Through site-specific amino acid residues, proteins engage with ligands, and uncovering these key residues is critical for deciphering protein function and aiding the development of drugs via virtual screening approaches. Information about ligand-binding residues on proteins is typically scarce, and the process of identifying these residues through wet-lab biological experiments is lengthy and demanding. Consequently, numerous computational strategies have been devised for the purpose of pinpointing the protein-ligand binding residues in recent years. We propose GraphPLBR, a framework built on Graph Convolutional Neural (GCN) networks, for the prediction of protein-ligand binding residues (PLBR). Using 3D protein structure data, residues are modeled as nodes in a graph representation of proteins. As a result, the task of predicting PLBR is restructured as a graph node classification task. Information is drawn from higher-order neighbors using a deep graph convolutional network. Initial residue connections with identity mapping address the over-smoothing issue that arises from the proliferation of graph convolutional layers. To the best of our knowledge, this view represents a more singular and pioneering perspective, leveraging graph node classification for the prediction of protein-ligand binding residues. Our approach consistently surpasses the performance of current leading-edge methodologies across a range of evaluation metrics.

Innumerable patients worldwide are impacted by rare diseases. Although the numbers are smaller, samples of rare diseases are compared to the larger samples of common diseases. The sensitivity of medical information is a significant factor in hospitals' cautious approach to sharing patient data for data fusion. Traditional AI models encounter difficulty in pinpointing rare disease features for disease prediction, a process significantly complicated by these challenges. The Dynamic Federated Meta-Learning (DFML) paradigm, as detailed in this paper, is designed to enhance rare disease prediction capabilities. Dynamically adjusting attention to tasks based on the accuracy of fundamental learners forms the core of our Inaccuracy-Focused Meta-Learning (IFML) method. A supplementary dynamic weighting fusion approach is introduced to improve federated learning's efficacy, where clients are dynamically selected based on the accuracy of each local model. Experiments conducted on two public datasets highlight the superiority of our approach over the original federated meta-learning algorithm, showcasing gains in both accuracy and speed with a mere five training instances. Each hospital's local models are surpassed by 1328% in prediction accuracy by the proposed model.

In this article, a class of constrained distributed fuzzy convex optimization problems is investigated. The objective function in these problems is the sum of a collection of local fuzzy convex objective functions, and the constraints consist of a partial order relation and closed convex set constraints. In an undirected, connected network where nodes communicate, each node possesses only its own objective function and constraints. The local objective functions and partial order relation functions could be nonsmooth. A recurrent neural network approach, underpinned by a differential inclusion framework, is suggested for resolving this problem. The construction of the network model uses a penalty function, thereby removing the requirement for estimating penalty parameters beforehand. By means of theoretical analysis, the state solution of the network is shown to enter and remain within the feasible region in a finite time, eventually achieving consensus at an optimal solution of the distributed fuzzy optimization problem. The stability and global convergence of the network are not predicated on the choice of the starting condition. An illustrative example involving numerical data and an intelligent ship's power optimization problem are provided to exemplify the viability and potency of the suggested approach.

Using hybrid impulsive control, this article analyzes the quasi-synchronization of discrete-time-delayed heterogeneous-coupled neural networks (CNNs). Through the application of an exponential decay function, two distinct non-negative regions, namely time-triggering and event-triggering, are created. Employing a hybrid impulsive control, the location of the Lyapunov functional is dynamically situated across two regions. Saracatinib solubility dmso Situated in the time-triggering region, the presence of the Lyapunov functional prompts the isolated neuron node to release impulses to related nodes in a periodic fashion. The event-triggered mechanism (ETM) is initiated if and only if the trajectory is found within the event-triggering region, and no impulses occur. The hybrid impulsive control algorithm establishes conditions sufficient to ensure quasi-synchronization with a precisely defined error convergence rate. The hybrid impulsive control method, in comparison to pure time-triggered impulsive control (TTIC), offers a significant reduction in impulse count and subsequent communication resource savings without compromising system performance. In conclusion, a practical illustration is provided to validate the proposed methodology.

Oscillatory neurons, the fundamental building blocks of the ONN, a novel neuromorphic architecture, are coupled through synapses. According to the 'let physics compute' paradigm, ONNs' rich dynamics and associative properties facilitate solutions to analog problems. Low-power ONN architectures for edge AI applications, especially for pattern recognition, can benefit from the use of compact VO2-based oscillators. Nevertheless, the question of how ONNs can scale and perform in hardware settings remains largely unanswered. Before deploying ONN, careful consideration must be given to the application's specific demands regarding computation time, energy consumption, performance benchmarks, and accuracy. Circuit-level simulations are used to evaluate the performance of an ONN architecture, built with a VO2 oscillator as a fundamental building block. Our analysis investigates how the number of oscillators impacts the computational resources required by the ONN, including processing time, energy consumption, and memory capacity. Scaling the network reveals a linear increase in ONN energy, positioning it for successful large-scale edge deployment. Furthermore, we investigate the design handles to reduce ONN energy. Computer-aided design (CAD) simulations, underpinned by technological advancements, demonstrate the impact of reducing VO2 device dimensions in a crossbar (CB) configuration, ultimately lowering oscillator voltage and energy usage. ONN architectures are compared against the most advanced designs, showcasing their competitiveness and energy efficiency in scaling VO2 devices oscillating at frequencies exceeding 100 MHz. We present, finally, ONN's proficiency in detecting edges in low-power edge device images, and contrast its results with the corresponding outputs generated by the Sobel and Canny edge detection methods.

Heterogeneous image fusion (HIF) is a method to enhance the discerning information and textural specifics from heterogeneous source images, thereby improving clarity and detail. Despite the proliferation of deep neural network-based HIF methodologies, the most frequently employed data-driven convolutional neural network approach frequently fails to provide a demonstrably optimal and theoretically grounded architecture for the HIF problem, nor does it assure convergence. Microscopes For the HIF problem, this article proposes a deep model-driven neural network. This architecture seamlessly combines the beneficial aspects of model-based techniques, facilitating interpretation, and deep learning strategies, ensuring adaptability. Unlike the general network's black-box nature, the objective function developed here is specifically designed to integrate several domain knowledge modules into the network. This leads to a compact and understandable deep model-driven HIF network, labeled DM-fusion. The feasibility and effectiveness of the proposed deep model-driven neural network are evident in its three constituent parts: the specific HIF model, an iterative parameter learning strategy, and the data-driven network architecture. Furthermore, a loss function method focused on tasks is put forward to achieve the enhancement and preservation of features. Four fusion tasks and their associated downstream applications were used in extensive experiments to assess DM-fusion's performance. The outcomes demonstrate improvements over the state-of-the-art (SOTA) in both fusion quality and operational efficiency. The source code's availability is slated for a forthcoming date.
