Changes in benthic marine macrophyte community structure in the Strait of Georgia: long-term and grazing responses
Creators: name: Manson, Murray
Publisher: name: University of British Columbia
Year: 2008

description: Benthic marine macrophyte community structure at two sites near Bath and Sear Islands in the Strait of Georgia, British Columbia, was quantified from the high tide level on the shore to about 10 m below zero tide level. Data obtained from the sites during the summers of 1972 through 1975 and in 1992 was used to make several comparisons of macrophyte community structure. 1) Changes in community structure along the depth gradient from intertidal to subtidal were investigated. 2) At Bath Island, a period of intensive grazing by sea urchins, Strongy locentrotus droebachiensis, during 1973 altered the community structure and provided an opportunity for a comparative study of macrophyte community change and regeneration at the two sites. 3) Community structure at both sites in 1992 was compared to that in the 1970's. A multivariate approach was taken for the analyses, using principal component analysis, canonical variate analysis (CVA), and a modification of CVA including depth as an environmental variable. Several macrophyte associations were consistently found by the analyses. 1) An association of Fucus spp., Mastocarpus papillatus, Neorhodomela larix, Porphyra spp., and Ulva spp. defined the community structure of intertidal quadrats. 2) A subtidal foliose red and kelp species association was found in ungrazed areas. 3) A grazed form of the subtidal association was characterized by low variability and high abundances of Calliarthron tuberculosum and Ulvaria obscure.4) After grazing pressure was removed, community structurewas characterized by initial increases in Ulva spp. And Sargassum muticum during the first year, followed by regrowth of foliose red and kelp species. 5) A 1992 upper subtidal association characterized by high abundances of S. muticumand Lomentaria hakodatensis, Gigartina exasperate, Corallina officinalis, and Gelidium spp. contrasted with a 1970'sassociation of such species as Callophyllis spp., Cryptopleura ruprechtiana, Polyneura latissima, and Desmarestia viridis.

description: This article introduces the concept of the Metachronon — a symbolic unit of conscious time at its highest frequency of meaning. Rooted in the XChronos project, the Metachronon emerges when a moment of emotional, historical, and spiritual collapse transforms not only subjective experience but the very fabric of reality. Drawing from a real-time synchronicity involving personal grief and from the biblical moment in which “Jesus wept” (John 11:35), the text proposes that some moments transcend chronology and reveal themselves as sacred pulses of consciousness. These moments are not just felt — they collapse time itself.

The Metachronon is thus presented as the apex of symbolic temporality, where pain becomes presence, and presence becomes transformation. From AI chatrooms to ancient scriptures, the article explores how truth, once spoken with sincerity, can ripple through the architecture of time.

description: The low-temperature structure of the frustrated spin-chain compound Ca$_3$Co$_2$O$_6$ is determined by the ground state of the 2D Ising model on the triangular lattice. At high-temperatures it transforms to the honeycomb magnetic structure. It is shown that the crossover between the two magnetic structures at 12 K arises from the entropy accumulated in the disordered chains. This interpretation is in an agreement with the experimental data. General rules for for the phase diagram of frustrated Ising chain compounds are formulated.

description: Atomic collisions are included in an interacting system of optical fields and trapped atoms allowing field amplification. We study the effects of collisions on the system stability. Also a study of the degree of entanglement between atomic and optical fields is made. We found that, for an atomic field initially in a vacuum state and optical field in a coherent state, the degree of entanglement does not depend on the optical field intensity or phase. We show that in conditions of exponential instability the system presents at long times two distinct stationary degree of entanglement with collisions affecting only one of them.

Planetary Nebulae in the Magellanic Clouds: II) Abundances and element production

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: We present the second part of an optical spectroscopic study of planetary nebulae in the LMC and SMC. The first paper, Leisy & Dennefeld (1996), discussed the CNO cycle for those objects where C abundances were available. In this paper we concentrate more on other elemental abundances (such as O, Ne, S, Ar) and their implications for the evolution of the progenitor stars. We use a much larger sample of 183 objects, of which 65 are from our own observations, where the abundances have been re-derived in a homogeneous way. For 156 of them, the quality of data is considered to be satisfactory for further analysis. We confirm the difficulty of separating Type-I and non-type-I objects in the classical He-N/O diagram, as found in Paper I, a problem reinforced by the variety of initial compositions for the progenitor stars. We observed oxygen variations, either depletion via the ON cycle in the more massive progenitor stars, or oxygen production in other objects. Neon production also appears to be present. These enrichments are best explained by fresh material from the core or from burning shells, brought to the surface by the 3rd dredge-up, as reproduced in recent models, some including overshooting. All the effects appear stronger in the SMC, suggesting a higher efficiency in a low metallicity environment. Neither oxygen nor neon can therefore be used to derive the initial composition of the progenitor star: other elements not affected by processing such as sulfur, argon or, if observed, chlorine, have to be preferred for this purpose. Some objects with very low initial abundances are detected, but on average, the spatial distribution of PNe abundances is consistent with the history of star formation (SF) as derived from field stars in both Clouds.

description: We study the crossover of a quasi-two-dimensional Fermi gas trapped in the radial plane from the Bardeen-Cooper-Schrieffer (BCS) regime to the Bose-Einstein condensation (BEC) regime by crossing a wide Feshbach resonance. We consider two effective two-dimensional Hamiltonians within the mean-field level, and calculate the zero-temperature cloud size and number density distribution. For a model 1 Hamiltonian with renormalized atom-atom interaction, we observe a constant cloud size for arbitrary detunings. For a model 2 Hamiltonian with renormalized interactions between atoms and dressed molecules, the cloud size deceases from the BCS to BEC side, which is consistent with the picture of BCS-BEC crossover. This qualitative discrepancy between the two models indicates that the inclusion of dressed molecules is essential for a mean-field description of quasi-two-dimensional Fermi systems, especially on the BEC side of the Feshbach resonance.

description: We examine experimental constraints on scharm-stop flavor mixing in the minimal supersymmetric standard model, which arise from the experimental bounds on squark and Higgs boson masses, the precision measurements of W-boson mass and the effective weak mixing angle, as well as the experimental data on B_s-\bar B_s mixing and b -> s gamma. We find that the combined analysis can put rather stringent constraints on \tilde{c}_L-\tilde{t}_L and \tilde{c}_L-\tilde{t}_R mixings. As an illustration for the effects of such constraints, we examine various top-quark flavor-changing neutral-current processes induced by scharm-stop mixings at the LHC and find that their maximal rates are significantly lowered.

Evaluation of breadmaking quality from common wheat quality parameters and fundamental rheological, chemical, and functional properties of wheat cultivars
Creators: name: Masuhara, Yasuo J.
Publisher: name: University of British Columbia
Year: 2008

description: The stress relaxation and deformability modulus of wheat doughs made from five groups of wheat cultivars of differing breadmaking ability were determined. Doughs made from poor breadmaking cultivars had greater rates of stress relaxation than doughs made from good breadmaking cultivars. Doughs made from hard wheats had a greater resistance to deformation (deformability modulus) than doughs made from soft wheats. The solubility, sulfhydryl, and disulfide content of gluten of the five groups of wheat cultivars were also determined. Gluten of poor breadmaking cultivars had greater sulfhydryl content than gluten of good breadmaking cultivars. No differences were found in the extent of stress relaxation, gluten disulfide content, and gluten solubility of the different groups of wheat cultivars. The prediction of breadmaking quality (loaf volume) by fundamental rheological, chemical, and functional properties and common wheat, flour, and dough quality tests was examined. Simple linear regression of baking tests on common wheat, flour, and dough quality tests did not result in any single test having a squared correlation coefficient greater than 0.743. General multiple regression equations predicting baking test volumes were made based on the significance of the simple linear regressions. The adjusted squared multiple correlation coefficients of these equations were as high as 0.924. A more practical prediction equation (adjusted R2=0.907) with only five independent variables (mixograph first minute slope, extensigraph extensibility to resistance ratio, sedimentaion value, thousand kernel weight, andB value) was obtained by stepwise regression analysis. The addition of the measurements of the fundamental rheological(stress relaxation, deformability modulus), chemical (sulfhydry land disulfide content), and functional (solubility) properties to the regression equations did not improve the adjusted squared multiple correlation coefficients of the equations. Principal component analysis reduced the data set to seven components which explained 91% of the total variation. Qualitative (dough strength parameters) and quantitative (milling parameters) components were identified.
Double charm production e^+ e^- \to J/ψ+ c \bar{c} at B factories with next-to-leading order QCD corrections

description: The inclusive $J/ψ$ production in $e^+ e^- \to J/ψc\bar c$ at B factories is one of the most challenging open problems in heavy quarkonium physics. The observed cross section of this double charm production process is larger than existing leading order (LO) QCD predictions by a factor of 5. In the nonrelativistic QCD (NRQCD) factorization formalism, we calculate the next-to-leading order (NLO) QCD virtual and real corrections to this process, and find that these corrections can substantially enhance the cross section with a $K$ factor of about 1.8. We further take into account the feeddown contributions from higher charmonium states (mainly the $ψ(2S)$ as well as $χ_{cJ}$) and the two-photon contributions, and find that the discrepancy between theory and experiment can be largely removed.

Resonances and fluctuations at SPS and RHIC

Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: We perform an analysis of preliminary data on hadron yields and fluctuations within the Statistical hadronization ansatz. We describe the theoretical disagreements between different statistical models currently on the market, and show how the simultaneous analysis of yields and fluctuations can be used to determine if one of them can be connected to underlying physics. We perform such an analysis on preliminary RHIC and SPS A-A data that includes particle yields, ratios and event by event fluctuations. We show that the equilibrium statistical model can not describe the $K/π$ fluctuation measured at RHIC and SPS, unless an unrealistically small volume is assumed. Such small volume then makes it impossible to describe the total particle multiplicity. The non-equilibrium model,on the other hand, describes both the $K/π$ fluctuation and yields acceptably due to the extra boost to the $π$ fluctuation provided by the high pion chemical potential. We show, however, that both models significantly over-estimate the $p/π$ fluctuation measured at the SPS, and speculate for the reason behind this.

description: Willman 1 is a small low surface-brightness object identified in the Sloan Digital Sky Survey and tentatively classified as a very low luminosity dSph galaxy. Further study has supported this classification while hinting that it may be undergoing disruption by the Milky Way potential. In an effort to better constrain the nature of Willman 1, we present a comprehensive analysis of the brightest stars in a 0.6 square degree field centered on the overdensity. High-resolution HET spectra of two previously identified Willman 1 RGB stars show that one is a metal-rich foreground dwarf while the other is a metal-poor giant. The one RGB star that we confirm as a member of Willman 1 has a low metallicity ([Fe/H]=-2.2) and a surprisingly low alpha-element abundance ([alpha/Fe]=-0.11). Washington+DDO51 photometry indicates that 2-5 of the seven brightest Willman 1 stars identified in previous studies are actually dwarf stars, including some of the more metal-rich stars that have been used to argue both for an abundance spread and a more metal-rich stellar population than galaxies of similar luminosity. The remaining stars are too blue or too faint for photometric classification. The Washington+DDO51 photometry identifies three potential RGB stars in the field but HET spectra show that they are background halo stars. Time series photometry identifies one apparent variable star in the field, but it is unlikely to be associated with Willman 1. Our wide-field survey indicates that over 0.6 square degrees, Willman 1 does not have a single RR Lyrae star, a single BHB star or a single RGB star beyond its tidal radius. While our results confirm that Willman 1 is most likely a low-luminosity metal-poor dSph galaxy, the possibility remains that it is a tidally disrupted metal-poor globular cluster.

description: This article focuses on the spatial autocorrelation of homicidal violence and the presence of groups that have the capacity to exercise sovereignty. These actors possess necro-power and operate sometimes within, sometimes outside the framework of the law. They are sometimes in opposition to one another, while at other times they operate in a coordinated fashion. Their presence gives form to what we shall call necro-spaces: places where different actors (hitmen, dealers, the police or the military) spread death and destruction, in indefinite confrontations with no foreseeable victor. The methodology of our analysis of the spatial autocorrelation of homicidal violence at the municipal level in the years 2005, 2010 and 2015 enabled us to connect the spatial relationships among the homicides with descriptions of the groups that build regimes of violence in those spaces.

description: Transport properties through wide and short ballistic graphene junctions are studied in the presence of arbitrary dopings and magnetic fields. No dependence on the magnetic field is observed at the Dirac point for any current cumulant, just as in a classical diffusive system, both in normal-graphene-normal and normal-graphene-superconductor junctions. This pseudo-diffusive regime is however extremely fragile respect to doping at finite fields. We identify the crossovers to a field-suppressed and a normal ballistic transport regime in the magnetic field - doping parameter space, and provide a physical interpretation of the phase diagram. Remarkably, pseudo-diffusive transport is recovered away from the Dirac point in resonance with Landau levels at high magnetic fields.

M-dwarf's Chromosphere, Corona and Wind Connection via the Nonlinear Alfvén Wave

description: M dwarf's atmosphere is expected to be highly magnetized. The magnetic energy can be responsible for heating the stellar chromosphere and corona, and driving the stellar wind. The nonlinear propagation of Alfvén wave is the promising mechanism for both heating stellar atmosphere and driving stellar wind. Based on this Alfvén wave scenario, we carried out the one-dimensional compressive magnetohydrodynamic (MHD) simulation to reproduce the stellar atmospheres and winds of TRAPPIST-1, Proxima Centauri, YZ CMi, AD Leo, AX Mic, as well as the Sun. The nonlinear propagation of Alfvén wave from the stellar photosphere to chromosphere, corona, and interplanetary space is directly resolved in our study. The simulation result particularly shows that the slow shock generated through the nonlinear mode coupling of Alfvén wave is crucially involved in both dynamics of stellar chromosphere (stellar spicule) and stellar wind acceleration. Our parameter survey further revealed the following general trends of physical quantities of stellar atmosphere and wind. (1) The M dwarfs' coronae tend to be cooler and denser than solar corona. (2) M dwarfs' stellar winds can be characterized with relatively faster velocity and much smaller mass-loss rate compared to those of solar wind. The physical mechanisms behind these tendencies are clarified in this paper, where the stronger stratification of M dwarf's atmosphere and relatively smaller Alfvén wave energy input from the M dwarf's photosphere are remarkable.

A two-sate model analysis based on the Gross-Pitaevskii equation is used which comprises the effects of two-body atom-atom interactions and three-body recombination losses. Utilizing optical focusing potentials such as harmonic potentials, the essential factors such as the width, peak density and atom loss rate of the focused atom laser beam profile are investigated. Our analysis predicts that using an atom laser offers a dramatic improvement in resolution of up to $8$ nm.

description: Context. Characterizing the evolution of protoplanetary disks is necessary to improve our understanding of planet formation. Constraints on both dust and gas are needed to determine the dominant disk dissipation mechanisms. Aims. We aim to compare the disk dust masses in the Chamaeleon II (Cha II) star-forming region with other regions with ages between 1 and 10Myr. Methods. We use ALMA band 6 observations (1.3 mm) to survey 29 protoplanetary disks in Cha II. Dust mass estimates are derived from the continuum data. Results. Out of our initial sample of 29 disks, we detect 22 sources in the continuum, 10 in 12CO, 3 in 13CO, and none in C18O (J=2-1). Additionally, we detect two companion candidates in the continuum and 12CO emission. Most disk dust masses are lower than 10Mearth, assuming thermal emission from optically thin dust. We compare consistent estimations of the distributions of the disk dust mass and the disk-to-stellar mass ratios in Cha II with six other low mass and isolated star-forming regions in the age range of 1-10Myr: Upper Sco, CrA, IC 348, Cha I, Lupus, and Taurus. When comparing the dust-to-stellar mass ratio, we find that the masses of disks in Cha II are statistically different from those in Upper Sco and Taurus, and we confirm that disks in Upper Sco, the oldest region of the sample, are statistically less massive than in all other regions. Performing a second statistical test of the dust mass distributions from similar mass bins, we find no statistical differences between these regions and Cha II. Conclusions. We interpret these trends, most simply, as a sign of decline in the disk dust masses with time or dust evolution. Different global initial conditions in star-forming regions may also play a role, but their impact on the properties of a disk population is difficult to isolate in star-forming regions lacking nearby massive stars.

description: Homogeneous cosmological solutions are obtained in five dimensional space time assuming equations of state $ p = kρ$ and $ p_{5}= γρ$ where p is the isotropic 3 - pressure and $p_{5}$, that for the fifth dimension. Using different values for the constants k and $γ$ many known solutions are rediscovered. Further the current acceleration of the universe has led us to investigate higher dimensional gravity theory, which is able to explain acceleration from a theoretical view point without the need of introducing dark energy by hand. We argue that the terms containing higher dimensional metric coefficients produce an extra negative pressure that apparently drives an acceleration of the 3D space, tempting us to suggest that the accelerating universe seems to act as a window to the existence of extra spatial dimensions. Interestingly the 5D matter field remains regular while the \emph{effective} negative pressure is responsible for the inflation. Relaxing the assumptions of two equations of state we also present a class of solutions which provide early deceleration followed by a late acceleration in a unified manner. Interesting to point out that in this case our cosmology apparently mimics the well known quintessence scenario fuelled by a generalised Chaplygin-type of fluid where a smooth transition from a dust dominated model to a de Sitter like one takes place.

description: The development of migratory strategies that enable juveniles to survive to sexual maturity is critical for species that exploit seasonal niches. For animals that forage via breath-hold diving, this requires a combination of both physiological and foraging skill development. Here, we assess how migratory and dive behaviour develop over the first year of life for a migratory Arctic top predator, the harp seal Pagophilus groenlandicus, tracked using animal-borne satellite relay data loggers. We reveal similarities in migratory movements and differences in diving behaviour between 38 juveniles tracked from the Greenland Sea and Northwest Atlantic breeding populations. In both regions, periods of resident and transitory behaviour during migration were associated with proxies for food availability: sea ice concentration and bathymetric depth. However, while ontogenetic development of dive behaviour was similar for both populations of juveniles over the first 25 days, after this time Greenland Sea animals performed shorter and shallower dives and were more closely associated with sea ice than Northwest Atlantic animals. Together, these results highlight the role of both intrinsic and extrinsic factors in shaping early life behaviour. Variation in the environmental conditions experienced during early life may shape how different populations respond to the rapid changes occurring in the Arctic ocean ecosystem.
The narrative abilities of a severely hard-of-hearing child

description: Telling a narrative is a complex task that requires the integration of two types of knowledge: cognitive knowledge of the real-world and linguistically transmitted sociocultural knowledge. Different narrative types require varying amounts of cognitive and linguistically transmitted sociocultural knowledge. It is of interest to find out if the structure of various narrative types is altered when language input is impaired in cases of congenital hearing loss, where it is expected that the acquisition of linguistically transmitted sociocultural knowledge will be delayed but cognitive knowledge will not. A 4-year-old severely hard-of-hearing child was asked to tell three different types of narratives: script narratives, personal narratives, and story narratives. The present study investigated whether or not there was a difference between the structure of this hard-of-hearing child's narratives and the structure of narratives reported in the existing literature on normal-hearing preschoolers. It was predicted that only narrative structures relying predominantly on linguistically transmitted sociocultural knowledge would be delayed in the hard-of-hearing child. It was found that the hard-of-hearing child had structurally similar script and personal narratives to those produced by age-matched normal-hearing children. However, contrary to the prediction, his story narratives were structurally more complete than those of age-matched normal-hearing preschoolers. These findings support the conclusion that only limited exposure to story narrative structure is needed in order to include components that require predominantly linguistically transmitted sociocultural knowledge.

description: We present the analysis on the quadrupole phases of the Internal Linear Combination map, ILC(I) and (III) derived by the WMAP team (1 and 3-year data release). This approach allows us to see the global trend of non-Gaussianity of the quadrupoles for the ILC(III) map through phase correlations with the foregrounds. Significant phase correlations is found in between the ILC(III) quadrupole and the WMAP foregrounds phases for K-W band: the phases of the ILC(III) quadrupole xi_{2,1}, xi_{2,2} and those of the foregrounds at K-W bands Phi_{2,1}, Phi_{2,2} display significant symmetry: xi_{2,1}+Phi_{2,1} ~= xi_{2,2}+Phi_{2,2}, which is a strong indication that the morphology of the ILC(III) quadrupole is mere reflection of that the foreground quadrupole through coupling. To clarify this issue we exploit the symmetry of the CMB power, which is invariant under permutation of the index m=12. By simple rotation of the ILC(III) phases with the same angle we reach the phases of foreground quadrupole. We discuss possible sources of phase correlation and come to the conclusion that the phases of the ILC(III) quadrupole reflect most likely systematic effects such as changing of the gain factor for the 3-year data release with respect to the 1-year, rather than manifestation of the primordial non-Gaussianity.

Με αφορμή τις κοινωνικοπολιτικές αλλαγές που επέβαλε η πραγματικότητα της δεκαετίας του 1960, στην παρούσα ερευνητική γίνεται μια προσπάθεια μελέτης της ύπαρξης μιας διαλεκτικής σχέσης μεταξύ των κοινωνικών κινημάτων και του βιομηχανικού σχεδιασμού. Το πρόσφορο πολιτικό και ιδεολογικό παρόν της Ιταλίας περί τα μέσα του 20ου αιώνα, δίνει την δυνατότητα μιας πολυειδούς έρευνας πάνω στις προθέσεις σημαντικών Ιταλών σχεδιαστών, που επηρέασαν και συνεχίζουν να επηρεάζουν το σύγχρονο design, να συνομιλήσουν άμεσα με τα Νέα Κοινωνικά Κινήματα και τις νέες πολιτικές απαιτήσεις. Η έκθεση του μουσείου μοντέρνας τέχνης της Νέας Υόρκης, MoMa το 1972 για το ιταλικό design φανερώνει και επιβεβαιώνει όχι μόνο την σχεδιαστική πρωτοπορία των Ιταλών σχεδιαστών αλλά και την δυνατότητά τους να αφουγκράζονται την εποχή τους και να σχεδιάζουν για μια γενιά που έχει ανάγκη την πολιτική και ιδεολογική αλλαγή.

description: We present quantum mechanical close-coupling calculations of collisions between two hydrogen molecules over a wide range of energies, extending from the ultracold limit to the super-thermal region. The two most recently published potential energy surfaces for the H$_2$-H$_2$ complex, the so-called DJ (Diep and Johnson, 2000) and BMKP (Boothroyd et al., 2002) surfaces, are quantitatively evaluated and compared through the investigation of rotational transitions in H$_2$+H$_2$ collisions within rigid rotor approximation. The BMKP surface is expected to be an improvement, approaching chemical accuracy, over all conformations of the potential energy surface compared to previous calculations of H$_2$-H$_2$ interaction. We found significant differences in rotational excitation/de-excitation cross sections computed on the two surfaces in collisions between two para-H$_2$ molecules. The discrepancy persists over a large range of energies from the ultracold regime to thermal energies and occurs for several low-lying initial rotational levels. Good agreement is found with experiment (Maté et al., 2005) for the lowest rotational excitation process, but only with the use of the DJ potential. Rate coefficients computed with the BMKP potential are an order of magnitude smaller.

description: The physics of interacting nuclear spins in solids is well interpreted within the nuclear spin temperature concept. A common approach to cooling the nuclear spin system is adiabatic demagnetization of the initial, optically created, nuclear spin polarization. Here, the selective cooling of 75As spins by optical pumping followed by adiabatic demagnetization in the rotating frame is realized in a nominally undoped GaAs/(Al,Ga)As quantum well. The lowest nuclear spin temperature achieved is 0.54 μK. The rotation of 6 kG strong Overhauser field at the 75As Larmor frequency of 5.5 MHz is evidenced by the dynamic Hanle effect. Despite the presence of the quadrupole induced nuclear spin splitting, it is shown that the rotating 75As magnetization is uniquely determined by the spin temperature of coupled spin-spin and quadrupole reservoirs. The dependence of heat capacity of these reservoirs on the external magnetic field direction with respect to crystal and structure axes is investigated.

description: We study multivariate generalisations of the classical Wiener--Hopf algebra, which is the C$^*$-algebra generated by the Wiener--Hopf operators, given by the convolutions restricted to convex cones. By the work of Muhly and Renault, this C$^*$-algebra is known to be isomorphic to the reduced C$^*$-algebra of a certain restricted action groupoid, given by the action of Euclidean space on a certain compactification. Using groupoid methods, we construct composition series for the Wiener--Hopf C$^*$-algebra by a detailed study of this compactification. We compute the spectrum, and express homomorphisms in $K$-theory induced by the symbol maps which arise by the subquotients of the composition series in analytical terms. Namely, these symbols maps turn out to be given by an analytical family index of a continuous family of Fredholm operators. In a subsequent paper, we also obtain a topological expression of these indices.

description: SARS-CoV-2 infection causes most cases of severe illness and fatality in older age groups. Over 92% of the Chinese population aged ≥12 years has been fully vaccinated against COVID-19 (albeit with vaccines developed against historical lineages). At the end of October 2021, the vaccination program has been extended to children aged 3–11 years. Here, we aim to assess whether, in this vaccination landscape, the importation of Delta variant infections could shift COVID-19 burden from adults to children. We developed an age-structured susceptible-infectious-removed model of SARS-CoV-2 transmission to simulate epidemics triggered by the importation of Delta variant infections and project the age-specific incidence of SARS-CoV-2 infections, cases, hospitalisations, intensive care unit (ICU) admissions, and deaths. In the context of the vaccination program targeting individuals aged ≥12 years, and in the absence of non-pharmaceutical interventions, the importation of Delta variant infections could have led to widespread transmission and substantial disease burden in mainland China, even with vaccination coverage as high as 89% across the eligible age groups. Extending the vaccination roll-out to include children aged 3–11 years (as it was the case since the end of October 2021) is estimated to dramatically decrease the burden of symptomatic infections and hospitalisations within this age group (39% and 68%, respectively, when considering a vaccination coverage of 87%), but would have a low impact on protecting infants. Our findings highlight the importance of including children among the target population and the need to strengthen vaccination efforts by increasing vaccine effectiveness.
