Algorithmic Randomness for Infinite Time Register Machines

open access: yes, 2014
A concept of randomness for infinite time register machines (ITRMs), resembling Martin-L\"of-randomness, is defined and studied. In particular, we show that for this notion of randomness, computability from mutually random reals implies computability and

Verification using counterexample fragment based specification relaxation: case of modular/concurrent linear hybrid automata

open access: yesIET Cyber-Physical Systems, 2017
We present LhaVrf, a symbolic verifier for the safety verification of concurrent LHA (Linear Hybrid Automaton). A concurrent LHA is composed of a set of LHAs that interact through shared variables and/or events.

Computability and Analysis, a Historical Approach

open access: yes, 2016
The history of computability theory and and the history of analysis are surprisingly intertwined since the beginning of the twentieth century. For one, \'Emil Borel discussed his ideas on computable real number functions in his introduction to measure ...

Ptarithmetic [PDF]

open access: yes, 2009
The present article introduces ptarithmetic (short for "polynomial time arithmetic") -- a formal number theory similar to the well known Peano arithmetic, but based on the recently born computability logic (see http://www.cis.upenn.edu/~giorgi/cl.html ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Propositional computability logic I

open access: yes, 2004
In the same sense as classical logic is a formal theory of truth, the recently initiated approach called computability logic is a formal theory of computability. It understands (interactive) computational problems as games played by a machine against the

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Verifying the structure and behavior in UML/OCL models using satisfiability solvers

open access: yesIET Cyber-Physical Systems, 2016
Due to the ever increasing complexity of embedded and cyber-physical systems, corresponding design solutions relying on modelling languages such as Unified Modelling Language (UML)/Object Constraint Language (OCL) find increasing attention.

(HO)RPO Revisited [PDF]

open access: yes, 2006
The notion of computability closure has been introduced for proving the termination of the combination of higher-order rewriting and beta-reduction. It is also used for strengthening the higher-order recursive path ordering.

Computations in Space and Space in Computations [PDF]

open access: yes, 2005
The emergence of terms like natural computing, mimetic computing, parallel problem solving from nature, bio-inspired computing, neurocomputing, evolutionary computing, etc., shows the never ending interest of the computer scientists for the use of “natural phenomena” as “problem solving devices” or more generally, as a fruitful source of inspiration to
