The inhibitory effects of Chinese leek (Allium tuberosum) on Fusarium oxysporum f. sp. cubense (Foc) and on Fusarium wilt incidence were studied in order to identify a potential efficient way to control the disease. Adopting the rotation system of Chinese leek-banana reduced the Fusarium wilt incidence and disease severity index by 88–97 % and 91–96 %,(More)
A regularized color clustering algorithm is proposed to solve the color clustering problem in medical image database. By incorporating both measures of cluster separability and cluster compactness, regularized color clustering allows the automatic extraction of significant color groups with varying populations. Experimental results in different color spaces(More)
Experience in the development and maintenance of software leads to the design of methodologies for different phases of the software engineering process. Such methodologies attempt to usefully support the programmer's thought process for re-creating only good, standard patterns of programming without limiting creativity. However methodologies, as they are(More)
In this study, the three-dimensional (3-D) trajectory (TDT) method for deoxyribo-nucleic acid (DNA) sequence visualization and comparison is proposed. The global view of a DNA sequence in any sizes can be easily graphically represented by a TDT and examined for sequence characteristics. Studies of the TDTs of known DNA sequences and computer-generated(More)
The surface states of 3D topological insulators (TIs) exhibit a helical spin texture with spin locked at right angles with momentum. The chirality of this spin texture is expected to invert crossing the Dirac point, a property that has been experimentally observed by optical probes. Here, we directly determine the chirality below the Dirac point by(More)
Three-dimensional topological insulators (TIs) exhibit time-reversal symmetry protected, linearly dispersing Dirac surface states with spin-momentum locking. Band bending at the TI surface may also lead to coexisting trivial two-dimensional electron gas (2DEG) states with parabolic energy dispersion. A bias current is expected to generate spin polarization(More)
