description: Οι ρητίνες ουρίας-φορμαλδεΰδης (UF) είναι από τις πλέον διαδεδομένες στην βιομηχανία μοριοσανίδων. Σε προηγούμενες εργασίες αναδείχθηκε η σημαντική ενίσχυση των μηχανικών ιδιοτήτων των συγκεκριμένων ρητινών όταν σε αυτές προστίθεται μικρή ποσότητα νανοσωματιδίων SiO2. Συνεπώς κρίθηκε σκόπιμο να χαρακτηριστούν και να μελετηθούν σε βάθος τα συγκεκριμένα συστήματα, ούτως ώστε να μπορεί σε επόμενο στάδιο να ερμηνευτεί αυτή τους η συμπεριφορά. Στην παρούσα εργασία μελετήθηκε με Διαφορική Θερμιδομετρία Σάρωσης (DSC) η διαδικασία δικτύωσης συστημάτων UF ρητίνης με πρόσθετα νανοσωματίδια SiO2, τα οποία παρασκευάστηκαν από την CHIMAR Hellas σε διάφορες στοιχειομετρίες. Επίσης υπολογίστηκαν οι ενέργειες ενεργοποίησης των μετασχηματισμών αυτών για όλα τα συστήματα με εφαρμογή της μεθόδου Kissinger. Ακόμη, εξετάστηκε η επίδραση διαφόρων παραγόντων, όπως η υγρασία στο εσωτερικό των σύνθετων αυτών υλικών, η αποθήκευσή τους σε περιβάλλον ψύξης και η ανάμιξή τους με ξυλοτεμαχίδια στην θερμική συμπεριφορά τους. Επίσης μελετήθηκε η επίδραση του είδους του δειγματοφορέα στην μελέτη των θερμικών ιδιοτήτων των συγκεκριμένων υλικών. Τέλος, τα μίγματα που παρασκευάστηκαν χαρακτηρίστηκαν με Φασματοσκοπία Υπερύθρου με Μετασχηματισμούς Fourier (FTIR), Ηλεκτρονική Μικροσκοπία Σάρωσης (SEM-EDS) και Περίθλαση Ακτίνων Χ (XRD).
description: Urea-Formaldehyde (UF) resins are poly-condensation products of the reaction of formaldehyde with urea. They are the most commonly used adhesives in the wood-based panel industry due to their low cost, high reactivity and good performance. The addition of SiO2 nanoparticles in UF resins enhances the resin’s mechanical properties and therefore, needs to be studied in depth. In this work, the curing reactions of mixtures of UF resins with different amounts of SiO2 nanoparticles are being examined with Differential Scanning Calorimetry (DSC). Additionally the Activation Energy of these reactions was determined for every composite using Kissinger’s method. Also, the effects on the thermal behavior of the composites of some external factors, such as the humidity inside the systems, the storage in a freezer for a long time and the interactions with wood particles, were examined. During this work, the effect of the crucible type was also examined. Furthermore, the new composites are being characterized with Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy with associated Energy Dispersive X-ray Spectrometer (SEM/EDS) and powder X-ray Diffractometry (XRD).

description: Recent resolutions passed by the International Astronomical Union (IAU) on astronomical reference systems, time scales, and Earth rotation models are the most significant set of international agreements in positional astronomy in several decades. These resolutions, the result of over ten years of international research and study, provide a coherent set of foundational standards for the treatment of astrometric data and the modeling of dynamics in the solar system. This circular explains these resolutions and provides a complete set of practical formulas for their implementation. The six main chapters cover relativity, time scales, the fundamental celestial reference system, ephemerides of solar system bodies, precession and nutation, and modeling the Earth's rotation.

description: One of the challenges for international companies is to manage multicultural environments effectively. Cultural intelligence (CQ) is a soft skill required of the leaders of organizations working in cross-cultural contexts to be able to communicate effectively in such environments. On the other hand, organizational structure plays an active role in developing and promoting such skills in an organization. Therefore, this study aimed to investigate the effect of leader CQ on organizational performance mediated by organizational structure. To achieve the objective of this research, first, conceptual models and hypotheses of this research were formed based on the literature. Then, a quantitative empirical research design using a questionnaire, as a tool for data collection, and structural equation modeling, as a tool for data analysis, was employed among executives of knowledge-based companies in the Science and Technology Park, Bushehr, Iran. The results disclosed that leader CQ directly and indirectly (i.e., through the organizational structure) has a positive and significant effect on organizational performance. In other words, in organizations that operate in a multicultural environment, the higher the level of leader CQ, the higher the performance of that organization. Accordingly, such companies are encouraged to invest in improving the cultural intelligence of their leaders to improve their performance in cross-cultural environments, and to design appropriate organizational structures for the development of their intellectual capital.

description: In recent years, there appeared a considerable interest in the inverse spectral theory for functional-differential operators with constant delay. In particular, it is well known that specification of the spectra of two operators $\ell_j,$ $j=0,1,$ generated by one and the same functional-differential expression $-y''(x)+q(x)y(x-a)$ under the boundary conditions $y(0)=y^{(j)}(π)=0$ uniquely determines the complex-valued square-integrable potential $q(x)$ vanishing on $(0,a)$ as soon as $a\in[π/2,π).$ For many years, it has been a challenging {\it open question} whether this uniqueness result would remain true also when $a\in(0,π/2).$ Recently, a positive answer was obtained for the case $a\in[2π/5,π/2).$ In this paper, we give, however, a {\it negative} answer to this question for $a\in[π/3,2π/5)$ by constructing an infinite family of iso-bispectral potentials. Some discussion on a possibility of constructing a similar counterexample for other types of boundary conditions is provided, and new open questions are outlined.

description: We report on observations of the active K2 dwarf $ε$ Eridani based on contemporaneous SPIRou, NARVAL, and TESS data obtained over two months in late 2018, when the activity of the star was reported to be in a non-cyclic phase. We first recover the fundamental parameters of the target from both visible and nIR spectral fitting. The large-scale magnetic field is investigated from polarimetric data. From unpolarized spectra, we estimate the total magnetic flux through Zeeman broadening of magnetically sensitive nIR lines and the chromospheric emission using the CaII H & K lines. The TESS photometric monitoring is modeled with pseudo-periodic Gaussian Process Regression. Fundamental parameters of $ε$ Eridani derived from visible and near-infrared wavelengths provide us with consistent results, also in agreement with published values. We report a progressive increase of macroturbulence towards larger nIR wavelengths. Zeeman broadening of individual lines highlights an unsigned surface magnetic field $B_{\rm mono} = 1.90 \pm 0.13$ kG, with a filling factor $f = 12.5 \pm 1.7$% (unsigned magnetic flux $Bf = 237 \pm 36$ G). The large-scale magnetic field geometry, chromospheric emission, and broadband photometry display clear signs of non-rotational evolution over the course of data collection. Characteristic decay times deduced from the light curve and longitudinal field measurements fall in the range 30-40 d, while the characteristic timescale of surface differential rotation, as derived through the evolution of the magnetic geometry, is equal to $57 \pm 5$ d. The large-scale magnetic field exhibits a combination of properties not observed previously for $ε$ Eridani, with a surface field among the weakest previously reported, but also mostly axisymmetric, and dominated by a toroidal component.

description: In order to diagnose the cause of some defects in the category of canonical hypergroups, we investigate several categories of hyperstructures that generalize hypergroups. By allowing hyperoperations with possibly empty products, one obtains categories with desirable features such as completeness and cocompleteness, free functors, regularity, and closed monoidal structures. We show by counterexamples that such constructions cannot be carried out within the category of canonical hypergroups. This suggests that (commutative) unital, reversible hypermagmas -- which we call mosaics -- form a worthwhile generalization of (canonical) hypergroups from the categorical perspective. Notably, mosaics contain pointed simple matroids as a subcategory, and projective geometries as a full subcategory.

description: We present analysis of the timing noise in PSR J1733-3716, which combines data from Parkes 64-m radio telescope and nearly 15 years of timing data obtained from the Nanshan 25-m radio telescope. The variations in the spin frequency and frequency derivative are determined. The fluctuation in the spin frequency is obvious with an amplitude of 1.94(7)*10 -9 Hz. Variations of the integrated profile at 1369 MHz are detected with the changes occur in the relative peak intensity from the right profile component. From analysis of the single pulse data at 1382 MHz, we detect weak emission states that account for 63% of the whole data, and its duration distribution can be fitted with a power law. The pulsar also exhibits strong emission states, during which the emission shows multiple modes. This includes the normal mode, left mode and the right mode, with the time scales spanning between one and seventeen pulse periods. Such short term variability in pulses contributes to the variation of the integrated profile. Examination of the correlations between the spin parameters and the integrated profiles shows likelihood of a random distribution, which reveals that there is probably no obvious relationship between spin-down rate variations and changes of emission in this pulsar.

description: Cyberspace hosts abundant interactions between users and different kinds of objects, and their relations are often encapsulated as bipartite graphs. Detecting user community in such heterogeneous graphs is an essential task to uncover user information needs and to further enhance recommendation performance. While several main cyber domains carrying high-quality graphs, unfortunately, most others can be quite sparse. However, as users may appear in multiple domains (graphs), their high-quality activities in the main domains can supply community detection in the sparse ones, e.g., user behaviors on Google can help thousands of applications to locate his/her local community when s/he uses Google ID to login those applications. In this paper, our model, Pairwise Cross-graph Community Detection (PCCD), is proposed to cope with the sparse graph problem by involving external graph knowledge to learn user pairwise community closeness instead of detecting direct communities. Particularly in our model, to avoid taking excessive propagated information, a two-level filtering module is utilized to select the most informative connections through both community and node level filters. Subsequently, a Community Recurrent Unit (CRU) is designed to estimate pairwise user community closeness. Extensive experiments on two real-world graph datasets validate our model against several strong alternatives. Supplementary experiments also validate its robustness on graphs with varied sparsity scales.

Allegories of the postmodern: the work of Wilfred Watson and R. Murray Schafer
Creators: name: Haag, Stefan
Publisher: name: University of British Columbia
Year: 2009

description: The characteristic doubling of postmodern works of art is best seen in terms of an allegorical gesture that melancholics undertake in order to create life in an entity they consider dead and meaningless. Walter Benjamin has theorized the allegorical gesture and provides a basis for extending his understanding of modern allegory to the postmodern. The postmodern can be seen as a continuum that at its two extremes veers towards a deconstructive and a reconstructive impulse, respectively. While the former decentres meaning and authority, the latter reconstructs the two on the basis of an arbitrary allegorical construct that relies itself on audience belief which is generated in participatory rituals. Watson and Schafer exemplify the interdependencies of these two postmodern impulses and their emblematical qualities. Furthermore, they illustrate how melancholics view the world, how they imbue their works with a political agenda, and how they try to indoctrinate their audiences. Ultimately, the allegorical construct is as ideological as what it brutally replaces. An outward sign of the violence that is at the root of the allegorical gesture can be seen in the many acts of violence in Watson and Schafer. Watson’s project ends in ambiguity because he ironically subverts his own authority so that the audience is left mocking the allegorical “message.” Schafer, on the other hand, represses the challenge that this violence poses to his allegorical construct. Although he does not realize it, his work remains caught in ideology. Reconstructive postmodernism, as far as it depends on the author(ity) of allegory, is thus built on a validating act of the audience, which is a leap of faith rooted in ideology.

The mechanism of the rectification is discussed in terms of the spin torque diode effect reported for magnetic tunnel junction devices and the rectification is shown to be direct attributable to resonant spin wave excitation by the RF current.

description: It was recently found that, when linearised in the absence of matter, 58 cases of the general gravitational theory with quadratic curvature and torsion are (i) free from ghosts and tachyons and (ii) power-counting renormalisable. We inspect the nonlinear Hamiltonian structure of the eight cases whose primary constraints do not depend on the curvature tensor. We confirm the particle spectra and unitarity of all these theories in the linear regime. We uncover qualitative dynamical changes in the nonlinear regimes of all eight cases, suggesting at least a broken gauge symmetry, and possibly the activation of negative kinetic energy spin-parity sectors and acausal behaviour. Two of the cases propagate a pair of massless modes at the linear level, and were interesting as candidate theories of gravity. However, we identify these modes with vector excitations, rather than the tensor polarisations of the graviton. Moreover, we show that these theories do not support a viable cosmological background.

description: Stereo vision is a growing topic in computer vision due to the innumerable opportunities and applications this technology offers for the development of modern solutions, such as virtual and augmented reality applications. To enhance the user's experience in three-dimensional virtual environments, the motion parallax estimation is a promising technique to achieve this objective. In this paper, we propose an algorithm for generating parallax motion effects from a single image, taking advantage of state-of-the-art instance segmentation and depth estimation approaches. This work also presents a comparison against such algorithms to investigate the trade-off between efficiency and quality of the parallax motion effects, taking into consideration a multi-task learning network capable of estimating instance segmentation and depth estimation at once. Experimental results and visual quality assessment indicate that the PyD-Net network (depth estimation) combined with Mask R-CNN or FBNet networks (instance segmentation) can produce parallax motion effects with good visual quality.

description: A magnetic field is generally considered to be incompatible with superconductivity as it tends to spin-polarize electrons and breaks apart the opposite-spin singlet superconducting Cooper pairs. Here, an experimental phenomenon is observed that an intriguing reemergent superconductivity evolves from a conventional superconductivity undergoing a hump-like intermediate phase with a finite electric resistance in the van der Waals heterointerface of layered NbSe2 and CrCl3 flakes. This phenomenon merely occurred when the applied magnetic field is parallel to the sample plane and perpendicular to the electric current direction as compared to the reference sample of a NbSe2 thin flake. The strong anisotropy of the reemergent superconducting phase is pointed to the nature of the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state driven by the strong interfacial spin-orbit coupling between NbSe2 and CrCl3 layers. The theoretical picture of FFLO state nodes induced by Josephson vortices collectively pinning is presented for well understanding the experimental observation of the reemergent superconductivity. This finding sheds light on an opportunity to search for the exotic FFLO state in the van der Waals heterostructures with strong interfacial spin-orbit coupling.

Metrics such as quality control scores, in-frame status or filter thresholds were plotted when available. In cases where the same fusion was identified more than once within the same sample, a unique numbering scheme was added at the end of the name to differentiate the candidate fusions. The numbering however, does not imply any special order or preference over the other fusions with the same name. The putative detected fusions were arranged in decreasing order based on the number of fusion-supporting reads. The expected fusion for each sample was highlighted in bold.
Modulation of the MHC class I antigen processing and presentation pathway
Creators: name: Lippé, Roger

description: Antigen processing and presentation are central to the complex immune response elicited upon infections by pathogens. They result in the generation of peptides that can be presented to T cells and elicit specific immune responses. Two distinct pathways process and present foreign antigens and are respectively mediated through MHC class I and class II molecules. Although much has been learned about these pathways in recent years, their details remain to be resolved. The present study further examines the MHC class I pathway. To this end, two distinct approaches were undertaken. First, we examined the ability of Adenovirus type 2 to block this pathway. Thus far, this phenotype had solely been attributed to the E3/19K viral protein. Since past characterizations were unexpectedly done in the presence of other viral proteins, including E3/6.7K, we sought to determine the role of E3/6.7K on this phenotype and to further characterize its properties. Using a bank of viral deletion mutants, lacking either E3/6.7K or E3/19K, we found a specific interaction between E3/6.7K and E3/19K. Despite this interaction, E3/6.7K did not affect MHC class I surface expression or phosphorylation. However, we report the novel finding that at least one additional viral protein was necessary for the optimal down regulation of MHC class I surface expression by the virus. Unexpectedly, the detection of disulfide bonds in E3/6.7K suggested that it likely had a peculiar orientation in the ER membrane. In the second approach, we examined the ability of a mutant cell line, gro29, deficient for HSV-1 viral egress, to process and present peptides to T cells. The results indicated that gro29 had a slight, but likely inconsequential, deficiency in the processing of molecules through its secretory pathway and had a normal complement of proteins at its surface. Surprisingly, this mutant was deficient for the presentation of HSV-1 peptides, but normally processed and presented allogeneic and Influenza peptides. Most important, this dichotomy indicated the existence of distinct MHC class I processing and presentation pathways. Overall the data revealed a complex interaction between Adenovirus type 2 and the MHC class I processing and presentation pathway. They also underlined the usefulness of the gro29 variant cell line as mutant antigen processing and presentation cells.

description: In this paper we present a statistical study of the kinematics of 28894 coronal mass ejections (CMEs) recorded by the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory spacecraft from 1996 until mid-2017. The initial acceleration phase is characterized by a rapid increase in CME velocity just after eruption in the inner corona. This phase is followed by a non-significant residual acceleration (deceleration) characterized by an almost constant speed of CMEs. We demonstrate that the initial acceleration is in the range 0.24-2616 ms-2 with median (average) value of 57 ms-2 (34 ms-2 ) and it takes place up to a distance of about 28 solar radius with median (average) value of 7.8 solar radius (6 solar radius). Additionally, the initial acceleration is significant in the case of fast CMEs (V > 900 kms-1 ), where the median (average) values are about 295 ms-2 (251 ms-2 ), respectively, and much weaker in the case of slow CMEs (V < 250 kms-1 ), where the median (average) values are about 18 ms-2 (17 ms-2 ), respectively. We note that the significant driving force (Lorentz force) can operate up to a distance of 6 solar radius from the Sun during the first 2 hours of propagation. We found a significant anti-correlation between the initial acceleration magnitude and the acceleration duration, whereas the residual acceleration covers a range from -1224 to 0 ms-2 with a median (average) value of -34 ms-2 (-17 ms-2 ). One intriguing finding is that the residual acceleration is much smaller during the 24th cycle in comparison to the 23rd cycle of solar activity. Our study has also revealed that the considered parameters, initial acceleration (ACC INI ), residual acceleration (ACC RES ), maximum velocity (V MAX ), and time at maximum velocity (Time MAX ) mostly follow solar cycles and the intensities of the individual cycle.

description: A quantum walk, \emph{i.e.}, the quantum evolution of a particle on a graph, is termed \emph{scalar} if the internal space of the moving particle (often called the coin) has a dimension one. Here, we study the existence of scalar quantum walks on Cayley graphs, which are built from the generators of a group. After deriving a necessary condition on these generators for the existence of a scalar quantum walk, we present a general method to express the evolution operator of the walk, assuming homogeneity of the evolution. We use this necessary condition and the subsequent constructive method to investigate the existence of scalar quantum walks on Cayley graphs of various groups presented with two or three generators. In this restricted framework, we classify all groups -- in terms of relations between their generators -- that admit scalar quantum walks, and we also derive the form of the most general evolution operator. Finally, we point out some interesting special cases, and extend our study to a few examples of Cayley graphs built with more than three generators.

title: A fusion protein based pneumococcal vaccine

description: The Gram-positive bacterium Streptococcus pneumoniae(pneumococcus) is a major human pathogen, causing Otitis media, pneumonia, bacteraemia and meningitis worldwide. There are over 90 different serotypes of pneumococcus
and current pneumococcal vaccines are somewhat limited in their protection against pneumococcal diseases. Currently available vaccines are based on the capsular polysaccharide. The 23-valent polysaccharide (PSP) vaccine can protect most of adults and children older than five, but it cannot protect children under age 2, immunodeficiency patients and cannot protect the elderly very well. The polysaccharide/ protein conjugated vaccines which are complementary to the 23-valent PS vaccine have been introduced. The PSP conjugate vaccine is highly
immunogenic and protects children under the age of 2 and immunodeficiency patients against invasive pneumococcal diseases, but its efficacy is threatened by strain replacement and serotype switching since it only protects against the limited number of serotypes contained within the vaccine. There is therefore a need to develop improved vaccines against pneumococcal diseases.

Pneumolysin (PLY), a cholesterol dependent cytolysin and an important virulence factor of pneumococcus, can act as a powerful mucosal adjuvant to induce both systemic and mucosal immunity to proteins genetically fused to PLY. Which
regions of PLY are required for the novel adjuvant activity is not currently known. The model antigen eGFP was fused to domain 1-3 of PLY (D123PLY) and domain 4 of PLY (D4PLY) by ligation-dependent DNA recombinant technology during my master project. Balb/c mice were intranasally immunised with
purified eGFPD4PLY or eGFPD123PLY fusion protein and immune response were then monitored by enzyme linked immunosorbent assay (ELISA). The ELISA data shows truncated PLY lost the adjuvant property and this adjuvant property was
restored in the presence of free PLY or A6PLY when antigen was fused with truncated PLY. The aim of the current work is to determine whether a fusion protein based pneumococcal vaccine can be developed to provide protection against three
pneumococcal strains in animal models of colonisation and invasive diseases. For this purpose, pneumococcal virulence factors, PsaA, PspA, PspC and PhtD were genetically fused to PLY or Δ6PLY separately by In-fusion cloning technology.
Δ6PLY is a toxoid that lacks haemolytic activity but retains the immunogenic and adjuvant activity of PLY. MF1 mice were then vaccinated either intranasally or subcutanously by purified fusion protein antigens and immune responses were also monitored by ELISA; vaccinated mice were finally challenged intranasally by three strains of pneumococcus and monitored for colonisation. The immunity
elicited by pneumococcal antigens fused to PLY/Δ6 PLY is protective in a colonisation model.

description: We study the topological entropy of Reeb flows on contact manifolds with Liouville fillings. With the theory of persistence modules, we define SH-barcode entropy from the symplectic homology of a filling. We prove that the SH-barcode entropy is independent of the choice of the filling and that the barcode entropy provides a lower bound for the topological entropy of the Reeb flow.

description: Photoinduced non-thermal phase transitions are new paradigms of exotic non-equilibrium physics of strongly correlated materials. An ultrashort optical pulse can drive the system to a new order through complex microscopic interactions that do not occur in the equilibrium state. Ultrafast spectroscopies are unique tools to reveal the underlying mechanisms of such transitions which lead to transient phases of matter. Yet, their individual specificities often do not provide an exhaustive picture of the physical problem. One effective solution to enhance their performance is the integration of different ultrafast techniques. This provides an opportunity to simultaneously probe physical phenomena from different perspectives whilst maintaining the same experimental conditions. In this context, we performed complementary experiments by combining time-resolved reflectivity and time and angle-resolved photoemission spectroscopy. We demonstrated the advantage of this combined approach by investigating the complex charge density wave (CDW) phase in 1$\it{T}$-TiSe$_{2}$. Specifically, we show the key role of lattice degrees of freedom to establish and stabilize the CDW in this material.
