Abstract
We design a reversible version of truly concurrent process algebra CTC which is called RCTC. It has good properties modulo several kinds of strongly forward-reverse truly concurrent bisimulations and weakly forward-reverse truly concurrent bisimulations. These properties include monoid laws, static laws, new expansion ...

Introduction
Process algebras are well-known formal theory based on the so-called interleaving bisimilarity, such as CCS and ACP . We did some works on truly concurrent process algebra, which is called CTC .Reversible computation is another interesting topic, there are researches on reversible computation by use of communication ke...

CTC is a calculus of truly concurrent systems. It includes syntax and semantics:Its syntax includes actions, process constant, and operators acting between actions, like Prefix, Summation, Composition, Restriction, Relabelling.

The computation performance of random homologous code ensembles was studied using a suboptimal joint typicality decoder in , . For completeness, we first describe the joint typicality decoding rule and then characterize the rate region achievable by the (p,\epsilon )-distributed random homologous code ensemble under th...

We then discuss the limit of this outer bound as \epsilon \rightarrow 0 to establish an outer bound on the rate region {R}^*(p). Given an input pmf p and \delta >0, we define the rate region {R}^{**}(p,\delta ...

For the linear computation problem, the outer bound on the optimal rate region presented in Section  is valid for any computation, not only for natural computation. The inner bound presented in Theorem REF , however, matches with this outer bound only for natural computation. It is an interesting but difficult problem ...

Proof of Lemma
Since \epsilon ^{\prime } > \epsilon and \operatorname{\textsf {P}}({\tilde{E}}_n=1) tends to one as n \rightarrow \infty , by the conditional typicality lemma in , \operatorname{\textsf {P}}({\tilde{F}}_n=1) tends to one as n \rightarrow \infty .

Abstract
Marginal structural models (MSMs) allow for causal analysis of longitudinal data. The MSMs were originally developed as discrete time models. Recently, continuous-time MSMs were presented as a conceptually appealing alternative for survival analysis. In applied analyses, it is often assumed that the theoretical treatme...

Outline
MSMs can be used to obtain causal effect estimates in the presence of confounders, which e.g. may be time-dependent . The procedure is particularly appealing because it allows for a sharp distinction between confounder adjustment and model selection : first, we adjust for observed confounders by weighing the observed d...

Motivation
We will present a strategy for dealing with confounding and dependent censoring in continuous time. Confounding, which may be time-varying, will often be a problem when analysing observational data, e.g. coming from health registries. The underlying goal is to assess the effect a treatment strategy has on an outcome.We...

Hypothetical scenarios and likelihood ratios
We consider observational event-history data where n i.i.d. subjects are followed over the study period [0,T]. Let N^{i,A} \text{ and } N^{i,D} respectively be counting processes that jump when treatment A and outcome D of interest occur for subject i. Furthermore, let Y^{i,A},Y^{i,D} be the at-risk processes for A and...

We stress that we consider the intensity process marginalized over \mathcal {L}, and thereby it is defined with respect to \mathcal {F}_t ^{i, \mathcal {V}_0}, and not \mathcal {F}_t ^{i, \mathcal {V}_0 \cup \mathcal {L}}.

Re-weighted additive hazard regression
Our main goal is to estimate the cumulative coefficient function in (REF ), i.e.B_t := \int _0^t b_s dsfrom the observational data distributed according to P = P^1 \otimes \dots \otimes P^n. If we had known all the true likelihood ratios, we could try to estimate (REF ) by re-weighting each individual in Aalen's additi...

Parameters that are transformations of cumulative hazards
It has recently been emphasised that the common interpretation of hazards in survival analysis as the causal risk of death during (t, t + \Delta ] for an individual that is alive at t, is often not appropriate; see e.g. . An example in shows that this can also be a problem in RCTs; if N is a counting process that jumps...

Consistency and P-UT property
Condition \ref {eq:consistW}) states that the weight estimator converges to the theoretical weights R_t^i, in a not very strong sense. The uniform boundedness of \lbrace R^i \rbrace _i is a positivity condition similar to the positivity condition required for standard inverse probability weighting.

Estimation of weights using additive hazard regression
For each i, \lim _{ \delta \rightarrow 0} P \big ( \inf \limits _{t \le T} | \tilde{Z}_t^{i\intercal } \tilde{h}_t | \le \delta \big ) = 0, E\big [\sup \limits _{s \le T} |Z_{s}^i|^3_3 \big ] < \infty and E\big [\sup \limits _{s \le T} |\tilde{Z}_{s}^i|^3_3 \big ] < \infty for every i \lim _{a \rightarrow \infty...

Software
We have developed R software for estimation of continuous-time MSMs that solve ordinary differential equations, in which additive hazard models are used to model both the time to treatment and the time to the outcome of interest. Our procedure involves two steps: first, we estimate continuous-time weights using fitted ...
