Effiziente Simulation von strukturellen Fehlern für die Zuverlässigkeitsanalyse auf Systemebene

In aktueller Prozesstechnologie muss die Zuverlassigkeit in allen Entwurfsschritten von eingebetteten Systemen betrachtet werden. Methoden, die nur Modelle auf unteren Abstraktionsebenen, wie Gatter- oder Registertransferebene, verwenden, bieten zwar eine hohe Genauigkeit, sind aber zu ineffizient, um komplexe Hardware/Software-Systeme zu analysieren. Hier werden ebenenubergreifende Verfahren benotigt, die auch hohe Abstraktion unterstutzen, um effizient die Auswirkungen von Defekten im System bewerten zu konnen. Diese Arbeit stellt eine Methode vor, die aktuelle Techniken fur die effiziente Simulation von strukturellen Fehlern mit Systemmodellierung auf Transaktionsebene kombiniert. Auf dieseWeise ist es moglich, eine prazise Bewertung der Fehlerauswirkung auf das gesamte Hardware/Software-System durchzufuhren. Die Ergebnisse einer Fallstudie eines Hardware/Software-Systems zur Datenverschlusselung und Bildkompression werden diskutiert und die Methode wird mit einem Standard-Fehlerinjektionsverfahren verglichen
Temporal Extension of Scale Pyramid and Spatial Pyramid Matching for Action Recognition

Historically, researchers in the field have spent a great deal of effort to create image representations that have scale invariance and retain spatial location information. This paper proposes to encode equivalent temporal characteristics in video representations for action recognition. To achieve temporal scale invariance, we develop a method called temporal scale pyramid (TSP). To encode temporal information, we present and compare two methods called temporal extension descriptor (TED) and temporal division pyramid (TDP) . Our purpose is to suggest solutions for matching complex actions that have large variation in velocity and appearance, which is missing from most current action representations. The experimental results on four benchmark datasets, UCF50, HMDB51, Hollywood2 and Olympic Sports, support our approach and significantly outperform state-of-the-art methods. Most noticeably, we achieve 65.0% mean accuracy and 68.2% mean average precision on the challenging HMDB51 and Hollywood2 datasets which constitutes an absolute improvement over the state-of-the-art by 7.8% and 3.9%, respectively.
Multisensor Track Termination for Targets with Fluctuating SNR

In active sonar tracking applications, targets frequently undergo fading detection performance in which the target's detection probability can shift suddenly between high and low values. Using a multistatic active sonar problem, we examine the performance of sequential track termination tests where target detections are based on an underlying hidden Markov model (HMM) with high and low detection states. We show that the Page test is not optimal in this problem and that a K/N track termination rule yields better performance. Further we show that a Bayesian sequential test (the Shiryaev test) yields dramatic performance improvements over both the K/N rule and the Page test.
Constraining the orbit of the possible companion to Beta Pictoris: New deep imaging observations

We recently reported on the detection of a possible planetary-mass companion to Beta Pictoris at a projected separation of 8 AU from the star, using data taken in November 2003 with NaCo, the adaptive-optics system installed on the Very Large Telescope UT4. Eventhough no second epoch detection was available, there are strong arguments to favor a gravitationally bound companion rather than a background object. If confirmed and located at a physical separation of 8 AU, this young, hot (~1500 K), massive Jovian companion (~8 Mjup) would be the closest planet to its star ever imaged, could be formed via core-accretion, and could explain the main morphological and dynamical properties of the dust disk. Our goal was to return to Beta Pic five years later to obtain a second-epoch observation of the companion or, in case of a non-detection, constrain its orbit. Deep adaptive-optics L'-band direct images of Beta Pic and Ks-band Four-Quadrant-Phase-Mask (4QPM) coronagraphic images were recorded with NaCo in January and February 2009. We also use 4QPM data taken in November 2004. No point-like signal with the brightness of the companion candidate (apparent magnitudes L'=11.2 or Ks ~ 12.5) is detected at projected distances down to 6.5 AU from the star in the 2009 data. As expected, the non-detection does not allow to rule out a background object; however, we show that it is consistent with the orbital motion of a bound companion that got closer to the star since first observed in 2003 and that is just emerging from behind the star at the present epoch. We place strong constraints on the possible orbits of the companion and discuss future observing prospects.
Steganography technique using modulus arithmetic

This new technique will use modulus arithmetic to incorporate secret-information into a host-image. Modulus arithmetic is used as the mechanism for embedding and extracting process. Modulus-m operation indicates l-bits of the secret-information can be incorporated into the host-image pixel. This approach works in a fully spatial domain manner, so one need to deliberately observe the spatial characteristic among the pixel distribution in the host-image and the secret-information. Pixels are represented by a decimal value (0 - 255).

Plasma 25-hydroxyvitamin D, lung function and risk of chronic obstructive pulmonary disease

Background 25-hydroxyvitamin D (25(OH)D) may be associated with lung function through modulation of pulmonary protease-antiprotease imbalance, airway inflammation, lung remodelling and oxidative stress. We examined the association of plasma 25(OH)D levels with lung function, lung function decline and risk of chronic obstructive pulmonary disease (COPD). Methods Plasma 25(OH)D was measured in 10 116 participants in the Copenhagen City Heart Study and in 8391 participants in the Copenhagen General Population Study. In the former study, up to three measurements of lung function spanning 20 years allowed analyses of lung function decline. Results In both cohorts, forced vital capacity in % of predicted was 7% lower and forced expiratory volume in 1 s in % of predicted was 7–10% lower for lowest versus highest decile of 25(OH)D (ptrend≤1×10−28). In prospective analyses, participants in the lower versus higher 25(OH)D quintiles had a faster decline in forced expiratory volume in 1 s % predicted (pinteraction=1×10−7) and forced vital capacity % predicted (pinteraction=8×10−8). In cross-sectional analyses, multivariable adjusted ORs for COPD were 2.30 (95% CI 1.55 to 3.41) and 3.06 (1.97 to 4.76) for lowest versus highest quintile in the Copenhagen City Heart Study using Global Initiative for Chronic Obstructive Lung Disease (GOLD) and lower limit of normal criteria. The corresponding ORs were 1.82 (1.13 to 2.92) and 2.23 (1.35 to 3.69) in the Copenhagen General Population Study. In prospective analyses, corresponding multivariable adjusted HRs for developing COPD were 1.58 (1.05 to 2.40) and 2.00 (1.19 to 3.36). Conclusions We observed a novel association of lower plasma 25(OH)D levels with faster decline in lung function and with a higher risk of COPD in prospective analyses.
Y3IP1, a Nucleus-Encoded Thylakoid Protein, Cooperates with the Plastid-Encoded Ycf3 Protein in Photosystem I Assembly of Tobacco and Arabidopsis[W][OA]

Ycf3 is a plastid-encoded gene known to function in the assembly of photosystem I (PSI). This study revealed that Ycf3-interacting protein 1, a nucleus-encoded thylakoid protein, interacts with Ycf3 to promote the assembly of PSI units in the thylakoid membrane. The intricate assembly of photosystem I (PSI), a large multiprotein complex in the thylakoid membrane, depends on auxiliary protein factors. One of the essential assembly factors for PSI is encoded by ycf3 (hypothetical chloroplast reading frame number 3) in the chloroplast genome of algae and higher plants. To identify novel factors involved in PSI assembly, we constructed an epitope-tagged version of ycf3 from tobacco (Nicotiana tabacum) and introduced it into the tobacco chloroplast genome by genetic transformation. Immunoaffinity purification of Ycf3 complexes from the transplastomic plants identified a novel nucleus-encoded thylakoid protein, Y3IP1 (for Ycf3-interacting protein 1), that specifically interacts with the Ycf3 protein. Subsequent reverse genetics analysis of Y3IP1 function in tobacco and Arabidopsis thaliana revealed that knockdown of Y3IP1 leads to a specific deficiency in PSI but does not result in loss of Ycf3. Our data indicate that Y3IP1 represents a novel factor for PSI biogenesis that cooperates with the plastid genome-encoded Ycf3 in the assembly of stable PSI units in the thylakoid membrane.
Inmate Perceptions: The Impact of a Prison Animal Training Program Background

The purpose of this qualitative study was to explore the perceptions of jail inmates participating in the Paws and Stripes College program. The Paws and Stripes College program involves incarcerated inmates training local humane shelter canines’ obedience training techniques using the canine good citizen model as well as teaching the canines skills in which to participate as comfort/emotional support dogs. Using secondary data from self-report questionnaires completed by the inmates, this study sought to explore how the inmates felt before and after their exposure to the Paws and Stripes College program. Specifically, if the inmates felt that participation in the program was beneficial to them or not, and if so, how.
More Than an Interface - SCSI vs. ATA

This paper sets out to clear up a misconception prominent in the storage community today, that SCSI disc drives and IDE (ATA) disc drives are the same technology internally, and differ only in their external interface and in their suggested retail price. The two classes of drives represent two different product lines aimed at two different markets. In fact, both classes contain a range of products that address a variety of features and usage patterns beyond simply the interface used to talk to the device. The target market and final product specification are taken into account from the earliest design decision through the manufacturing and testing process. This paper attempts to clarify the differences by illuminating some of these design choices and their consequences on final device characteristics. This will hopefully allow the community to build better storage systems with better knowledge of the trade-offs being made and the performance characteristics that result.
Is Financial Friction Irrelevant to the Great Depression? - Simple modification of the Carlstrom-Fuerst model -

It is argued that existing theory implies that financial frictions appear as investment wedges. Since data show that the output declines in the Great Depression were mainly due to the productivity declines, it is also argued that financial frictions may not be the primary cause of the depression. By slightly modifying the model of Carlstrom and Fuerst (1997), I show that financial frictions may show up as declines in productivity. This result may restore the relevance of financial frictions to the Great Depression and other depression episodes, such as Japan's "lost decade. "
No Increased Risk for Primary Osteoarthritis in Liver Cirrhosis – A Danish Nationwide Cohort Study

Objective Chronic synovial inflammation causes primary osteoarthritis, but it is unknown whether chronic systemic inflammation does, too. Patients with cirrhosis have chronic systemic inflammation and therefore we examined the association between cirrhosis and primary osteoarthritis of the hip and knee. Methods In Danish healthcare databases we identified all residents over 60 years diagnosed with cirrhosis in 1994–2011, and for each of them we sampled five age- and gender-matched reference persons from the general population. We excluded everyone with risk factors for secondary osteoarthritis and computed incidence rates of primary osteoarthritis of the hip or knee. We used stratified Cox regression to estimate the hazard ratios of primary osteoarthritis for cirrhosis patients vs. reference persons in strata defined by gender, age, cirrhosis etiology, and ascites vs. no ascites. We also computed separate HRs for primary osteoarthritis of the hips or knees. Results We identified 10,049 cirrhosis patients. Their median age was 67 years, and 65% were men. Among the cirrhosis patients the crude incidence rate of primary osteoarthritis was 8.40 (95% CI: 7.30–9.63) per 1000 person-years. The rate was similar in the reference persons: 8.76 (95% CI: 8.43–9.12) per 1000 person-years. Accordingly, the hazard ratio for primary osteoarthritis for cirrhosis patients vs. reference persons was 0.99 (95% CI: 0.85–1.16), and we found the same null association in all patient strata and in both joints. Conclusion Cirrhosis, and thus chronic systemic inflammation, is not a risk factor for primary osteoarthritis.
More on BPS solutions of N = 2, D = 4 gauged supergravity

We deepen and refine the classification of supersymmetric solutions to N = 2, D = 4 gauged supergravity obtained in a previous paper. In the case where the Killing vector constructed from the Killing spinor is timelike, it is shown that the nonlinear partial differential equations determining the BPS solutions can be derived from a variational principle. The corresponding action enjoys a solution-generating PSL(2, ) symmetry. In certain subcases the system reduces to different known theories, like two-dimensional dilaton gravity or the dimensionally reduced gravitational Chern-Simons theory. We find new supersymmetric solutions including, among others, kinks that interpolate between two AdS4 vacua, electrovac waves on anti-Nariai spacetimes, or generalized Robinson-Trautman solutions. In the case where the Killing vector is null, we obtain a complete classification. The one quarter and one half supersymmetric solutions are determined explicitely, and it is shown that the fraction of three quarters of supersymmetry cannot be preserved. Finally, the general lightlike configuration is uplifted to eleven-dimensional supergravity.
Accounting for local meteorological effects in the ozone time-series of Lovozero (Kola Peninsula)

The relationship between local meteorological conditions and the surface ozone variability was studied by means of statistical modeling, using ozone and meteorological parameters measured at Lovozero (250 m a.s.l., 68.5°N, 35.0°E, Kola Peninsula) for the period of 1999-2000. The regression model of daily mean ozone concentrations on such meteorological parameters as temperature, relative humidity and wind speed explains up to 70% of day-to-day ozone variability in terms of meteorological condition changes, if the seasonal cycle is also considered. A regression model was created for separated time scales of the variables. Short-term, synoptical and seasonal components are separated by means of Kolmogorov-Zurbenko filtering. The synoptical scale variations were chosen as the most informative from the point of their mutual relation with meteorological parameters. Almost 40% of surface ozone variations in time periods of 11-60 days can be explained by the regression model on separated scales that is 30% more efficient than ozone residuals usage. Quantitative and qualitative estimations of the relations between surface ozone and meteorological predictors let us preliminarily conclude that at the Lovozero site surface ozone variability is governed mainly by dynamical processes of various time scale rather than photochemistry, especially during the cold season.
Multiple memory traces after associative learning in the honey bee antennal lobe

We investigated the effect of associative learning on early sensory processing, by combining classical conditioning with in vivo calcium‐imaging of secondary olfactory neurons, the projection neurons (PNs) in the honey bee antennal lobe (AL). We trained bees in a differential conditioning paradigm in which one odour (A+) was paired with a reward, while another odour (B−) was presented without a reward. Two to five hours after differential conditioning, the two odour–response patterns became more different in bees that learned to discriminate between A and B, but not in bees that did not discriminate. This learning‐related change in neural odour representations can be traced back to glomerulus‐specific neural plasticity, which depended on the response profile of the glomerulus before training. (i) Glomeruli responding to A but not to B generally increased in response strength. (ii) Glomeruli responding to B but not to A did not change in response strength. (iii) Glomeruli responding to A and B decreased in response strength. (iv) Glomeruli not responding to A or B increased in response strength. The data are consistent with a neural network model of the AL, which we based on two plastic synapse types and two well‐known learning rules: associative, reinforcer‐dependent Hebbian plasticity at synapses between olfactory receptor neurons (ORNs) and PNs; and reinforcer‐independent Hebbian plasticity at synapses between local interneurons and ORNs. The observed changes strengthen the idea that odour learning optimizes odour representations, and facilitates the detection and discrimination of learned odours.
Identification of an Acute Ethanol Response Quantitative Trait Locus on Mouse Chromosome 2

A two-stage strategy was used to identify and confirm quantitative trait loci (QTLs) associated with the changes in locomotor activity induced by a 1.5 gm/kg ethanol challenge. For stage 1, putative QTLs were identified by analysis of the strain means for 25 strains of the BXD recombinant inbred (RI) series (males only). QTLs were identified on chromosomes 1, 2, 4, and 6. The activity response to chlordiazepoxide generated similar QTLs on chromosomes 2 and 6. None of the QTLs were similar to those generated from analysis of the saline response data. For stage 2, 900 male C57BL/6J (B6) × DBA/2J (D2) F2 intercross animals were phenotyped for ethanol response, and the phenotypic extremes (those animals > and <1 SD from the mean) were identified. These extremes differed by >10,000 cm/15 min in their response to ethanol. The extreme progeny were used for a genome-wide scan both to confirm the putative RI-generated QTLs and to detect new QTLs. The F2 analysis generated no new QTLs with logarithm of the likelihood for linkage (LOD) scores >3. For RI-generated QTLs, only the QTL on chromosome 2 was confirmed (LOD = 5.3). The position of the peak LOD was estimated to be 47 cM with a 20 cM 1 LOD support interval; this QTL accounted for 6% of the phenotypic variance. The 1 LOD support interval overlaps with QTLs previously identified for alcohol preference and acute ethanol withdrawal (Melo et al., 1996; Buck et al., 1997; Phillips et al., 1999).
Best SubTree genetic programming

The result of the program encoded into a Genetic Programming(GP) tree is usually returned by the root of that tree. However, this is not a general strategy. In this paper we present and investigate a new variant where the best subtree is chosen to provide the solution of the problem. The other nodes (not belonging to the best subtree) are deleted. This will reduce the size of the chromosome in those cases where its best subtree is different from the entire tree. We have tested this strategy on a wide range of regression and classification problems. Numerical experiments have shown that the proposed approach can improve both the search speed and the quality of results.
Numb controls E-cadherin endocytosis through p120 catenin with aPKC

We found that Numb directly binds to p120. Numb depletion impaired E-cadherin internalization. aPKC phosphorylated Numb and inhibited its association with p120. In the Numb-depleted cells, the phosphomimetic Numb mutant failed to restore E-cadherin internalization. We propose the mode of action of Numb for intercellular adhesion downstream of aPKC.
