Terrain-Adaptive Mobile 3D Printing with Hierarchical Control

Shuangshan Nors Li, J. Nathan Kutz

Mobile 3D printing on unstructured terrain remains challenging due to the conflict between platform mobility and deposition precision. Existing gantry-based systems achieve high accuracy but lack mobility, while mobile platforms struggle to maintain print quality on uneven ground. We present a framework that tightly integrates AI-driven disturbance prediction with multi-modal sensor fusion and hierarchical hardware control, forming a closed-loop perception-learning-actuation system. The AI module learns terrain-to-perturbation mappings from IMU, vision, and depth sensors, enabling proactive compensation rather than reactive correction. This intelligence is embedded into a three-layer control architecture: path planning, predictive chassis-manipulator coordination, and precision hardware execution. Through outdoor experiments on terrain with slopes and surface irregularities, we demonstrate sub-centimeter printing accuracy while maintaining full platform mobility. This AI-hardware integration establishes a practical foundation for autonomous construction in unstructured environments.

High-resolution 3D-printed plastic scintillators with tertiary dye

Chandler Moore, Michael Febbraro, Juan Manfredi et al.

Additive manufacturing offers efficient production of plastic scintillators with nontrivial geometries using vat polymerization, allowing fabrication of geometries which would be difficult or even impossible to produce using conventional subtractive manufacturing. This work presents a novel photocurable scintillator formula that includes coumarin 450 as a tertiary dye to enable high-resolution 3D printing via the manipulation of the 405 nm cure light. Bulk photocured and 3D printed (with and without tertiary dye) samples were compared through observational assessment and spectral response. All samples showed pulse shape discrimination between neutron and gamma events. Inclusion of the tertiary dye has minimal impact on emission spectrum and light output, but significant impact on print resolution as shown by comparison of printed high-complexity geometries and feature resolution test objects. With the use of a cure-limiting dye, unsupported features, such as freestanding pillars, were resolvable down to 0.7 mm. Even finer resolution at or below 0.1 mm was achieved in fully supported, integrated structures printed with off-the-shelf 405 nm desktop 3D printer. Scintillators demonstrated a light output up to 50% of EJ-200 with a PSD figure of merit up to 1.35 at 0.9-1.1 MeVee.

Scrolly2Reel: Retargeting Graphics for Social Media Using Narrative Beats

Duy K. Nguyen, Jenny Ma, Pedro Alejandro Perez et al.

Content retargeting is crucial for social media creators. Once great content is created, it is important to reach as broad an audience as possible. This is particularly important in journalism where younger audiences are shifting away from print and towards short-video platforms. Many newspapers already create rich graphics for the web that they want to be able to reuse for social media. One example is scrollytelling sequences or "scrollies" -- immersive articles with graphics like animation, charts, and 3D visualizations that appear as a user scrolls. We present a system that helps transform scrollies into social media videos. By using the scriptwriting concept of narrative beats to extract fundamental storytelling units, we can create videos that are more aligned with narration, and allow for better pacing and stylistic changes. Narrative beats are thus an important primitive to retargeting content that matches the style of a new medium while maintaining the cohesiveness of the original content.

Mainstreaming and Weaponizing Satire in Nigerian Journalism Practice

Jude Nwakpoke Ogbodo, Emmanuel Chike Onwe, Blessing Ewa-Ibe et al.

Satire has gained increased scholarly traction across journalism and related fields. The genre increases the entertainment value of journalism and broadens its appeal. Satirical news also serves as a catalyst to pique the curiosity of ordinarily disinterested audiences in news, particularly political news. However, there are some concerns emerging from the weaponization of satire in this contemporary period, which is characterised by the proliferation of fake news and misinformation. From the Nigerian context, there have been minimal empirical spotlights placed on satirical journalism. We employed semi-structured interviews to explore the views of Nigerian print satirical journalists and cartoonists. Our finding broadens scholarship in the evolving area of satirical journalism. It demonstrates how the mainstreaming and the weaponization of satire have changed the texture of satire in Nigerian journalism. Although ethical concerns are admitted, we argue that cartoonists and satirical journalists have a responsibility to adjust to the dynamic media ecology, where satire continuously provides insightful critique and entertaining commentaries.

Feminisation of Extremism as a Socio-Psychological Phenomenon

Ainura Bolysbayeva, Zharkynbek Abikenov, Aigerim Bolysbayeva et al.

Today, religious extremism, transforming and evolving, has appeared before the world community in a new form of feminist extremism. Since the radicalisation of women affects all levels of society, from everyday life to political institutions, this problem is the most pressing at present. Therefore,  this study aims to make a socio-psychological portrait of a female terrorist. The article analysed video and print interviews of six women who were convicted under the article "Terrorism". In order to fully consider this problem, media materials devoted to these women were studied. The study explored the history of feminisation of extremism, its impact on society, and methods of prevention, as well as constructed a sociological portrait of a woman influenced by extremism and indicated her motives for radicalisation. The obtained data can be used to create programmes to counter extremism and terrorism, gathering information for public lectures.

Migrant Multimodal Narratives: From Blogs and Print Media to YouTube

Maria Festa

Current technology places migrant narratives into a fresh, diverse and at times hybrid act of narrating. Due to the proliferation of digital media and global culture, migrants’ journeys are frequently documented through various multimodal forms. The impact of new media on the body of current migrant narratives – particularly those that fall under the canon of postcolonial literature – will be explored in the works of Chimamanda Ngozi Adichie, Reni Eddo-Lodge and Warsan Shire. This chapter also aims at highlighting how current technology is increasingly used as a means for people to tell their stories, so that their voices can be heard by a wider citizenship and most relevantly therefore might be used as advocacy tools for a cause.

Contrastive Attention Networks for Attribution of Early Modern Print

Nikolai Vogler, Kartik Goyal, Kishore PV Reddy et al.

In this paper, we develop machine learning techniques to identify unknown printers in early modern (c.~1500--1800) English printed books. Specifically, we focus on matching uniquely damaged character type-imprints in anonymously printed books to works with known printers in order to provide evidence of their origins. Until now, this work has been limited to manual investigations by analytical bibliographers. We present a Contrastive Attention-based Metric Learning approach to identify similar damage across character image pairs, which is sensitive to very subtle differences in glyph shapes, yet robust to various confounding sources of noise associated with digitized historical books. To overcome the scarce amount of supervised data, we design a random data synthesis procedure that aims to simulate bends, fractures, and inking variations induced by the early printing process. Our method successfully improves downstream damaged type-imprint matching among printed works from this period, as validated by in-domain human experts. The results of our approach on two important philosophical works from the Early Modern period demonstrate potential to extend the extant historical research about the origins and content of these books.

4D-Printing of Smart, Nacre-Inspired, Organic-Ceramic Composites

Benedikt F. Winhard, Philipp Haida, Alexander Plunkett et al.

Additive manufacturing of shape memory polymers has gained tremendous interest in recent years due to their versatile potential applications in various industries, such as biomedicine and aerospace. However, the polymers' mechanical properties, specifically stiffness and strength, often hinder their use in mechanically demanding applications, e.g. as structural materials. In this work we produced nacre-inspired composites with a covalent adaptable network, which enables fast and mechanically lossless self-healing, reshaping, and shape memory capabilities. We demonstrate a novel direct write 4D-printing strategy to print smart, nacre-inspired, organic-ceramic composites based on alumina platelets and vitrimers with up to 3.3 and 26.7 times higher tensile strength and stiffness, respectively, in comparison to the pristine vitrimer. To the best of our knowledge, we introduce for the first time a single step 4D-printing process for nacre-inspired composites, that exploits suspension spreading to align micron sized alumina platelets along a common plane, and which utilizes solvent evaporation to induce polycondensation of the monomers resulting in a vinylogous urethane vitrimer after extrusion of the suspension. This work presents a facile, direct write 4D-printing strategy at ambient printing conditions, establishing a foundation for adaptive additive manufacturing of smart organic-ceramic composites of interest to various industries.

Multi-Institutional Audit of FLASH and Conventional Dosimetry with a 3D-Printed Anatomically Realistic Mouse Phantom

M Ramish Ashraf, Stavros Melemenidis, Kevin Liu et al.

We conducted a multi-institutional audit of dosimetric variability between FLASH and conventional dose rate (CONV) electron irradiations by using an anatomically realistic 3D-printed mouse phantom. A CT scan of a live mouse was used to create a 3D model of bony anatomy, lungs, and soft tissue. A dual-nozzle 3D printer was used to print the mouse phantom using acrylonitrile butadiene styrene ($~1.02 g/cm^3$) and polylactic acid ($~1.24 g/cm^3$) simultaneously to simulate soft tissue and bone densities, respectively. The lungs were printed separately using lightweight polylactic acid ($~0.64 g/cm^3$). Hounsfield units (HU) and densities were compared with the reference CT scan of the live mouse. Print-to-print reproducibility of the phantom was assessed. Three institutions were each provided a phantom, and each institution performed two replicates of irradiations at selected mouse anatomic regions. The average dose difference between FLASH and CONV dose distributions and deviation from the prescribed dose were measured with radiochromic film. Compared to the reference CT scan, CT scans of the phantom demonstrated mass density differences of $0.10 g/cm^3$ for bone, $0.12 g/cm^3$ for lung, and $0.03 g/cm^3$ for soft tissue regions. Between phantoms, the difference in HU for soft tissue and bone was <10 HU from print to print. Lung exhibited the most variation (54 HU) but minimally affected dose distribution (<0.5% dose differences between phantoms). The mean difference between FLASH and CONV from the first replicate to the second decreased from 4.3% to 1.2%, and the mean difference from the prescribed dose decreased from 3.6% to 2.5% for CONV and 6.4% to 2.7% for FLASH. The framework presented here is promising for credentialing of multi-institutional studies of FLASH preclinical research to maximize the reproducibility of biological findings.

Can social media be a tool for reducing consumers’ food waste? A behaviour change experiment by a UK retailer

W. Young, S. Russell, Cheryl A. Robinson et al.

This paper reports on a landmark study to field-test the influence of a large retailer to change the behaviour of its millions of customers. Previous studies have suggested that social media interaction can influence behaviour. This study implemented three interventions with messages to encourage reductions in food waste. The first was a social influence intervention that used the retailer’s Facebook pages to encourage its customers to interact. Two additional information interventions were used as a comparison through the retailer’s print/digital magazine and e-newsletter. Three national surveys tracked customers’ self-reported food waste one month before as well as two weeks after and five months after the interventions. The control group included those who said they had not seen any of the interventions. The results were surprising and significant in that the social media and e-newsletter interventions as well as the control group all showed significant reductions in self-reported food waste by customers over the study period. Hence in this field study, social media does not seem to replicate enough of the effect of ‘face-to-face’ interaction shown in previous studies to change behaviour above other factors in the shopping setting. This may indicate that results from laboratory-based studies may over-emphasise the effect of social media interventions.

Awarding of Citizenship to Afghan and Bengali Refugees: a Comparative Analysis of Pakistan's Print and Social Media Frames

Qaisar Khan, Sher Akbar, Zaid Bin Inam

This research focuses on the framing of Afghan and Bengali refugees in the mainstream print and social media as a result of the announcement made by the Prime Minister of Pakistan, Imran Khan, for awarding citizenship to both Afghan and Bengali refugees. A comparative analysis explores the cross-media examination of print and social media framing regarding the respective issue. The results of the quantitative content analysis revealed that social media adopted more pro-citizenship frames by portraying the refugees as compared to the print media, which employed more anti-citizenship frames. Furthermore, the research highlights that social media adopted more humanitarian and legal framework topics to lay emphasis on the suffering of refugees. The Urdu newspapers framed the Afghan and Bengali citizenship issue in a more pro-citizenship manner as compared to the English newspapers. The mainstream print media employed more unfavorable frames to accentuate the refugees as an economic burden, as compared with the social media.The political apprehension and burden on the economy is the foremost rationale for the aversion to granting citizenship rights to the refugees.

Anomaly localization for copy detection patterns through print estimations

Brian Pulfer, Yury Belousov, Joakim Tutt et al.

Copy detection patterns (CDP) are recent technologies for protecting products from counterfeiting. However, in contrast to traditional copy fakes, deep learning-based fakes have shown to be hardly distinguishable from originals by traditional authentication systems. Systems based on classical supervised learning and digital templates assume knowledge of fake CDP at training time and cannot generalize to unseen types of fakes. Authentication based on printed copies of originals is an alternative that yields better results even for unseen fakes and simple authentication metrics but comes at the impractical cost of acquisition and storage of printed copies. In this work, to overcome these shortcomings, we design a machine learning (ML) based authentication system that only requires digital templates and printed original CDP for training, whereas authentication is based solely on digital templates, which are used to estimate original printed codes. The obtained results show that the proposed system can efficiently authenticate original and detect fake CDP by accurately locating the anomalies in the fake CDP. The empirical evaluation of the authentication system under investigation is performed on the original and ML-based fakes CDP printed on two industrial printers.

Current Trends of the Development of Creative Industries and Their Impact on the National Economy

Nataly Martynovych, Serhii Plutalov

Despite the rapid development of technologies, increasing data volumes, the development of the Internet and robotics, the spread of machine learning and artificial intelligence, there is something that a person manages much better than the most advanced machines and contributes to economic growth on the basis of sustainable development, improving the quality of life of the population while preserving natural potential. Everyone is born with this extraordinary ability called "creativity." Therefore, first of all, the state should be interested in the development of the creative sector of the economy and should support it in every possible way. Considering that the purpose of the article is to establish trends in the development of creative industries in Ukraine and determine their impact on the national economy. Based on the analysis of official statistical information, key trends are identified, the essence of which comes down to the rapid growth of the creative economy in most socio-economic indicators. It is proved that the Covid-19 pandemic has destabilized the stability of the trend of development of creative industries, however, the decline in indicators in the context of other types of economic activity is not significant, and they tend to recover quickly and steadily increase. The most vulnerable sectors of creative industries have been identified. The influence of creative industries on the national economy is argued. The prospects for further research are outlined, which consist in the activation of the development of performing arts (live music, theatre, dance, opera, circus, puppet theatre); literature, publishing and print media; architecture, since they have a great influence on the national economy due to their direct contact with the broad masses – the population and a close intersectoral connection with other industries.

Exposure to Cannabis Marketing in Social and Traditional Media and Past-Year Use Among Adolescents in States With Legal Retail Cannabis.

J. Whitehill, P. Trangenstein, Marina C. Jenkins et al.

PURPOSE The objective of this study was to examine adolescents' self-reported exposure to cannabis marketing in states with legalized cannabis and its association with past-year cannabis use. METHODS We conducted a cross-sectional, online panel survey of 469 adolescents aged 15-19 years residing in four states with legal retail cannabis for adult use. Adolescents self-reported exposure to cannabis marketing on social or traditional media (i.e., outdoor or print) and past-year cannabis use. Logistic regression generated estimated odds of youths' past-year cannabis use by marketing exposure after adjusting for demographic factors and cannabis-related social norms. RESULTS Exposure to cannabis marketing on Facebook, Twitter, and Instagram was associated with increased odds of past-year cannabis use of 96% (95% confidence interval [CI]: 15%-234%), 88% (95% CI: 11%-219%), and 129% (95% CI: 32%-287%), respectively. Odds of past-year cannabis use increased by 48% (95% CI: 16%-87%) with each additional social media platform where adolescents reported exposure. CONCLUSIONS Despite restrictions that prohibit cannabis advertising on social media, adolescents are exposed to cannabis marketing via social media, and this exposure is associated with recent cannabis use. States should consider further regulation of cannabis marketing on social media.

A New Age for Media Coverage of Women’s Sport? An Analysis of English Media Coverage of the 2015 FIFA Women’s World Cup

Kate Petty, S. Pope

This article examines English print media coverage of the England national women’s football (soccer) team during the 2015 FIFA Women’s World Cup. It draws on a content analysis of five English national newspapers from 24 May to 14 August 2015. A wide body of research has demonstrated that women’s sport continues to be greatly underrepresented in the media but our findings are important as they demonstrate that during this tournament, women’s football received a significant amount of print media coverage and that this coverage was largely positive. We argue that we have entered a new age of media coverage of women’s sport in the UK, with a shift towards greater gender equality.
