The Beekeeper Formation, a mixed carbonate-siliciclastic reservoir, has long been known as a proven gas reservoir in the northern Perth Basin, Australia. However, its characteristics, and spatio-temporal distribution are still not well understood. There are two main objectives of this study: (1) to identify the main cutting facies groups/subgroups, and electrofacies of the Beekeeper Formation;and (2) to understand spatio-temporal characteristics, and development of the Beekeeper Formation. Integrated multi analyses have been conducted to achieve these objectives including cutting, wireline logging, and XRF analyses. Fifteen types of cutting components, and nine electrofacies were identified forming the Beekeeper Formation. The Beekeeper Formation consists of nine facies sub-groups, and these are classified into carbonate-dominated facies group, siliciclastic-dominated facies group, and mixed carbonate-siliciclastic facies group. Furthermore, this formation can vertically be divided into three parts on the basis of the main facies groups: the lower, middle, and upper parts. The lower and upper parts consist predominantly of siliciclastic materials, while the middle part is dominated by carbonate materials. In the north of the study area, the Beekeeper Formation consists predominantly of siliciclastic materials with minor carbonate materials, whereas in the central to south it consists mainly of carbonate material with minor-moderate siliciclastic materials. Various processes have influenced the evolution of the Beekeeper Formation including influx of siliciclastic components, mixing of carbonate and siliciclastic materials, suitable environment for the growth of carbonate biotas, sea level fluctuation, and tectonic activities. It is expected that findings from this study will provide new insights into characteristics of mixed carbonate-siliciclastic reservoirs in general, and will have regional and global applicability. © 2025 The Authors

This research introduces a deep learning framework that combines convolutional neural networks with autoencoders to improve the diagnostic accuracy of knee osteoarthritis. The study utilized a publicly available dataset from the Mendeley Data repository, where knee joint images were preprocessed using Contrast Limited Adaptive Histogram Equalization to enhance contrast and ensure consistent image sizing. Initially, an autoencoder was employed in an unsupervised manner to learn compressed representations of the data. These representations were then used to train a CNN to classify knee images into 'healthy' and 'osteoarthritic' categories. The model was trained using an 80:20 split for training and testing data, incorporating early stopping and data augmentation techniques to prevent overfitting and enhance generalization. Performance metrics such as accuracy, precision, recall, and the area under the Receiver Operating Characteristic curve (ROCAUC) were used to evaluate the model, resulting in a high test accuracy of 98.95%. The high precision and recall rates further confirmed the model's robustness in diagnosing KOA. To enhance interpretability, Gradient-weighted Class Activation Mapping (Grad-CAM) was applied to identify critical regions in the images that influenced the model's decisions. Additionally, t-Distributed Stochastic Neighbor Embedding (t-SNE) was used to visualize the high-dimensional encoded features in a two-dimensional space, providing deeper insights into how the model differentiates between classes. The promising results of this deep learning approach suggest its potential for broader applications in medical imaging diagnostics. By providing healthcare professionals with a tool that enhances diagnostic accuracy and operational efficiency, this framework lays the foundation for developing scalable, AI-driven diagnostic systems for various complex medical conditions. © 2025 Institute of Physics Publishing.

The adsorption and dissociation of hydrogen molecules are essential for various hydrogenation reactions and utilization in hydrogen storage. Herein, by utilizing Density Functional Theory (DFT), we introduce Zn atoms to a Pd subnanometer cluster to investigate H2 dissociation. Two cluster models with ZrO2 support are considered, namely Pd4Zn/ZrO2 and Pd3Zn2/ZrO2. We find that H2 molecule strongly adsorbed on the Pd clusters, where Pd3Zn/ZrO2 gives slightly lower adsorption energy. Both configurations were found to facilitate the H2 dissociation into two H atoms thermodynamically, which takes place on top of Pd atoms with activation barriers of 0.63 and 0.67 eV on the Pd4Zn/ZrO2 and Pd3Zn2/ZrO2., respectively. Overall, this study provides new insights into the effect of cluster forms of Pd-based catalyst on the reaction mechanism of H2 dissociation. © 2025 Institute of Physics Publishing.

This study proposes a new approach, a communal-based domestic rainwater harvesting (CDRWH) system, which is a new model that combines domestic and communal rainwater harvesting systems. This model is an alternative solution to improve system performance and utilize rainwater overflow from the system. Rainwater runoff from several domestic tanks is channeled to a communal tank to be collected, processed, and redistributed to needy domestic tanks. Overflow from the communal tank is used for groundwater recharge. The CDRWH system model aims to increase water supply, reduce runoff, and conserve groundwater. The model simulation uses daily water balance analysis and yield before spillage algorithm. The simulation scenario uses variations in roof area, number of house occupants, storage tank volume, and rainfall categories: 20 years, wet year, normal year, and dry year. Jagakarsa, an urban area in South Jakarta, was selected for the CDRWH system modeling. The results showed that the CDRWH model significantly improved the performance of the volumetric reliability (VR) and time reliability (TR) systems. In addition, the model could show a comparison of total groundwater recharge (GWR) and groundwater extraction (GWE), where the GWR capacity was higher. This allows centralized rainwater management in communal tanks, thereby reducing groundwater usage. The design of this model is simple. Therefore it can be easily duplicated for application in other locations. © 2025 The Authors

Light is a fundamental element in worship space design, shaping sacredness through visual perceptions of clarity, comfort, and experience. St. Peter's Cathedral in Bandung was studied in physical spaces and virtual reality (VR) under three light scenarios: daytime with natural light, afternoon with combined light, and night-time using artificial light. Data were collected via high dynamic range (HDR) imaging analysed with Aftab Alpha software, questionnaires, and physiological measurements. Eighteen participants experienced the cathedral physically, while 20 observed 360° images in VR. Heart rate and brain waves were recorded during the VR sessions. Both groups reported similar emotional and monumental experiences, confirming VR's potential to replicate sacred atmospheres. However, dynamic daylight in real space, HDR image used, and display technology in VR may cause perceptual differences in visual clarity and comfort across settings. The sacred experience is shaped by two emotional dimensions: upliftment and suffering. Colourful light and a non-uniform distribution, particularly from stained glass, are effective in creating emotional uplift by evoking wonder and deep emotional engagement. Warm and dim lights can contribute to both emotions by inducing contemplation and a sense of vulnerability. Balanced lighting that considers both clarity and comfort is essential for achieving a full emotional spectrum. Physiological responses, such as elevated heart rates and specific brain wave patterns offer valuable insights into spiritual effects of light, supporting deeper exploration of sacred experiences through measureable data. © 2025

Autonomous driving technology relies heavily on sensor data for environment perception. Heterogeneous sensors such as lidar, radar, and camera have their own strengths and limitations. Therefore, relying on any single sensor would restrict the effectiveness of autonomous driving technology. However, integrating data from such heterogeneous sensors poses challenges due to differences in their representations. This article outlines a deep learning network aimed at designing modality-agnostic multi-modal fusion architecture. We study sensor data from different modalities and learn fine-grained representations using modality-specific feature encoders independently. Then, a multimodal attention-based network (MMA-Net) is proposed to fuse the data from heterogeneous modalities. The proposed MMA-Net fuses multi-modal sensor data by jointly exploiting the inter-modality and intra-modality relationships among camera, lidar, and radar sensors. The effectiveness of the proposed multi-modal fusion architecture is demonstrated using 2-D object detection metrics through extensive experiments on a dataset generated using the CARLA simulator.

@***: an ongoing archive of seeing

Photographies 2021年第2期14卷 199-220页

作者： Reis, Cláudio Doctoral Program in Digital Media Faculty of Engineering University of Porto Portugal

Since 2014, photographer Stephen Shore has been exploring Instagram as a new body of work, having its own online portfolio entry next to iconic series as American Surfaces and Uncommon Places. Instead of joining contemporary debates concerning the crisis of representation implicit in the networked condition of the photographic image, Shore is keen to engage with Instagram through the lens of modernism, concentrating his attention on the visual characteristics intrinsic to photography as a medium, a reasoning previously encapsulated in the primer The Nature of Photographs. Building upon selected samples from Shore’s pre-digital archive in addition to his most recent series, Details, the research takes @*** as a significant case study to examine how Instagram affects the modernist emphasis on seeing photographically the ordinary, evaluating the contemporary relevance of Shore’s networked notational impulse when many Instagram users engage with photography to keep a quasi-diaristic practice. Looking at the traces of everyday life, envisaged for Instagram or the gallery wall, the camera is but a tool for reflecting upon a concept Shore long borrowed from the great writer T. S. Eliot: the “objective correlative”, allowing for poetry to be found, and given visual structure. © 2021 Informa UK Limited, trading as Taylor & Francis Group.

JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE 1971年第3期22卷 193-+页

作者： BELZER, J ISAAC, A FINKELSTEIN, E WILLIAMS, J Department of Industrial Engineering Interdisciplinary Doctoral Program in information Science. University of Pittsburgh United State of America

The Curriculum Committee of the Special Interest Group/Education Information Science of ASIS is charged with the responsibility for determining the scope and characteristics of information science pro- grams in the U.S. & Canada in terms of curriculum developments and course offerings. To fulfil' this responsibility, questionnaires were developed to elicit reliable information concerning courses being offered relating to information storage and retrieval, information science and/or documentation. The data requested included course levels, pre- and post-requisite courses, textbooks used, topics covered, frequency with which offered, etc. Responses were received from 45 schools, providing information about 1 85 courses and 242 topics. Using several methods of clustering the data, it was difficult to arrive at firm results, because of the diversity and scatter of the topics included in this field. It was therefore decided to hold a workshop of experts which would examine the validity of the questionnaire results. This workshop, using the Delphi technique to arrive at consensus, was held at the University of Pittsburgh on September 21-23, 1970. Sixteen specialists in the field representing universities, industry and government were brought together to participate. Consensus was reached in identifying nine factors which contribute to the curriculum in information science and seven courses which constitute the core for the Master's program. The topics to be included in each of these courses were also isolated. The 9 factors are: Psychology/Behavioral Science, Language/Linguistics, Management, Statistics, Library Science, Systems, Mathematics, Information and Communication Theory, and Computer Science/Automata. The 7 courses are: Introduction to Information Science, Systems Theory and Applications, Mathematical Methods in Information Science, Computer Organization and programming Systems, Abstracting/Indexing! Cataloging, Information and Communication Theory, and Research
