$Λ$ and $Σ$ Excitations and the Quark Model [PDF]
, 2020 The spectrum of $\Lambda$ and $\Sigma$ excitations is reviewed taking into account (nearly) all hyperon resonances which were seen in early analyses or in one of the recent partial-wave analyses. The spectrum is compared with the old Isgur-Karl model and the Bonn model.

The Effect of Pore Structure in Flapping Wings on Flight Performance [PDF]
arXiv, 2021 This study investigates the effects of porosity on flying creatures such as dragonflies, moths, hummingbirds, etc. wing and shows that pores can affect wing performance. These studies were performed by 3D porous flapping wing flow analyses on Comsol Multiphysics.

A Prismatic Analyser concept for Neutron Spectrometers [PDF]
, 2014 A development in modern neutron spectroscopy is to avoid the need of large samples. We demonstrate how small samples together with the right choice of analyser and detector components makes distance collimation an important concept in crystal analyser spectrometers.

Extended Optical Model Analyses of Elastic Scattering, Direct Reaction, and Fusion Cross Sections for the 9Be + 208Pb System at Near-Coulomb-Barrier Energies [PDF]
Phys.Rev. C72 (2005) 064602, 2005 Based on the extended optical model approach in which the polarization potential is decomposed into direct reaction (DR) and fusion parts, simultaneous $\chi^{2}$ analyses are performed for elastic scattering, DR, and fusion cross section data for the $^{9}$Be+$^{208}$Pb system at near-Coulomb-barrier energies.

Sequencing, Characterization, and Comparative Analyses of the Plastome of Caragana rosea var. rosea
International Journal of Molecular Sciences, 2018 To exploit the drought-resistant Caragana species, we performed a comparative study of the plastomes from four species: Caragana rosea, C. microphylla, C. kozlowii, and C. Korshinskii. The complete plastome sequence of the C. rosea was obtained using the

Illuminating Endocrine Evolution: The Power and Potential of Large-Scale Comparative Analyses.
Integrative and Comparative Biology, 2018 Hormones are central mediators of genotype-phenotype and organism-environment interactions. Despite these important functions, the role of selection in shaping hormonal mediators of phenotype remains poorly understood.

Comparative genomics and mutagenesis analyses of choline metabolism in the marine Roseobacter clade [PDF]
, 2015 Choline is ubiquitous in marine eukaryotes and appears to be widely distributed in surface marine waters; however, its metabolism by marine bacteria is poorly understood.
