Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

British Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

Non‐Buckling Stacks of Nanocarbon Molecules

Angewandte Chemie, EarlyView.
A nanometer‐sized nanocarbon molecule with a central octagon was synthesized by optimizing a tetrameric macrocyclization via concentration‐dependent yield analysis (CYAN). The slightly contorted molecular structure was found to be frozen in a dimeric stack in solution, whereas dissociation into monomers liberated the molecule to undergo buckling ...

Are dairy cows replaced too early? Evidence from a structural model and cow‐level data

American Journal of Agricultural Economics, EarlyView.
Abstract In past analyses of animal replacement decisions, studies have claimed that dairy farms often replace dairy cows too early to be maximizing profits. I estimate a structural model of asset replacement to determine the motives behind early replacement of dairy cows.

Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate

Angewandte Chemie, EarlyView.
Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

Ransomware Obfuscation Techniques

, 2019
This master's thesis seeks to design, implement, and point out new techniques for obfuscation of ransomware activity using the entropy principles of data that do not fall within the detection capabilities of known anti-ransomware and anti-virus tools ...

A well‐resolved phylogeny of Cuscuta subgenus Monogynella based on data drawn from all three plant genomes

American Journal of Botany, EarlyView.
Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

Obfuscation from Polynomial Hardness: Beyond Decomposable Obfuscation [PDF]

, 2019
Every known construction of general indistinguishability obfuscation ($\mathsf{i}\mathcal{O}$) is either based on a family of exponentially many assumptions, or is based on a single assumption -- e.g.~functional encryption ($\mathsf{FE}$) -- using a ...
