abstract = {{Modern wireless communication systems are expected to provide improved
latency and reliability. To meet these expectations, a short packet length is
needed, which makes the first-order Shannon rate an inaccurate performance
metric for such communication systems. A more accurate approximation of the
achievable rates of finite-block-length (FBL) coding regimes is known as the
normal approximation (NA). It is therefore of substantial interest to study the
optimization of the FBL rate in multi-user multiple-input multiple-output
(MIMO) systems, in which each user may transmit and/or receive multiple data
streams. Hence, we formulate a general optimization problem for improving the
spectral and energy efficiency of multi-user MIMO-aided ultra-reliable
low-latency communication (URLLC) systems, which are assisted by reconfigurable
intelligent surfaces (RISs). We show that a RIS is capable of substantially
improving the performance of multi-user MIMO-aided URLLC systems. Moreover, the
benefits of RIS increase as the packet length and/or the tolerable bit error
rate are reduced. This reveals that RISs can be even more beneficial in URLLC
systems for improving the FBL rates than in conventional systems approaching
Shannon rates.}},

stochastic differential equations on reproducing kernel Hilbert spaces (RKHS).
Our focus is on the estimation error if the data are collected from long-term
ergodic simulations. We derive both an exact expression for the variance of the
kernel cross-covariance operator, measured in the Hilbert-Schmidt norm, and
probabilistic bounds for the finite-data estimation error. Moreover, we derive
a bound on the prediction error of observables in the RKHS using a finite
Mercer series expansion. Further, assuming Koopman-invariance of the RKHS, we
provide bounds on the full approximation error. Numerical experiments using the
Ornstein-Uhlenbeck process illustrate our results.}},
