The visual system of a fly expresses several circadian rhythms that have been detected in the photoreceptors of the compound eye and in the first neuropile, the lamina, of the underlying optic lobe. In the lamina, axons of two classes of interneuron, L1 and L2, exhibit cyclical size changes, swelling by day and shrinking by night. These rhythmic size changes may be generated by circadian oscill...

This papers studies how the stabilization role of monetary policy in response to asset price shocks changes with the globalization of financial markets. Changes in asset prices affect production through a credit channel and monetary policy can stabilize the macro-economy with counter-cyclical interventions. The paper shows that, as financial markets become internationally integrated, stabilizat...

Cyclical fluctuations of cerebral blood flow velocity have been reported previously using Doppler ultrasound. The same phenomena was detected during investigations of changes in cerebral blood volume using near infrared spectroscopy. Rhythmic fluctuations of cerebral blood volume at a frequency of 3.5 cycles/minute is reported here.

A child with cyclical neutropenia was observed before and during treatment with levamisole. Marked clinical improvement occurred while on levamisole. Deterioration occurred after stopping treatment. The improvement was not associated with changes in the neutrophil or monocyte counts, nor did tests of phagocytic cell function convincingly demonstrate improvement while the child was on treatment.

Changes in the price of nontradable goods relative to tradable goods account for roughly 50 percent of the cyclical movements in real exchange rates. J.E.L. Classification: F31 ∗UCLA. †Northwestern University, NBER, and Federal Reserve of Chicago. ‡Northwestern University, NBER, and CEPR.

In this paper, we study how cytoskeletal remodeling is correlated to changes in subcellular microrheology. We analyze the changes in the magnitude and directionality of the shear and elastic moduli of bovine aortic endothelial cells (BAECs) exposed to cyclical, uniaxial stretch. We find that, when stretched, BAECs stiffen and align their softest direction of mechanical polarization perpendicula...

This paper investigates the effect of changes in the retention ratio, profit share, interest rate, and natural rate of growth on the rate of capital accumulation and the financial structure of firms by using a Kaleckian growth model with labor supply constraints. We show that if the economy exhibits a debt-burdened regime, depending on certain conditions, there could be cyclical fluctuations su...

In our study the VCC technique has been used to observe changes in the arrangement of the blood vessels in the wall of the gallbladder and urinary bladder in pig, which undergoes a variable change in the volume during their cyclical filling of urine or bile. The changes in the angioarchitecture of the gallbladder and urinary bladder has been describe in a few species of laboratory animals, but ...

Cyclical mastalgia is a common complaint, with a potentially important relationship to breast cancer risk. In the last decade, case-control studies have reported that cyclical mastalgia could be considered as an independent risk factor for breast cancer. The subjectivity of a retrospectively collected symptom questioned the validity of this finding. We have examined the association between cycl...

The paper addresses the issue of the driving forces behind recent changes in labour market entry outcomes in Europe. Based on data for 12 European countries from the 1988-1997 European Community Labour Force Survey, the empirical analyses estimate panel data models to assess the effects of cyclical changes in aggregate economic conditions, changing youth cohort sizes, increasing educational exp...
