Angle Estimation for Adaptive Linear Array using PCA-GS-ML Estimator

The maximum likelihood (ML) angle estimator can yield optimal angle estimation performance. In the work presented here, a fast algorithm for solving the global optimal solution of the ML angle estimator based on principal component analysis (PCA) and grid search (GS) is developed. Utilizing the low-rank property of the mainbeam steering matrix, the log-likelihood function can be decomposed as a combination of the relevant quantities of basis vectors of the low-rank subspace. Thus, evaluation of the log-likelihood function can be realized in a lower dimensional space. Although GS is also required, the computational complexity can be greatly reduced, and the global optimal solution can be obtained.
On the Well-Posedness , Stability And Accuracy Of An Asymptotic Model For Thin Periodic Interfaces In Electromagnetic Scattering Problems

We analyze the well-posedness and stability properties of a parameter dependent problem that models the reflection and transmission of electromagnetic waves at a thin and rapidly oscillating interface. The latter is modeled using approximate interface conditions that can be derived using asymptotic expansion of the exact solution with respect to the small parameter (proportional to the periodicity length of oscillations and the width of the interface). The obtained uniform stability results are then used to analyze the accuracy (with respect to the small parameter) of the proposed model.
Interchangeability and specificity of components from the quorum-sensing regulatory systems of Vibrio fischeri and Pseudomonas aeruginosa

Autoinduction is a conserved mechanism of cell density-dependent gene regulation that occurs in a variety of gram-negative bacteria. Autoinducible luminescence in Vibrio fischeri requires a transcriptional activator, LuxR, while a LuxR homolog, LasR, activates elastase expression in Pseudomonas aeruginosa. Both LuxR and LasR require specific signal molecules, called autoinducers, for activity. We show here the activation in Escherichia coli of the V. fischeri luminescence (lux) operon by LasR and of the P. aeruginosa elastase gene (lasB) by LuxR when each is in the presence of its cognate autoinducer. Neither LuxR nor LasR showed appreciable activity with the heterologous V. fischeri or P. aeruginosa autoinducer. This supports the view that there is a direct interaction of each transcriptional activator with its proper autoinducer and suggests that there are conserved, autoinduction-related elements within the promoter regions of these genes.
Robust OFDMA Frame Synchronization Algorithm on Inter-Cell Interference

Cellular OFDMA system is susceptive to inter-cell interference when a frequency reuse factor is one and all neighboring cells are fully loaded. At the cell edge, particularly, a severe synchronization error may occur due to decreased signal-to-interference ratio. In this paper, therefore, we propose a robust frame synchronization method in inter-cell interference for OFDMA systems. The proposed algorithm shows a clear peak at the correct frame timing and has low computational complexity

Inside-Out Technique Cholesteatoma Surgery: A Retrospective Long-Term Analysis of 604 Operated Ears Between 1992 and 2006

Objective: To retrospectively present the experience with 586 patients or 604 ears operated for cholesteatoma. Patients: All patients, adults and children, with histologically confirmed cholesteatoma and a mean age of 36 years (3 to 86 yr). Intervention: With the inside-out technique, cholesteatoma is eradicated from the epitympanum toward the mastoid: small cholesteatoma is removed by a transcanal approach, and medium-sized cholesteatoma is removed by a retroauricular atticotomy and cartilaginous reconstruction of the canal wall. An extended cholesteatoma is eradicated by a classical canal wall down radical cavity. A simultaneous reconstruction of the middle ear by tympano-ossiculoplasty is performed. Main Outcome Measures: Postoperative anatomic results with regard to recurrence, intactness of the tympanic membrane, and condition of the ear site. Auditory performance including air-bone gap, auditory threshold and improvement of hearing. Results: A complete removal of cholesteatoma in 93% of adults and 87% of children (mean postoperative follow-up, 10 yr; range, 2-15 yr) was achieved, with 95% dry ears and a mean air-bone gap of less than 30 dB in 78% postoperatively. Nine percent of all patients were lost to follow-up. Conclusion: The inside-out technique allows the safe removal of cholesteatoma according to the extent of disease combining the advantages of the canal wall down technique with respect to radicality of cholesteatoma removal and of the canal wall up technique with respect to functional results, with the added advantage of single-stage reconstruction.
Comparative analysis of basaloid and typical squamous cell carcinoma of the oesophagus: a molecular biological and immunohistochemical study

Twenty‐three cases of basaloid squamous cell carcinoma (BSCC) and 23 stage‐matched pairs of typical squamous cell carcinoma (SCC) of the oesophagus were investigated for molecular aberrations. Polymerase chain reaction (PCR) was used to detect loss of heterozygosity at the APC, RB, and MCC gene loci, while differential PCR was carried out to detect amplification of the CDK4 gene. In addition, the level of expression of the p53 and RB proteins in the tumour tissue was assessed by immunohistochemistry. Loss of heterozygosity (LOH) at the APC and MCC loci was about twice as common in BSCC as in SCC (40% vs. 21% and 33% vs. 12%, respectively), with co‐existence of LOH at both loci occurring only in BSCC. LOH frequency at the RB gene locus was not remarkably different in either BSCC or SCC (20% vs. 24%, respectively). On immunohistochemistry, accumulation of p53 protein was slightly more frequent in BSCC than in SCC (61% vs. 52%), whereas the rate of loss of RB protein expression was about equal in both types of carcinoma (9% vs. 13% BSCC and SCC, respectively). There was no detectable amplification of the CDK4 gene in either type of tumour. Although the observed differences did not achieve statistical significance, this work has further highlighted possible differences between the molecular pathogenesis of BSCC and SCC.

The Local Government's Supply Chain Strategy to Empower the Traditional Fishermen in Southern Coast of Java Island

This study aims to investigate how to determine the supply chain system strategy of the price efficiency for traditional fishermen in the southern coast of Java Island, and to find out how to determine the market selling price of the fish to improve the competitiveness of traditional fishermen. This study employed qualitative method with a critical paradigm based on Karl Marx thought to answer the problem of economic competitiveness of traditional fishermen. This study’s respondents are traditional fishermen and Head of Fishery Department in Pangandaran, Pandeglang, Cilacap and Gunung Kidul. The results show that the role of fish auction places that has been organized by the Fishery Department of district government can reduce the supply chain-gap from fishermen to fish processing companies and household consumers. Moreover, the supervisor of fishery department acknowledged that the managers of fish auction place located in every district on the south coast of Java Island is still hampered by bakulan/the middlemen. Bakulan in each fish auction place determines the market price of fishes and provides working capital to the fishermen when they start working to find fishes in the sea. Furthermore, the results also show that the fishermen fish auction’s location – fish processing industries/consumer is the To enhance the fisherman’s economic competitiveness, the Department of Fishery must oversee the operating activity of fish auction and establish a fair price index of every type of fish caught by fishermen in every district.

Forecasting tourism demand with composite search index :

Researchers have adopted online data such as search query volumes to forecast tourism demand for a destination, including tourist volumes and hotel occupancy. However, the massive yet highly correlated query data pose challenges when researchers attempt to include them in the forecasting model. We propose a framework and procedure for creating a composite search index adopted in a generalized dynamic factor model (GDFM) to forecast tourist demand in a destination. This research empirically tests the framework in predicting monthly Beijing tourist volumes. Findings suggest that the proposed method improves the forecast accuracy of monthly Beijing tourist volumes compared with two benchmark models: a time series model and a model with an index created by principal component analysis. The method demonstrates the combination of composite search index and a GDFM in accurately forecasting tourism demand.
Structure conditions function and vice versa.

The Alicante meeting was devoted to the proposition that “The structure of the heart determines its function and vice versa”. This was not to indicate that we did not appreciate the astonishing progress in cardiology achieved by developments such as molecular biology, nor to re-run old controversies. It was rather to remind ourselves that new observations at the molecular level must ultimately be correlated with ventricular structure and mechanics; and furthermore that to concentrate research totally on the molecular level to the exclusion of morphology, pathomorphology and the cardiodynamics of normal and diseased hearts, with the mistaken idea that all is known about these aspects, would be shortsighted. In cardiology morphology is held in low esteem. One main reason is the lack of preparation techniques to gain access to the intricate weave of the heart muscle. Tissue analysis has remained on a strictly cellular level. A common morphological substrate of myocardial failure has not been identified [70]. There is growing evidence in recent investigations [10,25,82,83] that morphology will not succeed in yielding a comprehensive understanding of the wide palette of adaptive heart diseases until tissue analysis engages also in the analysis of the heart’s mesh texture. In fact, until recently there were no appropriate methods available to analyze spatial myocardial and connective tissue weave, neither post mortem, nor in vivo. However, recent advances in imaging techniques indicate that in the near future pathomorphology will be obliged to extend its analytical spectrum to keep abreast with clinical diagnostics.
Developing an adaptive e-learning system for learning excel

Adaptive learning for individual learners has recently become popular in education. This study aims to fill the void in the existing literature by building an adaptive learning system with evaluation rubrics based on the dynamic scaffolding theory in order to promote the learning achievement. An experimental design was conducted to evaluate the effectiveness of using dynamic scaffoldings and self-assessment rubrics in the learning process. Sixty university students participated in this study and executed a pre-test and a post-test. The independent-sample t-test procedure was applied in this study to examine differences of learning achievement between experimental group and control group. Research results revealed that there is a significant difference in learning achievement between these two groups. Finally, some suggestions are provided for research scholars and future research direction according to research findings.
Efficient uplink time difference of arrival mobile device localization in cellular networks

In this work, mobile station (MS) localization in cellular systems is considered based on uplink time difference of arrival (UTDOA) of MS signal at spatially separated base stations with known locations is presented. The UTDOA estimation is conducted using normalized least mean square (NLMS) based adaptive line enhancer (ALE) followed by a cross correlation. More precisely, the use of ALE-pre-filtered cross correlation is proposed in hyperbolic localization to improve the accuracy of UTDOA estimation for reducing the uncertainty in localizing the mobile station. Computer simulation results indicate that proposed ALE-UTDOA technique can achieve superior positioning accuracy than conventional cross correlation (CC) based method with range of 67%-75%.
Quality Improvement and Time to Lift the Ban on Mobile Phones in Secondary Schools

This study was conducted over three months from March to May 2018, at a time when modern mobile phones possess various functions that are invaluable for learning, teaching and communication purposes. Whilst some countries with a quest to improve quality of education, have embraced the continuously evolving technological capacities of mobile phones for educational purposes, secondary school pupils in Zimbabwe are prohibited from using mobile phones in class as these are viewed to be disruptive rather than useful. This study investigated stakeholders’ perceptions of potential utilisation of cell phones by secondary school students as learning tools that enhance quality of education. The sample included 15 secondary schools in Mazowe District. From these, the District Education Officials, headmasters, teachers, pupils and parents were given questionnaires to complete. Validation interviews were conducted for triangulation purposes. The findings revealed strong positive responses in favour of allowing the utilisation of mobile phones as learning tools in Zimbabwean secondary schools although some challenges in the implementation process were cited. These included possibilities of: student distraction in class; cheating; inappropriate video recording of class events and the publication of captured material on social platforms which could be harmful to other learners and the school. The issue of cost of data also came up. The study recommended the removal of the blanket ban on the use of mobile phones; instead, school authorities were encouraged to focus on developing strategies for addressing the implementation challenges cited. It is also critical to make sure that accessible cheap data be made available to learners in secondary schools. Schools in Zimbabwe should form networks so that cheap data is made available by sharing the networks. Schools in Zimbabwe, like institutions of higher learning, are encouraged to embrace the National Research and Education Network (NREN) concept which specialises in internet service provision dedicated to supporting the needs of education in Zimbabwe.

Specificity of the bacteriophage Mu mom+ -controlled DNA modification

Bacteriophage Mu DNA was labeled after induction in the presence of [8-3H]adenine. Purified DNA was enzymatically digested, and the 3H-labeled dinucleotides were isolated. Approximately 15 to 20% of the adenine residues were modified to a new form, Ax, as observed previously (S. Hattman, J. Virol. 32:468-475, 1979) in bulk DNA. Paper electrophoretic analysis revealed that only two dinucleotide species contain Ax, namely, (Ax,C) and (Ax,G). The observation that only C and G are the nearest neighbors of Ax is consistent with the proposal of Kahmann and Kamp (R. Kahmann and D. Kamp, J. Mol. Biol., in press) that modification of Mu DNA occurs at the A residue within the pentanucleotide sequence, 5'. (CG)-A-(GC)-N-Py.3'.
Acquiring design knowledge from design cases

Single-purpose learning algorithms are often not efficient in acquiring knowledge for expert systems in design. The authors present a method that learns design knowledge from design cases by the extensive generalization of abstract design schemas, which function as both a representation schema storing generalized knowledge and a memory organization facility indexing specific cases and aiding in retrieval. Unlike most current machine learning algorithms, it aims at multiple targets of prediction, feature reminding, case retrieval and new case generation in a single system. <<ETX>>
Successful Treatment of Obstructive Sleep Apnea Syndrome Improves Autonomic Nervous System Dysfunction

Autonomic nervous system (ANS) dysfunction may be implicated in the subsequent development of cardiovascular disease in patients with obstructive sleep apnea syndrome (OSAS). To confirm the relation between OSAS and ANS dysfunction, we prospectively investigated ANS function in 7 patients with moderate or severe OSAS; 7 healthy age-matched volunteers were for control. We also studied ANS function before and after treatment in the patients with OSAS to evaluate the effect of OSAS treatment on ANS dysfunction. The body mass index of patients with OSAS was 32.2 (27.4–45) (median [range]) kg/m2. The patients were treated by nasal continuous positive airway pressure (n = 5) or uvulopalatopharyngoplasty (n = 2). The apnea/hypopnea index decreased markedly from 42.1 (30.6–77.2) events/hr of sleep before treatment to 2.3 (1.4–3.8) after treatment. To evaluate ANS function, the coefficient of variation of the RR interval (CV-RR) and corrected QT (QTc) interval on the electrocardiogram at rest and the heart rate (HR) responses to blood pressure (BP) changes during the Valsalva maneuver were studied. Baseline HR of OSAS patients was significantly higher than that of the control subjects (p < .05). The Valsalva ratio (VR), baroreflex sensitivity (BRS), and CV-RR values in patients with OSAS were significantly lower than those of the control subjects (all, p < .005). However, there were no significant differences in systolic and diastolic BP or QTc intervals. After treatment, VR, BRS, and CV-RR values increased significantly compared with those before treatment in patients with OSAS (all, p < .05). There were no significant differences in systolic and diastolic BP, HR, or QTc intervals measured before and after treatment. These results suggest that impaired ANS function is present in patients with OSAS and can be improved by successful treatment of OSAS.
Efficient tools for quantum metrology with uncorrelated noise

Quantum metrology offers enhanced performance in experiments on topics such as gravitational wave-detection, magnetometry or atomic clock frequency calibration. The enhancement, however, requires a delicate tuning of relevant quantum features, such as entanglement or squeezing. For any practical application, the inevitable impact of decoherence needs to be taken into account in order to correctly quantify the ultimate attainable gain in precision. We compare the applicability and the effectiveness of various methods of calculating the ultimate precision bounds resulting from the presence of decoherence. This allows us to place a number of seemingly unrelated concepts into a common framework and arrive at an explicit hierarchy of quantum metrological methods in terms of the tightness of the bounds they provide. In particular, we show a way to extend the techniques originally proposed in Demkowicz-Dobrzański et al (2012 Nature Commun. 3 1063), so that they can be efficiently applied not only in the asymptotic but also in the finite number of particles regime. As a result, we obtain a simple and direct method, yielding bounds that interpolate between the quantum enhanced scaling characteristic for a small number of particles and the asymptotic regime, where quantum enhancement amounts to a constant factor improvement. Methods are applied to numerous models, including noisy phase and frequency estimation, as well as the estimation of the decoherence strength itself.
Families of Algebraic Varieties Parametrized by Topological Spaces

We study families of algebraic varieties parametrized by topological spaces and generalize some classical results such as Hilbert Nullstellensatz and primary decomposition of commutative rings. We show that there is an equivalence between the category of bivariant coherent sheaves and the category of sheaves of finitely generated modules.
The anaphase-promoting complex/cyclosome: APC/C

The major ubiquitin ligase required for mitosis is the anaphase-promoting complex/cyclosome (APC/C). This unusually complex E3 ubiquitin ligase targets cell-cycle-related proteins such as cyclins and securin for degradation by the proteasome in mitosis and meiosis. The APC/C is regulated by
HOW ATTITUDINAL AND BEHAVIOURAL LOYALTY IS FORMED? A CASE OF GARUDA INDONESIA’S CUSTOMER SATISFACTION

The purpose of this research is to examine service quality and perceived price fairness in airline industry and how these variables influences customer satisfaction and attitudinal and behavioural loyalty. The research is based on the sample of 304 Garuda Indonesia’s customers who have completed 37 questions questionnaire. This research uses Structural Equation Modelling (SEM) to analyse the responses. The research concludes that tangibility, assurance, and empathy are factors in service quality that significantly influence customer satisfaction. Furthermore, customer satisfaction and perceived price fairness also influence attitudinal and behavioural loyalty. This research is limited on the evaluation of Garuda Indonesia airlines among Indonesian passengers. Thus, this research cannot be generalised to the other airline passengers, in Indonesia or other countries. This research provides the first insight of Indonesian national airline, Garuda Indonesia, especially in the terms and relationship of perceived price fairness, customer satisfaction, and attitudinal and behavioural loyalty.
