A New Method for Building Low-Density-Parity-Check Codes

This paper proposes a new method for building low-density-parity-check codes, click here exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal structure is applied to guarantee that parity check bits can be recursively computed with linear calculation c

Nutrition regulates reproductive senescence and terminal investment across the reproductive cycle of a long-lived mammal

Abstract Deterioration in nutritional here condition with aging could reduce reproductive success but coincides with declines in residual reproductive potential, thus invoking opposing expectations for late-life reproduction.Yet, the mechanisms regulating energy accrual and allocation to reproduction and survival throughout the lifetime of long-liv
