Currently available quantum processors are noisy intermediate-scale quantum (NISQ) devices. The variational quantum eigensolver (VQE) is an algorithm that is closer to near-term applicability due to lower quantum hardware requirements. In VQE, trial states with variational parameters are prepared by quantum computers, and the optimal parameters are determined by a classical optimizer. This optimization is known to be an NP-hard problem. In this work, we make a comparison between various gradient-free optimizers in terms of approximation ratio and function evaluations. As a result, we find that COBYLA method is the best to find the approximated solution with a lower number of executions of quantum computers.

Recent progress in design of nanomechanical tools with shape memory effect (SME) resulted in successful realization of the new systems for 3D nanomanipulation and bottom-up nanointegration of the nanoobjects like CNT, nanowires etc. SME demands controlled heating of the active layer of the shape memory nanotool. The heating can lead to thermal drift and errors in positioning of the nanotool. The paper presents the experimental data on the thermal expansion of a new heating system which includes two tungsten needles, numerical modeling and experimental data on the thermal expansion of a heating system with the tungsten microneedle depending on the configuration of its tip geometry. It is proved that the control system for nanomechanical devices including the two microneedles and the microneedle with optimized profile demonstrates both improved precision of positioning (less than 50 nm) and smaller electric energy consumption.

The linear feed system is widely used in the field of micro-nano mechanism and micron-level precision machine tools. In this paper, a simulation method for the thermal characteristics of the linear feed system is proposed, and the influence of its own heat source on the repeatability of positioning is analyzed. The thermal deformation of the screw and guiderail is simulated by using the load method of moving heat. The effect of feed speed and bearing preload on the repeatability of positioning is analyzed by using finite element simulation, which provides information guidance for designers and field engineers to improve the repeatability of positioning.

In this paper, according to the low positioning accuracy of vascular interventional surgery and the large demand of experienced surgeons, we design a macro-micro combined catheter-guided robot to assist catheter intervention. The vascular interventional robot has micro module at the end of the actuator, which is consisted of flexible hinge and parallel double plate mechanism. The micromotion module can help implement micro movement and adjust the displacement offset caused by twisting process of the catheter. Kinematics analysis of the proposed interventional surgical robot was performed, and the work space analysis of the catheter was accomplished using the quintic polynomial method. Finally, to verify the feasibility of the robot, finite element analysis of the terminal micromotion module of the surgical robot was performed. It has been shown that the mechanism of the surgical robot has good statics and kinematics characteristics.

The capability of handling thin semiconductor chips during the pick-and-place process has become one of the major challenges in chip packaging process. When the chip becomes thinner, strength of the chip decreases dramatically and chip cracking increases, especially during the pick-up process. Traditional pin driving systems in the pick-up equipment that based on servo-motor and cam mechanisms are difficult to realize precise control of ejecting velocity and impact forces when peeling chips from the blue tape. The research presented in this paper aims at developing a pin driving system based on piezo-stack actuator and flexure mechanism for thin die pick-up process. First, the concept design of the piezo-driven flexure mechanism for the thin die pick-up process is established by comparison with traditional die pick-up equipment. Then, a bridge type flexure mechanism intended for the thin die pick-up process is designed and analyzed. The structure of the flexure mechanism is optimized through a parametric model using response surface method. A prototype of the mechanism is developed and tested. The experimental results are discussed. The flexure mechanism can finally achieve a displacement amplification over 9.

We consider the mechanical behavior of soft pneumatic network bending actuators (PneuNets) consisting of a series of chambers made of elastomeric material and fixed to an inextensible bottom layer. The pressure-induced bending angle in free space, as well as the contact force between the actuator tip and an external rigid obstacle are modeled with combined analytical-Finite Elements (FE) approach. We propose two distinct mechanisms for free-end bending, namely, bending of the bottom layer, and bending due to the contact forces between inflated membranes of neighboring chambers. It is found that the main contribution to the total free-end bending angle comes from bending of the inextensible layer, as opposed to bending entirely due to membrane-membrane interactions. It is also found that the pressure-induced contact force between the actuator tip and an obstacle is solely due to the membrane force of the chamber at the actuator's free end and the related moments. The model predictions are compared to FE simulations and experimental data obtained from testing of an in-house fabricated prototype.

All samples can be characterized as hexagonal apatite structure with good single-phase property. The relative densities of ceramic pellets increase gradually with the increase of La/Si ratio. The surface SEM images of the sample with $mathrm{x}=1.67$ shows relatively dense microstructure. The oxygen ion conductivities of ceramic pellets increase gradually with the increase of La/Si ratio, which could be ascribed by both relative density and interstitial oxide ion concentration. The sample 1450-1.67LSO has high oxide ion $sigma_{text{tot}}$ of $6.62 times 10^{-4}mathrm{S} text{cm}^{-1}$ at 600°C. The results of this study may contribute to optimize the electrical conductivity and density of apatite lanthanum silicate electrolyte by modulating La/Si ratio.

Designing a filter membrane that can separate Na+ and K+ ions is of great significance for the study of biomimetic ion channels. Using nonequilibrium molecular dynamics simulations, we investigated monolayer and quadrilayer graphene-embedded 18-crown-6 ether nanopores under different external voltages in solution. We showed that the crown ether nanopores exhibit Na+ ion selectivity at low electric field but turn to K+ ion selectivity at high electric field. Ion translocation time of K+ ions is longer than that of Na+ ions in the monolayer crown ether nanopore, while in the quadrilayer crown ether nanopore, ion translocation time of K+ ions is shorter than that of Na+ ions. We demonstrated a synergetic mechanism for ion transport through the filter membrane from two perspectives: free energy through the nanopore and peeling of ion hydration layer. Partially dehydrated ions pass through the nanopore in a ‘knock-on’ manner due to electrostatic repulsion. Our work highlights the application of crown ether nanopores in the field of artificial biomimetic ion channels and ion filtration.

Ising spin computing has received gaining attention as an efficient computing technology for solving combinatorial optimization problems. We have introduced extraction-type majority voting logic (E-MVL) that purposely disconnects the interactions between spins and controls the sparsity to find the ground state. In this study, we examine how to control the sparsity, which is a key factor in performance. As a result, the residual energy of E-MVL is reduced by 33.2% compared with that of highly optimized simulated annealing (SA) at solving the Sherrington-Kirkpatrick model with 400 spins. Further, we show that E-MVL exhibits acceleration by increasing the sparsity. These results indicate that E-MVL provides faster and more accurate optimizations than SA by setting an appropriate sparsity.
