We proposed a new way to represent and reconstruct multidimensional MR images. Specifically, a representation capable of disentangling different types of features in high-dimensional images was learned via training an autoencoder with separated sets of latent spaces for image style transfer, e.g., contrast or geometry transfer. A latent diffusion model was introduced to capture the distributions of the disentangled latents for constrained reconstruction. A new formulation was developed to integrate the pre-learned representation with other complementary constraints for reconstruction from sparse data. We demonstrated the ability of our model to disentangle contrast and geometry features in multicontrast MR images, and its effectiveness in accelerated T1 and T2 mapping. © 2024 IEEE.

The paper deals with the analysis of a discrete-time networked competitive bivirus susceptible-infected-susceptible (SIS) model. More specifically, we suppose that virus 1 and virus 2 are circulating in the population and are in competition with each other. We show that the model is strongly monotone, and that, under certain assumptions, it does not admit any periodic orbit. We identify a sufficient condition for exponential convergence to the disease-free equilibrium (DFE). Assuming only virus 1 (resp. virus 2) is alive, we establish a condition for global asymptotic convergence to the single-virus endemic equilibrium of virus 1 (resp. virus 2) - our proof does not rely on the construction of a Lyapunov function. Assuming both virus 1 and virus 2 are alive, we establish a condition which ensures local exponential convergence to the single-virus equilibrium of virus 1 (resp. virus 2). Finally, we provide a sufficient (resp. necessary) condition for the existence of a coexistence equilibrium.

Optical force-induced assembly is a promising yet scarcely explored approach for developing functional tools and objects at the microscale, with a wide range of potential applications. Our previous work was the first to investigate the manipulation of these assemblies in the XY plane. Here, we expand on these techniques by systematically exploring optical trap manipulation with the addition of Z-axis control. Manipulation of the Z-axis is referred to as axial displacement and is a viable approach for actively manipulating the assembly morphology. Experiments are conducted for the first time to explore and detail the response of the assembly during active 3D trap manipulation, informing the development of an autonomous control algorithm over the 2D area of the assembly during motion. This control presents techniques to increase assembly stability or alter the area of the assembly for tasks such as passing through constrictions. This work aims to develop the control techniques required to create a unique micromanufacturing approach inspired by the Kilobot thousand-robot swarm. © 2016 IEEE.

Contact-free manipulation technology represents a novel approach that offers a fresh possibility for human-machine interaction, aiming to meet the evolving demands of this interface. In this paper, we introduce a contact-free planar display control technique based on imaging. In our research, we employ cameras as sensors and integrate infrared lasers with image processing techniques to detect and localize input signals. By establishing a coordinate mapping relationship between the operational plane and the display plane, we achieved contact-free control over the planar display. Our paper introduces two methods for establishing this coordinate mapping. The first involves constructing mapping functions between the rectified and transformed camera imagery and the display plane, thereby creating a point-to-point correspondence. The second method entails dividing both the camera imagery and the display plane into segments, establishing a one-to-one relationship between regions. We analyze the strengths and limitations of these two approaches. While the former boasts higher theoretical precision, it is more susceptible to equipment factors and exhibits slower response speeds. Conversely, the latter, despite its lower theoretical precision, offers faster response times. Through the setup of an experimental platform, we demonstrate the feasibility of our proposed. © 2024 SPIE.

Tractor-trailer wheeled robots (TTWRs) have gained significant attention across various industries and control studies due to their complex dynamics and non-minimum phase behavior, which pose substantial control challenges. This study investigates the control of a differentially-driven tractor to follow a specified path under pure rolling conditions in both forward and backward motion. Notably, it has been established that using static feedback linearization (SFL) leads to instability during backward motion. In contrast, this research uses dynamic feedback linearization (DFL), also known as dynamic extension, for controlling the tractor-trailer system in both directions for the first time. Our findings demonstrate that the internal dynamics of the system remain stable in both forward and backward motions, enabling successful adherence to the desired path. © 2024 IEEE.

The cumulative effects of deuteration on the device lifetime of blue OLEDs with emitters based on common polycyclic aromatic hydrocarbons were studied using two anthracene-based host materials. Their deuterated analogues with incremental deuterium substitutions exhibited similar EL efficiencies but progressively prolonged device lifetimes as a function of deuteration. © 2023, John Wiley and Sons Inc.

Context-CAM: Context-Level Weight-Based CAM with Sequential Denoising to Generate High-Quality Class Activation Maps

引用

IEEE Transactions on Image Processing 2025年 34卷 3431-3446页

Class activation mapping (CAM) methods have garnered considerable research attention because they can be used to interpret the decision-making of deep convolutional neural network (CNN) models and provide initial masks for weakly supervised semantic segmentation (WSSS) tasks. However, the class activation maps generated by most CAM methods usually have two limitations: 1) a lack of the ability to cover the whole object when using low-level features;and 2) introducing background noise. To mitigate these issues, an innovative Context-level weights-based CAM (Context-CAM) method is proposed, which guarantees: 1) the non-discriminative regions that have similar appearances and are located close to the discriminative regions can also be highlighted by the newly designed Region-Enhanced Mapping (REM) module using context-level weights;and 2) the background noises are gradually eliminated via a newly proposed Semantic-guided Reverse Sequence Fusion (SRSF) strategy that can sequentially denoise and fuse the region-enhanced maps from the last layer to the first layer. Extensive experimental results show that our Context-CAM can generate higher-quality class activation maps than classic and state-of-the-art (SOTA) CAM methods in terms of the Energy-Based Pointing Game (EBPG) score, and the improvements are up to 35.49% when compared to the second-best method. Moreover, for WSSS tasks, our Context-CAM can directly replace the CAM method used in existing WSSS methods without any architectural modification to further improve the segmentation performance. © 1992-2012 IEEE.

A recently proposed kinetic model describing the oxidation and reduction of donor-defects in semiconducting metaloxide thin films has been applied to characterize the properties of the donor-defects in fluorinated indium gallium-zinc oxide. The excellent agreement of the measured data with the modelling curves is a nice demonstration of the utility of the model as a useful tool for characterizing the nature of the donor-defects in metal oxide films. © 2023, John Wiley and Sons Inc.

As water and energy grids are highly interconnected, water-energy nexus (WEN) is considered an attractive target for malicious attackers. Attacking WEN affects both systems simultaneously; consequently, the attack is able to create fatal damage in the entire network. In this paper, we propose to tackle this problem using different deep learning models with different loss functions. Additionally, a mixed-integer nonlinear programming (MINLP) WEN in presence of renewable energy sources model is reformulated into a mixed-integer linear programming model for real-time implementation purposes. The optimization model is developed using MATALB, and the deep-learning models are implemented using Python keras framework.
