Nil· a Perspective

چکیده
NIL is acronymic for "New Implementation of Lisp" (or possibly "Nil Is Lisp"). It is intended to be a modernization of the programming language LISP suitable in design for implementation on any of the current generation of large-address-space, low-cost computers; and maximally upward-compatible with MACLlSP, the dialect of LISP developed at the M.I.T Laboratory for Computer Science, and Artificial Intelligence Laboratory. Additionally, NIL attempts to be as compatible as is possible with the LISP Machine dialect ("L1SPM", also an upward-compatible extension of MACLISP see [Weinreb 1979]), given the restraining condition that NIL be easily implementable on hardware such as the Digital Equipment V AX 11/780, the experimental S-I developed at Stanford University under contract from the ONR, and some of the host of new 32-blt micros starting to appear now.

On the nil-clean matrix over a UFD
In this paper we characterize all $2times 2$ idempotent and nilpotent matrices over an integral domain and then we characterize all $2times 2$ strongly nil-clean matrices over a PID. Also, we determine when a $2times 2$ matrix over a UFD is nil-clean.
متن کاملStrongly nil-clean corner rings
We show that if $R$ is a ring with an arbitrary idempotent $e$ such that $eRe$ and $(1-e)R(1-e)$ are both strongly nil-clean rings, then $R/J(R)$ is nil-clean. In particular, under certain additional circumstances, $R$ is also nil-clean. These results somewhat improves on achievements due to Diesl in J. Algebra (2013) and to Koc{s}an-Wang-Zhou in J. Pure Appl. Algebra (2016). ...
متن کاملA note on uniquely (nil) clean ring
A ring R is uniquely (nil) clean in case for any $a in R$ there exists a uniquely idempotent $ein R$ such that $a-e$ is invertible (nilpotent). Let $C =(A V W B)$ be the Morita Context ring. We determine conditions under which the rings $A,B$ are uniquely (nil) clean. Moreover we show that the center of a uniquely (nil) clean ring is uniquely (nil) clean.
متن کاملAmelioration of rat renal ischemia/reperfusion injury by L-Nil
Introduction: Ischemia/reperfusion (IR) injury involves a complex interrelated sequence of events. High levels of nitric oxide (NO) are generated with inducible form of nitric oxide synthase (iNOS) leading to the renal IR injury and glutathione (GSH) depletion. The present study was designed to investigate the effect of L-Nil (N6- (1-Iminoethyl)-L- lysine.hydrochloride), a selective inhibito...
متن کاملSome Properties of the Nil-Graphs of Ideals of Commutative Rings
Let R be a commutative ring with identity and Nil(R) be the set of nilpotent elements of R. The nil-graph of ideals of R is defined as the graph AG_N(R) whose vertex set is {I:(0)and there exists a non-trivial ideal such that and two distinct vertices and are adjacent if and only if . Here, we study conditions under which is complete or bipartite. Also, the independence number of is deter...
