Maternal adaptation to parenthood in the second year
Creators: name: Painter, Susan Lee
Publisher: name: University of British Columbia
Year: 2010

description: The long tradition of research on the parent-child relationship has focused mainly upon the child's development. Even in studies of parental attitudes and childrearing practices, and in research on the mother-infant attachment relationship, the ultimate goal has been explanation of child behavior and development. Much of the research on the parent-child relationship has concentrated on the infancy period and has involved detailed descriptions of parent-child interactive behavior. In contrast, this study of maternal adaptation to parenthood focuses on the mother's experiences and behavior in the toddler period. Three issues were addressed: First, a description of the dimensions of maternal adaptation in the toddler period was sought. Second, the role of maternal confidence and self-esteem, previously shown to be important in maternal adaptation in the infancy period, was explored for maternal adaptation in the toddler period. Third, the mother's own perceptions of her relationships and experiences were compared with behavioral observations made in the laboratory. Sixty mothers of toddlers provided self-report data on their relationships with their child and husband, their emotional state, their activities outside the home, their concerns about conflicts experienced between their parental and other roles, and current childcare arrangements. Mother-toddler interaction was observed in a structured laboratory situation designed to assess the mother's ability to assist her child with a number of tasks. Factor analyses of the self-report data revealed eleven factors comprising five dimensions of maternal adaptation: mother's perception of the maternal role; the marital relationship and experiences of conflicting role demands; the mother's percpetion of support received from her husband and enjoyment shared with her toddler; management of the instrumental or child-care aspects of the parental role; and the mother's overall outlook on life, including her confidence and self-esteem both within and outisde the parental role. Laboratory-based observations of maternal behavior were found to be unrelated to self-report data. It was concluded that the problems posed by parenthood for mothers of toddlers are not limited to the needs or behavior of the child, or to the mother-child relationship itself, but encompass the need to integrate the wide range of roles and experiences that make up the mother's life.

description: Two families of exact simple solutions of Einstein field equations for inhomogeneous stiff cosmologies are presented. The method to obtain the solutions is based on the introduction of auxiliary functions in order to cast the Einstein equations in such a way that can be explicitly integrated. Now, despite of the equations are mathematically equivalent to the equations obtained when the source of matter is a scalar field, is worth to mention that the source that we consider is not a scalar field but a perfect fluid with the stiff equation of state. The obtained solutions are expressed in terms of simple functions of the used coordinates and two families of particular solutions are considered. The geometrical and kinematical properties of the solutions are then analyzed and the parameters are restricted in order to have a physically acceptable behavior. The two particular solutions are of the Petrov type I, the first one being regular everywhere whereas the second one presents a big-bang singularity. Now, for a particular value of one of the parameters, the second particular solution is a vacuum solution of the Bianchi I type that reduces to the Kasner solution.

description: Bacterial growth is classically assessed by measuring the increases in optical density of pure cultures in shaken liquid media. Measuring growth using optical density has severe limitations when studying multistrain interactions, as it is not possible to measure the growth of individual strains within mixed cultures. Here, we demonstrated that constitutively expressed fluorescent proteins can be used to track the growth of individual strains in different liquid media. Fluorescence measurements were highly correlated with optical density measurements and cell counts. This allowed us to assess bacterial growth not only in pure cultures but also in mixed bacterial cultures and determine the impact of a competitor on a focal strain, thereby assessing relative fitness. Furthermore, we were able to track the growth of two different strains simultaneously by using fluorescent proteins with differential excitation and emission wavelengths. Bacterial densities measured by fluorescence yielded more consistent data between technical replicates than optical density measurements. Our setup employs fluorescence microplate readers that allow high throughput and replication. IMPORTANCE We expand on an important limitation of the concept of measuring bacterial growth, which is classically limited to one strain at a time. By adopting our approach, it is possible to measure the growth of several bacterial strains simultaneously with high temporal resolution and in a high-throughput manner. This is important to investigate bacterial interactions, such as competition and facilitation.

description: Die Identifikation von Strategien zur Steigerung der Nachhaltigkeit von Produkten stellt produzierende Unternehmen vor große Herausforderungen. Die Voraussetzung zur Optimierung von Produkten ist die zuverlässige Ermittlung von ökologischen Kennzahlen wie dem CO₂-Fußabdruck. Die Berechnung des CO₂-Fußabdrucks ist allerdings an Rahmenbedingungen und Unsicherheiten geknüpft, da oftmals Sekundärdaten oder Schätzwerte in der Bilanzierung verwendet werden. Diese Unsicherheiten tauchen im alleinstehenden Endwert nicht auf und werden in der Nachhaltigkeitsbetrachtung üblicherweise vernachlässigt.
Die vorliegende Dissertation präsentiert ein Konzept zur Berechnung des CO₂-Fußabdrucks von Produkten mit ergänzendem Qualitätsmanagement und integriert die Kennzahl in den Digitalen Master bzw. Digitalen Zwilling des Produkts. Das Konzept ermöglicht die Berechnung des CO₂-Fußabdrucks in den Phasen der Produktentstehung durch die Nutzung unterschiedlicher Datenquellen. In den Phasen der virtuellen Produktentwicklung wird der Digitale Master verwendet, um Sekundärdaten aus Simulationsdaten, wie beispielsweise Rohmaterial oder Verbrauch einer Fertigungsmaschine, zu berechnen. Ab der Phase der Produktion kann der Digitale Zwilling genutzt werden, um Primärdaten automatisiert abzuleiten. Das Berechnungskonzept des CO₂-Fußabdrucks beinhaltet eine Ermittlung der Unsicherheit und wird durch ein Qualitätsmanagement ergänzt. Das Qualitätsmanagement beruht auf der Vergabe von Qualitätsindikatoren und resultiert in der neu entwickelten Kennzahl der Aussagekraftzahl des CO₂-Fußabdrucks. Begleitet wird die Berechnung des CO₂-Fußabdrucks durch ein Provenienzmodell, welches die Berechnung und deren Ursprung als Graph abbildet. Der Graph bietet eine Optimierungsgrundlage, indem die Hauptverursacher als Anteile an der Gesamtkennzahl direkt einsehbar sind. Weiterhin bildet der Graph die Aktivitäten, deren beteiligte Akteure sowie deren Vernetzung ab und es werden Informationen zur Zusammensetzung der Berechnung, den Autoren und Informationslücken dargestellt.
Das Resultat des CO₂-Fußabdrucks und des Qualitätsmanagements wird nach der Berechnung mit dem Digitalen Master bzw. Digitalen Zwilling verknüpft und wird somit in den Phasen der Produktentstehung als Grundlage einer Optimierung des Produkts zur Steigerung der ökologischen Nachhaltigkeit verstanden. 
Das Konzept dieser Dissertation wird in einem softwaretechnischen Anwendungssystem prototypisch umgesetzt, welches als Assistenzsystem in der Produktentstehung genutzt werden kann.

description: Enthusiasm has emerged for the potential of liquid biopsies to provide easily accessible genetic biomarkers for early diagnosis and mutational cancer characterization. We here systematically investigated the suitability of circulating cell-free DNA (cfDNA) analysis for mutation detection in colorectal cancer (CRC) patients with respect to clinicopathological disease stage. Droplet Digital PCR (ddPCR) was performed to detect common point mutations in the KRAS and BRAF oncogenes in cfDNA from 65 patients and compared to mutations in tumor tissue. Stage of disease was classified according to UICC (Union for International Cancer Control) criteria. In tumor tissue, KRAS or BRAF mutations were present in 35 of 65 cases (44% UICC stage I, 50% stage II, 47% stage III, and 62% stage IV). Although cfDNA was detected in 100% of patients, ddPCR displayed the tumor tissue mutation in only 1 of 6 (17%) stage II patients, whereas 10 of 18 (56%) reported variants were verified in cfDNA samples of the stage IV cohort. No BRAF or KRAS mutation was detected in cfDNA from patients with wild-type tumor tissue. In one case of mutant stage II colon cancer (KRAS-G12C), the G12D variant was detected in cfDNA instead. Further workup revealed that circulating tumor-derived DNA and liver metastases originated from a synchronous KRAS-mutated cancer of the pancreas. Our results demonstrate that ddPCR-based analysis is highly specific and useful for mutation monitoring, but the sensitivity limits its usefulness for early cancer detection.
A Method For Adding Motion-Blur on Arbitrary Objects By using Auto-Segmentation and Color Compensation Techniques

description: When dynamic objects are captured by a camera, motion blur inevitably occurs. Such a blur is sometimes considered as just a noise, however, it sometimes gives an important effect to add dynamism in the scene for photographs or videos. Unlike the similar effects, such as defocus blur, which is now easily controlled even by smartphones, motion blur is still uncontrollable and makes undesired effects on photographs. In this paper, an unified framework to add motion blur on per-object basis is proposed. In the method, multiple frames are captured without motion blur and they are accumulated to create motion blur on target objects. To capture images without motion blur, shutter speed must be short, however, it makes captured images dark, and thus, a sensor gain should be increased to compensate it. Since a sensor gain causes a severe noise on image, we propose a color compensation algorithm based on non-linear filtering technique for solution. Another contribution is that our technique can be used to make HDR images for fast moving objects by using multi-exposure images. In the experiments, effectiveness of the method is confirmed by ablation study using several data sets.

description: New York Times Op-Ed
description: In order to combat the threat of biological weapons, more than $20 billion has been spent on bio-defense research since 2001.This has led to a an increase of research facilities as well as the number of people who have access to the materials. However, the 2001 anthrax mailings were conducted by a top Army bio-defense scientist, Dr Bruce Ivins and the anthrax powder originated from the Army bio-defense research center at Fort Detrick, MD. This suggest that the bio-defense program risks creating the very threat it is meant to fight. Elisa D. Harris recommends that a full public examination of all the governments evidence in the 2001 anthrax mailings should occur in order to determine what went wrong. Then the overall bio-defense research strategy must be re-examined, along with the setting of clear priorities, strengthening safety, and ensuring security and oversight of laboratories working with dangerous agents. Harris suggests that the probability of an attack on the American public is low, but any such attack would be devastating.  Therefore, the US cannot meet the threat safely or effectively with a strategy that puts bio-weapons agents in more and more people’s hands.

description: Societal Impact Statement Across industrial societies, midsize farms are in decline. A future of sustainable agriculture will require more than industrial and cottage farmers. We show that emergent mycorrhizal science is well-suited to support applications for an “agriculture of the middle,” and note two obstacles to the development of more integrated mycorrhizal technologies: an overreliance on commercial inoculants (industrial agriculture) and a tendency to treat soil biology as a black box (cottage agriculture). In this paper, we aim to provoke conversation among policy makers, research funders, and corporate executives on the development of mycorrhizal technologies for an agriculture of the middle. Summary Arbuscular mycorrhizal fungi (AMF) are dealt with in agriculture in a strongly bifurcated way: products and techniques to optimize AMF communities are designed for either large-scale (industrial) or small-scale (cottage) farming operations. We show how research and applications with AMF are bound up in these contrasting visions for what agriculture should be—an industrial system based on economies of scale, or small-scale operations that cater to regional societies, economies, and ecologies. These distinct socially and technologically bound initiatives—which involve research institutions, government policies, corporate investment, activism, and public relations campaigns—we refer to as sociotechnical imaginaries. Drawing from emergent mycorrhizal research, we argue that mycorrhizal technologies are well-suited to an “agriculture of the middle,” a mode of farming that is not strictly scale-based, yet falls somewhere between the industrial and the cottage. Unlike these two extremes, middle agriculture does not have a well-established sociotechnical imaginary. Developing this collective vision poses a challenge: will a middle agriculture that uses AMF fall short of the established goals of industrial and cottage modes of farming? The process of determining appropriate compromises on a wide range of parameters is likely to be contested. However, we believe that calling attention to these extreme visions of agriculture, along with the divergent (if potential) roles of mycorrhizal applications, will jumpstart a productive dialogue among stakeholders, including farmers, policy makers, scientists, and industrialists. Highlighting extremes may also help stimulate ideas about building bridges between seemingly irreconcilable and contradictory approaches.

description: In this paper we explicitly carry out the perturbative renormalization of the $T\bar{T}$-deformed free massive Dirac fermion in two dimensions up to second order in the coupling constant. This is done by computing the two-to-two $S$-matrix using the LSZ reduction formula and canceling out the divergences by introducing counterterms. We demonstrate that the renormalized Lagrangian is unambiguously determined by demanding that it gives the correct $S$-matrix of a $T\bar{T}$-deformed integrable field theory. Remarkably, the renormalized Lagrangian is qualitatively very different from its classical counterpart.

description: We present a low-noise, high modulation-bandwidth design for a laser current driver with excellent long term stability. The driver improves upon the commonly-used Hall-Libbrecht design. The current driver can be operated remotely by way of a micro-processing unit, which controls the current set point digitally. This allows precise repeatability and improved accuracy and stability. It also allows the driver to be placed near the laser for reduced noise and for lower phase lag when using the modulation input. We present the theory of operation for our driver in detail, and give a thorough characterization of its stability, noise, set point accuracy and repeatability, temperature dependence, transient response, and modulation bandwidth.

description: Background: The best strategy to identify patients with suspected acute ischemic stroke and unknown vessel status (large vessel occlusion) for direct transport to a comprehensive stroke center instead of a nearer primary stroke center is unknown. Methods and Results: We used mathematical modeling to estimate the impact of 10 increasingly complex prehospital triage strategy paradigms on the reduction of population-wide stroke-related disability. The model was applied to suspected acute ischemic stroke patients in (1) abstract geographies, and (2) 3 real-world urban and rural geographies in Germany. Transport times were estimated based on stroke center location and road infrastructure; spatial distribution of emergency medical services calls was derived from census data with high spatial granularity. Parameter uncertainty was quantified in sensitivity analyses. The mothership strategy was associated with a statistically significant population-wide gain of 8 to 18 disability-adjusted life years in the 3 real-world geographies and in most simulated abstract geographies (net gain -4 to 66 disability-adjusted life years). Of the more complex paradigms, transportation of patients with clinically suspected large vessel occlusion based on a dichotomous large vessel occlusion detection scale to the nearest comprehensive stroke center yielded an additional clinical benefit of up to 12 disability-adjusted life years in some rural but not in urban geographies. Triage strategy paradigms based on probabilistic conditional modeling added an additional benefit of 0 to 4 disability-adjusted life years over less complex strategies if based on variable cutoff scores. Conclusions: Variable stroke severity cutoff scores were associated with the highest reduction in stroke-related disability. The mothership strategy yielded better clinical outcome than the drip-'n'-ship strategy in most geographies.

description: The present work focuses on the modeling of the thermal system composed of several modules, in which the general model of the system is built, which includes all its components in operation. The environment collected data in real time of the growth and decrease (temperature) curve of a soldering iron tool, under aspects of PWM variation - Pulse Width Modulation - of the signal. It is used as a representative model of device in industrial welding, in which it has similarities in key aspects of behavior. Through analysis and software assistance, the function of transferring the general plan was obtained, which showed an acceptable level of correspondence (86.04%) in non-linear systems. Based on the model discovered, a PI-type controller - Proportional Integral - was designed, paying attention to the need for a low-level overshoot signal (6.08%) in order to obtain a response to the rapid stabilization step, rare in thermal systems. The PI was developed in order to generate an output in DC format (Duty Cycle format), since the raw data of the system were collected by varying this indicator at regular intervals of time. After the tests carried out in simulation, results were obtained that confirm that the developed control system is applicable and responds appropriately, being able to be optimized for applications.

description: Motivated by the recent experiments by the Westervelt group using a mobile tip to probe the electronic state of quantum dots formed on a segmented nanowire, we study the shifts in Coulomb blockade peak positions as a function of the spatial variation of the tip potential, which can be termed "Coulomb blockade microscopy". We show that if the tip can be brought sufficiently close to the nanowire, one can distinguish a high density electronic liquid state from a Wigner crystal state by microscopy with a weak tip potential. In the opposite limit of a strongly negative tip potential, the potential depletes the electronic density under it and divides the quantum wire into two partitions. There the tip can push individual electrons from one partition to the other, and the Coulomb blockade micrograph can clearly track such transitions. We show that this phenomenon can be used to qualitatively estimate the relative importance of the electron interaction compared to one particle potential and kinetic energies. Finally, we propose that a weak tip Coulomb blockade micrograph focusing on the transition between electron number N=0 and N=1 states may be used to experimentally map the one-particle potential landscape produced by impurities and inhomogeneities.

description: Radio observations of gas in the Milky Way and Local Group are vital for understanding how galaxies function as systems. The unique sensitivity of Arecibo's 305m dish, coupled with the 7-beam Arecibo L-Band Feed Array (ALFA), provides an unparalleled tool for investigating the full range of interstellar phenomena traced by the HI 21cm line. The GALFA (Galactic ALFA) HI Survey is mapping the entire Arecibo sky over a velocity range of -700 to +700 km/s with 0.2 km/s velocity channels and an angular resolution of 3.4 arcminutes. We present highlights from the TOGS (Turn on GALFA Survey) portion of GALFA-HI, which is covering thousands of square degrees in commensal drift scan observations with the ALFALFA and AGES extragalactic ALFA surveys. This work is supported in part by the National Astronomy and Ionosphere Center, operated by Cornell University under cooperative agreement with the National Science Foundation.

description: We prove the existence of minimizers for Hartree-Fock-Bogoliubov (HFB) energy functionals with attractive two-body interactions given by Newtonian gravity. This class of HFB functionals serves as model problem for self-gravitating relativistic Fermi systems, which are found in neutron stars and white dwarfs. Furthermore, we derive some fundamental properties of HFB minimizers such as a decay estimate for the minimizing density. A decisive feature of the HFB model in gravitational physics is its failure of weak lower semicontinuity. This fact essentially complicates the analysis compared to the well-studied Hartree-Fock theories in atomic physics.

Evolution of colour signals in lizards

description: Animals use a spectacular diversity of signals and the study of signals is central to understanding a range of biological processes including how animals interact socially, and how new species arise. According to animal communication theory, signal design evolves in response to two main selective forces acting on the tactical transmission of strategic information. Strategic design refers to any element associated with information content (i.e. signal reliability), while tactical design has to do with the efficacy with which signals are transmitted, perceived, and processed by receivers in the environment (i.e. signal efficacy). Understanding how selection on the strategic and tactical components interact to shape signal design is crucial to unravelling the true complexity of animal communication. Colour signals constitute a major and functionally diverse class of signals. It is only recently that the signalling role of structurally produced colours, such as ultraviolet (UV), has been documented. UV colours, invisible to the human eye, have long gone unnoticed by scientists, and yet, their potential to remain hidden from predators lacking UV vision makes them particularly interesting. During my PhD, I used lizards as a model to study the adaptive co- variation across and between UV colour features in relation to environmental factors and individual traits. More specifically, my objectives were 1.) to improve the general approach used to objectively measure small colour patches, 2.) to study how and to what extent habitat conditions can generate substantial variation in the design of UV signals at various levels of integration (i.e. intra-population and inter-population), 3.) to explore the information content of UV signals in detail; that is, to investigate how design components relate to each other and to individual quality traits, and 4.) to explore the possible roles UV colours may play in lizards, for example as deimatic (warning) displays. To answer these questions, the European common wall lizard (Podarcis muralis) is an ideal model because males display sexually selected UV-blue signals on their flanks. First and foremost, after refining the methodology for reflectance spectrophotometry, I provide strong evidence that habitat conditions drive an adaptive response in the design of UV signals, whereby several signal design components respond to different selective pressures both within and between populations. In addition, I demonstrate that UV signals are complex multicomponent signals advertising male quality traits. Finally, I provide an example of UV patterns that potentially function as a deimatic display in the Australian northern blue-tongue skink (Tiliqua scincoides intermedia). This PhD thesis thus provides important insights rooted in animal communication theory and pave the way for future research foci.

description: Recent studies of dynamic properties in complex systems point out the profound impact of hidden geometry features known as simplicial complexes, which enable geometrically conditioned many-body interactions. Studies of collective behaviours on the controlled-structure complexes can reveal the subtle interplay of geometry and dynamics. Here, we investigate the phase synchronisation dynamics under the competing interactions embedded on 1-simplex (edges) and 2-simplex (triangles) faces of a homogeneous 4-dimensional simplicial complex. Its underlying network is a 1-hyperbolic graph with the assortative correlations among the node's degrees and the spectral dimension that exceeds $d_s=4$. We determine the time-averaged system's order parameter to characterise the synchronisation level. In the absence of higher interactions, the complete synchrony is continuously reached with the increasing positive pairwise interactions ($K_1>0$), and a partial synchronisation for the negative couplings ($K_1<0$) with no apparent hysteresis. Similar behaviour occurs in the degree-preserved randomised network. In contrast, the synchronisation is absent for the negative pairwise coupling in the entirely random graph and simple scale-free networks. Increasing the strength $K_2\neq 0$ of the triangle-based interactions gradually hinders the synchronisation promoted by pairwise couplings, and the non-symmetric hysteresis loop opens with an abrupt desynchronisation transition towards the $K_1<0$ branch. However, for substantial triangle-based interactions, the frustration effects prevail, preventing the complete synchronisation, and the abrupt transition disappears. These findings shed new light on the mechanisms by which the high-dimensional simplicial complexes in natural systems, such as human connectomes, can modulate their native synchronisation processes.

description: Genetic differences among human groups can be ascribed both to the broad-scale extents of pre-historical and historical migrations and to the fine-scale impacts of socio-cultural and geographic heterogeneity. In this thesis, the genetic information provided by uniparental markers were exploited to address different aspects of the Italian population history, by combining macro- and micro-geographic investigations at different spatial and temporal scales.
To firstly assess the overall Italian variability, Y-chromosome and mtDNA markers were deeply typed in ~900 individuals from continental Italy, Sicily and Sardinia. Sex-biased patterns and contrasting demographic histories were observed for males and females. Differential European and Mediterranean contributions were invoked to explain the paternal genetic sub-structure observed in peninsular Italy, compared to the homogeneous maternal genetic landscape. If Neolithic showed to be one principal determinant of the detected paternal structure, local insights into specific Italian regional contexts highlighted the importance of Post-Neolithic contributions. Among them, migrations from the Balkans (particularly Greece) during late Metal Ages, played a relevant role in the cultural and genetic transitions occurred in Sicily and Southern Italy.
On a finer geographic and temporal perspective, the more recent layers of Italian genetic history and some aspects of the gene-culture interaction were assessed by exploring the genetic variability within two “marginal populations”: Arbereshe of Southern Italy and Partecipanza in Northern Italy. The Arbereshe are Albanian-speaking communities settled in Sicily and Calabria since the end of Middle Ages. Despite sharing common genetic and cultural backgrounds, these groups revealed diverging micro-evolutionary histories, implying different founding events and different patterns of cultural isolation and local admixture. Partecipanza is an idiosyncratic institution of Medieval origin aimed at sharing and devolving collective lands. This case-study exemplified that socio-economic stratification within the same population may induce sex-biased genetic structuring and the maintenance of otherwise hidden historical genetic traces.

description: We show effects of granular structure of the initial conditions (IC) of hydrodynamic description of high-energy nucleus-nucleus collisions on some observables, especially on the elliptic-flow parameter v2. Such a structure enhances production of isotropically distributed high-pT particles, making v2 smaller there. Also, it reduces v2 in the forward and backward regions where the global matter density is smaller, so where such effects become more efficacious.

description: Superconductors with non-trivial band topology are emerging as one of the best avenues to study quantum anomalies and experimental realization of Majorana Fermions. This article reports the successful crystal growth of superconducting SnAs, which can have topologically non-trivial states, as evidenced in DFT (Density Functional Theory) calculations, Z2 invariants, and topologically surface state. Here, we followed a two-step method to grow SnAs crystal. The powder XRD (X-ray Diffractometry) pattern of synthesized crystal ensures that the crystal is grown in a single phase with a NaCl type cubic structure and the EDAX (Energy Dispersive X-ray Analysis) endorses the stoichiometry of the as-grown sample. The DFT calculations performed with and without the inclusion of spin-orbit coupling (SOC) show band inversion at various K symmetry points near the Fermi level. The recorded Raman spectra show two different modes, which are assigned as A1 and ETO vibrations. The ZFC (Zero-Field Cooled) & FC (Field Cooled), as well as the isothermal M-H (Magnetization vs. field) measurements, are also performed for the topological non-trivial SnAs superconductor, which eventually confirms the weak type-II superconductivity at 4K. Various other superconductivity parameters viz. kappa parameter, coherence length, and penetration depth are also calculated to probe the as-grown sample's characteristics.

description: We present a synthesis of fast radio burst (FRB) morphology (the change in flux as a function of time and frequency) as detected in the 400-800 MHz octave by the FRB project on the Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB), using events from the first CHIME/FRB catalog. The catalog consists of 61 bursts from 18 repeating sources, plus 474 one-off FRBs, detected between 2018 July 25 and 2019 July 2. We identify four observed archetypes of burst morphology ("simple broadband," "simple narrowband," "temporally complex" and "downward drifting") and describe relevant instrumental biases that are essential for interpreting the observed morphologies. Using the catalog properties of the FRBs, we confirm that bursts from repeating sources, on average, have larger widths and we show, for the first time, that bursts from repeating sources, on average, are narrower in bandwidth. This difference could be due to a beaming or propagation effects, or it could be intrinsic to the populations. We discuss potential implications of these morphological differences for using FRBs as astrophysical tools.
