Drone captured images have overwhelming characteristics including dramatic scale variance, complicated background filled with distractors, and flexible viewpoints, which pose enormous challenges for general object detectors based on common convolutional networks. Recently, the design of vision backbone architectures that use self-attention is an exciting topic. In this work, improved MHSA-Darknet designed to retain sufficient global context information extract more differentiated features...
Object detection on the drone faces a great diversity of challenges such as small object inference, background clutter and wide viewpoint. In contrast to traditional problem in computer vision, bird-like angle can not be transplanted directly from common-in-use methods due special texture sky's view. However, lack comprehensive data set, number algorithms that focus using captured by drones is limited. So VisDrone team gathered massive set organized Vision Meets Drones: A Challenge...
For visual question answering on remote sensing (RSVQA), current methods scarcely consider geospatial objects typically with large-scale differences and positional sensitive properties. Besides, modeling reasoning the relationships between entities have rarely been explored, which leads to one-sided inaccurate answer predictions. In this article, a novel method called spatial hierarchical network (SHRNet) is proposed, endows (RS) (VQA) system enhanced visual–spatial capability. Specifically,...
Circadian rhythm misalignment due to social jet lag, shift work, early morning starts, and delayed bedtimes is becoming common in our modern society. Disturbances of sleep the underlying circadian rhythms are related multiple human diseases, such as obesity, diabetes, cardiovascular disorders, cognitive impairments. Given crucial role microbiota same pathologies caused by disturbance, how gut affected increasing interest. The results this study indicate that acute disturbance sleep-wake...
Macrophage polarization plays an important role in the pathogenesis of COPD emphysema. Changes macrophage remain unclear, while and ferroptosis are essential factors its pathogenesis. Therefore, this study investigated relationship between emphysema.We measured levels matrix metalloproteinases (MMPs) lung tissues patients cigarette smoke (CS)-exposed mice. Flow cytometry was used to determine (THP-M cell) changes. Ferroptosis examined by FerroOrange, Perls' DAB, C11-BODIPY 4-HNE staining....
Nuclear factor E2-related 2 (Nrf2) is involved in oxidative stress and lung inflammation regulates the etiology of chronic obstructive pulmonary disease (COPD).

As a fundamental task for research in satellite videos (SVs), object tracking is used to track the target of interest traffic evaluation, military security, and so forth. The current technology remote sensing field makes it possible moving targets with relatively high frame rate image resolution. However, objects under this special view are often small blurry, making hard extract deep features effectively. result, quite few learning (DL) methods were proposed SVs. In addition, evaluation...
Promoters play an irreplaceable role in biological processes and genetics, which are responsible for stimulating the transcription expression of specific genes. Promoter abnormalities have been found some diseases, level promoter-binding factors can be used as a marker before disease occurs. Hence, detecting promoters from DNA sequences has important significance, particular, distinguishing strong help to elucidate differences gene mechanisms diseases. With introduction third-generation...
Electrocatalytic processes occurring at the heterogeneous interface are complex and their understanding molecular level remains challenging. Atomic force microscope (AFM) can detect interactions down to atomic level, but so far it has been mainly used obtain in-situ images of electrocatalysts. Here for first time, we employ AFM investigate gas evolution a platinum ultramicroelectrode (Pt UME) under electrochemical conditions using noise method. We excess when individual H2 bubble nucleation,...
Introduction: Circulating tumor cells (CTCs) are important prognostic indicators for malignancies. However, a reliable positive/negative cutoff value of non-epithelial (NE+: hybrid and mesenchymal) CTCs phenotype in prostate cancer (PCa) patients has not been established. Here, we aimed to determine the NE+ high-risk (HRPC) after radical prostatectomy (RP). Methods: The was established spiking experiments, were detected 208 HRPC using CanPatrolTM platform. expression function COL1A1 PCa...
In order to improve the channel capacity, waves carrying orbital angular momentum (OAM) in communication systems have attracted much attention. A two-OAM-mode antenna system, which works at 2.4 GHz, is proposed this paper. And a signal transmission experiment performed based on pair of systems. The has planar structure, composed two patch arrays, feeding networks, and one common ground plane. Then, reflection coefficients, radiation patterns, phase distributions system are measured,...
In this letter, two simple and novel circular slot antenna systems to generate OAM waves are proposed. Special feeding networks, which can be used modes, designed at 2.4 GHz feed the antenna. Furthermore, fabricated tested. Both simulation measurement results demonstrate effectiveness of for generating waves.

Stroke is a long-term disability and one of the leading causes death. However, no successful therapeutic intervention available for majority stroke patients. In this study, we explored traditional Chinese medicine Baifuzi (Typhonium giganteum Engl.). We show, at first, that ethanol extract exerts neuroprotective effects against brain damage induced by transient global or focal cerebral ischemia in rats mice. Second, activated large-conductance Ca(2+)-activated K(+) channel (BK(Ca)) channels,...
Dental pulp stem cells (DPSCs) constitute a unique group of endowed with multipotency, self-renewal, and capacity to regenerate the dental tissue. While much has been learned about these in recent years, it is still unclear if each DPSC multipotent or sub-populations DPSCs are “primed” undergo specific differentiation paths. The purpose present study was define whether sub-population uniquely primed vasculogenic differentiation. Permanent-tooth from human exfoliated deciduous teeth (SHED)...
