TLDR
We introduce a new parameter, the stopping redundancy of Copf, defined as the minimum number of rows in a parity- check matrix H for Copf such that the corresponding stopping distance s attains its largest possible value, namely, s(H)=d. Expand

Rank modulation for flash memories
TLDR
We explore a novel data representation scheme for multi-level flash memory cells, in which a set of n cells stores information in the permutation induced by the different charge levels of the individual cells. Expand

Duplication-correcting codes for data storage in the DNA of living organisms
TLDR
In this paper, we provide error-correcting codes for errors caused by tandem duplications, which create a copy of a block of the sequence and insert it in a tandem manner, i.e., next to the original. Expand

Codes for Asymmetric Limited-Magnitude Errors With Application to Multilevel Flash Memories
TLDR
We propose block codes for asymmetric limited-magnitude errors over q-ary channels when the number of errors is bounded by t and the error magnitudes are bounded by l. Expand

Protective autoimmunity functions by intracranial immunosurveillance to support the mind: The missing link between health and disease
Circulating immune cells support hippocampal neurogenesis, spatial memory, expression of brain-derived neurotrophic factor, and resilience to stress. Nevertheless, considering the immune privilegedExpand
