description: In situ generated 2,4-diaryl substituted münchnones from 2-(4-substitutedphenyl)-2-(N-methyl-N-4-substitutedbenzamido)acetic acids react with acetic anhydride in the presence of 2-nitromethylene thiazolidine, which is most likely acting as a base, and unexpectedly undergo a Dakin–West type reaction and a concurrent autoxidation reaction leading to the formation of (E)-1-(N,4-dimethylbenzamido)-1-(4-fluorophenyl)prop-1-en-2-yl acetate, 4-substitutedphenyl-N-methyl-N-(4-substitutedbenzoyl) benzamides and p-substituted benzoic acids. In addition, a novel and efficient access to N-acyl urea derivatives is described by the reaction between 2-(4-substitutedphenyl)-2-(N-methyl-N-4-substitutedbenzamido)acetic acids and cyclohexyl, isopropyl carbodiimides in the presence of a base. The structures of all new products were identified on the basis of NMR and IR spectra, along with X-ray diffraction data and HRMS measurements.

description: In this paper, we use the equation of state based on a modification of 2+1 flavors Nambu-Jona- Lasinio (NJL) model to study the quark matter of hybrid stars. For comparison, we utilize five EOSs of the relativistic mean-field (RMF) model to describe the hadronic phase. With the 3- window crossover interpolation approach, we try to construct relatively soft hybrid EOSs but find the maximum masses of hybrid stars do not differ too much. The results are quite close to two solar mass, which is consistent with the mass constraint of PSR J0348+0432. Furthermore it is noteworthy that the heaviest stable stars have central densities higher than that of the deconfinement transition thus suggesting a pure quark core in the hybrid star.

description: Introduction Decision Making Capacity (DMC) refers to an individual’s ability to make a reasoned and informed decision. In Ireland the older population is increasing and associated with ageing are functional and cognitive decline which are linked to reduced decision making abilities. In an acute hospital an individual’s DMC is often questioned and a DMC assessment takes place. Occupational therapists are involved in this process and evaluate an individual’s cognitive and functional abilities. This study sought to explore the practices of occupational therapists in this process. Aims and Objectives Aim: To explore occupational therapists assessment practices in DMC of the older person to live independently. Objectives: To examine occupational therapists understanding of DMC, assessments used in process and to explore the outcomes of assessment findings. Methods The study employed a qualitative description design using semi-structured interviews with ten hospital occupational therapists from seven hospitals. Key themes emerged from analysing the data using thematic analysis. Results Three themes emerged from the data; Pre-assessment, Assessment and Post Assessment. Pre-assessment, participants formed their understanding of DMC and sought to build a detailed picture of the individual prior to their hospital admission. The assessment phase consisted of standardised and non-standardised assessments. Standardised assessments were used to evaluate cognitive performance while non- standardised assessments evaluated an individual’s Instrument Activities of Daily Living (IADL’s). Assessments focussed on IADL performance and if possible were completed in the home environment. Post Assessment all results were documented in the medical chart and verbally to the multidisciplinary team and focussed on the level of assistance an individual would require for independent living. Conclusion Observational assessments of IADL’s in particular in the individual’s home were considered the most pertinent part of the occupational therapy assessment. Implications Occupational therapists require practice guidelines and further training to support their involvement in this process.

description: The electronic structure of Li-doped Ni$_{1-x}$Fe$_x$O has been investigated using photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). The Ni $2p$ core-level PES and XAS spectra were not changed by Li doping. In contrast, the Fe$^{3+}$ intensity increased with Li doping relative to the Fe$^{2+}$ intensity. However, the increase of Fe$^{3+}$ is only $\sim 5%$ of the doped Li content, suggesting that most of the doped holes enter the O $2p$ and/or the charge-transferred configuration Ni $3d^8\underline{L}$. The Fe 3d partial density of states and the host valence-band emission near valence-band maximum increased with Li content, consistent with the increase of electrical conductivity. Based on these findings, percolation of bound magnetic polarons is proposed as an origin of the ferromagnetic behavior.

Hanbury Brown to measure stellar diameters by Intensity Interferometry in the late 60's. VHE gamma-ray observatories to be constructed over the coming decade will involve several tens of telescopes of similar or greater sizes. Used as intensity interferometers, they will provide hundreds of independent baselines. Now is the right time to re-assess the potential of intensity interferometry so that it can be taken into consideration in the design of these large facilities.

description: Background: Aggression is common after an acquired brain injury (ABI). Cognitive behavioural therapy (CBT) is a form of psychotherapy, in which therapists help patients to identify their maladaptive behaviours. Objective: The objective of this systematic review and meta-analysis was to evaluate the effectiveness of CBT interventions in treating aggression in an ABI population. Methods: A systematic literature search was conducted using: PubMed/MEDLINE, CINAHL, EMBASE and PsycINFO from database inception to August 2016. English articles were included if: at least 50% of the study sample had a moderate to severe ABI, there were at least three adult human participants, and use of a CBT intervention for the treatment of aggression. Results: Seven articles met inclusion criteria: one RCT, an RCT crossover and five pre-post trials. Of these, four articles were included in a pre-post meta-analysis for treatment efficacy on subscales of the State Trait Anger Expression Inventory (STAXI) and STAXI-2 outcome measures. The meta-analysis found CBT was effective in moderating the external behaviours of aggression, but not internal anger. Conclusion: The differences in outcomes may be related to the differential management of anger expression and anger suppression. CBT shows promise, but further studies with comparator groups are needed before conclusions about its efficacy can be made.
Multiple Outflow Episodes from Protostars:3-D Models of Intermittent Jets

description: Short abstract: We present fully 3-D simulations of supersonic, radiatively cooling intermittent jets with intermediate and long variability periods (that is, periods of the order of or longer than, the dynamical time scale of the jet). Variations of intermediate period elucidate the formation and evolution of chains of internal regularly spaced radiative shocks, which in this work are identified with the observed emission knots of protostellar jets. Variations of long period elucidate the formation of multiple bow shock structures separated by long trails of diffuse gas, which resemble those observed in systems like HH111 and HH46/47. The time variability of the outflow is probably associated with observed irruptive events in the accretion process around the protostars. In our simulations, the outflow variations are produced by periodically turning on the outflow with a highly supersonic velocity and periodically turning off it to a low velocity regime. In the case of velocity variations of intermediate period, we find, as in previous work, that the shock structures form a train of regularly spaced emitting features which move away from the source with a velocity close to that of the outflow, have high radial motions, and produce low intensity spectra, as required by the observations. As they propagate downstream, the shocks widen and dissipate due to the expulsion of material sideways to the cocoon by the high pressure gradients of the postshock gas. This fading explains the most frequent occurence of knots closer to the driving source. In the case of the long period velocity variability, our simulations have produced a pair of bow-shock-like structures separated by a trail almost

Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Methods: Every patient admitted at the Acute Stroke Unit (ASU) in University Hospital Limerick was considered for recruitment to this descriptive cohort study. Participants wore an accelerometer for the first seven days post discharge home from the ASU. The data from this was compared to self-reported physical activity (PA) levels as measured by the International Physical Activity Questionnaire using the Spearman rank correlation coefficient. Secondary measures of age, cognition, balance, self-efficacy, function, anxiety and depression were examined using a mixed linear regression model to determine whether they influenced levels of physical activity following a stroke. Results: A total of 21 participants were recruited during the study period from 1/10/15 to 29/2/16. Analysis demonstrated that no participant reached the recommended 10,000 steps per day. The median number of steps taken per day as measured by the accelerometer was 4023 with an interquartile range (IQR) of 2724 steps (minimum 1745 – maximum 9824 steps/day). The median MET’s per day as measured by the accelerometer was 30.53 (IQR 1.45, minimum 26.83 – maximum 102.55). Conclusions: Following discharge home from the ASU patients do not meet the recommended levels of physical activity. There is a poor correlation between self- reported and objective levels of physical activity in this cohort. This study did not establish a relationship between any of the secondary measures and physical activity. Implications of findings: Stroke survivors are largely inactive in the acute period following discharge home from the ASU. Improved identification of barriers to PA and effective interventions are required to improve outcomes for patients post stroke to reduce the risk of stroke recurrence and optimise their outcome.

description: Einstein-dilaton-Gauss-Bonnet gravity is a well-motivated alternative theory of gravity that emerges naturally from string theory. While black hole solutions have been known in this theory in numerical form for a while, an approximate analytical metric was obtained recently by some of us, which allows for faster and more detailed analysis. Here we test the accuracy of the analytical metric in the context of X-ray reflection spectroscopy. We analyze innermost stable circular orbits (ISCO) and relativistically broadened iron lines and find that both the ISCO and iron lines are determined sufficiently accurately up to the limit of the approximation. We also find that, though the ISCO increases by about 7% as dilaton coupling increases from zero to extremal values, the redshift at ISCO changes by less than 1%. Consequently, the shape of the iron line is much less sensitive to the dilaton charge than expected.

Η συνταγματική δημοκρατία στην Ευρώπη και την Ελλάδα ήρθε αντιμέτωπη με μία πρωτόγνωρη κατάσταση η οποία την έθεσε προ των ευθυνών της.

description: Introduction  The number of Irish older adults receiving long term care is steadily growing in line with increased life expectancy. Nursing home residents are typically sedentary, leading to poor health and functional outcomes in this population. There is a lack of research concerning the exercise beliefs of this inactive subgroup of the older adult population. Aims and Objectives  The primary aim of this study was to examine the hypothesis that older adults in a nursing home have poor outcome expectations for exercise, and reduced self- efficacy for exercise, when compared to older adults residing in the community. A secondary aim was to assess if an association exists between these exercise beliefs and the participants’ functional scores, number of comorbidities and psychological health. Methods  A cross sectional, case control study design was employed, using a sample of convenience. Twenty two nursing home residents, and twenty active retirement group members (≥65 years) living independently in the community completed a written survey. Exercise beliefs were measured using the Outcome Expectations for Exercise Scale (OEE), and the Self-Efficacy for Exercise Scale (SEE).Secondary outcome measures were the Barthel Index of Activities of Daily Living (BI), number of comorbidities, and the Geriatric Depression Scale-15 (GDS-15). Results  The groups were significantly different in terms of age (p=0.03), number of comorbidities (p= Conclusion  Self-efficacy for exercise is lower amongst nursing home residents than in community dwelling older adults. Both groups demonstrate high outcome expectations for exercise. The presence of depressive symptoms is significantly associated with lower self-efficacy and outcome expectations for exercise. It is evident that the presence of depressive symptoms may represent a significant barrier to participation in physical activity for older adults both in nursing homes and in the community.

B^F Theory and Flat Spacetimes

description: We propose a reduced constrained Hamiltonian formalism for the exactly soluble $B \wedge F$ theory of flat connections and closed two-forms over manifolds with topology $Σ^3 \times (0,1)$. The reduced phase space variables are the holonomies of a flat connection for loops which form a basis of the first homotopy group $π_1(Σ^3)$, and elements of the second cohomology group of $Σ^3$ with value in the Lie algebra $L(G)$. When $G=SO(3,1)$, and if the two-form can be expressed as $B= e\wedge e$, for some vierbein field $e$, then the variables represent a flat spacetime. This is not always possible: We show that the solutions of the theory generally represent spacetimes with ``global torsion''. We describe the dynamical evolution of spacetimes with and without global torsion, and classify the flat spacetimes which admit a locally homogeneous foliation, following Thurston's classification of geometric structures.

description: Background: Dual antiplatelet therapy (DAPT) is routinely prescribed after transcatheter aortic valve replacement (TAVR) despite the lack of definitive data demonstrating its superiority over mono-antiplatelet therapy (MAPT). We aim to investigate the benefits of DAPT versus MAPT and at different follow-up time points post TAVR. Methods: A systematic search was conducted for studies investigating DAPT vs MAPT in patients who underwent TAVR. The primary outcome was net adverse clinical events (NACE) at longest reported follow-up, defined as a composite end-point of all-cause mortality, major stroke, myocardial infarction (MI), and combined life threatening and major bleeding. Secondary endpoints included each outcome individually. We performed subgroup analysis according to study type (randomized control trials versus observational studies) and follow-up duration post-TAVR (≤ 30 days, between 3 to 6 months, and ≥ 1 year). Results: Twelve studies with 9,650 patients were included. Post-TAVR MAPT was associated with significantly reduced NACE (0.60 [0.45, 0.81], p Conclusion: MAPT is associated with improved outcomes compared to DAPT in the first 30 days post-TAVR with no difference in outcomes on longer term follow up. Future prospective, adequately powered, multicenter, placebo controlled, randomized double blinded cohort studies are warranted to confirm our findings.
The Connection Between Low-Mass X-ray Binaries and (Millisecond) Pulsars: A Binary Evolution Perspective

description: I review the evolutionary connection between low-mass X-ray binaries (LMXBs) and pulsars with binary companions (bPSRs) from a stellar binary evolution perspective. I focus on the evolution of stellar binaries with end-states consisting of a pulsar with a low-mass (<1.0 solar mass) companion, starting at the point the companion's progenitor first initiates mass transfer onto the neutron star. Whether this mass transfer is stable and the physics driving ongoing mass transfer partitions the phase space of the companions's initial mass and initial orbital period into five regions. The qualitative nature of the mass-transfer process and the binary's final end-state differ between systems in each region; four of these regions each produce a particular class of LMXBs. I compare the theoretical expectations to the populations of galactic field LMXBs with companion-mass constraints and field bPSRs. I show that the population of accreting millisecond pulsars are all identified with only two of the four LMXB classes and that these systems do not have readily identifiable progeny in the bPSR population. I discuss which sub-populations of bPSRs can be explained by binary evolution theory and those that currently are not. Finally I discuss some outstanding questions in this field.

description: A series of predictions are worked out in order to put the minimal $SU(5)$ supergravity model under experimental test. Using the two-loop gauge coupling renormalization group equations, with the inclusion of supersymmetric threshold corrections, we calculate a new value for the proton decay rate in this model and find that SuperKamiokande and Gran Sasso should see the proton decay mode $p\to\barνK^+$ for most of the allowed parameter space. A set of physically sensible assumptions and the cosmological requirement of a not too young Universe give us a rather restrictive set of allowed points in the parameter space, which characterizes this model. This set implies the existence of interesting correlations among various masses: either the lightest chargino and the next-to-lightest neutralino are below $\approx100\GeV$ (and therefore observable at the Tevatron) or the lightest Higgs boson is below $\approx50\GeV$ (and therefore observable at LEP I-II). These tests are crucial steps towards selecting the correct low-energy effective supergravity model. We also comment on the compatibility of the model with $\sin^2θ_w(M_Z)$ measurements as a function of $α_3(M_Z)$.

description: Upon an expansion of all of the searches for redshifted HI 21-cm absorption (0.0021 < z 5.19), we update recent results regarding the detection of 21-cm in the non-local Universe. Specifically, we confirm that photo-ionisation of the gas is the mostly likely cause of the low detection rate at high redshift, in addition to finding that at z < 0.1 there may also be a decrease in the detection rate, which we suggest is due to the dilution of the absorption strength by 21-cm emission. By assuming that associated and intervening absorbers have similar cosmological mass densities, we find evidence that the spin temperature of the gas evolves with redshift, consistent with heating by ultra-violet photons. From the near--infrared (3.4, 4.6 and 12 micron) colours, we see that radio galaxies become more quasar-like in their activity with increasing redshift. We also find that the non-detection of 21-cm absorption at high redshift is not likely to be due to the selection of gas-poor ellipticals, in addition to a strong correlation between the ionising photon rate and the [3.4] - [4.6] colour, indicating that the UV photons arise from AGN activity. Like previous studies, we find a correlation between the detection of 21-cm absorption and the [4.6] - [12] colour, which is a tracer of star-forming activity. However, this only applies at the lowest redshifts (z < 0.1), the range considered by the other studies.

description: We report quantitative measurements of nanoscale permittivity and conductivity using tuning-fork (TF) based microwave impedance microscopy (MIM). The system is operated under the driving amplitude modulation mode, which ensures satisfactory feedback stability on samples with rough surfaces. The demodulated MIM signals on a series of bulk dielectrics are in good agreement with results simulated by finite-element analysis. Using the TF-MIM, we have visualized the evolution of nanoscale conductance on back-gated $MoS_2$ field effect transistors and the results are consistent with the transport data. Our work suggests that quantitative analysis of mesoscopic electrical properties can be achieved by near-field microwave imaging with small distance modulation.

description: Theoretical studies on the geometry, electronic structure and spin multiplicity of Sc, Ti and V doped Na$_n$ (n = 4, 5, 6) clusters have been carried out within a gradient corrected density functional approach. Two complementary approaches including all-electron calculations on free clusters, and supercell calculations using planewave pseudopotential and projector augmented wave formalisms have been carried out. It is shown that spin magnetic moments of the transition metal atoms, the magnitude of host polarization, and the sign of the host polarization all change with the number of alkali atoms. In particular the transition metal atoms are shown to attain spin moments that are higher than their atomic values. The role of hybridization between the transition atom d-states and the alkali $sp$-states is highlighted to account for the evolutions in the spin moments and host polarization.

description: The gravitational evolution of the genus of the density field in large-scale structure is analytically studied in a weakly nonlinear regime using second-order perturbation theory. Weakly nonlinear evolution produces asymmetry in the symmetric genus curve for Gaussian initial density field. The effect of smoothing the density field in perturbation theory on the genus curve is also evaluated and gives the dependence of the asymmetry of the genus curve on spectra of initial fluctuations.

description: We present a kinetic-energy density-functional theory and the corresponding kinetic-energy Kohn-Sham (keKS) scheme on a lattice and show that by including more observables explicitly in a density-functional approach already simple approximation strategies lead to very accurate results. Here we promote the kinetic-energy density to a fundamental variable along side the density and show for specific cases (analytically and numerically) that there is a one-to-one correspondence between the external pair of on-site potential and site-dependent hopping and the internal pair of density and kinetic-energy density. Based on this mapping we establish two unknown effective fields, the mean-field exchange-correlation potential and the mean-field exchange-correlation hopping, that force the keKS system to generate the same kinetic-energy density and density as the fully interacting one. We show, by a decomposition based on the equations of motions for the density and the kinetic-energy density, that we can construct simple orbital-dependent functionals that outperform the corresponding exact-exchange Kohn-Sham (KS) approximation of standard density-functional theory. We do so by considering the exact KS and keKS systems and compare the unknown correlation contributions as well as by comparing self-consistent calculations based on the mean-field exchange for the keKS and the exact-exchange for the KS system, respectively.
Testing for Preferred-Frame Effects in Gravity with Artificial Earth Satellites

description: As gravity is a long-range force, one might a priori expect the Universe's global matter distribution to select a preferred rest frame for local gravitational physics. At the post-Newtonian approximation, two parameters suffice to describe the phenomenology of preferred-frame effects. One of them has already been very tightly constrained (|alpha_2| < 4 x 10^-7, 90% C.L.), but the present bound on the other one is much weaker (|alpha_1| < 5 x 10^-4, 90% C.L.). It is pointed out that the observation of particular orbits of artificial Earth satellites has the potential of improving the alpha_1 limits by a couple of orders of magnitude, thanks to the appearance of small divisors which enhance the corresponding preferred-frame effects. There is a discrete set of inclinations which lead to arbitrarily small divisors, while, among zero-inclination (equatorial) orbits, geostationary ones are near optimal. The main alpha_1-induced effects are: (i) a complex secular evolution of the eccentricity vector of the orbit, describable as the vectorial sum of several independent rotations; and (ii) a yearly oscillation in the longitude of the satellite.

description: Σε παγκόσμιο επίπεδο, η κατανάλωση γάλακτος και των παραπροϊόντων του, είναι αδιαμφισβήτητα μία από τις κύριες και καθημερινές τροφές για κάθε καταναλωτή. Το γάλα συμβάλλει στην πρόσληψη αναγκαίων θρεπτικών συστατικών για τον οργανισμό όπως εκείνα του ασβεστίου, λακτόζης , αμινοξέων , βιταμινών , μεταλλικών αλάτων και διαφόρων άλλων που θα αναλυθούν παρακάτω. Η υγεία των γαλακτοφόρων ζώων και οι συνθήκες διαβίωσης αποτελεί πρωταρχική σημασία για την τελική ποιότητα του γάλακτος και των γαλακτοκομικών προϊόντων. Πέρα από τα οφέλη που προσφέρει το γάλα εγκυμονεί κινδύνους όπως φυσικούς, χημικούς και μικροβιολογικούς. Ένας από τους βασικότερους χημικούς κινδύνους είναι η παρουσία αφλατοξινών που ανήκει στις μυκοτοξίνες στα γαλακτοκομικά προϊόντα. Ειδικότερα ένα θέμα που απασχολεί τις βιομηχανίες γάλακτος είναι η παρουσία αφλατοξίνης Μ1, που προκύπτει από το μεταβολισμό της αφλατοξίνης Β1. Οι αφλατοξίνες προκαλούνται από διάφορα είδη μυκήτων, κυρίως το Aspergillus flavus and Aspergillus parasiticus και χαρακτηρίζονται απο τις πιο τοξικές ομάδες. Οι πιο σημαντικές είναι AFB1, AFB2, AFG1, AFG2, AFM1, AFM2. Τα τελευταία χρονιά το νομοθετικό πλαίσιο έχει μεριμνήσει για την παρουσία αφλατοξινών στα γαλακτοκομικά προϊόντα. Έχουν οριστεί ανώτατα όρια και κανονισμοί για την επιτρεπόμενη ποσότητα τους. Ωστόσο παραμένει ένα θέμα που ανησυχεί την δημόσια υγεία έχοντας επιβλαβείς επιπτώσεις τόσο στα συστατικά του γάλακτος όσο στην υγεία των ζώων και των ανθρώπων. Στην παρούσα εργασία γίνεται εκτενής αναφορά στις επιπτώσεις, στους τρόπους αντιμετώπισης καθώς και στους τρόπους ανίχνευσης αφλατοξινών.

description: Fluopyram, a pyridyl ethyl benzamide broad-spectrum fungicide and nematicide, used for the management of plant parasitic nematodes and soil-borne fungi, is recommended for use in crops like tomato, potato and tobacco. Fluopyram being a pesticide used for drenching soil, there is every possibility of it getting leached down with water, ultimately leading to contamination of waterbodies. An experiment was conducted to study the downward movement of fluopyram in laterite and red loam soils in Kerala, India. Fluopyram and fluopyram benzamide, each at150 µg, were loaded separately on top of the respective soil column and were eluted separately with 20, 40, 80 and 160 mL each of water equivalent to 50, 100, 200 and 400 mm rainfall. It was observed that 76.84% and 74.85% of fluopyram and 73.48% and 64.24% of fluopyram benzamide were confined to the top 0–10 cm soil with application of 20 mL water in laterite and red loam soil, respectively. More than 50% of fluopyram and fluopyram benzamide were detected in the top 0–10 cm layer of soil with the application of 40 and 80 mL water. With the application of 160 mL water, considerable reduction in the concentration of both compounds was observed and the residues moved beyond 30 cm. Leaching of residues was more in laterite soil than in red loam soil, and they are in direct relation to the volume of water applied and the residues moved beyond 30 cm depth with 160 mL water.
