kGamma distributions in granular packs

It has been recently pointed out that local volume fluctuations in granular packings follow remarkably well a shifted and rescaled Gamma distribution named the kGamma distribution [T. Aste, T. Di Matteo, Phys. Rev. E 77 (2008) 021309]. In this paper we confirm, extend and discuss this finding by supporting it with additional experimental and simulation data.Comment: 10 pages, 5 figure

Exploring Energy, Trauma, and Healing from Anchorage to Maui

Luke Delaney interviews grandmother Suzanne Angelus, sharing her thoughts on energy, historical events, and personal spiritual experiences. Defining "subtle energy" as carried and radiated by the soul, Suzanne explains how her background in acupuncture and hypnosis released emotional traumas, including those from past lives. She reflects on living in Anchorage during Alaska’s oil boom, her father's work with the Federal Aviation Administration, and her involvement in real estate and politics. Suzanne recounts her experience during the 1964 Alaska earthquake, describing the devastation and challenges of survival. She also recalls her journey to Maui in the late 1970s, exploring alternative medicine and becoming certified in hypnosis. Suzanne touches on her trip to Moscow during the Cold War and surviving the Chernobyl disaster. A firm believer in past life regression, Suzanne discusses how these spiritual insights help sever generational patterns of trauma. She also expresses her distrust of nuclear energy and concern over its environmental impact

THE IDENTITY CRISIS OF THE 01XX MOS: WHO ARE THEY AND WHY ARE THEY NEEDED TO WIN THE FIGHT?

The 01xx MOS, specifically the 0102, 0170 and 0111 OccFld in the USMC, faces an identity crisis of its current and future role within the organization. This qualitative study employs conceptual themes to analyze the historical, functional, organizational, and technological dimensions of the 01xx OccFld while using SWOT analysis to provide courses of actions for the future of the community. Findings of the 01xx OccFld reveal strengths such as historical legacy and continuous community adaptation, but weaknesses include structural disparities, lack of continuity in administrative practices, and slow policy changes. Opportunities lie in curriculum adjustments, 01xx survey feedback, and technological integration, yet threats like leadership advocacy gaps, rise of artificial intelligence, and civilianization of billets and historical biases persist. Recommendations include enhancing the technological proficiency of the 01xx Marines, balancing the Personnel Administration School curriculum with all four pillars of administration and the 01xx’s role within the Marine Corps organization, and advocating for leadership representation beyond the rank of Lieutenant Colonel within Manpower and Reserve Affairs. In conclusion, proactive adaptation is essential to ensure the 01xx Occupational Fields’ continued relevance and effectiveness in meeting the evolving needs of the Marine Corps today, tomorrow, and for the future fight.Distribution Statement A.

The importance of the electronic contribution to linear magnetoelectricity

We demonstrate that the electronic contribution to the linear magnetoelectric response, usually omitted in first-principles studies, can be comparable in magnitude to that mediated by lattice distortions, even for materials in which responses are strong. Using a self-consistent Zeeman response to an applied magnetic field for noncollinear electron spins, we show how electric polarization emerges in linear magnetoelectrics through both electronic- and lattice-mediated components -- in analogy with the high- and low-frequency dielectric response to an electric field. The approach we use is conceptually and computationally simple, and can be applied to study both linear and non-linear responses to magnetic fields.Comment: 5 pages, 3 figure

Combining tomographic imaging and DEM simulations to investigate the structure of experimental sphere packings

We combine advanced image reconstruction techniques from computed X-ray micro tomography (XCT) with state-of-the-art discrete element method simulations (DEM) to study granular materials. This "virtual-laboratory" platform allows us to access quantities, such as frictional forces, which would be otherwise experimentally immeasurable.Comment: 20 pages, 17 figure
