Letkbe the number of weakly connected components in the subgraph ofDinduced byR. Sorge et al. [30] asked whether the DRPP is fixed-parameter tractable (FPT) when parameterized byk, i.e., whether there is an algorithm of running timeO(f(k))wherefis a function ofkonly and theOnotation ...

We show that networks operating in a CAS regime optimally model EEG signals, manifesting the activity of a local part of the outer layer of the brain. Our results suggest that locally the brain has neurons that are only weakly connected. Moreover, since the CAS regime is weakly dependent on...
We show that a simulated neuron network with neurons weakly connected does produce CAS patterns, and additionally produces an output that optimally model experimental electroencephalograph (EEG) signals. This work provides strong evidence that the brain operates locally in a CAS regime, allowing it ...
Poorly or weakly developed soil orders such as Entisols, Aridisols, and Inceptisols cover 38% of the ice-free land surface. Highly weathered soil orders such as Ultisols and Oxisols cover nearly 16%. Soil orders typically formed in forested regions such as Alfisols or Spodosols, having ...
It is shown that this distribution weakly converges to the joint distribution of independent Poisson random variables η 1, η 2,..., η b with some parameters λ i = Eη i , i ∈ ℕ.doi:10.1134/s0001434615030177YakymivSteklov Mathematical Institute, Moscow, Russia;A. L....
5 CsupCXEs (CsupCXE11, 14, 17, 18 and 20) were expressed weakly in OV-PG (Fig. 6A). Fatty acid synthase (FAS), Acetyl-CoA carboxylase (ACC) and Acyl-CoA oxidase (ACO) FAS has been reported to catalyze the conversion of malonyl-CoA and NADPH to saturated fatty acids15. 1 ...
Weakly connected Roman domination in graphs 2019, Discrete Applied Mathematics Citation Excerpt : Those variants are often related to modifying the conditions in which the vertices are dominated, or to adding extra properties to the Roman domination property itself. For instance we remark here variants...
period-one oscillations, respectively. The nonlinear dynamics change from complex to simple with the further increase of Δfbecause the carrier density oscillates weakly as Δfis much larger than the relaxation oscillation frequency. The simulated output intensities were evaluated using the Grassberger–...
To the flow-exposed electrode, high-voltage alternating current (AC) (from several to tens of kV) with frequencies from one to tens of kHz is applied [17,18] and another electrode is grounded (Figure 2). High voltage of a high frequency weakly ionises the surrounding fluid, producing ...
