$n$-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. $R$...

We derive a combinatorial formula for quantized Donaldson-Thomas invariants of the m-loop quiver. Our main tools are the combinatorics of noncommutative Hilbert schemes and a degenerate version of the Cohomological Hall algebra of this quiver. 2010 Mathematics Subject Classification: Primary 16G20, secondary 05E05, 14N35

Equids are considered highly resistant to mycobacterial infections and clinical cases have been described in domestic horses only. Mycobacterium bovis is the most common species reported, although a single report exists of disease due to definitively diagnosed infection with Mycobacterium avium subsp. hominissuis in two domestic horses. This is the first report of a mycobacterial infection in a...
