On even codes

open access: yesDiscrete Mathematics, 1991
Even self-orthogonal codes over \(GF(2^ m)\) are introduced. If \(GF(2^ m)\) is identified with \((GF(2))^ m\) using a self-complementary basis, such codes become binary codes in which all weights are multiples of four. Extended Reed-Solomon codes of rate \(\leq 1/2\) turn out to be even.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Application of Landscape Ecology Indices in Monitoring and Assessing Desertification (Case Study: Omrani Area of Gonabad) [PDF]

open access: yesجغرافیا و پایداری محیط, 2018
Desertification is one of the most important degenerative phenomena in many arid and semi-arid regions. Climate change and human activities have led to the increase of desertification and desert development in these areas.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

On the diversity‐based measures of equalness and evenness

open access: yesMethods in Ecology and Evolution
While the notion of evenness is generally undisputed, its opposite, unevenness, is vague. Conventionally, evenness is understood to decrease, and thus unevenness to increase, as the effective number of types of positive frequency tends towards one while ...
