A method of predicting quasi-steady aerodynamics for flutter analysis of high speed vehicles using steady CFD calculations

, 1993
High speed linear aerodynamic theories like piston theory and Newtonian impact theory are relatively inexpensive to use for flutter analysis. These theories have limited areas of applicability depending on the configuration and the flow conditions.

Shared foraging behaviors between hyenas and hominins in the Middle Paleolithic Levant: New evidence from Geula Cave, Israel

Journal of Quaternary Science, EarlyView.
ABSTRACT While competition with large carnivores is likely to have shaped Middle Paleolithic hominins' subsistence behavior, palimpsested human and carnivore accumulations render the signal challenging to isolate. This study presents a detailed zooarchaeological and taphonomic analysis of a non‐anthropogenic faunal assemblage from a MIS 5 (~130–80 ka ...

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Failure in Motion: A Framework for Capability Erosion and Institutional Dysfunction

Strategic Change, EarlyView.
ABSTRACT Drawing on the literature on capability erosion and institutional dysfunction (ID), this study develops a conceptual framework that sheds new light on how the interaction between capability erosion and ID creates conditions for business failure across borders. By articulating two dimensions of heterogeneous capability and resource erosion (i.e.

Size Matters: Barrier Heights and Widths in the Kinetics Of Tautomerisation and Rotamerisation of Thiotropolone and Its Five‐ and Three‐Membered Cyclic Analogues

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...
