Abstract	Chemo-mechanical grinding (CMG) is a valid processing method to achieve a low-damage surface of silicon. However, the atomic interfacial mechanism during the CMG is still unclear. Herein, the CMG process of silicon was investigated using first principles and frictional wear tests in which the effects of pressure and speed on the interfacial reaction were comprehensively analyzed. Simulations showed that the formation and breakage of chemical bonds occurred at the CeO

Abstract	Automatic medical image detection aims to utilize artificial intelligence techniques to detect lesions in medical images accurately and efficiently, which is one of the most important tasks in computer-aided diagnosis (CAD) systems, and can be embedded into portable imaging devices for intelligent Point of Care (PoC) Diagnostics. The Feature Pyramid Networks (FPN) based models are widely used deep-learning-based solutions for automatic medical image detection. However, FPN-based medical lesion detection models have two shortcomings: the object position offset problem and the degradation problem of IoU-based loss. Therefore, in this work, we propose a novel FPN-based backbone model, i.e., Multi-Pathway Feature Pyramid Networks with Position Attention Guided Connections and Vertex Distance IoU (abbreviated as PAC-Net), to replace vanilla FPN for more accurate lesion detection, where two innovative improvements, a position attention guided connection (PAC) module and Vertex Distance IoU Vertex Distance Intersection over Union loss, are proposed to address the above-mentioned shortcomings of vanilla FPN, respectively. Extensive experiments are conducted on a public medical image detection dataset, i.e., Deeplesion, and the results showed that i) PAC-Net outperforms all state-of-the-art FPN-based depth models in both evaluation metrics of lesion detection on the DeepLesion dataset, ii) the proposed PAC module and VDIoU loss are both effective and important for PAC-Net to achieve a superior performance in automatic medical image detection tasks, and iii) the proposed VDIoU loss converges more quickly than the existing IoU-based losses, making PAC-Net an accurate and also highly efficient 3D medical image detection model.

Abstract	Grip strength is a biomarker of frailty and an evaluation indicator of brain health, cardiovascular morbidity, and psychological health. Yet, the development of a reliable, interactive, and point-of-care device for comprehensive multi-sensing of hand grip status is challenging. Here, a relation between soft buckling metamaterial deformations and built piezoelectric voltage signals is uncovered to achieve multiple sensing of maximal grip force, grip speed, grip impulse, and endurance indicators. A metamaterial computational sensor design is established by hyperelastic model that governs the mechanical characterization, machine learning models for computational sensing, and graphical user interface to provide visual cues. A exemplify grip measurement for left and right hands of seven elderly campus workers is conducted. By taking indicators of grip status as input parameters, human-computer interactive games are incorporated into the computational sensor to improve the user compliance with measurement protocols. Two elderly female schizophrenic patients are participated in the real-time interactive point-of-care grip assessment and training for potentially sarcopenia screening. The attractive features of this advanced intelligent metamaterial computational sensing system are crucial to establish a point-of-care biomechanical platform and advancing the human-computer interactive healthcare, ultimately contributing to a global health ecosystem.

Abstract	Multidirectional approaches are essential for harnessing mechanical energy of random varying directions. Traditional multidirectional technologies are difficult to effectively harvesting vibration energy in complex physical environments due to their complex and auxiliary designs. Inspired by the vibrational stabilization of hummingbirds to maintain stable in hovering flight for any desired direction, we propose an omnidirectional piezoelectric energy harvester with the compact coaxial design and autonomous direction regulation capability. Our design scheme is to endow all-around directional sensitivity in a single oscillator rather than multiple installation directions of the oscillators. The dynamics of this omnidirectional vibration energy harvesting device are described for explaining the autonomous direction regulation mechanism realized by vibrational stabilization. Compared to its unidirectional counterpart, this omnidirectional energy harvester with the autonomous direction-regulating ability shows a 696% increase in maximum open-circuit voltage and 49.0 times higher maximum power density when the external excitation direction is perpendicular to the initial vibration direction. Practical applications of powering an electronic clock demonstrate the feasibility of the proposed omnidirectional energy harvester for the engineering community. Field experiments of harvesting energy from bicycle riding or human movement to charge a capacitor also validate the significant improvement of the direction-regulating design strategy in endowing an all-around uniform directional sensitivity. The vibrational stabilization mechanism provides a new design philosophy for omnidirectional energy harvesters. With its high flexibility and desirable enhancement, this direction-regulating design strategy has the potential to be applied in vibration energy harvesters with different mechanisms (electrostatic, electromagnetic or triboelectric ones) to extend their multidirectional capabilities.

Abstract	Background: Massive or submassive pulmonary embolism (PE) carries a high mortality. Percutaneous mechanical thrombectomy using the Angiojet system is accepted for the treatment of PE. Here, we reported two submassive PE cases who were treated with the Angiojet system successfully, to provide some advice for the therapy of submassive PE. Method: Two patients with suffocation were admitted to our hospital. One patient was accompanied by lower blood pressure (20% lower than basal blood pressure) and higher pulmonary artery pressure (89 mmHg); the other patient had larger right ventricular transverse diameter (46 mm), decreased left ventricular end diastolic anteroposterior diameter (34 mm), and higher heartbeats (107 heartbeats per minute). Pulmonary artery computed tomography angiography showed bilateral pulmonary embolism. Result: The Angiojet system with a high-pressure jet spray pattern (urokinase 25 wiu + sodium chloride injection 50 ml) was used. Intravascular thrombolysis by urokinase (100 wiu/day for 1 day) was done after being back in the ward. And low molecular weight heparin was used in hospitalization, and rivaroxaban was used after discharge. Both patients were treated successfully. However, the level of platelet was significantly lower in one patient after Angiojet system usage and recovered to the preoperative level the next day. Another patient suffered from bradyarrhythmias during the usage of Angiojet, and bradyarrhythmias disappeared when the Angiojet system stopped. Pulmonary embolism was cured after 3 months in both patients. Conclusion: Angiojet could be a simple, safe, and well-tolerated treatment for massive or submassive PE. And hematocrit, platelet, kidney function, and heart rhythm should be monitored during perioperation.

Abstract	Harvested wood/bamboo products (HWP/HBP) constitute a large global carbon stock. However, the contribution of HBP to carbon stocks has been neglected in mixed wood and bamboo data, especially in China. Therefore, the production approach and the first-order decay method were used to estimate the spatiotemporal carbon stock change in HWP/HBP based on provincial production data from the China Forestry Statistical Yearbooks for 1987-2020. The results showed that China's total carbon stocks of HWP and HBP were 328.7 teragram carbon (TgC) and 129.7 TgC between 1987 and 2020. Of this, the HWP carbon stock was mainly sourced from three provinces across the north and south: Guangxi (60.8 TgC), Heilongjiang (37.2 TgC), and Fujian (24.2 TgC), and HBP carbon stock was mainly sourced from three southern provinces: Fujian (33.4 TgC), Guangxi (20.3 TgC), and Zhejiang (13.7 TgC). The proportion of the HBP carbon stock in the total carbon stock increased from 20% in 2010 to 28% in 2020, indicating that bamboo products play an important role in the accumulation of carbon stocks in China. The differences in contributions to spatiotemporal trends between the provinces provide more specific information to make precise decisions about forest management and carbon sequestration.

Abstract	Currently, the practicability of vibration energy harvesting devices is restricted by narrow resonant bandwidths. To realize broadband, high-efficiency vibration energy harvesting, here we propose a flute-inspired mechanical-intelligent piezoelectric energy harvester to achieve self-tracking vibration frequency without manual interventions. This harvester adjusts its natural frequency in a way reminiscent of how the tone of a flute is altered (i.e., by moving a sliding mass on the longitudinal arranged hole of a cantilever beam). The mechanical intelligence is reflected in self-tuning and self-locking following its dynamic responses. The natural frequency of the proposed device approaches the external excitation frequency by self-tuning, and the resonant state is stably maintained by self-locking. Comparison experiments with its linear counterpart, this flute-inspired mechanical-intelligent vibration energy harvester demonstrates a significant improvement of 610% in working bandwidth and an increase in power of 348%. Compared with the tunable beam-slider structure without mechanical-intelligence, the proposed energy harvester shows 235% increasing in operating bandwidth and 659% increasing in working efficiency. Practical applications of powering an electronic clock and charging a capacitor show the feasibility of this energy harvester used for the engineering community. This study provides a mechanical-intelligent design approach for piezoelectric vibration energy harvester, which may also be applied to other vibration energy harvesters using electromagnetic, triboelectric or hybrid transductions.

Abstract	Broadening the working bandwidth of piezoelectric energy harvesting devices is of great importance owing to the wide frequency spectrum of environmental vibrations. Efforts, including stiffness nonlinearity and multimodal optimization, have been proposed to improve harvesters’ responses towards the broadband frequency region. This paper designs a spring-based bistable energy harvester (SBEH) and proposes its two configurations (SBEH-sup and SBEHsub) to achieve high working efficiency under different excitation levels through inter-well modulation. The nonlinear force produced by the compressed springs generates nonlinear dynamical responses, and thus broadens the effective bandwidth of the SBEH. Compared to the SBEH-sup configuration, the SBEH-sub configuration further utilizes magnetic force to dynamically alter the potential energy threshold in the nonlinear system, which contributes to the SBEH maintaining inter-well motion and enhancing the working performance under lower intensity excitation. The working mechanisms of the SBEH-sup configuration and the SBEH-sub configuration are revealed by derived mathematical models. The feasibility of the SBEH with two proposed configurations is verified by experimental tests. Compared with its linear counterpart, the significant advantages in the SBEH-sup configuration show 673% increment in effective bandwidth and 179% increment in working efficiency under suprathreshold-level excitation. Compared with the SBEH-sup configuration, the SBEH-sub configuration further broadens the operating bandwidth by 838% and enhances the working efficiency by 269% under subthreshold-level excitation. This spring-based bistable energy harvester provides a new design philosophy for nonlinear energy harvesters, its two configurations with inter-well modulation achieve satisfactory performance for scavenging energy from different-level vibrations.
