A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

British Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.

Estimating Gravity Models of International Trade with Correlated Time-Fixed Regressors: To IV or not IV? [PDF]

Gravity type models are widely used in international economics. In these models the inclusion of time-fixed regressors like geographical or cultural distance, language and institutional (dummy) variables is often of vital importance e.g.

Emergent Gravity, Biological Intelligence, and Standard Model Predictions from Möbius-Coupled Doubly Stochastic Lattices

Building on the M¨obius–Lorentz correspondence (Foss, 2026 [1]), we investigate the dynamics ofN×N lattices of doubly stochastic 4 ×4 matrix eigenvalues coupled via f(λ,v) = (λ+ v)/(1 + λv).Three classes of emergent phenomena are established: (i) Gravitational collapse.

Validated computational modeling to evaluate spatial inactivation of airborne pathogens by Far‐UVC irradiation

Photochemistry and Photobiology, EarlyView.
Inactivation trajectories of virus‐laden particles in rooms with different ventilation rates as they move under the light of a variety of Far‐UVC devices. Abstract Recent experimental studies have indicated the potential for ultraviolet C irradiation at 222 nm (Far‐UVC) to be used in occupied rooms to safely reduce exposure to airborne pathogens.

Preprint №8: Gravity as a Radial Gradient of Lattice Tension: A Mechanical Model of Universal Attraction in the Quantum Monolith

General Relativity describes gravity as a geometric curvature of space-time. Within the HiggsField Tessellation (HPT) framework, we propose a deterministic mechanical alternative: gravity isthe result of a radial strain gradient (∇σ) within the 14-faced Kelvin cell lattice.

The Interrelated Mathematics Learner Identities and Mathematics Teacher Identities of Preservice Elementary Teachers

School Science and Mathematics, EarlyView.
ABSTRACT Despite consistent efforts for change in mathematics education aligned with ambitious and equitable teaching practices, many preservice teachers continue to enroll in teacher‐preparation programs having learned mathematics in traditional, teacher‐centered ways. If mathematics teacher educators are to support preservice teachers in breaking the

Multiscale Modelling of Frame Structures With Lattice‐Like Mesostructures Using Finite Beam Elements at the Macro and Meso Level

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT In this contribution, we present a FE2${\rm FE}^2$ model for shear‐flexible beams with a lattice‐like meso structure. The meso structure consists of a network of beams. The meso ‐ and macroscale are coupled by means of the Hill–Mandel condition.
