description: The Ricci iteration is a discrete analogue of the Ricci flow. We give the first study of the Ricci iteration on a class of Riemannian manifolds that are not Kähler. The Ricci iteration in the non-Kähler setting exhibits new phenomena. Among them is the existence of so-called ancient Ricci iterations. As we show, these are closely related to ancient Ricci flows and provide the first nontrivial examples of Riemannian metrics to which the Ricci operator can be applied infinitely many times. In some of the cases we study, these ancient Ricci iterations emerge (in the Gromov--Hausdorff topology) from a collapsed Einstein metric and converge smoothly to a second Einstein metric. In the case of compact homogeneous spaces with maximal isotropy, we prove a relative compactness result that excludes collapsing.

description: We present WikiReading, a large-scale natural language understanding task and publicly-available dataset with 18 million instances. The task is to predict textual values from the structured knowledge base Wikidata by reading the text of the corresponding Wikipedia articles. The task contains a rich variety of challenging classification and extraction sub-tasks, making it well-suited for end-to-end models such as deep neural networks (DNNs). We compare various state-of-the-art DNN-based architectures for document classification, information extraction, and question answering. We find that models supporting a rich answer space, such as word or character sequences, perform best. Our best-performing model, a word-level sequence to sequence model with a mechanism to copy out-of-vocabulary words, obtains an accuracy of 71.8%.

Three-day-old rats were injected (s.c.) with 5 doses (saline, Zn, Cu or Zn+Cu) for 5 consecutive days and were killed 24 h after the last dose. In the other experiment, 7-day-old rats received only 1 dose (saline, Zn or Cu) and were killed at 1, 6 or 24 h after. For the in vitro experiments, the acetylcholinesterase activity from cerebrum of 8-day-old rats was analyzed in presence of Zn or Cu (0.01 to 1 mM). Regarding the in vivo experiments, only body weight gain was decreased by 5 simultaneous administrations of Zn and Cu. The acetylcholinesterase activity from cerebrum and cerebellum and cerebral zinc and copper contents were not altered by the treatments. In vitro, Cu 0.1 and 1 mM, but not Zn, inhibited the enzyme of both cerebrum and cerebellum. The enzymatic activity from cerebrum and cerebellum homogenate was more sensitive to Cu than the enzymatic activity from S2 and S1 fractions, respectively, since less metal was necessary to inhibit the enzyme.

What to Expect When You Are Expecting on the Grassmannian

description: Consider an incoming sequence of vectors, all belonging to an unknown subspace $\operatorname{S}$, and each with many missing entries. In order to estimate $\operatorname{S}$, it is common to partition the data into blocks and iteratively update the estimate of $\operatorname{S}$ with each new incoming measurement block. In this paper, we investigate a rather basic question: Is it possible to identify $\operatorname{S}$ by averaging the column span of the partially observed incoming measurement blocks on the Grassmannian? We show that in general the span of the incoming blocks is in fact a biased estimator of $\operatorname{S}$ when data suffers from erasures, and we find an upper bound for this bias. We reach this conclusion by examining the defining optimization program for the Fréchet expectation on the Grassmannian, and with the aid of a sharp perturbation bound and standard large deviation results.

description: Zu Beginn dieser Arbeit wurde die Bedeutung der Neutrinoastronomie und die Verbindung zu anderen Gebieten der Astroteilchenphysik verdeutlicht. Der IceCube- Detektor, mit dem diese Arbeit ermöglicht wurde, wurde diskutiert. Auch wurde das Detektionsproblem erläutert, welches auf den niedrigen Wirkungsquerschnitt zwischen Neutrinos und Materie und dem hohen Untergrund zurückzuführen ist. Es wurden weiterhin Methoden des maschinellen Lernens vorgestellt, welche in der Lage sind das Problem des hohen Untergrunds zu überwinden. Diese Methoden wurden auf die Daten des IC 79-Datensatzes angewandt und es konnte ein hochreiner Datensatz an Myon-Neutrinos erzeugt werden. Mit Hilfe neu entwickelter Validierungsmethoden wurde der verbleibende Untergrund untersucht. Es konnte gezeigt werden, dass der verbleibende Untergrund niederenergetisch ist. Bei der Analyse des Datensatzes zeigt sich ein deutlicher Überschuss an Neutrinos bei sehr hohen rekonstruierten Myonenergien. Bei näherer Untersuchung konnte gezeigt werden, dass dieser Untergrund keine typischen Untergrund-Eigenschaft aufweist. Er liegt weder am Rande des Detektors, noch kommt er aus Richtung des Horizonts. Dadurch ist eine Erklärung des Überschusses ausgeschlossen. Mit der Methode der Entfaltung wurde eine Möglichkeit aufgezeigt, aus diesem Datensatz ein Spektrum in der Neutrinoenergie zu berechnen, obwohl die Neutrinoenergie nicht direkt messbar ist. Diese Methode wurde auf den zuvor erstellten Datensatz angewandt und es zeigt sich, dass auch in der Neutrinoenergie ein deutlicher Überschuss oberhalb von 100 TeV zu beobachten ist. Die erzielten Ergebnisse wurden mit anderen Messungen verglichen. Die Messungen im Bereich der atmosphärischen Neutrinokomponente sind kompatibel mit vorherigen Messungen. Die Ergebnisse oberhalb von 100 TeV sind nicht durch konventionelle atmosphärische Neutrinos zu erklären. Die Anpassung und der statistische Test über einen Likelihood-Quotienten-Test ergibt, dass es höchst- wahrscheinlich eine astrophysikalische Komponente gibt. Die Siginifikanz dieser Aussage ist abhängig davon, wie hoch die Normierung der prompten Komponente ist. Mit der Annahme aus [ERS08] ergibt sich eine Signfikanz von 6.65 , dass der gemessene Datensatz nicht irdischen Ursprungs ist.

description: Massive particles with self interactions of the order of 0.2 barn/GeV are intriguing Dark Matter candidates from an astrophysical point of view. Current and past experiments for direct detection of massive Dark Matter particles are focusing to relatively low cross sections with ordinary matter, however they cannot rule out very large cross sections, $σ/M > 0.01$ barn/GeV, due to atmosphere and material shielding. Cosmology places a strong indirect limit for the presence of large interactions among Dark Matter and baryons in the Universe, however such a limit cannot rule out the existence of a small sub-dominant component of Dark Matter with non negligible interactions with ordinary matter in our galactic halo. Here, the possibility of the existence of bound states with ordinary matter, for a similar Dark Matter candidate with not negligible interactions, is considered. The existence of bound states, with binding energy larger than $\sim$1 meV, would offer the possibility to test in laboratory capture cross sections of the order of a barn (or larger). The signature of the detection for a mass increasing of cryogenic samples, due to the possible particle accumulation, would allow the investigation of these Dark Matter candidates with mass up to the GUT scale. A proof of concept for a possible detection set-up and the evaluation of some noise sources are described.

Non-perturbative guiding center and stochastic gyrocenter transformations: gyro-phase is the Kaluza-Klein 5^th dimension also for reconciling General Relativity with Quantum Mechanics

Subjects: subject: General Physics (physics.gen-ph)

description: The non perturbative guiding center transformation is extended to the relativistic regime and takes into account electromagnetic fluctuations. The main solutions are obtained in covariant form: the gyrating particle and the guiding particle solutions, both in gyro-kinetic as in MHD orderings. Moreover, the presence of a gravitational field is also considered. The way to introduce the gravitational field is original and based on the Einstein conjecture on the feasibility to extend the general relativity theory to include electromagnetism by geometry, if applied to the extended phase space. In gyro-kinetic theory, some interesting novelties appear in a natural way, such as the exactness of the conservation of a magnetic moment, or the fact that the gyro-phase is treated as the non observable fifth dimension of the \emph{Kaluza-Klein} model. Electrodynamic becomes non local, without the inconsistency of self-energy. Finally, the gyrocenter transformation is considered in the presence of stochastic e.m. fluctuations for explaining quantum behaviors via Nelson's approach. The gyrocenter law of motion is the \emph{Schrödinger} equation.

description: Ischemic Heart Disease (IHD) is a major cause of death. Early and accurate detection of IHD along with rapid diagnosis are important for reducing the mortality rate. Magnetocardiogram (MCG) is a tool for detecting electro-physiological activity of the myocardium. MCG is a fully non-contact method, which avoids the problems of skin-electrode contact in the Electrocardiogram (ECG) method. However, the interpretation of MCG recordings is time-consuming and requires analysis by an expert. Therefore, we propose the use of machine learning for identification of IHD patients. Back-propagation neural network (BPNN), the Bayesian neural network (BNN), the probabilistic neural network (PNN) and the support vector machine (SVM) were applied to develop classification models for identifying IHD patients. MCG data was acquired by sequential measurement, above the torso, of the magnetic field emitted by the myocardium using a J-T interval of 125 cases. The training and validation data of 74 cases employed 10-fold cross-validation methods to optimize support vector machine and neural network parameters. The predictive performance was assessed on the testing data of 51 cases using the following metrics: accuracy, sensitivity, and specificity and area under the receiver operating characteristic (ROC) curve. The results demonstrated that both BPNN and BNN displayed the highest and the same level of accuracy at 78.43 %. Furthermore, the decision threshold and the area under the ROC curve was -0.2774 and 0.9059, respectively, for BPNN and 0.0470 and 0.8495, respectively, for BNN. This indicated that BPNN was the best classification model, BNN was the best performing model with sensitivity of 96.65 %, and SVM employing the radial basis function kernel displayed the highest specificity of 86.36 %.

description: Bioactivities of thiotetrahydropyridines were previously described. Herein, a novel bioactive sulfoxide analog; N-acetyl-2-(1-adamantylsulfoxo)-3-acetoxy-4-phenyl-6-hydroxy-1,2,3,6-tetrahydropyridine (3) from the deoxydative substitution of 4-phenylpyridine 1-oxide is reported. Its structure was elucidated using spectral data including 2D-NMR, MS, IR and UV. The sulfoxide 3 exhibited antibacterial activity against Moraxella catarrhalis and Streptococcus pyogenes with minimum inhibitory concentration of 128 and 256 μg/mL, respectively.

description: During its first observing run, in late 2015, the advanced LIGO facility announced 3 gravitational wave (GW) triggers to electromagnetic follow-up partners. Two of these have since been confirmed as being of astrophysical origin: both are binary black hole mergers at ~500 Mpc; the other trigger was later found not to be astrophysical. In this paper we report on the Swift follow up observations of the second and third triggers, including details of 21 X-ray sources detected; none of which can be associated with the GW event. We also consider the challenges that the next GW observing run will bring as the sensitivity and hence typical distance of GW events will increase. We discuss how to effectively use galaxy catalogues to prioritise areas for follow up, especially in the presence of distance estimates from the GW data. We also consider two galaxy catalogues and suggest that the high completeness at larger distances of the 2MASS Photometric Redshift Catalogue (2MPZ) makes it very well suited to optimise Swift follow-up observations.

description: Swimming at low Reynolds number in Newtonian fluids is only possible through non-reciprocal body deformations due to the kinematic reversibility of the Stokes equations. We consider here a model swimmer consisting of two linked spheres, wherein one sphere is rigid and the other an incompressible neo-Hookean solid. The two spheres are connected by a rod which changes its length periodically. We show that the deformations of the body are non-reciprocal despite the reversible actuation and hence, the elastic two-sphere swimmer propels forward. Our results indicate that even weak elastic deformations of a body can affect locomotion and may be exploited in designing artificial microswimmers.

description: The outcomes of research in the field of application of high pressure in a process engineering are stated. The high pressure is created by impulsive sources of energy, such as explosion of condensed explosive substances and gaseous detonatable mixtures. Application of high pressure created by explosion for technological processes of sheet forming parts from metal and non-metal materials is considered. In the latter case, the mechanical properties in the process polymerisation of composite materials in the outcome of the impulsive loading significantly rise. The impulsive high pressure has a significant impact on handling - compressing of powder materials, on manufacture of special products, foundry forms and ont destruction of rods in molten products.

description: The scope of this deliverable is to develop a technical implementation which the federated EGA nodes need to become operative within the Federated EGA network. We have created a solution that enables sharing sensitive genetic data with associated or related metadata. The underlying problem is that sensitive genetic data has to be stored safely according to GDPR law and in some instances cannot move across borders (depending on different interpretations of GDPR), while public metadata can. The chosen solution allows files to be stored encrypted in the Local EGAs located in different countries, while public metadata is hosted at Central EGA. We have produced and made public a reference implementation and extensive documentation, to help the nodes set up their Local EGA.
title: Boǧaz’in Rusları: 1920’li Yıllarda Beyoğlu’ndaki Rus Göçmen Sanatçılar
Creators: name: Aygün, Ekaterina

description: Existing literature on Russian-speaking émigré artists in Constantinople in the 1920s is mostly based on three sources: almanac Farewell, almanac Les Russes sur le Bosphore [Russians on the Bosporus] and Jak Deleon’s essays. Being far from thorough, the information from these three sources has been “roaming” from one study to another for quite a long time. It has now turned out however, that the almanacs are not wholly reliable due to their insufficient systematization and the absence of some artists’ full names in the texts. As the research brought to light, this caused a wrong indication of some émigré artists from the former Russian Empire in Istanbul as the Union of Russian Painters in Constantinople’s members. For the same reasons, instead of Vladimir/Wladimir Ivanoff, Vasily Ivanov was wrongly known as the chairman of the Union. For this and other reasons, Ekaterina Aygün attempted to investigate the topic with the help of sources that haven’t been previously touched upon, and which could shed more light on the issue, primarily periodicals in Russian language published in Istanbul in the 1920s and archival material from Stearns Family Papers (The College of the Holy Cross, Worcester, MA). The article answers the following questions: How did “Russian” artists make a living from their art in exile? Did they work together or every artist for himself? How were they occupied after the formation of the Turkish Republic in 1923? Who supported them, and finally, why did they decide to work in Beyoğlu and not in some other district of the city?

description: Artificial Intelligence (AI), characterized as machines replicating "cognitive" functions akin to human thought processes, has witnessed a surge in prominence, notably outlined in the book "Artificial Intelligence: A Modern Approach (AIMA)" by Russell and Norvig (2020). The application of AI in India has witnessed a substantial rise, prompting increased investment in AI research and development across various industries. PwC India's study (PriceWaterhouseCoopers Private Limited India, 2020) reveals that, amidst the global pandemic, India has experienced the highest surge in AI usage, with a remarkable 45% increase compared to developed nations like the US, UK, and Japan.

This research delves into the confluence of AI adoption and electronic retail channels in India, a burgeoning economy offering significant opportunities for e-retailers. The technological advancements and the widespread reach of the internet have paved the way for the expansion of electronic retail channels. The study recognizes the unique circumstances during the pandemic, where Internet shopping has become a vital avenue for consumers, providing enhanced flexibility, interactivity, customization, and low-risk options.

The research aims to elucidate the symbiotic relationship between AI penetration and the evolution of electronic retail channels in the Indian context. By exploring the factors influencing this dynamic interaction, the study seeks to provide insights into the strategic considerations for businesses navigating the landscape of AI-driven e-retail in India.

description: We study a nanofabricated silicon rod levitated in an optical trap. By manipulating the polarization of the light we gain full control over the ro-translational dynamics of the rod. We are able to trap both its centre-of-mass and align it along the linear polarization of the laser field. The rod can be set into rotation at a tuned frequency by exploiting the radiation pressure exerted by elliptically polarized light. The rotational motion of the rod dynamically modifies the optical potential, which allows tuning of the rotational frequency over hundreds of Kilohertz. This ability to trap and control the motion and alignment of nanoparticles opens up the field of rotational optomechanics, rotational ground state cooling and the study of rotational thermodynamics in the underdamped regime.
