In this paper, we study the scattering amplitudes of ${D}^{0}{D}^{0}{\ensuremath{\pi}}^{+}\text{\ensuremath{-}}{D}^{*+}{D}^{0}$ coupled channels based on $K$ matrix within Chew-Mandelstam formalism. The ${D}^{0}{D}^{0}{\ensuremath{\pi}}^{+}$ invariant mass spectrum LHCb is fitted, and pole parameters ${T}_{cc}^{+}$ are extracted. analysis behavior suggests that may originate from a ${D}^{*+}{D}...
r is called commuting regular ring (resp. semigroup) if for each x,y $in$ r thereexists a $in$ r such that xy = yxayx. in this paper, we introduce the concept of commuting$pi$-regular rings (resp. semigroups) and study various properties of them.
The Cabibbo-Kobayashi-Maskawa (CKM) matrix element $\vert V_{ub}\vert$ is obtained from exclusive semileptonic $B \to \pi \ell \nu_\ell$ and $B_s K decays adopting the unitarity-based dispersion approach for determination of hadronic form factors (FFs) in whole kinematical range. We use lattice computations relevant susceptibilities FFs large-$q^2$ regime order to derive their behavior low-$q^2...
In this paper a complete robust control synthesis is performed for a hybrid power generation structure composed by a Fuel Cell and a Supercapacitor. The control strategies are applied to the DC-DC boost power converters associated to each power source. Multivariable PI control withH∞ performance,H∞ full and reduced order controllers are designed and compared. The multivariable PI controller is ...
Accumulating evidence indicates that cancer cells show specific alterations in phospholipid metabolism that contribute to tumour progression in several types of cancer, including colorectal cancer. Questions still remain as to what lipids characterize the outer edge of cancer tissues and whether those cancer outer edge-specific lipid compositions emerge autonomously in cancer cells. Cancer tiss...
In pancreatic β-cells, glucose-induced mitochondrial ATP production plays an important role in insulin secretion. The mitochondrial phosphate carrier PiC is a member of the SLC25 (solute carrier family 25) family and transports Pi from the cytosol into the mitochondrial matrix. Since intramitochondrial Pi is an essential substrate for mitochondrial ATP production by complex V (ATP synthase) and...
We estimate the density matrix element for the pi(0), eta, and eta(') production from the vacuum in the large-N(c) limit. As a consequence, we find that the QCD axial anomaly leads to highly nontrivial corrections to the usual flavor SU(3) relations between B(0)-->K(0)pi(0), B(0)-->K(0) eta, and B(0)-->K(0)eta(') decay amplitudes. These corrections may explain why the B-->Keta(') branching rati...
We analyse the theory of single photoionization (PI) and high-order harmonic generation (HHG) by intense lasers from aligned molecules. We show that molecular-frame photoelectron angular distributions can be extracted from these measurements. We also show that, under favourable conditions, the phase of PI transition dipole matrix elements can be extracted from the HHG spectra. Furthermore, by v...
Driven by directional interparticle interactions, e.g., hydrophobic patchy, pi-pi, dipolar, and hydrogen bonding interactions, certain small molecules self-assemble in aqueous solution to form nanofibers (or other nanostructures) and consequently result in hydrogels. Because of their inherent advantages such as biocompatibility, biodegradability, and morphological resemblance of extracellular m...
