WZWZ Production at eγe\gamma Colliders and Anomalous Quartic WWZγWWZ\gamma Coupling

We investigate the constraints on the anomalous quartic $W^{+}W^{-}Z\gamma$ gauge boson coupling through the process $e^{-}\gamma\to \nu_{e}W^{-}Z$. Considering incoming beam polarizations and the longitudinal and transverse polarization states of the final W and Z boson we find 95% confidence level limits on the anomalous coupling parameter $a_{n}$ with an integrated luminosity of 500 $fb^{-1}$ and $\sqrt{s}$=0.5, 1 TeV energies. We show that initial beam and final state polarizations improve the sensitivity to the anomalous coupling by up to factors of 2 - 3.5 depending on the energy.Comment: published versio

Seismotectonic, structural, volcanologic, and geomorphic study of New Zealand; indigenous forest assessment in New Zealand; mapping, land use, and environmental studies in New Zealand, volume 2

The author has identified the following significant results. Ship detection via LANDSAT MSS data was demonstrated. In addition, information on ship size, orientation, and movement was obtained. Band 7 was used for the initial detection followed by confirmation on other MSS bands. Under low turbidity, as experienced in open seas, the detection of ships 100 m long was verified and detection of ships down to 30 m length theorized. High turbidity and sea state inhibit ship detection by decreasing S/N ratios. The radiance effect from snow of local slope angles and orientation was also studied. Higher radiance values and even overloading in three bands were recorded for the sun-facing slope. Local hot spots from solar reflection appear at several locations along transect D-C in Six Mile Creek Basin during September 1976

The author has identified the following significant results. As part of the tape reformatting process, a simple coded picture output program was developed. This represents Pixel's radiance level by one of a 47 character set on a nonoverprinting line printer. It not only has aided in locating areas for the reformatting process, but has also formed the foundation for a supervised clustering package. This in turn has led to a simplistic but effective thematic mapping package

The author has identified the following significant results. Inspection of pixels obtained from LANDSAT of New Zealand revealed that not only can ships and their wakes be detected, but that information on the size, state of motion, and direction of movement was inferred by calculating the total number of pixels occupied by the vessel and wake, the orientation of these pixels, and the sum of their radiance values above the background level. Computer enhanced images showing the Waimihia State Forest and much of Kaingaroa State Forest on 22 December 1975 were examined. Most major forest categories were distinguished on LANDSAT imagery. However, the LANDSAT imagery seemed to be most useful for updating and checking existing forest maps, rather than making new maps with many forest categories. Snow studies were performed using two basins: Six Mile Creek and Mt. Robert. The differences in radiance levels indicated that a greater areal snow cover in Six Mile Creek Basin with the effect of lower radiance values from vegetation/snow regions. A comparison of the two visible bands (MSS 4 and 5) demonstrate this difference for the two basins

The author has identified the following significant results. Results of the atmospheric extinction measurements show clearly the greater opacity of the atmosphere in MSS band 4 which is due to Rayleigh scattering. Atmospheric water vapor absorbs strongly in a wide region between 900 nm and 1000 nm, and this results in a consistently higher extinction coefficient than would otherwise be expected in MSS band 7. The short term fluctuations tend to be greater in band 7 than in the other bands, and this effect is probably due to variations of water vapor concentration in the instrument line of sight. These high extinction coefficients and short term fluctuations in band 7 were observed at Menindee which is in a semi-desert region in western New South Wales

The inner radio jet region and the complex environment of SS433

We present multi-frequency VLBA+VLA observations of SS433 at 1.6, 5 and 15 GHz. These observations provide the highest angular resolution radio spectral index maps ever made for this object. Motion of the components of SS433 during the observation is detected. In addition to the usual VLBI jet structure, we detect two radio components in the system at an anomalous position angle. These newly discovered radio emitting regions might be related to a wind-like equatorial outflow or to an extension of the accretion disk. We show that the radio core component is bifurcated with a clear gap between the eastern and western wings of emission. Modelfitting of the precessing jets and the moving knots of SS433 shows that the kinematic centre -- i.e. the binary -- is in the gap between the western and eastern radio core components. Spectral properties and observed core position shifts suggest that we see a combined effect of synchrotron self-absorption and external free-free absorption in the innermost AU-scale region of the source. The spatial distribution of the ionized matter is probably not spherically symmetric around the binary, but could be disk-like.Comment: Accepted for publication by Astronomy and Astrophysic

Extended Bell and Stirling numbers from hypergeometric exponentiation

Exponentiating the hypergeometric series 0FL(1,1,...,1;z), L = 0,1,2,..., furnishes a recursion relation for the members of certain integer sequences bL(n), n = 0,1,2,.... For L >= 0, the bL(n)'s are generalizations of the conventional Bell numbers, b0(n). The corresponding associated Stirling numbers of the second kind are also investigated. For L = 1 one can give a combinatorial interpretation of the numbers b1(n) and of some Stirling numbers associated with them. We also consider the L>1 analogues of Bell numbers for restricted partitions

Why cartoons make (some of) us smile

Pocket cartoons are a regular feature of most contemporary newspapers and magazines. As such, they represent a way of conveying complex social and political commentary in a simple visual form. How well we enjoy verbal (oral) jokes depends on the number of mindstates in the joke, and here we ask whether this is also true of visual cartoons. We use survey data from a sample of 3,380 participants attending a public exhibition of published print media cartoons by well-known cartoonists to determine the extent to which viewers’ ratings of cartoons are determined by the mentalizing content of cartoons, the participants’ gender and age, and the publication date of the cartoon. We show that the number of mindstates involved in the cartoon affects its appreciation, just as in verbal jokes. In addition, we show that preferred topics vary by age and gender. While both genders strongly prefer cartoons that explore the complexities of romantic relationships, men rate visual jokes more highly than women do, whereas women prefer jokes that involve political commentary or the dynamics of close relationships. These differences seem to reflect differences in the way the social worlds of the two genders are organized

Re-estimating the Size of the Polar Bear Population in Western Hudson Bay

A mark-recapture study of polar bears (Ursus maritimus) ashore during the ice-free period of Hudson Bay was undertaken in 1994 and 1995 to re-estimate the size of the western Hudson Bay population. Previous estimates were based on animals caught between the Churchill and Nelson Rivers; consequently, bears in the southern part of the geographic range of this population were not sampled. We used Jolly-Seber models to re-estimate population size from two data sets: bears handled between the Churchill and Nelson Rivers from 1984 to 1995 and bears handled between Churchill and the Manitoba-Ontario border from 1984 to 1986 and by us in 1994 and 1995. Both data sets gave similar estimates. Thus, our best estimate of the size of the western Hudson Bay polar bear population is 1200 ±250 animals in autumn 1995.En 1994 et 1995, on a entrepris une étude sur la reprise d'ours polaires (Ursus maritimus) étiquetés sur la terre ferme durant la période libre de glace dans la baie d'Hudson, en vue d'établir une nouvelle estimation de la taille de la population dans la partie ouest de cette baie. Les estimations précédentes s'appuyaient sur le nombre d'animaux pris entre les fleuves Churchill et Nelson; par conséquent, les ours situés dans la partie méridionale de l'étendue géographique de cette population n'ont pas fait l'objet d'un échantillonnage. On s'est servi de modèles Jolly-Seber pour établir une nouvelle estimation de la taille de la population à partir de deux ensembles de données: des ours marqués entre le Churchill et le Nelson de 1984 à 1995, et des ours marqués entre le Churchill et la frontière Manitoba-Ontario de 1984 à 1995. Ces derniers prélèvements renfermaient des données sur la reprise d'ours étiquetés effectuée de 1984 à 1996 par le ministre ontarien des Ressources naturelles le long de la côte est du Manitoba, et par nous-mêmes en 1994 et 1995. Les deux ensembles de données fournissaient des estimations similaires. Ainsi, pour l'automne 1995, notre estimation la plus précise de la taille de la population de l'ours polaire dans l'ouest de la baie d'Hudson est de 1200 ± 250 individus

Beyond agriculture: alternative geographies of rural land investment and place effects across the United Kingdom

Global land ownership patterns have been shifting in recent decades, as institutional and non-traditional investors redirect capital into rural areas. Such investment is a stimulating alternative for innovative profit-driven land uses that move beyond agriculture. This paper explores how ‘new money’ economies have created place effects in three rural case studies across the United Kingdom, through concepts of built, natural, social, and economic capital. The case studies are informed by secondary research, site visits, and interviews, providing snapshots of investment impact. They represent diverse transformations in rural land use via new forms of direct investment, active investment, and processes of financing rather than financialisation, with distinct spatial and temporal characteristics. The case studies include new wine production in Kent, England; transforming the Menie Estate into Trump International Golf Links Scotland (TIGLS); and farm diversification in Northern Ireland. The conclusions tell three investment stories, where place effects reflect the dichotomies, contestation, and symbiosis between investors and local contexts. New land uses create place effects where economic potential often conflicts with natural capital impacts, although they foster knowledge creation and exchange. The underlying values of the investors and their navigation of local politics also have key roles to play in shaping the built, natural, social, and economic place effects
