Spectroscopic signatures of a bandwidth-controlled Mott transition at the surface of 1T-TaSe$_2$

, 2003
High-resolution angle-resolved photoemission (ARPES) data show that a metal-insulator Mott transition occurs at the surface of the quasi-two dimensional compound TaSe$_2$.

Modulation Transfer Function Obtained from Image Structures [PDF]

, 1989
A new and relatively simple method for edge gradient analysis (EGA) has been developed to determine the modulation transfer function (MTF) of photogrammetrical systems. The MTF can be calculated as the ratio of the amplitude of those frequencies present in the original edge to the amplitude of the same frequency in the scanned edge image.

MODULATION TRANSFER FUNCTIONS OF THE IONIZATION CHAMBER [PDF]

American Journal of Roentgenology, 1969
The blur in the measurement system is analyzed by bringing into the dosimetric system the concept of Modulation Transfer Function (MTF) which has recently been introduced into the radiographic system with fruitful results in the analysis of images.In this paper, the dosimetry, in air and in depth, of 190 kvp.

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Modulation Transfer Function Extraction and Parametric Effects

Havacılık ve Uzay Teknolojileri Dergisi
We compute the optical transfer function and corresponding satellite image estimate in order to test validity of our modulation transfer function (MTF) extraction algorithms. The test targets allow MTF computation by using slanted edge and sine wave star

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Effect of Radiation and Gravity Modulation on Unsteady MHD Free Convection Flow Through Porous Medium in Slip-Flow Regime with Entropy

Walailak Journal of Science and Technology, 2013
The effect of radiation and periodic oscillation of the gravitational field on free-convection from a vertical plate is investigated. It is assumed that the gravity modulation is given by a harmonic function superimposed on a constant.
