Facial expression and emotion recognition from thermal infrared images has attracted more and more attentions in recent years. However, the features adopted in current work are either temperature statistical parameters extracted from the facial regions of interest or several hand-crafted features that are commonly used in visible spectrum. Till now there are no image features specially designed for thermal infrared images. In this paper, we propose using the deep Boltzmann machine to learn thermal features for emotion recognition from thermal infrared facial images. First, the face is located and normalized from the thermal infrared im- ages. Then, a deep Boltzmann machine model composed of two layers is trained. The parameters of the deep Boltzmann machine model are further fine-tuned for emotion recognition after pre-tralning of feature learning. Comparative experimental results on the NVIE database demonstrate that our approach outperforms other approaches using temperature statistic features or hand-crafted features borrowed from visible domain. The learned features from the forehead, eye, and mouth are more effective for discriminating valence dimension of emotion than other facial areas. In addition, our study shows that adding unlabeled data from other database during training can also improve feature learning performance.

For many supervised learning applications, addi- tional information, besides the labels, is often available dur- ing training, but not available during testing. Such additional information, referred to the privileged information, can be exploited during training to construct a better classifier. In this paper, we propose a Bayesian network （BN） approach for learning with privileged information. We propose to in- corporate the privileged information through a three-node BN. We further mathematically evaluate different topologies of the three-node BN and identify those structures, through which the privileged information can benefit the classifica- tion. Experimental results on handwritten digit recognition, spontaneous versus posed expression recognition, and gender recognition demonstrate the effectiveness of our approach.

经济文本中有关经济学相关理论、行为及现象对于普通读者而言往往过于复杂和抽象,作者通常会采用隐喻方案来破解这些难题,而隐喻翻译准确与否直接关系到经济信息的获取和读者的阅读体验,因此英文财经文本中大量的隐喻成了译者翻译过程中的一大难关。本文以此为出发点,旨在以分级显性意义假说为理论框架,基于包括95篇经济文本的自建环球网财经新闻编译语料库,从凸显性的词汇通达和认知推理两个工作维度探讨英文财经文本中隐喻翻译的宏观策略和微观方法,希冀对日后经济文本的英汉翻译有所裨益。

NAK80是一种预硬塑胶模具钢,对应国产牌号1Ni3MnCuMoAl,因其是预硬状态交货,不再需热处理,加之良好的抛光性和雕饰性,在塑胶方向得到广泛应用。而钢的纯净度直接决定了该钢的抛光性,研究发现NAK80模具钢中夹杂物主要以AlN为主,若钢中含有微量的Ti,TiN会优先析出,AlN数量会大大减少。因该钢的AlN在固液两相区析出,电渣重熔对去除AlN夹杂物效果微乎其微,随着熔速的增快,AlN尺寸反而有长大的趋势,而在真空自耗重熔情况下,AlN会发生分解,AlN夹杂物也随之减少。本文主要研究分析NAK80钢中AlN夹杂物的形态、尺寸及形成方式,以及在经过电渣及真空自耗二次重熔后夹杂物的变化,和一些过程参数对AlN夹杂物的影响。

射血分数保留的心力衰竭(HFpEF)现已成为心力衰竭的主要类型,其临床症状具有高度异质性,预后较差,且发病率仍在不断增长。受多种危险因素影响,HFpEF的发病机制复杂,病理生理学机制尚未得到阐明,目前仍缺少有效的治疗手段。近年来,学者们发现线粒体功能障碍是多种疾病发生、发展的潜在影响因素。随着研究不断深入,线粒体功能障碍在HFpEF发生发展中的重要作用开始得到认可,靶向线粒体功能障碍有可能成为制订HFpEF治疗策略的突破点之一。本文综述线粒体能量代谢、产生活性氧簇、线粒体自噬、调节钙稳态等相关功能在HFpEF病理过程中的研究进展,简述HFpEF的治疗现况,为寻找药物治疗新靶点、减轻HFpEF的临床症状提供新思路。
