Dual Role of an mps-2/KCNE-Dependent Pathway in Long-Term Memory and Age-Dependent Memory Decline [PDF]
Current Biology, 2021 Activity-dependent persistent changes in neuronal intrinsic excitability and synaptic strength are underlying learning and memory. Voltage-gated potassium (Kv) channels are potential regulators of memory and may be linked to age-dependent neuronal disfunction.

Value-at-risk and expected shortfall: a dual long memory framework
Global Business and Economics Review, 2014In this article, we use the dual long memory properties to assess the value-at-risk and expected shortfall for the Argentinean stock market under both short and long daily trading positions. We attempt to show whether considering for long memory properties in both, the returns and volatility, volatility asymmetry and fat-tails could provide more ...

Risks in Major Cryptocurrency Markets: Modeling the Dual Long Memory Property and Structural Breaks
Sustainability, 2023 This study estimates the effects of the dual long memory property and structural breaks on the persistence level of six major cryptocurrency markets. We apply the Bai and Perron structural break test, Inclán and Tiao’s iterated cumulative sum of squares (ICSS) algorithm, and the fractionally integrated generalized autoregressive conditional ...

A Dual Long Short-Term Memory Model in Forecasting the Number of COVID-19 Infections
Electronics (Switzerland), 2023 Since the outbreak of the Coronavirus Disease 2019 (COVID-19), the spread of the epidemic has been a major international public health issue. Hence, various forecasting models have been used to predict the infectious spread of the disease. In general, forecasting problems often involve prediction accuracy decreasing as the horizon increases.

Dual trace theory and the consolidation of long-term memory
Journal of Mathematical Psychology, 1971Abstract Retention functions were determined for four S s for recognition memory of letters at 14 different delays from 3 sec to 5 min and two levels of storage load (1 and 6 letter lists), the retention interval being filled with backward counting.

On the inflation-uncertainty hypothesis in the USA, Japan and the UK: a dual long memory approach
Japan and the World Economy, 2005Abstract We use parametric models of long memory in both the conditional mean and the conditional variance of inflation and monthly data in the USA, Japan and the UK for the period 1962–2001 to examine the relationship between inflation and inflation-uncertainty.

Frontiers of Economics in China, 2008
This paper uses the ARFIMA-FIGARCH model to investigate the China’s monthly inflation rate from January 1983 to October 2005. It is found that both first moment and second moment of inflation have remarkable long memory, indicating the existence of long memory properties in both inflation level and inflation uncertainty.

Dual long-memory, structural breaks and the link between turnover and the range-based volatility
Journal of Empirical Finance, 2009Abstract This paper investigates the issue of temporal ordering of the range-based volatility and turnover volume in the Korean market for the period 1995–2005. We examine the dynamics of the two variables and their respective uncertainties using a bivariate dual long-memory model.
