description: Aiming at the local overload of multi-controller deployment in software-defined networks, a load balancing mechanism of SDN controller based on reinforcement learning is designed. The initial paired migrate-out domain and migrate-in domain are obtained by calculating the load ratio deviation between the controllers, a preliminary migration triplet, contains migration domain mentioned above and a group of switches which are subordinated to the migrate-out domain, makes the migration efficiency reach the local optimum. Under the constraint of the best efficiency of migration in the whole and without migration conflict, selecting multiple sets of triples based on reinforcement learning, as the final migration of this round to attain the global optimal controller load balancing with minimum cost. The experimental results illustrate that the mechanism can make full use of the controllers' resources, quickly balance the load between controllers, reduce unnecessary migration overhead and get a faster response rate of the packet-in request.

description: The safety of electrical power system facilities is one of the most important characteristics of operational efficiency. The importance of safety is shown, first of all, that their discrepancy to shown requirements results not only in the big material damage, but also to infringement of ecology, a traumatism and destruction of the personnel serving object. Increase of efficiency of the control and the analysis of execution of Safety rules can be reached on the basis of computer technologies, by transition from the qualitative characteristic of safety to quantitative. The initial stage of increase of safety of objects of electro power systems is transition to modelling control samples Fire Safety rules, to a substantiation of volume samples and to documentary acknowledgement of execution of Safety rules.

description: In this article we show how some known to us measures of dependence between random events can be easily transferred into measures of local dependence between random variables. This enables everyone to see and visually evaluate the local dependence between uncertain units on every region of their particular values. We believe that the true value of the use of such dependences is in applications on nonnumeric variables, as well as in finances and risk studies. We also trust that our approach may give a serious push into the microscopic analysis of the pictures of dependences offered in big data. Numeric and graphical examples should confirm the beauty, simplicity and the utility of this approach, especially in reliability models.

description: We consider orthogonal polynomials $\{p_{n,N}(x)\}_{n=0}^{\infty}$ on the real line with respect to a weight $w(x)=e^{-NV(x)}$ and in particular the asymptotic behaviour of the coefficients $a_{n,N}$ and $b_{n,N}$ in the three term recurrence $x π_{n,N}(x) = π_{n+1,N}(x) + b_{n,N} π_{n,N}(x) + a_{n,N} π_{n-1,N}(x)$. For one-cut regular $V$ we show, using the Deift-Zhou method of steepest descent for Riemann-Hilbert problems, that the diagonal recurrence coefficients $a_{n,n}$ and $b_{n,n}$ have asymptotic expansions as $n \to \infty$ in powers of $1/n^2$ and powers of $1/n$, respectively.

description: In healthcare related problems there exist some medical error due to involvement of human errors and technologies error. In general the available data is not sufficient to assess the clinical process. This study uses level (𝜆,𝜌) intervalued trapezoidal fuzzy numbers and their functional to evaluate the estimate reliability of system in the fuzzy sense, In this paper we uses fault tree diagram of the mixed system (series and parallel system) and we change their crisp probability to trapezoidal fuzzy number and a new approach of functional of fuzzy number has developed and Computed results have been compared with results obtained from other existing techniques.

description: There is a longstanding discrepancy between the observed Galactic classical nova rate of $\sim 10$ yr$^{-1}$ and the predicted rate from Galactic models of $\sim 30$--50 yr$^{-1}$. One explanation for this discrepancy is that many novae are hidden by interstellar extinction, but the degree to which dust can obscure novae is poorly constrained. We use newly available all-sky three-dimensional dust maps to compare the brightness and spatial distribution of known novae to that predicted from relatively simple models in which novae trace Galactic stellar mass. We find that only half ($\sim 48$\%) of novae are expected to be easily detectable ($g \lesssim 15$) with current all-sky optical surveys such as the All-Sky Automated Survey for Supernovae (ASAS-SN). This fraction is much lower than previously estimated, showing that dust does substantially affect nova detection in the optical. By comparing complementary survey results from ASAS-SN, OGLE-IV, and the Palomar Gattini IR-survey in the context of our modeling, we find a tentative Galactic nova rate of $\sim 40$ yr$^{-1}$, though this could decrease to as low as $\sim 30$ yr$^{-1}$ depending on the assumed distribution of novae within the Galaxy. These preliminary estimates will be improved in future work through more sophisticated modeling of nova detection in ASAS-SN and other surveys.

description: This research work investigates an optimal software release problem via phase type distribution, warranty and risk cost analysis. The inter arrival time of software failure is assumed to be a phase type distribution. The PH-SRM is one of the most flexible models, which overarches the existing non-homogeneous Poisson process (NHPP) models, and can approximate any type of NHPP-based models with high accuracy. Based on the phase type Nonhomogeneous Poisson Process (PHNHPP) formulation and using the renewal reward theorem, the long run average cost rate is obtained. As model parameter estimation is an important issue in developing software reliability models, the software failure parameter has been estimated by the moment matching method. Finally, a numerical example is provided to illustrate the theoretical results therein.
Selection Bias in Observing the Cosmological Evolution of the Mbh-sigma and Mbh-L Relationships

description: Programs to observe evolution in the Mbh-sigma or Mbh-L relations typically compare black-hole masses, Mbh, in high-redshift galaxies selected by nuclear activity to Mbh in local galaxies selected by luminosity L, or stellar velocity dispersion sigma. Because AGN luminosity is likely to depend on Mbh, selection effects are different for high-redshift and local samples, potentially producing a false signal of evolution. This bias arises because cosmic scatter in the Mbh-sigma and Mbh-L relations means that the mean log(L) or log(sigma) among galaxies that host a black hole of given Mbh, may be substantially different than the log(L) or log(sigma) obtained from inverting the Mbh-L or Mbh-sigma relations for the same nominal Mbh. The bias is particularly strong at high Mbh, where the luminosity and dispersion functions of galaxies are falling rapidly. The most massive black holes occur more often as rare outliers in galaxies of modest mass than in the even rarer high-mass galaxies, which would otherwise be the sole location of such black holes in the absence of cosmic scatter. Because of this bias, Mbh will typically appear to be too large in the distant sample for a given L or sigma. For the largest black holes and the largest plausible cosmic scatter, the bias can reach a factor of 3 in Mbh for the Mbh-sigma relation and a factor of 9 for the Mbh-L relation. Unfortunately, the actual cosmic scatter is not known well enough to correct for the bias. Measuring evolution of the Mbh and galaxy property relations requires object selection to be precisely defined and exactly the same at all redshifts.

description: We study individual behavior of students and workers in an experiment where they repeatedly faced with the same cooperative task. The data show that clerical workers differ from college students in overall cooperation rates, strategies adopted, and use of punishment opportunities. Students cooperate more than workers, and cooperation increases in both subject pools when a personal punishment option is available.
Students are less likely than workers to adopt strategies of unconditional defection and more likely to select strategies of conditional cooperation. Finally, students are more likely than workers to sanction uncooperative behavior with decentralized punishment and also personal punishment when available.

description: No abstracts are to be cited without prior reference to the author.During bottom trawl research surveys of the NE Atlantic continental slope, the macrourid Nezumia aequalis was fourtd to be common and widespread in the 750 - 1000 m depth zones. Although it has no commercial value, due to it's small adult size (total length -30 cm), it is nevertheless large enough to be retained by commercial trawls targeting marketable species such as the roundnose grenadier Coryphaenoides rupestris and deep-water sharks (e.g. Centroscymnus crepidater and C. coelolepis). Nezumia aequalis is therefore seen to be an important component of the fish assemblage of the continental slope and a species which is impacted by commercial fishing operations, but little has been reported ofits biology in this area. The breeding season extends over the first three quarters of the year, mature ovaries containing five size groups of eggs suggesting serial batch spawning. Total egg count ranged from 2109 to 26 847 and was strongly correlated with body size. Age, as determined from whole and sectioned otoliths, ranged from 1 to IO years, the ageing methods being validated by a time-series study of the otolith edge. Growth was slow and maximum size small (von-Bertalanffy parameters: k=0.175, L.inf=676 cm head length), females attaining a larger adult size than males.

description: No abstracts are to be cited without prior reference to the author.This paper presents some biological parameters of the black dogfish ( C fabricii) and the greater lantern shark (E. princeps) based on material collected during surveys of Marine Research Institute, Iceland. C. fabricii was· observed with the greatest abundance in depths between 800 and 1200 m (range 436 to 1653 m). The overall sex ratio was 1.00:1.19 in favour of females. Males were niore numerous in shallower waters but in depths below I 000 m, the sex ratio was significantly in favour of females. E. princeps was observed in depths with the greatest density between 800 and 1000 m (range 436 to 1653 m). The overall sex ratio was 1.00: 1.59 in favour of females, females being ,significantly more numerous in depths below 1000 m. For both species the tendency of decreasing length with increasing depths was observed. Further, there is an indication of sexual dimorphism in both species i.e; females become larger than males and are larger at maturity. Maturity stages were observed during two seasons arid indicated that neither of these two species have a defined breeding season. A study of the diets showed that larger specimens of C.fabricii fed mainly on teleosts but smaller specimens seemed to feed more opportunistically on teleosts, cephalopods and crustaceans.E . princeps seemed to feed mainly on three prey categories; teleosts, cephalopods and crustaceans.A considerable amount of these two species, especially of C. fabricii could be discarded on fishing grounds of Reinhardtius hippoglossoides off West Iceland.

description: Thermoelectric cells convert directly heat into electricity but, due to the low conversion efficiency (up to 5%), most applications are in waste heat recovery. Another promising application is in biomass boiler. In this case, the installation of thermoelectric modules converts a biomass boiler into a cogeneration system, where the aim of the integration is not the electricity production for external power supply, but the realization of a stand-alone biomass power plant which could match the customer needs in isolated places. This review is focused on the recent research papers in thermoelectric biomass cogeneration.

Έβρου. Ιδιαίτερη έμφαση δόθηκε στο Τρυγόνι εξαιτίας του δυσμενούς καθεστώτος διατήρησης του. Η κατανομή και η παρουσία των τεσσάρων ειδών βρέθηκε ότι καθορίζεται κυρίως από το ενδιαίτημα, ενώ δε βρέθηκε να επηρεάζεται από τις μεταξύ τους διαειδικές αλληλεπιδράσεις. Τα μοντέλα μέγιστης εντροπίας, προέβλεψαν με ακρίβεια τις βέλτιστες περιοχές του κάθε είδους στο Ν. Έβρου. Ωστόσο, οι μισές και πλέον βέλτιστες περιοχές για το Τρυγόνι εντοπίζονται εκτός του δικτύου Προστατευόμενων Περιοχών. Η αφθονία του Τρυγονιού παρουσίαζε παρόμοιες αποκρίσεις στα διάφορα χαρακτηριστικά του περιβάλλοντος με αυτές της παρουσίας, αλλά δε συσχετιζόταν με το βαθμό καταλληλότητας των ενδιαιτημάτων. Επιπλέον, η δομή του αναπαραγωγικού ενδιαιτήματος του Τρυγονιού παρουσίασε σημαντικές χρονικές μεταβολές. Επίσης, η μορφολογία της φτερούγας των ώριμων και των ανώριμων Τρυγονιών βρέθηκε ότι διαμορφώνεται από διαφορετικές δυνάμεις επιλογής. Τέλος, με βάση τα αποτελέσματα της διατριβής προτείνεται μια σειρά από μέτρα που πιθανόν να συμβάλουν στην αποτελεσματικότερη διαχείριση των μελετώμενων ειδών και των ενδιαιτημάτων τους.
description: The aim of this thesis was to investigate the spatial ecology of four columbid species (Streptopelia turtur, S. decaocto, Columba palumbus και C. livia dom.) found in Evros district. More emphasis was given to the Turtle Dove due to its deteriorating population status. Each species’ distribution was mainly driven by habitat, while interspecific interactions did not seem to have any influence. Maximum entropy modeling was able to accurately predict areas of suitable habitat for each species. However, more than half of the Turtle Dove’s suitable areas were located outside of the Protected Area network boundaries. Turtle Dove’s abundance showed similar responses to environmental features as those of the niche model, but abundance did not illustrate a strong correlation with the degree of habitat suitability. Moreover, Turtle Dove’s occurrence and breeding habitat vegetation structure underwent significant temporal changes. In addition, examination of the species’ wing morphology showed that juvenile individuals may be more prone to predation than adults. Finally, based on the overall results of this thesis, several measures for the effective management and conservation of the studied species and their habitats are proposed.

description: Convolutional neural network training can suffer from diverse issues like exploding or vanishing gradients, scaling-based weight space symmetry and covariant-shift. In order to address these issues, researchers develop weight regularization methods and activation normalization methods. In this work we propose a weight soft-regularization method based on the Oblique manifold. The proposed method uses a loss function which pushes each weight vector to have a norm close to one, i.e. the weight matrix is smoothly steered toward the so-called Oblique manifold. We evaluate our method on the very popular CIFAR-10, CIFAR-100 and ImageNet 2012 datasets using two state-of-the-art architectures, namely the ResNet and wide-ResNet. Our method introduces negligible computational overhead and the results show that it is competitive to the state-of-the-art and in some cases superior to it. Additionally, the results are less sensitive to hyperparameter settings such as batch size and regularization factor.
The effect on perception of pain sensation, distress and incentive spirometry performance when cholecystectomy patients are mobilized at onset, peak or post peak of opioid (meperidine) action
Creators: name: Brazier, Linda Diane

description: There has been little study of ways to decrease pain generated by painful postoperative exercise. The purpose of this study was to determine the effect of performing painful activities at various times of analgesic action on pain sensation, pain distress and inspiratory capacity of one day postoperative cholecystectomy patients. In addition, the relationship of inspiratory capacity to pain sensation and distress was explored. The theoretical framework for this study was based on Melzack and Wall's Revised Gate Control Theory of Pain. This experimental study used a randomized balanced incomplete block design in which the subjects served as their own control. Subjects ranged in age from 25 to 59 years and were free of chronic disease, pain syndromes, chemical abuse and psychiatric disorders. Twelve subjects were randomly assigned to two out of three possible combinations: ambulation at 15, 60, or 110 minutes after receiving an intramuscular injection of meperidine. These times represented the predicted onset, peak and post peak of analgesic action. After ambulation, subjects scored a visual analogue scale measuring pain sensation and a rating scale measuring level of distress, and then performed 5 maximal inspirations using a Volurex incentive spirometer. An analysis of variance found no significant difference in pain sensation, distress or inspiratory capacity when subjects were ambulated at different times after meperidine injection. Overall, moderate but variable levels of pain sensation and distress were reported. Decreases in postoperative inspiratory capacity ranged from 40 to 90% of the preoperative baseline. The relationship between inspiratory capacity and pain sensation scores was non significant but a strong trend was noted. When the change in inspiratory capacity between two ambulation times was correlated with the change in pain sensation, a significant negative correlation was found. The relationship between inspiratory capacity and distress was non significant. Additional correlations were performed among selected variables related to sample characteristics. A negative correlation between age and pain sensation was the only significant ancillary finding. The findings were discussed in relation to theoretical expectations, other research studies, and methodological problems inherent in the study. Implications of the findings for nursing practice, education and theory were suggested. Recommendations for future research were made.

description: No abstracts are to be cited without prior reference to the author.Deep-water fishes have only recently moved from being objects of scientific curiosity to objects of commercial exploitation. For an increasing number of species, a single trawl today captures more specimens than science has ever seen since the time of Linnaeus. The deep-water habitats where fisheries are conducted, mostly continental slopes, are known to be physically and biologically more complex than the shallower shelves, yet thinking and experience from the shelf seems mostly to govern deep-water fishery expansion. Ecological considerations suggest that deep-water populations and ecosystems may be even more vulnerable to disruption than were those of the shelf. But the rate at which scientific study progresses lags well behind the rate at which deep-water fisheries develop. It often seems, in fact, that a fishery may be over before scientific study begins in earnest. Approaches to understanding based on theory and an holistic appreciation of how the deepwater world works can help, as cal) critical examination and mapping of a fishery' s history.

description: We study the propagation of gravitons within 5-D supersymmetric braneworld models with a bulk scalar field. The setup considered here consists of a 5-D bulk spacetime bounded by two 4-D branes localized at the fixed points of an $S^1/Z_2$ orbifold. There is a scalar field $ϕ$ in the bulk which, provided a superpotential $W(ϕ)$, determines the warped geometry of the 5-D spacetime. This type of scenario is common in string theory, where the bulk scalar field $ϕ$ is related to the volume of small compact extra dimensions. We show that, after the moduli are stabilized by supersymmetry breaking terms localized on the branes, the only relevant degrees of freedom in the bulk consist of a 5-D massive spectrum of gravitons. Then we analyze the gravitational interaction between massive bodies localized at the positive tension brane mediated by these bulk gravitons. It is shown that the Newtonian potential describing this interaction picks up a non-trivial contribution at short distances that depends on the shape of the superpotential $W(ϕ)$. We compute this contribution for dilatonic braneworld scenarios $W(ϕ) = e^{αϕ}$ (where $α$ is a constant) and discuss the particular case of 5-D Heterotic M-theory: It is argued that a specific footprint at micron scales could be observable in the near future.

description: No abstracts are to be cited without prior reference to the author.The Alaska Department of Fish and Grune (ADF&G) is using geophysical techniques to classify marine fish habitats for use in stock assessment of Demersal Shelf Rockfishes or DSR(Scorpaenidae: ,Sebastes). DSR are the target of an important shore.based fishery in the .eastern Gulf of Alaska (560 mt allowable catch). These fishes are difficult to assess using traditional techniques as they are closely associated with complex rocky habitats. We have been using an occupied submersible to conduct line transects for estimating density of DSR since 1990. Biomass is derived as the product of estimated density (for .all rocky habitats), the estimate. of area of suitable habitat within the 200 m contour, and average weight of fish from port samples by management,area. Currently the estimate of area of suitable habitatis based solely on the habitat description from U.S. NOAA National Ocean Service navigation/bathymetric charts -- seafloor•classification in these charts is very limited. To improve our.delineation of available habitat, we conducted. a series of sidescan sonar surveys to identify. areas· of key habitat. types in the area offshore of Kruzof Island, Alaska, an important fishing ground in the Central Southeast Outside (CSEO) management.area. The result is a Iarge mosaic encompassing 563 km2 of the seafloor off Kruzof Island, approximately one· fourth of the estimated· DSR habitat in CSEO.. The area is diverse· in habitat, including. areas of platonic rock outcrop, boulders, gravel or pebble, and sand, plus an extended area of lava flows. These habitat characterizations have been groundtruthed with • direct observations from a submersible.

description: The anomalous Hall effect is caused by magnetic textures such as skyrmions. We derive an analytical formula of the Hall conductivity on the surface of a topological insulator up to third order in magnetization, $\boldsymbol{M}(\boldsymbol{x})$, based on a perturbative approach. We identify the magnetic textures that contribute to the Hall conductivity up to third order in magnetization and second order in spatial differentiation. We treat magnetization as a perturbation to calculate the Hall conductivity for each magnetic texture based on the linear response theory. Furthermore, we estimate the skyrmion-induced Hall conductivity and confirm that it depends on the shape of skyrmions, such as Bloch-type or Néel-type skyrmions. The results of this study can be applied not only to conventional skyrmion systems but also to more general magnetic structures.

description: This is a poster presentation introducing the reader to the Climate Cooperative Initiatives Database (C-CID).

Cooperative climate initiatives (CCIs) are collaborative arrangements involving two or more actors, including at least one non-state actor (e.g. businesses, investors, or civil society organisations) or one subnational actor (e.g. municipalities or regional governments). CCIs aim to address climate mitigation and/or adaptation. Recent studies highlight the significant climate mitigation potential of these efforts, often exceeding the impact of individual commitments by non-state and subnational actors.Moreover, CCIs can contribute to adaptation, resilience building, and help advance Sustainable Development Goals (SDGs). The Climate Cooperative Initiatives Database (C-CID) aims to bolster integrity, accountability and trust among participants of CCIs by tracking progress and effectiveness, and identifying best practices.

description: Since neutrinos can escape from dense regions without being deflected, they are promising candidates to study the new physics at the sources that produce them. With the increasing development of more sensitive detectors in the coming years, we will infer several intrinsic properties from incident neutrinos. In particular, we centralise our study in those produced by thermal processes in short gamma-ray bursts (sGRBs) and their interactions within the central engine's anisotropic medium. On the one hand, we consider baryonic winds produced with a strong magnetic contribution, and on the other hand, we treat only neutrino-driven winds. First, we obtain the effective neutrino potential considering both baryonic density profiles around the central engine. Then, we get the three-flavour oscillation probabilities in this medium to finally calculate the expected neutrino ratios. We find a stronger angular dependence on the expected neutrino ratios, which, incidentally, contrast from the expected theoretical ratios without considering the winds' additional contribution. The joint analysis of this observable, together with the sGRB ejected jet angle, might lead to an effective mechanism to discriminate between the involved merger progenitors (black hole-neutron star or neutron star-neutron star), acting as an additional detection channel to gravitational waves.

description: The emerging field of ultracold molecules with their rich internal structure is currently attracting a lot of interest. Various methods have been developed to produce ultracold molecules in pre-set quantum states. For future experiments it will be important to efficiently transfer these molecules from their initial quantum state to other quantum states of interest. Optical Raman schemes are excellent tools for transfer, but can be involved in terms of equipment, laser stabilization and finding the right transitions. Here we demonstrate a very general and simple way for transfer of molecules from one quantum state to a neighboring quantum state with better than 99% efficiency. The scheme is based on Zeeman tuning the molecular state to avoided level crossings where radio-frequency transitions can then be carried out. By repeating this process at different crossings, molecules can be successively transported through a large manifold of quantum states. As an important spin-off of our experiments, we demonstrate a high-precision spectroscopy method for investigating level crossings.

description: In this paper, we investigate the fixed-time behavioral control problem for a team of second-order nonlinear agents, aiming to achieve a desired formation with collision/obstacle~avoidance. In the proposed approach, the two behaviors(tasks) for each agent are prioritized and integrated via the framework of the null-space-based behavioral projection, leading to a desired merged velocity that guarantees the fixed-time convergence of task errors. To track this desired velocity, we design a fixed-time sliding mode controller for each agent with state-independent adaptive gains, which provides a fixed-time convergence of the tracking error. The control scheme is implemented in a distributed manner, where each agent only acquires information from its neighbors in the network. Moreover, we adopt an online learning algorithm to improve the robustness of the closed system with respect to uncertainties/disturbances. Finally, simulation results are provided to show the effectiveness of the proposed approach.

description: We study localization properties of two-dimensional Dirac fermions subject to a power-law-correlated random vector potential describing, e.g., the effect of "ripples" in graphene. By using a variety of techniques (low-order perturbation theory, self-consistent Born approximation, replicas, and supersymmetry) we make a case for a possible complete localization of all the electronic states and compute the density of states.

description: No abstracts are to be cited without prior reference to the author.The data we present were collected from one trawl and three longline exploratory surveys and covering the depths between 400 and 2,000 meters. The majority of the information is from depths between 500 and 1,200 meters. Information on 56 species from 27 families is presented with regard to temperature, geographical distribution and depth. For some species, new information on geographical distribution is presented. In the northern part of the ridge (north of 52° N) sub arctic species such as Sebastes spp., tusk (Brosme brosme) and Greenland halibut (Reinhardtius hippoglossoides) are dominant. In the southern part (south of 48° N), sub tropical species such as golden eye pearch (Beryx splendens) and cardinal fish (Epigonus telescopus) are the dominant species. In the area between 48° N and 52° N there is a change in species composition. Some species seem to have their northernmost distribution, on the ridge, in this area, and others seems to have their southernmost distribution in this area. However some species such as orange roughy (Hoplostethus atlanticus), round nose grenadier (Coryphaenoides rupestris) and leafscale gulper shark (Centrophorus squamosus) are distributed in the whole area.

description: Volatility clustering is an important characteristic that has a significant effect on the behavior of stock markets. However, designing robust models for accurate prediction of future volatilities of stock prices is a very challenging research problem. We present several volatility models based on generalized autoregressive conditional heteroscedasticity (GARCH) framework for modeling the volatility of ten stocks listed in the national stock exchange (NSE) of India. The stocks are selected from the auto sector and the banking sector of the Indian economy, and they have a significant impact on the sectoral index of their respective sectors in the NSE. The historical stock price records from Jan 1, 2010, to Apr 30, 2021, are scraped from the Yahoo Finance website using the DataReader API of the Pandas module in the Python programming language. The GARCH modules are built and fine-tuned on the training data and then tested on the out-of-sample data to evaluate the performance of the models. The analysis of the results shows that asymmetric GARCH models yield more accurate forecasts on the future volatility of stocks.

An exploration of the experience of the patient with cancer pain
Creators: name: McIntyre, Marjorie Ruth
Publisher: name: University of British Columbia
Year: 2010

description: This study was designed to elicit the patient's perspective on the experience of cancer pain for the purpose of gaining knowledge that would enable health professionals to intervene more effectively with patients who experience cancer pain. Data were collected by means of in-depth interviews with 10 patients, ranging in age from 44 to 67, each of whom was a patient at an ambulatory pain clinic in Greater Vancouver. A set of questions generated from the literature and the researcher's experience guided the initial interviews. As the interviews progressed, additional questions were formulated from the data. Through a process of constant comparative analysis and validation of analytical data with participants, the researcher was able to construct accounts reflecting the participant's perspectives. An analytic framework was developed from the themes and concept categories in the data. According to the participants in this study, the experience of cancer pain included the pain, the impact of the pain on their well-being, and the strategies they utilized to cope both with the pain and its impact. Participants explained the impact of cancer pain within the context of the coping strategies they employed. Although participants in the study interpreted and managed their pain in very individual ways, common concerns were identified in the experience that have implications for nursing practice and research.

description: Using spin-polarized low-energy electron microscopy to study magnetization in epitaxial layered systems, we found that the area vs perimeter relationship of magnetic domains in the top Fe layers of Fe/NiO/Fe(100) structures follows a power-law distribution, with very small magnetic domain cutoff radius (about 40 nm) and domain wall thickness. This unusual magnetic microstructure can be understood as resulting from the competition between antiferromagnetic and ferromagnetic exchange interactions at the Fe/NiO interfaces, rather than from mechanisms involving the anisotropy and dipolar forces that govern length scales in conventional magnetic domain structures. Statistical analysis of our measurements validates a micromagnetic model that accounts for this interfacial exchange coupling.

description: No abstracts are to be cited without prior reference to the author.Centrophoms squamosus is one of the target species of the deepwater fishery in the Northeast Atlantic. There is no published information on age for this species. The second dorsal spines of C. squamosus were used to produce age estimates. Samples were collected by trawl and longline surveys (1995-1997) and from landings (1997- 1998). Marks were observed on the spine ofCentrophonis squamosus in two separate regions; in the dentine, in cross-sections, and on the mantle. Initial age estimates ranged from 9-3 5 years. A distinct mark, observed on the distal portion of the stem of C. squamosus may be associated with parturition. There is an absence of smaller. individuals from the sample. Centra of these species were difficult to section and did not display any banding pattern after staining. The initial age studies, though not validated, indicate slow rates of growth. Length frequencies based on the aged sample show a marked absence of specimens below 82 cm
