Eurasia-Africa plate boundary region yields new seismographic data

Seismographic Data Compression --Applying Modified Tunstall Coding--

The Standard for the Exchange of Earthquake Data (SEED) is a commonly used file format in the seismology field. Steim1 and Steim2 compression schemes, i.e. lossless data compressions, are used in SEED format and are written in Data Description Language (DDL), which has computational limitations making it difficult to implement many standard compression algorithms. Steim1 and Steim2 are fixed co...

Africa's Place in Globalization: Africa, Eurasia, and Their Borderlands

Africa is commonly marginalized in global social studies, whether of present or past. This essay makes the case for the substantial importance of Africa through a systematic comparison with Eurasia. It documents the large area and the relatively dense population of Africa, in past and present, as compared with Eurasia and also with the Americas. The essay gives particular attention both to sub-...

Lithospheric deformation in the Africa-Iberia plate boundary: Improved neotectonic modeling testing a basal-driven Alboran plate

We present an improved neotectonic numerical model of the complex NW Africa-SW Eurasia plate boundary segment that runs from west to east along the Gloria Fault up to the northern Algerian margin. We model the surface velocity field and the ongoing lithospheric deformation using the most recent version of the thin-shell code SHELLS and updated lithospheric model and fault map of the region. To ...

RTLS yields new data for managing patient logistics.

A New Tree Cover Percentage Map in Eurasia at 500 m Resolution Using MODIS Data

Global tree cover percentage is an important parameter used to understand the global environment. However, the available global percent tree cover products are few, and efforts to validate these maps have been limited. Therefore, producing a new broad-scale percent tree cover dataset is valuable. Our study was undertaken to map tree cover percentage, on a global scale, with better accuracy than...
