On neural network based online tuning of rolling mill drive armature current Pl-controller parameters

The main tendency of rolling mills drives modernization is outdated analog control systems replacement with new digital ones. At the same time, a power section of the drive remains the same. This gives an opportunity to develop and implement adaptive digital control system for such plants in order to take into consideration their high nonlinearity. Having considered different types of such systems, the ones which does not change the well-accepted PID control algorithm, but tune its parameters KP, KI, KD are believed to have the highest chances to be applied into industry. The main aim of this research is to develop and apply a neural tuner to adjust armature current PI-controller parameters of a two-high reversing rolling mill drive online. The neural tuner consists of 1) a neural network calculating KP and KI values and trained online with the help of backpropagation method and 2) a rule base, which conditions is used to estimate transient quality, whereas consequences are values of a learning rate of the network output layer neurons. Modeling experiments are conducted with a model of the plant under consideration. They are used to check the ability of the tuner to: 1) adjust the PI-controller parameters back to optimal values; 2) cope with an armature winding parameters drift. Such experiments are conducted both for the systems with the neural tuner and a conventional PI-controller. As far as the second type of experiments is concerned, the system with the neural tuner is able to achieve 2% energy consumption decrease comparing to a conventional PI-controller based control system.

A new applicator design for endocavitary brachytherapy of cancer in the nasopharynx.

INTRODUCTION
In attempting to improve local tumor control by higher doses of radiation, there has been a resurgence of interest in the implementation of brachytherapy in the management of primary and recurrent cancers of the nasopharynx. Brachytherapy with its steep dose fall-off is of particular interest because of the proximity of critical dose limiting structures. Recent developments in brachytherapy, such as the introduction of pulsed-dose-rate and high-dose-rate computerized afterloaders, have encouraged further evolution of brachytherapy techniques.


MATERIALS AND METHODS
We have designed an inexpensive, re-usable and flexible silicone applicator, tailored to the shape of the soft tissues of the nasopharynx, which can be used with either low-dose-rate brachytherapy or high (pulsed)-dose-rate remote controlled afterloaders.


RESULTS AND CONCLUSIONS
This Rotterdam nasopharynx applicator proved to be easy to introduce, patient friendly and can remain in situ for the duration of the treatment (2-6 days). The design, technique of application and the first consecutive 5 years of clinical experience in using this applicator are presented.
A mouse radiation-induced liver disease model for stereotactic body radiation therapy validated in patients with hepatocellular carcinoma.

PURPOSE
Lower radiation tolerance of the whole liver hinders dose escalations of stereotactic body radiation therapy (SBRT) in hepatocellular carcinoma (HCC) treatment. This study was conducted to define the exact doses that result in radiation-induced liver disease (RILD) as well as to determine dose constraints for the critical organs at risk (OARs) in mice; these parameters are still undefined in HCC SBRT.


METHODS
This study consisted of two phases. In the primary phase, mice treated with helical tomotherapy-based SBRT were stratified according to escalating radiation doses to the livers. The pathological differences, signs [such as mouse performance status (MPS)], and serum aspartate aminotransferase (AST)/alanine aminotransferase (ALT)/albumin levels were observed. Radiation-induced disease severities of the OARs were scored using systematic evaluation standards. In the validation phase in humans, 13 patients with HCC who had undergone radiotherapy before hepatectomy were enrolled to validate RILD pathological changes in a mouse study.


RESULTS
The evaluation criteria of the mouse liver radiotherapy-related signs were as follows: MPS ≥ 2.0 ± 0.52, AST/ALT ≥ 589.2 ± 118.5/137.4 ± 15.3 U/L, serum albumin ≤ 16.8 ± 2.29 g/L. The preliminary dose constraints of the OARs were also obtained, such as those for the liver (average dose ≤ 26.36 ± 1.71 Gy) and gastrointestinal tract (maximum dose ≤ 22.63 Gy). Mouse RILD models were able to be developed when the livers were irradiated with average doses of ≥31.76 ± 1.94 Gy (single fraction). RILD pathological changes in mice have also been validated in HCC patients.


CONCLUSIONS
Mouse RILD models could be developed with SBRT based on the dose constraints for the OARs and evaluation criteria of mouse liver radiotherapy-related signs, and the authors' results favor the study of further approaches to treat HCC with SBRT.
Federation, Democracy and the Struggle against a Single Australia

Abstract One of the essential characteristics of modern nationhood is singularity. There is one Australia, with one story, one foundation, one destiny and one face to the world at large. However, singularity limits good history. It makes a particularly strong impact on our understanding of those episodes which seem to be crucial turning points in the history of the nation, including in Australia's case the period of federation and World War One. Good accounts of that period, and thus of the whole Australian experience, depend on avoiding the seductions of singularity, and the impact on scholarship of ‘the lethal chimera of the modern nation-state’.
Effect of 5α-Reductase Inhibitors on Sexual Function: A Meta-Analysis and Systematic Review of Randomized Controlled Trials.

INTRODUCTION
5α-Reductase inhibitors (5ARIs) are widely used for the treatment of benign prostatic hyperplasia (BPH) and androgenetic alopecia (AGA).


AIM
To review all the available data on the effect of 5ARIs on sexual function and assess whether 5ARIs increase the risk of sexual dysfunction.


METHODS
A systematic search of the literature was conducted using the Medline, Embase, and Cochrane databases. The search was limited to articles published in English and up to October 2015. Article selection proceeded according to the search strategy based on Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. Data were analyzed using Stata 12.0. A fixed- or a random-effects model was used to calculate the overall combined risk estimates. Publication bias was assessed using Begg and Egger tests.


MAIN OUTCOME MEASURES
Sexual dysfunction, erectile dysfunction, and decreased libido.


RESULTS
After screening 493 articles, 17 randomized controlled trials with 17,494 patients were included. Nine studies evaluated the efficacy of 5ARIs in men with BPH. The other eight reported using 5ARIs in the treatment of men with AGA. The mean age of participants was 60.10 years across all studies. We included 10 trials (6,779 patients) on the efficacy and safety of finasteride, 4 trials (6,222 patients) on the safety and tolerability of dutasteride, and 3 trials (4,493 patients) using finasteride and dutasteride for AGA. The pooled relative risks for sexual dysfunction were 2.56 (95% CI = 1.48-4.42) in men with BPH and 1.21 (95% CI = 0.85-1.72) in men with AGA; those for erectile dysfunction were 1.55 (95% CI = 1.14-2.12) in men with BPH and 0.66 (95% CI = 0.20-2.25) in men with AGA; and those for decreased libido were 1.69 (95% CI = 1.03-2.79) in men with BPH and 1.16 (95% CI = 0.50-2.72) in men with AGA. Estimates of the total effects were generally consistent with the sensitivity analysis. No evidence of publication bias was observed.


CONCLUSION
Evidence from the randomized controlled trials suggested that 5ARIs were associated with increased adverse effects on sexual function in men with BPH compared with placebo. However, the association was not statistically significant in men with AGA. Well-designed randomized controlled trials are indicated to study further the mechanism and effects of 5ARIs on sexual function.
TOPOLOGY CONTROL IN MOBILE AD HOC NETWORKS WITH COOPERATIVE COMMUNICATIONS

Cooperative communication has received tremendous interest for wireless networks. Most existing works on cooperative communications are focused on link-level physical layer issues. Consequently, the impacts of cooperative communications on network-level upper layer issues, such as topology control, routing and network capacity, are largely ignored. In this article, we propose a Capacity-Optimized Cooperative (COCO) topology control scheme to improve the network capacity in MANETs by jointly considering both upper layer network capacity and physical layer cooperative communications. Through simulations, we show that physical layer cooperative communications have significant impacts on the network capacity, and the proposed topology control scheme can substantially improve the network capacity in MANETs with cooperative communications.

Racial/ethnic differences in bone mineral density among older women

The epidemiologic information regarding international differences in bone mineral density (BMD) in women is currently insufficient. We compared BMD in older women across five racial/ethnic groups in four countries. The femoral neck, total hip, and lumbar spine BMD were measured in women (aged 65–74 years) from the Study of Osteoporotic Fractures (SOF) (5,035 Caucasian women and 256 African American women in the US), the Tobago Women’s Health Study (116 Afro-Caribbean women), the Ms Os Hong Kong Study (794 Hong Kong Chinese women) and the Namwon Study (1,377 South Korean women). BMD was corrected according to the cross-site calibration results for all scanners. When compared with US Caucasian women, the age adjusted mean BMD measurements at the hip sites were 21–31 % higher among Tobago Afro-Caribbean women and 13–23 % higher among African American women. The total hip and spine BMD values were 4–5 % lower among Hong Kong Chinese women and 4–7 % lower among South Korean women compared to US Caucasians. The femoral neck BMD was similar in Hong Kong Chinese women, but higher among South Korean women compared to US Caucasians. Current/past estrogen use was a significant contributing factor to the difference in BMD between US versus non-US women. Differences in body weight partially explained the difference in BMD between Asian versus non-Asian women. These findings show substantial racial/ethnic differences in BMD even within African or Asian origin individuals, and highlight the contributing role of body weight and estrogen use to the geographic and racial/ethnic variation in BMD.
Linking ecological and built components of urban mosaics: an open cycle of ecological design

1. By the end of this decade, the majority of people will live in cities and suburban areas. Urban areas, including suburbs and exurbs, are expanding rapidly worldwide. 2. Plant ecology has largely ignored cities, or has primarily focused on the discrete urban green spaces within cities. 3. Plant ecology is increasingly engaging urban ecosystems as integrated natural-human systems, in which human agency is part of the complex of feedbacks. 4. Linking plant ecology with urban design (architecture, landscape architecture, civil engineering and urban planning) can help to integrate research and understanding of plants into the structure of cities, and to make use of urban design projects as ecological research tools. 5. Synthesis . A cycle of ecological design illustrates the linkage of plant ecological research with the ongoing transformation of urban systems by urban designers and civil society. Quality of life, human health, public appreciation of ecological processes in cities, and scientific understanding can all be enhanced by participating in a cycle of ecological urban design.

Vocaine the vocoder and applications in speech synthesis

Vocoders received renewed attention recently as basic components in speech synthesis applications such as voice transformation, voice conversion and statistical parametric speech synthesis. This paper presents a new vocoder synthesizer, referred to as Vocaine, that features a novel Amplitude Modulated-Frequency Modulated (AM-FM) speech model, a new way to synthesize non-stationary sinusoids using quadratic phase splines and a super fast cosine generator. Extensive evaluations are made against several state-of-the-art methods in Copy-Synthesis and Text-To-Speech synthesis experiments. Vocaine matches or outperforms STRAIGHT in Copy-Synthesis experiments and outperforms our baseline real-time optimized Mixed-Excitation vocoder with the same computational cost. We report that Vocaine considerably improves our statistical TTS synthesizers and that our new statistical parametric synthesizer [1] matched the quality of our mature production Unit-Selection system with uncompressed waveforms.
3 D Object Detection with a Deformable 3 D Cuboid Model

This paper addresses the problem of category-level 3D object detection. Given a monocular image, our aim is to localize the objects in 3D by enclosing them with tight oriented 3D bounding boxes. We propose a novel approach that extends the deformable part-based model [1] to reason in 3D. Our model represents an object class as a deformable 3D cuboid composed of faces and parts, which are both allowed to deform with respect to their anchors on the 3D box. We model the appearance of each face in fronto-parallel coordinates, thus effectively factoring out the appearance variation induced by viewpoint. We train the cuboid model jointly and discriminatively. In inference we slide and rotate the box in 3D to score the object hypotheses. We evaluate our approach in indoor and outdoor scenarios, and show that our approach outperforms the state-of-the-art in both 2D [1] and 3D object detection [3].
Vascular Function and Uric Acid-Lowering in Stage 3 CKD.

Hyperuricemia may contribute to endothelial dysfunction in CKD. We evaluated whether lowering serum uric acid levels with allopurinol improves endothelial dysfunction in 80 participants ≥18 years of age with stage 3 CKD and asymptomatic hyperuricemia (≥7 mg/dl in men and ≥6 mg/dl in women) randomized in a double-blinded manner to receive placebo or allopurinol for 12 weeks. Randomization was stratified according to presence or absence of diabetes mellitus. We measured vascular endothelial function by brachial artery flow-mediated dilation. No significant differences existed between groups at baseline; 61% of the participants had diabetes mellitus in both groups. The placebo and the allopurinol groups had baseline serum uric acid levels (SDs) of 8.7 (1.6) mg/dl and 8.3 (1.4) mg/dl, respectively, and baseline flow-mediated dilation values (SDs) of 6.0% (5.0%) and 4.8% (5.0%), respectively. Compared with placebo, allopurinol lowered serum uric acid significantly but did not improve endothelial function. In participants without diabetes mellitus, allopurinol associated with a trend toward improved flow-mediated dilation (+1.4% [3.9%] versus -0.7% [4.1%] with placebo), but this was not statistically significant (P=0.26). Furthermore, we did not detect significant differences between groups in BP or serum levels of markers of inflammation and oxidative stress. In conclusion, allopurinol effectively and safely lowered serum uric acid levels in adults with stage 3 CKD and asymptomatic hyperuricemia but did not improve endothelial function in this sample of patients.
Parallel implementation of the quadratic sieve

A new version of the Quadratic Sieve algorithm, used for factoring large integers, has recently emerged. The new algorithm, called the Multiple Polynomial Quadratic Sieve, not only considerably improves the original Quadratic Sieve but also adds features that ideally suit a parallel implementation. The parallel implementation used for the new algorithm, a novel remote batching system, is also described.
A fuzzy ServQual based method for reliable measurements of education quality in Italian higher education area

In recent years, the attention that the European Community has focused on the education sector has produced a new university commitment addressed to quality aspects for all education related services. In fact, a quality oriented service requires excellence in the design and planning of service activities, as well as during its delivering and also for the adopted service performance evaluation method. However, considering that service performance evaluations are deeply based on stakeholders’ judgments, they can be characterized by possible uncertainties related to incompleteness for partial ignorance, imprecision for subjectivity and even vagueness. Therefore, under these conditions, unreliable results can be obtained by widely considered service analysis methods. In the present paper, a method based on a recent extension of the ServQual model and that uses in combined manner the Fuzzy Set Theory and the Analytic Hierarchy Process method is proposed to effectively handle uncertainty in service performance analyses. In particular, the Fuzzy Set Theory is considered to deal with such uncertainty, whereas the AHP method is adopted as tool to estimate the importance weights of the strategic service attributes. Subsequently, the strategic analysis of the service value tree related to the Management Engineering program at the University of Palermo (Italy) is performed by using the proposed method. The performed service analysis allows the most influencing service performance factors to be captured and commented upon. Finally, the obtained results show that the professors’ perception of service quality meaningfully influences the overall service performance level. 2013 Elsevier Ltd. All rights reserved.
Weight-based dosing of enoxaparin in obese patients with non-ST-segment elevation acute coronary syndromes: results from the CRUSADE initiative.

STUDY OBJECTIVE
To evaluate how enoxaparin is dosed in contemporary clinical practice as a function of patients' total body weight (TBW) and body mass index (BMI), and to determine any association between dose and major bleeding.


DESIGN
Retrospective cohort study.


DATA SOURCE
The Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the American College of Cardiology-American Heart Association Guidelines (CRUSADE) national quality improvement initiative database.


PATIENTS
A total of 19,061 patients enrolled in the CRUSADE initiative between January 1, 2004, and March 31, 2006, who received enoxaparin for the initial treatment of non-ST-segment elevation acute coronary syndromes.


MEASUREMENTS AND MAIN RESULTS
Demographic and clinical data, enoxaparin doses, and frequency of major bleeding unrelated to coronary artery bypass graft (CABG) surgery were compared among patient groups stratified by TBW(< or = 100, 101-120, 121-150, and > 150 kg). Adjusted odds ratios (OR) of major bleeding unrelated to CABG surgery were calculated with each dose increase of 0.25 mg/kg stratified by BMI (< 18.5, 18.5-24.9, 25.0-29.9, and > or = 30 kg/m(2)), as well as for patients receiving a reduced dose (< 0.95 mg/kg) compared with those receiving a recommended dose (0.95-1.05 mg/kg), stratified by TBW. An inverse association was noted between enoxaparin dose and patient weight. Median initial doses were 1 mg/kg in those weighing 100 kg or less, 0.96 mg/kg in those 101-120 kg, 0.92 mg/kg in those 121-150 kg, and 0.65 mg/kg in those weighing more than 150 kg (p<0.0001 for < or = 100 kg vs > 150 kg). Up to 80% of patients weighing more than 150 kg received an initial enoxaparin dose below the recommended dose. In contrast to patients with normal body weight, those weighing more than 150 kg who received a recommended dose of enoxaparin had a higher bleeding risk relative to those who received a lower dose (adjusted OR 2.42, 95% confidence interval 0.70-8.37).


CONCLUSION
Clinicians tend to use reduced weight-based doses of enoxaparin in overweight and obese patients. Although data are limited, use of the recommended enoxaparin dose of 1 mg/kg is associated with a higher bleeding risk in those weighing more than 150 kg. Thus, further study of enoxaparin dosing in very obese patients with non-ST-segment elevation acute coronary syndromes is warranted.
Expressing an Image Stream with a Sequence of Natural Sentences

We propose an approach for retrieving a sequence of natural sentences for an image stream. Since general users often take a series of pictures on their special moments, it would better take into consideration of the whole image stream to produce natural language descriptions. While almost all previous studies have dealt with the relation between a single image and a single natural sentence, our work extends both input and output dimension to a sequence of images and a sequence of sentences. To this end, we design a multimodal architecture called coherence recurrent convolutional network (CRCN), which consists of convolutional neural networks, bidirectional recurrent neural networks, and an entity-based local coherence model. Our approach directly learns from vast user-generated resource of blog posts as text-image parallel training data. We demonstrate that our approach outperforms other state-of-the-art candidate methods, using both quantitative measures (e.g. BLEU and top-K recall) and user studies via Amazon Mechanical Turk.
Extended Life

This paper reformulates some of the questions raised by extended mind theorists from an enactive, life/ mind continuity perspective. Because of its reliance on concepts such as autopoiesis, the enactive approach has been deemed internalist and thus incompatible with the extended mind hypothesis. This paper answers this criticism by showing (1) that the relation between organism and cogniser is not one of co-extension, (2) that cognition is a relational phenomenon and thereby has no location, and (3) that the individuality of a cogniser is inevitably linked with the question of its autonomy, a question ignored by the extended mind hypothesis but for which the enactive approach proposes a precise, operational, albeit non-functionalist answer. The paper raises a pespective of embedded and intersecting forms of autonomous identity generation, some of which correspond to the canonical cases discussed in the extended mind literature, but on the whole of wider generality. In addressing these issues, this paper proposes unbiased, non-species specific definitions of cognition, agency and mediation, thus filling in gaps in the extended mind debates that have led to paradoxical situations and a problematic over-reliance on intutions about what counts as cognitive.
