We studied the condensate mass of QCD vacuum through the duality approach via dilaton wall back ground in the presence of the parameter c,which represents the condensation in a holographic set up.First,from Wilson line calculation,we found mo2 (i.e.,the condensate parameter in mixed non-local condensation),whose behavior mimics that of QCD.The value of m20 that we found by this approach is in agreement with QCD data.Second,we considered the produced mass m via the Schwinger effect mechanism in the presence of the parameter c.We show that vacuum condensation generally contributes the mass dominantly and that the produced mass via Schwinger effect is suppressed by m0.

赛博空间是在互联网技术、电脑游戏、赛博格等概念下所催生出来的一种关于未来世界空间的想象。赛博朋克电影中,赛博空间作为一种复杂的文化表达,蕴含着对人与科技关系的思考。文章主要以《银翼杀手》《银翼杀手2049》《黑客帝国》《攻壳机动队》《头号玩家》《阿丽塔:战斗天使》《人工智能》《机械姬》这几部比较有代表性的赛博朋克电影为研究对象,从物质空间、精神空间、权力空间三个角度分析赛博朋克电影中的赛博空间建构,探索其背后的社会文化意义。

数字技术是传统文化创新的催化剂。在“互联网+”的背景下,故宫博物院除了在实体文创产品上发力,还利用数字技术、互联网手段,通过文化与科技的创新融合,衍生出一系列传播面宽、受众面广、趣味性强、具有情感体验的多维度跨界融合的数字文创产品,极大地拓展了文创产品的领域和边界。文章以故宫博物院为主体,对“互联网+”背景下故宫文创数字化建设和发展路径进行探讨。
电影《美丽心灵》的剧本源自于《名利场》杂志上的一篇文章。电影制作人布莱恩在该杂志上了解了一位数学天才的故事,他被这个故事中的人性光辉所打动,于是在获得这个故事的改编拍摄权之后直接邀请著名编剧阿瓦奇·高斯曼执笔,同时邀请该数学天才本人到拍摄现场进行指导,最终完美地表达了数学天才约翰·纳什患有精神分裂症之后如何研究博弈论和微分几何学领域并获得诺贝奖经济学奖的故事。
《辛德勒的名单》自1993年上映以来,斩获多项重量级大奖。其中电影音乐的运用更是炉火纯青,甚至为这部黑白影片增色不少。在反复观看电影之后,笔者发现,在《辛德勒的名单》中音乐可以对影片色彩起到至关重要的填补作用。
