Orbital Optimization in the Density Matrix Renormalization Group, with applications to polyenes and \beta-carotene [PDF]

open access: yes, 2007
In previous work we have shown that the Density Matrix Renormalization Group (DMRG) enables near-exact calculations in active spaces much larger than are possible with traditional Complete Active Space algorithms.

Fuzzy-Logic-Controlled Hybrid Active Filter for Matrix Converter Input Current Harmonics

open access: yesEnergies, 2022
The proliferation of matrix converter interfaces coupled with traditional loads produces nonstandard and high-frequency harmonics in the range of (2 to 150) kHz in the power system.

Extracellular Matrix Rigidity Promotes Invadopodia Activity [PDF]

open access: yesCurrent Biology, 2008
Invadopodia are actin-rich subcellular protrusions with associated proteases used by cancer cells to degrade extracellular matrix (ECM) [1]. Molecular components of invadopodia include branched actin-assembly proteins, membrane trafficking proteins, signaling proteins, and transmembrane proteinases [1]. Similar structures exist in nontransformed cells,

Similarities and differences in the construction of dispersion laws for charge carriers in semiconductor crystals and adiabatic potentials in molecules [PDF]

open access: yes, 2014
Using the group theory and the method of invariants, it is shown how the vibronic potential can be written in a matrix form and the corresponding adiabatic potentials can be found. The molecule having $D_{3d}$ symmetry is considered herein as an example.

Sterile Plus Active Neutrinos and Neutrino Oscillations [PDF]

open access: yes, 2013
Using a 3 + 1 neutrino model with one sterile and the three standard active neutrinos with a 4x4 unitary transformation matrix, U, relating flavor to mass neutrino states, the probability of $\nu_\mu$ to $\nu_e$ transition is estimated using sterile ...

Integrated Active-Matrix Capacitive Sensor Using a-IGZO TFTs for AMOLED

open access: yesIEEE Journal of the Electron Devices Society, 2018
We report a capacitive touch sensor using a-IGZO TFTs as active components to improve touch sensitivity and output robustness. The output potential difference between touched/untouched states is 1.7 V without readout buffer.

Control of matrix metalloproteinase catalytic activity [PDF]

open access: yesMatrix Biology, 2007
As their name implies, MMPs were first described as proteases that degrade extracellular matrix proteins, such as collagens, elastin, proteoglycans, and laminins. However, studies of MMP function in vivo have revealed that these proteinases act on a variety of extracellular protein substrates, often to activate latent forms of effector proteins, such ...

Pyrone-based inhibitors of metalloproteinase types 2 and 3 may work as conformation-selective inhibitors. [PDF]

open access: yes, 2011
Matrix metalloproteinases are zinc-containing enzymes capable of degrading all components of the extracellular matrix. Owing to their role in human disease, matrix metalloproteinase have been the subject of extensive study.
