Porphyrin as Diagnostic and Therapeutic Agent

open access: yesMolecules, 2019
The synthesis and application of porphyrins has seen a huge shift towards research in porphyrin bio-molecular based systems in the past decade. The preferential localization of porphyrins in tumors, as well as their ability to generate reactive singlet ...

Conjugate temperatures

open access: yesJournal of Approximation Theory, 1992
The authors study pairs \((u,v)\) of temperatures on \(\mathbb{R}\times]0,\infty[\) that satisfy the equations \[ D_ x u(x,t)=-iD_ t^{1/2} v(x,t) \qquad\text{and}\qquad iD_ t^{1/2} u(x,t)=D_ x v(x,t), \] which are analogous to the Cauchy-Riemann equations; here \(D_ t^{1/2}\) is a Weyl fractional derivative.

Preconditioning complex symmetric linear systems [PDF]

open access: yes, 2014
A new polynomial preconditioner for symmetric complex linear systems based on Hermitian and skew-Hermitian splitting (HSS) for complex symmetric linear systems is herein presented. It applies to Conjugate Orthogonal Conjugate Gradient (COCG) or Conjugate

Amplifying continuous wave phase conjugate mirror with strontium barium niobate [PDF]

open access: yes, 1982
We report the use of Sr_(1−x) Ba_x Nb_2O_6 as an efficient holographic four‐wave mixing medium. We have used this material in a continuous wave phase conjugate mirror with reflectivity exceeding unity, and in a phase conjugate ...

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 ...

Conjugation of cascades

open access: yesChaos, Solitons & Fractals, 2009
Presented in this work are some results relative to sequences found in the logistic equation bifurcation diagram, which is the unimodal quadratic map prototype. All of the different saddle-node bifurcation cascades, associated to every last appearance p-periodic orbit (p=3,4,5,...), can also be generated from the very Feigenbaum cascade. In this way it

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.

Polysaccharide conjugate vaccine against pneumococcal pneumonia in adults.

open access: yesNew England Journal of Medicine, 2015
BACKGROUND Pneumococcal polysaccharide conjugate vaccines prevent pneumococcal disease in infants, but their efficacy against pneumococcal community-acquired pneumonia in adults 65 years of age or older is unknown. METHODS In a randomized, double-blind,

Passive phase conjugate mirror based on self-induced oscillation in an optical ring cavity [PDF]

open access: yes, 1983
A passive phase conjugate mirror based on four-wave mixing in an optical ring cavity is described. Unlike previously demonstrated passive phase conjugate mirrors it generates only one of its pumping beams by nonlinear optical interactions, the other ...
