On the Complexity of the Bilevel Shortest Path Problem

open access: yesNetworks, EarlyView.
ABSTRACT We introduce a new bilevel version of the classic shortest path problem and completely characterize its computational complexity with respect to several problem variants. In our problem, the leader and the follower each control a subset of the edges of a graph and together aim at building a path between two given vertices, while each of the ...

Autorotating dispersal units of Getonia floribunda Roxb. (Combretaceae): morphology, aerodynamics and geometrical significance

open access: yesNordic Journal of Botany, EarlyView.
Dispersal units that continuously rotate while falling purely due to aerodynamic forces are called autorotating dispersal units. Single‐ to multi‐winged forms of autorotating dispersal units occur in nature. The dispersal unit of Getonia floribunda Roxb.

Phillygenin Improves the Focal Adhesion Kinase/Glycogen Synthase Kinase 3β/β‐Catenin Axis to Promote Mesenchymal Stem Cell Osteogenic Differentiation

open access: yesPhytotherapy Research, EarlyView.
Schematic diagram of Phillygenin improves the focal adhesion kinase/glycogen synthase kinase 3β/β‐catenin axis to promote mesenchymal stem cell osteogenic differentiation. ABSTRACT Forsythiae Fructus, a traditional herb known for its anti‐inflammatory and antioxidant properties, has demonstrated inconclusive effects on bone metabolism in prior studies.
