Multitask deep-learning-based design of chiral plasmonic metamaterials (open access)

Multitask deep-learning-based design of chiral plasmonic metamaterials

This article presents an end-to-end functional bidirectional deep-learning (DL) model for three-dimensional chiral metamaterial design and optimization. This ML model utilizes multitask joint learning features to recognize, generalize, and explore in detail the nontrivial relationship between the metamaterials’ geometry and their chiroptical response, eliminating the need for auxiliary networks or equivalent approaches to stabilize the physically relevant output. This model efficiently realizes both forward and inverse retrieval tasks with great precision, offering a promising tool for iterative computational design tasks in complex physical systems. Other potential applications include photodetectors, polarization-resolved imaging, and circular dichroism (CD) spectroscopy.

Effects of UV Stabilizers on Polypropylene Outdoors (open access)

Effects of UV Stabilizers on Polypropylene Outdoors

This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harder—which is important for some PP applications, such as toy manufacturing.

Visual Narratives: Anti-racist Pedagogy in Art and Design

Video recording featuring guest panelists, Bridget R. Cooks, Ph.D., Omari Souza, and Wesley Taylor, this fourth installment of the 2044 series frames Afrofuturism and futurist thinking as a means for exploring the practices of design and museum curation as well as implications for art/design pedagogy. The panelists explore and discuss how hegemony is perpetuated, sharing the ways in which they decolonize within their curricula and pedagogy, as well as practice anti-racism in their work to reimagine risk or resist classification. While design institutions perpetuate neoliberalist ideals and language and teach under the paradigm of design for consumption, art/design education has the capacity to make a great impact by embracing the power of art and design to imagine alternative futures. The speakers also discuss important issues of cultural ethics, including copyright and appropriation, protections, and speaking up for community.

Genetic Differentiation of the South Florida Red-Shouldered Hawk (Buteo lineatus extimus) from the Nominate Subspecies (Buteo lineatus lineatus)

Article discusses how the south Florida subspecies of the Red-shouldered Hawk (Buteo lineatus extimus) is distinctly paler and smaller than other subspecies, reproduces at a lower rate, and can occupy very different habitats such as open marshes and grasslands with only scattered trees. The authors evaluated population differentiation between the south Florida population of Red-shouldered Hawks and two populations of eastern Red-shouldered Hawks (B. l. lineatus) in suburban (Cincinnati) and rural (Hocking Hills) environments in southern Ohio.

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.
