$n$-cocoherent rings‎, ‎$n$-cosemihereditary rings and $n$-V-rings

 Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted‎, ‎it is called a right co-$(n,d)$-ring if every right $R$-module is $(n‎, ‎d)$-projective‎. ‎$R$...

Recent N Results From J/ψ Decays

Based on 7.8 million J/ψ events collected at BEPC, the events for J/ψ → pp̄π and pp̄η have been selected and reconstructed. Clear peaks are observed around 1480 MeV in pπ(p̄π) invariant mass spectrum and near the threshold for η production in pη(p̄η) invariant mass spectrum. A partial wave analysis of J/ψ → pp̄η data has been performed. Two J = 1 2 − resonances are observed with mass and width (M, Γ...

Fables and Satires

ever they recognize its worth, but which he in his wisdom preserved. Sir Ronald Ross has done well to publish these verses, and among them will be found nothing that can be confused with the work of that School of Poetry which, largely by its self-advertisement, has been so conspicuous since the outbreak of the Great War. As a poet he belongs assuredly to the right wing, and to-day his verse mi...
