Abstract: Similarity-based deformable registration of medical images that contain tumor regions often undesirably leads to disproportionate volume changes to tumor regions. An image-registration framework for preserving tumor volumes while promoting similarity in non-tumor part is provided. The framework involves a two-stage process. In the first stage, similarity-based registration is used to identify potential tumor regions by their volume change, generating a soft tumor mask accordingly. In the second stage, a volume-preserving registration network is used. The network uses a novel adaptive volume-preserving loss that penalizes the change in size adaptively based on the masks calculated from the previous stage. The framework balances image similarity and volume preservation in different regions, i.e. non-tumor and tumor regions, by using soft tumor masks to adjust the imposition of volume-preserving loss on each one. It ensures that the tumor volumes are preserved during the registration process.

Abstract: A weakly-supervised framework for segmenting a three-dimensional (3D) medical image incorporates information of geometric prior and contrastive similarity in a loss-based fashion for enhancing distinguishability of an organ in presence of complex organ shape and image artifacts (e.g., low-contrast tissues) in the image. Training images with bounding-box annotations are used to train the framework. The geometric prior is advantageously built on point-cloud representations, which are much more fine-grained and flexible than volume representations, thus serving as better supervision than an inherent property of the bounding-box annotations (i.e. height and width). Furthermore, using contrastive similarity encourages organ pixels to gather around in a contrastive embedding space. It helps more-effectively distinguish low-contrast tissues from the background than using the conventionally-used gray space.

Abstract: A relay directional molecular communication method based on multiple attractants is applied in a field of molecular communication to address the inefficiency of existing technologies. The method for relay nodes is used by fixing three types of attractants, and the relay nodes only release one of the three types of attractants. By using relative priority between two attractants, nanomachines can quickly find a target. Compared with existing multi-attractant multi-relay algorithms, the method does not require many types of attractant resources due to the three types of attractants, saves a variety of the attractant resources, and still achieves an effect greater than three hop relays. It is realized that when a number of the relay nodes is certain, not only the type of attractants used can be reduced, but also the efficiency of finding the target can be maintained.

Abstract: An active tracking system includes an imager configured to image the temperature of a biological tissue and a heating laser configured to heat regions of the biological tissue. The imager locates high-temperature regions of the biological tissue and the heating laser is controlled to point toward target regions of the biological tissue based on the located high-temperature regions. The active tracking system can be used to control a heating laser to continuously heat a target region of a biological tissue even when the target region moves relative to the heating laser. The active tracking system could allow one or more target regions of a biological tissue to be ‘tagged’ with heat by the heating laser and to be tracked even when the one or more target regions move relative to the heating laser. Devices and methods for operating such active tracking systems are also provided.

Abstract: The invention relates to a multiple-tar-cabin electronic cigarette, comprising an atomizer and a battery assembly. The battery assembly supplies electricity to the atomizer. The atomizer comprises tar cabins and heaters that are arranged in a housing. The tar cabins supply tobacco tar to the heaters. After the heaters atomize the tobacco tar, the atomized tobacco tar is brought away by air that enters via an air inlet of the housing, and is smoked via a cigarette holder. The tar cabins include a first tar cabin and a second tar cabin that are mutually isolated. The heaters include a first heater that receives the tobacco tar from the first tar cabin and a second heater that receives the tobacco tar from the second tar cabin. The two tar cabins in the invention can be injected with tobacco tar of different tastes. In this way, users can enjoy cigarettes of different tastes.
