Numerous methods have been developed for inferring gene regulatory networks from expression data, however, both their absolute and comparative performance remain poorly understood. In this paper, we introduce a framework critical assessment of network inference. We present an in silico benchmark suite that provided as blinded, community-wide challenge within the context DREAM (Dialogue on Reverse Engineering Assessment Methods) project. assess 29 gene-network-inference methods, which applied...
A highly versatile soft gripper that can handle an unprecedented range of object types is developed based on a new design dielectric elastomer actuators employing interdigitated electrode geometry, simultaneously maximizing both electroadhesion and electrostatic actuation while incorporating self-sensing. The multifunctionality the actuator leads to integrated, lightweight, fast, with simplified structure control. As service our authors readers, this journal provides supporting information...

Reverse engineering methods are typically first tested on simulated data from in silico networks, for systematic and efficient performance assessment, before an application to real biological networks. In this paper, we present a method generating biologically plausible which allow realistic assessment of network inference algorithms. Instead using random graph models, known only partly capture the structural properties generate structures by extracting modules interaction Using yeast...

Swarm robotics systems are characterized by decentralized control, limited communication between robots, use of local information, and emergence global behavior. Such have shown their potential for flexibility robustness [1]-[3]. However, existing swarm large still to displaying simple proof-of-concept behaviors under laboratory conditions. It is our contention that one the factors holding back research almost universal insistence on homogeneous system components. We believe designers must...
In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens but significantly larger fields of view with negligible distortion and spherical aberration, as well high temporal in a tiny package. Compound eyes are ideally suited for fast panoramic motion perception. Engineering miniature artificial eye challenging because it requires accurate alignment photoreceptive optical components on curved surface. Here, we describe unique design...

Abstract In minimally invasive surgery, such as cardiac ablation, magnetically steered catheters made of variable‐stiffness materials can enable higher dexterity and force application to human tissue. However, the long transition time between soft rigid states leads a significant increase in procedure duration.
