The mystery of alpha and the isotopes
, Monthly Notices of the Royal Astronomical Society, Vol: 539, Pages: L1-L6, ISSN: 0035-8711We report unbiased Artificial Intelligence (AI) measurements of the fine structure constant α in two proximate absorption regionsin the spectrum of the quasar HE0515−4414. The data are high resolution, high signal to noise, and laser frequency combcalibrated, obtained using the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO)spectrograph on the VLT. The high quality of the data and proximity of the regions motivate a differential comparison, exploringthe possibility of spatial variations of fundamental constants, as predicted in some theories. We show that if the magnesiumisotopic relative abundances are terrestrial, the fine structure constants in these two systems differ at the 7σ level. A 3σdiscrepancy between the two measurements persists even for the extreme non-terrestrial case of 100 per cent 24Mg, if shared byboth systems. However, if Mg isotopic abundances take independent values in these two proximate systems, one terrestrial, theother with no heavy isotopes, both can be reconciled with a terrestrial α, and the discrepancy between the two measurementsfalls to 2σ. We cannot rule out other systematics that are unaccounted for in our study that could masquerade as a varyingalpha signal. We discuss varying constant and varying isotope interpretations and resolutions to this conundrum for future highprecision measurements.

Terrestrial Very-Long-Baseline Atom Interferometry: summary of the second workshop
, EPJ Quantum Technology, Vol: 12, ISSN: 2196-0763This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024 (Second Terrestrial Very-Long-Baseline Atom Interferometry Workshop, Imperial College, April 2024), building on the initial discussions during the inaugural workshop held at CERN in March 2023 (First Terrestrial Very-Long-Baseline Atom Interferometry Workshop, CERN, March 2023). Like the summary of the first workshop (Abend et al. in AVS Quantum Sci. 6:024701, 2024), this document records a critical milestone for the international atom interferometry community. It documents our concerted efforts to evaluate progress, address emerging challenges, and refine strategic directions for future large-scale atom interferometry projects. Our commitment to collaboration is manifested by the integration of diverse expertise and the coordination of international resources, all aimed at advancing the frontiers of atom interferometry physics and technology, as set out in a Memorandum of Understanding signed by over 50 institutions (Memorandum of Understanding for the Terrestrial Very Long Baseline Atom Interferometer Study).

Enhancing foresight models with network science: measuring innovation feedbacks within the Chain-Linked Model
, Technological Forecasting and Social Change, Vol: 213, ISSN: 0040-1625A granular understanding of innovation dynamics is crucial for forecasting how and when different actors within the innovation system can make valuable contributions. Existing theoretical foundations of the foresight practice are largely qualitative and often oversimplify the innovation process. While foresight practitioners acknowledge the existence of knowledge feedback loops, these feedback loops are rarely quantified systematically in empirical forecasting studies. Innovators and funders tend to choose their dyadic relationships but rarely have visibility over the wider, dynamic innovation network. This study enriches innovation theories for the foresight practice by leveraging multilayer citation networks to explore innovation translation pathways, achieved by integrating data from market entries, clinical trials, patents, publications, funders, and grants over a 70-year period. Our analysis shows shifts in the order, prevalence, and tipping points of translation activities as technologies mature, with granularity not described in previous studies. We also examine the distinct funding patterns of major public and private entities throughout this maturation process, revealing their unique contributions and enriching sociotechnical explanations of innovation processes. This study improves the explainability of technology forecasting through innovation theories by reconstructing micro-technical innovation dynamics from first principles.

Learning 3-manifold triangulations
, Journal of Physics A: Mathematical and Theoretical, Vol: 58, Pages: 095201-095201, ISSN: 1751-8113<jats:title>Abstract</jats:title> <jats:p>Real 3-manifold triangulations can be uniquely represented by isomorphism signatures. Databases of these isomorphism signatures are generated for a variety of 3-manifolds and knot complements, using SnapPy and Regina, then these language-like inputs are used to train various machine learning architectures to differentiate the manifolds, as well as their Dehn surgeries, via their triangulations. Gradient saliency analysis then extracts key parts of this language-like encoding scheme from the trained models. The isomorphism signature databases are taken from the 3-manifolds’ Pachner graphs, which are also generated in bulk for some selected manifolds of focus and for the subset of the SnapPy orientable cusped census with <jats:inline-formula> <jats:tex-math/> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:mo><</mml:mo> <mml:mn>8</mml:mn> </mml:mrow> </mml:math> </jats:inline-formula> initial tetrahedra. These Pachner graphs are further analysed through the lens of network science to identify new structure in the triangulation representation; in particular for the hyperbolic case, a relation between the length of the shortest geodesic (systole) and the size of the Pachner graph’s ball is observed.</jats:p>

Analysis of polarized dust emission using data from the first flight of SPIDER
, The Astrophysical Journal: an international review of astronomy and astronomical physics, Vol: 978, ISSN: 0004-637XUsing data from the first flight of Spider and from the Planck High Frequency Instrument, we probe the properties of polarized emission from interstellar dust in the Spider observing region. Component-separation algorithms operating in both the spatial and harmonic domains are applied to probe their consistency and to quantify modeling errors associated with their assumptions. Analyses of diffuse Galactic dust emission spanning the full Spider region demonstrate (i) a spectral energy distribution that is broadly consistent with a modified-blackbody (MBB) model with a spectral index of βd = 1.45 ± 0.05 (1.47 ± 0.06) for E (B)-mode polarization, slightly lower than that reported by Planck for the full sky; (ii) an angular power spectrum broadly consistent with a power law; and (iii) no significant detection of line-of-sight polarization decorrelation. Tests of several modeling uncertainties find only a modest impact (∼10% in σr) on Spider’s sensitivity to the cosmological tensor-to-scalar ratio. The size of the Spider region further allows for a statistically meaningful analysis of the variation in foreground properties within it. Assuming a fixed dust temperature Td = 19.6 K, an analysis of two independent subregions of that field results in inferred values of βd = 1.52 ± 0.06 and βd = 1.09 ± 0.09, which are inconsistent at the 3.9σ level. Furthermore, a joint analysis of Spider and Planck 217 and 353 GHz data within one subregion is inconsistent with a simple MBB at more than 3σ, assuming a common morphology of polarized dust emission over the full range of frequencies. This evidence of variation may inform the component-separation approaches of future cosmic microwave background polarization experiments.

The causal set approach to the problem of quantum gravity
, Handbook of Quantum Gravity, Pages: 2989-3002Causal set theory (CST) is an approach to the problem of quantum gravity based on the twin hypotheses of fundamental spacetime discreteness and primitivity of the spacetime causal relation. We situate the chapters in the CST section of the Handbook of Quantum Gravity within the landscape of research in CST.
