Population dynamics in Northeastern Brazil during the Holocene: radiocarbon evidence and climate context (code and data) Code and data to reproduce the analyses and Figs. 2–6 of the paper: random-mark permutation test by biome, Bayesian exponential and logistic growth models, posterior predictive check, Polya urn and Poisson-process changepoint models, and comparison with speleothem δ¹⁸O records. Includes the radiocarbon dataset (580 dates from 186 sites in the nine states of the Brazilian Northeast, each with its primary reference) and the cached model fits. See README.md. Licences: code under MIT, dataset and results under CC BY 4.0; third-party speleothem and biome layers keep their own terms (see LICENSE).

This dataset contains the original DSLR photographs and corresponding Agisoft Metashape 3D reconstruction for Statue 1, one of four cultural-heritage objects documented in Thessaloniki, Greece, for the study Photogrammetry with LiDAR iPad Pro. The original study compared DSLR-based photogrammetry processed on a PC with LiDAR-based 3D scanning performed on a 2021 12.9-inch M1 iPad Pro using Polycam. For Statue 1, the publication reports an Ultra-High Metashape workflow and a final PC-derived model of 3,100,244 faces. This Zenodo record preserves the DSLR image set and the corresponding surviving Metashape reconstruction, re-exported in 2026 as Wavefront OBJ with its associated MTL and JPEG texture files.

This dataset accompanies the manuscript “A 31 antibody imaging mass cytometry panel for germinal centre architecture and spatial immunophenotyping in human palatine tonsils.”  The deposit contains FCS files from imaging mass cytometry measurements of formalin-fixed, paraffin-embedded human palatine tonsil tissue. The study comprises 36 regions of interest from 25 donors and was used to characterize germinal-centre-associated architecture and immune phenotypes using a 31-antibody IMC panel.  Files: 1. classified_cells.parquet Single-cell spatial measurements for all 579,445 segmented cells across 36 ROIs and 25 donors: Spatial coordinates: centroid_x, centroid_y (µm, 1 pixel = 1 µm). Expression channels: Raw and ArcSinh-transformed mean intensities for all 31 antibodies and DNA intercalators across whole-cell and nuclear compartments. Follicle context: follicle_id, in_gc (boolean flag for confirmed germinal centre), and distance_to_gc_boundary_um. Phenotypes: Single-cell lineage and activation classifications across 13 hierarchical rules. 2. hyperion_panel.yaml Authoritative 31-antibody panel specification (Table 4): Target antigen, metal isotope, clone, vendor, catalog number, conjugate type, and working dilution. 3. models.csv Primary statistical regressions and sensitivity models: 7-day GC area ratio (0.4232, P = 0.001966), OLS t-confidence intervals, donor-bootstrap intervals, and permutation P-values

Redacted copy of the administrative decision (Bescheid) issued by the University of Potsdam, Dezernat für Personal- und Rechtsangelegenheiten, on 30 September 2026 in response to a request of 4 August 2026 by Yiftach Fehige under the "Brandenburg Akteneinsichts- und Informationszugangsgesetz" (AIG) (freedom of information law). The request sought access to records on the termination of the agreement(s) between the University of Potsdam and the Abraham Geiger Kolleg and on the University's cooperation with the Nathan Peter Levinson Stiftung. The University granted the request in part. It released Senate resolution S 4/350 of 20 May 2026 and the First Supplement (7 July 2026) to the cooperation agreement of 16 September 2024 with the Nathan Peter Levinson Stiftung, and stated that the foundation's recognition as an affiliated institute (An-Institut) has been effective since 7 July 2026. The remainder was refused on these grounds: Termination notices, the terminated agreements and the contractual clauses relied on: § 2 Abs. 4 AIG (pending proceedings). Records on the consequences for the Ständige Studienkommission: § 2 Abs. 2 S. 2 AIG (exception for science, research and teaching). Annexes and side agreements to the 2024 cooperation agreement, including the "Leitsätze für gemeinsame Berufungen": stated not to exist. Lease agreements: § 5 Abs. 1 S. 1 Nr. 3 AIG (trade secrets of the foundation). Personal data of university staff and the recipient's contact details have been redacted. The two annexes to the decision are not part of this file. The document is made available for research on the institutional governance of confessional theology at German state universities. 6 pages, German.

We investigate ordinary matter in other branches of the universal quantum state as a possible explanation of dark matter. In the Everettian interpretation, these branches describe alternative, approximately classical histories that coexist without wave-function collapse. Preferential semiclassical gravity (PSG) proposes that matter feels the full gravitational field of its own branch together with a shared field averaged over branches using their Born probabilities. All nongravitational interactions remain within each branch. The probability weighting makes laboratory falsification extremely unlikely. For cosmology, we propose a population of branches with similar initial baryon content but different photon abundances. Branches with little radiation offer a possible early source with weaker pressure. Dense clouds could subsequently cool into effectively collisionless stars and black holes while retaining their motion through larger systems. The Born-weighted distribution of this collisionless population could supply a smooth shared halo, while common gravitational wells maintain its association with galaxies and clusters. A conditional correspondence with Vlasov dynamics connects this description to established collisionless dark-matter methods. These arguments motivate PSG as a plausible explanation of dark matter without new particles. Quantitative evolution, observational comparison and a relativistic completion remain subsequent work.
