Calculation of the $$B\rightarrow K_{0,2}^*(1430)f_0(980)/\sigma $$ B→K0,2∗(1430)f0(980)/σ decays in the perturbative QCD approach

European Physical Journal C: Particles and Fields, 2019
Motivated by the observations of the decays $$B^0 \rightarrow K_0^{*}(1430)^0 f_0(980)$$ B0→K0∗(1430)0f0(980) and $$ B^0 \rightarrow K_2^{*}(1430)^0 f_0(980)$$ B0→K2∗(1430)0f0(980) from BaBar collaboration, we study the $$B^{0(+)} \rightarrow K_{0,2}^{*}(

Determining Compositeness of Hadronic Resonances: the $\Lambda (1405)$ Radiative Decay and the $a_{0} (980)$-$f_{0} (980)$ Mixing

, 2014
Recently the concept of compositeness has been developed so as to distinguish whether interested hadrons are hadronic molecules or not. Here, in terms of compositeness, we investigate $\bar{K} N$ molecular structure of the $\Lambda (1405)$ resonance with

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Dissatisfaction with Democracy: Evidence from the Latinobarómetro 2005 Insatisfacción con la Democracia: Evidencia de Latinobarómetro 2005

Journal of Politics in Latin America, 2010
Data for 17 Latin American countries collected by Latinobarómetro 2005 reveal that dissatisfaction with democracy is a sign of progress. Political stability and increased governmental effectiveness enable the better-educated leftish young to express ...

Analysis the $f_0(980)$ and $a_0(980)$ mesons as four-quark states with the QCD sum rules

, 2005
In this article, we take the point of view that the scalar mesons $ f_0(980)$ and $a_0(980)$ are diquark-antidiquark states $(qq)_{\bar{3}}(\bar{q}\bar{q})_3$, and devote to determine their masses in the framework of the QCD sum rules approach with the ...

Phenomenological and Physically Based Modeling of Flow Stress and Strengthening Mechanism of Inconel 718

Advanced Engineering Materials, EarlyView.
Nickel‐based alloys are widely used in high‐temperature applications due to their excellent mechanical strength and oxidation resistance. However, properties such as high‐temperature strength and pronounced work‐hardening make them difficult to machine.

Delegation, Presidential Regimes, and Latin American Regulatory Agencies Delegación, regimenes presidenciales y agencias reguladoras en América Latina

Journal of Politics in Latin America, 2010
During the 1990s, a large number of regulatory agencies were created or reformed in different sectors in Latin American countries. Almost all included political delegation mechanisms, intended as formal rules to enhance credible commitments to time ...

Measurement of $B^0\to\pi^+\pi^-\pi^+\pi^-$ Decays and Search for $B^0\to\rho^0\rho^0$

, 2008
We report on a search for the decay $B^0\to\rho^0\rho^0$ and other charmless modes with a $\pi^+\pi^-\pi^+\pi^-$ final state, including $B^0\to\rho^0\pi^+\pi^-$, non-resonant $B^0\to 4\pi^{\pm}$, $B^0\to\rho^0f_0(980)$, $B^0\to f_0(980)f_0(980)$ and $B^0\

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Demonstration of Yb-Doped Fiber Amplifier Operating near 980 nm with the Slope Efficiency Close to the Theoretical Limit

Photonics, 2022
In this paper, the scalability of slope efficiency of a Yb-doped fiber amplifier operating near 980 nm is studied with the core-pumping scheme. By means of numerical prediction, it is found that the theoretical limit of slope efficiency should be about ...
