Weight under Steel Wheels: Material Stock and Flow Analysis of High‐Speed Rail in China
Authors: Wang Tao , Zhou Jun , Yue Ye , Yang Jie , Hashimoto Seiji 
Published: December 2015

SummaryThe construction of a nation‐wide high‐speed rail (HSR) network has emerged as a hugely expensive and ambitious infrastructure project in China. As of December 2012, some 8,800 kilometers (km) of double‐track HSR lines came into service in the country, accounting for 40% of the total HSR length in the world. The network is expected to expand to 34,000 km or longer in around two decades. As the first HSR system specially built and operated in an economically developing country, it helps integrate the sprawling economy and lift the quality of life of the increasing urban population. China's experiences in HSR are expected to be of value to other countries aiming to adopt bullet train systems, especially those at a similar level of industrialization and urbanization. This work specifically examines material stocks and flows associated with the HSR infrastructure construction in China. A major distinction from the construction of HSR tracks in Europe is that nearly 70% of the HSR tracks in China are laid upon bridges or inside tunnels, which are structures that demand great amounts of raw materials. The entire network, once completed by 2030, will cumulatively require 83 to 137 million tonnes (Mt) of steel and 560 to 920 Mt of cement. This is still a small share of China's use of material resources. Nonetheless, the massive application of the steel‐ and cement‐intensive structures deserves consideration when assessing the environmental performance of HSR over its entire life cycle.

AbstractModifier loci in QPM play a vital role in achieving acceptable degree of kernel hardness and accumulation of lysine and tryptophan. This study was undertaken to characterize a set of diverse QPM inbreds using SSRs linked to endosperm and amino acids modifier loci for their effective utilization in the breeding programme. Significant variation was observed for endosperm modification (25–100% opaqueness), tryptophan (0.056–0.111%) and lysine (0.223–0.444%). Generally, inbreds with soft endosperm possessed more tryptophan and lysine than inbreds with higher vitreousness. SSRs generated 341 alleles with two to seven alleles per locus. The frequency of unique and rare alleles was more for amino acid modifications, compared to endosperm modifications. Phylogenetic analyses grouped the inbreds into three major clusters, and the study identified suitable crosses for accumulation of endosperm and amino acids modifiers. QPM inbreds with desirable modifications identified here would serve as suitable donor for both opaque2 and modifier loci in the marker‐assisted backcross breeding. Further, contrasting inbreds can be used for generating mapping populations to identify new modifier loci underlying both endosperm and amino acids modifications.

AbstractSeedling traits are important for development, flower bud differentiation, fruit production and fruit quality of cucumber (Cucumis sativus L.). In this study, 160 recombinant inbred lines (RILs), derived from crossing wild cucumber inbred line PI 183967 (C. sativus var. hardwickii) with ‘931’ northern China cultivated cucumber inbred line 931, were employed to identify quantitative trait loci (QTLs) of cotyledon length (Cl), cotyledon width (Cw), hypocotyl length (Hl), first true leaf length (Fll), first true leaf width (Flw), aboveground fresh biomass (Afb) and aboveground dry biomass (Adb) at seedling stage. A genetic map including 307 SSR markers was developed which spanned 993.3 cM, with an average genetic distance of 3.23 cM between adjacent markers. 36 QTLs associated with the seven traits were detected on chromosomes 1, 2, 3, 5 and 6 in four environments (spring and autumn of 2012 and 2013), explaining 6.1 to 23.6% of the observed phenotypic variations. Among the 36 QTLs, 21 were responsible for more than 10% of observed phenotypic variations. We obtained 2, 2, 1 and 3 QTL loci for the traits of Fll, Flw, Afw and Adw, respectively. In addition, genes in the genetic region spanned by SSR15321‐SSR07711 on chr. 5 may contribute to Flw, Afw and Adw.
Wheat streak mosaic virus resistance in eight wheat germplasm lines
Authors: Zhang Xinzhong , Bai Guihua , Xu Rugen , Zhang Guorong 
Published: December 2015

AbstractWheat streak mosaic virus (WSMV) is a destructive pathogen in wheat (Triticum aestivum L.). Host resistance is the most effective way to control this virus. To date, Wsm2 is the only wheat resistance gene that is genetically mapped. The objective of this study was to identify germplasm lines that might carry resistance genes different from Wsm2. Eight newly reported resistant germplasm lines were examined by allelic tests. To validate the allelic test results, five of them were further analysed for the inheritance of WSMV resistance. A Wsm2‐linked marker was also genotyped on populations developed for the inheritance study. Our results suggested that the WSMV resistance in lines CItr9358, PI225288, PI243652, PI245439, PI245526 and PI478095 was controlled by either Wsm2 or a gene very closely linked to Wsm2. The resistance in PI243753 and PI321730, however, is likely controlled by a gene different from, but linked to Wsm2. The resistance in PI321730 might also involve some minor genes. This study provided useful information for breeders to select appropriate resistant lines to improve WSMV resistance in wheat.

Published: December 2015

AbstractEuropean silage maize is cultivated for animal feed and biogas production. We evaluated 210 factorial crosses of elite dent and flint lines in multilocation trials for agronomic and quality traits together with biomass and shoot concentrations of 10 elements in juvenile plants. Significant genotypic variances, mainly due to general combining ability variance of the dent lines, and high heritabilities were observed for dry matter yield (DMY) and quality traits. DMY was not correlated with quality traits, but methane fermentation yield (MFY) and metabolizable energy content (MEC) showed significant correlations with starch and fibre content. Concentrations of elements N,P,S,K were positively correlated with each other but only in few cases correlated with DMY and quality traits. Parent lines with contrasting P concentrations differed in root morphology traits. Results support DMY as primary trait for selection of silage maize hybrids, but MFY is of negligible importance in breeding for biogas contrary to MEC for animal feed. Neither biomass nor elemental composition of juvenile plants were of predictive value for final DMY or quality traits.

Published: December 2015

AbstractBackgroundOnly a handful of studies have investigated children with functional dyspepsia (FD) and irritable bowel syndrome (IBS) classified according to the Rome III criteria, and limited information is available on the lifestyle of affected patients.MethodsWe conducted an Internet questionnaire survey of 2060 parents among the general public in Japan who lived with their children aged 10–15, who were screened for FD and IBS.ResultsThe prevalence of FD and IBS was 2.8% and 6.1%, respectively, and 1.4% of the subjects met the criteria for both FD and IBS. The lifestyles of 155 subjects who met the criteria for FD, IBS, or both were compared with those of 1745 control subjects. In comparison with the controls, a significantly higher percentage of subjects with FD, IBS, or both thought that their sleep was insufficient, ate meals irregularly, were susceptible to stress and to dizziness on standing, had difficulty in getting out of bed or felt sluggish in the morning, had a tendency to faint when standing, and had migraine/chronic headache.ConclusionsChildren with FD and IBS are susceptible to stress, have impaired sleep and eating habits, and have more frequent symptoms of comorbid orthostatic dysregulation and headache.

Published: December 2015

AbstractWe report two CMV naïve children who received deceased donor renal transplants from a CMV IgG‐negative single donor. CMV IgG in both recipients and the donor were negative immediately prior to transplant. Both recipients had early recurrences of their original disease in their transplants, requiring multiple sessions of plasmapheresis. All blood products used were leukoreduced or CMV seronegative. A few days post‐transplant, both recipients developed significant positive CMV viremia. Both required initiation of oral valganciclovir. Case 1 responded to oral valganciclovir only while the case 2 had a delayed response to it and hence required intravenous ganciclovir with good response. When checked retrospectively, CMV IgM in the donor was positive along with positive CMV DNA PCR from the white cells. Here we describe a very unusual scenario of CMV transmission in two pediatric renal transplant recipients from a single donor during the CMV window period.
Rural Disadvantage and Malaria in Less‐Developed Nations: A Cross‐National Investigation of a Neglected Disease
Authors: Noble Mark D. , Austin Kelly F. 
Published: December 2015

AbstractAlthough often forgotten among people in affluent nations, malaria represents a leading global health concern in poor, rural countries. Malaria is traditionally thought of as a rural disease, given the close proximity of rural households to mosquito disease vectors. However, more insight is needed to investigate the larger social, economic, and environmental conditions that perhaps interact with rurality to explain why some nations continue to have high levels of prevalence of this preventable and eradicable parasitic infection. We employ structural equation modeling to efficiently test for both direct and indirect effects of rurality. The results demonstrate that rurality works in important indirect ways; although rurality has indirect links to malaria through export agriculture, health spending, and sociohealth resources, careful decomposition of the indirect effects illustrates that the indirect effects through heath spending and sociohealth resources are most important. Overall, the findings suggest that rural vulnerabilities to malaria are not inherent and can be largely addressed by increasing public health provisions among rural populations.

Published: December 2015

Athletes’ sport experiences are often influenced by the interpersonal styles of communication used by their coaches. Research on personality antecedents of such styles is scarce. We examined the link between a well‐researched personality trait, namely narcissism, and two types of coaching interpersonal style, namely autonomy‐supportive and controlling styles. We also tested the mediating roles of dominance and empathic concern in explaining the relations between narcissism and the two coaching interpersonal styles. United Kingdom‐based coaches (N = 211) from various sports completed a multi‐section questionnaire assessing the study variables. Regression analyses revealed a positive direct relation between narcissism and controlling coach behaviors. Furthermore, empathy (but not dominance) mediated the positive and negative indirect effects of narcissism on controlling and autonomy‐supported interpersonal styles, respectively. We discuss these findings in terms of their implications for coaching and the quality of athletes’ sport experiences.
The Effect of Primary School Absence and Closure on Inward and Outward Flows of Families

Published: December 2015

AbstractDue to ageing and depopulation, the continued existence of many primary schools in villages in rural North‐Netherlands is threatened. It is believed that villages without a primary school will no longer be attractive to families with children, which could strengthen the process of population decline. This research examines to what extent the absence and closure of a primary school in a village influence the inward and outward flows of families with children in rural villages. We used population register data to acquire the flows at village level for the period 1996 to 2011. Data on primary schools were provided by the Dutch Ministry of Education, Culture and Science. Linear regression analyses of relative inward and outward flows show that villages without a primary school, and villages that have experienced the closure of a primary school, have similar influx, but larger outward flows of families with children compared with villages with a primary school.
Sensible Energy Accounting with Abstract Metering for Multicore Systems

Published: December 2015

Chip multicore processors (CMPs) are the preferred processing platform across different domains such as data centers, real-time systems, and mobile devices. In all those domains, energy is arguably the most expensive resource in a computing system. Accurately quantifying energy usage in a multicore environment presents a challenge as well as an opportunity for optimization. Standard metering approaches are not capable of delivering consistent results with shared resources, since the same task with the same inputs may have different energy consumption based on the mix of co-running tasks. However, it is reasonable for data-center operators to charge on the basis of estimated energy usage rather than time since energy is more correlated with their actual cost.
This article introduces the concept of Sensible Energy Accounting (SEA). For a task running in a multicore system, SEA accurately estimates the energy the task would have consumed running in isolation with a given fraction of the CMP shared resources. We explain the potential benefits of SEA in different domains and describe two hardware techniques to implement it for a shared last-level cache and on-core resources in SMT processors. Moreover, with SEA, an energy-aware scheduler can find a highly efficient on-chip resource assignment, reducing by up to 39% the total processor energy for a 4-core system.
Neural Network Spectral Robustness under Perturbations of the Underlying Graph
Authors: Rădulescu Anca 
Published: December 2015

Recent studies have been using graph-theoretical approaches to model complex networks (such as social, infrastructural, or biological networks) and how their hardwired circuitry relates to their dynamic evolution in time. Understanding how configuration reflects on the coupled behavior in a system of dynamic nodes can be of great importance, for example, in the context of how the brain connectome is affecting brain function. However, the effect of connectivity patterns on network dynamics is far from being fully understood. We study the connections between edge configuration and dynamics in a simple oriented network composed of two interconnected cliques (representative of brain feedback regulatory circuitry). In this article our main goal is to study the spectra of the graph adjacency and Laplacian matrices, with a focus on three aspects in particular: (1) the sensitivity and robustness of the spectrum in response to varying the intra- and intermodular edge density, (2) the effects on the spectrum of perturbing the edge configuration while keeping the densities fixed, and (3) the effects of increasing the network size. We study some tractable aspects analytically, then simulate more general results numerically, thus aiming to motivate and explain our further work on the effect of these patterns on the network temporal dynamics and phase transitions. We discuss the implications of such results to modeling brain connectomics. We suggest potential applications to understanding synaptic restructuring in learning networks and the effects of network configuration on function of regulatory neural circuits.

Published: December 2015

The present work re-evaluates the Mandevilla subsessilis complex (Apocynaceae: Apocynoideae). Based on morphological analysis, including UPGMA, we recognize two separate species, respectively distributed primarily west and east of the Isthmus of Tehuantepec: M. platydactyla (with M. mollis as a synonym) and M. subsessilis. Mandevilla platydactyla is found from the Sierras de Chiapas to Nicaragua, whereas M. subsessilis is endemic to Mexico, particularly the Sierra Madre del Sur.

Objective To evaluate the efficacy and safety of intrathecal morphine (ITM) for postoperative pain control in patients with renal cell carcinoma undergoing open nephrectomy. Methods Forty-five patients scheduled for open nephrectomy were randomised to receive 300 µg ITM and intravenous patient-controlled analgesia (IV-PCA) ( n = 22) or IV-PCA alone ( n = 23) for postoperative analgesia. The numeric pain score (NPS), postoperative IV-PCA requirements and opioid-related complications including nausea, vomiting, dizziness, headache, and pruritus were compared between groups. Results NPS was significantly lower in the ITM group up to 24 h postoperatively. Upon coughing, NPS at 24 h postoperatively was 50 (interquartile range (IQR) 30–60) in the ITM group and 60 (45–70) in the IV-PCA group. Cumulative morphine consumption at 72 h postoperatively was significantly lower in the ITM group compared with the IV-PCA group (20 (9–33) mg vs. 31 (21–49) mg, respectively). Opioid-related complications were similar in both groups with the exception of pruritus (ITM, 77% vs. IV-PCA, 26%). Conclusions ITM was associated with greater analgesia without serious complications in patients undergoing open nephrectomy.

Published: December 2015

Background: Morphine is the first-choice drug for moderate-to-severe cancer pain, nevertheless, some patients do not achieve adequate pain relief or exhibit intolerable side effects. The purpose of this study was to establish whether the analgesic effect of morphine improves in patients with cancer when administered in combination with magnesium. Methods: Randomized double-blind study was conducted with 40 patients older than 18 years with cancer pain using morphine. Group 1 (G1) patients were given magnesium sulfate (65 mg elemental magnesium) twice per day by the oral route. Group 2 (G2) patients were given placebo twice per day. All the patients were administered morphine as needed. They were also given acetaminophen at 2 to 3 g/d. Adjuvants could be used when indicated. The following variables were assessed: pain intensity on a numeric scale at baseline and at weeks 1, 2, 3, and 4; functional performance and quality of life at baseline and week 4; and dose of morphine used. Results: No difference was found between the groups as to pain intensity, dose of morphine used, functional performance, quality of life, or side effects. The average daily dose of morphine increased gradually, being significant in G2. Conclusions: The use of morphine combined with elemental magnesium at a dose of 65 mg twice per day by patients with cancer did not induce a better analgesic effect, did not improve their functional performance or quality of life, and did not reduce the occurrence of side effects. The dose of morphine increased significantly in G2.

Published: December 2015

Objective To determine the 50 most cited articles in orthopedic cartilage surgery and their characteristics. Design A systematic review of the Science Citation Index Expanded was performed for articles related to cartilage surgery published in the 66 journals under the category “Orthopedics.” The 50 most cited articles were determined, and the following characteristics were analyzed for each article: authors, journal and year of publication, number of citations, geographic origin, article type (basic science or clinical), article subtype by study design, and level of evidence. Citation density (total number of citations/years since publication) was also computed. Results The 50 most cited articles ranged from 989 to 172 citations, with citation density ranging from 71.5 to 4.1. The publication years spanned from 1968 to 2008, with the 2000s accounting for half (25) of the articles and the highest mean citation density (14.6). The 50 most cited articles were published in 11 journals. The majority of the articles (29) were clinical, with level IV representing the most common level of evidence (10). The remaining basic science articles were most commonly animal in vivo studies (14). Stronger level of evidence was correlated with overall number of citations ( P = 0.044), citation density ( P < 0.001), and year of publication ( P = 0.003). Conclusions Articles with stronger levels of evidence are more highly cited, with an increasing trend as evidence-based practice has been emphasized. This article list provides clinicians, researchers, and trainees with a group of “citation classics” in orthopedic cartilage surgery.
