description: We consider multi-component dark matter in a model where one dark matter component is feebly interacting (FIMP) while the second is weakly interacting (WIMP). The model contains an inert scalar doublet and a complex scalar singlet and features a discrete $Z_4$ symmetry. We determine the parameter space that satisfies theoretical constraints, collider constraints, relic density as well as direct and indirect detection limits. We discuss the possibility to probe the model through collider and astrophysical searches. We find that it is possible that the FIMP forms the dominant DM component, in this case the astrophysical signatures of the WIMP are much suppressed. We also explore the case where the doublet can decay into pairs of singlets leaving only one DM component, the FIMP. These scenarios are constrained by BBN and are best explored at colliders since astrophysical signatures are suppressed.

description: Exploiting the two-point measurement statistics, we propose a quantum measurement scheme of current with limited resolution of electron counting. Our scheme is equivalent to the full counting statistics in the long-time measurement with the ideal resolution, but is theoretically extended to take into account the resolution limit of actual measurement devices. Applying our scheme to a resonant level model, we show that the limited resolution of current measurement gives rise to a positive excess noise, which leads to a deviation from the Johnson-Nyquist relation. The deviation exhibits universal single-parameter scaling with the scaling variable $Q\equiv S_{\rm{}M}/S_0$, which represents the degree of the insufficiency of the resolution. Here, $S_0$ is the intrinsic noise, and $S_{\rm{}M}$ is the positive quantity that has the same dimension as $S_0$ and is defined solely by the measurement scheme. For the lack of the ideal resolution, the deviation emerges for $Q<1$ as $2\exp[-(2π)^2/Q]$ having an essential singularity at $Q=0$, which followed by the square root dependence $\sqrt{Q/4π}$ for $Q\gg1$. Our findings offer an explanation for the anomalous enhancement of noise temperature observed in Johnson noise thermometry.

description: We propose a new data-driven approach for learning the fundamental solutions (Green's functions) of various linear partial differential equations (PDEs) given sample pairs of input-output functions. Building off the theory of functional linear regression (FLR), we estimate the best-fit Green's function and bias term of the fundamental solution in a reproducing kernel Hilbert space (RKHS) which allows us to regularize their smoothness and impose various structural constraints. We derive a general representer theorem for operator RKHSs to approximate the original infinite-dimensional regression problem by a finite-dimensional one, reducing the search space to a parametric class of Green's functions. In order to study the prediction error of our Green's function estimator, we extend prior results on FLR with scalar outputs to the case with functional outputs. Finally, we demonstrate our method on several linear PDEs including the Poisson, Helmholtz, Schrödinger, Fokker-Planck, and heat equation. We highlight its robustness to noise as well as its ability to generalize to new data with varying degrees of smoothness and mesh discretization without any additional training.

description: We study quark and gluon jets separately using public collider data from the CMS experiment. Our analysis is based on 2.3/fb of proton-proton collisions at 7 TeV, collected at the Large Hadron Collider in 2011. We define two non-overlapping samples via a pseudorapidity cut -- central jets with |eta| < 0.65 and forward jets with |eta| > 0.65 -- and employ jet topic modeling to extract individual distributions for the maximally separable categories. Under certain assumptions, such as sample independence and mutual irreducibility, these categories correspond to "quark" and "gluon" jets, as given by a recently proposed operational definition. We consider a number of different methods for extracting reducibility factors from the central and forward datasets, from which the fractions of quark jets in each sample can be determined. The greatest stability and robustness to statistical uncertainties is achieved by a novel method based on parametrizing the endpoints of a receiver operating characteristic (ROC) curve. To mitigate detector effects, which would otherwise induce unphysical differences between central and forward jets, we use the OmniFold method to perform central value unfolding. As a demonstration of the power of this method, we extract the intrinsic dimensionality of the quark and gluon jet samples, which exhibit Casimir scaling, as expected from the strongly-ordered limit. To our knowledge, this work is the first application of full phase space unfolding to real collider data, and one of the first applications of topic modeling to extract separate quark and gluon distributions at the LHC.

description: Applications of the quantum switch on quantum channels have recently become a topic of intense discussion. In the present work, we show that some useless (for communication) channels may provide useful communication under the action of quantum switch for several information-theoretic tasks: quantum random access codes, quantum steering, etc. We demonstrate that the quantum switch can also be useful in preventing the loss of coherence in a system when only coherence-breaking channels are the available channels for communication. We also show that if a useless quantum channel does not provide useful communication even after using a quantum switch, concatenating the channel with another suitable quantum channel, and subsequently using the switch, one may achieve useful communication. Finally, we discuss how the introduction of noise in the quantum switch can reduce the advantage that the switch provides.

description: We theoretically study the coherent nonlinear response of electrons confined in semiconductor quantum wells under the effect of an electromagnetic radiation close to resonance with an intersubband transition. Our approach is based on the time-dependent Schrödinger-Poisson equation stemming from a Hartree description of Coulomb-interacting electrons. This equation is solved by standard numerical tools and the results are interpreted in terms of approximated analytical formulas. For growing intensity, we observe a redshift of the effective resonance frequency due to the reduction of the electric dipole moment and the corresponding suppression of the depolarization shift. The competition between coherent nonlinearities and incoherent saturation effects is discussed. The strength of the resulting optical nonlinearity is estimated across different frequency ranges from mid-IR to THz with an eye to ongoing experiments on Bose-Einstein condensation of intersubband polaritons and to the speculative exploration of quantum optical phenomena such as single-photon emission in the mid-IR and THz windows.

description: We consider correlation functions of single trace operators approaching the cusps of null polygons in a double-scaling limit where so-called $\textit{cusp times}$ $t_i^2 = g^2 \log x_{i-1,i}^2\log x_{i,i+1}^2$ are held fixed and the t'Hooft coupling is small. With the help of stampedes, symbols and educated guesses, we find that any such correlator can be uniquely fixed through a set of coupled lattice PDEs of Toda type with several intriguing novel features. These results hold for most conformal gauge theories with a large number of colours, including planar $\mathcal{N}=4$ SYM.

description: Nonpairwise multi-qubit interactions present a useful resource for quantum information processors. Their implementation would facilitate more efficient quantum simulations of molecules and combinatorial optimization problems, and they could simplify error suppression and error correction schemes. Here we present a superconducting circuit architecture in which a coupling module mediates 2-local and 3-local interactions between three flux qubits by design. The system Hamiltonian is estimated via multi-qubit pulse sequences that implement Ramsey-type interferometry between all neighboring excitation manifolds in the system. The 3-local interaction is coherently tunable over several MHz via the coupler flux biases and can be turned off, which is important for applications in quantum annealing, analog quantum simulation, and gate-model quantum computation.

How to turn around a company in decline: A case study approach
Creators: name: El Sayed, Tamer Mohamed Hassan
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Business process management

description: There is a growing body of research on turnaround management due to adverse global economic circumstances. Research on turnaround management aims to reduce/eliminate business decline.Reviewing the turnaround management literature revealed that it has not yet been able to provide managers and practitioners with reliable guidance,or a step-by-step guide to assist them through the turnaround process. This research aims to identify the key stages of the turnaround process and to select appropriate turnaround strategies in relation to particular factors, e.g. causes of decline. A phenomenological perspective was adopted in this study to investigate the key turnaround management issues in two multiple case studies, followedbya feedback analysis from interviews with a panel of experts. The first case study comprised of 14 large and medium sized UK food manufacturing companies and used secondary sources of evidence. The second in depthcase study involved three companies,using primary evidence through semi-structured interviews.Interviews with turnaround and insolvency practitioners were conducted,to investigate the key issues of the revised model of successful turnarounds in the light of their daily practices and models.A general model and step-by-step guide on how to manage a successful turnaround was developed. The modelidentifies four key stages (i.e. first, decline; second, analysis of decline; third, formulation, implementation and stabilisation of the turnaround planandfourth, recovery and return to growth). Once decline is recognised,a leadership decision is made to initiate the turnaround process, identify major obstacles/problems and select the best actions to stop decline and return to full recovery.The turnaround model can assist turnaround managers in evaluating the viability of a company. It also helps analyse a company’s weaknesses and develop strategies: in the short-term to stopdecline and stabilise the situation; in the longer-term,to identify a company’s strengths and enhance its competitive advantage to achieve recovery and return to growth

description: The low gain avalanche detectors (LGADs) are thin sensors with fast charge collection which in combination with internal gain deliver an outstanding time resolution of about 30 ps. High collision rates and consequent large particle rates crossing the detectors at the upgraded Large Hadron Collider (LHC) in 2028 will lead to radiation damage and deteriorated performance of the LGADs. The main consequence of radiation damage is loss of gain layer doping (acceptor removal) which requires an increase of bias voltage to compensate for the loss of charge collection efficiency and consequently time resolution. The Institute of High Energy Physics (IHEP), Chinese Academy of Sciences (CAS) has developed a process based on the Institute of Microelectronics (IME), CAS capability to enrich the gain layer with carbon to reduce the acceptor removal effect by radiation. After 1 MeV neutron equivalent fluence of 2.5$\times$10$^{15}$ n$_{eq}$/cm$^{2}$, which is the maximum fluence to which sensors will be exposed at ATLAS High Granularity Timing Detector (HGTD), the IHEP-IME second version (IHEP-IMEv2) 50 $μ$m LGAD sensors already deliver adequate charge collection > 4 fC and time resolution < 50 ps at voltages < 400 V. The operation voltages of these 50 $μ$m devices are well below those at which single event burnout may occur.
Talking healthy eating - A study of the dietary practices of mothers and grandmothers
Creators: name: Kwan, Deborah Jane Elizabeth
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Nutrition and dietetics not elsewhere classified

description: Food practices are influenced by numerous factors, including the meanings that food holds and the conception of self and acceptance within a community (O'Neill et al 2004). Generational and socioeconomic differences are also influential with James et al (1997) suggesting that diet has a lifelong effect on the health of socially disadvantaged people leading to "an intergenerational spiral of ill health and handicap." The aim of this study was to identify and evaluate some of the factors that influence the dietary behaviour of women from different generations. A questionnaire was developed from a thematic analysis of interviews with parents and grandparents. The results showed differences in perceptions around dietary practices between two generations of women. The grandmothers chose and enjoyed "healthy" foods more often, and were less influenced by external forces, Mothers were more susceptible to emotional eating and to external influences. The results of the questionnaire were used to inform the focus groups which raised issues around the environments that determine food choice, and the difficulties that lifestyles and working arrangements pose for many women. Women in both familial roles reminisced about eating and feeding patterns and expressed that foods not made "from scratch" promoted guilty feelings and that anything "fried" or processed was automatically rendered nutritionally deficient. In the focus groups there was also an emphasis on the environment and how it impacts on food choice. The data reinforced the belief that psychological as well as social and environmental influences are key in understanding why foods are chosen. Giddens' (1992) theory of structuration has been introduced to explore the impact of environment on food choice while Erikson's (1962) concept of generativity has been identified as an area of research to build on the current findings.

description: Hottopixx, proposed by Bittorf et al. at NIPS 2012, is an algorithm for solving nonnegative matrix factorization (NMF) problems under the separability assumption. Separable NMFs have important applications, such as topic extraction from documents and unmixing of hyperspectral images. In such applications, the robustness of the algorithm to noise is the key to the success. Hottopixx has been shown to be robust to noise, and its robustness can be further enhanced through postprocessing. However, there is a drawback. Hottopixx and its postprocessing require us to estimate the noise level involved in the matrix we want to factorize before running, since they use it as part of the input data. The noise-level estimation is not an easy task. In this paper, we overcome this drawback. We present a refinement of Hottopixx and its postprocessing that runs without prior knowledge of the noise level. We show that the refinement has almost the same robustness to noise as the original algorithm.

description: We prove that SL(3,R) has Strong Banach property (T) in Lafforgue's sense with respect to the Banach spaces that are $θ>0$ interpolation spaces (for the complex interpolation method) between an arbitrary Banach space and a Banach space with sufficiently good type and cotype. As a consequence, every action of SL(3,R) or its lattices by affine isometries on such a Banach space X has a fixed point, and the expanders contructed from SL(3,Z) do not admit a coarse embedding into X. We also prove a quantitative decay of matrix coefficients (Howe-Moore property) for representations with small exponential growth of SL(3,R) on X. This class of Banach spaces contains many superreflexive spaces and some nonreflexive spaces as well. We see no obstruction for this class to be equal to all spaces with nontrivial type.

description: We consider the problem of testing the dimension of uncharacterised classical and quantum systems in a prepare-and-measure setup. Here we assume the preparation and measurement devices to be independent, thereby making the problem non-convex. We present a simple method for generating nonlinear dimension witnesses for systems of arbitrary dimension. The simplest of our witnesses is highly robust to technical imperfections, and can certify the use of qubits in the presence of arbitrary noise and arbitrarily low detection efficiency. Finally, we show that this witness can be used to certify the presence of randomness, suggesting applications in quantum information processing.

description: We provide a perturbative framework to calculate extreme events of non-Markovian processes, by mapping the stochastic process to a two-species reaction diffusion process in a Doi-Peliti field theory combined with the Martin-Siggia-Rose formalism. This field theory treats interactions and the effect of external, possibly self-correlated noise in a perturbation about a Markovian process, thereby providing a systematic, diagrammatic approach to extreme events. We apply the formalism to Brownian Motion and calculate its survival probability distribution subject to self-correlated noise.

description: The charge topology in the fragmentation of $^{10}$C nuclei in a track nuclear emulsion at an energy of 1.2 GeV per nucleon is studied. In the coherent dissociation of $^{10}$C nuclei, about 82% of events are associated with the channel $^{10}$C $\rightarrow$ 2$α+$ 2\emph{p}. The angular distributions and correlations of product fragments are presented for this channel. It is found that among $^{10}$C $\rightarrow$ 2$α+$ 2\emph{p} events, about 30% are associated with the process in which dissociation through the ground state of the unstable $^9$Be$_{g.s.}$ nucleus is followed by $^8$Be$_{g.s.} +$ \emph{p} decays.

description: Dynamic vision sensor (DVS) event camera output is affected by noise, particularly in dim lighting conditions. A theory explaining how photon and electron noise affect DVS output events has so far not been developed. Moreover, there is no clear understanding of how DVS parameters and operating conditions affect noise. There is an apparent paradox between the real noise data observed from the DVS output and the reported noise measurements of the logarithmic photoreceptor. While measurements of the logarithmic photoreceptor predict that the photoreceptor is approximately a first-order system with RMS noise voltage independent of the photocurrent, DVS output shows higher noise event rates at low light intensity. This paper unravels this paradox by showing how the DVS photoreceptor is a second-order system, and the assumption that it is first-order is generally not reasonable. As we show, at higher photocurrents, the photoreceptor amplifier dominates the frequency response, causing a drop in RMS noise voltage and noise event rate. We bring light to the noise performance of the DVS photoreceptor by presenting a theoretical explanation supported by both transistor-level simulation results and chip measurements.

description: Acoustic black hole is becoming an attractive topic in recent years, for it open-up new direction for experimental / observational explorations of black holes. In this work, the gravitational bending of acoustic Schwarzschild black hole is investigated. The gravitational deflection angle of particles traveling along null geodesics, weak gravitational lensing and Einstein ring for acoustic Schwarzschild black hole are carefully studied and analyzed. Particularly, in the calculation of gravitational deflection angle, we resort to two approaches -- the Gauss-Bonnet theorem and the geodesic method. The results show that the gravitational bending effect in acoustic Schwarzschild black hole is enhanced, compared with conventional Schwarzschild black hole. This result indicates that the acoustic black holes may be more easily detectable in gravitational bending effects and weak gravitational lensing observations.

A new international food packaging hygiene model - a model of compliance for self-regulation
Creators: name: Wilks, Elizabeth
Publisher: name: Cardiff Metropolitan University

Subjects: Food packaging, preservation and processing

description: This research is the first of its kind in not only reviewing how the UK food packaging industry introduced a voluntary code of practice for packaging hygiene but also in developing a set of guiding principles for companies to adopt it. Given the context of operating within the food supply where hygiene remains paramount, the challenge for the food packaging industry in the UK was to meet the high hygiene expectations of the food manufacturers and retailers. Prior to the Global Packaging Hygiene Standard, many audits were carried out by food manufacturer and retailer visits measuring against their own individual hygiene criteria. The food and packaging manufacturers spent a great deal of time and money preparing for each audit. They were also faced with rising costs caused by the need to audit a global supply chain. The need for a universal hygiene standard for food packaging was escalated by these rising costs and the need to demonstrate and defend the process in place, beyond reasonable doubt for the food packaging hygiene risk. The BRC (British Retail Consortium), an association representing the British retailer, had already used a working group method for the development of a common UK food hygiene standard (BRC Food standard). It was therefore a logical extension of this to also address the quality and hygiene levels of the packaging being used in food manufacture, storage and distribution. The first universal Global food packaging hygiene standard was launched together with the Institute of Packaging (the UK Packaging Association) in 2001 (BRC & IOP, 2001). The key principles for a model of compliance for companies seeking to adopt this standard are achieved through a variety of research methods: - surveys, audit reports and case studies. Two specific models are used to determine the readiness and evolution of the culture of selected paper and board companies, in implementing this standard. The models used are Cameron and Quinn's competing values framework and Kotter's eight stages of implementation. This research brings together the food and packaging industry, in demonstrating how collaboration throughout the supply chain can provide an effective system for self regulation as well as: - â€¢ providing guidelines for other sectors/industries developing self regulatory standards. These will aid other sectors also having to develop voluntary standards to comply with government regulations. â€¢ establishing key principles for a model of compliance for packaging companies based on the BRC/IOP Global Packaging standard. These principles will support the required growth of the Global Packaging standard worldwide.

description: Linear cosmological observables can be used to probe elastic scattering of dark matter (DM) with baryons. Availability of high-precision data requires a critical reassessment of any assumptions that may impact the accuracy of constraints. The standard formalism for constraining DM-baryon scattering pre-recombination is based on assuming a Maxwell-Boltzmann (MB) velocity distribution for DM. This assumption is not always justified and does not allow for probing DM self-interactions in addition to its interactions with baryons. Lifting the MB assumption requires solving the full collisional Boltzmann equation (CBE), which is highly non-trivial. Earlier work proposed a more tractable Fokker-Planck (FP) approximation to the CBE, but its accuracy remained unknown. In this work, we numerically solve the exact CBE for the first time, in a homogeneous expanding background. We consider DM-baryon scattering cross-sections that are positive power-laws of relative velocity. We derive analytical expressions for the collision operator in the case of isotropic differential scattering cross-sections. We then solve the background CBE numerically and use our solution for the DM velocity distribution to compute the DM-baryon heat-exchange rate, which we compare against those obtained with the MB assumption and FP approximation. Over a broad range of DM-to-baryon mass ratios, we find that the FP approximation leads to a maximum error of 17%, significantly better than the up to 160% error introduced by the MB assumption. While our results strictly apply only to the background evolution, the accuracy of the FP approximation is likely to carry over to perturbations. This motivates its implementation into cosmological Boltzmann codes, where it can supersede the much less accurate MB assumption, and allow for a more general exploration of DM interactions with baryons and with itself.

description: In this work, we find that the complexity of quantum many-body states, defined as a spread in the Krylov basis, may serve as a new probe that distinguishes topological phases of matter. We illustrate this analytically in one of the representative examples, the Su-Schrieffer-Heeger model, finding that spread complexity becomes constant in the topological phase. Moreover, in the same setup, we analyze exactly solvable quench protocols where the evolution of the spread complexity shows distinct dynamical features depending on the topological vs non-topological phase of the initial state as well as the quench Hamiltonian.

In vitro tests for the diagnosis of aspirin and salicylate sensitivity

description: Sensitivity to aspirin, non-steroidal anti-inflammatory drugs (NSAIDs) and also dietary salicylate is an increasingly important and observed phenomenon. The reliable diagnosis of individuals with these disorders is of great importance, given the use of these drugs as a prophylactic medication. Many of the symptoms seen in patients associated with this sensitivity to these drugs include dermatitis, nasal polyps, persistent cough, rhinitis, skin problems, stomach irritation, swelling of face and urticaria are also seen in salicylate intolerance. These symptoms are similar to those seen in the allergic patient, however, the reaction to salicylate is not an allergy. A major clinical problem is that no current method of food intolerance or allergy in vitro testing and diagnosis has currently been established to predict those people with this condition. This study was designed to search for new markers, which could be used to predict with high specificity and sensitivity, subjects with aspirin induced asthma (AIA). This was done by investigating patients with known aspirin sensitivity and comparing them with healthy individuals and atopic non-aspirin sensitive patients. All subjects used (male/females- age range 21-68 years old) were divided into 4 groups (atopic aspirin sensitive, non-atopic aspirin sensitive, atopic non-aspirin sensitive, and healthy volunteers) according to the clinical history and confirmed positive skin test to common allergens. Flow cytometer was used to assess the role of activated basophils in AIA and detect the expression of CD63 in their blood after stimulation of the cells with L-ASA. A posterior rhinomanometer was used to assess a challenge technique that was sensitive to local stimulation by L-ASA. Cytokine (IL-4) expression in lymphocytes was determined using ELISA and IL-4 messenger RNA levels investigated using RT-PCR. The release of PGF2Î± from plasma protein on those patients was detected by ELISA. The results obtained in this study, suggest that up regulation of CD63 expression by aspirin and Nasal airways resistance test (NART) following aspirin challenge, may prove to be useful diagnosis tool in these patients. The study also indicates that lymphocyte responses as evidenced by IL-4 release are not affected by salicylate sensitivity. The significance of these results is also discussed.

description: Understanding the domain wall (DW) dynamics in magnetic nanowires (NW) is crucial for spintronic-based applications demanding the use of DWs as information carriers. This work focuses on the dynamics of a DW displacing along a bent NW with an elliptical shape under the action of spin-polarized electric currents and external magnetic fields. Our results evidence that a curvature gradient induces an exchange-driven effective tangential field responsible for pinning a DW near the maximum curvature point in a NW. The DW equilibrium position depends on the competition between the torques produced by the external stimuli and the curvature-induced effective fields. When the external stimuli are below a certain threshold, the DW follows a damped harmonic oscillation around the equilibrium position. Above this threshold, DW displaces along the NW under an oscillatory translational motion.

description: We study codes with parameters of the ternary Hamming $(n=(3^m-1)/2,3^{n-m},3)$ code, i.e., ternary $1$-perfect codes. The rank of the code is defined to be the dimension of its affine span. We characterize ternary $1$-perfect codes of rank $n-m+1$, count their number, and prove that all such codes can be obtained from each other by a sequence of two-coordinate switchings. We enumerate ternary $1$-perfect codes of length $13$ obtained by concatenation from codes of lengths $9$ and $4$; we find that there are $93241327$ equivalence classes of such codes. Keywords: perfect codes, ternary codes, concatenation, switching.
