description: A flow-loop apparatus, incorporating a co-current double-pipe heat exchanger, was developed for investigating the deposition of solids from multi-component solutions of a wax and a paraffinic solvent under turbulent flow. The deposition experiments were performed at Reynolds numbers from 10000 to 31000 with 7, 10 and 15 mass% wax­solvent mixtures at different hot and cold stream temperatures. In all experiments, the deposit was formed rapidly, with thermal steady-state attained within 20-30 min. The deposit mass decreased with an increase in the Reynolds number, the wax-solvent mixture temperature, and the coolant temperature. The data were analyzed with a steady­state heat-transfer model, which confirmed the deposit mass to depend on the relative magnitudes of the thermal resistances in series as well as the fractional temperature drop across the deposit-layer. The estimated liquid-deposit interface temperature was shown to be the wax appearance temperature (WAT) of each wax-solvent mixture within experimental error limits. The average thermal conductivity of the deposits was estimated to be 0.35 W m-1 K-1• The GC analysis of deposit samples showed their wax content and carbon number distribution to vary with the deposition time and Reynolds number. Overall, the results of this study, together with results obtained previously under laminar flow, confirm that the deposition process from 'waxy' mixtures is primarily thermally-driven under both laminar and turbulent flow regimes.

description: We study the dielectric function of the homogeneous semiconductor hole liquid of p-doped bulk III-V zinc-blende semiconductors within random phase approximation. The single-particle physics of the hole system is modeled by Luttinger's four-band Hamiltonian in its spherical approximation. Regarding the Coulomb-interacting hole liquid, the full dependence of the zero-temperature dielectric function on wave vector and frequency is explored. The imaginary part of the dielectric function is analytically obtained in terms of complicated but fully elementary expressions, while in the result for the real part nonelementary one-dimensional integrations remain to be performed. The correctness of these two independent calculations is checked via Kramers-Kronig relations. The mass difference between heavy and light holes, along with variations in the background dielectric constant, leads to dramatic alternations in the plasmon excitation pattern, and generically, two plasmon branches can be identified. These findings are the result of the evaluation of the full dielectric function and are not accessible via a high-frequency expansion. In the static limit a beating of Friedel oscillations between the Fermi wave numbers of heavy and light holes occurs.

description: Papermaking is a major industry to manufacture products vital to education, communication, and packaging. Most operations in this industry deal with the flow of different mass concentrations of pulp suspensions. Therefore, the flow properties (rheology) of pulp suspensions are of great importance for the optimal functionality of most unit operations in the industry. Yield stress is one of the most important rheological properties in designing process equipment, thus needs to be determined by a reliable technique. Two established and extensively used methods for determining yield stress were compared with a velocimetry technique. The yield stresses were determined for commercial pulp suspensions at fibre mass concentrations of 0.5 to 5 wt. %. The results were compared and models were proposed to predict the yield stress as a function of fibre mass concentration. The yield stress values obtained by the velocimetry technique were found to be the most reliable. Conventional rheometry and local velocimetry techniques were further used to study the flow behaviour of pulp suspensions beyond the yield stress. Pulp suspensions were found to be shear-thinning up to a certain high shear rate. The Herschel–Bulkley constitutive equation was used to fit the local steady-state velocity profiles and to predict the steady-state flow curves obtained by conventional rheometry. Conventional rheometry was found to fail at low shear rates due to the presence of wall slip. Consistency between the various sets of data was found for all suspensions studied. Finally, the same approach was used to study thixotropy and transient flow behaviour of concentrated pulp suspension of 6 wt.%. Pulp was found to exhibit a plateau in the flow curve where a slight increase in the shear stress generated a jump in the corresponding shear rate, implying the occurrence of shear banding. The velocity profiles were found to be discontinuous in the vicinity of the yielding radius where a Herschel-Bulkley model failed to predict the flow. Shear history and the time of rest prior to the measurement were found to play a significant role on the rheology and the local velocity profiles of pulp suspension.

description: In this study, we investigated the effects of specific low-frequency electromagnetic field sequences on U937 cells, an in vitro model of human monocyte/macrophage differentiation. U937 cells were exposed to electromagnetic stimulation by means of the SynthéXer system using two similar sequences, XR-BC31 and XR-BC31/F. Each sequence was a time series of 29 wave segments, equal to a total duration of 77 min. Here, we report that exposure (4 d, once a day) of U937 cells to the XR-BC31 setting, but not to the XR-BC31/F, resulted in increased expression of the histone demethylase KDM6B along with a global reduction in histone H3 lysine 27 tri-methylation (H3K27me3). Furthermore, exposure to the XR-BC31 sequence induced differentiation of U937 cells towards a macrophage-like phenotype displaying a KDM6B dependent increase in expression and secretion of the anti-inflammatory interleukins (ILs), IL-10 and IL-4. Importantly, all the observed changes were highly dependent on the nature of the sequence. Our results open a new way of interpretation for the effects of low-frequency electromagnetic fields observed in vivo. Indeed, it is conceivable that a specific low-frequency electromagnetic fields treatment may cause the reprogramming of H3K27me3 and cell differentiation.

description: In the present study, we analyze the radial velocity distribution as a function of different stellar parameters such as stellar age, mass, rotational velocity and distance to the Sun for a sample of 6781 single low--mass field dwarf stars, located in the solar neighborhood. We show that the radial velocity distributions are best fitted by $q$--Gaussians that arise within the Tsallis nonextensive statistics. The obtained distributions cannot be described by the standard Gaussian that emerges within Boltzmann-Gibbs (B--G) statistical mechanics. The results point to the existence of a hierarchical structure in phase space, in contrast to the uniformly occupied phase space of B--G statistical mechanics, driven by the $q$--Central Limit Theorem, consistent with nonextensive statistical mechanics.

description: Modern JavaScript engines that power websites and even full applications on the Web are driven by the need for an increasingly fast and snappy user experience. These engines use several complex and potentially error-prone mechanisms to optimize their performance. Unsurprisingly, the inevitable complexity results in a huge attack surface and various types of software vulnerabilities. On the defender’s side, fuzz testing has proven to be an invaluable tool for uncovering different kinds of memory safety violations. Although it is difficult to test interpreters and JIT compilers in an automated way, recent proposals for input generation based on grammars or target-specific intermediate representations helped uncovering many software faults. However, subtle logic bugs and miscomputations that arise from optimization passes in JIT engines continue to elude state-of-the-art testing methods. While such flaws might seem unremarkable at first glance, they are often still exploitable in practice. In this paper, we propose a novel technique for effectively uncovering this class of subtle bugs during fuzzing. The key idea is to take advantage of the tight coupling between a JavaScript engine’s interpreter and its corresponding JIT compiler as a domain-specific and generic bug oracle, which in turn yields a highly sensitive fault detection mechanism. We have designed and implemented a prototype of the proposed approach in a tool called Jit-Picker. In an empirical evaluation, we show that our method enables us to detect subtle software faults that prior work missed. In total, we uncovered 32 bugs that were not publicly known and received a $10.000 bug bounty from Mozilla as a reward for our contributions to JIT engine security.

description: The complexity of modern processor architectures has given rise to sophisticated interactions among their components. Such interactions may result in potential attack vectors in terms of side channels, possibly available to userland exploits to leak secret data. Exploitation and countering of such side channels requires a detailed understanding of the target component. However, such detailed information is commonly unpublished for many CPUs. In this paper, we introduce the concept of Leakage Templates to abstractly describe specific side channels and identify their occurrences in binary applications. We design and implement PLUMBER, a framework to derive the generic Leakage Templates from individual code sequences that are known to cause leakage (e.g., found by prior work). PLUMBER uses a combination of instruction fuzzing, instructions' operand mutation and statistical analysis to explore undocumented behavior of microarchitectural optimizations and derive sufficient conditions on vulnerable code inputs that if hold can trigger a distinguishing behavior. Using PLUMBER we identified novel leakage primitives based on Leakage Templates (for ARM Cortex-A53 and -A72 cores), in particular related to previction (a new premature cache eviction), and prefetching behavior. We show the utility of Leakage Templates by re-identifying a prefetcher-based vulnerability in OpenSSL 1.1.0g first reported by Shin et al. [40].

description: For a graph G, a subset S ⊆ V (G) is called a resolving set if for any two vertices u, v ∈ V (G), there exists a vertex w ∈ S such that d(w, u) ̸= d(w, v). The Metric Dimension problem takes as input a graph G and a positive integer k, and asks whether there exists a resolving set of size at most k. This problem was introduced in the 1970s and is known to be NP-hard [GT 61 in Garey and Johnson’s book]. In the realm of parameterized complexity, Hartung and Nichterlein [CCC 2013] proved that the problem is W[2]-hard when parameterized by the natural parameter k. They also observed that it is FPT when parameterized by the vertex cover number and asked about its complexity under smaller parameters, in particular the feedback vertex set number. We answer this question by proving that Metric Dimension is W[1]-hard when parameterized by the feedback vertex set number. This also improves the result of Bonnet and Purohit [IPEC 2019] which states that the problem is W[1]-hard parameterized by the treewidth. Regarding the parameterization by the vertex cover number, we prove that Metric Dimension does not admit a polynomial kernel under this parameterization unless NP ⊆ coNP/poly. We observe that a similar result holds when the parameter is the distance to clique. On the positive side, we show that Metric Dimension is FPT when parameterized by either the distance to cluster or the distance to co-cluster, both of which are smaller parameters than the vertex cover number.

description: Simulation technologies a future, best for the acquisition of practical skills, abilities and knowledge, based on realistic modeling and simulation of the clinical situation using a variety of modern training equipment. Mastering and practicing skills during classes allows future doctors to more thoroughly prepare the student for further independent activity, compared with the theoretical analysis of the clinical situation, especially for students of foreign nationals. The simulation class is divided into such stages: initial assessment of students' knowledge, theoretical examination of skills, simulation training, debriefing, final testing and anonymous questionnaires. A checklist has been developed to objectively assess a particular skill or clinical scenario. Practical traini ng gives students the opportunity to work out the algorithm of actions in a specific clinical situation; optimize teamwork and clearly distribute team responsibilities. Thus, the use of simulation technologies in medicine increases students' interest in the learning process and is an important part in improving the professionalism of future doctors

description: Several visualization schemes have been developed for imaging materials at the atomic level through atom probe tomography. The main shortcoming of these tools is their inability to parallel process data using multi-core computing units to tackle the problem of larger data sets. This critically handicaps the ability to make a quantitative interpretation of spatial correlations in chemical composition, since a significant amount of the data is missed during subsequent analysis. In addition, since these visualization tools are not open-source software there is always a problem with developing a common language for the interpretation of data. In this contribution we present results of our work on using an open-source advanced interactive visualization software tool, which overcomes the difficulty of visualizing larger data sets by supporting parallel rendering on a graphical user interface or script user interface and permits quantitative analysis of atom probe tomography data in real time. This advancement allows materials scientists a codesign approach to making, measuring and modeling new and nanostructured materials by providing a direct feedback to the fabrication and designing of samples in real time.

description: We analyze theoretically the problem of cargo transport along microtubules by motors of two species with opposite polarities. We consider two different one-dimensional models previously developed in the literature. On the one hand, a quite widespread model which assumes equal force sharing, here referred to as mean field model (MFM). On the other hand, a stochastic model (SM) which considers individual motor-cargo links. We find that in generic situations the MFM predicts larger cargo mean velocity, smaller mean run time and less frequent reversions than the SM. These phenomena are found to be consequences of the load sharing assumptions and can be interpreted in terms the probabilities of the different motility states. We also explore the influence of the viscosity in both models and the role of the stiffness of the motor-cargo links within the SM. Our results show that the mean cargo velocity is independent of the stiffness while the mean run time decreases with such a parameter. We explore the case of symmetric forward and backward motors considering kinesin- 1 parameters, and the problem of transport by kinesin-1 and cytoplasmic dyneins considering two different sets of parameters previously proposed for dyneins.

description: В статье рассматриваются альтернативные методы создания архитектурной утопии. Автор придумывает технологию игрового предсказания города. В основе неё лежат принципы интерактивности, многовариативности и виртуальности. Главным элементом игрового метода предсказания является человек. Он превращается в игрока внутри виртуального города и может своими действиями менять его конфигурацию и форму. В основе такого подхода лежит идея живого действия — человек играет в будущее, а не предсказывает его. Таким образом, игрок не стремится создать одну единственную красивую версию будущего, а придумывает интерактивный мир. В финале автором представлена концепция игровой теории прогнозирования — архитектурная компьютерная игра. Архитектурная компьютерная игра — это многовариантный, интерактивный метод предсказания города будущего. В статье были выявлены следующие её принципы: управляемость (игрок может её контролировать); масштабируемость (игрок может настраивать игру под себя); условность (игрок понимает разницу между реальным миром и виртуальным); прерываемость (игрок в любой момент может отключить игру). Современная теория прогнозирования выполняет функцию интерактивного предвидения (игры), заменяя тем самым статичное состояние утопии (идеальная модель). Она становится мощным генератором вариантов, возникающих лишь в момент попадания человека внутрь игровой системы. Взаимодействие человека с миром будущего становится основополагающим принципом новой методологии прогнозирования, которая позволяет не только создавать фантастический город, но и играть в него.

description: One of the open problems in machine learning is whether any set-family of VC-dimension d admits a sample compression scheme of size O(d). In this paper, we study this problem for balls in graphs. For balls of arbitrary radius r, we design proper sample compression schemes of size 4 for interval graphs, of size 6 for trees of cycles, and of size 22 for cube-free median graphs. We also design approximate sample compression schemes of size 2 for balls of δ-hyperbolic graphs.

description: We study the motion of an elastic object driven in a disordered environment in presence of both dissipation and inertia. We consider random forces with the statistics of random walks and reduce the problem to a single degree of freedom. It is the extension of the mean field ABBM model in presence of an inertial mass m. While the ABBM model can be solved exactly, its extension to inertia exhibits complicated history dependence due to oscillations and backward motion. The characteristic scales for avalanche motion are studied from numerics and qualitative arguments. To make analytical progress we consider two variants which coincide with the original model whenever the particle moves only forward. Using a combination of analytical and numerical methods together with simulations, we characterize the distributions of instantaneous acceleration and velocity, and compare them in these three models. We show that for large driving velocity, all three models share the same large-deviation function for positive velocities, which is obtained analytically for small and large m, as well as for m =6/25. The effect of small additional thermal and quantum fluctuations can be treated within an approximate method.

description: В статье автор анализирует современные теории в отношении концепции времени и способов представления будущего. Он приходит к выводу, что само понятие времени не универсально и относительно. Это неминуемо ставит вопрос о роли и функции архитектурной утопии и влечет за собой поиск новых игровых моделей прогнозирования будущего. В рамках данной идеи был введён новый концептуальный термин в области архитектурной утопии «параллельная реальность». Параллельная реальность это игровое пространство, которое использует разнообразные типы времени и стремится создать живой архитектурный мир будущего. Автор обращается к различным технологиям путешествия во времени, в проекте параллельной реальности, для исследования игровых методов прогнозирования будущего. В результате, им были предложены три типа «прыжка во времени»: прыжок в будущее, прыжок в прошлое и мультипрыжок. В финале автор переосмысляет сам подход к прогнозированию будущего, который неминуемо имеет свой концептуальный предел или горизонт предвидения. Гипотеза о параллельной реальности, по мнению автора, способна преодолеть гравитацию этого предела и выйти за рамки привычных нам образов и способов мышления о будущем.
The work of deans of medicine

description: This dissertation studies the work done by deans of medicine as agents in the field of academic medicine. In this study, I use Pierre Bourdieu's theory of field-habitus-capital to examine how the field of academic medicine developed in Canada and how the position of dean of medicine emerged within that field. I interviewed 14 current and past deans of Canadian medical schools. In addition, I interviewed several faculty members, senior university administrators and one other physician executive who was not affiliated with a medical school. The interviews were semi-structured, lasted anywhere from 60 to 90 minutes and were mostly by telephone. Canada's earliest medical schools were a combination of university and non-university proprietary schools. Academic medicine in Canada began at McGill University in the early nineteenth century. The position of dean of medicine emerged in the mid-nineteenth century in Canada. Initially the person who was called a dean of medicine was often the oldest physician in the group. By the end of the nineteenth century, academic medicine was well established in Canada's two largest provinces - Quebec and Ontario - and a McGill habitus had emerged. Today, a dean of medicine is a dominant position in the health and academic fields. Social capital - the capital of social connections and obligation - plays an important role in bringing a deanship to some players rather than others. Those physicians who have been a department head, especially of internal medicine, or those physicians who were mentored by a previous dean, appear to be more likely to become dean of medicine. Mastering strategies of obsequiousness - knowing one's place and modesty about accomplishments - nepotism and team spirit are important for success in the field. During the search and selection process, displaying a habitus that shows the candidate has a well-developed feel for the game is important for success and how the candidate expresses a vision for the future of the faculty is the principal way in which this decanal habitus is demonstrated. Much of a dean's work has to do with managing crises that threaten the faculty. The search for economic capital is their consistent preoccupation. Overall, becoming a dean of medicine appears to be a matter of fulfilling a destiny in the field.

description: Silicon carbide (SiC) is a ceramic with strength retention at elevated temperatures, oxidation resistance and a high thermal conductivity. These properties make SiC a desirable ceramic for compact, high temperature (> 1000 °C), heat exchangers with improved thermal performance. However, fabricating a SiC heat exchanger is difficult due to the low self-diffusion and high melting temperature of SiC. The aim of this dissertation is to show the viability of using co-extrusion and slip casting as low-cost, scalable processes for creating a compact, high temperature, SiC heat exchanger.Co-extrusion is an advantageous fabrication technique as it is capable of producing samples with micron-sized features in two dimensions. To fabricate the heat exchanger body via co-extrusion, a SiC-filled polymer blend and a carbon black (CB)-filled polymer blend (sacrificial) were developed. A 54 vol% SiC-filled polymer blend with the addition of 12 wt% alumina and yttria, sintering aids, in a 2:1 ratio, respectively produced samples with the highest relative densities of 94% while maintaining an extrudable rheology. The SiC-filled polymer blend was co-extruded at 80 °C with a 45 vol% CB-filled polymer blend to produce unit cells that were open and continuous after binder burnout and sintering. The unit cells had an average relative density of 90% with an average strength of 165 MPa.The unit cell strengths were lower than expected due to the formation of defects that occurred after removal of the polymers. These defects were categorized into macrodelaminations, defects that occur between two laminated unit cells, and microdelaminations, defects that occur within a single unit cell. The mechanisms causing these defects was studied by investigating the lamination and polymer removal processes. Results showed that poor lamination between extrudates mitigated the macrodelaminations and an oxygen-rich debinding atmosphere caused the formation of microdelaminations. Defect-free unit cells were produced though a partial extrusion step and binder removal in a nitrogen atmosphere.An aqueous SiC suspension for slip casting was optimized by investigating the rheological properties, zeta potential, and slip casting behavior. It was determined that a suspension with 40 vol% solids, 1.2 wt% dispersant (polyethyleneimine), and a pH of 7.5 resulted in uniform slip cast parts. This optimized suspension was used to fabricate dense, crack-free SiC headers with an average relative density of 96% and an average strength of 266 MPa.This dissertation gives insight into important fabrication parameters that must be considered when fabricating high temperature, SiC heat exchanger components. Additionally, this dissertation showcases the capability of using co-extrusion and slip casting as potential pathways for fabricating a high temperature, SiC heat exchanger.

description: We propose leakage containment models (LCMs)—novel axiomatic security contracts which support formally reasoning about the security guarantees of programs when they run on particular microarchitectures. Our core contribution is an axiomatic vocabulary for formalizing LCMs, derived from the established axiomatic vocabulary for formalizing processor memory consistency models. Using this vocabulary, we formalize microarchitectural leakage—focusing on leakage through hardware memory systems—so that it can be automatically detected in programs and provide a taxonomy for classifying said leakage by severity. To illustrate the efficacy of LCMs, we first demonstrate that our leakage definition faithfully captures a sampling of (transient and non-transient) microarchitectural attacks from the literature. Second, we develop a static analysis tool based on LCMs which automatically identifies Spectre vulnerabilities in programs and scales to analyze real-world crypto-libraries.

description: During Kraft pulping, cellulose fibres are liberated from a lignin-matrix, found in a wood chip, by reaction at elevated temperature and pressure using an alkaline solution. Poor lignin removal is a deleterious effect that leads to downstream operational difficulties and decreased product quality. A number of research groups speculate that this is caused by the uneven distribution of the alkaline solution through the wood chip bed during reaction. As a result, the goal of this thesis is to characterize the ease by which fluid flows, and disperses, through wood chip beds. One of the open remaining scientific questions is understanding the effect of bed compressibility on the resulting flow patterns. In the first portion of this work we present a methodology to characterize the permeability of a compressible bed of wood chips under mechanical load. We show that under the limiting condition of when the mechanical load is large in comparison to hydraulic pressure the equations of motion can be linearized and solved to produce an expression approximating the variation in porosity along the length of the bed. We show how this may be used, in conjunction with multiple linear regression, to estimate permeability of the bed. The usefulness of these estimates was then tested by predicting the pressure drop versus flow relationship for conditions outside the range of the linearized solution. Good agreement was obtained. In the second portion of this work we present a methodology to characterize the axial dispersion of a solute during steady-flow through a compressible bed of wood chips under mechanical load. We use a non-invasive imaging technique, namely electrical resistance tomography (ERT), to visualize the uniaxial displacement of a salt solution. Here we demonstrate that under two limiting cases the porosity of the porous bed varies slowly in the flow-direction and to the lowest order can be considered a constant. This simplified the optimization routine we used to match the experimental data to the numerical results of the advection-diffusion equation. Using this, a methodology to estimate the axial dispersion is given by a minimization scheme.

description: Sizable amount of heavy-quarkonium events can be produced through $W$-boson decays at the LHC. Such channels will provide a suitable platform to study the heavy-quarkonium properties. The "improved trace technology", which disposes the amplitude ${\cal M}$ at the amplitude-level, is helpful for deriving compact analytical results for complex processes. As an important new application, in addition to the production of the lower-level Fock states $|(Q\bar{Q'})[1S]>$ and $|(Q\bar{Q'})[1P]>$, we make a further study on the production of higher-excited $|(Q\bar{Q'})>$-quarkonium Fock states $|(Q\bar{Q'})[2S]>$, $|(Q\bar{Q'})[3S]>$ and $|(Q\bar{Q'})[2P]>$. Here $|(Q\bar{Q'})>$ stands for the $|(c\bar{c})>$-charmonium, $|(c\bar{b})>$-quarkonium and $|(b\bar{b})>$-bottomonium respectively. We show that sizable amount of events for those higher-excited states can also be produced at the LHC. Therefore, we need to take them into consideration for a sound estimation.

description: В статье автор предлагает отказаться от классического определения будущего. Сегодня можно говорить о том, что любые методы исследования будущего, основанные на человеческих способах мышления, устаревают. Будущее ускользает от нашего понимания, как от субъекта. Теперь уже само будущее становится субъектом, который смотрит и говорит с человеком, как с объектом. Будущее — это незнакомый нам Другой. В ходе этого концептуального поворота в современной мысли, архитектура отказывается от создания образа будущего и стремится к проектированию живых осознанных игровых реальностей. То есть, проектирует виртуального Другого. Для этого, архитектурная утопия XXI-го века использует альтернативные теории о времени, которые определяют будущее не как «космологическую», «единую» и «идеальную» систему, а как многовариантную и интерактивную модель, или как (ксено)-субъект. Можно говорить о том, что будущее впервые обретает свою виртуальную ксено-субъектность. Другими словами, сегодня архитектор создаёт не умозрительное будущее, а параллельный нашему игровой мир, по типу разумной компьютерной игры. В такой архитектурной компьютерной игре архитектор может не только находиться, но и жить, становиться героем своего же города будущего и вступать с ним в диалог. В финале, автор вводит гипотезу о ксеноутопии, в качестве ультрасовременной модели интерактивного архитектурного будущего.

description: We present results of an exclusive measurement of the first excited state of the Sigma hyperon, Sigma(1385)^+, produced in p+p -> Sigma^+ + K^+ + n at 3.5 GeV beam energy. The extracted data allow to study in detail the invariant mass distribution of the Sigma(1385)^+. The mass distribution is well described by a relativistic Breit-Wigner function with a maximum at m_0 = 1383.2 +- 0.9 MeV/c^2 and a width of 40.2 +- 2.1 MeV/c^2. The exclusive production cross-section comes out to be 22.27 +- 0.89 +- 1.56 +3.07 -2.10 mu b. Angular distributions of the Sigma(1385)^+ in different reference frames are found to be compatible with the hypothesis that 33 % of Sigma(1385)^+ result from the decay of an intermediate Delta^{++} resonance.

description: Laser trapping and interfacing of laser-cooled atoms in an optical fiber network is an important capability for quantum information science. Following the pioneering work of Balykin et al. and Vetsch et al., we propose a robust method of trapping single Cesium atoms with a two-color state-insensitive evanescent wave around a dielectric nanofiber. Specifically, we show that vector light shifts (i.e., effective inhomogeneous Zeeman broadening of the ground states) induced by the inherent ellipticity of the forward-propagating evanescent wave can be effectively canceled by a backward-propagating evanescent wave. Furthermore, by operating the trapping lasers at the magic wavelengths, we remove the differential scalar light shift between ground and excited states, thereby allowing for resonant driving of the optical D2 transition. This scheme provides a promising approach to trap and probe neutral atoms with long trap and coherence lifetimes with realistic experimental parameters.
