The solution of linear constant-coefficient evolution PDEs with periodic boundary conditions [PDF]
Applicable Analysis, 2012 We implement the new transform method for solving boundary-value problems developed by Fokas for periodic boundary conditions. The approach presented here is neither a replacement for classical methods nor is it necessarily an improvement. However, in addition to establishing that periodic problems can indeed be solved by the new transform method ...

Portopulmonary hypertension practice patterns after liver transplantation
Liver Transplantation, EarlyView., 2022 Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

Multiplicity of periodic solutions in bistable equations [PDF]
, 2006 We study the number of periodic solutions in two first-order non-autonomous differential equations, both of which have been used to describe, among other things, the mean magnetization of an Ising magnet in a time-varying external magnetic field.

Collocation schemes for periodic solutions of neutral delay differential equations [PDF]
, 2005 We introduce two collocation schemes for the computation of periodic solutions of neutral delay differential equations (NDDEs): one based on a direct discretisation of the underlying NDDE, and one based on a discretisation of a related delay differential

Angewandte Chemie, EarlyView.Cyclic adenosine monophosphate (cAMP) is a key cellular second messenger. Adenylyl cyclase converts emissive isomorphic nucleoside triphosphates into fluorescent cAMPs. cthAMP displays unusually high brightness compared to thATP, its precursor, enabling real‐time monitoring of enzymatic reactions.
