A QCD analysis of ¯ pN → γ * π and ¯ pN → γ * γ Where is the pion in the proton ? We study the scaling regime of nucleon-anti-nucleon annihilation into a deeply virtual photon and a photon or meson, ¯ pN → γ * π, ¯ pN → γ * γ, in the forward direction. The leading twist amplitude factorizes into an antiproton distribution amplitude, a short-distance matrix element and a long-distance dominated ...
In vivo in the prostate gland, basal epithelial cells adhere to laminin 5 (LM5) via alpha3beta1 and alpha6beta4 integrins. When placed in culture primary prostate basal epithelial cells secrete and adhere to their own LM5-rich matrix. Adhesion to LM5 is required for cell survival that is dependent on integrin-mediated, ligand-independent activation of the epidermal growth factor receptor (EGFR)...
This paper mathematically analyzes the integral generalized policy iteration (I-GPI) algorithms applied to a class of continuous-time linear quadratic regulation (LQR) problems with the unknown system matrix A. GPI is the general idea of interacting policy evaluation and policy improvement steps of policy iteration (PI), for computing the optimal policy. We first introduce the update horizon },...
It is hypothesized that active treatment of peri-implantitis (PI) leads to re-stabilization of dental implants. The aim was to assess whether or not dental implants can re-stabilize following treatment of PI. To address the focused question, MEDLINE/PubMed and Google-Scholar databases were explored from 1977 up to and including August 2013. Any disagreements between the authors were resolved vi...
Independent Component Analysis (ICA) is a classical method for Blind Source Separation (BSS). In this paper, we are interested in ICA in the presence of noise, i.e., the noisy ICA problem. Pseudo-Euclidean Gradient Iteration (PEGI) is a recent cumulant-based method that defines a pseudo Euclidean inner product to replace a quasi-whitening step in Gaussian noise invariant ICA. However, PEGI has ...

In this work, we study the spin density matrix element $\rho_{00}$ of $\phi$ in decay $J/\psi \rightarrow \eta \pi \phi$. previous studies, a band around 1.4 GeV on $\pi^0\phi$ distribution Dalitz plot was reported by BESIII Collaboration. This structure may be caused production resonance or triangle singularity mechanism. We find that predictions elements final based these mechanisms show dist...
مدلسازی پیلهایسوختی شده است. اما بسیاری از این روشها به طور عملی و آزمایشگاهی بررسی نشده است و هنوز کمبود مطالعات موشکافانه روی پارامترها و روابط مربوط به متغیرهای عملکرد مشاهده می شود. از سوی دیگر، تنها مدلها و روشهای کمی به طور مخصوص به طراحی کنترلکننده پرداختهاست. مدلی که در این جا استفاده شدهاست، یک مدل به منظور تسهیل شبیهسازی سیستم قدرت همراه با پیلسوختی است و تنها نیاز به چند متغیر ا...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
Polymer modified fillers in composites has attracted the attention of numerous researchers. These fillers are composed of core-shell structures that exhibit enhanced physical and chemical properties that are associated with shell surface control and encapsulated core materials. In this study, we have described an apt method to prepare polyimide (PI)-modified aluminum nitride (AlN) fillers, AlN@...
