Analyzing The Impact Of Negative Sampling On Fact-Prediction Algorithms, Iti Bansal

Theses

Knowledge graphs are useful for many applications like product recommendations and web search query engines. However, knowledge graphs are marked by incompleteness. Fact-prediction algorithms aim to expand knowledge graphs by predicting missing facts. Fact-prediction algorithms train models using positive facts present and creating negative facts not present in the knowledge graph at hand. Negative facts are obtained by corrupting information in the positive facts present in the knowledge graph at hand. Although it is generally assumed that negative facts drive the accuracy of fact-prediction algorithms, this concept has not been thoroughly examined yet. In this work, we investigate whether negative …

One-Pot O-Alkylation And C-C Cross-Coupling Reactions Involving Stabilized Phosphoranes, Areej Hashim Mohamed

Theses

This thesis is concerned with the one-pot reactions that are considered to be beneficial to preserve resources, save time, and are deemed a green chemistry strategy. To plan such one-pot reactions, it is important to combine two or more reactions that are compatible with each other and can be run under the same reaction conditions. In this work, possibilities of a combination of Wittig-olefination and Suzuki C-C-cross coupling reactions are explored further. Reaction sequences involve the combination of a Suzuki-reaction / Wittig olefination, a Suzuki reaction / Wittig olefination/hydrolysis, and a Suzuki-reaction / double Wittig olefination. In all cases, stabilized …

Development Of Supramolecular Multicomponent Chromophores Towards Photoluminescence Switches, Rukayat Shola Bojesomo

Theses

A new fluorescent dye (4PBZC) comprises of coumarin (C), piperazine (P), and benzimidazole (BZ) was designed, prepared, and complexed to cucurbit[7]uril (CB7) to detect carnosol (CAR), an anti-breast cancer drug, in sub-nanomolar concentrations utilizing the supramolecular indicator displacement assay (IDA) strategy, the CB7-assisted pK_a shift and the CB7-retarded photoinduced electron transfer (PET) process. The host−guest complexation was confirmed by UV−visible absorption, fluorescence, and proton NMR spectroscopy, which confirm binding to 4PBZC via the BZ moiety. Also, CB7 preferentially binds the indicator dye via the protonated BZ residue compared to the neutral BZ one, demonstrated by a higher binding …

Green Synthesis, Characterization, Antioxidant And Anticancer Activities Of Silver Nanoparticle Using Moringa Peregrina Leaf Extract, Khaled Saeed Al Baloushi

Theses

The sustainable green synthesis process for the development of environment-friendly, toxicant-free and biocompatible nanoparticles establishes important aspects in nanotechnology research.

New Approaches For Isolation And Characterization Of Extracellular Vesicles, Mehdi Dehghani

Theses

Extracellular vesicles (EVs) are membrane vesicles secreted by cells and distributed widely in all biofluids. Extracellular vesicles can modulate the biological activities of the recipient cells. Due to their role in intercellular communication, they are receiving attention for therapeutic and diagnostic applications. The first step to better understand EVs and to utilize them as therapeutic and diagnostic tools is to purify them from a variety of biofluids. Membranes have been extensively used for purification of different biological species from biological fluids. As the first aim, a novel microfluidic system, termed as tangential flow for analyte capture (TFAC) was developed to …

The Effect Of Phytoplankton Properties On The Ingestion Of Marine Snow By Calanus Pacificus, Grace Cawley

Theses

The aggregation of phytoplankton into marine snow provides a mechanism by which smaller particles can coagulate to form larger particles, which can be consumed at various depths or readily transported to the deep ocean and sequestered from the atmosphere on time scales of a thousand years or more. Zooplankton interacting with these large carbon-rich aggregates can obtain nutrition in environments where the phytoplankton size spectrum is small and not directly available, enhancing the possibility of obtaining adequate nutrition in environments dominated by small cells. In addition, interactions between zooplankton and marine snow can result in fragmentation, thus affecting the particle …

The Economic Impacts Of Nuclear Power Plant Closures On Rural Communities, Christina Maher

Theses

The 2015 announcement to close Indian Point Energy Center (IPEC) in Buchanan, NY caused a shockwave of concerns for the local community. As a rural community, Buchanan, NY relies on major employers to provide long-lasting careers with steady incomes and steady tax revenue for the community (Mitchell, 2019). A major employer is a business that produces more goods and services than can be utilized by the local economy, and therefore it exports a significant portion of its goods and employs five hundred workers or more (Montrose EDC, 2019). The type of industries that are major employers includes manufacturing, energy plants, …
