This paper analyses two well-known features of interest rates, namely their time dependence and their cyclical structure. Specifically, it focuses on the monthly Euribor rate, using monthly data from January 1994 to May 2011. Models based on fractional integration at the long run or zero frequency, although adequately describing the persistent behaviour of the series, do not take into account i...

This article documents the business cycle properties of workers’ remittance flows to Mexico. We also discuss key differences between the cyclical properties of remittance inflows and the cyclical properties of foreign direct investment (FDI). We find evidence that remittances are countercyclical with respect to Mexico’s business cycle. However, this result is not robust to the use of different ...

Mammalian spermatogenesis contributes a constant production of large numbers of spermatozoa, which is achieved by a cyclically regulated program known as the seminiferous epithelial cycle. Sertoli cells, functionally unique somatic cells, create a microenvironment to support the continuous differentiation of germ cells especially through the formation of a blood-testis barrier (BTB). The BTB is...

Large changes in government revenues can have disruptive effects on the action of states and increase uncertainty in the economy. In the interwar period, and during the Great Depression years in particular, many countries experienced such events. This paper investigates how the composition of taxes and countries’ fiscal capacity interacted with economic conditions to determine the evolution of ...

The Austrian business cycle theory suggests that a monetary shock disturbs relative prices, such as the term structure of interest rates, systematically altering profit rates across economic sectors. Resource use responds to those changes, generating a cyclical pattern of real income. The divergence of the interest rate structure, from the previous and unchanged time preferences, means that the...

Efficient muscle-tendon performance during cyclical tasks is dependent on both active and passive mechanical tissue properties. Here we examine whether age-related changes in the properties of muscle-tendon units (MTUs) compromise their ability to do work and utilize elastic energy storage. We empirically quantified passive and active properties of the medial gastrocnemius muscle and material p...

A simple histochemical procedure for assessing relative amounts of neutral and acidic sugars in mucin glycoproteins, and its application in the study of cyclical changes ofhuman cervical mucins, is described. This procedure, the saponification/selective periodate oxidation/borohydride reduction/alcian blue pH 2-5/periodic acid Schiff (KOH/PA*/Bh/Ab 2-5/PAS) method, uses a selective oxidation st...

A simple histochemical procedure for assessing relative amounts of neutral and acidic sugars in mucin glycoproteins, and its application in the study of cyclical changes of human cervical mucins, is described. This procedure, the saponification/selective periodate oxidation/borohydride reduction/alcian blue pH 2.5/periodic acid Schiff (KOH/PA*/Bh/Ab 2.5/PAS) method, uses a selective oxidation s...

Ag receptor diversity involves the introduction of DNA double-stranded breaks during lymphocyte development. To ensure fidelity, cleavage is confined to the G(0)-G(1) phase of the cell cycle. One established mechanism of regulation is through periodic degradation of the RAG2 recombinase protein. However, there are additional levels of protection. In this paper, we show that cyclical changes in ...
