Microcode inside the Intel 8087 floating-point chip: register exchange

In 1980, Intel introduced the 8087 floating-point chip, a co-processor that made floating-point operations up to 100 times faster. This chip was highly influential, and today most processors use the floating-point standard introduced by the 8087. The 8087 uses complicated algorithms to accurately compute functions such as square roots, tangents, and exponentials.

Complex-phase stochastic modeling of mitochondrial heteroplasmy

Mitochondrial heteroplasmy the coexistence of both wild-type and mutant copies of mitochondrial DNA ( mtDNA ) within a cell is a key factor in the pathogenesis of mitochondrial diseases. Classical approaches, which rely solely on the scalar fraction of mutant DNA, fail to fully account for threshold effects, the stochastic nature of heteroplasmy dynamics , and tissue specificity. The aim of the work is to construct a complex stochastic model of heteroplasmy dynamics , which for the first...

Closed-form linear moments of the two-dimensional angular central Gaussian distribution

arXiv:2605.31536v1 Announce Type: cross Abstract: The polar-angle marginal of a centred bivariate Gaussian distribution, obtained after integrating out the radial coordinate, gives the two-dimensional angular central Gaussian (ACG) distribution of Tyler. While its trigonometric and vector-valued moments have been studied in detail, to our knowledge there are no explicit closed-form expressions for the \emph{linear} moments $\mathbf{E}[\theta]$ and $\mathbf{E}[\theta^{2}]$ on the natural...
