This paper employs a simulation model to investigate the effectiveness of cooperation selection (“selecting similar others”) and social influence (“do as others do”), since both mechanisms promote cooperation in theoretical analyses and experimental studies. However, it is unclear how effective coop...
Bounds are calculated for the average performance of the power method for the calculation of eigenvectors of symmetric and Hermitian matrices, thus an upper bound is found for the average complexity of eigenvector calculation. The condition number of a matrix is studied and sharp bounds are ...
In vitro systems mimicking brain regions, brain organoids, are revolutionizing the neuroscience field. However, characterization of their electrical activity has remained a challenge as it requires readout at millisecond timescale in 3D at single-neuron resolution. While custom-built microscopes used wit...
An alternative formulation of the MMSE MIMO Decoder for spatial multiplexing MIMO systems called the square root MMSE MIMO Decoder based on QR decomposition has appeared in the literature. It avoids inverting the upper triangular matrix but at the cost of dealing with a larger matrix, the extended...
Management of severe malaria remains a critical global challenge. In this study, using a multiplexed quantitative proteomics pipeline we systematically investigated the plasma proteome alterations in non-severe and severe malaria patients. We identified
Kuhn (1962/2012), in a chapter on Worldview, illustrates how humans may cope with changing gestalts: “An experimental subject who puts on goggles fitted with inverting lenses initially sees the entire world upside down...the result is extreme disorientation, an acute personal crisis. But after...
[9] develop a combined local and global optimization approach for jointly inverting two-dimensional direct current resistivity (DCR) and seismic refraction (SR) data for the purpose of reliably estimating the corresponding physical model parameters. On the issue of landslide susceptibility, in their ...
Furthermore, the asymptotic CI (ACI) can be approximated numerically by inverting Fisher’s information matrix. Thus, the 95% ACI for α, γ, and θ is easily obtained, respectively, as and . 3.2. MPS Method With the use of equation (11), the product spacing function for WGED ...
Based on an efficient scheme to represent the Fisher information matrix for an n-m-1 stochastic multilayer perceptron, a new algorithm is proposed to calculate the natural gradient without inverting the Fisher information matrix explicitly. When the input dimension n is much larger than the number ...
