Online Maintenance Prioritization Via Monte Carlo Tree Search and Case-Based Reasoning
Authors: Hoffman Michael , Song Eunhye , Brundage Michael , Kumara Soundar 
Published: January 2022

AbstractWhen maintenance resources in a manufacturing system are limited, a challenge arises in determining how to allocate these resources among multiple competing maintenance jobs. This work formulates an online prioritization problem to tackle this challenge using a Markov decision process (MDP) to model the system behavior and Monte Carlo tree search (MCTS) to seek optimal maintenance actions in various states of the system. Further, case-based reasoning (CBR) is adopted to retain and reuse search experience gathered from MCTS to reduce the computational effort needed over time and to improve decision-making efficiency. The proposed method results in increased system throughput when compared to existing methods of maintenance prioritization while also reducing the computation time needed to identify optimal maintenance actions as more information is gathered. This is especially beneficial in manufacturing settings where maintenance decisions must be made quickly to minimize the negative performance impact of machine downtime.

Abstract
Measuring the motions of human hand joints is often a challenge due to the high number of degrees-of-freedom. In this study, we proposed a hand tracking system utilizing action cameras and ArUco markers to continuously measure the rotation angles of hand joints during motion. Three methods were developed to estimate the joint rotation angles. The pos-based method transforms marker positions to a reference coordinate system and extracts a hand skeleton to identify the rotation angles. Similarly, the orient-x-based method calculates the rotation angles from the transformed x-orientations of the detected markers in the reference coordinate system. In contrast, the orient-mat-based method first identifies the rotation angles in each camera coordinate system using the detected orientations and then synthesizes the results regarding each joint. Experiment results indicated that the repeatability errors with one camera regarding different marker sizes were around 2.64–27.56 deg and 0.60–2.36 deg using the marker positions and orientations, respectively. With multiple cameras employed, the joint rotation angles measured by using the three methods were compared with that measured by a goniometer. Comparison results indicated that the results of using the orient-mat-based method are more stable and efficient and can describe more types of movements. The effectiveness of this method was further verified by capturing hand movements of several participants. Therefore, it is recommended for measuring joint rotation angles in practical setups.

Tertiary lymphoid structures in cancer
Tertiary lymphoid structures (TLSs) are lymphoid formations that are found in nonlymphoid tissues. TLS can develop in inflamed tissues and are associated with chronic inflammatory disorders, autoimmunity, and cancer. In the setting of tumors, TLSs facilitate the influx of immune cells into the tumor site and have therefore attracted interest as a means of improving anticancer immunity and favorable treatment response in patients. Schumacher and Thommen review the biology of TLSs and outline recent advances in TLS research. They discuss how TLSs are detected and defined, the mechanism(s) of formation in cancer, and the potential of targeting TLSs for therapeutic benefit. —PNK

Published: January 2022

BackgroundPrevious studies have suggested an association between vascular endothelial growth factor A (VEGFA) rs3025039 polymorphism and biliary atresia (BA). However, this conclusion is controversial and there is no published pooled evidence of this association.MethodsThis study was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The protocol was registered with PROSPERO (International Prospective Register of Systematic Reviews). A thorough search was performed on databases including PubMed, Embase, and Chinese Biomedical Database up to August 2020. This study included 846 cases of BA and 2821 controls concerningVEGFArs3025039 polymorphism. We selected relevant studies based on the following inclusion criteria: (1) the study design was case–control and cohort and (2) the patients carried standard clinical diagnoses of BA, etc. The exclusion criteria were as follows: (1) patients with other related diseases, (2) lack of requisite information and (3) duplicate data. The OR (odd ratio) and the corresponding 95% CI (confidence interval) were calculated to estimate the association.ResultsThis study onVEGFArs3025039 polymorphism in the Chinese population included 846 cases and 2821 controls. The results showed that there was no significant association between rs3025039 and susceptibility to BA under four genetic models. The results of the subgroup analysis were similar to the overall results.ConclusionsThis meta-analysis shows that rs3025039 was not associated with susceptibility to BA in the Chinese population. Further validation may entail additional research.PROSPERO registration numberCRD42020203812.

Published: January 2022

AbstractThe polynomial affine gravity is a model that is built up without the explicit use of a metric tensor field. In this article we reformulate the three-dimensional model and, given the decomposition of the affine connection, we analyse the consistently truncated sectors. Using the cosmological ansatz for the connection, we scan the cosmological solutions on the truncated sectors. We discuss the emergence of different kinds of metrics.
GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences
Authors: Wang Sai , Zhao Zhi-Chao 
Published: January 2022

AbstractTwo gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a scenario of primordial black hole binaries that are formed in the early Universe. The merger rate predicted by such a scenario could be consistent with the one estimated from LIGO and Virgo, even if primordial black holes constitute a fraction of cold dark matter. The required abundance of primordial black holes is compatible with the existing upper limits from microlensing, caustic crossing and cosmic microwave background observations.
Theoretical fabrication of subwavelength structures by surface plasmon interference based on complementary grating
Authors: Wang Xiangxian , Ren Yaqian , Jia Tianxu , Su Yingwen , Qi Yunping , Wen Xiaolei 
Published: January 2022

This paper presents a surface plasmon interference lithography technique based on the complementary grating, which comprises silicon gratings and complementary aluminum grating masks, for fabricating subwavelength structures. In this theoretical study, the optimal parameters of the complementary grating structure were determined using the reflectance spectrum. The optical field distributions of one- and two-dimensional subwavelength structures were obtained using the finite-difference time-domain method and rotation-related formulas. The results of numerical evaluations show that a one-dimensional periodic structure with a half-pitch resolution of 60.5 nm (approximately [Formula: see text]/6.7) can be fabricated. In addition, subwavelength structures can be diversified using different rotation methods to expose the photolithography samples, such as square dot arrays and quasi-hexagonal closely packed structures. The proposed method combines surface plasmon interference with sample rotation, thereby enabling fabrication of abundant subwavelength structures.
“Communist Muslims”
Authors: Klimentov Vassily A. 
Published: January 2022

Abstract
Soviet leaders sent troops into Afghanistan in December 1979 to support a friendly Marxist-Leninist regime in its conflict against a popular insurgency and help it build a new society. When the Soviet troops withdrew nine years later, they left behind a state that had none of the nominal characteristics of a Soviet-type Communist country. During the war, the People's Democratic Party of Afghanistan had discarded Marxism-Leninism and turned to Islam. This article examines how, with Moscow's support, the Afghan Communists Islamicized their discourse and policies as they tried to gain support from the population and co-opt insurgent fighters.
“The Voice of Your Wife”: Why an Ancient Interpreter Chose to Voice Eve with a Testament
Authors: Chapman Cynthia R. 
Published: January 2022

Abstract
Eve’s Testament (Greek Life of Adam and Eve 15–30) contains an expansive first-person retelling of the Eden narrative in which an elder Eve remembers her younger self calling to Adam “with a loud voice” and saying, “listen to me!” She then admits that when she opened her mouth, “the Devil was speaking,” and she was able to quickly persuade her husband to eat of the forbidden fruit. The unparalleled decision of an ancient author to voice the primordial woman with a testament builds exegetically on a textual problem in Gen 3:17 where YHWH Elohim punishes the man for “listening to the voice of his wife” when the woman never spoke to the man in Gen 2–3. Eve’s Testament provides the missing voice of Adam’s wife, and through it, we learn how the devil used her voice to get Adam “cast out of Paradise.”
The Role of UN Documentation in Shaping Narratives at the International Criminal Court and the Implications for the Rights of the Accused
Authors: Herzberg Anne 
Published: January 2022

Abstract
The International Criminal Court (icc) is an independent treaty-based international organisation acting in close cooperation with the United Nations (UN). To that end, organs of the Court have extensively relied on UN documentation in proceedings. These materials have been used to support grounds for the exercise of jurisdiction, demonstrate legal elements of crimes, and prove matters of fact. In recent practice, including in the situations of Palestine, Bangladesh/Myanmar, and Mali, UN materials have been used to establish legal and factual matters on the primary basis that they represent the ‘views of the international community’. This paper examines the ways in which Court organs rely on UN documentation in icc proceedings. It assesses the interplay of such information with rights of the accused. The paper concludes that in order to safeguard its credibility and the fairness of the proceedings, the Court should adopt specific guidelines relating to the evaluation of and admissibility of UN materials.
Technolegal Expulsions: Platform Food Delivery Workers and Work Regulations in Colombia
Authors: Sanchez Vargas Derly Yohanna , Maldonado Castañeda Oscar Javier , Hernández Mabel Rocío 
Published: January 2022

Abstract
Precariousness of the Colombian urban economy provides an ecosystem for the development and expansion of digital platforms, intersecting informal working relations with digital surveillance. Reconstructing legal obstacles to gaining recognition as legal and formal workers, it is argued that platforms have assembled a techno-legal network which translates discussions about workers’ rights into the less regulated arena of information and communication technologies. The role of ‘regulatory displacement’ is examined to analyse the evolution of digital platforms for food delivery workers. Drawing on a review of the regulation of it and labour, discussed in Congress in 2017–2018, we explore the regulatory expulsions that digital workers experience, analysing this information with a grounded theory approach, in which we have followed discursive patterns that emerge from legal documents. Addressing this strategic use of the law is key to understanding and overcoming obstacles that platform workers face in their attempts to organize in the Global South.
Platform Worker Organising at Deliveroo in the UK: From Wildcat Strikes to Building Power
Authors: Woodcock Jamie , Cant Callum 
Published: January 2022

Abstract
It has been five years since the first strikes of Deliveroo workers in London in 2016. Since then, workers have continued to organise. The campaigns have involved five different aspects: first, wildcat strike action; second, networks and internationalisation; third, union organising with the Independent Workers Union of Great Britain (iwgb); fourth, legal campaigning; and fifth, wider leverage campaigns. What is less understood so far is the different strengths and weaknesses of these aspects, and how they have contributed to the build of workers’ self-organisation and power at Deliveroo. This article explores the different aspects and considers the effectiveness of each. It concludes by considering what can be learned from these struggles for the understanding of platform work and trade union organising today.
Emerging Platform Work in the Context of the Regulatory Loophole (The Uber Fiasco in Hungary)

Published: January 2022

Abstract
Platform works are swiftly turning into a big, perhaps game-changing force in the labor market. From low-skilled, low-paid services (like passenger transport) to high-skilled, high-paying project-based labor (like developing artificial intelligence algorithms), digital platforms can handle a wide range of tasks. Our paper discusses the platform-based content, working conditions, employment status, and advocacy problems. Terminological and methodological problems are dealt with in-depth in the course of the literature review, together with the ‘gray areas’ of work and employment regulation. To examine some of the complex dynamics of this fast-evolving arena, we focus on the unsuccessful market entry of the digital platform company Uber in Hungary 2016 and the relationship to institutional-regulatory platform-based work standards. Dilemmas about the enforcement of labor law regarding platform-based work are also paid special attention to the study. Employing a digital workforce is a challenge not only for labor law regulation but also for stakeholder advocacy.
Coalescence and Secondary Ice Development in Cumulus Congestus Clouds
Authors: Lawson R. Paul , Bruintjes Roelof , Woods Sarah , Gurganus Colin 
Published: January 2022

AbstractUnderstanding ice development in cumulus congestus (CuCg) clouds, which are ubiquitous globally, is critical for improving our knowledge of cloud physics, precipitation and climate prediction models. Results presented here are representative of data collected in 1008 penetrations of moderate to strong updrafts in CuCg clouds by five research aircraft in six geographic locations. The results show that CuCg with warm (∼23°C) cloud-base temperatures, such as in tropical marine environments, experience a strong collision–coalescence process. Development of coalescence is also correlated with drop effective radius >∼12 to 14μm in diameter. Increasing the cloud-base drop concentration with diameters from 15 to 35μm and decreasing the drop concentration < 15μm appears to enhance coalescence. While the boundary layer aerosol population is not a determinate factor in development of coalescence in most tropical marine environments, its impact on coalescence is not yet fully determined. Some supercooled large drops generated via coalescence fracture when freezing, producing a secondary ice process (SIP) with production of copious small ice particles that naturally seed the cloud. The SIP produces an avalanche effect, freezing the majority of supercooled liquid water before fresh updrafts reach the −16°C level. Conversely, CuCg with cloud-base temperatures ≤ ∼8°C develop significant concentrations of ice particles at colder temperatures, so that small supercooled water drops are lofted to higher elevations before freezing. Recirculation of ice in downdrafts at the edges of updrafts appears to be the primary mechanism for development of precipitation in CuCg with colder cloud-base temperatures.Significance StatementCumulus congestus clouds occur globally and account for a significant amount of precipitation in the tropics. The physics underlying the warm rain process and development of ice in cumulus congestus clouds are fundamental to a better understanding of precipitation formation. The collected data show that the strength of collision–coalescence is strongly influenced by cloud-base temperature, and that millimeter-diameter supercooled cloud drops will form in convective clouds with base temperatures warmer than 20°C. When supercooled large drops form, there is a secondary ice process that rapidly freezes the large majority of supercooled cloud water before updrafts reach the −16°C level. Incorporating results from the observations will improve cloud-resolving and climate prediction models.

Published: January 2022

Objective To begin to understand how to prevent deep vein thrombosis (DVT) after an innovative operation termed intracorporeal laparoscopic reconstruction of detenial sigmoid neobladder, we explored the factors that influence DVT following surgery, with the aim of constructing a model for predicting DVT occurrence. Methods This retrospective study included 151 bladder cancer patients who underwent intracorporeal laparoscopic reconstruction of detenial sigmoid neobladder. Data describing general clinical characteristics and other common parameters were collected and analyzed. Thereafter, we generated model evaluation curves and finally cross-validated their extrapolations. Results Age and body mass index were risk factors for DVT, whereas postoperative use of hemostatic agents and postoperative passive muscle massage were significant protective factors. Model evaluation curves showed that the model had high accuracy and little bias. Cross-validation affirmed the accuracy of our model. Conclusion The prediction model constructed herein was highly accurate and had little bias; thus, it can be used to predict the likelihood of developing DVT after surgery.
Effects of ECAE process on the fatigue crack growth rate of copper metal
Authors: Rezaei Eslam , Abbasi Kaveh , Pourhamid Reza 
Published: January 2022

In this study, the effects of the number of passes performed by the Equal Channel Angular Extrusion as a severe plastic deformation process on copper metal's microstructure and mechanical properties, especially its resistance to fatigue crack growth, have been investigated. The experimental results show that as the number of processes passes increases, the copper metal grains become finer and as a result less stress is concentrated at the starting points of the fatigue fracture, which delays the fracture. For example, after performing 8 ECAE process passes, the threshold values of fatigue crack growth increases by 113.2% relative to the base metal. Moreover, as the grains become smaller, the number of grains and consequently the number of grain boundaries will increase and thus more obstacles will be placed in the way of crack growth. Also, the SEM images indicate that many fine and equiaxed dimples in processed copper become smaller as the number of passes increases. This shows that finer and more equiaxed grains will be obtained by repeating the ECAE process and thus repeating the occurrence of recrystallization. It was cleared that this process improves the mechanical properties of the copper other than the failure strain. However, by increasing the number of process passes, this problem can be significantly reduced. Highlights The fine grains considerably delay the fatigue fracture By ECAE process, the threshold value of fatigue crack growth increases by 113.2% All zones resulting from fatigue fracture are recognizable in fractured ECAE sample The SEM images indicate that a ductile failure has occurred in the tensile samples
PIK3CA Mutations in Diffuse Gliomas: An Update on Molecular Stratification, Prognosis, Recurrence, and Aggressiveness

Published: January 2022

Introduction: PIK3CA is one of the most mutated oncogenes in solid tumors. In breast cancer (ER-positive, HER2-negative), these events represent a predictive biomarker of response to alpelisib. In glioblastomas (GBM), PIK3CA mutations were described as early constitutive events. Here, we investigated PIK3CA mutational profile across glioma molecular subgroups and its relevance during glioma recurrence. Furthermore, PIK3CA mutations’ effect in PI3K pathway, prognosis, and response to therapy was also explored. Material and Methods: Exons 10 and 21 of PIK3CA mutations were evaluated in 394 gliomas and 19 glioma recurrences from Instituto Português de Oncologia Lisboa Francisco Gentil (IPOLFG) and compared with The Cancer Genome Atlas (TCGA) data. TIMER2.0 and NetMHCpan4.1 were used to assess the immune-microenvironment contribution. Results: PIK3CA mutations were identified among all glioma subgroups, although with no impact on their stratification or prognosis. In both cohorts (IPOLFG and TCGA), PIK3CA mutation frequencies in IDH-mutant and IDH-wild-type GBM were similar (IPOLFG: 9% and 3%; TCGA: 8% and 2%). These mutations were not mutually exclusive with PTEN deletion and EGFR amplification. Despite their reduced frequency, we discovered PIK3CA mutations were maintained during glioma recurrence regardless of administered therapies. The immune microenvironment might not contribute to this phenotype as PIK3CA mutations did not influence immune cell infiltration. Conclusions: Despite the absence of a predominant effect in glioma stratification, PIK3CA mutations were maintained during glioma recurrence, possibly contributing to glioma cell survival, representing promising therapeutic targets in recurrent glioma. Nevertheless, understanding the potential synergistic effects between PIK3CA mutations, PTEN deletion, and EGFR amplification is pivotal to targeted therapies’ efficiency.
