Analytical expression of transient catalytic current for EC' mechanism using Danckwerts’ expression or Laplace transform

open access: yesResults in Chemistry, 2023
The theoretical analysis of the diffusional electrode for EC' mechanism in the pseudo-first-order catalytic reaction is discussed. The exact, new, closed and compact form of the current profile is derived for this mechanism for all times and with all ...

Constant false alarm rate detection method in polarimetric synthetic aperture radar imagery based on whitening filter under inverse beta distribution

open access: yesThe Journal of Engineering, 2019
The constant false alarm rate (CFAR) detection method based on multi-look polarisation whitening filter (MPWF) has not been obtained in the polarimetric synthetic aperture radar imagery when the texture variable obeys the Inverse Beta distribution.

Simple analytical expression for crosstalk estimation in homogeneous trench-assisted multi-core fibers [PDF]

open access: yes, 2014
An analytical expression for the mode coupling coe cient in homogeneous trench-assisted multi-core fibers is derived, which has a sim- ple relationship with the one in normal step-index structures.

Colored extrinsic fluctuations and stochastic gene expression [PDF]

open access: yes, 2008
Stochasticity is both exploited and controlled by cells. Although the intrinsic stochasticity inherent in biochemistry is relatively well understood, cellular variation, or 'noise', is predominantly generated by interactions of the system of interest ...

Analytical Expression of Average Power-Coupling Coefficients for Estimating Intercore Crosstalk in Multicore Fibers

open access: yesIEEE Photonics Journal, 2012
In order to realize fast and accurate estimation of intercore crosstalk in bent multicore fibers (MCFs), an analytical expression of the average power-coupling coefficient (PCC) based on an exponential autocorrelation function is, for the first time ...

Multidimensional partitioning and bi-partitioning : analysis and application to gene expression datasets [PDF]

open access: yes, 2008
Eigenvectors and, more generally, singular vectors, have proved to be useful tools for data mining and dimension reduction. Spectral clustering and reordering algorithms have been designed and implemented in many disciplines, and they can be motivated ...

An analytical expression for dielectric decrement law

open access: yesAIP Advances, 2020
Dielectric decrement means that the dielectric constant declines with the increase in the ionic concentration of the system, and it is found that, in the dilute solution, the law of the dielectric decrement is linear.

The promoter from SlREO, a highly-expressed, root-specific Solanum lycopersicum gene, directs expression to cortex of mature roots [PDF]

open access: yes, 2008
Root-specific promoters are valuable tools for targeting transgene expression, but many of those already described have limitations to their general applicability.

Expression of an anti-CD33 single-chain antibody by Pichia pastoris [PDF]

open access: yes, 2005
CD33 is a cell surface glycoprotein expressed on cells of myelomonocytic lineage, leukaemic cells, but not haematopoietic stem cells. By virtue of its expression pattern, CD33 has become a popular target for new immunotherapeutic approaches to treat ...
