Pulsed Laser Deposition of C<sub>60</sub> Thin Films with Atomically Smooth Surface (1993)

Pulsed laser deposition was found to be a novel method for the fabrication of high-quality C 60 thin films with extremely smooth surfaces. The irradiation of a pulsed KrF excimer laser beam onto a C 60 powder target induced the formation of a plasma plume when the laser energy fluence was 40 mJ/cm 2 and higher. The ablated species were condensed onto a substrate in the form of thin film. Thin films deposited at laser energy fluences in the narrow range between 40 mJ/cm 2 and 50 mJ/cm 2 were confirmed to have a single phase of C 60 solid from the Raman scattering and optical absorption spectra as well as from the chromatography of benzene extract of the films. With increase of the laser energy fluence over 50 mJ/cm 2 , the deposited films included increasing amounts of photodecomposed components and, consequently, varying physical properties. Atomic force microscopy revealed atomically smooth surfaces of C 60 thin films laser-deposited at laser energy fluences between 40 mJ/cm 2 and 50 mJ/cm 2 .
Use of multi‐cell spheroids of ovarian carcinoma as an intraperitoneal radio‐immunotherapy model: Uptake, retention kinetics and dosimetric evaluation (1992)

The purpose of this study, using multi-cell spheroids as an in vitro model of micrometastases of ovarian carcinoma for i.p. radio-immunotherapy, was to measure the uptake and retention kinetics of 111In-labeled F(ab')2 fragments of OC125 monoclonal antibody (MAb) in spheroids of the NIH:OVCAR-3 cell line and to estimate absorbed doses with beta-emitting radionuclides (kinetics was assumed to be similar to that of indium-111). With 0.2-mm-diameter spheroids at different MAb concentrations the highest binding value was determined. Retention kinetics showed a biological half-life of 50 hr. These data were used to calculate absorbed doses by integration of Berger's latest-point kernels. Mean absorbed doses when spatial distribution was considered to be uniform at the surface (no penetration) or throughout the spheroid (total penetration) were, respectively, 247 and 417 Gy with 153Sm, and 90 and 135 Gy with 90Y. Thus, the use of a similar MAb concentration and specific activity in patients should lead to high absorbed doses in i.p. radio-immunotherapy of micrometastases.
Gain Enhancement in Reflected-Pump Erbium-Doped Fiber Amplifiers (1991)

Improved performance of EDFAs is achieved using wavelength-selective reflective filters to double-pass the pump beam. In low-gain amplifiers these filters can increase the saturation output power by 2 dB or reduce the pump power requirements.
Test generation for VLSI chips with embedded memories (1990)

An effective approach for generating patterns for testing memories embedded in logic is presented. Through circuit testability analysis, which is a study of the effect of process defects on memory circuits, unique algorithms can be derived for testing the memory. Circuit and logic designs for test features that are required to make the pattern generation process optimal are discussed. An analytical method is described which assesses the performance characteristics of the memory after functional test.
Growth of textured films of Bi2Sr2CaCu2O8+<i>x</i> from KCl solution (1989)

Films of Bi2Sr2CaCu2O8+x have been grown from KCl solution. Gadolinium gallium garnet substrates (1 1 1) oriented have been used. The films resulted highly textured with the c axis perpendicular to the substrate surface. The onset of the resistive transition was 85 K, while zero resistance was obtained at 50 K. This technique is particularly promising in view of the possibility to grow large epitaxial films of both the Bi2Sr2CaCu2O8+x and the Bi2Sr2Ca2Cu3O10+x phases.
Indirect alloreactivity and chronic rejection1 (2002)

This study demonstrates that a markedly reduced capacity for indirect alloreactivity does not affect the severity of intimal lesions in this model of CAV. The findings of this study question the role of indirect alloreactivity as the sole pathway of allorecognition leading to chronic rejection.
Trivalent Actinide and Lanthanide Complexation of 5,6-Dialkyl-2,6-bis(1,2,4-triazin-3-yl)pyridine (RBTP; R = H, Me, Et) Derivatives: A Combined Experimental and First-Principles Study (2012)

Complexations of lanthanide ions with 5,6-dialkyl-2,6-bis(1,2,4-triazin-3-yl)pyridine [RBTP; R = H (HBTP), methyl (MeBTP), ethyl (EtBTP)] derivatives have been studied in the acetonitrile medium by electrospray ionization mass spectrometry, time-resolved laser-induced fluorescence spectroscopy, and UV-vis spectrophotometric titration. These studies were carried out in the absence and presence of a nitrate ion in order to understand the effect of the nitrate ion on their complexation behavior, particularly in the poor solvating acetonitrile medium where strong nitrate complexation of hard lanthanide ions is expected. Consistent results from all three techniques undoubtedly show the formation of lower stoichiometric complexes in the presence of excess nitrate ion. This kind of nitrate ion effect on the speciation of Ln(3+) complexes of RBTP ligands has not so far been reported in the literature. Different Am(3+) and Ln(3+) complexes were observed with RBTP ligands in the presence of 0.01 M tetramethylammonium nitrate, and their stability constant values are determined using UV-vis spectrophotometric titrations. The formation of higher stoichiometric complexes and higher stability constants for Am(3+) compared to Ln(3+) ions indicates the selectivity of these classes of ligands. A single-crystal X-ray diffraction (XRD) study of europium(III) complexes shows the formation of a dimeric complex with HBTP and a monomeric complex with EtBTP, whereas MeBTP forms both the dimeric and monomeric complexes. Density functional theory calculations confirm the findings from single-crystal XRD and also predict the structures of Eu(3+) and Am(3+) complexes observed experimentally.

Herpes Simplex Virus and Risk of Cervical Cancer: A Longitudinal, Nested Case-Control Study in the Nordic Countries (2002)

Human papillomaviruses (HPVs) play the major role in cervical carcinogenesis. The authors reevaluated the role of herpes simplex virus type 2 (HSV-2) in this multistage process by conducting a longitudinal, nested case-control study using 1974-1993 data and comparing the results with those from a meta-analysis of studies. A Nordic cohort of 550,000 women was followed up for an average of 5 years, after which 178 cervical carcinoma cases and 527 controls were identified. HSV-2; HPV-16, HPV-18, and HPV-33; and Chlamydia trachomatis antibodies were determined at baseline by HSV-2 glycoprotein gG-2 and HPV virus-like-particle enzyme immunoassays and by using the microimmunofluorescence method. The relative risk of cervical carcinoma was calculated by conditional logistic regression. Longitudinal studies on HSV-2 and cervical neoplasia were identified through MEDLINE (National Library of Medicine, Bethesda, Maryland), and weighted mean relative risks were calculated. Smoking (relative risk = 1.6, 95% confidence interval (CI): 1.1, 2.3) and HPV-16/HPV-18/HPV-33 (relative risk = 2.9, 95% CI: 1.9, 4.3) were both associated with cervical carcinoma. The smoking- and HPV-16/HPV-18/HPV-33-adjusted relative risks for HSV-2 were 1.0 (95% CI: 0.6, 1.7) and 0.7 (95% CI: 0.3, 1.6), respectively, for HPV seropositives. In the meta-analysis, the relative risk for HSV-2 was 0.9 (95% CI: 0.6, 1.3). In both sets of data, HSV-2 did not play a role in cervical carcinogenesis.
Anisotropic velocity model building using OBS node tomography at Atlantis field, Gulf of Mexico (2010)

The accuracy of seismic depth images is strongly dependent on the accuracy of interval depth velocity models used for prestack depth migration. In this paper we present a tomography workflow designed to build the first anisotropic velocity model for Atlantis using OBS node data. The images obtained from prestack depth migration with this model show improvements over the previous isotropic image, especially at the reservoir level.
The mechanism of self-diffusion of ions in silicate systems (2006)

The special features of diffusion processes in noncrystalline models of SiO2, CaO · SiO2, and 2CaO · SiO2 with small admixtures of sodium oxide were studied by the method of molecular dynamics at 2000 and 3000 K. A purely ionic model with Born-Mayer potentials and parameters taken from the literature was used. In addition to the usual analysis of the mean-square displacements of particles, the maximum square displacements in each separate run 10000 time steps long were analyzed. Fairly long tunnels in the structure of silica were detected in the SiO2-Na2O system containing two sodium atoms only. Sodium ions can traverse these tunnels and execute a reciprocating motion in them at an approximately thermal velocity. The addition of calcium oxide gradually makes the silicate structure more compact, and long tunnels cease to exist in calcium meta-and orthosilicate models.
Knowledge-based Evaluation of Nursing Care Practice (2009)

Providing people with a complete and responsive healthcare solution requires a multi-tiered health service delivery system. One aspect in the healthcare hierarchy is the need for care provided by nurses. Nursing care and observation provide the basis for nurses to communicate their practice with others in the healthcare system. It is necessary to capture and manage knowledge of nursing care to improve the quality nursing practice. This paper proposes a novel knowledge-based decision support system for nurses to capture and manage nursing practice, and further, to monitor nursing care quality, as well as to test aspects of an electronic health record for recording and reporting nursing practice. As part of ongoing collaborative research of the nursing school and the department of computer science, a prototype toolset was developed to capture and manage nursing practice in order to improve the quality of care. A case study is presented to demonstrate the toolset used by nurses in a local hospital environment.
The role of the endogenous cannabinoid system in schizophrenia (2005)

Aims: Cannabis use is considered a risk factor for schizophrenia. However, the underlying neurobiological mechanisms remain conjectural. This study investigates the centrally acting endocannabinoid anandamide (AEA) in acute schizophrenia and the influence of cannabis use hereon. Methods: Concentrations of AEA were measured by HPLC/ MS in cerebrospinal fluid (CSF) and serum of acute antipsychotic-naïve schizophrenics (S-N; n=47), D2- (S- CT; n=37) and 5HT2A/D2-antagonistically (S-AT; n=34) treated acute schizophrenics, and healthy volunteers (HV; n=81). Psychopathology, patterns of cannabis use, and urine drug screenings were assessed independently. Results: AEA in CSF is significantly elevated in S-N. This is reversed in S-CT, but not in S-AT. Furthermore, CSF AEA is negatively correlated with psychotic symptoms in S-N. S-N with less than 5x of cannabis use lifetime and no acute use (n=25) show significantly higher AEA in CSF than HV (n=55; P=.000). They also differ significantly from patients with a history of more than 20x but no recent use of cannabis (n=9; P=.001). Conclusions: The elevation of AEA in schizophrenia may reflect a compensatory adaptation to dopaminergic hyperactivity. The history of cannabis use in S-N yields a significant association to AEA in CSF. The adaptive and counterbalancing role of AEA in S-N seems to be disrupted by the chronic use of cannabis.
A switching control strategy based on output regulation subspaces for the control of induction motors using a three-level inverter (2003)

In this work we present the design of a new switching control strategy for a three-level converter aimed to improve the performance of a direct torque control (DTC) for induction machines, special attention is given to the reduction of torque ripple. As in classical DTC, the proposed technique is aimed to directly regulate the outputs: torque and flux amplitude. We show that classical DTC can be considered as a particular case of the proposed control strategy. The proposed criterion to design the switching control sequence is based on a quadratic criterion of the output errors plus a prediction in one-step ahead, and an interesting partition of the input state space generated by the output regulation subspaces (ORS) to facilitate the selection of the control vector for reducing the computational load. As a result, a control vector is selected without the requirement of an auxiliary space vector or any other modulation technique. Simulations results using the proposed control technique confirm the validity of this approach.
Electroceutical Technology: Anti-Inflammatory Effects Of 40-160 T/S Inductively Coupled Electrical Stimulation (ICES) In The Acute Inflammation Model (2020)

Electromagnetic therapies (sic: electroceuticals) have been studied and used for many years as a treatment for many ailments including chronic and acute pain, inflammation, muscle atrophy, non-union bone fractures, as well as peripheral and central neuropathies [1]. Presently we seek to explore the realm of inductively coupled electrical stimulation (ICES) which is a subclass of pulsed electromagnetic field therapies (PEMFs) that uses rapidly changing electromagnetic fields to induce current flows in tissues. Such fields are hypothesized to act via various mechanisms. However, in the present we seek to clarify the often ambiguous and confusing literature regarding ICES mechanisms by conducting a scholarly review by which we then provide a dose reporting scheme for accurately describing the relevant parameters required to fully define ICES treatments. Based on our review and experience, we hypothesize that ICES requires very specific parameters to function appropriately. We seek to ascertain the efficacy of 40-160 Tesla/second (T/s) ICES stimulation as an anti-inflammatory therapy. A specific mechanism explored is the calcium/calmodulin (Ca/CaM) pathway implicated in the literature [2-9] . Our results bring into question the scientific methods of previously reported results by suggesting that nitric oxide levels in vitro fall below detection limits of commonly used methods for gauging Ca/CaM modulation by ICES. In an effort to elucidate the efficacy of ICES as an anti-inflammatory, we make use of the well-established carrageenan footpad edema (CFE) model in rats. The CFE model provides a spontaneously-resolving, acute inflammation model with a very well understood progression and biochemical mechanism. Our results indicate that 40-160 T/s ICES provides statistically significant, repeatable CFE reduction (P < 0.05) as measured by plethysmometry with no observed detrimental side-effects. Further work should focus on elucidating mechanism, evaluating safety, and exploring other potential applications—such as treating chronic conditions. The present studies support ICES as having the potential to provide life-changing therapy to individuals suffering from acute inflammation and pain. Given carefully conducted research in the future, we feel that ICES may revolutionize modern medicine not only from a treatment standpoint, but from the standpoint of understanding basic human electrophysiology and biochemistry.
Die Temperaturabhängigkeit des Isotopieeffektes bei Stromdurchgang in geschmolzenem Indiummetall (1956)

Bei verschiedenen Temperaturen wurde Gleichstrom durch Kapillaren mit geschmolzenem Indium geleitet, wobei 115 In an der Kathode und 113 In an der Anode angereichert wurde. Dieser sog. HAEFFNER-Effekt zeigte eine deutliche Temperaturabhängigkeit. Die Zunahme des Masseneffektes μ (10 -5 bei 210°; 6·10 -5 bei 820° C) mit der Temperatur war von der theoretisch vorhergesagten Größenordnung.
Production potential and economics of safed musli (<i>Chlorophytum borivilianum</i>) under intercropping system (2011)

A field experiment was conducted for two years, 2004–5 and 2005–6 during July–March at the research farm of the Central Institute of Medicinal and Aromatic Plants, Lucknow to study the compatibility, productivity and economics of intercropping in safed musli (Chlorophytum borivilianum Santapau & Fernandes). Vegetable crops viz cowpea, okra and bottle gourd, maize for grain, long duration pigeon pea, sweet basil in first year at their full and half population were intercropped with full population of safed musli in additive series. In the second year okra and sweet basil were replaced by lablab bean and sacred basil, respectively. Results of two years' experiments showed that intercropping of pigeon pea and bottle gourd with musli were advantageous in terms of overall yield, land equivalent ratio (LER), monetary advantage and economic return. The most appropriate combinations to realize the maximum advantage from intercropping were half plant population of bottle gourd grown at 100 × 100 cm or 120 × 90 cm spacing and pigeon pea grown at 120 × 20 cm spacing with musli. These combinations gave additional yield of 49.82 t ha−1of bottle gourd and 6.51 t ha−1 grain of pigeon pea (2-year mean) without significantly reducing the root yield of musli.
A fine scale phenotype–genotype virulence map of a bacterial pathogen (2012)

A large fraction of the genes from sequenced organisms are of unknown function. This limits biological insight, and for pathogenic microorganisms hampers the development of new approaches to battle infections. There is thus a great need for novel strategies that link genotypes to phenotypes for microorganisms. We describe a high-throughput strategy based on the method Tn-seq that can be applied to any genetically manipulatable microorganism. By screening 17 in vitro and two in vivo (carriage and infection) conditions for the pathogen Streptococcus pneumoniae, we create a resource consisting of >1800 interactions that is rich in new genotype-phenotype relationships. We describe genes that are involved in differential carbon source utilization in the host, as well as genes that are involved both in virulence and in resistance against specific in vitro stresses, thereby revealing selection pressures that the pathogen experiences in vivo. We reveal the secondary response to an antibiotic, including a dual role efflux pump also involved in resistance to pH stress. Through genetic-interaction mapping and gene-expression analysis we define the mechanism of attenuation and the regulatory relationship between a two-component system and a core biosynthetic pathway specific to microorganisms. Thus, we have generated a resource that provides detailed insight into the biology and virulence of S. pneumoniae and provided a road map for similar discovery in other microorganisms.

Herein, we fabricated the<italic>in situ</italic>polymerization of pyrrole (Py) on reduced graphene oxide (rGO), formulated as a nanocomposite support matrix for the deposition of nickel–nickel oxide (Ni–NiO) nanoparticles (NPs), as a cost-effective cathode catalyst for application in microbial fuel cells.
Blind restoration of single-channel image using iterative PCA (2013)

This paper proposes a single-channel image blind restoration by using iterative principal components analysis (PCA). Previously we proposed the iterative PCA approaches for blind restoration and proved its superiority over conventional methods. Still, there are some problems to be solved. One of them is precise and automatic way to determine the iteration number. This study tries to solve this by applying a blind image quality assessment for automatic optimization of the iterative number. For a verification example of atmospheric turbulence-degraded imagery our proposed method provides better improved restoration quality than conventional methods. In addition, experiments of simulations are conducted for real images. From the results, we can confirm that the proposed method gives higher PSNR as well as SSIM than the conventional methods even in real environments.
Review of the Use of the Glutamate Antagonist Riluzole in Psychiatric Disorders and a Description of Recent Use in Childhood Obsessive-Compulsive Disorder (2010)

The antiglutamatergic drug riluzole (Rilutek) is presently being used off label in the treatment of psychiatric conditions in adult patients and, increasingly, in children. This article briefly reviews the pharmacology of this drug and its current investigative and clinical uses and adverse effects. It also reports on our experience to date in the study of the drug in children, with emphasis on adverse effects noted so far in these younger patients.
Compression scheme for sparsely sampled light field data based on pseudo multi-view sequences (2018)

With the advent of light field acquisition technologies, the captured information of the scene is enriched by having both angular and spatial information. The captured information provides additional capabilities in the post processing stage, e.g. refocusing, 3D scene reconstruction, synthetic aperture etc. Light field capturing devices are classified in two categories. In the first category, a single plenoptic camera is used to capture a densely sampled light field, and in second category, multiple traditional cameras are used to capture a sparsely sampled light field. In both cases, the size of captured data increases with the additional angular information. The recent call for proposal related to compression of light field data by Joint Picture Expert Group (JPEG), also called JPEG Pleno, reflects the need of a new and efficient light field compression solution. In this paper, we propose a compression solution for sparsely sampled light field data. Each view of multi-camera system is interpreted as a frame of multi-view sequences. The pseudo multi-view sequences are compressed using state-ofart Multiview-extension of High Efficiency Video Coding (MV-HEVC). A subset of four light field images from Stanford dataset are compressed, on four bit-rates in order to cover the low to high bit-rates scenarios. The comparison is made with state-of-art reference encoder HEVC and its real-time implementation x265. The rate distortion analysis shows that the proposed compression scheme outperforms both reference schemes in all tested bit-rate scenarios for all the test images. The average BD-PSNR gain of 1.36 dB over HEVC and 2.15 dB over x265 is achieved using the proposed compression scheme.
