Loss modeling and optimization for monolithic implementation of the three-level buck converter (2013)

This paper presents parameter extraction based loss modeling to reduce the high-order design space for the three-level buck converter optimized for monolithic implementation. Loss models derived from simulation extracted parameters are presented to reduce model complexity while maintaining accurate loss predictions. The design space is reduced further by analysis of converter characteristics. An optimization approach is applied to select the inductor, the switching frequency, and the sizes of the power devices and the gate drive stages. The loss model and the optimization approach are validated for a 3.7-to-1.15 V, 4 MHz, 2 A converter through detailed circuit simulations in a 0.18 μm CMOS process.
Electromagnetic Shielding by MXene-Graphene-PVDF Composite with Hydrophobic, Lightweight and Flexible Graphene Coated Fabric (2018)

MXene and graphene based thin, flexible and low-density composite were prepared by cost effective spray coating and solvent casting method. The fabricated composite was characterized using Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray (EDX). The prepared composites showed hydrophobic nature with higher contact angle of 126°, -43 mN·m<sup>-1</sup> wetting energy, -116 mN·m<sup>-1</sup> spreading Coefficient and 30 mN·m<sup>-1</sup> lowest work of adhesion. The composites displayed excellent conductivity of 13.68 S·cm<sup>-1</sup> with 3.1 Ω·sq<sup>-1</sup> lowest sheet resistance. All the composites showed an outstanding thermal stability and constrain highest weight lost until 400 °C. The MXene-graphene foam exhibited excellent EMI shielding of 53.8 dB (99.999%) with reflection of 13.10 dB and absorption of 43.38 dB in 8⁻12.4 GHz. The single coated carbon fabric displayed outstanding absolute shielding effectiveness of 35,369.82 dB·cm²·g<sup>-1</sup>. The above results lead perspective applications such as aeronautics, radars, air travels, mobile phones, handy electronics and military applications.
Neuropilins are positive regulators of Hedgehog signal transduction (2011)

The Hedgehog (Hh) pathway is essential for vertebrate embryogenesis, and excessive Hh target gene activation can cause cancer in humans. Here we show that Neuropilin 1 (Nrp1) and Nrp2, transmembrane proteins with roles in axon guidance and vascular endothelial growth factor (VEGF) signaling, are important positive regulators of Hh signal transduction. Nrps are expressed at times and locations of active Hh signal transduction during mouse development. Using cell lines lacking key Hh pathway components, we show that Nrps mediate Hh transduction between activated Smoothened (Smo) protein and the negative regulator Suppressor of Fused (SuFu). Nrp1 transcription is induced by Hh signaling, and Nrp1 overexpression increases maximal Hh target gene activation, indicating the existence of a positive feedback circuit. The regulation of Hh signal transduction by Nrps is conserved between mammals and bony fish, as we show that morpholinos targeting the Nrp zebrafish ortholog nrp1a produce a specific and highly penetrant Hh pathway loss-of-function phenotype. These findings enhance our knowledge of Hh pathway regulation and provide evidence for a conserved nexus between Nrps and this important developmental signaling system.

Generation of Low-Energy High-Current Electron Beams in Plasma-Anode Electron Guns (2018)

This paper is a review of studies on the generation of low-energy high-current electron beams in electron guns with a plasma anode and an explosive-emission cathode. The problems related to the initiation of explosive electron emission under plasma and the formation and transport of high-current electron beams in plasma-filled systems are discussed consecutively. Considerable attention is given to the nonstationary effects that occur in the space charge layers of plasma. Emphasis is also placed on the problem of providing a uniform energy density distribution over the beam cross section, which is of critical importance in using electron beams of this type for surface treatment of materials. Examples of facilities based on low-energy high-current electron beam sources are presented and their applications in materials science and practice are discussed.
55 NUCLEUS CHANGES AND DEVELOPMENT OF PORCINE RECONSTRUCTED (NT) AND PARTHOGENETICALLY ACTIVATED (PA) EMBRYOS (2004)

Nuclear reprogramming is characterized by functional modification(s) of the transferred nucleus that allows it to direct normal embryo development with the potential to grow to term. The aim of our study was to investigate the process of nuclear changes in reconstructed and activated embryos as well as their developmental competence. All chemicals used were from Sigma Chemicals (St. Louis, MO, USA). Cumulus-oocyte complexes were aspirated from slaughterhouse ovaries of prepurbetal gilts and matured for 42 h in vitro. The cumulus cells were removed by adding in 1 mg mL -1 hyaluronidase in TLP-HEPES. For the NT experiment, oocytes with first polar body were cultured in 0.4 µg mL-1 demecolcine for 1 h. A protruding membrane was removed by micromanipulator and a single donor nucleus from fetal fibroblast was injected subzonally. Fusion was conducted immediately after transfer in 0.3 M mannitol, 0.5 mM HEPES, 0.1% PVA, and 0.1 mM MgCl2 in a fusion chamber with parallel electrodes set 1 mm apart using a singe DC pulse of 125 V mm-1 for 80 s. Activation was done 2–4 h after fusion in the same medium as fusion but with 0.1 mM CaCl2 added; embryos were cultured in 5 µg mL-1 cytochalasin B and 10 µg mL-1 cyclohexamide for 6 h. The embryos were cultured in glucose-free NCSU-37 containing 4 mg mL-1 BSA as basic medium supplemented with 0.17 mM sodium pyruvate and 2.73 mM sodium lactate from Days 0 to 2, and then in basic medium with 5.55 mM D-glucose from Days 2–6 (Kikuchi K et al. 2002 Biol. Reprod. 66, 1033–1041). Non-manipulated oocytes (PA) were electrically activated as stated above. For observing the changes of donor cells, some reconstructed oocytes were fixed 2 h after fusion, prior to activation, and some 12 h after activation in acetic acid:ethanol (1:3) and stained in 1% orcein. The activated oocytes were fixed at 12 h and stained as stated above. There were 47.5% (38/80) of reconstructed oocytes with premature chromosome condensation (PCC), and 23.7% (19/80) with nuclear swelling two hours after fusion. Pronuclear like formation 12 h after activation was 45% (27/60) and 83.3% (50/60) in NT and PA, respectively. The blastocyst rate was 8.3% (5/60) and 46% (69/150) for NT and PA, respectively. The results suggest that porcine oocyte cytoplasm can successfully reprogram somatic cell nuclei and support the development of NT embryos to the blastocyst stage.

Plasma Levels of Growth Hormone, Insulin and Plasma Protein-Bound Iodine in Finishing Cattle (1970)

Growth hormone, insulin and PBI were measured in plasma samples from 30 yearling steers fed finishing rations. Insulin and PBI were measured in samples from 24 yearling heifers. Feeding of finishing rations had no effect on concentration of plasma GH. Levels of plasma insulin gradually increased while the animals were fed finishing rations. Feeding stilbestrol increased plasma GH (P<.01) in steers, increased plasma insulin in steers and heifers and had no effect on PBI. The cattle fed stilbestrol gained more weight (P<.05) and had larger pituitary glands (P<.01) than did control animals. Correlations between levels of plasma hormones and weight gain tended to be positive with insulin and negative with GH.
Word semantics for information retrieval: moving one step closer to the Semantic Web (2002)

The goal of the Semantic Web is to create a new form of Web content meaningful to computers. The Semantic Web aims to provide greater functionality, via intelligent tools such as information extractors, brokers, reasoning services or question answering systems. Semantics can be addressed at several levels. In this paper, we focus on the lowest level-word semantics on which other higher levels such as concept, paragraph, or document levels can be based upon. This model, which we call Word Semantics (WS), does not include the rich set of tags proposed by the XML/RDF standards. Nevertheless, this simpler WS format comes with a big advantage: it is possible with existing technologies and resources. Practically, this new model relies on understanding word meanings, identifying important named entities such as person, organization and others, and linking all this information via an external general purpose ontology, namely WordNet. With these features, we regard the WS model as a short but strong step toward the long term goal of a Semantic Web.
2.2 Wissenschaftlicher Datenmarkt (2021)

Anhand von Forschungsdatenrepositorien (FDR) zur Speicherung, Bereitstellung und Nachnutzung digitaler Daten aus und für die Wissenschaft werden verschiedene Aspekte des Austauschs von Forschungsdaten beleuchtet, um so eine empirisch- näherungsweise Beschreibung des wissenschaftlichen Datenmarktes zu erhalten. Der wissenschaftliche Datenmarkt ist historisch gesehen von einem hohen Grad an Heterogenität und Dynamik geprägt und wenig durch Standards und fachbereichsübergreifende Best-Practices strukturiert. Diese Eigenschaften spiegeln sich in der gegenwärtigen digitalen Transformation der Wissenschaften wider, die einerseits diese Merkmale sichtbarer werden lässt und befördert, andererseits auch die immensen Potentiale von Standardisierung, Nachhaltigkeit, Transparenz und Reproduzierbarkeit über Fachgebiete hinweg aufzeigt und greifbar werden lässt.
How Would You Say It? Eliciting Lexically Diverse Dialogue for Supervised Semantic Parsing (2017)

Building dialogue interfaces for realworld scenarios often entails training semantic parsers starting from zero examples. How can we build datasets that better capture the variety of ways users might phrase their queries, and what queries are actually realistic? Wang et al. (2015) proposed a method to build semantic parsing datasets by generating canonical utterances using a grammar and having crowdworkers paraphrase them into natural wording. A limitation of this approach is that it induces bias towards using similar language as the canonical utterances. In this work, we present a methodology that elicits meaningful and lexically diverse queries from users for semantic parsing tasks. Starting from a seed lexicon and a generative grammar, we pair logical forms with mixed text-image representations and ask crowdworkers to paraphrase and confirm the plausibility of the queries that they generated. We use this method to build a semantic parsing dataset from scratch for a dialog agent in a smart-home simulation. We find evidence that this dataset, which we have named SMARTHOME, is demonstrably more lexically diverse and difficult to parse than existing domain-specific semantic parsing datasets.
THE ROLE OF IMMUNE CELLS AND CYTOKINES IN THE DEVELOPMENT OF PSORIASIS (2013)

филами. В результате миграции в роговом слое эпидермиса образуются скопления нейтрофилов, так называемые микро-абсцессы Munro. Нейтрофилы экспрессируют IL-17. В ко-личественном отношении нейтрофилы и IL-17-содержащие нейтрофилы превалируют над Th17-лимфоцитами [2]. Ней-трофилы синтезируют IL-1 β, IL-6, IL-8, IL-17 и TNF- α. В свою очередь IL-17A, IL-17F и TNF-α, синтезируемые нейтрофила-ми и другими клетками иммунной системы, индуцируют в кератиноцитах синтез IL-8, вызывающий приток нейтрофи-лов в эпидермис. В эпидермисе нейтрофилы находятся в тес-ном контакте с кератиноцитами, миелоидными дендритными клетками (ДК) и NK-клетками. Эти контакты существенно повышают устойчивость нейтрофилов к апоптозу.Макрофаги. В пораженной коже больных псориазом в 3 раза +повышено количество CD163-макрофагов. После лечения этанерцептом, антагонистом TNF-α, их количество возвращается к норме [3].

Use of the stapler in anterior resection for cancer of the rectosigmoid. (1983)

The circular stapling device was used for anterior resection in 61 of 88 patients who underwent curative surgery for rectosigmoid cancer. Use of the autosuture increased the success rate to 68.5% for this radical sphincter-saving procedure. In three-quarters of the patients the stapling end-to-end inverting colorectal anastomosis was created within 3 to 8 cm from the dentate line, where it is difficult or even impossible to perform anastamoses by the conventional manual technique. Anastomotic leakage (3.3%) and hemorrhage (4.9%), mild anastomotic stenosis (1.6%) and transitory anal incontinence (4.9%) were the main complications. There were no deaths in our series. The great safety of the stapling anastomosis and the low rate of anal incontinence may be explained by the preservation of an adequate blood supply and innervation of the rectal stump and its sphincter apparatus, as the stapling device needs only minimal mobilization of the bowel involved in the anastomosis. Restoring colorectal continuity after Hartmann's resection is a speedy, safe and simple procedure with the EEA (enteroenterostomy) stapler. Hartmann's operation may thus be considered the procedure of choice in emergency surgery for obstructed rectosigmoid cancer.
Test-based risk assessment and security certification proposal for the Internet of Things (2018)

This work provides a design of a certification methodology for IoT, paying attention to the test-based risk assessment phase to empower testers with the ability to assess security solutions for large-scale IoT deployments. The resulting approach is an instantiation of the Risk-based Security Assessment presented by ETSI based on the ISO 31000, and it is built on top of different technologies and approaches for security testing and risk assessment adapted to the IoT landscape. The proposed methodology is intended to be used for the different experiments that are proposed in the scope of the ARMOUR project for assessing the fulfilment of several security aspects. It is expected to be used as a baseline to build a new security certification and labelling approach for IoT devices.
LES/CMC Predictions of Spark Ignition Probability in a Liquid Fuelled Swirl Combustor (2013)

The Large Eddy Simulation / Conditional Moment Closure approach with closures for the spray terms appearing in the CMC equation and for the mixture fraction sub-grid variance has been used to predict ignition probability, Pign, for a swirling spray ame for which relevant experimental data are available. The localised spark was modelled as a small region where the conditionally averaged reactive scalars were kept constant for a short time. For each of 20 locations across the ow, Pign was estimated by launching 16 separate simulations from di erent coldow realisations and monitoring the ame evolution. The predicted large variability in ignition behaviour, the overall time for ame expansion, and the spatial distributions of Pign agree qualitatively well with the experiment. The failure of a ame kernel to grow is traced to high scalar dissipations in the spark neighbourhood, which in turn depends on the mixture fraction sub-grid variance model, showing that the spray a ects both quantities and that the corresponding models need further validation.

MULTI-POS - multi-technology positioning professionals training network (2014)

The global navigation market (products and services) is expected to grow to more than 160 billion EUR revenue by 2015 with significant growth being driven by mobile terminals. The pillars of the future wireless society will be the trustworthiness of the wireless positioning device and ecofriendliness of the transmission-reception process. These are triggered by the user needs, preferences and targeted applications, and by the type of the environment where navigation takes place. A link is still missing between these user needs/environment awareness (or application layer) and the physical layer where the wireless device is actually designed. The missing link can be created by cognitive approaches, borrowed on one hand from cognitive human behavior, and on the other hand from cognitive computing. Building a cognition stage between the application and physical layers will create a myriad of new possibilities for flexible location-based services and positioning-based applications, and possibly a new paradigm in wireless location research. MULTI-POS training network is bridging the gap between the lower technology layer and upper application layer involved in wireless mobile location. In addition, MULTI-POS will offer comprehensive training to young fellows in the broad field of wireless location, will create novel technologies and business models for the future location-enabled wireless devices, will promote the exchange of fellows in mixed academic-industrial R&D trajectories and in multiple European cultures, and will initiate an educational and research framework that unifies the currently fragmented research activities on technological and applications aspects of wireless navigation. There is strong involvement of industrial partners in the network to accomplish this.
