Breaking the Blend: A multi-tracer kinematic decomposition method for IFS data applied to disentangling the AGN outflow and circumnuclear ring in NGC 5728 with JWST

Abstract Integral field spectroscopy (IFS) of the central kiloparsecs of active galactic nuclei (AGN) reveals a mixture of spatially coincident emission from star-formation and AGN feedback exciting the interstellar medium. Disentangling these components remains a challenge, as m...

Lake size is associated with the relationship between body mass and gut microbiota alpha diversity in threespine stickleback (Gasterosteus aculeatus)

Lake size is associated with ecological conditions that can affect the microbiome of hosts, such as diet and habitat characteristics. However, whether host-microbe interactions are affected by lake size remains poorly understood. We characterized the gut microbiota of 191 wild th...

Cold-water gut isolate from threespine stickleback ( Gasterosteus aculeatus ) reveals polypropylene surface oxidation and co-culture inhibition

ABSTRACT Polyethylene terephthalate (PET) and polypropylene (PP), two of the most widely produced plastics in the United States, persist in diverse environments worldwide and may persist longer in cold-water environments where plastic-degrading microbial taxa have been poorly cha...

Fiber optic-based magnetostrictive sensor for monitoring pipe wall thickness

This article presents a novel sensor concept for continuous long-term monitoring of pipe or tank wall thickness that is based on strain measurements in a magnetostrictive material. The proposed sensor detects wall thinning in pipes or tanks by monitoring magnetic flux leakage (MF...

Anatomy and impact of a high Arctic atmospheric river driving extreme winter rain and snowfall

Abstract. Atmospheric rivers (ARs) transport concentrated fluxes of heat and moisture poleward, driving temperature and precipitation extremes. Yet, their vertical structure in the High Arctic – where small thermodynamic perturbations govern rain-snow partitioning and cryospheric...

Efficacy of mitigation translocation from Anchorage, Alaska airfields for short-eared owls and red-tailed hawks

Abstract Background Mitigation translocation is widely used at airfields to reduce wildlife-aircraft strike risk, yet few studies have evaluated its effectiveness for raptors, and none have been conducted in Alaska. We assessed post-release return rates for red-tailed hawks ( But...
