Detecting phase transitions in collective behavior using manifold's curvature by Kelum Gajamannage, Erik M. Bollt

“…Here, we propose a method of detecting phase transitions and splitting the manifold into phase transitions free sub-manifolds. Therein, we firstly utilize a relationship between curvature and singular value ratio of points sampled in a curve, and then extend the assertion into higher-dimensions using the shape operator. …”

Forêt et conservation des dunes littorales : le cas exemplaire de la Réserve biologique domaniale de la Côte d'Opale (Pas-de-Calais) by Yves Petit-Berghem

“…The coastal dunes of the Pas-de-Calais area (dunes of Berck-Merlimont with the « Réserve biologique domaniale de la Côte d’Opale », northwest France) is one of the few dune systems in France characterized by the free expression of dynamic processes. The mobility of the site ensures the renewal and diversity of dune environments and thus habitats and species associated with them. …”

Technological a priori and Communicative Action in Kurt Vonnegut’s Player Piano by Mete Han Arıtürk, Mehmet Büyüktuncay

“…This study scrutinizes how the technocratic state in Vonnegut’s novel utilizes technology to pacify and disempower the masses, challenging the notion that technology is merely a value-free accumulation of know-how. The devalued human subject and dehumanized society depicted in Vonnegut's anti-utopian narrative are discussed with reference to Marcuse’s notion of 'one-dimensional society' and Habermas’s theory of 'communicative action' to provide the critical framework for the analysis of the impoverishing and colonizing effects of technological rationality on the lifeworld.…”

Acoustical Behaviour of Sodium Nitroprusside in Aquo-Organic Solvent Media at 308.15 K by Monalisa Das, Smrutiprava Das, A. K. Pattanaik

“…A quantitative relationship has been established among the acoustical properties like ultrasonic velocity (U), adiabatic compressibility (β), intermolecular free length (Lf), acoustic impedance (Z), apparent molar compressibility (Kϕ), apparent molar volume (Vϕ), limiting apparent molar compressibility (Kϕ0) limiting apparent molar volume (Vϕ0), and their constants (SK, Sv). …”

Fixed-Time Trajectory Tracking Control of Autonomous Surface Vehicle with Model Uncertainties and Disturbances by Jiawen Cui, Haibin Sun

“…By combining the FTDO and ISMC techniques, a new control scheme (FTDO-ISMC) is developed, which can achieve both disturbance compensation and chattering-free condition. (3) Aiming at reconstructing the unknown nonlinear dynamics and external disturbances, a fixed-time unknown observer (FTUO) is proposed, thus providing the FTUO-ISMC scheme that finally achieves trajectory tracking of ASVs with unknown parameters. …”

A Mathematical Model of the Transmission Dynamics and Control of Bovine Brucellosis in Cattle by Stephen Abagna, Baba Seidu, C. S. Bornaa

“…In this work, a deterministic model is developed to investigate the transmission dynamics and control of bovine brucellosis in a herd of cattle. The disease-free equilibrium point of the model is shown to be locally asymptotically stable whenever basic reproduction number R0≤1 and unstable if R0>1. …”

A Novel Adaptive Probabilistic Nonlinear Denoising Approach for Enhancing PET Data Sinogram by Musa Alrefaya, Hichem Sahli

“…We show that the Chi-square is the appropriate prior for finding the edge probability in the sinogram noise-free gradient. Since the sinogram noise is uncorrelated and follows a Poisson distribution, we then propose an adaptive probabilistic diffusivity function where the edge probability is computed at each pixel. …”
