Published: August 2019

Abstract
The variation and uncertainty existed in every process and considered as an essential element in precise, accurate and high-quality manufacturing, especially in the Industry 4.0 era. Manufacturing quality and reliability is affected by variations and uncertainties in different process parameters and influencing factors. The variations and uncertainties are considered very critical in measurement and monitoring process, i.e., prediction or prognostics. These variations and subsequent uncertainties are needed to be identified, quantified, analyzed and controlled. This paper presents an approach to uncertainty measurement and analysis in manufacturing. The key characteristic parameter is identified which is critical for final product quality and reliability. To determine the uncertainty in the specific parameter, the uncertainty factors of both the manufacturing process and measurement process are determined. The combined uncertainty is determined by considering the influencing factors both in manufacturing and measurement process. The relation of each factor to the key parameter is analyzed and the sensitivity coefficient is determined mathematically or experimentally. The combined and expanded uncertainty is determined considering all related factors. The proposed approach has been applied to an additive manufacturing technique, and useful results are achieved.

Abstract
Aiming at the difficulties in accurate prediction of the dressing amount of monolayer electroplated grinding wheel, a new calculation method based on image processing was proposed. For the purpose of increasing the measurement precision, all images were captured by CCD camera and a sub-pixel level accuracy edge detection approach based on Zernike moment was used. Two dressing amount of electroplated grinding wheel were calculated by protrusion height and run-out respectively, and the larger number of them was chosen as the optimal dressing amount. Finally, this method is applied to calculate the optimal dressing amount of 30 gothic-arc profile electroplated grinding wheels, and they were dressed by optical contour grinder. The results showed that, form precision of grinding wheels and roughness of workpiece were fine.

Authors: Xu Wen-Xue , Lü Zhen-Hua , Zhou Ping-Zhang 
Published: August 2019

Abstract
The structure, fluid and gas dynamic models of a gas-pressured hydraulic shock absorber are established to form a 3-D FSI (Fluid-Structure Interaction) simulation model, which can be used to predict the working characteristics and kinematical responses of the valve plates, as well as the flow characteristics, transient fluid pressure and velocity distribution of the shock absorbers. The working characteristics obtained from the simulation model are compared with the experimental results to prove the effectiveness of the simulation model. It is shown that the dynamic characteristics of the shock absorber can be predicted quite accurately by the 3-D FSI simulation model, which is meaningful to the understanding of the inner working mechanism of the shock absorber system.

Association of Sleep Duration and Blood Pressure in Adolescents: A Multicenter Study
Authors: Dos Santos Emanuela De Souza Gomes , De Souza Orivaldo Florencio 
Published: August 2019

Abstract

BACKGROUND
Evidence suggests that sleep duration is related to blood pressure (BP), but the findings are still inconsistent for adolescents.

OBJECTIVE
To analyze the association between sleep duration and BP in Brazilian adolescents between 12 and 17 years of age.

METHODS
This study is part of the Study of Cardiovascular Risk in Adolescents (ERICA), a multicenter, school-based, cross-sectional study in 273 municipalities in Brazil. The sample consisted of 65,643 adolescents. Sleep duration was measured by a subjective method, and BP was measured by the oscillometric method. Multiple linear regression analyses were performed to evaluate the association between sleep duration and BP.

RESULTS
The mean sleep duration was 8.14 hours (± 1.40), with significant difference between the groups according to BP levels (P &lt; 0.0001). The mean systolic and diastolic BP were 110.59 (± 11.87) and 65.85 (± 7.94) mm Hg, respectively, in the group of adolescents. Sleep duration was significantly associated with BP. Each increase 1 hour in sleep was associated with BP reduction in both sexes combined (P &lt; 0.0001). Considering the effects of covariates, each increase 1 hour in sleep was associated with systolic BP (SBP) reduction among boys (P = 0.004) and SBP elevation among girls (P = 0.009), after full adjustment.

CONCLUSION
The results suggest that each increase in sleep duration was associated with SBP elevation among girls. Such findings may have important implications for cardiovascular health in adolescence.
Fast exact conformalization of the lasso using piecewise linear homotopy
Authors: Lei J 
Published: August 2019

SummaryConformal prediction is a general method that converts almost any point predictor to a prediction set. The resulting set retains the good statistical properties of the original estimator under standard assumptions, and guarantees valid average coverage even when the model is mis-specified. A main challenge in applying conformal prediction in modern applications is efficient computation, as it generally requires an exhaustive search over the entire output space. In this paper we develop an exact and computationally efficient conformalization of the lasso and elastic net. The method makes use of a novel piecewise linear homotopy of the lasso solution under perturbation of a single input sample point. As a by-product, we provide a simpler and better-justified online lasso algorithm, which may be of independent interest. Our derivation also reveals an interesting accuracy-stability trade-off in conformal inference, which is analogous to the bias-variance trade-off in traditional parameter estimation. The practical performance of the new algorithm is demonstrated in both synthetic and real data examples.
Zebrafish studies identify serotonin receptors mediating antiepileptic activity in Dravet syndrome

Published: August 2019

Abstract
Dravet syndrome is a life-threatening early-onset epilepsy not well controlled by antiepileptic drugs. Drugs that modulate serotonin (5-HT) signalling, including clemizole, locaserin, trazodone and fenfluramine, have recently emerged as potential treatment options for Dravet syndrome. To investigate the serotonin receptors that could moderate this antiepileptic activity, we designed and synthesized 28 novel analogues of clemizole, obtained receptor binding affinity profiles, and performed in vivo screening in a scn1lab mutant zebrafish (Danio rerio) model which recapitulates critical clinical features of Dravet syndrome. We discovered three clemizole analogues with 5-HT receptor binding that exert powerful antiepileptic activity. Based on structure–activity relationships and medicinal chemistry-based analysis, we then screened an additional set of known 5-HT receptor specific drug candidates. Integrating our in vitro and in vivo data implicates 5-HT2B receptors as a critical mediator in the mechanism of seizure suppression observed in Dravet syndrome patients treated with 5-HT modulating drugs.
Distance and proximity in Hubert Robert
Authors: Jones Nathaniel B , Ryu Sara 
Published: August 2019

AbstractThis essay focuses on questions of distance and proximity, both chronological and spatial, in the painting of eighteenth-century French artist Hubert Robert. It argues that, through the manipulation of different modes of distance in his paintings, Robert sought to articulate an aesthetic attitude which highlighted the remoteness of the past at the same time as he brought it into dialogue with the present. This aesthetic of distance is variously enacted by Robert's pictorial reflections on the ancient Roman system of roads, the virtual creation and collection of antiquities, and the actual movement of the physical remnants of the ancient world. The result, the essay suggests, is that Robert's work straddles the border of fiction and reference to both acknowledge and deny the presentness of the past.
Mobilizing Pompeii for Italian Silent Cinema
Authors: Wyke Maria 
Published: August 2019

Abstract
A documentary film about the eruption of Vesuvius in 1906 juxtaposes scenes of the damage and deaths it caused in neighbouring communities with shots of Pompeii — the ancient city of the long-since dead. The documentary suggests that Pompeii is a picturesque site where the privileged tourist experiences aesthetic detachment from the excavators’ labour or the locals’ suffering. Despite this critique, four Italian fiction films about the last days of Pompeii were made between 1908 and 1926. This article explores those films and argues that they mobilize Pompeii both for modern Italians and for cinema. They situate viewers immersively within the reconstructed city and substitute for a detached tourist gaze an impassioned, participatory one.

SummaryBackgroundPain can discourage patients from seeking orthodontic treatment or compromise their compliance during therapy.ObjectivesTo determine the effects of verbal and written information on orthodontic pain after fixed appliance placement.Trial designTwo-arm parallel design randomized controlled trial.MethodsHealthy adolescents with permanent dentition enrolled for orthodontic treatment were assigned to the study or control group using computer-generated random lists and allocation concealment with sealed envelopes. Participants completed baseline questionnaires to assess anxiety (State-Trait Anxiety Inventory Trait Version, Form X-2) and somatosensory amplification (Somatosensory Amplification Scale). Brackets were placed in the maxillary arch, from first molar to first molar, and an Australian archwire 0.012 inch was used for alignment. General verbal information on orthodontic treatment was given to all patients by the same clinician. Participants included in the study group received also detailed verbal instructions on orthodontic pain together with a take-home information leaflet by another clinician. Outcome included assessments of pain intensity with a Numerical Rating Scale (NRS) on the day of appliance placement (Day 1, bedtime) and twice a day for the following 6 days (Day 2 to Day 7, morning, bedtime), and analgesic consumption. Participants, statistician, and clinicians who gave general verbal information on orthodontic treatment and instructions about how to score pain intensity were blinded to group assignment.ResultsSixty patients were assigned to the study (n = 30, mean age: 15.4 ± 1.3 years) or control group (n = 30, mean age: 14.7 ± 3.2 years). At baseline, no significant between-group differences were present in terms of anxiety and somatosensory amplification. Orthodontic pain scores were significantly lower in the study group compared with the control one, at bedtime on Day 1 (P &lt; 0.05) and in the morning of Day 2 (P &lt; 0.01). No significant between-group differences were found in following measurements. Overall, analgesic consumption was significantly lower in study compared with the control (P &lt; 0.01).ConclusionA combination of verbal and written information on orthodontic pain after placement of fixed appliances reduced patient’s self-reported pain in the early stages.RegistrationThis study was not registered.

Abstract

Aims
The DANish Acute Myocardial Infarction 2 (DANAMI-2) trial found that interhospital transport to primary percutaneous coronary intervention (pPCI) was superior to fibrinolysis at the local hospital in patients with ST-segment elevation myocardial infarction (STEMI) at 30 days. The present study investigates the 16-year cardiovascular outcomes.

Methods and results
We randomized 1572 STEMI patients to pPCI or fibrinolysis at 24 referral hospitals and 5 invasive centres in Denmark. Patients randomized to pPCI at referral hospitals were immediately transported to the nearest invasive centre. The main endpoint of the current study was a composite of death or rehospitalization for myocardial infarction (MI). Outcome information beyond 3 years was obtained through Danish health registries. After 16 years, pPCI-treated patients had a sustained lower rate of composite endpoint compared to patients treated with fibrinolysis in the overall cohort [58.7% vs. 62.3%; hazard ratio (HR) 0.86, 95% confidence interval (CI) 0.76–0.98], and among patients transported for pPCI (58.7% vs. 64.1%; HR 0.82, 95% CI 0.71–0.96). No difference in all-cause mortality was found, but cardiac mortality was reduced by an absolute of 4.4% in favour of pPCI (18.3% vs. 22.7%; HR 0.78, 95% CI 0.63–0.98). pPCI postponed a main event with 12.3 months in average compared to fibrinolysis (95% CI 5.0–19.5).

Conclusion
The benefit of pPCI over fibrinolysis was maintained at 16-year follow-up. pPCI reduced the composite endpoint of death or rehospitalization for MI, reduced cardiac mortality, and delayed average time to a main event by approximately 1 year.
