Observing Broadband Tsunamis in Deep Water Via Distributed Acoustic Sensing

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Tsunamis have been detected as strain variations in optical fibers of submarine cables through distributed acoustic sensing (DAS). However, the usefulness of strain variations during tsunamis for early warning remains unclear. Here, we compare fiber strains and sea‐level changes for both infragravity waves in ambient noise and tsunamis ...

Structure Heterogeneity Around the Western End of the 1999 Izmit Earthquake Rupture Revealed by Distributed Acoustic Sensing

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract We use distributed acoustic sensing along a submarine fiber‐optic cable to provide the first high‐resolution two‐dimensional shear‐wave velocity (Vs) model of the North Anatolian Fault (NAF) in the Marmara Sea. Using 7 days of ambient noise recordings, we extract Scholte wave dispersion curves via slant‐stacking and invert for the Vs structure,

Frequency Dependent Microseisms Sources: A Case Study in Oregon

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The origin of microseisms—whether from deep‐ocean sources or coastal reflections—has been debated for decades. In this study, we use Distributed Acoustic Sensing (DAS) and Ocean Bottom Seismometer data collected offshore Oregon to investigate microseisms sources across a range of frequency bands. Our results reveal a clear frequency dependence:

Da urgência da reinvenção da escola

open access: yesEduca, 2018
Os esforços para renovar a qualidade dos processos e dos resultados escolares foram uma constante ao longo do século XX. Teorias, projetos, movimentos, reformadores sempre viram os seus objetivos limitados porque o modelo escolar [a gramática escolar, isto é, o modo de organizar o conhecimento, os espaços, os tempos, o agrupamento de alunos, a alocação

Estimating Focal Mechanism of Small Earthquakes Using S/P Amplitude Ratios of Distributed Acoustic Sensing Records

open access: yesGeophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract We proposed a method for estimating focal mechanisms based on S/P amplitude ratios from distributed acoustic sensing (DAS) records for single earthquakes and successfully obtained the mechanisms from four events. This method involves measuring the maximum amplitude ratio between the S‐ and P‐waves of the DAS records, followed by searching for ...

Da saída: religião da saída da religião, arte da saída da arte

open access: yesREVER - Revista de Estudos da Religião, 2018
Neste ensaio, procurarei compreender a recusa da sacralização da arte – e a negação do museu como lugar de culto dessa nova religião –, partindo de uma análise de um movimento religioso que se caracteriza por ter recusado o antigo sagrado e negado as formas elementares da religião arcaica: o cristianismo.

A Consistência das Memórias da Infância [PDF]

open access: yesPsicologia: Teoria e Pesquisa, 2016
Resumo A coleta de relatos retrospetivos constitui um procedimento frequente em psicologia. Neste estudo, analisou-se, em uma amostra de adultos jovens não institucionalizados, a consistência desses relatos sobre diversas experiências da infância (vitimação, medos, dificuldades de aprendizagem), confrontando-os com os relatos atuais dos seus pais e/ou ...

DASEventNet: AI‐Based Microseismic Detection on Distributed Acoustic Sensing Data From the Utah FORGE Well 16A (78)‐32 Hydraulic Stimulation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Distributed acoustic sensing (DAS) has emerged as a promising seismic technology for monitoring microearthquakes (MEQs) with high spatial resolution. Efficient algorithms are needed for processing large DAS data volumes. This study introduces a deep learning (DL) model based on a Residual Convolutional Neural Network (ResNet) for detecting ...

FILOSOFIA DA ANÁLISE DA ESTABILIDADE DA LIQUIDEZ

open access: yesRevista Catarinense da Ciência Contábil, 2005
A informação foi considerada finalidade de nosso conhecimento, até o período em os pensadores e pesquisadores da contabilidade passaram a raciocinar sobre o conteúdo e o significado dos informes. Nesta busca da razão sobre os estados patrimoniais, surgiu a análise contábil que procura por meio de relações e identidades, o significado da dinâmica ...
