, 2015 Matter most commonly exists as a solid, liquid, or gas; these states are known as the three common phases of matter. Solids have a de nite shape and a speci c volume, liquids have a de nite volume but their shape changes depending on the container in

A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes
Quarterly Journal of the Royal Meteorological Society, EarlyView.An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Solving Daniel Bernoulli's St Petersburg Paradox: The Paradox which is not and never was [PDF]
It has been accepted for over 270 years that the expected monetary value (EMV)of the St Petersburg game is infinite. Accepting this leads to a paradox; no reasonable person is prepared to pay the predicted large sum to play the game but will only pay ...

Radius exponent in elastic and rigid arterial models optimized by the least energy principle
Physiological Reports, 2014 It was analyzed in normal physiological arteries whether the least energy principle would suffice to account for the radius exponent x. The mammalian arterial system was modeled as two types, the elastic or the rigid, to which Bernoulli's and Hagen ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT This work investigates three energy‐shaping control approaches to address the trajectory‐tracking problem for specific classes of underactuated mechanical systems. In particular, the notions of contractive systems and dynamic extensions are utilized to solve the trajectory‐tracking problem while addressing implementation issues such as the ...

Recoil Cavity Formation and Collapse for Drop Impact on Sieves
Small Science, EarlyView.A unique secondary cavity arises during droplet impact on a superhydrophobic sieve. Primary cavity collapse induces air suction through the sieve, forming a recoil cavity that collapses to eject droplets. A scaling model explains this process, revealing energy‐driven ejection dynamics and its implications on advanced printing in electronics, biology ...

Small Science, EarlyView.An extrusion‐based technique to engineer a stiffness gradient interphase material that seamlessly bridges soft‐to‐hard interface without strain localization in multimaterial systems is presented. The gradient is obtained by spatial control of the distribution of reinforcing expandable microspheres in polydimethylsiloxane.
