    Description: About half of the 8 cm/yr of oblique convergence across the active convergent plate boundaries of Taiwan occurs in eastern Taiwan, across the Longitudinal Valley. Significant shortening and left-lateral slip occurs across the Longitudinal Valley fault there, both as shallow fault creep and as seismogenic fault slip. The southernmost Longitudinal Valley fault comprises an eastern Peinan strand and a western Luyeh strand. We derive an interseismic block model for these two strands using data from a small-aperture Global Positioning System (GPS) campaign and leveling. The model provides estimates of fault slip rates and quantifies slip partitioning between the two strands. A 45 mm/yr dip-slip rate on the northern Peinan strand diminishes southward, whereas the left-lateral component increases. In contrast, nearly pure dip-slip motion of about 20 mm/yr on the southern Luyeh strand diminishes northward to about 8 mm/yr and picks up a component of left-lateral motion of about 15 mm/yr before it dies out altogether at its northern terminus. The Luyeh and the northern Peinan strands record near-surface creep, but the southern Peinan strand appears locked. The potential earthquake magnitude for the two strands may be as high as M w  6.5. We anticipate seismic rupture mainly on the locked portion of the Peinan strand.

    Description: The contemporary presence of the Puli Topographic Embayment within the Taiwanese thrust belt provides insight into processes that initiate and maintain a subcritical state in a thin-skinned compressive wedge. Orogen-scale analyses of Taiwan have succeeded in describing the processes and interactions that affect overall development of the thrust belt; however, relatively little is known about which processes or boundary conditions control first-order organization of strain at intermediate scales within the orogenic wedge. We investigate spatial and temporal scales of variation in the overall topographic and structural architecture of a critical wedge and explore the boundary conditions that affect very rapid shortening and erosion at intermediate scales on the order of 101 kilometers and 104–105 years. Causal links between the structural and synorogenic stratigraphic architecture of the foreland basin and coincidence of the Puli Topographic Embayment provide a valuable case study of the effects of changing boundary conditions (e.g., variable erodibility or strength of rocks along strike) controlling the evolution of critically tapered thin-skinned orogens. Deeper incision of river networks into a thicker sequence of unconsolidated synorogenic sediments in the central western foreland may affect the onset of a topographically subcritical state.

    Description: The Smad proteins mediate transforming growth factor-beta (TGFbeta) signaling from the transmembrane serine-threonine receptor kinases to the nucleus. The Smad anchor for receptor activation (SARA) recruits Smad2 to the TGFbeta receptors for phosphorylation. The crystal structure of a Smad2 MH2 domain in complex with the Smad-binding domain (SBD) of SARA has been determined at 2.2 angstrom resolution. SARA SBD, in an extended conformation comprising a rigid coil, an alpha helix, and a beta strand, interacts with the beta sheet and the three-helix bundle of Smad2. Recognition between the SARA rigid coil and the Smad2 beta sheet is essential for specificity, whereas interactions between the SARA beta strand and the Smad2 three-helix bundle contribute significantly to binding affinity. Comparison of the structures between Smad2 and a comediator Smad suggests a model for how receptor-regulated Smads are recognized by the type I receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, G -- Chen, Y G -- Ozdamar, B -- Gyuricza, C A -- Chong, P A -- Wrana, J L -- Massague, J -- Shi, Y -- CA85171/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2000 Jan 7;287(5450):92-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Princeton University, Lewis Thomas Laboratory, Princeton, NJ 08544, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10615055" target="_blank"〉PubMed〈/a〉

    Description: Nodal proteins, members of the transforming growth factor-beta (TGFbeta) superfamily, have been identified as key endogenous mesoderm inducers in vertebrates. Precise control of Nodal signaling is essential for normal development of embryos. Here, we report that zebrafish dapper2 (dpr2) is expressed in mesoderm precursors during early embryogenesis and is positively regulated by Nodal signals. In vivo functional studies in zebrafish suggest that Dpr2 suppresses mesoderm induction activities of Nodal signaling. Dpr2 is localized in late endosomes, binds to the TGFbeta receptors ALK5 and ALK4, and accelerates lysosomal degradation of these receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Lixia -- Zhou, Hu -- Su, Ying -- Sun, Zhihui -- Zhang, Haiwen -- Zhang, Long -- Zhang, Yu -- Ning, Yuanheng -- Chen, Ye-Guang -- Meng, Anming -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):114-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Developmental Biology, Ministry of Education (MOE), Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15459392" target="_blank"〉PubMed〈/a〉

    Description: In a magnetic coupling resonant wireless power transfer (MCR-WPT) system, energy is transferred between transmitter and receiver coils with same natural resonant frequency ω 0 . Studying energy transfer mechanism is the theoretical basis of MCR-WPT control. This paper takes the MCR-WPT system with two coils as the research object. Firstly, the model of the system is established. Then, combined with the theory of waves, the change of the capacitor charge of the two resonant circuits is analysed, which is drawn up during the linear superposition of two different frequency modes and is also a modulation wave with a specific system resonant frequency ω s as the carrier frequency and ω Δ as the modulation frequency. Where ω s is different from ω 0 . Next, the energy of the two resonant circuits is analysed, which is transferred with the beat frequency 2 ω Δ . Finally, ANSYS Simplor...

    Description: The Chelungpu fault ruptured during the September 1999 Mw 7.6 Chi-Chi earthquake, in Central Taiwan. This event was characterized by coseismic displacements that increase along-strike and updip, from south to north. This variation in coseismic slip appears correlated to the geometry and segmentation of the thrust fault. Previous studies suggested that such variations may also exist in the long-term fault slip rate, but this aspect has not yet been clearly documented. To address this issue, we investigate deformed fluvial terraces along the Choushui and Tatu-Wu rivers, in the southern and central segments of the thrust fault. Optical ages (OSL) of ~13 ka to ~38 ka obtained for these terraces enable estimation of fault slip rates of 5.8 ± 2.0 and 10.3 + 1.6/-3.0 mm/yr for the southern and central segments, respectively. We combine these findings with the fault slip rate determined by other authors for the northern segment. Statistical analysis of the data suggests lateral variations in the long-term slip rate of the Chelungpu fault, with slip rates increasing towards the north. This pattern in the slip rate averaged over ~10s kyr is similar to that observed for coseismic displacements during the 1999 Chi-Chi earthquake. The similarities in the deformation pattern observed for one earthquake or cumulated over several events suggest that the ChiChi earthquake could be characteristic of the earthquakes breaking the Chelungpu fault, with respect to slip distribution. Such similarities are probably related to the physical properties of the fault zone. Our results also allow for discussing the plausible evolution of major rivers draining the foothills of central Taiwan over the last ~40-60 kyrs.

    Notes: A high current O+ ion source is desirable for applications to SIMOX and materials modification. To meet the requirements of this field, a new type of nonfilament high current O+ ion source has been developed successfully in our institute. Using O2 as discharge material, the typical extraction characteristics are as follows: The total oxygen ions current is 100 mA, of which the content of O+ is 80%, beam current density is larger than 200 mA/cm2 when the power consumption is 100 W; therefore the economic property is 1 mA/W. Feeding N2, the total extraction beam current is 100 mA of which 70% is N+ while the power consumption is 135 W.
