Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Researches on manifolds with scalar curvature bounded from below
标量曲率 有界 流形
2023/4/25
The motivation to study manifolds with scalar curvature bounded from below comes from Mathematical General Relativity and Riemannian Geometry. In this talk, I'll first briefly introduce some problems ...
Scientists studied microorganisms from an underwater mountain in the Atlantic Ocean, pioneering a method that could open new windows into our understanding of how life survives deep under the sea -- o...
How hot is too hot for life deep below the ocean floor?（图）
How hot life deep below ocean floor
2020/12/18
At what depth be-neath the seabed does it be-come so hot that mi-cro-bial life is no longer possible?An ex-ped-i-tion by In-ter-na-tional Ocean Dis-cov-ery Pro-gram scientists has provided new insight...
Microbial diversity below the seafloor is as rich as on Earth's surface（图）
Microbial seafloor rich Earth's surface
2020/10/30
For the first time, researchers have mapped the biological diversity in marine sediment, one of Earth's largest global biomes. Although marine sediment covers 70% of Earth's surface, little was known ...
Grooving of a grain boundary by evaporation–condensation below the roughening transition
grain boundary evaporation–condensation below roughening transition
2015/10/16
The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–c...
A bound from below for the temperature in compressible Navier-Stokes equations
below for the temperature compressible Navier-Stokes equations
2015/10/15
We consider the full system of compressible Navier-Stokes equations for heat conducting fluid. We show that the temperature is uniformly positive for t ≥ t0 (for any t0 > 0) for any solutions with fin...
Coupling from below as a source of ionospheric variability: a review
Lower atmosphere ionospheric response waves thermosphere
2015/9/25
The purpose of this paper is to review shortly some observational backgrounds for the suggestion of a genuine link between processes in the lower atmosphere and ionospheric response. Attention is conc...
Below the Salt Marsh Surface: Visualization of Plant Roots by Computer-Aided Tomography
Computer-Aided Tomography Salt Marsh Surface
2015/7/16
As sea level rises, salt marshes become subtidal mudflats unless soil surface accretion occurs at rates fast enough to keep the marsh from being submerged (Brinson et al., 1995). The individual proces...
New study shows Antarctic ice shelf is thinning from above and below（图）
Antarctic ice shelf above below
2015/5/25
The Larsen C Ice Shelf—whose neighbours Larsen A and B, collapsed in 1995 and 2002—is thinning from both its surface and beneath, according to an international study published in the journal The ...
Development of a new semi-empirical parameterization for below-cloud scavenging of size-resolved aerosol particles by both rain and snow
new semi-empirical parameterization rain
2014/12/18
t. A parameter called the scavenging coefficient 3
is widely used in aerosol chemical transport models (CTMs)
to describe below-cloud scavenging of aerosol particles by
rain and snow. However...
Diel and lunar cycles of vertical migration extending to below 1000 m in the ocean and the vertical connectivity of depth-tiered populations
Diel and lunar cycles vertical migration extending below 1000 m the ocean the vertical connectivity depth-tiered populations
2014/4/2
We measured diel migration with 11 acoustic Doppler current meter profilers and consistently found diel and lunar cycles of vertical migration from 250 m down to the bathypelagic (> 1000 m). These mea...
Comparative study on humic substances isolated in thermal groundwaters from deep aquifers below 700 m
Pannonian Basin thermal water geothermal energy deep aquifer aquatic humic substances
2017/4/11
Main objectives of this study were to investigate whether humic substances (HS) exist in hot groundwater from deep
basinal aquifers waters and to provide basic knowledge on humic (HA) and fulvic acid...
Probing Asthenospheric Density, Temperature, and Elastic Moduli Below the Western United States
Probing Asthenospheric Density Temperature Elastic Moduli Below the Western United States
2014/4/9
Periodic ocean tides continually provide a cyclic load on Earth’s surface, the response to which can be exploited to provide new insights into Earth’s interior structure. We used geodetic observations...
Petrography and geochemistry of accreted oceanic fragments below the Western Cordillera of Ecuador
Ecuador Western Cordillera accreted oceanic terranes exhumation
2017/4/12
The Western Cordillera of Ecuador consists of Cretaceous crustal fragments of oceanic plateaux and superimposed
insular arcs, which were accreted to the northwestern South American margin during the ...
$L^2$-norm and estimates from below for Riesz transforms on Cantor sets
$L^2$-norm estimates from below Riesz transforms Cantor sets
2011/1/18
The aim of this paper is to estimate the L2-norms of vector-valued Riesz trans-forms Rs
and the norms of Riesz operators on Cantor sets in Rd, as well as to study the distribution of values of Rs ...
