The Age of Questions: Truth Regimes and Subjectivity in the Era of Large Language Models

Behavioral Sciences &the Law, EarlyView.
ABSTRACT This essay explores how digital technologies shape subjectivity's infra‐political constitution, focusing on large language models (LLMs) like ChatGPT or Gemini within what philosophers, inspired by Michel Foucault, term the “digital truth regime.” After defining this regime, the essay identifies five key traits of LLMs: presentism in truth ...

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

Clinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

The life and work of Ernest Sydney Keeping

Canadian Journal of Statistics, EarlyView.
Abstract This article reviews the life and contributions of Ernest S. Keeping (1895–1984), a British‐born physicist who became a mathematics professor at the University of Alberta in 1929. He played a pivotal role in shaping the university's Mathematics Department, serving as its head from 1954 to 1961, and continuing to teach until 1970, nine years ...

Talin1 Adhesion Morphology and Colocalization With Tensin3 Are Largely Unaffected by Polyacrylamide Substrate Stiffness

Cytoskeleton, EarlyView.
ABSTRACT Cells sense the stiffness of their extracellular matrix (ECM) and adapt their behavior accordingly. We investigated how ECM stiffness affects the spatial organization of talin1, a key mechanosensitive focal adhesion protein. Using polyacrylamide (PA) hydrogels with tunable stiffnesses (0.2–188 kPa), we analyzed cell morphology, migration ...

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

Developmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...
