This paper investigates the potential role of syllabic structure in characterising the informational content of running speech using an energy-based measure (the cochlea-scaled entropy, CSE index). We computed the CSE and compared how it aligned to the energy envelope for a corpus of English and Spanish sentences. We also compared these measures to syllabic structure, which differs markedly bet...

Laughter is increasingly present in biomedical literature, both in analytical neurological aspects and in applied therapeutic fields. The present paper, bridging between the analytical and the applied, explores the potential of a relevant variable of laughter’s acoustic signature—entropy—in the detection of a widespread mental disorder, depression, as well as in gauging the severity of its diag...

According to the thermodynamical analogy in black hole physics, the entropy of a black hole in the Einstein theory of gravity equals S BH = A H /(4l 2 P), where A H is the area of a black hole surface and l P = (¯ hG/c 3) 1/2 is the Planck length [1, 2]. In black hole physics the Bekenstein-Hawking entropy S BH plays essentially the same role an in the usual thermodynamics. In particular it all...

The quantum speed limit indicates the maximal evolution of system. In this work, we determine limits on informational measures, namely von Neumann entropy, information, and coherence systems evolving under dynamical processes. These ascertain fundamental limitations time required by for changes in their measures. Erasing information to reset memory future use is crucial computing devices. We ob...

This works deals with the presence of localized planar structures in magnetic materials that admit integer or half-integer topological charge. We study models which internal disposition magnetization is driven by a single parameter, controls charge density structure. In particular, we focus mainly on configurational entropy these skyrmions and half-skyrmions show how to increase diminish their ...

Entropy and other fundamental quantities of information theory are customarily expressed and manipulated as functions of probabilities. Here we study the entropy H and subentropy Q as functions of the elementary symmetric polynomials in the probabilities, and reveal a series of remarkable properties. Derivatives of all orders are shown to satisfy a complete monotonicity property. H and Q themse...

This Letter presents a new approach for studying the catalytic thermodynamics of cuboctahedral nanoclusters, using informational statistical mechanics. The Morse potential determines bond energies between cluster atoms in a coordination type calculation. Applied density functional theory (DFT) calculations demonstrate adatom effects on the thermodynamic quantities, which are derived from a Hami...

Development of effective measures for the complexity of human–computer interface design based on a proper model is desirable in order to improve the human performance and to facilitate the system development. In this paper, the authors propose the task-to-action (TTA) model which can describe the task-performing procedure of human operators. Quantitative interface design complexity measures usi...
