We used the model nematode Caenorhabditis elegans infected with the human pathogen Staphylococcus aureus to identify components of epithelial immunity. Transcriptional profiling and reverse genetic analysis revealed that mutation of the C. elegans beta-catenin homolog bar-1 or the downstream homeobox gene egl-5 results in a defective response and hypersensitivity to S. aureus infection. Epistas...

Abstract Inspired by the fully heavy tetraquark states reported LHCb, ATLAS and CMS Collaborations, we perform a systematical investigation of low-lying pentaquark systems composed charm bottom quarks (anti-quark) in chiral quark model. With help channel-coupling, obtain several candidates, which are $$cccc\bar{b}$$ c<...

Previously, the switching field of nanolithographically defined single-domain permalloy and nickel bars was found to increase monotonically as the bar aspect ratio increases or as the bar width decreases. In this work, we will show, for the first time, that when the bar width is fixed, the switching field of nanolithographically defined single-domain nickel and cobalt bars changes nonmonotonica...

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...

The microlensing probability (optical depth τ) toward the Galactic center carries information about the mass distribution of the Galactic bulge/bar, so can be used to constrain the very uncertain shape parameters of the Galactic bar. In this paper we study a family of bar models with tunable triaxiality, boxyness and radial profile to span the range of plausible density models of the Galactic b...

Basic relation between numerical range and Davis-Wielandt shell of an operator $A$ acting on a Hilbert space with orthonormal basis $xi={e_{i}|i in I}$ and its conjugate $bar{A}$ which is introduced in this paper are obtained. The results are used to study the relation between point spectrum, approximate spectrum and residual spectrum of $A$ and $bar{A}$. A necessary and sufficient condition fo...

Stimulated by the meson-baryon molecular interpretations of $P_c$ states ($P_c(4312)/P_c(4440)/P_c(4457)$), we systematically study interactions between an $S-$wave charm-strange baryon $\Xi_c^{(\prime,*)}$ and anti-charmed meson $\bar{D}^{(*)}$ in a coupled channel analysis. Effective potentials for $\Xi_c^{(\prime,*)}\bar{D}^{(*)}$ one-boson-exchange model can be related to those $\Sigma_c^{(...

an aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. in this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial tfc (thin film composite) polyamide nanofilter. the effects of ph (6.5-8.5), pressure (4-10 bar), concentration of to...

Using high resolution N-body simulations of stellar disks embedded in cosmologically motivated dark matter halos, we study the evolution of bars and the transfer of angular momentum between halos and bars. We find that dynamical friction results in some transfer of angular momentum to the halo, but the effect is much smaller than previously found in low resolution simulations and is incompatibl...
