description: We explore the impact of commensurate multifrequency driving protocols on the stability of topological edge modes in topological 1D systems of spinless fermions. Using Floquet theory, we show that all the topological phase transitions can be mapped to their single-frequency counterparts in terms of effective driving parameters. This drastic simplification can be explained by considering the gap closures in the quasienergy dispersion. These gap closures are pinned to high-symmetry points, where all the effective Floquet Hamiltonians collapse to the same form. While for all protocols all topological phase transitions coincide, the gap size and the number of edge modes in the quasienergy spectra vary considerably depending on the chosen driving pattern. This gives rise to a full range of edge states with different degrees of localization, from highly localized to completely delocalized. Switching between different driving protocols then suggests a dynamical control of the localization and stability of topological edge modes, with possible applications in quantum computation. We illustrate our findings on three paradigmatic fermionic systems -- namely the Kitaev chain, the Su-Schrieffer-Heeger model, and the Creutz ladder, and demonstrate how to control the localization length of the corresponding edge states.

The Nature, Evolution, Clustering and X-ray Properties of Extremely Red Galaxies in the CDFS/GOODS field

description: We identify a deep sample of 198 extremely red objects (EROs) in (50.4 sq. arcmin of) the Chandra Deep Field South, selected as I-K>3.92 galaxies to a limit K=22. The ERO number counts remain well below the predictions for pure luminosity evolution, and fall below even a non-evolving model, suggesting the comoving number density of passive/very red galaxies decreases with redshift. The angular correlation function of these EROs indicates stronger clustering than that of other galaxies at the same magnitudes, and is best-fitted by models in which the EROs have a comoving correlation radius 12.5/h Mpc, or 21.4/h Mpc in a stable clustering model. We find a 40-arcsec diameter grouping of 10 EROs, centered on the Chandra source (and ERO) XID:58, with colours suggesting a cluster of mostly passive EROs at approx. z=1.5. The 942 ksec Chandra survey detected 73 X-ray sources in the area of our ERO sample, of which 17 coincide with EROs. Of these sources, 13 have X-ray properties indicative of obscured AGN, while the faintest 4 may be starburst galaxies. In addition, we find evidence that Chandra sources and EROs are positively cross-correlated at non-zero (2-20 arcsec) separations, implying that they tend to trace the same large-scale structures.

description: The use of writing for the preservation and transmission of administrative, scientific, literary and sacred knowledge has a long history. From the third millennium BCE on, many forms of social processes – intellectual, religious, political and others – have been increasingly materialized in the form of a variety of document types (tablets, bones, papyri, scrolls, parchments, books). Some of them were collected in archives or libraries that were dependent on royal palaces, governmental institutions and temples but also in private contexts. The publication Collect and Preserve assembles a number of studies devoted to material aspects of collecting texts in ancient Egypt, Mesopotamia, Qumran, Medieval Japan, and Korea under the Chosŏn-Dynasty (1392–1910).

description: In this work, we make use of Lie algebraic methods to obtain the time evolution operator for an optomechanical system with linear and quadratic couplings between the field and the mechanical oscillator. Firstly, we consider the case of a non-driven system and find its exact time evolution operator, secondly we consider the case of a forced system whose time evolution operator is obtained in an approximate form. We confront our analytical results with a numerical simulation and find a good agreement between them.

description: We propose and experimentally demonstrate a scheme which effects hyperfine averaging during a Ramsey interrogation of a clock transition. The method eliminates the need to average over multiple optical transitions, reduces the sensitivity of the clock to its environment, and reduces inhomogeneous broadening in a multi-ion clock. The method is compatible with auto-balanced Ramsey spectroscopy, which facilitates elimination of residual shifts due to imperfect implementation and ac Stark shifts from the optical probe. We demonstrate the scheme using correlation spectroscopy of the $^1S_0$-to-$^3D_1$ clock transition in a three-ion Lu+ clock. From the demonstration we are able to provide a measurement of the $^3D_1$ quadrupole moment, $Θ(^3D_1)=0.634(9)ea_0^2$.

description: Understanding of the nature of dark energy, which appears to drive the expansion of the universe, is one of the central problems of physical cosmology today. In an earlier paper [Daly & Djorgovski (2003)] we proposed a novel method to determine the expansion rate and the deceleration parameter in a largely model-independent way, directly from the data on coordinate distances. Here we expand this methodology to include measurements of the pressure of dark energy, its normalized energy density, and the equation of state parameter as functions of redshift. We then apply this methodology to a new, combined data set of distances to supernovae and radio galaxies.

description: "Code is law" is the funding principle of cryptocurrencies. The security, transferability, availability and other properties of a crypto-asset are determined by the code through which it is created. If code is open source, as it happens for most cryptocurrencies, this principle would prevent manipulations and grant transparency to users and traders. However, this approach considers cryptocurrencies as isolated entities thus neglecting possible connections between them. Here, we show that 4% of developers contribute to the code of more than one cryptocurrency and that the market reflects these cross-asset dependencies. In particular, we reveal that the first coding event linking two cryptocurrencies through a common developer leads to the synchronisation of their returns in the following months. Our results identify a clear link between the collaborative development of cryptocurrencies and their market behaviour. More broadly, our work reveals a so-far overlooked systemic dimension for the transparency of code-based ecosystems and we anticipate it will be of interest to researchers, investors and regulators.

description: In this paper we obtain the space-time generated by a time-like current-carrying superconducting screwed cosmic string(TCSCS). This gravitational field is obtained in a modified scalar-tensor theory in the sense that torsion is taken into account. We show that this solution is comptible with a torsion field generated by the scalar field $ϕ$. The analysis of gravitational effects of a TCSCS shows up that the torsion effects that appear in the physical frame of Jordan-Fierz can be described in a geometric form given by contorsion term plus a symmetric part which contains the scalar gradient. As an important application of this solution, we consider the linear perturbation method developed by Zel'dovich, investigate the accretion of cold dark matter due to the formation of wakes when a TCSCS moves with speed $v$ and discuss the role played by torsion. Our results are compared with those obtained for cosmic strings in the framework of scalar-tensor theories without taking torsion into account.

High-field $\langle 111 \rangle$ spin wave fits show that $\rm Yb_2Ti_2O_7$ is extremely close to an antiferromagnetic phase boundary. Classical Monte Carlo simulations based on the interactions inferrred from high field spin wave measurements confirm $ψ_2$ antiferromagnetism is metastable within the FM ground state.

Contesting the "Common Destiny": Citizenship in Decolonising New Caledonia

description: For forty years, the political landscape of the French territorial community sui generis of New Caledonia has been divided on the question of independence. In 1998, pro and anti-independence leaders signed the Noumea Accord with the French Government agreeing to a referendum on independence in November 2018 and a gradual, irreversible transfer of certain sovereign powers to New Caledonia. One of the most controversial aspects of the agreement concerned the creation of a “citizenship of New Caledonia”, constituting the basis for restrictions to voting rights in local provincial-level elections and the protection of local employment. Moreover, it acts as a social, legal and political mechanism for the construction of the “common destiny” among the New Caledonian population, which, in the event of independence, will transform into a nationality. New Caledonia thus became the first part of France to possess its own distinct citizenship, breaking with the principle of indivisibility at the foundation of the Republic since the French Revolution. Considerable opposition has emerged in response to the exclusion of many thousands of French citizens from New Caledonian citizenship who do not satisfy the minimum residency requirements. However, proponents of citizenship argue that it is a necessary element of the decolonisation process, acting as a counter-measure to immigration, which risks preventing the indigenous Kanak population from being heard at the ballot box concerning New Caledonia’s future. This thesis provides an interpretive analysis of how citizenship is claimed and contested in New Caledonia. It examines how the decolonisation process shapes the distribution of rights and obligations associated with citizenship, exploring in depth how people construct legitimacy within the political community. Such a study enriches our understanding of contemporary processes of decolonisation, especially in overseas territories, where scholars often overlook the politics of citizenship. It is argued that the decolonisation process necessitates a re-conceptualisation of the political community, both in relation to the dynamics of inclusion and exclusion derived from the colonial past and contemporary debates over migration between metropole and territory. In the New Caledonian case, the Kanak independence movement has contested the universal basis of French republicanism, while New Caledonian citizenship invites a serious reflection on the moral legitimacy of non-indigenous populations within the political community. This thesis therefore illuminates the problematic nexus between legally defined political communities and the complex questions of identity and belonging that emerge from colonisation. Regardless of the outcome following the end of the Noumea Accord transitionary period, the matter of citizenship is likely to persist well into the future.

description: The North Atlantic Oscillation (NAO) monthly index is studied from 1825 till 2002 in order to identify the scaling ranges of its fluctuations upon different delay times and to find out whether or not it can be regarded as a Markov process. A Hurst rescaled range analysis and a detrended fluctuation analysis both indicate the existence of weakly persistent long range time correlations for the whole scaling range and time span hereby studied. Such correlations are similar to Brownian fluctuations. The Fokker-Planck equation is derived and Kramers-Moyal coefficients estimated from the data. They are interpreted in terms of a drift and a diffusion coefficient as in fluid mechanics. All partial distribution functions of the NAO monthly index fluctuations have a form close to a Gaussian, for all time lags, in agreement with the findings of the scaling analyses. This indicates the lack of predictive power of the present NAO monthly index. Yet there are some deviations for large (and thus rare) events. Whence suggestions for other measurements are made if some improved predictability of the weather/climate in the North Atlantic is of interest. The subsequent Langevin equation of the NAO signal fluctuations is explicitly written in terms of the diffusion and drift parameters, and a characteristic time scale for these is given in appendix.

description: Adopting the 3+1 neutrino mixing parameters by the IceCube and shortbase line experiments, we investigate the sterile-active neutrino oscillation effects on the supernova neutrino process. For the sterile neutrino ($ν_s$), we study two different luminosity models. First, we presume that the $ν_s$ does not interact with other particles through the standard interactions apart from the oscillation with the active neutrinos. Second, we consider that $ν_s$ can be directly produced by $ν_e$ scattering with matter. In both cases, we find that the pattern of neutrino oscillations can be changed drastically by the $ν_s$ in supernova environments. Especially multiple resonances occur, and consequently affect thermal neutrino-induced reaction rates. As a result, $^7$Li, $^7$Be, $^{11}$B, $^{11}$C, $^{92}$Nb, $^{98}$Tc and $^{138}$La yields in the $ν$-process are changed. Among those nuclei, $^7$Li and $^{11}$B yields can be constrained by the analysis of observed SiC X grains. Based on the meteoritic data, we conclude that the second model can be allowed while first model is excluded. The viability of the second model depends on the sterile neutrino temperature and the neutrino mass hierarchy.

description: In this study, tridentate 2,6-bis(5,6-dimethyl-1H-benzimidazol-2-yl)pyridine ligand (L1) and eight derivatives (L2–9) were prepared by substitution with alkyl chains and Ru(II) complexes of these ligands (C1–9) were synthesized. The synthesized ligands and their Ru(II) complexes were characterized by FTIR, UV–vis, 1H-NMR, and ESI/MS spectroscopic methods. The absorption and the emission spectra of the complexes were examined, HOMO–LUMO energy levels of the complexes were determined by cyclic voltammetry and their use as photosensitizer in dye-sensitized solar cells (DSSCs) was investigated. The effects of alkyl chain substitution on absorption in the visible region and on the current–potential characteristics of the complexes are discussed. The effects of this modification on the important parameters for DSSCs such as absorption, current density were examined and power conversion efficiency values of the Ru(II) complexes are reported.

description: Professional learning communities (PLCs) are becoming increasingly popular, in a recognition that teachers’ knowledge is situated in teachers’ daily experiences and best acquired through ongoing practice and reflection. This study examines the relationship between participation in PLCs and teaching practices and tests specific aspects of a PLC framework for sub-Saharan Africa, which has not been studied before. Data originate from a teacher survey implemented with over 2,300 preschool and primary education teachers in Equatorial Guinea, Ghana, and Nigeria. Our results show a positive significant relationship between higher levels of participation in PLC and constructivist student-centered practices for two out of the three countries under study. Findings also indicate that PLCs’ four core characteristics conceptualized by the literature from high-income countries are associated with higher constructivist student-centered practice across all three countries.

description: Der von Nora Schmidt, Nikolas Pissis und Gyburg Uhlmann herausgegebene Band widmet sich der Frage, wie Wissen zwischen verschiedenen Akteuren ausgetauscht wird: wie es den Besitzer wechselt, wie es einen Ort verlässt und von einer Zeit in eine andere wandert. Der Austausch von Wissen hat mit ökonomischen, technischen, materialen und wissenschaftlichen Prozessen zu tun, lässt sich aber auf keinen von ihnen reduzieren. Die Autorinnen und Autoren des Bandes arbeiten daher mit dem Konzept der Wissensoikonomien: Im Zentrum steht die Vielschichtigkeit der Beziehungsgeflechte und Austauschbeziehungen von Menschen und Materialien, Medien, sozialen Praktiken, Traditionen und Institutionen. Ausgehend von der Beobachtung, dass Transfer von Wissen sich in einer Vielzahl von Modalitäten und Geschwindigkeiten, unter sehr unterschiedlichen Bedingungen und teils über sprachliche, geographische und soziale, religiöse und andere identitätsspezifische Grenzen hinweg ereignet, geht das Konzept der Wissensoikonomien der Frage nach, wann solche Wissensbewegungen selbst systembildenden Charakter erhalten. Damit beschreiben Wissensoikonomien ein Spannungsfeld zwischen Ordnung und Transgression. In sechzehn einzelnen Fachbeiträgen werden komplexe Aushandlungsprozesse von Wissen in unterschiedlichen vormodernen Kulturen vom Alten Ägypten, über die verschiedenen antiken Kulturen des Mittelmeerraums, China und Korea bis in die Frühe Neuzeit aufgezeigt.
The relationship between feminism and socialism in England 1883-1914

description: This thesis seeks to explore the relationship between feminism and socialism in England during the period 1883 to 1914. Through an examination of the ideological inheritance of feminism and socialism from the end of the eighteenth century, the socialist revival in the 1880s, the development of the Independent Labour Party and the formation of women's trade union, suffrage and political groups, two related problematics have been identified as having a significant impact upon that relationship. These problematics are, for feminism, difference and equality, and for socialism, independence and alliance. Three related themes - consciousness, subjectivity and common sense - have been further identified as instrumental in the process by which the feminist and socialist problematics led to the development of a number of different feminisms and socialisms evident in England at this time. It is argued that gendered ideology - the allocation of separate spheres to women and men, and an intrinsic notion of difference based upon that separation - entered and divided feminism and socialism at the moment of their formation. It also framed part of the common sense of both women and men. As such, therefore, the struggle for a feminist and socialist future needed to be waged at this level of common sense. The majority of feminists and socialists were, however, unable to conduct their struggles at this level. Instead, what emerged as dominant was a version of socialism which was morally conservative on issues to do with women and the family. Gendered ideology thus was not transcended. What emerged as the dominant strand within feminism was an ideology of motherhood, which pressed women's claims on the basis of their difference from men. There was nothing guaranteed about either of these developments; rather, they were both the result of a complex process of negotiation against the background of a society in a state of change.

description: The gamma-ray bursts detected by the BATSE instrument may be separated into "short", "intermediate" and "long" subgroups. Previous statistical tests found an anisotropic sky-distribution on large angular scales for the intermediate subgroup, and probably also for the short subgroup. In this article the description and the results of a further statistical test - namely the nearest neighbour analysis - are given. Surprisingly, this test gives an anisotropy for the long subgroup on small angular scales. The discussion of this result suggests that this anisotropy may be real.

description: A distributed denial-of-service (DDoS) attack can flood a victim site with malicious traffic, causing service disruption or even complete failure. Public-access sites like amazon or ebay are particularly vulnerable to such attacks, because they have no way of a priori blocking unauthorized traffic. We present Active Internet Traffic Filtering (AITF), a mechanism that protects public-access sites from highly distributed attacks by causing undesired traffic to be blocked as close as possible to its sources. We identify filters as a scarce resource and show that AITF protects a significant amount of the victim's bandwidth, while requiring from each participating router a number of filters that can be accommodated by today's routers. AITF is incrementally deployable, because it offers a substantial benefit even to the first sites that deploy it.

description: We formulate noncommutative self-dual N=4 supersymmetric Yang-Mills theory in D=2+2 dimensions. As in the corresponding commutative case, this theory can serve as the possible master theory of all the noncommutative supersymmetric integrable models in lower dimensions. As a by-product, noncommutative self-dual N=2 supersymmetric Yang-Mills theory is obtained in D=2+2. We also perform a dimensional reduction of the N=2 theory further into N=(2,2) in D=1+1, as a basis for more general future applications. As a typical example, we show how noncommutative integrable matrix N=(1,0) supersymmetric KdV equations in D=1+1 arise from this theory, via the Yang-Mills gauge groups GL(n, R) or SL(2n, R).

description: Quantification of stylistic differences between musical artists is of academic interest to the music community, and is also useful for other applications such as music information retrieval and recommendation systems. Information about stylistic differences can be obtained by comparing the performances of different artists across common musical pieces. In this article, we develop a statistical methodology for identifying and quantifying systematic stylistic differences among artists that are consistent across audio recordings of a common set of pieces, in terms of several musical features. Our focus is on a comparison of ten different orchestras, based on data from audio recordings of the nine Beethoven symphonies. As generative or fully parametric models of raw audio data can be highly complex, and more complex than necessary for our goal of identifying differences between orchestras, we propose to reduce the data from a set of audio recordings down to pairwise distances between orchestras, based on different musical characteristics of the recordings, such as tempo, dynamics, and timbre. For each of these characteristics, we obtain multiple pairwise distance matrices, one for each movement of each symphony. We develop a hierarchical multidimensional scaling (HMDS) model to identify and quantify systematic differences between orchestras in terms of these three musical characteristics, and interpret the results in the context of known qualitative information about the orchestras. This methodology is able to recover several expected systematic similarities between orchestras, as well as to identify some more novel results. For example, we find that modern recordings exhibit a high degree of similarity to each other, as compared to older recordings.

Hot carrier optoelectronic phenomena in van der Waals heterostructures
Creators: name: Linardy, Eric
Publisher: name: Imperial College London

description: Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) exhibit fascinating optical properties including strong light-matter coupling, prominent excitonic effects, and valley-selective circular dichroism. These properties render TMDs as a potential component for advanced optoelectronics devices. One of the most remarkable phenomena of 2D TMDs is the ultrafast charge transfer of photocarriers across van der Waals (vdW) interfaces, which potentially allows realization of hot carrier optoelectronic devices. Hot photocarrier and exciton dynamics in 2D TMDs depend on intrinsic and extrinsic factors such as many-body effects and interface electronic states. Thus, the prospects for exploiting the photophysical properties of 2D TMDs and their heterostructures for hot carrier optoelectronic devices remain largely unexplored. In this thesis, experimental studies on the photophysics and optoelectronic device properties of 2D TMD-based vdW heterostructures are presented. The first part of this thesis discusses an unconventional electro-optic light upconverter. It is shown that ultrafast interlayer transfer of photoexcited carriers can be electrically induced, allowing upconversion of relatively weak continuous wave laser light. The second part reports on efficient exciton-exciton annihilation (EEA) process in monolayer TMDs. We discover that encapsulation of TMD within hexagonal boron nitride (hBN) films strongly suppresses EEA. The last part reports on unusually robust photocurrent response in a metal-insulator-semiconductor (MIS) heterostructure. It is shown that generation of high energy free carriers via efficient EEA plays a fundamental role in the observed unusual photoresponse of the heterostructures.

description: Background: Clinical research on mobile health (mHealth) interventions is too slow in comparison to the rapid speed of technological advances, thereby impeding sustainable research and evidence-based implementation of mHealth interventions. Objective: We aimed to establish practical lessons from the experience of our working group, which might accelerate the development of future mHealth interventions and their evaluation by randomized controlled trials (RCTs). Methods: This paper is based on group and expert discussions, and focuses on the researchers’ perspectives after four RCTson mHealth interventions for chronic pain. Results: The following five lessons are presented, which are based on practical application, increase of speed, and sustainability: (1) explore stakeholder opinions, (2) develop the mHealth app and trial simultaneously, (3) minimize complexity, (4) manage necessary resources, and (5) apply behavior change techniques. Conclusions: The five lessons developed may lead toward an agile research environment. Agility might be the key factor in the development and research process of a potentially sustainable and evidence-based mHealth intervention.

Un articolo pubblicato su The Journal of Infectious Diseases confronta due studi – uno sperimentale, l’altro teorico – circa l’efficacia della radiazione solare, in particolare degli Uv-B, nell’inattivare il virus Sars-Cov-2. Dal confronto emerge la necessità di considerare un ulteriore contributo – verosimilmente quello dei raggi Uv-A – e nuovi meccanismi indiretti di interazione fra la luce e il virus stesso che coinvolgano il mezzo di diffusione

description: Dust and starlight are modeled for the KINGFISH project galaxies. With data from 3.6 micron to 500 micron, models are strongly constrained. For each pixel in each galaxy we estimate (1) dust surface density; (2) q_PAH, the dust mass fraction in PAHs; (3) distribution of starlight intensities heating the dust; (4) luminosity emitted by the dust; and (5) dust luminosity from regions with high starlight intensity. The models successfully reproduce both global and resolved spectral energy distributions. We provide well-resolved maps for the dust properties. As in previous studies, we find q_PAH to be an increasing function of metallicity, above a threshold Z/Z_sol approx 0.15. Dust masses are obtained by summing the dust mass over the map pixels; these "resolved" dust masses are consistent with the masses inferred from model fits to the global photometry. The global dust-to-gas ratios obtained from this study correlate with galaxy metallicities. Systems with Z/Z_sol > 0.5 have most of their refractory elements locked up in dust, whereas when Z/Z_sol < 0.3 most of these elements tend to remain in the gas phase. Within galaxies, we find that q_PAH is suppressed in regions with unusually warm dust with nu L_nu(70 um) > 0.4L_dust. With knowledge of one long-wavelength flux density ratio (e.g., f_{160}/f_{500}), the minimum starlight intensity heating the dust (U_min) can be estimated to within ~50%. For the adopted dust model, dust masses can be estimated to within ~0.07 dex accuracy using the 500 micron luminosity nu L_nu(500) alone. There are additional systematic errors arising from the choice of dust model, but these are hard to estimate. These calibrated prescriptions may be useful for studies of high-redshift galaxies.

description: ‘Living with Machines: Human stories from the industrial age’ was a free exhibition at Leeds City Museum from July 2022-January 2023. It explored how machines and mechanisation changed life and work in Leeds and the surrounding regions. A collaboration between the British Library and Leeds City Museum, the exhibition was co-curated by Mia Ridge and John McGoldrick. Inspired by the Living with Machines research project, the exhibition unearths new human stories behind material from Leeds Museums & Galleries, brought together with items on loan from the British Library, National Football Museum, National Railway Museum and more. From machines to mass-produced clothing, grassroots women’s football to art, the exhibition paints a relatable picture of how rapid advances in technology changed life and work for everyone. This document contains interpretation for the Living with Machines exhibition, a collaboration between the British Library and Leeds Museums and Galleries that built on the Living with Machines research project. This text was written by exhibition co-curators Mia Ridge and John McGoldrick in a commentable Google Doc so that the Exhibition content and steering groups drawn from across the organisations could review and comment on work in progress. As a working document with all the label text, it contains references to format and design notes for wall panels, etc, including information about which thematic section or captions content is linked to.
