An enhanced production of strange particles per pion in heavy ion collisions compared to elementary p+p interactions was observed in Pb+Pb reactions at the CERN SPS. New results obtained on small colliding systems, C+C and Si+Si, also show an enhancement. It increases steeply with system size and reaches in the larger system almost the level measured in Pb+Pb reactions. The shapes of the transv...

Arranged by Yarom Gabay based on a seminar by Assaf Kfoury March 1, 2005 The references are to Barendregt’s book [1]. So far we have studied the λ-calculus as a rewrite-system , i.e., we have studied properties of reduction, specifically, β-reduction. We can also study the λ-calculus as an equational theory , i.e., an axiomatic system consisting of axioms and inference rules to produce valid eq...

In today’s systems and networks, disruption is inevitable. Designing a reliable system to overcome probable facility disruptions plays crucial role in planning management. This article proposes capacitated joint inventory-location problem where location-independent may occur facilities. The tries satisfy customer’s demands considers penalty costs for unmet customer demand. aims minimize total s...

Let $$ {\overline{\mathrm{X}}}_{\uplambda} be the closure of I-orbit in affine Grassmanian Gr a simple algebraic group G adjoint type, where I is Iwahori subgroup and λ coweight G. We find algorithm which describes set Ψ(λ) all I-orbits terms coweights. introduce R-operators (associated to positive roots) on lattice G, exactly describe relation I-orbits. These operators satisfy Braid relations ...

Site-directed scarless mutagenesis is an essential tool of modern pathogenesis research. We describe an optimized two-step protocol for genome editing in Salmonella enterica serovar Typhimurium to enable multiple sequential mutagenesis steps in a single strain. The system is based on the λ Red recombinase-catalyzed integration of a selectable antibiotics resistance marker followed by replacemen...

We propose an implementation of λ + , a recently introduced simply typed lambda-calculus with pairs where isomorphic types are made equal. The rewrite system of λ + is a rewrite system modulo an equivalence relation, which makes its implementation non-trivial. We also extend λ + with natural numbers and general recursion and use Beki´c's theorem to split mutual recursions. This splitting, toget...
