Chatter Analysis of Machining Systems With Nonlinear Force Processes

Regenerative chatter is a major limitation to the productivity and quality of machining operations owing to the poor surface finish, excessive tool wear, and reduced dimensional accuracy which are produced. Machining chatter analysis techniques examine the stability of the closed-loop model of the machining operation. This model is the combination of a force process model and a tool-workpiece structure model. Almost all chatter analysis techniques assume a linear force process although machining force processes inherently contain nonlinearities with respect to the cutting parameters (i.e., feed, depth-of-cut, and cutting speed). A novel machining chatter analysis approach is introduced for the stability analysis of machining systems with nonlinear force processes. The accuracy of this methodology is validated via comparisons to time domain simulations and experiments. The stability lobe diagrams (i.e., plots of the stable and unstable regions in the cutting parameter space) generated using linear and nonlinear force process models are compared and the machining force process nonlinearities are shown to significantly impact the resulting diagrams.
Cognition and Distributed Cognition in Software Engineering Research [WIP]

The purpose of this paper is to conduct an exploratory literature review in the area of cognition and distributed cognition within software engineering (SE) research. Over arching aims of this literature review are to understand the how individual cognition and distributed cognition are discussed in software engineering research. This is to support empirical studies on the role cognition (individual or team) plays during software development process. The ﬁnding suggest that most of the research to date is empirical but there is also some theoretical research. The research focus has been on: program comprehension, design and review, distributed cognition and how tools can reduce cognitive load for programmers. This analysis provides opportunities for further research in terms of cognitive models and methodological insights.
Recent Developments in Additive Manufacturing of Gears: A Review

Additive Layer Manufacturing (ALM) is an advanced technology to produce quality gears of metals and plastics. Some significant benefits such as capability to handle complex gear shapes and design, and produce near net-shaped gears; resource efficiency; and rapid product development etc. make this process a sustainable alternate to the other processes of gear manufacturing. This paper sheds light on the development of some of the important additive layer manufacturing processes such as Stereolithography, Fused Deposition Modeling, and 3D Printing to manufacture gears. The article aims to facilitate researchers and encourages them to do further research and development for improved gear quality, process productivity, and sustainability.
Eliciting Speculative Design Fictions from the Margins

One approach to constructing an inclusive taxonomy of design ﬁctions is to assess and understand whose voices have been missing from these narratives and why. We must then understand how our approaches and methods to eliciting such narratives could be more inclusive. To begin these eﬀorts, we reﬂect on past HCI work, as well as our own, and discuss new methods, approaches, and questions to consider going forward to elicit more inclusive narratives. Through feedback sessions, which we hope to receive in the Design Fictions Workshop, we plan to iterate on and execute our proposed work with individuals from ethnically-diverse and marginalized groups.
Kinect Based System and Serious Game Motivating Approach for Physiotherapy Assessment and Remote Session Monitoring

Abstract This paper describes a framework focused on being a health monitoring platform as well as a source of entertainment for physiotherapy patients, particularly stroke survivors. Using the Microsoft Kinect sensor a serious game captures 3D data during the patient’s session and sends it to a server. Through a web application these data can be further visualized by the physiotherapists on their assessments. Moreover, this framework intends to be a useful and effective tool for remote physiotherapy sessions allowing for a considerable cost reduction. Experimental results related to arms and shoulders rehabilitation are included in this paper.
Diffuse Intrinsic Pontine Glioma: Molecular Landscape, Evolving Treatment Strategies and Emerging Clinical Trials

Diffuse intrinsic pontine glioma (DIPG) is a type of intrinsic brainstem glial tumor that occurs primarily in the pediatric population. DIPG is initially diagnosed based on clinical symptoms and the characteristic location on imaging. Histologically, these tumors are characterized by a heterogenous population of cells with multiple genetic mutations and high infiltrative capacity. The most common mutation seen in this group is a lysine to methionine point mutation seen at position 27 (K27M) within histone 3 (H3). Tumors with the H3 K27M mutation, are considered grade 4 and are now categorized within the H3 K27-altered diffuse midline glioma category by World Health Organization classification. Due to its critical location and aggressive nature, DIPG is resistant to the most eradicative treatment and is universally fatal; however, modern advances in the surgical techniques resulting in safe biopsy of the lesion have significantly improved our understanding of this disease at the molecular level. Genomic analysis has shown several mutations that play a role in the pathophysiology of the disease and can be targeted therapeutically. In this review, we will elaborate on DIPG from general aspects and the evolving molecular landscape. We will also review innovative therapeutic options that have been trialed along with new promising treatments on the horizon.
Understanding the joint impacts of soil architecture and microbial dynamics on soil functions: Insights derived from microscale models

Over the last decades, a new generation of microscale models has been developed to simulate soil microbial activity. An earlier article (Pot et al., 2021) presented a detailed review of the description of soil architecture and microbial dynamics in these models. In the present article, we summarise the main results obtained by these models according to six model outputs: growth and spatial organisation of microbial colonies, soil hydraulic conductivity, coexistence and trophic interactions of microorganisms, temporal dynamics of the amount of solid and dissolved organic matter in soil and, microbial production of CO2. For each of these outputs, we draw particular attention to the respective roles of soil architecture and microbial dynamics, and we report how microscale models allow for disentangling and quantifying them. We finally discuss limitations and future directions of microscale models in combination with the on‐going development of high‐performance imaging tools revealing the spatial heterogeneity of the actors of soil microbial activity.
Physical Demands during the Game and Compensatory Training Session (MD + 1) in Elite Football Players Using Global Positioning System Device

The aims of this study were to analyze the differences of physical demands of non-starter players regarding the playing time during the competition and to evaluate the physical demands of the compensatory training (MD + 1C) for substitute players in elite football. The match statistics and MD + 1C of substitute players from a professional Spanish LaLiga football club were analyzed using a 10-Hz global positioning system (GPS) Apex GPS system device, which has been validated as a reliable and valid method to analyze performance in team sports, during all games of the 2016/2017, 2017/2018 and 2018/2019 seasons. The starting players showed both lower total distances covered and high-intensity actions compared to the substitutes. Regarding the minutes played by the substitutes, greater physical performance was found for the players with fewer minutes (5–15 min). Furthermore, no differences were found between first and second divisions regarding physical performance of substitutes (p > 0.05). This study highlights the importance of individualizing the workload of training sessions for substitutes and starters. Furthermore, the complementary session should be individualized according to the minutes played by the substitutes. These players are potentially under-loaded compared to starters, especially in terms of high-intensity actions, therefore additional session-specific training for each substitute would be useful to reach the optimal training load according to the minutes played during the game.
A narrative review on the application of doubly labeled water method for estimating energy requirement for Koreans

Research articles were reviewed to validate the estimated energy requirements (EERs) equations developed by the Institute of Medicine of the National Academies (IOM). These equations are based on total energy expenditure (TEE) measured by the doubly labeled water (DLW) method. We subsequently aimed to provide the basis for the suitability to apply the IOM equations as EER equations for Koreans, and develop relevant equations for EER in the Dietary Reference Intake for Koreans (KDRI). Additionally, besides the EER(IOM) equations, other equations were examined for EER estimation. Research papers demonstrating the validation of the EER(IOM) equations based on TEE(DLW) were searched through PubMed (up to September 2019). Of the 637 potentially relevant articles identified, duplicates and unsuitable titles and abstracts were excluded. Furthermore, papers with irrelevant subject and inappropriate study design were also excluded. Finally, 11 papers were included in the review. Among the reviewed papers, 8 papers validated the application of the EER(IOM) equations for EER based on TEE(DLW). These included 3 studies for children (USA 1, Korea 2), 1 for adolescents (Portugal), 2 for adults (Korean), and 2 for the elderly (Korea, USA). EER(IOM) equations were found to be generally acceptable for determining EER by using the DLW method, except for Korean boys at 9–11 yrs (overestimated) and female athletes at 19–24 yrs (underestimated). Additionally, 5 papers include the validation of other EER equations, beside EER(IOM) for EER based on TEE(DLW). In Japanese dietary reference intake and recommended dietary allowance, EER equations are acceptable for determining EER based on TEE(DLW). The EER(IOM) equations is generally acceptable for determining EER using the DLW method in Koreans as well as several populations, although certain defined groups were found to be unfit for the estimation. Additionally, the concept of healthy body mass index of Koreans and physical activity levels need to be considered, thereby providing the basis for developing relevant equations of EER in KDRI.

Aflatoxin M1 Contamination of Ghanaian Traditional Soft Cottage Cheese (Wagashie) and Health Risks Associated with Its Consumption

Wagashie is an unripened traditional cheese consumed in West Africa including Ghana. Being a milk product, it is unfortunately susceptible to aflatoxin M1 (AFM1) contamination, which is indeed a grave health challenge globally. This study evaluated AFM1 levels and health risk characterization associated with wagashie (n = 182) sampled from different locations in Ghana. AFM1 was measured with high-performance liquid chromatography with a fluorescence detector (HPLC-FLD). Risk assessments were also conducted using models prescribed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Out of the 182 samples analyzed for AFM1, 93/182 (51.1%) tested positive between the range 0.00 ± 0.00–3.60 ± 0.99 µg/kg. Risk assessments of AFM1 using deterministic models produced outcomes that ranged between 0.11 and 3.60 ng/kg bw/day, 0.09–1.54, 0–0.0323 ng aflatoxins/kg bw/day, and 3.5 x 10−3 −0.06 cases/100,000 person/yr for estimated daily intake (EDI), margin of exposure (MOE), average potency, and cancer risks, respectively, for the age categories investigated. It was established that the consumption of wagashie posed adverse health effects on all age categories in the selected regions of the study because all calculated MOE values were less than 100,000. Therefore, contamination of wagashie with AFM1 should be a serious public health concern and as such considered a high precedence for Ghana’s risk management actions.
The Metrology Job Description Initiative: NCSLI and ASQ Partnering for the Future

Abstract: If you talk to almost any person involved in the metrology profession about new talent entering the field, you'll probably get the same response: “There are not enough young people entering the field to replace the many baby boomers getting ready to retire. ” At the heart of this alarming observation is the lack of metrology awareness amongst young adults poised to make career decisions that will in many cases determine their lifelong profession. To assist young adults in making well informed career decisions, educators frequently reference U.S. Department of Labor publications in order to provide information about professions and forecasts of future job growth. This paper will discuss the joint efforts of NCSL International and the American Society for Quality's Measurement Quality Division to increase awareness of the metrology profession, and to thereby increase the likelihood that young adults will pursue a career in metrology. These efforts resulted in the development of three job descriptions: Calibration Technician; Calibration Engineer; and Metrologist.
Application Research of Tooth Arrangement Based on Rotation Matrix Calculation and Resistance Detection in Oral

The goal of this research was to provide a new approach for analyzing orthodontic teeth arrangement inside oral depending on the rotation matrix computation and resistance detection. The present method includes the following operations within a certain therapy period: first three-dimensional positions of the tooth were evaluated with a pierced laser beam and a three-dimensional system of surface-scanning. Second, the three-dimensional shape data was automatically registered at maxillary 1st molars, and methods of coordinate had been normalized. Third, a translation vector and rotation matrix had been evaluated from automatic registration of two position data of a particular tooth. Fourth, the limited spiral axes of teeth had been measured as the zero rotational dislocation locus; and impressions for a model of the dental cast had been taken at five different points: shortly before and after device was fitted, and ten days, one month, and two months after the treatment started. The results showed that existing analysis approach could more quickly classify a specific tooth's movement by spinning all over and translating along a finite helical axis. It can provide statistical visual three-dimensional data on complex tooth arrangement throughout orthodontic therapy.
Exploring the effects of tuned mass dampers on the seismic performance of structures with nonlinear base isolation systems

Base isolation is a quite practical control strategy for enhancing the response of structural systems induced by strong ground motions. Due to the dynamic effects of base isolation systems, reduction in the interstory drifts of the superstructure is often achieved at the expense of high base displacement level, which may lead to instability of the structure or non-practical designs for the base isolators. To reduce the base displacement, several hybrid structural control strategies have been studied over the past decades. This study investigates a particular strategy that employs Tuned Mass Dampers (TMDs) for improving the performance of base-isolated structures and unlike previous studies, specifically focuses on the effectiveness of this hybrid control strategy in structures that are equipped with nonlinear base isolation systems. To consider the nonlinearities of base isolation systems, a Bouc-Wen model is selected and nonlinear dynamic OpenSees models are used to perform several time-history simulations in time and frequency domains. Through these numerical simulations, the effects of several parameters such as the fundamental period of the structure, dynamic properties of the TMD and isolation systems and properties of the input ground motion on the behaviour of TMD-structure-base isolation systems are examined. The results of this study provide a better insight into the performance of linear shear-story structures with nonlinear base isolators and show that there are many scenarios in which TMDs can still improve the performance of these systems.
Effectiveness of “Internet+” Based Cardiac Rehabilitation on Prognosis of Patients with Coronary Heart Disease: A Meta-Analysis

Objective Meta-analysis was used to systematically evaluate the impact of Internet-based cardiac rehabilitation on the health of patients with coronary heart disease. Methods Randomized controlled trial study (RCTs) of the effects of Internet-based cardiac rehabilitation on cardiovascular risk factors, motor function and psychological status in patients with coronary heart disease has been systematically studied. Results A total of 13 articles were included. Meta-analysis showed that internet-based cardiac rehabilitation training could effectively reduce the total cholesterol level [MD = -0.15, 95% CI (-0.28, -0.02), P = 0.02] and triglyceride level [MD = -0.19, 95% CI (-0.32, -0.06), P = 0.01], increase the maximal oxygen uptake (VO2 max) [MD = 0.9995, CI (0.161.83) P = 0.02] and physical activity level [SMD = 0.51, 95% CI (0.07, 0.9), P = 0.02], and improve the self-efficacy [SMD = 0.50, 95% CI (0.17, 0.83), P = 0.01] and improved quality of life [SMD = 1.34, 95% CI (0.12, 2.56), P = 0.03] of patients. However, there was no significant improvement in blood pressure and body mass index, depression and anxiety. Conclusion Internet-based cardiac rehabilitation can significantly reduce cholesterol and triglyceride levels and improve theVO2 max, physical activity, self-efficacy and quality of life, but is not effective on the level of blood pressure, BMI, anxiety and depression. Due to the limitations of methodological quality and sample size of included studies, more studies with high-quality and large sample are needed to further evaluate its effectiveness.
Combined CFD-Stochastic Analysis of an Active Fluidic Injection System for Jet Noise Reduction

In the framework of DANTE project (Development of Aero-Vibroacoustics Numerical and Technical Expertise), funded under the Italian Aerospace Research Program (PRORA), the prediction and reduction of noise from subsonic jets through the reconstruction of turbulent fields from Reynolds Averaged Navier Stokes (RANS) calculations are addressed. This approach, known as Stochastic Noise Generation and Radiation (SNGR), reconstructs the turbulent velocity fluctuations by RANS fields and calculates the source terms of Vortex Sound acoustic analogy. In the first part of this work, numerical and experimental jet-noise test cases have been reproduced by means RANS simulations and with different turbulence models in order to validate the approach for its subsequent use as a design tool. The noise spectra, predicted with SNGR, are in good agreement with both the experimental data and the results of Large-Eddy Simulations (LES). In the last part of this work, an active fluid injection technique, based on extractions from turbine and injections of high-pressure gas into the main stream of exhausts, has been proposed and finally assessed with the aim of reducing the jet-noise through the mixing and breaking of the turbulent eddies. Some tests have been carried out in order to set the best design parameters in terms of mass flow rate and injection velocity and to design the system functionalities. The SNGR method is, therefore, suitable to be used for the early design phase of jet-noise reduction technologies and a right combination of the fluid injection design parameters allows for a reduction of the jet-noise to 3.5 dB, as compared to the baseline case without injections.
Constipation Symptoms in Multiple System Atrophy Using Rome Criteria and Their Impact on Personalized Medicine

Constipation is one of the most common non-motor symptoms in multiple system atrophy (MSA); however, it has not been evaluated according to the standard diagnostic criteria for constipation in patients with MSA. We evaluated the characteristics of constipation in patients with MSA by using Rome criteria (Rome III), which has been validated and the widely used for gastrointestinal disorders. Fifty-one patients with MSA (29 female) were enrolled in the study. Based on the Rome III criteria, constipation was diagnosed in 29 patients (56.9%); irritable bowel syndrome was not detected. Thirty-seven patients (72.5%) were aware of their constipation. The most common constipation symptom was the sensation of anorectal obstruction (68.6%). Patients’ self-awareness of constipation was most strongly correlated to the sensation of incomplete evacuation (odds ratio: 7.377, 95% confidence interval: 1.402–38.817). The number of constipation-related symptoms was correlated with the total levodopa equivalent dose (p < 0.05). Rome criteria, which can detect various constipation symptoms, are useful for evaluating constipation in MSA, and these findings may greatly impact personalized medicine.
Testing Potential Transfer Effects in Heritage and Adult L2 Bilinguals Acquiring a Mini Grammar as an Additional Language: An ERP Approach

Models on L3/Ln acquisition differ with respect to how they envisage degree (holistic vs. selective transfer of the L1, L2 or both) and/or timing (initial stages vs. development) of how the influence of source languages unfolds. This study uses EEG/ERPs to examine these models, bringing together two types of bilinguals: heritage speakers (HSs) (Italian-German, n = 15) compared to adult L2 learners (L1 German, L2 English, n = 28) learning L3/Ln Latin. Participants were trained on a selected Latin lexicon over two sessions and, afterward, on two grammatical properties: case (similar between German and Latin) and adjective–noun order (similar between Italian and Latin). Neurophysiological findings show an N200/N400 deflection for the HSs in case morphology and a P600 effect for the German L2 group in adjectival position. None of the current L3/Ln models predict the observed results, which questions the appropriateness of this methodology. Nevertheless, the results are illustrative of differences in how HSs and L2 learners approach the very initial stages of additional language learning, the implications of which are discussed.
