    Abstract Single image super-resolution (SISR) aims to recover the high-resolution (HR) image from its low-resolution (LR) input image. With the development of deep learning, SISR has achieved great progress. However, It is still a challenge to restore the real-world LR image with complicated authentic degradations. Therefore, we propose FAN, a frequency aggregation network, to address the real-world image super-resolu-tion problem. Specifically, we extract different frequencies of the LR image and pass them to a channel attention-grouped residual dense network (CA-GRDB) individually to output corresponding feature maps. And then aggregating these residual dense feature maps adaptively to recover the HR image with enhanced details and textures. We conduct extensive experiments quantitatively and qualitatively to verify that our FAN performs well on the real image super-resolution task of AIM 2020 challenge. According to the released final results, our team SR-IM achieves the fourth place on the X4 track with PSNR of 31.1735 and SSIM of 0.8728.

    Abstract Multiple variables determine the success of an escape response of an animal, and the rapidity of the escape manoeuvre is often the most important. Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Here, we explore the dynamic and mechanistic features behind this escape manoeuvre. The escape responses of fan worms were recorded by high-speed videography and quantified by computerized motion analysis, showing an ultrahigh retraction speed of 272±135 mm s-1 (8±4 body lengths s-1). We found that fan worms possess powerful muscle-driven systems, which can generate contractive forces up to 36 times their body weight. In order to achieve these rapid, forceful movements through seawater without damaging their tentacles, fan worms have developed functional morphological adaptations to reduce fluidic drag, including the flattening of their radiolar pinnules and the deformation of bodily segmental ridges. Our hydrodynamic models indicate that these mechanical processes can decrease fluidic drag by 47%, trapped mass by 75% and friction coefficient by 89%. These strategies allow fan worms to execute rapid escape responses and could inspire the design of fast in-pipe robots.

    Abstract The needs fulfilled by sleep are unknown, though the effects of insufficient sleep are manifold. To better understand how the need to sleep is sensed and discharged, much effort has gone into identifying the neural circuits involved in regulating arousal, especially those that promote sleep. In prevailing models, the dorsal fan-shaped body (dFB) plays a central role in this process in the fly brain. In the present study we manipulated various properties of the dFB including its electrical activity, synaptic output, and endogenous gene expression. In each of these experimental contexts we were unable to identify any effect on sleep that could be unambiguously mapped to the dFB. Furthermore, we found evidence that sleep phenotypes previously attributed to the dFB were caused by genetic manipulations that inadvertently targeted the ventral nerve cord. We also examined expression of two genes whose purported effects have been attributed to functions within a specific subpopulation of dFB neurons. In both cases we found little to no expression in the expected cells. Collectively, our results cast doubt on the prevailing hypothesis that the dFB plays a central role in promoting sleep.

    Abstract Background: For costal cartilage-based rhinoplasty, a method that could properly manage warping of the columellar strut graft and facilitate establishing a stable cartilaginous framework remains desirable. In this study, the authors present a new graft design named bilateral septal extension strut. It utilizes a pair of cartilage grafts with the shape of a fan, which are bilaterally fixated to the septum. Such "sandwiched" structure undertakes the combined functional roles of a columellar strut and a septal extension graft.
    Methods: Fifty-two female patients, ranging in age from 18 to 37 years, received augmentation rhinoplasty surgery based on the bilateral septal extension strut. Among these patients, 20 of them were primary cases, 26 secondary, and other six cases were tertiary.
    Results: Patients' own evaluations on the overall improvements in the nose rendered high satisfaction rate. There was no case of graft extrusion or infections. During the long-term follow-up, one case presented dorsal onlay graft warping and two cases presented in significant asymmetrical nostrils due to the deviation of the columellar at 12 months postoperatively and were corrected in the revision surgery.
    Conclusions: The application of the bilateral septal extension struts can help mitigate the negative impact of strut graft warping, making it more manageable. As a result, reliable as well as sustainable support for both tip and lower lateral cartilages can be achieved in the long term.

    Abstract Objective: This prospective randomized study aimed to investigate the accuracy, radiation exposure, and surgical workflow optimization of a novel intraoperative spinal navigation system using preoperative fan-beam (FB) CT versus the classic intraoperative cone-beam (CB) CT in patients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
    Methods: In this two-arm, single-center, randomized study, the authors evaluated the safety and clinical outcomes of a novel navigation system for pedicle screw placement in spine surgery.
    Results: The accuracy of pedicle screw placement in the experimental group (FB group) was 94.38%, while it was 94.55% in the control group (CB group). Notably, the intraoperative radiation exposure to patients in the FB CT group (mean 0.361 ± 0.261 mSv) was significantly lower than that in the CB CT group (mean 6.526 ± 13.591 mSv) (p < 0.0001). Furthermore, the intraoperative preparation time for screw placement in the FB group (mean 10.6 ± 5.62 minutes) was significantly lower than that in the CB group (mean 17.6 ± 5.59 minutes) (p = 0.0004). No significant differences were observed for blood loss during surgery, total radiation exposure to surgeons, mean time for inserting a single pedicle screw, revision surgery rate, patients' reported outcomes, and length of postoperative hospital stay between the two groups. Significant differences were observed for intraoperative radiation exposure to patients and the preparation time for pedicle screw placement.
    Conclusions: The preoperative FB CT-based intraoperative spinal navigation system demonstrated comparable accuracy and safety when compared with the intraoperative CB CT-based system. Moreover, the FB CT-based system had a shorter time for screw placement and reduced intraoperative radiation exposure to patients. These findings support the potential benefits of adopting this novel navigation system to enhance surgical precision and reduce radiation-related risks in MIS-TLIF procedures.

    Abstract Pineapple plant usually has a capitulum. However, a fan-shaped inflorescence was exceptionally evolved in pineapple, having multiple crown buds. In order to reveal the molecular mechanisms of the formation of the fan-shaped inflorescence, fruit traits and the transcriptional differences between the fan-shaped inflorescence and the wild-shaped inflorescence pineapples were analyzed in three tissues, i.e., the flower stem apex, the base of the inflorescence, and the inflorescence axis. The weight (i.e., individual yield) of fan-shaped fruit is 4.5 times that of wild-shaped fruit;and non-significant difference in soluble solids, soluble sugar, titratable acid, and Vitamin C was found. Between the fan-shaped inflorescence and wild-shaped inflorescence, a total of 5370 differentially expressed genes were identified across the three tissues. Of these genes, there were 489 overlapping differentially expressed genes in all three tissue comparisons. Between the two pineapples, functional analysis indicated that 444 transcription factors and 206 inflorescence development-related genes were differentially expressed in at least one tissue comparison, while 45 transcription factors and 21 inflorescence development-related genes were overlapped across three tissues. Among the 489 overlapping differentially expressed genes in the three tissue comparisons, excluding the inflorescence development-related genes and transcription factors, 80 of them revealed a higher percentage of involvement in the biological processes relating to response to auxin, and reproductive processes. RNA-seq value and real-time quantitative PCR analysis exhibited the similar gene expression patterns in the three tissues. Our result provided novel cues for understanding the molecular mechanisms of the formation of the fan-shaped inflorescence in pineapple, making a valuable resource for the study of plant breeding and the speciation of pineapple.

    Abstract The fan nozzle is widely used in the process of pest control in agriculture and forestry. The spray angle of the nozzle is an important characterization parameter in the atomization of liquids. The spray angle of the nozzle is an important characterizing parameter in the liquid atomization process. It affects the flow field at the exit of the nozzle, thereby affecting the size and velocity of the droplets, and further affecting the deposition effect of the droplets on the crop. Therefore, its research is of great significance for improving the deposition of liquid on plants and controlling pests and related diseases. Based on the classical theory of predecessors and considering the parameters of the flat fan nozzle, we further optimized the theory at the structural level by means of a simulation test and built a spray angle theoretical model taking into account the parameters of the inner chamber of the nozzle. We arrived at the following conclusions: (1) the average error of the spray angle measured by the simulation test and the actual test spray angle was 2.95%, the maximum spray angle deviation value was 2.81°, and the result proves that the simulation test parameter setting is accurate; and (2) the average error between the actual measured value and the theoretical model calculation value was 3.56%, the maximum spray angle deviation was 4°, through the actual test comparison, and the spray angle error of the theoretical model was within the allowable error range of industry production. It was proved that the model could effectively reflect the changing law of spray angle of the flat fan nozzle.

    Abstract Context: The use of a handheld or electric fan has been proposed as one component of the complex clinical interventions used in the relief of dyspnea; however, there is a lack of consensus regarding its efficacy.
    Objectives: We performed a systematic review to determine the effectiveness of fan therapy for the treatment of dyspnea.
    Methods: We searched the Medline, EMBASE, Web of Science, Scopus, CINAHL, PsycInfo, and Cochrane Library databases to identify all fan therapy studies published from January 1, 1946 to September 31, 2018. The search terms included "dyspnea," "dysponea," "dyspneic," "short of breath," "shortness of breath," "breathless," "breathlessness," "breathing difficulty," "labored breathing," and "fan." Searches were limited to articles in English or Chinese. The bibliographies of identified articles were also manually searched. Three authors independently assessed papers for inclusion.
    Results: Ten of the 92 unique records identified met the inclusion criteria (nine randomized controlled trials and one cohort study). Most studies (80%) were conducted in the hospital setting, and none were double blinded. Nearly half (159 [46%]) of the 344 total subjects had cancer. The most common nonmalignant disease was chronic obstructive pulmonary disease. The most common duration of fan therapy was five minutes. Six studies (60%) reported a significant improvement in dyspnea with fan therapy. There are two ongoing trials being conducted based on a search of trial registries.
    Conclusion: Limited direct evidence from randomized controlled trials indicates that fan therapy may effectively alleviate dyspnea. Additional trials are warranted to confirm this finding and explore the use of fan therapy for the treatment of dyspnea in more diverse populations and settings.
