AIM Cardiac rehabilitation (CR) is a proven intervention that substantially improves physical health and decreases death and disability following a cardiovascular event. Traditional CR typically involves 36 on-site exercise sessions spanning a 12-week period. To date, the optimal dose of CR has yet to be determined. This study compared a high contact frequency CR programme (HCF, 34 on-site sess...

تمام ترکیبات اورانیم، سمی و رادیواکتیو هستند. بودن این عنصر می‌تواند کشنده باشد. با توجه به سمیت شیمیایی رادیواکتیویته ضروری است از ورود آن طبیعت جلوگیری شود. پسماندهای خروجی مراکز صنعتی- هسته­ای نیز دارای مقادیر مختلفی اورانیم می­باشد لذا حذف پساب اهمیت ویژه­ای برخوردار است. سویی دیگر، نظر محدودیت منابع آن، بازیابی پسماندها، ارزش اقتصادی می­باشد. در پژوهش حاضر، روش سطح پاسخ (RSM) بر اساس طرح م...

This paper studies the load sharing problem among heterogeneous cluster systems. The heterogeneous clusters we consider are time-sharing, and the computers in these clusters have different CPU powers and memory capacities. Load sharing means even workloads among all coordinated computers in the system. As some nodes suffer from high loading, it is necessary to migrate some jobs to the nodes wit...

Suppose we have been sold on the idea that formalised proofs in an LCF system should resemble their written counterparts, and so consist of formulas that only provide signposts for a fully verified proof. To be practical, most of the fully elaborated verification must then be done by way of general purpose proof procedures. Now if these are the only procedures we implement outside the kernel of...

HOLCF is the de nitional extension of Church s Higher Order Logic with Scott s Logic for Computable Functions that has been implemented in the theorem prover Isabelle This results in a exible setup for reasoning about functional programs HOLCF supports stan dard domain theory in particular xpoint reasoning and recursive domain equations but also coinductive arguments about lazy datatypes This p...

HOL Light is an interactive proof assistant for classical higherorder logic, intended as a clean and simplified version of Mike Gordon’s original HOL system. Theorem provers in this family use a version of ML as both the implementation and interaction language; in HOL Light’s case this is Objective CAML (OCaml). Thanks to its adherence to the so-called ‘LCF approach’, the system can be extended...

Jasmonates are ubiquitously occurring plant growth regulators with high structural diversity that mediate numerous developmental processes and stress responses. We have recently identified 12-O-β-D-glucopyranosyljasmonic acid as the bioactive metabolite, leaf-closing factor (LCF), which induced nyctinastic leaf closure of Samanea saman. We demonstrate that leaf closure of isolated Samanea pinna...

We show how LCF-style interactive theorem provers might use BDD engines and SAT solvers to perform normalization, simplification of terms and theorems, and assist with interactive proof. The treatment builds on recent work integrating SAT solvers as non-trusted decision procedures for LCF-style theorem provers. We limit ourselves to propositional logic, but briefly note that the results may be ...

The Satisfiability Modulo Theories (SMT) solver Z3 can generate proofs of unsatisfiability. We present independent reconstruction of these proofs in the theorem provers Isabelle/HOL and HOL4 with particular focus on efficiency. Our highly optimized implementations outperform previous LCF-style proof checkers for SMT, often by orders of magnitude. Detailed performance data shows that LCF-style p...
