The ef.ect of.repeated melting of.the mother ingot on the thermal stabilityof.a Zr_(60)Al_+(15)Ni_(25) glassy alloy was investigated by dif.erential scanning calorimetry(DSC). Experimental results indicate that af.er the repeated melting of.the ingots at 1300 and 1580K, the glass transition temperature T_g increases f.om 686.4 to 690.7 and 696.8 K and the onsettemperature of.crystallization T_x f.om 757.9 to 758.6 and 763.4 K, respectively, indicating thatthe thermal stability becomes higher af.er the repeated arc melting of.the mother ingot and that itis more ef.ective at higher temperature. Within the f.amework of.structure heredity, the origin of.he improvement of.the thermal stability of.Zr_(60)Al_+(15)Ni_(25) bulk glassy alloy is discussed.

The genetic mechanism of.the 5.12 Wenchuan Earthquake is still being debated and there is still no convincing general explanation f.r most of.the phenomena. This is because researchers have ignored the important role of.the Minshan block in the seismogenic process. The authors present a new opinion based on geological survey and comprehensive analyses. The Minshan block is a key tectonic element of.the earthquake occurrence in the northwest triangle f.ulty block of.Sichuan Province. The Minshan block is bordered by Longmen Mountain Range f.actures in the south, the Huya f.acture in the east, the Tazang f.acture in the north and the Mounigou Valley f.acture in the west. The rigidity of.the block is relatively larger than those of.the adjacent regions. The block's eastward movement pushed by regional maximum main geo-stress is limited when it suddenly tapers of. near the east triangle end with a bottle-neck ef.ect, and this causes geo-stress concentration around it. The shape of.the block is cof.in-like, wide in the upper part and narrow in the lower part. When a strong earthquake occurs along the block margins, the lock-up ef.ect temporarily released, resulting in geo-stress transmitted to the Pingwu-Qingchuan (Motianling block) region. This transmission caused the Wenchuan earthquake's af.ershocks to be concentrated in Qingchuan region. As the block moved eastward, the back of.the block, i.e. the south segment of.Mounigou Valley f.acture, became active af.er the Wenchuan Earthquake. Theref.re the af.ershocks were concentrated along the south segment of.Mounigou Valley f.acture. Because the south margin is composed of.the f.ont range f.acture, the geo-stress gradually released, causing many af.ershocks along the Guanxian-Anxian f.acture. The geological survey made af.er the Wenchuan Earthquake reveals that the surf.ce ruptures in the south margin of.Minshan block occur not along the Beichuan-Yingxiu f.acture (central f.acture) also along the f.ont range f.acture.

high-resolution non-emissive displays based on electrochromic tungsten oxides (WOx) are crucial f.r f.ture near-eye virtual/augmented reality interactions, given their impressive attributes such as high environmental stability, ideal outdoor readability, and low energy consumption. However, the limited intrinsic structure of.inorganic materials has presented a signif.cant challenge in achieving precise patterning/pixelation at the micron scale. Here, we successf.lly developed the direct photolithography f.r WOx nanoparticles based on in situ photo-induced ligand exchange. This strategy enabled us to achieve ultra-high resolution ef.iciently (line width m, the best resolution f.r reported inorganic electrochromic materials). Additionally, the resulting device exhibited impressive electrochromic perf.rmance, such as f.st response (high coloration ef.iciency (119.5 cm(2) C-1), good optical modulation (55.9%), and durability (> 3600 cycles), as well as promising applications in electronic logos, pixelated displays, f.exible electronics, etc. The success and advancements presented here are expected to inspire and accelerate research and development (R&D) in high-resolution non-emissive displays and other ultra-f.ne micro-electronics.

In the Tibet ancient buildings, there are large amounts of.combustible decorative textiles that pose great potential f.re hazards. Some typical textile samples were collected f.om the Potala Palace. Their combustion properties were analyzed by UL 94 Vertical Burning test and Limiting Oxygen Index test. The ef.ects of.plateau climate on combustion properties, an important f.ct required to be considered in the f.ame retarding design f.r combustible textiles, were preliminarily compared via test data in the plain and those in the plateau. Based on the f.regoing analyses, some thoughts were presented on the clean and f.asible f.ame retarding means f.r the decorative textiles due to their special applications in Tibet, in ancient buildings and in plateau climate. The f.re resistance, weather resistance, UV resistance, endurance, ornamentation and religious perf.rmances f.r these textiles must be taken into considerations comprehensively in the designs.

A syntactic and structural matching mechanism f.r service discovery was put f.rward, which tries to exploit the underlying semantics of.web services to enhance tbe traditional syntactic service discovery. We commit WSDL （Web Service Description Language） as service description language. The syntactic matching mechanism is based on the textual similarity among WSDL documents using VSM （ Vector Space Model）. The structural inf.rmation is extracted f.om WSDL document tree or the invocation sequence of.a series of.services which can be viewed as the problem of.graph isomorphism. Then we combine the syntactic and structural similarity linearly to calculate the service similarity. f.nally we provide a novel web services discovery f.amework named SG^＊ to f.nd the exact services meeting the users＇ goals based on service similarity.

Gold nanorods（AuNRs） are excellent photothermal agents to enable a variety of.laser stimulated f.nctional polymers. One key issue is to maximize the photothermal conversion ef.iciency of.Au NRs. In this study, the light responsive AuNR/shape memory polymer（SMP） nanocomposites with inclusion of.AuNRs of.varied aspect ratios were prepared, characterized, and their laser irradiation induced bending behavior was investigated. The critical role of.the on-resonance irradiation condition—a close match of.the longitudinal plasmon resonance of.the AuNR with the wavelength of.the incident laser—has been *** allows f.r maximizing the photothermal conversion ef.iciency of.AuNRs to result in the rapid and large def.rmation of.the AuNR/SMP nanocomposites. f.r the Au NR/SMP nanocomposite f.lms prepared under similar processing conditions, the close-to-resonance irradiation at a 1.27 W/cm^2 was able to induce a bending rate of.27？/s and maximum bending angle of.90.4？. In contrast, the of.-resonance irradiation at a 1.89 W/cm^2 resulted in negligible response.
