Frames, Corpora and Knowledge Representation
No full textThis volume hosts contributions which focus on a wide variety of
cognitive and linguistic aspects of the frame problem, thus
highlighting the alternative and complementary features that
characterize the concept of “frame”. Cognitive operations and
conceptualization processes are described in their dynamic principles; contrastive semantic analyses are carried out and illustrated; the possibility of (automatically) identifying frame elements through surface corpus data are explored together with computational approaches to the problem of lexical access.
The innovative methodological approaches brought out by these
perspectives are illustrated by means of tools and resources available for the analysis of Italian corpus data and for the study of the contemporary and modern history of the Italian language.

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
PELAKSANAAN PEMBAGIAN WARIS PADA MASYARAKAT MUSLIM KELURAHAN TANJUNG REMA DARAT KECAMATAN MARTAPURA KABUPATEN BANJAR KALIMANTAN SELATAN
No full textThis research aims to identify the inheritance distribution implementation
among the Moslem community of Tanjung Rema Darat ward and the
understanding of Tanjung Rema Darat ward community regarding the Islamic
inheritance jurisprudence.
This was an empirical or sociological research. Subjects were recruited
through the use of non random sampling technique with purposive samples taken
based on the specific requirements that should be met. The gathered data from the
field study and literature study where quantitatively and qualitatively analyzer and
descriptively written.
Result of this research show that the implementation of inheritance
distribution among the Moslem community of Tanjung Rema Darat ward
adopting Islamic inheritance jurisprudence, which has been implemented based on
the Islamic inheritance jurisprudence. The Islamic Inheritance Jurisprudence
adopted in the inheritance distribution process involve faraid, islah, and faraidislah.
This is consistent with the bilateral principle, meaning that the heir is
awarded with the rights or the inheritance share from the two parties. The
understanding of Tanjung Rema Darat ward people on Islamic Inheritance
jurisprudence is quite good, in which the inheritance distribution has been
implemented based on the Islamic Inheritance Jurisprudence. This was indicated
by the analysis showing that among the responses of 150 respondents, more than
50% of them provided correct answers. The understanding of Tanjung Rema
Darat ward community concerning the shares that the heir receives based on
Islamic Inheritance Jurisprudence has been still lower. This was identified from
the respondents "answers on the author" questions regarding the shares of the
widower heir and widow in case the inheritance giver does not have a child and
the maximum share of inheritance with no agreement from the heir

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

Environmental Regulations, Air and Water Pollution, and Infant Mortality in India
No full textUsing the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of India's environmental regulations. The air pollution regulations were effective at reducing ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide. The most successful air pollution regulation is associated with a modest and statistically insignificant decline in infant mortality. However, the water pollution regulations had no observable effect. Overall, these results contradict the conventional wisdom that environmental quality is a deterministic function of income and underscore the role of institutions and politics.
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
Validation of the REMA score for predicting mast cell clonality and systemic mastocytosis in patients with systemic mast cell activation symptoms
No full text[Background]: A variable percentage of patients with systemic mast cell (MC) activation symptoms meet criteria for systemic mastocytosis (SM). We prospectively evaluated the clinical utility of the REMA score versus serum baseline tryptase (sBt) levels for predicting MC clonality and SM in 158 patients with systemic MC activation symptoms in the absence of mastocytosis in the skin (MIS). [Methods]: World Health Organization criteria for SM were applied in all cases. MC clonality was defined as the presence of KIT-mutated MC or by a clonal HUMARA test. The REMA score consisted of the assignment of positive or negative points as follows: male (+1), female (–1), sBt 25 µg/l (+2), presence (–2) or absence (+1) of pruritus, hives or angioedema and presence (+3) of presyncope or syncope. Efficiency of the REMA score for predicting MC clonality and SM was assessed by receiver operating characteristic (ROC) curve analyses and compared to those obtained by means of sBt levels alone. [Results]: Molecular studies revealed the presence of clonal MC in 68/80 SM cases and in 11/78 patients who did not meet the criteria for SM. ROC curve analyses confirmed the greater sensitivity and a similar specificity of the REMA score versus sBt levels (84 vs. 59% and 74 vs. 70% for MC clonality and 87 vs. 62% and 73 vs. 71% for SM, respectively). [Conclusions]: Our results confirm the clinical utility of the REMA score to predict MC clonality and SM in patients suffering from systemic MC activation symptoms without MIS.Peer Reviewe
