Abstract
Reconstructive surgery following breast cancer ablation is a surgical gold standard and of increasing importance, but current options comprising autogenous fatty tissue transfer and artificial soft tissue implants are inferior. With the advent of powerful biofabrication technologies like bioprinting, researchers for the first time have the tools to engineer life-like tissues with the ultimate goal of clinical application. In this work, we apply multi-material stereolithographic bioprinting together with a novel sacrificial biomaterial system to engineer complex fatty tissue constructs. Biomaterials, cellular composition and cultivation conditions of these constructs were designed to enable in vitro creation of vascularised fatty tissue. Cells within the constructs showed an overall good survival (>93%) indicated by Calcein-AM staining for living cells and cytotoxicity levels below 7 % (PI-positivity), which even decreased during The constructs showed highay significant increase in cellular viability and activity overthe entire cultivation the culture period of 27 days. Bioprinted aAdipose-derived stem cells were successfully differentiated into adipocytes in situ and expressed PPARy as well as FABP4. Additionally, secretion of adipokines leptin and adiponectin into culture supernatants increased significantly. Endothelial cells vascularised the constructs, creating macro- and microvascular structures within the printed channels and extending beyond with culture time. Multi-modal imaging revealed dynamic cell activitymigration of cells within the bioprinted constructs and signs of progressing maturation towards fatty tissue. Moreover, cells invaded into the surrounding hydrogel. The engineered fatty tissue constructs could serve as a base to develop patient-specific tissue building blocks with the final goal to achieve an all-natural reconstruction of the breast.

Abstract
3D bioprinting is rapidly evolving as a transformative technology for constructing biological tissues with precise cell and bioink placement. However, ensuring the quality and viability of bioprinted structures presents significant challenges, highlighting the need for advanced monitoring systems. Our study introduces a space-efficient, non-invasive approach for real-time, in-situ monitoring of cell dispersion in bioprinted constructs. Utilizing a novel in-situ fluorescence microscopy technique, we employ nanoparticles for cell tagging and integrate a compact digital microscope into the bioprinter for layer-by-layer imaging, significantly saving space and weight to make the solution adaptable to any commercial bioprinter. This method enhances in-situ analysis by combining data from the fluorescence system with conventional visible spectrum imaging. The synergy of these datasets provides a detailed method to examine cell dispersion and facilitates continuous monitoring during the bioprinting process. This allows for the immediate identification and correction of irregularities in cell deposition. Our approach aims to advance 3D bioprinting, setting new standards for the reliability and efficiency of bioprinted structures.
Propagation of optical pulses in a spatiotemporal dispersive medium
Authors: Agrawal Govind P 
Published: February 2025

Abstract
This review focuses on novel phenomena that emerge when optical pulses propagate through a spatiotemporal dispersive medium whose refractive index is modulated, both in space and time, in a traveling-wave fashion. Using optical fibers as an example of a dispersive medium, we first derive an equation governing the evolution of short pulses in such a medium. This equation is used to discuss the phenomena such as temporal reflection and refraction, total internal reflection, and waveguiding from a moving boundary with different refractive indices on its two sides. The use of solitons, forming through the Kerr effect, shows how such effects can be observed with silica fibers by employing a pump-probe configuration. A pair of solitons provide the temporal analog of a waveguide or a Fabry–Perot resonator. A new kind of grating, called a spatiotemporal Bragg grating, is formed when a train of pump pulses creates periodic high-index regions inside an optical fiber moving at the speed of pump pulses. The interaction of probe pulses with such a Bragg grating is studied both within and outside of momentum gaps. It is also shown that a photonic analog of Anderson localization is possible when disorder is introduced into a spatiotemporal Bragg grating.

Published: February 2025

Abstract
In this research work, the fiber modes supported by the graphene-wrapped indium antimonide nanowire have been examined theoretically. The indium antimonide (InSb) is a semiconductor material, which has temperature-sensitive optoelectronic properties. To model the nanowire of InSb, Drude’s model has been used for better results. The Kubo’s formalism based on the random phase approximation is used for the modeling of graphene. The impedance boundary conditions (IBCs) are used to compute the characteristic equations. The real and imaginary part of permittivity of InSb as function of THz frequency under different values of temperature T∈[200 K,400 K] has been computed. It is reported that the InSb shows the temperature dependent metal-insulator phase transition i.e., for temperature T≤200K it behaves as insulator and for T> 200K it acts as metal. The numerical results for dispersion relation, propagation band, propagation losses, cut off frequency range, effective mode index and field profiles have been presented for insulator as well as metallic phase of InSb. Moreover, the impact of chemical potential, radius, and temperature on fiber mode characteristics has been analyzed. The computed numerical results can be applied for designing tunable temperature assisted nano waveguides, thermo-optical sensing probes, thermal imaging and near-field communication devices in THz frequency range.
A deep learning approach for predicting and optimizing the V2X network parameters for sustainable smart transportation systems
Authors: Vinodhini M , Rajkumar Sujatha 
Published: February 2025

Abstract
The increasing prevalence of automated vehicles necessitates robust vehicle-to-everything (V2X) communication systems. However, challenges such as latency, reliability, transmission rates, data collisions, and security vulnerabilities require thorough investigation. To address these issues, this study proposes a deep learning-based hybrid model integrating long short-term memory (LSTM) neural networks and generative adversarial networks (GANs) to predict performance metrics in V2X communication networks. The GANs augment the sample vehicular dataset and facilitate proactive vehicular network management. The proposed approach comprises three key phases: data augmentation, feature extraction, and predictive analysis. To optimize the neural parameters, the whale optimization algorithm (WOA) is utilized and benchmarked against other optimization algorithms, including beetle swarm optimization, artificial bee colony optimization, and pelican optimization. The parameters in the developed hybrid GAN-LSTM model and autoencoder were tuned using the WO algorithm to minimize key performance metrics such as the mean absolute error, root mean square error, bit error rate, and mean square error. Results indicate that the predictive model enhances the sustainability and efficiency of transportation systems by accurately forecasting critical metrics, including latency, throughput, and reliability, within V2X networks.
On the sampling sparsity of analog-to-spike conversion based on leaky integrate-and-fire
Authors: Moser Bernhard , Lunglmayr Michael 
Published: February 2025

Abstract
In contrast to the traditional principle of periodic sensing, neuromorphic engineering pursues a paradigm shift towards bio-inspired event-based sensing, where events are primarily triggered by a change in the perceived stimulus. We show in a rigorous mathematical way that information encoding by means of Threshold-Based Representation based on either Leaky Integrate-and-Fire (LIF) or Send-on-Delta (SOD) is linked to an analog-to-spike conversion that guarantees maximum sparsity while satisfying an approximation condition based on the Alexiewicz norm.&#xD;

Abstract
Tropical forests harbor much of Earth’s biodiversity, with the ground to emergent canopy forming a dynamic three-dimensional habitat. Arboreal and semi-arboreal species navigate this vertically heterogeneous environment, responding to diel, lunar, and seasonal changes. While diel vertical migrations are well studied in aquatic systems, similar patterns in arboreal mammals and birds remain unclear. Temperature, light, predation risk, and resource availability varies from ground to canopy, across time, and influences unique 3D movements for diverse arboreal species. Yet their roles in structuring tropical forest assemblages, the interactions of vertical stratification and temporal niche partitioning, is poorly understood. We investigate diel vertical behaviors in 31 species of arboreal mammals and birds in the Madre de Dios region of Peru using ground and canopy camera trapping surveys. We assess diel-vertical overlaps among sympatric species and examine relationships between dietary traits and vertical preference and selectivity for mammals. Our results reveal many unique patterns of vertical shifts, with many Primates and couple Cracids descending from crepuscular canopy activity to lower strata at midday, while Tamandua tetradactyla descends from sunrise to sunset and Choloepus hoffmanni from before to after midnight. Lagothrix lagothricha and Pithecia spp. displayed peaks in upper canopy activity at midday, possibly due to ecological release from other primates. We find high diel-vertical overlap between sympatric species pairs, suggesting niche partitioning may involve finer-scale temporal adjustments rather than strict vertical segregation. We also find patterns of lunar cycle-related shifts in vertical activity for Tamandua tertradactyla, Choloepus hoffmanii and Aotus nigriceps. Diet-related patterns in mammals indicate carnivores favor lower heights, frugivores prefer higher strata, and invertivores are more vertically variable. These findings challenge static views of vertical stratification, emphasizing the need for a framework integrating temporal and spatial variability in the vertical environment and its many biotic agents. Better understanding these patterns is crucial for predicting arboreal species and community responses in their warming, fragmenting and increasingly peri-urban habitats.
Linguistic rights
Authors: Coulmas Florian 
Published: February 2025

Abstract
Reacting to an increasing number of languages that fell into disuse over recent decades, the United Nations General Assembly has proclaimed the period between 2022 and 2032 as the International Decade of Indigenous Languages. This chapter is focussed on the socio-economic developments leading to the decline and abandonment of Indigenous languages and the policy responses to them. It examines the world’s linguistic diversity as it is today, future projections about it, and the ideological transformations that have turned the fate of minority languages into a policy issue on international and national levels. Key issues discussed in this context are minority protection and linguistic rights and whether the bearers of such rights are individuals or groups.
Variae Recitationes
Authors: Vidas Moulie 
Published: February 2025

Abstract
Discussions of textual divergences, what we may call “versions” or “variants,” are common in the Talmud. This chapter argues that these discussions presented a new development in rabbinic scholarship. Much like Greek and Latin scholars compared different copies or editions of the same work, Amoraic scholars compared different recitations of the same teaching, introducing a discourse of “variant readings” with a particular inflection into the study of Torah. While these discussions have been read as evidence for the formation of the Mishnah, this chapter focuses on how they reflect the aims and ideas of Amoraic scholars. These scholars considered recited teachings as alternative attestations of still other recited teachings, but they avoided placing these divergent texts in a hierarchy with each other or even with a hypothesized original. The comparison of Amoraic, other Greco-Roman, and modern discussions of textual difference highlights how such discussions are shaped by different ideas and aims.
Introduction
Authors: Noggle Robert 
Published: February 2025

Abstract
This chapter introduces the topic and book. It begins by noting the importance of influence in human life. It observes that manipulation is normally distinguished from other forms of influence such as rational persuasion, bargaining, and coercion. It distinguishes ordinary manipulation, which is common in everyday life, from extra-ordinary forms of influence that are called ‘manipulation’ in the free will literature. It also distinguishes personal from situational manipulation. It notes that the term ‘manipulation’ has definite negative moral connotations when used in ordinary conversation. It poses three questions about manipulation: What is it? How does it work? Why is it (apparently) bad? It sets out and explains a version of the methodology of reflective equilibrium for investigating manipulation and answering these questions. It concludes with a plan of the book and some terminological preliminaries.
Mistakes and Manipulation
Authors: Noggle Robert 
Published: February 2025

Abstract
This chapter details the various sorts of mistakes the induction of which the Mistake Account regards as manipulation. It begins with mistaken beliefs. A belief is mistaken when it is false. Emotions can be mistaken either by failing to fit the facts (as when Othello is jealous of Desdemona despite having no reason for jealousy) or by being too strong or too weak for the circumstances (as when someone is excessively fearful of a small, well-behaved dog). Mistakes of attention and weighting occur when the amount of attention paid to some fact, or the amount of weight placed on it in decision-making, is disproportionate to its actual importance. Other sorts of mistakes involve the application of heuristics or packages of procedural knowledge in situations where they are not appropriate. The mistakes involved in manipulative pressure are also discussed. These are instances of what philosophers call akrasia or weakness of will.
Hair Straighteners
Authors: Barylo William 
Published: February 2025

Abstract
Whiteness is a spectrum. It is a set of norms that ethnically minoritized people can either adopt by assimilation, de-diasporization, or westernization, or which they resist and with which they compromise. In the era of metacolonialism, just like with the symbolic tool for European beauty standards, diasporas have been served different metaphorical hair straighteners, tools of normative pressure with which colonial powers assert their domination. Political narratives, popular culture, social media, and celebrities have created a theology of liberation based on Eurocentric aspirational standards of beauty and socio-economic status. When being different is a risk, conformity becomes safety, at the risk of losing one’s identity or replicating harmful behaviours like colourism or racism.
Eastern Europe
Authors: Michal Pawlak Stanislaw 
Published: February 2025

Abstract
This chapter addresses broad aspects of the influence of Eastern Europe on the development and implementation of the law of the sea, focusing on Poland and Lithuania from the Baltic Sea region and Bulgaria and Romania on the Black Sea. Eastern Europe reflects the legal, economic, political, and military dimensions of cultural experiences between Western Europe and Russia. Poland, Lithuania, Bulgaria, and Romania experienced a complicated history of foreign domination and were heavily influenced by Western European legal culture derived from Roman law. They finally joined the mainstream of the development of the law of the sea and aligned with Western Europe. Historically, Eastern European states promoted freedom of navigation and access to the living resources on the high seas as a function of their geographically disadvantaged position and restricted access to the open ocean. In this respect, these states had a geographic alignment with Russia. They also advanced the principles of exploitation of the seabed minerals in the areas beyond national jurisdiction to ensure an equitable share of the riches of the international seabed area, a shift away from Western Europe and siding with the interests of developing states. Poland and Lithuania maintained historic efforts to get free access to the sea. For Poland, located between Germany and Russia, the access to the Baltic Sea was a vital necessity and a driving force of economic development and security.
Africa
Authors: Pasipanodya Tafadzwa 
Published: February 2025

Abstract
African culture reflects the concept of ubuntu or moral worth through community, the colonial experience, and quest for economic independence, among other influences. Ubuntu is a word in the Southern African languages of Zulu, Xhosa, and Ndebele that expresses the notion that an individual’s humanity is inextricably connected to the group to which they belong. The philosophy considers that the duty to relate humanely with others is a prerequisite to one’s own personhood, placing a connection with other people at the centre of human life. These values have informed Africa’s approach to international law, which from the outset was viewed by many Africans as a flawed legal order tantamount to legalized colonialism. At independence, African states chose to adapt rather than reject the international legal system in order to redress some of the most debilitating socio-economic effects of colonialism, help them regain control over their natural resources, and prevent future aggression and exploitation. These experiences underpin African states’ substantive contributions to the contemporary law of the sea. Whereas the traditional maritime powers focused on freedom of the seas, the sense of community in African states informed their support for the common heritage of mankind in deep seabed mining, the transfer of marine technology and capacity-building, and the influential 1973 Kenyan paper on the elements of an exclusive economic zone beyond the territorial sea.
North America
Authors: Kraska James 
Published: February 2025

Abstract
North American cultural influences on the law of the sea derive primarily from European approaches, principally Dutch, English, and German, tempered by the influence of Mediterranean cultures. American culture was affected by the isolated geography of the colonies and their role as a sideshow in European power struggles and wars. From this experience, a culture of rugged independence and self-sufficiency emerged. North America had a small population and virtually limitless natural resources. These resources contributed to strong, independent communities free from central control, immense economic opportunity, and a desire to purchase finished products from Europe. The expansion of trade and independence was fuelled by concepts of liberty and autonomy, optimism, and control of destiny. In the nineteenth and twentieth centuries, as the United States emerged as a superpower. The United States maintained connections with Europe and Asia through continued reliance on the doctrine of freedom of the seas. At the same time, the rise of the administrative state and a mixed economy after the Great Depression and the industrial importance of offshore oil and fisheries directed American attention towards coastal state equities. By the 1970s, the United States added protection of the marine environment to its core oceans governance priorities, reflecting a post-modernist mindset and complicating the historic advocacy of freedom of the seas. These values have become the dominant focus of contemporary US oceans law and policy.
Conclusion: Historical Legacies and Future Prospects

Published: February 2025

Abstract
This volume explored the historical arc and contemporary manifestation of cultural influences on the law of the sea and oceans governance. The chapters have analysed major cultural touchpoints of world civilizations and how they have shaped and continue to impact the law. The Global North–South dialogue is one of the most important reflections of these cultural approaches. Individual contributions have offered assessments of the benefits of the major cultural approaches and how they would further shape global oceans law and policy should the regional cultural preferences be widely adopted. The chapters find that regardless of cultural values or other elements such as geography, level of economic development, or type of political system, states have contending visions as well as commonalities in how the law of the sea is developed. Yet distinct cultural norms emerged from Christianity, Roman law, the concept of the freedom of the seas on the one hand and ubuntu and harmonious hierarchy and Asian social order on the other. Which cultural values in the law of the sea should be adopted, and why and how would they benefit sovereign states as well as all humankind?
