We describe a mechanically checked proof that the Boyer-Moore fast string searching algorithm is correct. This is done by expressing both the fast algorithm and the naïve (obviously correct) algorithm as functions in applicative Common Lisp and proving them equivalent with the ACL2 theorem prover. The algorithm verified differs from the original Boyer-Moore algorithm in one key way: the origina...

We apply the Boyer–Moore technique to compressed pattern matching for text string described in terms of collage system, which is a formal framework that captures various dictionary-based compression methods. For a subclass of collage systems that contain no truncation, our new algorithm runs in O(‖D‖ + n · m + m + r) time using O(‖D‖ + m) space, where ‖D‖ is the size of dictionary D, n is the c...

Back Cover: In article 2200377, Cyrille Boyer and co-workers show the antimicrobial polymers as a promising approach to combat multidrugresistant pathogens. A library of 31 amphiphilic ternary containing different cationic groups, including primary amine, guanidine, sulfonium is prepared investigate impact groups on activity cytotoxicity against mammalian cells.

The Boyer-Moore algorithm is to solve exact string matching. Here, the Bad Character Rule of the Boyer-Moore algorithm is extended to solve approximate string matching. Although Tarhio and Ukkonen introduce a basic algorithm, it is similar to the Horsool algorithm. We utilize the concept of their algorithm to implement the Bad Character Rule, and we will obtain a new shift length. When the wind...

Continuing a line of work initiated in (Boyer et al., 2007), the generalisation of stochastic string distance to a stochastic tree distance is considered. We point out some hitherto overlooked necessary modifications to the Zhang/Shasha tree-distance algorithm for all-paths and viterbi variants of this stochastic tree distance. A strategy towards an EM cost-adaptation algorithm for the all-path...

We present the method of group foliation for constructing non-invariant solutions of partial differential equations on an important example of the Boyer-Finley equation from the theory of gravitational instantons. We show that the commutativity constraint for a pair of invariant differential operators leads to a set of non-invariant solutions of this equation. In the second part of the paper we...

A synchronous, hierarchical, occurrence-oriented, hardware description language (HDL) has been formalized with the Boyer-Moore logic. Well-formed HDL circuits are recognized by a predicate, and a unit-clock simulator de nes the meaning of circuits expressed in the HDL. This HDL has been used to specify an implementation of the FM9001 microprocessor that has been mechanically proved to implement...

In the opening of their book Hyposubjects: On becoming human, Morton and Boyer (2021) prepare reader that “what follows is an exercise in flimsy chaotic thinking” (13). As introductions go, it certainly unusual, irreverent astute assessment how unfolds.

background: fascioliasis, caused by fasciola hepatica and f. gigantica , is one of the most important plant and water borne disease in iran. this study aimed to determine the prevalence of fascioliasis and intestinal helminthes in inhabitants of rural areas of boyer-ahmad in kohgiluyeh and boyer-ahmad province in southwest of iran. methods: stool samples (1025) were collected from inhabitant of...
