description: This presentation was delivered at UKSG 2025, 31 March - 2 April 2025. 

Abstract: Those involved in running community-led infrastructures and funding models that support Diamond open access will be familiar with questions being repeatedly raised about the sustainability of their work. In this breakout session, we will hear short talks from five initiatives that are engaging directly with this question, in relation to both open access books and journals, even as they sometimes push back against its often unspokenassumptions. Each contributor will unpack what “achieving sustainability” means for them, including reporting on their concrete progress in support of this work, in their own terms, as well as potentially highlighting the limits of understanding sustainability as merely financial. Panellists will also reflect on developments in thebroader scholarly system that potentially both are a challenge for their work and present opportunities. This will be followed by questions from the audience.

description: Radiative feedback from massive stars is a key process to understand how HII regions may enhance or inhibit star formation in pillars and globules at the interface with molecular clouds. We aim to contribute to model the interactions between ionization and gas clouds to better understand the processes at work. We study in detail the impact of modulations on the cloud-HII region interface and density modulations inside the cloud. We run three-dimensional hydrodynamical simulations based on Euler equations coupled with gravity using the HERACLES code. We implement a method to solve ionization/recombination equations and we take into account typical heating and cooling processes at work in the interstellar medium and due to ionization/recombination physics. UV radiation creates a dense shell compressed between an ionization front and a shock ahead. Interface modulations produce a curved shock that collapses on itself leading to stable growing pillar-like structures. The narrower the initial interface modulation, the longer the resulting pillar. We interpret pillars resulting from density modulations in terms of the ability of these density modula- tions to curve the shock ahead the ionization front. The shock curvature is a key process to understand the formation of structures at the edge of HII regions. Interface and density modulations at the edge of the cloud have a direct impact on the morphology of the dense shell during its formation. Deeper in the cloud, structures have less influence due to the high densities reached by the shell during its expansion.

description: Rivers and reservoirs around the world are becoming dumping sites for liquid and solid wastes which are toxic to the fish. The physicochemical parameters and ecotoxicological potential of fish species in Ilorin's major rivers and reservoirs were investigated. Water and fish samples were collected from five sites: Unilorin Reservoir (A), Apodu Reservoir (B), Asa Reservoir (C), Asa River (Harmony) (D), and Asa River (Unity) (E). Excluding rivers (D and E) with low dissolved oxygen (DO) and a slight increase in lead (Pb), all physicochemical parameters were within the NSDWQ and WHO criteria for drinking water. Fish samples at D and E showed changes in the serum biochemical and haematological profiles and induction of micronuclei (MN), nuclear abnormalities (NA) and DNA single-strand break. Antioxidant enzymes were also increased in the fish. Our findings show that water from D and E can cause cytogenotoxic in fish due to hypoxic conditions triggered by Pb. This study will provide valuable health risks and future river water treatment strategies.
Interpolation inequalities in pattern formation

Publisher: name: Dipartimento di Matematica, Università di Bologna

description: In this seminar I will present some interpolation inequalities that involves the BV-norm and some negative norms of a function u. These inequalities are the strong version of some already known estimates in weak form, which play a crucial role in the study of pattern formation. The main ingredient in the proof of these estimates is given by a geometric construction, that was first used by Choksi, Conti, Kohn and Otto in the context of branched patterns in superconductors, and which main idea goes back to De Giorgi. This is a joint work with Felix Otto.

description: We construct a series of model galaxies in rotational equilibrium consisting of gas, stars, and a fixed dark matter (DM) halo and study how these equilibrium systems depend on the mass and form of the DM halo, gas temperature, non-thermal and rotation support against gravity, and also on the redshift of galaxy formation. For every model galaxy we find the minimum gas mass M_g^min required to achieve a state in which star formation (SF) is allowed according to contemporary SF criteria. The obtained M_g^min--M_DM relations are compared against the baryon-to-DM mass relation M_b--M_DM inferred from the \LambdaCDM theory and WMAP4 data. Our aim is to construct realistic initial models of dwarf galaxies (DGs), which take into account the gas self-gravity and can be used as a basis to study the dynamical and chemical evolution of DGs. Rotating equilibria are found by solving numerically the steady-state momentum equation for the gas component in the combined gravitational potential of gas, stars, and DM halo using a forward substitution procedure. We find that for a given M_DM the value of M_g^min depends crucially on the gas temperature T_g, gas spin parameter α, degree of non-thermal support σ_eff, and somewhat on the redshift for galaxy formation z_gf. Depending on the actual values of T_g, α, σ_eff, and z_gf, model galaxies may have M_g^min that are either greater or smaller than M_b. Galaxies with M_DM \ga 10^9 M_sun are usually characterized by M_g^min \la M_b, implying that SF in such objects is a natural outcome as the required gas mass is consistent with what is available according to the \LambdaCDM theory. On the other hand, models with M_DM \la 10^9 M_sun are often characterized by M_g^min >> M_b, implying that they need much more gas than available to achieve a state in which SF is allowed. Abridged.

description: Methicillin-resistant Staphylococcus aureus (MRSA) is among the top threats to global public health and biofilm production is one of the factors attributed to its pathogenesis. This study aims to investigate the biofilm forming ability of 89 clinical MRSA isolated from various sources in Malaysia and to investigate the presence of biofilm-associated and regulatory genes among these isolates. A total of 89.9% (80/89) isolates produced slime layer via Congo red assay while 57.3% (51/89) isolates produced strong biofilm via crystal violet assay. PCR assay revealed 97.8% (87/89) isolates carried at least one of the MSCRAMM with icaBC genes detected at the highest rate (92.1%, 82/89) and highest frequency of agr-I (68.5%, 61/89). Clinical isolates isolated from pus were significantly associated with strong biofilm (p = 0.0449). The obtained results revealed the varying ability of clinical MRSA isolates to form biofilms and highlighted the genetic background associated with biofilms from different sources and clinical presentations.

description: We study the electromagnetic transmission $T$ through one-dimensional (1D) photonic heterostructures whose random layer thicknesses follow a long-tailed distribution --Lévy-type distribution. Based on recent predictions made for 1D coherent transport with Lévy-type disorder, we show numerically that for a system of length $L$ (i) the average $ \propto L^α$ for $0 \propto L$ for $1\leα<2$, $α$ being the exponent of the power-law decay of the layer-thickness probability distribution; and (ii) the transmission distribution $P(T)$ is independent of the angle of incidence and frequency of the electromagnetic wave, but it is fully determined by the values of $α$ and $$.

description: Global supersymmetries of the S-matrices of N = 2, 4, 8 supersymmetric Yang-Mills theories in three spacetime dimensions (without matter hypermultiplets) are shown to be SU(1|1), SU(2|2) and SU(2|2) X SU(2|2) respectively. These symmetries are not manifest in the off-shell Lagrangian formulations of these theories. A direct map between these symmetries and their representations in terms of the Yang-Mills degrees of freedom and the corresponding quantities in Chern-Simons-Matter theories with N >= 4 supersymmetry is also obtained. Dimensional reduction of the on-shell observables of the Yang-Mills theories to two spacetime dimensions is also discussed.

description: Hybrid micellar liquid chromatography was used for practical determination of acid dissociation constant (pKa) of three analytes, namely, ibuprofen (IBU), naproxen (NPX) and benzoic acid (BZA). The proposed method was established based on the principle adopting the dependence of the retention time of ionizable analytes on the mobile phase pH. Simple data manipulation was carried out without the need of specialized software, allowing estimation of practically determined pKa values, which were found to be in accordance with calculated and experimentally determined values, emphasizing on the versatility and applicability of the proposed method. The present methodology carries unique features which support its utility over traditional techniques adopted for pKa determination, like its solubilizing ability, overcoming long retention times experienced in reversed phase chromatography, non-limitation to a specified chemical class and possible justification of the determined pKa values using linear regression equations.

description: We compute the total top-quark pair production cross section at the Tevatron and LHC based on approximate NNLO results, and on the summation of threshold logarithms and Coulomb enhancements to all orders with next-to-next-to-leading logarithmic (NNLL) accuracy, including bound-state effects. We find σ_{t\bar t} = 7.22^{+0.31+0.71}_{-0.47-0.55} pb at Tevatron and σ_{t\bar t} = 162.6^{+7.4+15.4}_{-7.6-14.7} pb at LHC with 7 TeV c.o.m. energy, for m_t=173.3 GeV. The implementation of joint soft and Coulomb resummation, its ambiguities, and the present theoretical uncertainty are discussed in detail. We further obtain new approximate results at N3LO.

description: The 1937 theoretical discovery of Majorana fermions--whose defining property is that they are their own anti-particles--has since impacted diverse problems ranging from neutrino physics and dark matter searches to the fractional quantum Hall effect and superconductivity. Despite this long history the unambiguous observation of Majorana fermions nevertheless remains an outstanding goal. This review article highlights recent advances in the condensed matter search for Majorana that have led many in the field to believe that this quest may soon bear fruit. We begin by introducing in some detail exotic `topological' one- and two-dimensional superconductors that support Majorana fermions at their boundaries and at vortices. We then turn to one of the key insights that arose during the past few years; namely, that it is possible to `engineer' such exotic superconductors in the laboratory by forming appropriate heterostructures with ordinary s-wave superconductors. Numerous proposals of this type are discussed, based on diverse materials such as topological insulators, conventional semiconductors, ferromagnetic metals, and many others. The all-important question of how one experimentally detects Majorana fermions in these setups is then addressed. We focus on three classes of measurements that provide smoking-gun Majorana signatures: tunneling, Josephson effects, and interferometry. Finally, we discuss the most remarkable properties of condensed matter Majorana fermions--the non-Abelian exchange statistics that they generate and their associated potential for quantum computation.

description: We study the attractive Hubbard model with mass imbalance to clarify low temperature properties of the fermionic mixtures in the optical lattice. By combining dynamical mean-field theory with the continuous-time quantum Monte Carlo simulation, we discuss the competition between the superfluid and density wave states at half filling. By calculating the energy and the order parameter for each state, we clarify that the coexisting (supersolid) state, where the density wave and superfluid states are degenerate, is realized in the system. We then determine the phase diagram at finite temperatures.

description: The theoretical analysis of the effect of uniaxial stress on the magnetization of the system of noninteracting nanoparticles is done by an example of heterophase particles of maghemite, epitaxially coated with cobalt ferrite. It is shown that stretching leads to a decrease in the coercive force $H_c$, and compression leads to its growth. The residual saturation magnetization $I_{rs}$ of nanoparticles does not change. With increasing of interfacial exchange interaction, coercive force varies nonmonotonically

description: Poor wound healing is considered an obstacle in diabetics, which requires effective therapy. Our goal was to investigate the combined effect of mint and silver nanoparticle hydrogel films as wound-healing agents in diabetic rats. Thirty rats were arranged into five groups. The hydrogel films were prepared through an eco-friendly method, excluding toxic solvents and diluents. Gel 1 and fucidin showed complete wound-healing effect on the 22nd day, while Gel 2 showed a faster effect on the 16th day, all compared to group 1 which healed in 25 days. Diabetic rats in group 2 healed beyond 25 days. Moreover, Gel 1 and Gel 2 decreased the fasting blood glucose. Gel 2 enhances wound healing in diabetic rats via multiple mechanisms of action, possibly due to the ability of mint and silver nanoparticles to sustain their concentration at the wound site with limited toxicity.

description: This research applies spatial Durbin model to analyse traffic flow distributions via various factors in the urban areas and traffic flow data. The results show that the overall built environment within a buffer area has more significant impact on urban traffic flow compared to the nearby location within a few meters. Areas with more young and white dwellers are associated with more traffic flows. With the influence of COVID-19, residents prefer to spend their daily life in their local neighborhood rather than having long distance travel. The initial findings from this research provide evidence of developing 20-minute city via active travel for achieving net-zero carbon target.

description: Thrips, tiny to medium sized insects with fringed wings are economically important due to their pestiferous and predatory behaviour. They have a wide range of feeding habitats i.e. leaf feeders, to flower, spore, and fungus feeders. Here, we comprehensively characterized the gut bacteria of nine thrips species collected from two geographical areas of India. Moreover, an attempt to elucidate the impact of different feeding habits (leaf, flower, and spore) on the gut microbiota was also carried out. Comparative analyses revealed that the gut bacterial structure at the phylum level was almost similar with dominant phyla such as Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes with few exceptions. Further, at genera level, the gut bacteria were significantly different and revealed the presence of the highest abundance of Rosenbergiella, Wolbachia, Curtobacterium Acinetobacter, and Pseudomonas. Moreover, the gut microbiota was involved in pathways such as Biosynthesis of amino acids, vitamin metabolism etc.

description: The concentration level of a certain metal in soil is often the guideline for evaluating its contamination level. In such a process, ecological standards are the guidelines for assessing ecological risks. In the presence of certain conditions, the risk of contamination can expand beyond the concerned area creating a threat that is based on mobility. Such threat cannot be overlooked and needs to be taken into consideration, as such the work below aims to assess the mobility of metallic trace elements M.T.Es (Pb, Cu, Cd, As, Ni, Cr and Zn) in different soils and mine tailing around an abandoned Pb Zeïda mine in Morocco. The sequential extraction followed a standard BCR four-step procedure and revealed that all M.T.Es were largely associated with the exchangeable and reducible fractions, exhibiting higher mobility susceptibility and bioavailability, except for As. This was consistent with the physico-chemical and mineralogical properties of the local geological composition.
VLT Spectropolarimetry of the Type Ia SN2005ke - A step towards understanding subluminous events

description: We performed optical spectropolarimetric observations of the subluminous Type Ia SN2005ke at 3 epochs (days -8, -7, and +76). The explosion properties are derived by comparing the data to explosion and radiation transfer models. The SN shows polarimetric properties that are very similar to the only other subluminous event for which spectropolarimetry is available, i.e. SN1999by. The data present a very marked dominant axis, which is shared by both the continuum and lines such as SiII 6355, suggesting that the relatively large, global asymmetry is common to the photosphere and the line-forming region. The maximum polarization degree observed in the SiII 6355 absorption reaches 0.39+/-0.08%. At variance with what is seen in core-normal Type Ia, SN2005ke displays significant continuum polarization, which grows from the blue to the red and peaks at about 7000 A, reaching ~0.7%. The properties of the polarization and flux spectra can be understood within the framework of a subluminous delayed-detonation (DD), or pulsating DD scenario, or WD mergers. The difference in appearance with respect to core-normal SNe Ia is caused by low photospheric temperatures in combination with layers of unburned C, and more massive layers of the products of explosive C and O burning. The comparatively high level of continuum polarization is explained in terms of a significant global asymmetry (~15%), which is well reproduced by an oblate ellipsoidal geometry. Our results suggest that SN2005ke arose either from a single-degenerate system in which the WD is especially rapidly rotating, close to the break-up velocity, or from a double-degenerate merger. Based on the current polarization data, we cannot distinguish between these two possibilities.

description: We explore the interplay of network structure, topology, and dynamic interactions between nodes using the paradigm of distributed synchronization in a network of coupled oscillators. As the network evolves to a global steady state, interconnected oscillators synchronize in stages, revealing network's underlying community structure. Traditional models of synchronization assume that interactions between nodes are mediated by a conservative process, such as diffusion. However, social and biological processes are often non-conservative. We propose a new model of synchronization in a network of oscillators coupled via non-conservative processes. We study dynamics of synchronization of a synthetic and real-world networks and show that different synchronization models reveal different structures within the same network.

description: An effective scheme within two displaced bosonic operators with equal positive and negative displacements is extended to study qubit-oscillator systems analytically in an unified way. Many previous analytical treatments, such as generalized rotating-wave approximation (GRWA) [Phys. Rev. Lett. 99, 173601 (2007)] and an expansion in the qubit tunneling matrix element in the deep strong coupling regime [Phys. Rev. Lett. 105, 263603 (2010)] can be recovered straightforwardly in the present scheme. Moreover, further improving GRWA and extension to the finite-bias case are implemented easily. The analytical expressions are then derived explicitly and uniquely, which work well in a wide range of the coupling strengthes, detunings, and static bias including the recent experimentally accessible parameters.

description: Tree Preservation Order (TPO) is used to protect specific trees from damage and destruction, which is determined in high subjectivity. This research collected and analyzed TPO data, aerial images, geographic data, and socio-economic data in the Greater London area and developed a multi-input deep learning (DL) framework to classify TPO-protected and non-TPO-protected trees. The synergy use of aerial images and GIS data with the fusion model of ResNet50 and multilayer perceptron network produced the best classification accuracy of 87.32%. The result indicated the robustness of the multi-input DL model to identify the social attributes of trees compared with the single-input DL model

The nonlinear response of such structures can be greatly enhanced, leading to a low threshold 100% switching operation. We further propose one of the possible realizations based on nonlinear photonic crystal circuits, suitable for optimal all-optical switching.

description: A Grande Guerra foi um conflito que se espalhou pelo mundo no período de 1914 a 1918. O conflito envolveu grandes potências que se aliaram em lados opostos: a Tríplice Entente, inicialmente composta por Inglaterra, França e Rússia, depois pela Itália; e os Impérios Centrais, que agrupavam o Império Alemão, a Áustria-Hungria e o Império Otomano. Os Estados Unidos entraram na guerra somente em 1917, ao lado da Entente.
Ideology, human needs and conflict - the role of fundamental human needs and ideologies in conflict and individual radicalization
Creators: name: Müller, Veronika
Publisher: name: Universität Paderborn
Year: 2021

description: Die Doktorarbeit zielt darauf ab, die theoretischen und empirischen Erkenntnisse der Psychologie und der Ökonomie zu integrieren, um die Mikro-Fundamente von Ideologien zu erklären, d.h. was Ideologien sind und wie sie das individuelle Verhalten und die Entscheidungsfindung beeinflussen können, insbesondere im Rahmen von Konflikten. Mit anderen Worten, diese Dissertation entwickelt und integriert (1) theoretische Annahmen, dass Ideologien die Fähigkeit haben, die individuellen menschlichen Bedürfnisse zu bedienen; (2) ein formales rational choice model, um zu beschreiben, dass Individuen Ideologien annehmen, die am besten zu ihren zugrunde liegenden Bedürfnissen und Präferenzen passen; und (3) liefert empirische Beweise dafür, dass fehlende Bedürfnisbefriedigung die Neigung zum ideologischen Extremismus verstärken kann.
description: This doctoral thesis aims to integrate the theoretical and empirical insights of psychology and economics to explain the micro-foundations of ideologies, i.e., what ideologies are and how they can influence individual behavior and decision-making, in particular, within the conflict nexus. In detail, this doctoral thesis elaborates and integrates (1) theoretical assumptions that ideologies have the capacity to reconcile individuals human needs; (2) a formal rational choice model to describe that individuals adopt ideologies that best match their underlying needs and preferences; and (3) provides empirical evidence that depriving individuals from serving their idiosyncratic needs and preferences can enhance the inclination towards ideological extremism.

Uniformization and an Index Theorem for Elliptic Operators Associated with Diffeomorphisms of a Manifold

description: We consider the index problem for a wide class of nonlocal elliptic operators on a smooth closed manifold, namely differential operators with shifts induced by the action of an isometric diffeomorphism. The key to the solution is the method of uniformization: We assign to the nonlocal problem a pseudodifferential operator with the same index, acting in sections of an infinite-dimensional vector bundle on a compact manifold. We then determine the index in terms of topological invariants of the symbol, using the Atiyah-Singer index theorem.

Spectroscopy of the rotating BTZ black hole via adiabatic invariance
Creators: name: Liu, Xian-Ming
name: Zeng, Xiao-Xiong
name: Liu, Wen-Biao
Publisher: name: arXiv
Year: 2012
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: According to Bohr-Sommerfeld quantization rule, an equally spaced horizon area spectrum of a static, spherically symmetric black hole was obtained under an adiabatic invariant action. This method can be extended to the rotating black holes. As an example, we apply this method to the rotating BTZ black hole and obtain the quantized spectrum of the horizon area. It is shown that the area spectrum of the rotating BTZ black hole is equally spaced and irrelevant to the rotating parameter, which is consistent with the Bekenstein conjecture. Specifically, the derivation do not need the quasinormal frequencies and the small angular momentum limit.

Quick Mapping of historical urbanization in France, case study of Scan Histo 1950 using spatial pixel based approach
Creators: name: Rabehi, Walid
name: Lemoy, Rémi
name: Le Texier, Marion
Publisher: name: Zenodo
Year: 2023
Subjects: Pixel based analysis, Remote sensing, Historical maps, Urban areas, France

description: Automatic detection of human settlement and cities forms on historical maps remains a challenging topic regarding the complexity of the maps semiology, but also because of the general conditions of maps (ink degradation, color change…). The aim of this contribution is to establish an urban layer of France based on historical maps of 1950 using pixel-based approach and multitemporal landcover map. This work will use the produced layers to test whether large cities are more or less parsimonious in terms of land use than smaller cities, at different periods.

Feedback from the IR Background in the Early Universe

Publisher: name: arXiv
Year: 2012
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: It is commonly believed that the earliest stages of star-formation in the Universe were self-regulated by global radiation backgrounds - either by the ultraviolet Lyman-Werner (LW) photons emitted by the first stars (directly photodissociating H_2), or by the X-rays produced by accretion onto the black hole (BH) remnants of these stars (heating the gas but catalyzing H_2 formation). Recent studies have suggested that a significant fraction of the first stars may have had low masses (a few M_sun). Such stars do not leave BH remnants and they have softer spectra, with copious infrared (IR) radiation at photon energies around 1eV. Similar to LW and X-ray photons, these photons have a mean-free path comparable to the Hubble distance, building up an early IR background. Here we show that if soft-spectrum stars, with masses of a few M_sun, contributed more than 1% of the UV background (or their mass fraction exceeded 90%), then their IR radiation dominated radiative feedback in the early Universe. The feedback is different from the UV feedback from high-mass stars, and occurs through the photo-detachment of H^- ions, necessary for efficient H_2 formation. Nevertheless, we find that the baryon fraction which must be incorporated into low-mass stars in order to suppress H_2-cooling is only a factor of few higher than for high-mass stars.

Effect of interface alloying and band-alignment on the Auger recombination of heteronanocrystals
Creators: name: Climente, J. I.

Publisher: name: arXiv
Year: 2011
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We report a numerical study of the effect of interface alloying and band-alignment on the Auger recombination processes of core/shell nanocrystals. Numerical calculations are carried out using a two-band Kane Hamiltonian. Smooth interfaces are found to suppress Auger recombination, the strength of the suppression being very sensitive to the core size. The use of type-II structures constitutes an additional source of suppression, especially when the shell confines electrons rather than holes. We show that "magic" sizes leading to negligible Auger recombination [Cragg and Efros, Nano Letters 10 (2010) 313] should be easier to realize experimentally in nanocrystals with extended interface alloying and wide band gap.
