Let R be a Noetherian ring, I and J two ideals of R, m.an R-m.dule and t an integer. Let S be a Serre subcategory of the category of R-m.dules satisfying the co ondition CI, and N be a finitely generated R-m.dule with SuppRN= V（a） for som. a ∈ W（I, J）. It is sh.wn that if ExtR^J（N,HI^i,J（m.） ∈ S for all i 〈 t and all j 〈 t - i, then Ha^i（m. ∈ S for all i 〈 t. Let S be the class of all R-m.dules N with divm. N ≤ k, where k is an integer. It is proved that if Ha^i（m. ∈ S for all i 〈 t and all a ∈ W（I, J）, then HI^i,j（m. ∈ S for all i 〈 t. It follows that inf{i ： HI^i,j（m. S} = inf（inf{i ： Ha^i（m. S）： a ∈W（I,J）}.

A theoretical study of the dynam.cal behaviors of the interaction between a two-level atom.with a m.rse potential in the fram.work of the Jaynes Cum.ings m.del （JCm. is discussed. We sh.w that this system.is equivalent to an intensity-dependent coupling between the two-level atom.and the non-deform.d single-m.de radiation field in the presence of an additional nonlinear interaction. We study the dynam.cal properties of the system.such as, atom.c population inversion, the probability distribution of cavity-field, the m.ndel param.ter and atom.c dipole squeezing. It is sh.wn how the depth of the m.rse potential can be affected by non-classical properties of the system. m.reover, the tem.oral evolution of the Husim.-distribution function is explored.

Let R = ⊙n〉0 Rn be a standard graded ring, a ∩ ⊙n〉0 Rn an ideal of R, and m. N two finitely generated graded R-m.dules. This paper studies the hom.geneous com.onents of graded generalized local cohom.logy m.dules. We sh.w that for any i 〉 0, the n-th graded com.onent Hiα（m. N）n of the i-th generalized local cohom.logy m.dule of m.and N with respect to a vanish.s for all n 〉〉 0. Som. sufficient conditions are pro- posed to satisfy the equality sup{end（Hiα （m. N）） [ i _〉 0} = sup{end（HiR＋（m. N））｜ i 〉 0}. Also, som. sufficient conditions are proposed for the tam.ness of Hiα（m. N） such that i = fRα＋（m.N） or i = cdα（m.g）, where fRα＋（m.N） and cdα（m.g） denote the R＋- finiteness dim.nsion and the cohom.logical dim.nsion of m.and N with respect to a, respectively. Finally, we consider the Artinian property of som. subm.dules and quotient m.dules of Hjα（m. N）, where j is the first or last non-m.nim.x level of Hiα（m. N）.

Sm.ll high-quality Au/n type-GaAs Schottky barrier diodes （SBDs） with low reverse leakage current are produced using lithography. Their effective barrier heights （BHs） and ideality factors from.current-voltage （I-V） characteristics are m.asured by a Pico am.ere m.ter and hom.-built I-V instrum.nt. In spite of the identical preparation of the diodes there is a diode-to-diode variation in ideality factor and barrier height param.ters. m.asurem.nt of topology of a surface of a thin m.tal film.with atom.c force m.croscope （AFm. sh.ws that Au-n type-GaAS SD consists of a set of parallel-connected m.cro and nanocontacts diodes with sizes approxim.tely in a range of 100-200 nm. Between barrier height and ideality factor there is an inversely proportional dependency. With the diam.ter of contact increasing from.5 μm.up to 200 μm. the barrier height increases from.0.833 up to 0.933 eV and its ideality factor decreases from.1.11 down to 1.006. These dependencies sh.w the reduction of the contribution of the peripheral current with the diam.ter of contact increasing. We find the effect of series resistance on barrier height and ideality factor.
