On Tensor Squares of Reducible Representations of Almost Simple Groups. II

Моделирование и анализ информационных систем, 2011
Almost simple {SM}_m -groups are considered. A group G is called {SM}_m -group if the tensor square of any irreducible representation is decomposed into the sum of all characters with multiplicities not greater than m.

Liberation Through Narration: A Novel Humanistic Framework to Address Body Dissatisfaction

The Journal of Humanistic Counseling, EarlyView.
ABSTRACT Though body dissatisfaction is nuanced and pervasive, the magnitude of body dissatisfaction is undercut by essentialist conceptualizations of the body and medicalized metrics of wellness tied to disordered eating. Hence, there is a need for a contextualized and sustaining framework to address and promote healing from body dissatisfaction ...

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, EarlyView.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

Laser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Q-Conjugacy character table for the non-rigid group of 2,3-dimethylbutane [PDF]

Journal of the Serbian Chemical Society, 2009
Maturated and unmaturated groups were introduced by the Japanese chemist Shinsaku Fujita, who used them in the markaracter table and the Q-conjugacy character table of a finite group.

Irreducible Characters of the Generalized Symmetric Group

Journal of Lie Theory
The paper studies how to compute irreducible characters of the generalized symmetric group $C_k\wr{S}_n$ by iterative algorithms. After reproving the Ariki-Koike version of the Murnaghan-Nakayama rule by vertex algebraic methods, we formulate a new iterative formula for characters of the generalized symmetric group. As applications, we find a numerical

On the number of irreducible characters in a finite group II

Hokkaido Mathematical Journal, 1983
[Part I, cf. ibid. 12, 74-82 (1983; Zbl 0517.20002).] Let B be a p-block of the finite group G, P a Sylow p-subgroup of G, D a defect group of B, k(B) the number of irreducible complex characters in B and m(B) the number of indecomposable direct summands of the block ideal B considered as a P-module under the conjugation action. The main result of this

Beyond Directions: Symmetry‐Aware Rotation Sets for Triaxial Diffusion Encoding by Geometric Filter Optimization

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve the accuracy of diffusion‐weighted powder average signals for diffusion encoding with arbitrary b‐tensors. Methods We identify an intrinsic dihedral (D2$$ {D}_2 $$) symmetry of diffusion signals for arbitrary diffusion encoding, which defines their natural signal space (a quotient of 3D rotations).

Time‐Efficient Interleaved Spin Density‐Weighted and Inversion Recovery 23Na MRI of the Human Calf Muscle at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Spin density‐weighted (SDW) and inversion recovery (IR) 23Na MRI provide different sodium contrasts with complementary information. Therefore, the aim was to develop a time‐efficient sequence scheme capable of providing both contrasts by acquiring SDW and IR 23Na MRI data within a single sequence without additional measurement time ...
