DNA has found applications in a diverse array of fields such as computing, medical diagnosis, and circuits. Designing DNA fragments that meet specific requirements is crucial for ensuring the smooth execution of tasks in these domains. However, the conventional approach of combining constraints with evolutionary algorithms often encounters challenges like orthogonality and thermodynamic instability. This poses risks to the control of reaction processes. To tackle these challenges, we have undertaken two tasks in this study: expanding constraint sets and innovating evolutionary algorithms. Firstly, we propose a base balance strategy aimed at enhancing the thermodynamic properties within DNA fragment groups by diversifying neighboring base combinations. The addition of this strategy achieves a minimum variance of 0.03 for the melting temperature while ensuring orthogonality. It represents a significant improvement compared to previous results and reduces the complexity of controlling reactions. Secondly, our static virus spread algorithm optimizes target DNA fragments by base mutations and virus amplification. Simultaneously,it demonstrates good performance across 23 benchmark functions, highlighting its optimization potential. This work is expected to further refine theoretical shortcomings and offer a convenient tool for DNA fragment optimization. © 2024 IEEE.

The integration of Artificial Itelligence (AI) and edge computing has sparked significant interest in edge inference services. In this paper, we consider delay-sensitive, differential accuracy inference services in a Mobile Edge Computing (MEC) network while meeting user stringent delay and accuracy requirements. We formulate two novel profit maximization problems under static and dynamic settings of service request arrivals, with the aim of maximizing the accumulative profit of admitted requests. We assign differential accuracy service requests to the corresponding resolution instances of their requested service models, assuming that each resolution instance can serve up to L≥ 1 the same type of service requests. Since the profit maximization problem is NP-hard, we first formulate an Integer Linear Program (ILP) solution if the problem size is small or medium;otherwise, we devise a constant randomized algorithm with high probability. Then, we consider dynamic service request admissions without the knowledge of future request arrivals for a given finite time horizon, for which we develop a simple yet effective prediction mechanism to accurately predict the number of different resolution instances of each model needed, and pre-deploy the predicted number of resolution instances into cloudlets to reduce instantiating delays. We then devise an online algorithm with a provable competitive ratio for the dynamic profit maximization problem by leveraging the primal-dual dynamic updating technique. Finally, we evaluate the performance of the proposed algorithms by simulations. The simulation results demonstrate that the proposed algorithms are promising. © 2002-2012 IEEE.

This paper primarily introduces our approach in the 2nd MiGA-IJCAI Challenge Track 1, which focuses on micro-gesture recognition. The micro-gesture dataset has the characteristics of small action amplitude, short duration, and concentrated actions in specific parts. Regarding these issues, We propose a multimodal micro-gesture recognition network based on CLIP. In the video modality, we use a frozen CLIP model as the teacher network and train the student model via distillation. For the skeleton modality, we convert the data into 3D heatmaps, reducing the inherent sparsity of skeleton data. Additionally, we apply text features learned from CLIP to the skeleton modality, enabling interaction between the two models. Our approach achieved an accuracy of 68.9% in micro-gesture recognition. © 2024 Copyright for this paper by its authors.

In the rapidly evolving field of machine learning, advancements in Multiple Object Tracking (MOT) are driven by the integration of sophisticated deep learning models. MOT plays a crucial role in enhancing the quality of multimedia experiences by establishing the groundwork for visual consistency, interactive applications, effective content organization, and a more immersive and captivating user experience across a variety of multimedia platforms. A significant challenge in Multi-Object Tracking (MOT) involves resolving the ID association problem, which entails accurately assigning and maintaining unique identifiers for objects across consecutive frames. Successfully managing this task is crucial for ensuring continuous and consistent tracking of individual objects, thereby enhancing the accuracy and reliability of MOT systems in diverse real-world scenarios. However, it is difficult due to issues like occlusions and variations in appearance. This research investigates the efficacy of a CNN-based approach in achieving accurate ID association in MOT, with a specific focus on the similarity between targets. A tailored Siamese Network is developed and assessed on the created dataset, revealing outstanding performance in terms of accuracy in tracking capabilities. The proposed model adeptly manages challenges such as low-light conditions and occlusions, surpassing state-of-The-Art methodologies. The results affirm the suitability of the CNN-based model for ID association in MOT, underscoring its superior performance and heightened resilience, achieving an accuracy of 91.98%. © 2024 IEEE.

Mobile apps have become widely adopted in our daily lives. To facilitate app discovery, most app markets provide recommendations for users, which may significantly impact how apps are accessed. However, little has been known about the underlying relationships and how they reflect(or affect) user behaviors. To fill this gap, we characterize the app recommendation relationships in the i OS app store from the perspective of the complex network. We collect a dataset containing over 1.3 million apps and 50 million app recommendations. This dataset enables us to construct a complex network that captures app recommendation relationships. Through this, we explore the recommendation relationships between mobile apps and how these relationships reflect or affect user behavior patterns. The insights gained from our research can be valuable for understanding typical user behaviors and identifying potential policy-violating apps.

The use of assistive technology in the field of education is now a common practice in today's tech-driven era. The implementation is quite rampant in all levels and sections of education, including by special needs students with hearing impairments. With the help of technology or Internet of Things (IoT), they are offered with better opportunities to improve their communication and the teaching and learning process especially when it comes to sign language. However, the situation is quite different for Muslim deaf individuals. Sign language is not only used for communication but also as a form for reciting the Quran. Yet, the utilization of technology in the area of sign language for Quranic recitation is still limited. Hence, the goal of this study was to design and develop a sensor-based sign language recognition device consisting of a sensory smart glove and mobile application to detect Arabic sign language alphabets used in Quran recitation. The experimental result shows that the gesture recognition rate of 28 different Arabic alphabet signs, performed by 7 different signers, is 79.08%. The significance of the system lies in its mobility and capability to recognize the hand gestures regardless of the background noise. © 2024 IEEE.
