Technique Makes Nmr Nanomaterials Exotic Matter Research
2018/1/10
Nuclear magnetic resonance (NMR) is a powerful scientific tool used in medical imaging and in probing the chemical structure of molecules and compounds. New research from Brown University shows a tech...
Tem-fast: a useful tool for hydro-geologists and environmental engineers
electromagnetic sounding hydrogeology environment resistivity measurements
2015/9/29
Time Domain Electromagnetic (TDEM) methods have proven to be efficacious in many studies involving environmental and engineering problems, producing better results than the traditional galvanic techni...
Classical Scaling Symmetry Implies Useful Nonconservation Laws
Nonconservation Laws symmetry dynamically
2010/4/2
Scaling symmetries of the Euler-Lagrange equations are generally not variational symmetries of the action and do not lead to conservation laws. Nevertheless, by an extension of Noether's theorem, scal...
A useful guide for gravitational wave observers to test modified gravity models
gravitational wave modified gravity models
2010/3/17
We present an extension of a previously suggested test of all modified theories of gravity that would reproduce MOND at low accelerations. In a class of models, called "dark matter emulators", gravita...
All entangled states are useful for channel discrimination
entangled states useful channel discrimination
2010/4/8
We prove that every entangled state is useful as a resource for the problem of minimum-error channel discrimination. More specifically, given a single copy of an arbitrary bipartite entangled state, i...
