Analyzing Inundation Impacts on Transportation Network - The Case Study of Vadodara City
Authors: Patel Kruti
Published: June 2021

Inundation and related problems have become more uncontrollable all over the world leading to unexpected deaths, severe damage to infrastructure, and epidemics like conditions every year. A great number of cities in India have reported a series of heavy hazardous precipitation events during past few years. The immediate effects observed of floods specifically in urban areas are on the transportation network leading to its disruption. Most of the studies on transportation susceptibility including immediate and shortly after inundation events consider topographic properties along with supply and demand side of transportation system to access the disruption caused. In response to such events, this study aims to provide framework to access the susceptibility to urban road network due to inundation events. An integrated framework between meteorological information, land use functions, and hydrodynamic model simulated in HEC-RAS with rainfall event with 1-in-100 year is used for the analysis of the impacts being generated on the transportation infrastructure by such event. A critical map and index is developed to identify affected road length susceptible to flood. It has been observed that more than 40 percent of road length across the network has been affected by such unpredictable events. Also, there is a significant decrease in average speed of movement as compared to average normal speed observed on the normal days.
Challenges in Behaviour Modelling of Mode Choice Model - A Peek into Indian Scenario
Authors: C M Sreeparvathy
Published: June 2021

Mode choice model is one of the crucial steps in the process for Transportation demand modelling. It fore-tell the share of trips attracted to public transportation. Mode choice models compacts very closely with the human choice making behaviour and this continues to attract researchers for further exploration of individual choice making process. The objective of this paper is to observe keenly on the challenges that a modeller will face in Indian scenario. A variety of models are available for prediction. But with the close review it is observed that all these models work either at aggregate level or disaggregate level which works on certain assumptions. This is definitely not going to reflect the actual mode choice behaviour. The particular characters that makes a difference from the world scenario discussed in this paper are diversity in decision making of individual, diversity in socio-economic characteristics, pride and prejudices in mindset that affect the false representation of data, concept of ridesharing and the inhibition in acceptance of the same, travel distance and mode availability in urban and rural scenario. It can be concluded that selecting a model that depict the true nature of commuter is a challenging process. The well-known models available can be trained and calibrated to suit to the need of Indian scenario. Use of machine learning and data mining could be a very useful tool in this model building as all the required changes can be incorporated efficiently
Prophecy on Programming Language using Machine Learning Algorithms
Authors: Thube Komal Bhaskar
Published: June 2021

A programming language is a computer language developers use to develop software programs, scripts, or other sets of instruction for computers to execute. It is difficult to determine which programming language is widely used. In our work, I have analyzed and compared the classification results of various machine learning models and find out which programming language is widely used by developers. I have used Support Vector Machine (SVM), K neighbor classifier (KNN),Decision Tree Classifier(CART) for our comparative study. My task is to analyze different data and to classify them for the efficiency of each algorithm in terms of accuracy, precision, recall, and F1 Score. My best accuracy was 94.29% percent which was found using SVM. These techniques are coded in python and executed in Jupyter NoteBook, the Scientific Python Development Environment. Our experiments have shown that SVM is the best for predictive analysis and from our study that SVM is the well-suited algorithm for the prediction of the most widely used programming language.

Published: June 2021

To minimize the adverse effects of highway construction hazards, it becomes imperative to evaluate the risk before planning and manage the risks. From design and planning until the project is completed, risks factors are present everywhere. To improve the effectiveness of a highway construction project, it becomes necessary to reduce the risk factor to a defined assessment for timely, safe, and economical completion. Identifying, classifying, and assessing different hazards in the design of highway a project is the focus of this research. Risks from legal proceedings, such as contract disputes, disputes between the government and other parties, land acquisition, and so on, are assessed, and cases are reported. After that, a site survey will be conducted among professionals to evaluate the likelihood of an event and the risk of impact. Extreme, High, Medium, Low, and Minimum are the five risk classes that must be assigned to risk. Risk factors are also rated according to their severity. In order to reduce the cost of the project, the maximum probability of the event and the maximum impact risk must be minimized. The most significant risk is as follows: Money/Funds, Heritage issues, Concerns around mineral mining, Utilities were not moved in a timely manner, Skilled Labour, Cost of land acquisition is uncertain, Schedule for land acquisition.

Finite State Machine based Programmable Memory Built-in Self-Test
Authors: Praneeth B V S Sai
Published: June 2021

We propose a methodology to design a Finite State Machine(FSM)-based Programmable Memory Built-In Self Test (PMBIST) which includes a planned procedure for Memory BIST which has a controller to select a test algorithm from a fixed set of algorithms that are built in the memory BIST. In general, it is not possible to test all the different memory modules present in System-on-Chip (SoC) with a single Test algorithm. Subsequently it is desirable to have a programmable Memory BIST controller which can execute multiple test algorithms. The proposed Memory BIST controller is designed as a FSM (Finite State Machine) written in Verilog HDL and this scheme greatly simplifies the testing process and it achieves a good flexibility with smaller circuit size compared with Individual Testing designs. We have used March test algorithms like MATS+, March X, March C- to build the project.

Deep Learning for Leaf Disease Detection using CNN
Authors: Reddy Abhinay Kumar
Published: June 2021

Agriculture is the backbone of the Indian economy. About 70% of people rely on it and share a large portion of GDP. Diseases in plants especially in the leaves affect the reduction of both quality and quantity of agricultural products. The human eye is not so powerful to detect minute differences in the infected part of the leaf. In this paper, we offer a software solution to automatically detect and diagnose plant leaf diseases. In this we use image processing techniques for the diagnosis and early diagnosis can be done as elsewhere. This approach will improve crop production. It involves several steps. Picture detection, pre-image processing, percentage separation, extraction and neural features. Recently, many researchers have advocated since the success of in-depth computer literacy the idea of improving the effectiveness of diagnostic programs. Unfortunately, most of these studies did not use the latest in-depth formats and were based on AlexNet, GoogleNet or similar properties. Moreover, deep-seated mechanisms do not exist to take advantage of it, making these deep divisions invisible and suitable as black people boxes. In this project, we tested the many technological approaches of the Convolutional Neural Network (CNN) buildings using various learning strategies in the public database of plant diseases separation. These new structures exceed the high-quality effects of plant diseases in stages with very high accuracy. In addition, we have suggested the use of saliency maps as a way to visualize and interpret CNN classification.

Climate-Change affecting unfavorably because of upward push in worldwide temperature alteration and that too alarmingly. Ancient Air bubbles buried in Antarctic Ice to shed more light on Global Warming. It has happened in the North-Atlantic and may happen again. According to scientists, a dangerous atmospheric deviation could prompt prolonged chill and move the Earth towards a brand new age and a new defined climate that would be an effect of the worldwide environmental change. On such conditions James White, a geography educator at Colorado University, Boulder, not engaged with the investigation, said that albeit the ice-age proof showed that degrees of CO2 and further ozone harming substances rose and fell in reaction to heating and cooling , the gases could clearly take the lead as well. Global Climate withinside the fresh past: In the 90’s decades there has stood an experience and witnessing of the extremes of various weather events. In the warmer temperature of century was recorded and a share of the majority noticeably terrible floods all in the course of the planet. The one such inconstancy is the staggering dry period in the Sahel-area which lies in South-of-Sahara desert, from 1967-1977. During the 1930’s there were severe drought that occurred in the south-western Great Plains of the U.S which was described as DUST BOWL. The after-effects of the Global-Climate-Change are severe and tell us about the various impacts. They are:- A. Crop yield or Crop failures, B. Floods, C. Migration of people. These are various influences of the Global-Climate-Change that effect the biosphere from many ways as Climate-Change directly affects the biosphere which is the only sphere wherein lifestyle exists and where life can exist.

Authors: Gaspar Catarina
Published: July 2021

This paper examines writing and orthography in the work of Latin grammarians and spelling variants in epigraphic texts. It focuses on the uses of the letter H and the spelling of the word sepulchrum. The word’s spelling seems to be connected to the spelling of other words through the adjective pulcher, pulchra, pulchrum. The analysis indicates that the teaching and learning of orthography had a limited influence on epigraphic texts, but there is evidence of the consistently high frequency of the spelling sepulcrum. The paper also shows how data on Latin orthography can help in understanding the chronology of the evolution of spelling in epigraphic texts.

Published: June 2021

INTRODUCCIÓN:
La prevalencia de deterioro cognitivo leve (DCL) y demencia se ha descrito recientemente como alta en Colombia, debido al aumento de la población adulta mayor y a su baja escolaridad. Aun no es claro el mecanismo por el cual la diabetes mellitus (DM) o la hipertensión arterial (HTA), en ausencia de accidente cerebrovascular (ACV), aumentarían el riesgo de DCL o demencia.

OBJETIVO:
Revisar en la literatura la posible asociación de HTA y DM con el riesgo de progresión a DCL.

MÉTODOS:
Se realizó una búsqueda en las bases de datos de las publicaciones entre los años 2007 y 2017, de cohortes y casos y controles de adultos de 65 años o más con HTA o DM y que evaluaran como desenlace DCL o demencia.

RESULTADOS:
La revisión arrojó doce artículos que cumplieron con los criterios de selección. Seis artículos reportaban relación entre HTA y riesgo de presentar deterioro cognitivo; de estos, cinco artículos presentaban como desenlace demencia vascular (DVa) y el otro tanto demencia tipo Alzheimer (DTA) como DVa. Además, informan sobre el riesgo de presentar demencia según las cifras de presión arterial sistólica y diastólica. De los seis estudios de cohortes incluidos, cinco encontraron una relación significativa entre DM y progresión a DCL o DTA.

CONCLUSIÓN:
Los pacientes con HTA tienen mayor riesgo de DVa, seguido por demencia mixta. La DM se asocia con una mayor frecuencia de DTA, en especial si la DM aparece en edades tempranas.

Este trabalho é resultado parcial do Grupo de Estudos Prolim - Processos e Linguagens das Imagens Mídias - CNPq, teve como objeto principal de estudo a trilha sonora do comercial natalino de 2018 da Apple, intitulado Share your gifts (“Compartilhe seus presentes”), a partir da qual se realiza uma análise de sua interação midiática com o consumidor a partir da produção e da distribuição no storytelling. A utilização do formato de storytelling em seu comercial natalino de 2018 empregou uma trilha sonora que é destacada como conexão emocional entre a marca e o sujeito, o que contribui para suas relações de mercado, algo que nos leva a verificar a interferência e atenção gerada nos interlocutores a partir da trilha sonora usada. Com base no método de análise do discurso, analisamos o referido comercial e verificamos a forma como os interlocutores transmitem a mensagem intervém diretamente na história contada pela empresa; desse modo, é necessária a compreensão das técnicas usadas do storytelling na campanha, como também as práticas midiáticas e mercadológicas para fortalecer a marca e influenciar diretamente na relação entre sujeito e meios de comunicação. Nesse intercâmbio dos meios de comunicação, também levamos em consideração as questões emocionais — presentes nessa trilha sonora do storytelling —, que fazem parte da tendência comunicacional globalizada; ao mesmo tempo, verificamos a mensagem em seu formato de divulgação que se destacada entre as grandes marcas e suas influências midiáticas. Apreendemos que o uso do storytelling se tornou um dos meios de convergências comunicacionais das grandes marcas, as quais tendem a focar a interação midiática com o sujeito e alavancar o seu posicionamento no mercado, a partir deste novo formado de consumidor, que se torna o porta voz da divulgação online - um consumidor ativo, influenciando diretamente nestas mediações das mensagens.

Published: June 2021

La instalación interactiva constituye actualmente una alternativa importante para difundir obras en museos y convocar nuevos públicos, pero una de sus limitaciones es diagnosticar a tiempo problemas potenciales que puedan darse en el proceso de comunicación interactivo. Frente a esta hipótesis de partida, se planteó como objetivo la creación de un laboratorio audiovisual pedagógico capaz de evaluar y diagnosticar posibles dificultades en dicho proceso comunicativo y ayudar a establecer las estrategias para adelantar propuestas alternativas y mejorar la interacción entra la obra y el público. En consecuencia, se adecuó un laboratorio de ensayo en un estudio de televisión donde se aplicó la prueba emot-brain: Método de evaluación de experiencia de usuario a la instalación Uno se muere y sigue aprendiendo a pintar con un grupo focal de estudiantes y profesores de la universidad del Valle. El ensayo arrojó indicadores tímicos que se registraron a través del dispositivo Emotiv-epoc y relaciones cronémicas y proxémicas que se sistematizaron a través de la observación participante, cámaras infrarrojas y de alta sensibilidad y entrevistas. Las evaluaciones arrojaron evidencias de las fortalezas y limitaciones en la praxis de las obras expuestas y permitieron advertir, comprender y enriquecer las relaciones interactivas. Con estos insumos se ajustaron los correctivos y se difundió la obra. La experiencia constituye un recurso de apoyo para orientar a estudiantes y creadores frente a la incertidumbre sobre la funcionalidad de sus obras con pruebas para apoyar procesos creativos. De esta manera, se revelan aspectos que los creadores no advierten en la concepción de las obras.
Desinformación en contextos de polarización social: el paro nacional en Colombia del 21N
Authors: Rodríguez Pérez Carlos , Ortiz Calderón Laura Sofía , Esquivel Coronado Juan Pablo
Published: June 2021

La desinformación se ha convertido en un fenómeno mundial que incide en la opinión pública. El objetivo de este artículo es analizar los contenidos evaluados como desinformación por tres medios de verificación durante el paro nacional del 21 de noviembre del 2019. Específicamente, se pretende conocer cómo la desinformación afecta negativamente los bienes intangibles (legitimidad, reputación y confianza) de actores sociales, políticos e instituciones. Metodológicamente, se realizó un análisis de contenido cuantitativo y etnográfico para analizar los datos e identificar argumentos y patrones de relación de la desinformación con su afectación en la intangibilidad de estos clústeres de actores. Los resultados obtenidos destacan que la desinformación propagada vinculó la violencia y los actos punibles tanto a los actores sociales como a la fuerza pública, especialmente al Esmad y a la policía, con el fin de deslegitimar y desacreditar las razones de la protesta o bien su labor de garantizar el orden público y la seguridad. Respecto a la desinformación vinculada con los actores políticos se observa que el líder de la izquierda fue el más afectado por contenidos que polarizaban y proclamaban posiciones extremas cercanas a la subversión. Por último, se discuten las implicaciones de la desinformación en la ciudadanía y cómo incide sobre la legitimidad, reputación y confianza. Además, se evidencia que la desinformación imita la estética de medios de comunicación para dotarse de una falsa legitimidad y credibilidad ante los ojos de la audiencia.

Published: June 2021

The purpose of this study is to design a Building Information Modelling (BIM) integration model for architectural education in adopting BIM culture. Most of the current models on BIM adoption are directed toward the realm of construction industries (consultant firms and contractors) and less on higher education institutions. The discourse on education is mostly concerning experimentation on curricular integration and the lack of general concepts of integration. The main research inquiry of this study is concentrated on which criteria are best suited to the education culture. Utilizing reflective discussion of past experiences and a semisystematic literature review, detailed criteria to capture the multidimensional facets of BIM adoption are proposed. The study proposes the model that offers six main integration criteria: (a) institution vision and priorities, (b) infrastructure, (c) curriculum integration, (d) human resources, (e) knowledge organization, and (f) change management. The application of the model may be limited to architectural schools which are still in the initial process of BIM adoption but the comprehensiveness of the model may possibly be developed as the basis for readiness assessment, roadmap development, and exchange terminologies between education and the wider context of architecture, engineering, construction, operation and management industries.

Published: June 2021

The emergence of widespread advanced digital technologies being utilised into the construction industry practices adds a new dimension to the better integration and collaboration of construction projects. Nowadays, Building Information Modelling (BIM) is recognized as a modern tool to enhance greater visualisation of project information and provides opportunities for an effective communication platform within a multi-organisations context. Despite the wave of enthusiasm for BIM studies having shown exceptional benefits, the context of social collaboration across multi-organisations is still limited. Thus, this paper aims to present the review of key indicators towards social collaboration achievement within multi-organisations in the BIM construction context. Based on a comprehensive review, five key indicators are identified that contribute to the social collaboration achievement in BIM construction context. Including organisational perspectives, foundational setting, behavioural perspective, educational perspective and enforcement platform. The findings also revealed the extend of the spectrum of collaboration literature in the context of construction domain particularly on characterisation and its importance towards social collaboration within a multi-organisation in digital environment.

Published: June 2021

Quantity surveying firms (QSFs) in Nigeria are faced with numerous challenges and stiff competitions in the construction industry that have really threatened the growth and survival of the firms. Therefore, this study examined the current growth status of QSFs in Lagos and Ondo States, Nigeria. This was achieved by assessing some germane growth indicators of firms which include asset, profit, staffing, clients and so on. Descriptive research design was adopted through a census survey of all quantity surveying firms in the study area. Questionnaires were distributed to top management executives of the firms and the data adequately analysed using analysis of variance (ANOVA) to compare the growth indicators (at startup level and current level) and test statistic F was computed to test hypotheses. It was revealed that QSFs have not been experiencing growth in the number of employees, number of clients and asset owned by the firms. Furthermore, there is decrease in profit which is the indicator that most determines firm’s growth. Therefore, the study recommends that QSFs in Nigeria should maximize their profit level so that employees’ strength and salary are not affected since QSFs depends on the skill of quantity surveyors in order to succeed and survive.

Se presentan los resultados de una investigación basada en vigilancia tecnológica, de carácter documental comparativa y con perspectiva de prospectiva, sobre los avances y brechas para la implementación de la cadena de suministro para el desarrollo y futuro aprovechamiento de la energía eólica marina en Costa Rica. Esta economía emergente se ha destacado, internacionalmente, por asumir y liderar compromisos significativos con los ODS, con la acción climática y con la descarbonización de la economía. Por lo tanto, resulta fundamental mantener la visión energética 100% renovable, pero también incentivar la inclusión, diversificada y progresiva, de energía no convencional, como el viento marino. Los hallazgos confirman los múltiples y significativos desafíos que Costa Rica debe enfrentar y superar para la planificación, construcción y operación de plantas eólicas marinas. De la misma forma en que el país planificó el uso de recursos energéticos continentales, deberá hacerlo con el desarrollo patrimonio de energía marina.
Los nuevos retos del comercio internacional colombiano y su transformación a nivel mundial
Authors: Pinillos Villamiza Jesús Alexander , Diaz Rodriguez Johan Rica , Osorio Camacho Juan Sebastian
Published: June 2021

Colombia decidió internacionalizar su economía, llevando a cabo un proceso continuo de globalización teniendo como base el comercio exterior y el aumento tanto de importaciones como de exportaciones. Esto se definió desde un principio como el punto ideal dentro del desarrollo del país, y de esta manera a través del tiempo se negociaron aproximadamente 9 tratados de libre comercio que de alguna manera hacen más fácil el acceso de los demás países a las mercancías nacionales. Sin embargo, cabe resaltar que siempre se han tenido problemas en cuanto a la cadena de suministros y como se implementa desde las pequeñas empresas hasta las macroempresas, ya que no se ha planteado que la base de este problema es la creciente falta de productividad y competitividad de la economía colombiana, esto debido a que existe una falta de reformas y leyes que permitan reducir de gran manera los costos dentro del país, lo que se agrava en el momento de la inexistencia de una política que proteja de manera coherente el comercio exterior.

Es un paciente masculino de edad media que habita en zona subtropical con diagnóstico de enfermedad de Crohn tratado con corticoide e inmunomoduladores, presentaba dolor abdominal y anemia crónica de 1 año de evolución, analítica negativa para parásitos, reactantes de fase aguda normales, gastroscopia y colonoscopia previas (6 meses) sin hallazgos relevantes. Por la persistencia del cuadro clínico se repitieron los estudios endoscópicos en los que se visualizaron hemorragias subepiteliales con resultados histopatológicos de Strongyloides stercoralis.

Conclusión: en el contexto de un paciente inmunocomprometido, en zona endémica y con evolución tórpida, debe obligar a realizar un diagnóstico diferencial en el que se debe sospechar siempre de infestación parasitaria. Aunque la endoscopia no se necesita para el diagnóstico de estrongiloidiasis, su intervención puede ser oportuna.

Introducción: los tumores estromales gastrointestinales (GIST) representan hasta el 2 % de las neoplasias gastrointestinales, estos aparecen en cualquier parte del tracto gastrointestinal y son encontrados más frecuentemente en el estómago (60 %). El diagnóstico se realiza por la expresión de un receptor de factor de crecimiento de tirosina-cinasa, antígeno de diferenciación (CD) 117, lo que lo diferencia de los otros tumores mesenquimales como leiomiomas, leiomiosarcomas, leiomioblastomas y tumores neurogénicos, que no expresan esta proteína.

Objetivo: el objetivo de nuestro trabajo es caracterizar los GIST de localización gástrica con respecto a su presentación clínica, diagnóstico, manejo, recurrencia y supervivencia.

Métodos: se trata de un estudio observacional, retrospectivo basado en una serie de casos. Se realizó una extracción de la información por medio de la revisión de las historias clínicas de los pacientes con GIST gástricos en un centro oncológico de Bogotá entre enero de 2005 y diciembre de 2015. La información recolectada incluyó tipo de manejo y abordaje quirúrgico, localización, tamaño, índice mitótico y clasificación de riesgo.

Resultados: se encontraron 31 pacientes con diagnóstico de GIST gástrico. La edad media fue de 62,3 años, con una mediana de 61 años. De los 31 pacientes, 18 fueron mujeres y 13 hombres. El tiempo de seguimiento estuvo entre un mínimo de 2,4 meses y un máximo de 214 meses, La mediana de seguimiento fue de 36 meses.

Conclusiones: los GIST son tumores potencialmente malignos, y el de localización gástrica es el más frecuente. El diagnóstico y tratamiento dependen de su tamaño y localización dentro del estómago. El manejo es variado y consiste en la resección quirúrgica, en la que los procedimientos son mínimamente invasivos, en combinación con la endoscopia, que son una buena alternativa al tratamiento abierto hasta que haya necesidad de terapia sistémica.

Introducción: La biopsia hepática es la prueba de oro para el diagnóstico de las enfermedades que comprometen el hígado, una muestra adecuada y una muy buena lectura son elementos que determinan la utilidad de la prueba y el impacto en la toma de decisiones.

Objetivo: Evaluar la calidad de las biopsias hepáticas a partir de la frecuencia de un “diagnóstico definitivo” en la lectura de las mismas y su relación con el número de espacios porta y su longitud informada.

Materiales y métodos: Estudio observacional retrospectivo basado en registros, entre el 1 de enero del 2010 y el 30 de julio del 2017. Se realizó biopsia hepática, revisión de historias clínicas y evaluación del resultado de patología.

Resultados: Se incluyeron 659 informes de patología de 10 instituciones. El porcentaje de reporte de espacios porta varió entre un 15% y un 87.4 %. La mediana de longitud de la biopsia fue de 15 mm (RIQ 10-20) y la del número de espacios porta fue de 10 (RIQ 7-15). Los diagnósticos definitivos se presentaron entre 35% y 69 %, diagnósticos probables entre 25% y 63 % y sin diagnostico entre un 5% y 31.8%. En el resultado de la regresión logística del diagnóstico se encontró que el número de espacios porta presentó un OR de 1.10 (IC 95%1.04-1.17) y la longitud OR 1.76 (1.10-2.82),

Conclusiones: En Bogotá existen 3 instituciones hospitalarias con un rendimiento en el diagnóstico en cuanto a lectura de biopsias hepáticas por encima del 60 %.  El diagnóstico definitivo en la biopsia hepática se asoció en este estudio a la presencia de un cilindro de tejido hepático de longitud y número de espacios porta adecuados.
Gastrostomía descompresiva en obstrucción gastrointestinal maligna: reporte de caso y revisión de la literatura
Authors: Morros González Elly Alejandra , Vargas Rubio Rómulo Darío , Ovalle Hernández Alan Felipe
Published: June 2021

La gastrostomía descompresiva durante los últimos años ha surgido como una alternativa de manejo para la paliación de síntomas en personas con enfermedad oncológica terminal que desarrollan obstrucción intestinal sin indicación quirúrgica inicial y es refractaria al manejo médico. El objetivo es brindar calidad de vida a través de la restauración de la vía oral. Sus contraindicaciones han variado con el tiempo; sin embargo, han surgido nuevas técnicas que permiten ampliar el espectro de indicaciones de este procedimiento. Se ha descrito que permite apoyar el control de síntomas, el retorno de la persona a su lugar de cuidado y, posiblemente, el reinicio de la vía oral con la intención de mantener la calidad de vida de la persona.

Background: Some of atrial fibrillation (AF) drivers are found in lesser
late-gadolinium enhancement (LGE) areas, as well as heterogenous ones.
The atrial wall thickness (AWT) has been reported to be important as a
possible AF substrate. However, the AWT and degree of LGEs as an AF
substrate has not been fully validated in humans. Objective: The purpose
of this study was to evaluate the impact of the AWT in lesser LGE areas
on AF drivers. Methods: A total of 287 segments in 15 persistent AF
patients were assessed. AF drivers were defined as non-passively
activated areas (NPAs), where rotational activation was frequently
observed, and were detected by the novel real-time phase mapping (ExTRa
Mapping). Lesser LGE areas were defined as areas with a volume ratio of
the enhancement voxel of <10%. The AWT was defined as the
minimum distance from the manually determined endocardium to the
epicardial border on the LGE-MRI. Results: NPAs were found in 20
(18.0%) of 131 lesser LGE areas where the AWT was significantly thicker
than that in the passively activated areas (PAs) (2.46±0.26 vs.
2.20±0.25 mm, p<0.001). However, NPAs were found in 61
(21.3%) of 287 LGE areas where the AWT was similar to that of the PAs
(2.24±0.24 vs. 2.22±0.25 mm, p=0.58). An ROC curve analysis yielded an
optimal cutoff value of 2.24 mm for predicting the presence of an NPA in
lesser LGE areas. Conclusion: The location of AF drivers in lesser LGE
areas might be more accurately identified by evaluating the AWT.
