Original Concept

Abstract The term "cordillera" is being applied more and more frequently to structures whose origin was of lesser magnitude in terms of space, time, and behavior than the original concept of an orogenically active major element of submarine relief. When field observations do not reveal the presence of embryonic "nappes," the tendency is to consider the cordillera as representing a state of orogenic activity affecting a particular area of a geosyncline, during a variable time interval, which is not perforce related, at least not directly, with the breaking off of nappes. This modern approach is applied to an analysis of the inner French Alps.

Dilate Space

As a research tool, virtual environments (VEs) hold immense promise for brain scientists. Yet to fully realize this potential in non-human systems, theoretical and conceptual perspectives must be developed. When selectively coupled to nervous systems, virtual environments can help us better understand the functional architecture of animals’ brains during naturalistic behaviors. While this will no doubt allow us to further our understanding of the neural basis of behavior, there is also an opportunity to uncover the diversity inherent in brain activity and behavior. This is due to two properties of virtual environments: the ability to create sensory illusions, and the ability to dilate space and/or time. These and other potential manipulations will be characterized as the effects of virtuality. In addition, the systems-level outcomes of virtual environment enhanced perception will be discussed in the context of the uncanny valley and other expected relationships between emotional valence, cognition, and training. These effects and their usefulness for brain science will be understood in the context of three types of neurobehavioral phenomena: sensorimotor integration, spatial navigation, and interactivity. For each of these behaviors, a combination of illusory and space/time dilation examples will be reviewed. Once these examples are presented, the implications for improving upon virtual models for more directly inducing the mental phenomena of illusion and space/time dilation will be considered. To conclude, future directions for integrating the use of VEs into a strategy of broader biological inquiry will be presented.

Abstract The Pareto distribution satisfies the power law, which is widely used in physics, biology, earth and planetary sciences, economics, finance, computer science, and many other fields. In this article, the logarithmic Pareto distribution, a logarithmic transformation of the Pareto distribution, is presented and studied. The moments, percentiles, skewness, kurtosis, and some dynamic measures such as hazard rate, mean residual life, and quantile residual life are discussed. The parameters were estimated by quantile and maximum likelihood methods. A simulation study was conducted to investigate the efficiency, consistency, and behavior of the maximum likelihood estimator. Finally, the proposed distribution was fitted to some datasets to show its usefulness.

And Behavior

Many of the constructs of space, time and behavior in the ethnographic literature on hunter-gatherers may be partly determined by the severe constraints on ethnographic fieldwork. This paper discusses the genesis of some of these constructs, points out that the anthropological theory consumed by archaeologists is often based on, or developed for these constructs, and suggests that some of these constructs may be insensitive to deal with behavioral variability expressed in the archeological record, even though they can be made to fit any data. Their application to the archaeological record may merely be ethnography with a shovel in which the form and the structure of the ethnographic record are reproduced in the archaeological one.

The complex time WKB approximation is an effective tool in studying particle production in curved space–time. We use it in this work to understand the formation of classical condensate in expanding de Sitter space–time. The CWKB leads to the emergence of thermal spectrum that depends crucially on horizons (as in de Sitter space–time) or observer dependent horizons (as in Rindler space–time). A connection is sought between the horizon and the formation of classical condensate. We concentrate on de Sitter space–time and study the cosmological perturbation of k = 0 mode with various values of m/H0. We find that, for a minimally coupled free scalar field for [Formula: see text], the one-mode occupation number grows more than unity soon after the physical wavelength of the mode crosses the Hubble radius and soon after that, diverges as [Formula: see text], where [Formula: see text]. The results substantiate the previous works in this direction. We also find the correct oscillation and behavior of N(z) at small z from a single expression using CWKB approximation for various values of m/H0. We also discuss decoherence in relation to the formation of classical condensate. We further find that the squeezed state formalism and CWKB method give identical results.

PurposeThis paper aims to establish a theoretic framework to provide a fundamental understanding of cyberspatial objects, their existence and their identification scheme while providing a connection between cyber-enabled spaces and cyberspace. It develops an avenue to quantify general philosophical and theoretical questions, precisely, inherently spatial basis that produces an unprecedented space–time continuum, in which cyber-enabled relations evolve.Design/methodology/approachMultidisciplinary theoretical approaches are needed to describe complex systems, which in this paper are integrated in a quest for the principles underlying the structural organization and dynamics of cyberspace. A theoretic framework is presented, and the spatial conception of cyber-enabled physical, social, information and thinking spaces and entities existence are provided.FindingsWith spatial objects and spatial properties, cyberspace is inherently spatial. Its basic constructs are founded on its spatial qualities and producing radical space–time compression, cyber-enabled spaces in which dynamic relations develop and thrive. The cyberspatial object operations are primarily built on foundations that depend on physical space and other spatial metaphors. Information space, basically missing in the literature, is an important part of cyberspace.Research limitations/implicationsThis work suggested a novel analytical approach to describing cyberspace from broader perspectives and fields. Due to the novelty and divergence of cyber concepts, an interdisciplinary study and methodology are needed. Thus, more research toward theoretical direction could help many of the practical implementations of concepts.Practical implicationsThe research is of particular significance in cyberspatial mechanics to describe the dynamics and behavior of cyber physical systems. For example, object-based analysis functions like spatial query, node pattern analysis, cluster analysis, spatial similarity analysis and location modeling.Originality/valueComplementing the existing literature and defining information space to the research sphere, a theoretical framework providing a fundamental understanding of cyberspatial objects and the general cyberspace foundation has been proposed, resulting in a formalized concept of existence, interactions and applications and services, with respect to philosophy, science and technology, respectively.
