description: We investigate two-dimensional frustrated Heisenberg magnets using non-perturbative renormalization group techniques. These magnets allow for point-like topological defects which are believed to unbind and drive either a crossover or a phase transition which separates a low temperature, spin-wave dominated regime from a high temperature regime where defects are abundant. Our approach can account for the crossover qualitatively and both the temperature dependence of the correlation length as well as a broad but well defined peak in the specific heat are reproduced. We find no signatures of a finite temperature transition and an accompanying diverging length scale. Our analysis is consistent with a rapid crossover driven by topological defects.

Background-oriented Schlieren technique with vector tomography for measurement of axisymmetric pressure fields of laser-induced underwater shock waves

description: This study aims to overcome the problems that existing background-oriented schlieren (BOS) techniques based on computed tomography (CT-BOS) face when measuring pressure fields of laser-induced underwater shock waves. To do this, it proposes a novel BOS technique based on vector tomography (VT-BOS) of an axisymmetric target. The remarkable feature of the proposed technique is the reconstruction of an axisymmetric vector field with nonzero divergence, such as the field of a laser-induced underwater shock wave. This approach is based on an approximate relation between the projection of the axisymmetric vector field and the reconstructed vector field. For comparison, the pressure fields of underwater shock waves are measured with VT-BOS, CT-BOS, and a needle hydrophone. It is found that VT-BOS is significantly better than CT-BOS in terms of better convergence, less dependence on the spatial resolution of the acquired images, and lower computational cost. The proposed technique can be applied not only to fluid dynamical fields, but also to other axisymmetric targets in other areas, such as electromagnetics and thermodynamics.

An investigation into the effectiveness of the Secondary Special Educational Needs Co-ordinator (SENCo) role in Wales: The perspective of professionals identified through case studies
Creators: name: Duncan, Heather
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Special education and disability

description: The current statutory framework in Wales for supporting learners with Special Educational Needs (SEN) is centred on the role of the Special Educational Needs Co-ordinator (SENCo). No research has been undertaken in Wales into the nature of the current role, the duties and responsibilities or the factors that impact on their effectiveness to undertake the role. This is what this research aimed to address. The intention was to provide the Welsh Government (WG) with evidence to help identify the strengths and challenges with the current statutory arrangements regarding this key role. It would support the identification of the impact which any statutory changes might potentially have on practice in secondary schools in Wales. Research into the factors that impact on the current role would make a significant contribution to the unfolding professional debate and contribute to a way forward for this complex agenda. In my professional role, I had an involvement with the developing national agenda. This led to me developing a personal and professional interest in ensuring there was a better understanding of current practice that could serve to inform projected changes in legislation. This research investigated the current secondary SENCo role in two large Local Authorities in South East Wales. A case study approach was employed using semi-structured questionnaires and interviews over a six month period. The research findings support a recommendation that before any revision to legislation takes place, there should be an examination of the current demands on practitioners within the current statutory framework. A shared understanding of what is meant by effective practice and an evaluation of what effective practices currently exist may help shape better practice across Wales. It is also recommended that there should be greater national clarity regarding expectations on what any appointed post holder is intended to achieve in the role.

description: While the properties and the shape of the ground state of a gas of ultracold bosons are well understood in harmonic potentials, they remain for a large part unknown in the case of random potentials. Here, we use the localization-landscape (LL) theory to study the properties of the solutions to the Gross-Pitaevskii equation (GPE) in one-dimensional (1D) speckle potentials. In the cases of attractive interactions, we find that the LL allows one to predict the position of the localization center of the ground state (GS) of the GPE. For weakly repulsive interactions, we point out that the GS of the quasi-1D GPE can be understood as a superposition of a finite number of single-particle states, which can be computed by exploiting the LL. For intermediate repulsive interactions, we introduce a Thomas-Fermi-like approach for the GS which holds in the smoothing regime, well beyond the usual approximation involving the original potential. Moreover, we show that, in the Lifshitz glass regime, the particle density and the chemical potential can be well estimated by the LL. Our approach can be applied to any positive-valued random potential endowed with finite-range correlations and can be generalized to higher-dimensional systems.

description: We study the axion in three-dimensional topological insulators with magnetic impurities under finite temperature. We find a stable antiferromagnetic ground state and ferromagnetic metastable state. In both magnetic states, the mass of the axion is found to be up to eV scale and it approaches zero near the phase boundary of the magnetic state. This result applies to both normal and topological insulator phases, i.e., the axion mass is insensitive to the topological states, and it will have a direct impact on the targeted mass range of particle axion dark matter in future experiments.

Floquet formulation of the dynamical Berry-phase approach to non-linear optics in extended systems

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We present a Floquet scheme for the ab-initio calculation of nonlinear optical properties in extended systems. This entails a reformulation of the real-time approach based on the dynamical Berry-phase polarisation [Attaccalite & Grüning, PRB 88, 1-9 (2013)] and retains the advantage of being non-perturbative in the electric field. The proposed method applies to periodically-driven Hamiltonians and makes use of this symmetry to turn a time-dependent problem into a self-consistent time-independent eigenvalue problem. We implemented this Floquet scheme at the independent particle level and compared it with the real-time approach. Our reformulation reproduces real-time-calculated $2^{nd}$ and $3^{rd}$ order susceptibilities for a number of bulk and two-dimensional materials, while reducing the associated computational cost by one or two orders of magnitude.

description: It is known that a minimal teaching set of any threshold function on the twodimensional rectangular grid consists of 3 or 4 points. We derive exact formulae for the numbers of functions corresponding to these values and further refine them in the case of a minimal teaching set of size 3. We also prove that the average cardinality of the minimal teaching sets of threshold functions is asymptotically 7/2. We further present corollaries of these results concerning some special arrangements of lines in the plane.

description: We investigate the long-range behavior of the induced Casimir interaction between two spinless heavy impurities, or polarons, in superfluid cold atomic gases. With the help of effective field theory (EFT) of a Galilean invariant superfluid, we show that the induced impurity-impurity potential at long distance universally shows a relativistic van der Waals-like attraction ($\sim 1/r^7$) resulting from the exchange of two superfluid phonons. We also clarify finite temperature effects from the same two-phonon exchange process. The temperature $T$ introduces the additional length scale $c_s/T$ with the speed of sound $c_s$. Leading corrections at finite temperature scale as $T^6/r$ for distances $r \ll c_s/T$ smaller than the thermal length. For larger distances the potential shows a nonrelativistic van der Waals behavior ($\sim T/r^6$) instead of the relativistic one. Our EFT formulation applies not only to weakly coupled Bose or Fermi superfluids but also to that composed of strongly-coupled unitary fermions with a weakly coupled impurity. The sound velocity controls the magnitude of the van der Waals potential, which we evaluate for the fermionic superfluid in the BCS-BEC crossover.

description: The understanding of morphogenesis in living organisms has been renewed by tremendous progressin experimental techniques that provide access to cell-scale, quantitative information both on theshapes of cells within tissues and on the genes being expressed. This information suggests that ourunderstanding of the respective contributions of gene expression and mechanics, and of their crucialentanglement, will soon leap forward. Biomechanics increasingly benefits from models, which assistthe design and interpretation of experiments, point out the main ingredients and assumptions, andultimately lead to predictions. The newly accessible local information thus calls for a reflectionon how to select suitable classes of mechanical models. We review both mechanical ingredientssuggested by the current knowledge of tissue behaviour, and modelling methods that can helpgenerate a rheological diagram or a constitutive equation. We distinguish cell scale ("intra-cell")and tissue scale ("inter-cell") contributions. We recall the mathematical framework developpedfor continuum materials and explain how to transform a constitutive equation into a set of partialdifferential equations amenable to numerical resolution. We show that when plastic behaviour isrelevant, the dissipation function formalism appears appropriate to generate constitutive equations;its variational nature facilitates numerical implementation, and we discuss adaptations needed in thecase of large deformations. The present article gathers theoretical methods that can readily enhancethe significance of the data to be extracted from recent or future high throughput biomechanicalexperiments.

Effect in the spectra of eigenvalues and dynamics of RNNs trained with Excitatory-Inhibitory constraint

description: In order to comprehend and enhance models that describes various brain regions is important to study the dynamics of trained recurrent neural networks. Including Dales law in such models usually presents several challenges. However, this is an important aspect that allows computational models to better capture the characteristics of the brain. Here we present a framework to train networks using such constraint. Then we have used it to train them in simple decision making tasks. We characterized the eigenvalue distributions of the recurrent weight matrices of such networks. Interestingly, we discovered that the non-dominant eigenvalues of the recurrent weight matrix are distributed in a circle with a radius less than 1 for those whose initial condition before training was random normal and in a ring for those whose initial condition was random orthogonal. In both cases, the radius does not depend on the fraction of excitatory and inhibitory units nor the size of the network. Diminution of the radius, compared to networks trained without the constraint, has implications on the activity and dynamics that we discussed here.

description: The dietary lipid Conjugated Linoleic Acid (CLA) has been the subject of a large body of research in relation to its anti-inflammatory and immunoregulatory role in many cell types and animal models.This study aimed to investigate the effect of a mixtureof the 9:11 and 10:12 isomers of CLAas well as the effect of the 9:11 isomer aloneon the human monocytic cell-line THP-1 cells and human endothelial cells (HUVEC). The effect of supplementation with 2g/day CLA (a 50:50 mixture of 9:11 and 10:12 CLA) and 9:11 CLA in a cross-over trial in subjects with metabolic syndrome was also investigated. Neither CLA nor 9:11 CLA demonstrated any significant endoplasmic reticulum stress or induced apoptosis when cells were treated with the lipids over a concentration range of 20-200μM. Both lipids were able to upregulate gene expression of the nuclear transcription factor PPARγ in both cell types, with CLA having the most marked effect. A significant increase in the PPARγ dependant gene CD36 was also observed and a significant increase in PPARαmRNA was seen with CLA.However, no significant increase in thePPARα dependant CXCL2 gene was observed. PPAR activity in these cells did not appear to be mediated by the induction of endogenous ligands by Cycloxygenase-2. Both lipids were capable of upregulating another transcription factor LXRα, suggesting animportant role for both lipids in cholesterol homeostasis.Both CLA and 9:11 CLA increased mRNA expression for the receptor for advanced glycated end-products (RAGE) and induced solubilisation of the receptor that was not mediated by increasing activation of the metalloproteinase enzyme ADAM10. There was significant induction ofRAGE splice variants secretion in particular esRAGEafter CLA supplementation.The clinical trial demonstrated that dietary supplementation with both isomers induced increased sRAGE secretion, and improved markers of endothelial function and diastolic blood pressure. Improved platelet function was also observed and a non-significant but beneficial trend was observed for HDL-cholesterol and LDL-cholesterol. Multiregression analysis would suggest that the most significant predictor of the reduction in DBP was the increase in sRAGE secretion induced by both CLA and 9:11 CLA.In conclusion,this study would support a beneficial role for CLA and its 9:11 isomer in mediating the pro-atherogenic effects observed in inflammatory disorders such as type 2 Diabetes Mellitus.

We use again bounds from different experiments: relic density, direct detection experiments and indirect detection limits from the search of gamma-ray emissions and positron fluxes. Besides, in this paper we add collider constraints by the ATLAS Collaboration in monojet analysis. Moreover, here we tested our previous results in the light of the aforementioned ATLAS data, which turn out to be the most restrictive forlight dark matter masses (as expected), $m_{\rm DM}

The Jeffreys-Lindley Paradox and Discovery Criteria in High Energy Physics

description: The Jeffreys-Lindley paradox displays how the use of a p-value (or number of standard deviations z) in a frequentist hypothesis test can lead to an inference that is radically different from that of a Bayesian hypothesis test in the form advocated by Harold Jeffreys in the 1930s and common today. The setting is the test of a well-specified null hypothesis (such as the Standard Model of elementary particle physics, possibly with "nuisance parameters") versus a composite alternative (such as the Standard Model plus a new force of nature of unknown strength). The p-value, as well as the ratio of the likelihood under the null hypothesis to the maximized likelihood under the alternative, can strongly disfavor the null hypothesis, while the Bayesian posterior probability for the null hypothesis can be arbitrarily large. The academic statistics literature contains many impassioned comments on this paradox, yet there is no consensus either on its relevance to scientific communication or on its correct resolution. The paradox is quite relevant to frontier research in high energy physics. This paper is an attempt to explain the situation to both physicists and statisticians, in the hope that further progress can be made.

On a fractional Ginzburg-Landau equation and 1/2-harmonic maps into spheres

Year: 2013
Subjects: subject: Analysis of PDEs (math.AP)

description: This paper is devoted to the asymptotic analysis of a fractional version of the Ginzburg-Landau equation in bounded domains, where the Laplacian is replaced by an integro-differential operator related to the square root Laplacian as defined in Fourier space. In the singular Ginzburg-Landau limit, we show that solutions with uniformly bounded energy converge weakly to sphere valued 1/2-harmonic maps, i.e., the fractional analogues of the usual harmonic maps. In addition, the convergence holds in smooth functions spaces away from a (n-1)-rectifiable closed set of finite (n-1)-Hausdorff measure. The proof relies on the representation of the square root Laplacian as a Dirichlet-to-Neumann operator in one more dimension, and on the analysis of a boundary version of the Ginzburg-Landau equation. Besides the analysis of the fractional Ginzburg-Landau equation, we also give a general partial regularity result for stationary 1/2-harmonic maps in arbitrary dimension.

description: We systematically study model-independent constraints on the three generic charged Higgs couplings to $b$-quarks and up-type quarks. While existing LHC searches have focussed on the $tb$ coupling, we emphasize that the LHC plays a crucial role in probing also $ub$ and $cb$ couplings, since constraints from flavor physics are weak. In particular we propose various new searches that can significantly extend the present reach on the parameter space by: i) looking for light charged Higgses that decay into $ub$-quarks, ii) probing charged Higgs couplings to light and top quarks using multi-$b$-jet signatures, iii) looking for single $b$-quarks in low-mass dijet searches, iv) searching for charge asymmetries induced by charged Higgs production via $ub$ couplings.

The Paradox of Two Charged Capacitors -- A New Perspective
Creators: name: Singal, Ashok K.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: It is shown that the famous paradox of two charged capacitors is successfully resolved if all the energy changes in the system are properly considered when some of the charges are transferred from one capacitor to the other. It happens so even when the connecting wire has an identically zero resistance, giving rise to no Ohmic losses in the wire. It is shown that in such a case the "missing energy" goes into the kinetic energy of conducting charges. It is shown that radiation plays no significant role in resolving the paradox. The problem can be formulated and successfully resolved in a novel form, where the capacitance of the system is increased by stretching the plates of the original capacitor, without involving any connecting wires in a circuit. There is an outward self-force due to mutual repulsion among charges stored within each capacitor plate, and the work done by these self-forces during an expansion is indeed equal to the missing energy of the capacitor system.

description: We present a comprehensive optical and near-infrared census of the fields of 90 short gamma-ray bursts (GRBs) discovered in 2005-2021, constituting all short GRBs for which host galaxy associations are feasible ($\approx$ 60% of the total Swift short GRB population). We contribute 245 new multi-band imaging observations across 49 distinct GRBs and 25 spectra of their host galaxies. Supplemented by literature and archival survey data, the catalog contains 335 photometric and 40 spectroscopic data sets. The photometric catalog reaches $3σ$ depths of $\gtrsim 24-27$ mag and $\gtrsim 23-26$ mag for the optical and near-infrared bands, respectively. We identify host galaxies for 84 bursts, in which the most robust associations make up 54% (49/90) of events, while only a small fraction, 6.7%, have inconclusive host associations. Based on new spectroscopy, we determine 17 host spectroscopic redshifts with a range of $z\approx 0.15-1.6$ and find that $\approx$ 25-44% of Swift short GRBs originate from $z>1$. We also present the galactocentric offset catalog for 83 short GRBs. Taking into account the large range of individual measurement uncertainties, we find a median of projected offset of $\approx 7.9$ kpc, for which the bursts with the most robust associations have a smaller median of $\approx 4.9$ kpc. Our catalog captures more high-redshift and low-luminosity hosts, and more highly-offset bursts than previously found, thereby diversifying the population of known short GRB hosts and properties. In terms of locations and host luminosities, the populations of short GRBs with and without detectable extended emission are statistically indistinguishable. This suggests that they arise from the same progenitors, or from multiple progenitors which form and evolve in similar environments. All of the data products are available on the BRIGHT website.

Social exclusion and crime: A critical exploration of sport and its role in crime reduction among adults
Creators: name: Galdes, Maria
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Crime and social justice
Sport and exercise psychology

description: Sport has been promoted as having potential to contribute to crime prevention, rehabilitation and reduction (Coalter 2007; Nichols 2007). This rationale was accelerated by "New" Labour Government's policies (Coalter 2012). The interrelationship between sport, adult crime reduction and social exclusion provide a focus for this thesis. An initial policy review and literature review is followed by two empirical studies which investigate the use of a sports-based programme by an ex-offender (aged 39) and explore the attitudes via semi-structured interviews of gatekeepers (n=21) towards the use of sport for crime reduction purposes with adult populations. Key findings demonstrate that the provision of a sports-based programme for an adult ex-offender has the potential to assist the rehabilitation and resettlement process. There is evidence that the links between sport, career development and employability were particularly important amongst this older age band. There were mixed views from the gatekeepers towards the use of sport for crime reduction, particularly its potential amongst adult delinquents. There were instances where sport was being utilised in crime reduction practices, this was done on an ad hoc basis. Gatekeepers demonstrated concerns over raising expectations of offenders through sports-based qualifications and the public's negative perceptions of sport as an "easy option" for offenders. It is essential to adopt an holistic approach when examining sports within a crime reduction context, concentrating on those problems experienced by individuals engaged in sports-based programmes as opposed to the intervention itself (Crabbe 2000, 2008; Coalter 2012). Any quest to change behaviour patterns associated with crime will involve complex associations which create a myriad of outcomes (Coalter et al. 2000). In order to understand which approaches work for which subjects in what conditions, there is a need to obtain a deeper understanding of the complexities of participant's interactions with initiatives (Morris et al. 2003; Coalter 2012).

description: Many fundamental properties of a quantum system are captured by its Hamiltonian and ground state. Despite the significance of ground states preparation (GSP), this task is classically intractable for large-scale Hamiltonians. Quantum neural networks (QNNs), which exert the power of modern quantum machines, have emerged as a leading protocol to conquer this issue. As such, how to enhance the performance of QNNs becomes a crucial topic in GSP. Empirical evidence showed that QNNs with handcraft symmetric ansatzes generally experience better trainability than those with asymmetric ansatzes, while theoretical explanations have not been explored. To fill this knowledge gap, here we propose the effective quantum neural tangent kernel (EQNTK) and connect this concept with over-parameterization theory to quantify the convergence of QNNs towards the global optima. We uncover that the advance of symmetric ansatzes attributes to their large EQNTK value with low effective dimension, which requests few parameters and quantum circuit depth to reach the over-parameterization regime permitting a benign loss landscape and fast convergence. Guided by EQNTK, we further devise a symmetric pruning (SP) scheme to automatically tailor a symmetric ansatz from an over-parameterized and asymmetric one to greatly improve the performance of QNNs when the explicit symmetry information of Hamiltonian is unavailable. Extensive numerical simulations are conducted to validate the analytical results of EQNTK and the effectiveness of SP.

title: Erroneous Assumptions: Steve Tomasula’s Ascension
Creators: name: Moulthrop, Stuart
Publisher: name: Electronic Book Review
Year: 2023

description: Taking an ironic, Icarian twist on Steve Tomasula's Ascension, Stuart Moulthrop situates Tomasula's novel in a subterranean, encyclopedic lineage that includes print fictions like Joyce’s Ulysses, Dos Passos’ U.S.A. trilogy, Pynchon’s Gravity’s Rainbow, DeLillo’s Underworld, David Foster Wallace’s Infinite Jest, and Zadie Smith’s White Teeth – novels that are, as Edward Mendelson put it, “the products of an epoch in which the world's knowledge is larger than any one person can encompass.” It's an experimental lineage that is, arguably, one of the more noteworthy carryovers from print to digital literature; a genre that Moulthrop (2013) and his near contemporary Michael Joyce (2007) have termed the “novel of internet.”
Energy conservation behaviors in U.S. households: combining top-down and bottom-up approaches
Creators: name: Kumar, Pranay
Publisher: name: No Publisher Supplied
Year: 2023

description: Reducing households’ energy consumption while maintaining physical comfort and well-being is considered important to limit carbon emissions and meet national and global climate policy goals. Many nations and governments are utilizing energy efficiency policies in residential sector due to their important role and potential socio-economic benefits in sustainable energy transition. In this context, it is not only important to understand what are the physical, socio-economic, and behavioral factors underlying residential energy consumption but also to know how it varies across households, regions, and energy sources. In my dissertation, I study human behavioral aspects of residential energy consumption that are relevant for design and evaluation of energy efficiency policies. My research is inspired by a multi-disciplinary public policy perspective that includes insights from environmental psychology, behavioral economics, science technology studies, among others. Following the introduction and a brief overview of the residential energy conservation literature in Chapter 1 and 2 respectively, I present findings from my study using a mix of survey responses and panel electricity data for three years from 155 sample households in Lake county Illinois from Midwest US in Chapter 3. Next, I analyze role of annual household income on efficiency and curtailment behaviors and test their extent and direction in explaining total energy/electricity consumption of US households using cross-sectional nationally representative survey data in Chapter 4. Spillover effects are considered important in understanding the nexus between food, energy, and water (FEW) conservation behaviors and estimating the overall impact of FEW conservation policies. In Chapter 5, I review FEW spillover literature using a systemic thinking lens and present findings from quantitative meta-analysis of empirical studies. Viewed from Lasswell’s stages model, Chapters 3 and 4 touch upon the design part of policymaking, whereas Chapter 5 concerns more with estimation of outcomes and policy evaluation. I rely on a mix of analytical approaches that include structural equation modeling (SEM), cluster analysis, and multivariate linear regression methods depending on specific research hypotheses. In Chapter 6, I summarize findings on residential energy conservation behaviors from different analytical frames and outline my future research plans. I believe that a deeper understanding and comprehensive discussion of energy conservation behaviors will inform policymaking and help in achieving sustainable outcomes.

description: The chiral magnets with topological spin textures provide a rare platform to explore topology and magnetism for potential application implementation. Here, we study the magnetic dynamics of several spin configurations on the monoaxial chiral magnetic crystal $MnNb_3S_6$ via broadband ferromagnetic resonance (FMR) technique at cryogenic temperature. In the high-field forced ferromagnetic state (FFM) regime, the obtained frequency f vs. resonance field Hres dispersion curve follows the well-known Kittel formula for a single FFM, while in the low-field chiral magnetic soliton lattice (CSL) regime, the dependence of Hres on magnetic field angle can be well-described by our modified Kittel formula including the mixture of a helical spin segment and the FFM phase. Furthermore, compared to the sophisticated Lorentz micrograph technique, the observed magnetic dynamics corresponding to different spin configurations allow us to obtain temperature- and field-dependent proportion of helical spin texture and helical spin period ratio L(H)/L(0) via our modified Kittel formula. Our results demonstrated that field- and temperature-dependent nontrivial magnetic structures and corresponding distinct spin dynamics in chiral magnets can be an alternative and efficient approach to uncovering and controlling nontrivial topological magnetic dynamics.

An examination of the role and experiences of middle level academic managers in higher education when implementing organisational change: A case study utilising appreciative inquiry
Creators: name: Carter, Mary
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Educational administration, management and leadership

description: A qualitative case study using Appreciative Inquiry (AI) was undertaken to identify the experiences of middle level academic managers in a UK university when implementing change. First a systematic study and critique of the literature relating to the theoretical framework of Appreciative Inquiry was carried out. Here AI was examined in the context of higher education; the theoretical perspectives that are applied to the management and implementation of change; and the experiences of academics working as managers. Then a series of interviews were carried out and provocative propositions, based on the AI cycle (Cooperrider, Whitney and Stavros, 2008) were generated and circulated for comment. Appreciative Inquiry proved to be an excellent research tool, yielding rich descriptions of the managers' roles at a time of change. Middle level managers primarily implement change without necessarily being privy to the decision-making process which has preceded the change. Since they have no budgetary control or access to any incentives to encourage staff to embrace the change these middle managers need to cajole and persuade staff to participate. They are frequently in a difficult position, as more senior managers expect them to implement change, while their subordinates expect them to support them in their objections to it. The respondents in the study welcomed the opportunity to interact with people from different discipline areas and to try and cohere different programme teams into a department. The fact that frequently they interacted with people on a very personal level was valued, although it could be emotionally draining. Every respondent mentioned student satisfaction as a key motivator and were concerned that good quality teaching should not be compromised by changes in the university system. It is recommended that middle managers be supported by the creation of a cross-university discussion forum and a mentoring scheme.

description: We theoretically analyze measurements of the transient field leaving a cavity as a tool for studying non-Markovian dynamics in cavity quantum electrodynamics (QED). Combined with a dynamical decoupling pulse sequence, transient spectroscopy can be used to recover spectral features that may be obscured in the stationary cavity transmission spectrum due to inhomogeneous broadening. The formalism introduced here can be leveraged to perform in situ noise spectroscopy, revealing a robust signature of quantum noise arising from non-commuting observables, a purely quantum effect.

description: According to the database from the first paper, we select 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies. We study the dependence of galaxies integral parameters, star-formation (SF) and active galactic nuclei (AGN) properties on kinematics of pairs, their structure and large-scale environments. Following main results were obtained: projected radial separation Dp between galaxies correlates with the perturbation level P of the pairs. Both parameters do not correlate with line-of-sight velocity difference dV of galaxies. Dp and P are better measures of interaction strength than dV. The latter correlates with the density of large-scale environment and with the morphologies of galaxies. Both galaxies in a pair are of the same nature, the only difference is that MRK galaxies are usually brighter than their neighbors in average by 0.9 mag. Specific star formation rates (SSFR) of galaxies in pairs with smaller Dp or dV is in average 0.5 dex higher than that of galaxies in pairs with larger Dp or dV. Closeness of a neighbor with the same and later morphological type increases the SSFR, while earlier-type neighbors do not increase SSFR. Major interactions/mergers trigger SF and AGN more effectively than minor ones. The fraction of AGNs is higher in more perturbed pairs and pairs with smaller Dp. AGNs typically are in stronger interacting systems than star-forming and passive galaxies. There are correlations of both SSFRs and spectral properties of nuclei between pair members.
