description: The multi-layer multi-configuration time-dependent Hartree method (ML-MCTDH) is a highly efficient scheme for studying the dynamics of high-dimensional quantum systems. Its use is greatly facilitated if the Hamiltonian of the system possesses a particular structure through which the multi-dimensional matrix elements can be computed efficiently. In the field of quantum molecular dynamics, the effective interaction between the atoms is often described by potential energy surfaces (PES), and it is necessary to fit such PES into the desired structure. For high-dimensional systems, the current approaches for this fitting process either lead to fits that are too large to be practical, or their accuracy is difficult to predict and control. This article introduces multi-layer Potfit (MLPF), a novel fitting scheme that results in a PES representation in the hierarchical tensor (HT) format. The scheme is based on the hierarchical singular value decomposition, which can yield a near-optimal fit and give strict bounds for the obtained accuracy. Here, a recursive scheme for using the HT-format PES within ML-MCTDH is derived, and theoretical estimates as well as a computational example show that the use of MLPF can reduce the numerical effort for ML-MCTDH by orders of magnitude, compared to the traditionally used Potfit representation of the PES. Moreover, it is shown that MLPF is especially beneficial for high-accuracy PES representations, and it turns out that MLPF leads to computational savings already for comparatively small systems with just four modes.

title: Studies of DTF and TTFV-based donor-acceptor systems and redox-active polymer thin films
Creators: name: Afzali, Azadeh
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: 1,4-Dithiafulvene (DTF) is a five-member heterocycle that has been frequently used as a redox-active molecular building block in various organic electronic materials. The combination of two DTF groups via an exo-ring C=C bond leads to formation of well-known tetrathiafulvalene (TTF), which has been extensively studied since the first discovery of its metallic conductivity. Previous research has demonstrated that DTF and tetrathiafulvalene vinylogue (TTFV)-based conjugated molecules and polymers show favored intermolecular interactions (e.g., π–π stacking and chargetransfer interactions) with electron-deficient nitroaromatic compounds (NACs), owing to the electron-donating nature of DTF and TTFV groups. Such properties can be utilized in the design of chemical sensors for detection of NACs, which are an important class of pollutants in the environment. To further understand the interplay between NACs and DTF/TTFV-containing π-systems, a group donor–acceptor ensembles containing nitrophenyl-substituted DTF and TTFV moieties have been investigated in this thesis work. Detailed synthetic methods and structure-property relationships will be discussed in the first chapter. In particular, the structural, electronic, and electrochemical redox properties were systematically examined by Xray single crystallographic, UV-Vis absorption, and cyclic voltametric analyses, in conjunction with density functional theory (DFT) modeling. With the fundamental properties characterized and understood, a new type of TTFV-based redox-active polymer was next designed and prepared. In the second part of this project, a strategy of double-layer polymer film will be introduced. With this method, robust and redox-active TTFV polymer thin films could be efficiently generated on the surface of glassy carbon electrodes. These modified electrodes were found to show sensitive responses to various phenolic compounds at low concentrations (10−8 to 10−7M), suggesting promising application in rapid electrochemical sensing of phenol derivatives and related chemicals.

Subjects: Other education not elsewhere classified

description: This resource is a contribution to the University of Manchester Library's annual "Together" Conference on 15 June 2023. In this session we will introduce the concept of embodied learning and the psychologisation of digital learning. This debate will then be opened to participants to discuss how these practices raise questions of approaches to teaching, learning and the student experience in the Library. Questions which could be worked through are: Do our bodies play a part in the ways that we construct knowledge? How can a confrontation with the digital ask us to re-think how and where learning occurs?
 This interactive breakout session hopes to provoke debate around the creation of educational spaces within the Library and work through assumptions and frameworks as to learners and their practices within these spaces.

description: Predicting the chemical stability of yet-to-be-discovered materials is an important aspect of the discovery and development of virtual materials. The conventional approach for computing the enthalpy of formation based on ab initio methods is time consuming and computationally demanding. In this regard, alternative machine learning approaches are proposed to predict the formation energies of different classes of materials with decent accuracy. In this paper, one such machine learning approach, a novel two-step method that predicts the formation energy of ternary compounds, is presented. In the first step, with a classifier, we determine the accuracy of heuristically calculated formation energies in order to increase the size of the training dataset for the second step. The second step is a regression model that predicts the formation energy of the ternary compounds. The first step leads to at least a 100% increase in the size of the dataset with respect to the data available in the Materials Project database. The results from the regression model match those from the existing state-of-the-art prediction models. In addition, we propose a slightly modified version of the Adam optimizer, namely centered Adam, and report the results from testing the centered Adam optimizer.
The Imprint of Warm Dark Matter on the Cosmological 21-cm Signal

description: We investigate the effects of warm dark matter (WDM) on the cosmic 21-cm signal. If dark matter exists as WDM instead of cold dark matter (CDM), its non-negligible velocities can inhibit the formation of low-mass halos that normally form first in CDM models, therefore delaying star-formation. The absence of early sources delays the build-up of UV and X-ray backgrounds that affect the 21-cm radiation signal produced by neutral hydrogen. With use of the 21CMFAST, code, we demonstrate that the pre-reionization 21-cm signal can be changed significantly in WDM models with a free-streaming length equivalent to that of a thermal relic with mass mx of up to ~10-20 keV. In such a WDM cosmology, the 21-cm signal traces the growth of more massive halos, resulting in a delay of the 21-cm absorption signature and followed by accelerated X-ray heating. CDM models where astrophysical sources have a suppressed photon-production efficiency can delay the 21-cm signal as well, although its subsequent evolution is not as rapid as compared to WDM. This motivates using the gradient of the global 21-cm signal to differentiate between some CDM and WDM models. Finally, we show that the degeneracy between the astrophysics and mx can be broken with the 21-cm power spectrum, as WDM models should have a bias-induced excess of power on large scales. This boost in power should be detectable with current interferometers for models with mx < 3 keV, while next generation instruments will easily be able to measure this difference for all relevant WDM models.

description: We prove non-commutative reciprocity laws on an algebraic surface defined over a perfect field. These reciprocity laws claim the splittings of some central extensions of globally constructed groups over some subgroups constructed by points or projective curves on a surface. For a two-dimensional local field with a finite last residue field the constructed local central extension is isomorphic to a central extension which comes from the case of tame ramification of the Abelian two-dimensional local Langlands correspondence suggested by M. Kapranov.

title: Using human iPSC-derived neural progenitor cells to increase integrin expression in the CNS
Creators: name: Forbes, Lindsey H
Publisher: name: University of St Andrews
Year: 2018

description: Repair of the adult mammalian spinal cord is prohibited by several extrinsic and intrinsic factors. As the CNS matures, growth-promoting proteins such as integrins are developmentally downregulated resulting in a reduced capacity for axonal outgrowth. Integrins are heterodimeric receptors involved in cell-cell and cell-matrix interactions. Specifically, within mature corticospinal tract (CST) axons, integrins are not transported into the axonal compartment. One integrin heterodimer, α9β1, is of particular interest for its ability to promote neurite outgrowth when bound to a component of the injury-induced milieu, tenascin-C. This project aimed to increase integrin expression within the CNS using induced pluripotent stem cell-derived human neural progenitor cells (iPSC-hNPCs). Using immunocytochemistry and western blotting, endogenous integrin expression within iPSC-hNPCs was determined. In addition, overexpression of α9 integrin was achieved using transfection and lentiviral transduction. The capacity of wild type (WT) and α9-hNPCs to extend neurites on tenascin-C was assessed using neurite outgrowth assays. Results revealed increasing α9 integrin expression in hNPCs significantly promoted neurite outgrowth when cultured on tenascin-C. Interestingly, increasing the concentration of human tenascin-C, resulted in increasingly longer neurites from WT hNPCs suggesting hNPCs could actively upregulate integrin expression. Subsequently, WT and α9-hNPCs were transplanted into layer V of the neonatal rat sensorimotor cortex, which projects to the CST. WT and α9-hNPCs survived up to 8 weeks post-transplantation and produced projections along white matter tracts, including areas of the CST. Additionally, hNPCs retained α9-eYFP protein expression in vivo over time and was localised within axonal projections. These results highlight the capabilities of iPSC-hNPCs to promote integrin expression within the rodent CNS presenting one potential avenue to target neuronal replacement following spinal injury. Future research should focus on assessing the regenerative capacity of WT and α9-hNPCs within an injury model concentrating on the ability of these cells to adapt within an injured environment.

description: In this study, we examined the relationship between participating in FP and international co-authorship patterns by using a gravity model with proximity dimensions. Our estimates generally confirm the literature about the effect of various proximity types on scientific collaboration. We found that spatial proximity still matters for the cooperation between scientists, considering the progress in communication and transportation. Cognitive proximity appeared as the most influential factor in generating knowledge. Institutional proximity, represented by the similarity of language and being sibling countries, also affects the co-authorship tendencies. Nevertheless, our estimates on the impact of working together in FP projects on co-publication are not as expected. The results show a relationship between co-partnering in FP projects and co-publication behaviours. Yet, the effect is ambiguous and small. These results imply that further research is needed for the effect of international research programs on co-publishing. In addition to different proximity measures, we need meso- (such as regions) and micro-level (such as universities) analyses. Using InCites, which is based on Web of Science (WoS) data, is one of the limitations of our study since WoS coverage favours some research fields and languages. Also, we used aggregated data in this study, while scientific disciplines vary publication and collaboration behaviours. Further research is needed to deal with these limitations.

title: The provisions on offer for gifted learners with Autism Spectrum Disorder (ASD) in Dubai mainstream schools: capturing students and educators perspectives
Creators: name: El Naggar, Alia
Publisher: name: University of Glasgow
Year: 2023

description: Gifted students with Autism Spectrum Disorder (ASD) are an underserved and under-researched population. Insufficient research has been conducted on this exceptional group of learners with an emphasis on the educational provisions that they are offered in mainstream school settings. With a geographical emphasis on the Middle East, this pragmatic, qualitative study explores the educational provisions on offer for gifted learners with ASD in Dubai mainstream schools. Furthermore, students’ lived experiences and recommendations on such school provisions are captured and presented in this research. The research questions of this study are (1) what are the provisions on offer for gifted students with ASD in Dubai mainstream private primary schools? (2) how do gifted learners with ASD perceive the current offered provision in school? (3) what is recommended by gifted learners with ASD in terms of provisions offered in school? Following a qualitative research approach, semi-structured interviews, survey, and document analysis were used to obtain data. Four gifted students with ASD and six educators (including school leaders, subject teachers, and SEN teachers) took part in semi-structured interviews while twenty-one educators from a variety of Dubai schools participated in the survey. Interviews were transcribed and qualitatively analyzed using coding and thematic analysis. Findings from both the survey and interviews demonstrated insufficient and inappropriate educational structures for this group of twice-exceptional learners. Common themes from educators’ interviews and survey included confusion, uncertainty, and inability to serve such students. Themes from student interviews include misidentification, feelings of frustration, and social challenges. Accordingly, recommendations on the enhancement of educational provisions are proposed as per students’ and educators’ responses. Finally, being the first to investigate the educational provisions of gifted learners with ASD in Dubai mainstream schools, it is hoped that this study will act as a first step towards change in the education of such exceptional learners in the country.

description: We prove that given a Grothendieck category G with a tilting object of finite projective dimension, the induced triangle equivalence sends an injective cogenerator of G to a big cotilting module. Moreover, every big cotilting module can be constructed like that in an essentially unique way. We also prove that the triangle equivalence is at the base of an equivalence of derivators, which in turn is induced by a Quillen equivalence with respect to suitable abelian model structures on the corresponding categories of complexes.

Nuclear Level Densities at High Excitation Energies and for Large Particle Numbers

description: Starting from an independent-particle model with a finite and arbitrary set of single-particle energies, we develop an analytical approximation to the many-body level density $ρ_A(E)$ and to particle-hole densities. We use exact expressions for the low-order moments and cumulants to derive approximate expressions for the coefficients of an expansion of these densities in terms of orthogonal polynomials. The approach is asymptotically (mass number $A \gg 1$) convergent and, for large $A$, covers about 20 orders of magnitude near the maximum of $ρ_A(E)$ (i.e., about half the spectrum). Densities of accessible states are calculated using the Fermi-gas model.

Submm Recombination Lines in Dust-Obscured Starbursts and AGN

description: We examine the use of submm recombination lines of H, He and He$^+$ to probe the extreme ultraviolet (EUV) luminosity of starbursts (SB) and AGN. We find that the submm recombination lines of H, He and He$^+$ are in fact extremely reliable and quantitative probes of the EUV continuum at 13.6 eV to above 54.6 eV. At submm wavelengths, the recombination lines originate from low energy levels (n = 20 -- 50). The maser amplification, which poses significant problems for quantitative interpretation of the higher n, radio frequency recombination lines, is insignificant. Lastly, at submm wavelengths the dust extinction is minimal. The submm line luminosities are therefore directly proportional to the emission measures ($EM_{ION} = n_e \times n_{ion} \times \rm{volume}$) of their ionized regions. We also find that the expected line fluxes are detectable with ALMA and can be imaged at $\sim0.1$\arcsec ~resolution in low redshift ULIRGs. Imaging of the HI lines will provide accurate spatial and kinematic mapping of the star formation distribution in low-z IR-luminous galaxies. And the relative fluxes of the HI and HeII recombination lines will strongly constrain the relative contributions of starbursts and AGN to the luminosity. The HI lines should also provide an avenue to constraining the submm dust extinction curve.

The effect of parenthood on doctoral student's academic socialization and research productivity
Creators: name: Lindahl, Jonas
Publisher: name: Zenodo
Year: 2022

description: This paper reports two studies based on a sample of 868 doctoral students in Sweden that started 2016, 2017, or 2018. The purpose of the studies is to provide insights into how parenthood affects doctoral students’ academic socialisation and research productivity. The results indicate (1) that doctoral student parents co-author less with their supervisors, attend fewer conferences (i.e., academic socialization), and have lower research productivity, than non-parents; (2) that the negative effect of parenthood on academic socialization and research productivity is similar for men and women and also similar over research areas (i.e., Medical and Health sciences, Natural sciences, and Engineering and Technology); and (3) that differences in productivity between parent and non-parent doctoral students are related to co-authoring and attending conferences with their supervisors.

description: In this paper we study the most general covariant action of gravity up to terms that are quadratic in curvature. In particular this includes non-local, infinite derivative theories of gravity which are ghost-free and exhibit asymptotic freedom in the ultraviolet. We provide a detailed algorithm for deriving the equations of motion for such actions containing an arbitrary number of the covariant D'Alembertian operators, and this is our main result. We also perform a number of tests on the field equations we derive, including checking the Bianchi identities and the weak-field limit. Lastly, we consider the special subclass of ghost and asymptotically free theories of gravity by way of an example.

description: In March 2013, a flaring episode from the Crab Nebula lasting ~2 weeks was detected by the Fermi-LAT (Large Area Telescope on board the Fermi Gamma-ray Space Telescope). VERITAS provides simultaneous observations throughout this period. During the flare, the Fermi-LAT detected a 20-fold increase in flux above the average synchrotron flux >100 MeV seen from the Crab Nebula. Simultaneous measurements with VERITAS are consistent with the non-variable long-term average Crab Nebula flux at TeV energies. Assuming a linear correlation between the very-high-energy flux change >1 TeV and the flux change seen in the Fermi-LAT band >100 MeV during the period of simultaneous observations, the linear correlation factor can be constrained to be at most 8.6 * 10^-3 with 95% confidence.

Central galaxies in different environments: Do they have similar properties?

description: We perform an exhaustive comparison among central galaxies from SDSS catalogs in different local environments at 0.01<=z<=0.08. The central galaxies are separated into two categories: group centrals (host halos containing satellites) and field centrals (host halos without satellites). From the latter, we select other two subsamples: isolated centrals and bright field centrals, both with the same magnitude limit. The stellar mass (Ms) distributions of the field and group central galaxies are different, which explains why in general the field central galaxies are mainly located in the blue cloud/star forming regions, whereas the group central galaxies are strongly biased to the red sequence/passive regions. The isolated centrals occupy the same regions as the bright field centrals since both populations have similar Ms distributions. At parity of Ms, the color and specific star formation rate (sSFR) distributions of the samples are similar, specially between field and group centrals. Furthermore, we find that the stellar-to-halo mass (Ms-Mh) relation of isolated galaxies does not depend on the color, sSFR and morphological type. For systems without satellites, the Ms-Mh relation steepens at high halo masses compared to group centrals, which is a consequence of assuming a one-to-one relation between group total stellar mass and halo mass. Under the same assumption, the scatter around the Ms-Mh relation of centrals with satellites increases with halo mass. Our results suggest that the mass growth of central galaxies is mostly driven by the halo mass, with environment and mergers playing a secondary role.

description: The purpose of the present work was twofold. We explained and analysed in depth the concept of quantum anomalies in quantum field theories, as well as some mechanisms for anomaly cancellation in effective field theories. This helped lay the foundations for studying and discussing in some detail a possible extension of the Standard Model of elementary particles which involved an anomalous Z ′ boson, an axion and generalised Chern-Simons terms. The proposed extension implies some conditions on the possible existence of anomalous Z ′ bosons which can be indirectly tested by means of the known Standard Model couplings. Furthermore, this model leads to additional contributions to the g − 2 of leptons which had not hitherto been computed. Therefore, this theory may be of some phenomenological interest. We concluded that the anomalous contribution to the g-2 of the muon becomes dominant in regions of the parameter space which are compatible with the experimenatl data.

description: The magnetic responses of a spin-1/2 ladder doped with non-magnetic impurities are studied using various methods and including the regime where frustration induces incommensurability. Several improvements are made on the results of the seminal work of Sigrist and Furusaki [J. Phys. Soc. Jpn. 65, 2385 (1996)]. Deviations from the Brillouin magnetic curve due to interactions are also analyzed. First, the magnetic profile around a single impurity and effective interactions between impurities are analyzed within the bond-operator mean-field theory and compared to density-matrix renormalization group calculations. Then, the temperature behavior of the Curie constant is studied in details. At zero-temperature, we give doping-dependent corrections to the results of Sigrist and Furusaki on general bipartite lattice and compute exactly the distribution of ladder cluster due to chain breaking effects. Using exact diagonalization and quantum Monte-Carlo methods on the effective model, the temperature dependence of the Curie constant is compared to a random dimer model and a real-space renormalization group scenario. Next, the low-part of the magnetic curve corresponding to the contribution of impurities is computed using exact diagonalization. The random dimer model is shown to capture the bulk of the curve, accounting for the deviation from the Brillouin response. At zero-temperature, the effective model prediction agrees relatively well with density-matrix renormalization group calculations. Finite-temperature effects are displayed within the effective model and for large depleted ladder models using quantum Monte-Carlo simulations. In all, the effect of incommensurability does not display a strong qualitative effect on both the magnetic susceptibility and the magnetic curve. Consequences for experiments on the BiCu2PO6 compound and other spin-gapped materials are briefly discussed.
