A s evidenced in Paleolithic cave paintings of fi sh dating from 17,000 years ago, human-fi sh interactions have existed for thousands of years (Valladas et al. 2001). The earliest interactions likely involved fi sh as food and were necessarily tied to geographic access (i.e., island or coastal locations). Over time, the establishment of farm fi shing and the emergence of modern capture and tra...
We present an evaluation of the ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ and ${K}^{\ifmmode\pm\else\textpm\fi{}}$ box contributions to hadronic light-by-light piece muon's anomalous magnetic moment, ${a}_{\ensuremath{\mu}}$. The calculation corresponding electromagnetic form factors (EFFs) is performed within a Dyson-Schwinger equations (DSE) approach quantum chromodynamics. These ar...
Background: The relationship between fi broblasts, myofi broblasts, and smooth muscle cells within the airway wall remains poorly understood. Objective: The cellular characteristics of primary bronchial fi broblasts from patients with asthma were investigated by evaluating the expression of 3 proteins: α–smooth muscle actin (SMA), fi bronectin containing extra type III domain A (EDAcFN), and sm...

The importance of teacher talk in Arabic-speaking learning is not only as a medium to organize the class and train students. However, also source language acquisition means for achieving objectives. This research aims to: 1) explore type modes Arabic Speaking learning, 2) most dominant that occurs learning. researcher used qualitative approach, this case study. methods data collection are obser...
We study two- and three-gluon glueballs of $C=+$ using the method QCD sum rules. systematically construct their interpolating currents, find that all spin-1 currents vanish. This suggests ``ground-state'' do not exist within relativistic framework. calculate masses two-gluon with ${J}^{PC}={0}^{\ifmmode\pm\else\textpm\fi{}+}/{2}^{\ifmmode\pm\else\textpm\fi{}+}$ ${J}^{PC}={0}^{\ifmmode\pm\else\t...
For a particle moving on half-line or in an interval the operator $\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{p}=\ensuremath{-}i{\ensuremath{\partial}}_{x}$ is not self-adjoint and thus does qualify as physical momentum. Consequently canonical quantization based \^{}\fi{}}{p}$ fails. Based upon alternative concept for momentum ${\stackrel{\ifmmode \^{}\fi{}}{p}}_{R}$, we show that can indeed be ...
Th e fi nancial regulation architecture in both the United States and China developed during eras when retail deposits and bank loans were the primary mode of fi nancial intermediation. Th e function of banks is to transform short-term deposits into long-term loans, while providing liquidity for depositors. Experience has taught regulators hard lessons that this activity must be subject to prud...
