Essentially Non-Oscillatory and Weighted Essentially Non-Oscillatory Schemes for Hyperbolic Conservation Laws [PDF]

, 1997
In these lecture notes we describe the construction, analysis, and application of ENO (Essentially Non-Oscillatory) and WENO (Weighted Essentially Non-Oscillatory) schemes for hyperbolic conservation laws and related Hamilton- Jacobi equations.

On the integration of L^2-solutions of non-oscillatory solutions to x"+a(t)x'+k^2x=0 [PDF]

International Mathematical Forum, 2014
In this note, sufficient conditions are given to guarantee when all solutions to the linear homogeneous differential equation x"+a(t)x'+k 2 x=0 are both bounded and elements in L 2 (0,∞). Furthermore, when the solutions are non-oscillatory, they are shown to approach 0 as t→∞ and upper bounds are given for ∫ ∞ x(s) 2 ds and ∫ ∞ x'(s) 2 ds.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.
