description: The exchange contribution to the energy of the hydrogen atom interacting with a proton is calculated from the polarization expansion of the wave function using the conventional surface-integral formula and two formulas involving volume integrals: the formula of the symmetry-adapted perturbation theory (SAPT) and the variational formula recommended by us. At large internuclear distances $R$, all three formulas yield the correct expression $-(2/e)Re^{-R}$, but approximate it with very different convergence rates. In the case of the SAPT formula, the convergence is geometric with the error falling as $3^{-K}$, where $K$ is the order of the applied polarization expansion. The error of the surface-integral formula decreases exponentially as $a^K/(K+1)!$, where $a=\ln2 -\tfrac{1}{2}$. The variational formula performs best, its error decays as $K^{1/2} [a^{ K}/(K+1)!]^2$. These convergence rates are much faster than those resulting from approximating the wave function through the multipole expansion. This shows the efficiency of the partial resummation of the multipole series effected by the polarization expansion. Our results demonstrate also the benefits of incorporating the variational principle into the perturbation theory of molecular interactions.

description: With the aim of understanding the coevolution of star formation rate (SFR), stellar mass (M*), and oxygen abundance (O/H) in galaxies up to redshift z=3.7, we have compiled the largest available dataset for studying Metallicity Evolution and Galaxy Assembly (MEGA); it comprises roughly 1000 galaxies with a common O/H calibration and spans almost two orders of magnitude in metallicity, a factor of 10^6 in SFR, and a factor of 10^5 in stellar mass. From a Principal Component Analysis, we find that the 3-dimensional parameter space reduces to a Fundamental Plane of Metallicity (FPZ) given by 12+log(O/H) = -0.14 log (SFR) + 0.37 log (M*) + 4.82. The mean O/H FPZ residuals are small (0.16 dex) and consistent with trends found in smaller galaxy samples with more limited ranges in M*, SFR, and O/H. Importantly, the FPZ is found to be redshift-invariant within the uncertainties. In a companion paper, these results are interpreted with an updated version of the model presented by Dayal et al. (2013).

description: The Dirichlet process and its extension, the Pitman-Yor process, are stochastic processes that take probability distributions as a parameter. These processes can be stacked up to form a hierarchical nonparametric Bayesian model. In this article, we present efficient methods for the use of these processes in this hierarchical context, and apply them to latent variable models for text analytics. In particular, we propose a general framework for designing these Bayesian models, which are called topic models in the computer science community. We then propose a specific nonparametric Bayesian topic model for modelling text from social media. We focus on tweets (posts on Twitter) in this article due to their ease of access. We find that our nonparametric model performs better than existing parametric models in both goodness of fit and real world applications.

Intrinsic parallel rotation drive by electromagnetic ion temperature gradient turbulence

description: The quasilinear intrinsic parallel flow drive including parallel residual stress, kinetic stress, cross Maxwell stress and parallel turbulent acceleration by electromagnetic ion temperature gradient (ITG) turbulence is calculated analytically using electromagnetic gyrokinetic theory. Both the kinetic stress and cross Maxwell stress also enter the mean parallel flow velocity equation via their divergence, as for the usual residual stress. The turbulent acceleration driven by ion pressure gradient along the total magnetic field (including equilibrium magnetic field and fluctuating radial magnetic field) cannot be written as a divergence of stress, and so should be treated as a local source/sink. All these terms can provide intrinsic parallel rotation drive. Electromagnetic effects reduce the non-resonant electrostatic stress force and even reverse it, but enhance the resonant stress force. Both the non-resonant and resonant turbulent acceleration terms are also enhanced by electromagnetic effects. The possible implications of our results for experimental observations are discussed.

description: As part of the Megamaser Cosmology Project (MCP), we present VLBI maps of nuclear water masers toward five galaxies. The masers originate in sub-parsec circumnuclear disks. For three of the galaxies, we fit Keplerian rotation curves to estimate their supermassive black hole (SMBH) masses, and determine (2.9 $\pm$ 0.3) $\times~10^{6}M_\odot$ for J0437+2456, (1.7 $\pm$ 0.1) $\times~10^{7}M_\odot$ for ESO 558$-$G009, and (1.1 $\pm$ 0.2) $\times~10^{7}M_\odot$ for NGC 5495. In the other two galaxies, Mrk 1029 and NGC 1320, the geometry and dynamics are more complicated and preclude robust black hole mass estimates. Including our new results, we compiled a list of 15 VLBI-confirmed disk maser galaxies with robust SMBH mass measurements. With this sample, we confirm the empirical relation of $R_{out} \propto 0.3 M_{SMBH}$ reported in Wardle & Yusef-Zadeh (2012). We also find a tentative correlation between maser disk outer radii and WISE luminosity. We find no correlations of maser disk size with X-ray 2-10 keV luminosity or [O III] luminosity.

Translatability and 20th century Korean art (1930s to 1990s)
Creators: name: Ahn, En Young
Publisher: name: Canberra, ACT : The Australian National University
Year: 2003

description: This PhD thesis is a critical inquiry into the (un) translatability of the 'difference' of an art produced in a non-'Western' context. My inquiries into the translatability of cultural differences do not deal with 'the incommensurability' of these differences, but explore the possibilities of their significant translations. This has been carried out in terms of case studies of four major Korean artists, their representative works, and the artistic developments of the 1930s-1990s in Korea. The artists in order are OH Chi Ho, PARK Seo Bo, SUH Se Ok and Kim Sooja. Each of Chapters 3 to 6 focuses on one of these artists whose work represents the most significant developments of colonial and 'postcolonial' Korean art, in reference to my theoretical arguments grounded in Chapters I and 2: the ideological and political discourses of cultural identity of a colonial and postcolonial nation's art; a marginalized nation's discourse of 'double translation' in cross-cultural transactions; and the postmodern and postcolonial concept of a 'peripheral' nation's hybridity. The term 'translation' in this thesis covers all kinds of translation: from translating the figurative to the literal, translating between different cultures and translating the past into the present. I will also use the term 'translate' as a metaphor for certain kinds of transference and dependence-linking it to Hegel's philosophy of self-consciousness and aspects of Lacan's psychoanalytic theory in order to illuminate and analyze problems involved in theorizing cultural identity and cross cultural transactions within the context of the current globalization in which geographical, economical, cultural and conceptual spaces are becoming increasingly hybrid. Throughout the thesis, Iuse the case studies of particular Korean artists as the basis of a critique of the nationalist Korean analysis of colonial and postcolonial Korean art, a postcolonial theory-inspired notion of the hybridity of an assumed peripheral culture/country (for example Korea), totalizing generalizations of 'Asianness' or 'Koreanness' of contemporary Korean art, and the Euro-centric concepts of 'cross­ cultural influence'. These studies focus on how certain Korean appropriations of 'otherness' of the 'exotic Western' imports within specific historical contexts have played an integral role in the ongoing process of conceptualizing and formulating forms of national and cultural identity.

Deformation behaviour of body centered cubic iron nanopillars containing coherent twin boundaries

Year: 2016
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Molecular dynamics simulations were performed to understand the role of twin boundaries on deformation behaviour of body-centred cubic (BCC) iron (Fe) nanopillars. The twin boundaries varying from one to five providing twin boundary spacing in the range 8.5 - 2.8 nm were introduced perpendicular to the loading direction. The simulation results indicated that the twin boundaries in BCC Fe play a contrasting role during deformation under tensile and compressive loadings. During tensile deformation, a large reduction in yield stress was observed in twinned nanopillars compared to perfect nanopillar. However, the yield stress exhibited only marginal variation with respect to twin boundary spacing. On the contrary, a decrease in yield stress with increase in twin boundary spacing was obtained during compressive deformation. This contrasting behaviour originates from difference in operating mechanisms during yielding and subsequent plastic deformation. It has been observed that the deformation under tensile loading was dominated mainly by twin growth mechanism, due to which the twin boundaries offers a negligible resistance to slip of twinning partials. This is reflected in the negligible variation of yield stress as a function of twin boundary spacing. On the other hand, the deformation was dominated by nucleation and slip of full dislocations under compressive loading. The twin boundaries offer a strong repulsive force on full dislocations resulting in the yield stress dependence on twin boundary spacing. Further, it has been observed that the curved twin boundary can acts as a source for full dislocation. The occurrence of twin-twin interaction during tensile deformation and dislocation-twin interaction during compressive deformation were presented and discussed.

description: We present the discovery of a new, peculiar form of double-periodic pulsation in RR Lyrae stars. In four, long-period ($P>0.6$ d) stars observed by the Optical Gravitational Lensing Experiment, and classified as fundamental mode pulsators (RRab), we detect additional, low-amplitude variability, with period shorter than fundamental mode period. The period ratios fall in a range similar to double-mode fundamental and first overtone RR Lyrae stars (RRd), with the exception of one star, in which the period ratio is significantly lower and nearly exactly equals 0.7. Although period ratios are fairly different for the four stars, the light curve shapes corresponding to the dominant, fundamental mode are very similar. The peak-to-peak amplitudes and amplitude ratios (Fourier parameters $R_{21}$ and $R_{31}$) are among the highest observed in RRab stars of similar period, while Fourier phases ($φ_{21}$ and $φ_{31}$) are among the lowest observed in RRab stars. If the additional variability is interpreted as due to radial first overtone, then, the four stars are the most extreme RRd variables of the longest pulsation periods known. Indeed, the observed period ratios can be well modelled with high metallicity pulsation models. However, at such long pulsation periods, first overtone is typically damped. Five other candidates, with weak signature of additional variability, sharing the same characteristics, were also detected and are briefly discussed.

description: One‐pot chemical vapor deposition (CVD) growth of large‐area Janus SeMoS monolayers is reported, with the asymmetric top (Se) and bottom (S) chalcogen atomic planes with respect to the central transition metal (Mo) atoms. The formation of these 2D semiconductor monolayers takes place upon the thermodynamic‐equilibrium‐driven exchange of the bottom Se atoms of the initially grown MoSe₂ single crystals on gold foils with S atoms. The growth process is characterized by complementary experimental techniques including Raman and X‐ray photoelectron spectroscopy, transmission electron microscopy, and the growth mechanisms are rationalized by first principle calculations. The remarkably high optical quality of the synthesized Janus monolayers is demonstrated by optical and magneto‐optical measurements which reveal the strong exciton–phonon coupling and enable an exciton g‐factor of −3.3.

description: Recent work suggests that galaxy evolution, and the build-up of stellar mass (M*) over cosmic time, is characterized by changes with redshift of star formation rate (SFR) and oxygen abundance (O/H). In a companion paper, we have compiled a large dataset to study Metallicity Evolution and Galaxy Assembly (MEGA), consisting of roughly 1000 galaxies to z=3.7 with a common O/H calibration. Here we interpret the MEGA scaling relations of M*, SFR, and O/H with an updated version of the model presented by Dayal et al. (2013). This model successfully reproduces the observed O/H ratio of 80,000 galaxies selected from the Sloan Digital Sky Survey to within 0.05-0.06 dex. By extending the model to the higher redshift MEGA sample, we find that although the specific mass loading of outflows does not change measurably during the evolution, the accretion rate and gas content of galaxies increase significantly with redshift. These two effects can explain, either separately or possibly in tandem, the observed lower metal abundance of high-z galaxies.

Constraining the geometry of PSR J0855-4644: A nearby Pulsar Wind Nebula with Double Torus/Jet Morphology

description: Aims: PSR J0855-4644 is a fast-spinning, energetic pulsar discovered at radio wavelengths near the south-eastern rim of the supernova remnant RX J0852.0-4622. A follow-up observation revealed the pulsar's X-ray counterpart and a slightly asymmetric PWN suggesting possible jet structures. PSR J0855-4644 is a pulsar with one of the highest \dot{E}/d^{2} from which no GeV γ-ray pulsations have been detected. Methods: With a dedicated Chandra observation, we perform detailed spatial modelling to constrain the geometry of the PWN, in particular the pulsar's line of sight ζ_{\rm PSR}. We also perform geometric radio and γ-ray light curve modelling to further constrain ζ_{\rm PSR} and the magnetic obliquity α. Results: The observation reveals that the compact XMM source, thought to be the X-ray pulsar, can be further resolved into a point source surrounded by an elongated axisymmetric nebula with a longitudinal extent of 10". The pulsar flux represents only \sim 1\% of the XMM compact source and its spectrum is well described by a blackbody of temperature kT=0.2 keV while the surrounding nebula has a much harder spectrum (Γ=1.1 for a power-law model). Assuming the origin of the extended emission is from a double torus yields ζ_{\rm PSR}=32.5\dg \pm 4.3\dg. Independent constraints from geometric light curve modelling yield α\lesssim55\dg and ζ\lesssim55\dg, and 10\dg\lesssim|ζ-α|\lesssim30\dg. A χ^2 fit to the radio light curve yields a best fit at (α,ζ_{\rm PSR}) = (22\dg, 8\dg), with an alternative fit at (α,ζ_{\rm PSR}) = (9\dg, 25\dg) within 3σ. Such a geometry would explain, in the standard caustic pulsar model picture, the radio-loud and γ-ray-quiet behaviour of this high \dot{E}/d^{2} pulsar.

description: Bei der Problemlösung müssen Konstrukteure die Ursachen von Fehlern und unerwünschtem Systemverhalten auf die Gestalt von Bauteilen zurückführen. Erst dieses Wissen ermöglicht eine zielgerichtete Entwicklung. Untersuchungen in anderen Disziplinen legen nahe, dass die Informationsaufnahme und -verarbeitung bei der Fehleranalyse durch systematische Denkfehler wie den Confirmation Bias beeinflusst wird. Der Confirmation Bias führt dazu, dass Informationen so gesucht und interpretiert werden, dass sie die eigenen Ansichten bestätigen. Bisher ist der Einfluss dieser Denkfehler auf die Fehleranalyse von Konstrukteuren jedoch noch nicht erforscht. Bekannte Methoden der Fehleranalyse adressieren nicht die Aspekte, die zur Reduktion des Confirmation Bias empfohlen werden. Zur Untersuchung des Confirmation Bias wurde Konstrukteuren und Studierenden ein Fehlerfall aus der Industrie vorgelegt. Die Teilnehmer sollten die Fehlerursache identifizieren und eine konstruktive Lösung entwickeln. Mit Eye-Tracking und Think-Aloud wurde der Einfluss des Confirmation Bias auf die Informationssuche und -interpretation analysiert. Es konnte nachgewiesen werden, dass sowohl irrelevante als auch widerlegende Informationen fehlinterpretiert wurden, um eigene Annahmen zu bestätigen. Ein Einfluss des Confirmation Bias auf die visuelle Informationssuche konnte nicht beobachtet werden. Jedoch wurden relevante Indizien nur kurz betrachtet. Die geringere visuelle Aufmerksamkeit ist daher eine mögliche Ursache für Fehlinterpretationen. Die Erkenntnisse der ersten deskriptiven Studie wurden genutzt, um die Methode Design-ACH zu entwickeln, mit der der Confirmation Bias bei der Fehleranalyse reduziert werden soll. Bei der Anwendung der Design-ACH werden mehrere Hypothesen zur Fehlerursache aufgestellt und vorliegenden Indizien gegenübergestellt. Durch Falsifikation der Hypothesen wird dann die wahrscheinlichste Hypothese ausgewählt. Die Design-ACH unterstützt zudem die Definition weiterer Untersuchungen, wenn auf Basis der vorliegenden Informationen keine Hypothese ausgewählt werden kann. Die Design-ACH wurde sowohl in einer Labor- als auch einer Feldevaluation analysiert. Die Laborevaluation zeigt, dass die Design-ACH den Confirmation Bias bei der Fehleranalyse reduzieren kann. In der Fallstudie wurde die Design-ACH mit Konstrukteuren an einer realen Problemstellung aus deren Unternehmen angewendet. Die Fallstudie zur Methodenevaluation zeigte zudem, dass die Design-ACH auch bei realen Unternehmensproblemen die Fehleranalyse unterstützt.

description: γ‐Glutamylamine synthetases are an important class of enzymes that play a key role in glutamate‐based metabolism. Methionine sulfoximine (MSO) is a well‐established inhibitor for the archetypal glutamine synthetase (GS) but inhibitors for most GS‐like enzymes are unknown. Assuming a conserved catalytic mechanism for GS and GS‐like enzymes, we explored if subtype‐selective inhibitors can be obtained by merging MSO with the cognate substrates of the respective GS‐like enzymes. Using GlnA4Sc from Streptomyces coelicolor, an enzyme recently shown to produce γ‐glutamylethanolamine, we demonstrate that MSO can be reengineered in a straightforward fashion into potent and selective GlnA4Sc inhibitors. Linkage chemistry as well as linker length between the MSO moiety and the terminal hydroxyl group derived from ethanolamine were in agreement with the postulated phosphorylated catalytic intermediate. The best GlnA4 inhibitor 7 b potently blocked S. coelicolor growth in the presence of ethanolamine as the sole nitrogen source. Our results provide the first GlnA4Sc‐specific inhibitors and suggest a general strategy to develop mechanism‐based inhibitors for GS‐like enzymes.

description: This paper is devoted to investigate the pattern formation of a volume-filling chemotaxis model with logistic cell growth. We first apply the local stability analysis to establish sufficient conditions of destabilization for uniform steady-state solution. Then, weakly nonlinear analysis with multi-scales is used to deal with the emerging process of patterns near the bifurcation point. For the single unstable mode case, we derive the Stuart-Landau equations describing the evolution of the amplitude, and thus the asymptotic expressions of patterns are obtained in both supercritical case and subcritical case. While for the case of multiple unstable modes, we also derive coupled amplitude equations to study the competitive behavior between two unstable modes through the phase plane analysis. In particular, we find that the initial data play a dominant role in the competition. All the theoretical and numerical results are in excellently qualitative agreement and better quantitative agreement than that in [1]. Moreover, in the subcritical case, we confirm the existence of stationary patterns with larger amplitudes when the bifurcation parameter is less than the first bifurcation point, which gives an positive answer to the open problem proposed in [2].

description: The main goal of this work is to design constellations in a system of Physical-layer Network Coding (PNC). The design is based on constellations over two commutative rings: GAUSSIAN Integers and EISENSTEIN Integers. Using this particular system as a working base, first we have identified the needed theory in the design, as well as the needed performance metrics in order to analyse the proposed constellations. Then, we have presented the most used constellations nowadays in order to be used as a comparison. Finally, we have proposed a design methodology and four newly derived proposals. Further, the obtained results have been analysed and the particular studied PNC system has been implemented.

description: This article reviews low-temperature heat transport studies of spin-gapped quantum magnets in the last few decades. Quantum magnets with small spins and low dimensionality exhibit a variety of novel phenomena. Among them, some systems are char-acteristic of having quantum-mechanism spin gap in their magnetic excitation spectra, including spin-Peierls systems, S = 1 Haldane chains, S = 1/2 spin ladders, and spin dimmers. In some particular spin-gapped systems, the XY-type antiferromagnetic state induced by magnetic field that closes the spin gap can be described as a magnon Bose-Einstein condensation (BEC). Heat transport is effective in probing the magnetic excitations and magnetic phase transitions, and has been extensively studied for the spin-gapped systems. A large and ballistic spin thermal conductivity was observed in the two-leg Heisenberg S = 1/2 ladder compounds. The characteristic of magnetic thermal transport of the Haldane chain systems is quite controversial on both the theoretical and experimental results. For the spin-Peierls system, the spin excitations can also act as heat carriers. In spin-dimer compounds, the magnetic excitations mainly play a role of scattering phonons. The magnetic excitations in the magnon BEC systems displayed dual roles, carrying heat or scattering phonons, in different materials.

description: In this paper we present a combined photometric, spectroscopic and orbital period study of three early-type eclipsing binary systems: XZ Aql, UX Her, and AT Peg. As a result, we have derived the absolute parameters of their components and, on that basis, we discuss their evolutionary states. Furthermore, we compare their parameters with those of other binary systems and with the theoretical models. An analysis of all available up-to-date times of minima indicated that all three systems studied here show cyclic orbital changes, their origin is discussed in detail. Finally, we performed a frequency analysis for possible pulsational behavior and as a result we suggest that XZ Aql hosts a δ Scuti component.

description: Η παρούσα ερευνητική εργασία πραγματεύεται την σημασία που έχει η προβολή του σύνθετου κοινωνικού ρόλου του πανεπιστημίου με την παρουσία του στην πόλη. Επιπλέον, γίνεται διερεύνηση για τις παραμέτρους που καθορίζουν τον χαρακτήρα της πανεπιστημιακής δομής και κατά επέκταση το πως αυτή επηρεάζει και διαμορφώνει τη σχέση που αναπτύσσει με τον αστικό ιστό.
Κατά πόσο λοιπόν η χωροθέτηση, ο τύπος και η μορφή οργάνωσης ως παράμετροι επηρεάζουν τον χαρακτήρα του πανεπιστημίου και αντιστρόφως τι ρόλο έχουν στην ανάπτυξη της σχέσης πανεπιστημίου με την πόλη;
Αναλυτικότερα, εξετάζονται οι παράμετροι της χωροθέτησης, της τυπολογίας και της μορφής μέσω της ιστορικής εξέλιξης των πανεπιστημίων στον διεθνή και στον ελλαδικό χώρο. Η ανάλυση των παραπάνω  παραμέτρων γίνεται με την παράθεση παραδειγμάτων χρονολογικά όπου παράλληλα σημειώνονται και τα χωρικά μοντέλα οργάνωσης των πανεπιστημίων καθώς και αυτά που επηρεάζονται από τις παραμέτρους που θέσαμε. Πιο συγκεκριμένα, στο τέλος μελετάται η περίπτωση της Λεμεσού με το Τεχνολογικό Πανεπιστήμιο Κύπρου ως προς το χωρικό μοντέλο οργάνωσης των πανεπιστημιακών του εγκαταστάσεων (μοντέλο διάχυτης αστικής χωροθέτησης των πανεπιστημιακών εγκαταστάσεων) και τι είδους αλληλεπιδράσεις αναπτύσσονται με την πανεπιστημιακή κοινότητα και την πόλη.

description: ATAs engineered for having an enlarged small binding pocket were applied for the synthesis of enantiomerically pure (R)‐benzo[1,3]dioxol‐5‐yl‐butylamine, a chiral component of human leukocyte elastase inhibitor DMP 777 (L‐694,458). Kinetic resolution of the racemic amine was performed by using the L59A variant of the (S)‐selective ATA from Chromobacterium violaceum (Cv‐ATA), providing the residual (R)‐enantiomer in excellent yield and >99% ee. At moderate enzyme loading and absence of co‐solvent, high volumetric productivity of 0.22 mol L⁻¹ h⁻¹ (42.5 g L⁻¹ h⁻¹) was achieved. Complementarily, the (S)‐enantiomer was generated via kinetic resolution using the (R)‐selective ATA‐117‐Rd11 from Arthrobacter sp. with acetone as the amino acceptor. In an alternative approach, we employed ATA‐117‐Rd11 for the asymmetric amination of the prochiral ketone precursor, which at 86% conversion gave the (R)‐benzo[1,3]dioxol‐5‐yl‐butylamine with excellent >99% ee. We further evaluated the utility of Cv‐ATA L59A for the asymmetric synthesis of pharmaceutically relevant (S)‐1‐phenylbutan‐1‐amine, a chiral component of the deubiquitinase inhibitor degrasyn (WP1130). The enzyme showed good tolerance to high concentrations of isopropylamine, producing (S)‐1‐phenylbutan‐1‐amine in enantiomerically pure form (>99% ee).

description: Below $T_N = 1.1$K, the XY pyrochlore Er$_2$Ti$_2$O$_7$ orders into a $k=0$ non-collinear, antiferromagnetic structure referred to as the $ψ_2$ state. The magnetic order in Er$_2$Ti$_2$O$_7$ is known to obey conventional three dimensional (3D) percolation in the presence of magnetic dilution, and in that sense is robust to disorder. Recently, however, two theoretical studies have predicted that the $ψ_2$ structure should be unstable to the formation of a related $ψ_3$ magnetic structure in the presence of magnetic vacancies. To investigate these theories, we have carried out systematic elastic and inelastic neutron scattering studies of three single crystals of Er$_{2-x}$Y$_x$Ti$_2$O$_7$ with $x=0$ (pure), 0.2 (10$\%$-Y) and 0.4 (20$\%$-Y), where magnetic Er$^{3+}$ is substituted by non-magnetic Y$^{3+}$. We find that the $ψ_2$ ground state of pure Er$_2$Ti$_2$O$_7$ is significantly affected by magnetic dilution. The characteristic domain selection associated with the $ψ_2$ state, and the corresponding energy gap separating $ψ_2$ from $ψ_3$, vanish for Y$^{3+}$ substitutions between 10$\%$-Y and 20$\%$-Y, far removed from the 3D percolation threshold of $\sim$60$\%$-Y. The resulting ground state for Er$_2$Ti$_2$O$_7$ with magnetic dilutions from 20$\%$-Y up to the percolation threshold is naturally interpreted as a frozen mosaic of $ψ_2$ and $ψ_3$ domains.

description: We study phase equilibria in a minimal model of charge-regulated polymer solutions. Our model consists of a single polymer species whose charge state arises from protonation-deproto- nation processes in the presence of a dissolved acid, whose anions serve as screening counteri- ons. We explicitly account for variability in the polymers' charge states. Homogeneous equilibria in this model system are characterised by the total concentration of polymers, the concentration of counter-ions and the charge distributions of polymers which can be computed with the help of analytical approximations. We use these analytical results to characterise how parameter values and solution acidity influence equilibrium charge distributions and identify for which regimes uni- modal and multi-modal charge distributions arise. We then study the interplay between charge regulation, solution acidity and phase separation. We find that charge regulation has a significant impact on polymer solubility and allows for non-linear responses to the solution acidity: re-entrant phase behaviour is possible in response to increasing solution acidity. Moreover, we show that phase separation can yield to the coexistence of local environments characterised by different charge distributions and mixture com

description: Despite the rise of digital photography, physical photos remain significant. They support social practices for maintaining social bonds, particularly in family contexts as their handling can trigger emotions associated with the individuals and themes depicted. Also, digital media can be used to strengthen the meaning of physical objects and environments represented in the material world through augmented reality, where such are overlaid with additional digital information that provide supplementary sensory context to topics conveyed. This poster therefore presents initial findings from the development of augmented photobooks to create ‘a-photobooks’, printed photobooks that are augmented by travellers with additional multimedia of their trip using a smartphone-based authoring tool. Results suggest a-photobooks could support more immersive engagement and reminiscing of holidays encounters, increasing cognitive, and emotional effects of associated experiences.

description: The stochastic addition of either vertices or connections in a network leads to the observation of the percolation transition, a structural change with the appearance of a connected component encompassing a finite fraction of the system. Percolation has always been regarded as a substrate-dependent but model-independent process, in the sense that the critical exponents of the transition are determined by the geometry of the system, but they are identical for the bond and site percolation models. Here, we report a violation of such assumption. We provide analytical and numerical evidence of a difference in the values of the critical exponents between the bond and site percolation models in networks with null percolation thresholds, such as scale-free graphs with diverging second moment of the degree distribution. We discuss possible implications of our results in real networks, and provide additional insights on the anomalous nature of the percolation transition with null threshold.
