Contrarily to classical information retrieval systems, the systems that treat structured documents include the structural dimension through the document and query comparison. Thus, the retrieval of relevant results means the retrieval of document fragments that match the user need rather than the whole document. So, the structure notion should be taken into account during the retrieval process as well as during the reformulation by relevance feedback way. In this paper we propose an approach of query reformulation based on structural relevance feedback. We start from the original query on one hand and the fragments judged as relevant by the user on the other. Structure hints analysis allows us to identify nodes that match the user query and to rebuild it during the relevance feedback step. The main goal of this paper is to show the impact of structural hints in XML query optimization. Some experiments have been undertaken into a dataset provided by INEX (INitiative for the Evaluation of XML retrieval, an evaluation forum that aims at promoting retrieval capabilities on XML documents) to show the effectiveness of our proposals.


Accepted for publication in \Computational Mechanics" Abstract Reproducing Kernel Particle Methods (RKPM) with a built-in feature of multiresolution analysis are addressed. Some fundamental concepts such as reproducing conditions, and correction function are constructed to systematize the framework of RKPM. In particular, Fourier analysis, as a tool, is exploited to further elaborate RKPM in the frequency domain. Furthermore, we address error estimation and convergence properties. We present several applications which connrm the widespread applicability of multiresolution RKPM.

Objective To investigate the expression of CD4+/ CD8+ T lymph cells in the lesions of lupus erythematosus(LE).Methods The skin lesions of 30 patients with LE were observed with immunohistochemistry and 17 normal specimens were taken as controls.Results The percentage of CD4+ T lymph cells in lesions of LE was higher than that of control,while CD8+ T lymph cells in lesions of LE was lower than that of control.Conclusion It suggest that the activity of CD4+ T lymph cells was increased,and CD4+ T lymph cells was depressed in patients with LE,which may lead to immunity disorder.


In this thesis we attempted to suggest the basic data needed in the marketing strategy of sports tourism by figuring out the relation between the recognized value and selective action of the customers using sports tourism. In this respect we executed a survey targeting 250 persons of men and women residing in the metropolitan area, and analyzed the collected data by using a statistic program of SPSS 13.0 and AMOS 5.0. As a result, it was noted that sports tourism participants had a meaningful effect upon the tourism satisfaction, oral tradition intention and re-participation intention respectively through the recognized value on sports tourism. Therefore, sports tourism managers or policy managers shall have to build the related infra-structure by enhancing visitors' satisfaction so that sports tourism may become making good use of spare time together with rest and health instead of the dimension of simple one-time sightseeing and develop tourism contents for sight and enjoyment. Especially they shall have to establish a marketing strategy to satisfy visitors by providing service for visit satisfaction dealing with sports tourism in the dimension of leisure and the phase of living sports.


Critical success factors simplified: implementing the powerful drivers of dramatic business improvement, edited by Marvin T. Howell, is a practice-oriented book that provides guidance on how to identify and select the right Critical Success Factors (CSFs), how to measure their impact, and how to adjust them in order to reach your goals. In this rapidly changing world, it is necessary for organisations, department managers and team members to understand the critical organisational factors for success. Organisations and their people need to identify which objectives and goals need to be reached and which processes need to be installed to really make the difference. This book aims to guide the reader on how to identify the CSFs and how to translate them into concrete action programmes. The first chapter describes the four types of CSFs as defined by Rockart (1986). Rockart makes a distinction between industry, strategic, environmental, and temporal factors. The author also explains how these critical factors can be applied to organisations, how they can be categorised, and why it is important for an organisation to implement CSFs. The second and third chapters elaborate on how external and internal CSFs can be identified. Environmental scans help organisations to analyse which government, industry, economic, technological and social factors can help with identifying external CSFs. The factors retrieved from this environmental scan have to be evaluated and have to be graded according to their importance. Furthermore, this information can be translated into a strategic plan by using SWOT Analysis. Next, the third chapter describes three methods that can be used to identify internal CSFs: the original CSF method, the Five-Phase CSF method, and the ''very simple method''. In summary, the chapter concludes that it is initially important to define a clear vision, mission, and goals from which critical actions and activities have to be derived. The fourth chapter explains in more detail how the appropriate CSFs can be selected, how implementation progress can be measured and how and when corrective actions need to be taken. Different methods are described in detail on how the implementation progress of those CSFs can be measured. The chapter concludes by giving a process example on how this model can be put into practice. The next chapter describes how the vision and mission need to be defined in objectives and how critical success should be identified to reach those objectives. Finally, the relationship between Key Result Areas and CSFs in strategic planning is explained. A practical example is given in Chapter 6. Chapter 7 elaborates on how CSFs can play a major role in ensuring that systems are implemented in a timely fashion, measuring the implementation progress of CSFs and addressing barriers encountered. The author explains how managers can enable continuous improvement by implementing and managing CSFs and define a CSF improvement plan. Furthermore, the book also highlights the benefits of benchmarking.


A large amount of literature exists on how native speakers derive and process pragmatic inferences, yet few studies have examined the issue in second language learners, despite a controversial debate of second language (L2) ultimate attainment of phenomena situated at external interfaces. This study contributes to the debate on the integration of external interfaces in highly proficient end-state adult L2 grammars. In an effort to bridge the empirical gap in the past literature, this article reports on two sentence-picture verification tasks designed to test the processing cost of the exhaustive inference associated with cleft sentences in the L2 French of English learners with different proficiency levels. Truth-value judgments and reaction times were recorded in contexts that violated or supported the exhaustive inference. Overall, results show that L2 learners diverge from the natives in their online processing of the exhaustive inference only and that proficiency plays an important role in predicting their behavior. Nevertheless, what post-hoc observations of the data reveal is that L2 length of exposure to native input might be an even better predictor, since only those L2 speakers who have had more exposure to native French input compute the exhaustive inference in clefts as fast as French natives.


This report is an account of the investigation of UV-sensitivity of a gas proportional counter. The detector used in this investigation has been developed for the observation of low-energy cosmic X-rays; i.e. 0.05-2.0 keV. A major source of background at very low energies (<0.2 keV) is due to the sensitivity of the counter to UV-radiation of stellar origin in the wavelength band 1600-3000 A. The purpose of this investigation is to establish in a quantitive way the parameters governing the UV-sensitivity of a gas proportional detector.


This article aims to discuss the roles of media in shaping and sustaining personal memories of social movements. Through 24 in-depth interviews with witnesses of and participants in two mass protests in Hong Kong, it examines how media might contribute to differences in individual remembering. First, it found that individual remembering was characterized by a strong embodiment of various senses, experiences, and emotions. Second, personal memory was articulated and embedded in layers of social relations. Finally, media were often remembered as tools of mobilization by activists in protests. It argued that two key conditions were crucial for the formation of lasting personal memory: the presence of embodied experiences, and meaningful social connections. It shed light on the roles of media in terms of technology and generations. It identified how changing media technologies facilitated information environments that emphasized on different senses and hence favoring certain experiences, emotions, interpretations, and participation in the memory-making process.

Scientific disciplines build on social structures, such as scholarly associations and scholarly journals, that facilitate the formation of communities of specialists. Analyses of such social structures can thus also be used to shed light on the morphogenesis of scientific specializations. The authors analyze how two journals of the American Educational Research Association, the Review of Educational Research and the American Educational Research Journal, organized communication around education in the period between 1931 and 2014. The authors focus on three interrelated aspects: (a) the changing structures of authority and authorship, (b) the national-versus-global orientation of these journals and of the association, and (c) the features of the citation networks of both journals and the ties between education research and other fields of research, especially psychology and sociology. The authors' analyses of these interrelated aspects of the communication process enable them to provide an outline of the morphology of the community of education researchers and to raise reflectivity about the social conditions that control education research.


Abstract : Three groups of thirty pilots with multi-engine and instrument ratings performed a simulated flight mission in a General Aviation Trainer on each of two days. The experimental conditions for the groups differed in terms of GAT-2 motion: no motion; sustained linear, scaled-down analog motion; and washout motion. Each group of pilots then flew the same mission in a light twin-engine aircraft representative of the class of aircraft simulated by the GAT-2. The results indicated that the proficiency of aircraft pilots can be predicted to a high degree from ground-based simulator performance measures. (Modified author abstract)


Introduction: Despite significant advancements, ruptured abdominal aortic aneurysm (rAAA) remains a life-threatening condition, and the decision whether or not to proceed with surgical intervention is extremely difficult in daily practice. Previous risk prediction models of rAAA mortality developed before EVAR was an option, had their validity questioned in an era where both open repair (OR) and EVAR are available. In 2017, Healey CT et al and von Meijenfeldt GC et al (Dutch Aneurysm Score) published two new mortality prediction models, both based on easily obtained clinical variables and validated in a population submitted to either OR or EVAR. The purpose of this paper was to describe the evolving experience in rAAA management in our centre, and to validate the applicability of the aforementioned scores in our practice.
Methods: The clinical data of all patients admitted in our hospital from 2010 to 2016 with the diagnosis of rAAA were retrospectively reviewed and statistical analysis using SPSS V.22 was performed.
Results: A total of 71 patients were considered, including 19 EVARs and 52 ORs. There was a significant increase over time in repairs performed by EVAR, and in 2015 the annual rate of EVAR exceeded that of OR. The population of patients submitted to EVAR and OR were comparable in gender, age and co-morbidities with the exception of smoking, more common in the EVAR group (73.7% Vs 36.5%; p=0.005). No cases of intra-operative mortality were registered in the EVAR group, as opposed to 17% in the OR group (p=0,049). 30-day mortality reached 49% in the OR group and 31,6% in the EVAR group (p>0.05). Several pre-operative predictors of outcome were identified: smoking (p=0.005), pre-operative hemodynamic instability (p=0.003) and international normalized ratio (INR) at admission (p<0.0001). As for post-operative preditors of outcome, hemodynamic instability in the ICU was statistically significant (p<0,0001). Binary logistic regression concluded elevated INR and post-operative instability were independent risk predictors of outcome (p<0.05). The mortality score prediction models aforementioned were applied to our population and estimated mortality significantly correlated with real mortality (estimated mortality 41% and 45.3% Vs real mortality 45%; both p<0.0001). Pearson correlation was applied to compare scores and concluded a correlation coefficient of 0.775 (p<0.001), describing a significant positive linear correlation between scores.
Conclusions: In recent years, EVAR has increasingly become the procedure of choice for rAAA in our institution. With this evolving approach to rAAA, both score prediction models were retrospectively applied and both accurately predicted mortality in the study population (p<0.001).


A method for manufacturing a semiconductor device forms a capacitor storage node contact of DRAM by a self-align method, forms a storage node contact simultaneously with a bit line contact, makes the storage node contact's depth be identical with the bit line contact's depth, and easily determines an etching target. The method includes the steps of: forming a transistor having a gate insulation layer(1), a gate electrode(2), source/drain area(3); forming a planarization layer(4) on the resultant material; simultaneously forming a bit line contact and storage contact by selectively etching the planarization layer(4); burying the bit line contact and storage node contact with a conductive material(16); forming the conductive layers(17,18) and an insulation layer(19) on the bit line contact, patterning them, and forming a bit line; forming a side wall insulation layer(20) on one side of the bit line; and forming a capacitor storage node(22) on a storage node contact.


Reverse-time migration is based on seismic forward modelling algorithms, where spatial derivatives are usually calculated by finite-differences or by the Fourier method. Time integration is in general done by finite-difference time-stepping of low orders. If the spatial derivatives are calculated by highorder methods and time-stepping is based on low-order methods there is an imbalance which may require that the time-step size needs to be chosen very small to avoid numerical dispersion. As a result computing times increase. Using the Rapid Expansion Method avoids numerical dispersion if the number of expansion terms is chosen properly. We show by comparisons with analytical solutions that the Rapid Expansion Method is preferable especially at larger propagation times. For reverse-time migration it may be desirable to use the Poynting vector information for estimation of opening angles to improve the image quality. In the solution of the wave equation this requires to calculate not only the pressure wave field but in addition its time derivative. We show that the Rapid Expansion Method can be easily extended to also provide this time derivative at negligible extra cost. INTRODUCTION The accuracy and efficiency of reverse-time migration strongly depends on the algorithm used for numerical seismic forward modelling. Both, the way in which spatial derivatives are computed as well as the kind of temporal time-integration affect the quality of the numerical results. Seismic modelling methods which are based on regular grids often use low order finite-difference (FD) time integration techniques. This applies for modelling algorithms where the spatial derivatives are calculated using finite-differences or by pseudo-spectral approaches like the Fourier method. If the approximations of spatial derivatives are calculated by higher order FD techniques or by the Fourier method there is an imbalance of the accuracies between the temporal and the spatial approximations. This can lead to unwanted numerical dispersion and hence inaccurate results for large propagation times (Dablain (1986), Crase (1990)). Kosloff et al. (1989) introduced the Rapid Expansion Method (REM) for solving the acoustic wave equation or the elastodynamic equations of motion with a source term and with zero initial conditions. This method has very high accuracy with respect to the temporal extrapolation. In fact the combination of the REM approach and the Fourier method allows to obtain modelling results which are free of numerical dispersion. The REM time integration basically starts from the formal solution of the governing partial differential equations and expands the solution into Chebyshev polynomials. This is much more efficient than using Taylor expansions. Since reverse-time migration (RTM) is based on seismic modelling algorithms it is desirable to also use a highly accurate numerical modelling approach for this purpose. Recently, Pestana and Stoffa (2009) described how to implement the REM approach in a time-stepping manner. For RTM this implementation is necessary since for the reverse modelling many sources with many different time-histories need to be applied at the receiver locations. This is incompatible with the original REM implementation of Kosloff et al. (1989) since in this approach the source must be separable in space and time. Therefore, Pestana and Annual WIT report 2010 187 Stoffa (2009) start from the formal solution of homogeneous differential equations. In this approach the samples of the time-reversed seismograms are used to modify the initial conditions time-step for time-step at the respective receiver locations. Pestana and Stoffa (2009) discuss the choice of the number of expansion terms by means of migrated images. To be on more solid ground to make a proper choice of the number of expansion terms in the present paper modelling results are compared to analytic solutions for simple geometries. Moreover, the computations of Chebyshev polynomials appears unnecessarily complicated in Pestana and Stoffa (2009). Moreover, the computation of Bessel functions is not appropriate since small arguments are assumed which is not always the case. A simple and accurate method to evaluate Bessel functions adopted from Abramowitz and Stegun (1972) is given in the Appendix A. In the first chapter a short review of the theory of time-stepping with the REM approach is given. In the second chapter 2D modelling examples are compared to analytic solutions for FD time-stepping as well as for the REM approach. Furthermore, it is examined how to chose the number of expansion terms to aim at modelling results which are free of numerical dispersion and truncation errors. In the third chapter it is shown that REM also allows to calculate first time derivatives of the solution of the wave equation. This is useful, e.g., in RTM when Poynting vectors need to be computed. The fourth chapter demonstrates the application of prestack RTM using the REM approach to a simple synthetic 2D example. Imaging results obtained by incorporation of Poynting vectors (Yoon et al., 2004) into the imaging condition are compared to images based on the full range of scattering angles. The last chapter summarizes the conclusions. SOLVING THE WAVE EQUATION BY THE RAPID EXPANSION METHOD WITH TIME-STEPPING The Rapid Expansion Method, first presented in Kosloff et al. (1989), solves the acoustic wave equation or the equations of dynamic elasticity with zero initial conditions. If these equations are written in an operator notation they read: ∂u ∂t2 = −Lu + f . (1) u and f denote the displacements and the source term, respectively. In case of, e.g., the 2D constant-density acoustic wave equation the operator −L is given by: −L = v ( ∂ ∂x2 + ∂ ∂z2 ) . (2) The quantity u in equation 1 is then replaced by the pressure p. v is the acoustic velocity. In case of variable-density acoustic modelling or elastic modelling the operator −L has a different form (see Kosloff et al. (1989)). u and f are vectors of size nx × nz , where nx and nz are the number of grid points in the respective directions. The operator −L is a n× n matrix, where n = nx × nz . The formal solution of (1) with zero initial conditions is: u(t) = ∫ t 0 sin L(t− τ) L f(τ) dτ. Here the source term needs to be separable in space and time, i.e., f(x, t) = g(x) h(t). (3) If we want to perform reverse-time modelling time-reversed seismogram sections need to be applied as sources. In this case the condition that the source is separable (equation 3) is not applicable since the individual seismograms all have different time histories. Therefore, we need to use the formal solution with non-vanishing initial conditions: u(t) = cos Lt u(0) + sin Lt L u̇(0), (4) 188 Annual WIT report 2010 where the dot denotes the time derivative. We also need to have the formal solution at time −t, i.e., u(−t) = cos Lt u(0)− sin Lt L u̇(0) (5) to eliminate the term with u̇(0). Here, we use the fact that the sin and cos functions are odd and even functions, respectively. Though u is a function of the position vector x and the time t for conciseness we dropped the spatial dependence. Adding equations 4 and 5 and solving for u(t) yields: u(t) = −u(−t) + 2 cos Lt u(0). (6) This allows to extrapolate the field u(t) from the fields u(−t) and u(0) at two previous time instances in a similar manner as known from finite-difference time-stepping. It remains to transform the formal solution into a form which can be solved numerically. In an analogous way to the expansion of the sin function in the formal solution with zero initial conditions in Kosloff et al. (1989) we can expand the cos function:

Modification of peptides to produce peptidomimetics is of great interest, with the aim of designing potent, selective, and metabolically stable analogs having certain conformational properties. Organoboranes have been reported in the literature with a wide range of therapeutic applications. One of the therapeutically important class of molecules is amine-carboxyboranes derived from amino acids by replacement of the C atom of an amino acid/peptide by boron. The conformational preferences of these peptides, with respect to backbone , , and torsion angles, have been investigated by theoretical calculations. The amide bond in these molecules has the same geometry in the ground and transition states as the natural peptides. However, the boron isosteres of glycine and alanine peptides are less structured than their natural derivatives, but are distinguished by structures with a positive value for the angle, which is normally disfavored for natural peptides. This property could be used to build peptides with a geometry not usually seen in natural peptides. Copyright © 2007 John Wiley & Sons, Ltd.

Investigation was conducted for all the blocks in the district of Nadia, West Bengal to estimate the over exploitation of ground water and to examine the possibility of mitigation of it through artificial ground water recharge. There were approximately 1.16 x 109 m3 irrigation water requirement except monsoon month (June to September) for rice cultivation. The estimated ground water recharge was found approximately 0.82 * 109m3. Thus, approximately 0.34 * 109 m3 of ground water was found over exploited every year if irrigation demands entirely satisfied through ground water. This 0.34 x 109 m3 of overexploitation could be mitigated if approximately 3.88 x 108m2roof top water harvesting structure along with the recharge facilities were created. The estimated cost for this purpose was approximately ` 666.488 billion. The creation of this facility may also contribute to large extent in domestic water supply along with the improvement of arsenic contaminated ground water of this district.

Pruritus was induced experimentally in a total of 13 non-atopic subjects and subjects with atopic dermatitis, and the effects of acupuncture on the symptoms of pruritus were investigated. Acupuncture needles were inserted around the itching points (wheals 25 mm from the point of the induced pruritus. Suppression of itch was reported in both groups after 1 min of acupuncture stimulation. The suppressive effect had disappeared by 5 min. This suppressive effect of acupuncture stimulation on pruritus was evanescent and non-disease- specific, and did not affect the other arm.


Increasingly, the nations of the world are becoming more interdependent among themselves. This is true not only in an economic sense, but in a political sense as well. The field of public administration has become internationalized, presenting a new challenge to both teachers and students of the discipline. The article argues that special attention should be given to teaching students how to manage policy interdependency. Furthermore, the interdisciplinary approach is advocated as a method of broadening students' perspectives in public administration. In concluding the article, the author offers several recommendations for improving public administration programs. Copyright 1989 by The Policy Studies Organization.

Discriminant analysis was used to classify 20 olive oil samples based on their near-infrared (NIR) spectra. The samples were successfully classified into two categories which are consistent with extra virgin olive oil and ordinary olive oil defined in the products. The NIR spectra of olive-oil mixtures containing colza oil, corn oil, peanut oil, camellia oil, sunflower oil, and poppy seed oil were collected, respectively. The volume percent of adulterants ranged from 0 to 100%. The best spectrum bands for analysis were selected before developing partial least-squares (PLS) calibration models. The relative errors of prediction ranged from -5.67% to 5.61%. Results showed that the method combined with chemometrics methods and near-infrared spectrometry is simple, fast and credible for qualitative and quantitative analyses of olive oil samples.


Sarcoidosis is a chronic inflammatory disorder of unclear etiology, characterized by the presence of non-caseating granulomas. Cardiac involvement occurs in upto 27 percent of patients, manifesting as atrioventricular blocks, ventricular arrhythmia or sudden cardiac death. Current guidelines cite insufficient evidence for the prognostic utility of positron emission tomography (PET) in patients with cardiac sarcoidosis. Thus, we performed a systematic review and meta-analysis of published studies to ascertain the prognostic significance of PET imaging in patients with suspected or diagnosed cardiac sarcoidosis.

 To review current literature and determine if PET has prognostic utility in patients with known or suspected cardiac sarcoidosis

 We performed a comprehensive literature search of electronic databases (Embase, Medline and Web of Science) using MeSH terms and keywords for sarcoidosis and PET from inception through December 2019. Studies were eligible if they included patients with known and/or suspected cardiac sarcoidosis undergoing evaluation by PET with or without perfusion imaging and reported clinical events of interest. An abnormal PET study was defined as the presence of focal or focal-on-diffuse uptake of 18- fluorodeoxyglucose (18-FDG) by visual analysis. In studies with perfusion imaging, patients with only perfusion defects were excluded. The primary outcome of interest was a composite of major adverse cardiac events (MACE), including sustained ventricular tachycardia, sudden cardiac death. Secondary analysis studied association of MACE with focal right ventricular (RV) uptake in patients with an abnormal PET study. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model. Heterogeneity of results among the studies was assessed using the Higgins I2 value.

 Out of a total of 1645 citations, 40 were selected for full-text review. Five studies were included in the final analysis with a total of 465 patients. mean follow-up was 2.3 years. Three of the five studies also reported frequency of abnormal RV uptake of 18-FDG. Patients with abnormal 18-FDG uptake on visual assessment had higher odds of MACE (OR 3.12, CI 1.9–5.01, p<0.00001), compared to known or suspected cardiac sarcoid patients with normal PET studies. Heterogeneity among studies was low (I2 = 0). In patients with an abnormal PET study, abnormal focal RV uptake of 18-FDG was associated with higher odds of MACE (OR 5.24, CI 1.1–25.1, p=0.04), with moderate heterogeneity among studies (I2=41).

 In patients undergoing PET imaging for known or suspected cardiac sarcoidosis, abnormal metabolism on visual analysis is associated with increased risk of MACE. Furthermore, focal RV uptake further increases the risk of MACE in patients with abnormal PET imaging. Thus, PET imaging can serve as a tool to risk stratify patients with known or suspected cardiac sarcoidosis.

We have fabricated photoconductors of indium nitride (InN) grown by radio frequency (RF) sputtering. The InN thin films were deposited on Si(100), Si(110) and Si(111) substrates at room temperature. The Ag/Al contact has been deposited by thermal evaporation in vacuum (10-5Torr) and then annealed under the flowing of the nitrogen gas environment in order to relieve stress and also induce any favorable reactions between metals and the semiconductor. Current–voltage (I–V) measurements after heat treatment at 400°C were carried out for samples in dark and illumination conditions. It was found that Ag/Al formed a good ohmic contact on top of InN. In addition, the characteristics of the contacts were significantly affected by the orientation of substrates.

A key to the identification of all known species from Costa Rica is given.


Objective To explore the underlying molecular mechanisms of estrogen induced apoptosis of synthetic vascular smooth muscle cells (VSMCs). Methods Cultured VSMCs on passage 3 were divided into three groups: 17β-estradiol (E-2) group, p38 inhibitor group (SB+E-2) and control group. With treatment for 72 hours,the apoptosis of cells was quantified by measuring the intracellular nucleosomes with ELISA; expressions of total p38, phospho-p38 and myocyte enhancer factor-2 (MEF2) were analyzed by Western blotting, with a confirmative immunohistochemical staining for MEF2. Results Compared with that of control cells, the rate of apoptosis in VSMCs grown in E-2 was significantly increased, with up-regulations of total p38, phospho-p38 and MEF2. These effects of E-2 were blocked in SB+E-2 group in which the rate of cell apoptosis and expression of p38 had no obvious change compared with that of control group, while the expression of p-p38 and MEF2 was decreased. Immunohistochemical staining showed that MEF2 was mainly located in cellular nucleus, and its expression was increased in E-2 group but decreased in SB+E-2 group. Conclusion Estrogen may induce apoptosis of synthetic VSMCs through p38 pathway-dependent up-regulation of MEF2.


The paper presents a case report of the patient with the maxillomandibular disproportion, treated with partial root− −retained overdenture. This kind of the anteroposterior disproportion was caused by a physiological gradual atro− phy of the alveolar ridge bone progressing with ageing. Due to this process, edentulous maxilla is retruding and the mandible circumference is increasing which may affect the prosthetic treatments results. In such cases, the use of partial overdentures allows this disproportion reduction and may diminish the atrophy of alveolar ridge. Also, a good aesthetic result of the treatment may be achieved. A mandibular partial overdenture was performed for the patient described in the paper. The abutment teeth were shortened to the gingival level and provided with root− retained Rhein'83 axial attachments. The matrix elements of the attachments were fixed in the overdenture. A com− plete denture was made for the edentulous maxilla. The chosen method of the prosthetic treatment allowed to achieve good aesthetic results avoiding surgical intervention. Moreover, good retention and stabilization of den− tures were achieved. The attachments provided axial transfer of the masticatory forces and decreased the traumat− ic effects on the denture−bearing tissues of the mandible (Dent. Med. Probl. 2008, 45, 3, 327–330).


We investigate the operation of a thin-film lithium niobite modulator with specific focus on the wavelength dependence. For a precise evaluation of the modulation distortion, we used an extinction-ratio-tunable-type modulator.


A method for recording respiration rates of attached single soybean pods is described. By means of such records source-sink relations can be observed over an extended period of time if photosynthesis of leaves is recorded simultaneously. It is shown that there are direct influences on respiration, such as changes in temperature and indirect effects which influence primarily the assimilate influx into the pods, e.g. light and competition between pods. The shading of a single leaf next to the pod has only a small effect because the pod is supplied by more than one leaf. By girdling the plants, the export-import conditions can be studied on a single leaf as source and a single pod as sink. The results show that a trifoliate fully-grown leaf produces more assimilate than can be used by a single pod. If only one pod is growing within the girdled area then starch is accumulated and the photosynthetic rate of the leaf is greatly reduced. The respiration rate of the pod is only slightly increased, in spite of the abundant availability of assimilates. It appears therefore, that the filling rate of pods is determined mainly by the capacity of the pod to off-load the phloem, and cannot be increased beyond a certain level by additional sucrose influx. Our results show that, using this method, the source-sink relations can be recorded qualitatively over time periods of 3-4 weeks.


A chemical gas-phase process capable to reduce the nitric oxide in diesel engine exhaust was studied. In this process, monomethylamine (CH 3 NH 2 ) was added to the exhaust gas in a molar ratio to NO varying between 1:1 and 4:1. Experiments were conducted in electrically heated quartz reactors in a temperature range of 200°C to 600°C. Diesel exhaust gas and simulated exhaust gas were used in this experiment. The results showed thorough mixing of methylamine into the exhaust effectively breaks NO down into nitrogen and water, enabling more than 80 percent NO reduction in a reactor temperature range of 400°C to 540°C and at a molar ratio of 1. On the other hand, imperfect mixing between methylamine and exhaust gases results in excess ammonia and reduced NO decomposition. Consequently, it is suggested that the mixing is a very important factor in this technique. The results also show that the coexisting gases such as carbon monoxide, carbon dioxide, hydrocarbons, and water vapor in the diesel exhaust have no effect on NO reduction by methylamine. However, the presence of oxygen in excess of 10 percent in the exhaust is needed for an 80 percent Nox reduction. Furthermore, the mechanisms of the methylamine process were discussed.


The statutory exceptions which relate to and bear upon the acts of agents and organs of government are examined along with the protections against liability for infringement of copyright that are afforded by the laws of parliamentary privilege, legislation concerning printing and publication of parliamentary papers, and freedom of information legislation. The various exceptions made in the Copyright Act 1968 recognize that there are public interests, which justify qualification of the exclusive rights of copyright owners.


The article reveals the socio-economic situation of the American society of the late XIX-early XX centuries, which objectively led to increase of the poor, contributing to the need for their financial support. The social services system in the United States began to emerge which was based on the experience of the UK and the ideas of social Darwinism and socially oriented philanthropy. The article reveals the peculiarity of American charity, which consists in the fact that it was built from the perspective of two approaches: social-reformist and individually oriented, which is described on the example of Mary Ellen Richmond. The model of the USA social work is developed (early twentieth century) with the rationale of the three stages – organizational-legal, philosophical-utopian, organizational-educational, each of which dominated one of the basic entities – the government, charitable organizations or social workers who engage in relationship with those in need. The article presents the views of M. Richmond, connected with the professional education of social workers, their innovation and scientific nature. Structurally functional model of social partnership is developed on the basis of spiritual ontological approach. The main innovative components of the social work and their interaction is described, namely: subjects, from friendly visitors to professional social case workers; rigorism values-goals embodied in the plans for the moral correction of the poor; innovative values-means including case work, social diagnosis, the diagnosis of the client, etc.


This paper has studied the feasibility of detection of crack development and plastic deformation on pressure vessel based on magnetic memory test.The tensile specimen was made of 16MnR steel,which is always used in pressure vessels.Several cracks in directions of uprightness and parallel were pre-made on them,and then some tensile experiments were done on the material test machine.The magnetic signals were detected by magnetic memory sensors to research different variation of magnetic signals on different tensile stage.The ferromagnetic theory was used to explain the variation.In order to characterize the plastic strain of pressure vessel steel,a load gradient parameter was put forward based on the analysis of tensile load changes and magnetic signal changes.

This article deals with the Chua's circuit characterization from the point of view of a filter based on the concept of piecewise linear functions. Furthermore, experiments are developed for teaching electronic systems that can be used for filtering. The frequency range, in which is tested, is from 20Hz to 20kHz, due to audio spectrum is comprised in this frequency range. The associated node to the capacitor and Chua's diode is used as input, and the node comprised for the another capacitor and the coil is used as output, thereby establishing one input-output relationship for each system case given by the piecewise linear functions. The experimental result shows that Chua's circuit behaves as a bandpass filter-amplifier, with a maximum frequency around 3kHz and bandwidth between 1.5kHz and 5.5kHz. Submitted to: Eur. J. Phys. ‡ Corresponding author Chua's circuit and its characterization as a filter 2

The indentation of standard viscoelastic solids, that is, the three-element viscoelastic material, by an axisymmetric, flat-ended indenter has been investigated theoretically. Under the boundary conditions of flat-punch indentation of a viscoelastic half-space, the solutions of the equations of viscoelastic deformation are derived for the standard viscoelastic material. Their generality resides in their inclusion of compressible as well as incompressible solids. They cover the two transient situations: flat-punch creep test and load-relaxation test. In experimental tests of their applicability, nanoindentation and microindentation probes under creep and relaxation conditions yielded a modulus from 0.1 to 1.1 GPa and viscosity from 1 to 37 Gpa · s for a crosslinked glassy polyurethane coatings. For bulk polystyrene, the values vary from 1 to 2 GPa and from 20 to 40 Gpa · s, respectively. The analysis here provides a fundamental basis for probing elastic and viscous properties of coatings with nanoindentation or microindentation tests. © 2000 John Wiley & Sons, Inc.

The analysis of the tolerances on the power pattern of an array of electromagnetic radiators having excitation amplitudes affected by random errors around the nominal values is addressed. Toward this end, an analytic strategy based on interval analysis is exploited to predict the bounds of the variations in the radiated power pattern in correspondence with difference models of the amplitude tolerances. Selected results are presented and discussed in a comparative fashion as well.


This work is focused on syntax error recovery, a complex aspect of syntax analysis. We have enhanced a parser visualization tool called VAST to produce educational visualizations of this topic. Compiler visualization is not a new research field, but the authors have not found any visualization tool dealing with this topic. We have evaluated the enhanced version of VAST and its visualizations about syntax error recovery strategies. We have detected that students who used the enhanced tool improved their performance developing syntax specifications with error recovery. Consequently, these students significantly improved their learning outcomes regarding error recovery exercises.


This study was conducted to investigate the influence of extraction conditions i.e. water:fronds ratio (0.5:1 – 12:1), temperature (25 – 90 ̊C) and pH (3 – 11) on extraction yield, crude protein content and emulsifying capacity of mucilage from Talinum paniculatum fronds. Response surface methodology with a face cantered-central composite design was applied to optimize the extraction conditions. With 20 experimental runs, extraction yield, crude protein content and emulsifying capacity of the mucilage were recorded to be 2.32 – 4.90%, 15.05 – 30.97% and 8.05 – 37.93%, respectively. Response surface analyses showed that increases in mucilage yield were mainly due to significant (p < 0.05) quadratic effect of pH and also synergistic effect between water:fronds ratio and pH. In contrast, significant (p < 0.05) quadratic effect of temperature and its synergistic effect with water:fronds ratio led to increase in emulsifying capacity of the mucilage. Furthermore, linear effect of pH seemed to significantly (p < 0.05) increase the crude protein content, in addition to significant (p < 0.05) synergistic effect between water:fronds ratio and pH. Experimental data for each response were best fitted with a quadratic model, having high coefficients of determination (R = 0.81 – 0.98) and no lack-of-fit. The optimum conditions for mucilage extraction from T. paniculatum were obtained at water:fronds ratio of 8.4:1, temperature of 90 0C and pH of 8, providing 3.44 % yield, 29.35 % crude protein content and 34.00 % emulsifying capacity of T. paniculatum mucilage.


The phase transition of crystalline in poly(vinylidene fluoride) fromαanti-ferroelectric toβferroelectric phase achieved by electric poling treatment with a high temperature has been investigated. It was found that the ferroelectricity of polymer was improved and the polarization depended on increasing poling electric field was non-linear.The phase transition of PVDF in electric field was theoretical simulated based on dynamical equilibrium.The results show that the effective electric field affected on the crystalline is 50 MV/m,which accords with the coercive field of ferroelectric PVDF.At the same time,the effective electric field affected on the amorphous is close to starting electric field of the phase transition.It demonstrates that the method of dynamical equilibrium simulated phase transition of crystalline in PVDF is feasible.

The study aims to substantiate the methodology for assessing the sustainable development of sports and health in the region. To achieve this goal, the following tasks are necessary: to reveal the essence of the sports and health sphere of the region; determine the role of sport in achieving sustainable development goals; substantiate the need for a comprehensive analysis of sustainable development of sports and health in the region; to develop a methodology for assessing the sustainable development of sports and health in the region. The article defines the essence of the sports and health sphere of the region. Over the past two decades, sport and other forms of physical activity have been found to be used to achieve social development goals and as a tool for peacekeeping and peacekeeping operations around the world as part of the so-called "sport for development and peace". The main international documents declaring the importance of sport in achieving development and peace are presented. It is proved that the effective functioning of the sports and health sphere of the region in the complex ensures the achievement of economic, social, and health goals, which meets the guidelines of sustainable development. The legislative bases of sustainable development of physical culture and sports in Ukraine are revealed, the main tasks and ways of activation of sustainable development of sports and health sphere in Ukraine under the conditions of decentralization are given. It is argued that determining the effectiveness of measures to enhance physical culture, sports, and health in the regions in order to timely adjust the policy of local governments to support it requires systematic monitoring of sustainable development of sports and health. On this basis, the need for comprehensive analysis is substantiated and a method for assessing the sustainable development of sports and health in the region has been developed. The use of this technique provides opportunities to identify the achievements and problems of the development of mass sports for the application of relevant state institutions, the specification of measures aimed at the development of physical culture, sports, and health.


Our knowledge about the nature and biological activity of tumor cells residing in the prostate gland after radical radiotherapy (RRT) is limited.


In this research an experimental study was conducted to explore some mechanical properties such as compressive strength and splitting tensile strength and modulus of elasticity of concrete mix with weighted mixed portions (1 : 1.5 : 2 / 0.35) reinforced with polypropylene fibers by (0.25%, 0.50%, 0.75%, 1.0%, 1.25%) as volume percentage comparing with normal concrete. Research also contain testing modulus of rupture and maximum deflection of polypropylene concrete beams with dimensions (100×100×500) mm with the same volume percentage and concrete beams with half depth fibrous concrete and the other half normal concrete and comparing with the modulus of rupture and maximum deflection of normal concrete beams.


The incorporation rates of growth units into kink sites on growth surfaces of crystals by series processes via intermediate sites from solution are investigated by changing the energy states of the intermediate sites and the activation energies for the processes. A simple model where the activation energies are proportional to the differences of the energy states between sites is taken in the present study to illustrate the concept. The model shows that the incorporation rate of a series process via an intermediate site in a certain energy state becomes much larger than those via intermediate sites in different energy states, suggesting the existence of a rapid-incorporation path in surface kinetics of crystal growth.


It is shown that the elastic strain fluctuations are a direct measure of elastic compliances in a general anisotropic medium; depending on the ensemble in which the fluctuation is measured either the isothermal or the adiabatic compliances are obtained. These fluctuations can now be calculated in a constant enthalpy and pressure, and hence, constant entropy, ensemble due to recent develpments in the molecular dynamics techniques. A calculation for a Ni single crystal under uniform uniaxial 100 tensile or compressive load is presented as an illustration of the relationships derived between various strain fluctuations and the elastic modulii. The Born stability criteria and the behavior of strain fluctuations are shown to be related.


Experiments were conducted to study the effect of magnesium–aluminum alloy on the combustion performance of hydroreactive fuel propellants. The raw metal powders added to the propellants were ball-milled magnesium–50% aluminum alloy (m-AM), magnesium–50% aluminum alloy (AM), and Al and magnesium (Mg) powders, which were characterized using scanning electron microscopy, X-ray diffraction (XRD), and simultaneous thermogravimetric analysis (TGA). A high-pressure combustor and a metal/steam reactor were used to simulate the two-stage combustion of hydroreactive propellants used for a water ramjet. The combustion performance of the metal powders in propellant was studied experimentally, and the efficiency of the Al reaction in the propellants during the two-stage combustion was calculated. TGA traces in air indicated that the oxidation onset temperature of AM powders is much lower than for both Mg and Al powders. The XRD patterns for the AM and m-AM alloys exhibited Al12Mg17 diffraction peaks. The hydroreactive fuel propellant systems with added m-AM powder exhibited good performance in terms of burning rate, combustion heat, and the Al reaction efficiency, which was better than that for the propellants containing AM, Mg, and Al powders. At the pressure studied (3.0 MPa), the burning rate of the m-AM-containing propellant was found to be 15 mm s−1, and the heat of primary combustion was 6,878.1 kJ kg−1.


Objective: This systematic review aimed to determine the prevalence of neuropsychiatric symptoms in COVID-19 and post-COVID-19 patients in Southeast Asia and explore associated factors. Methods: Following PRISMA guidelines, a comprehensive literature search was conducted in relevant databases. Studies reporting on the prevalence of neuropsychiatric symptoms such as fatigue, anxiety, depression, sleep disturbances, cognitive impairment, and post-traumatic depression in COVID-19 and post-COVID-19 patients in Southeast Asia were included. Data were extracted and analysed to determine the prevalence rates and associated factors. Results: A total of 7 studies met the inclusion criteria. The findings revealed a high prevalence of neuropsychiatric symptoms among COVID-19 patients in Southeast Asia. Fatigue was reported by approximately 43.3% of patients during active COVID-19 infection and 45.1-54% in the post-COVID-19 phase. Anxiety affected 14.3-28.1% of COVID-19 patients, with comorbidities and severity being closely associated. Depression was prevalent in 3.6-38.7% of COVID-19 patients, with healthcare workers showing a higher prevalence. Sleep disturbances were reported in approximately 16.1% of post-COVID-19 individuals. Various factors such as age, gender, quarantine duration, and socioeconomic status were identified as potential contributors to these symptoms. Conclusion: Neuropsychiatric symptoms, including fatigue, anxiety, depression, sleep disturbances, cognitive impairment, and post-traumatic


In order to meet the requirements of image retrieval and real-time index storage of massive datasets, a Content-based Image Retrieval (CBIR) based on vector quantization is used in this paper. By the feature extraction of depth residual network, the improved Product Quantization (PQ) coding algorithm is used to generate index and dynamic database under FAISS Framework, which can realize nonlinear large-scale CBIR with high robustness. Empirical results show that the CBIR based on improved PQ has achieved good performance in index compression rate, recall rate and retrieval time compared with PQ and Locality-Sensitive Hashing (LSH) in SIFT1M dataset.


A relaxation iterative method is suggested for variational inequalities whose basic operator is the sum of a single- and a multi-valued operator. The parameters of the method are chosen by iteration of the generalized splitting technique. The method is proved to converge in the case of monotone operators. Linear convergence of the method is established under additional assumptions.


Statistical education and training at tertiary level encompasses a very wide range of actives. There are the short "service" courses for students studying, say, engineering or medicine or politics (often of just 10 or 20 hours providing testing or regression) often nowadays linked to some computational software system. At the next level we encounter in some disciplines such as agriculture, economics or social science, a number of "designer" courses spanning a fair proportion of the study time, perhaps up to one third of the overall programme. Finally, there are full statistics programmers for students of statistics per se (or mathematics programmes oriented to non-deterministic mathematics) where most of the study time is spent on the concepts, methods and practice of probability and statistics, with the inevitable supporting coverage of relevant mathematical material.


The application of horticultural therapy to prison and jail populations has received little evaluation. The resulls of baseline interviews with 57 San Francisco County jail inmates randomly assigned to a horticultural therapy program are presented. An ecological analysis of the inner city jail population identifies the relationship between job loss, family disintegration, and history of victimization. The role of trauma in precipitating self-framentation is explored with respect to the high incidence of drug abuse and illegal activities. The use of nature to promote healing and growth is discussed. The importance of empathic interventions by the horticultural therapist is noted.


For several years operational reconnaissance films have been annotated with flight, data digitized in the format of MIL-STD-782 code blocks. It is almost universally accepted in the using services that a code block annotated. on film permanently, visibly, and in direct. association with the pertinent photo imagery-is a long term, continuing, requirement. For over a year, Fairchild Hiller Corporation conducted., a substantial company-funded effort to fully explore all aspects of reading. This work resulted in contracts for a feasibility model. from the Photo Management office of the Naval Air Systems Command, and later for a produc-tion design from the Tri-Service TIPI SPO. The need for automatic re.Hders of the code block is a direct result of the large volume of film being handled. Equipments such as motorized light tables, computer aided mensura tion systems, continuous process film titters and route-and-coverage plotters all will benefit from the use of compact, reliable, error free,. high speed code block readers. -

A six week land-based survey was conducted at Pt Lookout on the east coast of Australia, in June and July 2007. Over the peak four weeks of the northward migration, an average of 70.7 whales passed per 10h. This was compared with a similar metric from previous surveys at this site yielding a long-term rate of increase of 10.9% per annum (95% CI 10.5 – 11.4%), slightly higher than our previous estimate from a survey in 2004 (Noad et al., 2006). This indicates that the long-term rapid increase in the size of the east Australian population of humpback whales continues without any apparent slowing. Aerial surveys were also conducted concurrently with the land-based surveys during which 249 groups of humpbacks containing an estimated 399 whales were seen from the air. Analysis confirms that only about 3% of groups pass more than 10km of the headland which is consistent with Bryden's (1985) estimates despite an approximately 15-fold increase in the population over this time. Further, the offshore distribution of whales was characterised with no significant difference being found between the patterns of distribution whether measured from land or air. Approximately 89% of groups passed within 5km of land and the mean distances offshore for both aerial and land-based surveys were less than 2.5km. This supports one of the key assumptions of the land-based counts, that they are not greatly affected by whales missed as a function of increasing distance offshore. An estimate of absolute abundance for 2007 was made by extrapolating from the 2004 absolute abundance estimate. Using the land-based correction factor for groups available but missed estimated in 2004, 2007 absolute abundance is estimated at 9,683 whales (95% CI 8,556 – 10,959).


This paper considers the design of smooth state feedback controllers to track periodic solutions of control affine nonlinear systems. The objective is to show that stabilization of desired periodic solutions can be achieved by tracking a periodic reference signal using time-dependent damping feedback. The approach consists in computing an expression for a locally defined time-varying dissipative potential for the error dynamics. Following the Jurdjevic-Quinn approach, the obtained potential is then used to construct a smooth feedback controller that asymptotically stabilizes the system to the desired periodic invariant set. A numerical application to a Lotka-Volterra system is presented to illustrate the construction.


ANTHRAX SEQUENCESeven months after anthrax letters hit U.S. media and government offices, investigators still haven't nabbed a suspect--and the genome project launched in part to help them seems unlikely to provide a break either. An analysis of the genome of the strain used in the attacks, published online this week by Science ([www.sciencexpress.org][1]), has yielded extra tools for fingerprinting the hundreds of different anthrax strains, but little in the paper suggests that it can help the FBI tie the attack strain to a specific lab.

While traveling in Europe as a journalist,Zeng Qi(1892-1951) had made a comparison about the differences of national defense between China and the western countries.Considering the reality in China and the possible threats of war in the future,he had put forward such thoughts on national defense as making affluent battle planes and submarines;strengthening education of national defense on military personnel and civilians;and watching out for Japan and going against the Soviet Union.There are enough shortcomings because of his class attitudes and limitations in knowledge,but there is still something that we can learn from his thoughts on national defense.


We investigate quantum inspired algorithms to compute physical observables of quantum many-body systems at finite energies. They are based on the quantum algorithms proposed in [Lu et al. PRX Quantum 2, 020321 (2021)], which use the quantum simulation of the dynamics of such systems, as well as classical filtering and sampling techniques. Here, we replace the quantum simulation by standard classical methods based on matrix product states and operators. As a result, we can address significantly larger systems than those reachable by exact diagonalization or by other algorithms. We demonstrate the performance with spin chains up to 80 sites.


This paper analyzes primary qualitative evidence from life histories of rural capi- talists in contemporary Senegal. Various common themes in the declining literature on rural capitalism in Africa are discussed with reference to the specific individual trajectories of rural farm capitalists in Senegal. The themes include the emergence of rural capitalism in the context of protracted, uneven and gradual rural social differentiation and the various processes that have accompanied it; the condition of 'entrepreneurship' in such changing historical contexts; the symbiotic relation- ship between different spaces (loci) of accumulation, especially trade, transport and farming and the historical context in which they take place; the crucial but sometimes contradictory role of the state in spurring or constraining rural capitalist accumulation; and the variety of 'idioms of accumulation', which reflect tran- sitions and synthesis between non-capitalist and capitalist forms of labour surplus appropriation at the level of individual capitalists, despite some uniformity in the general logic of capital and the spread of capitalist relations of production and exchange. The paper also discusses the methodological power and limitations of oral narratives as a method to gather evidence on long-term processes of agrarian change and accumulation in rural Africa. Finally, the life histories shed some light on the origins of rural capitalists and show that there is a combination of instances of 'capitalism from above' and 'from below' but that no dominant pattern can be clearly discerned at least in the space of one or two generations.


Myocarditis is defined as an inflammation of the heart muscle and its presentation, especially in athletes, is heterogeneous. Underlying causes include in most of the cases viruses, and less often bacteria, toxins, vasculitic diseases or pharmaceutical agents. Cardiac magnetic resonance (CMR) imaging is the primary imaging tool to diagnose myocarditis following laboratory test, electrocardiogram and echocardiography. In certain cases, endomyocardial biopsy is required, especially in unclear cases with reduced systolic left ventricular ejection fraction. Although, athletes and sport physicians face the dilemma of significant performance decline in competitive athletes against the risk of adverse cardiac events, currently abstinence from competitive sports is recommended for at least 3–6 months in myocarditis. Sports recommendations are currently based mainly on autopsy studies and experts' opinions and better risk stratification tools are imperatively needed. New tissue characterization methods, namely T1 mapping and T2 mapping in CMR continue to improve sensitivity and specificity of diagnosing myocarditis and may further enhance individual risk assessment. In the future, sports physicians may be able to rely more on these novel noninvasive tissue characterisation methods in risk stratification and sports restriction recommendations of athletes with suspected myocarditis.


According to the development of Japanese sewerage engineering,the necessity and function for sewerage engineering are presented.It is proposed that sewerage engineering is the basis of ecological environmental protection and construction as well as landscape and graceful engineering.It must be prior to developing sewerage engineering undertaking.


For more than two centuries, landscape design in Western culture has been considered a matter of creating visual imagery, usually divorced from any concept or understanding of natural process. This view has often resulted in landscape forms that lack roots in the earth and are therefore shallow in character. The ecological understanding developed over the past several decades makes it clear that in nature the landscape we see is the visible manifestation of underlying, ongoing processes. Form and process are inseparable. For landscape design to be truly meaningful, it should also give visible expression to the processes that shape the earth, thus making a connection between nature and human culture. Landscapes that accomplish this can be described as having deep forms.


Background Beta-lactamase genes are one of the most important groups of antimicrobial resistance genes in human and animal health. Therefore, continuous surveillance of this group of resistance genes is needed for a better understanding of the local epidemiology within a country and global dissemination. Aim This review was carried out to identify different beta-lactamase resistance genes reported in published literature from Nigeria. Methods Systematic review and meta-analysis was carried out on eligible Nigerian articles retrieved from electronic literature searches of PubMed®, African Journals Online, and Google Scholar published between January 1990 and December 2019. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was adopted to facilitate clarity and transparency in reporting review findings. Results Fifty-seven articles were included. All beta-lactamases reported were detected from Gram-negative bacteria, particularly from Enterobacteriaceae. Thirty-six different beta-lactamase genes were reported in Nigeria. These genes belong to the narrow-spectrum, AmpC, extended-spectrum and carbapenemase beta-lactamase resistance genes. The pooled proportion estimate of extended-spectrum beta-lactamase genes in Nigeria was 31% (95% confidence interval [CI]: 26% – 36%, p < 0.0001), while the estimate of the blaCTX-M-15 gene in Nigeria was 46% (95% CI: 36% – 57%, p < 0.0001). The proportion estimate of AmpC genes was 32% (95% CI: 11% – 52%, p < 0.001), while the estimate for carbapenemases was 8% (95% CI: 5% – 12%, p < 0.001). Conclusion This study provides information on beta-lactamase distribution in Nigeria. This is necessary for a better understanding of molecular epidemiology of clinically important beta-lactamases, especially the extended-spectrum beta-lactamases and carbapenemases in Nigeria.


To make BNT-BT ceramics, in this study, we put amount of small BaTiO3 (BT) which has the characteristics of the ferroelectric and the tetragonal structure at the normal temperature in BNT. The temperature goes up very fast to the maximum, 100degC for first 3 minutes and then it is saturated. We can recognize from the P-E curve that much more generation of heat is accompanied the impressed electric field increases. This is natural because as the thermal loss is proportioned to the square of electric field in case of regular resistance if the electric field goes up. Therefore, in this study, we show the heat-generation phenomenon and temperature stabilization of the BNT-BT ceramic which can be used as a reference to develope better BNT-BT ceramic.


We report electron paramagnetic resonance (EPR) spectroscopy of a small ensemble of spins using a single nitrogen-vacancy (NV) center in diamond. We first identify a single NV center using fluorescence and optically detected magnetic resonance spectroscopy, then demonstrate double electron-electron resonance (DEER) spectroscopy to perform EPR detection of surrounding spins. Through the EPR spectrum analysis, we determine that the detected spins are nitrogen impurities in diamond. Moreover we estimate the number of the detected spins to be a few tens of spins using simulation of the DEER signal.

Fatigue may be among the most profound and debilitating consequences of pediatric traumatic brain injury (TBI); however, neurostructural risk factors associated with post-injury fatigue remain elusive. This prospective study aimed to evaluate the independent value of susceptibility-weighted imaging (SWI) biomarkers, over-and-above known risk factors, to predict fatigue symptom severity in children with TBI. 42 children were examined with structural magnetic-resonance imaging (sMRI), including a SWI sequence, within 8-weeks post-injury. The PedsQL Multi-Dimensional Fatigue Scale (MFS) was administered 24-months post-injury. Compared to population expectations, the TBI group displayed significantly higher levels of general fatigue (Cohen's d = 0.44), cognitive fatigue (Cohen's d = 0.59), sleep/rest fatigue (Cohen's d = 0.37), and total fatigue (Cohen's d = 0.63). In multi-variate models adjusted for TBI severity, child demographic factors and depression, sub-acute volume of SWI lesions was independently associated with all fatigue symptom domains. The magnitude of the brain-behavior relationship varied by fatigue symptom domain, such that the strongest relationships were observed for the cognitive fatigue and total fatigue symptom scales. Overall, we found that total volume of SWI lesions explained up to 24% additional variance in multi-dimensional fatigue, over-and-above known risk factors. SWI has potential to improve prediction of post-injury fatigue in children with TBI. Our preliminary findings suggest that volume of SWI lesions may represent a novel, independent biomarker of post-injury fatigue scores, which could help to identify high-risk children who are likely to benefit from targeted psychoeducation and/or preventive strategies to minimize risk of persisting fatigue.


Aim: The aim of this study was to determine the serum/plasma levels of zinc, vitamin C and E in male subjects with type 2 diabetes mellitus to establish their concentration pattern. Place and Duration of Study: Medical outpatient clinic, Chemical Pathology Laboratory of Enugu State University of Science and Technology Teaching Hospital, between January and December 2016. Methodology: This prospective cohort study enrolled 40 male individuals with type 2 diabetes mellitus and 40 apparently healthy control, within the age range of 45-75 years. Zinc, vitamin C, vitamin E, and fasting blood glucose levels were determined at pre-treatment, six months and 12 months into treatment. Results: The mean values of zinc, vitamin E and fasting blood glucose were significantly higher at pre-treatment compared to apparently healthy control values (147. 76 +/32.95 vs 114.31+/15.58 μg/dl, 11.88 +/3.13 vs 3.42 +/0.21 mg/dl and 8.08 +/3.22 vs 5.25+/0.35 mmol/l respectively) Original Research Article Ifeanyichukwu and Ngwu; IJTDH, 40(3): 1-5, 2019; Article no.IJTDH.54560 2 (p=<0.001, <0.001, and <0.001 respectively). At 6 month into treatment in comparison to pretreatment values, there were significant decreases in vitamin C (3.90+/-0.97 vs 5.15+/-1.43 mg/dl) (p= 0.04). At 12 month into treatment in comparison to pre-treatment values, there were significant decreases in vitamin C (3.25+/-0.16 vs 5.15+/-1.43 mg/dl) (p= <0.001). At pre-treatment, vitamin C significantly decrease from 6.49 +/0.96 mg/dl in age group 45-64 years to 4.10 +/0.76 mg/dl in age >65 years (p=0.01). Conclusion: The levels of vitamin C were lower at six months, but lowest at 12 month into treatment. Also vitamin C levels were found to be lower in age >65 years.


ABSTRACT Lo's variation theory is a learning and teaching theory based on Marton's phenomenographic approach and is one of the most important backbones of learning studies. The proponents of variation theory demarcate their approach from constructivist learning approaches, stressing constructivism as philosophical framework, but not as learning theory. At the same time, the phenomenographic approach emphasizes the importance of Piaget's work about the cognitive development, which should be considered when talking about learning and teaching. We argue that – from a theoretical point of view – Piaget's theory of how cognitive schemata are developed and how variation theory proposes that learning can be fostered entails many similarities which are not apparent at first glance. We demonstrate the similarities and differences using a teaching example from an English as second language classroom and show the implications for practical instructional work. Finally, we discuss concrete suggestions how variation theory could benefit even more from Piaget's theory.


A seismic reflection profile, perpendicular to the ice flow direction has been acquired on Rutford Ice Stream, Antarctica. An interpretation of both the amplitude and phase of the seismic reflections from the ice-bed interface has been made to investigate the properties of the sub-ice material. The interpretation assumes that acoustic impedance can be used to imply subglacial sediment porosity. Multiple reflections from the ice-bed interface on a number of seismic wide-angle lines allowed a calibration of the reflection coefficient at the bed. This enabled the acoustic impedance of the bed material to be calculated from the seismic reflection data. Mean acoustic impedance in the different sections of the bed ranges from 2.70×106 kg m−2 s−1 to 4.31×106 kg m−2 s−1. Almost three quarters of the ice stream bed at this site appears to be saturated, deforming sediments. The rest of the bed is probably also saturated sediments, but they are not deforming to any significant degree. Ice flow could include a combination of subglacial deformation and basal sliding. Localized regions which support disproportionately high amounts of basal shear stress may also occur. From the seismic data, it is not possible to apportion relative amounts of restraint to these different processes. There does not appear to be any correlation between the different sections identified on the ice stream bed with either satellite images or nearby surface velocity data. A feature which is interpreted as a subglacial drumlin is seen on the seismic section.


The Peatland Smouldering and Ignition (PSI) model was developed to quantify the heat transfer from a wildfiretoan organic soilormosssurface inaSphagnum-blackspruce peatland. TheCanadianFireBehaviour Prediction system was used as a basis for the relationship between wind speed and rate of spread. Convection, conduction, and radiation processes were modelled before and during the arrival of the flaming front. The net heat flux to the soil from fire varied between 1.1 and 8.6MJm � 2 , with moderate-intensity fires transferring more energy to the surface compared with higher-intensityfiresunderhigherwinds.Radiativeheattransfertothesoilsurfacebothbeforethefire'sarrivalandwithin the flaming front were the primary mechanisms of energy gain to the peatland surface. The role of convective and conductive cooling was no greater than 30% of gross energy gain. Peatland surface ignition in hummock and hollow microforms was modelled under normal and drought conditions. Hollow microforms dried out significantly during the course of a summer and increased their ignition vulnerability. Small-scale changes in slope and aspect of the peatland surface increased the amount of heat transferred by radiation by up to 30%, allowing some areas of higher soil moisture content to ignite. While no direct model validation is available, model outputs showing the preferential combustion of lichen and feathermoss, and the lack of ignition in Sphagnumin all but the most severe drought generally mimic observed ignitionspatterns. The modelledpeak of net energy input tothe surface occurred at moderatewind speeds, suggestingthat high-intensity fires do not necessarily lead to greater energy transfer and risk of smouldering combustion.


This paper proposes a new fuzzy-logic-inspired multi-contrast-agent strategy (MCAS) for optimal tumor classification. The proposed strategy accounts for the competitive and symbiotic relationships among multiple contrast agents through a sequential logic circuit analysis. Furthermore, the strategy enables an intuitive yet systematic way to analyze the tumor classification vagueness and ambiguous uncertainties and optimize the utilization of multiple agents through a fuzzy comprehensive evaluation. A numerical example is used to demonstrate how the classification performance in terms of decision-making fuzziness is significantly improved with an optimal "cocktail recipe" methodology using the proposed MCAS.


Like other visible characteristics such as skin color, gender, or age, body size is a diffuse status characteristic that impacts perceptions, interactions, and social outcomes. Studies demonstrate that individuals hold preconceived notions about what it means to be fat and document a long list of negative stereotypes associated with fat individuals, including laziness, unintelligence, and incompetence. Such perceptions have consequences for employment, including decisions about hiring, promotion, compensation, and dismissal. In this article, we examine how body size and race interact to affect individuals' perceptions of success, competence, health, laziness, and masculinity. Based on undergraduate students' ratings of photographs of men, our findings demonstrate significant differences between evaluations of black and white men based on body size. Thin white men are perceived to be more intelligent, more successful, and more competent than their thin black counterparts. However, these results reverse when the men are overweight: overweight black men are seen as more intelligent and more competent than overweight white men. They are also seen as more successful and hardworking and more masculine. These results suggest that the stigma of body size differently impacts black and white men; individuals judge overweight white men more negatively than overweight black men. We discuss two possible explanations for these findings: black threat neutralization and race-based attribution theory.


Mathematical modeling of thermal responses allows testing of wide performance limitations in individuals exposed to environmental extremes. One important application is in the determination of hazard materials (HAZMAT) workers' endurance times to execute a task. The simulation approach is especially important when operational settings with such individuals are restricted to finite thermal limits necessary to protect the individual. In essence, the ideal mathematical model of thermal strain (both heat and cold stress) should incorporate all essential variables active in thermoregulation. Although almost an insolvable task, a great many worthwhile models do a reliable job describing the heat balance equation. Models are quite useful in a first approach prediction of physiological effector response (sweating rate, skin blood flow, etc.), particularly when a given metabolic activity stays constant over the time of the given exposure. Early forerunners of rational thermal models employed elements of heat exchange that predict physiologic response and incorporate extensive descriptions of the passive system in terms of a steady-state bio-heat equation. In our Institute, a significant database has been collected from human experimental studies and wide clothing systems by which predictive modeling equations can be developed for individuals working in various environments. One model developed takes into consideration different clothing ensembles, varied levels of aerobic fitness in a population, and effects of progressive dehydration to heat stress/exercise. This review encompasses approaches conventionally used in both rational and operational models and presents a comparison between measured and predicted core temperature responses during exercise and environmental exposure often encountered during HAZMAT operations.

Once again retained austenite as one component of the microstructure of quench hardened steels is the basis for discussion among experts. Very often the thermic stabilization of retained austenite is the focus of interest. In this paper the influence of aging on the effectivity of retained austenite transformation by refrigeration (subzero cooling) is discussed, with aging taking place in a low temperature and a short time field between the end of quenching from different austenitizing temperatures and starting the subzero cooling. Results which are typical for tool steels are presented and the influence of the Si-content on the thermic stabilization of retained austenite is discussed.

This dissertation describes the evolution of the different local magnetic field generating systems for independent actuation of multiple microrobots. A description of the developed hardware, system characterization tests, and experimental results are presented. The system is designed for automated control of multiple microrobots. Finally, sample micromanipulation tasks are demonstrated using the new microrobot design, showcasing its improved manipulation capabilities.First, a mm-scale local magnetic field generating system designed for single layer coils is used to control 3.175 mm size N52 magnets as robots independently in the workspace. The controller used a set of local equilibrium points that were generated from a sequence of coil currents around the robots from one state to the next. The robots moved along paths computed through optimal control synthesis approach to solve complex micromanipulation tasks captured by global LTL formulas. However, the use of local equilibrium points as the states limited the motion of the robot in the workspace to simple tasks. Also, the interaction between the robots limited the robots to stay within far distances with each other. Hence a larger workspace based coil is designed to actuate up to four mm-scale robots in the workspace.To improve the resolution of motion of these robots in the workspace, the mm-scale coils are modeled extensively. The forces generated by various coil combinations of the array are modeled and solutions for different actuation force directions are discovered for different locations in the coil. A path planning problem is formulated as a Markov decision process that solves a policy to reach a goal from any location in the workspace. The MDP formulation is also expanded to work when other robots are present in the workspace. The formulation considers the interaction force between the robots and changes the policy to reach the goal location which reduces in the uncertainty of motion of the robot in the presence of interactions from other robots in the workspace.The mm-scale coils are difficult to scale down for microrobotic applications and hence a new microscale local magnetic field system was designed. A new microscale local magnetic field system which consisted of two 8 × 8 array of coils aligned in two axes in two layers of a PCB was designed which could actuate robots as small as 1 mm in the plane. The microcoils in the second layer are also able to generate sufficient magnetic field gradients in the workspace, while the traces below it are spaced adequately to eliminate their influence in the workspace. A new microrobot design also enabled the orientation control of the microrobot for performing micromanipulation tasks. However, only two robots could be independently actuated in this workspace due to interaction between the robots.In pursuit of actuation smaller and multiple robots in a small workspace, a serpentine coil based local magnetic field generating system was designed to control of the motion of magnets as small as 250 µm. The net size of the robot is 750 µm to enable orientation control and prevent tipping during motion. This system is capable of simultaneous independent closed loop control of up to 4 microrobots. The motion of the robot using the coils resembled that of a stepper motor which enabled the use of sine-cosine functions to specify currents in the coils for smooth motion of themicrorobot in the workspace. The experiments demonstrated the capability of the microrobot and platform to simultaneously actuate up to four robots independently and successfully perform manipulation tasks. The ability to control the orientation of the magnet is finally demonstrated that has improved ability to perform manipulation tasks.

This report explores a parallel implementation of the C++ MultiBoost open source library's AdaBoost.MH (Adaptive Boosting) algorithm (D. Benbouzid,2012), and the changes in performance as measured on the Texas Advanced Computing Center's Stampede supercomputer. This parallel implementation is based on the AdaBoost.PL Algorithm (Palit & Reddy,2012). The baseline is the AdaBoost.MH algorithm, and this algorithm's performance is contrasted against our AdaBoost.PL implementation. This report also explores the feasibility and effectiveness of other possibilities for optimization such as vectorization, cache optimizations, and GPU optimizations. The best performance increase we get is 2.7x speedup from a parallel implementation.
