Physics-aware cross-domain fusion aids learning-driven computer-generated holography

The rapid advancement of computer-generated holography has bridged deep learning with traditional optical principles in recent years. However, a critical challenge in this evolution is the efficient and accurate conversion from the amplitude to phase domain for high-quality phase-only hologram (POH) generation. Existing computational models often struggle to address the inherent complexities of optical phenomena, compromising the conversion process. In this study, we present the cross-domain fusion network (CDFN), an architecture designed to tackle the complexities involved in POH generation. The CDFN employs a multi-stage (MS) mechanism to progressively learn the translation from amplitude to phase domain, complemented by the deep supervision (DS) strategy of middle features to enhance task-relevant feature learning from the initial stages. Additionally, we propose an infinite phase mapper (IPM), a phase-mapping function that circumvents the limitations of conventional activation functions and encapsulates the physical essence of holography. Through simulations, our proposed method successfully reconstructs high-quality 2K color images from the DIV2K dataset, achieving an average PSNR of 31.68 dB and SSIM of 0.944. Furthermore, we realize high-quality color image reconstruction in optical experiments. The experimental results highlight the computational intelligence and optical fidelity achieved by our proposed physics-aware cross-domain fusion.

Green technology innovation or pollution substitution? an evolutionary game for high-Energy-consuming enterprises’ strategy from a consideration of energy-consuming trading rights

ABSTRACT The energy-consuming rights trading (ECRT) environmental regulatory policy starting from demand side reform has a significant influence on the enterprises’ production strategies. However, there is still a lack of research on dynamic mechanisms from a micro perspective. Referencing ECRT policy implementation, this paper incorporates government, the public, and high-energy-consuming enterprises into a unified framework, and constructs a tripartite evolutionary game model to explore the enterprises’ production strategy under the reward and punishment accountability mechanism. Then, a case study is addressed to examine the role of government. The results show that: (1) The steady-state conditions of the three parties depend on their own cost–benefit circumstances. Enterprises’ production strategy is driven by the coordination of the government and the public. (2) Achieving ideal equilibrium path evolution requires that the expected benefits of green technology innovation more strongly than the expected benefits of ‘pollution substitution’ practices. (3) A strict accountability system that includes penalties and rewards can enhance public supervision and accelerate the transformation of government active regulatory supervision strategies, stimulating the internal driving forces that motivate enterprises’ green technology innovation. The findings provide references for promoting the implementation of ECRT and helping to achieve the strategy of ecological civilisation construction.

Analysis of implementation science strategies to train laparoscopic surgical skills among Liberian surgeons using ALL-SAFE.

Significant disparities exist in laparoscopic training opportunities for surgeons in low- and middle-income countries (LMICs). ALL-SAFE is an innovative, low-cost training system for LMIC surgeons' laparoscopic development. However, strategies to implement and scale ALL-SAFE are unstudied. We aimed to assess the impact of implementation science strategies on ALL-SAFE uptake in Liberia, a novel and low-resource context. This study used implementation science approaches to evaluate ALL-SAFE uptake in three Liberian hospitals: John F. Kennedy Medical Center, Phebe, and ELWA. Five validated implementation strategies of program orientation, local champions, network weaving, feedback mechanisms, and practical supervision were piloted. All five strategies were implemented at two hospitals, while four strategies, excluding clinician supervision, were implemented at the final site as a pseudo-control, to evaluate the impact of resource-intensive supervision. Participants included surgical consultants, residents, and medical students. Engagement was assessed with mixed methods including participant number, practice hours, module completion rates, and strategy feasibility through end-user interviews. Across three hospitals, 33 participants used ALL-SAFE for 87.8 total training hours (5,268min). Participant numbers varied across sites (NJFK = 20, 80%; NPhebe = 7, 88%; NELWA = 6, 86%), as did practice times (TotalJFK = 3,060min, Median time/ParticipantJFK = 103min; TotalPhebe = 1,434min, Median time/ParticipantPhebe = 126min; TotalELWA = 774min, Median time/ParticipantELWA = 100min). Sites with practical supervision demonstrated higher engagement than those without (P = 0.042). Interviews (n = 8) revealed positive perceptions toward program orientation, practical supervision, and network weaving. Participants recommended thirteen additional strategies for sustainability including translating ALL-SAFE skills to patient care. Our study is one of the first to evaluate implementation science strategies for laparoscopic training in sub-Saharan Africa. The implementation bundles of five validated strategies were considered feasible by Liberian surgeons in both urban and rural hospitals. Mixed methods suggested a positive association between engagement and the resource-intensive practical supervision strategy. Future studies should focus on quantifying individual strategy contributions with rigorous implementation designs and assessing sustainability strategies.

Cloud Detection Using a UNet3+ Model with a Hybrid Swin Transformer and EfficientNet (UNet3+STE) for Very-High-Resolution Satellite Imagery

It is necessary to extract and recognize the cloud regions presented in imagery to generate satellite imagery as analysis-ready data (ARD). In this manuscript, we proposed a new deep learning model to detect cloud areas in very-high-resolution (VHR) satellite imagery by fusing two deep learning architectures. The proposed UNet3+ model with a hybrid Swin Transformer and EfficientNet (UNet3+STE) was based on the structure of UNet3+, with the encoder sequentially combining EfficientNet based on mobile inverted bottleneck convolution (MBConv) and the Swin Transformer. By sequentially utilizing convolutional neural networks (CNNs) and transformer layers, the proposed algorithm aimed to extract the local and global information of cloud regions effectively. In addition, the decoder used MBConv to restore the spatial information of the feature map extracted by the encoder and adopted the deep supervision strategy of UNet3+ to enhance the model’s performance. The proposed model was trained using the open dataset derived from KOMPSAT-3 and 3A satellite imagery and conducted a comparative evaluation with the state-of-the-art (SOTA) methods on fourteen test datasets at the product level. The experimental results confirmed that the proposed UNet3+STE model outperformed the SOTA methods and demonstrated the most stable precision, recall, and F1 score values with fewer parameters and lower complexity.

The tripartite evolutionary game of enterprises' green production strategy with government supervision and people participation

Government supervision and people participation play vital roles in enterprises' green production strategy, but few studies have considered the strategy choices behind government supervision and people's participation. This study contended that whether an enterprise adopts the green production strategy is influenced not only by its responsible attitude facing social responsibility but also by the following two factors, the intensity of government supervision and whether people choose to participate in supervision or not when facing the enterprise adopting the green production strategy or not. We constructed a tripartite evolutionary game model to explore the behavioral evolution rules and evolutionary stability strategies of government supervision, people participation, and enterprises' green production. Then we employed numerical simulation to analyze how various factors influence the strategy selection of the government, people, and enterprises. The results show that if the utility values of government supervision and people participation are greater than 0, the enterprises will adopt the green production strategy. The system stability is affected by a synergistic relationship between participation cost, reputation benefit, and government subsidies, and an incremental relationship between enterprises' green production benefit, government subsidies, people's reported bonus, and enterprises' green production cost. This study provides a new theoretical perspective for research on government supervision, people participation, and enterprises' green production strategy, and the results provide important references for improving the enterprises' green production and urban environmental management.

Associations of Racial Equity Training, Policies, and Practices With Routine Supervision Strategies in Community Corrections

Community corrections agencies across the United States are adopting racial equity as a priority in their polices, practices, and staff training, though how racial equity can be translated into the routine practices of probation and parole officers has not been widely discussed. This study examines the associations of perceived racial equity priorities on the supervision strategies reported by probation and parole officers in an online survey ( N = 1054). Approximately one-third of officers reported that their agencies prioritized racial equity. Racial equity scores were stronger in juvenile agencies and in agencies that prioritized evidence-informed practices. Racial equity was associated with reduced accountability-oriented case management practices. Results of this study suggest that racial equity policies and practices may impact client outcomes through changes in general supervision strategies. More research is needed to identify race-conscious strategies that community corrections officers can employ to meet the needs of people involved in the legal system.

Clean energy ship application to promote carbon neutrality in global maritime industry: State governance or international supervision？

The global maritime industry is facing the goal to achieve "carbon neutrality", and substituting traditional ship fuel with clean energy is the most important solution. Whether to promote clean-energy ships through state governance or unified international supervision to achieve carbon neutrality has been a long-standing debate. This study employs both a tripartite evolutionary game model and a quadrilateral evolutionary game model to compare the effectiveness of state governance and unified international supervision in promoting clean-energy ships. The tripartite model simulates interactions between local governments, shipping companies, and shippers, revealing that high subsidy costs reduce local governments' incentives to promote clean-energy ships. The quadrilateral model introduces international supervision, demonstrating that a unified international oversight mechanism can accelerate the global maritime industry's progress toward carbon neutrality. Numerical simulations indicate that lowering the purchase costs of clean-energy ships and introducing government subsidies significantly influence the adoption of clean-energy ships, while supervision costs impact the effectiveness of international regulations. These findings provide critical insights for policymakers aiming to balance financial incentives and global supervision strategies to foster low-carbon development in the maritime sector.

The Supervisory Relationship and Contextual Stressors

The effectiveness of supervision throughout the student writing process depends on several key factors: regular academic meetings, transparent expectations, progress documentation, and the cultivation of an inclusive research environment. To effectively address unconscious biases and inequities within the supervisory relationship, a gender-responsive approach is crucial. Implementing gender-sensitive supervision strategies is essential for mitigating the negative effects of gender-based interaction patterns on supervisees, which, in turn, enhances the overall quality of research. By fostering a more equitable supervisory environment, these strategies contribute to improved outcomes and a more supportive research process.

Improving image-based weld defects detection under interference information via a novel semantic supervision strategy

ABSTRACT Weld defects of skin-skeleton structures are invisible and image-based visual inspections using deep learning neural networks are in demand. The main limitation of previous detection algorithms is interference information in images. The reflective light and uneven brightness distribution hinder algorithms to achieve higher detection reliability. In this work, a novel supervision strategy for defects detection algorithms was proposed to break the limitation. A new semantic gate convolution block was developed to help the neural networks to distinguish between targets and interference. The block utilised semantic segmentation labels and a gate function to control the information transmitted to the detection output. Additionally, a new category-pixel-accuracy loss function was adopted to improve the effectiveness of semantic features. The new function reduced the effects of negative pixels to avoid over emphasis on semantic completeness, thus the ineffective features of interference could be eliminated. The results indicated that the back-propagated gradients from the supervision part taught the backbone networks to focus on correct objects instead of interference. To testify the validity of the current method, the algorithms was verified in burns and collapse defects. The detection accuracy under the new semantic supervision reached 99.1%, which was superior to common CNN.
