Regional high‐T/low‐P metamorphism of the Kemum Basement High, Bird’s Head, West Papua, Indonesia
Authors: Jost Benjamin M. , Webb Max , White Lloyd T. , Tiranda Herwin 
Published: December 2020

AbstractThe northernmost part of the Australian continent is exposed in a basement high in the Bird's Head Peninsula at the NW tip of New Guinea. This basement consists of Silurian–Devonian turbidites that were regionally metamorphosed in the lower greenschist facies. Along its eastern margin, the basement high is intruded by numerous granitoid bodies and records a second, higher‐grade metamorphic overprint. We present the first detailed study of metamorphic rocks from this eastern part of the basement high, supported by field and petrographic observations, bulk rock and mineral chemistry, and phase equilibria modelling. Lower‐grade basement rocks include chlorite‐mica schists, slates, silt‐, and sandstones, which give way to andalusite‐ and cordierite‐bearing pelites and psammites, interspersed with layers of quartzite. The dominating pelitic phase assemblage is biotite+white mica±andalusite±cordierite+plagioclase+quartz+ilmenite; incipient sillimanite (fibrolite) is present in some rocks and replaces andalusite in baked margins around the numerous dykes and sills. Other rock types include metasedimentary migmatites, metacarbonates and calcsilicate concretions, rare metavolcanics, and kyanite‐bearing segregation veins. Metamorphism is of regional extent and often unrelated to granitoid intrusions. Our observations support the previous notion of an increase in peak metamorphic temperature from west to east. Microstructural relations suggest two phases of metamorphism, which are tentatively correlated with two phases of magmatic activity in the Devonian–Carboniferous and the Permian–Triassic. Based on petrographic observations and phase equilibria modelling, we propose that during the Permian–Triassic, metamorphism proceeded under high temperature/low pressure (HT/LP) or Abukuma‐type conditions along a narrow, counter‐clockwise P–T–t path with peak metamorphic conditions of the amphibolite facies (~520–650°C and ~2–4 kbar), potentially in an active continental margin setting. While much less evidence is available, similar metamorphic conditions are proposed for the Devonian–Carboniferous metamorphic event.

AbstractThe northwest Atlantic subspecies of gray seal (Halicheorus grypus grypus) has been increasing for more than a half century and has reestablished breeding colonies in Canadian and US waters. In 2016, visual, oblique, and vertical large‐format digital photographic surveys were conducted at all known breeding colonies in the northwest Atlantic. Total pup production in the northwest Atlantic was estimated to be 109,000 (SE= 17,500) pups. At 87,500 (SE= 15,100) pups, Sable Island accounts for 80% of total pup production. Regional differences in pup production trends are evident. Pup production in the Gulf of St. Lawrence and along the eastern shore of Nova Scotia has been relatively stable. Since 2004, the rate of increase in pup production at Sable Island has slowed to about 5%–7% per year, while the newer colonies in southwest Nova Scotia and the northeastern United States are increasing rapidly. In 2016, the Muskeget Island (MA) breeding colony produced 3,900 (SE= 200) pups, making it the third largest breeding colony in the northwest Atlantic. This southward shift in production may reflect climate‐mediated changes in population growth as well as reestablishment of colonies throughout the former range associated with increased protection.

Published: December 2020

AbstractObjectiveTo compare the efficacy of vacuum‐formed and banded space maintainers for deciduous second molar space maintenance during the mixed dentition.Setting and Sample PopulationThe study sample comprised thirty children in the mixed dentition (age range, 5.9 to 9.8 years) with early loss of at least one deciduous second molar.MethodsThis was a parallel‐group, randomized, active‐controlled clinical trial. Patients were randomly allocated to space maintenance performed with vacuum‐formed or banded space maintainers with a 1:1 allocation ratio. The main outcome was any change in mesiodistal width of the extraction space. Secondary outcomes included the lingual rolling or axial rotation of the permanent first molar adjacent to the extraction site and extrusion of the antagonist tooth. Dental casts were obtained before appliance installation (T0), after 3 months (T1) and after 6 months (T2). Digital dental casts were measured using Dolphin 3D software. Chi‐square, t test or Mann‐Whitney and ANOVA or Friedman test were used for intra‐ and intergroup comparisons (P < .05).ResultsBaseline characteristics were similar between groups except for chronological age. Statistically, but not clinically significant space loss (mean, 0.32 mm; SD, ± 0.39) occurred with the vacuum‐formed space maintainer only at the first trimester (T0‐T1). Lingual rolling and axial rotation of the first permanent molar were not significant, as well as extrusion of the antagonist tooth.ConclusionsThe results of this study suggested that both tested devices were effective in maintaining space after early extraction of the deciduous second molar over a period of 6 months.

SummaryBackgroundChronic actinic dermatitis (CAD) is a photoallergic skin disease with abnormal hyperplasia. At present, the mechanism of abnormal proliferation is not clear.ObjectiveTo explore possible mechanism of CAD proliferative lesions.MethodsImmunohistochemistry (IHC) assay and small RNA sequencing were carried out. Quantitative real‐time PCR (qRT‐PCR) analysis was performed to evaluate expression levels of hsa‐miR‐221‐3p and FOS. The interaction between hsa‐miR‐221‐3p and FOS was identified by dual‐luciferase reporter assay. Expression of hsa‐miR‐221‐3p also was detected by qRT‐PCR after UVB irradiation. Influences of hsa‐miR‐221‐3p and FOS on cell viability and apoptosis were assessed through a series of functional experiments and rescue experiments. Western blot analysis was used to detect protein expression of fos, Bax, Bcl‐xL, and caspase‐3.ResultsPatients with CAD had marked epidermal hyperplasia. The expression of hsa‐miR‐221‐3p was up‐regulated in CAD while FOS was significantly down‐regulated. Dual‐luciferase reporter assay confirmed that hsa‐miR‐221‐3p targeted FOS 3'UTR. Hsa‐miR‐221‐3p induced by UVB ranged from 0 to 30 mJ. Moreover, hsa‐miR‐221‐3p overexpression or FOS knockdown promoted cell proliferation and reduced cell apoptosis. Western blot showed that hsa‐miR‐221‐3p negatively regulated fos, which regulated Bcl‐xL/Bax. Cell proliferation caused by hsa‐miR‐221‐3p overexpression or FOS knockdown could be reversed by Bcl‐xL inhibitor.ConclusionHsa‐miR‐221‐3p induced by UVB targeted FOS 3′UTR, which played an important role in regulating proliferation and apoptosis of keratinocytes via Bcl‐xL/Bax pathway; this may provide a new insight for CAD proliferative lesions.
Savor the moment: Willful increase in positive emotion and the persistence of this effect across time
Authors: Wilson Kayla A. , MacNamara Annmarie 
Published: December 2020

AbstractSavoring is an emotion regulation technique that aims to increase, sustain, and deepen positive emotion. It has been incorporated into several novel, “positive affect” interventions for anxiety, depression, and chronic pain, but has not been studied in a laboratory setting. As such, it is unknown whether savoring can modulate subjective and neural correlates of emotion‐processing and whether savoring might exert a persistent effect on stimulus processing (i.e., modulating response at subsequent encounter). Here, 49 participants savored or viewed positive and neutral pictures, before seeing the same pictures again approximately 20 min later without instructions to savor (or view) pictures. Subjective valence and arousal ratings and the picture‐elicited late positive potential (LPP) were assessed during both tasks. Results showed that savoring increased participant ratings of picture pleasantness and arousal as well as a picture‐elicited LPP. Moreover, pictures that had previously been savored continued to elicit higher ratings during the subsequent picture viewing task. A larger LPP was observed for previously savored positive and neutral pictures during an early portion of picture viewing; later on during picture viewing, this effect was limited to positive pictures only (i.e., it was not evident for neutral pictures). Results validate savoring as an effective and durable means of increasing positive emotion and are discussed in the context of a broader emotion regulation literature, which has primarily examined the downregulation of negative picture processing.
Closing the Gap or Widening the Divide: The Impacts of Technology‐Enabled Coproduction on Equity in Public Service Delivery
Authors: Xu Corey Kewei , Tang Tian 
Published: December 2020

AbstractThis article investigates how 311 systems affect distributional equity in public service delivery. Many local governments in the United States have adopted interactive 311 platforms to engage citizens in coproduction. Using a novel household‐level data set on 311 service requests and power service restoration in the City of Tallahassee, Florida, after Hurricane Michael in 2018, the authors examine possible disparities between racial minority groups and nonminorities in making power service restoration requests via 311. The article further analyzes how coproduction participation through 311 affects distributional equity in power restoration. The findings show that minority groups are more likely to utilize these smart technologies to submit requests for essential services after disasters, as they may have greater needs but less political capital to reach out to the government. Their utilization of e‐governance technologies has helped them gain more attention from the government, which narrows the equity gap in service delivery.
The silence of the donkeys: Sensorial entanglements between people and animals at Willowra and beyond
Authors: Vaarzon‐Morel Petronella 
Published: December 2020

AbstractAn indelible memory of visitors to Willowra Aboriginal community in Central Australia is the sound of donkeys braying as they roam the village in search of sustenance and are chased by barking dogs. While Warlpiri people view donkeys as an integral part of their sonic landscape, outsiders typically perceive the animals as a noisy, land‐management ‘pest’ and want them removed. Recently, the arrival of a stranger in a truck towing a donkey trailer provoked concerned discussion. Talk intensified when, for a few days, the donkeys disappeared, and the silence of the donkeys echoed throughout the community. Tracing emergent social relations and mimetic connections that entangle donkeys and people in the Willowra region, this paper explores why donkeys matter to local Warlpiri, sensorially and otherwise. I contrast Warlpiri coexistence with donkeys to the treatment of donkeys by conservationists as feral animal and by capitalists as commodity. Linking the silence of donkeys at Willowra to the global trade in ejiao, a glue made from donkey hides used in Chinese medicine and cosmetics, I engage with Michael Taussig's (2019) ‘The cry of the burro [donkey]’ to examine differing senses of being and predicaments that the sound of donkeys evoke cross‐culturally. I conclude with a call to listen differently to other‐than‐human beings when considering multispecies assemblages. Attending to the sonic range of donkeys as an expression of their agency, I suggest that we learn from Warlpiri and heed the cries of donkeys and their global silencing if we are to ensure our mutual survival.
Implementation of VRML/Java Web-Based Animation and Communications for the Next Generation Inspection System (NGIS) Real-Time Controller
Authors: Shackleford William , Stouffer Keith 
Published: December 2020

Abstract
The Next Generation Inspection System (NGIS) project is a testbed that consists of a Cordax Coordinate Measuring Machine (CMM), advanced sensors, and the National Institute of Standards and Technology (NIST) Real-Time Control System (RCS) open architecture controller. The RCS controller permits real-time processing of sensor data for feedback control of the inspection probe. The open architecture controller permits external access to internal data, such as the current position of the probe. A remote access web site was developed to access this data to drive a Virtual Reality Modeling Language (VRML) * model of the Cordax CMM. The remote access web site contains a client-controlled pan/tilt/zoom camera which sends video to the client as well as the VRML 3D model of the CMM that is controlled by the NGIS controller located at NIST. This remote access web site allows a client to monitor a remote inspection with a PC and an internet connection.
XML Based Markup Languages for Knowledge Management in Manufacturing Companies
Authors: Veeramani Dharmaraj , Garikapati Ramarao 
Published: December 2020

Abstract
The manufacturing industry is facing many new challenges including redefined customer expectations in the E-Commerce era. The consumer is now better informed, more demanding and has higher expectations in terms of product features, product performance and service. To respond to these expectations companies are seeking to leverage the collective experience of the organization and the consequent knowledge gained to deliver improved performance in product and service. However, some fundamental issues pertaining to formal and unambiguous definition of terms and semantics of the information to be stored and retrieved need to be addressed in the manufacturing industry to fully leverage Intranet enabled knowledge management. The formalization of such unambiguous vocabularies can be achieved through the construction of Industry Specific Markup Languages (ISMLs). In this paper, we present XML based ISMLs, Machining Markup Language (MML) and Foundry Markup Language (FML) for the machining and foundry industries respectively and illustrate proof-of-concept knowledge management applications or TOMEs (Treasury for manufacturing Experience) that use the ISMLs as the underlying data models.
Mapping the Product Development Process to Information Technology Solutions Through Use Models
Authors: Whitney Daniel E. , Patil Samir 
Published: December 2020

Abstract
Product development, especially the design of large complex systems, is a special type of business process. What makes it special is the highly coupled nature of design decisions and the large size of product development teams. It is not unusual to have several hundred multi-disciplinary members taking millions of design decisions over the life of the project. From the Information Technology (IT) perspective, the special nature of design presents a challenge of coordinating the interdependent tasks of the team and integrating them. This paper explores the role of IT, specifically software tools, in improving the product development process through a framework that better represents and captures design knowledge. In order to overcome the limitations of the current implementations, the concept of “Use models” is developed. A use model consists of the methods, tools, and a map of the design process. This map is in the form of a design structure matrix (DSM) that represents tasks and relationship knowledge at a system level. By combining a detailed process view with tools and methods, the Use model creates a better IT representation of the product development process.
Product Model Definition Support for Knowledge Aided Engineering Applications Development
Authors: Ferruccio Mandorli , Monica Bordegoni 
Published: December 2020

Abstract
This paper addresses applications developed for supporting design/production activities that are tailored on a specific product. Currently, these applications are developed coding the engineer’s knowledge captured by the system developer into the product model. Minimizing the programming skill required in current systems for knowledge capturing would allow the designers themselves to directly insert knowledge into the system. In order to allow that, we see two ways: providing “design by example” systems, or providing appropriate graphical user interfaces for the systems. The objective of this work is to demonstrate that visual user interfaces can be used as the key to integrate and customize knowledge aided engineering (KAE) applications.
In order to demonstrate this idea we have developed a prototype of an interactive visual interface integrated within a KAE system. The approach has proved to be efficient for the development of product dependent systems and for engineers’ knowledge capture, in respect to systems based on programming languages.
A Fuzzy-Based Optimal Delivery Scheduling Approach
Authors: Wang H. , Xue D. , Norrie D. H. 
Published: December 2020

Abstract
A fuzzy-based optimal delivery scheduling approach is introduced in this research. In this approach, optimal delivery scheduling is conducted at three different levels considering (1) one driver and one load, (2) one driver and multiple loads, and, (3) multiple drivers and multiple loads. Fuzzy-based clustering methods are employed to classify delivery tasks into driver groups, load groups, and location groups. The optimal sequence and timing parameters of the delivery tasks are identified using the fuzzy-based clustering results and state-space search. The intelligent optimal delivery scheduling system was implemented using Smalltalk.
Modeling Concurrent Product and Process Design Using a Game Theoretic Team Approach
Authors: Chen Li , Li Simon 
Published: December 2020

Abstract
A satisfaction-driven game theoretic approach is developed with application to team-based concurrent product and process design (CPPD). This team approach for CPPD is based upon optimization formalism in which the design team is responsible to optimize overall product functionality (or performance) and the manufacture team pursues to minimize total manufacturing cost. This dual-team model characterizes the respective aspects of product design and process design. In particular, the preference of each team against a design configuration is characterized through the application of fuzzy set theory, whereby the method of Design for Satisfaction (DfS) can be applied to seek the most favorite design that best fulfills the team goal. Based on the strategic team paradigms derived from game theory, fuzzy set operators are used to aggregate satisfaction metrics of two teams. As a result, three team design models plus related algorithms are developed to reveal typical team interactions in the context of design computations. An illustrative example is worked out to demonstrate the satisfaction-driven team design models.
Exploring the Effectiveness of Various Patterns in an Extended Pattern Search Layout Algorithm
Authors: Yin Su , Cagan Jonathan 
Published: December 2020

Abstract
Automated synthesis of product layout has the potential of substantially reducing design cycle time while allowing for quick check of interference, clearance, scale and fit prior to the building of physical prototypes. The search for optimal positions and orientations of parts in the layout typically requires a huge number of iterations. An extended pattern search layout algorithm based on coordinate search was introduced in an earlier paper and shown one-to-two orders of magnitude improvement in speed over a robust simulated annealing-based layout algorithm. Coordinate search is a simple and straightforward way of implementing the pattern search method in the layout problem. However, it is not taking advantage of the wide variety of heuristics admissible in pattern search methods for identifying promising search directions. By introducing various search patterns and exploring their effectiveness in the layout problem, we will address the question of whether complex tactics can do better than the basic coordinate pattern search. We present in this paper four different heuristics for generating pattern directions in the extended pattern search layout algorithm: the conjugate direction method, the modified gradient method, the rank ordering method, and the simplex method. These heuristics are utilized to identify promising search directions and update the set of pattern directions used in the algorithm over iterations. The performance of the different heuristics is compared to that of the basic coordinate pattern search layout approach.
A Most Probable Point Based Method for Uncertainty Analysis
Authors: Du Xiaoping , Chen Wei 
Published: December 2020

Abstract
Uncertainty is inevitable at every stage of the life cycle development of a product. To make use of probabilistic information and to make reliable decisions by incorporating decision maker’s risk attitude under uncertainty, methods for propagating the effect of uncertainty are therefore needed. When designing complex systems, the efficiency of methods for uncertainty analysis becomes critical. In this paper, a most probable point (MPP) based uncertainty analysis (MPPUA) method is proposed. The concept of the MPP is utilized to generate the cumulative distribution function (CDF) of a system output by evaluating the probability estimates at a serial of limit states. To improve the efficiency of locating the MPP, a novel MPP search algorithm is presented that employs a set of searching strategies, including evaluating derivatives to direct a search, tracing the MPP locus, and predicting the initial point for MPP search. A mathematical example and the Pratt & Whitney (PW) engine design are used to verify the effectiveness of the proposed method. With the MPPUA method, the probabilistic distribution of a system output can be generated across the whole range of its performance.
Topology Optimization of Structures With Geometrical Nonlinearities
Authors: Luo Jian Hui , Gea Hae Chang 
Published: December 2020

Abstract
In this paper, the stiffness optimization problem is investigated for structures with geometrical nonlinearities. The mean compliance of the structure is chosen as the objective function and its sensitivities are derived using the adjoint method. The optimal problem is formulated using a microstructure-based design domain method and is solved iteratively by a sequential convex approximation method. Three numerical examples are presented to show the applications of the proposed method and the results demonstrate that the geometrically nonlinear finite element analysis is indispensable to the optimization process of large displacement structures.
