Abstract:
AbstractNortheast China (NEC) has sustained economic losses in recent years because of extreme precipitation events. Despite many efforts, it remains very difficult to predict these extreme events. In this study, we documented the characteristics of extreme precipitation days (EPD) over NEC and established a seasonal prediction model using a year-to-year increment (DY) approach. The results show that most of the EPD over NEC occurred during midsummer, along with large values concentrated over the Greater and Lesser Khingan Mountains and Changbai Mountain. Two variables—the preceding early spring soil moisture DY over central Asia and the sea surface temperature DY in the tropical Atlantic Ocean—were used to construct the statistical model to predict the EPD DY over NEC. These two factors influenced the EPD by modulating the moisture transport over NEC. Cross-validation tests for the period from 1962 to 2016 and independent hindcasts for the period from 1997 to 2016 indicated that the two variables gave good predictions of the EPD over NEC. The observed and predicted year-to-year increments in EPD were well correlated, with a correlation coefficient of 0.65 for the period from 1962 to 2016 in the cross-validation test. In addition, the EPD DY covaried coherently with the midsummer precipitation amount DY over NEC, and those two predictors also gave good predictions for the midsummer precipitation amount over NEC. The correlation coefficient is 0.68 between the observed and predicted year-to-year increment in the amount of midsummer precipitation from 1962 to 2016 in a cross-validation test.

Abstract:
This paper concerned with modeling of the strain rate dependent material behavior of 3D-textile composites with simultaneous consideration of production and operational (e.g. pores or fatigue damage) defects. Therefore an additive model in the sense of continuum damage mechanics was introduced. For the model validation extensive experimental tests on glass non-crimp fabrics reinforced epoxy (GF-NCF/EP) composites are performed. The focus is put on the influence of production and fatigue related pre-damage under subsequent highly-dynamic tensile loading. The theoretical studies shows a good coincidence with the experimentally results

Abstract:
320 Background: Cisplatin based NAC prior to cystectomy is standard of care for MIBC, with 40-50% expected to respond with ≤pT1N0M0. Biomarkers predictive of response are lacking. Methods: MIBC pts who received 3 cycles of cisplatin based NAC on 1 of 2 prospective multicenter clinical trials were included. Pts treated with accelerated methotrexate, vinblastine, doxorubicin + cisplatin (AMVAC) provided the discovery set [n=34, 15/34 (44%) ≤pT1N0M0]. Pts treated with dose dense gemcitabine + cisplatin (DDGC) provided the validation set [n=24, 11/24 (46%) ≤pT1N0M0]. DNA from pre-treatment tumor tissue underwent sequencing for all coding exons of 287 cancer related genes and was analyzed for presence of base substitutions, indels, copy number alterations, and selected re-arrangements. The mean number of variants and variant status for each gene were correlated with response using two-sample t-test and Fisher’s exact tests. Variant data were used to create a classification tree to discriminate responders vs. non-responders in the AMVAC discovery cohort. The resulting decision rule was then tested in the independent DDGC validation set. Overall survival analysis was performed using Kaplan-Meier. Results: Pts with pT0 had significantly more alterations than those with residual tumor in both the AMVAC discovery (p=.024) and DDGC validation (p=0.018) set. In the AMVAC discovery set, alteration in ≥1 of the three DNA repair genes ATM, RB1 or FANCC predicted for ≤pT1N0M0 (p<0.001, 87% sensitivity, 100% specificity) and improved overall survival (OS) (p=0.007). This test remained predictive for ≤pT1N0M0 in the DDGC validation set (p=0.033), with a trend towards improved OS (p=0.07) at short median follow up of 14.3 mo. Conclusions: Alterations in ≥1 of ATM, RB1 and FANCC predict response to cisplatin based chemotherapy defined as ≤pT1N0M0 in both our AMVAC discovery and DDGC validation sets. We hypothesize that defects in these genes, which are important for maintenance of chromatin structure and DNA repair, confer sensitivity to DNA damaging chemotherapy and explain the accumulation of alterations seen among pts with pT0. External validation in collaboration with the cooperative groups is planned.

Abstract:
e13125 Background: The primary therapeutic objectives for advanced breast cancer (ABC) are to extend patients’ survival time and to maintain their quality of life (QoL). Patient-reported outcomes (PROs) symptom could improve communication with physicians, and decreased utilization of unplanned healthcare. However, localized PROs scales for ABC were seldomly used in China. This study aimed to develop a specific PROs scale for ABC patients in China and optimize the management model for breast cancer. Methods: A literature search was conducted in PubMed, Embase, Wanfang, and CNKI databases, and the dimensions and items of the scale in the literature were extracted for the item pool. Delphi method was used to modify, add, subtract, and adjust the language of scale items until the experts' suggestions or opinions reached a consensus, and the first draft of the scale was formed. The first draft of the scale was further optimized by cognitive test and pre-survey. The optimized scale was used for formal survey, and the items of the scale were further analyzed and screened by coefficient of variation, correlation coefficient, internal item consistency, factor analysis, reliability, and validity. All tests were two-sided tests, and the test level was α=0.05. Results: A total of 10945 articles were analyzed, and 237 were finally included to form an item pool containing 277 PRO items. Two rounds of Delphi expert consultation were conducted, and the average authority coefficient of experts was Cr>0.7. Based on the results of cognitive test, the corresponding items were revised by language description to facilitate understanding. After adjustments according to the pre-survey of 200 ABC patients, the PROs scale NCC-BC-A was finally formulated with a total of 38 items, including 9 physiological dimension items, 4 psychological dimension items, 9 social dimension items, 11 treatment-evaluation items, 4 overall self-evaluation dimension items, and 1 other dimension. A total of 588 ABC patients participated in the national formal survey of NCC-BC-A with the average answer time of 6 minutes, and no floor or ceiling effects were observed. A series of statistical tests were conducted on the result. A principal component analysis revealed that the items in PROs scale have great consistency while preserving enough differences between different dimensions. The results were tested to be normally distributed with good variation. Also, the PROs scale survey result has an excellent Cronbach's α coefficient of 0.925 and an excellent test-retest reliability of 0.9041. Conclusions: The PROs scale NCC-BC-A has high validity and reliability, can objectively measure the QoL of ABC patients. NCC-BC-A fully considered the characteristics of treatment status for ABC patients, and the realistic situation in China, which may help clinicians to pay more attention to QoL of ABC patients and to optimize management system for ABC.

Abstract:
Purpose – With a previous throughput of sea fish contamination with microorganisms, the present study extended the array of such spoilage over four other fish samples including Pseudapocryptes elongates, Scomberomorus cavalla, Xenentodon cancila and Otolithoides pama, evaluated the reductive impact of irradiation, and further validated the irradiation methodology in controlling the microbial quality of the sea fish samples. The paper aims to discuss these issues. Design/methodology/approach – Twelve samples of each sea fish were collected from super shops in Dhaka city and a portion of each sample was subjected to γ-irradiation at a dose of 3 kilo gray (kGy). Then, both non-irradiated and irradiated samples were tested for the presence of pathogenic bacteria though culture on different specific media followed by biochemical identification. Drug resistance among the pathogens was also investigated. Findings – Most of the non-irradiated samples were observed to harbor huge bacteria and fungi (1.3×102-1.5×107 cfu/g or cfu/ml) including the fecal coliforms ranging up to 105 cfu/g or cfu/ml, leading to an elevated threat to public health. Besides, the isolates were found to be resistant against single or multiple antibiotics, which further brought treatment complications during the possible disease outbreaks. However, the pathogenic load was significantly reduced after applying 3 kGy dose of γ-irradiation on the samples in consistent to the previous work using different fish samples. Research limitations/implications – A similar type of work has already been published by the group using different samples this year in the Journal of Microbiology, Biotechnology and Food Sciences, Vol. 2 No. 4, pp. 2420-2430. However, even being an increment of the previous work, the present work deals with extended array of sea fish samples with an objective of controlling food safety. Practical implications – The present work further confirms and assists the knowledge of food protection and the identification of spoiling bacteria and fungi by applying replicable methods projects of the novelty and practical outcome of the work. Originality/value – The reduction of pathogenic load revealed the efficacy of γ-irradiation as a mean of preserving fish quality. Besides, the study quantified the contaminating microorganisms as well as identified the drug-resistant bacteria among sea fish samples. Traditional but standard cultural and biochemical tests, demonstration of drug resistance among the isolated microorganisms from fish samples and finally the microbial elimination by irradiation might contribute to the existing knowledge on major sea fish.

Abstract:
Background. Distinguishing between benign and malignant peripheral nerve sheath tumors (MPNSTs) in neurofibromatosis 1 (NF1) patients prior to excision can be challenging. How can MPNST be most accurately diagnosed using clinical symptoms, magnetic resonance imaging (MRI) findings (tumor size, depth, and necrosis), positron emission tomography (PET) measures (SUVpeak, SUVmax, SUVmax tumor/SUVmean liver, and qualitative scale), and combinations of the above? Methods. All NF1 patients who underwent PET imaging at our institution (January 1, 2007–December 31, 2016) were included. Medical records were reviewed for clinical findings; MR images and PET images were interpreted by two fellowship-trained musculoskeletal and nuclear medicine radiologists, respectively. Receiver operating characteristic (ROC) curves were created for each PET measurement; the area under the curve (AUC) and thresholds for diagnosing malignancy were calculated. Logistic regression determined significant predictors of malignancy. Results. Our population of 41 patients contained 34 benign and 36 malignant tumors. Clinical findings did not reliably predict MPNST. Tumor depth below fascia was highly sensitive; larger tumors were more likely to be malignant but without a useful cutoff for diagnosis. Necrosis on MRI was highly accurate and was the only significant variable in the regression model. PET measures were highly accurate, with AUCs comparable and cutoff points consistent with prior studies. A diagnostic algorithm was created using MRI and PET findings. Conclusions. MRI and PET were more effective at diagnosing MPNST than clinical features. We created an algorithm for preoperative evaluation of peripheral nerve sheath tumors in NF1 patients, for which additional validation will be indicated.

Abstract:
Triple-negative breast cancer (TNBC) is treated with neoadjuvant chemotherapy (NAC). The response to NAC, particularly the probability of a complete pathological response (pCR), guides the surgical approach and adjuvant therapy. We developed a prediction model using a nomogram integrating blood tests and pre-treatment ultrasound findings for predicting pCR in patients with stage II or III operable TNBC receiving NAC. Clinical data before and after the first cycle of NAC collected from patients between 2012 and 2019 were analyzed using univariate and multivariate analyses to identify correlations with pCR. The coefficients of the significant parameters were calculated using logistic regression, and a nomogram was developed based on the logistic model to predict the probability of pCR. Eighty-eight patients were included. Five parameters correlated with the probability of pCR, including the neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte (PLR) ratio, percentage change in PLR, presence of echogenic halo, and tumor height-to-width ratio. The discrimination performance of the nomogram was indicated by an area under the curve of 87.7%, and internal validation showed that the chi-square value of the Hosmer–Lemeshow test was 7.67 (p = 0.363). Thus, the integrative prediction model using clinical data can predict the probability of pCR in patients with TNBC receiving NAC.

Abstract:
A hybrid finite element discrete mesoscopic approach is proposed to model the forming of composite parts using a unidirectional glass prepreg non-crimp fabric (NCF). The tensile behavior of the fabric is represented using 1-D beam elements, and the shearing behavior is captured using 2-D shell elements. The material is characterized using tensile and shear frame tests. These properties are then incorporated into an ABAQUS/Explicit finite element model via user-defined material subroutines. The shear frame characterization test is simulated using a finite element model of the fabric, and the finite element results are compared to experimental data as a validation of the methodology. The thermostamping of a double-dome geometry, which has been used in an international benchmarking program, is modeled as a demonstration of the capabilities of the proposed methodology.

Abstract:
To control pricing in passenger transportation, monitor the functioning of urban transport networks, reduce direct contacts during the COVID-19 pandemic, it is advisable to implement a system of NFC validation of fares. NFC (Near-Field Communication) technology provides primary information on public transport and travel fares. The article aims to improve the method of application of the technology of automated NFC-validation of fares in urban passenger transport to account for and control provided transport services. The tasks include research of mechanisms of the automated identification and counting of quantity of the transported passengers to account incomes of the motor transport enterprises; selection of calculation units for automated determination of the cost of provided transport services; development of control methods of drivers work, the operation of vehicles, transportation of privileged categories of citizens, pricing, etc. Theoretical and methodological aspects of NFC-validation technologies for public transport fares for accounting purposes have been studied based on general research methods – institutional and innovative; economic and mathematical methods of analysis and polynomial trend using Excel spreadsheets were used to predict the pace of implementation of NFC-devices; methods of bibliographic and comparative analysis using the information resource «ResearchGate»– to determine promising areas for new technologies in the provision of transport and passenger services. It is proved that the most effective unit of cost calculation of transport services is «passenger-kilometer», which corresponds to the peculiarities of the functioning of urban passenger transport, as it takes into account the number of passengers and distance of travel. The procedure for distribution of income from the sale of electronic tickets and budget subsidies between carriers based on information on the total number (including privileged categories) of transported passengers has been developed. The method of automated cost accounting by the «passenger-kilometer» meter for fuels and lubricants, staff salaries, depreciation of vehicles, and its current repairs, which define the cost of transport services, is improved. Implementing NFC fare validation technology will facilitate automated accounting of costs, revenues, and cash receipts from transport services, the introduction of effective control over the work of drivers, vehicles, concessional transportation, pricing, timeliness, and reliability taxes on urban transport.

Abstract:
The high specific stiffness and strength of composites makes it advantageous for load carrying structures in the automotive industry. By successfully be able to numerically simulate the crush behaviour of composites, structure with high specific energy absorption can be implemented in the automotive industry. The purpose of this thesis is to verify the predictive capabilities of a crush model developed at SICOMP. Initially currently available material models are investigated. Puck’s criterion is deeper studied. An improvement of the criterion is suggested and the model is updated to be able to output fracture angles in Abaqus.The material model developed by SICOMP is a three-dimensional physically based damage model where failure initiation is estimated with proven failure criteria and damage growth is combined with friction to account for the right energy absorption. The crush damage model has been implemented in Abaqus/Explicit as a VUMAT subroutine. Numerical predictions are compared with experimental results. Specimens with different fibre layups and crash triggers are tested.

Abstract:
A brief history is provided of Aphasia testing. The test batteries published since 1947 are described under the following formal headings: theory and classification, organisation, quantification, charting and interpretation, and standardisation and factor analyses. A component analysis of the forty aphasia test batteries is conducted. The most frequently used subtests are identified and divided into subgroups of tests, tests of auditory comprehension, oral language, naming, reading comprehension, speech production, written language and non-language tasks. The fifty most frequently used subtests are then applied to a group of normal elderly people to establish baseline norms. Then 108 diagnosed aphasic patients are subjected to these same tests, and the results analysed. The patient data, the normal data and the tests thelllSelves are examined. Xethods of analysis include factor analYSiS, discriminant analysis and cluster analysis. Analysis of variance is applied to the elderly normal subj ects and the aphasic patients, as well as to the aphasic patients on repeated measures. Conclusions are then drawn about how effective the most frequently used subtests in aphasia batteries are in identifying the degree and type of language disturbance in aphasic patients.

Abstract:
This study aims to validate a screw joint simulation model used by BAE Systems in LS-DYNA during blast simulations. It is important that the screw joint simulation model is physically correct, since the simulation results can influence major design decisions. The study provides a short overview on the subject of bolts and screws, material deformation and stress and strain in materials, of the finite element method (FEM) and on some specific numerical methods used in this study. BAE Systems started a validation project of the screw joint simulation model in 2015, but it was not finished due to other priorities. In this older project some drop-tower tests measuring the axial force in a screw joint were conducted. These old tests can now serve as validation data for the screw joint simulation model. The screw joint simulation model used by BAE Systems is dependent on a special kind of finite element formulation; a so called beam element. This study provides a finite element analysis on this simulation model, which is implemented through an established industry FEM solver called LS-DYNA. The validation of the screw joint simulation model is done against three drop-tower experiments performed at 900, 1000 and 1100mm drop height respectively. The drop-tower experiments were replicated in LS-DYNA, with a prescribed velocity on the falling parts rather than simulating a free fall and non-elastic impact. A comparison between the simulation model using beam elements, that is used by BAE Systems, and a similar simulation model using solid elements is presented as part of the validation. To make sure that the result of the study is confident, a local mesh convergence study and a study of the mass scaling numerical method in LS-DYNA is also presented. The results show that the screw joint simulation model using beam elements is valid according to the available experimental data. In one of the experiments, where the drop-test was performed twice, an average maximum force on the screw was measured to be 33.5+-4.8 kN. Simulations of the same case, under the same conditions, using beam elements resulted in a maximum force on the screw of 35.4 kN, well within the experimental result range. In the other two drop-tower experiments, the simulated results showed correlation considering the error sources in the simulation model and the statistical spread that is present in the experimental results. The simulation model using beam elements is also similar to the results using solid elements, which also indicates that the beam model is valid. All in all, it is shown that the beam model can be used to produce safe results that either overestimate or place the simulations of the axial force in the screw in the upper spread of the measurements.

Dans cette étude, une adaptation francophone du PNI (le ENP) a été développée puis validée auprès de deux échantillons de la population soit normal ainsi que clinique. Les résultats ont permis de démontrer des associations congruentes à celles obtenues par l’équipe de Pincus et ses collaborateurs (2009) quant à la version originale. Ainsi, le ENP a démontré des associations positives avec deux autres mesures du narcissisme (le NPI et le HSNS). Des associations significatives avec divers autres mesures normalement associées au narcissisme pathologique ont également été détectées (estime de soi, machiavélisme et indices d’organisation limite de la personnalité). Des différences significatives entre l’échantillon normal et clinique ont pu être mesurées ainsi qu’une utilisation indifférenciée à travers les genres semble possible.

Abstract:
This study developed and validated the Berke Prenatal Anxiety Questionnaire, created to measure prenatal anxiety. Scores from 301 pregnant women in various stages of pregnancy were used to determine the internal consistency of the Berke Prenatal Anxiety Questionnaire. These women were recruited in obstetric offices and hospitals across California. Coefficient alpha for the total scale was.87. Factor analysis showed that the items did not really cluster together in three groups as expected. Two approaches were undertaken to develop a new definition, in order to revise the scale. Three one-way ANOVA with trimester of pregnancy as the between subjects variable were calculated on the total scale and revised scales scores from the questionnaire and no significant differences were found. This questionnaire needs additional validation though the creation of new items characterizing the revised definitions. Eventually, in a revised form, this questionnaire can be used in additional research and in a clinical setting to identify pregnant women experiencing high levels of maladaptive prenatal anxiety. Efforts could then be made to reduce their anxiety, which can benefit both the mother and her infant.

Abstract:
The Tiltrotor Test Rig (TTR) was tested in the National Full-Scale Aerodynamics Complex (NFAC) 40- by 80-FootWind Tunnel from 2017 to 2018. The primary goal of the test was to understand the operational capabilities of the TTR, while also acquiring research data, including acoustic data. Four microphones were placed around the TTR: two on the wind tunnel floor and two on struts. Acoustic measurements of the TTR rotor were acquired to 1) understand the acoustic testing capabilities of the TTR in the NFAC 40- by 80-FootWind Tunnel, 2) compare to previous XV-15 rotor acoustic data acquired in the NFAC 80- by 120-Foot Wind Tunnel, and 3) provide data for future validation studies. A data quality study revealed that the NFAC 40- by 80-Foot Wind Tunnel is an adequate acoustic environment to test the TTR rotor. For a given thrust and advance ratio, a shaft angle sweep was performed and acoustic measurements were compared against 1996 and 1999 XV-15 data in the NFAC 80- by 120-Foot Wind Tunnel; differences between the three tests are discussed.

Abstract:
Abstract In 2005, NGC, Petrotrin and Repsol E&P T&T Ltd. as joint venture partners, acquired the TSP asset with Repsol as the operator. The three fields, Teak, Samaan and Poui, have been in production for over 40 years and are highly complex, extremely compartmentalized and consist of over 10 different sands and reservoirs. Over 100 PVT files for the three fields are available; most of which were done in the 1970's by different labs using different protocols and procedures. All files were handed over in paper form which needed digitization as well as validation. Valid PVT data provides vital information for the characterization of reservoir fluids. The establishment of fluids' physical and PVT properties help determine in situ and stock tank volumes, strategies for production, flow assurance issues for facilities design and provides guidelines for effective and efficient reservoir management throughout the life of the asset. Numerous techniques exist for assessing and evaluating the quality of PVT data. This paper will describe the best practices used to validate TSP PVT data, such as the material balance tests and the Y-function linearity tests as well as the applications of the validated data through examples and case studies. Some of which include the development of trends which can be extrapolated for use in new prospects, infill and developmental drilling. Additional benefits include the recognition of flow assurance issues such as wax and sulphur compounds and the sampling and design of relevant PVT experiments for new wells. Production history combined with valid PVT data provides a powerful tool to help in the prediction of expected fluid types and fluid behaviour as pressure changes in planned new wells. It also provides additional technical support for which improvements to the fluid sampling program can be made to acquire the most representative fluid samples from the reservoir.

Abstract:
Common quarter-turn (QT) mechanisms used in nuclear plant air-operated valves (AOVs) include scotch yoke, lever, and link-and-lever mechanisms coupled to diaphragms and pistons. QT mechanism efficiency varies as a function of valve position and is a critical design input used to determine AOV margin. Because of the lack of publicly available data of a quality commensurate with “nuclear QA [quality assurance],” Kalsi Engineering, Inc. (KEI), initiated an independent QT-mechanism efficiency test program that includes a number of commonly used actuator manufacturers, models, and sizes based on a survey of U.S. nuclear power plants. The first test specimen was a diaphragm actuator with a lever QT mechanism. The diaphragm rod of the test specimen was instrumented with strain gauges so that a direct measurement of the net actuator force transmitted to the QT mechanism could be measured. In addition to the net thrust, the output torque, diaphragm pressure, and actuator position were measured. Measuring the net thrust, diaphragm pressure, and position allowed the spring rate, spring preload, and effective diaphragm area to be quantified. This test specimen was tested using two different types of bearings at the actuator shaft-to-lever connection. Needle bearings were used to provide torque results for a nearly frictionless QT mechanism, and bronze bearings were used to simulate a more realistic QT-mechanism configuration. Predictions made using the first-principles efficiency model are compared to efficiencies extracted from test. The predicted efficiency using a realistic range for the friction coefficient of the bronze bearings is in good agreement with the extracted efficiencies. Paper published with permission.

Abstract:
This deliverable focus on the verification and validation of the solvers of Kratos Multiphysics which are used within ExaQUte. These solvers comprise standard body-fitted approaches and novel embedded approaches for the Computational Fluid Dynamics (CFD) simulations carried out within ExaQUte. Firstly, the standard body-fitted CFD solver is validated on a benchmark problem of high rise building - CAARC benchmark and subsequently the novel embedded CFD solver is verified against the solution of the body-fitted solver. Especially for the novel embedded approach, a workflow is presented on which the exact parameterized Computer-Aided Design (CAD) model is used in an efficient manner for the underlying CFD simulations. It includes: A note on the space-time methods Verification results for the body-fitted solver based on the CAARC benchmark Workflow consisting of importing an exact CAD model, tessellating it and performing embedded CFD on it Verification results for the embedded solver based on a high-rise building API definition and usage
