Joint Effects of Smoking and Sedentary Lifestyle on Lung Function in African Americans: The Jackson Heart Study Cohort (2014)

This study examined: (a) differences in lung function between current and non current smokers who had sedentary lifestyles and non sedentary lifestyles and (b) the mediating effect of sedentary lifestyle on the association between smoking and lung function in African Americans. Sedentary lifestyle was defined as the lowest quartile of the total physical activity score. The results of linear and logistic regression analyses revealed that non smokers with non sedentary lifestyles had the highest level of lung function, and smokers with sedentary lifestyles had the lowest level. The female non-smokers with sedentary lifestyles had a significantly higher FEV1% predicted and FVC% predicted than smokers with non sedentary lifestyles (93.3% vs. 88.6%; p = 0.0102 and 92.1% vs. 86.9%; p = 0.0055 respectively). FEV1/FVC ratio for men was higher in non smokers with sedentary lifestyles than in smokers with non sedentary lifestyles (80.9 vs. 78.1; p = 0.0048). Though smoking is inversely associated with lung function, it seems to have a more deleterious effect than sedentary lifestyle on lung function. Physically active smokers had higher lung function than their non physically active counterparts.
A major portion of the latent pseudorabies virus genome is transcribed in trigeminal ganglia of pigs (1990)

Pseudorabies virus (PRV) is a porcine herpesvirus that establishes latent infections in trigeminal ganglia. To determine whether PRV expresses any transcripts that could play a role in latency, the trigeminal ganglia of 14 pigs previously inoculated through the nose and latently infected with PRV(Ka) were assayed by in situ nucleic acid hybridization for the presence of PRV-specific RNA. Hybridizations employing probes encompassing the entire viral genome revealed that an area extending from 0.64 to 0.82 map units was transcriptionally active. The DNA probe that most consistently detected transcripts was BamHI-8, a fragment which contains the gene for the immediate-early protein. With this probe, ganglia from 10 (71%) of 14 pigs scored positive for PRV RNA, although only 1 (8%) of 12 of the ganglia from the opposite side reactivated virus after explanation and culture of latently infected trigeminal ganglia. The RNA was transcribed from the strand opposite to that coding for the immediate-early protein; the signal was neuronally localized, with dense nuclear accumulation accompanied by variable numbers of grains over the cytoplasm. Northern RNA blot analysis showed that a discrete set of poly(A)- PRV transcripts were present in latently infected trigeminal ganglia. Additional in situ nucleic acid hybridization analysis revealed that the 3' limit of the transcriptionally active area was located in a 1.2-kilobase fragment upstream and adjacent to the 5' end of the immediate-early protein RNA, whereas the 5' limit was as much as 4.9 kilobases downstream from the 3' end of this RNA. PRV therefore expresses latent-phase transcripts that, although similar in many respects to latent-phase transcripts reported for other herpesviruses, have some unique properties.
Por una izquierda de los movimientos: el 15-M como espejo y como modelo (2011)

Estas lineas recogen que es lo que, desde el punto de vista del autor, deberia ser la izquierda. En ellas se elude una discusion tan farrragosa como necesaria - la relativa a las virtudes y desventajas del termino izquierda - al tiempo que se toma, en muchos sentidos, como modelo lo que supone el Movimiento del 15 de mayo de los indignados. Este se ha convertido en un referente material al que vincular muchas ideas, y en singular la de que movimientos como el son realidades plenas.
Worldwide SOFC Technology Overview and Benchmark (2005)

Solid oxide fuel cells (SOFC) are generally considered to be a promising future electricity‐generation technology due to their high electrical efficiency. They also display a multi‐fuel capability (hydrogen, carbon monoxide, methane, etc.), may play a role in carbon sequestration strategies, and may render the highest electricity generation efficiency in power station design if coupled with a gas turbine. Nevertheless, their development still faces various problems with high‐temperature materials, design of cost‐effective materials and manufacturing processes, and efficient plant design. This article summarizes world wide efforts in the field of SOFC, presenting an overview of the main SOFC designs and the main developers active in this field. Based on data published in proceedings of international conferences during the last few years, a comparison is made of the results achieved in cell, stack, and system development.
Piezoeffect and gate current in AlGaN/GaN high electron mobility transistors (1997)

We report on a high positive turn-on voltage (close to 2.5 V) of the gate-source leakage current in AlGaN/GaN high electron mobility transistors (HEMTs). The piezoeffect, the barrier, and channel doping result in the electron sheet concentration as high as 1013 cm−2. A larger conduction band discontinuity and a larger electron effective mass (compared to AlGaAs/GaAs HEMTs) lead to a lower gate current and to a higher turn-on voltage. This means that AlGaN/GaN technology can be suitable for applications in digital and mixed-mode integrated circuits.
A high quality lead-free (Li, Ta) modified (K, Na)NbO<sub>3</sub>single crystal and its complete set of elastic, dielectric and piezoelectric coefficients with macroscopic 4mm symmetry (2014)

A high quality orthorhombic (K, Na, Li)(Nb, Ta)O3 single crystal with a large size of 9 × 9 × 11 mm3 was successfully grown using the top-seeded solution growth method. Its large size allowed us to perform comprehensive investigation on this crystal. A complete set of elastic, dielectric and piezoelectric coefficients was determined using combined resonance and ultrasonic methods. The longitudinal piezoelectric coefficient d33 and the transverse piezoelectric coefficient d31 of this lead-free piezoelectric single crystal are as high as 354 pC N−1 and −163 pC N−1, respectively, which are two times higher than those of KNN-TL ceramics and are comparable with those of PZT5. The electromechanical coupling factor k33 is as high as 82%, much higher than those of KNN-TL ceramics and PZT5. The coefficient d33,strain was found to be as high as 672 pm v−1 and the extrinsic contribution (~22%) was investigated by Rayleigh analysis. These high piezoelectric properties make this single crystal a promising candidate for replacing lead-based piezoelectric materials.
Characterization of the anaerobic propionate-degrading syntrophs Smithella propionica gen. nov., sp. nov. and Syntrophobacter wolinii (1999)

A strain of anaerobic, syntrophic, propionate-oxidizing bacteria, strain LYPT (= OCM 661T; T = type strain), was isolated and proposed as representative of a new genus and new species, Smithella propionica gen. nov., sp. nov. The strain was enriched from an anaerobic digestor and isolated. Initial isolation was as a monoxenic propionate-degrading co-culture containing Methanospirillum hungateii JF-1T as an H2- and formate-using partner. Later, an axenic culture was obtained by using crotonate as the catabolic substrate. The previously described propionate-degrading syntrophs of the genus Syntrophobacter also grow in co-culture with methanogens such as Methanospirillum hungateii, forming acetate, CO2 and methane from propionate. However, Smithella propionica differs by producing less methane and more acetate; in addition, it forms small amounts of butyrate. Smithella propionica and Syntrophobacter wolinii grew within similar ranges of pH, temperature and salinity, but they differed significantly in substrate ranges and catabolic products. Unlike Syntrophobacter wolinii, Smithella propionica grew axenically on crotonate, although very slowly. Co-cultures of Smithella propionica grew on propionate, and grew slowly on crotonate or butyrate. Syntrophobacter wolinii and Syntrophobacter pfennigii grow on propionate plus sulfate, whereas Smithella propionica did not. Comparisons of 16S rDNA genes indicated that Smithella propionica is most closely related to Syntrophus, and is more distantly related to Syntrophobacter.
Multi-channel optical coupling between VCSEL arrays and multimode optical fibers for a 40-channel parallel optical interconnection module (2002)

We have successfully developed some new assembly techniques for the prototype ParaBIT module to provide the efficient and uniform multi-channel optical coupling between VCSEL/photodiode arrays and multimode optical fibers. The modules which were assembled by using these techniques satisfied the restriction on the optical coupling variation of 1.5 dB.
Vaccination with human tyrosinase DNA induces antibody responses in dogs with advanced melanoma. (2006)

Antitumor immune responses can be elicited in preclinical mouse melanoma models using plasmid DNA vaccines encoding xenogeneic melanosomal differentiation antigens. We previously reported on a phase I clinical trial of human tyrosinase (huTyr) DNA vaccination of 9 dogs with advanced malignant melanoma (World Health Organization stages II-IV), in which we demonstrated the safety of the treatment and the prolongation of the expected survival time (ST) of subjects as compared to historical, stage-matched controls. As a secondary goal of the same study, we report here on the induction of tyrosinase-specific antibody responses in three of the nine dogs vaccinated with huTyr DNA. The antibodies in two of the three responders cross-react with syngeneic canine tyrosinase, demonstrating the ability of this vaccine to overcome host immune tolerance and/or ignorance to or of "self" antigens. Most interestingly, the onset of antibody induction in these three dogs coincides with observed clinical responses and may suggest a means to account for their long-term tumor control and survival.
A CMOS Data Transfer System Based on Planar RF Coupling for Reinforced Galvanic Isolation with 25-kV Surge Voltage and 250-kV/µs CMTI (2020)

This paper exploits an effective approach to overcome the breakdown limitations of traditional galvanic isolators based on chip-scale isolation barriers, thus achieving a very high isolation rating (i.e., compliant with the reinforced isolation requirements). Such an approach is based on radio frequency (RF) planar coupling between two side-by-side co-packaged chips. Standard packaging along with proper assembling techniques can be profitably used to go beyond 20-kV surge voltage without using expensive or exotic isolation components. As a proof of concept, a bidirectional data transfer system based on RF planar coupling able to withstand an isolation rating as high as 25 kV has been designed in a low-cost standard 0.35-µm CMOS technology. Experimental measurements demonstrated a maximum data rate of 40 Mbit/s using a carrier frequency of about 1 GHz. The adopted approach also guarantees a common mode transient immunity (CMTI) of 250 kV/µs, which is a first-rate performance in view of next generation galvanic isolators for wide-bandgap power semiconductor devices, such as gallium nitride high-electron mobility transistors (GaN HEMTs) and silicon carbide (SiC) MOSFETs.
Tocopherol and tocotrienol homologs in parenteral lipid emulsions (2014)

The information on the types and quantity of vitamin E homologs in various lipid emulsions will be extremely useful to physicians and healthcare personnel in selecting appropriate lipid emulsions that are exclusively used in patients with inadequate gastrointestinal function, including hospitalized and critically ill patients. Some emulsions may require vitamin E supplementation in order to meet minimal human requirements.
Excellent performance of Pt0 on high nitrogen-containing carbon nanotubes using aniline as nitrogen/carbon source, dispersant and stabilizer (2010)

Novel high nitrogen-containing carbon nanotubes (NC-CNT) (14% N) as catalyst support have been successfully prepared using aniline as a dispersant to CNT and as a source for both carbon and nitrogen coated on the surface of the CNT.
SIMPLE DEVICES FOR EFFECTIVE ARTIFICIAL RESPIRATION IN EMERGENCIES (1913)

In a preliminary note,<sup>1</sup>about a year ago, I described a simple method of artificial respiration which proved efficient in animals. The method consisted in driving air rhythmically by bellows through a tube which has been introduced into the pharynx. The plan of this method was based on the following considerations. Air under pressure in the pharynx has four outlets. It may escape by way of the nasopharynx through the nose. It may escape through the mouth. It may escape through the esophagus into the stomach. It may finally enter into the trachea and the lungs; when it enters there with sufficient force, it causes an inspiration. To obtain an efficient insufflation of air from the pharynx into the lungs, the other exits must be satisfactorily barricaded. In the method described under the name of pharyngeal insufflation the escape of air through the mouth was effectively reduced by pressure
The Effect of Bi-Terminal PEGylation of an Integrin α<sub>v</sub>β<sub>6</sub>–Targeted<sup>18</sup>F Peptide on Pharmacokinetics and Tumor Uptake (2015)

The bi-PEGylated radiotracer 5 showed a greatly improved pharmacokinetic profile, beyond what was predicted from individual N- or C-terminal PEGylation. It appears that the 2 PEG units acted synergistically to result in an improved metabolic profile including high αvβ6+ tumor uptake and retention.
X-ray Measurements of Surface Residual Stresses in Cold Rolled α-Brass (1970)

Abstract Residual elastic stresses have been measured in cold rolled α-brass (30% zinc) using the available x-ray diffractometer methods. Residual stress values obtained by the two exposure and sin 2 ψ methods of stress analysis are compared with data obtained using Wagner's extrapolation method. For deformations up to 50% reduction in thickness, tensile surface stresses prevailed, and in most cases could be detected by these methods. Uncertainty of the value of a 0 , the lattice parameter of the deformed' material, presents a serious limitation to the extrapolation technique. Using the approximation a 0 = a 0 ann , residual stresses appear lower than, and frequently of opposite sign to those given by the two exposure method. In addition, lattice parameter variations in the near surface regions of the rolled sheet were opposite to those expected from the true macrostress distributions shown to exist by the two exposure method and by strain gauge techniques. The distributions of a hkl points in the extrapolation plots were in agreement with theory for a combination of anisotropic elastic stresses and low stacking fault density.
Chinese handwriting quality evaluation based on analysis of recognition confidence (2011)

Handwriting is one of the major activities in everybody's life. In order to let people form good habit of writing, handwriting quality evaluation is an important and useful technology. In this paper, a method of Chinese handwriting quality evaluation is proposed based on analysis of online Chinese handwriting recognition confidence. For a given handwritten Chinese character, we firstly calculate the confidence level by the candidate distance obtained from the modified quadratic discriminant function (MQDF) classifier. Then the Chinese handwriting quality is evaluated according to different recognition confidence measurement levels. Experimental results show that the proposed method is reasonable and effective.
Using active and passive RFID technology to support indoor location-aware systems (2008)

Emerging mobile technologies are being applied successfully in cultural spaces to help users to get the correct information no matter where he is, in such a way that their use result better than traditional guides. Different technologies (RFID, Wi-Fi, etc.) are applied to allow mobile devices, such as PDAs or smart phones, interact with their environment in order to provide users with updated information regarding his physical location. This paper describes a system environment based on both active and passive RFID technology which supports the automatic positioning of mobile devices in closed spaces. This proposal results especially useful to provide location-aware information avoiding the need for users to manually select the desired information they want to view. This proposal has been successfully proved for the location and positioning of PDAs.
Reinforcement of siloxane elastomers by silica. Interactions between an oligomer of poly(dimethylsiloxane) and a fumed silica (1979)

Abstract The study of the adsorption of an organosiloxane onto a fumed silica was undertaken in order to improve our knowledge of the reinforcement of silicon rubbers by silica. IR and gas‐phase chromatography techniques were used to characterize the adsorption of octamethyltetracyclosiloxane. At room temperature, the occurrence of hydrogen bonding between the solute and the adsorbent was shown. The amount of material adsorbed according to this mechanism was shown to be strongly dependent on temperature. The heats of adsorption at various covering ratios were calculated from the isotherms measured at temperatures close to 150°C.

Response times have been also compared, highlighting the positive effects played by Pt additions.
Rapid and label‐free bacteria detection by surface plasmon resonance (SPR) biosensors (2009)

Surface Plasmon Resonance (SPR) biosensor technology has been successfully used for the detection of various analytes such as proteins, drugs, DNA, and microorganisms. SPR-based immunosensors that coupled with a specific antigen-antibody reaction, have become a promising tool for the quantification of bacteria as it offers sensitive, specific, rapid, and label-free detection. In this paper, we review the important issues in the development of SPR-based immunoassays for bacteria detection, concentrating on instrumentation, surface functionalization, liquid handling, and surface regeneration. In addition, this review touches on the recent advances in SPR biosensing for sensitivity enhancement.

Visualization of putting trajectories in live golf broadcasting (2019)

We developed a system for visualizing golf putting trajectories that can be used in live broadcasting. The trajectory computer graphics (CGs) in a golf putting scene are useful for visualizing the results of past plays and the shape of the green. In addition, displaying past trajectories that were shot near the position of the next player helps TV viewers predict the ball movement of the next play. Visualizing the putting trajectories in this way offers TV viewers a new style of watching live golf tournaments and helps make the programs more understandable and exiting.
Laurenditerpenol, a New Diterpene from the Tropical Marine Alga <i>Laurencia </i><i>i</i><i>ntricata</i> that Potently Inhibits HIF-1 Mediated Hypoxic Signaling in Breast Tumor Cells (2004)

The degree of tumor hypoxia correlates with advanced disease stages and treatment resistance. The transcription factor hypoxia-inducible factor-1 (HIF-1) promotes tumor cell adaptation and survival under hypoxic conditions. Therefore, specific HIF-1 inhibitors represent an important new class of potential tumor-selective therapeutic agents. A T47D human breast tumor cell-based reporter assay was used to examine extracts of plants and marine organisms for inhibitors of HIF-1 activation. Bioassay-guided fractionation of the lipid extract of the red alga Laurencia intricata yielded a structurally novel diterpene, laurenditerpenol (1). The structure of 1 was determined spectroscopically. The relative configurations of the substituents of each ring system were assigned on the basis of NOESY correlations. The absolute configuration of position C-1 was determined by the modified Mosher ester procedure (directly in NMR tubes). Compound 1 potently inhibited hypoxia-activated HIF-1 (IC50: 0.4 microM) and hypoxia-induced VEGF (a potent angiogenic factor) in T47D cells. Compound 1 selectively inhibits HIF-1 activation by hypoxia but not iron chelator-induced activation. Further, 1 suppresses tumor cell survival under hypoxic conditions without affecting normoxic cell growth. Compound 1 inhibits HIF-1 by blocking the induction of the oxygen-regulated HIF-1alpha protein. Mitochondrial respiration studies revealed that 1 suppresses oxygen consumption.
