Distribution of Roots of Polynomial Congruences [PDF]
International Journal of Mathematics and Mathematical Sciences, 2007 For a primep, we obtain an upper bound on the discrepancy of fractionsr/p, whererruns through all of roots modulopof all monic univariate polynomials of degreedwhose vector of coefficients belongs to ad-dimensional boxℬ. The bound is nontrivial starting with boxesℬof size|ℬ|≥pd/2+ɛfor any fixedɛ<0and sufficiently largep.

Root Vertex Valency Distributions of Rooted Maps and Rooted Triangulations
European Journal of Combinatorics, 1994 We obtain the asymptotic distributions of root vertex valencies for rooted maps and rooted triangulations on general surfaces. We show that the asymptotic distributions are independent of the surface.

Belowground interactions differ between sympatric desert shrubs under water stress
Ecology and Evolution, 2020 Understanding the relationships among species is central to ecological research; however, many knowledge gaps remain regarding how desert plant species interact. In the present study, we assessed the effect of rainfall on the belowground interactions and

Distribution of Expansins in Graviresponding Maize Roots [PDF]
Plant and Cell Physiology, 2000 To test if expansins, wall loosening proteins that disrupt binding between microfibrils and cell wall matrix, participate in the differential elongation of graviresponding roots, Zea mays L. cv. Merit roots were gravistimulated and used for immunolocalization with anti-expansin. Western blots showed cross-reaction with two proteins of maize, one of the

The dynamics of root meristem distribution in the soil [PDF]
Plant, Cell & Environment, 2010 Plants must develop efficient root architectures to secure access to nutrients and water in soil. This is achieved during plant development through a series of expansion and branching processes, mostly in the proximity of root apical meristems, where the plant senses the environment and explores immediate regions of the soil.

Root Growth of Hordeum vulgare and Vicia faba in the Biopore Sheath
Agriculture, 2020 Biopores provide nutrients from root debris and earthworm casts. Inside large biopores, root function is limited due to the lack of root–soil contact. However, the immediate surroundings of biopores may hold a key function as “hotspots” for root growth ...
