Photochemical Surface Degradation in Spiropyran Based Films

ChemPhotoChem, EarlyView.
Monitoring of photoswitching surface properties using molecular photochromes can give misleading results due to primary inner filter effects. The surface layer can degrade but then protect deeper layers from damage, leading to misassignment of the origin of light driven changes in surface energy.

Walking the Talk? Managing Errors in the Audit Profession*

Contemporary Accounting Research, Volume 39, Issue 4, Page 2696-2729, Winter 2022., 2022
ABSTRACT Errors reflect unintended deviations from plans or goals and commonly carry negative connotations. Although errors cannot be eliminated, they offer opportunities for learning and innovation. Audit firms employ powerful mechanisms, such as review processes, to prevent or detect audit errors and safeguard their work in the public interest.

Variability of gravitational lens images, caused by variability of gravitational field of lens: binary systems and loops of cosmic strings

Вісник Астрономічної школи, 2003
Gravitational lenses with changeable mass distribution cause characteristic changes of image brightness. Detection and analyze of such changes allow us to clarify the nature of the lens. This effect gives a possibility to obtain such dynamical objects as

Exploring Economic Conflict Through the Gravitational Field Model of Trade: Markets, Wars, and Instability

Conflict Resolution Quarterly, EarlyView.
ABSTRACT Building on Walter Isard's location and gravity theories in economics, we extend his trade model to better understand its core principles, including commercial attraction, center of gravity in markets, and favorable location for exporting firms.

Weak lensing, dark matter and dark energy

, 2010
Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe. In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion rate of ...

Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

The Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Gravitational lensing around Kehagias–Sfetsos compact objects surrounded by plasma

European Physical Journal C: Particles and Fields, 2019
We study the optical properties of the Kehagias–Sfetsos (KS) compact objects, characterized by the “Hořava” parameter $$\omega _{_{KS}}$$ ωKS , in the presence of plasma, considering its homogeneous or power-law density distribution.

Strong gravitational lensing in a squashed Kaluza-Klein black hole spacetime

, 2010
We investigate the strong gravitational lensing in a Kaluza-Klein black hole with squashed horizons. We find the size of the extra dimension imprints in the radius of the photon sphere, the deflection angle, the angular position and magnification of the ...

The role of refluxing deep hypersaline brines and evaporite precipitation dynamics in the Castile Formation and marginal carbonate strata (Delaware Basin, USA)

The Depositional Record, EarlyView.
The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...
