Abstract:
AbstractImage and video processing based on geometric principles typically changes the rectangular shape of video frames to an irregular shape. This paper presents a warping based approach for rectangling such irregular frame boundaries in space and time, i.e., making them rectangular again. To reduce geometric distortion in the rectangling process, we employ content-preserving deformation of a mesh grid with line structures as constraints to warp the frames. To conform to the original inter-frame motion, we keep feature trajectory distribution as constraints during motion compensation to ensure stability after warping the frames. Such spatially and temporally optimized warps enable the output of regular rectangular boundaries for the video frames with low geometric distortion and jitter. Our experiments demonstrate that our approach can generate plausible video rectangling results in a variety of applications.

Abstract:
Contrast maximization (CMax) is a framework that provides state-of-the-art results on several event-based computer vision tasks, such as ego-motion or optical flow estimation. However, it may suffer from a problem called event collapse, which is an undesired solution where events are warped into too few pixels. As prior works have largely ignored the issue or proposed workarounds, it is imperative to analyze this phenomenon in detail. Our work demonstrates event collapse in its simplest form and proposes collapse metrics by using first principles of space–time deformation based on differential geometry and physics. We experimentally show on publicly available datasets that the proposed metrics mitigate event collapse and do not harm well-posed warps. To the best of our knowledge, regularizers based on the proposed metrics are the only effective solution against event collapse in the experimental settings considered, compared with other methods. We hope that this work inspires further research to tackle more complex warp models.

Abstract:
Abstract With the increasing popularity of hand-held devices, location-based applications and services have access to accurate and real-time location information, raising serious privacy concerns for their users. The recently introduced notion of geo-indistinguishability tries to address this problem by adapting the well-known concept of differential privacy to the area of location-based systems. Although geo-indistinguishability presents various appealing aspects, it has the problem of treating space in a uniform way, imposing the addition of the same amount of noise everywhere on the map. In this paper we propose a novel elastic distinguishability metric that warps the geometrical distance, capturing the different degrees of density of each area. As a consequence, the obtained mechanism adapts the level of noise while achieving the same degree of privacy everywhere. We also show how such an elastic metric can easily incorporate the concept of a “geographic fence” that is commonly employed to protect the highly recurrent locations of a user, such as his home or work. We perform an extensive evaluation of our technique by building an elastic metric for Paris’ wide metropolitan area, using semantic information from the OpenStreetMap database. We compare the resulting mechanism against the Planar Laplace mechanism satisfying standard geo-indistinguishability, using two real-world datasets from the Gowalla and Brightkite location-based social networks. The results show that the elastic mechanism adapts well to the semantics of each area, adjusting the noise as we move outside the city center, hence offering better overall privacy.1

Abstract:
Dynamic patterns are characterized by complex spatial and motion patterns. Understanding dynamic patterns requires a disentangled representational model that separates the factorial components. A commonly used model for dynamic patterns is the state space model, where the state evolves over time according to a transition model and the state generates the observed image frames according to an emission model. To model the motions explicitly, it is natural for the model to be based on the motions or the displacement fields of the pixels. Thus in the emission model, we let the hidden state generate the displacement field, which warps the trackable component in the previous image frame to generate the next frame while adding a simultaneously emitted residual image to account for the change that cannot be explained by the deformation. The warping of the previous image is about the trackable part of the change of image frame, while the residual image is about the intrackable part of the image. We use a maximum likelihood algorithm to learn the model parameters that iterates between inferring latent noise vectors that drive the transition model and updating the parameters given the inferred latent vectors. Meanwhile we adopt a regularization term to penalize the norms of the residual images to encourage the model to explain the change of image frames by trackable motion. Unlike existing methods on dynamic patterns, we learn our model in unsupervised setting without ground truth displacement fields or optical flows. In addition, our model defines a notion of intrackability by the separation of warped component and residual component in each image frame. We show that our method can synthesize realistic dynamic pattern, and disentangling appearance, trackable and intrackable motions. The learned models can be useful for motion transfer, and it is natural to adopt it to define and measure intrackability of a dynamic pattern.

A superluminal motion (hypermotion) via M. Alcubierre’s warp drive is considered. Parameters of the warp drive have been estimated. The equations of starship geodesics have been solved. The starship velocity have been shown to exceed the speed of light, with the local velocity relative to the deformed space-time being below it. Hawking’s radiation does not prove to affect the ship interior considerably. Difficulties related to a practical realization of the hypermotion are indicated.

The characteristic is that the utilization of resources have the characteristics of time and space warp from both the view points of depth space resource of the time concept of time-point, the time concept of time-point circulation and circulation of point-to-point in one hand, and also breadth space resource of the short-term periodic time cycle, medium-time periodic time cycle and long-time periodic cycle in the other.

Abstract:
Background: Quantitative evaluation of antibiotic spectrum is an important, underutilized metric in measuring antibiotic use (AU) and may assist antimicrobial stewards in identifying targets and strategy for intervention. We evaluated the spectrum of initial antibiotic choices by hospital location, day of the week, and time of day to determine whether these factors may be associated with broad-spectrum antibiotic choices. Methods: We identified all admissions with antibiotic exposure in medical and surgical wards and critical care units in a tertiary academic medical center between July 1, 2014, and July 1, 2019. The antibiotic spectrum index (ASI), proposed by Gerber et al, is a numeric score based on the number of pathogens covered by a particular agent. We defined ASI for initial antibiotic choice as follows: ASI for each unique antibiotic administered within 24 hours of the first antibiotic administration was summed and assigned to the administration time of the first dose. We categorized time into 4 distinct categories: weekday days (Monday–Friday, 7 a.m.–7 p.m.), weekday nights, weekend days, and weekend nights. Weekend time began 7 p.m. Friday and ended 7 a.m. Monday. We constructed heatmaps stratified by hospital location. Mann-Whitney U tests were applied to evaluate differences in the distributions of ASI using weekday days as a reference. Results: Data included 90,455 unique antibiotic admissions with initial antibiotic starts in medical and surgical wards and critical care units. Patterns of ASI for initial antibiotic choice varied between unit locations and time (Figs. 1 and 2). Mean and median ASIs for initial antibiotic choices were higher for medical ward and medical ICUs than for surgical wards and surgical ICUs. Initial antibiotic choices had higher ASIs during overnight hours for all units except the surgical ICU. Notable differences in ASIs were identified between weekday and weekend prescribing for surgical units, whereas medical units demonstrated less extreme differences. Conclusion: We observed a “weekend effect” across hospital units; the most extreme occurred in surgical wards. This observation may be due to differences in patient volume and rounding patterns. For example, hospitalist and critical care units have 7-day schedules, whereas surgical wards are highly influenced by operating room schedules. Antimicrobial stewardship teams may use these data to identify strategies targeting the most opportune time and place to intervene on the spectrum of initial antibiotic choice.Funding: NoneDisclosures: None

Abstract:
ABSTRACT Gaia has revealed clear evidence of bending waves in the vertical kinematics of stars in the solar neighbourhood. We study bending waves in two simulations, one warped, with the warp due to misaligned gas inflow, and the other unwarped. We find slow, retrograde bending waves in both models, with the ones in the warped model having larger amplitudes. We also find fast, prograde bending waves. Prograde bending waves in the unwarped model are very weak, in agreement with the expectation that these waves should decay on short, approximately crossing, time-scales, due to strong winding. However, prograde bending waves are much stronger for the duration of the warped model, pointing to irregular gas inflow along the warp as a continuous source of excitation. We demonstrate that large-amplitude bending waves that propagate through the solar neighbourhood give rise to a correlation between the mean vertical velocity and the angular momentum, with a slope consistent with that found by Gaia. The bending waves affect populations of all ages, but the sharpest features are found in the young populations, hinting that short-wavelength waves are not supported by the older, kinematically hotter, populations. Our results demonstrate the importance of misaligned gas accretion as a recurrent source of vertical perturbations of disc galaxies, including in the Milky Way.

Abstract:
Cellular space modeling is becoming an increasingly important modeling paradigm for modeling complex systems with spatial-temporal behaviors. The growing demand for cellular space models has directed researchers to use different modeling formalisms, among which Discrete Event System Specification (DEVS) is widely used due to its formal modeling and simulation framework. The increasing complexity of systems to be modeled asks for cellular space models with large number of cells for modeling the systems¡¯ spatial-temporal behavior. Improving simulation performance becomes crucial for simulating large scale cellular space models. In this dissertation, we proposed a framework for improving simulation performance for large scale DEVS-based cellular space models. The framework has a layered structure, which includes modeling, simulation, and network layers corresponding to the DEVS-based modeling and simulation architecture. Based on this framework, we developed methods at each layer to overcome performance issues for simulating large scale cellular space models. Specifically, to increase the runtime and memory efficiency for simulating large number of cells, we applied Dynamic Structure DEVS (DSDEVS) to cellular space modeling and carried out comprehensive performance measurement. DSDEVS improves simulation performance by making the simulation focus only on those active models, and thus be more efficient than when the entire cellular space is loaded. To reduce the number of simulation cycles caused by extensive message passing among cells, we developed a pre-schedule modeling approach that exploits the model behavior for improving simulation performance. At the network layer, we developed a modified time-warp algorithm that supports parallel simulation of DEVS-based cellular space models. The developed methods have been applied to large scale wildfire spread simulations based on the DEVS-FIRE simulation environment and have achieved significant performance results.

Abstract:
Central to a number of films made during or about the First World War is a thinned relationship between the living and the dead. The Battle of the Somme (1916) depicts a moment in which, from a row of soldiers going over the top, two slip back, shot. Their dying, or death, occurs between frames, an aperture through which the viewer may glimpse another dimension. J’Accuse (1919, 1938) employs soon-to-die soldiers as extras in a sequence in which the dead return. The result is a fantastical crossing between living and dead. In Pour la Paix du Monde (1926), soldiers whose faces have been maimed by war injuries are seen first in close-up, their mutilations covered by silken masks. Then they tear the masks off, allowing the viewer to see the war in its ‘true colours’. Affording the viewer these glimpses of the after-life, all three films create imaginative warps in space-time.

Abstract:
In recent years, the need for a temporal dimension in traditional spatial information systems and for high-level models useful for the conceptual design of the resulting spatiotemporal systems has become clear. Although having in common a need to manage spatial data and their changes over time, various spatiotemporal applications may manage different types of spatiotemporal data and may be based on very different models of space, time, and change. For example, the term spatiotemporal data is used to refer both to temporal changes in spatial extents, such as redrawing the boundaries of a voting precinct or land deed, and to changes in the value of thematic (i.e., alphanumeric) data across time or space, such as variation in soil acidity measurements depending on the measurement location and date. A spatiotemporal application may be concerned with either or both types of data. This, in turn, is likely to influence the underlying model of space employed, e.g., the two types of spatiotemporal data generally correspond to an object- versus a field-based spatial model. For either type of spatiotemporal data, change may occur in discrete steps, e.g., changes in land deed boundaries, or in a continuous process, e.g., changes in the position of a moving object such as a car. Another type of spatiotemporal data is composite data whose components vary depending on time or location. An example is the minimum combination of equipment and wards required in a certain category of hospital (e.g., general, maternity, psychiatric), where the relevant regulations determining the applicable base standards vary by locality and time period.

Abstract:
Ontology is integral to the two most fundamental scientific theories of the twentieth century: quantum theory and the special and general theories of relativity. Issues that drove the development of quantum theory include the reality of quanta, the simultaneous wave- and particle-like nature of matter and energy, determinism, probability and randomness, Schrodinger’s wave equation, and Heisenberg’s uncertainty principle. So did the reality of the predictions about space, time, matter, energy, and the universe itself that were deduced from the special and general theories of relativity. Dirac’s prediction of antimatter based solely on the mathematics of his theory of the electron and Pauli’s prediction of the neutrino based on his belief in quantum mechanics are cases in point. Ontological interpretations of the uncertainty principle, of quantum vacuum energy fields, and of Schrodinger’s probability waves in the form of multiple universe theories further illustrate this point.

Abstract:
Like Bacon, Descartes, and Galileo, Newton identified method as the key to discovering truths about the world, and like theirs, Newton’s method conflated induction and deduction in making claims about reality. Against Robert Hooke, Newton claimed that data spoke for themselves, as in his claim that his prism experiments directly proved that sunlight really was a combination of colors. In his theory of light, Newton claimed that his data allowed him to “deduce” that light was made up of corpuscles, against Christiaan Huygens’ claim that light was composed of spherical waves. In Newton’s mechanics, which became the cornerstone of modern mathematical physics, neither his definitions of space, time, matter, and motion nor his famous three laws of motion were deduced from experimental data. In his dismissal of Descartes’ method of reasoning and in his battles with Leibniz over the nature of reality, Newton was forced to confront the logical weakness of his ontological claims.

Abstract:
Chapter 6 examines the various ways in which the Bakhtinian heteroglossia of epic performances has been created: by the use of a participating bardic figure, who extends the Brechtian role of narrator/commentator to assume agency within both the fictional and actual worlds of the spectators; by their space-time settings; and by both their live-ness in, and their aliveness to, the immediate performance context. Since the time of the Modernists, led by Joyce and Woolf in Britain and Oswaldo de Andrade in Brazil, epic has begun to be re-envisioned; rather than a genre in which to retell the heroic narratives of a nation, it has become a place where the voices of those previously overshadowed and neglected are finally given space. Derek Walcott’s The Odyssey: A Stage Version, Suzan-Lori Parks’ Father Comes Home from the Wars, and Lisa Petersen and Denis O’Hare’s An Iliad each do this in different ways, giving voice to those whose narratives were occluded in the ancient epics.

This article is a first attempt to elaborate a Hispanic reading and relocation of Europe and modernity in an Atlantic space/time that is neither European nor modern, and can be denominated Atlantic transmodernity (Dussel). The goal is not to refashion a more problematic Europe and modernity, even in a postcolonial fashion, by provincializing it (Chakrabarty), but rather to create a new geopolitical space, the Hispanic Atlantic, and a temporality, an Atlantic transmodernity, that turns the idea of Europe/modernity into an ideological effect produced by the geopolitics of the Atlantic. In order to do so, the article concentrates, on the one hand, on 19th-century Spanish history of the state of exception, and, on the other, on the not-so-well known history of the inception of the concentration camp in Cuba between 1896 and 1898.

The paper outlines some phenomena that may influence the popularity of saints’ names in Christian societies. The diachronic overview focuses on the Hungarian given name stock and its changes and alternations in time, space and society. The multidisciplinary approach is mainly based on historical and onomastic literature and large databases of given names from the Middle Ages to modern days. Among the religious factors, the study presents the impact of religious taboos, the interference between cults of saints of the same name, and the collective veneration of saints. Political factors are also introduced: the effects of the Reformation, Catholic Revival, and wars against the Ottoman Empire in the 16th–18th centuries.

Abstract:
Authentic public memorials did not appear in the Chinese public space until the late 19th century. As a result of Western influence, many war memorials were built during the Republic of China era (1912-1949). Since the establishment of the People’s Republic of China in 1949, the government has invested much in developing public spaces. Also, the government placed many memorials in Chinese cities to shape collective memory and urban identity. The affection of solemnness, sacredness, and grandness is the main affection that most memorials are intended to embody, particularly those that commemorate famous people, the government’s achievement, and the deceased from natural disasters and wars. By taking the example of memorials built from 1942 to the present in Chongqing, China, this paper critically examines changes over time in the forms. In addition, taking the analysis result from memorial forms as a base and combining widely cited literature in Chinese and English, the paper further explores the negative impacts of the intensive focus of solemnness, sacredness, and grandness. This paper’s analysis identifies standard, persistent and symbolic features in Chinese memorials, despite the diverse landscape elements and advanced construction techniques. Key themes emerge from this research are solemnness, sacredness, and grandness. Also, it reveals the issues raised by the exclusive pursuit of these affections, including similar memorial forms, insufficient engagement of memorials, and the unitary research topics on memorials.

Abstract:
With the popularity of video games, more and more researchers are trying to understand the relationship between video game activity and cognitive abilities, and one of the important cognitive systems is working memory. Working memory is a limited capacity short-term memory system for processing currently active information and is an important predictor of goal-driven behavioral domains. Its scope of action includes, but is not limited to, fluid intelligence, verbal ability, and mathematical analysis.Due to the importance of working memory for the analysis of human behavior, numerous studies have attempted to describe the architecture and models of working memory. In general, models of working memory can be loosely categorized into content and process models, depending on their focus. The content model focuses on the static material of working memory, which includes mainly verbal and spatial visual material. The process model focuses on the dynamic processes of working memory and includes both Updating and Maintenance of memory.However, this area of research has also been the subject of debate among researchers.Translated with www.DeepL.com/Translator (free version). These disputes involve two main assumptions. According to the so-called core training hypothesis, a potential machine for improving cognitive ability through video games is provided by the so-called core training hypothesis. According to this hypothesis, repeated stress on the cognitive system will induce plastic changes in its neural matrix, leading to improved cognitive response performance. According to this hypothesis, repeated strains of the cognitive system can induce plastic changes in its neural matrix, which is an important reason for the improvement of performance. The other proposed basic mechanism is the meta-learning mechanism, that is, learning how to learn. According to this, video games (especially action games) can improve related motor control skills, such as rule learning, cognitive resource allocation, and probabilistic reasoning skills, which are used in many different situations.A recent study showed that the analysis of certain extreme groups showed that video game players performed better than non-game players in all three WM measurements, and that when extended to the entire sample, video game time and visual space WM and n-back performance. In general, the relationship between cognition and playing video games is very weak.This study used the Waris et al, 2019 dataset to re-investigate the correlation between video game activity and three different dimensions of working memory using seven different supervising learning models. It was concluded that video game activity was most highly correlated with the visuospatial component, slightly less correlated with the mnemonic updating component, and least correlated with the verbal component. This partly confirms Waris et al, 2019's view that the analytic method may be the key to the study.
