Machine learning (ML) is transforming all areas of science. The complex and time-consuming calculations in molecular simulations are particularly suitable for an ML revolution and have already been profoundly affected by the application of existing ML ...Read More

The lattice summations of the potential energy of importance in the graphite system have been computed by direct summation assuming a Lennard-Jones 6–12 potential between carbon atoms. From these summations, potential energy curves were constructed for interactions between a carbon atom and a graphite monolayer, betwe…
RRATA 1905 events to energetic neutron stars in the stack is large ( 1/10).Also the fiux of energetic neutrons at 90' to
The characteristic energy loss spectra of electrons in the metals Al, C, Sb, Ca, Pb, Na, and Te and compounds of these metals have been measured with an improved measuring technique designed to give more reliable intensity relationships, and it is found that, with the exception of ${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$…
Experimental and theoretical evidence is reviewed to determine if edge emission in CdS is due to exciton recombination or is characteristic of a center. New evidence is presented which shows that edge luminescence may be produced in CdS at low temperatures by stimulating with infrared light, and simultaneous measureme…
The effect of an electric field on the transition between the orthorhombic and tetragonal states in single crystals of BaTi${\mathrm{O}}_{3}$ has been investigated. With zero bias the tetragonal to orthorhombic transition occurs near 5\ifmmode^\circ\else\textdegree\fi{}C and the inverse transition at 11\ifmmode^\circ\…
The Mott series for the Coulomb scattering of electrons by point nuclei have been evaluated numerically with the aid of the UNIVAC computer. Calculations of the series for $F(\ensuremath{\theta})$ and $G(\ensuremath{\theta})$, the scattering cross section, and the polarization asymmetry factor, $S(\ensuremath{\theta})…
The effect of multiple scattering on bremsstrahlung and pair production is considered. The probability of these processes decreases considerably at energies \ensuremath{\gtrsim}${10}^{13}$ ev.The calculations are carried out with the aid of the density matrix. The formulas thus obtained yield the probability of pair p…
