description: Classical optimizers play a crucial role in determining the accuracy and convergence of variational quantum algorithms. In literature, many optimizers, each having its own architecture, have been employed expediently for different applications. In this work, we consider a few popular optimizers and assess their performance in variational quantum algorithms for applications in quantum chemistry in a realistic noisy setting. We benchmark the optimizers with critical analysis based on quantum simulations of simple molecules, such as Hydrogen, Lithium Hydride, Beryllium Hydride, water, and Hydrogen Fluoride. The errors in the ground-state energy, dissociation energy, and dipole moment are the parameters used as yardsticks. All the simulations were carried out with an ideal quantum circuit simulator, a noisy quantum circuit simulator, and a noisy simulator with noise embedded from the IBM Cairo quantum device to understand the performance of the classical optimizers in ideal and realistic quantum environments. We used the standard unitary coupled cluster (UCC) ansatz for simulations, and the number of qubits varied from two, starting from the Hydrogen molecule to ten qubits, in Hydrogen Fluoride. Based on the performance of these optimizers in the ideal quantum circuits, the conjugate gradient (CG), limited-memory Broyden-Fletcher-Goldfarb-Shanno bound (L_BFGS)B), and sequential least squares programming (SLSQP) optimizers are found to be the best-performing gradient-based optimizers. While constrained optimization by linear approximation (COBYLA) and POWELL perform most efficiently among the gradient-free methods. However, in noisy quantum circuit conditions, Simultaneous Perturbation Stochastic Approximation (SPSA), POWELL, and COBYLA are among the best-performing optimizers.

description: In order to find the spectrum associated with the one-dimensional Schröodinger equation, we discuss the Lagrange Mesh method (LMM) and its numerical implementation for bound states. After presenting a general overview of the theory behind the LMM, we introduce the LagrangeMesh package: the numerical implementation of the LMM in Mathematica. Using few lines of code, the package enables a quick home-computer computation of the spectrum and provides a practical tool to study a large class of systems in quantum mechanics. The main properties of the package are (i) the input is basically the potential function and the interval on which is defined; and (ii) the accuracy in calculations and final results is controllable by the user. As illustration, a highly accurate spectrum of some relevant quantum systems is obtained by employing the commands that the package offers. In fact, the present work can be regarded as a user guide based on worked examples.

description: We use Lyapunov-like functions and convex optimization to propagate uncertainty in the initial condition of nonlinear systems governed by ordinary differential equations. We consider the full nonlinear dynamics without approximation, producing rigorous bounds on the expected future value of a quantity of interest even when only limited statistics of the initial condition (e.g., mean and variance) are known. For dynamical systems evolving in compact sets, the best upper (lower) bound coincides with the largest (smallest) expectation among all initial state distributions consistent with the known statistics. For systems governed by polynomial equations and polynomial quantities of interest, one-sided estimates on the optimal bounds can be computed using tools from polynomial optimization and semidefinite programming. Moreover, these numerical bounds provably converge to the optimal ones in the compact case. We illustrate the approach on a van der Pol oscillator and on the Lorenz system in the chaotic regime.

description: Abstract – Since the 1990s, emotions are no longer regarded as a disturbing factor with respect to learning mechanisms, but are conceptualized as a central dimension of any complex cognitive behavior. Moreover, their status as a scientific construct is affirmed, which can be studied like other individual variables, e.g. attention or memory. However, two issues remain open: the first concerns specific training on how to teach and assess emotional and social competences in children and young people. The second issue concerns the most effective ways of incorporating emotional competences into teacher planning. In this article, an exploratory study is presented on a sample of teachers belonging to different school orders: the aim is to investigate how emotions and emotional competences enter the teacher's professional profile and his or her educational planning in the classroom. Riassunto – A partire dagli anni Novanta, le emozioni non sono più considerate un fattore di disturbo rispetto ai meccanismi dell’apprendimento, ma vengono concettualizzate come una dimensione centrale di qualsiasi condotta cognitiva complessa. Inoltre, si afferma il loro status di costrutto scientifico, che può essere studiato come altre variabili individuali, ad esempio l’attenzione o la memoria. Tuttavia, rimangono aperte due questioni: la prima riguarda la formazione specifica su come insegnare e valutare le competenze emotive e sociali nei bambini e nei ragazzi. Il secondo aspetto riguarda le modalità più efficaci per inserire le competenze emotive nell’azione progettuale dell’insegnante. Nel presente articolo, viene presentato uno studio esplorativo su un campione di insegnanti appartenenti ai diversi ordini di scuola: l’obiettivo è quello di indagare come le emozioni e le competenze emotive entrano nel profilo professionale del docente e nella sua progettualità didattica in classe. Keywords – emotions, emotional competence, school, teachers, professional role Parole-chiave – emozioni, competenze emotive, scuola, insegnanti, ruolo professionale

description: We give a general description of the moment cone associated with an arbitrary finite-dimensional unitary representation of a compact, connected Lie group in terms of finitely many linear inequalities. Our method is based on combining differential-geometric arguments with a variant of Ressayre's notion of a dominant pair. As applications, we obtain generalizations of Horn's inequalities to arbitrary representations, new inequalities for the one-body quantum marginal problem in physics, which concerns the asymptotic support of the Kronecker coefficients of the symmetric group, and a geometric interpretation of the Howe-Lee-Tan-Willenbring invariants for the tensor product algebra.

description: We initiate the study of the internal structure of C*-algebras associated to a left cancellative semigroup in which any two principal right ideals are either disjoint or intersect in another principal right ideal; these are variously called right LCM semigroups or semigroups that satisfy Clifford's condition. Our main findings are results about uniqueness of the full semigroup C*-algebra. We build our analysis upon a rich interaction between the group of units of the semigroup and the family of constructible right ideals. As an application we identify algebraic conditions on S under which C*(S) is purely infinite and simple.

description: A toy-model with $SU(2)_{\rm TC}$ dynamics confined at high scales $Λ_{\rm TC}\gg 100$ GeV enables to construct Dirac UV completion from the original chiral multiplets predicting a vector-like nature of their weak interactions consistent with electroweak precision tests. In this work, we investigate a potential of the lightest scalar baryon-like (T-baryon) state $B^0=UD$ with mass $m_B\gtrsim 1$ TeV predicted by the simplest two-flavor vector-like confinement model as a Dark Matter (DM) candidate. We show that two different scenarios with the T-baryon relic abundance formation before and after the electroweak (EW) phase transition epoch lead to symmetric (or mixed) and asymmetric DM, respectively. Such a DM candidate evades existing direct DM detection constraints since its vector coupling to $Z$ boson absents at tree level, while one-loop gauge boson mediated contribution is shown to be vanishingly small close to the threshold. The dominating spin-independent (SI) T-baryon--nucleon scattering goes via tree-level Higgs boson exchange in the $t$-channel. The corresponding bound on the effective T-baryon--Higgs coupling has been extracted from the recent LUX data and turns out to be consistent with naive expectations from the light technipion case $m_{\tilde π}\ll Λ_{\rm TC}$. The latter provides the most stringent phenomenological constraint on strongly-coupled $SU(2)_{\rm TC}$ dynamics so far. Future prospects for direct and indirect scalar T-baryon DM searches in astrophysics as well as in collider measurements have been discussed.

description: Recent approximations to backpropagation (BP) have mitigated many of BP's computational inefficiencies and incompatibilities with biology, but important limitations still remain. Moreover, the approximations significantly decrease accuracy in benchmarks, suggesting that an entirely different approach may be more fruitful. Here, grounded on recent theory for Hebbian learning in soft winner-take-all networks, we present multilayer SoftHebb, i.e. an algorithm that trains deep neural networks, without any feedback, target, or error signals. As a result, it achieves efficiency by avoiding weight transport, non-local plasticity, time-locking of layer updates, iterative equilibria, and (self-) supervisory or other feedback signals -- which were necessary in other approaches. Its increased efficiency and biological compatibility do not trade off accuracy compared to state-of-the-art bio-plausible learning, but rather improve it. With up to five hidden layers and an added linear classifier, accuracies on MNIST, CIFAR-10, STL-10, and ImageNet, respectively reach 99.4%, 80.3%, 76.2%, and 27.3%. In conclusion, SoftHebb shows with a radically different approach from BP that Deep Learning over few layers may be plausible in the brain and increases the accuracy of bio-plausible machine learning.

description: We calculate the ${\cal O}(α_s)$ radiative corrections to the spin dependent differential decay rates of the process $t\rightarrow b+W^+$. These are needed to study the angular distribution of the energy of hadrons produced in polarized top quark decays at next-to-leading order (NLO). In our previous work, we studied the angular distribution of the scaled-energy of bottom-flavored hadrons (B) from polarized top quark decays, using a specific helicity coordinate system where the top quark spin was measured relative to the bottom momentum (system~1). Here, we study the angular distribution of the energy spectrum of B-hadron in a different helicity system, where the top spin is specified relative to the W-momentum (system~2). These energy distributions are governed by the polarized and unpolarized rate functions which are related to the density matrix elements of the decay $t\rightarrow W^++b$. Through this paper, we present our predictions of the B-hadron spectrum in the polarized and unpolarized top decay and shall compare the polarized results in two different helicity systems. These predictions can be used to determine the polarization states of top quarks and also provide direct access to the B-hadron fragmentation functions (FFs) and allow us to deepen our knowledge of the hadroniazation process.

description: We introduce two tools, dynamical thickening and flow selectors, to overcome the infamous discontinuity of the gradient flow endpoint map near non-degenerate critical points. More precisely, we interpret the stable fibrations of certain Conley pairs $(N,L)$, established in [2,3], as a dynamical thickening of the stable manifold. As a first application and to illustrate efficiency of the concept we reprove a fundamental theorem of classical Morse theory, Milnor's homotopical cell attachment theorem [1]. Dynamical thickening leads to a conceptually simple and short proof.

OPE of the energy-momentum tensor correlator and the gluon condensate operator in massless QCD to three-loop order

description: The correlator of two gluonic operators plays an important role for example in transport properties of a Quark Gluon Plasma (QGP) or in sum rules for glueballs. In [1] an operator product expansion (OPE) at zero temperature was performed for the correlators of two scalar operators $O_1=-\frac{1}{4} G^{μν}G_{μν}$ and two QCD energy-momentum tensors $T^{μν}$. There we presented analytical two-loop results for the Wilson coefficient $C_1$ in front of the gluon condensate operator $O_1$. In this paper these results are extended to three-loop order. The three-loop Wilson coefficient $C_0$ in front of the unity operator $O_0=1$ was already presented in [1] for the $T^{μν}$-correlator. For the $O_1$-correlator the coefficient $C_0$ is known to four loop order from [2]. For the correlator of two pseudoscalar operators $\tilde{O}_1=\varepsilon_{μνρσ} G^{μν} G^{ρσ}$ both coefficients $C_0$ and $C_1$ were computed in [3] to three-loop order. At zero temperature $C_0$ and $C_1$ are the leading Wilson coefficients in massless QCD.

description: We present a model to explain the Standard Model flavor hierarchy. Our model is based on explicit smooth confinement (namely confinement without chiral symmetry breaking in a supersymmetric gauge theory) at an intermediate energy scale, before the electroweak symmetry breaking by the Higgs condensation at lower energy. In our context, the smooth confinement preserves the SU(3) and the chiral SU(2)$_L\times$ U(1)$_Y$ symmetry in a supersymmetric Standard Model, while this internal symmetry becomes dynamically gauged in the end. In contrast to Razamat-Tong's symmetric mass generation model also preserving the $G_{\rm SM} \equiv$ SU(3)$_C\times$ SU(2)$_L\times$ U(1)$_Y$ internal symmetry, our model introduces different matter contents with a different kind of superpotential deformation irrelevant at UV, which further induces Yukawa-Higgs terms marginal at IR, breaking the $G_{\rm SM}$ down to SU(3)$_C$ and the electromagnetic U(1)$_{\rm EM}$ only when Higgs condenses. In our model, the IR fermions in the first and second families are composite of UV fields, while the third family elementary fermions match between UV and IR. The smallness of the first and second family fermion masses is explained by the exponential hierarchy between the cutoff scale and the smooth confinement scale via dimensional transmutation. As a result, our UV Lagrangian only contains the natural parameters close to the order one.

description: Abstract – This paper is a reflection on the potential of teaching methodologies that focus on the phenomenon of dissonance or cognitive conflict. In a multicultural and increasingly polarized society, the capacity to question one’s own beliefs and behaviors is certainly one of the skills that the educational system should promote, and the development of this competence is closely related to the effective control of the experience of dissonance originated by new information. Starting from a brief reconstruction of the pedagogical and psychological literature on the subject, I will try to analyze the complexity of the phenomenon of cognitive dissonance by proposing an explanation of the contradictory results of empirical research, identifying as the main problematic nodes the emotional regulation of conflict and the role of the teacher as a facilitator of the process of conceptual change. Riassunto – Questo lavoro costituisce una riflessione sulle potenzialità delle metodologie didattiche che pongono al centro il fenomeno della dissonanza o conflitto cognitivo. In una società multiculturale e sempre più polarizzata, la capacità di mettere in discussione le proprie credenze e i propri comportamenti è sicuramente una delle competenze che il sistema educativo dovrebbe promuovere, e lo sviluppo di tale competenza è strettamente legato alla gestione efficace dell’esperienza della dissonanza originata da nuove informazioni. Partendo da una breve ricostruzione della letteratura pedagogica e psicologica sul tema, si cercherà di analizzare la complessità del fenomeno della dissonanza cognitiva proponendo una spiegazione dei risultati contraddittori della ricerca empirica, individuando come principali nodi problematici la gestione emotiva del conflitto e il ruolo dell’insegnante in quanto facilitatore del processo di cambiamento concettuale.

title: Mechanisms of rainfall in Middle America
Creators: name: Franco Diaz, Armenia
Publisher: name: University of Reading
Year: 2021

description: Seasonal rainfall over Middle America is crucial for human and wildlife welfare, agri�culture, industry, and hydroelectric infrastructure. The biophysical and social conditions in Middle America make this region particularly vulnerable to rainfall variability. Extreme events, such as tropical cyclones (TCs), can exacerbate seasonal variability of regional rainfall. This thesis aims to understand the causes of interannual variability of seasonal rainfall in Middle America, the TC contribution to the regional hydrological cycle, and the causes of interannual variability of seasonal TC-related rainfall. Regions of coherent interannual variability of seasonal rainfall are identified using the objective Empirical Orthogonal Teleconnections (EOT) technique. El Ni˜no-Southern Oscillation (ENSO) is responsible for the largest fraction of interannual variability of sea�sonal rainfall, with canonical ENSO events driving more variability than ENSO Modoki. The Atlantic Meridional Mode (AMM) and local land-atmosphere processes are secondary drivers of interannual rainfall variability. TCs are important rainfall sources in Middle America during boreal summer, partic�ularly on the Gulf coastal plain, the Mexican western coast and the southernmost states of Mexico. TCs contribute ≈ 10–30% of monthly accumulated rainfall (June-October) in those regions, with the most substantial contribution in Baja California Peninsula of up to 90% in September. TCs contribute 40–60% of extreme daily rainfall over Middle American coasts. TCs are a significant moisture source for the regional water budget; TC vertically integrated moisture flux (VIMF) convergence can turn regions of weak VIMF divergence by the mean circulation into regions of weak VIMF convergence. Interannual variability of TC-related rainfall is mainly driven by ENSO, through variations in East Pacific and North Atlantic TC activity. The AMM is the secondary driver, through changes in North Atlantic TC activity. Changes in location and strength of the North Atlantic Subtropical High and the Caribbean Low-Level Jet are important circulation features that influence TC rainfall variability.

description: The Hamiltonian constraint Hc = NH = 0, defines a diffeomorphic structure on spatial manifolds by the lapse function N in general theory of relativity. However, it is not manifest in Lanczos-Lovelock gravity, since the expression for velocity in terms of the momentum is multivalued. Thus the Hamiltonian is a branch function of momentum. Here we propose an extended theory of Lanczos-Lovelock gravity to construct a unique Hamiltonian in its minisuperspace version, which results in manifest diffeomorphic invariance and canonical quantization.

description: Powered by acoustics, existing therapeutic and diagnostic procedures will become less invasive and new methods will become available that have never been available before. Acoustically driven microrobot navigation based on microbubbles is a promising approach for targeted drug delivery. Previous studies have used acoustic techniques to manipulate microbubbles in vitro and in vivo for the delivery of drugs using minimally invasive procedures. Even though many advanced capabilities and sophisticated control have been achieved for acoustically powered microrobots, there remain many challenges that remain to be solved. In order to develop the next generation of intelligent micro/nanorobots, it is highly desirable to conduct accurate identification of the micro-nanorobots and to control their dynamic motion autonomously. Here we use reinforcement learning control strategies to learn the microrobot dynamics and manipulate them through acoustic forces. The result demonstrated for the first time autonomous acoustic navigation of microbubbles in a microfluidic environment. Taking advantage of the benefit of the second radiation force, microbubbles swarm to form a large swarm, which is then driven along the desired trajectory. More than 100 thousand images were used for the training to study the unexpected dynamics of microbubbles. As a result of this work, the microrobots are validated to be controlled, illustrating a good level of robustness and providing computational intelligence to the microrobots, which enables them to navigate independently in an unstructured environment without requiring outside assistance.

description: In the collider phenomenology of extensions of the Standard Model with partner particles, cascade decays occur generically, and they can be challenging to discover when the spectrum of new particles is compressed and the signal cross section is low. Achieving discovery-level significance and measuring the properties of the new particles appearing as intermediate states in the cascade decays is a longstanding problem, with analysis techniques for some decay topologies already optimized. We focus our attention on a benchmark decay topology with four final state particles where there is room for improvement, and where multidimensional analysis techniques have been shown to be effective in the past. Using machine learning techniques, we identify the optimal kinematic observables for discovery, spin determination and mass measurement. In agreement with past work, we confirm that the kinematic observable $Δ_4$ is highly effective. We quantify the achievable accuracy for spin determination and for the precision for mass measurements as a function of the signal size.

description: The Berry curvature provides a powerful tool to unify several branches of science through their geometrical aspect: topology, energy bands, spin and vector fields. While quantum defects -- phase vortices and skyrmions -- have been in the spotlight, as rotational entities in condensates, superfluids and optics, their dynamics in multi-component fields remain little explored. Here we use two-component microcavity polaritons to imprint a dynamical pseudospin texture in the form of a double full Bloch beam, a conformal continuous vortex beyond unitary skyrmions. The Berry curvature plays a key role to link various quantum spaces available to describe such textures. It explains for instance the ultrafast spiraling in real space of two singular vortex cores, providing in particular a simple expression -- also involving the complex Rabi frequency -- for their intricate velocity. Such Berry connections open new perspectives for understanding and controlling highly-structured quantum objects, including strongly asymmetric cases or even higher multi-component fields.

description: Introduction : Les ergothérapeutes peuvent intervenir dans différents contextes qui offrent des services dans le domaine de la santé mentale, notamment dans celui des soins aigus psychiatriques en milieu hospitalier. Dans ce contexte, les mesures de contention, dont l’isolement, sont utilisées comme moyen de gestion de la violence pour les personnes présentant des risques de comportements auto- ou hétéro-agressifs. En Suisse romande, les ergothérapeutes qui travaillent dans ce contexte interviennent auprès des personnes placées en isolement. Il existe cependant peu de littérature sur le rôle spécifique de l’ergothérapeute dans ce contexte. But : L’objectif de ce travail est d’explorer le rôle de l’ergothérapeute auprès de la clientèle adulte placée en isolement. Méthode : La méthodologie choisie pour ce travail est la revue de la portée, articulée selon la structure proposée par Arksey & O’Malley (2005). Cette revue explore le rôle des ergothérapeutes auprès de la clientèle en isolement en prenant en compte des articles à la fois dans le contexte de l’isolement, mais également dans le contexte plus global des soins aigus psychiatriques. Les données ont ensuite été traitées par le biais d’une analyse thématique selon la marche à suivre proposée par Braun & Clarke (2006). Résultats : Dix articles ont été inclus, cinq concernant la pratique en isolement et cinq concernant la pratique en soins aigus psychiatriques. L’analyse thématique a permis d’identifier trois thèmes principaux quant au rôle de l’ergothérapeute : les objectifs et résultats des interventions, les caractéristiques des interventions et finalement, les barrières et facilitateurs. Conclusion : Cette revue de la portée met en avant différents éléments qui permettent de mieux appréhender les différents buts, méthodes et enjeux autour de la pratique des ergothérapeutes auprès de la clientèle en isolement. Les résultats indiquent un manque important de littérature spécifique à cette pratique. [Résumé de l'auteure].

description: We provide the reformulations of Yang-Mills theories in terms of gauge invariant metric-like variables in three and four dimensions. The reformulations are used to analyze the dimension two gluon condensate and give gauge invariant descriptions of gluon polarization. In three dimensions, we obtain a non-zero dimension two gluon condensate by one loop computation, whose value is similar to the square of photon mass in the Schwinger model. In four dimensions, we obtain a Lagrangian with the dual property, which shares the similar but different property with the dual superconductor scenario. We also make discussions on the effectiveness of one loop approximation.

description: Geological process models simulate a range of dynamic processes to evolve a base topography into a final 2D cross-section or 3D geological scenario. In principle, process parameters may be updated to better align with observed geophysical or geological data; however, many realisations of process models that embody different conceptual models may provide similar consistency with observed data, and finding all such realisations may be infeasible due to the computational demands of the task. Alternatively, geophysical probabilistic tomographic methods may be used to estimate the family of models of a target subsurface structure that are consistent both with information obtained from previous experiments and with new data (the Bayesian posterior distribution). However, this family seldom embodies geologically reasonable images. We show that the posterior distribution of tomographic images can be enhanced by injecting geological prior information into Bayesian inference, and we can do this near-instantaneously by trained MDNs. We invoke two geological concepts as geological prior information: a braided river system, and a set of marine parasequences, each parameterised by a GAN. Data from a target structure can then be used to infer the image parameter values using either geological concept using MDNs. Our MDN solutions closely resemble those found using expensive McMC methods, and while the use of incorrect geological conceptual models provides less accurate results the mean structures still approximate the target. We then show that a classification network can infer the correct geological conceptual model. Thus, imposing even incorrect geological prior information may improve geophysical tomographic images compared to those obtained without geological prior information, and in principle geological conceptual models can be inferred directly from geophysical travel time data.
Fermat's Cubic, Klein's Quartic and Rigid Complex Manifolds of Kodaira Dimension One

description: For each $n \geq 3$ we provide an $n$-dimensional rigid compact complex manifold of Kodaira dimension $1$. First we constructed a series of singular quotients of products of $(n-1)$ Fermat curves with the Klein quartic, which are rigid. Then using toric geometry a suitable resolution of singularities is constructed and the deformation theories of the singular model and of the resolutions are compared, showing the rigidity of the resolutions.

description: The wave-particle duality dates back to Einstein's explanation of the photoelectric effect through quanta of light and de Broglie's hypothesis of matter waves. Quantum mechanics uses an abstract description for the behavior of physical systems such as photons, electrons, or atoms. Whether quantum predictions for single systems in an interferometric experiment allow an intuitive understanding in terms of the particle or wave picture, depends on the specific configuration which is being used. In principle, this leaves open the possibility that quantum systems always either behave definitely as a particle or definitely as a wave in every experimental run by a priori adapting to the specific experimental situation. This is precisely what is tried to be excluded by delayed-choice experiments, in which the observer chooses to reveal the particle or wave character -- or even a continuous transformation between the two -- of a quantum system at a late stage of the experiment. We review the history of delayed-choice gedanken experiments, which can be traced back to the early days of quantum mechanics. Then we discuss their experimental realizations, in particular Wheeler's delayed choice in interferometric setups as well as delayed-choice quantum erasure and entanglement swapping. The latter is particularly interesting, because it elevates the wave-particle duality of a single quantum system to an entanglement-separability duality of multiple systems.

description: N-type doping of high-resistance wide bandgap semiconductors, wurtzite high-Mg-content MgxZn1-xO for instance, has always been a fundamental application-motivated research issue. Herein, we report a solution to enhancing the conductivity of high-resistance Mg0.51Zn0.49O active components, which has been reliably achieved by fluorine doping via radio-frequency plasma assisted molecular beam epitaxial growth. Fluorine dopants were demonstrated to be effective donors in Mg0.51Zn0.49O single crystal film having a solar-blind 4.43 eV bandgap, with an average concentration of 1.0E19 F/cm3.The dramatically increased carrier concentration (2.85E17 cm-3 vs ~1014 cm-3) and decreased resistivity (129 ohm.cm vs ~10E6 ohm cm) indicate that the electrical properties of semi-insulating Mg0.51Zn0.49O film can be delicately regulated by F doping. Interestingly, two donor levels (17 meV and 74 meV) associated with F were revealed by temperature-dependent Hall measurements. A Schottky type metal-semiconductor-metal ultraviolet photodetector manifests a remarkably enhanced photocurrent, two orders of magnitude higher than that of the undoped counterpart. The responsivity is greatly enhanced from 0.34 mA/W to 52 mA/W under 10 V bias. The detectivity increases from 1.89E9 cm Hz1/2/W to 3.58eE10 cm Hz1/2/W under 10 V bias at room temperature.These results exhibit F doping serves as a promising pathway for improving the performance of high-Mg-content MgxZn1-xO-based devices.

description: In this contribution, Daniela Sacco offers us a reflection on the possibility of considering the ‘atlas form’, deduced from the thought of Aby Warburg, as a model for investigating the methodology of twentieth-century theatrical historiography, and in particular in the pioneering studies opened by Ludovico Zorzi and Fabrizio Cruciani. Two authors who stand in continuity and significantly share with Warburg an interest in the study of Renaissance culture.
