A comprehensive analysis of the polygalacturonase family of wheat (Triticum aestivum L.) shed light on important genes affecting pollen development and anther dehiscence

Background: Polygalacturonase (PG) belongs to a large family of hydrolases that undertake many important functions in cell separation during plant growth and development by degrading pectin. The specific expression of PG genes in pollen may have great significance for plant male sterile research and hybrid wheat breeding. However, it has not been reported in wheat ( Triticum aestivum L.). Results: Therefore, we systematically studied the PG gene family using the latest published wheat reference genomic information. A total of 113 PGs were identified and renamed as TaPG01 - 113 based on their position on the chromosome. They were unequally distributed on 21 chromosomes and were classified into six categories of A-F. Analysis of gene structures and conserved motifs revealed that the TaPGs of Class C and D had relatively short gene sequences and a small number of introns, and Class E TaPGs were the least conserved and all members did not have III conserved domain. Segmental duplication has been shown to be one of the major drivers of the expansion of the wheat PG gene family. The cis-element predictions indicate that wheat PGs had a wide range of functions, including response to light, hypothermia, anaerobic and hormonal stimulation, and also involved in meristematic tissue expression. In addition, twelve spike-specific expressions of TaPGs were screened using RNA-seq data, and finally three important genes were identified by expression analysis in the sterile and fertile anthers of thermo-sensitive male sterile wheat. TaPG93 was involved in the pollen development and elongation of pollen tubes, and TaPG87 and TaPG95 played important roles in the separation of pollen grains and the cracking of anthers dehiscence. Conclusions: This study, we performed a thorough analysis of the wheat PG gene family and finally obtained three TaPGs that affect wheat fertility. This will lay a solid foundation for the function exploration of wheat PG gene family and provide new enlightenment for the fertility conversion mechanism of male sterile wheat.
Clonality of Enterococcus Faecalis Isolates in Stool and Urine Samples of Patients with Community-Acquired Urinary Tract Infection, and its Link with Virulence Gene Determinants and Antimicrobial Resistance Phenotypes

Background Community-acquired urinary tract infection (CA-UTI) could be caused through endogenous or exogenous routes. To show this relationship, we investigated molecular fingerprints and genotypes of paired Enterococcus faecalis isolates from the urine of symptomatic patients and their fecal samples. Results Out of the studied patients, 63 pairs of E. faecalis isolates were obtained simultaneously from their urine and feces samples. All the strains were sensitive to vancomycin, linezolid, nitrofurantoin, and daptomycin (MIC value: ≤4 µg/ml), whileresistance to tetracycline (Urine: 88.9%; stool: 76,2%) and minocycline (Urine: 87.3%, stool: 71.4%) wasdetected in most of them. The most common detected virulence genes were included efbA, ace, and gelE. RAPD-PCR and PFGE analyses showed same patterns of molecular fingerprints between paired of the isolates in 26.9% and 15.8% of the patients, respectively. Conclusions Similarity of E. faecalis strains between the urine and feces samples confirmed the occurrence of endogenous infection via contamination with colonized bacteria in the intestinal tract. Carriage of a complete virulence genotype in the responsible strains was statistically in correlation with endogenous UTI, which show their possible involvement in pathogenicity of uropathogenic E. faecalis strains.
Expressing Emotions in Social Robotics - A Schematic Overview Concerning the Mechatronics Aspects and Design Concepts

Abstract Facial features play an important role in expressing emotional state. Therefore, rendering realistic facial expressions plays an important role in the development of social robots within HRI. Hence, the design solutions must meet these requirements. Often mechatronic and design solutions poorly chosen can lead to unsatisfactory results. In this paper, a schematic overview concerning the design solutions adopted in the development of social robots is presented.

Through-silicon IR image to CAD database alignment

We perform automated alignment of a device's CAD layout to its through silicon-IR image. Light refraction of the optical system blurs and distorts the shape and size of features, causing both edge-based and intensity-based cross-correlation techniques to fail. Our alignment methodology consists of pre-processing (equalization) of the images, followed by sub-resolution offset computation We apply a modeled point spread function (PSF) of the optical system to the CAD image to increase its resemblance to the optical image (resolution-equalization). Using our alignment algorithm, which combines image equalization, over-sampling, and cross-correlation, we demonstrate through-Silicon placement accuracy of 0.1 /spl mu/ with a 1 /spl mu/ resolution optical system.
Modeling and Diagnosing Eccentricity Fault Using Three-dimensional Magnetic Equivalent Circuit Model of Three-phase Squirrel-cage Induction Motor

Abstract This article presents the three-dimensional modeling of an induction motor using a magnetic equivalent circuit. The main goal of introducing the three-dimensional model is to include axial fluxes in the machine equations. Furthermore, enhancement of the precision of teeth flux estimation and air-gap permeances, as the most important and dominant factors, is another achievement of this model compared to that of the two-dimensional model. This increases the accuracy of the estimated torque. Although it is possible to include the impact of the bar skew in the two-dimensional modeling using a magnetic equivalent circuit, this can be included more precisely in the three-dimensional model due to the three-dimensional nature of the bar skew. Therefore, the three-dimensional model as an efficient method with rapid computations and suitable precision is used for modeling various types of eccentricity. It is shown that the three-dimensional model results are closer to the experimental results compared to that of the two-dimensional model. This confirms the merit of the three-dimensional model. Also, this method can be a proper substitution to the finite-element method in modeling a machine under fault and fault diagnosis.
An evaluation of the military extension internship program

Griffin, Lynette M. M.S., Purdue University, May 2015. An Evaluation of the Military Extension Internship Program. Major Professor: Dr. Natalie Carroll. The Department of Defense (DoD) identified a need in military communities, both on and off installations, to offer high quality child care and youth services to military families as well as civilian families who serve the military communities. In response, the Office of the Secretary of Defense – Military Community and Family Policy (OSD-MC and FP), United States Department of Agriculture (USDA)’s National Institute of Food and Agriculture (NIFA) and Purdue University created the Purdue University Military Extension Internship Program (MEIP) to help university students and recent graduates gain professional skills through unique internships that provide real-world work experience with military child and youth programs. The MEIP was established five years ago and, to date, has not completed a formal evaluation that utilizes in-depth interviews to examine and understand the participants’ views of their internship experience. Therefore, the MEIP Evaluation reported here serves as the program’s first formal evaluation and provides an understanding of the career choice outcomes of interns and their personal self-efficacy perceptions to stakeholders: the principal investigator, program coordinator, and program partners.
Are They All Created Equal? A Comparison of Different Concept Inventory Development Methodologies

The creation of the Force Concept Inventory (FCI) was a seminal moment for Physics Education Research. Based on the development of the FCI, many more concept inventories have been developed. The problem with the development of all of these concept inventories is there does not seem to be a concise methodology for developing these inventories, nor is there a concise definition of what these inventories measure. By comparing the development methodologies of many common Physics and Astronomy Concept Inventories we can draw inferences about different types of concept inventories, as well as different valid conclusions that can be drawn from the administration of these inventories. Inventories compared include: Astronomy Diagnostic Test (ADT), Brief Electricity and Magnetism Assessment (BEMA), Conceptual Survey in Electricity and Magnetism (CSEM), Diagnostic Exam Electricity and Magnetism (DEEM), Determining and Interpreting Resistive Electric Circuits Concept Test (DIRECT), Energy and Motion Conceptual Survey.
Propagation models at 5.8 GHz-path loss and building penetration

This paper presents a propagation study at 5.725 GHz-5.825 GHz, within the U.S. Unlicensed National Information Infrastructure (U-NII) band. Propagation path loss is measured at 5.8 GHz in a residential area near Boulder, Colorado. Experimental sets of data are collected for a 100 MHz broadband channel, used to establish a high-speed (T1) data link. A plurality of propagation models are referenced, reviewed and commented upon. Data sets are separated into line of sight (LOS) and non-line of sight (NLOS) subsets, and in each case a suitable model is found to match our measured data. We show in particular that, under certain conditions, and with a LOS/NLOS distinction, the use of widely known models may be extended to a broadband channel at 5.8 GHz. These results are noteworthy since these propagation models were designed for cellular and PCS use at lower frequency and narrow-band channels. Subsequently we study indoor propagation: penetration losses into residences are measured, average and standard deviation values are derived for in-building penetration. These values are analyzed in conjunction with the previous modeling, and lead to guidelines for indoor coverage.
Multi-Body Contact Dynamics Analysis of Angular Contact Ball Bearing

The 3-D multi-body contact dynamics simulation model was built by ADAMS base on the Hertz contact theory and multi-body contact dynamics, which considered the dynamics relationship among the ball, ring and cage of the bearing. Considering the clearancesfrictions and loads, results that contained deformation and displacement of the bearing, trajectory of the CM of the cage and the dynamic contact force were obtained by means of the 3-D multi-body contact dynamics model simulation and statics calculation. The outcomes got from two different methods are consistent, so the 3-D multi-body contact dynamics simulation model has the positive significance on dynamic design and engineering application of the bearing.
A lane detection algorithm for personal vehicles

By the term “personal vehicle,” we mean a simple and lightweight vehicle expected to emerge as a personal ground transportation device. The motorcycle, electric wheelchair, and motor‐powered bicycle are examples of the personal vehicle and have been developed for personal transportation use. Recently, a new type of intelligent personal vehicle called the Segway has been developed, which is controlled and stabilized by using on‐board intelligent multiple sensors. The demand for such personal vehicles is increasing: (1) to enhance human mobility, (2) to support mobility for elderly persons, and (3) to reduce environmental load. With the rapid growth of the personal vehicle market, the number of accidents caused by human error is also increasing. These accidents are associated with driving capabilities; to enhance or support driving capabilities as well as to prevent accidents, intelligent assistance is necessary. One of the most important elementary functions for personal vehicles is robust lane detection. In this paper, we develop a robust lane detection method for personal vehicles in outdoor environments. The proposed lane detection method employs a 360° omnidirectional camera and unique robust image processing algorithm. In order to detect lanes, a combination of the template matching technique and the Hough transform is employed. The validity of the proposed lane detection algorithm was confirmed with a prototype vehicle under various types of sunshine conditions. © 2011 Wiley Periodicals, Inc.

Interferon Gamma Release Assay After BCG Vaccination Among Newborns and Family Members Living in an Overcrowded Area in Jakarta, Indonesia

IntroductionActive tuberculosis (TB) patient is a potential source of Mycobacterium tuberculosis transmission in an overcrowded and poor area. Family members living in the same house may have been infected or latent tuberculosis infection (LTBI) may develop. The aim of the study was to explore LTBI among newborns and their family members living in an overcrowded area in Jakarta, Indonesia. MethodsA prospective analytical study was conducted among newborns from October 2016 to March 2017. Interferon gamma release assay (IGRA) was examined before BCG vaccination and after 12 weeks. In parallel, TB active case finding was performed among family members of the newborns.ResultsOf 135 newborns, only 117 (86.7%) came for BCG vaccination. Of 346 family members screened, 8 (2.3%) were detected as untreated active pulmonary TB, confirmed by positive sputum and/or MTB culture. Family members living in the same house with active TB individuals (p=0.011, OR 2.69) as well as being males (p = 0.025; OR 1.68) had a significant higher risk of having a positive IGRA. ConclusionsUntreated pulmonary TB infection in overcrowded areas infects the surrounding neighbors, resulting in latent TB infection. An active program for detecting pulmonary TB cases and preventive measures need to be taken seriously to contain the potential spreading of the infection.

An Evaluation of Different Controllers Based on the Network Frequency Maintenance Strategy for a Large and Multi-control-area Interconnected Power System

Abstract—Maintaining the network frequency at its nominal value due to the load changes is one of the most important issues in the control and operation schedule of a large and multi-area interconnected power system. For the effective control solution, two types of tie-line bias control strategy-based controllers have been applied, i.e., classical and improved controllers. The classical controllers using conventional regulators, including integral, proportional–integral and proportional-integral-derivative, have achieved initial control results to bring the steady state back to the network. However, due to the very poor control features (e.g., large overshoots and long settling times), they need to be replaced with improved controllers, such as fuzzy logic and artificial neural network. To obtain an entire evaluation of the application of different load-frequency controllers, a five-control-area interconnected power system was built as a typical case study. Three improved controllers using proportional-plus-integral-based fuzzy logic and artificial neural network-based non-linear autoregressive moving average (NARMA-L2) architectures as well as their hybrid combination will also be investigated in this study. Simulation results obtained reveal that the improved controllers have obtained smaller overshoots (from 13.95 to 84.18%) and shorter settling times (from 19.91 to 65.71%) compared with the classical controllers.
The Role of Information Technologies to Address Data Handling in Construction Project Management

AbstractConstruction is an extremely information-dependent industry in which a project’s success largely depends on good access to and management of data. Effective project management requires the characterization of its challenging issues and the use of appropriate tools for data handling. For this purpose, the construction industry is increasingly adopting the use of information and communication technologies (ICT) in recent years. Given the acknowledged potential of ICT to bring about improvements in other industries, many initiatives have been undertaken to develop appropriate tools to support various tasks during the construction project lifecycle. This paper focuses on the proposals that use ICT to provide access to the data and take advantage of this access to manage crucial issues within project management such as costs, planning, risks, safety, progress monitoring, and quality control. The authors will demonstrate that suitable data handling facilitates and improves the decision-making process an.
Adaptive sidelobe cancellation of wide-band multipath interference

The steady-state performance of a narrow-band sidelobe canceller using a single auxiliary element with tapped delay line is analyzed for a simple two-path interference model, and an impulse response model is developed to provide insight as to the cancellation performance that might be expected. Computer solutions are then presented for various combinations of signal and multipath parameters. It is shown that auxiliary delay taps are required for effective cancellation of wide-band multipath interference, even for fractional bandwidth-delay products. Good cancellation is generally achieved provided that 1) the delay line taps are spaced much closer than the Nyquist sampling rate, and 2) the total length of the delay line considerably exceeds the longest multipath delay, depending on multipath component strengths.
Development and evaluation of a 3D ultrasound imaging system

The use of a 3D ultrasound imaging to perform a prostate examination will overcome the limitations of conventional 2D transrectal ultrasound (TRUS) and permit the estimation of prostate and tumor volumes with greater accuracy and and consistency. In this way, the diagnosis and staging of prostate cancer can be made more accurate and less operator dependent. With a 3D ultrasound imaging system, the patient's prostate can be scanned in only a few seconds and the resulting 3D image can be later manipulated and viewed interactively on a computer, after the patient has departed, and prostate and tumor volumes can be measured with better accuracy and reproducibility. The authors developed a 3D TRUS system to image the prostate.
Optimization Problems of Costs in a MultiState System with Imperfect Maintenance

We consider optimal replacement policies with periodic imperfect maintenance actions and minimal repairs. The multistate system is minimally repaired at failure and imperfect maintenance actions are regularly carried out for preventive maintenance. The discrete modified Weibull distribution is introduced and some cost functions applied to this distribution are defined in order to be minimized. Moreover, we assume that the costs of preventive maintenance depend on the degree of repair via a Kijima type 2 model. For illustrative purpose, the obtained results are applied on sets of simulated data.
Ionospheric and auroral clutter models for HF surface wave and over‐the‐horizon radar systems

The detection performance of high frequency surface wave radar (HFSWR) and high frequency over‐the‐horizon radar (OTHR) systems is heavily influenced by the presence of radar clutter. In HFSWR systems, the clutter has its origins in vertical‐incidence ionospheric reflections, whereas in OTHR systems, the origin is Bragg backscatter from plasma structures in the auroral zone. This paper models the spreading of the radar clutter signal in the Doppler and angle‐of‐arrival domains that arises from forward‐scattering effects as the radar pulse propagates through regions of ionospheric plasma irregularities. The models use a geometric optics approach to determine the power spectrum of the radar signal phase. This power spectrum is then used to simulate three‐dimensional space‐time‐range radar data cubes. The accuracy of the models is tested by comparing the simulated data to measured data cubes. As an application, the data are then used to evaluate the performance of the newly developed fast fully adaptive (FFA) space‐time adaptive processing (STAP) scheme to improve the extraction of target echoes from a clutter background.
