      Metastasis of carcinoma involves migration of tumor cells to distant organs and initiate secondary tumors. Migration requires a complete or partial Epithelial-to-Mesenchymal Transition (EMT), and tumor-initiation requires ...
    • Covariant Time Frequency Representations Through Unitary Equivalence 

      Baraniuk, Richard G. (1996-03-01)
      We propose a straightforward characterization of all quadratic time-frequency representations covariant to an important class of unitary signal transforms (namely, those having two continuous-valued parameters and an ...
    • Critical Uncertainties and Gaps in the Environmental- and Social-Impact Assessment of the Proposed Interoceanic Canal through Nicaragua 

      Huete-Pérez, Jorge A.; Ortega-Hegg, Manuel; Urquhart, Gerald R.; Covich, Alan P.; Vammen, Katherine; Rittmann, Bruce E.; Miranda, Julio C.; Espinoza-Corriols, Sergio; Acevedo, Adolfo; Acosta, María L.; Gómez, Juan P.; Brett, Michael T.; Hanemann, Michael; Härer, Andreas; Incer-Barquero, Jaime; Joyce, Frank J.; Lauer, J. Wesley; Maes, Jean Michel; Tomson, Mason B.; Meyer, Axel; Montenegro-Guillén, Salvador; Whitlow, W. Lindsay; Schnoor, Jerald L.; Alvarez, Pedro J.J. (2016)
      The proposed interoceanic canal will connect the Caribbean Sea with the Pacific Ocean, traversing Lake Nicaragua, the major freshwater reservoir in Central America. If completed, the canal would be the largest infrastruc ...
    • Cross talk between cytokine and hyperthermia-induced pathways: identification of different subsets of NF-κ B-dependent genes regulated by TNFα and heat shock 

      Janus, Patryk; Stokowy, Tomasz; Jaksik, Roman; Szoltysek, Katarzyna; Handschuh, Luiza; Podkowinski, Jan; Widlak, Wieslawa; Kimmel, Marek; Widlak, Piotr (2015)
