Analysis of Text Non-Homogeneity Using Markers

open access: yesLithuanian Journal of Statistics, 2015
The aim of the paper is to assess the distributional non-homogeneity of texts in the usage of functional words andother linguistic units. Our empirical study is based on recommended school fiction works taken from a digital library athttp://ebiblioteka ...

Kantian fractionalization predicts the conflict propensity of the international system [PDF]

open access: yes, 2014
The study of complex social and political phenomena with the perspective and methods of network science has proven fruitful in a variety of areas, including applications in political science and more narrowly the field of international relations.

Novel Integrated Sources for Short-reach Transmission Over Dispersive Channel [PDF]

open access: yesThe International Photonics and Optoelectronics Meeting (POEM), 2018
We review our recent results on Si or III-V integrated devices in novel transmitter architectures for IM-DD dispersion-uncompensated links. Methods relying on chirp engineering or SSB generation are demonstrated for multi- and single-carrier modulation formats.

Clustering over‐dispersed data with mixed feature types

open access: yesStatistical Analysis and Data Mining: The ASA Data Science Journal, 2018
Despite many data clustering methods are available, most of them uncover compactness or connectivity as the intrinsic structure of unlabeled data. Very few approaches explicitly consider the cluster size distribution, especially over‐dispersed (high variance), which may represent yet another important aspect of structural information of unlabeled data.

The Random Walk of High Frequency Trading [PDF]

open access: yes, 2014
This paper builds a model of high-frequency equity returns by separately modeling the dynamics of trade-time returns and trade arrivals. Our main contributions are threefold.

Study on Dispersion of Carbon Dioxide over the Shrubbery Region

open access: yesFrontiers in Energy Research, 2021
In the carbon capture and storage (CCS) infrastructure, the risk of a high-pressure buried pipeline rupture possibly leads to catastrophic accidents due to the release of tremendous amounts of carbon dioxide (CO2).

Investigating over-dispersion; Moniliformis (Acanthocephala) and rats

open access: yesParasitology, 1984
SUMMARYAn analysis of the frequency distribution of numbers of Moniliformis dubius in rats of an outbred strain of Wistar origin (CFHB) and feeding ad libitum on Oxoid 41B diet, showed that over-dispersion occurred regardless of the age and sex of the rats and the infective dose given (12, 20 or 40 cystacanths/rat). Over-dispersion was also shown to be

Dispersion management in nonlinear photonic crystal fibres with nanostructured core [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2011
The subwavelength structure of the core of a photonic crystal fibre can modify its dispersion characteristic and significantly shift the zero dispersion wavelength.

Burst-by-burst adaptive wireless video telephony over dispersive channels [PDF]

open access: yesSeamless Interconnection for Universal Services. Global Telecommunications Conference. GLOBECOM'99. (Cat. No.99CH37042), 2003
The video performance benefits of burst-by-burst adaptive modulation are studied, employing a higher-order modulation mode, when the channel is favourable, in order to increase the system's bits per symbol throughput and conversely, invoking a more robust, lower-order modulation mode, when the channel exhibits inferior channel quality. It is shown that

Dispersion of cognitive performance test scores on the MATRICS Consensus Cognitive Battery: A different perspective

open access: yesSchizophrenia Research: Cognition, 2022
Objective: Persons with schizophrenia exhibit greater neurocognitive test score dispersion. Here, we seek to characterize dispersion on the Neurocognitive Composite subtests of the Measurement of Treatment Research to Improve Cognition in Schizophrena ...
