THE EARLY INTERVENTION TENDENCY OF CHINESE CHILDREN WITH COCHLEAR IMPLANTS
From the change of adult unilateral cochlear implantation into young children even under the age of six implant cochlear, sequential bilateral cochlear implantation, which benefit by early hearing screening and technological development of cochlear implants. It is a worldwide trend that simultaneous bilateral cochlear implantation for hearing impaired children under the age of three. Cochlear implants bring changes of education opportunities and choices for children with hearing impairment. Family-centered postoperative early intervention is important, at the same time, hearing impaired children group characteristics tend to be diversified. A growing number of children with cochlear implants study in regular school, consequently, the number of deaf student is decreasing in deaf school. Regular school faces the challenge of lacking of professional teaching staff.
Two-dimensional topological semimetals
The field of two-dimensional topological semimetals, which emerged at the
intersection of two-dimensional materials and topological materials, have been
rapidly developing in recent years. In this article, we briefly review the
progress in this field. Our focus is on the basic concepts and notions, in
order to convey a coherent overview of the field. Some material examples are
discussed to illustrate the concepts. We discuss the outstanding problems in
the field that need to be addressed in future research.Comment: 14 pages, 23 figure
TNFα induces Ca2+ influx to accelerate extrinsic apoptosis in hepatocellular carcinoma cells
BACKGROUND: Tumor necrosis factor-α has been proven an effective anticancer agent in preclinical studies. However, the translation of TNFα from research to clinic has been blocked by significant systemic toxicity and limited efficacy at maximal tolerated dose, which need urgently to be solved.
METHODS: The level of cytosolic Ca
RESULTS: Here, we demonstrated that TNFα induced extracellular Ca
CONCLUSIONS: Our study provides the evidence supporting a novel mechanism by which TNFα induces extracellular C
Vehicle Detection of Multi-source Remote Sensing Data Using Active Fine-tuning Network
Vehicle detection in remote sensing images has attracted increasing interest
in recent years. However, its detection ability is limited due to lack of
well-annotated samples, especially in densely crowded scenes. Furthermore,
since a list of remotely sensed data sources is available, efficient
exploitation of useful information from multi-source data for better vehicle
detection is challenging. To solve the above issues, a multi-source active
fine-tuning vehicle detection (Ms-AFt) framework is proposed, which integrates
transfer learning, segmentation, and active classification into a unified
framework for auto-labeling and detection. The proposed Ms-AFt employs a
fine-tuning network to firstly generate a vehicle training set from an
unlabeled dataset. To cope with the diversity of vehicle categories, a
multi-source based segmentation branch is then designed to construct additional
candidate object sets. The separation of high quality vehicles is realized by a
designed attentive classifications network. Finally, all three branches are
combined to achieve vehicle detection. Extensive experimental results conducted
on two open ISPRS benchmark datasets, namely the Vaihingen village and Potsdam
city datasets, demonstrate the superiority and effectiveness of the proposed
Ms-AFt for vehicle detection. In addition, the generalization ability of Ms-AFt
in dense remote sensing scenes is further verified on stereo aerial imagery of
a large camping site
