Wearable systems that monitor muscle activity, store data and deliver feedback therapy are the next frontier in personalized medicine and healthcare. However, technical challenges, such as the fabrication of high-performance, energy-efficient sensors and memory modules that are in intimate mechanical contact with soft tissues, in conjunction with controlled delivery of therapeutic agents, limit the wide-scale adoption of such systems. Here, we describe materials, mechanics and designs for multifunctional, wearable-on-the-skin systems that address these challenges via monolithic integration of nanomembranes fabricated with a top-down approach, nanoparticles assembled by bottom-up methods, and stretchable electronics on a tissue-like polymeric substrate. Representative examples of such systems include physiological sensors, non-volatile memory and drug-release actuators. Quantitative analyses of the electronics, mechanics, heat-transfer and drug-diffusion characteristics validate the operation of individual components, thereby enabling system-level multifunctionalities.

Qiao, X.,Cheng, Y.,Qin, L.,Qin, C.,Cai, P.,Kim, S.I.,Seo, H.J. Elsevier Sequoia 2014 JOURNAL OF ALLOYS AND COMPOUNDS Vol.617 No.-

Micro-sized phosphors of Eu<SUP>3+</SUP>-doped NaBaBO<SUB>3</SUB> (0.5-12mol%) were prepared by the modified co-precipitation synthesis. The samples were characterized by scanning electron micrograph (SEM) images and electron dispersive X-ray (EDX). The polycrystalline samples are well developed to the regular plate-like particles with the uniform morphology. The single crystal-phase NaBaBO<SUB>3</SUB> of the Eu<SUP>3+</SUP>-doped sample was confirmed by X-ray powder diffraction (XRD) measurements and the structure refinement. The optical properties are evaluated by photoluminescence (PL) excitation and emission spectra, and decay curves. The absolute luminescence quantum efficiency (QE) and the activation energy (ΔE) are reported. Eu<SUP>3+</SUP>-doped NaBaBO<SUB>3</SUB> presents a bright red-emitting color under the excitation of near-UV light around 400nm. The maximum absolute QE of NaBaBO<SUB>3</SUB>:Eu<SUP>3+</SUP> is estimated to be 53% at 300K. The phosphor shows an excellent thermal stability on temperature quenching effects. The results were discussed on the relationship between the structure and the luminescence properties.

Qiao, H.,Guo, X.Q.,Hong, S.G.,Wu, P.D. Elsevier 2017 Journal of alloys and compounds Vol.725 No.-

<P><B>Abstract</B></P> <P>The deformation characteristics of rolled Mg alloy AZ31, which was previously compressed along the rolling direction and then re-compressed along the transverse direction, have been numerically investigated. Secondary/double twinning is allowed in the current EVPSC-TDT model, and {10-12}-{10-12} secondary twinning is found to play an important role in reproducing the experimental data. The deformation behavior of the pre-compressed materials associated with primary and secondary twining has been interpreted in terms of the predicted activities, twin volume fractions and texture evolutions. The {10-12}-{10-12} secondary twinning in the previously twinned region is most active for the 9% pre-compressed material while primary twinning within the residual un-twinned domain dominates twinning behavior for the 3% pre-compressed material.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The EVPSC model is first extended to simulate the {10-12}-{10-12} twinning. </LI> <LI> The deformation behavior of the pre-compressed materials has been interpreted. </LI> <LI> {10-12}-{10-12} twinning plays a key role in reproducing the experimental data. </LI> </UL> </P>

Identification of Quantitative Trait Loci for Cold Response of Seedling Vigor Traits in Rice

Han, L.,Qiao, Y.,Zhang, S.,Zhang, Y.,Cao, G.,Kim, J.,Lee, K.,Koh, H. Science press ; Elsevier 2007 Journal of genetics and genomics Vol.34 No.3

The quantitative trait loci (QTLs) for the seedling vigor traits under 12<SUP>o</SUP>C cold water irrigation, such as the seedling height, the seedling fresh weight, the seedling dry weight, and their cold response index, were identified using an F<SUB>2-3</SUB> population including 200 individuals and lines derived from a cross of indica and japonica ''Milyang 23/Jileng 1'' with microsatellite markers. All seedling vigor traits exhibited a continuous distribution near normal in F3 lines; these traits were quantitative traits controlled by multiple genes. Twelve QTLs conferring the seedling vigor traits under cold water irrigation were detected on chromosomes 1, 2, 7, 8, and 12, which explained the observed phenotypic variance from 5.2% to 17.9%. Among them, qCSH2 and qCSH12 were located in RM262-RM263 on chromosome 2 and RM270-RM17 on chromosome 12, respectively, which were associated with the seedling height. qSDW12 and qCSDW1 were located in RM19-RM270 on chromosome 12 and RM129-RM9 on chromosome 1, respectively, which were correlated with the seedling dry weight and its cold response index, and the explained 16.6%, 17.9%, 15.9%, and 16.2% of the observed phenotypic variation, respectively. These QTLs alleles were derived from cold-tolerant parent Jileng 1; the gene actions of the two front genes showed their additive effect, and the two genes belind showed dominant and over dominant effects, respectively.

Li, Defa,Qiao, S.Y.,Yi, G.F.,Jiang, J.Y.,Xu, X.X.,Thacker, P.,Piao, X.S.,Han, In K. Asian Australasian Association of Animal Productio 2000 Animal Bioscience Vol.13 No.1

Two experiments were conducted to determine ileal digestibilities for the amino acids contained in rapeseed meal using the regression technique and then applying the values obtained, in a growth trial, using growing-finishing pigs. For the digestibility trial, four 20 kg crossbred $(Yorkshire{\times}Landrace{\times}Beijing\;Black)$ barrows were fitted with simple T-cannula in the terminal ileum. After recovery, the barrows were fed one of four experimental diets according to a $4{\times}4$ Latin Square design. The pigs were fed corn-soybean meal based diets supplemented with 0, 25, 50 or 75% rapeseed meal. For the growth trial, 80 crossbred $(Yorkshire{\times}Landrace{\times}Beijing\;Black)$ growing pigs $(20{\pm}2.4kg)$ were fed corn-soybean meal diets supplemented with 0, 3, 6, 9 or 12% rapeseed meal. Four pens (2 gilts and 2 castrates) were assigned to each treatment. With the exception of isoleucine and methionine, the digestibility coefficients for the indispensible amino acids declined as the level of rapeseed meal in the diet increased. There was little agreement between the amino acid digestibilities determined with the regression technique and values previously published for rapeseed meal. During the growing (22-42 kg) period, the addition of rapeseed meal had no significant effects on gain, feed intake or feed conversion. During the finishing period (58-91 kg), daily gain was not affected by rapeseed meal inclusion but feed conversion declined (p<0.04) as the level of rapeseed meal in the diet increased.

Study on mechanical behaviors of cable-supported ribbed beam composite slab structure during construction phase

W.T. Qiao,Q. An,D. Wang,M.S. Zhao 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.21 No.1

The cable-supported ribbed beam composite slab structure (CBS) is a new type of pre-stressed hybrid structure. The standard construction method of CBS including five steps and two key phases are proposed in this paper. The theoretical analysis and experimental research on a 1:5 scaled model were carried out. First, the tensioning construction method based on deformation control was applied to pre-stress the cables. The research results indicate that the actual tensile force applied to the cable is slightly larger than the theoretical value, and the error is about 6.8%. Subsequently, three support dismantling schemes are discussed. Scheme one indicates that each span of CBS has certain level of mechanical independence such that the construction of a span is not significantly affected by the adjacent spans. It is shown that dismantling from the middle to the ends is an optimal support dismantling method. The experimental research also indicates that by using this method, the CBS behaves identically with the numerical analysis results during the construction and service.

Bioefficacy of Lysine from L-lysine Sulfate and L-lysine⋅HCl for 10 to 20 kg Pigs

Liu, M.,Qiao, S.Y.,Wang, X.,You, J.M.,Piao, X.S. Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.10

The objective of this study was to compare the bioefficacy of L-lysine sulfate relative to L-lysine${\cdot}$HCl for 10 to 20 kg pigs. Two experiments were conducted to determine the bioefficacy of the two sources of lysine using daily gain, feed conversion, plasma urea nitrogen and nitrogen retention as the response criteria. In experiment 1, 168 crossbred barrows ($Landrace{\times}Large$ White), weaned at $28{\pm}3$ d ($9.07{\pm}0.78$kg body weight), were allotted to one of seven dietary treatments in a $2{\times}3$ (two lysine $sources{\times}three $ lysine levels) factorial arrangement of treatments with an added negative control treatment group. The basal diet was based on corn, peanut meal and soybean meal and provided 0.67% lysine. The basal diet was supplemented with 0.1, 0.2 or 0.3% lysine equivalents supplied from either L-lysine sulfate or L-lysine${\cdot}$HCl. Each treatment was fed to six pens of pigs with four pigs per pen. The trial lasted 21 days. The relative bioefficacy value of lysine in L-lysine sulfate using daily gain, feed conversion and plasma urea nitrogen as response criteria was 1.01, 1.05 and 1.04 of the lysine in L-lysine${\cdot}$HCl, respectively. In experiment 2, 42 crossbred ($Landrace{\times}Large$ White) pigs ($16.03{\pm}1.58$ kg body weight) were housed in stainless steel metabolism cages for 10 d and fed the seven diets used in the nitrogen-balance trial. The relative bioefficacy value of L-lysine sulfate was estimated to be 0.95 as effective as L-lysine${\cdot}$HCl for nitrogen retention on an equimolar basis. The t-test analysis revealed that bioefficacy of lysine in L-lysine sulfate was not significantly different from lysine in L-lysine${\cdot}$HCl, which was set at 1.00. In conclusion, L-lysine sulfate can be used instead of L-lysine${\cdot}$HCl to fortify lysine-deficient diets fed to 10 to 20 kg pigs.
