— A characterization oj decreasing rational transductions is given, We show that x is a decreasing rational transduction jrom X* into Y* if and only ij there exist an alphabet Z, two alphabetic morphisms h:Z* -> X*,g:Z* -» Y*t with h e-jree and a regular language R o Z* such that x = go(nR)oh~. Résumé. — Nous proposons une caracterisation des transductions rationnelles décroissantes. Nous montr...

Pushdown systems with transductions (TrPDSs) are an extension of pushdown systems (PDSs) by associating each transition rule with a transduction, which allows to inspect and modify the stack content at each step of a transition rule. It was shown by Uezato and Minamide that TrPDSs can model PDSs with checkpoint and discrete-timed PDSs. Moreover, TrPDSs can be simulated by PDSs and the predecess...

We define two classes of functions, called regular (respectively, first-order) list functions, which manipulate objects such as lists, lists of lists, pairs of lists, lists of pairs of lists, etc. The definition is in the style of regular expressions: the functions are constructed by starting with some basic functions (e.g. projections from pairs, or head and tail operations on lists) and putti...

Despite significant improvements in lentivirus (LV) vector-based gene therapy there are still several safety risks using LV vectors including the potential formation of replication-competent LV particles. To address this shortcoming, we constructed a novel and safer gene transfer system using modified SIN-based LV gene transfer vectors. Central to our approach is a conditional deletion of the Ψ...

This article discusses the concept of Biomimicry, which has been applying in many fields, from nanotechnology to robotics. It is appearing smart materials and machinic intelligence, for diverse purposes, being inspired by natural processes organisms. The main application Biomimicry produce artifacts ideas what we can know about nature already done. While mimesis removed vocabulary Art, works so...

OBJECTIVES To construct a specific database for the neuro-endocrine-immune (NEI) interactions. METHODS/RESULTS Version 1.0 database for neuro-endocrine-immune (dbNEI) serves as a web-based knowledge resource specific for the NEI systems. dbNEI collects 1,058 NEI related signal molecules, their 940 interactions and 72 affiliated tissues from the Cell Signaling Networks database, manually selec...
