Rossby waves and zonons in zonostrophic turbulence

Two-dimensional, small-scale forced turbulent flows on the surface of a rotating sphere, along with the familiar Rossby-Haurwitz waves, reveal a new class of waves termed zonons. The zonons form non-dispersive wave packets that propagate in the westward direction with the velocity equal to the phase speed of the most energetic Rossby-Haurwitz wave. Zonons preserve their identity even after the forcing is switched off and the flow undergoes structural reorganization. Zonons reside in locations with the maximum meridional shear and are engaged in strong energy exchange with themean flow. These physical properties of zonons point to their identitywith Rossby solitary waves. The symbiosis between themean flow and the solitarywaves plays an important role in the large-scale dynamics.
4 Performance Profile : Why we focused on the SVD

Principal Component Analysis (PCA; Pearson, 1901) is a widely used method for data compression. The goal is to find the best low rank approximation of a given matrix, as judged by minimization of the `2 norm of the difference between the original matrix and the low rank approximation. However, the classical method is not resistant to corruption of individual input data points. Recently, a robust form of PCA has been proposed, in which a matrix M is decomposed as the sum of a low rank component L0 and a sparse component S0 (Candés et al., 2009):
NUMERICAL COMPUTATIONS IN SCHUBERT CALCULUS

Traditional formulations of geometric problems from the Schubert calculus, either in Plücker coordinates or in local coordinates provided by Schubert cells, yield systems of polynomials that are typically far from complete intersections and (in local coordinates) typically of degree exceeding two. We present an alternative primal-dual formulation using parametrizations of Schubert cells in the dual Grassmannians in which intersections of Schubert varieties become complete intersections of bilinear equations. This formulation enables the numerical certification of problems in the Schubert calculus.

An Analysis of Basic Structures for Effective Computation in Single Electron Tunneling Technology

Single Electron Tunneling (SET) technology appears to be a promising alternative for CMOS as it exhibits excellent power consumption and scalability features. Moreover, this new technology opens up avenues for new computational paradigms, which require building blocks with unconventional behavior. In this paper we discuss a number of basic building blocks that allow for effective implementations of computational structures in those new paradigms, and analyze them in terms of area, delay, and energy consumption.
Development of resistance in Tribolium castaneum, Herbst (Coleoptera: Tenebrionidae) towards deltamethrin in laboratory

A strain of Tribolium castaneum (Herbst) was developed for resistance against deltamethrin, after six generation of selection from a laboratory susceptible strain, through topical application method. The selection was initiated at the dose 0.0004, which was increased during successive generations' upto 0.026 in sixth generation. The resistance ratio of selected strain was determined, and it was found to be 370.5 fold in sixth generation as compared to susceptible strain.
Pso2 (SNM1) is a DNA structure-specific endonuclease

Many types of DNA structures are generated in response to DNA damage, repair and recombination that require processing via specialized nucleases. DNA hairpins represent one such class of structures formed during V(D)J recombination, palindrome extrusion, DNA transposition and some types of double-strand breaks. Here we present biochemical and genetic evidence to suggest that Pso2 is a robust DNA hairpin opening nuclease in budding yeast. Pso2 (SNM1A in mammals) belongs to a small group of proteins thought to function predominantly during interstrand crosslink (ICL) repair. In this study, we characterized the nuclease activity of Pso2 toward a variety of DNA substrates. Unexpectedly, Pso2 was found to be an efficient, structure-specific DNA hairpin opening endonuclease. This activity was further shown to be required in vivo for repair of chromosomal breaks harboring closed hairpin ends. These findings provide the first evidence that Pso2 may function outside ICL repair and open the possibility that Pso2 may function at least in part during ICL repair by processing DNA intermediates including DNA hairpins or hairpin-like structures.
A composition technique of multiple switching functions based on BDD

Binary Decision Diagram has a great impact on the Boolean function manipulation for its compressed and canonical presentation. In switching function organization ROBDD (Reduced Ordered Binary Decision Diagram) with a fixed variable ordering plays a significant role for its distinctiveness. Combination of multiple functions using switching operations has more redundant states. For removing these redundant states we apply ROBDD in this joining process. In this paper, we presented the way of combining n number of functions using ROBDD with a fixed variable ordering. In our proposed method at first, we compute each function's ROBDD over Shannon's expression. Then switching operations are going to be performed over these functions and ROBDD of the combinations of these functions are also computed. By this method, appearance of redundant states will be less. To construct an understandable and simple method, some examples have been used.
Chromosome Damage Caused by Accidental Chronic Whole-Body Gamma Radiation Exposure in Thailand

In February 2000, a radiation incident involving a medical 60Co source occurred in a metal scrapyard in Thailand. Several individuals were suspected to have received chronic or fractionated exposures ranging from a few mGy to a several Gy. Using fluorescence in situ hybridization to paint chromosomes, we determined the frequencies of chromosome aberrations in peripheral blood lymphocytes of 13 people who entered the scrapyard, 3 people who involved in recovering the source, and 9 nearby residents. Aberration frequencies greater than controls were observed in 13 of the donors at 3 months postexposure. The predominant form of aberration observed was simple, complete, symmetrical translocations. An approximate 50% decrease in these aberrations and in total color junctions was observed in 7 donors resampled at 16 months postexposure. Although high, acute exposures are known to have detrimental effects, the biological consequences of chronic, low dose-rate radiation exposures are unclear. Thirteen of the donors had elevated aberration frequencies, and 6 also had symptoms of acute radiation syndrome. If there are any long-term health consequences of this incident, it will most likely occur among this group of individuals. The consequences for the remaining donors, who presumably received lower total doses delivered at lower dose rates, are less clear.
DECIDUOUS: decentralized source identification for network-based intrusions

DECIDUOUS is a security management framework for identifying the sources of network-based intrusions. The first key concept in DECIDUOUS is dynamic security associations, which efficiently and collectively provide location information for attack sources. DECIDUOUS is built on top of the IETF's IPSEC/ISAKMP infrastructure, and it does not introduce any new network protocol for source identification in a single administrative domain. It defines a collaborative protocol for inter-domain attack source identification. The second key concept in DECIDUOUS is the management information integration of the intrusion detection system (IDS) and attack source identification system (ASIS) across different protocol layers. For example, in DECIDUOUS, it is possible for a network-layer security control protocol (e.g., IPSEC) to collaborate with an application-layer intrusion detection system module (e.g., IDS for the SNMP engine). In this paper, we present the motivations, design, and prototype implementation of the DECIDUOUS framework.
Experiences from an implementation project - time management and control in home care

This paper is about the first trials during the implementation of a palm-based computer system in home care. The implementation project was carried out for several reasons. There was a need to gather information about the service calls. The palm-based system makes it also possible for the workers to utilize the information of the client database during service calls. Being assisted by a palm-based system is believed to raise the level of efficiency in home care and ease the process of growing professionalism amongst the workers. The study was carried out as a qualitative ethnographic study during the pilot phase of the implementation. First reactions of the care workers taking part in the trial period were more or less negative. The general attitude of the care workers was that the new system was implemented in order to place their work under the lens of surveillance. On the other hand, some of the workers felt that the new system enabled them to have more control of their working schedules and of carrying out different care tasks during a work day. Actual effects of the implementation and the possible changes in work practices can be seen only after a longer study.
Beta Blockade Protection of Bone Marrow Following Injury: A Critical Link between Heart Rate and Immunomodulation

Introduction Severe trauma induces a profound elevation of catecholamines that is associated with bone marrow (BM) hematopoietic progenitor cell (HPC) colony growth suppression, excessive BM HPC mobilization, and a persistent anemia. Previously, propranolol (BB) use after injury and shock has been shown to prevent this BM dysfunction and improve hemoglobin levels. This study seeks to further investigate the optimal therapeutic dose and timing of BB administration following injury and shock. Methods Male Sprague-Dawley rats were subjected to a combined lung contusion (LC), hemorrhagic shock (HS) model ± BB. In our dose response experiments, animals received BB at 1, 2.5, 5, or 10 mg/kg immediately following resuscitation. In our therapeutic window experiments, following LCHS rats were given BB immediately, 1 hour, or 3 hours following resuscitation. BM and peripheral blood (PB) were collected in all animals to measure cellularity, BM HPC growth, circulating HPCs, and plasma G-CSF levels. Results Propranolol at 5 and 10 mg/kg significantly reduced HPC mobilization, restored BM cellularity and BM HPC growth, and decreased plasma G-CSF levels. Propranolol at 5 and 10 mg/kg also significantly decreased heart rate. When BB was administered beyond 1 hour after LCHS, its protective effects on cellularity, BM HPC growth, HPC mobilization, and plasma G-CSF levels were greatly diminished. Conclusion Early Buse following injury and shock at a dose of at least 5mg/kg is required to maintain BM cellularity and HPC growth, prevent HPC mobilization, and reduce plasma G-CSF levels. This suggests that propranolol exerts its BM protective effect in a dose and time dependent fashion in a rodent model. Finally, heart rate may be a valuable clinical marker to assess effective dosing of propranolol.
The Riskier the Assets, the Riskier the Portfolios: Pitfalls and Misinterpretations

As the dependence structure (i.e. the copula) among the assets is fixed, one might think that the riskier the assets, the riskier the portfolio. Surprisingly enough, this conjecture turns out to be false even for coherent risk measures and normal returns. We show that two conditions are able to preserve risk ordering under the portfolio: Convexity for the risk measure and conditional increasingness for the copula. Eventually, conditional increasingness is checked for the most popular families of copulas used in financial modelling and actuarial sciences.
Salient Object Contour Detection Based on Boundary Similar Region

Salient object contours are important cues for object detection and shape recognition in computer vision. We propose a novel contour detection method for salient object considering salient edges operator. The method traces continuous boundaries from salient edges, computes similar regions between boundaries with direction channel and distance by Boundary Similar Region (BSR) algorithm. Then we fill the boundary similar regions by linear interpolation method to ensure that boundaries belong to a same contour. We demonstrate our method applied to salient object segmentation. Experiments indicate that our method show better accuracy of salient object boundary. On the basis of edge manipulation, our method is compact and simple that performs efficiently.
Rationalization in the Nigerian Public Service: Implications for Cross River State Workers Morale and Productivity

Rationalization in the Nigerian Public Service is a policy of government to purge the system of workers whose productivity is below expectations. Thus, it is a structural reform strategy for the interest of executing government's policy. Such policy rather than improving the productivity drive of the public service has resulted in the lack of commitment as far as workers' morale and productivity are concerned. This study therefore assessed the effect of rationalization in the Nigerian Public Service using Cross River State Civil service as a case study. Data generated for the study were sourced from 308 public servants from selected ministries and parastatals in the Cross River State Civil Service using structured questionnaire. Descriptive and inferential statistics were used in the analysis and presentation of data. Results showed that rationalization in public service significantly and negatively correlated with workers' productivity drive (r = -0.54; r critical = 0.11; P Key Words: Rationalization, Policy, Workers' Morale, Productivity, Public Service
A modified method for inducing periodontitis in dogs using a silk-wire twisted ligature

This study was designed to assess the effectiveness of a modified silk ligature twisted with wire for inducing advanced periodontitis. Periodontitis was induced in five premolars and one molar of 20 healthy dogs over a 60-day period. The dogs were divided into four groups according to the ligature-inducing materials used: soft moistened food only, wire ligature (WL), silk ligature (SL) and twisted ligature with silk and wire (SWL). Periodontal indices were recorded, and dental radiographs were taken before and after 60 days of ligation. The ligatures were checked daily and the day the ligature fell out was noted. The period during which the ligatures were maintained was significantly shorter for the SL group compared to the SWL group (p < 0.05). Results of the clinical examination showed that almost all periodontal status parameters including the plaque index, gingival index, clinical attachment level, and bleeding on probing were significantly exacerbated in the SWL group compared to the other groups (p < 0.05). Radiographic evaluation demonstrated that alveolar bone levels were significantly lower in the SWL group than the other groups on day 60 (p < 0.05). These results suggested that experimental periodontitis induced by SWL could be an effective method for investigating periodontitis in canine models.

Asymmetry in the link between the yield spread and industrial production: threshold effects and forecasting

We analyze the nonlinear behavior of the information content in the spread for future real economic activity. The spread linearly predicts one year ahead real growth in nine industrial production sectors of the US and four of the UK over the last forty years. However, recent investigations on the spread-real activity relation have questioned both its linear nature and its time-invariant framework. Our, in-sample, empirical evidence suggests that the spread real activity relationship exhibits asymmetries that allow for different predictive power of the spread when past spread values were above or below some threshold value. We then measure the out-of-sample forecast performance of the nonlinear model using predictive accuracy tests. The results show that significant improvement in forecasting accuracy, at least for one-step ahead forecasts, can be obtained over the linear model.
Comprehensive framework for tracking control and thrust allocation for a highly overactuated autonomous surface vessel

In this paper, we present a comprehensive trajectory tracking framework for cooperative manipulation scenarios involving marine surface ships. Our experimental platform is a small boat equipped with six thrusters, but the technique presented here can be applied to a multiship manipulation scenario such as a group of autonomous tugboats transporting a disabled ship or unactuated barge. The primary challenges of this undertaking are as follows: (1) the actuators are unidirectional and experience saturation; (2) the hydrodynamics of the system are difficult to characterize; and (3) obtaining acceptable performance under field conditions (i.e., global positioning system errors, wind, waves, etc.) is arduous. To address these issues, we present a framework that includes trajectory generation, tracking control, and force allocation that, despite actuator limitations, results in asymptotically convergent trajectory tracking. In addition, the controller employs an adaptive feedback law to compensate for unknown—difficult to measure—hydrodynamic parameters. Field trials are conducted utilizing a 3‐m vessel in a nearby estuary. © 2010 Wiley Periodicals, Inc. * This article is a US Government work and, as such, is in the public domain of the United States of America.
Altered brain white matter integrity in healthy carriers of the APOE ε4 allele

Background: Previous research has shown that polymorphisms of apolipoprotein E (APOE) represent genetic risk factors for dementia and for cognitive impairment in the elderly. The neural mechanisms by which these genetic variations influence behavioral performance or clinical severity are not well understood. Methods: The authors used diffusion tensor imaging to investigate ultrastructural properties in brain white matter to detect pathologic processes that modify tissue integrity. Sixty participants were included in the study of which 30 were homozygous for the APOE ε3 allele, 10 were homozygous for the APOE ε4 allele, and 20 had the APOE ε34 allele combination. All individuals were non-demented, and the groups were matched on demographic variables and cognitive performance. Results: The results showed a decline in fractional anisotropy, a marker for white matter integrity, in the posterior corpus callosum of ε4 carriers compared to non-carriers. Additional sites of altered white matter integrity included the medial temporal lobe. Conclusions: Although the mechanism underlying vulnerability of white matter tracts in APOE ε4 carriers is still unknown, these findings suggest that increased genetic risk for developing Alzheimer disease is associated with changes in microscopic white matter integrity well before the onset of dementia.
Emotional Sensibility and Behavioural Control of Real-Time Robotic Agents

Recent research in emotional systems has identified the important role of emotions in the control and the organisation of the behaviour of robotic systems. RTEA is a real-time emotional architecture for robotic agents. Emotions in RTEA modulate the thoughts' motivation that affect the final agent's behaviour. An emotional state is reached from the appraisal of a situation of the environment. The way this appraisal contributes to the emotional state and how this state affects the behaviour depends on the emotional sensibility. This paper focuses in the adjustment of the sensibility of the agent. A key point in the process of situation appraisal is the configuration of the contribution functions (CF). An adaptation of a multivariable optimisation method to find the optimal CF that affect the modulation of the emotion level and hence the robot anima, is proposed. Experiments on mobile robotics show that the adjustment of the emotional sensibility produces stable and predictable behavioural control.
