Low-frequency vibrations are foundational for material properties including thermal conductivity and chemical reactivity. To resolve the intrinsic molecular conformational dynamics in condensed phase, we implement time-resolved third-harmonic generation (TRTHG) spectroscopy to unravel collective skeletal motions in calcite, water, and aqueous salt solution in situ. The lifetime of three Raman-active modes...
Background: Mangroves are ecologically important and highly threatened forest communities. Observational and genetic evidence has confirmed the long distance dispersal capacity of water-dispersed mangrove seeds, but less is known about the relative importance of pollen vs. seed gene flow in connecting populations. We analyzed 980 Avicennia germinans for 11 microsatellite...
Fluorescent proteins (FPs) are luminescent biomolecules that emit characteristic hues upon irradiation. A group of calmodulin (CaM)-green FP (GFP) chimeras have been previously engineered to enable the optical detection of calcium ions (Ca²⁺). We investigate one of these genetically encoded Ca²⁺ biosensors for optical imaging (GECOs), GEM-GECO1, which fluoresces green...
The effect of bactericidal UV-C treatments (254 nm) on E. coli O157:H7 suspended in apple juice increased synergistically with temperature up to a threshold value. The optimum UV-C treatment temperature was 55 °C yielding a 58.9% synergistic lethal effect. Under these treatment conditions, the UV-heat (UV-H[subscript 55 °C]) lethal variability...

Fusarium crown rot (FCR) is one of the most widespread root and
crown diseases of wheat in the Pacific Northwest (PNW) of the United
States. Our objectives were to characterize crown rot severity and
distribution throughout the PNW by conducting a survey of 210 fields
covering the diverse dryland wheat-producing...
