The Role of Coordination Mechanisms and Transaction Costs Promoting Sustainability Performance in Agri‐Food Supply Chains: Evidence From Ecuador

open access: yesAgribusiness, 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.

Tropical bounds for eigenvalues of matrices

open access: yes, 2013
We show that for all k = 1,...,n the absolute value of the product of the k largest eigenvalues of an n-by-n matrix A is bounded from above by the product of the k largest tropical eigenvalues of the matrix |A| (entrywise absolute value), up to a ...

A Standardized Framework for Elastomer Characterization in Soft Robotics

open access: yesAdvanced Intelligent Systems, EarlyView.
A unified framework addresses inconsistent elastomer property reporting which limits reproducibility and standardization in soft robotics. Systematic testing of ten elastomers (thermosetting, thermoplastic, and a covalent adaptable network) provides quasielastic mechanical properties, viscoelastic parameters, thermal stability, and processing ...

Disentangling Coincident Cell Events Using Deep Transfer Learning and Compressive Sensing

open access: yesAdvanced Intelligent Systems, EarlyView.
Overlapping cells during detection distort single‐cell measurements and reduce diagnostic accuracy. A hybrid framework combining a fully convolutional neural network with compressive sensing to disentangle overlapping signals directly from raw time‐series data is presented.

Brunn-Minkowski Inequalities for Contingency Tables and Integer Flows

open access: yes, 2006
Given a non-negative mxn matrix W=(w_ij) and positive integer vectors R=(r_1, >..., r_m) and C=(c_1, ..., c_n), we consider the total weight T(R, C; W) of mxn non-negative integer matrices (contingency tables) D with the row sums r_i, the column sums c_j,

Psychoactive prescription drug use and misuse in patients on opioid agonist treatment

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims To identify the patterns and trends in prescription drug use and misuse in patients on opioid agonist treatment. Methods We used data from the OPPIDUM programme, which collects data from patients attending substance abuse treatment facilities. Data collected include use of psychoactive prescription drugs in the past week.
