Visual recovery after perinatal stroke evidenced by functional and diffusion MRI.

This paper presents some basic theorems giving the structure of cyclic codes of length n over the ring of integers modulo pa and over the p-adic numbers, where p is a prime not dividing n. An especially interesting example is the 2-adic cyclic code of length 7 with generator polynomial X 3 + ,~X 2 + (L I)X -l, where )~ satisfies ~2 _ k + 2 = 0. This is the 2-adic generalization of both the bina...

In this paper, the Peak to mean Envelope Power (PMEPR) of the OFDM codes generated from an 16-QAM constellation is discussed. Maintaining the same level of error correction properties, these codes achieve higher information rate. A new set of 16-QAM Golay sequences having PMEPR bounded up to 3dB is defined. Many recursive structures are found to generate Super Golay sequences. The recursive alg...

In [2], Calderbank and Sloane investigated codes over the p-adics and examined lifts of codes over Zp to Zpe and to the p-adics. They described the [8, 4, 5] 2-adic Hamming code, the [24, 12, 13] 2-adic Golay code, and the [12, 6, 7] 3-adic Golay code. These three codes are all self-dual and MDS. In [3], Dougherty, Kim, and Park gave the weight distribution of the projections of these three cod...

image analysis is an image processing technique that aims to extract features or information from images. image analysis in medicine has a special place because is a basis for disease diagnosis for physicians. electrophoresis is a laboratory separating technique. electrophoresis images are created during the electrophoresis process. serum protein and hemoglobin electrophoresis test are the most...

Complementary sequences were introduced by Marcel Golay [1] in the context of infrared spectrometry. A complementary pair of sequences (CS pair) satis£es the useful property that their out-of-phase aperiodic autocorrelation coef£cients sum to zero [1, 2]. Let a = (a0, a1, . . . , aN−1) be a sequence of length N such that ai ∈ {+1,−1} (we say that a is bi-polar). De£ne the Aperiodic Auto-Correla...

Dihedral Golay sequences are introduced and found for lengths 7,9,15, and 19. Applications include new classes of signed group Hadamard matrices and 19 real Hadamard matrices of orders 2p, p S 4169.
