A Conceptual Framework of Mobile Payment System Adoption and Use in Southeast Asia

The research aims to investigate the factors affecting consumers' adoption and use of Mobile Payment Systems (MPS) in Southeast Asia. Extant theoretical models need to be extended to cover the unique features of mobile payment technology. A Systematic Literature Review (SLR) is conducted to analyse theoretical models utilized to predict the adoption and use of mobile payment. A total of 60 studies about adoption and use of MPS is analysed. The results of the investigations employ the Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT), and Diffusion of Innovation model (IDT). It reveals that there are inconsistencies in determinants of behavioral intention to adopt and use MPS. Among them are performance expectancy, effort expectancy, and social influence. The review also unveils the use of other determinants to predict behavioral intention to adopt and use MPS, such as perceived security, perceived risks, perceived trust, attitude, and financial incentives to lure new users. The researchers propose a conceptual framework for MPS adoption and use that includes four moderators: gender, age, educational level, and income level. The research contributes to the theory and practice by explicating relevant factors predicting behavioral intention to adopt and use mobile payment in the ASEAN region. Moreover, the SLR offers opportunities for future investigations.
Compressed Sensing Combination with 3D-TOF-MRA with Recalled-Echo Imaging with 2-Point Dixon in Artery Patency Using 3D-T1 Gradient by Flow Diverters: Evaluation of Parent Follow-up of Intracranial Aneurysms Treated

BACKGROUND AND PURPOSE: MRA assessment of parent artery patency after ﬂ ow-diverter placement is complicated by imaging artifacts produced by these devices. The purpose of this study was to assess the accuracy of liver acquisition with volume acceler- ation-ﬂ ex technique (LAVA-Flex) MRA in combination with 3D-TOF with HyperSense MRA for the evaluation of parent vessel status after intracranial ﬂ ow-diverter placement. MATERIALS AND METHODS: Fifty-six patients treated by ﬂ ow diversion and followed with both DSA and 3T MRA between November 2020 and August 2021 were included. All patients were evaluated for parent artery patency using the same imaging protocol (DSA, noncontrast MRA including 3D-TOF with HyperSense and LAVA-Flex, and contrast-enhanced MRA, including time-resolved imaging of contrast kinetics MRA and delayed contrast-enhanced MRA). RESULTS: With DSA as a criterion standard to evaluate the patency of the parent vessel, noncontrast MRA had a good speci ﬁ city (0.83) and positive predictive value (0.65), better than contrast-enhanced MRA (0.55 and 0.41, respectively). Both had excellent sensitivity and negative predictive value: noncontrast MRA, 0.93 and 0.97, respectively; contrast-enhanced MRA, 0.93 and 0.96, respectively. Speci ﬁ city and positive predictive value tended to be lower for patients treated with additional devices than for those treated with ﬂ ow diverters exclusively and for patients treated with a speci ﬁ c type of ﬂ ow diverter. CONCLUSIONS: Noncontrast MRA can be used for noninvasive follow-up of
Comptes Rendus Géoscience Sciences de la Planète

The theoretical relationships between simple and cross-covariances of the transmissivity and the hydraulic head, deduced from the linearisation of the flow equation are used for cokriging transmissivity field with data from one then two quasi steady-state flows. First a non-exhaustive historical review of geostatistical modelling based on flow equations in a simplified case is given. Then original results show that the estimation of the logtransmissivity by cokriging with head data from two flows is improved compared with the case of head data from a single flow. The estimation in the presence of a transmissivity barrier is thoroughly investigated. Practical conclusions are drawn and perspectives based on the recent numerical variogram are proposed.

Plant Succession Following Control of Western Juniper (Juniperus occidentalis) with Picloram

A 7-yr study was conducted to investigate successional dynamics of herbaceous vegetation after control of western juniper (Juniperus occidentalis Hook.) trees with picloram (4-amino-3,5,6-trichloropicolinic acid) pellets. Downy brome (Bromus tectorum L. # BROTE) rapidly dominated areas under dead tree canopies with an accompanying yield increase from almost none to about 1400 kg/ha within 4 yr after treatment. In the interstitial zone between tree canopies, a dramatic shift in herbaceous species occurred with tree control. Annual broadleaf species decreased, downy brome increased, and medusahead [Taeniatherum asperum (Sim.) Nevski # ELYCM] gradually became dominant. Total yield of herbaceous vegetation in the interstitial zone increased dramatically after picloram treatment, especially where few shrubs occurred. Available soil moisture, litter accumulation and decay after picloram treatment, and N in the surface layer of the soil affected responses of herbaceous vegetation, especially under dead tree canopies. Responses of annual weedy species to western juniper control emphasize the need for comprehensive manipulation of all components of the vegetation when range improvement is attempted.
Short Communication: Correlation and regression among rice panicle branches traits

Abstract. Hastini T, Suwarno WB, Ghulamahdi M, Aswidinnoor H. 2019. Short Communication: Correlation and regression among rice panicle branches traits. Biodiversitas 20: 1140-1146. Panicle was a very important organ in rice since the grains are developed from the panicle branches. This study aimed to find out the information about the relationship among rice panicle branching traits using correlation and regression analysis. The trial was conducted at the IPB Research Station, Babakan, Bogor, Indonesia from December 2015 until April 2016. Twenty genotypes of lowland rice were used as treatments with three replications and arranged in a completely randomized design. The panicle branches traits were observed. The result showed that there was positively and a highly significant relationship among the panicle branches traits in general. Analysis using linear regression revealed that, in general, the total grains number per panicle showed the linear relationships with other traits, and only total grains number per panicle vs tertiary branches number, total grains number per panicle vs grains number of tertiary panicle branch, and total grains number per panicle vs the number of secondary branches per panicle branch showed the quadratic relationship. Among all rice panicle branching traits, the secondary panicle branches number had the highest contribution to the total grains number per panicle.
When and How Ram Pressure Stripping in Low-mass Satellite Galaxies Enhances Star Formation

We investigate how a satellite's star formation rate (SFR) and surviving gas respond to ram pressure stripping (RPS) in various environments. Using a suite of high-resolution wind tunnel simulations with radiative cooling, star formation, and supernovae feedback, we model the first infall orbit of a low-mass disk galaxy (M * = 109.7 M ⊙) in different host halos, ranging from Milky Way–like to cluster hosts. When the ram pressure is moderate, we find that the stripping satellite shows an enhanced SFR relative to the isolated control case, despite gas loss due to stripping. The SFR enhancement is caused, not directly by compression, but by ram-pressure-driven mass flows, which can increase the dense gas fraction in the central disk regions. The spatially resolved star formation main sequence and Kennicutt–Schmidt relations in our simulations are consistent with recent findings of the VERTICO and GASP surveys. Our results predict the environmental signals of RPS in future multiwavelength, high-angular resolution observations: the star formation and gas surface densities will be centralized, and symmetrically enhanced within the stripping radius.
Flow over a step cylinder using partially-averaged Navier-Stokes equations with application towards dynamic subsea power cables

Understanding the flow characteristics of buoyancy sections in power cable and umbilical configurations is crucial for analyzing floating offshore wind turbine systems. Buoyancy sections decouple the motions from the floater and the destination point to ensure the integrity of the system. Using accurate drag coefficients in their design is essential, as they significantly impact the overall behavior of the configuration. Therefore, Computational Fluid Dynamic (CFD) analysis is performed in the present study on a single buoyancy module attached to a power cable represented by a step cylinder configuration. The Partially-Averaged Navier-Stokes (PANS) turbulence model is applied. Its accuracy is validated against experimental findings of a wall-mounted cantilever cylinder and an infinite cylinder. The numerical results reveal that the larger diameter cylinder (LDC) section reduces the drag experienced by the smaller diameter cylinder (SDC) section near the junction. The LDC has a sharp, chamfered, and filleted edge replicating the various shapes of buoyancy modules. The edge design of the LDC affects the drag forces and flow patterns. The SDC has an 8% lower drag coefficient in the fillet edge case than the sharp edge case. The drag coefficient is 3.5% lower for the LDC in the filleted edge case than the sharp edge case. The sharp edge causes a significant separation of the fluid upstream of the SDC. However, this separation is notably reduced when the LDC has a chamfered or filleted edge. Detailed drag coefficients for buoyancy section analysis of power cable configurations have been deduced from the presented results.
Resolving Carrier-Phase Ambiguities On The Fly, At More Than 100 km From Nearest Reference Site, With The Help Of Ionospheric Tomography

In this paper we address the question of how to resolve GPS carrier phase ambiguities precisely and quickly, when the rover is more than 100 kilometers from the nearest reference site, in order to obtain sub-decimeter (r.m.s.) position in real-time (and, by implication, in postprocessing). To do this reliably, ionospheric refraction has to be corrected very accurately. For distances of up to a few hundred kilometers, dual-frequency GPS data from permanent control stations may be used to obtain the necessary ionospheric refraction information. The ionosphere over the area served by the stations has to be mapped using their carrier phase data, also in real-time, by computed ionospheric tomography. The resulting map is used to produce information that is transmitted to the user, along with range and time corrections. The user can then calculate very precise corrections for ionospheric refraction at the location of the roving receiver. After a successful preliminary test using 1997 data from the core control stations of the CATNET network in Catalunya, (Catalonia) Spain, a second test involving those, as well as a road vehicle, was conducted in March of 1999, at a distance of 116 km from the nearest reference station. The data were processed after the test, but simulating a realtime analysis. As reported here, repeated attempts at resolving all the L1 and L2 ambiguities proved successful over a total period of two hours.
Variability in Protoplanetary Nebulae. X. Multiyear Periods as an Indicator of Potential Binaries

New observations are presented of four evolved objects that display long, multiyear variations in their light curves. These are interpreted as good evidence of their binary nature, with the modulation caused by the barycenter motion of the evolved star resulting in a periodic obscuration by a circumbinary disk. Although protoplanetary nebulae (PPNe) commonly possess bipolar nebulae, which are thought to be shaped by a binary companion, there are very few PPNe in which a binary companion has been found. Three of the objects in this study appear to be PPNe, IRAS 07253−2001, 08005−2356, and 17542−0603, with long periods of 5.2, 6.9, and 8.2 yr, respectively. The binary nature of IRAS 08005−2356 has recently been confirmed by a radial velocity study. Two samples, one of PPNe and the other of post-AGB star candidates, are investigated for further evidence on how common is a long-period light-curve variation. Both samples suggest such light-curve variations are not common. The fourth object, IRAS 20056+1834 (QY Sge), is an obscured RV Tau variable of the RVb subclass, with a long period of 3.9 yr and pulsation periods of 102.9 and 51.5 days. The period of this object is seen to vary by 2%. Evidence is presented for a recent mass ejection in IRAS 17542−0603.
Assessing the phenolic content and antimicrobial properties of Cinnamomum porrectum, Dioscorea bulbifera, and Tristaniopsis whiteana extracts for anticaries agent

In this study, we have assessed the phenolic content and antimicrobial properties of three plants (Cinnamomum porrectum, Dioscorea bulbifera, and Tristaniopsis whiteana) against S. mutans and S. sobrinus, bacteria known to contribute to dental caries. The study focused on investigating the antimicrobial properties using the nutrient broth dilution method. Phytochemical screeing was performed using quantitative analysis, which revealed the total polyphenol and total tannin content in the studied plants. The results of the antimicrobial activity test prove that extracts from T. whiteana exhibibited strong inhibition activity against S. sobrinus and S. mutans. The inhibition rates were measured at 76.3% and 72.18%, repectively. These findings suggest that extracts from T. whiteana have the potential to be effective antimicrobial agent against these bacteria. Based on these results, the study concluded that the tested plant extracts have proven antimicrobial efficacy, supporting their potential use as natural antimicrobial. The study highlighted T. whiteana as the promising candidate among tree plants in this study, by demonstrating strong potential as an anticaries agent against microorganisms responsible for dental caries. Furthermore, research and exploration of these plant extracts may supply valuable insight into their mechanisms of action and their potential application in the field of medicine.
Material characterization of EN AC-Al Si12CuNiMg alloy in stress relaxation and creep conditions

Al–Cu–Mg alloys are widely used in various applications, especially engine components, where it is subjected to elevated temperatures during operation. Prolonged exposure of these components to elevated temperatures gradually leads to creep and relaxation phenomena. This study aims to investigate the effects of temperature on stress relaxation and creep behavior of the aluminum-silicon alloy EN AC-Al Si12CuNiMg. Furthermore, this study evaluates the effect of temperature on the rheological model parameters of this alloy. Experimental tests were conducted to investigate the stress relaxation and creep behavior of this alloy at different temperatures of 150°C, 250°C, and 350°C. The rheological model parameters were then determined from the obtained experimental data. The Standard Linear Solid Model (SLSM) was used to fit the stress relaxation and creep curves obtained from the experiment. Overall, the results indicate that increasing temperature significantly affects the stress relaxation and creep behavior of the investigated alloy, with higher temperatures leading to increased relaxation and creep rates. Additionally, the rheological model parameters of the alloy were found to vary with temperature.
Estimation of channel and flood plain roughness using HEC-RAS model: A case study of the Veseočica River, Bosnia and Herzegovina

Modeling flow in open channels is essential for determining channel capacity and predicting flood events. The key segment for creating flood hazard and risk maps is a high-quality hydraulic model of the flow in the main bed with its tributaries. Several software packages have been developed for hydrodynamic simulations of flood events. In addition to the geometric characteristics of the watercourse, the equations of a one-dimensional flow model include a parameter that connects all influences that provide resistance to the flow of water. Determining the roughness of a natural channel is one of the most demanding procedures for the development of hydraulic models. Therefore, it is necessary to calibrate and validate the Manning coefficients of the channel roughness using simulation models. In the present study, the estimation of channel and floodplain roughness for the Veseočica River in Bosnia and Herzegovina was performed using the HEC-RAS hydrodynamic model. After calibration and verification of the model, flood hazard maps were created for flood waves with return periods of 20, 100, and 500 years. ArcGIS and HEC-GeoRAS software tools were used to create the flood risk maps.
Tolerance to heated egg in egg allergy: Explanations and implications for prevention and treatment

Abstract Hen's egg allergy is the second most frequent food allergy found in children. Allergic symptoms can be caused by raw or heated egg, but a majority of egg‐allergic children can tolerate hard‐boiled or baked egg. Understanding the reasons for the tolerance towards heated egg provides clues about the molecular mechanisms involved in egg allergy, and the differential allergenicity of heated and baked egg might be exploited to prevent or treat egg allergy. In this review, we therefore discuss (i) why some patients are able to tolerate heated egg; by highlighting the structural changes of egg white (EW) proteins upon heating and their impact on immunoreactivity, as well as patient characteristics, and (ii) to what extent heated or baked EW might be useful for primary prevention strategies or oral immunotherapy. We describe that the level of immunoreactivity towards EW helps to discriminate patients tolerant or reactive to heated or baked egg. Furthermore, the use of heated or baked egg seems effective in primary prevention strategies and might limit adverse reactions. Oral immunotherapy is a promising treatment strategy, but it can sometimes cause significant adverse events. The use of heated or baked egg might limit these, but current literature is insufficient to conclude about its efficacy.
Aquaponics vs. hydroponics: production and quality of lettuce crop.

Aquaponics is an environmental-friendly production system due to its full reuse of waste and nutrients. The research, carried out at the Experimental Farm of the University of Tuscia, compared summer yields of two romaine lettuce crops (Lactuca sativa L. ‘Integral’) grown on aquaponic and hydroponic floating systems. For the hydroponic treatment a nutritive solution of 1.7 dS m-1 and pH 5.5 supported plant growth. For the aquaponic system two treatments under different fish densities supplied nutrients at different concentrations. Every aquaponic treatment consisted of 3 independent 250-L tanks stocked with Nile tilapia (Oreochromis niloticus L.). Each fish tank fed a 1.5 m2 floating system under a 20 plant m-2 density. For the first crop 110 g and 24 g tilapia were stocked at system setup respectively under a low (5 kg m-3) and high (8 kg m-3) density and supplied nutrients with an electrical conductivity (EC) of 0.4 and 0.6 dS m-1. For the second crop 168 g and 90 g tilapia respectively stocked under a low (6 kg m-3) and high (20 kg m-3) stocking density raised EC levels to 0.5 and 1.0 dS m-1. Production of 2.8 kg m-2 from the first hydroponic crop was similar to the 2.7 kg m-2 assessed in the high density aquaponic treatment. Conversely the 2.3 kg m-2 measured in the low density treatment was smaller. For the second trial no differences were noticed between the 6.0 kg m-2 measured in the hydroponic system and the 5.7 and 5.6 kg m-2 assessed in the high and low-density aquaponic treatments, respectively. Nevertheless different nutrient concentrations in water affected plant mineral composition. Aquaponic leaves were poorer in phosphorus but richer in calcium, potassium magnesium and sodium.
Species Distribution Model for the Asian Tapir and Vegetation Characteristics of Batang Gadis National Park, North Sumatra, Indonesia

The Asian tapir is a primitive mammal whose habitat is heavily fragmented due to human activities. Studies on the Asian tapirs in Sumatra are very few, thereby basic information for developing tapir conservation programmes is limited. This study aimed to develop the species distribution model to map the potential distribution of tapirs in Batang Gadis National Park (BGNP), investigate the characteristic of tapir habitat, and identify tapir feed plants around BGNP. The model was developed using the Maximum Entropy (Maxent) approach, based on the existing information on tapir occurrence in BGNP and environmental variables. Vegetation characteristics in different land cover (primary forests, secondary forests, and open fields) were investigated using the strip transect method. This study found that zonal classification, temperature and precipitation have the greatest percentage contribution to the model. The model estimated that around 24.45% of BGNP areas are suitable for tapir habitat, and tapirs distribute near community gardens. Our results also showed that plant diversity at study sites was categorised as moderate-high. About 23 plant species dominated by the Moraceae family were identified as feed plants for tapirs. In developing tapir conservation programmes, BGNP management needs to consider tapir distribution that is closed to community gardens. We propose BGNP to enrich feed plants in open fields of the wilderness and traditional zones; reduce the canopy cover in the wilderness and utilisation zones to stimulate the growth of feed plants; facilitate local people to live harmoniously with tapirs; involve local communities in tapir conservation programmes; encourage local communities to plant non-palatable crops for tapirs; and provide a compensation scheme.
Identifying spatial variability and complexity in wetland vegetation using an object-based approach

ABSTRACT Coastal wetland vegetation is complex in form and function. Accurately mapping the spatial variation of vegetation complexity within these ecosystems is important for identifying areas of high conservation value that provide essential ecosystem services. In this study we delineate wetland vegetation, particularly mangrove and saltmarsh, to a vegetative morphological level that identifies spatial complexity in vegetation structure. This was achieved by integrating light detection and ranging (Lidar) and aerial imagery with an object-based approach. The results demonstrate that this is an effective methodology to identify vegetation complexity, with all study sites having greater than 90% classification accuracy. These high classification accuracies were underpinned by the use of Lidar data that provide detailed structural information about vegetation that is not captured with aerial imagery. This research highlights the importance of identifying spatial variability in vegetation structure when considering the value of coastal ecosystems and the services they provide.
