Electrochemical growth of ZnO nano-rods on polycrystalline Zn foil (2003)

ZnO nano-rods were grown on polycrystalline Zn foil by cathodic electrodeposition in an aqueous zinc chloride/calcium chloride solution at 80°C. Variations in the solution concentration and substrate surface preparation were explored to shed light on the nucleation of the nano-rods. It was found that the nano-rod diameter increased with increasing solution concentration. Rolling striations and native ZnO on the surface of the Zn appeared to enhance nucleation and allowed more highly aligned, dense structures to be grown. By using low solution concentrations (5.0 × 10−4 M ZnCl 2) and non-electropolished Zn substrates, well faceted, hexagonal nano-rod structures of dimension ∼80 nm diameter and >1 µm length were obtained. X-ray studies showed the samples to be highly aligned but containing a Zn-oxychloride impurity phase. Annealing caused the impurity phase to disappear and resulted in the films having a sharp photoluminescence double peak at 380/396 nm.

Very high efficiency GaInAsP/GaAs strained-layer quantum well lasers (λ=980 nm) with GaInAsP optical confinement layers (1992)

A large increase in differential quantum efficiency from 35% to ≳45% per facet is obtained using a GaInAsP alloy (Eg≊1.65 eV), instead of GaAs, for the optical confinement layers in GaInAsP/GaAs strained-layer single quantum well separate confinement heterostructure diode lasers (λ=980 nm). The maximum value measured corresponds to a double-ended differential quantum efficiency of 93.4% and a slope efficiency of 1.18 mW/mA. The effective internal cavity loss in these structures is only ∼1 cm−1.
Metric and kernel learning using a linear transformation (2012)

Metric and kernel learning arise in several machine learning applications. However, most existing metric learning algorithms are limited to learning metrics over low-dimensional data, while existing kernel learning algorithms are often limited to the transductive setting and do not generalize to new data points. In this paper, we study the connections between metric learning and kernel learning that arise when studying metric learning as a linear transformation learning problem. In particular, we propose a general optimization framework for learning metrics via linear transformations, and analyze in detail a special case of our framework-that of minimizing the LogDet divergence subject to linear constraints. We then propose a general regularized framework for learning a kernel matrix, and show it to be equivalent to our metric learning framework. Our theoretical connections between metric and kernel learning have two main consequences: 1) the learned kernel matrix parameterizes a linear transformation kernel function and can be applied inductively to new data points, 2) our result yields a constructive method for kernelizing most existing Mahalanobis metric learning formulations. We demonstrate our learning approach by applying it to large-scale real world problems in computer vision, text mining and semi-supervised kernel dimensionality reduction.
Performance Analysis of Coherent 222-Gb/s NRZ PM-16QAM WDM Systems Over Long-Haul Links (2010)

We studied by simulation the nonlinear propagation of 222-Gb/s (27.75 GBaud) wavelength-division-multiplexing coherent nonreturn-to-zero polarization-multiplexed 16 quadrature amplitude modulation systems over long-haul links, considering both standard single-mode fiber (SSMF) and nonzero dispersion-shifted fiber. Many different dispersion maps, including precompensation, were explored to try and mitigate the impact of propagation impairments. Full electronic dispersion compensation without in-line dispersion-compensating units (DCUs) granted best performance with a system reach on SSMF fiber of ten spans with a span loss 23 dB. The presence of DCUs, as in lines designed for legacy 10-Gb/s intensity-modulated direct-detection systems, enhances nonlinear propagation penalties and the use of precompensation does not grant a significant advantage. A practical reach of 500-800 km can be estimated, when system margins are factored in .
Identification and characterization of the nano‐sized vesicles released by muscle cells (2013)

Several cell types secrete small membranous vesicles that contain cell-specific collections of proteins, lipids, and genetic material. The function of these vesicles is to allow cell-to-cell signaling and the horizontal transfer of their cargo molecules. Here, we demonstrate that muscle cells secrete nano-sized vesicles and that their release increases during muscle differentiation. Analysis of these nanovesicles allowed us to characterize them as exosome-like particles and to define the potential role of the multifunctional protein Alix in their biogenesis.
Heparin release from slippery‐when‐wet guide wires for intravascular use (2002)

Thin metallic wires with an adherent hydrophilic/ lubricious polymeric coating were manufactured in a new extrusion-like procedure. This procedure is part of a novel and efficient way of assembling lubricious guide wires for intravascular interventions, such as percutaneous transluminal angioplasty. It is reported that heparin can readily be incorporated in the hydrophilic coating. A set of heparin-containing guidewire models was made and studied in detail. This showed that (i). immersion of the guide-wire models in an aqueous environment leads to release of heparin from their surface; (ii). the presence of heparin in the coating does not impede the lubricity of the coils; (iii). addition of stearic acid in the coating, next to heparin, does not influence the lubricity of the guide-wire models. Two different charges of heparin (designated heparin-low and heparin-high) were incorporated in the coating. It is discussed that release of heparin from the surface of medical devices (e.g. guide wires and catheters) is much more effective than systemic heparinization, basically because dissolved heparin molecules have a much larger probability of simply passing a medical device's surface (axial convection) rather than contacting it (radial diffusion).

Hydraulic Testing of Intravascular Axial Flow Blood Pump Designs With a Protective Cage of Filaments for Mechanical Cavopulmonary Assist (2010)

To provide hemodynamic support to patients with a failing single ventricle, we are developing a percutaneously inserted, magnetically levitated axial flow blood pump designed to augment pressure in the cavopulmonary circulation. The device is designed to serve as a bridge-to-transplant, bridge-to-recovery, bridge-to-hemodynamic stability, or bridge-to-surgical reconstruction. This study evaluated the hydraulic performance of three blood pump prototypes (a four-bladed impeller, a three-bladed impeller, and a three-bladed impeller with a four-bladed diffuser) whose designs evolved from previous design optimization phases. Each prototype included the same geometric protective cage of filaments, which stabilize the rotor within the housing and protect the housing wall from the rotating blades. All prototypes delivered pressure rises over a range of flow rates and rotational speeds that would be sufficient to augment hemodynamic conditions in the cavopulmonary circulation. The four-bladed impeller outperformed the two remaining prototypes by >40%; this design was able to generate a pressure rise of 4-28 mm Hg for flow rates of 0.5-10 L/min at rotational speeds of 4,000-7,000 RPM. Successful development of this blood pump will provide clinicians with a feasible therapeutic option for mechanically supporting the failing Fontan.
Revisiting the Scarface Legacy: The Victim/Offender Relationship and Mariel Homicides in Miami (2001)

By incorporating the direct impact of ethnicity and immigration on crime, this article isthe first to use multivariate methods to compare and contrast Mariel to Afro-Caribbean, African American, and non-Mariel Latino homicides in a predominately immigrant city. In the current study, Mariels were overinvolved in acquaintance homicides, but little evidence surfaced that they were disproportionately involved in stranger homicides or were unusually violent, both dominant themes in popular stereotypes. In fact, an analysis of homicide event narratives verified the mundane nature of Mariel homicides, implying that the legacy of Scarface is not the Mariel killer but the Mariel Myth.
Seven Years of Experience With C2 Translaminar Screw Fixation: Clinical Series and Review of the Literature (2011)

This study reports 103 C2 translaminar screws, the largest single-surgeon series to date. C2 translaminar screws are a technically feasible, low-risk option for C2 fixation, with a 97.6% fusion rate in this series.
Dispersion control and slow light in slotted photonic crystal waveguides (2008)

Slotted photonic crystal waveguides combine the ability to confine light in air with the dispersion control available from photonic crystals. Here, we study the dependence of their dispersion properties on geometry, especially the slot width, and demonstrate slow light operation with group indices in excess of 100.
A constrained matching pursuit approach to audio declipping (2011)

We present a novel sparse representation based approach for the restoration of clipped audio signals. In the proposed approach, the clipped signal is decomposed into overlapping frames and the declipping problem is formulated as an inverse problem, per audio frame. This problem is further solved by a constrained matching pursuit algorithm, that exploits the sign pattern of the clipped samples and their maximal absolute value. Performance evaluation with a collection of music and speech signals demonstrate superior results compared to existing algorithms, over a wide range of clipping levels.
Expression of CD66a in multiple myeloma (2002)

CD66a is a member of the carcinoembryonic antigen family and has been suggested to function as an intercellular adhesion molecule and cell growth regulator. Expression of CD66a in myeloma cells was examined with mAb TS135 against CD66a transfectants of murine-transformed fibroblasts. The reactivity of mAb TS135 with CD66a, CD66c, and CD66e was revealed. CD66a in myeloma cells was considered to be detectable with this mAb, since CD66c and CD66e are not expressed in them. CD66a was detected in three myeloma cell lines and an IgM-producing B-cell line. In clinical bone marrow specimens, including 18 multiple myeloma, two primary macroglobulinemia, and a case of CLL-like chronic lymphoproliferation with monoclonal IgG production, CD66a and three conventional myeloma cell markers (PCA-1, CD38, and CD56) were examined by indirect immunofluorescence assay. The results showed that 18 out of 21 cases (86%) were CD66a+, and PCA-1 showed the highest correlation with CD66a among conventional markers. Primary macroglobulinemia and chronic lymphoproliferation were also CD66a+. Two-dimensional flow cytometry with mAbs TS135 and CD38 confirmed the reactivity of TS135 with myeloma cells in those bone marrow specimens. The findings suggest that CD66a is expressed in multiple myeloma with high frequency.
Wwan/lte printed loop tablet computer antenna and its body sar analysis (2011)

Abstract A WWAN/LTE printed loop antenna for tablet computer application is presented.The printed loop antenna is a half‐wavelength loop strip coupled‐fed by a patch monopole, which performs not only as a coupling feed but also as an efficient radiator for the antenna. By embedding a printed distributed inductor in the loop strip, dual‐resonance excitation of the half‐wavelength mode of the coupled‐fed loop antenna is obtained, which forms the antenna's lower band at about 800 MHz to cover the LTE700/GSM850/900 operation (704–960 MHz). The antenna's upper band is formed by both the resonant modes contributed by the patch monopole and the higher order resonant modes contributed by the loop strip. The upper band shows a large bandwidth (>1 GHz) to cover the GSM1800/1900/UMTS/LTE2300/2500 operation (1710–2690 MHz). Further, with a planar and compact structure (12 × 75 mm 2 ), the antenna is suitable to be disposed in the limited space inside the tablet computer and meets the body specific absorption rate (SAR) requirement (<1.6 W/kg for 1‐g body tissue) for practical applications. Details of the proposed antenna and its body SAR results are presented. © 2011 Wiley Periodicals, Inc.

Interleukin‐2 Up‐Regulates Expression of the Human Immunodeficiency Virus Fusion Coreceptor CCR5 by CD4<sup>+</sup>Lymphocytes In Vivo (2000)

Intermittent interleukin-2 (IL-2) therapy can substantially increase CD4+ T cell counts of human immunodeficiency virus (HIV)-infected subjects. Administration of IL-2 led to transient up-regulation of CCR5 on CD4+ T cells; up to 87% of CD4+ cells expressed CCR5 after a 5-day cycle, with return to baseline levels within 2 weeks. Unlike in vitro studies, CCR5 was coexpressed with CD45RA and CXCR4 on CD4+ T cells after IL-2 therapy. The observed increase in coreceptor expression was not associated with detectable increases in viral replication. IL-2 therapy induced CCR5 expression in >90% of circulating memory CD4+ T cells, determined to be a long-term reservoir of HIV, suggesting significant activation of these cells. These studies demonstrate that levels of expression of HIV coreceptors alone do not always correlate with HIV replication in vivo and that IL-2 therapy activates a majority of memory T cells in the circulation and likely throughout the immune system.
Valorization of agro-industrial wastes towards the production of rhamnolipids (2016)

In this work, oil mill wastewater (OMW), a residue generated during olive oil extraction, was evaluated as an inducer of rhamnolipid production. Using a medium containing as sole ingredients corn steep liquor (10%, v/v), sugarcane molasses (10%, w/v) and OMW (25%, v/v), Pseudomonas aeruginosa #112 produced 4.5 and 5.1g of rhamnolipid per liter in flasks and reactor, respectively, with critical micelle concentrations as low as 13mg/l. Furthermore, in the medium supplemented with OMW, a higher proportion of more hydrophobic rhamnolipid congeners was observed comparing with the same medium without OMW. OMW is a hazardous waste which disposal represents a serious environmental problem; therefore, its valorization as a substrate for the production of added-value compounds such as rhamnolipids is of great interest. This is the first report of rhamnolipid production using a mixture of these three agro-industrial by-products, which can be useful for the sustainable production of rhamnolipids.
Electronic structures and optical properties of TiO <sub>2</sub> : Improved density-functional-theory investigation (2012)

TiO2 has been recently used to realize high-temperature ferromagnetic semiconductors. In fact, it has been widely used for a long time as white pigment and sunscreen because of its whiteness, high refractive index, and excellent optical properties. However, its electronic structures and the related properties have not been satisfactorily understood. Here, we use Tran and Blaha's modified Becke-Johnson (TB-mBJ) exchange potential (plus a local density approximation correlation potential) within the density functional theory to investigate electronic structures and optical properties of rutile and anatase TiO2. Our comparative calculations show that the energy gaps obtained from mBJ method agree better with the experimental results than that obtained from local density approximation (LDA) and generalized gradient approximation (GGA), in contrast with substantially overestimated values from many-body perturbation (GW) calculations. As for optical dielectric functions (both real and imaginary parts), refractive index, and extinction coefficients as functions of photon energy, our mBJ calculated results are in excellent agreement with the experimental curves. Our further analysis reveals that these excellent improvements are achieved because mBJ potential describes accurately the energy levels of Ti 3d states. These results should be helpful to understand the high temperature ferromagnetism in doped TiO2. This approach can be used as a standard to understand electronic structures and the related properties of such materials as TiO2.
A genome-wide IR-induced RAD51 foci RNAi screen identifies CDC73 involved in chromatin remodeling for DNA repair (2015)

To identify new regulators of homologous recombination repair, we carried out a genome-wide short-interfering RNA screen combined with ionizing irradiation using RAD51 foci formation as readout. All candidates were confirmed by independent short-interfering RNAs and validated in secondary assays like recombination repair activity and RPA foci formation. Network analysis of the top modifiers identified gene clusters involved in recombination repair as well as components of the ribosome, the proteasome and the spliceosome, which are known to be required for effective DNA repair. We identified and characterized the RNA polymerase II-associated protein CDC73/Parafibromin as a new player in recombination repair and show that it is critical for genomic stability. CDC73 interacts with components of the SCF/Cullin and INO80/NuA4 chromatin-remodeling complexes to promote Histone ubiquitination. Our findings indicate that CDC73 is involved in local chromatin decondensation at sites of DNA damage to promote DNA repair. This function of CDC73 is related to but independent of its role in transcriptional elongation.
Plasma paracetamol concentration at hospital presentation has a dose-dependent relationship with liver injury despite prompt treatment with intravenous acetylcysteine (2016)

This study supports theoretical concerns that the current intravenous dose of NAC may be too low in the setting of higher paracetamol exposure.
Preparation and Properties of Carrageenan-g-Poly(Acrylic Acid)/Bentonite Superabsorbent Composite (2011)

A novel biopolymer-based superabsorbent hydrogel composite based on kappa-carrageenan (κC) have been prepared via graft copolymerization of acrylic acid (AA) in the presence of bentonite powder using methylenebisacrylamide (MBA) as a crosslinking agent and ammonium persulfate (APS) as an initiator. The hydrogel structure was confirmed using FTIR spectroscopy and the morphology of the samples was examined by scanning electron microscopy (SEM). The affecting variables onto graft polymerization (i.e. AA, MBA and APS concentration, as well as the bentonite amount) were systematically optimized to achieve a hydrogel with swelling capacity as high as possible. The results of Brunauer–Emmett–Teller (BET) analysis showed that the average pore diameter of the synthesized hydrogel was 11.5 nm. The effect of various salt media and solutions with different pHs on the swelling of the superabsorbent was also studied.
Exploitation Management of Underground Dams by Using Mathematical Models of Finite Difference in GMS7.1 (The Case Study of Sanganeh Underground Dam-Iran) (2012)

Being located in an arid and semi-arid climate, the scarcity of surface water, and the growing population have caused the use of underground dams for storing groundwater to flourish in Iran over the last 10 years. So that at the moment, several underground dams have been built in different areas in Iran. One of the most important issues about underground dams and any hydraulic structure in general that is built for storing water, is exploitation management. Thus in this research, by applying mathematical modeling process, first through basic studies, conceptual model of underground dams in GMS7.1 software was created by the help of vector and raster data produced by GIS software. In the next step, after determining model networks, boundary conditions, and the necessary data input such as hydrodynamic coefficients of underground dam reservoir and recharge and discharge rates, the model was applied by the use of Modflow module in GMS7.1 software. Then, considering the observed well and comparison of the conclusions from water level resulting from the model and observed figures, calibration step of the model was done. After preparing the calibrated model, the authenticity of the model’s data was assessed and after verifying the accuracy of the model’s results, through applying 4 scenarios, groundwater level changes in the underground dam reservoir was investigated for exploitation management. In the 1 to 3 scenarios by assuming the change in the recharge rate due to rainfall at the predicted time, the maximum operational rate, permitted from the existing operational well in the reservoir, was suggested. In the fourth scenario, the appropriate place for building other operational
Can pale, soft, exudative pork be prevented by postmortem sodium bicarbonate injection? (1998)

Previous attempts at eliminating the problem of PSE pork by genetic selection or rapid postmortem cooling have been only partially successful. A new approach, namely, postmortem injection of sodium bicarbonate (SBC), was tested on halothane-positive gilts. Sixteen pigs were used to establish a suitable SBC concentration. At approximately 15 min after death, the longissimus of one side of the carcass was injected with 10% (by weight) of .2 to .4 M SBC solutions containing .7% NaCl (wt/vol). All concentrations resulted in a higher ultimate pH, improved muscle color, and reduced drip loss. In a second experiment, with 23 pigs, .3 M SBC was injected into the longissimus and the biceps femoris at either 15 min or 24 h after death and with or without inclusion of .7% NaCl (wt/vol). Compared with controls, the 15-min SBC + NaCl injected samples had darker color (L* of 47 vs 53 in controls), higher ultimate pH (5.6 vs 5.3), lower drip loss (5% vs 10%), and increased protein solubility (140 vs 115 mg/g). Injection at 24 h reduced drip loss (from 10% to 5.7%) but did not correct the color defect. The SBC alone and SBC + NaCl treatments had essentially the same effects in reducing drip loss, increasing ultimate pH, and improving color; but the SBC-NaCl injected samples had improved juiciness and flavor compared with SBC. Early postmortem sodium bicarbonate injection seems to prevent the development of PSE pork when injected into carcasses of halothane-sensitive pigs.
A new sensorless control strategy used in direct-drive PMSG wind power system (2010)

This paper introduces the operating principle of back-to-back converter in direct-drive variable speed constant frequency (VSCF) wind power system. In system in order to obtain the accurate information of motor speed and angle, and alleviate the shortcomings, a new estimation method of permanent magnet synchronous generator (PMSG) speed and rotor position based on phase-locked loop (PLL) is proposed in this paper. Simulation model and experimental prototype were established. The simulation and experimental results indicate that the sensorless vector control method based on PLL can obtain accurate speed and angle information of PMSG. Then the fast response, good current control effect, and good steady state and dynamic performances, can also be achieved by sensorless vector control of PMSG. Specially, this method is suitable for medium and small scale wind power generation system.
