title: Thin Film Perovskite Solar Cells: Fabrication via Spin Coating, Flash Evaporation and Chemical Vapor Deposition (CVD)
Creators: name: Claudiu, Mortan
Publisher: name: UNSPECIFIED
Year: 2020

description: In this work, thin film perovskite solar cells with different compositions have been manufactured with the help of the methods: spin coating, spray pyrolysis, etching, sputtering, chemical bath deposition, flash evaporation and chemical vapor deposition (CVD). The solar cells and their materials have been characterized electrically at the solar simulator setup, respectively through UV/Vis absorption spectroscopy, photoluminescence (PL), scanning electron microsco-py (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). In a classical approach, which has been optimized within our Surface Science group, a two-step spin coating and chemical bath deposition method for producing the perovskite material methylammonium lead iodide (MAPI) was used in this work to manufacture Glass/FTO/c-TiO2/m-TiO2/MAPI/spiro-MeOTAD/Au solar cells, having a maximum power conversion efficiency (PCE) of 15,6 %, with a solar cell dimension of 32,5 mm2 and a mini-module substrate dimension of 4 cm2. In a next approach, a one-step spin coating and antisolvent method was used according to literature1 to deposit a thin film of a triple cation, double anion lead perovskite: (CsaMAbFAc)1PbIxBr3-x. This approach is used to compare the performance of solar cells made using our lab methods and the production of our own stack of materials Glass/FTO/c-TiO2/m-TiO2/(CsaMAbFAc)1PbIxBr3-x/spiro-MeOTAD/Au with those in literature. While according to literature1 the published per-ovskite recipe reached a maximum PCE of over 20% in the authors’ labs, a maximum efficiency of 18,5 % could be obtained within this work. A further increase in efficiency is discussed with respect to our solar simulator measurement method. Furthermore, a flash evaporation setup has been built and employed in a novel solvent-free approach to produce films of the alterna-tive perovskite material for solar cells, methylammonium tin iodide (MASI), which uses tin (Sn) instead of the widely used lead (Pb). These experiments show that the flash evaporation pro-cess can produce MASI films of a high chemical purity. Additionally, a new chemical vapor deposition (CVD) setup has been built and used to test a variety of precursor combinations for synthesizing methylammonium lead iodide (MAPI), formamidinium lead iodide (FAPI), or hy-drogen lead iodide (HPbI3). For producing MAPI perovskite films, methylamine gas (MA) and home-made hydrogen iodide (HI) gas were successfully used. For these reactions, the mecha-nism has been clarified using XPS and XRD. The best solar cell built using the up-scalable CVD setup shows an efficiency of 12,9 %.

description: Recent experiments on microwave-irradiated high-mobility two-dimensional electron systems revealed a novel photoresistivity peak in the vicinity of the second cyclotron resonance harmonic. Here we report on the nonlinear transport measurements and demonstrate that the peak can be induced by modest dc fields and that its position is not affected even by strong dc fields, in contrast to microwave-induced resistance oscillations that shift to higher magnetic fields. These findings reinforce the notion that the peak cannot be described by existing models and provides important constraints for further theoretical considerations.

description: The present study is an attempt to comprehend and interpret the geomorphological factors that contributed to the landscape formation and evolution of the broader area of Pieria Mtns in Northern Greece. Detailed geomorphological mapping was performed utilizing both automated - GIS oriented and traditional geomorphological techniques. In order to scientifically determine the formation and evolution of present day landscape, topography, geology, tectonics and climatic status were taken into consideration. The broader area of Pieria Mtns is a landscape with heterogeneous geomorphological environments. The geomorphological formation and evolution is the result of primarily active tectonics, and exogenic processes from Lower Miocene until present. The combined methodology of GIS oriented and traditional geomorphological mapping was proved to be scientifically accurate although time consuming. Detailed field work was considered mandatory in order to validate the GIS derivatives, and interpret the genesis of the landforms.

description: The tidal disruption of a star by a supermassive black hole provides us with a rare glimpse of these otherwise dormant beasts. It has long been predicted that the disruption will be accompanied by a thermal `flare', powered by the accretion of bound stellar debris. Several candidate disruptions have been discovered in this manner at optical, UV and X-ray wavelengths. Here we explore the observational consequences if a modest fraction of the accretion power is channeled into an ultra-relativistic outflow. We show that a relativistic jet decelerates due to its interaction with the interstellar medium at sub-parsec distances from the black hole. Synchrotron radiation from electrons accelerated by the reverse shock powers a bright radio-infrared transient that peaks on a timescale ~1 yr after disruption. Emission from the forward shock may be detectable for several years after the peak. Deep radio follow-up observations of tidal disruption candidates at late times can test for the presence of relativistic ejecta. Upcoming radio transient surveys may independently discover tens to hundreds of tidal disruptions per year, complimenting searches at other wavelengths. Non-thermal emission from tidal disruption probes the physics of jet formation under relatively clean conditions, in which the flow parameters are independently constrained.

description: Because of its size and geographical position, the Cherbourg roadstead appears as a favourable site for Marine Renewable Energy (MRE) industry. As a result, Cherbourg harbour has undergone profound changes (2015 and 2016) due to the installation of industrial infrastructures to service the needs of expanding MRE further offshore. However, little is known about the morpho-sedimentary distribution and associated dynamics of seabed sediments before and after harbour transformations. This study focuses on sedimentary dynamics using detailed morphological and sedimentological analyses based on data acquired before changes (2012). The main map includes a unique bathymetric map (1:35,000) and sedimentary maps showing the percentage of the characteristic grain size fractions of 184 seabed samples. Despite the high tidal conditions, the roadstead construction had a significant impact on the sedimentary facies and distribution. This study provides a basis for future investigations on geomorphological evolution linked to the impact of anthropogenic development.
Social-emotional functioning in early childhood : investigating developmental patterns in childhood mental health and well-being
Creators: name: Thomson, Kimberly Catherine
Publisher: name: University of British Columbia
Year: 2018

description: Early childhood is a critical developmental period when children form social and emotional sensitivities that will support or undermine their mental health throughout their lives. It is estimated that over half of lifetime mental health problems develop before the age of fourteen, and yet early identification and intervention efforts are often hindered by limited recognition of early mental health indicators and a general absence of population-level monitoring systems. This dissertation addresses these gaps, applying a novel approach (person-centered analysis) to identify latent profiles of social-emotional functioning within population cohorts of children entering Kindergarten in British Columbia from 2001 to 2012. Early childhood social-emotional functioning was measured using the teacher-rated Early Development Instrument (EDI) population health survey that includes measures of internalizing and externalizing behaviours (readiness to explore, aggression, hyperactivity) as well as social competence. Latent profile analysis was used to identify distinguishable profiles of early childhood social-emotional functioning at a population-level. Unique profiles of social-emotional functioning were identified consistently across the three analyses included in this dissertation, with over 55% of children demonstrating overall high social-emotional functioning, over 40% of children demonstrating relative vulnerabilities in internalizing and externalizing behaviours, and approximately 3% of children experiencing multiple comorbid vulnerabilities on nearly all measures. Chapter 2 identifies social gradients in the severity of early childhood social-emotional vulnerabilities, with boys and lower income children over-represented in lower functioning social-emotional profiles. Chapter 3 examines children’s likelihood of depression, anxiety, conduct disorder, attention deficit hyperactivity disorder, and multiple conditions, and finds that the profile group to which children belong in Kindergarten is predictive of their experience of mental health conditions up to ten years later. Chapter 4 demonstrates that children’s Kindergarten social-emotional profile group is also predictive of their self-reported well-being in middle childhood, with evidence that supportive relationships with adults and peers partially mediates these associations. These studies inform our understanding of patterns of early childhood social-emotional functioning by identifying social conditions and behaviour patterns predictive of children’s future mental health outcomes that can be targeted earlier in the life course to help mitigate mental health problems and promote well-being.
A phenomenological theory of nonphotochemical laser induced nucleation

description: Our analysis of the experimental data related to nonphotochemical laser induced nucleation in solutions leads to the inevitable conclusion that the phase transformation is initiated by particles that are metallic in nature. This conclusion appears paradoxical because the final products are dielectric crystals. We show that the experimental results are well accounted for by the theory of electric field induced nucleation of metallic particles that are elongated in the direction of the field. However, new physical and chemical insights are required to understand the structure of the metallic precursor particles and the kinetics of subsequent dielectric crystallization.

description: Most of the studies on optimal transport are done for steady state regime conditions. Yet, there exists numerous examples in living systems where supply tree networks have to deliver products in a limited time due to the pulsatile character of the flow. This is the case for mammals respiration for which air has to reach the gas exchange units before the start of expiration. We report here that introducing a systematic branching asymmetry allows to reduce the average delivery time of the products. It simultaneously increases its robustness against the unevitable variability of sizes related to morphogenesis. We then apply this approach to the human tracheobronchial tree. We show that in this case all extremities are supplied with fresh air, provided that the asymmetry is smaller than a critical threshold which happens to fit with the asymmetry measured in the human lung. This could indicate that the structure is adjusted at the maximum asymmetry level that allows to feed all terminal units with fresh air.

description: In this article we present a detailed litho-structural map of the Oltrepo Pavese, a sector of the Northern Apennines, Southern Lombardy, Italy. Lithology and geological structures are an important basis for different disciplines of Earth Sciences. In particular, for the assessment of earth surface processes such as soil erosion, mass movements, flooding, etc. The Oltrepo Pavese is characterised by a complex geology and related tectonic settings. In this study, we conducted a comprehensive lithological mapping approach considering existing geological maps, and detailed field surveys. The lithotypes have been subdivided into 11 classes based on the dominant outcropping lithologies. Integrating bibliographic data and a detailed Digital Terrain Analysis of a high-resolution DTM (5 m) we detected faults, folds and tectonic lineaments in the study area. The final result is represented by a litho-structural map of the Oltrepo Pavese-area, consisting in two shape files elaborated in an open source GIS environment.
Seismic strengthening of unreinforced masonry walls using sprayable Ecofriendly Ductile Cementitious Composite (EDCC)
Creators: name: Soleimani-Dashtaki, Salman
Publisher: name: University of British Columbia
Year: 2018

description: Due to their good sound and thermal insulation properties, unreinforced masonry (URM) walls are widely used in partitioning many of the commercial and residential buildings worldwide, either as in-fill or stand-alone. URM is considered one of the most common types of partition wall systems in many of the mid-age, low-rise to mid-rise, school and hospital buildings in North America. URM is still a very common and major building material, in many of the developing countries, being used in many residential and commercial buildings. URM partition walls are known to have very low drift capacity in seismic events and the failure mechanisms are known to be mostly brittle and of catastrophic nature, during earthquake ground motion. Compared to other partitioning systems, URM walls tend to perform poorly during earthquake events, leaving many injuries, casualties, and fatalities behind. This dissertation elaborates on development of a novel, effective, and practical methodology for a robust out-of-plane seismic strengthening technique toward seismically upgrading URM partition walls, using a thin plaster layer of sprayable Ecofriendly Ductile Cementitious Composite (EDCC). The EDCC layer is devoted to secure such walls, which exist in most parts of the world; specially, in developing countries, where world’s most population density is concentrated. In many of these countries, retrofit is the only option, since building replacement is not practical nor an economically feasible solution. The EDCC material can be applied in three different methods: hand troweled, hopper sprayed, or pump sprayed. The thickness of the layer can vary between 10mm to 20mm, depending on the design variables. Full-scale URM walls are built, strengthened, and tested on a shake table, using the strongest real historical earthquake records. The EDCC layer is providing nearly full out-of-plane detention for the wall’s building blocks, as well as minor but uniform shear capacity enhancements for the in-plane action; therefore, holding the masonry units together from falling apart and being thrown during an earthquake generated ground motion. The newly developed high performance material is sprayable, ductile, and resilient, while being affordable, and easy to apply, with much less carbon footprint compared to other similar repair materials.

description: In certain approaches to quantum computing the operations between qubits are non-deterministic and likely to fail. For example, a distributed quantum processor would achieve scalability by networking together many small components; operations between components should assumed to be failure prone. In the logical limit of this architecture each component contains only one qubit. Here we derive thresholds for fault tolerant quantum computation under such extreme paradigms. We find that computation is supported for remarkably high failure rates (exceeding 90%) providing that failures are heralded, meanwhile the rate of unknown errors should not exceed 2 in 10^4 operations.

description: Tafí valley is an elongated tectonic basin of about 450 km2 located in NW Argentina in a mountainous frame of metamorphic and granitic Precambrian-Paleozoic rocks belonging to Sierras Pampeanas. This study presents the first detailed geomorphological map of the area. The most representative landforms date to the Lateglacial-Holocene, with four differentiating aggradative units separated by incision phases. Among these phases, it is possible to identify the units H1 (Lateglacial-Early and Middle Holocene) and H2 (Upper Holocene until ca. 600 cal BP). These units are composed of slopes, fluvial terraces, and alluvial fans, forming a coupled system. In some areas, this system is complemented with fluvioglacial and glacial landforms. More recent units (H3 and H4), together with active processes, contribute to the great variety of morphologies represented in the area.
Using Kuiper Belt Binaries to Constrain Neptune's Migration History

description: Approximately 10-20% of all Kuiper belt objects (KBOs) occupy mean-motion resonances with Neptune. This dynamical configuration likely resulted from resonance capture as Neptune migrated outward during the late stages of planet formation. The details of Neptune's planetesimal-driven migration, including its radial extent and the concurrent eccentricity evolution of the planet, are the subject of considerable debate. Two qualitatively different proposals for resonance capture have been proposed--migration-induced capture driven by smooth outward evolution of Neptune's orbit and chaotic capture driven by damping of the planet's eccentricity near its current semi-major axis. We demonstrate that the distribution of comparable-mass, wide-separation binaries occupying resonant orbits can differentiate between these two scenarios. If migration-induced capture occurred, this fraction records information about the formation locations of different populations of KBOs. Chaotic capture, in contrast, randomizes the orbits of bodies as they are placed in resonance. In particular, migration-induced capture produces the following signatures. The 2:1 resonance should contain a dynamically cold component, with inclinations less than 5-10 degrees, having a binary fraction comparable to that among cold classical KBOs. If the 3:2 resonance also hosts a cold component, its binary fraction should be 20-30% lower than in the cold classical belt. Among cold 2:1 (and if present 3:2) KBOs, objects with eccentricities e < 0.2 should have a binary fraction ~20% larger than those with e > 0.2. Searches for cold components in the binary fractions of resonant KBOs are currently practical. The additional migration-generated trends described here may be distinguished with objects discovered by LSST. (Abstract abridged.)

description: We report the observation of a remarkably strong microwave photoresistivity effect in a high-mobility two-dimensional electron system subject to a weak magnetic field and low temperature. The effect manifests itself as a giant microwave-induced resistivity peak which, in contrast to microwave-induced resistance oscillations, appears only near the second harmonic of the cyclotron resonance and only at sufficiently high microwave frequencies. Appearing in the regime linear in microwave intensity, the peak can be more than an order of magnitude stronger than the microwave-induced resistance oscillations and cannot be explained by existing theories.

description: We study Andreev reflection in a ballistic one- dimensional channel coupled in parallel to a superconductor via a tunnel barrier of finite length {\it L}. The dependence of the low-energy Andreev reflection probability {\it R$_{A}$} on {\it L} reveals the existence of a characteristic length scale {\it $\xi$;$_{N}$} beyond which {\it R$_{A}$(L)} is enhanced up to unity despite the low interfacial transparency. The Andreev reflection enhancement is due to the strong mixing of particle and hole states that builds up in contacts exceeding the coherence length {\it $\xi$;$_{N}$}, leading to a small energy gap (minigap) in the density of states of the normal system. The role of the geometry of such hybrid contacts is discussed in the context of the experimental observation of zero-bias Andreev anomalies in the resistance of extended carbon nanotube/superconductor junctions in field effect transistor setups.

The end result was 100,000 words, wrapped in a nice cover, so why did it take so long? This was my first book, and those five years were an apprenticeship where I learnt how to give characters goals, how to describe fictional places, how to build tension, and the importance of developing a baddie. I'd hoped to celebrate my graduation from apprentice to author with a book launch party, but this virus came along, so people in IT Services didn't get their invite. Shame, but I'm working on a sequel, and hopefully there'll be a party.

description: VisIVO is an integrated suite of tools and services specifically designed for the Virtual Observatory. This suite constitutes a software framework for effective visual discovery in currently available (and next-generation) very large-scale astrophysical datasets. VisIVO consists of VisiVO Desktop - a stand alone application for interactive visualization on standard PCs, VisIVO Server - a grid-enabled platform for high performance visualization and VisIVO Web - a custom designed web portal supporting services based on the VisIVO Server functionality. The main characteristic of VisIVO is support for high-performance, multidimensional visualization of very large-scale astrophysical datasets. Users can obtain meaningful visualizations rapidly while preserving full and intuitive control of the relevant visualization parameters. This paper focuses on newly developed integrated tools in VisIVO Server allowing intuitive visual discovery with 3D views being created from data tables. VisIVO Server can be installed easily on any web server with a database repository. We discuss briefly aspects of our implementation of VisiVO Server on a computational grid and also outline the functionality of the services offered by VisIVO Web. Finally we conclude with a summary of our work and pointers to future developments.

description: The discovery of dark energy by the first generation of high-redshift supernova surveys has generated enormous interest beyond cosmology and has dramatic implications for fundamental physics. Distance measurements using supernova explosions are the most direct probes of the expansion history of the Universe, making them extremely useful tools to study the cosmic fabric and the properties of gravity at the largest scales. The past decade has seen the confirmation of the original results. Type Ia supernovae are among the leading techniques to obtain high-precision measurements of the dark energy equation of state parameter, and in the near future, its time dependence. The success of these efforts depends on our ability to understand a large number of effects, mostly of astrophysical nature, influencing the observed flux at Earth. The frontier now lies in understanding if the observed phenomenon is due to vacuum energy, albeit its unnatural density, or some exotic new physics. Future surveys will address the systematic effects with improved calibration procedures and provide thousands of supernovae for detailed studies.

Soldiers of a Different Cloth: Notre Dame Chaplains in World War II

Publisher: name: University of Notre Dame
Year: 2023

description: \u000aIn _Soldiers of a Different Cloth_, New York Times best-selling author and military historian John Wukovits tells the inspiring story of thirty-five chaplains and missionaries who, while garnering little acclaim, performed extraordinary feats of courage and persistence during World War II. Ranging in age from twenty-two to fifty-three, these University of Notre Dame priests and nuns were counselor, friend, parent, and older sibling to the young soldiers they served. These chaplains experienced the horrors of the Death March in the Philippines and the filthy holds of the infamous Hell Ships. They dangled from a parachute while descending toward German fire at Normandy and shivered in Belgium's frigid snows during the Battle of the Bulge. They languished in German and Japanese prison camps, and stood speechless at Dachau.\u000a \u000aBased on a vast collection of letters, papers, records, and photographs in the archives of the University of Notre Dame, as well as other contemporary sources, Wukovits brings to life these nearly forgotten heroes who served wherever duty sent them and wherever the war dictated. Wukovits intertwines their stories on the battlefronts with their memories of Notre Dame. In their letters to their superior in South Bend, Indiana, they often asked about campus, the Grotto, and the football team. Their love for Notre Dame helped buttress them during their wartime tribulations, and their return to campus was akin to a warm homecoming. _Soldiers of a Different Cloth_ will fascinate and engage all readers interested in the history of World War II and alumni, friends, and fans of the Fighting Irish.\u000a

description: The measurement of nuclear Generalized Parton Distributions (GPDs) represents a valuable tool to understand the structure of bound nucleons and the phenomenology of hard scattering off nuclei. By using a realistic, non-relativistic microscopic approach for the evaluation of GPDs of 3He, it will be shown that conventional nuclear effects, such as isospin and binding ones, or the uncertainty related to the use of a given nucleon-nucleon potential, are bigger than in the forward case so that, if great attention is not paid, conventional nuclear effects can be easily mistaken for exotic ones. It is stressed that 3He, for which the best realistic calculations are possible, represents a unique target to discriminate between conventional and exotic effects. The complementary information which could be obtained by using a 3H target, the possible extraction of the neutron information, as well as the relevance of a relativistic treatment, will be also addressed.

description: Depending on its chemical and mineralogical composition, the serpentinite represents a peculiar rocky material, which plays a significant role in influencing pedogenetic weathering, vegetation ecology, geo-mechanical and tectonic processes, as well as gravitational slope failure. In serpentinite-bearing environments the response to gravitational stress is more effective than in other rock types. In the Monviso meta-ophiolite Complex (Western Alps), a close relation between landsliding and serpentinite rock occurrences is particularly evident. Our geological map (Main Map), at a scale 1:10,000, illustrates the geology and geomorphological features of the Pui-Orgiera giant (2.98 km2) complex landslide, located on the southern slope of the Monviso Massif. This map clearly documents that the characteristics and kinematics of the landslide are closely associated to the anomalous thickening and widening increase of the Baracun Shear Zone, a remnants of an intra-oceanic detachment fault which separates serpentinite and meta-intrusives from metabasalt and metasediments of the Monviso meta-ophiolite Complex.

description: With an increasing focus on bicycling as a mode of urban transportation, there is a pressing need for advanced tools for bicycle travel analysis and modeling. The objective of this thesis is to introduce “Biking schedules” to represent archetypal urban cycling dynamics along with its methods of construction and potential applications. Biking schedules are constructed by appending short trip segments, called microtrips, together. Three different methods of constructing biking schedules with both speed and road grade attributes are developed. As an initial proof-of-concept, the methods are applied and compared using a pre-existing demonstration data set of 55 hours of 1-Hz on-road GPS data from three cyclists. Biking schedules are evaluated based on their ability to represent the speed dynamics, power output, and breathing rates of a calibration data set and then validated for different riders. The impact of using coarser 3, 5, and 10 second GPS logging intervals on the accuracy of the schedules is also evaluated. Results indicate that the best biking schedule construction method depends on the volume and resolution of the calibration data set. Overall, biking schedules can successfully represent most of the assessed characteristics of cycling dynamics in the calibration data set within 5%. As a second step, the biking schedule construction methods are further developed and validated by collecting and applying a large, naturalistic, GPS-based data set of 2314 bicycle trips in Vancouver, Canada. We specifically explored the optimal microtrip definition to be adopted in constructing biking schedules. The choice of the optimal microtrip definition depends on the parameter that biking schedules are originally generated to model. Generally, the 150m microtrips generated the most precise biking schedules. The collected data are also used to compare the travel characteristics and construct biking schedules for regular and electric bikes. Results show that electric bikes travel 7 km/hr and accelerate 0.17 km/hr/sec faster than regular bicycles. Moreover, the total energy used to move electric bikes is almost twice as much as the energy used by regular bikes. These results have implications in designing bike lanes and safety analysis. Potential applications for biking schedules are also discussed.

description: As more and more network-structured data sets are available, the statistical analysis of valued graphs has become common place. Looking for a latent structure is one of the many strategies used to better understand the behavior of a network. Several methods already exist for the binary case. We present a model-based strategy to uncover groups of nodes in valued graphs. This framework can be used for a wide span of parametric random graphs models and allows to include covariates. Variational tools allow us to achieve approximate maximum likelihood estimation of the parameters of these models. We provide a simulation study showing that our estimation method performs well over a broad range of situations. We apply this method to analyze host--parasite interaction networks in forest ecosystems.

description: The Cinque Terre National Park (38 km2) has recently recorded a remarkable increase in tourists involved in outdoor activities such as hiking. However, due to the actual slope degradation issues that affect this outstanding terraced landscape, hiking trails are increasingly threatened by the impact of landslides. This produces severe landslide-related risk scenarios for hikers. In this study, a landslide inventory map (at 1:45000 scale) has been prepared through the revision/update of previous database and the analysis of air-photos and satellite images coupled with field surveys. Furthermore, a quantitative evaluation of the interaction between landslides and hiking trails has been performed by the definition of a Footpath Landslide Index. More than 400 landslides were identified highlighting that these phenomena represent the main source of hazard. The findings of this study reveal that side-hill trails are the most hazardous since hikers can be potentially affected by flow-like or fast-moving landslides.

description: We investigate the halo occupation distribution (HOD) of black holes within a hydrodynamic cosmological simulation that directly follows black hole growth. Similar to the HOD of galaxies/subhalos, we find that the black hole occupation number can be described by the form N_BH proportional to 1+ (M_Host)^alpha where alpha evolves mildly with redshift indicating that a given mass halo (M_Host) at low redshift tends to host fewer BHs than at high redshift (as expected as a result of galaxy and BH mergers). We further divide the occupation number into contributions from black holes residing in central and satellite galaxies within a halo. The distribution of M_BH within halos tends to consist of a single massive BH (distributed about a peak mass strongly correlated with M_Host), and a collection of relatively low-mass secondary BHs, with weaker correlation with M_Host. We also examine the spatial distribution of BHs within their host halos, and find they typically follow a power-law radial distribution (i.e. much more centrally concentrated than the subhalo distribution). Finally, we characterize the host mass for which BH growth is feedback dominated (e.g. star formation quenched). We show that halos with M_Host > 3 * 10^12 M_sun have primary BHs that are feedback dominated by z~3 with lower mass halos becoming increasingly more affected at lower redshift.

description: Abstract: Photosynthesis-related pathways are regarded as a promising avenue for crop improvement. Whilst empirical studies have shown that photosynthetic efficiency is higher in microalgae than in C3 or C4 crops, the underlying reasons remain unclear. Using a tailor-made microfluidics labelling system to supply 13CO2 at steady state, we investigated in vivo labelling kinetics in intermediates of the Calvin Benson cycle and sugar, starch, organic acid and amino acid synthesis pathways, and in protein and lipids, in Chlamydomonas reinhardtii, Chlorella sorokiniana and Chlorella ohadii, which is the fastest growing green alga on record. We estimated flux patterns in these algae and compared them with published and new data from C3 and C4 plants. Our analyses identify distinct flux patterns supporting faster growth in photosynthetic cells, with some of the algae exhibiting faster ribulose 1,5-bisphosphate regeneration and increased fluxes through the lower glycolysis and anaplerotic pathways towards the tricarboxylic acid cycle, amino acid synthesis and lipid synthesis than in higher plants.

description: Abstract: In the standard approach to deriving inflationary predictions, we evolve a vacuum state in time according to the rules of a given model. Since the only observables are the future values of correlators and not their time evolution, this brings about a large degeneracy: a vast number of different models are mapped to the same minute number of observables. Furthermore, due to the lack of time-translation invariance, even tree-level calculations require an increasing number of nested integrals that quickly become intractable. Here we ask how much of the final observables can be “bootstrapped” directly from locality, unitarity and symmetries. To this end, we introduce two new “boostless” bootstrap tools to efficiently compute tree-level cosmological correlators/wavefunctions without any assumption about de Sitter boosts. The first is a Manifestly Local Test (MLT) that any n-point (wave)function of massless scalars or gravitons must satisfy if it is to arise from a manifestly local theory. When combined with a sub-set of the recently proposed Bootstrap Rules, this allows us to compute explicitly all bispectra to all orders in derivatives for a single scalar. Since we don’t invoke soft theorems, this can also be extended to multi-field inflation. The second is a partial energy recursion relation that allows us to compute exchange correlators. Combining a bespoke complex shift of the partial energies with Cauchy’s integral theorem and the Cosmological Optical Theorem, we fix exchange correlators up to a boundary term. The latter can be determined up to contact interactions using unitarity and manifest locality. As an illustration, we use these tools to bootstrap scalar inflationary trispectra due to graviton exchange and inflaton self-interactions.
