let $s$ be an ordered semigroup. a fuzzy subset of $s$ is anarbitrary mapping   from $s$ into $[0,1]$, where $[0,1]$ is theusual interval of real numbers. in this paper,  the concept of fuzzygeneralized bi-ideals of an ordered semigroup $s$ is introduced.regular ordered semigroups are characterized by means of fuzzy leftideals, fuzzy right ideals and fuzzy (generalized) bi-ideals.finally, two m...

Intracellular recordings of cortical neurons in vivo display intense subthreshold membrane potential (Vm) activity. The power spectral density (PSD) of the Vm displays a power-law structure at high frequencies (>50 Hz) with a slope of about -2.5. This type of frequency scaling cannot be accounted for by traditional models, as either single-compartment models or models based on reconstructed cel...

where 3 is the centre of 51 and cl denotes closure in the norm topology. When 5t is a von Neumann algebra this result is already known (see [7; Lemma 9, p. 255], where the method requires only trivial modification to deal with the case of a left ideal), and the proof in that situation involves the restriction of an operator in M to a subspace on which it can be inverted. The proof given here fo...

Let S be a standard N-graded polynomial ring over a field k, let I be a multigraded homogeneous ideal of S, and let M be a finitely generated Z-graded Smodule. We prove that the resolution regularity, a multigraded variant of CastelnuovoMumford regularity, of IM is asymptotically a linear function. This shows that the well known Z-graded phenomenon carries to the multigraded situation.

The term ‘interoperability’ has been mentioned in various electronic communications fields. In short it represents the “ability to operate between parties”. ‘Interoperability’ is sometimes defined as “how data is effectively exchanged and utilised between devices”. This statement reflects only the situation in the Application Layer. Interoperability should be the concern of all layers. In Devic...

Let S be a standard N k-graded polynomial ring over a field K, let I be a multigraded homogeneous ideal of S, and let M be a finitely generated Z k-graded S-module. We prove that the resolution regularity, a multigraded variant of Castelnuovo-Mumford regularity, of I n M is asymptotically a linear function. This shows that the well known Z-graded phenomenon carries to multigraded situation.

Innominate artery rupture is a rare, but usually fatal, complication of tracheal stenosis. Although prevention is key, prompt, appropriate intervention can be life saving. Hemorrhage and airway must simultaneously be controlled. Most deaths occur from exsanguination with adequate ventilation before surgical repair can be effected. In the ideal situation, the event would occur in the operating r...

In this paper we study a discrete Raman laser amplification model given as a LotkaVolterra system. We show that in an ideal situation, the equations can be written as a Poisson system with boundary conditions using a global change of coordinates. We address the questions of existence and uniqueness of a solution. We deduce numerical schemes for the approximation of the solution that have good s...

Considers issues of qualitative and quantitative development of the world's technologists-economic structures and their forecast trends in the context of the earlier of the proposed law «aspirations of the economic systems of the ideal», and also places them in the economy of Ukraine. The analysis revealed the inadequacy of the existing innovative economic policy and sets out some of the aspect...

What are the factors that contribute to "ideal" instructional interactivity? In this study, subjects observed different interactive situations between a student and teacher, displayed in video format on a computer and were asked to subjectively rate the quality of interactivity for each situation. Analysis of pilot test data using multiple regression analysis showed a small but significant effe...
