A new approach to parton recombination in a QCD evolution equation
Creators: name: Zhu, Wei
Publisher: name: arXiv
Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Parton recombination is reconsidered in perturbation theory without using the AGK cutting rules in the leading order of the recombination. We use time-ordered perturbation theory to sum the cut diagrams, which are neglected in the GLR evolution equation. We present a set of new evolution equations including parton recombination.

description: Motivated by recent developments in string theory, we study the structure of boundary conditions in arbitrary conformal field theories. A boundary condition is specified by two types of data: first, a consistent collection of reflection coefficients for bulk fields on the disk; and second, a choice of an automorphism $ω$ of the fusion rules that preserves conformal weights. Non-trivial automorphisms $ω$ correspond to D-brane configurations for arbitrary conformal field theories. The choice of the fusion rule automorphism $ω$ amounts to fixing the dimension and certain global topological features of the D-brane world volume and the background gauge field on it. We present evidence that for fixed choice of $ω$ the boundary conditions are classified as the irreducible representations of some commutative associative algebra, a generalization of the fusion rule algebra. Each of these irreducible representations corresponds to a choice of the moduli for the world volume of the D-brane and the moduli of the flat connection on it.

description: This paper presents a legal-economic analysis of the Appellate Body's decision in EU-Biodiesel (Argentina) that the WTO's Anti-Dumping Agreement (ADA) does not permit countries to take into account government-created price distortions of major inputs when calculating antidumping duties. In this case, the EU made adjustments to the price of biodiesel's principal input - soybeans - in determining the cost of production of biodiesel in Argentina. The adjustment was made based on the uncontested finding that the price of soybeans in Argentina was distorted by the existence of an export tax scheme that resulted in artificially low soybean prices. The Appellate Body found that the EU was not permitted to take tax policy-induced price distortions into account in calculating dumping margins. We analyze the economic rationale for Argentina's export tax system, distortions in biodiesel markets in Argentina and the EU, and the remaining trade policy options for addressing distorted international prices. We also assess whether existing subsidies disciplines would be more effective in addressing this problem and conclude that they would not.

description: In this episode the usual suspects, Mills, Stephen, Amanda, Dan and Tom gathered for yet another lively discussion. The episode began with a discussion on the trend toward opening data as several big players, the Getty, Twitter, Microsoft and the Public Library of Science took steps toward greater accessibility of their resources. The hosts also highlighted the subject of virtual conference attendance, looking at the “dopplebot” conference attendance model. From big changes to a historical look back, the group switched gears to discuss a Pew Report that looks back at 25 years of internet use, broad discussion of changes and how the internet has become an indispensable facet of our lives. Nothing demonstrates that more than the next topic of discussion, the $19 billion dollar purchase of WhatsApp. They were joined by Sharon Leon, director of Public Projects at CHNM for an announcement about two upcoming summer institutes at CHNM for Art Historians and American Historians.
TOMs and Telescope Networks for Time-Domain and Transient Targeting
Creators: name: Lister, Tim
Publisher: name: Zenodo
Year: 2024

description: The ability to synthesize discovery data from multiple sources, and respond with complementary follow-up observations in real-time, is critical to many science goals in Multi-Messenger and Time-Domain Astrophysics. In an era of large increases in the number of targets both overall and for a particular science area of interest, the need for Target and Observation Manager (TOM) systems to coordinate follow-up and networks of telescopes such as AEON (Astronomical Event Observatory Network) that can rapidly respond to follow and characterize new discoveries becomes vital.

 

The TOM Toolkit provides easy-to-use software tools to enable observers to manage discoveries and data in real-time, filter and identify their targets of interest and obtain the observations necessary for characterization. We provide an overview of the TOM Toolkit, including recent upgrades to the TOM Toolkit to support detections from Gravitational Wave and Neutrino detectors, observations on the Swift satellite as well as support for discovery follow-up in the LSST era. With the large volume of targets, efficient use of a finite set of telescope resources for follow-up is essential. AEON has developed tools to enable observatories to be more responsive to time-domain observations, while retaining complete control over their operations and time allocation. These applications include an online portal to submit observation requests and software to help operators to manage and schedule the requested observations.

description: We study by computer simulation the nucleation of a supersaturated Lennard-Jones vapor into the liquid phase. The large free energy barriers to transition make the time scale of this process impossible to study by ordinary molecular dynamics simulations.Therefore we use a recently developed enhanced sampling method [Valsson and Parrinello, Phys. Rev. Lett. 113, 090601 (2014)] based on the variational determination of a bias potential. We differ from previous applications of this method in that the bias is constructed on the basis of the physical model provided by the classical theory of nucleation. We examine the technical problems associated with this approach. Our results are very satisfactory and will pave the way for calculating the nucleation rates in many systems.

description: Neutrino oscillation scenarios predict correlations, and zones of avoidance, among measurable quantities such as spectral energy distortions, total fluxes, time dependences, and flavor content. The comparison of observed and predicted correlations will enhance the diagnostic power of solar neutrino experiments. A general test of all presently-allowed (two neutrino) oscillation solutions is that future measurements must yield values outside the predicted zones of avoidance. To illustrate the discriminatory power of the simultaneous analysis of multiple observables, we map currently allowed regions of neutrino masses and mixing angles onto planes of quantities measurable with the Sudbury Neutrino Observatory (SNO). We calculate the correlations that are predicted by vacuum and MSW (active and sterile) neutrino oscillation solutions that are globally consistent with all available neutrino data. We derive approximate analytic expressions for the dependence of individual observables and specific correlations upon neutrino oscillations parameters. We also discuss the prospects for identifying the correct oscillation solution using multiple SNO observables.

description: Last week as I drove the Greenway from Leesburg, heading on to Dulles Airport and to Washington, it occurred to me that the driving experience can actually be a pleasure. It’s true that driving is often a frustrating experience due to traffic congestion. In addition it’s become a more costly experience as the price of gas has been hijacked by foreign suppliers. And, yes, aggressive driving and increasing instances of road rage make the experience increasingly hazardous. But gliding leisurely along the Greenway, admiring the stretching greenswards on every hand, I marveled at the contrast in driving experience I was about to encounter on the Dulles Toll Road. A former Reston resident and architect of considerable distinction, Wayne L. Hughes, has explained to me that there’s more to this contrast than the view of rural nature versus exploding urbanscapes and low versus high traffic counts. He is leading a campaign to force the Virginia Department of Transportation (VDOT) to replace its signage system on the Toll Road which, he says, “takes the concept of confusion to a new level.”

description: In this work, issues in phase retrieval in the coherent diffractive imaging (CDI) technique, from discussion on parameters for setting up a CDI experiment to evaluation of the goodness of the final reconstruction, are discussed. The distribution of objects under study by CDI often cannot be cross-validated by another imaging technique. It is therefore important to make sure that the developed CDI procedure delivers an artifact-free object reconstruction. Critical issues that can lead to artifacts are presented and recipes on how to avoid them are provided.
Reorganise, Replace or Expand? The role of the supply-chain in first-time exporting

description: Modern trade theory models exporting as paying a fixed-cost in order to access a larger market. This simplification ignores an essential component of the export process: how does the decision to export cause firms to alter their supply-chains? In this paper I demonstrate that first-time exporting not only leads to growth in exporter output and productivity, but also influences the supply-chain in three main ways depending on the exporters size. First, new exporters replace unproductive suppliers with more productive domestic suppliers. Second, new exporters replace existing suppliers with imported alternatives. Third, exporting leads to pecuniary spillovers passed onto domestic suppliers, observed in higher revenue productivity. I use a unique, high-frequency Government of Uganda value-added tax administrative dataset motivated by a simple matching model to provide the first evidence on these effects. The model is identified by exploiting a natural experiment of a reduction in international transportation costs.
Targeting Interventions in Networks

Year: 2017

description: Individuals interact strategically with their network neighbours, as in effort investment with spillovers among peers, or production decisions among firms connected by a supply chain. A planner can shape their incentives in pursuit of some goal-for instance, maximizing utilitarian welfare or minimizing the volatility of aggregate activity. We offer an approach to solving such intervention problems that exploits the singular value decomposition of network interaction matrices. The approach works by (i) describing the game in new coordinates given by the singular value decomposition of the network on which the game is played; and (ii) using that to deduce which components, and hence which individuals, a given type of intervention will focus on. Across a variety of intervention problems, simple orderings of the principal components characterize the planner's priorities.

Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Many qualitatively new features of WZNW models associated to noncompact cosets are due to zero modes with continuous spectrum. Insight may be gained by reducing the theory to its zero-mode sector, the mini-superspace limit. This will be discussed in some detail for the example of SL(2,C)/SU(2)-WZNW model. The mini-superspace limit of this model can be formulated as baby-CFT. Spectrum, structure constants and fusion rules as well as factorization of four point functions are obtained from the harmonic analysis on SL(2,C)/SU(2). The issues of operator-state correspondence or the appearance of non-normalizable intermediate states in correlation functions can be discussed transparently in this context.

description: Communications play a vital role in the response to disasters and crises. However, existing communications infrastructure is often impaired, destroyed or overwhelmed during such events. This leads to the use of substitute communications solutions including analog two-way radio or unsecured internet access. Often provided by unknown third parties, these solutions may have less sophisticated security characteristics than is desirable. While substitute communications are often invaluable, care is required to minimize the risk to NGOs and individuals stemming from the use of communications channels with reduced or unknown security properties. This is particularly true if private information is involved, including the location and disposition of individuals and first responders. In this work we enumerate the principal risks and challenges that may arise, and provide practical guidelines for mitigating them during crises. We take plausible threats from contemporary disaster and crisis events into account and discuss the security and privacy features of state-of-the-art communications mechanisms.

description: This paper outlines a motivation for associating IED events (and other significant physical and human geographic features) with the road network, describes the use of methods known as linear referencing in order to do so, and presents an example of how linear referencing of several types of events can occur. This is followed by a description of several measures of network density of events, and a demonstration of how linearly referenced events can be combined to analyze spatial coincidence of different event types. This is followed by suggestions for future research including the development of network based spatial statistics, optimization of network services based on the linearly referenced events, and geographic information system tool development to integrate these methods.

description: Atomic magnetometry is one of the most sensitive ways to measure magnetic fields. We present a method for converting a naturally scalar atomic magnetometer into a vector magnetometer by exploiting the polarization dependence of hyperfine transitions in rubidium atoms. First, we fully determine the polarization ellipse of an applied microwave field using a self-calibrating method, i.e. a method in which the light-atom interaction provides everything required to know the field in an orthogonal laboratory frame. We then measure the direction of an applied static field using the polarization ellipse as a three-dimensional reference defined by Maxwell's equations. Although demonstrated with trapped atoms, this technique could be applied to atomic vapors, or a variety of atom-like systems.

On the Chiral Quark Soliton Model with Pauli-Villars Regularization

description: The Pauli-Villars regularization scheme is often used for evaluating parton distributions within the framework of the chiral quark soliton model with inclusion of the vacuum polarization effects. Its simplest version with a single subtraction term should however be taken with some caution, since it does not fully get rid of divergences contained in scalar and psuedoscalar quark densities appearing in the soliton equation of motion. To remedy this shortcoming, we propose here its natural extention, i.e. the Pauli-Villars regularization scheme with multi-subtraction terms. We also carry out a comparative analysis of the Pauli-Villars regularization scheme and more popular proper-time one. It turns out that some isovector observables like the isovector magnetic moment of the nucleon is rather sensitive to the choice of the regularization scheme. In the process of tracing the origin of this sensitivity, a noticeable difference of the two regularization scheme is revealed.

description: In response to financial turmoil that began in 2007 and the effective lower bound for short-term interest rates that was reached in late-2008, the Federal Reserve adopted a raft of 'unconventional' monetary policies, notably: forward guidance and large-scale asset purchases. These policies transmit to the real economy, inter alia, via an interest rate channel, with two sub-channels: signalling and portfolio rebalancing. I apply the OIS-augmented decomposition of interest rates from Lloyd (2017a) to identify these two sub-channels. I demonstrate that US unconventional monetary policy announcements between November 2008 and April 2013 did exert significant signalling and portfolio balance effects on financial markets, reducing longer-term interest rates. Signalling effects were particularly powerful at horizons in excess of two years. As a result of these declines, unconventional monetary policy aided real economic outcomes. I show that the signalling channel exerted a more powerful influence on US industrial production and consumer prices than portfolio rebalancing. In terms of long-term bond yield and industrial production effects, the signalling channel is associated with around two-thirds to three-quarters of the total effects attributed to the two channels.

description: Smartphone-based communication networks form a basis for services in emergency response scenarios, where communication infrastructure is impaired or overloaded. Still, their design and evaluation are largely based on simulations that rely on generic mobility models and weak assumptions regarding user behavior. For a realistic assessment, scenario-specific models are essential. To this end, we conducted a large-scale field test of a set of emergency services that relied solely on ad hoc communication. Over the course of one day, we gathered data from smartphones distributed to 125 participants in a scripted disaster event. In this paper, we present the scenario, measurement methodology, and a first analysis of the data. Our work provides the first trace combining user interaction, mobility, and additional sensor readings of a large-scale emergency response scenario, facilitating future research.

We develop a scheme for modal reconstruction from interferometric measurements that accounts for the ensuing clipping effects. Clipping-cognizant reconstruction is shown to yield significant performance gains over traditional schemes that overlook such effects that do arise in practice. Our work can inspire further research on reconstruction schemes and algorithms that account for practical hardware limitations in a variety of contexts.

description: Objective: Sensory hypersensitivity is common after acquired brain injury. Since appropriate diagnostic tools are lacking, these complaints are overlooked by clinicians and available literature is limited to light and noise hypersensitivity after concussion. This study aimed to investigate the prevalence of sensory hypersensitivity in other modalities and after other types of brain injury. Method: We developed the Multi-Modal Evaluation of Sensory Sensitivity (MESSY), a patient-friendly questionnaire that assesses sensory sensitivity across multiple sensory modalities. 818 neurotypical adults (mean age = 49; 244 male) and 341 chronic acquired brain injury patients (including stroke, traumatic brain injury, and brain tumour patients) (mean age = 56; 126 male) completed the MESSY online. Results: The MESSY had a high validity and reliability in neurotypical adults. Post-injury sensory hypersensitivity (examined using open-ended questions) was reported by 76% of the stroke patients, 89% of the traumatic brain injury patients, and 82% of the brain tumour patients. These complaints occurred across all modalities with multisensory, visual, and auditory hypersensitivity being the most prevalent. Patients with post-injury sensory hypersensitivity reported a higher sensory sensitivity severity on the multiple-choice items of the MESSY as compared to neurotypical adults and acquired brain injury patients without post-injury sensory hypersensitivity (across all sensory modalities) (effect sizes (partial eta squared) ranged from .06 to .22). Conclusions: These results show that sensory hypersensitivity is prevalent after different types of acquired brain injury as well as across several sensory modalities. The MESSY can improve recognition of these symptoms and facilitate further research.

description: Objective: Older adults often spontaneously engage in compensatory strategies (CS) to support everyday task completion, but factors that influence success of chosen CS remain unclear. This study examines whether real-world prospective memory (PM) task completion is better predicted by CS count or a CS quality rating. Method: Seventy mid-life and older adult participants were presented four novel, real-world PM tasks via remote assessment and encouraged to use their typical CS. The examiner captured detailed information about planned CS at task presentation (T1) and utilized CS at follow-up testing (T2). From this information, count (CS Count; quantity of CS) and quality (CS Quality; rating of CS thoroughness and utility) scores were coded separately for the planned and utilized CS. PM task performance accuracy was also coded (PM Accuracy). Results: Hierarchical regressions revealed planned CS Count and Quality did not predict PM Accuracy. In contrast, the utilized CS Quality predicted a significant amount of PM Accuracy variance over and above CS Count, global cognition, and age (R2 = .47, ΔR2 = .24, ΔF = 29.36, p < .001, f2 = .45). Furthermore, utilized CS Quality accounted for a similar amount of variance in PM Accuracy when utilized CS Count was removed from the model. Conclusions: This study’s CS coding system can capture and quantify the quality of strategies, which uniquely predicts real-world PM performance. This coding system may provide researchers with a nuanced CS measure and lead to improved CS interventions designed to support everyday PM performance, such as targeted CS trainings.

description: A wide class of models with On-the-Job Search (OJS) predicts that workers gradually select into better-paying jobs. We develop a simple methodology to test predictions implied by OJS using two sources of identification: (i) time-variation in job-finding rates and (ii) the time since the last lay-off. Conditional on the termination date of the job, job duration should be distributed uniformly. This methodology is applied to the NLSY 79. We find remarkably strong support for all implications. The standard deviation of the wage offer distribution is about 15%. OJS accounts for 30% of the experience profile, 9% of total wage dispersion and an average wage loss of 11% following a lay-off.

We theorize that the Big Five personality traits exert a causal effect on the stable part of an individual's party preference and provide evidence from a large nationally representative English panel dataset in support of this theory. We find that supporters of the major parties (Labour, the Conservatives and the Liberal Democrats) have substantively different personality traits. Moreover, we show that those not identifying with any party, who are close to holding the majority, are similar to those identifying with the Conservatives. We show that these results are robust to controlling for cognitive skills and parental party preferences, and to estimation on a subsample of siblings. The relationship between personality traits and party identification is stable across birth cohorts.

description: Russian officials and commentators frequently complain that Washington applies double standards regarding its own behavior and Moscow's. America, these Russians claim, calls upon Moscow not to do things that Washington permits itself to do. Moscow's vitriolic opposition to the American proposal to deploy ballistic missile defense facilities in Poland and the Czech Republic, though, suggests that it is actually these Russian officials who are guilty of applying double standards.

description: Accessing fluid infiltration in nanogranular coatings is an outstanding challenge, of relevance for applications ranging from nanomedicine to catalysis. A sensing platform, allowing to quantify the amount of fluid infiltrated in a nanogranular ultrathin coating, with thickness in the 10 to 40 nm range, is here proposed and theoretically investigated by multiscale modelling. The scheme relies on impulsive photoacoustic excitation of hypersonic mechanical breathing modes in engineered gas-phase synthesised nanogranular metallic ultathin films and time-resolved acousto-optical read-out of the breathing modes frequency shift upon liquid infiltration. A superior sensitivity, exceeding 26x103 cm^2/g, is predicted upon equivalent areal mass loading of a few ng/mm^2. The capability of the present scheme to discriminate among different infiltration patterns is discussed. The platform is an ideal tool to investigate nano fluidics in granular materials and naturally serves as a distributed nanogetter coating, integrating fluid sensing capabilities. The proposed scheme is readily extendable to other nanoscale and mesoscale porous materials.

description: This thesis describes the design and implementation of a web-based tool – MIAMI (miRNA and mRNA integrated analysis) – that enables integrative analysis of target predictions, miRNA and gene expression data. MIAMI is divided into two parts: the query section and the analysis section. The query section allows the user to retrieve and browse updated miRNA-mRNA pairs predicted using a number of different computational algorithms such as PITA, miRanda and Target Scan as well as Boolean combinations of these algorithms. The analysis section comprises a multi-step procedure for (i) performing various statistical analyses of mRNA and miRNA expression data; (ii) visualization of networks of the highest confidence miRNA and mRNA interactions and; (iii) retrieval of gene, miRNA and disease-specific information available in several public databases via scientific literature text-mining.
Temperature Runaway in a Pulsed Dielectric Barrier Discharge Reactor

description: This paper reports on experimental measurements of the gas temperature in a dielectric barrier discharge reactor powered by a high voltage pulsed signal. It is shown that the thermal behavior of the reactor follows a first order model. However, an unexpected runaway phenomenon was observed at a frequency of 300Hz. A sudden increase in the power source and consequently in reactor temperature which reaches 170°C is observed. This behavior is discussed in terms of input power variation with temperature, possibly due to a resonance phenomenon.

description: The recent increase in partisan media has generated interest in what drives media outlets to become more partisan. I develop a model where a media outlet can report news with a partisan slant and the news then spread by word of mouth in a population of agents with heterogeneous preferences. The level of slant has an impact on whether the agents find the news credible and on their incentives to pass the news to others. The analysis elucidates how partisanship of media can be driven by political polarisation of the public and by the tendency of people to interact with people with similar political views. Extensions of the model shed light on the influences of social media and the fact that people with different political views tend to trust different media outlets.

description: Objective: Process-based scores of episodic memory tests, such as the recency ratio (Rr), have been found to compare favourably to, or to be better than, most conventional or “traditional” scores employed to estimate memory ability in older individuals (Bock et al., 2021; Bruno et al., 2019). We explored the relationship between process-based scores and hippocampal volume in older adults, while comparing process-based to traditional story recall-derived scores, to examine potential differences in their predictive abilities. Methods: We analysed data from 355 participants extracted from the WRAP and WADRC databases, who were classified as cognitively unimpaired, or exhibited mild cognitive impairment (MCI) or dementia. Story Recall was measured with the Logical Memory Test (LMT) from the Weschler Memory Scale Revised, collected within twelve months of the magnetic resonance imaging scan. Linear regression analyses were conducted with left or right hippocampal volume (HV) as outcomes separately, and with Rr, Total ratio, Immediate LMT, or Delayed LMT scores as predictors, along with covariates. Results: Higher Rr and Tr scores significantly predicted lower left and right HV, while Tr showed the best model fit of all, as indicated by AIC. Traditional scores, Immediate LMT and Delayed LMT, were significantly associated with left and right HV, but were outperformed by both process-based scores for left HV, and by Tr for right HV. Conclusions: Current findings show the direct relationship between hippocampal volume and all the LMT scores examined here, and that process-based scores outperform traditional scores as markers of hippocampal volume.
Magnetic Nanoparticles in a Nematic Channel: A One-Dimensional Study

description: We study a ferromagnetic suspension or a suspension of magnetic nanoparticles in an anisotropic nematic medium, in three different one-dimensional variational settings, ordered in terms of increasing complexity. The three models are featured by a nematic energy, a magnetic energy and a magneto-nematic coupling energy and the experimentally observed patterns are modelled as local or global energy minimizers. We numerically observe polydomains with distinct states of magnetization for weak to moderate magneto-nematic coupling in our models. We demonstrate that these polydomains are stabilised by lowering the temperature (as in Mertelj et al., 2013) and that the polydomain structures lose stability as the magneto-nematic coupling increases. Some exact solutions for prototypical situations are also obtained.

description: Nature features a plethora of extraordinary photonic architectures that have been optimized through natural evolution. While numerical optimization is increasingly and successfully used in photonics, it has yet to replicate any of these complex naturally occurring structures. Using evolutionary algorithms directly inspired by natural evolution, we have retrieved emblematic natural photonic structures, indicating how such regular structures might have spontaneously emerged in nature and to which precise optical or fabrication constraints they respond. Comparisons between algorithms show that recombination between individuals inspired by sexual reproduction confers a clear advantage in this context of modular problems and suggest further ways to improve the algorithms. Such an in silico evolution can also suggest original and elegant solutions to practical problems, as illustrated by the design of counter-intuitive anti-reflective coating for solar cells.

Spain

description: Using a large data set on the population of Spanish municipalities between 1877 and 2001, this paper analyses how their initial size and the presence of neighbouring urban locations influence subsequent population growth and how these links have evolved over time. Our results show that initial size is negatively related to population growth, except in the 1960s and 1970s when this relationship becomes positive. Likewise, the presence of neighbouring urban locations limited local population growth in the late 19th century, a negative effect that persisted, but at a diminishing rate, until the second half of the 20th century. The influence of nearby cities became increasingly positive from then onwards, and especially so during the 1970s.
