Abstract While flexible exchange rates are commonly regarded as shock absorbers, heterodox views suggest that they can play a pro-cyclical role in emerging markets. This article provides theoretical and empirical support for this view. Drawing on post-Keynesian structuralist theories, we propose simple model which conjunction with external shocks become endogenous drivers of boom-bust cycles, o...

We present results from Keck HIRES, KPNO 4m/RC Spec and HST FOS spectra of a low-redshift, close QSO pair and a close, higher-redshift QSO triplet in order to explore the size evolution, shape and clustering of Ly α absorbers. The results we highlight here indicate that there is no strong evidence for evolution of Ly α cloud size with redshift, that strong (Wo > 0.4Å) Ly α forest absorbers are ...

We present spectroscopic observations of the damped Lyα absorber at redshift z = 1.9342 seen in the spectrum of the quasar Q0151+048A. The redshift of the absorber is greater than the redshift of the quasar, so the system resembles the zabs ≈ zem damped absorber at z = 2.81 towards the quasar PKS0528-250. We have previously reported the detection of Lyα emission from the latter absorber, one of...

This article proposes a simple physical-based model to describe and predict the performance of axially compressed magnetorheological elastomer cylinders used as vibration shock absorbers. The describes macroscopic stiffness changes because an externally applied magnetic field from microscopic composite cell silicone rubber carbonyl iron particle. Despite neglecting material hyperelasticity, ani...

OBJECTIVE Although it is known that the papillary muscles ensure the continuity between the left ventricle (LV) and the mitral apparatus, their precise mechanism needs further study. We hypothesize that the papillary muscles function as shock absorbers to maintain a constant distance between their tips and the mitral annulus during the entire cardiac cycle. MATERIALS AND METHODS Sonomicrometr...

We compare three different approaches to high-resolution contact lithography with special emphasis on contrast mechanisms for subwavelength structures. Masks with protruding metal absorbers, masks with absorbers embedded in the transparent background, and masks with air gaps and recessed absorbers are studied. Using the Green’s tensor technique we compute the light intensity distribution in the...
