In 1953, Pjateckii[breve]-S[breve]apiro has proved that there are infinitely many primes of the form [n^c] for 1 [less than] c [less than] {12\over11} (with an asymptotic result). This range, which measures our progress in the technique of exponential sums, has been improved by...

americanus, D. pulex, P. japonicus and P. trituberculatus, there appears to be a 5-bp overlap between the last and the termination codon of COI and the tRNALeu(UUR) gene (Figure 2), as proposed for P. monodon (Wilson et al, 2000) and T. cancriformis (Umetsu et al, 2002). ...
Study on the CNC internal gear form grinding technology Gear grinding is widely used for finishing gears with hard face. Gear form grinding has many advantages over gear generation grinding. The form grinding ac... X Ren,J Su,X Deng - IEEE 被引量: 8发表: 2009年 A Study on a High-Spee...

XBR Honda motor as found in the old WKs, the Mash and many other Chinese 400-cc bikes (under various brands) including the now-discounted SWMs 440s. The NCs are a cut above that and in 2017 Zongshen entered five NC-engined bikes in the Dakar. All DNF’d, but mostly due to crashes...
By applying the theory in a previous paper, the authors proposed a method to calculate the exact profile of a form grinding wheel for finishing a helical gear with an arbitrary tooth profile. Using this method, they calculated the exact wheel profile which can produce an involute tooth profile...

This SoC is very new, but there's currently (2023-08) an [effort to integrate the RK3588 SoC into mainline](https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md). This means it'll probably be easier to get things like ...
