description: In this work, quasinormal modes (QNMs) of the Schwarzschild black hole are investigated by taking into account the quantum fluctuations. Gravitational and Dirac perturbations were considered for this case. The Regge-Wheeler gauge and the Dirac equation were used to derive the perturbation equations of the gravitational and Dirac fields respectively and the third order Wentzel-Kramers-Brillouin (WKB) approximation method is used for the computing of the quasinormal frequencies. The results show that due to the quantum fluctuations in the background of the Schwarzschild black hole, the QNMs of the black hole damp more slowly when increasing the quantum correction factor (a), and oscillate more slowly.

Applied mathematics not elsewhere classified

description: In this paper, a mathematical model for an extended multi-objective portfolio selection (EMOPS) problem is explored with liquidity considered as another objective function besides the risk and return. The model is mathematically formulated in an uncertain environment. The concerned uncertainty is dealt with by employing the fuzzy numbers in the risk matrix and return. While the fuzzy EMOPS model is converted into the corresponding deterministic case based on the a—level sets of the fuzzy numbers, a weighted Tchebycheff method is implemented by defining relative weights and ideal targets. The merit of the suggested method is the applicability in many real-world situations. At the end, some numerical illustration is exhibited for the utility of the suggested EMOPS problem. Finally, it is concluded that the suggested method is simple to learn and to implement in real-life situations for the decision maker.
[52] Improved YOLOv3-tiny Object Detector with Dilated CNN for Drone-Captured Images.

description: The research problems on Object detection have been attracted with major issues in the computer vision domain. Object detection based on images from unmanned aerial vehicles (UAV) - drones, has versatile applications in both defence security, agriculture and GIS. However, real-time object detection in UAV scenarios remains quite a tedious problem due to environmental obstructions such as occlusion and view-invariant conditions despite the high number of solutions proposed to solve this task. This paper proposes an improved YOLOv3-tiny object detector by introducing a multi-dilated module between the convolution unit and the receptive field, where the problem of a small number of positive training samples is solved by a larger size of the predicted feature map thereby reducing the rate of label rewriting in YOLOv3-tiny. We find that the fusion of multi-scale receptive fields is effective in detecting even every single tiny object. We introduce a path aggregation module that merges the semantic information in a deeper layer and detailed information in an earlier layer. The analysis of the proposed solution shows that on the VisDrone2019-Det test set, our proposed model is more efficient and effective, running 2.96% times faster and increasing 4.0% AP50 than YOLOv3.

Unter der Leitidee „Funktionaler Zusammenhang“ finden sich in den Bildungsstandards nicht nur das Erstellen der einzelnen Darstellungen (Graph, Tabelle, Funktionsterm, Situation), sondern auch die Übersetzung zwischen den Darstellungen und deren Interpretation als anzustrebende Kompetenzen (KMK 2004, S.12). Die inhaltlichen Anforderungen beim Übersetzungsprozess wurden in zahlreichen Studien beschrieben (vgl. Leinhardt et al. 1990). Die vorgelegte Studie konzentriert sich auf zwei Repräsentationsformen von Funktionen - Graph und Tabelle - im Zusammenhang mit Aufgabenstellungen, in denen Funktionen durch Situationen repräsentiert sind.

description: Starting from the consideration of the role that the presence of lists of famous women has played in the complex question of attributing the ‹Caccia di Diana› to Giovanni Boccaccio, this article investigates the possibility that the author was inspired by the French tradition of women's tournaments for the construction of these catalogical sections. In fact, the examination of the few contemporary Italian examples suggests turning the attention to Gallo-Romance models (texts in which the poet, as in the ‹Caccia›, is a witness who gives an account, through poetry, of what he has personally seen): in the last part of this essay is discussed the probability that Boccaccio may actually have known and read these French texts during the years of his stay in Naples.

description: Der Beitrag nimmt ›Die Königin vom Brennenden See‹ in den Blick, die seit 45 Jahren, seit Paul Sapplers Edition 1977, zumeist als bloßes Aufzählungsglied erscheint, wenn man Beispiele für mittelhochdeutsche Feenerzählungen aufsagt. Ziel ist es, nicht nur zur interpretatorischen Erschließung eines hauptsächlich rein nominell präsenten Einzeltextes beizutragen, sondern auf dieser Grundlage auch einige übergreifende Fragehorizonte zu eröffnen, die für andere Texte nach demsel­ben Erzählmuster ebenfalls von Relevanz sein könnten. Einleitend wird eine Poetik der Deeskalation vorgestellt, um einen Einblick in die Machart dieser anonymen Feenerzählung zu gewähren. Sodann gilt es, das ungewöhnliche Berührungs- bzw. Verwundungstabu zu diskutieren: Der Mann darf die ›Fee‹ nicht blutig machen. Die Analyse kreist um die glufe, die Schmucknadel als Requisit des Tabubruchs, die die Frage nach der Rolle von Dingen in der Dramaturgie des Übertritts aufwirft sowie poetologische, wortgeschichtliche und datierungs­technische Überlegungen zusam­menschließt.

description: Recently LIGO collaboration discovered gravitational waves \cite{Abbott_16} predicted 100 years ago by A. Einstein. Moreover, in the key paper reporting about the discovery, the joint LIGO \& VIRGO team presented an upper limit on graviton mass such as $m_g < 1.2 \times 10^{-22} eV$ (Abbott et al. (LIGO collaboration) PRL 116 (2016) 061102). Since the graviton mass limit is so small the authors concluded that their observational data do not show violations of classical general relativity. We consider another opportunity to evaluate a graviton mass from phenomenological consequences of massive gravity and show that an analysis of bright star trajectories could bound graviton mass with a comparable accuracy with accuracies reached with gravitational wave interferometers and expected with forthcoming pulsar timing observations for gravitational wave detection. It gives an opportunity to treat observations of bright stars near the Galactic Center as a wonderful tool not only for an evaluation specific parameters of the black hole but also to obtain constraints on the fundamental gravity law such as a modifications of Newton gravity law in a weak field approximation. In particular, we obtain bounds on a graviton mass based on a potential reconstruction at the Galactic Center.

Deep deformable models for 3D human body
Creators: name: Wang, Haoyang
Publisher: name: Imperial College London
Year: 2020

description: Deformable models are powerful tools for modelling the 3D shape variations for a class of objects. However, currently the application and performance of deformable models for human body are restricted due to the limitations in current 3D datasets, annotations, and the model formulation itself. In this thesis, we address the issue by making the following contributions in the field of 3D human body modelling, monocular reconstruction and data collection/annotation. Firstly, we propose a deep mesh convolutional network based deformable model for 3D human body. We demonstrate the merit of this model in the task of monocular human mesh recovery. While outperforming current state of the art models in mesh recovery accuracy, the model is also light weighted and more flexible as it can be trained end-to-end and fine-tuned for a specific task. A second contribution is a bone level skinned model of 3D human mesh, in which bone modelling and identity-specific variation modelling are decoupled. Such formulation allows the use of mesh convolutional networks for capturing detailed identity specific variations, while explicitly controlling and modelling the pose variations through linear blend skinning with built-in motion constraints. This formulation not only significantly increases the accuracy in 3D human mesh reconstruction, but also facilitates accurate in the wild character animation and retargetting. Finally we present a large scale dataset of over 1.3 million 3D human body scans in daily clothing. The dataset contains over 12 hours of 4D recordings at 30 FPS, consisting of 7566 dynamic sequences of 3D meshes from 4205 subjects. We propose a fast and accurate sequence registration pipeline which facilitates markerless motion capture and automatic dense annotation for the raw scans, leading to automatic synthetic image and annotation generation that boosts the performance for tasks such as monocular human mesh reconstruction.

description: In this paper we develop a cost-benefit analysis of a major research infrastructure, the Large Hadron Collider (LHC), the highest-energy accelerator in the world, currently operating at CERN. We show that the evaluation of benefits can be made quantitative by estimating their welfare effects on different types of agents. Four classes of direct benefits are identified, according to the main social groups involved: (a) scientists; (b) students and young researchers; (c) firms in the procurement chain and other organizations; (d) the general public, including onsite and website visitors and other media users. These benefits are respectively related to the knowledge output of scientists; human capital formation; technological spillovers; and direct cultural effects for the general public. Welfare effects for taxpayers can also be estimated by the contingent valuation of the willingness to pay for a pure public good for which there is no specific direct use (i.e., as non-use value). Using a Monte Carlo approach, we estimate the conditional probability distribution of costs and benefits for the LHC from 1993 until its planned decommissioning in 2025, assuming a range of values for some critical stochastic variables. We conservatively estimate that there is around a 90\% probability that benefits exceed costs, with an expected net present value of about 2.9 billion euro, not considering the unpredictable applications of scientific discovery.

In Silico study of hydrogel adhesives
Creators: name: Xie, Kaiye
Publisher: name: Imperial College London

description: Adhesion is defined as the process of joining two dissimilar surfaces together so that they can resist separation. Adhesives can be in various physical forms including liquid, film, powder etc. In the last three decades, adhesives and adhesion phenomena in biomedical applications have been the subject of intensive studies and rapid developments, because of their significance in many scenarios, e.g., wound dressing and implant installations. Due to the wet and corrosive environment of human fluids, achieving good adhesion while maintaining good biocompatibility is never an easy task. Usually bioadhesives are in the form of polymeric glue or patch. Besides, taking inspirations from nanoparticle incorporated in polymer network to enhance composites' mechanical properties, solutions of nanoparticles have recently been introduced as a new type of bioadhesive. Robust bioadhesives already exist, and some of them are commercialised for clinical use. However, they are far from ideal. Each type of currently available bioadhesive has its own limitations. In most cases, the microscopic mechanism of adhesion and the adhesive behaviour during mechanical deformation is still unclear. Thanks to the rapidly developing computational powers of modern computers, more and more simulation work can now be used to understand how these mechanisms can lead to more robust performance, aiming at further improvement. By using a molecular simulation approach, I have investigated both polymer and nanoparticle based adhesive to glue hydrogels, carrying out parametric studies and optimisations. In particular, after discussing the literature on adhesion in Chapter 1 and the general methodology in Chapter 2, in Chapter 3 I study polymer based glues for hydrogels, looking at how their architecture affects their gluing power. In Chapter 4, I switch to adhesive patches, where polymer chains are not in solutions but rather grafted onto a crosslinked polymer matrix, and look at the effect on adhesion of both chains and the matrix structure, as well as their interactions with the hydrogel. In Chapter 5, I address the case of nanoparticle based glues, looking at how their size, shape and their mutual interactions and their interactions with the gel, affect their overall adhesive behaviours. Finally, in Chapter 6, I summarise all previous work, and provide potential directions for future work based on the results obtained so far.

description: This paper proposes a deteriorating inventorymodel with random demand with shortages. Shortages are permitted and treated as to be fully backlogged. Deterioration rate is constant. Demand of the items is a nonstop irregular variable, which pursues the uniform likelihood dispersion. Based on these assumptions, a mathematical model for the optimization of average total cost (ATC) function of the problem is formulated. Two numerical examples are presented. The convexity of the average total cost function is verified graphically. To measure the flexibility of the present model; the post-optimal analysis is applied by changing parameters.

description: Motivated by the recent discovery of quantized spin Hall effect in InAs/GaSb quantum wells\cite{du2013}$^,$\cite{xu2014}, we theoretically study the effects of in-plane magnetic field and strain effect to the quantization of charge conductance by using Landauer-Butikker formalism. Our theory predicts a robustness of the conductance quantization against the magnetic field up to a very high field of 20 tesla. We use a disordered hopping term to model the strain and show that the strain may help the quantization of the conductance. Relevance to the experiments will be discussed.

description: Unimodular gravity is an alternative theory of gravity to general relativity. The gravitational field equations are given by the trace-free version of Einstein's field equations. Due to the structure of the theory, unimodular gravity admits a diffusion term that characterizes a possible non-conservation of the canonical energy-momentum tensor locally. Employing this feature of unimodular gravity, in the present work, we explicitly show how to construct an inflationary phase that can be contrasted with current observations. In particular, we focus on three different inflationary scenarios of physical interest. An important element in these scenarios is that the accelerated expansion is driven by the diffusion term exclusively, i.e. there is no inflaton. Furthermore, the primordial spectrum during inflation is generated by considering inhomogeneous perturbations associated to standard hydrodynamical matter (modeled as a single ultra-relativistic fluid). For each of the scenarios, we obtain the prediction for the primordial spectrum and contrast it with recent observational bounds.

Flow of colloidal solids and fluids through constrictions: dynamical density functional theory versus simulation

description: Using both dynamical density functional theory and particle-resolved Brownian dynamics simulations, we explore the flow of two-dimensional colloidal solids and fluids driven through a linear channel with a geometric constriction. The flow is generated by a constant external force acting on all colloids. The initial configuration is equilibrated in the absence of flow and then the external force is switched on instantaneously. Upon starting the flow, we observe four different scenarios: a complete blockade, a monotonic decay to a constant particle flux (typical for a fluid), a damped oscillatory behaviour in the particle flux, and a long-lived stop-and-go behaviour in the flow (typical for a solid). The dynamical density functional theory describes all four situations but predicts infinitely long undamped oscillations in the flow which are always damped in the simulations. We attribute the mechanisms of the underlying stop-and-go flow to symmetry conditions on the flowing solid. Our predictions are verifiable in real-space experiments on magnetic colloidal monolayers which are driven through structured microchannels and can be exploited to steer the flow throughput in microfluidics.

description: Fractions EAF and FLB7 (50 μg/mL) reduced the bacterial adhesion of Pg to KB cells significantly (63 resp. 70%). The proanthocyanidin samarangenin A inhibited the adhesion (72%, 30 μM), samarangenin B (71%, 20 μM), and the flavan-3-ol epigallocatechin-3-O-gallate (79%, 30 μM). Fraction AQF, representing hydrophilic compounds, reduced the proteolytic activity of Arginin-specific gingipain (IC50 12.78 μg/mL). Fractions EAF and FLB7, characterized by lipohilic constituents, inhibited Arg-gingipain (IC50 3 μg/mL). On Lysine-specific gingipain, AQF has an IC50 15.89 µg/mL, EAF 14.15 µg/mL and FLB7 6 µg/mL. The reduced bacterial adhesion is due to a strong interaction of proanthocyanidins with gingipains. AQF, EAF and FLB7 significantly inhibited biofilm formation: IC50 11.34 µg/mL (AQF), 11.66 µg/mL (EAF), 12.09 µg/mL (FLB7).

description: A number of important transport networks, such as the airline and trade networks of the world, exhibit a characteristic core-periphery structure, wherein a few nodes are highly interconnected and the rest of the network frays into a tree. Mechanisms underlying the emergence of core-peripheries, however, remain elusive. Here, we demonstrate that a simple pruning process based on removal of underutilized links and redistribution of loads can lead to the emergence of core-peripheries. Links are assumed beneficial if they either carry a sufficiently large load or are essential for global connectivity. This incentivized redistribution process is controlled by a single parameter which balances connectivity and profit. The obtained networks exhibit a highly resilient and connected core with a frayed periphery. The balanced network shows a higher resilience than the World Airline Network or the World Trade Network, revealing a pathway towards robust structural features through pruning.

description: Several supernovae (SNe) with an unusually dense circumstellar medium (CSM) have been recently observed at radio frequencies. Their radio emission is powered by relativistic electrons that can be either accelerated at the SN shock (primaries) or injected as a by-product (secondaries) of inelastic proton-proton collisions. We investigate the radio signatures from secondary electrons, by detailing a semi-analytical model to calculate the temporal evolution of the distributions of protons, primary and secondary electrons. With our formalism, we track the cooling history of all the particles that have been injected into the emission region up to a given time, and calculate the resulting radio spectra and light curves. For a SN shock propagating through the progenitor wind, we find that secondary electrons control the early radio signatures, but their contribution decays faster than that of primary electrons. This results in a flattening of the light curve at a given radio frequency that depends only upon the radial profiles of the CSM density and of the shock velocity, $v_0$. The relevant transition time at the peak frequency is $\sim 190 \, K_{\rm ep,-3}^{-1} A_{\rm w, 16} β_{0, -1.5}^{-2}\,{\rm d}$, where $A_{\rm w}$ is the wind mass-loading parameter, $β_0=v_0/c$ and $K_{\rm ep}$ is the electron-to-proton ratio of accelerated particles. We explicitly show that late peak times at 5 GHz (i.e., $t_{\rm pk} \gtrsim 300-1000$ d) suggest a shock wave propagating in a dense wind ($A_{\rm w} \gtrsim 10^{16}-10^{17}$ gr cm$^{-1}$), where secondary electrons are likely to power the observed peak emission.

description: We present a limited extent single-server lining model with triangular, trapezoidal and hexagonal fuzzy numbers separately. The entry rate and overhauled rate are fuzzy in description, and the arithmetic of interval numbers is enforced. The execution proportions are fuzzified and after that assessed by utilizing α-cut and DSW (Dong, Shah and Wong) calculation. Relating to each sort of fuzzy number, the numerical precedent is encapsulated to check the achievability of this miniature. A comparative investigation relative to individual fuzzy numbers is accomplished for various estimations of α.
The Idiosyncrasy of Preferences Across Domains

Subjects: subject: interrater agreement

subject: variance component analysis

description: There has been much research in the realm of the social sciences in investigating the construction of preferences. However, there is a gap in the literature that examines the stability of our preferences and the idiosyncratic components of preferences within different stimuli domains. Within the current study, the reliability-sharedness of preferences is examined through judgments across different stimulus domains: money gambles, abstract artwork, and faces. Raters in Study 1 were asked to rate 42 money gambles and 42 face stimuli twice on a scale of “Not at all attractive” to “Very attractive”. Using Pearson correlations and variance component analysis, the study found that within both domains, preferences tended to be stable. However, the gamble domain was more likely to have shared preferences among the raters than the face domain, where raters had both individual and shared components. Raters in Study 2 were asked to rate 42 money gambles and 42 abstract artworks twice on a scale of “Not at all attractive” to “Very attractive.” Using the same methods as done in Study 1, the study found that preferences tended to be stable, though artwork preference reliability was lower than the other two domains. The gamble stimuli results remained consistent to Study 1, but artwork VCA found that preferences tended to be much more individualized than the other domains.
Temporal network structures controlling disease spreading

description: We investigate disease spreading on eight empirical data sets of human contacts (mostly proximity networks recording who is close to whom, at what time). We compare three levels of representations of these data sets: temporal networks, static networks and a fully connected topology. We notice that the difference between the static and fully-connected networks -- with respect to time to extinction and average outbreak size -- is smaller than between the temporal and static topologies. This suggests that, for these data sets, temporal structures influence disease spreading more than static network structures. To explain the details in the differences between the representations, we use 32 network measures. This study concur that long-time temporal structures, like the turnover of nodes and links, are the most important for the spreading dynamics.

[21] On Optimizing Neutrosophic Complex Programming Using Lexicographic Order.

description: Neutrosophic sets are considered as a generalization of the crisp set, fuzzy set, and intuitionistic fuzzy set for representing the uncertainty, inconsistency, and incomplete knowledge about the real world problems. This paper aims to characterize the solution of complex programming (CP) problem with imprecise data instead of its prices information. The neutrosophic complex programming (NCP) problem is considered by incorporating single valued trapezoidal neutrosophic numbers in all the parameters of objective function and constraints. The score function corresponding to the neutrosophic number is used to transform the problem into the corresponding crisp CP. Here, lexicographic order is applied for the comparison between any two complex numbers. The comparison is developed between the real and imaginary parts separately. Through this manner, the CP problem is divided into two real sub-problems. In the last, a numerical example is solved for the illustration that shows the applicability of the proposed approach. The advantage of this approach is more flexible and makes a real-world situation more realistic.

Reversibly switchable electromagnetic device with leakage-free electrolyte

description: Electrical control of oxygen off-stoichiometry of transition-metal oxides at room temperature is a desired strategy to simultaneously switch the electrical conductance and magnetism of the device. Although the use of the electrochemical redox reaction of transition-metal oxides is the most reasonable way to achieve the aforementioned switch, such a device has not been realized because of the lack of a leakage-free liquid electrolyte. Here, we demonstrate an electromagnetic device that can reversibly switch a transition-metal oxide from an insulator/non-magnet to a metal/magnet (Tc=275 K) using a newly developed 'leakage-free electrolyte', incorporated in an amorphous NaTaO3 nanopillar array film. Reversible switching occurs electrically, obeying Faraday's laws of electrolysis, under a DC voltage of +(-)3 V within 2-3 s at RT. The present electromagnetic device does not have the drawback of liquid leakage, and the leakage-free electrolyte provides a novel design concept for practical electromagnetic devices using transition-metal oxides.
