A novel ammonia-oxidizing archaeon from wastewater treatment plant: Its enrichment, physiological and genomic characteristics
Authors: Li Yuyang , Ding Kun , Wen Xianghua , Zhang Bing , Shen Bo , Yang Yunfeng 
Published: March 2016

AbstractAmmonia-oxidizing archaea (AOA) are recently found to participate in the ammonia removal processes in wastewater treatment plants (WWTPs), similar to their bacterial counterparts. However, due to lack of cultivated AOA strains from WWTPs, their functions and contributions in these systems remain unclear. Here we report a novel AOA strain SAT1 enriched from activated sludge, with its physiological and genomic characteristics investigated. The maximal 16S rRNA gene similarity between SAT1 and other reported AOA strain is 96% (with “Ca. Nitrosotenuis chungbukensis”), and it is affiliated with Wastewater Cluster B (WWC-B) based on amoA gene phylogeny, a cluster within group I.1a and specific for activated sludge. Our strain is autotrophic, mesophilic (25 °C–33 °C) and neutrophilic (pH 5.0–7.0). Its genome size is 1.62 Mb, with a large fragment inversion (accounted for 68% genomic size) inside. The strain could not utilize urea due to truncation of the urea transporter gene. The lack of the pathways to synthesize usual compatible solutes makes it intolerant to high salinity (>0.03%), but could adapt to low salinity (0.005%) environments. This adaptation, together with possibly enhanced cell-biofilm attachment ability, makes it suitable for WWTPs environment. We propose the name “Candidatus Nitrosotenuis cloacae” for the strain SAT1.

Published: March 2016

AbstractHybrid visceral-renal debranching procedures with endovascular repair have been proposed as an appealing technique to treat conventional thoracoabdominal aortic aneurysm (TAAA). This approach, however, still remained controversial because of the non-physiological blood flow direction of its retrograde visceral revascularization (RVR) which is generally constructed from the aortic bifurcation or common iliac artery. The current study carried out the numerical simulation to investigate the effect of RVR on the hemodynamics of abdominal aorta. The results indicated that the inflow sites for the RVR have great impact on the hemodynamic performance. When RVR was from the distal aorta, the perfusion to visceral organs were adequate but the flow flux to the iliac artery significantly decreased and a complex disturbed flow field developed at the distal aorta, which endangered the aorta at high risk of aneurysm development. When RVR was from the right iliac artery, the abdominal aorta was not troubled with low WSS or disturbed flow, but the inadequate perfusion to the visceral organs reached up to 40% and low WSS and flow velocity predominated appeared at the right iliac artery and the grafts, which may result in the stenosis in grafts and aneurysm growth on the host iliac artery.

AbstractProgranulin (PGRN) is a secreted growth factor associated with embryo development, tissue repair and inflammation. In a previous study, we showed that adipose-derived stem cell-conditioned medium (ASC-CM) is rich in PGRN. In the present study, we investigated whether PGRN is associated with retinal regeneration in the mammalian retina. We evaluated the effect of ASC-CM using the N-methyl-N-nitrosourea-induced retinal damage model in mice. ASC-CM promoted the differentiation of photoreceptor cells following retinal damage. PGRN increased the number of BrdU+ cells in the outer nuclear layer following retinal damage some of which were Rx (retinal precursor cell marker) positive. PGRN also increased the number of rhodopsin+ photoreceptor cells in primary retinal cell cultures. SU11274, a hepatocyte growth factor (HGF) receptor inhibitor, attenuated the increase. These findings suggest that PGRN may affect the differentiation of retinal precursor cells to photoreceptor cells through the HGF receptor signaling pathway.

Published: March 2016

AbstractCatalytic oxidation of carbon monoxide (CO) is of great importance in many different fields of industry. Until now it still remains challenging to use non-noble metal based catalysts to oxidize CO at low temperature. Herein, we report a new class of nanoporous, uniform and transition metal-doped cerium (IV) oxide (ceria, CeO2) microsphere for CO oxidation catalysis. The porous and uniform microsphere is generated by sacrificed polymer template. Transition-metals, like Cu, Co, Ni, Mn and Fe, were doped into CeO2 microspheres. The combination of hierarchical structure and metal doping afford superior catalytic activities of the doped ceria microspheres, which could pave a new way to advanced non-precious metal based catalysts for CO oxidation.
Two mutations G335D and Q343R within the amyloidogenic core region of TDP-43 influence its aggregation and inclusion formation

Published: March 2016

AbstractTDP-43 is a DNA/RNA binding protein associated with TDP-43 proteinopathies. Many mutations have been identified in the flexible C-terminal region, which is implicated in the disease pathology. We investigated four point mutations in the amyloidogenic core region (residues 311–360) of TDP-43 by biochemical and spectroscopic methods. We found that the G335D mutation enhances the aggregation and inclusion formation of TDP-43 and this mutant in TDP-35 (the C-terminal fragment of 35 kDa) exaggerates the antagonist effect on RNA processing by endogenous TDP-43; whereas Q343R gives an opposite effect. As a comparison, M337V and Q331K have very little impact on the aggregation and inclusion formation of TDP-43 or TDP-35. NMR structural analysis showed that the G335D mutant in the core region forms a loop linker between the two α-helices and promotes α-to-β transition, but Q343R loses the second helix and consequently the structural transformation. Thus, the propensity of structural transformation in the amyloidogenic core of TDP-43 determines its aggregation and inclusion formation. This study may provide a molecular mechanism of the TDP-43 proteinopathies caused by genetic mutations.

Published: March 2016

A 160 dB high dynamic range pixel architecture with charge compensation technique for CMOS image sensor (CIS) is presented. Employing a built‐in charge compensation photodiode, the operation mode of the proposed pixel can switch between linear mode and logarithmic mode automatically according to the incident light intensity. The measured result shows a CIS with the proposed pixel architecture has a dynamic range up to 160.9 dB with an output swing of 1.9 V. Moreover, this scheme does not require complex control circuits and complicated timing sequence.
Comprehensive mutagenesis of thefimSpromoter regulatory switch reveals novel regulation of type 1 pili in uropathogenicEscherichia coli
Authors: Zhang Huibin , Susanto Teodorus T. , Wan Yue , Chen Swaine L. 
Published: March 2016

SignificanceUrinary tract infections are common infections caused mostly by uropathogenicEscherichia coli(UPEC). Type 1 pili (T1P) are important UPEC virulence factors and thus are attractive therapeutic targets. T1P expression is highly regulated and phase variable, resulting in piliated and nonpiliated bacteria in an otherwise clonal population. Regulation converges at the invertiblefimS(fimswitch) regulatory sequence. We performed the first (to our knowledge) comprehensive analysis offimSmutations affecting phase variation in vivo in a clinical UPEC strain. We identified a previously unknown regulatory element that affects T1P expression and coordinates the expression of other pili, processes that facilitate infection by UPEC. This method may enable comprehensive studies of phase variation in other pathogens and other regulated DNA dynamics in general.

Abstract
In southern Idaho, population growth of American white pelicans Pelecanus erythorhynchos at the Blackfoot Reservoir and Lake Walcott colonies since the early 1990s has generated concerns about whether pelican predation is impacting angler catch of hatchery trout stocked in Idaho waters. To evaluate this concern, we estimated rates of pelican predation (i.e., the proportion of fish consumed by pelicans) and angler catch (i.e., the proportion of fish caught by anglers) for 19 unique springtime fish stocking events over 3 years across 12 study waters; where feasible we also estimated double-crested cormorant Phalacrocorax auritus predation. Stocked Rainbow Trout Oncorhynchus mykiss averaged 247 mm in length and were internally PIT-tagged (to monitor bird predation) and externally anchor-tagged (to monitor angler catch) before stocking. Additional hatchery trout were PIT-tagged, euthanized, and fed directly to pelicans to estimate PIT tag deposition rates at the colonies; feeding was unsuccessful for cormorants. After the juvenile pelicans and cormorants fledged in the fall, we recovered PIT tags from stocked and fed fish that were deposited at the two colonies. Deposition rates for pelican-consumed tags averaged 21% and declined exponentially as distance increased from the colonies. Pelican predation on hatchery trout averaged 18% and ranged from 0 to 48%, whereas angler catch averaged 21% and ranged from 0 to 82%. Mean angler catch was nearly four times higher when pelican predation was low (i.e., &lt;25%) than when pelican predation was high (≥25%). Cormorant predation estimates (available for seven stocking events) were minimum estimates only (i.e., they assumed 100% of tags consumed by cormorants were recovered) and averaged 14% (range, 2–38%). Our results suggest that predation by American white pelicans and double-crested cormorants on catchable-sized hatchery Rainbow Trout stocked in southern Idaho waters often exceeds the total catch of those fish by anglers who compete directly with avian predators for use of stocked trout.

n-Culturals: modeling the multicultural identity
Authors: Pekerti Andre Anugerah , Thomas David Clinton 
Published: March 2016

Purpose– The purpose of this paper is to extend current conceptualizations of multicultural individuals by mapping the underlying elements of knowledge, identification, commitment and internalization as components of multicultural identity. It aims to extend discussions of how multicultural individuals manage their multiculturality.Design/methodology/approach– The paper draws primarily on extant works on multicultural individuals and identity. The paper reviews a number of concepts relevant to multicultural identity to introduce the existence of a population calledn-Culturals who represent a complex type that exists on one extreme of a continuum of multicultural identity. The paper derives a theory ofn-Culturalism which represents a more nuanced theory of the multicultural identity.Findings–n-Culturals recognizes that elements of multicultural identity exist within individuals to a greater or lesser extent and that their combination results in a comprehensive understanding of the entire range of multicultural identities.n-Culturalism extends current views that multicultural individuals maintain multiple saliences of their identities rather than switching modes to manage their multiculturality.Research limitations/implications– The conceptual nature of the paper implies that there are no existing empirical data apart from anecdotal examples; at the same time this fact provides ample opportunities to test the theory.Practical implications– First, the findings provides an understanding of multiple cultural influences on acculturative stress and on performance across a range of domains as well as measuring multicultural identity. Second, by understanding the way in whichn-Culturals develop the authors may gain valuable insights in modeling this process.Originality/value– The paper develops a new theory of approaching the challenges faced by multicultural individuals, that is, how to manage their multiculturality. The theory goes beyond current views of switching modes or suppression, and suggests maintaining and balancing multiple identities.
Cost-optimization modelling for fresh food quality and transportation
Authors: Nakandala Dilupa , Lau Henry , Zhang Jingjing 
Published: March 2016

Purpose
– All along the length of the supply chain, fresh food firms face the challenge of managing both product quality, due to the perishable nature of the products, and product cost. The purpose of this paper to develop a method to assist logistics managers upstream in the fresh food supply chain in making cost optimized decisions regarding transportation, with the objective of minimizing the total cost while maintaining the quality of food products above acceptable levels.

Design/methodology/approach
– Considering the case of multiple fresh food products collected from multiple farms being transported to a warehouse or a retailer, this study develops a total cost model that includes various costs incurred during transportation. The practical application of the model is illustrated by using several computational intelligence approaches including genetic algorithms (GA), fuzzy genetic algorithms (FGA) as well as an improved simulated annealing (SA) procedure applied with a repair mechanism for efficiency benchmarking. The authors demonstrate the practical viability of these approaches by using a simulation study based on pertinent data and evaluate the simulation outcomes.

Findings
– The application of the proposed total cost model was demonstrated using three approaches of GA, FGA and SA with a repair mechanism. All three approaches are adoptable; however, based on the performance evaluation, it was evident that the FGA is more likely to produce a better performance than the other two approaches of GA and SA.

Practical implications
– This study provides a pragmatic approach for supporting logistics and supply chain practitioners in fresh food industry in making important decisions on the arrangements and procedures related to the transportation of multiple fresh food products to a warehouse from multiple farms in a cost-effective way without compromising product quality.

Originality/value
– This study extends the literature on cold supply chain management by investigating cost and quality optimization in a multi-product scenario from farms to a retailer and, minimizing cost by managing the quality above expected quality levels at delivery. The scalability of the proposed generic function enables the application to alternative situations in practice such as different storage environments and transportation conditions, etc.
Determinants of continuance intention to use the smartphone banking services
Authors: Susanto Aries , Chang Younghoon , Ha Youngwook 
Published: March 2016

Purpose
– Existing research in the electronic banking area has not deeply investigated the determinants of continuance intention to use smartphone banking services. The purpose of this paper is to attempt to do so by investigating continuance use intention at the post-consumption phase.

Design/methodology/approach
– It developed and validated an extended framework based on the expectation-confirmation model (ECM). A total of 301 smartphone users who subscribed to online banking services participated in the study.

Findings
– The results revealed that users’ confirmation after the initial use of smartphone banking services has significant impact on perceived security, perceived usefulness, trust, and user satisfaction. Perceived security significantly influences trust while perceived usefulness significantly influences trust, user satisfaction, and continuance use intention. Both user satisfaction and self-efficacy also significantly influence continuance use intention. Trust exerts significant impact on user satisfaction. The findings have implications for banks in planning their strategies to increase consumers’ continuance intention to use smartphone banking services.

Originality/value
– Most studies have focussed only technology adoption and have paid little attention on use continuance in the context of electronic or smartphone banking. This manuscript fills the gap by focussing on the post-consumption phase. In special, the manuscript develops an extended framework based on the ECM to address IS use continuance. In addition, the topic is timely as mobile internet has been flourishing in the world.
Postponement and logistics flexibility in retailing: a multiple case study from Sweden
Authors: Jafari Hamid , Nyberg Anna , Hilletofth Per 
Published: March 2016

Purpose– The purpose of this paper is to explore how postponement is applied in retailing and how such application is connected to logistics flexibility.Design/methodology/approach– An overview of the established typological classifications of postponement and logistics flexibility is presented followed by empirical results from three case studies of retailers of electronics, furniture, and grocery in Sweden. The study relies on primary qualitative data gathered on the retailers as well as secondary material on some suppliers including logistics providers for further insight.Findings– The results of the study show that retailers have different practices when it comes to postponement and speculation; however, there is a growing tendency toward postponement among retailers by exploring new means of applying postponement. The results reveal that retailers that have higher application of postponement seem to be more flexible in their logistics operations.Research limitations/implications– The paper provides direction for further empirical research of the topic, by indicating the application of postponement is not constrained to the point of purchase and could be extended by involving consumers as well as capitalizing on suppliers’ competences and capabilities. Especially, sales services, software, and upgrades could provide opportunity for further expanding the concept.Originality/value– The paper contributes to the existing literature on logistics practices of postponement and speculation, as well as logistics flexibility by focussing on retail firms in Sweden. Most of the prior scholarly work on postponement and flexibility is on the manufacturing context.
How preference markets assist new product idea screening
Authors: Lauto Giancarlo , Valentin Finn 
Published: March 2016

Purpose
– The purpose of this paper is to examine the different heuristics adopted by a crowd and a management committee to evaluate new product proposals, and whether, in assessing the value of proposals, they emphasize different features.

Design/methodology/approach
– The study takes a quantitative analysis approach to study an internal innovation contest held by the biotechnology company Novozymes. The contest generated 201 proposals that were evaluated by 109 research and development professionals by means of a virtual preference market, and by a management committee.

Findings
– The crowd and the committees’ assessments of the value of the proposals were based on different features. The committee emphasized experience and inventors’ seniority; the crowd set more store on informative idea descriptions but penalized overly complex and lengthy proposals.

Research limitations/implications
– The design of the innovation contest does not allow full comparison of the preference functions of crowd and committee. The findings from this case study cannot be generalized. The early stage of new product development seems fruitful for investigating crowdsourcing and knowledge management.

Practical implications
– Firms should consider adopting preference markets for idea screening and evaluation since they appraise ideas from different angles compared to managers. However, they complement, rather than substitute managerial evaluation, especially in the case of more detailed proposals.

Originality/value
– This is one of the first attempts to identify differences in the decision-making processes of crowds and committees. The paper identifies their strengths as evaluators of new product ideas and finds that the “wisdom of crowds” has some limitations in relation to the ability to process complex information.
Mastery versus profit as motivation for the entrepreneur
Authors: Manish G.P. , Sutter Daniel 
Published: March 2016

Purpose– The purpose of this paper is to argue that entrepreneurs are motivated not only by the desire to maximize profits but also by the desire for mastery. It then attempts to analyze the implications of mastery seeking for the economics and politics of government privileges and favors for businesses.Design/methodology/approach– Using the existing psychological literature on mastery as motivation the paper first attempts to conceptualize how the desire for mastery manifests itself in the context of entrepreneurship. Next, it attempts to clarify the implications of this for the existing literature on the effects of government policies promoting cronyism.Findings– The paper argues that in business mastery involves producing a good product or service, and validation of the performance occurs via the choices of sovereign consumers. Mastery is thus achieved through participation in a process of competition that is free from government favors. Given that crony polices can disrupt the consumer choice process and consequently the validation of performance, they can therefore affect the types of individuals who become entrepreneurs, with a high level of government intervention pushing success seekers to pursue mastery in other life endeavors, with adverse implications for innovation and growth in the economy.Originality/value– The exploration of implications of a plausible but underexplored motive for entrepreneurs and the interaction between this motive and the effects of various policies fostering cronyism or rent seeking are potential contributions of the paper.
