BACKGROUND Despite its accuracy, the model for end-stage liver disease (MELD), currently adopted to determine the prognosis of patients with liver cirrhosis, guide referral to transplant programmes and prioritise the allocation of donor organs, fails to predict mortality in a considerable proportion of patients. AIMS To evaluate the possibility to better predict 3-month liver disease-related ...

background liver transplantation (lt) is the only treatment option for patients with advanced liver disease. currently, liver donation to these patients, considering priorities, is based on the model for end-stage liver disease (meld). meld score is a tool for predicting the risk of mortality in patients with advanced liver disease. however, few studies have so far been conducted in iran on the...

Theories of verisimilitude have routinely been classified into two rival camps—the content approach and the likeness approach—and these appear to be motivated by very different sets of data and principles. The question thus naturally arises as to whether these approaches can be fruitfully combined. Recently Zwart and Franssen (Synthese 158(1):75–92, 2007) have offered precise analyses of the co...

We develop a generalized method of moments (GMM) approach for fast parameter estimation in a new class of Dirichlet latent variable models with mixed data types. Parameter estimation via GMM has been demonstrated to have computational and statistical advantages over alternative methods, such as expectation maximization, variational inference, and Markov chain Monte Carlo. The key computational ...

We present several simple probabilistic data structures for implementing priority queues. We present a data structure called simple bottom-up sampled heap (SBSH), supporting insert in O(1) expected time and delete, delete minimum, decrease key and meld in O(log n) time with high probability. An extension of SBSH called BSH1, supporting insert and meld in O(1) worst case time is presented. This ...

Linear Meld is a concurrent forward-chaining linear logic programming language where logical facts can be asserted and retracted in a structured way. The database of facts is partitioned by the nodes of a graph structure which leads to parallelism if nodes are executed simultaneously. Communication arises whenever nodes send facts to other nodes by fact derivation. We present an overview of the...
