description: A recent scanning tunneling microscopy (STM) experiment reports the observation of charge density wave (CDW) with period of approximately 8a in the halo region surrounding the vortex core, in striking contrast to the approximately period 4a CDW that are commonly observed in the cuprates. Inspired by this work, we study a model where a bi-directional pair density wave (PDW) with period 8 is at play. This further divides into two classes, (1) where the PDW is a competing state of the d wave superconductor and can exist only near the vortex core where the d wave order is suppressed, and (2) where the PDW is the primary order, the so called mother state that persists with strong phase fluctuations to high temperature and high magnetic field and lies behind the pseudogap phenomenology. We study the charge density wave structures near the vortex core in these models. We emphasize the importance of the phase winding of the d-wave order parameter. The PDW can be pinned by the vortex core due to this winding and become static. Furthermore, the period 8 CDW inherits the properties of this winding, which gives rise to a special feature of the Fourier transform peak, namely, it is split in certain directions. There are also a line of zeros in the inverse Fourier transform of filtered data. We propose that these are key experimental signatures that can distinguish between the PDW-driven scenario from the more mundane option that the period 8 CDW is primary. We discuss the pros and cons of the options considered above. Finally we attempt to place the STM experiment in the broader context of pseudogap physics of underdoped cuprates and relate this observation to the unusual properties of X ray scattering data on CDW carried out to very high magnetic field.

description: We predict the occurrence of single-photon-induced entanglement and quantum superposition in a hybrid quantum model, introducing an optomechanical coupling into the Rabi model. Originally, it comes from the photon-dependent quantum property of ground state featured by the proposed hybrid model. It associates with a single-photon-induced quantum phase transition, and is immune to the $A^2$ term of the spin-field interaction. Moreover, the obtained quantum superposition state is actual a squeezed cat state, which can give a significant precision enhancement in quantum metrology. This work offers an approach to manipulate entanglement and quantum superposition with a single photon, which might has potential applications in the engineering of new single-photon quantum devices, and also fundamentally broaden the regime of cavity QED.

description: An important family of span programs, st-connectivity span programs, have been used to design quantum algorithms in various contexts, including a number of graph problems and formula evaluation problems. The complexity of the resulting algorithms depends on the largest positive witness size of any 1-input, and the largest negative witness size of any 0-input. Belovs and Reichardt first showed that the positive witness size is exactly characterized by the effective resistance of the input graph, but only rough upper bounds were known previously on the negative witness size. We show that the negative witness size in an st-connectivity span program is exactly characterized by the capacitance of the input graph. This gives a tight analysis for algorithms based on st-connectivity span programs on any set of inputs. We use this analysis to give a new quantum algorithm for estimating the capacitance of a graph. We also describe a new quantum algorithm for deciding if a graph is connected, which improves the previous best quantum algorithm for this problem if we're promised that either the graph has at least kappa > 1 components, or the graph is connected and has small average resistance, which is upper bounded by the diameter. We also give an alternative algorithm for deciding if a graph is connected that can be better than our first algorithm when the maximum degree is small. Finally, using ideas from our second connectivity algorithm, we give an algorithm for estimating the algebraic connectivity of a graph, the second largest eigenvalue of the Laplacian.

description: We propose a method for measuring the cosmological density parameter $Ω$ from the statistics of the divergence field, $θ\equiv H^{-1} ÷v$, the divergence of peculiar velocity, expressed in units of the Hubble constant, $H \equiv 100 h km/s/Mpc$. The velocity field is spatially smoothed over $\sim 10 h^{-1} Mpc$ to remove strongly nonlinear effects. Assuming weakly-nonlinear gravitational evolution from Gaussian initial fluctuations, and using second-order perturbative analysis, we show that $ \propto -Ω^{-0.6} ^2$. The constant of proportionality depends on the smoothing window. For a top-hat of radius R and volume-weighted smoothing, this constant is $26/7-γ$, where $γ=-d\log / d\log R$. If the power spectrum is a power law, $P(k)\propto k^n$, then $γ=3+n$. A Gaussian window yields similar results. The resulting method for measuring $Ω$ is independent of any assumed biasing relation between galaxies and mass. The method has been successfully tested with numerical simulations. A preliminary application to real data, provided by the POTENT recovery procedure from observed velocities favors $Ω\sim 1$. However, because of an uncertain sampling error, this result should be treated as an assessment of the feasibility of our method rather than a definitive measurement of $Ω$.

description: Photons propagating in curved spacetime may, depending on their direction and polarisation, have velocities exceeding the ``speed of light'' c. This phenomenon arises through vacuum polarisation in QED and is a tidal gravitational effect depending on the local curvature. It implies that the Principle of Equivalence does not hold for interacting quantum field theories in curved spacetime and reflects a quantum violation of local Lorentz invariance. These results are illustrated for the propagation of photons in the Reissner-Nordström spacetime characterising a charged black hole. A general analysis of electromagnetic as well as gravitational birefringence is presented.

description: Yb$_2$Si$_2$Al may be a prototype for exploring different aspects of the Shastry-Sutherland lattice, formed by planes of orthogonally coupled Yb ions. Measurements of the magnetic susceptibility find incoherently fluctuating Yb$^{3+}$ moments coexisting with a weakly correlated metallic state that is confirmed by measurements of the electrical resistivity. Increasing signs of Kondo coherence are found with decreasing temperature, including an enhanced Sommerfeld coefficient and Kadowaki-Woods ratio that signal that the metallic state found at the lowest temperatures is a Fermi liquid where correlations have become significantly stronger. A pronounced peak in the electronic and magnetic specific heat indicates that the coupling of the Yb moments to the conduction electrons leads to an effective Kondo temperature that is approximately 30 K. The valence of Yb$_2$Si$_2$Al has been investigated with electron spectroscopy methods. Yb$_2$Si$_2$Al is found to be strongly intermediate valent ($v_F=2.68(2)$ at 80 K). Taken together, these experimental data are consistent with a scenario where a coherent Kondo lattice forms in Yb$_2$Si$_2$Al from an incoherently fluctuating ensemble of Yb moments with incomplete Kondo compensation, and strong intermediate valence character.

High density effective theory on the lattice

description: Long-range interactions in finite density QCD necessitate a non-perturbative approach in order to reliably map out the key features and spectrum of the QCD phase diagram. However, the complex nature of the fermion determinant in this sector prohibits the use of established Monte Carlo techniques that utilize importance sampling. Whilst significant progress has been made in the low density, high temperature region, this remains a considerable challenge at mid to high density. At large chemical potential, QCD can be approximated using high density effective theory which is free from the sign problem at leading order. We investigate the implementation of this theory on the lattice in conjunction with existing re-weighting techniques.

description: The statistical properties of the carrier density profile of graphene in the ground state in the presence particle-particle interaction and random charged impurity in zero gate voltage has been recently obtained by Najafi \textit{et al.} (Phys. Rev E95, 032112 (2017)). The non-zero chemical potential ($μ$) in gated graphene has non-trivial effects on electron-hole puddles, since it generates mass in the Dirac action and destroys the scaling behaviors of the effective Thomas-Fermi-Dirac theory. We provide detailed analysis on the resulting spatially inhomogeneous system in the framework of the Thomas-Fermi-Dirac theory for the Gaussian (white noise) disorder potential. We show that, the chemical potential in this system as a random surface, destroys the self-similarity, and the charge field is non-Gaussian. We find that the two-body correlation functions are factorized to two terms: a pure function of the chemical potential and a pure function of the distance. The spatial dependence of these correlation functions is double-logarithmic, e.g. the two-point density correlation $D_2(r,μ)\propto μ^2\exp\left[-\left(-a_D\ln\ln r^{β_D}\right)^{α_D} \right]$ ($α_D=1.82$, $β_D=0.263$ and $a_D=0.955$). The Fourier power spectrum function behaves like $\ln(S(q))=-β_S^{-a_S}\left(\ln q \right)^{a_S}+2\ln μ$ ($a_S=3.0\pm 0.1$ and $β_S=2.08\pm 0.03$) in contrast to the ordinary Gaussian rough surfaces for which $a_S=1$ and $β_S=\frac{1}{2}(1+α)^{-1}$, ($α$ being the roughness exponent). The geometrical properties are however similar to the un-gated ($μ=0$) case, with the exponents that are reported in the text.

description: High critical-temperature superconductivity and large (colossal) magnetoresistances are two important electronic conducting phenomena found in transition metal oxides. High-Tc materials have applications such as superconducting magnets for MRI and NMR, and magnetoresistive materials may find use in magnetic sensors and spintronic devices. Here we report chemical doping studies of RuSr2(R2-xCex)Cu2O10-d ruthenocuprates which show that a single oxide system can be tuned between superconductivity at high hole dopings and varied magnetoresistive properties at low doping levels. A robust variation of negative magnetoresistance with hole concentration is found in the RuSr2R1.8-xY0.2CexCu2O10-d series, while RuSr2R1.1Ce0.9Cu2O10-d materials show an unprecedented crossover from negative to positive magnetoresistance with rare earth (R) ion radius.

description: Diabetes is a common chronic disease, characterized by defects in insulin action, secretion or both causing hyperglycemia. Diabetes can have serious long-term complications as it important to control blood glucose levels. Chemical and optical methods are used mainly in measuring glucose levels. Chemical methods require drawing blood several times a day which is uncomfortable for the patient. Optical sensor measurements are affected by physical and chemical parameters and environmental changes. In this study, we propose a method for detecting and quantifying blood glucose levels based on the nonlinear optical properties measurements using the z-scan technique. Gold, silver and gold/silver (core/shell) nanoparticles were synthesized using a wet chemistry where trisodium citrate was used as a reducing agent. A green synthesis method used curcumin and glucose as reducing agents. These nanoparticles are characterized by their plasmon absorbance band, and their shapes and sizes are confirmed by TEM. Glucose conjugated nanoparticles are either synthesized or mixed with glucose. The compositions of these conjugates were confirmed by TEM. Mie theory was used to determine the size of the nanoparticles. Nanoparticles conjugated with glucose were subjected to nonlinearities measurements using the z-scan technique. The z-scan experiments were preformed using 488 nm and 514 nm CW argon-ion laser with adjusting power of 15 – 30 mW to measure the nonlinear refractive index ( ). Z-scan measurements indicated that studied samples exhibited nonlinear optical properties. The experimental results show that the nonlinear refractive index was dependent on the concentration of glucose conjugated with metal particles. Thus, the nonlinear refractive index value of the given glucose sample may be used as a quantifying indicator.

description: Ganymede's atmosphere is produced by radiative interactions with its surface, sourced by the Sun and the Jovian plasma. The sputtered and thermally desorbed molecules are tracked in our Exospheric Global Model (EGM), a 3-D parallelized collisional model. This program was developed to reconstruct the formation of the upper atmosphere/exosphere of planetary bodies interacting with solar photon flux and magnetospheric and/or the solar wind plasmas. Here, we describe the spatial distribution of the H$_2$O and O$_2$ components of Ganymede's atmosphere, and their temporal variability along Ganymede's rotation around Jupiter. In particular, we show that Ganymede's O$_2$ atmosphere is characterized by time scales of the order of Ganymede's rotational period with Jupiter's gravity being a significant driver of the spatial distribution of the heaviest exospheric components. Both the sourcing and the Jovian gravity are needed to explain some of the characteristics of the observed aurora emissions. As an example, the O$_2$ exosphere should peak at the equator with systematic maximum at the dusk equator terminator. The sputtering rate of the H$_2$O exosphere should be maximum on the leading hemisphere because of the shape of the open/close field lines boundary and displays some significant variability with longitude.

description: Molecules that trace the high-density regions of the interstellar medium have been observed in (ultra-)luminous (far-)infrared galaxies, in order to initiate multiple-molecule multiple-transition studies to evaluate the physical and chemical environment of the nuclear medium and its response to the ongoing nuclear activity. The HCN(1-0), HNC(1-0), HCO+(1-0), CN(1-0) and CN(2-1), CO(2-1), and CS(3-2) transitions were observed in sources covering three decades of infrared luminosity including sources with known OH megamaser activity. The data for the molecules that trace the high-density regions have been augmented with data available in the literature. The integrated emissions of high-density tracer molecules show a strong relation to the far-infrared luminosity. Ratios of integrated line luminosities have been used for a first order diagnosis of the integrated molecular environment of the evolving nuclear starbursts. Diagnostic diagrams display significant differentiation among the sources that relate to initial conditions and the radiative excitation environment. Initial differentiation has been introduced between the FUV radiation field in photon-dominated-regions and the X-ray field in X-ray-dominated-regions. The galaxies displaying OH megamaser activity have line ratios typical of photon-dominated regions.

The impact of an educational intervention on Home Support Workers' ability to detect early pressure ulcer damage.
Creators: name: Mairead Patricia Clarke
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Background: Internationally, pressure ulcers remain a significant health care problem. This has prompted a growing interest in why pressure ulcer prevalence remains, and a desire to investigate why the prevention process continues to fail. Skin assessment is an essential component in pressure ulcer prevention. Evidence suggests that patients may not receive the correct level of care to maintain their skin integrity. Skin assessment is not the sole responsibility of the registered nurse. Home Support Workers are directly involved in patient care and they play a pivotal role in completing a comprehensive skin assessment. Therefore, all health care workers completing a comprehensive skin assessment require education in order to fulfil this role. Aim: To investigate the impact of an educational intervention on Community Home Support Workers’ ability to detect early pressure ulcer damage. Method: A repeated measure design was employed to quantify the effectiveness of an educational intervention, consisting of one pre-test and two post-tests. This was followed by a workshop tasked with reflecting on the educational intervention. Findings: Home Support Workers were asked to accurately classify 20 photographs of varying stages of skin severity at each measuring point. At the baseline, 58% of the photographs were classified correctly. In the post-test 1, the results were lower, with 55% of the photographs being correctly classified. In the post-test 2, correct classification increased to 58%, e.g. back to the original baseline scores. There was a moderate negative relationship between pre-training and post-test 2 scores (r=-.44; n=27; p=0.02). To capture the participants’ issues following the educational, words used by them were recorded, as they represented the terms and language that the participants placed on their main concerns and affirmations. Conclusion: The educational intervention has been shown not to have a statistical significant positive effect on Home Support Workers’ ability to detect early pressure ulcer damage. There was a negative correlation between pre-training and post-test 2 scores. The workshop group findings exposed the challenges which exist relating to difficulties understanding relevant theoretical health concepts. These issues are fundamentally related to a low health literacy among the study participants.

Although in most cases I prefer not to enter into the technical aspects of how implementing such methods, more details will be furnishes about the description of galaxy clustering in terms of fractal concepts. Despite recent claims for a Universe, which behaves like a fractal at arbitrarily large scales, I will show that the fractal language can be usefully employed to disprove this picture. The emerging scenario is that of a Universe, which behaves like a self-similar structure at small scales, where fractality is dynamically generated by non-linear gravitational clustering, while preserving large-scale homogeneity. Nevertheless, even at scales $\magcir 10\hm$, where gravity still acts linearly, the distribution of galaxy clusters shows remarkable scale-invariant features, which could give precise hints about the initial conditions for the evolution of the large-scale structure of the Universe.

description: We report on the polarization properties of two fast radio bursts (FRBs): 151230 and 160102 discovered in the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB) at the Parkes radio telescope. FRB 151230 is observed to be 6 $\pm$ 11% circularly polarized and 35 $\pm$ 13 % linearly polarized with a rotation measure (RM) consistent with zero. Conversely, FRB 160102 is observed to have a circular polarization fraction of 30 $\pm$ 11 %, linear polarization fraction of 84 $\pm$ 15 % for RM = -221(6) rad m$^{-2}$ and the highest measured DM (2596.1 $\pm$ 0.3 pc cm$^{-3}$) for an FRB to date. We examine possible progenitor models for FRB 160102 in extragalactic, non-cosmological and cosmological scenarios. After accounting for the Galactic foreground contribution, we estimate the intrinsic RM to be -256(9) rad m$^{-2}$ in the low-redshift case and $\sim 2.4 \times 10^{2}$ rad m$^{-2}$ in the high-redshift case. We assess the relative likeliness of these scenarios and how each can be tested. We also place constraints on the scattering measure and study the impact of scattering on the signal's polarization position angle.

On Quantum Deformation of the Schwarzschild Solution

description: We consider the deformation of the Schwarzschild solution in general relativity due to spherically symmetric quantum fluctuations of the metric and the matter fields. In this case, the 4D theory of gravity with Einstein action reduces to the effective two-dimensional dilaton gravity. We have found that the Schwarzschild singularity at $r=0$ is shifted to the finite radius $r_{min} \sim r_{Pl}$, where the scalar curvature is finite, so that the space-time looks regular and consists of two asymptotically flat sheets glued at the hypersurface of constant radius.

LDPC codes in the McEliece cryptosystem: attacks and countermeasures

description: The McEliece cryptosystem is a public-key cryptosystem based on coding theory that has successfully resisted cryptanalysis for thirty years. The original version, based on Goppa codes, is able to guarantee a high level of security, and is faster than competing solutions, like RSA. Despite this, it has been rarely considered in practical applications, due to two major drawbacks: i) large size of the public key and ii) low transmission rate. Low-Density Parity-Check (LDPC) codes are state-of-art forward error correcting codes that permit to approach the Shannon limit while ensuring limited complexity. Quasi-Cyclic (QC) LDPC codes are a particular class of LDPC codes, able to join low complexity encoding of QC codes with high-performing and low-complexity decoding of LDPC codes. In a previous work it has been proposed to adopt a particular family of QC-LDPC codes in the McEliece cryptosystem to reduce the key size and increase the transmission rate. Recently, however, new attacks have been found that are able to exploit a flaw in the transformation from the private key to the public one. Such attacks can be effectively countered by changing the form of some constituent matrices, without altering the system parameters. This work gives an overview of the QC-LDPC codes-based McEliece cryptosystem and its cryptanalysis. Two recent versions are considered, and their ability to counter all the currently known attacks is discussed. A third version able to reach a higher security level is also proposed. Finally, it is shown that the new QC-LDPC codes-based cryptosystem scales favorably with the key length.

description: Introduction: Falls are the commonest reason why an older person presents to the Emergency Department (ED) in Ireland and can account for 20-40% of attendances (Aminzadeh and Dalziel 2002). As the population ages it is anticipated that the incidence of falls will increase (Barrett et al, 2011). A profile of the elderly faller could identify the healthcare services in which this population relies on.  Aims and Objectives: The aims of this study were to profile a sample of elderly fallers attending the ED of an Irish hospital. The objectives of the study were to examine prevalence and circumstances of these falls, to describe the socio-demographic and health profile of these patients and to document the healthcare utilisation among the sample. Methods: This was a cross-sectional, observational study in which 93 participants were recruited at discharge from an Irish ED. A demographic profile along with healthcare utilisation was determined from the ED chart and Patient Administration System (PAS). Participants completed a questionnaire to determine the presence of frailty, a falls profile, and level of social support available. Results: The mean age of participants was 76.5 years of age. Recurrent falls were noted in 46% of the sample. Polypharmacy was identified in 43 (55.8%) participants. Twenty (21.5%) participants belonged to a vulnerable social network type. Just over half (52.7%) of participants were identified at risk of decline. Seventeen (18.3%) of the 93 participants had a previous visit to the ED in the previous six months. High healthcare follow up was noted with 89.2% of participants referred to either community services or out-patient appointments. Conclusions and implications: This study described an elderly population at risk of functional decline with high healthcare needs. The findings of this study could form the basis of the development of a standardised frailty screening and intervention programme for elderly fallers attending the ED and highlights missed opportunities for frailty management.

description: We study the Rarita-Schwinger operator on compact Riemannian spin manifolds. In particular, we find examples of compact Einstein manifolds with positive scalar curvature where the Rarita-Schwinger operator has a non-trivial kernel. For positive quaternion Kähler manifolds and symmetric spaces with spin structure we give a complete classification of manifolds admitting Rarita-Schwinger fields. In the case of Calabi-Yau, hyperkähler, $G_2$ and Spin(7) manifolds we find an identification of the kernel of the Rarita-Schwinger operator with certain spaces of harmonic forms. We also give a classification of compact irreducible spin manifolds admitting parallel Rarita-Schwinger fields.

description: We present results from a leptonic emission code that models the spectral energy distribution of a pulsar wind nebula by solving a Fokker-Planck-type transport equation and calculating inverse Compton and synchrotron emissivities. We have created this time-dependent, multi-zone model to investigate changes in the particle spectrum as they traverse the pulsar wind nebula, by considering a time and spatially-dependent B-field, spatially-dependent bulk particle speed implying convection and adiabatic losses, diffusion, as well as radiative losses. Our code predicts the radiation spectrum at different positions in the nebula, yielding the surface brightness versus radius and the nebular size as function of energy. We compare our new model against more basic models using the observed spectrum of pulsar wind nebula G0.9+0.1, incorporating data from H.E.S.S. as well as radio and X-ray experiments. We show that simultaneously fitting the spectral energy distribution and the energy-dependent source size leads to more stringent constraints on several model parameters.

The PIPc study: Development and validation of indicators of potentially inappropriate prescribing in children (PIPc) in primary care
Creators: name: Barry, Emma
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Background: There is limited evidence regarding the quality of prescribing for children in primary care. Several prescribing criteria (indicators) have been developed to assess the appropriateness of prescribing in older and middle aged adults but few are relevant to children. This thesis outlines the development of a set of prescribing indicators to be applied to be applied to the Primary Care Reimbursement Database (PCRS) to determine the prevalence of potentially inappropriate prescribing (PIP) in children in primary care settings. Methods: Two round Delphi consensus method: A literature search was conducted to identify published indicators for children (< 16 years). A Project Steering Group reviewed the suitability of the indicators. These criteria underwent a two round Delphi process using an expert panel consisting of general practitioners, pharmacists, paediatricians and clinical pharmacologists from the Republic of Ireland and the United Kingdom. Using a web based questionnaire, 15 panellists were asked to indicate their level of agreement with each indicator via a five point Likert scale to assess applicability to children in the absence of clinical information. Criteria were accepted or rejected or revised based on the panel’s level of agreement using the median response/interquartile range and additional comments. The final set of indicators was applied to the PCRS database for 2014 to determine the prevalence of PIP in children. The association of PIPc and gender were examined. Costs of PIP were calculated Results: The final list consisted of 12 indicators categorized by respiratory system (n=6), gastrointestinal system (n=2), neurological system (n=2) and dermatological system (n=2). The most common commission of PIPc was the prescribing of carbocisteine to children (32.7/1000 GMS children). The most common omission of appropriate prescribing was the failure to prescribe a spacer device at least annually for children < 12 years who used a pressurised metered dose inhaler (70% of eligible children).The relative risk of PIPc in males compared to females was statistically significant by indicators of omission (RR 1.3; 95% CI 1.02-1.66) but not by indicators of commission (RR 1.03; 95% CI 0.65-1.62).The costs not incurred or saved due to omissions of appropriate prescribing (€678,816.30) far exceeded the costs incurred by commissions of PIPc in 2014. (€129,255.04) 15 Conclusions: The PIPc indicators are the first set of prescribing criteria developed for use in children in primary care. The prevalence of PIP in GMS eligible children was found to be low.

description: Real world networks have, for a long time, been modelled by scale-free networks, which have many sparsely connected nodes and a few highly connected ones (the hubs). However, both in society and in biology, a new structure must be acknowledged, the fractional networks. These networks are characterized by the existence of very many long-range connections, display superdiffusion, Lévy flights and robustness properties different from the scale-free networks.
