From mystery to modulation: the structural story of Rb2[Si2O5]

open access: yesActa Crystallographica Section B, EarlyView.
The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

What in the World Are 4D Shapes?

open access: yesNoûs, EarlyView.
ABSTRACT It is often said that in special relativity, 4D shapes can be used to explain 3D shape projections onto frames of reference. Perdurantists have frequently used this as a motivation for their view of persistence. Despite this, philosophers never clearly state what 4D shapes are.

Jet Injections With Candida Antigen for Wart Treatment: An Alternative Drug Delivery

open access: yesPediatric Dermatology, EarlyView.
ABSTRACT Warts are a common pediatric condition caused by human papillomavirus. Immunotherapy is a well‐studied treatment for warts and is classically administered via intralesional injection with a syringe and needle. We report a case of warts in a 12‐year‐old boy who achieved complete resolution following two sessions of pain‐free, and needleless ...

Beyond the Adult Mind: A Developmental Framework for Predictive Processing in Infancy

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Predictive Processing has been proposed as the single unifying computation underlying all of cognition, and proponents argue that all psychological phenomena can be explained as consequences of this principle. This theoretical framework has inspired many cognitive scientists and neuroscientists, but it currently has no developmental mechanism ...

Achieving Ultra‐Low Megahertz Loss in Nanocrystalline Magnetic Powder Cores via Alloy Design and a Self‐Healing Organic–Inorganic‐Derived Hybrid Insulating Layer

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 2, December 2026.
A novel self‐healing FePO4/B2O3/epoxy hybrid insulating layer is designed for high‐frequency Fe‐based nanocrystalline magnetic powder cores. During 530°C annealing, the low‐melting‐point B2O3 softens, flowing into micro‐cracks formed within the brittle FePO4 framework during cold pressing. This in situ gap‐filling mechanism effectively suppresses inter‐

A New Take on Sharp Cracks in Brittle Dielectrics: Where Electric Dipole Layers Meet Concentrated Line Forces

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT In this work, novel electrostatic aspects of sharp cracks in brittle dielectrics are discussed using the example of an impermeable Griffith crack in an infinite linear isotropic dielectric plate. On the one hand, electrostatic force densities stemming from the Maxwell stress tensor according to Lorentz are derived mathematically, where the ...

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 43, November 15, 2026.
Varnish effectiveness in plasticized PVC strongly depends on both formulation and degradation state. A polyurethane varnish effectively limits color change and plasticizer loss in unaged PVC without phosphate plasticizers, whereas no protective effect is observed for phosphate‐containing PVC.

DoseRAD2026: A benchmark dataset for AI‐accelerated photon and proton dose calculation in radiotherapy

open access: yesMedical Physics, Volume 53, Issue 11, November 2026.
Abstract Purpose Accurate dose calculation is a fundamental component of modern radiotherapy, enabling precise tumor irradiation while sparing surrounding healthy tissue. With the increasing adoption of magnetic resonance imaging (MRI)‐guided radiotherapy and growing interest in real‐time adaptive radiotherapy, there is a demand for fast and accurate ...
