Long cycles, heavy cycles and cycle decompositions in digraphs [PDF]
Journal of Combinatorial Theory, Series B, 2021 Hajós 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 Bollobás and Scott (1996) it was analogously ...

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.

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.

Clustering Cycles into Cycles of Clusters [PDF]
Journal of Graph Algorithms and Applications, 2005 Summary: We study simple families of clustered graphs that are highly unconnected. We start by studying 3-cluster cycles, which are clustered graphs such that the underlying graph is a simple cycle and there are three clusters all at the same level. We show that in this case, testing the c-planarity can be done efficiently and give an efficient drawing

The Relationship Between Nutritional Status and Menarche Cycle in Students [PDF]
, 2023 Menstruation is periodic bleeding from the uterus that begins about 14 days after ovulation periodically due to the shedding of the lining of the uterus.

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

, 2023 Cycle, 2023, consists of 28 midfire cups in a gradient of colour from white to pink. Cycle references the loss of a personal cycle (from the removal of a uterus) but a reconnection to a universal cycle—celebrating/mourning the felt changes in the artist’

The Business Cycle and the Life Cycle [PDF]
NBER Macroeconomics Annual, 2004 The paper documents how cyclical fluctuations in market work vary over the life cycle and then assesses the predictions of a life-cycle version of the growth model for those observations. The analysis yields a simple but striking finding. The main discrepancy between the model and that data lies in the inability of the model to account for fluctuations

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 ...

The Electronic Journal of Combinatorics, 2022 Noting that cycle diagrams of permutations visually resemble grid diagrams used to depict knots and links in topology, we consider the knot (or link) obtained from the cycle diagram of a permutation. We show that the permutations which correspond in this way to an unknot are enumerated by the Schröder numbers, and also enumerate the permutations ...
