Cultural heritage documentation increasingly relies on image-based 3D surface reconstruction, with photogrammetry software making such workflows accessible to archaeologists, conservators, and heritage technicians. These tools have been successful for conventional multi-view acquisition, but they do not routinely exploit richer multi-view, multi-light data, despite its potential for improving fine-scale surface reconstruction. This limitation is particularly relevant in heritage contexts, where controlled-light acquisition devices such as RTI domes are already used to capture illumination-varying image sets. The challenge is therefore to connect these existing acquisition practices with recent computer vision methods in a form that can be used within operational heritage workflows. In this work, we address this need by integrating state-of-the-art components from computer vision for multi-view, multi-light surface reconstruction into Meshroom, an open-source photogrammetry framework. Rather than proposing a new reconstruction algorithm, our contribution is to assemble and expose existing advanced methods, namely a complete photometric stereo ecosystem (calibrated, self-calibrated and universal), automatic object masking, and multi-view normal-and-reflectance integration, within a usable heritage-oriented workflow. The proposed system thus provides an intermediate software layer between computer vision research code and practical cultural heritage applications, making recent techniques easier to use and evaluate.
Recent unified multi-modal encoders align a wide range of modalities into a shared representation space, enabling diverse cross-modal tasks. Despite their impressive capabilities, the robustness of these models under adversarial perturbations remains underexplored, which is a critical concern for safety-sensitive applications. In this work, we present the first comprehensive study of adversarial vulnerability in unified multi-modal encoders. We find that even mild adversarial perturbations lead to substantial performance drops across all modalities. Non-visual inputs, such as audio and point clouds, are especially fragile, while visual inputs like images and videos also degrade significantly. To address this, we propose an efficient adversarial calibration framework that improves robustness across modalities without modifying pretrained encoders or semantic centers, ensuring compatibility with existing foundation models. Our method introduces modality-specific projection heads trained solely on adversarial examples, while keeping the backbone and embeddings frozen. We explore three training objectives: fixed-center cross-entropy, clean-to-adversarial L2 alignment, and clean-adversarial InfoNCE, and we introduce a regularization strategy to ensure modality-consistent alignment under attack. Experiments on six modalities and three Bind-style models show that our method improves adversarial robustness by up to 47.3 percent at epsilon = 4/255, while preserving or even improving clean zero-shot and retrieval performance with less than 1 percent trainable parameters.
Case report: Herein we present the case of a 33-year nulliparous woman at 21 weeks of gestation with mitral valve vegetation resulting from infective endocarditis. Due to the mother's critical condition caused by consecutive thromboembolic events, surgery with cardiopulmonary bypass was indicated. During surgery the fetus was monitored by a specialized obstetrician who repetitively measured the Doppler indices of the umbilical artery, Ductus venosus and uterine artery. Right after CO2 was insufflated into the operating area, the Doppler moni-toring showed an increased Pulsatility Index of the Umbilical artery right before fetal distress with bradycardia occurred. A subsequent maternal arterial blood gas analysis showed an acidosis with hypercapnia. Consequently, the CO2 insufflation was stopped and the gas flow on the Heart Lung Machine increased. After regaining ho-meostasis of acidosis, the Doppler Indices and fetal heart rate recovered. The remaining surgery and post-operative course were uneventful. At the 37 weeks of gestation a healthy boy was delivered by Cesarean section and at the age of two years, the neurodevelopment was assessed, which indicated normal development in mental cognition, language and motoric. This report presents a periodic Doppler examination of the maternal and fetal circulation during surgery on CPB while also discussing the possible impact of fetal monitoring in managing open cardiac surgery in pregnancy.
The current study aims to better understand influences on men within the UK Christian community on their engagement with pornography and prostitution. The authors utilized the Carnes (2012) survey to examine the landscape of sexual knowledge and behaviours, and to identify symptoms, and the propensity towards, “out-of-control sexual behaviour” among participants. Data from a survey sent to the Christian community through church networks and word of mouth was used for this study. Of the 491 men who participated, the majority (94%, 460) described their personal Christian faith as “strong.” Despite the Christian faith community's moral code of conduct, the survey results showed a gap in self-awareness and understanding of members’ thoughts, beliefs, and conduct. Although almost three-quarters (74%, 361) of participants viewed pornography negatively, nearly half (45%, 220) admitted to using pornography at least occasionally. Many participants (31%, 152) indicated that they learned about sex through watching pornography. The survey also revealed that 10% (51) of participants had engaged with a prostitute for sex. Additionally, 21% (105) of participants believed that erotic massage was not prostitution. Using the Carnes (2012) framework, the survey found that over half of the survey participants (53%, 258) had a propensity towards “out-of-control sexual behaviour.” In relation to the church, more than half (55%, 268) of participants knew other Christian men who used pornography, and 25% (125) feared church discipline if they shared their use of pornography and prostitution. These results suggest that more programs and information are needed within the Christian community to build a culture of trust and accountability among members regarding sexual issues.
Purpose The purpose of this paper is to understand the dual crisis in Sri Lanka during the pandemic. The health crisis was followed by democratic backsliding which directly impacted the fight for economic crime. The pre-pandemic political commitment to fight corruption is assessed with the pandemic environment and the policy decisions by the Government. Sri Lanka was a detailed case study of how politicians exploited the pandemic environment to suppress democracy and move their semi-autocratic agenda forward. However, Sri Lanka was not the only nation that faced such autocratic sentiments losing the democratic values. This paper discusses recommendations for improving the resources and investment to address economic crime in Sri Lanka. Design/methodology/approach Secondary data was used for the analysis introducing a theoretical framework referring to the work of Michel Foucault and Francis Fukuyama. The secondary data was used to develop an argument aligning political science with economic crime. Findings The Government disciplinary project launched during the pandemic directly impacted Sri Lankan democracy and structural changes made to the constitution. The heavy militarization was a sign of departure of long-cherished values of democracy in the country. Political clientelism backed by nepotism interfered with judicial independence and the fight against economic crime. Many accused, including those responsible for the largest corruption scandal, were not punished. The trust deficit has widened significantly between authorities and the public on fighting corruption in Sri Lanka. Research limitations/implications There are more factors for democratic backsliding than what is presented in this paper. The economic crime environment in Sri Lanka has many dimensions and the paper only highlights a few areas limiting to the secondary data available. Originality/value The paper discusses a unique perspective on how a pandemic could be misused to strengthen the autocratic rule and make structural changes to a nation, including constitution amendments. The pandemic environment was used to commit economic crime and suppress public opinion projecting the health crisis in the lockdown environment.
