Unwrapping the neolithic package: Wadi Shu'eib and Kholetria-Ortos in perspective
Creators: name: Cooper, Jason Brandon
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Archaeological research of the Neolithic period in Southwest Asia depicts socio-cultural developments and proto-urban villages, resulting from an intensifying agro-economy, emerging simultaneously during the first 5,000 years of the Holocene (11,000 to 6,000 bp). Kholetria-Ortos, Cyprus, and Wadi Shu'eib, Jordan, are highlighted in this thesis to illustrate variability found in a proposed "Neolithic package." The "Neolithic package" is a time capsule of items and ideas centered on sedentary villages participating in a domesticated plant/animal driven economy that provided subsistence and surplus to a growing population. Analysis of the recovered artifacts from both sites finds evidence of cultural variability across time and space. Environmental and cultural interactions are speculated upon as possible causation for differences seen between these two sites. A world view for the Neolithic experience is hypothesized by incorporating components of a core/periphery model.

description: Properties of pairs of product conjugate connections are stated with a special view towards the integrability of the given almost product structure. We define the analogous in product geometry of the structural and the virtual tensors from the Hermitian geometry and express the product conjugate connections in terms of these tensors. Some examples from the geometry of a pair of complementary distributions are discussed and for this case the above structural and virtual tensors are expressed in terms of O'Neill-Gray tensor fields.

description: Heat flow in nanomaterials is an important area of study, with both fundamental and technological implications. However, little is known about heat flow in two-dimensional (2D) devices or interconnects with dimensions comparable to the phonon mean free path (mfp). Here, we find that short, quarter-micron graphene samples reach ~35% of the ballistic heat conductance limit up to room temperature, enabled by the relatively large phonon mfp (~100 nm) in substrate-supported graphene. In contrast, patterning similar samples into nanoribbons (GNRs) leads to a diffusive heat flow regime that is controlled by ribbon width and edge disorder. In the edge-controlled regime, the GNR thermal conductivity scales with width approximately as ~W^{1.8+/-0.3}, being about 100 W/m/K in 65-nm-wide GNRs, at room temperature. Manipulation of device dimensions on the scale of the phonon mfp can be used to achieve full control of their heat-carrying properties, approaching fundamentally limited upper or lower bounds.

description: In this article, we propose a new estimator of panel data models with random interactive effects and multiple structural breaks that is suitable when the number of time periods, T, is fixed and only the number of cross-sectional units, N, is large. This is done by viewing the determination of the breaks as a shrinkage problem, and to estimate both the regression coefficients, and the number of breaks and their locations by applying a version of the Lasso approach. We show that with probability approaching one the approach can correctly determine the number of breaks and the dates of these breaks, and that the estimator of the regime-specific regression coefficients is consistent and asymptotically normal. We also provide Monte Carlo results suggesting that the approach performs very well in small samples, and empirical results suggesting that while the coefficients of the controls are breaking, the coefficients of the main deterrence regressors in a model of crime are not.

description: In 2012 the Specialists Task Force (STF) 442 appointed by the European Telcommunication Standards Institute (ETSI) explored the possibilities of using Model Based Testing (MBT) for test development in standardization. STF 442 performed two case studies and developed an MBT-methodology for ETSI. The case studies were based on the ETSI-standards GeoNetworking protocol (ETSI TS 102 636) and the Diameter-based Rx protocol (ETSI TS 129 214). Models have been developed for parts of both standards and four different MBT-tools have been employed for generating test cases from the models. The case studies were successful in the sense that all the tools were able to produce the test suites having the same test adequacy as the corresponding manually developed conformance test suites. The MBT-methodology developed by STF 442 is based on the experiences with the case studies. It focusses on integrating MBT into the sophisticated standardization process at ETSI. This paper summarizes the results of the STF 442 work.

description: This paper provides methods for flexibly capturing unobservable heterogeneity from longitudinal data in the context of an exponential family of distributions. The group memberships of individual units are left unspecified, and their heterogeneity is influenced by group-specific unobservable factor structures. The model includes, as special cases, probit, logit, and Poisson regressions with interactive fixed effects along with unknown group membership. We discuss a computationally efficient estimation method and derive the corresponding asymptotic theory. Uniform consistency of the estimated group membership is established. To test heterogeneous regression coefficients within groups, we propose a Swamy-type test that allows for unobserved heterogeneity. We apply the proposed method to the study of market structure of the taxi industry in New York City. Our method unveils interesting and important insights from large-scale longitudinal data that consist of over 450 million data points.

description: We study analytically and numerically an optical analogue of Dirac solitons in binary waveguide arrays in presence of Kerr nonlinearity. Pseudo-relativistic soliton solutions of the coupled-mode equations describing dynamics in the array are analytically derived. We demonstrate that with the found soliton solutions, the coupled mode equations can be converted into the nonlinear relativistic 1D Dirac equation. This paves the way for using binary waveguide arrays as a classical simulator of quantum nonlinear effects arising from the Dirac equation, something that is thought to be impossible to achieve in conventional (i.e. linear) quantum field theory.
Aberration in proper motions for stars in our Galaxy

description: Accelerations of both the solar system barycenter (SSB) and stars in the Milky Way cause a systematic observational effect on the stellar proper motions, which was first studied in the early 1990s and developed by J. Kovalevsky (aberration in proper motions, 2003, A&A, 404, 743). This paper intends to extend that work and aims to estimate the magnitude and significance of the aberration in proper motions of stars, especially in the region near the Galactic center. We adopt two models for the Galactic rotation curve to evaluate the aberrational effect on the Galactic plane. Based on the theoretical developments, we show that the effect of aberration in proper motions depends on the galactocentric distance of stars; it is dominated by the acceleration of stars in the central region of the Galaxy. Within 200 pc from the Galactic center, the systematic proper motion can reach an amplitude larger than 1000 uas/yr by applying a flat rotation curve. With a more realistic rotation curve which is linearly rising in the core region of the Galaxy, the aberrational proper motions are limited up to about 150 uas/yr. Then we investigate the applicability of the theoretical expressions concerning the aberrational proper motions, especially for those stars with short period orbits. If the orbital period of stars is only a fraction of the light time from the star to the SSB, the expression proposed by Kovalevsky is not appropriate. With a more suitable formulation, we found that the aberration has no effect on the determination of the stellar orbits on the celestial sphere. The aberrational effect under consideration is small but not negligible with high-accurate astrometry in the future, particularly in constructing the Gaia celestial reference system realized by Galactic stars.

description: Photoassociation, assembling molecules from atoms using laser light, is limited by the low density of atom pairs at sufficiently short interatomic separations. Here, we show that non-resonant light with intensities of the order of 10^10 W/cm^2 modifies the thermal cloud of atoms, enhancing the Boltzmann weight of shape resonances and pushing scattering states below the dissociation limit. This leads to an enhancement of photoassociation rates by several orders of magnitude and opens the way to significantly larger numbers of ground state molecules in a thermal ensemble than achieved so far.
Sulle tracce delle guaritrici nel Cinquecento e primo Seicento attraverso la lente del teatro shakespeariano

description: In un ormai famoso scritto del 1928, Una stanza tutta per sé, l’autrice inglese Virginia Woolf immagina che una sorella di Shakespeare avesse intrapreso la carriera teatrale: carriera però rimasta senza successo. Secondo la Woolf, ciò fu dovuto al fatto che all’epoca le donne erano escluse dai teatri. Nel Cinque e Seicento la situazione era simile in tutte le professioni, con qualche eccezione nel campo della storiografia e della medicina. Questo saggio indagherà sulla vicenda delle cosiddette ‘wise women’ o ‘herb women’, ma anche di altre donne che in Inghilterra avrebbero potuto iscriversi a Oxford o Cambridge per studiare medicina se il Royal College non si fosse opposto. Per la nostra analisi ci riferiremo in particolare a due testi shakespeariani, Amleto e Tutto è bene quel che finisce bene, in cui due figure femminili, Ofelia e Elena, sono interessanti per il nostro discorso: Ofelia dimostra una conoscenza delle erbe a livello curativo e simbolico, mentre Elena ha imparato la professione dal padre, un rinomato medico.

description: Astronomical observations confirm that gravitational force decreases with the square of the distance. If the gravitational force in the centre of Sagittarius A* were close to infinity and would decrease with the square of the distance, our Milky Way could not exist as we observe it. This fact is irrefutable proof that there is no gravitational singularity in the centre of Sagittarius A* and in general, there is no gravitational singularity in the centre of a black hole.

description: Coronagraphy is a powerful technique to achieve high contrast imaging and hence to image faint companions around bright targets. Various concepts have been used in the visible and near-infrared regimes, while coronagraphic applications in the mid-infrared remain nowadays largely unexplored. Vector vortex phase masks based on concentric subwavelength gratings show great promise for such applications. We aim at producing and validating the first high-performance broadband focal plane phase mask coronagraphs for applications in the mid-infrared regime, and in particular the L band with a fractional bandwidth of ~16% (3.5-4.1 μm). Based on rigorous coupled wave analysis, we designed an annular groove phase mask (AGPM) producing a vortex effect in the L band, and etched it onto a series of diamond substrates. The grating parameters were measured by means of scanning electron microscopy. The resulting components were then tested on a mid-infrared coronagraphic test bench. A broadband raw null depth of 2 x 10^{-3} was obtained for our best L-band AGPM after only a few iterations between design and manufacturing. This corresponds to a raw contrast of about 6 x 10^{-5} (10.5 mag) at 2λ/D. This result is fully in line with our projections based on rigorous coupled wave analysis modeling, using the measured grating parameters. The sensitivity to tilt and focus has also been evaluated. After years of technological developments, mid-infrared vector vortex coronagraphs finally become a reality and live up to our expectations. Based on their measured performance, our L-band AGPMs are now ready to open a new parameter space in exoplanet imaging at major ground-based observatories.

Results of comparative experiments with a tool implementing this approach are presented.

Glazing type vs orientation: A comparison of solar gain reduction in Las Vegas product houses
Creators: name: Buchanan, Lisa Evelyn
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: This study makes a comparison between the effectiveness of reducing solar gain through glass areas by either changing the glazing type or reorienting the glazing on typical Las Vegas, Nevada product homes. A survey of model houses was conducted to establish a set of size ranges in which the models were characterized. Solar gain comparisons were done for the month of July on three representative models from each range. The solar gain was considered for clear, tinted and low-e coated glass with the models oriented in each of the four cardinal directions. This same comparison was then performed on a year long basis through the utilization of the RESFEN software program. Finally, the relative effectiveness of each product/method is discussed with regards to the square footage of the models.

description: We provide a methodology that efficiently combines the statistical models of nowcasting with the survey information for improving the (density) nowcasting of US real GDP. Specifically, we use the conventional dynamic factor model together with stochastic volatility components as the baseline statistical model. We augment the model with information from the survey expectations by aligning the first and second moments of the predictive distribution implied by this baseline model with those extracted from the survey information at various horizons. Results indicate that survey information bears valuable information over the baseline model for nowcasting GDP. While the mean survey predictions deliver valuable information during extreme events such as the Covid-19 pandemic, the variation in the survey participants’ predictions, often used as a measure of ‘ambiguity’, conveys crucial information beyond the mean of those predictions for capturing the tail behavior of the GDP distribution.

description: The interaction of secondary flows with the main passage flow in turbomachines results in entropy generation and in aerodynamic loss. This loss source is most relevant to low aspect ratio blades. One approach for reducing this flow energy loss is by end-wall contouring. However, limited work has been reported on using non-axisymmetric end-walls at the stator casing and on its interaction with the tip leakage flow. In this paper, a non-axisymmetric end-wall design method for the stator casing is implemented through a novel surface definition, towards mitigating secondary flow losses. This design is tested on a three-dimensional axial turbine RANS model built in OpenFOAM Extend 3.2, with 𝑘 − 𝜔 SST turbulence closure. Flow analysis confirm the foundations of the new surface definition approach, which is implemented using Alstom Process and Optimization Workbench (APOW) software. Computer-based optimization of the surface topology is demonstrated towards automating the design process of axial turbines in an industrial design workflow. The design is optimized using the total pressure loss across the first stator and across the full stage, as the target function. Numerical predictions of the 1.5 stage axial turbine show the positive impact of the optimized casing design on the efficiency that increases by 0.69% against the benchmark axisymmetric stage from RTWH Aachen, which is validated against experiment. The new non-axisymmetric casing is also beneficial at off-design condition. The effective mitigation of the secondary flows is predicted to give a 0.73% efficiency gain off-design.
Location of the target pitch within a vibrato wave
Creators: name: Clark, David Frank
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: The current study investigated the relationship between the vibrato wave and the target pitch while eliminating some of the methodological problems that have plagued such research in the past. Three commercially-recorded selections were chosen for each of seven artists (for a total of 21 selections), and modern computer equipment was used to extract pitch information for each of six to fourteen notes from each selection. The chosen selections were all accompanied so that the target pitch could be determined from the accompaniment, and target pitch location within the vibrato wave was quantified absolutely and relatively. In general, the target pitch lay at or slightly below (average 4.29 cents below) the vibrato wave mean, and an analysis of variance revealed no significant differences between artists. Analyses of variance within each artist showed no differences between selections except for the soprano, who had one selection where the target pitch was generally above the vibrato wave mean.

description: Time-varying parameter VARs with stochastic volatility are routinely used for structural analysis and forecasting in settings involving a few endogenous variables. Applying these models to high-dimensional datasets has proved to be challenging due to intensive computations and over-parameterization concerns. We develop an efficient Bayesian sparsification method for a class of models we call hybrid TVP-VARs—VARs with time-varying parameters in some equations but constant coefficients in others. Specifically, for each equation, the new method automatically decides whether the VAR coefficients and contemporaneous relations among variables are constant or time-varying. Using US datasets of various dimensions, we find evidence that the parameters in some, but not all, equations are time varying. The large hybrid TVP-VAR also forecasts better than many standard benchmarks.
The geology and structures in the northern Hiko Range, Lincoln county, Nevada
Creators: name: Switzer, Douglas Duane
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: In the northern Hiko Range, extension occurred in four temporally distinct episodes during the Cenozoic. The extensional events are (1) prevolcanic ({dollar}>{dollar}27.31 {dollar}\pm{dollar} 0.03 Ma), (2) synvolcanic (between 22.78 {dollar}\pm{dollar} 0.03 and 18.5 {dollar}\pm{dollar} 0.4 Ma), (3) Tertiary (?) postvolcanic ({dollar}<{dollar}14.7 {dollar}\pm{dollar} 0.4 Ma), and (4) Pliocene (?)-Quaternary. Four fault sets are delineated based on orientation and cross-cutting relationships: (1) northeast- to northwest-striking moderately dipping prevolcanic faults, (2) east-west-striking, steeply dipping synvolcanic faults, (3) east-west- and east-northeast-striking, steeply dipping Tertiary (?) postvolcanic faults, and (4) generally north-striking steeply dipping Pliocene (?)-Quaternary faults; Prevolcanic faults in the northern Hiko Range are interpreted to be footwall faults to an Oligocene age extensional system. These faults increase the area known to be affected by Oligocene extension and support existing evidence that suggests this event is widespread; A tectonomagmatic rift model has been proposed to explain synvolcanic extension during the Tertiary in the northern Basin and Range province. However, the majority of the faults are postvolcanic and are not readily explained by the tectonomagmatic rift model. Both east-west- and east-northeast-striking oblique-slip faults occur along the Timpahute lineament. They appear to be the result of stresses produced by the Tertiary southward sweep of volcanism, in combination with a reduction of plate boundary stresses, which occurred after volcanism; The Hiko fault zone is a segmented fault of Pliocene (?)-Quaternary age that may still be active and is interpreted to be the bounding fault of a half graben in Pahranagat Valley.

Five Misunderstandings About Case-Study Research
Creators: name: Flyvbjerg, Bent
Publisher: name: arXiv
Year: 2013
Subjects: subject: General Finance (q-fin.GN)
subject: FOS: Economics and business

description: This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypotheses, while other methods are more suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more good case studies.

description: The density of electronic one-particle states in monolayer graphene is studied by performing the Hybrid Monte-Carlo simulations of the tight-binding model for electrons on the pi orbitals of carbon atoms which make up the graphene lattice. Density of states is approximated as a derivative of the number of particles over the chemical potential at sufficiently small temperature. Simulations are performed in the partially quenched approximation, in which virtual particles and holes have zero chemical potential. It is found that the Van Hove singularity becomes much sharper than in the free tight-binding model. Simulation results also suggest that the Fermi velocity increases with interaction strength up to the transition to the phase with spontaneously broken chiral symmetry.

description: Short-length Reed--Muller codes under majority-logic decoding are of particular importance for efficient hardware implementations in real-time and embedded systems. This paper significantly improves Chen's two-step majority-logic decoding method for binary Reed--Muller codes $\text{RM}(r,m)$, $r \leq m/2$, if --- systematic encoding assumed --- only errors at information positions are to be corrected. Some general results on the minimal number of majority gates are presented that are particularly good for short codes. Specifically, with its importance in applications as a 3-error-correcting, self-dual code, the smallest non-trivial example, $\text{RM}(2,5)$ of dimension 16 and length 32, is investigated in detail. Further, the decoding complexity of our procedure is compared with that of Chen's decoding algorithm for various Reed--Muller codes up to length $2^{10}$.

title: Promoting Critical Thinking In General Biology Courses: The Case Of The White Widow Spider
Creators: name: Wilson, Joseph S
Publisher: name: Utah State University
Year: 2019

description: It is generally accepted that critical thinking is an important and, likely, essential, component of success in college and beyond. Despite the unanimity, only a low percentage of students in the U.S. can demonstrate critical thinking proficiency on standardized exams. This phenomenon may result from instructors using a reductionist view of critical thinking and focusing on learning processes rather than on evaluation of intellectual resources. In general biology courses, I use a non-threatening, active-learning, group activities to promote critical thinking. For example, students are presented with an email from a member of the community and asked to formulate a response using the internet as their resource. I have found that using this non-threatening activity near the start of the semester promotes students’ acquisition of critical thinking skills and allows me to present assignments focusing on more controversial topics that require critical thinking later in the semester.

description: A new symplectic N-body integrator is introduced, one designed to calculate the global 360 degree evolution of a self-gravitating planetary ring that is in orbit about an oblate planet. This freely-available code is called epi_int, and it is distinct from other such codes in its use of streamlines to calculate the effects of ring self-gravity. The great advantage of this approach is that the perturbing forces arise from smooth wires of ring matter rather than discreet particles, so there is very little gravitational scattering and so only a modest number of particles are needed to simulate, say, the scalloped edge of a resonantly confined ring or the propagation of spiral density waves. The code is applied to the outer edge of Saturn's B ring, and a comparison of Cassini measurements of the ring's forced response to simulations of Mimas' resonant perturbations reveals that the B ring's surface density at its outer edge is 195+-60 gm/cm^2 which, if the same everywhere across the ring would mean that the B ring's mass is about 90% of Mimas' mass. Cassini observations show that the B ring-edge has several free normal modes, which are long-lived disturbances of the ring-edge that are not driven by any known satellite resonances. Although the mechanism that excites or sustains these normal modes is unknown, we can plant such a disturbance at a simulated ring's edge, and find that these modes persist without any damping for more than ~10^5 orbits or ~100 yrs despite the simulated ring's viscosity of 100 cm^2/sec. These simulations also indicate that impulsive disturbances at a ring can excite long-lived normal modes, which suggests that an impact in the recent past by perhaps a cloud of cometary debris might have excited these disturbances which are quite common to many of Saturn's sharp-edged rings.

Channel Coding and Lossy Source Coding Using a Constrained Random Number Generator

description: Stochastic encoders for channel coding and lossy source coding are introduced with a rate close to the fundamental limits, where the only restriction is that the channel input alphabet and the reproduction alphabet of the lossy source code are finite. Random numbers, which satisfy a condition specified by a function and its value, are used to construct stochastic encoders. The proof of the theorems is based on the hash property of an ensemble of functions, where the results are extended to general channels/sources and alternative formulas are introduced for channel capacity and the rate-distortion region. Since an ensemble of sparse matrices has a hash property, we can construct a code by using sparse matrices, where the sum-product algorithm can be used for encoding and decoding by assuming that channels/sources are memoryless.

A forest-fire analogy to explain the b-value of the Gutenberg-Richter law for earthquakes

description: The Drossel-Schwabl model of forest fires can be interpreted in a coarse grained sense as a model for the stress distribution in a single planar fault. Fires in the model are then translated to earthquakes. I show that when a second class of trees that propagate fire only after some finite time is introduced in the model, secondary fires (analogous to aftershocks) are generated, and the statistics of events becomes quantitatively compatible with the Gutenberg Richter law for earthquakes, with a realistic value of the $b$ exponent. The change in exponent is analytically demonstrated in a simplified percolation scenario. Experimental consequences of the proposed mechanism are indicated.

description: We study the problem of deriving a specification for a third-party component, based on the specification of the system and the environment in which the component is supposed to reside. Particularly, we are interested in using component specifications for conformance testing of black-box components, using the theory of input-output conformance (ioco) testing. We propose and prove sufficient criteria for decompositionality, i.e., that components conforming to the derived specification will always compose to produce a correct system with respect to the system specification. We also study the criteria for strong decomposability, by which we can ensure that only those components conforming to the derived specification can lead to a correct system.

Aspergillus tritici

description: Aspergillus section Candidi encompasses white- or yellow-sporulating species mostly isolated from indoor and cave environments, food, feed, clinical material, soil and dung. Their identification is non-trivial due to largely uniform morphology. This study aims to re-evaluate the species boundaries in the section Candidi and present an overview of all existing species along with information on their ecology. For the analyses, we assembled a set of 113 strains with diverse origin. For the molecular analyses, we used DNA sequences of three house-keeping genes (benA, CaM and RPB2) and employed species delimitation methods based on a multispecies coalescent model. Classical phylogenetic methods and genealogical concordance species recognition approaches were used for comparison. Phenotypic studies involved comparisons of macromorphology on four cultivation media, seven micromorphological characters and growth at temperatures ranging from 10 to 45 °C. Based on our results, all currently accepted species gained further support, while two new species are proposed (A. magnus and A. tenebricus). In addition, we proposed the new name A. neotritici to replace an invalidly described A. tritici. The revised section Candidi now comprises nine species, some of which manifest a high level of intraspecific genetic and/or phenotypic variability (e.g. A. subalbidus and A. campestris) while others are more uniform (e.g. A. candidus or A. pragensis). The growth rates on different media and at different temperatures, colony colours, production of soluble pigments, stipe dimensions and vesicle diameters contributed the most to species differentiation.

Feeling Pain/Making Kin in the Brooklyn Noise Music Scene
Creators: name: Farrow, David
Publisher: name: Current Musicology
Year: 2020

description: Drawing from ethnographic research at Brooklyn Do-It-Yourself venues conducted between February 2018-December 2019, this paper examines the formation of queer kinship through social belonging fostered during noise music performances. Social belonging within DIY spaces produces shared awareness and understandings that sustain life for marginalized people through circulations of material resources, care, and guidance. Through an ethnographic and theoretical examination of moshing during a performance by queer dance-punk group Deli Girls, social belonging is shown to emerge through the collective experience of performance. In turn, this sense of social belonging is the affective accompaniment to queer kinship within the Brooklyn underground noise scene. This paper then considers the relationship between DIY venues and gentrification by locating the absence of an affective analysis of performance within critics’ accounts of artist-led gentrification. To conclude, the capacity for an expansive queer kinship between artists and neighborhood residents is considered as a strategy for confronting the appropriation of DIY spaces and cultures by real estate developers for profit.

description: Detailed knowledge of mechanical parameters such as cell elasticity, stiffness of the growth substrate, or traction stresses generated during axonal extensions is essential for understanding the mechanisms that control neuronal growth. Here we combine Atomic Force Microscopy based force spectroscopy with Fluorescence Microscopy to produce systematic, high-resolution elasticity maps for three different types of live neuronal cells: cortical (embryonic rat), embryonic chick dorsal root ganglion, and P-19 (mouse embryonic carcinoma stem cells) neurons. We measure how the stiffness of neurons changes both during neurite outgrowth and upon disruption of microtubules of the cell. We find reversible local stiffening of the cell during growth, and show that the increase in local elastic modulus is primarily due to the formation of microtubules. We also report that cortical and P-19 neurons have similar elasticity maps, with elastic moduli in the range 0.1-2 kPa, with typical average values of 0.4 kPa (P-19) and 0.2 kPa (cortical). In contrast, DRG neurons are stiffer than P-19 and cortical cells, yielding elastic moduli in the range 0.1-8 kPa, with typical average values of 0.9 kPa. Finally, we report no measurable influence of substrate protein coating on cell body elasticity for the three types of neurons.

PS1-10jh - a tidal disruption event with an extremely low disk temperature

Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: The cooler than expected optical-UV transient PS1-10jh detected by the Pan-STARRS1 survey is probably related to a tidal disruption event in which a He-rich stellar core remnant is implied. The evolution of bound debris during the disk phase is studied by solving the hydrodynamic equations. The model provides a good fit either of the raising part of the light curve in the bands g_(P1), r_(P1), and i_(P1) or in the early decay. The parameters characterizing this optimized model are the mass of the central black hole, i.e., 6.3x10^6 Msun and the critical Reynolds number Re = 10^4 that fixes the viscosity and the accretion timescale. Such a high value of Re explains the low disk temperature and the consequent absence of X-ray emission. The predicted bolometric peak luminosity is about 10^45 erg/s and the predicted total radiated energy is about Erad=2.67x10^(51) erg.
