Risk factors for training-related injuries among men and women in basic combat training (2001)

Lower aerobic capacity and cigarette smoking were independently associated with a higher likelihood of injury in both men and women during a standardized program of physical training. Further studies are needed to assess associations between injury and body composition and muscular strength.
Transcutaneous electrical nerve stimulation (TENS) after open heart surgery. (1985)

Open heart surgery is associated with postoperative sternal pain, which is exacerbated by cough, deep breathing and movement, thus limiting the physical activity of the patient. Transcutaneous electrical nerve stimulation (TENS) was administered to 40 patients suffering from persistent chest pain immediately following open heart surgery, and to ten other patients complaining of pain between three and eight weeks after operation. The efficacy of TENS was assessed by the subjective recordings, analgesic drug requirement, capability to carry out deep inspirations with an "Incentive Deep Breathing Exerciser" apparatus, and repeated chest X-ray examinations. We conclude that TENS is a useful method of pain control and should be used more frequently in patients after open heart surgery, especially in the older patient and in patients with chronic lung disease.
Pulmonary Artery Catheterization: The Right Heart Should not be Left Out—A Case Report (1992)

Tricuspid valve stenosis in the setting of endocarditis is associated with a high morbidity. Diagnostic approaches incorporate a high clinical index of suspicion, echocardiographic evidence, and inferences about hemodynamic data derived from pulmonary artery catheterization. As demonstrated by the case presented herein, inadequate initial evaluation of right-sided pressures delayed the diagnosis and treatment of prosthetic tricuspid valve stenosis.

Convex optimization for precoder design in MIMO interference networks (2012)

Optimal precoder design for weighted sum-rate maximization in multiple-input multiple-output interference networks is studied. For this well known non-convex optimization problem, convex approximations based on interference alignment are developed, for both single-beam and multi-beam cases. Precoder design methods that consist of two phases, an interference alignment phase and a post-alignment optimization phase, are proposed. The interference alignment solution is taken as the input to the post-alignment optimization phase. For post-alignment weighted sum-rate maximization, novel iterative distributed algorithms are proposed based on the developed convex approximations. Simulation results show that the proposed algorithms achieve promising weighted sum-rate gains over existing interference alignment algorithms. Interestingly, for the multi-beam case, significant gain is achieved at all SNRs, including the high SNR regime.
Second harmonic microscopy to quantify renal interstitial fibrosis and arterial remodeling (2008)

Interstitial fibrosis is a powerful pejorative predictor of progression of nephropathies in a variety of chronic renal diseases. It is characterized by the depletion of kidney cells and their replacement by extracellular matrix, in particular, type-I fibrillar collagen, a protein scarce in normal interstitium. However, assessment of fibrosis remains a challenge in research and clinical pathology. We develop a novel methodology based on second harmonic generation (SHG) microscopy, and we image collagen fibers in human and mouse unstained kidneys. We take into account the variability in renal shape, and we develop automated image processing for quantitative scoring of thick murine tissues. This approach allows quantitative 3-D imaging of interstitial fibrosis and arterial remodeling with high accuracy. Moreover, SHG microscopy helps to raise pathophysiological questions. First, imaging of a large volume within a mouse kidney shows that progression of fibrosis is a heterogeneous process throughout the different renal compartments. Second, SHG from fibrillar collagens does not overlap with the glomerular tuft, despite patent clinical and experimental glomerulosclerosis. Since glomerulosclerosis involves SHG-silent nonfibrillar collagens, our work supports pathophysiological differences between interstitial fibrosis and glomerulosclerosis, a clearly nonfibrotic process.
Improving corrosion inhibition potentials using two triazole derivatives for mild steel in acidic medium: Experimental and theoretical studies (2019)

Electrochemical measurements as well as the weight loss method were investigated to determine the mechanism and performance of inhibition of (Z) -4 - ((2-bromobenzylidene) amino) -5-methyl-2-4-dihydro -3H-1,2,4-triazole-3-thione (2i) and (Z) -4 - ((3-bromobenzylidene) amino) -5-methyl-2-4-dihydro-3H-1,2,4 -triazole-3-thione (21) for the corrosion of mild steel in 1.0 M HCl. the outcomes show that the two triazole derivatives act as good inhibitors, and the efficiency of the inhibition follows the order (2i)>(21). Both derivatives are mixed inhibitors and adsorb on the metal surface according to the Langmuir model. An optical microscopy study points out an improved morphology of the surface of mild steel in the presence of the inhibitor studied. The inhibition mechanism was explored by the potential of the zero charge (Epzc) at the solution / metal interface. Dynamic simulation indicates the possibility of progressive substitution of water molecules on the surface of the iron surface. Thermodynamic and kinetic parameters were calculated and discussed. The quantum chemical parameters are calculated using the GAUSSIAN09W suite a good correlation between theoretical and experimental results has been shown.
Cerebral revascularization: extracranial-intracranial bypass. (2011)

Extracranial-intracranial (EC-IC) bypass remains an important revascularization technique for management of complex cerebrovascular disease. Despite evolving endovascular techniques, the role of bypass for the purpose of flow replacement prior to planned vessel sacrifice remains relevant for treatment of complex and fusiform aneurysms. The role of bypass for purposes of flow augmentation in the setting of cerebral ischemia is limited based on current data, but remains an important option for selected cases of athero-occlusive disease, in addition to a primary treatment for symptomatic moyamoya disease. An objective flow-based approach to EC-IC bypass can enhance decision-making in preoperative patient selection, intraoperative graft assessment, and postoperative follow-up.
Design optimization of transmitting antennas for weakly coupled magnetic induction communication systems (2017)

This work focuses on the design of transmitting coils in weakly coupled magnetic induction communication systems. We propose several optimization methods that reduce the active, reactive and apparent power consumption of the coil. These problems are formulated as minimization problems, in which the power consumed by the transmitting coil is minimized, under the constraint of providing a required magnetic field at the receiver location. We develop efficient numeric and analytic methods to solve the resulting problems, which are of high dimension, and in certain cases non-convex. For the objective of minimal reactive power an analytic solution for the optimal current distribution in flat disc transmitting coils is provided. This problem is extended to general three-dimensional coils, for which we develop an expression for the optimal current distribution. Considering the objective of minimal apparent power, a method is developed to reduce the computational complexity of the problem by transforming it to an equivalent problem of lower dimension, allowing a quick and accurate numeric solution. These results are verified experimentally by testing a number of coil geometries. The results obtained allow reduced power consumption and increased performances in magnetic induction communication systems. Specifically, for wideband systems, an optimal design of the transmitter coil reduces the peak instantaneous power provided by the transmitter circuitry, and thus reduces its size, complexity and cost.
Enantioselective Palladium‐Catalyzed Carbonylative Carbocyclization of Enallenes via Cross‐Dehydrogenative Coupling with Terminal Alkynes: Efficient Construction of α‐Chirality of Ketones (2017)

Abstract An enantioselective Pd II /Brønsted acid‐catalyzed carbonylative carbocyclization of enallenes ending with a cross‐dehydrogenative coupling (CDC) with a terminal alkyne was developed. VAPOL phosphoric acid was found as the best co‐catalyst among the examined 28 chiral acids, for inducing the enantioselectivity of α‐chiral ketones. As a result, a number of chiral cyclopentenones were easily synthesized in good to excellent enantiomeric ratio with good yields.
Study of mesoporous CdS-quantum-dot-sensitized TiO<sub>2</sub> films by using X-ray photoelectron spectroscopy and AFM (2014)

CdS quantum dots were grown on mesoporous TiO2 films by successive ionic layer adsorption and reaction processes in order to obtain CdS particles of various sizes. AFM analysis shows that the growth of the CdS particles is a two-step process. The first step is the formation of new crystallites at each deposition cycle. In the next step the pre-deposited crystallites grow to form larger aggregates. Special attention is paid to the estimation of the CdS particle size by X-ray photoelectron spectroscopy (XPS). Among the classical methods of characterization the XPS model is described in detail. In order to make an attempt to validate the XPS model, the results are compared to those obtained from AFM analysis and to the evolution of the band gap energy of the CdS nanoparticles as obtained by UV-vis spectroscopy. The results showed that XPS technique is a powerful tool in the estimation of the CdS particle size. In conjunction with these results, a very good correlation has been found between the number of deposition cycles and the particle size.
Amorphous diamondlike carbon films-a hard optical material for silicon solar cells (2002)

Amorphous diamondlike carbon (a:DLC) films are suitable materials to be used as a protective layer and antireflecting coating for silicon solar cells. Microhardness tests show high hardness of about 4700 kg/mm/sup 2/. Optical measurements, in the visible light, on silicon solar cells without an antireflecting (AR) coating on which a:DLC was deposited show a significant reduction in reflection of light of about 25/spl sim/45% as compared to the reflection from the solar cell before deposition of the a:DLC film. The I-V characteristics of solar cells without antireflecting coatings and with a:DLC as an AR coating layer show an improvement in short circuit current (from 107 mA to 116 mA) and in efficiency of the cell by 1% (from 8% to 9%).
Effects of Abamectin and Milbemycin D on Gypsy Moth (Lepidoptera: Lymantriidae) (1989)

Effects of abamectin and milbemycin D on gypsy moth, Lymantria dispar L., were determined. Fifty percent of third instars exposed for 2 h to 5.2 ppm milbemycin D on artificial diet were flaccid and paralyzed, whereas larvae exposed to 5.0 ppm abamectin were unaffected. When larvae were exposed to abamectin on artificial diet for 24 or 48 h, 50% of third instars died. Larvae exposed for 24 h to milbemycin D were not affected, but at 48 h 165 ppm caused 50% mortality of third instars. When larvae were exposed to milbemycin D residues for 48 h and observed 5·d later, the LC50was 92 ppm. LC50’s(ppm) when larvae were exposed for 72 h to residues on poplar foliage were 4 for abamectin, 1,454 for milbemycin D, and 125 for carbaryl. Five days after exposure to foliage residues, LC50’s (ppm) were 1 for abamectin, 244 for milbemycin D and 106 for carbaryl. On both substrates, abamectin was most toxic to third instars. Larvae exposed for 2 h to milbemycin D residues were flaccid and paralyzed but the effect was reversible.
State of the art of handwritten numeral recognition in Japan-The results of the first IPTP character recognition competition (2002)

The institute for Posts and Telecommunications Policy (IPTP) held its first character recognition competition in 1992 to ascertain the present status on ongoing research in character recognition and to find promising algorithms for handwritten numerals. The authors report the results of this competition and attempt to analyze substituted or rejected patterns in an effort to demonstrate the limitations of the present recognition technology and to clarify the remaining problems. They ascertain that by combining the complementary characteristics of each into a recognition system, the recognition ability is assumed to be remarkedly improved. Furthermore, they discuss a variety of combination rules for the multiexpert system and present promising results.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Water-Related Nosocomial Pneumonia Caused by Legionella pneumophila Serogroups 1 and 10 (1985)

Between August 1978 and November 1983, 21 cases of pneumonia caused by Legionella pneumophila occurred in the Leiden University Hospital, mainly among immunocompromised patients. A new serogroup of L. pneumophila, designated serogroup 10 (prototype strain Leiden 1), was isolated from bronchial secretions of four patients, and five patients had serological evidence of infection with this organism. Nine patients had a culture-confirmed infection with L. pneumophila serogroup 1. L. pneumophila serogroups 1 and 10 were also isolated from the hot potable water supply in the building to which 19 of the 21 patients had been admitted. The isolates of L. pneumophila serogroup 1 from patients and the hot potable water were identical in studies with monoclonal antibodies and had the same plasmid profiles. These findings provide further evidence that in our hospital potable water contaminated with L. pneumophila is a source of infection, mainly in immunocompromised patients.
Navier-Stokes calculations of transonic flows past open and transitional cavities (1988)

Computational simulations of deep and transitional cavities at transonic regimes were performed. The three-dimensional unsteady separation on the cavity floor was analyzed, and computational flow visualization inside the cavity was done. A parametric study was performed to investigate the effects of varying Mach number and the ratio delta/D, where delta is the instantaneous boundary layer thickness at the upstream lip and D is the depth. Both time-averaged and instantaneous solutions were obtained. Comparison of the solutions with experimental data were generally favorable; some discrepancies are explained.

Total Synthesis of (+)-Amphidinolide A. Structure Elucidation and Completion of the Synthesis (2005)

The structure elucidation of (+)-amphidinolide A, a cytotoxic macrolide, has been accomplished by employing a combination of NMR chemical shift analysis and total synthesis. The 20-membered ring of amphidinolide A was formed by a ruthenium-catalyzed alkene-alkyne coupling to forge the C15-C16 bond. Using the reported structure 1 as a starting point, a number of diastereomers of amphidinolide A were prepared. Deviations of the chemical shift of key protons in each isomer relative to the natural material were used as a guide to determine the locations of the errors in the relative stereochemistry. The spectroscopic data for the synthetic and natural material are in excellent agreement.
Gentamicin and Ampicillin in Human Bile (1971)

Concentrations of antibiotic in bile were measured following the administration of intramuscular gentamicin to five patients and intravenous ampicillin to one. Biliary gentamicin excretion by four individuals with abnormal hepatic function was minimal. Gentamicin levels in the bile of one patient with essentially normal hepatic function were 33% and 88% of those in serum. Intravenous ampicillin yielded high peak values in the bile and serum of one person with deranged hepatic function.
Application of Near-Infrared Spectroscopy in the Pharmaceutical Solid Dosage Form (1999)

Near-infrared (NIR) spectroscopy, one of the most rapidly growing methodologies in pharmaceutical analysis, has been used to analyze the pharmaceutical solid dosage form. The objective of this study was to examine the information that can be gathered from NIR spectroscopy and demonstrate the potential utility of the technique as an alternative to current methods of tablet performance testing. The tablet formulation included active drug (acetaminophen or theophylline), binder (hydroxyethylcellulose), filler (lactose, calcium sulfate, dibasic calcium phosphate dihydrate, or microcrystalline cellulose), and lubricant (magnesium stearate). The compression forces were varied from 5 to 25 kN. A Foss/NIRSystems scanning near-infrared spectrometer was used to measure the diffuse reflectance from the tablet surface. Each tablet was scanned on opposite sides to reduce the effects of positioning. First derivative and multiplicative scatter correction data treatments were explored. A calibration for compression force, independent of the filler, was developed. In addition, the spectra were able to distinguish among the fillers used. A comparison of these spectra with data collected earlier suggests that the technique could differentiate among drugs as well. Near-infrared diffuse reflection spectroscopy, when properly calibrated, can determine the compression force used to prepare a tablet. This measurement may be independent of the different active drugs or fillers used in the tablet formulations.
Vøring Plateau Continental Margin: Seismic Interpretation, Stratigraphy, and Vertical Movements (1989)

Seismic mapping tied to drilling data has provided a depositional, structural, and volcanic framework that describes the Wring Plateau continental margin since Late Jurassic time. The Vdring Basin was structured by Late Jurassic-Early Cretaceous extension and subsequent subsidence in the Cretaceous. It is divided into two basin provinces by the Molde-Bodd high. The opening of the Norwegian-Greenland Sea during the early Tertiary was preceded by uplift of the outer Wring Basin accompanied by extensional listric faulting in the Cretaceous sediments and intrusive activity. The early Tertiary extension was restricted to the outer Wring Basin, subsequently forming the Tertiary marginal basin. The igne ous activity is also restricted to this basin, gradually approaching the Wring Plateau Escarpment toward the time of breakup. Initial subaerial sea-floor spreading created the upper volcanic series at ODP Site 642, parts of the flow-sill complex landward of the escarpment and also caused deposition of ashes and tuffs in the Wring Basin. The post-open ing margin history is characterized by the progressive submergence of the Wring Plateau marginal high which for long periods was elevated with respect to the Wring Basin. The southern marginal high became fully sediment covered dur ing the early Miocene, whereas the northern part was not covered before the Pliocene. The basal sediments are of terrig enous origin, partly derived from erosion of the exposed lavas. Off the summit, a change to hemipelagic and pelagic compositions took place during the middle and late Eocene. The overall sediment record at the high is characterized by local erosion, redeposition, and instabilities. We propose that early Tertiary strike-slip motion, which triggered mass movements lasting into the early Miocene, is responsible for the spectacular north-south domes in the Wring Basin. Fi nally, a renewed major pulse of sedimentation and subsidence centered on the shelf edge commenced in latest Miocene time.

Evidence of genotypic resistance diversity of archived and circulating viral strains in blood and semen of pre-treated HIV-infected men (2004)

HIV resistant strains are frequent (70%) in the semen of heavily pre-treated men, and the diversity of genotypic resistance pattern confirms HIV compartmentalization. Thus, the risk of sexual transmission of resistant strains can only be partly predicted by standard tests applied to BP.
