The tunicates, or urochordates, constitute a large group of marine animals whose recent
common ancestry with vertebrates is reflected in the tadpole-like larvae of most tunicates. Their …

The first chordates appear in the fossil record at the time of the Cambrian explosion, nearly
550 million years ago. The modern ascidian tadpole represents a plausible approximation to …

We present a new class of long-period fiber gratings that can be used as in-fiber, low-loss,
band-rejection filters. Photoinduced periodic structures written in the core of standard …

The last two decades of research in cognitive aging have seen a shift from simply describing
age-related changes in cognitive performance to determining the mechanisms underlying …

Ascidians were historically the first metazoans in which experimental embryology was carried
out. These early works by Chabry and Conklin [Chabry, L., 1887. Embryologie normale et …

Although the proteins that read the gene regulatory code, transcription factors (TFs), have
been largely identified, it is not well known which sequences TFs can recognize. We have …

The instrument SUMER - Solar Ultraviolet Measurements of Emitted Radiation is designed
to investigate structures and associated dynamical processes occurring in the solar …

High pressure 'hydrogen loading' has been used to sensitise standard singlemode fibres,
resulting in the largest reported UV induced index changes for low GeO/sub 2/ fibres. Grating …

This study reports a longitudinal investigation of French 2nd graders' acquisition of single-digit
multiplication skill. Speed, accuracy, and strategy use were assessed 3 times within the …

We report measurements of thermally induced decay of fiber Bragg gratings patterned by
ultraviolet irradiation in germanium‐doped silica fiber. The decay is well characterized by a ‘‘…
