description: Objects are there to be used. Throughout history, the gifting of objects has been a universal activity. Anthropologists, sociologists, economists, philosophers, and historians (amongst others) have all grappled to define the role that gift-giving has played in diverse human societies. The act of gifting immediately modifies the value of an object, transfiguring it into a ‘gift’. Once defined as a gift, both the object and its presentation contain particular meanings which resonate within the context of its exchange: the gift both communicates a message and a bond between sender and recipient. The resulting web of connections formed by gift exchanges are arguably the sinews of complex societies. The gift debits and credits, it obligates and liberates, it intimates and discriminates, not only between the one who gifts and the one who receives, but by those who view its exchange (who interpret the symbolism of a gift as indicative of a relationship or favour). In a society in which loyalty, gratitude, obligation, courtesy, personal conduct, and social standing matter acutely – for example, sixteenth-century Europe – the gift is a truly efficacious social tool. In the hands of someone who understands the communicative power of objects, particularly artworks, but not solely – for example, Cosimo I de’ Medici (1519-1574) – then gifts, both those given and received, can force the actions of others, influence the perception of the audience, and effect the realisation of political objectives. As such, the Florentine court – famous for its magnificent collections of objects – represents an outstanding historical context in which to analyse the efficacy of gifts and the social and political world of material culture they inhabit. This thesis draws upon a vast trove of unpublished archival material to study the potency of gifts in the diplomacy of Cosimo I de’ Medici, duke of Florence (from 1537), later Siena (from 1557), and finally, grand duke of Tuscany (from 1570). As well as portraying the social value of the gift in sixteenth-century Europe and tracing the influence of gifts and their presentation in the iconographic programme of the Palazzo Vecchio, this thesis also presents a diplomatic biography of Cosimo I through the gifts he sent and received.

description: In this paper, we present a deep autoencoder based energy method (DAEM) for the bending, vibration and buckling analysis of Kirchhoff plates. The DAEM exploits the higher order continuity of the DAEM and integrates a deep autoencoder and the minimum total potential principle in one framework yielding an unsupervised feature learning method. The DAEM is a specific type of feedforward deep neural network (DNN) and can also serve as function approximator. With robust feature extraction capacity, the DAEM can more efficiently identify patterns behind the whole energy system, such as the field variables, natural frequency and critical buckling load factor studied in this paper. The objective function is to minimize the total potential energy. The DAEM performs unsupervised learning based on random generated points inside the physical domain so that the total potential energy is minimized at all points. For vibration and buckling analysis, the loss function is constructed based on Rayleigh's principle and the fundamental frequency and the critical buckling load is extracted. A scaled hyperbolic tangent activation function for the underlying mechanical model is presented which meets the continuity requirement and alleviates the gradient vanishing/explosive problems under bending analysis. The DAEM can be easily implemented and we employed the Pytorch library and the LBFGS optimizer. A comprehensive study of the DAEM configuration is performed for several numerical examples with various geometries, load conditions, and boundary conditions.

description: We study quantum Hall effect within the framework of a newly proposed approach, which captures the principal results of some proposals. This can be established by considering a system of particles living on the non-commutative plane in the presence of an electromagnetic field and quantum statistical mechanically investigate its basic features. Solving the eigenvalue equation, we analytically derive the energy levels and the corresponding wavefunctions. These will be used, at low temperature and weak electric field, to determine the thermodynamical potential Ω^{nc} and related physical quantities. Varying Ω^{nc} with respect to the non-commutativity parameter θ, we define a new function that can be interpreted as a Ω^{nc} density. Evaluating the particle number, we show that the Hall conductivity of the system is θ-dependent. This allows us to make contact with quantum Hall effect by offering different interpretations. We study the high temperature regime and discuss the magnetism of the system. We finally show that at θ=2l_B^2, the system is sharing some common features with the Laughlin theory.

description: The extreme luminosity of gamma-ray bursts (GRBs) and their afterglows means they are detectable, in principle, to very high redshifts. Although the redshift distribution of GRBs is difficult to determine, due to incompleteness of present samples, we argue that for Swift-detected bursts the median redshift is between 2.5 and 3, with a few percent likely at z > 6. Thus, GRBs are potentially powerful probes of the era of reionization, and the sources responsible for it. Moreover, it seems likely that they can provide constraints on the star formation history of the universe, and may also help in the determination of the cosmological parameters.

description: We show that quasar microlensing magnification statistics induced by a population of point microlenses distributed according to a mass-spectrum can be very well approximated by that of a single-mass, "monochromatic", population. When the spatial resolution (physically defined by the source size) is small as compared with the Einstein radius, the mass of the monochromatic population matches the geometric mean of the mass-spectrum. Otherwise, the best-fit mass can be larger. Taking into account the degeneracy with the geometric mean, the interpretation of quasar microlensing observations under the hypothesis of a mixed population of primordial black holes and stars, makes the existence of a significant population of intermediate mass black holes ($\sim$ 100$M_\odot$) unlikely but allows, within a two-$σ$ confidence interval, the presence of a large population ($\gtrsim 40\%$ of the total mass) of substellar black holes ($\sim$ 0.01$M_\odot$).

The man in the middle: an introduction to the life and work of Gui-feng Zong-mi
Creators: name: Ainbinder, Lori Denise
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents a biographical study of the Tang Dynasty monk Gui-feng Zong-mi (780-841) together with an introduction to his thought. The biography contained herein draws upon original biographical and autobiographical sources to provide as complete a picture of the life of Zong-mi as possible within the scope of this thesis. Zong-mi defied categorization in both the manner in which he lived his life and his religious philosophy. He is simultaneously honored as a patriarch in both the Chan and Hua-yan Schools of Buddhism, while also being well-versed in the Confucian classics. As a model of Chinese Buddhist syncretism, he was able to create harmonious interaction between rival schools and religious systems in his writings and his practice. With a foot in both the exegetical and meditative traditions, Zong-mi was able to combine the best of both approaches to Buddhist religious life and philosophy. A native of Sichuan, Zong-mi entered Buddhism through the He-ze lineage of Southern Chan. He first experienced awakening while reading a passage from the Yuan-jue jing and pledged himself to explicating that text. After encountering the writings of the Fourth Hua-yan Patriarch, Cheng-guan, Zong-mi sought him out and changed his affiliation to Huayan. He maintained close ties with the Chan tradition, because he perceived the exegetical and meditative approaches were complementary. Zong-mi enjoyed a prosperous career and received numerous honors, including the purple robe granted by the emperor. Following his involvement in the Sweet Dew Incident of 835, he disappeared from view. Zong-mi was primarily driven by soteriological concerns. More specifically, he worked to develop a doctrinal basis for meditative practice and his major contributions to Chinese Buddhist thought lie in this area. The model which he developed drew from the Hua-yan vision of the harmonious interpenetration of principle and phenomena, and he used this as a basis for Chan meditative practice. This model, advocating sudden enlightenment followed by gradual cultivation, was based on his understanding of the tathagatagarbha doctrine of the Awakening of Faith.

description: We construct a manifestly gauge invariant Exact Renormalization Group for SU(N) Yang-Mills theory, in a form suitable for calculations without gauge fixing at any order of perturbation theory. The effective cutoff is incorporated via a manifestly realised spontaneously broken SU(N|N) gauge invariance. Diagrammatic methods are developed which allow the calculations to proceed without specifying the precise form of the cutoff structure. We confirm consistency by computing for the first time both the one and two loop beta function coefficients without fixing the gauge or specifying the details of the cutoff. We sketch how to incorporate quarks and thus compute in QCD. Finally we analyse the renormalization group behaviour as the renormalized coupling becomes large, and show that confinement is a consequence if and only if the coupling diverges in the limit that all modes are integrated out. We also investigate an expansion in the inverse square renormalized coupling, and show that under general assumptions it yields a new non-perturbative approximation scheme corresponding to expanding in 1/Λ_{QCD}.

description: Estimation of the density of regression errors is a fundamental issue in regression analysis and it is typically explored via a parametric approach. This article uses a nonparametric approach with the mean integrated squared error (MISE) criterion. It solves a long-standing problem, formulated two decades ago by Mark Pinsker, about estimation of a nonparametric error density in a nonparametric regression setting with the accuracy of an oracle that knows the underlying regression errors. The solution implies that, under a mild assumption on the differentiability of the design density and regression function, the MISE of a data-driven error density estimator attains minimax rates and sharp constants known for the case of directly observed regression errors. The result holds for error densities with finite and infinite supports. Some extensions of this result for more general heteroscedastic models with possibly dependent errors and predictors are also obtained; in the latter case the marginal error density is estimated. In all considered cases a blockwise-shrinking Efromovich--Pinsker density estimate, based on plugged-in residuals, is used. The obtained results imply a theoretical justification of a customary practice in applied regression analysis to consider residuals as proxies for underlying regression errors. Numerical and real examples are presented and discussed, and the S-PLUS software is available.

description: Certain two-component reaction-diffusion systems on a finite interval are known to possess mesa (box-like) steadystate patterns in the singularly perturbed limit of small diffusivity for one of the two solution components. As the diffusivity D of the second component is decreased below some critical value Dc, with Dc = O(1), the existence of a steady-state mesa pattern is lost, triggering the onset of a mesa self-replication event that ultimately leads to the creation of additional mesas. The initiation of this phenomena is studied in detail for a particular scaling limit of the Brusselator model. Near the existence threshold Dc of a single steady-state mesa, it is shown that an internal layer forms in the center of the mesa. The structure of the solution within this internal layer is shown to be governed by a certain core problem, comprised of a single non-autonomous second-order ODE. By analyzing this core problem using rigorous and formal asymptotic methods, and by using the Singular Limit Eigenvalue Problem (SLEP) method to asymptotically calculate small eigenvalues, an analytical verification of the conditions of Nishiura and Ueyema [Physica D, 130, No. 1, (1999), pp. 73-104], believed to be responsible for self-replication, is given. These conditions include: (1) The existence of a saddle-node threshold at which the steady-state mesa pattern disappears; (2) the dimple-shaped eigenfunction at the threshold, believed to be responsible for the initiation of the replication process; and (3) the stability of the mesa pattern above the existence threshold. Finally, we show that the core problem is universal in the sense that it pertains to a class of reaction-diffusion systems, including the Gierer-Meinhardt model with saturation, where mesa self-replication also occurs.

description: Decompositions of the unitary group U(n) are useful tools in quantum information theory as they allow one to decompose unitary evolutions into local evolutions and evolutions causing entanglement. Several recursive decompositions have been proposed in the literature to express unitary operators as products of simple operators with properties relevant in entanglement dynamics. In this paper, using the concept of grading of a Lie algebra, we cast these decompositions in a unifying scheme and show how new recursive decompositions can be obtained. In particular, we propose a new recursive decomposition of the unitary operator on $N$ qubits, and we give a numerical example.

Primordial He4 Abundance Constrains the Possible Time Variation of the Higgs Vacuum Expectation Value

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We constrain the possible time variation of the Higgs vacuum expectation value ($v$) by recent results on the primordial $^4He$ abundance ($Y_P$). For that, we use an analytic approach which enables us to take important issues into consideration, that have been ignored by previous works, like the $v$-dependence of the relevant cross sections of deuterium production and photodisintegration, including the full Klein- Nishina cross section. Furthermore, we take a non-equilibrium Ansatz for the freeze-out concentration of neutrons and protons and incorporate the latest results on the neutron decay. Finally, we approximate the key-parameters of the primordial $^4He$ production (the mean lifetime of the free neutron and the binding energy of the deuteron) by terms of $v\over v_0$ (where $v_0$ denotes the present theoretical estimate). Eventually, we derive the relation $Y_P \simeq 0.2479 - 5.54 (\frac{v-v_0}{v_0})^2 - 0.808~ (\frac{v-v_0}{v_0})$ and the most stringent limit on a possible time variation of $v$ is given by: $-5.4 \cdot 10^{-4} \leq \frac{v-v_0}{v_0} \leq 4.4 \cdot 10^{-4}$.

description: The Marathi language is one of the prominent languages used in India. It is predominantly spoken by the people of Maharashtra. Over the past decade, the usage of language on online platforms has tremendously increased. However, research on Natural Language Processing (NLP) approaches for Marathi text has not received much attention. Marathi is a morphologically rich language and uses a variant of the Devanagari script in the written form. This works aims to provide a comprehensive overview of available resources and models for Marathi text classification. We evaluate CNN, LSTM, ULMFiT, and BERT based models on two publicly available Marathi text classification datasets and present a comparative analysis. The pre-trained Marathi fast text word embeddings by Facebook and IndicNLP are used in conjunction with word-based models. We show that basic single layer models based on CNN and LSTM coupled with FastText embeddings perform on par with the BERT based models on the available datasets. We hope our paper aids focused research and experiments in the area of Marathi NLP.

description: The cyanides $M$CN, $M$=Cu, Ag, Au, have experimentally a structure with hexagonally packed, infinite -$M$-CN-$M$-CN- chains. Following our earlier study for AuCN, we now predict that all three $M$CN could have an alternative $M_3$C$_3$N$_3$ sheet structure of comparable energy with the known one. The valence isoelectronic systems $M$C$_2$ versus $M_3$C$_6$, $M$=Be-Ba; Zn-Hg are also studied. Now, the known dicarbides have the CaC$_2$ or MgC$_2$ chain structures. The predicted sheets lie energetically below the chains for $M$ = Zn, Cd, and Hg. All these systems are experimentally unknown. Indeed, they are clearly endothermic, compared to the elements. For some sheet structures the densities of states suggests rather small band gaps and even metallic character. When available, the experimental geometries agree well with the calculated ones for both cyanides and dicarbides.

description: The information provided by historical documents has always been indispensable in the transmission of human civilization, but it has also made these books susceptible to damage due to various factors. Thanks to recent technology, the automatic digitization of these documents are one of the quickest and most effective means of preservation. The main steps of automatic text digitization can be divided into two stages, mainly: character segmentation and character recognition, where the recognition results depend largely on the accuracy of segmentation. Therefore, in this study, we will only focus on the character segmentation of historical Chinese documents. In this research, we propose a model named HRCenterNet, which is combined with an anchorless object detection method and parallelized architecture. The MTHv2 dataset consists of over 3000 Chinese historical document images and over 1 million individual Chinese characters; with these enormous data, the segmentation capability of our model achieves IoU 0.81 on average with the best speed-accuracy trade-off compared to the others. Our source code is available at https://github.com/Tverous/HRCenterNet.

description: A simple vibrational model of heat transfer in two-dimensional (2D) fluids relates the heat conductivity coefficient to the longitudinal and transverse sound velocities, specific heat, and the mean interatomic separation. This model is demonstrated not to contradict the available experimental and numerical data on heat transfer in 2D complex plasma layers. Additionally, the heat conductivity coefficient of a 2D one-component plasma with a logarithmic interaction is evaluated.

A flood of tears: melancholy as style in English Music and Poetry circa 1600
Creators: name: Hurvitz, Nathaniel Joseph

description: The Elizabethan interest in melancholy as a physio-psychological condition is well-documented. Melancholy may also be regarded as designating a musical style in England around the turn of the seventeenth century, a style which this thesis attempts to describe in terms of music and poetry. English secular vocal music of the late Elizabethan and early Jacobean periods contains a fairly small but significant portion whose poetic texts focus on "dark" themes, such as death, night, tears, grief, and despair. Frequently, no cause is mentioned for the woe which the poet describes, and this lack of external cause points to melancholy as the source of the aggrieved state. Melancholy was believed to be internally caused by an over-abundance of one of the four humours (black bile) in the body. Traditionally regarded as the least desirable of the humours, melancholy was revalued as the result of the translation of Aristotle's Problemata by Florentine scholars around the turn of the sixteenth century, and became regarded as a condition which could produce genius and inspiration. The revalued view of melancholy was introduced to England near the end of the sixteenth century, and gave rise to a style of poetry and music which reflects the Florentine revaluation. George Chapman's Shadow of Night (1594) appears to be the literary manifesto of the revalued melancholic, and a large proportion of melancholic poetry set to music in the period shows close thematic commonalities with Chapman's poem. John Dowland was the leading composer of melancholic music in England at the turn of the seventeenth century, and his songs, particularly the song "Flow my tears" (1600), set a musical and poetic standard which was to be emulated and parodied extensively by his contemporaries. "Flow my tears" uses motivic material which is found throughout Dowland's melancholic compositions. A study of the music of Dowland's fellow composers reveals that the latter were keenly aware of the melancholic significance of these musical motives, because they conspicuously employ them in their own melancholic compositions. This thesis examines the use of these motives in Dowland's melancholic works, as well as in contemporaneous lute songs, madrigals, and instrumental compositions. A broad survey is undertaken of printed secular music (and to a lesser degree, of manuscript sources) in England between c. 1590 and c. 1620. Possible sources and antecedents to Dowland are investigated. It is revealed that the correspondence of specific poetic and musical devices results in a distinctive poetico-musical style which appears to trace a virtually direct line to Dowland. It is shown that this trend, which begins as a peripheral subcurrent, evolves during the period into a movement which deserves to be regarded as a musico-poetic style in its own right.

description: We present a finite-size scaling analysis of high-statistics Monte Carlo simulations of the three-dimensional randomly site-diluted and bond-diluted Ising model. The critical behavior of these systems is affected by slowly-decaying scaling corrections which make the accurate determination of their universal asymptotic behavior quite hard, requiring an effective control of the scaling corrections. For this purpose we exploit improved Hamiltonians, for which the leading scaling corrections are suppressed for any thermodynamic quantity, and improved observables, for which the leading scaling corrections are suppressed for any model belonging to the same universality class. The results of the finite-size scaling analysis provide strong numerical evidence that phase transitions in three-dimensional randomly site-diluted and bond-diluted Ising models belong to the same randomly dilute Ising universality class. We obtain accurate estimates of the critical exponents, $ν=0.683(2)$, $η=0.036(1)$, $α=-0.049(6)$, $γ=1.341(4)$, $β=0.354(1)$, $δ=4.792(6)$, and of the leading and next-to-leading correction-to-scaling exponents, $ω=0.33(3)$ and $ω_2=0.82(8)$.

description: In our multi-agent model agents generate wealth from repeated interactions for which a prisoner's dilemma payoff matrix is assumed. Their gains are taxed by a government at a rate $α$. The resulting budget is spent to cover administrative costs and to pay a bonus to cooperative agents, which can be identified correctly only with a probability $p$. Agents decide at each time step to choose either cooperation or defection based on different information. In the local scenario, they compare their potential gains from both strategies. In the global scenario, they compare the gains of the cooperative and defective subpopulations. We derive analytical expressions for the critical bonus needed to make cooperation as attractive as defection. We show that for the local scenario the government can establish only a medium level of cooperation, because the critical bonus increases with the level of cooperation. In the global scenario instead full cooperation can be achieved once the cold-start problem is solved, because the critical bonus decreases with the level of cooperation. This allows to lower the tax rate, while maintaining high cooperation.

description: The Rayleigh-Ritz (RR) method finds the stationary values, called Ritz values, of the Rayleigh quotient on a given trial subspace as approximations to eigenvalues of a Hermitian operator $A$. If the trial subspace is $A$-invariant, the Ritz values are exactly some of the eigenvalues of $A$. Given two subspaces $\X$ and $\Y$ of the same finite dimension, such that $\X$ is $A$-invariant, the absolute changes in the Ritz values of $A$ with respect to $\X$ compared to the Ritz values with respect to $\Y$ represent the RR absolute eigenvalue approximation error. Our first main result is a sharp majorization-type RR error bound in terms of the principal angles between $\X$ and $\Y$ for an arbitrary $A$-invariant $\X$, which was a conjecture in [SIAM J. Matrix Anal. Appl., 30 (2008), pp. 548-559]. Second, we prove a novel type of RR error bound that deals with the products of the errors, rather than the sums. Third, we establish majorization bounds for the relative errors. We extend our bounds to the case $\dim\X\leq\dim\Y

description: The possibilities to accelerate vortex electrons with orbital angular momentum (OAM) to relativistic energies and to produce vortex ions, protons, and other charged particles crucially depend on whether the OAM is conserved during the acceleration and on how phase space of the wave packet evolves. We show that both the OAM and a mean emittance of the packet, the latter obeying the Schrödinger uncertainty relation, are conserved in axially symmetric fields of electric and magnetic lenses, typical for accelerators and electron microscopes, as well as in Penning traps, while a linear approximation of weakly inhomogeneous fields works much better for single packets than for classical beams. We analyze quantum dynamics of the packet's rms radius $\langleρ^2\rangle$, relate this dynamics to a generalized form of the van Cittert-Zernike theorem, applicable at arbitrary distances from a source and for non-Gaussian packets, and adapt the Courant-Snyder formalism to describe the evolution of the wave packet's phase space. The vortex particles can therefore be accelerated, focused, steered, trapped, and even stored in azimuthally symmetric fields and traps, somewhat analogously to the classical angular-momentum-dominated beams. Moreover, we give a quantum version of the Busch theorem, which states how one can produce vortex electrons with a magnetized cathode during either field- or photoemission, as well as vortex ions and protons by using a magnetized stripping foil employed to change a charge state of ions. Spatial coherence of the packets plays a crucial role in these applications and we provide the necessary estimates for particles of different masses.

description: Non-minimal actions with matter represented by a scalar field coupled to gravity are considered in the context of a homogeneous and isotropic universe. The coupling is of the form $-ξ/2 ϕ^2 R$. The possibility of successful inflation is investigated taking into account features of loop cosmology. For that end a conformal transformation is performed. That brings the theory into the standard minimally coupled form (Einstein frame) with some effective field and its potential. Both analytical and numerical estimates show that a negative coupling constant is preferable for successful inflation. Moreover, provided fixed initial conditions, larger $|ξ|$ leads to a greater number of {\em e}-folds. The latter is obtained for a reasonable range of initial conditions and the coupling parameter and indicates a possibility for successful inflation.

description: The key idea behind the renormalization group (RG) transformation is that properties of physical systems with very different microscopic makeups can be characterized by a few universal parameters. However, finding the optimal RG transformation remains difficult due to the many possible choices of the weight factors in the RG procedure. Here we show, by identifying the conditional distribution in the restricted Boltzmann machine (RBM) and the weight factor distribution in the RG procedure, an optimal real-space RG transformation can be learned without prior knowledge of the physical system. This neural Monte Carlo RG algorithm allows for direct computation of the RG flow and critical exponents. This scheme naturally generates a transformation that maximizes the real-space mutual information between the coarse-grained region and the environment. Our results establish a solid connection between the RG transformation in physics and the deep architecture in machine learning, paving the way to further interdisciplinary research.
