description: In the present study, the antioxidant activity of sweet potato leaf polyphenols was measured, and the effect of different pH values (3.0, 5.0, 7.0, 8.0), temperatures (55, 65, 80, 100 °C) and light treatments on sweet potato leaf-polyphenols was investigated. Results showed that the ·O2− scavenging activity of sweet potato leaf polyphenols from cultivar Jishu No.04150 was 5.84 and 6.20 times of that of tea polyphenols and grape seed polyphenols, respectively at the concentration of 20μg/mL. The oxygen radical absorbance capacity was 1.28 and 1.27 times of that of tea polyphenols and grape seed polyphenols, respectively. Sweet potato leaf polyphenols dissolved in pH 5-7 solutions showed higher retention rates of antioxidant activity. Heat treatment at 50 and 65 °C and light treatment had little effects on sweet potato leaf polyphenols. In conclusion, sweet potato leaf polyphenols possessed high antioxidant activity and processing stability, having the potential to be a new type natural antioxidant.

description: Owing to their highly coherent emission and compact form factor, Brillouin lasers have been identified as a valuable asset for applications including portable atomic clocks, precision sensors, coherent microwave synthesis and energy-efficient approaches to coherent communications. While the fundamental emission linewidth of these lasers can be very narrow, noise within dielectric materials leads to drift in the carrier frequency, posing vexing challenges for applications requiring ultra-stable emission. A unified understanding of Brillouin laser performance may provide critical insights to reach new levels of frequency stability, however existing noise models focus on only one or a few key noise sources, and do not capture the thermo-optic drift in the laser frequency produced by thermal fluctuations or absorbed power. Here, we develop a coupled mode theory of Brillouin laser dynamics that accounts for dominant forms of noise in non-crystalline systems, capturing the salient features of the frequency and intensity noise for a variety of systems. As a result, theory and experiment can be directly compared to identify key sources of noise and the frequency bands they impact, revealing strategies to improve the performance of Brillouin lasers and pave the way for highly-coherent sources of light on a chip.

description: We determined abundances of Na and Zr in the atmospheres of 237 RGB stars in Galactic globular cluster (GGC) 47 Tuc (NGC 104), with a primary objective of investigating possible differences between the abundances of Zr in the first generation (1P) and second generation (2P) stars. For the abundance analysis, we used archival UVES/GIRAFFE spectra obtained during three different observing programmes. Abundances were determined from two Na I and three Zr I lines, using 1D hydrostatic ATLAS model atmospheres. The target stars for the abundance analysis were limited to those with 4200 $\leq$ $T_{\rm eff}$ $\leq$ 4800 K. This is the largest sample of GGC stars in which Na and Zr abundances have been studied so far. While our mean [Na/Fe] and [Zr/Fe] ratios agree well with those determined in the earlier studies, we find a weak but statistically significant correlation in the ${\rm [Zr/Fe]} - {\rm [Na/Fe]}$ plane. A comparison of the mean [Zr/Fe] abundance ratios in the 1P and 2P stars suggests a small but statistically significant Zr over-abundance in the 2P stars, $Δ{\rm [Zr/Fe]}_{\rm 2P-1P}\approx+0.06$ dex. Also, our analysis shows that stars enriched in both Zr and Na are more centrally concentrated. However, we find no correlation between their distance from the cluster centre and their full spatial velocity. While there may be some influence of CN line blends on the determined Zr abundances, it seems very unlikely that the detected Zr-Na correlation, for the slightly higher Zr abundances in the 2P stars, would be caused by the CN blending alone. The obtained results indicate that, in 47 Tuc, some amount of Zr should have been synthesised by the same polluters that enriched 2P stars with the light elements. Unfortunately, our data alone do not allow us to distinguish which of the two scenarios, or whether or not a combination of both, could have operated in this GGC.

description: The aim of this work is to put together two novel concepts from the theory of integrable billiards: billiard ordered games and confocal billiard books. Billiard books appeared recently in the work of Fomenko's school, in particular of V. Vedyushkina. These more complex billiard domains are obtained by gluing planar sets bounded by arcs of confocal conics along common edges. Such domains are used in this paper to construct the configuration space for billiard ordered games. We analyse dynamical and topological properties of the systems obtained in that way.

description: We improve the calculations of the elastic motion induced by the dark matter hits on the surface of the mirror equipped with the interferometer for gravitational waves detection. We focus on the discovery potential of such a dark matter signal on the third-generation European gravitational waves detector, the Einstein Telescope. By taking the thickness of mirror into account, more than one resonances are predicted in the sensitive regime of high frequency interferometer. When mass of dark matter is heavier than a few PeV or is highly boosted, the signal-to-noise ratio could exceed one, and Einstein Telescope should be about to detect this dark matter signal.

description: We investigate the evolutions of structural parameters, optical properties, and electronic structures of a van der Waals kagome semiconductor Pd$_{3}$P$_{2}$S$_{8}$ with Se doping. When the doping level of Se increases, the bandgaps of Pd$_{3}$P$_{2}$(S$_{1-x}$Se$_{x}$)$_{8}$ single crystals decrease gradually, accompanying with the expanded unit cells. The first-principles calculations show that there is a flat band (FB) near the Fermi level in bulk Pd$_{3}$P$_{2}$S$_{8}$. This FB mainly originates from the $d_{z^2}$-like orbitals of Pd atoms in the Pd kagome lattice, which have a finite interlayer electron hopping perpendicular to the PdS$_4$ square plane. The interlayer hopping can be reinforced with Se doping, inducing a stronger interlayer coupling via the chalcogen atoms at apical sites, which reduces the bandgap and enhances the cleavage energy. In contrast, the varnishing interlayer hopping in the two-dimensional limit results in the formation of ultra-FB in the monolayers of these compounds. The easy exfoliation and the existence of unique ultra-FB near $E_{\rm F}$ make Pd$_{3}$P$_{2}$(S$_{1-x}$Se$_{x}$)$_{8}$ a model system to explore the exotic physics of FB in 2D kagome lattice.

description: Recent global fit analyses of oscillation data show a preference for normal mass ordering (NMO) at 2.5$σ$ and provide 1.6$σ$ indications for lower $θ_{23}$ octant and leptonic CP violation. A high-precision measurement of $θ_{23}$ is pivotal to convert these hints into discoveries. In this work, we study in detail the capabilities of DUNE to establish the deviation from maximal $θ_{23}$ and to resolve its octant at high confidence levels. We exhibit the possible correlations and degeneracies among $\sin^2θ_{23}$, $Δm^2_{31}$, and $δ_{CP}$ in disappearance and appearance oscillation channels at the probability and event levels. Introducing for the first time, a bi-events plot in the plane of total $ν$ and $\barν$ disappearance events, we discuss the impact of $\sin^2θ_{23}$ - $Δm^2_{31}$ degeneracy in establishing non-maximal $θ_{23}$ and show how this degeneracy can be resolved by exploiting the spectral shape information in $ν$ and $\barν$ disappearance events. A 3$σ$ (5$σ$) determination of non-maximal $θ_{23}$ is possible in DUNE in total 7 years if $\sin^2θ_{23} \lesssim 0.465~(0.450)$ or $\sin^2θ_{23} \gtrsim 0.554~(0.572)$ for any value of $δ_{CP}$ and NMO. We study the individual contributions from appearance and disappearance channels, impact of systematic uncertainties and marginalization over oscillation parameters, importance of spectral analysis and data from both $ν$ and $\barν$ runs, while analyzing DUNE's sensitivity to establish non-maximal $θ_{23}$. DUNE can resolve the octant of $θ_{23}$ at 4.2$σ$ (5$σ$) using 7 (10) years of run assuming $\sin^2θ_{23}$ = 0.455, $δ_{CP}$ = $223^\circ$, and NMO. DUNE can improve the current relative 1$σ$ precision on $\sin^2θ_{23}$ ($Δm^2_{31}$) by a factor of 4.4 (2.8) using 7 years of run.

description: Giant radio quasars (GRQs) are radio-loud active galactic nuclei (AGNs), propelling megaparsec-scale jets. In order to understand GRQs and their properties, we have compiled all known GRQs ("the GRQ catalogue"), and a subset of small (size <700 kpc) radio quasars (SRQs) from the literature. In this process, we have found 10 new FR-II GRQs, in the redshift range of 0.66 < z < 1.72, which we include in the GRQ catalogue. Using the above samples, we have carried out a systematic comparative study of GRQs and SRQs, using optical and radio data. Our results show that the GRQs and SRQs statistically have similar spectral index and black hole mass distributions. However, SRQs have higher radio core power, core dominance factor, total radio power, jet kinetic power and Eddington ratio compared to GRQs. On the other hand, when compared to giant radio galaxies (GRGs), GRQs have higher black hole mass and Eddington ratio. The high core dominance factor of SRQs is an indicator of them lying closer to the line of sight than GRQs. We also find a correlation of the accretion disc luminosity with the radio core and jet power of GRQs, which provides evidence for disc-jet coupling. Lastly, we find the distributions of Eddington ratios of GRGs and GRQs to be bi-modal, similar to that found in small radio galaxies (SRGs) and SRQs, which indicate that size is not strongly dependent on the accretion state. Using all of these, we provide a basic model for the growth of SRQs to GRQs.

description: We analyze families of hybrid equations of state of cold QCD matter, which combine input from gauge/gravity duality and from various ab initio methods for nuclear matter at low density, and predict that all neutron stars are fully hadronic without quark matter cores. We focus on constraints from recent measurements by the NICER telescope on the radius and mass of the millisecond pulsar PSR J0740+6620. These results are found to be consistent with our approach: they set only mild constraints on the hybrid equations of state, and favor the most natural models which are relatively stiff at low density. Adding an upper bound on the maximal mass of neutron stars, as suggested by the analysis of the GW170817 neutron star merger event, tightens the constraints considerably. We discuss updated predictions on observables such as the transition density and latent heat of the nuclear to quark matter transition as well as the masses, radii, and tidal deformabilities of neutron stars.

description: The galactic cluster Westerlund 1 contains a rich population of evolved, massive stars, and a high binary fraction has been inferred from previous multiwavelength observations. We use multi-epoch spectroscopy of a large sample of early-type stars to identify new binaries and binary candidates in the cluster. VLT/FLAMES was used to obtain spectra of ~100 OB stars over a 14-month baseline in 2008 and 2009, supplemented with follow-up observations in 2011 and 2013, and we identify 20 new OB I--III binaries, a WN9h binary, and a WC9d binary, greatly increasing the number of directly confirmed binary systems in Westerlund 1, while 12 O9--9.5 Iab--III stars are identified as candidate binaries. The 173.9 day SB1 W1030 represents the first longer-period system identified in the cluster, while the determination of a 53.95 day period for W44/L makes it the first Wolf-Rayet binary in Westerlund 1 with a confirmed orbital period greater than ten days. Our results suggest the binary fraction in the OB population is at least 40%, and may be significantly higher. (Abridged)

description: We propose an extension of the Standard Model (SM) with a $U_{A'}(1)$ gauge invariant dark dector connected to the SM via a new portal -- the Stueckelberg portal, arising in the framework of dark photon $A'$ mass generation via Stueckelberg mechanism. This portal opens through the effective dim=5 operators constructed from the covariant term of the auxiliary Stueckelberg scalar field $σ$ providing flavor non-diagonal renormalizable couplings of both $σ$ and $A'$ to the SM fermions $ψ$. The Stueckelberg scalar plays a role of Goldstone boson in the generation of mass of the Dark Photon. Contrary to the conventional kinetic mixing portal, in our scenario flavor diagonal $A'$-$ψ$ couplings are not proportional to the fermion charges and are, in general, flavor nondiagonal. These features drastically change the phenomenology of dark photon $A'$ relaxing or avoiding some previously established experimental constraints. We focus on the phenomenology of the described scenario of the Stueckelberg portal in the lepton sector and analyze the contribution of the dark sector fields $A'$ to the anomalous magnetic moment of muon $(g-2)_μ$, lepton flavor violating decays $l_{i}\to l_{k}γ$ and $μ-e$ conversion in nuclei. We obtain limits on the model parameters from the existing data on the corresponding observables.

description: In recent years, there has been increased interest in examining alternative polymers for the conservation of archaeological artefacts, particularly waterlogged timbers, providing better, renewable, greener alternatives to poly(ethylene glycol) (PEG). The degradation of PEG consolidants in the timbers of the sixteenth century warship Mary Rose has been examined and the rheological and thermal properties of PEG have been compared with its monomethyl and dimethyl ethers and several polysaccharide consolidants (chitosan, guar, and 2-hydroxyethyl cellulose) in order to evaluate their potential as alternative consolidants for the conservation of waterlogged wooden artefacts. Additionally, the effect of the polymers on the archaeological wood was characterised by thermogravimetric analysis and solid-state nuclear magnetic resonance spectroscopy. The results suggest that the future of conservation technologies lies with polysaccharide consolidant materials, which show enhanced compatibility with wooden artefacts with no detectable side effects while also being cheap, with extremely low toxicity, renewable, and sustainably resourced.

description: Objectives In Finland, a dental subsidization reform, implemented in 2001–2002, abolished age restrictions on subsidized dental care. The aim of this study was to investigate income-related inequality in the perceived oral health and its determinants among adult Finns before and after the reform. Materials and methods Three identical cross-sectional nationally representative postal surveys, concerning perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2157), in 2004 (n = 1814) and in 2007 (n = 1671). Three measures of perceived oral health were used: toothache or oral discomfort during the past 12 months, current need for dental care and self-reported oral health status. Concentration index was used to analyse the income-related inequalities. Its decomposition was used to study factors related to the inequalities. Results The proportion of respondents reporting need for dental care decreased from 2001 to 2007, while no changes were seen in reports of toothache or self-reported oral health status. Income-related inequalities in reports of toothache and perceived need for care widened, while the inequality in self-reported oral health remained stable. Most of the inequalities were related to income itself, perceived general health and the time since the last visit to dental care. Conclusions It seems that the income-related inequalities in perceived oral health remained or even widened after the reform.

description: In our previous work \cite{PTA2} we calculated the overlap reduction function for the tensor polarization without employing the short wavelength approximation, this was done by obtaining a power series of nested sums which is valid for all gravitational wave frequencies and pulsar distances. In this work we generalize the power-series expansion method to vector and scalar polarizations. We have compared our expression for the breathing and vector modes with previous literature. We present for the first time analytic expressions for the overlap reduction function of the longitudinal mode for all angles between the pulsar pairs.

description: Using data from the Sloan Digital Sky Survey we study correlations between directions of galaxy angular momenta determined from images of spiral galaxies and various observables derived from the reconstructed initial conditions. We find an apparent systematic effect consistent with galaxy-orientation-dependent selection function. After restricting our attention to the brightest half of the galaxies where this systematic effect is presumed to be absent, we find hints of excess/deficit correlation for two observables. Interestingly, tidal torque theory predicts excess/deficit correlation in exactly these two observables. After correcting for the redshift space distortions, the significance of these correlations drops below 3$σ$ threshold. We do not find any other systematic issues, but a thorough systematic analysis goes beyond the scope of this work.

description: There are multipartite entangled states in many-body systems which may be potential resources in various quantum applications. There are lots of methods to witness specific entangled systems. However, no efficient method is available to explore many-body systems without multipartite entanglement. It may provide necessary restrictions for experimental preparations of multipartite entanglement. Our goal is to solve this problem for spin systems. The maximal effective velocity with propagation of information is bounded in quantum spin systems with short-range interactions from Lieb-Robinson's inequalities. This implies two clustering theorems for ground states and thermal states. With these propagation relations, we show that both the gapped ground state and thermal state at an upper-bounded inverse temperature have no genuine multipartite nonlocality when disjoint regions are far away from each other. The present $n$-particle system shows only biseparable quantum correlations when the propagation relations show exponential decay. Similar result holds for spin systems with product states as initial states. These results show interesting features of quantum many-body systems with exponential decay of correlations.

description: A list of 25 species of the genus Eumerus Meigen (Diptera: Syrphidae) from the eastern Mediterranean islands is presented. Descriptions are given for three new species: Eumerus aurofinis Grković, Vujić & Radenković n. sp. from Lesvos, Samos, Rhodes islands (Greece) and Bozdağ mountain (Turkey), E. torsicus Grković & Vujić n. sp. from Chios Island (Greece) and Cyprus; E. crassus Grković, Vujić & Radenković n. sp. from Lesvos Island (Greece). In addition to classical morphological characters, mitochondrial COI barcode sequences were generated for several specimens of two available taxa. The status of Eumerus alpinus Rondani, 1857 is revised, and the taxon is resurrected from synonymy of E. olivaceus Loew, 1848. The zoogeographical significance of the described endemic taxa to the biodiversity of the Aegean islands is discussed.

Mapping the metastability of Lennard-Jones clusters by the maximum vibrational frequency

description: We study the structure-stability relationship of the Lennard-Jones (LJ) clusters from a point of view of vibrations. By assuming the size up to $N=1610$, we demonstrate that the $N$-dependence of the maximum vibrational frequency reflects the geometry of the core (the interior of cluster) that will determine the overall geometry of the cluster. This allows us to identify the formation of non-icosahedral structures for $N\le 150$, the vacancy formation at the core for $N\ge 752$, and the transition from icosahedral to decahedral structures at $N = 1034$. We apply the maximum frequency analysis to classify metastable clusters for $19\le N \le 39$, where transformation pathways between different structures are visualized, and the energy barrier height is estimated simultaneously.

Low Temperature Steam Reforming of Methanol: Rationalising the Behaviour of Cu/Zn/Ga Oxide Catalysts

description: Abstract - 43%Cu-ZnGaOx is identified as a new, high activity catalyst for the low temperature steam reforming of methanol, and its behaviour rationalised in terms of Cu surface area, catalyst structure and metal-support interactions. TPR is used to investigate metal reducibility; N2O chemisorption to determine specific metal surface area, dispersion and particle size; XRD to investigate the catalyst structure; AC impedance spectroscopy to measure oxygen mobility, and EPR spectroscopy to probe the electronic environment of Cu2+ species. The high activity of Cu/Zn/Ga systems is related to the formation of a non-stoichiometric cubic spinel phase containing interstitial Cu+ ions which are easily reducible below 200oC and highly dispersed, leading to enhanced Cu surface area, which in turn improves catalytic activity. Oxygen vacancies are proposed to play an important role in promoting SRM at the metal-support interface, but also promoting CO production via reverse WGS reaction in the bulk support. Therefore by simultaneously maximising the Cu dispersion whilst minimising the availability of O-vacancies in the bulk support, the activity of a catalyst to SRM can be greatly enhanced, with little or no CO formation. 43%Cu-ZnGaOx is shown to achieve this balance via its stabilisation of the cubic NSS phase due to the presence of Zn2+, but also via the presence of Ga3+ which reduces the O-mobility in the support sufficiently to suppress CO formation.

Radial overlap correction to superallowed $0^+ \to 0^+$ nuclear $β$ decays using the shell model with Hartree-Fock radial wave functions

description: The radial overlap correction, $δ_{RO}$ is re-examined for 30 superallowed $β$ decays using the shell model with Hartree-Fock (HF) radial wave functions. Our calculation is based on the Skyrme interaction including Coulomb, Charge-Symmetry-Breaking (CSB) and Charge-Independence-Breaking (CIB) terms. The corrections due to the gradient of charge density, vacuum polarization, Coulomb spin-orbit and finite size of nucleons are also considered. To avoid the spurious isospin mixing, the local equivalent potential is constructed from the solution of a HF calculation for the $Z=N$ nucleus without charge-dependent forces. The obtained mean field is solved non-iteratively for the parent and daughter nuclei. It turns out that the CIB term has no significant impact on $δ_{RO}$. On the other hand, the CSB term makes $δ_{RO}$ increasing between 10 and 30%. The gradient density leads to a further increase of $δ_{RO}$ between 2 and 14%, while other electromagnetic corrections are negligible. The effect of the suppression of isospin spuriosity is somewhat complicated. In general, it produces a larger $δ_{RO}$ value, however there are few cases for which $δ_{RO}$ is mostly unaffected or even reduced, especially the light even-even emitters. All these improvements partly explain the long-standing discrepancy between the correction values obtained with Woods-Saxon (WS) and HF radial wave functions. Nevertheless, the remaining discrepancy is still significant, except for the emitters with $A\le 26$. In addition, the staggering presented on the results obtained with the WS potential are not well reproduced by our calculations. This subsequently leads to a large difference in the predicted mirror $ft$ ratios. These problems might relate to the errors of the calculated radii as well as correlation in the data used for constraining the asymptotic radial wave functions.

Viscous absorption of ultra-high-frequency gravitons

description: The high-frequency gravitons can be absorbed by the first and second viscosities of the post-inflationary plasma as the corresponding wavelengths reenter the Hubble radius prior to big-bang nucleosynthesis. When the total sound speed of the medium is stiffer than radiation the rate of expansion still exceeds the shear rate but the bulk viscosity is not negligible. Depending on the value of the entropy density at the end of inflation the spectral energy density of the relic gravitons gets modified in comparison with the inviscid result when the frequency ranges between the kHz band and the GHz region. In the nHz domain the spectrum inherits a known suppression due to neutrino free-streaming but also a marginal spike potentially caused by a sudden outbreak of the bulk viscosity around the quark-hadron phase transition, as suggested by the hadron spectra produced in the collisions of heavy ions.

EMOTIONS AS CONSEPTS IN COGNITIVE LINGUISTICS
Creators: name: Ubaydullayeva, Dilafruz
Publisher: name: Zenodo
Year: 2024

description: This work aims to present a novel perspective on emotion categories in cognitive linguistics (see to Kövecses 1986, 1990, 2000 for the "old" view). The premise that conceptual metaphors are multidimensional structures and the addition of a reformulated understanding of context to CMT (see Kövecses 2020) are the two modifications to "standard" conceptual metaphor theory (CMT) that the new perspective builds upon. These two modifications to the theory allow us to view emotion concepts as multidimensional metaphorical frameworks enmeshed in a multitude of contextual details.
