    "Measurement of 2- and 3-nucleon short range correlation probabilities in nuclei" claimed to observe plateaus in the inclusive A/3He (e,e') ratios in the xB > 2 region; yet, a subsequent measurement at a higher momentum transfer did not observe xB > 2 plateaus. Herein we comment on a possible experimental explanation for this discrepancy.Comment: 1 page, 2 figure

    Quantitative Relationships of Terrestrial Mosses with Some Coniferous Forests at Mt. Rainier National Park

    Relatively few studies have been made on the correlation of moss societies with tree species in climax associations in North America; this is true despite the fact that in Europe moss unions have been accorded considerable importance along with societies of larger plants in delimiting phytocoenoses. The present study is an attempt to characterize as accurately as possible the terrestrial moss communities of typical climax stands in a given area, largely in Mt. Rainier National Park, and to discover how closely related bryophyte occurrence, frequency, and coverage may be to the societies of higher plants

    The EMC Effect and High Momentum Nucleons in Nuclei

    Recent developments in understanding the influence of the nucleus on deep-inelastic structure functions, the EMC effect, are reviewed. A new data base which expresses ratios of structure functions in terms of the Bjorken variable xA=AQ2/(2MAq0)x_A=AQ^2/(2M_A q_0) is presented. Information about two-nucleon short-range correlations from experiments is also discussed and the remarkable linear relation between short-range correlations and teh EMC effect is reviewed. A convolution model that relates the underlying source of the EMC effect to modification of either the mean-field nucleons or the short-range correlated nucleons is presented. It is shown that both approaches are equally successful in describing the current EMC data.Comment: 31 pages, 11 figure
