Thermoluminescent Response of KMgF3:Yb Single-Crystals in Gamma Radiation Fields (1999)

The perovskite-like KMgF<inf>3</inf> shows, when properly doped, thermoluminescence (TL) characteristics that make this phosphor a good candidate for ionising radiation dosimetry. With the purpose of inspecting the dosimetric potentiality of such material, the thermoluminescence emission from irradiated samples of variously doped KMgF<inf>3</inf> in the form of single crystals has been investigated. The features displayed by fluoroperovskite doped with rare earth impurities are particularly promising, in particular Ce and Yb. The results obtained with KMgF<inf>3</inf>:Yb single crystals in particular are described. The TL emission relative to temperature was inspected by means of laboratory-made instrumentation, giving also the possibility of wavelength resolution. The TL emission shows a sharp peak at 410 nm, well centred in the wavelength range of the standard TLD readers; the emission intensity is one order higher than that of TLD-700 chips. The emission was inspected in the dose range from 2 mGy to 20 Gy.
Quantitative Evaluation of Rotaviral Antigenemia in Children with Acute Rotaviral Diarrhea (2006)

BackgroundRotaviral antigen and RNA have recently been identified in the serum of patients with rotaviral gastroenteritis, but the roles they play in disease remains undetermined MethodsRotaviral antigen and RNA were quantified by enzyme-linked immunosorbant assay and by quantitative reverse-transcription polymerase chain reaction in stool and serum specimens from children with rotaviral diarrhea (n=102), children with nonrotaviral diarrhea (n=40), and nondiarrheal control children (n=30) ResultsRotaviral antigenemia was detected in 64%, 3%, and 0% of the children with rotaviral diarrhea, the children with nonrotaviral diarrhea, and the nondiarrheal control children, respectively. The level of rotaviral antigen in serum was ∼2×102–fold lower than that in stool, and a moderate correlation was observed between the 2 levels. Rotaviral RNA was detected in 93% of the antigen-positive serum specimens. The median number of RNA copies in serum was ∼1×105-fold lower than that in stool, and no correlation was observed between the 2 levels. Serum levels of both antigen and RNA were inversely associated with baseline titers of rotaviral serum immunoglobulin G (P<.01). Antigenemia was also associated with G1 serotype ConclusionsRotaviral antigenemia and viremia were common in children with rotaviral diarrhea, but antigen and RNA levels in serum were substantially lower than those in stool. Antigenemia was associated with infection with G1 strains and with low baseline titers of rotaviral serum antibody
Real-Time Implementation of Change Detection for Automated Video Surveillance System (2013)

Change detection is one of the several important problems in the design of any automated video surveillance system. Appropriate selection of frames of significant changes can minimize the communication and processing overheads for such systems. This research presents the design of a VLSI architecture for change detection in a video sequence and its implementation on Virtex-IIPro FPGA platform. Clustering-based scheme is used for change detection. The proposed system is designed to meet the real-time requirements of video surveillance applications. It robustly detects the changes in a video stream in real time at 25 frames per second (fps) in gray scale CIF size video.
Identification of Microbial Products from Dibenzothiophene and Its Proposed Oxidation Pathway (1973)

One of the microbial products produced from dibenzothiophene by Pseudomonas abikonensis or P. jianii was identified as a new substance, trans-4[2-(3-hydroxy)-thianaphthenyl]-2-oxo-3-butenoic acid, and the other as its hemiacetal form. From the structures of the products, an oxidation pathway of dibenzothiophene was suggested. Moreover, the culture broth and the isolated products were examined for plant growth activities on rice plants.
Label‐free analysis of mononuclear human blood cells in microfluidic flow by coherent imaging tools (2016)

The investigation of the physical properties of peripheral blood mononuclear cells (PBMC) is of great relevance, as they play a key role in regulating human body health. Here we report the possibility to characterize human PBMC in their physiological conditions in a microfluidic-based measurement system. A viscoelastic polymer solution is adopted for 3D alignment of individual cells inflow. An optical signature (OS) acquisition of each flowing cell is performed using a wide angle light scattering apparatus. Besides, a quantitative phase imaging (QPI) holographic system is employed with the aim (i) to check the position in flow of individual cells using a holographic 3D cell tracking method; and (ii) to estimate their 3D morphometric features, such as their refractive index (RI). Results obtained by combining OS and QPI have been compared with literature values, showing good agreement. The results confirm the possibility to obtain sub-micrometric details of physical cell properties in microfluidic flow, avoiding chemical staining or fluorescent labelling.
Flight–crash events in turbulence (2014)

The statistical properties of turbulence differ in an essential way from those of systems in or near thermal equilibrium because of the flux of energy between vastly different scales at which energy is supplied and at which it is dissipated. We elucidate this difference by studying experimentally and numerically the fluctuations of the energy of a small fluid particle moving in a turbulent fluid. We demonstrate how the fundamental property of detailed balance is broken, so that the probabilities of forward and backward transitions are not equal for turbulence. In physical terms, we found that in a large set of flow configurations, fluid elements decelerate faster than accelerate, a feature known all too well from driving in dense traffic. The statistical signature of rare "flight-crash" events, associated with fast particle deceleration, provides a way to quantify irreversibility in a turbulent flow. Namely, we find that the third moment of the power fluctuations along a trajectory, nondimensionalized by the energy flux, displays a remarkable power law as a function of the Reynolds number, both in two and in three spatial dimensions. This establishes a relation between the irreversibility of the system and the range of active scales. We speculate that the breakdown of the detailed balance characterized here is a general feature of other systems very far from equilibrium, displaying a wide range of spatial scales.
HLA-DO Modulates the Diversity of the MHC-II Self-peptidome (2018)

Presentation of antigenic peptides on MHC-II molecules is essential for tolerance to self and for initiation of immune responses against foreign antigens. DO (HLA-DO in humans, H2-O in mice) is a nonclassical MHC-II protein that has been implicated in control of autoimmunity and regulation of neutralizing antibody responses to viruses. These effects likely are related to a role of DO in selecting MHC-II epitopes, but previous studies examining the effect of DO on presentation of selected CD4 T cell epitopes have been contradictory. To understand how DO modulates MHC-II antigen presentation, we characterized the full spectrum of peptides presented by MHC-II molecules expressed by DO-sufficient and DO-deficient antigen-presenting cells <i>in vivo</i> and <i>in vitro</i> using quantitative mass spectrometry approaches. We found that DO controlled the diversity of the presented peptide repertoire, with a subset of peptides presented only when DO was expressed. Antigen-presenting cells express another nonclassical MHC-II protein, DM, which acts as a peptide editor by preferentially catalyzing the exchange of less stable MHC-II peptide complexes, and which is inhibited when bound to DO. Peptides presented uniquely in the presence of DO were sensitive to DM-mediated exchange, suggesting that decreased DM editing was responsible for the increased diversity. DO-deficient mice mounted CD4 T cell responses against wild-type antigen-presenting cells, but not vice versa, indicating that DO-dependent alterations in the MHC-II peptidome could be recognized by circulating T cells. These data suggest that cell-specific and regulated expression of HLA-DO serves to fine-tune MHC-II peptidomes, in order to enhance self-tolerance to a wide spectrum of epitopes while allowing focused presentation of immunodominant epitopes during an immune response.
Facet protection of (AlGa)As lasers using SiO2 sputter deposition (1979)

Sputter-deposited SiO2 films on (AlGa)As DH laser facets were found by chemical erosion tests and Auger spectroscopy to have strong adhesion and an abrupt film-facet interface profile. Half-wave coatings by sputtering allowed stable long-term operation of lasers over several thousand hours at 10–20-mW (0.7–1.2 mW/μm) power levels at room temperature, almost without change from the initial value of threshold current and optical power.
Thrombin-Induced Platelet Microbicidal Protein Susceptibility Phenotype Influences the Outcome of Oxacillin Prophylaxis and Therapy of Experimental <i>Staphylococcus aureus</i> Endocarditis (2000)

We previously showed that in vitro susceptibility profiles of Staphylococcus aureus to thrombin-induced platelet microbicidal protein 1 (tPMP-1) impacted the outcome of vancomycin treatment in experimental infective endocarditis. In this same model, treatment with oxacillin (a more rapid staphylocidal agent than vancomycin) enhanced the clearance of both tPMP-1-susceptible and -resistant cells from vegetations. The extent of clearance was greater for tPMP-1-susceptible cells.
Invasiveness of LiTaO/sub 3/ and GaAs probes in external E-O sampling (1993)

Disturbances of signals on a coplanar waveguide (CPW) induced by the presence of LiTaO/sub 3/ and GaAs electrooptic probes in external electrooptic (EO) sampling have been simulated and compared quantitatively. The finite-difference-time-domain method is used to simulate the full wave field around a coplanar waveguide on a GaAs substrate in an external EO sampling configuration. The results indicate that the induced signal disturbance, or invasiveness, of a LiTaO/sub 3/ probe is almost ten times that of a GaAs probe in terms of the magnitude of S/sub 11/, but that LiTaO/sub 3/ yields about two times the EO response for a given S/sub 11/ and optical probing wavelength. The transparency of LiTaO/sub 3/ to shorter wavelengths, however, allows an even higher sensitivity for this material relative to GaAs. The results suggest that these probes do not exhibit significant invasiveness (magnitude of S/sub 11/ smaller than -40 dB), if they are removed from contact by the distance of CPWs center conductor width.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Raman spectroscopy evidence of strong spin-phonon coupling in epitaxial thin films of the double perovskite La2NiMnO6 (2007)

The Raman spectra of epitaxial thin films of La2NiMnO6 on (001)-oriented LaAlO3 substrates have been measured in several exact scattering configurations between 12 and 773K. The evolution of the spectra with increasing temperature is consistent with a transition from the monoclinic P121∕n1 to rhombohedral R3¯ structure. The spin-phonon coupling results in significant softening of the phonon mode involving stretching vibrations of the (Ni∕Mn)O6 octahedra. The anomalous softening extends above TC=275K, indicating the presence of short range ordering up to 400K.
Mitochondrial targeted peptides preserve mitochondrial organization and decrease reversible myocardial changes in early swine metabolic syndrome (2017)

Disorganization of cardiomyocyte cytoskeletal-mitochondria-SR network is associated with cardiac reversible changes in early MetS, preceding overt cardiac dysfunction. These findings may introduce novel therapeutic targets for blunting cardiac damage in early MetS.
Subcellular Localization of Cyclic Nucleotide Phosphodiesterase Type 10A Variants, and Alteration of the Localization by cAMP-dependent Protein Kinase-dependent Phosphorylation (2004)

Our previous studies have suggested that two phosphodiesterase type 10A (PDE10A) variants, PDE10A1 and PDE10A2 transcripts, are mainly expressed in humans and that PDE10A2 and PDE10A3 transcripts are major variants in rats. In the present study, immunoblot analysis demonstrated that PDE10A proteins, especially PDE10A2, are more abundant in membrane fractions than in cytosolic fractions of rat striatum. Recombinant PDE10A1 and PDE10A3 were produced only in cytosolic fractions of transfected PC12h cells. By contrast, recombinant PDE10A2 was present mainly in membrane fractions. This finding agreed well with the result of subcellular fractionation of PDE10A in rat striatum. Immunocytochemical analysis showed that PDE10A2 was localized in the Golgi apparatus of transfected PC12h cells. PDE10A2 was phosphorylated by cAMP-dependent protein kinase (PKA) at Thr16. Interestingly, recombinant protein of wild-type PDE10A2, but not PDE10A2 mutant with an Ala replacement at Thr16, was distributed to cytosolic fractions by co-transfection with a plasmid encoding the catalytic subunit of PKA. A PDE10A2 mutant with Glu substitution at Thr16, which can be a mimic of phosphorylation, was localized in the cytosolic fractions of transfected PC12h cells. These observations implied that phosphorylation of PDE10A2 at Thr16 by PKA caused alteration of subcellular localization of PDE10A2 from the Golgi apparatus to cytosol. It is hypothesized that cAMP signaling in the Golgi area and the cytosol in neurons is controlled through alteration of subcellular localization of PDE10A brought by activation of PKA in response to intracellular elevations of cAMP.

An algorithm for the representation and computation of supermolecular surfaces and volumes (1989)

Abstract An algorithm for the computation and representation of van der Waals surfaces and volumes of supermolecules (several overlapping molecules) by a set of grid points originating from an equidistant lattice is described in detail. The grid points in this set belong either to the “outer” surface of the van der Waals body or to a layer just below that outer surface. By means of this double layer (outer and inner) it is possible to represent the volume via the surface without referring to grid points lying inside the body. The algorithm is based on the octree concept, which means that the final relevant lattice points are derived by the successive refinement of an initial coarse lattice. The main features of the algorithm are the automatic elimination of inner atoms irrelevant for the surface definition and the association of any surface point with only those atoms which define the surface in the vicinity of these points. The most remarkable consequence of these features is that the amount of computation is almost independent of the number of atoms in the supermolecule. The algorithm can be used in solving problems arising in drug design, protein folding, molecular graphics, etc.
Towards efficient virtual network embedding across multiple network domains (2014)

Network virtualization provides a promising way to run multiple virtual networks (VNs) simultaneously on a shared infrastructure. It is critical to efficiently map VNs onto substrate resources, which is known as the VN embedding problem. Most existing studies restrict this problem in a single substrate domain, whereas the VN embedding process across multiple domains (i.e., inter-domain embedding) is more practical, because a single domain rarely controls an entire end-to-end path. Since infrastructure providers (InPs) are usually reluctant to expose their substrate information, the inter-domain embedding is more sophisticated than the intra-domain case. In this paper, we develop an efficient solution to facilitate the inter-domain embedding problem. We start with extending the current business roles by employing a broker-like role, virtual network provider (VNP), to make centralized embedding decisions. Accordingly, a reasonable information sharing scheme is proposed to provide VNP with partial substrate information meanwhile keeping InPs' confidential information. Then we formulate the embedding problem as an integer programming problem. By relaxing integer constraints, we devise an inter-domain embedding algorithm to handle online VN requests in polynomial time. Simulation results show that our solution outperforms other counterparts and achieves 80%-90% of the benchmarks in an ideal scenario where VNP has complete knowledge of all substrate information.
Discovering the hidden structure of house prices with a non-parametric latent manifold model (2007)

In many regression problems, the variable to be predicted depends not only on a sample-specific feature vector, but also on an unknown (latent) manifold that must satisfy known constraints. An example is house prices, which depend on the characteristics of the house, and on the desirability of the neighborhood, which is not directly measurable. The proposed method comprises two trainable components. The first one is a parametric model that predicts the "intrinsic" price of the house from its description. The second one is a smooth, non-parametric model of the latent "desirability" manifold. The predicted price of a house is the product of its intrinsic price and desirability. The two components are trained simultaneously using a deterministic form of the EM algorithm. The model was trained on a large dataset of houses from Los Angeles county. It produces better predictions than pure parametric and non-parametric models. It also produces useful estimates of the desirability surface at each location.
Strobilurins F, G and H, three new antifungal metabolites from Bolinea lutea. I. Fermentation, isolation and biological activity. (1990)

Three new strobilurins F, G and H, antibiotics with antifungal activity, were isolated from cultures of Bolinea lutea Sacc. These new compounds differ from previously described analogs in their aromatic substitution. An HPLC method allows complete separation of all the components.
Synthesen in der Vitamin‐A‐Reihe (1960)

Abstract Als der Verfasser vor fast 8 Jahren von dem damaligen Leiter der Forschung der Badischen Anilin‐ & Soda‐Fabrik, Prof. Dr. W. Reppe , den Auftrag erhielt, eine neue Vitamin‐A‐Synthese zu entwickeln, lag eine Fülle meist nicht zum Ziel führender Arbeiten auf diesem Gebiet vor und die ausgezeichnete, technische Synthese des Vitamin A von O. Isler schien die einzige brauchbare zu bleiben. Ohne neue präparative Erkenntnisse wäre es, zumindest auf neuen Pfaden, nicht möglich gewesen, die Aufgabe zu bewältigen. Erst eine neue Reaktion, die Wittigs che Olefinsynthese, gab das Werkzeug für Arbeiten, in deren Verlauf zahlreiche neue Synthesen des Vitamins A und seiner biologisch wirksamen Derivate gefunden wurden und die mit der Ausarbeitung eines technischen Verfahrens zur Darstellung des Vitamins A einen vorläufigen Abschluß erreicht haben.

[Determination of the sensitivity of NAG-Vibrio to antibiotics by the methods of serial dilution in agar and agar diffusion]. (1982)

The methods of serial dilutions and agar diffusion in medium AGV were used in the study on sensitivity of 200 NAG-vibrio strains to 10 antibiotics. The regression equations showing the relation between the MIC log2 and the diameter of the zones of the vibrio growth inhibition around the standard discs with the antibiotics were estimated. An evaluation table was developed for semiquantitative interpretation of the diameters of the inhibition zones of the vibrio growth when the agar diffusion method was used. A possibility of rapid estimation of the results in determination of the vibrio sensitivity to antibiotics with the methods of serial dilutions and agar diffusion is shown.
