Effects Of Uv Exposure On Fecundity, Survival, And Performance Of A Stored Grain Pest, Callosobruchus Maculatus, Colby Christensen, Fielding Mumford, Spencer Brinton, Anna Goates, Md Mirajul Islam

Curiosity

Seed beetles (Callosobruchus maculatus) are a pest of stored leguminous grains that can dramatically decrease yields. Management strategies to control infestations of C. maculatus are important for economic and food security. Radiation exposure is one possible management strategy that has shown promise. In two separate course-based undergraduate research experiences (CUREs), we tested how exposure to UV-C light affects C. maculatus fecundity, survival, and performance. Callosobruchus maculatus individuals were exposed to UV-C at two different life-stages: parent and egg exposure during oviposition and larval exposure during development. Whereas UV exposed two-week old eggs experienced slightly increased mortality, no significant …

Coupled Ferroelectricity And Phonon Chirality, Xiang-Bin Han, Cong Yang, Rui Sun, Xiaotong Zhang, Thuc Mai, Zhengze Xu, Aryan Jouneghaninaseri, Xiaoning Jiang, Rahul Rao, Yi Xia, Multople Additional Authors

Mechanical and Materials Engineering Faculty Publications and Presentations

Recognizing the coupling between ferroelectricity and chirality in optically active ferroelectrics opens a route for manipulating chirality via ferroelectricity under an external electric field, enabling control over chirality-dependent quantum states. Here, we report the experimental demonstration of the coupling between ferroelectricity and phonon chirality in the molecular ferroelectric triglycine sulfate. By electrically switching the crystal chirality, we achieve reversible and device-compatible control of phonon chirality, as revealed by in situ time-resolved magneto-optical Kerr effect measurements. The Kerr rotation reverses with electric-field switching, while phonon chirality vanishes in the paraelectric phase and is tunable in the racemic ferroelectric state. Furthermore, density …

Generalization Of Prolla's Theorem In Approximation, Nadia M. J. Ibrahem, Salwa Salman Abed, Shaimaa S Albundi

Baghdad Science Journal

The principal factor in the proofs of many so-called intersection results and associated best approximation theorems—such as the famed Brouwer fixed-point theorem) is Knaster-Kuratowski-Mazurkiewicz theorem (KKM), which was extended from R^l to Hausdorff vector spaces by Ky Fan. This kind of theory necessitates introducing some form of abstract convex structure on a topological space. In both pure and applied mathematics, the theory of approximation plays a central role. The connection between best approximation and fixed-point theory provides a powerful tool for analyzing the nonlinear maps, the convergence of iterative processes, and the solving of variational …
