There is a remarkable friction between drill string and borehole in extended-reach wells and horizontal wells due to large deviation angle, contact between drill string and borehole, non-rotation of drill string. The large friction and torque will in

In this paper, we construct a local linear composite quantile regression (CQR) estimator of regression function for left-truncated data, which extends the CQR method to the left-truncated model. The asymptotic normality of the proposed estimator is a

Let {X n } be a Markov chain with transition probability $$p_{ij} = a_{j - (i - 1)^ + } ,\forall i,j \geqslant 0$$ , where a j = 0 provided j < 0, a 0 > 0, a 0 + a 1 < 1 and Σ =0 ∞ a n = 1. Let µ = Σ =1 ∞ na n . It is known that {X n } is posi

This paper gives a characterization of a Hunt process path by the first exit left limit distribution. It is also showed that if the first exit left limit distribution leaving any ball from the center is a uniform distribution on the sphere, then the

Transience and recurrence are among the most important concepts in Markov processes. In this paper, we study the transience and recurrence for right processes with a given weight function, and characterize them by potentials, excessive functions, fir
