Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Schaum's outline of theory and problems of Lagrangian dynamics: with a treatment of Euler's equations of motion, Hamilton's equations and Hamilton's principle

, 1967
The book clearly and concisely explains the basic principles of Lagrangian dynamicsand provides training in the actual physical and mathematical techniques of applying Lagrange's equations, laying the foundation for a later study of topics that bridge ...

Numerical Modeling of the Motion of the Flat Textile Structures

, 2011
In many problems from the field of textile engineering (e.g., fabric folding, motion of the sewing thread) it is necessary to investigate the motion of the objects in dynamic conditions, taking into consideration the influence of the forces of inertia ...

Developing a macroecology for human‐altered ecosystems

Ecography, EarlyView.
Although anthropogenically‐induced ecological disruptions are fundamentally important in defining ecosystem properties, they are largely overlooked by macroecological theory. Anthropogenic disruptions and their effects are generally not comparable to one another, nor to disturbances that are part of natural disturbance regimes.

Left Wanting and Left Unheard: A Dual Grievance Model of Populism Across Six European Countries

European Journal of Social Psychology, EarlyView.
ABSTRACT This study tests a dual grievance model of populism by examining whether relative deprivation and external political inefficacy are linked to two core dimensions of populist beliefs (people sovereignty and anti‐elitism) via aversive political emotions (anger, sadness and fear) and institutional distrust across six European countries (N = 5487).
