Regularity, Uniqueness And The Relative Size Of Small And Large Scales In Sqg Flows, Z. Akridge, Z. Bradshaw

Mathematical Sciences Faculty Publications and Presentations

The problems of regularity and uniqueness are open for the supercritically dissipative surface quasi-geostrophic equations in certain classes. In this note we examine the extent to which small or large scales are necessarily active both for the temperature in a hypothetical blow-up scenario and for the error in hypothetical non-uniqueness scenarios, the latter understood within the class of Marchand's solutions. This extends prior work for the 3D Navier-Stokes equations. The extension is complicated by the fact that mild solution techniques are unavailable for supercritical SQG. This forces us to develop a new approach using energy methods and Littlewood-Paley theory.

Metabolic And Physiological Regulation In C. Elegans: Insights Into Sperm Activation And Peroxisome-Mediated Longevity, Yash Flora

LSU Doctoral Dissertations

Organelle dynamics lie at the heart of cellular signaling and metabolic regulation, orchestrating physiological processes such as reproduction and aging across the lifespan. In this dissertation, I investigate how organelle-based signaling coordinates sperm activation and modulates organismal aging in the nematode Caenorhabditis elegans. I identify SPIN-4, a previously uncharacterized Spinster family transporter, as a key regulator of spermiogenesis. SPIN-4 is strongly expressed in developing sperm, localizes to the plasma membrane, and promotes sperm activation by facilitating the export of sphingosine-1-phosphate (S1P). Loss of spin-4 results in defective pseudopod formation, reduced motility, and compromised fertility, phenotypes that can be rescued …

Friction Points Between The Eu Data Act And Wto Law, Pedro R. Borges De Carvalho

Indian Journal of International Economic Law

It has been noted that many of the provisions of the EU Data Act are protectionist in character, seemingly designed to guard data as a national resource to be explored by EU actors first and foremost, and not to be exported, to the detriment of third-country companies. To international trade treaty partners, most notably the United States, it may seem as though the EU’s policy of digital sovereignty, in its current contours, risks violating WTO Law, which is premised on ideals of global free trade and comparative advantage. This essay analyses the most problematic provision of the Data Act in …
