In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

Economic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Temporal Responses to Warming: Do Wild Herbivores Trade Off Heat, Predators, and Humans?

Integrative Zoology, EarlyView.
We untangled how summer temperature, predators, and humans influenced behavioral responses in two deer species. Both reduced their daily activity level in response to warming, yet only roe deer increased nocturnality to avoid heat. Conversely, fallow deer traded off heat avoidance with predator avoidance.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

How iteration frequencies affect project uncertainty and risk ‐ An empirically elaborated model

Decision Sciences, EarlyView.
Abstract Iterative approaches have gained prominence in new product development (NPD) projects in response to increasingly dynamic and turbulent business environments. In this article, we study how iteration frequency—that is, the rhythm at which development teams revisit and test comprehensive products—affects an NPD project's uncertainty and risk. We
