    1. We're a new division of Midjourney focused on a radical new vision for healthcare using a totally new form of medical imaging we call "Ultrasonic CT" or simply "the full body ultrasound"

      一家以AI图像生成闻名的公司突然宣布进入医疗成像硬件领域——这个跨界本身就值得停下来想一想。Midjourney的核心能力是图像理解和生成,而医学影像从根本上也是「从信号重建图像」的问题。超声CT需要从大量声波传感器数据中重建3D图像,这与AI图像处理存在一定技术相关性。但从软件到制造精密医疗硬件的跨度仍然巨大。这个宣告没有任何技术细节、没有论文引用、没有FDA状态——是一个需要大量后续信息才能评估的方向性声明。

    1. Aortic dissection typically presents acutely with sudden, severe tearing chest or back pain, often described as lancinating in quality. [5-6] Approximately 50% of patients with thoracic aortic aneurysm may progress to dissection without timely intervention. [5] In contrast, thoracic aortic aneurysm is usually asymptomatic and discovered incidentally during physical examination or imaging for other indications. [5]

    1. Scavenger hunts, bingo, dice games, Connect Four and Scrabble have been around for decades and can be adapted for classroom learning

      These can be adapted in the classroom to promote critical thinking and by encouraging students to problem-solve, make strategic decisions, and apply prior knowledge.

    1. なお、べき乗は 1.3 節で扱った ** 演算子でも計算できますが、組み込み関数 pow を用いたほうが高速に計算できます。 また、余りは pow(a,b) % mod のように後から計算しても同じ結果になりますが、pow(a,b) の値が非常に大きくなる場合は pow(a,b,mod) のほうが高速に計算できます。 競技プログラミングにおいては pow 関数を使うことが必須であるケースが多いため覚えておきましょう。

    1. The term computational science, and its associated term computational thinking, came into wide use during the 1980s. In 1982, theoretical physicist Kenneth Wilson received a Nobel Prize in physics for developing computational models that produced startling new discoveries about phase changes in materials.
    2. Nearly everybody had something to gain. Experimenters looked to computers for data analysis—sifting through large data sets for statistical patterns. Theoreticians looked to them for calculating the equations of mathematical models.
