A Versatile Parameterization for Measured Material Manifolds (2018)

Abstract A popular approach for computing photorealistic images of virtual objects requires applying reflectance profiles measured from real surfaces, introducing several challenges: the memory needed to faithfully capture realistic material reflectance is large, the choice of materials is limited to the set of measurements, and image synthesis using the measured data is costly. Typically, this data is either compressed by projecting it onto a subset of its linear principal components or by applying non‐linear methods. The former requires many components to faithfully represent the input reflectance, whereas the latter necessitates costly extrapolation algorithms. We learn an underlying, low‐dimensional non‐linear reflectance manifold amenable to rapid exploration and rendering of real‐world materials. We can express interpolated materials as linear combinations of the measured data, despite them lying on an inherently non‐linear manifold. This allows us to efficiently interpolate and extrapolate measured BRDFs, and to render directly from the manifold representation. We exploit properties of Gaussian process latent variable models and use our representation for high‐performance and offline rendering with interpolated real‐world materials.
Short-Term Case Reports Demonstrating the Use of Volume-Stable Collagen Matrix. (2021)

A proper diagnostic and treatment planning process for dental implant rehabilitations should include a checklist of key factors to help clinicians avoid potential complications. Such a checklist should encompass evaluation of the soft- and hard-tissue volume buccal to each implant, as this has been shown to aid in maintaining marginal bone levels long-term. Thus, as part of surgical planning, a decision to augment the soft tissue should be considered. The autogenous palatal graft has long been considered the "gold standard" for soft-tissue augmentation; however, the benefits of this approach should be weighed against the potential complications associated with a secondary surgical site as well as the patient's desire for as pain-free an experience as possible. The volume-stable collagen matrix (VSCM) is a promising material with favorable healing characteristics and volume thickness maintenance of up to 3 years in current literature. This article presents two cases that demonstrate the clinical advantages of a VSCM over the use of autogenous palatal grafts as part of the authors' "10 Keys" principles of augmenting the volume and thickness of peri-implant tissues.

Enhanced Striatal NR2B-Containing N -Methyl- d -Aspartate Receptor-Mediated Synaptic Currents in a Mouse Model of Huntington Disease (2004)

Huntington disease (HD) is an inherited neurodegenerative disease caused by expansion of a polyglutamine tract near the N terminus of the protein huntingtin, leading to dramatic loss of striatal medium-sized spiny GABAergic projection neurons (MSNs). Evidence suggests overactivation of N-methyl-D-aspartate (NMDA)-type glutamate receptors (NMDARs) contributes to selective degeneration of MSNs in HD. Striatal MSNs are enriched in NR2B, and whole cell current and excitotoxicity mediated predominantly by the NR2B subtype of NMDARs is increased with expression of mutant huntingtin in transfected cell lines and striatal MSNs from mice models. To test whether synaptic NMDAR current is altered by mutant huntingtin expression, we recorded striatal MSN excitatory postsynaptic currents (EPSCs) evoked by stimulation of cortical afferents in corticostriatal slices from YAC72 mice and their wild-type (WT) littermates at age 21-31 days. The ratio of NMDAR- to AMPAR-mediated EPSC amplitude was significantly increased in YAC72 compared to WT mice. Furthermore, using a paired-pulse stimulation protocol as a measure of presynaptic glutamate release probability, we found no significant differences between YAC72 and WT striatal MSN responses. These data suggest selective potentiation of postsynaptic NMDAR activity at corticostriatal synapses in YAC72 mice. Measurements of EPSC decay kinetics, as well as the effects of NR2B-subtype selective antagonists and glycine concentration on EPSC amplitude, are consistent with the majority of postsynaptic NMDARs being triheteromers of NR1/NR2A/NR2B in both WT and YAC72 mice. Together with previous results, our data suggest that enhanced activity of NR2B-containing NMDARs is one of the earliest changes leading to neuronal degeneration in HD.
Covered stents: A 25‐year odyssey (2019)

The concept of the PTFE-covered stent was introduced 25 years ago in the treatment of an aneurysmal vein graft. The study by Pavani et al. represents the largest cohort of patients treated with covered stents for Ellis type 3 perforations. Covered stents are effective in treating coronary perforations and remain an invaluable tool in the cardiac catheterization lab.

The generic position of Lebeckia microphylla E. Mey. has been subject to differing taxonomic interpretations. Previously the species has also been described as Krebsia argentea Eckl. & Zeyh. [Krebsia Eckl. & Zeyh. is now a section of Lotononis (DC.) Eckl. & Zeyh.] and later as Buchenroedera glabriflora N.E. Br. and B. uniflora Dümmer. Based on new evidence, this species is shown to be better placed in Lotononis section Krebsia. The new combination Lotononis caerulescens (E. Mey.) B-E. van Wyk is made. Die generiese posisie van Lebeckia microphylla E. Mey. is onderhewig aan verskillende taksonomiese interpretasies. Voorheen is die spesie ook al beskryf as Krebsia argentea Eckl. & Zeyh.

Aan die hand van nuwe getuienis word aangetoon dat die spesie meer tuis hoort in Lotononis seksie Krebsia. Die nuwe kombinasie Lotononis caerulescens (E. Mey.) B-E. van Wyk word gemaak.
<title>Feasibility of scatterometers with new geometrical concepts</title> (1995)

Two new geometrical concepts of scatterometer were investigated in order to reduce the variation of incidence angle on the fore and aft beams. The first one has fore, aft and mid beams nearly parallel and directed across the satellite track. The second one has concentric fore and aft beams. A feasibility study was undertaken to estimate system performances and budget in C band. This study begins with the determination of radiometric resolution requirement from a wind retrieval simulation in order to take into account the variation of azimuth angle along the beams. Finally performances and interface budgets are compared with currently developed systems.
Electronic gJFactors, Natural Lifetimes, and Electric Quadrupole Interaction for Rb87in the np2P3/2Series of the Rb I Spectrum (1971)

For Rb 87 the level crossing method was applied to the first four levels ( n = 5, 6, 7, and 8) of the np 2 P 3/2 series in the Rb I spectrum. By using magnetic dipole interaction constants from corresponding zero field optical double resonance experiments, the electronic g J factors of 5, 6, and 7 p 2 P 3/2 were calculated from the level crossing data. For these levels the natural radiative lifetimes were determined from the half-widths of the level crossing signals. For 8 p 2 P 3/2 the a factor was obtained assuming g J = -1.336 (2). From the measured electric quadrupole interaction constants b , decreasing values of the nuclear quadrupole moment Q were obtained in 5, 6, 7, and 8 p 2 P 3/2 . When core polarization effects are taken into account, the different 2 P 3/2 levels yield consistent values for the quadrupole moment. We find g J (5 p 2 P 3/2 ) = -1.3362 (6) g J (6 p 2 P 3/2 ) = -1.3347 (10) τ (5 p 2 P 3/2 ) = 25.8 (8) ns τ (6 p 2 P 3/2 ) = 111 (3) ns b (5 p 2 P 3/2 ) = 12.510 (57) MHz b (6 p 2 P 3/2 ) = 3.947 (13) MHz Q (5 p 2 P 3/2 ) = 0.131 barn Q (6 p 2 P 3/2 ) = 0.133 barn g J (7 p 2 P 3/2 ) = -1.3359 (11) a (8 p 2 P 3/2 ) = 6.747 (14) MHz τ (7 p 2 P 3/2 ) = 233 (10) ns b (8 p 2 P 3/2 ) = 0.933 (20) MHz b (7 p 2 P 3/2 ) = 1.768 (8) MHz Q (8 p 2 P 3/2 ) = 0.131 barn Q (7 p 2 P 3/2 ) = 0.133 barn Considering possible sources of error in the evaluation of the quadrupole moment we obtain Q (Rb 87 ) = +0.132 (9) barn.
Saturation Transfer Difference 1D-TOCSY Experiments to Map the Topography of Oligosaccharides Recognized by a Monoclonal Antibody Directed Against the Cell-Wall Polysaccharide of Group AStreptococcus (2002)

A new saturation transfer difference 1D-TOCSY NMR experiment that allows the investigation of complex ligands interacting with proteins and its application in the mapping of which portions of oligosaccharide ligands (epitope) interact with a complementary antibody are described. The interaction between trisaccharide and hexasaccharide ligands, corresponding to fragments of the cell-wall polysaccharide of Streptococcus Group A, and a monoclonal antibody directed against the polysaccharide is investigated at the molecular level. The polysaccharide consists of alternating alpha-(1-->2) and alpha-(1-->3) linked L-rhamnopyranose (Rha) residues with branching N-acetyl-D-glucopyranosylamine (GlcNAc) residues linked beta-(1-->3) to alternate rhamnopyranose rings. The epitope is proven to consist not only of the immunodominant GlcNAc sugar but also of an entire branched trisaccharide repeating unit. The experimental NMR data serve to check and validate the computed models of the oligosaccharide-antibody complexes.
Can Cotton (Cossypium hirsutum) Seed Vigor Be Assessed in the Absence of Growth (1989)

Although seed vigor is ultimately expressed in terms of growth, it is not clear if metabolic processes unlinked to growth can also estimate vigor. The objective of this study was to determine if the relationship between seed vigor and ethanol metabolism differed depending on whether seed growth was presence or absence. For individua1 imbibed cotton seed, ethanol assimilation in air and ethanol biosynthesis in N₂ gas was correlated to seed vigor as measured by cool test performance. Seed growth in N₂ gas was prevented by the addition of polyethylene glycol. Results were inconclusive, because seed performance (radicle growth) during cool testing was not significantly correlated to either ethanol biosynthesis or ethanol assimilation. It was concluded that ethanol metabolism both in the absence and presence of seed growth has limited usefulness as a metabolic marker of cotton seed vigor.
An Anisotropy of Gain in N2-Laser Pumped GaAs under Applied Electric Field (1977)

In the temperature range 80∼130 K, stimulated emission from N2-laser pumped GaAs under an electric field has been observed and the anisotropy of the net gain for the polarity of the field has been found. The obtained maximum difference in the net gain in our experiments was 17 cm-1 for applied field of 1.5 kV/cm at 130 K. The anisotropy of the net gain increased with temperature for the same field intensity and rapidly increased with increasing electric field over the threshold value of about 1 kV/cm. The origin of the anisotropy of the net gain has been qualitatively understood by the unidirectional laser action, caused by the drifting motion of carriers in a semiconductor.
Alleviating self-interference in MANETs (2004)

The interference range in multi-hop ad hoc networks (MANETs) is typically twice as large as the transmission range. This phenomenon causes packets of a multi-hop flow to interfere with each other as they are relayed over the multi-hop route. This interference, an instance of the notorious hidden terminal problem, is caused by simultaneous transmissions by down-stream nodes unaware of ongoing transmissions by up-stream nodes. DMAC (deferrable MAC) is a novel MAC protocol that alleviates the hidden terminal problem by deferring further transmissions until the previously transmitted packets travel far enough to avoid interference with the newly transmitted packets. For simple chain topologies, DMAC improves the throughput of CBR and TCP flows by up to 100% and 60%, respectively. For random mobile topologies with up to 40 simultaneous flows, DMAC improves the throughput of TCP flows by up to 30%.
Cyclostationarity-based Algorithm for Blind Recognition of OFDM and Single Carrier Linear Digital Modulations (2007)

The paper studies the cyclostationarity of an orthogonal frequency division multiplexing (OFDM) with a view to recognizing OFDM against single carrier linear digital (SCLD) modulations. The analytical expressions for the nth-order cyclic cumulants (CCs) and cycle frequencies of an OFDM signal embedded in additive white Gaussian noise and subject to phase, frequency and timing offsets are derived An algorithm based on a second-order CC is proposed to recognize OFDM against SCLD modulations. The recognition algorithm of the authors obviates the need for preprocessing tasks, such as symbol timing estimation, carrier and waveform recovery, and signal and noise power estimation. The results of simulation experiments confirm the theoretical analysis.

Wide spectral range confocal microscope based on endlessly single-mode fiber (2010)

We report an endlessly single mode, fiber-optic confocal microscope, based on a large mode area photonic crystal fiber. The microscope confines a very broad spectral range of excitation and emission wavelengths to a single spatial mode in the fiber. Single-mode operation over an optical octave is feasible. At a magnification of 10 and λ = 900 nm, its resolution was measured to be 1.0 μm (lateral) and 2.5 μm (axial). The microscope's use is demonstrated by imaging single photons emitted by individual InAs quantum dots in a pillar microcavity.
High Resolution Consensus Mapping of Quantitative Trait Loci for Fiber Strength, Length and Micronaire on Chromosome 25 of the Upland Cotton (Gossypium hirsutum L.) (2015)

Cotton (Gossypium hirsutum L.) is an important agricultural crop that provides renewable natural fiber resources for the global textile industry. Technological developments in the textile industry and improvements in human living standards have increased the requirement for supplies and better quality cotton. Upland cotton 0-153 is an elite cultivar harboring strong fiber strength genes. To conduct quantitative trait locus (QTL) mapping for fiber quality in 0-153, we developed a population of 196 recombinant inbred lines (RILs) from a cross between 0-153 and sGK9708. The fiber quality traits in 11 environments were measured and a genetic linkage map of chromosome 25 comprising 210 loci was constructed using this RIL population, mainly using simple sequence repeat markers and single nucleotide polymorphism markers. QTLs were identified across diverse environments using the composite interval mapping method. A total of 37 QTLs for fiber quality traits were identified on chromosome 25, of which 17 were stably expressed in at least in two environments. A stable fiber strength QTL, qFS-chr25-4, which was detected in seven environments and was located in the marker interval between CRI-SNP120491 and BNL2572, could explain 6.53%-11.83% of the observed phenotypic variations. Meta-analysis also confirmed the above QTLs with previous reports. Application of these QTLs could contribute to improving fiber quality and provide information for marker-assisted selection.
In Vitro Assessment of the Cytotoxic, Apoptotic, and Mutagenic Potentials of Isatin (2013)

Isatin (1H-indole-2,3-dione) is a chemical found in various medicinal plant species and responsible for a broad spectrum of pharmacological and biological properties that may be beneficial to human health, as an anticonvulsant, antibacterial, antifungal, antiviral, and anticancer agent. The aim of the present study was to determine in vitro the cytotoxic, mutagenic, and apoptotic effects of isatin on CHO-K1 and HeLa cells using the MTT viability assay (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide), micronucleus (MN) test, apoptosis index, and nuclear division index (NDI). The 5 isatin concentrations evaluated in the mutagenicity and apoptosis tests were 0.5, 1, 5, 10, and 50 μM, selected through a preliminary MTT assay. Positive (doxorubicin, DXR) and negative (phosphate buffered saline, PBS) control groups were also included in the analysis. Isatin did not exert a mutagenic effect on CHO-K1 after 3 and 24 h of treatment or on HeLa cells after 24 h. However, 10 and 50 μM concentrations inhibited cell proliferation and promoted apoptosis in both CHO-K1 and HeLa cells. Data indicate that the cytotoxic, apoptotic, and antiproliferative effects of isatin were concentration independent and cell line independent.
Neural Network-Based Abstract Generation for Opinions and Arguments (2016)

We study the problem of generating abstractive summaries for opinionated text. We propose an attention-based neural network model that is able to absorb information from multiple text units to construct informative, concise, and fluent summaries. An importance-based sampling method is designed to allow the encoder to integrate information from an important subset of input. Automatic evaluation indicates that our system outperforms state-of-the-art abstractive and extractive summarization systems on two newly collected datasets of movie reviews and arguments. Our system summaries are also rated as more informative and grammatical in human evaluation.
Vemurafenib in the French temporary authorization for use metastatic melanoma cohort (2013)

Vemurafenib, a selective BRAF inhibitor, has recently shown an improved overall survival (OS) in metastatic melanoma with V600E mutation in phase 2 and 3 trials. Patients with BRAF V600E metastatic melanoma received vemurafenib orally, in the French temporary authorization for use program from April 2011 to April 2012. We analysed the clinical benefit and safety of vemurafenib. Secondary analyses included the impact of brain metastases on median OS and progression-free survival (PFS). Fifty patients were enrolled, of whom 20% had stage IIIC and 80% stage IV disease. The majority were men (58%), with a median age of 58 years (51-69). Forty-three patients had an Eastern Cooperative Oncology Group performance status of 0 or 1 (86%). Twenty patients had brain metastases (40%). Overall response rate was 53%. Complete response was achieved in five patients (10%), partial response in 21 patients (43%) and stable disease in seven patients (14%). Median OS was 7.5 months (95% confidence interval 5.6-12.7) and PFS was 3.6 months (95% confidence interval 2.9-5.9). Patients with brain metastasis had a response rate of 50% (nine partial response, one complete response), and median OS and PFS were, respectively, 4.3 and 3.1 months. Common adverse events were fatigue, arthralgia and cutaneous side effects. Sixteen per cent developed squamous cell carcinoma. Grade 3/4 was observed in 11 patients (22%). Six per cent required temporary discontinuation and/or dose reduction because of toxic effects. This study confirms the considerable clinical benefit of vemurafenib for patients with brain metastasis, with manageable toxicity.

Observation of Positive Effects of Freestanding Scattering Film in Dye-Sensitized Solar Cells (2009)

Dye-sensitized solar cells (DSSCs) with a nanocrystalline TiO2 as a anode incorporating a free-standing and flexible light-scattering film composed of sub-micrometer-sized Al2O3 particles with a small amount of ion-transportable polymeric binder were prepared and compared to DSSCs composed of a nanocrystalline TiO2/sub-micrometer-sized TiO2 bilayer as an anode. The cell efficiency of the former was higher than that of the latter. This implies that the enhancement of the light absorption as that obtained with a general DSSC with light-scattering layer (sub-micrometer-sized TiO2) is possible by combining a high-surface-area layer of nanocrystalline TiO2 and free-standing light scattering film. The novel DSSCs with the free-standing light scattering film showed an additional resistance, which was characterized by the electrochemical impedance analysis. However, the cell performance was not seriously influenced by the additional resistance. When the free-standing scattering film was assembled with flexible type DSSCs, not only a greatly enhanced power conversion efficiency but also better long-term stability than the DSSC without the light scattering film were observed.
Amplification in Extended Transmission Bands Using Bismuth-Doped Optical Fibers (2012)

Bismuth-doped optical glasses emit NIR luminescence in an ultrabroad spectral region of 1000-2000 nm. It makes Bi-doped glasses and glass optical fibers a promising active medium for the creation of Bi-doped fiber lasers and broadband optical amplifiers for this spectral region. Since the first fabrication of Bi-doped fibers in 2005 a large number of papers devoted to the development of Bi-doped fiber lasers and optical amplifiers have been published. It has been shown that Bi-doped fibers are a new breakthrough in active laser materials.
