It is well established that a formal language generated from a unimodal map is regular if and only if the map’s kneading sequence is either periodic or eventually periodic. A previously proposed conjecture said that if a language generated from a unimodal map is context-free, then it must be regular, i.e. there exists no proper context-free language which can be generated from a unimodal map. T...

We provide a model for an open invariant neighborhood of any orbit in a symplectic manifold endowed with a canonical proper symmetry. Our results generalize the constructions of Marle [Mar84, Mar85] and Guillemin and Sternberg [GS84] for canonical symmetries that have an associated momentum map. In these papers the momentum map played a crucial role in the construction of the tubular model. The...

soil texture is an important soil physical property that governs most physical, chemical, biological, and hydrological processes in soils. detailed information on soil texture variability is crucial for proper crop and land management and environmental studies. therefore, at present research, 103 soil profiles were dogged and then sampled in order to prepare digital map of soil texture in bijar...

Genetically targeted anatomical and behavioral characterization of the cornu ammonis 2 (CA2) subfield of the mouse hippocampus

Let K be a global function field of characteristic p, with finite field of constants k (the algebraic closure of Fp in K) of size q, so K is the function field k(V ) of a unique smooth, proper, geometrically connected curve V over k. Let XK be a smooth proper geometrically connected curve over K, with genus g > 0. The Jacobian J = Pic0XK/K ofXK is an abelian variety overK with dimension g > 0. ...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

In answering questions from [7] we prove a triangulation result that is of independent interest. In more detail, let R be an o-minimal field with a proper convex subring V , and let st : V → k be the corresponding standard part map. Under a mild assumption on (R, V) we show that definable sets X ⊆ V n admit a triangulation that induces a triangulation of its standard part st(X) ⊆ k n .

Although language-impaired children have been observed to follow many nor­ mal language acquisition patterns, research to date has not fully explored the re­ lationships between various linguistic domains. The hypotheses investigated in this study are that language-impaired children produce fewer logical proposi­ tions per utterance and evidence less control of formal syntactic markers. lan­ gu...

In this note, we give a necessary and sufficient condition for the properness of moment maps representations quivers. We show that map quiver is proper if only acyclic, is, it does not contain any oriented cycle.
