Microbunching Instability in Velocity Bunching [PDF]
, 2009 Microbunching instability is one of the most challenging threats to FEL performances. The most effective ways to cure the microbunching instability include suppression of the density modulation sources and suppression of the amplification process.

River Research and Applications, EarlyView.ABSTRACT In France, it is estimated that shads (Alosa spp.) have lost 69% of their historical range, mainly due to disrupted river connectivity. After an absence of one century, signs of their return in the Seine River have been recorded over the past two decades: adult and juvenile specimens have been caught by anglers or recorded at video‐counting ...

Frequency-diverse bunching metasurface antenna for microwave coincidence imaging
A frequency-diverse bunching metasurface antenna (FDBMA) that can be used for microwave coincidence imaging (MCI) is proposed in this paper. The proposed FDBMA consists of two distinct types of apertures: the bunching aperture and the random aperture.

Contract Farming and Children's Education: Evidence From Maize Producers in Ghana
Sustainable Development, EarlyView.ABSTRACT The institution of contract farming (CF) has continued to proliferate in the small farm sector of developing countries. While its effects on smallholders across welfare outcomes such as income and food security have been well documented, there are growing concerns about its broader social implications especially on children.

Unnatural Causes: Cryptocurrencies, Carbon Credits, and the rise of Neoliberalism from Below
Economic Anthropology, EarlyView.ABSTRACT Klima is a carbon‐backed cryptocurrency running as a decentralized autonomous organization (DAO). In 2021, it had accumulated 9 million metric tons of digital carbon credits and reached a market value of more than US$1 billion. In 2023, its treasury stored twice as many carbon credits, but its spot price was a tiny fraction compared to 2021 ...

A data-driven procedure to determine the bunching window [PDF]
, 2016 This paper presents new empirical evidence on taxpayers responsiveness to taxation by estimating the compensated elasticity of taxable income with respect to the net-of-tax rate in the Netherlands. Applying the bunching approach introduced by Saez (2010),

Strategic framing of novel ideas: How contestation shapes the evolution of novelty
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Entrepreneurs use strategic framing to gain support for their novel ventures, products, and services. A key challenge entrepreneurs face is that audiences often contest frames that introduce novel ideas, especially when these ideas disrupt audiences' mental and business models.

Surface and Interface Analysis, EarlyView.ABSTRACT Accurate alignment of histopathological structures in optical images and imaging mass spectrometry (IMS) datasets is crucial for providing meaningful biological interpretation. Integrating IMS with optical or other imaging modalities remains challenging due to sample‐preparation constraints, mismatched spatial resolutions, and the need for ...

Strategic Management Journal, EarlyView.Abstract Research Summary Despite growing interest in platform transitions, limited research examines how firms navigate challenges of building platform businesses alongside existing products. Through a longitudinal case study of a financial services firm launching a platform, we develop a process model revealing how data bottlenecks shape platform ...
