CODIE: Controlled Data and Interest Evaluation in Vehicular Named Data Networks

Recently, named data networking (NDN) has been proposed as a promising architecture for future Internet technologies. NDN is an extension to the content-centric network (CCN) and is expected to support various applications in vehicular communications [vehicular NDN (VNDN)]. VNDN basically relies on naming the content rather than using end-to-end device names. In VNDN, a vehicle broadcasts an “Interest” packet for the required “content,” regardless of end-to-end connectivity with servers or other vehicles and known as a “consumer. ” In response, a vehicle with the content replies to the Interest packet with a “Data” packet and named as a “provider. ” However, the simple VNDN architecture faces several challenges such as consumer/provider mobility and Interest/Data packet(s) forwarding. In VNDN, for the most part, the Data packet is sent along the reverse path of the related Interest packet. However, there is no extensive simulated reference available in the literature to support this argument. In this paper, therefore, we first analyze the propagation behavior of Interest and Data packets in the vehicular ad hoc network (VANET) environment through extensive simulations. Second, we propose the “CODIE” scheme to control the Data flooding/broadcast storm in the naïve VNDN. The main idea is to allow the consumer vehicle to start hop counter in Interest packet. Upon receiving this Interest by any potential provider, a data dissemination limit (DDL) value stores the number of hops and a data packet needs to travel back. Simulation results show that CODIE forwards fewer copies of data packets processed (CDPP) while achieving similar interest satisfaction rate (ISR), as compared with the naïve VNDN. In addition, we also found that CODIE also minimizes the overall interest satisfaction delay (ISD), respectively.
Evaluation of Bird Detection using Time-lapse Images around a Wind Farm

One of the primary environmental concerns of wind farms is the increase in bird mortality. To assess environmental risks around wind farms, the demand for automatic bird monitoring increases rapidly. Considering recent advancements in object detection methods in computer vision, automated monitoring based on images is promising. However, the accuracy of stateof-the-art methods in a practical environment remains uncertain due to the significant difference between the images taken in a practical environment and those used in generic object detection competitions. This study evaluates these image-based bird detection and classification methods. We also introduce a bird monitoring system with a whole image processing pipeline. For evaluation in a practical environment, we utilize an open-access time-lapse image dataset around a wind farm. As a state-of-the-art method, we include convolutional neural networks, a rising method of deep learning for image recognition, which shows performance improvement.
[Health services for children and the implementation of IMCI in Monkey Bay, Malawi].

OBJECTIVES Examine primary health care services for ill children in a sub-Saharan African country, assess the appropriateness of the Integrated Management of Childhood Illness (IMCI) in such a setting and evaluate its implementation. MATERIAL AND METHODS The study was carried out in March, 2005 in the Monkey Bay area, Malawi, in two state-run health facilities that provide services free of charge and in three privately run facilities that charge user fees. Data was collected from each facility regarding all out-patient visits but in particular of children under five years of age (U5s). Interviews were conducted with health workers and drug inventories were carried out in the facilities. RESULTS Eight out of 10 health workers were trained in IMCI. It was 1.22 times more likely (RR, 95% CI 1.18-1.26) that U5s were brought to a state-run facility than a private one. Around 4/5 of all disease classifications during the research period are dealt with in the IMCI. About half of U5s were classified with malaria, 28% with other respiratory infections, 6% with pneumonia, and 5% with diarrhoea. Most IMCI-recommended drugs were in stock at the time of inspection but all facilities lacked at least one recommended drug. CONCLUSION Results show that IMCI reaches the periphery of the health care system in a low-income country such as Malawi. They confirm that IMCI deals with the majority of diseases affecting U5s in such a setting. User fees seem to influence health care seeking behaviour. It is important to support and strengthen health services for ill children in the area, support continuous education of staff and ensure availability of drugs and equipment.
Relationship between Medical Burden, Depression, and Quality of Life in Psychogeriatric Inpatients: Implications for Providers of Pastoral Care

This study describes medical burden among individuals ⩾ 65 years hospitalized for depression in order to determine its associations with depression and quality of life (QOL) and thus provide suggestions for spiritual care providers. Using reliable, validated measures, the 45 participants who completed the study demonstrated moderate medical burden that was significantly associated with physical QOL but not with mental QOL or depression. Irrespective of the level of medical burden, subjects exhibited significant improvement of both depression and QOL during hospitalization. Results suggest that advocacy by spiritual care providers is essential.
Concise Review: Induced Pluripotent Stem Cells Versus Embryonic Stem Cells: Close Enough or Yet Too Far Apart?

The state of a cell is defined by the genes it transcribes and the epigenetic landscape that regulates their expression. Pluripotent cells have markedly different epigenetic signatures when compared with differentiated cells. Permissive chromatin, high occurrence of bivalent domains, and low levels of heterochromatin allow pluripotent cells to react to distinctive stimuli and undergo changes of cell state by differentiating into various tissues. Differentiated cells can be reprogrammed by a set of transcription factors to induced pluripotent stem cells (iPSC) that convert their transcriptional and epigenetic state to pluripotency and thus closely resemble embryonic stem cells (ESC). However, questions remain on whether the epigenetic reprogramming is complete or if there are some recurring iPSC specific aberrations that impede their full pluripotency potential. For this reason, iPSC need to be closely compared with ESC, which is used as a golden standard for in vitro pluripotency. Transcribed genes, epigenetic landscape, differentiation potential, and mutational load show small but distinctive dissimilarities between these two cell types. STEM CELLS 2012;30:33–41
Myocardial O2 supply and O2 utilization of the right ventricle in pulmonary arterial hypertension

Idiopathic pulmonary arterial hypertension (IPAH) results in increased right ventricular (RV) workload and oxygen demand. Previously, it has been shown that myocardial oxygen consumption (MVO 2 ) of the hypertrophied RV of IPAH patients can be measured using PET and oxygen-15 labeled tracers. This method, however, is less suitable for routine clinical practice. The purpose of the present study was to assess whether MVO 2 could also be determined in the RV of IPAH patients from the clearance of [ 11 C]acetate, a simple method that is in use for MVO 2 measurements of the left myocardium. Seventeen IPAH patients underwent four consecutive PET scans. [ 15 O]H 2 O, [ 15 O]O 2 and [ 15 O]CO scans were used to derive RV flow, oxygen extraction fraction and blood volume, respectively, from which RV MVO 2 was calculated. The rate of clearance K mono and the efflux rate constant k 2 were derived from the [ 11 C]acetate scan. The RV rate pressure product (RPP) was also determined by means of right heart catherization, as an index of the RV MVO 2 and was calculated as the product of systolic pulmonary artery pressure and heart rate. For the total population, both K (r=0.64, P=0.006) and k 2 (r=0.67, P=0.003) showed a significant correlation with RV MVO 2 . They also correlated with RV RPP, K mono : r=0.74, p 0.001; k 2 : r=0.70, p = 0.002. Both quantitative RV MVO 2 measurements significant correlation between [ 11 C]acetate clearance rate K and MVO in the right ventricle is in agreement with previous studies on the left myocardium in both control subjects (r=0.71, p=0.02) and patients with chronic myocardial infarction (r=0.89, p<0.001). 4, 7-10 Little about the rate of clearance of [ 11 C]acetate from the normal right ventricle. Two previous studies reported a mean K mono value of 0.040 to 0.043 min -1 in the normal right ventricle of control subjects, which was significantly lower than values seen in patients with dilated cardiomyopathy. The latter values (0.050 - 0.055 min -1 ) are similar to the values observed in the present study. It has been proposed that the higher clearance rate of [ 11 C]acetate is likely due to an increased RV workload in LV heart failure, i.e. secondary high RV K mono values in the present population of IPAH patients reflect increased oxygen demand of the right myocardium as the result of increased afterload in IPAH. In line with that, the treatment-naïve IPAH patient had the highest RV K mono , k 2 and MVO 2 values, indicative for a high RV oxidative metabolism as a result of untreated IPAH.

Low power analog circuit design for RFID sensing circuits

This paper presents low power circuit design for voltage regulator and resistor to digital converter that are used in a RFID-like sensing circuit for measuring the resistance of a sol-gel sensor. The regulator circuit has simple circuit structure and consumes zero DC current (except the current drained by its load). The resistor to digital converter consists of a cascoded current mirror, a reference resistor and a charge-redistribution (CR) ADC circuit. The proposed circuit techniques reduce the size of the ADC capacitor array by half compared to traditional CR ADCs with the same resolution. The proposed techniques also significantly reduce the circuit power consumption with enhanced measurement accuracy. The proposed circuits and a RFID energy harvesting circuit for powering the proposed circuits are implemented using a 0. 13µ CMOS technology. Circuit simulations are presented to examine the performance of the proposed circuits.
The Bactofilin Cytoskeleton Protein BacM of Myxococcus xanthus Forms an Extended β-Sheet Structure Likely Mediated by Hydrophobic Interactions

Bactofilins are novel cytoskeleton proteins that are widespread in Gram-negative bacteria. Myxococcus xanthus, an important predatory soil bacterium, possesses four bactofilins of which one, BacM (Mxan_7475) plays an important role in cell shape maintenance. Electron and fluorescence light microscopy, as well as studies using over-expressed, purified BacM, indicate that this protein polymerizes in vivo and in vitro into ~3 nm wide filaments that further associate into higher ordered fibers of about 10 nm. Here we use a multipronged approach combining secondary structure determination, molecular modeling, biochemistry, and genetics to identify and characterize critical molecular elements that enable BacM to polymerize. Our results indicate that the bactofilin-determining domain DUF583 folds into an extended β-sheet structure, and we hypothesize a left-handed β-helix with polymerization into 3 nm filaments primarily via patches of hydrophobic amino acid residues. These patches form the interface allowing head-to-tail polymerization during filament formation. Biochemical analyses of these processes show that folding and polymerization occur across a wide variety of conditions and even in the presence of chaotropic agents such as one molar urea. Together, these data suggest that bactofilins are comprised of a structure unique to cytoskeleton proteins, which enables robust polymerization.
Properties of the Lattice-Boltzmann Method for Acoustics

Numerical simulations are performed to investigate the fundamental acoustics properties of the Lattice–Boltzmann method. The propagation of planar acoustic waves is studied to determine the resolution dependence of numerical dissipation and dispersion. The two setups considered correspond to the temporal decay of a standing plane wave in a periodic domain, and the spatial decay of a propagating planar acoustic pulse of Gaussian shape. Theoretical dispersion relations are obtained from the corresponding temporal and spatial analyses of the linearized Navier–Stokes equations. Comparison of theoretical and numerical predictions show good agreement and demonstrate the low dispersive and dissipative capabilities the Lattice–Boltzmann method. The analysis is performed with and without turbulence modeling, and the changes in dissipation and dispersion are discussed. Overall, the results show that the Lattice–Boltzmann method can accurately reproduce time-explicit acoustic phenomena.
Transformationen zur Vermeidung numerischer Dispersion und Verfahren zur Steuerung der Zeitschrittweite für die numerische Optionsbewertung

Die numerische Bewertung amerikanischer Optionen erfordert die Losung eines linearen Komplementaritatsproblems, dessen Bestandteil die Black-Scholes (Un)gleichung ist. Finite-Differenzen-Diskretisierungen dieser partiellen Differentialgleichung (PDE) konnen numerische Dispersion erzeugen. Die daraus resultierenden Oszillationen machen ein Hedging der Option unmoglich. Durch geeignete Transformationen ist es moglich, numerische Dispersion zu vermeiden. Diese Arbeit analysiert die Dispersions-Eigenschaften bekannter und neuer Transformationen der Black-Scholes PDE. Fur dispersionsfreie Transformationen wird das Problem in eine zeitabhangige Folge von Linearen Programmen uberfuhrt. Aufgrund der vorzeitigen Ausubungsmoglichkeit ist fur jeden dieser Zeitschritte eine Glattung der numerischen Losung mittels L-stabiler Diskretisierungsverfahren notwendig. Um den numerischen Aufwand gering zu halten werden verschiedene Verfahren vorgestellt, die die Anzahl der notwendigen Zeitschritte reduzieren. Der Knackpunkt ist dabei der zeitlichen Verlauf der Losung der PDE. Die Black-Scholes PDE ist eine Verwandte der Warmeleitungsgleichung und zeigt ein qualitativ ahnliches Verhalten. Es stellt sich heraus, das diese Schrittweitensteuerung effektiv arbeitet. Trotz der teureren Verwendung einer alternativen Losung wird ein Speed-up zu den bisher gebrauchlichen Verfahren erreicht. Allerdings steckt der Aufwand nun hauptsachlich im Auffinden der Ausubungsgrenze. Die gefundenen Methoden lassen sich auf einige exotische Optionstypen ubertragen.
Scheduling of Distributed Algorithms for Low Power Embedded Systems

Recently, the advent of embedded multicore processors has created interesting technologies for power management. Systems consisting of low-power and high-efficient cores create new possibilities for the optimization of power consumption. However, new design methods, dedicated to these technologies should be developed. In this paper we present a method of static task scheduling for low-power real-time embedded systems. We assume that the system is specified as a distributed algorithm, then it is implemented using multi-core embedded processor with low-power processing capabilities. We propose a new scheduling method to create the optimal or suboptimal schedule. The goal of optimization is to minimize the power consumption while all time constraints will be satisfied or the quality of service will be as high as possible. We present experimental results, obtained for sample systems, showing advantages of our method.
Light intensity fluctuation insensitive faraday polarimeter for atomic magnetometer

Atomic Magnetometer has ranked the highest sensitive magnetometer in recent years. To realize a high performance atomic magnetometer, a well designed polarimeter is required to detect the atomic spin precession. Among various polarimeter techniques available, faraday polarimeter is suitable for high sensitive atomic magnetometer application due to its high angular sensitivity at low frequency range. However, this polarimeter is sensitive to light intensity fluctuation which will decrease the atomic magnetometer sensitivity and its long time performance. Instead of utilizing a light intensity feedback controlled system to active stabilize the light intensity, this paper proposed a faraday polarimeter with light intensity fluctuation compensation capability. The structure and mathematic model of this polarimeter was analyzed, experimental tests were performed. With this polarimeter, the light intensity fluctuation was decreased significantly to 0.001%, and an angular sensitivity of 10−8 rad/Hz1/2 has been achieved.
Fast block matching motion estimation algorithms for video compression

As the telecommunication technology grows in the modern era from internet to video conferencing, Video compression has become an avoidable feature in information broadcast and also in the entertainment media. In this thesis we compared a different block matching motion estimation algorithms to find the motion estimation with a rapid growth of multimedia information; when transmitting a large amount of data video coding standards have become crucial. Motion estimation ascertain to be the key to splendid performance in video coding by recover the temporal redundancy effectively between adjacent frames, so it has been widely used to popular video compression coding standards such as MPEG-2, MPEG-4 and recent video coding standards H.264 of video data for storage and transmission. So Based on the study of motion vector distribution from several commonly used test image sequences, a three step diamond search [TSDS]algorithm for fast block matching motion estimation is proposed in this paper . The performance of this algorithm is compared with other existing algorithms of basic full search [FS], three step search [TSS] and diamond search [DS] by means of error metrics and no of search points in this the simulation results shows that the proposed three step diamond search algorithm achieves close performance with that of diamond search [DS] and uses less no of search points than the three step search[TSS]. When compared with original diamond search [DS] algorithm, this algorithm requires less computation time and gives an improved performance.
Combining adenoviral oncolysis with temozolomide improves cell killing of melanoma cells

Oncolytic Adenoviruses are emerging agents for treatment of cancer by tumor‐restricted virus replication, cell lysis and virus spread. Clinical studies with first generation oncolytic adenoviruses have revealed that an increased potency is warranted in order to achieve therapeutic efficacy. One approach towards this end is to combine adenoviral oncolysis with chemotherapy. Here, a fundamental requirement is that chemotherapy does not interfere with adenovirus replication in cancer cells. We have previously developed a melanoma‐targeted oncolytic adenovirus, Ad5/3.2xTyr, which features tyrosinase promoter regulated replication and enhanced cell entry into melanoma cells. In this study, we investigated a combination treatment of melanoma cells with Ad5/3.2xTyr and temozolomide (TMZ), which produces the same active metabolite as Dacarbazine/DTIC, the standard chemotherapy for advanced melanoma. We report that TMZ does not inhibit adenovirus replication in melanoma cells. Additive or synergistic cell killing of melanoma cells, dependent on the cell line used, was observed. Enhanced cell binding was not responsible for synergism of adenoviral oncolysis and TMZ treatment. We rather observed that higher numbers of virus genomes are produced in TMZ‐treated cells, which also showed a cell cycle arrest in the G2 phase. Our results have important implications for the clinical implementation of adenoviral oncolysis for treatment of malignant melanoma. It suggests that such studies are feasible in the presence of TMZ or DTIC chemotherapy and recommends the investigation of a viro‐chemo combination therapy. © 2007 Wiley‐Liss, Inc.
Angle-resolved photoemission and the electronic structure of Pd(111)

A theoretical study of various models which are commonly used for the analysis of angle-resolved photoemission is reported. For the example of the Pd(111) surface we discuss the quality and justification of these models. %e have calculated the @~I-resolved surface and bulk densities of states and the band structure of occupied and unoccupied states. FurtheHIlore, we have calculated photoemission spectra within the one-step approach. These theoretical spectra reproduce the main features and trends of the experimental data. We find that the k~I-resolved densities of states are, in general, not reflected in the photoemission. The spectra can only be interpreted in a modified direct-transition model where the inf1uence of the inelastic electron-electron interaction in the final state is taken into account.
Transient expression of reporter genes introduced in tissues of two Acacia species using a biolistic method

SummaryThe biolistic method was used to introduced DNA into cotyledons of Acacia mangium and A. mearnsii. The β-glucuronidase gene (gus) and the green fluorescent protein gene (gfp) were tested as reporter genes to study the effects of acceleration pressure and pre- and post-bombardment osmotic treatments. These consisted of incubating the explants in the presence of sucrose, mannitol, and sorbitol for several hours before or after bombardment with microprojectiles. High acceleration pressure slightly enhanced gus expression in both species tissues. Osmotic treatments significantly improved expression of both reporter genes introduced into A. mearnsii cotyledons. The best transient expression was observed in these tissues when they were treated with mannitol and sorbitol (0.3 or 0.4M each) for 3–4h before the bombardment and 3h afterwards. However, the same treatments did not affect the expression of the gus gene introduced in A. mangium explants.
