NIR-MFCO dataset: Near-infrared-based false-color images of post-consumer plastics at different material flow compositions and material flow presentations

open access: yesData in Brief, 2023
Determining mass-based material flow compositions (MFCOs) is crucial for assessing and optimizing the recycling of post-consumer plastics. Currently, MFCOs in plastic recycling are primarily determined through manual sorting analysis, but the use of ...

Alkalinity responses to climate warming destabilise the Earth’s thermostat

open access: yesNature Communications, 2023
The weathering alkalinity flux from mid-latitudes to the ocean will be strongly altered by climate warming by 2100. Under different emissions scenarios either a strengthening or a weakening of the flux and thus of the oceanic CO2 buffer is predicted.

A multi-site study of the relationship between photoperiod and ovulation rate using Natural Cycles data

open access: yesScientific Reports, 2023
Many species exhibit seasonal patterns of breeding. Although humans can shield themselves from many season-related stressors, they appear to exhibit seasonal patterns of investment in reproductive function nonetheless, with levels of sex steroid hormones

Coordination cycles [PDF]

open access: yes, 2008
Players repeatedly face a coordination problem in a dynamic global game. By choosing a risky action (invest) instead of waiting, players risk instantaneous losses as well as a loss of payoffs from future stages, in which they cannot participate if they ...

LIFE CYCLE OF PRODUCTS AND CYCLES [PDF]

open access: yesMacroeconomic Dynamics, 2010
The aim of this paper is to examine whether the development of waste recycling activities can be a source of economic fluctuations. We assume that the recycling sector has four fundamental characteristics. (i) The production factors are restricted by the production of the last period.

Cycling behaviour in 17 countries across 6 continents: levels of cycling, who cycles, for what purpose, and how far?

open access: yesTransport reviews, 2021
International comparisons of cycling behaviour have typically been limited to high-income countries and often limited to the prevalence of cycling, with lack of discussions on demographic and trip characteristics. We used a combination of city, regional,

Shocks and Frictions in Us Business Cycles: A Bayesian DSGE Approach

open access: yesSocial Science Research Network, 2007
Using a Bayesian likelihood approach, we estimate a dynamic stochastic general equilibrium model for the US economy using seven macro-economic time series.

Analysis of Control-System Strategy and Design of a Small Modular Reactor with Different Working Fluids for Electricity and Hydrogen Production as Part of a Decentralised Mini Grid

open access: yesEnergies, 2022
Hydrogen is increasingly being viewed as a significant fuel for future industrial processes as it offers pathways to zero emission. The UK sees hydrogen as one of a handful of low-carbon solutions for transition to net zero.

Koszul cycles [PDF]

open access: yes, 2010
We prove regularity bounds for Koszul cycles holding for every ideal of dimension at most 1 in a polynomial ring. We generalize the lower bound for the Green-Lazarsfeld index of Veronese rings we proved in arXiv:0902.2431 to the multihomogeneous ...

SOLAR CYCLE 25: ANOTHER MODERATE CYCLE? [PDF]

open access: yesThe Astrophysical Journal Letters, 2016
ABSTRACT Surface flux transport simulations for the descending phase of Cycle 24 using random sources (emerging bipolar magnetic regions) with empirically determined scatter of their properties provide a prediction of the axial dipole moment during the upcoming activity minimum together with a realistic uncertainty range. The expectation
