678: Recovery of Urinary Continence Following Radical Prostatectomy: The Impact of Prostate Volume (2006)

The body mass index (BMI) of the WHO is an established tool to define the grade of obesity in patients. In the daily practice it seems that obese patients are more difficult to be operated on which should influence the peri-and postoperative RESULTS:. For that reason we analysed the influence of the BMI of patients undergoing radical prostatectomy (RP) for prostate cancer on the peri-and postoperative period with a special interest on continence and potency.
Low-temperature sensitivity periodically tapered photonic crystal-fiber-based refractometer (2013)

In this Letter, an all-fiber refractometer with a simple configuration of periodical tapers on a photonic crystal fiber (PCF) is proposed and investigated experimentally. The proposed fiber refractive index (RI) sensor consists of a PCF sandwiched between two standard single-mode fibers, with tapers periodically fabricated along the PCF using a CO(2) laser beam focused by a ZnSe cylindrical lens. The proposed fiber sensor can be used for RI sensing by measuring the wavelength shift of the multimode interference dip over the transmission spectrum. An average sensitivity of 222 nm/RIU has been experimentally achieved over a RI range from 1.33 to 1.38. The proposed refractometer is also significantly less sensitive to temperature, and an experimental demonstration of this reduced sensitivity is presented. The proposed RI sensor benefits from simplicity and low-cost and achieves a competitive sensitivity compared with other existing fiber-optic sensors.
Nanophononic Metamaterial: Thermal Conductivity Reduction by Local Resonance (2014)

We present the concept of a locally resonant nanophononic metamaterial for thermoelectric energy conversion. Our configuration, which is based on a silicon thin film with a periodic array of pillars erected on one or two of the free surfaces, qualitatively alters the base thin-film phonon spectrum due to a hybridization mechanism between the pillar local resonances and the underlying atomic lattice dispersion. Using an experimentally fitted lattice-dynamics-based model, we conservatively predict the metamaterial thermal conductivity to be as low as 50% of the corresponding uniform thin-film value despite the fact that the pillars add more phonon modes to the spectrum.
$l_1$-based sparsification of energy interactions in two-dimensional\n turbulent flows (2020)

In this paper, sparsity-promoting regression techniques are employed to\nautomatically identify from data relevant triadic interactions between modal\nstructures in large Galerkin-based models of two-dimensional unsteady flows.\nThe approach produces interpretable, sparsely-connected models that reproduce\nthe original dynamical behaviour at a much lower computational cost, as fewer\ntriadic interactions need to be evaluated. The key feature of the approach is\nthat dominant interactions are selected systematically from the solution of a\nconvex optimisation problem, with a unique solution, and no a priori\nassumptions on the structure of scale interactions are required. We demonstrate\nthis approach on models of two-dimensional lid-driven cavity flow at Reynolds\nnumber $Re = 2 \\times 10^4$, where fluid motion is chaotic. To understand the\nrole of the subspace utilised for the Galerkin projection on sparsity\ncharacteristics, we consider two families of models obtained from two different\nmodal decomposition techniques. The first uses energy-optimal Proper Orthogonal\nDecomposition modes, while the second uses modes oscillating at a single\nfrequency obtained from Discrete Fourier Transform of the flow snapshots. We\nshow that, in both cases, and despite no \\textit{a-priori} physical knowledge\nis incorporated into the approach, relevant interactions across the hierarchy\nof modes are identified in agreement with the expected picture of scale\ninteractions in two-dimensional turbulence. Yet, substantial structural changes\nin the interaction pattern and a quantitatively different sparsity are\nobserved. Finally, although not directly enforced in the procedure, the\nsparsified models have excellent long-term stability properties and correctly\nreproduce the spatio-temporal evolution of dominant flow structures in the\ncavity.\n
Vertical-Coupling Mirror Array for InP-PIC Wafer-Level Optical I/O with > 100-nm Wavelength Bandwidth (2022)

We developed a vertical-coupling mirror for InP photonic integrated circuits. An asymmetric Mach-Zehnder interferometer with the mirror exhibits little wavelength-dependent loss and high extinction ratio of >20 dB over the 100-nm wavelength bandwidth.
Lateral transfer of tetrahymanol-synthesizing genes has allowed multiple diverse eukaryote lineages to independently adapt to environments without oxygen (2012)

Sterols are key components of eukaryotic cellular membranes that are synthesized by multi-enzyme pathways that require molecular oxygen. Because prokaryotes fundamentally lack sterols, it is unclear how the vast diversity of bacterivorous eukaryotes that inhabit hypoxic environments obtain, or synthesize, sterols. Here we show that tetrahymanol, a triterpenoid that does not require molecular oxygen for its biosynthesis, likely functions as a surrogate of sterol in eukaryotes inhabiting oxygen-poor environments. Genes encoding the tetrahymanol synthesizing enzyme squalene-tetrahymanol cyclase were found from several phylogenetically diverged eukaryotes that live in oxygen-poor environments and appear to have been laterally transferred among such eukaryotes.
Method of characterizing electrical contact properties of carbon nanotube coated surfaces (2006)

We present a method for electromechanical characterization of carbon nanotube (CNT) films grown on silicon substrates as potential electrical contacts. The method includes measuring the sheet resistance of a tangled CNT film, measuring the contact resistance between two tangled CNT films, and investigating the dependence on applied force and postgrowth annealing. We also characterize Au-CNT film contact resistance by simultaneous measurement of applied force and resistance. We measure a contact resistance as low as 0.024Ω∕mm2 between two films of tangled single-wall carbon nanotubes grown on a polished silicon substrate and observe an electromechanical behavior very similar to that predicted by classical contact theory.
S-layer-streptavidin fusion proteins as template for nanopatterned molecular arrays (2002)

Biomolecular self-assembly can be used as a powerful tool for nanoscale engineering. In this paper, we describe the development of building blocks for nanobiotechnology, which are based on the fusion of streptavidin to a crystalline bacterial cell surface layer (S-layer) protein with the inherent ability to self-assemble into a monomolecular protein lattice. The fusion proteins and streptavidin were produced independently in Escherichia coli, isolated, and mixed to refold and purify heterotetramers of 1:3 stoichiometry. Self-assembled chimeric S-layers could be formed in suspension, on liposomes, on silicon wafers, and on accessory cell wall polymer containing cell wall fragments. The two-dimensional protein crystals displayed streptavidin in defined repetitive spacing, and they were capable of binding d-biotin and biotinylated proteins. Therefore, the chimeric S-layer can be used as a self-assembling nanopatterned molecular affinity matrix to arrange biotinylated compounds on a surface. In addition, it has application potential as a functional coat of liposomes.
8.3 M-Pixel 480-fps Global-Shutter CMOS Image Sensor with Gain-Adaptive Column ADCs and Chip-on-Chip Stacked Integration (2017)

This paper presents a 4K2K 480-fps global-shutter CMOS image sensor with a super 35-mm format for a highly realistic digital video system. The sensor employs newly developed gain-adaptive column analog-to-digital converters to obtain input-referred dark random noise of 140 μ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Vrms</sub> for an inputreferred full-scale readout of 923 mV. An on-chip online correction of the error between two switchable gains maintained the nonlinearity of the output image within 0.18%. A chip-onchip integration process realized a front-illuminated image sensor stacked with two diced logic chips through 38-K microbump interconnections. The global-shutter pixel achieved a parasitic light sensitivity of -99.6 dB. The 16-channel output interfaces with 4.752 Gbps/ch were implemented in the stacked logic chips.
Measurement of calcitonin by immunoassay analyzers (2007)

Apparently due to non-specific effects, the DS and SC assays produced calcitonin results in samples from completely thyroidectomized patients, while the DPC assay correctly failed to detect calcitonin. Thus, the DPC assay on an Immulite 2000 analyzer may be used as a more accurate substitute for NID if the different calibration is noted.
A heritable profile of six miRNAs in autistic patients and mouse models (2020)

Autism spectrum disorder (ASD) is a group of developmental pathologies that impair social communication and cause repetitive behaviors. The suggested roles of noncoding RNAs in pathology led us to perform a comparative analysis of the microRNAs expressed in the serum of human ASD patients. The analysis of a cohort of 45 children with ASD revealed that six microRNAs (miR-19a-3p, miR-361-5p, miR-3613-3p, miR-150-5p, miR-126-3p, and miR-499a-5p) were expressed at low to very low levels compared to those in healthy controls. A similar but less pronounced decrease was registered in the clinically unaffected parents of the sick children and in their siblings but never in any genetically unrelated control. Results consistent with these observations were obtained in the blood, hypothalamus and sperm of two of the established mouse models of ASD: valproic acid-treated animals and Cc2d1a<sup>+/-</sup> heterozygotes. In both instances, the same characteristic miRNA profile was evidenced in the affected individuals and inherited together with disease symptoms in the progeny of crosses with healthy animals. The consistent association of these genetic regulatory changes with the disease provides a starting point for evaluating the changes in the activity of the target genes and, thus, the underlying mechanism(s). From the applied societal and medical perspectives, once properly confirmed in large cohorts, these observations provide tools for the very early identification of affected children and progenitors.
Studies on strain sensitivity of Trichomonas vaginalis to metronidazole. (1978)

Ninety-four strains of Trichomonas vaginalis isolated from unselected patients in Vienna during the period from November 1975 to November 1975 were subjected to sensitivity tests against metronidazole in vitro and in vivo. Nearly 90% of the isolates examined showed in vitro growth inhibition at concentrations of 0.4 to 1.6 microgram metronidazole/ml and only about 10% at concentrations of less than 0.4 microgram/ml. All isolates showed some inhibition of growth after incubation for 48 hours with 3.2 microgram metroidazole/ml. Tests on treatment carried out on experimentally infected mice revealed that all strains of T. vaginalis examined were sensitive to metronidazole (MDE: less than 3 x 35 mg/kg peroral).
Air drying of chunkwood and chips. Forest Service research note (1983)

A new method of comminuting wood has resulted in a new wood particle form called chunkwood, which is much larger than the common pulp-size chip. Chunkwood appears well suited for use as a fuel but nothing is yet known about its storage, drying, or combustion characteristics. This paper reports on two exploratory drying, or combustion characteristics. This paper reports on two exploratory drying experiments we conducted to see whether chunks, with their much larger interparticle voids, dry more readily than chips. In one experiment we used natural convective ambient air to dry chunks and chips and found that chunks dried much faster than chips.

In the frame of the Global Monitoring for Environment and Security programme (GMES), ESA is undertaking the development of the Sentinel-1, an European polar orbit satellite system for the continuation of SAR operational applications in C-Band.

This document provides the Sentinel-1 SAR calibration algorithms reflected by the so called Calibration Segment (CS) as part of the Sentinel-1 Payload Data Ground Segment (PDGS). This CS is composed of
different sub-segments in order to implement the overall SAR system calibration strategy.

The Sentinel-1 SAR calibration algorithms document identifies all requirements, procedures, algorithms as well as internal and external interfaces necessary to meet the SAR system requirements. This document does not include the overall calibration strategy.
<title>Self-organizing neural network for motion detection by a moving observer</title> (1994)

The ability to rapidly detect moving objects while dynamically exploring a work environment is an essential characteristic of any active vision system. However, many of the proposed computer vision paradigms are unable to efficiently deal with the complexities of real world situations because they employ algorithms that attempt to accurately reconstruct structure- from-motion. An alternative view is to employ algorithms that only compute the minimal amount of information necessary to solve the task at hand. One method of qualitatively detecting independently moving objects by a moving camera (or observer) is based on the notion that the projected velocity of any point on a spherical image is constrained to lie on a one-dimensional locus in a local 2-D velocity space. The velocities along this locus, called a constraint ray, correspond to the rotational and translational motion of the observer. If the observer motion is known a priori, then any object moving independently through the rigid 3- D environment will exhibit a projected velocity that does not fall on this locus. As a result, the independently moving object can be detected using a clustering algorithm. In this paper, a hybrid neural network architecture is proposed for discriminating between flow velocities that are caused by camera movement and by object motion. The computing architecture is essentially a two stage process. In the first stage, a self-organizing neural network is used to learn the constraint parameters associated with typical observer movements by moving the camera apparatus through a stationary environment. Once the observer movements have been adequately learned by the self-organizing neural network, the corresponding synaptic weight values are used to program a modified radial basis function (RBF) network. During the second stage, the RBF network architecture acts as a constraint region classifier by employing clustering strategies to label incomplete motion field information (i.e. the velocity component that is parallel to the spatial gradient).
Pulmonary Function Tests in Idiopathic Inflammatory Myopathy: Association With Clinical Parameters in Children (2013)

Assessment of PFTs in children with IIMs should be considered, since more than one-third of patients were found to be impaired. The presence of MSAs/MAAs, an elevated serum neopterin level (mean ± SD 12.4 ± 9.6 nmoles/liter, normal value <10.5), older age at diagnosis, and shorter duration of untreated disease at diagnosis suggest the presence of potential lung pathology.
Silver-catalysed protodecarboxylation of carboxylic acids (2009)

A silver-based catalyst system has been discovered that effectively promotes the protodecarboxylation of various carboxylic acids at temperatures of 80-120 degrees C--more than 50 degrees C below those of the best known copper catalysts.
Multiplicity of carotene patterns derives from competition between phytoene desaturase diversification and biological environments (2020)

Phytoene desaturases catalyse from two to six desaturation reactions on phytoene, generating a large diversity of molecules that can then be cyclised and produce, depending on the organism, many different carotenoids. We constructed a phylogenetic tree of a subset of phytoene desaturases from the CrtI family for which functional data was available. We expressed in a bacterial system eight codon optimized CrtI enzymes from different clades. Analysis of the phytoene desaturation reactions on crude extracts showed that three CrtI enzymes can catalyse up to six desaturations, forming tetradehydrolycopene. Kinetic data generated using a subset of five purified enzymes demonstrate the existence of characteristic patterns of desaturated molecules associated with various CrtI clades. The kinetic data was also analysed using a classical Michaelis-Menten kinetic model, showing that variations in the reaction rates and binding constants could explain the various carotene patterns observed. Competition between lycopene cyclase and the phytoene desaturases modified the distribution between carotene intermediates when expressed in yeast in the context of the full β-carotene production pathway. Our results demonstrate that the desaturation patterns of carotene molecules in various biological environments cannot be fully inferred from phytoene desaturases classification but is governed both by evolutionary-linked variations in the desaturation rates and competition between desaturation and cyclisation steps.

Testability design based on relevance of circuit nodes and fault diagnosis (2017)

As an important part of electronic products and systems, the fault prediction and health management of board-level circuits has attracted wide attention and the testability design is the basis of the related studies. In this paper, a new method of testability design based on the correlation of circuit nodes is proposed and used to realize the selection of test points in a high-voltage power supply. First of all, all nodes in the circuit are grouped based on correlation analysis, and then calculate the distance between the fault class according to the existing fault data to select the test points of the circuit. Finally, extract the fault features of the selected test points and diagnose the fault. The results verifies the effectiveness of the proposed method in this paper.
Blur adaptation modulates amplitude and phase spectra of perceived image (2005)

The present study conducted three psychophysical experiments to examine whether the visual system can compensate the retinal image blur induced by refractive error. In experiment 1, we measured the percentage of correct answers for Snellen letter (letter size = 0.15 deg) blurred by a myopia-simulated (2D-Gaussian) filter after 10 minutes of adaptation to blurred or non-filtered natural images. The result shows a significant improvement of percent correct by the blur adaptation. In experiment 2, an astigmatism-simulated (1D-Gaussian) filter was applied instead of the myopia-simulated filter in experiment 1. The percent correct systematically improved when the filtering orientation was identical in both letters and natural images. In experiment 3, in order to simulate the coma-like aberration, non-linear phase characteristics were added to the astigmatism-simulated filter in experiment 2. The percent correct, in a similar fashion with the other experiments, improved by the adaptation to natural images blurred by the identical filter used for the letters. However, only for the coma-like aberration, large adaptation area (at least up to 2 deg) was necessary for the improvement of percent correct. These results suggest the existence of neural compensational mechanisms that modulate not only amplitude but also phase spectra of perceived image.
RT‐PCR Detection of Odontoglossum ringspot virus, Cymbidium mosaic virus and Tospoviruses and Association of Infections with Leaf‐Yellowing Symptoms in Phalaenopsis (2008)

Abstract Leaf‐yellowing symptoms in Phalaenopsis are most important effects in its commercial production in Japan and their cause has not yet been clarified. In the present study, Odontoglossum ringspot virus (ORSV), Cymbidium mosaic virus (CymMV) and tospoviruses were evaluated by reverse transcription‐polymerase chain reaction (RT‐PCR) in Phalaenopsis showing leaf‐yellowing symptoms. Ring, spot, mosaic, necrosis and other symptom types were observed in 42%, 24%, 25%, 16% and 44% of the tested plants respectively. ORSV was detected in 55% of the plants, particularly in 35 of 42 plants with ring symptoms. CymMV was detected in 34% of the plants, particularly in 18 of 25 plants with mosaic symptoms. Plants co‐infected with both viruses tended to show severe symptoms. In spite of systemic infection by inoculation of ORSV , no clear ring symptoms were observed in any plant for 6 months. Symptoms of leaf‐yellowing were significantly reduced after 3 months. These results suggest that the symptoms can be associated with the viruses but occurred and alleviated over time and by changes in the environmental conditions. No tospoviruses were detected in 70 tested plants. ORSV and CymMV were simultaneously detected by RT‐PCR using reported primers for ORSV and newly designed primers for CymMV using an efficient direct tube RNA extraction technique providing more cost‐effective RT‐PCR screening. No viruses were detected by RT‐PCR in several plants showing spot or ring symptoms, suggesting the presence of other causal agents related to these symptoms.
