Archaeological Landscape

The potential of large-scale, non-invasive prospection methods has been widely recognized in archaeology in recent years. Their outstanding possibilities for the exploration of urban centres have been realised early on and applied at selected sites. The ‘ArchPro Carnuntum’ project stands out for its extensive investigation of a Roman provincial capital by the combined application of a wide variety of survey methods (aerial archaeology, magnetometry, ground penetrating radar, extensive field survey) resulting in detailed information on the ancient infrastructure of the Roman metropolis. Within the project, it was not only possible to discover new settlement areas, but in some cases even to deduce their former purpose. As a result, the military administrative centre, newly built residential areas, and temporary military camps could be detected in the archaeological landscape of Carnuntum. This paper presents an overview of the results of this internationally unique prospection project.Az elmúlt évek során széles körben felismerték a régészet tudományterületén alkalmazható nagyszabású, nem invazív jellegű kutatási módszerekben rejlő potenciált. A módszer települési központok feltárásának területén alkalmazható lehetőségei már korán valósággá váltak, és alkalmazásra kerültek a kiválasztott helyszíneken. Az „ArchPro Carnuntum” projekt a római provinciális főváros átfogó vizsgálatával a legkülönfélébb felmérési módszerek (légi régészet, magnetometria, földradar, kiterjedt terepi felmérés) együttes alkalmazásával kiemelkedik ezek közül, és részletes információval szolgál a római város antik infrastruktúrájával kapcsolatban. A projekt során nem kizárólag új települési területek felfedezésére nyílt mód, hanem egyes esetekben következtetni lehetett a területek egykori funkciójára is. Mindezek eredményeként a carnuntumi régészeti területen kimutathatóvá vált a katonai igazgatási központ, valamint az új építésű lakónegyedek és az ideiglenes katonai táborhelyek is. Jelen tanulmány ezen nemzetközi szinten is egyedülálló kutatási projekt eredményeiről nyújt áttekintést.

The University

In recent years there has been an increase in the knowledge of, and need for, non-invasive monitoring of ballast in order to identify the problematic sections of track and decrease the maintenance cost. Various technologies such as Ground Penetrating Radar (GPR) are becoming accepted for investigating the condition of ballast. However since these techniques were not originally developed for engineering applications, their applicability in ballast evaluations can be sometimes uncertain. Continued empirical studies and condition specific calibrations are needed to demonstrate repeatable and quantifiable results. In this study large-scale track models with trapezoidal section area were constructed at the University of Massachusetts to investigate the effects of breakdown fouling, and the effects of changing geotechnical properties on GPR traces. This paper presents the design and construction of large scale track models, and methods used for GPR data collection. GPR data are presented in this paper that demonstrate sensitivity to the track model properties and variables. In particular, the experiments are being used to evaluate changes in GPR data with changing geotechnical properties of the ballast such as density, water content, grain size distribution (GSD), and fouling percentage.

Geophysical survey and other non-invasive methods are, in some cases, the only options available for archaeological investigation. This is exemplified at the Collins site, a possible Late Woodland to Middle Mississippian period, multi-mound, civic ceremonial center in Northwest Arkansas. The site is located on private property and although excavation is not allowed, non-invasive survey methods are permitted on its northern section. This paper presents the results of a ground-penetrating radar survey over Mounds B, C, and D. The results reveal a number of features that are interpreted as mortuary structures as well as evidence of multiple building episodes over time within distinct layers of Mound C. A high-resolution DEM generated with aerial imagery is used in interpreting the GPR data as well as to provide an updated map of mound size and distribution. By integrating the GPR data with the DEM, orthoimagery, and magnetic gradiometry data from a previously documented survey, and comparing the results to ethnohistoric accounts, interpretation of the geophysical data is enhanced. Geophysical survey is often used to assess an archaeological site on a landscape scale. By narrowing the scope to individual mounds, this article demonstrates how multiple, complementary technologies, when used in concert, can inform on the feature level.

The Impact

Sophisticated techniques of archaeological survey, including airborne imaging spectroscopy, electromagnetic induction and ground-penetrating radar, are opening up new horizons in the non-invasive exploration of archaeological sites. One location where they have yielded spectacular results is Carnuntum in Austria, on the south bank of the Danube, capital of the key Roman province of Pannonia. Excavations in the late nineteenth and twentieth centuries revealed many of the major elements of this extensive complex, including the legionary fortress and the civilian town or municipium. Excavation, however, is no longer the only way of recovering and recording the details of these buried structures. In 2011, a combination of non-invasive survey methods in the area to the south of the civilian town, where little was visible on the surface, led to the dramatic discovery of remains interpreted as a gladiatorial school, complete with individual cells for the gladiators and a circular training arena. The combination of techniques has led to the recording and visualisation of the buried remains in astonishing detail, and the impact of the discovery is made all the greater by the stunning reconstruction images that the project has generated.

The success of the Program of housing stock renovation in Moscow depends on the efficiency of resource management. One of the main urban planning documents that determine the nature of the reorganization of residential areas included in the Program of renovation is the territory planning project. The implementation of the planning project is a complex process that has a time point of its beginning and end, and also includes a set of interdependent parallel-sequential activities. From an organizational point of view, it is convenient to use network planning and management methods for project implementation. These methods are based on the construction of network models, including its varieties – a Gantt chart. A special application has been developed to simulate the implementation of planning projects. The article describes the basic principles and elements of modeling. The list of the main implementation parameters of the Program of renovation obtained with the help of the developed software for modeling is presented. The variants of using the results obtained for a comprehensive analysis of the implementation of large-scale urban projects are proposed.

AbstractSimilarity in T-cell receptor (TCR) sequences implies shared antigen specificity between receptors, and could be used to discover novel therapeutic targets. However, existing methods that cluster T-cell receptor sequences by similarity are computationally inefficient, making them impractical to use on the ever-expanding datasets of the immune repertoire. Here, we developed GIANA (Geometric Isometry-based TCR AligNment Algorithm) a computationally efficient tool for this task that provides the same level of clustering specificity as TCRdist at 600 times its speed, and without sacrificing accuracy. GIANA also allows the rapid query of large reference cohorts within minutes. Using GIANA to cluster large-scale TCR datasets provides candidate disease-specific receptors, and provides a new solution to repertoire classification. Querying unseen TCR-seq samples against an existing reference differentiates samples from patients across various cohorts associated with cancer, infectious and autoimmune disease. Our results demonstrate how GIANA could be used as the basis for a TCR-based non-invasive multi-disease diagnostic platform.

Mountain Disasters

Climate change increases the frequency of localized heavy rains and typhoons. As a result, mountain disasters, such as landslides and earthworks, continue to occur, causing damage to roads and residential areas downstream. Moreover, large-scale civil engineering works, including dam construction, cause rapid changes in the terrain, which harm the stability of residential areas. Disasters, such as landslides and earthenware, occur extensively, and there are limitations in the field of investigation; thus, there are many studies being conducted to model terrain geometrically and to observe changes in terrain according to external factors. However, conventional topography methods are expressed in a way that can only be interpreted by people with specialized knowledge. Therefore, there is a lack of consideration for three-dimensional visualization that helps non-experts understand. We need a way to express changes in terrain in real time and to make it intuitive for non-experts to understand. In conventional height-based terrain modeling and simulation, there is a problem in which some of the sampled data are irregularly distorted and do not show the exact terrain shape. The proposed method utilizes a hierarchical vertex cohesion map to correct inaccurately modeled terrain caused by uniform height sampling, and to compensate for geometric errors using Hausdorff distances, while not considering only the elevation difference of the terrain. The mesh reconstruction, which triangulates the three-vertex placed at each location and makes it the smallest unit of 3D model data, can be done at high speed on graphics processing units (GPUs). Our experiments confirm that it is possible to express changes in terrain accurately and quickly compared with existing methods. These functions can improve the sustainability of residential spaces by predicting the damage caused by mountainous disasters or civil engineering works around the city and make it easy for non-experts to understand.

Dynamic Relationships

AbstractSpontaneous neural activity fluctuations have been shown to influence trial-by-trial variation in perceptual, cognitive, and behavioral outcomes. However, the complex electrophysiological mechanisms by which these fluctuations shape stimulus-evoked neural activity remain largely to be explored. Employing a large-scale magnetoencephalographic dataset and an electroencephalographic replication dataset, we investigate the relationship between spontaneous and evoked neural activity across a range of electrophysiological variables. We observe that for high-frequency activity, high pre-stimulus amplitudes lead to greater evoked desynchronization, while for low frequencies, high pre-stimulus amplitudes induce larger degrees of event-related synchronization. We further decompose electrophysiological power into oscillatory and scale-free components, demonstrating different patterns of spontaneous-evoked correlation for each component. Finally, we find correlations between spontaneous and evoked time-domain electrophysiological signals. Overall, we demonstrate that the dynamics of multiple electrophysiological variables exhibit distinct relationships between their spontaneous and evoked activity, a result which carries implications for experimental design and analysis in non-invasive electrophysiology.
