Authors: Sahar D P , Afifudin M T , Indah A B R 
Published: October 2020

Abstrak
Supply Chain Management (SCM) is a series of activities related to the flow of goods, information, and finance from suppliers, manufacturers, warehouses, distributors, and retailers to end customers (users). Whereas Green Supply Chain (GSCM) is an environmental innovation that integrates environmental issues and SCM to improve the organization’s sustainable performance. Some literature uses qualitative, quantitative, and a combination of the two methods in analyzing the positive impact of GSCM. Literature study was conducted to determine the impact felt by the company if implementing GSCM in its organization. So that it can be a reference for the manager in deciding the application of GSCM processes in the organization. There are four green processes in GSCM, namely: green design, green manufacturing, green logistics, reconditioning and core disposal. Some positive impacts that can be felt by the company, such as increasing organizational productivity (financially and efficiency), improving environmental performance, and to identify trends in organizational development. This practice can be implemented well if it is supported by pressures from various interests and pressures of the organization (management). Thus forcing companies to perfect the organization’s business model.

Abstract
This study aims to carry out conservation using a traditional approach to the artifacts of Chinese metal coins (kepeng) that are raised from the Sangkulu-kulu Selayar underwater site. The natural ingredients used are a solution of wuluh starfruit (Averrhoa Bilimbi), maja fruit solution (Aegle Marmelos (L) Correa), lime juice (Citrus Aurantifolia), tamarind juice (Tamarindus Indica) and coconut water (Cocoa nutifera). The methods used include identification of weathering. The second stage is of XRF analysis. The third stage is immersion with a conservative ingredients solution. The results showed that of the five solutions used in the cleaning of 3 types of weathering in the coin sample, the lime solution was faster in removing three types of weathering (chemistry, physical and biotic), especially for the types of chemical and biotic weathering. Acidic solutions are used to remove active patina; a tamarind solution is the most effective solution in eliminating physical weathering by a process that lasts slowly or little by little.
Invariance and Controlled Invariance in Switching Structured Systems with Application to Disturbance Decoupling
Authors: Conte G , Perdon A M , Zattoni E , Moog C H , Scharbarg E 
Published: October 2020

Abstract
In this paper, we consider dynamical systems where the graph of the relations between state, input and output variables switches between different configurations, according to the action of a switching time signal. Moreover, in each configuration the relations between the variables are known only for being zero or nonzero. Switching structured systems of this kind are described by families of simple, directed graphs. They can be used to model complex networks of systems as well as systems of systems for which the only available information consists in the patterns that the set of the interconnections between the components, or agents, may assume in different situations. Using an approach that is conceptually similar to the geometric approach developed for linear time-invariant systems, suitable notions of invariance and controlled invariance are introduced and related to the action of feedback. These notions are used to provide general solvability conditions for the disturbance decoupling problem expressed in graph-theoretic terms.

Published: October 2020

Abstract
In this research, a novel Automated Fluid Management System (AFMS) was designed, analysed and fabricated for endoscopy aided gynaecological surgeries in order to prevent complications arise due to fluid overload. The proposed system consists of a peristaltic pump, suction mechanism and fluid measurement system integrated with a graphical user interface which can also control and monitor through a wireless network system. The device serves functionalities such as regulating saline flow rate, limiting saline suction rate, setting saline absorption limits for different patients and indicating real-time fluid deficit. This paper discusses designing of a non-contact pump for gynaecological surgeries, development of the control system for AFMS and the comparison of experimental results of the fabricated non-contact pump with theoretical pump characteristics.

Published: October 2020

Abstract
In the paper, the problem of calculating the deformed state of the inner ring shell of a rotating furnace under high temperature is solved by using harmonic analysis methods. The constructed mathematical model allows us to obtain parameters of furnace’s shell deformation based on an array of displacement, which is measured at the reference points. The reference points define the shape of the shell in the polar coordinate system in a discrete way. The results of the work allow automated processing of the metrological data in order to develop practical recommendations of the constructive and methodological way for the complementation of structural elements and equipment units or thermal control systems, if necessary.
Eccentric Interaction between Strong and Weak Axes in the Design of Asymmetric Angle Steel Strength
Authors: Hsu W T , Chung S T , Liu R Y 
Published: October 2020

Abstract
Steel structural members use many types of material sections and a wide range of sizes. Among them, Angle steel is more economical than I-type due to the use of materials, and is usually used for beam web support and diagonal support. Therefore, this study will analyze the eccentric axis strength change of L-shaped angle steel under the action of biaxial bending moment. The angle steel is divided into equilateral angle steel and unequal angle steel, and the calculation of unequal angle steel is the most complicated. Due to the asymmetry of the axial force, when the angle steel bears an axial force, it will cause eccentric load, which makes it the bending moment caused by the angle steel will change the structure. Therefore, in this study, an unequal-sided angle steel with a length of 10 ft. L8 × 4 × 7/16 was selected as the research object, and the eccentric strength changes of the strong and weak axial forces of the angle steel were analyzed.
Multipoint intermittent fault detection of electronic interconnections using channel sounding techniques
Authors: Kanchwala Husain , Ahmad Syed Wakil 
Published: October 2020

Abstract
Intermittent faults (IFs) in electrical interconnection are short duration transients. These faults are random, non-predictable and non-stationary in nature making them hard to troubleshoot using traditional equipment. They can be detected only if the test equipment has test coverage both in time and area at that instant. This paper proposes a novel approach of intermittent fault detection by injecting a wideband signal and using channel-sounding techniques. A novel Direct Sequence Spread Spectrum (DS-SS) technique is presented for multipoint IF detection and health monitoring. Digital communication sounding technology and its methods devised for detection and classification of an IF, and channel characterisation by its transfer function is discussed in detail. A combination of transmitter and receiver provide an effective tool for continuously monitoring of the multi-point interconnect. The proposed method has been tested using a functional prototype having pre-induced IFs. Intermittent signal is generated by applying external vibration on the connector and intermittency is detected by acquiring and processing the propagated signal. The results demonstrate the effectiveness of the method in detection and classification of intermittent interconnections.

Published: October 2020

Abstract
This research work was undertaken to study the effect of dry sliding wear process parameters such as load, time, and sliding velocity on the wear rate and coefficient of friction of AA8011 with 8 wt.% fly-ash composites. The response surface methodology was used to determine the most important criteria to maximize the wear rate and minimize the coefficient of friction. The experimental procedure was designed based on second-order rotatable central composite design. The optimization studies were carried out on dry sliding wear process parameter with multi-response characteristics, including the wear rate, coefficient of friction, based on multi-criteria decision-making using the TOPSIS approach. Sensitivity analysis was used to identify the important criteria and classify them by their order of importance in model validation. A confirmation test was carried out to validate the results, and the obtained optimal parameter levels were found to be very close to an ideal solution.
Thermomechanical properties of honeycomb lattices from internal-coordinates potentials: the case of graphene and hexagonal boron nitride
Authors: Libbi Francesco , Bonini Nicola , Marzari Nicola 
Published: October 2020

Abstract
Lattice dynamics in low-dimensional materials and, in particular, the quadratic behaviour of the flexural acoustic modes play a fundamental role in their thermomechanical properties. A first-principles evaluation of these can be very demanding, and can be affected by numerical noise that breaks translational or rotational invariance. In order to overcome these challenges, we study the Gartstein internal-coordinate potential and tune its 13 parameters on the first-principles interatomic force constants for graphene. We show that the resulting potential not only reproduces very well the phonon dispersions of graphene, but also those of carbon nanotubes of any diameter and chirality. The addition of a cubic term allows also to reproduce the dominant anharmonic terms, leading to a very good estimate of the lattice thermal conductivity. Finally, this potential form works very well also for boron nitride, provided it is fitted on the short-range (analytical) part of the interatomic force constants, and augmented thereafter with the long-range dielectric contribution. This consideration underscores how potentials based on short-ranged descriptors should be fit, in polar materials, to the short-range part of the first-principles interactions, and complemented by long-range analytical dielectric models parametrized on the same first-principles calculations.

According to calculation, we find Mn–O co-doped MoS2 monolayer has the lowest formation energy in four co-doping systems. Thus the Mn–O co-doped MoS2 monolayer has the best stability. The Mn–Se co-doped MoS2 monolayer has the highest static dielectric constants

Study on high speed impact deformation behaviors of Mg-1Al-4Y by SHPB
Authors: Wang Jinhui , Dong Ningning , Ma Hongbin 
Published: October 2020

Abstract
This study aims to investigate the deformation behaviours of Mg-1Al-4Y alloy by SHPB apparatus under different strain rates at room temperature. Texture evolution analysis of Mg-1Al-4Y specimens were carried out by X-ray diffraction and electron back-scattered diffraction technology. The macro-texture of the specimen in the transverse direction was gradually biased towards [20–21] with the increasing of the strain rate. Furthermore, a large amount of {10–12} extension twins formed in the grains at low strain rate, and partial twin-shaped nuclei grew up to meet, resulting in formation of boundaries with ∼60° misorientation. The grain boundary orientation distribution indicated that the grain size of Mg matrix became smaller and smaller with the growth of twins, which was not conducive to the continued nucleation of twins. Meanwhile, the rotation of grains decreased the Schmid factor of the twins, which led to an obviously reduction in the fraction of the twin nucleation. Therefore, the dynamic deformation mode of Mg-1Al-4Y gradually changed from twin deformation to twin deformation and dislocation slip with the increasing of strain rate.

Published: October 2020

Abstract
Spinal fusion with pedicle-screw-rod is being used widely for treating spinal deformities diseases. Several biomechanical studies on screw rod based implant failure through screw pullout, bending, screw breakage have been performed. But few studies are available regarding the effect of strain for breakage of rod. So, the purpose of the present study is to observe strain at the rod connected with the pedicle screw for different loading condition. The strain in stainless steel (SS) connecting rods for pedicle screw fixation were measured using strain gauge. In order to investigate the bio-mechanical response of lumbar spine with reference to strain in the rod, a simple experimental setup was developed using a specimen of L1-S spine segment. SS rods were used for pedicle screw implant on prototyped lumbar Spine. Prior to testing with pedicle screw, the lumbar spine specimen was also compared with FE results. The strain measured using strain gauges at L3-L4 level on SS rod were within a range of 85 to 310 microstrain under 6, 8, 10 Nm flexion and extension, and for L4-L5 level, these values were within a range of 95 to 440 microstrain. It was found that FE result was higher than the strain gauge result and the error varied between 10.5% to 33% with average error of 22.8%. However similar stain behavior was observed by the FE analysis. The proposed method, as well as the qualitative data, might be helpful for the researchers to understand biomechanical behavior of pedicle-screw implanted spine.
Electro-chemo-mechanically coupled computational modelling of structural batteries
Authors: Carlstedt David , Runesson Kenneth , Larsson Fredrik , Xu Johanna , Asp Leif E 
Published: October 2020

Abstract
Structural batteries are multifunctional composites that combine load-bearing capacity with electro-chemical energy storage capability. The laminated architecture is considered in this paper, whereby restriction is made to a so called half-cell in order to focus on the main characteristics and provide a computational tool for future parameter studies. A thermodynamically consistent modelling approach is exploited for the relevant electro-chemo-mechanical system. We consider effects of lithium insertion in the carbon fibres, leading to insertion strains, while assuming transverse isotropy. Further, stress-assisted ionic transport is accounted for in addition to standard diffusion and migration. The relevant space-variational problems that result from time discretisation are established and evaluated in some detail. The proposed model framework is applied to a generic/idealized material representation to demonstrate its functionality and the importance of accounting for the electro-chemo-mechanical coupling effects. As a proof of concept, the numerical studies reveal that it is vital to account for two-way coupling in order to predict the multifunctional (i.e. combined electro-chemo-mechanical) performance of structural batteries.

Published: October 2020

Abstract
We report the effect of bias stress on the drain current and threshold voltage of n-channel thin-film transistors based on solution processed In2O3 layers. Application of a positive gate bias for variable time-periods led to displacements of the transfer curves in the positive gate bias direction. On switching off the gate bias, the transfer curves returned close to their pre-stress state on a timescale similar to that when the gate bias was switched on. The time dependence of the threshold voltage shift is described well by a stretched-exponential model. The temporal behaviour of the threshold voltage shifts is consistent with charge trapping as the dominant effect, although some defect formation cannot be ruled out.
An automated approach for determining the number of components in non-negative matrix factorization with application to mutational signature learning
Authors: Gilad Gal , Sason Itay , Sharan Roded 
Published: October 2020

Abstract
Non-negative matrix factorization (NMF) is a popular method for finding a low rank approximation of a matrix, thereby revealing the latent components behind it. In genomics, NMF is widely used to interpret mutation data and derive the underlying mutational processes and their activities. A key challenge in the use of NMF is determining the number of components, or rank of the factorization. Here we propose a novel method, CV2K, to choose this number automatically from data that is based on a detailed cross validation procedure combined with a parsimony consideration. We apply our method for mutational signature analysis and demonstrate its utility on both simulated and real data sets. In comparison to previous approaches, some of which involve human assessment, CV2K leads to improved predictions across a wide range of data sets.
How I Diagnose Minimal/Measurable Residual Disease in B Lymphoblastic Leukemia/Lymphoma by Flow Cytometry
Authors: Cherian Sindhu , Soma Lorinda A 
Published: October 2020

AbstractObjectivesAssessment for minimal/measurable residual disease (MRD) is a powerful prognostic factor in B lymphoblastic leukemia/lymphoma (B-LL/L) that is quickly becoming standard of care in assessing patients with B-LL/L posttherapy. MRD can be assessed using methodologies including flow cytometry and molecular genetics, with the former being rapid, relatively inexpensive, and widely applicable in many hematopathology/flow cytometry laboratories.MethodsThis article presents an approach to MRD detection in B-LL/L by flow cytometry through case presentations with illustration of several potential pitfalls. We review normal maturation patterns, antigens used for assessment, flow panels that can be utilized, considerations to be made during therapy, and clinical impact. The benefits and drawbacks when using the “different from normal” and “leukemia associated phenotype” approaches are considered.ResultsEvaluation for MRD in B-LL/L by flow cytometry relies on a knowledge of normal immunophenotypic patterns associated with B-cell maturation in states of rest and marrow regeneration so that one can identify patterns of antigen expression that differentiate abnormal, leukemic populations from regenerating hematogones or B-cell precursors. The nature of therapy can affect normal patterns, a phenomenon especially important to take into consideration given the increased use of targeted therapies in the treatment of B-LL/L.ConclusionsFlow cytometry is widely available in many laboratories and is a cost-effective way to evaluate for B-LL/L MRD. However, panel validation and interpreter education are crucial for accurate assessment.
Why formal objections to the error theory fail
Authors: Streumer Bart , Wodak Daniel 
Published: October 2020

Abstract
Many philosophers argue that the error theory should be rejected because it is incompatible with standard deontic logic and semantics. We argue that such formal objections to the theory fail. Our discussion has two upshots. First, it increases the dialectical weight that must be borne by objections to the error theory that target its content rather than its form. Second, it shows that standard deontic logic and semantics should be revised.

Published: October 2020

AbstractObjectivesAn estimated 125 million workers are exposed to asbestos worldwide. Asbestos is classified by the International Agency for Research on Cancer as a Group 1 carcinogen. The association between occupational asbestos exposure and kidney cancer is not well established however. This study aimed to determine the mortality and incidence of kidney cancer in workers who have been exposed to asbestos. We performed a systematic review and meta-analysis to evaluate the association between occupational asbestos exposure and kidney cancer.MethodsMedline, EMBASE, and Web of Science were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles on occupational asbestos exposure and kidney cancer. The studies reported the standardized mortality ratio (SMR) or standardized incidence ratio (SIR) of kidney cancer in workers exposed to asbestos. SMRs or SIRs with its 95% confidence interval (CI) were pooled using a fixed-effect model.ResultsForty-nine cohort studies involving 335 492 workers were selected for analysis. These studies included 468 kidney cancer deaths and 160 incident cases. The overall pooled-SMR of kidney cancer was 0.95 (95% CI: 0.86–1.05), with no significant heterogeneity (PQ = 0.09, I2 = 24.87%). The overall pooled-SIR of kidney cancer was 0.95 (95% CI: 0.79–1.11), with no significant heterogeneity (PQ = 0.68, I2 = 0.00%). Subgroup analysis did not find any increased association with occupational asbestos exposure. There was no evidence of publication bias with Egger’s test P values of 0.08 for mortality studies and 0.99 for incidence studies.ConclusionsThis systematic review and meta-analysis did not show evidence of association between occupational asbestos exposure and kidney cancer mortality or incidence.
