Spatio-temporal regimes have undergone a series of significant changes in the past 150 years or so, from the classically modern implication of a standard world time with its grid of 24 time zones in 1884 to the time-space compression ushered in by global capitalism and the more recent ...

In the Discount Criteria list, add records for all the criteria dimensions that you want exposed in the discount matrix. The criteria dimensions that you can add depend on the value selected in the Discount Matrix Type field in Step 2. After all the necessary criteria dimensions are added,...
As previously discussed in the (preliminary, unmerged) pull requests #613 and #615 as well as in issues #612 and (at much greater length) in issue #898, it is desirable for compilations of R extensions to define STRICT_R_HEADERS so that ...
- 《Advances in Mathematics》 被引量: 228发表: 1994年 Matrix subrings having finite global dimension The authors calculate bounds for the global dimensions of certain 'tiled triangular rings' over a ring R. A tiled triangular ring Φ is a subring of M n (R) with (i,j) entry from a ...
We present several complete systems of integrability conditions on the density of the Hamiltonian of a spin chain matrix. The corresponding formulas for R-matrices are also given. The latter are expressed via the local Hamiltonian density in a form similar to spin one half XXX and XXZ models....
vertical scale created an empty two-dimensional framework which was then populated by placing each indicator of a scheme’s EIS (i.e. the smallest discreet unit that can be isolated within the EIS without losing its intent or purpose) into the appropriate place in the two-dimensional matrix. ...
Thus, detecting a senescence-associated cell-cycle arrest requires quantification of multiple factors and features. Secretion Senescent cells secrete a plethora of factors, including pro-inflammatory cytokines and chemokines, growth modulators, angiogenic factors, and matrix metalloproteinases (MMPs), ...
IntroductionA Chevalley-Demazure group scheme G assigns to each commutative ring R agroup G(R). If R is an integral domain with f i eld of fractions k, one can realiseG(R) as the group of R-points of G(k), where G(k) is taken in a given matrixrepresentation (see e.g. [Ab]...
