description: We aggregate the transverse momentum spectra of $J/ψ$ mesons produced in high energy gold-gold (Au-Au), deuteron-gold ($d$-Au), lead-lead (Pb-Pb), proton-lead ($p$-Pb), and proton-(anti)proton ($p$-$p(\overline{p})$) collisions measured by several collaborations at the Relativistic Heavy Ion collider (RHIC), the Tevatron Proton-Antiproton Collider, and the Large Hadron Collider (LHC). The collision energy (the center-of-mass energy) gets involved in a large range from dozens of GeV to 13 TeV (the top LHC energy). We consider two participant or contributor partons, a charm quark and an anti-charm quark, in the production of $J/ψ$. The probability density of each quark is described by means of the modified Tsallis--Pareto-type function (the TP-like function) while considering that both quarks make suitable contributions to the $J/ψ$ transverse momentum spectrum. Therefore, the convolution of two TP-like functions is applied to represent the $J/ψ$ spectrum. We adopt the mentioned convolution function to fit the experimental data and find out the trends of the power exponent, effective temperature, and of the revised index with changing the centrality, rapidity, and collision energy. Beyond that, we capture the characteristic of $J/ψ$ spectrum, which is of great significance to better understand the production mechanism of $J/ψ$ in high energy collisions.

description: Obwohl die Theatralisierung der Musik ein entscheidender Aspekt der Neuen Musik ist, der im Szenario nach 1945 noch mehr an Bedeutung gewinnt, kann die aber auch als Ausdruck einer musikalischen Wende zum Leib verstanden werden. Um von einer Wende zum Leib in der Musik zu sprechen, muss man auch eine Form des Dualismus zu überwinden. Durch die Werke avantgardistischer Komponisten wird in dieser Arbeit versucht, ein Verständnis der Musikwahrnehmung aufzubauen.
description: It is our thesis that, even though the theatricalization of music is a crucial aspect of the Neue Musik – one that gain even more prominence on the post-1945 scenario –, it is also an expression of a corporeal turn in music. To speak of a corporeal turn in music also means an attempt to overcome a form of dualism. It is an attempt to unify music making and music perception. This is what will be attempted here. Through the works of avant-garde composers, an attempt to build an understanding of music perception in the context of a corporeal turn in music will be made. From the perception of the body and corporeity to the move from “listening” to “perceiving” and, finally, in the concept of the work of music as a phenomenal field, a physiological perception of the avant-garde will be developed.

description: Uterine fibroids is the most common tumour of the reproductive system. Despite the presence of a large number of ongoing studies, the study of this pathology is still relevant due to many unresolved pathogenesis issues. The pres-ence of genetic predisposition, belonging to the black race, age, especially late reproductive, early menarche, absence of births in the history and, of course, obesity are considered as risk factors for uterine fibroids development. In this re-gard, the study aimed to study the relationship between fetal macrosomia, obesity and the risk of the formation of hor-mone-dependent tumours of the genitals. The research methods included the study of apoptosis processes in simple and proliferating uterine fibroids by determining the level of the ligand inducing apoptosis, which made it possible to iden-tify a group of patients with a high proliferative activity of myomatous nodes, and when analyzing the patient histories, the most significant signs and characteristics were identified, in the presence of which significantly increases the likeli-hood of detecting uterine fibroids.
The results of the study presented in this paper allow us to set the necessary accents and form risk groups for uterine fibroids development and, above all, the most mitotically active variant - proliferating uterine fibroids.
Key words: simple uterine fibroids, proliferating uterine fibroids, risk factors, pelvic ultrasound, macrosomia, obesity.

description: Biological membranes undergo noticeable thermal fluctuations at physiological temperatures. When two membranes approach each other, they hinder the out of plane fluctuations of the other. This hindrance leads to an entropic repulsive force between membranes which, in an interplay with attractive and repulsive forces due to other sources, impacts a range of biological functions: cell adhesion, membrane fusion, self-assembly, binding-unbinding transition among others. In this work, we take cognizance of the fact that biological membranes are not purely mechanical entities and, due to the phenomenon of flexoelectricity, exhibit a coupling between deformation and electric polarization. The ensuing coupled mechanics-electrostatics-statistical mechanics problem is analytically intractable. We use a variational perturbation method to analyze, in closed-form, the contribution of flexoelectricity to the entropic force between two fluctuating membranes and discuss its possible physical implications. We find that flexoelectricity leads to a correction that switches from an enhanced attraction at close membrane separations and an enhanced repulsion when the membranes are further apart.

The Evolution and Trajectory of Ergonomic Hazards in the Warehousing Industry: A Mixed-Methods Approach
Creators: name: Espinosa-Ravi, Vinay
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Working conditions in the warehousing industry have rightfully come under public scrutiny in recent years. Warehouse workers are a highly contingent workforce characterized by high turnover rates and the use of temporary or seasonal workers. Contributing to the burden of injuries, E-commerce growth has increased the speed, repetitiveness, and variability of warehouse work. This study looks at State of Illinois Workers’ Compensation data from 2018 through 2021 to understand and characterize injury patterns in the warehousing industry. More specifically, the project looks at 1). Differences in injury claims between peak and non-peak seasons, 2). How injury claims from E-commerce warehouses differ from more traditional warehouses, and 3). How warehousing experts thematize the shifting determinants of injury patterns in the industry. The study employed a mixed-methods sequential explanatory design in which the research process was bifurcated into two separate phases: a quantitative phase followed by a qualitative phase; the qualitative findings were used to “refine and explain” the quantitative results, as well as to provide general context for the research aims.

The quantitative findings demonstrated that e-commerce warehouses differed from other warehouses in terms of both seasonality, job tenure patterns, and injury claim characteristics. Statistically significant seasonal increases in monthly injury claims were observed only among e-commerce warehouses. The qualitative analysis described a multi-level process of injury causation whereby industry-level competition for consumer demand pushed e-commerce warehouses to organize work towards faster production speeds, leading to greater biomechanical and psychosocial hazard exposures among workers in these facilities. After integrating the quantitative and qualitative finding, the observed seasonal injury claim spikes are best interpreted as a window into the growing gap between the technical capacity to move goods through e-commerce warehouses and the capacity of workers to keep pace with corresponding production quotas. The findings of this mixed-methods study help construct a model of injury causation in e-commerce warehouses that may be informative for future health and safety regulatory efforts.

description: Millions of measuring instruments are verified each year before being placed on the markets worldwide. In the EU, such initial conformity assessments are regulated by the Measuring Instruments Directive (MID). The MID modules F and F1 on product verification allow for statistical acceptance sampling, whereby only random subsets of instruments need to be inspected. This paper re-interprets the acceptance sampling conditions formulated by the MID. The new interpretation is contrasted with the one advanced in WELMEC guide 8.10, and three advantages have become apparent. Firstly, an economic advantage of the new interpretation is a producers' risk bounded from above, such that measuring instruments with sufficient quality are accepted with a guaranteed probability of no less than 95 %. Secondly, a conceptual advantage is that the new MID interpretation fits into the well-known, formal framework of statistical hypothesis testing. Thirdly, the new interpretation applies unambiguously to finite-sized lots, even very small ones. We conclude that the new interpretation is to be preferred and suggest re-formulating the statistical sampling conditions in the MID. Re-interpreting the MID conditions implies that currently available sampling plans are either not admissible or not optimal. We derive a new acceptance sampling scheme and recommend its application.

description: Mechanically interlocked molecules have marked a breakthrough in the field of topological chemistry and boosted the vigorous development of molecular machinery. As an archetypal example of the interlocked molecules, catenanes comprise macrocycles that are threaded through one another like links in a chain. Inspired by the transition metal-templated approach of catenanes synthesis, the hierarchical assembly of DNA origami catenanes templated by gold nanoparticles is demonstrated in this work. DNA origami catenanes, which contain two, three or four interlocked rings are successfully created. In particular, the origami rings within the individual catenanes can be set free with respect to one another by releasing the interconnecting gold nanoparticles. This work will set the basis for rich progress toward DNA-based molecular architectures with unique structural programmability and well-defined topology.

description: In this paper we characterize magnitude-dependent systematics in the proper motions of the Gaia EDR3 catalog and provide a prescription for their removal. The reference frame of bright stars (G<13) in EDR3 is known to rotate with respect to extragalactic objects, but this rotation has proven difficult to characterize and correct. We employ a sample of binary stars and a sample of open cluster members to characterize this proper motion bias as a magnitude-dependent spin of the reference frame. We show that the bias varies with G magnitude, reaching up to 80 μas/yr for sources in the range G = 11 - 13, several times the formal EDR3 proper motion uncertainties. We also show evidence for an additional dependence on the color of the source, with a magnitude up to 10 μas/yr. However, a color correction proportional to the effective wavenumber is unsatisfactory for very red or very blue stars and we do not recommend its use. We provide a recipe for a magnitude-dependent correction to align the proper motion of the Gaia EDR3 sources brighter than G=13 with the International Celestial Reference Frame.

Chemical and morphological factors of resistance against the twospotted spider mite (Tetranychus urticae Koch) in beach strawberry Fragaria chiloensis (L.) Duchesne
Creators: name: Luczynski, Anna
Publisher: name: University of British Columbia
Year: 2010

description: Host-plant resistance is an important component of integrated pest management. Host resistance to phytophagous insects and mites based on chemical and morphological characteristics has been identified in various agronomic crops. The present study was undertaken to examine how variation in selected morphological and chemical characteristics of beach strawberry Fragaria chiloensis (L.) Duchesne affects population parameters of the twospotted spider mite Tetranychus urticae Koch. The results from this study show that clones of F. chiloensis and the cultivar "Totem" vary in suitability for the twospotted spider mite. Selected clones of F. chiloensis and the cultivar "Totem" differed also in the following foliar characteristics: densities of glandular and nonglandular trichomes and concentrations of total and catechol-based phenolics. In contrast, qualitative analysis of phenolic compounds, determined via HPLC, revealed a close similarity between F. chiloensis and F. x ananassa (cultivated strawberry) and among selected clones of F. chiloensis. Mite oviposition was negatively correlated with densities of glandular and nonglandular trichomes and concentrations of total foliar phenolics. In spite of these significant relationships, mite oviposition was best predicted by a combination of interacting plant characteristics rather than by any individual characteristic. Entrapment by sticky exudates from glandular trichomes appears to explain the negative relationship between mite survival and density of glandular trichomes. Spider mite development was negatively related to concentrations of foliar phenolics; twospotted spider mite development is delayed on leaves with high concentrations of phenolics. The correlation between mite development and foliar phenolics was greater when catechol-based phenolics were used.
Nucleoporin93 (Nup93) Promotes Vascular Health by Limiting Endothelial Cell Aging and Dysfunction
Creators: name: Nguyen, Tung
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Endothelial cells (ECs) serve as a selective monolayer to mediate blood vessel integrity for vascular function, and EC health is in turn increasingly acknowledged as a crucial factor in limiting age-induced vessel dysfunction. Conversely, chronic inflammation and natural aging drive pro-inflammatory endothelial changes, resulting in EC activation and vessel leakage to precipitate vascular disease. Recent studies report increased nuclear leakiness with aging, displaying the significance of proper nucleocytoplasmic transport for cellular health. As the major regulator of molecular transport across the nuclear envelope, the nuclear pore complex (NPC) in ECs may also be compromised with age to drive vascular disease.
Our exciting studies implicate nucleoporin93 (Nup93), a crucial structural NPC protein, as an indispensable player for EC health and vascular protection. We observe a significant reduction in endothelial Nup93 expression in the coronary vasculature of aged mice. Moreover, we find that endothelial loss of Nup93 induces cellular senescence and promotes the surface expression of pro-inflammatory adhesion molecules for enhanced EC-monocyte interaction. Mechanistically, endothelial Nup93 deficiency leads to nuclear leakiness for increased nuclear localization of Yap, a transcription co-factor known to activate EC inflammation. Pharmacological inhibition of Yap activity in Nup93-null ECs reverses the senescence and inflammatory phenotypes, indicating Yap hyperactivation as a major consequence of Nup93 deficiency in ECs.
Furthermore, Nup93 loss in human ECs leads to actin stress fiber formation, impaired eNOS-dependent nitric oxide (NO) bioavailability, and enhanced in vitro paracellular permeability. Mechanistically, endothelial Nup93 depletion significantly decreases Sun1 levels, a component of the linker of the nucleoskeleton and cytoskeleton (LINC) complex necessary to connect the nucleus with the cytoskeleton. Endothelial loss of Nup93 also results in a concomitant increase in RhoA activity, where the re-introduction of Sun1 in Nup93-deficient ECs mitigates RhoA activation to restore endothelial barrier function and NO production. Our studies not only show Sun1 as a negative regulator of endothelial RhoA activity, but also implicate Nup93 as a necessary component in preventing aberrant RhoA signaling. Overall, the dissertation herein highlights the previously unrecognized role of NPC proteins in limiting endothelial senescence and dysfunction, thus providing novel insight into the molecular mechanisms underlying vascular aging and disease progression.
Modifying quantum walks: A scattering theory approach

Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We show how to construct discrete-time quantum walks on directed, Eulerian graphs. These graphs have tails on which the particle making the walk propagates freely, and this makes it possible to analyze the walks in terms of scattering theory. The probability of entering a graph from one tail and leaving from another can be found from the scattering matrix of the graph. We show how the scattering matrix of a graph that is an automorphic image of the original is related to the scattering matrix of the original graph, and we show how the scattering matrix of the reverse graph is related to that of the original graph. Modifications of graphs and the effects of these modifications are then considered. In particular we show how the scattering matrix of a graph is changed if we remove two tails and replace them with an edge or cut an edge and add two tails. This allows us to combine graphs, that is if we connect two graphs we can construct the scattering matrix of the combined graph from those of its parts. Finally, using these techniques, we show how two graphs can be compared by constructing a larger larger graph in which the two original graphs are in parallel, and performing a quantum walk on the larger graph. This is a kind of quantum walk interferometry.

description: The complexity is increasing rapidly in many areas of the automotive industry. The design of an automobile involves many different engineering disciplines, e. g., mechanical, electrical, and software engineering. The software of a vehicle comprises millions of lines of code. Further, the manufacturing, logistics, distribution, and sales of a vehicle are highly complex. There is an immense need for solving simulation problems, e. g., in battery chemistry, an essential enabler for technological advancements for electric vehicles. In all these domains, myriads of optimization, simulation, and machine learning problems arise. Quantum computing-based approaches promise to overcome some of the inherent scalability limitations of classical approaches. This article investigates quantum computing applications across the automotive value chain and identifies several high-value problems that will benefit from quantum-enhanced solutions.

description: By means of contractions of Lie algebras, we obtain new classes of indecomposable quasi-classical Lie algebras that satisfy the Yang-Baxter equations in its reformulation in terms of triple products. These algebras are shown to arise naturally from non-compact real simple algebras with non-simple complexification, where we impose that a non-degenerate quadratic Casimir operator is preserved by the limiting process. We further consider the converse problem, and obtain sufficient conditions on integrable cocycles of quasi-classical Lie algebras in order to preserve non-degenerate quadratic Casimir operators by the associated linear deformations.

Connecting GRBs and galaxies: the probability of chance coincidence

Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Studies of GRB host galaxies are crucial to understanding GRBs. However, since they are identified by the superposition in the plane of the sky of a GRB afterglow and a galaxy there is always a possibility that an association represents a chance alignment, rather than a physical connection. We examine a uniform sample of 72 GRB fields to explore the probability of chance superpositions. There is typically a ~1% chance that an optical afterglow will coincide with a galaxy by chance. While spurious host galaxy detections will, therefore, be rare, the possibility must be considered when examining individual GRB/host galaxy examples. It is also tempting to use the large and uniform collection of X-ray afterglow positions to search for GRB-associated galaxies. However, we find that approximately half of the 14 superpositions in our sample are likely to occur by chance, so in the case of GRBs localized only by an X-ray afterglow, even statistical studies are suspect.

description: We present the first multi-epoch study that includes concurrent mid-infrared and radio interferometry of an oxygen-rich Mira star. We obtained mid-infrared interferometry of S Ori with VLTI/MIDI at four epochs between December 2004 and December 2005. We concurrently observed v=1, J=1-0 (43.1 GHz), and v=2, J=1-0 (42.8 GHz) SiO maser emission toward S Ori with the VLBA at three epochs. The MIDI data are analyzed using self-excited dynamic model atmospheres including molecular layers, complemented by a radiative transfer model of the circumstellar dust shell. The VLBA data are reduced to the spatial structure and kinematics of the maser spots. The modeling of our MIDI data results in phase-dependent continuum photospheric angular diameters between about 7.9 mas (Phase 0.55) and 9.7 mas (Phase 1.16). The dust shell can best be modeled with Al2O3 grains using phase-dependent inner boundary radii between 1.8 and 2.4 photospheric radii. The dust shell appears to be more compact with greater optical depth near visual minimum, and more extended with lower optical depth after visual maximum. The ratios of the SiO maser ring radii to the photospheric radii are between about 1.9 and 2.4. The maser spots mark the region of the molecular atmospheric layers just beyond the steepest decrease in the mid-infrared model intensity profile. Their velocity structure indicates a radial gas expansion. Al2O3 dust grains and SiO maser spots form at relatively small radii of 1.8-2.4 photospheric radii. Our results suggest increased mass loss and dust formation close to the surface near the minimum visual phase, when Al2O3 dust grains are co-located with the molecular gas and the SiO maser shells, and a more expanded dust shell after visual maximum. Silicon does not appear to be bound in dust, as our data show no sign of silicate grains.

description: Hyperspectral imaging measures the amount of electromagnetic energy across the instantaneous field of view at a very high resolution in hundreds or thousands of spectral channels. This enables objects to be detected and the identification of materials that have subtle differences between them. However, the increase in spectral resolution often means that there is a decrease in the number of photons received in each channel, which means that the noise linked to the image formation process is greater. This degradation limits the quality of the extracted information and its potential applications. Thus, denoising is a fundamental problem in hyperspectral image (HSI) processing. As images of natural scenes with highly correlated spectral channels, HSIs are characterized by a high level of self-similarity and can be well approximated by low-rank representations. These characteristics underlie the state-of-the-art methods used in HSI denoising. However, where there are rarely occurring pixel types, the denoising performance of these methods is not optimal, and the subsequent detection of these pixels may be compromised. To address these hurdles, in this article, we introduce RhyDe (Robust hyperspectral Denoising), a powerful HSI denoiser, which implements explicit low-rank representation, promotes self-similarity, and, by using a form of collaborative sparsity, preserves rare pixels. The denoising and detection effectiveness of the proposed robust HSI denoiser is illustrated using semireal and real data.

description: The magnetoresistance of the MBE-grown GaAs/AlGaAs superlattice with Si-doped barriers has been measured in tilted magnetic fields in the as-grown state, and after brief illumination by a red-light diode at low temperature, T is approximately 0.3 K. A remarkable illumination-induced modification of magnetoresistance curves has been observed, which indicates a significant change of the superlattice Fermi surface topology. Analysis of magnetoresistance data in terms of the tight-binding model reveals that not only electron concentration and mobility have been increased by illumination, but also the coupling among 2D electron layers in neighboring quantum wells has been reduced.

description: Rural communities in the Northern Great Plains (Montana, North Dakota, and Wyoming) must plan for the impacts of large-scale development of the coal deposits in the area. In the long run, communities gaining population because of the new developments, but unable to tax the new mine or powerplant, will probably experience financial problems. In the short run, most affected communities will probably experience front-end cash flow problems due to lags in collecting revenues from the new projects. The combined effects of several new mines and powerplants in a limited geographic area may exceed the capacity of the community to provide services at existing levels.
Asymptotic behavior of the rate of adaptation

description: We consider the accumulation of beneficial and deleterious mutations in large asexual populations. The rate of adaptation is affected by the total mutation rate, proportion of beneficial mutations and population size $N$. We show that regardless of mutation rates, as long as the proportion of beneficial mutations is strictly positive, the adaptation rate is at least $\mathcal{O}(\log^{1-δ}N)$ where $δ$ can be any small positive number, if the population size is sufficiently large. This shows that if the genome is modeled as continuous, there is no limit to natural selection, that is, the rate of adaptation grows in $N$ without bound.

description: Η παρούσα εργασία αποτελεί προτεινόμενη διδακτική εφαρμογή και αποβλέπει στην ανάλυση ενός διαθεματικού σχεδίου δράσης βασισμένου στο Μουσείο Φυσικής Ιστορίας Γουλανδρή. Δεδομένου ότι τα μουσεία αποτελούν χώρους μάθησης όχι μόνο
για τους επισκέπτες σε αυτά αλλά και για το ίδιο το σχολικό περιβάλλον έχει διαμορφωθεί ένα σχέδιο εργασίας το λεγόμενο project, το οποίο δυνητικά μπορεί να αξιοποιηθεί στα πλαίσια της Ευέλικτης Ζώνης. Σκοπός θεωρείται η απόκτηση γνώσεων σχετικών με τα ζώα και το περιβάλλον και η διαμόρφωση φιλικών στάσεων προς το περιβάλλον για την ενδυνάμωση της αειφορίας. Στη διδασκαλία αξιοποιείται σε μεγάλο βαθμό
η διαδικτυακή περιήγηση που προσφέρεται μέσω της ιστοσελίδας του μουσείου. Η εκπαιδευτική αυτή καινοτομία της σύζευξης διαθεματικών σχεδίων διδασκαλίας με ψηφιακό τρόπο συμβάλλει στη διατήρηση του ενδιαφέροντος των μαθητών, στην έξαψη
της φαντασίας τους, στη διαμόρφωση της κριτικής σκέψης τους, στη διεύρυνση των πνευματικών τους οριζόντων καθώς και στη προαγωγή της γνώσης εφόσον οι μαθητές πράγματι μαθαίνουν χωρίς να οδηγούνται στη στείρα απομνημόνευση όπως συμβαίνει
με το παραδοσιακό τρόπο διδασκαλίας όπου τα διδακτικά αντικείμενα διδάσκονται ξεχωριστά με μόνο μέσο το σχολικό εγχειρίδιο. Παρουσιάζεται αναλυτικά η διδακτική μέθοδος με έμφαση στην ομαδοσυνεργατική μέθοδο. Οι συμμετέχοντες είναι μαθητές της  ΣΤ΄ Δημοτικού. Αξιοποιούνται δύο θεματικές του μουσείου «Σπονδυλόζωα» και «Εντομολογία» πάνω στις οποίες είναι βασισμένα τα δύο διαθεματικά σχέδια εργασίας «Τα ζώα της στεριάς» και «Τα έντομα» αντίστοιχα. Στα διαθεματικά σχέδια διδασκαλίας επισημαίνονται οι διδακτικοί στόχοι καθώς και τα μέσα και υλικά που θα χρησιμοποιηθούν και περιγράφονται η εκπαιδευτική μεθοδολογία, οι ενδεικτικές δραστηριότητες καθώς
και η σχετική αξιολόγησή τους. Η αξιολόγηση των διδακτικών στόχων επιτυγχάνεται με ένα συνδυασμό παραδοσιακών μεθόδων όπως είναι οι προφορικές ερωτήσεις, ο ημιδομημένος διάλογος, η συστηματική παρατήρηση αλλά και πιο εναλλακτικών μεθόδων όπως είναι το παιχνίδι ρόλων και η αυτοαξιολόγηση μέσω ερωτηματολογίων. Στα συμπεράσματα υπογραμμίζεται η συμβολή του μουσείου στην εκπαίδευση ως ένα μέσο που προσφέρει στους μαθητές ποικίλα ερεθίσματα και ειδικότερα επισημαίνεται η συνεισφορά του Μουσείου Γουλανδρή Φυσικής Ιστορίας στην διαμόρφωση συμπεριφοράς που οδηγεί στην αειφόρο ανάπτυξη.

description: We calculate the tunneling density of states for a Tomonaga-Luttinger liquid placed under a strong bias voltage. For the tunneling through a side-coupled point contact, one can observe the power law singularities in the tunneling density of states separately for the right- and left-movers despite the point-like tunnel contact. Deviations of the nonequilibrium tunneling exponents from the equilibrium case are discussed.

description: Constructing quantum circuits for efficient state preparation belongs to the central topics in the field of quantum information and computation. As the number of qubits grows fast, methods to derive large-scale quantum circuits are strongly desired. In this work, we propose the automatically differentiable quantum circuit (ADQC) approach to efficiently prepare arbitrary quantum many-qubit states. A key ingredient is to introduce the latent gates whose decompositions give the unitary gates that form the quantum circuit. The circuit is optimized by updating the latent gates using back propagation to minimize the distance between the evolved and target states. Taking the ground states of quantum lattice models and random matrix product states as examples, with the number of qubits where processing the full coefficients is unlikely, ADQC obtains high fidelities with small numbers of layers $N_L \sim O(1)$. Superior accuracy is reached compared with the existing state-preparation approach based on the matrix product disentangler. The parameter complexity of MPS can be significantly reduced by ADQC with the compression ratio $r \sim O(10^{-3})$. Our work sheds light on the "intelligent construction" of quantum circuits for many-qubit systems by combining with the machine learning methods.

description: Η Εκπαίδευση μέσω της Τέχνης, όπως και η αξιοποίηση της Τέχνης μέσω της Εκπαίδευσης, καθίσταται ολοένα και πιο συστηματική τα τελευταία χρόνια. Η αξιοποίηση των έργων τέχνης στα αναλυτικά προγράμματα σπουδών όλων των εκπαιδευτικών βαθμίδων προσφέρει ευκαιρίες για την ολόπλευρη ανάπτυξη των μαθητών.Έτσι, η Τέχνη καλλιεργεί τις αισθήσεις, τη φαντασία, τη δημιουργική και κριτική σκέψη, τη στοχαστική παρατήρηση, ενώ ταυτόχρονα αναπτύσσονται βασικές δεξιότητες,
που είναι απαραίτητες για την καθημερινή ζωή του ατόμου. Η ρομποτική αποτελεί μια σύγχρονη επιστήμη που παρέχει ποικίλα εργαλεία και στον εκπαιδευτικό χώρο, με σκοπό τη διαμόρφωση ενός αλληλεπιδραστικού και συνεργατικού πλαισίου ευχάριστης και παιγνιώδους μάθησης. Ειδικότερα, η χρήση της Bee-Bot (ΒΒ), μιας ρομποτικής ‘μελισσούλας’, αναδεικνύει αφενός τη σπουδαιότητα των βιωματικών παιχνιδιών προγραμματισμού για νήπια και αφετέρου αποτελεί το κίνητρο για διεπιστημονικές προσεγγίσεις. Ταυτόχρονα, η διερευνητική μάθηση αποτελεί το ευρύτερο πεδίο υλοποίησης των δράσεων της εκπαιδευτικής ρομποτικής. Σκοπός της παρούσας μελέτης αποτελεί αφενός η παρουσίαση του θεωρητικού πλαισίου σχετικά με την τέχνη και την εκπαιδευτική ρομποτική για μικρά παιδιά και αφετέρου η ανάδειξη της χρήσης της Bee-bot σε μια εκπαιδευτική εφαρμογή με επίκεντρο το Μουσείο Νεοελληνικής Τέχνης του Δήμου Ρόδου (Νεστορίδειο Μέλαθρο).
