The regulation of financial derivates: an agent-based model approach
In 2007-08, the world experienced the greatest financial crisis since 1929, which turned – in the following years – in one of the deepest and most prolonged periods of economic stagnation of modern history. While there were multiple conditions that originated the so-called Great Financial Crisis, a …

Syntheses related to the preparation of substituted glycosyl derivates of pyrrolo (3,2-f) quinolines : spectroscopic studies of acetylated glycosylamine derivatives
The synthesis of 25 acetylated glycopyranosylamine derivatives (15 of which are newly reported here) from substituted sugar derivatives and amines is described. Eleven different methods were employed in these syntheses. Of the compounds prepared, 15 are substituted glycosylindoline derivatives. The …

Sequential Enantioselective Iridium-Catalyzed Allylic Alkylation/Cope Rearrangement for the Construction of Acyclic γ-Tertiary or Quaternary Stereocenters
… asymmetric γ-functionalization of carbonyl derivates is challenging because of the issues with ontrolling chemo- (O vs. C), regio- (α vs. γ), and enantioselectivity. In this way, enantioselective transition metal-catalyzed γ-allylic alkylation reactions have attracted increasing attention, …

Preparation of Substituted Enol Derivatives from Terminal Alkynes and Progress Toward the Total Synthesis of Nigricanoside A
… describes the preparation of stereodefined enol derivates of alpha-branched aldehydes from terminal alkynes. Specifically, alkenyl alanes, derived from the methylalumination of alkynes, are shown to be efficiently oxygenated with peroxyzinc species. The resulting metallo-enolate may be trapped …

Tertiary alkylamines as effective directing groups for palladium-catalysed C(sp3)–H activation strategies
… oxidants by a combination of oxygen and alkene derivates, and the reduction of palladium catalyst loadings were explored. Pivotal to the success of these discoveries was the use of mono-protected amino acid ligands. Combined experimental and computational analysis revealed that these readily …

Super-resolution image reconstruction from low-resolution images
… the bicubic interpolation and their first-order derivates and the use of first-order difference equation to extract the features from the low-resolution images are described and shown to improve the method of single image super-resolution using sparse representation. The proposed method has shown …

Novel Directions in Network Steganalysis
… This thesis investigates the use of complexity derivates and a re-embedding technique to answer the two fundamental questions posed above. The experiments presented here show that it is possible to detect and estimate the amount of malicious information accurately in a number of different …

Application of thermodynamic principles in biocatalytic synthesis of novel nucleoside analogues
… unexpected N7-xanthosine and various ribavirin derivates were synthesized and purified in milligram yields. The cytotoxicity in human cell lines was evaluated for selected examples. In conclusion, it is confirmed that thermophilic nucleoside phosphorylases exhibit an impressive substrate scope. …

Clinical translation of nanomaterials for early detection of genetic abnormalities in fetus and retinopathy in neonates and adults
… found that, in comparative studies, the 222-MAMA derivates are more preferred in chelation. However, in either case, once the metal is chelated, there is no conversion of products upon the addition of a more preferred ligand system. Another avenue of target therapy being pursued is the study of …

Application of polyhedrin protein microparticles for in vivo vaccine and biologics delivery: a proof-of-concept study
… conjugation of polyethylene glycol (PEG) and its derivates, are commonly used to increase drug potency. However, recent studies have reported an increase in anti-PEG immunity within the general population due to the widespread use of PEG not only in medicine but also cosmetics and foods, resulting …
