A study of enterprise resource planning (ERP) system performance measurement using the quantitative balanced scorecard approach
Venue: Comput. Ind.

This study proposed an ERP performance measurement framework based on BSC.The non additive fuzzy integral is applied to measure the ERP performance.The proposed approach reflects the interdependence among performance criteria.The proposed approach reflects the fuzziness existing in experts' judgments. Enterprise resource planning (ERP) systems have been used in integrating information and accelerating its distribution across functions and departments with the aim to increase organizations' operational performance. Thus, it is worth measuring ERP system performance based on its impact to critical performance of an organization: this requires a systematic method that bridges ERP performance measurement and key organizational performance. The hierarchical balanced scorecard (HBSC) model with respect to multiple criteria decision making is such a systematic approach to ERP performance measurement. An ERP evaluation framework that integrates the balanced scorecard dimensions, linguistic variables, and non additive fuzzy integral provides an objective approach to measuring both the performance level of the ERP system and its contribution to the strategic objectives of high tech firms. Taking Taiwan's high tech firms as an example, this study demonstrates the effectiveness of this integrated approach to measure the performance of ERP systems at the post implementation stage under evaluators' subjective, uncertainty, and vagueness judgments.
A new perspective on randomized gossip algorithms
Venue: 2016 IEEE Global Conference on Signal and Information Processing (GlobalSIP)

In this short note we propose a new approach for the design and analysis of randomized gossip algorithms which can be used to solve the average consensus problem. We show how that Randomized Block Kaczmarz (RBK) method a method for solving linear systems works as gossip algorithm when applied to a special system encoding the underlying network. The famous pairwise gossip algorithm arises as a special case. Subsequently, we reveal a hidden duality of randomized gossip algorithms, with the dual iterative process maintaining a set of numbers attached to the edges as opposed to nodes of the network. We prove that RBK obtains a superlinear speedup in the size of the block, and demonstrate this effect through experiments.
Aloe vera extract functionalized zinc oxide nanoparticles as nanoantibiotics against multi drug resistant clinical bacterial isolates.
Venue: Journal of colloid and interface science

ZnO nanoparticles (ZnONPs) were synthesised through a simple and efficient biogenic synthesis approach, exploiting the reducing and capping potential of Aloe barbadensis Miller (A. vera) leaf extract (ALE) ALE capped ZnO nanoparticles (ALE ZnONPs) were characterized using UV Vis spectroscopy, X ray diffraction (XRD) Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) energy dispersive X ray spectroscopy (EDX) and transmission electron microscopy (TEM) analyses. XRD analysis provided the average size of ZnONPs as 15 nm. FTIR spectral analysis suggested the role of phenolic compounds, terpenoids and proteins present in ALE, in nucleation and stability of ZnONPs. Flow cytometry and atomic absorption spectrophotometry (AAS) data analyses revealed the surface binding and internalization of ZnONPs in Gram +ve (Staphylococcus aureus) and Gram ve (Escherichia coli) cells, respectively. Significant antibacterial activity of ALE ZnONPs was observed against extended spectrum beta lactamases (ESBL) positive E. coli, Pseudomonas aeruginosa, and methicillin resistant S. aureus (MRSA) clinical isolates exhibiting the MIC and MBC values of 2200, 2400 mg/ml and 2300, 2700 mg/ml, respectively. Substantial inhibitory effects of ALE ZnONPs on bacterial growth kinetics, exopolysaccharides and biofilm formation, unequivocally suggested the antibiotic and anti biofilm potential. Overall, the results elucidated a rapid, environmentally benign, cost effective, and convenient method for ALE ZnONPs synthesis, for possible applications as nanoantibiotics or drug carriers.
Green synthesis of silver nanoparticles in aloe vera plant extract prepared by a hydrothermal method and their synergistic antibacterial activity
Venue: PeerJ

There is worldwide interest in silver nanoparticles (AgNPs) synthesized by various chemical reactions for use in applications exploiting their antibacterial activity, even though these processes exhibit a broad range of toxicity in vertebrates and invertebrates alike. To avoid the chemical toxicity, biosynthesis (green synthesis) of metal nanoparticles is proposed as a cost effective and environmental friendly alternative. Aloe vera leaf extract is a medicinal agent with multiple properties including an antibacterial effect. Moreover the constituents of aloe vera leaves include lignin, hemicellulose, and pectins which can be used in the reduction of silver ions to produce as AgNPs@aloe vera (AgNPs@AV) with antibacterial activity.  AgNPs were prepared by an eco friendly hydrothermal method using an aloe vera plant extract solution as both a reducing and stabilizing agent. AgNPs@AV were characterized using XRD and SEM. Additionally, an agar well diffusion method was used to screen for antimicrobial activity. MIC and MBC were used to correlate the concentration of AgNPs@AV its bactericidal effect. SEM was used to investigate bacterial inactivation. Then the toxicity with human cells was investigated using an MTT assay.  The synthesized AgNPs were crystalline with sizes of 70.70 22 192.02 53 nm as revealed using XRD and SEM. The sizes of AgNPs can be varied through alteration of times and temperatures used in their synthesis. These AgNPs were investigated for potential use as an antibacterial agent to inhibit pathogenic bacteria. Their antibacterial activity was tested on S. epidermidis and P. aeruginosa. The results showed that AgNPs had a high antibacterial which depended on their synthesis conditions, particularly when processed at 100 oC for 6 h and 200 oC for 12 h. The cytotoxicity of AgNPs was determined using human PBMCs revealing no obvious cytotoxicity. These results indicated that AgNPs@AV can be effectively utilized in pharmaceutical, biotechnological and biomedical applications.  Aloe vera extract was processed using a green and facile method. This was a hydrothermal method to reduce silver nitrate to AgNPs@AV. Varying the hydrothermal temperature provided the fine spherical shaped nanoparticles. The size of the nanomaterial was affected by its thermal preparation. The particle size of AgNPs could be tuned by varying both time and temperature. A process using a pure AG phase could go to completion in 6 h at 200 oC, whereas reactions at lower temperatures required longer times. Moreover, the antibacterial effect of this hybrid nanomaterial was sufficient that it could be used to inhibit pathogenic bacteria since silver release was dependent upon its particle size. The high activity of the largest AgNPs might have resulted from a high concentration of aloe vera compounds incorporated into the AgNPs during hydrothermal synthesis.

Salmonella Typhimurium utilizes a T6SS mediated antibacterial weapon to establish in the host gut
Venue: Proceedings of the National Academy of Sciences

Gram negative bacteria use the type VI secretion system (T6SS) to deliver effectors into adjacent cells. Salmonella Typhimurium is an enteric pathogen that causes disease in millions of individuals each year. Its ability to infect the mammalian gut is a key factor that contributes to its virulence and transmission to new hosts. However, many of the details on how Salmonella successfully colonizes the gut and persists among members of the gut microbiota remain to be deciphered. In this work, we provide evidence that Salmonella uses an antibacterial weapon, the type VI secretion system, to establish infection in the gut. In addition, our results suggest that S. Typhimurium selectively targets specific members of the microbiota to invade the gastrointestinal tract. The mammalian gastrointestinal tract is colonized by a high density polymicrobial community where bacteria compete for niches and resources. One key competition strategy includes cell contact dependent mechanisms of interbacterial antagonism, such as the type VI secretion system (T6SS) a multiprotein needle like apparatus that injects effector proteins into prokaryotic and/or eukaryotic target cells. However, the contribution of T6SS antibacterial activity during pathogen invasion of the gut has not been demonstrated. We report that successful establishment in the gut by the enteropathogenic bacterium Salmonella enterica serovar Typhimurium requires a T6SS encoded within Salmonella pathogenicity island 6 (SPI 6) In an in vitro setting, we demonstrate that bile salts increase SPI 6 antibacterial activity and that S. Typhimurium kills commensal bacteria in a T6SS dependent manner. Furthermore, we provide evidence that one of the two T6SS nanotube subunits, Hcp1, is required for killing Klebsiella oxytoca in vitro and that this activity is mediated by the specific interaction of Hcp1 with the antibacterial amidase Tae4. Finally, we show that K. oxytoca is killed in the host gut in an Hcp1 dependent manner and that the T6SS antibacterial activity is essential for Salmonella to establish infection within the host gut. Our findings provide an example of pathogen T6SS dependent killing of commensal bacteria as a mechanism to successfully colonize the host gut.
Prevalence and antibiotic resistance of Salmonella Enteritidis and Salmonella Typhimurium in raw chicken meat at retail markets in Malaysia.
Venue: Poultry science

Salmonellosis is one of the major food borne diseases in many countries. This study was carried out to determine the occurrence of Salmonella spp. Salmonella Enteritidis, and Salmonella Typhimurium in raw chicken meat from wet markets and hypermarkets in Selangor, as well as to determine the antibiotic susceptibility profile of S. Enteritidis and S. Typhimurium. The most probable number (MPN) in combination with multiplex polymerase chain reaction (mPCR) method was used to quantify the Salmonella spp. S. Enteritidis, and S. Typhimurium in the samples. The occurrence of Salmonella spp. S. Enteritidis, and S. Typhimurium in 120 chicken meat samples were 20.80% 6.70% and 2.50% respectively with estimated quantity varying from <3 to 15 MPN/g. The antibiogram testing revealed differential multi drug resistance among S. Enteritidis and S. Typhimurium isolates. All the isolates were resistance to erythromycin, penicillin, and vancomycin whereas sensitivity was recorded for Amoxicillin/Clavulanic acid, Gentamicin, Tetracycline, and Trimethoprim. Our findings demonstrated that the retail chicken meat could be a source of multiple antimicrobial resistance Salmonella and may constitute a public health concern in Malaysia.
Study of Salmonella Typhimurium Infection in Laying Hens
Venue: Front. Microbiol.

Members of Salmonella enterica are frequently involved in egg and egg product related human food poisoning outbreaks worldwide. In Australia, Salmonella Typhimurium is frequently involved in egg and egg product related foodborne illness and Salmonella Mbandaka has also been found to be a contaminant of the layer farm environment. The ability possessed by Salmonella Enteritidis to colonize reproductive organs and contaminate developing eggs has been well described. However, there are few studies investigating this ability for Salmonella Typhimurium. The hypothesis of this study was that the Salmonella Typhimurium can colonize the gut for a prolonged period of time and that horizontal infection through feces is the main route of egg contamination. At 14 weeks of age hens were orally infected with either S. Typhimurium PT 9 or S. Typhimurium PT 9 and Salmonella Mbandaka. Salmonella shedding in feces and eggs was monitored for 15 weeks post infection. Egg shell surface and internal contents of eggs laid by infected hens were cultured independently for detection of Salmonella spp. The mean Salmonella load in feces ranged from 1.54 to 63.35 and 0.31 to 98.38 most probable number/g (MPN/g) in the S. Typhimurium and S. Typhimurium S. Mbandaka group, respectively. No correlation was found between mean fecal Salmonella load and frequency of egg shell contamination. Egg shell contamination was higher in S. Typhimurium S. Mbandaka infected group (7.2% S. Typhimurium, 14.1% S. Mbandaka) compared to birds infected with S. Typhimurium (5.66% however, co infection had no significant impact on egg contamination by S. Typhimurium. Throughout the study Salmonella was not recovered from internal contents of eggs laid by hens. Salmonella was isolated from different segments of oviduct of hens from both the groups, however pathology was not observed on microscopic examination. This study investigated Salmonella shedding for up to 15 weeks p.i which is a longer period of time compared to previously published studies. The findings of current study demonstrated intermittent but persistent fecal shedding of Salmonella after oral infection for up to 15 weeks p.i. Further, egg shell contamination, with lack of internal egg content contamination and the low frequency of reproductive organ infection suggested that horizontal infection through contaminated feces is the main route of egg contamination with S. Typhimurium in laying hens.
k Nearest Neighbor Model for Multiple Time Step Prediction of Short Term Traffic Condition

AbstractOne of the most critical functions of an intelligent transportation system (ITS) is to provide accurate and real time prediction of traffic condition. This paper develops a short term traffic condition prediction model based on the k nearest neighbor algorithm. In the prediction model, the time varying and continuous characteristic of traffic flow is considered, and the multi time step prediction model is proposed based on the single time step model. To test the accuracy of the proposed multi time step prediction model, GPS data of taxis in Foshan city, China, are used. The results show that the multi time step prediction model with spatial temporal parameters provides a good performance compared with the support vector machine (SVM) model, artificial neural network (ANN) model, real time data model, and history data model. The results also appear to indicate that the proposed k nearest neighbor model is an effective approach in predicting the short term traffic condition.
A statistical assessment of pesticide pollution in surface waters using environmental monitoring data: Chlorpyrifos in Central Valley, California.
Venue: The Science of the total environment

Pesticides are routinely monitored in surface waters and resultant data are analyzed to assess whether their uses will damage aquatic eco systems. However, the utility of the monitoring data is limited because of the insufficiency in the temporal and spatial sampling coverage and the inability to detect and quantify trace concentrations. This study developed a novel assessment procedure that addresses those limitations by combining 1) statistical methods capable of extracting information from concentrations below changing detection limits, 2) statistical resampling techniques that account for uncertainties rooted in the non detects and insufficient/irregular sampling coverage, and 3) multiple lines of evidence that improve confidence in the final conclusion. This procedure was demonstrated by an assessment on chlorpyrifos monitoring data in surface waters of California's Central Valley (2005 2013) We detected a significant downward trend in the concentrations, which cannot be observed by commonly used statistical approaches. We assessed that the aquatic risk was low using a probabilistic method that works with non detects and has the ability to differentiate indicator groups with varying sensitivity. In addition, we showed that the frequency of exceedance over ambient aquatic life water quality criteria was affected by pesticide use, precipitation and irrigation demand in certain periods anteceding the water sampling events.
Evaluation of surface water quality and heavy metal pollution of Coruh River Basin (Turkey) by multivariate statistical methods
Venue: Environmental Earth Sciences

In this study, it was aimed to investigate the water quality data and heavy metal analysis results in Coruh basin by using multivariate statistical analysis methods. Measurement of 21 water quality parameters was evaluated by collecting monthly samples between June 2014 and May 2015 from 14 monitoring sites in Coruh basin. These data were interpreted by using statistical methods such as analysis of variance (ANOVA) cluster analysis, factor analysis/principal component analysis. According to ANOVA analysis, there are statistically significant differences between samples obtained from these 14 monitoring sites in terms of electrical conductivity, Zn, Cd, Cr, Cu, Fe, Mn, NO2, SO4, alkalinity, Na, K, Ca parameters (p 0.05) Two groups were obtained by cluster analysis. The first group consists of the areas with wastewater of mining fields with high heavy metal pollution, and the second group includes areas with domestic wastewater and wastewater coming from agricultural areas causing less pollution. As a result of factor analysis/principal component analysis, four factors were determined. These four factors explain 62.7 of the data of water quality. It is concluded that water quality is affected by mining activities, domestic wastewater, geological structure and wastewater of agricultural areas. In this study, environmental hazards affecting the water quality of Coruh river basin at different points are identified. Thus, it is expected to guide decision makers and administrators in environmental management works conducted to improve water quality in Coruh basin.
