A NOVEL MICRO-RNA FAMILY AS MOLECULAR DETERMINANT OF MAMMARY STEM CELLS
Creators: name: TORDONATO, CHIARA
Publisher: name: Universit� degli Studi di Milano
Year: 2015

description: A novel microRNA family as molecular determinant in mammary stem cells MicroRNAs (miRNAs) are an evolutionarily conserved class of small (18-22 nucleotides) noncoding RNAs involved in the regulation of a variety of cellular and developmental processes. MiRNAs have recently emerged as key regulators of transcriptional programs that control self-renewal and the cell-fate of stem cells (SCs). In the breast compartment, forced expression of some miRNAs (e.g. miR-200, let-7 and miR-93) was shown to inhibit normal and/or cancer SCs by silencing self-renewal determinants. In fact, these miRNAs are poorly or not expressed in the SC compartment, and their stem-inhibiting function is mainly achieved through the induction of differentiation. The aim of this project is to identify miRNAs specifically expressed in mammary SCs isolated from normal and cancer samples that could act as markers and/or as regulators of stem cell biology. We will also evaluate their potential as novel therapeutic targets in breast cancer. Using an innovative technique developed in our lab for the isolation of quasi-pure SCs/CSCs, we identified a miRNA family as being highly enriched in the SC compartment, in both primary normal and tumor samples. Endogenous levels of miRNAs of this family can stratify distinct sub-populations with different SC abilities, and in human cancer high miRNA levels correlate with a basal tumor subtype and with an elevated CSC content. Furthermore, depletion of these miRNAs by a synthetic sponge impair self-renewal of SCs/CSCs, as measured by a serial mammosphere propagation assay in human cancer cell lines and in mouse primary epithelial cells. In vivo, miRNA loss reduced the frequency of tumor formation, as well as the mean tumor volume and the frequency of CSCs measured with either an established human basal-like cancer cell line or human patient-derived xenografts (PDXs). To determine the molecular mechanisms underlying the regulation of SCs/CSCs behavior, we employed an unbiased approach assessing the effects of miRNA loss on global gene expression profile, coupled with the prediction of miRNA targets involved in stem cell biology. We identified 91 stem cell genes that are putatively targeted by this miRNA family, belonging to pathways critically involved in the regulation or in the mainteinance of stem cell traits. In conclusion, our results suggest that this SC-specific miRNA family could potentially be used as novel therapeutic targets for breast cancer treatment. This study also provides insights into the mechanisms that sustain CSCs growth in the breast, involving complex molecular circuits of coding as well as noncoding RNAs.

The feasibility of qualitative geospatial methods to explore physical activity in children with developmental disabilities
Creators: name: Tsui, Brianna T.
Publisher: name: University of British Columbia
Year: 2023

description: Background: One in 20 children live with a developmental disability (DD). Children with DD experience significant barriers to physical activity (PA) participation. Greater contextual information regarding their PA behaviours and preferences is needed for effective PA promotion. Purpose: To investigate the feasibility of Geographic Positioning Systems (GPS) and Fitbits with follow up map-based interviews to describe and understand PA behaviours and context in children with DD. Methods: In this explanatory sequential mixed methods study, 15 children with DD were recruited from across British Columbia, Canada, in summer 2022. Participants wore a Fitbit (Charge 4) and a GPS device (QStarz) for 7 days to assess PA (steps/day) and PA location. Intraday Fitbit data was extracted to REDCap via API. Fitbit and GPS data were processed through a custom in-house algorithm to time-align device data, to validate wear time (≥600 min/d), and to identify PA locations and trip mode (walk, car). Geographic Information Systems (GIS ArcMap) was used to create maps from each child’s device data to guide follow up virtual semi-structured interviews with child and parent participants to understand PA contexts and perceptions of daily PA. Statistical analyses were performed in R, with significance set at p<0.05. Interviews were analyzed in NVivo 12 using thematic analysis. Results: Six children had autism, 3 had attention deficit disorder, and 6 had both (age 10±2yrs; 100% boys). Mean steps/d were 8680±4267 across 5±1 days. Compared with older boys (10-12yrs), younger boys (7-9yrs) had significantly higher step counts at home (2795±3271 vs. 1671±1958, p=0.03) and on weekdays (10585±4244 vs.7404±3587, p=0.005). Overall, the most common trip mode was by car (23±51min/d). Children provided their preferences for PA locations using maps. Parents gave context to their child’s PA by expressing how disability type affects PA and identifying key environmental factors in PA locations (e.g., proximity to parks). Conclusion: Utilizing Fitbits and GPS with follow up map-based interviews are feasible to describe PA behaviours and contexts in children with DD. This methodology has the potential to provide novel insight on daily PA in children with DD, which can inform how future interventions can support them to be active.

The coupling is an order of magnitude higher than that seen in the case of (001) trilayers. Magnetoresistance measurements show a first order transition in the data coinciding with the antiferromagnetic regime deduced from the magnetization measurements. I have also measured the anisotropic magnetoresistance (AMR) of these samples revealing an unusually high AMR ($\sim 72000%$). I attribute such a high AMR to the pair breaking effects in these films.

description: The spiral structure of our Milky Way Galaxy is not yet known. HII regions and giant molecular clouds are the most prominent spiral tracers. We collected the spiral tracer data of our Milky Way from the literature, namely, HII regions and giant molecular clouds (GMCs). With weighting factors based on the excitation parameters of HII regions or the masses of GMCs, we fitted the distribution of these tracers with models of two, three, four spiral-arms or polynomial spiral arms. The distances of tracers, if not available from stellar or direct measurements, were estimated kinetically from the standard rotation curve of Brand & Blitz (1993) with $R_0$=8.5 kpc, and $Θ_0$=220 km s$^{-1}$ or the newly fitted rotation curves with $R_0$=8.0 kpc and $Θ_0$=220 km s$^{-1}$ or $R_0$=8.4 kpc and $Θ_0$=254 km s$^{-1}$. We found that the two-arm logarithmic model cannot fit the data in many regions. The three- and the four-arm logarithmic models are able to connect most tracers. However, at least two observed tangential directions cannot be matched by the three- or four-arm model. We composed a polynomial spiral arm model, which can not only fit the tracer distribution but also match observed tangential directions. Using new rotation curves with $R_0$=8.0 kpc and $Θ_0$=220 km s$^{-1}$ and $R_0$=8.4 kpc and $Θ_0$=254 km s$^{-1}$ for the estimation of kinematic distances, we found that the distribution of HII regions and GMCs can fit the models well, although the results do not change significantly compared to the parameters with the standard $R_0$ and $Θ_0$.

description: This exploratory case study examined maternal wellbeing during the preschool years. Research into gender and wellbeing suggests a relationship with relational self-construal, how one defines oneself in relation to close others, which may illuminate the processes by which mothers maintain and enhance their wellbeing. Eight mothers completed three scales to measure relational self-concept, relational self-esteem and life satisfaction and participated in semi-structured interviews. Family were incorporated into the self, more than friends, despite connectedness to friends. The results indicate a need for maternal interventions to focus on intimate relationships, in addition to friendship support.
EMISSIONS ARISING FROM MANURE MANAGEMENT IN DAIRY FARMS: AN EVALUATION USING LIFE CYCLE ASSESSMENT

description: Il crescente consumo di carne e latte a livello mondiale ha causato il cambiamento dei metodi di allevamento da sistemi di tipo estensivo a sistemi di tipo intensivo, e ha fatto emergere una serie di sfide significative nell?ambito del benessere animale, della sostenibilit� ambientale e della sicurezza alimentare. Il contributo degli allevamenti alle emissioni di gas ad effetto serra (GHG) e ammoniaca (NH3) � rilevante e, a ragione, i ruminanti sono accusati di emissioni di metano legate alle fermentazioni enteriche. Perci� l?interesse relativo all?identificazione di possibili strategie di mitigazione da applicare agli allevamenti intensivi � cresciuto negli ultimi anni. I sistemi di gestione possono modificare le caratteristiche fisico-chimiche dei reflui dell?allevamento, influenzando le emissioni di metano, protossido d?azoto ed ammoniaca che da essi hanno origine. Lo scopo di questa tesi � stato quello di valutare le performance ambientali di diversi sistemi di allontanamento delle deiezioni, ampiamente diffusi negli allevamenti della Pianura Padana, con un duplice approccio: (i) misurando le emissioni e (ii) applicando un?Analisi del Ciclo di Vita (LCA) a diverse soluzioni stabulative per stalle di vacche da latte. Come primo passo, � stata condotta una revisione degli studi LCA per comprendere i punti di forza e le debolezze di questo approccio. Difficolt� sono state riscontrate nel paragonare i risultati di diversi studi relativi alla produzione di latte, facendo emergere la necessit� di raggiungere un maggior livello di armonizzazione. In seguito, sono stati misurati i livelli di emissione di GHG ed NH3 da aziende con diversi tipi di gestione delle deiezioni. I dati ottenuti sono stati utilizzati come parametri per compilare l?inventario dell?analisi LCA e fare un paragone tra i potenziali impatti che da essa risultano e quelli che si ottengono utilizzando le equazioni raccomandate per la compilazione dell?inventario. Da questo confronto � emersa l?esigenza di disporre di fattori di emissione che rendano la stima pi� aderente alla variabilit� di condizioni riscontrate nella stalla. Infine, alcuni campioni di refluo provenienti dalle stesse stalle sono stati utilizzati per quantificare la produzione di metano potenzialmente ottenibile. I risultati di questa tesi sottolineano come la scelta della strategia di gestione degli effluenti sia fondamentale nella riduzione dell?impatto ambientale dell?allevamento, poich� in grado di influenzare le emissioni di GHG ed NH3. Inoltre, dal momento che il controllo delle emissioni necessita compromessi tra i diversi gas, spesso � richiesta una combinazione di misure per l?efficace controllo delle emissioni.

description: Single crystals of CeFeAsO, large enough to study the anisotropy of the magnetic properties, were grown by an optimized Sn-flux technique. The high quality of our single crystals is apparent from the highest residual resistivity ratio, RRR = 12, reported among undoped RFeAsO compounds (R=rare earth) as well as sharp anomalies in resistivity, specific heat, C(T), and thermal expansion at the different phase transitions. The magnetic susceptibility chi(T) presents a large easy-plane anisotropy consistent with the lowest crystal electric field doublet having a dominant Gamma_6 character. Curie-Weiss like susceptibilities for magnetic field parallel and perpendicular to the crystallographic c-axis do not reveal an influence of a staggered field on the Ce site induced by magnetic ordering of the Fe. Furthermore, the standard signatures for antiferromagnetic order of Ce at T_N = 3.7 K observed in chi(T) and C(T) are incompatible with a Zeeman splitting Delta = 10 K of the CEF ground state doublet at low temperature due to the Fe-magnetic order as previously proposed. Our results can be reconciled with the earlier observation by assuming a comparatively stronger effect of the Ce-Ce exchange leading to a reduction of this Zeeman splitting below 15 K.

description: We study AAK as well as Padé approximants to functions f, where f is a sum of a Cauchy transform of a complex measure μsupported on a real interval included in (-1,1), whose Radon-Nikodym derivative with respect to the arcsine distribution on its support is Dini-continuous, non-vanishing and with and argument of bounded variation, and of a rational function with no poles on the support of μ. It is shown that the approximants converge to f locally uniformly in the domain of holomorphy of f, intersected with the unit disk in the case of AAK approximants. In the case of Padé approximants we need to assume that the interpolation scheme is "nearly" conjugate-symmetric.

Investigating the impact of a cloud-based BIM tool on design coordination : a case study of the Lions Gate Hospital Acute Care Facility project
Creators: name: Irene, Ruth
Publisher: name: University of British Columbia
Year: 2023

description: Design coordination in the construction industry has improved significantly with the adoption and implementation of Building Information Modelling (BIM) tools. However, the design issue management process is an essential aspect of design coordination and due to the introduction of Cloud-based Building Information Modelling (Cloud-BIM) tools, there is a need to examine the issue management process considering the capabilities of these tools. This research addresses this gap by providing a detailed case study analysis of the Lions Gate Hospital Acute Care Facility (LGH ACF) project, a hospital redevelopment project in North Vancouver. This research investigated the knowledge, processes, experiences, and outcomes of implementing a collaborative Cloud-BIM tool on the LGH ACF project. This was analyzed from the perspectives of technology, organization, and process in the project’s context. A mixed-method approach was adopted for this study. An ethnographic research, surveys, interviews, and document analysis were conducted to better understand the issue management processes and the benefits and challenges of using Cloud-BIM on this project. The project team adopted two issue management processes for design coordination: synchronous and asynchronous issue management processes. To quantify the value of these processes, metrics from the Cloud-BIM issue tracker platform were identified and analyzed, including the number of resolved issues, issue resolution time, resolution time for high-priority issues, and issue engagement. Several qualitative and quantitative analyses revealed that Cloud-BIM significantly impacted the project, especially for issue management. The project team concluded that this platform improved the overall understanding of the project, provided earlier and more accurate visualization of design, and enabled collaboration among multiple disciplines. One potential benefit identified with the synchronous process is that it increases project stakeholder engagement. Additionally, the asynchronous process allowed for the high-priority multi-disciplinary geometric issues to be discussed thoroughly in coordination meetings since it involved resolving various issues without requiring extra coordination meetings. The team was challenged by the change management involved with adopting the Cloud-BIM tool, file upload management, and insufficient training. Future research should explore issue management processes through cross-project analysis and consider various cloud-based platforms.

description: It has been argued that the photometric data and images of the archetypical debris disk around Vega may be in contradiction with the standard, steady-state collisional scenario of the disk evolution. Here we perform physical modeling of the Vega disk "from the sources". We assume that dust is maintained by a "Kuiper belt" of parent planetesimals at ~ 100 AU and employ our collisional and radiative transfer codes to consistently model the size and radial distribution of the disk material and then thermal emission of dust. In doing so, we vary a broad set of parameters, including the stellar properties, the exact location, extension, and dynamical excitation of the planetesimal belt, chemical composition of solids, and the collisional prescription. We are able to reproduce the spectral energy distribution in the entire wavelength range from the near-infrared to millimeter, as well as the mid-IR and sub-millimeter radial brightness profiles of the Vega disk. Thus our results suggest that the Vega disk observations are compatible with a steady-state collisional dust production, and we put important constraints on the disk parameters and physical processes that sustain it. The total disk mass in < 100 km-sized bodies is estimated to be ~ 10 Earth masses. Provided that collisional cascade has been operating over much of the Vega age of ~ 350 Myr, the disk must have lost a few Earth masses of solids during that time. We also demonstrate that using an intermediate luminosity of the star between the pole and the equator, as derived from its fast rotation, is required to reproduce the debris disk observations. Finally, we show that including cratering collisions into the model is mandatory.

description: We consider a string-inspired torsion-dilaton-gravity action in a Randall-Sundrum brane world scenario and show that, in an effective four-dimensional theory on the visible brane, the rank-2 antisymmetric Kalb-Ramond field (source of torsion) is exponentially suppressed. The result is similar to our earlier result in [12], where no dilaton was present in the bulk. This offers an explanation of the apparent invisibility of torsion in our space-time. However, in this case the trilinear couplings ~ Tev^{-1} between dilaton and torsion may lead to new signals in Tev scale experiments, bearing the stamp of extra warped dimensions.

There have been recent investigations examining how cognitive systems such as visual perception vary across individuals from different cultures in a branch of cognitive social psychology. Computational models have been effective in simulating many aspects of cognition, but just how extensive have models been used to inform theory and practice in both cognitive and cultural/social psychology?

description: In this work we discuss a theory for entanglement generation, characterization and detection in fermionic two-particle interferometers at finite temperature. The motivation for our work is provided by the recent experiment by the Heiblum group, Neder et al, Nature 448, 333 (2007), realizing the two particle interferometer proposed by Samuelsson, Sukhorukov, and Buttiker, Phys. Rev. Lett. 92, 026805 (2004). The experiment displayed a clear two-particle Aharonov-Bohm effect, however with an amplitude suppressed due to finite temperature and dephasing. This raised qualitative as well quantitative questions about entanglement production and detection in mesoscopic conductors at finite temperature. As a response to these questions, in our recent work, Samuelsson, Neder, and Buttiker, Phys. Rev. Lett. 102, 106804 (2009) we presented a general theory for finite temperature entanglement in mesoscopic conductors. Applied to the two-particle interferometer we showed that the emitted two-particle state in the experiment was clearly entangled. Moreover, we demonstrated that the entanglement of the reduced two-particle state, reconstructed from measurements of average currents and current cross correlations, constitutes a lower bound to the entanglement of the emitted state. The present work provides an extended and more detailed discussion of these findings.

description: With the development of 5G technology, the miniaturised and highly integrated electronic devices urgently require thermal management materials possessing high thermal conductivity and mechanical properties. In this work, isotactic polypropylene (iPP)/high-density polyethylene (HDPE)-based dielectric composites possessing ideal thermal conductivity and balanced mechanical properties were prepared via Fused Filament Fabrication (FFF). The advanced material properties were achieved by the introduction of hybrid fillers and tailored polymer crystalline structure. The highly oriented h-BN, oriented iPP crystalline and iPP/HDPE epitaxy crystalline were observed. Meanwhile, we studied the effect of the ratio of hybrid fillers on various properties of composites. The thermal conductivity of iPP/HDPE/h-BN/Al2O3 composites reach 1.802 W·m−1·K−1. The impact strength and tensile strength reach 13.23 KJ/m2 and 40 MPa, respectively. In addition, the composites maintain ideal dielectric properties. This work offers a feasible strategy to fabricate dielectric and thermal conductive composites with balanced mechanical properties using semicrystalline polymer through FFF process.

description: Purpose: Weighting can enable valuable support for decision-makers when interpreting life cycle assessment (LCA) results. Distance-to-target (DtT) weighting is based on the distance of policy (desired) targets to current environmental situations, and recent methodological DtT developments are based on a weighting perspective of a single region or country, considering mainly environmental situations in consuming countries or regions. However, as product supply chains are spread over many countries, this study aims at developing additional weighting approaches (producer regions and worst-case regions) and applying them in a theoretical case study on a global scale. Methods: The current study is carried out to understand the influence of and the effect on weighting results of different countries and regions with their specific environmental policy targets. Based on the existing Ecological Scarcity Method (ESM), eco-factors for the three environmental issues climate change, acidification, and water resources were derived for as many countries as possible. The regional eco-factors were applied in a case study for steel and aluminum considering the three different weighting approaches on different regional scales. Results and discussion: The analysis revealed significant differences in the obtained weighting results as well as strengths and limitations in the applicability of the examined perspectives. Acidification was showed to be highly important with between 80 and 92% of the aggregated weighting results among the perspectives where water-scarce countries were not involved. Water-scarce countries had a significant influence (75–95%) when they were part of the examined case study. Conclusions: The developed approaches enable the assessment of global value chains in different producer regions as well as the utilization of the conservative worst-case-regions approach. The approaches can foster future decision-making in LCA contexts while providing country-specific results based on different weighting perspectives in national, regional, and global contexts. However, for a complete implementation of the presented approaches, further data gathering is needed on environmental situations and policy targets in different countries as well as regionalized life cycle data.

description: We prove that any contact metric $(κ,μ)$-space $(M,ξ,ϕ,η,g)$ admits a canonical paracontact metric structure which is compatible with the contact form $η$. We study such canonical paracontact structure, proving that it verifies a nullity condition and induces on the underlying contact manifold $(M,η)$ a sequence of compatible contact and paracontact metric structures verifying nullity conditions. The behavior of that sequence, related to the Boeckx invariant $I_M$ and to the bi-Legendrian structure of $(M,ξ,ϕ,η,g)$, is then studied. Finally we are able to define a canonical Sasakian structure on any contact metric $(κ,μ)$-space whose Boexkx invariant satisfies $|I_M|>1$.

description: The Cosmic Dawn (z~30 to z~10) is the observationally elusive time period in the history of the universe when the first stars ignited and started filling the universe with their light, thereby changing the intergalactic medium (IGM) around them. The UV light from the first stars left an imprint on the 21-cm cosmological signal, which could be detected observationally as a dip in the global 21-cm temperature brightness spectrum. The death of the first stars also effected the 21-cm signal by heating up the gas in the IGM, leading to a rise in the 21-cm temperature brightness temperature. The exact location and shape of the cosmic signal caused by the dip and rise of the 21-cm temperature brightness during this time period is still uncertain, due toinsufficient observational data. Although the EDGES team has reported a potential detection of this cosmological signal, their detection has not be confirmed. Othergroups with vastly different observational systems need to measure the signal for the cosmological community to be convinced of the detection. Our group has developed the High-Z system to measure this cosmological signalfrom the period of the Cosmic Dawn. The High-Z system measures the global average of the 21-cm temperature brightness spectrum but is very different from the systemsused by other 21-cm observational groups. High-Z is the only system to use an unmatched network to measure the 21-cm cosmological signal. In this thesis, I describethe calibration of the High-Z system and the interesting effects that result from the purposeful impedance mismatch of our system. The large impedance mismatch in our system leads to certain effects being magnified, which might not be otherwise noticed in a matched network. The focus of this thesis is primarily on the absolute calibration of the High-Zsystem, along with the development and testing of the different methods for experimentally measuring the noise contribution of the first amplifier in our electronic chain.The complete characterization of the noise properties of the first amplifier, which is the largest contributor of noise in our system, is crucial to the correct calibration of the High-Z system. In addition to calibration, I cover the deployments of the High-Z system in the field on three separate occasions and develop a data analysis pipeline for processing the data from the field.

description: Experiences in childhood are unique to individual children. However, the manner in which children may be treated is affected by societal norms, usually reinforced by legislation. Common law or statute prohibits the 'physical punishment' of children in fourteen countries. Yet, in countries such as Australia, New Zealand, Canada, Britain and the United States, the right to physical integrity accorded to adults is denied to children. In these countries, hitting an adult to cause pain and enforce compliance is unacceptable, and is more likely to be deemed a criminal assault. Hitting children, however, is a securely held, though increasingly questioned, parental right. It is common for children to be 'disciplined' through violent means. Injury, and even death, sometimes results.[…]

description: We report that normal incidence reflection and transmission of circularly polarized electromagnetic waves from and through planar split-ring metamaterials with chiral symmetry breaking depends on the incidence direction and handedness of circular polarization. The effect has a resonant nature and is linked to the lack of mirror-symmetry in the metamaterial pattern leading to a polarization-sensitive excitation of electric and magnetic dipolar responses in the meta-molecules.

Super-homogeneity and inhomogeneities in the large scale matter distribution

description: Super-homogeneity is a property that is supposed to be satisfied by matter fluctuations in all standard theoretical models of structure formation, such as LCDM and its variants. This is a global condition on the correlation properties of the matter density field, which can be understood as a consistency constraint in the framework of FRW cosmology, and it corresponds to a very fine tuned balance between negative and positive correlations of density fluctuations and to the fastest possible decay of the normalized mass variance on large scales. By considering several galaxy samples, we discuss that these are characterized by the presence of large amplitude fluctuations with spatial extension limited only the size of the current samples. There is therefore a tension between the standard prediction of super-homogeneity and the detection of large scale inhomogeneities in the matter distribution at scales of the order of 100 Mpc/h. We discuss the theoretical implications of these results with respect to models of structure formation and to future galaxy and CMBR data, emphasizing the central role of the super-homogeneity property in the current description of fluctuations in FRW models.

description: We analyse four light curves obtained at high time resolution (~ 0.1 s) with the 11-m Southern African Large Telescope, at the ends of two normal outbursts and one superoutburst of the dwarf nova VW Hyi. All of these contain at least some Dwarf Nova Oscillations (DNOs), which, when at their highest amplitudes, are seen in unprecedented detail. In addition to the expected DNOs with periods > 20 s we find a previously unknown modulation at 13.39 s, but none at shorter periods. The various DNOs and their interaction with the longer period Quasi-periodic Oscillations are interpreted in terms of the model of magnetically controlled flow from an accretion disc proposed earlier in this series of papers. Our observations include rare DNOs very late in outburst; we find that the fundamental period does not increase beyond ~ 90 s, which is the same value that the independent ``longer period DNOs'' converge on.

Data from: Skyline fossilized birth-death model is robust to violations of sampling assumptions in total-evidence dating

description: Several total-evidence dating studies under the fossilized birth-death (FBD) model have produced very old age estimates, which are not supported by the fossil record. This phenomenon has been termed "deep root attraction (DRA)". For two specific datasets, involving divergence time estimation for the early radiations of ants, bees and wasps (Hymenoptera) and of placental mammals (Eutheria), it has been shown that the DRA effect can be greatly reduced by accommodating the fact that extant species in these trees have been sampled to maximize diversity, so called diversified sampling. Unfortunately, current methods to accommodate diversified sampling only consider the extreme case where it is possible to identify a cut-off time such that all splits occurring before this time are represented in the sampled tree but none of the younger splits. In reality, the sampling bias is rarely this extreme, and may be difficult to model properly. Similar modeling challenges apply to the sampling of the fossil record. This raises the question of whether it is possible to find dating methods that are more robust to sampling biases. Here, we show that the skyline FBD (SFBD) process, where the diversification and fossil-sampling rates can vary over time in a piecewise fashion, provides age estimates that are more robust to inadequacies in the modeling of the sampling process and less sensitive to DRA effects. In the SFBD model we consider, rates in different time intervals are either considered to be independent and identically distributed, or assumed to be autocorrelated following an Ornstein-Uhlenbeck (OU) process. Through simulations and reanalyses of the Hymenoptera and Eutheria data, we show that both variants of the SFBD model unify age estimates under random and diversified sampling assumptions. The SFBD model can resolve DRA by absorbing the deviations from the sampling assumptions into the inferred dynamics of the diversification process over time. Although this means that the inferred diversification dynamics must be interpreted with caution, taking sampling biases into account, we conclude that the SFBD model represents the most robust approach available currently for addressing DRA in total-evidence dating.
