Operator type expansion-compression fixed point theorem

Electronic Journal of Differential Equations, 2011
This article presents an alternative to the compression and expansion fixed point theorems of functional type by using operators and functions to replace the functionals and constants that are used in functional compression and expansion fixed point ...

Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

Advanced Intelligent Discovery, EarlyView.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

No pseudosynchronous rotation for terrestrial planets and moons

, 2013
We reexamine the popular belief that a telluric planet or satellite on an eccentric orbit can, outside a spin-orbit resonance, be captured in a quasi-static tidal equilibrium called pseudosynchronous rotation.

Automated Bacterial Identification and Morphological Feature Analysis in Low‐Dose Cryo‐EM Using YOLOv11

Advanced Intelligent Discovery, EarlyView.
AI‐based tools enable rapid characterization of bacterial ultrastructure in low‐dose cryogenic transmission electron microscopy. The envelope thickness tool quantifies membrane thickness and anisotropy. The flagella module analyzes filament morphology and detects cell‐flagella contacts.

Symmetric positive solutions for $\phi$-Laplacian boundary-value problems with integral boundary conditions

Electronic Journal of Differential Equations, 2013
In this article, we study the existence, multiplicity, and nonexistence of symmetric positive solutions for a class of four-order integral boundary value problems with $\phi$-Laplacian operator.

The rain feels different under the same umbrella: Experiences with poverty across LGBTQ subgroups

American Journal of Community Psychology, EarlyView.
Abstract Population‐based survey data have demonstrated that LGBTQ communities report varying rates of economic insecurity, yet very little research directly assesses how pathways into and experiences with poverty look different among subgroups at the intersections of sexual orientation and gender identity (SOGI).

Quantum Gravity in Large Dimensions

, 2005
Quantum gravity is investigated in the limit of a large number of space-time dimensions, using as an ultraviolet regularization the simplicial lattice path integral formulation. In the weak field limit the appropriate expansion parameter is determined to

Racism and racial disparities in firearm violence: A scoping review

American Journal of Community Psychology, EarlyView.
Abstract Firearm violence (i.e., interpersonal, police firearm violence) disproportionately affects racially minoritized communities. Researchers recently shifted their focus from race to racism to better understand the factors that contribute to racial disparities in firearm violence.

Towards the graviton from spinfoams: the complete perturbative expansion of the 3d toy model

, 2008
We consider an exact expression for the 6j-symbol for the isosceles tetrahedron, involving integrals over SU(2), and use it to write the two-point function of 3d gravity on a single tetrahedron as a group integral.
