Real-world financial data is often nonlinear, comprises high-frequency multipolynomial components, and is discontinuous (piecewise continuous). Not surprisingly, it is hard to model such data. Classical neural networks are unable to automatically determine the optimum model and appropriate order for financial data approximation. We address this problem by developing neuron-adaptive higher order...

We show that because of the milder GIM suppression, the four-quark dipenguin operator contributes to the short distance piece of the D − D̄ mixing amplitude at the same order of magnitude as the box diagram. In addition, we put an upper bound ∆m D ≤ 5 ×∆mbox D on a long-distance resonant contribution induced by the penguin mixing. The phenomenon of meson mixing has been studied for a long time. ...

We have analytically explored the phenomenon of quantum scattering for unfixed quantum scatterers. We have considered short ranged (δ) interaction between the incident ‘particle’ and the scatterer with no interactions among the scatterers, and the scatterers as (i) particle(s) in a 1-D box, (ii) particle(s) in a 1-D double box, (iii) particle(s) in a 1-D grating, (iv) particle(s) in a 2-D recta...

Determining the middle of the bacteria cell and the proper placement of the septum is essential to the division of the bacterial cell. In E. coli, this process depends on the proteins MinC, MinD, and MinE. Here, the Lattice Boltzmann method (LBM) is used to study the dynamics of the oscillations of the min proteins from pole to pole. This determines the midcell division plane at the cellular le...

Archaeal ribosomal protein L7Ae is a multifunctional RNA-binding protein that recognizes the K-turn motif in ribosomal, box H/ACA, and box C/D sRNAs. The crystal structure of Methanocaldococcus jannaschii L7Ae has been determined to 1.45 A, and L7Ae's amino acid composition, evolutionary conservation, functional characteristics, and structural details have been analyzed. Comparison of the L7Ae ...

some animal models have been used to study alzheimer's disease (ad). ad is an irreversible progressive neurodegenerative disease and the most common cause of dementia. animal studies have shown that there is a relation between decrease in cholinergic functions in the nucleus basalis of meynert (nbm) and loss of learning capability and memory. the aim of this study was to investigate the ef...

The pair-correlation function g(r, t) and its Fourier transform, the structure factor S(q, t), are computed during the gelation process of identical spherical particles using the diffusion-limited cluster-cluster aggregation model in a box. This numerical analysis shows that the time evolution of the characteristic cluster size ξ exhibits a crossover close to the gel time tg which depends on th...
