1. Effects of conventional, organic and conservation agriculture on soil physical properties, root growth and microbial habitats in a long-term field experiment 

   Oliveira, Emily M.; Wittwer, Raphaël; Hartmann, Martin; et al. (2024)

   Geoderma

   Soil structure is important for plant growth and ecosystem functioning, and provides habitat for a wide range of soil biota. So far, very few studies directly compared the effects of three main farming practices (conventional, organic and conservation agriculture) on soil structure and soil physical properties. Here, we collected undisturbed soil cores from the FArming System and Tillage long-term field experiment (FAST) near Zurich ...

2. Measuring Arbitrage Losses and Profitability of AMM Liquidity 

   Fritsch R.; Canidio A. (2024)

   WWW 2024 Companion - Companion Proceedings of the ACM Web Conference

   This paper presents the results of a comprehensive empirical study of losses to arbitrageurs (following the formalization of loss-versus-rebalancing by [Milionis et al., 2022]) incurred by liquidity on automated market makers (AMMs). Through a systematic comparison between historical earnings from trading fees and losses to arbitrageurs, our findings indicate an insufficient compensation from fees for arbitrage losses across many of the ...

3. MS MARCO Web Search: a Large-scale Information-rich Web Dataset with Millions of Real Click Labels 

   Chen Q.; Geng X.; Rosset C.; et al. (2024)

   WWW 2024 Companion - Companion Proceedings of the ACM Web Conference

   Recent breakthroughs in large models have highlighted the critical significance of data scale, labels and modals. In this paper, we introduce MS MARCO Web Search, the first large-scale information-rich web dataset, featuring millions of real clicked query-document labels. This dataset closely mimics real-world web document and query distribution, provides rich information for various kinds of downstream tasks and encourages research in ...

4. Shock! Quantifying the Impact of Core Developers’ Dropout on the Productivity of OSS Projects 

   Latona G.R.; Gote C.; Zingg C.; et al. (2024)

   WWW 2024 Companion - Companion Proceedings of the ACM Web Conference

   Open Source Software (OSS) projects play a critical role in the digital infrastructure of companies and services provided to millions of people. Given their importance, understanding the resilience of OSS projects is paramount. A primary reason for OSS project failure is the shock caused by the dropout of a core developer, which can jeopardize productivity and project survival. Using a difference-in-differences (DiD) analysis, this study ...
