description: Monoclonal antibodies (mAbs) are of great interest to the biopharmaceutical industry due to their widely used application as human therapeutic and diagnostic agents. As such, mAb require to exhibit human-like glycolization patterns. Therefore, recombinant Chinese hamster ovary (CHO) cells are the favored production organisms; many relevant biopharmaceuticals are already produced by this cell type. To optimize the mAb yield in CHO DG44 cells a corelation between stress-induced cell size expansion and increased specific productivity was investigated. CO2 and macronutrient supply of the cells during a 12-day fed-batch cultivation process were tested as stress factors. Shake flasks (500 mL) and a small-scale bioreactor system (15 mL) were used for the cultivation experiments and compared in terms of their effect on cell diameter, integral viable cell concentration (IVCC), and cell-specific productivity. The achieved stress-induced increase in cell-specific productivity of up to 94.94.9%–134.4% correlates to a cell diameter shift of up to 7.34 μm. The highest final product titer of 4 g/L was reached by glucose oversupply during the batch phase of the process.

description: Additive manufacturing (3D printing) enables the fabrication of highly customized and complex devices and is therefore increasingly used in the field of life sciences and biotechnology. However, the application of 3D-printed parts in these fields requires not only their biocompatibility but also their sterility. The most common method for sterilizing 3D-printed parts is heat steam sterilization—but most commercially available 3D printing materials cannot withstand high temperatures. In this study, a novel heat-resistant polyacrylate material for high-resolution 3D Multijet printing was evaluated for the first time for its resistance to heat steam sterilization and in vitro biocompatibility with mouse fibroblasts (L929), human embryonic kidney cells (HEK 293E), and yeast (Saccharomyces cerevisiae (S. cerevisiae)). Analysis of the growth and viability of L929 cells and the growth of S. cerevisiae confirmed that the extraction media obtained from 3D-printed parts had no negative effect on the aforementioned cell types, while, in contrast, viability and growth of HEK 293E cells were affected. No different effects of the material on the cells were found when comparing heat steam sterilization and disinfection with ethanol (70%, v/v). In principle, the investigated material shows great potential for high-resolution 3D printing of novel cell culture systems that are highly complex in design, customized and easily sterilizable—however, the biocompatibility of the material for other cell types needs to be re-evaluated.

description: Editors' Note: As a result of the recent federal welfare reform legislation, welfare recipients are being forced to find jobs. At the same time, the strong growth of the economy is leaving many Americans behind. Planners need to consider new ways to connect unemployed and underemployed people to jobs. The editors of Carolina Planning hosted a forum to discuss how people in North Carolina are dealing with these issues. We brought together a panel that includes varied perspectives, from private training programs to community development corporations to state agencies. The text of this article is an edited version of the discussion, which took place at the University of North Carolina-Chapel Hill on November 10, 1997.

description: Integrating optical sensors and 3D-printed optics into single-use (SU) cultivation vessels for customized, tailor-made equipment could be a next big step in the bioreactor and screening platform development enabling online bioprocess monitoring. Many different parameters such as pH, oxygen, carbon dioxide and optical density (OD) can be monitored more easily using online measuring instruments compared to offline sampling. Space-saving integrated sensors in combination with adapted optics such as prisms open up vastly new possibilities to precisely guide light through SU vessels. This study examines how optical prisms can be 3D-printed with a 3D-inkjet printer, modified and then evaluated in a custom made optical bench. The prisms are coated or bonded with thin cover glasses. For the examination of reflectance performance and conformity prisms are compared on the basis of measured characteristics of a conventional glass prism. In addition, the most efficient and reproducible prism geometry and modification technique is applied to a customized 3D-printed cultivation vessel. The vessel is evaluated on a commercial sensor-platform, a shake flask reader (SFR) vario, to investigate its sensing-characteristics while monitoring scattered light with the turbidity standard formazine and a cell suspension of Saccharomyces cerevisiae as model organism. It is demonstrated that 3D-printed prisms can be used in combination with commercial scattered light sensor-platforms to determine OD of a microbial culture and that a 3D-printed unibody design with integrated optics in a cultivation vessel is feasible. In the range of OD600 0–1.16 rel.AU a linear correlation between sensor amplitude and offline determined OD can be achieved. Thus, enabling for the first time a measurement of low cell densities with the SFR vario platform. Moreover, sensitivity is also at least three times higher compared to the commonly used method.
Search for ν_τ interactions with the nuclear emulsion films of the OPERA experiment

description: The OPERA experiment aims at measuring the ν_μ -> ν_τ oscillation through the ν_τ appearance in an almost pure ν_μ beam (CNGS). For the direct identification of the short-lived τ lepton, produced in ν_τ CC interactions, a micrometric detection resolution is needed. Therefore the OPERA detector makes use of nuclear emulsion films, the highest spatial resolution tracking device, combined with lead plates in an emulsion cloud chamber (ECC) structure called 'brick'. In this paper the nuclear emulsion analysis chain is reported; the strategy and the algorithms set up will be described together with their performances.

description: In a scattering experiment, the induced dipole moments of a magnetoelectric point scatterer in response to driving fields are given by its polarizability tensor α. Its linewidth will be dictated by the local density of optical states (LDOS) at the scatterer's position. To retrieve the magnetoelectric cross coupling components of αfor an archetypical magnetoelectric scatterer - a split ring resonator - we study the frequency dependent extinction cross section as a function of distance to an interface. Rather than following a purely electric or purely magnetic LDOS, we find a dependence which reflects the interplay of both dipole moments in a 'mixed' magnetoelectric LDOS. For a strongly magnetoelectric cross-coupled microwave scatterer, we compare analytical point dipole with finite element method calculations.

description: By means of simple models in a flat spacetime manifold we examine some of the issues that arise when quantizing interacting quantum fields in multi-metric backgrounds. In particular we investigate the maintenance of a causal structure in the models. In this context we introduce and explain the relevance of an interpolating metric that is a superposition of the individual metrics in the models. We study the renormalisation of a model with quartic interactions and elucidate the structure of the renormalisation group and its implications for Lorentz symmetry breakdown.

The Politics of City Building: Pro-Growth Planning Regimes And Equitable Distribution of Infrastructure
Creators: name: Crick, Jeffrey S.
name: Brock, Timothy J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Neoliberal governance and pro-growth planning regimes divide the urban form into small patches of private development. This division results in a fragmentation of infrastructure and an increase in socio-spatial inequalities. City planners and policymakers evaluate the value of urban infrastructure projects based on economic development potential, including anticipated economic revenues and return on investment. Because of this, infrastructure and service distribution become clustered in commercial districts, which have the greatest potential for economic growth. The authors critique the conventional economic evaluation criteria for infrastructure and services projects and highlight the infrastructural inequity that results from growth-oriented planning. This paper presents transit oriented development as an example of pro-growth planning and suggests new planning obligations and evaluation processes that incorporate the everyday uses of public infrastructure projects.
Essays in macroeconomics
Creators: name: Kim, Min
Publisher: name: No Publisher Supplied
Year: 2023

description: This dissertation is composed of three chapters that study topics in the fields of international macroeconomics and monetary economics. Chapter 1 examines the role of sterilized asset purchase programs in dealing with sudden stops. It develops a small-open economy DSGE model, shedding light on how and why the policy is able to dampen adverse effects from capital outflows. The policy gives rise to trade-offs between deep recession and slow recovery. The study provides the best policy design in regard to which asset to purchase and how to sterilize. Chapter 2 studies optimal foreign reserve management with and without commitment. It shows that the power of commitment helps address policy trade-offs arising from fear of floating and costs of reserve management. It also provides a sustainable plan that allows the government without commitment to achieve Ramsey outcome in equilibrium. Chapter 3 develops a new estimation method for potential GDP. The method computes the level of counterfactual output corresponding to potential GDP derived from a standard New Keynesian framework. By applying the method to US data, the study provides evidence in favor of the output hysteresis hypothesis. Overall, the dissertation provides important and practical policy implications for central bankers. The findings contribute to the ongoing debate on the monetary policymaking in academia as well as in policy circle.

description: Space fractional convection diffusion equation describes physical phenomena where particles or energy (or other physical quantities) are transferred inside a physical system due to two processes: convection and superdiffusion. In this paper, we discuss the practical alternating directions implicit method to solve the two-dimensional two-sided space fractional convection diffusion equation on a finite domain. We theoretically prove and numerically verify that the presented finite difference scheme is unconditionally von Neumann stable and second order convergent in both space and time directions.

SRO is rapidly heated by fs-laser pulses with 208 kHz repetition rate. Diffraction of x-ray pulses derived from a synchrotron measures the transient out-of-plane lattice constant c of all three materials simultaneously from 120 ps to 5 mus with a relative accuracy up to Delta c/c = 10^-6. The in-plane propagation of sound is essential for understanding the delayed out of plane expansion.

description: Magnetic field fluctuations arising from fundamental spins are ubiquitous in nanoscale biology, and are a rich source of information about the processes that generate them. However, the ability to detect the few spins involved without averaging over large ensembles has remained elusive. Here we demonstrate the detection of gadolinium spin labels in an artificial cell membrane under ambient conditions using a single-spin nanodiamond sensor. Changes in the spin relaxation time of the sensor located in the lipid bilayer were optically detected and found to be sensitive to near-individual proximal gadolinium atomic labels. The detection of such small numbers of spins in a model biological setting, with projected detection times of one second, opens a new pathway for in-situ nanoscale detection of dynamical processes in biology.

description: Chaining techniques show that if X is an isotropic log-concave random vector in R^n and Gamma is a standard Gaussian vector then E |X| < C n^{1/4} E |Gamma| for any norm |*|, where C is a universal constant. Using a completely different argument we establish a similar inequality relying on the thin-shell constant sigma_n = sup ((var|X|^){1/2} ; X isotropic and log-concave on R^n). In particular, we show that if the thin-shell conjecture sigma_n = O(1) holds, then n^{1/4} can be replaced by log (n) in the inequality. As a consequence, we obtain certain bounds for the mean-width, the dual mean-width and the isotropic constant of an isotropic convex body. In particular, we give an alternative proof of the fact that a positive answer to the thin-shell conjecture implies a positive answer to the slicing problem, up to a logarithmic factor.

description: As the use of engineered nanomaterials continues to grow, there is a pressing need to improve the safety and sustainability of these materials through the incorporation of safety-by-design (SbD) and safe- and sustainable-by-design (SSbD) principles. In this field, high-throughput, in-vitro screening methods are essential for evaluating toxicity and identifying potential hazards. In this presentation, we showcase two new technologies developed under the SABYDOMA project to accelerate the wear of engineered nanomaterials and perform high-throughput screening on nanomaterial leachate media. Combined, these technologies can form a powerful tool to aid the understanding of the toxic properties of nanomaterials at the point of leaching.

Asperuloside appears to be the second representative of the iridoid monoterpene group found in the plant family Asteraceae, which until recently was considered to lack iridoids.

description: We analyze the possible dynamical emergence of IR conformal field theory describing the low-energy excitations of near-extremal black holes in five-dimensional compactification of heterotic strings. We find that, by tuning the mass and charges in such a way that the extremal black holes have a classically vanishing horizon area, the near-horizon develops an AdS3 throat and when we combine the low-energy limit with vanishing Newton coupling constant, the system has a dual conformal field theory description. We compare our results with c-extremization and the Kerr/CFT predictions.

description: A turbulent cavity flow at Mach 1.5 and 2.5 is modelled to study the flow instability and the associated aerodynamic noise generation. The short-time averaged Navier- Stokes equations, coupled with a k − ω turbulence model, are solved to predict the large-scale time-dependent flow. Values of the cavity wall pressure, drag, streamwise velocity and density are in good in agreement with past measurements and the results of other computations. The noise generation physics of the unsteady flow is addressed by estimating the noise source strength in a Lighthill acoustic analogy. The time-dependent flow predictions highlighted the upstream and downstream cavity edges as areas of large flow unsteadiness. The same areas are identified by the acoustic analogy as the dominant noise source regions in this flow.

description: A small tuneable quantum ring with less than ten electrons was shown to exhibit Aharonov-Bohm oscillations as well as Coulomb blockade. At strong coupling to the leads, evidence of a Kondo effect induced by a single spin on the ring was obtained. Analysis of the phase evolution of the Aharonov-Bohm effect in the Kondo regime yielded phase jumps by π at the Coulomb-blockade resonances and a smooth shift of the Aharonov-Bohm maxima in between.

description: The Torrence Creek Stream Restoration project in Huntersville, North Carolina, is an example of how Mecklenburg County’s investment in improving its green infrastructure continues to yield environmental, community, and financial returns. This ecological restoration will improve riparian systems that have been damaged by decades of rapid growth. Upon its completion, the planned stream, wetland, and floodplain restoration project will restore more than 7,500 linear feet of the main stem of Torrence Creek starting at McCoy Road, and 9,000 linear feet of Torrence Creek Tributary #2, from Interstate-77 to Bradford Hill Lane (at the confluence with the Torrence Creek main stem). The planning, permitting, and design stages are complete. Construction began in February 2010 and will take approximately one year.

description: Ein mobiler Roboter benötigt ein Abbild seiner Umgebung, um eine autonome Navigation durchzuführen. Dieses Abbild, das sogenannte Umgebungsmodell, kann Objekte und Landmarken oder abstrakte Informationen beinhalten, wie topologische Beziehungen. Für diesen Zweck muss der Roboter mit seiner Sensorik sein Umfeld erfassen und die Sensordaten aufbereiten. Dabei stellen feste und flüssige Schwebeteilchen (Aerosole) für die mobile Robotik ein Problem dar. Zum Beispiel verdeckt aufgewirbelter Staub die Sicht für RGB-Kameras in der Agrar- und Bergbaurobotik, Rauch und Feuer beeinträchtigt die Messwerte von LiDAR-Scannern in der Search-and-Rescue-Robotik und schlechte Witterungsbedienungen (Regen, Schnee, Nebel) sind typische Probleme für autonome Straßenfahrzeuge. Dementsprechend liefern populäre Sensoren, wie LiDAR-Scanner, unter diesen Bedingungen nicht genügend brauchbare Messwerte, um die Kernkompetenzen eines autonom fahrenden Systems (Kartierung, Lokalisierung und Navigation) auszuführen. Daher ist die Integration von Sensortypen, die nicht von Aerosolen beeinträchtigt werden, erforderlich, um auch hier Umgebungsmodelle zu erstellen. In diesem Zusammenhang beschäftigt sich diese Arbeit mit dem Einsatz von Radar auf dem Gebiet der Kartierung und Lokalisierung. Zum einen werden neue Radarmessprinzipien zur Umgebungsmodellierung in der mobilen Robotik untersucht, zum anderen LiDAR-Radar-Fusionsverfahren vorgestellt. Durch die Fusionierung von Radar- und LiDAR-Messungen lassen sich besonders in Umgebungen mit wechselhaften Sichtbedingungen die Vorteile beider Sensoren kombinieren. Hierfür werden drei Fusionsverfahren und ein SLAM-Verfahren ausführlich beschrieben und evaluiert. Die dargestellten Fusionsverfahren ermöglichen es, Umgebungen zu kartieren, in denen sowohl LiDAR- als auch Radar-Scanner allein nicht erfolgreich wären. Mit der durch die fusionierten Daten ermittelten Konzentrationsgröße wird die Verteilung von Aerosolen beschrieben und parallel zu dem vorgestellten SLAM-Verfahren mit einem Finite-Differenzen-Modell in das Umgebungsmodell eingetragen.

description: We study the class of cooperative Boolean networks whose only regulatory functions are COPY, binary AND, and binary OR. We prove that for all sufficiently large N and c < 2 there exist Boolean networks in this class that have an attractor of length > c^N whose basin of attraction comprises an arbitrarily large fraction of the state space. The existence of such networks contrasts with results on various other types of dynamical systems that show nongenericity or absence of non-steady state attractors under the assumption of cooperativity.

Reauthorization of the Clean Water Act: The Dawn of Environmental Legislation under the Clinton Administration

description: An examination of the apparent leading bill before the United States Senate to reauthorize the Clean Water Act, entitled the "Water Pollution Prevention and Control Act of 1993", or Senate Bill 1114 (herein referred to as "S. 1114" or the "Bill"), reveals legislation consistent with many of the provisions of the Clean Air Act Amendments of 1990. The Clean Air Act Amendments appear to be viewed, at least by the authors of S. 1114, Senators Baucus (D-MT) and Chafee (R-RI), as a precedent for a number of approaches to environmental legislation. These precedents include an extremely detailed permitting program, concentration on the elimination of toxic constituents of discharges or emissions, pollution prevention, and a schedule of permit fees intended to shift the burden of funding the regulatory program to the regulated community and away from the taxpayer. S.1114 would impose on dischargers to surface waters (and indirect dischargers to publicly owned treatment works) many requirements to which permittees under the National Pollutant Discharge Elimination System (NPDES), established in the Federal Water Pollution Control Act amendments of 1972, were never subject. These new-generation regulatory devices include provisions for forcing technological advance in wastewater treatment without necessarily considering the economic impact on the industry, and prohibiting the use of certain substances in an industry's processes, irrespective of the industry's ability to treat and remove the substances from its effluent. There is a great deal of emphasis, directly or indirectly, on pollution prevention or source reduction of pollutants. Such an emphasis has led to the perception in the regulated community that this bill is far more intrusive into business decisions and process than its regulatory forebears. The Clean Air Act Amendments were a radical departure from the traditional means of industrial pollution control. Many of its more controversial provisions are now being tried out in S. 1114, for water, the other principal environmental medium for waste transport. What are the provisions which have regulated community observers standing up to take notice? This piece selects and summarizes several of the components of S. 1114 which would be sweeping in their effect on regulated industries. It proceeds through S. 1114, describes some of those sections which will have an significant effect on regulated industries, and explains the impact of the selected provisions.

description: A strong negative magnetoresistance is observed in a high-mobility two-dimensional electron gas in a GaAs/Al0.3Ga0.7As quantum well. We discuss that the negative magnetoresistance consists of a small peak induced by a combination of two types of disorder and a huge magnetoresistance explained by the interaction correction to the conductivity for mixed disorder. © 2013 AIP Publishing LLC.

description: To identify the synergistic action of differently prepared Ni-ZrO2 phase boundaries in methane dry reforming, we compared an “inverse” near-surface intermetallic NiZr catalyst precursor with the respective bulk-intermetallic NixZry material and a supported Ni-ZrO2 catalyst. In all three cases, stable and high methane dry reforming activity with enhanced anticoking properties can be assigned to the presence of extended Ni-ZrO2 phase boundaries, which result from in situ activation of the intermetallic Ni-Zr model catalyst systems under DRM conditions. All three catalysts operate bifunctionally; methane is essentially decomposed to carbon at the metallic Ni0 surface sites, whereas CO2 reacts to CO at reduced Zr centers induced by a spillover of carbon to the phase boundaries. On pure bulk Ni0, dissolved carbon accumulates in surface-near regions, leading to a sufficiently supersaturated state for completely surface-blocking graphitic carbon segregation. In strong contrast, surface-ZrO2 modified bulk Ni0 exhibits virtually the best decoking and carbon conversion conditions due to the presence of highly dispersed ZrO2 islands with a particularly large contribution of interfacial Ni0-ZrO2 sites and short C-diffusion pathways to the latter.

description: The shift towards electro mobility has a significant impact on the entire value chain of the automotive industry. The parallel production of Internal Combustion Engine, Battery Electric and Plug-in Hybrid Electric Vehicles con-fronts manufacturers with major challenges. This requires flexible production systems that are able to operate efficiently even under the influence of dynamic conditions. As could be seen in the COVID-19 pandemic, production systems must be able to react flexible and resilient even to these kinds of situations. Within the production system there is a multitude of temporally and spatially determined neuralgic points at which a reaction to dynamic conditions is possible and necessary. In order to make target-oriented decisions at these points, a large amount of data from many different sources is required as input parameters. The decisions can be made manually, semi-automatically or automatically by a human, a machine or a (software) system. Therefore it is essential that influences, input and output variables as well as decisions and the solution space are provided in a defined manner enabling all involved units to process the information. The paper therefore describes the first steps in modeling decisions for dynamic line-less assembly systems. Starting with an introduction to the topic and the multi-variant automotive production, the architecture of this kind of flexible assembly system is briefly described. Afterwards a description of the formal modeling of decisions in assembly systems is presented. Finally, after a discussion of the results, an outlook on the next steps and further research needs is given.
