The puzzle of the π-> γγ* transition form factor
Creators: name: Lucha, Wolfgang

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the $P\toγ\,γ^*$ ($P=π^0,η,η'$) transition form factors by means of the local-duality (LD) version of QCD sum rules. For the case of $η$ and $η'$, the conventional LD model provides a good description of the existing data. However, for the $π$ form factor we find disagreement with recent BaBar results for high $Q^2$ even though the accuracy of the LD approximation is expected to increase with $Q^2$. It remains mysterious why the $η$ and $η'$ form factors to virtual photons, on the one hand, and the $π$ form factor, on the other hand, show a qualitatively different behaviour corresponding to a rising with $Q^2$ violation of local duality in the pion case. In a quantum mechanical example we show that, for a bound-state size of about 1 fm, the LD sum rule provides an accurate prediction for the form factor for $Q^2\ge$ a few GeV$^2$.

description: We derive general and explicit expressions for the unrenormalized and renormalized dressed propagators of fermions in parity-nonconserving theories with inter-generation mixing. The mass eigenvalues, the corresponding mass counterterms, and the effect of inter-generation mixing on their determination are discussed. Invoking the Aoki-Hioki-Kawabe-Konuma-Muta renormalization conditions and employing a number of very useful relations from Matrix Algebra, we show explicitly that the renormalized dressed propagators satisfy important physical properties.

description: A common application for grease-lubricated oscillating rolling element bearings is, e.g., rotor blade bearings in wind turbines. These bearings mainly operate under conditions that are prone to starvation. If the grease is unable to provide enough inlet lubricant supply for the contact between rolling element and bearing raceway, wear in the form of False Brinelling and thus premature bearing failure is possible. Bearing experiments with different lithium complex model greases, which differ mainly in their base oil viscosity and oil separation rate, were carried out to show the influence of the grease parameters on wear initiation. The results show that the ability of the grease to release a high amount of base oil with high mobility into the track of the rolling element is a crucial mechanism to prevent wear, especially at small oscillation angles. For oscillation angles larger than a critical angle, a secondary replenishment mechanism may prevent early wear initiation. The experimental results are used to validate a starvation model proposed in earlier work (Wandel et al. in Tribol Int 165:107276, 2022).

description: Many organizations are pursuing the implementation of chatbots to enable automation of service processes. However, previous research has highlighted the existence of practical setbacks in the implementation of chatbots in corporate environments. To gain practical insights on the issues related to the implementation processes from several perspectives and stages of deployment, we conducted semi-structured interviews with developers and experts of chatbot development. Using qualitative content analysis and based on a review of literature on human computer interaction (HCI), information systems (IS), and chatbots, we present an implementation framework that supports the successful deployment of chatbots and discuss the implementation of chatbots through a user-oriented lens. The proposed framework contains 101 guiding questions to support chatbot implementation in an eight-step process. The questions are structured according to the people, activity, context, and technology (PACT) framework. The adapted PACT framework is evaluated through expert interviews and a focus group discussion (FGD) and is further applied in a case study. The framework can be seen as a bridge between science and practice that serves as a notional structure for practitioners to introduce a chatbot in a structured and user-oriented manner.

description: We have developed a coarse-grained formulation for modeling the dynamic behavior of cells quantitatively, based on stochasticity and heterogeneity, rather than on biochemical reactions. We treat each reaction as a continuous-time stochastic process, while reducing each biochemical quantity to a binary value at the level of individual cells. The system can be analytically represented by a finite set of ordinary linear differential equations, which provides a continuous time course prediction of each molecular state. In this letter, we introduce our formalism and demonstrate it with several examples.

description: Streptomyces are our principal source of antibiotics, which they generate concomitant with a complex developmental transition from vegetative hyphae to spores. c-di-GMP acts as a linchpin in this transition by binding and regulating the key developmental regulators, BldD and WhiG. Here we show that c-di-GMP also binds the glycogen-debranching-enzyme, GlgX, uncovering a direct link between c-di-GMP and glycogen metabolism in bacteria. Further, we show c-di-GMP binding is required for GlgX activity. We describe structures of apo and c-di-GMP-bound GlgX and, strikingly, their comparison shows c-di-GMP induces long-range conformational changes, reorganizing the catalytic pocket to an active state. Glycogen is an important glucose storage compound that enables animals to cope with starvation and stress. Our in vivo studies reveal the important biological role of GlgX in Streptomyces glucose availability control. Overall, we identify a function of c-di-GMP in controlling energy storage metabolism in bacteria, which is widespread in Actinobacteria.
Distributed Position Localization and Tracking (DPLT) of Malicious Nodes in Cluster Based Mobile Ad hoc Networks (MANET)

Year: 2012

subject: FOS: Computer and information sciences

description: In this paper, a robust distributed malicious node detection and precise localization and tracking method is proposed for Cluster based Mobile Ad hoc Network (MANET). Certificate Authority (CA) node is selected as the most stable node among trusted nodes, surrounded by Registration Authority nodes (RAs) in each cluster to generate the Dynamic Demilitarized Zone (DDMZ) to defend CA from probable attackers and mitigate the authentication overhead. The RAs also co-operate with member nodes to detect a target node and determine whether it is malicious or not, by providing the public key certificate and trust value. In addition, Internet Protocol (IP) based Triangulation and multi-lateration method are deployed based on using the average time difference of Time of Arrival (ToA) and Time of Departure (ToD) of the management packets. Triangulation uses three reference nodes which are elected within each cluster based on Best Criterion Function (BCF) to localize each member node inside the cluster in 2D. Multi-lateration is employed to localize the malicious target node in 2D using four neighbor nodes. After localization of two consecutive positions, the target node is continuously localized and tracked by a particular node using the modified real time Position Localization and Tracking (PL&T) algorithm by adaptive beam forming and mapping the energy contours of tracking zone into coverage radii distance. The performance of the proposed scheme demonstrates the significant accuracy in the detection of malicious nodes within each cluster.

description: We demonstrate a position-sensing technique that relies on the inherent sensitivity of chaos, where we illuminate a subwavelength object with a complex structured radio-frequency field generated using wave chaos and a nonlinear feedback loop. We operate the system in a quasi-periodic state and analyze changes in the frequency content of the scalar voltage signal in the feedback loop. This allows us to extract the object's position with a one-dimensional resolution of ~λ/10,000 and a two-dimensional resolution of ~λ/300, where λ is the shortest wavelength of the illuminating source.

Cutoff rigidity calculations for cosmic ray neutron sensors
Creators: name: Desilets, Darin
Publisher: name: Zenodo
Year: 2021
Subjects: cutoff rigidity, CRNS, cosmic ray, soil moisture

description: The local baseline neutron intensity for a cosmic ray neutron sensor (CRNS) is partly determined by its cutoff rigidity, which is closely related to geomagnetic latitude. The best available methods of calculating cutoff rigidity involve using numerical ray tracing algorithms to find allowed and forbidden trajectories of primary cosmic ray particles. This allows one to precisely determine the lower, upper and effective cutoff values. In this paper we give an overview of the cutoff rigidity calculation methods employed in our online calculators (available at https://crnslab.org) and compare our calculated cutoff values to published values for the same sites and geomagnetic epochs. In CRNS work, cutoff rigidity calculations are used in scaling the calibration parameter N0 to new locations, or in scaling various N0 values to a common location for the sake of comparison. Such comparisons of N0 are valuable in work with both stationary and mobile CRNS.

The slab is illuminated by coherent light from both sides, at the same angle of incidence and the conditions required for CPA are investigated as a function of the different geometrical parameters. The simultaneous realization of CPA at two distinct frequencies is also shown. Finally, our calculations clearly elucidate the role of absorption as a necessary prerequisite for CPA.

description: Fourier transforming the virtual photon transverse momentum in γ*(q)+N \to f processes allows new insight into hadron dynamics as a function of impact parameter b. I discuss how previous analyses of charge density based on elastic and transition form factors (f=N, N*) can be generalized to any multi-hadron final state (f=πN, ππN, \bar D Λ_c,...). The b-distribution determines the transverse positions of the quarks that the photon couples to, and can be studied as a function of multiplicity, the relative transverse momenta, quark masses and polarization. The method requires no factorization nor leading twist approximation. Data with spacelike photon virtualities in the range 0 < Q < Q_{max} provides a resolution Δb > 1/Q_{max} in impact parameter.

"What they are doing to the land they are doing to us" : environmental politics on Haida Gwaii
Creators: name: Dean, Michael
Publisher: name: University of British Columbia
Year: 2009

description: This paper discusses the development of Native environmental politics on Haida Gwaii, also known as the Queen Charlotte Islands, since the late 1970’s. During that time, concerns among the Haida about the impacts of industrial logging on their culture led to the emergence of a sustained, innovative challenge to the existing regime of resource extraction on the islands as well as the larger colonial structures on which it was premised. As a result, environmental activism became a means for the Haida to pursue decolonization outside the official channels of the land claims process. In particular this paper focuses on the conflict surrounding logging in the area of South Moresby Island culminating in the creation of the Gwaii Haanas National Park, which was the first National Park to be co-managed by the Government of Canada and an indigenous nation. By tracing the development of environmental activism on Haida Gwaii it contributes to an understanding of the ways that recent Native environmental movements have formulated indigenous identity and drawn on cultural traditions as well as their experience of colonialism. It also contributes to debates surrounding co-management and TEK by showing how the development of Haida environmental management structures occurred in conjunction with the development of a Haida environmental politics without which it would not have been capable of delivering on its liberatory promise.

description: Traffic crashes are one of the major causes of deaths at work. However, most of the literature on traffic crashes did not study the influence of worker and organization conditions. The current paper analyses the influence of the personal and organizational factors associated with the severity of occupational traffic crashes. A total of 724,596 occupational traffic crashes that occurred in Spain from 2009 to 2019 were analyzed. Men suffered 59% of crashes registered, while workers younger than 30 represented 31.3% of crashes studied. Variables included in the Official Occupational Accident Report were analyzed using logistic regression calculating odds ratios. Results showed that a foreign, professional male driver from a small company who is older than 55 years was more likely to suffer a fatal crash. In contrast, a Spanish, nonprofessional female driver from a medium or big company who is younger than 30 years is more likely to suffer light consequences. Findings from the current research could help to improve the safety training programmes in companies considering their personal and business variables such as age, gender, or company staff, especially in small companies. Future research should collect and analyze additional variables combining different data sources.

Neurologische Modelle und theoretische Überlegungen für eine physikalische Realisierung der Elektronik werden in die Untersuchungen einbezogen und Modellrechnungen zur Erhöhung der Elektrodenanzahl, zur Bestimmung der sicheren Stimulations¬bereiche und zur pixelweisen Stimulation vorgestellt. Weiterhin werden physikalischen Aspekte von Phosphenen diskutiert. Die Modellrechnungen werden mit Hilfe von experimentellen Ergebnissen aus der Literatur verifiziert.
description: Visual prosthesis aims to restore vision to those affected by sight-robbing illnesses. Although government-approved vision devices provide advantageous sight enhancements, visual and spatial perception of electrically activated cells requires significant improvement for delivering functional vision. High-level theoretical studies of electrode arrangements and of realistic neural responses in the retina are modeled for enhancing visual perception. Computational efficiency in neural modeling and deep theoretical thinking for a possible physical realization of electronics are considered. The theoretical viability of increasing electrode sites, safe avenues of stimulation that guarantee electrochemical safety and pixel-wise stimulation are met. The understanding of the physical aspects of phosphenes is addressed. Neural modeling is verified by means of experimental studies from literature.

description: Occupant kinematics and biomechanical responses are assessed with and without pretensioning of normally seated and out-of-position front-seat occupants in rear sled tests. The results are compared to recent studies. Three series of rear sled tests were conducted at 24 and 40 km/h with a 2001 Ford Taurus. Series I consisted of two sled tests with a lap-shoulder belted 50th Hybrid III in the driver seat. Series II included four sled tests with a lap-shoulder belted 50th Hybrid III in both front seats. Two soft foam blocks were added, one was placed on the chest centerline under the shoulder belt and one on the pelvis under the lap belt providing additional webbing. Series III consisted of 8 runs and 16 ATD tests to assess the effect of pretensioning with out-of-positioned (OOP) occupants. The biomechanical responses were normalized with Injury Assessment Reference Values (IARV) for head, neck and chest. The ATD kinematics and biomechanical responses were similar in the yielding phase when the occupant was normally seated with and without pretensioning. The rebound displacement was greater with pretensioning in the 40 km/h tests due to the shoulder belt slipping off the shoulder. The hip displacement was similar, irrespective of pretensioning. All biomechanical responses were below IARVs. The highest response was for lower neck extension. The normalized response was at about 32% for the 24 km/h tests, irrespective of pretensioning. It was up to 59% in the 40 km/h tests with pretensioning. With the OOP occupants, there were no differences in the kinematics and biomechanical response with pretensioning. Testing of the effect of retractor pretensioning with out-of-position occupants and additional belt webbing in moderate to high-speed rear sled tests shows no effect on occupant kinematics and biomechanical responses. The displacement of the hips in a rear impact depends on the compliance of the seatback and amount of pocketing, the stiffness of the seat frame limiting rearward rotation, and the dynamic friction between the occupant and the seatback.

description: A large body of research has established that cellphone use while driving (CUWD) is common and dangerous. However, little research has been conducted about how people react psychologically to various distraction-reduction strategies and, ultimately, support or do not support them. Understanding support for reduction is important for predicting use of technological solutions and compliance with laws and for improving communication and education about the risks of CUWD. We measured support for a variety of legislative, technological, and organizational strategies to reduce CUWD in an online sample of American drivers (N = 648). We also developed evidence-based communication techniques, describing strategies in terms of benefits vs. costs or using freedom-invoking vs. freedom-reducing language to assess what would influence support. Support for CUWD reduction was generally high. It was predicted by driver characteristics and beliefs. For example, drivers who supported reducing CUWD more also had lower CUWD reactance, greater anti-CUWD beliefs, higher personal risk perceptions of CUWD, and greater self-reported distracted driving. Age and perceived ability to drive distracted did not predict overall support. However, two strategies that allow for handsfree phone use were supported more by people who engaged in more CUWD, perceived they had greater ability to CUWD, perceived more benefits to CUWD, had more positive affect to cellphones, and were younger. Communication techniques also influenced support. Specifically, the same strategy was supported more when described using benefits and permissive language instead of costs and restrictive language. Most respondents supported strategies to reduce CUWD, and beliefs about risks and benefits predicted this snupport. Reactance to CUWD messaging emerged as a key predictor of lower support (and of greater self-reported distracted driving), indicating that it could be an important variable to consider when designing strategies to reduce CUWD. When targeting people resistant to quitting CUWD entirely, communicators could recommend a switch to handsfree use. Communicators who emphasize benefits and use permissive language also may increase support for CUWD reduction.

description: Powerpoint presentation for the Knowledge Graph Conference 2023 The Error is the Message: Extracting Insights from Deceptive Data for Nazi looted art Turning dross into gold. Knowledge graphs, with their capacity for surfacing vast hidden networks, can help detect looted art from the ownership history – or provenance – of artworks. The cultural heritage sector and art industry have explored named entity recognition with an event-based approach using CIDOC-CRM. However, Nazi-looted art poses a particular challenge, in part due to the passage of time, and in part due to unreliable data, as attempts to conceal and distort information which began in the Nazi era continue into the digital age. Missing, confusing or badly coded entities, false dates, names, events, places, the mixing of speculation and fact occur with such frequency in Nazi-looted art that it is useful to view errors, not as anomalies to be cleansed from the dataset, but as primary features to be analyzed. This presentation focuses on strategies and methods to quantify, classify, code and exploit this unreliable information in order to detect looted art and the patterns and networks which underly its commercialisation.

description: We study the different response to an impurity of the two topologically different phases shown by a two dimensional insulator with time reversal symmetry, namely, the Quantum Spin Hall and the normal phase. We consider the case of graphene as a toy model that features the two phases driven, respectively, by intrinsic spin-orbit coupling and inversion symmetry breaking. We find that strictly normalizable in-gap impurity states only occur in the Quantum Spin Hall phase and carry dissipationless current whose quirality is determined by the spin and pseudospin of the residing electron. Our results imply that topological order can be unveiled by local probes of defect states.

description: Motivated by recent studies of deep inelastic scattering (DIS) off the $\mathcal{N}=4$ super-Yang-Mills (SYM) plasma, holographically dual to $AdS_5\times S^5$ black hole, we in this note use the spacelike flavor current to probe the internal structure of one holographic quark-gluon plasma, which is described by the Sakai-Sugimoto model at high temperature phase (i.e., the chiral symmetric phase). The plasma structure function is extracted from the retarded flavor current-current correlator. Our main aim here is to explore the effect of non-conformality on these physical quantities. As usual, our study is under the supergravity approximation and the limit of large color number. Although the Sakai-Sugimoto model is non-conformal, which makes the calculations more involved than the well-studied $\mathcal {N}$=4 SYM case, the result seems to indicate that the non-conformality has little essential effect on the physical picture of the internal structure of holographic plasma, which is consistent with the intuition from the asymptotic freedom of QCD at high energy. While the physical picture underlying our investigation is same as the DIS off the $\mathcal {N}$=4 SYM plasma with(out) flavor, the plasma structure functions are quantitatively different, especially their scaling dependence on the temperature, which can be recognized as model-dependent. As a comparison, we also do the same analysis for the non-critical version of the Sakai-Sugimoto model which is conformal in the sense that it has a constant dilaton vacuum. The result for this non-critical model is much similar to the conformal $\mathcal{N}=4$ SYM plasma. We therefore attribute the above difference to the effect of non-conformality of the Sakai-Sugimoto model.

description: To examine the effect of age on the dynamic performance of child restraint systems in frontal crashes. A sample of used (3-269 months from manufacture) and newly purchased child restraints were subjected to frontal crash simulations of more than 56 km/h and peak deceleration approximately 33 g on a deceleration sled. Restraints were monitored for evidence of damage before and after each impact. Anthropometric test device (ATD) head and chest responses and peak head excursions were recorded for rearward facing restraints using the Q1 ATD and for forward facing restraints and booster seats using the Q6 ATD. The influence of restraint age on peak 3 ms head acceleration, HIC15, head excursion, peak 3 ms chest acceleration and restraint damage were analyzed. In all impacts, the ATD remained within the restraint and secured to the test bench demonstrating the crash protection offered by the old and used restraints. There was no apparent relationship between ATD responses and restraint age for any restraint type. Older forward facing restraint systems had a very modest increase in forward head excursion (R2 = 0.59, p = 0.001) of 0.27 mm for each month of age (95% CI, 0.13 mm − 0.42 mm). This equates to a 0.7% increase in the minimum measured excursion per year of restraint age. There was also a small increased likelihood of critical damage to the restraints in the simulated crashes per month of restraint age (OR 1.031, 95% CI 1.010-1.069). Overall, degradation in restraint dynamic performance in older restraints, including some that are much older than the currently recommended 10-year lifetime, is minimal. However newer restraints may provide better protection due to marginal improvements in restraint design over time. Furthermore, the results of this study confirm previous recommendations that restraints should not be re-used after crash involvement.

description: Recently, Srimani and Xu presented a self-stabilizing algorithm that computes a weakly connected minimal dominating set. They prove an upper bound of O(2^n) until stabilization but they do not provide a lower bound. This paper verifies by giving an example that their algorithm indeed requires O(2^n) moves on a certain graph.

description: We establish a sharp extrinsic lower bound for the first eigenvalue of the Dirac operator of an untrapped surface in initial data sets without apparent horizon in terms of the norm of its mean curvature vector. The equality case leads to rigidity results for the constraint equations with spherical boundary as well as uniqueness results for constant mean curvature surfaces in Minkowski space.

description: We consider the problem of electron transport in segregated conductor-insulator composites in which the conducting particles are connected to all others via tunneling conductances, thus forming a global tunnelingconnected resistor network. Segregation is induced by the presence of large insulating particles, which forbid the much smaller conducting fillers from occupying uniformly the three-dimensional volume of the composite. By considering both colloidal-like and granular-like dispersions of the conducting phase, modeled respectively by dispersions in the continuum and in the lattice, we evaluate by Monte Carlo simulations the effect of segregation on the composite conductivity σ, and show that an effective-medium theory applied to the tunneling network reproduces accurately the Monte Carlo results. The theory clarifies that the main effect of segregation in the continuum is that of reducing the mean interparticle distances, leading to a strong enhancement of the conductivity. In the lattice-segregation case the conductivity enhancement is instead given by the lowering of the percolation thresholds for first and beyond-first nearest neighbors. Our results generalize to segregated composites the tunneling-based description of both the percolation and hopping regimes introduced previously for homogeneous disordered systems.

description: We present Swift UVOT and XRT observations, and visual wavelength spectroscopy of the Type IIb supernova (SN) 2009mg, discovered in the Sb galaxy ESO 121-G26. The observational properties of SN 2009mg are compared to the prototype Type IIb SNe 1993J and 2008ax, with which we find many similarities. However, minor differences are discernible including SN 2009mg not exhibiting an initial fast decline or u-band upturn as observed in the comparison objects, and its rise to maximum is somewhat slower leading to slightly broader light curves. The late-time temporal index of SN 2009mg, determined from 40 days post-explosion, is consistent with the decay rate of SN 1993J, but inconsistent with the decay of 56Co. This suggests leakage of gamma-rays out of the ejecta and a stellar mass on the small side of the mass distribution. Our XRT non-detection provides an upper limit on the mass-loss rate of the progenitor of <1.5x10^-5 Msun per yr. Modelling of the SN light curve indicates a kinetic energy of 0.15 (+0.02,-0.13) x10^51 erg, an ejecta mass of 0.56(+0.10,-0.26) Msun and a 56Ni mass of 0.10\pm0.01 Msun.

From the internal to the external : a selected translation and study of four archaeological texts and their account of human nature

description: This thesis covers four of the Confucian bamboo strip manuscripts discovered in the Guodian archaeological site: Liude, Xing zi ming chu, Cheng zhi wen zhi and Zun deyi. Much of the scholarship to date on the Guodian manuscripts has treated all of the Confucian texts as a unit, or has examined each text in isolation, ignoring the potential differences and similarities between individual texts or groups of texts within this corpus. This thesis is intended to address this problem by investigating the conceptual themes that connect these four texts into a single, coherent philosophy. Because the four texts addressed in this thesis appear to have been originally bound together into a single bundle of bamboo strips, they present an ideal starting point for this investigation. Chapter One examines the distinction made between the biological relationships of the family and the non-biological relationships of the social and political world, and how this affects people's innate emotional dispositions. Chapter Two considers the question of human nature as it was understood at the time, and the possibility that these texts were written as a response to the concept of human nature that had been recently proposed by rival philosophers. Chapter Three examines how these fundamental questions of biology, society and human nature form the foundation of a political philosophy, and how later thinkers would adopt the rhetoric of this philosophy, but would do away with the fundamentally Confucian beliefs that underlie the political vision of these four specific texts.
