A model is developed for electromagnetic form factor of the pion. One-loop corrections are included in the linear σ−model. The ρ−meson contribution is added in an extended VMD model. The form factor, calculated without fitting parameters, is in a good agreement with experiment for space-like and time-like photon momenta. Loop corrections to the two-pion hadronic contribution a (had,π) μ to the ...

After administration of methamphetamine (METH) (2x2 mg/kg, 6 h apart) to vervet monkeys, long term but reversible dopaminergic deficits were observed in both in vivo and post-mortem studies. Longitudinal studies using positron emission tomography (PET) with the dopamine transporter (DAT)-binding ligand, [11C]WIN 35,428 (WIN), were used to show decreases in striatal WIN binding of 80% at 1 week ...

An increasing population of dementia patients produces substantial societal impacts. We assessed the prevalence of mild cognitive impairment (MCI) and all-cause dementia, including very mild dementia (VMD), in Taiwan. In a nationwide population-based cross-sectional survey, participants were selected by computerized random sampling from all 19 Taiwan counties and were enrolled between December ...

In this talk, recent results are presented of calculations of electromagnetic form factors of hadrons in the framework of two quantum field theories (QFT), (a) Dual-Large Nc QCD (DualQCD∞) for the pion, proton, and ∆(1236), and (b) the Kroll-Lee-Zumino (KLZ) fully renormalizable Abelian QFT for the pion form factor. Both theories provide a QFT platform to improve on naive (tree-level) Vector Me...

Variational mode decomposition (VMD) is a recently introduced adaptive signal decomposition algorithm with a solid theoretical foundation and good noise robustness compared with empirical mode decomposition (EMD). There is a lot of background noise in the vibration signal of diesel engine. To solve the problem, a denoising algorithm based on VMD and Euclidean Distance is proposed. Firstly, a mu...

Research on the price prediction of natural gas is great significance to market participants all kinds. In order predict prices more reliably, this paper introduces a quadratic decomposition technology based combination variational modal (VMD) and ensemble empirical (EEMD), which decomposes residual term (Res) after VMD by EEMD; then, new hybrid model called VMD-EEMD-Res.-LSTM constructed in wi...

Accurate PM2.5 concentration forecasting is crucial for protecting public health and atmospheric environment. However, the intermittent and unstable nature of PM2.5 concentration series makes its forecasting become a very difficult task. In order to improve the forecast accuracy of PM2.5 concentration, this paper proposes a hybrid model based on wavelet transform (WT), variational mode decompos...

PURPOSE To analyze functional and clinical data of Best vitelliform macular dystrophy (VMD) patients with mutations in the BEST1 gene. METHODS Best VMD patients with BEST1 mutations were evaluated prospectively regarding age, age of onset, best-corrected visual acuity (BCVA), fundus autofluorescence, fluorescein angiography, optical coherence tomography, and electro-oculography. Mutations in ...

Vector-Meson-Dominance model contribution to π 0 → 4γ is calculated. The result confirms old estimates that this contribution is much smaller than the purely electromagnetic photon spliting graph contribution calculated earlier. In the framework of the Vector-Meson-Dominance (VMD) model, the decay π 0 → 4γ was considered in [1] and [2]. However, no complete evaluation of the decay width can be ...
