Data 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 ...

Scientific 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

Alkalinity responses to climate warming destabilise the Earth’s thermostat
Nature 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.

The Business Cycle and the Life Cycle [PDF]
NBER Macroeconomics Annual, 2004 Our paper documents the differences in the variability of hours worked over the business cycle across several demographic groups and shows that these differences are large. We argue that understanding these differences should be useful in understanding the forces that account for aggregate fluctuations in hours worked.

The Cell Cycle is a Limit Cycle [PDF]
Mathematical Modelling of Natural Phenomena, 2012 Progression along the successive phases of the mammalian cell cycle is driven by a network of cyclin-dependent kinases (Cdks). This network is regulated by a variety of negative and positive feedback loops. We previously proposed a detailed, 39-variable model for the Cdk network and showed that it is capable of temporal self-organization in the form of

Enumeration of cyclic vertices and components over the congruence a¹¹ ≡ b (mod n) [PDF]
Notes on Number Theory and Discrete Mathematics, 2023 For each positive integer n, we assign a digraph Γ(n,11) whose set of vertices is Zₙ={0,1,2,...,n-1} and there exists exactly one directed edge from the vertex a to the vertex b iff a¹¹ ≡ b (mod n).

The Seasonal Cycle and the Business Cycle [PDF]
Journal of Political Economy, 1989 Almost all recent research on macroeconomic fluctuations has worked with seasonally-adjusted or annual data. This paper takes a different approach by examining the seasonal movements themselves. The authors' results show that seasonal fluctuations are an important source of variation in all macroeconomic quantity variables, but are small or absent in ...
