title: Geometric Resolution of Cosmic Tensions: A Numerical Note on Λ and H₀

description: Are the “Crisis in Cosmology” and the “Vacuum Catastrophe” simply geometric artifacts of how we parametrize Λ and H₀?  

This data note and accompanying Python script demonstrate that two of the largest anomalies in physics—the Hubble tension and the cosmological constant problem—can be numerically reproduced as simple geometric boundary conditions, without introducing new dynamical physics or free parameters.

Key findings

Hubble tension via sphere packing

  We show that the discrepancy between global (CMB) and local (SH0ES) measurements of H₀ corresponds to the geometric difference between a continuous fluid and a discrete packed structure. Applying the 3D kissing‑number packing factor (1 + 1/12) to the Planck 2018 value H₀ᴄᴍʙ = 67.4 km/s/Mpc predicts a local value of 73.02 km/s/Mpc, matching the SH0ES measurement (73.04 ± 1.04) at the level of about 0.02 standard deviations.

 

 Cosmological constant as a horizon invariant  

  We show that the apparent 10¹²² “fine‑tuning” of Λ disappears when Λ is treated as a boundary curvature term. The dimensionless product of Λ and the Hubble‑horizon area A_H reduces to an algebraic identity of order unity (~25.8), consistent with the geometric phase‑space factor 4π(π³/15) ≈ 25.98 to within about 0.7%.

title: Dangerous Harbor: Escape Attempts from Servitude and Slavery in Virginia Court Order Books, 1649-1699

description: Held on microfilm in the Library of Virginia, seventeenth-century Virginia court books record escapes and escape attempts of unfree laborers of Indigenous, European, and African descent. Colony- and county-level documents provide rich source material chronicling the evolution of legal bondage and attempts to resist it. This dataset draws from order books and deed and will books created between 1649 and 1699 from geographically contiguous Lancaster, Westmoreland, and (Old) Rappahannock Counties in Virginia. It covers recorded strategies of self-emancipation, including modes of transportation, co-conspirators, and destination, as well as the legal proceedings following such attempts including punishment, fines, court members, jury members, and other participants in the legal proceedings. Finally, the dataset includes a transcript of the text itself, enabling analysis of change over time in the language surrounding court orders and testimony. It documents a total of 745 people involved in 276 events as indentured servants, enslaved people, jury members, court members, abettors, and more.

title: Design and Implementation of a Participatory and User-Centred 5S Methodology for Manufacturing Management in Fab Labs

description: Although Fab Labs are proliferating globally, there is still little literature on their operational management, and therefore a significant research gap exists on how to adapt industrial efficiency methodologies to these collaborative and open environments. This study addresses this research gap by presenting “5S-FabLab-USER,” a participatory methodology that adapts the 5S framework (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) to these environments, integrating user feedback as the central driving force of the improvement cycle. The methodology was validated through an action research study in a university Fab Lab, focusing on the Seiri and Seiton phases. The results combine quantitative metrics of perception and operational efficiency, demonstrating that active user participation not only significantly improves perceived space organization and safety, but also facilitates the cultural adoption of Lean practices. The main novelty lies in the iterative, user-centered approach that overcomes traditional resistance to standardization in creative spaces. The findings offer laboratory managers a validated roadmap for improving operational efficiency and sustainability without sacrificing the creative flexibility inherent in these environments.

title: Data from: Population genomics of endangered lenoks (Brachymystax spp.) in China reveals the presence of cryptic species

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;Lenoks, species within the genus &lt;em&gt;Brachymystax&lt;/em&gt;, are freshwater salmonids with a scattered distribution in the rivers of Siberia, Northeast China, Xinjiang, Hebei, and the Qinling Mountains. Owing to long-term population declines, all species assigned to &lt;em&gt;Brachymystax&lt;/em&gt; are protected by law in China. However, the evolutionary history and species-level systematics of this genus remain controversial, complicating taxonomic designations and conservation efforts. In particular, the geographical separation of populations may have resulted in the formation of phenotypically similar cryptic species. We built a chromosome-level genome assembly of &lt;em&gt;B. tsinlingensis&lt;/em&gt; and re-sequenced the genomes of 103 individuals of Chinese &lt;em&gt;Brachymystax&lt;/em&gt; spp. from five geographically isolated locations. Population genomic and phylogenomic analyses based on nuclear SNPs and mitochondrial genomes revealed six different genetic lineages, of which at least one, the Hebei lineage, represents a cryptic species. Notably, the results suggest that the sympatric species &lt;em&gt;B. lenok&lt;/em&gt; and &lt;em&gt;B. tumensis&lt;/em&gt; are not close relatives, but the former is more closely related to the new species &lt;em&gt;B&lt;/em&gt;.&lt;em&gt; &lt;/em&gt;sp. Xinjiang with an estimated divergence time of c. 630 Ka, indicating that closely-related sympatric species may not have evolved via sympatric speciation in areas influenced by Pleistocene climate changes. We observed mito-nuclear phylogenomic discordance in &lt;em&gt;Brachymystax&lt;/em&gt; caused by the strong gene flow between &lt;em&gt;B. lenok&lt;/em&gt; and &lt;em&gt;B. tumensis&lt;/em&gt;. Phylogenetic and demographic analyses emphasize the important role of interglacial refugia in promoting speciation and underscore the impact of historical gene flow. Compared to other lenoks, the Gansu population had the lowest genetic diversity, suggesting that particular attention to protect its genetic resources may be required. Finally, we suggest that cross-regional proliferation and release of lenoks should be banned in the future to protect the genetic integrity of these divergent groups.&lt;/p&gt;

title: Numbers of tents of western tent caterpillars over time for six areas in British Columbia Canada and population characteristics for the population on Galiano Island

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;This paper is a historical account of the experiments and observations on the population dynamics of western tent caterpillars, &lt;em&gt;Malacosoma californicum pluviale,&lt;/em&gt; beginning in the 1975 through 2025. It contains figures of population trends and characteristics of the populations that vary with population density to show that infection by Mcplnucleopolyhedrovirus (extrinsic factor) and changes in fecundity and early larval survival (tent size) (intrinsic factors) relate to the population change. &lt;/p&gt;
description: &lt;b&gt;Methods&lt;/b&gt;&lt;br /&gt;&lt;p&gt;&lt;strong&gt;Methods - Myers_Cory_tent_caterpillar_Gulf_Islands_population_data.csv&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Since 1975, tents were counted each May on the 7 ha Mandarte Island by following a set path around the whole island and scanning for tents on all the vegetation we could see using binoculars. Over the next 10 years additional sites on other islands and locations were identified and defined areas were monitored. On Galiano Island the main site is an approximately one kilometer section of road  A second site on Galiano Island is at Montague Harbour where the host trees are primarily domestic apples, &lt;em&gt;Malus domestica&lt;/em&gt;, and wild rose. On Saturna Island, the site is a grassy area surrounded by red alder trees. The Westham site is an open field along a slough and a dyke extending westward toward the Strait of Georgia. Crab apple (&lt;em&gt;Malus diversifolia&lt;/em&gt;) and alders are the dominant host trees. Alders are also the dominant host trees on Cypress Mountain, where monitoring comprises three sites along the road up the mountain.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Methods - Myers_Cory_tent_caterpillar_Galiano_population_data.csv&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;In addition to counting the number of WTC tents annually, we monitored changes in fecundity (number of eggs per mass) and early larval survival as indicated by tent size (maximum length x width) when the larvae were in the fourth instar. In 1990, we began monitoring the levels of infection by McplNPV using DNA analysis (Kukan and Myers 1997). Beginning in 1999, NPV infection in all sites was estimated by collecting samples of 10 fourth instar larvae per tent (family) and rearing them on alder leaves in the laboratory until one larva died of viral infection or pupation occurred. The number of parasitoids emerging from the larval samples was also recorded.&lt;/p&gt;
