description: In this article, we intend to find a specific model which can satisfy the further refining dS swampland conjecture and scalar weak gravity conjecture (SWGC) simultaneously, in particular, Higgs inflation model and its two extensions: Higgs-Dilaton model and Palatini Higgs inflation. We find that although Higgs inflation model and Higgs-Dilaton model could satisfy the further refining dS swampland conjecture, the two models cannot satisfy SWGC and its strong version. While Palatini Higgs inflation could satisfy these conjectures simultaneously. Therefore Palatini Higgs inflation could be a "real" inflation model of the universe.

description: We provide a comprehensive study on the non-Markovian dynamics of the black hole phase transitions based on the underlying free energy landscape. By assuming that the transition processes between different black hole states are stochastic, the non-Markovian dynamics of the black hole phase transition is governed by the generalized Langevin equation with the time-dependent friction that represents the memory effect from the effective thermal bath when the timescale of the system is comparable or shorter than the timescale of the effective thermal bath. We consider the first passage problem associated with the black hole phase transitions and derive the analytical expressions of the mean first passage time in the weak, intermediate, and large friction regimes. As the concrete examples, we study the effects of three types of time dependent friction kernel (delta function friction, exponentially decayed friction, and oscillatory friction) on the dynamics of Hawking-Page phase transition and the small/large RNAdS black hole phase transition. we found that there is a kinetic turnover point for each type of friction kernel when the friction strength varies. For the exponentially decayed friction kernel, it is shown that the non-Markovian effect slows down the phase transition dynamics in the weak friction regime and speeds up the transition process in the strong friction regime. For the oscillating decayed friction kernel, we found kinetic resonances when the oscillating frequency of the effective thermal bath is equal to the oscillating frequency of the black hole state in the initial potential well on the free energy landscape.

description: The ANTARES telescope, with a duty cycle close to unity and a full hemisphere of the sky at all the times visible, is well suited to detect neutrinos produced in astrophysical transient sources. Assuming a known neutrino production period, the background and the sensitivity can be drastically improved by selecting a narrow time window around it. GRBs, μ-quasars and AGNs are particularly attractive potential neutrino point sources since neutrinos and gamma-rays may be produced in hadronic interactions with the surrounding medium as they are the most likely sources of the observed ultra high energy cosmic rays. A strong correlation between the gamma-ray and the neutrino fluxes is expected in this scenario. ANTARES data has been analysed in various transient source analyses with the goal of detecting cosmic neutrinos from GRBs, μ-quasars and AGNs. The sensitivity of a standard time-integrated point source search can be improved by a factor 2-3 by looking for neutrinos only during the most probable emission time. This information can be provided by the different satellite telescope types on the X-rays and gamma-rays wavelengths. The results of these different analyses will be presented.

description: We theorize the surface step characterization by reflected incoherent-light differential interference microscopy with consideration of the optical diffraction effect. With the integration of localization analysis, we develop a quantitative differential interference optical system, by which we demonstrate that the axial resolution of measuring surface height variation is sensitive to the shear distance between the two spatially differentiated beams. We fabricate three nanometer-size steps by photolithography, and successfully characterize their 1D height variations with 0.13 nm Hz^(-1/2) axial precision. Our result suggests that the optical differential interference microscopy can be used for real-time characterization of surface structure with a subnanometer accuracy and a large field of view, which is greatly beneficial to the surface characterization of micro/nano-electromechanical systems.

description: The toric fiber product is an operation that combines two ideals that are homogeneous with respect to a grading by an affine monoid. The Segre product is a related construction that combines two multigraded rings. The quotient ring by a toric fiber product of two ideals is a subring of the Segre product, but in general this inclusion is strict. We contrast the two constructions and show that any Segre product can be presented as a toric fiber product without changing the involved quotient rings. This allows to apply previous results about toric fiber products to the study of Segre products. We give criteria for the Segre product of two affine toric varieties to be dense in their toric fiber product, and for the map from the Segre product to the toric fiber product to be finite. We give an example that shows that the quotient ring of a toric fiber product of normal ideals need not be normal. In rings with Veronese type gradings, we find examples of toric fiber products that are always Segre products, and we show that iterated toric fiber products of Veronese ideals over Veronese rings are normal.

description: We study approaches for the exact solution of the \NP--hard minimum spanning tree problem under conflict constraints. Given a graph $G(V,E)$ and a set $C \subset E \times E$ of conflicting edge pairs, the problem consists of finding a conflict-free minimum spanning tree, i.e. feasible solutions are allowed to include at most one of the edges from each pair in $C$. The problem was introduced recently in the literature, with several results on its complexity and approximability. Some formulations and both exact and heuristic algorithms were also discussed, but computational results indicate considerably large duality gaps and a lack of optimality certificates for benchmark instances. In this paper, we build on the representation of conflict constraints using an auxiliary conflict graph $\hat{G}(E,C)$, where stable sets correspond to conflict-free subsets of $E$. We introduce a general preprocessing method and a branch and cut algorithm using an IP formulation with exponentially sized classes of valid inequalities for both the spanning tree and the stable set polytopes. Encouraging computational results indicate that the dual bounds of our approach are significantly stronger than those previously available, already in the initial LP relaxation, and we are able to provide new feasibility and optimality certificates.
title: Membrane fluidity and epidermal growth factor receptor function in breast cancer
Creators: name: Lindsay, Blythe
Publisher: name: University of Glasgow
Year: 1998

description: The epidermal growth factor receptor (EGFR) has been implicated in the growth and development of a number of human cancers including breast cancer. The activity and expression of membrane associated proteins such as the EGFR may be modulated by the physical state of the membrane. Activation of the EGFR depends on the lateral diffusion and dimerisation of receptor monomers. Changes in membrane fluidity may therefore affect activation of the EGFR and hence growth signalling via this receptor. Using the technique of fluorescence recovery after photobleaching, the lateral diffusion of number of fluorescent lipid probes was studied in three breast cancer cell lines (MCF-7, MDA-MB-231 and MCF-7AdrR). The antiestrogen drug tamoxifen which is widely used in the treatment of breast cancer, was demonstrated to decrease membrane fluidity in breast cancer cells e.g. in MCF-7 cells a 24 hour incubation with l0-6M tamoxifen decreased the lateral diffusion coefficient of the AF18 probe from 203 xl0-10cm2/s to 15.4 xl0-10cm2/s. Tamoxifen treatment had a general effect on membrane fluidity which was observed using different lipid probes and was not dependent on the estrogen receptor status of the cell line. Tamoxifen's ability to decrease membrane fluidity may be due to its ability to adopt a conformation which resembles the steroid nucleus. The steroids cholesterol, 17?-estradiol and the steroidal antiestrogen ICIl82,780 all had a similar effect on membrane fluidity. Tamoxifen has previously been reported to have several actions unrelated to inhibition of estrogen action. Tamoxifen can inhibit the growth of cells in the complete absence of estrogens and also inhibit cells which do not express the estrogen receptor. Tamoxifen can inhibit EGF-stimulated growth of MCF-7 breast cancer cells by a mechanism distinct from induction of TGF? production. Tamoxifen had no effect on the cell surface expression or affinity of the EGFR and it did not inhibit the EGFR tyrosine kinase activity in isolated cell membranes. However, in intact cells tamoxifen treatment inhibited EGFR autophosphorylation. This effect could be due to stabilisation of the membrane by tamoxifen and consequent reduction in the lateral diffusion of the EGF receptor, reducing dimerisation and autophosphorylation of the receptor. This would reduce growth stimulation initiated via the EGFR. Tamoxifen can be demonstrated to reduce EGFR mobility in A431 cells. These cells have elevated levels of EGFR which allow a sufficient level of signal for FRAP measurements of receptor mobility. It is therefore possible that tamoxifen's membrane effects contribute to its anticancer action by interfering with EGFR function. The rate of internalisation of the EGFR was not altered by tamoxifen treatment which suggests that EGFR lateral diffusion is not a rate-limiting factor in receptor internalisation. Tamoxifen treatment also had no effect on the adriamycin sensitivity of the drug resistant cell line MCF-7AdrR.

description: We formulate a quantization commutes with reduction principle in the setting where the Lie group $G$, the symplectic manifold it acts on, and the orbit space of the action may all be noncompact. It is assumed that the action is proper, and the zero set of a deformation vector field, associated to the momentum map and an equivariant family of inner products on the Lie algebra $\mathfrak{g}$ of $G$, is $G$-cocompact. The central result establishes an asymptotic version of this quantization commutes with reduction principle. Using an equivariant family of inner products on $\mathfrak{g}$ instead of a single one makes it possible to handle both noncompact groups and manifolds, by extending Tian and Zhang's Witten deformation approach to the noncompact case.

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Physical education and development curriculum and pedagogy

description: This thesis comprises of a collection of four research studies in the area ofmotivational climate in physical education (PE). In the first study, a computer based observational measure of the teaching behaviours that influence motivational climate(TARGET) was developed and the degree of congruence between the observationalmeasure and pupils' and teachers' subjective perceptions of the motivational climatewas evaluated. Results revealed mastery and performance involving teaching behaviours, congruency between teaching behaviours and subjective perceptions ofthe climate, and significant differences between teachers' and pupils' perceptions ofthe motivational climate. The second study further validated the measure of teaching behaviours by comparing teacher behaviours and pupils' perceptions of themotivational climate in a cross-cultural study. Results indicated significantly higherlevels of performance involving teaching behaviours and higher levels of a perceivedperformance climate in Singapore compared to the UK. Based on findings related to the authority structure in the cross-cultural study, the third study examined the effects of different teaching styles on the TARGET behaviours and pupils' focus groupresponses in PE lessons in the UK. Results revealed that pupil-centred teaching stylesresulted in more mastery involving teaching behaviours and more adaptivemotivational responses than the more teacher-centred style. Based on these findings,the final study instigated a mastery intervention programme for teacher educationbased on self-observation of filmed PE lessons and evaluated its effect on the TARGET behaviours, pupils' perceptions of the motivational climate and cognitiveand affective responses. The mastery intervention programme was successful infostering more mastery involving teaching behaviours. Contrary to the hypothesis,pupils' perceptions of the motivational climate were more performance involved post-intervention, which may have been due to the public nature of the recognitionand evaluation of effort and improvement (mastery coded). Further, results revealed that low affect pupils significantly increased their cognitive and affective responses from pre- to post-intervention.

description: Doping is one of the most relevant paths to tune the functionality of cuprates, it determines carrier density and the overall physical properties of these impressive superconducting materials. We present an oxygen doping study of YBa$_2$Cu$_3$O$_{7-δ}$ (YBCO) thin films from underdoped to overdoped state, correlating the measured charge carrier density, $n_\textrm{H}$, the hole doping, $p$, and the critical current density, $J_\textrm{c}$. Our results show a continuous increase of $J_\textrm{c}$ with charge carrier density, reaching 90 MA/cm$^2$ at 5 K for $p$-doping at the Quantum Critical Point (QCP), linked to an increase of the superconducting condensation energy. The ultra-high $J_\textrm{c}$ achived corresponds to a third of the depairing current, i.e. a value 60 % higher than ever reported in YBCO films. The overdoped regime is characterized by a sudden increase of $n_\textrm{H}$, associated to the reconstruction of the Fermi-surface at the QCP. Overdoping YBCO opens a promising route to extend the current carrying capabilities of REBCO coated conductors for applications.

description: Matchbox manifolds are foliated spaces with totally disconnected transversals. Two matchbox manifolds which are homeomorphic have return equivalent dynamics, so that invariants of return equivalence can be applied to distinguish non-homeomorphic matchbox manifolds. In this work we study the problem of showing the converse implication: when does return equivalence imply homeomorphism? For the class of weak solenoidal matchbox manifolds, we show that if the base manifolds satisfy a strong form of the Borel Conjecture, then return equivalence for the dynamics of their foliations implies the total spaces are homeomorphic. In particular, we show that two equicontinuous $\mT^n$--like matchbox manifolds of the same dimension are homeomorphic if and only if their corresponding restricted pseudogroups are return equivalent. At the same time, we show that these results cannot be extended to include the "\emph{adic}-surfaces", which are a class of weak solenoids fibering over a closed surface of genus 2.

description: We present a general framework to study the simultaneous estimation of multiple phases in the presence of noise as a discretized model for phase imaging. This approach can lead to nontrivial bounds of the precision for multiphase estimation. Our results show that simultaneous estimation (SE) of multiple phases is always better than individual estimation (IE) of each phase even in noisy environment. However with $d$ being the number of phases, the $O(d)$ advantage in the variance of the estimation, with which SE outperforms IE schemes for noiseless processes, may disappear asymptotically. When noise is low, those bounds recover the Heisenberg scale with the $O(d)$ advantage. The utility of the bound of multiple phase estimation for photon loss channels is exemplified.

description: Converting low-frequency electrical signals into much higher frequency optical signals has enabled modern communications networks to leverage both the strengths of microfabricated electrical circuits and optical fiber transmission, allowing information networks to grow in size and complexity. A microwave-to-optical converter in a quantum information network could provide similar gains by linking quantum processors via low-loss optical fibers and enabling a large-scale quantum network. However, no current technology can convert low-frequency microwave signals into high-frequency optical signals while preserving their fragile quantum state. For this demanding application, a converter must provide a near-unitary transformation between different frequencies; that is, the ideal transformation is reversible, coherent, and lossless. Here we demonstrate a converter that reversibly, coherently, and efficiently links the microwave and optical portions of the electromagnetic spectrum. We use our converter to transfer classical signals between microwave and optical light with conversion efficiencies of ~10%, and achieve performance sufficient to transfer quantum states if the device were further precooled from its current 4 kelvin operating temperature to below 40 millikelvin. The converter uses a mechanically compliant membrane to interface optical light with superconducting microwave circuitry, and this unique combination of technologies may provide a way to link distant nodes of a quantum information network.

description: In this article we study two-dimensional Dirac Hamiltonians with non-commutativity both in coordinates and momenta from an algebraic perspective. In order to do so, we consider the graded Lie algebra $\mathfrak{sl}(2|1)$ generated by Hermitian bilinear forms in the non-commutative dynamical variables and the Dirac matrices in $2+1$ dimensions. By further defining a total angular momentum operator, we are able to express a class of Dirac Hamiltonians completely in terms of these operators. In this way, we analyze the energy spectrum of some simple models by constructing and studying the representation spaces of the unitary irreducible representations of the graded Lie algebra $\mathfrak{sl}(2|1)\oplus \mathfrak{so}(2)$. As application of our results, we consider the Landau model and a fermion in a finite cylindrical well.

Apart from the leading-order factorizable contributions, we also take into account various QCD corrections and the hard-spectator diagrams. With the inclusion of these sizable corrections, our theoretical results for CP-averaged branching ratios, polarization fractions, CP-violating asymmetries, and relative phases are in good consistency with the available data. Based on the global agreement, we further explore the penguin contributions and point out that the $ϕ_s$ extracted from $B_s\to J/ψϕ$ can be shifted away by ${\cal O}(10^{-3})$.

description: A perfect coloring (equivalent concepts are equitable partition and partition design) of a graph $G$ is a function $f$ from the set of vertices onto some finite set (of colors) such that every node of color $i$ has exactly $S(i,j)$ neighbors of color $j$, where $S(i,j)$ are constants, forming the matrix $S$ called quotient. If $S$ is an adjacency matrix of some simple graph $T$ on the set of colors, then $f$ is called a covering of the target graph $T$ by the cover graph $G$. We characterize all coverings by the infinite square grid, proving that every such coloring is either orbit (that is, corresponds to the orbit partition under the action of some group of graph automorphisms) or has twin colors (that is, two colors such that unifying them keeps the coloring perfect). The case of twin colors is separately classified. Keywords: perfect coloring, equitable partition, partition design, square grid, rectangular grid, wallpaper group, twin colors, graph covering

description: Information and Communication Technologies (ICTs) are any electronic tools and software that is used to support lecturers while teaching and students while learning. This study aims to provide an in-depth analysis of lecturers' attitudes towards, and use of, ICT for teaching at Jordanian public universities. Four Jordanian public universities have been investigated in this matter. Mixed methods have been used to collect data, as attitude survey of 448 lecturers,semi-structured interviews of 20 lecturers, and focus group interviews of 15 lecturers have been conducted. Results of the study indicate positive attitudes and high levels of ICT use inteaching and learning. The results also revealed a medium effect of factors affect ICT use inteaching and learning. Lecturers believe that ICT use saves time and efforts and helps themgaining new knowledge and skills, while they believe that the lack of technological infrastructure, lack of support, lack of training and lack of financial resources are the most important factors that have huge impact on ICT in teaching and learning. It was concluded that it is important to overcome the negative factors by adopting clear vision about ICT integration based on the current situation and the desired one, and to adopting flexible plans that respond to social, cultural, and economic changes. It was concluded also that technology, pedagogy and content intersection is substantial factor that guarantee effective teaching and learning, taking in consideration incentives and recognition effects on the lecturers' performance.

description: We present cm-band and mm-band afterglow observations of five long-duration $γ$-ray bursts (GRBs; GRB 130131A, 130420B, 130609A, 131229A, 140713A) with dust-obscured optical afterglow emission, known as "dark" GRBs. We detect the radio afterglow of two of the dark GRBs (GRB 130131A and 140713A), along with a tentative detection of a third (GRB 131229A) with the Karl G. Jansky Very Large Array (VLA). Supplemented by three additional VLA-detected dark GRBs from the literature, we present uniform modeling of their broadband afterglows. We derive high line-of-sight dust extinctions of $A_{V, \rm GRB} \gtrsim 2.2 - 10.6~{\rm mag}$. Additionally, we model the host galaxies of the six bursts in our sample, and derive host galaxy dust extinctions of $A_{V, \rm Host} \approx 0.3-4.7~{\rm mag}$. Across all tested $γ$-ray (fluence and duration) and afterglow properties (energy scales, geometries and circumburst densities), we find dark GRBs to be representative of more typical unobscured long GRBs, except in fluence, for which observational biases and inconsistent classification may influence the dark GRB distribution. Additionally, we find that $A_{V, \rm GRB}$ is not related to a uniform distribution of dust throughout the host, nor to the extremely local environment of the burst, indicating that a larger scale patchy dust distribution is the cause of the high line-of-sight extinction. Since radio observations are invaluable to revealing heavily dust-obscured GRBs, we make predictions for the detection of radio emission from host star formation with the next generation VLA.

title: Designing Pickering Emulsions for Interfacial Catalysis
Creators: name: Stock, Sebastian
Publisher: name: UNSPECIFIED
Year: 2022

description: Pickering emulsions (PEs) are emulsions stabilized by solid or soft (nano-)particles. The high adsorption energy of the particles at the interface results in outstanding stability of PEs. This attribute makes them ideal candidates as an environment for interfacial catalysis. In PEs that are used for interfacial catalysis, usually, a water-soluble catalyst is enclosed in water droplets that are surrounded by the substrate/product containing oil phase. The reaction takes place at the interface of the droplets. The large internal interfacial area of PEs benefits the contact between substrate and catalyst, while the catalyst itself is conserved and protected in the dispersed phase. This increases the product yield and reduces the catalyst loss. Most important, the inherent stability of PEs allows the application of energy-efficient separation strategies, e. g., membrane filtration, to retain the catalyst phase and simultaneously extract the product phase. Despite the growing interest in this topic over the last decade, the connection between emulsion structure and reaction performance remains unclear and general conclusions are missing. This thesis addresses the influence of the emulsion structure on the reaction and filtration performance and suggests a new improved PE structure based on the gained findings. It resembles a bottom-up approach: First, the used nano-particles are characterized regarding their size, charge, hydrophobicity, density and other geometrical characteristics. As a model system, mono-disperse silica nano-spheres (SNs) are synthesized to enable the calculation of values for the particle coverage and the particle-liquid contact area in the PEs. Second, these particles are used to stabilize water in 1-dodecene emulsions and a connection between the nano-scale particle properties and the micro-scale PE structure is drawn. Third, the PEs are tested as an environment for the hydroformylation of 1-dodecene into tridecanal via the water-soluble ligand-metal catalyst Rhodium-Sulfoxantphos and subsequent membrane filtration is carried out. The knowledge about the geometry and structure of the PEs enables the development of a detailed and quantitative model of the reaction process. Finally, a novel emulsion structure is designed based on the findings by combining solid hydrophobic SNs and soft hydrophilic microgel particles (MGs) to synergistically stabilize PEs. The hydrophobic SNs enable the formation of water in oil emulsions while MGs act as a spacer between the SNs to improve the catalyst-substrate contact area. These findings may contribute to a fundamental understanding and offer new impulses for the optimization of interfacial catalysis in PEs.
Trans Students in Italian Schools: Challenges and Best Practices

description: Scientific literature focusing on the experience of trans students highlights how schools are a hostile place for trans people, who are subjected to repeated forms of physical and verbal aggression, bullying, and transphobic harassment by the peer group, teaching, and non-teaching staff. To counter these issues and recognise the identity and needs of trans people, schools have introduced the alias career, a tool already present in Italian universities since 2012. The device outlines good practices to protect the well-being of transgender students and improve their school experience. The regulations of the institutes that have introduced the alias career show that in Italy, the trans experience is still strongly pathologised to the extent that medical-psychological documentation is often required for its activation. Moreover, many good practices are absent or implemented incorrectly, such as toilet access, changing rooms, or training for the school staff and the student body. With this article, the authors, by considering the Italian education system's peculiarities, propose good practices that can help improve the alias career by supplementing it with new proposals that allow students to be recognised and protected during their years of schooling. A further aim is to guide the school staff in responding to the needs of trans pupils and bringing change within the school context by restructuring cisnormative value systems.

description: A finitely generated subgroup Γ of a real Lie group G is said to be Diophantine if there is β> 0 such that non-trivial elements in the word ball B_Γ(n) centered at the identity never approach the identity of G closer than |B_Γ (n)|^{-β}. A Lie group G is said to be Diophantine if for every k > 0, a random k-tuple in G generates a Diophantine subgroup. Semi-simple Lie groups are conjectured to be Diophantine but very little is proven in this direction. We give a characterization of Diophantine nilpotent Lie groups in terms of the ideal of laws of their Lie algebra. In particular we show that nilpotent Lie groups of class at most 5, or derived length at most 2, as well as rational nilpotent Lie groups are Diophantine. We also find that there are non Diophantine nilpotent and solvable (non nilpotent) Lie groups.

description: Three-dimensional (3D) topological spin textures emerge as promising quasi-particles for encoding information in future spintronic devices. The third dimension provides more malleability regarding their magnetic properties as well as more flexibility for potential applications. However, the stabilization and characterization of such quasi-particles in easily implementable systems remain a work in progress. Here we observe a new type of 3D magnetic textures that we called skyrmionic cocoons that sits in the interior of magnetic thin films multilayers and possesses a characteristic ellipsoidal shape. Interestingly, these cocoons can coexist with more standard `tubular' skyrmions going through all the multilayer as evidenced by the existence of two very different contrasts in the MFM images recorded at room temperature. The presence of these novel skyrmionic textures as well as the understanding of their layer resolved chiral and topological properties have been investigated by micromagnetic simulations. In order to experimentally stabilize the combination of 3D skyrmion tubes and cocoons, we have elaborated metallic multilayers in which the magnetic properties, notably the anisotropy, of the magnetic films in the stacks is varied depending on their vertical position. Finally, in complement to the magnetic imaging, we also measure the magneto-resistive response of the multilayers as a function of the magnetic field, and succeed to fit its evolution using the 3D micromagnetic simulations as inputs for the magnetic configuration. The excellent agreement that is reached brings additional evidence of the presence of skyrmionic cocoons that hence can be electrically detected.

description: We use geometric arguments to prove explicit bounds on the mean oscillation for two important rearrangements on $\mathbb{R}^n$. For the decreasing rearrangement $f^*$ of a rearrangeable function $f$ of bounded mean oscillation (BMO) on cubes, we improve a classical inequality of Bennett--DeVore--Sharpley, $\|f^*\|_{BMO(\mathbb{R}_+)}\leq C_n \|f\|_{BMO(\mathbb{R}^n)}$, by showing the growth of $C_n$ in the dimension $n$ is not exponential but at most of the order of $\sqrt{n}$. This is achieved by comparing cubes to a family of rectangles for which one can prove a dimension-free Calderón--Zygmund decomposition. By comparing cubes to a family of polar rectangles, we provide a first proof that an analogous inequality holds for the symmetric decreasing rearrangement, $Sf$.
