FAKTOR-FAKTOR YANG MEMPENGARUHI PENERIMAAN USER TERHADAP PENERAPAN QUICK RESPONSE INDONESIA STANDARD SEBAGAI TEKNOLOGI PEMBAYARAN PADA DOMPET DIGITAL

Quick Response Indonesia Standard (QRIS) is the QR Code which is standardized by Bank Indonesia as the technology used for the cashless payment method. It has been released officially since January 2020. The aim of this standardization is to provide an easier and more efficient payment method by QR Code technology. The electronic wallet's providers which are already implemented QRIS as their payment technology are Go-Pay and OVO. The goal of this research is to predict the factors affecting the user acceptance of QRIS implementation as the electronic wallet’s payment technology. The user acceptance regarding the QRIS implementation is predicted by user technology acceptance model called UTAUT 2. The variables used in this research are all UTAUT 2 model variables except age, gender, experience, and price value. The method used for analysing the data in this research is PLS-SEM. The result of this research shows that the facilitating conditions and hedonic motivation affect the user's behavioral intention for using QRIS as their payment technology, and this behavioral intention also gives the effect to their use behavior.
Accurate Analytical Method for Magnetic Field Calculation of Interior PM Motors

In this article, a rotor magnetic potential (RMP) model is proposed, which can accurately describe the rotor surface magnetic potential distribution under the interaction of multi-excitation sources. Furthermore, a new magnetic equivalent circuit (MEC) model is used to model the complex saturation in the bridge region, which employs an improved nonlinear reluctance modeling method. Then, the unknown parameters in the RMP model are obtained by solving the MEC model. In this article, the RMP model and MEC model are combined to consider the stator and rotor saturation effects, and the magnetic field is calculated accurately. Compared with the existing RMP model, the proposed one can take into account the effects of the stator saturation and PM magnetic field. Compared with the existing MEC and equivalent magnetic network (EMN), the area of the nonlinear reluctance in this paper varies with excitation conditions, which can accurately consider the saturation effects in the bridge region. This improvement can improve calculation accuracy on the basis of reducing the number of nonlinear reluctances. Moreover, the proposed method does not need to consider the change of the air-gap reluctances caused by rotor rotation. Finally, the proposed method is verified by both finite element analysis and experiments.
Computational study of structural, electronic and optical properties of molybdenum chalcogenides

Based on first principles calculations the structural, mechanical stability and electronic properties of molybdenum chalcogenides 2H-MoX2 (X = S, Se, Te) have been studied using density functional theory (DFT). The generalized gradient approximation (GGA) proposed by Perdew, Burke and Ernzerhof (PBE) was employed together with the projector augmented plane wave (PAW) method. The van der Waals interactions in the Grimme (DFT-D2) and Lundqvist and Langreth (vdW-DF) approximations have been added on top of PBE or revised PBE in order to take into account the weak interactions between layers of 2H-MoX2 (X = S, Se, Te). The structural properties include the equilibrium lattice parameters, the cohesive energy and the formation energy. Besides we have studied the mechanical stability of these compounds by examining the elastic constants using the PBE, vdW-DF, and DFT-D2 approximations. Other quantities related to the mechanical properties such as the Young’s modulus, the Poisson’s ratio and the bulk modulus were also calculated. Electronic properties of bulk 2H-MoX2 (X = S, Se, Te) have been investigated using density functional theory (via band structure and projected density of state), and a partially self-consistent GW (GW0) approximation. We have investigated electronic properties ( band structure) for monolayers 1H-MoX2 (X = S, Se, Te) using a single shot GW (G0W0) approximation. Optical properties for monolayer 1H-MoX2 (X = S, Se, Te) were studied using the Bethe-Salpeter equation (BSE).
SPATIAL VARIABILITY IN GREENHOUSE GAS FLUXES OF A TEMPERATE FRESHWATER MARSH IN CHINA: EFFECTS OF SOIL MOISTURE, ANIMAL ACTIVITIES AND LAND USE

The greenhouse gas (CH4, N2O and CO2) fluxes from Shengjin Lake Marsh (SLM) were in situ investigated at the undisturbed sites and the disturbed sites by animal colonization and human activities. Overall the CH4 emissions from the wet sites were one order of magnitude higher than those from the mesic or dry sites, whereas higher N2O emissions and net CO2 uptake occurred at dry sites rather than at mesic and wet sites. Soil moisture was the predominant factor controlling the spatial variability in marsh CH4 and N2O fluxes and NEE at undisturbed sites. Mean CH4 fluxes from migrating water bird and poultry active areas showed no statistically significant differences from the undisturbed sites, but their activities significantly increased N2O emissions and decreased marsh CO2 sink, with the highest N2O fluxes (mean 49.5±11.9 μg N2O m h) in poultry active areas. The conversion of the marsh into agricultural field and landfill did not significantly change CH4 and N2O fluxes, but significantly decreased CO2 sink. Our results revealed that the accurate evaluation of GHG budget for the SLM and other similar temperate wetlands should involve soil water regimes, water bird colonization and human-induced
Floristic analysis of Mt Slivenska (Eastern Stara Planina, Bulgaria)

Investigation of biological diversity is an important prerequisite for environment protection and is particularly topical in the context of the ongoing climate changes and altering public awareness of the strong connection between Man and Nature. The paper presents floristic diversity of Mt Slivenska. Presence of 1217 species has been identified, belonging to 458 genera, 95 families, five classes, and four divisions. Criteria for the elementary flora have been met. The great number of endemics, relicts and conservationally important taxa, and a comparative analysis with other similar regions, define the importance of the territory for the protection of floristic diversity. For the achievement of this goal, it will be necessary to create a monitoring system in the protected territories and areas of the region.
Improved Interleaved Discontinuous PWM for Zero-Sequence Circulating Current Reduction in Three-Phase Paralleled Converters

Interleaving is widely used in paralleled converters to enhance the output current quality, but subsequent circulating currents could lead to harmonic distortion and extra power losses. This article proposes an improved interleaved discontinuous pulsewidth modulation (IIDPWM) method to reduce zero-sequence circulating currents (ZSCC) in paralleled converters with common dc and ac bus. For two-paralleled converters, optimal vector sequences are selected considering minimal common-mode voltage (CMV) differences, the NTVs principle, and power losses. Furthermore, a novel carrier-based scheme is presented to implement the proposed strategy in a general case with any number of paralleled units. The 180$^\circ$ carrier phase shift between two unclamped phase legs in discontinuous PWM is first applied for ZSCC reduction. Compared to existing works, the proposed strategy shows a practical value achieving good overall performance in ZSCC, output currents, switching losses, ease of use and scalability. Simulation and experimental results verified the effectiveness of the proposed IIDPWM strategy.
A Flexible Capacitive 3D Tactile Sensor With Cross-Shaped Capacitor Plate Pair and Composite Structure Dielectric

This paper presents a novel flexible capacitive 3D tactile sensor using cross-bar polydimethylsiloxane (PDMS) walls and micropillar arrays as the composite structure dielectric layer. The tactile sensor unit consists of a $2\times 2$ capacitor array where electrode pairs are arranged in a cross-bar pattern to ensure a fixed overlap area for these capacitors. A top bump is introduced for the sensor to ensure the force is applied uniformly on the sensor. When a force is applied on the sensor, it changes the capacitances of the four capacitors, distinguishing the forces from different directions. The sensitivities of the sensor in the x-, y- and z- directions are 95.08%/N, 98.30%/N and 237.48%/N, in the ranges of 0-0.15 N, 0-0.15 N and 0-0.1 N respectively, much better than most of reported ones. The high sensitivities of the proposed sensor unit are attributed to the composite structure dielectric layer and the optimized Young’s modulus of PDMS. The flexible capacitive tactile sensor shows great potential for applications in robot technology.
Pupils’ Motivation and Perceptions on ESL Lessons through Online Quiz-Games

Some scholars believe that the English proficiency and literacy level among the pupils in this country is deteriorating alarmingly and to overcome this issue, many measures have been taken by the government. Research showed that this issue could be caused by lack of motivation among learners to use English in their lives. This study examined pupils‟ motivation and perceptions of ESL lessons through online quiz-games namely Kahoot! and Quizizz. There were 60 primary school learners involved in this study. Data were collected using a survey questionnaire, and were analyzed and discussed quantitatively in descriptive analysis. The findings revealed that these learners had an elevated motivation and positive perceptions on the inculcation of online quizgames in English lessons. The positive responses shown by the pupils have reflected their positive motivation, perceptions and acceptance towards learning English with the integration of online quiz-games like Kahoot! and Quizizz. This is because the elements of fun, enjoyment and competition in games can make students more motivated and interested in learning English.
The Term Structures of Loss and Gain Uncertainty

Nous etudions l’incertitude liee au rendement des actions pour differents horizons de placement. Comme le rendement est une perte ou un gain, nous classons l’incertitude liee au rendement dans l’une ou l’autre de ces deux categories : l’incertitude liee a une perte, c’est-a-dire l’incertitude entourant les rendements negatifs, et l’incertitude liee a un gain, soit celle relative a tout gain realise a l’avenir. Les occasions de placement peuvent etre evaluees en fonction de ces deux categories. Afin de mesurer les deux categories d’incertitude pour differents horizons de placement, nous utilisons des donnees tirees d’un vaste echantillon d’options liees a l’indice S&P 500 dont le temps avant l’echeance va de un mois a un an. Nous verifions egalement si les modeles d’evaluation des options de forme reduite qui existent deja peuvent produire des resultats similaires. Nous constatons que, en moyenne, plus la duree jusqu’a l’echeance est longue, plus les investisseurs s’attendent a ce que le risque de perte diminue. Cela dit, sur le marche, il coute plus cher de couvrir le risque de perte a long terme des actions que de couvrir celui a court terme. De la meme facon, nous constatons que, en moyenne, plus la duree jusqu’a l’echeance est longue, plus les investisseurs s’attendent a ce que le potentiel de gain augmente. On remarque toutefois que, sur le marche, il coute presque tout autant de speculer sur les gains potentiels a court terme des actions que de speculer sur ceux a long terme.
Contrastive Adversarial Domain Adaptation for Machine Remaining Useful Life Prediction

Enabling precise forecasting of the remaining useful life (RUL) for machines can reduce maintenance cost, increase availability, and prevent catastrophic consequences. Data-driven RUL prediction methods have already achieved acclaimed performance. However, they usually assume that the training and testing data are collected from the same condition (same distribution or domain), which is generally not valid in real industry. Conventional approaches to address domain shift problems attempt to derive domain-invariant features, but fail to consider target-specific information, leading to limited performance. To tackle this issue, in this article, we propose a contrastive adversarial domain adaptation (CADA) method for cross-domain RUL prediction. The proposed CADA approach is built upon an adversarial domain adaptation architecture with a contrastive loss, such that it is able to take target-specific information into consideration when learning domain-invariant features. To validate the superiority of the proposed approach, comprehensive experiments have been conducted to predict the RULs of aeroengines across 12 cross-domain scenarios. The experimental results show that the proposed method significantly outperforms state-of-the-arts with over 21% and 38% improvements in terms of two different evaluation metrics.
Gap junctions set the speed and nucleation rate of stage I retinal waves

Spontaneous waves in the developing retina are essential in the formation of the retinotopic mapping in the visual system. From experiments in rabbits, it is known that the earliest type of retinal waves (stage I) is nucleated spontaneously, propagates at a speed of 451±91 μm/sec and relies on gap junction coupling between ganglion cells. Because gap junctions (electrical synapses) have short integration times, it has been argued that they cannot set the low speed of stage I retinal waves. Here, we present a theoretical study of a two-dimensional neural network of the ganglion cell layer with gap junction coupling and intrinsic noise. We demonstrate that this model can explain observed nucleation rates as well as the comparatively slow propagation speed of the waves. From the interaction between two coupled neurons, we estimate the wave speed in the model network. Furthermore, using simulations of small networks of neurons (N≤260), we estimate the nucleation rate in form of an Arrhenius escape rate. These results allow for informed simulations of a realistically sized network, yielding values of the gap junction coupling and the intrinsic noise level that are in a physiologically plausible range. Author summary Retinal waves are a prominent example of spontaneous activity that is observed in neuronal systems of many different species during development. Spatio-temporally correlated bursts travel across the retina at a few hundred μm/sec to facilitate the maturation of the underlying neuronal circuits. Even at the earliest stage, in which the network merely consists of ganglion cells coupled by electric synapses (gap junctions), it is unclear which mechanisms are responsible for wave nucleation and transmission speed. We propose a model of gap-junction coupled noisy neurons, in which waves emerge from rare stochastic fluctuations in single cells and the wave’s transmission speed is set by the latency of the burst onset in response to gap-junction currents between neighboring cells.
The Effects of COVID 19 Process on Health Care Workers: Analysing of the Relationships between Optimism, Job Stress and Emotional Exhaustion

espanolEsta investigacion se ha centrado en determinar los niveles de optimismo, estres y agotamiento emocional de profesionales de la salud relacionados con COVID-19 y el efecto directo e indirecto del optimismo en el agotamiento emocional causado por Covid-19(a traves del estres laboral). Los datos fueron recolectados a traves de un cuestionario en linea con escalas de optimismo, estres laboral y agotamiento emocional organizadas de acuerdo con COVID-19. Los datos recopilados de 169 profesionales de la salud que trabajan en una ciudad de Turquia se analizaron utilizando diferentes programas estadisticos. Los resultados obtenidos han demostrado que los empleados son bastante optimistas en este proceso, y tambien han experimentado estres y agotamiento emocional a pesar de que sus niveles son mas bajos que el optimismo. Ademas, se ha determinado que ser optimista a pesar de COVID-19 afecta el agotamiento emocional causado por COVID-19, tanto directa como indirectamente a traves del estres laboral. Por lo tanto, el nivel de optimismo en este proceso ha reducido el agotamiento emocional causado por COVID-19. Sin embargo, esta disminucion se sintio mas fuerte a traves del estres. Estos hallazgos han contribuido tanto a los gerentes de atencion medica como a las instituciones oficiales relevantes, y a las investigaciones relacionadas con COVID-19. EnglishThis research has focused on determining the levels of optimism, stress and emotional exhaustion of health care workers related to COVID-19 and the effect of optimism directly and indirectly (through job stress) on emotional exhaustion caused by Covid-19. The data were collected through an online questionnaire with optimism, job stress and emotional exhaustion scales arranged according to COVID-19. The data collected from 169 health care workers working in a city in Turkey were analysed using different statistical programs. The findings obtained has shown that the employees are quite optimistic in this process, and they have also experienced stress and emotional exhaustion even though their levels are lower than optimism. Also, it has been determined that being optimistic despite COVID-19 affects emotional exhaustion caused by COVID-19 both directly and indirectly through work stress. Therefore, the level of optimism in this process has reduced the emotional exhaustion caused by COVID-19; however, this decrease was felt stronger through stress. These findings have contributed to both healthcare managers and relevant official institutions, and to researches related to COVID-19.

Sustainable Development of Fintech: Focused on Uncertainty and Perceived Quality Issues

Despite high expectations for the growth of Fintech, it has not reached the expected growth in the real world. As Fintech is innovative but inherently unpredictable, customers are still hesitant to adopt and use Fintech, which ultimately affects its growth. To achieve the sustainable development and growth of Fintech, an in-depth investigation of Fintech continuance intentions is required. To investigate continuous-use behavior in a Fintech context, this study focuses on two relevant issues: uncertainty and information technology (IT) quality. Uncertainty is more critical in Fintech than in traditional e-banking transactions because Fintech transactions are complicated and less predictable. IT quality is also crucial to Fintech success because IT plays a key role in Fintech transactions. This study mainly explores the relationship between uncertainty and IT quality, both of which significantly affect Fintech continuance intentions. For the purpose, we integrated an IT quality–based perspective with a trust-based model to investigate Fintech continuance intentions. Our results demonstrate that system quality is negatively related to perceived risk, whereas information quality is positively related to trust. Service quality is the most important quality factor for controlling uncertainty and encouraging continued use of Fintech. We found a more extended role of IT in Fintech than in other digital services. This study provides Fintech providers with the practical guidance in the design and implementation of Fintech innovation, thereby achieving the sustainable development of Fintech.
Class-Wise Distribution Adaptation for Unsupervised Classification of Hyperspectral Remote Sensing Images

—Class-wise adversarial adaptation networks are investigated for the classiﬁcation of hyperspectral remote sensing images in this article. By adversarial learning between the feature extractor and the multiple domain discrimi-nators, domain-invariant features are generated. Moreover, a probability-prediction-based maximum mean discrepancy (MMD) method is introduced to the adversarial adaptation network to achieve a superior feature-alignment performance. The class-wise adversarial adaptation in conjunction with the class-wise probability MMD is denoted as the class-wise distribution adaptation (CDA) network. The proposed CDA does not require labeled information in the target domain and can achieve an unsupervised classiﬁcation of the target image. The experimental results using the Hyperion and Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) hyperspectral data demonstrated its efﬁciency.
Use of the volatile trichodiene to reduce Fusarium head blight and trichothecene contamination in wheat

Fusarium graminearum is the primary cause of Fusarium head blight (FHB), one of the most economically important diseases of wheat worldwide. FHB reduces yield and contaminates grain with the trichothecene mycotoxin deoxynivalenol (DON), which poses a risk to plant, human and animal health. The first committed step in trichothecene biosynthesis is formation of trichodiene (TD). The volatile nature of TD suggests that it could be a useful intra or interspecies signalling molecule, but little is known about the potential signalling role of TD during F. graminearum‐wheat interactions. Previous work using a transgenic Trichoderma harzianum strain engineered to emit TD (Th + TRI5) indicated that TD can function as a signal that can modulate pathogen virulence and host plant resistance. Herein, we demonstrate that Th + TRI5 has enhanced biocontrol activity against F. graminearum and reduced DON contamination by 66% and 70% in a moderately resistant and a susceptible cultivar, respectively. While Th + TRI5 volatiles significantly influenced the expression of the pathogenesis‐related 1 (PR1) gene, the effect was dependent on cultivar. Th + TRI5 volatiles strongly reduced DON production in F. graminearum plate cultures and downregulated the expression of TRI genes. Finally, we confirm that TD fumigation reduced DON accumulation in a detached wheat head assay.
