市场认同上市公司研发支出资本化的价值吗?——基于创业板的经验证据

基于创业板的相关数据,利用改进后的股票价格模型和股票收益率模型,检验资本化研发支出的价值相关性,并对不同种类资本化研发支出(自主研发无形资产和开发支出)对公司价值影响的差异性进行了深入分析。研究发现,资本化研发支出与股票价格和股票收益率不相关,费用化研发支出与股票价格和股票收益率显著负相关;自主研发无形资产与股票价格不相关但与股票收益率显著正相关,开发支出与股票价格和股票收益率不相关。研究结果表明创业板上市公司资本化的研发支出具有一定的价值相关性,但股票市场投资者对创业板的资本化研发支出反应不充分,并且这种疑虑主要是由于开发支出导致的。

3D液晶显示模组不均匀分区背光扫描及其设计方法

随着液晶显示技术的快速发展,3D液晶显示逐渐受到市场和消费者的追捧。在3D液晶电视中,有一类快门式3D显示技术。这种技术通过一定间隔的两台摄像机同时拍摄同一个物体的左右眼两幅画面,然后合成处理后,在显示屏上通过分时显示的方式显示出来,然后搭配与分时频率相同的快门式眼镜,使人的左右眼分别观看到摄像机拍摄到的同一物体画面。由于两幅画面存在视差的不同,人眼即可感受到了立体的影像,实现3D效果显示。为了实现更好的3D显示效果,一般通过扫描背光的方式来对背光系统进行控制。     

Digital body preservation: Technique and applications

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.

Development and implementation of a three-dimensional (3D) printing elective course for health science students

Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.
