Passive 5.8-GHz radio-frequency identification tag for monitoring oil drill pipe (2003)

This paper reports a new passive 5.8-GHz radio-frequency identification tag proposed for monitoring oil drill pipe (patent pending). The tag is to be inserted into the tool joint of the drill pipe in order to predict the pipe's lifetime and to provide inventory control. The tag requires a minimal incident power density of 13.5 mW/cm/sup 2/ to establish a link and transmit 64-bit coded information to the interrogating reader. The tag uses a circular patch etched on a 60-mil Duroid with /spl epsiv//sub r/=2.33 to receive the interrogating RF power and transmit the identification (ID) information simultaneously. An efficient Schottky diode is used to rectify the RF power to provide the DC power necessary to operate the "on-board" electronics. A p-i-n diode modulates the tag's ID code onto the 5.8-GHz carrier frequency. The tag's physical size has to be small so that it can be imbedded into the pipe without weakening the structure. It has been designed to withstand large pressures normal to its surface. The system was successfully demonstrated in the laboratory.
Dietary approaches that delay age-related diseases (2006)

Reducing food intake in lower animals such as the rat decreases body weight, retards many aging processes, delays the onset of most diseases of old age, and prolongs life. A number of clinical trials of food restriction in healthy adult human subjects running over 2-15 years show significant reductions in body weight, blood cholesterol, blood glucose, and blood pressure, which are risk factors for the development of cardiovascular disease and diabetes. Lifestyle interventions that lower energy balance by reducing body weight such as physical exercise can also delay the development of diabetes and cardiovascular disease. In general, clinical trials are suggesting that diets high in calories or fat along with overweight are associated with increased risk for cardiovascular disease, type 2 diabetes, some cancers, and dementia. There is a growing literature indicating that specific dietary constituents are able to influence the development of age-related diseases, including certain fats (trans fatty acids, saturated, and polyunsaturated fats) and cholesterol for cardiovascular disease, glycemic index and fiber for diabetes, fruits and vegetables for cardiovascular disease, and calcium and vitamin D for osteoporosis and bone fracture. In addition, there are dietary compounds from different functional foods, herbs, and neutraceuticals such as ginseng, nuts, grains, and polyphenols that may affect the development of age-related diseases. Long-term prospective clinical trials will be needed to confirm these diet-disease relationships. On the basis of current research, the best diet to delay age-related disease onset is one low in calories and saturated fat and high in wholegrain cereals, legumes, fruits and vegetables, and which maintains a lean body weight. Such a diet should become a key component of healthy aging, delaying age-related diseases and perhaps intervening in the aging process itself. Furthermore, there are studies suggesting that nutrition in childhood and even in the fetus may influence the later development of aging diseases and lifespan.
Design and Control of Vehicle Trailer with Onboard Power Supply (2015)

<div class="section abstract"><div class="htmlview paragraph">Typically, when someone needs to perform occasional towing tasks, such as towing a boat on a trailer, they have two choices. They can either purchase a larger, more powerful vehicle than they require for their regular usage, or they can rent a larger vehicle when they need to tow something. In this project, we propose a third alternative: a trailer with an on-board power supply, which can be towed by a small vehicle. This system requires a means of sensing how much power the trailer's power supply should provide, and an appropriate control system to provide this power. In this project, we design and model the trailer, a standard small car, and the control system, and evaluate the concept's feasibility. We have selected a suitable power source for the trailer, a DC motor, coupled directly to the trailer's single drive wheel, which allow us to dispense with the need for a differential. The trailer hitch is designed to include force sensing capability, to determine whether the trailer is moving under its own power or being towed by the vehicle. There is a control system, designed to maintain a zero force in the hitch, thus ensuring that the trailer is providing enough power. This system will enable someone with occasional towing needs to perform these tasks with their standard vehicle, and avoid the need for a larger vehicle.</div></div>
Identification of a heparin binding site and the biological activities of the laminin α1 chain carboxy‐terminal globular domain (1999)

The carboxy-terminal globular domain (G-domain) of the laminin α1 chain has been shown to promote heparin binding, cell adhesion, and neurite outgrowth. In this study, we defined the potential sequences originating from the G-domain of laminin α1 chain which possess these functional activities. A series of peptides were synthesized from the G-domain, termed LG peptides (LG-1 to LG-6) and were tested for their various biological activities. In the direct [3H]heparin binding assays, LG-6 (residues 2,335–2,348: KDFLSIELVRGRVK) mediated high levels of [3H]heparin binding, and this peptide also directly promoted cell adhesion and spreading, including B16F10, M2, HT1080, and PC12 cells. The peptide LG-6 also promoted the neurite outgrowth of PC12 cells, mouse granule cells, and chick telencephalic cells. An anti-peptide LG-6 antibody inhibited laminin-1 and peptide LG-6–mediated cell adhesion and neurite outgrowth. Furthermore, an anti-integrin α2 antibody also inhibited the cell adhesion activity. These results suggest that peptide LG-6 plays a functional role as a heparin binding site in the G-domain of the laminin α1 chain, and this sequence was thus concluded to play a crucial role in regulating cell adhesion and spreading and neurite outgrowth which is related to integrin α2.

Quantum well intermixing caused by nonstoichiometric InP (2002)

We study the thermal stability of InP-based quantum well hetero-structures in which the temperature of growth of one or more layers is slightly reduced in comparison to standard growth. We examine the enhancement of quantum well intermixing (QWI) using repeated isothermal anneals, and show that the enhancement is a transient effect due to a surplus of mobile defects grown-in to the low temperature (LT) layers. These defects are related to a surplus of group-V atoms, and are thought to be phosphorus interstitials. The resultant interdiffusion occurs at different rates on each sublattice, thereby causing an enhancement of local strains, as observed by X-ray diffraction.
IMS enhanced filter and action criteria (2007)

In current 3GPP specifications initial filter criteria (iFC) and also the Shared iFC (SiFC) optimization (optional in the specs) are defined as part of the user service profile; This is linked to the user in order to allow forwarding of the initial received request to the proper Application Server (AS) running the required service logic. That approach considers that all service logic is performed at the AS and then the only defined action for the iFC (when trigger conditions are met) is to forward the request to the AS. The specifications however allow for additional ldquocall control logicrdquo at the S-CSCF that is outside the scope of the iFC controls. This paper presents a solution consisting of extensions to the iFCs schema. This can be used as a way to enable such call control logic the S-CSCF. If SiFC are used, the only impacted network element (NE) would be the S-CSCF.
Membrane fusion activity of the influenza virus hemagglutinin: interaction of HA2 N-terminal peptides with phospholipid vesicles (1991)

We have investigated the interaction of a number of synthetic 20-residue peptides, corresponding to the HA2 N-terminus of the influenza virus hemagglutinin (X31 strain), with phospholipid vesicles and monolayers. Besides the wild-type sequence, two peptides were studied with mutations corresponding to those previously studied in entire HA's expressed in transfected cells [Gething et al., (1986) J. Cell. Biol. 102, 11-23]. These mutations comprised a single Glu replacement for Gly at the N-terminus ("El" mutant) or at position 4 ("E4") of the HA2 subunit and were shown to produce striking alterations in virus-induced hemolysis and syncytia formation, especially for E1. The X31 "wild-type" (wt) peptide and its E4 variant are shown here to have the capacity to insert into phosphatidylcholine (POPC) large unilamellar vesicle (LUV) membranes in a strictly pH-dependent manner, penetration being marginal at pH 7.4 and significant at pH 5.0. Bilayer insertion was evident from a shift in the intrinsic Trp fluorescence of the wt and E4 peptides and from the induction of calcein leakage from POPC LUV and correlated well with the peptides' ability at pH 5.0 to penetrate into POPC monolayers at initial surface pressures higher than 30 mN/m. By contrast, the E1 peptide was found, at pH 5.0, to bind less tightly to vesicles (assessed by a physical separation method) and to cause much less leakage of POPC LUV than the wt, even under conditions where the peptides were bound to approximately the same extent. Consistent with the correlation between leakage and penetration observed for the wt peptide at pH 5 versus 7, the E1 peptide, even at low pH, showed much less lipid-vesicle-induced shift of its Trp fluorescence than wt, caused a much slower rate of leakage of vesicle contents, and did not insert into POPC monolayers at surface pressures beyond 28.5 mN/m. Circular dichroism spectroscopy measurements of peptides in POPC SUV showed that the conformations of all three peptides are sensitive to pH, but only the wt and E4 peptides became predominantly alpha-helical at acid pH.
Fc-Optimized NKG2D–Fc Constructs Induce NK Cell Antibody-Dependent Cellular Cytotoxicity against Breast Cancer Cells Independently of HER2/neu Expression Status (2014)

The ability of NK cells to mediate Ab-dependent cellular cytotoxicity (ADCC) largely contributes to the clinical success of antitumor Abs, including trastuzumab, which is approved for the treatment of breast cancer with HER2/neu overexpression. Notably, only ∼25% of breast cancer patients overexpress HER2/neu. Moreover, HER2/neu is expressed on healthy cells, and trastuzumab application is associated with side effects. In contrast, the ligands of the activating immunoreceptor NKG2D (NKG2DL) are selectively expressed on malignant cells. In this study, we took advantage of the tumor-associated expression of NKG2DL by using them as target Ags for NKG2D-IgG1 fusion proteins optimized by amino acid exchange S239D/I332E in their Fc part. Compared to constructs with wild-type Fc parts, fusion proteins carrying the S239D/I332E modification (NKG2D-Fc-ADCC) mediated highly enhanced degranulation, ADCC, and IFN-γ production of NK cells in response to breast cancer cells. NKG2D-Fc-ADCC substantially enhanced NK reactivity also against HER2/neu-low targets that were unaffected by trastuzumab, as both compounds mediated their immunostimulatory effects in strict dependence of target Ag expression levels. Thus, in line with the hierarchically organized potential of the various activating receptors governing NK reactivity and due to its highly increased affinity to CD16, NKG2D-Fc-ADCC potently enhances NK cell reactivity despite the inevitable reduction of activating signals upon binding to NKG2DL. Due to the tumor-restricted expression of NKG2DL, NKG2D-Fc-ADCC may constitute an attractive means for immunotherapy especially of HER2/neu-low or -negative breast cancer.
Bedrijfsfitness bereikt ook minder actieve werknemer (2000)

Fitness- en andere bewegingsprogramma's, aangeboden zowel op als buiten het werk, zouden vooral de al actieve werknemer lokken. Dit blijkt maar ten dele waar. Deelnemers die regelmatig meedoen aan een fitnessprogramma zijn weliswaar vaker norm-actief dan niet-deelnemers, maar ook in deze groep haalt meer dan de helft de huidige normen voor gezond bewegen niet.
Phototherapeutic Keratectomy: Strategies and Results in 12 Eyes (1993)

As part of a multicenter study of excimer laser procedures, we performed phototherapeutic keratectomy (PTK) on 12 eyes in 11 patients. Three eyes had superficial corneal scarring, two Salzmann's degeneration, two Reis-Bückler's dystrophy; and one each with recurrent lattice dystrophy in a corneal graft, band keratopathy, recurrent erosion syndrome, after pterygium scarring, and contact-lens related keratopathy. Indications for treatment included poor visual acuity, severe glare symptoms, ocular surface discomfort, recurrent erosions, and monocular diplopia. Follow up ranged from 1 to 4 months. Best spectacle corrected visual acuity improved in ten eyes with no eyes suffering loss of best spectacle corrected visual acuity. A hyperopic refractive shift was found in eight of 12 treated eyes. Corneal surface regularity improved in six of 12 eyes and worsened in one eye as measured by computerized corneal topographic analysis. Ten patients (11 eyes) noted improvement in their visual perception and subjective symptoms. We review various strategies of phototherapeutic keratectomy designed to treat particular corneal disorders: patient selection criteria to optimize clinical outcome are reviewed as well.
Fibre-supported optical generation and deliveryof 60 GHz signals (1994)

A novel ‘frequency quadrupling’ technique for the optical generation and delivery via fibre of modulated 60 GHz band millimetre-wave signals is described. The technique requires only microwave frequency capability for the optical modulator and drive electronics, and these are readily available commercially. The frequency quadrupling technique is demonstrated experimentally with a high spectral purity 60 GHz signal obtained using a 15 GHz source and optical modulator.
A Fully Solid-Phase Synthesis of Biotinylated Glycoclusters (2008)

The fully solid-phase synthesis of chemically well-defined glycoclusters grafted to a topological cyclodecapeptide template is described. The orthogonally protected peptide backbone was first synthesized and cyclized on solid support using D-glutamic acid as first amino acid linked to the resin. After successive regioselective deprotection steps, biotins were coupled to the lower addressable domains of the scaffold, then carbohydrates-binding ligands were assembled as cluster on the upper domain using a chemoselective oxime-based strategy. This provides multitopic labeled glycopeptides which can be easily immobilized to streptavidin-coated surfaces for studying carbohydrate-protein interactions in glycomic researches.
Double Skin Façade: The State of Art on Building Energy Efficiency (2015)

One of the most important methods of saving energy in a building is by carefully designing its facade.A 'double skin facade' is optimally one of the best options in managing the interaction between the outdoors and the internal spaces.It also provides some architectural flexibility to the design.Double skin faç ade (DSF) building is one of the available energy conservation opportunities through recent intelligent buildings.The need to energy conservation and sustainable development in buildings is causing a new interest towards passive solar systems.This paper will survey the various types of double skin facades systems, exploring their features and functioning followed by a review of examples; both constructed and proposed, from different buildings.The paper will then assess and analyze recent research and examples to attempt to reach a conclusion as to whether with a double skin faç ade, minimizing energy consumption within building.Finally, double skin facade (DSF) has been proven to be highly useful and significant in current building developments.The only downside of double skin facade is that it is said to be more expensive than the traditional single glass facade.However, it is widely agreed by many experts that double skin facade (DSF) is more cost-effective in the long run.This is because it is long lasting and more durable as compared to the single glass facade
Physical and dosimetric aspects of a multileaf collimation system used in the dynamic mode for implementing intensity modulated radiotherapy (1998)

The use of a multileaf collimator in the dynamic mode to perform intensity modulated radiotherapy became a reality at our institution in 1995. Unlike treatment with static fields using a multileaf collimator, there are significant dosimetric issues which must be assessed before dynamic therapy can be implemented. We have performed a series of calculations and measurements to quantify head scatter for small fields, collimator transmission, and the transmission through rounded leaf ends. If not accounted for, these factors affect the delivered dose to the prostate by 5%-20% for a typical plan. Data obtained with ion chambers and radiographic film are presented for both 6 and 15 MV x-ray beams. The impact on the delivered dose of the mechanical accuracy of the multileaf collimator, achieved during leaf position calibration and maintained during dose delivery, is also discussed.
A high-speed low-power JFET pull-down ECL circuit (1991)

An active pull-down output stage that utilizes a composite junction FET (JFET), applied in a high-speed low-power emitter-coupled logic (ECL) circuit, is described. The composite JFET structure is produced by modifying the existing bipolar transistor layout so that a p-channel JFET is formed next to an n-p-n transistor without need of any extra process steps. This p-channel JFET is a four-terminal device: the intrinsic base region defines the channel, the two separate extrinsic bases become the source and drain, the emitter region is the primary gate, and the collector is used as the back gate. The JFET has the same doping profile as the n-p-n bipolar transistor in the intrinsic device region. Simulation results based on a 0.8- mu m double poly-Si, self-aligned bipolar technology indicate that the circuit with a typical loading at a power consumption of 1 mW per gate offers a 24% improvement in the pull-down delay and a 53% improvement in the load driving capability compared with the conventional ECL circuit.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Molecular Cloning of Rat Insulin-Like Growth Factor I Complementary Deoxyribonucleic Acids: Differential Messenger Ribonucleic Acid Processing and Regulation by Growth Hormone in Extrahepatic Tissues (1987)

Two classes of insulin-like growth factor I (IGF-I) cDNAs were isolated from an adult rat liver library using a human IGF-I cDNA probe. The two types of rat IGF-I cDNA differed by the presence or absence of a 52-base pair insert which altered the derived C-terminal amino acid sequence of the E peptide, but not the 3'-untranslated region or the sequence coding for the mature IGF-I protein. When probes derived from these cDNA clones were hybridized to Northern blots of rat mRNA, specific bands of 8.6, 2.1, and 1.0-1.4 kilobases were seen. Hybridization to poly(A)+ RNA from various tissues from GH-treated and control rats demonstrated an increase in IGF-I mRNA due to GH treatment in all tissues examined.
Air Ions and Human Performance (1978)

Abstract The effects of artificial negative or positive ionisation of the air on the performance of a number of psychomotor tasks was studied on 45 human subjects. The results indicate that negative ionisation is associated with a significant increment in performance as compared to controls whilst positive ionisation appears not to have any effect. Additionally it is noted that both positive and negative ionisalion appears to influence the amplitude of the normal circadian rhythm of performance. The possible mechanisms by which ionisation might exert an influence on performance and the possible practical importance of the circadian rhythm effect are discussed.
Flaw Imaging with Ultrasound: The Time Domain Topological Gradient Method (2005)

Finding the shape and position of flaws embedded in an elastic material given ultrasonic measurements performed with a linear array of sensors is a present day challenge in Non Destructive Evaluation. We propose a topological gradient method adapted to the transient nature of pulse‐echo techniques. The computation involves an adjoint problem that corresponds to a time reversal operation that strengthens the confidence into the method. Numerical results are shown that confirm the efficiency of this approach.

Surface Adsorption Affects the Performance of Alkaline Anion-Exchange Membrane Fuel Cells (2018)

Material interactions at the polymer electrolytes–catalyst interface play a significant role in the catalytic efficiency of alkaline anion-exchange membrane fuel cells (AEMFCs). In this work, the surface adsorption behaviors of the cation–hydroxide–water and phenyl groups of polymer electrolytes on Pd- and Pt-based catalysts are investigated using two Pd-based hydrogen oxidation catalysts—Pd/C and Pd/C-CeO2—and two Pt-based catalysts—Pt/C and Pt-Ru/C. The rotating disk electrode study and complementary density functional theory calculations indicate that relatively low coadsorption of cation–hydroxide–water of the Pd-based catalysts enhances the hydrogen oxidation activity, yet substantial hydrogenation of the surface adsorbed phenyl groups reduces the hydrogen oxidation activity. The adsorption-driven interfacial behaviors of the Pd- and Pt-based catalysts correlate well with the AEMFC performance and short-term stability. This study gives insight into the potential use of non-Pt hydrogen oxidation reaction catalysts that have different surface adsorption characteristics in advanced AEMFCs.
