The cohort of the ammonia-oxidizing archaea (AOA) phylum Thaumarchaeota is a diverse, widespread and functionally important group microorganisms in many ecosystems. However, our understanding their biology still very rudimentary part because all available genome sequences this are from members Nitrosopumilus cluster. Here we report on complete sequence Candidatus Nitrososphaera gargensis obtained an enrichment culture, representing different evolutionary lineage AOA frequently found high...
PURPOSE: To prospectively assess the effect of including or excluding endocardial trabeculae in left ventricular (LV) measurements and reproducibility these at cine cardiovascular magnetic resonance (MR) imaging with true fast steady-state precession (FISP). MATERIALS AND METHODS: The study was approved by local ethics committee, each subject gave informed consent before participating. Twenty healthy subjects 20 consecutive patients underwent 1.5-T MR imaging. Seven to 12 short-axis views...
The recent observation by the IceCube neutrino observatory of an astrophysical flux neutrinos represents "first light" in nascent field astronomy. observed diffuse seems to suggest a much larger level hadronic activity non-thermal universe than previously thought and suggests rich discovery potential for observatory. This document presents vision substantial expansion current detector, IceCube-Gen2, including aim instrumenting $10\,\mathrm{km}^3$ volume clear glacial ice at South Pole...
Linked Data has emerged as a powerful way of interconnecting structured data on the Web. However, cross-linkage between sources is not extensive one would hope for. In this paper, we formalize task automatically creating "sameAs" links across in globally consistent manner. Our algorithm, presented multi-core well distributed version, achieves link generation by accounting for joint evidence match. Experiments confirm that our system scales beyond 100 million entities and delivers highly...
Roughly every third Wikipedia article contains an infobox - a table that displays important facts about the subject in attribute-value form. The schema of infobox, i.e., attributes can be expressed for concept, is defined by template. Often, authors do not specify all template attributes, resulting incomplete infoboxes. With iPopulator, we introduce system automatically populates infoboxes articles extracting attribute values from article's text. In contrast to prior work, iPopulator detects...
Abstract This article considers robust model predictive control (MPC) schemes for linear parameter varying (LPV) systems in which the time-varying is assumed to be measured online and exploited feedback. A closed-loop MPC with a parameter-dependent law proposed first. The reduces conservativeness of existing results static at cost higher computational burden. Furthermore, an scheme prediction horizon '1' deal case asymmetric constraints. Both approaches guarantee recursive feasibility...
Abstract Melt electrowriting (MEW) is a high‐resolution additive manufacturing technology that places unique constraints on the processing of thermally degradable polymers. With single nozzle, MEW operates at low throughput and in this study, medical‐grade poly(ε‐caprolactone) (PCL) heated for 25 d three different temperatures (75, 85, 95 °C), collecting daily samples. There an initial increase fiber diameter decrease jet speed over first 5 d, then process remains stable 75 85 °C groups....
Linked open data (LOD), as provided by a quickly growing number of sources constitutes wealth easily accessible information. However, this is not easy to understand. It usually set (RDF) triples, often enough in the form enormous files covering many domains. What more, has loose structure when it derived from end-user generated sources, such Wikipedia. Finally, quality actual also worrisome, because may be incomplete, poorly formatted, inconsistent, etc. To understand and profile linked...
Many government organizations publish a variety of data on the web to enable transparency, foster applications, and satisfy legal obligations. Data content, format, structure, quality vary widely, even in cases where is published using wide-spread linked principles. Yet within this their integration lies much value: We demonstrate GovWILD, web-based prototype that integrates cleanses Open Government at large scale. Apart from interface presents use case created dataset govwild.org, we...
Heterogeneous and dirty data is abundant. It stored under different, often opaque schemata, it represents identical real-world objects multiple times, causing duplicates, has missing values conflicting values. The Humboldt Merger (HumMer) a tool that allows ad-hoc, declarative fusion of such using simple extension to SQL.Guided by query against tables, HumMer proceeds in three fully automated steps: First, instance-based schema matching bridges schematic heterogeneity the tables aligning...
A new contactless device internal test technique is introduced based on a scanning force microscope enabling dynamic voltage contrast within passivated integrated circuits. spatial resolution below 500 nm and down to voltages of 0.2 V amplitude are achieved. For the first time static obtained with shown Potential limits this discussed.
Large amounts of graph-structured data are emerging from various avenues, ranging natural and life sciences to social semantic web communities. We address the problem discovering subgraphs entities that reflect latent topics in data. These structured meta-information providing further insights into The presented approach effectively detects such by exploiting only structure underlying graph, thus avoiding dependency on textual labels, which a scarce asset prevalent graph datasets. viability...
This paper presents an infinite horizon model predictive control (MPC) scheme for constrained linear parameter-varying systems. We assume that the time-varying parameter can be measured online and exploited feedback. The proposed method is based on a parameter-dependent law which obtained via repeated solution of convex optimization problem involving matrix inequalities (LMIs). Closed-loop stability guaranteed by feasibility LMIs at initial time. Compared to existing algorithms with static...
The synthesis of an alternating squaraine-naphthalene diimide donor-acceptor low band gap polymer (1.14-1.40 eV) as well its monomolecular analogue is presented. Spectroelectrochemistry experiments and transient absorption spectroscopy in the fs-time regime reveal ultrafast population a charge separated state for both monomer. Local excitation squaraine moiety followed by intermediate states, presumably transfer full separation, which occurs within ca. 2 ps. Charge recombination takes place...
Thermosetting polymers are widely used in electronic industry as encapsulants of devices. It is well known that properties and polymer-based composites like molding compounds highly dependent on conditions like: temperature, time, humidity, degree cure etc. These effects investigated extensively the past. Surprisingly, effect postcure thermal aging thermomechanical compound scarcely studied. Some studies devoted to this topic but not systematically carried out. The main conclusion previous...
An electronic device cannot perform its designed functions until it is packaged such that interconnected with the rest of system and protected. As an encapsulation material, thermosetting polymers are widely used. It well known properties polymer-based composites like molding compounds highly affected by influence temperature, relative humidity degree conversion. The effect above mentioned internal external circumstances investigated extensively in past. Surprisingly high temperature storage...

Warpage is a critical issue for QFN panel molding process. Much work done in the past to predict warpage of package during cooling down from temperature. However, until now, could not always be predicted well, even if viscoelastic behavior compound taken into account. It was example observed that velocity affected after down. Because this reason, mechanical investigated more detail. In research, properties are determined. turned out highly dependent on time and A complete model achieved by...
