A plantigrade foot with a large robust calcaneus is regarded as a distinctive morphological
feature of the human foot; it is presumably the result of adaptation for habitual bipedal …

High-speed and high-density interconnections between racks and modules in the high-performance
computing systems and data centers are currently being developed. The …

This study extends two ideas of the minimalist program in linguistic theory (Chomsky 1992,
1994, 1995a)(LF feature decomposition and elimination of D-structure), and explores various …

We developed a 25-Gb/s VCSEL transmitter with 10-Gb/s VCSEL. By driving standard 10-
Gb/s VCSELs using pre-emphasis technology to overcome their optical bandwidth limit, we …

Photoluminescence properties are studied on yttria-stabilized zirconia (YSZ) samples aged
up to 1000 h at the temperature of 1073 K where the aging-induced decrease in conductivity …

A high-density multi-rate VCSEL transceiver with CDRs was developed. We succeed in
suppressing the jitter of optical link by developing CDR for the receiver, and realized a 24 to …

To meet increasing demands for server computational power, high-density, multilane links
with a data rate exceeding 25Gb/s/lane are needed. An optical transceiver with a retiming …

The 25.78-Gb/s VCSEL transceiver with retimer-embedded ICs was firstly developed. We
succeeded to suppress the power as low as 200 mW/lane for retime function and realized …

A compact card-edge optical transceiver with a cost-effective flexible printed circuit (FPC)
based module structure has been developed. Clear eye-openings operating at 200 Gb/s (8-…

We developed a 25-Gb/s transmitter with an over-drive of 10-Gb/s VCSEL using our
asymmetric pre-emphasis design. Owing to the narrow spectral width characteristics of our …
