Enhanced optical and infrared activity of subwavelength metal nanoparticles is key to their use in optoelectronics, spectroscopy, and sensing. The present work compared spectra of nanosphere dimers merged by centrifuging gold nanospheres with corresponding simulated nanoscale dimers. Geometric features of the nanosphere dimers were related to corresponding optical and near-infrared activity through simulation. Differences in optical and infrared activity of the nanosphere dimers were largely attributable to changes in the radius of the nanosphere and the radius of the conductive junction between merged nanospheres. The features observed in the experimental spectra were attributed to a select number of dimers exhibiting …

Multimodal Boiling Dataset With Synchronized Acoustic, Optical, And Thermal Measurements Under Steady-State And Transient Heat Loads, Hari Pandey, Changgen Li, Han Hu

Boiling is a high-performance heat dissipation process that is central to electronics cooling and power generation. However, there exists a practical limit of boiling heat transfer known as the critical heat flux (CHF), beyond which significant performance degradation is observed. Understanding the physical mechanism that triggers CHF is essential to meet the increasing cooling demands driven by power densification and device miniaturization. However, the high dimensionality, stochasticity, and dynamicity of the boiling process have led to strong challenges in the experimental characterization and modeling of boiling CHF. As such, high-frame rate, high-resolution, multi-physics boiling datasets are critical to advancing the …

2023 Transportation Electrification Scorecard: Mountain West States, Ayda Atici, Kristian Thymianos, Caitlin J. Saladino, William E. Brown Jr.
Transportation & Infrastructure
This fact sheet examines data on policies and actions to support electric vehicle (EV) infrastructure in five Mountain West states: Arizona, Colorado, Nevada, New Mexico, and Utah. The data are retrieved from the “2023 Transportation Electrification Scorecard,” created by the American Council for an Energy-Efficient Economy (ACEEE). The Scorecard measures which Mountain West states are the most efficient in progress made towards the electrification of vehicles.

American Sanctions On China's Space Program: Effective Economic Statecraft?, Paul J. Bolt
Space and Defense
American economic statecraft as a tool to manage competition with China’s Space Program is likely to remain contentious as it amplifies enduring debates in U.S. foreign policy: i) the tension between international realism and American liberalism; ii) the questionable benefit of government involvement in picking winners and losers from the private sector; and iii) the difficulty of defining long-term success in foreign policy outcomes.

Pushing Boundaries: Feminism, Female Leaders, And The Fate Of Feminist Foreign Policy, Sannia Abdullah
Space and Defense
The study challenges the clearest, unqualified liberal claim on feminist foreign policy: namely, women equal peace and security while men equal war. In fact, women approach foreign policy challenges as judiciously as men and have proven their statesmanship. Feminist foreign policy promotes gender equality, women empowerment, and socio-economic parity based on a non-hierarchal system, but it fails to offer a resilient, conflict preventing, and environmentally friendly alternative framework capable of reducing contemporary foreign policy challenges.

Atrocity Prevention In The Digital Era: Adapting Norms, Laws, And Code To Changes In The Ways Atrocities Are Committed,

Atrocity Prevention In The Digital Era: Adapting Norms, Laws, And Code To Changes In The Ways Atrocities Are Committed, David J. Simon, Samhitha Josyula, Joshua Lam, Julian D. Melendi
Genocide Studies and Prevention: An International Journal
Emerging digital technologies have changed some of the ways that genocides are planned and executed. This paper examines those differences, calling attention to how changes in the execution of genocide should prompt a shift in the approaches to atrocity prevention. It develops a conceptual framework addressing how atrocity prevention efforts might adapt to new technology within three realms of potential prevention efforts: the ethical (norms), the legal (laws), and the digital (code).

Security Or Vulnerability? The Optics Of Data In The Humanitarian Sphere, Nicole M. Bennett, Hamid Ekbia
Genocide Studies and Prevention: An International Journal
Governments, humanitarian agencies, and non-government organizations increasingly resort to data-driven techniques to meet the challenges they face in dealing with growing mobile populations such as refugees. Such techniques originate in bureaucratic administrations of the 19th century and, even earlier, in slave trade and plantation accounting methods. They were then perfected in logistics and global supply chain management of the twentieth and twenty-first centuries, especially with the advent of information technology. We examine the application of these techniques in humanitarian cases, seeking to contextualize them within the framework of logistic security. To understand the drivers of this trend, we introduce the …

Writing About A Stressful Experience Can Impair Visual Working Memory, Colton Hunter, Grant S. Shields
Psychological Science Faculty Publications and Presentations
Acute stress has been well-established to impair working memory. However, less is known about how writing about an unresolved stressor may influence working memory or working memory processes. We addressed these issues in the present study (N = 282) by randomly assigning participants to write about an unresolved stressful experience (stressful writing condition or the events of the previous day). We then both measured performance on a change detection task and used computational modeling to estimate the processes underlying performance: attention, capacity, and guessing bias. We found that, relative to the control condition, writing about a stressful experience impaired …
