STRUCTURE OF INTERSECTION GRAPHS

Structure of intersection graphs

Let G be a finite group and let N be a fixed normal subgroup of G.In this paper, a new kind of graph on G, namely the intersection graph is defined and studied.We use to denote this graph, with its vertices are SAMe all normal subgroups of G and two distinct vertices are adjacent if their intersection in N.We show some properties of this graph.For

Overexpression of lpxT Gene in Escherichia coli Inhibits Cell Division and Causes Envelope Defects without Changing the Overall Phosphorylation Level of Lipid A

LpxT is an inner membrane protein that transfers a phosphate group from the essential lipid undecaprenyl pyrophosphate (C-55PP) to the lipid A moiety of lipopolysaccharide, generating a lipid A tris-phosphorylated species.The protein is encoded by the non-essential lpxT gene, which is conserved in distantly related Gram-negative bacteria.In this wo

Shape optimization of closed-box girder considering dynamic and aerodynamic effects on flutter: a CFD-enabled and Kriging surrogate-based strategy

Shape optimization of single box girder allows the bridge to achieve the most favourable aerodynamic performance.Currently, aerodynamic optimization of bridge deck is usually achieved by traversing all potential schemes using wind tunnel tests or computational fluid dynamics (CFD), which are time-consuming, laborious, and restricted to few numbers

Dopaminergic Neuromodulation of Spike Timing Dependent Plasticity in Mature Adult Rodent and Human Cortical Neurons

Synapses in the cerebral cortex constantly change and this dynamic property regulated by the action of neuromodulators such as dopamine (DA), is essential for reward learning and memory.DA modulates spike-timing-dependent plasticity (STDP), a cellular model of learning and memory, in juvenile rodent cortical neurons.However, it is unknown whether t
