SΔϕ-60 — Utilitarian Subject-Splitting Index

Sofience · 2026 · Zenodo (CERN European Organization for Nuclear Research)

SΔϕ-60 introduces the Utilitarian Subject-Splitting Index, USSI, within the Sofience-Δϕ Formalism. The paper examines whether utilitarian calculation merely evaluates the happiness of already-existing majorities and minorities, or whether such calculation can first produce the operational boundary between majority and minority by redistributing Transition Completion Cost, TCC. The document begins with the Sofience Subject Thought Experiment. A person is imagined as capable of detaching and reattaching any part of the body while the detached parts remain alive, neurologically connected, and phy

The Added Value of Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography to Magnetic Resonance Imaging for Local Staging of Prostate Cancer in Patients Undergoing Radical Prostatectomy

Timo F. W. Soeterik, Joris G. Heetman, Rick Hermsen et al. · 2024 · European Urology Oncology

BACKGROUND AND OBJECTIVE: The role of prostate-specific membrane antigen (PSMA)-based positron emission tomography (PET)/computed tomography (CT) in addition to magnetic resonance imaging (MRI) for local staging of prostate cancer (PC) has been poorly addressed so far. Our aim was to assess the diagnostic accuracy of PSMA PET/CT and MRI, alone and combined, for detection of extraprostatic extension (EPE) and seminal vesicle invasion (SVI) in PC. METHODS: We conducted a multicenter retrospective study evaluating patients undergoing PSMA PET/CT and MRI before radical prostatectomy. The sensitivi

Retrograde Interference in Perceptual Learning of a Peripheral Hyperacuity Task

Shao-Chin Hung, Aaron R. Seitz · 2011 · PLoS ONE

Consolidation, a process that stabilizes memory trace after initial acquisition, has been studied for over a century. A number of studies have shown that a skill or memory must be consolidated after acquisition so that it becomes resistant to interference from new information. Previous research found that training on a peripheral 3-dot hyperacuity task could retrogradely interfere with earlier training on the same task but with a mirrored stimulus configuration. However, a recent study failed to replicate this finding. Here we address the controversy by replicating both patterns of results, ho

Mutualism breakdown underpins evolutionary rescue in an obligate cross-feeding bacterial consortium

Ignacio J. Melero‐Jiménez, Yael Sorokin, Ami Merlin et al. · 2025 · Nature Communications

Populations facing lethal environmental change can escape extinction through rapid genetic adaptation, a process known as evolutionary rescue. Despite extensive study, evolutionary rescue is largely unexplored in mutualistic communities, where it is likely constrained by the less adaptable partner. Here, we explored empirically the likelihood, population dynamics, and genetic mechanisms underpinning evolutionary rescue in an obligate mutualism involving cross-feeding of amino acids between auxotrophic Escherichia coli strains. We found that over 80% of populations overcame a severe decline whe

Impact of transfer learning methods and dataset characteristics on generalization in birdsong classification

Burooj Ghani, Vincent J. Kalkman, Bob Planqué et al. · 2025 · Scientific Reports

Animal sounds can be recognised automatically by machine learning, and this has an important role to play in biodiversity monitoring. Yet despite increasingly impressive capabilities, bioacoustic species classifiers still exhibit imbalanced performance across species and habitats, especially in complex soundscapes. In this study, we explore the effectiveness of transfer learning in large-scale bird sound classification across various conditions, including single- and multi-label scenarios, and across different model architectures such as CNNs and Transformers. Our experiments demonstrate that

Identifying statistically significant combinatorial markers for survival analysis

Raissa Relator, Aika Terada, Jun Sese · 2018 · BMC Medical Genomics

BACKGROUND: Survival analysis methods have been widely applied in different areas of health and medicine, spanning over varying events of interest and target diseases. They can be utilized to provide relationships between the survival time of individuals and factors of interest, rendering them useful in searching for biomarkers in diseases such as cancer. However, some disease progression can be very unpredictable because the conventional approaches have failed to consider multiple-marker interactions. An exponential increase in the number of candidate markers requires large correction factor

The proposal distribution used in the calibration stage is obtained via a Population Monte Carlo scheme with tempering and relies on flexible parametric variational families such as normalizing flows. Once the calibration stage complete, the resulting algorithm defines a homogeneous Markov chain via a mixture of HMC kernels with a fixed mixing distribution, and hence preserves the target distr

Evolutionary assembly of crown reptile anatomy clarified by late Paleozoic relatives of Neodiapsida

Xavier A. Jenkins, Roger Benson, David P. Ford et al. · 2025 · Peer Community Journal

Living reptiles include more than 20,000 species with disparate ecologies. Direct anatomical evidence from Neodiapsida, which includes the reptile crown-group and its closest extinct relatives, shows that this diversity originates from a single common ancestor that lived over 255 million years ago in the Paleozoic. However, the evolutionary assembly of crown reptile traits is poorly understood due to the lack of anatomically close relatives of Neodiapsida. We present a substantially revised phylogenetic hypothesis, informed by new anatomical data from high-resolution synchrotron tomography of

Resolving a heated debate: The utility of prescribed burning as a management tool for biodiversity on lowland heath

Barbara Smith, Dan Carpenter, J. M. Holland et al. · 2023 · Journal of Applied Ecology

Abstract Lowland heath is a priority habitat for conservation, nowadays largely managed for biodiversity. Historically, prescribed burning has been the principal management tool, but there are increasing calls to substitute burning with cutting to improve biodiversity outcomes. However, poor understanding of potential impacts compromises decision making. Our study was carried out in the New Forest National Park, the largest area of lowland heath in Europe. Using a multi‐trophic approach, we compared the ecological impact of prescribed burning with two types of vegetation cutting (swiping and b

Data visualization for inference in tomographic brain imaging

Cyril Pernet, Christopher R. Madan · 2019 · European Journal of Neuroscience

Tomographic imaging (i.e. magnetic resonance imaging [MRI], positron emission tomography [PET], X-ray computed tomography [CT]) offers a unique window in understanding structure-function relationships in the living brain. Nowadays, it is standard practice to acquire entire brain volumes and perform statistical analyses at each voxel, an approach known as statistical parametric mapping (Friston, Frith, Liddle, & Frackowiak, 1991). Because it is impossible to report the statistical results in every voxel, summary tables and figures are of importance. The choice made by authors to create such fig

HIV-1 adapts to lost IP6 coordination through second-site mutations that restore conical capsid assembly

Alex B. Kleinpeter, Donna L. Mallery, Nadine Renner et al. · 2024 · Nature Communications

The HIV-1 capsid is composed of capsid (CA) protein hexamers and pentamers (capsomers) that contain a central pore hypothesised to regulate capsid assembly and facilitate nucleotide import early during post-infection. These pore functions are mediated by two positively charged rings created by CA Arg-18 (R18) and Lys-25 (K25). Here we describe the forced evolution of viruses containing mutations in R18 and K25. Whilst R18 mutants fail to replicate, K25A viruses acquire compensating mutations that restore nearly wild-type replication fitness. These compensating mutations, which rescue reverse t

The Effort-Expenditure for Rewards Task (EEfRT) has gained validity evidence from several studies. However, various modifications have been applied to the original version, which have never been compared systematically. In Study 1, we tested 120 healthy participants to directly compare two versions of the EEfRT. In Study 2, we tested a larger sample of 394 healthy participants to further examine the original EEfRT. We replicated the split-half reliability of both task versions. However, self-reported personality traits (e.g., trait BAS) correlated with only some task performance parameters in
