The article is devoted to the problem of automation long volatility trading in financial market using delta-neutral strategies. Most operations on them, as a rule, are performed manually, which makes them less systematic and vulnerable negative influence human factor (emotions, tardiness actions, erroneous submission applications, etc.). To solve this problem, proposes unified algorithm for str...

Standard models of population dynamics focus on the interaction, survival, and extinction of the competing species individually. Real ecological systems, however, are characterized by an abundance of species (or strategies, in the terminology of evolutionary-game theory) that form intricate, complex interaction networks. The description of the ensuing dynamics may be aided by studying associati...

We examine a strategy for using neutral current measurements in longbaseline neutrino oscillation experiments to put limits on the existence of more than three light, active neutrinos. We determine the relative contributions of statistics, cross section uncertainties, event misidentification and other systematic errors to the overall uncertainty of these measurements. As specific case studies, ...

Strategy-proof allocation of a ®nite number of indivisible goods among a ®nite number of individuals is considered. The main result is that in a pure distributional case, a mechanism is strategy-proof, nonbossy and neutral if and only if it is serially dictatorial. If the indivisible goods are initially owned by the individuals, a mechanism is strategy-proof, individually rational and Pareto co...

Domains of generalized single-peaked preferences are classified in terms of the extent to which they enable well-behaved strategy-proof social choice. Generalizing the Gibbard-Satterthwaite Theorem, we characterize the domains that admit non-dictatorial strategy-proof social choice functions. We also provide characterizations of the domains that enable locally non-dictatorial, anonymous, and ne...

from applied linguistic point of view, the fundamental question facing the language teachers, methodologists and course designers is which procedure is more effective in fl/sl: learning to use or using to learn? definitely, in order to be a competent language user, knowledge of language system is necessary, but it is not sufficient to be a successful language user. that is why there was a gradu...

BACKGROUND Although several aspects of emotion seem to be intact in schizophrenia, there is emerging evidence that patients show an impaired ability to adaptively regulate their emotions. This event-related potential (ERP) study examined whether schizophrenia is associated with impaired neural responses to appraisal frames, that is when negative stimuli are presented in a less negative context....

there are different strategies for selecting stocks, and different investors use different strategies according to their risk tolerance or their expected rate of return. in this study, the profitability of a broad range of stock se-lection strategies in tehran stock exchange over the period 1370-1383, has been examined, and it has been investigated whether the successful strategies in other cou...
