The multi-class classification of images is a pivotal challenge within the realm of image processing. As the volume of visual data continues to expand, there is a burgeoning interest in harnessing the unique capabilities of quantum computation to augment the efficiency of classification tasks. However, many existing methods for training quantum image multi-classifiers parallel classical machine learning techniques, where the requisite circuit measurements increase linearly with the volume of training data. This work introduces a novel approach for training a quantum image multi-classifier based on the quantum search algorithm. We have meticulously conducted rigorous experiments on a handwritten digit dataset, a classic benchmark in the field. The results have been meticulously compared with previous works, and the comparative analysis not only validates the efficiency of our proposed approach, requiring only O(N/b) measurements during training, but also highlights a significant quadratic speedup of the algorithm.

Dear Editor,This letter is concerned with stability analysis and stabilization design for sampled-data based load frequency control(LFC) systems via a data-driven method. By describing the dynamic behavior of LFC systems based on a data-based representation, a stability criterion is derived to obtain the admissible maximum sampling interval(MSI) for a given controller and a design condition of the PI-type controller is further developed to meet the required MSI. Finally, the effectiveness of the proposed methods is verified by a case study.

We numerically study the optical bistability (OBIS) in periodic multilayers of Ag/SiO_(2).The calculated dependence of the output on the input intensity shows two possible OBIS states at the test *** is due to the field localization effects in silver layers with nonlinear refractive index modifying resonant tunneling of electromagnetic waves;the other,with about a three times lower threshold input intensity,is attributed to the intensity dependence change of the Ag/SiO_(2) composite's effective dielectric constant from metallic-like (negative) to dielectric-like (positive).With appropriate design engineering the Ag/SiO2 multilayers could find broad applications in all-optical information processes.

An analytical model for calculating the propagation time of shock wave in a wave shaper is presented in this study. The calculated results show that the contours of three typical detonation waves, such as conical detonation wave, spherical detonation wave, and planar detonation wave, can be formed in the main charge by changing the thickness of wave *** results show that the planar detonation wave do better than the conical detonation and the spherical detonation wave in increasing the length–diameter ratio of explosively-formed projectiles(EFP) and keep the nose of EFP integrated. The detonation wave can increase the length–diameter ratio of EFP when the wave shaper has the suitable thickness.

In the present investigation, influence of gaps between multiple floating structures on wave forces is examined. Strong and complicate hydrodynamic interactions between the floating bodies are observed and the numerical computations have proved the existence of the sharp peak force response on each floating body at some special resonant wave numbers. The resonant wave number is also proved to be around kL=nπ(n=1, 2, …, ∞) with a corresponding frequency shift. A small yet finite gap width will also give influence on the resonant frequency and resonant amplitude of the wave forces, but when the distance between two aligned box-shaped floating bodies becomes big enough, the hydrodynamic interaction can be neglected. The strong hydrodynamic interaction feature has its own important practical significance for the design of module structures and the links (connection) in the whole floating body system. Moreover, the importance is closely related to the hydro-elasticity analyses of a multiple box-shaped floating body system, in which local loads may be as important as the integrated loads.

Theoretical analysis shows that the deviation roughness w and the lateral correlation length ζ of a weak scattering object determine the different properties of the contrast of the speckles in the image plane of a 4f system. Experimentally, we have measured the data of the speckle contrast versus the radius R of the variable filtering aperture. By fitting the theoretical results to these data, we extract the parameters w and ζ of the random surfaces with Gaussian correlation. This method can determine the two parameters simultaneously and independently, and pre-calibrations are not needed

Objective: To evaluate the characteristics of Bletilla striata microspheres(BSMs) and its effects as an embolic agent in a rabbit model. Methods: BSMs were prepared with an emulsi?cation-cool condensation-chemical cross-linking method. The characteristics of BSMs in vitro were observed. Embolization experiments were performed in renal artery of rabbit and in a rabbit liver VX2 carcinoma model. Seventy-two New Zealand rabbits were divided into 2 groups, and the right renal artery was embolized with BSMs(200 μm in diameter) in the experimental group and with polyvinyl alcohol(PVA) of the same size in the control group. The pathological findings were examined with hematoxylin-eosin and Masson stainings. Liver and renal functions were tested before and after ***2 tumor was transplanted in 15 New Zealand rabbits, which were randomly divided into 3 groups(n=5). Group A were treated with saline, group B with a mixture of doxorubicin and lipiodol, and group C with hepatic arterial infusion of BSMs(200 μm in diameter). Tumor growth rate was evaluated by magnetic resonance imaging ***-related factors(bax, bcl-2) and tumor vascular endothelial cell growth factor(VEGF) were evaluated through immunohistochemical staining. Results: The characteristics of BSMs in vitro were in full compliance with the requirements for use in interventional procedures. In the renal artery embolization experiment, after BSMs intervention, it was more dif?cult to form collateral circulation than that with PVAs, and the kidney manifested atrophy and calci?cation. There were no signi?cant difference of liver and renal functions in rabbits between groups. In the liver VX2 carcinoma embolization experiment, compared with group A, the growth rate of VX2 liver tumor and Bcl-2 levels was reduced, while apoptosis index, Bax, and VEGF were increased in group B(P0.05). Conclusions: The characteristics of BSMs in vitro a
