Exact solution of a nonlinear model of four-wave mixing and phase conjugation [PDF]

open access: yes, 1982
An exact solution of a nonlinear model of holographic four-wave mixing is derived. An expression for the reflectivity of a phase-conjugate mirror with depleted pumps is presented.

Express ELISA for detection of mortalin

open access: yesBioTechniques, 2019
Mortalin is a widely studied stress chaperone that plays a significant role in diseases such as cancer, diabetes mellitus, liver cirrhosis, neurodegeneration and generalized aging. Based on these, the level of mortalin expression has been predicted to be

Instantaneous complex conjugate resolved spectral domain and swept-source OCT using 3x3 fiber couplers [PDF]

open access: yes, 2005
We report that the complex conjugate artifact in Fourier domain optical coherence tomography approaches (including spectral domain and swept source OCT) may be resolved by the use of novel interferometer designs based on 3x3 and higher order fiber ...

Retrovirus molecular conjugates [PDF]

open access: yesCellular and Molecular Life Sciences (CMLS), 2001
Retrovirus-derived vectors are currently the preferred vectors used for human gene therapy protocols. Serious safety concerns persist, however, which are specifically related to the formation of a replication-competent virus, and no synthesis method currently employed precludes its formation with certainty.

Vi polysaccharide and conjugated vaccines afford similar early, IgM or IgG-independent control of infection but boosting with conjugated Vi vaccines sustains the efficacy of immune responses

open access: yesFrontiers in Immunology, 2023
IntroductionVaccination with Vi capsular polysaccharide (Vi-PS) or protein-Vi typhoid conjugate vaccine (TCV) can protect adults against Salmonella Typhi infections.

A Three-Term Conjugate Gradient Method with Sufficient Descent Property for Unconstrained Optimization [PDF]

open access: yes, 2011
Conjugate gradient methods are widely used for solving large-scale unconstrained optimization problems, because they do not need the storage of matrices.

A Scaled Conjugate Gradient Algorithm for Fast Supervised Learning

open access: yes, 1990
A supervised learning algorithm (Scaled Conjugate Gradient, SCG) with superlinear convergence rate is introduced. The algorithm is based upon a class of optimization techniques well known in numerical analysis as the Conjugate Gradient Methods.

Synthesis and in vitro Evaluation of Levothyroxine- Targeted Paclitaxel-Dextran Conjugate for Drug Delivery to Cancer Cells [PDF]

open access: yesTrends in Pharmaceutical Sciences, 2023
Taxanes are a class of potent anticancer agents used in different cancers. Their low water solubility is the major challenge in formulation development that leads to the use of surfactants and organic solvents which causes severe hypersensitivity ...

Calculation of the Stability Index in Parameter-Dependent Calculus of Variations Problems: Buckling of a Twisted Elastic Strut [PDF]

open access: yes, 2002
We consider the problem of minimizing the energy of an inextensible elastic strut with length 1 subject to an imposed twist angle and force. In a standard calculus of variations approach, one first locates equilibria by solving the Euler--Lagrange ODE ...

Semi-self-pumped phase-conjugate mirrors [PDF]

open access: yes, 1987
We describe semi-self-pumped photorefractive phase-conjugate mirrors based on the unidirectional ring resonator and the double phase-conjugate mirror.
