Genetic and physiological classification of periplasmic-leaky mutants of Salmonella typhimurium

Mutants of Salmonella typhimurium that leaked periplasmic proteins were isolated. Four classes of mutants were identified by their increased sensitivity to dyes, detergents, or antibiotics. Conjugation studies indicated that representatives of two classes mapped in the proA-galE region of the Salmonella chromosome and two in the cysI-argE region. According to their bacteriophage sensitivity pattern, all four of the mutant classes appear to retain the smooth lipopolysaccharide characteristic. One class of mutants has an abnormal cell envelope in which the outer membrane balloons away from the murein layer.
The Impact of Free Primary Education on Access and Quality of Primary Education in Lesotho

Abstract Although the Government of Lesotho progressively introduced Free Primary Education in 2000, many children still do not attend school. By reviewing literature, this conceptual article identifies the following factors that hamper access, quality and completion of primary education: grinding poverty facing many families especially in the rural areas, and the herd boy phenomenon, where young boys of school-going age look after livestock or engage in other forms of child labour. The antischool practices such as the initiation school, a rite of passage for boys, also reduce their participation since it clashes with the school calendar year and school ethos. Some school factors such as ineffective teaching, a critical shortage of physical facilities and resources, especially in the rural schools where most teachers are unqualified, also discourage some children from attending school, and many parents from sending their children to school. To increase access this article recommends collaboration between different multi-level stakeholders.
Estrogen and Transdiagnostics: A Systematic Review

Objective: To evaluate, through systematic review, whether the role of estrogen influences the onset of disorders in anxiety and depression. Data Sources: The search was performed in two databases, ISI Web of Science and PubMed, using the terms estrogen, anxiety and mood. Study selection: The search produced 1060 references. Those that were repeated or not written in English were excluded. After analysis of the abstracts, 38 were selected to have their texts read, of which 18 were chosen for the execution of this review. Data collection: The PubMed and ISI Web of Science articles were extracted in June 2015. Moreover, the study was also restricted to articles that involved adult patients and were elaborated between 2005 and 2015. Results: There were six case-control observational studies, followed by four randomized clinical trials. The results in smaller quantities in the review were: three retrospective cohort observational studies and three cross-sectional studies, followed by one prospective cohort observational study. A letter to an editor was also included. The result that stood out in the review was the finding that women are twice as likely to suffer from disturbances of anxiety or mood, such as generalized anxiety disorder, panic disorder, post-traumatic stress disorder and bipolar disorder. Conclusion: Some women there is a greater vulnerability to hormonal oscillations of estrogen (in pre-menstrual and postpartum periods and in the pre-menopause) leading to the aforementioned disorders
Recognition of partial discharge defects in cable terminations

As reported in very researches, the majority failure mechanism in cable terminations is predominantly involving partial discharge deterioration caused by voids, contaminants and protrusion. The partial discharge measurement is an effective way to detect such defects. However, no research shows the relation between the magnitude of partial discharge and remaining life of cable termination. Hence, it is hard to make decision to replace the unqualified cable termination immediately or lately for an in-service cable termination, while the partial discharge activities are measured. Based on authorspsila experiences, different defects have different ageing speed to breakdown. Therefore, recognition of defects is an alternative way to assess the degree of risks. This paper sets up a series test to figure out the properties of partial discharge activities caused by different defects, including wrong position of stress cone, void left, tape left, and needle pricked. Test results show the different properties of different defects, and these characteristics can be used to recognize defects inside cable termination.
Disturbances Classification Based on a Model Order Selection Method for Power Quality Monitoring

In this paper, a new technique for power quality disturbance classification is proposed. It focuses on voltage sags and swells that are first preclassified into four classes that depend on the number of nonzero symmetrical components and can contain different types of sag and swell. Using the estimated symmetrical component values, we can afterward classify the corresponding sag or swell signature. In this study, we show that the preclassification can be reformulated as a pure model order selection problem. To solve this problem, we propose two preclassifiers based on Information Theoretical Criteria. The former yields the highest statistical performances, whereas the latter has a lower computation complexity. The performances of the proposed classification algorithms are evaluated using Monte Carlo simulations on synthetic signals and using real power system data obtained from the DOE/EPRI National Database of Power System Events. The achieved simulations and experimental results clearly illustrate the effectiveness of the proposed algorithms for voltage sag and swell classification.
Iterative Decoders Robust to Threshold Voltage Uncertainty

In this presentation, we provide an analysis of the sensitivity of finite-alphabet iterative decoders (FAID) for low-density parity check (LDPC) codes to a threshold/reference voltage uncertainty in Flash memory channels. We show that optimizing the FAID message update function makes a decoder tolerant to the log-likelihood ratio quantization-threshold mismatch, and improves greatly the robustness of the decoder compared to the classical Min-Sum decoder.
Histological changes in appendix tissues during Acute appendicitis

Appendicitis is an inflammation of the inner lining of the vermiform appendix spreads to the other parts. A total of twenty-three specimens from patients in surgery department in Tikrit Teaching Hospital were collected during the period from first January –end of February 2003 (16 male and 7 female ) age ranged from 5-15 years. The presence of extra vascular polymorphs in the epithelium, lamina propria, and muscular layers was the main diagnostic feature of the acute inflammation. Mucosa was largely destroyed with an extensive neutrophil infiltrate extending throughout the submucosa and into the muscularis externa. This was seen in all the specimens. This paper was designed to study the changes that occur in the appendix’s tissues as a result to acute appendicitis.
Fixing the UPCC case of Split-or-Johnson

In November 2015 I announced the result that Graph Isomorphism can be tested in quasipolynomial time. The first version of the full paper was posted on arXiv in December 2015, and an updated version in January 2016 (arXiv:1512.03547). Below we refer to Version 2 (Jan 2016) of that paper as [Q2]. On January 1, 2017, Harald Helfgott pointed out an error in the timing analysis of one of the combinatorial Divide-and-Conquer tools, the “Split-or-Johnson” routine (SoJ). The error invalidated the quasipolynomial claim. A revised analysis of a slightly modified algorithm (adjusting a threshold parameter for optimal analysis) gave a running time bound of exp exp(Õ( √ log n)) where the Õ hides a poly-loglog term. While still subexponential (less than exp(n ) for all positive ) and thus considerably stronger than the previously known moderately exponential bound of exp(Õ( √ n)) (Luks, 1983), this bound was not quasipolynomial. I announced the revised bound on my home page on January 4, 2017. Three days later I found a simple fix and announced this on January 9, 2017 both on the website and in a lecture I gave that day at Georgia Tech. So the quasipolynomial claim has been restored. Meanwhile I have been working on a major revision of the arXiv posting, taking into account a large number of helpful comments from colleagues. The intention of the update is to improve the presentation, give more detailed proofs and analysis, and also to fix another, less dramatic, error that was pointed out to me by Jin-Yi Cai in Spring 2016; that error occurred in the “Design Lemma” algorithm (DL). My analysis of the modified algorithm for the DL was additionally verified by Gábor Tardos and by Harald Helfgott, both of whom also contributed many comments on how to improve the presentation. Since the completion of the revision of the paper is still months away, and given the explosive interest in the recent (SoJ) update, I decided to post this update in advance of the revision of the full paper. I will also post the DL update in the near future. This note requires some familiarity with [Q2]. The error was in Case 8(iii) (“uniprimitive (UPCC) case”) of the “Bipartite Split-orJohnson” algorithm (Sec. 7.5 in [Q2]) to which the proposed solution (Sec. 7.9 in [Q2]) involved a recursive call to the “UPCC Split-or-Johnson” algorithm. This recursive call caused an impermissible blow-up in the running time. The present note shows how to replace this “malignant” recursive call by a “benign” one that leads to the same type of recurrence that occurs in many other places in the paper and leads to a quasipolynomial solution. This update also subsumes Case 8(iv) (“Johnson case”) of the “Bipartite Split-or-Johnson” algorithm; consequently, that case (Secs. 7.10 and 7.11 in [Q2]) is now eliminated.
Asset Depletion among the Poor: Does Gender Matter? The Case of Urban Households in Thailand

The paper analytically and empirically examines the issue of gender inequality in household wealth in the form of tangible assets among urban poor households Thailand. It seeks to answer the following questions: (1) is there a gendered pattern of asset ownership between husbands and wives; 2) during times of crises, is there a gendered pattern of asset depletion and 3) does asset depletion impact on men and women differently in regards to their income earnings capabilities? The answers are especially important since asset ownership and access impact the form of coping mechanisms and income earnings of men and women, hence on their individual well-being as well as the longer term well-being of the household. This paper joins in the recent efforts in the literature in investigating gender differences in asset ownership and depletion. In particular, we explore analytically and empirically this type of gender inequality among 135 couples, with and without dependents using quantitative and qualitative data drawn from a random sample of 152 urban, low-income households in Bangkok (Thailand) in 2002. The multi-purpose survey included information at the level of the individual respondent on accumulated tangible or physical assets as well as the status of those owned assets six months later. Both husband and wife were interviewed separately and the data gathered from the multi-visit interviews include pertinent household and individual information, employment, credit as well as household decision making issues, division of tasks and earnings allocation for various expenses. Tobit and probit tests are used to examine the varied factors that may affect the gendered pattern of asset depletion and whether there are any significant differences in asset depletion between men and women in the same households. In addition, two probit models are estimated in order to determine the effects of various individual and household characteristics on the probability of pawning or selling real assets and more specifically, business-related assets . The empirical results demonstrate that, alongside gender equality in employment opportunities and earnings, there is need to raise the importance of and promote advocacy for gender equality in wealth and assets, both public as well as private, and for policy interventions that addresses the gender-wealth gap.
An Overview of Bioethanol Production From Algae

The depletion of fossil fuels which meet most of our energy requirements in near future and the pollutants from fossil fuels necessitates the usage of alternative renewable energy sources extensively. In this context, biomass is considered as an important alternative energy source to fossil fuels. Biodiesel and bioethanol produced from biomass sources are one of the best alternatives for petroleum-based fuels and recently, they are commonly used for transporta‐ tion in many countries. Bioethanol is the most produced biofuel in the world and especially in Brazil and the United States two main producing countries with 62% of the world produc‐ tion. Large scale manufacture of ethanol as fuel is performed from sugar cane in Brazil, while it is produced from corn as a raw material in the United States [1]. Bioethanol production of 2013 in the countries is given in Table 1 [2].
Driver Cognitive Distraction Detection Using Driving Performance Measures

Driver cognitive distraction is a hazard state, which can easily lead to traffic accidents. This study focuses on detecting the driver cognitive distraction state based on driving performance measures. Characteristic parameters could be directly extracted from Controller Area Network-(CAN-)Bus data, without depending on other sensors, which improves real-time and robustness performance. Three cognitive distraction states (no cognitive distraction, low cognitive distraction, and high cognitive distraction) were defined using different secondary tasks. NLModel, NHModel, LHModel, and NLHModel were developed using SVMs according to different states. The developed system shows promising results, which can correctly classify the driver’s states in approximately 74%. Although the sensitivity for these models is low, it is acceptable because in this situation the driver could control the car sufficiently. Thus, driving performance measures could be used alone to detect driver cognitive state.
In vivo Spectroscopy and Imaging of Nitroxide Probes

Book chapter from "Nitroxides - Theory, Experiment and Applications", edited by Alexander I. Kokorin, ISBN 978-953-51-0722-4, Hard cover, 436 pages, InTech, September 12, 2012. DOI: 10.5772/2887
An approach in dual-control of battery energy storage systems in windfarm output power smoothing

Intermittent nature of wind power impacts negatively on power system stability, reliability and power quality. These phenomenon challenges the large-scale wind power integration to the electric grid. The Battery Energy Storage System (BESS) can contribute to the mitigation of the intermittency behavior of wind power output, which provides added benefit in large-scale integration of wind farms. This paper proposes a dual control strategy of BESS for Doubly Fed Induction Generator (DFIG) based wind farm output power smoothing to provide nearly constant power at wind farm's output terminal. Dual control of two-stage BESS charging/discharging allows regulating the wind farm power to be as smooth as possible.
Similar long-term outcome for arterial myocardial revascularization performed after or within the first seven day of acute myocardial infarction

The current practice of myocardial revascularization for acute myocardial infarction (MI) is primary percutaneous intervention (PCI). Surgical revascularization (“bypass”) is reserved for patients unsuitable for PCI. The purpose of this report is to describe the long-term outcome of acute MI patients who underwent left-sided arterial revascularization (left anterior descending and circumflex arteries) before PCI was adopted as the preferred treatment for this subset of patients. Between 1996 and 2002, 434 consecutive patients in our center underwent myocardial revascularization for recent MI using the composite T-graft technique (381 bilateral internal thoracic arteries and 53 single internal thoracic artery and radial arteries). Two-hundred and seventy-six patients were operated on within seven days of an acute MI (Group A) and the remaining 158 patients were operated on after the 7th day since an acute MI (Group B). Group A had significantly increased operative mortality (6.5% vs 1.3% for Group B, P = 0.012). Surgery performed within the first week of an acute MI was also found to be a significant predictor of early mortality in multivariate logistic regression analysis (O.R. 10.31; 95% C.I. 1.32-83.30, P = 0.026). The mean follow-up was 10.6 ± 5.2 years. The Kaplan Meier 10-year survival of the two groups, however, was similar (65.6 ± 2.9 Group A vs 64.6 ± 3.8 Group B, P = 0.953), and assignment to Group A was not an independent predictor of decreased survival (P = 0.395, Cox model). When using arterial grafts for myocardial revascularization, the long-term outcome of patients operated on during the first 7 days of acute MI is not worse than that of patients operated on after more than 7 days, despite their increased operative mortality.
Performance analysis of MC-CDMA systems employing maximal ratio combining and uniform linear antenna array

This paper presents exact analytical expressions to evaluate the mean symbol error rate (SER) and the mean bit error rate (BER) of Multicarrier Code Division Multiple Access (MC-CDMA) systems using a correlation receiver with maximal ratio combining (MRC) and uniform linear antenna array at the base station. The performance is evaluated considering additive white gaussian noise (AWGN), Rayleigh fading, multiple access interference (own cell interference) and co-cell interference. Simulations using the Monte Carlo method are carried out, which are compared with the analytical expressions. An asynchronous uplink case with independent fading at different subcarriers is considered and BPSK and M-QAM modulations are used.
Proposed model to evaluate the impact of e-training on work performance among IT employees in Malaysia

The revolutionary development of e-training has made its way into Malaysian organisations, and the most obvious defect of the evolving technology is the focus on the technology (the “e”) and not in the training. This paper seeks to review on how e-training among IT employees affect their performance at work. Furthermore, it is intensively important to evaluate the effect of e-training towards the performance of employee since IT organisation fundamentally depends on the expertise of the employees which demands a constant refurbishment due to rapid technological change. Therefore, this study will propose a research model to evaluate the effectiveness of e-training towards work performance.
Missing Data in Longitudinal Studies: Strategies for Bayesian Modeling and Sensitivity Analysis by DANIELS, M. J. and HOGAN, J. W

In most studies, the intended (full) data, i.e., the data that the study investigators wish to collect, are inevitably incompletely observed. In modern studies, the full data are typically high dimensional, usually comprising many baseline and timevarying variables. Scientific interest, however, often focuses on some low-dimensional parameter of the distribution of the full data. Specification of realistic parametric models for the mechanism generating high-dimensional data is most often very challenging, if not impossible. Nonparametric and semiparametric models, i.e., models in which the data-generating process is characterized by parameters ranging over a large, non-Euclidean, space and, possibly, also a few meaningful real-valued parameters, meet the analytic challenge posed by these high-dimensional data because they do not make assumptions about the components of the full data distribution that are of little scientific interest. Analytic strategies based on semiparametric models avoid the possibility of incorrect inferences due to misspecification of models for the secondary parts of the full data law. Drawing from the modern theory of semiparametric efficient inference developed since the 1980s, Robins and Rotnitzky (1992) derived a general estimating equations methodology in coarsened, i.e., incompletely observed, data models under nonor semiparametric models for arbitrary full data configurations. This methodology, based on the geometry of scores and influence functions, applies when the
How does Economic Integration Change Personal Income Taxation? Evidence from a new Index of Potential Labor Mobility

In this paper, I estimate the effect of increasing labor mobility on personal income tax schedules. I combine rich data on effective personal income tax levels in a panel of OECD countries for the period 1986-2005 with a new Index of Potential Labor Mobility. This index allows to tackle issues of reverse causality and potentially confounding effects from strategic competition. Estimates show that increasing labor mobility accounts for a considerable part of lower tax burdens. Furthermore, the reduction is found to be constant across brackets of taxable income.
Comparative study of PI controller and quadratic optimal regulator applied for a converter based PHiL grid emulator

This paper presents the modelling and control algorithms comparison of a PHiL grid emulator which is based on a two level inverter with LC output filter. The grid emulator is controlled to emulate not only the stable state but also the typical transient of a utility grid. A 5kVA prototype PHiL emulator is implemented in our lab. By means of this grid emulator, the typical fault 0% voltage trip is emulated for the grid-connected equipment under test (EUT) which is represented by a RL load bank. In this work, both PI controller and linear quadratic optimal regulator (LQR) are applied, the comparative evaluation are made regarding their performance and implementation effort.
Behavior-intention analysis and human-aware computing: Case study and discussion

In this paper, we mainly focus on human-aware computing and its applications in collaborative interaction. Several aspects including human recognition, behavior awareness, and intention analysis are discussed. A driving behavior case study has been presented to show how different factors, such as information, intention, mood, and stress, affect driving behavior. This study serves as a base for behavior-intention analysis and modeling human-awareness in human-computer interaction (HCI).
Heat Transfer Analysis in a Rectangular Duct Without and With Cross-Flow and an Impinging Synthetic Jet

A synthetic jet is a zero-net-mass-flux device, which synthesizes stagnant air to form a jet, and is potentially useful for cooling. Due to the inherent suction and ejection processes in a synthetic jet, its utility in a confined enclosure is not obvious. The synthetic jet impingement heat transfer characteristics inside a rectangular duct are studied in this paper. In addition, the effect of cross-flow created using either fans or another synthetic jet on its heat dissipation capability is examined. Experiments are conducted for different jet Reynolds numbers (Re), in the range of 950-4000, at different offset positions of the synthetic jet with respect to a heated block flush mounted on one surface of the duct. The height of the duct is the same (25 mm) for all measurements while the width is varied between 110 mm and 330 mm in order to examine the effect of confinement on the heat transfer coefficient. The change in the width of the duct is found to have a negligible effect on heat transfer. The heat transfer coefficient is found to be more with synthetic jet direct impingement (150 W/m2 · K) than with combined flow (both impingement and cross-flow) (134 W/m2 · K) or with only cross-flow (45 W/m2 · K) in the duct. The offset of the synthetic jet from the center of the heated block is found to drastically reduce the heat transfer. These results are expected to be useful for designing synthetic jet-based cooling solutions.
