Heart rate and outcomes in patients with heart failure with preserved ejection fraction

Abstract Although elevated resting heart rate is related to poor outcomes in heart failure (HF) with reduced ejection fraction, the association in HF with preserved ejection fraction (HFpEF) remains inconclusive. Therefore, we conducted a dose–response meta-analysis to examine the prognostic role of heart rate in patients with HFpEF. We searched PubMed and Embase databases until April 2017 and manually reviewed the reference lists of relevant literatures. Random effect models were used to pool the study-specific hazard ratio (HR) of outcomes, including all-cause death, cardiovascular death, and HF hospitalization. Six studies with 7 reports were finally included, totaling 14,054 patients with HFpEF. The summary HR (95% confidence interval [CI]) for every 10 beats/minute increment in heart rate was 1.04 (1.02–1.06) for all-cause death, 1.06 (1.02–1.10) for cardiovascular death, and 1.05 (1.01–1.08) for HF hospitalization. Subgroup analyses indicated that these positive relationships were significant in patients with sinus rhythm but not in those with atrial fibrillation. There was also evidence for nonlinear relationship of heart rate with each of the outcomes (All P for nonlinearity < .05). Higher heart rate in sinus rhythm is a risk factor for adverse outcomes in patients with HFpEF. Future trials are required to determine whether heart rate reduction may improve the prognosis of HFpEF.
Wavefront reconstruction with tilt from two shearing interferograms

An algorithm is proposed to reconstruct one-dimensional wavefront on the basis of phase differences from two lateral shearing interferograms with tilt errors using discrete Fourier transform. The influence of the tilt errors in two phase differences is analyzed and the calibration process is illustrated in the presence of noise. The tilt errors can be canceled completely and the evaluated wavefront can be recovered with high accuracy even when the random errors exist. The error propagation of noise is investigated by means of Monte Carlo method, and its stability is presented. Finally, the computer simulation is carried out, the result of which demonstrated the capability of the proposed algorithm.
The Anti-Foundation Axiom in Constructive Set Theories

Intrinsically circular phenomena have come to the attention of researchers in differing fields such as mathematical logic, computer science, artificial intelligence, linguistics, cognitive science, and philosophy. Logicians first explored set theories whose universe contains what are called non-wellfounded sets, or hypersets (cf. [17], [5]). But the area was considered rather exotic until these theories were put to use in developing rigorous accounts of circular notions in computer science (cf. [7]). Instead of the Foundation Axiom these set theories adopt the so-called Anti-Foundation Axiom, AFA, which gives rise to a rich universe of sets. AFA provides an elegant tool for modeling all sorts of circular phenomena. The application areas range from knowledge representation and theoretical economics to the semantics of natural language and programming languages. The subject of hypersets and their applications is thoroughly and timely developed in the book [7] by J. Barwise and L. Moss. While reading [7], I asked myself whether most of the material could be developed on the basis of a constructive universe of hypersets rather than a classical one. My tentative answer is that large chunks of [7] only require constructive set theory. Research in this direction is under way. In the meantime the present paper investigates the strength of AFA

Not lost in translation: writing auditorily presented words at study increases correct recognition “at no cost”

ABSTRACT Previous studies have reported a translation effect in memory, whereby encoding tasks that involve translating between processing domains produce a memory advantage relative to tasks that involve a single domain. We investigated the effects of translation on true and false memories using the Deese/Roediger-McDermott (DRM) procedure [Deese, J. (1959). On the prediction of occurrence of particular verbal intrusions in immediate recall. Journal of Experimental Psychology, 58, 17–22; Roediger, H. L. , III, & McDermott, K. B. (1995). Creating false memories: Remembering words not presented in lists. Journal of Experimental Psychology: Learning, Memory, & Cognition, 21, 803–814]. Translation between modalities enhanced correct recognition but had no effect on false recognition. Results are consistent with previous research showing that correct memory can be enhanced “at no cost” in terms of accuracy. Findings are discussed in terms of understanding the relationship between true and false memories produced by the DRM procedure.
Provisional T-drug-eluting stenting technique for the treatment of bifurcation lesions: clinical, myocardial scintigraphy and (late) coronary angiographic results.

BACKGROUND Treatment of bifurcation stenoses (BS) by percutaneous coronary intervention (PCI) remains challenging, even with drug-eluting stents (DES). We aimed to appraise clinical, myocardial scintigraphy and late (>9 months) exploratory angiographic outcomes of provisional T-stenting in the management of BS. METHODS We enrolled 53 consecutive patients with BS in the proximity of a greater than or equal to 2 mm side branch (SB). The provisional T-technique was performed in all cases, with implantation of DES in the main branch (MB), SB balloon-only dilatation, and final kissing in the event of >50% SB stenosis. Provisional SB-stenting (using another DES) was reserved to cases with persisting >50% stenosis/dissection and reduced TIMI flow. Further kissing inflation was recommended in such patients. Stress/rest single-photon emission computed tomography (MIBI) and coronary angiography follow up were scheduled >6 and 9 months after PCI, respectively. RESULTS Major adverse cardiac events at 14 +/- 3 months occurred in 5 patients (9.4% [95% confidence interval 0.1-17.4%]: 1 (1.9% [0.1-5.8%]) non-Q-wave myocardial infarction for subacute stent thrombosis, 2 (3.8% [0.1-9.0%]) target lesion revascularizations and 2 (3.8% [0.1-9.0%]) target vessel revascularizations. Six-month MIBI was performed in 51 patients (96.3%): 4 patients had positive results (7.8% [0.2-15.4%]). Angiography was performed in 4 of these patients and in another 27 patients, with clinical restenosis occurring overall in only 5 (16.1% [8.9-23.3%]), 1 case of clinical restenosis in the MB (3.2% [0.6-9.4%]), and 4 in the SB (12.9% [5.1-24.9%]). CONCLUSIONS This study suggests the safety and efficacy of provisional T-drug-eluting stent implantation in bifurcation coronary lesions, and supports the use of follow-up myocardial scintigraphy, with angiography reserved for selected patients and lesions.
Impact of Base Station Locations and Antenna Orientations on UMTS Radio Network Capacity and Coverage Evolution

The aim of this paper is to study the impact of the base station site locations and antenna orientations on UMTS radio network performance under different traffic distributions, and to find an optimum deployment strategy from 3-sectored to 6-sectored site solutions. A radio network planning tool has been used to verify the radio network system performance of different network scenarios. The results show that UMTS network is fairly robust for small base station site location and antenna orientation deviations. Furthermore, the results indicate that in UMTS radio network planning, the concentration should be paid rather on the base station site and antenna configurations than on base station location. According to the simulations, the most efficient 6sectored capacity and coverage network configuration can be achieved by utilizing horizontally 33° half power narrow beam antennas.
Fast Parameter Estimation in Image Restoration Based on Hierarchical Bayesian Framework

In this paper, an algorithm under Bayesian framework is proposed using the variational method to estimate the original image and parameters simultaneously and iteratively. The harmonic model and the gamma model are introduced as prior models for the original image and parameters separately. The harmonic model is a kind of smoothing model which is computationally efficient compared with nonlinear models, and it can preserve edges in the image better than most other smoothing models. The gamma can incorporate more prior knowledge for than the way that supposes the parameters as certain constants. The experimental results show the competitive performance of the proposed algorithm when used to estimate the parameters.
Seeing It All: Evaluating Supervised Machine Learning Methods for the Classification of Diverse Otariid Behaviours

Constructing activity budgets for marine animals when they are at sea and cannot be directly observed is challenging, but recent advances in bio-logging technology offer solutions to this problem. Accelerometers can potentially identify a wide range of behaviours for animals based on unique patterns of acceleration. However, when analysing data derived from accelerometers, there are many statistical techniques available which when applied to different data sets produce different classification accuracies. We investigated a selection of supervised machine learning methods for interpreting behavioural data from captive otariids (fur seals and sea lions). We conducted controlled experiments with 12 seals, where their behaviours were filmed while they were wearing 3-axis accelerometers. From video we identified 26 behaviours that could be grouped into one of four categories (foraging, resting, travelling and grooming) representing key behaviour states for wild seals. We used data from 10 seals to train four predictive classification models: stochastic gradient boosting (GBM), random forests, support vector machine using four different kernels and a baseline model: penalised logistic regression. We then took the best parameters from each model and cross-validated the results on the two seals unseen so far. We also investigated the influence of feature statistics (describing some characteristic of the seal), testing the models both with and without these. Cross-validation accuracies were lower than training accuracy, but the SVM with a polynomial kernel was still able to classify seal behaviour with high accuracy (>70%). Adding feature statistics improved accuracies across all models tested. Most categories of behaviour -resting, grooming and feeding—were all predicted with reasonable accuracy (52–81%) by the SVM while travelling was poorly categorised (31–41%). These results show that model selection is important when classifying behaviour and that by using animal characteristics we can strengthen the overall accuracy.
Predicting Controversial News Using Facebook Reactions

Different events and their re- ception in different reader communities may give rise to controversy. We pro- pose a distant supervised entropy-based model that uses Facebook reactions as proxies for predicting news controversy. We prove the validity of this approach by running within- and across-source exper- iments, where different news sources are conceived to approximately correspond to different reader communities. Contextu- ally, we also present and share an au- tomatically generated corpus for contro- versy prediction in Italian.
A branching heuristic based on variable decision levels

Efficient branching heuristic is a key feature of modern SAT solvers. Firstly, this paper introduced VSIDS heuristic and VSIDS-based heuristics like EVSIDS and ACIDS. Based on VSIDS, a new heuristic termed DLBH that considers variable decision levels was proposed to promote the efficiency of variable selection process. Then, instances showed the comparison among EVSIDS, ACIDS and DLBH. Finally, experimental results indicated that MiniSat solver with DLBH outperforms solvers MiniSat with VSIDS and Glucose.
Exercise therapy after corticosteroid injection for moderate to severe shoulder pain: large pragmatic randomised trial

Objective To compare the effectiveness of subacromial corticosteroid injection combined with timely exercise and manual therapy (injection plus exercise) or exercise and manual therapy alone (exercise only) in patients with subacromial impingement syndrome. Design Pragmatic randomised clinical trial. Setting Primary care based musculoskeletal service. Patients Adults aged 40 or over with subacromial impingement syndrome with moderate or severe shoulder pain. Interventions Injection plus exercise or exercise only. Main outcome measures Primary outcome was the difference in improvement in the total shoulder pain and disability index at 12 weeks. Results 232 participants were randomised (115 to injection plus exercise, 117 to exercise only). The mean age was 56 (range 40-78), 127 were women, and all had had a median of 16 weeks of shoulder pain (interquartile range 12-28). At week 12 there was no significant difference between the groups in change in total pain and disability index (mean difference between change in groups 3.26 (95% confidence interval −0.81 to 7.34), P=0.116). Improvement was significantly greater in the injection plus exercise group at week 1 (6.56, 4.30 to 8.82) and week 6 (7.37, 4.34 to 10.39) for the total pain and disability index (P<0.001), with no differences at week 24 (−2.26, −6.77 to 2.25, P=0.324). Conclusions In the treatment of patients with subacromial impingement syndrome, injection plus exercise and exercise only are similarly effective at 12 weeks.

Aggregation control in natural brush-printed conjugated polymer films and implications for enhancing charge transport

Significance Shear-printing of electroactive polymers using natural brushes is a promising film deposition technique for printed electronics capable of microstructure control and electrical properties enhancement over large areas. Nevertheless, the interplay between film printing parameters, microstructure development, and charge transport is not well-understood. We report that natural brush-printing greatly enhances charge transport by as much as 5.7× through control of polymer nanofibril aggregate growth and backbone alignment, attributable to the oriented squamae of the natural hair. However, while brush shear-induced aggregation enhances charge transport, we show that backbone alignment alone does not guarantee charge transport anisotropy. These results provide additional understanding of shear-induced enhanced charge transport and set processing guidelines for high-performance printed organic circuitry. Shear-printing is a promising processing technique in organic electronics for microstructure/charge transport modification and large-area film fabrication. Nevertheless, the mechanism by which shear-printing can enhance charge transport is not well-understood. In this study, a printing method using natural brushes is adopted as an informative tool to realize direct aggregation control of conjugated polymers and to investigate the interplay between printing parameters, macromolecule backbone alignment and aggregation, and charge transport anisotropy in a conjugated polymer series differing in architecture and electronic structure. This series includes (i) semicrystalline hole-transporting P3HT, (ii) semicrystalline electron-transporting N2200, (iii) low-crystallinity hole-transporting PBDTT-FTTE, and (iv) low-crystallinity conducting PEDOT:PSS. The (semi-)conducting films are characterized by a battery of morphology and microstructure analysis techniques and by charge transport measurements. We report that remarkably enhanced mobilities/conductivities, as high as 5.7×/3.9×, are achieved by controlled growth of nanofibril aggregates and by backbone alignment, with the adjusted R2 (R2adj) correlation between aggregation and charge transport as high as 95%. However, while shear-induced aggregation is important for enhancing charge transport, backbone alignment alone does not guarantee charge transport anisotropy. The correlations between efficient charge transport and aggregation are clearly shown, while mobility and degree of orientation are not always well-correlated. These observations provide insights into macroscopic charge transport mechanisms in conjugated polymers and suggest guidelines for optimization.
L'évolution des politiques sociales en Hongrie depuis la transformation du système

Au cours des deux dernieres decennies, il y a eu un changement de paradigme quant a l'orientation des politiques publiques. Ce changement a affaibli la legitimite du modele de l'Etat- providence a l'europeenne et a renforce celle d'un modele neo-liberal ou neo-conservateur. Ce glissement a affecte les valeurs et objectifs sociaux fondamentaux tout autant que les relations de pouvoir entre acteurs, ainsi que les institutions et instruments au service de la politique sociale. En Hongrie, comme dans d'autres pays en transition, l'attrait du nouveau paradigme est plus fort que dans les pays ouest- europeens. Les organismes internationaux (FMI, Banque Mondiale) et les nombreux groupes d'interet nationaux ont donc pu porter atteinte aux institutions de protection sociale. Resultat : les prestations universelles sont en grande partie supprimees, les prestations d'assurance sociale se sont deteriorees et partiellement privatisees, tandis que l'assistance sociale, c'est-a-dire les prestations ciblees et conditionnees aux ressources, a gagne du terrain. Malgre tout, l'accroissement des libertes a permis une certaine resistance civile et une attention accrue portee aux droits sociaux. Cependant, les reformes, fortement influencees par le modele americain, pourraient accroitre l'ecart entre les pays est- et ouest-europeens.
FAST KICKER

We analyze the possibilities for minimizing the kic ker rise time down to the rise time of the feeding pulse. For this we are sug gesting a 90 o orientation of the strip line kicker and the beam. As a pulser we are sugges tin a device using many vacuum tubes working in parallel. In particular, we are proposing a scheme able to provide a kick to 5 GeV bunch, removing it from its orbit in a ~10nsec time window. Establishing/dropping time for the system is estimated to be ~ 0.1 nsec with the ab ility for a repetition rate up to 3 MHz supported by the suggested pulser. However, relaxed conditions for ERL allow usage of traditional kicker system with counter propagation of beam and kicking pulse. 1. OVERVIEW Kicker is a device for delivering transverse (ty pically) momentum to the charged particle beam. Basically, the kicker acts through the electr omagnetic (EM) field generated by currents running in its electrodes. As a rule, fiel d in a kicker lasts for a rather short period of time, so it acts to the selected part of the bea m only (typically to a selected bunch in a sequence). So the pulsed power supply for this kick er plays an important role in all processes as well as configuration of electrodes an d co ductors in the kicker itself. So to speak, the kicker electrodes (conductors) and the s ource of short EM pulse for feeding these electrodes represent an integrated unity. By having the powerful source of short pulses in hand one can simplify the task for design ing such pulsed system able to act in a short time. Figure 1: Long kickers (top) and short ones (bottom ). All fast kickers described so far are strip-line el ctrodes fed by counter propagating EM pulse. As the length of such kicker could not be lo nger than the half of distance between bunches, the kicker typically sectioned by many uni ts having short length each, Fig. 1. There is no limit for the minimal length of kicker. For matching the impedance of strip line
Local experience of endorectal magnetic resonance imaging of prostate with correlation to radical prostatectomy specimens.

INTRODUCTION We evaluated the accuracy of endorectal magnetic resonance imaging (MRI) in the staging of prostate cancer. MATERIALS AND METHODS We retrospectively reviewed 32 patients who underwent endorectal MR prostate prior to radical prostatectomy. The tumour stage based on MR imaging was compared with the pathologic stage. The sensitivity and specificity of endorectal MR prostate in the evaluation of extracapsular extension (ECE) of the tumour were then determined. RESULTS MR correctly diagnosed 17 cases of organ-confined prostate carcinoma and 2 cases of locally advanced disease. In the evaluation of ECE, endorectal MR achieved a high specificity of 94.4%, low sensitivity of 14.3% and moderate accuracy of 59.4%. CONCLUSION Endorectal MR prostate has high specificity for the detection of ECE. It is useful in the local staging of prostate cancer in patients with intermediate risk as this helps to ensure that few patients will be deprived of potentially curative surgery.
A new method for color image segmentation based on FSVM

Image segmentation is very essential and critical to image processing and pattern recognition. It is known that, color image segmentation approaches are based on monochrome segmentation approaches operating in different color spaces. So in this paper, an improved method which uses the FSVM (fuzzy support vector machines) algorithm for color image segmentation in the HSI (hue-saturation-intensity) color space was proposed. Experiments show that the proposed algorithm has better effect and lower computational complexity on color image segmentation than other method.

Laboratório de Bacterioses dos Animais Domésticos, Departamento de Medicina Veterinária, Universidade Federal Rural de Pernambuco, Av. Dom Manoel de Medeiros s/n, Recife, PE 52171-900, Brazil. E-mail: sanbsantos@gmail.com The aim of the present study was to report the occurrence of members of the Mollicutes class in the reproductive system of dairy cattle in Brazil. Five farms containing dairy cattle were visited in January of 2012. In total, 100 cows of different ages, breeds and stages of lactation were examined in the present study. The cows were part of intensive or semi-intensive management systems and were submitted to mechanical milking or hand milking. The samples were collected after washing the vulvar region with water and soap, and then drying it with paper towels and disinfecting the area with alcohol (70°GL). Vaginal mucous was collected using a sterile alginate cotton swab, which was rubbed on the vagina, as well as the lateral and internal walls. Vulvovaginal mucous samples were cultured in both liquid and solid modified Hayflick ́s medium, for mycoplasmas, and UB medium, for ureaplasmas. The PCR assays for Mollicutes and Ureaplasma spp. were performed according to the standard protocols described in the current literature. During isolation, the frequency of Mycoplasma spp. was of 13.0% (13/100) and for Ureaplasma spp. was of 6.0% (6/100). In the PCR assays the frequency of Mollicutes was of 26.0% (26/100) and for Ureaplasma spp. was of 13.0% (13/100) in the dairy cattle studied. This is the first report of these agents in reproductive system of bovine of the Pernambuco state. Further studies are necessary to determine the pathogenic potential and species of these field isolates.
