description: We present the latest version of the ray-tracing simulation code Skylens, which can be used to develop image simulations that reproduce strong lensing observations by any mass distribution with a high level of realism. Improvements of the code with respect to previous versions include the implementation of the multi-lens plane formalism, the use of denoised source galaxies from the Hubble eXtreme Deep Field, and the simulation of substructures in lensed arcs and images, based on a morphological analysis of bright nearby galaxies. Skylens can simulate observations with virtually any telescope. We present examples of space- and ground-based observations of a galaxy cluster through the Wide Field Channel on the Advanced Camera for Surveys of the Hubble Space Telescope, the Near Infrared Camera of the James Webb Space Telescope, the Wide Field Imager of the Wide Field Infrared Survey Telescope, the Hyper Suprime Camera of the Subaru telescope, and the Visible Imaging Channel of the Euclid space mission.

Foundations of sustainable resource management: the legitimation function
Creators: name: Lavers, Anthony
Publisher: name: Imperial College London
Year: 2015

description: The literature on management of common-pool resources and social-ecological systems is extensive. It covers at least 40 years of research. In that time, significant progress has been made in understanding the conditions and factors that characterise sustainable management schemes, particularly community-based schemes. This thesis attempts to build on this literature. Its core concern and unifying theme is the ‘factors’ that explain why some management systems are successful and others are not. Of course, the list of factors identified in existing literature is extensive. Some of these factors - socio-economic heterogeneity, for instance - are explored in significant depth. This thesis does not propose to contribute to our understanding of such factors. Instead, it focuses on one factor – legitimacy – which is recognised as important by a large number of researchers, but has been subject to only limited investigation in the field. The thesis adopts a multi-disciplinary and mixed methods approach to ask how resource management systems - and the organisations that design and operate them - gain legitimacy. Much of the research is based on two case studies of resource management systems in Argentina and the United States. One of these systems is in the process of being implemented, but has been the source of much dissatisfaction to date. The other system, a fisheries management plan, was introduced in 1995, and has changed the fortunes of fishermen and other stakeholders in mostly positive ways. These case studies are the point of departure for developing a more complete picture of the factors that underpin legitimacy in resource management contexts.

Emulsion-based supracolloidal materials stabilized by specifically designed branched copolymers
Creators: name: Bell, Robert Valentine
Publisher: name: Imperial College London
Year: 2015

description: The possible applications of branched copolymers are far reaching because of their various combinations of functionality and architectural diversity. More importantly, the domains and chain-end functionalities of the branched copolymers can be readily varied, via the simple and scalable Strathclyde route, to optimize/tailor the properties of the polymers for a specific application by careful choice of monofunctional monomers, branching monomers, and chain transfer agents. In the present thesis, branched copolymers were utilized as emulsifying agents for the production of oil-in-water emulsion droplets. These emulsion droplets were used as a platform to create novel emulsion-based supracolloidal materials. The chemical composition and architectural structure of the branched copolymers were specifically chosen to create stable emulsions and provide the correct functionalities required for the application. Calcium phosphate (CaP) microcapsules were fabricated by utilizing oil-in-water emulsion droplets, stabilized with branched copolymer, as templates. The branched copolymer was designed to provide a suitable architecture and functionality to produce stable emulsion droplets, and permit the mineralization of CaP at the surface of the oil droplet. These CaP capsules were made fluorescent by post-functionalization of the CaP shell with a fluorescent conjugate. Oil-in-water emulsion droplets stabilized with Laponite clay disc functionalized with pH-responsive branched copolymers were microfluidically spun into supracolloidal fibers. These supracolloidal fibers can be used as a tool to delivery volatile compounds in a time-controlled manner. The dried fibers created were low-weight porous materials. It was also discovered that these supracolloidal fibers can be utilized as a storage material for emulsion droplets, where emulsion droplets are ‘locked’ in the fiber structure under acidic condition, and are released from the fiber upon basification of the system. The release of emulsion droplets from the fiber can be time-controlled by programming the transient acidic pH states of the system by combining a fast acidic promoter with a feedback-driven biocatalytically controlled slow generation of base in a close system.
Are the Luminosities of RR Lyrae Stars Affected by Second Parameter Effects?

description: There is a serious discrepancy between the distance to the LMC derived from the Cepheid Period-Luminosity relation and that obtained by using the Galactic calibration for the luminosity of RR Lyrae stars. It is suggested that this problem might be due to the fact that second parameter effects make it inappropriate to apply Galactic calibrations to RR Lyrae variables in the Magellanic Clouds, i.e. Mv(RR) could depend on both [Fe/H] and on one or more second parameters.

description: Massive growth of the microfluidics field has triggered numerous advances in focusing, separating, ordering, concentrating, and mixing of microparticles. Microfluidic systems capable of performing these functions are rapidly finding applications in industrial, environmental, and biomedical fields. Passive and label-free methods are one of the major categories of such systems that have received enormous attention owing to device operational simplicity and low costs. With new platforms continuously being proposed, our aim here is to provide an updated overview of the state of the art for passive label-free microparticle separation, with emphasis on performance and operational conditions. In addition to the now common separation approaches using Newtonian flows, such as deterministic lateral displacement, pinched flow fractionation, cross-flow filtration, hydrodynamic filtration, and inertial microfluidics, we also discuss separation approaches using non-Newtonian, viscoelastic flow. We then highlight the newly emerging approach based on shear-induced diffusion, which enables direct processing of complex samples such as untreated whole blood. Finally, we hope that an improved understanding of label-free passive sorting approaches can lead to sophisticated and useful platforms toward automation in industrial, environmental, and biomedical fields.
Radiative Transfer in a Clumpy Universe: III. The Nature of Cosmological Ionizing Sources

description: The history of the transition from a neutral intergalactic medium (IGM) to one that is almost fully ionized can reveal the character of cosmological ionizing sources. We study the evolution of the volume filling factor of HII and HeIII regions in a clumpy IGM, and discuss the implications for rival reionization scenarios of the rapid decline in the space density of radio-loud quasars and of the large population of star-forming galaxies recently observed at z>3. The hydrogen component in a highly inhomogeneous universe is completely reionized when the number of photons emitted above 1 ryd in one recombination time equals the mean number of hydrogen atoms. If stellar sources are responsible for keeping the IGM ionized at z=5, the rate of star formation at this epoch must be comparable or greater than the one inferred from optical observations of galaxies at z=3, and the mean metallicity per baryon in the universe of order 1/500 solar. An early generation of stars in dark matter halos with circular velocities v_circ=50 km/s, possibly one of the main source of UV photons at high-z, could be detectable with the Next Generation Space Telescope. Models in which the quasar emissivity declines rapidly at z>3 predict a late HeII reionization epoch, a feature that could explain the recent detection of patchy HeII Lyman-alpha at z=2.9 by Reimers et al. (1997) and the abrupt change observed by Songaila (1998) at about the same epoch of the SiIV/CIV ratio, but appear unable to provide the required number of hydrogen-ionizing photons at z=5.

description: Early-type dwarf galaxies are found to have high specific globular cluster frequencies which are similar to the high S values that are observed in luminous galaxies of types E and S0. It appears unlikely that cluster formation during mergers between dwarf disk systems can account for the high specific globular cluster frequency that is observed in early-type dwarf galaxies. Some alternative scenarios are briefly discussed.

description: Mutation rate is a key determinant of the pace as well as outcome of evolution, and variability in this rate has been shown in different scenarios to play a key role in evolutionary adaptation and resistance evolution under stress caused by selective pressure. Here we investigate the dynamics of resistance fixation in a bacterial population with variable mutation rates and show that evolutionary outcomes are most sensitive to mutation rate variations when the population is subject to environmental and demographic conditions that suppress the evolutionary advantage of high-fitness subpopulations. By directly mapping a biophysical fitness function to the system-level dynamics of the population we show that both low and very high, but not intermediate, levels of stress in the form of an antibiotic result in a disproportionate effect of hypermutation on resistance fixation. We demonstrate how this behavior is directly tied to the extent of genetic hitchhiking in the system, the propagation of high-mutation rate cells through association with high-fitness mutations. Our results indicate a substantial role for mutation rate flexibility in the evolution of antibiotic resistance under conditions that present a weak advantage over wildtype to resistant cells.

description: Six BL Lac objects from the complete 1 Jy radio-selected sample of 34 objects were observed in Cycle 5 with the HST WFPC2 camera to an equivalent limiting flux of mu_I~26 mag/arcsec^2. Here we report results for the second half of this sample, as well as new results for the first three objects, discussed previously by Falomo et al. (1997). In addition, we have analyzed in the same way HST images of three X-ray-selected BL Lacs observed by Jannuzi et al. (1997). The ensemble of 9 BL Lac objects spans the redshift range from z=0.19 to ~1. Host galaxies are clearly detected in seven cases, while the other two, at z~0.258 (redshift highly uncertain) and z=0.997, are not resolved. The HST images constitute a homogeneous data set with unprecedented morphological information between a few tenths of an arcsecond and several arcseconds from the nucleus, allowing us in 6 of the 7 detected host galaxies to rule out definitively a pure disk light profile. The host galaxies are luminous ellipticals with an average absolute magnitude of M_I~-24.6 mag (with dispersion 0.7 mag), more than a magnitude brighter than L* and comparable to brightest cluster galaxies. The morphologies are generally smooth and have small ellipticities (epsilon<0.2). Given such roundness, there is no obvious alignment with the more linear radio structures. In the six cases for which we have HST WFPC2 images in two filters, the derived color profiles show no strong spatial gradients and are as expected for K-corrected passively evolving elliptical galaxies. The host galaxies of the radio-selected and X-ray-selected BL Lacs for this very limited sample are comparable in both morphology and luminosity.

Two-phase flow behaviour and relative permeability between CO2 and brine in sandstones at the pore and core scales
Creators: name: Reynolds, Catriona Anne
Publisher: name: Imperial College London
Year: 2016

description: In this thesis we have performed an experimental investigation into steady-state two-phase flow behaviour at the core and pore scales and visualised the fluid distributions using medical and fast synchrotron X-ray computed tomography. We performed an experimental study of steady-state, drainage relative permeability curves with CO2-brine and N2-deionised water, on a single Bentheimer sandstone core with a simple two-layer heterogeneity over reservoir conditions of 10.3-20.7 MPa, 38-91°C and 0-5 mol kg-1 NaCl brine. We demonstrate that, if measured in the viscous limit, relative permeability is invariant with changing reservoir conditions, and is consistent with the continuum-scale multiphase flow theory for water wet systems. Furthermore, we show that under capillary limited conditions, the CO2-brine system is very sensitive to heterogeneity in capillary pressure, and by performing core-floods under capillary limited conditions, we produce effective relative permeability curves that are flow rate and fluid parameter dependent. We show that the appropriate conditions for measuring intrinsic or effective relative permeability curves can be selected simply by scaling the driving force for flow by a quantification of capillary heterogeneity and use this methodology to make measurements of CO2-brine relative permeability for target CO2 storage reservoirs in the UK. A new type of pore-scale flow behaviour was identified, that we term dynamic connectivity, using fast synchrotron X-ray computed tomography to image the capillary dominated steady-state flow of N2 and 1.5 mol kg-1 KI brine at 50°C and 10 MPa. Non-wetting phase flow occurred via a stable connected pathway at low capillary numbers and through a series of transient connections between a network of static ganglia with a dynamic connectivity at increasing capillary numbers. We speculate that changes observed in the strength and character of hysteresis between drainage and imbibition during capillary and viscous dominated core-scale experiments is a consequence of this pore-scale flow mechanism.

description: Modeling flow through porous media with multiple pore-networks has now become an active area of research due to recent technological endeavors like geological carbon sequestration and recovery of hydrocarbons from tight rock formations. Herein, we consider the double porosity/permeability (DPP) model, which describes the flow of a single-phase incompressible fluid through a porous medium exhibiting two dominant pore-networks with a possibility of mass transfer across them. We present a stable mixed discontinuous Galerkin (DG) formulation for the DPP model. The formulation enjoys several attractive features. These include: (i) Equal-order interpolation for all the field variables (which is computationally the most convenient) is stable under the proposed formulation. (ii) The stabilization terms are residual-based, and the stabilization parameters do not contain any mesh-dependent parameters. (iii) The formulation is theoretically shown to be consistent, stable, and hence convergent. (iv) The formulation supports non-conforming discretizations and distorted meshes. (v) The DG formulation has improved element-wise (local) mass balance compared to the corresponding continuous formulation. (vi) The proposed formulation can capture physical instabilities in coupled flow and transport problems under the DPP model.

A search for supersymmetry in $\sqrt{s}=13~\tev$ proton-proton collisions with the CMS detector at the LHC
Creators: name: Elwood, Adam
Publisher: name: Imperial College London
Year: 2017

description: An inclusive search for supersymmetry with jets and missing transverse energy is presented. Data from √s = 13 TeV pp-collisions with a total integrated luminosity of 12.9 fb^(−1) delivered by the LHC and collected by the CMS detector are analysed. The dominant quantum chromodynamic multijet background is strongly suppressed with several kinematic variables, which are also used to discriminate between Standard Model and supersymmetric processes. The observed events are found to be compatible with the expected contributions from Standard Model processes. This result is interpreted in the context of simplified supersymmetric models of gluino and third-generation squark production. The mass of the gluino, bottom squark and top squark are excluded to 1775, 1025 and 875 GeV respectively. In preparation for the collection of √s = 13 TeV data by CMS, the jet algorithm for the Level-1 trigger is upgraded. The new algorithm allows for dynamic pileup subtraction and takes advantage of hardware upgrades to the trigger. The performance of different types of pileup subtraction are evaluated and the most promising algorithm, chunky-donut subtraction, is chosen. The algorithm is found to give a significant performance improvement and has been used to collect data from 2016 onwards.
Searches for neutral Higgs bosons in final states with two tau leptons using the CMS detector
Creators: name: De Wit, Adinda Maite
Publisher: name: Imperial College London
Year: 2017

description: The Compact Muon Solenoid (CMS) detector is a general-purpose detector located at the Large Hadron Collider at CERN. It was designed to test the predictions of the standard model and to search for the Higgs boson in addition to searches for new physics beyond the standard model. The analyses presented in this thesis are searches for neutral Higgs bosons with tau leptons in the final state. These searches use proton-proton collision data recorded by CMS during 2012, 2015 and 2016. The searches are performed in the context of the minimal supersymmetric standard model (MSSM). One of the analyses, using 19.7 fb-1 of data collected during 2012 at √s = 8 TeV, is a search for a heavy neutral Higgs boson decaying into two 125 GeV Higgs bosons with standard model-like properties, with two b-quarks and two tau leptons in the final state. The other analyses use 2.3 fb−1 of data collected during 2015 and 12.9 fb−1 of data collected during 2016, both at √s = 13 TeV. These are searches for neutral MSSM Higgs bosons in the mass range of 90 GeV–3.2 TeV directly decaying into pairs of tau leptons. No significant excess is observed in any of the searches. Upper limits at the 95% confidence level are set on the cross section times branching ratio for the production of Higgs bosons in the MSSM. In addition, limits are set in the mA-tanβ parameter space of several MSSM benchmark scenarios, and in the cos (β − α)-tan β parameter space of a two Higgs doublet model.

description: Porphyriops melanops
Porphyriops melanops es una gallineta suramericana, con un peso adulto aproximado entre 154 y 225 g. La coloración de los adultos es gris en la parte inferior, cuello y cabeza; la cara y frente son negruzcas y los flancos marrones con manchas blancas, las alas y la espalda castaño, abdomen y coberteras infracaudales blancas. Las patas son verdosas, el pico es verde claro llamativo, los ojos rojos. Se distribuye desde los Andes orientales colombianos hasta el sur de Suramérica (Taylor 1996). Se encuentran en humedales naturales y artificiales en donde se alimentan de vegetación y pequeños invertebrados. Las poblaciones colombianas constituyen una subespecie endémica (P. m. bogotensis), aislada cerca de 3000 km de las más cercanas que se encuentran en Bolivia y Brasil (Taylor 1996). En Colombia, en donde se reproduce a lo largo de todo el año (Rosselli et al. 2016), P. m. bogotensis se restringe a los humedales del altiplano Cundiboyacense entre los 2500 y 3100 m; estos ecosistemas han disminuido en más del 97 % y están altamente transformados, lo que ha llevado a que la subespecie colombiana se encuentre amenazada y categorizada En Peligro (Renjifo et al. 2016).

description: This thesis investigates how information on Canadian food packaging can be made accessible to people with vision impairments. Accessible packaging will allow them to shop for groceries independently, make informed purchase decisions, and use the products more efficiently. This thesis uses two approaches. One was to redesign existing food labels to make them accessible to people with mild or moderate vision impairment through the appropriate use of typography, color, images, illustrations, and patterns. The second approach focuses on the addition of Braille and a text to speech feature to meet the needs of people with a severe vision impairment or blindness. Along with accessibility, the aesthetic appeal of the packaging has been a critical consideration throughout the research. Communication design based studio explorations form the core of this thesis. Other methods such as observation, precedent review, personal reflection, case studies, literature review, and interviews with visually impaired participants, experts, and design professionals drive the explorations. The final outcome of the research is a prototype of a sample accessible grocery food brand with a variety of products. Considerations and challenges that shaped the prototypes are also discussed. The research provides a resource for designers and businesses within and outside Canada interested in working within the field of accessible grocery food packaging.

description: We introduce a stochastic agent-based model for the flocking dynamics of self-propelled particles that exhibit velocity-alignment interactions with neighbours within their field of view. The stochasticity in the dynamics of the model arises purely from the uncertainties at the level of interactions. Despite the absence of attractive forces, this model gives rise to a wide array of emergent patterns that exhibit long-time spatial cohesion. In order to gain further insights into the dynamical nature of the resulting patterns, we investigate the system behaviour using an algorithm that identifies spatially distinct clusters of the flock and computes their corresponding angular momenta. Our results suggest that the choice of field of view is crucial in determining the resulting emergent dynamics of stochastically interacting particles.

The magnification invariant of simple galaxy lens models

description: We demonstrate that for several of the gravitational lens models used to describe galaxies, there exists a quantity we dub the magnification invariant, equaling the sum of the signed magnifications of the images, that is a constant when the image multiplicity is a maximum. This invariant is independent of most of the model parameters, and is independent of the source position as long as the source lies inside the caustic. It is not necessary to solve the lens equations to compute this invariant. For quad lenses, it is usually easy to assign image parities and thus one can compute the sum of the signed fluxes, compare with the magnification invariant of different models, and infer the model magnification factors of the images without fitting. We evaluate the invariant for simple galaxy models, apply it to known cases of quadruple lenses, and discuss implications for the ability of these lens models to reproduce observed image brightnesses.

The β-effect in tropical cyclones: impact on intensity and sensitivity to temperature
Creators: name: Corsaro, Carlo Maria
Publisher: name: Imperial College London
Year: 2017

description: Tropical cyclones are large weather systems whose development is characterised by complex physical processes that are not yet fully understood. A better understanding of how cyclones work is vital to help forecasters make more accurate predictions. The objective of this study is to contribute to the understanding of the track and intensity evolution in relation to the β-effect. While the β-effect has been widely studied, its response to changes in environmental conditions has been investigated only marginally. To this end a series of idealised experiments using the Weather Research and Forecasting model is performed. The sensitivity of the β-drift is investigated with no background flow by changing uniformly sea surface and atmospheric temperature. With increasing temperature tropical cyclones become more intense, larger and move faster with a stronger westward deflection. In particular, there is a linear relationship between the β-drift speed and size above a gale-force wind radius of 250 km. Another aspect investigated is the impact of the β-effect on cyclone intensity. A comparison between an experiment with variable Coriolis parameter f and one on an f -plane shows that after the initial intensification the former has a lower intensity and undergoes a weakening not present in the latter. The main reason behind this weakening is the dry intrusion of a mid-upper tropospheric westerly flow. Back-trajectories show that the intrusion originates from the anticyclonic recirculation of the air expelled from the cyclone deep convection at earlier times, eventually causing a self-weakening of the cyclone. A real-case simulation of Hurricane Katrina (2005) and two sensitivity experiments are performed to investigate the results of the idealised simulations. The occurrence of both the β-drift sensitivity to temperature and the dry intrusion further demonstrates that the results presented here might contribute to the general understanding of the intensity and track evolution of tropical cyclones.
Analytical Models For Galactic Nuclei

description: I present a general family of dynamical models with simple analytical potential-density pairs suited to model galactic bulges and nuclei with double power-law radial density profiles and an optional central black hole. Analytical expressions for the potential and velocity dispersion of these models are given in the spherical case. Many previously known analytical spherical models, including also the recent $γ/ η$-models by Dehnen (1993) and Tremaine et al. (1994), are special cases of this family. This family also forms a complete set for constructing general galaxy models or solving Poisson's equation in the non-spherical case. In particular, a generalized Clutton-Brock (1973) and Hernquist-Ostriker (1992) orthogonal basis set is given.

description: We calculate the all-sky number of galaxy clusters that are expected to be gravitationally lensed by foreground massive clusters. We describe the redshift and number distributions of clusters using a Press-Schechter analysis, and model the foreground lensing clusters as singular isothermal spheres. If Omega_m=0.3 and Omega_Lambda=0.7, we expect ~ 30 cluster-cluster strong lensing events that involve foreground X-ray luminous clusters with total mass greater than 7.5 x 10^14 h^-1 M_sun, or X-ray luminosity L_x (2-10 keV) 8 x 10^44 h^-2 ergs s^-1, and background clusters with total mass greater than 10^14 h^-1 M_sun. The number expected in an open universe with Omega_m = 0.3 is less than \~ 4. Because of uncertainty in sigma_8, the root-mean-square density fluctuations in spheres of radius 8 h^-1 Mpc, the exact number of such lensing events is uncertain by a factor of about 5. We examine methods to detect cluster-cluster lensing events based on optical, X-ray, and Sunyaev-Zel'dovich effect observations.

Dense 3D facial shape recovery employing shading and correspondences
Creators: name: Snape, Patrick
Publisher: name: Imperial College London
Year: 2017

description: Human faces are one of the most frequently captured objects in both videos and photographs due to their fundamental role in communication and social interactions. The variability of this facial imagery makes it difficult to automate the understanding of scenes containing faces under unconstrained conditions. For faces, recovering accurate dense 3D facial shape from images and videos enables much richer understanding of the human face and its interaction with the scene. In this thesis, we seek to extend the work in the area of dense 3D facial shape recovery under challenging unconstrained conditions. There are a wealth of ways to recover 3D shape from images and videos, all of which make specific assumptions about the relationship between the individual images and the construction of the scene. Given this broad selection of methods available, we examine three different scenarios for dense 3D facial shape recovery: i) recovery from a single image, ii) recovery from an unconstrained image collection without any explicit 3D shape priors and iii) recovery from a video sequence. We focus on these three cases and show how facial priors can be introduced to tackle the dense 3D facial surface recovery problem. We propose to investigate the use of shading constraints for dense shape recovery from unconstrained images. Given the challenging nature of these images, the introduction of priors greatly improves performance over the generic shape-from-shading literature. However, the introduction of explicit priors comes with a further problem, that of correspondence. That is, recovering the relationship between pixels in the image and the structure of our model. For this reason, we also investigate the importance of finding dense correspondences between facial images. We show that it is possible to recover plausible dense 3D facial surfaces under a variety of different input conditions.

description: Approximate Bayesian Computation (ABC) is typically used when the likelihood is either unavailable or intractable but where data can be simulated under different parameter settings using a forward model. Despite the recent interest in ABC, high-dimensional data and costly simulations still remain a bottleneck in some applications. There is also no consensus as to how to best assess the performance of such methods without knowing the true posterior. We show how a nonparametric conditional density estimation (CDE) framework, which we refer to as ABC-CDE, help address three nontrivial challenges in ABC: (i) how to efficiently estimate the posterior distribution with limited simulations and different types of data, (ii) how to tune and compare the performance of ABC and related methods in estimating the posterior itself, rather than just certain properties of the density, and (iii) how to efficiently choose among a large set of summary statistics based on a CDE surrogate loss. We provide theoretical and empirical evidence that justify ABC-CDE procedures that {\em directly} estimate and assess the posterior based on an initial ABC sample, and we describe settings where standard ABC and regression-based approaches are inadequate.

description: We report redshifts in two gravitational lens systems, MG0414+0534 and MG0751+2716. The lens galaxy in MG0414+0534 lies at z_l=0.9584+/-0.0002. The luminosity and extreme red color of the lens are then typical of a passively evolving, early-type, ~2L* galaxy. The galaxy cannot have a significant global mean extinction without being anomalously luminous. The lens galaxy in MG0751+2716 has a redshift of z_l=0.3502+/-0.0003 and it is a member of a small group. The group includes the nearby, bright companion galaxy whose redshift we confirmed to be z=0.3501+/-0.0001 and a nearby emission line galaxy with z=0.3505+/-0.0003. A second emission line galaxy with z=0.5216+/-0.0001 was found nearly superposed on the first emission line galaxy. The source in MG0751+2716 is a z_s=3.200+/-0.001 radio quasar. For flat universes with Omega_0=1.0 (0.3), 96% (87%) of lenses like MG0414+0534 and 7% (3%) of lenses like MG0751+2716 are expected to have lower lens redshifts than observed.

description: Research shows formative assessments substantially strengthen learning and support summative assessment/evaluation practices. These practices are not widely applied in ATE's professional development (PD) efforts. This study focuses on participant teachers' assessment involvement to increase student learning and enhance outcome evaluations. We surveyed all principal investigators of ATE projects in 2022 who applied assessments in their 2021 PD efforts (N=70). Findings show that a minority of PD efforts apply formative assessment practices to strengthen PD outcomes or meet ATE's evaluation specifications. Assessment practices were most prevalent for summative purposes at the close of PD activity; a large majority assessed teachers' interest and learning in the PD and their intentions to use and teach what was learned on return to their classrooms. A third or less followed up to assess outcomes in teachers' schools. Similarly, thirty percent or less addressed matters of context at any stage of the PD efforts, and a few, 11 percent, followed up to assess the context in the schools. Concomitantly, the findings show where and how attention to formative assessment in the PD learning process can increase teacher involvement in assessment practices, making PD instruction more effective and strengthening outcome evaluations in participant teachers' home classrooms.
