Credible historical land use/cover data are very important for past global change research. This study generates a set of integrated reconstruction methods based on multisource and produces new improved cropland sets in Europe over the 200 years. For AD 2000, FAO data, existing research results statistical integrated. 1900, method integrating two independent agricultural by correction validatio...

INTRODUCTION We analyzed trends in US female mortality rates by decade from 1900 through 2010, assessed age and racial differences, and proposed explanations and considered implications. METHODS We conducted a descriptive study of trends in mortality rates from major causes of death for females in the United States from 1900 through 2010. We analyzed all-cause unadjusted death rates (UDRs) fo...

Predictions of the remainder of the season’s Atlantic basin tropical cyclone activity from 1 August have been issued by Gray and his colleagues at the Tropical Meteorology Project at Colorado State University since 1984. The original 1 August prediction scheme utilized several predictors, including measures of the stratospheric quasi-biennial oscillation (QBO), West African rainfall, El Niño–So...

We report the discovery of complex high frequency variability during the August 27, 1998 giant flare from SGR 1900+14 using the Rossi X-ray Timing Explorer (RXTE). We detect an ≈ 84 Hz oscillation (QPO) during a 1 s interval beginning approximately 1 min after the initial hard spike. The modulation amplitude is energy dependent, reaching a maximum of 26% (rms) for photons above 30 keV, and is n...

In this paper we call attention to the identity of the type species of Thiodina Simon, 1900, T. nicoleti Roewer, 1951. When Simon proposed the genus, he characterized it based on morphological features found in species he described, but not found in the type species he designated, and whose type specimens, apparently, he had not examined. Nicolet's original description makes it clear that the t...

This paper discusses parametric, nonparametric, and semiparametric models of urban growth. To illustrate differences across approaches, we test Gibrat's law in the long run, using three methods different datasets: Spanish capital cities regions (1900–2011, annual data) US MSAs (1900–2000, decennial data). Our results reveal that estimation relationship between growth initial size can significan...

Abstract We present an overview of tsunami occurrences based on analysis a global database tsunamis for the period 1900–2020. evaluate geographic and statistical distribution various source mechanisms, high-fatality tsunamis, maximum water heights (MWHs) possible biases in observation recording events. enhance with case studies from Indonesia, where are generated diverse range sources, includin...
