A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Plethodon welleri exhibits strong seasonal shifts in elevational activity with abundance and occupancy being linked to terrain characteristics. Despite historical habitat assumptions, P. welleri occurs in a broad range of forest types across a larger elevation gradient. Photo Credit to Maxwell Ramey.

ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

A Passive Low‐Frequency, High‐Sensitivity Diamagnetic Levitation Accelerometer
ABSTRACT Despite the great potential of diamagnetic levitation accelerometers in detecting low‐frequency and weak motion, there is still a demand to further enhance their sensitivity for geophysical and microgravity applications. In this study, a straightforward structural modulating approach is presented to enhance the sensitivity of diamagnetic ...
