description: This paper presents a novel algorithm for the continuous control of dynamical systems that combines Trajectory Optimization (TO) and Reinforcement Learning (RL) in a single framework. The motivations behind this algorithm are the two main limitations of TO and RL when applied to continuous nonlinear systems to minimize a non-convex cost function. Specifically, TO can get stuck in poor local minima when the search is not initialized close to a "good" minimum. On the other hand, when dealing with continuous state and control spaces, the RL training process may be excessively long and strongly dependent on the exploration strategy. Thus, our algorithm learns a "good" control policy via TO-guided RL policy search that, when used as initial guess provider for TO, makes the trajectory optimization process less prone to converge to poor local optima. Our method is validated on several reaching problems featuring non-convex obstacle avoidance with different dynamical systems, including a car model with 6D state, and a 3-joint planar manipulator. Our results show the great capabilities of CACTO in escaping local minima, while being more computationally efficient than the Deep Deterministic Policy Gradient (DDPG) and Proximal Policy Optimization (PPO) RL algorithms.

On the Nature of the Purported Common Proper Motion Companions to the Exoplanet Host Star 51 Peg

description: Greaves (2006) proposed that three red, high proper motion stars within 10 degrees of 51 Peg (NLTT 54007, 54064, & 55547) are co-moving companions to this famous exoplanet host star. While the stars clearly have proper motions similar to 51 Peg, the inferred kinematic parallaxes for these stars produce extremely inconsistent color-magnitude positions 2 to 4 magnitudes below the main sequence. All three stars are likely to be background stars unrelated to 51 Peg.

Magnetic interaction at an interface between manganite and other transition metal oxides
Creators: name: Okamoto, Satoshi

Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: A general consideration is presented for the magnetic interaction at an interface between a perovskite manganite and other transition metal oxides. The latter is specified by the electron number $n$ in the $d_{3z^2-r^2}$ level as $(d_{3z^2-r^2})^n$. Based on the molecular orbitals formed at the interface and the generalized Hund's rule, the sign of the magnetic interaction is rather uniquely determined. The exception is when the $d_{3z^2-r^2}$ orbital is stabilized in the interfacial manganite layer neighboring to a $(d_{3z^2-r^2})^1$ or $(d_{3z^2-r^2})^2$ system. In this case, the magnetic interaction is sensitive to the occupancy of the Mn $d_{3z^2-r2}$ orbital. It is also shown that the magnetic interaction between the interfacial Mn layer and the bulk region can be changed. Manganite-based heterostructures thus show a rich magnetic behavior. We also present how to generalize the argument including $t_{2g}$ orbitals.

Mass of compact stars in f(T) gravity

description: The mass of compact objects in General Relativity (GR), which as is well known, is obtained via the Tolman - Oppenheimer - Volkov (TOV) equations, is a well defined quantity. However, in alternative gravity, this is not in general the case. In the particular case of $f(T)$ gravity, where $T$ is the scalar torsion, some authors consider that this is still an open question, since it is not guaranteed that the same equation used in TOV GR holds. In this paper we consider such an important issue and compare different ways to calculate the mass of compact objects in $f(T)$ gravity. In particular, we argue that one of them, the asymptotic mass, may be the most appropriate way to calculate mass in this theory. We adopt realistic equations of state in all the models presented in this article.

description: Space-resolved X-ray diffraction measurements performed on gradient-etched CuInGaSe2 (CIGS) solar cells provide information about stress and texture depth profiles in the absorber layer. An important parameter for CIGS layer growth dynamics, the absorber thickness-dependent stress in the molybdenum back contact is analyzed. Texturing of grains and quality of the polycrystalline absorber layer are correlated with the intentional composition gradients (band gap grading). Band gap gradient is determined by space-resolved photoluminescence measurements and correlated with composition and strain profiles.

description: In this paper, we perform the Tsallis Blast-Wave analysis on the transverse momentum spectra of identified hadrons produced in a wide range of collision systems at the Large Hadron Collider (LHC) including pp, pPb, XeXe and PbPb collisions. The kinetic freeze-out properties are investigated across these systems varying with the event multiplicity. We find that the extracted kinetic freeze-out temperature, radial flow velocity and the non-extensive parameter exhibit a universal scaling behavior for these systems with very different geometric size, especially when the independent baryon Tsallis non-extensive parameter is considered. This universality may indicate the existence of a unified partonic evolution stage in different collision systems at the LHC energies.

description: In the paper the novel soft magnetic composite system is investigated. A ferrofluid emulsion studied demonstrates the strong magnetic properties which are atypical for commonly known emulsions. Interaction of ferrofluid emulsions with a magnetic field is considered. Structural transformations in these media, such as deformation of emulsion microdroplets and emulsion inversion, are studied. The changes in the relative permeability of emulsion associated with structural transformations are investigated. The theory of the observed phenomena is developed, and the feasibility of effectively controlling the magnetic properties of ferrofluid emulsions by applying a magnetic field is demonstrated.

Parametrization of light nuclei quasiparticle energy shifts and composition of warm and dense nuclear matter
Creators: name: Röpke, G.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Nuclear Theory (nucl-th)

description: Correlations and the formation of bound states (nuclei) are essential for the properties of nuclear matter in equilibrium as well as in nonequilibrium. In a quantum statistical approach, quasiparticle energies are obtained for the light elements that reflect the influence of the medium. We present analytical fits for the quasiparticle energy shifts of light nuclei that can be used in various applications. This is a prerequisite for the investigation of warm and dense matter that reproduces the nuclear statistical equilibrium and virial expansions in the low-density limit as well as relativistic mean field and Brueckner Hartree-Fock approaches near saturation density.

description: Quantum thermodynamics explores novel thermodynamic phenomena that emerge when interactions between macroscopic systems and microscopic quantum ones go into action. Among various issues, quantum heat engines, in particular, have attracted much attention as a critical step in theoretical formulation of quantum thermodynamics and investigation of efficient use of heat by means of quantum resources. In the present paper, we focus on heat absorption and emission processes as well as work extraction processes of a quantum Otto cycle. We describe the former as non-Markovian dynamics, and thereby find that the interaction energy between a macroscopic heat bath and a microscopic qubit is not negligible. Specifically, we reveal that the interaction energy is divided into the system and the bath in a region of the short interaction time and remains negative in the region of the long interaction time. In addition, a counterintuitive energy flow from the system and the interaction energy to the hot bath occurs in another region of the short interaction time. We quantify these effects by defining an index of non-Markovianity in terms of the interaction energy. With this behavior of the interaction energy, we show that a non-Markovian quantum Otto cycle can switch functions such as an engine as well as a heater or a heat pump by controlling the interaction time with the heat bath. In particular, the qubit itself loses its energy if we shorten the interaction time, and in this sense, the qubit is cooled through the cycle. This property has a possibility of being utilized for cooling the qubits in quantum computing. We also describe the work extraction from the microscopic system to a macroscopic system like us humans as an indirect measurement process by introducing a work storage as a new reservoir.

title: Searching in REST service catalogues with OpenAPI descriptions

Creators: name: Στεργιου Ιωαννα-Μαρια
Publisher: name: Technical University of Crete

description: This work presents OpenPI QL, a query language for querying OpenAPI service descriptions. The basic idea behind OpenAPI QL approach is that the OpenAPI document is a description of a REST request with the corresponding responses. The request that is sent from client to the server, and the responses returned back to the client, are actions that OpenAPI describes thoroughly. An important factor of this work is the capability of determining whether data are usable for being searched. Equally important is the handling of data complexity. OpenAPI QL is modeled to deal with JSON files, which are semi-structured data. Moreover, OpenAPI QL requires that the user be syntactically familiar with SQL-like query languages. However, it is necessary for a user to deepen in REST architectural style but not in OpenAPI 3.0. A simple knowledge of API calls is enough to understand and use OpenAPI QL. To show proof of concept, OpenAPI QL system has been developed that supports query translation, execution and results viewing.
description: Η παρούσα διπλωματική εργασία παρουσιάζει την OpenAPI QL, μία γλώσσα ερωτήσεων δημιουργήμενη να αναζητά σε OpenAPI περιγραφές. Η βασική ιδέα αυτής της υλοποίησης είναι η προσέγγιση των OpenAPI αρχείων ως REST αιτημάτων ενός client στον server, με τις αντίστοιχες απαντήσεις που λαμβάνονται πίσω από τον client. Το βασικό στοιχείο για το οποίο ξεχωρίζει η υλοποίηση είναι η δυνατότητα να διαχωρίζει την χρήσιμη από την λιγότερο χρήσιμη πληροφορία προς αναζήτηση μέσα σε μία OpenAPI περιγραφή. Ο διαχωρισμός της πληροφορίας οδήγησε στην δημιουργία ενός μοντέλου αναζήτησης services σε OpenAPI και κατ’ επέκταση στη δημιουργία της γλώσσας ερωτήσεων OpenAPI QL. Η OpenAPI QL αφορά χρήστες εξοικειώμενους με SQL-like γλώσσες ερωτήσεων, χωρίς απαραίτητα να έχουν εμβαθύνει στη δομή του OpenAPI για να την χρησιμοποιήσουν. Πέρα από την δομή και στην σύνταξη της γλώσσας, σε αυτή την εργασία δίνεται η δυνατότητα στο χρήστη να συντάξει και να εκτελέσει OpenAPI QL ερωτήματα σε μία βάση δεδομένων με OpenAPI περιγραφές, μέσω του OpenAPI QL συστήματος. Το σύστημα δομείται από έναν μεταφραστή μεταξύ της OpenAPI QL και της N1QL και ένα UI για την εκτέλεση των ερωτημάτων από τον χρήστη, όπως επίσης και την εμφάνιση των αποτελεσμάτων προς αυτόν. Τέλος, στην εργασία συμπεριλαμβάνονται τα αποτελέσματα ερωτημάτων που εκτελέστηκαν πειραματικά και ο σχολιασμός τους σε σχέση με την πολυπλοκότητα και τον χρόνο εκτέλεσής τους.

description: With the proposed Hund's rule correlation picture, i.e. the fluctuating Fe local moments with the As-bridged antiferromagnetic superexchange interactions, the exceptional collapsed tetragonal phase and related phase transitions observed in CaFe$_2$As$_2$ are well understood. With the same framework, a pressure-temperature phase diagram is predicted for BaFe$_2$As$_2$ as well, in which a paramagnetic tetragonal and a collinear antiferromagnetic orthorhombic structures to nonmagnetic tetragonal structure transitions take place around 4-8 GPa and 10-15 GPa respectively, and a nonmagnetic tetragonal to a nonmagnetic collapsed tetragonal structure transition takes place over 26 GPa. Our study helps better understand the complex correlation among crystal structure, magnetism, and electronic structure in pnictides, a precondition to understand the superconductivity in pnictides.

description: The spacing of the \{220\} lattice planes of a $^{28}$Si crystal was measured by combined x-ray and optical interferometry to a $3.5\times 10^{-9}$ relative accuracy. The result is $d_{220}=(192014712.67 \pm 0.67)$ am, at 20.0 $^\circ$C and 0 Pa. This value is greater by $(1.9464 \pm 0.0067)\times 10^{-9} d_{220}$ than the spacing in natural Si, a difference which confirms quantum mechanics calculations. Subsequently, this crystal has been used to determine the Avogadro constant by counting the Si atoms, a key step towards a realization of the mass unit based on a conventional value of the Planck or the Avogadro constants.

description: Il lavoro di Tesi ha lo scopo di studiare in che modo l’educazione visiva può essere un contesto per la narrazione di sé nell’eterogeneità di una pluriclasse inclusiva. Il tema principale si riconduce alla comunicazione attraverso le immagini, declinata al racconto di sé attraverso un personale elaborato grafico. Per rispondere alla domanda, è stato istituito un percorso di educazione visiva la cui impostazione si ispira all’arte terapia. Le attività si svolgono seguendo un’organizzazione su tre momenti: concentrazione, elaborazione artistica e condivisione verbale. Durante quest’ultima, le docenti – mediatrici sollecitano il racconto attraverso domande stimolo e infine, vi è un libero scambio di parole tra gli allievi, utilizzando le immagini come terzo oggetto della comunicazione. Gli strumenti utilizzati per la raccolta dati sono: due questionari, le trascrizioni delle condivisioni verbali e l’osservazione delle attività e degli elaborati degli allievi arricchita da appunti personali. Dall’analisi si evince come l’immagine creata sia un valido aiuto per gli allievi nella narrazione di sé all’interno del gruppo classe. L’impostazione del percorso infonde negli allievi emozioni positive, un sano sentimento di stupore volto a vivere un’esperienza estetica e l’apertura al pensiero analogico e alla condivisione di competenze personali con i compagni.

description: Quantum fluctuations constitute the primary noise barrier limiting cavity-based axion dark matter searches. In an experiment designed to mimic a real axion search, we employ a quantum-enhanced sensing technique to detect a synthetic axion-like microwave tone at an unknown frequency weakly coupled to a resonator, demonstrating a factor of 5.6 acceleration relative to a quantum-limited search for the same tone. The acceleration comes from increases to both the visibility bandwidth and the peak visibility of a detector. This speedup is achieved by dynamically coupling the resonator mode to a second (readout) mode with balanced swapping and two-mode squeezing interactions. A small fractional imbalance between the two interaction rates yields further scan rate enhancement and we demonstrate that an 8-fold acceleration can be achieved.

description: We consider supersymmetric models where anomaly and gravity mediation give comparable contributions to the soft terms and discuss how this can be realized in a five-dimensional brane world. The gaugino mass pattern of anomaly mediation is preserved in such a hybrid setup. The flavorful gravity-mediated contribution cures the tachyonic slepton problem of anomaly mediation. The supersymmetric flavor puzzle is solved by alignment. We explicitly show how a working flavor-tachyon link can be realized with Abelian flavor symmetries and give the characteristic signatures of the framework, including O(1) slepton mass splittings between different generations and between doublets and singlets. This provides opportunities for same flavor dilepton edge measurements with missing energy at the Large Hadron Collider (LHC). Rare lepton decay rates could be close to their current experimental limit. Compared to pure gravity mediation, the hybrid model is advantageous because it features a heavy gravitino which can avoid the cosmological gravitino problem of gravity-mediated models combined with leptogenesis.

description: The use of superconducting micro-resonators in combination with quantum-limited Josephson parametric amplifiers has in recent years lead to more than four orders of magnitude improvement in the sensitivity of pulsed Electron Spin Resonance (ESR) measurements. So far, the microwave resonators and amplifiers have been designed as separate components, largely due to the incompatibility of Josephson junction-based devices with even moderate magnetic fields. This has led to complex spectrometers that operate under strict environments, creating technical barriers for the widespread adoption of the technique. Here we circumvent this issue by inductively coupling an ensemble of spins directly to a weakly nonlinear microwave resonator, which is engineered from a magnetic field-resilient thin superconducting film. We perform pulsed ESR measurements with a $1$~pL effective mode volume and amplify the resulting spin signal using the same device, ultimately achieving a sensitivity of $2.8 \times 10^3$ spins in a single-shot Hahn echo measurement at a temperature of 400 mK. We demonstrate the combined functionalities at fields as large as 254~mT, highlighting the technique's potential for application under more conventional ESR operating conditions.

description: In this work, we study the use of asynchronous programming to create a bot for the Telegram messenger. A study of similar functionality of applications for smartphones was conducted. Using the telegram bot api and the aiogram library of the python programming language, a bot was created for the telegram messenger, which helps to learn new and repeat already learned English words. Algorithms for learning, repetition, and statistics processing were developed. The results showed that asynchronous programming provides fast response and high performance of the bot. This work helped to draw conclusions that it is possible to continue its development to a full-fledged service for learning foreign languages, based on the telegram messenger.
Patient perspectives of dysphagia following critical illness and artificial airway use
Creators: name: Fullerton, Geoff
Publisher: name: University of British Columbia
Year: 2021

description: Patients requiring artificial airways and prolonged mechanical ventilation while in critical care frequently suffer from various iatrogenic complications during and after hospitalization. One of these is dysphagia, or disordered swallowing, which can affect over 90% of this population. Patients unable to swallow safely are often at risk of other adverse sequelae, including serious pulmonary complications. Intervention may necessitate tube feeding and/or modified food and/or liquid; as a result, the treatments necessary to sustain life during critical illness may affect psychosocial well-being and quality of life. To date, no study has examined the perspectives of patients with dysphagia following critical illness and artificial airway use. Using a prospective study design, we recruited a convenience sample of patients who had swallowing impairment following artificial airway use from three healthcare facilities in a single health care region. Four patients were recruited to this study from January to April 2021. Using a semi-structured interview format, one interviewer explored their experiences. Following interview transcription, results were analyzed thematically by two reviewers. We identified several common themes reflecting participants’ beliefs and values around eating and drinking, in the context of: 1) connectedness with family, 2) recovery and overall health, and 3) personal autonomy and dignity. We further identified latent patient perceptions of swallowing and instrumental assessment – in particular that swallowing was a volitional action, and that assessments were a test of ability with a binary outcome. This study is the first to investigate the perspectives of a sample of this population. As communication specialists, S-LPs have a vital role to play in fostering effective multi-directional communication between all members of the care team, including the patient and their family. Understanding this role within the context of these patients’ perspectives will enable clinicians to deliver enhanced patient-centered care.

description: Galaxy evolution is driven to a large extent by interactions and mergers with other galaxies and the gas in galaxies is extremely sensitive to the interactions. One method to measure such interactions uses the quantified morphology of galaxy images. Well-established parameters are Concentration, Asymmetry, Smoothness, Gini, and M20 of a galaxy image. Thus far, the application of this technique has mostly been restricted to restframe ultra-violet and optical images. However, with the new radio observatories being commissioned (MeerKAT, ASKAP, EVLA, WSRT/APERTIF, and ultimately SKA), a new window on the neutral atomic hydrogen gas (HI) morphology of a large numbers of galaxies will open up. The quantified morphology of gas disks of spirals can be an alternative indicator of the level and frequency of interaction. The HI in galaxies is typically spatially more extended and more sensitive to low-mass or weak interactions. In this paper, we explore six morphological parameters calculated over the extent of the stellar (optical) disk and the extent of the gas disk for a range of wavelengths spanning UV, Optical, Near- and Far-Infrared and 21 cm (HI) of 28 galaxies from The HI Nearby Galaxy Survey (THINGS). Though the THINGS sample is small and contains only a single ongoing interaction, it spans both non-interacting and post-interacting galaxies with a wealth of multi-wavelength data. We find that the choice of area for the computation of the morphological parameters is less of an issue than the wavelength at which they are measured. The signal of interaction is as good in the HI as in any of the other wavelengths in which morphology has been used to trace the interaction rate to date, mostly star-formation dominated ones (near- and far-ultraviolet). The Asymmetry and M20 parameters are the ones which show the most promise as tracers of interaction in 21 cm line observations.

description: To understand the oscillatory behavior exhibited in the timelike electromagnetic form factors of nucleons, we propose a toy model based on the Jost function of the $N\bar N$ pair into the timelike form factors with the help of the distorted-wave Born approximation. By constructing a simple square-well potential reflecting the final-state interaction of $N\bar N$, we naturally represent the damped oscillatory phenomenon in the timelike electromagnetic form factors of nucleons. Especially, our study reveals that the ``period" of the oscillation is approximately determined by the Yukawa interaction range $1/m_π$. Other possible potentials are also discussed. The threshold enhancements of the cross sections for $e^+e^-\to n\bar n$, $Λ\barΛ$, and $Λ_c\barΛ_c$ can also be understand within this scenario.

Construction of a Microscopic Model for Yb and Tm Compounds on the Basis of a $\mib{j}$-$\mib{j}$ Coupling Scheme

description: We provide a prescription to construct a microscopic model for heavy lanthanide systems such as Yb and Tm compounds by exploiting a $j$-$j$ coupling scheme. Here we consider a situation with a large spin-orbit coupling, in which $j$=5/2 sextet is fully occupied, while $j$=7/2 octet is partially occupied, where $j$ denotes total angular momentum. We evaluate crystalline electric field potentials and Coulomb interactions among the states of the $j$=7/2 octet to construct a local Hamiltonian in the $j$-$j$ coupling scheme. Then, it is found that the local $f$-electron states composed of the $j$=7/2 octet agree quite well with those of seven $f$ orbitals even for a realistic value of the spin-orbit coupling. As an example of the application of the present model, we discuss low-temperature multipole states of Yb- and Tm-based filled skutterudites by analyzing multipole susceptibility of the Anderson model in the $j$-$j$ coupling scheme with the use of a numerical renormalization group technique. From the comparison with the numerical results of the seven-orbital Anderson model, it is concluded that the multipole state is also well reproduced by the $j$-$j$ coupling model, even when we include the hybridization between conduction and $f$ electrons for the realistic value of the spin-orbit coupling. Finally, we briefly discuss future applications of the present prescription for theoretical research on heavy lanthanide compounds.

description: We have discovered an accreting black hole (BH) in a spectroscopically confirmed globular cluster (GC) in NGC 1399 through monitoring of its X-ray activity. The source, with a peak luminosity of L_x=2x10^39 ergs/s, reveals an order of magnitude change in the count rate within ~10 ks in a Chandra observation. The BH resides in a metal-rich [Fe/H]~0.2 globular cluster. After RZ2109 in NGC 4472 this is only the second black-hole X-ray source in a GC confirmed via rapid X-ray variability. Unlike RZ2109, the X-ray spectrum of this BH source did not change during the period of rapid variability. In addition to the short-term variability the source also exhibits long-term variability. After being bright for at least a decade since 1993 within a span of 2 years it became progressively fainter, and eventually undetectable, or marginally detectable, in deep Chandra and XMM observations. The source also became harder as it faded. The characteristics of the long term variability in itself provide sufficient evidence to identify the source as a BH. The long term decline in the luminosity of this object was likely not recognized in previous studies because the rapid variability within the bright epoch suppressed the average luminosity in that integration. The hardening of the spectrum accompanying the fading would also make this black hole source indistinguishable from an accreting neutron star in some epochs. Therefore some low mass X-ray binaries identified as NS accretors in snapshot studies of nearby galaxies may also be BHs. Thus the discovery of the second confirmed BH in an extragalactic GC through rapid variability at the very least suggests that accreting BHs in GCs are not exceedingly rare occurences.
