Editors’ note: The following chapter has been the subject of considerable controversy during the review process. Although one reviewer found the claim that gravitational waves could be detected or generated by the method proposed in this paper to be reasonable, the other reviewers found this claim to be highly questionable. In particular, the reviewers and editors believe that some statements i...

Modeling Chemical EOR Processes: Some Illustrations from Lab to Reservoir Scale — Chemical flooding, SP (Surfactant Polymer) or ASP (Alkali-Surfactant-Polymer), are of increasing interest due to the need to increase oil production. Design of chemical processes is very project specific and requires case by case studies including various steps among which reservoir data analysis, chemical formula...

Pairs of Planck-mass–scale drops of superfluid helium coated by electrons (i.e., “Millikan oil drops”), when levitated in the presence of strong magnetic fields and at low temperatures, can be efficient quantum transducers between electromagnetic (EM) and gravitational (GR) radiation. A Hertz-like experiment, in which EM waves are converted at the source into GR waves, and then back-converted a...

functionals were discovered and used by volterra over a century ago in his study of the motions of viscous elastic materials and electromagnetic fields. the need to precisely account for the qualitative effects of the cohesion and shape of the domains of these functionals was the major impetus to the development of the branch of mathematics known as topology, and today large numbers of mathemat...

A spectrometer incorporating a high transition temperature dc superconducting quantum interference device ~SQUID! is used to obtain nuclear magnetic resonance signals from protons in mineral oil at room temperature in fields up to 3 mT. The spatial separation between the SQUID magnetometer at 77 K and the sample at room temperature is less than 1 mm. At 2 mT, the signal is easily resolved in a ...

We present a microlens array consisting of multiple liquid-based tunable-focus microlenses omnidirectionally fabricated on a hemisphere, resulting in large field of view. Polymer bridge structure is formed between microlenses to reduce the stress and deformation in each lens structure. Each microlens in the array is formed via a water-oil interface at its lens aperture. Photopatterned thermo-re...
