The MAGIC Telescopes - Status and Recent Results
Creators: name: Klepser, S.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The MAGIC telescopes are two Imaging Atmospheric Cherenkov Telescopes located on the canary island of La Palma. They provide the lowest energy threshold among existing instruments of the kind, reaching down to 50 GeV in standard trigger mode. This allows us to close the energy gap between satellite-bourne and ground-based gamma-ray observations for strong enough sources. During the first five years of monoscopic observations, many interesting results could thus be achieved. With the second MAGIC telescope, which started operation in 2009, the sensitivity could be improved by stereoscopic imaging, and 5 new detections could already be reported in 2010. We present the status of the MAGIC telescopes in 2010 and review the latest results obtained in mono- and stereoscopic mode. This includes, among others, the detection of the head-tail galaxy IC 310, a new multiwavelength study of Mrk 501, an updated lightcurve of the Crab Pulsar.

Applications of Additive Manufacturing to Tissue Engineering
Creators: name: Soori, Mohsen
Publisher: name: Zenodo
Year: 2019

description: Due to rapid-fabrication of the different models, high-precision of produced parts and customized production rate of the manufacturing methodology, Additive Manufacturing (AM), 3-dimensional (3D) printing technologies and rapid prototyping (RP) systems are recently developed in many applications. Complex geometries, porosities, co-culture of multiple cells, can be created and incorporate growth factors can also be considered by using 3D printing systems. In the research work, applications of additive manufacturing systems in bioengineering products are presented. Finite element analysis can be used to analyze the mechanical properties of the structure in order to detect weak components of the entire scaffold and prevent structural failure in real working conditions. Furthermore, topology optimization methods are developed in order to obtain the best use of material for designed scaffolds which are subjected to either a single load or a multiple load distribution. As a result, “shape” optimization as well as “layout” optimization can be obtained in order to increase efficiency of part manufacturing.

title: Amazonian Women: A Multi-Voiced Narrative on Surviving Breast Cancer
Creators: name: Bowles, Melissa
Publisher: name: Utah State University
Year: 2004

description: When my mother was diagnosed with breast cancer in May of 2003, I immediately turned to journal writing and to reading to try and make sense of what was happening in my family. I searched websites for causes of breast cancer and ways to prevent it, I read literary women's memoirs, and I wrote a great deal about the way that I was feeling: scared, guilty, angry, broken. As a reader and a writer I needed to somehow intellectualize all of the things I was feeling. This writing project is a product of that initial response and of my subsequent research and experience.
Hopf algebras and finite tensor categories in conformal field theory

description: In conformal field theory the understanding of correlation functions can be divided into two distinct conceptual levels: The analytic properties of the correlators endow the representation categories of the underlying chiral symmetry algebras with additional structure, which in suitable cases is the one of a finite tensor category. The problem of specifying the correlators can then be encoded in algebraic structure internal to those categories. After reviewing results for conformal field theories for which these representation categories are semisimple, we explain what is known about representation categories of chiral symmetry algebras that are not semisimple. We focus on generalizations of the Verlinde formula, for which certain finite-dimensional complex Hopf algebras are used as a tool, and on the structural importance of the presence of a Hopf algebra internal to finite tensor categories.

description: This paper investigates situations where a property of a ring can be tested on a set of "prime right ideals." Generalizing theorems of Cohen and Kaplansky, we show that every right ideal of a ring is finitely generated (resp. principal) iff every "prime right ideal" is finitely generated (resp. principal), where the phrase "prime right ideal" can be interpreted in one of many different ways. We also use our methods to show that other properties can be tested on special sets of right ideals, such as the right artinian property and various homological properties. Applying these methods, we prove the following noncommutative generalization of a result of Kaplansky: a (left and right) noetherian ring is a principal right ideal ring iff all of its maximal right ideals are principal. A counterexample shows that the left noetherian hypothesis cannot be dropped. Finally, we compare our results to earlier generalizations of Cohen's and Kaplansky's theorems in the literature.

description: Excerpts from the report: In this report an attempt has been made to bring together facts relating to prospective world-wide and nation-wide supply and demand conditions which are not readily available to farmers. These are the conditions which will probably be encountered when products of the coming season's operations are ready for market. These statements represent, the national viewpoint and, in many instances, must be modified to meet local conditions. All available information regarding each farm product has been carefully studied and all suggestions are based on logical conclusions drawn from these facts. All statements are designed to aid farmers to make sound plans for the farming year before the time for planting and breeding. They are also designed for the use of those workers in agricultural colleges, experiment stations and extension services who prepare outlook reports for their States or regions. By using this outlook information farmers can avoid the losses which come from extreme variations in acreage, either in the form of increases or decreases. They can also plan their operations with a view to foreign competition and demand.

Timon unmasqued : Shakespeare's Timon of Athens and the ecopolitics of the Jacobean masque
Creators: name: Wang, Zhishu
Publisher: name: University of British Columbia
Year: 2022

description: Belonging to the “Tragedies” section of the Folio, Timon of Athens spotlights an Athenian lord who resorts to misanthropy after experiencing the ingratitude of his flatterers. Conventional readings of this play have largely focused on an allegorical aspect that regards Timon as a personification of Fortuna, a feminist approach by Coppélia Kahn that assigns Timon as a maternal figure, or an economic lens by Jody Greene that examines the sodomitic relationship between men. While all these directions offer critical understandings of the play, this thesis adopts methods of ecocriticism to follow Shakespeare’s ecological thinking. It aims to communicate that Timon of Athens is as much of a play about man and nature/earth as it is about man and man, as it stages both environmental issues that stem from an economy of excessive consumption and an ecology of living with nature. Through an ecocritical approach toward early modern historiography, court banquet culture, and the literary genre of Jonsonian masque, the chapters jointly demonstrate a shift in mindset toward the early modern ecological condition, through the change of nature in Timon’s character. The first chapter focuses on the early modern banquet, or the “void,” which exposes itself as a cover for exploitation of nature and the New World. The second chapter examines the inconsistency of the play and reimagines it as a Jonsonian masque in terms of structure. This method of interpretation provides an alternate speculation of Timon’s change in nature but also gives prominence to the Shakespearean ecological contemplations. Together, the chapters present a shift from ideologies of anthropocentrism and exploitative consumption of nature to a sense of recognition and consciousness of how the world operates without us and what mankind’s place is in nature.
Nonproportional response of LaBr3:Ce and LaCl3:Ce scintillators to synchrotron X-ray irradiation

description: The nonproportional scintillation response of LaBr3 doped with 5% Ce3+ and of LaCl3 doped with 10% Ce3+ was measured using highly monochromatic synchrotron irradiation. To estimate the photon response, pulse height spectra at many finely spaced energy values between 9 keV and 100 keV were measured. The experiment was carried out at the X-1 beamline at the Hamburger Synhrotronstrahlungslabor (HASYLAB) synchrotron radiation facility in Hamburg, Germany. Special attention was paid to the X-ray fluorescence escape peaks as they provide us with additional information about photon response in the range 1.2 - 14.5 keV for LaBr3:Ce and 2.0 - 11.6 keV for LaCl3:Ce. A rapid variation of the photon response curve is observed near the Lanthanum K- electron binding energy for both scintillators. A dense sampling of data is performed around this energy and that data are used to apply a method, which we call K-dip spectroscopy. This method allows us to derive the electron response curves of LaBr3:Ce and LaCl3:Ce down to energies as low as 0.1 keV.

3/2 magic-angle quantization rule of flat bands in twisted bilayer graphene and relationship with the Quantum Hall effect

description: Flat band electronic modes in twisted graphene bilayers are responsible for superconducting and other highly correlated electron-electron phases. Although some hints were known of a possible connection between the quantum Hall effect and zero flat band modes, it was not clear how such connection appears. Here the electronic behavior in twisted bilayer graphene is studied using the chiral model Hamiltonian. As a result, it is proved that for high-order magic angles, the zero flat band modes converge into coherent Landau states with a dispersion $σ^2=1/3α$, where $α$ is a coupling parameter that incorporates the twist angle and energetic scales. Then it is proved that the square of the hamiltonian, which is a $2\times 2$ matrix operator, turns out to be equivalent to a two-dimensional quantum harmonic oscillator. The interlayer currents between graphene's bipartite lattices are identified with the angular momentum term while the confinement potential is an effective quadratic potential. From there it is proved a limiting quantization rule for high-order magic angles, i.e., $α_{m+1}-α_{m}=3/2$ where $m$ is the order of the angle. All these results are in very good agreement with numerical calculations.

Splitting of folded strings in AdS_3
Creators: name: Murchikova, E. M.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper we present semiclassical computations of the splitting of folded spinning strings in AdS_3, which may be of interest in the context of AdS/CFT duality. We start with a classical closed string and assume that it can split on two closed string fragments, if at a given time two points on it coincide in target space and their velocities agree. First we consider the case of the folded string with large spin. Assuming the formal large-spin approximation of the folded string solution in AdS_3, we can completely describe the process of splitting: compute the full set of charges and obtain the string solutions describing the evolution of the final states. We find that, in this limit, the world surface does not change in the process and the final states are described by the solutions of the same type as the initial string, i.e. the formal large-spin approximation of the folded string in AdS_3. Then we consider the general case --- splitting of string given by the exact folded string solution. We find the expressions for the charges of the final fragments, the coordinate transformations diagonalizing them and, finally, their energies and spins. Due to the complexity of the initial string profile, we cannot find the solutions describing the evolution of the final fragments, but we can predict their qualitative behavior. We also generalize the results to include circular rotations and windings in S^5.

Novel spin-liquid states in the frustrated Heisenberg antiferromagnet on the honeycomb lattice

description: Recent experiment on a honeycomb-lattice Heisenberg antiferromagnet (AF) Bi$_3$Mn$_4$O$_{12}$(NO$_3$) revealed a novel spin-liquid-like behavior down to low temperature, which was ascribed to the frustration effect due to the competition between the AF nearest- and next-nearest-neighbor interactions $J_1$ and $J_2$. Motivated by the experiment, we study the ordering of the $J_1$ -$J_2$ frustrated classical Heisenberg AF on a honeycomb lattice both by a low-temperature expansion and a Monte Carlo simulation. The model has been known to possess a massive degeneracy of the ground state, which, however, might be lifted due to thermal fluctuations leading to a unique ordered state, the effect known as 'order-by-disorder'. We find that the model exhibits an intriguing ordering behavior, particularly near the AF phase boundary. The energy scale of the order-by-disorder is suppressed there down to extremely low temperatures, giving rise to exotic spin-liquid states like a "ring-liquid" or a "pancake-liquid" state accompanied by the characteristic spin structure factor and the field-induced antiferromagnetism. We argue that the recent experimental data are explicable if the system is in such exotic spin-liquid states.
title: Meanings Transferred Through the Consumption of Jewelry in Romania
Creators: name: Call, Meagan
Publisher: name: Utah State University
Year: 2004

description: In the past decade, there has been a vast expansion and globalization of markets. This "globalization demands that consumer researchers have experience and knowledge about individual countries and international conditions" (Arnould et al, 2002). The globalization of consumer research "demands that.. .researchers have experience and knowledge about individual countries and international conditions ... meaningful synthesis and comparison demands not just proficiency in statistical methods and languages but insights into cultural differences" (Arnould et al, 2002). What is important for marketers to understand is the relationship between culture and product meanings. One important area of meanings involves personal meanings such as those high involvement products consumers might use to define who they are, such as jewelry. In Belk' s famous essay "Possessions and the Extended Self", he concludes that we regard possessions as part of ourselves, that we are what we own, what we have (Belk, 1988). Our possessions are a manifestation of our characters. This paper seeks to expand cultural understanding of personal possessions through analysis of the meanings that are transferred through the consumption of jewelry in Romania.
Beam deflection and negative drag in a moving nonlinear medium

description: Light propagating in a moving medium with refractive index other than unity is subject to light drag. While the light drag effect due to the linear refractive index is often negligibly small, it can be enhanced in materials with a large group index. Here we show that the nonlinear refractive index can also play a crucial role in propagation of light in moving media and results in a beam deflection that might be confused with the transverse drag effect. We perform an experiment with a rotating ruby crystal which exhibits a very large negative group index and a positive nonlinear refractive index. The negative group index drags the light opposite to the motion of the medium. However, the positive nonlinear refractive index deflects the beam towards the motion of the medium and hinders the observation of the negative drag effect. Hence, we show that it is necessary to measure not only the transverse shift of the beam, but also its output angle to discriminate the light-drag effect from beam deflection -- a crucial step missing in earlier experiments.

description: We present results of a study of the virial state of high redshift dark matter haloes in an N-body simulation. We find that the majority of collapsed, bound haloes are not virialized at any redshift slice in our study ($z=15-6$) and have excess kinetic energy. At these redshifts, merging is still rampant and the haloes cannot strictly be treated as isolated systems. To assess if this excess kinetic energy arises from the environment, we include the surface pressure term in the virial equation explicitly and relax the assumption that the density at the halo boundary is zero. Upon inclusion of the surface term, we find that the haloes are much closer to virialization, however, they still have some excess kinetic energy. We report trends of the virial ratio including the extra surface term with three key halo properties: spin, environment, and concentration. We find that haloes with closer neighbors depart more from virialization, and that haloes with larger spin parameters do as well. We conclude that except at the lowest masses ($M < 10^6 \Msun$), dark matter haloes at high redshift are not fully virialized. This finding has interesting implications for galaxy formation at these high redshifts, as the excess kinetic energy will impact the subsequent collapse of baryons and the formation of the first disks and/or baryonic structures.

description: We present a novel construction for a Higgs-VEV sensitive operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem. Our operator does not contain any degrees of freedom charged under the SM gauge symmetries, leading to reduced tuning in the resulting models. Our construction is based on the extension of a two Higgs doublet model (2HDM) with a softly broken approximate global $D_8$ symmetry (the symmetry group of a square). A cosmic crunching model based on our extended Higgs sector has only a percent level tuning corresponding to the usual little hierarchy problem. In large regions of parameter space the 2HDM is naturally pushed towards the alignment limit. A complete model requires the introduction of fermionic top partners to ensure the approximate $D_8$ symmetry in the fermion sector. We also show that the same extended Higgs sector can be used for a novel implementation of the seesaw mechanism of neutrino masses.

title: Farmland Preservation in Cache Valley: Purchase of Agricultural Conservation Easements
Creators: name: Gittins, Jeffry Rulon
Publisher: name: Utah State University
Year: 2004

description: As farmland in Cache Valley continues to be overtaken by development each year, local farmers are looking for ways to protect their farmland from the encroaching urbanization. In recent years, funding has become available for purchase of agricultural conservation easements (PACE) programs. Although these programs are quite new to Cache Valley, they have the potential to be an effective tool in farmland preservation. This report looks at the implementation of PACE programs in Cache Valley and is divided into five main sections: a discussion of farmland loss in Cache Valley, an explanation of purchase of agricultural conservation easements programs, descriptions of organizations that support PACE programs, examples of PACE programs successfully protecting farmland in Cache Valley, and a discussion on problems currently affecting PACE programs in Cache Valley.

description: Dear New Junior Lab Technician,
Welcome to Dr. Barnard's laboratory. My name is Jared Burton, and I am currently in medical school. I wanted to write a little bit to give you a "heads-up" about what you should expect working here. I worked in this lab for three years. I picked up quite a bit of experience and research time during my employment here. It was a good, on-campus job. I thought I would write a little manual to be kept in the lab, with the hopes that some future employee will benefit from it, and not be quite as lost as I was when I first began.
When I was first taken on as a junior research technician, I didn't have much information given me. I was mainly listening to and observing my supervisor and taking copious notes. Much of my experience came through trial and error, as I am sure much of yours will, too. However, it is my hope that this manual will provide you with much of the information you need not only to begin your job here on the right foot, but also to assist you in staying on track and to help you to get as much knowledge and experience as possible from this lab experience. If you let it, the job will be a valuable learning experience.
Sincerely,
Jared Burton

description: To what extent is the volume of urban bicycle traffic affected by the provision of bicycle infrastructure? In this study, we exploit a large dataset of observed bicycle trajectories in combination with a fine-grained representation of the Copenhagen bicycle-relevant network. We apply a novel model for bicyclists' choice of route from origin to destination that takes the complete network into account. This enables us to determine bicyclists' preferences for a range of infrastructure and land-use types. We use the estimated preferences to compute a subjective cost of bicycle travel, which we correlate with the number of bicycle trips across a large number of origin-destination pairs. Simulations suggest that the extensive Copenhagen bicycle lane network has caused the number of bicycle trips and the bicycle kilometers traveled to increase by 60% and 90%, respectively, compared with a counterfactual without the bicycle lane network. This translates into an annual benefit of EUR 0.4M per km of bicycle lane owing to changes in subjective travel cost, health, and accidents. Our results thus strongly support the provision of bicycle infrastructure.

description: The description of the structure of proton is fundamental in order to describe the standard model processes at the LHC as well as for the searching of New Physics. Quantum fluctuations imply the presence of photons and leptons inside the proton, which admit a parton distribution function (PDF). Although the lepton PDFs are expected to be small, its presence opens new production mechanisms. In order to explore the lepton - induced processes at the LHC, a precise determination of the leptonic content of the proton is needed. In this paper we propose to constrain the content of charged leptons inside the proton through the study of the QED Compton scattering in ultraperipheral proton - nucleus collisions at the LHC. We estimate the total cross sections and associated distributions considering different models for the lepton PDFs and distinct lepton flavours. We demonstrate that a future experimental analysis of this process is feasible and that it can be used to constrain the content of electrons, muons and taus inside the proton.

Identification of cell type marker genes of the brain and their use in estimation of cell type proportions
Creators: name: Mancarci, Burak Ogan
Publisher: name: University of British Columbia
Year: 2022

description: Establishing the molecular diversity of cell types is crucial for the study of the nervous system. I compiled a cross-laboratory database of mouse brain cell type-specific transcriptomes from 36 major cell types from across the mammalian brain using rigorously curated published data from pooled cell type microarray and single-cell RNA-sequencing (RNA-seq) studies. I used these data to identify cell type-specific marker genes, discovering a substantial number of novel markers, many of which we validated using computational and experimental approaches. By examining datasets with known cell type proportion differences, I further demonstrate that summarized expression of marker gene sets (MGSs) in bulk tissue data can be used to estimate the relative cell type abundance across samples. Using this approach, I show that majority of genes previously reported as differentially expressed in Parkinson’s disease can be attributed to the reduction in dopaminergic cell number rather than regulatory events. To facilitate use of this expanding resource, I provide a user-friendly web interface at www.neuroexpresso.org.
Fermionic entanglement ambiguity in non-inertial frames

description: We analyse an ambiguity in previous works on entanglement of fermionic fields in non-inertial frames. This ambiguity, related to the anticommutation properties of field operators, leads to non-unique results when computing entanglement measures for the same state. We show that the ambiguity disappears when we introduce detectors, which are in any case necessary as a means to probe the field entanglement.

title: Modulation of L-Type (CaV1.3) Calcium Channels
Creators: name: Thomas, Brian
Publisher: name: Utah State University
Year: 2005

description: L-type CaV1.3 calcium channels perform critical functions in auditory hair cells, cardiac pacemaker cells, and pancreatic β-cells, but little is currently known about how these channels are modulated by cell signaling mechanisms. To begin to address this issue, we have tested the ability of various G protein-coupled receptors (GPCRs) to modulate CaV1.3 expressed in a mammalian cell line. Expression plasmids encoding CaV1.3 and auxiliary calcium channel subunits α2-δb and β3 were transiently coexpressed in HEK293 cells along with plasmids encoding a single type of GPCR. As a control for functional expression of the GPCR, we performed parallel transfections of separate HEK293 cells with N-type calcium channels (CaV2.2), which display modulation by most GPCRs. Whole-cell patch-clamp recordings were used to monitor calcium channel activity under control conditions and during agonist-dependent receptor activation. Our results indicate that Gαq/11-coupled receptors (α1A-adrenergic, H1 histamine, M1 muscarinic acetylcholine, and neurokinin 1 (NK1) receptors) trigger profound inhibition of CaV1.3, whereas Gαi/o-coupled receptors (M2 muscarinic acetylcholine) and Gαs-coupled receptors (β2 adrenergic and D1 dopamine receptor) have no apparent effects on CaV1.3 activity. These results suggest that, in vivo, CaV1.3 may be modulated exclusively by Gαq/11-coupled GPCRs. This information may ultimately be useful in identifying pharmacological treatments for cardiac arrhythmias and disorders of hearing or insulin secretion.

title: Identification of Key Genes Required for Abiotic Stress Response in Arabidopsis thaliana
Creators: name: Endo, Saori
Publisher: name: Utah State University
Year: 2005

description: To identify key genes that are required for stress response, a reverse genetics approach was taken to manipulate expression of candidate genes in plants. In this project, two potential regulatory genes which were originally identified as stress-responsive genes from a microarray experiment in Arabidopsis were examined for their roles in stress tolerance. Over-expression of gene A, which was up-regulated under stress conditions based on the array data, caused earlier flowering and improved plant growth under salinity and dehydration stress conditions at the seedling stage. Over-expression of gene B, which was down-regulated under stress conditions based on the array data, resulted in greater susceptibility to salt and dehydration stress. The null-function mutant of gene A did not show a difference in stress tests compared to control plants, presumably due to functional redundancy of other genes in plants. We propose gene A can potentially be used for stress tolerance improvement in crops.
Bubble collapse near porous plates

description: The collapse of a gas or vapour bubble near a non-porous boundary is directed at the boundary due to the asymmetry induced by the nearby boundary. High surface pressure and shear stress from this collapse can damage, or clean, the surface. A porous boundary, such as a filter, would act similarly to a non-porous boundary but with reduced asymmetry and thus reduced effect. Prior research has measured the cleaning effect of bubbles on filters using ultrasonic cleaning, but it is not known how the bubble dynamics are fundamentally affected by the porosity of the surface. We address this question experimentally by investigating how the standoff distance, porosity, pore size, and pore shape affect two collapse properties: bubble displacement and bubble rebound size. We show that these properties depend primarily on the standoff distance and porosity of the boundary and extend a previously developed numerical model that approximates this behaviour. Using the numerical model in combination with experimental data, we show that bubble displacement and bubble rebound size each collapse onto respective single curves.

description: Reconstructing how all the stellar components of the Galaxy formed and assembled over time, by studying the properties of the stars which make it, is the aim of Galactic archeology. In these last years, thanks to the launch of the ESA Gaia astrometric mission, and the development of many spectroscopic surveys, we are for the first time in the position to delve into the layers of the past of our galaxy. Globular clusters (GCs) play a fundamental role in this research field since they are among the oldest stellar systems in the Milky Way (MW) and so bear witness of its entire past. In the recent years, there have been several attempts to constrain the nature of clusters (accreted or formed in the MW itself) through the analysis of kinematic spaces and to reconstruct from this the properties of the accretions events experienced by the MW through time. This work aims to test a widely-used assumption about the clustering of the accreted populations of GCs in the integrals of motions space. We analyze a set of dissipation-less N-body simulations that reproduce the accretion of one or two satellites with their GC population on a MW-type galaxy. Our results demonstrate that a significant overlap between accreted and "kinematically-heated" in-situ GCs is expected in kinematic spaces, for mergers with mass ratios of 1:10. In contrast with standard assumptions made in the literature so far, we find that accreted GCs do not show dynamical coherence, that is they do not cluster in kinematic spaces. In addition, GCs can also be found in regions dominated by stars which have a different origin (i.e. different progenitor). This casts doubt on the association between GCs and field stars that is generally made in the literature to assign them to a common origin. Our findings severely question the recovered accretion history of the MW based on the phase-space clustering of the GC population.

description: We study the spectra for a class of differential operators with asymptotically constant coefficients.These operators widely arise as the linearizations of nonlinear partial differential equations about patterns or nonlinear waves. We present a unified framework to prove the perturbation results on the related spectra. The proof is based on exponential dichotomies and the Brouwer degree theory. As applications, we employ the developed theory to study the stability of quasi-periodic solutions of the Ginzburg-Landau equation,fold-Hopf bifurcating periodic solutions of reaction-diffusion systems coupled with ordinary differential equations, and periodic annulus of the hyperbolic Burgers-Fisher model.
