description: High-dimensional single-cell morphology data from large-scale microscopy drug screening applications help prioritize effective treatments for patients suffering from various diseases and enable the discovery of new biological mechanisms. Image analysis pipelines to process these single-cell data often introduce errors in the segmentation step, where software improperly segments single cells (for example, capturing undersized or overly large portions of a cell compartment) and incorrectly identifies artifacts like dust or other debris as single cells. These errors lead to erroneous single-cell measurements which need to be removed prior to single-cell analyses to help ensure accurate results. Research scientists often use bespoke approaches to filter single cells or aggregate all single cells into bulk profiles, reducing errors' impact and preventing single-cell analysis. This leads to duplicated effort, human error, and a lack of quality control in single-cell feature data which overall may result in a reduced potential for discoveries or inaccurate outcomes.

We introduce a Python package called coSMicQC (Single cell Morphology Quality Control) to improve single-cell morphology analysis. coSMicQC uses high-content morphology measurements to define default thresholds for removing single cells and enables users to customize quality control parameters. Accessible through both command line interface (CLI) and Python application programming interface (API), coSMicQC seamlessly integrates into diverse analytical workflows, including standalone scripts/workflows to interactive Jupyter Notebooks. Notably, the package creates interactive and exportable visualizations that illustrate outlier distributions. The backbone of this package is a novel data format: the CytoDataFrame. CytoDataFrames facilitate real-time exploration of single-cell images within any pandas environment to seamlessly link single-cell morphology measurements with single-cell images. Leveraging real-world datasets, including Joint Undertaking in Morphological Profiling (CPJUMP1) data, we show how our tool empowers researchers to identify technical outliers within single-cell profile features and improve single-cell analysis.

description: Co-doped BaFe2As2 (Ba-122) can be realized on both MgO and SrTiO3 bicrystal substrates with [001]-tilt grain boundary by employing Fe buffer layers. However, an additional spinel (i.e. MgAl2O4) buffer between Fe and SrTiO3 is necessary since an epitaxial, smooth surface of Fe layer can not be grown on bare SrTiO3. Both types of bicrystal films show good crystalline quality.

description: Based on the quantum electrodynamics, we present a generic formalism of the polarization for beamed monochromatic photons scattered by electrons in any spectral distribution. The formulae reduce to the components of the Fano matrix when electrons are at rest. We mainly investigate the polarization in three scenarios, i.e., electrons at rest, isotropic electrons with a power law spectrum and thermal electrons. If the incident beam is polarized, the polarization is reduced significantly by isotropic electrons at large viewing angles, and the degree of polarization due to thermal electrons is about one times less than that of electrons in a power law. If the incident bean is unpolarized, soft $γ$-rays can lead to about 15% polarization at viewing angles around $π/4$. For isotropic electrons, one remarkable feature is that the polarization as a function of the incident photon energy always peaks roughly at 1 MeV, this is valid for both the thermal and power law cases. This feature can be used to distinguish the model of the inverse Compton scattering from that of the synchrotron radiation.

Experimental study of helium and argon diffusion in the wake of a circular cylinder at M=5.8

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

Experimental measurements of the diffusion of helium and argon in the wake of a porous cylinder were made in the GALCIT hypersonic wind tunnel at Mach number 5.8. The cylinder was mounted perpendicular to the flow and small quantities of tracer gas were pumped through the model walls into the flow. The thermal conductivity method of gas analysis was used to determine the concentration of sample gases extracted from points in the wake.

The transverse and axial distribution of concentration appeared to follow theoretical estimates of "similarity behavior". Injection of tracer gas was found to have a measurable effect on stagnation pressure and this effect was taken into account during computations. Numerical values of diffusion coefficients along the wake centerline were computed from the experimental data and then compared with theoretical values for laminar flow. Close agreement between experimental and theoretical values at [...] = 18,000 verified that the inner wake was laminar as far downstream as measurements could be made (15 diameters). At [...] = 72,000, the data showed that mixing processes were 3 times more rapid for helium, and 10 times more rapid for argon, than those expected in laminar flow. This result confirmed the presence of turbulence at this flow condition.

description: Higher-order statistics are a useful and complementary tool for measuring the clustering of galaxies, containing information on the non-gaussian evolution and morphology of large-scale structure in the Universe. In this work we present measurements of the three-point correlation function (3PCF) for 187,000 galaxies in the WiggleZ spectroscopic galaxy survey. We explore the WiggleZ 3PCF scale and shape dependence at three different epochs z=0.35, 0.55 and 0.68, the highest redshifts where these measurements have been made to date. Using N-body simulations to predict the clustering of dark matter, we constrain the linear and non-linear bias parameters of WiggleZ galaxies with respect to dark matter, and marginalise over them to obtain constraints on sigma_8(z), the variance of perturbations on a scale of 8 Mpc/h and its evolution with redshift. These measurements of sigma_8(z), which have 10-20% accuracies, are consistent with the predictions of the LCDM concordance cosmology and test this model in a new way.

description: We analyze new physics contributions to $e^+e^-\to W^+W^-$ at the TeV energy scale, employing an effective field theory framework. A complete basis of next-to-leading order operators in the standard model effective Lagrangian is used, both for the nonlinear and the linear realization of the electroweak sector. The elimination of redundant operators via equations-of-motion constraints is discussed in detail. Polarized cross sections for $e^+e^-\to W^+W^-$ (on-shell) are computed and the corrections to the standard model results are given in an expansion for large $s/M^2_W$. The dominant relative corrections grow with $s$ and can be fully expressed in terms of modified gauge-fermion couplings. These corrections are interpreted in the context of the Goldstone boson equivalence theorem. Explicit new physics models are considered to illustrate the generation and the potential size of the coefficients in the effective Lagrangian. Brief comments are made on the production of $W^+W^-$ pairs at the LHC.

description: A lattice of optical ring resonators can exhibit a topological insulator phase, with the role of spin played by the direction of propagation of light within each ring. Unlike the system studied by Hafezi et al., topological protection is achieved without fine-tuning the inter-resonator couplings, which are given the same periodicity as the underlying lattice. The topological insulator phase occurs for strong couplings, when the tight-binding method is inapplicable. Using the transfer matrix method, we derive the bandstructure and phase diagram, and demonstrate the existence of robust edge states. When gain and loss are introduced, the system functions as a diode for coupled resonator modes.

One of the main methods used in the proofs is the decoupling of the walker's trace into independent excursions by means of soft local times.

description: We propose Lobachevsky boundary conditions that lead to asymptotically H^2xR solutions. As an example we check their consistency in conformal Chern-Simons gravity. The canonical charges are quadratic in the fields, but nonetheless integrable, conserved and finite. The asymptotic symmetry algebra consists of one copy of the Virasoro algebra with central charge c=24k, where k is the Chern-Simons level, and an affine u(1). We find also regular non-perturbative states and show that none of them corresponds to black hole solutions. We attempt to calculate the one-loop partition function, find a remarkable separation between bulk and boundary modes, but conclude that the one-loop partition function is ill-defined due to an infinite degeneracy. We comment on the most likely resolution of this degeneracy.

Projecting Low Dimensional Chaos from Spatio-temporal Dynamics in a Model for Plastic Instability

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We investigate the possibility of projecting low dimensional chaos from spatiotemporal dynamics of a model for a kind of plastic instability observed under constant strain rate deformation conditions. We first discuss the relationship between the spatiotemporal patterns of the model reflected in the nature of dislocation bands and the nature of stress serrations. We show that at low applied strain rates, there is a one-to-one correspondence with the randomly nucleated isolated bursts of mobile dislocation density and the stress drops. We then show that the model equations are spatiotemporally chaotic by demonstrating the number of positive Lyapunov exponents and Lyapunov dimension scale with the system size at low and high strain rates. Using a modified algorithm for calculating correlation dimension density, we show that the stress-strain signals at low applied strain rates corresponding to spatially uncorrelated dislocation bands exhibit features of low dimensional chaos. This is made quantitative by demonstrating that the model equations can be approximately reduced to space independent model equations for the average dislocation densities, which is known to be low-dimensionally chaotic. However, the scaling regime for the correlation dimension shrinks with increasing applied strain rate due to increasing propensity for propagation of the dislocation bands.

description: It is a theorem of Bers that any closed hyperbolic surface admits a pants decomposition consisting of curves of bounded length where the bound only depends on the topology of the surface. The question of the quantification of the optimal constants has been well studied and the best upper bounds to date are linear in genus, a theorem of Buser and Seppälä. The goal of this note is to give a short proof of an linear upper bound which slightly improves the best known bounds.

description: A dynamical origin of the Yukawa couplings is a promising scenario to explain the flavour puzzle. The focus of this letter is set on the role of the neutrino Majorana character: when an $O(2)_{N_R}$ flavour symmetry acts on the right-handed neutrino sector, the minimum of the scalar potential allows for large mixing angles -in contrast to the simplest quark case- and predicts a maximal Majorana phase. This leads to a strong correlation between neutrino mass hierarchy and mixing pattern. Realistic solutions point to the existence of three heavy right-handed neutrinos.

description: In conjunction with the design of the high speed Cooperative Wind Tunnel at the California Institute of Technology an aerodynamic model was built and tested. Methods of design of the contraction, working section, and diffuser are explained.

The model test showed that the working section of a wind tunnel operating at a Mach Number greater than 0.7 must have adjustable walls to maintain a constant velocity through the working section.  The unsatisfactory design of the diffuser is demonstrated by both static pressure measurements and visual observations.

A description is given of visual observations of supersonic phenomena occurring in the working section and diffuser of the model.

description: In the following paper a report of both surface and subsurface geology of the Montebello oil field is given.

First a general survey of this area was made and then a geologic map with all field data plotted was prepared. Subsurface correlations were made by use of the electrical logs (Schlumberger) and the subsurface structure was studied. Also data from previous publications and from the core samples of the older drilled oil wells in this area was utilized in preparing a structure contour map.

This area, because of its large oil fields, has been of economical importance for the last twenty years. Recently two new fields were brought in and it is estimated that these fields are going to make a new record for oil production in the state of California.

One of these new fields is on the east and somewhat to the south of the old field and the second new field is located on the southwest corner of the old field. Both of those fields are of different horizones and much deeper than the older pool.

The older field known as Montebello field is an anticline, with its axis running in an east and westerly direction. There is a major unconformity below this anticline beneath which appears the oil sands of the lower horizons of the newly discovered pools.

The nature of rocks is highly complicated and shoreline deposits ore well recognized in this area. Most of these sediments are sandstones of different characters. These sandstones get coarser and grade into conglomerates from one side and chance to silt and at some instances to a thin layer of shale.

There is a big fault in this area which cuts the upper most sediments and for which there are some surface evidences. It is shown (by use of Schlumberger methods) also that there exists another fault which cuts the axis of the new eastern field and of which there is no surface evidences.

description: A design procedure for axial flow pump impellers is presented that accounts for induced interference effects in the prediction of performance. Induced interference velocities at an impeller blade have been calculated using a three-dimensional model that includes the effects of the other blades and of the total downstream vorticity along the centerline of the pump.

The design method considers improvement of cavitation conditions by specifying the radial variation of the design parameters such that the pressure distribuions on all radial sections are similar.

Experimental work on a two-bladed impeller has yielded results that give good support to all aspects of the design procedure.

description: We study scaling of the ground-state fidelity in neighborhoods of quantum critical points in a model of interacting spinfull fermions - a BCS-like model. Due to the exact diagonalizability of the model, in one and higher dimensions, scaling of the ground-state fidelity can be analyzed numerically with great accuracy, not only for small systems but also for macroscopic ones, together with the crossover region between them. Additionally, in one-dimensional case we have been able to derive a number of analytical formulae for fidelity and show that they accurately fit our numerical results; these results are reported in the article. Besides regular critical points and their neighborhoods, where well-known scaling laws are obeyed, there is the multi-critical point and critical points in its proximity where anomalous scaling behavior is found. We consider also scaling of fidelity in neighborhoods of critical points where fidelity oscillates strongly as the system size or the chemical potential is varied. Our results for a one-dimensional version of a BCS-like model are compared with those obtained by Rams and Damski in similar studies of a quantum spin chain - an anisotropic XY model in transverse magnetic field.

Spontaneous Polarization method of electrical exploration was chosen
as the subject of this thesis. It is also known as "self potential electrical
prospecting" and "natural currents method."

The object of this thesis is to present a spontaneous polarization exploration
work done by the writer, and to apply analytical interpretation methods
to these field results.

The writer was confronted with the difficulty of finding the necessary
information in a complete paper about this method. The available papers are
all too short and repeat the usual information, giving the same examples.
The decision was made to write a comprehensive paper first, including the
writer's experience, and then to present the main object of the thesis.

The following paper comprises three major parts:

1 - A comprehensive treatment of the spontaneous polarization method.

2 - Report of the field work.

3 - Analytical interpretation of the field work results.

The main reason in choosing this subject is that this method is the
most reliable, easiest and requires the least equipment in prospecting for
sulphide orebodies on unexplored, rough terrains.

The intention of the writer in compiling the theoretical and analytical
information has been mainly to prepare a reference paper about this method.

The writer wishes to express his appreciation to Dr. G. W. Potapenko,
Associate Professor of Physics at California Institute of Technology, for
his generous help.

COMMENTS: Burns and Fay (1970), Rice (1977), McDermid and Bonner (1975), Gromov and Baranova (1981), J. E. King (1983), and Wyss (1988) considered Phoca, Pusa, Histriophoca, and Pagophilus a monophyletic group. However, Muizon (1982a) suggested that Histricophoca and Pagophilus may be more closely related to Cystophora than to Phoca (sensu stricto). Burns and Fay (1970) and McDermid and Bonner (1975) argued that these differences should be recognized only at the subgeneric level which is followed here.

description: We have investigated the strength of ultraviolet Fe II emission from quasars within the environments of Large Quasar Groups (LQGs) in comparison with quasars elsewhere, for 1.1 <= <= 1.7, using the DR7QSO catalogue of the Sloan Digital Sky Survey. We use the Weymann et al. W2400 equivalent width, defined between the rest-frame continuum-windows 2240-2255 and 2665-2695 Ang., as the measure of the UV Fe II emission. We find a significant shift of the W2400 distribution to higher values for quasars within LQGs, predominantly for those LQGs with 1.1 <= <= 1.5. There is a tentative indication that the shift to higher values increases with the quasar i magnitude. We find evidence that within LQGs the ultrastrong emitters with W2400 >= 45 Ang. (more precisely, ultrastrong-plus with W2400 >= 44 Ang.) have preferred nearest-neighbour separations of ~ 30-50 Mpc to the adjacent quasar of any W2400 strength. No such effect is seen for the ultrastrong emitters that are not in LQGs. The possibilities for increasing the strength of the Fe II emission appear to be iron abundance, Ly-alpha fluorescence, and microturbulence, and probably all of these operate. The dense environment of the LQGs may have led to an increased rate of star formation and an enhanced abundance of iron in the nuclei of galaxies. Similarly the dense environment may have led to more active blackholes and increased Ly-alpha fluorescence. The preferred nearest-neighbour separation for the stronger emitters would appear to suggest a dynamical component, such as microturbulence. In one particular LQG, the Huge-LQG (the largest structure known in the early universe), six of the seven strongest emitters very obviously form three pairings within the total of 73 members.

A study of pressure drop in helical coils
Creators: name: Dwire, O. S.
Publisher: name: California Institute of Technology
Year: 1949
Subjects: Aeronautics

description: This study was made to investigate the increase in pressure drop through a helix over that through a straight pipe and to study the variables involved. The pressure drops in ten helices and seven straight pipes were observed over a range of Reynolds Numbers.

The results indicate that the increase in pressure drop due to the helical shape is a function of tube diameter, helix diameter, relative roughness, and possibly Reynolds Number. There is some indication that relative roughness may be the most important of these variables. However, the data obtained are insufficient to justify the formulation of an empirical equation for the curvature correction.

description: We use the new ultra-deep, near-infrared imaging of the Hubble Ultra-Deep Field (HUDF) provided by our UDF12 HST WFC3/IR campaign to explore the rest-frame UV properties of galaxies at redshifts z > 6.5. We present the first unbiased measurement of the average UV power-law index, beta, for faint galaxies at z ~ 7, the first meaningful measurements of beta at z ~ 8, and tentative estimates for a new sample of galaxies at z ~ 9. Utilising galaxy selection in the new F140W imaging to minimize colour bias, and applying both colour and power-law estimators of beta, we find beta = -2.1 (+/-0.2) at z ~ 7 for galaxies with M_UV ~ -18. This means that the faintest galaxies uncovered at this epoch have, on average, UV colours no more extreme than those displayed by the bluest star-forming galaxies at low redshift. At z ~ 8 we find a similar value, beta = -1.9 (+/-0.3). At z ~ 9, we find beta = -1.8 (+/-0.6), essentially unchanged from z ~ 6 - 7 (albeit highly uncertain). Finally, we show that there is as yet no evidence for a significant intrinsic scatter in beta within our new, robust z ~ 7 galaxy sample. Our results are most easily explained by a population of steadily star-forming galaxies with either ~ solar metallicity and zero dust, or moderately sub-solar (~ 10-20%) metallicity with modest dust obscuration (A_V ~ 0.1-0.2). This latter interpretation is consistent with the predictions of a state-of-the-art galaxy-formation simulation, which also suggests that a significant population of very-low metallicity, dust-free galaxies with beta ~ -2.5 may not emerge until M_UV > -16, a regime likely to remain inaccessible until the James Webb Space Telescope.

Effects of combustion chamber blockage on bluff body flame stabilization
Creators: name: Foster, James Roger
Publisher: name: California Institute of Technology
Year: 1956
Subjects: Aeronautics

description: The necessity for stabilizing a flame in a high speed flow of combustible gas has led to extensive studies of the mechanism of flame stabilization by bluff bodies. As a result of these studies it has been found that the stability limits depend directly on a characteristic wake length and that under certain conditions this characteristic dimension depends on the square root of the flame holder scale.

In the present investigation the geometry of the flame in the stabilization region is examined by means of photographic and probing techniques. The results of the studies show conclusively that for a constant blockage ratio, the wake geometry scales linearly with flame holder size. The observed square root dependence of the characteristic wake length, and hence of the blowoff velocity is shown to be directly caused by blockage effects.

description: To solve the hierarchy problem, extra-dimensional models must explain why the new dimensions stabilize to the right size, and the known mechanisms for doing so require bulk scalars that couple to the branes. Because of these couplings the energetics of dimensional stabilization competes with the energetics of the Higgs vacuum, with potentially observable effects. These effects are particularly strong for one or two extra dimensions because the bulk-Higgs couplings can then be super-renormalizable or dimensionless. Experimental reach for such extra-dimensional Higgs `portals' are stronger than for gravitational couplings because they are less suppressed at low-energies. We compute how Higgs-bulk coupling through such a portal with two extra dimensions back-reacts onto properties of the Higgs boson. When the KK mass is smaller than the Higgs mass, mixing with KK modes results in an invisible Higgs decay width, missing-energy signals at high-energy colliders, and new mechanisms of energy loss in stars and supernovae. Astrophysical bounds turn out to be complementary to collider measurements, with observable LHC signals allowed by existing constraints. We comment on the changes to the Higgs mass-coupling relationship caused by Higgs-bulk mixing, and how the resulting modifications to the running of Higgs couplings alter vacuum-stability and triviality bounds.
