    Abstract Satellite edge computing has attracted the attention of many scholars due to its extensive coverage and low delay. Satellite edge computing research remains focused on on-orbit task scheduling. However, existing research has not considered the situation where heavily loaded satellites cannot participate in offloading. To solve this problem, this study first models the task scheduling of dynamic satellite networks as a minimization problem that considers both the weighted delay and energy consumption. In addition, a hybrid genetic binary particle swarm optimization (GABPSO) algorithm is proposed to solve this optimization problem. The simulation results demonstrate that the proposed method outperforms the other three baseline algorithms.

    Abstract Analyzing the vibration features of a shipboard stabilized platform (SSP) is significant to the design or vibration compensation of a marine gravimetric survey vibration isolation system. Empirical Fourier decomposition (EFD) is a recently developed method for nonlinear and non-stationary signal decomposition. However, the spectral segmentation boundary needs to be set in advance according to sophisticated experience, and it is easy to be disturbed by noise, and the decomposition result is inaccurate. In order to accurately extract the nonlinear vibration characteristics of SSP, this paper proposes a new method called power spectrum envelope adaptive empirical Fourier decomposition (PSEEFD). Firstly, the number of selected modal decomposition is determined based on the mutual information to realize adaptive segmentation. Then, the improved power spectrum envelope segmentation method is adopted to effectively diminish the interference of noise since the segmentation boundary is formed by the minimum of the adjacent extreme points enveloped by the maximum value of the power spectrum. The spectrum segments obtained from segmentation contain less interference. Finally, the component signal in each frequency band is reconstructed by inverse fast Fourier transform, and the instantaneous frequency signal component with physical significance is obtained. Through the analysis of vibration simulation signals and measured data of SSP, the proposed method is compared with EMD, AFVMD, EWT and EFD. The results show that PSEEFD has a well suppression of noise interference and can effectively extract the characteristics of nonlinear vibration signals.

    Abstract Atomic gravimeter has been more frequently applied under complex and dynamic environments, but its measurement accuracy is seriously hampered by vibration-induced noise. In this case, vibration compensation provides a way to enhance the accuracy of gravity measurements by correcting the phase noise that resulted from the vibration of a Raman reflector, and improving the fitting of an interference fringe. An accurate estimation of the transfer function of vibration between the Raman reflector and the sensor plays a significant role in optimizing the effect of vibration compensation. For this reason, a vibration compensation approach was explored based on EO (equilibrium optimizer) for estimating the transfer function simplified model of a Raman reflector, and it was used to correct the interference fringe of an atomic gravimeter. The test results revealed that this approach greatly restored the actual vibration of the Raman reflector in a complex vibration environment. With a vibration compensation algorithm, it achieved the correction and fitting of the original interference fringe. In general, it dramatically reduced the RMSE (root mean square error) at the time of fitting and significantly improved the residual error in the gravity measurement. Compared with other conventional algorithms, such as GA (genetic algorithm) and PSO (particle swarm optimization), this approach realized a faster convergence and better optimization, so as to ensure more accurate gravity measurements. The study of this vibration compensation approach could provide a reference for the application of an atomic gravimeter in a wider and more complex environment.

    Abstract To change the binary structure of nanotube and nanotube array in vertically aligned carbon nanotube arrays, this work deposits regularly arranged amorphous alumina sheets on the classical array growth catalyst (10 nm-thick alumina and 2 nm-thick iron) and obtains an array similar to the Medusa head. Subsequent experiments revealed that these alumina sheets show both unstable and stable qualities during growth: unstable in that they thermally deform and change their newly discovered characteristics of blocking carbon source diffusion, which regulates the nanotube growth order in specific areas; stable in that they withstand the deformation caused by heat and sequential growth of nanotubes, serving as a substrate and buffer layer for Medusa's hair, i.e., nanotube bundles on the array surface. Their combination splits this binary structure into a tertiary architecture consisting of nanotubes, nanotube bundles, and the array spanning nano-, micro-, and milli-meter. Benefiting from this structure, this array exhibits a unique near-isotropic adhesion characteristic compared to existing reports and outperforms classical and patterned arrays with the same classical catalyst and growth conditions.

    Abstract Ship detection for high-resolution optical remote sensing (HRORS) imagery is widely applicable to Navy construction, maritime transportation, maritime safety, port management, and many other fields. Optical remote-sensing images can easily be disturbed by thin cloud, light, and some complex environmental conditions, which makes the task of ship detection challenging. In this paper, we propose a new general detection network framework to recognize ships with arbitrary-orientation, in which we use a novel way to define the rotating rectangular box, remove the dependence on methods with angle parameters of the target. We propose a new feature fusion module (FFM) to integrate the semantic information, which enhances the feature extraction from the shallow network, and effectively improve the detection of small targets. We also employ one attention module (AM) to adaptively select meaningful features, which enhance the ability of feature extraction for complex environmental conditions. The multi-directional anchor size and length-width ratio are designed based on the clustering technique to improve the convergence speed and accuracy. Experiments on the public HRORS ship detection dataset HRSC2016 and the ship dataset SSD2020 collected from Google Earth have shown better performance compared with some conventional methods, which prove the feasibility and effectiveness of our proposed network architecture.

    Abstract Frailty is characterized by a state of vulnerability to poor resolution of homoeostasis after a stressor event and is a consequence of age-related decline in many physiological systems during a lifetime. To access the association between frailty and delayed recovery of gastrointestinal function in patients undergoing elective colorectal cancer resections, 241 patients who had undergone elective colorectal cancer resections from July 2015 to August 2017 were investigated. The association of frailty with delayed recovery of gastrointestinal function, length of stay (LOS), and whether or not to transfer into intensive care unit (ICU) were analyzed. For the entire cohort, 164 (68.0%) of total patients experienced the early recovery of gastrointestinal function, 67 (27.8%) delayed recovery, and 10 (4.1%) patients occurred postoperative ileus (POI) or anastomotic leakage (AL). Low Modified Frailty Index (mFI) score was associated with statistically decreased odds ratios of 0.276 (95% CI, 0.095-0.808;

    Abstract Introduction: The aim of this article was to compare and analyze the outcomes of surgical repair and watchful waiting (WW) in the treatment of asymptomatic or minimally symptomatic inguinal hernias.
    Methods: A systematic literature review was undertaken to identify studies that compare surgical repair and watchful waiting in asymptomatic or minimally symptomatic inguinal hernias. And all related data matching our standards were abstracted for Meta-analysis with RevMan 5.0.1.
    Results: Less pain was observed in Operation group. However, there were no significant differences in Physical Component Score (PCS), mortality, surgical complications and postoperative hernia recurrence between WW group and Operation group. But a great number of patients would develop significant hernia-related symptoms and cross over to surgery over time in WW group.
    Conclusions: Patients have relative less pain in operation group compared with WW group. Although WW is safe in patients with asymptomatic or minimally symptomatic inguinal hernias, however, this strategy would merely delay rather than avoid surgical repair of hernias in the majority of inguinal hernia patients.
