title: Aspects of the manufacture, trade and history of smalt
Creators: name: Tyler, Matthew James

Subjects: subject: Smalt, pigments, cobalt, zaffre, Saxony, manufacturing, recipes, technical art history, Rembrandt, blue, glassmaking.

description: Smalt is a potassium-fluxed, cobalt blue-coloured glass powder that became popular throughout Europe from the late 15th to the mid-19th century as a pigment for oil painting. Current literature has dealt with the history and manufacture of smalt in a manner that is not comprehensive. The PhD originated in the quantitative studies carried out on paintings in the National Gallery collection; the objective was to take the study of the historical sources and literature further, interpreting the new information through the lens of the quantitative trends and analyses and raising new questions in the process. The thesis uses a cross-disciplinary methodological approach to address these areas, built from a combination of comparative analysis of the familiar documentary sources, and experiment design to reconstruct and measure the colour and powder characteristics of the pigment. A study of 17th-19th century manufacturing sources, and 15th-16th century glassmaking manuscripts and books of secrets, uncovered detail about the impurities found in smalt pigment from the industrial manufacturing process and revealed connections between the origin of smalt and the history of enamelling. These outcomes were confirmed through examination of objects in the Rijksmuseum collection, and led further to an experiment to reconstruct the pigment, to explore the main characteristics of its colour. The results of this experiment led to a deeper understanding of the influence of cobalt, nickel, and iron oxides and their relationship to the particle size distribution of smalt as a powder. Finally, the image analysis tools used for particle size measurement were adapted into a new methodology for measuring smalt in cross-sections of paintings. The particle size measurement method was combined with compositional data from SEM-EDX, and closeups of paintings, to examine the colour and use of smalt by Paolo Veronese (1528-88) and Rembrandt van Rijn (1606-1669). Conclusions involved an assessment of what smalts these artists would have used and how they would looked before being mixed with a binding medium.

description: T-cell receptors (TCR) are key proteins of the adaptive immune system, generated randomly in each individual, whose diversity underlies our ability to recognize infections and malignancies. Modeling the distribution of TCR sequences is of key importance for immunology and medical applications. Here, we compare two inference methods trained on high-throughput sequencing data: a knowledge-guided approach, which accounts for the details of sequence generation, supplemented by a physics-inspired model of selection; and a knowledge-free Variational Auto-Encoder based on deep artificial neural networks. We show that the knowledge-guided model outperforms the deep network approach at predicting TCR probabilities, while being more interpretable, at a lower computational cost.

description: We present a concise formula to relate the effective mass term of the neutrinoless double beta decay to a single neutrino mass, two Majorana CP-violating phases and four observables of neutrino oscillations for a generic neutrino mass spectrum. If the alleged evidence for the neutrinoless double beta decay is taken into account, one may obtain a rough but model-independent constraint on the absolute scale of neutrino masses -- it is most likely to be in the range between 0.1 eV and 1 eV.

description: Machine learning algorithms have recently emerged as a tool to generate force fields which display accuracies approaching the ones of the ab-initio calculations they are trained on, but are much faster to compute. The enhanced computational speed of machine learning force fields results key for modelling metallic nanoparticles, as their fluxionality and multi-funneled energy landscape needs to be sampled over long time scales. In this review, we first formally introduce the most commonly used machine learning algorithms for force field generation, briefly outlining their structure and properties. We then address the core issue of training database selection, reporting methodologies both already used and yet unused in literature. We finally report and discuss the recent literature regarding machine learning force fields to sample the energy landscape and study the catalytic activity of metallic nanoparticles.

Going Forward by Looking Backwards on the Environmental Kuznets Curve: an Analysis of CFCs, CO2 and the Montreal and Kyoto Protocols

Subjects: subject: Environmental Economics and Policy

subject: Kyoto Protocol

description: The success of the Montreal Protocol in comparison to the stagnation seen in negotiations surrounding the Kyoto Protocol highlights the importance of: i) a supportive industry group, ii) pre-existing legislation and commitment by a lead nation, iii) affordable and available substitutes and iv) acceptance of the underlying scientific explanation of the link between emissions and a key detrimental impact. The focus on these contrasting intergovernmental agreements is driven, in part, by the intention to establish that successful emission reductions tend to be associated with a concerted policy effort. This is in contrast to the concept of the Environmental Kuznets Curve (EKC) which contends that a significant negative relationship exists between high levels of national income and per capita emissions. While a nation’s level of development and national income are likely to be linked to an ability to make structural changes and/or the implement environmental policy, this paper finds no evidence of an EKC consistent negative quadratic relationship between income and CFC emissions once key considerations, such as biased estimations and policy effort, have been accounted for.

description: In the context of the recent debate on the objectives, measures and funding of a post-2013 CAP, there is growing consensus that one of the rationales of a future policy will be to support the provision of public goods. As a contribution to this debate, the paper draws on several case study examples to illustrate where the territorial approach has been effective in supporting both the provision of environmental public goods and the generation of direct and second order social and economic effects. These include opportunities for rural tourism,recreation and the development of local markets, which over time, have generated further opportunities for public and private investments. In one example in which these positive linkages are very much in evidence, the territorial approach has been operationalised through the Italian LAG Delta 2000, and reinforced through subsequently securing a range of additional financial resources (regional incentives, ESF within EQUAL, cooperation programmes, EU youth programme and Cultura 2000).

description: The position of a field-tuned superconductor-insulator quantum transition occuring in disordered thin films is examined within the mean field approximation. Our calculation shows that the microscopic disorder-induced reduction of the quantum transition point found experimentally cannot be explained if the interplay between the disorder and an electron-electron repulsive interaction is ignored. This work is presented as a microscopic basis of an explanation (cond-mat/0105122) of resistive phenomena near the transition field.

Subjects: subject: lean production, implementation, regional context, regional dimensions, lean practices, lean design, aerospace, culture.

description: Lean production has been widely implemented with the aim of improving performance. However, despite its popularity, there is still a gap in the literature when considering the impact of regional dimension. Although there have been a small number of studies in this area, they have lacked in-depth analysis. Therefore, this study aims to investigate in detail the regional dimensions that impact upon lean implementation. Lean production implementation will be viewed through two lenses: (i) as a set of practices and (ii) production systems design. Four regional dimensions were examined: cultural, geographical, financial and legal. Cases within the aerospace industry, across Europe (the region), provided the backdrop to this study. Data was collected via semi-structured interviews with managers and examined and analysed using a thematic analysis methodology to investigate the phenomena in detail. The findings revealed that regional dimensions do have an impact, with cultural and geographical dimensions being more significant than the others. The cultural dimension within the company and country showed a variety of aspects that have an impact on lean production implementation. Moreover, from a regional perspective, the data showed that the location of suppliers plays a significant role in the implementation of lean practices. The financial and legal dimensions uncovered budget decisions and regulations that restricted the implementation of lean processes. The study and findings also provide new insights into the literature, through a more comprehensive review on contingencies impacting successful lean production implementation. In addition, the findings will better prepare practitioners to manage the level of cost-efficiency and negative effects of lean production adoption/implementation.

Nieh-Yan Anomaly: Torsional Landau Levels, central charge and anomalous thermal Hall effect

description: The Nieh-Yan anomaly is the anomalous breakdown of the chiral U(1) symmetry caused by the interaction between torsion and fermions. We study this anomaly from the point of view of torsional Landau levels. It was found that the torsional Landau levels are gapless, while their contributions to the chiral anomaly are canceled, except those from the lowest torsional Landau levels. Hence, the dimension is effectively reduced from (3+1)-dimensional to (1+1)-dimensional. We further show that the coefficient of the Nieh-Yan anomaly is the free energy density in (1+1) dimensions. Especially, at finite temperature, the thermal Nieh-Yan anomaly is proportional to the central charge. The anomalous thermal Hall conductance in Weyl semimetals is then shown to be proportional to the central charge, which is the experimental fingerprint of the thermal Nieh-Yan anomaly.

description: We find a uniform semiclassical (SC) wave function describing coherent branched flow through a two-dimensional electron gas (2DEG), a phenomenon recently discovered by direct imaging of the current using scanned probed microscopy. The formation of branches has been explained by classical arguments, but the SC simulations necessary to account for the coherence are made difficult by the proliferation of catastrophes in the phase space. In this paper, expansion in terms of "replacement manifolds" is used to find a uniform SC wave function for a cusp singularity. The method is then generalized and applied to calculate uniform wave functions for a quantum-map model of coherent flow through a 2DEG. Finally, the quantum-map approximation is dropped and the method is shown to work for a continuous-time model as well.

description: The ground states of bosons have been classified into superfluid, Mott insulator, and bose glass. Recent experiments in two-dimensional superconductors strongly suggest the existence of the fourth quantum state of Cooper pairs, i.e., bose metal or quantum metal, where the resistivity remains constant at lowest temperature. However, its theoretical understanding remains unsettled. In this paper, we show theoretically that the bosons in the dilute limit subject to dissipation can lose the superfluidity and remain metallic, utilizing the Feynman's picture of superfluidity in the first quantized formulation. This result is relevant to the quantum vortices under an external magnetic field in two-dimensional superconductors with the finite resistivity of the normal core as the source of dissipation.

description: Os debates hodiernos sobre a violência que se abate mais sobre as mulheres, revelam quanto as questões de género na família e fora dela podem criar dissensões, dilemas e confusões. Embora o aumento da violência sobre os homens também tenha vindo a subir, muitas vezes, é menos por réplica do que por estratégia de defesa das mulheres. Seja qual for a sua índole, a violência está associada às desigualdades estruturais no seio das sociedades e ao abuso do poder, confortados pelas estruturas sociais que encorajam as desigualdades de género. Assim, as atitudes e os comportamentos dos homens mas também de algumas mulheres são pelo menos paradoxais e continuam a testar as fronteiras que se abatem entre eles em termos de igualdade, de respeito pela dignidade de cada um. Neste trabalho, numa perspetiva pluridisciplinar, de índole teórico-empírica, apoiando-nos sobretudo em dados retirados das entrevistas feitas junto de mulheres de condições e idades diversificadas, no concelho de Braga, procuramos relevar os mecanismos, os enredos e as contradições do fenómeno da violência doméstica no seio da família e da conjugalidade.

description: The periodic $OSp(1|2)$ quantum spin chain has both a graded and a non-graded version. Naively, the Bethe ansatz solution for the non-graded version does not account for the complete spectrum of the transfer matrix, and we propose a simple mechanism for achieving completeness. In contrast, for the graded version, this issue does not arise. We also clarify the symmetries of both versions of the model, and we show how these symmetries are manifested in the degeneracies and multiplicities of the transfer-matrix spectrum. While the graded version has $OSp(1|2)$ symmetry, the non-graded version has only $SU(2)$ symmetry. Moreover, we obtain conditions for selecting the physical singular solutions of the Bethe equations. This analysis solves a lasting controversy over signs in the Bethe equations.

description: It has been pointed out that matter bounce cosmology driven by a k-essence field cannot satisfy simultaneously the observational bounds on the tensor-to-scalar ratio and non-Gaussianity of the curvature perturbation. In this paper, we show that this is not the case in more general scalar-tensor theories. To do so, we evaluate the power spectra and the bispectra of scalar and tensor perturbations on a general contracting background in the Horndeski theory. We then discuss how one can discriminate contracting models from inflation based on non-Gaussian signatures of tensor perturbations.

Level-to-level fluctuations of the effective $g$-factor for Zeeman splitting are characterized, and the statistics are found to be well-described by random matrix theory predictions. The strength of spin-orbit scattering increases with atomic number and also varies between nanoparticles made of the same metal. The spin-orbit scattering rates in the nanoparticles are in order-of-magnitude agreement with bulk measurements on disordered samples.

Marcada pela convergência de tradições diversas, por vezes até antagónicas, a génese duma tal corrente está indubitavelmente associada, entre outras, à reflexão em torno das lutas ideológicas subjacentes às práticas culturais populares e à dicotomia texto/ leitor. Num segundo momento, afastando-nos da reflexão de cariz anglo-americano, centrar-nos-emos quase exclusivamente na evolução da corrente sociológica francesa dos estudos da comunicação, focalizando-nos em duas questões: a (i)legitimidade dos públicos mediáticos e a importância dos contextos de interacção.

title: Mathematical modelling of cancer invasion and metastatic spread
Creators: name: Franssen, Linnea Christin
Publisher: name: University of St Andrews
Year: 2019

description: Metastatic spread—the dissemination of cancer cells from a primary tumour with subsequent re-colonisation at secondary sites in the body—causes around 90% of cancer-related deaths. Mathematical modelling may provide a complementary approach to help understand the complex mechanisms underlying metastasis. In particular, the spatiotemporal evolution of individual cancer cells during the so-called invasion-metastasis cascade—i.e. during cancer cell invasion, intravasation, vascular travel, extravasation and metastatic growth—is an aspect not yet explored through existing mathematical models. In this thesis, such a spatially explicit hybrid multi-organ metastasis modelling framework is developed. It describes the invasive growth dynamics of individual cancer cells both at a primary site and at potential secondary metastatic sites in the body, as well as their transport from the primary to the secondary sites. Throughout, the interactions between the cancer cells, matrix-degrading enzymes (MDEs) and the extracellular matrix (ECM) are accounted for. Furthermore, the individual-based framework models phenotypic variation by distinguishing between cancer cells of an epithelial-like, a mesenchymal-like and a mixed phenotype. It also describes permanent and transient mutations between these cell phenotypes in the form of epithelial-mesenchymal transition (EMT) and its reverse process mesenchymal-epithelial transition (MET). Both of these mechanisms are implemented at the biologically appropriate locations of the invasion-metastasis cascade. Finally, cancer cell dormancy and death at the metastatic sites are considered to model the frequently observed maladaptation of metastasised cancer cells to their new microenvironments. To investigate the EMT-process further, an additional three-dimensional discrete-continuum model of EMT- and MET-dependent cancer cell invasion is developed. It consists of a hybrid system of partial and stochastic differential equations that describe the evolution of epithelial-like and mesenchymal-like cancer cells, again under the consideration of MDE concentrations and the ECM density. Using inverse parameter estimation and sensitivity analysis, this model is calibrated to an in vitro organotypic assay experiment that examines the invasion of HSC-3 cancer cells.

description: We suggest a way to disentangle self- from cross-correlation contributions in the dielectric spectra of glycerol. Recently it was demonstrated for monohydroxy alcohols that a detailed comparison of the dynamic susceptibilities of photon correlation and broadband dielectric spectroscopy allows to unambiguously disentangle a collective relaxation mode known as the Debye process, which could arises due to supramolecular structures, and the $α$-relaxation, which proves to be identical in both methods. In the present paper, we apply the same idea and analysis to the paradigmatic glass former glycerol. For that purpose we present new light scattering data from photon correlation spectroscopy measurements and combine these with literature data to obtain a data set covering a dynamic range from $10^{-4}-10^{13}\,$Hz. Then we apply the above mentioned analysis by comparing this data set with a corresponding set of broadband dielectric data. Our finding is that even in a polyalcohol self- and cross-correlation contributions can approximately be disentangled in that way and that the emerging picture is very similar to that in monohydroxy alcohols. This is further supported by comparing the data with fast field cycling NMR measurements and dynamic shear relaxation data from the literature, and it turns out that, within the described approach, the $α$-process appears very similar in all methods, while the pronounced differences observed in the spectral density are due to a different expression of the slow collective relaxational contribution. In the dielectric spectra the strength of this peak is reasonably well estimated by the Kirkwood correlation factor, which supports the view that it arises due to dynamic cross-correlations, which were previously often assumed to be negligible in dielectric measurements.

description: O termo delinquência juvenil, referido num contexto de complexas sequelas sociais, reporta-se aos comportamentos ou conjunturas ponderadas como violação normativa ou de transgressão, da população juvenil. A dinâmica e a soberania dos laços sociais potenciam a integração e a acção dos controlos internos e externos. Este estudo de caso tem como protagonista um recluso do sexo masculino, com 22 anos de idade, que se desenvolveu e se incrementou num trilho de delinquência. Quisemos perceber o seu percurso desenvolvimental, o que esteve na origem deste desfecho, no sentido de evitar ou minimizar consequências severas na vida de outras crianças que crescem em condições de adversidade. Não foi nossa intenção encontrar explicações ou conclusões generalistas, embora se pressupõe relações de causa-efeito. Utilizamos como instrumentos de avaliação a técnica da entrevista, e o questionário adaptado do modelo Youth Self-Report (YSR), Questionário de Autoavaliação para Jovens (Achenbach, 1991; versão portuguesa de Fonseca et al, 1999). Concluímos que todo o percurso de vida deste delinquente, se incrementou associado ao risco, à ausência ou limitação de experiências e falta de estimulação durante os primeiros anos de vida (i.e., o vínculo com a mãe, estrutura familiar), podendo ter desenvolvido défices cognitivos, sociais e adaptativos.

description: We consider a prototypical model in which a nonlinear field (continuum or discrete) evolves on a flexible substrate which feeds back to the evolution of the main field. We identify the underlying physics and potential applications of such a model and examine its simplest one-dimensional Hamiltonian form, which turns out to be a modified Frenkel-Kontorova model coupled to an extra linear equation. We find static kink solutions and study their stability, and then examine moving kinks (the continuum limit of the model is studied too). We observe how the substrate effectively renormalizes properties of the kinks. In particular, a nontrivial finding is that branches of stable and unstable kink solutions may be extended beyond a critical point at which an effective intersite coupling vanishes; passing this critical point does not destabilize the kink. Kink-antikink collisions are also studied, demonstrating alternation between merger and transmission cases.

description: We analyse the relation between anomalies in their manifestly supersymmetric formulation in superspace and their formulation in Wess-Zumino (WZ) gauges. We show that there is a one-to-one correspondence between the solutions of the cohomology problem in the two formulations and that they are related by a particular choice of a superspace counterterm ("scheme"). Any apparent violation of $Q$-supersymmetry is due to an explicit violation by the counterterm which defines the scheme equivalent to the WZ gauge. It is therefore removable.

description: Since its invention in 1999, optical centrifuge has become a powerful tool for controlling molecular rotation and studying molecular dynamics and molecular properties at extreme levels of rotational excitation. The technique has been applied to a variety of molecular species, from simple linear molecules to symmetric and asymmetric tops, to molecular ions and chiral enantiomers. Properties of isolated ultrafast rotating molecules, so-called molecular superrotors, have been investigated, as well as their collisions with one another and interaction with external fields. The ability of an optical centrifuge to spin a particular molecule of interest depends on both the molecular structure and the parameters of the centrifuge laser pulse. An interplay between these two factors dictates the utility of an optical centrifuge in any specific application. Here, we discuss the strategy of assessing and adjusting the properties of the centrifuge to those of the molecular rotors, and describe two practical examples of optical centrifuges with very different characteristics, implemented experimentally in our laboratory.

Evolution of the Deterministic Collapse Barrier of the Field Clusters as a Probe of Cosmology

subject: FOS: Physical sciences

description: The collapse barrier, $δ_{c}$, of the field clusters located in the low-density environment is deterministic rather than diffusive, unlike that of the wall counterparts located in the superclusters. Analyzing the data from the Mira-Titan simulations for eleven different cosmologies including the standard $Λ$CDM cosmology at various redshifts, we investigate the evolution of the deterministic collapse barrier of the field clusters and explore its dependence on the background cosmology. Regardless of the background cosmology, the deterministic $δ_{c}$ exhibits a universal behavior of having a higher value than the Einstein-de Sitter spherical collapse barrier height of $δ_{sc}=1.686$, at $z=0$ but gradually converging down to $δ_{sc}$ as the dominance of dark energy diminishes with the increment of $z$. A significant difference among different cosmologies, however, is found in its convergence rate as well as in the critical redshift $z_{c}$ at which $δ_{c}=δ_{sc}$. Showing that the convergence rate and critical redshifts can distinguish even between the degenerate cosmologies which yield almost identical linear growth factor and cluster mass functions, we suggest that the evolution of the deterministic collapse barrier of the field clusters should be a powerful complementary probe of cosmology.

The PP2PP Experiment at RHIC
Creators: name: Chwastowski, J.
Publisher: name: arXiv
Year: 2002
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The PP2PP experiment is devoted to the proton-proton elastic scattering measurement at the Relativistic Heavy Ion Collider at the centre-of-mass energies between 50 and 500 GeV and the four-momentum transfer $0.0004 \leq |t| \leq 1.3$ Gev$^2$. The option of polarized proton beams offers a unique possibility to investigate the spin dependence of the proton elastic scattering in a systematic way. The energy dependence of the total and elastic cross section, the ratio of the real to the imaginary part of the forward scattering amplitude, and the nuclear slope parameter will be studied. In the medium $|t|$ region ($|t| \leq 1.3$ Gev$^2$) the energy dependence of the dip structure in the elastic differential cross section will be measured. With polarized beams the measurement of spin dependent observables: the difference of the total cross sections as function of the of initial transverse spin states, the analyzing power and the double spin asymmetries will be used to map the $s$ and $t$ dependence of the proton helicity amplitudes.

description: Frustrated spin-1/2 chains, despite the apparent simplicity, exhibit remarkably rich phase diagram comprising vector-chiral (VC), spin-density-wave (SDW) and multipolar/spin-nematic phases as a function of the magnetic field. Here we report a study of $β$-TeVO$_4$, an archetype of such compounds, based on magnetization and neutron diffraction measurements up to 25 T. We find the transition from the helical VC ground state to the SDW state at $\sim$3 T for the magnetic field along the $a$ and $c$ crystal axes, and at $\sim$9 T for the field along the $b$ axis. The high-field (HF) state, existing above $\sim$18 T, i.e., above $\sim$1/2 of the saturated magnetization, is an incommensurate magnetically ordered state and not the spin-nematic state, as theoretically predicted for the isotropic frustrated spin-1/2 chain. The HF state is likely driven by sizable interchain interactions and symmetric intrachain anisotropies uncovered in previous studies. Consequently, the potential existence of the spin nematic phase in $β$-TeVO$_4$ is limited to a narrow field range, i.e., a few tenths of a tesla bellow the saturation of the magnetization, as also found in other frustrated spin-1/2 chain compounds.

description: High resolution spin-resolved photoemission is used to probe the properties of a Gd(0001) surface state. The state shows both a spin-mixing behavior reflecting the exchange of magnons with the local moments and a reduction of the exchange splitting with increasing temperature. The surface state polarization at low T suggests that the surface layer has an enhanced Tc of 365K or greater. Measurements of the photoemission linewidths show that at low temperatures, the lifetime of a majority spin photohole is predominantly limited by electron-phonon scattering and that of a minority spin photohole by electron-magnon scattering. Since similar behavior may be expected for bulk states close to the Fermi level, the transport properties of this material will also be determined by different decay mechanisms in the two channels.
