description: Background: Many acute coronary syndrome (ACS; myocardial infarction and unstable angina) patients are rehospitalized within 30 days of discharge, and recent US health policy initiatives have tied hospital Medicare reimbursement to 30-day readmission rates. Patient-perceived psychological stress is thought to impact prognosis after ACS. A recently offered “posthospital syndrome” model of 30-day readmissions posits that the stress level at the time of the index hospitalization itself may increase 30-day risk for readmission in ACS patients. We tested whether self-reported stress in the days surrounding the ACS hospitalization was associated with increased risk for readmission within 30 days. Methods: A mean of 8.5 days after discharge, 342 consecutively hospitalized ACS patients reported on how often they felt stress during the past two weeks. Readmission within 30 days of hospital discharge for any cause was determined by follow-up telephone calls to patients and confirmed by hospital records. Results: Overall, 40 (11.7%) participants were readmitted within 30 days, and 22 (6.4%) reported high stress. Readmission within 30 days was more common in patients with high stress (5 admissions, 23%) than in patients with low stress (35 admissions, 11%). After adjustment for demographic and clinical factors, as well as depression, high stress was associated with a 3-fold increased risk of 30-day readmission (HR = 3.21, 95% CI = 1.13, 9.10). Conclusions: Previous research has shown that stress in the days surrounding a hospitalization can mark long-term cardiovascular risk, but this is the first study to test a hypothesis of the posthospital syndrome model of early readmission. Further research is needed to confirm the association between stress and readmission risk, and to identify the processes of hospitalization that could be modified to both reduce the stress experienced and that would also be effective for reducing readmissions.

description: Posttraumatic stress disorder (PTSD) is an anxiety disorder initiated by exposure to a traumatic event and characterized by intrusive thoughts about the event, attempts to avoid reminders of the event, and physiological hyperarousal. In a number of large prospective observational studies, PTSD has been associated with incident cardiovascular disease (CVD) and mortality. Also, in recent years, a number of studies have shown that cardiovascular events can themselves cause PTSD in more than 1 in 8 patients with acute coronary syndrome. Further, a few small studies suggest that PTSD secondary to an acute CVD event then places patients at increased risk for subsequent CVD events and mortality. In this article, we review the evidence for a link between PTSD and CVD, and discuss potential mechanisms for that association as well as future directions for research.
title: The Impact of Social Distancing and Loneliness on Adolescents' Mental Health During Covid-19
Creators: name: Barbieri, Marielena
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: The COVID-19 pandemic has severely limited physical interaction (e.g., school closures, 6ft- distances, quarantine) and disrupted the daily lives of adolescents which likely heightened levels of perceived loneliness and internalizing symptomology. Due to the novelty of social distancing regulations caused by COVID-19, little is known about the role that loneliness plays in the association between stress from social distancing regulations and adherence to these regulations, and later difficulties with internalizing symptoms. The current study examined the impact of social distancing regulations on adolescents’ wellbeing through perceived loneliness by using data from a 5-week longitudinal survey-based study conducted on parents and adolescents (aged 14-17) amid the COVID-19 pandemic. Specifically, this thesis examined how social distancing adherence and stress influenced adolescents’ loneliness, ultimately impacting their subsequent internalizing symptoms (i.e., depression and anxiety). To determine if there was a stress-buffering effect of close relationships (i.e., emotional support and conflict), moderators of links between social distancing, perceived loneliness, and internalizing symptoms were examined. Findings provided evidence that loneliness plays a unique mediating link between social distancing and internalizing symptoms. Further, preliminary evidence of specific sources of resiliency and risk in adolescents’ close relationships during the pandemic were found. Overall, the present study highlights how social distancing during the COVID-19 pandemic has impacted adolescents’ well-being during a developmental period considered a turning point for psychopathology.

description: In diesem Working Report werden Ergebnisse einer Umfrage in Nordrhein-Westfalen präsentiert, die Einstellungen der Bevölkerung zur Windenergie widerspiegeln. Die Abfragen zeigen, dass Klimaschutz-Maßnahmen, die Energiewende und der Ausbau der Windkraft große Zustimmung bei der Bevölkerung finden. Bei der Windenergie wird ein Nutzen für die lokale Gemeinschaft präferiert, bestenfalls durch direkten Bezug günstigen Stroms. Im Falle der Planung neuer Windparks werden detaillierte Informationen gewünscht, wobei wissenschaftlichen Informationsquellen am stärksten vertraut wird. Klassische Informationsveranstaltungen werden überwiegend bevorzugt, sehr viel weniger Online-Formate. Die Hälfte der Befragten würde eine Visualisierungs-App für das Smartphone benutzen. Finanzielle Beteiligung wird zwar stark von monetären Anreizen oder einem vergünstigen Stromtarif abhängig gemacht, wird aber auch durch Klimaschutz-Einstellungen beeinflusst. Planungskonflikte sollten durch Bürgerentscheide, Experten oder Bürgerversammlungen gelöst werden. Damit unterstreichen die Ergebnisse die Bedeutung von qualitätsvoller Informierung, Beteiligung und Neutralität für die Akzeptanz von Windenergie.
description: This Working Report presents results of a survey in North Rhine-Westphalia reflecting attitudes of the population towards wind energy. The survey shows that climate protection measures, the Energiewende and the expansion of wind power meet with great approval among the population. In the case of wind energy, a benefit for the local community is preferred, at best through direct purchase of cheap electricity. In the case of planning new wind farms, detailed information is desired, with scientific information sources being trusted most. Typical information events are preferred, much less online formats. Half of the respondents would use a visualization app for smartphones. Financial participation, while strongly dependent on monetary incentives or a discounted electricity tariff, is also influenced by climate protection attitudes. Planning conflicts should be resolved through citizens' decisions, experts or town hall meetings. The results underline the importance of high-quality information, participation and neutrality for the acceptance of wind energy.

description: In this paper we consider an information theoretic approach for the accounting classification process. We propose a matrix formalism and an algorithm for calculations of information theoretic measures associated to accounting classification. The formalism may be useful for further generalizations and computer-based implementation. Information theoretic measures, mutual information and symmetric uncertainty, were evaluated for daily transactions recorded in the chart of accounts of a small company during two years. Variation in the information measures due the aggregation of data in the process of accounting classification is observed. In particular, the symmetric uncertainty seems to be a useful parameter for comparing companies over time or in different sectors or different accounting choices and standards.

description: In this note we derive a new Minkowski-type inequality for closed convex surfaces in the hyperbolic 3-space. The inequality is obtained by explicitly computing the area of the family of surfaces obtained from the normal flow and then applying the isoperimetric inequality. Using the same method, we also we give elementary proofs of the classical Minkowski inequalities for closed convex surfaces in the Euclidean 3-space and in the 3-sphere.

description: In the framework of Cramer's probabilistic model of primes, we explore the exact and asymptotic distributions of maximal prime gaps. We show that the Gumbel extreme value distribution exp(-exp(-x)) is the limit law for maximal gaps between Cramer's random primes. The result can be derived from a general theorem about intervals between discrete random events occurring with slowly varying probability monotonically decreasing to zero. A straightforward generalization extends the Gumbel limit law to maximal gaps between prime constellations in Cramer's model.

title: Spatiotemporal Metabolic Modeling of  Pseudomonas aeruginosa Biofilm Expansion
Creators: name: Sourk, Robert
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: Spatiotemporal metabolic modeling of microbial metabolism is a step closer to achieving higher dimensionalities in numerical studies (in silico) of biofilm maturation. Dynamic Flux Balance Analysis (DFBA) is an advanced modeling technique because this method incorporates Genome Scale Metabolic Modeling (GSMM) to compute the biomass growth rate and metabolite fluxes. Biofilm thickness is pertinent because this variable of biofilm maturation can be measured in a laboratory (in vitro). Pseudomonas aeruginosa (P. aeruginosa) is the model bacterium used in this computational model based on previous research conducted by Dr. Michael Henson, available GSMMs, and the societal significance of patients suffering from P. aeruginosa airway infections. Spatiotemporal Flux Balance Analysis (SFBA) will be the computational method used in this thesis to simulate biofilm growth. Another level of accuracy will be introduced to SFBA which is a dynamic finite difference grid that will vary relative to the biofilm’s velocity of expansion/contraction. This novel idea is governed by a differential equation that defines the biofilm’s velocity and updates the spatial dependency of the finite difference grid which has never been done while utilizing GSMM. Environmental conditions (bulk concentrations of metabolites) are altered to investigate how varying nutrients (glucose, oxygen, lactate, nitrate) affected biofilm maturation.

Their rate is evaluated via Euler characteristic arguments and their distance using $\mathbb{Z}_2$-systolic geometry. This construction answers a queston of Zémor, who asked whether homological codes with such parameters could exist at all.

Gravitational Infall onto Molecular Filaments II. Externally Pressurized Cylinders

Year: 2013
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: In an extension of Fischera & Martin (2012a) and Heitsch (2013), two aspects of the evolution of externally pressurized, hydrostatic filaments are discussed. (a) The free-fall accretion of gas onto such a filament will lead to filament parameters (specifically, FWHM--column density relations) inconsistent with the observations of Arzoumanian et al. (2011), except for two cases: For low-mass, isothermal filaments, agreement is found as in the analysis by Fischera & Martin (2012b). Magnetized cases, for which the field scales weakly with the density as $B\propto n^{1/2}$, also reproduce observed parameters. (b) Realistically, the filaments will be embedded not only in gas of non-zero pressure, but also of non-zero density. Thus, the appearance of sheet-embedded filaments is explored. Generating a grid of filament models and comparing the resulting column density ratios and profile shapes with observations suggests that the three-dimensional filament profiles are intrinsically flatter than isothermal, beyond projection and evolution effects.

description: Each distributor between categories enriched over a small quantaloid Q gives rise to two adjunctions between the categories of contravariant and covariant presheaves, and hence to two monads. These two adjunctions are respectively generalizations of Isbell adjunctions and Kan extensions in category theory. It is proved that these two processes are functorial with infomorphisms playing as morphisms between distributors; and that the free cocompletion functor of Q-categories factors through both of these functors.

description: The possibility of electron beam guiding is theoretically explored on the surface of a topological insulator through the proximity interaction with a magnetic material. The electronic band modification induced by the exchange coupling at the interface defines the path of electron propagation in analogy to the optical fiber for photons. Numerical simulations indicate the guiding efficiency much higher than that in the "waveguide" formed by an electrostatic potential barrier such as p-n junctions. Further, the results illustrate effective flux control and beam steering that can be realized by altering the magnetization/spin texture of the adjacent magnetic materials. Specifically, the feasibility to switch on/off and make a large-angle turn is demonstrated under realistic conditions. Potential implementation to logic and interconnect applications is also examined in connection with electrically controlled magnetization switching.

description: BACKGROUND: Depressive symptoms are an established predictor of mortality and major adverse cardiac events (defined as nonfatal myocardial infarction or hospitalization for unstable angina or urgent/emergency revascularizations) in patients with acute coronary syndrome (ACS). This study was conducted to determine the acceptability and efficacy of enhanced depression treatment in patients with ACS. METHODS: A 3-month observation period to identify patients with ACS and persistent depressive symptoms was followed by a 6-month randomized controlled trial. From January 1, 2005, through February 29, 2008, 237 patients with ACS from 5 hospitals were enrolled, including 157 persistently depressed patients randomized to intervention (initial patient preference for problem-solving therapy and/or pharmacotherapy, then a stepped-care approach; 80 patients) or usual care (77 patients) and 80 nondepressed patients who underwent observational evaluation. The primary outcome was patient satisfaction with depression care. Secondary outcomes were depressive symptom changes (assessed with the Beck Depression Inventory), major adverse cardiac events, and death. RESULTS: At the end of the trial, the proportion of patients who were satisfied with their depression care was higher in the intervention group (54% of 80) than in the usual care group (19% of 77) (odds ratio, 5.4; 95% confidence interval [CI], 2.2-12.9 [P < .001]). The Beck Depression Inventory score decreased significantly more (t(155) = 2.85 [P = .005]) for intervention patients (change, -5.7; 95% CI, -7.6 to -3.8; df = 155) than for usual care patients (change, -1.9; 95% CI, -3.8 to -0.1; df = 155); the depression effect size was 0.59 of the standard deviation. At the end of the trial, 3 intervention patients and 10 usual care patients had experienced major adverse cardiac events (4% and 13%, respectively; log-rank test, chi(2)(1) = 3.93 [P = .047]), as well as 5 nondepressed patients (6%) (for the intervention vs nondepressed cohort, chi(2)(1) = 0.48 [P = .49]). CONCLUSION: Enhanced depression care for patients with ACS was associated with greater satisfaction, a greater reduction in depressive symptoms, and a promising improvement in prognosis.
title: Incorporating Epoxy and Amine into Poly(Methyl Methacrylate) for a Crosslinkable Waterborne Coating
Creators: name: Song, Jichao
Publisher: name: University of Massachusetts Amherst

description: The global market for waterborne coatings will continue to grow because alternative solventborne coatings emit environmentally hazardous volatile organic compounds (VOCs). However, most waterborne coatings are softer than solventborne crosslinked thermoset coatings because they feature thermoplastic polymer dispersions. To overcome these challenges, in this thesis we suggest a novel crosslinkable aqueous dispersion system that incorporates epoxy and amine particles into poly(methyl methacrylate) (PMMA); the particles will react when water (the solvent) evaporates, offering a potential one-component (1K) reactive system. Emulsion polymerization was used to synthesize the particles with the help of surfactants. Epoxy and amine particles were successfully incorporated during the synthesis of PMMA and formed a two-component (2K) aqueous dispersion. In this process, a non-ionic surfactant, Triton X405 (TX405), was used to prevent interactions with the amine particles. Nuclear magnetic resonance (NMR) was used to determine the actual incorporation ratios of epoxy and amine and we found an epoxy incorporation plateau. Dynamic light scattering (DLS) was used to determine the particle size distributions and a uniform distribution was observed. The pendulum test and the pencil test were used for coating hardness, which surpassed currently marketed waterborne coatings. The resulting aqueous dispersions could be cured under facile conditions, i.e., in air and at low temperatures. An increase in Tg was observed after crosslinking. Different mechanical properties were observed when the coatings were cured at different temperatures, 25°C, 70°C, and 100°C. These results suggest that we have successfully formed crosslinked coatings that contain our epoxy and amine incorporated particles, with mechanical properties comparable to the traditional solventborne coatings.
Hadron production measurement from NA61/SHINE

description: New results from the NA61/SHINE experiment on the determination of charged hadron yields in proton-carbon interactions are presented. They aim to improve predictions of the neutrino flux in the T2K experiment. The analysis is based on the main dataset collected by NA61/SHINE in the year 2009. The data were recorded using a secondary-proton beam of 31 GeV/$c$ momentum from CERN SPS which impinges on a graphite target. To determine the inclusive production cross section for charged pions, kaons and protons a thin target was exploited. Results of this measurement are used in the T2K beam simulation program to reweight hadron yields at the interaction vertex. At the same time, NA61/SHINE results obtained with the T2K replica target allow to constrain hadron yields at the surface of the target. This allows to constrain up to 90% of the neutrino flux, thus reducing significantly the model dependence of the neutrino beam prediction. All measured spectra are compared to predictions of hadron production models.

description: AIMS: Positive affect is believed to predict cardiovascular health independent of negative affect. We examined whether higher levels of positive affect are associated with a lower risk of coronary heart disease (CHD) in a large prospective study with 10 years of follow-up. METHODS AND RESULTS: We examined the association between positive affect and cardiovascular events in 1739 adults (862 men and 877 women) in the 1995 Nova Scotia Health Survey. Trained nurses conducted Type A Structured Interviews, and coders rated the degree of outwardly displayed positive affect on a five-point scale. To test that positive affect predicts incident CHD when controlling for depressive symptoms and other negative affects, we used as covariates: Center for Epidemiological Studies Depressive symptoms Scale, the Cook Medley Hostility scale, and the Spielberger Trait Anxiety Inventory. There were 145 (8.3%) acute non-fatal or fatal ischaemic heart disease events during the 14 916 person-years of observation. In a proportional hazards model controlling for age, sex, and cardiovascular risk factors, positive affect predicted CHD (adjusted HR, 0.78; 95% CI 0.63-0.96 per point; P = 0.02), the covariate depressive symptoms continued to predict CHD as had been published previously in the same patients (HR, 1.04; 95% CI 1.01-1.07 per point; P = 0.004) and hostility and anxiety did not (both P > 0.05). CONCLUSION: In this large, population-based study, increased positive affect was protective against 10-year incident CHD, suggesting that preventive strategies may be enhanced not only by reducing depressive symptoms but also by increasing positive affect.
title: Counting Sequences Are Processed Across Multiple Levels Of Cortical Hierarchy
Creators: name: Zaleznik, Eli
Publisher: name: University of Massachusetts Amherst
Year: 2022

description: Learning the count list (one, two, three, …) is a critical stepping-stone for the acquisition of number concepts. Most research about counting, however, is done in the behavioral domain, and little is known about the neural representations underlying counting sequences. Here, we test the hypothesis that transitional knowledge within a counting sequence exist both at sensory and conceptual (ordinal and magnitude) levels. To test this hypothesis, we employed a passive-listening violation-to-expectation fMRI paradigm where adult participants heard auditory count sequences that were correct (4 5 6 7) or violated at the end (4 5 6 8; consecutiveness) and, orthogonally, that were ordered or unordered (orderedness). Another orthogonal dimension was the manipulation of sensory sequence violation where the voice speaking the numbers was consistent throughout the trial or could change on the last number (voice identity). This 2x2x2 factorial design was analyzed using univariate and multivariate pattern analyses. Three clusters in the right fronto-parietal network (BA44, BA46, and IPS) showed greater neural response to violations to orderedness. Of the three clusters, the anterior IFG (BA46) demonstrated the encoding of consecutiveness. Interestingly, the bilateral STG, which showed a robust effect to violations in voice identity, also demonstrated the encoding of consecutiveness. These results indicate that a right-lateralized fronto-parietal network activity can differentiate between a count list and random numbers, while BA46 and bilateral STG respond specifically to violations of the count sequence, suggesting specific mechanisms in the brain for processing consecutive numbers in both the perceptual and cognitive levels.

description: We present a hierarchically blocked one-sided Jacobi algorithm for the singular value decomposition (SVD), targeting both single and multiple graphics processing units (GPUs). The blocking structure reflects the levels of GPU's memory hierarchy. The algorithm may outperform MAGMA's dgesvd, while retaining high relative accuracy. To this end, we developed a family of parallel pivot strategies on GPU's shared address space, but applicable also to inter-GPU communication. Unlike common hybrid approaches, our algorithm in a single GPU setting needs a CPU for the controlling purposes only, while utilizing GPU's resources to the fullest extent permitted by the hardware. When required by the problem size, the algorithm, in principle, scales to an arbitrary number of GPU nodes. The scalability is demonstrated by more than twofold speedup for sufficiently large matrices on a Tesla S2050 system with four GPUs vs. a single Fermi card.

description: We systematically searched published empirical research on depression and cardiovascular disease (CVD) and found 494 unique articles published in 2009. Several particularly notable and provocative findings and controversies emerged from this survey of the 2009 literature. First, multiple large observational studies found that antidepressant use was associated with increased risk of incident stroke, CVD, or sudden cardiac death. Second, four randomized controlled trials on depression interventions in CVD patients reported important efficacy results that should guide future trials. Finally, the vigorous debate on whether patients with CVD should be routinely screened (and subsequently treated) for depression continued in 2009 even as some observed that routine screening for CVD in depressed patients is more evidence-based and appropriate. This article reviews these selected provocative findings and controversies from our search and explores their clinical implications.

description: These Sessional Clippings books cover the period 1891 to 1972, and include newspaper accounts written by various legislative reporters who covered debates occurring in the British Columbia Legislative Assembly. Transcripts of debates of the Legislative Assembly (Hansard) were not published in B.C. until 1970; hence these "Sessional Clipping Books" augment the "Journals", the record of daily proceedings of the Legislative Assembly. Selected clippings from various newspapers including the Vancouver Sun, the Vancouver Province, the Colonist, and the Times newspapers, relating to the newspaper reports concerning activities of the Legislature. The original sessional clippings books comprise 351 ledger size print volumes, held at the Legislative Library in Victoria BC. The print volumes were microfilmed onto 26 reels in 1977 under a Tri University Libraries (TRIUL) project by Precision Micrographic Services (Vancouver, B.C.), with the permission of the Legislative Library, Victoria, British Columbia. This digital collection was created by scanning the 26 microfilm reels.

description: We study thermalization on rotating probe branes in AdS_5 x S^5 background in the presence of constant external electric and magnetic fields. In the AdS/CFT framework this corresponds to thermalization in the flavour sector in field theory. The horizon appears on the worldvolume of the probe brane due to its rotation in one of the sphere directions. For both electric and magnetic fields the behaviour of the temperature is independent of the probe brane dimension. We also study the open string metric and the fluctuations of the probe brane in such a set-up. We show that the temperatures obtained from open string metric and observed by the fluctuations are larger than the one calculated from the induced metric.

Additionally, we put forward observational constraints that any model of this planet-star system will have to match. We find two quiescent spells of ~30 orbital periods each where the transit depth is <0.1%, followed by relatively deep transits. Additionally, we find periods of on-off behaviour where >0.5% deep transits are followed by apparently no transit at all. Apart from these isolated events we find neither significant correlation between consecutive transit depths nor a correlation between transit depth and stellar intensity. We find a three-sigma upper limit for the secondary eclipse of 4.9*10^-5, consistent with a planet candidate with a radius of less than 4600 km. Using the short cadence data we find that a 1-D exponential dust tail model is insufficient to explain the data. We improved our model to a 2-D, two-component dust model with an opaque core and an exponential tail. Using this model we fit individual eclipses observed in short cadence mode. We find an improved fit of the data, quantifying earlier suggestions by Budaj (2013) of the necessity of at least two components. We find that deep transits have most absorption in the tail, and not in a disk-shaped, opaque coma, but the transit depth and the total absorption show no correlation with the tail length.

description: Thermodynamic Casimir forces of film systems in the O$(n)$ universality classes with Dirichlet boundary conditions are studied below bulk criticality. Substantial progress is achieved in resolving the long-standing problem of describing analytically the pronounced minimum of the scaling function observed experimentally in $^4$He films $(n=2)$ by R. Garcia and M.H.W. Chan, Phys. Rev. Lett. ${\bf 83}, 1187 \;(1999)$ and in Monte Carlo simulations for the three-dimensional Ising model ($n=1$) by O. Vasilyev et al., EPL ${\bf 80}, 60009 \;(2007)$. Our finite-size renormalization-group approach yields excellent agreement with the depth and the position of the minimum for $n=1$ and semiquantitative agreement with the minimum for $n=2$. Our theory also predicts a pronounced minimum for the $n=3$ Heisenberg universality class.

description: Spin chains are among the simplest physical systems in which electron-electron interactions induce novel states of matter. Here we show that the combination of atomic scale engineering and spectroscopic capabilities of state of the art scanning tunnel microscopy enables probing the fractionalized edge states of individual atomic scale S=1 spin chains. These edge states arise from the topological order of the ground state in the Haldane phase. We also show that the Haldane gap and the spin-spin correlation length can be measured with the same technique.

description: CONTEXT: Depression consistently predicts recurrent events and mortality in patients with acute coronary syndrome (ACS), but it has 2 core diagnostic criteria with distinct biological correlates-depressed mood and anhedonia (loss of pleasure or interest). OBJECTIVE: To determine if depressed mood and/or anhedonia predict 1-year medical outcomes for patients with ACS. DESIGN: Observational cohort study of post-ACS patients hospitalized between May 2003 and June 2005. Within 1 week of admission, patients underwent a structured psychiatric interview assessing clinically impairing depressed mood, anhedonia, and major depressive episode (MDE). Also assessed were the Global Registry of Acute Coronary Events risk score, Charlson comorbidity index, left ventricular ejection fraction, antidepressant use, and depressive symptom severity using the Beck Depression Inventory. SETTING: Cardiac units of 3 university hospitals in New York and Connecticut. PARTICIPANTS: Consecutive sample of 453 patients with ACS (age, 25-93 years; 42% women). MAIN OUTCOMES MEASURES: All-cause mortality (ACM) and documented major adverse cardiac events (MACEs)-myocardial infarction, hospitalization for unstable angina, or urgent/emergency coronary revascularization)-actively surveyed for 1 year after admission. RESULTS: There were 67 events (16 deaths and 51 MACEs; 14.8%): 108 (24%) and 77 (17%) patients had anhedonia and depressed mood, respectively. Controlling for sex, age, and medical covariates, anhedonia (adjusted hazard ratio, 1.58; 95% confidence interval, 1.16-2.14; P < .01) was a significant predictor of combined MACE and ACM, but depressed mood was not. Anhedonia continued to significantly predict outcomes (P < .05) when additionally controlling for MDE diagnosis or depressive symptom severity. Findings were confirmed using depressed mood and anhedonia subscores from the Beck Depression Inventory in place of clinician interview ratings. CONCLUSIONS: Anhedonia identifies risk of MACE and ACM beyond that of established medical prognostic indicators, including MDE and depressive symptom severity. Correlates of anhedonia may add to the understanding of the link between depression and heart disease.

description: Abstract The European Union (EU) School Fruit and Vegetables Scheme is a nutrition policy program. It has three actions: delivery of fruit and vegetables in schools, accompanying educational and information measures. The aim of this study is to identify barriers and facilitators to the implementation of the Scheme as perceived by implementers at government level. This work is a qualitative, exploratory study using the Consolidated Framework for Implementation Research (CFIR) to guide data collection and analysis. Twenty-three semi-structured interviews were conducted with representatives ( n  = 29) from agriculture, health and education, across 10 EU member states and the EU. Qualitative data were coded inductively. Themes were mapped to constructs of the CFIR. We found content in regard to 19 out of 26 constructs of the CFIR. Some example constructs are: adaptability, external policy and incentives, networks and communications, knowledge and beliefs and executing. Flexibility in how the scheme is designed and implemented and newly established cooperation between implementing ministries are facilitators. However, the timing of the yearly budget allocation is a barrier. Taking EU funding for granted is a potential disincentive to improvement, although the EU funding facilitates sustainability. Despite agreement on what the overall goals of the Scheme are, there is ambiguity as to what the perceived primary goal is, which may be a barrier. Some goal ambiguity may be useful at the supranational level, enabling politically acceptable framing and continuation of the financing of the Scheme, but this translates into a potential barrier to design and implementation at country and school level.
White List of Ranked Far-Future Accelerator Options
Creators: name: ARIES WP6 Members

Year: 2021

description: Worldwide several novel accelerator technologies and future collider scenarios are being proposed along with possible advanced scientific applications. Among these are photon colliders, the Gamma factory, two versions of muon colliders, the use of plasmas, crystals or nanotubes for bending or acceleration, and employing storage rings or other accelerator technologies for the detection or acceleration of gravitational waves. Based on the results of six ARIES workshops, and through an online survey of the workshop participants, a ranking of far-future accelerator options has been performed, with regard to importance, maturity, potential impact on society, risk of failure and time scale for practical realization. Here, we present the resulting White List of Ranked Far-Future Accelerator Options, with recommendations for high-priority R&D foci and the expected time scales for practical realizations.

Local instabilities in magnetized rotational flows: A short-wavelength approach

description: We perform a local stability analysis of rotational flows in the presence of a constant vertical magnetic field and an azimuthal magnetic field with a general radial dependence. Employing the short-wavelength approximation we develop a unified framework for the investigation of the standard, the helical, and the azimuthal version of the magnetorotational instability, as well as of current-driven kink-type instabilities. Considering the viscous and resistive setup, our main focus is on the case of small magnetic Prandtl numbers which applies, e.g., to liquid metal experiments but also to the colder parts of accretion disks. We show that the inductionless versions of MRI that were previously thought to be restricted to comparably steep rotation profiles extend well to the Keplerian case if only the azimuthal field slightly deviates from its current-free (in the fluid) profile. We find an explicit criterion separating the pure azimuthal inductionless magnetorotational instability from the regime where this instability is mixed with the Tayler instability. We further demonstrate that for particular parameter configurations the azimuthal MRI originates as a result of a dissipation-induced instability of the Chandrasekhar's equipartition solution of ideal magnetohydrodynamics.
