Since the preparation of labeled datafor training semantic segmentation networks of pointclouds is a time-consuming process, weakly supervisedapproaches have been introduced to learn fromonly a small fraction of data. These methods aretypically based on learning with contrastive losses whileautomatically deriving per-point pseudo-labels from asparse set of user-annotated labels. In this paper, ourkey observation is that the selection of which samplesto annotate is as important as how these samplesare used for training. Thus, we introduce a methodfor weakly supervised segmentation of 3D scenes thatcombines self-training with active learning. Activelearning selects points for annotation that are likelyto result in improvements to the trained model, whileself-training makes efficient use of the user-providedlabels for learning the model. We demonstrate thatour approach leads to an effective method that providesimprovements in scene segmentation over previouswork and baselines, while requiring only a few userannotations.

人们对符合环保要求涂料的质量愈来愈重视，因此对合成聚酯粉末涂料用树脂的人员提出了越来越严格的要求。但是由于可选用的单体种类有限，配方人员设计高性能树脂的能力受到了限制。一旦一些用于粉末涂料树脂的新型单体问世，人们立即要了解其对于玻璃化转变温度Ｔｇ、熔融粘度的影响，因为这些参数表征了粉末涂料的稳定性和固化时的流动性。本文将重点讨论最近用于合成粉末涂料用树脂的一些二元醇和二元酸对这些重要参数的影响。

In 2004, docetaxel was approved for the treatment of metastatic castration-resistant prostate cancer （mCRPC）. For the next several years, there was a lull in drug approvals. However, from 2010 onwards, 5 additional therapies have been approved on the basis of showing a survival benefit in phase III studies. These agents include sipuleuceI-T, cabazitaxel, abiraterone, enzalutamide and （most recently） radium-223. Amongst radiopharmaceuticals currently used for advanced prostate cancer （e.g. samarium-153 and strontium-89）, radium-223 possesses several unique properties. As an alpha-emitting compound, the agent produces a high-energy output over a short range, facilitating selective destruction of tissue within the bone in the region of osteoblastic lesions while sparing surrounding normal tissue. The current review will outline biological rationale for radium-223 and also provide an overview of preclinical and clinical development of the agent. Rational sequencing of radium-223 and combinations, in the increasingly complex landscape of mCRPC will be discussed, along with factors influencing clinical implementation.

Herein, we discuss 18-year follow-up data from the Scandinavian ProstateCancer Group-4 （SPCG-4） trial, a randomized study comparing observation and radical prostatectomy （RP） in patients with localized prostate cancer. The results of this study are contrasted with another study employing a similar randomization, the Prostate Cancer Intervention Versus Observation Trial （PIVOT）. We highlight several key differences in study eligibility and enrollment that may account for distinct results, and describe how these datasets impact the complex landscape of therapy for localized prostate cancer.
