The gene for cytosolic phosphoenolpyruvate carboxykinase (GTP) (EC 4.1.1.32) from the chicken was isolated from a recombinant library containing the chicken genome in phage lambda Charon 4A. The isolated clone, lambda PCK1cc, contains the complete gene for the enzyme as well as both 5' and 3' flanking sequences. The gene is approximately 8 kilobases in length divided into 8 exons, as demonstrat...

The two species of covalently closed circular DNA molecules of bovine leukemia virus were cloned in the lambda phage vector lambda gtWES X lambda B. Of the nine independent recombinant lambda-bovine leukemia virus clones that were analyzed, three were derived from the small and six were derived from the large circular molecules carrying, respectively, one and two copies of the long terminal rep...

Abstract We consider a Dirichlet problem driven by ( p z ), q ))-Laplacian and reaction involving the sum of parametric singular term plus superlinear perturbation. prove bifurcation-type result describing changes in set positive solutions as parameter $$\lambda &gt;0$$ ? &gt; 0</mml:m...

While higher-order pattern unification for the λ-calculus is decidable and unique unifiers exists, we face several challenges in practice: 1) the pattern fragment itself is too restrictive for many applications; this is typically addressed by solving sub-problems which satisfy the pattern restriction eagerly but delay solving sub-problems which are non-patterns until we have accumulated more in...

We consider transverse shear flow over a $2L$ -periodic array of air-filled grooves, which are separated by solid slats. address the scenario where liquid partially invades grooves. Following Crowdy's solution longitudinal problem ( J. Fluid Mech. vol. 925, 2021, R2), we focus upon simplified geometry infinitely narrow For flat menisci, ratio $\lambda$ slip length to $L$ depends single geometri...

In nominal syntax, variable binding is specified using atomabstraction constructors, and alpha-equivalence is formalised using fresh-ion constructors, and alpha-equivalence is formalised using freshness constraints and atom swappings, which implement variable renamings. Composition of swappings gives rise to atom permutations. Algorithms to check equivalence, match and unify nominal terms have ...

We present a new class of second-order unification problems, which we have called linear. We deal with completely general second-order typed unification problems, but we restrict the set of unifiers under consideration: they instantiate free variables by linear terms, i.e. terms where any λ-abstractions bind one and only one occurrence of a bound variable. Linear second-order unification proper...
