Intelligent neuro-controller for navigation of mobile robot

This paper deals with the reactive control of an autonomous robot which move safely in a crowded real world unknown environment and to reach specified target by avoiding static as well as dynamic obstacle. The inputs to the proposed neurocontroller consist of left, right, and front obstacle distance to its locations and target angle between a robot and a specified target being acquired by an array of sensors. A four layer neural networks is used to design and develop the neurocontroller to solve the path and time optimization problem of mobile robots which deals the with cognitive tasks such as learning, adaptation, generalization and optimization. Back propagation method is used to trained the network. This paper analyzes the kinematical modeling of mobile robots as well as the design of control systems for the autonomous motion of the robot. The training of the nets and the control performances analysis have been done in a real experimental setup. The simulation results are compared with experimental results which are satisfactory and shows a very good agreement.
Improvised interfaces for real-time musical applications

Computers offer a wealth of promises for real-time musical control. One of them is to enable musicians to change the structure of their instruments in the same time they are playing them, allowing them to adapt their tools to their wills and needs. Few interaction styles provide enough freedom to achieve this. Improvised interfaces are tangible interfaces made out of found objects and tailored by their users. We propose to take advantage of these improvised interfaces to turn the surrounding physical environment into a dynamic musical instrument with tremendous possibilities. Methods dealing with design issues are presented and an implementation of this novel approach is described.
Making Things by Self-Assembly

Self-assembly—the spontaneous generation of order in systems of components—is ubiquitous in chemistry; in biology, it generates much of the functionality of the living cell. Self-assembly is relatively unused in microfabrication, although it offers opportunities to simplify processes, lower costs, develop new processes, use components too small to be manipulated robotically, integrate components made using incompatible technologies, and generate structures in three dimensions and on curved surfaces. The major limitations to the self-assembly of micrometer- to millimeter-sized components (mesoscale self-assembly) do not seem to be intrinsic, but rather operational: selfassembly can, in fact, be reliable and insensitive to small process variations, but fabricating the small, complex, functional components that future applications may require will necessitate the development of new methodologies. Proof-of-concept experiments in mesoscale self-assembly demonstrate that this technique poses fascinating scientific and technical challenges and offers the potential to provide access to hard-to-fabricate structures.
On the expressive power of CTL

We show that the expressive power of the branching time logic CTL coincides with that of the class of bisimulation invariant properties expressible in so-called monadic path logic: monadic second order logic in which set quantification is restricted to paths. In order to prove this result, we first prove a new composition theorem for trees. This approach is adapted from the approach of Hafer and Thomas in their proof that CTL coincides with the whole of monadic path logic over the class of full binary trees.
Burning of a Hadronic Star into a Quark or a Hybrid Star

We study the hydrodynamical transition from a hadronic star into a quark or a hybrid star. We discuss the possible mode of burning, using a fully relativistic formalism and realistic equations of state in which hyperons can be present. We take into account the possibility that quarks form a diquark condensate. We also discuss the formation of a mixed phase of hadrons and quarks, and we indicate which region of the star can rapidly convert in various possible scenarios. An estimate of the final temperature of the system is provided. We find that the conversion process always corresponds to a deflagration, never to a detonation. Hydrodynamical instabilities can develop on the front. We estimate the increase in the conversion's velocity due to the formation of wrinkles, and we find that although the increase is significant, it is not sufficient to transform the deflagration into a detonation in essentially all realistic scenarios. Convection does not always develop; in particular, the system does not develop convection if hyperons are not present in the initial phase and the newly formed quark phase is made of ungapped (or weakly gapped) quarks. On the contrary, the process of conversion from ungapped quark matter to gapped quarks always allows the formation of a convective layer. Finally, we discuss possible astrophysical implications of our results.
Multiple Scan Methodology for Detection and Tuning Small Delay paths

Digital life standard demands accuracy which requires Enhanced VLSI architecture in every aspect. Various chip defect identification methods focuses on stuck and sequential faults, this work focuses on categorizing the chip by testing with three different testing scenarios. Detecting and categorizing Small delay defects often requires sophisticated experimental setup which involves complex test procedures. Detecting a small delay defect and categorizing it on a run time chip is time and cost consuming. This work proposes an AC scan delay testing methodology to assure three stages of test coverage verification with reduced hardware requirements, (i) Finding the longest critical path in a chip (ii) Categorization of defective chips which overlaps the longest time bound predicted, based on its probability of failure attempts (iii) Extracting the waveform of each flip flop stages for post fabrication steps. A VHDL modelling of test bench generation will be designed using Modelsim simulation tool, the percentage of fault coverage achieved by our proposed AC plus scan method will be tested in s298 benchmark circuit under three frequency ranges (target, middle and contour). This chip defect identification methodology can be further extended to fault tolerant methodology.
Crowd Prefers the Middle Path: A New IAA Metric for Crowdsourcing Reveals Turker Biases in Query Segmentation

Query segmentation, like text chunking, is the first step towards query understanding. In this study, we explore the effectiveness of crowdsourcing for this task. Through carefully designed control experiments and Inter Annotator Agreement metrics for analysis of experimental data, we show that crowdsourcing may not be a suitable approach for query segmentation because the crowd seems to have a very strong bias towards dividing the query into roughly equal (often only two) parts. Similarly, in the case of hierarchical or nested segmentation, turkers have a strong preference towards balanced binary trees.
Antecedents and Consequences of Fairness Perceptions in Personnel Selection

Drawing on Gilliland’s selection fairness framework, we examined antecedents and behavioral effects of applicant procedural fairness perceptions before, during, and after a personnel selection procedure using a six-wave longitudinal research design. Results showed that both perceived post-test fairness and pre-feedback fairness perceptions are related to job offer acceptance and job performance after 18 months, but not to job performance after 36 months. Pre-test and post-test procedural fairness perceptions were mainly related to formal characteristics and interpersonal treatment, whereas pre-feedback fairness perceptions were related to formal characteristics and explanations. The impact of fairness attributes of formal characteristics and interpersonal treatment diminished over time, whereas attributes of explanation were only associated with pre-feedback fairness. Results are discussed in terms of theoretical implications for fairness research and for hiring organizations.
Thermal-Aware Placement for FPGAs Using Electrostatic Charge Model

A thermal-aware placement is proposed for FPGAs to reduce the peak temperature and maximum on-chip gradient temperature. A new thermal cost is defined for the simulation annealing core of the placer based on the electrostatic charge model instead of extracting temperature profile in each simulation iteration. The thermal cost change rather than its actual value is derived to keep the runtime complexity of the cost evaluation algorithm linear with the number of used logic blocks. Results show an average of 73% and 51 % reductions in the standard deviation and maximum gradient of temperature with less than 4% average wiring and delay penalty
Exploring the limits of RF shimming for high‐field MRI of the human head

Several methods have been proposed for overcoming the effects of radiofrequency (RF) magnetic field inhomogeneity in high‐field MRI. Some of these methods rely at least in part on the ability to independently control magnitude and phase of different drives in either one multielement RF coil or in different RF coils in a transmit array. The adjustment of these drive magnitudes and phases alone to create uniform RF magnetic (B1) fields has been called RF shimming, and has certain limits at every frequency as dictated by possible solutions to Maxwell's equations. Here we use numerical calculations to explore the limits of RF shimming in the human head. We found that a 16‐element array can effectively shim a single slice at frequencies up to 600 MHz and the whole brain at up to 300 MHz, while an 80‐element array can shim the whole brain at up to 600 MHz.

Distribution of Integrons and Phylogenetic Groups among Enteropathogenic Escherichia coli Isolates from Children <5 Years of Age in Delhi, India

Integrons by means of horizontal gene transfer carry multidrug resistance genes (MDR) among bacteria, including E. coli. The aim of this study was to determine the antibiotic resistance profiles and the genes associated with them, to gain insights in the distribution of phylogroups, prevalence, and characterization of class 1, 2 and 3 integrons among Enteropathogenic E. coli (EPEC) isolates, from children upto 5 years of age from Delhi and National Capital Region (NCR), India. A total of 120 E. coli isolates, including 80 from diarrheagenic E. coli (cases) and 40 from healthy isolates (controls) were recruited in this study. After isolation of E. coli, screening for EPEC was done by conventional multiplex PCR. Antibiotic suseptibility test was performed using disk diffusion method and further confirmed by minimum inhibitory concentration (MICs) by E-test. The presence and characterization of integrons and antimicrobial resistance genes were performed by PCR and DNA sequencing. Phylogeny determination was carried out by quadruplex PCR. EPEC strains were found in 64 of the 80 diarrheagenic cases, out of which 38 were MDR. In the 40 healthy controls, 23 were found to be EPEC strain, out of which only 2 were MDR. Amongst 80 diarrheagenic cases, class 1 integron were observed in 43 isolates, class 2 integron in 12 isolates and 9 isolates were found with co-existence of both. Similarly, in healthy controls; class 1 integron in 9 and class 2 integron in 7 isolates were observed with co-existence in 3 isolates. None of the isolates included class 3 integron. The dfr was the most commonly identified gene cassette within the integron-positive isolates. Phylogenetic studies showed considerable representation of phylogroup B2 in both diarrheagenic cases and healthy controls. This study reiterates the importance of class 1 integron predominantly for acquisition of antibiotic resistance genes among EPEC isolates. Furthermore, it also ascertains the possible association between multidrug resistance and presence of integrons. Approximately 91% of isolates were easily assigned to their respective phylogroups. Assessment of the relationship between antibiotic resistance and dominant phylogroups detected was also attempted. This study also highlights the increased burden of antimicrobial resistance in healthy controls.
Small-Sample Error Estimation for Bagged Classification Rules

Application of ensemble classification rules in genomics and proteomics has become increasingly common. However, the problem of error estimation for these classification rules, particularly for bagging under the small-sample settings prevalent in genomics and proteomics, is not well understood. Breiman proposed the "out-of-bag" method for estimating statistics of bagged classifiers, which was subsequently applied by other authors to estimate the classification error. In this paper, we give an explicit definition of the out-of-bag estimator that is intended to remove estimator bias, by formulating carefully how the error count is normalized. We also report the results of an extensive simulation study of bagging of common classification rules, including LDA, 3NN, and CART, applied on both synthetic and real patient data, corresponding to the use of common error estimators such as resubstitution, leave-one-out, cross-validation, basic bootstrap, bootstrap 632, bootstrap 632 plus, bolstering, semi-bolstering, in addition to the out-of-bag estimator. The results from the numerical experiments indicated that the performance of the out-of-bag estimator is very similar to that of leave-one-out; in particular, the out-of-bag estimator is slightly pessimistically biased. The performance of the other estimators is consistent with their performance with the corresponding single classifiers, as reported in other studies.
Real-time imaging of the somite segmentation clock: Revelation of unstable oscillators in the individual presomitic mesoderm cells

Notch signaling components such as the basic helix-loop-helix gene Hes1 are cyclically expressed by negative feedback in the presomitic mesoderm (PSM) and constitute the somite segmentation clock. Because Hes1 oscillation occurs in many cell types, this clock may regulate the timing in many biological systems. Although the Hes1 oscillator is stable in the PSM, it damps rapidly in other cells, suggesting that the oscillators in the former and the latter could be intrinsically different. Here, we have established the real-time bioluminescence imaging system of Hes1 expression and found that, although Hes1 oscillation is robust and stable in the PSM, it is unstable in the individual dissociated PSM cells, as in fibroblasts. Thus, the Hes1 oscillators in the individual PSM cells and fibroblasts are intrinsically similar, and these results, together with mathematical simulation, suggest that cell-cell communication is essential not only for synchronization but also for stabilization of cellular oscillators.

Structure of the Rad50·Mre11 DNA Repair Complex fromSaccharomyces cerevisiae by Electron Microscopy*

The RAD50 gene of Saccharomyces cerevisiae is one of several genes required for recombinational repair of double-strand DNA breaks during vegetative growth and for initiation of meiotic recombination. Rad50 forms a complex with two other proteins, Mre11 and Xrs2, and this complex is involved in double-strand break formation and processing. Rad50 has limited sequence homology to the structural maintenance of chromosomes (SMC) family of proteins and shares the same domain structure as SMCs: N- and C-terminal globular domains separated by two long coiled-coils. However, a notable difference is the much smaller non-coil hinge region between the two coiled-coils. We report here a structural analysis of full-length S. cerevisiae Rad50, alone and in a complex with yeast Mre11 by electron microscopy. Our results confirm that yeast Rad50 does have the same antiparallel coiled-coil structure as SMC proteins, but with no detectable globular hinge domain. However, the molecule is still able to bend sharply in the middle to bring the two catalytic domains together, indicating that the small hinge domain is flexible. We also demonstrate that Mre11 binds as a dimer between the catalytic domains of Rad50, bringing the nuclease activities of Mre11 in close proximity to the ATPase and DNA binding activities of Rad50.
Resisting Alignment: Negotiating Alignment, Responsibility, and Status in Everyday Life

Abstract The study of accounts, corrective practices, or aligning actions has grown to constitute a significant sub-discipline within everyday life sociology. Most work in this field starts with an assumption of order and assumes that accounts reestablish broken sociality. However, much accounting activity resists against alignment efforts, and alignment efforts can be used as a means of conflict. The present chapter aims to survey situations in which actors resist and negotiate alignment and the power and status conflicts involved in these negotiations. With these conflicts, participants also negotiate responsibility, which is here seen not as an internal attribute of actors, but a socially negotiated meaning as well. On a larger level, the present chapter shows how levels of meaning are intertwined in alignment situations, making them much more than mere tools to produce and protect order.
Free Space Detection: A Corner Stone of Automated Driving

Increasingly complex automated driving functions require ever more accurate environment models. If relevant information is missing, automated vehicle control may induce safety risks. In this paper, we describe a joint development of BMW and Continental used to ensure the safety of advanced driver assistance systems. We demonstrate free space detection (FSD) carried out on a stereo vision system and show how it contributes to a number of use cases in high-level driver assistance functionality. One major challenge is the diversity of requirements by various functions and we show how confidence estimation is key to serving them in parallel. Moreover, we demonstrate a novel semi-automatic validation procedure for the generation of ground truth data in order to assess FSD performance in real-world driving scenarios.
Use of Agricultural Waste for the Removal of Nickel Ions from Aqueous Solutions: Equilibrium and Kinetics Studies

� Abstract—The potential of economically cheaper cellulose containing natural materials like rice husk was assessed for nickel adsorption from aqueous solutions. The effects of pH, contact time, sorbent dose, initial metal ion concentration and temperature on the uptake of nickel were studied in batch process. The removal of nickel was dependent on the physico-chemical characteristics of the adsorbent, adsorbate concentration and other studied process parameters. The sorption data has been correlated with Langmuir, Freundlich and Dubinin-Radush kevich (D-R) adsorption models. It was found that Freundlich and Langmuir isotherms fitted well to the data. Maximum nickel removal was observed at pH 6.0. The efficiency of rice husk for nickel removal was 51.8% for dilute solutions at 20 g L -1 adsorbent dose. FTIR, SEM and EDAX were recorded before and after adsorption to explore the number and position of the functional groups available for nickel binding on to the studied adsorbent and changes in surface morphology and elemental constitution of the adsorbent. Pseudo-second order model explains the nickel kinetics more effectively. Reusability of the adsorbent was examined by desorption in which HCl eluted 78.93% nickel. The results revealed that nickel is considerably adsorbed on rice husk and it could be and economic method for the removal of nickel from aqueous solutions.
Challenges in Transition of Care for Patients With Anorectal Malformations: A Systematic Review and Recommendations for Comprehensive Care

BACKGROUND: Anorectal malformations are one of the most common congenital intestinal anomalies affecting newborns. Despite advances in neonatal care and surgical techniques, many patients with a history of anorectal malformations are affected by long-term challenges involving bowel and bladder dysfunction, sexual dysfunction, and psychosocial issues. These outcomes or challenges are additionally exacerbated by the lack of a structured transition of care from the pediatric to the adult setting. OBJECTIVE: The purpose of this review is to describe the long-term outcomes affecting patients with a history of anorectal malformations, review the current literature on transition of care, and make recommendations for developing a standardized program for transitioning care for a select group of colorectal surgical patients. DATA SOURCES: An extensive PubMed review of articles in English was performed to evaluate current best practices for chronic illnesses of childhood with residual symptoms or need for medical care into adulthood. STUDY SELECTION: Meta-Analysis of Observational Studies in Epidemiology group guidelines were followed. MAIN OUTCOME MEASURES: The primary outcome for this review was the existence of transitional services for patients with a history of anorectal malformations and evaluations of long-term outcomes affecting patients with a history of anorectal malformations. RESULTS: Systematic review revealed improved results in transition programs as determined by patient follow-up, medication adherence, and patient and family satisfaction through the use of multidisciplinary teams. Standardized tools for assessing all aspects of patient outcomes and quality of life are essential for describing the burden of disease affecting a transitioning population. LIMITATIONS: This is a retrospective review of the current status of a complex and rapidly evolving field of delivery of care. More work is needed to apply uniform approaches and assess the impact, patient outcomes, and quality of life. CONCLUSIONS: Patients who undergo childhood procedures for anorectal malformations often experience chronic symptoms related to the bowel, bladder, and reproductive organs, as well as psychosocial disturbances. This population will benefit from appropriate engagement in transitional care plans. See Video Abstract at http://links.lww. com/DCR/A543.
