Gyrotrons are the only sources used for electron cyclotron resonance heating (ECRH). Past gyrotron experiments have highlighted some instability issues, leading to restricted operating ranges. One major cause is the possible presence of trapped elect

We study on-shell scattering amplitudes for continuous-spin particles. Poincar\'e invariance, little-group $ISO(2)$ covariance, analyticity, and on-shell factorization (unitarity) impose stringent conditions on these amplitudes. We solve them by real

Sparse auto-encoders are useful for extracting low-dimensional representations from high-dimensional data. However, their performance degrades sharply when the input noise at test time differs from the noise employed during training. This limitation

Pulsar timing arrays (PTA) hunt for gravitational waves (GW) by searching for the correlations that GWs induce in the time-of-arrival residuals from different pulsars. If the GW sources are of astrophysical origin, then they are located at discrete p

Context. The recent detection of nitrogen-enhanced, metal-poor galaxies at high redshift by the James Webb Space Telescope has sparked renewed interest in exploring the chemical evolution of carbon, nitrogen, and oxygen (the CNO elements) at early ti

We present several algorithms for evaluating point containment in constructive solid geometry (CSG) trees with unbounded primitives. Three algorithms are presented based on postfix, prefix, and infix notations of the CSG binary expression tree. We sh

Pulsar timing arrays (PTAs) have made tremendous progress and are now showing strong evidence for the gravitational-wave background (GWB). Further probing the origin and characteristics of the GWB will require more generalized analysis techniques. Ba

We review approaches to statistical inference based on randomization. Permutation tests are treated as an important special case. Under a certain group invariance property, referred to as the ``randomization hypothesis,'' randomization tests achieve

In this work we compute the rates and numbers of different types of stars and phenomena (SNe, novae, white dwarfs, merging neutron stars, black holes) that contributed to the chemical composition of the Solar System. Stars die and restore the newly f

In this paper, an optimized version of classical Bombelli's algorithm for computing integer square roots is presented. In particular, floating-point arithmetic is used to compute the initial guess of each digit of the root, following similar ideas to
