Effect of thermodynamic coupled simulation condition on microstructure and stress rupture properties of DZ406 alloy

Journal of Aeronautical Materials, 2022
There is a problem about microstructure evolution and properties degradation for the superalloy turbine blades in long term service conditions. DZ406 alloy samples were pre-loaded to simulate the high temperature service environment of turbine blades ...

Radiative decays with light scalar mesons and singlet-octet mixing in ChPT

, 2007
We study different types of radiative decays involving f0(980) and a0(980) mesons within a unified ChPT-based approach at one-loop level. Light scalar resonances which are seen in pi pi, pi eta, K K-bar channels of phi(1020) radiative decays and in J/psi

Isospin breaking and f0(980)-a0(980) mixing in the η(1405) → π0f0(980) reaction

EPJ Web of Conferences, 2014
We make a theoretical study of the η(1405) → π0f0(980) and η(1405) → π0a0(980) reactions to determine the isospin violation and the mixing of the f0(980) and a0(980) resonances. We make use of the chiral unitary approach where these two resonances appear

Decays of sigma, kappa, a0(980) and fo(980) [PDF]

The European Physical Journal C, 2006
Ratios of coupling constants for these decays are compared with q-qbar predictions and Jaffe's 4-quark model. In both models, the predicted ratio g^2(kappa -> K-pi)/ g^2(sigma -> pi-pi) is much too small. Also, for q-qbar, the predicted ratio g^2(kappa -> K-eta ')/g^2(kappa -> K-pi) is much larger than observed. Both models fail for g^2(fo -

Excited scalar mesons in a chiral quark model [PDF]

, 1999
First radial excitations of the isoscalar and isovector scalar mesons f_0(400-1200), f_0(980) and a_0(980) are investigated in the framework of a nonlocal version of a chiral quark model of the Nambu--Jona-Lasinio type.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Study the $$B^{0}_{(s)}$$ B ( s ) 0 decays into $$\phi $$ ϕ and a scalar or vector meson

European Physical Journal C: Particles and Fields, 2021
In the present work, we investigate the decays of $$B^{0}_{(s)} \rightarrow \phi \pi ^{+}\pi ^{-}$$ B ( s ) 0 → ϕ π + π - with the final state interaction based on the chiral unitary approach. In the final state interaction of the $$\pi ^+\pi ^-$$ π + π -

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

f0(980) meson as a K bar K molecule in a phenomenological Lagrangian approach

, 2008
We discuss a possible interpretation of the f0(980) meson as a hadronic molecule - a bound state of K and bar K mesons. Using a phenomenological Lagrangian approach we calculate the strong f0(980) to pi pi and electromagnetic f0(980) to gamma gamma ...
