European Journal of Education, Volume 61, Issue 3, September 2026.ABSTRACT Foreign Language Enjoyment has received increasing attention in second language acquisition due to its role in fostering engagement and communication. Although previous research has often treated enjoyment as a relatively stable trait, perspectives informed by Complex Dynamic Systems Theory (CDST) suggest that emotions are dynamic, non‐ergodic,

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

On Ergodic Capacity of Spectrum-Sharing Systems in Fading Channels
IEICE Transactions on Communications, 2009 In spectrum-sharing systems where the secondary user (SU) opportunistically accesses the primary user (PU)'s licensed channel, the SU should satisfy both the transmit power constraint of the SU transmitter and the received power constraint at the PU receiver. This letter studies the ergodic capacity of spectrum-sharing systems in fading channels.

Earthquake Spectra, Volume 42, Issue 3, August 2026.With the recent increases in measured ground motion records for large earthquakes, most notably the 2023 M7.8 Pazarcik earthquake in Türkiye, the potential for pervasive high velocity fault rupture propagation over an extensive fault length has been observed.

Inference on Common Trends in a Cointegrated Nonlinear SVAR
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 658-676, August 2026.ABSTRACT We consider the problem of performing inference on the number of common stochastic trends when data is generated by a cointegrated CKSVAR (a two‐regime, piecewise affine SVAR; Mavroeidis, 2021), using a modified version of the Breitung (2002) multivariate variance ratio test that is robust to the presence of nonlinear cointegration (of a known

Large‐Dimensional Cointegrated Threshold Factor Models: The Global Term Structure of Interest Rates
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 677-689, August 2026.ABSTRACT In this paper we extend the two‐level factor model to account for cointegration between group‐specific factors in large datasets. We propose two nonlinear specifications: (i) a threshold vector error correction model (VECM) that allows for asymmetric adjustment across regimes; and (ii) a band VECM that captures state‐dependent adjustment which

An EZ${\mathcal {E}\mathcal {Z}}$‐structure for the mapping class group
Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.Abstract We construct a boundary for the mapping class group Mod(S)${\rm Mod}(S)$ of a surface S$S$ of finite type. The action of Mod(S)${\rm Mod}(S)$ on this boundary is minimal, strongly proximal and topologically free. The boundary is the boundary of an EZ${\mathcal {E}\mathcal {Z}}$‐structure for Mod(S)${\rm Mod}(S)$.

On the Performance of Multihop Heterodyne FSO Systems With Pointing Errors
IEEE Photonics Journal, 2015 This paper reports the end-to-end performance analysis of a multihop free-space optical system with amplify-and-forward (AF) channel-state-information (CSI)-assisted or fixed-gain relays using heterodyne detection over Gamma-Gamma turbulence fading with ...
