description: Cellular differentiation is the cornerstone of metazoan development. Cell-cell signaling mechanisms are responsible for the specification of many cell fates. The response of a particular cell to a given signal is highly context dependent allowing signaling mechanisms to be reused to produce a variety of different outcomes. The EGFR and LIN-12/Notch signaling pathways are well-conserved across metazoan species and govern many fate-specification events. The specification of C. elegans Vulval Precursor Cells (VPCs) offers a powerful system to investigate how these signaling mechanisms specify cell-fates, and previous studies of VPC fate patterning have identified several forms of crosstalk between these two critical signaling mechanisms. In this thesis, I investigate how input from both the EGFR and LIN-12/Notch signaling pathways is integrated by the VPCs. I provide evidence that VPCs respond to the relative levels of LIN-12/Notch and EGFR signaling. I show that LIN-1/Elk1 is critical for VPCs to adopt discrete cell fates. In addition, I show that the Mediator components SUR-2/Med23 and the CDK-8 kinase module (CKM), in cooperation with LIN-1/Elk1, are required for an EGFR-mediated resistance to LIN-12/Notch activity. I also used CRISPR/Cas9 techniques to generate endogenous, fluorescently-tagged LAG-1 proteins. Characterization of tagged LAG-1 accumulation in the VPCs and in the somatic gonad show that LAG-1 is present in all VPCs at low levels in a lin-12/Notch independent manner. Activation of LIN-12/Notch is correlated with higher levels of LAG-1 accumulation compared to cells that do not have activated LIN-12/Notch. These findings suggest a potential autoregulation mechanism for lag-1 in certain contexts. They also suggest that endogenously tagged LAG-1 may be a useful molecular marker of LIN-12/Notch activation.
Compact Method for Proton Range Verification Based on Coaxial Prompt Gamma-Ray Monitoring: a Theoretical Study

description: Range uncertainties in proton therapy hamper treatment precision. Prompt gamma-rays were suggested 16 years ago for real-time range verification, and have already shown promising results in clinical studies with collimated cameras. Simultaneously, alternative imaging concepts without collimation are investigated to reduce the footprint and price of current prototypes. In this manuscript, a compact range verification method is presented. It monitors prompt gamma-rays with a single scintillation detector positioned coaxially to the beam and behind the patient. Thanks to the solid angle effect, proton range deviations can be derived from changes in the number of gamma-rays detected per proton, provided that the number of incident protons is well known. A theoretical background is formulated and the requirements for a future proof-of-principle experiment are identified. The potential benefits and disadvantages of the method are discussed, and the prospects and potential obstacles for its use during patient treatments are assessed. The final milestone is to monitor proton range differences in clinical cases with a statistical precision of 1 mm, a material cost of 25000 USD and a weight below 10 kg. This technique could facilitate the widespread application of in vivo range verification in proton therapy and eventually the improvement of treatment quality.

New Shapes of Primordial Non-Gaussianity from Quasi-Single Field Inflation with Multiple Isocurvatons

description: We study a simple extension of quasi-single field inflation in which the inflaton interacts with multiple extra massive scalars known as isocurvatons. Due to the breaking of time translational invariance by the inflaton background, the theory includes kinetic mixings among the inflaton and isocurvatons. These mixings give rise to novel new features in the primordial non-Gaussianities of the scalar curvature perturbation. A noteworthy feature is the amplitude of the squeezed bispectrum can grow nearly as $(k_s/k_l)^{-3}$ while oscillating as ${\rm \cosγ\log}(k_s/k_l)$, where $k_s/k_l$ is the ratio of the lengths of the short and long wavevectors. Observation of such a shape would provide evidence for the existence of multiple isocurvatons during inflation. In addition, we consider the effects of these non-Gaussianities on large-scale structure.

Integration of Taste and Odor in Agranular Insular Cortex

description: Our perception of the world is limited by the senses we are endowed with. In the case of taste, its functional fidelity is so critical for our survival that we come into the world with innate preference for sweet and disgust for bitter. These stereotyped behaviors are hardwired at the lowest levels of taste processing and they support the view that taste serves as an arbiter of the chemical world, passing judgement before permitting ingestion. Yet our experience of foods is manifold. This complexity results from distinct contributions from the sights, sounds and smells of the foods we consume. Of these, odors are a co-equal component of flavor and the impairment of olfaction can disrupt enjoyment of eating and alter patterns of consumption. The goal of this thesis is to identify the neural basis of odor-taste perception and to characterize how neural activity is affected by odor-taste integration. In contrast to the discrete and innate categorization performed by the taste system, the sense of smell enables discrimination of thousands of unique odor percepts which have no innate value. At the level of olfactory cortex, odor representations are randomly distributed and have been shown to be conditioned through association with other stimuli. The act of eating produces near simultaneous taste and odor transduction originating from the same source. Yet despite ultimately projecting to neighboring cortical regions, taste and odor pathways are anatomically segregated prior to reaching the cortex. Using viral tracing strategies, we identified Agranular Insular cortex (AIc) as a putative site of odor-taste integration. We then used in vivo two-photon Ca2+ Imaging to characterize odor and taste responsive neurons and identify changes in population activity when these stimuli were simultaneously presented. We next asked whether specific flavor experiences altered activity in AIc compared to naive animals. Finally, we developed a behavioral task to test whether silencing AIc disrupted perception of a flavor compound.

description: We investigate the effects of the electron-hole spin dynamics on the polarization fluctuations in the light emitted from a vertical cavity surface emitting laser (VCSEL). The Langevin equations are derived based on a rate equation model including birefringence, dichroism, and two carrier density pools seperately coupled to right and left circular polarization. The results show that the carrier dynamics phase lock the polarization fluctuations to the laser mode. This is clearly seen in the difference between fluctuations in ellipticity and fluctuations in polarization direction. Seperate measurements of the polarization fluctuations in ellipticity and in polarization direction can therefore provide quantitative information on the non-linear contribution of the carrier dynamics to polarization stability in VCSELs.

description: The question of how to account for the outgoing black hole modes without drawing upon a transplanckian reservoir at the horizon is addressed. It is argued that the outgoing modes must arise via conversion from ingoing modes. It is further argued that the back-reaction must be included to avoid the conclusion that particle creation cannot occur in a strictly stationary background. The process of ``mode conversion" is known in plasma physics by this name and in condensed matter physics as ``Andreev reflection" or ``branch conversion". It is illustrated here in a linear Lorentz non-invariant model introduced by Unruh. The role of interactions and a physical short distance cutoff is then examined in the sonic black hole formed with Helium-II.

description: Technology evolves quickly. Low-cost and ready-to-connect devices are designed to provide new services and applications. Smart grids or smart healthcare systems are some examples of these applications, all of which are in the context of smart cities. In this total-connectivity scenario, some security issues arise since the larger the number of connected devices is, the greater the surface attack dimension. In this way, new solutions for monitoring and detecting security events are needed to address new challenges brought about by this scenario, among others, the large number of devices to monitor, the large amount of data to manage and the real-time requirement to provide quick security event detection and, consequently, quick response to attacks. In this work, a practical and ready-to-use tool for monitoring and detecting security events in these environments is developed and introduced. The tool is based on the Multivariate Statistical Network Monitoring (MSNM) methodology for monitoring and anomaly detection and we call it MSNM-Sensor. Although it is in its early development stages, experimental results based on the detection of well-known attacks in hierarchical network systems prove the suitability of this tool for more complex scenarios, such as those found in smart cities or IoT ecosystems.

description: The social scientific study of globalization's increasing flows of commodities, financing, knowledge, media, and people has been a productive ground for investigating changing connections among geographically distant people and their consequences. In spite of this recent focus on movement and flows, however, I suggest that our knowledge of globalization is incomplete without an understanding of the infrastructures of stoppage that underlie and determine the ongoing shape and directionalities of that movement. This dissertation lays out an argument for patents as one such critical legal infrastructure of global stoppage that provides unique insight into the changing roles and challenges confronting China and Taiwan within global systems of production, consumption, creativity, and copying. The dissertation's ethnography of patents in practice is based on 20 months of fieldwork on the production of technological knowledge and property in it within a Taiwanese LED (light emitting diode) company that produces patents between Taiwan and the United States and products between Taiwan and China. I argue that the processes by which knowledge is extracted and translated from the lab to the law decouples the knowledge from its origins in machines, materials, and engineers. This decoupling enables patents to circulate separately from these and provides owners with new control over global flows of engineers, tangible commodities, and usable knowledge. Alongside my Taiwanese interlocutors, I argue that patents are best understood as weapons of competition: more similar to non-disclosure agreements or aggressive pricing tactics than copyright or other forms of “intellectual property.” As weapons, the deployment of patents encourages the production of new patents much more than it does technological innovation. As they are currently practiced, patents therefore enable flows, but do so only in particular directions. It is through this stoppage that high tech patents create and maintain global divisions of labor, profit, and environmental risk.

description: Introduction: Low immunity causes the body to become more easily infected, resulting in inflammation. If the immune system is functioning properly, this inflammation will end in healing. The immune system has a protective role in the body, and its anti-inflammatory role is vital. During trauma, the initial immune response is marked by inflammation. The use of date-seed extract, although not steeped date seeds, has been studied as an anti-inflammatory agent. This study is aimed at demonstrating the anti-inflammatory effect of steeped date seeds (Phoenix dactylifera L.) in rats with CCl4 -induced inflammation. Methods: This experiment included a pre- and post-test with control group design. Male Wistar rats (approximately 2–3 months of age, ranging in weight from 150 to 200 g) were assigned to the following groups: negative control (NC), positive control (PC), T1 treatment dose 1 g/kg, T3 treatment dose 3 g/kg, T5 treatment dose 5 g/kg, and healthy control (HC). Groups 1–5 were subjected to CCl4 induction at a single dose of 2 mL/kg before treatment. The levels of tumor necrosis factor (TNF-α), glutathione (GSH), and gamma interferon (IFN-γ) were compared in groups using one-way analysis of variance (ANOVA), followed by a least significant difference (LSD) post hoc test for comparisons between means. Results: Levels of tumor necrosis factor (TNF-α), GSH, and IFN-γ were significantly different among the HC and treatment groups after CCl4 induction. After 14 days of steeped date-seed treatment, TNF-α decreased, but GSH and IFN-γ levels increased significantly (P = 0.001). Conclusion: Administration of steeped date seeds at a dose of 5 g/kg can increase GSH and IFN-γ, and decrease TNF-α, the strongest inflammatory marker in CCl4 -induced rats. The findings of this study indicate that date-seed supplementation can support body immunity by regulating proinflammatory mediators.
Factors influencing density and composition of vegetative cover on waste rock sites at Highland Valley Copper

description: Highland Valley Copper is a large porphyry copper-molybdenum mine located in the southern interior of British Columbia. Field observations indicate that the vegetative cover supported on reclaimed sites is often variable, despite apparent similar growing conditions. A field program was undertaken at Highland Valley Copper to evaluate surface and subsurface factors that may influence the success of vegetation cover development on reclaimed sites. The program included sites where vegetation was established directly on waste rock material, and sites reclaimed on an overburden cap. The results of the program indicate that material characteristics are especially important for the upper 1 metre of the reclaimed site. The available water storage capacity, influenced by soil depth, coarse fragment content and soil texture is the most important factor that influences the reclamation potential of a site. These findings verify that site preparation activities are critical to the development of successful reclamation sites, and that monitoring to ensure placement of appropriate material on the dump surface will enhance the reclamation potential of sites.

description: The nearby Perseus galaxy cluster is a key target for indirect detection searches for decaying dark matter. We use the C-EAGLE simulations of galaxy clusters to predict the flux, width and shape of a dark matter decay line, paying particular attention to the unexplained 3.55keV line detected in the spectra of some galaxies and clusters, and the upcoming XRISM X-ray observatory mission. We show that the line width in C-EAGLE clusters similar to Perseus is typically [600-800]$\mathrm{kms^{-1}}$, and therefore narrower than the amplitude of the velocity dispersion of galaxies in the cluster. Haloes that are significantly disturbed can, however, exhibit galaxy velocity dispersions higher than $1000\mathrm{kms^{-1}}$, and in this case will show a large difference between the line profiles of on- and off-center observations. We show that the line profile is likely to be slightly asymmetric, but still well approximated by a Gaussian at the 10% level, and that the halo asymmetry can lead to fluxes that vary by a factor of two. In summary, we predict that, if the previously reported 3.55keV line detections do originate from dark matter decay, the XRISM mission will detect a line with a roughly Gaussian profile at a rest frame energy of 3.55keV, with a width $>600\mathrm{kms^{-1}}$ and flux approximately in the range $[4-9]\times10^{-8}\mathrm{counts/sec/cm^{2}}$.

This means that in the vicinity of a solution the Lieb-Wu equations are non-degenerate, if the corresponding wave function is non-zero. We further derive an action that generates the Lieb-Wu equations and express our determinant formula for the square of the norm in terms of the Hessian determinant of this action.

Macroscopic forcing method: a tool for turbulence modeling and analysis of closures

Publisher: name: arXiv
Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: This study presents a numerical procedure, which we call the macroscopic forcing method (MFM), which reveals the differential operators acting on the mean fields of quantities transported by underlying fluctuating flows. Specifically, MFM can precisely determine the eddy diffusivity operator, or more broadly said, it can reveal differential operators associated with turbulence closure for scalar and momentum transport. We present this methodology by considering canonical problems with increasing complexity. Starting from the well-known problem of dispersion of passive scalars by parallel flows we elucidate the basic steps in quantitative determination of the eddy viscosity operators using MFM. Utilizing the operator representation in Fourier space, we obtain a stand-alone compact analytical operator that can accurately capture the nonlocal mixing effects. Furthermore, a cost-effective generalization of MFM for analysis of nonhomogeneous and wall-bounded flows is developed and is comprehensively discussed through a demonstrative example. Extension of MFM for analysis of momentum transport is theoretically constructed through the introduction of a generalized momentum transport equation. We show that closure operators obtained through MFM analysis of this equation provide the exact RANS solutions obtained through averaging of the Navier-Stokes equation. We introduce MFM as an effective tool for quantitative understanding of non-Boussinesq effects and assessment of model forms in turbulence closures, particularly, the effects associated with anisotropy and nonlocality of macroscopic mixing.

Numeracy

description: Quantitative literacy, or numeracy, has been discussed as an essential component of mathematics instruction. In recent years community colleges around the nation introduced a quantitative literacy alternative to the developmental algebra curriculum for students placed into remedial mathematics. The QL curriculum consists of problem situations that are meant to improve numeracy through a combination of collaborative work and a student-centered pedagogy. There is little research that investigates the enactment of that curriculum.
      Research in K-12 indicates that teachers’ beliefs influence the enactment of curriculum, but studies that connect instructional practices and faculty beliefs are scarce. This study employs a multiple qualitative case study approach to investigate the alignment between four community college instructors’ beliefs about teaching, learning, the nature of mathematics, and curriculum on their enacted practices in two different developmental mathematics courses at a large urban community college (UCC). One is a standard developmental algebra curriculum and the other curriculum is based on quantitative literacy.
      Data were collected through semi-structured interviews, classroom observations and field notes. The results indicate an alignment between the professed beliefs and enacted practices for all but one instructor in this study. The findings imply that curriculum plays a significant role when its intended design correlates with instructors’ belief systems. The study also discusses the differences in instructional practices across the quantitative literacy and elementary algebra curricula taught by the instructors in this study.

description: In this Letter we consider the radial infall along the symmetry axis of an ultra-relativistic point particle into a rotating Kerr black hole. We use the Sasaki-Nakamura formalism to compute the waveform, energy spectra and total energy radiated during this process. We discuss possible connections between these results and the black hole-black hole collision at the speed of light process.

Interactions and Disorder in Novel Condensed Matter Systems
Creators: Lemonik, Yonah Shalom
Publisher: name: Columbia University
Year: 2015
Subjects: Condensed matter

description: Despite almost a century of exploration, we continue to discover new systems where quantum mechanics, strong interactions and disorder combine in novel ways. These systems test the capabilities of our strongest theoretical tools. In this thesis I discuss work on three of these systems: bilayer graphene, disordered conductors and cold atom systems. In bilayer graphene I show that the large number of degenerate bands leads to a plethora of possible spontaneous symmetry breaking ground state. In disordered conductors I discuss how quantum interference can lead to arbitrarily long lived responses, so called memory eects. I also consider whether a novel spontaneous symmetry breaking state can be created in cold atomic gasses using nonequilibrium perturbations.

description: The recently established agreement between experiment and theory for the $g$ factors of lithiumlike silicon and calcium ions manifests the most stringent test of the many-electron bound-state quantum electrodynamics (QED) effects in the presence of a magnetic field. In this Letter, we present a significant simultaneous improvement of both theoretical $g_\text{th} = 2.000\,889\,894\,4\,(34)$ and experimental $g_\text{exp} = 2.000\,889\,888\,45\,(14)$ values of the $g$ factor of lithiumlike silicon $^{28}$Si$^{11+}$. The theoretical precision now is limited by the many-electron two-loop contributions of the bound-state QED. The experimental value is accurate enough to test these contributions on a few percent level.

description: The Dirac oscillator is an exactly soluble model recently introduced in the context of many particle models in relativistic quantum mechanics. The model has been also considered as an interaction term for modelling quark confinement in quantum chromodynamics. These considerations should be enough for demonstrating that the Dirac oscillator can be an excellent example in relativistic quantum mechanics. In this paper we offer a solution to the problem and discuss some of its properties. We also discuss a physical picture for the Dirac oscillator's non-standard interaction, showing how it arises on describing the behaviour of a neutral particle carrying an anomalous magnetic moment and moving inside an uniformly charged sphere.

description: High-dimensional data, such as that relating to gene expression in microarray experiments, may contain substantial amount of useful information to be explored. However, the information, relevant variables and their joint interactions are usually diluted by noise due to a large number of non-informative variables. Consequently, variable selection plays a pivotal role for learning in high dimensional problems. Most of the traditional feature selection methods, such as Pearson's correlation between response and predictors, stepwise linear regressions and LASSO are among the popular linear methods. These methods are effective in identifying linear marginal effect but are limited in detecting non-linear or higher order interaction effects. It is well known that epistasis (gene - gene interactions) may play an important role in gene expression where unknown functional forms are difficult to identify. In this thesis, we propose a novel nonparametric measure to first screen and do feature selection based on information from nearest neighborhoods. The method is inspired by Lo and Zheng's earlier work (2002) on detecting interactions for discrete predictors. We apply a backward elimination algorithm based on this measure which leads to the identification of many in influential clusters of variables. Those identified groups of variables can capture both marginal and interactive effects. Second, each identified cluster has the potential to perform predictions and classifications more accurately. We also study procedures how to combine these groups of individual classifiers to form a final predictor. Through simulation and real data analysis, the proposed measure is capable of identifying important variable sets and patterns including higher-order interaction sets. The proposed procedure outperforms existing methods in three different microarray datasets. Moreover, the nonparametric measure is quite flexible and can be easily extended and applied to other areas of high-dimensional data and studies.

description: The lack of large-scale real datasets with annotations makes transfer learning a necessity for video activity understanding. We aim to develop an effective method for few-shot transfer learning for first-person action classification. We leverage independently trained local visual cues to learn representations that can be transferred from a source domain, which provides primitive action labels, to a different target domain using only a handful of examples. Visual cues we employ include object-object interactions, hand grasps and motion within regions that are a function of hand locations. We employ a framework based on meta-learning to extract the distinctive and domain invariant components of the deployed visual cues. This enables transfer of action classification models across public datasets captured with diverse scene and action configurations. We present comparative results of our transfer learning methodology and report superior results over state-of-the-art action classification approaches for both inter-class and inter-dataset transfer.

Unitary circuits of finite depth and infinite width from quantum channels

description: We introduce an approach to compute reduced density matrices for local quantum unitary circuits of finite depth and infinite width. Suppose the time-evolved state under the circuit is a matrix-product state with bond dimension $D$; then the reduced density matrix of a half-infinite system has the same spectrum as an appropriate $D\times D$ matrix acting on an ancilla space. We show that reduced density matrices at different spatial cuts are related by quantum channels acting on the ancilla space. This quantum channel approach allows for efficient numerical evaluation of the entanglement spectrum and Rényi entropies and their spatial fluctuations at finite times in an infinite system. We benchmark our numerical method on random unitary circuits, where many analytic results are available, and also show how our approach analytically recovers the behaviour of the kicked Ising model at the self-dual point. We study various properties of the spectra of the reduced density matrices and their spatial fluctuations in both the random and translation-invariant cases.

description: The Brazil nut is an important Brazilian socio-biodiversity commodity. This article analyzes production behavior and exports in the Brazilian Amazon, identifying factors that have conditioned this market behavior. Brazil nut production is concentrated in Acre, Amazonas, Pará and Rondônia states, which together account for 93.5% of Brazilian production. There is evidence of the exhaustion of native Brazil nut tree exploitation, since the extractive supply did not respond to price stimuli in recent decades. Export revenues declined, due to a reduction in quantities exported and to real exchange rate appreciation. Public funding policies and price guarantee had a limited effect on care of the Brazil nut extractivist population. This study shows that changes in sanitary regulation and Brazil nut quality control in the main trading partners had a negative effect on export performance, mainly from 2003

description: Wedelolactone, a benzofuran based natural product that can be isolated from Eclipta prostrata, exhibits a variety of biological activities. It is inefficient to obtain wedelolactone from natural sources, so it is of great significance to perform total synthesis study on this important compound. In the current study, a novel total synthesis of wedelolactone featuring palladium-catalyzed Suzuki coupling and acid-promoted intramolecular transesterification was discovered. In comparison with those reported total synthesis routes, the current strategy is more convenient and efficient, and can be used as a potential route for large scale production.
