Un modelo ontológico para la representación del Carnaval de Barranquilla como patrimonio cultural en un sistema consciente al contexto

The Barranquilla Carnival is the most important cultural expression of Colombia, declared as Oral and Intangible Cultural Heritage of Humanity by UNESCO in 2003. This paper proposes an ontological model for the management of the Carnival of Barranquilla as a measure of recognition worldwide in a context-aware system. The ontological model has 18 domains that relate the Barranquilla Carnival (Traditional Dances, Device, Environment, Dance Schools, Cultural Event, Cultural Managers, Interface, Location, Profile, People, Typical Characters, Typical Food, Preference, Network, Cultural Sites, Time and Clothing), evaluated by means of seven (7) situations that were described in natural language and SWRL (this language was used because it allows expressing concepts in OWL combined with RuleML). The proposed model can be used in other similar cultural expressions such as the Binche Carnival in Belgium, the Basel Carnival in Switzerland, the Oruro Carnival in Bolivia, the Recife Carnival in Brazil, the Podence Carnival in Portugal, among others that enjoy the recognition of cultural and intangible heritage of humanity.El carnaval de Barranquilla es la expresión cultural más importante de Colombia, declarado como Patrimonio Cultural oral e Inmaterial de la Humanidad por la UNESCO en el año 2003. En este documento se propone un modelo ontológico para la gestión del Carnaval de Barranquilla como medida de reconocimiento a nivel mundial en un sistema consciente al contexto. El modelo ontológico cuenta con 18 dominios que relacionan el Carnaval de Barranquilla (Danzas Tradicionales, Dispositivo, Entorno, Escuelas de danzas, Evento Cultural, Gestores culturales, Interfaz, Localización, Perfil, Personas, Personajes típicos, Comidas típicas, Preferencia, Red, Sitios Culturales, Tiempo y Vestimenta), evaluado por medio de siete (7) situaciones que fueron descritas en lenguaje natural y SWRL (Se usó este lenguaje porque permite expresar conceptos en OWL combinado con RuleML). El modelo propuesto se puede usar en otras expresiones culturales similares como es el caso del Carnaval de Binche en Bélgica, el Carnaval de Basilea en Suiza, Carnaval de Oruro en Bolivia, Carnaval de Recife en Brasil, Carnaval de Podence en Portugal entre otros que gozan del reconocimiento de patrimonio cultural e inmaterial de la humanidad

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

Background: The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes. Methods: LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January–December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien–Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141). Results: A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively. Conclusions: This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
