Published: November 2020

Abstract
Steel skeleton supported membrane structure is the major structural form of membrane structure, accounting for more than 50%. The structural characteristics of membrane structure itself determine that the analysis of its self-vibration characteristics is very important in the design process. According to the von Karman’s large deflection theory and the D’Alembert’s principle, the governing equations of nonlinear viscous damping vibration of the skeleton supported orthotropic membrane structure were proposed. By applying the Galerkin method and the KBM perturbation means of obtaining the analytical solutions of frequency function, displacement function and mode function of damped nonlinear and linear free vibration of simply supported orthotropic membrane structures on four sides were obtained. In addition, it can be known by example analysis that the transverse stiffness of membrane structure can be improved by increasing prestress and rise span ratio in the practical engineering, and while the influence of geometrically nonlinear, orthotropic, damping and prestress on the dynamic feature of membrane structure must be fully considered. This paper provides some theoretical references for the wind-induced dynamic stability calculation and wind-resistant design of the steel skeleton supported membrane structure.

Abstract
The infiltration casting method is used for the preparation of three-dimensional co-continuous network structure of graphite/cast steel composite material in atmospheric pressure. Using modal analysis method, flake graphite cast iron specimen and composite sample are compared about damping factors. The results show that amplitude attenuation of the composite material is more quickly than that of flake graphite cast iron specimens. Supported in two rigid points state, the first step damping ratio of the composite material is 2.1 times of flake graphite cast iron. At the same time, its tensile strength is 1.54 to 1.68 times that of flake graphite cast iron, its hardness reaches more than 86%, and its bulk density is reduced to less than 94%. The composite not only has good vibration damping and anti-friction performance, but also has comprehensive mechanical properties exceeding the level of flake graphite cast iron. It is possible to replace flake graphite cast iron for manufacturing important mechanical equipment castings such as fuselage and guide rail to obtain better anti-wear / vibration damping effect.

Authors: Lu Xiaoling , Chen Changlang 
Published: November 2020

Abstract
In-mould transfer printings are limited, such as surface bending, only on plastic parts, cost higher and print for a small run length of productions. OMR transfer can be transferred to plastic or metal, transfer process accurate register, high quality and tolerance. The current printing market tend to develop personalized, so this study to use digital inkjet printing, through rigorous experimental process and quantitative measurement and comprehensive analysis, summarized the most suitable digital inkjet printing methods and the best quality attributes. In each combination, the samples will be selected to transfer printed products which will be examined for print quality attributes (SID, TVI, PC, colour difference and colour gamut). This study results found that when the higher coverage and the lower pass of inkjet printing, the SIDs will become higher as well. When transferred to ABS, SIDs in each combination will increase. The higher coverage printed, the higher TVI. After transferred into ABS, each combination of PC is worst. When transferred to ABS, colour variances of each combination are different from orange and cyan colour. Through this study, we can get the colour correspondence between the original and the finished product ABS, to establish the personalized service process, to improve the digital inkjet printing and technology application to enhance its product added value, and to provide research results to give back to the printing market. It can bring new opportunities for the industry.

Authors: Ma Jianqin , Xue Chen , Wang Le , Fang Pan , Ren Ke 
Published: November 2020

Abstract
Cast-in-place concrete lining, which is the major structure of a tunnel with composite or monolithic lining, requires high safety, durability and waterproof performance. The prevention and control of lining concrete cracks are of great concern. However, the temperature and shrinkage cracks in the arch and wall of a cast-in-place concrete lining are common construction quality defects in practical cases. This contribution presents the changing features of temperature crack widths in responding to the temperature variation with seasons in several cast-in-place final ling panels, where there are no waterproof and drainage sheets in their composite linings. The crack width changing features imply that the constraints to the temperature drop and shrinkage deformation of the concrete in its arch and wall in construction stage still work in the period of post-construction. Considering the cracks beyond the planned allowable values, the information on the width changing features presents clue to determine the rule on the occurring and developing of the temperature and shrinkage cracks in the cast-in-place lining concrete, as well as crack resistance design and construction quality control.

Authors: Narita Keisuke , Hoshide Satoshi , Kanegae Hiroshi , Kario Kazuomi 
Published: November 2020

Abstract

BACKGROUND
Little is known about seasonal variation in nighttime blood pressure (BP) measured by a home device. In this cross-sectional study, we sought to assess seasonal variation in nighttime home BP using data from the nationwide, practice-based Japan Morning Surge-Home BP (J-HOP) Nocturnal BP study.

METHODS
In this study, 2,544 outpatients (mean age 63 years; hypertensives 92%) with cardiovascular risks underwent morning, evening, and nighttime home BP measurements (measured at 2:00, 3:00, and 4:00 am) using validated, automatic, and oscillometric home BP devices.

RESULTS
Our analysis showed that nighttime home systolic BP (SBP) was higher in summer than in other seasons (summer, 123.3 ± 14.6 mmHg vs. spring, 120.7 ± 14.8 mmHg; autumn, 121.1 ± 14.8 mmHg; winter, 119.3 ± 14.0 mmHg; all P&lt;0.05). Moreover, we assessed seasonal variation in the prevalence of elevated nighttime home SBP (≥120 mmHg) in patients with non-elevated daytime home SBP (average of morning and evening home SBP &lt;135 mmHg; n = 1,565), i.e., masked nocturnal hypertension, which was highest in summer (summer, 45.6% vs. spring, 27.2%; autumn, 28.8%; winter, 24.9%; all P&lt;0.05). Even in intensively controlled morning home SBP (&lt;125 mmHg), the prevalence of masked nocturnal hypertension was higher in summer (summer, 27.4% vs. spring, 14.2%; autumn, 8.9%; winter, 9.0%; all P&lt;0.05). The urine albumin–creatinine ratio in patients with masked nocturnal hypertension tended to be higher than that in patients with non-elevated both daytime and nighttime SBP throughout each season.

CONCLUSIONS
The prevalence of masked nocturnal hypertension was higher in summer than other seasons and the difference proved to be clinically meaningful.
Systemic targeted and immunotherapy for advanced hepatocellular carcinoma
Authors: Cersosimo Robert J 
Published: November 2020

AbstractPurposeThe activity of targeted agents and immunotherapy in the management of advanced hepatocellular carcinoma (HCC) is reviewed.SummaryThe first drug approved by the Food and Drug Administration for advanced HCC, sorafenib, was approved in 2007. Regorafenib, the second drug, was approved 10 years later. Six additional drugs have been approved since. Targeted agents and checkpoint inhibitors are the only agents approved for systemic therapy of advanced HCC. Sorafenib and lenvatinib are approved as first-line agents, with regorafenib, cabozantinib, ramucirumab, nivolumab (used alone or with ipilimumab), and pembrolizumab approved for patients who have received prior sorafenib therapy. Most patients in phase 3 studies had Child-Pugh class A cirrhosis, and data on the use of these agents in patients with more advanced hepatic dysfunction are limited. All of the targeted agents improve survival in patients with advanced disease. Median overall survival durations of up to 12.3 and 13.6 months were reported with use of sorafenib and lenvatinib, respectively, in phase 3 trials. Overall survival durations of 10.6, 10.2, and 9.2 months have been achieved with use of regorafenib, cabozantinib, and ramucirumab as second-line therapy after sorafenib. A median overall survival of 13.2 months was reported in 1 cohort of a dose-expansion study of nivolumab in which all patients received prior sorafenib therapy. Median survival durations of 12.9 months and 13.9 months were reported with use of pembrolizumab in patients with a history of sorafenib therapy. The most common adverse effects associated with targeted agents are dermatological effects, diarrhea, fatigue, and hypertension. Immune-mediated adverse effects are associated with checkpoint inhibitors.ConclusionTargeted agents and checkpoint inhibitors are the standard of therapy for patients who need systemic therapy for advanced HCC.
Facelift Surgery Turns Back the Clock: Artificial Intelligence and Patient Satisfaction Quantitate Value of Procedure Type and Specific Techniques
Authors: Gibstein Alexander R , Chen Kevin , Nakfoor Bruce , Lu Stephen M , Cheng Roger , Thorne Charles H , Bradley James P 
Published: November 2020

Abstract

Background
Patients desire facelifting procedures to look younger, refreshed, and attractive. Unfortunately, there are few objective studies assessing the success of types of facelift procedures and ancillary techniques.

Objectives
The authors sought to utilize convolutional neural network algorithms alongside patient-reported FACE-Q outcomes to evaluate perceived age reduction and patient satisfaction following various facelift techniques.

Methods
Standardized preoperative and postoperative (1-year) images of patients who underwent facelift procedures were analyzed by 4 neural networks to estimate age reduction after surgery (n = 105). FACE-Q surveys were employed to measure patient-reported facial aesthetic outcome. We compared (1) facelift procedure type: skin-only vs superficial musculoaponeurotic system (SMAS)-plication, vs SMAS-ectomy; and (2) ancillary techniques: fat grafting (malar) vs no fat grafting. Outcomes were based on complications, estimated age-reduction, and patient satisfaction.

Results
The neural network preoperative age accuracy score demonstrated that all neural networks were accurate in identifying our patients’ ages (mean score = 100.4). SMAS-ectomy and SMAS-plication had significantly greater age-reduction (5.85 and 5.35 years, respectively) compared with skin-only (2.95 years, P &lt; 0.05). Fat grafting compared to no fat grafting demonstrated 2.1 more years of age reduction. Facelift procedure type did not affect FACE-Q scores; however, patients who underwent fat grafting had a higher satisfaction with outcome (78.1 ± 8 vs 69 ± 6, P &lt; 0.05) and decision to have the procedure (83.0 ± 6 vs 72 ± 9, P &lt; 0.05).

Conclusions
Artificial intelligence algorithms can reliably estimate the reduction in apparent age after facelift surgery. Facelift technique, like SMAS-ectomy or SMAS-plication, and specific technique, like fat grafting, were found to enhance facelifting outcomes and patient satisfaction.

Authors: Lin Michael F , Bai Xiaodong , Salerno William J , Reid Jeffrey G 
Published: November 2020

Abstract

Summary
Variant Call Format (VCF), the prevailing representation for germline genotypes in population sequencing, suffers rapid size growth as larger cohorts are sequenced and more rare variants are discovered. We present Sparse Project VCF (spVCF), an evolution of VCF with judicious entropy reduction and run-length encoding, delivering &gt;10× size reduction for modern studies with practically minimal information loss. spVCF interoperates with VCF efficiently, including tabix-based random access. We demonstrate its effectiveness with the DiscovEHR and UK Biobank whole-exome sequencing cohorts.

Prioritizing genes for systematic variant effect mapping
Authors: Kuang Da , Truty Rebecca , Weile Jochen , Johnson Britt , Nykamp Keith , Araya Carlos , Nussbaum Robert L , Roth Frederick P 
Published: November 2020

Abstract

Motivation
When rare missense variants are clinically interpreted as to their pathogenicity, most are classified as variants of uncertain significance (VUS). Although functional assays can provide strong evidence for variant classification, such results are generally unavailable. Multiplexed assays of variant effect can generate experimental ‘variant effect maps’ that score nearly all possible missense variants in selected protein targets for their impact on protein function. However, these efforts have not always prioritized proteins for which variant effect maps would have the greatest impact on clinical variant interpretation.

Results
Here, we mined databases of clinically interpreted variants and applied three strategies, each building on the previous, to prioritize genes for systematic functional testing of missense variation. The strategies ranked genes (i) by the number of unique missense VUS that had been reported to ClinVar; (ii) by movability- and reappearance-weighted impact scores, to give extra weight to reappearing, movable VUS and (iii) by difficulty-adjusted impact scores, to account for the more resource-intensive nature of generating variant effect maps for longer genes. Our results could be used to guide systematic functional testing of missense variation toward greater impact on clinical variant interpretation.

Altered sense of agency in Gilles de la Tourette syndrome: behavioural, clinical and functional magnetic resonance imaging findings
Authors: Zapparoli Laura , Seghezzi Silvia , Devoto Francantonio , Mariano Marika , Banfi Giuseppe , Porta Mauro , Paulesu Eraldo 
Published: November 2020

Abstract
Current neurocognitive models of motor control postulate that accurate action monitoring is crucial for a normal experience of agency—the ability to attribute the authorship of our actions and their consequences to ourselves. Recent studies demonstrated that action monitoring is impaired in Gilles de la Tourette syndrome, a movement disorder characterized by motor and vocal tics. It follows that Tourette syndrome patients may suffer from a perturbed sense of agency, the hypothesis tested in this study. To this end, we recruited 25 Tourette syndrome patients and 25 matched healthy controls in a case-control behavioural and functional magnetic resonance imaging study. As an implicit index of the sense of agency, we measured the intentional binding phenomenon, i.e., the perceived temporal compression between voluntary movements and their external consequences. We found evidence of an impaired sense of agency in Tourette syndrome patients who, as a group, did not show a significant intentional binding. The more reduced was the individual intentional binding, the more severe were the motor symptoms. Specific differences between the two groups were also observed in terms of brain activation patterns. In the healthy controls group, the magnitude of the intentional binding was associated with the activity of a premotor–parietal–cerebellar network. This relationship was not present in the Tourette syndrome group, suggesting an altered activation of the agency brain network for self-generated acts. We conclude that the less accurate action monitoring described in Tourette syndrome also involves the assessment of the consequences of actions in the outside world. We discuss that this may lead to difficulties in distinguishing external consequences produced by their own actions from the ones caused by others in Tourette syndrome patients.
Hybrid Multi-Channel EEG Filtering Method for Ocular and Muscular Artifact Removal Based on the 3D Spline Interpolation Technique

Published: November 2020

Abstract
The present work develops a novel hybrid method for ocular and muscular artifact removal from electroencephalography (EEG) signals, EFICA-TQWT. It is a combination of efficient fast independent component analysis (EFICA) method with the tunable Q-factor wavelet transform (TQWT). The main contribution of this paper is to apply the 3D interpolation method in the filtering system. Three EEG datasets are used in this work, two healthy and one epileptic. The choice of subjects for each dataset is made with the help of an expert in physiology. The selection criterion adopted is the presence of muscular and ocular artifacts in the processed recordings. First, a noisy channel automatic classification is performed by the support vector machine (SVM) with radial basis function in order to delete the signal(s) corresponding to the noisiest channel(s) from each EEG recording. The results of the automatic classification by the SVM were compared with those found by the expert’s classification. An accuracy of 97.45%, a sensitivity of 86.66% and a 100% specificity are provided by the SVM classification. The hybrid method of artifact removal will be applied on the rest of the EEG channels of international 10/20 system for each subject. Then, a reconstruction of the eliminated channel signal(s) will be performed in order to obtain a well-filtered signal. The proposed filtering process is evaluated by calculating the mean squared error (MSE) and the signal to noise ratio (SNR). Both for the healthy and pathological EEG datasets, a comparative study of the proposed method (EFICA-TQWT) and other filtering techniques (Fast-ICA, DWT, TQWT and EFICA) is generated. The EFICA-TQWT method gave the best results with a minimum of MSE and a maximum of SNR, more particularly in the case of the application of the 3D interpolation method. Besides, in order to optimize the computing time of the proposed system, a parallel implementation of this filtering system is developed based on graphical processing units using compute unified device architecture.

Abstract

Objectives
Near-infrared (NIR) spectroscopy is a rapid technique able to assess meat quality even if its capability to determine the shelf life of chicken fresh cuts is still debated, especially for portable devices. The aim of the study was to compare bench-top and portable NIR instruments in discriminating between four chicken breast refrigeration times (RT), coupled with multivariate classifier models.

Materials and Methods
Ninety-six samples were analysed by both NIR tools at 2, 6, 10 and 14 days post mortem. NIR data were subsequently submitted to partial least squares discriminant analysis (PLS-DA) and canonical discriminant analysis (CDA). The latter was preceded by double feature selection based on Boruta and Stepwise procedures.

Results
PLS-DA sorted moderate separation of RT theses, while shelf life assessment was more accurate on application of Stepwise-CDA. Bench-top tool had better performance than portable one, probably because it captured more informative spectral data as shown by the variable importance in projection (VIP) and restricted pool of Stepwise-CDA predictive scores (SPS).

Conclusions
NIR tools coupled with a multivariate model provide deep insight into the physicochemical processes occurring during storage. Spectroscopy showed reliable effectiveness to recognise a 7-day shelf life threshold of breasts, suitable for routine at-line application for screening of meat quality.
