description: An important problem in space-time adaptive detection is the estimation of the large p-by-p interference covariance matrix from training signals. When the number of training signals n is greater than 2p, existing estimators are generally considered to be adequate, as demonstrated by fixed-dimensional asymptotics. But in the low-sample-support regime (n < 2p or even n < p) fixed-dimensional asymptotics are no longer applicable. The remedy undertaken in this paper is to consider the "large dimensional limit" in which n and p go to infinity together. In this asymptotic regime, a new type of estimator is defined (Definition 2), shown to exist (Theorem 1), and shown to be detection-theoretically ideal (Theorem 2). Further, asymptotic conditional detection and false-alarm rates of filters formed from this type of estimator are characterized (Theorems 3 and 4) and shown to depend only on data that is given, even for non-Gaussian interference statistics. The paper concludes with several Monte Carlo simulations that compare the performance of the estimator in Theorem 1 to the predictions of Theorems 2-4, showing in particular higher detection probability than Steiner and Gerlach's Fast Maximum Likelihood estimator.

Towards More Efficient and Data-Driven Domain Adaptation

Publisher: name: Carnegie Mellon University

Subjects: Applied Computer Science

description: In recent years with the fast progress made in neural networks research, supervised machine learning approaches have become increasingly powerful in finding flexible functions to predict target variable Y from input features X. However, most of these complex models require a large amounts of data to train, and often work under the assumption that the data points are i.i.d. In reality these assumptions are very likely to be violated. A simplified notion of this violation is when the training and the test datasets come from different joint distributions (i.e. P train(X, Y ) 6= P test(X, Y )). In this setting, where the training and test datasets are also known as source and target domains respectively, domain adaptation is required to obtain good performance. In particular, when only unlabeled features are observed in the target domain, this setting is referred to as unsupervised domain adaptation, and it will be the main focus of this thesis. Domain adaptation is a wide sub-field of machine learning with the task of designing algorithms to account for this distributional difference under specific assumptions, for the purpose of better prediction performance in the target domain. In this thesis we make use of the data-generating process to address several subproblems of unsupervised domain adaptation. Namely, we first address the problem of unsupervised domain adaptation with multiple labeled source domains and an unlabeled target domain under the conditional-target shift setting, and we present an approach to capture the low-dimensional changes of the joint distribution across domains in order to perform prediction in the target domain. Secondly, we introduce an algorithm to reduce the dimensionality of the data when performing domain adaptation under the covariate shift setting. In particular, we make use of the particular properties of the covariate shift setting in order to reduce the dimensionality of the data such that we preserve relevant predictive information about the target variable Y . We further investigate domain adaptation from the perspective of the data-generating process when addressing the problem using neural networks. Deep neural architectures are commonly used to extract domain-invariant representations from the observed features. However, without labels in the target domain, there is no guarantee that these representations will have relevant predictive information for the target domain data. In this thesis, we investigate techniques to regularize this invariant representation in order to enforce that it has non-trivial structure which contains information which is relevant for predicting Y in the target domain. The first of these techniques is based on mutual information, and the second technique makes use of a novel criterion of distortion of the marginal distribution when transforming it from the source to the target domain.

Housing for seniors: an analysis of housing alternatives for the Kitakyushu population
Creators: name: Izuhara, Misa
Publisher: name: University of British Columbia
Year: 2009

description: Japan has experienced significant changes in its age structure since 1970. Not only is the population aging, but also seniors' lifestyles have been changing significantly. The changes are creating demand for seniors housing, including alternatives to institutions and the traditional extended-family houses. Supportive (congregate) housing for seniors, which is planned to promote their independent living with some support services, is the main theme of this thesis. The need for studies that examine alternative housing models, and housing policy in municipal levels have become increasingly apparent in recent years, since the new and growing demands are not synchronized with current housing provisions. One methodology applied in this thesis is population projection, which helps to identify current and future problems of Kitakyushu City, Japan. Another is a case study of Greater Vancouver experiences through a series of interviews, which expands housing options and opportunities for accommodating seniors in Kitakyushu City. The results of the population projection highlight the coming "aged society" with increasing numbers of seniors-only-households, which require revaluation of the city's housing policy. Given the increasing demands for housing alternatives, also based on literature review, the city's pressing need for an innovative response to such housing issues is further complicated by the fact that no single model provides a simple and final solution. Alternative means of project financing, service provision, and alternative models of housing and its operation are explored within the context of scarce government resources. All three housing projects in Greater Vancouver respond in a unique way to the needs of seniors with moderate incomes. The analyses reveal that providing a sufficient number of options for choices with a mixture of approaches is a key aspect of planning. Specific policy implications include cooperation and collaboration among various key housing players, alternative means of service provision, and also utilizing more community resources and non-profit human capitals. The equity co-op model is a cost-effective alternative for senior homeowners. Congregate housing is one responsive option which keeps seniors in the community and out of institutions. Also, locating housing adjacent to services is another progressive solution for the city's future housing development.

description: Various families of charge-one vortex solitons in two-dimensional periodic media are reported. These vortices reside either in the semi-infinite gap or higher band gaps of the media. For both Kerr and saturable nonlinearities (either focusing or defocusing), infinite vortex families are found. All these families do not bifurcate from Bloch bands; rather, they turn around before reaching edges of Bloch bands. It is further revealed that vortices with drastically different topological shapes can belong to the same vortex family, which is quite surprising.

description: In this paper we continue analysis of the Matrix theory describing the DLCQ of type IIB string theory on AdS_5 x S^5 (and/or the plane-wave) background, i.e. the Tiny Graviton Matrix Theory (TGMT)[hep-th/0406214]. We study and classify 1/2, 1/4 and 1/8 BPS solutions of the TGMT which are generically of the form of rotating three brane giants. These are branes whose shape are deformed three spheres and hyperboloids. In lack of a classification of such ten dimensional type IIb supergravity configurations, we focus on the dual N=4 four dimensional 1/2, 1/4 and one 1/8 BPS operators and show that they are in one-to-one correspondence with the states of the same set of quantum numbers in TGMT. This provides further evidence in support of the Matrix theory.

Ο λόγος για το οποίο εξετάζονται οι απόψεις του φιλοσόφου πάνω στις συγκεκριμένες τέχνες, οφείλεται στο γεγονός ότι ο ίδιος δίνει περισσότερη βαρύτητα σε αυτές τις δύο απ’ ότι σε αυτές της αρχιτεκτονικής και της γλυπτικής. Γενικότερα, στην παρούσα εργασία, γίνεται εκτενής αναφορά και ανάλυση όλων όσων υποστηρίζει για τη μουσική και τη ζωγραφική, με απώτερο σκοπό, να γίνει κατανοητός ο τρόπος με τον οποίo θεωρεί ο Πλάτωνας, ότι μπορούν οι προαναφερθείσες τέχνες να συμβάλλουν στην ηθική βελτίωση και πνευματική καλλιέργεια των πολιτών μιας κοινωνίας.
description: The scope of this thesis is to study Plato’s views on the art of music and the art of painting as far as visual arts are concerned. The reason why the focus is set on this particular set of arts derives from the fact that Plato himself attributes more weight on these compared to architecture and sculpture. On the whole, within the context of this study, an extensive report and analysis of all that he supports in reference to music and painting takes place. The final objective is to clarify the way in which according to Plato the prementioned arts could serve the moral uplifting and intellectual sophistication of the citizens of a society.

description: We report the first map of large-scale (10 pc in length) emission of millimeter-wavelength hydrogen recombination lines (mm-RRLs) toward the giant H II region around the W43-Main young massive star cluster (YMC). Our mm-RRL data come from the IRAM 30 m telescope and are analyzed together with radio continuum and cm-RRL data from the Karl G. Jansky Very Large Array and HCO$^{+}$ 1-0 line emission data from the IRAM 30 m. The mm-RRLs reveal an expanding wind-blown ionized gas shell with an electron density ~70-1500 cm$^{-3}$ driven by the WR/OB cluster, which produces a total Ly$α$ photon flux of 1.5 x 10$^{50}$ s$^{-1}$. This shell is interacting with the dense neutral molecular gas in the W43-Main dense cloud. Combining the high spectral and angular resolution mm-RRL and cm-RRL cubes, we derive the two-dimensional relative distributions of dynamical and pressure broadening of the ionized gas emission and find that the RRL line shapes are dominated by pressure broadening (4-55 km s$^{-1}$) near the YMC and by dynamical broadening (8-36 km s$^{-1}$) near the shell's edge. Ionized gas clumps hosting ultra-compact H II regions found at the edge of the shell suggest that large-scale ionized gas motion triggers the formation of new star generation near the periphery of the shell.

description: Abstract

Mesoophorodiplostomum heckmanni n. sp. infest the small intestine of Bubulcus ibis (Cattle egret). New specimens are similar to  genus species  Mesoophorodiplostomum anterovarium (Dronen, 1985) and Mesoophorodiplostomum pricei (Krull, 1934) Dubois 1936 with respect to general body appearance, but differs in oral sucker size, esophagus, acetabulum, holdfast organ, gonads, vitelline follicles distribution, copulatory bursa evert, and a new host and locality. A new species Mesoophorodiplostomum heckmanni is proposed based on the unique morphotaxonomic features of the present specimens compared to all reported species of the genus Mesoophorodiplostomum. It is the first record for this genus and host Bubulcus ibis (Cattle egret) from Larkana, Sindh, Pakistan.

Στόχος της εργασίας είναι η εκτίμηση της αποδοτικότητας των επιχειρήσεων και η ερμηνεία των παραγόντων επιρροή αυτής. Μέσω της βιβλιογραφίας εντοπίζονται διάφορες προσεγγίσεις μέτρησης της αποτελεσματικότητας στον κλάδο του λιανεμπορίου και σε διάφορα πεδία εφαρμογής που μας βοηθάει να έχουμε μια ολοκληρωμένη άποψη για τον κλάδο. Από τις 147 επιχειρήσεις που εκτιμήθηκαν οι 5 καταλαμβάνουν το 50% περίπου του συνολικού μεριδίου αγοράς, δίνοντας ενδείξεις ολιγοπωλίου. Συμπερασματικά οι επιχειρήσεις που εμφάνισαν υψηλή αποτελεσματικότητα είναι κυρίως επιχειρήσεις μικρές ως προς τον αριθμό των εργαζομένων. Από την ανάλυση των αποτελεσμάτων δεν προκύπτει συσχετισμός ανάμεσα στο μερίδιο αγοράς ως προς τις πωλήσεις και στην τεχνική αποτελεσματικότητα. Γενικά το λιανεμπόριο παρουσιάζει σχετικά σταθερή τεχνική αποτελεσματικότητα με σημείο καμπής το 2004, όπου στην Ελλάδα, έλαβαν χώρα σημαντικά γεγονότα όπως οι Ολυμπιακοί Αγώνες και οι βουλευτικές εκλογές.
description: In this paper, the non-parametric method of linear programming Data Envelopment Analysis is used, to measure the efficiency and compare retailers who are based in Greece. The aim of the study is to assess the effectiveness of firms and interpretation of factors influence the efficiency. Through literature various approaches are identified for measuring efficiency in the retail sector and in various fields of application which helps us to have a comprehensive view on the sector. Of the 147 firms which were assessed, 5 occupy approximately 50% of the total market share, giving evidence of oligopoly. In conclusion, the companies showed high efficiency are mainly small businesses in terms of number of employees. The analysis of the results shows no clear correlation between the share of sales and technical efficiency. In general retail trade presents a relatively stable technical efficiency with a turning point in 2004 where in Greece major events took place like the Olympics and elections.

description: It is our intention to provide via fractional calculus a generalization of the pure and compound Poisson processes, which are known to play a fundamental role in renewal theory, without and with reward, respectively. We first recall the basic renewal theory including its fundamental concepts like waiting time between events, the survival probability, the counting function. If the waiting time is exponentially distributed we have a Poisson process, which is Markovian. However, other waiting time distributions are also relevant in applications, in particular such ones with a fat tail caused by a power law decay of its density. In this context we analyze a non-Markovian renewal process with a waiting time distribution described by the Mittag-Leffler function. This distribution, containing the exponential as particular case, is shown to play a fundamental role in the infinite thinning procedure of a generic renewal process governed by a power asymptotic waiting time. We then consider the renewal theory with reward that implies a random walk subordinated to a renewal process.

description: Rotating outflows from protostellar disks might trace extended magneto-hydrodynamic (MHD) disk winds (DWs), providing a solution to the angular momentum problem in disk accretion for star formation. In the jet system HH 212, a rotating outflow was detected in SO around an episodic jet detected in SiO. Here we spatially resolve this SO outflow into three components: a collimated jet aligned with the SiO jet, the wide-angle disk outflow, and an evacuated cavity in between created by a large jet-driven bowshock. Although it was theoretically predicted before, it is the first time that such a jet-DW interaction is directly observed and resolved, and it is crucial for the proper interpretation and modeling of non-resolved DW candidates. The resolved kinematics and brightness distribution both support the wide-angle outflow to be an extended MHD DW dominating the local angular momentum extraction out to 40 au, but with an inner launching radius truncated to $\gtrsim 4$ au. Inside 4 au, where the DW may not exist, the magneto-rotational instability (MRI) might be transporting angular momentum outwards. The jet-DW interaction in HH 212, potentially present in other similar systems, opens an entirely new avenue to probe the large-scale magnetic field in protostellar disks.

Magnetohydrodynamic Shearing Waves

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I consider the nonaxisymmetric linear theory of a rotating, isothermal magnetohydrodynamic (MHD) shear flow. The analysis is performed in the shearing box, a local model of a thin disk, using a decomposition in terms of shearing waves, i.e., plane waves in a frame comoving with the shear. These waves do not have a definite frequency as in a normal mode decomposition, and numerical integration of a coupled set of amplitude equations is required to characterize their time dependence. Their generic time dependence, however, is oscillatory with slowly-varying frequency and amplitude, and one can construct accurate analytical solutions by applying the Wentzel-Kramers-Brillouin method to the full set of amplitude equations. The solutions have the following properties: 1) Their accuracy increases with wavenumber, so that most perturbations that fit within the disk are well-approximated as modes with time-dependent frequencies and amplitudes. 2) They can be broadly classed as incompressive and compressive perturbations, the former including the nonaxisymmetric extension of magnetorotationally unstable modes, and the latter being the extension of fast and slow modes to a differentially-rotating medium. 3) Wave action is conserved, implying that their energy varies with frequency. 4) Their shear stress is proportional to the slope of their frequency, so that they transport angular momentum outward (inward) when their frequency increases (decreases). The complete set of solutions constitutes a comprehensive linear test suite for numerical MHD algorithms that incorporate a background shear flow. I conclude with a brief discussion of possible astrophysical applications.

Frequency and terrain factors for high-frequency snow avalanche paths
Creators: name: Smith, Michael Johnson
Publisher: name: University of British Columbia
Year: 2009

description: The expected frequency of avalanche events is an essential component of risk in land-use planning and design of avalanche defences in the runout zone. In the past, detailed field studies have been undertaken to determine the frequency of avalanches on individual paths, but there have been few studies to determine the frequency analytically from terrain variables or to determine a probability distribution from which formal risk calculations can be made. In this thesis, I present an analysis based on extensive field measurements for high-frequency avalanche paths (return period less than 30 years). My study focuses on two important aspects: (1) calculation of extreme runout on high-frequency avalanche paths using terrain variables. (2) determination of the probability-density or probability-mass function for high-frequency avalanche paths as an input to risk assessment. By virtue of the extensive database, the work in this thesis represents the most comprehensive study of high-frequency avalanche paths now in existence. The results will find application in land-use planning studies, risk mapping calculations and design of avalanche defences.
An uncertainty principle for star formation -- V. The influence of dust extinction on star formation rate tracer lifetimes and the inferred molecular cloud lifecycle

description: Recent observational studies aiming to quantify the molecular cloud lifecycle require the use of known 'reference time-scales' to turn the relative durations of different phases of the star formation process into absolute time-scales. We previously constrained the characteristic emission time-scales of different star formation rate (SFR) tracers, as a function of the SFR surface density and metallicity. However, we omitted the effects of dust extinction. Here, we extend our suite of SFR tracer emission time-scales by accounting for extinction, using synthetic emission maps of a high-resolution hydrodynamical simulation of an isolated, Milky-Way-like disc galaxy. The stellar feedback included in the simulation is inefficient compared to observations, implying that it represents a limiting case in which the duration of embedded star formation (and the corresponding effect of extinction) is overestimated. Across our experiments, we find that extinction mostly decreases the SFR tracer emission time-scale, changing the time-scales by factors of 0.04-1.74, depending on the gas column density. UV filters are more strongly affected than H$α$ filters. We provide the limiting correction factors as a function of the gas column density and flux sensitivity limit for a wide variety of SFR tracers. Applying these factors to observational characterisations of the molecular cloud lifecycle produces changes that broadly fall within the quoted uncertainties, except at high kpc-scale gas surface densities ($Σ_{\rm g}\gtrsim20~{\mathrm{M_{\odot}\,pc^{-2}}}$). Under those conditions, correcting for extinction may decrease the measured molecular cloud lifetimes and feedback time-scales, which further strengthens previous conclusions that molecular clouds live for a dynamical time and are dispersed by early, pre-supernova feedback.

description: We present Far Ultraviolet Spectroscopic Explorer (FUSE) and Space Telescope Imaging Spectrograph (STIS E140M) observations of the post-asymptotic giant branch star ZNG 1 in the globular cluster Messier 5 (l=3.9, b=+47.7; d=7.5 kpc, z=+5.3 kpc). High velocity absorption is seen in C IV, Si IV, O VI, and lower ionization species at LSR velocities of -140 and -110 km/s. We conclude that this gas is not circumstellar on the basis of photoionization models and path length arguments. Thus, the high velocity gas along the ZNG 1 sight line is the first evidence that highly-ionized HVCs can be found near the Galactic disk. We measure the metallicity of these HVCs to be [O/H]=+0.22\pm0.10, the highest of any known HVC. Given the clouds' metallicity and distance constraints, we conclude that these HVCs have a Galactic origin. This sight line probes gas toward the inner Galaxy, and we discuss the possibility that these HVCs may be related to a Galactic nuclear wind or Galactic fountain circulation in the inner regions of the Milky Way.

description: We report Spitzer Space Telescope photometry between 3.6 microns and 24 microns and spectroscopy between 5 microns and 15 microns of GD 362, a white dwarf with an effective temperature near 10,000 K that displays a remarkably high concentration of metals in its photosphere and a thermal infrared excess. We approximately reproduce both the infrared continuum and the very strong 10 micron silicate emission feature with a model of an orbiting dusty disk which is flat out to 50 stellar radii and warped between 50 and 70 stellar radii. The relatively small amount of cold material implied by the weak 24 mircon flux argues that the disk lies within the Roche radius of the star, and we may be witnessing a system where an asteroidal-size body has been tidally destroyed. If so, determination of the photospheric metal abundances may measure the bulk composition of an extrasolar minor planet.

description: The region of spacetime near the event horizon of a black hole can be viewed as a deep potential well at large gravitational redshift relative to distant observers. However, matter orbiting in this region travels at relativistic speeds and can impart a significant Doppler shift to its electromagnetic emission, sometimes resulting in a net observed blueshift at infinity. Thus, a black hole broadens the line emission from monochromatic sources in its vicinity into a smoothly decaying "red wing"--whose flux vanishes at large redshift--together with a "blue blade" that retains finite flux up to a sharp edge corresponding to the maximum observable blueshift. In this paper, we study the blue blade produced by isotropic monochromatic emitters on circular equatorial orbits around a Kerr black hole, and obtain simple relations describing how the maximum blueshift encodes black hole spin and inclination. We find that small values of the maximum blueshift yield an excellent probe of inclination, while larger values provide strong constraints on spin or inclination in terms of the other. These results bear direct relevance to ongoing and future observations aiming to infer the angular momentum of supermassive black holes from the broadening of their surrounding line emission.

Η θεωρία των Μαρξ και Ένγκελς για την εξέλιξη του πολιτισμού και το ζήτημα της εξουσίας και του κράτους σύμφωνα με τη Γερμανική Ιδεολογία. Η σύγκρουση με την προηγούμενη φιλοσοφική παράδοση:

description: Σκοπός της διπλωματικής εργασίας είναι η ανάλυση της κριτικής των Μαρξ και Ένγκελς στην προηγούμενη γερμανική φιλοσοφική παράδοση, αλλά και η παρουσίαση των βασικών αρχών του ιστορικού υλισμού, έτσι όπως διατυπώνονται για πρώτη φορά στη Γερμανική Ιδεολογία. Η κριτική αποτελεί στην ουσία μία τοποθέτηση απέναντι στη γενική φιλοσοφική κίνηση, η οποία εκφράζεται με αφαιρετικές έννοιες και δημιουργεί την αυταπάτη μιας ορισμένης αυτοκίνησης. Η αφετηρία της Γερμανικής Ιδεολογίας είναι οι πραγματικοί άνθρωποι, τα άτομα και πάνω σ’ αυτή τη βάση οι φιλόσοφοι επεξεργάζονται ένα ιδεώδες ανθρώπου, που έχει απελευθερωθεί από τους πραγματικούς καταναγκασμούς και περιορισμούς, το οποίο και πρέπει να πλησιάσουν. Οι αληθινοί άνθρωποι των Μαρξ και Ένγκελς ζουν κοινωνικά, μέσα στις σχέσεις τους με τους άλλους ανθρώπους και εδώ ακριβώς παρατηρείται η αντικατάσταση με ένα συγκεκριμένο κριτήριο μίας αφηρημένης γενικότητας και αυτό αποτελεί την αληθινή καμπή στη σκέψη των ιδρυτών του μαρξισμού.
description: The aim of the present thesis is the analysis of the critique of Marx and Engels in the previous German philosophical tradition and the presentation of the basic principles of historical materialism as formulated for the first time in German Ideology. The criticism is essentially a general attitude toward philosophical movement, which is expressed by abstract concepts and creates the illusion of a certain automobile. The starting point of German Ideology are the real people and on this basis, the philosophers process an ideal human being that has been released from the real constraints and limitations, and which they should approach. The real people of Marx and Engels live socially within their relations with other people and here exactly is being noticed the replacement of an abstract generality and this is the true turning point in the theory of the founders of Marxism.
The superorbital variability and triple nature of the X-ray source 4U 1820-303

description: We perform a comprehensive analysis of the superorbital modulation in the ultracompact X-ray source 4U 1820-303, consisting of a white dwarf accreting onto a neutron star. Based on RXTE data, we measure the fractional amplitude of the source superorbital variability (with a 170-d quasi-period) in the folded and averaged light curves, and find it to be by a factor of about 2. As proposed before, the superorbital variability can be explained by oscillations of the binary eccentricity. We now present detailed calculations of the eccentricity-dependent flow through the inner Lagrangian point, and find a maximum of the eccentricity of about 0.004 is sufficient to explain the observed fractional amplitude. We then study hierarchical triple models yielding the required quasi-periodic eccentricity oscillations through the Kozai process. We find the resulting theoretical light curves to match well the observed ones. We constrain the ratio of the semimajor axes of the outer and inner systems, the component masses, and the inclination angle between the inner and outer orbits. Last but not least, we discover a remarkable and puzzling synchronization between the observed period of the superorbital variability (equal to the period of the eccentricity oscillations in our model) and the period of the general-relativistic periastron precession of the binary.

Memory-efficient GAN-based Domain Translation of High Resolution 3D Medical Images

description: Generative adversarial networks (GANs) are currently rarely applied on 3D medical images of large size, due to their immense computational demand. The present work proposes a multi-scale patch-based GAN approach for establishing unpaired domain translation by generating 3D medical image volumes of high resolution in a memory-efficient way. The key idea to enable memory-efficient image generation is to first generate a low-resolution version of the image followed by the generation of patches of constant sizes but successively growing resolutions. To avoid patch artifacts and incorporate global information, the patch generation is conditioned on patches from previous resolution scales. Those multi-scale GANs are trained to generate realistically looking images from image sketches in order to perform an unpaired domain translation. This allows to preserve the topology of the test data and generate the appearance of the training domain data. The evaluation of the domain translation scenarios is performed on brain MRIs of size 155x240x240 and thorax CTs of size up to 512x512x512. Compared to common patch-based approaches, the multi-resolution scheme enables better image quality and prevents patch artifacts. Also, it ensures constant GPU memory demand independent from the image size, allowing for the generation of arbitrarily large images.

description: This work is an application of the second order gauge theory for the Lorentz group, where a description of the gravitational interaction is obtained which includes derivatives of the curvature. We analyze the form of the second field strenght, $G=\partial F +fAF$, in terms of geometrical variables. All possible independent Lagrangians constructed with quadratic contractions of $F$ and quadratic contractions of $G$ are analyzed. The equations of motion for a particular Lagrangian, which is analogous to Podolsky's term of his Generalized Electrodynamics, are calculated. The static isotropic solution in the linear approximation was found, exhibiting the regular Newtonian behaviour at short distances as well as a meso-large distance modification.

description: The study of the motion of a rigid body on a plane (RBP motion) is usually one of the most challenging topics that students face in introductory physics courses. In this paper, we discuss a couple of problems which are typically used in basic physics courses, in order to highlight some aspects related to RBP motion which are not usually well understood by physics students. The first problem is a pendulum composed of a rod and disk. The angular frequency of the pendulum is calculated in two situations: disk fixed to the rod and disk free to spin. A detailed explanation of the change in the angular frequency from one case to another is given. The second problem is a ladder which slides touching a frictionless surface. We use this problem to highlight the fact that the contact forces applied by the surface perform translational and rotational work despite that the total mechanical energy of the ladder is conserved.

description: Due to several physical limitations in the realisation of quantum hardware, today's quantum computers are qualified as Noisy Intermediate-Scale Quantum (NISQ) hardware. NISQ hardware is characterized by a small number of qubits (50 to a few hundred) and noisy operations. Moreover, current realisations of superconducting quantum chips do not have the ideal all-to-all connectivity between qubits but rather at most a nearest-neighbour connectivity. All these hardware restrictions add supplementary low-level requirements. They need to be addressed before submitting the quantum circuit to an actual chip. Satisfying these requirements is a tedious task for the programmer. Instead, the task of adapting the quantum circuit to a given hardware is left to the compiler. In this paper, we propose a Hardware-Aware mapping transition algorithm (HA) that takes the calibration data into account with the aim to improve the overall fidelity of the circuit. Evaluation results on IBM quantum hardware show that our HA approach can outperform the state of the art both in terms of the number of additional gates and circuit fidelity.
