Long-lived driven solid-state quantum memory
, 2012 We investigate the performance of inhomogeneously broadened spin ensembles as quantum memories under continuous dynamical decoupling. The role of the continuous driving field is two-fold: first, it decouples individual spins from magnetic noise; second ...

Assessing the involvement of long-term memory in working memory
Psychonomic Bulletin & ReviewAbstract Complex span tasks are working memory (WM) tasks in which participants maintain series of items (e.g., letters) for further serial recall while performing a concurrent task (e.g., parity judgement on digits). It has been shown that even pushing the demand of this concurrent task at its individual limits strongly reduces, but ...

Multi-Timescale Recurrent Neural Networks Beat Rough Volatility for Intraday Volatility Prediction
RisksWe extend recurrent neural networks to include several flexible timescales for each dimension of their output, which mechanically improves their abilities to account for processes with long memory or highly disparate timescales. We compare the ability of

Spurious Long Memory in Commodity Futures: Implications for Agribusiness Option Pricing [PDF]
Long memory, and more precisely fractionally integration, has been put forward as an explanation for the persistence of shocks in a number of economic time series data as well as to reconcile misleading findings of unit roots in data that should be ...

Modeling Long Memory in REITs [PDF]
One stylized feature of financial volatility impacting the modeling process is long memory. This paper examines long memory for alternative risk measures, observed absolute and squared returns for Daily REITs and compares the findings for a market equity
