The interdependence of the development of the eye and oculomotor system during embryogenesis is currently unclear. The occurrence of clinical anophthalmia, where the globe fails to develop, permits us to study the effects this has on the development of the complex neuromuscular system controlling eye movements. In this study, we use very high-resolution T2-weighted imaging in five anophthalmic ...

To the Editor : Heterozygous, loss of function mutations in the high mobility group (HMG) gene, SOX2 , encoding the sex-determining region Y-box 2 (MIM 184429) protein, lead to severe developmental eye and brain malformations, and some anophthalmos-esophagealgenital syndrome cases (1). However, the fate of these cases into adulthood is unknown. We report an adult with SOX2 anophthalmia syndrome...

The effect of local PMD and PDL directional correlation is considered for the first time in a single mode fiber communication link. It is shown that the autocorrelation between the real and imaginary part of the complex principal state vector is nonzero in general. Experimental results verifying the local correlation between PMD and PDL directional are reported.

Materials and methods Three commercial PMDs were first assessed and then compared during barefoot walking: PMDa and PMDb resistive technology, 1sens/cm – were assessed onsite, while PMDc – capacitive technology, 4sens/cm was tested on-the-bench and on-site [1]. The PMDs were aligned on the floor to capture successive at-regimen steps of the left foot of one trained volunteer; 10 complete steps ...

We present two PMD compensation schemes suitable for use in multilevel (M>or=2) block-coded modulation schemes with coherent detection. The first scheme is based on a BLAST-type polarization-interference cancellation scheme, and the second scheme is based on iterative polarization cancellation. Both schemes use the LDPC codes as channel codes. The proposed PMD compensations schemes are evaluate...

We propose and demonstrate a polarization-time coding (PTC) method which can effectively compensate both the CD and first order PMD in direct-detected OFDM transmission. Compared with the previous methods, the proposed PTC not only alleviates the need for the complex dynamic polarization controller but also exhibits superior transparencies to both the OFDM format and transmission data rate. For...
