description: Magnetic fields influence the formation and evolution of stars and impact the observed stellar properties. Ap stars (magnetic A-type stars) are a prime example of this. Access to precise and accurate determinations of their stellar fundamental properties, such as masses and ages, is crucial to understand the origin and evolution of fossil magnetic fields. We propose using the radii and luminosities determined from interferometric measurements, in addition to seismic constraints when available, to infer fundamental properties of 14 Ap stars préviously characterised. We used a grid-based modelling approach, employing stellar models computed with the \textsc{cestam} stellar evolution code, and the parameter search performed with the \textsc{aims} optimisation method. The stellar model grid was built using a wide range of initial helium abundances and metallicities in order to avoid any bias originating from the initial chemical composition. The large frequency separations ($Δν$) of HR\,1217 (HD\,24712) and $α$~Cir (HD\,128898), two rapidly oscillating Ap stars of the sample, were used as seismic constraints. We inferred the fundamental properties of the 14 stars in the sample. The overall results are consistent within $1σ$ with previous studies, however, the stellar masses inferred in this study are higher. This trend likely originates from the broader range of chemical compositions considered in this work. We show that the use of $Δν$ in the modelling significantly improves our inferences, allowing us to set reasonable constraints on the initial metallicity which is, otherwise, unconstrained. This gives an indication of the efficiency of atomic diffusion in the atmospheres of roAp stars and opens the possibility of characterising the transport of chemical elements in their interiors.

Hydrogen sulfide removal from biogas with a fixed bed of rusted iron turnings
Creators: name: Canas, Carlos Gonzalo
Publisher: name: University of British Columbia
Year: 2010

description: Biogas produced at farm level has many applications, however the hydrogen sulfide must be eliminated from the biogas to prevent any possible damage to equipment, users and operators, and the environment. Among the various options available to the farmer to clean hydrogen sulfide from biogas a fixed-bed of rusted iron turnings seems appropriate. This study investigated the effectiveness of a fixed bed of rusted iron turnings in eliminating hydrogen sulfide. For that purpose, dynamic bench scale test were done to study the effects of flow rate (0.5 l/min, 0.75 l/min and 1.0 l/min) and hydrogen sulfide concentration (100 ppm and 200 ppm). The gas used was a mixture of saturated carbon dioxide and hydrogen sulfide. The iron turnings were made with a uniform thickness and width and allowed to oxidize under atmospheric conditions for 8 weeks. The resulting breakthrough curves were well described by sigmoidal curves. The breakpoint time was affected by flow rate and hydrogen sulfide concentration. At the higher flows and concentrations the breakpoint times were smaller. In contrast, the mass of hydrogen sulfide removed up to breakpoint time was independent of flow rate and hydrogen sulfide concentration (0.83 g). Nevertheless, the maximum removal capacity was independent of hydrogen sulfide concentration but dependent on flow rate. The rate data conformed well to a surface rate model, however the calculated pseudo-rate constants were different for the flow rates and hydrogen sulfide concentrations used in this study. Thus it was not possible to define a mechanism control for the rate of reaction. The fixed-bed was able to eliminate hydrogen sulfide from the gas mixture, however only 30 to 44% of the iron oxide reacted.

description: QCD at finite temperature and density is becoming increasingly important for various experimental programmes, ranging from heavy ion physics to astro-particle physics. The non-perturbative nature of non-abelian quantum field theories at finite temperature leaves lattice QCD as the only tool by which we may hope to come to reliable predictions from first principles. This requires careful extrapolations to the thermodynamic, chiral and continuum limits in order to eliminate systematic effects introduced by the discretization procedure. After an introduction to lattice QCD at finite temperature and density, its possibilities and current systematic limitations, a review of present numerical results is given. In particular, plasma properties such as the equation of state, screening masses, static quark free energies and spectral functions are discussed, as well as the critical temperature and the QCD phase structure at zero and finite density.

description: Chiral condensate and $η^\prime$ meson mass spectrum are studied under the influence of an external Abelian magnetic field. We work within the D3/D7 Karch--Katz model of flavoured AdS/CFT with supersymmetry broken by the Constable--Myers deformation of the metric. It is shown that this setting yields a quadratic dependence of condensate on field, rather than the non-analytic (linear in field) dependence, typical for chiral perturbation theory in the exact chiral limit. We argue that the analytic (quadratic) result must be put into correspondence with the leading-order in the $1/N_c$ decomposition for the condensate, whereas the existing chiral perturbation theory result, which is linear in field strength, is $1/N_c$ suppressed.

description: Nanoindentation-induced phase transformation in silicon has been studied. A series of nanoindentations were made with the sharp diamond Berkovich tip. During nanoindentations, maximum load ranged from 2000 $μ$N to 5000 $μ$N, with a 1000 $μ$N/sec loading rate. Slow unloading rate at 100$μ$N/sec was chosen to favor the formation of the crystalline end phases, high pressure phase (Si-III and Si-XII). Fast unloading rate at 1000$μ$N/sec was used to obtain amorphous phase. The phase transformation was examined by Raman spectroscopy and plan-view transmission electron microscopy (TEM). HPP have been identified even if no "pop-in" and "pop-out" observed in load-depth characteristics curves. HPP appeared in c-Si when the maximum load up to 3000 $μ$N. TEM images have been revealed that the optimization HPP transformation in c-Si at the nanoscale occurred when the maximum load applied at 5000 $μ$N.

In the specimen from 13.VIII, tergite 1 is yellow and tergites 2-4 are reddish brown. In the specimen from 27.IV, tergites 1-6 (tergite 1 blackish in anterior 0.4) are dark reddish brown (Fig. 8), and in both specimens the metasoma is yellowish posteriorly (Fig. 8). The specimen from 27.IV, mentioned as “ Labena sp. n.” by Hernández et al. (2000), also has the propodeum with the area superomedia widely open posteriorly (Fig. 6). This area is more or less defined in the other Mexican specimens, but is very variable in the Costa Rican material, in which sometimes the posterior carina is only very faintly present (G. Broad, pers. comm.). Both specimens are structurally similar to L. tarsata and have no other differences from typical specimens of this species in our material, excepting this one very variable character (area superomedia open posteriorly in female from 27.IV). Thus we consider these specimens to be a darker variation of L. tarsata.

Role of the MLL-AF4 chimeric protein in the molecular pathogenesis of t(4;11) acute lymphoblastic leukemia
Creators: name: Imperato, Maria Rosaria
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2012

description: Chromosomal rearrangements involving the Mixed Lineage Leukemia (MLL) gene are associated with very aggressive forms of acute lymphoblastic leukemia (ALL), often refractory to conventional therapies. In particular, patients carrying the translocation t(4;11)(q21;q23) have the worst prognosis among patients with other MLL-associated malignancies. Although it has been largely shown that the MLL-AF4 fusion protein has the capability to up-regulate genes involved in the self-renewal/differentiation balance of the hematopoietic stem cell, the mechanism induced by this oncoprotein is still poorly understood. Previous functional proteomic studies performed in our group identified the molecular partners of the native AF4 protein, the most common MLL translocation partner in infant ALL, and confirmed that this protein is deeply involved in a complex protein network, important for the regulation of the Pol II-dependent transcription. In this study, we cloned in an eukaryotic expression vector the complete cDNA encoding MLL-AF4 and transiently expressed the recombinant protein in Hek293 cells. In order to understand which molecules take part in the aberrant pathway induced by the MLL-AF4 oncoprotein, we aimed to identify some of its molecular interactors, starting from the proteins that are already known to interact with AF4. We showed that MLL-AF4 binds to CdK9 that by interacting with cyclin T1 forms the positive elongation factor (P-TEFb), which is involved in the activation of the Pol II elongation machinery. We also found that MLL-AF4 interacts with CRSP130 and CRSP33, two members of the so-called “Mediator Complex”, thus suggesting that MLL-AF4 is involved in the regulation of the Pol II-dependent transcription. Interestingly, we found that MLL-AF4 also interacts with the tyrosine-kinase receptor FGFR2, and with a protein belonging to the family of 14-3-3s (the isoform θ), involved in diverse intracellular pathways. Moreover, we observed down-regulation in the expression of HoxA9, one of the MLL target genes, in the cells co-expressing both recombinant MLL-AF4 and 14-3-3 θ, thus suggesting that this interaction could modulate transcriptional processes induced by MLL-AF4. Elucidating the role of fusion protein interactors such as FGFR2 and 14-3-3 θ is very important for identifying new molecular targets for the therapy of the MLL-AF4-dependent B-cell ALL.

description: We present a spectroscopic and imaging study of an abnormal active galactic nucleus (AGN), 2MASX J00423991+3017515. This AGN is newly identified in the hard X-rays by the Swift BAT All-Sky survey and found in an edge-on disk galaxy interacting with a nearby companion. Here, we analyze the first optical spectra obtained for this system (taken in 2011 and 2016), high-resolution imaging taken with the Hubble Space Telescope and Chandra X-ray Observatory, and 1" imaging with the Very Large Array. Two unique properties are revealed: the peaks of the broad Balmer emission lines (associated with gas orbiting very near the supermassive black hole) are blue shifted from the corresponding narrow line emission and host galaxy absorption by 1540 km/s, and the AGN is spatially displaced from the apparent center of its host galaxy by 3.8 kpc. We explore several scenarios to explain these features, along with other anomalies, and propose that 2MASX J00423991+3017515 may be an AGN with an unusually strong wind residing in a uniquely configured major merger, or that it is an AGN recoiling from either a gravitational "slingshot" in a three-body interaction or from a kick due to the asymmetric emission of gravitational waves following the coalescence of two progenitor supermassive black holes.

description: Wigner symmetry in Nuclear Physics provides a unique example of a non-perturbative long distance symmetry, a symmetry strongly broken at short distances. We analyse the consequences of such a concept within the framework of One Boson Exchange Potentials in NN scattering and keeping the leading Nc contributions. Phenomenologically successful relations between singlet 1S0 and triplet 3S1 scattering phase shifts are provided in the entire elastic region. We establish symmetry breaking relations among non-central phase shifts which are successfully fulfilled by even-L partial waves and strongly violated by odd-L partial waves, in full agreement with large Nc requirements.

description: We report the observations of the highly active FRb20201124A with the upgraded Giant Metrewave Radio Telescope at 550-750~MHz. These observations in the incoherent array mode simultaneously provided an arcsecond localization of bursts from \rss, the discovery of persistent radio emission associated with the host galaxy, and the detection of 48 bursts. Using the brightest burst in the sample ($F= 108~{\rm Jy~ms}$) we find a structure-maximizing dispersion measure of $410.8 \pm 0.5~{\rm pc~cm}^{-3}$. We find that our observations are complete down to a fluence level of $10~{\rm Jy~ms}$, above which the cumulative burst rate scales as a power-law $R(>\!F) = 10~{\rm hr}^{-1} \left(F/10\mathrm{~Jy~ms}\right)^γ$ with $γ= -1.2 \pm 0.2$. We find that the bursts are on average wider than those reported for other repeating FRBs. We find that the waiting time between bursts is well approximated by an exponential distribution with a mean of $\sim 2.9$ min during our observations. We searched for periodicities using both a standard Fourier domain method and the Fast Folding Algorithm, but found no significant candidates. We measure bulk spectro-temporal drift rates between $-0.75$ and $-20~{\rm MHz~ms}^{-1}$. Finally, we use the brightest burst to set an upper limit to the scattering time of 11.1~ms at 550~MHz. The localization of FRB20201124A adds strength to the proof-of-concept method described in our earlier work and serves as a potential model for future localizations and follow-up of repeating FRBs with the uGMRT.

Assessing the climate response to regional sea ice change across all Arctic regions

description: Climate models predict that sea ice cover will shrink--even disappear-- in most regions of the Arctic basin by the end of the century, triggering local and remote responses in the surface climate via atmospheric and oceanic circulation changes. In particular, it has been suggested that seasonal anomalies over Europe and North America in recent years could have been caused by record low Arctic sea ice cover. Despite an intense research effort toward quantifying its effect, the contribution of regional sea ice loss to climate change and its mechanisms of action remain controversial.  In this study, we prescribe sea ice loss in individual sectors of the Arctic within a climate model, and study its effect on climatic anomalies in the Northern Hemisphere. Using the EC-EARTH3.3 model in its atmospheric-only and fully coupled configuration, and following the PAMIP protocol, sea ice cover is set to either its present day state, or a hypothetical future distribution of reduced sea ice cover in the Arctic. This pan-Arctic sea ice loss experiment is then complemented by 8 regional sea ice loss experiments. Comparing those experiments, we assess the contribution of sea ice loss in each region of the Arctic to climate change over Europe, Siberia and North America. We find that sea ice loss in some sectors of the Arctic appear to matter much more for Northern Hemisphere climate change than others, even after normalizing for differences in surface cover. Furthermore, the climatic effect of regional sea ice loss is compared to that of a pan-Arctic sea ice loss, whose associated climate anomalies are found to be strikingly different from that expected from a simple linear response to regional sea ice loss. We propose a mechanism for this nonlinearity in the climate response to sea ice loss, which considers regional differences in the strength of the thermal inversion over the Arctic, as well as the proximity of various Arctic regions to features critical for stationary wave genesis (e.g. the Tibetan plateau, the Kuroshio and the Gulf Stream).

description: We study in detail the photometric redshift requirements needed for tomographic weak gravitational lensing in order to measure accurately the Dark Energy equation of state. In particular, we examine how ground-based photometry (u,g,r,i,z,y) can be complemented by space-based near-infrared (IR) photometry (J,H), e.g. on board the planned DUNE satellite. Using realistic photometric redshift simulations and an artificial neural network photo-z method we evaluate the Figure of Merit for the Dark Energy parameters $(w_0, w_a)$. We consider a DUNE-like broad optical filter supplemented with ground-based multi-band optical data from surveys like the Dark Energy Survey, Pan-STARRS and LSST. We show that the Dark Energy Figure of Merit would improved by a factor of 1.3 to 1.7 if IR filters are added on board DUNE. Furthermore we show that with IR data catastrophic photo-z outliers can be removed effectively. There is an interplay between the choice of filters, the magnitude limits and the removal of outliers. We draw attention to the dependence of the results on the galaxy formation scenarios encoded into the mock galaxies, e.g the galaxy reddening. For example, deep u band data could be as effective as the IR. We also find that about $10^5-10^6$ spectroscopic redshifts are needed for calibration of the full survey.

description: Sea ice loss results from anthropogenic global warming and can itself be a driver of climate change in the Arctic and at lower latitudes, with extreme events over Europe and North America having been attributed to sea ice minima in recent years. Yet the role that sea ice plays in ongoing climate change remains uncertain, partly due to a limited understanding of whether and how the exact geographical distribution of sea ice loss impacts climate. Here we analyse idealised AMIP-like simulations to compare the atmospheric response to various patterns of regional sea ice loss. We find that climatic anomalies can vary widely depending on where sea ice is reduced, with changes in the zonal-mean component of the tropospheric circulation being seemingly inconsistent among experiments. We attribute this disparate climatic response to an atmospheric feedback mechanism, which can either warm or cool the Arctic troposphere depending on the relative magnitude of the changes in poleward eddy heat flux and latent heat release over the Arctic in response to a specific sea ice loss pattern. We discuss the implications of our results for interpreting the apparent discrepancies in the climate response to Arctic sea ice variability among studies. Our study highlights the need to better constrain the spatial pattern of future sea ice when assessing its impacts on the climate in the Arctic. By explaining the link between sea ice pattern and Arctic climate variability, our study will inform the design and analysis of future climate simulations and multi-model comparison protocols.

description: We present the Submillimeter Array observation of the CO J=2-1 transition towards the northern galaxy, ARP 302N, of the early merging system, ARP 302. Our high angular resolution observation reveals the extended spatial distribution of the molecular gas in ARP 302N. We find that the molecular gas has a very asymmetric distribution with two strong concentrations on either side of the center together with a weaker one offset by about 8 kpc to the north. The molecular gas distribution is also found to be consistent with that from the hot dust as traced by the 24 micro continuum emission observed by the Spitzer. The line ratio of CO J=2-1/1-0 is found to vary strongly from about 0.7 near the galaxy center to 0.4 in the outer part of the galaxy. Excitation analysis suggests that the gas density is low, less than 10$^3$ cm$^{-3}$, over the entire galaxy. By fitting the SED of ARP 302N in the far infrared we obtain a dust temperature of $T\rm_d$=26-36 K and a dust mass of M$\rm _{dust}$=2.0--3.6$\times10^8$ M$\rm_\odot$. The spectral index of the radio continuum is around 0.9. The spatial distribution and spectral index of the radio continuum emission suggests that most of the radio continuum emission is synchrotron emission from the star forming regions at the nucleus and ARP302N-cm. The good spatial correspondance between the 3.6 cm radio continuum emission, the Spitzer 8 & 24 $μ$m data and the high resolution CO J=2-1 observation from the SMA shows that there is the asymmetrical star forming activities in ARP 302N.

description: High Tc Josephson nanoJunctions (HTc JnJ) made by ion irradiation have remarkable properties for technological applications. However, the spread in their electrical characteristics increases with the ion dose. We present a simple model to explain the JnJ inhomogeneities, which accounts quantitatively for experimental data. The spread in the slit's width of the irradiation mask is the limiting factor.Monte Carlo simulations have been performed using different irradiation conditions to study their influence on the spread of the JnJ charcateristics. A "universal" behavior has been evidenced, which allows to propose new strategies to optimize JnJ reproducibility.

description: The material and electrical properties of the CNT single vias and array vias grown by microwave plasma-enhanced chemical vapor deposition were investigated. The diameters of multiwall carbon nanotubes (MWNTs) grown on the bottom electrode of Ta decrease with increasing pretreatment power and substrate temperature while the effects of the growth power and methane flow ratio are insignificant The decrease of CNT diameters leads to the decrease of the CNT via diode devices. The increase of growth power enhances the CNT graphitization degree and thue the conductivity of CNT via diode devices. In the same via region, the MWNT diode resistances of the array vias are lower than those of the single vias. The MWNT diode resistances on the bottom electrode of titanium are lower than those on the bottom electrode of tantalum. It may be attributed to the smaller tube diameters on the bottom electrode of Ti and the work function difference between Ta and Ti films with respect to the work function of CNTs.

description: We obtain an exact spherically symmetric and magnetically charged black hole solution in 4D Einstein-Gauss-Bonnet gravity coupled with nonlinear electrodynamics with the Lagrangian ${\cal L}_{NED} = -{\cal F}/(1+\sqrt{2\midβ{\cal F}\mid})$ (${\cal F}$ is the field strength invariant). The thermodynamics of the black hole is studied within our model. We calculate the Hawking temperature and the heat capacity of the black hole. The phase transitions occur in the point where the Hawking temperature possesses an extremum and the heat capacity diverges. It was shown that black holes are thermodynamically stable in some range of event horizon radii when the heat capacity and Hawking temperature are positive. The logarithmic correction to the Bekenstein - Hawking BH entropy is obtained which mimics a quantum correction. The dependence of the BH shadow radius on the model parameters is studied. We also investigate the particle emission rate of the BH. The stability of the BH is studied by analysing the quasinormal modes.

Branch production and fragmentation in the conidia of Pseudozyma prolifica
Creators: name: Wiebe, Marilyn Gail
Publisher: name: University of British Columbia
Year: 2010

description: The hyphomycete Pseudozyma prolifica Bandoni was grown in batch and continuous liquid cultures to determine the influence of growth rate and nutrition on conidium development. In batch culture, a period of elongation and branch formation, followed by fragmentation, was typically observed. The stage of branch formation was almost completely eliminated when the amino acids phenylalanine, glutamic acid, or asparagine were substituted for nitrate. Substituting citric acid for glucose had a similar effect. Branch formation was enhanced in sucrose + nitrate medium. In batch cultures, branched growth occurred at the start of the exponential growth phase. In continuous culture, the extent of branching was dependent on the specific growth rate. Maximal branching was observed at growth rates near the maximum. Growth by elongation and "bud" formation was predominant at low growth rates, as at the end of the log phase in batch cultures. The conidia were also examined using fluorescence and electron microscopy. Staining with wheat germ agglutinin conjugated to Fluorescein Isothiocyanate indicated that some intercalary growth occurs.

description: We present a new, detailed analysis of late-time mid-infrared (IR) observations of the Type II-P supernova (SN) 2003gd. At about 16 months after the explosion, the mid-IR flux is consistent with emission from 4 x 10^(-5) M(solar) of newly condensed dust in the ejecta. At 22 months emission from point-like sources close to the SN position was detected at 8 microns and 24 microns. By 42 months the 24 micron flux had faded. Considerations of luminosity and source size rule out the ejecta of SN 2003gd as the main origin of the emission at 22 months. A possible alternative explanation for the emission at this later epoch is an IR echo from pre-existing circumstellar or interstellar dust. We conclude that, contrary to the claim of Sugerman et al. (2006, Science, 313, 196), the mid-IR emission from SN 2003gd does not support the presence of 0.02 M(solar) of newly formed dust in the ejecta. There is, as yet, no direct evidence that core-collapse supernovae are major dust factories.

description: We investigate the enhancement of the curvature perturbations in a single-field slow-roll inflation with a spectator scalar field kinetically coupled to the inflaton. The coupling term with a periodic function of inflaton triggers the exponential growth of the spectator field perturbations, which indirectly amplifies the curvature perturbations to produce a sizable abundance of primordial black holes (PBHs). This scenario is found to be insensitive to the inflationary background. We study two distinct populations of the stochastic gravitational wave background (SGWB) produced in this scenario, i.e., induced by the scalar perturbations during the inflationary era and the radiation-dominated era, respectively. With the appropriate choices of parameter space, we consider two PBH mass windows of great interest. One is PBHs of masses $\mathcal{O}(10^{-12})M_\odot$ that can be a vital component of dark matter, and the predicted total energy spectrum of SGWB shows a unique profile and is detectable by LISA and Taiji. The other is PBHs of masses $\mathcal{O}(10)M_\odot$ which can provide consistent explanation for the LIGO-Virgo events. More interestingly, the predicted gravitational wave signal from the radiation-dominated era may account for the NANOGrav results.

description: While it is recognized that farming alternatively is inherently knowledge intensive, in the United States, farmer knowledge has been widely overlooked and under-documented within the scientific literature. Farmer knowledge of soil in particular is understudied in the US, especially given that healthy soils have been identified as the basis for resilient agriculture. Applying an exploratory, case study approach, we interviewed 13 organic farmers based in Yolo County, California to understand how organic farmers in this region acquire knowledge about their soils, to document what organic farmers in this region know about their soils, and to share key management practices organic farmers use to build soil health in the region. We found the organic farmers in this study acquire knowledge about their farming systems primarily through direct observation, personal experience, experimentation, and inherited wisdom. To evaluate soil health, farmers in this study cited using a range of indicators, including soil structure, crop health, growth habits of weeds, and soil biology. We found that these organic farmers possess extensive place-based knowledge of their local farming systems, and that this knowledge base represents an important source for innovation and adaptive management in scientific and policy-making contexts.
Extended Supersymmetric Moduli Space and a SUSY/Non-SUSY Duality

description: We study N=1 supersymmetric U(N) gauge theories coupled to an adjoint chiral field with superpotential. We consider the full supersymmetric moduli space of these theories obtained by adding all allowed chiral operators. These include higher-dimensional operators that introduce a field-dependence for the gauge coupling. We show how Feynman diagram/matrix model/string theoretic techniques can all be used to compute the IR glueball superpotential. Moreover, in the limit of turning off the superpotential, this leads to a deformation of N=2 Seiberg-Witten theory. In the case where the superpotential drives the squared gauge coupling to a negative value, we find that supersymmetry is spontaneously broken, which can be viewed as a novel mechanism for breaking supersymmetry. We propose a new duality between a class of N=1 supersymmetric U(N) gauge theories with field-dependent gauge couplings and a class of U(N) gauge theories where supersymmetry is softly broken by nonzero expectation values for auxiliary components of spurion superfields.

description: We present the first results from the Quasar Feedback Survey, a sample of 42 z<0.2, [O III] luminous AGN (L[O III]>10^42.1 ergs/s) with moderate radio luminosities (i.e. L(1.4GHz)>10^23.4 W/Hz; median L(1.4GHz)=5.9x10^23 W/Hz). Using high spatial resolution (~0.3-1 arcsec), 1.5-6 GHz radio images from the Very Large Array, we find that 67 percent of the sample have spatially extended radio features, on ~1-60 kpc scales. The radio sizes and morphologies suggest that these may be lower radio luminosity versions of compact, radio-loud AGN. By combining the radio-to-infrared excess parameter, spectral index, radio morphology and brightness temperature, we find radio emission in at least 57 percent of the sample that is associated with AGN-related processes (e.g. jets, quasar-driven winds or coronal emission). This is despite only 9.5-21 percent being classified as radio-loud using traditional criteria. The origin of the radio emission in the remainder of the sample is unclear. We find that both the established anti-correlation between radio size and the width of the [O III] line, and the known trend for the most [O III] luminous AGN to be associated with spatially-extended radio emission, also hold for our sample of moderate radio luminosity quasars. These observations add to the growing evidence of a connection between the radio emission and ionised gas in quasar host galaxies. This work lays the foundation for deeper investigations into the drivers and impact of feedback in this unique sample.

description: Climate models predict that sea ice cover will shrink--even disappear-- in most regions of the Arctic basin by the end of the century, inducing local and remote responses in the surface climate via dynamical changes in the atmospheric circulation. The atmospheric-only experiment designed and performed within PAMIP can help us elucidate the dynamical mechanisms, as well as assess the importance of sea ice loss in individual sectors of the Arctic in driving Northern Hemisphere climate change.  Using the atmosphere-only EC-EARTH3.3 model and using the same protocol as for the pan-Arctic and regional Barents/Kara and Okhotsk future sea-ice experiments, we ran 5 complementary regional experiments that include other regions of the Arctic: Central Arctic, Hudson-Labrador-Baffin, Irminger-GIN, Bering-Chukchi, and Beaufort-East-Siberian-Laptev sectors. First. we compare the spatial pattern of climate anomalies in those simulations, and we discuss the contribution of sea ice loss in each region to climate change over Europe, Siberia and North America. One noticeable result that will be discussed is the strikingly different nature of the climate response to pan-Arctic sea ice loss when compared to any of the regional sea ice loss experiments; we conclude our presentation by discussing potential causes for this difference, and what it may imply when devising experiments with prescribed regional sea ice change in future projects.
