Creating, Destroying And Preserving Coherence With Quantum Channels, Masaya Takahashi

Dissertations

Quantum coherence is a fundamental property of quantum systems that can be studied within the framework of a quantum resource theory. In chapter 2, we consider how much coherence can be either generated or destroyed on a bipartite system when the action is restricted to local unitary operations. For pure states, we find that the relative entropy of entanglement and the robustness of entanglement provide tight lower bounds on the amount of coherence that can be destroyed by local unitaries, as measured by the relative entropy and L1 measures of coherence, respectively. We then study the amount of bipartite pure …

Roles Of Phospholipase Dε In Arabidopsis And Soybean Response To Nitrogen Deficiency, Shuaibing Yao

Dissertations

Phospholipase D (PLD) hydrolyzes phospholipids to produce phosphatidic acid (PA) and plays important roles in plant growth, development, and stress response. Of 12 PLDs in Arabidopsis, PLDε is involved in nitrogen response in Arabidopsis and canola, but the mechanism remained elusive. This study was undertaken to investigate how PLDε mediates plant response to nitrogen availability. Nitrogen deficiency induces an increase in PLDε transcript and protein levels and an increased association with intracellular membranes. PLDε interacts with autophagy-related protein 8e (ATG8e), and two of the four predicted ATG8-interacting motifs in PLDε are required for PLDε-ATG8e interactions. PLDε hydrolyzes phosphatidylethanolamine (PE) conjugated …

Bisexual+ Women Of Color And Microaffirmations, Zori Paul

Dissertations

In the last decade, there has been an interest in exploring affirming identity factors for bisexual+ (bisexual, pansexual, queer, fluid, etc.) individuals that would promote positive mental wellbeing.

When "First, Do No Harm" Fails: A Restorative Justice Approach To Workgroup Harms In Healthcare, Pedro L. Flores

Dissertations

In healthcare, workgroup mistreatment is a pervasive problem that begins during medical education (medical and nursing school) and becomes embedded in the “hidden curriculum of professionalism,” which dissuades and even punishes learners for talking about abuse they witness. Furthermore, the mistreatment of healthcare providers (HCPs) pervades all disciplines in the healthcare delivery chain due to a combination of cultural factors, systemic pressures, dysfunctional hierarchies, and leadership’s tolerance of intimidating and disruptive behaviors. Not surprisingly, 18% of U.S. HCPs have left the medical field since the start of the COVID-19 pandemic, and burnout, stress, anxiety, and increased workloads have been identified …

Factors Associated With Household Contacts' Tuberculosis Testing And Evaluation, Elvy G. Barroso
