When a star swallows a planet, does it belch? Leave crumbs? Get bigger? No one could say for sure because no one had witnessed it — until now.
近日,中国地质大学地质过程与矿产资源国家重点实验室赵来时教授团队在Nature Index 杂志——《Earth and Planetary Science Letters》发表题为《晚二叠纪末生物大绝灭及早三叠生物复苏时期全球的汞循环》(Global mercury cycle during the end-Permian mass extinction and subsequent Early...
The asteroid impact 66 million years ago that ushered in a mass extinction and ended the dinosaurs also killed off many of the plants they relied on for food. Fossil leaf assemblages from Patagonia su...
Superstorm Sandy brought flood levels to the New York region that had not been seen in generations. Causing an estimated $74.1 billion in damages, Sandy was the fourth costliest U.S. storm behind Hurr...
Valley fever is endemic to hot, dry regions such as California's San Joaquin Valley in the southwestern United States, but scientists at the University of California, Irvine predict that climate chang...
近日,地学《Earth-Science Reviews》正式刊发了中国地质大学生物地质与环境地质国家重点实验室陈中强教授团队《古特提斯洋北缘下三叠统特殊的微生物席底质生物相及其对大灭绝之后生物复苏的指示意义》(Unusual shallow marine matground-adapted benthic biofacies from the Lower Triassic of the north...
近日,中国地质大学地质过程与矿产资源国家重点实验室赵来时教授团队在国际著名期刊《Earth and Planetary Science Letters》发表题为《晚二叠生物大绝灭期间的汞富集—来自华南浅海与深水相剖面的记录》(Mercury anomalies across the end Permian mass extinction in South China from shallow an...
New findings published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) by Desert Research Institute (DRI) Professor Joseph R. McConnell, Ph.D., and ...
This paper shows that the performance of a Gaussian Mixture Model using a Universal Background Model (GMM-UBM) speaker verification (SV) system can be further improved by combining it with threshold a...
The first deep seismic sounding experiment in Northwestern Anatolia was carried out in October 1991 as part of the "German - Turkish Project on Earthquake Prediction Research" in the Mudurnu area of t...
The dead-end depth of an element g of a group with finite generating set A is the distance from g to the complement of the radius d(1,g) closed ball, in the word metric d. We exhibit a finitely presen...
The dead-end depth of an element g of a group G with generating set A is the distance from g to the complement of the radius d(1,g) closed ball, in the word metric d defined with respect to A. We exhi...
Although scientists have long believed that, in an eastern boundary current system, alongcoast wind stress is responsible for the upwelling of deep nutrients that initiates phytoplankton blooms, the C...
Many oceanographic products are currently being disseminated in a systematic and routine manner to end users. In recent years, data producers have gained insight into the specific requirements of the ...
End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the North...
