Organocatalytic conjugate addition reactions
… to be an efficient catalyst for base catalyzed conjugate addition between 2(3H)-furanones and maleimides. Aromatic furanones substrates proved to be better than alkyl furanones, giving higher yields and better ees. The best result is a decent ee of 70%. There is still room for improvements in …

Copper-catalyzed conjugate reduction
… enantioselective catalyst for the asymmetric conjugate reduction of a,- unsaturated cyclic ketones was generated upon combination of catalytic amounts of CuCl, NaOt-Bu, and a chiral bis-phosphine with poly(methylhydrosiloxane) (PMHS) as the stoichiometric reductant. In this process, chiral …

Polynomial Preconditioning for Conjugate Gradient Methods
… When A is hermitian positive definite (hpd), the conjugate gradient method of Hestenes and Stiefel is popular. When A is hermitian indefinite (hid), the conjugate residual method may be used. If A is ill-conditioned, these methods may converge slowly, in which case a preconditioner is needed. In …

Conjugate Reinforcement: The Effects of Stimulus Clarity
… are schedules of covariation, specifically conjugate reinforcement. While less studied, conjugate reinforcement schedules have been used predominately in basic studies examining a variety of phenomena. Recent research (MacAleese et al., 2015) is beginning to examine the schedule, and its …

Conjugate operator on variable harmonic Bergman space
… the imaginary part, which is called the harmonic conjugate of the real part? Treating the relationship as an operation, the question becomes how well behaved is the harmonic conjugate operator? In this paper, by modifying some classical methods in constant exponent Hardy and Bergman spaces and …

Conjugate generalized linear mixed models with applications
This thesis focuses on the development of conjugate generalized linear mixed models (CGLMMs), which is a computationally efficient modelling framework for longitudinal and multilevel data where the likelihood can be expressed in closed-form. We focus on the scenario where the random effects are …

Novel Conjugate Additions and Cyclizations on Multiyne Systems
… with electron-deficient 1,3-diynes that are conjugated with an electron-withdrawing group such as ketone, ester, or imide functionalities to synthesize unique heterocyclic molecules like THPs, furans and pyrroles. Alcohols, amines, and thiols show excellent reactivity for the initial …

Novel sustained release formulation of leveodopa-dendrimer conjugate
… incorporated in a nanoparticle. To prepare the conjugate levodopa (1mg/ml) was added to dendrimer solution (1mg/ml) at alkaline pH. They were allowed to react for 45 minutes with constant stirring and then lyophilized. The conjugate between levodopa and PAMAM dendrimer was characterized using …

Enantioselective Conjugate Additions to a Hindered Cyclohexenone System
… Birch-Cope products to carbon nucleophile conjugate additions to enantioselectively generate vicinal quaternary-tertiary stereocenters. Intermolecular conjugate additions were studied extensively but were unfortunately limited in scope. It is hypothesized that steric congestion around the …

Conjugate-lateral eye movement behavior in later childhood
… research in brain functioning has indicated that conjugate-lateral eye movement direction (the direction in which a person looks while thinking) can be a sensitive indicator of which cerebral hemisphere is initially activated. The central purpose of this investigation was to analyze the effects of …

Spatiotemporal dynamics of a photorefractive phase-conjugate resonator
… dynamics of a photorefractive phase-conjugate resonator (PPCR) is studied both experimentally and analytically. The resonator is a confocal cavity bounded by a dielectric mirror and a phase-conjugate mirror in a four wave mixing geometry. The effect of the Bragg mismatch, which is …

Bispecific Ligand Conjugate Immunotherapy of Choroid Plexus Brain Tumors
… into the application of bispecific ligand conjugates to the treatment of human cancers. Application of this design includes all tumors that express folate receptors, but additional ligands may be used to target other tumor varieties.

Physicochemical studies of a novel adjuvant and conjugate vaccines
… DTP-HBV-Hib vaccine. The Hib vaccine is a glycoconjugate in which Haemophilus influenzae type b capsular polysaccharide (polyribosylribitolphosphate or PRP) is conjugated to a carrier protein. The conjugate is immunogenic in infants who have a higher risk of infection while the polysaccharide …

Strategies for combinatorial development of siRNA conjugate delivery systems
… lipid nanoparticles (LNPs) and small molecule conjugates. LNPs are among the most potent and diverse nonviral delivery systems, and they have enjoyed continued improvement in efficacy as new generations of lipids have been explored. This steady progress in lipid performance has relied heavily …
