Published: July 2019

Background Aorto-esophageal fistulae (AEFs) are a rare but serious and life-threatening disease of the mediastinum. Especially, AEF in the presence of infected stent grafts, for example, after thoracic endovascular aortic repair (TEVAR) is only curable by a multistage interdisciplinary surgical approach. This study presents the results of our four-stage approach consisting of bridging TEVAR, esophagectomy, complete stent removal followed by total bovine tube aortic replacement (TBTAR), and finally esophageal reconstruction.
Methods A case series of four patients from our department receiving a four-stage treatment of AEF is presented in this study. Retrospective database analysis focusing on overall survival, duration of intensive care unit and total hospital stay until discharge, complications, surgical time frame, and completion of chosen surgical treatment course was performed.
Results Overall, four patients surgically treated for AEF since May 2015 were included. A 30-day mortality was 0%, and overall survival at 1 year was 75%. All patients survived more than 5 months and could be discharged after TEVAR and esophagectomy. TBTAR could be performed in two of four patients (50%). Esophageal reconstruction was completed in all patients. Average follow-up was 20.3 ± 1.7 months or until death.
Conclusion The acute management of AEF using this approach seems satisfactory, especially for reducing acute short-term mortality. Complete restoration of the circulatory system and digestive tract remains challenging and is associated with high morbidity. We support the application of bridging TEVAR with a staggered approach to further surgical treatment individually tailored to the patient.
Morphology and syntax in the Scandinavian vernaculars of Ovansiljan
Authors: Garbacz Piotr 
Published: July 2019

AbstractThe paper deals with the assumed correlation between morphological and syntactic phenomena, especially the one that has its roots in a parametric approach to syntax since (Chomsky 1981). Its main focus is on testing predictions presented in two works (Bobaljik and Thráinsson 1998andHolmberg 2010a). These papers connect verbal morphology with a clustering of syntactic phenomena in the Scandinavian languages and maintain that morphological evidence – in the form of ‘rich’ verbal agreement – signifies a positive setting of a parameter that in turn makes certain syntactic patterns possible. In the present paper it is shown how this relation works when tested on a group of Ovansiljan vernaculars (East Scandinavian non-standard varieties). Five of these vernaculars have retained verbal agreement in number and person, whereas two others have not. It turns out that the hypotheses encounter difficulties when faced with the Ovansiljan data.

Abstract
Bi-containing III-V semiconductors constitute an exciting class of metastable compounds with wide-ranging potential optoelectronic and electronic applications. However, the growth of III-V-Bi alloys requires group-III-rich growth conditions, which pose severe challenges for planar growth. In this work, we exploit the naturally-Ga-rich environment present inside the metallic droplet of a self-catalyzed GaAs nanowire (NW) to synthesize metastable GaAs/GaAs1−x

Published: July 2019

Abstract
With the advancement of semiconductor technology, the assembly process of semiconductor packaging is driving the devices to become smaller and smaller in size. One of the critical processes in backend assembly is the product’s singulation to separate bulk processed products into individual unit. Before the sawing process kick-off, saw blade preparation (blade dressing) has to be performed. Blade dressing is the process of sharpening the saw blade surface to expose the diamond grits to the blade surface that are covered by the blade bonding material (Nickel-based). Inappropriate blade preparation technique induces burn mark defect to semiconductor devices. This research presented the dressing process optimization on critical factors using Silicon carbide (SiC) as part of the effort to enhance the product quality. The 2k Full Factorial Design of Experiment (DOE) methodology, with consideration of three factors namely Blade Revolution Per Minute (RPM), Feedspeed and Dress Pass. The overall singulation process yields performance improvement by reducing the burn mark to < 0.1% with optimum saw blade preparation technique. Besides, the optimized process complementarily contributes to less kerf deformation and dressing wear.
A 3-Pixel Fuzzy Mask for Edge Detection
Authors: Seng N H , Samad Z , Nor N M 
Published: July 2019

Abstract
A new group of fuzzy masks is proposed in this study to perform edge detection of images. A group of 3-pixel masks is used to detect edges in four directions. The resulting images retain more edges and show better continuity of the edges compared to the ones produced by the conventional 3 x 3 fuzzy masks. This is accomplished more efficiently using fewer fuzzy rules. Furthermore, thinning functions incorporated yielded edges with good continuity and optimal thickness.

Published: July 2019

Abstract
This study focuses on the deformation of cross arms made from composite material under static loading. Two materials properties of fiberglass with are assigned to the cross arms model and it is subjected to a load at the one end of the cross arms. A bracing support is then installed, and the deformation and stress experienced by the cross arms are observed and compared with the case where no bracing support is used. The results obtained show that material B has lower deformation value, but experienced greater stress compared to material A. The bracing managed to reduce the total deformation by about 12% and 20% for material A and B respectively. The reduction of stresses experienced by the cross arms ranges from 4% to 30%.
A Collaborative Scheme with Vendor in Kaizen
Authors: Peterson A D , Chin J F 
Published: July 2019

Abstract
The paper investigates a novel collaborative Kaizen scheme that involves vendor as the volunteered countermeasure provider in exchange for a fair sharing in gain. The skeleton of the scheme is made up of Plan-Do-Check-Act (PDCA). In Plan, the required improvement is first assessed by the Kaizen team to gauge the need to bring in vendor. The proposal must be scrutinized and undergoes negotiations for acceptable terms to both parties, which ultimately helps to build a long-term partnership. The scheme is presented as a case study in an Original Equipment Manufacturer (OEM) where energy consumption and maintenance cost for workstation lighting system at the production were reduced through the implementation of countermeasure proposed by vendor. The implementation cost was fully borne by the vendor and in return, the vendor would be paid in amount equivalent to the saving on the energy bill for the next nine months.

Published: July 2019

Abstract
The Particle Swarm Optimization (PSO) is an optimization method that was modeled based on the social behavior of organisms, such as bird flocks or swarms of bees. It was initially applied for cases defined over continuous spaces, but it can also be modified to solve problems in discrete spaces. Such problems include scheduling problems, where the Job-shop Scheduling Problem (JSP) is among the hardest combinatorial optimization problems. Although the JSP is a discrete problem, the continuous version of PSO has been able to handle the problem through a suitable mapping. Subsequently, its modified model, namely the discrete PSO, has also been proposed to solve it. In this paper, the performance of continuous and discrete PSO in solving JSP are evaluated and compared. The benchmark tests used are FT06 and FT10 problems available in the OR-library, where the goal is to minimize the maximum completion time of all jobs, i.e. the makespan. The experimental results show that the discrete PSO outperforms the continuous PSO for both benchmark problems.

Abstract
Globalization has made industrial competition to become intensified and more stringent. As technology advances, traditional management is deemed insufficient to meet the needs of many companies in order to achieve their goals. The theory of constraints is considered to be a pertinent method to overcome the faced challenges. The theory is aimed to effectively manage constraints that prevent companies from achieving their goals. It is focused on enhancing system capacity constraints and minimizing inventory and operating costs to increase the profit by managing company’s resources efficiently. The purpose of this study is to apply the theory on a case study in a printing company to manage obstacles in an effective way by defining constraints that prevent the company from achieving its targets. Thus, it can increase the company’s profitability. Results show that there are capacity constraints on glue and laminating machine causing the company to solely produce 72.06% of the total demand. It is suggested that if the company adds one more laminating glue machine, an increasing profit as much as 22.33 % can be attained.

Published: July 2019

Abstract
Maintenance is an important issue that needs to be addressed during the design and manufacturing or building of a system. Both Total Productive Maintenance (TPM) and Reliability Centered Maintenance (RCM) have its own concepts and principles as a maintenance strategy to give impact to the performance and reliability of the system. Therefore, in this research, the TPM will be studied with RCM to show their relationship. Based on the conceptual analysis, the author will analyze publications from journals, books, and articles to find all related information, such as genealogy, definition, concepts, and principle, and implementation of both strategy. The conceptual method used is Näsi’s four elements of conceptual analysis and a questionnaire survey method which has been answered electronically to study the current maintenance strategies in the real industries and to relate it to TPM and RCM. The result of the study shows that TPM had started in 1970 while RCM started in the 1960s, but the foundation of TPM and RCM was started in 1950s with Breakdown Maintenance (BM). TPM is basically about elimination of faults through day-today activities involving the entire force work while the concept of RCM is to improve equipment reliability. The objective of TPM is to achieve zero breakdowns, zero defects, and zero accidents while TPM is to preserve the functions. Although both are using different tools but both are linked together through the Lean Tool and can increase product quality, equipment reliability, increase safety, and increase profit. From the survey result, most of the respondent comes from the companies that implementing traditional maintenance (PM and CM) rather than TPM and RCM. TPM mostly can be implemented in big plant industries while RCM can be applied in small or medium size plant.

Abstract
Eucalyptus plant is a plant producing an essential oil. It is beneficial oil for fabricating the cosmetic and aroma therapy. In consequence, a quality of the oil is very substantial to ensure the quality of product. One of factor affecting it is the degree of purity of the oil. In the interest of producing the high purity, a good harvesting technique should be considered particularly with a design of the chopping tool. Preliminary study was found that the quality and number of the oil are still not able to reach the target by using the existing tool. Thus this is significant to improve the tool which is more effective and safer. The purpose of this study is to redesign the ergonomic and innovative chopping tool. TRIZ used to determine the inventive principles for producing the specific solutions or design on basis a contradiction between improving and worsening features. Fuzzy linguistic concept is implemented to specify the design attribute that is vague. Result of this study finds four specifications of a purposed design. They are sharp with specifications thickness of the tool at the tip is 0.2 cm and the base is 0.37 cm, then strong with specifications the gilding is done for 2.63 minutes with 1216ºC temperature, and for durable is the use of “Per” Steel as the material, and for comfortability is the size of the handle that corresponds to the dimensions of the human hand namely the diameter of the handle is 3.25 cm, the length of the handle is 12 cm, the width of each contour of the fingers is 2 cm using silicon rubber material. Signed-rank test results in that the proposed design is valid specifically it is more comfortable, more powerful, sharper, and more durable by using the existing design.

Published: July 2019

Abstract
Most badminton lunge studies considered only the male players. No study has investigated the effect of gender on the badminton lunge movement. Past researches presented the statistical analysis approach on badminton lunge motion study. However, no study has classified lunge motion specifically by gender segregation. This paper investigates the gender effects in distinguishing the five lunge directions; center-forward (CF), left-forward (LF), right-forward (RF), left-lateral (L) and right-lateral (R) lunges using classification approach. The case study involved video captures of five-male and six-female university-level players lunging in the badminton 21-point singles. A total of 23 attributes of 10894 instances were extracted to classify lunges into CF, LF, RF, L and R lunges using 21 classification algorithms of the WEKA tool. Lunge direction classifications were performed on unsegregated and segregated genders datasets. Lunge classification on segregated gender datasets showed improvement over the unsegregated gender on 17 out of 21 classification algorithms. The notable improvements were on Trees-Hoeffding Tree (+8.67% on male, +3.08% on female) and Functions-Multilayer Perceptron algorithms (+4.35% on male, +9.37% on female). The study shows that gender segregation improves the lunge classification accuracies.
Segregating Offline and Online Handwriting for Conditional Classification Analysis
Authors: Wong L C , Loh W P 
Published: July 2019

Abstract
Offline and online handwriting patterns vary when exposed to external factors. Recent researches on both type handwriting analysis were focused on the image feature extraction, pattern recognition, and classification approach. However, no studies have considered segregating the conditional effects of handwriting patterns on two categories: offline vs. online and normal vs. vibration. Hence, the main goal of the study was to investigate the effects of classifying induced vibration on the offline and online handwriting patterns. There were 25 experimental handwriting samples retrieved under four pre-defined class: FLN, FLV, NLN, and NLV. Extracted data attributes consisted of seven handwriting size metrics and two demographic data. JRip algorithm and Decision Stump algorithm of WEKA tool were employed on tenfold cross-validation mode for handwriting classification and a further segregation by offline and online handwriting. JRip and Decision Stump merely resulted in 54% and 44% classification accuracy respectively. On data categorization between the offline and online handwriting, both algorithms achieved classification accuracies of 56% and 76% respectively. Findings showed that the misclassifications between offline and online were reduced to 5 and 7 instances for JRip and Decision Stump algorithms respectively, whereas the total misclassification between normal and vibration were reduced to 22 and 13 instances.

Abstract
Here, we present a study into the mechanisms of primary cell wall cellulose formation in grasses, using the model cereal grass Brachypodium distachyon. The exon found adjacent to the BdCESA1 glycosyltransferase QXXRW motif was targeted using Targeting Induced Local Lesions in Genomes (TILLING) and sequencing candidate amplicons in multiple parallel reactions (SCAMPRing) leading to the identification of the Bdcesa1S830N allele. Plants carrying this missense mutation exhibited a significant reduction in crystalline cellulose content in tissues that rely on the primary cell wall for biomechanical support. However, Bdcesa1S830N plants failed to exhibit the predicted reduction in plant height. In a mechanism unavailable to eudicotyledons, B. distachyon plants homozygous for the Bdcesa1S830N allele appear to overcome the loss of internode expansion anatomically by increasing the number of nodes along the stem. Stem biomechanics were resultantly compromised in Bdcesa1S830N. The Bdcesa1S830N missense mutation did not interfere with BdCESA1 gene expression. However, molecular dynamic simulations of the CELLULOSE SYNTHASE A (CESA) structure with modelled membrane interactions illustrated that Bdcesa1S830N exhibited structural changes in the translated gene product responsible for reduced cellulose biosynthesis. Molecular dynamic simulations showed that substituting S830N resulted in a stabilizing shift in the flexibility of the class specific region arm of the core catalytic domain of CESA, revealing the importance of this motion to protein function.
Hepatocyte nuclear factor-1 beta protects endometriotic cells against apoptotic cell death by up-regulating the expression of antiapoptotic genes†

Published: July 2019

AbstractThe overexpression of hepatocyte nuclear factor-1 beta (HNF1β) in endometriotic lesion has been demonstrated. However, the role of HNF1β in endometriosis remains largely unknown. Human endometriotic 12Z cells showed higher level of HNF1β when compared with normal endometrial HES cells. In human endometriotic 12Z cells, HNF1β knockdown increased susceptibility to apoptotic cell death by oxidative stress, while HNF1β overexpression suppressed apoptosis. In addition, HNF1β knockdown and overexpression significantly decreased and increased, respectively, the expression of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB)-dependent antiapoptotic genes. Knockdown of the antiapoptotic genes significantly reduced the HNF1β-induced resistance against oxidative stress in 12Z cells. Furthermore, HNF1β regulated the transcriptional activity of NF-κB, and an NF-κB inhibitor suppressed the HNF1β-enhanced NF-κB-dependent antiapoptotic gene expression and the resistance of the 12Z cells against cell death. Taken together, these data suggest that HNF1β overexpression may protect endometriotic cells against oxidative damage by augmenting antiapoptotic gene expression.
No price without value: towards a theory of value and price
Authors: Elder-Vass Dave 
Published: July 2019

AbstractThe relationship between value and price, a central focus of classical political economy, has fallen into the shadows of neglect in contemporary economics. This paper builds on a critical realist framework and findings from the economics of conventions and the sociology of valuation to develop a theory of value that returns to the relation between value and price. It argues that value is best understood as a view of the price that something ought to exchange at, and that these views are shaped normatively by a host of lay theories of value and the groups and organisations that advance them. Through their effects on our assessments of value, these theories also influence the determination of prices. Although prices in open systems are determined by many interacting factors, lay theories of value play a crucial role in the process.
