Statically and Dynamically Measured Poisson's Ratio of Granular Soils on Triaxial Laboratory Specimens (2013)

Abstract Poisson's ratios and small-strain stiffnesses of three kinds of granular materials—fine, medium coarse, and coarse sands—were evaluated in the laboratory. Both axial and radial strains of cylindrical triaxial specimens were measured with a local deformation transducer and clip gauges. Small-strain (≈0.001 %) cyclic loadings were applied in the vertical direction at several isotropic stress states. We determined Poisson's ratio statically based on the local strain variations during the cyclic loadings; we also investigated the stiffness in parallel. In conjunction with static measurements, elastic waves were propagated. By utilizing the disk transducer method, we were able to measure both compressional and shear waves in a single specimen under identical stress states. Based on the received wave velocities of compressional and shear waves, we were able to evaluate both Poisson's ratio and the small-strain stiffness dynamically. We then compared elastic parameters evaluated both statically and dynamically for the geo-materials.

Supramolecular Packing Controls H2 Photocatalysis in Chromophore Amphiphile Hydrogels (2015)

Light harvesting supramolecular assemblies are potentially useful structures as components of solar-to-fuel conversion materials. The development of these functional constructs requires an understanding of optimal packing modes for chromophores. We investigated here assembly in water and the photocatalytic function of perylene monoimide chromophore amphiphiles with different alkyl linker lengths separating their hydrophobic core and the hydrophilic carboxylate headgroup. We found that these chromophore amphiphiles (CAs) self-assemble into charged nanostructures of increasing aspect ratio as the linker length is increased. The addition of salt to screen the charged nanostructures induced the formation of hydrogels and led to internal crystallization within some of the nanostructures. For linker lengths up to seven methylenes, the CAs were found to pack into 2D crystalline unit cells within ribbon-shaped nanostructures, whereas the nine methylene CAs assembled into long nanofibers without crystalline molecular packing. At the same time, the different molecular packing arrangements after charge screening led to different absorbance spectra, despite the identical electronic properties of all PMI amphiphiles. While the crystalline CAs formed electronically coupled H-aggregates, only CAs with intermediate linker lengths showed evidence of high intermolecular orbital overlap. Photocatalytic hydrogen production using a nickel-based catalyst was observed in all hydrogels, with the highest turnovers observed for CA gels having intermediate linker lengths. We conclude that the improved photocatalytic performance of the hydrogels formed by supramolecular assemblies of the intermediate linker CA molecules likely arises from improved exciton splitting efficiencies due to their higher orbital overlap.

On nonadiabatic coupling vectors in time-dependent density functional theory (2009)

In this note, we show that the development for the calculation of nonadiabatic coupling vectors in the framework of TDDFT introduced by the authors in the series of recent publications [E. Tapavicza et al., Phys. Rev. Lett.98, 023001 (2007); I. Tavernelli et al., J. Chem. Phys.130, 124107 (2009)] is rigorous and fully equivalent to the one proposed by Sugino and co-workers [C. P. Hu et al., J. Chem. Phys.127, 064103 (2007)]. Specific applications of our formulation are also discussed.
Alternate Approach to Prediction of IC Failures Using Silicon Based Degradation Mechanisms (2018)

Microcircuits designed and manufactured with advanced Complementary Metal Oxide Semiconductor (CMOS) technology, i.e., with feature sizes less than 50 nanometers (nm), are susceptible to early wearout. Traditionally, this has not been a serious concern for most commercial, industrial, and consumer products because the wearout did not occur within the typical lifetimes of the products, and because their operating conditions were relatively benign. Since those markets are large, microcircuit manufacturers targeting them have taken the necessary steps to assure that wearout is not a serious problem for their targeted customers. Aerospace, defense, and high performance (ADHP) products are different: service lifetimes can be decades long, operating conditions are rugged, and consequences of failure are high. Furthermore, aerospace markets are typically too small to warrant the attention and interest of the microcircuit manufacturers who target their products for commercial, industrial, and consumer markets. This paper describes how the ADHP industries have addressed microcircuit wearout through research to understand the problem; to develop analytical methods and software to quantify the effects of wearout in ADHP electronics system designs; and to use the results in system safety, certification, and reliability analyses. The results of the research and development described here have been captured in an Aerospace Recommended Practice (SAE ARP6338), that standardizes a common approach to analyze and mitigate the effects of early microcircuit wearout in ADHP applications. The ARP6338 process has been incorporated into a software tool.
Design, fabrication, and high-gradient testing of an X-band, traveling-wave accelerating structure milled from copper halves (2018)

A prototype 11.994 GHz, traveling-wave accelerating structure for the Compact Linear Collider has been built, using the novel technique of assembling the structure from milled halves. The use of milled halves has many advantages when compared to a structure made from individual disks. These include the potential for a reduction in cost, because there are fewer parts, as well as a greater freedom in choice of joining technology because there are no rf currents across the halves' joint. Here we present the rf design and fabrication of the prototype structure, followed by the results of the high-power test and post-test surface analysis. During high-power testing the structure reached an unloaded gradient of 100 MV=m at a rf breakdown rate of less than 1.5 10 -5 breakdowns=pulse=m with a 200 ns pulse. This structure has been designed for the CLIC testing program but construction from halves can be advantageous in a wide variety of applications.
Improvement of Charpy Impact of Carbon Fiber Reinforced Polymer by Low Energy Sheet Electron Beam Irradiation (2006)

Effects of sheet electron beam irradiation under low potential on the Charpy impact value of carbon fiber reinforced polymer (CFRP) have been investigated. The irradiation, which is one of short-time treatments, enhances the impact value of CFRP. It probably depends on the enhancement of interfacial force, as well as the strengthening of carbon fiber and polymer.

Epidermal cells adhere preferentially to type IV (basement membrane) collagen. (1979)

Epidermal cells from adult guinea pig skin attach and differentiate preferentially on substrates of type IV (basement membrane) collagen, compared to those of types I--III collagen. In contrast, guinea pig dermal fibroblasts attach equally well to all four collagen substrates. Fibronectin mediates the attachment of fibroblasts but not of epidermal cells to collagen.
High-performance CO2 sorbents from algae (2012)

Highly porous N-doped carbon materials with apparent surface areas in the 1300–2400 m2 g−1 range and pore volumes up to 1.2 cm3 g−1 have been synthesized from hydrothermal carbons obtained from mixtures of algae and glucose. The porosity of these materials is made up of uniform micropores, most of them having sizes <1 nm. Moreover, they have N contents in the 1.1–4.7 wt% range, and the heteroatom is mainly a pyridone-type structure. These microporous carbons present unprecedented large CO2 capture capacities, up to 7.4 mmol g−1 (1 bar, 0 °C). The importance of the pore size on the CO2 capture capacity of microporous carbon materials is clearly demonstrated. Indeed, a good correlation between the CO2 capture capacity at sub-atmospheric pressure and the volume of narrow micropores is observed. The results suggest that pyridinic-N, pyridonic/pyrrolic-N and quaternary-N do not contribute significantly to the CO2 adsorption capacity, owing probably to their low basicity in comparison with amines. These findings will help the design of high-performance CO2 capture sorbents.

Multi-tag RFID systems (2007)

Successful object identification is the primary objective of Radio Frequency Identification (RFID) technology. Yet, a recent major study by Wal-Mart has shown that object detection probability can be as low as 66%. We propose the tagging of objects with multiple tags to address the fundamental issue of object detectability. We show that this strategy dramatically improves the efficacy of RFID systems, even in the face of radio noise and other interfering factors. We define different types of multi-tag systems and examine their benefits using analytics, simulations, and experiments with commercial RFID equipment. We investigate the effect of multi-tags on anti-collision algorithms, and develop several techniques that enable multi-tags to enhance RFID security. We suggest new promising applications of multi-tags, ranging from improving patient safety to preventing illegal deforestation. We analyse the economics of multi-tag RFID systems and argue that the benefits of multi-tags will continue to increasingly outweigh their costs in many applications.
High efficiency superconducting field effect devices for oxide electronic applications (2019)

Abstract We present a study of the efficiency of LaAlO 3 /SrTiO 3 nanoscale field effect devices realized in the side gate configuration. We show that a change in the resistance of more than four orders of magnitude and a voltage gain of up to 50 can be obtained with the application of a gate voltage smaller than 1V. At dilution temperatures, the nanodevices become superconducting and we demonstrate the possibility to obtain a superconductor to insulator transition by applying only 200 mV. These results are discussed in the view of applications for quantum electronics.

Pasteurella multocida toxin stimulates mitogenesis and cytoskeleton reorganization in Swiss 3T3 fibroblasts (1996)

Pasteurella multocida toxin (PMT) causes cytoplasmic retraction in epithelial cells, activates osteoclast neoformation, and is a potent mitogen for Swiss 3T3 fibroblasts. In the present study designed to further investigate the effects of PMT on cell shape and proliferation, we report that the mitogenic effect of affinity-purified PMT on quiescent 3T3 cells was even superior at 5 ng/ml to that of fetal bovine serum or bombesin. This positive effect was inhibited by heat denaturation and methylamine treatment (this agent blocks internalization). Preincubation of PMT with gangliosides GM1, GM2, or GM3 counteracted its effect on DNA synthesis, suggesting that the toxin binds to GM-type ceramides on target cells. The distribution of F-actin was analyzed in control/treated cells using FITC-conjugated phalloidin. In comparison with FBS and bombesin, PMT triggered a more rapid and profound reorganization of cortical actin into prominent stress fibers after only 5–10 min. This event lead to the retraction of cells after only 30 min and ultimately to the induction of mitotic figures. Interestingly, methylamine blocked the effects of PMT on stress fiber formation and cell retraction but not the ruffling response, suggesting that some early events may not require toxin internalization. In summary, these findings indicate that PMT concomitantly exerts a strong mitogenic activity and a rapid stimulation of cytoskeletal rearrangements, possibly after binding to membrane gangliosides and subsequent internalization. We propose that this toxin could be used in the future as a defined inducer of transduction signals involved in cellular proliferation and control of cell shape. © 1996 Wiley-Liss, Inc.
Capacity of time-space switched cellular radio link systems for metropolitan area networks (1992)

Using multipoint-radio link systems constitutes a viable alternative to copper and optical fibres for high-capacity local distribution of telephone and data traffic. In the paper, a novel architecture for a fixed cellular radio system is proposed. The proposed system uses electronically steerable antennas to combine time and ‘space’ multiplexing. Assuming an urban environment and a high user density, the performance of the system is estimated for some simple propagation and interference models. Results indicate that, owing to the time-space multiplexing technique, the performance exceeds the performance of conventional multipoint systems by an order of magnitude. Owing to the unique features of the system, several central stations may be operated at the same site at the same frequency, to boost the capacity even more.
Blood oxygen level dependent response and spatial working memory in adolescents with alcohol use disorders - eScholarship (2004)

Background: Previous studies have suggested neural disruption and reorganization in young and older adults with alcohol use disorders (AUD). However, it remains unclear at what age and when in the progression of AUD changes in brain functioning might occur. Methods: Alcohol use disordered (n = 15) and nonabusing (n = 19) boys and girls aged 15 to 17 were recruited from local high schools. Functional magnetic resonance imaging data were collected after a minimum of 5 days' abstinence as participants performed spatial working memory and simple motor tasks. Results: Adolescents with AUD showed greater brain response to the spatial working memory task in bilateral parietal cortices and diminished response in other regions, including the left precentral gyros and bilateral cerebellar areas (clusters 943 mul; p < 0.05), although groups did not differ on behavioral measures of task performance. No brain response differences were observed during a simple finger-tapping task. The degree of abnormality was greater for teens who reported experiencing more withdrawal or hangover symptoms and who consumed more alcohol. Conclusions: Adolescents with AUD show abnormalities in brain response to a spatial working memory task, despite adequate performance, suggesting that subtle neuronal reorganization may occur early in the course of AUD.
Augmented reality camera tracking with homographies (2002)

To realistically integrate 3D graphics into an unprepared environment, camera position must be estimated by tracking natural image features. We apply our technique to cases where feature positions in adjacent frames of an image sequence are related by a homography, or projective transformation. We describe this transformation's computation and demonstrate several applications. First, we use an augmented notice board to explain how a homography, between two images of a planar scene, completely determines the relative camera positions. Second, we show that the homography can also recover pure camera rotations, and we use this to develop an outdoor AR tracking system. Third, we use the system to measure head rotation and form a simple low-cost virtual reality (VR) tracking solution.

Comparison of CaOH with MTA for Direct Pulp Capping (2013)

This practice-based, randomized clinical trial evaluated and compared the success of direct pulp capping in permanent teeth with MTA (mineral trioxide aggregate) or CaOH (calcium hydroxide). Thirty-five practices in Northwest PRECEDENT were randomized to perform direct pulp caps with either CaOH (16 practices) or MTA (19 practices). Three hundred seventy-six individuals received a direct pulp cap with CaOH (n = 181) or MTA (n = 195). They were followed for up to 2 yrs at regular recall appointments, or as dictated by tooth symptoms. The primary outcomes were the need for extraction or root canal therapy. Teeth were also evaluated for pulp vitality, and radiographs were taken at the dentist's discretion. The probability of failure at 24 mos was 31.5% for CaOH vs. 19.7% for MTA (permutation log-rank test, p = .046). This large randomized clinical trial provided confirmatory evidence for a superior performance with MTA as a direct pulp-capping agent as compared with CaOH when evaluated in a practice-based research network for up to 2 yrs.
A Tabu Search Algorithm For The Site Dependent Vehicle Routing Problem With Time Windows (2001)

This paper shows that the Site Dependent Vehicle Routing Problem (SDVRP) can be viewed as a special case of the Periodic VRP. A tabu search heuristic for the SDVRP and the SDVRP with Time Windows is outlined and tested on randomly generated instances. In the case of the SDVRP for which benchmark results are available, the proposed method outperforms all previously published algorithms.
Enhancing Directional Stability of Small-Scale Electric Vehicle with Steer-by-Wire System (2003)

This study proposes a new control system to enhance directional stability of small-scale electric vehicle by Steer-by-Wire (SBW) System. SBW has structure merits in avoiding interference between the driver and steering wheel since mechanical link between steering wheel and tire is replaced by electric wire system, consisting of sensors, steering actuators and controllers. To enhance stability against disturbance, steering control algorithm of SBW is proposed by using theory of disturbance observer. To improve straight-running stability, the controller is designed to regulate the yaw rate generated by asymmetric braking on μ-split road. The effectiveness of the proposed SBW is verified by computer simulation. Finally, the on-board system of experiment vehicle is introduced.
New Procedure for Making Schmidt Corrector Plates (1972)

We describe what we call the dioptric elasticity method of making Schmidt plates. An oversize disk is supported on a narrow metal ring. Within this ring, the air underneath is partially evacuated; a primary vacuum is formed under the outer annulus. The elastically deformed disk is worked flat. When the loads are removed, the disk takes on an excellent, smooth Kerber profile over the region interior to the supporting ring. This produces more highly aspherical surfaces (F/1) and is more convenient than the method attempted by Schmidt. We give the elasticity theory, discuss our shop methods, and show the very satisfactory results.
