Authors: Lin Cong , Chen Yinjie , Feng Siling , Huang Mengxing 
Published: July 2024

AbstractMedical imaging is indispensable for accurate diagnosis and effective treatment, with modalities like MRI and CT providing diverse yet complementary information. Traditional image fusion methods, while essential in consolidating information from multiple modalities, often suffer from poor image quality and loss of crucial details due to inadequate handling of semantic information and limited feature extraction capabilities. This paper introduces a novel medical image fusion technique leveraging unsupervised image segmentation to enhance the semantic understanding of the fusion process. The proposed method, named DUSMIF, employs a multi-branch, multi-scale deep learning architecture that integrates advanced attention mechanisms to refine the feature extraction and fusion processes. An innovative approach that utilizes unsupervised image segmentation to extract semantic information is introduced, which is then integrated into the fusion process. This not only enhances the semantic relevance of the fused images but also improves the overall fusion quality. The paper proposes a sophisticated network structure that extracts and fuses features at multiple scales and across multiple branches. This structure is designed to capture a comprehensive range of image details and contextual information, significantly improving the fusion outcomes. Multiple attention mechanisms are incorporated to selectively emphasize important features and integrate them effectively across different modalities and scales. This approach ensures that the fused images maintain high quality and detail fidelity. A joint loss function combining content loss, structural similarity loss, and semantic loss is formulated. This function not only guides the network in preserving image brightness and texture but also ensures that the fused image closely resembles the source images in both content and structure. The proposed method demonstrates superior performance over existing fusion techniques in objective assessments and subjective evaluations, confirming its effectiveness in enhancing the diagnostic utility of fused medical images.

Abstract
Transformer oil plays a crucial role in insulation and cooling within high-voltage transformers, but it degrades over time. This research proposes a durable sensor capable of detecting the refractive index (RI) of transformer oil when it exceeds the RI of the sensor structure, known as high refractive index (HRI) sensing. The study utilizes a no-core optical fiber (NCF) to monitor the quality of transformer oil. In this setup, single mode fiber (SMF) is employed as both the input and output of the NCF, forming an SMF-NCF-SMF (SNS) sensor. To date, to the use of an NCF in the SMF-NCF-SMF scheme has not been reported for high RI fiber sensing and transformer oil degradation detection. Additionally, this study provides an analysis of the influence of different diameters and lengths of NCF on the sensor’s sensitivity. The HRI sensing performance of the sensor was evaluated both numerically and experimentally by observing power spectrum changes due to leaky modes interference in response to varying transformer oil RI values from 1.4600 RIU to 1.5500 RIU. The NCF, with a geometry of 1 cm in length and 100 μm in diameter, demonstrated remarkable sensitivity, achieving up to 88.285 dBm/RIU for HRI values within the specified range. The sensor effectively discerned various aging levels of transformer oil in power transformer applications. Additionally, since the NCF structure is entirely composed of silica-based materials, it exhibited significant temperature resistance. These characteristics make the SNS structure well-suited for reliable deployment in challenging thermal environments.

Abstract
The electronic properties of h-BC2N/g-C6N6 nanoribbons were calculated using the first principles method. Three states of ferromagnetic, antiferromagnetic, and paramagnetic coupling were set. The energy of the ferromagnetic coupling state was found to be the lowest, indicating that the final stable state was the ferromagnetic coupling state. The thermodynamic stability was also verified in the ferromagnetic coupling state. The h-BC2N/g-C6N6 nanoribbons itself is magnetic with a magnetic moment of 2

and is a direct narrow band gap semiconductor material. In order to change the electronic properties, six different atoms (B, C, N, Al, Si, P) were adsorbed in the h-BC2N/g-C6N6 nanoribbon, and their band structure and charge density were studied. The results show that the adsorption of different atoms in h-BC2N/g-C6N6 nanoribbons will produce different results. Among them, the adsorption of N and P atoms changes its properties from a semiconductor to a half-metal, which can generate a 100% polarized current in the Fermi surface. This provides more development directions for spintronics devices.

Abstract
In the present study we emphasized on the dielectric properties of Ethylene Vinyl Acetate (EVA) filled with untreated and plasma-treated graphene oxide (GO). The chemical fingerprints of EVA/GO were analysed using FTIR. Decreased ID/IG ratio from 2.99 to 2.75 and 1.60 to 1.16 due to exposed plasma was confirmed by Raman spectroscopy. X-ray diffraction (XRD) disclosed the decreased degree of crystallinity. Electric properties were measured by impedance analyser, dielectric constant was increased upto 11% for untreated GO dispersion and 47% for Air treated Plasma GO dispersed EVA composites. Plasma treatment further improved the exfoliated sites of GO and induced the defects, leading to optimized dielectric properties. Improved dielectric properties of EVA/GO can provide valuable insights into the potential applications in the field of electrical connectors, film capacitors, and pseudo capacitors.
Critical speeding-up in dynamical percolation
Authors: Elçi Eren Metin , Garoni Timothy M 
Published: July 2024

Abstract
We study the autocorrelation time of the size of the cluster at the origin in discrete-time dynamical percolation. We focus on binary trees and high-dimensional tori, and show in both cases that this autocorrelation time is linear in the volume in the subcritical regime, but strictly sublinear in the volume at criticality. This establishes rigorously that the cluster size at the origin in these models exhibits critical speeding-up. The proofs involve controlling relevant Fourier coefficients. In the case of binary trees, these Fourier coefficients are studied explicitly, while for high-dimensional tori we employ a randomised algorithm argument introduced by Schramm and Steif in the context of noise sensitivity.

Published: July 2024

Abstract
The abundance of archaeological findings found in damaged and buried conditions in the Trowulan area raises suspicions about the role of geological disasters in the downfall of the Majapahit civilization in the city of Trowulan in the past. This study aims to identify the types and processes of past geological disasters in the Trowulan area based on literature study, stratigraphic data, and granulometry of burial materials at Kumitir Site, Kedaton Site, and Minakjinggo Site. Based on the stratigraphy and granulometry of disaster sediments, there are two types of past geological disasters that struck the Trowulan area, namely earthquake-liquefaction and flash floods. Earthquake-liquefaction disasters are characterized by layers with grain-supported and the presence of collapsed and contorted building structures. On the other hand, flash flood disasters are identified based on layers with matrix-supported compacted material, channeling and fragment imbrication structures, poorly sorting, and subangular-subrounded grain shapes. Based on stratigraphic facies and written records, the disasters that struck Trowulan are identified to have occurred in two periods. The first period includes the Palindu earthquake and Guntur Banyu Pindah flash flood in 1334 AD, while the second period includes the Palindu earthquake in 1450 AD and the Guntur Pawatugunung flash flood in 1481 AD.

Published: July 2024

AbstractMagnetotelluric (MT) method is crucial in geothermal exploration due to its capability to delineate geothermal prospect area by mapping subsurface resistivity distribution. However, in 2D Magnetotelluric modelling, galvanic distortion can distort the regional MT responses, leading to interpretation errors. This study employs phase tensor analysis to eliminate galvanic distortion. Results reveal the dimensionality of each station and three variations of the tipper strike, often referred to as the geoelectric strike. The tipper strike of each station showed varying values, while the tipper strike of all stations indicated N35°E. The tipper strike results required validation against additional geological information, such as faults, fractures, and changes in lithology, significantly influence the conductivity structure of subsurface, which indicated a geological strike of approximately N30°E. This study compares the MT data without rotation, rotation to tipper strike of each station, and tipper strike of all stations to assess effectiveness in eliminating galvanic distortion and improving data quality. The resulting 2D Magnetotelluric cross-section rotated to the tipper strike of all station, exhibits the lowest RMS Error of 2% and roughness of 654.6 among other variations, indicating improve quality. This interpretation identifies a geothermal system in the study area, closely aligning with actual subsurface geological conditions.

Abstract
Pangandaran Regency is one of the best tourist destinations in West Java; many tourist attractions and regional developments to facilitate visiting tourists increase the need for water. However, in some areas of Pangandaran Regency, it is included in the rare groundwater zone according to its aquifer productivity, especially in the fracture rock formation, so it is necessary to conduct research related to the presence of groundwater in the area. This study aims to determine priority areas for the development of groundwater utilization in fractured rock formations located in the Pangandaran Regency. The fracture rock formations in Pangandaran Regency are located from the northwest to the southeast; on the regional geological map, the formation’s name is the Jampang Formation. This study used the Groundwater Potential Index (GPI) method to determine groundwater potential and the Analytic Hierarchy Process (AHP) method to determine water utilization area levels. The parameters used are fracture (F), lithology (L), drainage (D), topography (T), rainfall (R), water usage, land use, and population distribution. This research shows that areas with rare groundwater zones still have groundwater potential that can be developed to meet water needs. There are five priority area classifications: very high is 19 km2, high is 17.92 km2, medium is 67.90 km2, low is 70.99 km2, and very low is 162.40 km2.

Abstract
From 2018 to 2022, there have been 3 floods in Gunungpati District. One factor that influences flood in this area is the infiltration rate. Many factors influence infiltration rates, two of them being land use and slope. This study aimed to determine the distribution of land use and slope gradient in Gunungpati District using GIS-based spatial analysis. The results show that land use in the research area is divided into 5 classes: primary and secondary dry land forests; plantations; shrubs and grasslands; dryland farming; and settlements, paddy fields, bodies of water, and open land. Land use is dominated by settlements, paddy fields, bodies of water, and open land (33.7% of the total area). The slopes in the study area are divided into 5 classes: flat (<8%), gentle (8—15%), wavy (15—25%), steep (25—40%), and very steep (>40%). The wavy class dominates the slopes (29.3% of the total area). Based on these results, a moderate infiltration rate dominates the infiltration rate in the study area.

Published: July 2024

Abstract
Geopark is a concept of sustainable development with three main components: geological diversity, cultural diversity, and biodiversity, with the ultimate goal of protecting the Earth’s diversity, environmental preservation, and broader earth science education. Geological and cultural diversity in a geopark concept does not stand alone, but there is a relationship. Ternate Island is a volcanic island with Gamalama Mts as a Quaternary Volcano. The area around the volcano is comfortable because there is sufficient water despite the eruption disaster. Megalithic artefacts such as menhirs and pseudo dolmens are cultural products closely tied to the significant stone tradition. Megalithic remains on Ternate Island are represented by the presence of Jere, a local term to refer to the sacred places usually represented by menhirs and whole boulders in 56 locations. The regent government plans to develop it as an island geopark. Before being proposed, a study of geological, biological, and cultural diversity must be carried out to propose establishing a geoheritage and preparing a Geopark proposal document. This initial research uses the overlay method to identify geological conditions, determine the distribution of megalithic artefacts, and analyze their relationships.

Abstract
The characteristics of the geological structures controlling the presence of Sukadana basalt on the Earth’s surface are still an enigma. Therefore, this study was conducted to determine the probable types of geological structures and their orientations that could control the occurrence of Sukadana Basalt lava on the Earth’s surface. To seek answers to this problem, this study utilized vesicular structure data from Sukadana Basalt based on 13 rock samples from 13 observation points. We measured the diameter of the vesicular and the sum of the megascopic vesicular per cm2 for every sample. We used a scale of 1-5, where 1-2 indicated as small-low intensity vesicular, 3 indicated as medium-middle intensity vesicular, and 4-5 indicated as large-high intensity vesicular. it was found that there are three groups of vesicular that were developed in Sukadana Basalts: small-low, medium-middle, and large-high groups. This study gives information that there are three fracturures including two normal faults at the northern and southern parts of Sukadana Basalt and one fisurre in the middle of Sukadana basalt. The normal fault at the southern part of Sukadana Basalt has the widest fault core spacing and the fissure at the middle of Sukadana Basalt has the narrowest fissure core spacing. All groups show northwest-southeast striking fractures. This study will provide a new point of view that in interpreting subsurface geological structures can use primary structure characteristics data, especially vesicular structures.

Authors: Abhista A , Setianto A 
Published: July 2024

Abstract
Remote sensing nowadays is used to quickly and effectively obtain information about an object, area or phenomenon and can be applied to large areas that are sometimes difficult to reach. Satellites with multispectral imagery are commonly used in geological mapping, but have drawbacks when used in tropical areas such as Indonesia, with dense vegetation, fast sedimentation rates and highly weathered that will cover fresh rocks making it difficult to interpret geological condition through aerial photo. Light Detection And Ranging (LiDAR) images using laser beams to produce elevation data (x,y,z) with high spatial resolution and can penetrate the surface of vegetation are expected to be a solution in areas with dense vegetation that are sometimes difficult to reach. The study was conducted by interpreting the morphometric aspects using Digital Terrain Model (DTM) data processed from LiDAR imagery with a spatial resolution of 1 m/pixel to display the topographical surface in detail. The morphometric aspects used include slope, surface roughness, aspect, hillshade, and stream pattern. Field data validation through surface mapping is carried out to correct the lithology interpretation by comparing the results of LiDAR image interpretation. Field data validation results show that interpretation using LiDAR imagery has good results (79%) through overall accuracy percentage, with the lithology units being sandstones, siltstone, breccias, and andesitic igneous rocks. The lineament interpretation of the DTM data indicates the existence of a geological structure in the form of a normal and strike-slip fault in the study area.

Published: July 2024

Abstract
The gravity method is commonly used in geophysics for fault mapping. This method provides an overview of the subsurface density distribution. When applied to fault areas, the density gradient contrast can be used to map the fault geometry structure. The research area for this study is Penang Island, Malaysia, which is predominantly composed of granite. The Penang Island granite formation was created during the Triassic period, approximately 209 to 22 million years ago (Kwan and Yap, 1986). It underwent uplift during the Oligocene-Miocene period, exposing the previously buried granite. The second formation is a quaternary sediment that is believed to have formed during the Pleistocene and Holocene (Kamaluddin, 1990). Penang Island has 14 faults scattered throughout, with 5 main faults in the middle (Ong, 1993). The study aimed to determine the fracture geometry using the gravity method. The analysis revealed two main rock types: granite with a density range of 2-2.8 gr/cm3 and quaternary sediment with a density of 1.85-2 gr/cm3. Fault geometry analysis was conducted using the SVD method on four passages in Penang Island to identify fault types. The results showed six normal faults and seven thrust faults. Faults No. 3, 4, 8, 9, 12, and 13 are predicted to be normal faults, while Faults No. 1, 2, 5, 7, 10, 11, and 14 are predicted to be thrust faults. The dominant direction of the fault is North-South. The fault geometry on North Pluton has an average depth of 250 m with an average dip angle of 68°, while the fault on South Pluton has a depth of over 400 m with an average dip angle of 65°.

Abstract
The Barito Basin is one of the basins in South Kalimantan and serves as a coal-producing region. One of the coal-bearing formations present in the Barito Basin is the Miocene Warukin Formation. The purpose of this research is to understand the characteristics of coal macerals, including the dominance of macerals and their microfacies, as well as the type and development of the mire where coal is deposited. This information is crucial for the coal geological study in the Kandangan region, South Kalimantan. The methods employed include organic petrography analysis, proximate and ultimate analysis on seams L8, L5, L5B, M16, and MS02 collected using the ply-by-ply method.The results of the subbituminous coal petrography examination in this formation show the dominance of vitrinite ranging between 41.34-74.04% vol, liptinite between 11.61-38.24% vol, inertinite between 2.21-32.32% vol, and mineral matter ranging from 0.17-1.98% vol, predominantly composed of pyrite. The ash content data ranges from 1.36-15.45 (% wt, adb). The sulfur content data ranges from 0.1-0.45 (% wt, daf). Based on the distribution of maceral abundance, coal microfacies can be categorized into five groups: (1) gelovitrinite-rich group, (2) telovitrinite-rich group, (3) liptinite-telovitrinite-rich group, (4) inertinite-rich group, and (5) telovitrinite-inertinite-rich group. The lower section is predominantly characterized by the telovitrinite-inertinite-rich group. In the middle section, the inertinite-rich group takes precedence, alternating with the liptinite-telovitrinite-rich group. The upper segment is primarily marked by the gelovitrinite-rich and telovitrinite-rich groups. The developed paleomire includes repetitions of topogenous mire and ombrogenous mire. The paleomire type is a wet forest swamp under limnic and telmatic conditions. The dominant original vegetation consists of woody plants, although shrubby plants are also found in significant amounts. Moderate to high gelification levels indicate that the peat was constantly inundated with water.
