description: By substituting the Fe with the 4d and 5d-transition metals Rh, Ir and Pd in SrFe_2As_2, we have successfully synthesized a series of superconductors SrFe_{2-x}M_xAs_2 (M = Rh, Ir and Pd) and explored the phase diagrams of them. The systematic evolution of the lattice constants indicated that part of the Fe ions were successfully replaced by the transition metals Rh, Ir and Pd. By increasing the doping content of Rh, Ir and Pd, the antiferromagnetic state of the parent phase is suppressed progressively and superconductivity is induced. The general phase diagrams were obtained and found to be similar to the case of doping Co and Ni to the Fe sites. However, the detailed structure of the phase diagram, in terms of how fast to suppress the antiferromagnetic order and induce the superconductivity, varies from one kind of doped element to another. Regarding the close values of the maximum superconducting transition temperatures in doping Co, Rh and Ir which locate actually in the same column in the periodic table of elements but have very different masses, we argue that the superconductivity is intimately related to the suppression of the AF order, rather than the electron-phonon coupling.

description: The global incidence of heart disease is growing in our aging population at an alarming rate. One type of blood pressure-lowering medication designed to block the mineralocorticoid receptor (MR) protein in cells has shown to reduce heart disease-related hospitalisation and death. However, the use of these MR blockers is limited in some patients and can only be prescribed in less-than-optimal doses due to the risk of major side-effects in the kidney. Therefore, the goal of this project was to reveal new knowledge about actions of MR in the damaged heart to identify new ways to block its activity without compromising kidney function.
Computer Mediated Collaborative Word Search in Online Tutoring: A Single Case Analysis

description: As internet-based remote communication became one of the primary modes for human interaction, particularly when it has been adopted in instructional and educational contexts, researchers have begun exploring various features of the interactions occurring on or mediated by these platforms. Garcia and Jacobs (1999) examined students’ exchanges on a text-based quasi-synchronous discussion program and found that the turn-taking system differs greatly from naturally-occurring face-to-face interactions such as turn-allocation and projection. Computermediated collaboration is also another topic that has been extensively addressed (See for example Heath & Luff, 1992; Luff et al, 2003). It has been found that video-mediated interactional environment can impact participants’ interactional conduct and introduce communicative asymmetries (Heath & Luff, 1992). This short paper analyzes one word-search episode between a teacher and a student during a web-based language tutoring session and demonstrates how the sequence is collaboratively conducted and resolved.

description: We present results from a WIYN/OPTIC photometric and astrometric survey of the field of the open cluster NGC 188 ((l,b) = (122.8\arcdeg, 22.5\arcdeg)). We combine these results with the proper-motion and photometry catalog of Platais et al. and demonstrate the existence of a stellar overdensity in the background of NGC 188. The theoretical isochrone fits to the color-magnitude diagram of the overdensity are consistent with an age between 6 and 10 Gyr and an intermediately metal poor population ([Fe/H] = -0.5 to -1.0). The distance to the overdensity is estimated to be between 10.0 and 12.6 kpc. The proper-motions indicate that the stellar population of the overdensity is kinematically cold. The distance estimate and the absolute proper motion of the overdensity agree reasonably well with the predictions of the Peñarrubia et al. model of the formation of the Monoceros stream. Orbits for this material constructed with plausible radial-velocity values, indicate that dynamically, this material is unlikely to belong to the thick disk. Taken together, this evidence suggests that the newly-found overdensity is part of the Monoceros stream.

Contribution with Hand-Raising in Graduate Student Self-Selection: Bringing Legitimacy to the Focal Shift of Talk
Creators: name: Takahashi, Junko
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2016

description: Hand-raising is an extremely useful device for classroom self-selection. According to Sahlström (2002), it exhibits a student’s willingness to participate, and is a means by which to attract the attention of the teacher. Kawabe, Yamamoto, Aoyagi, and Watanabe (2014) analyzed various situations and student factors to affect hand-raising in the classroom. The practice of hand-raising is generally found to occur at the teacher’s turn transition relevant places, or TRPs (Sacks, Schegloff, & Jefferson, 1974). The conventional process of self-selection with hand-raising involves a student bidding for a nomination, and the self-selector becoming ratified to speak after the teacher nomination is provided. It was also suggested that later bidders tend to be selected more frequently than the first bidders, who may raise their hands slightly prior to the teacher’s early TRPs. Thus, “teachers may reward the late hand-raisers for sufficient listening” (Sahlström, 2002, p. 53-54).

description: Active Internet measurements face challenges when some measurements require many remote vantage points. In this paper, we propose a novel technique for measuring remote IPv6 networks via side channels in ICMP rate limiting, a required function for IPv6 nodes to limit the rate at which ICMP error messages are generated. This technique, iVantage, can to some extent use 1.1M remote routers distributed in 9.5k autonomous systems and 182 countries as our "vantage points". We apply iVantage to two different, but both challenging measurement tasks: 1) measuring the deployment of inbound source address validation (ISAV) and 2) measuring reachability between arbitrary Internet nodes. We accomplish these two tasks from only one local vantage point without controlling the targets or relying on other services within the target networks. Our large-scale ISAV measurements cover ~50% of all IPv6 autonomous systems and find ~79% of them are vulnerable to spoofing, which is the most large-scale measurement study of IPv6 ISAV to date. Our method for reachability measurements achieves over 80% precision and recall in our evaluation. Finally, we perform an Internet-wide measurement of the ICMP rate limiting implementations, present a detailed discussion on ICMP rate limiting, particularly the potential security and privacy risks in the mechanism of ICMP rate limiting, and provide possible mitigation measures. We make our code available to the community.
Embodied Vocabulary Explanation in ESL Group Interaction: A Preliminary Account

description: In recent decades, the study of language learners’ embodied behavior amongst themselves has gained much currency. Broadly speaking, a wealth of studies on learner gestures connect gestures with second language acquisition, and have shown that gestures play a role in facilitating communication, acquisition, and retention (Gullberg, 1998, 2011, 2014; McCafferty, 2004; McCafferty & Gullberg, 2008; Stam & McCafferty, 2008). Another line of research examines learner gestures through the lens of sociocultural theory, and has found that learners use gestures to rehearse new knowledge and to self-regulate (Lee, 2008; McCafferty, 1998; Negueruela & Lantolf, 2008; Platt & Brooks, 2008). These studies, however, adopted experimental designs as a research method, and therefore, how learners actually use gestures when interacting with one another in situ remains largely a “black box.”

description: Weak-coupling approaches to the pairing problem in the iron pnictide superconductors have predicted a wide variety of superconducting ground states. We argue here that this is due both to the inadequacy of certain approximations to the effective low-energy band structure, and to the natural near-degeneracy of different pairing channels in superconductors with many distinct Fermi surface sheets. In particular, we review attempts to construct two-orbital effective band models, the argument for their fundamental inconsistency with the symmetry of these materials, and the comparison of the dynamical susceptibilities in two- and five-orbital models. We then present results for the magnetic properties, pairing interactions, and pairing instabilities within a five-orbital Random Phase Approximation model. We discuss the robustness of these results for different dopings, interaction strengths, and variations in band structure. Within the parameter space explored, an anisotropic, sign-changing s-wave state and a d_x2-y2 state are nearly degenerate, due to the near nesting of Fermi surface sheets.

description: As it becomes increasingly apparent that nonverbal conduct plays an integral role in pedagogical interactions (McCafferty & Stam, 2008; Zwiers, 2007), researchers who study interaction in situ are shifting focus from solely talk toward a multimodal approach (Lazaraton, 2004; Olsher, 2004; Seo & Koshik, 2010; Taylor, 2014). From this body of research, a finding of particular interest is that teachers use nonverbal resources to manage logistics in the classroom. For example, Kääntä (2010) found that teachers allocate turns to students by obtaining mutual gaze followed by nodding. Furthermore, Cekaite (2015) found that teachers use sustained touch to get students to comply with verbal directives. This paper contributes to the growing body of research on nonverbal conduct in pedagogical interaction by examining the multimodal resources used by an English as a Second Language (ESL) tutor to manage a young student’s participation in a one-on-one interaction.

description: As a methodological approach that studies naturally occurring social interaction in various settings, conversation analysis (CA) uncovers how social actions are organized in the moment-by-moment details of interaction and how participants as Members make sense of each other in situ (Psathas, 1995; ten Have, 2007). Due to technological limitations, early CA research largely relied on audio recordings of telephone conversations (see Lerner [2004] for a collection of first-generation studies on topics including turn-taking and sequence organization). From the 1970s, as video recordings became a possibility, CA pioneers also started to turn their attention to the interactional details and multimodal resources visibly accessible in face-to-face interaction. Issues addressed in their seminal work include how listenership can be displayed through gaze and other embodied behaviors, and how mutual orientation is established through gestures and other embodied resources (Goodwin, 1981; Heath, 1986). Overall, such work on multimodality views social interaction as Members’ practical actions organized by and accomplished through concerted talk and embodied actions, and investigates interactional resources available through the visual, auditory, and haptic channels as made relevant by participants of an interaction.

description: In recent years, spammers are now trying to obfuscate their intents by introducing hybrid spam e-mail combining both image and text parts, which is more challenging to detect in comparison to e-mails containing text or image only. The motivation behind this research is to design an effective approach filtering out hybrid spam e-mails to avoid situations where traditional text-based or image-baesd only filters fail to detect hybrid spam e-mails. To the best of our knowledge, a few studies have been conducted with the goal of detecting hybrid spam e-mails. Ordinarily, Optical Character Recognition (OCR) technology is used to eliminate the image parts of spam by transforming images into text. However, the research questions are that although OCR scanning is a very successful technique in processing text-and-image hybrid spam, it is not an effective solution for dealing with huge quantities due to the CPU power required and the execution time it takes to scan e-mail files. And the OCR techniques are not always reliable in the transformation processes. To address such problems, we propose new late multi-modal fusion training frameworks for a text-and-image hybrid spam e-mail filtering system compared to the classical early fusion detection frameworks based on the OCR method. Convolutional Neural Network (CNN) and Continuous Bag of Words were implemented to extract features from image and text parts of hybrid spam respectively, whereas generated features were fed to sigmoid layer and Machine Learning based classifiers including Random Forest (RF), Decision Tree (DT), Naive Bayes (NB) and Support Vector Machine (SVM) to determine the e-mail ham or spam.

description: This thesis focuses on the patient-centred outcome measure of disability, as measured by the World Health Organization Disability Assessment Schedule 2.0 (WHODAS). I confirmed that WHODAS is a valid, reliable, responsive and acceptable measure of disability in a surgical population, and estimated the WHODAS scale values that define the minimal clinically important difference, patient acceptable symptom state and clinically significant disability.

The remainder of the thesis concerns the ability of exercise testing and other assessments of functional capacity to predict disability after surgery in various surgical populations. A point-score model was developed to predict postoperative disability-free survival in the elderly.

Insights into virus-mediated proteolysis of host cell proteins during positive-sense RNA virus infection
Creators: name: Andrews, Daniel Donald Thomas
Publisher: name: University of British Columbia
Year: 2023

description: Viruses must co-opt host cellular functions to facilitate virus infection in cells. To accomplish this, they have evolved diverse strategies to hijack the host cell for its own benefit. One such strategy is through the activity of virus-encoded proteases, which are not only essential for viral polyprotein processing, but also for the cleavage of host cell proteins to modulate cellular pathways such as translation and innate immunity. While enterovirus proteases such as 2A and 3C have been well-studied and target many host proteins, the flaviviral NS2B-NS3 protease is poorly characterized and only a few host protein targets have been identified to date. In this thesis, I hypothesized that the cleavage of currently unidentified host proteins promotes the modulation and hijacking of host cellular processes. The N-terminomics based approach terminal amine isotopic labeling of substrates (TAILS) was employed to identify protease-generated N-termini and host substrates cleaved during virus infection. Three primary aims were addressed: first, characterizing the cleavage of the adapter protein 14-3-3ε by the enteroviral 3Cᴾʳº; next, identifying substrates of the Zika virus (ZIKV) NS2B-NS3ᴾʳº in human A549 cells during infection; finally, to conduct a global analysis of protease-generated N-termini, including both viral and cellular protease substrates, in human and mosquito cell lines. Characterizing the cleavage of 14-3-3ε by 3Cᴾʳº resulted in two key observations: (i) cleavage of 14-3-3ε promotes virus infection and (ii) the newly formed N-terminal fragment represses RIG-I signalling. TAILS analysis of ZIKV-infected A549 cells also uncovered host proteins cleaved during virus infection, including the RNA binding protein HNRNPH3 which was found to be cleaved by NS2B-NS3ᴾʳº. Moreover, TAILS provided insights into the proteolytic activity of viral and cellular proteases during ZIKV infection in human (A549) and mosquito (C6/36) cell lines, shedding light on protease specificity and subcellular localization of these targets. In summary, TAILS identified novel targets of viral and cellular proteases during infection, enhancing our understanding of the biological pathways disrupted during picornavirus and flavivirus infection and offering potential therapeutic or antiviral targets against viral protease activity.

description: Inpainting-based image compression is a promising alternative to classical transform-based lossy codecs. Typically it stores a carefully selected subset of all pixel locations and their colour values. In the decoding phase the missing information is reconstructed by an inpainting process such as homogeneous diffusion inpainting. Optimising the stored data is the key for achieving good performance. A few heuristic approaches also advocate alternative feature types such as derivative data and construct dedicated inpainting concepts. However, one still lacks a general approach that allows to optimise and inpaint the data simultaneously w.r.t. a collection of different feature types, their locations, and their values. Our paper closes this gap. We introduce a generalised inpainting process that can handle arbitrary features which can be expressed as linear equality constraints. This includes e.g. colour values and derivatives of any order. We propose a fully automatic algorithm that aims at finding the optimal features from a given collection as well as their locations and their function values within a specified total feature density. Its performance is demonstrated with a novel set of features that also includes local averages. Our experiments show that it clearly outperforms the popular inpainting with optimised colour data with the same density.

description: A dual formulation of the S Matrix for N=4 SYM has recently been presented, where all leading singularities of n-particle N^{k-2}MHV amplitudes are given as an integral over the Grassmannian G(k,n), with cyclic symmetry, parity and superconformal invariance manifest. In this short note we show that the dual superconformal invariance of this object is also manifest. The geometry naturally suggests a partial integration and simple change of variable to an integral over G(k-2,n). This change of variable precisely corresponds to the mapping between usual momentum variables and the "momentum twistors" introduced by Hodges, and yields an elementary derivation of the momentum-twistor space formula very recently presented by Mason and Skinner, which is manifestly dual superconformal invariant. Thus the G(k,n) Grassmannian formulation allows a direct understanding of all the important symmetries of N=4 SYM scattering amplitudes.

description: Floquet time crystal, which breaks discrete time-translation symmetry, is an intriguing phenomenon in non-equilibrium systems. It is crucial to understand the rigidity and robustness of discrete time crystal (DTC) phases in a many-body system, and finding a precisely solvable model can pave a way for understanding of the DTC phase. Here, we propose and study a solvable spin chain model by mapping it to a Floquet superconductor through the Jordan-Wigner transformation. The phase diagrams of Floquet topological systems are characterized by topological invariants and tell the existence of anomalous edge states. The sub-harmonic oscillation, which is the typical signal of the DTC, can be generated from such edge states and protected by topology. We also examine the robustness of the DTC by adding symmetry-preserving and symmetry-breaking perturbations. Our results on topologically protected DTC can provide a deep understanding of the DTC when generalized to other interacting or dissipative systems.

description: We construct new supersymmetric $\mathrm{AdS}_2\times \mathbb{M}_4$ solutions of $D=6$ gauged supergravity, where $\mathbb{M}_4$ are certain four-dimensional orbifolds. After uplifting to massive type IIA supergravity these correspond to the near-horizon limit of a system of $N$ D4-branes and $N_f$ D8-branes wrapped on $\mathbb{M}_4$. In one class of solutions $\mathbb{M}_4 = Σ_{\mathrm{g}}\ltimesΣ$ is a spindle fibred over a smooth Riemann surface of genus $\mathrm{g}>1$, while in another class $\mathbb{M}_4 = Σ\ltimesΣ$ is a spindle fibred over another spindle. Both classes can be thought of as orbifold generalizations of Hirzebruch surfaces and, in the second case, we describe the solutions in terms of toric geometry. We show that the entropy associated with these solutions is reproduced by extremizing an entropy function obtained by gluing gravitational blocks, using a general recipe for orbifolds that we propose. We also discuss how our prescription can be used to define an off-shell central charge whose extremization reproduces the gravitational central charge of analogous $\mathrm{AdS}_3\times \mathbb{M}_4$ solutions of $D=7$ gauged supergravity, arising from wrapping M5-branes on $\mathbb{M}_4$.

We compare the equations of the DTT and the second-order theory (based on conformal invariants), for the case of Bjorken ow. The approach to ideal hydrodynamics is faster in the DTT, indicating that our results can be useful in the study of early-time dynamics in relativistic heavy-ion collisions.

The original paths are naturally deformed into those in the complex plane, permitting us to convert into an $su(n)$ extension of the unitary matrix model of GWW type with a set of log potentials for all species of eigenvalues. Looking at the region in the parameter space that enjoys the maximal symmetry of the model, we derive a set of relations among the mass parameters which may serve as evidence for the existence of the Argyres-Douglas critical hypersurface.

description: We study the properties of electromagnetic Bloch waves in semi-infinite periodic structures created by alternating metamaterial and dielectric layers. We derive and analyze the dispersion relations in the long-wavelength limit for both TE- and TM-polarized surface Bloch modes, for magnetic metamaterials with negative refraction and metal-dielectric plasmonic superlattices. We reveal that in the subwavelength regime the bulk modes are characterized by three different refractive indices ("tri-refringence") while the surface modes can propagate parallel to the Bloch wavevector and along the interface between superlattice and semi-infinite dielectric.

description: Two new tigliane- and daphnane-type diterpenoids, given the trivial names daphnegens A–B (1–2) were isolated from the buds of Daphne genkwa. Their structures were assigned on the basis of extensive spectroscopic. The absolute configurations of both compounds were determined by comparison of their calculated and experimental CD curves. In addition, compounds 1–2 were tested for their cytotoxic activities against MCF-7 and HepG-2 human cancer cell lines, and compound 2 showed remarkable cytotoxic activity against HepG-2 cell line with the IC50 value of 11.5 μM.

description: The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio telescope that we built to map the large-scale structure of the Universe between redshifts 0.8 and 2.5, when dark energy is expected to begin the transition from a decelerating to an accelerating phase in the expansion of the Universe. CHIME was designed to perform an intensity mapping survey using the 21 cm line of neutral hydrogen, a novel method that has the potential to enable enormous surveys of the distant Universe, but also significant observational challenges to overcome. In this thesis, I describe contributions I made to the CHIME data acquisition system and calibration effort, culminating in a detection of cosmological 21 cm emission in cross-correlation with measurements of the Lyman-𝜶 forest. The large data rate from the CHIME correlator is processed in real time by a high-performance digital pipeline, the development of which I participated in extensively. A few specific processing tasks where I led the design and implementation are highlighted in this work. In order to detect the 21 cm signal amidst the much brighter foreground emission from nearby sources, a very precise instrumental calibration is required. Calibrating the telescope's beam is a particular concern. One of many approaches being pursued for CHIME is the holographic observation of bright celestial sources in concert with a second radio telescope. I describe work I did to derive beam measurements from such observations and their analysis, including a scheme for calibrating the polarised beam response. I report the detection of 21 cm emission at an average redshift z = 2.3 in the cross-correlation of CHIME maps with measurements of the Lyman-𝜶 forest from the eBOSS. Data collected by CHIME over 88 days in the 400-500 MHz frequency band (1.8 < z < 2.5) were formed into maps of the sky and high-pass delay filtered to suppress the foreground power. Line-of-sight spectra to the eBOSS background quasar locations were extracted from the CHIME maps and combined with the Lyman-𝜶 forest flux transmission spectra to estimate the 21 cm-Lyman-𝜶 cross-correlation function. Fitting a simulation-derived template to this measurement results in a detection of 9-𝝈 significance.

description: An experiment utilizing a TlF molecular beam is being developed by the CeNTREX collaboration to search for hadronic interactions that violate both time-reversal (T) and parity (P) invariance. Here we propose to use the same beam to look for a T-invariance conserving but P-nonconserving (PNC) effect induced by the anapole moment of the Tl nucleus, via a vector coupling of the two nuclear spins in TlF. To measure the nuclear anapole moment, the dc electric and magnetic fields in CeNTREX are replaced by rf fields resonant with a nuclear spin flip transition. We adapt the relativistic coupled cluster method in a combination with relativistic density functional theory for the calculation of the molecular PNC spin-spin vector coupling constant that links the experimental signal with the anapole moment. The value of the P-conserving spin-spin coupling constant calculated within the same approach is found to be in good agreement with available experimental data.

description: Sequential sexual practices involving the oropharynx and saliva may increase the transmission of Neisseria gonorrhoeae and Chlamydia trachomatis at multiple anatomical sites in MSM. For Mycoplasma genitalium, only oral and anal sex can explain the transmission at multiple anatomical sites without the need to invoke transmission by kissing or rimming. Machine learning predictive models based on self-reported questions can predict the current and future risk of HIV/STIs acquisition and have been translated into a web-based prediction tool named MySTIRisk. Using routinely collected data in clinical settings, machine learning algorithms also can predict clinic visits and HIV/STIs testing.

description: We use trajectory averaging to show that the energy dissipated in the nonequilibrium energy-state transitions of a driven two-state system satisfies a fluctuation-dissipation relation. This connection between the average energy dissipation induced by external driving and its fluctuations about equilibrium is preserved by an adiabatic approximation scheme. We use this scheme to obtain the heat statistics of a single-electron box with superconducting leads in the slow-driving regime, where the dissipated heat becomes normally distributed with a relatively high probability to be extracted from the environment rather than dissipated. We also discuss heat fluctuation relations for driven two-state transitions.

description: A new lanostane-type triterpene, namely 3-oxo-5α-lanosta-7,9(11)-dien-24-oic acid methyl ester (2), and three known compounds including ganoderal A (1), ganoderiol B (3) and ganodermenonol (4) were isolated from the fruiting bodies of Ganoderma lucidum by silica gel column chromatography and Sephadex LH-20 column chromatography. Their structures were determined by extensive NMR data and mass spectral analysis. The in vitro cytotoxic activity of the isolated compounds against SK-Hep-1, HepG2, Hela and Hela/VCR cancer cell lines was assessed by using MTT assay. The IC50 values of compound 1 were 43.09 ± 2.86, 42.31 ± 1.78 and 46.51 ± 1.95 μM in SK-Hep-1, HepG2 and Hela cells, respectively, after 48 h. The IC50 values of compound 4 were 44.70 ± 2.32 and 41.33 ± 2.15 μM in Hela and Hela/VCR cells, respectively, after 48 h.
Learners’ privilege and responsibility: A critical examination of the experiences and perspectives of learners from Chinese backgrounds in the United States

description: According to the Institute of International Education (2013), Chinese students from K-12 to higher education account for approximately 25% of all international students in the United States. As a result, it is imperative that educators show concern and support for them, as they are shaped by the culture of their home country and challenged by the culture of their adopted country. While researchers have explored how to help socialize English language learners into the American education system either for learning or teaching purposes (e.g., Harklau, 2003; Reinhardt & Zander, 2011), few have focused on Chinese students in the United States. Ma and Wang’s (2014) Learners’ Privilege and Responsibility, which includes contributions from several international scholars, fills this gap by presenting a wide scope of research topics on Chinese students from K-12 to higher education. This book aims to reveal “the complexity of this group of students and the challenges they face as a whole” (p. xiii), while at the same time suggesting how their academic and social challenges in the United States can be addressed by taking into account their prior educational and social experiences in China.

description: The EFIELD instrument is part of the geophysics and meteorology sensor package DraGMet on the Dragonfly mission, which will explore the surface of Titan in the mid-2030s. EFIELD consists of two electrodes designed to passively record the AC electric field at each landing site. The exploration zone of Dragonfly will mostly consist of dune fields, covered with sand grains. Little is known on the properties of these grains, although Cassini-Huygens observations suggest they are mostly made of organic material produced by Titan's atmospheric photochemistry and evolved at the surface. Little is known also about dune formation and in general about the transport of sediments by winds. The latter much depends on inter-particle forces and therefore on how grains are charged by friction. We demonstrate here that the EFIELD experiment can bring new insights on these questions. We have developed a hydrodynamic-electrostatic model to simulate the trajectory of a wind-blown charged sand grain in the vicinity of an idealized EFIELD probe and to predict how such a grain flying close to the probe would affect its potential. We show that, in some conditions, the resulting perturbation will be strong enough to be detected by the EFIELD probe. More specifically, we find that the detection of typical charged wind-blown grains (200 microns) on Titan requires an instrument standard deviation noise inferior to 1mV, though occasional larger grains flying close to one electrode could be detected with a higher noise level. Furthermore, we propose a method to retrieve information on the charge and velocity of wind-blown charged grains detected by the EFIELD experiment. This method well applies for cases where the particle trajectory can be regarded as quasi-linear. We validate our inversion approach on both synthetic and experimental data obtained with a laboratory prototype of the EFIELD experiment.

description: The transport coefficients of causal relativistic dissipative fluid dynamics are calculated both in a field-theoretical and a kinetic approach. We find that the results from the traditional kinetic calculation by Israel and Stewart are modified. The new expressions for the viscous transport coefficients agree with the results obtained in the field-theoretical approach when the contributions from pair creation and annihilation are neglected.
