Modeling and optimization for surface roughness and tool flank wear in hard turning of AISI 4340 steel (35 HRC) using TiSiN-TiAlN nanolaminate coated insert
Authors: Kaladhar M. 
Published: July 2020

PurposeThe present study spotlights the single and multicriteria decision-making (MCDM) methods to determine the optimal machining conditions and the predictive modeling for surface roughness (Ra) and cutting tool flank wear (VB) while hard turning of AISI 4340 steel (35 HRC) under dry environment.Design/methodology/approachIn this study, Taguchi L16 design of experiments methodology was chosen. The experiments were performed under dry machining conditions using TiSiN-TiAlN nanolaminate PVD-coated cutting tool on which Taguchi and responses surface methodology (RSM) for single objective optimization and MCDM methods like the multi-objective optimization by ratio analysis (MOORA) were applied to attain optimal set of machining parameters. The predictive models for each response and multiresponse were developed using RSM-based regression analysis. S/N ratios, analysis of variance (ANOVA), Pareto diagram, Tukey's HSD test were carried out on experimental data for profound analysis.FindingsOptimal set of machining parameters were obtained as cutting speed: at 180 m/min., feed rate: 0.05 mm/rev., and depth of cut: 0.15 mm; cutting speed: 145 m/min., feed rate: 0.20 mm/rev. and depth of cut: 0.1 mm for Ra and VB, respectively. ANOVA showed feed rate (96.97%) and cutting speed (58.9%) are dominant factors for Ra and VB, respectively. A remarkable improvement observed in Ra (64.05%) and VB (69.94%) after conducting confirmation tests. The results obtained through the MOORA method showed the optimal set of machining parameters (cutting speed = 180 m/min, feed rate = 0.15 mm/rev and depth of cut = 0.25 mm) for minimizing the Ra and VB.Originality/valueThis work contributes to realistic application for manufacturing industries those dealing with AISI 4340 steel of 35 HRC. The research contribution of present work including the predictive models will provide some useful guidelines in the field of manufacturing, in particular, manufacturing of gear shafts for power transmission, turbine shafts, fasteners, etc.
Influence of aging on microstructure and hardness of lead-free solder alloys
Authors: Morando Carina , Fornaro Osvaldo 
Published: July 2020

Purpose
The purpose of this paper is to carry out a study of the evolution of the microstructure and the microhardness of Sn-Cu-Ag alloys from as-cast condition and under artificial isothermal aging at different temperatures (100ºC and 180ºC) for a treatment time up to 500 h. A comparison with Sn-37% Pb eutectic solder samples was also made.

Design/methodology/approach
Sn-3.5%Ag, Sn-0.7%Cu and Sn-3.5%Ag-0.9%Cu were poured in two different cooling rate conditions and then aged at 100ºC (373ºK) and 180 °C (453ºK) during 500 h. Microstructural changes were observed by optical microscopy, scanning electron micrograph and energy dispersive X-ray microanalysis. Differential scanning calorimetry technique (DSC) was also used to confirm the obtained results.

Findings
A decrease up to 20% in microhardness respect to the value of the as-cast alloy was observed for both aging temperatures. These changes can be explained considering the coarsening and recrystallization of Sn dendrites present in the microstructures of all the systems studied.

Originality/value
There is no evidence of dissolution or precipitation of new phases in the range of studied temperatures that could be detected by DSC calorimetry technique. The acting mechanisms must be the result of coarsening of Sn dendrites and the residual stresses relaxation during the first stages of the isothermal aging.

Published: July 2020

PurposeThe study aims at empirically investigating and prioritizing the critical barriers for the successful implementation of agile manufacturing in the medium- and large-scale Indian manufacturing industries.Design/methodology/approachA literature review of peer-reviewed journals and discussion with experts is used to identify 17 barriers to the implementation of agile manufacturing. An empirical survey is then conducted to collect data regarding the agile manufacturing barriers and is further analyzed using the factor analysis and vlsekriterijumska optimizacija i kompromisno resenje (VIKOR).FindingsBased on the survey of empirical data, the investigated critical barriers were reduced in five critical categories, as follows: Managerial constraints, technological constraints, human resource–related constraints, operational constraints and organizational culture-related constraints, which are further ranked in terms of their severity using VIKOR. This research advocates the development of a strategy for addressing the most critical barriers instead of focusing on all for the successful implementation of agile manufacturing.Originality/valueThis work contributes to agile manufacturing literature by the structured presentation of the barriers to implement agile manufacturing in the Indian manufacturing industry. It also extends the integrated factor analysis and VIKOR method to investigate and rank the barriers.
Inbound and Outbound Globalizations in the International Film Industry
Authors: Kim Shin Dong , Parc Jimmyn 
Published: July 2020

AbstractSince culture has been considered as a pillar of national identity, prevailing ideas for cultural industries and policies are closely linked to protectionism and anti‐globalization. However, these moves are derived from a narrow understanding of globalization. In this regard, this paper deals with this fundamental question on how to understand globalization in cultural industries with a focus on the film sector. For this research question, this paper identified inbound and outbound globalizations. Inbound globalization happens domestically with the interconnectedness among domestic and international factors whereas outbound globalization occurs overseas. These two types of globalizations can be undertaken both actively and passively depending on how to utilize (dis)advantages. Based on such an analysis, this paper argues that government policies should be set up to maximize benefits from both inbound and outbound globalizations in order to enhance the international competitiveness of the film industry while strengthening its industrial base.
Target Hollywood! Examining Japan’s Film Import Ban in the 1930s
Authors: Ranger Stephen 
Published: July 2020

AbstractIn the 1930s Hollywood enjoyed a popular following in the Japanese film market, accounting for almost 90 per cent of imported sound films. Against a backdrop of emerging political tensions and war in China, the Japanese government announced in 1937 that it would place a ban on Hollywood film imports. This was a move that ushered in a new era of protectionism for Japan’s emerging film industry. Following this decision, Hollywood studios engaged with Tokyo and sought an agreement to ease the new restrictions. After a period of intense discussions, the Japanese government agreed to lift the ban albeit with certain conditions. This paper examines protectionism in the Japanese film market and considers the impact of political forces, both domestic and international, on the decisions made. It will show that economic factors were mostly behind the decision to implement the ban and therefore facilitated the reaching of an agreement between the two sides. Furthermore, the interests of the domestic film industry who would benefit from the import of Hollywood films helped lift the ban.
Overcoming the Incoherent ‘Grand Maneuver’ in the French Film and TV Markets: Lessons from the Experiences in France and Korea
Authors: Parc Jimmyn , Messerlin Patrick 
Published: July 2020

AbstractIn 1989, the Member States of the European Union integrated their TV markets together in order to create a larger and more open ‘single TV market’ through the Television without Frontiers Directive. The French film industry used this opportunity to extract additional revenues by implementing TV quotas and strengthening the chronologie des médias. This paper examines the impact of these two measures on the French film and TV industries and shows how they were incoherent. In contrast to the expectations of the French film industry, these measures have induced it to produce less attractive films and burdened the TV industry with increased regulatory costs. While the government poured massive subsidies into the filmmaking sector, this endeavor has not been able to significantly improve the attractiveness of French films. In this regard, the Korean film industry offers valuable lessons. Since the late 1990s, the Korean government has significantly reduced its level of protectionism and scaled back its intervention in the industry. Crucially, business has been the main engine to produce attractive films that can compete with Hollywood films in the open market. For the French film industry, the findings in this paper suggest which direction its Grandes Manœuvres should pursue.

AbstractBackgroundAtopic dermatitis (AD) patients are often colonized with Staphylococcus aureus, and staphylococcal biofilms have been reported on adult AD skin lesions. The commensal S epidermidis can antagonize S aureus, although its role in AD is unclear. We sought to characterize S aureus and S epidermidis colonization and biofilm propensity and determine their associations with AD severity, barrier function, and epidermal gene expression in the first US early‐life cohort of children with AD, the Mechanisms of Progression of Atopic Dermatitis to Asthma in Children (MPAACH).MethodsThe biofilm propensity of staphylococcal isolates was assessed by crystal violet assays. Gene expression of filaggrin and antimicrobial alarmins S100A8 and S100A9 was measured in keratinocyte RNA extracted from skin tape strips. Staphylococcal biofilms sampled from MPAACH skin were visualized using scanning electron microscopy.ResultsSixty‐two percent of staphylococcal isolates (sampled from 400 subjects) formed moderate/strong biofilms. Sixty‐eight percent of subjects co‐colonized with both staphylococcal species exhibited strains that formed cooperative mixed‐species biofilms. Scanning electron microscopy verified the presence of staphylococcal biofilms on the skin of MPAACH children. Staphylococcus aureus strains showing higher relative biofilm propensity compared with S epidermidis were associated with increased AD severity (P = .03) and increased lesional and nonlesional transepidermal water loss (P = .01, P = .03).ConclusionsOur data suggest a pathogenic role for S aureus biofilms in AD. We found that strain‐level variation in staphylococcal isolates governs the interactions between S epidermidis and S aureus and that the balance between these two species, and their biofilm propensity, has important implications for AD.
A counterpoint paper: Comments on the electrocardiographic part of the 2018 Fourth Universal Definition of Myocardial Infarction endorsed by the International Society of Electrocardiology and the International Society for Holter and Noninvasive Electrocardiology

AbstractThe Fourth Universal Definition of Myocardial Infarction (FUDMI) focuses on the distinction between nonischemic myocardial injury and myocardial infarction (MI), along with the role of cardiovascular magnetic resonance, in order to define the etiology of myocardial injury. As a consequence, there is less emphasis on updating the parts of the definition concerning the electrocardiographic (ECG) changes related to MI. Evidence of myocardial ischemia is a prerequisite for the diagnosis of MI, and the ECG is the main available tool for (a) detecting acute ischemia, (b) triage, and (c) risk stratification upon presentation. This review focuses on multiple aspects of ECG interpretation that we firmly believe should be considered for incorporation in any future update to the Universal Definition of MI.

Published: July 2020

AbstractIntroductionMedical quality registries have gained popularity as tools for monitoring the quality of medical treatments and they serve as data sources for research. The Norwegian Female Incontinence Registry (NFIR) was established in 1998 to monitor and improve the quality of surgery for women with stress and mixed urinary incontinence in Norway and to collect data for research. This study aimed to assess the completeness and accuracy of the Norwegian Female Incontinence Registry, and potential differences in data accuracy over time and according to surgical volume of the reporting hospitals.Material and methodsA random selection of 300 women from a total of 20 610 operated for urinary incontinence between 1998 and 2016 reported to the Norwegian Female Incontinence Registry from 28 public hospitals were selected for validation. The database completeness was estimated for 2008‐2017 by comparing surgical procedures registered both in the Norwegian Female Incontinence Registry and the Norwegian National Patient Registry. Historical data recorded in the Registry for 10 selected key variables were extracted and compared with the patients' individual medical records at the reporting hospitals as reference. The reviewers were blinded to the previously stored information. The intraclass correlation coefficient for continuous variables and Cohen's kappa for categorical variables were calculated.ResultsPrimary source data on 285 of the 300 women selected from Norwegian Female Incontinence Registry were successfully retrieved. The completeness of the registry has increased from 61% in 2008 to 99% in 2017. The national coverage has increased from 12 reporting departments in 1998 to all 38 public departments performing female incontinence surgery in 2017. Excellent accuracy was found for both continuous variables (intraclass correlation coefficient >0.94) and categorical variables (Cohen's kappa >0.86). No differences in data accuracy were found comparing high‐volume hospitals with low‐volume hospitals, or when comparing data accuracy over time.ConclusionsThe Norwegian Female Incontinence Registry is a reliable tool for quality assessment of incontinence surgery and research. The registry completeness has improved over time and now contains data on nearly all women undergoing incontinence surgery in Norway.

Published: July 2020

AbstractAimTo evaluate the relationship between clinical assessment of infant colour and oxygen saturation at birth in a low‐resource setting.MethodsClassification of infant colour (cyanotic, pink or unclear) by midwives was compared to pulse‐oximeter data at 60‐90‐120‐300 seconds after birth in 60 neonates.ResultsOverall, oxygen saturation increased over time (P < .0001) and was different according to infant colour (P < .0001). Median oxygen saturation in pink infants was 87% at 60 seconds (n = 1), 90% (IQR 83‐91) at 90 seconds (n = 5), 86% (IQR 81‐94) at 120 seconds (n = 11) and 93% (IQR 90‐96) at 300 seconds (n = 20). Median oxygen saturation in cyanotic infants was 60% (IQR 45‐70) at 60 seconds (n = 52), 64% (IQR 52‐69) at 90 seconds (n = 42), 63% (IQR 56‐68) at 120 seconds (n = 35) and 66% (IQR 62‐74) at 300 seconds (n = 22). Median oxygen saturation in unclear‐coloured infants was 57% (IQR 56‐60) at 60 seconds (n = 7), 78% (IQR 71‐81) at 90 seconds (n = 13), 81% (IQR 79‐88) at 120 seconds (n = 14) and 80% (IQR 76‐84) at 300 seconds (n = 18). The proportion of infants with unclear colour ranged from 12% to 30%.ConclusionThe variability of oxygen saturation among pink and cyanotic infants, and the substantial proportion of unclear infant colour, suggest the possible benefit of the availability of pulse oximetry in low‐resource settings.

ObjectivesTo assess the safety and feasibility of early single‐dose mitomycin C (MMC) bladder instillation after robot‐assisted radical nephroureterectomy (RARNU) at a tertiary kidney cancer centre. RARNU with bladder cuff excision and subsequent MMC bladder instillation to reduce recurrence risk is the ‘gold standard’ for high‐risk upper urinary tract urothelial carcinoma (UUTUC). We adapted a RARNU technique with precise distal ureteric dissection, bladder cuff excision and watertight bladder closure.Patients and MethodsWe retrospectively reviewed all patients undergoing RARNU for UUTUC at our centre performed as a standardised transperitoneal procedure comprising of: bladder cuff excision, two‐layer watertight closure and intraoperative bladder leak test; without re‐docking/re‐positioning of the robotic surgical system. Patient demographics, the timing of MMC instillation, adverse events (surgical and potentially MMC‐related) and length of stay (LOS) were assessed according to the Clavien–Dindo classification.ResultsA total of 69 patients underwent a RARNU with instillation of MMC. The median (interquartile range [IQR]) age was 70 (62–78) years. The median (IQR) day of MMC instillation was 2 (1–3) days and the median (IQR) LOS was 2 (2–4) days, with urethral catheter removal on day of discharge in all cases. Only Grade I Clavien–Dindo complications occurred in seven patients (10%); five had ileus, one a wound infection and one a self‐limiting delirium, all managed conservatively. No adverse events potentially related to MMC instillation were noted within 30 days postoperatively.ConclusionThe use of intravesical MMC instillation given in the immediate postoperative period appears feasible and safe in patients undergoing RARNU with intraoperative confirmation of a water‐tight closure ensuring early catheter‐free discharge, with no significant adverse events. The potential reduction in intravesical recurrence in patients receiving early MMC needs to be assessed with longitudinal follow‐up studies.

AbstractTirabrutinib is a second‐generation Bruton’s tyrosine kinase inhibitor with greater selectivity than ibrutinib. Here, we conducted a multicenter, phase II study of tirabrutinib in patients with treatment‐naïve (Cohort A) or with relapsed/refractory (Cohort B) Waldenström’s macroglobulinemia (WM). Patients were treated with tirabrutinib 480 mg once daily. The primary endpoint was major response rate (MRR; ≥ partial response). Secondary endpoints included overall response rate (ORR; ≥ minor response), time to major response (TTMR), progression‐free survival (PFS), overall survival (OS), and safety. In total, 27 patients (18 in Cohort A; 9 in Cohort B) were enrolled. The median age was 71 y, and the median serum immunoglobulin M level was 3600 mg/dL. Among the patients, 96.2% had the MYD88L265P mutation. MRR and ORR were 88.9% and 96.3%, respectively (Cohort A: MRR, 88.9%; ORR, 94.4%; Cohort B: MRR, 88.9%; ORR, 100%). Median TTMR was 1.87 mo. PFS and OS were not reached with a median follow‐up of 6.5 and 8.3 mo for Cohorts A and B, respectively. The most common adverse events (AEs) were rash (44.4%), neutropenia (25.9%), and leukopenia (22.2%), with most AEs classified as grade 1 or 2. Grade ≥ 3 AEs included neutropenia (11.1%), lymphopenia (11.1%), and leukopenia (7.4%). No grade 5 AEs were noted. All bleeding events were grade 1; none were associated with drug‐related atrial fibrillation or hypertension. Although the follow‐up duration was relatively short, the study met the primary endpoint. Therefore, tirabrutinib monotherapy is considered to be highly effective for both untreated and relapsed/refractory WM with a manageable safety profile. (JapicCTI‐173646).
Time and Singular Causation—A Computational Model
Authors: Stephan Simon , Mayrhofer Ralf , Waldmann Michael R. 
Published: July 2020

AbstractCausal queries about singular cases, which inquire whether specific events were causally connected, are prevalent in daily life and important in professional disciplines such as the law, medicine, or engineering. Because causal links cannot be directly observed, singular causation judgments require an assessment of whether a co‐occurrence of two events c and e was causal or simply coincidental. How can this decision be made? Building on previous work by Cheng and Novick (2005) and Stephan and Waldmann (2018), we propose a computational model that combines information about the causal strengths of the potential causes with information about their temporal relations to derive answers to singular causation queries. The relative causal strengths of the potential cause factors are relevant because weak causes are more likely to fail to generate effects than strong causes. But even a strong cause factor does not necessarily need to be causal in a singular case because it could have been preempted by an alternative cause. We here show how information about causal strength and about two different temporal parameters, the potential causes' onset times and their causal latencies, can be formalized and integrated into a computational account of singular causation. Four experiments are presented in which we tested the validity of the model. The results showed that people integrate the different types of information as predicted by the new model.
