Long cycles, heavy cycles and cycle decompositions in digraphs [PDF]
Journal of Combinatorial Theory, Series B, 2021 Haj s conjectured in 1968 that every Eulerian \(n\)-vertex graph can be decomposed into at most $\lfloor (n-1)/2\rfloor$ edge-disjoint cycles. This has been confirmed for some special graph classes, but the general case remains open. In a sequence of papers by Bienia and Meyniel (1986), Dean (1986), and Bollob s and Scott (1996) it was analogously ...

International Economic Review, 2010 Operating overheads are widespread and lead to concentrated bursts of activity. To transfer resources between active and idle spells, agents demand financial assets. Futures contracts and lotteries are unsuitable, as they have substantial overheads of their own.

Monetary Cycles, Financial Cycles and the Business Cycle [PDF]
SSRN Electronic Journal, 2010 One of the most robust stylized facts in macroeconomics is the forecasting power of the term spread for future real activity. The economic rationale for this forecasting power usually appeals to expectations of future interest rates, which affect the slope of the term structure.

LIFE CYCLE OF PRODUCTS AND CYCLES [PDF]
Macroeconomic 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.

SOLAR CYCLE 25: ANOTHER MODERATE CYCLE? [PDF]
The 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

COVID-19 Impacts on Cycling, 2019–2020
, 2021 The COVID-19 pandemic has had an enormous impact on travel behaviour in most of the world. This editorial examines the available evidence about the impact of the pandemic on cycling in various citi...

Nitrate addition inhibited methanogenesis in paddy soils under long-term managements
Plant, Soil and Environment, 2018 Rice fields are a major source of atmospheric methane (CH4). Nitrate has been approved to inhibit CH4 production from paddy soils, while fertilization as well as water management can also affect the methanogenesis.

Harrogate consensus agreement: Cycling-specific sport-related concussion
Sports Medicine and Health Science, 2021 Sport-related concussion (SRC) is a common and increasingly recognised sport-related injury and accounts for between 1% and 9% of all cycling-specific injuries.

Transport 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,

Individual, social and physical environmental correlates of 'never' and 'always' cycling to school among 10 to 12 year old children living within a 3.0 km distance from school [PDF]
, 2012 BACKGROUND: Cycling to school has been identified as an important target for increasing physical activity levels in children. However, knowledge about correlates of cycling to school is scarce as many studies did not make a distinction between walking ...
