Chemical Synthesis And Biological Application Of Sensitive Rna, Alexander T. Apostle

Dissertations, Master's Theses and Master's Reports

In the field of epigenetics - the dynamic collection of chemical modifications that overlay DNA/RNA - there is increasing interest in the potential for therapeutic and research-based utilization of the epitranscriptomics: those epigenetic modifications specific to RNA. Epitranscriptomics can give us a new approach to understanding and treating RNA viruses, like SARS-CoV-2. Given viruses are often found modified by human epitranscriptomic machinery, understanding how these modifications can modulate virulence is of high interest. We have shown that the N1-methyladensoine modification causes RNA synthesis termination in the SARS-CoV-2 replication complex, and thus may explain the differences in symptoms observed in individuals. …

Using A "Moves To Innocence" Approach To Dissect And Debunk The Claim That Critical Race Theory Is Antisemitic, Diane Kemker

Lewis & Clark Law Review

In the United States, law and policy have most frequently reflected dominant white Christian majority interests. Critical Race Theory (CRT) offers powerful tools for understanding our history and situation, including that of American Jews, and how the social positions and interests of American Blacks and Jews, real and perceived, have intersected, sometimes aligning, sometimes diverging, and sometimes conflicting. And yet, among other charges leveled against it, Critical Race Theory is frequently accused of being antisemitic.

Intentionally or not, this charge delegitimizes and discredits CRT, and therefore advances the aims of all who oppose it for any reason, including white supremacists …

Superpowers With Villainous Objectives: How The Executive Branch’S Immigration Enforcement “Powers” Utilize Technology To Violate Noncitizens’ Privacy, Nina-Simone Edwards

Library Scholarship

The United States border, for noncitizens, has a unique quality to it. Each time a noncitizen crosses that border, they are no longer private individuals. They can no longer choose to give up their information–instead, there is a forced exchange: data for entry. Who they are, what they are, and everything that connects them to the world is given up in exchange for a new life in a new land. Once the border is crossed, noncitizens no longer have the privacy that they may have known before. This Note first builds on scholarship theorizing that noncitizens do have a right …

Microfluidic Flowmeter Based On A Liquid Crystal-Filled Nested Capillary, Zhe Wang, Arun Kumar Mallik, Fangfang Wei, Zhuochen Wang, Anuradha Rout, Rayhan Habib Jibon, Qiang Wu, Yuliya Semenova, University College Cork

Articles

Microfluidic flowmeters are a powerful and highly accurate tool, enabling precise monitoring and measurements of flows of gases and fluids in a range of applications. Here we proposed and experimentally demonstrated a whispering gallery modes flowmeter composed of a liquid crystal-filled nested capillary. Whispering gallery modes are excited by a tapered fiber coupled perpendicularly to the nested capillary. The air flowing through the capillary cools it down, which leads to a temperature-induced change of the refractive index of the nematic liquid crystals. This change in turn leads to a spectral shift of the whispering gallery modes resonances, which can be …
