<title>Lippmann photographic process put to practice with available materials</title> (1996)

The Lippmann photographic process relied on very fine grain silver halide emulsions with panchromatic spectral sensitizers. Emulsions for this process have not been commercially available since around the turn of the century. Recent availability of suitable Russian silver halide emulsions (PFG-03c) from Slavich Company made revisiting this process possible. Experimentation with these plates resulted in full color spectrums and outdoor still life photographs that gave a basis for further investigation of making laboratory silver halide emulsions. This paper will present procedures and results for the making of Lippmann photographs from silver halide emulsions and from other recording materials.
Automatic call generation and analysis - network testing and cellular survey tools (1996)

There is a growing need for cellular network performance surveys in an increasingly competitive cellular phone environment. New operators are under great pressure from their share holders to bring their network up for commercial service but at the same time they do not want to compromise their service quality. For existing operators, the drive is to achieve optimum spectral efficiency for the growing traffic demand in their preciously allocated spectral band. The motivation is threefold, (1) to quantify network performance and operating parameters, (2) to investigate specific network problems, and (3) to optimise the network. The Surveyor is designed to enable engineers to perform field surveys in these areas with ease. It is a proven system helping operators over the world to capture and analyse cellular data which enables engineers to constantly monitor, improve, and refine a cellular mobile network's quality of service. The Surveyor is an advanced continuous (or carrier) wave (CW) and handset survey system which features full handset message decoding in real-time for up to eight or more handsets of the same or different types. It can interface to practically any Global Positioning System (GPS) navigation system and also supports other navigation systems. (6 pages)
Cognitive multistatic AUV networks (2014)

Autonomous underwater vehicle (AUV) platforms are low-cost devices with respect to conventional detection and tracking systems for the purpose of anti-submarine warfare (ASW). Unfortunately, the increased level of manageability is often paid in terms of capabilities, e.g., limited speed and endurance, inferior sensor payloads, and so on. This work exploits two fundamental concepts aimed at filling the consequent performance gap. First, a multistatic network of AUVs is considered, where a smart and collaborative multi-sensor data fusion allows going beyond the individual sensors limitations. Then, we focus on the cognitive paradigm, where the single AUV units optimize their future actions (i.e., their path planning) in view of the final inference purpose of the network, and based on the evidence collected up to the present. A multistatic configuration of the platforms and the corresponding acoustic model are considered, and taken into account in order to derive a proper Bayesian model. Using the information contained in the Bayesian full posterior, cognitive detection and tracking algorithms are designed. Seeing them at work in practical scenarios shows the benefits of the cognitive network paradigm.
A Performance Evaluation of 3D Keypoint Detectors (2011)

Intense research activity on 3D data analysis tasks, such as object recognition and shape retrieval, has recently fostered the proposal of many techniques to perform detection of repeatable and distinctive key points in 3D surfaces. This high number of proposals has not been accompanied yet by a comprehensive comparative evaluation of the methods. Motivated by this, our work proposes a performance evaluation of the state-of-the-art in 3D key point detection, mainly addressing the task of 3D object recognition. The evaluation is carried out by analyzing the performance of several prominent methods in terms of robustness to noise (real and synthetic), presence of clutter, occlusions and point-of-view variations.
Pseudorandom recursions II (2012)

We present our earlier results (not included in Hars and Petruska due to space and time limitations), as well as some updated versions of those, and a few more recent pseudorandom number generator designs. These tell a systems designer which computer word lengths are suitable for certain high-quality pseudorandom number generators, and which constructions of a large family of designs provide long cycles, the most important property of such generators. The employed mathematical tools could help assessing the bit-mixing and mapping properties of a large class of iterated functions, performing only non-multiplicative computer operations: SHIFT, ROTATE, ADD, and XOR.
Förster-Type Resonant Energy Transfer Influenced by Metal Nanoparticles (2008)

We show experimentally and numerically that Forster-type resonant energy transfer between molecules strongly depends on the interaction with plasmonic resonances in a nearby metallic nanoparticle (MNP). Acceptor luminescence emerges at the expense of donor luminescence when an acceptor molecule harvests the donor's near-field energy. By tuning the resonance of a close-by MNP across the transition energy bands of the molecules, we show how the molecular luminescence is affected and in part even strongly increased.
Self comes to mind : constructing the conscious brain (2010)

This title is winner of the CORINE International Book Award 2011. It is from one of the most important neuroscientists at work today, a path-breaking investigation of a question that has confounded neurologists, philosophers, cognitive scientists and psychologists for centuries: how is consciousness created? Antonio Damasio has spent the past thirty years studying and writing about how the brain operates, and his work has garnered acclaim for its singular melding of the scientific and the humanistic. In Self Comes to Mind, he goes against the long-standing idea that consciousness is somehow separate from the body, presenting compelling new scientific evidence that consciousness - what we think of as a mind with a self - is in fact a biological process created by a living organism. The result is a groundbreaking investigative journey into the neurobiological foundations of mind and self.

Interaction of angiogenic microvessels with the extracellular matrix (2007)

The extracellular matrix (ECM) plays a critical role in angiogenesis by providing biochemical and positional cues, as well as by mechanically influencing microvessel cell behavior. Considerable information is known concerning the biochemical cues relevant to angiogenesis, but less is known about the mechanical dynamics during active angiogenesis. The objective of this study was to characterize changes in the material properties of a simple angiogenic tissue before and during angiogenesis. During sprouting, there was an overall decrease in tissue stiffness followed by an increase during neovessel elongation. The fall in matrix stiffness coincided with peak matrix metalloproteinase mRNA expression and elevated proteolytic activity. An elevated expression of genes for ECM components and cell-ECM interaction molecules and a subsequent drop in proteolytic activity (although enzyme levels remained elevated) coincided with the subsequent stiffening. The results of this study show that the mechanical properties of a scaffold tissue may be actively modified during angiogenesis by the growing microvasculature.
An Analysis of Pricing in the U.S. Cotton Seed Market (2009)

The purpose of the research in this paper is to investigate the impact of differentiated vertical strategies by agricultural biotechnology firms in the U.S. cottonseed market. The model advances the measurement of industry concentration to consider substitution/complementarity relationships among differentiated products delivered under different vertical structures. We find evidence of sub-additive pricing in the stacking of bundled biotech traits. Prices paid by farmers for cottonseed sold under vertical integration are found to be higher than under licensing. The model is flexible and allows for evaluation of the effects of changing market structures. The parameters on traditional measures of concentration indicate that higher concentration leads to higher prices. The effects of cross-market concentrations stress the need to conduct the analysis in a multi-market context.
A multiresolution image based approach for correction of partial volume effects in emission tomography (2006)

Partial volume effects (PVEs) are consequences of the limited spatial resolution in emission tomography. They lead to a loss of signal in tissues of size similar to the point spread function and induce activity spillover between regions. Although PVE can be corrected for by using algorithms that provide the correct radioactivity concentration in a series of regions of interest (ROIs), so far little attention has been given to the possibility of creating improved images as a result of PVE correction. Potential advantages of PVE-corrected images include the ability to accurately delineate functional volumes as well as improving tumour-to-background ratio, resulting in an associated improvement in the analysis of response to therapy studies and diagnostic examinations, respectively. The objective of our study was therefore to develop a methodology for PVE correction not only to enable the accurate recuperation of activity concentrations, but also to generate PVE-corrected images. In the multiresolution analysis that we define here, details of a high-resolution image H (MRI or CT) are extracted, transformed and integrated in a low-resolution image L (PET or SPECT). A discrete wavelet transform of both H and L images is performed by using the "à trous" algorithm, which allows the spatial frequencies (details, edges, textures) to be obtained easily at a level of resolution common to H and L. A model is then inferred to build the lacking details of L from the high-frequency details in H. The process was successfully tested on synthetic and simulated data, proving the ability to obtain accurately corrected images. Quantitative PVE correction was found to be comparable with a method considered as a reference but limited to ROI analyses. Visual improvement and quantitative correction were also obtained in two examples of clinical images, the first using a combined PET/CT scanner with a lymphoma patient and the second using a FDG brain PET and corresponding T1-weighted MRI in an epileptic patient.
Dynamic Gd‐DTPA enhanced MRI as a surrogate marker of angiogenesis in tissue‐engineered bladder constructs: A feasibility study in rabbits (2005)

Findings support DCE-MRI for evaluating angiogenesis in bladder constructs and suggest vessel changes other than density. Future studies should incorporate larger contrast agents and permeability assessment to devise an optimal DCE-MRI strategy.
Preparation and Properties of Magnetically-interacting Polymer with Cupper(II) and Vanadyl(II) Poporphyrins (1987)

Abstract Polyacrylate having tetraphenylporphinatocupper(II) and tetraphenylporphinatovanadyl(II) in its side chains (Cu : V = 1 : 1.2) has been prepared by the radical copolymerization of the corresponding acrylates. The temperature dependence of its magnetic susceptibility indicates the existence of ferromagnetic interaction.
Adaptive rate and power DS/CDMA communications in fading channels (1999)

We investigate the average information rates attained by adapting the transmit power and the information rate relative to channel variations in code division multiple access communication systems. Our results show that the rate adaptation provides a higher average information rate than the power adaptation for a given average transmit power, and the rate increase when using rate adaptation is more significant for channels with a faster decaying multipath intensity profile and weaker line-of-sight component.

Visualizing parallel programs and performance (1995)

Performance visualization uses graphical display techniques to analyze performance data and improve understanding of complex performance phenomena. Current parallel performance visualizations are predominantly two-dimensional. A primary goal of our work is to develop new methods for rapidly prototyping multidimensional performance visualizations. By applying the tools of scientific visualization, we can prototype these next-generation displays for performance visualization-if not implement them as end user tools-using existing software products and graphical techniques that physicists, oceanographers, and meteorologists have used for several years.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Linoleic and α-linolenic acid as precursor and inhibitor for the synthesis of long-chain polyunsaturated fatty acids in liver and brain of growing pigs (2011)

Studies suggested that in human adults, linoleic acid (LA) inhibits the biosynthesis of n-3 long-chain polyunsaturated fatty acids (LC-PUFA), but their effects in growing subjects are largely unknown. We used growing pigs as a model to investigate whether high LA intake affects the conversion of n-3 LC-PUFA by determining fatty acid composition and mRNA levels of Δ5- and Δ6 desaturase and elongase 2 and -5 in liver and brain. In a 2 × 2 factorial arrangement, 32 gilts from eight litters were assigned to one of the four dietary treatments, varying in LA and α-linolenic acid (ALA) intakes. Low ALA and LA intakes were 0.15 and 1.31, and high ALA and LA intakes were 1.48 and 2.65 g/kg BW0.75 per day, respectively. LA intake increased arachidonic acid (ARA) in liver. ALA intake increased eicosapentaenoic acid (EPA) concentrations, but decreased docosahexaenoic acid (DHA) (all P < 0.01) in liver. Competition between the n-3 and n-6 LC-PUFA biosynthetic pathways was evidenced by reductions of ARA (>40%) at high ALA intakes. Concentration of EPA (>35%) and DHA (>20%) was decreased by high LA intake (all P < 0.001). Liver mRNA levels of Δ5- and Δ6 desaturase were increased by LA, and that of elongase 2 by both ALA and LA intakes. In contrast, brain DHA was virtually unaffected by dietary LA and ALA. Generally, dietary LA inhibited the biosynthesis of n-3 LC-PUFA in liver. ALA strongly affects the conversion of both hepatic n-3 and n-6 LC-PUFA. DHA levels in brain were irresponsive to these diets. Apart from Δ6 desaturase, elongase 2 may be a rate-limiting enzyme in the formation of DHA.
Identification of Neutral Cholesterol Ester Hydrolase, a Key Enzyme Removing Cholesterol from Macrophages (2008)

Unstable lipid-rich plaques in atherosclerosis are characterized by the accumulation of macrophage foam cells loaded with cholesterol ester (CE). Although hormone-sensitive lipase and cholesteryl ester hydrolase (CEH) have been proposed to mediate the hydrolysis of CE in macrophages, circumstantial evidence suggests the presence of other enzymes with neutral cholesterol ester hydrolase (nCEH) activity. Here we show that the murine orthologue of KIAA1363, designated as neutral cholesterol ester hydrolase (NCEH), is a microsomal nCEH with high expression in murine and human macrophages. The effect of various concentrations of NaCl on its nCEH activity resembles that on endogenous nCEH activity of macrophages. RNA silencing of NCEH decreases nCEH activity at least by 50%; conversely, its overexpression inhibits the CE formation in macrophages. Immunohistochemistry reveals that NCEH is expressed in macrophage foam cells in atherosclerotic lesions. These data indicate that NCEH is responsible for a major part of nCEH activity in macrophages and may be a potential therapeutic target for the prevention of atherosclerosis.

Gut microbiota differs between children with Inflammatory Bowel Disease and healthy siblings in taxonomic and functional composition: a metagenomic analysis (2016)

Current treatment for pediatric inflammatory bowel disease (IBD) patients is often ineffective, with serious side effects. Manipulating the gut microbiota via fecal microbiota transplantation (FMT) is an emerging treatment approach but remains controversial. We aimed to assess the composition of the fecal microbiome through a comparison of pediatric IBD patients to their healthy siblings, evaluating risks and prospects for FMT in this setting. A case-control (sibling) study was conducted analyzing fecal samples of six children with Crohn's disease (CD), six children with ulcerative colitis (UC) and 12 healthy siblings by metagenomic sequencing. In addition, lifetime antibiotic intake was retrospectively determined. Species richness and diversity were significantly reduced in UC patients compared with control [Mann-Whitney <i>U</i>-test false discovery rate (MWU FDR) = 0.011]. In UC, bacteria positively influencing gut homeostasis, e.g., <i>Eubacterium rectale</i> and <i>Faecalibacterium prausnitzii</i>, were significantly reduced in abundance (MWU FDR = 0.05). Known pathobionts like <i>Escherichia coli</i> were enriched in UC patients (MWU FDR = 0.084). Moreover, <i>E. coli</i> abundance correlated positively with that of several virulence genes (SCC > 0.65, FDR < 0.1). A shift toward antibiotic-resistant taxa in both IBD groups distinguished them from controls [MWU Benjamini-Hochberg-Yekutieli procedure (BY) FDR = 0.062 in UC, MWU BY FDR = 0.019 in CD). The collected results confirm a microbial dysbiosis in pediatric UC, and to a lesser extent in CD patients, replicating associations found previously using different methods. Taken together, these observations suggest microbiotal remodeling therapy from family donors, at least for children with UC, as a viable option.<b>NEW & NOTEWORTHY</b> In this sibling study, prior reports of microbial dysbiosis in IBD patients from 16S rRNA sequencing was verified using deep shotgun sequencing and augmented with insights into the abundance of bacterial virulence genes and bacterial antibiotic resistance determinants, seen against the background of data on the specific antibiotic intake of each of the study participants. The observed dysbiosis, which distinguishes patients from siblings, highlights such siblings as potential donors for microbiotal remodeling therapy in IBD.
Poly‐2‐oxazolidinone aus isocyanaten und epoxiden (1979)

Abstract Poly‐2‐oxazolidinone lassen sich aus Diisocyanaten und Diepoxiden herstellen. Die Umsetzung kann in polaren Lösungsmitteln wie Hexamethylphosphoräuretriamid durchgeführt werden. Aus aliphatischen Diisocyanaten entstehen dabei helle Produkte, die relativ niedrige Schmelzpunkte (zwischen 80 und 130 °C) haben und in Dimethylformamid löslich sind. Aromatische Diisocyanate liefern in Abhängigkeit vom Diepoxid höherschmelzende (210–230°C), teilweise auch dunkle, unlösliche und unschmelzbare Polymere, was vermutlich u.a. auf Nebenreaktionen der Isocyanate mit dem Lösungsmittel zurückzuführen ist. Diese Nebenreaktionen können durch Verwendung von niedrigschmelzenden Monooxazolidinonen als Lösungsmittel vermieden werden. Die thermische Stabilität der hergestellten Mono‐, Bis‐und Poly‐2‐oxazolidinone wurde thermoanalytisch bestimmt. Der thermische Abbau der Polymeren beginnt zwischen 250 und 340°C und wird durch Abspaltung von Kohlendioxid eingeleitet; eine eindeutige Korrelation zwischen Struktur und thermischer Stabilität konnte jedoch nicht festgestellt werden.
Ultra-wideband pulse-based directional modulation (2015)

This paper presents a time-domain pulse-based directional modulation technique that enables secure wireless communication at the physical level. We use a train of sub-200psec pulses to achieve an information beamwidth of 1° while using antennas with a broad radiation pattern. The proposed technique leverages the advantages of a pulse-based system to demonstrate secure communication.
The hemagglutinin gene A (hagA) of Porphyromonas gingivalis 381 contains four large, contiguous, direct repeats (1996)

Porphyromonas gingivalis is a gram-negative anaerobic bacterial species strongly associated with adult periodontitis. One of its distinguishing characteristics and putative virulence properties is the ability to agglutinate erythrocytes. We have previously reported the cloning of multiple hemagglutinin genes from P. gingivalis 381. Subsequent sequencing of clone ST 2 revealed that the cloned fragment contained only an internal portion of the gene which lacked both start and stop codons. We here report the cloning and sequencing of the entire gene, designated hagA, as well as its relationship to other genes of this species. By use of inverse PCR technology and the construction of several additional genomic libraries, the complete open reading frame of hagA was found to be 7,887 bp in length, encoding a protein of 2,628 amino acids with a molecular mass of 283.3 kDa, which is among the largest genes ever cloned from a prokaryote to date. Within its open reading frame, four large, contiguous, direct repeats (varying from 1,318 to 1,368 bp) were identified. The repeat unit (HArep), which is assumed to contain the hemagglutinin domain, is also present in other recently reported protease and hemagglutinin genes in P. gingivalis. Thus, we propose that hagA and the other genes which share the HArep sequence form a multigene family with hagA as a central member.
