description: Η παρούσα ερευνητική εργασία επιχειρεί να διερευνήσει την έννοια της μνήμης ως πρωτογενές στοιχείο της ανθρώπινης νόησης και ύπαρξης μέσα από τις χωρικές της υποστυλώσεις στην ατομική και στη συλλογική σφαίρα. Η εργασία εκκινεί από την διάκριση  του φιλοσόφου Paul Ricoeur, ο οποίος ταξινομώντας τις θεωρητικές παραδόσεις  που εξέτασαν το φαινόμενο της αναμνηστικής λειτουργίας από την αρχαιότητα και έπειτα διέκρινε δύο σχολές: την «παράδοση του εσωτερικού βλέμματος» και εκείνη του «εξωτερικού βλέμματος». Λαμβάνοντας σαν αφετηρία σκέψης αυτή τη διάκριση μελετάται η πόλη και τα μνημεία ως μια «εξωτερική» ανάγνωση της μνήμης για να καταλήξουμε στην «εσωτερική» ή προσωπική ανάγνωση της μνήμης που έχει αποκτήσει ο άνθρωπος στο χώρο του σπιτιού των παιδικών χρόνων. Γίνεται ουσιαστικά μια από τα έξω προς τα μέσα, ή από το γενικό στο ειδικό ανάγνωση των πεδίων της μνήμης που καθορίζουν την ανθρώπινη υπόσταση και το παρόν που βιώνει.
description: This thesis attempts to investigate the meaning of memory as a primary element of human cognition and existence through its spatial aspects in the personal and the collective sphere. The thesis initiates from a distinction the philosopher Paul Ricoeur makes. While investigating the theoretical traditions that examined the function of memory from antiquity onwards, he distinguishes two schools of thought: the “tradition of the inner eye” and the “tradition of the external eye”. Taking this as starting point, the city and the monuments are examined as the “external” memory to arrive to the “inner” memory that individuals acquire in their childhood home. An out-to-inwards or a general-to-specific approach is taken to aspects of memory that determine human condition and the experience of the present.

description: Semantic hashing is an emerging technique for large-scale similarity search based on representing high-dimensional data using similarity-preserving binary codes used for efficient indexing and search. It has recently been shown that variational autoencoders, with Bernoulli latent representations parametrized by neural nets, can be successfully trained to learn such codes in supervised and unsupervised scenarios, improving on more traditional methods thanks to their ability to handle the binary constraints architecturally. However, the scenario where labels are scarce has not been studied yet. This paper investigates the robustness of hashing methods based on variational autoencoders to the lack of supervision, focusing on two semi-supervised approaches currently in use. The first augments the variational autoencoder's training objective to jointly model the distribution over the data and the class labels. The second approach exploits the annotations to define an additional pairwise loss that enforces consistency between the similarity in the code (Hamming) space and the similarity in the label space. Our experiments show that both methods can significantly increase the hash codes' quality. The pairwise approach can exhibit an advantage when the number of labelled points is large. However, we found that this method degrades quickly and loses its advantage when labelled samples decrease. To circumvent this problem, we propose a novel supervision method in which the model uses its label distribution predictions to implement the pairwise objective. Compared to the best baseline, this procedure yields similar performance in fully supervised settings but improves the results significantly when labelled data is scarce. Our code is made publicly available at https://github.com/amacaluso/SSB-VAE.

A proposal for a Bohmian ontology of quantum gravity

Subjects: subject: History and Philosophy of Physics (physics.hist-ph)

description: The paper shows how the Bohmian approach to quantum physics can be applied to develop a clear and coherent ontology of non-perturbative quantum gravity. We suggest retaining discrete objects as the primitive ontology also when it comes to a quantum theory of space-time and therefore focus on loop quantum gravity. We conceive atoms of space, represented in terms of nodes linked by edges in a graph, as the primitive ontology of the theory and show how a non-local law in which a universal and stationary wave-function figures can provide an order of configurations of such atoms of space such that the classical space-time of general relativity is approximated. Although there is as yet no fully worked out physical theory of quantum gravity, we regard the Bohmian approach as setting up a standard that proposals for a serious ontology in this field should meet and as opening up a route for fruitful physical and mathematical investigations.

description: Single-cell RNA-seq (scRNA-seq) analysis is widely used to characterize cell types or detect the heterogeneity of cell states at much higher resolutions than ever before. With the emergence of large-scale data like Human Cell Landscape or Mouse Cell Atlas, there is a growing need for a data mining tool that can swiftly search the data of interest. Here, we introduce scMontage (http://cellblast.stemcellinformatics.org), a gene expression similarity search server dedicated to scRNA-seq data and capable of rapidly comparing a query with thousands of samples within a few seconds. The scMontage search is based on Spearman’s rank correlation coefficient, and its robustness is ensured by introducing Fisher’s Z-transformation and Z-test. Furthermore, search results are linked to the human cell database SHOGoiN (http://shogoin.stemcellinformatics.org), which enables users to quickly access additional cell-type specific information. Although there already exist tools for gene similarity searches, the fast search, easy to use server and no need to normalize the data are distinctive attributes of scMontage. scMontage is available not only as a web server, but also as a stand-alone application for the user’s own data, and thus enhances the reliability and throughput of the cell analysis to help users gain new insights into their research.

description: Patient lives depend on rapid and accurate detection of acute infection status as well as prediction of the severity of their condition. However, conventional clinical measures for these tasks (e.g. physiological symptoms, lab culture results) are suboptimal. Characterizing a patient's immune response from gene expression measurements derived from blood has proven an effective strategy for timely detection of the presence, type and severity of infection in that patient. Developing machine learning classifiers from these gene expression measurements depends, in part, on hyperparameter optimization (HO), a process by which aspects of the classifier related to its training or structure are tuned according to some performance objective. Multiple approaches including grid search, random sampling, and Bayesian optimization have been proposed and proven successful for HO of machine learning classifiers. In general, these approaches have been compared under a limited range of settings and solely with respect to the internal validation performance of the tuned classifier (e.g. in k-fold cross-validation or on a validation set partitioned from the training set). In addition, these approaches have not been evaluated previously for HO of diagnostic classifiers using genomic data. In this comprehensive analysis, we evaluate performance in both internal validation and in a multi-cohort, held-out external validation dataset of multiple types of classifiers selected by three methods for HO (including Bayesian optimization). We evaluate performance on two different classification tasks: 1) multi-class acute infection detection (BVN; Bacterial infection, Viral infection or Noninfected inflammation) and 2) prediction of a mortality event within 30 days of hospital admission. We train and evaluate all classifiers with multi-cohort expression datasets comprising a variety of geographical regions, healthcare settings, and assay platforms. We find that classifiers selected by all three hyperparameter optimization approaches perform comparably but that multi-layer perceptron classifiers of 30-day mortality selected by Bayesian optimization outperform their counterparts selected by other HO approaches. Contrary to previous research, we find evidence in our setting that: 1) Bayesian optimization is not necessarily more efficient in selecting classifiers compared with alternative HO methods and 2) using a common variant of Gaussian process-based Bayesian optimization (i.e. automatic relevance determination) results in only marginal gains in classifier performance.

description: We revisit Ricci dark energy in Chern-Simons modified gravity. As far as the cosmological evolution, this is nothing but the Ricci dark energy with a minimally coupled scalar without potential which means that the role of Chern-Simons term is suppressed. Using the equation of state parameter, this model is similar to the modified Chaplygin gas model only when two are around the de Sitter universe deriving by the cosmological constant in the future. However, two past evolutions are different.

description: This paper considers the problem of symbol detection in massive multiple-input multiple-output (MIMO) wireless communication systems. We consider hard-thresholding preceeded by two variants of the regularized least squares (RLS) decoder; namely the unconstrained RLS and the RLS with box constraint. For all schemes, we focus on the evaluation of the mean squared error (MSE) and the symbol error probability (SEP) for M-ary pulse amplitude modulation (M-PAM) symbols transmitted over a massive MIMO system when the channel is estimated using linear minimum mean squared error (LMMSE) estimator. Under such circumstances, the channel estimation error is Gaussian which allows for the use of the convex Gaussian min-max theorem (CGMT) to derive asymptotic approximations for the MSE and SER when the system dimensions and the coherence duration grow large with the same pace. The obtained expressions are then leveraged to derive the optimal power distribution between pilot and data under a total transmit energy constraint. In addition, we derive an asymptotic approximation of the goodput for all schemes which is then used to jointly optimize the number of training symbols and their associated power. Numerical results are presented to support the accuracy of the theoretical results.

description: Stochastic Taylor expansions of the expectation of functionals applied to diffusion processes which are solutions of stochastic differential equation systems are introduced. Taylor formulas w.r.t. increments of the time are presented for both, Itô and Stratonovich stochastic differential equation systems with multi-dimensional Wiener processes. Due to the very complex formulas arising for higher order expansions, an advantageous graphical representation by coloured trees is developed. The convergence of truncated formulas is analyzed and estimates for the truncation error are calculated. Finally, the stochastic Taylor formulas based on coloured trees turn out to be a generalization of the deterministic Taylor formulas using plain trees as recommended by Butcher for the solutions of ordinary differential equations.

description: We employ tip-enhanced infrared near-field microscopy to study the plasmonic properties of epitaxial quasi-free-standing monolayer graphene on silicon carbide. The near-field images reveal propagating graphene plasmons, as well as a strong plasmon reflection at gaps in the graphene layer, which appear at the steps between the SiC terraces. When the step height is around 1.5 nm, which is two orders of magnitude smaller than the plasmon wavelength, the reflection signal reaches 20% of its value at graphene edges, and it approaches 50% for step heights as small as 5 nm. This intriguing observation is corroborated by numerical simulations, and explained by the accumulation of a line charge at the graphene termination. The associated electromagnetic fields at the graphene termination decay within a few nanometers, thus preventing efficient plasmon transmission across nanoscale gaps. Our work suggests that plasmon propagation in graphene-based circuits can be tailored using extremely compact nanostructures, such as ultra-narrow gaps. It also demonstrates that tip-enhanced near-field microscopy is a powerful contactless tool to examine nanoscale defects in graphene.

description: We give a low temperature formula for the stationary occupations in Markovian systems away from detailed balance. Two applications are discussed, one to determine the direction of the ratchet current and one on population inversion. Both can take advantage of low temperature to improve the gain and typical nonequilibrium features. The new formula brings to the foreground the importance of kinetic aspects in terms of reactivities for deciding the levels with highest occupation and thus gives a detailed quantitative meaning to Landauer's blowtorch theorem at low temperature.

description: The classical Cahn-Hilliard (CH) equation corresponds to a gradient dynamics model that describes phase decomposition in a binary mixture. In the spinodal region, an initially homogeneous state spontaneously decomposes via a large-scale instability into drop, hole or labyrinthine concentration patterns of a typical structure length followed by a continuously ongoing coarsening process. Here we consider the coupled CH dynamics of two concentration fields and show that nonreciprocal (or active, or nonvariational) coupling may induce a small-scale (Turing) instability. At the corresponding primary bifurcation a branch of periodically patterned steady states emerges. Furthermore, there exist localized states that consist of patterned patches coexisting with a homogeneous background. The branches of steady parity-symmetric and parity-asymmetric localized states form a slanted homoclinic snaking structure typical for systems with a conservation law. In contrast to snaking structures in systems with gradient dynamics, here, Hopf instabilities occur at sufficiently large activity which result in oscillating and traveling localized patterns.

description: The bias of an estimator is defined as the difference of its expected value from the parameter to be estimated, where the expectation is with respect to the model. Loosely speaking, small bias reflects the desire that if an experiment is repeated indefinitely then the average of all the resultant estimates will be close to the parameter value that is estimated. The current paper is a review of the still-expanding repository of methods that have been developed to reduce bias in the estimation of parametric models. The review provides a unifying framework where all those methods are seen as attempts to approximate the solution of a simple estimating equation. Of particular focus is the maximum likelihood estimator, which despite being asymptotically unbiased under the usual regularity conditions, has finite-sample bias that can result in significant loss of performance of standard inferential procedures. An informal comparison of the methods is made revealing some useful practical side-effects in the estimation of popular models in practice including: i) shrinkage of the estimators in binomial and multinomial regression models that guarantees finiteness even in cases of data separation where the maximum likelihood estimator is infinite, and ii) inferential benefits for models that require the estimation of dispersion or precision parameters.

description: In this paper, we study the mean square error (MSE) and the bit error rate (BER) performance of the box-relaxation decoder in massive multiple-input-multiple-output (MIMO) systems under the assumptions of imperfect channel state information (CSI) and receive-side channel correlation. Our analysis assumes that the number of transmit and receive antennas ($n$,and $m$) grow simultaneously large while their ratio remains fixed. For simplicity of the analysis, we consider binary phase shift keying (BPSK) modulated signals. The asymptotic approximations of the MSE and BER enable us to derive the optimal power allocation scheme under MSE/BER minimization. Numerical simulations suggest that the asymptotic approximations are accurate even for small $n$ and $m$. They also show the important role of the box constraint in mitigating the so called double descent phenomenon.

description: We present the detection of a rare case of dramatic strengthening in the UV absorption profiles in the spectrum of the quasar J115122.14+020426.3 between observations ~2.86 years apart in the quasar rest-frame. A 2001 spectrum from the Sloan Digital Sky Survey (SDSS) shows a CIV "mini-broad" absorption line (FWHM=1,220 km/s) with a maximum blueshift velocity ~9,520 km/s, while a later spectrum from the Very Large Telescope (VLT) shows significantly broader and stronger absorption line, with a maximum blueshift velocity of ~12,240 km/s, that qualifies as a broad absorption line. A similar variability pattern is observed in two additional systems at lower blueshifted velocities and in the Lya and NV transitions as well. One of the absorption systems appears to be resolved and shows evidence for partial covering of the quasar continuum source (Cf~0.65), indicating a transverse absorber size of, at least, ~6 x 10^(16) cm. In contrast, a cluster of narrower CIV lines appears to originate in gas that fully covers the continuum and broad emission line sources. There is no evidence for changes in the centroid velocity of the absorption troughs. This case suggests that, at least some of the absorbers that produce "mini-broad" and broad absorption lines in quasar spectra do not belong to intrinsically separate classes. Here, the "mini-broad" absorption line is most likely interpreted as an intermediate phase before the appearance of a broad absorption line due to their similar velocity. While the current observations do not provide enough constraints to discern among the possible causes for this variability, future monitoring of multiple transitions at high resolution will help achieve this goal.

description: We are presenting work on recognising acronyms of the form Long-Form (Short-Form) such as "International Monetary Fund (IMF)" in millions of news articles in twenty-two languages, as part of our more general effort to recognise entities and their variants in news text and to use them for the automatic analysis of the news, including the linking of related news across languages. We show how the acronym recognition patterns, initially developed for medical terms, needed to be adapted to the more general news domain and we present evaluation results. We describe our effort to automatically merge the numerous long-form variants referring to the same short-form, while keeping non-related long-forms separate. Finally, we provide extensive statistics on the frequency and the distribution of short-form/long-form pairs across languages.
Dispersion Relation of Longitudinal Waves in Liquid He-4 in the Framework of Quantum Macroscopic Equations derived from Bohm's Potential

description: He-4 is known to become superfluid at very low temperatures. This effect is now generally accepted to be connected with BEC (Bose-Einstein Condensation). The dispersion relation of pressure waves in superfluid He-4 has been determined at 1.1 °K by Yarnell et al., and exhibits a non monotonic behavior - with a maximum and a minimum - usually explained in terms of excitations called rotons, introduced by Landau. In the present work an attempt is made to describe the phenomenon within the bohmian interpretation of QM. To this end, the effects of the intermolecular potential, taken to be essentially of the Lennard-Jones type modified to account for molecule finiteness, are included as a Vlasov-type self-consistent field. A dispersion relation is found, that is in quite good agreement with Yarnell's curve. Keywords: Bohm potential; Intermolecular potential; Dispersion relation; Superfluid He-4; First sound.

description: Diese Arbeit stellt ein Problem des Dauerfestigkeitsversagens von Federn in Kolbenkompressoren vor. Aufgrund von zufälligen Bewegungen des Kompressors, die einem nicht-konstanten, nicht-proportionalem Lastprofil entsprechen, werden fortgeschrittene Methoden der Dauerfestigkeitsanalyse benötigt. Basierend auf verfügbarer Literatur wird das \acf{cpm} ausgewählt, die sich gut für eine Softwareimplementierung eignet. In Kombination mit einer \acf{fem} Spannungsanalyse stellt dies eine gute Basis für eine Dauerfestigkeitsanalyse dar, die auf der lokalen Spannung basiert. Ein objektorientiertes Tool für Dauerfestigkeitsanalyse ist konzeptualisiert und in Python implementiert. Das systematische Testen und Validierung erfolgt mittels Test-Beispielen steigender Komplexität. Ihre klassen- und objektbasierte Struktur ermöglicht zukünftige Erweiterungen der Funktionalität. Schlussendlich werden zwei realitätsnahe Anwendungsbeispiele, eine Kompressor-Kurbelwelle und eine Feder, vorgerechnet, um sowohl eine vereinfachte, als auch eine vollständige Dauerfestigkeitsanalyse zu demonstrieren
description: The present thesis presents a problem of fatigue failure in suspension springs of reciprocating compressors. Due to random displacements that equate to a non-constant, non-proportional loading profile, an advanced fatigue evaluation method is necessary. Based on available literature the \acf{cpm} is chosen for this purpose, being especially well-suited for a software implementation. In conjunction with a \ac{fem} stress analysis it forms a good basis for local stress based fatigue evaluation methods. An object-oriented fatigue tool is conceptualized and subsequently implemented in Python. It is systematically tested and validated on cases of increasing complexity. Its class- and object-based structure enables future extensions of functionality.Finally, real-life use cases of a compressor crankshaft and compressor spring are presented to showcase the use of the tool for a simplified and a full fatigue evaluation process.

description: We say that a pure $d$-dimensional simplicial complex $Δ$ on $n$ vertices is \emph{shelling completable} if $Δ$ can be realized as the initial sequence of some shelling of $Δ_{n-1}^{(d)}$, the $d$-skeleton of the $(n-1)$-dimensional simplex. A well-known conjecture of Simon posits that any shellable complex is shelling completable. In this note we prove that vertex decomposable complexes are shelling completable. In fact we show that if $Δ$ is a vertex decomposable complex then there exists an ordering of its ground set $V$ such that adding the revlex smallest missing $(d+1)$-subset of $V$ results in a complex that is again vertex decomposable. We explore applications to matroids and shifted complexes, as well as connections to ridge-chordal complexes and $k$-decomposability. We also show that if $Δ$ is a $d$-dimensional complex on at most $d+3$ vertices then the notions of shellable, vertex decomposable, shelling completable, and extendably shellable are all equivalent.

description: We have established a relation between the brightest super star cluster magnitude in a galaxy and the host star formation rate (SFR) for the first time in the near infrared (NIR). The data come from a statistical sample of ~ 40 luminous IR galaxies (LIRGs) and starbursts utilizing K-band adaptive optics imaging. While expanding the observed relation to longer wavelengths, less affected by extinction effects, it also pushes to higher SFRs. The relation we find, M_K ~ - 2.6 log SFR, is similar to that derived previously in the optical and at lower SFRs. It does not, however, fit the optical relation with a single optical to NIR color conversion, suggesting systematic extinction and/or age effects. While the relation is broadly consistent with a size-of-sample explanation, we argue physical reasons for the relation are likely as well. In particular, the scatter in the relation is smaller than expected from pure random sampling strongly suggesting physical constraints. We also derive a quantifiable relation tying together cluster-internal effects and host SFR properties to possibly explain the observed brightest SSC magnitude vs. SFR dependency.

description: Clover improvement is the standard choice for lattice simulations of QCD, when the lattice artefacts coming from Wilson fermions have to be reduced. However, the clover improvement is not limited to QCD, but can be applied to a wider range of theories with fermions in higher representations of the gauge group SU(N), like the adjoint fermions required by supersymmetry or by technicolor theories. We present the calculation of the clover coefficient up to one loop order with standard perturbation theory for these models. Applications of clover fermions to supersymmetric Yang-Mills theory are also discussed.

CKNet: A Convolutional Neural Network Based on Koopman Operator for Modeling Latent Dynamics from Pixels

description: With the development of end-to-end control based on deep learning, it is important to study new system modeling techniques to realize dynamics modeling with high-dimensional inputs. In this paper, a novel Koopman-based deep convolutional network, called CKNet, is proposed to identify latent dynamics from raw pixels. CKNet learns an encoder and decoder to play the role of the Koopman eigenfunctions and modes, respectively. The Koopman eigenvalues can be approximated by eigenvalues of the learned state transition matrix. The deterministic convolutional Koopman network (DCKNet) and the variational convolutional Koopman network (VCKNet) are proposed to span some subspace for approximating the Koopman operator respectively. Because CKNet is trained under the constraints of the Koopman theory, the identified latent dynamics is in a linear form and has good interpretability. Besides, the state transition and control matrices are trained as trainable tensors so that the identified dynamics is also time-invariant. We also design an auxiliary weight term for reducing multi-step linearity and prediction losses. Experiments were conducted on two offline trained and four online trained nonlinear forced dynamical systems with continuous action spaces in Gym and Mujoco environment respectively, and the results show that identified dynamics are adequate for approximating the latent dynamics and generating clear images. Especially for offline trained cases, this work confirms CKNet from a novel perspective that we visualize the evolutionary processes of the latent states and the Koopman eigenfunctions with DCKNet and VCKNet separately to each task based on the same episode and results demonstrate that different approaches learn similar features in shapes.
