Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Microphysical and non-thermal processes in the circumgalactic medium: turbulence, magnetic fields and cosmic rays
银河系 周介质 微物理 非热过程 湍流 磁场 宇宙射线
2023/4/18
Multiphase gas structure is ubiquitous in our universe. Recent observations suggest that large quantities of cool (10^4 K) gas are detected in the circumgalactic medium (CGM) of galaxy halos, which ex...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The core-shell obstacle scattering in a multilayered medium
多层介质 核壳障碍物 散射 边界积分方程
2023/4/26
Scattering from the coated targets embedded in a multilayered medium has attracted much interest during recent years for extensive applications, such as sea radar target detection and underwater radar...
Impact of interspecific hybridization of T. pratense × T.medium and backcrossing on genetic variability of progeny
cytology FISH hybrids rDNA red clover zigzag clover
2016/12/8
Red clover (Trifolium pratense L.) is a high-quality fodder crop which has been hybridized successfully with its wild relative zigzag clover (T. medium L.). The aim of this study was to evaluate the g...
ESTIMATION OF AERODYNAMIC ROUGHNESS AND ZERO PLANE DISPLACEMENT USING MEDIUM DENSITY OF AIRBORNE LIDAR DATA
Airborne LiDAR Aerodynamic Roughness Length Zero Plane Displacement Forest
2016/10/14
This paper presents a framework to estimate aerodynamic roughness over specific height (zo/H) and zero plane displacement (d/H) over various landscapes in Kelantan State using airborne LiDAR data. The...
Relations between morphological settings and vegetation covers in a medium relief landscape of Central Italy
hyperspectral data vegetation mapping geomorphology classification methods
2015/9/7
Mount area, a medium relief structure within the Italian Latium region. The study aims at defining the relationships between vegetation and landform types and highlighting the main morphological chara...
Searching for the effects of the May-June 2012 Emilia seismic sequence (northern Italy):medium-depth deformation structures at the periphery of the epicentral area
Emilia 2012 earthquake Seismic effect Faulting Seismic reflection survey
2015/8/26
In 2012, a seismic sequence occurred in the lowlands of the Emilia-Romagna Region (northern Italy), between the borders of the Modena, Ferrara and Bologna Provinces. It consisted of seven mainshocks (...
Peristaltic flow of a Newtonian fluid through a porous medium in a vertical tube under the effect of a magnetic field
Heat Transfer Magnetic Field Newtonian Fluid Porous Medium Reynolds Number
2015/7/21
In this paper, we studied the effects of heat transfer and magnetic field with peristaltic flow of a viscous incompressible Newtonian fluid through a porous medium in a vertical tube under the assumpt...
Time splitting for the Liouville equation in a random medium
Time splitting Liouville equation random medium
2015/7/14
We consider the Liouville equations with highly heterogeneous Hamiltonians and their numerical solution by a time splitting algorithm. Such equations model the density of particles evolving according ...
Traveling waves in a one-dimensional heterogeneous medium
Traveling waves one-dimensional heterogeneous medium
2015/7/14
We consider solutions of a scalar reaction-diffusion equation of the ignition type with a random, stationary and ergodic reaction rate. We show that solutions of the Cauchy problem spread with a deter...
This paper reviews several mathematical techniques that have been developed to analyze the asymptotic behavior of waves and particles propagating in a heterogeneous medium. The heterogeneous medium is...
The logarithmic delay of KPP fronts in a periodic medium
logarithmic delay KPP fronts periodic medium
2015/7/14
We consider solutions of the KPP-type equations with a periodically varying reaction rate, and compactly supported initial data. It has been shown by Bramson [5, 6] in the case of the constant reactio...
The ameliorative effec t of silicon on soybean see dlings grown in potassium- deficient medium
Antioxidant enzyme activities oxidative stress potassium deficiency silicon soybean Glycine max
2015/2/5
Background and Aims Crop yield and nutritional quality are significantly reduced when potassium (K) in soil is deficient. As a beneficial element for plants, silicon (Si) is effective in alleviating t...
Metal enrichment of the intergalactic medium at z=3 by galactic winds
galactic winds intergalactic medium
2014/12/26
Studies of quasar absorption lines reveal that the low-density intergalactic medium (IGM) at z ~ 3 is enriched to between 10-3 and 10-2 solar metallicity. This enrichment may have occurred in an early...
