Sol–gel synthesis of carbon-doped TiO2 nanoparticles based on microcrystalline cellulose for efficient photocatalytic degradation of methylene blue under visible light (2019)

Carbon-doped titanium dioxide photocatalyst with improved performance in visible light was prepared via the typical sol-gel method. Microcrystalline cellulose (MCC) was used as carbon elements source. The prepared pure and carbon-doped TiO<sub>2</sub> samples were calcined at 400-650°C in air and the effect of annealing temperature on the stability of carbon ions was investigated. EDX analysis showed the presence of 5.66 wt.% carbon atoms in TiO<sub>2</sub> nanoparticles formed on MCC, which was attributed to the doping of carbon atoms in TiO<sub>2</sub> lattice. Carbon doping was also confirmed by Raman spectroscopy. According to the UV-VIS DRS analysis, the band gap of TiO<sub>2</sub> particles decreased from 2.96 to 2.71 eV in pure and carbon-doped TiO<sub>2</sub>, respectively. Therefore the visible light absorbance increased to 15.05% compared to 0% absorbance in pure TiO<sub>2</sub>. The heat treatment of carbon-doped TiO<sub>2</sub> nanostructures showed that carbon element could escape from the O-Ti-O lattice at temperatures higher than 600°C. According to the SEM images, synthesis of TiO<sub>2</sub> in presence of MCC also limited the growth of TiO<sub>2</sub> nanoparticles and controlled the morphology and aggregation of nanoparticles. Carbon doping improved the photocatalytic performance of TiO<sub>2</sub> photocatalyst compared to the pure nanoparticles in degradation of methylene blue in the aqueous phase. Carbon-doped TiO<sub>2</sub> attained the efficiency of 56.25%, 51.18% and 62.95% under UV, visible and solar lights, respectively, compared to 28.43%, 6.36% and 33.65% related to the pure TiO<sub>2</sub>.

Human Cerebral Microvascular Endothelial Involvement In Neovascularization Of Malignant Glial Tumors (1993)

The detection of tumor DNA in the supernatant of guide sheath flush fluid collected during r-EBUS bronchoscopy represents a sensitive and complementary method for genotyping NSCLC.
Electron irradiation dilatation in SiO2 (1973)

Negative dilatation (shrinkage) induced by 10-keV electron bombardment of SiO2 films thermally grown on Si has been studied. Measured deflection changes in continuous SiO2 bridges etched following irradiation showed a maximum shrinkage of [inverted lazy s] 0.8%, which occurred at 0.2 C/cm2, followed by a slight expansion, and subsequent saturation at higher exposures. Exposures up to 3 C/cm2 were utilized. Isochronal annealing studies show the activation energy for recovery to be approximately 1 eV with 2% recovery occurring in 1 h at 400°C.
Adjunctive Human Papillomavirus Testing in the 2-Year Follow-up of Women With Low-Grade Cervical Cytologic Abnormalities: A Randomized Trial and Economic Evaluation (2003)

Abstract Context. —Although human papillomavirus (HPV) testing may aid in managing low-grade abnormality on screening cervical cytology, patient compliance with repeat testing programs requires consideration. Objectives. —To determine effectiveness and costs of repeated Papanicolaou (Pap) test and oncogenic HPV testing for detecting cervical intraepithelial neoplasia 2 or 3. Design. —We conducted a randomized controlled trial of combined Pap test and cervical HPV testing by Hybrid Capture 1 test compared with Pap test alone; tests were performed every 6 months for up to 2 years. The study end point was colposcopic examination performed on all women at 2 years, or earlier if an HPV test was positive or if a Pap test showed high-grade squamous intraepithelial lesion. Setting. —Sixty-six community family practices. Participants. —Two hundred fifty-seven women with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion on screening cervical cytology. Main Outcome Measures. —Detection of histologically confirmed cervical intraepithelial neoplasia 2 or 3, fully allocated costs, and loss to follow-up. Results. —Combined Pap test and HPV testing detected 11 (100%) of 11 cases of cervical intraepithelial neoplasia 2/3, whereas Pap test alone detected 7 (63.6%) of these 11 cases ( P = .14); corresponding specificities were 39 (46.4%) of 84 and 45 (71.4%) of 63 ( P = .005). The cost-effectiveness ratio was Can $4456 per additional case of high-grade cervical intraepithelial neoplasia. Sixty-nine (26.8%) of the 257 women (24.6% combined group vs 29.1% Pap test only group, P = .41) defaulted from testing or from colposcopy when referred with an abnormal result. Conclusions. —Combined testing was more costly but may detect more cases of cervical intraepithelial neoplasia 2/3 than Pap test alone. However, poor adherence limits usefulness of a management strategy that requires repeated follow-up.

Triazole‐Functionalized Norbornadiene‐Quadricyclane Photoswitches for Solar Energy Storage (2018)

Herein work on 2,3‐substituted norbornadiene‐quadricyclane molecular photoswitches designed for solar energy storage purposes is presented. A series of six new systems bearing 1,4‐ or 1,5‐alkyl triazoles as the acceptor unit combined with various aryl donor groups, as well as four functional intermediates, were synthesized and fully characterized. The new photoswitches were evaluated by measuring optical absorption profiles, activation energies for the thermal conversion of quadricyclanes to norbornadienes, as well as the storage energy densities. These triazoles featured a molar energy storage of 81.2–101 kJ mol –1 corresponding to energy densities of 215–267 kJ kg –1 . The optical absorption profiles exhibited absorption onsets up to 382 nm and a study of the thermally activated conversion from high‐energy quadricyclanes to norbornadienes revealed energy storage half lives of up to 402 days at 25 °C. The modular nature of the “click chemistry” synthesis concept used herein enables access to a large range of compounds with tailored properties such as solubility, thermal half‐life, and solar spectrum match.
Coupling Between Myosin ATPase Cycle and Creatine Kinase Cycle Facilitates Cardiac Actomyosin Sliding In Vitro (1996)

Coupling between the ATPase cycle and the CK cycle may serve not only to maintain the ATP concentration within the myofibril but also to provide optimal conditions for cardiac actomyosin interaction. Consideration of this coupling will offer a clue to elucidating the systolic or diastolic dysfunction during myocardial ischemia or reperfusion.
Texturing of Ga-Doped ZnO Transparent Electrode for a-Si:H Thin Film Solar Cells (2011)

Texturing of Ga-doped ZnO (GZO) was performed for Si thin film solar cell applications using the acetic acid-diluted nitric acid solution. The nitric acid-based texturing solution resulted in rougher surface morphology than the HCl solution that has been generally used as a texturing solution of ZnO-based transparent conductive oxides. The highest solar cell conversion efficiency was achieved using 400 nm-etched GZO film. The short circuit current density and conversion efficiency of the single junction a-Si:H solar cell were improved considerably by as much as 28 and 42%, respectively, compared to those of reference cells.
Fluorescence Correlation Spectroscopy as a Tool to Investigate Single Molecule Probe Dynamics in Thin Polymer Films (2001)

Fluorescence correlation experiments were performed on rhodamine 6G in PDMS spin-coated films on glass surfaces. With polarised excitation, ensemble bleaching of the dye and single molecule intensity fluctuations were observed. From the statistics of single molecule intensity data taken at different positions in the film, correlation functions were calculated. Two modes of motion with exponential decay shapes and correlation times of tau(c) = 0.15 s and tau(c) = 0.7 s could be detected. Potential origins of intensity fluctuations are lateral diffusion, rotational diffusion or intramolecular fluctuations of dyes involving spectral diffusion or photoinduced processes. From the experimental results, lateral diffusion can be ruled out as a motional mode. Single molecule fluctuations are assigned to changes of the molecular configuration of the dyes, which are rigidly bound to the glass. To assess the environmental influence on such molecular motions, the bulk viscosity of the PDMS was varied over two orders of magnitude, leading to changes of tau(c) of the slow mode by a factor of four. This result proves the sensitivity of the single molecule fluctuations to the molecular scale dynamics of the surrounding polymer matrix and makes the correlation time a measure of the local environment of dye probes.
Exploiting Acoustic and Syntactic Features for Automatic Prosody Labeling in a Maximum Entropy Framework (2008)

In this paper, we describe a maximum entropy-based automatic prosody labeling framework that exploits both language and speech information. We apply the proposed framework to both prominence and phrase structure detection within the Tones and Break Indices (ToBI) annotation scheme. Our framework utilizes novel syntactic features in the form of supertags and a quantized acoustic-prosodic feature representation that is similar to linear parameterizations of the prosodic contour. The proposed model is trained discriminatively and is robust in the selection of appropriate features for the task of prosody detection. The proposed maximum entropy acoustic-syntactic model achieves pitch accent and boundary tone detection accuracies of 86.0% and 93.1% on the Boston University Radio News corpus, and, 79.8% and 90.3% on the Boston Directions corpus. The phrase structure detection through prosodic break index labeling provides accuracies of 84% and 87% on the two corpora, respectively. The reported results are significantly better than previously reported results and demonstrate the strength of maximum entropy model in jointly modeling simple lexical, syntactic, and acoustic features for automatic prosody labeling.
Novel Synthetic DNA Immunogens Targeting Latent Expressed Antigens of Epstein–Barr Virus Elicit Potent Cellular Responses and Inhibit Tumor Growth (2019)

Infectious diseases are linked to 15%-20% of cancers worldwide. Among them, Epstein-Barr virus (EBV) is an oncogenic herpesvirus that chronically infects over 90% of the adult population, with over 200,000 cases of cancer and 150,000 cancer-related deaths attributed to it yearly. Acute EBV infection can present as infectious mononucleosis, and lead to the future onset of multiple cancers, including Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal carcinoma, and gastric carcinoma. Many of these cancers express latent viral genes, including Epstein-Barr virus nuclear antigen 1 (<i>EBNA1</i>) and latent membrane proteins 1 and 2 (LMP1 and LMP2). Previous attempts to create potent immunogens against EBV have been reported but generated mixed success. We designed novel Synthetic Consensus (SynCon) DNA vaccines against EBNA1, LMP1 and LMP2 to improve on the immune potency targeting important antigens expressed in latently infected cells. These EBV tumor antigens are hypothesized to be useful targets for potential immunotherapy of EBV-driven cancers. We optimized the genetic sequences for these three antigens, studied them for expression, and examined their immune profiles in vivo. We observed that these immunogens generated unique profiles based on which antigen was delivered as the vaccine target. EBNA1vax and LMP2Avax generated the most robust T cell immunity. Interestingly, LMP1vax was a very weak immunogen, generating very low levels of CD8 T cell immunity both as a standalone vaccine and as part of a trivalent vaccine cocktail. LMP2Avax was able to drive immunity that impacted EBV-antigen-positive tumor growth. These studies suggest that engineered EBV latent protein vaccines deserve additional study as potential agents for immunotherapy of EBV-driven cancers.
DIALIGN-T: An improved algorithm for segment-based multiple sequence alignment (2005)

On BAliBASE, our new program performs significantly better than the previous version of DIALIGN and is comparable to the standard global aligner CLUSTAL W, though it is outperformed by some newly developed programs that focus on global alignment. On the locally related test sets in IRMBASE, our method outperforms all other programs that we evaluated.
Molecular biology of cyanobacterial salt acclimation (2010)

High and changing salt concentrations represent major abiotic factors limiting the growth of microorganisms. During their long evolution, cyanobacteria have adapted to aquatic habitats with various salt concentrations. High salt concentrations in the medium challenge the cell with reduced water availability and high contents of inorganic ions. The basic mechanism of salt acclimation involves the active extrusion of toxic inorganic ions and the accumulation of compatible solutes, including sucrose, trehalose, glucosylglycerol, and glycine betaine. The kinetics of these physiological processes has been exceptionally well studied in the model Synechocystis 6803, leading to the definition of five subsequent phases in reaching a new salt acclimation steady state. Recent '-omics' technologies using the advanced model Synechocystis 6803 have revealed a comprehensive picture of the dynamic process of salt acclimation involving the differential expression of hundreds of genes. However, the mechanisms involved in sensing specific salt stress signals are not well resolved. In the future, analysis of cyanobacterial salt acclimation will be directed toward defining the functions of the many unknown proteins upregulated in salt-stressed cells, identifying specific salt-sensing mechanisms, using salt-resistant strains of cyanobacteria for the production of bioenergy, and applying cyanobacterial stress genes to improve the salt tolerance of sensitive organisms.
Reduced Switching-Frequency Modulation Design for Model Predictive Control Based Modular Multilevel Converters (2019)

This paper proposes a novel switching algorithm for modular multilevel converters (MMCs) that significantly reduces the switching frequency while fulfilling all control objectives required for their proper operation. Unlike in the conventional capacitor voltage-balancing strategies, in addition to submodule (SM) capacitor voltages, the proposed algorithm considers previous switching statuses during sorting. The algorithm is applied to a seven-level back-to-back MMC-HVDC system and tested under various operating conditions. Significant reduction in the switching frequency with trivial impacts on submodule capacitor voltages are observed.
Genetic heterogeneity in attention-deficit hyperactivity disorder (ADHD): Gender, psychiatric comorbidity, and maternal ADHD. (1995)

The authors examined the siblings of 140 attention-deficit hyperactivity disorder (ADHD) and 120 control probands and classified families as antisocial if the proband had conduct disorder or a parent had antisocial personality. Partial support was found for the hypothesis that the ADHD gender effect would be limited to antisocial families. Boys had an increased risk for ADHD compared with girls, but only among siblings from antisocial families. The effect size for predicting ADHD in siblings of probands was greater for maternal compared with paternal ADHD, but only for families exhibiting antisocial disorders. Strong support was found for the hypothesis that, compared with siblings from nonantisocial families, those from antisocial families would have more psychopathology (ADHD, depression, substance use, and conduct disorders). The presence of antisocial disorders signals a distinct subtype of ADHD.
Simple and Principled Uncertainty Estimation with Deterministic Deep\n Learning via Distance Awareness (2020)

Bayesian neural networks (BNN) and deep ensembles are principled approaches\nto estimate the predictive uncertainty of a deep learning model. However their\npracticality in real-time, industrial-scale applications are limited due to\ntheir heavy memory and inference cost. This motivates us to study principled\napproaches to high-quality uncertainty estimation that require only a single\ndeep neural network (DNN). By formalizing the uncertainty quantification as a\nminimax learning problem, we first identify input distance awareness, i.e., the\nmodel's ability to quantify the distance of a testing example from the training\ndata in the input space, as a necessary condition for a DNN to achieve\nhigh-quality (i.e., minimax optimal) uncertainty estimation. We then propose\nSpectral-normalized Neural Gaussian Process (SNGP), a simple method that\nimproves the distance-awareness ability of modern DNNs, by adding a weight\nnormalization step during training and replacing the output layer with a\nGaussian process. On a suite of vision and language understanding tasks and on\nmodern architectures (Wide-ResNet and BERT), SNGP is competitive with deep\nensembles in prediction, calibration and out-of-domain detection, and\noutperforms the other single-model approaches.\n
Optimal Power Splitting for Simultaneous Information Detection and\n Energy Harvesting (2017)

This letter deals with the joint information and energy processing at a\nreceiver of a point-to-point communication channel. In particular, the\ntrade-off between the achievable information rate and harvested energy for a\nmultiple-antenna power splitting (PS) receiver is investigated. Here, the rate-\nenergy region characterization is of particular interest, which is\nintrinsically a non-convex problem. In this letter, an efficient algorithm is\nproposed for obtaining an approximate solution to the problem in polynomial\ntime. This algorithm is mainly based on the Taylor approximation in conjunction\nwith semidefinite relaxation (SDR) which is solved by interior-point methods.\nMoreover, we utilize the Gaussian randomization procedure to obtain a feasible\nsolution for the original problem. It is shown that by proper receiver design\nthe rate-energy region can be significantly enlarged compared to the state of\nthe art, while at the same time the receiver hardware costs is reduced by\nutilizing less number of energy harvesting circuitry.\n
Satellite Image Time Series Analysis Under Time Warping (2012)

Satellite Image Time Series are becoming increasingly available and will continue to do so in the coming years thanks to the launch of space missions which aim at providing a coverage of the Earth every few days with high spatial resolution. In the case of optical imagery, it will be possible to produce land use and cover change maps with detailed nomenclatures. However, due to meteorological phenomena, such as clouds, these time series will become irregular in terms of temporal sampling, and one will need to compare time series with different lengths. In this paper, we present an approach to image time series analysis which is able to deal with irregularly sampled series and which also allows the comparison of pairs of time series where each element of the pair has a different number of samples. We present the dynamic time warping from a theoretical point of view and illustrate its capabilities with two applications to real-time series.

Определены иммунохимические характеристики антител, изучено взаимодействие рекомбинантных иммуноглобулинов со штаммами вируса гриппа А подтипов H1N1 и H3N2. Показано, что рекомбинантные варианты FI6 IgA-изотипа проявляют, как и исходное антитело, специфичность в отношении всех исследуемых штаммов. При этом наибольший уровень связывания достигается для подтипа H1N1, относящегося к гемагглютининам филогенетической группы I
Kinetics and mechanism of oxidation of SiGe: dry versus wet oxidation (1989)

The rates of oxidation of SiGe and of Si covered with a thin ‘‘marker’’ of Ge have been measured, and compared with rates of oxidation for pure Si, both for wet and dry ambient. It is shown that the presence of Ge at the SiO2/Si interface increases the rate of wet oxidation by a factor of about 2.5, while it does not affect the rate of dry oxidation. By decreasing the partial pressure of H2O sufficiently, the rate of wet oxidation can be decreased to match that of dry oxidation. In this case again, Ge has no effect on the rate. Contrary to what has been proposed before, Ge is being piled up at the interface both for fast and slow oxidation. We demonstrate that the role of Ge is to suppress the formation of Si interstitials and that this is the rate limiting step in cases of rapid oxidation. For slower oxidation, interstitials have considerably more time to diffuse away and thus their formation and/or diffusion is not rate limiting.
