Quorum sensing (QS) mimickers can be used as an effective tool to disrupt biofilms which consist of communicating bacteria and extracellular polymeric substances (EPS). In this paper, a stochastic biofilm disruption model based on the usage of QS mimickers is proposed. A chemical reaction network (CRN) involving four different states is employed to model the biological processes during the biofilm formation and its disruption via QS mimickers. In addition, a state-based stochastic simulation algorithm is proposed to simulate this CRN. The proposed model is validated by the in vitro experimental results of Pseudomonas aeruginosa biofilm and its disruption by rosmarinic acid as the QS mimicker. Our results show that there is an uncertainty in state transitions due to the effect of the randomness in the CRN. In addition to the QS activation threshold, the presented work demonstrates that there are underlying two more thresholds for the disruption of EPS and bacteria, which provides a realistic modeling for biofilm disruption with QS mimickers. © 2023 IEEE.

Current cloud-based systems face the challenge of managing storage and eliminating redundant data associated with the exponentially growing multimedia content, where numerous semantically similar but nonidentical files are included. In this paper we introduce a novel secure deduplication framework for encrypted cloud storage. This proposed system employs similarity-preserving hashing, fuzzy PoW protocol, and attribute-based encryption to perform efficient deduplication without compromising security and providing ownership verification. Security and deduplication rate scalability are improved over brute-force and ownership-faking attacks by dynamically varying thresholds based on file characteristics. Experimental evaluation shows that a 48% average deduplication rate and resistance to common attack vectors make it suitable for real-world cloud storage scenarios. The framework fills critical gaps in existing approaches and provides an innovative solution for dealing with similarity-aware data deduplication in privacy-sensitive environments. © 2025 IEEE.

Fungal infections at the skin of puppies, including dermatophytosis, are commonplace and pose great health dangers to each the animals and their proprietors. Although these infections do no longer affect human skin immediately, rapid detection remains important for well-timed remedy and spreading prevention. The currently established diagnosis process frequently includes the visual confirmation of the infection by medical professionals and fungal culture and is often referred to as time-intensive and highly dependent on medical professionals’ qualifications. Over the past few years, deep learning has become quite a promising area of research, R&D, and deployment in multiple fields, including medical imaging. The current research develops a deep learning model for fungal infection detection on the skin of dogs based on a variety of architectures and variations of Convolutional Neural Networks to classify image patches as healthy and infected. Transfer learning for the model structuring is reviewed to determine the impact of pre-trained models on the model’s learning efficiency. © 2025 the Author(s).

In sparse-angle X-ray tomography, CT images possess significant noise and artifacts in reconstruction. An important image reconstruction research effort in this area aims to remove these artifacts while preserving image features. Approaches to the problem can be divided into two main categories, post-processing on reconstructed images and pre-processing on the sinogram. Following the rise of deep learning methods, many data-driven models have been proposed in both categories. However, those methods require a large amount of fully sampled data for training. In this paper, inspired by the development of the video frame synthesis technique, we propose an adversarial learning-based spatial transformer network for projection image synthesis, which aims to improve the quality of reconstructed images by reasonably increasing the number of projection images based on the existing projection data. Simulation and experiments have shown that this data-driven model can give rise to competitive results compared with conventional algorithms. © 2024 IEEE.

Wireless Sensor Network (WSN) is a contemporary topic of research that has proven to be an advantageous technology for a wide variety of applications, including those dealing with the environment, the military, and health, as well as uses at home and in the workplace. There are two different kinds of WSNs: mobile WSN and static WSN. Distribution, location, and tracking are three of the many new conceptual and optimization challenges presented by WSNs. These challenges are particularly important given the fact that a great number of applications are dependent on WSNs for information. There are a number of challenges associated with this type of WSN, including high bandwidth requirements, high energy consumption, providing Quality of Service (QoS), data processing, compression, and cross-layer design. Authors of this review have conducted a survey of the relevant literature and draw the conclusion that routing protocols for WSNs make use of a variety of approaches, such as Hierarchical Based Routing Protocols (HBRP) and Location-Based Routing Protocols (LBRP), in order to accomplish their goals. Each of these approaches is capable of meeting the necessary transmission specifications. The fundamental goal of the analysis is to ensure that both power consumption and security are taken into account while conducting the analysis of performance matrices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Currently, the overcrowding of unlicensed spectrum bands is causing severe interference to IoT devices embedded with sensors. CR-IoT networks apply cognitive radio capabilities to the internet of things to solve the spectrum scarcity issue in conventional IoT networks. An CR radio detects available spectrum channels by dynamically modifying its programming and configuration. IoT, smart cities, and 5G all benefit from cognitive radio applications. A cognitive radio application is useful for IoT, smart cities, and 5G. Compared to benchmark Cognitive Radio MAC (CR- MAC) protocols, the proposed protocol is more reliable, intelligent, and smart. CR technology for IoT applications can be advanced by us in order to make IoT more affordable and applicable. It is demonstrated by comparing the proposed RECRIoT-MAC protocol with benchmark CR-MAC protocols that is more energy efficient and consumes less communication time. This paper examines RECRIoT-MAC's energy consumption and throughput. © 2024 IEEE.

The paper aims to establish a robust machine learning approach for accurately categorizing the level of physical activity based on data collected from wearable sensors. Data from more than 10,000 participants was gathered through the utilization of sensors embedded in smartphones and smartwatches. These sensors include accelerometers, gyroscopes, and heart rate monitors. The acquisition of critical attributes, such as heart rate metrics, spectral entropy, and variance, involves meticulous feature engineering and thorough preprocessing. These measures effectively capture the temporal and spectral aspects of physical activity. An ensemble model is constructed using Gradient Boosting Machines (GBM) to achieve precise predictions of activity intensity categories. The GBM model consistently maintains accuracy levels above 99% for all types of physical activity, ranging from moderate to vigorous, sedentary, and mild. In order to ensure the model's robustness and prevent overfitting, hyperparameter optimization is conducted through k-fold cross-validation. The findings demonstrate the impressive precision with which machine learning algorithms classify activities. The implications can have far-reaching effects on the promotion of physical activity and the improvement of health outcomes. © 2024 IEEE.
