One can elucidate integrability properties of ODEs by knowing the existence of second integrals. However, little is known about how they are preserved, if at all, under numerical methods. In this talk...
近日,中国地质大学资源学院博士生苟启洋在国际著名能源地质学期刊《Energy》上刊发研究成果,该成果主要揭示了构造作用和保存条件对富有机质页岩微纳米孔隙发育演化的控制作用,探讨了不同孔隙结构背景下页岩储层压裂改造效果。
A critical survival decision for all animals is when, where and how to escape from a looming threat. A Northwestern University research team using multi-neuron imaging has learned that the escape resp...
Treasure Caretaker Training (Digital Monastery Project), teaches Buddhist monks, nuns and community cultural caretakers to protect and preserve their own monastery sacred art treasures. Participants l...
The crisis management of a disaster, whether caused naturally or by human action, requires a thorough knowledge of the territory involved, with regard to both its terrain and its developed areas. The...
The STRATAFORM research program (Nittrouer and Kravitz, 1995) consists of three interrelated areas of multidisciplinary research (Nittrouer and Kravitz, 1996, this issue). The "stratigraphic sequences...
With the recent developments in three-dimensional (3-D) scanner technologies and photogrammetric techniques, it is now possible to acquire and create accurate models of historical and archaeological...
Consider a coastal storm that mobilizes and transports enough sediment on the continental shelf to produce a distinctive deposit in the seabed that escapes significant reworking before it is buried by...
The Usumacinta basin is characterized by aboundance of natural and scenic resources. It also houses a vast biodiversity (wich also means invaluable genetic resources). Its river is the longest in Mex...
The main input of phosphorus to the ocean is associated with river runoff, while this element leaves the marine system via burial in the sediments. Solid phase P accumulation is a function of bottom ...
New CNMNC guidelines are established, in order to standardize the use of prefixes and suffixes in mineral nomenclature,and to preserve historical names. The recommendations for the use of suffixes are...
Korean Ministry of Environment (MoE) has implicated regulations to determine if the levels of environmental contaminants exceed regulations levels. The Korean MoE adopted a partial extraction method ...
Clay minerals possess sorptive capacities for organic and inorganic matter, including DNA (Lorenz and Wackernagel, 1994), and hence reduce the utilization and degradation of organic matter or DNA by m...
Sequestration of organic matter (OM) in sediments is a fundamental biogeochemical process that regulates planetary temperature, the flux of free oxygen to the atmosphere and oceans, and the distributi...
Abstract: Kagan and Shepp (2005, Amer. Statist.) presented an elegant example of a mixture model for which an insufficient statistic preserves Fisher information. This note uses the regularity propert...
