Rock art recording in Khatm al Melaha (United Arab Emirates): Multirange data scanning and web mapping technologies

The application of geometric recording data and representation of open-air rock art is intrinsically so heterogeneous that new online web platforms are required for a more efficient analysis to link all the geo-referenced information and facilitate its scientific study. From 2015 to 2018, three geometric documentation campaigns led by the Departamento de Ingeniería Topográfica y Cartografía of the Universidad Politécnica de Madrid (Spain) were completed in the area of Khatm al Melaha (Emirate of Sharjah, United Arab Emirates) along the Gulf of Oman. More than 370 rock art engraved motifs were documented in this area close to the southwest border with the Sultanate of Oman. All those figures were picked in 149 stone blocks with different dimensions and morphologies, distributed along the slope of an isolated 58-meter-high elevation. The aim of this project was to establish a protocol for the recording, analysis, preservation and prevention of this set of open-air rock art engravings with the following actions: developing an aerial and terrestrial recording data documentation, creating and developing a web platform called threeDcloud for visualizing three-dimensional models and web mapping, and integrating a data base by means of different JavaScript open-source libraries

Cell size distribution in a random tessellation of space governed by the Kolmogorov-Johnson-Mehl-Avrami model: Grain size distribution in crystallization

The space subdivision in cells resulting from a process of random nucleation and growth is a subject of interest in many scientific fields. In this paper, we deduce the expected value and variance of these distributions while assuming that the space subdivision process is in accordance with the premises of the Kolmogorov-Johnson-Mehl-Avrami model. We have not imposed restrictions on the time dependency of nucleation and growth rates. We have also developed an approximate analytical cell size probability density function. Finally, we have applied our approach to the distributions resulting from solid phase crystallization under isochronal heating conditions

Análisis comparativo de la atención de pacientes con enfermedad neurológica en el servicio de urgencias hospitalario durante el periodo de confinamiento por COVID-19

El nuevo coronavirus (SARS-CoV-2) fue identificado por primera vez en la ciudad china de Wuhan, en diciembre de 2019. Desde entonces el virus se ha propagado a más de 200 países. El 30 de enero de 2020 el brote fue declarado “Emergencia de salud pública de importancia internacional” por la Organización Mundial de la Salud, y el 11 de marzo elevado a “Pandemia internacional”1. El primer diagnóstico en España se registró el 31 de enero, pero no fue hasta marzo cuando los casos comenzaron a crecer exponencialmente. El 14 de marzo el Gobierno de España declaraba el estado de alarma por el que limitaba la libre circulación de personas, entre otras medidas. En Aragón esta limitación estuvo vigente hasta el 4 de mayo, cuando dio comienzo el proceso de desescalada. A fecha de 16 de junio de 2020 se han confirmado en España 244.328 diagnósticos por test de reacción en cadena de polimerasa (PCR)2. En nuestro hospital, a medida que aumentaba la carga asistencial de enfermedad respiratoria en el servicio de urgencias hospitalarias (SUH), se percibía un descenso del resto de enfermedades, incluida la neurológica y, particularmente, la enfermedad cerebrovascular aguda, como se ha reportado en otros estudios3. A nivel mundial, las enfermedades neurológicas representan la causa principal de años de vida perdidos ajustados por discapacidad y la segunda causa de muerte4. En España, la mortalidad por causa neurológica representa el 19% del total anual. Esta cifra se ha incrementado en los últimos 10 años en un 18, 5%. En el caso de Aragón, las enfermedades neurológicas causan el 20, 6% de las muertes5..

Experimental observation of the amplitude death effect in two coupled nonlinear oscillators

The amplitude death phenomenon has been experimentally observed with a pair of thermo-optical oscillators linearly coupled by heat transfer. A parametric analysis has been done and compared with numerical simulations of a time delayed model. The role of the coupling strength is also discussed from experimental and numerical results

Epidemiología y características del ictus isquémico en el adulto joven en Aragón

Introducción Alrededor de 15 millones de personas sufren un ictus cada año, de los que un 10-15% ocurre en menores de 50 años (ictus en el adulto joven). La prevalencia de los distintos factores de riesgo vascular y las estrategias sanitarias para el manejo del ictus varían a nivel mundial, siendo interesante conocer la epidemiología y las características específicas de cada región. El objetivo de este estudio fue determinar la prevalencia de los diferentes factores de riesgo vascular, la etiología y las características de los ictus isquémicos en el adulto joven en la comunidad autónoma de Aragón. Métodos Estudio multicéntrico, de corte transversal, realizado por los Servicios de Neurología de todos los hospitales del Servicio Aragonés de Salud (SALUD). Se identificó a todos los pacientes entre 18 y 50 años que ingresaron en cualquiera de estos hospitales con el diagnóstico de ictus isquémico o AIT entre enero del 2005 y diciembre del 2015. Se recogieron variables demográficas, factores de riesgo vascular y tipo de ictus isquémico entre otras. Resultados En el periodo de estudio, 786 pacientes entre 18 y 50 años ingresaron con el diagnóstico de ictus isquémico o AIT en algún hospital del SALUD, con una tasa anual promedio de 12, 3 por 100.000 habitantes. La mediana de su edad fue de 45 años (RIQ: 40-48 años). El factor de riesgo vascular más prevalente fue el tabaquismo, 404 (51, 4%). La mayoría fue de causa indeterminada (36, 2%), seguida por «otras causas» (26, 5%). La mediana de puntuación en la escala NIHSS fue de 3, 5 (RIQ: 2, 07, 0). En total, 211 (26, 8%) de los ingresos fueron por AIT. De los pacientes que ingresaron con el diagnóstico de ictus isquémico, 59 (10, 3%) se fibrinolizaron. Conclusiones El ictus isquémico en el adulto joven no es infrecuente en Aragón y en un importante número de casos es de etiología indeterminada, por lo que es necesario implementar medidas que nos permitan mejorar su estudio, disminuir su incidencia y prevenir su recurrencia. Introduction: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. Methods: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. Results: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. Conclusions: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence

Morphometric analysis of engravings from photogrammetric point cloud data

Simple photogrammetric data capture methods and equipment are able to measure accurate dense point clouds and detailed high geometric quality Digital Surface Models (DSMs) can be generated out of them. These products are frequently applied to the recording of rock art. However, their potential is not just limited to documentation and their use can be extended to perform analytic tasks. This paper describes the authors’ first experiments in the morphometric analysis of an engraved surface (an epigraph), based on a DSM generated from photogrammetric data. Slope and curvature models were derived from this DSM and used to identify and extract some structural features of the carvings, much in the same way as topographic landscape features can be identified on a terrain DEM

DESIGN AND DEVELOPMENT OF A LOW–COST AERIAL MOBILE MAPPING SYSTEM FOR MULTI-PURPOSE APPLICATIONS

The research project with the working title "Design and development of a low-cost modular Aerial Mobile Mapping System" was formed during the last year as the result from numerous discussions and considerations with colleagues from the HafenCity University Hamburg, Department Geomatics. The aim of the project is to design a sensor platform which can be embedded preferentially on an UAV, but also can be integrated on any adaptable vehicle. The system should perform a direct scanning of surfaces with a laser scanner and supported through sensors for determining the position and attitude of the platform. The modular design allows his extension with other sensors such as multispectral cameras, digital cameras or multiple cameras systems
