description: We outline the many physics opportunities offered by a multi-purpose fixed-target experiment using the LHC proton and Pb beams extracted by a bent crystal. In a proton run with the LHC 7-TeV beam, one can analyze pp, pd and pA collisions at sqrt(s_NN)~115 GeV and even higher using the Fermi motion in a nuclear target. In a Pb run with a 2.76 TeV-per-nucleon beam, sqrt(s_NN) is as high as 72 GeV. Bent crystals can be used to extract about 5x10^8 protons/s; the integrated luminosity over a year reaches 0.5fb-1 on a typical 1 cm-long target without species limitation. Such an extraction mode does not alter the performance of the collider experiments at the LHC. By instrumenting the target-rapidity region, gluon and heavy-quark proton and neutron PDFs can be accessed at large x and even at x larger than 1 in the nuclear case. Single diffractive physics and, for the first time, the large negative-xF domain can be accessed. The nuclear target-species versatility provides a unique opportunity to study nuclear matter vs. the features of the hot and dense matter formed in heavy-ion collisions, which can be studied in PbA collisions over the full range of target-rapidity domain with a large variety of nuclei. The polarization of hydrogen and nuclear targets allows an ambitious spin program, including measurements of the QCD lensing effects which underlie the Sivers single-spin asymmetry, the study of transversity distributions and possibly of polarized PDFs. We also emphasize the potential offered by pA ultra-peripheral collisions where the nucleus target A is used as a coherent photon source, mimicking photoproduction processes in ep collisions. Finally, we note that W and Z bosons can be produced and detected in a fixed-target experiment and in their threshold domain for the first time, providing new ways to probe the partonic content of the proton and the nucleus.

description: In the present work we have searched the existence of the late time acceleration of the Universe. The matter source that is responsible for the late time acceleration of the Universe consists of cosmic fluid with the equation of state parameter $ω=\frac{p}ρ$ and uniform magnetic field of energy density $ρ_{B}$. The study is done here under the framework of spatially homogeneous and anisotropic locally rotationally symmetric (LRS) Bianchi-I cosmological model in the presence of magnetized dark energy. To get the deterministic model of the Universe, we assume that the shear scalar $(σ)$ in the model is proportional to expansion scalar $(θ)$. This condition leads to $A=B^{n}$, where $A$ and $B$ are metric functions and $n$ is a positive constant giving the proportionality condition between shear and expansion scalar. It has been found that the isotropic distribution of magnetized dark energy leads to the present accelerated expansion of the Universe and the derived model is in good agreement with the recent astrophysical observations. The physical behavior of the Universe has been discussed in details.

description: Reactions of atomic carbon with molecular ions play a critical role for gas phase molecular formation in interstellar clouds. These interactions are the first links in the chain of chemical reactions leading to the synthesis of complex organic species. Much of our knowledge of this process is through spectroscopic observations and theoretical models. However, our understanding of this chemistry is constrained by uncertainties in the underlying reaction rate coefficients. Data from quantum calculations are limited to reactions involving three or fewer atoms. Meanwhile, previous experimental studies have been hampered by the difficulty in generating a sufficiently intense and well characterized neutral carbon beam. To address these issues and to study these reactions experimentally, we are building a novel laboratory device which does not suffer from such limitations

The teacher monologues : exploring the experiences and identities of artist-teachers

Publisher: name: University of British Columbia

description: In this research I examine the experiences of four Conservatory style trained actors, who go onto complete teacher education programs. In keeping with a/r/tography this research uses social science methods and creative methods of data collection. Interviews and reflective writing about the participant’s educational and experiential backgrounds were complimented by the writing of monologues. Themes from the data collected during interviews, reflective writing and monologues led me to understand that: there is a connection between developing consciousness and having a noetic experience; actor-teachers want to talk about their noetic experiences; residue is an a/r/tographic rendering used to describe the way that having an illuminating experience in theatre school affected the participants; and an immanent curriculum can be understood by theatrical engagement. In addition to exploring the interview data and monologues, time is spent understanding the works of Antonin Artaud, a prolific theatre artist and a/r/tography, a method of arts-based research. This theoretical and a/r/tographical investigation leads to the creation of Interludes. These Interludes, theorized as rhizomatic curricular offshoots, allow for multiple entry points into the new understandings.
High-Mass, Four-Planet Models for HR 8799: Constraining the Orbital Inclination and Age of the System

description: Debates regarding the age and inclination of the planetary system orbiting HR 8799, and the release of additional astrometric data following the discovery of the fourth planet prompted us to examine the possibility of constraining these two quantities by studying the long-term stability of this system at different orbital inclinations and in its high-mass configuration (7-10-10-10 MJup). We carried out ~1.5 million N-body integrations for different combinations of orbital elements of the four planets. The most dynamically stable combinations survived less than ~5 Myr at inclinations of 0° and 13°, and 41, 46, and 31 Myr at 18°, 23°, and 30°, respectively. Given such short lifetimes and the location of the system on the age-luminosity diagram for low-mass objects, the most reasonable conclusion of our study is that the planetary masses are less than 7-10-10-10 MJup and the system is quite young. Two trends to note from our work are as follows. (1) In the most stable systems, the higher the inclination, the more the coordinates for planets b and c diverge from the oldest archival astrometric data (released after we completed our N-body integrations), suggesting that either these planets are in eccentric orbits or have lower orbital inclinations than that of planet d. (2) The most stable systems place planet e closer to the central star than is observed, supporting the conclusion that the planets are more massive and the system is young. We present the details of our simulations and discuss the implications of the results.

A rather uncommon East African species, with a general distribution from south-eastern Kenya to north-eastern parts of South Africa. All shells found at all three stations on Cabo Delgado are slightly smaller than the type of this species. Differs from all other snails in the area by the small, elongated shell with a weak parietal tooth and slight palatal thickening.

description: The exclusive queueing process (EQP) has recently been introduced as a model for the dynamics of queues which takes into account the spatial structure of the queue. It can be interpreted as a totally asymmetric exclusion process of varying length. Here we investigate the case of deterministic bulk hopping p=1 which turns out to be one of the rare cases where exact nontrivial results for the dynamical properties can be obtained. Using a time-dependent matrix product form we calculate several dynamical properties, e.g. the density profile of the system.

description: Flexibility and reconfigurability regarding mass-customized products are the key premises of future industrialization. The amalgamation of Digital Twin (DT) approaches, knowledge-representing technologies, and skill-based engineering methodologies allow such approaches to emerge. This paper deals with the integration of knowledge representations as a driver for holistic system intelligence ranging from physical assets to the Internet of Digital Twins (IoDT) within the Digital Twin Reference Model (DTRM). This is what it takes to spur DTs to intelligence and proactive collaboration behaviors. Despite the domain-agnostic, universal applicability of the concept, exemplary implementation approaches from the field of production and intralogistics illustrate the feasibility. Specific domain knowledge can be dynamically aggregated and used as a basis for negotiation scenarios between DTs.

description: The Higgs low-energy theorem gives a simple and elegant way to estimate the couplings of the Higgs boson to massless gluons and photons induced by loops of heavy particles. We extend this theorem to take into account possible nonlinear Higgs interactions resulting from a strong dynamics at the origin of the breaking of the electroweak symmetry. We show that, while it approximates with an accuracy of order a few percents single Higgs production, it receives corrections of order 50% for double Higgs production. A full one-loop computation of the gg->hh cross section is explicitly performed in MCHM5, the minimal composite Higgs model based on the SO(5)/SO(4) coset with the Standard Model fermions embedded into the fundamental representation of SO(5). In particular we take into account the contributions of all fermionic resonances, which give sizeable (negative) corrections to the result obtained considering only the Higgs nonlinearities. Constraints from electroweak precision and flavor data on the top partners are analyzed in detail, as well as direct searches at the LHC for these new fermions called to play a crucial role in the electroweak symmetry breaking dynamics.

description: Membrane proteins play vital roles in cells and have pharmacological significance. Cryo-EM and improved membrane mimetic systems have advanced the study of membrane proteins. Styrene/maleic acid and diisobutylene/maleic acid copolymers solubilize membrane proteins, forming nanodiscs that mimic native membranes. The structure of the formate channel A in detergent micelles was resolved by cryo-EM, revealing pore characteristics. Detergents can affect protein structure and function. Amphiphilic copolymers, particularly Sulfo-DIBMA, solubilized artificial vesicles and native membranes from Chaetomium thermophilum, enabling protein identification and 3D reconstruction. Myo-inositol-1-phosphate and an unidentified nanodisc-embedded protein were characterized. A potential potassium channel candidate was identified. This research demonstrates the efficient solubilization of membranes using functionalized copolymers, providing insights for structure-based drug development

Physiological effects of trading fatty acids between organellar membranes in salt-treated Arabidopsis seedlings

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2023
Subjects: subject: 572

description: Rapid and efficient physiological responses, such as membrane lipid adjustments, are important plant responses to maintain membrane integrity. The distribution of lipid intermediates between cell membranes is thought to be globally coordinated. Salt stress-induced changes in lipid abundance were observed after treatment of Arabidopsis seedlings for 2 h for both the extraplastidal lipid phosphatidylcholine (PC) and plastidal lipid monogalactosyldiacylglycerol (MGDG). The exchange and compensation of fatty acids between plastids and ER is known from fatty acid biosynthesis and studies of fatty acid desaturase mutants. Examination of the fad3 mutant revealed lipid patterns similar to salt-stressed WT seedlings and no further salt stress-induced lipid changes. Presumably, increased MGDG abundance resulted in changes in photosynthetic performance in salt-stressed plants and NPQ in the fad3 mutant.
description: Schnelle und effiziente physiologische Reaktionen, wie die Anpassung von Membranlipiden sind wichtige Reaktionen der Pflanzen, um die Membranintegrität zu erhalten. Es wird vermutet, dass die Verteilung von Lipid-Intermediaten zwischen den Zellmembranen global koordiniert wird. Salzstressinduzierte Veränderungen der Lipidabundanz konnten nach der Behandlung von Arabidopsis Keimlingen für 2 h sowohl für das extraplastidären Lipid PC als auch plastidären Lipid MGDG beobachtet werden. Der Austausch und die Kompensation von Fettsäuren zwischen Plastiden und ER ist aus der Fettsäurebiosynthese und Untersuchung der Fettsäuredesaturase Mutanten bekannt. Die Untersuchung der fad3 Mutante zeigte ähnliche Lipidmuster wie salzgestresste WT Keimlinge und keinen weiteren Saltstress induzierten Lipidveränderungen. Vermutlich führte die erhöhte MGDG Abundanz zu einer Veränderung der photosynthese Leistung in salzstressten Pflanzen und des NPQs in der fad3 Mutante.
Bayesian analysis of the astrobiological implications of life's early emergence on Earth

description: Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface. The early emergence of life on Earth has been taken as evidence that the probability of abiogenesis is high, if starting from young-Earth-like conditions. We revisit this argument quantitatively in a Bayesian statistical framework. By constructing a simple model of the probability of abiogenesis, we calculate a Bayesian estimate of its posterior probability, given the data that life emerged fairly early in Earth's history and that, billions of years later, curious creatures noted this fact and considered its implications. We find that, given only this very limited empirical information, the choice of Bayesian prior for the abiogenesis probability parameter has a dominant influence on the computed posterior probability. Although terrestrial life's early emergence provides evidence that life might be common in the Universe if early-Earth-like conditions are, the evidence is inconclusive and indeed is consistent with an arbitrarily low intrinsic probability of abiogenesis for plausible uninformative priors. Finding a single case of life arising independently of our lineage (on Earth, elsewhere in the Solar System, or on an extrasolar planet) would provide much stronger evidence that abiogenesis is not extremely rare in the Universe.

description: The temporal evolution of a dilute granular gas, both in a compressible flow (uniform longitudinal flow) and in an incompressible flow (uniform shear flow), is investigated by means of the direct simulation Monte Carlo method to solve the Boltzmann equation. Emphasis is laid on the identification of a first "kinetic" stage (where the physical properties are strongly dependent on the initial state) subsequently followed by an unsteady "hydrodynamic" stage (where the momentum fluxes are well-defined non-Newtonian functions of the rate of strain). The simulation data are seen to support this two-stage scenario. Furthermore, the rheological functions obtained from simulation are well described by an approximate analytical solution of a model kinetic equation.

Exploring the status of science outreach in science teaching
Creators: name: Friedman, Romy
Publisher: name: University of British Columbia
Year: 2012

description: Despite the continued demonstration of the importance of science outreach programs to inspire student interest and motivation in science, my experience is that the science outreach programs are currently underutilized in schools. This is besides the fact that many stakeholders including students, teachers, parents, scientists, the community and society can potentially benefit from science outreach programs. With most studies focusing on assessing the impact of outreach on students, there remains a gap in research on the processes that are undertaken by teachers and outreach providers to create these opportunities. This mixed-methods study used scientist-in-residence outreach model, as reference because of its prominence in promoting science outreach in attempt to address this gap by investigating teachers’ science outreach practices in schools to better understand the decisions they make about the place or status of science outreach programs, in their teaching. The study objectives were to (1) investigate the science outreach practices of science teachers, focusing on how outreach is integrated into curricular and instructional practices; (2) explore how teachers and outreach providers implement various science outreach models, including any potential challenges to this; (3) propose a model that better utilizes the efforts of both these stakeholders, teachers and outreach providers, with the aim of improved communication, that both teachers and outreach providers can use to inspire student interest and motivation in science. This study took a mixed methods approach, using a quantitative survey-questionnaire and qualitative interviews to elicit information on the practices of both elementary and secondary teachers regarding various forms of science outreach. Interviews occur with teachers, scientists, and other members of non-profit organizations coordinating various science outreach programs. Organizations that use the scientists-in-residence outreach model were of particular interest. Analysis of the data corpus revealed engagement, access, costs and comfort with science as the challenges for implementing outreach programs. Moreover, attitude, delivery and use of a facilitator were determined as ways to overcome these challenges. Based on these insights an emergent model is proposed to assist both teachers and outreach providers in inspiring student interest and motivation in science through outreach programs.
Categorical Tinkertoys for N=2 Gauge Theories

description: In view of classification of the quiver 4d N=2 supersymmetric gauge theories, we discuss the characterization of the quivers with superpotential (Q,W) associated to a N=2 QFT which, in some corner of its parameter space, looks like a gauge theory with gauge group G. The basic idea is that the Abelian category rep(Q,W) of (finite-dimensional) representations of the Jacobian algebra $\mathbb{C} Q/(\partial W)$ should enjoy what we call the Ringel property of type G; in particular, rep(Q,W) should contain a universal `generic' subcategory, which depends only on the gauge group G, capturing the universality of the gauge sector. There is a family of 'light' subcategories $\mathscr{L}_λ\subset rep(Q,W)$, indexed by points $λ\in N$, where $N$ is a projective variety whose irreducible components are copies of $\mathbb{P}^1$ in one--to--one correspondence with the simple factors of G. In particular, for a Gaiotto theory there is one such family of subcategories, $\mathscr{L}_{λ\in N}$, for each maximal degeneration of the corresponding surface $Σ$, and the index variety $N$ may be identified with the degenerate Gaiotto surface itself: generic light subcategories correspond to cylinders, while closed-point subcategories to `fixtures' (spheres with three punctures of various kinds) and higher-order generalizations. The rules for `gluing' categories are more general that the geometric gluing of surfaces, allowing for a few additional exceptional N=2 theories which are not of the Gaiotto class.

description: Verbesserte Überlebenschancen von Darmkrebspatient*innen bedingen häufiger chronische Krankheitsverläufe, was zu veränderten Versorgungsanforderungen führt. Defizite zeigen sich beim sektorenübergreifenden Therapiemanagement, wodurch vor allem in ländlichen Gebieten die poststationäre Versorgung gefährdet ist. Da auch in Sachsen-Anhalt die kleinräumige Gesundheitsversorgung als disparat gilt, war es das Ziel der Arbeit, anhand von GKV-Routinedaten die Versorgungssituation von Darmkrebspatient*innen zu analysieren. Unterschiede zwischen städtischen und ländlichen Regionen zeigten sich bei der Inanspruchnahme von Darmkrebszentren und ambulanten Ärzt*innen. Zudem wurde eine Unterversorgung mit (neo)adjuvanten Therapien deutlich. Versicherte aus der Großstadt wiesen ein besseres Gesamtüberleben auf als Versicherten aus ländlichen Regionen. Es bedarf einer Optimierung der Versorgungsstrukturen und -prozesse, die eine frühe Diagnose und barrierefreie Inanspruchnahme adäquater Therapien ermöglicht.
description: Improved survival rates of patients with colorectal cancer are attended to changed care requirements due to chronic courses of the disease. Deficits are evident in cross-sectoral management, which jeopardizes ambulatory care after the hospital stay, especially in rural areas. Since the small-scale healthcare in Saxony-Anhalt is also considered disparate, this study aims to analyze colorectal cancer care based on routine data from a public health insurer. Differences between urban and rural regions were evident in the use of certified hospitals and out-patient treatment. In addition, an undersupply of adjuvant or neoadjuvant treatment became apparent. Overall survival was significantly higher in patients living in urban vs rural regions.

description: Interpreters in lawful interception of communications are an almost invisible group of language professionals. They participate in secret surveillance measures and enable law enforcement authorities to intercept conversations held in a foreign language. This group of translational agents who perform a hybrid activity between interpreting and translation within an institutional legal context has received scant attention from either translation and interpreting or legal studies. If the topic is addressed at all, it is most often examined within the context of police interpreting, even though intercept interpreters do not participate in the kind of triadic communication situation typical of face-to-face interpreting. Moreover, the sensitive context makes it difficult to collect data on the topic. In this article, we analyse nine judgments rendered by the Swiss Federal Supreme Court (FSC) from 2002 to 2019 concerning lawful interception with interpreters. Higher courts not only dispense justice but also contribute to the continued development of the law. Their judgments are also a rich source of knowledge, providing rare information about an understudied research area. These judgments are crucial because, as we will argue, it is the legal order and its implementation through jurisprudence that shape the degree of (in-)visibility of intercept interpreters. In addition, these judgments provide valuable information about the working processes and professional context of intercept interpreters. Our qualitative content analysis reveals that the FSC explicitly demands the visibility of intercept interpreters and their activity in some cases while implicitly accepting or deliberately generating their invisibility in others.

description: Die Arbeit erschließt anhand einer großen Anzahl von Sitzungsberichten und Abhandlungen den wissenschaftlichen Kontext, in dem geometrische Anschauungsmodelle durch deutsche Gelehrte während der Jahre 1860–1877 hergestellt und verwendet worden sind. Nach einer Einführung zur Geschichte des mathematischen Modellbaus im Langen 19. Jahrhundert, folgen drei Studien zur wissenschaftlichen Verwendung von Modellen in (1.) Ernst Kummers Arbeiten zur geometrischen Optik, (2.) Julius Plückers und Felix Kleins Untersuchungen quadratischer Linienkomplexe und Komplexflächen sowie (3.) der Klassifikation kubischer Flächen durch Ludwig Schläfli und Karl Rodenberg. Für viele Entwürfe wird eine detaillierte Beschreibung gegeben. In den letzten beiden Kapiteln werden die wissenschaftliche Bedeutung des Modellbaus und die historischen Wechselbeziehungen dieser Praxis zur Geschichte der Geometrie während des 19. Jahrhunderts untersucht.
description: Based on a large number of reports of scientific meetings and papers, the thesis opens up the research context in which geometric models were produced and used by German scholars during the years 1860-1877. At the beginning, an introduction to the history of mathematical model making in the long 19th century is given. This is followed by three studies on the scientific use of models in (1.) Ernst Kummer's work on geometrical optics, (2.) Julius Plücker's and Felix Klein's investigations of quadratic line complexes and complex surfaces, and (3.) the classification of cubic surfaces by Ludwig Schläfli and Karl Rodenberg. Many designs are described in detail. The last two chapters examine the scientific significance of model making and the historical interrelations of this practice with the history of geometry during the 19th century

description: After a brief introduction to the theoretical basis of the Higgs mechanism for generating the masses of elementary particles, the experimental searches for Higgs particles will be summarized, from bounds at LEP to inferences for LHC. The report will focus on the Standard Model, though some central results on extended Higgs systems, as conjectured for example in supersymmetric theories, will also be recapitulated. Alternative scenarios based on spontaneous symmetry breaking by novel strong interactions are adumbrated at the theoretical level.

 Macrochlamys minima: Adams 1867: 303, pl. 19, fig. 2 (near Port Louis, Mauritius; c. 1.3× 0.5 mm).
 A single shell was found on Cabo Delgado.Previously known only from the Mascarene Islands where it is quite common and recently recorded from Zanzibar (Rowson et al. in press). The smallest species in the study area. Can be easily distinguished from the following species by the lack of spiral sculpture.
 The shell was originally described “... depressa, discoidea... Diam. 1⅓, alt. ½ mill.” and the apex is not visible on the original illustration. The measurements in the original description were clearly approximate. Griffiths and Florens (2006: 130, pl. 27, fig. E) illustrated M. minima with a protruding apex and gave “Diameter: 1.3 mm; height 0.5 mm ” for the size of the shell. However, if calculated from the proportions of that illustration, assuming that diameter is 1.3 mm, the height of the shell would be 0.82 mm. Thus, in view of the fact that there are no other shells with a narrow umbilicus, without any spiral sculpture and 1.3 mm in diameter found so far on Mauritius, it would be safe to assume that M. minima has variably protruding apical whorls.

description: The nature of solar wind (SW) turbulence below the proton gyroscale is a topic that is being investigated extensively nowadays. Although recent observations gave evidence of the dominance of Kinetic Alfvén Waves (KAW) at sub-ion scales with $ωω_{ci}$) is more relevant. Here, we propose to study key properties of the short wavelength plasma modes under realistic SW conditions, typically $β_i\gtrsim β_e\sim 1$ and for high oblique angles of propagation $80^\circ\leq Θ_{\bf kB}<90^\circ$ as observed from the Cluster data. The linear properties of the plasma modes under these conditions are poorly known, which contrasts with the well-documented cold plasma limit and/or moderate oblique angles of propagation ($Θ_{\bf kB} <80^\circ$). Based on linear solutions of the Vlasov kinetic theory, we discuss the relevance of each plasma mode (fast, Bernstein, KAW, whistler) in carrying the energy cascade down to electron scales. We show, in particular, that the shear Alfvén mode extends at scales $kρ_i\gtrsim1$ following either a whistler mode ($ω>ω_{ci}$) or a KAW mode (with $ω
