description: Effectively separating Zr(IV) from strong acidic and radioactive solutions is crucial for spent fuel reprocessing plants, but it remains a challenging task. This study investigated the adsorption of Zr(IV) in HNO3 solutions using zeolites as adsorbents. The zeolites were characterized by X-ray diffraction (XRD)，scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The effects of adsorption time, HNO3 concentration, the initial concentration of Zr(IV), zeolites dosage, and temperature on the Zr(IV) adsorption behaviors were investigated. The results demonstrated that HY zeolite had a higher adsorption capacity for Zr(IV) than H-SSZ-13 zeolite. The adsorption capacity of HY zeolite was influenced by its Si/Al ratio, which determined the density of adsorption sites. The optimal HY zeolite (HY-25) exhibited a maximum adsorption capacity of 30.438 mg/g in 3 M HNO3 solution. Furthermore, the adsorption isotherms and kinetics of Zr(IV) adsorption were investigated. The adsorption of Zr(IV) on zeolites was endothermic and spontaneous, in accordance with the Freundlich’s isotherm model and pseudo-second-order kinetic model. In a simulated strong acidic solution of Zr(IV) and 10 co-existing cations (Ag+, Ba2+, Cs+, Ce3+, Eu3+, Fe3+, La3+, Nd3+, Sm3+, Sr2+), HY-25 exhibited good selective adsorption of Zr(IV), indicating its potential application in the treatment of high-level radioactive liquid waste.

description: Correlations may affect propagation processes on complex networks. To analyze their effect, it is useful to build ensembles of networks constrained to have a given value of a structural measure, such as the degree-degree correlation $r$, being random in other aspects and preserving the degree distribution. This can be done through Monte Carlo optimization procedures. Meanwhile, when tuning $r$, other network properties may concomitantly change. Then, in this work we analyze, for the $r$-ensembles, the impact of $r$ on properties such as transitivity, branching and characteristic lengths, that are relevant when investigating spreading phenomena on these networks. The present analysis is performed for networks with degree distributions of two main types: either localized around a typical degree (with exponentially bounded asymptotic decay) or broadly distributed (with power-law decay). Correlation bounds and size effects are also investigated.

description: ICOS provides long term, high quality observations that follow (and cooperatively set) the global standards for the best possible quality data on the atmospheric composition for greenhouse gases (GHG), greenhouse gas exchange fluxes measured by eddy covariance and CO2 partial pressure at water surfaces. The ICOS observational data feeds into a wide area of science that covers for example plant physiology, agriculture, biology, ecology, energy & fuels, forestry, hydrology, (micro)meteorology, environmental, oceanography, geochemistry, physical geography, remote sensing, earth-, climate-, soil- science and combinations of these in multi-disciplinary projects.

As ICOS is committed to provide all data and methods in an open and transparent way as free data, a dedicated system is needed to secure the long term archiving and availability of the data together with the descriptive metadata that belongs to the data and is needed to find, identify, understand and properly use the data, also in the far future, following the FAIR data principles. An added requirement is that the full data lifecycle should be completely reproducible to enable full trust in the observations and the derived data products.

In this report we we define and describe the implemention of a comprehensive unified metadata flow from Thematic Centres to the Carbon Portal. The design criteria of this system were to integrate as much as possible the operational (legacy) database systems at the TCs with the data portal, thereby preserving the investments in the robust and proven QA/QC and database systems at the TCs and combining these with the benefits of a linked open data system with connected data licence check, usage tracking and dynamic machine operable data and metadata based on a versioned RDF triple store.

Also we developed a connected DOI minting system, implemented the generation of data collections and a linked system for versioning of the data, all connected to the ontology driven single point of ingestion, optimised for machine to machine communication. This has been used incrementally in full operational mode over the last years and is now in place and used by all ICOS domains for all data streams, from raw data through near-real-time to final quality controlled data, and by the external users that provide elaborated products.

The licence check and data usage tracking has been implemented in a completely unobtrusive way and is flexible enough to be started to interoperate with major data portals like those of FLUXNET, NEON, SOCAT and WMO WDCGG. The use of DOIs increases the exposure of the ICOS data to global and European data portals like the future EOSC portal and current OpenAIRE portal and Google Dataset Search. The ICOS data is already finding it way to many users and the growing length of the ICOS timeseries in all domains and the interoperation with the global portals this data use of ICOS data can now grow further optimally.

Search for anomaly-mediated supersymmetry breaking with the ATLAS detector based on a disappearing-track signature in pp collisions at sqrt(s) = 7 TeV

description: In models of anomaly-mediated supersymmetry breaking (AMSB), the lightest chargino is predicted to have a lifetime long enough to be detected in collider experiments. This letter explores AMSB scenarios in pp collisions at sqrt(s) = 7 TeV by attempting to identify decaying charginos which result in tracks that appear to have few associated hits in the outer region of the tracking system. The search was based on data corresponding to an integrated luminosity of 1.02 fb^-1 collected with the ATLAS detector in 2011. The pT spectrum of candidate tracks is found to be consistent with the expectation from Standard Model background processes and constraints on the lifetime and the production cross section were obtained. In the minimal AMSB framework with m_3/2 < 32 TeV, m_0 < 1.5 TeV, tan(beta) = 5 and mu > 0, a chargino having mass below 92 GeV and a lifetime between 0.5 ns and 2 ns is excluded at 95% confidence level.

description: We present a simple isomorphism between the algebra of one real chiral Fermi field and the algebra of n real chiral Fermi fields. This isomorphism preserves the vacuum state. This is possible by a "change of localization", and gives rise to new multilocal symmetries generated by the corresponding multilocal current and stress-energy tensor. The result gives a common underlying explanation of several remarkable recent results on the representation of the free Bose field in terms of free Fermi fields, and on the modular theory of the free Fermi algebra in disjoint intervals.

description: We devise a way to calculate the dimensions of symmetry sectors appearing in the Particle Entanglement Spectrum (PES) and Real Space Entanglement Spectrum (RSES) of multi-particle systems from their real space wave functions. We first note that these ranks in the entanglement spectra equal the dimensions of spaces of wave functions with a number of particles fixed. This also yields equality of the multiplicities in the PES and the RSES. Our technique allows numerical calculations for much larger systems than were previously feasible. For somewhat smaller systems, we can find approximate entanglement energies as well as multiplicities. We illustrate the method with results on the RSES and PES multiplicities for integer quantum Hall states, Laughlin and Jain composite fermion states and for the Moore-Read state at filling $ν=5/2$, for system sizes up to 70 particles.

Coherent perfect absorbers for transient, periodic or chaotic optical fields: time-reversed lasers beyond threshold

description: Recent works [Y.D. Chong {\it et al.}, Phys. Rev. Lett. {\bf 105}, 053901 (2010); W. Wan {\it et al.}, Science {\bf 331}, 889 (2011)] have shown that the time-reversed process of lasing at threshold realizes a coherent perfect absorber (CPA). In a CPA, a lossy medium in an optical cavity with a specific degree of dissipation, equal in modulus to the gain of the lasing medium, can perfectly absorb coherent optical waves at discrete frequencies that are the time-reversed counterpart of the lasing modes. Here the concepts of time-reversal of lasing and CPA are extended for optical radiation emitted by a laser operated in an arbitrary (and generally highly-nonlinear) regime, i.e. for transient, chaotic or periodic coherent optical fields. We prove that any electromagnetic signal $E(t)$ generated by a laser system \textbf{S} operated in an arbitrary regime can be perfectly absorbed by a CPA device $\bf{S'}$ which is simply realized by placing inside \textbf{S} a broadband linear absorber (attenuator) of appropriate transmittance. As examples, we discuss CPA devices that perfectly absorb a chaotic laser signal and a frequency-modulated optical wave.

description: Cosmological surveys aim to use the evolution of the abundance of galaxy clusters to accurately constrain the cosmological model. In the context of LCDM, we show that it is possible to achieve the required percent level accuracy in the halo mass function with gravity-only cosmological simulations, and we provide simulation start and run parameter guidelines for doing so. Some previous works have had sufficient statistical precision, but lacked robust verification of absolute accuracy. Convergence tests of the mass function with, for example, simulation start redshift can exhibit false convergence of the mass function due to counteracting errors, potentially misleading one to infer overly optimistic estimations of simulation accuracy. Percent level accuracy is possible if initial condition particle mapping uses second order Lagrangian Perturbation Theory, and if the start epoch is between 10 and 50 expansion factors before the epoch of halo formation of interest. The mass function for halos with fewer than ~1000 particles is highly sensitive to simulation parameters and start redshift, implying a practical minimum mass resolution limit due to mass discreteness. The narrow range in converged start redshift suggests that it is not presently possible for a single simulation to capture accurately the cluster mass function while also starting early enough to model accurately the numbers of reionisation era galaxies, whose baryon feedback processes may affect later cluster properties. Ultimately, to fully exploit current and future cosmological surveys will require accurate modeling of baryon physics and observable properties, a formidable challenge for which accurate gravity-only simulations are just an initial step.

description: Motivated by observations that suggest the presence of extremely massive clusters at uncomfortably high redshifts for the standard cosmological model to explain, we develop a theoretical framework for the study of the most massive haloes, e.g. the most massive cluster found in a given volume, based on Extreme Value Statistics (EVS). We proceed from the exact distribution of the extreme values drawn from a known underlying distribution, rather than relying on asymptotic theory (which is independent of the underlying form), arguing that the former is much more likely to furnish robust statistical results. We illustrate this argument with a discussion of the use of extreme value statistics as a probe of primordial non-Gaussianity.

description: (Abridged) We present here a detailed analysis of the star formation history (SFH) of FW4871, a massive galaxy at z=1.893+-0.002. We compare rest-frame optical and NUV slitless grism spectra from the Hubble Space Telescope with a large set of composite stellar populations to constrain the underlying star formation history. Even though the morphology features prominent tidal tails, indicative of a recent merger, there is no sign of on-going star formation within an aperture encircling one effective radius, which corresponds to a physical extent of 2.6 kpc. A model assuming truncation of an otherwise constant SFH gives a formation epoch zF~10, with a truncation after 2.7 Gyr, giving a mass-weighted age of 1.5 Gyr and a stellar mass of 0.8-3E11Msun, implying star formation rates of 30-110 Msun/yr. A more complex model including a recent burst of star formation places the age of the youngest component at 145 Myr, with a mass contribution lower than 20%, and a maximum amount of dust reddening of E(B-V)<0.4 mag (95% confidence levels). This low level of dust reddening is consistent with the low emission observed at 24 micron, corresponding to rest-frame 8 micron, where PAH emission should contribute significantly if a strong formation episode were present. The colour profile of FW4871 does not suggest a significant radial trend in the properties of the stellar populations out to 3Re. We suggest that the recent merger that formed FW4871 is responsible for the quenching of its star formation.

Regional heterogeneity of the vascular dysfunction in db/db mice : role of reactive oxygen species
Creators: name: Sallam, Nada A. Elmoneim
Publisher: name: University of British Columbia
Year: 2012

description: Background: The high mortality and morbidity rates associated with diabetes are mainly attributed to its cardiovascular complications. It remains questionable whether diabetes has a general deleterious effect on the vasculature, or if different arteries exhibit differential vulnerability to the diabetic milieu. This thesis compared the functional adaptation of three arteries: the aorta, carotid and femoral arteries, to the diabetic milieu present in db/db mice, and elucidated the mechanisms underlying the arteries' differential adaptation. Additionally, the functional and molecular alterations in the aorta and femoral artery in response to moderate-intensity exercise training were compared. Methods: Vasodilatory and contractile responses were examined in isolated aortae, carotid and femoral arteries from db/db and control mice to assess the endothelium and vascular smooth muscles' functions. Additionally, the protein expressions of endothelial nitric oxide synthase (eNOS), Akt, cyclooxygenase and superoxide dismutase (SOD) isoforms were examined. In parallel, plasma markers of glycemia, oxidative stress, inflammation, and dyslipidemia were measured. Thereafter, a correlation analysis was performed to estimate the strength of association between plasma variables and vascular responses. Results: The aortae of db/db mice exhibited a progressive impairment in endothelial and vascular smooth muscle functions. The carotid artery was the most resilient and maintained unaltered functional responses in db/db mice, likely because the carotid artery, in contrast to the aorta, relaxes in response to superoxide anion or peroxynitrite. The femoral arteries of db/db mice showed reduced endothelium-dependent hyperpolarizing factor-mediated vasodilatation and attenuated contractile responses, probably due to the lack of expression of extracellular SOD in the femoral artery. The benefits of exercise training were confined to nitric oxide-mediated vasodilatation in the aortae and femoral arteries of db/db mice, and were associated with increased eNOS/Akt and SOD expressions and reduced cardiovascular risk factors. Conclusions: Substantial heterogeneity exists between the aorta, carotid and femoral arteries both at functional (signalling pathways) and molecular levels (protein expression) under physiological and diabetic conditions. Understanding regional differences in vasomotor control, coupled with advanced drug delivery systems will open new venues for developing therapies that target specific vascular beds with minimal systemic side effects.

Molecular profiling of the peripheral blood response to allergen inhalation challenge in asthmatics
Creators: name: Kam, Sarah Hui Ying
Publisher: name: University of British Columbia
Year: 2012

description: Allergen inhalation challenge (AIC) triggers biphasic responses in allergic asthmatic individuals. Airway narrowing represents the early phase response, which typically occurs within 30 minutes of allergen inhalation. In 50-60% of allergic asthmatic adults, the early response is followed by the late phase response, usually starting around 3 hours after AIC, and characterized by cellular inflammation of the airway, increased lung tissue permeability, and mucus secretion. The pathways leading to the late response are not completely understood. The purpose of this thesis is to investigate the mechanisms behind the allergic asthmatic response profiles using peripheral blood samples obtained from asthmatics prior to and 2 hours following AIC. Subjects exhibited either an isolated early response of ≥20% fall in FEV₁ (isolated early responder – ER), or an early response followed by a late phase response of ≥15% fall in FEV₁ (dual responder – DR). Genome-wide transcriptional profiling using microarrays indicated significant perturbations in the Nrf2 (NF-E2-related factor 2)-mediated oxidative stress response pathway following allergen inhalation. Notably, the ABCC1 (ATP-binding cassette, sub-family C (CFTR/MRP), member 1) gene within the pathway showed a decreased expression post-challenge, as validated through RT-qPCR. Furthermore, a significant decrease in the level of plasma chemokine (C-C motif) ligand 2 (CCL2) was evident, which was replicated using immunoassays in additional cohorts of allergic rhinitis and individuals with occupational asthma. However, this may be attributable to inherent fluctuations, based on similar results from control subjects. The comparison of transcriptomic response profiles between ERs and DRs undergoing cat allergen inhalation challenge revealed linoleic acid metabolism as the most significant pathway. Separation of whole-blood gene expression profiles into cell-specific signals using the csSAM algorithm suggested that key transcriptomic differences lie in eosinophils and lymphocytes when comparing between ERs and DRs at the post-challenge time point. These findings are in support of the current model of asthma pathophysiology and provide valuable insights into molecular changes occurring as early as 2 hours after allergen inhalation. Further study into the underlying mechanisms leading to the different response patterns may expose new therapeutic targets effective in minimizing the late response, which is associated with chronic asthma.

description: Sediment transport is studied as a function of the grain to fluid density ratio using two phase numerical sim- ulations based on a discrete element method (DEM) for particles coupled to a continuum Reynolds averaged description of hydrodynamics. At a density ratio close to unity (typically under water), vertical velocities are so small that sediment transport occurs in a thin layer at the surface of the static bed, and is called bed load. Steady, or 'saturated' transport is reached when the fluid borne shear stress at the interface between the mobile grains and the static grains is reduced to its threshold value. The number of grains transported per unit surface is therefore limited by the flux of horizontal momentum towards the surface. However, the fluid velocity in the transport layer remains almost undisturbed so that the mean grain velocity scales with the shear velocity u\ast. At large density ratio (typically in air), the vertical velocities are large enough to make the transport layer wide and dilute. Sediment transport is then called saltation. In this case, particles are able to eject others when they collide with the granular bed, a process called splash. The number of grains transported per unit surface is selected by the balance between erosion and deposition and saturation is reached when one grain is statistically replaced by exactly one grain after a collision, which has the consequence that the mean grain velocity remains independent of u\ast. The influence of the density ratio is systematically studied to reveal the transition between these two transport regimes. Based on the mechanisms identified in the steady case, we discuss the transient of saturation of sediment transport and in particular the saturation time and length. Finally, we investigate the exchange of particles between the mobile and static phases and we determine the exchange time of particles.

description: The present work describes the synthesis of molnupiravir by employing commercially available inexpensive materials in two steps with an overall yield of 85.7%. The synthetic methodology starts with an eco-friendly starting material, that is, cytidine and establishes an alternative way to avoid costly enzyme mediated reactions. This synthetic strategy involves a selective acylation of cytidine as the first key step followed by the second step, that is, hydroxamination reaction. The major advantage of this protocol is that it is completely free of protection and deprotection reactions. Chemoselective acylation of cytidine’s primary alcohol was achieved using isobutyryl chloride, Et3N, and DMF solvent (89.3% yield). The aqueous phase transformation was achieved for the hydroxamination reaction with a 96% yield.

We obtain that the effective 4D masses of the neutrinos can only take three possible values, which are related to the (static) foliation of the fifth and noncompact extra dimension.

We reconstruct the potential and the dynamics for the Chaplygin scalar field model according to the evolutionary behavior of the ghost dark energy which can describe the phantomic accelerated expansion of the universe.

description: The central function of telomerase is maintaining the telomere length. However, several extra-telomeric roles have been identified for this protein complex. In this study, we evaluated the effect of the silencing of the catalytic subunit of telomerase (TERT) on the expression of candidate microRNAs, cell activation markers and glial-related genes in a glioblastoma cell line (T98G). The silencing was performed by a siRNA and the qPCR method was used to analyze the expression of TERT and downstream genes. Flow cytometry was used to quantify the TERT protein, and bioinformatics analysis was carried out to analyze the functions of microRNA target genes. Here, it was observed that after a 50% reduction of the TERT gene, the expression of ARG1 (Arginase 1) was upregulated, whereas NES (Nestin), GLUL (Glutamate-Ammonia Ligase), VIM (Vimentin) and the hsa-miR-29b-3p microRNA were downregulated (P-value <0.05). A bioinformatic analysis showed that target genes of hsa-miR-29b are associated with focal adhesion, the PI3K-Akt signaling pathway, among others. These results are important because they contribute to the knowledge of extratelomeric functions by providing relevant evidence about novel genes modulated by TERT.

description: We introduce a notion of a Fox pairing in a group algebra and use Fox pairings to define automorphisms of the Malcev completions of groups. These automorphisms generalize to the algebraic setting the action of the Dehn twists in the group algebras of the fundamental groups of surfaces. This work is inspired by the Kawazumi-Kuno generalization of the Dehn twists to non-simple closed curves on surfaces.

description: Let $G$ be a residually finite group and let $A$ be a finite set. We prove that if $X \subset A^G$ is a strongly irreducible subshift of finite type containing a periodic configuration then periodic configurations are dense in $X$. The density of periodic configurations implies in particular that every injective endomorphism of $X$ is surjective and that the group of automorphisms of $X$ is residually finite. We also introduce a class of subshifts $X \subset A^\Z$, including all strongly irreducible subshifts and all irreducible sofic subshifts, in which periodic configurations are dense.
Spatio-temporal Bounded Noises, and transitions induced by them in solutions of real Ginzburg-Landau model

description: In this work, we introduce two spatio-temporal colored bounded noises, based on the zero-dimensional Cai-Lin and Tsallis-Borland noises. We then study and characterize the dependence of the defined bounded noises on both a temporal correlation parameter $τ$ and on a spatial coupling parameter $λ$. The boundedness of these noises has some consequences on their equilibrium distributions. Indeed in some cases varying $λ$ may induce a transition of the distribution of the noise from bimodality to unimodality. With the aim to study the role played by bounded noises on nonlinear dynamical systems, we investigate the behavior of the real Ginzburg-Landau time-varying model additively perturbed by such noises. The observed phase transitions phenomenology is quite different from the one observed when the perturbations are unbounded. In particular, we observed an inverse "order-to-disorder" transition, and a re-entrant transition, with dependence on the specific type of bounded noise.

Quantum theory from the geometry of evolving probabilities

description: We consider the space of probabilities {P(x)}, where the x are coordinates of a configuration space. Under the action of the translation group there is a natural metric over the space of parameters of the group given by the Fisher-Rao metric. This metric induces a metric over the space of probabilities. Our next step is to set the probabilities in motion. To do this, we introduce a canonically conjugate field S and a symplectic structure; this gives us Hamiltonian equations of motion. We show that it is possible to extend the metric structure to the full space of the {P,S} and this leads in a natural way to a Kaehler structure; i.e., a geometry that includes compatible symplectic, metric and complex structures. The simplest geometry that describes these spaces of evolving probabilities has remarkable properties: the natural, canonical variables are precisely the wave functions of quantum mechanics; the Hamiltonian for the quantum free particle can be derived from a representation of the Galilean group using purely geometrical arguments; and it is straightforward to associate with this geometry a Hilbert space which turns out to be the Hilbert space of quantum mechanics. We are led in this way to a reconstruction of quantum theory based solely on the geometry of probabilities in motion.

description: In this article we present two new algorithms to compute the Groebner basis of an ideal that is invariant under certain permutations of the ring variables and which are both implemented in SINGULAR (cf. [DGPS12]). The first and major algorithm is most performant over finite fields whereas the second algorithm is a probabilistic modification of the modular computation of Groebner bases based on the articles by Arnold (cf. [A03]), Idrees, Pfister, Steidel (cf. [IPS11]) and Noro, Yokoyama (cf. [NY12], [Y12]). In fact, the first algorithm that mainly uses the given symmetry, improves the necessary modular calculations in positive characteristic in the second algorithm. Particularly, we could, for the first time even though probabilistic, compute the Groebner basis of the famous ideal of cyclic 9-roots (cf. [BF91]) over the rationals with SINGULAR.

description: Ethyne is often an unwanted impurity in ethene streams used in plastics industry. Supported Pd catalysts offer high ethyne conversion, but poor ethene selectivity due to over-hydrogenation which leads to the formation of carbonaceous deposits. In this paper, acrylamide was grafted by free radical polymerization onto bagasse pith hemicellulose (to form HEMI-g-AAMs), which was then used as a porous bio-based carrier of Pd nanoparticles. The obtained Pd/HEMI-g-AAMs catalyst showed an ethyne conversion and ethene selectivity of 100% and 94.70%, respectively, at 100 °C and a space velocity of 70,000 h−1. The nitrogen-rich bio-based support regulated the physicochemical properties and catalytic activity of the supported Pd nanoparticles. Results guide the development of new and improved Pd-based catalysts for the partial catalytic hydrogenation of ethyne to ethene.
The impact of a new median statistics $H_0$ prior on the evidence for dark radiation

description: Recent analyses that include cosmic microwave background (CMB) anisotropy measurements from the Atacama Cosmology Telescope and the South Pole Telescope have hinted at the presence of a dark radiation component at more than two standard deviations. However, this result depends sensitively on the assumption of an HST prior on the Hubble constant, where $H_0=73.8\pm2.4$ km/s/Mpc at 68% c.l.. From a median statistics (MS) analysis of 537 non-CMB $H_0$ measurements from Huchra's compilation we derive $H_0=68 \pm2.8$ km/s/Mpc at 68% c.l., in good agreement with the results of a recent analysis of the full Huchra list of $H_0$ measurements. This result is also fully consistent with the value of $H_0=69.7\pm2.5$ km/s/Mpc at 68% c.l. obtained from CMB measurements under assumption of the standard $Λ$CDM model. We show that with the MS $H_0$ prior the evidence for dark radiation is weakened to $\sim 1.2$ standard deviations. Parametrizing the dark radiation component through the effective number of relativistic degrees of freedom $N_{eff}$, we find $N_{eff}=3.98\pm0.37$ at 68% c.l. with the HST prior and $N_{eff}=3.52\pm0.39$ at 68% c.l. with the MS prior. We also discuss the implications for current limits on neutrino masses and on primordial Helium abundances.
