A Potential Energy Regenerating System Fueled by the Gravitation [PDF]

, 2014
A system of transferring the intangible gravitation to liquid's potential energy was disclosed recently. This system has shown that the intangible gravitation is not just a kind of force; it is also a kind of renewable energy that is harnessable.

The gas streamer G1–2–3 in the Galactic center

Astronomy & Astrophysics
The black hole in the Galactic center, Sgr A*, is prototypical of ultra-low-fed galactic nuclei. The discovery of a handful of gas clumps with masses on the order of a few Earth masses in its immediate vicinity provides a gas reservoir sufficient to ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Gravitational Qubits [PDF]

Universe, 2019
We report on the behavior of two-level quantum systems, or qubits, in the background of rotating and non-rotating metrics and provide a method to derive the related spin currents and motions. The calculations are performed in the external field approximation.

Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

Advanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.

Equilibrium figure of Haumea and possible detection via stellar occultation

Astronomy & Astrophysics
We studied the equilibrium figure of dwarf planet Haumea to determine if the observed shape is compatible with a differentiated hydrostatic body. Three groups of interior models of Haumea were assumed, all with a rocky core and a volatile-rich outer ...

Gauge Theories and Holisms [PDF]

, 2004
Those looking for holism in contemporary physics have focused their attention primarily on quantum entanglement. But some gauge theories arguably also manifest the related phenomenon of nonseparability.
