Communication aspects of virtual learning environments: perspectives of early adopters [PDF]
, 2007 Virtual Learning Environments (VLEs) are increasingly used in higher education to support communication and collaboration among students. However, there is little research into the effectiveness of VLE communication tools, and how they might be improved.

Time scales involved in market emergence
, 2003 In addressing the question of the time scales characteristic for the market formation, we analyze high frequency tick-by-tick data from the NYSE and from the German market. By using returns on various time scales ranging from seconds or minutes up to two

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, EarlyView.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Time networks: history and synchronicity in contemporary Croatian cinema
Images. The International Journal of European Film, Performing Arts and Audiovisual Communication, 2018 The paper demonstrates the prominence of network narratives (films with several autonomous storylines, globally popular since the mid-1990s) in post-Yugoslav, particularly Croatian, cinema, with examples such as Metastases (2009), The Reaper (2014), You Carry Me (2015), The Constitution (2016), The Trampoline (2017), etc.

Advanced Materials, EarlyView.Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...
