Agribusiness, EarlyView.ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

Projective space of a C*-module [PDF]
arXiv, 1999 Let X be a right Hilbert C*-module over A. We study the geometry and the topology of the projective space P(X) of X, consisting of the orthocomplemented submodules of X which are generated by a single element. We also study the geometry of the p-sphere S_p(X) and the natural fibration S_p(X) \to P(X), where S_p(X)={x\in X:

Neoliberalism in Argentina and Chile: common antecedents, divergent paths
, 2015 This paper contrasts the experiences of neoliberalism in Argentina and Chile, exploring why two countries that implemented apparently similar market reforms came to different stances on marketization: a post-neoliberal politics in Argentina, and a ...

Assessing Agricultural Green Total Factor Productivity in Latin America
Agribusiness, EarlyView.ABSTRACT The agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel ...

Substrate size modifies stream grazer–biofilm interactions in the presence of invertivorous fish
Ecology, Volume 103, Issue 12, December 2022., 2022 Abstract When herbivore abundance is controlled by predators there may be an indirect positive effect on primary producers due to reduced grazing pressure, but the potential of predation refuges to modify such trophic cascades has rarely been studied.

Economic Feasibility of Crop‐Livestock Integration System in Brazil
Agribusiness, EarlyView.ABSTRACT We investigate the economic feasibility of the Brazilian crop‐livestock integration system. Under this system, the Brazilian farmer can produce soybeans, corn, and graze for cattle on the same land during one crop year. This technology can substantially increase agricultural production in the country.

Uncontrolled Learning: Codesign of Neuromorphic Hardware Topology for Neuromorphic Algorithms
Advanced Intelligent Systems, EarlyView.Codesign is used to implement a neuroscience‐inspired machine learning algorithm in all neuromorphic hardware. In this implementation, the hidden memristors cannot be directly accessed, limiting control of the network during training. By leveraging theoretical tools, including memristor circuits dynamics and a closed form expression for the network ...

Las antenas de espacio profundo en la Argentina [PDF]
arXiv, 2018 Since December 2012, the Deep Space Antenna DS3 of the European Space Agency was inaugurated in the province of Mendoza. The possibility of using this equipment for space and scientific activities was promoted by our country. Several scientific institutions in the country are working together so that part of the observation time assigned to Argentina ...
