BIM-based LCSA application in early design stages using IFC

Life Cycle Sustainability Assessment (LCSA) is an integrated method that combines environmental, economic, and social assessments. Its methodological development remains under discussion, mainly regarding the building design. This paper aims to provide a systematic, interoperable, and open-source approach towards implementing LCSA in Building Information Modelling (BIM) in five steps. A harmonized data structure that enriches BIM objects is proposed. Automation in the principal evaluation step is provided by integrating new parameters into the current Industry Foundation Classes (IFC4). A Dynamo script verifies its utility in a case study in Spain using real-time calculations and visualizations. Two alternative structural systems are assessed, and identification is made of the lowest CO2 emitter, the lowest cost, and the most beneficial system for local employment. The approach can be employed to evaluate other indicators and building systems in other countries. Challenges and limitations in the standardization and harmonization of the three dimensions are identified

Page charge of D-branes and its behavior in topologically nontrivial B-fields

The RR Page charges for the D(2p+1)-branes with B-field in type IIB supergravity are constructed consistently from brane source currents. The resulting Page charges are B-independent in the nontrivial and intricate way. It is found that in topologically trivial B-field the Page charge is conserved, but in the topologically nontrivial B-field it is no longer to be conserved, instead there is a jump between two Page charges defined in each patch, and we interpret this jump as Hanany-Witten effect.Comment: 25 pages, 4 figures, typos corrected and reference adde

The Role of Myofunctional Therapy in Treating Sleep-Disordered Breathing: A State-of-the-Art Review

Myofunctional therapy (MFT) may have a role in improving muscle tone and alleviating upper airway collapse in sleep-disordered breathing. The purposes of this state-of-the-art review are to first review systematically the current literature on the effectiveness of MFT in treating sleep-disordered breathing and then to provide an overview of the current understanding of patient selection, side effects, type and duration of exercises, guidance of exercise performance, evaluation of results, and how best to promote adherence. PubMed (Medline), the Cochrane Library, and the EMBASE, Scopus and SciELO databases were checked for relevant studies by three authors, and a total of 23 studies were included. This review focuses only on adults with sleep-disordered breathing. The available evidence shows a positive effect of MFT in reducing sleep apnoea, as measured using polysomnography and clinical variables (including snoring). There is no evidence of the utility of MFT for treating upper airway resistance syndrome, the duration of the effects of MFT, or regarding which MFT protocol is best. Despite these knowledge gaps, the available evidence suggests that MFT is a safe treatment modality

Úlcera por presión del descuido al cuidado

Este caso que presentamos no es sólo curioso como caso clínico, sino que también destaca por la atención clínica que se le ha prestado. Es un caso clínico centrado en la ausencia de cuidados necesarios para un paciente, un paciente especial con alzheimer en estado avanzado.Queremos llamar la atención sobre los cuidados que prestamos en todos los niveles asistenciales:primaria, especializada, centros asistenciales de agudos y crónicos o residencias. Muchas veces llegamos a encontrarnos pacientes con tal deficiencia de cuidados, que genera en los profesionales de la sanidad un debate sobre si valoramos correctamente a los pacientes o estamos frente a una cadena de producción de coches.El hombre nace y muere pero debe morir dignamente, pero también debe ser atendido dignamente y tener una calidad de vida y cuidados adecuados.Los pacientes son personas y, como tal, tienen desde su nacimiento esa dignidad, en consecuencia todo enfermo debe ser tratado lo mejor posible y con todos los cuidados que necesite. Entonces, ¿por qué ese descuido y dejadez? ¿Puede ser por motivación económica, falta de formación, inexistencia de ética profesional, no hay material, rutina en procedimientos,falta de instrumentos de valoración y diagnóstico para atender con calidad, eficacia y eficiencia...? Hablamos de úlceras por presión, y todos sabemos y hablamos de las causas, que en un 95% son evitables. Pero la realidad es que el concepto o filosofía de Enfermería, la cual es la de CUIDAR, no es asumido en muchas ocasiones.Enfermerí

Building Process-Oriented Data Science Solutions for Real-World Healthcare

The COVID-19 pandemic has highlighted some of the opportunities, problems and barriers facing the application of Artificial Intelligence to the medical domain. It is becoming increasingly important to determine how Artificial Intelligence will help healthcare providers understand and improve the daily practice of medicine. As a part of the Artificial Intelligence research field, the Process-Oriented Data Science community has been active in the analysis of this situation and in identifying current challenges and available solutions. We have identified a need to integrate the best efforts made by the community to ensure that promised improvements to care processes can be achieved in real healthcare. In this paper, we argue that it is necessary to provide appropriate tools to support medical experts and that frequent, interactive communication between medical experts and data miners is needed to co-create solutions. Process-Oriented Data Science, and specifically concrete techniques such as Process Mining, can offer an easy to manage set of tools for developing understandable and explainable Artificial Intelligence solutions. Process Mining offers tools, methods and a data driven approach that can involve medical experts in the process of co-discovering real-world evidence in an interactive way. It is time for Process-Oriented Data scientists to collaborate more closely with healthcare professionals to provide and build useful, understandable solutions that answer practical questions in daily practice. With a shared vision, we should be better prepared to meet the complex challenges that will shape the future of healthcare

Study of Spin and Decay-Plane Correlations of W Bosons in the e+e- -> W+W- Process at LEP

Data collected at LEP at centre-of-mass energies \sqrt(s) = 189 - 209 GeV are used to study correlations of the spin of W bosons using e+e- -> W+W- -> lnqq~ events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e+e- -> W+W- -> lnqq~ and e+e- -> W+W- -> qq~qq~ events. Decay-plane correlations, consistent with zero and with the Standard Model predictions, are measured

Ultrarelativistic sources in nonlinear electrodynamics

The fields of rapidly moving sources are studied within nonlinear electrodynamics by boosting the fields of sources at rest. As a consequence of the ultrarelativistic limit the delta-like electromagnetic shock waves are found. The character of the field within the shock depends on the theory of nonlinear electrodynamics considered. In particular, we obtain the field of an ultrarelativistic charge in the Born-Infeld theory.Comment: 10 pages, 3 figure

Measurement of the Cross Section for Open-Beauty Production in Photon-Photon Collisions at LEP

The cross section for open-beauty production in photon-photon collisions is measured using the whole high-energy and high-luminosity data sample collected by the L3 detector at LEP. This corresponds to 627/pb of integrated luminosity for electron-positron centre-of-mass energies from 189GeV to 209GeV. Events containing b quarks are identified through their semi-leptonic decay into electrons or muons. The e+e- -> e+e-b b~X cross section is measured within our fiducial volume and then extrapolated to the full phase space. These results are found to be in significant excess with respect to Monte Carlo predictions and next-to-leading order QCD calculations
