Stent-supported Coil Embolization: The Treatment of Fusiform and Wide-neck Aneurysms and Pseudoaneurysms (2000)

OBJECTIVE We describe a consecutive series of patients treated with endovascular stent-supported coil embolization for symptomatic or enlarging wide-neck and fusiform aneurysms and pseudoaneurysms of the carotid and vertebrobasilar arteries. METHODS Seven stent-supported coil embolization procedures were performed for seven aneurysms in seven consecutive patients. There were five pseudoaneurysms, one dissecting aneurysm, and one berry aneurysm. Four aneurysms were located in the carotid artery, and three were located in the vertebrobasilar system. Three aneurysms were intracranial. Four patients were symptomatic, and three had angiographic evidence of increasing aneurysm size. RESULTS Technical success was achieved in six (86%) of seven patients. Entanglement of a coil with the stent struts necessitated partial coil delivery into the parent artery in one patient, but there were no neurological or other adverse sequelae. The 30-day rate of periprocedural stroke or mortality was 0%. At a mean clinical follow-up of 14.5 months, neurological status was at baseline or better in all patients. To date, all treated patients remain clinically asymptomatic with oral administration of aspirin only. CONCLUSION Stent-supported coil embolization represents an emerging therapeutic alternative to surgery for the treatment of symptomatic or enlarging wide-neck and fusiform aneurysms and pseudoaneurysms of the cervical and vertebrobasilar arteries, which are not amenable to conventional unsupported coil embolization. Experience with greater numbers of patients and long-term follow-up are required to further validate this technique.
Nanotubes and nanowires: the effect of impurities and defects on their electronic properties (2005)

In recent years, our laboratory has conducted extensive research studies on nanoscale systems. We give here a brief overview of these activities, and also present some previously unpublished results on the influence of impurities and defects on the electronic properties of carbon nanotubes and metallic nanowires. In the case of carbon nanotubes, we show that the presence of structural defects such as strong bends can lead to the presence of electronic states in the gap (for semiconducting nanotubes), which we correlate with recent scanning tunnel microscopy and spectroscopy measurements. In the case of metallic nanowires, we discuss the effect of the presence of carbon impurities, which have been suggested to be present in atomic gold nanowires, on their electronic transport properties. In particular, we show that the conductance in the presence of impurities deviates considerably from that of the pure gold atomic wires.
MOCVD and MOD of YBCO and Buffer Layers on Textured Metal Tapes (2009)

Different layer architectures produced by only MOD, only MOCVD and combinations of MOD buffers and MOCVD YBCO are presented. RTR MOCVD-YBCO layers obtained on MOD-CeO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> /MOD-LZO/Ni5 at%W tapes demonstrate critical current densities up to 2 MA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> at 77 K. On single LZO (50-100 nm) buffered Ni5 at%W tapes from Nexans Superconductors and on RTR MOCVD buffer layers critical current densities between 0.8 and 1.3 MA/cm are obtained. RTR MOD-LZO layers often show delamination during YBCO deposition. Preannealing treatment before YBCO deposition allows to avoid this. Tapes up to 10 m are produced by combination of MOD-LZO and RTR MOCVD-YBCO.
Importance of the aortic reservoir in determining the shape of the arterial pressure waveform – The forgotten lessons of Frank (2007)

It has been recognised for nearly 200 years that the human pressure waveform changes in shape with ageing and disease. The shape of the pressure waveform has been explained in terms of two fundamental models: the Windkessel (reservoir) and wave theory. In its simplest form the Windkessel model satisfactorily explains the pressure waveform in diastole but cannot model pressure changes in systole. Wave theory satisfactorily models the pressure waveform but predicts the existence of ‘self-cancelling’ forward and backward waves in diastole which are difficult to explain in biological terms. We propose that a hybrid reservoir–wave model better describes the pressure waveform and may enable assessment of aortic function from pressure measurements made at any large systemic artery.

High-fidelity light-shift gate for clock-state qubits (2021)

To date, the highest-fidelity quantum logic gates between two qubits have been achieved using the geometric-phase gate in trapped ions, with the two leading variants being the M\o{}lmer-S\o{}rensen gate and the light-shift (LS) gate. Both of these approaches have their respective advantages and challenges. For example, the latter is technically simpler and is natively insensitive to optical phases, but it has not been made to work directly on a clock-state qubit. We present a technique for implementing the LS gate that combines the best features of these two approaches: By using a small ($\ensuremath{\sim}\mathrm{MHz}$) detuning from a narrow (dipole-forbidden) optical transition, we are able to operate an LS gate directly on hyperfine clock states, achieving gate fidelities of $99.74(4)%$ using modest laser power at visible wavelengths. Current gate infidelities appear to be dominated by technical noise, and theoretical modeling suggests a path toward gate fidelity above $99.99%$.
Anticancer and Anti-Inflammatory Activities of Some New Pyrazolo[3,4-b]pyrazines (2018)

New derivatives of pyrazolo[3,4-<i>b</i>]pyrazines and related heterocycles were synthesized using 5-amino-3-methyl-4-nitroso-1-phenyl-pyrazole (<b>1</b>) as a starting material. The 5-acetyl derivative <b>15</b> was shown to be a useful key intermediate for the synthesis of several derivatives of pyrazolopyrazines. Some of the prepared compounds were evaluated for their anti-inflammatory and anti-breast cancer MCF-7 cell line activities. SAR study showed that compounds <b>15</b> and <b>29</b> exhibited remarkable anti-inflammatory activity, where <b>15</b> showed the same activity as that of the reference drug indomethacin. On the other hand, compounds <b>25i</b>, <b>25j</b> showed very significant inhibitory activity (<i>p</i> < 0.001) against MCF-7 breast cancer cell line.
Nucleotide sequence of rice (<i>Oryza sativa</i>L.) cDNA homologous to<i>cdc2</i>gene (1994)

We isolated and determined a nucleotide sequence of a rice DNA clone (SS224) denoted to rcdc2. This clone encodes an open reading frame of 302 amino acids and typical three conserved domains that exist in all cdc2 homologues. The evolutionary tree showed that rcdc2 was far from cdc2 and its homologous genes identified in various plants.
Chromosomes in Lung Cancer (1997)

Lung carcinomas are now the leading cause of neoplastic deaths among both men and women in the United States (1). With the increasing incidence of lung cancer, it is apparent that new diagnostic and staging techniques are needed. Because of the inadequacies of current therapeutic protocols, < 10% of all patients will achieve long-term survival and potential cures (2,3). Most therapeutic modalities currently available are specific to the histopathological type, i.e., small cell lung carcinoma (SCLC) versus nonsmall cell lung carcinoma (NSCLC). Our understanding of the biology of lung cancer indicates shared features among several histological variants (4). Identification of cytogenetic markers could allow for a better comprehension of this relationship that should, in turn, expand our knowledge of the overall disease process and offer the possibility of new treatment options. However, despite the high incidence of lung cancer, the cytogenetic data available are rather limited in this neoplasm compared to that for the hematological malignancies (5).
Invasiveness and ploidy of human mammary carcinomas in short-term culture. (1985)

Invasiveness and ploidy were examined in cultures of human epithelial cells derived from nonmalignant breast tissue, primary breast carcinomas, and breast cancer effusion metastases. Successful short-term culture was achieved from approximately 70% of the primary breast cancers. These primary cancers were essentially diploid by flow cytometry and karyotype in contrast to the effusion metastases, which were mostly aneuploid. The diploid tumor cells retained their malignant phenotype in culture as demonstrated by invasion into a denuded human amnion basement membrane. In contrast, epithelial cells cultured from nonmalignant mammary tissue did not invade the amnion. We suggest that the diploid carcinoma cultures may be useful for investigating the essential differences between normal and malignant cells and may complement information derived from studies of tumor cell lines with grossly aberrant karyotypes.
Morphology dependent UV photoresponse of Sn-doped ZnO microstructures (2017)

In this work, the UV sensing properties of Sn-doped and/or alloyed zinc oxide (ZnO) microstructures with different morphologies were investigated in order to elaborate the high performance UV photodetectors. We have compared two types of morphologies, i.e. Sn-doped ZnO films (ZnO:Sn) and ZnO microtetrapod (T) networks alloyed- and doped-with Sn (ZnO-T:Sn). The UV response (IUV/Idark) of ZnO:Sn is about 103 and 102 for 0.1 and 0.4 at% Sn, respectively. The three-dimensional highly porous ZnO-T:Sn networks demonstrated higher UV response (by two orders of magnitude) and much faster recovery for detection of UV light, which were attributed to the domination of fast processes such as modulation of potential barriers formed at the interface of the tetrapod arms, which are less dependent on adsorbed species. Thus, the UV response for devices with a distance between the pads (interelectrode distance) of about 60, 400, 800 and 1500 μm is 1.7 × 105, 2.4 × 104, 6.7 × 103 and 925, respectively. All samples demonstrated a sharp increase in photocurrent under illumination with UV light, as well as a fast recovery to the initial electrical baseline. Also, the influence of relative humidity on the rapidity of photodetectors based on ZnO:Sn films and ZnO-T:Sn networks was investigated, confirming a low impact on the rapidity of ZnO-T:Sn networks, with good repeatability and stable electrical baseline, which is very important for effective applications.
Push–pull (thio)barbituric acid derivatives in dye photosensitized radical and cationic polymerization reactions under 457/473 nm laser beams or blue LEDs (2013)

A series of new dyes based on (thio)barbituric acid derivatives were synthesized and used as photoinitiators of polymerization upon very soft irradiation (laser diodes at 457 nm and 473 nm; blue LED bulbs or even a halogen lamp). These dyes can work according to an oxidative cycle (dye/diphenyl iodonium salt/N-vinylcarbazole system) or a reductive cycle (dye/amine/alkyl halide system) and partly behave as organic photocatalysts. Ring-opening polymerization (ROP) of epoxides and radical polymerization (RP) of acrylates are easily promoted. Excellent RP and/or ROP polymerization profiles are obtained. The contrasting behavior of the thiobarbituric vs. barbituric acid derivative is discussed. The initiation mechanisms, analyzed by Electron Spin Resonance (ESR) and steady state photolysis experiments, are detailed.
Random matrix theory enabled performance analysis and algorithms for underwater signal processing (2015)

Random matrices arise naturally in many undersea signal processing applications such as sonar and underwater acoustic communications. For example, the matrix formed by stacking a noisy time series of observations collected at a sensor array alongside each other is a random matrix. Random matrix theory provides a mathematical framework for reasoning about and understanding the structure in such noisy matrix-valued signals in an analogous manner to how Fourier analysis provides us a mathematical framework for reasoning about and understanding the structure in noisy vector valued signals. We highlight some recent breakthroughs in random matrix theory that have allowed us to predict the fundamental performance limits of weak signal detection, estimation and classification and discuss some recent successes where the theory has led to the development of powerful new algorithms for better estimating weaker signals than previously thought possible.
&lt;title&gt;What Is A Picture Archiving And Communication System (PACS)?&lt;/title&gt; (1982)

A PACS is a digital system for acquiring, storing, moving and displaying picture or image information. It is an alternative to film jackets that has been made possible by recent breakthroughs in computer technology: telecommunications, local area nets and optical disks. The fundamental concept of the digital representation of image information is introduced. It is shown that freeing images from a material representation on film or paper leads to a dramatic increase in flexibility in our use of the images. The ultimate goal of a medical PACS system is a radiology department without film jackets. The inherent nature of digital images and the power of the computer allow instant free &quot;copies&quot; of images to be made and thrown away. These copies can be transmitted to distant sites in seconds, without the &quot;original&quot; ever leaving the archives of the radiology department. The result is a radiology department with much freer access to patient images and greater protection against lost or misplaced image information. Finally, images in digital form can be treated as data for the computer in image processing, which includes enhancement, reconstruction and even computer-aided analysis.
A new 1700 V IGBT module for 690 V AC industrial inverter applications (2000)

A new 1700 V IGBT is presented, with a PT structure formed by diffusing the collector and buffer layers into a homogeneous silicon wafer. This structure retains the superior Vce(sat)-switching loss trade-off of the PT IGBT, whilst achieving the greater short circuit ruggedness and easier parallel connection of NPT devices.

Lipid Biomarkers From Microbial Mats on the McMurdo Ice Shelf, Antarctica: Signatures for Life in the Cryosphere (2022)

Persistent cold temperatures, a paucity of nutrients, freeze-thaw cycles, and the strongly seasonal light regime make Antarctica one of Earth’s least hospitable surface environments for complex life. Cyanobacteria, however, are well-adapted to such conditions and are often the dominant primary producers in Antarctic inland water environments. In particular, the network of meltwater ponds on the ‘dirty ice’ of the McMurdo Ice Shelf is an ecosystem with extensive cyanobacteria-dominated microbial mat accumulations. This study investigated intact polar lipids (IPLs), heterocyte glycolipids (HGs), and bacteriohopanepolyols (BHPs) in combination with 16S and 18S rRNA gene diversity in microbial mats of twelve ponds in this unique polar ecosystem. To constrain the effects of nutrient availability, temperature and freeze-thaw cycles on the lipid membrane composition, lipids were compared to stromatolite-forming cyanobacterial mats from ice-covered lakes in the McMurdo Dry Valleys as well as from (sub)tropical regions and hot springs. The 16S rRNA gene compositions of the McMurdo Ice Shelf mats confirm the dominance of Cyanobacteria and Proteobacteria while the 18S rRNA gene composition indicates the presence of Ochrophyta, Chlorophyta, Ciliophora, and other microfauna. IPL analyses revealed a predominantly bacterial community in the meltwater ponds, with archaeal lipids being barely detectable. IPLs are dominated by glycolipids and phospholipids, followed by aminolipids. The high abundance of sugar-bound lipids accords with a predominance of cyanobacterial primary producers. The phosphate-limited samples from the (sub)tropical, hot spring, and Lake Vanda sites revealed a higher abundance of aminolipids compared to those of the nitrogen-limited meltwater ponds, affirming the direct affects that N and P availability have on IPL compositions. The high abundance of polyunsaturated IPLs in the Antarctic microbial mats suggests that these lipids provide an important mechanism to maintain membrane fluidity in cold environments. High abundances of HG keto-ols and HG keto-diols, produced by heterocytous cyanobacteria, further support these findings and reveal a unique distribution compared to those from warmer climates.
Logical Processing, Affect, and Delusional Thought in Schizophrenia (2000)

Deficits of logical reasoning have long been considered a hallmark of schizophrenia and delusional disorders. We provide a more precise characterization of "logic" and, by extension, of "deficits in logical reasoning." A model is offered to categorize different forms of logical deficits. This model acknowledges not only problems with making inferences, which is how logic deficits are usually conceived, but also problems in the acquisition and evaluation of premises (i.e., filtering of "input"). Early (1940-1969) and modern (1970-present) literature on logical reasoning and schizophrenia is evaluated within the context of the presented model. We argue that, despite a substantial history of interest in the topic, research to date has been inconclusive on the fundamental question of whether patients with delusional ideation show abnormalities in logical reasoning. This may be due to heterogeneous definitions of "logic," variability in the composition of patient samples, and floor effects among the healthy controls. In spite of these difficulties, the available evidence suggests that deficits in logical reasoning are more likely to occur due to faulty assessment of premises than to a defect in the structure of inferences. Such deficits seem to be provoked (in healthy individuals) or exacerbated (in patients with schizophrenia) by emotional content. The hypothesis is offered that delusional ideation is primarily affect-driven, and that a mechanism present in healthy individuals when they are emotionally challenged may be inappropriately activated in patients who are delusional.
A spectroscopic study of the fluorination and defluorination reactions on single-walled carbon nanotubes (2002)

The manipulation of isolated single-wall carbon nanotubes (SWNTs), rather than bundles, has led to active research in the field of the functionalisation of such carbon compounds. Different ways exist today to obtain some new soluble macromolecules from SWNTs. Here we focus on the fluorination functionalisation. As the solubility properties depend essentially on the degree of functionalisation, it is important to develop reliable and simple methods to quantify this. The CnF stoichiometry of three different fluorinated SWNTs samples are determined with X-ray photoelectron spectroscopy (XPS). Then the evolution of the Raman spectra with the degree of fluorination of these samples is discussed. An atomic force microscopy (AFM) study highlights the good solvation properties of the most fluorinated sample with a majority of isolated nanotubes being observed. Then we take advantage of these good solvation properties, combined with the possibility of recovering the pristine non-fluorinated nanotubes, to carry out surface enhanced Raman spectroscopy (SERS) studies of well-dispersed SWNTs. These studies put in evidence the bundle effect, which is due to the agglomeration of SWNTs into bundles. This effect can be readily observed by Raman spectroscopy.
Parents’ and Patients’ Perceptions of Postoperative Appearance in Adolescent Idiopathic Scoliosis (2006)

Radiographic and physical measures of deformity do not correlate well with patients' and parents' perceptions of appearance. Patients and parents do not strongly agree on the cosmetic outcome of AIS surgery. Therefore, given that the adolescents themselves undergo the surgery, patients' assessments of their deformity, rather than radiographic measures or parents' assessments, should play a major role in the evaluation of surgical success.

We have measured the complex ac resistivity $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\rho}}$ $(\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}{\ensuremath{\rho}}_{1}+i{\ensuremath{\rho}}_{2})$ of ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ thin films in the frequency range of 45 MHz to 50 GHz. The microwave conductivity ${\ensuremath{\sigma}}_{1}$, obtained from $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\rho}}$ in zero field, manifests considerable frequency dependence in the vicinity of ${T}_{c}$, showing that fluctuation and inhomogeneity effects are significantly reduced at high frequencies. With an applied dc magnetic field, the vortex dynamics changes at a crossover frequency ${f}_{x}$, showing scaling behavior ${\ensuremath{\rho}}_{i}\ensuremath{\propto}{\ensuremath{\omega}}^{{\ensuremath{\alpha}}_{i}}$ at low frequencies $(f&lt;{f}_{x})$ and mean-field behavior at high frequencies $\left(f&gt;{f}_{x}\right)$.

Optical Zeeman effect measurements on isolated and ferromagnetically coupled Nd<sup>3+</sup>ions in weakly doped YVO<sub>4</sub>crystals: evidence for lack of crystal field perturbations in ion pair interactions (2000)

Optical Zeeman effect measurements are performed at liquid helium temperature on Nd3+ ions in weakly doped YVO4 crystals in the range 11 350-11 390 cm-1 of the 4F3/2→ 4I9/2 neodymium transitions. This study provides confirmation that the concentration dependent satellite lines accompanying the optical transitions are due to ferromagnetically coupled pairs of Nd3+ ions in undistorted Y3+ sites of D2d point site symmetry. Nonlinear Zeeman splittings are observed in the range of experimental magnetic fields. These splittings are compared with those simulated from crystal field calculations by introducing the Zeeman Hamiltonian into the secular determinant before diagonalization. A reasonably good agreement between the calculated and experimental g-values is obtained, confirming that the exchange coupled neodymium pairs experience no crystal field perturbations.
