Momentum transfer and foam production via breaking waves in hurricane conditions
Generated under hurricane conditions, a slip layer composed of foam, bubble emulsion, and spray determines the behavior of the surface drag with wind speed. This study enables us to estimate foam's contribution to this behavior. A logarithmic parametrization of surface drag is introduced, wherein the effective roughness length of the underlying surface is decomposed into three fractional roughness lengths. These correspond to the foam-free area (as determined by laboratory data, which includes …

The wife and I decided to shopping for a new mattress today and we ended buying this Nectar mattress(king size) to replace our 8 year old mattress.
This is a memory foam mattress, which we've never owned before, so definitely going to be interesting to see how it is once it arrives, which is due to happen April 9th - 12th.

Partial absence of cosine problem in 3d Lorentzian spin foams
We study the semi-classical limit of the recently proposed coherent spin foam model for (2+1) Lorentzian quantum gravity. Specifically, we analyze the gluing equations derived from the stationary phase approximation of the vertex amplitude. Typically these exhibit two solutions yielding a cosine of the Regge action. However, by inspection of the algebraic equations as well as their geometrical realization, we show in this note that the behavior is more nuanced: when all triangles are either spa…

Trying another GF cake; this one a simple almond cake. Weighing the flours is easy. Clarifying the butter is not.
I got distracted, so instead of clarified butter it was browned butter minus the foam.
Includes maraschino liqueur, orange zest, and a crusty turbinado sugar top that makes all the slices look sloppy. But whatever, it tastes great.

Starting June 1, 2024, Washington will ban the sale and distribution of foam coolers, takeout containers, cups, plates and other food and drink items made from expanded polystyrene (Styrofoam) due to environmental and recycling concerns.
It's the right choice, but will chicken teriyaki hit the same out of compressed paper takeout containers?

Dark energy from topology change induced by microscopic Gauss-Bonnet wormholes
It is known that the appearance of microscopic objects with distinct topologies and different Euler characteristics, such as instatons and wormholes, at the spacetime-foam level in Euclidean quantum gravity approaches, leads to spacetime topology changes. Such changes, in principle, may affect the field equations that arise through the semiclassical variation procedure of gravitational actions. Although in the case of Einstein-Hilbert action the presence of microscopic wormholes does not lead t…

It's now been about 2 weeks or so since the wife and I got our first memory foam mattress, which we decided on a Nectar brand.
During these two weeks or so, I've been sleeping considerably better. I sleep a bit later than I was there for a while as I now wake up around 6am instead of between 4am - 5am.
I also don't wake up with a sore back, headaches or feeling like I want to immediately go lay down on the couch and take a nap. (cont...)
