做光学设计的同行都懂，好镜头是“调”出来的，也是“等”出来的。Zemax里反复改曲率和厚度，Lumerical里扫描周期单元的相位响应，一个参数组合跑下来，工作站转一整天是常态。更别提无透镜成像的重建调参、叠层成像的扫描校正，每一步都靠手动调试和 ...

The spin-off company ParityQC has implemented the largest quantum Fourier transform ever reported using an IBM quantum computer, thereby setting a new milestone on the path toward the industrial ...

The Christensen Arms Ridgeline FFT is an ultralight precision rifle weighing just 5.45 pounds, built with a carbon-fiber wrapped barrel and Flash Forged Technology stock. This rifle excels for ...

Abstract: Clear and reliable images are essential in areas such as medical scans, satellite imaging, and automated inspections, where even small details matter. In this paper, we present a simple but ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

An expert discusses that while the liso-cel trial did not show a statistically significant overall survival benefit—likely due to its small sample size and crossover design—it still demonstrated ...

Abstract: Fourier Transform (FT) is an important signal processing technique that translates time-domain signals to frequency-domain forms. It is widely used in several applications, including 5G ...

kokkos-fft provides a unified, performance-portable interface for Fast Fourier Transforms (FFTs) within the Kokkos ecosystem (C. Trott et al., 2021). It seamlessly integrates with leading local FFT ...
