... specadd creates a multiple X-ray spectrum FITS file by stacking or putting together (``adding'') two single spectrum files. ... This type of spectral files is particularly useful when the user wants to simultaneously analyse different observations of the same object carried out with the same instrument or with different instruments. ... The Data extension for a multiple spectral dataset stores one single spectrum per row, instead of one channel per row as it is the case of single spectrum files. ...

... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...

... Rigid tensor categories (with an associative and commutative tensor product) can be viewed as a generalization of algebraic groups (the case where a fiber functor exists). Super groups give other examples. Over an algebraically closed field and under the finiteness condition ``for some self dual generator $X$, the length of the $N^{\text{\rm th}}$ tensor power of $X$ is at most polynomial in $N$'', no other example is known. ...

The xpamb program can act as a "classical" message bus interface between clients and servers. A client can send a data request to the message bus, which then interfaces with multiple servers and returns the data back to the client. ... For example, if the -info switch is used: xpaget xpamb -info foo then the info about that stored data buffer will be returned. If the -data is used with a specific name: xpaget xpamb -data foo then the stored data itself will be returned. ... data [name] . ...

... Email: chaos@mail.cplire.ru . ... We investigate phenomena on the edge of spatially homogeneous chaotic mode and spatiotemporal chaos in a lattice of chaotic 1-D maps with local connections. We show that spatially homogeneous chaotic mode cannot exist in a lattice with local connections if the Lyapunov exponent of the isolated chaotic map is greater than some critical positive value. We propose a few schemes that make spatial synchronization possible in large lattices. ...

. Mars was imaged in great detail in 2005. New research indicates Earth's core formed under different conditions from those that existed on Mars. One possible explanation for this is the difference in mass between the two planets. With Earth being eight times larger than Mars, the pressure of core-formation could be higher. Different silicate phases also may have been involved. NASA/JPL/USGS

Next: Initial conditions Up: Old neutron star distribution Previous: Introduction . The problem to be solved is to find stationary space distribution of stars which have had certain initial space and velocity distributions and move in a given potential. ... In principle, the most straightforward way to obtain the solution is to integrate directly the equations of motion for a sufficiently large number of stars with different initial conditions. ... Then space density is given by . ...
