Recurrent neural networks with long term temporal dependencies in machine tool wear diagnosis and prognosis
Authors: Zhang Jianlei , Zeng Yukun , Starly Binil 
Published: March 2021

AbstractData-driven approaches for machine tool wear diagnosis and prognosis are gaining attention in the past few years. The goal of our study is to advance the adaptability, flexibility, prediction performance, and prediction horizon for online monitoring and prediction. This paper proposes the use of a recent deep learning method, based on Gated Recurrent Neural Network architecture, including Long Short Term Memory (LSTM), which try to captures long-term dependencies than regular Recurrent Neural Network method for modeling sequential data, and also the mechanism to realize the online diagnosis and prognosis and remaining useful life (RUL) prediction with indirect measurement collected during the manufacturing process. Existing models are usually tool-specific and can hardly be generalized to other scenarios such as for different tools or operating environments. Different from current methods, the proposed model requires no prior knowledge about the system and thus can be generalized to different scenarios and machine tools. With inherent memory units, the proposed model can also capture long-term dependencies while learning from sequential data such as those collected by condition monitoring sensors, which means it can be accommodated to machine tools with varying life and increase the prediction performance. To prove the validity of the proposed approach, we conducted multiple experiments on a milling machine cutting tool and applied the model for online diagnosis and RUL prediction. Without loss of generality, we incorporate a system transition function and system observation function into the neural net and trained it with signal data from a minimally intrusive vibration sensor. The experiment results showed that our LSTM-based model achieved the best overall accuracy among other methods, with a minimal Mean Square Error (MSE) for tool wear prediction and RUL prediction respectively.
Cultural values predict national COVID-19 death rates
Authors: Ruck Damian J. , Borycz Joshua , Bentley R. Alexander 
Published: March 2021

AbstractNational responses to a pandemic require populations to comply through personal behaviors that occur in a cultural context. Here we show that aggregated cultural values of nations, derived from World Values Survey data, have been at least as important as top-down government actions in predicting the impact of COVID-19. At the population level, the cultural factor of cosmopolitanism, together with obesity, predict higher numbers of deaths in the first two months of COVID-19 on the scale of nations. At the state level, the complementary variables of government efficiency and public trust in institutions predict lower death numbers. The difference in effect between individual beliefs and behaviors, versus state-level actions, suggests that open cosmopolitan societies may face greater challenges in limiting a future pandemic or other event requiring a coordinated national response among the population. More generally, mass cultural values should be considered in crisis preparations.
A Circular Economy: Where Will It Take Us?
Authors: Hart Jim , Pomponi Francesco 
Published: March 2021

AbstractThe avalanche of environmental challenges, from local to global and back, has prompted responses at all levels from personal to inter-governmental. The results of these responses have fallen in the range between useful and counterproductive, with many examples on each side, but the scale of the overall challenge continues to escalate. Moving towards a zero-carbon global economy through absolute reductions in fossil fuel usage is a sure way of mitigating climate change, and a range of environmental, social and economic benefits would follow. The case for a Circular Economy (CE), however, is less clear. Whilst some CE initiatives may lead to the decoupling of economic growth from resource extraction, this does not necessarily equate to reducing the rate of extraction. Thus, the contribution of CE to the achievement of environmental objectives globally cannot be taken for granted. In terms of social impact, the best that can be said is that CE might be neutral. Technologies that promote the ‘sharing economy’ for instance, often suggested as a crucial CE strategy, create opportunities for individual wealth accumulation, but are also a route to the gig economy and the casualisation of labour. CE is arguably a business imperative, but definitive evidence to support the idea of a circular economy that meets social and environmental goals needs development.

Published: March 2021

AbstractThe devastating impacts that bio-degradable products such as plastic bags are having on human health, wildlife, and the environment is enormous, especially single-use once. Single-use plastics are non-biodegradable products and does not undergo biological decomposition nor degenerate. This review examines various government regulations targeted at changing behaviour against plastic bags consumption and their effectiveness. Following a rigorous search in 13 databases, including PubMed, Science Direct, Springer Nature, etc. only 17 peer-reviewed journal articles that are published between 2000 and 2019 and met the inclusion criteria were included in the study. Each study’s methodological quality was assessed using the GRADE system, and data were extracted using a uniquely designed form. The results revealed that regulations based solely on the thickness of plastic bags does not reduce plastic bags consumption. However, regulations focused on banning ‘single-use’ plastic bag usage, imposing higher taxes and levies on consumers, significantly reduce plastic bags consumption. Overall, the latter is considered the most effective. Also, the results show that attitude, perception and behaviour change toward bio-degradable products or climate-friendly behaviour can be significantly influenced by public policy or regulations. Although the behaviour seems short-lived in some countries, therefore further studies need to probe on why. Also, the absence of a national regulatory strategy in North America reduced the inclusion of studies from the region, hence need for more research focusing on sub-national regulations.

Published: March 2021

AbstractThe current study was assumed to identify the novel nematicidal activity of chloroform and methanol (50:50, v/v) seed extracts of eight medicinally important plants viz. Abrus precatorius Linn., Amaranthus virdis Linn., Bunium persicum Boiss., Dioscorea deltoidea Wall. Ex Griseb., Teraxacum officinale Weber., Malva neglecta Wall., Podophylum hexandrum Royle and Robina pseudoacacia Linn. using the root-knot nematode Meloidogyne incognita in in vitro and greenhouse experiments. At 72 h exposure, the extracts were found to be highly nematostatic, where nematodes were completely paralyzed at 12 and 48 h of exposure. However, dominant mortality was observed by T. officinale 93.67% and B. persicum 89.66% seed extracts at 72 h. In greenhouse method, extracts of T. officinale and B. persicum extracts were found to be most potent in reducing number of galls (1.76 and 2.37) and number of egg masses (0.06 and 2.18) respectively as compared to inoculated control. The root knot index of all extracts varied between 1–3 and egg mass index 0–3 as compared to control. This study suggested that seed extracts of these plants can be used for the management of M. incognita and could be used in replacement of synthetic nematicides upon further isolation and purification of bioactive substance responsible for nematicidal activity.

Published: March 2021

BACKGROUND:
The Predictive Optimal Trees in Emergency Surgery Risk (POTTER) tool is an artificial intelligence-based calculator for the prediction of 30-day outcomes in patients undergoing emergency operations. In this study, we sought to assess the performance of POTTER in the emergency general surgery (EGS) population in particular.

METHODS:
All patients who underwent EGS in the 2017 American College of Surgeons NSQIP database were included. The performance of POTTER in predicting 30-day postoperative mortality, morbidity, and 18 specific complications was assessed using the c-statistic metric. As a subgroup analysis, the performance of POTTER in predicting the outcomes of patients undergoing emergency laparotomy was assessed.

RESULTS:
A total of 59,955 patients were included. Median age was 50 years and 51.3% were women. POTTER predicted mortality (c-statistic = 0.93) and morbidity (c-statistic = 0.83) extremely well. Among individual complications, POTTER had the highest performance in predicting septic shock (c-statistic = 0.93), respiratory failure requiring mechanical ventilation for 48 hours or longer (c-statistic = 0.92), and acute renal failure (c-statistic = 0.92). Among patients undergoing emergency laparotomy, the c-statistic performances of POTTER in predicting mortality and morbidity were 0.86 and 0.77, respectively.

CONCLUSIONS:
POTTER is an interpretable, accurate, and user-friendly predictor of 30-day outcomes in patients undergoing EGS. POTTER could prove useful for bedside counseling of patients and their families and for benchmarking of EGS care.
The UN Guiding Principles on Business and Human Rights: Implications for Corporate Social Responsibility Research
Authors: RASCHE Andreas , WADDOCK Sandra 
Published: March 2021

AbstractThis article presents a review of the literature on the United Nations Guiding Principles (UNGPs) for the purpose of situating the UNGPs in the voluntary corporate social responsibility (CSR) infrastructure. We identify four key themes that underlie the debate: (1) a critical assessment of the UNGPs, (2) their application to different sectors, (3) a discussion of how to embed key aspects of the UNGPs into national and regional contexts, and (4) reflections on the role of due diligence. We discuss these themes and outline some practical and theoretical take-away messages. Our review highlights some similarities and differences to the discussion of voluntary initiatives in the field of CSR, especially the UN Global Compact. Our discussion helps to understand how the UNGPs are situated in the voluntary institutional infrastructure for CSR. Finally, we show how the theoretical and practical discourse on the UNGPs can be further advanced.

ABSTRACT:Objective:To determine the demographic pattern of juvenile-onset parkinsonism (JP, <20 years), young-onset (YOPD, 20–40 years), and early onset (EOPD, 40–50 years) Parkinson’s disease (PD) in India.Materials and Methods:We conducted a 2-year, pan-India, multicenter collaborative study to analyze clinical patterns of JP, YOPD, and EOPD. All patients under follow-up of movement disorders specialists and meeting United Kingdom (UK) Brain Bank criteria for PD were included.Results:A total of 668 subjects (M:F 455:213) were recruited with a mean age at onset of 38.7 ± 8.1 years. The mean duration of symptoms at the time of study was 8 ± 6 years. Fifteen percent had a family history of PD and 13% had consanguinity. JP had the highest consanguinity rate (53%). YOPD and JP cases had a higher prevalence of consanguinity, dystonia, and gait and balance issues compared to those with EOPD. In relation to nonmotor symptoms, panic attacks and depression were more common in YOPD and sleep-related issues more common in EOPD subjects. Overall, dyskinesias were documented in 32.8%. YOPD subjects had a higher frequency of dyskinesia than EOPD subjects (39.9% vs. 25.5%), but they were first noted later in the disease course (5.7 vs. 4.4 years).Conclusion:This large cohort shows differing clinical patterns in JP, YOPD, and EOPD cases. We propose that cutoffs of <20, <40, and <50 years should preferably be used to define JP, YOPD, and EOPD.
Dystonia in Performing Artists: Beyond Focal Hand Dystonia
Authors: Ray Somdattaa , Pal Pramod K. 
Published: March 2021

ABSTRACT:Overuse of specific muscles in perfecting movements in performing arts makes an artist prone to many medical conditions. Musicians’ hand dystonia is focal task-specific dystonia (FTSD) of hand among musicians that has been extensively studied. However, embouchure, lower limbs, and laryngeal muscles can also be affected among musicians. Embouchure dystonia (ED) refers to dystonia of the perioral and facial muscles that occurs in musicians while playing embouchure instruments. It is essential to identify ED since the dystonia might become persistent and non-task-specific if the musician continues to play the instrument. Task-specific dystonia of lower limbs among musicians has been exclusively reported among drummers. The diagnosis rests on electromyogram (EMG) of the involved muscles during the task. Singer’s dystonia (SD) refers to task-specific laryngeal dystonia that occurs only while singing. The diagnosis of SD is based on laryngeal EMG and spectrographic analysis. Cortical hyperexcitability, loss of inhibition, and aberrant plasticity are central to the pathogenesis in both ED and musicians’ hand dystonia. The pathophysiological studies in SD are limited. This review aims to discuss the lesser known dystonias among performing artists – ED, FTSD of lower limb, and SD.
CHRONOLOGY OF THE MIS 3 MEGAFAUNA IN SOUTHEASTERN WEST SIBERIA AND THE POSSIBILITY OF LATE SURVIVAL OF THE KHOZARIAN STEPPE MAMMOTH (MAMMUTHUS TROGONTHERII CHOSARICUS)
Authors: Shpansky Andrei V , Kuzmin Yaroslav V 
Published: March 2021

ABSTRACTWe report a new series of radiocarbon (14C) dates on the MIS 3 megafauna for a previously poorly studied region of southeastern West Siberia. Some species, like woolly mammoth and woolly rhinoceros, and Pleistocene bison and horse, existed throughout the MIS 3 (ca. 29–59 ka cal BP); cave hyaena is dated to ca. 46,400 cal BP. The very late 14C dates on Khozarian steppe elephant (Mammuthus trogontherii chosaricus), ca. 45,100–45,400 cal BP, may indicate the survival of this species in Siberia up to MIS 3. More work is needed to confirm or reject this suggestion. Previously, Khozarian steppe elephant was known in Siberia only at the beginning of the Late Pleistocene (MIS 5e).
The Exclusionary Foundations of Embedded Liberalism
Authors: Goodman Sara Wallace , Pepinsky Thomas B. 
Published: March 2021

AbstractAnalyses of embedded liberalism have focused overwhelmingly on trade in goods and capital, to the exclusion of migration. We argue that much as capital controls were essential components of the embedded liberal compromise, so too were restrictions on the democratic and social rights of labor migrants. Generous welfare programs in labor-receiving countries thrived alongside inclusionary immigration policies, but this balanced arrangement was only tenable if migrants were politically excluded in their destination countries. That is, embedded liberalism abroad rested on exclusionary political foundations at home. In bringing together the IPE literature on the “globalization trilemma” with the comparative politics of citizenship, we provide a novel account of how embedded liberalism worked politically, with implications for current debates about the fate of the liberal order in a time of populist resurgence.
Remembering the 1977 Bread Riots in Suez: Fragments and Ghosts of Resistance
Authors: Soliman Nayera Abdelrahman 
Published: March 2021

AbstractMost of the existing literature on the 1977 Bread Riots focuses on the protests as an episode in larger national and international political and economic waves of change, either as the end of an era of political mobilization in Egypt, or the beginning of an era of anti-neoliberal struggles in the region and wider world. Moreover, most of the literature focuses on Cairo. Seeking to diverge from the trend even further, this article focuses on the memory of the 1977 uprising in the city of Suez, which it explores through the perspectives of leftist activists and others. It aims to understand how the people of Suez who witnessed and participated in the 1977 protests remember and interpret the event today, asking what memory of the uprising means politically on a local level. By exploring the memory of the 1977 protests in Suez, this article traces their effects on the lives of the selected interlocutors, and also on their political actions and interpretations. It follows three memory fragments of the 1977 protests in Suez from three different vantage points: the position of people who were members of political organizations before the protests; the traces of protests in Suez's streets; and the position of those who witnessed the protests from home.
Francis Bacon on Imperial and Colonial Warfare
Authors: Zeitlin Samuel Garrett 
Published: March 2021

AbstractThis article offers a textual and historical reconstruction of Francis Bacon's thought on imperial and colonial warfare. Bacon holds that conquest, acquisition of peoples and territory through force, followed by subjugation, confers a legal right and title. Imperial expansion is justified both by arguments concerning the interstate balance of power and by arguments related to internal order and stability. On Bacon's view, a successful state must be expansionist, for two key reasons: first, as long as its rivals are expansionist, a state must keep up and even try to outpace them, and, second, a surplus population will foment civil war unless this “surcharge of people” is farmed out to colonies. These arguments for imperial state expansion are held to justify both internal and external colonization and empire. Paradoxically, Bacon holds that the internally colonized may be treated with greater severity, as suppressed rebels, than the externally colonized, who are more fitly a subject of the ius gentium. Bacon holds that toleration offers both an imperial stratagem and a comparative justification for why English and British imperial expansion is more desirable than Spanish imperial expansion. The article concludes with reflections about how one might understand the place of imperial and colonial projects in Bacon's thought, contending that these projects are central to an understanding of Bacon's political aims and thought more broadly.
Transapical access for dilatation of a Melody valve in the mitral position using large balloons, in a small child: a case description with midterm follow-up and literature review
Authors: Kantzis M. , Shebani S. , Yong S. , Saeed I. 
Published: March 2021

AbstractThe surgical placement of the Melody®valve in the mitral position in infants and young children was first reported in 2012. Since then, there have only been a limited number of technically oriented reports describing catheter techniques to tackle valve-related issues such as valve adjustment for somatic growth or the management of haemodynamically significant paravalvar regurgitation. We present a case study where severe paravalvar leaks were tackled using a hybrid approach and large low-pressure balloons in a child who had previously undergone Melody® valve implantation in the mitral position. The technical outcome remains very good at 18 months follow-up and the patient remains symptom-free.
Comparison of semi-automated versus manual quantitative right ventricular assessment in tetralogy of Fallot

Published: March 2021

AbstractBackground:Tetralogy of Fallot is a congenital heart defect diagnosed in infancy. Assessment of right ventricular size and function is important for evaluation of patients with tetralogy of Fallot, but these quantitative measures are challenging by echocardiography. This study evaluates a semi-automated software (EchoInsight®, Epsilon Imaging) by comparing its measures to manual measures in children with tetralogy of Fallot.Methods:Echocardiographic measurements were performed using manual techniques and semi-automated software. Right ventricular measurements included end-diastolic and end-systolic area, fractional area change, chamber dimensions, and tricuspid annular plane systolic excursion. Reliability, correlation, and agreement between manual and semi-automated measures were assessed.Results:Echocardiograms for 46 patients were analysed. Intra- and inter-observer reliabilities for semi-automated measures were good with intraclass correlation coefficients all over 0.95 and 0.85, respectively. There was high correlation between manual and semi-automated methods for areas and dimensions (r = 0.91–0.98). Tricuspid annular plane systolic excursion measures and fractional area change also correlated, albeit less strongly. The semi-automated measurements of end-systolic and end-diastolic area were a 20 and 47% higher than manual methods, respectively.The semi-automated method yielded a relative 52% lower fractional area change compared to the manual method.Conclusions:The semi-automated software generates quantitative right ventricular measures in children with tetralogy of Fallot with good reliability and good correlation with manual methods for all measures, but with significant difference between manual and semi-automated techniques for area and functional measures. The specific right ventricular geometry in tetralogy of Fallot children may be why, compared to normal anatomy, greater differences were observed between the two techniques.
Cross‐Shock Electrostatic Potentials at Mars Inferred From MAVEN Measurements

Published: March 2021

AbstractA bow shock is generated by the interaction of the solar wind with the planetary global dipole field (e.g., Earth), or with (mainly) the planetary ionosphere (e.g., Mars). The cross‐shock potential has been well studied at Earth but not yet for Mars. We infer and approximate the peak in the frame invariant de Hoffmann‐Teller shock potential profile at Mars (ϕ) with data from the Mars Atmospheric and Volatile EvolutioN (MAVEN) mission. We find that ϕ and its ratio to the solar wind ram ion energy (Eram) vary similarly against solar zenith angle (SZA, a proxy for the angle between the solar wind flow and the shock normal) and magnetic latitudes. Our results also reveal no significant dependence of the shock potential on parameters such as the angle between the upstream interplanetary magnetic field (IMF) and the shock normal and plasma beta of upstream solar wind. There is a somewhat positive correlation with the magnetosonic Mach number and the magnetic amplification ratio across the shock. We also find a solar cycle effect on the shock location, closer to the planet near the solar minimum, as expected. Lastly, similarities and differences of cross‐shock potentials at Mars and Earth are discussed. Characterizing electron energization and high‐altitude ion loss at Mars is influenced by the bow shock and thereby the work here.
