Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Absolute instability in axisymmetric wakes: Compressible and density variation effects
, 2008 International audienceLesshafft & Huerre (Phys. Fluids, 2007; vol. 19, 024102) have recently studied the transition from convective to absolute instability in hot round jets, for which absolute instability is led by axisymmetric perturbations and ...

Sliding Mode Control in Aerospace Applications: A Survey
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Sustainable Development, EarlyView.ABSTRACT In 2023, The Guardian reported on several scientific studies denouncing the role of certain forest carbon credits in mitigating climate change. Subsequently, credit prices on the voluntary carbon market (VCM) plummeted—providing a quantitative indication of its impact.

“Touching the Tarmac”: Conjuring the Urban Frontier on a Remote Periphery
Economic Anthropology, EarlyView.ABSTRACT Anthropologists have demonstrated how the creation of land markets as “frontiers” for global capital requires practices of “conjuring”—the narrative construction of place as desirable for large‐scale investment. This article emphasizes the contingency of this conjuring process in an urbanizing Kenya where land‐selling companies have emerged to

Integrating multimodal data and machine learning for entrepreneurship research
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

Integral Solution for the Mean Flow Profiles of Turbulent Jets, Plumes, and Wakes
, 2003 Integral methods are used to derive similarity solutions for several quantities of interest including the cross-stream velocity, Reynolds stress, the dominant turbulent kinetic energy production term, and eddy diffusivities of momentum and heat for ...

Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Research suggests that ventures benefit from framing to gain audience support, yet how they utilize framing when exogenous shocks redirect attention remains unclear. Drawing on a longitudinal multiple‐case study of six biotechnology ventures following the COVID‐19 pandemic, we show how ventures balance coherence and resonance ...

White light emitting molecular logic gates
Smart Molecules, EarlyView.White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.
