Enhancement of Backlight-Scaled Images (2013)

Switching the liquid crystal display (LCD) backlight of a portable multimedia device to a low power level saves energy but results in poor image quality especially for the low-luminance image areas. In this paper, we propose an image enhancement algorithm that overcomes such effects of dim LCD backlight by taking the human visual property into consideration. It boosts the luminance of image areas below the perceptual threshold while preserving the contrast of the other image areas. We apply the just noticeable difference theory and decompose an image into an HVS response layer and a background luminance layer. The boosting and compression processes, which enhance the visibility of the low-luminance image areas, are carried out in the background luminance layer to avoid luminance gradient reversal and over-compensation. The contrast of the processed image is further enhanced by exploiting the Craik-O'Brein-Cornsweet visual illusion. Experimental results are provided to show the performance of the proposed algorithm.

Fabrication of plastic biochips (2010)

A versatile surface functionalization procedure based on rf magnetron sputtering of silica was performed on poly(methylmethacrylate), polycarbonate, polypropylene, and cyclic olefin copolymers (Topas 6015). The hybrid thermoplastic surfaces were characterized by x-ray photoelectron spectrometer analysis and contact angle measurements. The authors then used these hybrid materials to perform a sandwich assay targeting an HIV-1 antibody using fluorescent detection and biotinylated peptides immobilized using the bioaffinity of biotin-neutravidin. They found a limit of detection similar to arrays on glass surfaces and believed that this plastic biochip platform may be used for the development of disposable immunosensing and diagnostic applications.
Radioactive Waste‐Portland Cement Systems: I, Radionuclide Distribution (1984)

Crystal chemical stabilization of radioactive wastes can be achieved during clinkering of, or with, ordinary portland cement. Waste loadings of 20 to 30 wt% are achieved by dilute solid solution of waste ions into cementitious host lattices. Higher waste loadings result in compatible noncementitious radiophases. The cementitious phases hydrate without loss of compressive strength. Crystallochemical relationships predict that the radionuclide partitioning in the anhydrous clinkered phases will be maintained in the hydration products. These cementitious hydroxylated radiophases would be in internal equilibrium under anticipated repository conditions. The radio‐nuclide distributions observed are described in the context of established phase equilibria for commercial waste‐cement systems, but are applicable to transuranic, medium‐, and low‐level wastes.
Sub-20 nm Si/Ge Superlattice Nanowires by Metal-Assisted Etching (2009)

An effective and low-cost method to fabricate hexagonally patterned, vertically aligned Si/Ge superlattice nanowires with diameters below 20 nm is presented. By combining the growth of Si/Ge superlattices by molecular beam epitaxy, prepatterning the substrate by anodic aluminum oxide masks, and finally metal-assisted chemical wet etching, this method generates highly ordered hexagonally patterned nanowires. This technique allows the fabrication of nanowires with a high area density of 10(10) wires/cm(2), including the control of their diameter and length.
An Improved Eliminating SQL Injection Attacks Based Regular Expressions Matching (2012)

Web applications have brought with them new classes of network security vulnerabilities, such as SQL Injection Attack. SQL Injection Attack is a class of attacks that many of the Web-based systems are highly vulnerable to, and there is no know fool-proof defense against such attacks. Static analysis is one of the techniques in defense of SQL Injection. In this paper, we propose an improved technique eliminates the need to modify source code of application scripts. The improved Eliminating SQL Injection Attacks technique bases the regular expressions instead of using SQL Graph representation using SQL-FSM in static analysis.
The endothelial barrier and cancer metastasis: Does the protective facet of platelet function matter? (2020)

Overwhelming evidence suggests that platelets have a detrimental role in promoting cancer spread via platelet-cancer cell interactions linked to thrombotic mechanisms. On the other hand, a beneficial role of platelets in the preservation of the endothelial barrier in inflammatory conditions has been recently described, a phenomenon that could also operate in cancer-related inflammation. It is tempting to speculate that some antiplatelet strategies to combat cancer metastasis may impair the endogenous platelet-dependent mechanisms preserving endothelial barrier function. If the protective function of platelets is impaired, it may lead to increased endothelial permeability and more efficient cancer cell intravasation in the primary tumor and cancer cell extravasation at metastatic sites. In this commentary, we discuss current evidence that could support this hypothesis.
A Multicenter, Double-Blind, Placebo-Controlled Trial of Autologous Fibroblast Therapy for the Treatment of Nasolabial Fold Wrinkles (2012)

Autologous fibroblast therapy is safe and effective for the treatment of NLF wrinkles. The availability of autologous cell therapy marks the beginning of a new phase in aesthetic therapy.
Simulation study on single event burnout in linear doping buffer layer engineered power VDMOSFET (2016)

The addition of a buffer layer can improve the device's secondary breakdown voltage, thus, improving the single event burnout (SEB) threshold voltage. In this paper, an N type linear doping buffer layer is proposed. According to quasi-stationary avalanche simulation and heavy ion beam simulation, the results show that an optimized linear doping buffer layer is critical. As SEB is induced by heavy ions impacting, the electric field of an optimized linear doping buffer device is much lower than that with an optimized constant doping buffer layer at a given buffer layer thickness and the same biasing voltages. Secondary breakdown voltage and the parasitic bipolar turn-on current are much higher than those with the optimized constant doping buffer layer. So the linear buffer layer is more advantageous to improving the device's SEB performance.
Location Area Design Algorithms for Minimizing Signalling Costs in Mobile Networks (2007)

In the next generation, IP-based mobile networks, one of the most important QoS parameters, are the delay and the delay variation. The cell handover causes incremental signalling traffic, which can be critical from the point of view of delay variation. It worsens the quality param-eters of the real-time services, which are the backbone of next generation mobile commercial services. We have designed and implemented two algorithms: a location area forming algo-rithm (LAFA) and a cell regrouping algorithm (CEREAL), which can help us to guarantee QoS parameters in the next generation mobile networks. We used our realistic mobile environment simulator to generate input statistics on cell changes and incoming calls for our algorithms and by comparing the values of the cost functions proposed by us, we recognized that significant reduction was achieved in the amount of the signalling traffic; the location update cost was decreased by 40-60% in average.
Cystathionine as a marker for 1p/19q codeleted gliomas by in vivo magnetic resonance spectroscopy (2019)

Our results provide strong evidence of a selective vulnerability of codeleted gliomas to serine and glutathione depletion and point to cystathionine as a possible noninvasive marker of treatment response.
Optimal vehicle dynamics control for combined longitudinal and lateral autonomous vehicle guidance (2013)

This contribution proposes a model-based predictive control approach for combined longitudinal and lateral vehicle guidance. The controller, which has been designed for an automotive collision avoidance system, aims at following a desired evasion trajectory at the handling limits. Thereby, the trajectory following problem is decomposed in a path following and a velocity trajectory tracking problem using the wheel steering angle and the longitudinal acceleration as control inputs. There are two major advantages of this approach. First, the a priori knowledge of the evasion trajectory is explicitly incorporated into the computation of control inputs. Second, the combined transmission of longitudinal and lateral tire forces is considered in the sense of an integrated vehicle dynamics control approach. Experimental results show the potential of the introduced control scheme.

Free-electron laser saturated regime, cavity modulation, and harmonic generation (1998)

We explore the analytical dependence of the free-electron laser (FEL) saturated power on the cavity detuning and discuss the dependence of the higher harmonics generated power on this quantity. We show that a suitable modulation of the cavity detuning may provide a pulsed behaviour of the laser, superimposed to the natural mode locking. The new temporal characteristics of the laser are discussed and it is shown that they can be controlled by controlling the cavity-length modulation period. We also study the effect of this modulation on the harmonic generation. The possibility of extending the same mechanism to a free electron laser operating with a storage ring is finally discussed and we show that, under certain conditions, it may modify the characteristics of the stationary configuration.
Techniques and tools for estimating ionospheric effects in interferometric and polarimetric SAR data (2011)

The InSAR Scientific Computing Environment (ISCE) is a flexible, extensible software tool designed for the end-to-end processing and analysis of synthetic aperture radar data. ISCE inherits the core of the ROIPAC interferometric tool, but contains improvements at all levels of the radar processing chain, including a modular and extensible architecture, new focusing approach, better geocoding of the data, handling of multi-polarization data, radiometric calibration, and estimation and correction of ionospheric effects. In this paper we describe the characteristics of ISCE with emphasis on the ionospheric modules. To detect ionospheric anomalies, ISCE implements the Faraday rotation method using quad-polarimetric images, and the split-spectrum technique using interferometric single-, dual- and quad-polarimetric images. The ability to generate co-registered time series of quad-polarimetric images makes ISCE also an ideal tool to be used for polarimetric-interferometric radar applications.
High temporal resolution retrospective motion correction with radial parallel imaging (2011)

A method for motion correction in multicoil imaging applications, involving both data collection and reconstruction, is presented. A bit-reversed radial acquisition scheme, in conjunction with a rapid self-calibrated parallel imaging method, Generalized auto-calibrating partial parallel acquisition (GRAPPA) operator for wider radial bands (GROWL), is used to achieve motion correction at a high temporal resolution. View-by-view in-plane motion correction is achieved in 2D imaging, while 3D motion correction is achieved for every two consecutive slice-encoding planes in 3D imaging. In the proposed technique, GROWL contributes in two aspects: First, a central k-space circle/cylinder used as the motion-free reference is generated from a small number of radial lines/planes; Second, undersampled k-space regions resulting from rotation and inconsistent (e.g. intraview and nonrigid body) motion can be filled in. When compared with navigator-based motion correction methods, the proposed method does not prolong scan time and can be applied to short-TR sequences. Magn Reson Med, 2011. © 2011 Wiley-Liss, Inc.
Characterizing protein glycosylation sites through higher‐energy C‐trap dissociation (2010)

Assigning glycosylation sites of glycoproteins and their microheterogeneity is still a very challenging analytical task despite the rapid advancements in mass spectrometry. It is shown here that glycopeptide ions can be fragmented efficiently using the higher-energy C-trap dissociation (HCD) feature of a linear ion trap orbitrap hybrid mass spectrometer (LTQ Orbitrap). An attractive aspect of this dissociation option is the generation of distinct Y1 ions (peptide+GlcNAc), thus allowing unequivocal assignment of N-glycosylation sites of glycoproteins. The combination of the very informative collision-induced dissociation spectra acquired in the linear ion trap with the distinct features of HCD offers very useful information aiding in the characterization of the glycosylation sites of glycoproteins. The HCD activation energy needed to obtain optimum Y1 ions was studied in terms of glycan structure and charge state, and size and structure of the peptide backbone. The latter appeared to be primarily dictating the needed HCD energy. The distinct Y1 ion formation in HCD facilitated an easy assignment of such an ion and its subsequent isolation and dissociation through multiple-stage tandem mass spectrometry. The resulting MS(3) spectrum of the Y1 ion facilitates database searching and de novo sequencing thus prompting the subsequent identification of the peptide backbone and associated glycosylation sites. Moreover, fragment ions formed by HCD are detected in the Orbitrap, thus overcoming the 1/3 cut-off limitation that is commonly associated with ion trap mass spectrometers. As a result, in addition to the Y1 ion, the common glycan oxonium ions are also detected. The high mass accuracy offered by the LTQ Orbitrap mass spectrometer is also an attractive feature that allows a confident assignment of protein glycosylation sites and the microheterogeneity of such sites.
Transducing the genome: information, anarchy, and revolution in the biomedical sciences (2001)

This text provides a behind-the-scenes look at the sequencing of the human genome project and the birth of the science of genomics. It explains genomics as an information science and traces its history back further than standard histories and news accounts to the early visionaries who saw the gene as as information carrier. It covers the early protein work of leigh Anderson and John taylor to the entreprenerial ideas of protein chemist Randall Scott and his vision of mining the database of gene sequences for pharmaceutical riches. The book also looks at the developments that have come out of the human genome project and the birth of genomics, and how they will be influencing the world of science for years to come.
A generalized ray expansion method for analyzing the EM scattering by open-ended waveguide cavities (2003)

The high-frequency scattering from the interior of a relatively arbitrarily shaped open-ended waveguide cavity in free space is analyzed by a generalized ray expansion (GRE) method, when the cavity is terminated within by a planar boundary and illuminated by an external EM plane wave. In the GRE method, the aperture at the open end of the cavity is first divided into subapertures, and a cone of rays (or a fan of rays in the 2-D case) is shot within the cavity from each subaperture. The initial amplitudes of these rays can be found from the radiated far-field patterns of each of the subapertures in the absence of the slowly varying cavity walls. These rays, based on the GRE, implicitly contain the effects of the waves diffracted into the cavity via the edges at the open end without having to explicitly track the more cumbersome edge diffracted rays into the interior cavity region. The difference between the manner in which the GRE and the conventional geometrical optics methods launch rays within the cavity is illustrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The predominant themes as they appear in the different articles are discussed under these headings.
Recommendation of Online auction Items Focusing Collaborative Filtering (2007)

The rapid development of e-commerce has promoted the growth of online auctions business based on C2C context. However, the ever-increasing customer size and auctioned goods cause the problem of information overload, and how to enhance the customer loyalty becomes a critical issue faced by most online auctions websites. One way to overcome the problem is to use recommender systems to provide personalized information services. Since there exist much difference between B2C and C2C context, it is a new challenge for us to apply recommender systems to the latter setting. This paper analyzes the customer behaviors on the auction website and constructs the customer preference model under the C2C context. Then the collaborative filtering technique is used to recommend auction items.

The Identification and Field Bioassay of Chemical Attractants in the Roundheaded Pine Beetle1 (1976)

Analyses of volatiles from hindguts of D. adjunctus revealed the presence of frontalin with trans -verbenol in feeding females and exo -brevicomin in emergent males. In field tests, both frontal in and exo -brevicomin were attractive, whereas no response to trans -verbenol could be shown. Males were more responsive to frontalin than to exo -brevicomin, and females were more responsive to exo -brevicomin.
3GE-WLAN Vertical Handover Experience using Fast Mobile IPv6 (2008)

Recently, seamless vertical handover has become one of the challenging issues in wireless networks. Seamless handover enables mobile users to access on-going services without interruption as moving across various wireless networks. The vertical handover requires fast and efficient handover control over various wireless technologies to realize the service continuity and seamless mobility. In this paper, we propose novel vertical handover platform for 3G evolution which has characteristics of FMIPv6 based mobility management. The experimental result shows that our vertical handover platform is well-designed and suitable for seamless vertical handover.
