A New Method of Estimation of the Optimal AV Delay by Using Pulse Oximetry in DDD Paced Patients (1998)

The paper gives a detailed description of a new method for estimating the optimal AV delay in dual chamber paced patients, which is non-invasive, not dependent on the examinator, not time consuming and inexpensive. In principle, the pulse oximetry signal obtained by common finger probe was used to measure the change in its time course after changes in pacemaker stimulation. The Eagle 4000 monitor, manufactured by Marquette USA, was used for measurements and digitizing the data and then this data was analyzed using a portable personal computer with original programs developed in Famulus v. 3.5. Our results were compared to the standard method for optimizing AV delay which uses the direct measurement of blood pressure in the ascending aorta. Twenty-four patients with Physios pacemakers were enrolled in the pilot study. Measurements showed a positive correlation (r = 0.982, N = 432) between the changes in the pulse oximetry amplitude and changes in the pressure pulse amplitude measured in the ascending aorta by a catheter-tip manometer. These results indicated that this new method could be a possible alternative to the currently used techniques for AV interval optimization.
Efficient Copper-Catalyzed S-Vinylation of Thiols with Vinyl Halides (2011)

The synthesis of vinyl sulfides through the coupling reaction of thiols with vinyl iodides, bromides, and chlorides is described. The thiols can couple with aryl iodides in the presence of only 0.5 mol % Cu(2)O without the need for an ancillary ligand. In the presence of 5 mol % of Cu(2)O and 10 mol % 1,10-phenanthroline as the ligand, the more challenging alkyl vinyl bromides can also be coupled with thiols, giving the vinyl sulfides in good to excellent yields.
Dynamic Response Analysis of Tailings Dam under Seismic Action (2015)

A finite element model of tailiings dam was used to analyze the dynamic responses of the stress field, displacement and acceleration of the dam with the dynamic time-history response analysis method in this paper. The time-history curves of different responses were obtained. And an evaluation for dynamic stability of the tailings dam was also discussed. The analysis result shows that this case can provide a certain reference value for the dynamic calculation and the dynamic stability analysis of tailings dam under seismic load.

Die Teilhabe des Betroffenen an der Aphasierehabilitation am Beispiel der Aphasie-Therapiechronik (2011)

In einer internationalen Befragung von Aphasie-Selbsthilfeorganisationen (ASHO) gaben 26 Organisationen Auskunft uber deren Grose, Aufbau, Personal, Finanzierung, Leistungsangebote und Kooperationen mit dem professionellen System (Lauer 2010). Es zeigt sich, dass die Anzahl der Mitglieder und die Finanzierungsmoglichkeiten deutlich variieren. Am haufigsten finanzieren sich die ASHO uber Spenden, offentliche Gelder und Mitgliederbeitrage. Die meisten ASHO sehen die Beratung von Betroffenen und Angehorigen sowie die Offentlichkeitsarbeit zur Erhohung des Bekanntheitsgrads der Aphasie und ihrer Folgen in der Bevolkerung als ihre Hauptanliegen. In vielen Fallen kooperieren die ASHO mit professionellen Helfern verschiedener Rehabilitationsstadien und halten diese Kooperation fur einen wichtigen Bestandteil ihrer Tatigkeit. Der Artikel gibt eine Ubersicht zu den Ergebnissen der Befragung und vergleicht diese abschliesend mit der Situation der Aphasie-Selbsthilfe in Deutschland.
Local Binary Pattern Descriptors for Dynamic Texture Recognition (2006)

Dynamic texture is an extension of texture to the temporal domain. In this paper, a new method for recognizing dynamic textures is proposed. The textures are modeled with concatenated local binary patterns in three orthonormal planes. The circular neighborhoods are generalized to elliptical sampling to fit to the space-time statistics. This is an extension of the LBP approach widely used in still texture analysis, combining the motion and appearance together. Our approach has many advantages compared with the earlier approaches providing a better performance for the DynTex and MIT databases.
Influence of Instrument Parameters on Nonspectroscopic Interferences in Inductively Coupled Plasma-Mass Spectrometry (1987)

The effect of ion lens voltage settings and plasma conditions on nonspectroscopic interferences has been studied. The change in ion count rate for 7 Li, 10 B, 45 Sc, and 89 Y in the presence of Na, K, Sr, and Cs under a variety of experimental conditions is reported. The ion lens voltage setting did not affect the degree of nonspectroscopic interferences with the use of the Einzel ion optic system. Suppression effects were increased when the power was increased and the sampling depth decreased. Changes in nebulizer pressure resulted in interference trends, which varied with the concomitant element being studied. Sodium caused a decrease in interference effects with increasing nebulizer pressure, whereas Cs caused an increase under the same experimental conditions. Suppression of analyte ion count rate increased with increasing sample solution uptake rate and increasing atomic mass of concomitant elements.
Experimental Evaluation of Ethanolic Extract of <i>Carapa guianensis</i> L. Leaf for Its Wound Healing Activity Using Three Wound Models (2009)

The leaves of Carapa guianensis have been used to treat ulcers, skin parasites, and skin problems. The ethanolic extract of C. guianensis leaf was evaluated for its antibacterial and wound healing activity using excision, incision and dead space wound models in rats. The animals were randomly divided into two groups (n = 6) in all the models. In the excision wound model test group animals were treated topically with the leaf extract (250 mg kg(-1) body weight) whereas, control animals were treated with petroleum jelly. In the incision and dead space wound models, the test group animals were treated with extract (250 mg kg(-1) day(-1)) orally by mixing in drinking water and the control group animals were maintained with plain drinking water. Healing was assessed by the rate of wound contraction, period of epithelialization, skin breaking strength, granulation tissue weight and hydoxyproline content. On Day 15 extract-treated animals exhibited 100% reduction in the wound area when compared to controls (95%) with significant decrease in the epithelialization period. The extract failed to demonstrate antibacterial activity. Skin breaking strength (P < .001), wet (P < .002) and dry (P < .02) granulation tissue and hydroxyproline content (P < .03) were significantly higher in extract treated animals. The increased rate of wound contraction, skin breaking strength and hydroxyproline content supports potential application of C. guianensis in wound healing.
Snapback Breakdown Dynamics and ESD Susceptibility of LDMOS (2006)

LDMOS transistors are widely used as output drivers in multiple applications in smart power IC designs. Relative to their sizes, LDMOS transistors are inherently weak with respect to ESD reliability and enhancing their ESD robustness has been an on-going challenge for many years. Snapback breakdown in MOSFET devices has been widely employed to explain the device failures due to ESD. A figure depicts a typical I-V characteristic and the testing device leakage evolution for a MOSFET device subject to transmission-line-pulse (TLP) ESD stress. For most conventional MOSFET devices, the first snapback breakdown, defined I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t1</sub> and V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t1</sub> , is not a threat to the device until it reaches its thermal limit, I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">t2</sub> . For most LDMOS cases, however, the first snapback breakdown can lead to the device damage. It has been broadly accepted that non-uniform snapback breakdown leads to current filamentation/crowding, which leads to excessive heating and failure. For a given type of LDMOS, two different failure modes are observed, which is dependent upon the effective gate width. A description and explanation of the different failure mechanisms due to these effects on the devices with different geometry is provided

Adenosine Receptor A1 Regulates Polymorphonuclear Cell Trafficking and Microvascular Permeability in Lipopolysaccharide-Induced Lung Injury (2010)

Extracellular adenosine and adenosine receptors are critically involved in various inflammatory pathways. Adenosine receptor A1 (A1AR) has been implicated in mediating transmigration of leukocytes to sites of inflammation. This study was designed to characterize the role of A1AR in a murine model of LPS-induced lung injury. LPS-induced transmigration of polymorphonuclear cells (PMNs) and microvascular permeability was elevated in A1AR(-/-) mice. Pretreatment of wild-type mice with the specific A1AR agonist 2'Me-2-chloro-N6-cyclopentyladenosine attenuated PMN accumulation in the interstitium and alveolar space as well as microvascular permeability. Lower PMN counts in the lungs of pretreated wild-type mice were associated with reduced amounts of the chemotactic cytokines TNF-α, IL-6, and CXCL2/3 in the bronchoalveolar lavage. Pretreatment was only effective when A1AR was expressed on hematopoietic cells as demonstrated in chimeric mice. These findings were confirmed by in vitro transmigration assays demonstrating that chemokine-induced transmigration of PMNs was reduced when PMNs but not when pulmonary endothelial or alveolar epithelial cells were pretreated. 2'Me-2-chloro-N6-cyclopentyladenosine prevented pulmonary endothelial but not epithelial cells from LPS-induced cellular remodeling and cell retraction. Our data reveal what we believe to be a previously unrecognized distinct role of A1AR for PMN trafficking and endothelial integrity in a model of acute lung injury.
Human Effigy Pipes from Spiro Mound, Leflore County, Oklahoma (2001)

Animal and human effigy tobacco pipes are not uncommon in Middle and Lower Mississippi culture sites, but are often rather crudely worked. However, the five human figurine pipes found during the University of Oklahoma - Works Project Administration excavation of the Spiro Mound are unusually perfect specimens of primitive stone sculpture and represent relatively finished examples of prehistoric art. The accompanying pen and ink sketches of these pipes give a general idea of the artistry they represent.

Evaluation of anti-microbial and anti-inflammatory activity of Morinda tinctoria Roxb. (2010)

This study is aimed to assess the anti-microbial and anti-inflammatory effects of Morinda tinctoria Roxb MTR (Nunaa). The antimicrobial property of the MTR was studied against Gram-positive and Gram-negative microorganisms using the agar disc diffusion method, in which methanolic leaf extract of (MTR) has shown bigger zone of inhibition (15 – 20 mm) than aqueous leaf extract (MTR) (10–17 mm). The anti-inflammatory effect was evaluated in carrageenin-induced rat paw edema model. The methanolic and aqueous extracts of MTR was administered orally (p.o.) at 200mg/kg. Pretreatment with a single dose of MTR produced significant dose-dependent anti-inflammatory effects on carrageenin-induced rat hind paw edema. Crude methanolic and aqueous extract (200 mg/kg) and indomethacin (5 mg/kg) inhibited significantly (p < 0.05) the formation of the carrageenin-induced rat paw edema, measured in third hour of experiment (peak of edema formation) by 65.21%, 62.31% and 71.01%, respectively. These results demonstrate that MTR possesses anti-microbial and antiinflammatory effects and has no obvious acute toxicity, which advanced our understanding of the folk use of MTR in treating various inflammatory disorders.
Controlled Nanoparticle Metal Phosphates (Metal=Al, Fe, Ce, and Sr) Coatings on LiCoO[sub 2] Cathode Materials (2005)

Despite the fact that the same coating concentration and annealing temperature are used for MPO4 nanoparticle coatings (M = Al, Fe, Ce, and SrH) on a LiCoO2 cathode, the extent of the coating coverage is influenced by the nanoparticle size or morphology. Nanoparticles (AlPO 4 or FePO4) with a size smaller than 20 nm led to the complete encapsulation of LiCoO2, but those with sizes greater than 150 nm (CePO4) or with whisker shapes (SrHPO4) led to partial encapsulation. This difference affected the discharge capacity. The LiCoO2 completely encapsulated with AlPO4 or FePO 4 showed the highest discharge capacity of 230 mAh/g at 4.8 and 3 V at a rate of 0.1 C (=18 mA/g), which diminished with decreasing coating coverage in the order of Al ∼ Fe < SrH < Ce < bare cathode. However, the capacity retention during cycling increased in the order of Al > Ce > SrH > Fe > bare cathode. This is consistent with the capacity retention result obtained at 90°C storage for 4 h.

TIMP1 and MMP9 are predictors of mortality in septic patients in the emergency department and intensive care unit unlike MMP9/TIMP1 ratio: Multivariate model (2017)

It could be argued that plasma levels of TIMP1 should be considered as a promising prognostic biomarker in the setting of sepsis. Additionally, this study, like other studies with large numbers of septic patients does not support the predictive value of TIMP1 / MMP9.
Assessment of Surface Wettability and its Relation to Boiling Phenomena (2001)

Abstract The methods for evaluating surface wettability during boiling phenomena are reviewed. Surface wettability strongly affects boiling phenomena such as boiling nucleation, bubble growth and departure, evaporation near the three phase contact line and so on. Consequently, in most regions of boiling curves other than the fully-developed film boiling regime, surface wettability has strong effects on boiling curves. In order to evaluate surface wettability, the equilibrium contact angle measured at room temperature has been commonly used. In this paper, the authors describe evidence that indicates that the equilibrium contact angle is not sufficient to estimate surface wettability as a parameter in boiling phenomena. Some other indexes of surface wettability, such as advancing and receding contact angle, dynamic contact angle, surface energy, and potential energy scale between liquid & solid molecules are reviewed and discussed.
Noncoordinated expression of luteal cell messenger ribonucleic acids during human chorionic gonadotropin stimulation of the primate corpus luteum (1993)

In nonfertile cycles, the absolute steroidogenic capacity of the primate corpus luteum, as reflected in the expression of messenger RNA (mRNA) for the progesterone biosynthetic enzymes cytochrome P450 cholesterol side-chain cleavage (P450SCC) and 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD), progressively declines until luteal regression. Despite this progressive loss in luteal cell function, the elaboration of CG by the implanted blastocyst is able to prolong the functional lifespan of the corpus luteum. It was the purpose of this study to investigate the relationship between aging of the primate corpus luteum and the cellular mechanisms by which the decline in luteal cell function is arrested by CG. Corpora lutea were obtained from cynomolgus monkeys on days 11 or 16 of the luteal phase after a 7-day treatment period with increasing doses of human CG (hCG) given intramuscularly beginning on days 5 or 10. Corpora lutea were also obtained from control animals on days 5, 10, 11, and 16 of the luteal phase. Human CG treatment significantly (P < 0.05) elevated both serum progesterone and estradiol levels throughout the treatment period; however, progesterone production in animals treated with hCG late in the luteal phase (days 10-16) steadily declined after the third treatment day. Expression of mRNA for P450SCC and 3 beta-HSD was markedly stimulated (P < 0.05) by hCG treatment early in the luteal phase. However, 3 beta-HSD message levels in corpora lutea from animals treated with hCG on days 10-16 were not different from those of day-16 control corpora lutea, whereas P450SCC mRNA was only minimally stimulated. There was a dramatic (P < 0.05) increase in mRNA levels for the aromatase enzyme and low density lipoprotein receptor in animals given hCG in both the early and the late luteal phase. In conclusion, there appears to be a differential responsiveness of the primate corpus luteum to hCG stimulation dependent upon luteal age. The loss in responsiveness to hCG in terms of maintenance of mRNA levels is reflective of the inability of the late luteal phase corpus luteum for continued progesterone biosynthesis in the face of heightened luteotropic stimulation.
A novel multibridge-channel MOSFET (MBCFET): fabrication technologies and characteristics (2003)

We have demonstrated a novel three-dimensional multibridge-channel metal-oxide-semiconductor field-effect transistor (MBCFET). This transistor was successfully fabricated using a conventional complementary metal-oxide-semiconductor process. We introduce the fabrication technologies and electrical characteristics of MBCFET in comparison with a conventional planar MOSFET. The MBCFET has more benefits than a conventional MOSFET. It shows 4.6 times larger current drivability than a planar MOSFET. This is due to the vertically stacked multibridge channels. The subthreshold swing of MBCFET is 61 mV/dec, which is almost an ideal value due to the thin body surrounded by gate. Based on a simulation result, we show that the MBCFET will have a large on-off state current ratio at short channel transistors.
Genetic algorithms: a survey (1994)

Genetic algorithms provide an alternative to traditional optimization techniques by using directed random searches to locate optimal solutions in complex landscapes. We introduce the art and science of genetic algorithms and survey current issues in GA theory and practice. We do not present a detailed study, instead, we offer a quick guide into the labyrinth of GA research. First, we draw the analogy between genetic algorithms and the search processes in nature. Then we describe the genetic algorithm that Holland introduced in 1975 and the workings of GAs. After a survey of techniques proposed as improvements to Holland's GA and of some radically different approaches, we survey the advances in GA theory related to modeling, dynamics, and deception.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
