HRPMA: A Hybrid Routing Protocol Based on Mobile Agent for Wireless Ad Hoc Networks (2009)

This paper presents a hybrid routing protocol based on Mobile Agent (HRPMA) for Ad Hoc Networks (MANET). In the proposed approach, a few mobile agents move in the network and communicate with each node. They collect the network information to build the global information matrix of nodes. The data packets are transferred according to the matrix by a routing search algorithm. We have done the experiments in simulated environment of NS-2 system. This approach needs fewer moving agents to get more global information; therefore it reduces the overhead and is very efficient and robust.
Value recovery from polymer wastes by pyrolysis (1978)

Abstract Pyrolysis of polymer wastes appears to be a suitable means of dealing with an increasingly important environmental problem. To provide background on the pyrolytic behavior of wastes, model mixtures of polyethylene and polystyrene have been pyrolyzed in various gas phases including nitrogen and carbon monoxide, at atmospheric and at reduced pressures and at temperatures from about 300–900°C. When the pyrolyzing temperature is attained by gradual heating, and when pyrolysis occurs at pressures in excess of about 200 torr, the process occurs as if each component were present alone—that is, no evidence for component interaction was noted. In these cases, the known mechanisms for pyrolysis of the pure polymers can be applied to the behavior of mixtures. Complicating effects due to interactions between the starting polymers, or among the pyrolysis products, were observed in low pressure pyrolysis (≲20 torr); further, it was shown that the balance of pyrolysis products depends on rates of attaining the pyrolyzing temperature, more rapid rates favoring the production of carbon‐rich solid residues of possible use as carbon blacks. More detailed understanding of pyrolytic processes in polymer mixtures is needed to permit selection of conditions producing the optimum balance of useful products.
Latency-Optimized Networks for Clustering FPGAs (2013)

The data-intensive applications that will shape computing in the coming decades require scalable architectures that incorporate scalable data and compute resources and can support random requests to unstructured (e.g., logs) and semi-structured (e.g., large graph, XML) data sets. To explore the suitability of FPGAs for these computations, we are constructing an FPGAbased system with a memory capacity of 512 GB from a collection of 32 Virtex-5 FPGAs spread across 8 enclosures. This paper describes our work in exploring alternative interconnect technologies and network topologies for FPGA-based clusters. The diverse interconnects combine inter-enclosure high-speed serial links and wide, single-ended intra-enclosure on-board traces with network topologies that balance network diameter, network throughput, and FPGA resource usage. We discuss the architecture of high-radix routers in FPGAs that optimize for the asymmetry between the interand intra-enclosure links. We analyze the various interconnects that aim to efficiently utilize the prototype's total switching capacity of 2.43 Tb/s. The networks we present have aggregate throughputs up to 51.4 GB/s for random traffic, diameters as low as 845 nanoseconds, and consume less than 12% of the FPGAs' logic resources.
Familial atypical progressive supranuclear palsy associated with homozigosity for the delN296 mutation in the tau gene (2001)

Heterozygous missense and splice-site mutations in the tau gene have been previously identified in familial frontotemporal dementia with autosomal dominant inheritance. Here we report a Spanish kindred in which two brothers born from a third-degree consanguineous marriage were both affected with atypical progressive supranuclear palsy. A homozygous deletion at codon 296 (delN296) was identified in one of the affected siblings. Among the heterozygous carriers, two members with probable Parkinson's disease were identified, but none of heterozygotes developed atypical parkinsonism. The delN296 mutation lies in the sequence corresponding to the second tubulin-binding repeat of tau protein and affects one asparagine residue absolutely conserved in other species. This finding indicates that homozygous mutations in the tau gene may also cause hereditary tauopathies.
Removal of arsenic from synthetic groundwater by adsorption using the combination of laterite and iron-modified activated carbon (2008)

Groundwater is one of the most important sources for drinking water. Arsenic (As) contamination of groundwater is a serious problem worldwide, especially in Bangladesh, India and South East Asia. Adsorption using appropriate and readily available adsorbents is a promising method for the removal of arsenic with applicability in rural areas. This work aims to study the removal of arsenic from synthetic groundwater using an adsorption column by sequential combination of laterite (LA) and iron-modified activated carbon (AC-Fe) as adsorbents. The effect of ratio LA/AC-Fe, flow rate, initial arsenic concentration and pH to the breakthrough time were investigated. Adsorption equilibrium and adsorption kinetics were also studied through batch experiment. The result was found to be an efficient and feasible approach for arsenic treatment from groundwater for ready applicability in rural areas.
Background Measurements with Different Shielding and Anticoincidence Systems (1986)

Extremely low background count rates are a necessary condition for both the measurement of 39 Ar concentrations in ground and ocean water and of 14 C activities in small samples using gas proportional counting techniques. A systematic comparison of the performance of three different designs of shielding systems in four different installations has been made. Background values of selected gas proportional counters were measured, compared and separated into their various components. Acceptably low backgrounds were obtained in all the systems tried. The performance of a NaI shield in a surface laboratory was found to be at least equal to the best obtained with a gas anticoincidence detector in a deep underground laboratory.

Vegetable, fruit and antioxidant nutrient consumption and subsequent risk of hepatocellular carcinoma: a prospective cohort study in Japan (2009)

In a population-based prospective study of 19,998 Japanese individuals, consumption of vegetables, green-yellow and green leafy vegetables was inversely associated with the risk of hepatocellular carcinoma (101 cases), with multivariable hazard ratios for the highest vs lowest tertile of 0.61 (95% confidence interval (CI)=0.36-1.03, P(trend)=0.07), 0.65 (95% CI=0.39-1.08, P(trend)=0.06) and 0.59 (95% CI=0.35-1.01, P(trend)=0.04), respectively.

Gradient-index AR film deposited by the sol–gel process (1982)

Gradient-index alkali borosilicate antireflection films for use in laser systems were deposited by the sol-gel process. Laser damage thresholds of these films, measured with 1.06-microm 1-nsec pulses, were four times greater than thresholds of widely used, multilayer, antireflection coatings.
Non-Axisymmetric Endwall Profiling in a Turbine Rotor Blade (1998)

A non-axisymmetric endwall profile has been designed using CFD with the aim of reducing endwall pressure non-uniformities downstream of a rotor blade. The purpose was to reduce coolant leakage as proposed by Rose (1994). This profile has been manufactured and fitted to the Durham linear cascade. The experimental endwall pressure distribution agrees very well with the CFD predictions giving a substantial reduction in pressure non-uniformity at the equivalent of the platform edge location downstream. Velocity and total pressure measurements have also been made within and downstream of the blade row to investigate the effects of the profile on the cascade secondary flow. Although the experimental results indicate no significant increase in the secondary flows, a small increase in loss is seen. The CFD predicts these trends also but to a smaller extent. This investigation suggests that with three-dimensional endwall design, the pressure field which provides the driving force of secondary flows can be modified without blade redesign.
Change in Heart Rate and Heart Rate Variability During Treatment for Depression in Patients With Coronary Heart Disease (2000)

The results suggest that treating depression with CBT may reduce heart rate and increase short-term HRV. Thus, CBT may have a beneficial effect on a risk factor for mortality in depressed patients with coronary heart disease. A randomized, controlled study is needed to confirm these findings.
A new method for fetal weight estimation using real‐time ultrasound (1987)

A method for estimating fetal weight by calculating an approximate fetal volume from abdominal area, head area and femur length has been developed. Birthweights were calculated within 48 h before delivery for 434 patients, using this method and two other methods already in widespread use. Statistical analysis of the three sets of predictions gave standard deviations of 297 g for the new method, compared with 323 g and 342 g for the other methods. Further analysis of the data showed that estimates closest to the true birthweight were obtained in 41% of cases by using the new method, and in 33% and 26% of cases using the other methods.

Stable Perfluorocarbon Emulsions Using XMO-10 as Surfactant: Potential Oxygen-Carrying Plasma Expanders (1990)

XMO-10, a perfluorocarbon surfactant produced emulsions of a perfluorocarbon (Perfluorotripropylamine, FTPA) in vitro which were stable at a range of temperatures for at least 5 days. Most of the emulsion particles were smaller than 1 micron, and all emulsion particles were of these dimensions when the emulsification mixture included 2% lecithin. XMO-10 produced more stable emulsions with smaller particles than did PF68, a widely-used emulsifying agent. XMO-10 was toxic to cells in culture but this toxicity was reduced or abolished when the XMO-10 was emulsified with perfluorocarbon. XMO-10 and lecithin produced relatively stable emulsions of perflurodecalin. Such emulsions, if non-toxic in vivo, might permit excretion of perfluorocarbon through the lungs and thus would permit infusion of sufficient quantities of the preparations to function in oxygen transport in severely anemic animals and man.

A Pan-European network designed with hybrid all-optical express path routing and OEO-switched shared mesh restoration required 31% fewer transceivers than an all-OEO-switched network and a 60% lower bandwidth-distance product than a 1+1 protected all-optical network
Tagged image clustering via topic models (2015)

With the rapid growth of tagged images, researchers are now resorting to this high semantic textual information for image clustering, which has showed higher clustering performance compared with conventional methods using the low level visual features. However, how to bridge the gap between the semantic information and the visual information is still an open problem. In this paper, a novel topic model based framework is proposed for tagged image clustering, which consists of three steps. Firstly, the statistics between the visual features and the tag features are calculated to utilize the complementary characteristic between the two sources of information. Then the new tag feature embedded by visual information is extracted as the feature of images. Finally, typical topic model, i.e., Latent Dirichlet Allocation, is applied for image clustering. The proposed method can make full use of the tag and visual information for image clustering. Experimental results on two widely used datasets, i.e., Pascal VOC 2007 and NUS-WIDE Flickr databases, demonstrate the effectiveness of the proposed method.
Nanoparticle-Mediated Pulmonary Drug Delivery: A Review (2014)

Colloidal drug delivery systems have been extensively investigated as drug carriers for the application of different drugs via different routes of administration. Systems, such as solid lipid nanoparticles, polymeric nanoparticles and liposomes, have been investigated for a long time for the treatment of various lung diseases. The pulmonary route, owing to a noninvasive method of drug administration, for both local and systemic delivery of an active pharmaceutical ingredient (API) forms an ideal environment for APIs acting on pulmonary diseases and disorders. Additionally, this route offers many advantages, such as a high surface area with rapid absorption due to high vascularization and circumvention of the first pass effect. Aerosolization or inhalation of colloidal systems is currently being extensively studied and has huge potential for targeted drug delivery in the treatment of various diseases. Furthermore, the surfactant-associated proteins present at the interface enhance the effect of these formulations by decreasing the surface tension and allowing the maximum effect. The most challenging part of developing a colloidal system for nebulization is to maintain the critical physicochemical parameters for successful inhalation. The following review focuses on the current status of different colloidal systems available for the treatment of various lung disorders along with their characterization. Additionally, different in vitro, ex vivo and in vivo cell models developed for the testing of these systems with studies involving cell culture analysis are also discussed.

A role for the <i>Plasmodium falciparum</i> RESA protein in resistance against heat shock demonstrated using gene disruption (2005)

During erythrocyte invasion, the Plasmodium falciparum Ring-infected erythrocyte surface antigen (RESA) establishes specific interactions with spectrin. Based on analysis of strains with a large chromosome 1 deletion, RESA has been assigned several functions, none of which is firmly established. Analysis of parasites with a disrupted resa1 gene and isogenic parental or resa3-disrupted controls confirmed the critical role of RESA in the surface reactivity of immune adult sera on glutaraldehyde-fixed ring stages. Absence of RESA did not influence merozoite invasion or erythrocyte membrane rigidity, was associated with a modest increase of cytoadhesion to CD36 under conditions of flow, but resulted in marked susceptibility to heat shock. resa1-KO-infected erythrocytes were prone to heat-induced vesiculation like uninfected erythrocytes, whereas parental or resa3-KO infected erythrocytes remained undamaged. Furthermore, a 6 h exposure of ring stages at 41 degrees C resulted in 33% culture inhibition of resa1-KO parasites while marginally impacting parental and resa3-KO parasite growth. This points to a role for RESA in protecting the infected erythrocyte cytoskeleton during febrile episodes. Infection patterns of resa1-KO and parental parasites in Saimiri sciureus indicated that RESA does not, at least on its own, modulate virulence in the squirrel monkey, as had been previously suggested.
Amplifier techniques for combining low noise, precision, and high-speed performance (1981)

A monolithic operational amplifier is presented which optimizes voltage noise both in the audio frequency band, and in the low frequency instrumentation range. In addition, the design demonstrates that the requirements for low noise do not necessitate compromising the specifications in other respects. Techniques are set forth for combining low noise with high-speed and precision performance for the first time in a monolithic amplifier. Achieved results are: 3 nV//spl radic/Hz white noise, 80 nV/SUB p-p/ noise from 0.1 to 10 Hz, 17 V//spl mu/s slew rate, 63 MHz gain-bandwidth product, 10 /spl mu/V offset voltage, 0.2 /spl mu/V//spl deg/C drift with temperature, 0.2 /spl mu/V/month drift with time, and a voltage gain of two million.
Expression of nucleoside-metabolizing enzymes in myelodysplastic syndromes and modulation of response to azacitidine (2013)

The nucleoside analog azacitidine (AZA) is used in the treatment of myelodysplastic syndromes (MDS), but 30-40% of patients fail to respond or relapse after treatment. Hence, to identify new molecular alterations that allow for identification of patients unlikely to respond to AZA could impact the utility of this therapy. We determined the expression levels of genes involved in AZA metabolism: UCK1, UCK2, DCK, hENT1, RRM1 and RRM2 using quantitative PCR in samples from 57 patients with MDS who received AZA. Lower expression of UCK1 was seen in patients without a response to AZA (median 0.2 vs 0.49 for patients with response to AZA, P=0.07). This difference in UCK1 expression was not influenced by aberrant methylation of the UCK1 promoter. In addition, the seven polymorphic loci found in the coding sequence were not associated with UCK1 gene expression nor AZA response. Silencing of UCK1 by siRNA leads to blunted response to AZA in vitro. The univariate analysis revealed that patients expressing lower than median levels of UCK1 had a shorter overall survival (P=0.049). Our results suggest that expression level of UCK1 is correlated with clinical outcome and may influence the clinical response to AZA treatment in patients with MDS.
Clinical validation of the CHRONIOUS wearable system in patients with chronic disease (2013)

The CHRONIOUS system defines a powerful and easy to use framework which has been designed to provide services to clinicians and their patients suffering from chronic diseases. The system is composed of a wearable shirt that integrate several body sensors, a portable smart device and a central sub-system that is responsible for the long term storage of the collected patient's data. A multi-parametric expert system is developed for the analysis of the collected data using intelligent algorithms and complex techniques. Apart for the vital signals, dietary habits, drug intake, activity data, environmental and biochemical parameters are recorded. The CHRONIOUS platform is validated through clinical trials in several medical centers and patient's home environments recruiting patients suffering from Chronic Obstructive pulmonary disease (COPD) and Chronic Kidney Disease (CKD) diseases. The clinical trials contribute in improving the system's accuracy, while Pulmonologists and Nephrologists experts utilized the CHRONIOUS platform to evaluate its efficiency and performance. The results of the utilization of the system were very encouraging. The CHRONIOUS system has been proven to be a well-validated real-time patient monitoring and supervision platform, providing a useful tool for the clinician and the patient that would contribute to the more effective management of chronic diseases.

XMPP-based wireless sensor network and its integration into the extended home environment (2009)

Wireless sensor networks have significant potential in the home environment. Home application scenarios include monitoring and interaction from several remote or local devices such as mobile phones, televisions or computers. In this paper we propose an architecture for a network based on IP-enabled wireless sensors. The communication system is based on the XMPP-protocol which is shown to be highly suitable for the sensor networks. XMPP provides a push based notification functionality that is especially appropriate for the event-driven paradigm of sensors and also provides the authentication and encryption required for data protection. We also use Atom feeds together with XMPP to enable remote web service-like access to the wireless sensor network. Integration of this XMPP-based wireless sensor network with the standard UPnP media-oriented network is done using a XMPP to UPnP gateway. In this paper, home applications and services are first introduced and different technologies supporting them are described. Next, the benefits of XMPP/IP architecture compared to non-IP sensor networks and to the UPnP based sensor network are discussed. We then present our XMPP-based wireless sensor network, with web-service like access, using XMPP and Atom feeds, also interfacing with UPnP. These solutions have been implemented on internet tablet devices allowing a flexible, highly functional and open system for integrating sensor network with the media environment.
