Galactic Star Formation Rates

description: The interstellar medium (ISM) is the heart of the cosmic evolution, where the cosmic baryonic cycle ends with star formation and begins again by stellar feedback. Therefore, star formation rates (SFRs) are a critical property to understand galaxy formation and evolution. Observationally, star-forming galaxies generally show much longer gas depletion timescales than global and local dynamical timescales, in contrast to the fact that the ISM is highly dissipative with very short turbulence dissipation and cooling times. In this talk, I will explain why star formation is inefficient in gas consumption and how galactic SFRs are regulated by efficient stellar feedback. Based on a theoretical framework for self-regulation of SFRs, I will present quantitative relations between SFR surface density and gas pressure, which is in balance with the weight of gas. Therefore, the weight of gas (or dynamical equilibrium pressure) can be used to predict SFRs from galactic properties. Finally, I will show a suite of self-consistent magnetohydrodynamics simulations to test, refine, and calibrate the theory.

description: We present a detailed study of various aspects of Spinor-Vector duality in Heterotic string compactifications and expose its origin in terms of the internal conformal field theory. In particular, we illustrate the main features of the duality map by using simple toroidal orbifolds preserving N_4 = 1 and N_4 = 2 spacetime supersymmetries in four dimensions. We explain how the duality map arises in this context by turning on special values of the Wilson lines around the compact cycles of the manifold. We argue that in models with N_4 = 2 spacetime supersymmetry, the interpolation between the Spinor-Vector dual vacua can be continuously realized. We trace the origin of the Spinor-Vector duality map to the presence of underlying N = (2, 2) and N = (4, 4) SCFTs, and explicitly show that the induced spectral-flow in the twisted sectors is responsible for the observed duality. The isomorphism between current algebra representations gives rise to a number of chiral character identities, reminiscent of the recently-discovered MSDS symmetry.

description: It is known that entangled mixed states that are positive under partial transposition (PPT states) must have rank at least four. In a previous paper we presented a classification of rank four entangled PPT states which we believe to be complete. In the present paper we continue our investigations of the low rank entangled PPT states. We use perturbation theory in order to construct rank five entangled PPT states close to the known rank four states, and in order to compute dimensions and study the geometry of surfaces of low rank PPT states. We exploit the close connection between low rank PPT states and product vectors. In particular, we show how to reconstruct a PPT state from a sufficient number of product vectors in its kernel. It may seem surprising that the number of product vectors needed may be smaller than the dimension of the kernel.

description: We present the Migdal In Galactic Dark mAtter expLoration (MIGDAL) experiment aiming at the unambiguous observation and study of the so-called Migdal effect induced by fast-neutron scattering. It is hoped that this elusive atomic process can be exploited to enhance the reach of direct dark matter search experiments to lower masses, but it is still lacking experimental confirmation. Our goal is to detect the predicted atomic electron emission which is thought to accompany nuclear scattering with low, but calculable, probability, by deploying an Optical Time Projection Chamber filled with a low-pressure gas based on CF$_4$. Initially, pure CF$_4$ will be used, and then in mixtures containing other elements employed by leading dark matter search technologies -- including noble species, plus Si and Ge. High resolution track images generated by a Gas Electron Multiplier stack, together with timing information from scintillation and ionisation readout, will be used for 3D reconstruction of the characteristic event topology expected for this process -- an arrangement of two tracks sharing a common vertex, with one belonging to a Migdal electron and the other to a nuclear recoil. Different energy-loss rate distributions along both tracks will be used as a powerful discrimination tool against background events. In this article we present the design of the experiment, informed by extensive particle and track simulations and detailed estimations of signal and background rates. In pure CF$_4$ we expect to observe 8.9 (29.3) Migdal events per calendar day of exposure to an intense D-D (D-T) neutron generator beam at the NILE facility located at the Rutherford Appleton Laboratory (UK). With our nominal assumptions, 5$σ$ median discovery significance can be achieved in under one day with either generator.

description: Pattern formation in reaction-diffusion systems is of great importance in surface micro-patterning [Grzybowski et al. Soft Matter. 1, 114 (2005)], self-organization of cellular micro-organisms [Schulz et al. Annu. Rev. Microbiol. 55, 105 (2001)] and in developmental biology [Barkai et al. FEBS Journal 276, 1196 (2009)]. In this work, we apply the Lattice Boltzmann method (LBM) to study pattern formation in reaction-diffusion systems. As a first methodological step, we consider the case of a single species undergoing transformation reaction and diffusion. In this case, we perform a third-order Chapman-Enskog multiscale expansion and study the dependence of the Lattice Boltzmann truncation error on the diffusion coefficient and the reaction rate. These findings are in good agreement with numerical simulations. Furthermore, taking the Gray-Scott model as a prominent example, we provide evidence for the maturity of the LBM in studying pattern formation in non-linear reaction-diffusion systems. For this purpose, we perform linear stability analysis of the Gray-Scott model and determine the relevant parameter range for pattern formation. Lattice Boltzmann simulations allow not only to test the validity of the linear stability phase diagram including Turing and Hopf instabilities, but also permit going beyond the linear stability regime, where large perturbations give rise to interesting dynamical behavior such as the so called self replicating spots. We also show that the length scale of the patterns may be tuned by rescaling all relevant diffusion coefficients in the system with the same factor while letting all the reaction constants unchanged.

Ability of error correlations to improve the performance of variational quantum algorithms

Year: 2022

description: The quantum approximate optimization algorithm (QAOA) has the potential of providing a useful quantum advantage on noisy intermediate-scale quantum (NISQ) devices. The effects of uncorrelated noise on variational quantum algorithms such as QAOA have been studied intensively. Recent experimental results, however, show that the errors impacting NISQ devices are significantly correlated. We introduce a model for both spatially and temporally (non-Markovian) correlated errors based on classical environmental fluctuators. The model allows for the independent variation of the marginalized spacetime-local error probability and the correlation strength. Using this model, we study the effects of correlated stochastic noise on QAOA. We find evidence that the performance of QAOA improves as the correlation time or correlation length of the noise is increased at fixed local error probabilities. This shows that noise correlations in themselves need not be detrimental for NISQ algorithms such as QAOA.

Spatially Resolving Galaxy Environmental Quenching in the SAMI Galaxy Survey

description: In order to identify how spatially resolved star formation depends on environment, we use the unitless scale-radius ratio (r50,Hα/r50,cont) (building on earlier work of Schaefer et al. 2017). We will use this metric to investigate quenching across a much enlarged dynamic range of environment (from clusters to the field), and with the full SAMI Galaxy Survey sample. This unitless scale-radius ratio shows the ratio of ongoing star formation to previous (or quenched) star formation. We will show our results using different environment density (group mass, local density, projected phase-space) and as a function of galaxy mass. We will also combine our measurements with other star formation rate indicators from the GAMA Survey (e.g. UV, far infrared) to place better contraints on the timescale of quenching in our galaxies.

description: Objectives: The purpose is to apply a previously validated deep learning algorithm to a new thyroid nodule ultrasound image dataset and compare its performances with radiologists. Methods: Prior study presented an algorithm which is able to detect thyroid nodules and then make malignancy classifications with two ultrasound images. A multi-task deep convolutional neural network was trained from 1278 nodules and originally tested with 99 separate nodules. The results were comparable with that of radiologists. The algorithm was further tested with 378 nodules imaged with ultrasound machines from different manufacturers and product types than the training cases. Four experienced radiologists were requested to evaluate the nodules for comparison with deep learning. Results: The Area Under Curve (AUC) of the deep learning algorithm and four radiologists were calculated with parametric, binormal estimation. For the deep learning algorithm, the AUC was 0.69 (95% CI: 0.64 - 0.75). The AUC of radiologists were 0.63 (95% CI: 0.59 - 0.67), 0.66 (95% CI:0.61 - 0.71), 0.65 (95% CI: 0.60 - 0.70), and 0.63 (95%CI: 0.58 - 0.67). Conclusion: In the new testing dataset, the deep learning algorithm achieved similar performances with all four radiologists. The relative performance difference between the algorithm and the radiologists is not significantly affected by the difference of ultrasound scanner.

description: Modeling viral dynamics in HIV/AIDS studies has resulted in a deep understanding of pathogenesis of HIV infection from which novel antiviral treatment guidance and strategies have been derived. Viral dynamics models based on nonlinear differential equations have been proposed and well developed over the past few decades. However, it is quite challenging to use experimental or clinical data to estimate the unknown parameters (both constant and time-varying parameters) in complex nonlinear differential equation models. Therefore, investigators usually fix some parameter values, from the literature or by experience, to obtain only parameter estimates of interest from clinical or experimental data. However, when such prior information is not available, it is desirable to determine all the parameter estimates from data. In this paper we intend to combine the newly developed approaches, a multi-stage smoothing-based (MSSB) method and the spline-enhanced nonlinear least squares (SNLS) approach, to estimate all HIV viral dynamic parameters in a nonlinear differential equation model. In particular, to the best of our knowledge, this is the first attempt to propose a comparatively thorough procedure, accounting for both efficiency and accuracy, to rigorously estimate all key kinetic parameters in a nonlinear differential equation model of HIV dynamics from clinical data. These parameters include the proliferation rate and death rate of uninfected HIV-targeted cells, the average number of virions produced by an infected cell, and the infection rate which is related to the antiviral treatment effect and is time-varying. To validate the estimation methods, we verified the identifiability of the HIV viral dynamic model and performed simulation studies.

description: Temporal network data are increasingly available in various domains, and often represent highly complex systems with intricate structural and temporal evolutions. Due to the difficulty of processing such complex data, it may be useful to coarse grain temporal network data into a numeric trajectory embedded in a low-dimensional space. We refer to such a procedure as temporal network embedding, which is distinct from procedures that aim at embedding individual nodes. Temporal network embedding is a challenging task because we often have access only to discrete time-stamped events between node pairs, and, in general, the events occur with irregular intervals, making the construction of the network at a given time a nontrivial question already. We propose a method to generate trajectories of temporal networks embedded in a low-dimensional space given a sequence of time-stamped events as input. We realize this goal by combining the landmark multidimensional scaling, which is an out-of-sample extension of the well-known multidimensional scaling method, and the framework of tie-decay temporal networks. This combination enables us to obtain a continuous-time trajectory describing the evolution of temporal networks. We then study mathematical properties of the proposed temporal network embedding framework. Finally, we showcase the method with empirical data of social contacts to find temporal organization of contact events and loss of them over a single day and across different days.

description: Transparent conducting oxides (TCOs) play an essential role in modern optoelectronic devices through their combination of electrical conductivity and optical transparency. We review recent progress in our understanding of multi-component TCOs formed from solid-solutions of ZnO, In2O3, Ga2O3 and Al2O3, with a particular emphasis on the contributions of materials modelling, primarily based on Density Functional Theory. In particular, we highlight three major results from our work: (i) the fundamental principles governing the crystal structures of multi-component oxide structures including (In2O3)(ZnO)n, named IZO, and (In2O3)m(Ga2O3)l(ZnO)n, named IGZO; (ii) the relationship between elemental composition and optical and electrical behaviour, including valence band alignments; (iii) the high-performance of amorphous oxide semiconductors. From these advances, the challenge of the rational design of novel electroceramic materials is discussed.

description: Studies of local galaxies suggest that both star-forming and quiescent galaxies formed in an inside-out fashion. Local stellar metallicity encodes past information on the stellar assembly, and it appears to correlate best with the local escape velocity. We present the first study of spatially resolved Lick indices at redshift ~1, using 700 galaxies from the LEGA-C Survey. We show: 1) an empirical correlation between Lick index strenght and escape velocity, a relation that is both global and local 2) despite both inside-out and outside-in formation channels being present, the overall majority of galaxies is consistent with the first formation mechanism.

description: We give a pedagogical introduction to quantum discord. We the discuss the problem of separation of total correlations in a given quantum state into entanglement, dissonance, and classical correlations using the concept of relative entropy as a distance measure of correlations. This allows us to put all correlations on an equal footing. Entanglement and dissonance, whose definition is introduced here, jointly belong to what is known as quantum discord. Our methods are completely applicable for multipartite systems of arbitrary dimensions. We finally show, using relative entropy, how different notions of quantum correlations are related to each other. This gives a single theory that incorporates all correlations, quantum, classical, etc.

description: A polymer cross-linker is a chemical agent that can create covalent bonds between the molecular chains that comprise a polymeric material. Recently, a novel, versatile, bis-diazirine based polymer cross-linker was reported,1 but its cross-linking efficacy is relatively low and can be improved. Moreover, the details of the mechanism of cross-linking has not been reported. In this thesis, we use state-of-art computational chemistry methods to explore how carbenes derived from bis-diazirines engage in cross-linking and identify the factors that affect the cross-linking efficacy. The computational results show that bis-diazirines do not form bis-carbenes in a concerted fashion upon thermal activation. Instead, the carbene centers are generated sequentially. The use of substituents on the carbene center (i.e. p-X-C6H4-C̈-R) and para to the carbene center can significantly influence the electronic state of carbenes, as well as the barrier heights associated with carbene formation and carbene insertion. Therefore, substitution provides a general strategy to control the reactivity of the cross-linker. We also explore how tether units and different ring structures may impact cross-linker performance, and possible carbene side- and self-reactions. To the best of our knowledge, this is the first computational study on this type of polymer cross-linker, and the results provide guidance and insights for improving cross-linking performance systematically. The data obtained were used to propose a next-generation diazirine-based polymer cross-linker.

description: High-fidelity and rapid readout of a qubit state is key to quantum computing and communication, and it is a prerequisite for quantum error correction. We present a readout scheme for superconducting qubits that combines two microwave techniques: applying a shelving technique to the qubit that effectively increases the energy-relaxation time, and a two-tone excitation of the readout resonator to distinguish among qubit populations in higher energy levels. Using a machine-learning algorithm to post-process the two-tone measurement results further improves the qubit-state assignment fidelity. We perform single-shot frequency-multiplexed qubit readout, with a 140ns readout time, and demonstrate 99.5% assignment fidelity for two-state readout and 96.9% for three-state readout - without using a quantum-limited amplifier.

description: Additional file 2: Figure S2.Inflation source during the 2014 unrest of the SPCG from March 2014 to October 2015. Optimal crack parameters are summarized at lower right in the figure. We searched for the best-fit combination of four parameters (Z, L, A, and U), assuming a sill-like source (D = 0°) and L/W = 2. The latitude and longitude of the center of the sill were fixed at 36.645° and 138.538°, respectively, representing the center of Mizugama crater. In this analysis, the smallest misfit (root mean square sum of the difference between the observed and calculated values of each tilt vector, and each uplift at KSYG (44 mm) and KSE (25 mm) measured by GNSS) was calculated by the grid-search method as described in Section “Modeling”. The optimal length (L), width (W), and dislocation (U) were 480 m, 240 m (assumed as half of the horizontal length), and 1.00 m, respectively, which resulted in a calculated volumetric expansion of ~1.2 × 105 m3.

description: Il tema della conoscenza e della consapevolezza del proprio corpo è fortemente sentito alla scuola dell’infanzia in quanto, in questo periodo di crescita, il bambino fonda le basi per la sua conoscenza dello schema corporeo e motorio. Con l’intento di voler proporre un metodo alternativo per raggiungere questo scopo, che non sia di fatto composto da schede e osservazione di figure umane, ma bensì basato sulla didattica attiva, ludica e vissuta, ho voluto condurre la seguente ricerca. Lo scopo è stato quello di verificare se effettivamente delle attività motorie espressive, composte dalla drammatizzazione di svariati animali, che hanno una componente di parallelismo con le nostre parti del corpo, avessero una ricaduta positiva sulle conoscenze del bambino su tre livelli: grafico-pittorico, lessicale e motorio. La ricerca non ha mostrato alcun cambiamento significativo per quanto riguarda i test di disegno di una figura umana e di risposta motoria sulla conoscenza delle possibilità di movimento del nostro corpo. Tuttavia vi è stato un miglioramento per quanto riguarda il livello lessicale, da cui si possono estrapolare elementi riconducibili alla sperimentazione fatta in sezione.

description: We derive a single field slow-roll inflaton potential in three intersecting $D7$ branes configuration under type IIB/F-theory compactification. Among three resulting Kähler moduli corresponding to three orthogonal directions, two are stabilized via perturbative corrections in Kähler potential arising from large volume scenario ($α'^3$) and four graviton scattering amplitude upto one loop level and the remaining Kähler modulus is stabilized by KKLT-type non-perturbative correction in superpotential. The symmetric combination of two canonically normalized and perturbatively stabilized Kähler moduli gives the inflaton field and the anti-symmetric combination manifests as an auxiliary field.

Comportamentos de envolvimento observáveis e inobserváveis de estudantes universitários de Climatologia
Creators: name: Seixas, Teresa M.

Publisher: name: Zenodo
Year: 2020

description: Este estudo teve como objetivo investigar os comportamentos de envolvimento observáveis e inobserváveis de estudantes universitários e a sua possível relação com o desempenho académico. O estudo foi realizado no âmbito da unidade curricular (UC) de Climatologia, do primeiro ciclo de licenciatura em Ciências e Tecnologia do Ambiente, lecionada no segundo semestre do segundo ano letivo de 2018/19, no Departamento de Física e Astronomia, da Faculdade de Ciências da Universidade do Porto (UP). Os dados foram obtidos através de um questionário online, disponibilizado na plataforma Moodle da UP e intitulado “Comportamentos Observáveis e Inobserváveis do Envolvimento do Estudante (COIEE)”, numa escala de Likert de cinco pontos, centrada em zero. O questionário COIEE era composto por vinte questões de escolha múltipla, divididas em duas subescalas 1. Comportamentos de Envolvimento Observáveis; e 2. Comportamentos de Envolvimento Inobserváveis. Este questionário foi validado através do cálculo do coeficiente alfa de Cronbach. Os dados obtidos mostram que os comportamentos de envolvimento inobserváveis são mais frequentes do que os observáveis. Isso pode refletir as dificuldades que a maioria dos estudantes enfrentam na compreensão dos conteúdos curriculares, o que provavelmente desencadeia a sua introspeção (inobservável), em detrimento do seu comportamento de envolvimento observável. É de referir que a maior parte do programa da UC de Climatologia consistia em conteúdos novos, para os quais os estudantes, geralmente, não têm conhecimento ou experiência anterior, podendo, por isso, constituir um grande desafio para os estudantes o fornecimento de feedback observável e regular durante uma aula teórico-prática de resolução e discussão de problemas. Além disto, existe uma tendência comum para os estudantes do primeiro ciclo prepararem as aulas com antecedência e envolverem-se menos, tanto de forma observável quanto inobservável, nas atividades em sala de aula. Não foi encontrada uma correlação significativa entre as notas finais dos estudantes e as suas respostas ao questionário COIEE, o que exclui qualquer relação possível entre o desempenho académico dos estudantes e os seus comportamentos de envolvimento em aulas de resolução de problemas.

The provisions of the theory of gearing are applied to obtain the coordinates of the points of the line of engagement and the profile of EC-engagement. The transmission operation was simulated to analyze the geometric-kinematic characteristics of the gearing. Investigated the forces in the mesh, sliding speed, power and friction forces in the mesh. The dependences of the work of friction forces on the diameter and eccentricities of eccentrics are obtained. Developed the appropriate software.

description: The Fermi liquid approach is applied to the problem of spontaneous violation of the four-fold rotational point-group symmetry ($C_4$) in strongly correlated two-dimensional electronic systems on a square lattice. The symmetry breaking is traced to the existence of a topological phase transition. This continuous transition is triggered when the Fermi line, driven by the quasiparticle interactions, reaches the van Hove saddle points, where the group velocity vanishes and the density of states becomes singular. An unconventional Fermi liquid emerges beyond the implicated quantum critical point.

description: Chemical compositions of stars provide us with unique information about their nucleosynthesis processes and the chemical enrichment of the Galaxy. Elements heavier than iron cannot be produced by nuclear fusion and require capturing neutrons by lighter elements. However, the conditions and environment needed for such processes are still relatively uncertain. While it is well established that asymptotic giant branch stars play an important role in the production of s-process chemical elements, recent studies show that their contribution was underestimated. As dwarf stars have a very long, relatively stable lives and do not show any substantial stellar evolution; their surface abundances are very helpful for studying the environment and time in which they were formed.

Our aim was to determine abundance patterns of neutron-capture elements and probe the evolution of the Milky Way stellar disc. For this purpose we used spectra obtained with a Vilnius University Echelle Spectrograph and 1.65 m telescope for a sample of almost 300 F and G spectral type bright (V < 8 mag) dwarf stars (logg > 3.5) in two nearby fields towards the north celestial pole direction, with metallicities between -0.7 < [Fe/H] < +0.5. The method used for the analysis of chemical abundances is based on the spectral synthesis using the code TurboSpectrum combined with the MARCS stellar atmospheres models. We provide the chemical composition and time evolution for Sr II; Y II; Zr I; Zr II; Ba II; La II; Ce II; Nd II; Pr II; Sm II; and Eu II at different mean Galactocentric distances.

For majority of the stars investigated in this work, it is the first time that abundances of neutron-capture elements were determined. The investigated stars were used to trace how the s-process was influencing the production of n-capture elements during the evolution of the Galactic thin disc.
