Adherence of Probiotic Bacteria to Human Intestinal Mucus in Healthy Infants and during Rotavirus Infection (2001)

The concentration of fecal mucin and the adhesion of specific probiotics and their combinations in the intestinal mucus of infants during and after rotavirus diarrhea and in healthy children were determined. Mucus was prepared from fecal samples from 20 infants during and after rotavirus diarrhea and from 10 healthy age-matched children. Mucin concentration was determined, and the adhesion of five probiotics-Lactobacillus rhamnosus GG, Lactobacillus casei Shirota, Lactobacillus paracasei F19, Lactobacillus acidophilus LA5, and Bifidobacterium lactis Bb12-and their combinations was tested in vitro. The mean concentrations of fecal mucin during and after rotavirus diarrhea, 15.2 and 14.1 mg/g, were comparable to that in healthy children, 14.9 mg/g. The adherence of probiotics ranged from 1 to 34% in healthy subjects as indicated for the following strains: L. rhamnosus GG, 34%; B. lactis Bb12, 31%; L. acidophilus LA5, 4%; L. paracasei F19, 3%; and L. casei Shirota, 1% (P = 0.0001). The distinctive pattern of probiotic adherence was not influenced by rotavirus diarrhea. The adhesion of Bb12 in the presence of GG increased from 31 to 39% in healthy infants (P = 0.018) and in episodes of diarrhea increased from 26 to 44% (P = 0.001). Rotavirus diarrhea does not decrease the production of fecal mucin or with respect to the adhesion of probiotic bacteria tested in vitro. Combination of specific probiotic strains may enhance adherence in a synergistic manner. Optimal clinical application of these interactions may offer novel therapeutic guidelines for the treatment and prevention of gastrointestinal infections.
Toxicity and Repellency of Borate-Sucrose Water Baits to Argentine Ants (Hymenoptera: Formicidae) (2000)

The oral toxicity of boron compounds to the Argentine ant, Linepithema humile (Mayr), was evaluated in laboratory tests. The ants were provided 25% sucrose water containing 0.5 and 1% boric acid, disodium octaborate tetrahydrate, and borax. Lethal times of these solutions were a function of the concentration of boron. In field tests, the ants showed no discrimination between disodium octaborate tetrahydrate and boric acid. There was a significant reduction in consumption of sucrose water with > 1% boric acid.
Identification of novel peptides for horse meat speciation in highly processed foodstuffs (2015)

There is a need for robust analytical methods to support enforcement of food labelling legislation. Proteomics is emerging as a complementary methodology to existing tools such as DNA and antibody-based techniques. Here we describe the development of a proteomics strategy for the determination of meat species in highly processed foods. A database of specific peptides for nine relevant animal species was used to enable semi-targeted species determination. This principle was tested for horse meat speciation, and a range of horse-specific peptides were identified as heat stable marker peptides for the detection of low levels of horse meat in mixtures with other species.
Fault Detection and Diagnosis for GTM UAV with Dual Unscented Kalman Filter (2010)

This paper presents an applicable procedure for Fault Detection and Diagnosis (FDD) in a realistic nonlinear six degree-of-freedom unmanned aerial vehicle (UAV) model. The work has been developed based on the Matlab/Simulink environment of the NASA Generic Transport Model (GTM) UAV under the NASA Aviation Safety Program (AvSP). By introducing the partial loss fault in aircraft actuators into the GTM model, the dual Unscented Kalman Filter (UKF) algorithm is implemented for online estimation of both flight states and fault parameters, and for making statistical decisions associated with fault detection and diagnosis.
Structural analysis of the umu operon required for inducible mutagenesis in Escherichia coli. (1985)

The nucleotide sequence of a 2.8-kilobase fragment of the Escherichia coli chromosome containing the umuDC genes has been determined. The DNA sequence specifies two open reading frames of 417 and 1266 nucleotides encoding proteins with calculated molecular weights of 15,063 and 47,677, respectively. From these and the previous results of genetic and biochemical studies on the cloned genes, we conclude that the former is the umuD and the latter is the umuC gene. In vitro transcription of the regulatory region of the umu operon revealed that (i) upstream of the coding region there is a promoter-operator complex having the consensus sequence, CTGTATATAAAAACAG, of an SOS box, (ii) transcription of the umu operon begins at an adenine residue in the SOS box, and (iii) the LexA protein binds to the operator region, with an equilibrium dissociation constant (Kd) of 0.2, thereby repressing the transcription of the umuDC genes. These results indicate that the expression of the umu operon is under the coordinated control of the recA lexA gene products.
Contrast‐Enhanced Two‐ and Three‐dimensional Sonography for Evaluation of Intra‐abdominal Hemorrhage (2002)

Contrast-enhanced sonography improves the detection and evaluation of abdominal bleeding sites. Contrast-enhanced three-dimensional sonography appears to provide additional information when compared with two-dimensional sonography.
The Design and Implementation of a Scheduling Mechanism of Differentiated Services Based on Priority (2009)

A scheduling mechanism of differentiated services based on priority is presented in this paper, which is used to resolve a problem of resource assigned fairly in circumstance of wireless multi-services. This scheduling mechanism contrasts with other multi-services scheduling algorithms in performance by simulation. The simulation results indicate that the scheduling mechanism can provide QoS guarantee and opportunity of sharing fairly bandwidth for different services, and it also gives attention to capacity optimization and fair factor.
Thermomechanical recovery couplings of shape memory polymers in flexure (2003)

Shape memory polymers (SMPs) have the capacity to recover large strains when pre-deformed at an elevated temperature, cooled to a lower temperature and reheated. The thermomechanical recovery behavior of an SMP is examined in three-point flexure for various pre-deformation and recovery conditions. Results indicate that when pre-deformed well above the glass transition temperature, Tg, the stress–strain response at the pre-deformation temperature governs the relationship between the recovery stress/strain and the corresponding pre-deformation strain/stress. When pre-deformed at a temperature below Tg, the relationship between recoverable stress and strain level in the SMP is not governed by the stress–strain response of the material at the pre-deformation temperature. Rather, a peak recovery stress, which is less than the applied pre-deformation stress, appears near Tg. Higher cooling rates during constraint lower the temperature necessary for complete shape fixity, but increase the recoverable stress level. Higher heating rates during recovery raise the recovery onset temperature and decrease the peak recoverable stress. Ramifications of the results on future research efforts and emerging applications of SMPs are discussed.
Automatic collection of powder data from photographs (1975)

A method is presented of determining powder data from photographs. With a microphotometer the density is measured in steps of 0.01° 2θ. These data are used by a computer program. With this program the background and the noise level are determined first. After the detection of the diffraction peaks, the peak positions and intensities are refined, a suitable model for the peak profile being used. A procedure is described for scaling of several photographs. The final results are illustrated with a comparison of 2θ values determined according to this method and the calculated values of the lattice refined with these data. The resulting data prove to be equivalent to the data obtained by conventional means. The computer program is written in FORTRAN IV.
The therapeutic response to D-penicillamine in rheumatoid arthritis: influence of glutathione S-transferase polymorphisms (1999)

Our results suggest that GST polymorphisms may influence the response to D-penicillamine in RA, and that patients in possession of the GSTM1*0/GSTM3*A haplotype are significantly less likely to show a beneficial response to the drug.

Measurement of Multidrug-Resistance Messenger RNA in Urogenital Cancers; Elevated Expression in Renal Cell Carcinoma is Associated with Intrinsic Drug Resistance (1988)

We measured the levels of messenger RNA of the human multidrug-resistance gene (MDR1) in 25 urogenital tumors before chemotherapy. Many of the renal cell carcinomas continued to express MDR1 gene at high levels, reflecting the increased expression of MDR1 RNA in normal kidneys. In other urogenital tumors, the MDR1 RNA levels were low reflecting low MDR1 RNA levels in normal bladder, prostate and testis. For comparative purposes, we performed in vitro chemosensitivity testing on many tumor samples using soft agar culture techniques. Vinblastine sensitivity in vitro inversely correlated with MDR1 RNA levels (p less than 0.01). Moreover, mean sensitivity of seven renal cell carcinomas to vinblastin was significantly lower than that of the other seven cancers (p less than 0.05). As for doxorubicin, mean sensitivity of six renal cell carcinomas was lower than the others (p less than 0.1). These results suggest that the high MDR1 RNA levels in renal cell carcinomas are associated with intrinsic multidrug-resistance.
Comparison of copper interconnect electromigration behaviors in various structures for advanced BEOL technology (2004)

Copper interconnect electromigration (EM) performance was examined in three low-k materials (k=2.65/spl sim/3.6) using advanced back end of line (BEOL) technology. Comparable time to failure distributions were achieved after process optimization for each material. The Ea and n ranged from 0.8 eV to 0.9 eV and 1.1 to 1.4, respectively, and agree well with the interface diffusion mechanism and void nucleation mechanism. Various testing structures were designed to identify the EM failure modes. Extensive failure analysis was carried out to understand the failure phenomena of various test structures. Results of the present study suggest that the interface of Cu interconnects is the key factor for EM lifetime performance for advanced BEOL technology design rules. The weak links of the interconnect system were also identified.
Coupled semi-supervised learning for information extraction (2010)

We consider the problem of semi-supervised learning to extract categories (e.g., academic fields, athletes) and relations (e.g., PlaysSport(athlete, sport)) from web pages, starting with a handful of labeled training examples of each category or relation, plus hundreds of millions of unlabeled web documents. Semi-supervised training using only a few labeled examples is typically unreliable because the learning task is underconstrained. This paper pursues the thesis that much greater accuracy can be achieved by further constraining the learning task, by coupling the semi-supervised training of many extractors for different categories and relations. We characterize several ways in which the training of category and relation extractors can be coupled, and present experimental results demonstrating significantly improved accuracy as a result.

3D Reconstruction using Airbone Velodyne Laser Scanner (2013)

The 3D reconstruction of the terrain by airbone LRF (Laser Range Finder) requires the 3D motion of sensor, however the payload of small airbone platforms, such as radio control models, are highly restricted, and precise inertial motion units are too heavy to be mounted on it. The HDL32E, an LRF recently provided by Velodyne, is light enough to be installed to the airbone vehicle such as a blimp, and has 32 rays for scanning so that it can sense wide range of terrain at one scan cycle which means low dense 3D pointcloud are collected at very short time. This paper proposes the fast and simple method for integrating those low dense pointclouds to high dense pointcloud without any intertial motion sensor. The method uses equal or more than 3 planes not parallel on the terrain, and estimates LRF's 3D motion. The final integration result will be shown after the optimization of laser scanner's motion.
Fabrication and evaluation of Dihedral Corner Reflector Array for floating image manufactured by synchrotron radiation (2015)

We propose a new imaging optics called Dihedral Corner Reflector Array (DCRA) which is designed to make the floating image. DCRA consists of numerous micro-mirrors placed perpendicular to the surface of substrate. The micro-mirror array is implemented by the inner walls of minute square holes or the side of minute square pillar. We can choose two types of the structure. The primordial is based on two reflections by a pair of adjacent mutually perpendicular mirrors, i.e., a dihedral corner reflector. Although the principal of operation is based on reflection by mirrors, the device is also transmissive and deflects light. Primordial of DCRA is not so complicated, However, it is too difficult to fabricate the DCRA by usual machining because of high aspect ratio micromachining and high mirror accuracy. Therefore, in this manuscript, we fabricated the device by deep X-ray lithography due to synchrotron radiation. The characteristics of the fabricated DCRA are evaluated by the optical transmission and reflection measurements.
Genomic evidence that the intracellular proteins of archaeal microbes contain disulfide bonds (2002)

Disulfide bonds have only rarely been found in intracellular proteins. That pattern is consistent with the chemically reducing environment inside the cells of well-studied organisms. However, recent experiments and new calculations based on genomic data of archaea provide striking contradictions to this pattern. Our results indicate that the intracellular proteins of certain hyperthermophilic archaea, especially the crenarchaea Pyrobaculum aerophilum and Aeropyrum pernix, are rich in disulfide bonds. This finding implicates disulfide bonding in stabilizing many thermostable proteins and points to novel chemical environments inside these microbes. These unexpected results illustrate the wealth of biochemical insights available from the growing reservoir of genomic data.
Pancake shaped micro gear system with high transmission ratio (2000)

Within the last five years micro motors with dimensions in the millimeter range have been established for a large variety of applications. Usually, a gear is necessary to adapt the motor to the users requirements. Suitable gears for micro motors of the longish type are already commercially available. On the other hand there are applications which need very flat actuators. For these cases we recently have realized a penny shaped electromagnetic motor as thin as 1.4 mm. To enable the adaptation of the penny motor to a variety of applications, a micro gear system was developed which should be introduced in this contribution. The pancake shaped gear system measures 8 mm in diameter and only 1 mm in height. The working principle of this ultra flat micro gear system is called Harmonic Drive: a flexible gear ring interferes with internal gears. By using LIGA technology a ring thickness of only 40 2m was achieved corresponding to an aspect ratio of 25 : 1. The deformation of the flexible gear is generated by planetary gears which enables a high gear ratio. By now, a prototype made of NiFe has been built. For mass- production, the gear wheels would be fabricated of plastics by micro injection molding. There are three variants of this pancake shaped micro gear with gear ratios of 100 : 1, 500 : 1 and 1032 : 1 respectively. A maximum output torque of up to 15 mNm and a efficiency of up to 40 % was measured. The output torque fits ideally to the penny shaped motor, which delivers a motor torque of 80 2Nm. Additionally, input speeds of up to 50,000 rpm are possible for the gear. As another advantage, this pancake shaped micro gear runs without backlash caused by a special design of the planetary gear wheels. Therefore, the miniaturized gear system is suitable for high precision positioning mechanisms. Applications for this gear system could be rotary tables for mirrors or the use in complex micro robots, for example.
An Efficient Parallel Algorithm for the General Planar Monotone CircuitValue Problem (1993)

. A planar monotone circuit (PMC) is a Boolean circuit that can be embedded in the plane and that contains only AND and OR gates. Goldschlager, Cook &amp; Dymond and others have developed NC 2 algorithms to evaluate a special layered form of a PMC. These algorithms require a large number of processors(\\Omega\\Gamma n 6 ), where n is the size of the input circuit). Yang, and more recently, Delcher &amp; Kosaraju have given NC algorithms for the general planar monotone circuit value problem. These algorithms use at least as many processors as the algorithms for the layered case. This paper gives an efficient parallel algorithm that evaluates a general PMC of size n in polylog time using only a linear number of processors on an EREW PRAM. This parallel algorithm is the best possible to within a polylog factor, and is a substantial improvement over the earlier algorithms for the problem. The algorithm uses several novel techniques to perform the evaluation, including the use of the dual of the...
Improving Function Allocation for Integrated Systems Design (1996)

This book is a compilation of the 17 papers presented during the November 1994 workshop on Function Allocation at the TNO Human Factors Research Institute, Soesterberg, The Netherlands. The workshop was sponsored by the Research Study Group 14 (RSG 14) of NATO Defense Research Group Panel 8, which in an earlier review of human engineering analysis techniques, had concluded that function allocation was the weakest of the techniques reviewed. The present workshop identified and examined central issues and techniques in function allocation (e.g., two-stage and iterative function allocation processes, reverse engineering, flexible allocation, and adaptive allocation), discussed methods for evaluating function allocation decisions, and described state-of-the-art applications of function allocation techniques.
A location management protocol for hierarchically organized multihop mobile wireless networks (2002)

We consider the problem of location management in a large, hierarchically organized multihop mobile network, where the switches comprising the infrastructure as well as the endpoints (terminals) may be mobile. Such networks are common in applications such as battlefield networks, disaster management, law enforcement, etc. We present a novel network architecture and location management protocol that accommodates switch mobility and, using a new concept called "roaming level", allows the updating procedure to be controlled on a per endpoint basis. We discuss simulation results on the variation of performance with the speed, roaming level and call frequency of endpoints. Our results show that at high endpoint speeds or low call frequencies a significant decrease in the control overhead can be obtained in comparison to traditional schemes.
Reaction of (μ-H)<sub>2</sub>Os<sub>3</sub>(CO)<sub>9</sub>(PPh<sub>3</sub>) with Acetylene and Ethylene. Structures, Dynamics, and Interconversion of Two Isomers of the Vinyl Complex (μ-H)Os<sub>3</sub>(CO)<sub>9</sub>(PPh<sub>3</sub>)(μ-CHCH<sub>2</sub>) (1996)

As reported previously by Brown and Evans, the reaction of (μ-H)2Os3(CO)9(PPh3) with acetylene provides two isomers of the hydrido vinyl compound (μ-H)Os3(CO)9(PPh3)(μ-η2-CHCH2) (2). The solid-state structures of these two isomers now have been defined by single-crystal X-ray crystallography. The major isomer 2a contains a triangular array of osmium atoms with the vinyl ligand bridging the Os(2)−Os(3) edge, forming a σ-bond to Os(3) and a π-bond to Os(2), and the triphenylphosphine ligand coordinating to Os(2) in an “in-plane” position. The presence of the hydride ligand also bridging the Os(2)−Os(3) edge was deduced indirectly. The minor isomer 2b also contains a triangular Os3 array with the vinyl ligand bridging the Os(2)−Os(3) edge and forming a σ-bond to Os(2) and a π-bond to Os(3). The triphenylphosphine ligand is bound to Os(1). The presence of the bridging hydride on the Os(1)−Os(3) edge was not directly detected but was supported by analysis of the structure; the hydride ligand therefore does not bridge the same edge as the vinyl moiety. The solution structures and dynamics of 2a and 2b have been investigated by variable-temperature 13C NMR and 13C spin saturation transfer experiments; isomer 2a exhibits evidence for nondegenerate σ/π bond interchange in the bridging vinyl group. Separation of 2a and 2b can be effected by thin-layer chromatography (silica; CH2Cl2/C6H14, 1:3); subsequent 1H NMR spectra reveal slow equilibration of 2a and 2b (t1/2 = 85 min, 2a:2b = 2.2:1 at equilibrium). The same mixture of isomers is formed from the reaction of 1 with ethylene at high pressure (500 psig), with the previously characterized complex (μ-H)2Os3(CO)9(PPh3)(μ-CHCH3) as an intermediate.
