Significance of Virtual Backbone In Wireless Ad-Hoc Network (2013)

Abstract:- This paper based on research related Ad hoc networks does not rely on dedicated network devices. It relay or route messages f rom a source to a destination. As there is no global coordinator, nodes have to organize themselves to avoid scalability issues that may arise when the size of the network is growing. Virtual backbones, by selecting a subset of network nodes and / or communication channels, ar e a set of techniques mimicking the infrastructure in the classical network paradigm. Ad hoc virtual backbones however are not composed of dedicated devices but from regular network nodes which were selected to help relaying messages. The connected dominating s et (CDS) has been extensively used for routing and broadcast in wireless ad hoc networks. While existing CDS protocols are successful in constr ucting CDS of small size, they either require localized information beyond immediate neighbours, lack the mechanism to properly handle nodal mobility, or involve lengthy recovery procedure when CDS becomes corrupted.

An Engineering-consistent Bayesian Scheme for 4D Seismic to Simulator Inversion (2015)

Summary A workflow is designed to integrate simulator to seismic predictions into the process of 4D seismic inversion using a coupled Bayesian scheme, and honouring the concept of reservoir engineering consistency (EC). The proposed approach is demonstrated by an application to a West Africa dataset. The results show the benefits of being EC when working across domains during a “close the loop” exercise.
Advanced time domain method for remote wind farms with LFAC transmission systems: Power transfer and harmonics (2012)

This paper presents an advanced time domain model for systems of remote wind farms connected to the power grid via low frequency AC transmission (LFAC). This system contains standard converters as well as cyclo-converters. The time domain model is based on the quadratic integration method. Specifically, the method consist of two steps: (a) quadratization of the models of the constituent parts of the system, and (b) quadratic integration of the quadratic models. The proposed time domain models by the application of the quadratic integration have been demonstrated to be accurate, robust, and reliable as compared to those by the application of other integration methods such as the trapezoidal integration. The goal of this paper is to present this time domain method and the performance of wind farms connected to the power grid via LFAC transmission. Several examples of wind farms with LFAC transmission systems interconnected by a phase-controlled three-phase cycloconverter are presented.
Development, Regeneration and Plasticity of the Autonomic Nervous System (2024)

For many years the idea of antagonistic parasympathetic, cholinergic and sympathetic adrenergic control of most organs in visceral and cardiovascular systems formed the working basis for most studies. However, major advances since the 1960s have made it necessary to revise the thinking about mechanisms of autonomic transmission. These advances have significant implications for our understanding of diseases involving the autonomic nervous system and their treatment. In broad terms, these concepts shift the earlier emphasis on central control mechanisms towards greater consideration of the sophisticated local peripheral control mechanisms. Volume one of this series deals with the basic mechanisms of neuroeffector transmission which sets the stage for later volumes devoted to the autonomic nervous control of particular organ systems. Other volumes deal with the central nervous control of autonomic function, interaction of autonomic mechanisms with the endocrine system, development, regeneration and plasticity of the autonomic nervous system and comparative physiology and evolution. This second volume in the series deals with nervous control of the urogenital system. Coverage includes the neural control of renal function, neural regulation of ureteric mobility, synaptic transmission of pelvic ganglia, neural control of penile erection and pain arising from the urogenital tract.
Mitotic Regulation of Microtubule Cross-Linking Activity of CENP-E Kinetochore Protein (1994)

CENP-E is a kinesin-like protein that is transiently bound to kinetochores during early mitosis, becomes redistributed to the spindle midzone at anaphase, and is degraded after cytokinesis. At anaphase, CENP-E may cross-link the interdigitating microtubules in the spindle midzone through a motor-like binding site at the amino terminus and a 99-amino acid carboxyl-terminal domain that bound microtubules in a distinct manner. Phosphorylation of the carboxyl terminus by the mitotic kinase maturation promoting factor (MPF) inhibited microtubule-binding activity before anaphase. Thus, MPF suppresses the microtubule cross-linking activity of CENP-E until anaphase, when its activity is lost.
Inhibition of coupling factor B activity by cadmium ion, arsenite-2,3-dimercaptopropanol, and phenylarsine oxide, and preferential reactivation by dithiols. (1981)

Coupling factor B activity was measured by the stimulation of the ATP-driven NAD+ reduction by succinate or the 32Pi-ATP exchange activity of Factor B-depleted submitochondrial particles. Half-maximal coupling activity was inhibited by 30 microM cadmium, 5 microM phenylarsine oxide, or 0.3 mM arsenite-2,3-dimercaptopropanol. The inhibition was relieved by slight excess of dithiol but not by a 10-fold molar excess of 2-mercaptoethanol. Inhibition of coupling activity by phenylarsine oxide or cadmium was not due to interference in binding of Factor B to depleted particles. Isolated Factor B binds phenylarsine oxide resulting in loss of ability to stimulate depleted submitochondrial particles. The inhibition was largely overcome by dithiol but not by monothiols. The residual coupling activity of depleted submitochondrial particles was highly resistant to cadmium or arsenical. Moreover, binding of arsenical to the depleted particles per se, did not result in inhibition of Factor B-stimulated activity. Furthermore, the addition of phenylarsine oxide to H+-ATPase resulted in loss of Pi-ATP exchange and stimulation of oligomycin-sensitive ATPase activities. Both effects were further potentiated by 2-mercaptoethanol and reversed by dithiols. These effects parallel uncoupling of oxidative phosphorylation in mitochondria by these inhibitors and point to Factor B as the probable component sensitive to these inhibitors.
A “Melanopic” Spectral Efficiency Function Predicts the Sensitivity of Melanopsin Photoreceptors to Polychromatic Lights (2011)

Photoreception in the mammalian retina is not restricted to rods and cones but extends to a small number of intrinsically photosensitive retinal ganglion cells expressing the photopigment melanopsin. These mRGCs are especially important contributors to circadian entrainment, the pupil light reflex, and other so-called nonimage-forming (NIF) responses. The spectral sensitivity of melanopsin phototransduction has been addressed in several species by comparing responses to a range of monochromatic stimuli. The resultant action spectra match the predicted profile of an opsin:vitamin A-based photopigment (nomogram) with a peak sensitivity (λ(max)) around 480 nm. It would be most useful to be able to use this spectral sensitivity function to predict melanopsin's sensitivity to broad-spectrum, including "white," lights. However, evidence that melanopsin is a bistable pigment with an intrinsic light-dependent bleach recovery mechanism raises the possibility of a more complex relationship between spectral quality and photoreceptor response. Here, we set out to empirically determine whether simply weighting optical power at each wavelength according to the 480-nm nomogram and integrating across the spectrum could predict melanopsin sensitivity to a variety of polychromatic stimuli. We show that pupillomotor and circadian responses of mice relying solely on melanopsin for their photosensitivity (rd/rd cl) can indeed be accurately predicted using this methodology. Our data therefore suggest that the 480-nm nomogram may be employed as the basis for a new photometric measure of light intensity (which we term "melanopic") relevant for melanopsin photoreception. They further show that measuring light in these terms predicts the melanopsin response to light of divergent spectral composition much more reliably than other methods for quantifying irradiance or illuminance currently in widespread use.
Genus- and species-specific identification of mycoplasmas by 16S rRNA amplification (1992)

Systematic computer alignment of mycoplasmal 16S rRNA sequences allowed the identification of variable regions with both genus- and species-specific sequences. Species-specific sequences of Mycoplasma collis were elucidated by asymmetric amplification and dideoxynucleotide sequencing of variable regions, using primers complementary to conserved regions of 16S rRNA. Primers selected for Mycoplasma pneumoniae, M. hominis, M. fermentans, Ureaplasma urealyticum, M. pulmonis, M. arthritidis, M. neurolyticum, M. muris, and M. collis proved to be species specific in the polymerase chain reaction. The genus-specific primers reacted with all mycoplasmal species investigated as well as with members of the genera Ureaplasma, Spiroplasma, and Acholeplasma. No cross-reaction was observed with members of the closely related genera Streptococcus, Lactobacillus, Bacillus, and Clostridium or with any other microorganism tested. On the basis of the high copy number of rRNA, a highly sensitive polymerase chain reaction assay was developed in which the nucleic acid content equivalent to a single organism could be detected.
Determination of Budding Success of Loquats Budded in the Open and in A Heated Greenhouse (1996)

This budding experiment was carried out in Adana during l99l-92 on the loquat seedlings grown in the open and in a heated greenhouse. The bud sticks of Gold Nugget cv. were used. The buddings (T, chip and patch) were done on the l5th of December, l5th of January and l5th of February. The success rate of buddings was 85.55 % in the greenhouse and 67.72 % in the open air.
Tomato immune receptor Ve1 recognizes effector of multiple fungal pathogens uncovered by genome and RNA sequencing (2012)

Fungal plant pathogens secrete effector molecules to establish disease on their hosts, and plants in turn use immune receptors to try to intercept these effectors. The tomato immune receptor Ve1 governs resistance to race 1 strains of the soil-borne vascular wilt fungi Verticillium dahliae and Verticillium albo-atrum, but the corresponding Verticillium effector remained unknown thus far. By high-throughput population genome sequencing, a single 50-Kb sequence stretch was identified that only occurs in race 1 strains, and subsequent transcriptome sequencing of Verticillium-infected Nicotiana benthamiana plants revealed only a single highly expressed ORF in this region, designated Ave1 (for Avirulence on Ve1 tomato). Functional analyses confirmed that Ave1 activates Ve1-mediated resistance and demonstrated that Ave1 markedly contributes to fungal virulence, not only on tomato but also on Arabidopsis. Interestingly, Ave1 is homologous to a widespread family of plant natriuretic peptides. Besides plants, homologous proteins were only found in the bacterial plant pathogen Xanthomonas axonopodis and the plant pathogenic fungi Colletotrichum higginsianum, Cercospora beticola, and Fusarium oxysporum f. sp. lycopersici. The distribution of Ave1 homologs, coincident with the presence of Ave1 within a flexible genomic region, strongly suggests that Verticillium acquired Ave1 from plants through horizontal gene transfer. Remarkably, by transient expression we show that also the Ave1 homologs from F. oxysporum and C. beticola can activate Ve1-mediated resistance. In line with this observation, Ve1 was found to mediate resistance toward F. oxysporum in tomato, showing that this immune receptor is involved in resistance against multiple fungal pathogens.
Injectable testosterone undecanoate has more favourable pharmacokinetics and pharmacodynamics than testosterone enanthate (1995)

Testosterone preparations producing constant physiological testosterone serum levels are desirable for long-term treatment of androgen deficiency. However, all injectable testosterone esters used clinically for substitution of male hypogonadism are characterized by unfavourable pharmacokinetics. We therefore tested two groups of five long-term orchidectomized cynomolgus monkeys (Macaca fascicularis), which received a single intramuscular injection of 10 mg/kg body weight of an injectable testosterone undecanoate (TU) preparation or testosterone enanthate (TE) in a preclinical study to assess the pharmacokinetic and pharmacodynamic characteristics of TU in comparison to TE. The dose was equivalent to 6.3 and 7.2 mg of pure testosterone per kilogram body weight in the TU and TE group, respectively. Following injection of TU, mean serum testosterone rose to 58 +/- 18 nmol/l on day 1 and remained at moderately supraphysiological levels of 40-68 nmol/l for 45 days. Thereafter, testosterone levels were maintained in the normal range of intact monkeys for another 56 days. The TE injection resulted in highly supraphysiological levels of 100-177 nmol/l from immediately after the injection to day 5. A rapid decline followed and testosterone levels reached the lower limit of normal after 31 days. Serum testosterone levels were significantly higher in the TE-than in the TU-treated animals on days 0.5-7 (p < 0.05). Significantly lower testosterone levels were seen in the TE than in the TU group on days 16, 22, 25 and 31 (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
Replication and Caching Strategies in Cadmium (1998)

The Cadmium project aims at providing system support for disconnected and mobile users. This includes basic mechanisms for ensuring data availability, such as replication, caching or prefetching, as well as additional ones for consistency, adaptation to environment changes, etc. In order to insure good tradeoffs when degrading a service while disconnected, we provide resource-awareness and hooks for application or user-level interaction, along with automatic system support.
Bioreactor cultivation of osteochondral grafts (2005)

The clinical utility of tissue engineering depends upon our ability to direct cells to form tissues with characteristic structural and mechanical properties across different hierarchical scales. Ideally, an engineered graft should be tailored to (re)establish the structure and function of the native tissue being replaced. Engineered grafts of such high fidelity would also foster fundamental research by serving as physiologically relevant models for quantitative in vitro studies. The approach discussed here involves the use of human mesenchymal stem cells (hMSC) cultured on custom-designed scaffolds (providing a structural and logistic template for tissue development) in bioreactors (providing environmental control, biochemical and mechanical cues). Cartilage, bone and ligaments have been engineered by using hMSC, highly porous protein scaffolds (collagen; silk) and bioreactors (perfused cartridges with or without mechanical loading). In each case, the scaffold and bioreactor were designed to recapitulate some aspects of the environment present in native tissues. Medium flow facilitated mass transport to the cells and thereby enhanced the formation of all three tissues. In the case of cartilage, dynamic laminar flow patterns were advantageous as compared to either turbulent steady flow or static (no flow) cultures. In the case of bone, medium flow affected the geometry, distribution and orientation of the forming bone-like trabeculae. In the case of ligament, applied mechanical loading (a combination of dynamic stretch and torsion) markedly enhanced cell differentiation, alignment and functional assembly. Taken together, these studies provide a basis for the ongoing work on engineering osreochondral grafts for a variety of potential applications, including those in the craniofacial complex.
Reconstruction of algorithms from memory snapshots of their execution (1976)

A system is described which utilizes a trace of memory snapshots taken during the execution of an algorithm. With such traces and a description of the environment in which the algorithm was executed, the algorithm can be reconstructed. In the first phase, decomputation of the results which appear in the snapshots is performed. Decomputation is the process which produces, for each result in the trace, the set of possible instructions which could have been its cause. The construction phase then uses static and dynamic information obtained from the trace to aid in synthesizing the algorithm. A number of experiments which have been performed with system are also described.
Geometries and materials for subwavelength surface plasmon modes (2004)

Plasmonic waveguides can guide light along metal-dielectric interfaces with propagating wave vectors of greater magnitude than are available in free space and hence with propagating wavelengths shorter than those in vacuum. This is a necessary, rather than sufficient, condition for subwavelength confinement of the optical mode. By use of the reflection pole method, the two-dimensional modal solutions for single planar waveguides as well as adjacent waveguide systems are solved. We demonstrate that, to achieve subwavelength pitches, a metal-insulator-metal geometry is required with higher confinement factors and smaller spatial extent than conventional insulator-metal-insulator structures. The resulting trade-off between propagation and confinement for surface plasmons is discussed, and optimization by materials selection is described.
Management of non-alcoholic fatty liver disease in 2015 (2015)

There is no single pharmacologic therapy that has been approved to treat nonalcoholic fatty liver disease in the general population. The backbone of therapy currently includes intensive lifestyle modification with established targets for diet and weight loss. The use of unsweetened, unfiltered coffee along with limiting high fructose corn syrup have emerged as beneficial dietary recommendations. The use of empiric oral hypoglycemic agents and vitamin E, however, has not been widely accepted. Developing bariatric surgical techniques are promising, but additional studies with long-term follow up are needed before it can be widely recommended. Finally, liver transplantation is an increasingly frequent consideration once complications of end-stage disease have developed. The future treatment of those with nonalcoholic fatty liver disease will likely involve a personalized approach. The importance of the gut microbiome in mediating hepatocyte inflammation and intestinal permeability is emerging and may offer avenues for novel treatment. The study of anti-fibrotic agents such as pentoxifylline and FXR agonists hold promise and new pathways, such as hepatocyte cannabinoid receptor antagonists are being studied. With the incidence of obesity and the metabolic syndrome increasing throughout the developed world, the future will continue to focus on finding novel agents and new applications of existing therapies to help prevent and to mediate the progression of nonalcoholic fatty liver disease.
Analysis of Bubble Chamber Data (1963)

On the Mapping Problem (1981)

In array processors it is important to map problem modules onto processors such that modules that communicate with each other lie, as far as possible, on adjacent processors. This mapping problem is formulated in graph theoretic terms and shown to be equivalent, in its most general form, to the graph isomorphism problem. The problem is also very similar to the bandwidth reduction problem for sparse matrices and to the quadratic assignment problem.
Adaptive deadlock-free worm-hole routing in hypercubes (2003)

Two new algorithms for worm-hole routing in the hypercube are presented. The first hypercube algorithm is adaptive, but non-minimal in the sense that some derouting is permitted. Then another deadlock-free adaptive worm-hole based routing algorithm for the hypercube interconnection is presented which is minimal. Finally some well-known worm-hole algorithms for the hypercube were evaluated together with the new ones on a hypercube of 2/sup 10/ nodes. One oblivious algorithm, the Dimension-Order, or E-Cube routing algorithm (W. Dally, C. Seitz, 1987) was tried. In addition, three partially adaptive algorithms were considered: the Hanging algorithm (Y. Birk, P. Gibbons, D. Soroker, J. Sanz, 1989 and S. Konstantinidou, 1990), the Zenith algorithm (S. Konstantinidou, 1990), and the Hanging-Order algorithm (G.-M. Chia, S. Chalasani, C.S. Raghavendra, 1991). Finally, a fully adaptive minimal algorithm presented independently by L. Gravano, G. Pifarre, S.A. Felperin and J. Sanz (1991) and J. Duato was tried. This algorithm allows each message to choose adaptively among all the shortest paths from its source to its destination. Only four virtual channels per physical link are needed to achieve this. This technique is referred to as Fully. The results obtained show that the two new algorithms are good candidates as a choice for worm-hole routing in the hypercube network.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Contribution of Broadcasting (1982)

Abstract The contribution that broadcasting can make to a programme for survival is seen as a product of what problems can be identified as causing a threat to survival. The strengths and weaknesses of broadcasting are then examined in order to establish realistic expectations as to what broadcasting can do. Four key roles for broadcasting are then identified alongside the conditions for their successful implementation.
The Application of Job Rotation in End User Computing (1997)

This paper applies the management literature on job rotation to current issues in end user computing (EUC). Perceived benefits of job rotation include: transfer of knowledge across organizational functions; reduced conflict across departments; organizational integration; creation of a climate conducive to innovation; and, challenging and maturing opportunities for employees. Job rotation between end user areas and EUC support staff is therefore proposed to yield the following benefits: increased knowledge and skill sets for end users and end user computing support; reduced communication gap between IS and users; improved organizational integration of end user computing; effective utilization of end user computing; and, more flexible staffing and career paths for end user computing support personnel. The resulting model for the implementation of job rotation between end user areas and EUC support staff includes five critical success factors. In addition to providing a foundation for research in this area, the model provides guidance for organizations seeking to implement such rotations.Request access from your librarian to read this article's full text.
