Site-specific amino acid residues in proteins are responsible for protein-ligand interactions, and recognizing these crucial residues is essential for interpreting protein function and supporting the creation of drugs based on virtual screenings. Generally, the locations of protein ligand-binding residues remain largely undefined, and the experimental identification of these binding sites through biological assays is a lengthy process. Consequently, a significant number of computational methods have been formulated for the task of identifying the protein-ligand binding residues during recent years. GraphPLBR, a framework using Graph Convolutional Neural (GCN) networks, is designed to predict protein-ligand binding residues (PLBR). Graph representations of proteins, derived from 3D protein structure data, use residues as nodes. This method translates the PLBR prediction task into a graph node classification problem. Higher-order neighbor information is extracted using a deep graph convolutional network, while an initial residue connection with identity mapping is employed to mitigate the over-smoothing issue stemming from the increasing number of graph convolutional layers. To the best of our understanding, a novel and groundbreaking viewpoint is presented here, employing graph node classification to forecast protein-ligand binding residues. Our approach, when compared to contemporary state-of-the-art methods, shows superior results concerning several performance indices.

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 struggle to discern and extract the critical characteristics of rare diseases for accurate disease prediction, which is worsened by these challenges. Employing a Dynamic Federated Meta-Learning (DFML) methodology, this paper seeks to improve rare disease prediction accuracy. Our Inaccuracy-Focused Meta-Learning (IFML) method dynamically modifies attention allocation across various tasks, guided by the precision of individual base learners. A dynamic weighting fusion technique is introduced to further refine federated learning; the approach dynamically selects clients based on the accuracy metrics of their respective local models. 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. The proposed model demonstrates a substantial 1328% elevation in predictive accuracy, outperforming the local models specific to each hospital.

A class of constrained distributed fuzzy convex optimization problems, characterized by a sum of local fuzzy convex objectives and partial order and closed convex set constraints, is investigated in this article. Undirected and connected communication networks have nodes where each knows only its own objective function and its limitations. The local objective function and the partial order relation functions may be nonsmooth. This problem's resolution is facilitated by a recurrent neural network, its design based on a differential inclusion framework. Leveraging a penalty function, the network model is developed, eliminating the task of pre-calculating penalty parameters. Through rigorous theoretical analysis, it is established that the network's state solution enters the feasible region in a finite time, remains confined to it, and ultimately converges to the optimal solution of the distributed fuzzy optimization problem. Ultimately, the network's stability and global convergence are invariant with respect to the selected initial state. An intelligent ship's power optimization problem and a numerical example are provided to showcase the feasibility and efficacy of the presented approach.

This paper investigates quasi-synchronization in discrete-time-delayed heterogeneous-coupled neural networks (CNNs) through the application of hybrid impulsive control mechanisms. By incorporating an exponential decay function, two non-negative zones are established and labeled as time-triggering and event-triggering, correspondingly. Two regions define the dynamic location of the Lyapunov functional, which models the hybrid impulsive control. Medicated assisted treatment When the Lyapunov functional occupies the time-triggering zone, the isolated neuron node releases impulses to the corresponding nodes in a repeating, temporal sequence. 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 furnishes sufficient conditions for achieving quasi-synchronization, featuring a predictable and definite error convergence rate. While employing a pure time-triggered impulsive control (TTIC) approach, the proposed hybrid impulsive control method significantly reduces the frequency of impulses, thereby conserving communication resources, while upholding overall performance metrics. Ultimately, a demonstrative instance is presented to confirm the effectiveness of the suggested technique.

A novel neuromorphic system, the Oscillatory Neural Network (ONN), is comprised of oscillators, performing the function of neurons, connected via synaptic links. Problems in the analog domain are addressable using ONNs' rich dynamics and associative properties, consistent with the 'let physics compute' paradigm. Low-power ONN architectures for edge AI applications, especially for pattern recognition, can benefit from the use of compact VO2-based oscillators. However, the extent to which ONNs can scale and the efficiency they achieve when implemented in hardware is currently not well understood. To ensure effective ONN deployment, a comprehensive evaluation of computational time, energy expenditure, performance metrics, and accuracy is essential for a specific application. An ONN is constructed with a VO2 oscillator as its base element, and circuit-level simulations are carried out to measure its architectural performance. A key aspect of our investigation is the relationship between the number of oscillators and the ONN's computational demands, including time, energy, and memory. A notable linear increase in ONN energy is observed as the network expands, aligning it favorably for considerable edge deployments. Moreover, we examine the design parameters for reducing ONN energy consumption. Computer-aided design (CAD) simulations utilizing advanced technology reveal the consequences of shrinking VO2 device dimensions in crossbar (CB) geometry, leading to decreased oscillator voltage and energy consumption. We compare the ONN model with leading architectures, and observe that ONNs are a competitive energy-saving solution for VO2 devices that oscillate at frequencies above 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.

Enhancement of discriminative information and textural subtleties in heterogeneous source images is facilitated by the heterogeneous image fusion (HIF) technique. Deep neural network-based HIF methods have been proposed in abundance, but the widely adopted data-driven convolutional neural network approach typically lacks a guaranteed optimal theoretical architecture and does not ensure convergence for the HIF problem. Itacnosertib price A deep model-driven neural network for the HIF problem is presented in this article, combining the advantages of model-based techniques for interpretability with the capabilities of deep learning approaches for broader applicability. Instead of treating the general network architecture as a black box, the objective function is designed to interact with specialized domain knowledge network modules. This results in the construction of a compact and understandable deep model-driven HIF network, designated as DM-fusion. Three pivotal elements—the specific HIF model, an iterative parameter learning method, and a data-driven network architecture—demonstrate the practicality and effectiveness of the proposed deep model-driven neural network. Additionally, a strategy utilizing a task-driven loss function is introduced to improve and maintain 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. In the near future, the source code will be accessible.
