Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

open access: yesAngewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

Results and observations from the reconstruction of continuous time series of mortality by cause of death: Case of West Germany, 1968-1997.

open access: yesDemographic Research, 2009
Though many countries have been collecting cause-of-death information from death certificates for more than a century, these valuable data sources remain underexplored.

The role of venture‐financed startups in innovation for US agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Soft Interactions, Rather Than Crowder Size, Determine Deviations From Arrhenius‐Like Kinetics of Phosphofructokinase‐1

open access: yesAngewandte Chemie, EarlyView.
Our study investigates macromolecular crowding effects in the Arrhenius‐like and non‐Arrhenius temperature regimes of the human platelet isoform of phosphofructokinase‐1 (PFKP). The results reveal how PFKP maintains temperature robustness of catalytic activity in differently crowded environments.

Diagnosing the system: Mental health, necropolitical uncare, and the abolition of migration detention

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This article examines the psychological effects of migration detention in the European Union's Closed Controlled Access Center (CCAC) on Samos through an ecological lens. It explores a double normalization of suffering: the brutalization of necropolitical migration governance and the simultaneous understanding of resulting distress as an ...

Splenic Tropism and Spleen‐Modulated Systemic Inflammation in Acute Plasmodium vivax Malaria

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT In chronic Plasmodium vivax (Pv) infection, the spleen accounts for over 98% of total‐body parasite biomass. Whether splenic tropism also occurs in acute infection and how the spleen influences pathogenesis have not been systematically explored. In Papua, Indonesia, we compared clinical and hematology data in 24 spleen‐intact and 25 previously

The International Consortium for Arthrogryposis: A Collaborative Framework for Early Detection, Care, Research, and Education

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis multiplex congenita (AMC) is a group of rare congenital conditions, characterized by multiple joint contractures but may involve any body system including central nervous system. AMC is etiologically heterogeneous, with over 400 genetic and many non‐genetic causes implicated in its prenatal development.
