Right translated AES gray S‐boxes
Authors: Khan Mubashar , Azam Naveed Ahmed 
Published: September 2014

AbstractThis article deals with an algorithm for the generation of impregnable substitution boxes (S‐box). The proposed scheme involves the application of right translation and Gray codes over the original Advanced Encryption Standard (AES) S‐box. Regular representation of Galois field GF(28) is used to produce the translational effect in the AES S‐box. The translated AES S‐box is then subjected to Gray codes for the enhancement in their algebraic complexity. The proposed scheme results 256 different cryptographically strong S‐boxes. Several tests such as non‐linearity, bit independence, strict avalanche, linear approximation and differential approximation, algebraic complexity, correlation and histogram are implemented on every newly generated S‐box to analyze their resistance against computational attacks. Furthermore, the newly generated S‐boxes are compared with the existing well‐known S‐boxes. The simulation results indicate that the resistance of proposed S‐boxes against computational attacks including linear, interpolation, differential and algebraic attacks approaches to the optimal values.

Improved pattern sequence‐based forecasting method for electricity load
Authors: Jin Cheng Hao , Pok Gouchol , Park Hyun‐Woo , Ryu Keun Ho 
Published: September 2014

Recently, a pattern sequence‐based forecasting (PSF) algorithm was proposed for day‐ahead electricity time series. PSF consists of two steps: clustering and prediction. However, it has the following limitations: In the clustering step, it is computationally expensive to determine the optimal number of clusters with majority votes. In the prediction step, it is quite complex to search for the matched pattern sequence with the optimal window length, and averaging all the samples immediately after the matched sequence can increase the forecasting accuracy especially when the day under examination is a working day.In this paper, we propose a time‐series forecasting method for electricity load by addressing the limitations in PSF. The proposed method is evaluated on electricity load datasets, and the experimental results show that the proposed method can improve the forecasting accuracy of PSF. © 2014 Institute of Electrical Engineers of Japan.

Using ungulate biomass to estimate abundance of wolves in British Columbia
Authors: Kuzyk Gerald W. , Hatter Ian W. 
Published: September 2014

ABSTRACTManagement of wolves (Canis lupus) in British Columbia, as with most other Canadian provinces, is conducted on a regional scale (38,557–252,776 km2), yet there is no standardized, cost‐effective methodology for providing reliable estimates of wolf abundance at this scale. Therefore, we used periodic estimates of ungulate abundance and incorporated them into an ungulate biomass regression model to estimate wolf abundance on a regional and provincial (900,402 km2) scale over a 12‐year period (2000–2011). In 2011, the provincial estimate was 8,688 (95% CI = 5898–11,760) wolves (7–13 wolves/1,000 km2), while regional wolf abundance estimates ranged from 149 (95% CI = 100–205) to 2,693 (95% CI = 1,818–3,608) with differences related to regional scale (km2) rather than wolf densities (4–15 wolves/1,000 km2). We suggest the ungulate biomass regression model is useful to estimate the abundance of wolves for management purposes when precise estimates are not required and wolf populations are not heavily exploited or recovering. © 2014 The Wildlife Society.

Abstract

Purpose
There is little research-based documentation on the services provided by drug information centres (DICs). The aim of this multi-centre study was to explore for the first time the factors associated with time consumption when answering drug-related queries at eight different but comparable DICs.

Methods
During an 8-week period, staff members at eight Scandinavian DICs recorded the number of minutes during which they responded to queries. Mixed model linear regression analyses were used to explore the factors associated with time consumption when answering queries.

Results
The mean time consumption per query was 178 min (range 4–2540 min). The mean time consumed per query increased by 28 (95 % confidence interval (CI) 23 to 33, p < 0.001) min higher for queries for which there was a lack of documentation and 139 (95 % CI 74 to 203, p < 0.001) min higher when conflicting information was present in the literature. Staff members with less than 1 year of experience consumed a mean of 91 more minutes (95 % CI 32 to 150, p = 0.003) per query than staff members with more than 2 years of experience.

Conclusions
This study demonstrates the large variation in time consumed answering queries posed to Scandinavian DICs. The results highlight the need for highly competent staff members and easy access to drug information sources. Further studies are required to explore the association between time consumption and response quality.
Molecular engineering of secretory machinery components for high-level secretion of proteins in Bacillus species
Authors: Kang Zhen , Yang Sen , Du Guocheng , Chen Jian 
Published: September 2014

Abstract
Secretory expression of valuable enzymes by Bacillus subtilis and its related species has attracted intensive work over the past three decades. Although many proteins have been expressed and secreted, the titers of some recombinant enzymes are still low to meet the needs of practical applications. Signal peptides that located at the N-terminal of nascent peptide chains play crucial roles in the secretion process. In this mini-review, we summarize recent progress in secretory expression of recombinant proteins in Bacillus species. In particular, we highlighted and discussed the advances in molecular engineering of secretory machinery components, construction of signal sequence libraries and identification of functional signal peptides with high-throughput screening strategy. The prospects of future research are also proposed.

AbstractFamilies play an important role in the lives of individuals with mental illness. Coping with the strain of shifting roles and multiple challenges of caregiving can have a huge impact. Limited information exists regarding race‐related differences in families’ caregiving experiences, their abilities to cope with the mental illness of a loved one, or their interactions with mental health service systems. This study examined race‐related differences in the experiences of adults seeking to participate in the National Alliance on Mental Illness Family‐to‐Family Education Program due to mental illness of a loved one. Participants were 293 White and 107 African American family members who completed measures of problem‐ and emotion‐focused coping, knowledge about mental illness, subjective illness burden, psychological distress, and family functioning. Multiple regression analyses were used to determine race‐related differences. African American caregivers reported higher levels of negative caregiving experiences, less knowledge of mental illness, and higher levels of both problem‐solving coping and emotion‐focused coping, than White caregivers. Mental health programs serving African American families should consider targeting specific strategies to address caregiving challenges, support their use of existing coping mechanisms and support networks, and increase their knowledge of mental illness.

SummaryBackground In the international, phase III, randomized, double-blind CORRECT trial, regorafenib significantly prolonged overall survival (OS) versus placebo in patients with metastatic colorectal cancer (mCRC) that had progressed on all standard therapies. This post hoc analysis evaluated the efficacy and safety of regorafenib in Japanese and non-Japanese subpopulations in the CORRECT trial. Methods Patients were randomized 2 : 1 to regorafenib 160 mg once daily or placebo for weeks 1–3 of each 4-week cycle. The primary endpoint was OS. Outcomes were assessed using descriptive statistics. Results One hundred Japanese and 660 non-Japanese patients were randomized to regorafenib (n = 67 and n = 438) or placebo (n = 33 and n = 222). Regorafenib had a consistent OS benefit in the Japanese and non-Japanese subpopulations, with hazard ratios of 0.81 (95 % confidence interval [CI] 0.43–1.51) and 0.77 (95 % CI 0.62–0.94), respectively. Regorafenib-associated hand–foot skin reaction, hypertension, proteinuria, thrombocytopenia, and lipase elevations occurred more frequently in the Japanese subpopulation than in the non-Japanese subpopulation, but were generally manageable. Conclusion Regorafenib appears to have comparable efficacy in Japanese and non-Japanese subpopulations, with a manageable adverse-event profile, suggesting that this agent could potentially become a standard of care in patients with mCRC.

Published: September 2014

Abstract
The Magnetospheric Multiscale (MMS) mission and operations are designed to provide the maximum reconnection science. The mission phases are chosen to investigate reconnection at the dayside magnetopause and in the magnetotail. At the dayside, the MMS orbits are chosen to maximize encounters with the magnetopause in regions where the probability of encountering the reconnection diffusion region is high. In the magnetotail, the orbits are chosen to maximize encounters with the neutral sheet, where reconnection is known to occur episodically. Although this targeting is limited by engineering constraints such as total available fuel, high science return orbits exist for launch dates over most of the year. The tetrahedral spacecraft formation has variable spacing to determine the optimum separations for the reconnection regions at the magnetopause and in the magnetotail. In the specific science regions of interest, the spacecraft are operated in a fast survey mode with continuous acquisition of burst mode data. Later, burst mode triggers and a ground-based scientist in the loop are used to determine the highest quality data to downlink for analysis. This operations scheme maximizes the science return for the mission.
Cumulative Structural Disadvantage and Racial Health Disparities: The Pathways of Childhood Socioeconomic Influence
Authors: Pais Jeremy 
Published: September 2014

Abstract
Cumulative structural disadvantage theory posits two major sources of endogenous selection in shaping racial health disparities: a race-based version of the theory anticipates a racially distinct selection process, whereas a social class-based version anticipates a racially similar process. To operationalize cumulative structural disadvantage, this study uses data from the 1979 National Longitudinal Survey of Youth in a Latent Class Analysis that demographically profiles health impairment trajectories. This analysis is used to examine the nature of selection as it relates to racial differences in the development of health impairments that are significant enough to hinder one’s ability to work. The results provide no direct support for the race-based version of cumulative structural disadvantage theory. Instead, two key findings support the social class–based version of cumulative disadvantage theory. First, the functional form of the different health trajectories are invariant for whites and blacks, suggesting more racial similarly in the developmental process than anticipated by the race-based version of the theory. The extent of the racial disparity in the prevalences across the health impairment trajectories is, however, significant and noteworthy: nearly one-third of blacks (28 %) in the United States experience some form of impairment during their prime working years compared with 18.8 % of whites. Second, racial differences in childhood background mediate this racial health disparity through the indirect pathway of occupational attainment and through the direct pathway of early-life exposure to health-adverse environments. Thus, the selection of individuals into different health trajectories, based largely on childhood socioeconomic background, helps explain racial disparities in the development of health impairments.

Published: September 2014

AbstractThe process of lignite desulphurization via its treatment by an oxidant (air or air–steam mixture) has been studied. The research objective was useful determination of steam application in oxidative lignite desulphurization. It has been proved that the water steam should be included in the oxidant composition to increase the hydrogen sulphide and combustible constituent content in the gases obtained during the processes under research. The impact of factors which affect the reactions between solid (in our case – lignite) and gaseous reagent (oxidant, i.e. air and or air–steam mixture) upon the research process has been investigated, if these reactions occur in the kinetic area. Such factors are linear rate of oxidant movement and coal grain size. The values of oxidant movement linear rate and coal grain size, which the reaction transfer from pyrite sulphur and organic content of lignite from diffusion into kinetic area occurs by, have been determined. Under these “transfer” conditions, the values of coefficients of oxidant mass transfer (β, m/s) as well as Sherwood criteria and boiling layer differences have been calculated.

Authors: Li Haibin , Yu Yu , Han Minfang , Lei Ze 
Published: September 2014

AbstractThe authors proposed an integrated gasification fuel cell zero-emission system. The coal char gasification is discussed using high temperature and concentration of CO2 produced by solid oxide fuel cells and oxy-fuel combustion. The gasification is simulated by Aspen plus based on Gibbs free energy minimization method. Gasification model of pulverized coal char is computed and analyzed. Effects of gas flow rate, pressure, preheating temperature, heat losses on syngas composition, reaction temperature, lower heating value and carbon conversion are studied. Results and parameters are determined as following. The optimum O2 flow rate is 20 kg/h. The reaction temperature decreases from 1645 to 1329 °C when the CO2 flow rate increases from 0 to 5 kg/h, the CO2 flow rate should be operated reasonably; lower heating value reduces and reaction temperature increases as the pressure increases; compared to the CO2 preheating, O2 preheating has greater influence on reaction temperature and lower heating value.

Authors: Wang Jinyi , Xu Shisen 
Published: September 2014

AbstractCO2 capture is an important carbon management route to mitigate the greenhouse gas emission in power sector. In recent years, China Huaneng Group (CHNG) has paid more attention on CO2 capture technology development and launched a series of R&D and demonstration projects. In the area of pre-combustion CO2 capture technology, GreenGen project initiated by CHNG is the first integrated gasification combined cycle (IGCC) power plant in China. Located in Tianjin, GreenGen aims at the development, demonstration and promotion of a near-zero emissions power plant. An IGCC plant of 250 MW has successfully passed full-scale trial operation. In the next phase, a pre-combustion CO2 capture unit will be integrated into the system. Pre-combustion process based on coal chemical process has been developed with lower costs successfully. Regarding to post-combustion CO2 capture (PCC), in 2008, CHNG built a 3,000 tpa CO2 capture plant, which was the first CO2 capture demonstration plant in China. In 2009, CHNG launched a PCC project in Shanghai with a capture capacity of 120,000 tpa CO2. Recently, Huaneng Clean Energy Research Institute (CERI) and Powerspan formed a joint venture, Huaneng-CERI-Powerspan (HCP). HCP has completed the technology qualification program to supply carbon capture technology for the CO2 capture Mongstad project. Besides these activities mentioned above, feasibility studies and system design for large scale PCC system, have been undertaken by CERI and its partners from Australia, US and Europe.
Electrochemical performance and stability of Sr-doped LaMnO3-infiltrated yttria stabilized zirconia oxygen electrode for reversible solid oxide fuel cells
Authors: Fan Hui , Han Minfang 
Published: September 2014

AbstractPorous Sr-doped lanthanum manganite–yttria stabilized zirconia (LSM–YSZ) oxygen electrode is prepared by an infiltration process for a reversible solid oxide fuel cell (RSOFC). X-ray diffraction and SEM analysis display that perovskite phase LSM submicro particles are evenly distributed in the porous YSZ matrix. Polarization curves and electrochemical impedance spectra are conducted for the RSOFC at 800 and 850 °C under both SOFC and SOEC modes. At 850 °C, the single cell has the maximum power density of ~726 mW/cm2 under SOFC mode, and electrolysis voltage of 1.35 V at 1 A/cm2 under SOEC mode. Fuel cell/water electrolysis cycle shows the cell has good performance stability during 6 cycles, which exhibits the LSM–YSZ oxygen electrode has high electrochemical performance and good stability. The results suggest that network-like LSM–YSZ electrode made by infiltration process could be a promising oxygen electrode for high temperature RSOFCs.
Lean manufacturing and firm performance: The incremental contribution of lean management accounting practices
Authors: Fullerton Rosemary R. , Kennedy Frances A. , Widener Sally K. 
Published: September 2014

AbstractManufacturing firms operating in rapidly changing and highly competitive markets have embraced the continuous process improvement mindset. They have worked to improve quality, flexibility, and customer response time using the principles ofLean thinking. To reach its potential, lean must be adopted as a holistic business strategy, rather than an activity isolated in operations. The lean enterprise calls for the integration of lean practices across operations and other business functions. As a critical component for achieving financial control, management accounting practices (MAP) need to be adjusted to meet the demands and objectives of lean organizations. Our aim is to help both researchers and practitioners better understand how lean MAP can support operations personnel with their internal decision making, and operations executives and business leaders in their objective of increasing lean operations performance as part of a holistic lean enterprise strategy. We use survey data from 244 U.S. manufacturing firms to construct a structural equation model. We document that the extent of lean manufacturing implementation is associated with the use of lean MAP, and further that the lean MAP are related in a systematic way: simplified and strategically aligned MAP positively influences the use of value stream costing, which in turn positively influences the use of visual performance measures. We also find that the extent of lean manufacturing practices is directly related to operations performance. More importantly, lean manufacturing practices also indirectly affect operations performancethroughlean MAP. These findings are consistent with the notion that lean thinking is a holistic business strategy. In order to derive the greatest impact on performance, our results indicate that operations management cannot operate in a vacuum. Instead, operations and accounting personnel must partner with each other to ensure that lean MAP are strategically integrated into the lean culture. In sum, lean MAP provide essential financial control that integrates with and supports operations to achieve desired benefits.

AbstractFor a better understanding of the population structure and dispersal rates ofSogatella furcifera, we developed 21 novel polymorphic expressed sequence tags (EST) derived microsatellites, which were successfully amplified in four multiplex polymerase chain reaction sets. These new microsatellites were firstly assessed in 20 individuals sampled from Wenshan in China. The results showed that all 21 loci were highly polymorphic; the number of alleles ranged from 3 to 9, with an average of 4.8 alleles per locus. The observed and expected heterozygosity ranged from 0.200 to 0.900 and from 0.184 to 0.799, respectively. Nineteen of the 21 microsatellites without null allele, were subsequently used for population genetic structure analyses of fiveS. furciferapopulations sampled in south region of China (sites up to 1314 kilometers apart). The observed and expected heterozygosity for each population ranged from 0.436 to 0.494 and from 0.454 to 0.482, respectively. The level of population differentiation was very low, with an average pairwiseFSTof 0.002. Bayesian cluster analysis result suggested that the fiveS. furciferapopulations formed one genetic cluster. Discriminant analysis of principle components detected three genetic clusters. The spread of the three clusters across the five populations explained the lack of population differentiation and the Bayesian cluster result. All the results indicated that long-distance migration of this pest allowed genetic mixing between populations from remote geographical origins. These new microsatellites will be powerful tools for population genetics studies ofS. furcifera.
