Unemployment Rates Forecasts – Unobserved Component Models Versus SARIMA Models In Central And Eastern European Countries [PDF]

, 2017
In this paper we compare the accuracy of unemployment rates forecasts of eight Central and Eastern European countries. The unobserved component models and seasonal ARIMA models are used within a rolling short-term forecast experiment as an out-of-sample ...

Successive Orthorhombic Distortions in Kagome Metals by Molecular Orbital Formation

Advanced Materials, EarlyView.
Orthorhombic distortions in kagome metals break the symmetry required for exotic charge order. Synchrotron X‐ray diffraction of NdRu3Si2 reveals successive orthorhombic transitions driven by molecular orbital formation between kagome layers. The frustrated kagome lattice hosts degenerate patterns of kagome dimers whose short‐range correlations produce ...
