Low-light image enhancement with retinex theory optimized by improved whale optimization algorithm

Abstract To solve the problems of insufficient contrast, blurred details, and color distortion in low-light image Enhancement, this paper proposes a Low-Light Image Enhancement with Retinex Theory Optimized by Improved Whale Optimization Algorithm(WOA). The method innovatively em...

Transformer-Guided Interference-Aware 3D Path Planning for UAV Navigation in Urban Voxel Environments

Urban unmanned aerial vehicle (UAV) navigation may require path planning that accounts for geometric obstacles and spatially varying communication-related risk. This paper presents a transformer-guided interference-aware 3D path-planning method for urban voxel environments. A 3D...

Qudit W and Greenberger–Horne–Zeilinger states on a two-photon chip

Abstract High-dimensional quantum entangled states exhibit unique properties. While generalizations like qudit Bell, Greenberger–Horne–Zeilinger (GHZ), and Cluster states have been studied, the qudit W states remain underexplored. We discover that a superposition of qudit Dicke s...

Security in the Fine‐Tuning Lifecycle of Large Language Models: Threats, Defenses, Evaluation, and Future Directions

ABSTRACT Background Fine‐tuning has become a core mechanism for adapting pretrained Large Language Models (LLMs) to downstream tasks. However, the dependence of fine‐tuning on training data, parameter update mechanisms, and reusable components provides entry points for attackers....

Optimizing one-dimensional bin packing for conveyor belt logistics via pointer-network-based A2C and heuristics

The one-dimensional Bin Packing Problem (1D-BPP) poses significant challenges in logistics, particularly for optimizing item packing sequences in warehouse conveyor belt systems. This paper proposes a Deep Reinforcement Learning (DRL) approach using Advantage Actor-Critic (A2C) i...

RSP-net: an effective framework for automated root cause location in wireless network optimization scene

Currently, mobile communication network has become a very popular way to provide communication service for individual, industry and commerce. In wireless environment, the base stations provide the wireless access function for users, which play a key role in the communication syst...

Efficient Real-Time Monitoring of Vibrations Transmitted to the Human Body

Abstract Mechanical vibrations transmitted to the human body, particularly in sectors such as transportation, construction, and agriculture, represent a serious occupational hazard. Whole-body vibrations (WBVs), in particular, have been linked to musculoskeletal disorders and imp...
