Failures in power-combining arrays (1999)

We derive a simple formula for the change in output when a device fails in a power-combining structure with identical matched devices. The loss is written in terms of the scattering coefficient of the failed device and reflection coefficient of an input port in the combining network. We apply this formula to several power combiners, including arrays in free space and enclosed waveguide structures. Our simulations indicate the output power degrades gracefully as devices fail, which is in agreement with previously published results.
Polydopamine as a Versatile Adhesive Layer for Robust Fabrication of Smart Surface with Switchable Wettability for Effective Oil/Water Separation (2019)

A smart material with switchable surface wettability is highly desired for the practical application in removing oil from oily wastewater. In this work, we developed a robust and simple method to functionalize various substrate materials, such as a melamine sponge and nonwoven textile, with switchable surface oil wettability at varied media with different pHs. The modification method involves oxidative self-polymerization of dopamine on the material surface and subsequently functionalizing with a block copolymer, namely poly(2-vinylpyridine-b-dimethylsiloxane) (P2VP-b-PDMS). The as-functionalized materials display stable and continuous switchable wettability. The materials switch their wettability by simply responding to aqueous pH, and the switch is achieved at room temperature and involves no organic solvent. The materials show excellent oil/water separation performance for different kinds of oils and exhibit durability in strong alkaline and corrosive solutions. This robust and simple chemical modification strategy reduces the production cost of smart materials with switchable wettability and thus would lead to their mass production and applications toward solving practical industrial problems.
Security features in Windows Vista and IE7 – Microsoft's view (2006)

With the launch of Windows Vista a few months off, its security prowess is more than a matter of curiosity. Detractors such as Symantec are lining up. We look under the covers at the security features in the run-up to Microsoft's biggest operating system launch since XP hit the streets nearly five years ago. And while we're at it, IE7, also currently in beta, gets the treatment. As the article shows, one of the features Windows Vista introduces is a privilege brokering system named User Account Control which obviates the need to login interactively with what Microsoft sees as ‘excessive privilege’. The requirement for excessive privilege often stems from application developers who build code using privileged accounts and hence the software they produce often assumes a similar environment. Previous versions of Microsoft Windows have required privileged accounts to be used to change the system's TimeZone setting. This setting together with several others have been changed to enable control by regular users. With Windows Vista due to be released in early 2007, IT departments across the world are planning for the inevitable. Also currently in beta testing, Internet Explorer 7 is likely to be out by year-end. What can be expected security-wise? Microsoft presents its case.
<i>p</i>−InP/<i>n</i>−CdS solar cells and photovoltaic detectors (1975)

We have prepared p−InP/n−CdS heterodiode photovoltaic detectors with a uniform quantum efficiency of ∼70% for wavelengths between 550 and 910 nm. On a cloudy day in New Jersey, (53 mW/cm2) solar power conversion efficiencies of 12.5% have been measured on cells provided with antireflection coatings.
Addressing optimization for loop execution targeting DSP with auto-increment/decrement architecture (1998)

Since most DSP applications access large amount of data stored in the memory, a DSP code generator must minimize the addressing overhead. In this paper, we propose a method for addressing optimization in loop execution targeted toward DSP processors with auto-increment/decrement feature in their address generation unit. Our optimization methods include a multi-phase data ordering and a graph-based address register allocation. The proposed approaches have been evaluated using a set of core algorithms targeted towards the TI TMS320C40 DSP processor. Experimental results show that our system is indeed more effective compared to a commercial optimizing DSP compiler.

Floating windfarms for shallow offshore sites (2003)

Offshore wind energy appears to be on the verge of a phase of enormous expansion to becoming a significant source of electricity for a number of countries in northern Europe. Dozens of large projects are planned and a significant number now have planning permission and firm construction dates. The projects built to date have been in shallow seas, of up to around 20m in depth, in the North and Baltic seas, with the planned projects extending the range to new seas and greater depths. However, numerous challenges remain in the greater depths, in particular relating to the necessary size of the support structures, the resulting wave loads, handling equipment and natural frequencies. At one point, the inherent advantages associated with a floating support structure (of compliance due to the flexible attachment to the ground) will match the additional costs due to complexity and novelty. Questions of course remain under what conditions this will be (water depth, sea climate, distance to shore) and whether offshore wind energy can be proven to be economic under those conditions anyway
Fabrication of highly ordered nanoporous alumina films by stable high-field anodization (2006)

Stable high-field anodization (1500–4000 A m−2) for the fabrication of highly ordered porous anodic alumina films has been realized in a H3PO4–H2O–C2H5OH system. By maintaining the self-ordering voltage and adjusting the anodizing current density, high-quality self-ordered alumina films with a controllable inter-pore distance over a large range are achieved. The high anodizing current densities lead to high-speed film growth (4–10 µm min−1). The inter-pore distance is not solely dependent on the anodizing voltage, but is also influenced by the anodizing current density. This approach is simple and cost-effective, and is of great value for applications in diverse areas of nanotechnology.
Thyrotropin-Releasing Hormone Stimulates Body Weight Gain and Increases Thyroid Hormones and Growth Hormone in Plasma of Cockerels (1984)

The effect of TRH on growth in 4-week-old cockerels was examined in two separate experiments. Daily injection of TRH via the brachial vein stimulated growth in 4-week-old cockerels over 17 days of treatment in the first experiment and over 25 days in the second. In the first experiment, TRH at 1.0 micrograms and 10.0 micrograms/bird caused significant (P less than 0.05) increases of 12.0% and 12.4%, respectively, in growth rate, whereas in the second experiment, only the 1.0 micrograms/bird level of TRH caused an increase (P less than 0.05). In each experiment, the increase in body weight gain was not TRH dose dependent, and neither feed consumption nor feed efficiency was affected. Possible involvement of pituitary hormones in TRH-stimulated growth in cockerels was studied in a separate experiment, and the effects of TRH on plasma T3, T4, and GH were examined. TRH was given iv at 0.1, 1.0, and 10.0 micrograms/bird daily for 5 days, and plasma T3, T4, and GH concentrations were measured 15, 60, and 180 min postinjection by RIA on days 1, 3, and 5. The responses of T3 and T4 to TRH were greatest on day 1, were diminished by days 3 and 5, and were not dose-related. Significant, not dose-related, elevations of plasma GH concentrations were obtained at all doses of TRH. Based on these results, we suggest that TRH has the ability to promote a significant increase in body weight gain in 4-week-old cockerels, and the stimulatory effects may be mediated through GH and/or thyroid hormones.
NG-methylarginine, and inhibitor of endothelium-derived nitric oxide synthesis, is a potent pressor agent in the guinea pig: Does nitric oxide regulate blood pressure in vivo? (1989)

Nitric oxide is a major endothelium-derived vascular smooth muscle relaxing factor; its synthesis from L-arginine is selectively inhibited by L-NG-methylarginine. To assess whether basal nitric oxide release contributes to blood pressure regulation in vivo, we have investigated the cardiovascular effects of L-NG-methylarginine in the anesthetized guinea pig. L-NG-methylarginine (0.1-10 mg/kg, i.v. bolus) elicited a sustained, dose-dependent, increase in arterial pressure and a moderate bradycardia. L-arginine (30 mg/kg i.v.) prevented or reversed the pressor effect of L-NG-methylarginine, while atropine (2 mg/kg) abolished the associated bradycardia. In contrast, L-arginine did not attenuate the pressor effect of norepinephrine or angiotensin. Our findings suggest that basal nitric oxide production is sufficient to modulate peripheral vascular resistance; hence nitric oxide may play a role in arterial pressure homeostasis.
The design and performance evaluation of alternative XML storage strategies (2002)

This paper studies five strategies for storing XML documents including one that leaves documents in the file system, three that use a relational database system, and one that uses an object manager. We implement and evaluate each approach using a number of XQuery queries. A number of interesting insights are gained from these experiments and a summary of the advantages and disadvantages of the approaches is presented.
Studies <i>in vitro</i> on the flavinylation of 6‐hydroxy‐<scp>d</scp>‐nicotine oxidase (1986)

The gene of 6‐hydroxy‐D‐nicotine oxidase (6‐HDNO), a flavoenzyme from Arthrobacter oxidans with covalently bound FAD, was expressed with the aid of an expression vector in a cell‐free coupled transcription‐translation system derived from Escherichia coli MZ9. Ultraviolet irradiation of the E. coli extract did not affect synthesis of the 6‐HDNO polypeptide nor total protein synthesis but enzymatic 6‐HDNO activity could not be detected. Addition of FAD to the irradiated cell extract restored the capability of the transcription‐translation assays to synthesize enzymatically active 6‐HDNO. However, enzymatic activity could not be restored on addition of FAD plus cell‐free extract to the ultraviolet‐inactivated assays after completion of apo‐6‐HDNO synthesis (60 min) nor to immunoprecipitates thereof. Under similar conditions, addition of [ 14 C]FAD did not increase the protein‐bound radioactivity. These results indicate that under conditions of limited FAD supply in the in vitro system a flavinless apo‐6‐HDNO‐polypeptide was synthesized. It was, however, not possible to bind the cofactor to the completed polypeptide chain. These findings argue for a cotranslational cofactor binding.
Applications and benefits of ceramic membranes (2003)

This article looks at the applications and benefits of ceramic membranes. It covers crossflow technologies, membrane elements and modules and recent developments in this segment of membrane technology. Also presented are examples that demonstrate the ability of ceramic membranes to concentrate process streams, recover valuable products, and increase yields — making them a cost-effective and often preferred method of filtration.
RF Linewidth in Monolithic Passively Mode-Locked Semiconductor Laser (2008)

We have analyzed theoretically and experimentally the linewidth of the first harmonic of the photocurrent (radio-frequency (RF) linewidth) in monolithic passively mode-locked semiconductor lasers. Due to the absence of restoring force, the timing jitter is directly related to the RF linewidth, avoiding possible underestimations made with conventional methods of phase noise measurement. The RF linewidth is also analytically related to the pulse characteristics using Haus's model. The timing stability performance of a promising two-section quantum-dot laser is presented using RF linewidth measurements. Experimental evolution of the RF linewidth with power and pulsewidth is finally compared to the analytical expression.
A Facile Strategy for Selective Incorporation of Phosphoserine into Histones (2013)

Phosphoserine incorporation: A general strategy for producing recombinant histones with site-specific serine phosphorylation is developed by engineering phosphoseryl-tRNA synthetase (SepRS) and elongation factor Tu (EF-Tu; see picture). Serine-phosphorylated nucleosomes provide direct evidence for crosstalk between phosphorylation and acetylation in histones.
Gait Biomechanics of Individuals with Transtibial Amputation: Effect of Suspension System (2014)

Prosthetic suspension system is an important component of lower limb prostheses. Suspension efficiency can be best evaluated during one of the vital activities of daily living, i.e. walking. A new magnetic prosthetic suspension system has been developed, but its effects on gait biomechanics have not been studied. This study aimed to explore the effect of suspension type on kinetic and kinematic gait parameters during level walking with the new suspension system as well as two other commonly used systems (the Seal-In and pin/lock). Thirteen persons with transtibial amputation participated in this study. A Vicon motion system (six cameras, two force platforms) was utilized to obtain gait kinetic and kinematic variables, as well as pistoning within the prosthetic socket. The gait deviation index was also calculated based on the kinematic data. The findings indicated significant difference in the pistoning values among the three suspension systems. The Seal-In system resulted in the least pistoning compared with the other two systems. Several kinetic and kinematic variables were also affected by the suspension type. The ground reaction force data showed that lower load was applied to the limb joints with the magnetic suspension system compared with the pin/lock suspension. The gait deviation index showed significant deviation from the normal with all the systems, but the systems did not differ significantly. Main significant effects of the suspension type were seen in the GRF (vertical and fore-aft), knee and ankle angles. The new magnetic suspension system showed comparable effects in the remaining kinetic and kinematic gait parameters to the other studied systems. This study may have implications on the selection of suspension systems for transtibial prostheses. Trial registration: Iranian Registry of Clinical Trials IRCT2013061813706N1.
Cyclin-D1-gene amplification is a more potent prognostic factor than its protein over-expression in human head-and-neck squamous-cell carcinoma (1997)

To evaluate the prognostic significance of cyclin D1 protein/gene expressions in human head-and-neck squamous-cell carcinoma (HNSCC), we examined amplification of the cyclin-D1 gene (CCND1) by the differential PCR method and over-expression of cyclin-D1 protein by immunohistochemistry in 45 paraffin-embedded sections from HNSCC. Amplification of CCND1 was found in 10 (22%) cases and over-expression of cyclin D1 was found in 24 (53%) cases. CCND1 amplification was also found in 3 (25%) of 12 cases of dysplastic lesions adjacent to HNSCC. The overall 5-year survival of patients with CCND1 amplification or with protein over-production was significantly lower than that of patients without (p < 0.0001 and p < 0.05, respectively). However, with multivariate analysis, only amplification of CCND1 retained an independent prognostic value (p = 0.0018). These suggest that CCND1 amplification occurs at early stages of HNSCC tumorigenesis and is a more useful prognostic factor than over-expression of cyclin D1 in HNSCC.
The Artemisinin Derivative Artesunate Inhibits Corneal Neovascularization by Inducing ROS-Dependent Apoptosis in Vascular Endothelial Cells (2013)

Low-Temperature Fabrication of High Quality Gate Insulator in Metal–Oxide–Semiconductor Capacitor Using Laser Annealing (2019)

This letter reports the fabrication of a high quality gate oxide for metal-oxide-semiconductor field-effect transistors using a continuous-wave blue laser. A thin Zr metal layer was inserted between the dielectric and substrate to increase laser absorption and reduce the interface layer. A simulation of laser irradiation showed that the metal layer insertion induces a significant increase in temperature during laser annealing compared with the dielectric without a metal layer. The laser annealed capacitor with a 1-nm-thick Zr metal layer showed superior electrical characteristics, such as high capacitance, low leakage current, low fixed charge density, and low interface state density. Based on these results and the economic advantage of blue laser diodes, this technique can be a solution for low temperature processes, such as monolithic 3-dimensional integration, where low temperature processes are required.
Eliminating the isoleucine biosynthetic pathway to reduce competitive carbon outflow during isobutanol production by Saccharomyces cerevisiae (2015)

The deletion of competitive pathways to reduce the outflow of carbon, including ILV1 deletion, is an important strategy for increasing isobutanol production by S. cerevisiae.
Development and Evaluation of Two Learning-Based Personalized Driver Models for Pure Pursuit Path-Tracking Behaviors (2018)

Establishing a personalized driver model to predict the driving behavior plays a significant role in the promotion of driver assistance system and automated driving system. In this paper, we propose two different learning-based pathtracking personalized driver models to predict the lookahead distance based on pure pursuit algorithm using the naturalistic driving data collected from BIT intelligent vehicle platform. Based on Gaussian Mixture Model (GMM), one stochastic driver model is the velocity-based Gaussian Mixture Regression (GMR) approach established by combining Gaussian classification process and Gaussian mixture regression, while another driver model is the general GMR approach. The predicting results obtained from the stochastic models are analyzed based on the numbers of GMM components. Statistical analyses show that both personalized driver models perform well, and the velocity-based GMR approach demonstrate higher accuracy than general GMR approach in predicting lookahead distance with the preferred number of the GMM components 10-12 and better performance in tracking the given path.
