description: Background: Advanced glycation end products (AGEs) are a group of molecules formed through non-enzymatic reactions. These compounds are associated to several age-related diseases, including sarcopenia and osteoporosis. Objective: To investigate the relationships between AGEs, osteoporosis, and sarcopenia in community-dwelling older adults in China.Materials and Methods: This cross-sectional study included 1991 older adults aged ≥ 65 years from Shanghai, China. AGE levels were measured by AGE ReaderTM device. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry, and osteoporosis was diagnosed based on a T score less than -2.5. Sarcopenia was defined as a loss of muscle mass plus loss of muscle strength and/or reduced physical performance. Presarcopenia was defined as a low muscle mass with normal muscle strength and normal physical performance. The ‘RMediation’ package and Iacobacci's method were utilized to assess the mediation effect. Results: Among the 1991 participants (854 men) with a mean age of 72.37 ± 5.90 years, the prevalence of sarcopenia was 18.5% (n=368), and that of osteoporosis was 40.5% (n=807). The mean AGE value was 1.67±0.44 arbitrary units (AU). Compared to the lowest AGEs quartile (Q1), the highest AGE quartile (Q4) showed a significant association with sarcopenia (OR 2.42, 95% CI [1.60, 3.66]) (P for trend <0.001), but not with presarcopenia. Per standard deviation(SD) increase in AGE was associated with higher odds of sarcopenia(OR 1.44, 95% CI [1.26, 1.66]). Additionally, in the mediation analysis, when AGEs were treated as a continuous variable (the size of the mediation effect is denoted by Za*Zb=18.81, 95% CI [8.07, 32.32]—the 95% CI does not contain zero, representing a significant mediating effect) or a categorical variable (the size of the mediating effect is expressed as Zmediation=3.01>1.96, which represents a significant mediating effect ), osteoporosis played a partial mediating role in the association between AGEs and sarcopenia. Conclusions: This study revealed an association between AGEs and sarcopenia, but not presarcopenia, among community-dwelling older adults in China. Osteoporosis was identified as a mediating factor in the link between AGEs and sarcopenia.

description: Dynamos operating in the interiors of rapidly rotating planets and low-mass stars might belong to a similar category where rotation plays a vital role. We quantify this similarity using scaling laws. We analyse direct numerical simulations of Boussinesq and anelastic spherical shell dynamos. These dynamos represent simplified models which span from Earth-like planets to rapidly rotating low-mass stars. We find that magnetic field and velocity in these dynamos are related to the available buoyancy power via a simple power law which holds over wide variety of control parameters.

description: The purpose of this paper is to evaluate the post-operative Magnetic Resonance Perfusion (MRP) scans of patients undergoing carotid endarterectomy (CEA), using a novel image-analysis algorithm, to determine if post-operative neurocognitive decline is associated with cerebral blood flow changes. CEA procedure reduces the risk of stroke in appropriately selected patients with significant carotid artery stenosis. However, 25% of patients experience subtle cognitive deficits after CEA compared to a control group. It was hypothesized that abnormalities in cerebral blood flow (CBF) are responsible for these cognitive deficits. A novel algorithm for analyzing MRperfusion (MRP) scans to identify and quantify the amount of CBF asymmetry in each hemisphere was developed and to quantify the degree of relative difference between three corresponding vascular regions in the ipsilateral and contralateral hemispheres, the Relative Difference Map (RDM). Patients undergoing CEA and spine surgery (controls) were examined preoperatively, and one day postoperatively with a battery of neuropsychometric (NPM) tests, and labeled “injured” patients with significant cognitive deficits, and “normal” if they demonstrated no decline in neurocognitive function. There are apparently significant RDM differences with MRP scans between the two hemispheres in patients with cognitive deficits which can be used to guide expert reviews of the imagery. The proposed methodology aids in the analysis of MRP parameters in patients with cognitive impairment.

description: We compute self-consistently the Josephson current in a superconductor-antiferromagnet-superconductor junction using a lattice model, focusing on $0-π$ transitions occurring when the width of the antiferromagnetic region changes from an even to an odd number of lattice sites. Previous studies predicted $0-π$ transitions when alternating between an even and an odd number of sites for sufficiently strong antiferromagnetic order. We study numerically the magnitude of the threshold value for this to occur, and also explain the physics behind its existence in terms of the phase-shifts picked up by the quasiparticles constituting the supercurrent in the antiferromagnet. Moreover, we show that this threshold value allows for \textit{pressure-induced $0-π$ transitions} by destroying the antiferromagnetic nesting properties of the Fermi surface, a phenomenon which has no counterpart in ferromagnetic Josephson junctions, {offering a new way to tune the quantum ground state of a Josephson junction without the need of multiple samples.

description: We extend the formulation of the spin wave theory for the Kondo lattice model, which was mainly used for the ferromagnetic metallic state, to general magnetic orders including complex noncollinear and noncoplanar orders. The 1/S expansion is reformulated in the matrix form depending on the size of the magnetic unit cell. The noncollinearity and noncoplanarity of the localized moments are properly taken into account by the matrix elements of the para-unitary matrix used in the diagonalization of the Bogoliubov-de Gennes type Hamiltonian for magnons. We apply the formulation within the linear spin wave approximation to a typical noncollinear case, the $120^{\circ}$ N{é}el order on a triangular lattice at half filling. We calculate the magnon excitation spectrum and the quantum correction to the magnitude of ordered moments as functions of the strength of the Hund's-rule coupling, $J_{\rm H}/t$. We find that the magnon excitation shows softening at $J_{\rm H}/t \simeq 2.9$, which indicates that the $120^{\circ}$ order is destabilized for smaller $J_{\rm H}/t$. On the other hand, we show that the $120^{\circ}$ order is stable in the entire range of $J_{\rm H}/t \gtrsim 2.9$, and, in the limit of $J_{\rm H}/t \to \infty$, the form of the spin wave spectrum approaches that for the antiferromagnetic Heisenberg model, while the bandwidth is proportional to $t^2/J_{\rm H}$. The reduction of the ordered moment is smaller than that for the spin-only model, except in the vicinity of the softening.

description: Im wissenschaftlichen Publizieren vollziehen sich umfangreiche Veränderungen getrieben durch Möglichkeiten der Digitalisierung und Open Access (OA). Gleichzeitig wächst der Einfluss von Großverlagen auf das Ökosystem der Wissenschaft, durch die Monopolstrukturen im Publikationsmarkt sowie Akquise/ Integration wissenschaftsnaher Tools und neuer, auf Daten, Analysen und KI basierender Geschäftsmodelle. Während diese Verlage hohe Gewinnspannen erwirtschaften, droht der Wissenschaft der zunehmende Verlust der Souveränität über ihre (eigenen) Werkzeuge, Daten sowie Publikationskanäle.

Von Wissenschaft getragene und geführte Publikationsinfrastrukturen und Diamond OA bieten vielversprechenden Möglichkeiten zum Gegensteuern: Zeitschriften und andere Publikationsformen, die unter der Verantwortung einer oder mehrerer wissenschaftlicher Einrichtungen betrieben werden, sind wichtige Elemente für die (Wieder-)Erlangung wissenschaftlicher Souveränität. Insbesondere wenn durch breite Einbettung dieser Publikationsinfrastrukturen in die Open-Science-Landschaft ein nachhaltiger Betrieb möglich wird.

Die Helmholtz-Gemeinschaft, Deutschlands größte außeruniversitäre Forschungsorganisation, fördert unter Federführung seines Open Science Office einen Diskussionsprozess, um die Weiterentwicklung der Open-Access-Transformation und eine Hinwendung zu wissenschaftsgetragenen Publikationsinfrastrukturen und zum wissenschaftsgeleiteten OA-Publizieren zu unterstützen. In einem ersten Schritt wurde das Diskussionspapier “Wissenschaftliches Publizieren bei Helmholtz: Status Quo, Szenarien für Scholar-led Publizieren - ein Diskussionspapier” [1] veröffentlicht, dass das Helmholtz Open Science Office gemeinsam mit der Task Group Open Access Transformation der Arbeitskreise Open Science und Bibliothek- und Informationsmanagement entwickelt hat. Damit in Verbindung stehend wird aktuell an der Neuformulierung eines bis dato internen Memorandums für die Open-Access-Transformation bei der Helmholtz-Gemeinschaft gearbeitet, welches Leitlinien u. a. für transformative Verträge geben soll [2].

Der Vortrag präsentierte das Diskussionspapier und die Relevanz der wesentlichen Akteur:innengruppen (wie wissenschaftlichen Gemeinschaften, Dienstleister, Infrastruktureinrichtungen/ Bibliotheken) und deren notwendige Zusammenarbeit innerhalb einer Forschungsorganisation wie Helmholtz. Darüber hinaus wurde ein Einblick in das Memorandum und seiner wichtigsten Eckpunkte und Leitplanken gegeben.

description: Geometric algorithms for linear independent component analysis (ICA) have recently received some attention due to their pictorial description and their relative ease of implementation. The geometric approach to ICA was proposed first by Puntonet and Prieto (1995). We will reconsider geometric ICA in a theoretic framework showing that fixed points of geometric ICA fulfill a geometric convergence condition (GCC), which the mixed images of the unit vectors satisfy too. This leads to a conjecture claiming that in the nongaussian unimodal symmetric case, there is only one stable fixed point, implying the uniqueness of geometric ICA after convergence. Guided by the principles of ordinary geometric ICA, we then present a new approach to linear geometric ICA based on histograms observing a considerable improvement in separation quality of different distributions and a sizable reduction in computational cost, by a factor of 100, compared to the ordinary geometric approach. Furthermore, we explore the accuracy of the algorithm depending on the number of samples and the choice of the mixing matrix, and compare geometric algorithms with classical ICA algorithms, namely, Extended Infomax and FastICA. Finally, we discuss the problem of high-dimensional data sets within the realm of geometrical ICA algorithms.

title: Advancements in image sensor technology for soft X-ray spectroscopy in space: CIS detectors for the Auroral X-ray Imaging Spectrometer
Creators: name: Jones, Lawrence S.
Publisher: name: The Open University
Year: 2023

description: Soft X-rays with energies below 2 keV are of tremendous scientific utility for planetary science but are particularly challenging to detect and analyse due to their low energies and short attenuation lengths. Solid state image sensor based X-ray detectors, derived from charge coupled devices (CCDs) and CMOS image sensors (CISs), have the potential to capture information about a soft X-ray flux in the time, spatial, and energy domains, and so are a potent scientific tool. Developing X-ray detector technology is enabling the application of soft X-ray imaging spectrometers in ever more demanding environments, with the current state of the art CIS promising the potential for high temperature, Fano-limited, performance. This thesis investigates the use of solid state image sensors for soft- X-ray imaging spectroscopy in space-based applications. Specifically: an evaluation of the radiation damage experienced by the swept charge devices (SCDs) of the Chandrayaan-2 Large Area Soft X-ray Spectrometer (CLASS) which was shown to be within expectations and consistent with the requirements for continued science operation; and a study of X-ray detectors for the Auroral X-ray Imaging Spectrometer (AXIS) instrument aboard the Disturbed and quiet-time Ionosphere System at High Altitudes (DISHA) mission, resulting in the adoption of a novel CIS X-ray detector into the instrument design. The AXIS study has found that the newly developed CISs are now equal to their CCD counterparts in some soft X-ray imaging spectroscopy applications, potentially enabling new science targets to be pursued. The successful recommendation to change the AXIS instrument X-ray detector from the more mature EMCCD CCD201-20 of the baseline design, to the less mature but better performing CIS221-X and its derivatives represents a milestone in the development of CIS X-ray detector technology.

description: A Free Electron Laser (FEL) facility utilizing a recirculated Superconducting Radio Frequency (SRF) linear accelerator (linac) provides the opportunity to achieve about five times greater photon energy than an unrecirculated linac of similar cost. > A 4 GeV SRF, cw, electron linac can be used to drive an FEL producing 5 keV photons. The SLAC National Accelerator Laboratory, a Department of Energy (DOE) Basic Energy Sciences (BES) laboratory, proposes to utilize a 4 GeV unrecirculated, SRF, linac in a segment of existing linac tunnel. > For an initial investment similar to that of the proposed SLAC strategy, a recirculated SRF linac system could deliver the 4 GeV electrons for photon energies of 5 keV and provide an upgrade path to photon energies of 25 keV. > Further support amounting to about a third of the initial investment would provide upgrade funds for additional SRF linac and cryogenic capacity sufficient to provide electron energies appropriate for 25 keV photons matching the European XFEL.

description: In a multi-agent system, agents coordinate to achieve global tasks through local communications. Coordination usually requires sufficient information flow, which is usually depicted by the connectivity of the communication network. In a networked system, removal of some agents may cause a disconnection. In order to maintain connectivity in agent removal, one can design a robust network topology that tolerates a finite number of agent losses, and/or develop a control strategy that recovers connectivity. This paper proposes a decentralized control scheme based on a sequence of replacements, each of which occurs between an agent and one of its immediate neighbors. The replacements always end with an agent, whose relocation does not cause a disconnection. We show that such an agent can be reached by a local rule utilizing only some local information available in agents' immediate neighborhoods. As such, the proposed message passing strategy guarantees the connectivity maintenance in arbitrary agent removal. Furthermore, we significantly improve the optimality of the proposed scheme by incorporating $δ$-criticality (i.e. the criticality of an agent in its $δ$-neighborhood).

description: PRISMA is a demonstration mission for formation-flying and on-orbit-servicing critical technologies that involves two spacecraft launched in low Earth orbit in June 2010 and still in operation. Funded by the Swedish National Space Board, PRISMA mission has been developed by OHB Sweden with important contributions from the German Aerospace Centre (DLR/GSOC), the French Space Agency (CNES), and the Technical University of Denmark (DTU). The paper focuses on the last CNES experiment achieved in September 2012 that was devoted to the preparation of future astrometry missions illustrated by the NEAT and microNEAT mission concepts. The experiment consisted in performing the type of formation maneuvers required to point the two-satellite axis to a celestial target and maintain it fixed during the observation period. Achieving inertial pointing for a LEO formation represented a new challenge given the numerous constraints from propellant usage to star tracker blinding. The paper presents the experiment objectives in relation with the NEAT/microNEAT mission concept, describes its main design features along with the guidance and control algorithms evolutions and discusses the results in terms of performances achieved during the two rehearsals

description: In many Hamiltonian systems, propagation of steadily travelling solitons or kinks is prohibited because of resonances with linear excitations. We show that Hamiltonian systems with resonances may admit an infinite number of travelling solitons or kinks if the closest to the real axis singularities in the complex upper half-plane of limiting asymptotic solution are of the form $z_\pm=\pmα+iβ$, $α\ne 0$. This quite a general statement is illustrated by examples of the fifth-order Korteweg--de Vries-type equation, the discrete cubic-quintic Klein--Gordon equation, and the nonlocal double sine--Gordon equations.

description: We study Landau-Zener transitions between two states with the addition of a shared discretized continuum. The continuum allows for population decay from the initial state as well as indirect transitions between the two states. The probability of nonadiabatic transition in this multichannel model preserves the standard Landau-Zener functional form except for a shift in the usual exponential factor, reflecting population transfer into the continuum. We provide an intuitive explanation for this behavior assuming independent individual transitions between pairs of states. In contrast, the probability of survival in the ground state at long time shows a novel, non-monotonic, functional form, with an oscillatory behavior in the sweep rate at low sweep rate values. We contrast the behavior of this open-multistate model to other generalized Landau-Zener models incorporating an environment: the stochastic Landau-Zener model and the dissipative case, where energy dissipation and thermal excitations affect the adiabatic region. Finally, we present evidence that the continuum of states may act to shield the two-state Landau-Zener transition probability from the effect of noise.

description: Spin electromagnetic fields driven by the Rashba spin-orbit interaction, or Rashba-induced spin Berry's phase, in ferromagnetic metals is theoretically studied based on the Keldysh Green's function method. Considering a limit of strong sd coupling without spin relaxation (adiabatic limit), the spin electric and magnetic fields are determined by calculating transport properties. The spin electromagnetic fields turn out to be expressed in terms of a Rashba-induced effective vector potential, and thus they satisfy the Maxwell's equation. In contrast to the conventional spin Berry's phase, the Rashba-induced one is linear in the gradient of magnetization profile, and thus can be extremely large even for slowly varying structures. We show that the Rashba-induced spin Berry's phase exerts the Lorentz force on spin resulting in a giant spin Hall effect in magnetic thin films in the presence of magnetization structures. Rashba-induced spin magnetic field would be useful to distinguish between topologically equivalent magnetic structures.

description: We propose a framework for multi-modality brain registration methods using symmetry plane as the principal feature for geometric matching. By bringing the symmetry plane of two rigid objects into coincidence, we can potentially match two objects approximately ifthere is no apparent elastic distortion. We illustrate this concept using Visible Human dataset, that includes color cryosection, and radiological data, from which we extract 3D mesh models of skin, brain and skull, and aligned them into nested bodies. Each model was generated with different spatial orientation and resolution, and their alignment, was guided by the underlying anatomical relationships in the head region, and a requirement, by an application that the meshes didn't intersect. After alignment of the symmetry planes, obtained for each mesh using spatial affine transformations, the further geometric adjustment, to achieve complete registration of the nested models, is confined within a 2D plane (i.e. the symmetry plane). This simple method of registration of mesh anatomical models, has a potential to significantly reduce the degrees of freedom in various 3D brain registration applications. It can be also treated as a pre-registration operation before applying other registration methods.

description: How vulnerable are we to misinformation on social media? To address this question, this study examines not only how well (or poorly) individuals discern true and false news on social media, but also how contextual factors in news presentation and individual’s cognitive and motivational tendencies might shape the patterns of their beliefs in and likelihood to engage online news. We conducted an online survey experiment on a sample of Chinese social media users recruited from a national panel (N = 481). The results show that, first, people generally perceived social media news as accurate and were better at correctly identifying truthful news than false news, revealing both a truth bias and a veracity effect. Second, social endorsement cue and news content slant could affect how individuals judge the veracity of a news post and engage it online. Third, evidence was mixed on how individuals’ deliberative thinking propensity and epistemic motive operated. While our primary goal is to present evidence from a non-Western society to shed lights on the psychology of false news on social media, we also strive toward teasing out some implications specific to the China context.

description: For Hurricane Florence, we present the first advance forecasted attribution statements about the human influence on a tropical cyclone. We find that rainfall will be significantly increased by over 50% in the heaviest precipitating parts of the storm. This increase is substantially larger than expected from thermodynamic considerations alone. We further find that the storm will remain at a high category on the Saffir-Simpson scale for a longer duration and that the storm is approximately 80 km in diameter larger at landfall because of the human interference in the climate system.

description: Instagram’s sensitive-content screens seek to minimize engagement with negative content by blurring sensitive images and providing a warning. However, the very design of sensitive-content screens may elicit uncertainty/curiosity and prompt information-seeking behaviors: congruent with the information-gap hypothesis. To test this idea experimentally, we presented participants with screened negative images accompanied by a brief, detailed, or no content description, during a simulated Instagram task. Participants viewed screens one at a time and uncovered at their discretion. In line with our predictions, people uncovered screens irrespective of description type, but did so most often with no description. Most participants indicated that knowing what the sensitive content contained bolstered their ability to make an informed decision. These results have implications; information provided alongside sensitive-content screens can influence engagement and therefore should be considered as part of sensitive-content guidelines.

description: Single MeV electrons subjected in vacuum to single high-intensity quadratically-chirped laser pulses are shown to gain multi-GeV energies. The laser pulses are modeled by finite-duration trapezoidal and $\cos^2$ pulse-shapes and the equations of motion are solved numerically. It is found that, typically, the maximum energy gain from interaction with a quadratic chirp is about half of what would be gained from a linear chirp.

Subjects: subject: 530 Physik

description: Dynamical tunneling between symmetry related invariant tori is studied in the near-integrable regime. Using the kicked Harper model as an illustration, we show that the exponential decay of the wave functions in the classically forbidden region is modified due to coupling processes that are mediated by classical resonances. This mechanism leads to a substantial deviation of the splitting between quasidegenerate eigenvalues from the purely exponential decrease with 1/ {\it [h-bar] } obtained for the integrable system. A simple semiclassical framework, which takes into account the effect of the resonance substructure on the invariant tori, allows one to quantitatively reproduce the behavior of the eigenvalue splittings.
Kochen-Specker Sets with a Mixture of 16 Rank-1 and 14 Rank-2 Projectors for a Three-Qubit System

description: Kochen-Specker (KS) theorem denies the possibility for the noncontextual hidden variable theories to reproduce the predictions of quantum mechanics. A set of projection operators (projectors) and bases used to show the impossibility of noncontextual definite values assignment is named as the KS set. Since one KS set with a mixture of 16 rank-1 projectors and 14 rank-2 projectors proposed in 1995 [Kernaghan M and Peres A 1995 Phys. Lett.\ A \textbf{198} 1] for a three-qubit system, there are plenty of the same type KS sets and we propose a systematic way to produce them. We also propose a probabilistic state-dependent proof of the KS theorem that mainly focuses on the values assignment for all the rank-2 projectors.

description: We explain how specific dynamical properties give rise to the limit distribution of sums of deterministic variables at the transition to chaos via the period-doubling route. We study the sums of successive positions generated by an ensemble of initial conditions uniformly distributed in the entire phase space of a unimodal map as represented by the logistic map. We find that these sums acquire their salient, multiscale, features from the repellor preimage structure that dominates the dynamics toward the attractors along the period-doubling cascade. And we explain how these properties transmit from the sums to their distribution. Specifically, we show how the stationary distribution of sums of positions at the Feigebaum point is built up from those associated with the supercycle attractors forming a hierarchical structure with multifractal and discrete scale invariance properties.

description: Let k be a field. A "field generator" is a polynomial F in k[X,Y] satisfying k(F,G) = k(X,Y) for some G in k(X,Y). If G can be chosen in k[X,Y], we call F a "good field generator"; otherwise, F is a "bad field generator". These notions were first studied by Abhyankar, Jan and Russell in the 1970s. The present paper introduces and studies the notions of "very good" and "very bad" field generators. We give theoretical results as well as new examples of bad and very bad field generators.

description: Haptic technology, or haptics, is a tactile feedback technology which takes advantage of a user's sense of touch by applying forces, vibrations, and/or motions upon the user. This mechanical stimulation may be used to assist in the creation of virtual objects (objects existing only in a computer simulation), for control of such virtual objects, and for the enhancement of the remote control of machines and devices. It has been described as for the sense of touch what computer graphics does for vision. Although haptic devices are capable of measuring bulk or reactive forces that are applied by the user, it should not be confused with touch or tactile sensors that measure the pressure or force exerted by the user to the interface.

description: Multiple scattering is a process in which a particle is repeatedly deflected by other particles. In an overwhelming majority of cases, the ensuing random walk can successfully be described through Gaussian, or normal, statistics. However, like a (growing) number of other apparently inofensive systems, diffusion of light in dilute atomic vapours eludes this familiar interpretation, exhibiting a superdiffusive behavior. As opposed to normal diffusion, whereby the particle executes steps in random directions but with lengths slightly varying around an average value (like a drunkard whose next move is unpredictable but certain to within a few tens of centimeters), superdiffusion is characterized by sudden abnormally long steps (Lévy flights) interrupting sequences of apparently regular jumps which, although very rare, determine the whole dynamics of the system. The formal statistics tools to describe superdiffusion already exist and rely on stable, well understood distributions. As scientists become aware of, and more familiar with, this non-orthodox possibility of interpretation of random phenomena, new systems are discovered or re-interpreted as following Lévy statistics. Propagation of light in resonant atomic vapours is one of these systems that have been studied for decades and have only recently been shown to be the scene of Lévy flights.

description: We apply the asymptotic iteration method (AIM) to obtain the solutions of Schrodinger equation in the presence of Poschl-Teller (PT) potential. We also obtain the solutions of Dirac equation for the same potential under the condition of spin and pseudospin (p-spin) symmetries. We show that in the nonrelativistic limits, the solution of Dirac system converges to that of Schrodinger system. Rotational-Vibrational energy eigenvalues of some diatomic molecules are calculated. Some special cases of interest are studied such as s-wave case, reflectionless-type potential and symmetric hyperbolic PT potential. Furthermore, we present a high temperature partition function in order to study the behavior of the thermodynamic functions such as the vibrational mean energy U, specific heat C, free energy F and entropy S.

Evaluating the effectiveness of the Minnesota Living with Heart Failure Questionnaire in initiating goals of care conversations

description: The DNP project focused on evaluating the effectiveness of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) in initiating goals of care discussions between heart failure (HF) patients 65 and older and their healthcare providers. Research suggests that these discussions should begin early in the diagnosis of HF but often occur later in the course of the disease, drastically impacting the patient’s quality of life.The project was a quality improvement project which utilized a pre-test/post-test design. Recruitment involved using flyers distributed in an acute-care hospital through various channels. Interactions with participants occurred through mail, e-mail, and telephone. The data was analyzed using Likert-type scale from MLHFQ and parametric tests used.16 participants were enrolled in the project. The average scores of MLHFQ before GoC discussions (pretest) was 40.88.The average scores of MLHFQ 6-weeks after GoC discussions was 33.44. The average decline in scores between pretest and posttest was 7.44 (or 7.09%) indicating an improvement in the participants quality of life after having the goals of care discussions. The p-value was .01, indicating statistically significant difference between pretest and posttest. Five participants scored 60 or higher and subsequently underwent palliative care discussions. The project highlighted the gap between clinical practice guidelines and current practice. Through utilizing a tool such as the MLHFQ, patients can become more educated on disease process. Furthermore, the tool can be an indicator for timely palliative care referrals. The MLHFQ can assist in providing education, decreasing costly treatment associated with exacerbations. The goals of care discussions can strengthen patient-provider relationship and help to reduce hospital readmissions. Patient education has the ability to decrease likelihood of disease exacerbations.
