Document-Word Co-regularization for Semi-supervised Sentiment Analysis (2008)

The goal of sentiment prediction is to automatically identify whether a given piece of text expresses positive or negative opinion towards a topic of interest. One can pose sentiment prediction as a standard text categorization problem, but gathering labeled data turns out to be a bottleneck. Fortunately, background knowledge is often available in the form of prior information about the sentiment polarity of words in a lexicon. Moreover, in many applications abundant unlabeled data is also available. In this paper, we propose a novel semi-supervised sentiment prediction algorithm that utilizes lexical prior knowledge in conjunction with unlabeled examples. Our method is based on joint sentiment analysis of documents and words based on a bipartite graph representation of the data. We present an empirical study on a diverse collection of sentiment prediction problems which confirms that our semi-supervised lexical models significantly outperform purely supervised and competing semi-supervised techniques.
Asymmetric Bioreduction of Alkenes Using Ene–Reductases YersER and KYE1 and Effects of Organic Solvents (2011)

Asymmetric trans-bioreduction of activated alkenes by KYE1 from Kluyveromyces lactis and Yers-ER from Yersinia bercovieri, two ene-reductases from the Old Yellow Enzyme family, showed a broad substrate spectrum with a moderate to excellent degree of stereoselectivity. Both substrate- and enzyme-based stereocontrols were observed to furnish opposite stereoisomeric products. The effects of organic solvents on enzyme activity and stereoselectivity were outlined in this study, where two-phase systems hexane and toluene are shown to sustain bioreduction efficiency even at high organic solvent content.
Outer-Membrane Vesicles Released by Normally Growing Escherichia coli Contain Very Little Lipoprotein (1981)

The lipoprotein content of the outer-membrane medium vesicles, which are released from Escherichia coli during normal growth, was compared to the lipoprotein content of the corresponding cellular outer membranes. It was found that the medium vesicles contained only 35% free lipoprotein and almost none of the bound lipoprotein when compared with cellular outer membranes. Medium vesicles also had reduced amounts of protein II and a protein V (Mr = 16 000), while they contained large amounts of pore-forming proteins I and lamB. A mechanism is proposed in which outer membrane vesicles are formed when the outer membrane expands faster than the underlying peptidoglycan layer. The lack or enrichment of individual proteins in medium vesicles may be determined by their interactions with the peptidoglycan-bound lipoprotein complex.
Mitral Annulus Flattens in Ischemic Mitral Regurgitation: Geometric Differences Between Inferior and Anterior Myocardial Infarction (2005)

Mitral annulus flattens in ischemic MR. Deformity of the mitral annulus was greater in anterior MI group than in the inferior MI group.
Introduction of Fatty Acids to Starch Granules by Ultra-High-Pressure Treatment (1998)

Introduction of fatty acid into maize starch granule by ultra high pressure treatment (UHPT) was investigated. Starches are normal, waxy and amylo-species. They were treated by ball-mill before UHPT. Fatty acids are linoleic, oleic and oleic-stearic acid mixtures. Removal of oil on granule surface was done with 50% ethanol. The incorporated amount of fatty acids and tendency of effect of ball-mill time on the fatty acid amount are different among the three starch species. Fatty acid introduction to amylose and amylopectin helices was also investigated after washing with chloroform-methanol-water mixture. The introduced fatty acid amount to amylostarch is the largest among three species. It is proved that the less double bond in fatty acid, the more fatty acid introduced to starch. The peak at 13.6° (2T) on X-ray diffraction pattern of starch samples treated by UHP becomes large and their Tp on DSC becomes low as increase of introduced fatty acid.
A novel synthesis of the isoxazolo[5,4,3‐<i>kl</i>]acridine ring system (1990)

Abstract The Schmidt reaction of 6,7‐dihydro‐3‐phenyl‐1,2‐benzisoxazol‐4(5 H )‐one ( 1 ) is described. In addition to the expected isomeric lactams, 3‐phenyl‐5,6,7,8‐tetrahydro‐4 H ‐isoxazolo[4,5‐ c ]azepin‐4‐one ( 3 ) and 7,8‐dihydro‐3‐phenyl‐4 H ‐isoxazolo[4,5‐ b ]azepin‐5(6 H )‐one ( 4 ), 4‐amino‐3‐phenyl 1,2‐benzisoxazole (5) was isolated, along with 4,5‐dihydro‐3 H ‐isoxazolo[5,4,3‐ kl ]acridine ( 6 ). Possible mechanisms for the formation of these products are discussed and some chemistry of the little‐known ring system represented by 6 is also described.
REACTION OF AMINO ALCOHOLS WITH CARBON DISULPHIDE (1958)

ω-Amino alcohols possessing five or more methylene units between the amino and hydroxyl groups on condensation with carbon disulphide gave good yields of 1,3-di-(ω-hydroxyalkyl) thioureas. These symmetrically disubstituted thioureas on oxidation gave the corresponding 1,3-di-(ω-hydroxyalkyl) ureas.
Studies on Tropolone Derivatives Having Monoamine Oxidase Inhibitory Activity (1988)

The inhibitory potency towards monoamine oxidase (MAO : EC 1.4.3.4) was assayed for 33 species of tropolone related compounds. The tropolne skeleton itself had hardly participated in MAO inhibitory action, while the functional groups had affected the potency of the compounds. Azulene, a hydrocarbon with unsubstituted 5- and 7-carbon rings, inhibited MAO in the mouse liver competitively, and its IC50 was 59.0μM. The inhibition constants (K1) of azulene for MAO in the mouse liver was 12.5 μM.
Monocular dense reconstruction by depth estimation fusion (2018)

Dense and accurate reconstruction plays a fundamental role in mobile robot's environment perception and navigation. It's also necessary for obstacle avoidance and path planning of mobile robots. We propose a method to incrementally reconstruct the scene from monocular sequence by fusing the depth from geometry computation and generative adversarial networks (GAN) prediction. The depth from geometry triangulation is precise but sparse, while the depth from GAN is dense but unscaled. In this paper, we combine the advantages from two methods with a linear model optimized by graph structure. Experiments showed that our proposed method gives precise dense reconstruction in real time.

Correlations between 31P-NMR spectroscopy and tissue O2 tension measurements in a murine fibrosarcoma. (1989)

Size-dependent changes in therapeutically relevant and interrelated metabolic parameters of a murine fibrosarcoma (FSaII) were investigated in vivo using conscious (unanesthetized) animals and tumor sizes less than or equal to 2% of body weight. Tumor pH and bioenergetics were evaluated by 31P nuclear magnetic resonance spectroscopy (31P-MRS), and tumor tissue oxygen tension (pO2) distribution was examined using O2-sensitive needle electrodes. During growth FSaII tumors showed a progressive loss of phosphocreatine (PCr) and nucleoside triphosphate (NTP) with increasing inorganic phosphate (Pi) and phosphomonoester (PME) signals. Ratios for PCr/Pi, PME/Pi, NTP/Pi, and phosphodiester/inorganic phosphate (PDE/Pi) as well as pH determined by 31P-NMR (pHNMR) and the mean tissue pO2 progressively declined as the tumors increased in size. The only relevant ratio increasing with tumor growth was PME/NTP. When the mean tissue pO2 value was plotted against pHNMR, NTP/Pi, PCr/Pi, PME/Pi, and PDE/Pi for tumor groups of similar mean volumes, a highly significant positive correlation was observed. There was a negative correlation between mean tumor tissue pO2 values and PME/NTP. From these results we concluded that 31P-MRS can detect changes in tumor bioenergetics brought about by changes in tumor oxygenation. Furthermore, the close correlation between oxygenation and energy status suggests that the microcirculation in FSaII tumors yields an O2-limited energy metabolism. Finally, a correlation between the proportion of pO2 readings between 0 and 2.5 mmHg and the radiobiologically hypoxic cell fraction in FSaII tumors was observed. The latter finding might be of particular importance for radiation therapy.
New mechanism of the mode coupling in multi-core fiber lasers (2008)

We present the first experimental demonstration of strong coupling between the core modes in multi-core fibers (MCF) regardless of large spacing (~28μm) between them. The effect is very sensitive to bending of the fiber and is observed in the MCF laser as well as in the probe beam schemes. We explain the observed effect by a mechanism of the mode coupling based on their indirect interaction inside the fiber via intermediate cladding mode, analogues to the Bragg mode. 70% of power conversion from one core to another with beating length of tens of centimeters in 4-core MCF is measured.
The effect of age on protein metabolism (2000)

The mechanisms of senescence remain to be fully defined. This review focuses on recent advances in our understanding of body protein turnover, which is essential for the remodeling of tissues and production of specific proteins in time of need. Recent advances in technology make it possible to measure the synthesis rate of muscle myosin heavy chain, mitochondrial proteins and sarcoplasmic proteins, providing insight into the mechanisms of the sarcopenia of aging. A reduced synthesis rate of myosin heavy chain and mitochondrial protein may explain muscle weakness and fatiguability that occurs with aging. Aging also seems to affect selected liver proteins such as fibrinogen. The potential roles of exercise and hormone replacement in slowing the age-related decline in protein turnover is discussed.
Tuning of the Size of Dy<sub>2</sub>O<sub>3</sub> Nanoparticles for Optimal Performance as an MRI Contrast Agent (2008)

The transverse 1H relaxivities of aqueous colloidal solutions of dextran coated Dy2O3 nanoparticles of different sizes were investigated at magnetic field strengths (B) between 7 and 17.6 T. The particle size with the maximum relaxivity (r2) appears to vary between 70 nm at 7 T (r2 approximately = 190 s(-1) mM(-1)) and 60 nm at 17.6 T (r2 approximately = 675 s(-1) mM(-1)). A small difference between r2 and r2* was observed, which was ascribed to the effect of the dextran coating. The value of r2 is proportional to B2 up to 12 T after which it saturates. Independent magnetization measurements on these particles at room temperature at magnetic field strengths up to 30 T, however, show a typical paramagnetic behavior with a magnetization of the particle that is proportional to the field strength. The saturation in the curve of r2 as a function of B2 was tentatively explained by the presence of an extremely fast relaxing component of the signal at high field strengths, which is not observable on the NMR time scale. The results of this study can be exploited for the rational design of MRI contrast agents, based on lanthanide oxide particles, with high efficiencies at magnetic field strengths of more than 1.5 T.
Cost-Effectiveness of Laboratory Testing (2003)

The demand for proving the value of newer and more expensive medical technologies, including newer medical tests, will increase substantially. Payers, including Medicare, commercial insurers, and employers, will demand accountability and elimination of the abuse and misuse of ineffective testing strategies. Pathologists and laboratorians play a key role in guiding the most cost-effective use of testing strategies, including the judicious use of algorithms.

A nonlinear equalization algorithm for single-carrier block transmission systems (2014)

Combating the intersymbol interference is an important issue in single-carrier block transmission systems. In this paper, we present a nonlinear equalizer that combines frequency-domain (FD) pre-filtering with time-domain tree search detection. Simulation results show that the proposed algorithm achieves a detection performance that is very close to that of the conventional tree search equalizer (which employs the QRD-M algorithm), but with a much lower complexity. In addition, the proposed algorithm performs significantly better than the linear equalizers and decision-feedback equalizers, with only a modest increase in complexity.
A phase 3 trial of local chemotherapy with biodegradable carmustine(BCNU) wafers (Gliadel wafers) in patients with primary malignant glioma (2003)

A previous placebo-controlled trial has shown that biodegradable 1,3-bis (2-chloroethyl)-1-nitrosourea (BCNU) wafers (Gliadel wafers) prolong survival in patients with recurrent glioblastoma multiforme. A previously completed phase 3 trial, also placebo controlled, in 32 patients with newly diagnosed malignant glioma also demonstrated a survival benefit in those patients treated with BCNU wafers. Because of the small number of patients in that trial, a larger phase 3 trial was performed to confirm these results. Two hundred forty patients were randomized to receive either BCNU or placebo wafers at the time of primary surgical resection; both groups were treated with external beam radiation postoperatively. The two groups were similar for age, sex, Karnofsky performance status (KPS), and tumor histology. Median survival in the intent-to-treat group was 13.9 months for the BCNU wafer-treated group and 11.6 months for the placebo-treated group (log-rank P -value stratified by country = 0.03), with a 29% reduction in the risk of death in the treatment group. When adjusted for factors affecting survival, the treatment effect remained positive with a risk reduction of 28% ( P = 0.03). Time to decline in KPS and in 10/11 neuroperformance measures was statistically significantly prolonged in the BCNU wafer-treated group ( P </= 0.05). Adverse events were comparable for the 2 groups, except for CSF leak (5% in the BCNU wafer-treated group vs. 0.8% in the placebo-treated group) and intracranial hypertension (9.1% in the BCNU wafer-treated group vs. 1.7% in the placebo group). This study confirms that local chemotherapy with BCNU wafers is well tolerated and offers a survival benefit to patients with newly diagnosed malignant glioma.
The geometry of ROC space: understanding machine learning metrics through ROC isometrics (2003)

Many different metrics are used in machine learning and data mining to build and evaluate models. However, there is no general theory of machine learning metrics, that could answer questions such as: When we simultaneously want to optimise two criteria, how can or should they be traded off? Some metrics are inherently independent of class and misclassification cost distributions, while other are not — can this be made more precise? This paper provides a derivation of ROC space from first principles through 3D ROC space and the skew ratio, and redefines metrics in these dimensions. The paper demonstrates that the graphical depiction of machine learning metrics by means of ROC isometrics gives many useful insights into the characteristics of these metrics, and provides a foundation on which a theory of machine learning metrics can be built. 1.
Acyclic Phosphonomethylether Nucleoside Inhibitors of Respiratory Viruses (1997)

A series of acyclic phosphonomethylether nucleosides were synthesized and then evaluated for inhibitory activity against respiratory viruses of clinical significance using CPE inhibition, neutral red uptake and virus yield reduction assays. Of the 20 compounds synthesized, none significantly inhibited influenza A or B viruses or respiratory syncytial virus strains A2, Long or 18537; the selective indices (SI) were less than 10. A new compound, GS-2128 (2R, 5R-9-[2,5-dihydro-5-(phosphonomethoxy)-2-furanyl]adenine; D4API), selectively inhibited adenovirus 5 (SI>10) as did GS-0577 (9-(3-hydroxy-2-phosphonylmethoxypropyl)-adenine; HPMPA) and GS-0504 [(S)-1-[3-hydroxy-2-(phosphonylmethoxypropyl)]-cytosine; HPMPC]. The 50% effective concentrations (EC 50 ) ranged from 8–100 μg mL −1 and 50% cell inhibitory concentrations (CC 50 ) from 40–1000 μg mL −1 . All three compounds were also found to be active against laboratory strains and clinical isolates of adenovirus types 1, 2, 8 and 41 with EC 50 values ranging from 0.2 to 10 μg mL −1 . Two compounds, GS-438 (9-(2-phosphonylmethoxyethyl)guanine, PMEG) and GS-2542 (9-[3-phosphonomethoxy)methoxymethyl]guanine) inhibited parainfluenza virus 3 strain C243, with SI of 52 and >333, respectively. PMEG also inhibited measles virus strains CC, Halonen and Chicago with EC 50 values ranging from 0.03–9 μg mL −1 . These data suggest that these compounds should be considered for possible development as therapeutic agents for respiratory virus infections.
