Using art history to explore society's changing connections with agriculture

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Food insecurity is a looming challenge that especially affects those least fortunate. Consumer food choices have a substantial impact on the sustainability of current food systems. Here, we use art as a lens through which to consider our contemporary and historical relationship to one of the world's most crucial crops, the potato, in the context of the

Joint Radar Jamming and Communication System Design Based on Universal Filtered Multicarrier Chirp Waveform

open access: yesRemote Sensing
In this article, we propose a joint waveform based on universal filtered multicarrier (UFMC) chirp for radar jamming and communication joint systems. Modulation of radar jamming chirp signals and communication signals on different subcarrier groups in ...

A Countermeasure Against Random Pulse Jamming in Time Domain Based on Reinforcement Learning

open access: yesIEEE Access, 2020
Pulse jamming is one of the common malicious jamming patterns that can significantly reduce the of wireless communication's reliability. This paper investigates the problem of anti-jamming communication in a random pulse jamming environment.

Anti-jamming Technology in Small Satellite Communication

open access: yesJournal of Physics: Conference Series, 2018
Small satellite communication has an increasingly important position among the wireless communications due to the advantages of low cost and high technology. However, in view of the case that its relay station stays outside the earth, its uplink may face interference from malicious signal frequently.

Large language models unlock large text corpora in the search for data on medicinal plants and fungi

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Millions of people worldwide depend on plants and fungi for their healthcare needs, yet our understanding of which species are used medicinally—and how—remains fragmented and incomplete. As part of Kew's Plants for Health service, we developed a pipeline to mine large text corpora for information on natural products, initially focusing on the medicinal

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

The “We” and “Me” of Identity in Hazardous Industry Organizations: Face Work Tactics Among Practicing Engineers

open access: yesSymbolic Interaction, EarlyView.
In this paper, we use Goffman's notion of “face work” to examine how pipeline engineers perform and present their working selves as competent experts. Our analysis identifies various faces and face work tactics, including a focus on professional judgment, actively selling one's expertise relative to others, protective self‐deprecatory strategies, and ...

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

open access: yesSymbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

Accelerating Mission Engineering: Evidence of a Stratified Landscape and a Path Toward Unified Practice

open access: yesSystems Engineering, EarlyView.
ABSTRACT Mission Engineering is maturing as a Systems Engineering discipline, yet adoption of its common frameworks remains stratified. This study examines whether selective adoption is observable across ME scholarship and develops a framework to address identified barriers.

Jamming modulation aided anti-jamming communication method based on optimized bit error ratio

open access: yesTongxin xuebao
To enhance the communication’s anti-suppressive jamming capability, a jamming modulation aided anti-jamming communication method based on optimized bit error ratio (BER) was proposed. Firstly, the system model of jamming modulation aided anti-jamming was
