Streptococcus pneumoniae infections induce inflammatory responses that contribute toward both disease pathogenesis and immunity, but the host-pathogen interactions that mediate these effects are poorly defined. We used the surface lipoprotein-deficient ∆lgt pneumococcal mutant strain to test the hypothesis that lipoproteins are key determinants of TLR-mediated immune responses to S. pneumoniae....
BACKGROUND Streptococcus suis causes invasive infections in pigs and occasionally in humans. The host innate immune system plays a major role in counteracting S. suis infections. The main components of S. suis able to activate the innate immune system likely include cell wall constituents that may be released during growth or after cell wall integrity loss, however characterization of these com...
We study a two-dimensional spin model obtained by "Higgsing" the rank-2 U(1) lattice gauge theory (LGT) with scalar or vector charges on L_x * L_y square under periodic boundary condition (PBC). There are p degrees of freedom per orbital and three orbitals unit cell in model. The resulting is stabilizer code consisting mutually commuting projectors that are, turn, Higgsing Gauss's law operators...
in this paper, we introduce a new model of point free topology for point-set topology. we study the basic concepts in this structure and will find that it is naturally close to point-set topology.
Lattice gauge theory (LGT) has been accepted as the most powerful tool for investigating nonperturbative strong interactions. Chinese physicists at Institute of High Energy Physics (IHEP), Institute of Theoretical Physics (ITP) and Peking Univ. (PKU) in Beijing, Nankai Univ. in Tianjin, Chengdu Univ. of Science and Technology and Sichuan Univ. in Chengdu, Zhejiang Univ. (ZJU) in Hangzhou, and Z...
In this paper we derive quark model results for scattering amplitudes and equivalent low energy potentials for heavy meson pairs, in which each meson contains a heavy quark. This “BB” system is an attractive theoretical laboratory for the study of the nuclear force between color singlets; the hadronic system is relatively simple, and there are lattice gauge theory (LGT) results for VBB(r) which...
Faced with high return rates, many e-commerce retailers are considering novel technical solutions to expedite the processing of returned items in their warehouses. One such solution consists lane-guided transport (LGT) vehicles. These small, electric vehicles follow optical markers on floor, picking up boxes at a depot and dropping them off workstations, releasing logistics workers focus produc...
Phylogenomics is aimed at studying functional and evolutionary aspects of genome biology using phylogenetic analysis of whole genomes. Current approaches to genome phylogenies are commonly founded in terms of phylogenetic trees. However, several evolutionary processes are non tree-like in nature, including recombination and lateral gene transfer (LGT). Phylogenomic networks are a special type o...
Cyanobacteria forged two major evolutionary transitions with the invention of oxygenic photosynthesis and the bestowal of photosynthetic lifestyle upon eukaryotes through endosymbiosis. Information germane to understanding those transitions is imprinted in cyanobacterial genomes, but deciphering it is complicated by lateral gene transfer (LGT). Here, we report genome sequences for the morpholog...
