Subjects: subject: High Energy Physics - Theory (hep-th)

description: We show that there is a set of transformations that relates all of the 24 dimensional even self-dual (Niemeier) lattices, and also leads to non-lattice objects that however cannot be interpreted as a basis for the construction of holomorphic conformal field theory. In the second part of this paper, we extend our observations to higher dimensional conformal field theories build on extremal partition functions, where we generate c=24k theories with spectra decomposable into the irreducible representations of the Fischer-Griess Monster. We observe interesting periodicities in the coefficients of extremal partition functions and characters of the extremal vertex operator algebras.

description: The charge reduction effect, produced by the nonlinear Debye screening of high-Z charges occuring in strongly-coupled plasmas, is investigated. An analytic asymptotic expression is obtained for the charge reduction factor which determines the Debye-Hueckel potential generated by a charged test particle. Its relevant parametric dependencies are analyzed and shown to predict a strong charge reduction effect in strongly-coupled plasmas.

description: We attempt to prove the existence of Reeh-Schlieder states on curved spacetimes in the framework of locally covariant quantum field theory using the idea of spacetime deformation and assuming the existence of a Reeh-Schlieder state on a diffeomorphic (but not isometric) spacetime. We find that physically interesting states with a weak form of the Reeh-Schlieder property always exist and indicate their usefulness. Algebraic states satisfying the full Reeh-Schlieder property also exist, but are not guaranteed to be of physical interest.

description: The maximum traveling salesman problem (Max TSP) consists of finding a Hamiltonian cycle with the maximum total weight of the edges in a given complete weighted graph. This problem is APX-hard in the general metric case but admits polynomial-time approximation schemes in the geometric setting, when the edge weights are induced by a vector norm in fixed-dimensional real space. We propose the first approximation scheme for Max TSP in an arbitrary metric space of fixed doubling dimension. The proposed algorithm implements an efficient PTAS which, for any fixed $\varepsilon\in(0,1)$, computes a $(1-\varepsilon)$-approximate solution of the problem in cubic time. Additionally, we suggest a cubic-time algorithm which finds asymptotically optimal solutions of the metric Max TSP in fixed and sublogarithmic doubling dimensions.

description: Using the Keldysh technique, we derive a set of quasiclassical equations for Bloch electrons in noncentrosymmetric crystals upon excitation with quasimonochromatic radiation in the presence of external electrical and magnetic fields. These equations are the analog to the semiconductor-Bloch-equations for the dynamics of electrons including the photogalvanic effect (PGE) in particular the shift mechanism. The shift PGE was recently identified as showing promise for the development of new photovoltaic materials. In addition, our theory may be useful to investigate the interplay between breaking time-reversal symmetry and topological properties as well as the analysis of recent local excitation experiments in nanophotonics. Explicit results for the photogalvanic tensors are presented for linear and circular polarized light and a magnetic field. In addition, we disprove existing statements that the shift-photogalvanic effect does not contribute to the photo-Hall current.

description: Microorganisms often perform chemotaxis, (i.e., sensing and moving toward a region with a higher concentration of an attractive chemical) by changing the rate of tumbling for random walk. We studied several models with internal adaptive dynamics numerically to examine the validity of the condition for chemotaxis proposed by Oosawa and Nakaoka, which states that the time scale of tumbling frequency is smaller than that of adaptation and greater than that of sensing. Suitably renormalizing the timescales showed that the condition holds for a variety of environments and for both short- and long-term behavior.

description: The established view on oligopolistic competition with environmental externalities
has it that, since firms neglect the external effect, their incentive
to invest in R&D for pollution abatement is nil unless they are subject to
some form of environmental taxation. We take a dynamic approach to this
issue, using a simple differential game to show that the conclusion reached
by the static literature is not robust, as the introduction of dynamics shows
that firms do invest in R&D for environmental-friendly technologies throughout
the game. Moreover, our setup also illustrates the existence of multiple
equilibria, only one of which is identified by the corresponding static game.

Genetic Information: Comparing Alternative Regulatory Approaches when Prevention Matters

Subjects: SECS-P/01 Economia politica

description: We compare the alternative approaches for regulating genetic information
in the health insurance market when prevention measures are available.
In the model, firms offer insurance contracts to consumers who are
initially uninformed of their risk type but can obtain such information
by performing a costless genetic test. A crucial ingredient of our analysis
is that information has decision-making value since it allows for optimal
choice of a self-insurance action (secondary prevention). We focus on the
welfare properties of market equilibria obtained under the different regulatory
schemes and, by using an intuitive graphical analysis, we rank them
unambiguously.
Our results show that Disclosure Duty weakly dominates the other
regulatory schemes and that Strict Prohibition represents the worst regulatory
approach.

Kinetics study of hybridoma growth and antibody production
Creators: name: Henry, Olivier
Publisher: name: University of British Columbia
Year: 2009

description: Monoclonal Antibodies (MAb) produced by hybridomas have an expanding market for use in diagnostic assays, affinity separations and therapeutic applications. The objectives of this thesis were to study the kinetics of growth and antibody production of a hybridoma cell line in five different modes of operation and establish to what extent these kinetics are comparable from one mode to another. Hybridoma cells producing monoclonal antibodies were grown in batch, fed-batch, semi-continuous, continuous and perfusion cultures. The kinetics were compared in terms of growth rate, nutrient consumption rate and antibody formation rate. Batch cultures reached a maximum cell concentration of around 3x106 cells/mL and antibody concentration of 100 |j,g/mL. Glutamine was likely the substrate limiting the batch cultures since its depletion coincided with the end of exponential growth phase. No other amino acid was consumed completely and the levels of toxic metabolites (23 mM lactate; 2.6 mM ammonium) were much lower than those reported to affect growth or MAb production. A simple unstructured model was developed based on the batch data during the exponential phase. Simulations were performed and compared with experimental results obtained in semicontinuous and continuous cultures at dilution rates varying from 0.016 to 0.036 h"1. Cell yields from glucose in batch exponential phase were approximately 30% less than in the continuous processes. The cell specific glucose and glutamine uptake rates increased at greater dilution rates in both continuous and daily fed semi-continuous cultures. Comparing the cultures on the basis of specific dilution rates, perfusion results were in good agreement with semi-continuous and continuous data in terms of glutamine and glucose uptake rates. Although the specific antibody production rate only varied within a narrow range (0.7 to 2 pg/cell.h), the data suggest that the formation of antibody was growth-associated. It is concluded that modeling and analysis of semi-continuous data can describe continuous processes sufficiently well to be a useful tool for perfusion system optimization, while providing the relative simplicity of batch operation. In fed-batch, through the daily addition of a concentrate feed, cultures yielded antibody concentrations two times greater (200 (Xg/mL) compared to batch. This increase in final antibody concentration was closely related to the increase in the viable cell index.

Proposal for entangling gates on fluxonium qubits via a two-photon transition

description: We propose a family of microwave-activated entangling gates on two capacitively coupled fluxonium qubits. A microwave pulse applied to either qubit at a frequency near the half-frequency of the $|00\rangle - |11\rangle$ transition induces two-photon Rabi oscillations with a negligible leakage outside the computational subspace, owing to the strong anharmonicity of fluxoniums. By adjusting the drive frequency, amplitude, and duration, we obtain the gate family that is locally equivalent to the fermionic-simulation gates such as $\sqrt{\rm SWAP}$-like and controlled-phase gates. The gate error can be tuned below $10^{-4}$ for a pulse duration under 100 ns without excessive circuit parameter matching. Given that the fluxonium coherence time can exceed 1 ms, our gate scheme is promising for large-scale quantum processors.

Are we far from testing general relativity with the transiting extrasolar planet HD 209458b `Osiris'?

description: In this paper we investigate the possibility of measuring the general relativistic gravitoelectric contribution P^(GE) to the orbital period P of the transiting exoplanet HD 209458b 'Osiris'. It turns out that the predicted magnitude of such an effect is \sim 0.1 s, while the most recent determinations of the orbital period of HD 209458b with the photometric transit method are accurate to \sim 0.01 s. The present analysis shows that the major limiting factor is the \sim 1 m s^-1 sensitivity in the measurement of the projected semiamplitude of the star's radial velocity K. Indeed, it affects the determination of the mass m of the planet which, in turn, induces a systematic error in the Keplerian period P^(0) of \sim 8 s. It is of crucial importance because P^(0) should be subtracted from the measured period in order to extract the relativistic correction. The present-day uncertainty in $m$ does not yet make necessary the inclusion of relativistic corrections in the data-reduction process of the determination of the system's parameters. The present situation could change only if improvements of one-two orders of magnitude in the ground-based Doppler spectroscopy technique occurred.

ESTONIA • 1 spec.; Kohila quarry; Kõrgessaare Formation, Vormsi Regional Stage; TUG 42-417.
Description
The specimen is a ca 75 mm long fragment of a curved body chamber with external sculpture partly preserved. The original diameter was larger than 35 mm. The fragment is annulated with ca 4–5 regularly spaced annulations per distance equal to the corresponding conch diameter. The annulations are relatively shallow. Additionally, the conch is ornamented with numerous fine longitudinal lirae and subordinate transverse growth lines, producing a reticulate pattern. The longitudinal and transverse lirae are ca 1 mm distant.
Remarks
The ornamentation of this fragment is similar to other species of Gorbyoceras. Its curved, relatively large body chamber (conch diameter> 35 mm) is similar to G. textumaraneum, from which it differs by its fine reticulate ornamentation. The fragmentary preservation of this specimen does not permit a species level determination.

description: In three dimensions, there are two types of ${\cal N}=2$ anti-de Sitter (AdS) supersymmetry, which are denoted (1,1) and (2,0). They are characterised by different supercurrents and support different families of higher-spin gauge models (massless and massive) which were constructed in arXiv:1807.09098 and arXiv:1809.00802 for the (1,1) and (2,0) cases, respectively, using superspace techniques. It turns out that the precise difference between the (1,1) and (2,0) higher-spin supermultiplets can be pinned down by reducing these gauge theories to (1,0) AdS superspace. The present paper is devoted to the $(1,1) \to (1,0)$ AdS superspace reduction. In conjunction with the outcomes of the $(2,0) \to (1,0)$ AdS superspace reduction carried out in arXiv:1905.05050, we demonstrate that every known higher-spin theory with (1,1) or (2,0) AdS supersymmetry decomposes into a sum of two off-shell (1,0) supermultiplets which belong to four series of inequivalent higher-spin gauge models. The latter are reduced to components.

description: This report has been prepared as a sequence to the author's publication entitled, "Experimental Paving Projects using Curtiss-Wright's Coal-Modified, Coal-Tar Binder (Construction Phase)."  The previous study was concerned with the selection of test sites, the construction of the test and control sections, and the laboratory investigation performed before and d uring the construction period. This project started in April, 1959, when the Curtiss-Wright Corporation announced the development of a new and superior road-paving binder utilizing bituminous coal. The development was the result of their research program conducted in an effort to find new uses for coal and coal products.

description: We report the discovery of PSR J1906+0746, a young 144-ms pulsar in a highly relativistic 3.98-hr orbit with an eccentricity of 0.085 and expected gravitational wave coalescence time of 300 Myr. The new pulsar was found during precursor survey observations with the Arecibo 1.4-GHz feed array system and retrospectively detected in the Parkes Multibeam plane pulsar survey data. From radio follow-up observations with Arecibo, Jodrell Bank, Green Bank, and Parkes, we have measured the spin-down and binary parameters of the pulsar and its basic spectral and polarization properties. We also present evidence for pulse profile evolution, which is likely due to geodetic precession, a relativistic effect caused by the misalignment of the pulsar spin and total angular momentum vectors. Our measurements show that PSR J1906+0746 is a young object with a characteristic age of 112 kyr. From the measured rate of orbital periastron advance 7.57+/-0.03 deg/yr, we infer a total system mass of 2.61+/-0.02 Msun. While these parameters suggest that the PSR J1906+0746 binary system might be a younger version of the double pulsar system, intensive searches for radio pulses from the companion have so far been unsuccessful. It is therefore not known whether the companion is another neutron star or a massive white dwarf. Regardless of the nature of the companion, a simple calculation suggests that the Galactic birth rate of binaries similar to PSR J1906+0746 is 60/Myr. This implies that PSR J1906+0746 will make a significant contribution to the computed cosmic inspiral rate of compact binary systems.

Analysis of Pavement Roughness

Year: 1961
Subjects: subject: Transportation Engineering

description: In earlier progress reports dealing with the development of triaxial acceleration analysis as applied to the evaluation of pavement riding qualities, of which this report is a continuation, riding comfort or discomfort was emphasized. The accelerations monitored then were evaluated in terms of g's per sec., or "jerk" which is considered by some authorities to be a more significant index of comfort. The earlier methods of analysis have been reviewed, and acceleration is considered here to be the most practical parameter to use as a measure of pavement roughness. Most of the equipment and instrumentation has been retained, and the recording of triaxial accelerations has been continued. However, only accelerations in the vertical direction are considered in the present method of analysis.  In the summer of 1957, some 265 miles of bituminous concrete pavements were recorded and analyzed as part of a study on flexible pavement design. Since then, some 1000 additional miles of bituminous and portland cement concrete pavements have been tested. These include some older pavements, newly constructed pavements, and Inter-state sections thus far completed. Some of the roads have been re-tested periodically. These roads represent a cross section of Kentucky pavements and give an indication of the status of pavement roughness from the standpoint of workmanship on new pavements, rate of deterioration, and the effects of re-surfacing.

Year: 1961
Subjects: subject: Transportation Engineering

description: In co-operation with the Bureau of Public Roads, a number of reinforced pipe culvert installations in a number of states have been selected to evaluate the effectiveness of the design and construction criteria. One particular pipe has been chosen for this special study because of its installation conditions. This pipe is located on I 75-6 (5) 123 in Scott County at Station 37 + 50, US460, SW Ramp, and has been constructed using both type beddings that are specified in the 1956 edition of the Kentucky Department of Highways Standard Specifications for Road and Bridge Construction and amendments thereto. Observation of the performance of this installation during construction and after completion was desirable so as to check the validity of the theory as applied to rock fill material, which was used in this particular installation. The ultimate objective of this study and investigation, therefore, is to align the theory more with actual field conditions. No attempt has been made to discuss the hydraulic or functional phase of culvert design or the structural design of the conduit.

description: Efficient allocation of water requires knowledge of water's value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component.

Proposed Special Specification for Sand Asphalt, Skid-Resistant, Wearing Course
Creators: name: Havens, James H.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1961
Subjects: subject: Transportation Engineering

description: Because of the prominence that natural, sandstone, rock asphalt enjoyed in Kentucky during the past 50 years, sand-asphalts and sheet-asphalt mixes have not been used very extensively for paving in Kentucky. This is somewhat unfortunate because the natural, sand stone, rock asphalt has not been available since about 1955 and because there is now a need for a fine-textured, skid-resistance, wearing course for resurfacing work as well as on new pavements. These circumstances, coupled with the realization (1953-54) that surface courses and chip seals using 100% limestone aggregates tend to become slick, have emphasized the need for specifications for sand-asphalts. Further, it was in the interest of "building in" skid-resistance (about 1954) that Class I, Type B, surface was required to contain 50% siliceous, river sand for work on all roads having more than 700 vpd. Class I, Type B surface is normally laid 1-1/4 inches in depth -- which would be equivalent to about 65 lbs. of river sand per sq. yd. This sometimes requires that river sands be transported into areas where manufactured limestone sands might otherwise be more economically available. Whereas the river sands are sought for the skid-resistance which they impart to the surface, river sands are notably deficient in fine sizes (filler) which impart stability and integrity to the mix.

description: Four years of televising a university course for delivery to an audience of agricultural producers provides some reflections on the feasibility of combining traditional classroom instruction with in-depth extension educational programs. There are a sizable number of active agricultural producers who are eager to study academic topics in greater depth than could be obtained in traditional workshops or seminars. It seems possible to overcome many obstacles that earlier suggested distance education via television was not feasible from an administrative, budgetary or client acceptance point of view. The results seem worth the effort, with the providing institution benefiting from increased national recognition.

description: The Papers document Uldall's research on languages of Northern California based on fieldwork conducted while a visiting scholar at the University of California, Berkeley from 1930-1932. Although the word "Maidu" appears in the titles of many items in the collection, Uldall worked primarily on Nisenan (Southern Maidu) with speaker William Joseph, and it is likely that these materials are based on Nisenan rather than the language commonly known as Maidu today (i.e., Northeastern or Mountain Maidu). The bulk of the collection consists of Uldall's notes and drafts of a grammar of Maidu (Nisenan) and a collection of Nisenan texts that were eventually published through the efforts of William Shipley. Also included in the collection are Uldall's original field notes on Achumawi, a set of Karuk texts, notes on the phonology of Eastern Pomo and a short Nez Perce text. His Achumawi consultants were Jack Folsom, Artie Griffith, and a speaker identified only as "Jessie"; a speaker "Hattie" is identified in his Karuk notes.

description: Riparian vegetation experiences a little spatial distance humidity gradient, especially in the hyper-humid tropics. In Borneo, with almost no seasons and rather constant local climatic conditions, the riparian plant species show a wide range of morphological and physiological adaptations. This study assesses the adaptation strategies of ferns along a riparian humidity gradient in the submontane forest of Sarawak, Malaysia (Borneo). The species richness and cover, morphological traits, leaf area, leaf perimeter, leaf dissection, leaf elongation ratio, and stomatal density of 63 fern species were surveyed in six study areas along six stream transects. Significant trends in species richness and species cover were identified along the six transects, and changes in morphological traits such as leaf area, leaf perimeter, and leaf dissection were also discovered. With increasing distance from the streams (i.e. decreasing humidity), ferns tended to show longer leaves and a lower stomatal density. We conclude that the morphological traits of fronds change significantly within a short tropical riparian humidity gradient. This reveals variations in the energy investment and adaptation efficiency of ferns within a tropical forest microsite.

Fault detection and isolation using the local approach

description: Fault detection and isolation (FDI) has become a crucial issue for industrial process monitoring in order to increase availability, reliability, and production safety. Model-based FDI methods rely on the mathematical model and input-output data of a process to perform detection. The local approach is a new model-based FDI method which aims to detect slight changes of parametric properties of a system. This thesis mainly addresses to the application of FDI using the local approach. Robustness with respect to model uncertainties is an important issue for the local approach. A new algorithm was proposed to recalculate threshold based on the original threshold and covariance matrix of the estimated parameters in order to reduce false alarms due to the estimation error of process parameters. A similar algorithm was also provided to recalculate threshold to reduce fault alarms due to regular parameter fluctuations. As fault detection algorithms are often applied to closed-loop data, closed-loop fault detection was also investigated. Two methods were proposed to deal with the relevance between system input and output data in closed-loop detection: the dimension reduction method and the indirect detection method. The dimension reduction method uses a linear transformation to reduce the dimension of the normalized residual so that the covariance matrix of the revised normalized residual has full rank. The indirect detection method uses the closed-loop model to calculate the primary residual and the normalized residual. By detecting the changes of the closed-loop parameters, the method also detects the changes of the open-loop parameters. Simulation results show that both of these methods can detect changes of every single parameters of a system. Industrial data from a cross-direction (CD) control system in a paper machine was also used to assess the applicability of the local approach. By dividing the CD databox into small sections, the sensitivity of the detection algorithm was improved and the algorithm successfully detected abrupt faults of a single actuator. However, incipient faults of a single actuator can not be detected due to noise and inaccuracy of the process model.

description: In dark energy models of scalar-field coupled to a barotropic perfect fluid, the existence of cosmological scaling solutions restricts the Lagrangian of the field $\vp$ to $p=X g(Xe^{λ\vp})$, where $X=-g^{μν} \partial_μ\vp \partial_ν\vp /2$, $λ$ is a constant and $g$ is an arbitrary function. We derive general evolution equations in an autonomous form for this Lagrangian and investigate the stability of fixed points for several different dark energy models--(i) ordinary (phantom) field, (ii) dilatonic ghost condensate, and (iii) (phantom) tachyon. We find the existence of scalar-field dominant fixed points ($Ω_\vp=1$) with an accelerated expansion in all models irrespective of the presence of the coupling $Q$ between dark energy and dark matter. These fixed points are always classically stable for a phantom field, implying that the universe is eventually dominated by the energy density of a scalar field if phantom is responsible for dark energy. When the equation of state $w_\vp$ for the field $\vp$ is larger than -1, we find that scaling solutions are stable if the scalar-field dominant solution is unstable, and vice versa. Therefore in this case the final attractor is either a scaling solution with constant $Ω_\vp$ satisfying $0

description: The helix is a ubiquitous motif for biopolymers. We propose a heuristic, entropically based model that predicts helix formation in a system of hard spheres and semiflexible tubes. We find that the entropy of the spheres is maximized when short stretches of the tube form a helix with a geometry close to that found in natural helices. Our model could be directly tested with wormlike micelles as the tubes, and the effect could be used to self-assemble supramolecular helices.

description: This study, based on the data of China’s agricultural census of 1997, focuses on the land distribution among rural households and its effects on crop production structure and employment of labor and capital. The Census data show that the size of holdings surprisingly differs among households, and land rental activities has started to play an important role in land allocation. Grain production accounts for 80% of total sown area for each household group, indicating that self-sufficiency in grains production is still an important factor to farmers. Family members are a dominant source for China's agricultural labor force, regardless of the size of land held in each household. Machinery use in crop production is still not popular, while the scale of land held by households has an impact on the use of machinery in crop production. Moreover, the small land holdings of agriculture may lower labor productivity, even though there are more non-agricultural employment activities among these small scale households.

description: Numerous conceptually important quantum algorithms rely on a black-box device known as an oracle, which is typically difficult to construct without knowing the answer to the problem that the algorithm is intended to solve. A notable example is Grover's search algorithm. Here we propose a Grover search for solutions to a class of NP-complete decision problems known as subset sum problems, including the special case of number partitioning. Each problem instance is encoded in the couplings of a set of qubits to a central spin or boson, which enables a realization of the oracle without knowledge of the solution. The algorithm provides a quantum speedup across a known phase transition in the computational complexity of the partition problem, and we identify signatures of the phase transition in the simulated performance. Whereas the naive implementation of our algorithm requires a spectral resolution that scales exponentially with system size for NP-complete problems, we also present a recursive algorithm that enables scalability. We propose and analyze implementation schemes with cold atoms, including Rydberg-atom and cavity-QED platforms.

description: The gains to developing countries from agricultural reform in developed countries is found to benefit most, even the net food importers, although the gains vary depending on a country’s trade pattern. This results because the agricultural policy of a small number of developed countries cause the major distortions in world markets, and developing countries whose major share of agricultural trade is with the E.U. are impacted quite differently than those trading with the U.S. Even though Japan and Korea maintain high trade barriers, these barriers are found to have small effects on developing countries. The long-run benefits of reform are found to greatly exceed the short-run gains.

description: Most of the dark matter (DM) search over the last few decades has focused on WIMPs, but the viable parameter space is quickly shrinking. Asymmetric Dark Matter (ADM) is a WIMP-like DM candidate with slightly smaller masses and no present day annihilation, meaning that stars can capture and build up large quantities. The captured ADM can transport energy through a significant volume of the star. We investigate the effects of spin-dependent ADM energy transport on stellar structure and evolution in stars with $0.9 \leq M_{\star}/\mathrm{M}_{\odot} \leq 5.0$ in varying DM environments. We wrote a MESA module that calculates the capture of DM and the subsequent energy transport within the star. We fix the DM mass to 5 GeV and the cross section to $10^{-37} \mathrm{cm{^2}}$, and study varying environments by scaling the DM capture rate. For stars with radiative cores ($M_{\star} \lesssim 1.3\ \mathrm{M}_{\odot}$), the presence of ADM flattens the temperature and burning profiles in the core and increases MS ($X_c > 10^{-3}$) lifetimes by up to $\sim 20\%$. We find that strict requirements on energy conservation are crucial to the simulation of ADM's effects on these stars. In higher-mass stars, ADM energy transport shuts off core convection, limiting available fuel and shortening MS lifetimes by up to $\sim 40\%$. This may translate to changes in the luminosity and effective temperature of the MS turnoff in population isochrones. The tip of the red giant branch may occur at lower luminosities. The effects are largest in DM environments with high densities and/or low velocity dispersions, making dwarf and early forming galaxies most likely to display the effects.
