Generalized inverses over Banach algebras
LetA be a matrix over a complex commutative unital Banach algebra. We give necessary and sufficient conditions forA to have a generalized inverse. Moreover, if the Banach algebra has a symmetric involution, these...

Group inverses and Drazin inverses over Banach algebras
For a matrix over a complex commutative unital Banach algebra, necessary and sufficient conditions are given for the existence of its group inverse, and more generally, its Drazin inverses. The conditions are ...

Lengthening of the mesentery using the marginal vascular arcade of the right colon as the blood supply to the ileal pouch
PURPOSE: Creation of a safe ileal pouch requires a tension-free anastomosis. The aim of this study was to evaluate a technical procedure that increases the length of the mesentery while preserving the blood su.....

Article
On the optimality in general sense for odd-block search
In his classical article[3], J. Kiefer introduced the Fibonacci search as a direct optimal method. The optimality was proved under the restriction: the total number of tests is given in advance and fixed. To avoi...

Theoretical Studies of Electronic Intersubband Transitions in n-Type Doped Quantum Wells for Infrared Photodetector Applications
A self-consistent (8 × 8)-k · P model based on the Kohn-Sham density-functional formalism is used to calculate the quasi-particle wave functions and energy levels in n-type doped quantum wells. The self-energy...

Article
QTL analysis of rice low temperature germinability
A double haploid population, derived from anther culture of F1 hybrid between a typicalindica and ajaponica (ZYQ8/JX17), has been used to investigate the low temperature germinability (LTG) at 15°C. The low tempe...

Off-diagonal radiative-decay-coupled optical transitions in double quantum wells
When a laser is applied to resonantly excite a multi-level atomic system, there exists quantum interference in the absorption and emission spectra. A proper theory [1] for the radiative decay of excited electrons...

Article
Map-based cloning of the ALK gene, which controls the gelatinization temperature of rice
Gelatinization temperature (GT) is an important parameter for evaluating the cooking and eating quality of rice besides amylose content (AC). The inheritance of the genes affecting GT has been widely studied a...
