The role of organized labour in the network system of industrial governance
Creators: name: Murphy, David G.
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation examines the role of organized labour in governing relations in post- Fordist networked industrial districts within the context of three such sector-districts concentrated in the south-west corner of the Canadian province of British Columbia. It discusses the impact of this role on relational structures and behavioural patterns within these industries and on sector-district performance in the marketplace. It thereby builds upon the scholarly research which followed Piore and Sabel's (1984) popularization of the so-called neo- Marshallian Industrial Districts (MIDs) of the ‘Third Italy'. The study begins with a historical review of labour's influence on the evolution of production organization and institutional governance from the initial emergence of production for the market up to the current era. This review both demonstrates the significant influence of labour on the evolution of market oriented production regimes and provides a broader historical perspective for the analysis of the three cases. These case- studies use primary documentation and interview transcripts to expose the historical source and contemporary practice of labour's normative place in production organization and institutional governance in contemporary 'network systems of industrial governance' (Hollingsworth, Schmitter and Streeck 1994). Labour's roles in these three sector-districts are compared with each other and with an idealized network construct, both to further illuminate and explain the variable outcome and to illustrate possible avenues for institutional reform. The insight acquired into labour's role in the network model will contribute not just to a better understanding of the future of industrial relations in this emergent system. It will also contribute to the broader, related study of the nature of sociopolitical organization and institutional governance in the encompassing community.

description: A strongly interacting Fermi gas, such as that of cold atoms operative near a Feshbach resonance, is difficult to study by perturbative many-body theory to go beyond mean field approximation. Here I develop an effective field theory for the resonant superfluid based on broken symmetry. The theory retains both fermionic quasiparticles and superfluid phonons, the interaction between them being derived non-perturbatively. The theory converges and can be improved order by order, in a manner governed by a low energy expansion rather than by coupling constant. I apply the effective theory to calculate the specific heat and propose a mechanism of understanding the empirical power law of energy versus temperature recently measured in a heat capacity experiment.

description: With the aid of laboratory experiments, the cathodic passivation of molybdenum electrodes during electrical melting of glass was studied. The formation of molybdenum silicide layers does not only depend on the cathodic passivation currents, but also on time and the AC heating current density If the melt has freshly been prepared from raw materials, the molybdenum silicide layer is thinner than under otherwise same conditions. While at an AC heating current density of 1 A/cm², a cathodic current density of 3.75 mA/cm² led to Optimum layer formation, at a heating current density of 2 A/cm², higher cathodic current densities are required.

description: We examine how the randomness of behavior and the flow of information between agents affect the formation of opinions. Our main research involves the process of opinion evolution, opinion clusters formation and studying the probability of sustaining opinion. The results show that opinion formation (clustering of opinion) is influenced by both flow of information between agents (interactions outside the closest neighbors) and randomness in adopting opinions.

description: Many physical properties of high-temperature (high-Tc) superconductors are two-dimensional phenomena derived from their square planar CuO2 building blocks. This is especially true of the magnetism from the copper ions. As mobile charge carriers enter the CuO2 layers, the antiferromagnetism of the parent insulators, where each copper spin is antiparallel to its nearest neighbours1, evolves into a fluctuating state where the spins show tendencies towards magnetic order of a longer periodicity. For certain charge carrier densities, quantum fluctuations are sufficiently suppressed to yield static long-period order2,3,4,5,6, and external magnetic fields also induce such order7,8,9,10,11,12. Here we show that in contrast to the chemically-controlled order in superconducting samples, the field-induced order in these same samples is actually three-dimensional, implying significant magnetic linkage between the CuO2 planes. The results are important because they show that there are three-dimensional magnetic couplings which survive into the superconducting state, and coexist with the crucial inter-layer couplings responsible for three-dimensional superconductivity. Both types of coupling will straighten the vortex lines, implying that we have finally established a direct link between technical superconductivity, which requires zero electrical resistance in an applied magnetic field and depends on vortex dynamics, and the underlying antiferromagnetism of the cuprates.
Continuity corrections for certain perpetual American and Bermudan options on multiple assets

description: In a general Feller martingale market with several assets, the existence of optimal exercise regions for multi-dimensional Bermudan options can be established by reference to Neveu's theory of Snell envelopes -- and also, as will be shown, more directly from standard martingale arguments combined with the strong Markov property. Based on this, in the framework of a log-Lévy martingale market, explicit formulae and asymptotic results on the perpetual American-Bermudan (barrier-like) put option price difference (``continuity correction'') near the exercise boundary will be proven, under the -- of course, fairly restrictive -- assumption that the logarithmic optimal exercise region, subject to the barrier, does not depend on the time mesh size and is, up to translation, a half-space. For this sake, Wiener-Hopf type results by Feller will be generalized to higher dimensions. It will be shown that an extrapolation from the exact Bermudan prices to the American price cannot be polynomial in the exercise mesh size in the setting of many common market models, and more specific bounds on the natural scaling exponent of the non-polynomial extrapolation for a number of (both one- and multi-dimensional) market models will be deduced.

description: The changes of broad emission lines should be a crucial issue to understanding the physical properties of changing-look active galactic nucleus (CL-AGN). Here, we present the results of an intensive and homogeneous 6-month long reverberation mapping (RM) monitoring campaign during a low-activity state of the CL-AGN Seyfert galaxy NGC 3516. Photometric and spectroscopic monitoring was carried out during 2018--2019 with the Lijiang 2.4 m telescope. The sampling is 2 days in most nights, and the average sampling is $\sim$3 days. The rest frame time lags of H$α$ and H$β$ are $τ_{\rm{H}α}=7.56^{+4.42}_{-2.10}$ days and $τ_{\rm{H}β}=7.50^{+2.05}_{-0.77}$ days, respectively. From a RMS H$β$ line dispersion of $σ_{\rm{line}} = 1713.3 \pm 46.7$ $\rm{km}$ $\rm{s^{-1}}$ and a virial factor of $f_σ$ = 5.5, the central black hole mass of NGC 3516 is estimated to be $M_{\rm{BH}}= 2.4^{+0.7}_{-0.3} \times 10^{7} M_{\odot}$, which is in agreement with previous estimates. The velocity-resolved delays show that the time lags increase towards negative velocity for both H$α$ and H$β$. The velocity-resolved RM of H$α$ is done for the first time. These RM results are consistent with other observations before the spectral type change, indicating a basically constant BLR structure during the changing-look process. The CL model of changes of accretion rate seems to be favored by long-term H$β$ variability and RM observations of NGC 3516.

description: The phase Separation behaviour of industrial soda-lime-silica glass is studied by visible light scattering. The main aspects which differentiate industrial glass from the ternary glass (composition in wt%): 76 SiO₂, 13 Na₂O, 11 CaO are considered. The obtained results show that the simple ternary glass easily develops phase Separation upon annealing at suitable temperature levels. Conversely, Container glass is stabilized against demixtion by the presence of a significant AI₂O₃ concentration, a significantly lower SiO₂ content and a more complex chemical formulation (partial Substitution of SiO₂, Na₂O and CaO with AI₂O₃, K₂O and MgO, respectively, as well as minor ingredients).
Gob weight fluctuations due to a stirrer and to glass melting firing reversals

Year: 1998
Subjects: subject: 660

description: It was difficult to adjust gob weights from a stirred, molten glass delivery System. The difficulty decreased when rotation of the gobbing stirrer was stopped. However, this was not a satisfactory Solution as it left objectional striations in the glass items being produced. The weight changes were due to the superposition of several effects, each of which by itself would have been acceptable. Small temperature fluctuations and spontaneous changes in the stirrer's position and stroke were found but they were not the major causes of the weight fluctuations. Cyclic variations in weight with an amplitude of about 1% and a period of about 11 min were due to the stirrer's rotation. It became clear that close but approximate matching of the gobbing and rotational rates was inadequate and that synchronization of these two rates had to be perfect to eliminate this cyclic weight Variation. The inevitable conclusion was that run-out associated with stirring was the cause of this problem. Α second cyclic Variation with a period of 20 min and an amphtude of about 0.4% was associated with tank reversals of the cross-fired melter with its regenerative checkers. This was the first time that weight changes due to tank reversals were noted. Α composite weight Variation curve was synthesized, with one component representing an 11 min cycle and a second component representing a 20 min cycle formed by a ramp with a linear decay Α comparison of the synthesized and actual weight curves revealed many similarities and strengthened the conclusion that most of the actual weight run changes resulted from the stirrer and from tank reversals.

Experimental investigations of the internal friction of optical and technical glasses with a flexure pendulum equipment

description: Α special flexure pendulum equipment for investigation of the mechanical relaxation behaviour (internal friction) of glasses, glassceramics and other materials is presented. With the help of this apparatus it is possible to investigate the internal friction in the temperature ränge from room temperature until beyond Tg with a frequency of about 1 Hz. For analyzing the experimental results the shear behaviour of the investigated material is described in terms of a Maxwell body characterized by the rheological parameters Young's modulus and relaxation time. From the theoretical treatment of the bending problem for the experimental equipment calculation, formulae are obtained which connect the rheological parameters with the measured quantities period of oscillation and logarithmic decrement. Investigations of the internal friction of optical and technical glasses show weak effects in the ränge from room temperature until Tg and very strong damping peaks with different peak widths and maxima temperatures in the ränge beyond Tg. The syntheses and glass transformation ranges of the investigated glasses are very different. The activation energies of the hightemperature relaxation processes are obtained from the measured temperature dependences of relaxation times. These activation energies of the high-temperature relaxation process beyond Tg are smaller than the activation energies of viscosity determined by means of a bar elongation method.
Properties of textile glass fibers based on alkali- and boron oxide-free aluminosilicate glasses

description: The goal of this paper is to examine the possibihty of producing fibers from alkah- and boron oxide-free glasses with properties comparable to those of commercially available glass fibers. Various compositions from the Systems SiO₂ - Al₂O₃ - CaO - RO are investigated with RO = MgO, ZnO, MnO, BaO between 0 and 10 wt%. The fibers are suitable for application as textile fibers and as reinforcement component for composites. The mechanical properties (tensile strength, Young's and shear modulus and Poisson ratio) are comparable to and/or partly better than those of commercially produced glass fibers. The chemical resistivity in 2 mol/1 NaOH is better than that of E-glass fibers. Although the diameter of glass fibers is not the only parameter which determines fiber properties and structure, it is a very important one because it influences both the mechanical and the thermal history of the fibers. For this reason, and in order to approximate commercial fiber drawing conditions, fibers were prepared with roughly the same fiber diameters. Despite this restriction the results provide information for qualitative ratings and for relative comparison of properties and structural interpretations. Of special interest is the opposite dependence of strength and elastic moduli on the fiber diameter. This is explained by means of frozen-in orientation and deformation effects of microcracks and network anisometries due to the mechanical and thermal history of the fibers produced by the fiber drawing process.

description: [Abridged] The formation of Jupiter is modeled via core-nucleated accretion, and the planet's evolution is simulated up to the present epoch. The growth from a small embryo until gas accretion overtakes solids' accretion was presented by D'Angelo et al. (Icarus 2014, 241, 298). Those calculations followed the formation for $4\times 10^{5}$ years, until the heavy-element and H/He masses were $M_{Z}\approx 7.3$ and $M_{XY}\approx 0.15$ Earth's masses ($M_{\oplus}$), respectively, and $dM_{XY}/dt\approx dM_{Z}/dt$. The calculation is continued through the phase when $M_{XY}=M_{Z}$, at which age, about $2.4\times 10^{6}$ years, the planet mass is $M_{p}\approx 20\,M_{\oplus}$. About $9\times 10^{5}$ years later, $M_{p}$ is approximately $60\,M_{\oplus}$ and $M_{Z}\approx 16\,M_{\oplus}$. Around this epoch, the contraction of the envelope dictates gas accretion rates a few times $10^{-3}\,M_{\oplus}$ per year, initiating the regime of disk-limited accretion, when the planet's evolution is tied to disk's evolution. Growth is continued by constructing simplified models of accretion disks that evolve through viscous diffusion, winds, and accretion on the planet. Jupiter's formation ends after $\approx 3.4$-$4.2$ Myr, when nebula gas disperses. The young Jupiter is $4.5$-$5.5$ times as voluminous as it is presently and thousands of times as luminous, $\sim 10^{-5}\,L_{\odot}$. The heavy-element mass is $\approx 20\,M_{\oplus}$. The evolution proceeds through the cooling and contraction phase, in isolation except for solar irradiation. After $4570$ Myr, radius and luminosity of the planet are within $10$% of current values. During formation, and soon thereafter, the planet exhibits features, e.g., luminosity and effective temperature, that may probe aspects of the latter stages of formation, if observable. These possibly distinctive features, however, seem to disappear within a few tens of Myr.

Sulphur availability on interior lodgepole pine sites
Creators: name: Kishchuk, Barbara Ellen
Publisher: name: University of British Columbia
Year: 2009

description: Sulphur deficiencies limit the response of lodgepole pine to nitrogen fertilization on some sites in the British Columbia interior. Soil sulphur properties, foliar nutrition, and response to fertilization were investigated on sulphur-deficient and sulphur-sufficient sites. The soil sulphur constituents most closely associated with sulphur availability were determined. Cycling of soluble inorganic-sulphate through organic-sulphate in mineral soils is the process limiting sulphur availability on sulphur-deficient sites. Sulphur cycling appears to be further limited by low concentrations of organic carbon. A model containing foliar nitrogen, foliar sulphate-sulphur, and soil organic carbon concentrations was a better predictor of lodgepole pine growth response to nitrogen fertilization than a model containing only foliar nitrogen and sulphate-sulphur. Sulphur concentrations in lodgepole pine foliage remained elevated several years after fertilization with sulphate-sulphur. Soil organic-sulphate concentration increased with elemental sulphur fertilization, although seedling biomass was similar on fertilized and unfertilized soils. The susceptibility of interior lodgepole pine sites to sulphur deficiencies is related to both pedogenetic processes and management practices.

The Environment of FRB 121102 and Possible Relation to SGR/PSR J1745-2900
Creators: name: Katz, J. I.
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Variations of the dispersion (DM) and rotation (RM) measures of FRB 121102 indicate magnetic fields $\sim$ 3--17 mG in the dispersing plasma. The electron density may be $\sim 10^4\,$cm$^{-3}$. The observed time scales $\sim 1$ year constrain the size of the plasma cloud. Increasing DM excludes simple models involving an expanding supernova remnant, and the non-zero RM excludes spherical symmetry. The varying DM and RM may be attributable to the motion of plasma into or out of the line of sight or changing electron density within slower-moving plasma. The extraordinarily large RM of FRB 121102 implies an environment, and possibly also a formation process and source, qualitatively different from those of other FRB. The comparable and comparably varying RM of SGR/PSR J1745-2900 suggests it as an FRB candidate. An appendix discusses the age of FRB 121102 in the context of a "Copernican Principle".

description: We consider the capacity of classical information transfer for noiseless quantum channels carrying a finite average number of massive bosons and fermions. The maximum capacity is attained by transferring the Fock states generated from the grand-canonical ensemble. Interestingly, the channel capacity for a Bose gas indicates the onset of a Bose-Einstein condensation, by changing its qualitative behavior at the criticality, while for a channel carrying weakly attractive fermions, it exhibits the signatures of Bardeen-Cooper-Schrieffer transition. We also show that for noninteracting particles, fermions are better carriers of information than bosons.

description: The properties of the Kohn-Sham (KS) exchange potential for open systems in thermodynamical equilibrium, where the number of particles is non-conserved, are analyzed with the Optimized Effective Potential (OEP) method of Density Functional Theory (DFT) at zero temperature. The quasi two-dimensional electron gas (2DEG) is used as an illustrative example. The main findings are that the KS exchange potential builds a significant barrier-like structure under slight population of the second subband, and that both the asymptotic value of the KS exchange potential and the inter-subband energy jump discontinuously at the one-subband (1S) -> two-subband (2S) transition. The results obtained in this system offer new insights on open problems of semiconductors, such as the band-gap underestimation and the band-gap renormalization by photo-excited carriers.

description: Guided by the observed properties of hadrons I formulate a perturbative bound state method for QED and QCD. The expansion starts with valence Fock states ($e^+e^-,\ q\bar q,\ qqq,\ gg$) bound by the instantaneous interaction of temporal gauge ($A^0=0$). The method is tested on Positronium atoms at rest and in motion, including hyperfine splitting at $O(α^4)$, electromagnetic form factors and deep inelastic scattering. Relativistic binding is studied for QED in $D=1+1$ dimensions, demonstrating the frame independence of the DIS electron distribution and its sea for $x_{bj} \to 0$. In QCD a homogeneous solution of Gauss' constraint in $D=3+1$ implies $O(α_s^0)$ confining potentials for $q\bar q,\ q\bar qg,\ qqq$ and $gg$ states, whereas $q\bar q\,q\bar q$ is unconfined. Meson states lie on linear Regge trajectories and have the required frame dependence. A scalar bound state with vanishing four-momentum causes spontaneous chiral symmetry breaking when mixed with the vacuum. These lecture notes assume knowledge of field theory methods, but not of bound states. Brief reviews of existing bound state methods and Dirac electron states are included. Solutions to the exercises are given in the Appendix.

description: A filtration procedure was developed to measure the reversibility of fouling during cross-flow filtration based on the square wave of applied pressure. The principle of this method, the apparatus required, and the associated mathematical relationships are detailed. This method allows for differentiating the reversible accumulation of matter on, and the irreversible fouling of, a membrane surface. Distinguishing these two forms of attachment to a membrane surface provides a means by which the critical flux may be determined. To validate this method, experiments were performed with a latex suspension at different degrees of destabilization (obtained by the addition of salt to the suspension) and at different cross-flow velocities. The dependence of the critical flux on these conditions is discussed and analysed through the osmotic pressure of the colloidal dispersion.

Unique Method for Simulation of Bolt Pre-Load

description: This paper describes the modelling approach for simulating bolt pre-loads when there is interference in the bolt-nut CAD or in the FE model. In general, the Bolt and Nut will have interference in the CAD at the thread region during the CAD modelling. When it comes to simulation, either interference regions are de-featured or ignored. There will always be a question on the validity of results when assumptions like beams with rigid elements or bonded contacts are used for simulating the bolts with preloads. The proposed beam with thermal expansion (BTE) has the advantage of using the actual 3d bolt and nut geometry even when there is CAD interference. The method ensures that the contact area and the relative movements between the components are captured as-it-is in the actual scenario. It is specifically very useful in the bolt overload clamping simulations. BTE method can also be used in various other load cases scenarios like Load by Force, displacement and Moment. This method is successfully followed in various automotive projects and has shown good co-relation between the test results and the simulation results.

description: The introduction of non-Hermiticity has greatly enriched the research field of traditional condensed matter physics, and eventually led to a series of discoveries of exotic phenomena. We investigate the effect of non-Hermitian imaginary hoppings on the attractive Hubbard model. The exact bound-pair solution shows that the electron-electron correlation suppresses the non-Hermiticity, resulting in off-diagonal long-range order (ODLRO) ground state. In a large negative $U $ limit, the ODLRO ground state corresponds to $η$-spin ferromagnetic states. We also study the system with mixed hopping configuration. The numerical result indicates the existence of the transition from normal to $η$-pairing ground states by increasing the imaginary hopping strength. Our results provide a promising approach for the non-Hermitian strongly correlated system.

description: The site characteristics, traffic control used, and accidents occurring at 65 rural, high-speed intersections were summarized. The differences resulting when the right of way is controlled by stop signs versus a traffic signal are discussed. The factors contributing to the accidents as well as the characteristics of the accidents were analyzed. The data obtained at each intersection were summarized and recommendations, which could be used as a guide for implementing changes at other similar intersections, were made for the study locations. The accident analysis shows that providing the driver adequate warning of the intersection is of primary importance for this type of intersection. At signalized intersections, the need to provide a proper change interval and maximize the visibility of the signal heads are essential. The need to consider separate left-turn phasing also is shown.

description: Normal state orbital diamagnetism of charged bosons quantitatively accounts for recent high-resolution magnetometery results near and above the resistive critical temperature Tc of superconducting cuprates. Our parameter-free descriptions of normal state diamagnetism, Tc, upper critical fields and specific heat anomalies unambiguously support the 3D Bose-Einstein condensation at Tc of preformed real-space pairs with zero off-diagonal order parameter above Tc, at variance with phase fluctuation (or vortex) scenarios of the "normal" state of cuprates.

description: We investigate some analytical properties of loop group models, showing that a Positive Energy Representation (PER) of a loop group $LG$ can be extended to a PER of $H^{3/2}(S^1,G)$ for any compact, simple and simply connected Lie group $G$. We then explicitly compute the adjoint action of $H^{5/2}(S^1,G)$ on the stress energy tensor and we use these results to prove the Quantum Null Energy Condition (QNEC) and the Bekenstein Bound for states obtained by applying a Sobolev loop to the vacuum. We also give a simpler proof of these last results in the case $G=SU(n)$. Finally, we construct and study solitonic representations of the loop group conformal nets induced by the conjugation by a loop with a discontinuity in $-1$.

description: Three different areas of roadway delineation were included in this study. These areas were:      Lane delineation materials,     crosswalk delineation materials, and     snowplowable markers.  Evaluation of lane delineation materials revealed that expanded use was warranted for polyester paint and extruded thermoplastic. The alkyd-resin extruded thermoplastic material was determined to be the most cost-effective material for crosswalk and stop bar installations. Durability and reflectivity results show that Stimsonite 96 markers have performed effectively as snowplowable markers while the recessed markers have performed effectively except on certain interstate locations.
ОСОБЕННОСТИ ЖАНРА СЕМЕЙНОЙ ХРОНИКИ В ПРОИЗВЕДЕНИЯХ ДИНЫ РУБИНОЙ

description: В статье рассматривается жанровое своеобразие трилогии Дины Рубиной «Русская канарейка». Исследователи уже не раз указывали на то, что данную трилогию можно отнести к жанру семейной хроники, поскольку в произведениях использован характерный для семейной хроники хронотоп. Его специфику составляет использование локуса «дома» как символа единения семьи и выделение структурирующей повествование функции художественного времени. Однако вопрос о жанровом своеобразии этого произведения скорее поставлен, нежели решен, что подчеркивает своевременность предпринятого нами исследования.
Reparametrization modes in 2d CFT and the effective theory of stress tensor exchanges

description: We study the origin of the recently proposed effective theory of stress tensor exchanges based on reparametrization modes, that has been used to efficiently compute Virasoro identity blocks at large central charge. We first provide a derivation of the nonlinear Alekseev--Shatashvili action governing these reparametrization modes, and argue that it should be interpreted as the generating functional of stress tensor correlations on manifolds related to the plane by conformal transformations. In addition, we demonstrate that the rules previously prescribed with the reparametrization formalism for computing Virasoro identity blocks naturally emerge when evaluating Feynman diagrams associated with stress tensor exchanges between pairs of external primary operators. We make a few comments on the connection of these results to gravitational theories and holography.

description: This paper derives expressions for the critical current at the onset of spin-transfer-torque (STT) instability in CPP-GMR read heads, as a function of the relative angle (theta) between the free and reference layer magnetizations. Including a general angular dependent STT coefficient B(q=cos(theta)) exclusive of the angular momentum conserving sin(theta) factor, the critical current is found to depend on both B(q) and dB/dq in the non-collinear case |q| < 1. The paper also details the experimental measurement of the angular dependent critical currents on 50-nm sized CPP-GMR devices with synthetic antiferromagnet pinned layers, and fabricated using e-beam lithography. The measurements are consistent with prior theoretical models of the form B(q) ~ 1/[1+cnst*q], and indicate perhaps unanticipated implications for read head operation due to the critical current dependence on dB/dq.

description: The objectives of this study were to evaluate available foil-back and removable tapes as well as construction-zone raised pavement markers and to recommend materials that should be included on approved lists for use by the Kentucky Department of Highways. Tapes and markers were placed on transverse test sections and the reflectivity, durability, and appearance were observed.  Tapes to be included on the approved lists for foil-back and removable tapes were recommended. Tapes manufactured by 3M, Flex-O-Lite, Cataphote, and Swarolite were included on the list of acceptable foil-back tapes. Recommended removable tapes were the 3M and Cataphote removable tapes. Stimsonite 66 and Flex-O-Lite construction-zone markers were included on the approved list for construction-zone raised pavement markers.  More specific guidelines were developed to use in future evaluations of construction-zone preformed tape and markers.
Measurements of Neutral B Decay Branching Fractions to K0S pi+ pi- Final States and the Charge Asymmetry of B0 --> K*+ pi-

description: We analyze the decay B0 -> K0s pi+ pi- using a sample of 232 million Upsilon(4S) -> BB decays collected with the BaBar detector at the SLAC PEP-II asymmetric-energy B factory. A maximum likelihood fit finds the following branching fractions: BF(B0 -> K0 pi+ pi-) = (43.0 +/- 2.3 +/- 2.3) x 10^{-6}, BF(B0 -> f0 (-> pi+ pi-) K0) = (5.5 +/- 0.7 +/- 0.5 +/- 0.3) x 10^{-6} and BF(B0 -> K*+ pi-) = (11.0 +/- 1.5 +/- 0.5 +/- 0.5) x 10^{-6}. For these results, the first uncertainty is statistical, the second is systematic, and the third (if present) is due to the effect of interference from other resonances. We also measure the CP-violating charge asymmetry in the decay B0 -> K*+ pi-, A(B0 -> K*+ pi-) = -0.11 +/- 0.14 +/- 0.05.

description: Kentucky has a systematic procedure to identify locations that have abnormal rates or numbers of accidents. This procedure utilizes average accident rates and numbers. A primary objective of this study was to determine average accident statistics in Kentucky. An annual safety program for Kentucky, which includes the identification, programming, budgeting, and evaluation of safety projects, is prepared each year. The data presented in this report may be included as the problem identification portion of Kentucky's Annual Highway Safety Plan.  Average and critical accident rates were calculated by highway type for rural and urban highways. A summary of results and recommendations in several problem identification areas is presented, These general areas include alcohol, occupant protection, speed, pedestrians, bicycles, and vehicle defects.

description: Image classification in the open-world must handle out-of-distribution (OOD) images. Systems should ideally reject OOD images, or they will map atop of known classes and reduce reliability. Using open-set classifiers that can reject OOD inputs can help. However, optimal accuracy of open-set classifiers depend on the frequency of OOD data. Thus, for either standard or open-set classifiers, it is important to be able to determine when the world changes and increasing OOD inputs will result in reduced system reliability. However, during operations, we cannot directly assess accuracy as there are no labels. Thus, the reliability assessment of these classifiers must be done by human operators, made more complex because networks are not 100% accurate, so some failures are to be expected. To automate this process, herein, we formalize the open-world recognition reliability problem and propose multiple automatic reliability assessment policies to address this new problem using only the distribution of reported scores/probability data. The distributional algorithms can be applied to both classic classifiers with SoftMax as well as the open-world Extreme Value Machine (EVM) to provide automated reliability assessment. We show that all of the new algorithms significantly outperform detection using the mean of SoftMax.

description: In this work we present the first steps towards benchmarking isospin symmetry breaking in ab initio nuclear theory for calculations of superallowed Fermi $β$-decay. Using the valence-space in-medium similarity renormalization group, we calculate b and c coefficients of the isobaric multiplet mass equation, starting from two different Hamiltonians constructed from chiral effective field theory. We compare results to experimental measurements for all T=1 isobaric analogue triplets of relevance to superallowed $β$-decay for masses A=10 to A=74 and find an overall agreement within approximately 250 keV of experimental data for both b and c coefficients. A greater level of accuracy, however, is obtained by a phenomenological Skyrme interaction or a classical charged-sphere estimate. Finally, we show that evolution of the valence-space operator does not meaningfully improve the quality of the coefficients with respect to experimental data, which indicates that higher-order many-body effects are likely not responsible for the observed discrepancies.
