Systematic analysis of JmjC gene family of Brassica napus and KDM5 subfamily involved in abiotic stress response

Background: Jumonji C (JmjC) proteins play an important role in plant development and stress response through the removal of lysine methylation from histones. Brassica napus, which originated from spontaneous hybridization between Brassica rapa and Brassica oleracea, is the most important oilseed crop after soybean, but evolutionary relationships and functions of JmjC proteins remain unclear. Results: 65 JmjC genes were identified from B. napus genome, 29 from B. rapa, and 23 from B. oleracea. These genes were grouped into seven clades according to conserved sequences, and their catalytic activities of demethylation were predicted. Group-KDM4/JHDM3 for H3K4/9/27/36, Group-KDM5A/B for H3K4, Group-JmjC domain-only A/B for H3K27/36, Group-KDM3/JHDM2 for H3K9, and Group-JMJD6 may be for arginine demethylases. B. napus inherited most of its JmjC genes from its parents. The average retention rate of B. napus JmjC gene from B. rapa (93.1%) and B. oleracea (82.6%) exceeded that of all homologous gene pairs (83.7%) across the whole B. napus genome. Thirteen new or duplicated JmjC genes have emerged in B. napus. Sequence similarity and domain organization analyses suggest that the functions of these genes might be diversified. Furthermore, KDM5 genes were examined under stress conditions due to H3K4 demethylation. Expression profiles indicated that the genes from B. napus are possibly involved in various stress responses. Conclusion: This study provides the first genome-wide characterization of JmjC genes in Brassica species. Its JmjC genes potentially have diverse functions, and its KDM5 genes might be involved in stress response. The results of this study facilitate the future functional characterization of the demethylation of JmjC family in Brassica crops.
Fast analysis of a compound large reflector antenna

The offset Gregorian dual reflector antenna is eminently well suited to a radio telescope antenna application as it offers a narrow beam width pattern (i.e high gain) and good efficiency. The focus of this work is on the analysis of characteristics of such a Gregorian antenna. The design of the class of reflector antennas is normally based on the use of ray-optics, with this simplified approach being able to predict antenna performance based on approximate formulas for example the beam width against aperture size. However for compound antennas such as the Gregorian reflector there are several interdependent parameters that can be varied and this reduces the applicability of the simple ray-optic approach. It was decided that, if a fast enough analysis of a configuration can be found, the technique of design through interactive analysis would be viable. To implement a fast analysis of the main beam performance of such a Gregorian antenna, a solution algorithm has been implemented using a plane wave spectrum approach combined with a custom aperture integration formulation. As this is able to predict the beam performance within about a second on a PC, it is suitable for iterative design. To implement the iterative design in a practical manner a user interface has been generated that allows the user to interactively modify the geometry, see the physical layout, and then find the antenna pattern. A complete working system has been realised with results comparing well to a reference solution. The limitations of the technique, such as its inaccuracy in predicting the side lobe structure, are also discussed. ii Stellenbosch University http://scholar.sun.ac.za
Nineteen-Element Phased-Array Feed Development and Analysis on Effects of Focal Plane Offset and Beam Steering on Sensitivity

NINETEEN-ELEMENT EXPERIMENTAL PHASED ARRAY FEED DEVELOPMENT AND ANALYSIS ON EFFECTS OF FOCAL PLANE OFFSET AND BEAM STEERING ON SENSITIVITY Jacob S. Waldron Department of Electrical & Computer Engineering Master of Science Presented herein is the design and construction process in the expansion of BYU‟s seven-element experimental platform to a nineteen-element platform for phased array feed experiments. The nineteen-element system was deployed at the National Radio Astronomy Observatory (NRAO) in Green Bank West Virginia for use on the Green Bank 20-Meter Telescope. Numerical simulations were performed to determine how sensitivity was affected by electronic beam steering and offset of the phased array feed (PAF) relative to the focal plane of the reflector. These simulated results were then compared to experimental data.
TRANSPORTATION CONTROL EFFECTIVENESS IN OZONE NON-ATTAINMENT AREAS: FINAL REPORT

The main objective of this project is to develop a prototype of an integrated and coordinated regional transportation planning and emissions modeling procedure. The procedure will be flexible in structure to accommodate continual advances in travel demand methods and improvements in the MOBILE model. The need for an integrated and coordinated Transportation Control Measure (TCM) air quality analysis procedure has been emphasized by a review of the state-of-the-art modeling practice used by 41 metropolitan planning organizations (MPOs) and nine states in the country (Chatterjee et al. 1997). The report provides recommendations for improvements in traffic input data for emissions modeling. These recommendations are based on a detailed sensitivity analysis that shows the high sensitivity of the emissions factor model to many input traffic data.
Efficiences of Advanced Waste Treatment Obtained with Upgraded Trickling Filters

Many or most cities and towns, and particularly the smaller ones, still use trickling filters in their wastewater treatment plants. The process is economical and reliable, but unfortunately BOD\d5 and suspended solids removal efficiency in many cases is not high enough to meet today’s effluent quality requirements. But recent experience at Corvallis, Oregon, suggests that trickling filter plants can be upgraded, at relatively low cost to provide effluents of quality equal to advanced secondary treatment or even of advanced waste treatment (effluent BOD\d5 and SS less than 10 mg/l). Because of its relatively low cost and potential broad applicability, the innovation is thought to be very significant.
Compare of Sequential, Delayed and Simultaneous Resection Strategies for Synchronous Colorectal Liver Metastases

Background: The present study aimed to compare perioperative safety and long-term survival of patients with synchronous colorectal liver metastases receiving sequential resection (SeR), delayed resection (DeR) and simultaneous resection (SiR). Methods: From January 2007 to December 2016, data of patients receiving surgery at Peking University Cancer Hospital for synchronous colorectal liver metastases were retrospectively collected. The above three different surgical strategies were compared. Results: A total of 233 cases were included, with 49 in the SeR group, 98 in the DeR group and 86 in the SiR group. The incidence of severe complications was 26.7% in the SiR group, higher than that in the DeR group (11.2%, p=0.007) and the SeR group (16.3%, p=0.166). Overall survival at 1-year and 3-year in the SeR group (93.9% and 50.1%) was lower than the DeR group (94.9% and 64.8%, p=0.019), but not statistically different compared with the SiR group (93.0% and 55.2%, p=0.378). Recurrence-free survival at 1-year and 3-year in the SeR group (22.4% and 18.4%) was lower than the DeR group (43.9% and 24.2%, p=0.033), but not statistically different compared with the SiR group (31.4% and 19.6%, p=0.275). Cox multivariate analysis indicated that T4, lymph node positive primary tumor, liver metastases>30mm and selective sequential resection (compared with delayed resection) were correlated with poor prognosis. Conclusion: Simultaneous resection has a relatively higher incidence of severe complication, and when staged resection strategy was made, the prognosis of delayed resection was better than that of sequential resection.
Wool characteristics in the Meat and wool New Zealand Central Progeny Test flocks

The Meat and Wool New Zealand Central Progeny Test programme (CPT) was established to demonstrate the relative breeding merit of leading sires in the New Zealand sheep industry. Here we describe the wool grown over the summer by the 2007 born one-year-old ewes within the CPT. Within fleeces, staple strength varied between farms as shown by the mean difference of 23 N/ktex in offspring of the link sire. Staple strength correlated positively with midside fibre diameter (r = 0.26), medullation (r = 0.23) and negatively with fibre curvature (r = -0.61). Staple strength was similar on anterior (74 ± 24 N/ktex) and midside (75 ± 24 N/ktex) body-sites, but was weaker on the hindleg (64 ± 21 N/ktex; P <0.001). Overall mean staple strength was 72 ± 20 N/ktex, while individual fleeces ranged from 19 to 121 N/ktex. Ten percent of fleeces measured below 45 N/ktex leaving them prone to excessive fibre breakage during processing. Some fleeces varied up to 40 N/ktex across body-sites. Even within one flock, offspring of individual sires differed by a mean of 29 N/ktex, suggesting a consistent weakness of wool in the progeny of some highly ranked sires which will negatively affect processing and end-product performance.
Asymmetry in Earnings Management Surrounding Targeted Ratings

This study investigates asymmetric incentives in firms managing earnings in an attempt to achieve a target financial strength rating. We find empirical evidence that firms with an actual rating below their target rating use income-increasing earnings management. However, we find no evidence that firms above their target rating manage earnings. Our findings are robust to a variety of alternative definitions of target rating. We additionally find evidence that this earnings management can be mitigated through external monitoring. These findings indicate that firms have incentives to reach a target rating if they are rated below their target, but not above their target.
Supporting Intelligibility in a Healthcare scenario using Palcom

In this paper we describe a scenario for supporting healthcare at home and identify some demands for intelligibility in this situation. In such a system we have identified a need for flexible adding and removing medical devices, and to support changing functionality depending on if a nurse is present or not. We suggest that this kind of variability can be addressed by introducing guards in our rule based formulation. and sketch a way it can be solved. The scenario we describe comes from an ongoing project in developing support
Diabetes and Motor Vehicle Crashes: A Systematic Evidence-Based Review and Meta-Analysis

The primary objective of this systematic review was to address the question, “Are drivers with diabetes mellitus at greater risk for a motor vehicle crash than comparable drivers without the disease? ” and secondarily, to address the question, “Are insulin-treated diabetics at higher risk for crash? ” The authors' searches identified 16 articles that addressed these questions. An assessment of study quality of the included studies found them to be in the low-to-moderate range. While attempts were made to control for differences in the characteristics of individuals that may confound the relationship between diabetes and crash risk in all included studies, most failed to control for exposure. A random-effects meta-analysis found that individuals with diabetes have a 19% increased risk for a motor vehicle crash when compared to similar individuals without diabetes. The authors found no compelling evidence to suggest that insulin-treated individuals are at higher risk for motor vehicle crash than individuals with diabetes not being treated with insulin. The authors discuss the implications of these findings.
Reducing Learning Object Inspection/Evaluation Costs in Instructional Design

REDUCING LEARNING OBJECT INSPECTION/EVALUATION COSTS IN INSTRUCTIONAL DESIGN Larry L. Seawright Department of Instructional Psychology & Technology Doctor of Philosophy A widely employed instructional design approach, the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, has been one of the most popular and well documented instructional design models (Wilson, Jonassen, and Cole, 1993) for decades. Despite its widespread use, Thiagarajan, a leading instructional technologist, asserts that ADDIE, as an instructional design approach, is comparable to an outdated 1950's manufacturing model (Zemke, 2002). Since the 1950's, manufacturing has evolved, focusing initially on reducing inspection or evaluation costs and later on shifting these cost improvements throughout the organization. Just as manufacturing models and their application have evolved, service operations models such as instructional design models and especially their application are evolving. This dissertation reviews these changes in manufacturing models and associated service operations models in order to examine how these changes have informed instructional design models such as ADDIE and their usage in practice by those attempting to design conditions for learning and to create associated learning objects. In order to better understand how this shift may be applied to both theory and practice in instructional design, this dissertation uses an exploratory case study methodology to examine best practices in the inspection/evaluation process employed during the development of courses. This methodology reflects procedures used in a major study (Institute for Higher Education Policy, 2000). They followed a three-step process, which included a comprehensive literature review, the identification of subjects that "have substantial experience and are providing leadership in distance education. " (p.9), and surveying leaders. In similar fashion, during the first phase of the study reported in this research, quality management and instructional design literature is reviewed. In the second phase, the case study subject, the Center for Instructional Design at a major university is selected. In the third phase, instructional design practices used at the Center were studied and areas for reducing inspection/evaluation costs were identified. Principles and methods surmised from the literature reviews and the case study research are presented along with application examples from the case study. These principles and methods illustrate how ADDIE has evolved and continues to be a viable model for the creation of instruction.
ROM: A Requirement Opinions Mining Method Preliminary Try Based on Software Review Data

Requirement opinion mining aims to mine user opinions that can be used to help the mining of software requirements from various data sources. However, in the development of social network systems, software application platforms or stores and other data sources, the massive, noisy, non-standard data, makes the mining of effective requirement opinions more difficult. Therefore, there is less work in software requirements mining based on the data of software review in development social media or application market. This paper attempts to provide some knowledge support for requirement user story establishing in RE based on the opinion mining and clustering of massively software review data. First of all, this paper combines the requirements of the requirements engineering field to define the requirement opinions, functional requirement opinions and non-functional requirements opinions. Secondly, using the deep learning model to classify the functional requirement reviews and non-functional requirements reviews included in the reviews; Based on the differences between functional data and non-functional data, this paper defines three categories in the description of software functional data, and chooses to use sequence labeling methods to identify functional requirements. Then use the K-means clustering method based on word vector to cluster the review data, and combine TF-IDF and syntactic analysis to extract the aspect and aspect requirements or specific requirements of the requirement opinion respectively, so as to realize the requirement opinion mining of software review data. Finally, this article will give a case study based on the user review data of the mobile phone application service platform 360 mobile assistants.
Predictability of Brayton electric power system performance

Data from the first tests of the 2- to 15-kilowatt space power system in a vacuum chamber were compared with predictions of both a pretest analysis and a modified version of that analysis. The pretest analysis predicted test results with differences of no more than 9 percent of the largest measured value for each quantity. The modified analysis correlated measurements. Differences in conversion efficiency and power output were no greater than plus or minus 2.5 percent. This modified analysis was used to project space performance maps for the current test system.
Embodiment of Spatially Arterial Pulse Diagnostic Apparatus using Array Multiple Hall Devices

The study relates to achievement and analysis of 3-dimensional spatial pulse wave archived by a spatially arterial pulse diagnostic apparatus (SAPDA), wherein a pulse sensing part array consists of multiple hall devices and is located over a skin contacting part which consists of a magnetic material. When a radially arterial pulse is transferred to the magnetic material, which is contacted skin that results in changes in a magnetic field of the lower part of the pulse sensing part array, the changes in a magnetic field can be detected by the commercial Hall semiconductor device of the pulse sensing part array. Finally, according to development of SAPDA, the 3-dimensionally arterial pulse waveform can be measured noninvasively by detecting the changes of the magnetic field.
Definition of the perceived self-care ability in stroke survivors living at home in the Middle East: a protocol for a Systematic Literature Review (Preprint)

BACKGROUND Stroke brings about several adverse outcomes so that a stroke patient faces numerous physical, and sensory together with cognitive, and psychological disorders. These disorders influence patients’ perceived self-care ability. There is no agreement on what the perceived self-care ability in stroke patients living at home is Because of various cultures and medical systems, such an ambiguity may be more serious when it comes to the Middle East countries compared to advanced ones. OBJECTIVE This Systematic Literature Review aims to summarize the literature on this concept and propose a definition which might help similar research on the stroke in the future. METHODS The databases PubMed, Scopus, CINAHL, PsycINFO, PEDro, Web of Science, ProQuest, ScienceDirect, Index Medicus, EMRO, Google Scholar, Magiran, SID, IranDoc, and stroke-related literature will individually be queried to retrieve relevant literature on the perceived self-care ability in stroke patients, using subject headings and appropriate MeSH terms. The inclusion and exclusion criteria will be developed and refined by the research team. Two independent reviewers will participate in each search stage including abstract/title and full-text screening, study selection, data collection, and quality assessment steps. We will restrict our search to articles published in the English language in biomedical journals since 1970 to 2018. RESULTS The result will be tabulated, and meta-synthesis will be performed. CONCLUSIONS This Systematic Literature Review can present a more accurate perception of the perceived self-care ability in stroke survivors living at home in Middle East countries.

Pavement Distress Evaluation using 3D Depth Information from Stereo Vision

During the last few decades, many efforts have been made to produce automatic inspection systems to meet the specific requirements in assessing distress on road surfaces using video cameras and image processing algorithms. However, due to the noisy images from pavement surfaces, limited success was accomplished. One major issue with pure video based systems is their inability to discriminate dark areas not caused by pavement distress, such as, tire marks, oil spills, shadows, and recent fillings. To overcome the limitation of the conventional imaging based methods, a probabilistic relaxation technique based on 3-dimensional (3D) information is proposed in this report. The primary goal of this technique is to integrate conventional image processing techniques with stereovision technology to obtain an accurate topological structure of the road defects. In addition, a road scene often contains other objects such as grass, trees and buildings which should be separated from the pavement. Therefore the earlier algorithm has been enhanced to extract the pavement region from a road scene using a Support Vector Machine (SVM). Various types of cracks are then obtained from the pavement surface images and classified using a feed-forward neural network. The proposed algorithms are implemented in MATLAB and the results are presented. The second half of the document includes a report detailing the development of a software package that would allow the user to review digital photographs of pavement, evaluate that pavement by the PASER method, store the results in a database, and then make decisions based on the results of that analysis. The computer interface and analysis portion of the software was written in Microsoft Visual BASIC 2008. The long-term goals of this project include linking the evaluation results to a geographical information system database and developing various reporting strategies.
Development of Real-Time Load Flow Program for Korean Energy Management System

This paper introduces a real-time load flow program for Korean energy management system(EMS). This study is concentrated on the following aspects. First, we propose the model of the real-time database and power system equipment for the real-time load flow. These models are extracted from the needs of load flow functions and are designed to the application common information. Second, several techniques are applied for the efficient convergence and computational speed. The generation/load mismatch is redistributed using generator participation factors which are separated to the reference bus. For the voltage control, the jacobian matrix is composed with the basic Y matrix elements and the voltage control elements. Through the optimally ordering, jacobian row and column for a column is changed. However all jacobian matrix entries have same order with the Y matrix. The proposed program is tested using the Korea Electric Power Corporation(KEPCO) system. Through the test, we verified that the proposed program can be effectively used to accomplish the Korean EMS system.
