Zum Einfluss vorschulischer Kinderbetreuung auf den Bildungsweg und den erwarteten Erfolg am Arbeitsmarkt

In dem Beitrag wird der Frage nachgegangen, welchen Einfluss die Inanspruchnahme fruhkindlicher Bildungs- und Betreuungsangebote auf den spateren Schulbesuch von Kindern hat und wie sich dies langerfristig auf die zu erwartenden Lebenseinkommen und damit einhergehend den langfristigen volkswirtschaftlichen Nutzen auswirkt. Untersucht werden Kinder in Deutschland der Jahrgange 1990 bis 1995. Die Datengrundlage liefert das Sozio-oekonomische Panel (SOEP). Der Schwerpunkt der Analysen liegt auf der Bestimmung des Effekts des Krippenbesuchs auf die spatere Einstufung in die verschiedenen Schultypen in Abhangigkeit der sozialen Herkunft und des Migrationshintergrunds der Kinder. Ausgehend von diesen Schatzungen werden dann die zu erwartenden, uber den Bildungsabschluss vermittelten Auswirkungen des Krippenbesuchs auf das spatere Lebenseinkommen bestimmt, um einen Eindruck der langfristigen volkswirtschaftlichen Folgen vorschulischer Kinderbetreuung zu erhalten. Der Beitrag zeigt, dass der Krippenbesuch die Wahrscheinlichkeit einer Einstufung ins Gymnasium nach Kontrolle relevanter Drittvariablen im Schnitt um rund 14 Prozentpunkte erhoht. Dieser Einfluss entspricht einem erwarteten Lebenseinkommenszuwachs von rund 27000 Euro. Wird dieser Ertrag auf den Zeitpunkt des Krippenbesuchs abdiskontiert und den Kosten eines durchschnittlichen Krippenbesuchs in der Hohe von rund 8000 Euro gegenubergestellt, so ergibt sich ein Kosten-Nutzen-Verhaltnis von 1 zu 2.7. (DIPF/Orig.).
Adenosine transport in rat liver plasma membrane vesicles.

Liver plasma membrane ecto-ATPase activity is largely restricted to the bile canalicular membrane. To determine whether a transport process is also selectively present on this membrane surface to reclaim adenosine derived from the intracanalicular degradation of ATP, the characteristics of hepatic nucleoside transport were examined in canalicular (cLPM) and basolateral (blLPM) rat liver plasma membrane vesicles. In the presence of the adenosine deaminase inhibitor, deoxycoformycin, an inwardly directed Na+ gradient markedly stimulated [3H]adenosine uptake in cLPM vesicles. Canalicular Na(+)-dependent [3H]adenosine uptake was enhanced by an intravesicular-negative membrane potential and inhibited by dissipation of the Na+ gradient with gramicidin D. Both purine and pyrimidine nucleosides inhibited canalicular adenosine transport. 6-[(4-Nitrobenzyl)thio]-9-beta-D-ribofuranosylpurine, an inhibitor of nucleoside transport in erythrocytes and nonepithelial cells, had no effect on canalicular adenosine transport. Canalicular Na(+)-dependent [3H]adenosine uptake exhibited saturability with a Michaelis-Menten constant of 8.3 microM and a maximum transport rate of 7.6 pmol.5 s-1.mg protein-1. In contrast, [3H]adenosine uptake in blLPM vesicles was not stimulated by an inwardly directed Na+ gradient. These findings demonstrate asymmetric distribution of hepatic Na(+)-dependent nucleoside transport. Reclamation of intracanalicular adenosine resulting from ecto-ATPase activity may explain the presence of this transport process selectively on the bile canalicular membrane.
Survey paper on Generalized Inverted Index for Keyword Search

Inverted lists are normally used to index selected documents to acess the documents according to a set of keywords efficiently. Since inverted lists are normally large in size, many compression techniques have been proposed to minimize the storage space and disk I/O time.This paper presents we propose improved technologies for document identifier assignment a more convenience index structure, the Generalized Inverted Index which merges consecutive IDs in inverted lists into intervals to avoid large storage space. With this index structure, more efficient algorithms can be devised to implement basic keyword search operations. The performance of generalized inverted index is also improved by reordering the documents in datasets using two scalable new algorithms. Experiments on the performance and scalability of generalized inverted index on real datasets prove that Generalized Inverted Index requires minimum storage space as well as increases the keyword search performance, as compared to the old inverted indexes.
Model-free control for soft manipulators based on reinforcement learning

Most control methods of soft manipulators are developed based on physical models derived from mathematical analysis or learning methods. However, due to internal nonlinearity and external uncertain disturbances, it is difficult to build an accurate model, further, these methods lack robustness and portability among different prototypes. In this work, we propose a model-free control method based on reinforcement learning and implement it on a multi-segment soft manipulator in 2D plane, which focuses on the learning of control strategy rather than the physical model. The control strategy is validated to be effective and robust in prototype experiments, where we design a simulation method to speed up the training process.
Angiographic embolization for intractable obstetrical bleeding

Aims and Objectives: The objective of this study is to review the clinical profile and outcome in patients requiring the angiographic embolization in obstetrics. Methods: The retrospective data of patients requiring uterine artery embolization for control of obstetrical hemorrhage was studied during the period from August, 2005 to August, 2010. Results: A total of 35 patients with obstetrical hemorrhage (seven post lower segment caesarean section, 13 post vaginal delivery, 13 postabortal, one with cervical pregnancy and one patient post laparotomy for abdominal pregnancy) underwent angiographic embolization for control of bleeding. In all patients, hemorrhage was successfully controlled; none required post procedure hysterectomy and one patient subsequently became pregnant with in a year. Conclusion: Our clinical experience suggests that embolization is superior first-line alternatives to surgery for control of obstetric hemorrhage including postpartum, post-cesarean and postabortal bleeding and prevents hysterectomy.
Coagulopathy after reinfusion of autologous scavenged red blood cells.

C ' ell scavenging techniques reduce homologous blood transfusion (1-5). Coagulopathy, one of t the potential hazards of reinfusing scavenged autologous blood, is an infrequent occurrence when automated cell processing systems are used to collect, anticoagulate, and wash scavenged red blood cells (1-5). Bleeding problems associated with autologous red blood cell administration are believed to be primarily a result of dilutional rather than disseminated coagulopathy (6-9). When disseminated intravascular coagulopathy is observed during the reinfusion of scavenged autologous blood, concomitant problems such as shock and tissue trauma, rather than the autologous red blood cells per se, are the usual causes of the coagulopathy (6,7). We describe two patients who experienced disseminated coagulopathy after reinfusion of autologous scavenged red blood cells collected during elective surgery for scoliosis correction.
Effects of irradiated diets on production of progeny by several successive generations of the Indian-meal moth, Plodia interpunctella (Hübner).

Indian meal moths, Plodia interpunctella, were reared for nine generations on an irradiated whole wheat flour diet or for four generations on irradiated raisins. Diets were treated with dosages of 0, 25, 50, 100, 500, 1000, and 4300 krad of gamma radiation. Each generation was checked for fecundity and for altered sex ratios. No statistically or biologically significant effects on the numbers of progeny or their sex ratio were found. Irradiated flour and raisins appear to be safe as insect culture media.
YsbA and LytST are essential for pyruvate utilization in Bacillus subtilis

The genome of Bacillus subtilis encodes homologues of the Cid/Lrg network. In other bacterial species, this network consists of holin- and antiholin-like proteins that regulate cell death by controlling murein hydrolase activity. The YsbA protein of B. subtilis is currently annotated as a putative antiholin-like protein that possibly impedes cell death, whereas YwbH is thought to act as holin-like protein. However, the actual functions of YsbA and YwbH in B. subtilis have never been characterized. Therefore, we examined the impact of these proteins on growth and cell death in B. subtilis. We did not find a connection to the regulation of programmed cell death, but instead, our experiments reveal that YsbA and its two-component regulator LytST are essential for growth on pyruvate. Moreover, deletion of ysbA and lytS significantly reduces pyruvate consumption. Our findings suggest that LytST induces ysbA transcription in the presence of pyruvate, and that YsbA is involved in pyruvate utilization presumably by functioning as pyruvate uptake system. We show that B. subtilis excretes pyruvate as overflow metabolite in rich medium, indicating that pyruvate could be a common nutrient in the environment. Hence, YsbA and LytST might play a major role in environmental growth of B. subtilis.
The intelligent parking lot based on ZigBee technology and SVM

Recently, due to the development of automobile industry, the number of vehicles is increasing. The traditional parking lots are unable to meet the growing demands from so many vehicles. Therefore, the current parking lots present many problems. Such as, can't find parking spaces quickly, difficult to manage too many vehicles and manual toll collection costs much time. To solve those problems above, this paper designs a new parking lot system which is based on ZigBee technology and Support Vector Machine (SVM). By the designed parking system, the parking issues can be solved more efficiently and intelligently.
Larger Islands House More Bacterial Taxa

The power law that describes the relationship between species richness and area size is one of the few generalizations in ecology, but recent studies show that this relationship differs for microbes. We demonstrate that the natural bacterial communities inhabiting small aquatic islands (treeholes) do indeed follow the species-area law. The result requires a re-evaluation of the current understanding of how natural microbial communities operate and implies that analogous processes structure both microbial communities and communities of larger organisms.
CCL 18 promotes epithelial-mesenchymal transition , invasion and migration of pancreatic cancer cells in pancreatic ductal adenocarcinoma

CCL18 is a chemokine that is primarily expressed in monocytes, macrophages and immature dendritic cells and plays a crucial role in immune and inflammation responses. Recently, CCL18 was found to play pivotal roles in the development of several kinds of cancers, but its expression status and role during the tumorigenesis of pancreatic cancer remain unknown. In this study, we performed immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) to evaluate the expression of CCL18 in human pancreatic ductal adenocarcinoma (PDAC) tissues and preoperative serum, respectively. The results showed that both cancer epithelial cells and mesenchymal macrophages in PDAC tissues positively expressed CCL18. Serum CCL18 levels were significantly higher in patients with PDAC in comparison to healthy controls. The expression of CCL18 in both cancer epithelial cells and mesenchymal cells was correlated with lymph node metastasis, histopathological grading and overall survival in 62 PDAC patients. In vitro assays showed that the gene and protein expression of CCL18 from U937 and THP-1 cellderived macrophages were significantly higher than that from unstimulated U937 cells and THP-1 cells. In contrast, pancreatic cancer cell lines showed little to no CCL18 expression even after IL4 stimulation. Intriguingly, pancreatic cancer cell lines expressed the potential CCL18 receptors PITPNM3, CCR6 and GPR3. Furthermore, treatment with recombinant human CCL18 promoted the migration and invasion of pancreatic cancer cells, but had no effect on cell proliferation. Consistent with these results, CCL18 induced the expression of the epithelial-mesenchymal transition (EMT) related gene SNAIL1. Our findings suggest that the serum level of CCL18 is a potential biomarker for the diagnosis and prognosis of PDAC, and that the combined functions of CCL18 in mesenchymal and cancer cells might accelerate the progression of PDAC by promoting the epithelial-mesenchymal transition, invasion and migration of pancreatic cancer cells.
AODV with sufficient bandwidth aware routing protocol

Congestion is a major problem in mobile ad hoc network (MANET) which causes long delay and significant loss of data packets, and increases the routing overhead and battery power consumption. The shortest path route seldom offers the optimal route, especially when it traverses the congested area of the mobile network. This paper proposes a novel AODV with Sufficient Bandwidth Aware (AODV+SBA) routing protocol which significantly improves the performance of on-demand routing protocols by discovering better routes to avoid congestion and reducing excessive routing overhead. The ns-2 simulation results illustrate the improvement of network performance and stability by reducing data packet delay and routing overhead and increasing packet delivery ratio, under high traffic load. Moreover, in case of low-to-medium traffic load, its performance is close to the popular AODV routing protocol and the quality of its properties is maintained.
A Novel PWM High Voltage Conversion Ratio Bidirectional Three-Phase DC/DC Converter With Y–Δ Connected Transformer

In order to solve the problem of high voltage conversion ratio between dc bus and energy storage unit, a novel bidirectional three-phase dc/dc converter applicable to high-power condition is proposed in this paper. With the new PWM strategy and inherent ability of increasing voltage conversion ratio of Y-Δ connected transformer, the voltage conversion ratio is doubled. With the new PWM strategy, the effective duty cycle range of three-phase dc/dc converter is expanded, which results in halved filter inductance. Three-phase full-bridge structure is connected to the dc bus, while current-tripler unit is connected to the battery. As three-phase interleaved structure is adopted, not only current stress of switches decreases but also the frequency of input and output current ripple increases to three times of switching frequency, which leads to smaller filters and extended lives cycle of batteries. The operating principle and characteristics of the converter are analyzed in detail. A prototype with the 360-V dc bus converted to 48 V/42 A batteries was built and the results are given based on the experiments.
Compact $S$ -Band Coaxial Cavity Resonator Filter Fabricated By 3-D Printing

This letter presents a novel fourth-order coaxial cavity resonator bandpass filter with a Chebyshev response. The filter operates at a center frequency of 3 GHz and has a bandwidth of 90 MHz. The filter is formed of four coupled coaxial cavity resonators. To make the filter compact, the first resonator is embedded inside the inner conductor of the second resonator and the fourth resonator is embedded inside the central conductor of the third resonator. The filter is fabricated stereolithography apparatus 3-D by printing process that allows such a design with a complex structure to be fabricated accurately at a reasonable cost. The filter is tested and good agreement between measured and simulated results is obtained.
Evaluation of QoS parameters with RPL protocol in the Internet of Things

The objective of this work is to present an analysis of RPL Routing protocol for Low-Power and Lossy Networks (LLNs) in the Internet of Things (IoT) and to determine the adequate working mode between storing and non-storing. Objects in LLNs networks have limited processing power such as battery and memory. The study examined the behavior of RPL towards some number of quality of service parameters in Wireless Sensor Networks (WSNs). Simulations are conducted under ContikiCooja Simulator. Results show that non-storing mode has better results in terms of delay and loss rate, but the storing mode consumes less energy.
Imaging of the guinea pig cochlea following round window gadolinium application

Precise, non-invasive determination of the aetiology and site of pathology of inner ear disorders is difficult. The aim of this study was to describe an alternative method for inner ear visualization, based on local application of the paramagnetic contrast agent gadolinium. Using a 4.7 T MRI scanner, high contrast images of all four cochlear turns were obtained 3.5 h after placing gadolinium on the round window membrane. Gadolinium cleared from the cochlea within 96 h. Auditory brainstem response measurements performed on a separate group of animals showed no significant threshold shifts after the application, indicating that gadolinium is non-toxic to the guinea pig cochlea.
A survey of spectral factorization methods

Spectral factorization is a crucial step in the solution of linear quadratic estimation and control problems. It is no wonder that a variety of methods has been developed over the years for the computation of canonical spectral factors. This paper provides a survey of several of these methods with special emphasis on clarifying the connections that exist among them. While the discussion focuses primarily on scalar‐valued rational spectra, extensions to non‐rational and vector‐valued spectra are briefly noted. Copyright © 2001 John Wiley & Sons, Ltd.
A visual multi-scale spatial clustering method based on graph-partition

Spatial data mining is the process of discovering interesting and previously unknown, but potentially useful patterns from large spatial databases. Extracting interesting and useful patterns from spatial datasets is more difficult than extracting patterns from traditional numeric and categorical data due to the complexity of spatial data types, spatial relationships, and spatial autocorrelation. In this paper, we provide a new visual hierarchical clustering based on graph-partitioning algorithm called VSG-CLUST, which groups and visualizes cluster hierarchies consisting of both non-spatial and spatial attributes. Our method is fundamentally different from conventional clustering algorithms, that usually do not take into account the spatial structure, which refers to the distance between patterns, topology, density, and other spatial distribution characteristics, and lack efficient level-of-detail strategy for visualization. In contrast, VSG-CLUST is able to recognize spatial patterns that involve neighbors. With the help of tree graph our method converts a multidimensional spatial clustering problem to a graph partitioning (tree partitioning) problem. We provide a theoretical basis for the approach and demonstrate the capability of the graph for maintaining the spatial structure. VSG-CLUST is implemented in a fully open and interactive manner, and it supports various visualization techniques including data mining algorithm visualization. A Web-based working demo with Fujian province environmental monitoring data is presented to illustrate the usability and effectiveness of VSG-CLUST and the proposed scheme.
Bewertung von Stückzahl-und Variantenflexibilität in der Produktion

Kurzfassung Die zunehmende Erhöhung der Variantenvielfalt von Produkten stellt eine Herausforderung an alle Bereiche der Unternehmung dar. Im Kontext der Produktion heißt dies vor allem eine optimale Flexibilität der eingesetzten Produktionssysteme zu finden. Zu dem Zeitpunkt strategischer Marktentscheidungen liegen meistens noch sehr wenige Daten über Stückzahlverläufe und Variantenoptionen eines Produktes vor, sodass eine Analyse der Herstellkosten und damit eine optimale Auswahl und Gestaltung des Produktionssystems schwierig ist. Im Rahmen des Verbundforschungsprojekts VireS (Virtuelle Synchronisation von Produktentwicklung und Produktionssystementwicklung) wurde am Institut für Produktionstechnik (wbk) der Universität Karlsruhe ein Simulationsalgorithmus entwickelt und implementiert, der ausgehend von den in frühen Planungsphasen verfügbaren Daten den Kostenverlauf eines Produktionssystems in Abhängigkeit von Varianten- und Stückzahlbereichen über dessen Lebenszyklus abbildet. Dabei spielen stochastische Umwelteinflüsse eine zentrale Rolle.
Meridional and Zonal Wavenumber Dependence in Tracer Flux in Rossby Waves

Eddy-driven jets are of importance in the ocean and atmosphere, and to a first approximation are governed by Rossby wave dynamics. This study addresses the time-dependent flux of fluid and a passive tracer between such a jet and an adjacent eddy, with specific regard to determining zonal and meridional wavenumber dependence. The flux amplitude in wavenumber space is obtained, which is easily computable for a given jet geometry, speed and latitude, and which provides instant information on the wavenumbers of the Rossby waves which maximize the flux. This new tool enables the quick determination of which modes are most influential in imparting fluid exchange, which in the long term will homogenize the tracer concentration between the eddy and the jet. The results are validated by computing backward- and forward-time finite-time Lyapunov exponent fields, and also stable and unstable manifolds; the intermingling of these entities defines the region of chaotic transport between the eddy and the jet. The relationship of all of these to the time-varying transport flux between the eddy and the jet is carefully elucidated. The flux quantification presented here works for general time-dependence, whether or not lobes (intersection regions between stable and unstable manifolds) are present in the mixing region, and is therefore also easily computable for wave packets consisting of infinitely many wavenumbers.
AnCo3, a New Member of the Emerging Family of Phage-Like Plasmids

ABSTRACT A phage-like plasmid isolated from a clinical isolate of Salmonella enterica serovar Derby has strong nucleotide sequence identity to the phage-like plasmids pSTM_phi isolated from Salmonella enterica serovar Typhimurium L495, AnCo1 and AnCo2 from Escherichia coli 243 and Escherichia coli 244, and the virulent Salmonella-specific SSU5 bacteriophage.
Human tracking driven activity recognition in video streams

In this paper we describe a method to visually recognize activities from video streams driven by a robust tracking algorithm. The tracking algorithm uses object flow as a motion model that estimates the displacement and the direction of objects in imagery streams; as observation model, object flow is complemented by a generative prior based on the Gaussian Process Latent Variable Model for increased robustness to visual alterations of the tracked object (human). We then use tracking results as input to drive the recognition of activities by hidden Markov models-based classifiers. We evaluate the performance of the examined approach under real-life activity recognition scenarios in visually complex environments characterized by lighting changes, occlusions and outliers.
N-Benzylthieno[3,2-d]pyrimidin-4-amine

The title compound, C13H11N3S, crystallizes with two independent molecules in the asymmetric unit. The two molecules are geometrically very similar and differ mainly in a spatial orientation of the benzene and thieno[3,2-d]pyrimidine ring systems [dihedral angles = 69.49 (4) and 79.05 (3)°]. The nine-membered thieno[3,2-d]pyrimidine moieties have a planar conformation (r.m.s. deviations = 0.020 and 0.012 Å). In the crystal, molecules are linked through N—H⋯N, N—H⋯C and C—H⋯π non-covalent contacts into chains along the c axis, while neighbouring chains are connected via C—H⋯N interactions.
