SIDE models realistic biomolecular transition paths
—
in ChemistryWhat the study found The study found that SIDE, a Stochastic Integro-Differential Equation approach based on the Langevin bridge formalism, can generate realistic transition paths between different conformations of large biomolecular systems. In the authors' description, it produces smooth, low-energy trajectories and often recovers experimentally supported intermediate states. Why the authors say this matters The…
Hermite process distributions are shown to admit densities
—
in MathematicsWhat the study found Finite-dimensional distributions of Hermite processes of order q ge 1 with self-similarity parameter H in (1/2, 1) are shown to admit a density with respect to Lebesgue measure. This result is stated for any distinct times t_1, …, t_n. Why the authors say this matters The authors note that the Gaussian…
Infinite-mean durations found in five cryptocurrency ETFs
Asymptotic theory for integrated autoregressive conditional duration models reveals infinite-mean trading intervals in cryptocurrency ETFs, requiring new inference methods.
Unweighted HJM setting supports yield-curve modeling with negative yields
New approach to Heath–Jarrow–Morton framework using unweighted function spaces and functional PCA, enabling better yield curve modeling with support for negative interest rates.
