Martin, Steven Randolph, Aurelien Botman et al.     Recent advances in focused ion beam technology have enabled high-resolution, maskless nanofabrication using light ions. Studies with light ions to date have, however, focused on …             Controllable magnetic correlation between two impurities by spin-orbit coupling in graphene ▶     F. M. Hu, Liangzhi Kou, Thomas Frauenheim     Two magnetic impurities on the edge of a zigzag graphene nanoribbon strongly interact with each other via indirect coupling, which can be mediated by conducting carriers. By …             Simple scheme for encoding and decoding a qubit in unknown state for various topological codes ▶     Justyna Łodyga, Paweł Mazurek, Andrzej Grudka et al.     We present a scheme for encoding and decoding an unknown state for CSS codes, based on syndrome measurements. We illustrate our method by means of Kitaev toric code, …             Photothermal cellular stimulation in functional bio-polymer interfaces ▶     Nicola Martino, Paul Feyen, Matteo Porro et al.     Hybrid interfaces between organic semiconductors and living tissues represent a new tool for in-vitro and in-vivo applications, bearing a huge potential, from basic researches to …             How mobile are protons in the structure of dental glass ionomer cements? ▶     Ana R. Benetti, Johan Jacobsen, Benedict Lehnhoff et al.     The development of dental materials with improved properties and increased longevity can save costs and minimize discomfort for patients. Due to their good biocompatibility, …             Voluntary rewards mediate the evolution of pool punishment for maintaining public goods in large populations ▶     Tatsuya Sasaki, Satoshi Uchida, Xiaojie Chen     Punishment is a popular tool when governing commons in situations where free riders would otherwise take over. It is well known that sanctioning systems, such as the police and …             Bioinspired Tuning of Hydrogel Permeability-Rigidity Dependency for 3D Cell Culture ▶     Min Kyung Lee, Max H. Rich, Kwanghyun Baek et al.     Hydrogels are being extensively used for three-dimensional immobilization and culture of cells in fundamental biological studies, biochemical processes, and clinical treatments. …                 Don't let your data go to waste...
