This paper presents a novel approach to profile-profile comparison. The method compares two input profiles (like those that are generated by PSI-BLAST) and assigns a similarity score to assess their statistical similarity. Our profile-profile comparison tool, which allows for gaps, can be used to detect weak similarities between protein families. It has also been optimized to produce alignments...

Experimentally determined protein tertiary structures are currently increasing in an enormous rate. The growth of the structure database makes structure prediction methods based on known tertiary structures more efficient. Detecting weak homology is crucial to extend applicable area of these methods. For this purpose, a profile or PSSM (position-specific score matrix) derived from multiple alig...

We study the exclusive two-body nonleptonic $B_c\to X_{c\bar{c}}M$ decays, where $X_{c\bar{c}}$ is either a ground(1S) or radially excited (2S 3S) charmonium and $M$ pseudoscalar $(P)$ vector $(V)$ meson. consider here three categories of decays: $B_c \to PP, PV, VP$ decays within framework relativistic independent quark(RIQ) model based on flavor-independent interaction potential in scalar-vec...

Abstract A continuous-state branching process with immigration having mechanism $\Psi$ and $\Phi$ , a CBI $(\Psi,\Phi)$ for short, may have either of two different asymptotic regimes, depending on whether $\int_{0}\frac{\Phi(u)}{|\Psi(u)|}\textrm{d} u<\infty$ or u=\infty$ . When the has limit distribution growth rate dictated by dynamics. $\scriptstyle\int_{0}\tfrac{\Phi(u)}{|\Psi(u)|}\textr...

Using $(448.1 \pm 2.9) \times 10^{6}$ $\psi(3686)$ events collected with the BESIII detector, we perform first search for weak baryonic decay $\psi(3686) \to \Lambda_c^{+} \bar{\Sigma}^- +c.c.$. The analysis procedure is optimized using a blinded method. No significant signal observed, and upper limit on branching fraction ($\mathcal B$) of +c.c.$ set to be $1.4\times 10^{-5}$ at 90\% confidenc...

We extend the recent results of Hussain and Cho [Weak Contractions, Common Fixed Points, and Invariant Approximations, Journal of Inequalities and Applications, vol. 2009, Article ID 390634, 10 pages, 2009] to the Banach pair (T, f) where set of fixed points of f satisfies Dotson’s convexity condition which is more general than the starshapedness.

State transition in photosynthesis is a short-term balancing mechanism of energy distribution between photosystem I (PSI) and photosystem II (PSII). When PSII is preferentially excited (state 2), a pool of mobile light-harvesting complex II (LHCII) antenna proteins is thought to migrate from PSII to PSI, but biochemical evidence for a physical association between LHCII proteins and PSI in state...

In this paper, a concept of monotone generalized contraction in partially ordered metric spaces is introduced and some fixed point and common fixed point theorems for the so-called weak contractions are proved. The concept of weak contraction was introduced by Kada, Suzuki and Takahashi [Math. Japonica, 44 (1996), 381-391], in connection to the concept of w-distance on a metric space. The resul...
