Model-independent study of light-cone current commutators
An attempt is made to extract information on the nature of light-cone current commutators (LCC) in a model-independent manner. Using simple assumptions on the validity of the Deser-Gilbert-Sudarshan (DGS) representation for the structure functions of deep-inelastic scattering and using the Bjorken-Johnson-Low theorem we show that in principle the LCC may be constructed knowing the experimental electron-proton scattering data. On the other hand, the scaling behavior of the structure functions is utilized to study the consistency of a vanishing value for various LCC under mild assumptions on the behavior of the DGS spectral moments.

Interaction between classical and quantum systems: A new approach to quantum measurement. III. Illustration
Following the approach to quantum measurement, proposed in an earlier paper, in which the apparatus is treated as a purely classical instrument to be described by the laws of classical mechanics we examine some simple experiments for the purpose of illustration. The Stern-Gerlach experiment is examined in detail, within our approach, and we see explicitly how the relevant information is transferred to the apparatus variables. We also examine a magnetic interferometer arrangement and a crossed-field arrangement. Consideration of these experiments leads us to the inclusion of an extra procedural step in our approach. This extra step is necessary so that an observer may measure the classical apparatus variables at will after the interaction is completed.

Isospin effects on the mass dependence of the balance energy
We study the effect of isospin degree of freedom on balance energy throughout the mass range between 50 and 350 for two sets of isotopic systems with N/A= 0.54 and 0.57 as well as isobaric systems with N/A= 0.5 and 0.58. Our findings indicate that different values of balance energy for two isobaric systems may be mainly due to the Coulomb repulsion. We also demonstrate clearly the dominance of Coulomb repulsion over symmetry energy.

Impact parameter dependence of isospin effects on the mass dependence of balance energy
We study the effect of isospin degree of freedom on the balance energy as well as its mass dependence throughout the mass range 48-270 for two sets of isobaric systems with N/Z = 1 and 1.4 using isospin-dependent quantum molecular dynamics (IQMD) model. Our fndings reveal the dominance of Coulomb repulsion in isospin effects on balance energy as well as its mass dependence throughout the range of the colliding geometry.
