Avila and Molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β(g). This work is a further investigation of generalized weak structures due to Avila and Molina. Further we introduce the structures ro(g) and rc(g) and study the properties of the structures r...

BACKGROUND Sigma (σ) receptors are membrane-bound proteins characterised by an unusual promiscuous ability to bind a wide variety of drugs and their high affinity for typical neuroleptic drugs, such as haloperidol, and their potential as alternative targets for antipsychotic agents. Sigma receptors display diverse biological activities and represent potential fruitful targets for therapeutic de...

We consider problems in finite-sample inference with two-step, monotone incomplete data drawn from Nd(μ,Σ), a multivariate normal population with mean μ and covariance matrix Σ. We derive stochastic representations for the distributions of μ̂ and Σ̂, the maximum likelihood estimators of μ and Σ, respectively. Under the assumption that Σ is block-diagonal when partitioned according to the two-step...

A new robust adaptive multiple models based fuzzy control scheme for a class of unknown nonlinear systems is proposed in this paper. The nonlinear system is expressed by using the Takagi–Sugeno (T–S) method, and some identification adaptive T–S models along with their corresponding controllers, are used in order to control efficiently the unknown system. The modeling error that is produced due ...

The expression of effective stress proposed by Terzaghi has always been questioned. Many correction formulas are modification pore pressure term. factor is related to porosity, contact area and other factors. When the particles in point contact, that Terzaghi, while for surface particles, actual increases produced passing through based on stress. There many factors affect development pressure, ...
