This theory contains some useful extensions to the LList theory by Larry Paulson, including finite, infinite, and positive llists over an alphabet, as well as the new constants take and drop and the prefix order of llists. Finally, the notions of safety and liveness in the sense of [1] are defined.

In many settings, randomly arriving objects are offered successively to agents according to their fixed order in a waiting list. Though it is costly to wait, an agent may prefer to decline an offered object in order to wait for a better one (e.g. as in perhaps the most significant of such environments, the assignment of donor organs to queued patients). We consider the welfare consequences of i...

In a recent article, Thompson 1] described the use of neighbour lists in simulations, giving a detailed account of the implementation and the resulting economies. This note deals with a simple variant on the method, and discusses the choice of neighbour list technique, if any, to be used in various circumstances. The idea was originally introduced in the classic paper of Verlet 2] on the simula...

We introduce a new data structure called symlist based on an idea of Tarjan [17]. A symlist is a doubly linked list without any directional information encoded into its cells. In a symlist the two pointers in each cell have no fixed meaning like previous or next in standard lists. Besides the common operations on doubly linked lists, symlists support the reversal of a list and the insertion of ...

In broadcasting, information originally held in one node of a communication network (called the source) has to be transmitted to a11 other nodes. In a unit of time, every node which already got the source message can transmit it to one neighbor. In classical broadcasting, the choice of neighbors to be informed by a node and the order in which they are informed may depend on the source. Thus, no...

BACKGROUND Assessing growth is a useful tool for defining health and nutritional status of children. The objective of this study was to construct growth reference curves of Iranian infants and children (0-6 years old) and compare them with previous and international references. METHODS Weight, height or length of 2107 Iranian infants and children aged 0-6 years old were measured using a cross...

BACKGROUND Cytochrome P450 2C19 (CYP2C19) is important in metabolism of wide range of drugs. CYP2C19*17 is a novel variant allele which increases gene transcription and therefore results in ultra-rapid metabolizer phenotype (URM). Distribution of this variant allele has not been well studied worldwide. The aim of present study was to investigate allele and genotype frequencies of CYP2C19*17 in ...

The Gilaki and Mazandarani occupy the South Caspian region of Iran and speak languages belonging to the North-Western branch of Iranian languages . It has been suggested that their ancestors came from the Caucasus region, perhaps displacing an earlier group in the South Caspian . Linguistic evidence supports this scenario, in that the Gilaki and Mazandarani languages (but not other Iranian lang...
