Artificial Intelligences: A Bridge Toward Diverse Intelligence and Humanity's Future

open access: yesAdvanced Intelligent Systems, EarlyView.
Many discussions of artificial intelligence fail to address deeper questions being raised by advances in developmental biology, neuroscience, bioengineering, and philosophy of mind. Novel beings, including technologically and biologically augmented humans, engineered life forms, hybrots, and others, require tools of the emerging field of diverse ...

The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns

open access: yesAnnalen der Physik, EarlyView.
We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

Phenomenological constraints on Lemaitre-Tolman-Bondi cosmological inhomogeneities from solar system dynamics

open access: yes, 2010
We, first, analytically work out the long-term, i.e. averaged over one orbital revolution, perturbations on the orbit of a test particle moving in a local Fermi frame induced therein by the cosmological tidal effects of the inhomogeneous Lemaitre-Tolman ...

Gravitational Radiation Damping and the Three-Body Problem

open access: yes, 2002
A model of three-body motion is developed which includes the effects of gravitational radiation reaction. The radiation reaction due to the emission of gravitational waves is the only post-Newtonian effect that is included here.

Thermal‐Infrared Measurements of the North‐East Tower at Ardrossan Castle

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Thermal‐infrared imaging of buildings is used to investigate a range of phenomena including the accumulation of moisture. In general, the presence of moisture poses a direct danger to historic structures and must be characterized prior to any intervention.

Ultrastable One‐Dimensional Ti2S Electride Support for an Efficient and Durable Bifunctional Electrocatalyst

open access: yesCarbon Energy, EarlyView.
This study reports a stable 1D [Ti2S]2+·2e− electride as robust support for Pt catalysts, exhibiting exceptional HER and ORR activity and durability beyond Pt/C. Its unique dual‐channel anionic electron structure offers insight into electride chemistry, bridging material science and practical energy conversion applications.

Chains of rotational tori and filamentary structures close to high multiplicity periodic orbits in a 3D galactic potential

open access: yes, 2011
This paper discusses phase space structures encountered in the neighborhood of periodic orbits with high order multiplicity in a 3D autonomous Hamiltonian system with a potential of galactic type. We consider 4D spaces of section and we use the method of

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks

open access: yesChemistry–Methods, EarlyView.
The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].

Extreme Secular Excitation of Eccentricity Inside Mean Motion Resonance: Driving Small Bodies into Star-Grazing Orbits by Planetary Perturbations

open access: yes, 2017
It is well known that asteroids and comets fall into the Sun. Metal pollution of white dwarfs and transient spectroscopic signatures of young stars like $\beta$-Pic provide growing evidence that extra solar planetesimals can attain extreme orbital ...

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

open access: yesThe Depositional Record, EarlyView.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.
