Tonal prisms: iterated quantization in chromatic tonality and Ravel's 'Ondine' [PDF]
, 2013 The mathematics of second-order maximal evenness has far-reaching potential for application in music analysis. One of its assets is its foundation in an inherently continuous conception of pitch, a feature it shares with voice-leading geometries.

Lignin engineering in field-grown poplar trees affects the endosphere bacterial microbiome [PDF]
, 2016 Cinnamoyl-CoA reductase (CCR), an enzyme central to the lignin bio-synthetic pathway, represents a promising biotechnological target to reduce lignin levels and to improve the commercial viability of lignocellulosic biomass. However, silencing of the CCR

Ecological theory as a foundation to control pathogenic invasion in aquaculture [PDF]
, 2014 Detrimental host-pathogen interactions are a normal phenomenon in aquaculture animal production, and have been counteracted by prophylactic use of antibiotics. Especially, the youngest life stages of cultivated aquatic animals are susceptible to pathogen

The Electronic Journal of Combinatorics, 1994 Given a graph $G = (V,E)$, an even kernel is a nonempty independent subset $V' \subseteq V$, such that every vertex of $G$ is adjacent to an even number (possibly 0) of vertices in $V'$. It is proved that the question of whether a graph has an even kernel is NP-complete. The motivation stems from combinatorial game theory.

Dynamical symmetries in even-even Te nuclides
Physical Review C, 1987 The structure of the even-even Te nuclides with 114A134 is shown to consist of features that can be associated with underlying low-energy collective excitations, as well as particle-hole intruder and two-quasiparticle configurations. Energy level positions and branching ratios from new and existing measurements can be reasonably well fitted with a ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
