Deep understanding of molecular biology has allowed emergence of new technologies like DNA decryption. On the other hand, advancements of molecular biology have made manipulation of genetic systems simpler than ever; this promises extraordinary progress in biological, medical and biotechnological applications. This is not an unrealistic goal since genes which are regulated by gene regulatory ...
BACKGROUND Little is known about native and non-native rodent species interactions in complex tropical agroecosystems. We hypothesised that the native non-pest rodent Rattus everetti may be competitively dominant over the invasive pest rodent Rattus tanezumi within agroforests. We tested this experimentally by using pulse removal for three consecutive months to reduce populations of R. everetti...
Cellular functions are mediated through complex systems of macromolecules and metabolites linked through biochemical and physical interactions, represented in interactome models as 'nodes' and 'edges', respectively. Better understanding of genotype-to-phenotype relationships in human disease will require modeling of how disease-causing mutations affect systems or interactome properties. Here we...
Relativistic many-body calculations of energy levels, hyperfine constants, electric-dipole matrix elements and static polarizabilities for alkali-metal atoms. Abstract Removal energies and hyperfine constants of the lowest four ns, np 1/2 and np 3/2 states in Na, K, Rb and Cs are calculated; removal energies of the n=7–10 states and hyperfine constants of the n=7 and 8 states in Fr are also cal...
an efficient method was employed for the ash and pyrite sulphur removal from bitumen using column flotation process. the bitumen samples containing 9.6% sulphur (6.81% in the pyrite sulphur form) and 26.4% ash were successfully showed up to 75.20% of pyrite sulphur (e.g.; 51.66% of total sulphur) and 70.81% of ash removal. the box-behnken design (bbd) was employed to design the experiments, to ...

the dynamical behaviour of the forced escape oscillator, which depends on the parameter values we considered, have been studied numerically using the techniques of phase portraits and poincar'{e} sections. also, we employed perturbation methods such as lindstedt's method to obtain the frequency-amplitude relation of escape oscillator.
The accurate prediction of the band gaps halide perovskites within density functional theory is known to be challenging. recently developed Wannier-localized optimally tuned screened range-separated hybrid was shown highly for fundamental standard semiconductors and insulators. This achieved by selecting parameters satisfy an ansatz that generalizes ionization potential theorem removal charge f...
This work presents first quantitative results of a method for automatic liver segmentation from CT data. It is based on a 3D deformable model approach using a-priori statistical information about the shape of the liver gained from a training set. The model is adapted to the data in an iterative process by analysis of the grey value profiles along its surface normals after nonlinear diffusion fi...
New studies in neuromuscular control have indicated that the strength of muscle contraction isn’t the only important factor in a task. But the speed at which a muscle responds, preparation of muscle and synergistic pattern at which a group of muscles recruit to a task or respond to a condition are much more important in constant joint stabilization and potential injury prevention. The purpo...
