Abstract. We have designed and characterized a new inlet aerodynamic lens for the Aerodyne aerosol mass spectrometer (AMS) that transmits particles between 80 nm more than 3 μm in vacuum diameter. The design of was optimized with computational fluid dynamics (CFD) modeling particle trajectories. Major changes include redesigned critical orifice holder valve assembly, addition relaxation chamber behind orifice, higher operating pressure. transmission efficiency experimentally size-selected...

Hyperspectral image (HSI) classification is widely used in the analysis of remotely sensed images. Deep learning techniques, especially CNN, have greatly improved performance over traditional machine methods due to their robust feature extraction capability. However, CNN methods, which typically use small receptive fields, still struggle model long-term dependencies effectively. On other hand, transformers based on multi-head self-attention(MHSA) mechanism may overlook subtle spectral...
Reconfigurable intelligent surface (RIS) is a two-dimensional periodic structure integrated with large number of reflective elements, which can manipulate electromagnetic waves in digital way, offering great potentials for wireless communication and radar detection applications. However, conventional RIS designs highly rely on extensive full-wave EM simulations that are extremely time-consuming. To address this challenge, we propose machine-learning-assisted approach efficient design. An...

This article studies a mobile-edge computing (MEC) system, where an access point (AP) and relay node serve user terminal over multicarrier subchannels. In the MEC can assist not only task offloading but also computation. Aiming at minimizing total energy consumption relay, resource allocations, such as subcarrier allocation, power partition, time computation are to be optimized, subject given delay constraint. To achieve this goal, novel cooperative protocol is designed, subchannels utilized...

A sum-rate maximization problem formulated...
Transformer-based methods have achieved significant success in hyperspectral image (HSI) classification, which attribute to the strong capability of capturing global dependencies from input. However, existing HSI classification are challenged retrieving sufficient abound local information using linear projection modules. Moreover, they do not fully use hierarchical representations extracted original images. To overcome these challenges, this paper proposes a novel transformer model, called...
Energy harvesting (EH) is promising to solve energy scarcity problem in energy-constrained wireless networks.

By jointly designing TS ratios of processing at relay, as well allocation over all subcarriers our objective...

Considering discrete nature messenger molecules, design CSK essentially nonlinear integer programming problem. However, due to nonconvexity...

This article studies a network where transmitter communicates with receiver by hybrid communications that consist of passive information transmission (IT) via backscatter communication (BC) and active IT wireless-powered (WPC). Because the circuit energy consumption in BC is much lower than WPC, usually achieves higher data rate WPC. Thus, it was suggested literature throughput performance could not be improved communications. However, our work this demonstrates can enhanced newly designed...
