    ABSTRACT: The long-standing problem of dislocation-preferential dissolution in a crystal has been generally ascribed to the distortion energy stored in the vicinity of the dislocation core. However, due to lack of experimental means, the relationship between the local distortion state and the electrochemical behaviour of a single dislocation has not been established so far. via in situ ex-environment transmission electron microscopy (TEM), we demonstrate that the emergences of both edge and screw dislocations on MnS surfaces are the preferential sites for dissolution of the MnS inclusions within a stainless steel. In addition, we map the strain-induced variation of the standard electrode potential around the edge dislocation by a combination of the aberration-corrected high-resolution TEM and strain-analysis-based mechanochemistry theory. Significantly, our report provides a new approach to investigate the strain–corrosion correlation at an atomic scale.

    ABSTRACT: Coincident with economic development, China has experienced a marked transition from undernutrition to overweight/obesity over the last few decades. We aimed to explore the burden of under- and overnutrition and nutrient adequacy among 2-12-year-old Chinese children. We included anthropometry, dietary intake and biomarkers from 2-12-year-olds who participated in the 2009-2011 China Health and Nutrition Survey (n=1191 in 2009; n=1648 in 2011). Dietary intakes were compared with the 2013 Chinese Dietary Recommended Intakes. In 2011, ~19% of 2-6-year-old children were underweight, 4% were stunted, 10% were overweight and 12% were obese. Among 7-12-year-old children, stunting was almost 0%, whereas ~21% were underweight, 13% were overweight and 6% were obese in 2011. Overweight and obesity were more prevalent among children from urban areas and higher income households. In particular, 2-6-year-old children from urban areas and higher income households experienced the highest increase in obesity from 2009 to 2011 (P<0.05). Children from urban areas and higher income households had overall higher intakes of total daily energy and most macro- and micronutrients (P<0.05). However, a significant proportion of children did not meet the recommendations for important micronutrients. Underweight and stunting currently coexist with overweight and obesity among Chinese children <12-year-old. We found critical disparities in the prevalence of under- and overweight/obesity, as well as in nutrient intakes and dietary adequacies between children from different incomes, revealing that the burden of childhood under- and overnutrition may constitute a public health concern in modern China.European Journal of Clinical Nutrition advance online publication, 1 July 2015; doi:10.1038/ejcn.2015.106.

    ABSTRACT: By analyzing Rc and Ic light curves of the short-period solar-type eclipsing binary GSC 1537-1557 we discovered that it is a shallow contact binary with a degree of contact factor of . Photometric solutions reveal that GSC 1537-1557 is a W-type system with a mass ratio of where the less massive component (the primary star) is about 110 K hotter than the more massive one (the secondary star). The asymmetry and variation of the light curves were explained as the activity of spots on the solar-type component stars. By investigating all of the available times of light minima, we found that the observed-calculated (O-C) curve shows a cyclic variation with a small amplitude of 0.00335 days and a period of 8.1 years. The small-amplitude cyclic change in the curve was analyzed for the light-travel time effect via the presence of an extremely cool stellar companion. The mass of the third body was determined to be when is adopted for GSC 1537-1557. The semimajor axis of the outer obit is AU.

    ABSTRACT: The multiscale Ni/Cu laminated composites with different layer-thickness ratios and grain sizes were designed and prepared by the dual-bath electrodeposition technique. Strength and ductility of the multiscale Ni/Cu laminated composites were investigated by tensile tests at room temperature. The experimental results show that the ultrafine-grained Ni/coarse-grained Cu laminated composites with a thickness ratio of 20:1 have a good synergy of strength and ductility. For this Ni/Cu laminated composite, not only could the large strain hardening ability and the good plastic deformation stability of the thick ultrafine-grained Ni layers be obtained, but also the ductility of the ultrathin coarse-grained Cu layers and the resistance to the development of strain localization of the ultrafine-grained Ni layers did not become degraded. Basic mechanisms for optimizing the strength and the ductility in the multiscale Ni/Cu laminated composites are discussed.

    ABSTRACT: New CCD photometric light curves of the low-mass binary system NSVS 10653195 are presented. Our complete B, V, Rc and Ic-band light curves show a remarkable out-eclipsing distortion. This phenomenon suggests that the components of the system may be active. The photometric solutions with star-spot were derived by using the 2013 version of the Wilson-Devinney (WD) code. Based on all available times of light minimum, we analyzed the orbital period changes. The diagram reveals that the period of NSVS 10653195 is decreasing at a rate of dP/dt=-2.79 × days yr which is probably caused by angular momentum loss.

    ABSTRACT: The environmental and behavioral risk factors associated with central obesity and/or inflammation in populations exposed to both obesogenic and pathogenic environments remain unclear. We tested which of the characteristics distinguished 3 risk groups-high waist-to-height ratio (WHtR; >0.5) without inflammation [high-sensitivity C-reactive protein (hs-CRP) <3 mg/L], normal WHtR (≤0.5) with inflammation (hs-CRP: 3-10 mg/L), and high WHtR with inflammation-from the referent group with normal WHtR without inflammation and, secondarily, which factors differed between the groups with high WHtR with and without inflammation. The analytic sample included 8068 adults participating in the China Health and Nutrition Survey in 2009. Adjusted multinomial and logistic regression models were used to assess the risk of being in one of the "unhealthy" groups compared with the referent group. Men with high WHtR with and without inflammation were more likely to live at higher urbanicity (57-63%) and have higher incomes (26-42%) and household sanitation (26-67%) and were >40% less likely to have high physical activity than the healthy referent group. Men with high WHtR with inflammation had higher odds of infectious symptoms than those with high WHtR without inflammation (OR: 1.73; 95% CI: 1.15, 2.61). Women with high WHtR without inflammation were less likely to have high household sanitation (44%) or perform high levels of physical activity (24%) and were 34% more likely to consume more fiber than the healthy referent group. Women with high WHtR and inflammation were more likely than those with high WHtR without inflammation to have infectious symptoms (OR: 1.45; 95% CI: 1.01, 2.07) and less likely to have higher fiber intake (OR: 0.77; 95% CI: 0.60,1.00) or physical activity (OR: 0.55; 95% CI: 0.41, 0.73). These results document different underlying pathogenic and obesogenic risk factors for visceral adiposity with and without inflammation in Chinese adults, suggesting that context-specific approaches may be needed to prevent and treat inflammation. © 2015 American Society for Nutrition.

    ABSTRACT: We clearly show that fatigue-induced grain growth is suppressed in the annealed nanocrystalline Cu films, which leads to the enhanced resistance to fatigue cracking compared with that of the as-deposited ones. Annealing-stabilization of the nanograin boundaries may provide a potential way to enhance fatigue reliability of nanoscale film-based flexible devices.

    ABSTRACT: The metastable pitting of Al-5wt%Mg microelectrode (diameter 50 μm) after aging at 150 °C for 10 h has been investigated under a constant potential in deaerated 0.6 M NaCl solution (pH 3.5). Current transients (pA size) associated with the dissolution of nanoscale β-phase precipitates have been detected. Taking the cathodic current of H2 evolution inside the pit into account, the average volume determined from a charge associated with individual current transients is about 39% of those measured by TEM. This result implies that the selective dissolution of Mg in β-phase precipitates (Al3Mg2) may occur during the metastable pitting process.

    ABSTRACT: Background/objectives: Dietary patterns represent the combined effects of foods and efficaciously illustrate the impact of diet on health outcomes. This study identified the dietary patterns and determined their relationships with obesity among young Chinese women. Subjects/methods: In 2011, the China Health and Nutrition Survey included 2363 young women aged 18-44 years. Factor analysis of data from three consecutive 24-h dietary recalls identified the dietary patterns. Weight, height and waist circumstance (WC) were measured, and body mass index (BMI) was calculated. General obesity was defined as BMI ⩾28 kg/m(2) and abdominal obesity as WC ⩾85 cm. Results: Four dietary patterns were identified: traditional south; traditional north; snack; and high protein. After adjusting for confounders and energy intake, women in the highest-score quintiles of the traditional south pattern were less likely to have general obesity (odds ratio (OR)=0.48; 95% confidence interval (CI) 0.29-0.78) and abdominal obesity (OR=0.64; 95% CI 0.46-0.90). Subjects in the highest-score quintiles of the traditional north pattern had significantly greater risk of general obesity (OR=2.28; 95% CI 1.38-3.74) and of abdominal obesity (OR=2.32; 95% CI 1.66-3.24). Conclusion: The traditional south pattern of rice as the major staple food with pork and vegetable dishes is associated with lower risk of general and abdominal obesity. The traditional north pattern of high intake of wheat, other cereals and tubers is positively associated with general and abdominal obesity. This provides important information for interventions and policies addressing obesity prevention among young Chinese women.

    ABSTRACT: The effects of the cyclic stress on the metastable pitting corrosion for 304 stainless steel have been investigated under potentiostatic polarization. The results show that cyclic stress with peak stress above yield strength (PSAY) can significantly increase the metastable pitting events and promote the growth of large pits, while those with peak stress below yield strength have no obvious effect. It also reveals that PSAY can decrease the stable pitting potential. These results indicate that cyclic plastic deformation plays more important role on the metastable pitting behaviour than cyclic elastic deformation.

    ABSTRACT: The pitting of Al–Cu–Mg alloy is believed to originate from the local dissolution of S-Al2CuMg particles, and the dissolution activity differs from one particle to another. Nevertheless, the initial site where the dissolution of the S phase preferentially occurs and the cause of the heterogeneity in the electrochemical dissolution activity remain unknown, hindering our understanding of pitting initiation of Al–Cu–Mg alloys. In this work, we have applied in situ ex-environmental transmission electron microscopy and identified a large number of nanosized Al20Cu2Mn3 approximants of the decagonal quasicrystal embedded in the S phase. We find that the S phase with Al20Cu2Mn3 inclusions is more active than those free of the approximants. Such a preference is clarified to result from the decomposition of Al20Cu2Mn3 approximant prior to the dissolution of the S phase. In addition, we also find that the electrochemical behavior of Al20Cu2Mn3 approximants is different. The approximants with multiple twins are more active than those with few planar defects.

    ABSTRACT: In recent years, a large number of mountain tunnels, which have long distance and large buried depth, have been built. But China is a mountainous country with complicated geological conditions. And due to the complicated geological conditions, different kinds of geological disasters often occur during the construction. Therefore, the geological forecast is an important approach to reduce geological disasters effectively. This paper is based on the geological forecast conducted in Jucheng tunnel, Yangquan, Shanxi province. In this paper, a new method of geological forecast is put forward, which is based on the tunnel geological hazards assessment and combine with the stress-strain analysis by using FLAC3D and tunnel seismic tomography (TST). Through risk analysis to identify hazard sections, then select the typical tunnel face of high-risk section and analyze the stress-strain of surrounding rock. Therefore, the stability properties of tunnel section can be obtained. After that, the geological forecast, based on the TST, is conducted on the typical tunnel face. Over all, these new method can forecast the construction geological disasters of different scales of sections (such as the tunnel section or specific tunnel face). Moreover, the new method has obtained the ideal effect in the geological forecast of Jucheng tunnel.

    ABSTRACT: Background/objectives: Several studies have suggested differential health effects in relation to different meat composition in Western population. The purpose of the study was to examine secular trends in meat and seafood consumption patterns among Chinese adults between 1991 and 2011. Subjects/methods: Our longitudinal data are from 21,144 adults aged 18-75 in the China Health and Nutrition Survey, prospective cohort study. We assessed the intakes of meat and subtypes with three 24-h dietary recalls. We conducted multilevel mixed-effect logistic and linear regression models to examine meat consumption dynamics. Results: The proportions of Chinese adults who consumed red meat, poultry and seafood increased from 65.7% in 1991 to 86.1% in 2011, from 7.5 to 20.9% and from 27.4 to 37.8%, respectively. With rapid decrease in meat intakes since 2009, the intakes of total meat, red meat, poultry and seafood among their consumers were 86.7 g/day, 86.4 g/day, 71.0 g/day and 70.3 g/day in 2011, respectively, which were just slightly higher compared with those in 1991. Fatty fresh pork has been predominantly component of total meat overtime, which consituted 54.0% of total meat intake, 80.0% of fresh red meat intake and 98.7% of fatty fresh red meat intake in 2011. Conclusion: Over the past two decades, meat consumption patterns of Chinese adults have been characterized by having a predominant intake of fatty fresh pork, suboptimal intakes of seafood and increased proportion of adults having excessive intakes of red meat and poultry overtime.

    ABSTRACT: The aim of this study was to determine whether monocyte/macrophage β2-AR could act as the therapeutic target of antisympathetic excitation-induced atherosclerotic progression. Cultivated human THP-1 cells were divided into different groups and incubated with isoprenaline, metoprolol, propranolol or β2-AR blocker for 24 h, together with oxidized low-density lipoprotein (ox-LDL). Afterwards, each group was analyzed for C-C chemokine receptor type 2 (CCR2) expression, monocyte chemotactic protein 1 (MCP-1) release into medium and cell migration ability. In the isoprenaline group, CCR2 protein level was increased, as well as the secretion of MCP-1, and cell motility was enhanced, in a concentration-dependent manner. Propranolol and ICI 118,551 significantly reversed the stimulatory effect of isoprenaline on THP-1 cells induced by ox-LDL, but only high concentrations of metoprolol interfered significantly with the action of isoprenaline (P < 0.05). Isoprenaline or a β-AR blocker could mediate through β2-AR, affecting MCP-1 secretion, CCR2 protein expression and cell migration capacity of THP-1 cells. Therefore, monocyte-macrophage β2-AR may act as a target of antisympathetic excitation-induced atherosclerotic progression.

    ABSTRACT: Thermal fatigue failure of metallization interconnect lines subjected to alternating currents (AC) is becoming a severe threat to the long-term reliability of micro/nanodevices with increasing electrical current density/power. Here, thermal fatigue failure behaviors and damage mechanisms of nanocrystalline Au interconnect lines on the silicon glass substrate have been investigated by applying general alternating currents (the pure alternating current coupled with a direct current (DC) component) with different frequencies ranging from 0.05 Hz to 5 kHz. We observed both thermal fatigue damages caused by Joule heating-induced cyclic strain/stress and electromigration (EM) damages caused by the DC component. Besides, the damage formation showed a strong electrically-thermally-mechanically coupled effect and frequency dependence. At lower frequencies, thermal fatigue damages were dominant and the main damage forms were grain coarsening with grain boundary (GB) cracking/voiding and grain thinning. At higher frequencies, EM damages took over and the main damage forms were GB cracking/voiding of smaller grains and hillocks. Furthermore, the healing effect of the reversing current was considered to elucidate damage mechanisms of the nanocrystalline Au lines generated by the general AC. Lastly, a modified model was proposed to predict the lifetime of the nanocrystalline metal interconnect lines, i.e., that was a competing drift velocity-based approach based on the threshold time required for reverse diffusion/healing to occur.

    ABSTRACT: Aim We examined the longitudinal association between red meat (RM) consumption and the risk of abdominal obesity in Chinese adults. Methods and results Our data are from 16,822 adults aged 18 to 75 in the China Health and Nutrition Survey from 1993 to 2011. We assessed RM intake with three 24-hour dietary recalls. We defined abdominal obesity as a waist circumference (WC) ≥ 85 centimeters (cm) for men and ≥ 80 cm for women. Multilevel mixed-effect regression models showed that men experienced WC increases of 0.74 cm (95% confidence interval [CI]: 0.39–1.09) from a higher total intake of fresh RM and 0.59 cm (95% CI: 0.24–0. 95) from a higher intake of fatty fresh RM but 0.14 cm (95% CI: -0.39–0.66) from a higher intake of lean fresh RM in the top versus the bottom quartile when adjusted for potential confounders. In contrast, after additional adjustment for baseline WC, the odds ratios of abdominal obesity in men were attenuated for total fresh RM (1.25 [95% CI: 1.06–1.47]) and fatty fresh RM (1.22 [95% CI: 1.03–1.44]) but were still not affected by lean fresh RM (0.95 [95% CI: 0.75–1.22]). Women also showed a positive association of fatty fresh RM intake with abdominal obesity. Conclusion Greater intake of fatty fresh RM was significantly associated with higher WC (men only) and abdominal obesity risk in Chinese adults. The gender-specific differential association of fatty versus lean fresh RM warrants further study.

    ABSTRACT: Cu-doped ZnO films were prepared by rf magnetron sputtering on sapphire substrate at different atmosphere. Microstructure of these films and Cu occupation sites were investigated using PIXE, SR-XRD and EXAFS. Only 2.9 at.% Cu, no other magnetic impurities (e.g., Fe, Co and Ni) were detected. The ZnO:Cu films possessed the wurtzite ZnO structures and no precipitates (e.g., CuO and Cu2O or Cu cluster) were found. Cu atoms were incorporated into ZnO crystal lattice by occupying Zn atomic sites.

    ABSTRACT: We present the photocurrent spectrum study of a quantum dot (QD) single-photon detector using a reset technique which eliminates the QD's “memory effect.” By applying a proper reset frequency and keeping the detector in linear-response region, the detector's responses to different monochromatic light are resolved which reflects different detection efficiencies. We find the reset photocurrent tails up to 1.3 μm wavelength and near-infrared (∼1100 nm) single-photon sensitivity is demonstrated due to interband transition of electrons in QDs, indicating the device a promising candidate both in quantum information applications and highly sensitive imaging applications operating in relative high temperatures (>80 K).
