Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile

Description: This article's aim is to determine whether (a) the spatial use of domestic dogs increases with habitat destruction, and (b) domestic dogs and habitat destruction drive the spatial use of native carnivores in a heavily degraded agricultural landscape. Conclusions highlight that domestic dog occupancy was positively correlated with habitat loss and future conditions of increased fragmentation and habitat loss will likely increase the potential contact between domestic dogs and native carnivores.

Dense Locally Finite Subgroups of Automorphism Groups of Ultraextensive Spaces

Description: Article verifying a conjecture of Vershik by showing that Hall’s universal countable locally finite group can be embedded as a dense subgroup in the isometry group of the Urysohn space and in the automorphism group of the random graph. It shows the same for all automorphism groups of known infinite ultraextensive spaces.

Development of Novel Approaches to Earth-abundant Methane Catalysis

Description: Research on catalytic cycles for C–H activation and functionalization of light alkanes based on the CMD (concerted metalation deprotonation) mechanism will be modeled for Earth-abundant metal dicarboxylates and related complexes. The impact of inner and outer coordination sphere effects upon catalytic cycles for light alkane functionalization will be assessed using computational chemistry techniques. The aforementioned studies will be leveraged to identify promising, synthetically feasible lead catalysts for experimental collaborators.

The Heart of Librarianship: A Literature Review of Outreach in Academic Libraries

Description: Presentation that provides a summary of the literature on library outreach and indicates how the literature review has impacted outreach developments at the UNT Libraries. Outreach has a positive impact on student success, but a clear definition of what outreach is looms beyond the literature. Intermixed with marketing, advertising, broader engagement methods, and social media use, outreach has become a catch-all term for activities that bring awareness to library resources, services, programs, spaces, and employees. It was presented at the UNT Libraries' Public Services Conversation Hour, an internal, divisional peer learning and training program.

Deep Minimum and a Vortex for Positronium Formation in Low-Energy Positron-Helium Collisions

Description: This article finds a zero in the positronium formation scattering amplitude and a deep minimum in the logarithm of the corresponding differential cross section for positron–helium collisions for an energy just above the positronium formation threshold. Results show that there is a valley in the logarithm of the positronium formation differential cross section that includes the deep minimum and also a minimum in the forward direction.

Inhibition of Very Long Chain Fatty Acids Synthesis Mediates PI3P Homeostasis at Endosomal Compartments

Description: This article uses metazachlor, an inhibitor of VLCFA synthesis, to find that VLCFAs are involved in the TGN/MVB distribution of PI3P. This effect is independent from either synthesis of PI3P by PI3-kinase or degradation of PI(3,5)P2 into PI3P by the SUPPRESSOR OF ACTIN1 (SAC1) phosphatase. Results suggest that PI3P might be transferable from TGN to MVBs and that VLCFAs act in this process.

Development of Neutral Red as a pH/pCO2 Luminescent Sensor for Biological Systems

Description: This article demonstrates for the first time that Neutral Red (NR) can also serve as a CO2 sensor, because of NR’s unique optical properties, which change with dissolved carbon dioxide (dCO2) concentrations. In this article optical sensitivity of NR was quantified as a function of changes in absorption and emission spectra to dCO2 in a pH 7.3 buffer medium at eight dCO2 concentrations.
