Authors: Peng Yuankang , Cui Yian , Guo Youjun , Li Hao , Liu Jianxin 
Published: December 2024

Abstract
The self-potential method is an effective geophysical method for monitoring groundwater and soil pollution. However, due to the flow of groundwater, the observed mixed signals of pollution sources are often constantly changing. How to accurately describe the distribution changes of pollutants is an important issue. We propose an inversion algorithm based on particle filter, which can invert and monitor the movement of underground pollution sources. The pollution source is regarded as a polarized sphere, and then we set up a dynamic numerical model. Then we successfully achieved dynamic monitoring of the burial depth of the model, verifying the effectiveness and accuracy of the algorithm.

Published: December 2024

Abstract
This study investigates the thermal runaway characteristics of lithium-ion batteries and sodium-ion batteries under external heating conditions. By collecting temperature, strain, and voltage data, the thermal runaway behavior of two-type batteries is compared. Results show that lithium-ion batteries experience rapid temperature rise and early onset of internal damage, evidenced by sharp voltage drop and increased temperature rise rate. In contrast, sodium-ion batteries demonstrate slower TR onset but exhibit more severe thermal runaway effects, including higher peak temperatures and significant physical damage due to combustion. The comparative analysis indicates that lithium-ion batteries trigger TR earlier but with less severe damage, while sodium-ion batteries, despite their later onset, undergo more intense thermal runaway events. These findings highlight the importance of strengthening safety protocols and materials to address thermal runaway behavior under different battery thermal abuse.

Authors: Li Hua , Wu Zhengrong , Yang Xianzhi , Yang Chen 
Published: December 2024

Abstract
Affected by the resource allocation skew problem, which leads to the low utilization rate of resources, we propose to study the optimization method of dynamic resource allocation of compiler subsystem under the environment of electric power IoT (Internet of Things). The skewness willingness function is constructed to reflect the imbalance degree of the compiler subsystem partitioning in the power IoT environment, and at the same time, quantitative indexes are provided for evaluating the effectiveness of the compiler subsystem partitioning algorithm in the power IoT environment. In the resource allocation stage, combined with the compiler subsystem resource tilt allowable threshold, the dynamic allocation of resources is carried out based on the existing compiler tasks in accordance with the priority, with the goal of minimizing the additional waiting time (tilt). In the test results, the compiler subsystem is tested for the distribution of ηEE
under different types of requests is always within 0.25 J/bit. Compared with the control group, it has obvious advantages in processing performance and stability.
Research on obstacle recognition method of transmission line in alpine region based on depth camera
Authors: Ren Boyu 
Published: December 2024

Abstract
Ice and snow on transmission lines in alpine areas lead to increased tower load and short circuits of transmission lines. Tower collapses and power outages caused by ice have a serious impact on factory production and people’s lives. With the development of robot technology, deicing robots have become an important research direction to solve the icing problem of transmission lines. The deicing robot mainly completes actions such as walking, obstacle crossing, and deicing on the transmission line. In the process of robot walking, accurate identification of obstacles on the transmission line is the basic condition for the deicing robot to complete the deicing work, which provides a basic guarantee for the deicing robot to cross the obstacles. Therefore, in this paper, a visual recognition method based on a depth camera is proposed by combining the obstacle characteristics on the 220 KV high-voltage transmission line.

Published: December 2024

Abstract
As global productivity levels continue to escalate, issues such as energy shortages and environmental pollution have become increasingly pressing. Wind energy, owing to its vast reserves and zero-emission characteristics, has garnered significant attention for development and utilization. Nevertheless, the inherent randomness and uncertainty of wind power have adverse effects on the frequency security of power systems. Consequently, this paper proposes an optimization approach for unit commitments that integrates frequency security constraints with wind-storage frequency regulation control. In the proposed solution, based on a multi-machine model where both wind power and energy storage contribute to frequency control simultaneously, an expression for system frequency variation considering wind-storage frequency regulation is derived. Starting from the frequency response models of various power sources, an equivalent method is adopted to obtain the minimum point frequency constraint, leading to the development of a unit commitment model that incorporates both wind-storage frequency regulation and frequency constraints. The effectiveness of the proposed method is then validated through comprehensive simulation experiments.

Abstract
The adoption of mechanized and intelligent harvesting equipment is an effective approach to enhancing the stability and competitiveness of the pomelo industry. This study presents the development of a harvesting device tailored for pomelos by improving target recognition algorithms and optimizing the picking mechanism. A fruit stem posture fitting algorithm based on the morphological characteristics of pomelos was developed, capable of obtaining spatial information on fruit stems even in obstructed environments. A serial PPRP picking mechanism with a fault-tolerant end-effector was designed, and kinematic equations and control theory models were established. Experimental results demonstrate that the workspace of the designed robotic arm for pomelo harvesting has a height of 1.9 meters and a depth of 1.3 meters, with a recognition accuracy of 94% and a picking success rate of 72%. The harvesting efficiency reached two fruits per minute, making the device suitable for operations in both structured and unstructured orchard environments.

Published: December 2024

Abstract
COSINE-100 is a direct dark matter search experiment, with
the primary goal of testing the annual modulation signal observed by
DAMA/LIBRA, using the same target material, NaI(Tl). In previous
analyses, we achieved the same 1 keV energy threshold used in the
DAMA/LIBRA's analysis that reported an annual modulation signal with
11.6σ significance. In this article, we report an improved
analysis that lowered the threshold to 0.7 keV, thanks to the
application of Multi-Layer Perception network and a new likelihood
parameter with waveforms in the frequency domain. The lower
threshold would enable a better comparison of COSINE-100 with new
DAMA results with a 0.75 keV threshold and account for differences
in quenching factors. Furthermore the lower threshold can enhance
COSINE-100's sensitivity to sub-GeV dark matter searches.
Biodegradable silk fibroin membranes for potential localized treatment of melanoma: optimized preparation and in vitro study
Authors: Zhang Mingshuang , Han Shisong , Wang Ya 
Published: December 2024

Abstract
As a lethal skin cancer, melanoma is highly aggressive and metastatic with high recurrence rates and the common therapy is surgical resection followed by chemotherapy. To minimize the side effects of chemotherapeutic drugs and prevent tumor recurrence in situ, localized therapy is a more suitable treatment method. Here, a fully biodegradable silk fibroin (SF) membrane loaded with the therapeutic drug doxorubicin (Dox) is fabricated for potential localized chemotherapy of melanoma. SF has a high loading capacity of Dox with a maximum mass ratio of Dox/SF equal to 2.5% without generating precipitates. Water annealing (WA) is utilized to enhance the membrane’s stability in the aqueous environment by inducing the formation of β-sheets and the treated membrane was stable in water for at least 15 d. Meanwhile, both the ultimate tensile strength and Young’s modulus of the SF membrane were significantly enhanced after the WA. When incubated with Proteinase K, the mass loss of water-treated membranes followed a linear trend and the degradation coefficient was −30.39, −25.31, and −18.62 for 1 ml, 2 ml, and 3 ml membranes respectively. All the water-treated membranes could be fully degraded within 5 h. By adjusting the membrane thickness and Dox amount, precisely controlled sustained release of Dox is achieved with an initial release rate of 10.39–80.65 μg h−1. The fabricated SF-Dox membrane demonstrates excellent therapeutic effects on melanoma cells with the lowest viability of 51.59% after 24 h and 9.48% after 48 h while being highly biocompatible with normal cells. These findings highlight the potential of SF-Dox membranes as an effective localized therapeutic strategy for melanoma, warranting further investigation in preclinical and clinical settings. This work provides a novel paradigm not only for the development of localized therapy of melanoma but also for the postoperative care systems after melanoma surgical excision.

Published: December 2024

Abstract
The effects of cropland management on yield and greenhouse gas (GHG) emissions vary among crops, and comprehensive and quantitative analyses of relevant factors are needed to make informed management decisions. The study assessed the response of global crop yields and GHG to cropland management and natural factors (including mean annual temperature, mean annual rainfall, soil pH, soil C N ratio (SCN), soil organic matter, crop type, biochar (application rate Brate, biochar feedstock, C N ratio BCN, biochar pH BPH, biochar organic matter BTC), irrigation, N fertilizer (Nrate), tillage, straw management, plastic film mulch, duration of experiment, economic development, geographic location (state, country)) involving 167 papers from 17 crops in 27 countries, with a total of 1249 pairs of observations by using meta-analysis. The results showed that biochar application throughout the year improved crop yields, reduced GHG and was more suitable for use on C4 crops. The contribution of straw return to CH4 and CO2 was 78.3% and 35.6%, respectively. The effect of intermittent irrigation (I-IRR) on the yield of C4 crop was 25.7% higher than that of C3 crop. The optimal nitrogen utilization rates for wheat and corn were 253.20 kg·N·hm−2 and 239.84 kg·N·hm−2, respectively, and N fertilizer was more effective in reducing GHG of C3 crops. Among the 20 influencing factors, the relative impact of annual rainfall was the most significant, accounting for 69.3% of N2O and 40.39% of CO2 emissions, respectively. SCN had the most obvious impact on CH4、GWP and Greenhouse Gas intensity (GHGI), reaching up to 51.45%、35.98% and 43.46%, This study quantitatively assessed the response of different types of crop yields and GHG emissions to cropland management practices and natural factors, and provided a basis for making management decisions to enhance global crop yields and reduce GHG.
The strategic and governance implications of solar radiation modification: perspectives from delegates of international climate negotiations
Authors: Cherry Todd L , Kallbekken Steffen , McEvoy David M , Siu Wai Yan 
Published: December 2024

Abstract
The lack of progress in addressing climate change has led to increased interest in solar radiation modification (SRM)—a collection of large-scale interventions that cool the planet by managing the amount of solar radiation that reaches the earth. SRM complicates climate change governance because, in addition to advancing collective action to reduce greenhouse gas emissions, governance needs to restrain unilateral SRM action while balancing diverging actor interests, ethical risks and scientific uncertainty. We survey international climate policy experts for their assessments of the potential for effective global governance of SRM and the likelihood of possible international responses to unilateral SRM scenarios. Experts are pessimistic about the global community achieving effective SRM governance, and they believe unilateral SRM action will trigger international responses and conflicts. Experts believe softer responses are most likely (e.g. diplomatic sanctions) but the potential for stronger responses, including military action, are non-trivial. Relative to the Global North, experts from the Global South are relatively more supportive of SRM, including the development of SRM, the inclusion of SRM in international negotiations, and the deployment of SRM in a climate emergency.
Wigner current in multidimensional quantum billiards
Authors: Seidov S S , Bezymiannykh D G 
Published: December 2024

Abstract
In the present paper we derive the Wigner current of the particle in a multidimensional billiard—the compact region of space in which the particle moves freely. The calculation is based on proposed by us previously method of imposing boundary conditions by convolution of the free particle Wigner function with some time independent function, defined by the shape of the billiard. This method allowed to greatly simplify the general expression for the Wigner current, representing its
p
–component as a surface integral of the product of the shifted particles wave functions. The results are also connected to an alternative approach, which takes into account the boundary conditions by adding the

Authors: Lamuse Maulina , Putra Heriansyah , Erizal  , Ihsani Zalfa Maulida 
Published: December 2024

Abstract
Clay shale, known for its expansive and weathered characteristics, poses challenges in construction when exposed. The calcite precipitation method offers a viable solution to bolster load-bearing capacity and counteract potential soil expansion while ensuring reversible changes. This study aims to evaluate improvements in the shear strength parameters of clay shale through the calcite precipitation method. The research involved soil properties tests, hydrolysis rate and precipitation ratio analyses, and direct shear tests on both saturated and dry soil specimens. Results showed clay shale samples with PL, LL, and PI values of 41.60%, 21.97%, and 19.62%, respectively, categorizing them as low to medium plasticity clayey soils (CL). The optimal treatment concentration was determined at 20 g/L soybean concentration with a precipitation ratio of 93%. In treated-saturated conditions, cohesion (c′) increased from 4.10 kPa to 12.07 kPa, and the internal friction angle (φ′) rose from 0.54° to 2.87°. Remarkable enhancements were observed in treated-dry samples, with c′ increasing from 7.53 kPa to 183.84 kPa, and φ′ rising from 2.31° to 19.25°. The SCU-CP method effectively improved the properties of dry clay shale.
Numerical Modelling of Seepage Potential on the Dadahup-G1/A5-B4 Road, Central Kalimantan, Indonesia
Authors: Anggiawan Rizal , Karlina  , Rahardjo A. P. , Nirwan E. 
Published: December 2024

Abstract
The Dadahup-G1/A5-B4 road is part of a central government project in Central Kalimantan to support food estate activities in the Dadahup Swamp Irrigation Area. The road is built on the embankment of the primary and secondary irrigation canals. The road is built on top of soil fill from sedimentation in the canal. The soil is dominated by silty clay. Silty clay is characterized by low density, high water content, and limited drainage ability. The soil easily compresses or loses volume when subjected to loads. Varying water levels in the channel can cause seepage from the primary channel across the roadway to the channel on the other side. High water content can also cause stability and infiltration problems that need to be maintained. The purpose of this study was to determine the seepage potential and its effect on the stability of the roadbed. The subject of the study was water level fluctuations. The variables considered include channel water level, groundwater level, and soil permeability. The method used the numerical analysis model of the GeoStudio program with SEEP/W to analyze seepage on the embankment road. The research findings indicate that the higher the water level, the greater the seepage discharge of the water level at the upstream face and the lower the seepage discharge of the water level at the downstream face. Based on the criteria for accepting seepage in the embankment body, the current condition of the embankment is still in a safe condition. The safety factor at the maximum, mean, and minimum water level conditions meet the requirements (SF>4). The research results also show that the higher the water level, the lower the safety factor. However, to confirm the results obtained, further analysis is needed regarding the study of the potential risk of landslides impacting road embankments.

Abstract
The design plans for the 433-meter-long Diversion Tunnel in the BBWS Cidanau Ciujung Cidurian area, situated on the right side of the Pasir Kopo Dam in Lebak, Banten, involve the application of the Rock Mass rating (RMR) method for rock mass classification. This approach is also utilized to determine the excavation method for the tunnel, stand-up time, and support systems. In addition, the tunnel support system uses the Q Systems method to address potential geological uncertainties. Surface and subsurface geological mapping, drill core evaluation, and laboratory tests were conducted to collect essential data. Specifically, surface geological mapping and drill core assessment were conducted to evaluate the rock mass quality along the tunnel’s path. Laboratory testing provided details on the physical and mechanical characteristics of the entire rock mass based on drill core samples. The tunnel section consists of a Tuff rock unit and a Lapilli Tuff rock unit, both categorized as having poor (39,83) to fair (42,8 – 48,71) rock mass quality. The drilling and blasting method is recommended, and Excavation techniques differ based on rock mass classification, with the top heading and bench method varying from 1.00m to 1.50m for poor rock (1 zone) and from 1.50m to 3.00m for fair rock (6 zone). The support system for poor rock mass classification includes No steel set required; Rock bolts 3 m and shotcrete 50 mm, and No steel set required, and for fair rock mass, Rock bolts 4 m and shotcrete 50-100 mm in the crown, 30 mm insides. For zones 1,2,5,7 with very poor quality based on Q–Systems support systems using Shotcrete Rock Fibers, Sprayed concrete E = 500 with a 6 cm - 9 cm thickness and bolting length 2.70 m with space 1.5 m – 1.7 m and For zone 3,4,6 using Shotcrete Rock Fibers, Sprayed concrete E = 500 with a 9 cm - 12 cm thickness and bolting length 2.70 m with space 1.3 m – 1.5 m.
