Summary: This paper presents a computationally efficient chance-constrained rollover-free motion planning method for reconfigurable vehicles with limited accuracy 3-D terrain models. The method formulates the motion planning problem as a nonlinear optimal control problem, utilizing a constraint on the probability of rollover. By deriving a geometric interpretation of the chance constraint based on SO(3), the computational efficiency is increased. Monte Carlo simulations and experimental data validation demonstrate the usefulness and performance of the proposed method.

Summary: This article proposes a decoupling method that allows for the separation of a second output from a reconfigurable dc battery without affecting the main output. The proposed system provides a nonisolated port for the motor drive inverter(s), while generating an additional isolated output for auxiliary devices. The solution operates with a wide range of voltages and can balance the battery modules during charge/discharge cycles.

Summary: Microrobotic swarms have the potential to perform targeted delivery tasks with adaptability, but applying them in vivo faces the challenge of medical imaging-based localization. This article proposes an optimized actuation strategy to enhance the ultrasound imaging contrast of a reconfigurable colloidal microswarm, which is experimentally validated. Additionally, pattern transformation is used to further enhance the ultrasound contrast and reduce the dosage of nanoparticles.

Summary: Modular cascaded circuits offer improved fault tolerance and flexibility in reconfigurable battery applications, but low-frequency ripple can accelerate battery aging. This paper presents a ripple-oriented high-bandwidth control technique to minimize low-frequency components, improve battery treatment, and reduce losses. The method enhances feedback bandwidth using observers and is applicable to various topologies, reducing battery losses by up to 20% in laboratory testing.

Summary: The paper proposes two architectures for dynamically scalable network-on-chip (NoC) to save power in dynamically reconfigurable intellectual properties (IPs). The first architecture is a run-time scalable column-based NoC, while the second architecture extends to dynamically scale both the rows and columns of the NoC. A robust control manager is developed to optimize reconfiguration costs and control IP and sub-NoC reconfigurations. The implemented prototypes on a Virtex 6 FPGA show significant power reduction compared to traditional static architectures at the same NoC size, indicating the potential usefulness of the scalable NoC in runtime sharing of FPGA resources.

Summary: This letter investigates the optical transmission properties of waveguides covered with thin films. It is found that under certain conditions, a reduction in material loss can lead to an increase in propagation losses in the waveguide. Experimental and numerical simulation results suggest that this nontrivial behavior is due to mode reshaping caused by changes in the absorption coefficient of the covering film. The findings offer new perspectives for engineering complex reconfigurable nonlinear optical responses and transmittance dependences of nanomaterial covered waveguides.

Summary: In this article, an adaptive control framework based on deep reinforcement learning is proposed for dynamically reconfigurable battery systems. The framework uses deep Q-networks to learn the operations of the battery system, reducing the complexity of building experiences or expert models and improving battery operating time through cell balancing. Extensive simulation and experimental studies with real-world data demonstrate the effectiveness and efficiency of the proposed control framework.

Summary: In this work, we present the proof-of-concept design of an ultrathin and thermo-optically reconfigurable silicon metalens. It demonstrates continuous, linear modulation of the focal length and achieves diffraction-limited performance. We propose that combining machine-learning algorithms with further optimization of the meta-atoms can lead to the development of thermally reconfigurable metalenses with improved performance, and this approach could inspire the realization of active metasurfaces with other emerging materials in the field of thermo-nanophotonics.

By evaluating the decellularization quality in real-time, the researchers were able to obtain DNA and sarcomere-free constructs after 72 hours of SDS perfusion-decellularization. Additionally, the passive elasticity measurement can serve as an additional online indicator of decellularization quality.

Summary: Muscle biomechanics is determined by the spacing of individual sarcomeres within muscle fibers. The non-uniform distribution of sarcomere lengths may affect force production and elastic deformation. This study implemented live tracking of sarcomere length distributions and force assessments during axial stretch to analyze the impact of stretch on sarcomere lengths. The results showed a non-uniform distribution of sarcomere lengths and a minor change in distribution upon stretch. Additionally, there was almost no change in sarcomere length variability during elastic deformation. This study provides valuable insights into the contribution of serial elastic and force producing elements in muscle research.
