Cyclic and Long-term Variation of Sunspot Magnetic Fields
, 2013 Measurements from the Mount Wilson Observatory (MWO) are used to study the long-term variations of sunspot field strengths from 1920 to 1958. Following a modified approach similar to that in Pevtsov et al.

Optimization of ceramic strength using elastic gradients [PDF]
Acta Materialia, 2009 We present a new concept for strengthening ceamics by utilizing a graded structure with a low elastic modulus at both top and bottom surfaces sandwiching a high-modulus interior. Closed-form equations have been developed for stress analysis of simply supported graded sandwich beams subject to transverse center loads.

Nonhomogeneity Analysis Using Borrowed Strength [PDF]
Journal of the American Statistical Association, 1996 Abstract This article develops a “borrowed strength” methodology for estimating local probability densities in a random field. Under a piecewise stationarity condition similarities between the densities in different regions of the field can be exploited by estimating a global mixture density and imposing the parameter-space support of this borrowed ...

Statistics of electromagnetic transitions as a signature of chaos in many-electron atoms
, 1998 Using a configuration interaction approach we study statistics of the dipole matrix elements (E1 amplitudes) between the 14 lower odd states with J=4 and 21st to 100th even states with J=4 in the Ce atom (1120 lines). We show that the distribution of the

Resonant tunneling controlled by laser and constant electric fields
, 2011 We develop the concept of scattering matrix and we use it to perform stable numerical calculations of resonant tunneling of electrons through a multiple potential barrier in a semiconductor heterostructure.
