Abstract Untethered miniature soft robots have significant application potentials in biomedical and industrial fields due to their space accessibility safe human interaction. However, the lack of selective forceful actuation is still challenging revolutionizing unleashing versatility. Here, we propose a focused ultrasound-controlled phase transition strategy for achieving millimeter-level spatially Newton-level force robots, which harnesses ultrasound-induced heating trigger inside robot,...
Magnetic continuum robots (MCRs), which are free of complicated structural designs for transmission, can be miniaturized and therefore widely used in the medical field. However, deformation shapes different segments, including deflection directions curvatures, difficult to control simultaneously under an external programmable magnetic This is because latest MCRs have with invariable moment combination or profile one more actuating units. Therefore, limited dexterity shape causes existing...
Computing the classical capacity of a noisy quantum channel is crucial for understanding limits communication over channels. However, its evaluation remains challenging due to difficulty computing Holevo and even greater regularization. In this work, we formulate computation as an optimization problem on product manifold constructed from probability distributions their corresponding pure input states channel. A Riemannian gradient descent algorithm proposed solve problem, providing lower...
Coordination geometries of transition metals play vital roles in the self-assembly process supramolecular coordination complexes. Herein, seven-coordinate 3d metal ions were applied as templates and catalytically active sites for subcomponent that resulted a new category covalent metallacycles. Single-crystal structures showed sizes, configurations, functionalization metallacycles could be tuned by selection rigid dihydrazide, ions, prefunctionalized subcomponents, respectively. Moreover,...
This article designs a model-free control scheme based on cerebellum-inspired network model for tracking and visual servoing of surgical rigid-flexible hybrid robotic endoscope. The robot is composed rigid manipulator flexible endoscope as the end-effector. Inspired by cerebellum associated with human motion control, we proposed remote center (RCM) constraints, which does not need to know kinematic robot. combines liquid state machines (LSMs) zeroing neural (ZNN), where LSM able generate...
A unique, rhodium-catalyzed reaction of cyclopropene carboxylic acids with isatins has been developed, which takes place through a trapping process transient cyclic oxonium ylides. This tolerates wide variety and N-protected or unprotected represents new, direct strategy to access valuable γ-substituted γ-butenolide architectures containing an oxindole moiety in very high yields under mild conditions.
A metallacycle-based porous crystal with intrinsic cavities could efficiently steer CO 2 -to-CH 4 electrocatalytic conversion by the synergic effect of size-adaptivity and confined microenvironment.
The mark weighted correlation function (MCF) $W(s,\mu)$ is a computationally efficient statistical measure which can probe clustering information beyond that of the conventional 2-point statistics. In this work, we extend traditional statistics by using powers density field gradient $|\nabla \rho/\rho|^\alpha$ as weight, and use angular dependence scale-averaged MCFs to constrain cosmological parameters. analysis shows based weighting scheme statistically more powerful than scheme, while...
Continuum robots have great application value and broad prospects in various fields due to their dexterity compliance. To fully exploit advantages, it is crucial develop an effective, accurate robust control system for them. However, research on continuum robot still its infancy there are many problems remaining unsolved this field. In particular, paper focuses the task-space behavior generic of heterogeneous robots. First, a controller proposed achieve kinematic motion visual servoing with...
Integrated communication and sensing (ICAS) is an enabling technique of 6G communications, which requires accurate clock synchronization among transceivers. The accuracy conventional time methods in 4G/5G networks usually around 100 ns, sufficient for signal detection, but unsatisfied ICAS-driven applications. In this paper, we aim to provide solution ICAS, challenging due the disturbance random channel fading, multipath interference uncertain UE location parameters. To address challenge,...
In this paper, we report an interesting kinematic phenomenon around the halos' edge related to splashback radius. After shell-crossing, cosmic flow exhibits various rotational morphologies via stream-mixing. Vorticity is generated in a particular way that coincides with large-scale structure. Notably, one specific morphology, which spiraling inward and compressing third direction, concentrates halos. A detailed examination reveals sharp change logarithmic derivative of its volume fraction,...
The tomographic Alcock-Paczynski (AP) method is a promising that uses the redshift evolution of anisotropic clustering in space to calibrate cosmology. It extends applicable range AP substantially nonlinear scales, yielding very tight cosmological constraints. For future stage-IV slitless spectroscopic surveys, non-negligible errors might reduce advantage by suppressing resolution structure along line sight. present work studies how propagate parameters analysis. We use formula $\sigma_z =...
