PURPOSE
To evaluate our data concerning the prognostic factors for locoregional control, survival, late complications, and sphincter conservation in a series of epidermoid cancers of the anal canal without clinical evidence of metastasis.
METHODS AND MATERIALS
Between June 1972 and January 1997, 305 patients were treated with curative-intent radiotherapy… (More)

We consider a model of random walk in Z with (fixed or random) orientation of the horizontal lines (layers) and with non constant iid probability to stay on these lines. We prove the transience of the walk for any fixed orientations under general hypotheses. This contrasts with the model of Campanino and Petritis [3], in which probabilities to stay on these… (More)

Let T be an ergodic automorphism of the d-dimensional torus T. In the spirit of Le Borgne [10], we give conditions on the Fourier coefficients of a function f from T to R under which the partial sums f ◦T+f ◦T + · · ·+f ◦T n satisfies a strong invariance principle. Next, reinforcing the condition on the Fourier coefficients in a natural way, we obtain… (More)

PURPOSE
This cost analysis aimed to quantify the cost of IGRT in relation to IGRT frequency and modality with Cone Beam Computed Tomography (CBCT) or orthogonal electronic portal imaging with fiducial markers (EPI-FM).
MATERIAL AND METHODS
Patients undergoing IGRT for localized prostate cancer were randomized into two prostate control frequencies (daily… (More)

In this paper, we extend a result of Campanino and Pétritis [Markov Process. Relat. Fields 9 (2003) 391–412]. We study a random walk in Z with random orientations. We suppose that the orientation of the kth floor is given by ξk, where (ξk)k∈Z is a stationary sequence of random variables. Once the environment fixed, the random walk can go either up or down… (More)

PURPOSE
To evaluate the residual hematopoiesis at different levels of total body irradiation (TBI) dose in bone marrow (BM) and peripheral blood (PB), and to study the dose-effect relationship on hematopoietic immature and mature progenitors. We also investigated the possibility of expanding ex vivo the residual progenitors exposed to different dose levels… (More)

We consider some nonuniformly hyperbolic invertible dynamical systems which are modeled by a Gibbs-Markov-Young tower. We assume a polynomial tail for the inducing time and a polynomial control of hyperbolicity, as introduced by Alves, Pinheiro and Azevedo. These systems admit a physical measure with polynomial rate of mixing. In this paper we prove that… (More)

The motivation of this work is the study of the error term et (x,ω) in the averaging method for differential equations perturbed by a dynamical system. Results of convergence in distribution for ( e t (x,·) √ ε )ε>0 have been established in Khas’minskii [Theory Probab. Appl. 11 (1966) 211–228], Kifer [Ergodic Theory Dynamical Systems 15 (1995) 1143– 1172]… (More)

We consider the one-sided exit problem for stable Lévy process in random scenery, that is the asymptotic behaviour for T large of the probability P [ sup t∈[0,T ] ∆t ≤ 1 ]
