description: In the first chapter we develop a theoretical model investigating food consumption and body weight with a novel assumption regarding human caloric expenditure (i.e. metabolism), in order to investigate why individuals can be rationally trapped in an excessive weight equilibrium and why they struggle to lose weight even when offered incentives for weight-loss. This assumption allows the theoretical model to have multiple equilibria and to provide an explanation for why losing weight is so difficult even in the presence of incentives, without relying on rational addiction, time-inconsistency preferences or bounded rationality. In addition to this result we are able to characterize under which circumstances a temporary incentive can create a persistent weight loss. In the second chapter we investigate the possible contributions that social norms and peer effects had on the spread of obesity. In recent literature peer effects and social norms have been characterized as important pathways for the biological and behavioral spread of body weight, along with decreased food prices and physical activity. We add to this literature by proposing a novel concept of social norm related to what we define as social distortion in weight perception. The theoretical model shows that, in equilibrium, the effect of an increase in peers' weight on i's weight is unrelated to health concerns while it is mainly associated with social concerns. Using regional data from England we prove that such social component is significant in influencing individual weight. In the last chapter we investigate the relationship between body weight and employment probability. Using a semi-parametric regression we show that men and women employment probability do not follow a linear relationship with body mass index (BMI) but rather an inverted U-shaped one, peaking at a BMI way over the clinical threshold for overweight.
Piezomagnetism in ferromagnetic superconductors

description: The appearance of magnetization during the application of mechanical stress and the creation of elastic deformation during the application of a magnetic field are two fundamental properties of piezomagnetic materials. The symmetry of superconducting ferromagnets UGe_2, URhGe, UCoGe allows piezomagnetism. In addition to conventional piezomagnetic properties occurring in both normal and superconducting states, superconducting state of these piezomagnets has its own specificity. Unlike conventional superconductors, in uranium ferromagnets, the critical transition temperature to the superconducting state changes its value when the direction of the field changes to the opposite.

description: This paper aims to provide a reasoned account of the literary output, published and unpublished, attributable to Giorgio Valla, including both his translations from Greek and his independent work, as well as texts that for convenience he had printed under a pseudonym or that appeared as written or edited by his adopted son Giovan Pietro Cademosto, an otherwise unknown figure who was responsible for serious alterations, if not actual falsifications, in the posthumously published writings of his father. How far we still are from a full knowledge of this humanist’s work is shown by the recent discovery of manuscripts that transmit writings of his whose existence was utterly unknown, such as the treatises on spelling and prosody De recto modo scribendi and De syllabarum dinoscenda quantitate.

description: We address the general problem of the luminosity-specific planetary nebula (PN) number, defined as alpha = N(PN)/L(gal), and its relationship with age and metallicity of the parent stellar population. Our analysis relies on population synthesis models for simple stellar populations and more elaborated galaxy models along the full star-formation range of the Hubble morphological sequence. This theoretical framework is compared with the updated census of the PN population in Local Group galaxies and external ellipticals in the Leo group, and the Virgo and Fornax clusters.

description: We theoretically and numerically study the effects of thermal noise on pulses in backwards Stimulated Brillouin Scattering (SBS). Using a combination of stochastic calculus and numerical methods, we derive a theoretical model that can be used to quantitatively predict noise measurements. We study how the optical pulse configuration, including the input powers of the pump and Stokes fields, pulse durations and interaction time, affects the noise in the output Stokes field. We investigate the effects on the noise of the optical loss and waveguide length, and we find that the signal-to-noise ratio can be significantly improved, or reduced, for specific combinations of waveguide properties and pulse parameters.

EXTERNAL REPRODUCTIVE STRUCTURES OF MALE SURFPERCHES (EMBIOTOCIDAE)

Subjects: fish reproduction

description: The surfperches (Embiotocidae) are internally inseminating fish species that are divided into two sub-families, the Amphistichinae and Embiotocinae. Male embiotocids have been reported to have a ventrally located genital papilla. Additionally, male Amphistichinae species have gland-like structures that develop on the mid-portion of the anal fin and male Embiotcinae have flask organs that develop on the anterior portion of the anal fin. Although courtship behaviors have been previously observed in some species, the structure (i.e., genital papilla, anal fin structures) that is used during copulation is currently unknown. In the current study, the external morphology of 19 Embiotocidae species was examined. Paraffin histology was used to investigate the walleye surfperch (Hyperprosopon argenteum), black perch (Embiotoca jacksoni), and dwarf perch (Micrometrus minimus) external structures including the genital papilla, gland-like structures, and flask organs to determine tissue composition and elucidate their function. The genital papilla was directly connected to the internal reproductive structures and thus is likely to be associated with sperm transfer. Because the genital papilla was found to have both excretory and reproductive ductal openings, it should be referred to as a urogenital papilla. Cleared and stained male anal fins differed from female anal fins and the modified fin rays likely structurally support the anal fin structures and thus are sexually dimorphic traits. Walleye surfperch gland-like structures and the black and dwarf perch flask organs consisted of glandular epithelial tissue, and it is proposed that they be referred to collectively as anal fin glands. The anal fin glands in males recrudesced during the breeding season and regressed during the non-breeding season, and thus are likely to be involved in reproduction. Overall, this study contributes to our understanding of surfperch internal and external reproductive structures, external modifications, and enhances our knowledge of internally inseminating, viviparous teleost species.

The photometry of these objects was obtained using a template subtraction method to eliminate galaxy light contamination during aperture photometry. We show the optical light curves of these supernovae out to epochs of up to ~640 days after the explosion of the supernova. We show a linear decline in these data during the epoch of 200-500 days after explosion with the decline rate in the B,V,& R bands equal to about 1.4 mag/100 days, but the decline rate of the I-band is much shallower at 0.94 mag/100 days.

description: A total lunar eclipse is plausible to have an influence on the variation of some environmental physical parameters, specifically on the conditions of the sky brightness, humidity and temperature. During the eclipse on 14$^{th}$-15$^{th}$ April 2014, these parameters were measured through a photometer and a weather station. The obtained results allow the comparison, practically, of the optimal conditions for observational astronomy work in the Tatacoa desert and therefore to certify it as suitable perfect place to develop night sky astronomical observations. This investigation determined, to some extent, the suitability of this place to carry out astronomical work and research within the optical range. Thus, the changes recorded during the astronomical phenomenon allowed the classification of the sky based on the Bortle Scale

description: The present study examines the interfacial properties of carbon fiber biobased resin composites by comparing the test methods such as the single fiber fragmentation test, fiber push-out test, and interlaminar shear strength test. The composites were fabricated using a cold vacuum-assisted resin infusion method for the preparation of fiber push-out and interlaminar shear test specimens. The interfacial adhesion from the three different test methods is analyzed and compared to determine their relative effectiveness in evaluating interfacial adhesion. Plasma treatment is performed on the carbon fibers and the interfacial shear stress is evaluated by conducting the push-out test. The surface characterization of the carbon fibers is done by scanning electron microscopy and x-ray photoelectron spectroscopy to investigate the influence of the plasma treatment on the fiber surface. Plasma treatment resulted in significant improvement in the interfacial adhesion between the fiber and matrix. Highlights • Analysis and comparison of interfacial adhesion by several test methods. • Single fiber fragmentation and push-out tests with IFSS of 40.5 and 42.2 MPa. • Plasma surface treatment improved the IFSS by 88.1%. • Surface characterization of treated and untreated fibers by SEM and XPS

description: The screening of an impurity spin by conduction electrons is associated with the formation of a large Kondo screening cloud, of size xi_K. We study the quantum entanglement between a region of size r surrounding the impurity and the rest of the sample, (of total size R) using Density Matrix Renormalization Group and analytic methods. The corresponding "impurity entanglement entropy", S_{imp}, is shown to be a universal scaling function of r/xi_K and r/R. We calculate this universal function using Fermi liquid theory in the regime xi_K << r.

Closed-loop investigation of the dynamical properties of cardiomyocyte electrophysiology by means of Dynamic clamp and Mathematical modelling

Subjects: ING-INF/06 Bioingegneria elettronica e informatica

description: The research field of my PhD concerns mathematical modeling and numerical simulation, applied to the cardiac electrophysiology analysis at a single cell level. This is possible thanks to the development of mathematical descriptions of single cellular components, ionic channels, pumps, exchangers and subcellular compartments. Due to the difficulties of vivo experiments on human cells, most of the measurements are acquired in vitro using animal models (e.g. guinea pig, dog, rabbit). Moreover, to study the cardiac action potential and all its features, it is necessary to acquire more specific knowledge about single ionic currents that contribute to the cardiac activity. Electrophysiological models of the heart have become very accurate in recent years giving rise to extremely complicated systems of differential equations. Although describing the behavior of cardiac cells quite well, the models are computationally demanding for numerical simulations and are very difficult to analyze from a mathematical (dynamical-systems) viewpoint. Simplified mathematical models that capture the underlying dynamics to a certain extent are therefore frequently used.
The results presented in this thesis have confirmed that a close integration of computational modeling and experimental recordings in real myocytes, as performed by dynamic clamp, is a useful tool in enhancing our understanding of various components of normal cardiac electrophysiology, but also arrhythmogenic mechanisms in a pathological condition, especially when fully integrated with experimental data.

description: We investigate the quantum squeezing of slow-light solitons generated in a $Λ$-shaped three-level atomic system working under condition of electromagnetically induced transparency (EIT). We show that due to the giant Kerr nonlinearity contributed from the EIT effect, significant quantum squeezing of the slow-light soliton can be realized within a short propagation distance. The results reported here are helpful for understanding the quantum property of slow-light solitons and for realizing light squeezing via EIT in cold atomic gases experimentally.

Nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates in a triple-well potential

Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study nonlinear dynamics of Rydberg-dressed Bose-Einstein condensates (BECs) trapped in a triple-well potential in the semiclassical limit. The Rydberg-dressed BECs experience a long-range soft-core interaction, giving rise to strong nearest and next-nearest neighbor interactions in the triple-well system. Using mean-field Gross-Pitaevskii (GP) equations, we show that lower branches of the eigenspectra exhibit loops and level-crossings when the soft-core interaction is strong. The direct level-crossings eliminate the possibility of adiabatic Landau-Zener transitions when tilting of the triple-well potential. We demonstrate that the long-range interaction allows for self-trapping in one, two, or three wells, in a far more controllable manor than BECs with short-range or dipolar interactions. Exact quantum simulations of the three-well Bose-Hubbard model indicate that self-trapping and nonadiabatic transition can be observed with less than a dozen bosons. Our study is relevant to current research into collective excitation and nonlinear dynamics of Rydberg-dressed atoms.

A Significant Medical Manuscript Belonging to Valla: the Mutinensis α.U.9.4 (gr. 61)
Creators: name: Miguet, Thibault
Publisher: name: Medicina nei secoli: Journal of history of medicine and medical humanities
Year: 2024

description: The Mutinensis α.U.9.4 (gr. 61) is a 15th century manuscript containing several classical and Byzantine medical texts and excerpts. It is well-known that it was used by Valla for his Latin translation of Symeon Seth’s Syntagma de alimentorum facultatibus. But the volume itself received insufficient scholarly interest, whether it be from a codicological or a philological point of view, especially as far as the other medical texts are concerned. This contribution aims at examining in detail the entire manuscript and Valla’s reading of it in order to show that the Mutinensis can be replaced in a flourishing context of other manuscripts, scribes and readers and that it thus represents a key moment in medical humanism. In particular, the relationship between the Mutinensis (and its copyist, Emmanuel Zacharides) and volumes copied by Demetrios Damilas, sheds a new light on connections that hadn’t been insisted upon in previous studies.

description: The solar corona is a complex system, with nonisothermal plasma and being in the self-gravitating field of the Sun. So the corona plasma is not only a nonequilibrium system but also a nonextensive one. We estimate the parameter of describing the degree of nonextensivity of the corona plasma and study the generalization of the solar wind speed theory in the framework of nonextensive statistical mechanics. It is found that, when use Chapman's corona model (1957) as the radial distribution of the temperature in the corona, the nonextensivity reduces the gas pressure outward and thus leads a significant deceleration effect on the radial speed of the solar wind.

description: The Schrödinger-Newton system is a nonlinear system obtained by coupling together the linear Schrödinger equation of quantum mechanics with the Poisson equation of Newtonian mechanics. In the present work we will investigate the effects of a cosmological constant (dark energy or vacuum fluctuation) on the Schrödinger-Newton system, by modifying the Poisson equation through the addition of a new term. The corresponding Schrödinger-Newton-$Λ$ system cannot be solved exactly, and therefore for its study one must resort to either numerical or semianalytical methods. In order to obtain a semianalytical solution of the system we apply the Adomian Decomposition Method, a very powerful method used for solving a large class of nonlinear ordinary and partial differential equations. Moreover, the Adomian series are transformed into rational functions by using the Padé approximants. The semianalytical approximation is compared with the full numerical solution, and the effects of the dark energy on the structure of the Newtonian quantum system are investigated in detail.

description: We present numerical simulations investigating the interaction of AGN jets with galaxy clusters, for the first time taking into account the dynamic nature of the cluster gas and detailed cluster physics. The simulations successfully reproduce the observed morphologies of radio sources in clusters. We find that cluster inhomogeneities and large scale flows have significant impact on the morphology of the radio source and cannot be ignored a-priori when investigating radio source dynamics. Morphological comparison suggests that the gas in the centres of clusters like Virgo and Abell 4059 shows significant shear and/or rotation. We find that shear and rotation in the intra-cluster medium move large amounts of cold material back into the path of the jet, ensuring that subsequent jet outbursts encounter a sufficient column density of gas to couple with the inner cluster gas, thus alleviating the problem of evacuated channels discussed in the recent literature. The same effects redistribute the excess energy Delta_E deposited by the jets, making the distribution of Delta_E at late times consistent with being isotropic.

description: In this paper we address the problem of building a class of robust factorization algorithms that solve for the shape and motion parameters with both affine (weak perspective) and perspective camera models. We introduce a Gaussian/uniform mixture model and its associated EM algorithm. This allows us to address robust parameter estimation within a data clustering approach. We propose a robust technique that works with any affine factorization method and makes it robust to outliers. In addition, we show how such a framework can be further embedded into an iterative perspective factorization scheme. We carry out a large number of experiments to validate our algorithms and to compare them with existing ones. We also compare our approach with factorization methods that use M-estimators.
Giorgio Valla and His Latin Translations of Galen

Publisher: name: Medicina nei secoli: Journal of history of medicine and medical humanities
Year: 2024

description: By means of his Latin translations Giorgio Valla contributed to the rediscovery of ancient Greek medicine in the Renaissance. In particular, he was the first to publish humanist translations of Galen ahead of his contemporaries Niccolò Leoniceno (1428-1524) and Lorenzo Lorenzi (ca. 1460-1502). In 1483 Valla published the translation of De sectis, followed by those of De inaequali intemperie, De optima corporis constitutione, De bono corporis habitu, Praesagium experientia confirmatum, De venae sectione, and De praenotione in 1498. After his death, two other translations by Valla were printed in the fourth complete edition of Galen of 1515-16, namely those of the ps.-Galenic Quaesita in Hippocratis de urinis and De urinae significatione ex Hippocrate. These last two translations came from Valla’s encyclopedia De expetendis et fugiendis rebus, posthumously published by Aldo Manuzio in 1501, which contains translations of Galenic and ps.-Galenic works, or sections of them, including the aforementioned De sectis, Praesagium experientia confirmatum, and De venae sectione. This article presents Valla’s translations of the Galenic corpus and their impact in the complete editions of Galen; moreover, it identifies the Greek sources of the translations, that is manuscripts owned by Valla (Modena, BEU α.P.5.20 = Puntoni 109, α.U.9.4 = Puntoni 61, and Naples, BN III.C.2); finally, it analyses linguistic and stylistic features in Valla’s translations, especially in those attested in two redactions, aiming to shed light on the chronological relations among them.

description: Accountability is an often called for property of technical systems. It is a requirement for algorithmic decision systems, autonomous cyber-physical systems, and for software systems in general. As a concept, accountability goes back to the early history of Liberalism and is suggested as a tool to limit the use of power. This long history has also given us many, often slightly differing, definitions of accountability. The problem that software developers now face is to understand what accountability means for their systems and how to reflect it in a system's design. To enable the rigorous study of accountability in a system, we need models that are suitable for capturing such a varied concept. In this paper, we present a method to express and compare different definitions of accountability using Structural Causal Models. We show how these models can be used to evaluate a system's design and present a small use case based on an autonomous car.

description: We study the small time path behavior of double stochastic integrals of the form $\int_0^t(\int_0^rb(u) dW(u))^T dW(r)$, where $W$ is a $d$-dimensional Brownian motion and $b$ is an integrable progressively measurable stochastic process taking values in the set of $d\times d$-matrices. We prove a law of the iterated logarithm that holds for all bounded progressively measurable $b$ and give additional results under continuity assumptions on $b$. As an application, we discuss a stochastic control problem that arises in the study of the super-replication of a contingent claim under gamma constraints.

description: The Pencil Code is a highly modular physics-oriented simulation code that can be adapted to a wide range of applications. It is primarily designed to solve partial differential equations (PDEs) of compressible hydrodynamics and has lots of add-ons ranging from astrophysical magnetohydrodynamics (MHD) to meteorological cloud microphysics and engineering applications in combustion. Nevertheless, the framework is general and can also be applied to situations not related to hydrodynamics or even PDEs, for example when just the message passing interface or input/output strategies of the code are to be used. The code can also evolve Lagrangian (inertial and noninertial) particles, their coagulation and condensation, as well as their interaction with the fluid.

description: We consider the superconformal quantum mechanics associated to BPS black holes in type IIB Calabi-Yau compactifications. This quantum mechanics describes the dynamics of D-branes in the near-horizon attractor geometry of the black hole. In many cases, the black hole entropy can be found by counting the number of chiral primaries in this quantum mechanics. Both the attractor mechanism and notions of marginal stability play important roles in generating the large number of microstates required to explain this entropy. We compute the microscopic entropy explicitly in a few different cases, where the theory reduces to quantum mechanics on the moduli space of special Lagrangians. Under certain assumptions, the problem may be solved by implementing mirror symmetry as three T-dualities: this is essentially the mirror of a calculation by Gaiotto, Strominger and Yin. In some simple cases, the calculation may be done in greater generality without resorting to conjectures about mirror symmetry. For example, the K3xT^2 case may be studied precisely using the Fourier-Mukai transform.

description: The focus of this thesis is discovering disease signatures using association rule mining. A disease signature is the common characteristics that may give the disease patients a distinct identity. In this thesis, we are specifically analyzing the dynamic gaits of Parkinson's patients and healthy controls to identify potential disease signatures. This can be useful as such signatures can be considered potential indicators of the disease. Since there is no preemptive test or marker for Parkinson's disease diagnoses, these types of signatures can help physicians be proactive. Currently a diagnosis of Parkinson's disease is primarily based on a patient's medical history and some neurological exams which include analysis of movement and balance [1]. Our approach can be generalized to any type of gait analysis.  We use association rule mining as a building block to identify signatures. We tested our approach on the dynamic gaits of 15 Parkinson patients and 16 healthy controls. We used Coron [2] and Weka [3] systems in our implementation. The data was obtained from PhysioBank [4], a public source for biomedical data. Our results identified significant signatures for Parkinson's disease in approximately 50% of the data. We also identified some overlap in signatures between Parkinson's patients and healthy controls, indicating that gait speed and height may be important factors in discovering signatures. We validated our results using Pearson correlation and found that correlation increases substantially in Parkinson's patients, indicating that the signatures are valid, especially in Parkinson's patients.

description: Unitary coupled cluster (UCC), originally developed as a variational alternative to the popular traditional coupled cluster method, has seen a resurgence as a functional form for use on quantum computers. However, the number of excitors present in the ansatz often presents a barrier to implementation on quantum computers. Given the natural sparsity of wavefunctions obtained from Quantum Monte Carlo methods, we consider here a stochastic solution to the UCC problem. Using the Coupled Cluster Monte Carlo framework, we develop cluster selection schemes that capture the structure of the UCC wavefunction, as well as its Trotterized approximation, and use these to solve the corresponding projected equations. Due to the fast convergence of the equations with order in the cluster expansion, this approach scales polynomially with the size of the system. Unlike traditional UCC implementations, our approach naturally produces a non-variational estimator for the energy in the form of the projected energy. For UCCSD in small systems, we find this agrees well with the expectation value of the energy and, in the case of two electrons, with full configuration interaction results. For the larger N$_2$ system, the two estimators diverge, with the projected energy approaching the coupled cluster result, while the expectation value is close to results from traditional UCCSD.

description: We present lattice results for spin-1/2 fermions at unitarity, where the effective range of the interaction is zero and the scattering length is infinite. We measure the spatial coherence of difermion pairs for a system of 6, 10, 14, 18, 22, 26 particles with equal numbers of up and down spins in a periodic cube. Using Euclidean time projection, we analyze ground state properties and transient behavior due to low-energy excitations. At asymptotically large values of t we see long-range order consistent with spontaneously broken U(1) fermion-number symmetry and a superfluid ground state. At intermediate times we see exponential decay in the t-dependent signal due to an unknown low-energy excitation. We probe this low-energy excitation further by calculating two-particle correlation functions. We find that the excitation has the properties of a chain of particles extending across the periodic lattice.
