Inner margins of fingers of second chelae dark purplish.</p> <p> <b>Distribution</b>. Known only from northeastern Taiwan; at depths of 326– 447 m.</p> <p> <b>Remarks</b>. The present new species agrees well with the diagnosis of <i>Calastacus</i>, provided by de Saint Laurent (1972), Kensley (1989), Poore (1994) and Poore & Collins (2009). The genus is currently represented by seven species worldwide, <i>C. stilirostris</i> Faxon, 1893 (type species) from the eastern Pacific off Mexico to Peru, <i>C. laevis</i> de Saint Laurent, 1972 from the eastern Atlantic and Mediterranean, <i>C. colpos</i> Kensley, 1996 from the northwestern Gulf of Mexico, <i>C. mexicanus</i> Kensley, 1996 from the Gulf of Mexico, <i>C. crosnieri</i> Kensley & Chan, 1998 from Taiwan, <i>C. inflatus</i> Komai, Lin & Chan, 2009 from the South China Sea off the Pratas Islands, and <i>C. myalup</i> Poore & Collins, 2009 from south Western Australia (Kensley 1996a; Kensley & Chan 1998; Ngoc-Ho 2003; Komai <i>et al.</i> 2009; Poore & Collins 2009). The new species appears closest to <i>C. myalup</i> in the presence of a pterygostomial spine on the carapace and the suture of the uropodal exopod, which bears 10 or more slender spiniform setae. Nevertheless, <i>C. formosus</i> n. sp. differs from <i>C. myalup</i> in the shape of the uropodal endopod. In <i>C. formosus</i>, the posterior margin of the uropodal endopod is subtruncate, but it is rounded in <i>C. myalup</i>. Furthermore, the supraorbital spine on the carapace only just exceeds the orbital margin of the carapace in <i>C. formosus</i> n. sp., rather than overreaching the middle of the eye in <i>C. myalup</i>. The ornamentation of the appendix masculina of the second pleopod consists only of stiff setae in <i>C. formosus</i>, but it includes spiniform setae in <i>C. myalup</i>.</p> <p> This is the second species of <i>Calastacus</i> known from Taiwan. The other species is <i>C. crosnieri</i>, which is golden yellow in color and very different from the pale yellowish body of <i>C. formosus</i>. Considering the general scarcity of species of the genus around the world, the presence of two species from the same region is rather remarkable.</p> <p> <b>Etymology</b>. The species is named after its type locality Taiwan derived from a former name, “ Formosa ”.</p>Published as part of <i>Lin, Tomoyuki Komai Feng-Jiau & Chan, Tin-Yam, 2010, Five new species of Axiidae (Crustacea: Decapoda: Axiidea) from deep-water off Taiwan, with description of a new genus, pp. 1-28 in Zootaxa 2352</i> on pages 13-18, DOI: <a href="http://zenodo.org/record/193489">10.5281/zenodo.193489</a>

The Relationship Between Pretend Play and Playfulness in Children With Autism Spectrum Disorder
No full textAbstract
Date Presented 3/30/2017
This study explored the relationship between pretend play and playfulness in children with autism spectrum disorder (ASD). Our findings suggest that it is important to assist children with ASD to engage in pretend play, for doing so could promote their internal experience of playfulness.

Study on Urban Context Reconstruction and Management of Island Countries - take operation of stereoscopic warehouse in Taichung as example
No full textThis study intends to explore the feasibility study of urban texture reconstruction and management. The purpose of this study is to understand the Taichung City government's research on the renovation and activation of the Taiwan Neutral Library, and make recommendations based on its research results. Government department heads have drawn reference for policies related to the preservation and activation of monuments and idle spaces. Based on the above research background, motivation and purpose, this study summarizes three research questions as the basis for the investigation and analysis of this research. The contents are as follows:
First, the preservation and repair of the government's historic sites are not in a hurry, and the performance is not up to the decline of the building.
Second, the competition between public construction and historic sites and urban textures. Conflict.
Third, the management of the preservation and reconstruction of the monuments is the best demonstration and propaganda of the cultural education and historical context of the monument itself.
Finally, the results of this research hope to bring to the government departments a clear and effective strategy for the preservation and activation of historic sites and idle spaces, which will help the government departments to preserve and revitalize the monuments in the historic sites, and then drive the localities. The development of geosciences and cultural tourism will help local governments promote urban tourism and enhance the visibility of the city. It is worth mentioning that the output of this research not only hopes to contribute academically, but also hopes that the results can be used as a government department to help the preservation and activation strategies of monuments and idle spaces

Compact, high-pulse-energy, high-power, picosecond master oscillator power amplifier
No full textWe report a compact, stable, gain-switched-diode-seeded master oscillator power amplifier (MOPA), employing direct amplification via conventional Yb3+-doped fibers, to generate picosecond pulses with energy of 17.7µJ and 97W average output power (excluding amplified spontaneous emission) at 5.47MHz repetition frequency in a diffraction-limited and single-polarization beam. A maximum peak power of 197kW is demonstrated. Such a high-energy, high-power, MHz, picosecond MOPA is of great interest for high-throughput material processing. With 13.8µJ pulse energy confined in the 0.87nm 3dB spectral bandwidth, this MOPA is also a promising source for nonlinear frequency conversion to generate high-energy pulses in other spectral regions. We have explored the pulse energy scaling until the stimulated Raman Scattering (SRS) becomes significant (i.e. spectral peak intensity exceeds 1% of that of the signal)
