In order to estimate the spatial covariance structure of sea surface temperature (SST) using advanced very high resolution radiometer (AVHRR) satellite data, autocorrelation induced by the sensor itself must be determined and then removed before the correlative properties of SST per se can be found. Sensor-induced autocorrelation arises from (1) partially redundant sampling and (2) a nonideal i...

A computational model of human memory for serial order is described (OSCillator-based Associative Recall [OSCAR]). In the model, successive list items become associated to successive states of a dynamic learning-context signal. Retrieval involves reinstatement of the learning context, successive states of which cue successive recalls. The model provides an integrated account of both item memory...

The second of two targets (T2) embedded in a rapid serial visual presentation (RSVSVP) is often missed even though the first (T1) is correctly reported (attentional blink). The rate of correct T2 identification is quite high, however, when T2 comes immediately after T1 (lag-1 sparing). This study investigated whether and how non-target items induce lag-1 sparing. One T1 and two T2s comprising l...

BACKGROUND The serial 100-7s subtraction, an item on the Mini-Mental State Examination (MMSE), is well known for being difficult for uneducated people. Therefore, we investigated into alternative serial subtractions for serial 100-7s subtraction in uneducated people. METHODS One hundred sixty-nine subjects were enrolled by neurologic or neuropsychiatric out-patient clinics in 4 university med...

The main objective of this study gears towards evaluating monetary policy transmission paths and money supply in Sub- Saharan Africa: evidence from Nigeria Ghana from1981- 2018. Central Bank Nigeria, World Bank, Development Indicator 2018 furnished us with the data used for analysis. This explored three different channels: interest rate, credit asset pricing channels these variables were regres...

This paper provides an overview of recent results for relay-delay systems. In a first section, simple examples illustrate the problems induced by delays in the synthesis of sliding mode controllers. Then, a brief overview of the existing results shows the present advances and limits in this domain. The last parts of the paper are devoted to new results: first, for systems with state delay, then...

Precipitation patterns are influenced by many factors, such as global atmospheric circulations to name but one. Precipitation patterns in Iran have always had great fluctuations even in a smaller scale like the Alburz Mountain Range. The present research has tried to find the relationship between global atmospheric patterns and the pervasive precipitation ones in Alburz. For doing so, 17 climat...

We discuss the limiting behavior of the serial correlation coefficient in mildly explosive autoregression, where the error sequence is in the domain of attraction of an α–stable law, α ∈ (0, 2]. Therein, the autoregressive coefficient ρ = ρn > 1 is assumed to satisfy the condition ρn → 1 such that n(ρn − 1) → ∞ as n → ∞. In contrast to the vast majority of existing literature in the area, no sp...
