The presence of a visual stimulus not only increases the blood oxygenation level dependent (BOLD) activation in its retinotopic regions in the visual cortex but also suppresses the activation of the nearby regions. Here we investigated whether there are multiple components for such lateral effects by using the m-sequence paradigm to measure the sti...
M-sequences are widely used in communications and positioning systems for synchronization purposes. In these systems, the receiver does not know which sequence is used by the transmitter, this needs to be detected. This paper establishes first a link between the conventional detection theory and the recently developed detection technique relying on...

Let X be a finite set of q elements, and n, K, d be integers. A subset C ⊂ Xn is an (n, K, d) error-correcting code, if #(C) = K and its minimum distance is d. We define an (n, K, d) error-correcting sequence over X as a periodic sequence {ai}i=0,1,... (ai ∈ X) with period K, such that the set of all consecutive n-tuples of this sequence form an (n...

Given an m-sequence, the main factor influencing the least period of the Generalized Self-Shrinking (GSS) sequence is the selection of the linear combining vector G. Based on the calculation of the minimal polynomial of L GSS sequences and the comparison of their degrees, an algorithm for selecting the linear combining vector G is presented, which ...

PurposeIn animal studies intravitreal injection of tetrodotoxin (TTX) results in mfERG waveform changes similar to those observed in glaucoma. As TTX blocks amacrine as well as ganglion cells, there is still a question regarding the underlying cell population responsible for these changes in waveform. In an attempt to assess the contribution of the...
The maximum-length sequences, also called m-sequences, have received a lot of attention since the late 1960s. In terms of linear-feedback shift register (LFSR) synthesis they are usually generated by certain power polynomials over a finite field and in addition are characterized by a low cross correlation and high nonlinearity. We say that such a s...
