Deep Minimum and a Vortex for Positronium Formation in Low-Energy Positron-Helium Collisions (open access)

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

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.

A New Method for Automated Measurement of Sand Dune Migration Based on Multi-Temporal LiDAR-Derived Digital Elevation Models (open access)

A New Method for Automated Measurement of Sand Dune Migration Based on Multi-Temporal LiDAR-Derived Digital Elevation Models

This article proposes a toe line tracking (TLT) method for the automated measurement of dune migration rate and direction using multi-temporal digital elevation models (DEM) derived from light detection and ranging (LiDAR) data to overcome a major limitation of the existing method of pairs of source and target points (PSTP).

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits (open access)

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits

Article states that though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design. Utilizing a genetically-informed design, the authors found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits.

Development of Neutral Red as a pH/pCO2 Luminescent Sensor for Biological Systems (open access)

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

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.

Dense Locally Finite Subgroups of Automorphism Groups of Ultraextensive Spaces

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.

A smartphone-based online system for fall detection with alert notifications and contextual information of real-life falls (open access)

A smartphone-based online system for fall detection with alert notifications and contextual information of real-life falls

This article presents the results of a prospective study investigating a proof-of-concept, smartphone-based, online system for fall detection and notification. Apart from functioning as a practical fall monitoring instrument, this system may serve as a valuable research tool, enable future studies to scale their ability to capture fall-related data, and help researchers and clinicians to investigate real-falls.

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (RubisCO) Is Essential for Growth of the Methanotroph Methylococcus capsulatus Strain Bath (open access)

Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (RubisCO) Is Essential for Growth of the Methanotroph Methylococcus capsulatus Strain Bath

This article demonstrates that shows both CO2 and RubisCO are essential for M. capsulatus Bath growth. CO2 tracing experiments supported that RubisCO mediates CO2 fixation and that a noncanonical Calvin cycle is active in this organism. The study provides insights into the expanding knowledge of methanotroph metabolism and implicates dually CH4/CO2-utilizing bacteria as more important players in the biogeochemical carbon cycle than previously appreciated. In addition, M. capsulatus and other methanotrophs with CO2 assimilation capacity represent candidate organisms for the development of biotechnologies to mitigate the two most abundant greenhouse gases, CH4 and CO2.

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

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.

Crucial Development: Criticality Is Important to Cell-to-Cell Communication and Information Transfer in Living Systems (open access)

Crucial Development: Criticality Is Important to Cell-to-Cell Communication and Information Transfer in Living Systems

This article is the fourth paper of the Special Issue Memory and Criticality. It bridges the the theoretical debate on the role of memory and criticality discussed in the three earlier manuscripts, with a review of key concepts in biology and focus on cell-to-cell communication in organismal development. The authors suggest that in conjunction with morphogenetic gradients, there exist gradients of information transfer creating cybernetic loops of stability and disorder, setting the stage for adaptive capability. Criticality, therefore, appears to be an important factor in the transmission, transfer and coding of information for complex adaptive system development.

Inhibition of Very Long Chain Fatty Acids Synthesis Mediates PI3P Homeostasis at Endosomal Compartments (open access)

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

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.

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile (open access)

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

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.

Dietary Polyphenol and Methylsulfonylmethane Supplementation Improves Immune, DAMP Signaling, and Inflammatory Responses During Recovery From All-Out Running Efforts (open access)

Dietary Polyphenol and Methylsulfonylmethane Supplementation Improves Immune, DAMP Signaling, and Inflammatory Responses During Recovery From All-Out Running Efforts

This article presents a study with the purpose to determine the effect of dietary supplementation with optimized curcumin, pomegranate ellagitannins, and MSM (R + MSM) on immune-associated mRNA during early recovery (i.e., up to 8 h post-exercise) following all-out running efforts (5-km, 10-km, and 21.1-km). The results demonstrate that supplementation with a combination of optimized curcumin, pomegranate ellagitannins, and methylsulfonylmethane resulted in changes that may improve biological recovery from all-out running efforts.
