Fetal cardiovascular dynamics during cardiac dysrhythmia. Case report

Case report A 28-year-old healthy primigravida was seen at 36 weeks gestation with fetal dysrhythmia. Realtime ultrasound examination suggested a variable atrioventricular block. The fetus was of normal size for gestational age without cardiac structural anomalies. There was a slight pericardial effusion but no ascites. The amount of amniotic fluid was normal. The external fetal electrocardiogram (ECG) demonstrated the presence of an atrial flutter of about 460-470 beats/min and a cyclic appearance of the following ventricular rates: a short period of normocardia (a few minutes), a long period of tachycardia (20-30 min), a very short period of bradycardia (a few seconds), a short period of normocardia etc. (Fig. 1; Table 1). M-mode data of cardiac ventricular geometry and function (Wladimiroff & McGhie 1 9 8 1 ~ ; Wladimiroff et al. 1982) were obtained both during normoand tachycardia, but were not technically possible during the very short bradycardia period (Table 1). Statistical analysis of the data was carried out during 10 consecutive cardiac cycles by means of the Wilcoxon rank sum test. Right-to-left ventricular ratio values showed a slight increase in right ventricular transverse dimension both during normoand tachycardia. Left ventricular stroke volume (LVSV), cardiac output (LVCO) and ejection fraction (LVEF) were within the normal range for gestational age during normocardia, but significantly reduced during tachycardia (P<O.OI). Vascular data (Table 1) were obtained through measurement of the mean blood flow velocity and pulsatile vessel diameter at the lower thoracic level of the fetal descending aorta. The blood flow
Dynamic Chunk Allocation and Migration in Cloud Environment

Cloud computing allows the all users to upload and download the resources as per their need. For allocating the resources cloud uses the virtualization concept. It allocates the data center resource to users on demand and minimizes the number of servers. If a load on server increases at that time user cannot get the required result within a time. For that purpose load rebalancing must be done. In this work we are applying the concept of “skewness” to measure the unevenness in utilization of servers. To minimizing the skewness, here we introduce the concept of load Re-balancing in cloud framework. It consider The CPU usage as well as memory for migrate the data object in to the server.
Classifying speech related vs. idle state towards onset detection in brain-computer interfaces overt, inhibited overt, and covert speech sound production vs. idle state

Onset detection is one of the main issues towards self-paced BCIs that can be used outside research settings. For this reason, this paper suggests a potential solution for onset detection problem by discriminating between speech related events. In this study, overt, inhibited overt and covert states were tested to classify from idle state in an off-line setting. Autoregressive model coefficients were used for feature extraction. The results showed that covert speech (vs. idle state) performed the best for all 4 participants. The true positive accuracies were 82.41%, 81.20%, 85.12% and 74.72%, respectively. The bit-transfer rates were 32.95, 16.24, 34.05 and 22.42 per minute, respectively. Compared to a previous study [1], which achieved around 73% accuracy with motor imagery versus idle, this study gave us satisfactory results.
Nanosatellite maneuver planning for point cloud generation with a rangefinder

This paper discusses the application of a single beam laser rangefinder (LRF) to point cloud generation, shape detection, and shape reconstruction for a space-based space situational awareness (SSA) mission. The LRF is part of the payload of a chaser satellite tasked to image a resident space object (RSO). The one-dimensional (1D) nature of LRF returns significantly increases the complexity of the imaging task. To maximize coverage, a method to autonomously detect and fill gaps in sparse point cloud coverage using a narrow field of view (NFOV) camera in conjunction with the LRF is presented. First, relative orbital motion and scanning attitude motion are combined to generate a baseline 3D point cloud of the RSO. The effectiveness of pregenerated command profiles is analyzed by using a weighted edge reconstruction metric that scores how well a point cloud characterizes RSO shape. The design and characterization of multiple relative motion and attitude maneuver profiles, as well as the time and propellant cost of each profile, are presented with the assumption that the entire metrology chain is error free. Next, a three-part algorithm is used that creates a 3D panoramic map from stitched NFOV camera images, correlates the areas of sparse LRF coverage to the map, and generates attitude commands to close the coverage. This provides a consistent and reliable method to register positions of strike points relative to each other and to the NFOV image of the RSO with a priori knowledge of the RSO attitude. Gaps and sparse areas in LRF coverage are covered with strike points; the result is a point cloud of significantly higher resolution than that obtained with preprogrammed attitude profiles. The analysis bears particular relevance to power-constrained nanosatellite missions for space-based SSA for whom a multibeam LRF payload is not feasible. Maneuvers can now be designed on-line in real time; results presented validate the utility of a single-beam LRF as a tool for 3D imaging of RSO shapes.
Temporal trends in the incidence rate of childhood cancer in Germany 1987–2004

The German Childhood Cancer Registry regularly presents graphs of childhood cancer incidence rates by period, but no systematic analysis. The Automated Childhood Cancer Information System‐project found an increasing trend in Europe. Against this background we present the first detailed trend analysis of childhood (aged under 15) malignancies in Germany. We examined incidence rates separately in western Germany 1987–2004 and eastern Germany 1991–2004. We analyzed all malignancies, all main diagnostic groups and relevant subsets using an age‐period‐cohort model. Additionally we fitted fractional polynomials to assess the linearity of the drift. All malignancies combined (excluding Central Nervous System‐tumors and neuroblastoma) show a significant trend: +0.7% in western and +1.1% per year in eastern Germany. The overall trend in Germany is mostly due to the significant increase in lymphoid leukemia, which increased significantly in western Germany (+0.7% per year) and significantly nonlinearly in eastern Germany (+3.3% per year until 1998, +0.8% since 1998), catching up from a level 20% below western Germany. This could be due to life style changes since the reunification in eastern Germany influencing early immune system training. We found no trends for acute non‐lymphocytic leukemia and non‐Hodgkin lymphoma. Hodgkin's disease shows a cohort effect in western Germany after reunification. Improved registration of CNS tumors led to an increase. Neuroblastoma yielded a period effect in western Germany due to screening. With the exception of germ cell tumors, further observations for solid tumor entities are in agreement with those reported for Europe. © 2007 Wiley‐Liss, Inc.
Evaporative fraction from time series of MODIS data to monitor crop status in Northern Italy

Crop monitoring services require the capability to investigate vegetation condition, especially in regions periodically affected by low or erratic rainfalls as recently happened in northern Italy. This paper define an operational methodology based on the “triangle method” to estimate Evaporative Fraction as an indicator of surface moisture condition. The approach, that relies on low resolution MODIS products and air temperature maps, it was applied to the 2010-2014 growing seasons deriving instantaneous maps to represent daily crop conditions. The qualitative assessment of the results shows the agronomical coherence of the estimated variable, and the preliminary multi-annual analyses indicates the approach as a promising tool to support near real time crop monitoring at regional scale.
A Physical Topology Related Overlay Network for the P2P Media Streaming System

Selecting partner candidates for data transferring plays an important role in the P2P (Peer-to-Peer) media streaming system. Most traditional P2P media streaming systems do not consider the physical network among the peers, while selecting partner candidates according to physical network can reduce the latency of the data transferring and improve the quality of service. Aiming at objectives of P2P media streaming system, such as low latency, high QoS, scalability, this paper provides a new method called LandLive which estimates the distance between peers based on landmark network measurement method, and then builds the physical topology related overlay network. The paper also describes detailed algorithms for distance estimation and partner candidates selected method. The simulation demonstrates LandLive can improve the performance of the streaming system significantly.
Agenda benders: modelling the disruptions caused by technology failures in the workplace

There is a need to understand the impact of technology failures on work. In the studies reported here, subjects’ plans at the start of each day were compared with their eventual accomplishments, and failures to carry out plans were investigated. A number of sources of disruption were identified; they included technology failures, which had a particular tendency to act as “agenda benders,” preventing the completion of important activities.
Wilbur R. Knorr on Thābit ibn Qurra: A Case-Study in the Historiography of Premodern Science

There was a widespread belief among historians of science of my generation that high competence with regard to content and languages alone can guarantee better, more reliable results than can good philology combined with high competence in history or the other human sciences. In my casestudy of Wilbur R. Knorr’s analysis of several medieval Arabic and Latin texts on the balance, or steelyard, I highlight a variety of factors that compromised time and again his understanding and interpretation of his chosen texts. I conclude that a greater openness to more complex historiographical assumptions and more sophisticated methodological approaches as well as a greater willingness to contextualize documents in numerous dimensions before coming to conclusions about their specific meaning is crucial if we are to correct and improve upon work such as Knorr’s analysis of the Kitab al-qarastun, ascribed to Thābit ibn Qurra, and the Liber de canonio. The way forward is to enhance and temper philological analysis with solid analysis of scientific content within its relevant contexts.

The UvrD303 Hyper-helicase Exhibits Increased Processivity*

Background: A mutation within the 2B subdomain of UvrD increases helicase activity and impacts phenotype. Results: The unwinding processivity is increased in the UvrD303 mutant. Conclusion: The 2B subdomain of UvrD plays an integral role in regulating helicase activity. Significance: Intramolecular interactions mediate proper activity for UvrD in DNA repair processes. DNA helicases use energy derived from nucleoside 5′-triphosphate hydrolysis to catalyze the separation of double-stranded DNA into single-stranded intermediates for replication, recombination, and repair. Escherichia coli helicase II (UvrD) functions in methyl-directed mismatch repair, nucleotide excision repair, and homologous recombination. A previously discovered 2-amino acid substitution of residues 403 and 404 (both Asp → Ala) in the 2B subdomain of UvrD (uvrD303) confers an antimutator and UV-sensitive phenotype on cells expressing this allele. The purified protein exhibits a “hyper-helicase” unwinding activity in vitro. Using rapid quench, pre-steady state kinetic experiments we show the increased helicase activity of UvrD303 is due to an increase in the processivity of the unwinding reaction. We suggest that this mutation in the 2B subdomain results in a weakened interaction with the 1B subdomain, allowing the helicase to adopt a more open conformation. This is consistent with the idea that the 2B subdomain may have an autoregulatory role. The UvrD303 mutation may enable the helicase to unwind DNA via a “strand displacement” mechanism, which is similar to the mechanism used to processively translocate along single-stranded DNA, and the increased unwinding processivity may contribute directly to the antimutator phenotype.
Title Expression of aquaporin 5 in primary carcinoma and lymph nodemetastatic carcinoma of non-small cell lung cancer

Aquaporin 5 (AQP5), a water channel protein, is highly expressed in non-small cell lung cancer (NSCLC) tissues compared with adjacent normal tissues. AQP5 expression in lung cancer tissues is associated with a poor prognosis. The present study aimed to analyze the expression of AQP5 and investigate its role in primary and lymph node metastatic NSCLCs. An immunohistochemical labeled streptavidin-biotin method was used to determine the expression of AQP5 in 94 cases of NSCLC primary carcinoma, which included 51 cases accompanied by lymph node metastasis. The results revealed that the expression of AQP5 was significantly higher in adenocarcinomas compared with squamous cell carcinomas (P=0.002). In addition, the percentage of AQP5 expression in the primary carcinomas with lymph node metastasis was significantly higher compared with those without lymph node metastasis (P=0.024). However, no statistically significant difference in the percentage of AQP5 expression was observed between the metastatic and the primary carcinomas (P=0.377). The expression of AQP5 exhibited a correlation with the tumor-node-metastasis staging of NSCLC (P=0.027). The percentage of AQP5 expression in stage III and IV tumors was higher than that in stage I and II tumors. In addition, AQP5 expression was correlated with the survival rate of NSCLC patients (P=0.051). In conclusion, the results of the present study provide evidence for the AQP5-facilitated incidence, progression and metastasis of NSCLC. Therefore, AQP5 may be used as a potential target to investigate the incidence, progression and metastasis of NSCLC.
Détection et localisation tridimensionnelle par stéréovision d'objets en mouvement dans des environnements complexes : application aux passages à niveau. (Detection and 3D localization of moving and stationary obstacles by stereo vision in complex environments : application at level crossings)

La securite des personnes et des equipements est un element capital dans le domaine des transports routiers et ferroviaires. Depuis quelques annees, les Passages a Niveau (PN) ont fait l’objet de davantage d'attention afin d'accroitre la securite des usagers sur cette portion route/rail consideree comme dangereuse. Nous proposons dans cette these un systeme de vision stereoscopique pour la detection automatique des situations dangereuses. Un tel systeme permet la detection et la localisation d'obstacles sur ou autour du PN. Le systeme de vision propose est compose de deux cameras supervisant la zone de croisement. Nous avons developpe des algorithmes permettant a la fois la detection d'objets, tels que des pietons ou des vehicules, et la localisation 3D de ces derniers. L'algorithme de detection d'obstacles se base sur l'Analyse en Composantes Independantes et la propagation de croyance spatio-temporelle. L'algorithme de localisation tridimensionnelle exploite les avantages des methodes locales et globales, et est compose de trois etapes : la premiere consiste a estimer une carte de disparite a partir d'une fonction de vraisemblance basee sur les methodes locales. La deuxieme etape permet d'identifier les pixels bien mis en correspondance ayant des mesures de confiances elevees. Ce sous-ensemble de pixels est le point de depart de la troisieme etape qui consiste a re-estimer les disparites du reste des pixels par propagation de croyance selective. Le mouvement est introduit comme une contrainte dans l'algorithme de localisation 3D permettant l'amelioration de la precision de localisation et l'acceleration du temps de traitement.
Effets des stresseurs environnementaux sur la reproduction de l’abeille domestique (Apis mellifera L.) : action par une exposition des mâles

Effets de stresseurs environnementaux sur la fertilite des males chez l'abeille domestique apis mellifera l. en relation avec la fecondite de la reine. Dans un contexte de declin des colonies d’abeilles melliferes, un appauvrissement de la qualite des reines, se traduisant par une production anormale de couvain et des renouvellements prematures de reines, a ete rapporte par les apiculteurs du monde entier. Partant de ce constat, l’hypothese avait ete emise qu’une atteinte de la fertilite des mâles (faux-bourdons), exposes aux stresseurs environnementaux, pouvait etre responsable des defaillances observees chez les reines au sein des ruchers. Dans le but de verifier cette hypothese, des approches novatrices pour elever des faux-bourdons, en conditions controlees de laboratoire et en conditions semi-controlees, ont ete developpees. Les approches mises en oeuvre ont permis de demontrer que l’insecticide systemique Fipronil, la microsporidie pathogene Nosema ceranae et leur association avaient la capacite de generer des perturbations physiologiques de differents types chez les faux-bourdons incluant des alterations de la qualite des semences. De plus, les effets obtenus apres les expositions a ces stresseurs ont montre que la fonction de reproduction de ces individus etait particulierement sensible a l’ensemble des stresseurs etudies. L’insemination instrumentale de jeunes reines, avec des semences de mâles exposes au Fipronil, a mis en lumiere une baisse de leur potentiel reproducteur resultant d’une diminution non seulement du nombre mais aussi de la viabilite des spermatozoides stockes dans la spermatheque. Considerant que le contenu de la spermatheque conditionne leur capacite a pondre et leur longevite, ces reines sont donc plus disposees a presenter des signes de defaillance pouvant se repercuter sur le fonctionnement general de leur colonie. Ainsi, les troubles de la reproduction induits par une baisse de la fertilite des mâles, exposes a une multitude de stresseurs environnementaux, pourraient en partie expliquer le declin des colonies d’abeilles. De ce fait, une evaluation des effets reprotoxiques des substances auxquelles les mâles sont potentiellement exposes, pourrait etre envisagee dans un cadre reglementaire a venir. Ainsi, les methodes et les approches innovantes developpees dans le cadre de ce travail pourraient representer des bases pertinentes pour elaborer de nouveaux tests toxicologiques qui pourraient etre utilises dans la procedure d’enregistrement des pesticides.
ReVAMP: ReRAM based VLIW architecture for in-memory computing

With diverse types of emerging devices offering simultaneous capability of storage and logic operations, researchers have proposed novel platforms that promise gains in energy-efficiency. Such platforms can be classified into two domains — application-specific and general-purpose. The application-specific in-memory computing platforms include machine learning accelerators, arithmetic units, and Content Addressable Memory (CAM)-based structures. On the other hand, the general-purpose computing platforms stem from the idea that several in-memory computing logic devices do support a universal set of Boolean logic operation and therefore, can be used for mapping arbitrary Boolean functions efficiently. In this direction, so far, researchers have concentrated on challenges in logic synthesis (e.g. depth optimization), and technology mapping (e.g. device count reduction). The important problem of efficient technology mapping of arbitrary logic network onto a crossbar array structure has been overlooked so far. In this paper, we propose, ReVAMP, a general-purpose computing platform based on Resistive RAM crossbar array, which exploits the parallelism in computing multiple logic operations in the same word. Further, we study the problem of instruction generation and scheduling for such a platform. We benchmark the performance of ReVAMP with respect to the state of the art architecture.
Detecting psychosocial problems among 5-6-year-old children in preventive Child Health Care: the validity of a short questionnaire used in an assessment procedure for detecting psychosocial problems among children.

BACKGROUND An extended re-assessment of the psychometric properties of the LSPPK, an instrument aimed at identifying children with emotional and behavioural problems. METHODS Data came from a national sample in The Netherlands of parents of 1248 children (aged 5-6 years) interviewed by child health professionals (CHP). Data were obtained regarding psychosocial problems, treatment status and scores on the LSPPK (Parent and CHP Index), and on the Child Behavior Checklist (CBCL). The scale structure, reliability, criterion and content validity and added value of the LSPPK were assessed using the CBCL and treatment status as criteria. RESULTS The scale structure corresponded with that found originally; the LSPPK improved the prediction of problems according to the CBCL, compared to predictions using readily available risk indicators alone. Reliability varied between 0.55 and 0.69. For the LSPPK Parent Index, sensitivity varied between 0.42 and 0.50. For the CHP Index sensitivity varied between 0.60 and 0.96, but specificity varied between 0.76 and 0.79. Both indices were very sensitive for attention and social problems, but less so for other problems. CONCLUSION The LSPPK Parent Index cannot distinguish sufficiently between children with or without serious problems. Either too many children with problems remain unnoticed or too many children without problems are labelled as a case. The LSPPK CHP Index, reflecting the CHP's interpretation of the Parent Index after interviewing the parents does not compensate adequately for the weaknesses of the Parent Index. Better assessment procedures and strategies need to be developed.
