difficult, owing in part to the problem of studying active subduction complexes. Seismic reflection investigations have been frustrated by the complex structures of subduction complexes, and Deep Sea Drilling Project efforts to sample subduction complexes have been similarly frustrated by thick hemipelagic slope apron deposits that limit penetration into the deformed rocks and sediments. Leg 66 was part of a broader effort to overcome these difficulties and contribute to the resolution of critical questions about subduction. Leg 66 is actually part of two broader investigations of subduction complexes and convergent margin geology—one led by the Active Margin Panel (AMP) of the International Phase of Ocean Drilling (IPOD) to drill selected convergent margins to elucidate structure and evolution and the other, led by the University of Texas Marine Science Institute Galveston Geophysical Laboratory to investigate the tectonics of the Middle America Trench from the Cocos Fracture Zone to the Riviera Fracture Zone. The synergism of these two efforts resulted in the drilling of Legs 66 and 67 off southwestern Mexico and Guatemala, respectively. The present volume and Volume 67 are thus companion efforts. Leg 66 began in Mazatlán, Mexico in March of 1979 and ended in Manzanillo, Mexico in May of 1979.

description: We investigate the massive Schwinger model in $d=1+1$ dimensions using bosonization and the nonperturbative functional renormalization group. In agreement with previous studies we find that the phase transition, driven by a change of the ratio $m/e$ between the mass and the charge of the fermions, belongs to the two-dimensional Ising universality class. The temperature and vacuum angle dependence of various physical quantities (chiral density, electric field, entropy density) are also determined and agree with results obtained from density matrix renormalization group studies. Screening of fractional charges and deconfinement occur only at infinite temperature. Our results exemplify the possibility to obtain virtually all physical properties of an interacting system from the functional renormalization group.

Παράλληλα με την ιστορική έρευνα του Ινστιτούτου Καπνού ξεκίνησαν και οι απαραίτητες εργασίες για την πλήρη γεωμετρική αποτύπωση του κεντρικού κτιρίου εργαστηρίων και της σχέσης του με τις υπόλοιπες κτιριακές εγκαταστάσεις. Οι παραπάνω εργασίες οδήγησαν στην πλήρη γνώση της τυπολογίας και μορφολογίας του κτιρίου, της κατασκευαστικής του δομής και της παθολογίας του. Αξιολογώντας όλα τα στοιχεία που προέκυψαν από την ανάλυση, έγινε μια πρώτη διερεύνηση για την επανάχρηση του συγκροτήματος καθώς και για την αποκατάσταση του κεντρικού Κτιρίου Εργαστηρίων, σεβόμενη πάντα όλα τα ιδιαίτερα χαρακτηριστικά που αναδεικνύουν τη μοναδικότητά του.
description: This work is summarized in three distinct sections.concerning the historical analysis, the justification of the existing situation and the reuse and restoration proposals. Specifically, in the first stage, an attempt was made to present the history of the Institute so as to understand the historical and social context of the era it was built. Data obtained from this analysis led to the understanding of its value something that greatly influenced the reuse proposal. In parallel with the historical research of the Tobacco Institute, survey work necessary for the complete geometric mapping of the Labs Building began as well as its relation to other buildings. This work resulted in the full knowledge of the typology and morphology of the building, its structure and pathology. Evaluating all elements from the analysis, a first investigation of the reuse as well as the restoration of the main Labs Building was made, while respecting all the features that highlight its uniqueness.
Re-entrant ferromagnetism in a generic class of diluted magnetic semiconductors

description: Considering a general situation where a semiconductor is doped by magnetic impurities leading to a carrier-induced ferromagnetic exchange coupling between the impurity moments, we show theoretically the possible generic existence of three ferromagnetic transition temperatures, T_1 > T_2 > T_3, with two distinct ferromagnetic regimes existing for T_1 > T > T_2 and T < T_3. Such an intriguing re-entrant ferromagnetism, with a paramagnetic phase (T_2 > T > T_3) between two ferromagnetic phases, arises from a subtle competition between indirect exchange induced by thermally activated carriers in an otherwise empty conduction band versus the exchange coupling existing in the impurity band due to the bound carriers themselves. We comment on the possibility of observing such a re-entrance phenomenon in diluted magnetic semiconductors and magnetic oxides.

description: В работе, на примере решения двумерного нестационарного волнового уравнения, приведено описание применения процедуры прямой минимизации функционала при помощи приведения к системе обыкновенных дифференциальных уравнений. Данная процедура называется методом Канторовича. Рассмотренное волновое уравнение применяется в различных предметных областях, например, в теории упругости. Поэтому нахождение его решения представляет практический интерес. В работе проведен анализ динамики упругой мембраны при внешней гармонической сосредоточенной нагрузке. Точное определение величины прогиба прямоугольной мембраны-элемента в месте воздействия гармонической сосредоточенной нагрузки при нестационарных колебаниях, является крайне важной задачей при проектировании упругих чувствительных элементов современных микромеханических преобразователей. В предлагаемом исходном коде на языке Maple содержится множество комментариев, которые помогут понять, как можно модифицируется заданная математическая модель объекта. Кроме того, решение можно вывести в графическом виде, что позволяет достаточно легко проводить анализ на предмет его зависимости от координатных функций и их количества.

description: Cough variant asthma (CVA) is well-known as a subtype of asthma that is characterized by a chronic cough. Roxithromycin (ROX) and theophylline (TH) have a synergistic effect on CVA. In this study, concomitant drugs-loaded microcapsules (CDM) of ROX and TH were prepared by spray drying with amphiphilic methylcellulose (MC) and sodium Alginate (Alg) as the wall materials. The preparation conditions and wall materials components had been optimized and MC/Alg/MC had the highest encapsulation efficiency. With MC/Alg/MC as the wall material, microcapsules of concomitant drugs had higher drug loading than those of the single drug. CDM expressed obvious pH-sensitive controlled-release behavior. After 12 h releasing, the cumulative release of ROX and TH at pH 1.5 was 21.07% and 22.31%, 73.14% and 97.52% at pH 7.4, respectively. The antibacterial efficacy of pure drugs and CDM further proved that controlled-release was achieved in CDM. Cytotoxicity test on neutrophils also confirmed that CDM were less toxic to cells than the pure drugs.

description: Landau Fermi liquid theory predicts that the differential conductivity between metallic point and metal is a symmetric function of voltage bias V. This symmetry holds if the particle-hole symmetry is preserved. We show that the situation can be different when one of the two metals is a strongly correlated one whose electronic system can be represented by a heavy fermion liquid. When the heavy fermion liquid undergoes fermion condensation quantum phase transition, the particle-hole symmetry is violated making both the differential tunneling conductivity and dynamic conductance asymmetric as a function of applied voltage. This asymmetry can be observed when the strongly correlated metal is either normal or superconducting. We show that at small values of $V the asymmetric part of the dynamic conductance is a linear function of V and inversely proportional to the maximum value of the gap and does not depend on temperature provided that metal is superconducting, when it becomes normal the asymmetric part diminishes at elevated temperatures.

description: We demonstrate the existence of special phantom excitations for open and periodically closed integrable systems at the example of the $XXZ$ Heisenberg spin chain. The phantom excitations do not contribute to the energy of the Bethe state and correspond to special solutions to the Bethe Ansatz equations with infinite "phantom" Bethe roots. The phantom Bethe roots lead to degeneracies between different magnetization sectors in the periodic case and to the appearance of spin helix states (SHS), i.e. periodically modulated states of chiral nature in both open and closed systems. For the periodic chain, phantom Bethe root (PBR) solutions appear for anisotropies $\De=\coshη$ with $\exp(η)$ being a root of unity, thus restricting the phenomenon to the critical region $|\De|<1$. For the open chain, PBR solutions appear for any value of anisotropy, both in the critical and in the non-critical region, provided that the boundary fields satisfy a criterion which we derive in this paper. There exist PBR solutions with all Bethe roots being phantom, and PBR solutions that consist of phantom roots as well as regular (finite) roots. Implications of our results for an experiment are discussed.

description: We propose an experimentally feasible architecture with controllable long-range couplings built up from local exchange interactions. The scheme consists of a spin-bus, with strong, always-on interactions, coupled dynamically to external qubits of the Loss and DiVincenzo type. Long-range correlations are enabled by a spectral gap occurring in a finite-size chain. The bus can also form a hub for multiqubit entangling operations. We show how multiqubit gates may be used to efficiently generate $W$-states (an important entanglement resource). The spin-bus therefore provides a route for scalable solid-state quantum computation, using currently available experimental resources.

HoTMuSiC : Predicting protein thermal stability change upon point mutations

description: The prediction of the protein thermal stability changes upon point mutations is an important and highly non-trivial goal in protein science with a wide series of biotechnological applications. We tackle this problem by building a tool called HoTMuSiC that uses as input the three-dimensional protein structure and is able to predict ΔTm, the change upon mutations of the best descriptor of the thermal stability, i.e. the melting temperature Tm. It performs considerably better respect to the other tools presented in the literature and moreover it is fast enough to allow a complete scan of all the protein’s residues in order to identify the mutations that mostly increase the protein thermoresistance.

description: В статье анализируется процесс формирования банковского союза и союза рынка капиталов Европейского союза. Рассмотрены институциональные, процессуальные, экономические основы этого процесса и раскрыты сопровождающие его проблемы и противоречия. Среди главных из них авторы выделяют следующие: банковская система еврозоны страдает от структурно обусловленной низкой рентабельности и значительных объемов проблемных кредитов; чрезмерная зависимость европейских банков от правительств; противоречия между формальными институтами Европейского союза и неформальными институциональными нормами, укоренившимися в национальных культурах и другие. Проведенный анализ позволил сформулировать общие рекомендации и авторскую оценку перспектив данных процессов. В частности сформулирован вывод о необходимости создания эффективных механизмов рыночного регулирования и их приоритете над процессами либерализации рынков. Не менее важным является безусловный учет специфики локальных финансовых рынков как основы для формирования банковского союза и союза рынка капиталов Европейского союза.The article analyzes the process of forming a banking union and a union of the capital market of the European Union. The institutional, procedural, and economic bases of this process are examined and the accompanying problems and contradictions are revealed. Among the main ones, the authors point out the following: the eurozone banking system suffers from a structurally determined low profitability and significant volumes of problem loans; excessive dependence of European banks on governments; contradictions between the formal institutions of the European Union and informal institutional norms that are rooted in national cultures and others. The analysis made it possible to formulate general recommendations and the author's assessment of the prospects of these processes. In particular, a conclusion was formulated on the need to create effective mechanisms of market regulation and their priority over the processes of market liberalization. No less important is the unconditional consideration of the specifics of local financial markets as the basis for the formation of a banking union and a union of the capital market of the European Union.

description: Angle-resolved photoemission spectroscopy (ARPES) is used to study the spectral function of the optimally doped high-T$_c$ superconductor (Bi,Pb)$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ in the vicinity of the antinodal point in the superconducting state. Using a parameterized self-energy function, it was possible to describe both the coherent and the incoherent spectral weight of the bonding and the antibonding band. The renormalization effects can be assigned to a very strong coupling to the magnetic resonance mode and at higher energies to a bandwidth renormalization by a factor of two, probably caused by a coupling to a continuum. The present reevaluation of the ARPES data allows to come to a more reliable determination of the value of the coupling strength of the charge carriers to the mode. The experimental results for the dressing of the charge carriers are compared to theoretical models.
