Publication Kinegami: Open-source Software for Creating Kinematic Chains from Tubular Origami(Springer, 2024-07-16) Feshbach, Daniel AdamArms, legs, and fingers of animals and robots are all examples of “kinematic chains" - mechanisms with sequences of joints connected by effectively rigid links. Lightweight kinematic chains can be manufactured quickly and cheaply by folding tubes. In recent work [Chen et al. 2023], we demonstrated that origami patterns for kinematic chains with arbitrary numbers of degrees of freedom can be constructed algorithmically from a minimal kinematic specification (axes that joints rotate about or translate along). The work was founded on a catalog of tubular crease patterns for revolute joints (rotation about an axis), prismatic joints (translation along an axis), and links, which compose to form the specified design. With this paper, we release an open-source python implementation of these patterns and algorithms. Users can specify kinematic chains as a sequence of degrees of freedom or by specific joint locations and orientations. Our software uses this information to construct a single crease pattern for the corresponding chain. The software also includes functions to move or delete joints in an existing chain and regenerate the connecting links, and a visualization tool so users can check that the chain can achieve their desired configurations. This paper provides a detailed guide to the code and its usage, including an explanation of our proposed representation for tubular crease patterns. We include a number of examples to illustrate the software’s capabilities and its potential for robot and mechanism design.Publication Re-programmable Matter by Folding: Magnetically Controlled Origami that Self-Folds, Self-Unfolds, and Self-Reconfigures On-Demand(Springer, 2024-07-24) Unger, Gabriel; Sung, CynthiaWe present a reprogrammable matter system that changes shape in a controllable manner in real-time and on-demand. The system uses origami inspired fabrication for self-assembly and repeated self-reconfiguration. By writing a magnetic program onto a thin laminate and applying an external magnetic field, we control the sheet to self-fold. The magnetic program can be written at millimeter resolution over hundreds of programming cycles and folding steps. We demonstrate how the same sheet can fold and unfold into multiple shapes using a fully automated program-and-fold process. Finally, we demonstrate how electronic components can be incorporated to produce functional structures such as a foldable display. The system has advantages over existing programmable matter systems in its versatility and ability to support potentially any folding sequence.Publication A Comparative Evaluation of the Share-VDE Search System(Taylor and Francis Group, 2024-07-03) Hahn, Jim; Ahnberg, Kayt; Giusti Serra, LilianaThe Share-VDE search system (https://svde.org) shifts the library discovery paradigm from record-based indexing and retrieval to that of linked data entity exploration. This paper reports results of iterative testing of multiple versions of the Share-VDE interface. The testing included remote user experience (UX) interviews with a total of twenty participants across four rounds of tests spanning two years. The comparison among participants encompassed catalogers, students of all levels, and faculty. Synthesizing IFLA LRM user tasks with interface evaluation methods supported the qualitative inquiry into how linked data systems in general, and BIBFRAME specifically, can support search system objectives.Publication Digital Frontlines: The Emerging Role of Cryptocurrencies in Hybrid Warfare & Geopolitics(College Undergraduate Research Electronic Journal (CUREJ), 2023-04-30) Stephanie HwangAs the digital landscape has evolved over the past several decades, scholars have noted that cyberspace has emerged as a new frontier for conflict, challenging conventional war paradigms and revealing the limitations of existing legal and normative frameworks. Amidst this evolving landscape, cryptocurrencies both present high economic promise and highlight the need for necessary safeguards to ensure that their economic potential is not compromised. This thesis delves into the potential exploitation of cryptocurrencies by the Axis of Autocracy, the subsequent consequences for the global geopolitical landscape, and the wisdom gleaned from the international community's past experiences with geopolitical destabilization. By focusing on Advanced Persistent Threats (APTs), namely North Korea's Lazarus Group, this research highlights the innovative and disruptive nature of hybrid warfare within the cryptocurrency realm. It underscores the dual-edged nature of cryptocurrencies: as instruments of significant economic empowerment and innovation, and as tools potentially manipulated in the service of hybrid warfare. The analysis scrutinizes the geopolitical threat posed by APTs’ use of crypto as a means of waging hybrid war against the West, emphasizing the importance of global collaboration and regulatory oversight to harness the full potential of cryptocurrencies while mitigating their vulnerabilities. In an era marked by the continuous blurring of boundaries between peace and conflict, this thesis offers invaluable insights and recommendations for policymakers, finance experts, and academics striving to understand and address the complexities of cybersecurity and international relations in promoting a stable global order.Publication Implicit Bias in Nursing Care: A Walker and Avant Concept Analysis(University of Pennsylvania, 2023-12) Chris Barnes, MDiv, MSN, RN, CEN, TCRN, CPENNurses address pain and suffering in their daily practice; yet, an underlying problem for nurses is the presence of implicit bias. This paper uses the Walker and Avant (2019) Concept Analysis guidelines to analyze the concept of implicit bias in nursing. The concept analysis reviewed 143 articles of which 21 articles met the inclusion criteria for understanding the impact of implicit bias in current nursing practice. Defining attributes, antecedents, consequences, and empirical referents are identified. Example cases are also offered. The concept analysis highlights the concept of implicit bias and the impact upon nursing care.
