LIN28B confers cancer stem-like phenotypes for neuroendocrine prostate cancer progression
Creators: name: Lovnicki, Jessica Magdalena

Year: 2019

description: Due to the increased utilization of next generation anti-androgens to treat prostate adenocarcinoma (AdPC), therapy-induced neuroendocrine prostate cancer (t-NEPC) has become more prevalent. Although the mechanisms by which t-NEPC is established are not fully understood, emerging evidence suggests that AdPC cells can gain an intermediate pluripotent stem cell (SC)-like phenotype that can promote t-NEPC development. However, it remains unclear whether the core embryonic stem cell genes (ESCs) (LIN28, POU5F1, SOX2, and NANOG) regulate the stem-like state of prostate cancer cells and the switch from luminal epithelial to neuroendocrine lineage during the transition from AdPC to t-NEPC. We hypothesize that LIN28B plays a key role in the transition from AdPC to t-NEPC, and that the overexpression of LIN28B may promote proliferation and trans-differentiation, which may contribute to t-NEPC progression. By comparing the published RNA-seq data on AdPC and t-NEPC, we found that approximately 50% of t-NEPC patient tumors have gained LIN28B and SOX2 expression. Standard molecular and cellular biology techniques were applied to characterize the functions of LIN28B and its relationship with SOX2 using t-NEPC cell and xenograft models. We found that the mRNA levels of LIN28B and SOX2 are positively correlated in patient tumors, patient derived xenografts, transgenic mice, and multiple cell models. LIN28B and SOX2 expression was confirmed to be co-upregulated in a subset of t-NEPC patients by immunohistochemistry. Using our clinically relevant t-NEPC cell/xenograft model, DuNE, we demonstrated that LIN28B is essential for stem cell-like and neuroendocrine marker expression and cell morphology. LIN28B gene depletion by CRISPR inhibited DuNE xenograft initiation and tumor growth. These LIN28B functions are mainly mediated by its inhibitory effects on the microRNA let-7d, which resulted in the upregulation of HMGA2 and HGMA2 mediated SOX2 transcription. Overall, this thesis work adds to the understanding that the LIN28B/let-7/SOX2 axis is an important signaling pathway that regulates a cancer stem-like phenotype to promote t-NEPC development. Ultimately, this knowledge pertains to the clinical implications of LIN28B in informing future therapies that will be effective for managing t-NEPC.

description: A measurement of transverse polarisation in pbar-p -> all-neutral final states would almost certainly determine a complete set of partial wave amplitudes over the mass range 1910 to 2410 MeV. This should identify all resonances in this mass range. The experiment is technically straightforward and cheap by present standards.

description: We report on the first asteroseismic analysis of solar-type stars observed by Kepler. Observations of three G-type stars, made at one-minute cadence during the first 33.5d of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: About 20 modes of oscillation can clearly be distinguished in each star. We discuss the appearance of the oscillation spectra, including the presence of a possible signature of faculae, and the presence of mixed modes in one of the three stars.

description: The Reionization Cluster Survey (RELICS) imaged 41 galaxy clusters with the Hubble Space Telescope (HST), in order to detect lensed and high-redshift galaxies. Each cluster was imaged to about 26.5 AB mag in three optical and four near-infrared bands, taken in two distinct visits separated by varying time intervals. We make use of the multiple near-infrared epochs to search for transient sources in the cluster fields, with the primary motivation of building statistics for bright caustic crossing events in gravitational arcs. Over the whole sample, we do not find any significant ($\gtrsim5 σ$) caustic crossing events, in line with expectations from semi-analytic calculations but in contrast to what may be naively expected from previous detections of some bright events, or from deeper transient surveys that do find high rates of such events. Nevertheless, we find six prominent supernova (SN) candidates over the 41 fields: three of them were previously reported and three are new ones reported here for the first time. Out of the six candidates, four are likely core-collapse (CC) SNe -- three in cluster galaxies, and among which only one was known before, and one slightly behind the cluster at $z\sim0.6-0.7$. The other two are likely Ia -- both of them previously known, one probably in a cluster galaxy, and one behind it at $z\simeq2$. Our study supplies empirical bounds for the rate of caustic crossing events in galaxy cluster fields to typical HST magnitudes, and lays the groundwork for a future SN rate study.

description: The Hot Big Bang is often considered as the origin of all matter and radiation in the Universe. Primordial nucleosynthesis (BBN) provides strong evidence that the early Universe contained a hot plasma of photons and baryons with a temperature $T>\text{MeV}$. However, the earliest probes of dark matter originate from much later times around the epoch of structure formation. In this work we describe a scenario in which dark matter (and possibly dark radiation) can be formed around or even after BBN in a second Big Bang which we dub the ``Dark Big Bang''. The latter occurs through a phase transition in the dark sector which transforms dark vacuum energy into a hot dark plasma of particles; in this paper we focus on a first-order phase transition for the Dark Big Bang. The correct dark matter abundance can be set by dark matter cannibalism or by pair-annihilation within the dark sector followed by a thermal freeze-out. Alternatively ultra-heavy ``dark-zilla'' dark matter can originate directly from bubble collisions during the Dark Big Bang. We will show that the Dark Big Bang is consistent with constraints from structure formation and the Cosmic Microwave Background (CMB) if it occurred when the Universe was less than one month old, corresponding to a temperature in the visible sector above $\mathcal{O}$(keV). While the dark matter evades direct and indirect detection, the Dark Big Bang gives rise to striking gravity wave signatures to be tested at pulsar timing array experiments. Furthermore, the Dark Big Bang allows for realizations of self-interacting and/or warm dark matter which suggest exciting discovery potential in future small-scale structure observations.

description: One of the key tasks in the economy is forecasting the economic agents' expectations of the future values of economic variables using mathematical models. The behavior of mathematical models can be irregular, including chaotic, which reduces their predictive power. In this paper, we study the regimes of behavior of two economic models and identify irregular dynamics in them. Using these models as an example, we demonstrate the effectiveness of evolutionary algorithms and the continuous deep Q-learning method in combination with Pyragas control method for deriving a control action that stabilizes unstable periodic trajectories and suppresses chaotic dynamics. We compare qualitative and quantitative characteristics of the model's dynamics before and after applying control and verify the obtained results by numerical simulation. Proposed approach can improve the reliability of forecasting and tuning of the economic mechanism to achieve maximum decision-making efficiency.

description: We present UV and Ly$α$ radial surface brightness (SB) profiles of Ly$α$ emitters (LAEs) at $z=2.84$ detected with the Hyper Suprime-Cam (HSC) on the Subaru Telescope. The depth of our data, together with the wide field coverage including a protocluster, enable us to study the dependence of Ly$α$ halos (LAHs) on various galaxy properties, including Mpc-scale environments. UV and Ly$α$ images of 3490 LAEs are extracted, and stacking the images yields SB sensitivity of $\sim1\times10^{-20}\mathrm{~erg~s^{-1}~cm^{-2}~arcsec^{-2}}$ in Ly$α$, reaching the expected level of optically thick gas illuminated by the UV background at $z\sim3$. Fitting of the two-component exponential function gives the scale-lengths of $1.56\pm0.01$ and $10.4\pm0.3$ pkpc. Dividing the sample according to their photometric properties, we find that while the dependence of halo scale-length on environment outside of the protocluster core is not clear, LAEs in the central regions of protoclusters appear to have very large LAHs which could be caused by combined effects of source overlapping and diffuse Ly$α$ emission from cool intergalactic gas permeating the forming protocluster core irradiated by active members. For the first time, we identify ``UV halos'' around bright LAEs which are probably due to a few lower-mass satellite galaxies. Through comparison with recent numerical simulations, we conclude that, while scattered Ly$α$ photons from the host galaxies are dominant, star formation in satellites evidently contributes to LAHs, and that fluorescent Ly$α$ emission may be boosted within protocluster cores at cosmic noon and/or near bright QSOs.

description: We define \emph{piecewise rank 1} manifolds, which are aspherical manifolds that generally do not admit a nonpositively curved metric but can be decomposed into pieces that are diffeomorphic to finite volume, irreducible, locally symmetric, nonpositively curved manifolds with $π_1$-injective cusps. We prove smooth (self) rigidity for this class of manifolds in the case where the gluing preserves the cusps' homogeneous structure. We compute the group of self homotopy equivalences of such a manifold and show that it can contain a normal free abelian subgroup and thus, can be infinite. Elements of this abelian subgroup are twists along elements in the center of the fundamental group of a cusp.

description: As air traffic grows significantly, aircraft accidents increase. Many aviation accidents could be prevented if the precise aircraft positions and weather conditions on the aircraft's route were known. Existing studies propose determining the precise aircraft positions via a VHF channel with an air-to-air radio relay system that is based on mobile ad-hoc networks. However, due to the long propagation delay, the existing TDMA MAC schemes underutilize the networks. The existing TDMA MAC sends data and receives ACK in one time slot, which requires two guard times in one time slot. Since aeronautical communications spans a significant distance, the guard time occupies a significantly large portion of the slot. To solve this problem, we propose a piggybacking mechanism ACK. Our proposed MAC has one guard time in one time slot, which enables the transmission of more data. Using this additional data, we can send weather conditions that pertain to the aircraft's current position. Our analysis shows that this proposed MAC performs better than the existing MAC, since it offers better throughput and network utilization. In addition, our weather condition notification model achieves a much lower transmission delay than a HF (high frequency) voice communication.

description: Bulges are commonly believed to form in the dynamical violence of galaxy collisions and mergers. Here we model the stellar kinematics of the Bulge Radial Velocity Assay (BRAVA), and find no sign that the Milky Way contains a classical bulge formed by scrambling pre-existing disks of stars in major mergers. Rather, the bulge appears to be a bar, seen somewhat end-on, as hinted from its asymmetric boxy shape. We construct a simple but realistic N-body model of the Galaxy that self-consistently develops a bar. The bar immediately buckles and thickens in the vertical direction. As seen from the Sun, the result resembles the boxy bulge of our Galaxy. The model fits the BRAVA stellar kinematic data covering the whole bulge strikingly well with no need for a merger-made classical bulge. The bar in our best fit model has a half-length of ~ 4kpc and extends 20 degrees from the Sun-Galactic Center line. We use the new kinematic constraints to show that any classical bulge contribution cannot be larger than ~ 8% of the disk mass. Thus the Galactic bulge is a part of the disk and not a separate component made in a prior merger. Giant, pure-disk galaxies like our own present a major challenge to the standard picture in which galaxy formation is dominated by hierarchical clustering and galaxy mergers.

description: Quantum simulations of the Bose-Hubbard model (BHM) at commensurate filling can follow spreading of correlations after a sudden quench for times long enough to estimate their propagation velocities. In this work we perform tensor network simulation of the quantum Kibble-Zurek (KZ) ramp from the Mott towards the superfluid phase in the square lattice BHM and demonstrate that even relatively short ramp/quench times allow one to test the power laws predicted by the KZ mechanism (KZM). They can be verified for the correlation length and the excitation energy but the most reliable test is based on the KZM scaling hypothesis for the single particle correlation function: the correlation functions for different quench times evaluated at the same scaled time collapse to the same scaling function of the scaled distance. The scaling of the space and time variables is done according to the KZ power laws.

description: In a consistent heterotic string theory, the Kalb-Ramond field, which is the source of spacetime torsion, is augmented by Yang-Mills and gravitational Chern-Simons terms. When compactified to 4-dimensions and in the field theory limit, such additional terms give rise to interactions with interesting astrophysical predictions like rotation of plane of polarization for electromagnetic and gravitational waves. On the other hand, if one is also interested in coupling 2 or 3-form (Abelian or non-Abelian) gauge fields to torsion, one needs another class of interaction. In this paper, we shall study this interaction and offer some astrophysical and cosmological predictions. We also comment on the possibility of such terms in loop quantum gravity where, if the Barbero-Immirzi parameter is promoted to a field, acts as a source for torsion.

Stochastic Approximation and Modern Model-Based Designs for Dose-Finding Clinical Trials

description: In 1951 Robbins and Monro published the seminal article on stochastic approximation and made a specific reference to its application to the "estimation of a quantal using response, nonresponse data." Since the 1990s, statistical methodology for dose-finding studies has grown into an active area of research. The dose-finding problem is at its core a percentile estimation problem and is in line with what the Robbins--Monro method sets out to solve. In this light, it is quite surprising that the dose-finding literature has developed rather independently of the older stochastic approximation literature. The fact that stochastic approximation has seldom been used in actual clinical studies stands in stark contrast with its constant application in engineering and finance. In this article, I explore similarities and differences between the dose-finding and the stochastic approximation literatures. This review also sheds light on the present and future relevance of stochastic approximation to dose-finding clinical trials. Such connections will in turn steer dose-finding methodology on a rigorous course and extend its ability to handle increasingly complex clinical situations.

description: Patch-based physical attacks have increasingly aroused concerns. However, most existing methods focus on obscuring targets captured on the ground, and some of these methods are simply extended to deceive aerial detectors. They smear the targeted objects in the physical world with the elaborated adversarial patches, which can only slightly sway the aerial detectors' prediction and with weak attack transferability. To address the above issues, we propose to perform Contextual Background Attack (CBA), a novel physical attack framework against aerial detection, which can achieve strong attack efficacy and transferability in the physical world even without smudging the interested objects at all. Specifically, the targets of interest, i.e. the aircraft in aerial images, are adopted to mask adversarial patches. The pixels outside the mask area are optimized to make the generated adversarial patches closely cover the critical contextual background area for detection, which contributes to gifting adversarial patches with more robust and transferable attack potency in the real world. To further strengthen the attack performance, the adversarial patches are forced to be outside targets during training, by which the detected objects of interest, both on and outside patches, benefit the accumulation of attack efficacy. Consequently, the sophisticatedly designed patches are gifted with solid fooling efficacy against objects both on and outside the adversarial patches simultaneously. Extensive proportionally scaled experiments are performed in physical scenarios, demonstrating the superiority and potential of the proposed framework for physical attacks. We expect that the proposed physical attack method will serve as a benchmark for assessing the adversarial robustness of diverse aerial detectors and defense methods.

description: There were two questions to which Throckmorton gave his best efforts as a member of the Texas Legislature, as Governor, and as United States Congressman, one of which was that of frontier protection, and the other was that of railroad building. His services to Texas, in the first instance, and to Texas and the South, in the second, were undeniably distinguished. [...] Though Throckmorton's career is important for these things, its real significance in Texas history lies perhaps more in the myriad of services which he performed, rather than in the magnitude of any one in particular. For forty-four years, 1850-1894, he was connected, directly or indirectly, with the affairs of state, and for twenty-five of those years he held political office. Not only did he hold office, but he exercised great influence. At no time during this period, especially after 1860, did a politician of Texas ponder a move without first determining what "Old Throck" would think of it
Mailing back pesos and politics : the impact of remittances on political behaviour and preferences in Ilocos, Philippines
Creators: name: Ferrer, Phebe Minelle M.
Publisher: name: University of British Columbia

description: The monetary remittances sent by migrants back to their families are often conceptualized in their developmental impact and democratization potential for the migrant sending country. Micro-level, political effects are consequently missed due to the existing literature’s preponderant focus on these macro-level, economic outcomes. Moreover, few studies have considered the specific impact of remittances on the political preferences of recipients. In this paper, I examine how remittances influence the political behaviour of recipients in the Ilocos Region of the Philippines. In 2017, remittances sent to the Philippines comprised approximately 10% of national GDP, with $33 billion USD in total sent to Filipino households. Of this, the Ilocos Region received an approximate 10% share of total remittances. Moreover, in 2017, the region had a 9% share in the total amount of Overseas Filipino Workers abroad. I analyze the political impact of remittances through the relational dynamic inherent in remittance-sending, and thus how the relationship maintained between the migrant sender and recipient can influence the latter’s political attitudes. I do this through a quantitative analysis of a 2016 household survey, encompassing 3,470 respondents across 158 barangays in Ilocos Norte and Ilocos Sur. Of this sample population, 32% or 1,121 respondents reported receiving remittances, mostly from one or two sources. My initial findings are focused on access to government provided services, local political participation and voting behaviour. My results strongly indicate that while remittance recipients are less likely to access government services, their perception of ease in accessing such services increases. Recipients are also more likely to have a direct personal tie to the local mayor, as well as have a member of their household in office. Finally, recipients are significantly likely to solely consider the opinions of their remittance senders when deliberating on their choice of electoral candidates.

description: The aim of the work is to manage costs under the project "City berths of St. Petersburg". To achieve this goal, the theoretical foundations of cost management, as well as the characteristics of the GKU AVT enterprise itself, and its legal and regulatory framework are considered. An analysis of the costs of this project was carried out and the most unprofitable berths were identified, as well as the need for individual berths to function. A method was proposed for managing the costs of this project, which more efficiently reflects the costs of maintaining and maintaining the city of St. Petersburg.
The object of the research is the project "City berths of St. Petersburg" GKU "AVT".
The subject of research is the cost analysis of this project.

description: General relativity predicts the existence of black holes, compact objects whose spacetimes depend on only their mass, spin, and charge in vacuum (the "no hair" theorem). As various observations probe deeper into the strong fields of black hole candidates, it is becoming possible to test this prediction. Previous work suggested that such tests can be performed by measuring whether the multipolar structure of black hole candidates has the form that general relativity demands, and introduced a family of "bumpy black hole" spacetimes to be used for making these measurements. These spacetimes have generalized multipoles, where the deviation from the Kerr metric depends on the spacetime's "bumpiness." In this paper, we show how to compute the Geroch-Hansen moments of a bumpy black hole, demonstrating that there is a clean mapping between the deviations used in the bumpy black hole formalism and the Geroch-Hansen moments. We also extend our previous results to define bumpy black holes whose {\it current} moments, analogous to magnetic moments of electrodynamics, deviate from the canonical Kerr value.

Asymptotic $\mathcal O(r)$ gauge symmetries and gauge-invariant Poincaré generators in higher spacetime dimensions

description: The asymptotic symmetries of electromagnetism in all higher spacetime dimensions $d>4$ are extended, by incorporating consistently angle-dependent $u(1)$ gauge transformations with a linear growth in the radial coordinate at spatial infinity. Finiteness of the symplectic structure and preservation of the asymptotic conditions require to impose a set of strict parity conditions, under the antipodal map of the $(d-2)$-sphere, on the leading order fields at infinity. Canonical generators of the asymptotic symmetries are obtained through standard Hamiltonian methods. Remarkably, the theory endowed with this set of asymptotic conditions turns out to be invariant under a six-fold set of angle-dependent $u(1)$ transformations, whose generators form a centrally extended abelian algebra. The new charges generated by the $\mathcal O(r)$ gauge parameter are found to be conjugate to those associated to the now improper subleading $O(r^{-d+3})$ transformations, while the standard $\mathcal O(1)$ gauge transformations are canonically conjugate to the subleading $\mathcal{O}(r^{-d+4})$ transformations. This algebraic structure, characterized by the presence of central charges, allows us to perform a nonlinear redefinition of the Poincaré generators, that results in the decoupling of all of the $u(1)$ charges from the Poincaré algebra. Thus, the mechanism previously used in $d=4$ to find gauge-invariant Poincaré generators is shown to be a robust property of electromagnetism in all spacetime dimensions $d\geq 4$.

description: We discuss a novel genetic algorithm that can be used to find global minima on the potential energy surface of disordered ceramics and alloys using a real-space symmetry adapted crossover. Due to a high number of symmetrically equivalent solutions of many alloys a conventional genetic algorithms using reasonable population sizes are unable to locate the global minima for even the smallest systems. We demonstrate the superior performance of the use of symmetry adapted crossover by the comparison of that of a conventional GA for finding global minima of two binary Ising-type alloys that either order or phase separate at low temperature. Comparison of different representations and crossover operations show that the use of real-space crossover outperforms crossover operators working on binary representations by several orders of magnitude.

description: We show that the competition between magnetism and superconductivity can be used to determine the pairing state in the iron arsenides. To this end we demonstrate that the itinerant antiferromagnetic phase (AFM) and the unconventional $s^{+-}$ sign-changing superconducting state (SC) are near the borderline of microscopic coexistence and macroscopic phase separation, explaining the experimentally observed competition of both ordered states. In contrast, conventional $s^{++}$ pairing is not able to coexist with magnetism. Expanding the microscopic free energy of the system with competing orders around the multicritical point, we find that static magnetism plays the role of an intrinsic interband Josephson coupling, making the phase diagram sensitive to the symmetry of the Cooper pair wavefunction. We relate this result to the quasiparticle excitation spectrum and to the emergent SO$(5)$ symmetry of systems with particle-hole symmetry. Our results rely on the assumption that the same electrons that form the ordered moment contribute to the superconducting condensate and that the system is close to particle-hole symmetry. We also compare the suppression of SC in different regions of the FeAs phase diagram, showing that while in the underdoped side it is due to the competition with AFM, in the overdoped side it is related to the disappearance of pockets from the Fermi surface.

description: We describe the implementation of multigrid solvers in the Athena++ adaptive mesh refinement (AMR) framework and their application to the solution of the Poisson equation for self-gravity. The new solvers are built on top of the AMR hierarchy and TaskList framework of Athena++ for efficient parallelization. We adopt a conservative formulation for the Laplacian operator that avoids artificial accelerations at level boundaries. Periodic, fixed, and zero-gradient boundary conditions are implemented, as well as open boundary conditions based on a multipole expansion. Hybrid parallelization using both MPI and OpenMP is adopted, and we present results of tests demonstrating the accuracy and scaling of the methods. On a uniform grid we show multigrid significantly outperforms methods based on FFTs, and requires only a small fraction of the compute time required by the (highly optimized) magnetohydrodynamic solver in Athena++. As a demonstration of the capabilities of the methods, we present the results of a test calculation of magnetized protostellar collapse on an adaptive mesh.
