Visual information is extremely important to generate internal spatial representations. In the auditory modality, the absence of visual cues during early infancy does not preclude the development of some spatial strategies. However, specific spatial abilities might result impaired. In the current study, we investigated the effect of early visual deprivation on the ability to localize static and...

Fixed effects estimates of structural parameters in nonlinear panel models can be severely biased due to the incidental parameters problem. In this paper I show that the most important component of this incidental parameters bias for probit fixed effects estimators of index coefficients is proportional to the true parameter value, using a large-T expansion of the bias. This result allows me to ...

This study examined the effect of stimulus movement on localization probability and latency during attention and inattention. Forty infants, 10 each at 8, 14, 20, and 26 weeks of age were presented with a central stimulus. Then, a peripheral stimulus was presented (static or dynamic checkerboard). Stimulus movement did not affect localization probability. Infants localized the dynamic periphera...

Exchange bias effect obtained after zero-field cooling from unmagnetized state usually exhibits a shift of hysteresis loop negative to the direction of the initial magnetic field, known as negative zero-field cooled exchange bias. Here, positive zero-field cooled exchange bias is reported in La0.5Sr0.5Mn0.8Co0.2O3 ceramics. In addition, a transition from positive to negative exchange bias has b...

Negative bias temperature instability (NBTI) and positive bias temperature instability (PBTI) are critical circuit reliability issues in highly scaled CMOS technologies. In this paper, we analyze the impacts of NBTI and PBTI on SRAM VMIN, and present a design solution for mitigating the impact of NBTI and PBTI on SRAM VMIN. Two different types of SRAM VMIN (SNM-limited VMIN and time-limited VMI...

We describe our present understanding of the relation between the behaviour near space-like infinity of asymptotically flat Cauchy data for Einstein’s vacuum field equations and the asymptotic behaviour of their time evolution at null infinity. It is shown that asymptotically flat, static vacuum solutions admit an analytic conformal representation in a neighbourhood of the critical sets at whic...
