Industry 4.0 Adoption in Manufacturing Industries Using Technology-Organization-Environment Framework

This paper investigated the determinant factors affecting the Industry 4.0 ecosystem needed for the digitization and automation of manufacturing industries. The 4th industrial revolution implements a value chain by interfacing internet of things devices and robotics, data processing in the cloud using artificial intelligence-based analytics. The study was conducted in Pune, India, a manufacturing and IT services hub. It sought to identify Industry 4.0 facilitators and inhibitors by framing empirical data collected from 320 manufacturing facilities and analyzed using PLS-SEM within a model based on technology-organization-environment (TOE) theory and motivation-threat-ability (MTA) theory. The results confirmed that technology competence, organization scope, consumer readiness, competitive pressure, trading partners' readiness, and governance practices are the facilitators, whereas organization resistance inhibits Industry 4.0 adoption intentions. The outcome of this study shall provide guidelines to manufacturing industries management as well as technology solution providers.
Developing Secondary School Students' Foreign Language Speaking Skills in the Netherlands: A Design Research Study

The aim of this design research project was to investigate possible ways of developing foreign language (i.e. English) speaking skills of secondary school students who do not readily speak English in class. It was felt that an intervention was required to raise student-speaking skills in preparation for their oral exam. Empirical data were collected and a literature review was conducted in order to have a deeper understanding of the problem. The data collection methods of the study were questionnaires, interviews, lessons observations as well as a course book analysis. The data collected indicated that speaking production can be affected by a number of criteria such as anxiety, confidence, lack of vocabulary and/or practice. The data collection and the literature review informed the designed product (i.e. series of six lessons focusing on developing students' speaking skills). The product was trialled during May 2020 and both teachers and students were asked for their assessment of the product. The evaluation data were collected through interviews and questionnaires. The evaluation of the product showed that both teachers and students received the product positively and it was found to have had positive effect in changing students' perception of their speaking ability. The results of this study encourage teachers to deviate from textbooks that do not extensively focus on oral production and come up with alternative products to increase student-speaking time in foreign language education.
Half-Select Disturb-Free 10T Tunnel FET SRAM Cell With Improved Noise Margin and Low Power Consumption

Tunnel field-effect transistors (TFETs) have become a potential candidate for replacing traditional MOSFETs in ultralow-power applications, in future. However, the forward p-i-n current of the TFET can seriously deteriorate the performance of the static random-access memory (SRAM) circuit. This brief proposes a half-select disturb-free 10T TFET SRAM cell with cascode isolation transistors. The proposed 10T SRAM cell can avoid the forward p-i-n current, drastically decreasing its leakage power consumption. At a supply voltage of 0.6 V, the leakage power consumption of the proposed 10T TFET SRAM cell is approximately four orders of magnitude lower than those of the outward-facing access transistor 6T (O_6T)/7T and the Schmitt–Trigger 10T (ST_10T) SRAM cells; the write power consumption is approximately 97% and 98% lower than those of the O_6T/7T/ST_10T and the combinational access 10T (CA_10T) SRAM cells, respectively. Moreover, the 10T SRAM cell exhibits 20% and 57% higher read static noise margin(RSNM) than those of the O_6T/7T and ST_10T cells, 115% and 411% higher write static noise margin(WSNM) than those of O_6T/7T and CA_10T, respectively, 20% higher hold static noise(HSNM) than those of O_6T/7T/ST_10T cells, and 89.8% lesser write delay than that of CA_10T at VDD = 0.6V, indicating that the proposed 10T SRAM cell has great potential for ultra-low power applications.
Dynamic characteristic of a new fractional-order chaotic system based on the Hopfield Neural Network and its digital circuit implementation

In this paper, based on the principle of activation function between the neurons, we designed a Hopfield neural network (HNN) chaotic system. And then we defined a fractional-order HNN chaotic system by Caputo definition. The solution of the fractional-order HNN chaotic system is calculated by Adomain decomposition method (ADM). Then the dynamic performances of the fractional-order HNN chaotic system are analyzed through attractor phase diagram, bifurcation diagram, Lyapunov exponent spectrum, fractal dimension, chaotic diagram and SE complexity. In addition, the system is digital circuit implemented based on DSP platform. The experimental results show that the fractional-order HNN chaotic system not only has rich dynamic behavior, but also has complex nonlinear phenomena such as attractor coexistence which is sensitive to initial value. Therefore, this system has good potential application value, it can be used as multi-source pseudo-random number generator, and the generated pseudo-random sequence can be used in chaotic cryptography and secure communication.
An Effective Data Sharing Scheme Based on Blockchain in Vehicular Social Networks

Vehicular social networks (VSNs) are the vehicular ad hoc networks (VANETs) that integrate social networks. Compared with traditional VANETs, VSNs are more suitable to serve a group of vehicles with common interests. In VSNs, vehicles can upload the necessary data in the cloud service provider (CSP) and other vehicles can query the data they are interested in through CSP, which enables VSNs to provide more user-friendly services. However, due to the wireless network communication environment, the data sent by the vehicle can easily be monitored. Adversaries are able to violate the privacy of the vehicle based on the collected data, thereby threatening the security of the entire network. In addition, if a vehicle shares malicious or false data with other vehicles, it is easy to mislead drivers and even cause serious traffic accidents. This paper proposes an effective data sharing scheme based on blockchain in VSNs. By integrating an identity based signature mechanism and pseudonym generation mechanism, we first propose an anonymous authentication mechanism as the basis for establishing trust relationships before data transmission between entities in VSNs. Then, a data sharing scheme based on blockchain is described, in which the signature mechanism and the consensus mechanism guarantee the security and traceability of data. The result of the performance analysis and the simulation experiment indicate that VAB can achieve a favourable performance compared with existing schemes.
EMT: Elegantly Measured Tanner for Key-Value Store on SSD

With the emergence of big data era, NoSQL key-value database is considered as a promising candidate for replacing relational database management system (RDBMS). As cost per GB of flash memory is getting closer to HDD, high performance solid state drive (SSD) is regarded as the best substitute of HDD. However, there are still some issues that need to be taken into consideration. et al. have reported that applying key-value store to SSD with conventional FTL would incur internal fragmentation and further cause the degradation of device lifespan. Although they proposed KVFTL to deal with the above issues, their work gave rise to the read amplification problem. In this article, we investigate the root cause of the read amplification problem and propose elegantly measured tanner FTL (EMT-FTL) to mitigate internal fragmentation and read amplification with acceptable memory overhead. Different from KVFTL that slices a variable-sized value into multiple partitions (up to 20) of different sizes and manages them as a linked chain, EMT-FTL slices a value into 16 KiB full partitions with its remaining bytes treated as a fragment partition and appended to the fragment buffer. For a 64 GiB SSD with 16 KiB pages, the overall memory usage of EMT-FTL is only 8.81% of KVFTL. The experiments showed that EMT-FTL achieved almost the optimal space utilization as KVFTL did under most of traces and averagely improved the get performance by 78.57% (compared with KVFTL) under the traces with request sizes ranging from 1 byte to 16 KiB.
Design of 3-Dimensional Hierarchical Architectures of Carbon and Highly Active Transition Metals (Fe, Co, Ni) as Bifunctional Oxygen Catalysts for Hybrid Lithium–Air Batteries

Flexible power sources and efficient energy storage devices with high energy density are highly desired to power a future sustainable community. Theoretically, rechargeable metal–air batteries are promising candidates for the next-generation power sources. The rational design of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalysts with high catalytic activity is critical to the development of efficient and durable metal–air batteries. Herein, we propose a novel strategy to mass synthesize nonprecious transition-metal-based nitrogen/oxygen codoped carbon nanotubes (CNTs) grown on carbon-nanofiber films (MNO-CNT-CNFFs, M = Fe, Co, Ni) via a facile free-surface electrospinning technique followed by in situ growth carbonization. With a combination of the high catalytic activity of Fe-catalyzed CNTs and the efficient mass-transport characteristics of 3D carbon fiber films, the resultant flexible and robust FeNO-CNT-CNFFs exhibit the highest bifunctional oxygen catalytic activities in t.
Case Report: An Atypical Form of Familial Partial Lipodystrophy Type 2 Due to Mutation in the Rod Domain of Lamin A/C

Purpose Familial partial lipodystrophy type 2 (FPLD2) patients generally develop a wide variety of severe metabolic complications. However, they are not usually affected by primary cardiomyopathy and conduction system disturbances, although a few cases of FPLD2 and cardiomyopathy have been reported in the literature. These were all due to amino-terminal heterozygous lamin A/C mutations, which are considered as new forms of overlapping syndromes. Methods and Results Here we report the identification of a female patient with FPLD2 due to a heterozygous missense variant c.604G>A in the exon 3 of the LMNA gene, leading to amino acid substitution (p.Glu202Lys) in the central alpha-helical rod domain of lamin A/C with a high propensity to form coiled-coil dimers. The patient’s cardiac evaluations that followed the genetic diagnosis revealed cardiac rhythm disturbances which were promptly treated pharmacologically. Conclusions This report supports the idea that there are “atypical forms” of FPLD2 with cardiomyopathy, especially when a pathogenic variant affects the lamin A/C head or alpha-helical rod domain. It also highlights how increased understanding of the genotype-phenotype correlation could help clinicians to schedule personalized monitoring of the lipodystrophic patient, in order to prevent uncommon but possible devastating manifestations, including arrhythmias and sudden death.
Hybrid Model Predictive Control of Semiactive Suspension in Electric Vehicle with Hub-Motor

In hub-motor electric vehicles (HM-EVs), the unbalanced electromagnetic force generated by the HM will further deteriorate the dynamic performance of the electric vehicle. In this paper, a semiactive suspension control method is proposed for HM-EVs. A quarter HM-EV model with an electromechanical coupling effect is established.The model consists of three parts: a motor model, road excitation model and vehicle model. A hybrid model predictive controller (HMPC) is designed based on the developed model, taking into account the nonlinear constraints of damping force. The focus is on improving the vertical performance of the HM-EV. Then, a Kalman filter is designed to provide the required state variables for the controller. The proposed control algorithm and constrained optimal control (COC) algorithm are simulation compared under random road excitation and bump road excitation, and the results show that the proposed control algorithm can improve ride comfort, reduce motor vibration, and improve handling stability more substantially.
BIOGAS PRODUCTION FROM WHEAT STRAW PRE-TREATED WITH LIGNINOLYTIC FUNGI AND CO-DIGESTION WITH PIG SLURRY

This study carried out for the first time a comparison among ligninolytic (white-rot) and cellulosolytic or xylanolytic (Trichoderma) pre-treated wheat straw, for biogas production, potential, without or with pig slurry in co-digestion. Methane (CH4) production from wheat straw pre-treated for 4 and 10 weeks with seven different fungal isolates was preliminarily measured. Then, the effects on biogas yield of the co-digestion with pig slurry were checked on straw pre-treated with 3 selected fungal strains. The maximum production of CH4 from pre-treated straw with Ceriporiopsis subvermispora (SUB) for 4 and 10 weeks was higher than the control (16% and 37%, respectively). The accumulation daily rate was higher than control (42% and 81%, respectively). A positive correlation between CH4 accumulation daily rate and straw enzymatic digestibility was found. In co-digestion with pig slurry, SUB pre-treated straw for 10 weeks showed an accumulation daily rate of 17.4 mL d-1 g-1 VS, significantly higher (17%) than that of the control. The time to reach the maximum CH4 production was shortened on average from 34 to 21 days in co-digestion with pig slurry, in comparison with pre-treated mono-digested wheat straw. The biological pre-treatment with selected white-rot fungi appears a promising technology to increase methane production from wheat straw.
Characterization of  self-anticipated surgical pain prior to general anesthesia - a prospective observational study

Background: Current postoperative pain management principles are primarily based on the type and extent of surgical interventions. This clinical study measured patient’s self-anticipated pain score before surgery and compared the scores with the pain levels and analgesic requirements after surgery.Methods: This prospective observational study recruited consecutive patients who received general anesthesia for elective surgeries in E-Da Hospital (Taiwan) between June and August 2018. Patients were asked to subjectively rate their highest anticipated pain level (numerical rating scale, NRS 0-10) for their scheduled surgical intervention during their preoperative anesthesia assessment. After the operation, the actual pain intensity (NRS 0-10) experienced by the patient in the post-anesthesia care unit (PACU) and the total dose of opioids administered during the perioperative period were recorded. Pain scores ³4 on the NRS were regarded as being unacceptable levels of anticipated or postoperative pain.Results: A total of 857 patients were included in the study. The final database included 49.2% males, and 73.7% of them have had previous operations. The mean anticipated pain score was 4.9±2.5 and 72.2% of the patients reported an anticipated NRS ³4 before their operations. Females anticipated significantly higher overall pain intensities than male patients (adjusted odds ratio 1.695, 95% confidence interval 1.252-2.295; P=0.001). Patients over 40 years of age reported significantly lower overall anticipated NRS scores (4.78±2.49 vs 5.36±2.50; P=0.003). Patients scheduled to receive more invasive surgical procedures were more likely to anticipate high pain intensity in the preoperative period (P<0.001). Higher anticipated pain scores (preoperative NRS³4) were associated with higher actual postoperative pain levels (P=0.032) in the PACU and higher total equivalent opioid use (P=0.001) for acute pain management during the perioperative period.Conclusion: This observational study found that females, younger patients (£40 years), and patients scheduled for more invasive surgeries anticipate significantly higher surgery-related pain. Therefore, appropriate preoperative counseling for analgesic control and management of exaggerated pain expectation in these patients are necessary to improve the quality of anesthesia delivered and patient’s satisfaction.
Management of Herpesvirus Infections in Hematopoietic Cell Transplant Recipients

Following primary infection, herpesviruses establish latency in infected individuals in the host cells and may reactivate upon external stimuli and during periods of immunosuppression. The objective of this paper was to the present current strategies on preventive and therapeutic management of infections with herpesviruses in recipients of hematopoietic cell transplantation. Strategies of antiviral management include prophylaxis, pre-emptive treatment and targeted treatment. Empirical therapy is not used in antiviral strategies. Prophylaxis can be done at universal (preventive strategy) and specific level. Universal prophylaxis includes non-pharmacologic methods of prevention of infection or reactivation. Risk-adapted specific prophylaxis includes use of specific antivirals or cellular therapy or other specific methods in order to prevent specific infection, in high-risk groups. Pre-emptive therapy means use of therapeutic approaches in asymptomatic infection, detected by a screening assay. Targeted therapy is used in established specific viral end-organ infections. The following sections of the paper refer to prophylaxis and treatment strategies, respectively, against CMV, EBV, HSV, VZV, HHV-6, HHV-7, and HHV-8 after allogeneic hematopoietic cell transplantation.
A Novel Nonisolated Buck–Boost Converter With Continuous Input Current and Semiquadratic Voltage Gain

A buck–boost dc–dc converter with semi-quadratic voltage gain is introduced in this article. The proposed converter benefits from continuous input current and common ground characteristic between input–output voltage ports. Due to low ripple input current, the proposed converter is a proper choice for carbon-free power sources such as photovoltaic (PV). Unlike the traditional buck–boost converter, the presented converter offers positive output voltage and large voltage gain without using an extreme duty cycle. In addition, the voltage stresses across the power switches of the proposed converter are very low compared with the output voltage. Hence, power switches with low on-resistance are used in practical implementation, which leads to power loss reduction and efficiency improvement. The performance principles, dc analysis, modeling process, and power loss analysis of the proposed converter are fully described. Finally, a laboratory prototype is implemented so as to evaluate the previously mentioned features of the proposed converter.
The mixing of cohesive and flowable powder materials using a common laboratory powder mixer

This study presented the homogeneity obtained when mixing cohesive and flowable powder materials using a laboratory powder mixer. The mixing process parameters studied were the mixing time and the mixer rotational speed (20 rpm, 40 rpm and 60 rpm) at the different ratios (95%: 5%, 50%: 50% and 5%: 95%) of the cohesive cocoa and flowable mannitol powder materials. The homogeneity sampled at the powder bed surface showed that only at the highest rotational speed of 60 rpm used in this work yield acceptable homogeneity at the two extremes of the powder mass ratios; 95%: 5% and 5%: 95% of mannitol: cocoa for some of the locations on the powder bed surface, especially near the wall of the mixer. Other combinations of the experimental conditions did not yield acceptable mixture homogeneity. These results showed the difficulties in obtaining a homogeneous powder mix when mixing cohesive powder materials, especially in academic teaching and research laboratories using a simple powder mixer apparatus.
Laser-induced Fluorescence Studies of Cm3+ Complexes in Solution

Photophysical studies of complexed Cm + in solution have been carried out using a laser-induced fluorescence method. The luminescence decay rate of the first excited J = lj2 state of Cm + was measured using carbonate, nitrate, and two extractant aminocarboxylic acids as complexing ligands in aqueous solution. Cm(C104)3 dissolved in methyl sulfoxide also was studied. Solvent deuteration provided insight into the dominant nonradiative luminescence quenching mechanism which was found to be electronic-to-vibrational energy transfer. Emission spectra of Cm 3 + complexed by the various ligands studied are reported. Prior spectroscopic and photophysical studies of Cm 3 + in solution are reviewed.
ETHNOMATHEMATICS: PRANATAMANGSA SYSTEM AND THE BIRTH-DEATH CEREMONIAL IN YOGYAKARTA

Mathematics exists as rooted in human ideas, ways, and techniques to respond to their environments. Along with its development, mathematics has been taught through formal education or schooling in the flat- not flexible ways and far from students' social and cultural lives. Indonesia is rich with culture, including the Special Region of Yogyakarta (DIY). It is called a city of culture. Educators are not yet aware of this richness in the learning process to integrate it as the starting point. It is hard to find in mathematics textbooks in Indonesia, which put cultural context as starting points. Therefore, this study aims to explore Yogyakarta's culture in terms of contexts used in mathematics learning. It is an ethnography study. Furthermore, the data was collected through literature artifacts, field observation, and interviews with resource persons who understand the seasons, system, and calculation of birth and death days. It is to clarify the researcher's understanding of the literature. This study showed that Yogyakarta's people use mathematical modeling to determine the seasons' system and funerary dates. These models have the potential to be used as a starting point in learning mathematics.
Compact Multiport MIMO Antenna System for 5G IoT and Cellular Handheld Applications

A low-profile, compact, four-element, eight-port multiple-input--multiple-output and diversity antenna for 5G Internet of Things and cellular handheld applications is presented in this letter. This antenna structure contains four antenna elements, which are same in its configuration. The antenna ground dimensions are taken similar to a modern mobile handset, i.e., 60 mm × 120 mm. The four antenna elements are situated at four corners of antenna ground structure. Each antenna element has two feeding ports, thus making a total of eight-port antenna. A single antenna element has two feeding plates, which are placed perpendicular to one another so that they become cross polarized, thus exploiting polarization diversity, whereas spatial diversity also exists between different antenna elements. For reducing mutual coupling between different antenna ports, slots are cut in ground plane, including a small strip etched along the entire length of ground plane and rectangular slots cut in ground plane under every antenna element. The minimum bandwidth attained by all eight ports for S11 < –10 dB is more than 1.4 GHz from 2.4 GHz to more than 3.8 GHz, which testify that it covers majority of frequency bands allocated for 5G sub-6 GHz spectrum. The isolation obtained between different ports has a minimum value of –13 dB, and the maximum value goes below –30 dB. For the covered frequency bands by this antenna structure, the correlation coefficient is found to be below 0.03, whereas the measured peak gain is in the range of 3.2--5 dB.
