• A comparison of some numerical conformal mapping methods for simply and multiply connected domains 

  Badreddine, Mohamed; DeLillo, Thomas K.; Sahraei, Saman (American Institute of Mathematical Sciences, 2019-01)

  This paper compares some methods for computing conformal maps from simply and multiply connected domains bounded by circles to target domains bounded by smooth curves and curves with corners. We discuss the use of explicit ...

• Optically thin core accretion: how planets get their gas in nearly gas-free discs 

  Lee, Eve J.; Chiang, Eugene; Ferguson, Jason W. (Oxford University Press, 2018-05-11)

  Models of core accretion assume that in the radiative zones of accreting gas envelopes, radiation diffuses. But super-Earths/sub-Neptunes (1-4 R-circle plus, 2-20M(circle plus)) point to formation conditions that are ...

• Programming quantum annealing computers using machine learning 

  Behrman, Elizabeth C.; Steck, James E. (IEEE, 2017)

  Lorenzo, Edgardo; Malla, Ganesh B.; Mukerjee, Hari (Taylor & Francis, 2018-03-02)

  The mean residual life of a non negative random variable X with a finite mean is defined by M(t) = E[X - t|X > t] for t 0. One model of aging is the decreasing mean residual life (DMRL): M is decreasing (non increasing) ...

  Crenshaw, Julie N.; Echart, Alexandra K.; Lancaster, Kirk E. (Pacific Journal of Mathematics, 2018-02)

  The principal existence theorem (i.e., Theorem 1) of "Existence and behavior of the radial limits of a bounded capillary surface at a corner" (Pacific J. Math. 176:1 (1996), 165-194) is extended to the case of a contact ...
