description: We present an ALMA study of the ~180 brightest sources in the SCUBA-2 map of the COSMOS field from the S2COSMOS survey, as a pilot study for AS2COSMOS - a full survey of the ~1,000 sources in this field. In this pilot we have obtained 870-um continuum maps of an essentially complete sample of the brightest 182 sub-millimetre sources (S_850um=6.2mJy) in COSMOS. Our ALMA maps detect 260 sub-millimetre galaxies (SMGs) spanning a range in flux density of S_870um=0.7-19.2mJy. We detect more than one SMG counterpart in 34+/-2 per cent of sub-millimetre sources, increasing to 53+/-8 per cent for SCUBA-2 sources brighter than S_850um>12mJy. We estimate that approximately one-third of these SMG-SMG pairs are physically associated (with a higher rate for the brighter secondary SMGs, S_870um>3mJy), and illustrate this with the serendipitous detection of bright [CII] 157.74um line emission in two SMGs, AS2COS0001.1 & 0001.2 at z=4.63, associated with the highest significance single-dish source. Using our source catalogue we construct the interferometric 870um number counts at S_870um>6.2mJy. We use the extensive archival data of this field to construct the multiwavelength spectral energy distribution of each AS2COSMOS SMG, and subsequently model this emission with MAGPHYS to estimate their photometric redshifts. We find a median photometric redshift for the S_870um>6.2mJy AS2COSMOS sample of z=2.87+/-0.08, and clear evidence for an increase in the median redshift with 870-um flux density suggesting strong evolution in the bright-end of the 870um luminosity function.

description: We examine radiatively driven mass loss from stars near and above the Eddington limit (Ledd). We begin by reviewing the instabilities that are expected to form extensive structure near Ledd. We investigate how this "porosity" can reduce the effective coupling between the matter and radiation. Introducing a new "porosity-length'' formalism, we derive a simple scaling for the reduced effective opacity, and use this to derive an associated scaling for the porosity-moderated, continuum-driven mass loss rate from stars that formally exceed Ledd. For a simple super-Eddington model with a single porosity length that is assumed to be on the order of the gravitational scale height, the overall mass loss is similar to that derived in previous porosity work. This is much higher than is typical of line-driven winds, but is still only a few percent of the photon tiring limit--for which the luminosity becomes insufficient to carry the flow out of the gravitational potential. To obtain still stronger mass loss that approaches observationally inferred values near this limit, we introduce a power-law-porosity model in which the associated structure has a broad range of scales. We show that the mass loss rate can be enhanced by a factor that increases with the Eddington parameter Gamma, such that for moderately large Gamma (> 3-4), mass loss rates could approach the photon tiring limit. Together with the ability to drive quite fast outflow speeds, the derived mass loss could explain the large inferred mass loss and flow speeds of giant outbursts in eta Carinae and other LBV stars.

The Renard 4 kimberlite : implications for ascent of kimberlites in the shallow crust
Creators: name: Gofton, Emma Lindsay
Publisher: name: University of British Columbia
Year: 2011

description: Kimberlite rock types that compose the Renard 4 kimberlite in northern Quebec, Canada, record the transition between the root and diatreme zones of a Class 1 kimberlite pipe. Analysis of lithologic textures and the componentry (clasts, macrocrysts and groundmass) of these rock types provides information pertinent to describing the evolution of the kimberlite pipe as well as to understanding the dynamics of its emplacement. This study defines six rock types present in the Renard 4 kimberlite. Five of these are kimberlitic. The rock types include two volcaniclastic facies, coherent kimberlite, transitional kimberlite and country rock breccia. The two volcaniclastic facies are: 1) a tufiisitic kimberlite breccia facies which is further subdivided into four phases and 2) an 'accretionary' magmaclastic facies. Coherent kimberlite is divided into two subfacies: 1) massive coherent macrocrystic kimberlite and 2) macrocrystic kimberlite breccia. The coherent breccia is a contact zone of the massive coherent kimberlite with the rock it intrudes and comprises non-kimberlitic clasts in a matrix of coherent kimberlite. A multi-stage emplacement process is invoked to account for the presence and the geometries of the Renard 4 rock units. Prior to the kimberlite eruption, coherent kimberlite dykes were emplaced. The eruption and filling of the diatreme were succeeded by emplacement of late-stage coherent kimberlite dykes and the emplacement of a late-stage volcaniclastic facies. Textures in the volcaniclastic facies as well as the juxtaposition of volcaniclastic, transitional and coherent rock types indicates that the present day surface of the Renard 4 kimberlite represents a level between the lower diatreme and the root zone of a Class 1 kimberlite pipe. It is proposed that concentration of country rock clasts occurred in areas of highest ascent velocity in the volcanic conduit. The presence of each of the Renard 4 rock types and their spatial distribution has important implications for the emplacement model of this kimberlite and provide important insight for general models pertaining to the formation of the root/diatreme transitional zone in other kimberlite pipes. The accretionary magmaclastic textures seen in some volcaniclastic rock types in Renard 4 indicates that fragmentation of the kimberlite magma occurs as deep as 2 kilometres below the earth surface and that during emplacement these magmas are inflated to many times the volume they currently occupy. It is furthermore suggested that the kimberlite magma is inflated, and the fragmental textures are formed in systems which may never have breached the surface.

description: In the U.S. 38% of total CO2 emissions come directly from the operation of buildings (not including their construction and demolition); even more than the 31% produced by the entire transportation industry each year, and this in a country with the 3rd highest cars per capita in the world. Additionally, 13.6% of the water and 71% of electricity usage flow into U.S. buildings; while 136 million tons of landfill come from the demolition and renovation of real estate projects each year. Still, in 2014 many people don-t even know what a green building or sustainable real estate means. Americans and Europeans spend on average 90% of their lives indoors. The quality of people-s lives is therefore largely related to the quality and habitability of the buildings in which they spend the vast majority of their time. This thesis will attempt to demonstrate the importance of minimizing the negative impact of the real estate sector on the environment and improving the quality of life for the users of buildings, as well as identify the most important factors relevant to increasing the market penetration of sustainable real estate through an examination of the evolution of several green building rating systems, and a number of other issues relating to human health and well-being.

Neural network satellite retrievals of nocturnal stratocumulus cloud properties

Publisher: name: University of British Columbia
Year: 2011

description: I investigate the feasibility of retrieving cloud top droplet effective radius, optical thickness and cloud top temperature of nocturnal marine stratocumulus clouds by inverting infrared satellite measurements using an artificial neural network. For my study, I use the information contained in the three infrared channels centred at 3.7, 11.0 and 12.0 μm of the Moderate Resolution Imaging Spectroradiometer (MODIS) on-board NASA ' s Terra satellite, as well as sea surface temperature. A database of simulated top-of-atmosphere brightness temperatures of a range of cloud parameters is computed using a correlated-k parameterisation which I have embedded in the radiative transfer package libRadtran. The database is used to train feed-forward neural networks of different architecture to perform the inversion of the satellite measurements for the cloud properties. I investigate the application of Bayesian methods to estimate the retrieval uncertainties, and analyse the Jacobian of the networks in order to gain information about the functional dependence of the retrieved parameters on the inputs. A high variability in the Jacobian indicates that the nocturnal retrieval problem is ill-posed. My experiments show that because the problem is ill-conditioned, it is very difficult to find a network that approximates the database of simulated brightness temperatures well. Sea surface temperature proves to be a necessary input. I compare the retrievals of a selected network architecture with in-situ cloud measurements taken during the second Dynamics and Chemistry of Marine Stratocumulus experiment. The results show general agreement between retrievals and in-situ observations, although no collocated comparsions are possible because of a time lag of five hours between both measurements. I establish that the uncertainty estimates are prone to numerical problems and their results are questionable. I show that the Jacobian is a valuable tool in evaluating the retrieval networks.

description: Magnetic Resonance Imaging (MRI) is a widely-accepted imaging technique for knee injury analysis. Its advantage of capturing knee structure in three dimensions makes it the ideal tool for radiologists to locate potential tears in the knee. In order to better confront the ever growing workload of musculoskeletal (MSK) radiologists, automated tools for patients' triage are becoming a real need, reducing delays in the reading of pathological cases. In this work, we present the Efficiently-Layered Network (ELNet), a convolutional neural network (CNN) architecture optimized for the task of initial knee MRI diagnosis for triage. Unlike past approaches, we train ELNet from scratch instead of using a transfer-learning approach. The proposed method is validated quantitatively and qualitatively, and compares favorably against state-of-the-art MRNet while using a single imaging stack (axial or coronal) as input. Additionally, we demonstrate our model's capability to locate tears in the knee despite the absence of localization information during training. Lastly, the proposed model is extremely lightweight ($

description: The travel cost method is widely used to estimate the value of recreational sites and to simulate the impact of public policies on welfare. Congestion is likely to be a determinant of recreational demand (Jakus and Shaw, 1997) and has to be given special attention. Ignoring this variable leads to the omission bias. But introducing congestion is also likely to involve endogeneity problems because of a potential correlation with the error term. In addition, congestion is determined by a sorting equilibrium, i.e., it is both the result of the choice process and an explanatory variable of this choice. Some methods have been recently propose to address these difficulties. These methods are presented and illustrated in a nested model of recreational choice.

description: The financial development of agricultural markets is not recent. But, starting early 2000, a large amount of investments on commodity markets, including agriculture, have been realized using innovative instruments. And in 2007-08, the continuous increase of investment was simultaneous with prices increases. Speculation and price spikes were soon “correlated”. A controversial debate on the role of commodity investment funds emerge that induced G-20 decision in November 2011 to limit excessive price volatility on commodity markets through improved control of speculation on futures and OTC markets. The article is analysing the hypothesis that commodity funds are causing price volatility using first a direct relationship between the “Assets Under Management” (AUM) of these funds and the agricultural futures prices, and second a sequential relationship between these variables through the commitment of commodity funds on related futures markets (open interest detained). As a conclusion, we validate the results of the two parties of the controversy. First, we do observe a significant causality of AUMs variability of commodity funds on price variability, but mainly from commodity index funds as opposed to “single-commodity” funds. That first result should bring implications on regulatory means. Second, we do not observe a significant causality of commodity funds commitments on futures markets. But we think that this absence of causality is mainly due to the low ability of the CFTC classification to inform on the real commitment of traders or/and due to the ability of commodity funds to hedge their price risk on the OTC market as a complement to the futures markets.

description: Cadmium (Cd) and arsenic (As) soil contamination poses significant problems for crop production worldwide. Zero-valent iron (Fe0) is a reactive material with reducing power capable of stabilizing toxic elements, including heavy metals and metalloids. In this study, we examined the effect of Fe0 application on Cd and As accumulation in spinach (Spinacia oleracea L.) grown in Cd- or As-contaminated soil. Fe0 soil application reduced Cd and As concentrations in spinach shoots and/or roots, and decreased their availability in soil, which may have affected their accumulation in spinach. Additionally, we examined the forms of soil Cd and As using the sequential extraction method. The potential availability of Cd and As forms in soils for plant root is: exchangeable > iron-manganese-oxide-bound > organic-matter-bound > free-oxide-occluded > residual. Fe0 application increased Cd and As distribution in the free-oxide-occluded fraction. Additionally, Fe0 application decreased As distribution in the iron-manganese-oxide-bound fraction while tended to decrease Cd in the organic-matter-bound fraction and increase it in the iron-manganese-oxide-bound fraction. Thus, Fe0 application can be effective in reducing Cd and As availability in their contaminated soils. Meanwhile, this study showed that Fe0 application inhibited the growth of spinach in Cd-contaminated soil. The unfavorable alterations caused by Fe0 in the contaminated soil should also be investigated in the future.

description: A state space based design method is given to find strongly stabilizing controllers for multiple-input-multiple-output plants (MIMO). A sufficient condition is derived for the existence of suboptimal stable H-infinity controller in terms of linear matrix inequalities (LMIs) and the controller order is twice that of the plant. A new parameterization of strongly stabilizing controllers is determined using linear fractional transformations (LFTs).

description: Motivated by a recent inelastic neutron scattering experiment on $\mathrm{YbMgGaO}_4$ \cite{William2019}, we reinvestigate the homogeneous spin model on the triangular lattice. Using the cluster mean-field theory, we study the phase diagram and the magnetic-field-induced phase transition. We find that the phase boundary between the stripe state and the $120^{\circ}$ antiferromagnetic state is broadened by the magnetic field, leading to a field-induced phase transition. This phase transition is suppressed by the next-nearest neighbor exchange interaction $J_2/J_1$ and vanishes as $J_2/J_1>0.13$. We find a parameter space at $J_2/J_1=0.1$, in which the field-induce transition can be achieved and the deviation of theoretical spin excitation energies from experimental data is only $5.4\%$. Our results imply that an effective homogeneous spin model still works in $\mathrm{YbMgGaO}_4$.

description: We examine the results linking cosmic ray flux (CRF) variations to global climate change. We then proceed to study various periods over which there are estimates for the radiative forcing, temperature change and CRF variations relative to today. These include the Phanerozoic as a whole, the Cretaceous, the Eocene, the Last Glacial Maximum, the 20th century, as well as the 11-yr solar cycle. This enables us to place quantitative limits on climate sensitivity to both changes in the CRF, Phi_CR, and the radiative budget, F, under equilibrium. Under the assumption that the CRF is indeed a climate driver, we find that the sensitivity to CRF variations is consistently fitted with mu := -Phi_0 (dT_global/ d Phi_CR) = 6.5 +/- 2.5 K (where Phi_0 is the CR energy flux today). Additionally, the sensitivity to radiative forcing changes is lambda := dT_global/ dF_0 = 0.35 +/- 0.09 K/(W/m^2), at the current temperature, while its temperature derivative is negligible with d lambda / dT_0 = 0.01 +/- 0.03 1/(W/m^2). If the observed CRF/climate link is ignored, the best sensitivity obtained is lambda = 0.54 +/- 0.12 K/(W/m^2) and d lambda / dT_0 = -0.02 +/- 0.05 1/(W/m^2). The CRF/climate link therefore implies that the increased solar luminosity and reduced CRF over the previous century should have contributed a warming of 0.37+/-0.13 K, while the rest should be mainly attributed to anthropogenic causes. Without any effect of cosmic rays, the increase in solar luminosity would correspond to an increased temperature of 0.16+/-0.04 K.

description: Simulations of turbulent fluid flow around long cylindrical structures are computationally expensive because of the vast range of length scales, requiring simplifications such as dimensional reduction. Current dimensionality reduction techniques such as strip-theory and depth-averaged methods do not take into account the natural flow dissipation mechanism inherent in the small-scale three-dimensional (3-D) vortical structures. We propose a novel flow decomposition based on a local spanwise average of the flow, yielding the spanwise-averaged Navier-Stokes (SANS) equations. The SANS equations include closure terms accounting for the 3-D effects otherwise not considered in 2-D formulations. A supervised machine-learning (ML) model based on a deep convolutional neural network provides closure to the SANS system. A-priori results show up to 92% correlation between target and predicted closure terms; more than an order of magnitude better than the eddy viscosity model correlation. The trained ML model is also assessed for different Reynolds regimes and body shapes to the training case where, despite some discrepancies in the shear-layer region, high correlation values are still observed. The new SANS equations and ML closure model are also used for a-posteriori prediction. While we find evidence of known stability issues with long time ML predictions for dynamical systems, the closed SANS simulations are still capable of predicting wake metrics and induced forces with errors from 1-10%. This results in approximately an order of magnitude improvement over standard 2-D simulations while reducing the computational cost of 3-D simulations by 99.5%.

description: We calculate the frequency-dependent mesoscopic acoustic phonon transmission probability through the abrupt junction between a semi-infinite, one-dimensional cylindrical quantum wire and a three-dimensional bulk insulator, using a perturbative technique that is valid at low frequency. The system is described using elasticity theory, and traction-free boundary conditions are applied to all free surfaces. In the low-frequency limit the transmission probability vanishes as the frequency squared, the transport being dominated by the longitudinal channel, which produces a monopole source of elastic radiation at the surface of the bulk solid. The thermal conductance between an equilibrated wire nonadiabatically coupled to a bulk insulator should therefore vanish with temperature at temperature cubed.

The productive path of Bioeconomy where this approach was applied is the Biodiversity Resource Exploitation. The study aim was to measure the level of environmental technical inefficiency over the body water of the Estero Real. We used a frontier stochastic model that it considers the environmental condition with chemical and physic parameters and the planetary magnetic activity. The environmental inefficiency effects were assumption to be an independent distribution as truncations of normal distributions with constant variance, but means, which are a linear function of observable Sampling Point-specific variables. The results show that environmental inefficiency effects are understandable by inelasticity solar activity (-2.53) that reduce the quality water in 89 %, it imply according to Lynch y Poole (1979) a regular quality.

description: Los flóculos son bioalimentos importantes en la economía de cultivos acuícolas, presentan bajos costos y tienen bajo impacto ecológico. Este trabajo se realizó con el objetivo de diferenciar los efectos en el crecimiento de los camarones aplicando flóculos como suplemento alimenticio o sin flóculo. Para esto se midieron el Oxígeno disuelto, Temperatura, Salinidad, Crecimiento acumulado, Ritmos de crecimiento, cantidad de flóculo administrado. Como resultados se obtuvieron que el Oxígeno Disuelto varió entre 9.7 a 3.6 mg/l. La Temperatura se presentó entre los intervalos de 31.7 °C a 26.4 °C y La Salinidad entre 26 a 28°/ooS y la pila sin floculo entre 26 a 30 °/ooS. Los animales alimentados con complemento de flóculo crecieron 2g/30días y de 1,6g/30días los que no se aplicó flóculo, el Ritmo de Crecimiento presentó 0,38g/30días y de 0,30g/30días los que no se aplicó flóculo y una sobrevivencia de 98% para la pila con flóculo y 91% para la pila que no se aplicó flóculo. Se encontraron 0.8 a 1,2 millones flóculos/ml, la tendencia de las poblaciones de flóculo observado fue en incremento a lo largo del tiempo. Se obtuvieron diferencias significativas entre el crecimiento de los camarones en ambos tratamientos. (p<0.05)

description: Last year's X(3872) discovery was confirmed with the CDF II detector in pbarp collisions. We measure its mass to be $3871.3 \pm 0.7 \pm 0.4 MeV/c2$. The source of X-mesons in the large CDF sample is resolved by studying their vertex displacement. We find $16.1 \pm 4.9 \pm 2.0$% of our X-sample comes from decays of b-hadrons, and the remainder from prompt sources: either direct production or by decay of (unknown) short-lived particles. The mix of production sources is similar to that observed for the psi(2S) charmonium state.

description: Die vorliegende Arbeit beleuchtet das Thema Behinderung in Integrationsklassen. Sie zeigt auf, wie Heilpädagoginnen des Kantons Zürich mit dem Thema Behinderung umgehen und wie sie es in Integrationsklassen aufgreifen. Diese Arbeit soll Anregung dazu geben, sich selbst in Bezug auf das Thema Behinderung und die Umsetzung in der Schule zu reflektieren und einen kompetenten Umgang damit zu finden. Die Daten wurden mittels Leitfadeninterviews mit im Kanton Zürich tätigen Heilpädagoginnen erhoben und mithilfe einer Kombination von deduktivem und induktivem Kategoriensystem ausgewertet. Die Ergebnisse zeigen auf, dass die befragten Heilpädagoginnen auf die drei Bereiche Reflexion, soziales Netz und Pädagogik zurückgreifen um eine Thematisierung anzugehen.

Subsolar Al/Si and Mg/Si ratios of non-carbonaceous chondrites reveal planetesimal formation during early condensation in the protoplanetary disk

description: The Al/Si and Mg/Si ratios in non-carbonaceous chondrites are lower than the solar (i.e., CI-chondritic) values, in sharp contrast to the non-CI carbonaceous meteorites and the Earth, which are enriched in refractory elements and have Mg/Si ratios that are solar or larger. We show that the formation of a first generation of planetesimals during the condensation of refractory elements implies the subsequent formation of residual condensates with strongly sub-solar Al/Si and Mg/Si ratios. The mixing of residual condensates with different amounts of material with solar refractory/Si element ratios explains the Al/Si and Mg/Si values of non-carbonaceous chondrites. To match quantitatively the observed ratios, we find that the first-planetesimals should have accreted when the disk temperature was ~1,330-1,400 K depending on pressure and assuming a solar C/O ratio of the disk. We discuss how this model relates to our current understanding of disk evolution, grain dynamics, and planetesimal formation. We also extend the discussion to moderately volatile elements (e.g., Na), explaining how it may be possible that the depletion of these elements in non-carbonaceous chondrites is correlated with the depletion of refractory elements (e.g., Al). Extending the analysis to Cr, we find evidence for a higher than solar C/O ratio in the protosolar disk's gas when/where condensation from a fractionated gas occurred. Finally, we discuss the possibility that the supra-solar Al/Si and Mg/Si ratios of the Earth are due to the accretion of ~40% of the mass of our planet from the first-generation of refractory-rich planetesimals.

The systematics and paleobiology of Hettangian ammonites from the allochthonous terranes of British Columbia
Creators: name: Longridge, Louise M.
Publisher: name: University of British Columbia
Year: 2011

description: The Hettangian is a poorly understood 3 million year time interval following the Triassic-Jurassic mass extinction during which the biosphere struggled to rebuild its diversity. Hettangian ammonite faunas are examined from the two key areas of the terranes of British Columbia, Taseko Lakes and the Queen Charlotte Islands (QCI). In total, 90 different species or taxonomic groups are described representing 32 genera. Thirteen new species are recognized. Stratigraphic ranges are identified for each taxon and the North American Zonation is updated so that it is more representative of Canadian sequences. Except for the definitive occurrence of the Spelae Zone, all Hettangian zones of the North American Zonation are present in the BC terranes. A section on Kunga Island in the QCI demonstrates a spectacular radiolarian turnover across the Triassic-Jurassic transition interval (T-J boundary), provides a radiometric date to constrain the boundary, contains ammonites which permit correlations with other areas and can be correlated with a carbon curve which shows a distinct negative excursion just below the radiolarian turnover. This section is proposed as a potential Global Stratotype Section and Point for the basal Jurassic if radiolarians are selected as the primary standard for defining the T-J boundary or as a parastratotype section to assist with characterizing the interval if radiolarians are not selected. Detailed correlations are suggested between the Hettangian and lower Sinemurian of the terranes and other areas of North America, South America, New Zealand, western and eastern Tethys, and northwest Europe. The lateral distribution of ammonite faunas suggest there may have been some longitudinal separation between the craton and the Cadwallader, Wrangellia and Peninsular terranes during the Hettangian. They also support a significant northward displacement for Wrangellia relative to the craton since Early Jurassic time and suggest that the Hispanic Corridor connecting the Panthalassa and Tethys oceans may have been open during the Hettangian. Sexual dimorphism is recognized in several Hettangian genera including Kammerkarites, Eolytoceras, Sunrisites and Badouxia. Asymmetries in the vertical position of the internal elements of the phragmocone of B. columbiae were assessed for a potential counterbalance mechanism using computer modeling. No counterbalance mechanism was recognized.

description: We present initial results from the \textit{COS and Gemini Mapping the Circumgalactic Medium} (\mbox{CGMCGM} $\equiv$ CGM$^{2}$) survey. The CGM$^{2}$ survey consists of 1689 galaxies, all with high-quality Gemini GMOS spectra, within 1 Mpc of twenty-two $z \lesssim 1$ quasars, all with S/N$\sim$10 {\emph{HST/COS}} G130M$+$G160M spectra. For 572 of these galaxies having stellar masses $10^{7} M_{\odot} < M_{\star} < 10^{11} M_{\odot}$ and $z \lesssim 0.5$, we show that the \ion{H}{1} covering fraction above a threshold of \NHI$>10^{14} $cm$^{-2}$ is $\gtrsim 0.5$ within 1.5 virial radii ($R_{\rm vir} \sim R_{200m}$). We examine the \ion{H}{1} kinematics and find that the majority of absorption lies within $\pm$ 250 km s$^{-1}$ of the galaxy systemic velocity. We examine \ion{H}{1} covering fractions over a range of impact parameters to infer a characteristic size of the CGM, $R^{14}_{\rm CGM}$, as a function of galaxy mass. $R^{14}_{\rm CGM}$ is the impact parameter at which the probability of observing an absorber with \NHI $>$ 10$^{14}$ cm$^{-2}$ is $>$ 50\%. In this framework, the radial extent of the CGM of $M_{\star} > 10^{9.9} M_{\odot}$ galaxies is $R^{14}_{\rm CGM} = 346^{+57}_{-53}$ kpc or $R^{14}_{\rm CGM} \simeq 1.2R_{\rm vir}$. Intermediate-mass galaxies with $10^{9.2} < M_{\star}/M_{\odot} < 10^{9.9}$ have an extent of $R^{14}_{\rm CGM} = 353^{+64}_{-50}$ kpc or $R^{14}_{\rm CGM} \simeq 2.4R_{\rm vir}$. Low-mass galaxies, $M_{\star} < 10^{9.2} M_{\odot}$, show a smaller physical scale $R^{14}_{\rm CGM} = 177_{-65}^{+70}$ kpc and extend to $R^{14}_{\rm CGM} \simeq 1.6R_{\rm vir}$. Our analysis suggests that using $R_{\rm vir}$ as a proxy for the characteristic radius of the CGM likely underestimates its extent.
