For decades, astrophysicists have encountered a puzzling contradiction: although many galactic-wind models—simulations of how matter is distributed in our universe—predict that the majority of the "no...
Some 30 years ago, astronomers found that regions of ionized gas around young high mass stars remain small (under a third of a light-year) for ten times longer than they should if they were to expand ...
Investigation on flame retardancy, combustion and pyrolysis behavior of flame retarded unsaturated polyester resin with a star-shaped phosphorus-containing compound
Unsaturated polyester resin Thermal degradation Pyrolysis evolved gas analysis Flame retardancy
2015/3/24
The phosphorus-containing star-shaped flame retardant (TRIPOD-DOPO) was synthesized, while the
flame retardant unsaturated polyester resins (FR-UPRs) composites with various amounts of TRIPODDOPO wer...
Perturbing E®ects of a Close Star on Relativistic Precessions of a Star in Galactic Center
black hole physics Galaxy:center relativity
2013/4/9
As proposed by Cli®ord M.Will, observations of the precessing orbits of a class of stars around the supermassive black hole in the galactic center with very short period(O(0:1) yr) could provide ...
star forest is a collection of vertex-disjoint trees of depth at most 1, and its size is the number of leaves in all its components. A spanning star forest of a given graph G is a spanning subgraph of...

PLEIADES is the highest resolution civilian earth observing system ever developed in Europe. This imagery program is conducted by the French National Space Agency, CNES. It has been operating since 20...
An AUTONOMOUS STAR IDENTIFICATION ALGORITHM BASED ON THE DIRECTED CIRCULARITY PATTERN
Angular distance Matching probability Matching group Directed circularity pattern The longest matching chain
2014/4/25
The accuracy of the angular distance may decrease due to lots of factors, such as the parameters of the stellar camera aren't calibrated on-orbit, or the location accuracy of the star image points is ...
Eigenvalue distributions from a star product approach
Eigenvalue distributions star product approach Mathematical Physics
2012/6/21
We use the well-known isomorphism between operator algebras and function spaces equipped with a star product to study the asymptotic properties of certain matrix sequences in which the matrix dimensio...
Asymptotics of the critical non-linear wave equation for a class of non star-shaped obstacles
Asymptotics the critical non-linear wave equation non star-shaped obstacles Analysis of PDEs
2012/6/14
Scattering for the energy critical non-linear wave equation for domains exterior to non trapping obstacles in 3+1 dimension is known for the star-shaped case. In this paper, we extend the scattering f...
Species tree inference by the STAR method, and generalizations
Species tree inference STAR method generalizations Populations and Evolution
2012/5/2
The multispecies coalescent model describes the generation of gene trees from a rooted metric species tree, and thus provides a framework for the inference of species trees from sampled gene trees. We...
Generalized Measures of Edge Fault Tolerance in (n,k)-star Graphs
Combinatorics fault-tolerant analysis (n, k)-star graphs edge-connectivity h-super edge-connectivity
2012/4/18
This paper considers a kind of generalized measure $\lambda_s^{(h)}$ of fault tolerance in the $(n,k)$-star graph $S_{n,k}$ for $2\leqslant k \leqslant n-1$ and $0\leqslant h \leqslant n-k$, and deter...

2012/4/18
Let $F$ be a homogeneous polynomial in $S = \mathbb{C}[x_0,...,x_n]$. Our goal is to understand a particular polynomial decomposition of $F$; geometrically, we wish to determine when the hypersurface ...
Discovery of the neutron star spin and orbital period from the Be/X-ray binary IGR J05414-6858 in the LMC
