Authoring Tools for FreePlay Simulation-Based Troubleshooting Training

All training systems require definition of curriculum and creation of associated instructional materials. Simulationbased training systems further require development (or at least integration) of a suitable simulation environment, and specification of challenge problems. Intelligent tutoring systems (ITSs), in addition, require logic for automated assessment, student/tutor interaction, and experience sequencing. Costs to create all these pieces can mount quickly, so it is important to provide authoring tools tied to general methods and code to speed content creation, reduce required levels of authoring expertise, and facilitate reuse. This paper reports on authoring tool development and preliminary evaluation in the context of a simulation-based ITS employing novel mechanisms for tutoring troubleshooting skills. Major challenges included: (1) defining the data needs of the ITS, given it is neither a rule-driven cognitive tutor, nor an example tracing tutor; (2) mapping the system’s complex data structures to consistent, supportive, tailorable user interface conventions so as to enhance tool usability and maintainability; (3) bridging between the desired unified authoring tool suite and useful commercial off-the-shelf (COTS) tools—e.g., for didactic instruction and simulation; and (4) designing for flexibility, so as to track evolution of the underlying tutor mechanisms and enable future generalization. The example ITS trains Navy Information Systems Technicians to carry out troubleshooting and procedure-following tasks using virtualized computer networks as a free-play simulation environment. The tutor adds simulation instrumentation to gather information that feeds models of available actions and resulting states of knowledge. It then monitors student activity, hypotheses, and inferences, so as to provide contextualized, adaptive feedback and coaching. The project was concerned with establishing a general framework for simulation-based technology troubleshooting applications, and had strong requirements for broad-spectrum authoring tools. We describe the project context, tutoring approach, authoring tools developed, authoring evaluation feedback, relationship to other authoring tool efforts, and lessons learned.
High Accuracy Time Domain Modeling of Microstrip Discontinuities by Using Modified TDR Based on Barker Codes with Flat Spectrum and Integrated Side-Lobes

─ In this paper, a novel time domain method by using a modified time domain reflectometry is presented for high accuracy modeling of microstrip discontinuities. The ordinary stimulus signals used in the TDR technique are voltage step or voltage impulse. In this paper, we propose an alternative technique, whereby a modified excitation pulse based on Barker-Code orthogonal pulses is employed as the stimulus signal in TDR. The advantage conferred by “Barker codes TDR” is that more energy is available at higher frequencies in contrast with conventional step or impulse TDR, and so a higher bandwidth and higher accuracy of the line impedance is achieved. It can also be advantageous when the user is looking for precision in spatial localization, say in a connector or similar in-line structure, as the increased energy at higher frequencies can help. Simulated results are presented to validate the usefulness of the proposed method for calculating the precise amount of time-dependent equivalent circuit of microstrip discontinuity. Index Terms ─ Finite difference time domain (FDTD), microstrip discontinuity, time domain reflectometry (TDR), and time domain modeling.

On a social impact front, this study provides the technical backbone for a media campaign aimed at raising public and deciders’ awareness and elevating the standards expected from social media companies.
Mental Deficiency Etiology in Brazilian Populations View project Sickle Cell Disease and Stroke View project

Mitochondrial dysfunction is regarded as a hallmark of cancer progression. In the current study, we evaluated mitochondrial genome instability and copy number in colorectal cancer using Next Generation Sequencing approach and qPCR, respectively. The results revealed higher levels of heteroplasmy and depletion of the relative mtDNA copy number in colorectal adenocarcinoma. Adenocarcinoma samples also presented an increased number of mutations in nuclear genes encoding proteins which functions are related with mitochondria fusion, fission and localization. Moreover, we found a set of mitochondrial and nuclear genes, which cooperate in the same mitochondrial function simultaneously mutated in adenocarcinoma. In summary, these results support an important role for mitochondrial function and genomic instability in colorectal tumorigenesis.
Treatment of Eye Infections

The quinolone antimicrobials are commonly prescribed as eye drops for the therapy of anterior eye infections such as conjunctivitis and keratitis. Ophthalmic drops containing 3 mg of norfloxacin, ciprofloxacin, ofloxacin, and levofloxacin per ml (0.3% solutions) are available. Bacterial infections of the eye and contiguous tissues include conjunctivitis, keratitis, blepharitis, preseptal cellulitis, orbital cellulitis, cavernous sinus thrombosis, uveitis, and endophthalmitis. The discussion in this chapter is limited to the use and pharmacology of quinolones for the treatment of bacterial infections of the conjunctiva (conjunctivitis), cornea (keratitis), and aqueous and vitreous humors (endophthalmitis). Conjunctivitis is the most common bacterial infection of the eye and is also often caused by viruses. Although it causes local symptoms including irritation and tearing, it is rarely sight threatening and often resolves without antimicrobial therapy. Treatment of keratitis requires antibiotic penetration into the corneal stroma, and endophthalmitis requires penetration into the aqueous and vitreous humors. Pharmacodynamic models characterize the relationship between antimicrobial drug exposure and activity, expressed as the MIC, with efficacy or drug exposure with toxicity. The pharmacokinetics of intravitreal quinolones has been characterized for fleroxacin, ciprofloxacin, ofloxacin, and sparfloxacin. Lipophilic quinolones such as ofloxacin, levofloxacin, and sparfloxacin show good penetration into the vitreous humor following systemic drug administration even in the absence of inflammation.
Conservation Agreements: Relational Contracts with Endogenous Monitoring

Author(s): Gjertsen, Heidi; Groves, Theodore; Miller, David A; Niesten, Eduard; Squires, Dale; Watson, Joel | Abstract: Abstract This article examines the structure and performance of conservation agreements, which are relational contracts used across the world to protect natural resources. Key elements of these agreements are (1) they are ongoing arrangements between a local community and an outside party, typically a nongovernmental organization (NGO); (2) they feature payments in exchange for conservation services; (3) the prospects for success depend on the NGO engaging in costly monitoring to detect whether the community is foregoing short-term gains to protect the resource; (4) lacking a strong external enforcement system, they rely on self-enforcement; and (5) the parties have the opportunity to renegotiate at any time. A repeated-game model is developed and utilized to organize an evaluation of real conservation agreements, using three case studies as representative examples. (JEL D74, D86, Q20, Q56)
Ethics and Aesthetics in the Production of Sense in Early Childhood : A Reflection on the Simultaneity of the Past and Future in the Present / Ética

In this study, we explored some theoretical assumptions of literary analysis within the context of everyday situations of sense production. This operation was carried out by analyzing longitudinal videotaped sessions of the interactions between a mother and an infant. Concepts related to language, ethics and aesthetics formed the basis for the theoretical assumptions that guided our analysis. A microanalysis of empirical data illustrates the functioning of these assumptions for the production of sense. In the results, we discussed the implications of the simultaneity of past experiences and the anticipation of future possibilities for the organization of the actions in the immediate present. We concluded that the production of sense is a way to solve emerging tensions related to the simultaneity of past and future, originality, individuality, and dynamic stability when responsive situations arise. Therefore, the production of sense was considered an ethical and aesthetic human action, and we were able to verify how appropriate these assumptions were to analyze language practices outside literature.

2018 년 한국컴퓨터종합학술대회 논문집 Server Provisioning and User Association in Multi-Site Multi-access Edge Computing

Multi-access Edge Computing (MEC) is recently profound for the next revolution of mobile communications area, where the convergence of IT and telecommunications networking provides lower latency and more computation capability for cellular base stations. In this paper, we formulate a novel optimization problem for server provisioning and user association to enhance the performance of the network operator in terms of energy cost and the average delay of mobile users. The problem is relaxed and approximately solved by an iterative algorithm and converge to a suboptimal solution of the original problem.
Some Remarks on Certain Types of Continuity 141

Infinite matrix transformation theory plays an important role in analysis, specially on the theory of summability. In this paper we introduce the concept of A− continuity of a real valued function associated with a regular infinite matrix A and some result related to A−continuous function has been established. Also a characterization of A−continuous function is presented after introducing the notion of A− oscillation of a function.
TOTAL WAX AND N-ALKANE PROFILES FROM FRUIT AND LEAF WAXES OF MALPIGHIA GLABRA L

(Total wax and p/alkane profi les from fruit and leaf waxes of Ocnrkijkc"incdtc"L.) Ocnrkijkc"incdtc"L. , popularly known as “acerola” or Barbados cherry, is an economically important species due the high levels of ascorbic acid (vitamin C) in its fruits. Cuticular wax affects post-harvest storage. Nevertheless, no data are available for wax composition on this species. Crude wax amount and p-alkane profi les have been evaluated for three distinct genotypes of acerola. The total amount of wax ranged from 11 μg. cm-2 to 24 μg. cm-2 on leaves and 10 μg. cm-2 to 30 μg. cm-2 on fruits. Two of the three genotypes presented statistically distinct totals for leaf and fruit-wax. Type A (yellow epicarp) presented the highest amounts of crude wax on both leaves and fruits. p/Alkanes ranged from C18 to C34 in fruits, with p/pentacosane (C25) as the main homologue of most individuals. Narrower p/alkane distribution was found in cuticular foliar wax, with C22-C33, with p/ hentriacontane (C31) as the major component of most individuals. The environmental and economical aspects related to total wax amounts and p/alkane profi les are discussed herein. Resumo (Cera total e perfi l dos p-alcanos de frutos e folhas de Ocnrkijkc"incdtc"L.) Ocnrkijkc"incdtc"L. , conhecida popularmente como acerola, é uma espécie economicamente importante devido ao elevado nível de ácido ascórbico (vitamina C) em seus frutos. A cera cuticular afeta o armazenamento do fruto pós-colheita. No entanto, não há dados disponíveis sobre a composição das ceras nessa espécie. Teor de cera total e perfi l de p-alcanos foram estudados em três genótipos diferentes de acerola. A quantidade de cera total variou de 11 μg. cm-2 a 24 μg. cm-2 nas folhas e nos frutos de 10 μg. cm-2 a 30 μg. cm-2. Dois dos três genótipos apresentaram diferenças signifi cativas entre os teores de cera dos frutos e das folhas. O tipo A (epicarpo amarelo) apresentou a maior quantidade de cera tanto nas folhas como nos frutos. O perfi l de p-alcanos nos frutos variou de C18-C34, sendo p-pentacosano (C25) o homólogo principal na maioria dos indivíduos. A cera cuticular foliar apresentou um perfi l de p-alcanos com distribuição mais restrita, com os homólogos C22-C33 como componentes majoritários. Os homólogos de cadeia curta foram detectados sempre em quantidades menores do que 1%. O p-hentriacontano (C31) foi o p-alcano principal na cera foliar. Implicações econômicas e ecológicas relacionadas à quantidade das ceras cuticulares e ao perfi l de p-alcanos são discutidas.
400 GbE Technology Demonstration Using CFP 8 Pluggable Modules

In this article, we first review the current status of 400GBASE client-side optics standards and multi-source agreements (MSAs). We then compare different form factors for 400GE modules, including CFP8, OSFP and QSFP-DD. The essential techniques to implement 400GE, such as pulse amplitude modulation (PAM4), forward error correction (FEC) and a continuous time-domain linear equalizer (CTLE), are discussed. A 400GE physical interface card (PIC) in Juniper’s PTX5000 platform has been developed, conforming to the latest IEEE802.3bs standard. To validate the PIC’s performance, a commercial optical network tester (ONT) and the PIC are optically interconnected through two CFP8-LR8 modules. The CFP8-LR8 module utilizes eight optical wavelengths through coarse wavelength division multiplexing (CWDM). Each wavelength carries 50 Gb/s PAM4 signal. The signal transmits through 10 km of single mode fiber (SMF). The ONT generates framed 400GE signal and sends it to the PIC through the first CFP8 module. The PIC recovers the signal, performs an internal loopback, and sends 400GE signal back to the ONT through the second CFP8 module. The optical spectrum, eye diagram, receiver sensitivity, long time soaking results, and internal digital diagnosis monitoring (DDM) result are fully characterized. The pre-FEC bit error rate (BER) is well below the KP4 FEC threshold of 2.2 × 10−4. After KP4 FEC, error-free performance over 30 km of SMF is achieved. In this way, we demonstrate both the interoperation between the PIC and the ONT, as well as the interoperation between the two CFP8 modules. This demonstration represents the successful implementation of the 400GE interface in the core IP/MPLS router.

UI Redressing Attacks on Android Devices

In this paper, we describe novel high-impact user interface attacks on Android-based mobile devices, additionally focusing on showcasing the possible mitigation techniques for such attacks. We discuss which UI redressing attacks can be transferred from desktopto mobilebrowser field. Our main contribution is a demonstration of a browserless tap-jacking attack, which greatly enriches the impact of previous work on this matter. With this technique, one can perform unauthorized home screen navigation and attempt actions like (premium number) phone calls without having been granted appropriate privileges. To protect against this attack, we introduce a concept of a security layer that catches all tapjacking attempts before they can reach home screen/arbitrary applications.
Fast Finite-Difference Calculation of Eddy Currents in Thin Metal Sheets

─ Magnetic excitation of eddy currents in a thin metal sheet is a difficult problem that has many useful applications to scrap metal recycling. Using finitedifference approximations on both the curl and divergence of the current density, we develop a numerical algorithm that is simple to implement, quick to solve, and capable of modeling excitation from arbitrary magnetic field distributions. For the special case of a weakly-induced eddy field, the self-inductance terms can be neglected, resulting in a sparse system matrix that is easily inverted. For a strongly-induced eddy field, self-inductance must be included at the cost of a more complex, denser system matrix. The method is validated against the CST EM Studio software suite and produces nearly identical results on a thin-sheet simulation in only a tiny fraction of the time. Index Terms ─ Current density, eddy currents, finitedifference method, quasistatics.
FIELD GUIDE TO THE LEMHI ARCH AND MESOZOIC-EARLY CENOZOIC FAULTS AND FOLDS IN EAST-CENTRAL IDAHO : BEAVERHEAD MOUNTAINS

This field trip wi ll focus on a portion of the Rodinian rift margin on the western edge of Laurentia where Neoproterozoic to Lower Ordovician synand early post-rift clastic sedimentary rocks are absent. This region of missing stratigraphy, called the Lemhi arch, is in east-central Idaho, is roughly northwest-trending, and contains a belt of Cryogen ian and Late Cambrian alkalic plutons (e.g., Lund and others, 201 0). This region of thin or absent Neoproterozoic and lower Paleozoic strata con·elates spatially with the boundary between. the_n_orthem. Wyoming salientand southwest Montana reentrant of the Mesozoic to early Cenozoic SevierLaramide fold-thrust belt (Armstrong, 1975) and likely influenced the transition from thinto thickskinned thrusting.
New Findings on Anti-Mullerian Hormone in Polycystic Ovarian Syndrome Patients

Polycystic Ovarian Syndrome (PCOS) is the most complex and common endocrine disorders in women, associated with a wide range of symptoms such as, irregular menstrual cycle, acne, hirsutism and weight gain. Despite extensive research, the pathogenesis of the disease is not known yet. Genetic, endocrine and environmental factors have been discussed in the pathogenesis of PCOS. Compared with the general population, PCOS patients are at a greater risk of uterine cancer, cardiovascular problems and metabolic complications. Each of these issues may lead to death. However; Anti-Mullerian Hormone (AMH) is a unique biomarker of ovarian function in assessment of women’s health. In addition, this can be used in treatment of infertility. It is argued that the amount of AMH in women with PCOS is more than normal but the cause of this increase has not been identified yet. Therefore, more research is needed to understand the role of this hormone in the pathophysiology of PCOS and its relationship with other factors. In this study findings regarding the anti-Mullerian hormone and polycystic ovary syndrome are reviewed.
A Proximity-Based Early Warning System for Gentrification in California Aakash Pattabi

With the recent failure of Senate Bill (SB) 827 in California, pressure is higher than ever on state politicians to better understand and respond to the increasing unaffordability of California’s urban centers. Designed to issue more housing construction permits in high-opportunity areas, SB 827 was ironically crippled by its failure to explicitly acknowledge the possible gentrification externalities of new housing construction. Because of the astronomical (and increasing) cost of housing, more Californians live in poverty than in any other state when cost of living is accounted for [6]. It is imperative that California’s policymakers articulate smart housing policies that do not lock out access to the state’s economic engines to the neediest Californians.
Is VIP 1 important for Agrobacterium-mediated transformation ?

Agrobacterium genetically transforms plants by transferring and integrating T-(transferred) DNA into the host genome. This process requires both Agrobacterium and host proteins. VirE2 interacting protein 1 (VIP1), an Arabidopsis bZIP protein, has been suggested to mediate transformation through interaction with and targeting of VirE2 to nuclei. We examined the susceptibility of Arabidopsis vip1 mutant and VIP1 overexpressing plants to transformation by numerous Agrobacterium strains. In no instance could we detect altered transformation susceptibility. We also used confocal microscopy to examine the subcellular localization of Venus-tagged VirE2 or Venus-tagged VIP1, in the presence or absence of the other untagged protein, in different plant cell systems. We found that VIP1–Venus localized in both the cytoplasm and the nucleus of Arabidopsis roots, agroinfiltrated Nicotiana benthamiana leaves, Arabidopsis mesophyll protoplasts and tobacco BY-2 protoplasts, regardless of whether VirE2 was co-expressed. VirE2 localized exclusively to the cytoplasm of tobacco and Arabidopsis protoplasts, whether in the absence or presence of VIP1 overexpression. In transgenic Arabidopsis plants and agroinfiltrated N. benthamina leaves we could occasionally detect small aggregates of the Venus signal in nuclei, but these were likely to be imagining artifacts. The vast majority of VirE2 remained in the cytoplasm. We conclude that VIP1 is not important for Agrobacterium-mediated transformation or VirE2 subcellular localization.
