On solving the vertical generalized linear complementarity problem associated with a vertical block P-matrix
… problem (VGLCP) when the associated matrix is a vertical block P-matrix (VBP). The objective of this study is to implement the algorithm on a large scale using the Python programming language. We also use a Python code to generate test VBP- matrices Ebiefung et al. (2022), and used …

Scattering and mesons
We present the P-matrix, an alternative method to parameterize the S-matrix, which is particularly useful for low energy meson-meson scattering. We discuss its basic properties and use it to analyze the isospin 0 and 2 s-wave [pi] [pi] scattering. We construct the S-matrix from our analysis and …

Digital model reference aircraft control
… decoupled DC-9 model. The change of control matrix elements is controlled by (1) an error vector equal to the difference between state variables of the model and those of the STOL, (2) the present values of the pilot inputs and STOL state variables, (3) a P matrix obtained from the equation …

Applications of Gaussian Process Regression to the Pricing and Hedging of Exotic Derivatives
… composed of the input vector X which is a n × p matrix and Y an n×1 vector of targets, where n is the number of training input vectors and p is the number of inputs. Using a GPR with a squared-exponential kernel tuned by maximising the log-likelihood, we established that this GPR works reasonably …

MECHANISM OF TRANSCRIPTIONAL REPRESSION OF MMP-9 BY INTERFERON-β
<p>Matrix metalloproteinase-9 (MMP-9) is a 92 kDa zinc-dependant endopeptidase that degrades components of the extracellular matrix. Enhanced expression of MMP-9 has been implicated in many pathological conditions including cancer metastasis, multiple sclerosis, and atherosclerosis. Although it has …

TDDFT calculations for excitation spectra of solids and superstructures utilizing mGGA
… because that we approximate the transition matrix elements by the LDA p-matrix elements via (mGGA) which contains the singularity of the type fXC,00(q) ∼ 1/q2 as q → 0. Thus, Our studies provide some insight into the theoretical calculation of optical spectra of semiconductor alloys.

Expression, activation, and regulation of matrix metalloproteinase 2 (MMP-2) in the bovine corpus luteum
<p>Matrix metalloproteinases (MMPs) have been postulated to be important for angiogenesis and for tissue remodeling events associated with corpus luteum (CL) development. The MMPs are mainly regulated at three levels, transcription, activation, and inhibition by endogenous tissue inhibitors of …
