Correlation properties of large and small-scale parameters from multicell channel measurements (2009)

Based on two multicell measurement campaigns in Berlin and Dresden, correlation properties for channel parameters to different sites and to adjacent sectors of the same site are investigated. Results indicate that the assumptions in the widely used 3GPP spatial channel model (SCM) form an upper bound for the multicell correlations compared to our measurements. If the SCM is used to evaluate the performance of novel cooperative base station techniques, simulation results regarding the throughput can be considered as a lower bound for the capacity achievable in our measurement scenarios.
Identity Preservation of Agricultural Commodities (2002)

Identity preservation (IP) is a system of production, handling, and marketing practices that maintain the integrity of commodities. Crop varieties with unique traits benefit from IP programs that can capture their added value in markets.
Impact of Winding Layer Number and Magnet Type on Synchronous Surface PM Machines Designed for Wide Constant-Power Speed Range Operation (2008)

This paper thoroughly investigates the impact of the winding layer number and the choice of magnet type on the performance characteristics of surface permanent magnet (SPM) machines with fractional slot concentrated windings designed for wide speed ranges of constant-power operation. This is accomplished by carefully examining the performance characteristics of three different SPM machines designed for the same set of performance requirements drawn from an automotive direct-drive starter/alternator application. These results show that double-layer stator windings yield lower torque ripple and magnet eddy current losses than do single-layer windings, but can contribute to a lower overload torque capability. Although the adoption of sintered magnets leads to the highest machine torque density, bonded magnets result in a significant reduction of the magnet losses because of their much higher value of resistivity.
A methodology for preparing nanostructured biomolecular interfaces with high enzymatic activity (2011)

The development of a novel method for functionalizing nanopatterned surfaces with catalytically active proteins is reported. This method involves using dip-pen nanolithography (DPN) and polymer pen lithography (PPL) to generate nanoscale patterns of coenzyme A, followed by a phosphopantetheinyl transferase-mediated coupling between coenzyme A and proteins fused to the ybbR-tag. By exploiting the ability to generate protein features over large areas afforded by DPN and PPL, it was now possible to measure protein activity directly on these surfaces. It was found that proteins immobilized on the nanoscale features not only display higher activity per area with decreasing feature size, but are also robust and can be used for repeated catalytic cycles. The immobilization method is applicable to a variety of proteins and gives rise to superior activity compared to proteins attached in random orientations on the surface.

Effect of Confinement on the Mesoscale and Macroscopic Swelling of Thin Block Copolymer Films (2009)

We report on the swelling behavior and the corresponding morphological behavior of cylinder-forming polystyrene-b-polybutadiene diblock copolymers, which are confined to several layers of structures. The equilibration of thin films has been done under controlled atmosphere of a nonselective solvent. In situ spectroscopic ellipsometry measurements revealed more than 10% increase of the solvent uptake with decreasing film thickness. With scanning force microscopy of the microphase separated patterns in quenched films, the correlation between the degree of the long-range order of cylinder domains and the degree of the macroscopic swelling has been established. In the case of spontaneously formed micrometer-sized topographic features with discreet film thickness (terraces), the increased solvent uptake by thinner films holds true even for isolated terraces on the mesoscale. The observation of nonhomogeneous swelling of the films on the micrometer scale brings novel insights into the properties of confined soft matter, and suggests new approaches toward the fabrication of polymer-based nanostructured responsive materials.
Electrooptic linear chirped grating lenses on planar optical Ti:LiNbO3waveguides (1985)

These lenses perform simultaneously the basic functions of focusing, switching, and modulation of guided wave beams.
Gas phase clustering of N2 molecules on to TiO+: Comparison with Ti+ and evidence for the octahedral structure of TiO+(N2)5 (1994)

A striking difference in the clustering efficiency of Ti+ and TiO+ toward N2 or O2 has been observed in a laser vaporization high pressure mass spectrometric source. Evidence for the magic number n=5 within the sequence TiO+(N2)n is presented. The results are consistent with an octahedral structure for TiO+(N2)5.
Overlapping Community Detection via Constrained PARAFAC: A Divide and Conquer Approach (2017)

The task of community detection over complex networks is of paramount importance in a multitude of applications. The present work puts forward a top-to-bottom community identification approach, termed DC-EgoTen, in which an egonet-tensor (EgoTen) based algorithm is developed in a divide-and-conquer (DC) fashion for breaking the network into smaller subgraphs, out of which the underlying communities progressively emerge. In particular, each step of DC-EgoTen forms a multi-dimensional egonet-based representation of the graph, whose induced structure enables casting the task of overlapping community identification as a constrained PARAFAC decomposition. Thanks to the higher representational capacity of tensors, the novel egonet-based representation improves the quality of detected communities by capturing multi-hop connectivity patterns of the network. In addition, the top-to-bottom approach ensures successive refinement of identified communities, so that the desired resolution is achieved. Synthetic as well as real-world tests corroborate the effectiveness of DC-EgoTen.
Biosynthesis of the Antibiotic Echinosporin by a Novel Branch of the Shikimate Pathway (2002)

Echinosporin (1), a known antibiotic with a unique tricyclic acetal-lactone structure, is produced by Streptomyces erythraeus (strain Tü 4015), together with the novel 7-deoxyechinosporin (2) as minor compound, which was fully characterized. The biosynthesis of 1 was established by feeding experiments with 13C-labelled precursors. The results revealed that 1 was formed by the shikimate pathway, with chorismate as a biosynthetic intermediate. The proposed mechanism for the conversion of chorismate into 1 represents a new branch of the shikimate pathway, producing a nonaromatic metabolite. In addition, the influence of aromatic amino acids and of glyphosate, an inhibitor in the shikimate pathway of plants, was investigated. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)

Effects of dielectric planar interface on tight focusing coherent beam: direct comparison between observations and vectorial calculation of lateral focal patterns (2013)

We report direct observation of lateral focal patterns through an acrylic material to investigate the effects of aberrations caused by a planar dielectric interface. Numerical analyses based on vectorial Huygens-Fresnel diffraction theory were also performed to examine the behavior of three-dimensional point spread functions. Experimental and numerical results showed agreement of the behavior of the peak position in the focal patterns with changes in the interface position. Our approach has the potential to predict the effects of aberrations in confocal laser scanning microscopes and super-resolution applications.
Reduction of Endotoxin Contamination of Various Crude Vaccine Materials by Gram-Negative Bacteria Using Aminated Poly(.GAMMA.-methyl L-glutamate) Spherical Particles. (1993)

We describe a method for the removal of endotoxins from various crude antigen solutions originating from gram-negative bacteria using aminated poly(gamma-methyl L-glutamate) (PMLG) spherical particles. The aminated PMLG adsorbents showed high affinity for various purified endotoxins at an ionic strength of mu = 0.1. The endotoxin-adsorbing capacity of the adsorbent increased with increase in the amino-group content of the adsorbent. The adsorbent (3.2 meq/g amino-group content) showed the highest affinity for endotoxin at ionic strengths ranging from mu = 0.025-0.8. The adsorption of Bordetella pertussis antigen to the adsorbent decreased with increasing amino-group content of the adsorbent at an ionic strength of mu = 0.2. The adsorption of B. bronchiseptica protein to the adsorbent increased with increasing amino-group content of the adsorbent, but decreased with increasing ionic strength. The adsorbent (3.2 meq/g of amino-group content) selectively reduced endotoxin in crude antigen solutions originating from gram-negative bacteria, B. pertussis, B. bronchiseptica and Pasteurella multocida, even at a high ionic strength (mu = 0.2-0.4) without affecting the recovery of the protective antigens.
Determinants of target prioritization and regulatory hierarchy for the bacterial small RNA SgrS (2017)

ABSTRACT The mechanisms by which small RNA (sRNA) regulators select and prioritize target mRNAs remain poorly understood, but serve to promote efficient responses to environmental cues and stresses. We sought to uncover mechanisms that establish regulatory hierarchy for a model sRNA, SgrS, found in enteric bacteria and produced under conditions of metabolic stress when sugar transport and metabolism are unbalanced. SgrS post-transcriptionally controls a nine-gene regulon to restore growth and homeostasis under stress conditions. An in vivo reporter system was used to quantify SgrS-dependent regulation of target genes and established that SgrS exhibits a clear preference for certain targets, and regulates those targets efficiently even at low SgrS levels. Higher SgrS concentrations are required to regulate other targets. The position of targets in the regulatory hierarchy is not well-correlated with the predicted thermodynamic stability of SgrS-mRNA interactions or the SgrS-mRNA binding affinity as measured in vitro . Detailed analyses of SgrS interaction with asd mRNA demonstrate that SgrS binds cooperatively to two sites and remodels asd mRNA secondary structure. SgrS binding at both sites increases the efficiency of asd mRNA regulation compared to mutants that have only a single SgrS binding site. Our results suggest that sRNA selection of target mRNAs and regulatory hierarchy are influenced by several molecular features. The sRNA-mRNA interaction, including the number and position of sRNA binding sites on the mRNA and cofactors like the RNA chaperone Hfq, seem to tune the efficiency of regulation of specific mRNA targets. IMPORTANCE To survive, bacteria must respond rapidly to stress and simultaneously maintain metabolic homeostasis. The small RNA (sRNA) SgrS mediates the response to stress arising from imbalanced sugar transport and metabolism. To coordinate the stress response, SgrS regulates genes involved in sugar uptake and metabolism. Intrinsic properties of sRNAs such as SgrS allow them to regulate extensive networks of genes. To date, sRNA regulation of targets has largely been studied in the context of “one sRNA-one target”, and little is known about coordination of multi-gene regulons and sRNA regulatory network structure. Here, we explore the molecular basis for regulatory hierarchy in sRNA regulons. Our results reveal a complex interplay of factors that influence the outcome of sRNA regulation. The number and location of sRNA binding sites on mRNA targets and the participation of an RNA chaperone dictate prioritized regulation of targets to promote an efficient response to stress.
<title>Deep finlike AlGaAs nanostructure fabricated by CAIBE</title> (1998)

We show that very narrow fin-like periodic nanostructure with 0.1 micrometer width, 1 micrometer depth, and a few microns length can be fabricated on AlGaAs using Chemically-Assisted- Ion-Beam-Etching with oxidized AlGaAs as negative mask. This technique may have applications to nanoscale devices fabrication.
Laser Welding for Brazed Aluminum Alloy Component. (1997)

The formation of porosity in CO2 laser welding of brazed Al alloy plate was investigated. In order to evaluate the influence of brazing layer on the porosity formation, two types of specimens were welded. One was the brazed plate in which two plates were bonded, and the other was the Al plate without brazing layer. The obtained results are as follows.(1) The number of porosity was less in the weld fusion zone of Al alloy plate than that of the brazed plate. It was made clear that melting the brazing layer caused the porosity formation.(2) The joint shape, in which the brazing layer in weld groove was removed, was significant for reducing the porosity.(3) High speed welding was effective for reducing the porosity in the brazed plate. It was suggested that high speed welding narrowed the melted zone of brazing layer, leading to the reduction in porosity.
The Normal Range of Baseline Tryptase Should Be 1 to 15 ng/mL and Covers Healthy Individuals With HαT (2023)

Physiological levels of basal serum tryptase vary among healthy individuals, depending on the numbers of mast cells, basal secretion rate, copy numbers of the TPSAB1 gene encoding alpha tryptase, and renal function. Recently, there has been a growing debate about the normal range of tryptase because individuals with the hereditary alpha tryptasemia (HαT) trait may or may not be symptomatic, and if symptomatic, uncertainty exists as to whether this trait directly causes clinical phenotypes or aggravates certain conditions. In fact, most HαT-positive cases are regarded as asymptomatic concerning mast cell activation. To address this point, experts of the European Competence Network on Mastocytosis (ECNM) and the American Initiative in Mast Cell Diseases met at the 2022 Annual ECNM meeting and discussed the physiological tryptase range. Based on this discussion, our faculty concluded that the normal serum tryptase range should be defined in asymptomatic controls, inclusive of individuals with HαT, and based on 2 SDs covering the 95% confidence interval. By applying this definition in a literature screen, the normal basal tryptase in asymptomatic controls (HαT-positive persons included) ranges between 1 and 15 ng/mL. This definition should avoid overinterpretation, unnecessary referrals, and unnecessary anxiety or anticipatory fear of illness in healthy individuals.

Membrane topology of Escherichia coli prolipoprotein signal peptidase (signal peptidase II). (1991)

The lsp gene of Escherichia coli encodes the inner membrane enzyme, signal peptidase II (SPase II). SPase II is comprised of 164 amino acid residues and contains four hydrophobic domains. A series of lsp-phoA and lsp-lacZ gene fusions have been constructed in vitro to determine the topology of SPase II. The fusion junction for each of these gene fusions was determined by DNA sequencing. The lengths of the SPase II fragment in the fusions varied from 12 to 159 amino acid residues. Strains containing SPase II-PhoA fusions to the two predicted periplasmic loops exhibited higher levels of alkaline phosphatase activity than fusions to the predicted cytoplasmic domains. In contrast, SPase II-LacZ fusions at the cytoplasmic and the periplasmic domains of SPase II showed high and low levels of beta-galactosidase activity, respectively, a result opposite to those shown by SPase II-PhoA fusions located at precisely the same amino acid of SPase II. Taken together, these results strongly support the predicted model for SPase II topology, i.e. this enzyme spans the cytoplasmic membrane four times with both the amino and the carboxyl termini facing the cytoplasm.
Expression, purification and immunochemical characterization of recombinant bovine beta-lactoglobulin, a major cow milk allergen (1996)

The immunological characteristics of a recombinant beta-lactoglobulin were studied using monoclonal antibodies, polyclonal antiserum and sera from allergic patients. Recombinant beta-lactoglobulin (rBLG) was expressed in Escherichia coli strain DH5alpha and purified as described previously [Cho et al. (1994) J. Biol. Chem. 269, 11 102-11 107]. The method has been modified by adding an immunoaffinity purification step. A quantity of 5-10mg of purified rBLG per liter of medium culture can be produced. rBLG shared the same molecular weight as the natural BLG (nBLG) and also possessed at least one intrachain disulfide bridge. In HPLC, rBLG appeared as a single peak, and the purity was estimated to be greater than 95%. All the monoclonal antibodies (mAbs) used in this study recognized different epitopes of the BLG and presented compatible binding. No differences could be detected between rBLG and nBLG when tested in a Western blot with rabbit polyclonal antiserum or with three mAbs that bound preferentially the reduced and S-carboxymethylated form of BLG. In a competitive enzyme immunoassay (EIA) using either a rabbit polyclonal antiserum or four mAbs that recognized conformational epitopes, we could not distinguish between rBLG or nBLG. In direct ELISA using nBLG or rBLG as the immobilized allergen, we measured a similar concentration of specific anti-BLG IgE in five sera from allergic patients. The results of this study indicate that we have obtained a rBLG with biochemical and immunological properties very similar to nBLG.
Efficacy of Aerial Ultra-Low Volume Applications of Two Novel Water-Based Formulations of Unsynergized Pyrethroids Against Riceland Mosquitoes In Greece (2011)

We assessed the efficacy of ultra-low volume aerial adulticiding with 2 new water-based, unsynergized formulations of Aqua-K-Othrin (2% deltamethrin) and Pesguard S102 (10% d-phenothrin) against the riceland mosquitoes of Greece. A helicopter with Global Positioning System (GPS) navigation, real-time weather recording, and spray dispersal modeling (AgDISP) was utilized to accurately treat the experimental blocks by adjusting spray line positions to changing meteorological conditions. Two application rates were applied per formulation that corresponded to 0.75 and 1.00 g AI/ha of deltamethrin and 7.50 and 10.00 g AI/ha of d-phenothrin. The mosquitoes used for the trials were the main nuisance species found in rice field areas of Thessaloniki, which were primarily Aedes caspius, followed by Culex modestus and Anopheles sacharovi. Overall mean mortality of caged mosquitoes was 69.2% and 64.8% for deltamethrin and d-phenothrin, respectively. Mean population decrease in wild mosquito populations within the treatment areas was 76.5% and 78% for deltamethrin and d-phenothrin, respectively. The AgDISP dispersal model, coupled with GPS navigation and real-time weather recording, enabled accurate placement of the spray cloud such that the majority of the treatment area received sufficiently high droplet densities to result in uniform caged-mosquito mortality across all sampling sites.
Capillary electrophoresis and CNTs solid-phase extraction of p-nitro-phenol in water with modeling study (2020)

p-Nitro-phenol was determined in water by capillary electrophoresis and solid-phase extraction methods. The optimization was at 150 g/L concentration, 1.0 g/L dose, 7.0 pH and 15 min’ contact time. Background electrolyte was phosphate buffer (15 mM, pH 7.0) with 18 kV voltage, 215 nm detection, 20 s sample loading time. The amount of p-nitro-phenol extracted in water was 90%. The detection and quantification limits of p-nitro-phenol were 0.3 and 2.8 ng/L. The modeling results of p-nitro-phenol with CNTs indicated hydrophobic and π-π stacked interactions as the sportive forces with −1.0 kcal/mole binding energy and 1.50 M−1 binding affinity.
