Nitrogen and sulfur deprivation differentiate lipid accumulation targets of Chlamydomonas reinhardtii

Nitrogen (N) and sulfur (S) have inter-related and distinct impacts on microalgal metabolism; with N starvation having previously been reported to induce elevated levels of the biodiesel feedstock material triacylglycerol (TAG), while S deprivation is extensively studied for its effects on biohydrogen production in microalgae.1,2 We have previously demonstrated that N- and S-starved cells of Chlamydomonas reinhardtii display different metabolic trends, suggesting that different response mechanisms exist to compensate for the absence of those two elements.3 We used C. reinhardtii CC-124 mt(-) and CC-125 mt(+) strains to test possible metabolic changes related to TAG accumulation in response to N and S deprivation, considering that gamete differentiation in this organism is mainly regulated by N.4 Our findings contribute to the understanding of microalgal response to element deprivation and potential use of element deprivation for biodiesel feedstock production using microalgae, but much remains to be elucidated on the precise contribution of both N and S starvation on microalgal metabolism.
Recommendation System Based on Prediction of User Preference Changes

Time always exists in our lives and time data can easily be collected in a variety of applications. For example, when you purchase items online or click on an ad, the time at which you chose the item or clicked the ad is recorded. The analysis of time information can therefore be applied in various areas. It is important to note that user preferences change over time. For example, a person who watched animated TV shows in childhood will most likely switch to watching the news in adulthood. It is effective to incorporate such changes into recommender systems. In this paper, we propose an approach that predicts user preferences with consideration of preference changes by learning the order of purchase history in a recommender system. Our approach is composed of three steps. First, we obtain user features based on matrix factorization and purchasing time. Next, we use a Kalman filter to predict user preference vectors from user features. Finally, we generate a recommendation list, at which time we propose two types of recommendation methods using the predicted vectors. We then show through experiments using a real-world dataset that our approach outperforms competitive methods such as the first order Markov model.
Strategic leadership of ethical behavior in business

Executive Overview The strategic leadership of ethical behavior in business can no longer be ignored. Executives must accept the fact that the moral impact of their leadership presence and behaviors will rarely, if ever, be neutral. In the leadership capacity, executives have great power to shift the ethics mindfulness of organizational members in positive as well as negative directions. Rather than being left to chance, this power to serve as ethics leaders must be used to establish a social context within which positive self-regulation of ethical behavior becomes a clear and compelling organizational norm and in which people act ethically as a matter of routine. This article frames the responsibility for strategic leadership of ethical behavior on three premises: (1) It must be done—a stakeholder analysis of the total costs of ethical failures confirms the urgency for ethics change; (2) It can be done—exemplars show that a compelling majority of an organization's membership can be influenced to make eth.
Association Study on IL4, IL13 and IL4RA Polymorphisms in Mite-Sensitized Persistent Allergic Rhinitis in a Chinese Population

Background The IL4, IL13, and IL4 receptor α chain (IL4RA) genes are candidate genes for atopic diseases. We hypothesized that the polymorphisms in these genes are associated with persistent allergic rhinitis (PER). Objective To investigate the association of the potential functional polymorphisms in IL4, IL13, and IL4RA with PER induced by house dust mites in a Chinese population. Methods Using the TaqMan method, we genotyped six single nucleotide polymorphisms (SNPs) including C-590T in IL4, C-1055T and Arg130Gln in IL13, and Ile50Val, Ser478Pro and Gln551Arg in IL4RA, in a case-control study of 265 patients with PER and 275 healthy controls. Results We found that the CT/CC genotypes in IL4 C-590T were associated with a significantly decreased risk of mite-sensitized PER [adjusted odds ratio (OR) = 0.64, 95% confidence interval (CI) 0.45–0.92], compared to the TT genotype. Furthermore, PER patients with CT/CC genotypes had significantly lower serum levels of total IgE than those with TT genotype (P = 0.001). However, there was no significant association of the IL13 and IL4RA polymorphisms with mite-sensitized PER (P>0.05). Conclusions Our results suggest that the C-590T polymorphism in IL4 may contribute to the susceptibility to mite-sensitized PER in a Chinese population.
Symmetric key image encryption using chaotic Rossler system

In this article, an algorithm for encryption of digital image based on chaos theory is proposed. This encryption algorithm includes two main operations of image element shuffling and pixel replacement. The analysis of cryptographic strength resistance attack has been performed to confirm the fact. The results of several experimental tests, such as key space analysis, key sensitivity analysis, and statistical analysis, show that the proposed algorithm for image cryptosystems provides an efficient and secure way for image encryption and the hacker cannot decrypt an encrypted image without original key. A comparison in terms of correlation between the original and encrypted images, number of pixels change rate, unified average changing intensity, and mean absolute error is performed, which proves that the plain image is very different from the encrypted one. We have also performed fixed point analysis to know how many pixels remain fixed after pixel shuffling operation. Copyright © 2013 John Wiley & Sons, Ltd.
Advancing Content-Based Retrieval Effectiveness with Cluster-Temporal Browsing in Multilingual Video Databases

Interactive experiments on video retrieval systems need to address the problem of internal validity, i.e. how much the test users' experience affects the retrieval effectiveness. This paper compares the semantic retrieval performance of novice users and expert system developers. The test system utilizes cluster-temporal browsing, which combines chronological video structure and computation of similarities into single interface. Interactive experiments with eight test users were carried out in a database of ~80 hours of multilingual news video from TRECVID 2005 benchmark. A cluster-temporal browser was found to improve the retrieval effectiveness by 12% with novice system users. Expert users were able to achieve 18% better performance than the novice users. Additionally, manual search experiments demonstrated that search performance can be improved by 19-25% when a plain text search is supplemented with content-based features
Taming Compiler to Work with Multicore Processors

We present a parallelization scheme involving extracting intra block parallelism within sequential programs which are in SSA form and scheduling block on to multicore processor. Since we are working on SSA form program, we are able to exploit more parallelism compared to existing parallelization compilers. Also an attempt is made to schedule to multiple cores taking by number of registers into consideration. At the end we show how our approach will give solution to direct cache coherence problem.
On wave-action and its relatives

Conservable quantities measuring ‘wave activity’ are discussed. The equation for the most fundamental such quantity, wave-action, is derived in a simple but very general form which does not depend on the approximations of slow amplitude modulation, linearization, or conservative motion. The derivation is elementary, in the sense that a variational formulation of the equations of fluid motion is not used. The result depends, however, on a description of the disturbance in terms of particle displacements rather than velocities. A corollary is an elementary but general derivation of the approximate form of the wave-action equation found by Bretherton & Garrett (1968) for slowlyvarying, linear waves. The sense in which the general wave-action equation follows from the classical ‘energy-momentum-tensor’ formalism is discussed, bringing in the concepts of pseudomomentum and pseudoenergy, which in turn are related to special cases such as Blokhintsev's conservation law in acoustics. Wave-action, pseudomomentum and pseudoenergy are the appropriate conservable measures of wave activity when ‘waves’ are defined respectively as departures from ensemble-, space- and time-averaged flows. The relationship between the wave drag on a moving boundary and the fluxes of momentum and pseudomomentum is discussed.
Quantitative Characterization of the Growth of Deinococcus geothermalis DSM-11302: Effect of Inoculum Size, Growth Medium and Culture Conditions

Due to their remarkable resistance to extreme conditions, Deinococcaceae strains are of great interest to biotechnological prospects. However, the physiology of the extremophile strain Deinococcus geothermalis has scarcely been studied and is not well understood. The physiological behaviour was then studied in well-controlled conditions in flask and bioreactor cultures. The growth of D. geothermalis type strains was compared. Among the strains tested, the strain from the German Collection of Microorganisms (Deutsche Sammlung von Mikroorganismen DSM) DSM-11302 was found to give the highest biomass concentration and growth rate: in a complex medium with glucose, the growth rate reached 0.75 h−1 at 45 °C. Yeast extract concentration in the medium had significant constitutive and catalytic effects. Furthermore, the results showed that the physiological descriptors were not affected by the inoculum preparation steps. A batch culture of D. geothermalis DSM-11302 on defined medium was carried out: cells grew exponentially with a maximal growth rate of 0.28 h−1 and D. geothermalis DSM-11302 biomass reached 1.4 g·L−1 in 20 h. Then, 1.4 gDryCellWeight of biomass (X) was obtained from 5.6 g glucose (Glc) consumed as carbon source, corresponding to a yield of 0.3 CmolX·CmolGlc−1; cell specific oxygen uptake and carbon dioxide production rates reached 216 and 226 mmol.CmolX−1·h−1, respectively, and the respiratory quotient (QR) value varied from 1.1 to 1.7. This is the first time that kinetic parameters and yields are reported for D. geothermalis DSM-11302 grown on a mineral medium in well-controlled batch culture.
The Nature of Verbal Short-Term Impairment in Dyslexia: The Importance of Serial Order

Verbal short-term memory (STM) impairment is one of the most consistent associated deficits observed in developmental reading disorders such as dyslexia. Few studies have addressed the nature of this STM impairment, especially as regards the ability to temporarily store serial order information. This question is important as studies in typically developing children have shown that serial order STM abilities are predictors of oral and written language development. Associated serial order STM deficits in dyslexia may therefore further increase the learning difficulties in these populations. In this mini review, we show that specific serial order STM impairment is frequently reported in both dyslexic children and adults with a history of dyslexia. Serial order STM impairment appears to occur for the retention of both verbal and visuo-spatial sequence information. Serial order STM impairment is, however, not a characteristic of every individual dyslexic subject and is not specific to dyslexia. Future studies need to determine whether serial order STM impairment is a risk factor which, in association with phonological processing deficits, can lead to dyslexia or whether serial order STM impairment reflects associated deficits causally unrelated to dyslexia.
Distribution of BoLA-DRB3 Allelic Frequencies and Identification of Two New Alleles in Iranian Buffalo Breed

The role of the major histocompatibility complex (MHC) in the immune response makes it an attractive candidate gene for associations with disease resistance and susceptibility. This study describes genetic variability in the BoLA-DRB3 in Iranian buffaloes. Heminested PCR-RFLP method was used to identify the frequency of BoLA-DRB3 alleles. The BoLA-DRB3 locus is highly polymorphic in the study herd (12 alleles). Almost 63.50% of the alleles were accounted for by four alleles (BoLA-DRB3.2 ∗48, ∗20, ∗21, and obe) in Iranian buffalo. The DRB3.2 ∗48 allele frequency (24.20%) was higher than the others. The frequencies of the DRB3.2 ∗20 and DRB3.2 ∗21 are 14.52 and 14.00, respectively, and obe and gbb have a new pattern. Significant distinctions have been found between Iranian buffalo and other cattle breed studied. In the Iranian buffaloes studied alleles associated with resistance to various diseases are found.
MULTIOBJECTIVE OPTIMIZATION AND DESIGN OF A LUNEBERG LENS ANTENNA WITH MULTIBAND MULTI-POLARIZED FEED-SYSTEM

A general multiobjective optimization and design proce- dure of a Luneberg lens antenna (LLA) with a compact multiband multi-polarized feed-system for a broadband satellite communication terminal is presented. The LLA utilizes a compact multiband feed horn, consisting of an inner dielectric loaded circular horn for the K/Ka-band (dual-circular polarization) and a coaxial waveguide with axially corrugated ∞ange for the Ku-band (dual-linear polarization). Measurements show good agreements with simulations. Moreover, an e-cient multiobjective evolutionary algorithm based on decomposition (MOEA/D) with difierential evolution operator and objective normal- ization technique is flrstly coupled with the vector spherical wave func- tion expansions (VSWE) for the optimal design of a 7-layer 650mm diameter LLA, which provides higher aperture e-ciency at Ku/K/Ka- band simultaneously. The frequency dependence of the LLA is also investigated. Finally, the gain and sidelobe level of a 5-layer design are jointly evaluated and compared with previous works. The pro- posed design procedure provides much better radiation performances and greater design freedom to the designers, as a group of Pareto- optimal LLA solutions can be obtained with just one simulation.
Modeling Collaborations in Adaptive Systems of Systems

The inherent distributed nature of adaptive Systems of Systems (SoS) raises new demands of modeling, understanding, and managing system interactions. Current modeling languages such as general purpose modeling languages or domain specific modeling languages do not aim at the modeling of distributed, adaptive systems together with their interactions, and their influence on each other as first class entities. Former research shows the applicability of explicit feedback loop modeling to achieve a decoupling of the domain logic from the adaptive capabilities of the overall system, but lacks in specifying interactions of distributed feedback loops. In this paper, we introduce the Deurema modeling language, which provides concepts for the specification of collaborations in adaptive SoS between feedback loops. Thereby, we consider collaborations, the exchanged data in form of runtime models, and the adaptation activities inside the systems as first class entities. Furthermore, we show the applicability of our modeling language by describing two state-of-the-art case studies. Therefore, the Deurema modeling language is a first step towards the explicit description of distributed feedback loops between systems of a SoS.
An Examination of the Association Between Perceived Stress and Memory Performance and the Utilization of Mindfulness as a Memory Enhancer

Objective: Stress levels today among individuals are on the increase due to higher educational and workforce demands. Extensive research has suggested that stress can have major impacts on an individual’s memory functioning. This study aims to investigate the relationship between perceived stress and immediate memory and to examine if mindfulness is an effective stress-reducer, which in turn improves memory scores. Methodology: 43 participants (23 females, 20 males) firstly completed a 10-item Perceived Stress Scale, followed by a pre-intervention Free Recall Memory Task. Participants then took part in a 15-minute mindfulness intervention, and finally, a second post-intervention Free Recall Memory Task was completed. Results: Female students reported the highest amount of perceived stress, revealed from a two-way ANOVA. A Pearson correlation coefficient identified a strong negative correlation between perceived stress and memory scores. A mixed between-within subjects ANOVA indicated that participants memory score significantly improved after participation in the mindfulness intervention, particularly for females. Discussion: Findings from the current study suggest that perceived stress can have a negative impact on immediate memory and that mindfulness is a successful treatment for improving memory scores. Previous literature, implications, and future recommendations are also discussed.

Large-system analysis of rate regions in bidirectional full-duplex MIMO link: Suppression versus cancellation

We analyze the performance of bidirectional communication links between two multi-antenna full-duplex transceivers, explicitly taking into account the effect of unavoidable self-interference. The main theme of this paper is to compare spatial-domain suppression (implemented in the form of null-space projection) and subtractive time-domain cancellation: both schemes can eliminate the self-interference but the former consumes spatial degrees of freedom unlike the latter. We perform large-system analysis based on the replica method, while reference simulations show that the asymptotic results are applicable also for practical systems with low number of antennas. In particular, we evaluate rate regions achieved by controlling the spatial multiplexing order in each node and time sharing between different stream configurations. Consequently, we can characterize the rate loss of suppression versus cancellation.
The Increasing Acceptance of Onscreen Marking - the 'Tablet Computer' Effect

This study extends recent investigations of onscreen marking (OSM) in the Hong Kong public examination context. It examines whether marker attitudes, which have shown increasing acceptance of OSM since it was first introduced in 2007, continue to develop this acceptance in a different context. In 2012, all pubic examinations were marked onscreen. While previous studies investigated the attitudes of mature markers marking extended essay answers for single subjects (English and Liberal Studies), the current study examines the attitudes and perceptions of much younger markers when marking short, objective answer questions in the 2012 Hong Kong Advanced Level Examination Use of English. In addition, because the markers were younger than usual, the issue of whether their attitudes to OSM were affected by the ownership of a tablet computer was also investigated. The findings, which have implications for other examination jurisdictions, indicate a growing acceptance of OSM, especially by tablet owners.
A Biogenerated Polymetallic Catalyst from Society's Wastes

Aims: Preparation of the new metals-polymeric composite, Metx-EPS (I), to be used as a green catalyst in water or in two-phase aqueous conditions. Study Design: Recovery and valorization of polymetallic wastes to obtain directly new catalysts using a microorganism to explore their application in removal of difficult and dangerous chemical pollutants present in aqueous environment. Place and Duration of Study: Dipartimento di Scienze Molecolari e Nanosistemi, Università Ca’ Foscari Venezia, Venezia Mestre, Italy; University of Nova Gorica, Nova Gorica, Slovenia, Institut Jozef Stefan, Ljubljana, Slovenia and Department of Biology, Biotechnical Faculty, University of Ljubljana, Ljubljana, Slovenia, between February 2018 and January 2019. Methodology: For the preparation of Metx-EPS (I), the metals source was an exhausted catalytic converter that was grinded and treated with an acidic solution at 20-25°C. After filtration, the solution was concentrated, neutralized and added to a broth of Klebsiella oxytoca DSM 29614 to produce (I) where metals are embedded in a peculiar polysaccharide structure. The composite was easily recovered from the fermentation broth and purified. The process protocol was verified many times and was shown to be reproducible satisfactorily. The % recovery of metals, originally present in the converter, was good as determined by atomic absorption. The morphology and the chemical state of main metals in (I) were investigated by X-ray absorption spectroscopy methods (XANES and EXAFS). No metallic alloy seems to be evident. Results: As first application of (I) as catalyst, the hydrodechlorination treatment of polychlorinated biphenyls (PCBs) was studied in water/methanol. A significant removal of higher chlorinated congeners was observed working at 1MPA of hydrogen and 60°C. This result improves significantly and surprisingly the methodology, previously studied by us using mono- or bi-metals embedded in the same polysaccharide moiety, indicating that positive synergies among the different metals were operating. Conclusion: The preparation of this new polymetallic species embedded in a polysaccharide moiety starting from spent catalytic converters represents an alternative valorisation of metallic wastes. Moreover, a synergic effect was exerted by the different metals when the catalyst Metx-EPS (I) was used in the hydrodechlorination treatment of polychlorinated biphenyls (PCBs) in water/methanol. Finally, a promising preliminary proof of concept for the removal of polychlorinated aromatic pollutants even in contaminated aqueous sites was carried out.
Is Health Care a Necessity or a Luxury? New Evidence from a Panel of U.S. State-Level Data

This paper estimates the income elasticity of health care expenditures using annual data on health spending by state in the U.S. from 1966-2009. Panel stationarity tests incorporating structural breaks in the levels and trends in Health Care Expenditures and Disposable Personal Income yield inconsistent results, with stationarity rejected for HCE but not for DPI. Regression results using levels estimation robust to orders of integration differed considerably depending on time period, and the cross-state variation in elasticity estimates was quite large. Results of the first difference models provide more consistent estimates across time periods, whether expressed as averages of individual state estimates or as pooled time series. Income elasticities for the full sample fall in the range 0.21-0.22, below that of recent research.
