The aim of this paper is to study the behaviour of certain sequence of nonlinear Durrmeyer operators $ND_{n}f$ of the form $$(ND_{n}f)(x)=intlimits_{0}^{1}K_{n}left( x,t,fleft( tright) right) dt,,,0leq xleq 1,,,,,,nin mathbb{N}, $$ acting on bounded functions on an interval $left[ 0,1right] ,$ where $% K_{n}left( x,t,uright) $ satisfies some suitable assumptions. Here we estimate the rate...

The organization and function of the photochemical apparatus of Synechococcus 6301 was investigated in cells grown under yellow and red light regimes. Broadband yellow illumination is absorbed preferentially by the phycobilisome (PBS) whereas red light is absorbed primarily by the chlorophyll (Chl) pigment beds. Since PBSs are associated exclusively with photosystem II (PSII) and most of the Ch...

BACKGROUND Although the Pneumonia Severity Index (PSI) has been extensively validated, little is known of the impact of its routine use as an aid to site-of-treatment decisions for patients with pneumonia who present to emergency departments (EDs). METHODS A prospective, observational, controlled cohort study of patients with pneumonia was conducted in 8 EDs that used the PSI (PSI-user EDs) a...

Adaptation of photosynthesis in marine environment has been examined in two strains of the green, picoeukaryote Ostreococcus: OTH95, a surface/high-light strain, and RCC809, a deep-sea/low-light strain. Differences between the two strains include changes in the light-harvesting capacity, which is lower in OTH95, and in the photoprotection capacity, which is enhanced in OTH95. Furthermore, RCC80...

PII: S0962-8924(99)01711-0 [PSI] was originally described in 1965 by Cox as a translation infidelity factor (Fig. 1)1. In [PSI] strains, a weak suppressor tRNA produced detectable nonsense suppression (stop-codon readthrough; see Box 1), whereas in [psi] strains the same tRNA suppressor appeared to be inactive1,2. Later experiments revealed that [PSI] was not required for suppressor tRNA functi...

In a seminal paper, Page found the exact formula for average entanglement entropy pure random state. We consider analogous problem ensemble of fermionic Gaussian states, which plays crucial role in context free Hamiltonians. Using recent results from matrix theory, we show that states subsystem $N_A$ out $N$ degrees freedom is given by $\langle S_A\rangle_\mathrm{G}\!=\!(N\!-\!\tfrac{1}{2})\Psi...

We propose a method by which the intensity of purifying selection on a functional protein-coding gene is estimated by using three aligned homologous sequences: a processed pseudogene (psi), a functional paralog from the same species (g), and a functional ortholog from a different species (o). For each such trio, we calculate the numbers of nucleotide substitutions along the branches leading to ...
