Sharing asymmetric Einstein–Podolsky–Rosen steering with projective measurements

Published: August 2024

Abstract
Recently, both global and local classical randomness-assisted projective measurement protocols have been employed to share Bell nonlocality of an entangled state among multiple sequential parties. Unlike Bell nonlocality, Einstein–Podolsky–Rosen (EPR) steering exhibits distinct asymmetric characteristics and serves as the necessary quantum resource for one-sided device-independent quantum information tasks. In this work, we propose a projective measurement protocol and investigate the shareability of EPR steering with steering radius criterion theoretically and experimentally. Our results reveal that arbitrarily many independent parties can share one-way steerability using projective measurements, even when no shared randomness is available. Furthermore, by leveraging only local randomness, asymmetric two-way steerability can also be shared. Our work not only deepens the understanding of the role of projective measurements in sharing quantum correlations but also opens up a new avenue for reutilizing asymmetric quantum correlations.

Abstract
Magnetic films with low Gilbert damping are crucial for magnonic devices, which provide a promising platform for realizing ultralow-energy devices. In this study, low Gilbert damping and coercive field were observed in Bi/In-doped yttrium iron garnet (BiIn:YIG) thin films. The BiIn:YIG (444) films were deposited onto different substrates using pulsed laser deposition. Low coercivity (<1 Oe) with saturation magnetization of 125.09 emu/cc was achieved along the in-plane direction of BiIn:YIG film. The values of Gilbert damping and inhomogeneous broadening of ferromagnetic resonance in BiIn:YIG films were obtained to be as low as 4.05 × 10−4 and 5.62 Oe, respectively. In addition to low damping, the giant Faraday rotation angles (up to 2.9 × 104 deg/cm) were also observed in the BiIn:YIG film. By modifying the magnetic structure and coupling effect between Bi3+ and Fe3+ of Bi:YIG, doped In3+ plays a key role on variation of the magnetic properties. The low damping and giant Faraday effect made the BiIn:YIG film an appealing candidate for magnonic and magneto-optical devices.

Abstract
Detectors were developed for detecting irradiation in the short-wavelength ultraviolet (UVC) interval using high-quality single-crystalline α-Ga2O3 films with Pt interdigital contacts. The films of α-Ga2O3 were grown on planar sapphire substrates with c-plane orientation using halide vapor phase epitaxy. The spectral dependencies of the photo to dark current ratio, responsivity, external quantum efficiency and detectivity of the structures were investigated in the wavelength interval of 200−370 nm. The maximum of photo to dark current ratio, responsivity, external quantum efficiency, and detectivity of the structures were 1.16 × 104 arb. un., 30.6 A/W, 1.65 × 104%, and 6.95 × 1015 Hz0.5·cm/W at a wavelength of 230 nm and an applied voltage of 1 V. The high values of photoelectric properties were due to the internal enhancement of the photoresponse associated with strong hole trapping. The α-Ga2O3 film-based UVC detectors can function in self-powered operation mode due to the built-in electric field at the Pt/α-Ga2O3 interfaces. At a wavelength of 254 nm and zero applied voltage, the structures exhibit a responsivity of 0.13 mA/W and an external quantum efficiency of 6.2 × 10−2%. The UVC detectors based on the α-Ga2O3 films demonstrate high-speed performance with a rise time of 18 ms in self-powered mode.
Kelvin’s circulation pinch theory in magnetized plasma turbulence
Authors: Guo Z.B. 
Published: August 2024

Abstract
In this study, we present a topological transport theory–the turbulence pinch in magnetized plasmas–by utilizing the generalized Kelvin’s circulation as a constraint. An exact nonlinear relation between the Kelvin’s circulation pinch velocity and the turbulence vorticity flux has been derived. The flux-driven feature of the circulation pinch suggests an approach to non-locally control particle pinch velocity through varying boundary conditions. Due to its ubiquity and robustness, this theory provides a promising mechanism to produce an up-gradient particle transport.

Abstract
Satellite launches are critical amid increasing demands for advanced services. Rising costs urge innovation in engineering. Enhancing satellite structural integrity during launches is crucial due to intense vibrations. Topology optimisation and additive manufacturing converge as promising solutions. Topology optimisation uses mathematical techniques to iteratively improve structures by reducing mass while enhancing attributes like load capacity. This field, active for about three decades, employs continuum and discrete algorithms to optimise structures. Recent trends show optimised structures through topology optimisation and additive manufacturing promise cost-effective and high-performance solutions. This study aims to extensively review topology optimisation methods, specifically focusing on satellite structures, to shape future developments within the years to come.

Published: August 2024

Abstract
The detection of combustion gases such as carbon monoxide (CO) and fuel leaks is a concern in regard to aeronautical safety and has led to the development of semiconductor sensors. The focus of this work is the detection of CO within commercial aircraft using a thin film of nickel oxide (NiO) as the sensing element. The NiO phase was synthesized using the sol-gel method using a modification of the procedures proposed by N. Talebian and B. Pejova. Microstructural characterization of the NiO thin film was performed using scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Optical analysis was carried out using diffuse reflectance (UV-VIS) spectroscopy. The results showed that the NiO thin film was homogeneous and composed of nodular nanoparticles with size between 10 and 15 nm and thickness of 75 nm. The band gap value was 3.3 eV, which is consistent with p-type semiconductors. The sensitivity of the devices was determined by means of the static environment method. The best operation temperature was 200°C for the device with 100-µm spacing between tracks, which gave a response time of 165 seconds and recovery time of 212 seconds according the results of a flow-through method. The device with this track spacing is ideal for CO detection at 50 ppm, at which the first symptoms of intoxication appear in humans inside commercial aircraft.

Published: August 2024

Abstract
This paper describes the application of light emitting diodes (LEDs) as light detectors for remote sensing systems, used for the measurement of normalized differential vegetation index, one of the most common parameters monitored by these systems. The light intensity measurement was carried out through correlation of discharge time of photocapacitance of LEDs, and the performance of this configuration was compared with the same LEDs used as detectors in photovoltaic mode. One measurement system was implemented for each configuration of LEDs, using the STM32F401CBU6 microcontroller.
The normalized differential vegetation index was measured in samples of liquid suspensions of microalgae Spirulina platensis with different biomass concentrations. The measurements were taken at an outdoor location and under sunlight illumination.
The results obtained with measurement of normalized differential vegetation index through photocapacitance discharge effect demonstrated that this is an effective technique with an improved repeatability in measurement, in comparison with photovoltaic mode of LEDs used as detectors.

Published: August 2024

Abstract
The agricultural sector is a vital component of Indonesia’s economy. However, agricultural production in Jawa Barat, particularly in horticulture, is facing various sustainability challenges. It is crucial to adopt a sustainable approach to agricultural production. This study aims to develop the Balanced Scorecard (BSC) framework to enhance the sustainability of horticultural production in Jawa Barat, using the FAO Sustainability Assessment of Food and Agriculture (SAFA) Framework. A focus group discussion (FGD) was conducted with 68 horticultural farmers representing different regions and horticultural commodities in Jawa Barat. During the FGD, participants rated their familiarity with SAFA Framework indicators and assessed their importance. Frequency analysis was performed on the collected data to determine familiarity and importance levels and correlation analysis using the R method. This research reveals that indicators related to community investment, biodiversity, and renewable energy received lower recognition, suggesting a need for increased emphasis in these areas. The correlation analysis revealed a positive link between Finance and Customer dimensions, highlighting the importance of financial management for customer satisfaction. Addressing these findings will help enhance sustainability and bridge gaps in horticultural practices in Jawa Barat. The findings will support sustainable agricultural practices, enhance decision-making, and promote the long-term viability of the horticultural sector

Abstract
Preference is one part of consumer response in determining the choice of product to be used. This study aims to determine millennials’ preferences for processed sago noodle products using natural colors from dragon fruit, turmeric, and moringa leaves. The research method uses quantitative descriptive analysis data. Data was collected using questionnaires. The data observed in this study are the characteristics of respondents, color, aroma, taste, and texture of sago noodles. The collected data was analyzed descriptively and through chi-square analysis. The results showed the response of the millennial generation in taking part in trials of processed sago products is very high. This is proven by the willingness of 72% of respondents in the age range of 19 – 24 years, included in the millennial generation category, and only 4% of respondents who are in the age range of more than 50 years. As many as 44% of respondents had consumed processed sago bagea (traditional cake), followed by 36% kapurung (traditional food), 4% sago meatballs, and 4% sago noodles. Processed sago products are no longer foreign to the millennial generation. Only 4% of respondents had ever consumed sago noodles because sago noodles are a new food in South Sulawesi. The millennial generation’s preference for developing local food products processed from sago is very high, both newly developed products such as sago noodles, and old processed products such as bagea, kapurung and sago meatballs. From the organoleptic results of sago noodles from several treatments with the addition of natural coloring, it is known that sago noodles using coloring from dragon fruit extract are the most preferred, followed by real sago noodles, then sago noodles using turmeric coloring and finally sago noodles using colouring from moringa leaf extract.

Abstract
This study was conducted in five villages in Bunga Raya District (Kemuning Muda, Bunga Raya, Tuah Indrapura, Jayapura, and Buantan Lestari), the rice production centers of Siak Regency, Riau. The research location was selected based on the largest percentage of rice field area. The research was conducted from January to July 2019. This research aims to determine sustainable lowland rice farming management variables for future lowland rice farming development in Bunga Raya District, Siak Regency. Purposive sampling was used to choose the 82 sample farmers, who were selected using the Slovin equation. The respondents are selected with a margin of error of 7% of the total population of farmer families. Data was gathered through the use of interview techniques, questionnaires, and field observations. Multi-dimensional scaling (MDS) was used to analyze sustainable rice farming management factors after updating the Rapfish program. According to the findings of the sustainability study of 42 studied variables, 12 of them show sensitivity. Five of the ten stakeholder needs attributes were examined to provide sensitivity. The combined analysis of current prospective sustainability with stakeholders yielded five attributes determining factors for the sustainability of lowland rice farming in Bunga Raya: land conversion, participation in training/extension services, pesticide use, agro-tourism potential, and farmer capital availability. Another recommendation that policy makers need to consider, which is no less important, is to always preserve the rice field ecosystem by developing natural and human resources, so that increasing the welfare of farmers and increasing regional income can be achieved.

Abstract
Expansion of sugarcane in East Java continue to be implemented in addition to intensification to increase sugarcane production in East Java, including expansion to Blitar Regency. This study aims to determine the rainfall distribution in areas suitable for sugarcane cultivation in Blitar Regency, East Java. This study was done in 2022 by combining a sugarcane land suitability map in Blitar Regency from the Indonesian Center for Agricultural Land Resources Research and Development and an annual isohyet map. Maps showing the rainfall distribution that the further north in Blitar the more elevation and rainfall and decreasing to the south. Annual rainfall distribution of 1500-2000 mm and 2000-2500 mm in the areas of moderately and marginally suitable for sugarcane covered total area of 25,918.59 ha and 22,689.90 ha or 15.83% and 13.86% of the total existing land area, respectively. When expanding sugarcane development, it is essential to consider the rainfall distribution along with the spatial distribution of land. Therefore, field trials are needed in each zoning to determine the productivity level of sugarcane and sugar. Complementing the spatial distribution of land for sugarcane with the rainfall distribution in each zone is important to identify yield potential for each suitability class.

Published: August 2024

Abstract
Rice (Oryza sativa L.) serves as a staple food for over half of the world’s population, and its production is vital for global food security. However, the increasing demand for rice is threatened by the rising occurrence of drought stress, driven by erratic rainfall patterns attributed to unpredictable global climate. Drought stress can significantly affect rice at various growth stages, with seed germination being particularly vulnerable due to reduced water intake. Direct Seeded Rice (DSR), an alternative planting technology, offers water efficiency and cost savings but faces challenges like poor stand establishment. Seed priming, a technique that enhances seedling emergence and early growth, has proven to be a practical approach for improving rice tolerance under suboptimal conditions, including drought. The present article is intended to discuss (i) the mechanism and benefits of seed priming, (ii) seed priming techniques, potential agents, and effectiveness factors, (iii) the mechanism of seed priming to improve drought tolerance, (iv) challenges and opportunities, to promote the seed priming strategy as a future, cost-effective research tool to increase rice yield and productivity under drought stress.

Abstract
The incompatibility of N, P, and K rates for maize plants causes a decrease in plant productivity and farmer income. Therefore, there is a need for appropriate N, P, and K fertilizer recommendations based on agroecosystems that farmers can apply. This research aims to obtain location-specific N, P, and K fertilization recommendations for maize based on the agroecosystem in Jeneponto Regency, South Sulawesi. This research was conducted in Jeneponto District, South Sulawesi, from March to October 2021. The research used a survey method adapted to the questions in the Nutrient Expert (NE) program form. The research showed that the optimum fertilizer recommendation for maize in Jeneponto District was 170 – 190 kg N ha−1, 30 – 60 kg P2O5 ha−1, and 33 – 63 kg K2O ha−1, with a 9 – 10 t/ha yield. Using these recommendations, they will gain a higher profit and R-C ratio than the farmer’s existing fertilization, namely, a profit of RP. 30,499,400 (Rp. 30,276,000 – 30,697,000) with an R-C ratio of 4.05 (3.96 – 4.13), whereas if using existing fertilization at the farmer level, they will gain a profit of Rp. 19,397,000 (Rp. 14,215,000 – Rp. 25,735,000) with an R-C ratio of 2.20 (1.81 – 2.75).

Published: August 2024

Abstract
Effective food preservation methods encompass a range of approaches, among which drying stands out for its convenience in storage and distribution. The drying process and subsequent storage of food, however, are significantly influenced by environmental conditions. To address this, the utilization of activated carbon derived from renewable biomass sources emerges as a sustainable solution for moisture sorption applications. This research delves into optimizing the production of activated carbon from cajuput biomass, harnessing its exceptional desiccant properties through the Taguchi method. The study rigorously investigates crucial parameters, namely carbonization temperature (400, 600, 800 °C), carbonization time (1, 2, 3 hours), NaOH concentration (1, 2, 3%), and impregnation time (1, 2, 3 hours). Employing a two-step approach involving carbonization followed by chemical activation with NaOH, the impact of these variables on the activated carbon’s moisture adsorption capacity is comprehensively evaluated. Remarkably, the optimized conditions of carbonization temperature at 400 °C, carbonization time of 3 hours, NaOH concentration of 3%, and impregnation time of 3 hours yield a maximum moisture adsorption capacity of 0.4076 g/g. These findings emphasize the transformative potential of cajuput biomass as a valuable feedstock for producing activated carbon, endowed with remarkable moisture sorption attributes. This cajuput-derived activated carbon presents an alternative desiccant for efficient moisture adsorption in the food drying process and optimal moisture control during food product storage.
