Earlier studies have suggested abnormal brain volumes in autism, but inconsistencies exist. Using voxel-based morphometry, we compared global and regional 17 high-functioning autistic children with 15 matched controls. We identified significant reduction left white matter volume white/gray ratio autism. Regional reductions were detected for right anterior cingulate, superior parietal lobule volumes, parahippocampal gyrus gray volume, whereas enlargements bilateral supramarginal gyrus,...
Recent years have witnessed significant progress in developing effective training and fast sampling techniques for diffusion models. A remarkable advancement is the use of stochastic differential equations (SDEs) their marginal-preserving ordinary (ODEs) to describe data perturbation generative modeling a unified framework. In this paper, we carefully inspect ODE-based popular variance-exploding SDE reveal several intriguing structures its dynamics. We discover that distribution noise are...
Purpose The aim of this study was to develop a robust post-processing workflow for motion-corrupted datasets in diffusion kurtosis imaging (DKI). Materials and methods proposed consisted brain extraction, rigid registration, distortion correction, artifacts rejection, spatial smoothing tensor estimation. Rigid registration utilized correct misalignments. Motion were rejected by using local Pearson correlation coefficient (LPCC). performance LPCC characterizing relative differences between...

We present a beam homogenizer utilizing on random metalens array (RMA) for enhanced shaping. The RMA, comprising 28 × individual metalenses with sizes, is designed using an improved Gerchberg-Saxton algorithm. As laser traverses the it divided into beams, each exhibiting unique speckle pattern. These beams overlap in far field, significantly enhancing uniformity. RMA demonstrates adaptability to various incident light modes and misalignment variations. numerical simulations indicate over 90%...
Further power scaling and stable laser performance were demonstrated in the Yb/Ce codoped aluminosilicate fiber fabricated through low-temperature chelate gas phase deposition technique. The molar ratio of Ce/Yb was designed optimized to be 0.58 for low background loss, effective photodarkening suppression, no additional thermal load. loss this active 4.7 dB/km its at equilibrium as 3.9 dB/m 633 nm. Benefiting from technique, showed uniform core composition devoid clustering central `dip'...
Phase imaging always deals with the problem of phase invisibility when capturing objects existing light sensors. However, there is a demand for multiplane full intensity measurements and iterative propagation process or reliance on reference in most conventional approaches. In this paper, we present an end-to-end compressible method based deep neural networks, which can implement estimation using only binary measurements. A thin diffuser as preprocessor placed front image sensor to...
Improving running-in quality is an important project of Green Tribology. In actual environment, the mechanical equipment greatly affected by system parameters. view this, experiments were performed at different rotating speeds on a pin-on-disc tribometer. Chaos theory was used to investigate effect quality. The experimental results showed that could be better evaluated using chaotic characteristic parameter “Convergence (CON)”. greater CON, With increase speed, CON first gradually increased...

The presented results, exploring influences activated regions, indicated mapping combined with spectral matrix factorization principal component...
A new method of transmission efficiency and uniformity measurement for optical fiber image component(OFITC) in visible band is proposed. The ray which emitted from the light source received by a brightness sensor chip, can convert rough into visual specific area weighted calculation. matrices designated before after placing OFITC are named S1 S2, respectively. After filtering, quotient average values S2. In order to calculate uniformity, S2 divided four parts circles or rings. variances...
Sampling from diffusion models can be treated as solving the corresponding ordinary differential equations (ODEs), with aim of obtaining an accurate solution few number function evaluations (NFE) possible. Recently, various fast samplers utilizing higher-order ODE solvers have emerged and achieved better performance than initial first-order one. However, these numerical methods inherently result in certain approximation errors, which significantly degrades sample quality extremely small NFE...
