Partial Rigidity of CR Embeddings of Real Hypersurfaces into Hyperquadrics with Small Signature Difference
Partial Rigidity Real Hypersurfaces Signature Difference
font style='font-size:12px;'>
2010/11/11
We study the rigidity of holomorphic mappings from a neighborhood of a Levi-nondegenerate CR hypersurface $M$ with signature $l$ into a hyperquadric $Q_{l'}^{N} \subseteq \mathbb{CP}^{N+1}$ of larger ...
Lyman `bump' galaxies - II. A possible signature of massive extremely metal-poor or metal-free stars in z=3.1 Ly-alpha emitters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/29
Deep NB359 imaging with Subaru by Iwata et al. have detected surprisingly strong Lyman continuum (LyC; ~900A in the rest-frame) from some LAEs at z=3.1. However, the redshifts might be misidentified d...
A distinct peak-flux distribution of the third class of gamma-ray bursts: A possible signature of X-ray flashes?
High Energy Astrophysical Phenomena (astro-ph.HE) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2010/12/28
Gamma-ray bursts are the most luminous events in the Universe. Going beyond the short-long classification scheme we work in the context of three burst populations with the third group of intermediate ...

Decoherence as a signature of an excited state quantum phase transition
Decoherence excited state quantum phase transition
font style='font-size:12px;'>
2010/3/10
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presenc...

A precursory ULF signature the Chi-Chi earthquake Taiwan
font style='font-size:12px;'>
2009/12/9
ULF emission data at Lunping (epicentral distance, 120 km) have been analysed for the Chi-Chi earthquake (with magnitude 7.6 and depth of 11 km) in Taiwan which occurred on 21 September 1999. Simple i...
Lithocodium and Bacinella signature of a late Hauterivian,local microbial event:the Urgonian limestone in South-East France
Lithocodium Bacinella Urgonian automicrite dolomite Hauterivian Jura Pre-Subalpine Domain
font style='font-size:12px;'>
2009/12/7
Sediment binding crusts of Lithocodium aggregatum and associated Bacinella irregularis abound in a shallow water limestone layer, in South-East France. The sudden appearance of these crusts denotes a ...
Signature Inversion in Oddodd Nuclei
Nuclei Signature Inversion
font style='font-size:12px;'>
2009/10/28
Signature inversion in oddodd nuclei is investigated by using a proton and a neutron coupling to the coherent state of the core. Two parameters are employed in the Hamiltonian to set the energy sc...
Noble gas signature of the late heavy bombardment in the Earth's atmosphere
Noble gas signature late heavy bombardment Earth's atmosphere
font style='font-size:12px;'>
2009/10/22
The Lunar cratering record is consistent with the occurrence of a late heavy bombardment (LHB), which marked the end of terrestrial planet accretion 3.8 billion years ago. However, clear evidence of a...

2009/10/21
New insights into the Sun's chemical composition may provide a new way to search for Earth-like planets orbiting distant stars – claims an international team of astrophysicists.Astronomers have alread...
A possible signature of new physics at BES-Ⅲ
BES-Ⅲ decay constant QCD leptonic decay
font style='font-size:12px;'>
2009/8/17
The recent observations of the purely leptonic decay Ds+→μ+νμ and τ+ντ at CLEO-c and B factory may allow a possible contribution from a charged Higgs boson. One such measurement of the decay constant ...
High-spin states and signature inversion studies in 110Ag

2009/8/14
The high-spin states of 110Ag were populated via fusion evaporation reaction 110Pd(7Li, 2p2n)110Ag and a new level scheme has been presented. The systematics of signature splitting and signature inver...

2009/7/7
既考虑到脱耦合效应而进行双带分析,又进行通常的单带分析,对A≈190核区奇质量核的signature伙伴带的自旋指定做了讨论并给出了明确结果.在具体的计算中,不拘泥在I(I+1)展开式中究竟取几项,而是着重看其收敛过程,并在此基础上用物理量拟合法和带首转动惯量系统学方法进行综合分析.

Frost flower chemical signature winter snow Vestfonna ice cap
font style='font-size:12px;'>
2010/2/3
The chemistry of snow and ice cores from Svalbard is influenced by variations in local sea ice margin and distance to open water. Snow pits sampled at two summits of Vestfonna ice cap (Nordaustlandet,...
