TL;DR: Catala: El treball es una exploracio del canal de difusio molecular per nanoredes moleculars, en el qual s'identifica la resposta impulsional i en frequencia del canal, es comprova la seva linealitat i invariancia i s'extreuen les principals caracteristiques de comunicacio.

TL;DR: The plasmodium of Physarum polycephalum, a unicellular and multinuclear giant amoeba that shows adaptive behaviors, seemed to acquire a reversed thermotactic property, a new preference for the lower temperature.

TL;DR: This paper provides two design aspects of neuron networks, which includes the design of an interface between nanodevice and neurons that can initiate signaling, and theDesign of transmission scheduling to ensure that signals initiated by multiple devices will successfully reach the receiver with minimum interference.

TL;DR: This work proposes Quorum Sensing as a novel way to achieve synchronization between nodes of a nanonetwork, a mechanism used by bacteria to sense their own population and coordinate their actions, through the emission and sensing of molecules called autoinducers.

TL;DR: Two approaches to form an in vitro microtubule network in a self-organizing manner are proposed and observed that a few sender and receiver nanomachines were interconnected with the first approach, and that distinct topologies of microtubules were reorganized with the second approach.

TL;DR: In this article, the authors present both simulated and partial empirical evidences for the computational utility of many connected vesicle analogues of an encapsulated nonlinear chemical processing medium.

TL;DR: In the proposed system, a transmitter addresses receivers by location and the address of a receiver is the set of distances to molecular beacons at the location of the receiver.

TL;DR: A stochastic model for molecular communication, which accounts for particle dynamics and noise, is presented, which is applied to the study of flow-based and diffusion-based molecular communication.

TL;DR: A preliminary step is modeling all the phases of the communication among neurons through a block scheme where input/output relationships at each block are characterized in terms of transfer functions, gain and delay.

TL;DR: A computationally efficient transport model is presented, which could be employed to design active transport molecular communication systems, particularly to optimize the shape of the transmission zone.

TL;DR: In order to guide the frantic search for high-conductivity films of nanotube networks, this work turns to the microscopic scale where it is developed a computationally efficient way for calculating the ballistic transport across these networks.

TL;DR: Theoretical examination of the topology-dependent efficiency of optical excitation transfer is theoretically examined, which clearly exhibits autonomous, energy-efficient networking behavior occurring at the nanometer scale.

TL;DR: This work proposes a synthetic gene network for operation in a nanofabricated cell mimic array that propagates a biomolecular signal over long distances using the phenomenon of stochastic resonance and presents a model system that exemplifies the synergism between these realms of research.

TL;DR: This paper presents an alternative method to gather energy from a wide frequency range based on the exploitation of nonlinear dynamics to enhance power production with respect to traditional linear kinetic harvesters.

TL;DR: A methodology to simulate SN PA systems using a Petri net tool called Pnet Lab provides a promising way to represent typical working processes of these systems because of its parallel execution semantics and appropriateness.

TL;DR: Theoretical calculations and FEM simulations have been performed and the possibility of using these kinds of devices to scavenge energy from sonic and ultrasonic waves is shown.

TL;DR: An assessment of the effects of congestion in nanonetworks through consideration of competition among bacteria for conjugation at a nanogateway through considered the effects on performance of traffic generation intensity, source–destination separation distance, propagation time variability, packet lifetime, and the number of bacteria that can be processed concurrently at the nanogates.

TL;DR: In this article, the authors investigated whether the topology of a particular type of biological network, ametabolicnetwork, is related to its robustness. And they found that a small number of metrics correlate with growth and only one of the network representations stands out in terms of correlated metrics.

TL;DR: An important result is proved that the ambiguity problem of insertion–deletion systems is undecidable and six levels of ambiguity are defined based on the components used in the derivation such as axiom, contexts and strings.

TL;DR: The results showed that a greater ECM degradation coefficient was needed for optimal cell migration to occur for the local process and that cell-ECM tractions were larger and would also be of use for research on wound healing, cancer cell invasion, and tissue engineering.

TL;DR: An overview over the past years of research on nanotube-vesicle networks is given, which introduces briefly fundamental physical and chemical principles, basic and sophisticated experimental techniques of network generation and manipulation, and shows application examples and modern approaches to nanofluidic networks that constitute potential future research directions.

TL;DR: It is suggested that adaptive traits of the Chemoton be used as guidelines for the design of an adaptive cell within a modular man-made system and a basic circuitry in silicon is proposed and argued in favour of such implementation of the proposed adaptive cell.

TL;DR: The opportunities and challenges of coupling biomolecule-based information processing systems to nanopore devices are presented and recent developments in terms of nanopore membrane fabrication, surface functionalisation and sensing are presented.
