NOVEL SCAFFOLDS FOR TISSUE ENGINEERING DEVELOPED BY FLOCK TECHNOLOGY SUPPORT CHONDROGENESIS IN VITRO (2009)

Flock technology is well known from textile industry. Short fibres are applied vertically on a substrate, coated with a flocking adhesive. Until now this technology has not been used in the field of biomaterials although it offers the possibility to create anisotrophic matrices with a high compressive strength despite of high porosity. Matrices presently used in matrix assisted autologous chondrocyte implantation do not show any orientation of the embedded chondrocytes. However column orientation and anisotropic direction of embedded cells and collagen fibers are thought to be necessary for proper cartilage matrix biomechanics. Combination of matrices as a guiding structure and chondrogenically differentiated mesenchymal stem cells (MSC) could offer new possibilities in the treatment of cartilage defects. Our aim was to evaluate whether anisotropic scaffolds are capable to support a cellular cartilaginous phenotype in vitro.

Electrostatically flocked matrices consisted of a collagen substrate, gelatine as adhesive and polyamide flock fibres. Chondrogenic cells and MSC were embedded in the scaffolds. Adherence, vitality and proliferation was assessed using confocal laser-scan microscopy (cLSM). Chondrogenic induction was performed in the presence of TGF-beta 3. Accumulation of proteoglycans was quantified by alcian-blue stain and collagen type II synthesis after extraction of the newly synthesized matrix.

cLSM showed proliferation of embedded MSC as evidenced by DAPI/Phalloidin stain. Vitality of embedded cells remained high over time. Articular chondrocytes and nucleus pulposus cells synthesized proteoglycans and collagen type II in the scaffolds. Also MSC embedded in the flock scaffolds differentiated and increased their chondrogenic phenotype over time.

Using cLSM and biochemical analyses we demonstrated that cells adhered and proliferated well in the new scaffolds. Furthermore we showed that the scaffolds are capable to support induction and maintenance of the chondrogenic phenotype. We conclude that flocking technology is suitable for fabrication of scaffolds for cell cultivation and cartilage tissue engineering.
Transmission of Parentally Shared Human Leukocyte Antigen Alleles and the Risk of Preterm Delivery (2004)

Our findings provide evidence that the transmission of parentally shared HLA alleles may be an underlying mechanism for preterm delivery.
Doping of group III nitrides (1998)

Recent advances in the understanding of the origin of the notorious residual n-type conductivity in GaN and our new concept of co-doping for improved p-type conductivity in GaN are briefly reviewed. Our experimental data reveal that O from residual H2O, which substitutes N on lattice sites, is the origin for the observed n-type conductivity. Co-doping with Be and O to form donor-accepted pairs in GaN results in a strongly improved p-type conductivity at room temperature due to a substantial enhancement of the hole mobility. This concept has been independently confirmed by theoretical calculations.
Beyond the distinction between public and private: hybrid welfare production in German old-age security (2006)

"Normally, when pension schemes are described, classified and compared, the categories of "public" and "private" are of primary importance. However, the distinction between "public" and "private" in the context of old-age security has recently been questioned for two reasons. First, most pension schemes can not unambiguously be classified as either "public" or "private". Consequently, the idea of an institutional welfare mix and the well-known pillar-metaphor with its clear-cut division between "public pillars" and "private pillars" are obviously too simplistic to convey the empirical diversity in old-age security. And second, recent pension reforms in Western-European welfare states have intensified the state regulation of what is conventionally called private pensions. The pension reform of 2001 in Germany is a good example of such public policy on "private" pensions and its consequences: Tax-financed subsidies for and regulation of occupational pensions and personal saving blur both the distinction between occupational and personal pensions as well as the distinction between "public" and "private". The emerging pension schemes are not only public-private mixes, but are genuinely hybrid. Applying the distinction between ‘public’ and ‘private’ to these schemes would be a serious misinterpretation of their essence and an underestimation of their complexity. Arguments about whether a particular scheme is predominantly "public" or "private" are ultimately political conflicts about the realm and extension of the state. This paper therefore pleads to leave the distinction between "public" and "private" to the political debate. New concepts and terminology are needed for the social scientific analysis of old-age security." (author's abstract)
Using an Ion Sink to Extract Microbial Phosphorus from Soil (1999)

Two ion sinks (FeO‐coated paper and anion exchange resin membrane) were tested to improve accuracy and precision in analysis of microbial P (P m ) in soil biomass. We used a noncarcinogenic biocide, hexanol. Ion‐sink extracted FeO‐P m [P m(FeO) ] and resin‐P m [P m(Res) ] were compared with bicarbonate extracted P m [P m(Bic) ]. Fractional recovery of P m (K p ) was determined with 50 μg P m from five different organisms, first, from preparations without soil, giving K p of 0.49 for P m(Bic) , 0.63 for P m(FeO) , and 0.66 for P m(Res) , and second, from soil‐organism mixes, giving K p of 0.36 for P m(Bic) , 0.49 for P m(FeO) , and 0.52 for P m(Res) This indicated ion sinks can improve accuracy of P m recovery. We tested 18 Kansas soils with three different levels of C + N substrates to provide varying levels of microbial activity. For unamended soils, P m values (mg kg −1 ) were 5.9 for P m(Bic) , 8.2 for P m(FeO) , and 6.3 for P m(Res) Corresponding values in soils with low levels of C + N amendments were 6.0 for P m(Bic) , 18.2 for P m(FeO) , and 18.7 for P m(Res) In soils with high levels of C + N amendments plus alfalfa ( Medicago sativa L.), corresponding values were 12.7 for P m(Bic) , 30.9 for P m(FeO) , and 37.3 for P m(Res) Above 10.0 mg kg −1 , P m(FeO) and P m(Res) were at least twice as much as P m(Bic) In addition, P m(FeO) and P m(Res) both had lower CVs than P m(Bic) , indicating greater precision by the ion‐sink methods.
The Toxicology of some Fluoro-Organic Compounds. (1961)

Abstract : Fluorocompounds of ethylene represent an extremely promising raw material for the polymerization plastics industry. The unique polymerization properties of fluoro-olefins provide a new group of plastics - fluoroplastics - whose economic significance can hardly be exaggerated. There exists the belief among some that the toxicity of fluorohydrocarbons depends on the number of hydrogen atoms replaced by fluorine. According to this view, fluorine-saturation of the organic molecule leads to a reduction in its biological activity. This is why tetrafluoroethylene, in which four hydrogen atoms are replaced by fluorine, is considered to be a nontoxic or low-toxicity compound. However, one need only compare the concentrations of vinyl fluoride, vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene required to produce a toxic effect in white rats - to question the correctness of this view.

Tri-layer silicon nitride-on-silicon photonic platform for ultra-low-loss crossings and interlayer transitions (2017)

We present a three-layer silicon nitride on silicon platform for constructing very large photonic integrated circuits. Efficient interlayer transitions are enabled by the close spacing between adjacent layers, while ultra-low-loss crossings are enabled by the large spacing between the topmost and bottommost layers. We demonstrate interlayer taper transitions with losses < 0.15 dB for wavelengths spanning from 1480 nm to 1620 nm. Our overpass waveguide crossings exhibit insertion loss < 2.1 mdB and crosstalk below -56 dB in the wavelength range between 1480 nm and 1620 nm with losses as low as 0.28 mdB. Our platform architecture is suited to meet the demands of large-scale photonic circuits which contain hundreds of crossings.

Patient Blood Management and Transfusion (2009)

In Reply:— We thank Dr. de Saint Maurice et al. for their comments regarding our editorial view1and share their concerns over perioperative deaths as a result of inadequate blood management. We could not agree more with their view that not measuring the hemoglobin concentration consecutively during major hemorrhage is substandard care, as is not treating severe hypovolemia or hypotension in such situations.This is what patient blood management is all about; patient blood management is not “just say no to blood transfusions.” Patient blood management is based on three pillars: Detecting and treating preoperative anemia, reducing the loss of red blood cells perioperatively, and optimizing the treatment of anemia. Red blood cell transfusions may be administered if all other options have been used and the patient starts showing signs of inadequate oxygenation. Of course, the quick correction of hypovolemia, hypotension, tachycardia, and arrhythmia is an integral part of patient blood management.It is of utmost importance not to confound the momentary helpful effect of red blood cell transfusion on hypotension and hypovolemia with an outcome benefit. Red blood cell transfusions are indisputably associated with an increase in mortality,2,3major adverse cardiac and noncardiac outcome,4acute lung injury,5nosocomial infection,5tumor growth,6duration of hospitalization, and cost.7Therefore, there is an urgent need for change, and the Governments of Western Australia and the Canton of Zurich, Switzerland, are to be congratulated again for taking the lead in sustainably implementing patient blood management and thereby improving patient outcome.*University Hospital Zürich, Zürich, Switzerland. donat.spahn@usz.ch
440 A Comparative Study on Flavor and Nutritional Attributes of `BetaSweet' Maroon Carrot (Daucus carota L.) (1999)

A new designer carrot, `BetaSweet', with high levels of anthocyanin, betacarotene, and crispy texture was developed by the Vegetable Improvement Center at Texas A&amp;M Univ. The new carrot contained low levels of low-volatile terpenoids, responsible for the harsh flavor in carrots and high levels of reducing sugars. Carotenoid content increased with carrot maturity and stabilize at 120 days after sowing for orange and maroon genotypes; however, the maroon genotype was 35% higher than the orange cultivar. Anthocyanin, a cancer preventive compound and not detected in ordinary orange carrots, is present in `BetaSweet' maroon carrot with 89.8 mg·100 g -1 of fresh weight. High percentage of soluble solids and succulence in the maroon cultivar seemed to contribute to the favored sweetness perception by consumers. A consumer taste panel showed a significant difference between orange and maroon genotype for sweetness, texture, and overall carrot flavor.

Improving object learning through manipulation and robot self-identification (2013)

We present a developmental approach that allows a humanoid robot to continuously and incrementally learn entities through interaction with a human partner in a first stage before categorizing these entities into objects, humans or robot parts and using this knowledge to improve objects models by manipulation in a second stage. This approach does not require prior knowledge about the appearance of the robot, the human or the objects. The proposed perceptual system segments the visual space into proto-objects, analyses their appearance, and associates them with physical entities. Entities are then classified based on the mutual information with proprioception and on motion statistics. The ability to discriminate between the robot's parts and a manipulated object then allows to update the object model with newly observed object views during manipulation. We evaluate our system on an iCub robot, showing the independence of the self-identification method on the robot's hands appearances by wearing different colored gloves. The interactive object learning using self-identification shows an improvement in the objects recognition accuracy with respect to learning through observation only.
Expression of recombinant GFP-actin fusion protein in the methylotrophic yeast Pichia pastoris (2003)

The integrative vector pPIC3 for the yeast Pichia pastoris and a cDNA fragment encoding a fusion protein consisting of green fluorescent protein (GFP) and actin 5C of the fruit fly Drosophila melanogaster were used to construct a pPIC3-GFP-actin 5C expression plasmid. The P. pastoris host strain GS115 was transformed with the pPIC3-GFP-actin 5C carrying HIS4 as a selective marker. The transformants were selected on a histidine-deficient medium, and were shown to contain the gene of GFP-actin 5C fusion protein. Expression was induced by cultivation of the transformant cells in a methanol-containing medium. Production of the fusion protein in the yeast was detected by the bright green fluorescence of the GFP tag. The pattern of yeast cytoskeleton labeling by the fusion indicated proper folding and functioning of GFP-actin 5C in a heterologous system in vivo. After cell destruction, purification of GFP-actin 5C was performed by DNase I-Sepharose. Efficient binding of the chimera to the DNase I indicated nativity of the actin 5C fusion in vitro. SDS electrophoresis and further Western blot confirmed the purified protein to exhibit the expected molecular mass of about 70 kDa. The recombinant GFP-actin 5C was used to produce polyclonal antibodies, which had not been reported so far but are extremely needed for immuno-labeling and isolation of wild-type and mutant forms of actin 5C.
A multiple model adaptive dual control algorithm for stochastic systems with unknown parameters (1980)

An adaptive dual control algorithm is presented for linear stochastic systems with constant but unknown parameters. The system parameters are assumed to belong to a finite set on which a prior probability distribution is available. The tool used to derive the algorithm is preposterior analysis: a probabilistic characterization of the future adaptation process allows the controller to take advantage of the dual effect. The resulting actively adaptive control called model adaptive dual (MAD) control is compared to two passively adaptive control algorithms-the heuristic certainty equivalence (HCE) and the Deshpande-Upadhyay-Lainiotis (DUL) model-weighted controllers. An analysis technique developed for the comparison of different controllers is used to show statistically significant improvement in the performance of the MAD algorithm over those of the HCE and DUL.
Assessment of Risk Factors and Biomarkers Associated With Risk of Cardiovascular Disease Among Women Consuming a Mediterranean Diet (2018)

A unified GLTF/X3D extension to bring physically-based rendering to the web (2016)

We present a unified material description and transmission format for real-time, physically-based shading. Our format is general enough to be used consistently across multiple rendering systems and platforms, covering a wide range of applications from desktop to Web. Furthermore, our format's expressiveness allows to represent a wide variety of real-world materials. First, we define a common parameter set for physically-based shading in modern, real-time 3D graphics systems. We then demonstrate its applicability for several types of materials on different rendering systems. Finally, we propose a transmission format, in the form of extensions for the glTF and X3D standards.
Phosphorylation by Cyclin B-Cdk Underlies Release of Mitotic Exit Activator Cdc14 from the Nucleolus (2004)

Budding yeast protein phosphatase Cdc14 is sequestered in the nucleolus in an inactive state during interphase by the anchor protein Net1. Upon entry into anaphase, the Cdc14 early anaphase release (FEAR) network initiates dispersal of active Cdc14 throughout the cell. We report that the FEARnetwork promotes phosphorylation of Net1 by cyclin-dependent kinase (Cdk) complexed with cyclin B1 or cyclin B2. These phosphorylations appear to be required for FEAR and sustain the proper timing of late mitotic events. Thus, a regulatory circuit exists to ensure that the arbiter of the mitotic state, Cdk, sets in motion events that culminate in exit from mitosis.
A Robust Semantic Parser Designed for Spoken Dialog Sytems (2010)

This article describes a knowledge oriented semantic parser designed for spoken dialog systems. It merges some syntactic and semantic aspects into a single frame to get robust and efficient analyses. The knowledge is entirely described withing an XML formalism. The parser takes as input either a string of words (the 1-best word sequence) or a word-lattice coming from an ASR (Automatic Speech Recognition) system. The output is a semantic structure of concepts representing the meaning of the utterance. From an algorithmic point of view, the parser uses a chart principle implemented with the CLIPS system, a rule-based inference engine. The article presents some results obtained by performing an evaluation based on the MEDIA French corpus. The parser is distributed as an open-source tool.
Variable Reordering on the QMDD Representation of Quantum Circuits (2007)

In [1], a novel structure was discussed for representing the matrices that can be built from an n-variable r-valued reversible/quantum circuit. This structure, called a QMDD, takes on a form similar to that of a reduced-orderedbinary-decision-diagram (ROBDD). It is known that the order of variables used for developing an ROBDD from a binary logic circuit is relevant to the size and structure of that ROBDD [3]. This paper determines what effect, if any, variable order has on the QMDD structure and proposes a simple heuristic for choosing a ‘good’ variable order.

Nice is Different than Good: Longitudinal Communicative Effects of Realistic and Cartoon Avatars in Real Mixed Reality Work Meetings (2022)

We report a within-subjects study of the effect of realistic and cartoon avatars on communication, task satisfaction, and perceived sense of presence in mixed reality meetings. For 2 − 3 weeks, six groups of co-workers (14 people) held a recurring real work meeting using Microsoft HoloLens2 devices. Each person embodied a personalised full-body avatar with a realistic face and another with a cartoon face. Half the groups started in the realistic condition and the other half started in the cartoon condition; all groups switched conditions half-way. Initial results show that, overall, participants found the realistic avatars’ nonverbal behaviour more appropriate for the interaction and more useful for understanding their colleagues compared to the cartoon one. Regarding the results over time, we identify different insights for cartoon and realistic avatars based on the type of avatar was embodied first. We discuss the implications of these results for mixed and virtual reality meetings.
