Preliminary clinical changes during use of a personalized video-based mobile intervention for community-dwelling individuals with severe mental illness: An exploratory randomized crossover trial

Severe mental illness (SMI) often limits participation in traditional therapy due to motivational and cognitive deficits. We examined short-term clinical changes during use of a personalized video-based mobile app ( MARO )—providing psychoeducation, emotion regulation, cognitive...

Cosmological General Relativity Black Holes:Kerr vs Kerr-Newman Dynamical Embedding, Conformal Structure, Heat Flux, Anisotropic Stress, Self-Consistent dM/dt=H(t)M(t) and Linear Coupling k=1 versus k=3 Vacuum Coupling and JWST Overmassive SMBHs

We present the complete dynamical embedding of Kerr (Q=0) and Kerr-Newman black holes in Cosmological General Relativity (CGR) defined by.

Evaluation of the physicomechanical properties and biocompatibility of low-viscosity denture base resins for 3D printing

Three-dimensional (3D) printing has rapidly emerged as a transformative manufacturing technology in prosthodontics. However, the clinical application of 3D-printed denture base resins remains limited by insufficient mechanical properties and high viscosity. This study evaluated t...

Cosmological General Relativity Black Holes: A Consolidated and Independently Verified Treatment of Kerr and Kerr-Newman Dynamical Embedding

This paper consolides and fixes the definitive status of the conformal embedding, of Kerr and Kerr-Newman black holes in Cosmological General Relativity (CGR), superseding several earlier drafts in which corrections established by independent verification were repeatly omitted on...

Dynamical Embedding of Kerr-Newman-de Sitter Spacetime in Cosmological General Relativity:An Indepedently Verified Analysis of Heat Flux, the Mass-Growth Ambiguity, and Cosmologically Coupled Black Holes

We revisit the conformal embedding of static Kerr-Newman-de Sitter(KNdS) spacetime into Cosmological General Relativity(CGR), and subject its central claims to independent symbolic verification and to comparison with the pre-existing "cosmologically coupled black hole"(CCBH) lite...

Dynamical Embedding of Kerr-Newman-de Sitter Spacetime in Cosmological General Relativity:Heat Flux, Anisotropic Stress, Self-Consistent Verification of dM/dt=HM and Linear Cosmological Coupling k=1 for JWST Overmassive Black Holes

We present the rigorous distinction between static Kerr-Newman-de Sitter (KNdS) thermodynamics with cosmological constant and dynamical embedding in Cosmological General Relativity (CGR) with expansion factor a(t) and Hubble parameter H.

Can semiclassical Particle Creation Justified dM/dt=+HM? An Adiabatic Estimate for the CGR-Embedded Black Hole

A companion analysis of the Kerr-Newman-de Sitter Embedding in Cosmological General Relativity(CGR) identified an unresolved ambiguity:the field equations admit both dM/dt=-2HM(choice A) and dM/dt=+HM(choice B), with no criterion internal to CGR selecting between them.

Cosmological Special Theory of Relativity: Lorenz Gauge, Uniformly Accelerated Frames, Proper Distance and Fermi-Walker Transfort II:Electromagnetic Sector

We present the extension of the Cosmological Special Theory of Relativity (CSTR) to the electromagnetic sector with emphasis on the Lorenz gauge condition, uniformly accelerated frames and proper distance.
