Fatigue of aluminum as affected by temperature and intermittent periods of rest
Creators: name: Berry, John Warren
Publisher: name: California Institute of Technology
Year: 1956
Subjects: Aeronautics

description: This investigation was undertaken in an attempt to determine the behavior of high purity aluminum when subjected to fatigue stressing in rotary bending at various elevated temperatures, and also to study the effects on fatigue life when the material was given intermittent periods of rest. Two types of rest periods were given; 1) room temperature resting from fatigue cycling at elevated temperature, and 2) resting at higher temperature after stressing at ambient temperature. Because of the limited time available and the desire to apply statistical methods of analysis, testing was restricted to only a single stress level for each phase of the experiment.

Up to the highest temperature tested (600[degrees]F), results for continuous stress cycling indicate a gradual reduction in fatigue life with temperature. Rest periods at room temperature contributed only negligible changes in fatigue life, but all tests with rest periods at elevated temperature disclosed a sizable increase. The increase in fatigue life was a maximum when resting was carried out at temperatures in the neighborhood of the recrystallization temperature. In addition, it is curious to note, that in the continuous cycling tests, scatter of results was a sharp minimum at recrystallization temperature.

description: Turbulence in a superfluid in the zero temperature limit consists of a dynamic tangle of quantized vortex filaments. Different types of turbulence are possible depending on the level of correlations in the orientation of vortex lines. We provide an overview of turbulence in superfluid $^4$He with a particular focus on recent experiments probing the decay of turbulence in the zero temperature regime below 0.5 K. We describe extensive measurements of the vortex line density during the free decay of different types of turbulence: ultraquantum and quasiclassical turbulence in both stationary and rotating containers. The observed decays and the effective dissipation as a function of temperature are compared with theoretical models and numerical simulations.

description: Type-I X-ray bursts are thermonuclear explosions occurring in the surface layers of accreting neutron stars. These events are powerful probes of the physics of neutron stars and their surrounding accretion flow. We analyze a very energetic type-I X-ray burst from the neutron star low-mass X-ray binary IGR J17062-6143 that was detected with Swift on 2012 June 25. The light curve of the ~18 min long X-ray burst tail shows an episode of ~10 min during which the intensity is strongly fluctuating by a factor of ~3 above and below the underlying decay trend, on a time scale of seconds. The X-ray spectrum reveals a highly significant emission line around ~1 keV, which can be interpreted as a Fe-L shell line caused by irradiation of cold gas. We also detect significant absorption lines and edges in the Fe-K band, which are strongly suggestive of the presence of hot, highly ionized gas along the line of sight. None of these features are present in the persistent X-ray spectrum of the source. The time scale of the strong intensity variations, the velocity width of the Fe-L emission line (assuming Keplerian motion), and photoionization modeling of the Fe-K absorption features each independently point to gas at a radius of ~1E3 km as the source of these features. The unusual X-ray light curve and spectral properties could have plausibly been caused by a disruption of the accretion disk due to the super-Eddington fluxes reached during the X-ray burst.

description: This paper continues a series in which we developed a non-parametric method to measure inhomogeneities in the gas distribution from X-ray observations of galaxy clusters. In this work, we apply our method to Chandra X-ray observations of Abell 133 and present the determination of the gas clumping factor from X-ray cluster data. We find that the gas clumping factor in Abell 133 increases with radius and reaches $\sim 2-3$ at $0.9\,R_{200}$. This is in good agreement with the predictions of hydrodynamical simulations and our previous determination. We then observe a general trend of steepening in the radial profiles of the clumping-corrected gas density beyond $0.3\, R_{200}$, with a logarithmic slope of $\sim 2.6$ at $0.9\,R_{200}$. The observed density profiles appear to be flatter compared to simulations, but in agreement with previous observational findings. In addition, we observe that the measured temperature decreases steadily with radius toward the outskirts of A133, while the entropy increases monotonically with radius, gently flattening in the outer volumes. With respect to theoretical predictions from pure gravitational collapse, the results presented here point to an entropy excess in the central regions, which extends out to large radii. These results suggest that gas inhomogeneities should be treated properly when interpreting X-ray measurements in the envelope of galaxy clusters. We finally discuss how the brightness distribution keeps a record of the large-scale structures formation scenario, providing a snapshot of the 'melting pot' in the virialization region.

description: In the first of this thesis the nature of random noise, which
arise and theoretically cannot be eliminated from radio receivers, is
described.

Nyquist equation, pertaining to the amount of noise generated in
a resistor, is rederived by a simple method. The original equation as
derived by Nyquist, is found to be valid, only, for physically
realizable impedances of the minimum reactance type.

The general problem of a passive electric network excited by random
sources is treated; a useful principle is developed for its solution.

Part II treats of the definition of the noise figure of a four
terminal network and the most important methods available for its
measurement. An improved noise generator for the measurement of noise
figure is described.

description: We present an analytical study of continuum 4d SU(2) gauge Higgs models with a single Higgs field with fixed length in either the fundamental or adjoint representation. We aim at analytically probing the renowned predictions of Fradkin & Shenker on the phase diagram in terms of confinement versus Higgs behaviour, obtained for the lattice version of the model. We work in the Landau version of the 't Hooft R_ξgauges in which case we can access potential nonperturbative physics related to the existence of the Gribov copies. In the fundamental case, we clearly show that in the perturbative regime of small gauge coupling constant g and large Higgs vacuum expectation value v, there is a Higgs phase with Yukawa gauge boson propagators without Gribov effects. For a small value of the Higgs vev v and/or large g, we enter a region with Gribov type propagators that have no physical particle interpretation: the gauge bosons are as such confined. The transition between both behaviours is found to be continuous. In the adjoint case, we find evidence of a more drastic transition between the different behaviours for the propagator of the off-diagonal gauge bosons, whereas the "photon", i.e. the diagonal component of the gauge field, displays a propagator of the Gribov type. In the limit of infinite Higgs condensate, we show that a massless photon is recovered. We compare our findings with those of Fradkin & Shenker as well as with more recent numerical lattice simulations of the fundamental Higgs model. We also carefully discuss in which region of the parameter space (v,g) our approximations are trustworthy.

PLASMA MEMBRANE SIALIDASE NEU3 SILENCING EFFECTS ON THE MOLECULAR PHENOTYPE OF MELANOMA CELLS
Creators: name: JEYASEELAN, BLISS RAMYA JOAN
Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: Human melanoma has been shown to be marked by an atypical cellular ganglioside profile and by the upregulation of plasma membrane sialidase NEU3. In this PhD thesis, I analyzed NEU3 silencing effects on the two human primary melanoma cell lines, named L3 and L6. These cell lines were stably transfected with a lentiviral vector. Previous results already demonstrated that NEU3 silenced melanoma cells reduced their migration potential and their growth in soft agar medium. Based on these data, my PhD work was focused towards the molecular features and signaling pathways alterations induced by NEU3 silencing in primary melanoma cell lines. Whole genome microarray analysis revealed the presence of differentially expressed genes above all associated with migration, motility, and control of cell death (G0 biological processes enrichment analysis). Some of these genes were validated by Real Time PCR: MAL, SEMA 3B, SEMA 3C and SEMA 5A. NEU3 silenced clones of both cell lines, 3C, 6A and 6B underwent to the upregulation of MAL, SEMA 3B and 3C. In contrast, SEMA 5A was downregulated. Different expression of markers related to epithelial mesenchymal transitions (N and E cadherin, MITF, vimentin, claudin 1, zo 1) was also revealed in NEU3 silenced clones. This proved the acquisition of a different molecular phenotype after NEU3 silencing that could explain the less motile properties. Moreover, we analyzed the activation of signaling pathways involved in these processes and we found a less activation of PI3K/AKT/PRAS40 axis and p38 kinases. Significantly, both these signaling pathways are involved in melanoma migration and differentiation control. All these results suggest that NEU3 upregulation could enhance melanoma malignancy by altering specific signaling pathways that are involved in cell motility and cell differentiation and thus NEU3 could be a novel target for treating melanoma.

Nonequilibrium self-energy functional theory

description: The self-energy functional theory (SFT) is generalized to describe the real-time dynamics of correlated lattice-fermion models far from thermal equilibrium. This is achieved by means of a reformulation of the original equilibrium theory in terms of double-time Green's functions on the Keldysh-Matsubara contour. We construct a functional which is stationary at the physical (nonequilibrium) self-energy and which yields the grand potential of the initial thermal state at the physical point. Non-perturbative approximations can be defined by specifying a reference system that serves to generate trial self-energies. These self-energies are varied by varying the reference system's one-particle parameters on the Keldysh-Matsubara contour. In case of thermal equilibrium, the new approach reduces to the conventional SFT. However, "unphysical" variations, i.e., variations that are different on the upper and the lower branch of the Keldysh contour, must be considered to fix the time-dependence of the optimal physical parameters via the variational principle. Functional derivatives in the nonequilibrium SFT Euler equation are carried out analytically to derive conditional equations for the variational parameters that are accessible to a numerical evaluation via a time-propagation scheme. Approximations constructed by means of the nonequilibrium SFT are shown to be inherently causal, internally consistent and to respect macroscopic conservation laws resulting from gauge symmetries of the Hamiltonian. This comprises the nonequilibrium dynamical mean-field theory but also dynamical-impurity and variational-cluster approximations that are specified by reference systems with a finite number of degrees of freedom. In this way, non-perturbative and consistent approximations can be set up, the numerical evaluation of which is accessible to an exact-diagonalization approach.

description: Abstract Chapter 3 Studies on university agency have been largely informed by the debate between the influence of environmental forces and important of managerial rationality, often neglecting the role of an organisational dimension. The paper starts filling this gap by investigating how this meso-level of analysis influences the processes of institutional positioning. The broad concept of organisational dimension has been operationalized through three variables: the organisational structure, identity, and centrality. Four case studies, two Italian and two English universities, have been selected to empirically examine the relationship between these three variables and positioning processes. The findings highlight how specific values of the organizational structure, identity and centrality can positively support institutional efforts like positioning. However, these relationships cannot be considered as deterministic since some potential intervening factors might, at least theoretically, modify their expected directions.

description: We prove the existence of weak solutions to the steady compressible Navier-Stokes system in the barotropic case for a class of pressure laws singular at vacuum. We consider the problem in a bounded domain in R^2 with slip boundary conditions. Due to appropriate construction of approximate solutions used in proof, obtained density is bounded away from 0 (and infinity). Owing to a classical result by P.-L. Lions, this implies that density and gradient of velocity are at least Hölder continuous, which does not generally hold for the classical isentropic model in the presence of vacuum.

We also show that some of these Riemann data are generated by a 1-dimensional compression wave: our theorem leads therefore to Lipschitz initial data for which there are infinitely many global bounded admissible weak solutions.

description: The line intensities of the fundamental rotational transitions of H13CN and HC15N were observed towards two prestellar cores, L183 and L1544, and lead to molecular isotopic ratios 140 6 14N/15N 6 250 and 140 6 14N/15N 6 360, respectively. The range of values reflect genuine spatial variations within the cores. A comprehensive analysis of the available measurements of the nitrogen isotopic ratio in prestellar cores show that molecules carrying the nitrile functional group appear to be systematically 15N-enriched com- pared to those carrying the amine functional group. A chemical origin for the differential 15N-enhance- ment between nitrile- and amine-bearing interstellar molecules is proposed. This sheds new light on several observations of Solar System objects: (i) the similar N isotopic fractionation in Jupiter's NH3 and solar wind N+; (ii) the 15N-enrichments in cometary HCN and CN (that might represent a direct inter- stellar inheritance); and (iii) 15N-enrichments observed in organics in primitive cosmomaterials. The large variations in the isotopic composition of N-bearing molecules in Solar System objects might then simply reflect the different interstellar N reservoirs from which they are originating.

description: For the evaluation of information flow in bivariate time series, information measures have been employed, such as the transfer entropy (TE), the symbolic transfer entropy (STE), defined similarly to TE but on the ranks of the components of the reconstructed vectors, and the transfer entropy on rank vectors (TERV), similar to STE but forming the ranks for the future samples of the response system with regard to the current reconstructed vector. Here we extend TERV for multivariate time series, and account for the presence of confounding variables, called partial transfer entropy on ranks (PTERV). We investigate the asymptotic properties of PTERV, and also partial STE (PSTE), construct parametric significance tests under approximations with Gaussian and gamma null distributions, and show that the parametric tests cannot achieve the power of the randomization test using time-shifted surrogates. Using simulations on known coupled dynamical systems and applying parametric and randomization significance tests, we show that PTERV performs better than PSTE but worse than the partial transfer entropy (PTE). However, PTERV, unlike PTE, is robust to the presence of drifts in the time series and it is also not affected by the level of detrending.

description: We present a statistical method based on a maximum likelihood approach to constrain the number counts of extragalactic sources below the nominal flux-density limit of continuum imaging surveys. We extract flux densities from a radio map using positional information from an auxiliary catalogue and show that we can model the number counts of this undetected population down to flux density levels well below the detection threshold of the radio survey. We demonstrate the capabilities that our method will have with future generation wide-area radio surveys by performing simulations over various sky areas. We show that it is possible to accurately constrain the number counts of the simulated distribution down to one tenth of the flux noise rms with just a sky area of 100 deg$^2$. We then test the application of our method using data from the Faint Images of the Radio Sky at Twenty-Centimeters survey (FIRST). We extract flux densities from the FIRST map, sensitive to 150 $μ$Jy/beam (1 $σ$), using the positional information from a catalogue in the same field, also acquired at the same frequency, sensitive to 12 $μ$Jy/beam (1 $σ$). Implementing our method, with known source positions, we are able to recover the right differential number counts of the noise-dominated FIRST map fluxes down to a flux density level which is one-tenth the FIRST detection threshold.

description: NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

The aim of this research was to find design data for the stiffened plywood panels supplied by the Fletcher Aviation Company.

The tests included stiffened panel tests, unstiffened panel tests, and short column tests to find the physical properties of the material.

The results of these tests, show that the ultimate compression stress which the specimen will resist is a function of the percentage stiffener area compared to the total panel area, and the [...] ratio of the panel.

Predicted ultimate stresses from the curves developed show sufficiently good agreement with actual test, that they may be used for design purposes with allowance for descrepancies in material and workmanship.

description: We examine the zero-temperature phase diagram of the two-dimensional Levin-Wen string-net model with Fibonacci anyons in the presence of competing interactions. Combining high-order series expansions around three exactly solvable points and exact diagonalizations, we find that the non-Abelian doubled Fibonacci topological phase is separated from two nontopological phases by different second-order quantum critical points, the positions of which are computed accurately. These trivial phases are separated by a first-order transition occurring at a fourth exactly solvable point where the ground-state manifold is infinitely many degenerate. The evaluation of critical exponents suggests unusual universality classes.

description: Accurate and efficient thermal simulations of induction machines are indispensable for detecting thermal hot spots and hence avoiding potential material failure in an early design stage. A goal is the better utilization of the machines with reduced safety margins due to a better knowledge of the critical conditions. In this work, the parameters of a two-dimensional induction machine model are calibrated according to evidence from measurements, by solving an inverse field problem. The set of parameters comprise material parameters as well as parameters that model three-dimensional effects. This allows a consideration of physical effects without explicit knowledge of its quantities. First, the accuracy of the approach is studied using an academic example in combination with synthetic data. Afterwards, it is successfully applied to a realistic induction machine model.
Pulsar interpretation for the AMS-02 result

description: The AMS-02 collaboration has just published a high precision measurement of the cosmic positron fraction $e^+/(e^- + e^+)$, which rises with energy from $\sim 5$ GeV to $\sim 350$ GeV. The result indicates the existence of primary electron/positron sources to account for the positron excess. In this work, we investigate the possibility that the nearby mature pulsars are the primary positron sources. By fitting the data we find that the positrons from a single nearby pulsar, such as Geminga or Monogem, with the spectral index $α\sim 2$ can interpret the AMS-02 result. We also investigate the possibility that high energy positrons are generated by multiple known pulsars in the ATNF catalogue. Such a scenario can also fit the AMS-02 data well. Future precise measurements of fine structures in the positron spectrum would be a support to the pulsar scenario.

A photoelastic investigation of the effect of elliptical and modified cutouts in flat panels subjected to combined bending and shear
Creators: name: Hanger, Willard Muirhead
Publisher: name: California Institute of Technology
Year: 1943
Subjects: Aeronautical Engineering

description: Quite frequently in an aircraft structure there are occasions when it is necessary or advantageous to make openings or cutouts in the structure. These may be lightening holes in a web or spar or they may be openings in the structure which are necessary for access or other reasons. An analytical solution of the problem of stress distribution around a cutout in a stressed member is often impossible since the analytical method is limited to problems in which the boundary conditions are simple. The purpose of this investigation was to determine by means of a photo-elastic analysis the amount of stress concentration caused by a cutout in a flat panel and how this concentration varied under different conditions of loading and with various types of cutouts. Simple photoelasticity provides a means of finding the stresses only along the cutout boundary. However since the stress concentrations are a maximen at the boundary, this is the region in which the designer is most interested. Only boundary stresses along the cutout are considered in this paper.

This research is a continuation of the work carried out by Gibbons and Dill at the California Institute of Technology in 1941-42. Their paper entitled “A Photoelastic Investigation of the Effect of Elliptical and Modified Cutouts in Flat Panels Subjected to Combined Bending and Shear” dealt with a similar panel with similar cutouts under much the same conditions of loading as carried out in this research. However the long axis of the cutout in this investigation was horizontal or perpendicular to the shear loading, while the long axis of the cutout in the previous investigation was at 90° to this direction, i.e., vertical. Tyra and Hollister also did some research at the California Institute of Technology on this subject. Their thesis entitled “A Photoelastic Investigation of the Effect of Cutouts in Panels Subjected to Combined Bending and Shear" dealt with circular and modified circular cutouts. This paper considers an elliptical cutout which was modified by several steps to a rectangular opening, the ratio  of the maximum length to width being 2:1.

description: Recent observations indicate that about half of the dwarf satellite galaxies around M31 orbit in a thin plane approximately aligned with the Milky Way. It has been argued that this observation along with several other features can be explained if these dwarf satellite galaxies originated as tidal dwarf galaxies formed during an ancient merger event. However if dark matter is collisionless then tidal dwarf galaxies should be free of dark matter - a condition that is difficult to reconcile with observations indicating that dwarf satellite galaxies are dark matter dominated. We argue that dissipative dark matter candidates, such as mirror dark matter, offer a simple solution to this puzzle.
