Cross sections for inclusive electron scattering from aluminum have been measured at both forward and backward angles in the kinematic region near x =1 and 1.75 & Q & 7 (GeV/c) . The forward-angle data are in good agreement with a recent calculation. Both the data and the calculation show scaling behavior for F2(g, Q~)=vs(g, Q2) at high Q for fixed values of the Nachtmann variable g. The ratio R =oL /trr has been extracted for 1.75 &Q &5 (GeV/c) and is found to decrease with Q2 to a value consistent with zero at the highest Q~.

The proton elastic electric and magnetic form factors, GEM and G’bfP(Q2), have been separately measured in the range Q” =1.75 to 8.83 (GeV/c)2, more than doubling the Q3 range of previous data. Scaled by the dipole fit, Go(Q2), the results for Gnlp(Q2)//+G~(Q2) d ecrease smoothly from 1.05 to 0.91, while G~p(Q~)lcdQ~) is consistent with unity. Comparisons are made to QCD Sum L-eRule, diquark, constituent quark, and VMD models, none of whic,h agree with all of the new data. The ratio Q2F2/Fl approaches a constant value for Q2 > 3 ( GeV/c)2. --p;. .- -- 2

We investigate the possibility of having horizons inside various classical field configurations. Using the implicit function theorem, we show that models satisfying a certian set of criteria allow for (at least) small horizons within extended matter fields. Gauge and global monopoles and Skyrmions satisfy these criteria. Q balls and boson stars are examples which do not and can be shown not to allow for horizons. In examples that do allow for horizons, we show how standard "no hair" arguments are avoided.
