- 2.CAREER: Toward Video2Sim: Turning Real World Videos into Simulations 译 - 美国国家科学基金(NSF) Continuing grant 2019This project develops new technology toward Video2Sim:automatically converting a video into a virtual world,where scenes are reconstructed,actions are re-enacted,and alternative outcomes are simulated by a computer.Such a system does not yet exist due to...
- 3.We plan to continue to develop and assess the efficacy of novel approaches for the treatment of malignant disease based on studies in dogs with spontaneously occurring malignancies. Studies in dogs with malignant lymphoma have shown that some dogs treated...
- 4.The long range objectives of this project are to characterize fundamental properties of the replication-specific mammalian DNA polymerase alpha (pol alpha) and its structural gene and to discern within them unique sites and/or mechanisms which can be expl...
- 5.Mammalian spermatogenesis is a hormone-dependent process regulated mainly by follicle-stimulating hormone (FSH) and testosterone (T). The effects of these hormones on germ cell (Gc) differentiation are believed to be indirect, mediated through the somati...
- 6.Experimental autoimmune myasthenia gravis (EAMG) produced in C57B1/6 mice by immunization with Torpedo acetylcholine receptor has been modulated and attenuated by the in vivo administration of suppressor T cell lines and clones derived from lymph node cel...
- 7.The objectives of this research are to define those immune mechanisms including allergy which have been suggested but not established as important in the pathogenesis of otitis media with effusion (OME). OME is a multifactorial syndrome in which infectio...
- 8.The literatures on behavioral approaches to marital distress and behavioral marital therapy are summarized in terms of implications for understanding and preventing marital distress. Evidence is presented that communication and exchange deficits may be e...
- 9.We have shown previously that the ecf gene of E. coli is intimately associated with the active transport of amino acids and certain simple saccharides. Because of its importance in cellular processes, biochemical and genetic characterization of this ener...
