Published: August 2024

Abstract
High-precision polar motion prediction is of great significance for deep space exploration and satellite navigation. Polar motion is affected by a variety of excitation factors, and nonlinear prediction methods are more suitable for polar motion prediction. In order to explore the effect of deep learning in polar motion prediction. This paper proposes a combined model based on empirical wavelet transform (EWT), Convolutional Neural Networks (CNN) and Long Short Term Memory (LSTM). By training and forecasting EOP 20C04 data, the effectiveness of the algorithm is verified, and the performance of two forecasting strategies in deep learning for polar motion prediction is explored. The results indicate that recursive multi-step prediction performs better than direct multi-step prediction for short-term forecasts within 15 days, while direct multi-step prediction is more suitable for medium and long-term forecasts. In the 365 days forecast, the mean absolute error of EWT-CNN-LSTM in the X direction and Y direction is 18.25 mas and 15.78 mas, respectively, which is 23.5% and 16.2% higher than the accuracy of Bulletin A. The results show that the algorithm has a good effect in medium and long term polar motion prediction.

Abstract
The observations of the Aquila Rift cloud complex at 23.708 and 115.271 GHz made using the Nanshan 26 m radio telescope and the 13.7 m millimeter-wavelength telescope are presented. We find that the CO(1 − 0) gas distribution is similar to the NH3 gas distribution in the Aquila Rift cloud complex. In some diffusion regions characterized by CO, we identified several dense clumps based on the distribution of detected ammonia molecular emission. Through the comparison of spectral line parameters for NH3, 13CO, and C18O, our study reveals that the line center velocities of the NH3, 13CO, and C18O lines are comparable and positively correlated, indicating that they originate from the same emission region. No significant correlation was identified for other parameters, including integrated intensity, line widths, main beam brightness temperature, as well as the column densities of NH3, 13CO, and C18O. The absolute difference in line-center velocities between the 13CO and NH3 lines is less than both the average line width of NH3 and that of 13CO. This suggests that there are no significant movements of NH3 clumps in relation to their envelopes. The velocity deviation is likely due to turbulent activity within the clumps.

Abstract
As part of the commissioning work at the linear electron accelerator LINAC-200 (JINR), we conducted experiments to study the characteristics of a pulsed neutron source obtained by irradiating a converter target with a 140 MeV electron beam. To estimate neutron source parameters and neutron energy spectra in lead and tungsten targets with different sizes numerical simulations were performed. Additionally, we have conducted experiments to measure the energy spectra of neutrons and gamma rays using high-resolution time-of-flight method. It has been found that the ratio of integral estimates between the calculated and average measured neutron yields (for tungsten and lead targets) did not exceed 30%. The fluence of resonant and thermal neutrons in the target is estimated at 2.8×1013 neutrons per second, which corresponds to the requirements for modern pulsed neutron sources.
Spectral X-ray computed tomography image denoising using weighted local regression and noise-insensitive feature dimensionality reduction

Published: August 2024

Abstract
This study introduces a novel denoising method for spectral
X-ray computed tomography (CT) images using weighted local
regression (WLR). The proposed method exploits the common structural
information present across different energy bins. Denoised pixel
intensities of a certain energy bin are estimated using the
intensities of the other energy bins via WLR. Denoising is achieved
by applying a WLR model to the noisy pixel intensities of all energy
bins, excluding the target bin, which obtains approximate noise-free
intensities for the target energy bin. The performance of our
approach was assessed using synthetic spectral X-ray CT images
produced using a Monte Carlo photon simulator called the Electron
Gamma Shower 5 (EGS5). Both qualitative and quantitative evaluations
demonstrated that our approach effectively reduced noise across all
energy bins while maintaining image sharpness. Comparisons with
common denoising methods demonstrate the effectiveness of the
proposed method.
Automated characterisation and operational insights of superconducting travelling wave parametric amplifiers: unveiling novel behaviours and enhancing tunability
Authors: Wood S. , Klimovich N. , Tan B.-K. 
Published: August 2024

Abstract
Superconducting travelling wave parametric amplifiers
(TWPAs) exhibit great promise across various applications, owing to
their broadband nature, quantum-limited noise performance, and
high-gain operation. Whilst their construction is relatively simple,
particularly for thin-film-based TWPAs, challenges such as the
requirement for an extremely long transmission line, current
fabrication limitations, and their sensitivity to fabrication
tolerances, mean that their optimal operating conditions often
differ from those anticipated during the design stage. As a result,
manual fine-tuning of numerous operational parameters becomes
necessary to recover optimal performance; a process that is both
labour-intensive and time-consuming. This paper introduces an
automated methodology designed to significantly accelerate the
characterisation of a TWPA by several orders of magnitude without
requiring human intervention. Additionally, we have developed
metrics to condense the multitude of measured frequency responses of
the TWPA, obtained in data cube form, into an easily-understandable
format for further scientific interpretation. To demonstrate the
efficacy and speed of our methodology, we utilise an existing NbTiN
(niobium titanium nitride) TWPA as an example. This showcases the
capability of our approach to unveil both broad- and fine-scale
behaviours of the device, highlighting the importance of an
automated experimental setup for the in-depth investigation of TWPAs
for future developments.
The public use of early-stage scientific advances in carbon dioxide removal: a science-technology-policy-media perspective
Authors: Tripodi Giorgio , Lillo Fabrizio , Mavilia Roberto , Mina Andrea , Chiaromonte Francesca , Lamperti Francesco 
Published: August 2024

Abstract
While Carbon Dioxide Removal (CDR) solutions are considered essential to meet Paris Agreement objectives and curb climate change, their maturity and current ability to operate at scale are highly debated. The rapid development, deployment, and diffusion of such methods will likely require the coordination of science, technology, policy, and societal support. This article proposes a bibliometric approach to quantify the public use of early-stage research in CDR. Specifically, we employ generalized linear models to estimate the likelihood that scientific advances in eight different carbon removal solutions may induce (i) further production of scientific knowledge, (ii) technological innovation, and (iii) policy and media discussion. Our main result is that research in CDR is of significant social value. CDR research generates significant, positive, yet heterogeneous spillovers within science and from science to technology, policy, and media. In particular, advances in Direct Air Capture spur further research and tend to result in patentable technologies, while Blue Carbon and Bio-energy with Carbon Capture and Storage appear to gain relative momentum in the policy and public debate. Moreover, scientific production and collaborations cluster geographically by type of CDR, potentially affecting long-term carbon removal strategies. Overall, our results suggest the existence of coordination gaps between science, technology, policy, and public support.

Published: August 2024

Abstract
The ability of pollen to enable the glaciation of supercooled liquid water has been demonstrated in laboratory studies; however, the potential large-scale effect of plants and pollen on clouds, precipitation and climate is pressing knowledge to better understand and project clouds in the current and future climate. Combining ground-based measurements of pollen concentrations and satellite observations of cloud properties within the United States, we show that enhanced pollen concentrations during springtime lead to an increase in cloud ice fraction of up to 0.1 in the temperature regime where pollen are considered to act as INP (−15

C ). We further establish the link from the pollen-induced increase in cloud ice to a higher precipitation frequency. In light of anthropogenic climate change, the extended and strengthened pollen season and future alterations in biodiversity can introduce a localized climate forcing and a modification of the precipitation frequency and intensity.
Preserving the Hermiticity of the one-body density matrix for a non-interacting Fermi gas

Published: August 2024

Abstract
The one-body density matrix (ODM) for a zero temperature non-interacting Fermi gas can be approximately obtained in the semiclassical regime through different

ℏ

-expansion techniques. One would expect that each method of approximating the ODM should yield equivalent density matrices which are both Hermitian and idempotent to any order in

ℏ

. However, the Kirzhnits and Wigner–Kirkwood methods do not yield these properties, while the Grammaticos–Voros method does. Here we show explicitly, for arbitrary d-dimensions through an appropriate change into symmetric coordinates, that each method is indeed identical, Hermitian, and idempotent. This change of variables resolves the inconsistencies between the various methods, showing that the non-Hermitian and non-idempotent behavior of the Kirzhnits and Wigner–Kirkwood methods is an artifact of performing a non-symmetric truncation to the semiclassical

ℏ

-expansions. Our work also provides the first explicit derivation of the d-dimensional Grammaticos–Voros ODM, originally proposed by Redjati et al (2019 J. Phys. Chem. Solids

Land use hierarchical mapping for delineation of groundwater potential zones in the Ba river basin using satellite imagery and GIS technology
Authors: Ba Dung Nguyen , Tuyet Minh Dang 
Published: August 2024

Abstract
The evaluation of groundwater potential is crucial for the best use and replenishment of groundwater resources, as well as for the appropriate growth and administration of a region. To study groundwater potential, it is necessary to analyze the factors that directly affect this resource. In addition to the criteria that contribute to the formation of groundwater, such as rainfall, land cover, geology, slope, etc., land use types and their infiltration capacity are also the main factors affecting the groundwater prospect. In recent years, remote sensing and geographic information systems (GIS) have emerged as the most important technologies in the field of groundwater research, which aid in determining groundwater potential. This paper presents a method to generate the land use hierarchical map based on the level of impact on the formation of groundwater in the Ba river basin using GIS technology and remote sensing. According to the classification result, the three classes of groundwater potential zones including “low”, “moderate”, “high” occupy 1.51%, 77.43%, and 21.06% of the study area respectively. The findings can be validated with the actual groundwater level at some locations that are evenly distributed throughout the basin. The obtained results indicate that there is an agreement between groundwater potential levels at each actual location and those depicted on the land use hierarchical map. The methodology utilized in this study is reliable, accurate and can be used to generate hierarchical maps of additional parameters. This paper will be a useful document for groundwater potential zoning in the study area

Published: August 2024

Abstract
The Winongan and Gondang Wetan (WGW) sub-districts in the downstream area of the Rejoso watershed in Pasuruan are characterized by predominantly agricultural land. The World Agroforestry Centre (ICRAF) initiated a conservation program in this region called Rejoso Kita during 2016-2022. This program is designed to enhance current agricultural practices through sustainable methodologies tha effectively introduced in 12 villages. Initial outcomes indicate these villages hold potential for development into agritourism destinations, emphasizing educational, recreational, and landscape preservation components. This study aims to evaluate the area’s suitability for agritourism, focusing on sustainability through specific zoning. By applying a spatial approach with a scoring and weighting methodology, the study determined that Gading, Lebak, and Tenggilis Rejo are the villages with the highest potential for agritourism. As a result, they have been designated as primary agritourism zones. Conversely, villages with moderate to low potential will serve as supporting and buffer zones.
Greening the Gray: Determining Plant Preferences for Indoor Fitness Gyms in the Philippines
Authors: Fontanoza F S 
Published: August 2024

Abstract
Biophilia is known as the innate connection people have with nature and how green spaces can positively affect basic cognition, mood and health. Mostly applied in urban areas where outdoor green spaces are scarce, designed facilities that incorporate this concept have been observed to be more beneficial to users. Interestingly, one indoor space visited by urban dwellers that have yet to be studied in terms of biophilic design application is fitness gyms. To determine gym members’ preference of planting materials if these were placed in gyms, surveys were distributed online over two weeks. 239 participants composed of actual and potential gym members selected appropriate plants as detailed in the surveys. Site planting considerations or constraints were also identified if these were used indoors. Additionally, their familiarity with biophilia and its advantages were investigated. After the responses were analysed, participants selected Dracaena fragrans, Spathiphyllum wallisii and Epipremnum aureum as top choices of plants for a gym with major considerations on plants’ aesthetic qualities, ecological and psychological benefits, and maintenance. Moreover, more than 50 percent respondents were at least slightly familiar with biophilia. They believed that having plants can improve indoor air quality, make the interiors more aesthetically pleasing and can enhance mood. As per results, it can be said that the respondents supported the idea of designing indoor fitness gyms as biophilic environments although its level of familiarity needs to be increased. This is where professionals come in, by designing facilities such as fitness gyms with plants to optimize biophilia’s benefits.

Authors: Sutrisno A J , Handoko M 
Published: August 2024

Abstract
Rawa Pening Lake is a source of water for irrigation and clean water for the people around the lake. The quality of water is the primary concern for sustainable functioning. This study aims to examine the water quality status of the lake under government regulations. The variables are temperature, total dissolved solid (TDS), total suspended solid (TSS), Escherichia coli (E. coli), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand, phosphate, nitrate, and oil. The study was conducted during the rainy season, from September to November 2020. It’s because of the season that farmers and the community use more of the lake water. The method used is purposive sampling, where a total of 12 locations represent each village, inlet, and outlet. The data analysis used is Storet to determine the water quality class and Inverse Distance Weighted (IDW) for the spatial distribution of water quality classes. The results showed that the water quality class of the lake suffered mild pollution. TSS and DO were variables that influenced that condition. It can be concluded that the lake has sucked sedimentation as a result of the deposits of mud and sand, which can damage the ecosystem of the lake.

Published: August 2024

Abstract
The Thursina Sukamakmur Creative Islamic Boarding School is a boarding school under the State Electricity Company Baitul Mal Foundation (YBM-PLN) ’s management in Sukamakmur Village, Bogor Regency. Education at this Islamic boarding school has the theme of agriculture, where students learn about rice farming and goat and chicken farming. This Islamic boarding school has an area of 16,610 m2 with sloping to steep terrain (more than 25%) and consists of Islamic boarding school buildings, livestock areas, and rain-fed rice fields. The pesantren is surrounded by rain-fed rice fields and is located on a hillside, so it has problems in hydrology when it rains, and strong winds blow from the hill towards the valley. Therefore, a master plan was prepared using an ecological approach, in which the solutions offered minimize artificial landscape elements and optimize the function of vegetation as a wind barrier. The wind barrier is made of pine trees with three layers of thickness. With this ecological approach, it is hoped that the management of the building and environment of the Thursina Creative Islamic Boarding School can be sustainable.

Abstract
As the result from Tangerang Regency’s expansion, South Tangerang stands as one of the youngest cities in Indonesia. The strategic position located near Jakarta makes the suburban city a desirable choice for residence. Therefore, the green city concept exists to standardize sustainable efforts made to balance a city’s environment condition and the population’s life quality. This study aims to evaluate the availability of green open spaces using remote sensing and the implementation of the green city concept in South Tangerang City by utilizing the Asian Green City Index to assess its development and growth in 2010, 2015, and 2020. In 2010, the green open space area reached 3.518 ha (21,34%), then in 2015 ascended to 4.017 ha (24,37%), and eventually able to reach the criteria in 2020 with an area of 7.325 ha (44,43%). Aligning with the green open space’s availability’s escalation trend, the green city concept implementation evaluation also showcases the same growth. In 2010, the implementation performance is considered below average with an AGCI score of 25,61%. Afterwards, in 2015 and 2020, the performance score experiences an incline to the average category with AGCI scores of 44,93% and 59,75% respectively.

Published: August 2024

Abstract
The interaction between humans and their environment forms cultural landscape. One of the cultural landscape in Indonesia is Tana Toraja. The Tana Toraja indigenous people’s way of life refers to the Aluk Todolo religion which regulates the relationships of between human-human, human-God (Puang Matua), and human-environment. The regulation influences their environment, settlement, and agriculture management. Agriculture in Tana Toraja is managed by the community not only for the economic sector but also to ensure food security and preserve traditional cultural activities. This study aims to identify and analyze the elements that make up the agricultural landscape of the Tana Toraja indigenous people, as well as develop a local culture-based agricultural landscape model. The method using in this research was spatial descriptive method by tracing customary manuscripts (literature review), interviewing traditional leaders, and field observations. This research has identified the elements that make up the Tana Toraja agricultural landscape were hills, rivers and springs, forests, rice fields, dryland fields, gardens, fish ponds (gusean), yards, and cattle pens. Integrated agriculture that is carried out based on local customs is paddy-fish integrative farming, rice-livestock integrative farming, agroforestry, and crop-livestock integrative farming. The form of integrated agriculture can be seen at the macro and micro levels and consists of spatial concepts, vegetation concepts, and circulation concepts. At the macro level, which consists of four landform hierarchies in the settlement landscape, which indicates their philosophy of life, they are successively a sacred place (hill), their ancestral home, the general settlement and agricultural areas, and development area for their subsequent offspring.
