Weak-Light Image Enhancement Method Based on Adaptive Local Gamma Transform and Color Compensation (open access)

Weak-Light Image Enhancement Method Based on Adaptive Local Gamma Transform and Color Compensation

This article proposes a correction method for image enhancement models based on an adaptive local gamma transformation and color compensation inspired by the illumination reflection model. It is demonstrated that the proposed method adaptively reduces the influence of uneven illumination to avoid overenhancement and improves the visual effect of low-light images.

Formulating a Scalable Approach to Patron-Requested Digitization in Archives (open access)

Formulating a Scalable Approach to Patron-Requested Digitization in Archives

This article examines how archives were forced to rethink their modes of providing access to physical collections because of the coronavirus of 2019 (COVID-19). Whereas difficult copyright questions raised by reproducing items could previously be skirted by requiring researchers to work with materials in person, the long-term closure of reading rooms and decrease in long-distance travel mean that archives need a workflow for handling user digitization requests that is scalable and requires consulting only easily identifiable information and, assuming full reproduction is off the table, reproducing items in a collection under 17 U.S.C. § 108 or through a strategy of rapid risk assessment. There is a challenge in creating a policy that will work across different formats and genres of archival materials, so this article offers some suggestions for how to think about these parameters according to US copyright law and calls for a committee of experts to work out a model policy that could serve remote users of archival collections even after the COVID-19 crisis has passed.

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 Library History Seminar XIV: Libraries Without Borders event which was held virtually on June 10-12, 2021.

Approaching Bounded Rationality: From Quantum Probability to Criticality (open access)

Approaching Bounded Rationality: From Quantum Probability to Criticality

This article discusses the decision-making model (DMM), a paradigmatic instance of criticality, which deals with bounded rationality issues in a similar way as quantum probability (QP), generating choices that cannot be accounted by classical probability (CP). This work may contribute to considering criticality as another possible fundamental pillar in order to improve the understanding of cognition and of quantum mechanics.

Effect of amorphous cellulose on the deformation behavior of cellulose composites: molecular dynamics simulation

This article is a study aimed at predicting and enhancing the properties of the blend, as well as exploring the mechanism, of a polylactic acid (PLA)/amorphous cellulose composite system through molecular characterization. The static properties of the amorphous cellulose/PLA blend model and the mechanical response of the material under uniaxial tension were studied by molecular dynamics simulation to establish the structure–property relationship.

Early Oxidative Transformations During the Biosynthesis of Terrein and Related Natural Products (open access)

Early Oxidative Transformations During the Biosynthesis of Terrein and Related Natural Products

This article combines heterologous expression and in vitro studies to show that the flavin-dependent monooxygenase (FMO) TerC catalyzes the initial oxidative decarboxylation of 6-HM. The results demonstrate that the biosynthetic pathways of terrein and related(polychlorinated) congeners diverge after oxidative decarboxylation of the lactone precursor that is catalyzed by a conserved FMO and further indicate that early dehydration of the side chain is an essential step.

An Investigation of the Organizational Impact of Computer Technology in Secondary Science Classrooms

This article investigates the organizational impact of computer technology on four secondary science teachers’ teaching actions using the construct of community of practice. Analysis of data reveals three social participation structures that collectively orchestrated students’ science content learning: (1) students’ membership, (2) access to the structured tasks, and (3) confirmation of students’ learning of science concepts.

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile (open access)

Evidence of Endozoochory in Upland Geese Chloephaga picta and White-Bellied Seedsnipes Attagis malouinus in Sub-Antarctic Chile

This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.
