Cladistic analysis of the section Adonanthe under genus Adonis L. (Ranunculaceae) from East Asia

open access: yesJournal of Asia-Pacific Biodiversity, 2017
Cladistic analysis was conducted for 11 taxa belonging to sect. Adonanthe in the gen. Adonis in East Asia on the basis of morphological and cytological characters, and the evolutionary change of major diagnostic characters and the validity of the ...

First Report of the Immature Stages of the Leaf-Mining Genus Subclemensia Kozlov, 1987 (Lepidoptera: Incurvariidae), with a Re-Illustration of the Type Species and a Generic Concept Discussion Based on Immature Characters

open access: yesInsects, 2022
The immature stages of primitive Lepidoptera can provide quite different but often useful morphological evidence and synapomorphies from those of adults. Incurvariidae is one of the most primitive lineages of extant Lepidoptera, which is species-poor but

On the primitive characters of the Poincaré group [PDF]

open access: yesCommunications in Mathematical Physics, 1968
We calculate explicitely the traces of the different types of irreducible representations of the Poincare group. These have the form of generalized class functions and their mathematical structure follows from a generalization to non-compact groups of Frobenius' construction of induced characters.

Tra essere e agire. I mille volti della paura nella trilogia di Batman di Christopher Nolan [PDF]

open access: yesOcula, 2014
The aim of this study is a semiotic analysis of the Nolan's Batman series (Batman Begins/2005, The Dark Knight/2008, The Dark Knight Rises/2012). It goes over dimension of figural, space and passion in order to highlight fear as a complex, primitive and ...

Spectral Graph-based Features for Recognition of Handwritten Characters: A Case Study on Handwritten Devanagari Numerals

open access: yesJournal of Intelligent Systems, 2018
Interpretation of different writing styles, unconstrained cursiveness and relationship between different primitive parts is an essential and challenging task for recognition of handwritten characters.

Prime characters and primitivity

open access: yesJournal of Algebra, 1990
A (complex) character of a finite group is called quasiprimitive if it is irreducible and if its restriction to every normal subgroup is a multiple of an irreducible character. It is known that every quasiprimitive character of a finite solvable group is primitive, i.e. not induced by a character of a proper subgroup.

On the Mean Values of Certain Character Sums

open access: yesAbstract and Applied Analysis, 2013
Let q≥5 be an odd number. In this paper, we study the fourth power mean of certain character sums ∑χmodq,χ-1=-1*∑1≤a≤q/4aχa4 and ∑χmodq,χ-1=1*∑1≤a≤q/4aχa4, where ∑‍* denotes the summation over primitive characters modulo q, and give some asymptotic ...

Astragalar Morphology of Selected Giraffidae. [PDF]

open access: yesPLoS ONE, 2016
The artiodactyl astragalus has been modified to exhibit two trochleae, creating a double pullied structure allowing for significant dorso-plantar motion, and limited mediolateral motion.
