Improved Recommendation Sorting of Collaborative Filtering Algorithm

The traditional collaborative filtering algorithm has no overall quantitative understanding on users' preference. This paper proposes a collaborative filtering algorithm based on improved recommendation sorting. Based on the traditional collaborative filtering rating prediction, three kinds of weighted sorting strategies are proposed to recommendation list, which are based on the combination of users' preference vector and item quality. Experiments on the MovieLens data set show that, in the same rating prediction process, the recommended results of the improved sorting have a significant increase of nearly one time in the precision, recall and F1 indicators.
Biostimulation in primiparous postpartum acyclic early weaned beef cows: introducing the bulls at weaning advances cyclic rebreeding

Weaning and biostimulation promote an early cyclic postpartum rebreeding. Although the signals and mechanisms by which weaning and biostimulation differ, both end stimulating LH secretion. The aim of the experiment was to determine if weaning and biostimulation have additive effects advancing the postpartum rebreeding in primiparous postpartum anoestrous cows. The experiment was performed during late spring – early summer with 51 primiparous Hereford cows. Six weeks after parturition calves were weaned, and cows were managed in two experimental groups: WB (n = 22) and WDB (n = 29). Bulls were joined with WB cows at weaning, but joining was delayed one week in WDB cows. The presence of corpora lutea in the ovaries was recorded weekly with ultrasound, and 28 and 50 days after the end of the exposure period, pregnancy was determined by ultrasound. The percentage of cyclic cows was greater in WB than in WDB on Weeks 8 (36.4 vs 0%), 9 68.2 vs 13.8%), 10 (86.4 vs 27.6%) and 11 (100.0 vs 37.9%) (P < 0.001 in all). Cows that were weaned and biostimulated simultaneously rebred earlier than WDB cows (Week 9.1 ± 0.2 vs Week 11.0 ± 0.2; P < 0.0001). At the end of the experiment 46/51 (90.2%) of the animals were cycling. Pregnancy rate tended to be greater in WB than WDB cows 28 days after the end of the breeding period 18/22 vs 17/29, P = 0.077), but there was no difference at the end of the study (20/22 vs 24/29, ns). In conclusion, the application of weaning and biostimulation simultaneously advances postpartum rebreeding more than weaning alone in beef cows.
Programming .Net Security

With the spread of web-enabled desktop clients and web-server based applications, developers can no longer afford to treat security as an afterthought. It's one topic, in fact, that . NET forces you to address, since Microsoft has placed security-related features at the core of the . NET Framework. Yet, because a developer's carelessness or lack of experience can still allow a program to be used in an unintended way, Programming . NET Security shows you how the various tools will help you write secure applications.
An OpenCL design of the Bob Jenkins lookup3 hash function using the Xilinx SDAccel Development Environment

We report on the implementation of an OpenCL-based design of the Bob Jenkins lookup3 hash function application on the Virtex 7-based ADM-PCIE-7V3 platform using the new Xilinx SDAccel TM development environment. In particular, we demonstrate how to exploit features of the OpenCL programming model available through SDAccel to improve performance by up to 3.5x relative to a naive OpenCL design of the application. Our early-stage results strongly indicate that near-optimal high performance, low-energy software deﬁned solutions on FPGAs can be delivered using SDAccel’s OpenCL development environment with much shorter turnaround times than through hardware-centric RTL ﬂows.
Modal sense classification with task-specific context embeddings

Sense disambiguation of modal constructions is a crucial part of natural language understanding. Framed as a supervised learning task, this problem heavily depends on an adequate feature representation of the modal verb context. Inspired by recent work on general word sense disambiguation, we propose a simple approach of modal sense classification in which standard shallow features are enhanced with task-specific context embedding features. Comprehensive experiments show that these enriched contextual representations fed into a simple SVM model lead to significant classification gains over shallow feature sets.
A vision-based road edge detection algorithm

In the paper, a road edge identification algorithm is developed. The new idea of this method is to use natural road edge, as well as the white strip for road information acquisition. The natural road edge does not be easily polluted like the white lane maker does, so it indicates better adaptability to the outdoor environment. In the algorithm, we use both the pixel feature and the frame feature to identify the road edge, which is referred to as the whole road model. Because several road constrains is used to ensure the road edge detection, the algorithm is immune to the influence of the image disturbance. The algorithm of the road edge identification includes two stages: initialization detection and tracing detection. The initialization stage detects the road edge from the whole road image. The trace algorithm uses the region of interest (ROI) to limit detecting area, which can save much time. In order to give a measure of the reliability of the road detecting result, this paper presents a road edge identification estimation function, which can estimate the reliability of the road edge.
The Application of M-Ary Quantum Evolutionary Algorithm in Bit and Power Allocation for OFDM System over the Power Line

Adaptive resource allocation in orthogonal frequency division multiplexing (OFDM) systems is a very promising technique to improve spectral efficiency. According to actual transmission behavior of the channel environment over low voltage power line, M-ary Quantum Evolutionary Algorithm (MQEA) is proposed to allocate bit and power on different sub-carrier channel, which maximizes the total data rate of the system in a downlink transmission with a total power and bit-error rate(BER) constraints. Simulation results show that the proposed algorithm achieve a higher data rate.
Participants’ perspectives and preferences on clinical trial result dissemination: The TRUST Thyroid Trial experience

Background: While there is an increasing consensus that clinical trial results should be shared with trial participants, there is a lack of evidence on the most appropriate methods. The aim of this Study Within A Trial (SWAT) is to use a patient and public involvement (PPI) approach to identify, develop and evaluate a patient-based approach to receiving trial results for participants in the Thyroid Hormone Replacement for Subclinical Hypo-Thyroidism Trial (TRUST), a trial of thyroxine versus placebo in people aged 65 years and older. Methods: Mixed methods study with three consecutive phases. Phase 1 iteratively developed a patient-based approach using semi-structured focus groups and a consensus-orientated-decision model, a PPI group to refine the method and adult literacy review for plain English assessment. Phase 2 was a single-blind parallel group trial. Irish TRUST participants were randomised to the intervention (patient-based approach) and control group (standard approach developed by lead study site). Phase 3 used a patient understanding questionnaire to compare patient understanding of results between the two groups. Results: Participants want to receive results of clinical trials, with qualitative findings indicating three key themes including ‘acknowledgement of individual contribution’, ‘contributing for a collective benefit’ and ‘receiving accessible and easy to understand results’. Building on these findings, the patient-based approachwas developed. TRUST participants (n=101) were randomised to the intervention (n=51) or control group (n=50). The questionnaire response rate was 74% for the intervention group and 62% for the control group. There were no differences in patient understanding between the two approaches. Conclusions: We have demonstrated that it is feasible to involve trial participants in the development of result dissemination materials. Although, in this study PPI did not influence patients’ understanding of results, it documents the process of conducting PPI within the clinical trial setting.
Understanding single-Event effects in FPGA for Avionic system design

Abstract Radiation has proven to cause transient and permanent failures in the semiconductors. When an energetic radiation particle strikes the semiconductor substrate, single-event effects (SEEs) occur. The effects due to SEE are prime areas of research and various experiments have been conducted to study the effects through artificial radiation environment. Radiation effects in avionics systems are gaining more attention since they are used to perform safety critical functions at higher altitudes. In this paper, a comprehensive review on the topic of SEEs on electronics, with special emphasis on its effects on field-programmable gate array (FPGA) is presented. This bibliographical survey covers most of the state-of-the-art technologies used in the prevention and mitigation techniques in FPGA design and also briefs the standards used for managing SEE in avionics. A detailed description of radiation experiments, their test setups and analysis are not included as they are beyond the scope of this review; instead, it gives a design perspective in a radiation environment.
PUBLIC PERCEPTIONS OF GENETICALLY MODIFIED FOODS: A NATIONAL STUDY OF AMERICAN KNOWLEDGE AND OPINION

This report presents the results from the second phase of a longitudinal study of Americans' knowledge and feelings about agricultural biotechnology and how those perceptions and attitudes have changed over time. Two independent national probability samples of 1,200 adults were interviewed by phone in the spring of 2001 and 2003. While this report focuses on the findings from 2003, longitudinal comparisons are presented where appropriate. The report begins with an investigation of Americans' awareness of the presence of genetically modified (GM) ingredients in the foods they encounter everyday. Next, the report describes Americans' actual and perceived knowledge of science, biotechnology and food production. It then examines American opinions about GM foods in general, along with their opinions on a variety of existing and potential GM food products with direct or indirect consumer benefits. The report discusses the relationship between opinions of GM food and a variety of factors, including demographics, knowledge of biotechnology, purchasing behaviors and styles of food selection. Finally, it describes Americans' thoughts on GM food labeling. Highlights of the findings are below. Americans pay little attention to agricultural biotechnology. - Only half of Americans are aware that foods containing genetically modified (GM) ingredients are currently sold in stores. - Despite the prevalence of such foods, only one-quarter of Americans believe they have eaten them. - Little more than a third of Americans have ever discussed biotechnology. - Awareness, although still low, has increased slightly from 2001. Americans do not have much knowledge about agricultural biotechnology. - Self-reported knowledge of biotechnology is low. - Quizzes on biotechnology and food production reveal that Americans are generally uninformed about both, and this has not changed since 2001. Opinion on the acceptability of GM foods is split. - When asked directly, about half of Americans report that they approve of plant-based GM foods, (down from 2001) and about a quarter approve of animal-based GM foods (unchanged from 2001). - Approximately 10% of Americans report being unsure of their opinion of GM foods. Opinions of GM food are easily influenced. - Approval increases when specific benefits of GM food are mentioned. - Reactions to the technology depends on what it is called. The term biotechnology evokes the most positive responses, while genetic modification is perceived most negatively and genetic engineering is most often associated with cloning. Demographics and styles of choosing food are related to acceptance of GM foods. - Women, people over 64, and people with low levels of education are less likely to approve of GM foods. - People who value naturalness and healthfulness in their foods are slightly less likely to approve of GM foods. - People who have purchased organic foods in the past are less likely to approve of GM foods.

Navigation in Indoor Environments: Does the Type of Visual Learning Stimulus Matter?

This work addresses the impact of a geovisualization’s level of realism on a user’s experience in indoor navigation. The key part of the work is a user study in which participants navigated along a designated evacuation route previously learnt in a virtual tour or traditional 2D floor plan. The efficiency and effectiveness of completing the task was measured by the number of incorrect turns during navigation and completion time. The complexity of mental spatial representations that participants developed before and after navigating the route was also evaluated. The data was obtained using several qualitative and quantitative research methods (mobile eye tracking, structured interviews, sketching of cognitive maps, creation of navigation instructions, and additional questions to evaluate spatial orientation abilities). A total of 36 subjects (17 in the “floor plan” group and 19 in the “virtual tour” group) participated in the study. The results showed that the participants from both groups were able to finish the designated navigation route, but more detailed mental spatial representations were developed by the “virtual tour” group than the “floor plan” group. The participants in the virtual tour group created richer navigation instructions both before and after evacuation, mentioned more landmarks and could recall their characteristics. Visual landmark characteristics available in the virtual tour also seemed to support the correct decision-making.
Novel load-based control strategies for power system primary frequency regulation

Any inequality between power system generation and load must be corrected in a short time, otherwise frequency deviation will happen and consequently the stability and security of the power system will be threatened. Demand-side endpoints are distributed on the load side of power systems in contrast to traditional control resources such as centralized bulk generators. The ability of outright ON/OFF switching devices on the demand side enables the loads to respond faster to system disturbances, compared to most conventional generators. This feature, along with the integration of sensing, computation and communication technologies, makes demand-side resources an ideal candidate in primary frequency regulation. This thesis focuses on controlling power systems using distributed load-side resources. Specifically, it proposes three main solutions to overcome the limitations of decentralized load control approaches: ∗Improved Optimal Load Control (IOLC): We introduce an Improved Optimal Load Control (IOLC) approach by applying a systematic gain-tuning method to the conventional OLC. A joint Non-dominated Sorting Genetic Algorithm-II (NSGA-II) with Fuzzy Selection Algorithm (FSA) is employed as the multi objective gain-tuning procedure in IOLC approach. We show by simulation that in comparison with OLC, IOLC can achieve a better generalization performance in the case of turbine-governor (TG) control action whether enabled or disabled. ∗Sparse and Resilient Hierarchical Direct Load Control: We design and develop a hierarchical sensor pruning load modulation strategy for primary frequency response improvement and inter-area oscillations damping. The proposed coordinated hierarchical load control structure utilizes both local and distributed wide-area control, where controllers make use of remote measurements and control signals in an optimal sparse wide-area structure. To be precise, device layer deals with demand-response and frequency regulation, while the sparse supervisory layer improves the system’s closed-loop performance and stability margins, with simultaneous reduction of the cost of data transfer, communication links and power network complexity. ∗Virtual Inertia-based Load Control: Considering the storage built-in aggregated loads, we extend the conventional load control to enable virtual inertia in low-inertia rate power systems. The virtual inertia-based load control signal therefore minimizes the rate of change of
Alcohol Screening and Brief Intervention (SBI) in Telephonic Employee Assistance Programs

Substantial empirical support exists for alcohol screening and brief intervention (SBI) in medical, but not nonmedical settings. A pre- and postdesign is used to examine the effects of an alcohol SBI program implemented telephonically by Employee Assistance Program (EAP) specialists at OptumHealth Behavioral Solutions. Identification rates of risky alcohol use were significantly higher for the Post-SBI Time Period compared to the Pre-SBI Time Period (7.5% vs. 20.1%, p < .0001). The Post-SBI Time Period compared to the Pre-SBI Time Period also had higher rates of delivering EAP telephonic alcohol education/risk reduction interventions (9.8% vs. 13.3%, p < .05). This study found positive benefits when translating evidence-based alcohol SBI protocol for telephonic EAP.
Intelligente Omgevingen: Ondersteunen van Interacties en Terugkijken op Activiteiten

Intelligente omgevingen (smart environments) bevatten sensor- en AI-technologie die het enerzijds mogelijk maken in real-time ondersteuning te geven aan activiteiten die zich in de slimme omgeving afspelen en anderzijds, door op een of andere wijze wat is waargenomen en wellicht geinterpreteerd op te slaan, geinteresseerden de mogelijkheid te geven te grasduinen in wat is opgenomen, er vragen over te stellen en wellicht door het opgeslagene automatisch geattendeerd te worden op interessante zaken. In dit artikel zullen we invulling geven aan deze gezichtspunten door te kijken naar een Europees 6de Kader Project waaraan onze onderzoeksgroep deelneemt. Dit project, gestart in 2004, is het AMI project, waarbij AMI staat voor Augmented Multi-party Interaction. Uitgangspunt bij dit project zijn interacties die plaatsvinden tijdens vergaderingen. Dit maakt het begrijpelijk dat er niet alleen aandacht wordt besteed aan computerondersteuning van activiteiten, maar ook aandacht aan ondersteuning bij het terugkijken op activiteiten. Raadplegen van tijdens een vergadering geschreven notulen is een voorbeeld van dit terugkijken waarbij echter op geen enkele wijze gebruik wordt gemaakt van de huidige mogelijkheden van sensor- en AI-technologie. In dit artikel zal ingegaan worden op deze mogelijkheden zoals ze vorm krijgen binnen het genoemde AMI project.

Inflammatory bowel disease Cape Town, 1975-1980

Summary Patients with Crohn's disease seen in the Gastro­ intestinal Clinic of GrooteSchuur Hospital between 1975 and 1980 were studied to establish the inci­ dence and clinical features of this disease. There were 117 patients and the mean (± SE M) follow-up was 6,1 ± 0,5 years. Of these patients 72% were White, 37% Coloured and 1% Black. The incidence for the Coloured and White population groups was calculated to be 0,4 and 0,9/100000 per year during 1970-1974 and 1,3 and 1,2/100000 per year during 1975-1980 respectively. In Jews the rates were 5,0 and 7,2/100000 per year forthe two periods. Insufficient data are available to calculate an incidence for the Black population. The disease involved the ileum in 39%, the colon in 17% and both areas in 44% of patients. At presen­ tation 18% of patients had mild, 37% moderate, and 45% severe disease. The severity of symptoms was not related to the extent of the disease. A peri-anal fistula was present in 24% of patients. There was no difference in clinical features between the different population groups. Surgical resection had been performed in 50% of patients and 29% of these had had two or more resections. The surgical rate in the ileitis group was 63%, in the ileocolitis group 49% and in those with colitis 20%. S AIr Med J 1983; 63: 226-229.
