An Enzyme-Linked Immunosorbent Assay for Detection of Antibodies against Escherichia coli: Association between Indirect Hemagglutination Test and Survival (1990)

An enzyme-linked immunosorbent assay (ELISA) was modified for detection of antibodies against the two main pathogenic serotypes of Escherichia coli: serotypes O78:K80 and O2:K1. The ELISA was a more sensitive and repeatable test than the indirect hemagglutination test (IHT), which is a common method for detecting antibodies against E. coli. Cross-reactivity between the two strains was measured by reacting antisera of each serotype against homologous and heterologous antigens. The results suggest that aside from similar determinants expressed by the two serotypes, serotype O2:K1 expresses more strain-specific determinants than does O78:K80. Comparison of mean antibody titers of immunized chicks by IHT and ELISA along the primary response revealed that during the first 15 days after immunization with inactivated E. coli, the titers in both tests were parallel. After 15 days post-immunization, antibody titers measured by IHT decreased rapidly, whereas titers measured by ELISA decreased only slightly. In addition, a higher correlation was found between titers detected by ELISA and survival through challenge with E. coli than between titers detected with IHT and survival through challenge. The results suggest that the ELISA is a better test for detection of antibody in flocks suspected of being infected with E. coli.
Differential expression of oocyte-type class III genes with fraction TFIIIC from immature or mature oocytes. (1992)

The Xenopus OAX genes can be expressed in oocytes but are virtually inactive in somatic tissues. The tRNA(Met1) (tMET) genes also appear to be developmentally regulated. We have examined the reason for the differential expression of these class III genes. Analysis of the transcriptional activities of extracts derived from immature and mature oocytes revealed that the developmental regulation of these genes can be reproduced in vitro. We have partially purified the required transcription factors B and C from these extracts to ascertain the components responsible for this differential activity. The immature oocyte C fraction activates the tMET and OAX genes when reconstituted with either the immature or mature oocyte-derived B fraction. In contrast, the mature oocyte C fraction fails to activate these genes regardless of which B fraction is used. Both C fractions activated the somatic 5S gene. Purification of the oocyte C fractions by phosphocellulose or B box DNA affinity chromatography failed to separate additional activities responsible for the differential expression of OAX or tMET. By using template exclusion assays, the inability of the mature oocyte C fraction to activate transcription was correlated with an inability to form stable transcription complexes with the tMET or OAX gene.
Preventing Mesh Pore Collapse by Designing Mesh Pores With Auxetic Geometries: A Comprehensive Evaluation Via Computational Modeling (2018)

Pelvic organ prolapse (POP) meshes are exposed to predominately tensile loading conditions in vivo that can lead to pore collapse by 70-90%, decreasing overall porosity and providing a plausible mechanism for the contraction/shrinkage of mesh observed following implantation. To prevent pore collapse, we proposed to design synthetic meshes with a macrostructure that results in auxetic behavior, the pores expand laterally, instead of contracting when loaded. Such behavior can be achieved with a range of auxetic structures/geometries. This study utilized finite element analysis (FEA) to assess the behavior of mesh models with eight auxetic pore geometries subjected to uniaxial loading to evaluate their potential to allow for pore expansion while simultaneously providing resistance to tensile loading. Overall, substituting auxetic geometries for standard pore geometries yielded more pore expansion, but often at the expense of increased model elongation, with two of the eight auxetics not able to maintain pore expansion at higher levels of tension. Meshes with stable pore geometries that remain open with loading will afford the ingrowth of host tissue into the pores and improved integration of the mesh. Given the demonstrated ability of auxetic geometries to allow for pore size maintenance (and pore expansion), auxetically designed meshes have the potential to significantly impact surgical outcomes and decrease the likelihood of major mesh-related complications.
The Benefit of Chilling in Argon-Laser Treatment of Port-Wine Stains (1985)

The authors compare results obtained in argon laser treatment of port-wine stains with and without preliminary chilling, noting that the success rate is considerably greater with the former procedure (68.6 percent) than with the latter (37.5 percent) (X2 = 4.37 p less than 0.05). The effect of chilling has been studied with special reference to the vitropressure test. Different hypotheses are presented to account for the difference and possible complications of the treatment are considered.
A Mixed Classification-Regression Framework for 3D Pose Estimation from 2D Images (2018)

3D pose estimation from a single 2D image is an important and challenging task in computer vision with applications in autonomous driving, robot manipulation and augmented reality. Since 3D pose is a continuous quantity, a natural formulation for this task is to solve a pose regression problem. However, since pose regression methods return a single estimate of the pose, they have difficulties handling multimodal pose distributions (e.g. in the case of symmetric objects). An alternative formulation, which can capture multimodal pose distributions, is to discretize the pose space into bins and solve a pose classification problem. However, pose classification methods can give large pose estimation errors depending on the coarseness of the discretization. In this paper, we propose a mixed classification-regression framework that uses a classification network to produce a discrete multimodal pose estimate and a regression network to produce a continuous refinement of the discrete estimate. The proposed framework can accommodate different architectures and loss functions, leading to multiple classification-regression models, some of which achieve state-of-the-art performance on the challenging Pascal3D+ dataset.
Microbial Community Response to Simulated Petroleum Seepage in Caspian Sea Sediments (2017)

Anaerobic microbial hydrocarbon degradation is a major biogeochemical process at marine seeps. Here we studied the response of the microbial community to petroleum seepage simulated for 190 days in a sediment core from the Caspian Sea using a sediment-oil-flow-through (SOFT) system. Untreated (without simulated petroleum seepage) and SOFT sediment microbial communities shared 43% bacterial genus-level 16S rRNA-based operational taxonomic units (OTU<sub>0.945</sub>) but shared only 23% archaeal OTU<sub>0.945</sub>. The community differed significantly between sediment layers. The detection of fourfold higher deltaproteobacterial cell numbers in SOFT than in untreated sediment at depths characterized by highest sulfate reduction rates and strongest decrease of gaseous and mid-chain alkane concentrations indicated a specific response of hydrocarbon-degrading Deltaproteobacteria. Based on an increase in specific CARD-FISH cell numbers, we suggest the following groups of sulfate-reducing bacteria to be likely responsible for the observed decrease in aliphatic and aromatic hydrocarbon concentration in SOFT sediments: clade SCA1 for propane and butane degradation, clade LCA2 for mid- to long-chain alkane degradation, clade Cyhx for cycloalkanes, pentane and hexane degradation, and relatives of <i>Desulfobacula</i> for toluene degradation. Highest numbers of archaea of the genus <i>Methanosarcina</i> were found in the methanogenic zone of the SOFT core where we detected preferential degradation of long-chain hydrocarbons. Sequencing of <i>masD</i>, a marker gene for alkane degradation encoding (1-methylalkyl)succinate synthase, revealed a low diversity in SOFT sediment with two abundant species-level MasD OTU<sub>0.96</sub>.
A Computer Technique for Analyzing Pumping Well Performance (1968)

Abstract A computerized analytical technique for investigating sucker rod pumping well performance develops load-position values (dynagraphs) at the pump, at desired points in the rod string and at the polished rod through use of a mathematical model of the sucker rod installation. Using the load-position diagrams of the pump, junction points and polished rod, quantitative deductions may be made regarding the mechanical condition and performance of the down-hole equipment (rod string, pump, tubing anchor, etc.) and the physical properties of the well itself (pump submergence, gas interference, fluid pound, etc.). Analysis of subsurface dynagraphs from several cave histories is discussed. Introduction Production men have recognized for years that a more complete knowledge of rod pumping performance would suggest means of lowering lifting costs, making more appropriate installation designs and increasing the proportion of oil economically recoverable by rod pumping. It was this need for knowledge that led to intensive studies from 1927 to 1943. During those years the polished rod dynamometer (1927), the bottom-hole pressure bomb (1929), the pump dynagraph (1936) and the sonic fluid-level sounder (1936) were developed. During that time many engineers used those tools to develop the theories on which our present knowledge of sucker rod pumping is based. Contributions made since 1943, in an effort to correlate data obtained from the various instruments, are mostly elaborations and refinements of the basic principles established during the preceding period. A notable exception is the Gibbs-Neely mathematical technique that analyzes pumping well performance with a digital computer. In effect, the technique yields all the information derived from these mechanical devices but has the added advantage of requiring only one series of measurements taken and recorded at the polished rod.
Cloud Template, a Big Data Solution (2013)

Today cloud computing has become as a new concept for hosting and delivering different services over the Internet for big data solutions. Cloud computing is attractive to different business owners of both small and enterprise as it eliminates the requirement for users to plan ahead for provisioning, and allows enterprises to start from the small and increase resources only when there is a rise in service demand. Despite the fact that cloud computing offers huge opportunities to the IT industry, the development of cloud computing technology is currently has several issues. This study presents an idea for introducing cloud templates which will be used for analyzing, designing, developing and implementing cloud computing systems. We will present a template based design for cloud computing systems, highlighting its key concepts, architectural principles and state of the art implementation, as well as research challenges and future work requirements. The aim of this idea is to provide a better understanding of the design challenges of cloud computing and identify important research directions in this big data increasingly important area. We will describe a series of studies by which we and other researchers have assessed the effectiveness of these techniques in practical situations. Finally, in this study we will show how this idea could be implemented in a practical and useful way in industry.
DESIGN OF A MODERATOR ASSEMBLY DELIMITER FOR AN ABNS FOR BNCT (2005)

As part of an effort to design a moderator assembly for an Accelerator Based Neutron Source (ABNS) for Boron Neutron Capture Therapy (BNCT), we have implemented a modified version of the Zubal Phantom (a voxel-based head phantom that delineates detailed structures inside the brain) in MCNP. As the component of the moderator assembly that is closest to the patient, the shape and material of the delimiter is important to the quality of the neutron beam. Using our Zubal Phantom MCNP model, we have evaluated various moderator assembly delimiter designs. The evaluation was based on the calculation of a new neutron field assessment parameter (NFAP) that we developed to evaluate the complex dose distributions resulting from the mixed neutron and gamma-ray fields that arise in the head of an individual who is treated for a malignant brain tumor using BNCT. The modified Zubal phantom was used to calculate the absorbed doses of different structures in the brain as well as the tumor dose. The new NFAP is based on absorbed dose distributions for normal tissues/structures and tumor, and yields a score that accounts for the competing goals of sparing normal tissues and maximizing tumor dose. It was formulated by modifying a previously defined Objective Function, so that it is appropriate for BNCT. The resulting BNCT Objective Function (BOF) allows for the inclusion of tissue specific Relative Biological Effectiveness (RBE), and tissue specific dose tolerances and weights. In addition to assessing the effect of the delimiter on the BOF, the effect of the delimiter in reducing the whole body dose to the bone marrow was assessed using MCNP with a MIRD whole body phantom.
Structural Analysis of Curly Human Hair Single Fibers by Scanning Microbeam SAXS (2006)

Understanding the cause of hair curliness is one of major isuues in the cosmetics field. We studied the nanostructure of curly hair fibers, and detected the lateral inhomogeneity of the arrangement of the intermediate filaments (IFs) in the cortex, which was associated with the fiber curvature [1]. In this study, the correlation between the macroscopic curliness and the microscopic inhomogeneity of hair fibers of different curliness among three major ethnic groups has been investigated in detail.
Guaranteeing 2-manifold property for meshes (1999)

Meshes are the most commonly used objects in computer graphics. They generalize polyhedra by using non-planar faces. Modeling 2D manifold meshes with a simple user interface is an important problem in computer-aided geometric design. In this paper, we propose a conceptual framework for mesh modeling systems that guarantees topologically correct 2D manifolds. Our solution is based on graph rotation systems developed in topological graph theory. As an internal representation of meshes, we use a doubly-linked face list (DLFL). We have also developed a visual representation of the topology that provides a powerful tool for developing a user interface to manipulate the topology of the mesh.
A Force‐Feedback Exoskeleton for Upper‐Limb Rehabilitation in Virtual Reality (2009)

This paper presents the design and the clinical validation of an upper‐limb force‐feedback exoskeleton, the L‐EXOS, for robotic‐assisted rehabilitation in virtual reality (VR). The L‐EXOS is a five degrees of freedom exoskeleton with a wearable structure and anthropomorphic workspace that can cover the full range of motion of human arm. A specific VR application focused on the reaching task was developed and evaluated on a group of eight post‐stroke patients, to assess the efficacy of the system for the rehabilitation of upper limb. The evaluation showed a significant reduction of the performance error in the reaching task (paired t ‐test, p < 0.02)
A Dual-Polarized Cross-Slot Antenna Array on a Parallel-Plate Waveguide With Compact Structure and High Efficiency (2017)

A dual-polarized cross-slot antenna array based on the parallel-plate waveguide (PPW) is presented in this letter. A new compact 2 × 2-element subarray consisting of four radiating cross-slots, four out cavities, one coupling cross-slot, and one metallic-block-loaded resonant cavity is first proposed to achieve dual polarization and high efficiency. Two orthogonally arranged H-plane waveguide feed networks combined with the low-loss PPW are used to generate a pair of orthogonal plane waves to feed the subarray. To demonstrate the merits of the antenna, an 8 × 8 array prototype is designed and fabricated. The measured result shows that the aperture efficiency exceeding 60% is obtained throughout the band of 12-12.6 GHz. The isolation between two polarizations is higher than 25 dB over the bandwidth. Therefore, this antenna array can be a good alternative for satellite communications systems in airborne applications.
Low-noise antiferromagnetically coupled media through the use of a superparamagnetic CoCrRu intermediate layer (2003)

A superparamagnetic CoCrRu alloy is proposed for the intermediate layer (IL) between Ru/M2 in a typical antiferromagnetically coupled media structure M1/Ru/M2 (M2: recording layer). With the presence of the IL, the exchange coupling energy (Jex) initially increases from ∼0.09 to ∼0.10 erg/cm2 and asymptotes to ∼0.056 erg/cm2 when the IL thickness reaches 11 A. Due to its superparamagnetic nature, the CoCrRu IL does not introduce extra medium noise, in contrast to the ferromagnetic CoCrPtTa IL. The vibrating sample magnetometer thermal stability ratio (KV/kT) increases from 52 to 58 with a ∼7 Å CoCrRu IL, in agreement with the improved spin stand signal decay. X-ray diffraction scans indicate an improved epitaxial growth in the M2 layer when a CoCrRu IL is present.
Expression of shared idiotypes by paraproteins from patients with monoclonal gammopathy of undetermined significance (1994)

We have previously demonstrated the expression of shared idiotypes by the paraproteins from approximately one-quarter of patients with multiple myeloma (MM). We have now investigated whether similar cross-reactivity is expressed in the paraproteins of patients with monoclonal gammopathy of undetermined significance (MGUS), using a panel of 32 monoclonal antibodies (MAB) generated against follicular B cell lymphomas. The paraproteins from 76/409 (19%) patients with MGUS reacted with at least one of 23 different anti-idiotypic antibodies used in this study. 18 MABs demonstrated reactivity with more than one patient's paraprotein. Moreover, 10 MABs reacted frequently (with 5-22 paraproteins). Over half (41/76) of the reactive patients' paraproteins reacted with more than one MAB from this panel. This frequency of anti-idiotypic reactivity was similar to that of previously studied patients with myeloma, chronic lymphocytic leukaemia (CLL), and follicular B-cell lymphomas. There was no correlation between specific anti-idiotypic reactivity and the propensity to develop serious disease (MM, macroglobulinaemia, amyloidosis, or other lymphoproliferative disorders) in patients with MGUS. These results suggest that MGUS is derived from cells producing antibodies that are similar to those of other B-cell malignancies and that the pattern of idiotype expression is irrelevant to malignant potential.
Improving Throughput for Grid Applications with Network Logistics (2005)

This work describes a technique for improving network performance in Grid environments that we refer to as "logistics." We demonstrate that by using storage and cooperative forwarding "in" the network, we can improve end to end throughput in many cases. Our approach uses TCP connections in series and offers performance benefits for high-bandwidth, high-latency networks. First, we examine the underlying causes of the logistical effect. Next, we present a graph based scheduling approach that can be solved quickly and, within our assumptions, optimally. Finally, we present a large-scale empirical evaluation of the system in order to validate our scheduling approach for taking advantage of network logistics. This study demonstrates performance improvement in many situations and aggregate speedup results are presented.
Magnetic characteristics of ultrafine Fe particles reduced from uniform iron oxide particles (1987)

Uniform, cubic 0.05-μm iron oxide particles were formed by forced hydrolysis of ferric perchlorate. These particles were reduced to α-Fe by heating in hydrogen at temperatures between 300 and 500 °C. The effect of reduction temperature and various prereduction treatments on the microstructure of the iron particles will be discussed. Complete reduction to α-Fe was established by 57Fe Mössbauer spectroscopy and x-ray diffraction. Magnetic measurements on epoxy and polyurethane films containing these particles with various mass fractions gave coercivities as high as 1000 Oe. The relationship between the magnetic measurements and the microstructure will be discussed. Na2SiO3 is found to be the best coating material for the process of reducing iron oxide particles to iron.

Implementing and Evaluating a Smart-M3 Platform-based Multi-vendor Micropayment System Pilot in the Context of Small Business. (2014)

Today, micropayment systems usage is highly topical. For example, applications of mobile micropayment systems are widely used and are well known by the public.The objective of this study was to implement a micropayment system pilot based on an interoperability enabling platform (in this case, Smart-M3) for small businesses with restricted resources, scarce labor force, and a growing number of products and vendors.In these small and medium-sized enterprise (SME) contexts, piloting systems of this kind is usually problematic because of its immediate impact on the core business and monetary transactions that are essential for SMEs. An account-based system was considered an appropriate starting point for the micropayment system pilot. The applicability of the Smart-M3 platform was then validated by the implementation of the system. Lastly, a summative evaluation was carried out by interviewing direct stakeholders, to enrich the observations from the validation. The results of the study show that the implemented system provides small businesses with opportunities to reduce costs and more efficiently use resources, adding new devices and systems, new ways to produce services, andreal-time tracking of the sales process, as well as utilization of the data collected from the system. From the customers’ point of view, the efficient use of resources may lead to more competitive prices of the products and services. Micropayment system usage can also be seen as a starting point for improved user experience, includingsafety, efficiency, and ease of use.
