description: In this paper, we study a variant of the dynamic ridesharing problem with a specific focus on peak hours: Given a set of drivers and rider requests, we aim to match drivers to each rider request by achieving two objectives: maximizing the served rate and minimizing the total additional distance, subject to a series of spatio-temporal constraints. Our problem can be distinguished from existing work in three aspects: (1) Previous work did not fully explore the impact of peak travel periods where the number of rider requests is much greater than the number of available drivers. (2) Existing solutions usually rely on single objective optimization techniques, such as minimizing the total travel cost. (3) When evaluating the overall system performance, the runtime spent on updating drivers' trip schedules as per incoming rider requests should be incorporated, while it is excluded by most existing solutions. We propose an index structure together with a set of pruning rules and an efficient algorithm to include new riders into drivers' existing trip schedule. To answer new rider requests effectively, we propose two algorithms that match drivers with rider requests. Finally, we perform extensive experiments on a large-scale test collection to validate the proposed methods.

description: The range of fermented milk products is quite diverse on the world market, but bifidogenic enriched dairy products are not common. Fermented milk products probiotics to restore the beneficial intestinal microflora in combination with probiotics and natural ingredients of plant origin is of great interest. Industrial processing of functional ingredients allows to apply the principles of waste-free technologies, increasing food resources, thereby increasing the economic efficiency of the technology and eliminates environmental pollution. The implementation of research results in the production will create a competitive acidophilic product that combines harmonious organoleptic and functional properties, intended for use in both therapeutic and prophylactic purposes, and for mass use. The use of bee pollen for the production of acidophilic products will give them bifidogenic and immunostimulatory properties that improve human health. The dose of bee pollen (1.0%) and the technological stage of its introduction in the production of acidophilic product by thermostatic method have been recommended, i.e. pre-dissolution in hot milk for 5 minutes and cooled to fermentation temperature, application to the prepared milk base during fermentation before bottling. The effectiveness of acid formation in the fermentation of acidophilic product with bee pollen have been investigated. When adding the additive, the acid formation process is more efficient reducing the fermentation time by 1.5 hours
Transition probabilities and transition rates in discrete phase space

description: The evolution of the discrete Wigner function is formally similar to a probabilistic process, but the transition probabilities, like the discrete Wigner function itself, can be negative. We investigate these transition probabilities, as well as the transition rates for a continuous process, aiming particularly to give simple criteria for deciding when a set of such quantities corresponds to a legitimate quantum process. We also show how the transition rates for any Hamiltonian evolution can be worked out by expanding the Hamiltonian as a linear combination of displacement operators in the discrete phase space.

Why do warm Neptunes present nonzero eccentricity?

description: Most Neptune-mass planets in close-in orbits (orbital periods less than a few days) present nonzero eccentricity, typically around 0.15. This is somehow unexpected, as these planets undergo strong tidal dissipation that should circularize their orbits in a time-scale shorter than the age of the system. In this paper we discuss some mechanisms that can oppose to bodily tides, namely, thermal atmospheric tides, evaporation of the atmosphere, and excitation from a distant companion. In the first two cases, the eccentricity can increase consistently, while in the last one, the eccentricity can only be excited for a limited amount of time (that may nevertheless exceed the age of the system). We show the limitations of these different mechanisms and how some of them could, depending on specific properties of the observed planetary systems, account for their presently observed eccentricities.

description: The particle-antiparticle asymmetries of $Λ$ production in 250 GeV/c $π^{\pm}$, $K^{\pm}$, and $p$ --nucleon collisions are studied with two model parametrizations of quark to $Λ$ fragmentation functions. It is shown that the available data can be qualitatively explained by the calculated results in both the quark-diquark model and a pQCD based analysis of fragmentation functions. The differences in the two model predictions are significant for $K^{\pm}$ beams, and high precision measurements of the asymmetries with detailed $x_F$ and $P_T$ information can discriminate between different predictions.

description: We prove that with a $(2+1)$-dimensional Toda type system are associated algebraic skeletons which are (compatible assemblings) of particle-like Lie algebras of dyons and triadons type. We obtain trix-coaxial and dyx-coaxial Lie algebra structures for the system from algebraic skeletons of some particular choice for compatible associated absolute parallelisms. In particular, by a first choice of the absolute parallelism, we associate with the $(2+1)$-dimensional Toda type system a trix-coaxial Lie algebra structure made of two (compatible) base triadons constituting a $2$-catena. Furthermore, by a second choice of the absolute parallelism, we associate a dyx-coaxial Lie algebra structure made of two (compatible) base dyons, as well as particle-like Lie algebra structures made of single $3$-dyons. Some explicit examples of applications such as conservation laws related to special solutions, and an inverse spectral problem are worked out.

description: This introductory essay for the journal Symposium presents an overview of issues related to ‘Q-Squared in Policy: the use of qualitative and quantitative methods of poverty analysis in decision-making’. We focus on issues raised on the supply side of data use, relating, inter alia to the informational content and policy usefulness of different types of data and analysis. These issues are grouped under the headings of: outcomes vs. processes, unpacking processes and thick and thin. We begin however, with a brief discussion of one aspect of the demand side, namely the politics of data use, given its centrality to the issues at hand.
Some improvements on the one-step inverse isogeometric analysis by proposing a multi-step inverse isogeometric methodology in sheet metal stamping processes

description: The isogeometric methodology has been successfully implemented in one-step inverse analysis of sheet metal stamping processes. However, these models are not capable of analyzing forming processes that require severe deformation and several forming stages. This paper presents a multi-step inverse isogeometric methodology to enhance the precision of one-step models in predictions of the initial blank, strain distributions, and drawability of the formed parts. This methodology deals with the minimization of potential energy, deformation theory of plasticity, and considering membrane elements. The presented methodology utilizes the NURBS basis functions to create the final, middle, and blank geometries and also to analyze sheet metal deformation. The characteristics of the applied formulations make it possible to simultaneously observe the effects of changing part parameters on its formability. One advantage of this approach is that the linear system of governing equations is solved without concerning about the convergence. Besides, the presented methodology can successfully generate the middle geometry and to restrict the movements of physical nodes along the middle surface, by presenting a new NURBS-based mapping and sliding constraint technique. The performance of the presented model is experimentally and numerically evaluated under two classical problems, including the forming of a rectangular box and a two-step drawing of a circular cup. Results comparisons indicate the credibility of the presented model in prediction of forming parameters at a low computation time.

description: In most experiments on the Casimir force the comparison between measurement data and theory was done using the concept of the root-mean-square deviation, a procedure that has been criticized in literature. Here we propose a special statistical analysis which should be performed separately for the experimental data and for the results of the theoretical computations. In so doing, the random, systematic, and total experimental errors are found as functions of separation, taking into account the distribution laws for each error at 95% confidence. Independently, all theoretical errors are combined to obtain the total theoretical error at the same confidence. Finally, the confidence interval for the differences between theoretical and experimental values is obtained as a function of separation. This rigorous approach is applied to two recent experiments on the Casimir effect.

description: This paper raises a number of issues in thinking about and addressing the intergenerational transmission of disadvantage. Starting with choice subject to constraints by parents as determining outcomes for children, the paper identifies sequences of interventions to relieve “binding constraints” in the expansion of education. But the fact that parents choose for children is shown to raise a number of questions on normative aspects of inequality measurement. The main conclusions are as follows: (i) A key analytical task is to identify whether education is supply constrained or demand constrained; (ii) The cost-benefit analysis of identifying the “most binding constraint” requires the estimation of an education quality production function; (iii) The recent focus on “quality as opposed to quantity” in education is not self-evidently pro-poor; (iv) The intergenerational links inherent in education between parental choice and children’s outcomes, raise serious conceptual and empirical questions on attempts to separate out inequality of opportunity from inequality of outcomes.

The Harish-Chandra-Howe local expansion expresses this character near a semisimple element as a linear combination of Fourier transforms of nilpotent orbital integrals. Under mild hypotheses, we describe an explicit region on which the local character expansion is valid. We assume neither that the group is connected nor that the underlying field has characteristic zero.

Minimal disturbance measurement for coherent states is non-Gaussian

Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In standard coherent state teleportation with shared two-mode squeezed vacuum (TMSV) state there is a trade-off between the teleportation fidelity and the fidelity of estimation of the teleported state from results of the Bell measurement. Within the class of Gaussian operations this trade-off is optimal, i.e. there is not a Gaussian operation which would give for a given output fidelity a larger estimation fidelity. We show that this trade-off can be improved by up to 2.77% if we use a suitable non-Gaussian operation. This operation can be implemented by the standard teleportation protocol in which the shared TMSV state is replaced with a suitable non-Gaussian entangled state. We also demonstrate that this operation can be used to enhance the transmission fidelity of a certain noisy channel.

Modified pure spinors and mirror symmetry

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It has been argued recently that mirror symmetry exchanges two pure spinors characterizing a generic manifold with SU(3)-structure. We show how pure spinors are modified in the presence of topological D-branes, so that they are still exchanged by mirror symmetry. This exchange emerges from the fact that the modified pure spinors come out as moment maps for the symmetries of A and B-models. The modification by the gauge field is argued to ensure the inclusion into the mirror exchange of the A-model non-Lagrangian branes endowed with a non-flat connection. Treating the connection as a distribution on an ambient six-manifold, assumed to be T^3-fibered, the proposed mirror formula is established by fiberwise T-duality.

D’Groove - a novel digital haptic turntable for music control
Creators: name: Beamish, Timothy Mark Edward
Publisher: name: University of British Columbia
Year: 2009

description: Disc Jockeys (DJs) use creative methods to play pre-recorded music at social events. Their tools, however, are relatively archaic and there is a desire for advanced equipment with the capacity to increase the level of creativity involved in a DJ's performance. The overall goal of the work described here is to create an advanced DJ system that promotes creativity, allows control of digital music and improves upon previous DJ tools. This thesis begins with an analysis of DJs using conventional tools and procedures, followed by a discussion of previous attempts to upgrade DJ technology. These findings led to our first prototype controller, D'Groove, a novel digital DJ system with haptic, visual and auditory interaction. Experienced DJs from a variety of specializations tested our prototype, resulting in useful feedback and the discovery of some exciting new expressive uses that we had not intended. They discussed the technological needs and wants of the next generation of DJs, providing input to our user-centered design strategy. While D'Groove is for DJs, the experiences of our experts provide insight to the general problem of interacting with digital media streams. The main contributions of this thesis are a description of the processes and tools used by DJs; the design and evaluation of D'Groove, an advanced user-oriented haptic DJ system for manipulating digital music; and a summary of guidelines for manipulating digital audio in general.

description: Houses in Sanskrit are referred to as ‘bhava’ meaning a mode of being, essence or feeling, and are thus, in Vedic Astrology, a changing twelvefold division of the zodiac circle, which depend upon the position of the earth in its daily rotation relative to the heaven. As the earth rotates during the course of the day, the whole zodiac gradually rises in the East and sets in the West. The tenth house is the zodiac sign which is exactly on the top (the north direction) at the time of birth. Significance of the Seventh house and the impacts created by the planetary position in the horoscope for a person’s marriage life is analysed in this article.

description: Analysis of data from an Affymetrix Latin Square spike-in experiment indicates that measured fluorescence intensities of features on an oligonucleotide microarray are related to spike-in RNA target concentrations via a hyperbolic response function, generally identified as a Langmuir adsorption isotherm. Furthermore the asymptotic signal at high spike-in concentrations is almost invariably lower for a mismatch feature than for its partner perfect match feature. We survey a number of theoretical adsorption models of hybridization at the microarray surface and find that in general they are unable to explain the differing saturation responses of perfect and mismatch features. On the other hand, we find that a simple and consistent explanation can be found in a model in which equilibrium hybridization followed by partial dissociation of duplexes during the post-hybridization washing phase.

The Life of Forms

Year: 2015

description: In the preliminary work for his Theses On the Concept of History, Walter Benjamin quotes a passage from Henri Focillon’s La vie des formes, using Focillon’s description of classical style for his own notion of the dialectical image. The Essay locates Benjamin’s surprising reception of Focillon in their common interest in a life of forms, not so much in the sense of aesthetic liveliness as defined by Kant (‘Beförderung der Lebendigkeit‘), but in its productiveness of other forms. Focillon’s idea of art history is based on the dynamis or potentiality of artistic shapes giving way to ever new figures and forms. This is not only a key to Benjamin’s concepts of Fortleben/Nachleben in the early Essay The Task of the Translator but also to the ‘dialectical image‘ outlined in the Arcades Project. Benjamin, this Essay argues, refers to Focillon’s life of forms to conceptualise disharmonious and sudden changes of form.

description: We present new astrometry of Pluto's three satellites from images taken of the Pluto system during 2002-3 with the High Resolution Camera (HRC) mode of the Advanced Camera for Surveys (ACS) instrument on the Hubble Space Telescope. The observations were designed to produce an albedo map of Pluto but they also contain images of Charon and the two recently discovered satellites, S/2005 P1 and S/2005 P2. Orbits fitted to all three satellites are nearly co-planar and, for Charon and P2, have eccentricities consistent with zero. The orbit of the outermost satellite, P1, has a significant eccentricity of 0.0052 +/- 0.0011. Orbital periods of P1, P2, and Charon are 38.2065 +/- 0.0014, 24.8562 +/- 00013, and 6.3872304 +/- 0.0000011 days, respectively. The total system mass based on Charon's orbit is 1.4570 +/- 0.0009 x 10^22 kg. We confirm previous results that orbital periods are close to the ratio of 6:4:1 (P1:P2:Charon) indicative of mean-motion resonances, but our results formally preclude precise integer period ratios. The orbits of P1 and P2, being about the barycenter rather than Pluto, enable us to measure the Charon/Pluto mass ratio as 0.1165 +/- 0.0055. This new mass ratio implies a density of 1.65 +/- 0.06 g cm^-3 for Charon (603.6 km radius) and 2.03 +/- 0.06 g cm^-3 for Pluto (1153 km radius) thus adding confirmation that Charon is significantly less dense than Pluto. Finally, by stacking all images, we can extract globally averaged photometry. P1 has a mean opposition magnitude of V=24.39 +/- 0.09 and color of (B-V) = 0.64 +/- 0.12. P2 has a mean opposition magnitude of V=24.55 +/- 0.10 and color of (B-V) = 0.91 +/- 0.15.

description: I consider the quantum electromagnetic field in a coaxial cylindrical waveguide, such that the outer cylindrical surface has a time-dependent radius. The field propagates parallel to the axis, inside the annular region between the two cylindrical surfaces. When the mechanical frequency and the thickness of the annular region are small enough, only Transverse Electromagnetic (TEM) photons may be generated by the dynamical Casimir effect. The photon emission rate is calculated in this regime, and compared with the case of parallel plates in the limit of very short distances between the two cylindrical surfaces. The proximity force approximation holds for the transition matrix elements in this limit, but the emission rate scales quadratically with the mechanical frequency, as opposed to the cubic dependence for parallel plates.

Clebsch Confinement and Instantons in Turbulence

Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We introduce a concept of Clebsch confinement related to unbroken gauge invariance and study Clebsch instantons: singular vorticity sheets with nontrivial helicity. This is realization of the "Instantons and intermittency" program we started back in the 90ties\cite{FKLM}. These singular solutions are involved in enhancing infinitesimal random forces at remote boundary leading to critical phenomena. In the Euler equation vorticity is concentrated along the random self-avoiding surface, with tangent components proportional to the delta function of normal distance. Viscosity in Navier-Stokes equation smears this delta function to the Gaussian with width $h \propto ν^{\nicefrac{3}{5}}$ at $ν\ra 0$ with fixed energy flow. These instantons dominate the enstrophy in dissipation as well as the PDF for velocity circulation $Γ_C$ around fixed loop $C$ in space. At large loops, the resulting symmetric exponential distribution perfectly fits the numerical simulations\cite{IBS20} including pre-exponential factor $1/\sqrt{|Γ|}$. At small loops, we advocate relation of resulting random self-avoiding surface theory with multi-fractal scaling laws observed in numerical simulations. These laws are explained as a result of fluctuating internal metric (Liouville field). The curve of anomalous dimensions $ζ(n)$ can be fitted at small $n$ to the parabola, coming from the Liouville theory with two parameters $α, Q$. At large $n$ the ratios of the subsequent moments in our theory grow linearly with the size of the loop, which corresponds to finite value of $ζ(\infty)$ in agreement with DNS.

description: Economic research has documented many economic affects of offspring gender on parental behavior. However, an open question exists as to whether offspring gender has any influence on parental investment decision making. Specifically, I investigate whether female offspring have an impact on investment decisions with respect to stock and bondholding. Using a panel data set, I find that for male respondents, having only female offspring increases the probability of stockholding by over 17%. In contrast, a relationship between stockholding and offspring gender was not at all present for female respondents.

Tests carried out to characterize the new system showed a higher system gain with a lower read-out noise electron level. Shorter read-out cycle times now allow to compensate tip-tilt fluctuations so that their error imposed on visibility measurements becomes comparable to, and even smaller than, that of higher-order aberrations.

description: The genesis of the Curie-Weiss magnetic response observed in most transition metals that are Fermi liquids at low temperatures has been an enigma for decades and has not yet been fully explained from microscopic principles. We show on the single-impurity Anderson model how the quantum dynamics of strong electron correlations leads to the Curie-Weiss magnetic susceptibility sufficiently above the Kondo temperature. Such behavior has not yet been demonstrated and can be observed only when the bare interaction is substantially screened (renormalized) and a balance between quantum and thermal fluctuations is kept. We set quantitative criteria for the existence of the Curie-Weiss law.

description: We discuss the effects of interlayer hopping and the resulting $k_z$-dispersion in the cuprates within the framework of the one-band tight binding (TB) model Hamiltonian. Specific forms of the dispersion relations in terms of the in-plane hopping parameters $t$, $t'$, $t''$ and $t'''$ and the effective interlayer hopping $t_z$ in La$_{2-x}$Sr$_x$CuO$_4$ (LSCO) and Nd$_{2-x}$Ce$_x$CuO$_4$ (NCCO) and the added intracell hopping $t_{bi}$ between the CuO$_2$ bilayers in Bi$_2$Sr$_2$CaCu$_2$O$_{8}$ (Bi2212) are presented. The values of the `bare' parameters are obtained via fits with the first principles LDA-based band structures in LSCO, NCCO and Bi2212. The corresponding `dressed' parameter sets which account for correlation effects beyond the LDA are derived by fitting experimental FS maps and dispersions near the Fermi energy in optimally doped and overdoped systems. The interlayer couplings $t_z$ and $t_{bi}$ are found generally to be a substantial fraction of the in-plane hopping $t$, although the value of $t_z$ in NCCO is anomalously small, reflecting absence of apical O atoms in the crystal structure. Our results provide some insight into the issues of the determination of doping from experimental FS maps in Bi2212, the role of intercell coupling in c-axis transport, and the possible correlations between the doping dependencies of the binding energies of the Van Hove singularities (VHSs) and various prominent features observed in the angle-resolved photoemission (ARPES) and tunneling spectra of the cuprates.

description: We employ a topological approach to investigate the nature of quasi-stationary states of the Mean Field XY Hamiltonian model that arise when the system is initially prepared in a fully magnetized configuration. By means of numerical simulations and analytical considerations, we show that, along the quasi-stationary trajectories, the system evolves in a manifold of critical points of the potential energy function. Although these critical points are maxima, the large number of directions with marginal stability may be responsible for the slow relaxation dynamics and the trapping of the system in such trajectories.

We show that there is a uniruled algebraic variety X such that the connected sum M#N of M and N is diffeomorphic to a connected component of the set of real points X(R) of X. In particular, any finite connected sum of lens spaces is diffeomorphic to a real component of a uniruled algebraic variety.

description: To investigate the non-perturbative, electric sector of a deconfined gauge theory at nonzero temperature, we consider a SU(2) matrix model. We compute beta-functions to one loop order for the simplest extension of the O(4) nonlinear sigma model, which involves three coupling constants. Computing in the ultraviolet limit in 2 + epsilon dimensions, we find that at least one coupling is not asymptotically free.

description: We show that the problem of stabilization of extra dimensions in Kaluza-Klein type cosmology may be solved in a theory of gravity involving high-order curvature invariants. The method suggested (employing a slow-change approximation) can work with rather a general form of the gravitational action. As examples, we consider pure gravity with Lagrangians quadratic and cubic in the scalar curvature and some more complex ones in a simple Kaluza-Klein framework. After a transition to the 4D Einstein conformal frame, this results in effective scalar field theories with certain effective potentials, which in many cases possess positive minima providing stable small-size extra dimensions. Estimates made in the original (Jordan) conformal frame show that the problem of a small value of the cosmological constant in the present Universe is softened in this framework but is not solved completely.}

BIODEGRADABLE MATERIALS USED IN ORTHOPAEDICS

Subjects: biodegradable materials

description: As technology advances, the number of inventions and discoveries also increases in order to make life and work easier. In the field of orthopaedics, for internal fixation of bone fractures, the presence of implants is required for the time needed for fracture healing and then they should be removed. Thus to solve this problem the mechanical non-degradable implants may be replaced by biodegradable ones. Biodegradable materials are used now in the form of screws, rods, sutures, staples etc. According to the site of a fracture and patient’s condition, the usage of bioabsorbable implants differs, but nowadays biodegradable screws, pins and plates are used for fixation of various fracture patterns in different parts of the body. Biodegradable implants have specific demands and limitations. They should be biocompatible, have good mechanical properties and have non toxic degradation products. Polyglycolic acid (PGA), polylactic acid (PLA) are the most researched biocompatible and biodegradable polymers. Their linear copolymer poly lactic-co-glycolic acid (PLGA) that can be prepared at different ratios between its constituent monomers lactic and glycolic acid allows to correct the physical and chemical properties of the implants. In this paper, various applications and features of different biodegradable or bioabsorbable materials used in orthopedics for fracture fixation were analysed.
L’origine, la ferita

description: Shutter Island (Paramount Pictures 2010) is a much-criticized and highly debated film. Scorsese, in fact, has been accused of distorting the facts and altering his historical sources. The depictions we see of the Holocaust are false, not based on visual documents, a mix of incompatible evidences and iconographies, an amalgam of irreconcilable informations and representations. The director has created a visual style and a sound design that vacillate between thriller and horror, drama and fantasy, while betraying the medial transparency of the reconstruction and the ethical responsibility of interpretation. The viewer sees and believes in the images of the concentration camp of Dachau which are, in reality, dialectical imaginings of another scene: in these images, constructed according to the clinical and critical vision of Scorsese as cinephile, the past and the repressed return in the present. In our present too. On the one hand, in fact, the viewer participates empathically in the mental images relived and suffered by the protagonist in his post-traumatic hallucinations; on the other hand, the viewer is prompted to recall the pictures quoted or paraphrased from the archives of the imagery of cinema and of the photojournalism of war–in which Pontecorvo, Resnais, Fuller, George Stevens and John Huston live side by side with the RKO horror films of Jacques Tourneur and Mark Robson. For Scorsese, the images of the violence of war and of the horror of extermination cannot be linked to an origin or past that have definitively been concluded. They are more than recorded pictures or concrete evidences: they are clues and symptoms. They come from a conflictual and endless descent of which cinema is the living and ambiguous memory; they are the open wounds of an original struggle between human and inhuman and of man–they still survive, here and now.
