    Chen, Ruey-Shun   Hu, Yu-Xi   Chen, Yeh-Cheng   Horng, Shi-Jinn   Fan, Xiaopeng   Chen, S. P.   Xiong, Naixue  

    This study is based on RFID technology to detect the locations of medical care personnel and patient who move around indoors; meanwhile, wearable and mobile physiological signal detection suite technique is associated to monitor the physiological status of the patient at any time. Through the positioning message of RFID, the computer system can assign medical care personnel that is nearest to the patient at emergency accident to perform medical care. Furthermore, through the use of wireless mobile device, it can be ensure that medical care personnel can obtain any emergency message of the patient at any time. Through integration of three techniques such as RFID technique, physiological signal detection suite technique and wireless mobile device, a set of emergency medical care system structure is designed in this study. Meanwhile, based on this system structure, a prototype system is developed to verify the feasibility of this system structure. Through the emergency medical care system developed in this study, no matter when and where emergency accident occurs, medical care personnel can reach the patient at the emergency accident site in the shortest time to reduce the possibility of delayed medical care.

    During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new pixel layer, the Insertable B-Layer (IBL), was to maintain or improve the robustness and performance of the ATLAS tracking system, given the higher instantaneous and integrated luminosities realised following the shutdown. Because of the extreme radiation and collision rate environment, several new radiation-tolerant sensor and electronic technologies were utilised for this layer. This paper reports on the IBL construction and integration prior to its operation in the ATLAS detector.

  • Halo Formation in Binary Fe-Nb Off-eutectic Alloys

    Li, K. W.   Wang, X. B.   Li, S. M.   Wang, W. X.   Chen, S. P.   Gong, D. Q.   Cui, J. L.  

    In the Fe-Fe2Nb eutectic system, halo formations were observed at both the hypo- and hypereutectic compositions. This observation cannot be well explained by the existing halo theories based on competitive growth or competitive nucleating alone. In the present paper, a new explanation is proposed to describe the formation of halos in the binary Fe-Fe2Nb off-eutectic alloys. By theoretical calculations, the alpha-Fe and Fe2Nb are predicted to be the primary growing phase in the hypo- and hypereutectic compositions, respectively. Based on the experimental observations, the Fe2Nb Laves phase was identified as a good nueleant for alpha-Fe phase, but not vice versa. By analysing of the competitive growth among the involved phases and the growth undercoolings of the two individual eutectic phases, the formation of halos in the Fe-Fe2Nb alloys is explained successfully.

  • crAssphage is not associated with diarrhoea and has high genetic diversity

    Liang, Y. Y.   Zhang, W.   Tong, Y. G.   Chen, S. P.  

    crAssphage is a newly discovered gut bacteriophage. However, its pathogenicity and molecular epidemiology in humans are as yet unclear. In this study, we investigated the association between crAssphage and diarrhoea, as well as the molecular epidemiology of crAssphage in Chinese patients from our hospital. Our results indicated that there were no significant differences in the crAssphage-positive ratio and viral loads in faecal supernatants between adults with diarrhoea and healthy adults. Of infants and children with diarrhoea, 2.8% were found to be crAssphage-positive, including two infants aged <1 month. Markedly, of all confirmed crAssphage- positive strains, 100% had the ORF00039 deletion and 77.8% had low identity of ORF00018 compared to crAssphage (GenBank accession no. NC_ 024711, designated genotype 1). Thus, crAssphage was not associated with diarrhoea and most strains of crAssphage in Chinese patients (designated genotype 2) were characterized by the ORF00039 deletion and low identity of ORF00018.

    Chen, H. W.   Chen, S. P.   Hou, J.  

    Combine a section of photonic crystal fiber and a picosecond fiber laser to realize an all-fiber supercontinuum source. The picosecond laser exhibits 20 W average output power, 14 ps pulse duration at 480MHz repetition rate. Approximately 7 W supercontinuum with over 1100 nm spectral range is obtained with an optical-optical conversion efficiency of 34%. Further improvements for higher average power are discussed in this paper.

  • Crystal Structures of Two Organic Salts of 1,2,3,4-Tetrahydro-1,10-phenanthroline1

    Zheng, Y.   Yi, H. P.   Song, B. H.   Chen, S. P.  

    Two organic salts of 1,2,3,4-tetrahydro-1,10-phenanthroline (tphen), namely (oaH)(tphenH) (1) and (ssa)(tphenH)center dot H2O (2) (oaH(2) is oxalic acid, ssaH is 5-sulfosalicylic acid), were synthesized and structurally characterized. Both compounds contain tphenH(+) cations but illustrate different crystal structures. The tphenH(+) cations show a cross-stacking packing model in 1 but display a herringbone packing model in 2.

  • Correlation-induced anomalies and extreme sensitivity in fcc Pu

    Chen, S. P.  

    GGA+U density functional theory was used to study the effects of correlation on the properties of fcc Pu. The structural and elastic properties of fcc Pu are found to be highly sensitive to the Hubbard U parameter. Within an interval of 0.1 eV of the U parameter, the equilibrium lattice constants of fcc Pu can change from 0.44 to 0.47 nm. Whereas the bulk modulus can drop by a factor of 5-10, the pressure derivative, dB/dp, of the bulk modulus can rise dramatically from 5 to 16 and then drop discontinuously to a negative value before recovering to a more normal value. These observations are partially supported by existing experiments and the prediction of a negative dB/dp needs to be tested in future experiments. The 5f electron occupancy number also shows a drastic change near the transition range that clearly separates the delocalized and localized electron regions.

  • Surface structure of cleaved (001) USb(2) single crystal RID D-7212-2011

    Chen, S. P.   Hawley, M.   Van Stockum, P. B.   Manoharan, H. C.   Bauer, E. D.  

    We have achieved what we believe to be the first atomic resolution scanning tunneling microscopy (STM) images for a uranium compound USb(2) taken at room temperature. The a, b, and c lattice parameters in the images confirm that the tetragonal USb2 crystals cleave on the (001) basal plane as expected. Our calculations indicate a symmetric cut between Sb planes to be the most favorable cleavage plane and U atoms to be responsible for most of the density of states measured by STM. Since the spacing between Sb atoms and between U atoms is the same, STM topography alone cannot unambiguously identify the surface atom species.

  • Microstructure and properties of Fe-Cr-C hardfacing alloys reinforced with TiC-TiB2

    Liu, H. Y.   Yu, F. B.   Meng, Q. S.   Chen, S. P.   Wang, H.  

    Different amounts of TiB2 powder were added to flux cores of wear resistant hardfacing flux cored wires for the preparation of new flux cored wires. Fe-Cr-C hardfacing alloys reinforced with TiB2 were produced by arc hardfacing. The microstructure, hardness and wear resistance behaviour of the hardfacing alloys were investigated using an optical micrograph, scanning electron micrograph (SEM), X-ray diffractometer, macrohardness tester, microhardness tester and abrasive wear tester. The results showed that, among the hardfacing alloys, a new hard phase, i.e. TiC-TiB2 composite compound particles, was formed and dispersed in the primary carbides and matrix structures. The TiC-TiB2 reinforced Fe-Cr-C hardfacing alloys imparted greater hardness and better wear resistance. The presence of TiC-TiB2 hard phase particles is the main reason for the improvement in hardness and wear resistance of Fe-Cr-C hardfacing alloys.

  • Passively mode-locked fiber ring laser using semiconductor saturable absorber mirror

    Liu, P. Z.   Hou, J.   Zhang, B.   Chen, S. P.   Chen, J. B.  

    We experimentally demonstrate a fiber laser passively mode-locked by a semiconductor saturable absorber mirror (SESAM) in a ring cavity. A pulse series with a temporal width of 1 ns is generated at a repetition rate of 12.3 MHz. With careful polarization adjustment, the pulse width decreases, the peak power increases and the spectral sidebands are formed in the optical spectrum. The reason of the phenomenon above has been analyzed. In addition, the characteristic of the pulse with different length of the Er(3+) Doped Fiber (EDF) is studied and the results show that it is reabsorption that causes the laser to shift to longer wavelength direction when the EDF length increases.

  • Application of compact Non-Evaporable Getter and Sputter combination in UHV system of HIAF

    Luo, C.   Li, P.   Xie, W. J.   Wan, Y. P.   Chai, Z.   Zhu, X. R.   Meng, J.   Chen, S. P.   Yang, W. S.  

    HIAF-BRing, a new multi-purpose accelerator facility of the High Intensity Heavy-Ion Accelerator Facility project, requires an extremely high vacuum lower than 10(-9) Pa to fulfill the requirements of radioactive beam physics and high energy density physics. Use of large speed Titanium sublimation pump (TSP) in combination with Sputter ion pumps (SIP) is not always feasible due to space limitations. A novel combination pump, based on Non Evaporable getter (NEG) and a 101/s SIP (NEXTorr (R) D 2000-10) has been evaluated as it provides large speed in a more compact design. The two combination pumps (TSP + SIP and NEXTorr D 2000-10) have been tested by dynamic flow method to measure the ultimate pressure, the pumping speed and the suitability for HIAF. Test results show that both combination pumps can be used in the pressure range of 10(-10) Pa. The ultimate pressure of TSP + SIP combination pump is slightly lower than NEXTorr D 2000-10, but the latter one has much larger sorption capacities (H-2: 210200 Pa l vs 265 Pa. l; CO: 430 Pa.l vs 24 Pa. l), which means it is applicable to a wider pressure range. At the same time, after twenty activation cycles, the initial pumping speed of NEXTorr D 2000-10 for H-2 and CO decreased less than 10% as compared with the initial pumping speed of the first activation, which meets the actual vacuum system requirement of HIAF. A dedicated vacuum chamber with collimator and NEXTorr D 2000-10 has been designed and manufactured to stabilize the dynamic vacuum by decreasing the heavy ion induced gas desorption and increasing the gas pumping speed. The static and dynamic vacuum pressure evolution has been simulated to verify the feasibility of the NEXTorr D 2000-10 used in the HIAF-BRing.

  • Thermochemistry of europium and dithiocarbamate complex Eu(C5H8NS2)(3)(C12H8N2)

    Chen, S. P.   Meng, X. X.   Shuai, Q.   Jiao, B. J.   Gao, S. L.   Shi, Q. Z.  

    A solid complex Eu(C5H8NS2)(3)(C12H8N2) has been obtained from reaction of hydrous europium chloride with ammonium pyrrolidinedithiocarbamate (APDC) and 1,10-phenanthroline (o-phen center dot H2O) in absolute ethanol. IR spectrum of the complex indicated that Eu3+ in the complex coordinated with sulfur atoms from the APDC and nitrogen atoms from the o-phen. TG-DTG investigation provided the evidence that the title complex was decomposed into EuS. The enthalpy change of the reaction of formation of the complex in ethanol, Delta H-r (theta)(m)(l), as -22.214 +/- 0.081 kJ mol(-1), and the molar heat capacity of the complex, c (m), as 61.676 +/- 0.651 J mol(-1) K-1, at 298.15 K were determined by an RD-496 III type microcalorimeter. The enthalpy change of the reaction of formation of the complex in solid, Delta H-r(m)theta(s), was calculated as 54.527 +/- 0.314 kJ mol(-1) through a thermochemistry cycle. Based on the thermodynamics and kinetics on the reaction of formation of the complex in ethanol at different temperatures, fundamental parameters, including the activation enthalpy (Delta H-f(not equal)theta), the activation entropy (Delta S-not equal(theta)), the activation free energy (Delta G(not equal)(theta)), the apparent reaction rate constant (k), the apparent activation energy (E), the pre-exponential constant (A) and the reaction order (n), were obtained. The constant-volume combustion energy of the complex, Delta o(c)U, was determined as -16937.88 +/- 9.79 kJ mol(-1) by an RBC-II type rotating-bomb calorimeter at 298.15 K. Its standard enthalpy of combustion, Delta o(c)H(m)(theta), and standard enthalpy of formation, Delta o(f)H(m)(theta), were calculated to be -16953.37 +/- 9.79 and -1708.23 +/- 10.69 kJ mol(-1), respectively.

  • Ordered YBCO sub-micron array structures induced by pulsed femtosecond laser irradiation

    We report on the formation of organized sub-micron YBa(2)Cu(3)O(7) (YBCO) dots induced by irradiating femtosecond laser pulses on YBCO films prepared by pulse laser deposition with fluence in the range of 0.21 similar to 0.53 J/cm(2). The morphology of the YBCO film surface depends strongly on the laser fluences irradiated. At lower laser fluence (similar to 0.21 J/cm(2)) the morphology was pattern of periodic ripples with sub-micrometer spacing. Slightly increasing the laser fluence to 0.26 J/cm(2) changes the pattern into organized sub-micron dots with diameters ranging from 100 nm to 800 nm and height of 150 nm. Further increase of the laser fluence to over 0.32 J/cm(2), however, appeared to result in massive melting and led to irregular morphology. The mechanism and the implications of the current findings will be discussed. Arrays of YBCO sub-micron dots with T(c) = 89.7 K were obtained. (C) 2008 Optical Society of America

  • Immune responses to foot-and-mouth disease virus in pig farms after the 1997 outbreak in Taiwan

    Chen, S. P.   Sun, Y. F.   Lee, M. C.   Cheng, I. C.   Yang, P. C.   Huang, T. S.   Jong, M. H.   Robertson, I. D.   Edwards, J. R.   Ellis, T. M.  

    This paper reports on a retrospective study of the antibody responses to structural and non-structural proteins of FMD virus O Taiwan 97 in six pig herds in Taiwan in the year after the 1997 Taiwanese FMD outbreak. All herds were vaccinated against FMD after the outbreak as part of the countrywide control program. Three of the herds had confirmed FMD infections (herds N, O and P) and three herds remained non-infected (herds K, L and M). The serum neutralizing antibody titers and the non-structural protein ELISA (NSP) antibody responses in sows and 1-month-old pigs in the infected herds were higher than in the non-infected herds, but over time a number of positive NSP reactors were detected. From the serological studies and the herd monitoring and investigations it was considered that the FMD NSP positive reactors may not have constituted a true reservoir of FMD virus infection especially in herds where susceptible pigs were no longer present post-exposure or post-vaccination. Pigs vaccinated with an unpurified FMD type O vaccines being used at that time also showed false positive responses for NSP antibodies. (C) 2007 Elsevier B.V. All rights reserved.
