Making (Non)Sense: On Ruth Ozeki\u27s A Tale for the Time Being

This essay investigates the knowledge produced around Ruth Ozeki’s novel A Tale for the Time Being through a discussion of its marketing processes and its reception, as well as through textual analysis. I first draw upon Sau-ling Wong’s observations about the problem of a US-centric referential framework in the internationalization of Asian American studies to examine a Western-centric framing in the marketing strategies of the US/Canada and the UK editions of Ozeki’s novel. Next, I turn to an examination of how reviews and selected readers’ responses to Ozeki’s novel show an at-times incoherent process of making sense of this text. In the latter part of the paper, I analyze the parallel depictions of Fukushima and Cortes Island, Ruth’s dreams, and Haruki #1’s diary in Ozeki’s novel. Attending to how Ozeki’s narratives destabilize the process of making sense, I argue that the novel is neither easy to read nor as transparent as the marketing strategies and reviews and readers’ responses suggest. The difficulties of making sense represented in A Tale for the Time Being thereby have the potential to intervene in a Western-centric, posivistic reading of the Asian other, challenging us to rethink the analytic frameworks we bring to bear while reading Asian American literary texts

Ultrafast processing of pixel detector data with machine learning frameworks

Modern photon science performed at high repetition rate free-electron laser (FEL) facilities and beyond relies on 2D pixel detectors operating at increasing frequencies (towards 100 kHz at LCLS-II) and producing rapidly increasing amounts of data (towards TB/s). This data must be rapidly stored for offline analysis and summarized in real time. While at LCLS all raw data has been stored, at LCLS-II this would lead to a prohibitive cost; instead, enabling real time processing of pixel detector raw data allows reducing the size and cost of online processing, offline processing and storage by orders of magnitude while preserving full photon information, by taking advantage of the compressibility of sparse data typical for LCLS-II applications. We investigated if recent developments in machine learning are useful in data processing for high speed pixel detectors and found that typical deep learning models and autoencoder architectures failed to yield useful noise reduction while preserving full photon information, presumably because of the very different statistics and feature sets between computer vision and radiation imaging. However, we redesigned in Tensorflow mathematically equivalent versions of the state-of-the-art, "classical" algorithms used at LCLS. The novel Tensorflow models resulted in elegant, compact and hardware agnostic code, gaining 1 to 2 orders of magnitude faster processing on an inexpensive consumer GPU, reducing by 3 orders of magnitude the projected cost of online analysis at LCLS-II. Computer vision a decade ago was dominated by hand-crafted filters; their structure inspired the deep learning revolution resulting in modern deep convolutional networks; similarly, our novel Tensorflow filters provide inspiration for designing future deep learning architectures for ultrafast and efficient processing and classification of pixel detector images at FEL facilities.Comment: 9 pages, 9 figure
