History Of The European Conference Series On Digital Pathology: Memories And Perspectives
Creators: name: Kayser, Klaus
Publisher: name: Diagnostic Pathology
Year: 2016
Subjects: European Conference; Digital Pathology

description: The 13th European Congress on Digital Pathology is the most recent conference of a European Conference series that started in Heidelberg 26 years ago. It reflects to a continuous, unbroken exchange of technological and medical information. The digital world was still in its childhood at the date of the first conference. Technological research investigated in electronic communication and digital acquisition of coloured pictures. Frozen section services and its need for fast information transfer between different institutes and the surgical theatre dominated the application of technological development. Consecutively, all issues of telepathology were in focus at the start and the following conferences. The pioneers of that time tried to convince their colleagues of the promising perspectives and the increasing technological influence on pathology.

It took several conferences in this series until the majority of or nearly all pathologists recognized the power of this new technology.  Retrospectively, some conferences remained at the scientific level of their preceding meetings, whereas others substantially promoted knowledge and application in research and routine pathology.

At present, digital pathology is well implemented and mainly used for education and enhancement of molecular biology methods such as next generation sequencing, predictive diagnosis, or risk associated investigations. Implementation in routine diagnostic pathology (virtual slides, etc.) is on its way.

In addition, digital pathology moves forward to explore still unknown areas in surgical pathology, and tissue – based diagnosis. These include considerations on morphology, function and order of structures, which can detect potentially endangered factors or repair of live threatening breakdowns, as well as biostatistics, data mining, or self recognition algorithms.

Power-Law tailed statistical distributions and Lorentz transformations
Creators: name: Kaniadakis, G.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The present Letter, deals with the statistical theory [Phys. Rev. E {\bf 66}, 056125 (2002) and Phys. Rev E {\bf 72}, 036108 (2005)], which predicts the probability distribution $p(E) \propto \exp_κ (-I)$, where, $I \propto βE -βμ$, is the collision invariant, and $\exp_κ(x)=(\sqrt{1+ κ^2 x^2}+κx)^{1/κ}$, with $κ^2<1$. This, experimentally observed distribution, at low energies behaves as the Maxwell-Boltzmann exponential distribution, while at high energies presents power law tails. Here we show that the function $\exp_κ(x)$ and its inverse $\ln_κ(x)$, can be obtained within the one-particle relativistic dynamics, in a very simple and transparent way, without invoking any extra principle or assumption, starting directly from the Lorentz transformations. The achievements support the idea that the power law tailed distributions are enforced by the Lorentz relativistic microscopic dynamics, like in the case of the exponential distribution which follows from the Newton classical microscopic dynamics.

description: Loss of HLA function is known to be a common immune escape mechanism across many cancers. Despite this, studies investigating the molecular mechanisms underpinning this loss have been hindered by the extreme genetic polymorphism of the HLA genes. Modern computational methods for high-throughput sequence-based analyses often rely on a standard reference, which is a problem for the HLA genes where most individuals will be highly divergent from the HLA sequences found in the standard reference. In this dissertation I present three methods that solve this problem by departing from the standard reference paradigm in favor of dynamic reference selection, where each individual will be analyzed relative to a personalized set of HLA reference sequences. I first present Hapster, a genomics tool that uses DNA sequencing data to construct personalized genomic references for the HLA genes. I show that Hapster produces high quality reference sequences, and that somatic mutation calling relative to these references has higher sensitivity and specificity than existing methods. To demonstrate the utility of Hapster, I next applied it to 12,000 primary and metastatic cancers from the TCGA and MI-ONCOSEQ projects. I show that using Hapster, we were able to identify patterns of positive selection within squamous cell carcinomas, lymphomas, and cancers with microsatellite instability, and identify the likely mutational processes responsible for these mutations. I next present HLAProphet, a proteomics tool that uses known HLA types to provide personalized quantification of the HLA proteins. I show that HLAProphet’s protein quantification has higher correlation to paired RNA expression data than existing methods, and that allele specific expression values reflect known loss of function genomic events. Finally, I present MHConstruct, a graph-based genomics algorithm that produces personalized reconstructions of the entire 5 Mb MHC locus. I show that MHConstruct’s personalized reference sequences have rates of germline variation below the genome-wide average of 1 snp/kb, enabling analyses of the polymorphic intergenic regions containing the promoters, enhancers, and other regions that regulate the HLA genes. In total, the tools presented here allow for a complete personalized proteogenomic characterization of the HLAs, enabling more thorough investigations of loss of HLA function as an immune escape mechanism for cancers.

description: Based on a variant of 2-site Jaynes-Cummings-Hubbard model, which is constructed using superconducting circuits, we propose a method to coherently superpose the localized and delocalized phases of photons. In our model, two nonlinear superconducting stripline resonators are coupled by an interfacial circuit composed of parallel combination of a superconducting qubit and a capacitor, which plays the role of a quantum knob for the photon hopping rate: with the knob qubit in its ground/excited state, the injected photons tend to be localized/delocalized in the resonators. We show that, by applying a microwave field with appropriate frequency on the knob qubit, we could demonstrate Rabi oscillation between photonic localized phase and delocalized phase. Furthermore, this set-up offers advantages (e. g. infinite on/off ratio) over other proposals for the realization of scalable quantum computation with superconducting qubits.

Collaborative assessment in middle school mathematics

Publisher: name: University of British Columbia
Year: 2010

description: This study examined the mathematical learning that grade 8 students demonstrated when they were given the opportunity to work collaboratively, with a teacher-assigned partner, on an in-class assessment. In addition to topic-specific concepts, skills, and procedures, mathematical learning also included more general abilities such as selecting strategies, developing plans, communicating ideas, and evaluating solutions. The primary sources of data for this study were the conversations and written papers of four “equal status” dyads as they worked on a problemsolving assessment in which they were encouraged to discuss their ideas and submit a joint solution. Analysis indicated that most dyads worked collaboratively throughout the task and that both students were relatively equal contributors to the joint solution. Therefore, while collaborative assessment reduced the ability to hold individual students accountable for what they had learned, it appeared to be an accurate reflection of most students’ mathematical knowledge and ability. One dyad, however, remained committed to working independently; the partners rarely discussed their ideas with each other and both students created their own solutions. During their discussions, students who collaborated were more likely to discuss various calculations related to the problem, rather than discuss potential strategies or solutions. Students interacted comfortably and informally with each other and asked questions if they did not understand, but did not often critically challenge their partner’s suggestions or provide justification for their own ideas. As a result, students did not always make reasoned choices when approaching the problem or evaluate the appropriateness of their strategy or solution.
Release of uric acid from poly(ɛ-caprolactone) nanofibers as potential treatment for spinal cord injury
Creators: name: Khaliq, Salman
Publisher: name: No Publisher Supplied
Year: 2020

description: Spinal cord injury (SCI) is characterized by two phases: the primary phase involves a traumatic event, which can be external or internal injury, and a secondary phase, which entails a number of biochemical processes, eventually resulting in inflammation, neuronal death, and axonal demyelination. Glutamate-induced excitotoxicity (GIE) is the major contributor to this secondary SCI pathway. GIE is mediated by the release of excessive glutamate into synaptic clefts, overstimulating N-methyl-D-aspartate channels, which increases intracellular Ca2+, and results in cell swelling and mitochondrial dysfunction. Furthermore, GIE increases the production of toxic reactive species, leading to DNA and mitochondrial damage, and eventually, cell death. Currently, there is no clinical treatment that specifically targets GIE after SCI, and emergence of a therapeutic target for secondary damage in SCI patients is of utmost need. Uric acid (UA), a product of purine synthesis, acts as an antioxidant by scavenging free radicals and preserves neuronal viability in several in vitro and in vivo SCI models. However, high systemic UA concentrations can be detrimental and lead to hypertension, kidney disease, and gout. Thus, there is need to develop a drug delivery system that can deliver UA locally to the target injured region. Natural polymers show high biocompatibility but lack the ability to be fabricated in such a way that the rate of drug release is controlled. In contrast, use of the synthetic polymer, poly (ɛ-caprolactone; PCL), offers an advantage over natural polymers since it is not only biodegradable and biocompatible, but it also has a controllable degradation rate and is compatible with a vast number of drugs. As such, it has been studied and used extensively in the context of drug delivery applications. Here, using the electrospinning technique, we developed a PCL-UA nanofiber mat containing UA, which has the potential as an implantable drug delivery carrier for UA. We then optimized delivery of UA via this PCL nanofiber mat in short bursts of 2 hours by coating the mats with PEGDA. We then optimized the effective dose of UA released from PCL nanofibers to protect neurons from GIE in organotypic spinal cord slice culture. We show that the mats decrease reactive oxygen species generation and cell death. The long-term goal of this project is to extend these studies in vivo, and ultimately, optimize use for SCI patients. This approach is therapeutically viable since PCL is an FDA approved polymer currently used to deliver multiple drugs and fully excreted from the body upon degradation without any toxic effects.

description: Motivated by interest in pedestrian traffic we study two lanes (one-dimensional lattices) of length $L$ that intersect at a single site. Each lane is modeled by a TASEP (Totally Asymmetric Exclusion Process). The particles enter and leave lane $σ$ (where $σ=1,2$) with probabilities $α_σ$ and $β_σ$, respectively. We employ the `frozen shuffle' update introduced in earlier work [C. Appert-Rolland et al, J. Stat. Mech. (2011) P07009], in which the particle positions are updated in a fixed random order. We find analytically that each lane may be in a `free flow' or in a `jammed' state. Hence the phase diagram in the domain $0\leqα_1,α_2\leq 1$ consists of four regions with boundaries depending on $β_1$ and $β_2$. The regions meet in a single point on the diagonal of the domain. Our analytical predictions for the phase boundaries as well as for the currents and densities in each phase are confirmed by Monte Carlo simulations.

Uneven Spatial Development in Neoliberal Chicago

Subjects: subject: urban planning
subject: neoliberal spatial development

description: Overall place-based public expenditure in Chicago has followed patterns of neoliberal spatial selectivity, where business and economic development is prioritized, primarily in and around the central business district or high income residential areas. This prioritization occurs at the expense of social benefits or democratically redistributive policies to help those in need. Tax Increment Financing (TIF) in particular has displayed the same patterns and has been known for egregious abuses. At the behest of critics, the City evaluated its use of TIF with a 2011 reform panel. However, afterwards no noticeable change was realized and TIF use continues within the neoliberal urban entrepreneurialist framework, instead of as a tool to help underserved areas.

description: We explore the anisotropic nature of Feshbach resonances in the collision between ultracold magnetic submerged-shell dysprosium atoms, which can only occur due to couplings to rotating bound states. This is in contrast to well-studied alkali-metal atom collisions, where most Feshbach resonances are hyperfine induced and due to rotation-less bound states. Our novel first-principle coupled-channel calculation of the collisions between open-4f-shell spin-polarized bosonic dysprosium reveals a striking correlation between the anisotropy due to magnetic dipole-dipole and electrostatic interactions and the Feshbach spectrum as a function of an external magnetic field. Over a 20 mT magnetic field range we predict about a dozen Feshbach resonances and show that the resonance locations are exquisitely sensitive to the dysprosium isotope.

description: The formation of new phases close to itinerant electron quantum critical points has been observed experimentally in many compounds. We present a unified analytical model that explains the emergence of new types of order around itinerant ferromagnetic quantum critical points. The central idea of our analysis is that certain Fermi-surface deformations associated with the onset of the competing order enhance the phase-space available for low-energy quantum fluctuations and so self-consistently lower the free energy. We demonstrate that this quantum order-by-disorder mechanism leads to instabilities towards the formation of spiral and d-wave spin nematic phases close to itinerant ferromagnetic quantum critical points in three spatial dimensions.

Tracking Magnetic Variability From High-Resolution Unpolarised Spectra
Creators: name: Mortier, Annelies
Publisher: name: Zenodo
Year: 2016

description: Discovering Earth-like exoplanets using the radial velocity (RV) technique is mainly being challenged by stellar activity. Only by understanding the variable signals imposed by the star itself will we be able to find the underlying planetary signals. Activity indicators, such as the FWHM of the spectral lines and the Ca II H&K emission, are already being used to understand the stellar variations. However, the high-resolution spectra that we have from the RV searches contain much more information. In this talk I will explain about a new technique of extracting information on the stellar magnetic field directly from the intensity spectrum. By combining thousands of lines, we can extract the Zeeman broadening effect. We apply this to the high-resolution spectra time series taken with HARPS and HARPS-N in order to disentangle the stellar magnetic signal from the signals from Earth-like planets.

description: Integrated quantum photonics is an appealing platform for quantum information processing, quantum communication and quantum metrology. In all these applications it is necessary not only to be able to create and detect Fock states of light but also to program the photonic circuits that implements some desired logical operation. Here we demonstrate a reconfigurable controlled two-qubit operation on a chip using a multiwaveguide interferometer with a tunable phase shifter. We find excellent agreement between theory and experiment, with a 0.98 \pm 0.02 average similarity between measured and ideal operations.
Entanglement Entropy of Gapped Phases and Topological Order in Three dimensions

description: We discuss entanglement entropy of gapped ground states in different dimensions, obtained on partitioning space into two regions. For trivial phases without topological order, we argue that the entanglement entropy may be obtained by integrating an `entropy density' over the partition boundary that admits a gradient expansion in the curvature of the boundary. This constrains the expansion of entanglement entropy as a function of system size, and points to an even-odd dependence on dimensionality. For example, in contrast to the familiar result in two dimensions, a size independent constant contribution to the entanglement entropy can appear for trivial phases in any odd spatial dimension. We then discuss phases with topological entanglement entropy (TEE) that cannot be obtained by adding local contributions. We find that in three dimensions there is just one type of TEE, as in two dimensions, that depends linearly on the number of connected components of the boundary (the `zeroth Betti number'). In D > 3 dimensions, new types of TEE appear which depend on the higher Betti numbers of the boundary manifold. We construct generalized toric code models that exhibit these TEEs and discuss ways to extract TEE in D >=3.

For more than 100 years astronomers have tried observing from balloons to avoid turbulence and extinction.nbsp;nbsp;New developments in card-size computers, RF equipment and satellite navigation have democratised the access to the stratosphere./p>

p>As a result of a ProAm collaboration with the Daedalus Team we have developed a low-cost multi-purpose platform with stratospheric balloons carrying up to 3 kg of scientific payload. The Daedalus Team is an amateur group that has been launching sounding probes since 2010. Since then the first two authors have provided scientific payloads for nighttime flights with the purpose of technology demonstration for astronomical observation./p>

p>It is a passive craft, with basic stabilisation and 2-hour length nominal mission. Current design has up to 4 observational ports, three at the sides of the square-shaped probe and one aiming at nadir for Earth Observation. The probe uses one or two meteorological sounding balloons to get out of the troposphere. The probe usually rises to 30km of altitude and then falls free with a parachute. The probe has GSM, RF and GPS beacons and some missions had also bidirectional communication. During the flight the probe is chased from ground using the beacons in order for recovery as all the data is stored inside./p>

p>The first of these flights was in 2010 as an instrumental test to monitor light. The same year a second flight over the city of Jaeacute;n successfully took the first images for scientific use. In 2014 the project was repeated over the city of Madrid, acquiring images of quality comparable to the ones from airborne instruments with a hundredth of the cost./p>

p>The other scientific objective of these night flights is the estimation of meteoroid influx at Earth through the observation of meteor showers. Observing meteors from the stratosphere improves detection efficiency thanks to much lower extinction and less background brightness. Other teams had already demonstrated the benefits of airborne observations for these objects. In 2011 the team sent a low-light video camera to observe the Draconids 2011 outburst. Unfortunately the recording system failed and then mission had to be redesigned. For Geminids 2012, Camelopardalids 2014 and Geminids 2015 the instruments have worked flawlessly and the data are under analysis. Imaging and video devices with broad-band filters have been employed and results are comparable with airborne and satellite products, especially for high-resolution images./p>

description: We study a new variant of the string matching problem called cross-document string matching, which is the problem of indexing a collection of documents to support an efficient search for a pattern in a selected document, where the pattern itself is a substring of another document. Several variants of this problem are considered, and efficient linear-space solutions are proposed with query time bounds that either do not depend at all on the pattern size or depend on it in a very limited way (doubly logarithmic). As a side result, we propose an improved solution to the weighted level ancestor problem.

description: Sub-subgiant stars (SSGs) lie red of the main-sequence and fainter than the red giant branch in optical color-magnitude diagrams, a region not easily populated by standard stellar evolution pathways. Discoveries of dozens of SSGs in both open and globular clusters solidifies these stars as a unique class sharing several properties: X-ray emission, photometric variability, and, where binary status is known, orbital periods between 2-18 days. While there has been speculation on what mechanisms may create these unusual stars, no theory has yet been developed to explain their origins. Here we focus on three hypotheses of SSG formation: (1) mass transfer in a binary system, (2) tidally induced mass loss from a subgiant star during a dynamical encounter, and (3) reduced luminosity due to magnetic fields that lower convective efficiency and produce large star spots. Using the stellar evolution code MESA, we develop evolutionary tracks for each of these hypotheses, and compare the expected stellar and orbital properties of these models with the six known SSGs in the two open clusters M67 and NGC 6791. We calculate the frequency with which each of these mechanisms may create SSG systems, and find that the magnetic field hypothesis is expected to create SSGs with the highest frequency in open clusters. Mass transfer and dynamical encounters may also create SSGs, but have lower expected formation frequencies. They may be more important mechanisms in globular clusters with higher encounter rates and larger populations of subgiants.

description: Given a principal bundle G \rightarrow P \rightarrow B (each being compact, connected and oriented) and a G-invariant metric h^{P} on P which induces a volume form μ^{P}, we consider the group of all unimodular automorphisms SAut(P,μ^{P}):={φ\in Diff(P) | φ^{*}μ^{P}=μ^{P} and φis G-equivariant} of P and determines its Euler equation a la Arnold. The resulting equations turn out to be (a particular case of) the Euler-Yang-Mills equations of an incompressible classical charged ideal fluid moving on B. It is also shown that the group SAut(P,μ^{P} is an extension of a certain volume preserving diffeomorphisms group of B by the gauge group Gau(P) of P.

description: The basic features of the dynamics of open quantum systems, such as the dissipation of energy, the decay of coherences, the relaxation to an equilibrium or non-equilibrium stationary state, and the transport of excitations in complex structures are of central importance in many applications of quantum mechanics. The theoretical description, analysis and control of non-Markovian quantum processes play an important role in this context. While in a Markovian process an open system irretrievably loses information to its surroundings, non-Markovian processes feature a flow of information from the environment back to the open system, which implies the presence of memory effects and represents the key property of non-Markovian quantum behavior. Here, we review recent ideas developing a general mathematical definition for non-Markoviantiy in the quantum regime and a measure for the degree of memory effects in the dynamics of open systems which are based on the exchange of information between system and environment. We further study the dynamical effects induced by the presence of system-environment correlations in the total initial state and design suitable methods to detect such correlations through local measurements on the open system.

Chandra And Kepler Monitoring Of Ultracool Dwarfs

description: We present the results of Chandra observation of L1 dwarf WISEP J190648.47+401106.8 (W1906+40 hereafter) and Kepler monitoring of L8 dwarf WISEP J060738.65+242953.4 (W0607+24 hereafter). W1906+40 was observed by Chandra for 49 ks on August 14, 2015. The net count of X-ray photons from this L dwarf is estimated to be ≈2 with the lower and upper limits equal to 0.44 and 6.07 respectively at 90 % confidence level. The time averaged X-ray luminosity over the duration of observation is found to be 1.87 × 10^25 erg s^−1 with the lower and upper limits equal to 4.03 × 10^24 erg s^−1 and 5.19 × 10^25 erg s^−1 respectively at 90 % confidence level. The corresponding X-ray activity level is log L_X ≈ -4.64. This dwarf does not follow the rotation ac- tivity relation as seen in earlier-type stars despite being a rapid rotator with period of 8.9 hours. In addition, total time averaged energy (UBVRI ) of white light flares observed in the same dwarf is calculated to be 5.25 × 10^25 which is 30% of the total time averaged flare energy (XUBVRI). W0607+24 was monitored by Kepler for 36 days during K2 Campaign 0. Kepler photometry rules out any possibility of stable periodic signals in the optical with amplitudes greater than 1.5% and periods between 1.5 hours and 2 days. The results are consistent with those obtained by Spitzer observations which show no variabiltiy at the 0.2% level over 10 hours each in the 3.6 and 4.5 micron bands.

Comparing student achievement and satisfaction in technology infused (hybrid) and traditional chemistry classrooms
Creators: name: Mulji, Waheeda
Publisher: name: University of British Columbia

description: Despite the growing use of the hybrid course delivery format in science education, there is a scarcity of research to support its effectiveness in enhancing student learning at the secondary school level. My research explores how a hybrid mode of course instruction compares with the traditional offline face-to-face mode of instruction in terms of student achievement and satisfaction. In order to assess the differences between the two course delivery formats, student satisfaction and achievement levels were measured in two Chemistry 12 classes. Findings demonstrated that students in the traditional offline face-to-face class were more satisfied than students in the hybrid class with respect to perceptions of course content and communication levels with the instructor and peers. With respect to students’ satisfaction with given grades and access to course materials, both the traditional offline class and the hybrid class yielded similar findings concerning course satisfaction. Results overall also showed that students in the hybrid class did not perform any better or worse than students in the traditional offline face-to-face class. Rather, student achievement and satisfaction levels in the hybrid format seem to depend on multiple factors not reducible to choice of format.

description: The coolest T and Y-class Brown Dwarf objects are very faint and are therefore very poorly understood, since they are barely detectable with the current astronomical instrumentation. The upcoming James Webb Space Telescope now in development for a launch in the Fall of 2018 will have vastly increased sensitivity in the near and mid-infrared compared to any current facilities and will not be affected by telluric absorption over its entire wavelength range of operations. As a result it will be an ideal tool to obtain information about the composition and temperature-pressure structure in these objects’ atmospheres. This presentation outlines the JWST guaranteed time observing plans for these studies. These plans comprise both spectro-photometric and spectroscopic observations of a selection of late T and Y-dwarf targets.

description: В XXI веке наблюдается чрезмерно активное развитие социальных сетей и, как следствие, виртуальных коммуникаций. В свою очередь, изменяется напряжение в социальном пространстве. В данном исследовании выявляется наличие корреляции между напряжением социального пространства и развитием виртуальных коммуникаций на примере города Санкт-Петербург. Корреляция выявлена: чем выше развитие виртуальных коммуникаций, тем меньше уровень социальной напряженности.
description: In the 21st century, there is an overly active development of social networks and, as a result, virtual communications. In turn, the tension in the social space is changing. This study reveals the existence of a correlation between the tension of social space and the development of virtual communications on the example of the city of St. Petersburg. The correlation is revealed: the higher the development of virtual communications, the lower the level of social tension.

description: We pursue the investigation of a previously proposed correlation between chemical properties and physical evolutionary stage of isolated low-mass star-forming regions. In the past, the NH3/CCS abundance ratio was suggested to be a potentially useful indicator for the evolutionary stage of cloud cores. We aim to study its applicability for isolated Bok globules. A sample of 42 Bok globules with and without signs of current star formation was searched for CCS(2-1) emission, the observations were complemented with NH3 measurements available in the literature and own observations. The abundance ratio of both molecules is discussed with respect to the evolutionary stage of the objects and in the context of chemical models. The NH3/CCS ratio could be assessed for 18 Bok globules and is found to be moderately high and roughly similar across all evolutionary stages from starless and prestellar cores towards internally heated cores harbouring protostars of Class 0, Class I or later. Bok globules with extremely high CCS abundance analogous to carbon-chain producing regions in dark cloud cores are not found. The observed range of NH3/CCS hints towards a relatively evolved chemical state of all observed Bok globules.

description: The Remote Associates Test (RAT) is a context-dependent retrieval task, which consists of a series of problems, each with three seemingly unrelated prompt words. The participant is asked to generate a single-word answer that is related to all prompt words. While the RAT has been used many times to study creativity and intelligence, this work uses the RAT to study semantic memory retrieval. This work presents multiple computational models of humans solving the RAT and investigates how prior knowledge, retrieval mechanisms, and word preference strategies influence the model’s ability to match human behavior. This research goes beyond previous work by investigating and comparing two types and five individual knowledge bases, including one never before used to study the RAT. This work also provides a new comprehensive modeling approach for the RAT that uses a cognitive architecture that incorporates well-known memory and processing components. In addition, this work contributes to the literature by extensively investigating semantic memory mechanisms on the RAT, such as base-level activation, spreading activation, and noise. This work also presents original findings and conclusions from an analysis on the intermediate processing people report when solving RAT problems. The conclusions of the work include the finding that a cognitive model, created in Soar, with long-term memory spreading activation through word-association strengths matches aggregate human problem difficulty, with the best model achieving a coefficient of determination of 0.98 and mean-squared error of 0.29. A similar model that uses a prompt-word focus strategy matches an individual participant’s intermediate processing on average with an 84.8 percent relative attempt overlap score. Based on my new data analysis and modeling work, I conclude that when looking at the intermediate processing of individual participants, there is evidence that people attend to a particular prompt word based on relative position, word frequency, or fan.
An X-Ray Study of Supernova Remnant N49 and Soft Gamma-Ray Repeater 0526-66 in the Large Magellanic Cloud

description: We report on the results from our deep Chandra observation (120 ks) of the supernova remnant (SNR) N49 and soft Gamma-ray repeater (SGR) 0526-66 in the Large Magellanic Cloud. We firmly establish the detection of an ejecta "bullet" beyond the southwestern boundary of N49. The X-ray spectrum of the bullet is distinguished from that of the main SNR shell, showing significantly enhanced Si and S abundances. We also detect an ejecta feature in the eastern shell, which shows metal overabundances similar to those of the bullet. If N49 was produced by a core-collapse explosion of a massive star, the detected Si-rich ejecta may represent explosive O-burning or incomplete Si-burning products from deep interior of the supernova. On the other hand, the observed Si/S abundance ratio in the ejecta may favor Type Ia origin for N49. We refine the Sedov age of N49, tau_Sed ~ 4800 yr, with the explosion energy E_0 ~ 1.8 x 10^51 erg. Our blackbody (BB) + power law (PL) model for the quiescent X-ray emission from SGR 0526-66 indicates that the PL photon index (Gamma ~ 2.5) is identical to that of PSR 1E1048.1-5937, the well-known candidate transition object between anomalous X-ray pulsars and SGRs. Alternatively, the two-component BB model implies X-ray emission from a small (R ~ 1 km) hot spot(s) (kT ~ 1 keV) in addition to emission from the neutron star's cooler surface (R ~ 10 km, kT ~ 0.4 keV). There is a considerable discrepancy in the estimated column toward 0526-66 between BB+PL and BB+BB model fits. Discriminating these spectral models would be crucial to test the long-debated physical association between N49 and 0526-66.
