Classically, formal orthogonal polynomials are studied with respect to a linear functional, which gives rise to a moment matrix with a Hankel structure. Moreover, in most situations, the moment matrix is supposed to be strongly regular. This implies a number of algebraic properties which are well known, like for example the existence of a three-term recurrence relation (characterised by a tridi...

Low-phosphorus (LP) stress is a global problem for maize production and has been exacerbated by breeding activities that have reduced the genetic diversity of maize. Although LP tolerance in maize has been previously evaluated, the evaluations were generally performed with only a small number of accessions or with samples collected from a limited area. In this research, 826 maize accessions (in...

Cold tolerance is a key determinant of insect distribution and abundance, and thermal acclimation can strongly influence organismal stress tolerance phenotypes, particularly in small ectotherms like Drosophila. However, there is limited understanding of the molecular and biochemical mechanisms that confer such impressive plasticity. Here, we use high-throughput mRNA sequencing (RNA-seq) and liq...

Although freedom of speech is a Constitutionally protected and widely endorsed value, political tolerance research finds that people are less willing to protect speech they dislike than speech they like (Gibson, 2006). Research also suggests liberal-conservative differences in political tolerance (Davis & Silver, 2004). We measured U.S. citizens’ political tolerance for speech acts, while manip...

Significance Coping with UV-B is crucial for plant survival in sunlight. The photoreceptor UVR8 regulates gene expression associated photomorphogenesis, acclimation, and stress tolerance. photon reception by homodimers results monomerization, followed interaction the key signaling protein COP1. We have discovered a hypersensitive that confers strongly enhanced tolerance generated variant based ...
