Lake County, Tennessee, in the Heart of the New Madrid Seismic Zone

open access: yesFrontiers in Earth Science, 2019
Lake County, Tennessee, lies within the center of the New Madrid seismic zone, and thus is particularly vulnerable to seismic hazards. To better evaluate the seismic threat to Lake County, the stratigraphy and structure were mapped beneath the county.

Ninebrane structures [PDF]

open access: yes, 2015
String structures in degree four are associated with cancellation of anomalies of string theory in ten dimensions. Fivebrane structures in degree eight have recently been shown to be associated with cancellation of anomalies associated to the NS5-brane ...

Equilibrium of truss and beam structures of inelastic materials

open access: yesJournal of Civil Engineering and Management, 2017
A physically based method for the determination of equilibrium for structures with inelastic response is described. The method is based on minimisation of the potential energy.

Generalized Jacobi structures [PDF]

open access: yes, 1997
Jacobi brackets (a generalization of standard Poisson brackets in which Leibniz's rule is replaced by a weaker condition) are extended to brackets involving an arbitrary (even) number of functions.

Structures and Structural Realism [PDF]

open access: yesLogic Journal of the IGPL, 2005
Summary: The `ontic' form of structural realism (OSR), roughly speaking, admits a complete elimination of the objects in the discourse of scientific theories, leaving us with structures only. As put by the defenders of such a claim, the idea is that all there is are structures and, if the relevant structures are to be set-theoretical constructs ...

Mental Structures [PDF]

open access: yes, 2020
An ongoing philosophical discussion concerns how various types of mental states fall within broad representational genera—for example, whether perceptual states are “iconic” or “sentential,” “analog” or “digital,” and so on.

Tables and the Development of Computational Thinking in Programming with Emil for Primary School

open access: yesInformatics in Education
Tables are fundamental tools for handling data and play a crucial role in developing both computational thinking (CT) and mathematical thinking (MT). Despite this, they receive limited attention in research and design.
