Performance Art in the Age of Extinction

open access: yesPhilosophies
This paper aims to map out the transformations in contemporary performance art during the current ‘age of extinction’. The first section extends Claire Bishop’s notion of “delegated performance” in order to categorize a turn towards the inclusion of ...

Decline in extinction rates and scale invariance in the fossil record

open access: yes, 1998
We show that the decline in the extinction rate during the Phanerozoic can be accurately parameterized by a logarithmic fit to the cumulative total extinction. This implies that extinction intensity is falling off approximately as the reciprocal of time.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition

open access: yesAdvanced Functional Materials, EarlyView.
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

Island biogeography: colonization, evolution, and excitation; analogy and potential implication to oncology

open access: yesFrontiers in Ecology and Evolution
Life on islands and cancer evolves under unique environmental pressures and acquire distinctive features. This manuscript is an attempt to find analogies between carcinogenesis and island biota colonization, evolution, and extinction.

Oligohistidine‐Functionalized Single‐Walled Carbon Nanotube‐Guided RNA Delivery to Improve Shoot Regeneration Efficiency in Plant Calli

open access: yesAdvanced Functional Materials, EarlyView.
The pH‐sensitive His6‐SWNTs, which is functionalized with oligohistidine, can deliver STTM396 molecules into callus cells. The STTM396–SWNT complex treatments enhance shoot regeneration efficiency by regulating the miR396‐GRF module in Arabidopsis and tomato calli.

Computational Fluid Dynamics of Compartment Fires: A Review of Methods and Applications

open access: yesApplied Sciences
Compartment fires, such as those occurring in buildings and confined spaces, impose modeling challenges due to the complexity of turbulent flows, combustion, and radiative heat transfer.

Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.
