description: The IceCube Neutrino Observatory publishes "alert events", i.e. detections of high-energy neutrinos with a moderate-to-high probability of being of astrophysical origin. While some events are produced in the atmosphere, a fraction of alert events should point back to their astrophysical sources. We aim to identify multiple alert events possibly related to a single astrophysical counterpart by searching for spatial and temporal clusterings in 13 years of alert data. We identify spatial clusters ("multiplets") by checking for events overlapping within their uncertainty regions. In order to reduce chance coincidences and to improve the signal purity of our sample, we apply different thresholds. We investigate the weighted mean position of these multiplets for an over-fluctuation of gamma-ray counterparts. As a final step, we apply expectation maximization to search for temporal clusters around the identified weighted mean positions. We find no statistically significant clustering of alert events around a specific origin direction or in time. This could be because the selections are still dominated by atmospheric background. Another possibility is that we are not yet sensitive enough and only detect single events from sources. In this case, we need more data in order to observe a clustering of events around their origin.

Fast variability of gamma-ray emission from supermassive black hole binary OJ 287

description: We report the discovery of fast variability of gamma-ray flares from blazar OJ 287. This blazar is known to be powered by binary system of supermassive black holes. The observed variability time scale T_var < 3-10 hr is much shorter than the light crossing time of more massive (1.8x10^10 solar masses) black hole and is comparable to the light crossing time of the less massive (1.3x10^8 solar masses) black hole. This indicates that gamma-ray emission is produced by relativistic jet ejected by the black hole of smaller mass. Detection of gamma rays s with energies in excess of 10 GeV during the fast variable flares constrains the Doppler factor of the jet to be larger than 4. Possibility of the study of orbital modulation of emission from relativistic jet makes OJ 287 a unique laboratory for the study of the mechanism(s) of formation of jets by black holes, in particular, of the response of the jet parameters to the changes of the parameters of the medium from which the black hole accretes and into which the jet expands.

Novel therapies in the pipeline: Directions of research into platelet inhibition
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Ischemic stroke is one of the foremost causes of death and disability in the industrialized world. Apart from both primary and secondary prevention with oral antiplatelet agents, acute treatment is currently limited to recombinant tissue plasminogen activator and interventional therapy. The occurrence of re-thrombosis during and after these interventions clearly indicate the need for further application of novel agents in the treatment of stroke.
Platelet Function:
Current antiplatelet agents in use affect platelet aggregation at different steps. The common limiting factor is the observed occurrence of intracerebral hemorrhage in the setting of acute stroke.
Platelet Inhibition:
Selective inhibition of glycoproteins has been employed already (GP IIb/IIIa inhibitors) but there are other glycoproteins that can be targeted. This is based on research that shows that monoclonal antibody mediated inhibition decreases the burden of disease in mouse models of stroke. A new drug that targets the A1 domain of activated von Willebrand factor that attaches to GP Ib is potentially another way of solving the thrombosis puzzle with the promise that intracerebral hemorrhage would be limited.

description: We investigate how gravity affects "Q-balls" with the Affleck-Dine potential $V_{AD}(ϕ):=\frac{m^2}{2}ϕ^2[ 1+K\ln (\fracϕ{M})^2]$. Contrary to the flat case, in which equilibrium solutions exist only if $K<0$, we find three types of gravitating solutions as follows. In the case that $K<0$, ordinary Q-ball solutions exist; there is an upper bound of the charge due to gravity. In the case that K=0, equilibrium solutions called (mini-)boson stars appear due to gravity; there is an upper bound of the charge, too. In the case that $K>0$, equilibrium solutions appear, too. In this case, these solutions are not asymptotically flat but surrounded by Q-matter. These solutions might be important in considering a dark matter scenario in the Affleck-Dine mechanism.

Learning through others : connecting research to professional learning
Creators: name: Hadden, Kyla Stacy
Publisher: name: University of British Columbia

description: Research shows that collaborative professional development, when driven by teacher interest and needs, may be the key to quality professional learning. However, many professional development activities offer little connection to teachers’ individual contexts and fail to offer time for engaging with research and resources, or for collaboration and reflection. The single workshop model often consists of experts telling teachers what the current research says and how it should be implemented in the classroom. These forms of professional development follow a training model and do not encourage transformational learning that “increases our cognitive, affective, interpersonal capacities so we are better able to manage the complexities of leading, teaching, learning and living” (Drago-Severson & Blum-DeStefano, 2014, p. 120). This study explored how a small group of teachers learned in a resource rich, collaborative inquiry driven by their own needs and interests. In this study, eight teachers participated in yearlong collaborative inquiry centered on the renewed curriculum in British Columbia. Through their voices, this study sought to gain insight into how this group of teachers interacted with educational research and resources as part of their professional learning and how this learning impacted both teacher learning and classroom practice. With this new knowledge, this study contributes to teacher professional development literature related to transformative professional learning for teachers.

description: Phosphorus plays an essential role in the chemistry of living organisms, being present in several fundamental biomolecules. The investigation of chemical reactions taking place in different astronomical environments involving phosphorus-containing molecules is essential for understanding how these species are produced and destroyed. Phosphorus monoxide (PO) and phosphorus nitride (PN) are key reservoirs of phosphorus in the Interstellar Medium (ISM). This work presents a computational study of the CPN system to identify viable reaction pathways involving atom-diatom collisions and to explore a potential destruction route for PN in the ISM. We explore the potential energy landscape of the C($\mathrm{^3P}$) + PN($^1Σ^+$), N($\mathrm{^4S}$) + CP($^2Σ^+$) and P($\mathrm{^4S}$) + CN($^2Σ^+$) reactions by performing high-accuracy ab initio calculations and provide their rate coefficients over a wide range of temperatures. The temperature-dependent rate coefficients were fitted to the modified Arrhenius equation: $k(T)=α(T/300)^β\mathrm{exp}(-γ/T)$. An updated chemical network for P-bearing species was used to model the time-dependent abundances and reaction contributions of P, PO, PN, and PH during the chemical evolution of diffuse/translucent and dense clouds. The only neutral-neutral reaction capable of destroying PN without an activation energy seems to be the PN+C one. We have also shown that reactions between CP and N can yield CN and PN barrierless. Chemical models indicate that PO is a crucial species driving the gas-phase formation of PN. Typically, PO/PN ratios exceed 1, though their chemistry is influenced by photon- and cosmic-ray-induced processes. Over time in simulated dense clouds, neutral-neutral reactions such as PO + N, PH + N, P + OH, and PH + O play a significant role in determining the relative abundances of PO and PN.

description: Supergiant Fast X-ray Transients (SFXT) are a sub-class of High Mass X-ray Binaries (HMXB) in which a compact object accretes part of the clumpy wind of the blue supergiant companion, triggering a series of brief, X-ray flares lasting a few kiloseconds. Currently, only about fifteen SFXTs are known. The EXTraS catalog provides the timing signatures of every source observed by the EPIC instrument on-board XMM-Newton. Among the most peculiar sources, in terms of variability, we selected 4XMM J181330.1-17511 (J1813). We analyzed all publicly available X-ray data pointed at the J1813 position to determine the source's duty cycle and to provide a comprehensive description of its timing and spectral behavior during its active phase. Additionally, we searched for the optical and infrared counterpart of the X-ray source in public databases and fitted its Spectral Energy Distribution (SED). The optical-to-MIR SED of J1813 is consistent with a highly-absorbed (A$_V\sim38$) B0 star at $\sim$10 kpc. During its X-ray active phase, the source is characterized by continuous $\sim$thousands seconds-long flares with peak luminosities (2-12 keV) ranging from $10^{34}$ to $4 \times 10^{35}$ erg s$^{-1}$. Its X-ray spectrum is consistent with a high-absorbed power-law model with N$_H \sim 1.8 \times 10^{23}$ cm$^{-2}$ and $Γ\sim 1.66$. No spectral variability was observed as a function of time or flux. J1813 is in a quiescent state $\sim$60\% of the time, with an upper-limit luminosity of $8 \times 10^{32}$ erg s$^{-1}$ (at 10 kpc), implying an observed long-term X-ray flux variability $>$500. The optical counterpart alone indicates J1813 is a HMXB. Its transient nature, duty cycle, the amplitude of observed X-ray variability, the shape and luminosity of the X-ray flares -- and the lack of known X-ray outbursts ($>10^{36}$ erg s$^{-1}$) -- strongly support the identification of J1813 as an SFXT.

description: In this paper we consider disjoint decomposition of algebraic and non-linear partial differential systems of equations and inequations into so-called simple subsystems. We exploit Thomas decomposition ideas and develop them into a new algorithm. For algebraic systems simplicity means triangularity, squarefreeness and non-vanishing initials. For differential systems the algorithm provides not only algebraic simplicity but also involutivity. The algorithm has been implemented in Maple.

description: Hyperfine induced $2s2p~^3P_0 \rightarrow 2s^2~^1S_0$ transition rates in an external magnetic field for Be-like $^{47}$Ti were calculated based on the multiconfiguration Dirac-Fock method. It was found that the transition probability is dependent on the magnetic quantum number $M_F$ of the excited state, even in the weak field. The present investigation clarified that the difference of the hyperfine induced transition rate of Be-like Ti ions between experiment [Schippers {\sl et al.}, Phys Rev Lett {\bf 98}, (2007) 033001(4)] and theory does not result from the influence of external magnetic field.

description: In order to clarify the mechanism of the enhancement of superconducting transition temperature $T_{\rm c}$ due to anharmonic local oscillation of a guest ion in a cage composed of host atoms, i.e., {\it rattling}, we analyze the anharmonic Holstein model by applying the Migdal-Eliashberg theory. From the evaluation of the normal-state electron-phonon coupling constant, it is found that the strong coupling state is developed, when the bottom of a potential for the guest ion becomes wide and flat. Then, $T_{\rm c}$ is enhanced with the increase of the anharmonicity in the potential, although $T_{\rm c}$ is rather decreased when the potential becomes a double-well type due to very strong anharmonicity. From these results, we propose a scenario of anharmonicity-controlled strong-coupling tendency for superconductivity induced by rattling. We briefly discuss possible relevance of the present scenario with superconductivity in $β$-pyrochlore oxides.

description: We extend our maximum likelihood method for reconstructing the cluster-mass cross-correlation from cosmic microwave background (CMB) temperature anisotropies and develop new estimators that utilize six different quadratic combinations of CMB temperature and polarization fields. Our maximum likelihood estimators are constructed with delensed CMB temperature and polarization fields by using an assumed model of the convergence field and they can be iteratively applied to a set of clusters, approaching to the optimal condition for the lensing reconstruction as the assumed initial model is refined. Using smoothed particle hydrodynamics simulations, we create a catalog of realistic clusters obtainable from the current Sunyaev-Zel'dovich (SZ) surveys, and we demonstrate the ability of the maximum likelihood estimators to reconstruct the cluster-mass cross-correlation from the massive clusters. The iTT temperature estimator provides a signal-to-noise ratio of a factor 3 larger than the iEB polarization estimator, unless the detector noise for measuring polarization anisotropies is controlled under 3 microK.

description: We consider the hydrodynamic behavior of some conservative particle systems with degenerate jump rates without exclusive constraints. More precisely, we study the particle systems without restrictions on the total number of particles per site with nearest neighbor exchange rates which vanish for certain configurations. Due to the degeneracy of the rates, there exists blocked configurations which do not evolve under the dynamics and all of the hyperplanes of configurations with a fixed number particles can be decomposed into different irreducible sets. We show that, for initial profiles smooth enough and bounded away from zero, the macroscopic density profile evolves under the diffusive time scaling according to a nonlinear diffusion equation (which we call the modified porous medium equation). The proof is based on the Relative Entropy method but it cannot be straightforwardly applied because of the degeneracy.

description: We introduce an analytical statistical method to characterize the communities detected in heterogeneous complex systems. By posing a suitable null hypothesis, our method makes use of the hypergeometric distribution to assess the probability that a given property is over-expressed in the elements of a community with respect to all the elements of the investigated set. We apply our method to two specific complex networks, namely a network of world movies and a network of physics preprints. The characterization of the elements and of the communities is done in terms of languages and countries for the movie network and of journals and subject categories for papers. We find that our method is able to characterize clearly the identified communities. Moreover our method works well both for large and for small communities.

description: We study the condition for optimizing superconductivity in the iron pnictides from the lattice structure point of view. Studying the band structure of the hypothetical lattice structure of LaFeAsO, the hole Fermi surface multiplicity is found to be maximized around the Fe-As-Fe bond angle regime where the arsenic atoms form a regular tetrahedron. Superconductivity is optimized within this three hole Fermi surface regime, while the stoner factor of the antiferromagnetism has an overall tendency of increasing upon decreasing the bond angle. Combining also the effect of the varying the Fe-As bond length, we provide a guiding principle for obtaining high $T_c$.

3D Printed Stretchable Electronics: Fabrication using Aerosol Jet, Fundamental Mechanics, and Applications
Creators: name: Brenneman, Jacob
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Electrical signals form the basis for information transfer in several biological systems and devices that capture these signals are of significant interest to the healthcare industry. Such devices are currently made from Si based components and metal interconnects and typically have an elastic modulus about 3-4 orders of magnitude higher than that of biological tissue. This gap has spurred the development of stretchable electronic devices where a soft platform ‘hosts’ the mechanically stiff electrical elements such as chips and interconnects, while the low elastic modulus substrate achieves a seamless interface with the biological tissue of interest. Such systems are playing an increasingly important role in emerging areas such as soft robotics and smart clothing. In this thesis, aerosol jet nanoparticle 3D printing is used to create a stretchable electronic system consisting of three-dimensional interconnects enabling multilayered connections embedded within a thin (<100 µm in thickness) biocompatible elastomer membrane where elastic modulus gradients are used to mitigate the effects of the system stress. The stretchable interconnect system chosen for this work is fabricated via a wafercompatible process consisting of silver conductor encapsulated by polyimide printed directly on a polydimethylsiloxane (PDMS) elastomer substrate, followed by thermal sintering/curing. The different ideal processing conditions for each material result in several problems including delamination between polyimide layers, low electrical conductivity, and cracking of the 3D interconnects during fabrication. The delamination problem is solved by understanding the underlying mechanisms via a hypothesis-driven experimental and theoretical investigation to identify processing conditions that can eliminate delamination. The cracking problem for silver interconnects is solved by first identifying that the cracks originate due to capillary pressure prior to sintering, followed by changes to the process to prevent their formation. Fully embedded stretchable interconnects are enabled by the development of a compatible process that retains the stretchability of the PDMS and electrical conductivity of the silver. A method to print 3D pillars that extend through the top PDMS layer is developed to create multi-layered interconnection and external connection points, and Electrocardiogram (ECG) signals are captured by a multi-layered skin-wearable device fabricated with the developed process. The research presented in this thesis aims to develop an additive fabrication method for stretchable electronics, understand the fundamental mechanics of such systems, and use this knowledge to create a high-fidelity stretchable system that can capture bioelectronic signals

description: Treatment-induced neuroendocrine trans-differentiation (NEtD) complicates therapies for metastatic prostate cancer (PCa). Based on evidence that PCa cells can transdifferentiate to other neuroectodermally-derived cell lineages in vitro, we proposed that NEtD requires first an intermediary reprogramming to metastable cancer stem-like cells (CSCs) of a neural class and we demonstrate that several different AR⁺/PSA⁺ PCa cell lines were efficiently reprogrammed to, maintained and propagated as CSCs by growth in androgen-free neural/neural crest (N/NC) stem transition medium (STM). Such reprogrammed cells lost features of prostate differentiation; gained features of N/NC stem cells including tumour-initiating potential; were resistant to androgen signaling inhibition; and acquired an invasive phenotype in vitro and in vivo. These aggressive features were linked to overexpression of N/NC master regulator Sox9, with concomitant loss of Rb1 and p53 function. Functional analysis employing Sox9 constructs phenocopied invasive and expression profiles of STM-mediated development reprogramming. Meanwhile, targeting of Sox9 and it’s upstream activators reduced aggressive features and sensitized cells to androgen signalling inhibition. Acute androgen deprivation or anti-androgen treatment of PCa cells led to the transient appearance of a sub-population of cells with similar characteristics to the developmentally reprogrammed CSCs described above. Notably, a 132-gene signature derived from reprogrammed PCa cell lines distinguished tumours from PCa patients with adverse outcomes. When placed back into serum-containing mediums, reprogrammed cells could be re-differentiated to N-/NC-derived cell lineages or re-differentiate to an AR⁺ prostate-like state. Once returned, the AR⁺ cells were resistant to androgen signaling inhibition, and had retained aggressiveness markers like NRP1 and EZH2 associated with the CSC state. This model may explain neural manifestations of PCa associated with lethal disease. The metastable nature of the reprogrammed stem-like PCa cells suggests that cycles of PCa cell reprogramming followed by re-differentiation may support disease progression and therapeutic resistance. The ability of a gene signature from reprogrammed PCa cells to identify tumours from patients with metastasis or PCa-specific mortality implies that developmental reprogramming is linked to aggressive tumour behaviors. Finally, the signature of serum return cells functioned as a recurrence model in identifying genes associated with enhanced aggressiveness in therapy resistance.

Occurence and Variability in Acute Formation of Leptomeningeal Collaterals in Proximal Middle Cerebral Artery Occlusion
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background:
We performed this study to semi-quantitatively characterize the formation of leptomeningeal collaterals in acute middle cerebral artery (MCA) occlusion caused by intravascular balloon inflation.
Methods:
The anatomic extent of leptomeningeal collateral blood flow from the anterior cerebral artery territory to the MCA territory during occlusion of the M1 segment was graded based on angiographically visible retrograde reconstitution of the MCA segments on the delayed venous phase prior to and during inflation of the balloon.
Results:
During MCA occlusion, the leptomeningeal collaterals markedly improved in 5 of 7 patients and were graded as 1 (retrograde filling of distal M1 segment) in 3 patients, 2 (retrograde filling of proximal M2 segment) in 1 patient, 4 (retrograde filling of M3 segment) in 1 patient and 5 (none or minimal) in 2 patients.
Conclusion:
Leptomeningeal collaterals from the anterior cerebral artery can form rapidly during MCA occlusion with considerable individual variability.

description: Starburst galaxies are primary feedback sources of mechanical energy and metals, which are generally measured from associated X-ray emission lines assuming that they are from the thermal emission of the outflowing hot gas. Such line emission, however, can also arise from the charge exchange X-ray emission (CXE) between highly ionized ions and neutral species. To understand the feedback of energy and metals, it is crucial to determine the origin of the X-ray emission lines and to distinguish the contributions from the CXE and the thermal emission. The origin of the lines can be diagnosed by the Kα triplets of He-like ions, because the CXE favors the inter-combination and forbidden lines, while the thermal emission favors the resonance line. We analyze the triplets of O VII, Ne IX, and Mg XI observed in the XMM- Newton reflection grating spectra of the starburst galaxy M82. The flux contribution of the CXE is 90%, 50%, and 30% to the O VII, Ne IX, and Mg XI triplet, respectively. Averaged over all the three triplets, the contribution of the CXE is \sim 50% of the total observed triplet flux. To correctly understand the hot outflow of starburst galaxies, it is necessary to include the CXE. Based on the measured CXE contributions to the O VII, Ne IX, and Mg XI triplets, we estimate the relative abundances of O, Ne, and Mg of the outflow and find they are similar to the solar ratios.

Investigating science teachers’ interpretations of motivating features of inquiry-based science curriculum and their enactment decision making
Creators: name: Witham, Shelly
Publisher: name: No Publisher Supplied
Year: 2019

description: It is challenging to motivate and deeply engage students in inquiry-based science settings. Inquiry tasks are difficult, require the coordination of deep-level learning strategies, and extend over time.  Despite these challenges, the curriculum supports found in inquiry-based curricula have the potential to provide optimal conditions for high quality motivational enactment in support of students’ basic need for autonomy.  The existing literature has not yet provided insights into how teachers draw on inquiry curriculum with autonomy-supportive features and translate it into high quality enactment.  Thus, we need information about how teachers work with, optimize, supplement and modify inquiry materials to have a fuller understanding of how their enactment supports student autonomy in optimal ways within inquiry contexts.  The purpose of this study was to (1) examine how teachers interpret and notice the autonomy supportive features provided within inquiry curricula, (2) investigate the particular modifications and revisions teachers make when considering enactment of these motivating features, and (3) explore the rationales and reasons behind these enactment decisions.  Data was collected from interviews and classroom observations from four inquiry teachers to examine how they augment, diminish, or enact as intended autonomy-supportive curriculum features.  Teachers planned to enact the curriculum as intended 78% of the time and planned modifications 22% of the time.  Encouragingly, 56% of these planned modifications enhanced student autonomy.  Reasons influencing teachers to adopt autonomy-supportive practices were driven not only by teaching pressures, but also by various supports. Implications for inquiry curriculum developers and for elaborating our understanding of autonomy-supportive practices within inquiry contexts will be discussed.  Findings underscore the importance of accounting for motivation curricular features in combination with teachers’ motivational beliefs as antecedents to their resulting motivational enactment.
Correlated bosons in a one-dimensional optical lattice: Effects of the trapping potential and of quasiperiodic disorder

description: We investigate the effect of the trapping potential on the quantum phases of strongly correlated ultracold bosons in one-dimensional periodic and quasiperiodic optical lattices. By means of a decoupling meanfield approach, we characterize the ground state of the system and its behavior under variation of the harmonic trapping, as a function of the total number of atoms. For a small atom number the system shows an incompressible Mott-insulating phase, as the size of the cloud remains unaffected when the trapping potential is varied. When the quasiperiodic potential is added the system develops a metastable-disordered phase which is neither compressible nor Mott insulating. This state is characteristic of quasidisorder in the presence of a strong trapping potential.

Preconditioners for incompressible magnetohydrodynamics
Creators: name: Wathen, Michael P.
Publisher: name: University of British Columbia
Year: 2018

description: The main goal of this thesis is to design efficient numerical solutions to incompressible magnetohydrodynamics (MHD) problems, with focus on the solution of the large and sparse linear systems that arise. The MHD model couples the Navier-Stokes equations that govern fluid dynamics and Maxwell's equations which govern the electromagnetic effects. We consider a mixed finite element discretization of an MHD model problem. Upon discretization and linearization, a large block 4-by-4 nonsymmetric linear system needs to be (repeatedly) solved. One of the principal challenges is the presence of a skew-symmetric term that couples the fluid velocity with the magnetic field. We propose two distinct preconditioning techniques. The first approach relies on utilizing and combining effective solvers for the mixed Maxwell and the Navier-Stokes sub-problems. The second approach is based on algebraic approximations of the inverse of the matrix of the linear system. Both approaches exploit the block structure of the discretized MHD problem. We perform a spectral analysis for ideal versions of the proposed preconditioners, and develop and test practical versions. Large-scale numerical results for linear systems of dimensions up to 10⁷ in two and three dimensions validate the effectiveness of our techniques. We also explore the use of the Conjugate Gradient (CG) method for saddle-point problems with an algebraic structure similar to the time-harmonic Maxwell problem. Specifically, we show that for a nonsingular saddle-point matrix with a maximally rank-deficient leading block, there are two sufficient conditions that allow for CG to be used. An important part of the contributions of this thesis is the development of numerical software that utilizes state-of-the-art software packages. This software is highly modular, robust, and flexible.

description: With the aim of characterizing rejuvenation processes in early-type galaxies, we analyzed five barred S0 galaxies showing prominent outer ring in ultraviolet (UV) imaging. We analyzed GALEX far- (FUV) and near- (NUV) UV and optical data using stellar population models and estimated the age and the stellar mass of the entire galaxies and of the UV-bright ring structures. Outer rings consist of young (<200 Myr old) stellar populations, accounting for up to 70% of the FUV flux but containing only a few % of the total stellar mass. Integrated photometry of the whole galaxies places four of these objects on the green valley, indicating a globally evolving nature. We suggest such galaxy evolution is likely driven by bar induced instabilities, i.e. inner secular evolution, that conveys gas to the nucleus and to the outer rings. At the same time, HI observations of NGC 1533 and NGC 2962 suggest external gas re-fueling can play a role in the rejuvenation processes of such galaxies.

description: NTN1 is expressed in a wide range of developmental tissues and is essential for normal development. Here we describe the generation of a Netrin-1 reporter chicken line (NTN1-T2A-eGFP) by targeting green fluorescent protein into the NTN1 locus using CRISPR/Cas9 methodology. Our strategy gave 100% transmission of heterozygous (NTN1T2A - eGFP/+) embryos in which GFP localisation faithfully replicated endogenous NTN1 expression in the optic fissure and neural tube floorplate. Furthermore, all NTN1T2A - eGFP/+ embryos and hatched birds appeared phenotypically normal. We applied this resource to a pertinent developmental context - coloboma is a structural eye malformation characterised by failure of epithelial fusion during optic fissure closure (OFC) and NTN1 is specifically expressed in fusion pioneer cells at the edges of the optic fissure. We therefore optimised the isolation of GFP expressing cells from embryonic NTN1T2A - eGFP/+ eyes using spectral fluorescence cell-sorting and applied transcriptomic profiling of pioneer cells, which revealed multiple new OFC markers and novel pathways for developmental tissue fusion and coloboma. This work provides a novel fluorescent NTN1 chicken reporter line with broad experimental utility and is the first to directly molecularly characterise pioneer cells during OFC.
