Composite Digital Elevation Model of the Vestfold Hills (REMA / Smith 2015)
No full textProgress Code: completedStatement: REMA DEM values have typical elevation errors of less than 1m. However, errors are higher in rougher terrains. D.T. Smith (2015) values have horizontal accuracy between 2-12 m and vertical accuracy between 1-5 m.The Davis Aerodrome Project (DAP) collected a range of environmental survey data over several field seasons to support a comprehensive environmental assessment of the proposed aerodrome. This data includes flora, fauna, soils, lake ecosystem, nearshore, marine, air quality and meteorological information which has been collected by a number of different methods, and extends across the current Davis Station, proposed aerodrome and supporting infrastructure footprint (Ridge Site), previous sites considered for the aerodrome (Heidemann Valley, Adams Flat), as well as locations across the Vestfold Hills away from any of the proposed developments. <br/><br/>The Reference Elevation Model of Antarctica (REMA) (Howat et al., 2019) is an 8 m resolution elevation model of the entire Antarctic continent. For many parts of Antarctica, it is the finest scale digital elevation model (DEM) available in both ice covered and ice-free areas. REMA is derived from stereophotogrammetry of submeter resolution optical, commercial satellite imagery and is described as have typical elevation errors of less than 1m. However, errors are higher in rougher terrains, and on top of this REMA values are masked from terrain below sea level that lies within 800 m of the coastline. For the Vestfold Hills this presents an issue as some valleys within 800 m of the coast lie below sea-level. Here we use, a second DEM of the Vestfold Hills developed by D.T. Smith (2015) at 10m resolution and with horizontal accuracy between 2-12 m and vertical accuracy between 1-5 m to infill areas below sea level (0 m) in the REMA DEM to create a composite DEM of the Vestfold Hills. <br/><br/>Once both DEMs were adjusted to height above sea level, they were combined using the following steps:<br/>First, to account for any slight offset between the two layers, D.T. Smith (2015) DEM values were corrected to REMA values using a linear regression (Yrema = β0 + β1(Xsmith) + ε). The linear regression used all D.T. Smith (2015) values below 30 m to train the model. The model input was cropped at 30m to avoid any lever effects from higher DEM values. Second, a transition zone was defined between 0m and 20m to blend the two layers together. Values within the transition zone (tz) were calculated using a moving weighted average of D.T. Smith (2015) and REMA values such that where D.T. Smith (2015) = 0 m, wt_SMITH = 1 and wt_REMA = 0; and where D.T. Smith (2015) = 20 m, wt_SMITH = 0 and wt_REMA = 1 using the following formulas:<br/><br/>tz=wt_SMITH×SMITH + wt_REMA×REMA <br/><br/>where<br/><br/>wt_SMITH = 1 - ((SMITH-t_min)/∆t)<br/><br/>and,<br/><br/>wt_REMA = 1- wt_SMITH<br/><br/>and, SMITH is the D.T. Smith (2015) value of a cell, REMA is the REMA value of the cell, t_min and t_max are the minimum and maximum Smith values of tz, respectively (in this case 0 m and 20 m) and Δt is the difference between the tmin and tmax ∴ Δt = 20. <br/><br/>The three layers REMA, tz and D.T. Smith (2015) combined to create an improved composite DEM that corrected for missing and erroneous values of REMA in areas below sea level. D.T. Smith (2015) values were highly congruous with REMA values after correction to sea level (r2 = 0.85, β0 = 0.10, β1 = 0.99) and combined with tz values to create a fairly seamless combined DEM

High-resolution topography of the Antarctic Peninsula combining the TanDEM-X DEM and Reference Elevation Model of Antarctica (REMA) mosaic
No full textThe Antarctic Peninsula (AP) is one of the widely studied
polar regions because of its sensitivity to climate change and potential
contribution of its glaciers to global sea level rise. Precise digital elevation models (DEMs) at a high
spatial resolution are much demanded for investigating the complex glacier
system of the AP at fine scales. However, the two most recent
circum-Antarctic DEMs, the 12 m TanDEM-X DEM (TDM DEM) from bistatic interferometric synthetic aperture radar (InSAR)
data acquired between 2013 and 2014 and the Reference Elevation Model of
Antarctica mosaic (REMA mosaic) at an 8 m spatial resolution derived from
optical data acquired between 2011 and 2017 have specific individual
limitations in this area. The TDM DEM has the advantage of good data
consistency and few data voids (approx. 0.85 %), but there exist residual
systematic elevation errors such as phase-unwrapping errors in the
non-edited DEM version. The REMA mosaic has high absolute vertical accuracy,
but on the AP it suffers from extended areas with data voids (approx. 8 %). To
generate a consistent, gapless and high-resolution topography product of the
AP, we fill the data voids in the TDM DEM with newly processed TDM raw DEM data
acquired in austral winters of 2013 and 2014 and detect and correct the
residual systematic elevation errors (i.e., elevation biases) in the TDM DEM
with the support of the accurately calibrated REMA mosaic. Instead of a
pixelwise replacement with REMA mosaic elevations, these provide
reference values to correct the TDM elevation biases over entire regions
detected through a path propagation algorithm. The procedure is applied
iteratively to gradually correct the errors in the TDM DEM from a large to
small scale. The proposed method maintains the characteristics of an InSAR-generated DEM and is minimally influenced by temporal or penetration
differences between the TDM DEM and REMA mosaic. The performance of the
correction is evaluated with laser altimetry data from Operation IceBridge
and ICESat-2 missions. The overall root mean square error (RMSE) of the
corrected TDM DEM has been reduced from more than 30 m to about 10 m which
together with the improved absolute elevation accuracy indicates comparable
values to the REMA mosaic. The generated high-resolution DEM depicts the
up-to-date topography of the AP in detail and can be widely used for
interferometric applications as well as for glaciological studies on
individual glaciers or at regional scales.</p
Resazurin MicrotiterAssay (REMA) modificado para detecção de resistência à ciprofloxacino e linezolida em micobactérias de crescimento rápido
No full textThe rapidly growing mycobacteria (RGM) comprise a group of non-tuberculous mycobacteria (NTM) and contains species of pathogenic microorganisms which cause various types of localized and disseminated infections, especially in skin, bones and joints. These infections are in most cases associated with immunocompromised patients and require long term treatment. The susceptibility test recommended by the Clinical and Laboratory Standards Institute (CLSI) for RGM pathogenic requires visual reading which makes it very subjective. The method resazurin microtiter assay method (REMA) has been used in research to determine the minimum inhibitory concentration (MIC) for antituberculous drugs because it is simple, low cost and provide faster results compared to traditional methods. The aim of this study was to evaluate the in vitro effect of REMA modification for MIC determination to MCR to ciprofloxacin and linezolid in the cultivation of bacillus in culture medium containing resazurin. Were used for the study Mycobacterium chelonae, M. abscesus, M. smegmatisand M. fortuitum, and the results were compared to the susceptibility test recommended by CLSI and REMA. There was no difference in MIC for linezolid and ciprofloxacin when adding resazurin directly in the culture medium for the isolates studied. The modification of REMA by using culture medium containing resazurin previously shown to be efficient, reproducible, fast, inexpensive, easy to perform and interpret the detection of resistance to linezolid and ciprofloxacin in MCR.As micobactérias de crescimento rápido (MCR) pertencem ao grupo das micobactérias não pertencentes ao complexo Mycobacterium tuberculosis e contêm espécies patogênicas, que causam infecções disseminadas e localizadas, especialmente em pele, ossos e articulações. Essas infecções estão, na maioria dos casos, associadas a pacientes imunocomprometidos e requerem tratamento prolongado. O teste de susceptibilidade preconizado pelo Clinical and Laboratory Standards Institute (CLSI) para as espécies patogênicas desse grupo é realizado em microplacas e requer leitura visual o que o torna muito subjetivo. O resazurin microtiter assay method (REMA) vem sendo aplicado em pesquisas para a determinação da concentração inibitória mínima (CIM) para fármacos antituberculosos por ser simples, de baixo custo e proporcionar resultados mais rápidos se comparado aos métodos tradicionais. O objetivo deste estudo foi avaliar o efeito in vitro da modificação do REMA para determinação da CIM para ciprofloxacino e linezolida pelo cultivo do bacilo em meio contendo resazurina. Foram utilizados para o estudo Mycobacterium chelonae, M. abscesus, M. smegmatis e M. fortuitum. Os resultados foram comparados ao teste de susceptibilidade preconizado pelo CLSI e ao REMA tradicional. Não foi observada diferença na CIM para linezolida e ciprofloxacino quando se adiciona resazurina diretamente no meio de cultura para os isolados estudados. A modificação de REMA pela utilização de meio de cultivo contendo previamente a resazurina mostrou ser eficiente, reprodutível, rápido, de baixo custo, fácil execução e interpretação na detecção de resistência a linezolida e ciprofloxacino em MCR.29

Rapid detection of resistance to pyrazinamide in Mycobacterium tuberculosis by Resazutin Microplate Assay (REMA)
No full textTuberculosis (TB) is a chronic disease caused by an Acid Fast bacilli belonging to the Mycobacterium tuberculosis complex. Despite having almost been eradicated in developed countries, TB remains a major public health problem, especially in developing countries. Pyrazinamide (PZA) is a pro-drug used to treat TB, which requires conversion to its active form, pirazinóico acid (POA), by the pyrazinamidase enzyme (PZase), encoded by the pncA gene. Although the mechanism of action of POA remains unknown, it has been suggested that their accumulation in acidic pH, can disrupt the membrane potential of the bacillus, affecting the transport of nutrients. Early detection of drug resistance is very important for TB control and the beginning of treatment. However, the proportion method in Lowenstein-Jensen (LJ), that is routinely used in Brazil for detecting resistance in M. tuberculosis is laborious, time consuming and have low reproducibility at acid pH that is necessary to perform the test with PZA. Thus, the purpose of this study was standardize and evaluate the use of resazurin microtiter assay plate (REMA) for detection of resistant to PZA in M. tuberculosis. The research resulted the article: "Application of the resazurin microtiter assay plate (REMA) for detection of resistance in Mycobacterium tuberculosis", that shows how the REMA proposal may contribute to the rapid detection of PZA resistance, in a fast, sensitive and specific method.A tuberculose (TB) é uma doença crônica causada por bacilos pertencentes ao complexo Mycobacterium tuberculosis. Apesar de quase ter sido erradicada em países desenvolvidos, a TB continua sendo um importante problema de saúde pública, principalmente em países em desenvolvimento. A pirazinamida (PZA) é um pró-fármaco utilizado no tratamento da TB, que requer conversão à sua forma ativa, o ácido pirazinóico (POA), pela enzima pirazinamidase (PZase), que é codificada pelo gene pncA. Embora o mecanismo de ação do POA permaneça desconhecido, tem sido sugerido que o seu acúmulo em pH ácido, pode interromper o potencial de membrana do bacilo, afetando o transporte de nutrientes. A detecção precoce da resistência aos fármacos é muito importante para o controle da tuberculose e para o início do tratamento adequado. No entanto, o método das proporções em Lowenstein-Jensen (L-J), rotineiramente utilizado no Brasil para detecção de resistência em M. tuberculosis é trabalhoso, demanda tempo para obtenção dos resultados, além de possuir baixa reprodutibilidade em pH baixo, necessário para realização do teste contendo PZA. Dessa forma, o objetivo do presente estudo foi padronizar e avaliar o uso da Técnica em microplaca utilizando Resazurina como agente revelador (REMA) para detecção de resistência à PZA em M. tuberculosis. O resultado deste trabalho está no artigo: "Aplicação do método em microplaca utilizando resazurina (REMA- Resazurin Microtiter Assay) para detecção de resistência em Mycobacterium tuberculosis", que mostra como o método REMA proposto pode contribuir para a detecção rápida de resistência a PZA em M. tuberculosis, por uma técnica rápida, sensível e específica.37
