Determination of metallization degree of pre-reduced chromite with image and rietveld analysis [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2020
Metallization degree of pre-reduced chromite was determined using two methods. The chromite samples were reduced in the solid state by methane-hydrogen gas mixtures.

Acquisition of a single grid-based phase-contrast X-ray image using instantaneous frequency and noise filtering

open access: yesBioMedical Engineering OnLine, 2022
Background To obtain phase-contrast X-ray images, single-grid imaging systems are effective, but Moire artifacts remain a significant issue. The solution for removing Moire artifacts from an image is grid rotation, which can distinguish between these ...

Phase-sensitive nuclear target spectroscopy

open access: yesPhysical Review Research, 2020
Mössbauer nuclei feature exceptionally narrow resonances at hard x-ray energies, which render them ideal probes for structure and dynamics in condensed-matter systems, and a promising platform for x-ray quantum optics and fundamental tests.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).
