PROBA V multispectral imager: status (2017)

PROBA V is an ESA mission devoted to the observation of the Earth’s vegetation, providing data continuity with the Spot 4 and 5 vegetation payloads. Thanks to the heritage of the Proba series, the satellite’s platform is smaller than a cubic metre, accommodating the main payload, i.e. the Vegetation Instrument (VI), and some technology demonstrators. The VI extremely wide viewing swath, together with a polar low Earth orbit, enables daily revisits during 2.5 years, with a possible extension to 5 years. The mission, whose satellite is developed by Belgian QuinetiQ Space, is actually in Phase D and the targeted launch is early 2013 with the VEGA launcher. The Vegetation Instrument is a high spatial resolution pushbroom 4 spectral bands imager composed of three distinct Spectral Imagers (SI). Each SI has 34&deg; Field Of View (FOV) across track, and the total FOV of the VI is 102&deg;, covering an Earth swath of 2260 Km with ground sampling distance down to 96 m at Nadir for VNIR bands. The spectral bands are centred around 460 nm for the blue, 655 nm for the red, 845nm for the NIR and 1600 nm for the SWIR. The imaging telescope is built from a Three-Mirrors Anastigmat (TMA) configuration, including two highly aspheric mirrors. The optics is manufactured from special grade aluminium by diamond turning. The material being identical to the whole structure, no defocus or stresses build up with temperature variations in flight. This paper gives an overview of the VI performances, and focuses on the results of the optical tests and on-ground calibrations.
W-band three-dimensional surveillance imaging system (2015)

Millimeter-waves are nonionizing, readily penetrate common clothing material, and are reflected from the human body and any concealed items. In this paper, a 3-D imaging system is proposed. It works in W-band in order to achieve high resolution. The image reconstruction algorithm used to form a focused image at near field is based on spatial frequency domain, and process of algorithm is displayed detail. The experiment results show that the resolution of the image is better than 5mm. This system is described in detail along with imaging results.
Bactericidal activity of ceftizoxime, cefotetan, and clindamycin against cefoxitro-resistant strains of the Bacteroides fragilis group (1991)

The bactericidal activity of ceftizoxime, cefotetan, and clindamycin at 0.5 x MIC, 1 x MIC, and 4 x MIC was determined by killing kinetic studies for 12 cefoxitin-resistant strains of the Bacteroides fragilis group. Ceftizoxime and clindamycin had greater bactericidal activity than cefotetan. The degree of bactericidal activity of each compound increased as the concentration increased from subinhibitory (0.5 x MIC) to suprainhibitory concentrations (4 x MIC). Comparison of the bactericidal activity at the MIC of the test agents with the MIC showed greater killing of susceptible strains than the resistant strains. Interestingly, ceftizoxime was more active than clindamycin, or cefotetan, against strains with high cefoxitin MIC values.
Signal-to-noise ratio definition for magnetic recording channels with transition noise (2000)

This paper proposes a new signal-to-noise ratio (SNR) definition for magnetic recording channels with both additive and medium noise components. The proposed SNR is a generalized version of E/sub b//M/sub 0/, the information bit energy to noise spectral height ratio, widely used in average-power-constrained communication channels with additive white noise. The goal is to facilitate comparison of efficiencies of read channels that may operate at different symbol densities because of varying code rates.
Field tests of adaptive modulation and coding for underwater acoustic OFDM (2013)

Adaptive modulation and coding (AMC) technique can be applied in underwater acoustic communications to improve the system data rate as well as the robustness in varying channel conditions. In this paper, we demonstrate an OFDM based AMC operation using a number of transmission modes with different data rates. We propose to use the effective signal-to-noise ratio (SNR) computed after channel estimation and channel decoding as performance indicator for mode switching, instead of input SNR and pilot SNR. Real time AMC tests have been conducted in a recent sea experiment.
Behavioural inheritance in object-oriented models for mechatronic systems (2006)

This paper describes a formal framework for Object-Oriented (O-O) modelling of mechatronic systems, whose main contribution is, on the one hand, to unify the modelling approaches for dynamical systems and for industrial control software and, on the other hand, to provide a definition of inheritance, a cardinal concept in object-orientation, which emphasises the behavioural conformity of basic and derived classes of objects. The proposed framework exploits the coalgebraic description of software artefacts to provide a connection between the behavioural approach for modelling dynamical systems and the O-O approach for software modelling and design. In particular, our definition of inheritance aims to allow control engineers to apply the design by extension methodology, widely used in software engineering, to the development of mechatronic components for manufacturing systems.
Synthesis and Characterization of Poly(methyl methacrylate) Backbone Polymers Containing Side‐Chain Pendant Ruthenium(II) Bis‐Terpyridine Complexes With an Elongated Conjugated System (2012)

Abstract A series of functionalized methacrylate monomers has been polymerized utilizing the reversible addition–fragmentation chain transfer (RAFT) polymerization procedure in order to synthesize side‐chain pendant Ru(II) bis‐terpyridine complexes in poly(methyl methacrylate) (PMMA) polymers by three different reaction routes. The polymers were characterized by size exclusion chromatography (SEC), 1 H NMR spectroscopy, and thermal analysis. The photophysical properties of the polymers were studied by UV‐vis absorption and emission spectroscopy. Temperature dependent luminescence lifetime measurements were carried out for both monomers and polymers. In addition, cyclic voltammetry (CV) measurements were performed. All polymers revealed the typical characteristics of the Ru complex in terms of optoelectronical and electrochemical features combined with the film forming properties of a common polymer.
CHORD ESTIMATION USING CHORD TEMPLATES AND HMM (2008)

This document describes a submission to the Music Information Retrieval Evaluation eXchange in the Audio Chord Recognition task. A set of chroma vectors representing the pitch content of the audio file over time is extracted. From these observations the chord progression is then estimated using hidden Markov models. The system takes into account the presence of higher harmonics of pitch notes and includes some music knowledge. In this approach, no training is needed. 1

Le présent ouvrage propose les parties les plus originales d’une remarquable Thèse de Doctorat de Géographie, soutenue en Sorbonne au mois de décembre 1996. Plus peut-être que dans bien d’autres sciences sociales, du fait sans doute de la puissance des chapelles établies, les constructions théoriques globales et originales sont rares en Géographie. Le livre, comme la Thèse, méritent alors d’être salués, pour la nouveauté du propos, le courage intellectuel qu’ils traduisent, le sérieux et la q...
High-isolation Dual-polarized Patch Antenna Array (2020)

A novel high-isolation dual-polarized patch antenna array based on 1x2 sub-array is designed. The isolations between different sub-arrays or different polarizations in the same subarray of the 2x2 array are promoted by simply loading several U-type and I-type grounded strips together with a big cross strip around the antennas on the same layer. Consequently, all isolations between different ports of the 2x2 dual-polarized antenna array can achieve a very high level of over 25 dB in a relatively broad band of 3.4GHz ~ 3.6GHz. Moreover, these strips have little influence on radiation characteristics of the antenna array, which can ensure that the antenna is working properly.
Application of Curcumin as Ligand in [Pd(Curc‐H) 2 ] Catalyst for Carbon‐Carbon Bond Formation in Heck and Suzuki Coupling Reactions (2018)

Abstract The Pd‐II catalysed C−C bond formation Heck and Suzuki coupling reactions with moderate to excellent yields are reported, using curcumin as ligand, which is extracted from turmeric powder. The application of curcumin based [Pd(Curc‐H) 2 ] catalyst in organic synthesis tested here, is the novelty of this protocol. This novel, highly efficient and simple protocol shows a broad substrate scope for aryl halides, substituted alkenes and phenyl boronic acid as coupling partners.

The equine gastrointestinal microbiome: Impacts of weight-loss (2019)

Abstract Background Obesity is an important equine welfare issue. Whilst dietary restriction is the most effective weight-loss tool, individual animals range in their weight-loss propensity. Gastrointestinal-derived bacteria play a fundamental role in host-health and have been associated with obesity and weight-loss in other species. This study evaluated the faecal microbiome (next-generation sequencing of 16S rRNA genes) of 15 obese Welsh Mountain pony mares, in the same 11-week period across 2 years (n = 8 Year 1; n = 7 Year 2). Following a 4-week acclimation period (pre-diet phase) during which time individuals were fed the same hay to maintenance (2% body mass (BM) as daily dry matter (DM) intake), animals underwent a 7-week period of dietary restriction (1% BM hay as daily DM intake). Faeces were sampled on the final 3 days of the pre-diet phase and the final 3 days of the dietary restriction phase. Bacterial communities were determined using Next Generation Sequencing of amplified V1-V2 hypervariable regions of bacterial 16S rRNA.Results Losses in body mass ranged from 7.11% to 11.59%. Changes in the faecal microbiome composition following weight-loss included a reduction in the relative abundance of Firmicutes and Tenericutes and a reduction in indices of bacterial diversity. Pre-diet diversity was negatively associated with weight-loss. Pre-diet faecal acetate concentration was a strong predictor of subsequent weight-loss and negatively associated with Sphaerochaeta (Spirochaetes phylum) abundance. When animals were divided into 3 groups (high, mid, low) based overall weight loss, pre-diet bacterial community structure was found to have the greatest divergence between the high and low weight-loss groups (R = 0.67, p &lt; 0.01), following PERMANOVA and ANOSIM analysis.Conclusions Weight-loss in this group of ponies was associated with lower pre-diet faecal bacterial diversity and greater pre-diet acetate concentration. Overall, these data support a role for the faecal microbiome in weight-loss propensity in ponies and provide a baseline for research evaluating elements of the faecal microbiome in predicting weight-loss success in larger cohorts.
Direct observation and stability of active species in cationic polymerization: A reexamination of the polymerization of styrene initiated by triflic acid (1992)

Abstract Polymerization of styrene initiated by triflic acid in CH 2 Cl 2 solution was reexamined, using a new stopped‐flow device working in high purity conditions over a wide temperature range. Monomer and styryl cation were followed simultaneously through their respective absorbances at 290 and 340 nm. Initiation is very rapid, and cations concentration reaches a plateau the duration of which is depending on temperature. In our conditions (I 0 = 0.5 − 9.10 −3 M, M 0 /I 0 = 1 to 20), cations concentration is so low at room temperature that it is almost unmeasurable. At −65°C, it is 100 times higher, remains constant for several seconds and complete termination takes place within a minute or more. Such a profile of cation evolution agrees with an equilibrium situation between initiation and a much more temperature‐dependent backward deprotonation. Apparent initial rate of initiation is first order with respect to monomer, but the order with respect to initiator was found very high and variable with temperature (from 4.5 at −65°C to 3 at −20°C). This supports the presence, even if they are in low concentration, of acid high agregates, the reactivity of which increases with size. A first order monomer consumption is observed during the plateau, which leads to k p values ranging from 10 3 at −65°C to 9.10 4 M −1 .s −1 at −10°C (Ep # = 43 kJ.mol −1 ). The disappearance of cations, which follows the plateau, slows down and becomes unimolecular when monomer consumption is complete, and k t values range from 6.10 −2 s −1 at −65°C to 1.2s −1 at −23°C (E t # = 33 kJ.mol −1 ).
Selection, Optimization, Compensation, and Equilibrium Dynamics (2013)

One of the major theoretic frameworks through which human development is studied is a process-oriented model involving selection, optimization, and compensation. These three processes each provide accounts for methods by which gains are maximized and losses minimized throughout the lifespan, in particular during later life. These processes can be cast within the framework of dynamical systems theory and then modeled using differential equations. The current article will review basic tenets of selection, optimization, and compensation while introducing language and concepts from dynamical systems. Four categories of interindividual differences and intraindividual variability in dynamics are then described and discussed in the context of selection, optimization, and compensation.
Bipolar cascade lasers with quantum well tunnel junctions (2003)

Bipolar cascade lasers with quantum wells (QWs) in tunnel junctions are proposed and demonstrated with emission wavelength near 2 μm based on an InGaAs/InP material system. These bipolar cascade lasers with QW tunnel junctions exhibited superior performance characteristics such as significantly reduced threshold voltage, increased quantum efficiency (&amp;gt;100%) and operation temperature over similar lasers without a QW in the tunnel junction. These broad-area lasers operated at temperatures up to 240 K in continuous wave mode and up to room temperature in pulsed mode.
Optimal filtering in fractional Fourier domains (1997)

For time-invariant degradation models and stationary signals and noise, the classical Fourier domain Wiener filter, which can be implemented in O(N log N) time, gives the minimum mean-square-error estimate of the original undistorted signal. For time-varying degradations and nonstationary processes, however, the optimal linear estimate requires O(N/sup 2/) time for implementation. We consider filtering in fractional Fourier domains, which enables significant reduction of the error compared with ordinary Fourier domain filtering for certain types of degradation and noise (especially of chirped nature), while requiring only O(N log N) implementation time. Thus, improved performance is achieved at no additional cost. Expressions for the optimal filter functions in fractional domains are derived, and several illustrative examples are given in which significant reduction of the error (by a factor of 50) is obtained.

Evolutionary Sequence Modeling for Discovery of Peptide Hormones (2007)

We describe a computational framework that models spatial structure along the genomic sequence simultaneously with the temporal evolutionary path structure and show how such models can be used to discover new functional molecules through cross-genomic sequence comparisons. The framework incorporates a priori high-level knowledge of structural and evolutionary constraints in terms of a hierarchical grammar of evolutionary probabilistic models. In particular, we demonstrate a novel computational method for identifying novel prohormones and the processed peptide sites by producing sequence alignments across many species at the functional-element level. We present experimental results with an initial implementation of the algorithm used to identify potential prohormones by comparing the human and mouse proteins, resulting in high accuracy identification in a known set of proteins and a putative novel hormone from an unknown set. Finally, in order to validate the computational methodology, we present the basic molecular biological characterization of the novel putative peptide hormone, including identification in the brain and regional localizations. The success of this approach will have a great impact on our understanding of GPCRs and associated pathways, and help us identify new targets for drug development.
The Effects of Decoy Gambles on Individual Choice (1999)

Abstract A number of studies demonstrate that individual choice can be influenced by alternatives which should be irrelevant according to standard choice theory. In these studies it has been observed that introducing a decoy option, which is either asymmetrically dominated by a target option or which makes the target a compromise, increases the likelihood of choosing the target. A common feature of earlier research on decoy effects is the use of hypothetical choice tasks. The aim of this paper is to investigate decoy effects in a properly controlled experiment where subjects are given real incentives. Here, monetary gambles are used as alternatives. The results demonstrate that decoy effects persist despite the use of real incentives.
The use of microsatellite instability, immunohistochemistry and other variables in determining the clinical significance of MLH1 and MSH2 unclassified variants in Lynch syndrome (2006)

Missense changes constitute approximately 1/3 and 1/5 of all rare sequence constitutional variations identified in the MLH1 and MSH2 genes by mutation screening. They represent a challenge for the clinician and for the genetic counselor, who often cannot use them for the management of Lynch syndrome families. Several parameters can be evaluated to gain insight into the significance of such unclassified variants (UVs). These include analysis of microsatellite instability (MSI), immunohistochemistry of mismatch repair (MMR) proteins, segregation data, frequency of the variants in control samples, presence of other pathogenic mutations, and functional and mRNA analyses. While none of these variables can be used alone to predict the significance of UVs in a single case, combined evaluation can lead to clinically useful conclusions. This review reports available information on a sample of MLH1 and MSH2 missense UVs, for which MSI and immunohistochemical data could be retrieved from the literature. Currently, since MSI analysis is routinely performed as a diagnostic test for Lynch syndrome, tumor MSI status represents the most important factor for determining the pathogenicity of UVs in MMR genes.

The authors have designed and implemented a form-based engineering document management system on the basis of an architecture named Formgraphics. The system has full 2-D graphics capabilities that comply with the requirements for highly structured graphics applications. In this sense, the system is typical of new generation graphics facilities. The system's architecture is explained as an instance of a form-based graphics database workbench, its features and function layers are described, and a typical application in software engineering is presented. The system's 3-D graphics processing scheme is also explained, and its applicability to such fields as mechanical and architectural engineering is demonstrated.
Characterization of LQI behavior in WSN for glacier area in Patagonia Argentina (2013)

One of the most important aspects before installing a Wireless Sensor Network (WSN) is a previous study of connectivity constraints that exist in the area to be covered. This study is critical to the final distribution of the sensors, with an important impact in the life of the network by reducing consumption, and on the robustness by contemplating redundancy of paths and sensors. In this paper, we present a summary of the most important aspects of a preliminary empirical study of the Link Quality Indicator (LQI), on different landscapes in the glaciers area of Patagonia Argentina. The landscapes covered varied in geographical structures with different levels of attenuation and extreme environmental conditions. Through the analysis of the Cumulative Distribution Function (CDF) of the measured LQI values, we can characterize the behavior of four different scenarios and correlate the combined effects of the environmental structure with the distance from the transmitter. The measurements performed were designed for characterizing the links at the physical layer with the purpose of defining models to estimate the Packet Error Rate (PER) for the WSN deployment stage.
Compact Merkle Multiproofs (2020)

The compact Merkle multiproof is a new and significantly more memory-efficient way to generate and verify sparse Merkle multiproofs. A standard sparse Merkle multiproof requires to store an index for every non-leaf hash in the multiproof. The compact Merkle multiproof on the other hand requires only $k$ leaf indices, where $k$ is the number of elements used for creating a multiproof. This significantly reduces the size of multirpoofs, especially for larger Merke trees.
