Bio-Inspired Cell Sense-and-Respond Systems Through Bio-Synthetic and Robotics Approaches

subject: FOS: Mechanical engineering

description: Living systems have developed intricate multi-functional methods of sensing and responding to their surroundings at the cellular level at low spatial and energetic costs. Exploiting or mimicking these functionalities would have tremendous implications in both wearable devices, where both weight and power requirements are limiting factors, and drug delivery, where timed, localized release can have tremendous impact on drug efficacy. These goals can be achieved by either altering existing structures, such as modifying genetics in organisms to respond to stimuli, or by building synthetic lipid vesicle systems to mimic cellular morphologies. To the end of altering existing biological frameworks, we have genetically modified strains of Escherichia coli to function as chemical sensors within flexible, biomimetic systems. This approach expands the functionalities of soft machines at low cost to spatial and power considerations, two limiting factors to the development of these devices. By utilizing existing biological architecture and implementing modified organisms in flexible devices, we can produce high-functioning, low-energy wearable bio-sensors. Alternatively, we have also worked to replicate the mechanical sensing capabilities of cellular systems from a bottom-up direction, building a liposome-based system designed to sense mechanical deformation due to external forces. This device could be used as a localized drug release mechanism capable of responding to cues from outside of the body, as well as the framework for an artificial mechanotransduction system. To test this, we have developed a gut-on-a-chip framework in which to apply the magnetoliposomes for controlled rupture and localized drug delivery.

description: We theoretically analyse the efficiency of a quantum memory for single photons. The photons propagate along a transmission line and impinge on one of the mirrors of a high-finesse cavity. The quantum memory is constituted by a single atom within the optical resonator. Photon storage is realised by the controlled transfer of the photonic excitation into a metastable state of the atom and occurs via a Raman transition with a suitably tailored laser pulse, which drives the atom. Our study is supported by numerical simulations, in which we include the modes of the transmission line and we use the experimental parameters of existing experimental setups. It reproduces the results derived using input-output theory in the corresponding regime and can be extended to compute dynamics where the input-output formalism cannot be straightforwardly applied. Our analysis determines the maximal storage efficiency, namely, the maximal probability to store the photon in a stable atomic excitation, in the presence of spontaneous decay and cavity parasitic losses. It further delivers the form of the laser pulse that achieves the maximal efficiency by partially compensating parasitic losses. We numerically assess the conditions under which storage based on adiabatic dynamics is preferable to non-adiabatic pulses. Moreover, we systematically determine the shortest photon pulse that can be efficiently stored as a function of the system parameters.

description: The vacuum energy is calculated for a free, conformally-coupled scalar field on the orbifold space-time \R$\times §^2/Γ$ where $Γ$ is a finite subgroup of O(3) acting with fixed points. The energy vanishes when $Γ$ is composed of pure rotations but not otherwise. It is shown on general grounds that the same conclusion holds for all even-dimensional factored spheres and the vacuum energies are given as generalised Bernoulli functions (i.e. Todd polynomials). The relevant $ζ$- functions are analysed in some detail and several identities are incidentally derived. The general discussion is presented in terms of finite reflection groups.

description: Motivated by the question whether quantum gravity can "smear out" the classical singularity we analyze a certain quantum space and its quantum-mechanical completeness. Classical singularity is understood as a geodesic incompleteness, while quantum completeness requires a unique unitary time evolution for test fields propagating on an underlying background. Here the crucial point is that quantum completeness renders the Hamiltonian (or spatial part of the wave operator) to be essentially self-adjoint in order to generate a unique time evolution. We examine a model of quantum space which consists of a noncommutative BTZ black hole probed by a test scalar field. We show that the quantum gravity (noncommutative) effect is to enlarge the domain of BTZ parameters for which the relevant wave operator is essentially self-adjoint. This means that the corresponding quantum space is quantum complete for a larger range of BTZ parameters rendering the conclusion that in the quantum space one observes the effect of "smearing out" the singularity.

description: The systematic exploration of the application prospects of lotus stem fibers (LSFs) in natural composites is significantly important for the development of green, lightweight, functional biomass materials and products. In this study, the physical and chemical properties, micro/nano structures, micromechanical characteristics, cellulose crystallinity, and thermal stability of LSFs were systematically explored. The density, microstructure, and nanoindentation analyses revealed that the LSF is a lightweight natural fiber with a high modulus (11.2–11.7 GPa) and a good hardness (0.41–0.57 GPa). The transmission electron microscopy analysis indicated the existence of four types of sclerenchyma cells in a gradient distribution in the epidermis and exodermis of the LS. The chemical analysis, X-ray diffraction, and Fourier transform infrared spectroscopy indicated that the outer-layer LSFs have a high cellulose content (44.73%), high relative crystallinity index (49.2%) of cellulose, and small cellulose crystallite size (2.2 nm). As a result, these LSFs possess good mechanical properties.

description: This is the second paper of our series of works of studying the effects of active galactic nuclei (AGN) feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional high-resolution hydrodynamical numerical simulations. In these simulations, the inner boundary is chosen so that the Bondi radius is resolved. Physical processes like star formation, SNe Ia and II are taken into account. Compared to previous works, the main improvements is that we adopt the most updated AGN physics, which is described in detail in the first paper of this series (Yuan et al. 2018, Paper I). These improvements include the discrimination of the two accretion modes of the central AGN and the most updated descriptions of the wind and radiation in the two modes. In Paper I, we consider the case that the specific angular momentum of the gas in the galaxy is very low. In this paper, we consider the case that the specific angular momentum of the gas is high. In the galactic scale, we adopt the gravitational torques raised due to non-axisymmetric structure in the galaxy as the mechanism of the transfer of angular momentum of gas, as proposed in some recent works. Since our simulations are axisymmetric, we make use of a parameterized prescription to mimic this mechanism. Same as Paper I, we investigate the AGN light curve, typical AGN lifetime, growth of the black hole mass, AGN duty-cycle, star formation, and the X-ray surface brightness of the galaxy. Special attention is paid to the effects of specific angular momentum of the galaxy on these properties. We find that some results are qualitatively similar to those shown in Paper I, while some results such as star formation and black hole growth do show a significant difference due to the mass concentration in the galactic disk as a consequence of galactic rotation.

description: We report on the observation of a strain-induced insulator state in ferromagnetic La_0.7Sr_0.3CoO_3 films. Tensile strain above 1% is found to enhance the resistivity by several orders of magnitude. Reversible strain of 0.15% applied using a piezoelectric substrate triggers huge resistance modulations, including a change by a factor of 10 in the paramagnetic regime at 300 K. However, below the ferromagnetic ordering temperature, the magnetization data indicate weak dependence on strain for the spin state of the Co ions. We interpret the changes observed in the transport properties in terms of a strain-induced splitting of the Co e_g levels and reduced double exchange, combined with a percolation-type conduction in an electronic cluster state.

description: A notion of identity is of vital importance to each individual and the society. Its significance is manifest from two perspectives. On one hand, many systems rely on identity to provide proper services and fulfill their functionality. On the other hand, loss or leakage of identity can cause disastrous consequences. Identity is hence the sought-after to both benign and malicious entities. The representation, acquisition, validation and application of identity have been evolving consistently with the advances in technology. The last decade has witnessed the rapid adoption of mobile electronic devices and the emergence of Internet-of-Things hardware. Their onboard solid-state sensors enable ubiquitous sensing of user, environment and the interaction between them, accumulating ample sensory data that can be leveraged for user identification. In this dissertation, we study behavior-based user identification through passive sensing and its application in new real-world scenarios. We apply statistical modeling methods to the sensory measurements and extract sufficient entropy to establish user identity. A corresponding behavior-based identification framework is specified with necessary components and steps. We contrast the behavior-based approach to existing mechanisms and highlight its advantages. To demonstrate the practical implications of the proposed approach, we propose two application scenarios in the mobile and IoT realms, and conduct experiments. The mobile application investigates user recognition across mobile devices. We leverage the way users interact with mobile apps to track them even when they switch between multiple mobile devices. The IoT application, following the emergence of IoTequipped buildings, studies room-level indoor localization. We model residents’ mobility patterns through occupancy measurements and further learn their locations. Our experimental results demonstrate the effectiveness of identifying users through behavioral patterns under distinct application scenarios.

description: We apply deep neural networks (DNN) to data from the EXO-200 experiment. In the studied cases, the DNN is able to reconstruct the relevant parameters - total energy and position - directly from raw digitized waveforms, with minimal exceptions. For the first time, the developed algorithms are evaluated on real detector calibration data. The accuracy of reconstruction either reaches or exceeds what was achieved by the conventional approaches developed by EXO-200 over the course of the experiment. Most existing DNN approaches to event reconstruction and classification in particle physics are trained on Monte Carlo simulated events. Such algorithms are inherently limited by the accuracy of the simulation. We describe a unique approach that, in an experiment such as EXO-200, allows to successfully perform certain reconstruction and analysis tasks by training the network on waveforms from experimental data, either reducing or eliminating the reliance on the Monte Carlo.

Behavioral Modeling of Botnet Populations Viewed through Internet Protocol Address Space

Year: 2012
Subjects: subject: Probability
subject: Statistics
subject: FOS: Mathematics

description: A botnet is a collection of computers infected by a shared set of malicious software, that maintain communications to a single human administrator or small organized group. Botnets are indirectly observable populations; cyber-analysts often measure a botnet’s threat in terms of its size, but size is derived from a count of the observable network touchpoints through which infected machines communicate. Activity is often a count of packets or connection attempts, representing logins to command and control servers, spam messages sent, peer-to-peer communications, or other discrete network behavior. Front line analysts use sandbox testing of a botnet’s malicious software to discover signatures for detecting an infected computer and shutting it down, but there is less focus on modeling the botnet population as a collection of machines obscured by the kaleidoscope view of Internet Protocol (IP) address space. This research presents a Bayesian model for generic modeling of a botnet due to its observable activity across a network. A generation-allocation model is proposed, that separates observable network activity at time t into the counts yt generated by the malicious software, and the network’s allocation of these counts among available IP addresses. As a first step, the framework outlines how to develop a directly observable behavioral model informed by sandbox tests and day-to-day user activity, and then how to use this model as a basis for population estimation in settings using proxies or Network Address Translation (NAT) in which only the aggregate sum of all machine activity is observed. The model is explored via a case study using the Conficker-C botnet that emerged in March of 2009.

description: By modifying and extending recent ideas [C. Seoanez et al., Europhys. Lett. 78, 60002 (2007)], a theoretical framework to describe dissipation processes in the surfaces of vibrating micro- and nanoelectromechanical devices, thought to be the main source of friction at low temperatures, is presented. Quality factors as well as frequency shifts of flexural and torsional modes in doubly clamped beams and cantilevers are given, showing the scaling with dimensions, temperature, and other relevant parameters of these systems. Full agreement with experimental observations is not obtained, leading to a discussion of limitations and possible modifications of the scheme to reach a quantitative fitting to experiments. For nanoelectromechanical systems covered with metallic electrodes, the friction due to electrostatic interaction between the flowing electrons and static charges in the device and substrate is also studied.

description: Has any progress been made on understanding and predicting the 13 parameters which describe the observed masses and mixing angles of the quarks and leptons? Arguments are given in favor of pursuing schemes in which grand unified and family symmetries provide many relations among these 13 parameters. A sequence of simple assumptions leads to a supersymmetric SO(10) theory with 8 predictions: $\tan β, m_t, V_{cb}, m_s, m_s/m_d$, $m_u/m_d, V_{ub}$ and the amount of CP violation $J$. These predictions are presented, together with experiments which will test them.

description: We observe that the ratio of determinants of $2d$ Laplacians which appear in the duality transformation relating two sigma models with abelian isometries can be represented as a torsion of an elliptic (DeRham) complex. As a result, this ratio can be computed exactly and is given by the exponential of a local functional of $2d$ metric and target space metric. In this way the well known dilaton shift under duality is reproduced. We also present the exact computation of the determinant which appears in the duality transformation in the path integral.

description: The University of Houston (UH) Libraries, in partnership and consultation with numerous institutions, was awarded an IMLS National Leadership/Project Grant to support the creation of the Bridge2Hyku (B2H) Toolkit. Contents migration from proprietary systems to open source repositories remains a barrier for many institutions due to lack of tools, tutorials, and documentation. The B2H Toolkit, which includes migration strategies and use cases as well as tools for transitioning from CONTENTdm to Hyku, acts as a comprehensive resource to facilitate the repository migration process. This presentation will start with background information on the ecosystems, workflows, and tools, collectively known as the Bayou City Digital Asset Management System (BCDAMS), implemented at the UH Libraries. The presenters will then move to the key phases that make up the IMLS funded B2H Toolkit project plan. The presenters will also discuss how the project engages and strengthens the open source Samvera Community (formerly Hydra Community) around Hyku by leveraging our collective expertise through strategic collaboration. They will finally discuss sustainability and promotion of the B2H toolkit.

Becomming the Federal Reserve Chairman: The Micro-Discursive Construction of Administrative Authority as a Rhetorical Appeal To Ethos
Creators: name: Klein, Ari Z.
Publisher: name: Carnegie Mellon University
Year: 2016
Subjects: subject: 200302 English Language
subject: FOS: Languages and literature

description: In this dissertation, I explore the role that discourse plays in constructing the authoritative ethos by which we recognize actors who occupy positions to make decisions for society. Perhaps this administrative authority (Walton, 1997), or institutional power, has been conceptualized as a non-artistic influence on ethos—it is used, rather than invented (Kennedy, 2007, p. 39; Gottweis, 2007, p. 246; Cochran & Malone, 2009, p. 11)—because how an actor discursively constructs it as a rhetorical appeal might not be analytically obvious. Considering, however, that artistic (i.e., discourse-based) influences on ethos might be more effective if they emerge implicitly because a speaker‟s explicit self-evaluation can have an unfavorable impression on an audience (Perelman & Olbrecths Tyteca, 1969, p. 319; Amossy, 2001, p. 8; Scopelliti et al., 2015), methodologically, we need to probe the surfaces of texts in order to uncover a speaker‟s “hidden” rhetorical appeals to ethos. Following Cheng (2012) and Oddo (2014), I take a micro-discursive approach in order to move beyond the more obvious rhetorical features of ethos for a deeper understanding of how discourse latently carries out an ethotic function. As a case study, I draw upon the framework of register analysis (Biber, 1988) to examine the extent to which the office of power of the Chairman of the Federal Reserve is associated with a relatively stable set of micro-linguistic features. I analyze 142 public Federal Reserve speeches: 53 by Chairman Alan Greenspan (2002-2005), 42 by Governor Ben Bernanke (2002-2005), and 47 by Chairman Ben Bernanke (2006-2007). I argue that, in becoming the Chairman, Bernanke began repeating micro-linguistic choices that were significantly different than those that he had frequently drawn upon as a Governor (while serving under Chairman Greenspan) and, moreover, that resembled those that Greenspan had frequently made as the Chairman. In short, I argue that the Chairman speaks as the Chairman. My dissertation suggests that the register variation across the Federal Reserve‟s members implicitly rationalizes the Chairman-dictated, group “consensus” on policy decisions, through which the Fed inspires confidence with the public (Shapin, 1995, p. 270; Habermas, 2002, p. 96; Blinder, 2007, p. 114), by discursively co-constructing his ethos of administrative authority.

description: Abstract 

THE BACKGROUND OF THE STUDY 

The study's historical context was Anytime a worker comes into touch with a sharp object, they run the risk of suffering a sharp injury. Needles and other sharp medical devices (such as scalpels, blades, and scissors) that inadvertently pierce or cut the skin can result in sharps and needle stick injuries. Although little skin cuts from sharps and needles may not seem serious, the consequences can be more severe. These instruments have the potential to become infected since they come into contact with bodily fluids like blood.

METHODS

The study was a  Descriptive and cross-sectional by design. It was Descriptive in design because it intends to descriptive identify risk factors associated with medical sharps injury among health workers at Kismayo Private Hospitals, Kismayo, Somalia. It will also adopt a cross-sectional research design because it intends to collect in a specific point time.

Results

The majority of respondents (72%) identify as male, followed by 26% who identify as female. A small percentage of respondents (2%) prefer not to disclose their gender. The table presents the age distribution of a sample of 50 respondents. The vast majority of respondents (92%) fall within the 25-30 age group, followed by 6% in the 35-40 age group and 2% in the 30-35 age group. The table represents the distribution of respondents by occupational level.

The recommendations and conclusion are This study looked into the risk variables for medical sharps injuries among healthcare professionals working at Somalia's Kismayo Private Hospitals.  Medical sharps injuries pose a significant risk to healthcare professionals working at Somalia's Kismayo Private Hospitals. These injuries can lead to various health complications and transmit infectious diseases. Several risk variables contribute to the occurrence of such incidents, and understanding these factors is crucial for implementing effective preventive measures. Addressing these risk variables requires a comprehensive approach that includes training programs, provision of safety equipment, improved infrastructure, strict adherence to safety protocols, robust reporting systems, vaccination campaigns, and effective sharps waste management. By addressing these factors, healthcare professionals can work in a safer environment and reduce the incidence of sharps injuries at Kismayo Private Hospitals in Somalia.

description: The sensitive conductance change of semiconductor nanowires and carbon nanotubes in response to binding of charged molecules provide a novel sensing modality which is generally denoted as nanoFET sensors. In this paper, we study the scaling laws of nanoplate FET sensors by simplifying nanoplates as random resistor networks with molecular receptors sitting on lattice sites. Nanowire/tube FETs are included as the limiting cases where the device width goes small. Computer simulations show that the field effect strength exerted by the binding molecules has significant impact on the scaling behaviors. When the field effect strength is small, nanoFETs have little size and shape dependence. In contrast, when the field-effect strength becomes stronger, there exists a lower detection threshold for charge accumulation FETs and an upper detection threshold for charge depletion FET sensors. At these thresholds, the nanoFET devices undergo a transition between low and large sensitivities. These thresholds may set the detection limits of nanoFET sensors, while could be eliminated by designing devices with very short source-drain distance and large width.

description: We use numerically unbiased methods to show that the one-dimensional Hubbard model with periodically distributed on-site interactions already contains the minimal ingredients to display the phenomenon of magnetoresistance; i.e., by applying an external magnetic field, a dramatic enhancement on the charge transport is achieved. We reach this conclusion based on the computation of the Drude weight and of the single-particle density of states, applying twisted boundary condition averaging to reduce finite-size effects. The known picture that describes the giant magnetoresistance, by interpreting the scattering amplitudes of parallel or antiparallel polarized currents with local magnetizations, is obtained without having to resort to different entities; itinerant and localized charges are indistinguishable.

description: The valley method for computing the total high-energy anomalous cross section $S_{anom}$ is the extension of the optical theorem to the case of instanton-antiinstanton backgrounds. As a toy model for baryon number violation in Electroweak theory, we consider a version of the $O(3)$ $σ$ model in which the conformal invariance is broken perturbatively. We show that at a critical energy the saddle-point values of the instanton size and instanton-antiinstanton separation bifurcate into complex conjugate pairs. This nonanalytic behavior signals the breakdown of the valley method at an energy where $S_{anom}$ is still exponentially suppressed. (Figures replaced 5/3/93).

description: Traffic state estimation (TSE) aims to estimate the time-varying traffic characteristics (such as flow rate, flow speed, flow density, and occurrence of incidents) of all roads in traffic networks, provided with limited observations in sparse time and locations. TSE is critical to transportation planning, operation and infrastructure design. In this new era of “big data”, massive volumes of sensing data from a variety of source (such as cell phones, GPS, probe vehicles, and inductive loops, etc.) enable TSE in an efficient, timely and accurate manner. This research develops a Bayesian-based theoretical framework, along with statistical inference algorithms, to (1) capture the complex flow patterns in the urban traffic network consisting both highways and arterials; (2) incorporate heterogeneous data sources into the process of TSE; (3) enable both estimation and perdition of traffic states; and (4) demonstrate the scalability to large-scale urban traffic networks. To achieve those goals, a Hierarchical Bayesian probabilistic model is proposed to capture spatio-temporal traffic states. The propagation of traffic states are encapsulated through mesoscopic network flow models (namely the Link Queue Model) and equilibrated fundamental diagrams. Traffic states in the Hierarchical Bayesian model are inferred using the Expectation-Maximization Extended Kalman Filter (EM-EKF). To better estimate and predict states, infrastructure supply is also estimated as part of the TSE process. It is done by adopting a series of algorithms to translate Twitter data into traffic incident information. Finally, the proposed EM-EKF algorithm is implemented and examined on the road networks in Washington DC. The results show that the proposed methods can handle large-scale traffic state estimation, while achieving superior results comparing to traditional temporal and spatial smoothing methods.
Magnetically-charged supersymmetric flows of gauged $\mathcal{N}\,=\,8$ supergravity in five dimensions

description: We study magnetically-charged supersymmetric flow equations in a consistent truncation of gauged $\mathcal{N}\,=\,8$ supergravity in five dimensions. This truncation gives gauged $\mathcal{N}\,=\,2$ supergravity coupled to two vector multiplets and two hypermultiplets. We derive magnetically-charged flow equations of scalar fields from vector and hypermultiplets. It turns out that there could be only up to two nontrivial scalar fields out of eight from the hypermultiplets. Along the way, we recover some known $AdS_3$ solutions of the flow equations.

description: Every year, the number of cases of mammoplasty performed for cosmetic reasons increases.  However, operations on the mammary glands (MG) are often performed not only for aesthetic reasons.  The trend of increasing incidence of breast cancer (BC) in women continues [1–3].  Among the technologies for combined treatment of patients with breast cancer, the surgical method remains fundamental.  Moreover, both radical mastectomy and partial resections of gl.mammae after surgery are invariably accompanied by the formation of breast deformities.  The latter causes a deterioration in the quality of life of women with breast cancer, reducing the possibility of their rapid social adaptation [4].

description: Report 3, published 19 July 2021. Fully open-access.
We conducted a nationally representative online survey in Ghana (N = 1295) throughout June 2021.

In our analyses, we operationalised vaccine hesitancy as respondents who answered ‘no’ and ‘I don’t know’ to the question: “When a COVID-19 vaccine becomes available to you, would you like to get vaccinated?”
Some top-level findings to share
 - willingness to vaccinate dropped from 82% in March, to 71% in June 2021
 - Therefore, to phrase another way, there was an observed and significant increase in hesitancy, from 18% to 29% across this time period.
 - 32% of respondents reported that they had recently seen or heard stories about the indecision surrounding the Oxford Astrazeneca vaccine rollout in Europe and North America. Of this 32% subgroup, 62.0% of them indicated that these stories made them feel worried about accepting the COVID-19 vaccine in the future.
 - our main predictors of hesitancy continue to include: i) education (more educated people were more likely to be hesitant; one hypothesis is perhaps more likely to have greater access to the internet and thus availability of misinformation via social media); ii) females more hesitant than males; and iii) political allegiance (voting for the opposition parties was greater predictor of hesitancy). We hope that this information can be helpful with informing the health promotion efforts from the GHS, Ministry of Health and other stakeholders.

description: The three generation mirror fermion model is compared with LEP precision and low energy data. While for zero mixing of ordinary and mirror fermions the model is not favoured, for non zero mixing very low $χ^2 $ fits have been obtained, in particular when right handed leptonic mixings are small and left handed leptonic mixings are large (of the order of 0.1 radians.)

description: Two-dimensional topological superconductivity has attracted great interest due to the emergence of Majorana modes bound to vortices and propagating along edges. However, due to its rare appearance in natural compounds, experimental realizations rely on a delicate artificial engineering involving materials with helical states, magnetic fields and conventional superconductors. Here we introduce an alternative path using a class of three-dimensional antiferromagnet to engineer a two- dimensional topological superconductor. Our proposal exploits the appearance of solitonic states at the interface between a topologically trivial antiferromagnet and a conventional superconductor, which realize a topological superconducting phase when their spectrum is gapped by intrinsic spin- orbit coupling. We show that these interfacial states do not require fine-tuning, but are protected by asymptotic boundary conditions.

description: The Soft X-ray intensity of loops in active region cores and corresponding footpoint, or moss, intensity observed in the EUV remain steady for several hours of observation. The steadiness of the emission has prompted many to suggest that the heating in these loops must also be steady, though no direct comparison between the observed X-ray and EUV intensities and the steady heating solutions of the hydrodynamic equations has yet been made. In this paper, we perform these simulations and simultaneously model the X-Ray and EUV moss intensities in one active regioncore with steady uniform heating. To perform this task, we introduce a new technique to constrain the model parameters using the measured EUV footpoint intensity to infer a heating rate. We find that a filling factor of 8% and loops that expand with height provides the best agreement with the intensity in two X-ray filters, though the simulated SXT Al12 intensity is 147% the observed intensity and the SXT AlMg intensity is 80% the observed intensity. From this solution, we determine the required heating rate scales as ${\bar{B}}^{0.29} L^{-0.95}$. Finally we discuss the future potential of this type of modeling, such as the ability to use density measurements to fully constrain filling factor, and its shortcomings, such as the requirement to use potential field extrapolations to approximate the coronal field.
