The automatic detection and identification of fish from underwater videos is great significance for fishery resource assessment ecological environment monitoring. However, due to the poor quality images unconstrained movement, traditional hand-designed feature extraction methods or convolutional neural network (CNN)-based object algorithms cannot meet requirements in real scenes. Therefore, realize recognition localization a complex environment, this paper proposes novel composite framework...
In intensive aquaculture, the number of fish in a shoal can provide valuable input for development intelligent production management systems. However, traditional artificial sampling method is not only time consuming and laborious, but also may put pressure on fish. To solve above problems, this paper proposes an automatic counting based hybrid neural network model to realize real-time, accurate, objective, lossless population far offshore salmon mariculture. A multi-column convolution...
Human activities have globally increased atmospheric nitrogen (N) deposition, which has enhanced the risk of ecosystem N losses. Phosphorus (P), as a macroelement required for life, is closely linked to biogeochemical cycle N. Therefore, quantifying how soil responds different P supply levels important. Here we examined responses dynamics altered using addition experiment (+0, +25, +50, +100 kg ha−1 yr−1) in an evergreen broadleaf mixed plantation subtropical China. We...
Abstract A 2-year field experiment was conducted on maize ( Zea mays L.) to explore effective ways decrease soil CO 2 emissions and increase grain yield. Treatments established were: (1) no mulching with urea, (2) controlled release fertiliser (CRF), (3) transparent plastic-film (PMt) (4) PMt CRF, (5) black (PMb) (6) PMb CRF. During the early growth stages, were noted as > mulching, this order reversed in late stages. This trend result of topsoil temperature dynamics. There significant...
The refined monitoring and identification of fishing operations by vessels is great significance value to vessels. In order solve the problem inaccurate statistics current Engraulis japonicus quota classification, this paper proposes an improved algorithm based on YOLOv5. This method introduces SENet attention mechanism into YOLOv5 backbone network structure, integrates target information in different periods operations, reduces interference complex backgrounds, improves precision model...
Hydroxyapatite (HA), a typical inorganic component of bone, is widely utilized biomaterial for bone tissue repair and regeneration due to its excellent properties. Inspired by the recent findings on important roles protein in biomineralization natural structure fish scales, keratin was chosen as template modulating assembly HA nanocrystals. A series nanocrystals with different sizes were synthesized adjusting concentration partially hydrolyzed keratin. The compositions prepared characterized...
The synergistic effect of total ionizing dose (TID) and single event gate rupture (SEGR) in SiC power metal–oxide–semiconductor field transistors (MOSFETs) is investigated via simulation. device found to be more sensitive SEGR with TID increasing, especially at higher temperature. microscopic mechanism revealed the increased trapped charges induced by subsequent enhancement electric intensity inside oxide layer.
Sea cucumber manual monitoring and fishing present various issues, including high expense risk. Meanwhile, compared to underwater bionic robots, employing autonomous robots for sea capture also has drawbacks, low propulsion efficiency significant noise. Therefore, this paper is concerned with the design of a robotic manta ray recognition, localization, approach. First, developed prototype system framework applied real-time target search are elaborated. Second, by improved YOLOv5 object...
The compressor tonal noise of a low-speed marine diesel engine turbocharger is investigated with numerical method. Nine operating conditions on four different rotating speed lines are analyzed; the include near-choke conditions, near-surge and peak efficiency conditions. Numerical predictions global variables compared experimental measurements, good agreement achieved. pressure fluctuation at all presents strong periodicity, prominent peaks amplitude appear blade passing frequency its...

It has been proven that magnetic resonance (MR) and ultrasound imaging are useful tools in the quantification of carotid atherosclerotic plaques. However, there only a few pieces evidence to illustrate links quantitative measurements plaques between MR imaging. This study looked compare investigate their relationship three-dimensional (3D) vessel wall two-dimensional (2D) imaging.Seventy-five asymptomatic elderly subjects (mean age: 73.3±5.7 years; 45 males) with diagnosed by both were...
The adaptive strategies of bird song frequencies in urbanized areas provide a unique system to understand the sounds response conditions. Using passive acoustic monitoring and automatic sound recognition technology, we explored frequency variations six common urban species their association with habitat structures. Our results demonstrated that environments were significantly higher than outskirts rural areas. Habitat vegetation structure noise levels identified as crucial factors shaping...
