Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental 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.

New‐Generation Integrated Devices: Multiple‐Energy Utilization and Integration Systems Based on Perovskite Photovoltaics

open access: yesEcoEnergy, EarlyView.
This review highlights emerging integrated energy systems based on perovskite photovoltaics, including PSC–thermoelectric, photovoltaic–electrochemical, self‐charging, and building‐integrated architectures. By coupling multiple energy conversion and storage pathways, these multifunctional platforms enable enhanced solar utilization, improved stability,

Age‐related trends in niche position and specialization in Neotropical vertebrates

open access: yesEcography, EarlyView.
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

open access: yesFlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Nonlinear Elliptic Partial Difference Equations on Graphs

open access: yes, 2008
This article initiates the study of nonlinear elliptic partial difference equations (PdE) on graphs. We seek solutions u: V → R to the semilinear elliptic difference equation −Lu + f(u) = 0 on a graph G = (V, E), where L is the (negative) Laplacian on ...

Beyond political risk: Toward a holistic understanding of multinational enterprise resilience in the era of cascading crises

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary This article develops a conceptual framework for understanding multinational enterprise (MNE) resilience in the era of cascading crises. We define resilience as the MNE's capacity to absorb disruption, maintain or restore functioning, and reconfigure operations as conditions shift.

Persistence and imperfection of nonautonomous bifurcation patterns

open access: yes, 2011
For nonautonomous dynamical systems a bifurcation can be understood as topological change in the set of bounded entire solutions to a given time-dependent evolutionary equation.

Geopolitics and global strategy: Making money under anarchy

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary Multinational firms conduct cross‐border trade and investment in a world of anarchy, where nation‐states must secure their survival in the absence of a world government. We develop a geopolitical‐economic order (GEO) framework to argue that the extent of geopolitical competition incentivizes states to create one of two types ...
