description: We consider the spin-1/2 antiferromagnetic Heisenberg chain in a staggered magnetic field describing materials such as copper benzoate and copper pyrimidine dinitrate. Using the density-matrix renormalization group for transfer matrices (TMRG) we calculate the magnetization of these materials at finite temperature and arbitrary magnetic field. These results are in excellent agreement with experimental data, allowing for a determination of the inhomogeneity parameter c of copper benzoate (c = 0.043) and copper pyrimidine dinitrate (c= 0.11). The TMRG approach can be applied to rather low temperatures yielding singular field and temperature dependences of susceptibilities.

description: Α new type of large-sized glass tubes has been developed by laminating a load bearing inner core tube with protecting and supporting outer half shells. Additionally, for high loads to be transferred, the eontaet zone between glass and support material has been studied. The result is - contrary to common judgment - that in this ease the permissible stretching strain of the support material should be higher than the compressive stress to be transferred. In this way laminated glass tubes meet the essential requirements of architecture and civil engineering by: - tolerating high compressive stress (up to 60 MPa) without any failure, - maintaining high residual strength under load even after serious damage. It is hoped that the structural suitability of glass will be noticed by technicians and that this will succeed in reducing the reservations that still exist vis-a-vis this attractive, high-calibrated material. It gives not just architects, but civil engineers, interior designers, lighting specialists and others a new perspective, enabling them to design and build more transparent, more elegant and hopefully lighter-weight structures.
Comparative analysis of community and population levels of organization in the rare grass, Achnatherum hendersonii

description: Studies of rarity tend to focus on the population level of the species in question. A complete understanding of rarity however, requires understanding both population and community patterns and processes. To that end, population and community levels of organization were compared in the rare grass, Achnatherum hendersonii. Achnatherum hendersonii occurs in small, local populations in central Washington and north-central Oregon. I compared sympatric and disjunct populations of A. hendersonii from its northern and southern distribution limits. I also compared A. hendersonii with the closely related common grass, A. lemmonii. Plant species coverage in vegetation plots was used to estimate community level organization, and morphology of inflorescence and vegetative leaves was used to estimate population level organization. Principal components analysis (PCA) was used to make comparisons. Organization was assessed through the calculation of 95% confidence level bivariate ellipses about the first two PCA axis scores. The ellipse statistics theta, eccentricity, and area were used to quantify three components of organization for each group: theta reflects the covariance or organization sensu stricto; eccentricity reflects the strength of correlation or organization as order; area relates to the amount of variation. Community level organization differed throughout the distribution range of A. hendersonii. At the northern distribution limit, variation in the vegetation was less for the rare grass than the common grass, however, in the southern limit A. hendersonii vegetation had the greatest overall variation. In the southern end of the distribution range, variation in the vegetation was influenced by the coverage of cryptogamic crust. Population level organization was similar throughout the distribution range of A. hendersonii. Achnatherum hendersonii morphology was congruent within and among populations. There was less morphological variation in Achnatherum hendersonii than A. lemmonii. Overall, community and population levels of organization were dissimilar. Comparisons of community and population levels organization of rare species increases our theoretical understanding of biological organization, by increasing our power of examination. In this case, they reveal different responses by the plant as compared with its vegetation. This different response argues for different causal agents affecting morphology and vegetation.

By relying on the method of random averaging operators in arXiv:1910.08492, we show that there exists $\frac{1}{2} \ll β_0 <1 $ such that for $ β> β_0 $ we have invariance of the associated Gibbs measure and global existence of strong solutions in its statistical ensemble. In this way we extend Bourgain's seminal result [7] which requires $β>2$ in this case.

Effects of heating and aluminum content on the dissolution of magnesium-rich amorphous silicate fibers in a simple amino acid solution
Creators: name: Ohsawa, Masato
Publisher: name: Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft
Year: 2004
Subjects: subject: 660

description: This study suggests that heat treatment around 700 °C increases the dissolution rate of Mg-rich and Al-free amorphous alkaline earth silicate (AES) fibers, which are designed to be biosoluble, in a simple amino acid solution. The dissolution experiments of Mg-rich AES fibers in the Al-free and Al-bearing systems heat-treated in the temperature range from 110 to 1260 °C were carried out in a glycine, a simple amino acid, solution. These experiments show that the dissolution rate of the Al-free AES fibers in the glycine solution is rising sharply with increasing heat treatment temperature and reaches its maximum around 700 °C. The sharp rise in the dissolution rate is assumed to be due to the formation of chemically less durable phases caused by phase separation resulting from the heat treatment. These chemically less durable phases may be preferentially attacked by glycine ions. In contrast, the heat treatment around 700 °C brought no increase in the dissolution rate for the Al-bearing AES fibers. This is due to the fact that small amounts of AI2O3 can change the internal glass structure and lead to retardation of the dissolution process.

description: In this paper we calculate analytically the perturbative matching coefficients for unpolarized quark and gluon Transverse-Momentum-Dependent (TMD) Parton Distribution Functions (PDFs) and Fragmentation Functions (FFs) through Next-to-Next-to-Next-to-Leading Order (N$^3$LO) in QCD. The N$^3$LO TMD PDFs are calculated by solving a system of differential equation of Feynman and phase space integrals. The TMD FFs are obtained by analytic continuation from space-like quantities to time-like quantities, taking into account the probability interpretation of TMD PDFs and FFs properly. The coefficient functions for TMD FFs exhibit double logarithmic enhancement at small momentum fraction $z$. We resum such logarithmic terms to the third order in the expansion of $α_s$. Our results constitute important ingredients for precision determination of TMD PDFs and FFs in current and future experiments.

description: In a series of papers, we have recently demonstrated that it is possible to construct stellar structure models that robustly mimic the stratification of multi-dimensional radiative magneto-hydrodynamic simulations at every time-step of the computed evolution. The resulting models offer a more realistic depiction of the near-surface layers of stars with convective envelopes than parameterizations, such as mixing length theory, do. In this paper, we explore how this model improvement impacts on seismic and non-seismic properties of stellar models across the Hertzsprung-Russell diagram. We show that the improved description of the outer boundary layers alters the predicted global stellar properties at different evolutionary stages. In a hare and hound exercise, we show that this plays a key role for asteroseismic analyses, as it, for instance, often shifts the inferred stellar age estimates by more than 10 per cent. Improper boundary conditions may thus introduce systematic errors that exceed the required accuracy of the PLATO space mission. Moreover, we discuss different approximations for how to compute stellar oscillation frequencies. We demonstrate that the so-called gas $Γ_1$ approximation performs reasonably well for all main-sequence stars. Using a Monte Carlo approach, we show that the model frequencies of our hybrid solar models are consistent with observations within the uncertainties of the global solar parameters when using the so-called reduced $Γ_1$ approximation.

description: One of the possible defects in sputter coating layers are cone shaped rods which originate from the float glass surface on the atmosphere side. The glass surface had been etched by wax-like corrosion droplets and holes were formed into the glass skin after washing. This results in inhomogeneity on the surface, which induces an inhomogenous deposition pattern of the material on the surface during the process of sputtering. In contrast, the tin bath side is shown to be an ideal coating surface without any inhomogen eity. In some eases however, it could not be bent above the glass transition temperature (Tg) in air due to formation of bloom patterns, which make the glass milky. Our studies revealed that phase separation is the ultimate cause of the observed bloom formation. In addition, sulphur flakes and needle-like nanocrystallites were detected on the tin bath side as well as hexagonal nanocrystallites on the atmosphere side of the annealed float glass. It was also found that flame treatment of borosilieate and lead crystal glasses induced two changes on the glass surfaces. These are precipitation of evaporation products and phase separation beneath the glass skin. The samples were studied by a combination of field emission scanning electron microscopy (FE-SEM) with different accelerating voltages and atomic force microscopy (AFM).

description: Glasses in the system Na2O-Al2O3-B2O3-SiO2 were melted from the raw materials and studied with respect to their chemical durability, their crystal growth velocities, their refractive index and dispersion, their glass transition temperature and their thermal expansion coeffieient. With inereasing Na2O concentration, the crystal growth velocity increases and the chemical durability decreases. Equimolar subtitution of B2O3 for SiO2 results in a decrease in both the chemical durability and in crystal growth velocities. Equimolar subtitution of AI2O3 for SiO2 leads to increasing chemical durability and decreasing crystal growth velocities. Optimum glass compositions to produce gradient index lenses should possess B2O3 concentrations of around 12.5 to 15 mor% and molar AI2O3 concentrations some percent larger than the Na2O concentration. In these glasses, nonbridging oxygen does not occur.

The praetorian guard in the political and social life of Julio-Claudian Rome
Creators: name: Bingham, Sandra J.
Publisher: name: University of British Columbia
Year: 2009

description: The imperial praetorian guard was an elite unit of the Roman army, whose primary responsibility was to safeguard the emperor and his family. Adapted from a republican institution by Augustus, it in essence formed the personal army of the emperor. Yet, within a very short time, the praetorians became responsible for specialized military tasks involving issues of security, and for various administrative duties in Rome. This evolution occurred primarily because of the close relationship between the guard and the emperor, who saw that such a large number of soldiers in the city could be put to good use for his own benefit, and for the advantage of the state. Not only would they assist in the management of the capital, they also would serve as a constant reminder to the populace of the substantial armed force that formed the basis of imperial rule. Previous studies of the guard have concentrated on its organization and role as the imperial bodyguard. Yet it is through an examination of the other responsibilities of the praetorians that a more comprehensive understanding of their position in the state can be deduced. The purpose of the present study is to examine those aspects of the guard that are outside its basic mandate of providing protection for the imperial household. The development of the praetorians into a unit that carried out political espionage, fought fires in the city, and was employed as security at the games provides insight into the nature of the early principate, which relied on armed force to maintain its authority. The expanded role of the guard in the Julio-Claudian period can be viewed as the deliberate integration of the military into the fabric of Roman administration. By placing soldiers who owed their allegiance only to him in key roles in the capital, the emperor was able to consolidate his hold on power while, at the same time, often providing much needed services that benefited the state as a whole.

description: The crystallization of some glasses within the binary spodumene(LiAlSi2O6)-nepheline(NaAlSiO4) system with and without TiO2 has been investigated using X-ray diffraction analysis, scanning electron microscopy and coefficient of thermal expansion (CTE) measurements. The crystalline phases developed were β-spodumene, β-eucryptite, LAS(Li2Al2Si2O8), nepheline, carnegieite, quartz and cristobalite. Crystallization of TiO2-free glasses was relatively dependent on the nominal ratio and the heat treatments as well, however, the lithium aluminosilicate phases were usually dominant. TiO2 catalyzed the aluminosilicate phases and precluded the crystallization of silica phases. Inversion of nepheline into carnegieite took place at higher temperatures in TiO2-free samples, however, carnegieite was also developed in small amounts in TiO2 containing samples. On the other band, the β-eucryptite resisted the entire inversion into β-spodumene even at higher temperatures (up to 1100 °C). Glass-ceramics of heterogeneous microstructures were obtained. The CTE values of the glasses investigated decrease from 101 to 86 ∙ 10^-7 K (20 to 500 °C) with increase in the Li2O/Na2O ratio, and those of the corresponding glass-ceramics decrease from 96 to -24 ∙ 10^-7 K^-1 (20 to 500 °C) with increase in the crystallization of β-eucryptite and/or β-spodumene.

description: As Latinx student enrollment increases across higher education, in particular at community colleges, there is a trend of community colleges emerging as Hispanic Serving Institutions (HSIs). Although many institutions gain a HSI designation, critiques from scholars around how institutions demonstrate “servingness” continue to transpire, especially when taking into consideration queer Latinx students. This article utilizes an environmental scan of community colleges that form part of the Southern California Consortium of Hispanic Serving Institutions (SCCHSI) to further explore the need for more holistic and intersectional support for Latinx students at HSI community colleges. The authors provide recommendations around grant writing; impact of emerging and continuing HSIs; the importance of leadership representation; how alignment with campus, district, and state initiatives contribute to Latinx success; and LGBTQ+ services and professional learning.

description: A family of LDPC codes, called LU(3,q) codes, has been constructed from q-regular bipartite graphs. Recently, P. Sin and Q. Xiang determined the dimensions of these codes in the case that q is a power of an odd prime. They also obtained a lower bound for the dimension of an LU(3,q) code when q is a power of 2. In this paper we prove that this lower bound is the exact dimension of the LU(3,q) code. The proof involves the geometry of symplectic generalized quadrangles, the representation theory of Sp(4,q), and the ring of polynomials.

description: The model glasses NBS1 and NBS2 are sodium borosilicate glasses of high intrinsic UV transmission. Although both glasses have an SiO2 content of 74 mol%, they possess different matrix structures due to varied Na2O / B2O3 ratios. Nonbridging oxygens occur in the NBS1 but not in the NBS2 glass. Fe, Ti and Sb oxides were added at concentrations of 1 and 10mol% to study valence, coordination and site distribution. XANES, Mössbauer, optical absorption, photoluminescence and EPR spectroscopy provided an insight into the structures and near range environments of the dopants. Large differences were found for the two Fe doped glasses. The presence of nonbridging oxygens in NBS1 glass leads to a higher solubility of the Fe ions and a higher ratio of tetrahedral over octahedral Fe3+ coordination while a clustering of Fe ions resulting in a lowered UV and VIS transmission is observed in NBS2 glass. In Ti doped glasses EPR and XANES spectroscopy shows that most Ti occurs as Ti4+, in four-, five- and sixfold coordination. Optical spectra of Ti4+ display high intensity charge transfer transitions in the UV region. Ti4+ photoluminescence in the visible range is of low intensity. Optical absorption, XANES and Mössbauer spectroscopy could only detect Sb3+ in the antimony doped glasses. The photoluminescence of Sb3+ is much stronger in the NBS1 than in the NBS2 glass.

description: Due to the peculiar properties of ultra-diffuse galaxies (UDGs), understanding their origin presents a major challenge. Previous X-ray studies demonstrated that the bulk of UDGs lack substantial X-ray emission, implying that they reside in low-mass dark matter halos. This result, in concert with other observational and theoretical studies, pointed out that most UDGs belong to the class of dwarf galaxies. However, a subset of UDGs is believed to host a large population of globular clusters (GCs), which is indicative of massive dark matter halos. This, in turn, hints that some UDGs may be failed $L_{\star}$ galaxies. In this work, I present Chandra and XMM-Newton observations of two archetypal UDGs, Dragonfly 44 and DF X1, and I constrain their dark matter halo mass based on the X-ray emission originating from hot gaseous emission and from the population of low-mass X-ray binaries residing in GCs. Both Dragonfly 44 and DF X1 remain undetected in X-rays. The upper limits on the X-ray emission exclude the possibility that these galaxies reside in massive ($M_{\rm vir} \gtrsim 5\times10^{11} \ \rm{M_{\odot}}$) dark matter halos, suggesting that they are not failed $L_{\star}$ galaxies. These results demonstrate that even these iconic UDGs resemble to dwarf galaxies with $M_{\rm vir} \lesssim 10^{11} \ \rm{M_{\odot}}$, implying that UDGs represent a single galaxy population.

description: The "blazar sequence" posits that the most powerful BL Lacertae objects and flat-spectrum radio quasars should have relatively small synchrotron peak frequencies, nu_peak, and that the least powerful such objects should have the highest nu_peak values. This would have strong implications for our understanding of jet formation and physics and the possible detection of powerful, moderately high-redshift TeV blazars. I review the validity of the blazar sequence by using the results of very recent surveys and compare its detailed predictions against observational data. I find that the blazar sequence in its simplest form is ruled out. However, powerful flat-spectrum radio quasars appear not to reach the nu_peak typical of BL Lacs. This could indeed be related to some sort of sequence, although it cannot be excluded that it is instead due to a selection effect.

description: Η παρούσα εργασία περιγράφει το ζήτημα του προσηλυτισμού και της θρησκευτικής ελευθερίας εν γένει. Εξετάζονται από πλευράς θεολογικής, κοινωνιολογικής και νομικής. Η θρησκευτική ελευθερία συνδέεται άμεσα με τη διδασκαλία της Εκκλησίας, αφού ο Χριστιανισμός ορίζει ως πνευματική τροφή του ανθρώπου την ελευθερία. Εξετάζεται επίσης κοινωνιολογικά, με ποιον τρόπο δηλαδή θίγεται η θρησκευτική ελευθερία στα πλαίσια της σύγχρονης παγκοσμιοποιημένης κοινωνίας. Στη συνέχεια ερευνάμε και τα νομικά κείμενα στα οποία κατοχυρώνεται η θρησκευτική ελευθερία έναντι του προσηλυτισμού. Τέλος, συμπεριλαμβάνονται ειδικότερα θέματα θρησκευτικής ελευθερίας, όπως ο όρκος, η ανέγερση ναών και ευκτηρίων οίκων, οι θρησκευτικές μειονότητες στην Ελλάδα, κ.ά.
description: This writing describes and explains the subject of proselytism and religious freedom. It has been searched theologically, sociologically and legally. The religious freedom is directly connected with the christian teaching. Sociologically we search the way, that the right of religious freedom is violated in society of today. Furthermore we investigate the legal writings and the law, which describe how religious freedom is secured in front of the danger of proselytism. Finally we include specific subjects of religious freedom, such as the erection of temples, the oath, the existence of religious minorities in Greece, etc.

Electric double layer in concentrated solutions of ionic surfactants

description: A simple non-local theoretical model is developed considering concentrated ionic surfactant solutions as regular ones. Their thermodynamics is described by the Cahn-Hilliard theory coupled with electrostatics. It is discovered that unstable solutions possess two critical temperatures, where the temperature coefficients of all characteristic lengths are discontinuous. At temperatures below the lower critical temperature ionic surfactant solutions separate into thin layers of oppositely charged liquids spread across the whole system and the electric potential is strictly periodic. At temperatures between the two critical temperatures separation can occur only near the solution surface thus leading to an oscillatory-decaying electric double layer. At temperatures above the higher critical temperature as well as in stable solutions there is no separation and the electric potential decays exponentially.

description: Representing the semantics of GUI screens and components is crucial to data-driven computational methods for modeling user-GUI interactions and mining GUI designs. Existing GUI semantic representations are limited to encoding either the textual content, the visual design and layout patterns, or the app contexts. Many representation techniques also require significant manual data annotation efforts. This paper presents Screen2Vec, a new self-supervised technique for generating representations in embedding vectors of GUI screens and components that encode all of the above GUI features without requiring manual annotation using the context of user interaction traces. Screen2Vec is inspired by the word embedding method Word2Vec, but uses a new two-layer pipeline informed by the structure of GUIs and interaction traces and incorporates screen- and app-specific metadata. Through several sample downstream tasks, we demonstrate Screen2Vec's key useful properties: representing between-screen similarity through nearest neighbors, composability, and capability to represent user tasks.

description: Α study of the ballistic impact resistance of a commercial wired glass has been undertaken using a gas gun capable of velocities up to 400 m s-1. The projectile was a steel ball and impact energies up to 7.32 J were used. The extent of the impact damage was assessed by the mass of ejected material, the area of the Hertzian cone left by the impact and residual strength. Crack morphologies similar to those reported in monolithic glasses were observed, namely ring, cone and radial cracks. The impact energy dependencies of the mass of ejected material and cone area were similar showing a rapid increase at energies above about 4.35 J. In contrast, the residual strength remained at 20 % or less of the as received wired glass irrespective of impact energy. This was attributed to the wire mesh remaining intact for the ballistic impact conditions investigated.

Synthesis and Pruning as a Dynamic Compression Strategy for Efficient Deep Neural Networks

description: The brain is a highly reconfigurable machine capable of task-specific adaptations. The brain continually rewires itself for a more optimal configuration to solve problems. We propose a novel strategic synthesis algorithm for feedforward networks that draws directly from the brain's behaviours when learning. The proposed approach analyses the network and ranks weights based on their magnitude. Unlike existing approaches that advocate random selection, we select highly performing nodes as starting points for new edges and exploit the Gaussian distribution over the weights to select corresponding endpoints. The strategy aims only to produce useful connections and result in a smaller residual network structure. The approach is complemented with pruning to further the compression. We demonstrate the techniques to deep feedforward networks. The residual sub-networks that are formed from the synthesis approaches in this work form common sub-networks with similarities up to ~90%. Using pruning as a complement to the strategic synthesis approach, we observe improvements in compression.

description: Με την παρούσα εργασία επιχειρείται η εξέταση των αφηγηματικών τεχνικών, του τρόπου με τον οποίο ο συγγραφέας Ιωάννης Καμινιάτης επιλέγει να μας παρουσιάσει την ιστορία του : την άλωση της Θεσσαλονίκης το 904 από Αραβες πειρατές και την επακόλουθη αιχμαλωσία και μεταφορά στη Συρία χιλιάδων κατοίκων της. Στην εισαγωγή δηλώνεται πως, παρά τις ενστάσεις σχετικά με τη χρονολόγηση του έργου, ο πραγματολογικός του χαρακτήρας δεν αμφισβητείται, ωστόσο, το κείμενο φανερώνει προχωρημένη αφηγηματική επεξεργασία. Η ανάλυση των αφηγηματικών τεχνικών στο κείμενο του Καμινιάτη πραγματοποιείται με γνώμονα τις σύγχρονες θεωρίες περί αφήγησης. Βασικό βοήθημα αποτελεί η σχετική πραγματεία του G. Genette, The Narrative Discourse, σχετικά με τη δομή και τιςς δυνατές μορφές αφήγησης. Προσεγγίζονται διάφορες πλευρές της αφηγηματικής λειτουργίας : η σχέση χρόνου ιστορίας-χρόνου αφήγησης, η μορφή και το περιεχόμενο της περιγραφής, οι λειτουργίες του αφηγητή στο κείμενο και η επικοινωνία του με τον αναγνώστη, η ιδεολογική επένδυση της αφήγησης, η σημασία που δίνεται στη λεπτομέρεια, η χρήση παροιμιακών και μεταφορικών εκφράσεων. Επιχειρείται, επίσης, στα πλαίσια της αφηγηματικής ανάλυσης, ένας ενδεικτικός προσδιορισμός των ποικίλων επιρροών στη συγγραφή του κειμένου από είδη γραπτού λόγου, όπως η ιστοριογραφία, η χρονογραφία, η επιστολογραφία και η ρητορική.
description: The present dissertation is concerned with narrative techniques – howwriter John Kaminiates chooses to tell his story: the capture of Thessaloniki in904 by Arab pirates and the ensuing captivation and transport of thousands ofinhabitants to Syria. As stated in the introduction, despite debate surroundingthe authorship and dating of the work, there is no question regarding itspragmatic content, whilst an advanced narrative process has obviously beenemployed. My analysis of narrative techniques is based on modern narrativetheories – G. Genette’s relevant treatise The Narrative Discourse on thestructure and possible forms of narration provides considerable reference.Various aspects of narrative function are examined: the relation between storytime and narration time, the form and content of description, the narrator’sroles and communication with the reader, the enriching of narration withideas, the significance of detail, the use of proverbs and metaphors. Finally, anindicative discussion of the influential written forms in Kaminiates’s work,such as historiography, chronography, epistolary texts and rhetoric, is alsoattempted within the framework of this narrative analysis.

The combination approximation method
Creators: name: Fang, Yuan
Publisher: name: The Australian National University
Year: 2011

description: The purpose of this thesis is to introduce the combination approximation method for the second order elliptic boundary-value problems under certain conditions. This method is developed based on the combination technique and the two-scale finite element discretization scheme. The combination approximation method has improved parallel scalabilities with a bounded resultant sacrifice of accuracy, thus strengthening the potential of grid-based methods in high-dimensional settings. Compare to the combination technique, it also has the flexibility in choosing which parts of the domain are to be partitioned into finer grids and which parts into coarser grids to suit different needs for discretizations.
