Today the world is overwhelmed by a load of different wireless communication technologies. The concept of interconnecting the things around us into a network raises the question about which communication technologies to use for a specific domain. This paper gives an overview over common wireless communication technologies and how to use them to connect smart objects in different application dom...

We present Tiles Cards, a tool to foster end-user design thinking of smart object applications. Tiles Cards facilitate participatory design by abstracting the complexity of IoT technology into a set of interaction primitives and composition rules accessible to nonexperts. Further, it promotes creative thinking by means of a mission-based game in which teams have to fulfill design tasks under co...

The purification of coated vesicles and the discovery of clathrin by Barbara Pearse in 1975 was a landmark in cell biology. Over the past 40 years, work from many labs has uncovered the molecular details of clathrin and its associated proteins, including how they assemble into a coated vesicle and how they select cargo. Unexpected connections have been found with signalling, development, neuron...

We reported a new effective approach to carry out two-photon excitation stimulated emission depletion (2PE-STED) microscopy using a single Ti:sapphire laser system. With an acoustic-optic Bragg cell, the modulated-CW 2PE STED microscope had the benefits of both CW and pulse approaches: lower input power, simple optical scheme and no complicated synchronization. Additionally, it also took advant...

The GTPase dynamin has captivated researchers for over two decades, even managing to establish its own research field. Dynamin's allure is partly due to its unusual biochemical properties as well as its essential role in multiple cellular processes, which include the regulation of clathrin-mediated endocytosis and of actin cytoskeleton. On the basis of the classic model, dynamin oligomerization...

Endocytosis occurs in plants, but the involvement of clathrin-coated vesicles has been unclear; a new study provides strong evidence that, as in animal cells, clathrin-coated vesicles are a major means of internalisation by plant cells.

The encapsulation of objects with protective layers is employed in anticorrosive coatings of the metals [1], conformal coatings in microelectronics [2], micro encapsulation of chemicals for drug delivery [3] and etc. In many research and histological practices the microscopy access to the coated sample is desirable. We report here on facile methodology for immobilization and encapsulation of ob...

background: ultrasmallsuperparamagnetic iron oxide (uspio) nanoparticles are used as blood pool contrast agent for magnetic resonance angiography and perfusion imaging. our aim in this study was to investigate the effect of the two coating types of iron oxide nanoparticles on the relationship between nanoparticles concentration and signal intensity (si) in t1-weighted mr images.   methods : dif...

Transformation thermodynamics, as one of the important branches among the extensions of transformation optics, has attracted plentiful attentions and interests recently. The result of transformation thermodynamics, or called as "thermal cloak", can realize isothermal region and hide objects from heat. In this paper, we presented the concept of "reverse thermal cloak" to correspond to the therma...

Collective motion is a fascinating example of coordinated behavior of self-propelled objects, which is often associated with the formation of large scale patterns. Nowadays, in vitro gliding assay is being considered a model system to experimentally investigate various aspects of group behavior and pattern formation by self-propelled objects. In this work, we have demonstrated the collective mo...
