Diljit Dosanjh Highlights Narrative Control Discussion As Punjab 95 Remains Stalled By CBFC_我的网站
一 | 记者24日从兰州大学获悉，该校物理科学与技术学院田永辉教授团队在光学数字计算领域取得重要进展。
二 | The debate around cinematic narratives and representation has taken a personal turn as Diljit Dosanjh recently shared a hard-hitting post on his Instagram stories. He shared a report highlighting the stark contrast between the reception of mainstream patriotic films and the ongoing struggle of his long-delayed biopic, Punjab 95. The post shared by Diljit draws a direct comparison between how certain roles are celebrated versus others that face hurdles. It points out that while Diljit receives widespread acclaim for his participation in high-profile patriotic projects like Border 2, his work on the biopic of human rights defender Jaswant Singh Khalra remains in a state of limbo. The shared content notes that Punjab 95 has been stuck with the CBFC (Central Board of Film Certification) for three years. This delay stands in contrast to the rapid success of other contemporary releases, such as Dhurandhar: The Revenge, which the post mentions is being celebrated even as Punjab 95 continues its battle with the censor board. Punjab 95, directed by Honey Trehan, delves into the life of Jaswant Singh Khalra and his investigations into sensitive historical events in Punjab. The film has reportedly faced demands for extensive cuts and changes, preventing its domestic release for almost 36 months. The post suggests a perceived disparity in how the film industry and regulatory bodies treat different types of stories. While films that align with established nationalistic themes often find a smooth path to the audience, biographical stories that explore complex human rights issues or historical grievances seem to face a much more rigorous and prolonged screening process. By sharing this specific critique, Diljit Dosanjh aligned himself with the conversation regarding creative freedom and the importance of telling diverse stories. For now, the contrast between the celebrated mainstream cinema and the stalled biopic of Jaswant Singh Khalra continues to spark a debate about the future of storytelling in Indian cinema.

三 | 该团队研制出一种可重构光学算术逻辑单元芯片，将多种逻辑与算术运算集成于同一硬件平台。相关成果发表于国际权威期刊《自然·通讯》。 随着人工智能与数据密集型应用对高速、低时延计算需求的激增，传统电子集成电路正面临摩尔定律放缓、互连带宽受限和功耗持续上升等挑战。集成光子技术凭借大带宽、高速并行处理和低传输时延等优势，为突破电子计算瓶颈提供了重要的技术路径。 基于这一背景，研究团队依托成熟的硅光子集成平台，利用微环调制器体积小、调制速度快、功耗低且易于电控重构的特点，研制出可实现多种逻辑与算术功能动态切换的光学数字计算芯片。团队通过级联微环构建基本逻辑单元，实现了NOT、AND、OR、XOR和XNOR等多种逻辑运算；同时引入波长维度并行处理不同二进制位，使同一硬件架构能够动态切换为2比特加法器、减法器和数值比较器，无需重新设计芯片结构。 芯片基于220纳米硅绝缘体平台制备，每个微环集成载流子耗尽型高速电光调制结构和热调谐单元，可分别完成高速数据加载与工作波长校准。实验结果表明，该系统在20Gbit/s速率下实现了基本逻辑运算及算术功能，计算密度达到528Gbit/s2，能效达12.36fJ/bit。 在此基础上，团队完成了高速数据加密与解密、医学图像水印嵌入和图像差异增强等应用验证，展示了该架构从基础逻辑器件向多功能光学数字计算系统扩展的能力。 田永辉表示，该工作为构建高密度、低功耗、可重构的光子算术逻辑处理芯片提供了新的实现路径，也为光学数字计算在高速信息处理和片上智能计算中的应用奠定了器件基础。（记者颉满斌 通讯员余若怡）。
