Methods for Creating Semantic Orientation Dictionaries. (2006)

We describe and compare different methods for creating a dictionary of words with their corresponding semantic orientation (SO). We tested how well different dictionaries helped determine the SO of entire texts. To extract SO for each individual word, we used a common method based on pointwise mutual information. Mutual information between a set of seed words and the target words was calculated using two different methods: a NEAR search on the search engine Altavista (since discontinued); an AND search on Google. These two dictionaries were tested against a manually annotated dictionary of positive and negative words. The results show that all three methods are quite close, and none of them performs particularly well. We discuss possible further avenues for research, an d also point out some potential problems in calculating pointwise mutual information using Google. 1.
A successfully treated case of multiple liver abscesses accompanied by portal venous gas. (1996)

A case with multiple liver abscess accompanied by massive portal venous gas is reported. A 61-yr-old male was admitted because of left lower abdominal pain, fever, and diarrhea. Abdominal x-ray examination demonstrated multiple branching lucencies in the liver. Computed tomography revealed multiple liver abscesses and massive gas in the portal system as well as a thickened wall of the sigmoid colon. Enema study using contrast medium revealed a perforation of the sigmoid colon with diverticulitis. The outcome was favorable after sigmoid colectomy in addition to intensive treatment with antibiotics. Bacteroides fragilis, which produces gas (H2 and NH3) by fermentation, was isolated not only from the resected specimen but also from blood samples. Although the presence of portal venous gas is a sign of poor prognosis in patients with intestinal infectious diseases, the sensitive detection of hepatic portal venous gas by computed tomography and the appropriate treatment may improve the patient's prognosis.
Atomic force microscopy characterization of polyethylene terephthalate grafting with poly(styrene sulfonate) (2022)

Polyethylene terephthalate (PET) is widely used to elaborate biomaterials and medical devices in particular for long-term implant applications but tuning their surface properties remains challenging. We investigate surface functionalization by grafting poly(sodium 4-styrene sulfonate, PNaSS) with the aim of enhancing protein adhesion and cellular activity. Elucidating the topography and molecular level organization of the modified surfaces is important for understanding and predicting biological activity. In this work, we explore several grafting methods including thermal grafting, thermal grafting in the presence of Mohr's salt, and UV activation. We characterize the different surfaces obtained using atomic force microscopy (AFM), contact angle (CA), and x-ray photoelectron spectroscopy (XPS). We observe an increase in the percentage of sulfur atoms (XPS) that correlates with changes in (CA), and we identify by AFM characteristic features, which we interpret as patches of polymers on the PET surfaces. This work demonstrates tuning of biomaterials surface by functionalization and illustrates the capability of AFM to provide insights into the spatial organization of the grafted polymer.
Gene Loss, Silencing and Activation in a Newly Synthesized Wheat Allotetraploid (2002)

We analyzed the events that affect gene structure and expression in the early stages of allopolyploidy in wheat. The transcriptome response was studied by analyzing 3072 transcripts in the first generation of a synthetic allotetraploid (genome S(l)S(l)A(m)A(m)), which resembles tetraploid wheat (genome BBAA), and in its two diploid progenitors Aegilops sharonensis (S(l)S(l)) and Triticum monococcum ssp. aegilopoides (A(m)A(m)). The expression of 60 out of 3072 transcripts was reproducibly altered in the allotetraploid: 48 transcripts disappeared and 12 were activated. Transcript disappearance was caused by gene silencing or by gene loss. Gene silencing affected one or both homeologous loci and was associated in part with cytosine methylation. Gene loss or methylation had occurred already in the F(1) intergeneric hybrid or in the allotetraploid, depending on the locus. The silenced/lost genes included rRNA genes and genes involved in metabolism, disease resistance, and cell cycle regulation. The activated genes with a known function were all retroelements. These findings show that wide hybridization and chromosome doubling affect gene expression via genetic and epigenetic alterations immediately upon allopolyploid formation. These events contribute to the genetic diploidization of newly formed allopolyploids.
Pulsed electromagnetic field stimulation of bone marrow cells derived from ovariectomized rats affects osteoclast formation and local factor production (2004)

This study examined the effects of a specific pulsed electromagnetic field (PEMF) stimulation on osteoclast formation in bone marrow cells from ovariectomized rats and to determine if the signal modulates the production of cytokines associated with osteoclast formation. Adult female Wistar rats were subjected to bilateral or sham ovariectomy, and primary bone marrow cells were harvested at 4 days (Subgroup I) and 7 days (Subgroup II) after surgery. Primary bone marrow cells were subsequently placed in chamber slides and set inside solenoids powered by a pulse generator (300 micros, 7.5 Hz) for 1 h per day for 9 days (OVX + PEMF group). Others (INT, SHAM, and OVX groups) were cultured under identical conditions, but no signal was applied. Recruitment and authentication of osteoclast-like cells were evaluated by determining multinuclear, tartrate-resistant acid phosphatase (TRAP) positive cells on day 10 of culture and by pit formation assay, respectively. The PEMF signal caused significant reductions in osteoclast formation in both Subgroups I (-55%) and II (-43%). Tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), and interleukin 6 (IL-6) in OVX + PEMF group of Subgroup I were significantly reduced at 5, 7, and 9 days as compared to OVX group. The results found in this study suggest that osteoclastogenesis can be inhibited by PEMF stimulation, putatively due to a concomitant decrease in local factor production.

Performance comparison of SPT systems integrated with various supercritical CO2-based mixture Brayton cycles based on multi-objective optimization (2019)

The adoption of other gas with supercritical carbon dioxide (S-CO2) cycle is an effective way to improve the performance of the solar power tower plant (SPT). Among various supercritical CO2-based mixture cycles, it is important to select a suitable layout for the SPT system. In this paper, the ability to generate work and compatibility between the thermal storage system and power cycle are investigated simultaneously. First, the effects of key parameters on the system overall exergy efficiency and specific work are discussed separately. Second, the specific work and temperature difference of the thermal storage system are considered simultaneously with the efficiency based on the multi-objective optimization. Finally, the optimal performance of various cycles are compared. The results show that the supercritical CO2-Xe cycles yield excellent performance and present obvious advantages in generating more specific work and good compatibility that compares to the S-CO2 cycles. While adding butane has reverse effects. The inter-cooling and recompression cycles are advantage in exergy efficiency with maximum 34.1% and 33.9%, respectively. The performance comparison of different cycles based on the multi-objective optimization can be helpful in selecting the suitable cycle layout.

Subchromophore interactions in tricyanovinyl-substituted triarylamines—a combined experimental and computational study (1999)

The electronic coupling between the phenyl substituents of mono-, bis-, and tris(tricyanovinyl)-substituted triphenylamines (1, 2, 2-OMe and 3) have been investigated by various methods: the splitting of excited states was taken as a measure of the interaction. These splittings can be seen in the optical absorption spectra; exciton coupling theory was also used to estimate electronic coupling of the excited states; redox potentials gave coupling energies of charged ground state species as well as Hush analysis of intervalence charge-transfer bands (IV-CT), which were observed by UV-Vis-NIR spectroelectrochemistry, and finally, the quadratic hyperpolarisability measured by hyper-Rayleigh scattering was used to estimate excited state couplings. The results of these methods were compared to semiempirical AM1 calculations and suggest the subchromophore interactions to be weak compared to the band width of the UV-spectra. Nevertheless, the quadratic hyperpolarisability is enhanced in the two-dimensional tris(tricyanovinylphenyl)amine compared to its one-dimensional analogue.
Biomechanical mechanisms underlying exosuit-induced improvements in walking economy after stroke (2018)

Stroke-induced hemiparetic gait is characteristically asymmetric and metabolically expensive. Weakness and impaired control of the paretic ankle contribute to reduced forward propulsion and ground clearance - walking subtasks critical for safe and efficient locomotion. Targeted gait interventions that improve paretic ankle function after stroke are therefore warranted. We have developed textile-based, soft wearable robots that transmit mechanical power generated by off-board or body-worn actuators to the paretic ankle using Bowden cables (soft exosuits) and have demonstrated the exosuits can overcome deficits in paretic limb forward propulsion and ground clearance, ultimately reducing the metabolic cost of hemiparetic walking. This study elucidates the biomechanical mechanisms underlying exosuit-induced reductions in metabolic power. We evaluated the relationships between exosuit-induced changes in the body center of mass (COM) power generated by each limb, individual joint power and metabolic power. Compared with walking with an exosuit unpowered, exosuit assistance produced more symmetrical COM power generation during the critical period of the step-to-step transition (22.4±6.4% more symmetric). Changes in individual limb COM power were related to changes in paretic (<i>R</i><sup>2</sup>=0.83, <i>P=</i>0.004) and non-paretic (<i>R</i><sup>2</sup><i>=</i>0.73, <i>P=</i>0.014) ankle power. Interestingly, despite the exosuit providing direct assistance to only the paretic limb, changes in metabolic power were related to changes in non-paretic limb COM power (<i>R</i><sup>2</sup>=0.80, <i>P=</i>0.007), not paretic limb COM power (<i>P></i>0.05). These findings contribute to a fundamental understanding of how individuals post-stroke interact with an exosuit to reduce the metabolic cost of hemiparetic walking.
Microwave irradiation of human brain tissue: production of microscopic slides within one day. (1988)

A three step method using microwave irradiation enabled microscopic slides of human brain tissue to be obtained within one working day: steps 1 and 2 hardened and solidified brain tissue; step 3 completed formalin fixation. The efficacy and precision of the method was compared with slides of conventionally processed brain tissue that had been fixed in formalin for six weeks. The microscopic quality of the sections was excellent with good presentation of brain tissue and equalled that of conventionally processed slides.

THERMAL TEXTURE GENERATION AND 3D MODEL RECONSTRUCTION USING SFM AND GAN (2018)

Abstract. Realistic 3D models with textures representing thermal emission of the object are widely used in such fields as dynamic scene analysis, autonomous driving, and video surveillance. Structure from Motion (SfM) methods provide a robust approach for the generation of textured 3D models in the visible range. Still, automatic generation of 3D models from the infrared imagery is challenging due to an absence of the feature points and low sensor resolution. Recent advances in Generative Adversarial Networks (GAN) have proved that they can perform complex image-to-image transformations such as a transformation of day to night and generation of imagery in a different spectral range. In this paper, we propose a novel method for generation of realistic 3D models with thermal textures using the SfM pipeline and GAN. The proposed method uses visible range images as an input. The images are processed in two ways. Firstly, they are used for point matching and dense point cloud generation. Secondly, the images are fed into a GAN that performs the transformation from the visible range to the thermal range. We evaluate the proposed method using real infrared imagery captured with a FLIR ONE PRO camera. We generated a dataset with 2000 pairs of real images captured in thermal and visible range. The dataset is used to train the GAN network and to generate 3D models using SfM. The evaluation of the generated 3D models and infrared textures proved that they are similar to the ground truth model in both thermal emissivity and geometrical shape.
Anti- Inflammatory Actions of Flavonoids and Structural Requirements for New Design (2008)

Flavonoids are low molecular weight compounds rich in seeds, citrus fruits, olive oil, tea and red wine, with potent antioxidant, cytoprotective and antiinflammatory activities. Flavonoids are composed of a three-ring structure (A,B and C) with various substitutions; they can be subdivided according to the presence of an oxy group at position 4, a double bond between carbon atoms 2 and 3 or a hydroxyl group in position 3 of the C (middle) ring. Particular hydroxylation patterns of the B ring of the flavones permit them to inhibit histamine, tryptase, interleukin-6 and interleukin-8 release from human umbilical-cord derived cultured mast cells, as well as from macrophages. The catechol (o-dihydroxy) group in the B ring as in quercetin confers potent inhibitory ability, while a pyrogallol (trihydroxy) group, as in myricetin, produces even higher activity. However, addition of one hydroxyl group on position 2&#x2032; of the B ring, as in the flavonol morin, renders this compound inactive. The C2-C3 double bond of the C ring appears to increase scavenger activity because it confers stability to the phenoxy-radicals produced, while the 4-oxo (keto double bond at position 4 of the C ring) increases free radical scavenger activity by delocalizing electrons from the B ring. The 3-OH group on the C ring appears tobe critical for anti-inflammatory activity. Inhibition of mast cell secretion was shown to be mediated by a 78-kD phosphoprotein which has been cloned and serves as a bridge between the cell surface and the cytoskeleton. Phosphorylation at particular sites in the C-terminus unfolds the three dimensional structure of this protein making actin binding sites accessible; crosslinking with actin in the cytoskeleton prevents secretion of inflammatory mediators. These properties present unique opportunities for the synthesis of new compounds for the treatment of inflammatory and possibly proliferative disorders.
Experimental performance of a novel aerosol sorting and deposition system for bio-threat sensing applications (2006)

Sarnoff Corporation and the Naval Research Laboratory, through support from HSARPA, are developing an automated, high throughput bio-aerosol physical enrichment system designed for use as part of a biological-threat protection system. The Biological Aerosol-Capture-Enrichment (BioACE) system is a bio-aerosol collection system that combines three unique technologies to create physically enriched aerosol samples that can be subsequently interrogated by any number of bio-threat detection systems for the presence of threat agents. An air-to-air concentrator uses an inertial separation technique to highly concentrate an aerosol sample presented to a dual wavelength ultra-violet laser induced fluorescence (UVLIF) optical trigger used to discriminate potential threat particles from non-threat particles conveyed in a collimated particle stream. This particle classification information is used to trigger an electrostatic deposition mechanism to deposit only those particles determined to be potential bio-threats onto a stainless steel substrate. Non-threat particles are discarded with the exiting airflow. A prototype laboratory system in which particle size dependent elastic scatter rater than fluorescence provides the triggering signal has been experimentally qualified. This paper will present a detailed overview of the prototype system and discuss the physical enrichment results achieved.
Ion velocity and plasma potential measurements of a cylindrical cusped field thruster (2012)

Measurements of the most probable time-averaged axial ion velocities and plasma potential within the acceleration channel and in the plume of a straight-channeled cylindrical cusped field thruster operating on xenon are presented. Ion velocities for the thruster are derived from laser-induced fluorescence measurements of the 5d[4]7/2-6p[3]5/2 xenon ion excited state transition centered at λ=834.72nm. Plasma potential measurements are made using a floating emissive probe with a thoriated-tungsten filament. The thruster is operated in a power matched condition with 300 V applied anode potential for comparison to previous krypton plasma potential measurements, and a low power condition with 150 V applied anode potential. Correlations are seen between the plasma potential drop outside of the thruster and kinetic energy contours of the accelerating ions.
Real frequency technique applied to the synthesis of lumped broad-band matching networks with arbitrary nonuniform losses for MMICs (1988)

A computer-aided synthesis technique for lumped matching networks with arbitrary nonuniform losses is presented. It is especially applicable to the design of broadband amplifiers in MMIC form. A useful theorem and two corollaries for the transformation between lossy and lossless networks are developed, so that the design of the lossy matching networks is considerably simplified and can yield complex models of the lumped elements with arbitrary nonuniform losses. An example showing the application of the method to monolithic broadband amplifier design is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

A multi-stage inversion method for simultaneous source deblending of field data (2014)

Summary Simultaneous source technology has significant impacts on modern seismic acquisition. It allows us to acquire seismic data in a much more efficient way and can play a key role in areas where the acquisition window is rather short, such as the northern seas. A wide range of methods—from processing type to inversion type—have been proposed and studied in order to handle the source interference. Many of those work well on synthetic data but may suffer on field data. Here we propose a multi-stage inversion method, which combines traditional seismic processing with sparse inversion and provides a more target-oriented approach. Each stage of this method focuses on a particular portion of energy in the blended record and separates that from the rest. This method also has a simple and flexible framework, which could potentially combine with other state-of-the-art deblending algorithms. A field trial in the North Sea shows this hybrid approach to be highly successful.
Limonium vigoi (Plumbaginaceae), a new tetraploid species from the Northeast of the Iberian Península (1998)

A new tetraploid agamic species, Limonium vigoi, is described from coastal populations of the Northeast of the Spain (Ebro delta). The new species is related, on morphological grounds, to L. girardianum (Guss.) Fourr. and L. grosii L. Llorens, from which it could be easily discriminated by its retuse leaves, the basal ones usually withered at anthesis, the very short (or even absent) leaf apiculum, the denser and longer (up to 0.7 mm) hairs of the calyx tube and the deeper colour of the corolla. In addition, L. girardianum is triploid, whereas L. vigoi and L. grosii are tetraploid. Limonium girardianum and L. grosii show the same pollen/stigma combination (A/cob type) which differs from that exhibited by L. vigoi (B/papillate type). The types of Limonium girardianum f. retusum Pignatti and L. glaucophyllum Pignatti, two taxa described from the Ebro delta, could not be distinguished from L. girardianum, but they clearly differed from L. vigoi.
