Stability and safety analysis of the air-lifted catamaran (2008)

Abstract The air-lifted catamaran (ALC) is an innovative fast marine transportation concept, comprising the application and variation of a new, skirtless air cushion and air-lubrication, thus rendering it a hybrid between catamaran and surface effect ship (SES). Its features and capabilities are beyond current conventional high-speed monohull and catamaran. The present paper presents pertinent studies on stability concerning this craft, including dynamic stability, stability in turning and directional stability. The stability analysis takes into account air compressibility in the cushion, and is carried out in time domain. Some simulated results are presented and discussed, and requirements for design and operation of the craft based on IMO HSC Code 2000 are briefly outlined.
Voltage oscillation associated with nonlinear conductivity in the organic conductor α-(BEDT-TTF)2I3 (2010)

Characteristic voltage oscillation phenomenon is observed in an organic conductor α-[bis(ethylenedithio)tetrathiafulvalene]2I3, in the nonlinear conductivity region below the metal-insulator transition at 135 K. The oscillation, which is clearly visible in the wave form, appears only when the current is applied in the direction of the charge alternation in the two-dimensional stripe charge order. The frequency of order 10 kHz increases linearly with the applied current. These aspects are interpreted from the viewpoint of collective motion of the two-dimensional charge order.
Current Methods for Laboratory Analysis of Environmental Levels of Radioactivity (1976)

This paper reviews the current methods for laboratory analysis of environmental levels of radioactivity and discusses the background, Compton scatter, and efficiency parameters that are associated with the various spectrometer systems. The methods which are discussed are: 1) total absorption gamma-ray spectrometry, 2) multidimensional gamma-ray spectrometry, and 3) multidimensional gamma-ray spectrometry with dual beta coincidence (all systems use NaI(Tl) detectors). Dual Ge(Li) anticoincidence shielded systems as well as NaI(Tl) and Ge(Li) coincidence gamma-ray spectrometers are discussed. The analysis of X-ray and alpha emitters is pursued for both laboratory and field detector systems. The special adaptation of some gamma-ray, X-ray and alpha spectroscopy systems to field utilization including underwater analysis is presented.

Functional Transcriptomics of Wild-Caught Lutzomyia intermedia Salivary Glands: Identification of a Protective Salivary Protein against Leishmania braziliensis Infection (2013)

We identified the most abundant and novel proteins present in the SGs of Lu. intermedia, a vector of cutaneous leishmaniasis in the Americas. We also show for the first time that immunity to a single salivary protein from Lu. intermedia can protect against cutaneous leishmaniasis caused by L. braziliensis.
Site-Specific Incorporation of Unnatural Amino Acids into Escherichia coli Recombinant Protein: Methodology Development and Recent Achievement (2019)

More than two decades ago a general method to genetically encode noncanonical or unnatural amino acids (NAAs) with diverse physical, chemical, or biological properties in bacteria, yeast, animals and mammalian cells was developed. More than 200 NAAs have been incorporated into recombinant proteins by means of non-endogenous aminoacyl-tRNA synthetase (aa-RS)/tRNA pair, an orthogonal pair, that directs site-specific incorporation of NAA encoded by a unique codon. The most established method to genetically encode NAAs in <i>E</i><i>scherichia</i><i>coli</i> is based on the usage of the desired mutant of <i>Methanocaldococcus</i><i>janaschii</i> tyrosyl-tRNA synthetase (<i>Mj</i>TyrRS) and cognate suppressor tRNA. The amber codon, the least-used stop codon in <i>E. coli</i>, assigns NAA. Until very recently the genetic code expansion technology suffered from a low yield of targeted proteins due to both incompatibilities of orthogonal pair with host cell translational machinery and the competition of suppressor tRNA with release factor (RF) for binding to nonsense codons. Here we describe the latest progress made to enhance nonsense suppression in <i>E. coli</i> with the emphasis on the improved expression vectors encoding for an orthogonal aa-RA/tRNA pair, enhancement of aa-RS and suppressor tRNA efficiency, the evolution of orthogonal EF-Tu and attempts to reduce the effect of RF1.
Fabrication and biocompatibility of cell scaffolds of poly(L‐lactic acid) and poly(L‐lactic‐co‐glycolic acid) (2002)

Abstract In this paper, poly( L ‐lactic acid) (PLLA) and poly( L ‐lactic‐co‐glycolic acid) (PLGA) were synthesized, and the biocompatibility of PLGA(50/50) (molar ratio) was evaluated by observing the tissue response during implanting PLGA(50/50) into rats. After the PLGA(50/50) was implanted into rats for 12 weeks, the lymphocytes and plasma cells became small or disappeared at the muscle tissue of implant site which indicates the biocompatibility of PLGA(50/50) is very good. A series of porous cell scaffolds of PLGA and PLLA were prepared by using a solution‐casting/salt‐leaching technique. An improved method in which a density bottle instead of a graduated cylinder was developed to measure their porosities. It was found that the accuracy and reproducibility of the improved method for measuring porosity are excellent. A porous PLGA(50/50) scaffold was used to study chondrocytes culture. The chondrocytes were proliferated in porous PLGA(50/50) scaffold and the composite cell/PLGA was successfully obtained for cartilage regeneration. Copyright © 2002 John Wiley &amp; Sons, Ltd.
Out-of-Plane Sulfur Distortions in the Bi4O4S3 Superconductor (2021)

The local atomic structure of the non-magnetic layered superconductor Bi4O4S3 was investigated using neutron diffraction and pair density function (PDF) analysis. Although on average, the crystal structure is well ordered, evidence for local, out–of–plane sulfur distortions is provided, which may act as a conduit for charge transfer from the SO4 blocks into the superconducting BiS2 planes. In contrast with LaO1−xFxBiS2, no sulfur distortions were detected in the planes, which indicates that charge density wave fluctuations are not supported in Bi4O4S3.
Derivation of a Roe Scheme for an N-Species Chemically Reacting Gas in Thermal Equilibrium (1990)

A Roe-type flux-difference-splitting scheme is developed for an N-species chemically reacting gas in 3D. Thermal equilibrium is assumed. By focusing on the construction of the numerical flux function, it is shown that many details of the construction method are eventually unimportant and this observation leads to much more simple expressions for the numerical flux function than generally encountered in the literature. As a special type case (n=1), a Roe scheme is also presented for a thermally perfect gas.
Elastic and Piezoelectric Properties of Potassium Lithium Niobate (KLN) Crystals (1978)

The KLN crystal K2.89Li1.55Nb5.11O15 was pulled from the melt. Piezoelectric and elastic constants were measured from room temperature to about 120°C by observing resonant and antiresonant frequencies of bars and plates. The electromechanical coupling factors k15, k31, k33 and kt were 0.34, 0.18, 0.52 and 0.53 respectively. The temperature coefficients of elastic compliances Ts33E and Ts66E were fairly small and were -0.98 and 0.075×10-4/°C, respectively.

dSensingNI (2012)

This work presents an approach to overcome the disadvantages of existing interaction frameworks and technologies for touch detection and object interaction. The robust and easy to use framework dSensingNI (Depth Sensing Natural Interaction) is described, which supports multitouch and tangible interaction with arbitrary objects. It uses images from a depth-sensing camera and provides tracking of users fingers of palm of hands and combines this with object interaction, such as grasping, grouping and stacking, which can be used for advanced interaction techniques.
Demonstration of a continuously variable true-time delay beamformer using a multichannel chirped fiber grating (2006)

A continuously variable true-time delay beamformer based on a multichannel chirped fiber grating (MCFG) is demonstrated. The beamformer is capable of wide-band squint-free operation and demonstrates beam steering of a four-element array over /spl plusmn/40/spl deg/. The use of an MCFG provides a significant reduction in the length of the chirped grating required, eliminates spurious signal transmission, and utilizes narrow-band tunable laser sources. In addition, the effect of grating errors on the antenna pattern is examined and the tolerance on performance is presented.
Computer-assisted Visualization of Arteriovenous Malformations on the Home Personal Computer (2001)

Computer-assisted, three-dimensional visualizations of complex vascular anatomy can be helpful in planning the surgical excision of AVMs. Software programs that produce these images can provide important information that is difficult to obtain by traditional techniques. This imaging method is also applicable to guidance of endovascular procedures and removal of complex tumors.
Energy efficient engine, high pressure turbine thermal barrier coating. Support technology report (1983)

This report describes the work performed on a thermal barrier coating support technology task of the Energy Efficient Engine Component Development Program. A thermal barrier coating (TBC) system consisting of a Ni-Cr-Al-Y bond cost layer and ZrO2-Y2O3 ceramic layer was selected from eight candidate coating systems on the basis of laboratory tests. The selection was based on coating microstructure, crystallographic phase composition, tensile bond and bend test results, erosion and impact test results, furnace exposure, thermal cycle, and high velocity dynamic oxidation test results. Procedures were developed for applying the selected TBC to CF6-50, high pressure turbine blades and vanes. Coated HPT components were tested in three kinds of tests. Stage 1 blades were tested in a cascade cyclic test rig, Stage 2 blades were component high cycle fatigue tested to qualify thermal barrier coated blades for engine testing, and Stage 2 blades and Stage 1 and 2 vanes were run in factory engine tests. After completion of the 1000 cycle engine test, the TBC on the blades was in excellent condition over all of the platform and airfoil except at the leading edge above midspan on the suction side of the airfoil. The coating damage appeared to be caused by particle impingement; adjacent blades without TBC also showed evidence of particle impingement.
Performance analysis of Union and CoW File Systems with Docker (2016)

One of the biggest challenges that we face today in file systems is balancing performance, durability and consistency. With data growing beyond what was anticipated a decade ago, we need solutions and better file system. The new applications, platforms and systems currently built depend heavily on the file system for performance. One of such new platform is Docker, which is an open source project that enables Linux applications to be packaged as containers without typical overheads of virtual machines. This paper gives performance analysis and comparison of a file systems called as Unioning File Systems and Copy-onwrite File Systems. These file systems are used to provide core features of Docker storage. Docker follows a pluggable architecture which allows user to select the storage driver according to their need. This paper will give a clear picture and help the users in selecting the Docker storage driver according to the use case they are planning to implement in production.
Mining biochemical information: Lessons taught by the ribosome (2002)

The publication of the crystal structures of the ribosome offers an opportunity to retrospectively evaluate the information content of hundreds of qualitative biochemical and biophysical studies of these structures. We assessed the correspondence between more than 2,500 experimental proximity measurements and the distances observed in the ribosomal crystals. Although detailed experimental procedures and protocols are unique in almost each analyzed paper, the data can be grouped into subsets with similar patterns and analyzed in an integrative fashion. We found that, for crosslinking, footprinting, and cleavage data, the corresponding distances observed in crystal structures generally did not exceed the maximum values expected (from the estimated length of the agent and maximal anticipated deviations from the conformations found in crystals). However, the distribution of distances had heavier tails than those typically assumed when building three-dimensional models, and the fraction of incompatible distances was greater than expected. Some of these incompatibilities can be attributed to the experimental methods used. In addition, the accuracy of these procedures appears to be sensitive to the different reactivities, flexibilities, and interactions among the components. These findings demonstrate the necessity of a very careful analysis of data used for structural modeling and consideration of all possible parameters that could potentially influence the quality of measurements. We conclude that experimental proximity measurements can provide useful distance information for structural modeling, but with a broad distribution of inferred distance ranges. We also conclude that development of automated modeling approaches would benefit from better annotations of experimental data for detection and interpretation of their significance.
Effect of an Electric Field on Silicon Oxidation (1962)

Modified-marker experiments have shown that silicon oxidation is controlled by the diffusion of oxygen through the silicon dioxide film. The application of an electric field across the silicon dioxide layer enhances oxidation when the silicon is made positive with respect to the oxide—gas interface, and retards oxidation when the silicon is negative with respect to the oxide—gas interface. Oxidation under a retarding electric field ceases when the voltage developed across the growing oxide is equivalent to the change in free energy of the oxidation reaction. The dependence of the oxidation rate on an electric field indicates that oxygen ions are the predominant species diffusing through the growing oxide film.
Myeloma patients with COVID‐19 have superior antibody responses compared to patients fully vaccinated with the BNT162b2 vaccine (2021)

Patients with multiple myeloma (MM) have a suboptimal antibody response following vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and lower seroconversion rates following coronavirus disease 2019 (COVID-19) compared with healthy individuals. In this context, we evaluated the development of neutralising antibodies (NAbs) against SARS-CoV-2 in non-vaccinated patients with MM and COVID-19 compared with patients after vaccination with two doses of the BNT162b2 vaccine. Serum was collected either four weeks post confirmed diagnosis or four weeks post a second dose of BNT162b2. NAbs were measured with a Food and Drug Administration-approved enzyme-linked immunosorbent assay methodology. Thirty-five patients with COVID-19 and MM along with 35 matched patients were included. The two groups did not differ in age, sex, body mass index, prior lines of therapy, disease status, lymphocyte count, immunoglobulin levels and comorbidities. Patients with MM and COVID-19 showed a superior humoral response compared with vaccinated patients with MM. The median (interquartile range) NAb titre was 87·6% (71·6-94%) and 58·7% (21·4-91·8%) for COVID-19-positive and vaccinated patients, respectively (P = 0·01).Importantly, there was no difference in NAb production between COVID-19-positive and vaccinated patients who did not receive any treatment (median NAb 85·1% vs 91·7%, P = 0·14). In conclusion, our data indicate that vaccinated patients with MM on treatment without prior COVID-19 should be considered for booster vaccine doses.
Measuring the quality of pressure ulcer prevention: A systematic mapping review of quality indicators (2017)

The aim of this study was to provide a systematic overview of available pressure ulcer prevention quality indicators and to evaluate the underlying empirical evidence. A systematic mapping review was conducted with combined searches in Embase and Medline, and websites of relevant institutions and organisations. The eligibility criteria were clear use of the term "quality indicator" regarding pressure ulcer prevention; English or German language; and all settings, populations, and types of resources, including articles, brochures, and online material. In total, n = 146 quality indicators were identified. Most indicators were published in the United States (n = 50). The majority of indicators was developed for the hospital setting (n = 102). Process indicators were the most common (n = 71), followed by outcome indicators (n = 49). Less than half of identified indicators appeared to be practically used. Evidence supporting the validity and reliability were reported for n = 25 and n = 30 indicators respectively. The high number of indicators demonstrate the importance of measuring pressure ulcer prevention quality. This is not an indicator of our ability to accurately measure and evaluate this construct. There is an urgent need to develop evidence-based and internationally comparable indicators to help improve patient care and safety worldwide.
Neural Analogical Matching (2021)

Analogy is core to human cognition. It allows us to solve problems based on prior experience, it governs the way we conceptualize new information, and it even influences our visual perception. The importance of analogy to humans has made it an active area of research in the broader field of artificial intelligence, resulting in data-efficient models that learn and reason in human-like ways. While cognitive perspectives of analogy and deep learning have generally been studied independently of one another, the integration of the two lines of research is a promising step towards more robust and efficient learning techniques. As part of a growing body of research on such an integration, we introduce the Analogical Matching Network: a neural architecture that learns to produce analogies between structured, symbolic representations that are largely consistent with the principles of Structure-Mapping Theory.
Sensorless Speed Control of PMSMs based on an Improved Particle Filter (2019)

Position sensors in permanent magnet synchronous motor (PMSM) are restrained in some applications because of the space restriction and the reliability of the system. A marginalized particle filter (MPF) can used to staminate the speed of the motor by combining a Kalman filter (KF) with a particle filter (PF). In the MPF algorithm, the rotor position of the permanent magnet synchronous motor (PMSM) is represented by a set of particles, and the rotor speed associated with each particle is estimated by using the KF. The PF here is used to handle the non-Gaussianity and nonlinearity of the system. In this paper, the uniform distribution of particles is proposed to replace the traditional Gaussian distribution of particles in the PF to get better performance at the low-speed range. The motor drive system prototype is built using a TMS320F28335 digital signal processor as a controller core. The proposed improved PF is used in the sensorless speed vector control PMSM system. The experimental results show that the proposed PF with a uniform distribution of initial particles enables more accurate speed estimation in the low-speed range compared to the conventional Gaussian distribution, while increasing number of particles also helps to improve the accuracy.
Mechanisms and performance of metal oxide resistive RAM (RRAM) (2013)

Resistive RAM (RRAM) has emerged as a promising nonvolatile memory solution. Significant progress has been made on RRAM fabrication and characterization, as well as the understanding of the physical mechanisms. There are large varieties of RRAM materials and devices. However, some common characteristics have been observed in these devices, which can be attributed to the RRAM switching mechanisms. This tutorial will review RRAM switching models, based on which RRAM properties and performance can be analyzed. Tradeoffs among key device parameters are important for realistic assessment of RRAM in potential application space. Reliability is considered a major challenge for RRAM devices. Issues in commonly used RRAM characterization techniques will also be discussed.
Envisioning a Transdisciplinary University (2014)

Achieving social and economic growth requires collaboration, especially in global health. If universities are to improve health globally, they will need to train students and to support faculty who can effectively collaborate with those from other disciplines and cultures.
Performance assessment of an opto-fluidic phantom mimicking porcine liver parenchyma (2012)

An implantable, optical oxygenation and perfusion sensor to monitor liver transplants during the two-week period following the transplant procedure is currently being developed. In order to minimize the number of animal experiments required for this research, a phantom that mimics the optical, anatomical, and physiologic flow properties of liver parenchyma is being developed as well. In this work, the suitability of this phantom for liver parenchyma perfusion research was evaluated by direct comparison of phantom perfusion data with data collected from in vivo porcine studies, both using the same prototype perfusion sensor. In vitro perfusion and occlusion experiments were performed on a single-layer and on a three-layer phantom perfused with a dye solution possessing the absorption properties of oxygenated hemoglobin. While both phantoms exhibited response patterns similar to the liver parenchyma, the signal measured from the multilayer phantom was three times higher than the single layer phantom and approximately 21 percent more sensitive to in vitro changes in perfusion. Although the multilayer phantom replicated the in vivo flow patterns more closely, the data suggests that both phantoms can be used in vitro to facilitate sensor design.
75 GHz broadband Ti:LiNbO 3 optical modulatorwith ridge structure (1994)

The authors propose a Ti:LiNbO3 optical modulator employing a ridge structure with a thick electrode. The structure offers a low microwave propagation loss and strong interaction between microwaves and optical waves under conditions of velocity matching and impedance matching, resulting in a large modulation bandwidth and low driving voltage. Using this device, the authors have developed an optical intensity modulator with a 3 dB optical bandwidth of 75 GHz and a driving voltage of 5.0 V at 1.5 µm.
