simple harmonizable processes (shp) introduced by soltani and parvardeh (2006) are a large class of nonstationary processes which includes stationary and periodically correlated (pc) processes. detection and estimation of shp structure are important problems when dealing with nonstationary data. in this paper, we study the spectral properties of simple processes and propose a method to detect a...

this article aims at contrasting aspectual oppositions in english and persian in the context of the novel the old man and the sea, and its translation by daryabandari (1983) as the data. unlike english, in persian perfective and imperfective forms are morphologically marked. while the vast majority of english simple past forms are translated into persian by past perfective forms, only less than...

Life originated from unicellular organisms by circumventing the Second Law of Thermodynamics using the First Principles of Physiology, namely negentropy, chemiosmosis and homeostatic regulation of calcium and lipids. It is hypothesized that multicellular organisms are merely contrivances or tools, used by unicellular organisms as agents for the acquisition of epigenetic inheritance. The First P...

Some of the major outstanding problems in biology are related to issues of emergence and evolution. These include: (1) how do populations of organisms traverse their adaptive landscapes? (2) what is the relation between adaptedness and tness? (3) the formation of multi-cellular organisms from basic units or cells. In this paper we study these issues using a model which is both general and simpl...

This paper presents a proof-of-concept research into building an ontology of life-events in public administration and integration of this domain ontology with standard upper ontology. SUMO was chosen to be the upper ontology and SUO-KIF the language of both upper and domain ontology.

Does the very idea of “human dignity” entail some moral disrespect for nonhuman animals? Put otherwise, does the notion of “human dignity” smack of speciesism (roughly, a view whereby nonhuman, sentient individuals are denied [adequate] moral standing on essentially arbitrary grounds)? Animal advocates, like James Rachels, often allege that there is a serious clash between the traditional view ...

We describe a model of a stockmarket in which independent adaptive agents can buy and sell stock on a central market The overall market behavior such as the stock price time series is an emergent property of the agents behavior This approach to modelling a market is contrasted with conventional rational expectations approaches Our model does not necessarily converge to an equilibrium and can sh...

This article examines the spillover amplification hypothesis, which proposes that because people lower in self-complexity experience stronger responses to life events they will show relatively better well-being in the presence of positive factors (e.g., better social support) and relatively poorer well-being in the presence of negative factors (e.g., a history of negative experiences). Across t...

We describe a model of a stockmarket in which independent adaptive agents can buy and sell stock on a central market. The overall market behavior, such as the stock price time series, is an emergent property of the agents’ behavior. This approach to modelling a market is contrasted with conventional rational expectations approaches. Our model does not necessarily converge to an equilibrium, and...

Frequency-dependent selection may favour the evolution of mixed reproductive strategies, resulting in polymorphic life-histories within a population. Here I explore the theoretical and ecological possibilities for evolution of mixed reproductive strategies in two minimal age-structured life-history models. The first model addresses evolution of delayed maturity (i.e., competition between annual...
