"A complex-valued mathematical sequence which, when applied to a signal, gives rise to a new signal of constant amplitude."
It is not clear what is meant by "applied to" here.
Start of a thread on the TUHS mailing list mentioning the japanese project https://github.com/ryomuk/TangNanoDCJ11MEM/tree/main
Memory system and UART implemented on Tang Nano 20K FPGA for DEC DCJ11 PDP-11 Processor.
"Both engineers and computational scientists alike will benefit greatly from having a standard test set for Initial Value Problems (IVPs) which includes documentation of the test problems, experimental results from a number of proven solvers, and Fortran subroutines providing a common interface to the defining problem functions. Engineers will be able to see at a glance which methods will be most effective for their class of problems. Researchers will be able to compare their new methods with the results of existing ones without incurring additional programming workload; they will have a reference with which their colleagues are familiar. This test set tries to fulfill these demands and tries to set a standard for IVP solver testing."

Android 4.1 an app can provide additional keyboard layouts via Key Character Map files. Since then, it’s possible to customize a keyboard layout without root access by installing an app that contains required layout.
"KM3NeT is a research infrastructure housing the next generation neutrino telescopes. Once completed, the telescopes will have detector volumes between megaton and several cubic kilometres of clear sea water. Located in the deepest seas of the Mediterranean, KM3NeT will open a new window on our Universe, but also contribute to the research of the properties of the elusive neutrino particles. With the ARCA telescope, KM3NeT scientists will search for neutrinos from distant astrophysical sources such as supernovae, gamma ray bursters or colliding stars. The ORCA telescope is the instrument for KM3NeT scientists studying neutrino properties exploiting neutrinos generated in the Earth's atmosphere. Arrays of thousands of optical sensors will detect the faint light in the deep sea from charged particles originating from collisions of the neutrinos and the Earth. The facility will also house instrumentation for Earth and Sea sciences for long-term and on-line monitoring of the deep sea environment and the sea bottom at depth of several kilometers."

A source for the statement "The actual number of gates needed to factor a
n-bit number is 72 * n^3; so for 15, it's 4 bits, 4608 gates; not happening any
time soon." would be nice.
