Mass-Independent Isotope Effects
The Journal of Physical Chemistry B, 2013Three fundamental properties of atomic nuclei-mass, spin (and related magnetic moment), and volume-are the source of isotope effects. The mostly deserved and popular, with almost hundred-year history, is the mass-dependent isotope effect. The first mass-independent isotope effect which chemically discriminates isotopes by their nuclear spins and ...

From Effective Mass to Negative Mass
1995In order to minimize the difficulties students encounter during their familiarization with the concept of effective mass in solid state physics theory, a simple example from another field of physics could be introduced. This is also of interest in a framework of general physics.

Abstract The mere neglect of a mass effect is quite suspect and often not correct. In the previous chapters, we developed a general formalism for calculating multiple bremsstrahlung in gauge theories at high energies. By considering the limit of vanishing fermion masses, we were able to obtain simple expressions for the various ...

March 11, 2011 is a day I will never forget. I had just arrived home to my Tokyo apartment and was searching the house for some documents I needed for an urgent errand. As I leafed through stacks of papers on my desk, I began feeling the all-too-common motion of an earthquake.

Changes in lean body mass with glucagon‐like peptide‐1‐based therapies and mitigation strategies
Diabetes, obesity and metabolismWeight loss induced by glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) and dual glucagon‐like peptide‐1 receptor (GLP‐1R)/glucose‐dependent insulinotropic polypeptide receptor agonists is coming closer to the magnitudes achieved with surgery ...

ACM SIGGRAPH 2010 Computer Animation Festival, 2010
Like many a brilliant mastermind, the Illusive Man sits quietly orchestrating the fate of the universe while soldiers fight the battle. This character-driven piece showcases the gritty combat skills of the game's assassins and savages as they fight against the galactic invasion of an alien race bent on destroying humanity.

Physical Review B, 1984
A new type of superlattice which is constructed with a periodic modulation of effective mass is proposed. Candidate materials for this superlattice are presented. The analysis shows that there exist continuously electronic subbands in real space.

The effective-mass theory or approximation (EMA), also termed the envelope function approximation, is widely used for calculating the electronic properties of carriers in potentials in an otherwise periodic crystal. The strength of the method is that the complexities of the periodic potential are hidden in the effective-mass tensor m∗ ij .
