In recent years, there has been a renewed interest in mechanisms of flow and turbulence control inspired by aquatic animals. This includes passive mechanisms such as the boundary roughness changes found on shark skin, as well as active boundary modulation, inspired by the viscoelastic properties of dolphin skin. In this work, we present a novel device to control boundary morphology and impact near-boundary flow. We developed this device as a 5-by-5 actuator array, using voice coil motors, and implemented it in the wall of a laminar-to-turbulent flow channel. The actuators are overlaid by a flexible membrane and embedded in the wall of the channel. Each actuator can be controlled individually, and the system can generate wave patterns on the boundary along or across the flow direction. The boundary deformation patterns were quantified using a computer vision approach. The system was tested to assess its impact on near-boundary velocity and turbulence. A DPIV (Digital Particle Image Velocimetry) system was used to quantify velocity fields. Velocity decomposition showed that boundary actuation impacts the mean boundary layer velocity profile. The impact on near-boundary velocity was found to be consistent with a reduction in frictional drag. A numerical tank was set up using Computational Fluid Dynamics, and the results from the model support the laboratory findings. To our knowledge, this is the first such device allowing boundary modulation using individual actuator control that has been implemented and tested in direct contact with water with the impact on flow assessed. A successful implementation of such a device in a natural underwater environment could lead to wide-ranging benefits including increased platform energy-efficiency and reduction of flow-induced noise.

Infrared (IR) spectroscopy is a fundamental technique in analytical chemistry. Recently, deep learning (DL) has drawn great interest as the modeling method of infrared spectral data. However, unlike vision or language tasks, IR spectral data modeling is faced with the problem of calibration transfer and has distinctive characteristics. Introducing the prior knowledge of IR spectroscopy could guide the DL methods to learn representations aligned with the domain-invariant characteristics of spectra, and thus improve the performance. Despite such potential, there is a notable absence of DL methods that incorporate such inductive bias. To this end, we propose Analytical-Chemistry-Informed Transformer (ACT) with two modules informed by the field knowledge in analytical chemistry. First, ACT includes learnable spectral processing inspired by chemometrics, which comprises spectral pre-processing, tokenization, and post-processing. Second, a straightforward yet effective representation learning mechanism, namely spectral-attention, is incorporated into ACT. Spectral-attention utilizes the intra-spectral and inter-spectral correlations to extract spectral representations. Empirical results show that ACT has achieved competitive results in 9 analytical tasks covering applications across pharmacy, chemistry, and agriculture. Compared with existing networks, ACT reduces the root mean square error of prediction (RMSEP) by more than 20% in calibration transfer tasks. These results indicate that DL methods in IR spectroscopy could benefit from the integration of prior knowledge in analytical chemistry.

A kombucha is a tea and sugar fermented by over sixty kinds of yeasts and bacteria. This symbiotic community produces kombucha mats, which are cellulose-based hydrogels. The kombucha mats can be used as an alternative to animal leather in industry and fashion once they have been dried and cured. Prior to this study, we demonstrated that living kombucha mats display dynamic electrical activity and distinct stimulating responses. For use in organic textiles, cured mats of kombucha are inert. To make kombucha wearables functional, it is necessary to incorporate electrical circuits. We demonstrate that creating electrical conductors on kombucha mats is possible. After repeated bending and stretching, the circuits maintain their functionality. In addition, the abilities and electronic properties of the proposed kombucha, such as being lighter, less expensive, and more flexible than conventional electronic systems, pave the way for their use in a diverse range of applications.

3D object recognition has successfully become an appealing research topic in the real-world. However, most existing recognition models unreasonably assume that the categories of 3D objects cannot change over time in the real-world. This unrealistic assumption may result in significant performance degradation for them to learn new classes of 3D objects consecutively, due to the catastrophic forgetting on old learned classes. Moreover, they cannot explore which 3D geometric characteristics are essential to alleviate the catastrophic forgetting on old classes of 3D objects. To tackle the above challenges, we develop a novel Incremental 3D Object Recognition Network (i.e., InOR-Net), which could recognize new classes of 3D objects continuously via overcoming the catastrophic forgetting on old classes. Specifically, a category-guided geometric reasoning is proposed to reason local geometric structures with distinctive 3D characteristics of each class by leveraging intrinsic category information. We then propose a novel critic-induced geometric attention mechanism to distinguish which 3D geometric characteristics within each class are beneficial to overcome the catastrophic forgetting on old classes of 3D objects, while preventing the negative influence of useless 3D characteristics. In addition, a dual adaptive fairness compensations strategy is designed to overcome the forgetting brought by class imbalance, by compensating biased weights and predictions of the classifier. Comparison experiments verify the state-of-the-art performance of the proposed InOR-Net model on several public point cloud datasets. Copyright © 2023, The Authors. All rights reserved.

Ultrasound examination is pivotal in the preoperative assessment of Proximal Humerus Fractures (PHF). To construct a 3D representation of the entire upper arm, it is critical to minimize the relative error between the probe's axis and the skin's normal to secure high-fidelity images. In this research, we introduce an autonomous robotic ultrasound scanning system that facilitates both scanning and 3D reconstruction. To achieve precise control and diminish in-plane motion errors between the probe and skin, we introduce a method for in-plane normal vector search predicated on column similarity. This technique affords high-precision and high-frequency in-plane ultrasound scanning. Experimental findings confirm that our automated system consistently aligns the probe with the skin's normal direction on human arms, thighs, and abdomens. The findings reveal that, relative to traditional algorithms, our method realizes an 84% increase in speed, with an average error below 4.12°. To corroborate the algorithm's efficacy in real-time scanning, we reconstructed the 3D volume of volunteers' upper arms.

In the fields of robotic perception and computer vision, achieving accurate semantic segmentation of low-light or nighttime scenes is challenging. This is primarily due to the limited visibility of objects and the reduced texture and color contrasts among them. To address the issue of limited visibility, we propose a hierarchical gated convolution unit, which simultaneously expands the receptive field and restores edge texture. To address the issue of reduced texture among objects, we propose a dual closed-loop bipartite matching algorithm to establish a total loss function consisting of the unsupervised illumination enhancement loss and supervised intersection-over-union loss, thus enabling the joint minimization of both losses via the Hungarian algorithm. We thus achieve end-to-end training for a semantic segmentation network especially suitable for handling low-light scenes. Experimental results demonstrate that the proposed network surpasses existing methods on the Cityscapes dataset and notably outperforms state-of-the-art methods on both Dark Zurich and Nighttime Driving datasets.
