Room temperature texturing of austenite/ferrite steel by electropulsing


Alireza Rahnama, Rongshan Qin


The work reports an experimental observation on crystal rotation in a duplex (austenite + ferrite) steel induced by the electropulsing treatment at ambient temperature, while the …


Photocatalytic TMO-NMs adsorbent: Temperature-Time dependent Safranine degradation, sorption study validated under optimized effective equilibrium models parameter with standardized statistical analysis


Rizwan Wahab, Farheen Khan, Nagendra Kumar Kaushik et al.


In this paper, chemically synthesized copper oxide nanoparticles (CuO-NPs), were employed for two processes: one is photocatalytic degradation and second one adsorption for the …


Strain Dependent Electronic Structure and Band Offset Tuning at Heterointerfaces of ASnO3 (A=Ca, Sr, and Ba) and SrTiO3


John D. Baniecki, Takashi Yamazaki, Dan Ricinschi et al.


The valence band (VB) electronic structure and VB alignments at heterointerfaces of strained epitaxial stannate ASnO3 (A=Ca, Sr, and Ba) thin films are characterized using in situ


How Native and Alien Metal Cations Bind ATP: Implications for Lithium as a Therapeutic Agent


Todor Dudev, Cédric Grauffel, Carmay Lim


Adenosine triphosphate (ATP), the major energy currency of the cell, exists in solution mostly as ATP-Mg. Recent experiments suggest that Mg2+ interacts with the highly charged …


Humans expect generosity


Pablo Brañas-Garza, Ismael Rodríguez-Lara, Angel Sánchez


Mechanisms supporting human ultra-cooperativeness are very much subject to debate. One psychological feature likely to be relevant is the formation of expectations, particularly …


Visual information and expert’s idea in Hurst index estimation of the fractional Brownian motion using a diffusion type approximation


Ali R. Taheriyoun, Meisam Moghimbeygi


An approximation of the fractional Brownian motion based on the Ornstein-Uhlenbeck process is used to obtain an asymptotic likelihood function. Two estimators of the Hurst index …


Co-operation, Competition and Crowding: A Discrete Framework Linking Allee Kinetics, Nonlinear Diffusion, Shocks and Sharp-Fronted Travelling Waves


Stuart T. Johnston, Ruth E. Baker, D. L. Sean McElwain et al.


Invasion processes are ubiquitous throughout cell biology and ecology. During invasion, individuals can become isolated from the bulk population and behave differently. We …
