subject: 530 Physik

description: The absorption and emission spectroscopic behaviour of the platinum complexed porphyrin PtOEP (platinum-octaethyl-porphyrin) is studied at room temperature. Liquid solutions, doped films, and a neat film are investigated. The absorption cross-section spectra including singlet–triplet absorption, the triplet–singlet stimulated emission cross-section spectra, the phosphorescence quantum distributions, the phosphorescence quantum yields, and the phosphorescence signal decays are determined. In the neat film a red-shifted phosphorescent excimer emission is observed. In diluted solid solution (polystyrene and dicarbazole-biphenyl films) as well as in de-aerated liquid solutions (tetrahydrofuran, toluene, chloroform) high phosphorescence quantum yields are obtained. In air-saturated liquid solutions, the phosphorescence efficiency is reduced by oxygen quenching. At intense short-pulse laser excitation the phosphorescence lifetime is shortened by triplet–triplet annihilation. No amplification of spontaneous emission was observed.

title: Lagrange-Mesh Method for Deformed Nuclei With Relativistic Energy Density Functionals
Creators: name: Typel, Stefan
Publisher: name: Frontiers Media S.A.
Year: 2023

description: The application of relativistic energy density functionals to the description of nuclei leads to the problem of solving self-consistently a coupled set of equations of motion to determine the nucleon wave functions and meson fields. In this work, the Lagrange-mesh method in spherical coordinates is proposed for numerical calculations. The essential field equations are derived from the relativistic energy density functional and the basic principles of the Lagrange-mesh method are delineated for this particular application. The numerical accuracy is studied for the case of a deformed relativistic harmonic oscillator potential with axial symmetry. Then the method is applied to determine the point matter distributions and deformation parameters of self-conjugate even-even nuclei from ⁴He to ⁴⁰Ca.
Convergence Rate Analysis of Distributed Gossip (Linear Parameter) Estimation: Fundamental Limits and Tradeoffs

description: The paper considers gossip distributed estimation of a (static) distributed random field (a.k.a., large scale unknown parameter vector) observed by sparsely interconnected sensors, each of which only observes a small fraction of the field. We consider linear distributed estimators whose structure combines the information \emph{flow} among sensors (the \emph{consensus} term resulting from the local gossiping exchange among sensors when they are able to communicate) and the information \emph{gathering} measured by the sensors (the \emph{sensing} or \emph{innovations} term.) This leads to mixed time scale algorithms--one time scale associated with the consensus and the other with the innovations. The paper establishes a distributed observability condition (global observability plus mean connectedness) under which the distributed estimates are consistent and asymptotically normal. We introduce the distributed notion equivalent to the (centralized) Fisher information rate, which is a bound on the mean square error reduction rate of any distributed estimator; we show that under the appropriate modeling and structural network communication conditions (gossip protocol) the distributed gossip estimator attains this distributed Fisher information rate, asymptotically achieving the performance of the optimal centralized estimator. Finally, we study the behavior of the distributed gossip estimator when the measurements fade (noise variance grows) with time; in particular, we consider the maximum rate at which the noise variance can grow and still the distributed estimator being consistent, by showing that, as long as the centralized estimator is consistent, the distributed estimator remains consistent.

Kulhulmcilh and iixsalh : our land and medicine : creating a Nuxalk database of museum collections
Creators: name: Leischner, Emily Jean
Publisher: name: University of British Columbia
Year: 2018

description: Museum staff have recently embraced digital technologies as an avenue for providing sustainable access to the cultural heritage of First Nations and descendent communities. While museums, universities and partnering institutions are increasingly collaborating on digital initiatives with Indigenous communities, the resulting projects necessarily involve compromise between parties working with often different goals, publics, and epistemologies. Understanding and evaluating the meaning, value, and success of projects that Indigenous peoples control at all levels is essential to improving future collaborative projects involving First Nations material culture, and to prioritizing Indigneous perspectives at all levels of museum work. In this thesis I examine the process of creating a digitized ethnographic database of museum objects, led by the Ancestral Governance Office of the Nuxalk First Nation in Bella Coola, British Columbia. This Nuxalk-directed database shows how vital Nuxalk culture heritage is to their land and sovereignty, and highlights the importance of the process of creating this database over the final digital product. It 1) challenges assumptions around the invisibility of certain value systems within museum collections databases, 2) emphasizes the future wellbeing of the next generation of Nuxalk people as an important motivation for this work, and 3) calls for more support for Indigenous-controlled projects like this one from the government and institutions caring for Indigenous heritage.

description: The photo-induced reduction of flavin mononucleotide (FMN) in aqueous solutions is studied by absorption spectra measurement under aerobic and anaerobic conditions. Samples without exogenous reducing agent and with the exogenous reducing agents ethylene-diamine-tetraacetic acid (EDTA) and dithiothreitol (DTT) are investigated. Under anaerobic conditions the photo-induced reduction with and without reducing agents is irreversible. Under aerobic conditions the photo-reduction without added reducing agent is small compared to the photo-degradation, and the photo-reduction of FMN by the reducing agents is reversible (re-oxidation in the dark). During photo-excitation of FMN the dissolved oxygen is consumed by singlet oxygen formation and subsequent chemical reaction. After light switch-off slow re-oxidation (slow absorption recovery) occurs due to air in-diffusion from surface. EDTA degradation by FMN excitation leads to oxygen scavenging. The quantum efficiencies of photo-reduction under aerobic and anaerobic conditions are determined. The re-oxidation of reduced FMN under aerobic conditions and due to air injection is investigated.

description: Applications of a method recently suggested by one of the authors (R.L.) are presented. This method is based on the use of dimensional recurrence relations and analytic properties of Feynman integrals as functions of the parameter of dimensional regularization, $d$. The method was used to obtain analytical expressions for two missing constants in the $ε$-expansion of the most complicated master integrals contributing to the three-loop massless quark and gluon form factors and thereby present the form factors in a completely analytic form. To illustrate its power we present, at transcendentality weight seven, the next order of the $ε$-expansion of one of the corresponding most complicated master integrals. As a further application, we present three previously unknown terms of the expansion in $ε$ of the three-loop non-planar massless propagator diagram. Only multiple $ζ$ values at integer points are present in our result.

Clonal analysis of human mammary cell transformation and X-ray sensitivity
Creators: name: Balani, Sneha
Publisher: name: University of British Columbia
Year: 2018

description: Intra-tumoural biological, transcriptional and genomic heterogeneity are hallmarks of human breast cancers. However, tumour propagating activity appears confined to subsets of cells within each tumour. This finding is thought to indicate a persistence of mechanisms that maintain a hierarchical growth and differentiation structure in the normal mammary gland. Because little is known about the responses of either primary normal or malignant human mammary cells to existing therapies, this thesis sought to examine the intrinsic sensitivity of different purified human mammary colony-forming cell (CFC) types and tumours derived from them to ionizing radiation. Luminal progenitor (LP) CFCs were found to be ~1.5-fold more radioresistant than basal cell (BC) CFCs and LPs also showed evidence of checkpoint adaptation, slower repair activity and greater predisposition of γH2AX foci accumulation. Two human breast cancer cell lines (MDA-MB231 and SUM149) and a non-tumorigenic human mammary cell line (MCF-10A) were all found to be more radioresistant than the normal LP-CFCs. CFCs isolated from 8-week tumours generated in mice transplanted with normal human BCs or LPs transduced with KRASG¹²D showed even greater radioresistance and this was further increased in serially passaged derivative lines with more aggressive growth properties. To examine the responsiveness of malignant cells with tumor-initiating cell (TIC) activity in vivo, a dose-response analysis was first undertaken of their frequencies in the MDA-MB231 and SUM149 cells. Limiting dilution analysis (LDA) and single-cell transplants showed the frequency of TICs in both to be very high (<10%), but with increasingly marked inhibition of their detection in tumours initiated from innocula containing 2x10⁴ cells or more. Analogous LDA measurements of the TICs in KRASG12D-transduced BCs and LPs, yielded frequencies of ~0.2% and ~0.07%, respectively, in contrast to the frequencies of 0.02-0.5% for BCs and 0.01-0.6% for LPs for tumours initiated from 3x10⁴-10⁶ cells. These results demonstrate the heterogeneity of treatment responses in normal human mammary cells with innate proliferative ability that can be heightened by transformation. They also reveal the complex clonal dynamics operative in the growth of TICs in vivo that may confound interpretation of treatment effects assessed only by measuring immediate changes in tumor size.

title: The crisis of cultural authority in museums : contesting human remains in the collections of Britain
Creators: name: Jenkins, Tiffany
Publisher: name: University of Kent
Year: 2022

description: Museums in Britain have displayed and researched human remains since the eighteenth century. However, in the last two decades human remains in collections have become subject to claims and controversies. Firstly, human remains associated with acquisition during the colonial period have become increasingly difficult to retain and have been transfered to culturally affiliated overseas indigenous groups. Secondly, a group of British Pagans have formed to make claims on ancient human remains in collections. Thirdly, human remains that are not requested by any community group, and of all ages, have become the focus of concerns expressed about their treatment by members of the profession. A discourse arguing for 'respect' has emerged, which argues that all human remains should be treated with new care. The claims made on human remains have been vigourously but differentially contested by members of the sector, who consider the human remains to be unique research objects. This thesis charts the influences at play on the contestation over human remains and examines its construction. The academic literature tends to understand changes to museums as a result of external factors. This thesis argues that this problem is influenced by a crisis of legitimacy and establishes that there are strong internal influences. Through a weak social constructionist approach I demonstrate that the issue has been promoted by influential members of the sector as part of a broader attempt to distance themselves from their foundational role, as a consequence of a crisis of cultural authority stimulated by external and internal factors. The symbolic character of human remains in locating this problem is informed by the unique properties of dead bodies and is influenced by the significance of the body as a scientific object; its association with identity work and as a site of political struggle, in the high modem period.

description: There is no consensus on the taxonomy of Uralic, and different models exist even for the well-studied western branches of the family.
Häkkinen's (2007, 2009) idea that Saami, Finnic and Mordvin form a genealogical node ("West Uralic"), has received surprisingly wide acceptance in recent literature on linguistics as well as prehistory, even though the postulation of West Uralic is based on rather few arguments. In this poster we discuss the alleged phonological innovations and refute their probative value.

description: The pyrene-flavin (isoalloxazine) dyad, PFD {C44H31N5O5; CA Index name: 1-pyrenepropanoic acid, α-[[4,10-dihydro-2,4-dioxo-10-phenylbenzo[g]pteridin-3(2H)-yl)acetyl]amino]-, phenylmethyl ester, (αR)–(9Cl); CA Registry number: 618907-57-6}, dissolved in either dichloromethane or acetonitrile is characterized by absorption and emission spectroscopy. Absorption cross-section spectra, stimulated emission cross-section spectra, fluorescence quantum distributions, quantum yields, and degrees of fluorescence polarisation are determined. The fluorescence decay after femtosecond pulse excitation is determined by fluorescence up-conversion. The ground-state absorption recovery is determined by picosecond pump and probe transmission measurements. The dye photo-stability is investigated by observation of absorption spectral changes due to prolonged blue-light excitation. The absorption spectrum of PFD dyad resembles the superposition of the absorption of isoalloxazine (flavin) and 1-methylpyrene. Long-wavelength photo-excitation of the flavin moiety causes fluorescence quenching by ground-state electron transfer from pyrene to isoalloxazine. Short-wavelength photo-excitation of the pyrene moiety causes (i) excited-state electron transfer from pyrene to isoalloxazine, and (ii) Förster-type energy transfer from pyrene to flavin followed by ground-state electron transfer from pyrene to flavin.

description: This document describes initial plans and roadmaps for the standardisation, innovation and exploitation of the works developed in the SAFE-6G project.

Regarding standardisation, the initial plan proposes to i) identify the most relevant SDOs and other European initiatives working in security and trust, and ii) actively monitor and analyse potential contributions to engage with them. The proposed contributions will take various forms, including monitoring activities, active participation, engaging representatives from SDOs, and proposing new study and work items that may lead to new standards.

Regarding innovation and exploitation, the initial plan and roadmap outlines the strategic phases and milestones designed to foster innovation and maximize the exploitation of project outcomes through robust IPR management. By analysing the specific contributions and limitations of each partner, the SAFE-6G project is well positioned to enhance network performance, security, and scalability, thereby achieving its strategic goals and maximizing the potential for successful exploitation of new technologies.

With this deliverable, partners will have a roadmap and guidelines to ensure the optimal use of the project's results in terms of standardisation, innovation and exploitation.

description: The GALEX Ultraviolet Virgo Cluster Survey (GUViCS) is a complete blind survey of the Virgo cluster covering about 40 sq. deg. in the far UV (FUV, lambda_eff=1539A, Delta-lambda=442A) and about 120 sq. deg. in the near UV (NUV, lambda_eff=2316A, Delta-lambda=1060A). The goal of the survey is to study the ultraviolet (UV) properties of galaxies in a rich cluster environment, spanning a wide luminosity range from giants to dwarfs, and regardless of prior knowledge of their star formation activity. The UV data will be combined with those in other bands (optical: NGVS; far-infrared - submm: HeViCS; HI: ALFALFA) and with our multizone chemo-spectrophotometric models of galaxy evolution to make a complete and exhaustive study of the effects of the environment on the evolution of galaxies in high density regions. We present here the scientific objectives of the survey, describing the observing strategy and briefly discussing different data reduction techniques. Using UV data already in-hand for the central 12 sq. deg. we determine the FUV and NUV luminosity functions of the Virgo cluster core for all cluster members and separately for early- and late-type galaxies and compare it to the one obtained in the field and other nearby clusters (Coma, A1367). This analysis shows that the FUV and NUV luminosity functions of the core of the Virgo clusters are flatter (alpha about -1.1) than those determined in Coma and A1367. We discuss the possible origin of this difference

description: The interplay between magnetism and superconductivity in LaFeAsO_0.945F_0.055 was studied as a function of hydrostatic pressure up to p~2.4GPa by means of muon-spin rotation (\muSR) and magnetization measurements. The application of pressure leads to a substantial decrease of the magnetic ordering temperature T_N and a reduction of the magnetic phase volume and, at the same time, to a strong increase of the superconducting transition temperature T_c and the diamagnetic susceptibility. From the volume sensitive \muSR measurements it can be concluded that the superconducting and the magnetic areas which coexist in the same sample are inclined towards spatial separation and compete for phase volume as a function of pressure.

description: Background Prions as causative agents of transmissible spongiform encephalopathies (TSEs) in humans and animals are composed of the infectious isomer, PrPSc, of the cellular prion protein, PrPC. The conversion and thus the propensity of PrPC to adopt alternative folds leads to the species-specific propagation of the disease. High pressure is a powerful tool to study the physico-chemical properties of proteins as well as the dynamics and structure of folding intermediates. Results Conformational intermediates of the human prion protein huPrPC were characterized by a combination of hydrostatic pressure (up to 200 MPa) with two-dimensional NMR spectroscopy. All pressure effects showed to be reversible and there is virtually no difference in the overall pressure response between the folded core of the N-terminal truncated huPrPC(121–230) and the full-length huPrPC(23–230). The only significant differences in the pressure response of full-length and truncated PrP suggest that E168, H187, T192, E207, E211 and Y226 are involved in a transient interaction with the unfolded N-terminus. High-pressure NMR spectroscopy indicates that the folded core of the human prion protein occurs in two structural states N1and N2 in solution associated with rather small differences in free enthalpies (3.0 kJ/mol). At atmospheric pressure approximately 29% of the protein are already in the pressure favored conformation N2. There is a second process representing two possible folding intermediates I1 and I2 with corresponding average free enthalpies of 10.8 and 18.6 kJ/mol. They could represent preaggregation states of the protein that coexist at ambient pressure with a very small population of approximately 1.2% and less than 0.1%. Further the pressure response of the N-terminus indicates that four different regions are in a fast equilibrium with non-random structural states whose populations are shifted by pressure.

description: We investigate the sensitivity of the time evolution of semiclassical wave packets in two-dimensional chaotic billiards with respect to local perturbations of their boundaries. For this purpose, we address, analytically and numerically, the time decay of the Loschmidt echo (LE). We find the LE to decay exponentially in time, with the rate equal to the classical escape rate from an open billiard obtained from the original one by removing the perturbation-affected region of its boundary. Finally, we propose a principal scheme for the experimental observation of the LE decay.

description: We calculate the electronic spectrum of bilayer graphene in perpendicular magnetic fields non-perturbatively. To accomodate arbitrary displacements between the two layers, we apply a periodic gauge based on singular flux vortices of phase $2\\pi$. The resulting Hofstadter-like butterfly plots show a reduced symmetry, depending on the relative position of the two layers against each other. The split of the zero-energy relativistic Landau level differs by one order of magnitude between Bernal- and non-Bernal stacking.

description: Lassa fever is a viral haemorrhagic fever caused by an arenavirus. The disease is endemic in West African countries, including Guinea. The rodents Mastomys natalensis and Mastomys erythroleucus have been identified as Lassa virus reservoirs in Guinea. In the absence of a vaccine, rodent control and human behavioural changes are the only options to prevent Lassa fever in highly endemic areas. We performed a 4 year intervention based on chemical rodent control, utilizing anticoagulant rodenticides in 3 villages and evaluating the rodent abundance before and after treatment. Three additional villages were investigated as controls. Analyses to assess the effectiveness of the intervention, bait consumption and rodent dynamics were performed. Anthropological investigations accompanied the intervention to integrate local understandings of human–rodent cohabitation and rodent control intervention. Patterns of bait consumption showed a peak at days 5–7 and no consumption at days 28–30. There was no difference between Bromadiolone and Difenacoum bait consumption. The main rodent species found in the houses was M. natalensis. The abundance of M. natalensis, as measured by the trapping success, varied between 3.6 and 16.7% before treatment and decreased significantly to 1–2% after treatment. Individuals in treated villages welcomed the intervention and trapping because mice are generally regarded as a nuisance. Immediate benefits from controlling rodents included protection of food and belongings. Before the intervention, local awareness of Lassa fever was non-existent. Despite their appreciation for the intervention, local individuals noted its limits and the need for complementary actions. Our results demonstrate that chemical treatment provides an effective tool to control local rodent populations and can serve as part of an effective, holistic approach combining rodent trapping, use of local rodenticides, environmental hygiene, house repairs and rodent-proof storage. These actions should be developed in collaboration with local stakeholders and communities.

description: We analyze infrared divergences arising in calculations involving light and massless fields in de Sitter space. We show that these arise from an incorrect treatment of the constant mode of the field, and show that a correct quantization leads to a well-defined and calculable perturbation expansion. We illustrate this by computing the first nontrivial loop correction in a theory of a massless scalar field with a quartic interaction.

title: Promotion of in vivo 5-aminolevulinic acid-photodynamic therapy efficacy by MEK inhibition
Creators: name: Som, Jayoti
Publisher: name: Memorial University of Newfoundland

description: Protoporphyrin IX (PpIX), a heme precursor, is a photosensitizer that is selectively accumulated in cancer cells when pretreated with its precursor, 5-aminolevulinic acid (5-ALA). Exposure of PpIX accumulating-cancer cells to red light induces the generation of reactive oxygen species (ROS) and subsequent stimulation of cancer cell death, which is known as 5-ALA-photodynamic therapy (5-ALA-PDT). Previously, Dr. Hirasawa's lab discovered that inhibiting the oncogenic Ras/MEK pathway increases PpIX accumulation in cancer cells by suppressing PpIX efflux and PpIX conversion to heme. Here, we sought to determine whether the increase of PpIX accumulation by MEK inhibition promotes 5-ALA-PDT efficacy. First, we classified seven human cancer cell lines into three groups – sensitive, moderately sensitive, and least sensitive –based on their sensitivities to 5-ALA-PDT. Pretreating the moderately sensitive and least sensitive cell lines with a MEK inhibitor increased their sensitivities to 5-ALA-PDT, suggesting that MEK activity influences PDT sensitivity of cancer cells. MEK inhibition promoted 5-ALA-PDT induced generation of ROS and the subsequent programmed cell death. Furthermore, combined 5-ALA-PDT with a MEK inhibitor was significantly effective in inhibiting the growth of tumors in nude mice implanted with human colon cancer cells (DLD-1) and increased their overall survival. As the efficacy and safety of MEK inhibitors are clinically established, combined 5-ALA-PDT with MEK inhibition could directly impact 5-ALA-PDT applications in the clinic.

description: We present the first Herschel PACS and SPIRE images of the low-metallicity galaxy NGC6822 observed from 70 to 500 mu and clearly resolve the HII regions with PACS and SPIRE. We find that the ratio 250/500 is dependent on the 24 mu surface brightness in NGC6822, which would locally link the heating processes of the coldest phases of dust in the ISM to the star formation activity. We model the SEDs of some regions HII regions and less active regions across the galaxy and find that the SEDs of HII regions show warmer ranges of dust temperatures. We derive very high dust masses when graphite is used in our model to describe carbon dust. Using amorphous carbon, instead, requires less dust mass to account for submm emission due to its lower emissivity properties. This indicates that SED models including Herschel constraints may require different dust properties than commonly used.

description: This paper describes the developments, role and contributions of the NMR spectroscopy groups in the Structural Proteomics In Europe (SPINE) consortium. Focusing on the development of high-throughput (HTP) pipelines for NMR structure determinations of proteins, all aspects from sample preparation, data acquisition, data processing, data analysis to structure determination have been improved with respect to sensitivity, automation, speed, robustness and validation. Specific highlights are protonless13C-direct detection methods and inferential structure determinations (ISD). In addition to technological improvements, these methods have been applied to deliver over 60 NMR structures of proteins, among which are five that failed to crystallize. The inclusion of NMR spectroscopy in structural proteomics pipelines improves the success rate for protein structure determinations.
Comparative analysis of tunneling magnetoresistance in low-$T_c$ Nb/AlAlOx/Nb and high-$T_c$ Bi$_{2-y}$Pb$_y$Sr$_2$CaCu$_2$O$_{8+δ}$ intrinsic Josephson junctions

description: We perform a detailed comparison of magnetotunneling in conventional low-$T_c$ Nb/AlAlOx/Nb junctions with that in slightly overdoped Bi$_{2-y}$Pb$_y$Sr$_2$CaCu$_2$O$_{8+δ}$ [Bi(Pb)-2212] intrinsic Josephson junctions and with microscopic calculations. It is found that both types of junctions behave in a qualitatively similar way. Both magnetic field and temperature suppress superconductivity in the state-conserving manner. This leads to the characteristic sign-change of tunneling magnetoresistance from the negative at the sub-gap to the positive at the sum-gap bias. We derived theoretically and verified experimentally scaling laws of magnetotunneling characteristics and employ them for accurate extraction of the upper critical field $H_{c2}$. For Nb an extended region of surface superconductivity at $H_{c2}T_c/2$, but remains negative, although very small, above $T_c$. This may indicate existence of an extended fluctuation region, which, however, does not destroy the general second-order type of the phase transition at $T_c$.

description: Motivated by potential realizations in cold-atom or cold-molecule systems, we have performed quantum Monte Carlo simulations of two-component gases of fermions in two dimensions with hard-core interactions. We have determined the gross features of the zero-temperature phase diagram, by investigating the relative stabilities of paramagnetic and ferromagnetic fluids and crystals. We have also examined the effect of including a pairwise, long-range r^(-3) potential between the particles. Our most important conclusion is that there is no region of stability for a ferromagnetic fluid phase, even if the long-range interaction is present. We also present results for the pair-correlation function, static structure factor, and momentum density of two-dimensional hard-core fluids.

description: With the recent change in public policy, the purpose of this multi-case study is to better understand the implications of cannabis legalization for festivals, including how changes in legislation are affecting policy development and implementation related to cannabis use by attendees, volunteers, and staff. By exploring the approach taken by multiple festival organizations, the diverse issues that need to be considered by organizers are highlighted. While the cases are festivals, the considerations are relevant to diverse tourism attraction that must consider how legal changes affect their policies and operations.

description: The 6G vision for an open, distributed and user-centric evolution of the current Service Based Architecture (SBA) core network creates many security challenges and risks. In the envisioned 6G ecosystem, trusted connections are critical for all parties involved, extending security and privacy to a more inclusive framework, such as trustworthiness, which should be assured as a native feature. The most significant paradigm adjustments in the envisioned user-centric 6G system are the shift from a security-only focus to a broader scope of native trustworthiness, clarifying that the term "trustworthiness" refers to a holistic approach, including safety, security, privacy, resilience andreliability.

SAFE-6G aims at implementing such a trustworthy framework to support and enhance the trust over the next evolution of the 5G network and the managed resources.This document introduces a reference architectural blueprint to instantiate this new trustworthy 6G ecosystem. The impact of this new paradigm is also analysed from the point of view of the different stakeholders and actors linked to 5G/6G networks and the new roles, consents and opportunities it implies for them.

Based on the architectural blueprint, different domains have been defined grouping together building blocks and components that have been identified. For each domain, an extended set of functional and non-functional requirements has been proposed towards realising this blueprint to a detailed architecture in D2.2 that will drive the proof-of-concept implementation and validation of the SAFE-6G ecosystem in WP5. These requirements create a highly ambitious view of the envisioned 6G framework and provide strong guarantees, to related stakeholders, about the impact and ambition that can be achieved by the project.

In the last part, ambitious Use Case scenarios are presented along with some initial specific requirements.

This document is the first deliverable of WP2- Realisation Process, Requirements and Reference Architecture Design and will be completed in the next months by two other deliverables: D2.2- Overall SAFE-6G Framework and Reference Architecture Design (due in M10/October 2024) and D2.3- Metaverse use-cases definition with virtual-assistant for user-centric configuration (due in M12/December 2024).

subject: Cayuga Collection

description: By introducing Cayuga Collection as one of the world leaders in sustainable travel, my case study explores principles for building organizational resilience. I will illustrate effective and innovative solutions regarding crisis management strategies through the lens of the Panarchy Adaptive Cycle Model. To explore the potential of companies with a high level of resilience and flexible business operations to recover faster from crisis, I am going to outline management actions all while discussing their potential to constitute competitive advantages. Through interviews, my own insights into Cayuga’s company culture, and personal communication over a period of six months, I will describe how tourism companies’ continuous commitment to their sustainability strategy can set them apart from their competitors. Further, I will situate my findings within a broader industry context. Based on my research, I argue that companies such as Cayuga that conduct business operations all while considering the triple bottom line, imply principles for building resilience, and embrace flexible but effective crisis management are the ones that navigate the transition of an entire industry towards sustainable consumption.
