In this study, we introduce a property (P) and the generalized interpolative contractions of types I, II, III, IV. We investigate certain conditions for existence fixed points contractions. derive several new results from main theorems. As an application, resolve Urysohn integral equation.
We provide evidence for a rational account of language production, Uniform Information Density (UID, Jaeger, 2006; Levy & Jaeger, 2007). Under the assumption that communication can usefully be understood as information transmission over a capacity-limited noisy channel, an optimal strategy in language production is to maintain a uniform rate of information transmission close to the channel capa...
Cryogenic cooling of macromolecular crystals is commonly used for X-ray data collection both to reduce crystal damage from radiation and to gather functional information by cryogenically trapping intermediates. However, the cooling process can damage the crystals. Limiting cooling-induced crystal damage often requires cryoprotection strategies, which can involve substantial screening of solutio...
In this paper, generalized convex contractions on orthogonal metric spaces are stablished in whath might be called their definitive versions. Also, we show that there are examples which show that our main theorems are genuine generalizations of Theorem 3.1 and 3.2 of [M.A. Miandaragh, M. Postolache and S. Rezapour, {it Approximate fixed points of generalized convex contractions}, Fixed Poi...
In this paper, a new stratification of mappings, which is called $Psi$-simulation functions, is introduced to enhance the study of the Suzuki type weak-contractions. Some well-known results in weak-contractions fixed point theory are generalized by our researches. The methods have been appeared in proving the main results are new and different from the usual methods. Some suitable examples ar...
Clonidine is a classically categorized α2-adrenoceptor (α2-AR) agonist that produces vascular contractions by stimulating arterial smooth muscle α2-ARs. However, clonidine inhibits α1-AR-mediated arterial contractions. Recently, it was suggested that repeated stimulation with clonidine induces desensitization of α2-ARs, thus inhibiting noradrenaline-induced smooth muscle contractions. In the pr...
Interdigestive contractile activity of the gastric body, antrum, pyloric ring and duodenum was recorded by means of chronically implanted force transducers in 5 conscious dogs. In accordance with interdigestive phase III contractions in the gastroduodenal region, a burst of strong contractions and remarkable relaxations were observed to occur in the pyloric ring. In accordance with the intense ...
Belief revision is increasingly being seen as central to a number of fundamental problems in Artificial Intelligence such as nonmonotonic reasoning, reasoning about action, truth maintenance and database update. This paper describes the first implementation of an AGM belief revision system. The system is based on classical firstorder logic, and for any finitely representable belief state, it ef...
We extend homological perturbation theory to encompass algebraic structures governed by operads and cooperads. Specifically, for an operad O, we define the notion of an ‘O-algebra contraction’ and we prove that the formulas of the Basic Perturbation Lemma preserve O-algebra contractions. Over a ground ring containing the rational numbers, we give explicit formulas for constructing an O-algebra ...
