    • Keep up or drown: adjustment of western Pacific coral reefs to sea-level rise in the 21st century 

      van Woesik, Robert; Golbuu, Yimnang; Roff, George (2015-07-22)
      Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for ...

      Van Woesik, Robert; William Cacciapaglia, Christopher (2018-05-08)
      Coral reefs protect islands from tropical storm waves and provide goods and services for millions of islanders worldwide. Yet it is unknown how coral reefs in general, and carbonate production in particular, will respond ...

    • The Kolmogorov equation with time-measurable coefficients 

      Kovats, Jay (2003-07-13)
      Using both probabilistic and classical analytic techniques, we investigate the parabolic Kolmogorov equation $$ L_t v +\frac {\partial v}{\partial t}\equiv \frac 12 a^{ij}(t)v_{x^ix^j} +b^i(t) v_{x^i} -c(t) v+ f(t) ...
    • Lactose variability of Escherichia coli in thermally stressed reactor effluent waters 

      Kasweck, K. L.; Fliermans, Carl B. (1978)
      Lactose-utilizing and nalidixic acid-resistant populations of Escherichia coli, having an optimum growth temperature of 37°C, were placed in modified diffusion chambers. The chambers were submerged in the epilimnion and ...
