Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The Proper Basis for Zero-dimensional Polynomial Ideals
零维 多项式理想 正确基 Grobner基
2023/11/29
The Grobner basis for a zero-dimensional polynomial ideal comprises a univariate polynomial in the least variable. The elimination process in Buchberger's algorithm unnecessarily involves the least va...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：μ-basis for a tensor product rational surface with respect to one variable
张量积 有理曲面 变量 μ基
2023/4/28
The method of moving planes and moving quadrics expresses the implicit equation of a rational parametric surface as a compact determinant. Efficient computation of the moving planes and moving quadric...
Genomic analyses reveal the genetic basis of early maturity and identification of loci and candidate genes in upland cotton (Gossypium hirsutum L.)
陆地棉 全基因组 重测序方法 SNP变异图谱
2024/5/17
本研究利用收集的436份国内外变异广泛的陆地棉材料，采用全基因组重测序方法，构建了群体的SNP变异图谱，通过对包含136份早熟棉资源在内的356份陆地棉材料进行深度重测序，并结合公共数据库中的80份陆地棉材料共获得了10,118,884个高质量的SNPs。利用全基因组关联分析（GWAS）鉴定到控制陆地棉早熟性的307个显著遗传位点和重要调控基因。两个早熟遗传热点区域位于 D03和A05&...

New insights genetic basis bird migration
2019/10/18
A gene associated with the migratory patterns of golden-winged and blue-winged warblers could lend insight into the longstanding question of how birds migrate across long distances.A new study led by ...
400 million years of a stable relationship:clues to the molecular basis of balance in AM symbiosis
400 million years stable relationship molecular basis of balance AM symbiosis
2017/4/27
Walking through a grassy field or forest take a moment to consider what lies beneath the surface. A web of plant roots interacts symbiotically with arbuscular mycorrhizal (AM) fungi that extend their ...
Gordon Research Conference on Molecular Basis of Microbial One-Carbon Metabolism
Molecular Basis Microbial One-Carbon Metabolism
2016/7/29
Metabolism of one-carbon (C1) compounds is shared by all living organisms today, yet microorganisms growing on one-carbon compounds established C1 metabolism as a major driver of global elemental cycl...
Decoy-state quantum key distribution with biased basis choice
Decoy-state quantum distribution biased basis choice
2016/1/23
Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commercialization, but many...

Entanglement-based quantum key distribution iased basis choice via free space
2016/1/23
We report a free-space entanglement-based quantum key dis-tribution experiment, implementing the biased basis protocol between two sites which are 15.3 km apart. Photon pairs from a polarization-entan...
Protein evolution in two co-occurring types of Symbiodinium: an exploration into the genetic basis of thermal tolerance in Symbiodinium clade D
Symbiodinium Thermal tolerance Coral
2015/12/11
The symbiosis between reef-building corals and photosynthetic dinoflagellates (Symbiodinium) is an
integral part of the coral reef ecosystem, as corals are dependent on Symbiodinium for the majority ...
Best-basis analysis of broadband tremor signals
adaptive spectrogram analysis broadband tremor
2015/10/8
Active volcanoes usually generate highly non-stationary broadband tremor signals. Short-time shock events with a frequency content of several decades are superimposed on a stationary narrow band conti...
Australian paleoseismology: towards a better basis for seismic hazard estimation
intraplate seismicity seismic hazard Australia paleoseismology
2015/9/16
Probabilistic seismic hazard analyses in Australia rely fundamentally on the assumption that earthquakes recorded in the past are indicative of where earthquakes will occur in the future. No attempt h...
