Initial supersonic combustion facility measurements (1989)

A combustion test tunnel designed for continuous operation to 2000 K was assembled. Flow quality of a Mach 2 nozzle for use with this tunnel was examined using an array of impact probes. The performance of gas shields used to protect optical windows was examined using both shadowgraphs and planar laser induced iodine fluorescence. High speed videography was used to aid in design of pressure relief panels related to hydrogen combustion testing safety.
On the two-dimensionality of the critical disturbances for stratified viscous plane parallel shear flows (1985)

It is rigorously proved that the most critical small disturbances to a stratified viscous plane parallel shear flow between rigid horizontal boundaries must be either two-dimensional (2-D) transverse or longitudinal modes, and that there are no marginally stable flows for which truly 3-D disturbances are marginally stable. This allows the linear stability analysis to be restricted to (two classes of ) 2-D disturbances.
Application of engineering analysis techniques to the design of magnetic resonance imaging (MRI) coils (2008)

In this paper, we develop a new approach to analysing and designing the gradient coils for magnetic resonance imaging (MRI) scanners for medical applications. More specifically, a novel higher-order BEM which satisfies the continuity equation for the current density is proposed. We also present solution procedures for applying this method to the inverse problem whereby the divergence-free surface current distribution in the gradient coil is deduced from knowledge of the magnetic flux density in a prescribed region of interest. The novel BEM proposed is a non-traditional one, in the sense that the collocation points are given by the vertices of the triangular elements only and not all the BEM nodes used to define the boundary elements. Furthermore, the degree of the interpolation is one degree less than that of the geometry of the triangular elements employed, so that (for example) the linear boundary elements involve constant interpolation for the surface current density. Moreover, the present method can be easily extended in order to obtain any desired degree of the interpolation for the surface current density. Within the inverse problem, care must be taken to employ the optimal value of the Tikhonov regularisation parameter. Results are presented relating to various geometries of coil, obtained using linear, quadratic and cubic variants of the boundary element formulation; those obtained using the quadratic and cubic elements agree almost precisely, while those from the linear elements exhibit small differences from those of the higher-order formulations.

From Federated to Fog Learning: Distributed Machine Learning over Heterogeneous Wireless Networks (2020)

Machine learning (ML) tasks are becoming ubiquitous in today's network applications. Federated learning has emerged recently as a technique for training ML models at the network edge by leveraging processing capabilities across the nodes that collect the data. There are several challenges with employing conventional federated learning in contemporary networks, due to the significant heterogeneity in compute and communication capabilities that exist across devices. To address this, we advocate a new learning paradigm called fog learning, which will intelligently distribute ML model training across the continuum of nodes from edge devices to cloud servers. Fog learning enhances federated learning along three major dimensions: network, heterogeneity, and proximity. It considers a multi-layer hybrid learning framework consisting of heterogeneous devices with various proximities. It accounts for the topology structures of the local networks among the heterogeneous nodes at each network layer, orchestrating them for collaborative/cooperative learning through device-to-device communications. This migrates from star network topologies used for parameter transfers in federated learning to more distributed topologies at scale. We discuss several open research directions toward realizing fog learning.
Optimal Control for the Fuser System of Electro-Photographic Printer (2015)

In this paper, a linear quadratic Gaussian controller is proposed to achieve the robust temperature stability of the fuser system against measurement noise and system disturbance. The proposed controller is fitted to replace the PI controller and relative mathematical derivation is described. The system is implemented using MATLAB and SIMULINK with adding the noise and disturbance. Improvement of performance is verified by comparison with conventional PI controller results on several key factors of the fuser system.
Mapping non-laminar proton acceleration in laser-driven target normal sheath field (2021)

Abstract We report on experimental observation of non-laminar proton acceleration modulated by a strong magnetic field in laser irradiating micrometer aluminum targets. The results illustrate the coexistence of ring-like and filamentation structures. We implement the knife edge method into the radiochromic film detector to map the accelerated beams, measuring a source size of 30–110 μm for protons of more than 5 MeV. The diagnosis reveals that the ring-like profile originates from low-energy protons far off the axis whereas the filamentation is from the near-axis high-energy protons, exhibiting non-laminar features. Particle-in-cell simulations reproduced the experimental results, showing that the short-term magnetic turbulence via Weibel instability and the long-term quasi-static annular magnetic field by the streaming electric current account for the measured beam profile. Our work provides direct mapping of laser-driven proton sources in the space-energy domain and reveals the non-laminar beam evolution at featured time scales.
Cryogenic fracture toughness and temperature rise of thick section weldments in forged JJ1 type austenitic stainless steel plate (1998)

Summary JJ1 type austenitic stainless steel is emerging as the preferred structural material for nuclear fusion reactor superconducting magnet casings designed to operate at the temperature of liquid helium (4 K). To evaluate the cryogenic fracture toughness and temperature rise of tungsten inert gas (TIG) welds in 200 mm thick forged JJ1 type austenitic stainless steel plate for the next generation of nuclear fusion reactor superconducting magnets, clastic-plastic fracture toughness (J1C) tests were conducted with 1T compact tension specimens at 4 K. The tests were conducted to ASTM E813–87 standard specifications for determination of J1C by the unloading compliance technique to monitor crack growth. Au/0.07%Fe-chromel thermocouples were used to measure the temperature rise near the crack tip. The effects of the specimen sampling position and nitrogen content on J1C are examined. Specimens were examined by scanning electron microscopy (SEM) after fracture testing. The effect of the inclusion content on the elastic-plastic fracture toughness parameters (JQ, J1C) as determined by optical microscopy and energy dispersive X-ray spectrometry (EDX) is also discussed.
Synergistic TLR2/6 and TLR9 Activation Protects Mice against Lethal Influenza Pneumonia (2012)

Lower respiratory tract infections caused by influenza A continue to exact unacceptable worldwide mortality, and recent epidemics have emphasized the importance of preventative and containment strategies. We have previously reported that induction of the lungs' intrinsic defenses by aerosolized treatments can protect mice against otherwise lethal challenges with influenza A virus. More recently, we identified a combination of Toll like receptor (TLR) agonists that can be aerosolized to protect mice against bacterial pneumonia. Here, we tested whether this combination of synthetic TLR agonists could enhance the survival of mice infected with influenza A/HK/8/68 (H3N2) or A/California/04/2009 (H1N1) influenza A viruses. We report that the TLR treatment enhanced survival whether given before or after the infectious challenge, and that protection tended to correlate with reductions in viral titer 4 d after infection. Surprisingly, protection was not associated with induction of interferon gene expression. Together, these studies suggest that synergistic TLR interactions can protect against influenza virus infections by mechanisms that may provide the basis for novel therapeutics.
Design space exploration for aggressive core replication schemes in CMPs (2011)

Chip multiprocessors (CMPs) are the dominating architectures nowadays. There is a big variety of designs in current CMPs, with different number of cores and memory subsystems. This is because they are used in a wide spectrum of domains, each of them with their own design goals. This pa per studies different chip configurations in terms of number of cores, size of the shared L3 cache and off-chip bandwidth requirements in order to find what is the most efficient design for High Performance Computing applications. Results show that CMP schemes that reduce the shared L3 cache in order to make room for additional cores achieve speedups of up to 3.31x against a baseline architecture.

Preparation, Characterization, and Synthetic Uses of Lanthanide(III) Catalysts Supported on Ion Exchange Resins (1997)

Lanthanide(III) catalysts supported on ion exchange resins (Ln-resins) were prepared from Dowex, Amberlite, Amberlyst, and other cation exchange resins. The amount of lanthanides on resin supports was measured through EDTA titration. The results indicated that the lanthanides in aqueous solution exchanged with almost all the cations (H+ or Na+) on the resins to form stable ionic complexes between the lanthanides(III) and the resins. The effects of resin types, resin sizes, and lanthanide salts were investigated with a reaction of indole and hexanal in aqueous solution and with an aldol reaction of benzaldehyde and silyl enol ether in organic solvents. The study found that among ion exchange resins tested Amberlyst XN-1010 and Amberlyst 15 complexed with lanthanides(III) were the most effective catalysts. In addition, the selective Ln-resins were utilized to catalyze acetalization of aldehydes, aldol reaction of formaldehyde or benzaldehyde in aqueous solution, nucleophilic addition to an imine, allylation of an aldehyde, an aza Diels−Alder (DA) reaction, and a ring-opening reaction of an epoxide. Furthermore, glycosylation of alcohol using glucosyl fluoride as a donor was also promoted with the Ln-resin. Thus, this work demonstrated potential uses of lanthanide(III) catalysts supported on ion exchange resins in routine organic reactions.
<title>Fiber optic smart bearing load structure</title> (1999)

As proliferation of structures incorporating composite materials occurs, the benefits of in-situ monitoring of the building materials in order to increase reliability and improve maintainability of the overall structure are being recognized. For example, measurement of shear-strain and load within bridge bearings can be directly related to the health and longevity of the structure. In this paper, the embedding of single and multi-axis optical fiber strain sensors within liquid molded load cells for structures such as bridges is reported. Fabrication and testing processes are presented, as well as test results.
Enzyme-linked immunosorbent assays based on polyclonal and monoclonal antibodies for rotavirus detection (1984)

We describe two enzyme-linked immunosorbent assays for rotavirus antigen in feces, which were designed to be as sensitive and specific as possible, and easy to use anywhere. Both are indirect methods, using the antibody capture method, but the second assay utilizes a rotavirus group-specific monoclonal "detecting" antibody instead of the hyperimmune polyvalent guinea pig antisera used in the first assay. Both tests were found to be more sensitive than electron microscopy for detecting virus. To develop these tests, solid phase, antiserum production methods, treatment of the test antigen with EDTA, substrate, stability of reagents, and the need for confirmatory "blocking" tests were all examined. The first assay described is that used at present by the World Health Organization for their worldwide diarrheal disease control program.
Oncornavirus‐like particles in HeLa cells. II. Immunological characterization of the virus (1974)

Abstract An oncornavirus‐like agent has been described in HeLa cells of human origin (Gelderblom et al. , 1974). The investigation of its protein constituents revealed a pattern similar to but different from that of known oncornaviruses. Six polypeptides with molecular weights (mw) between 12,000 d and 28,000 d, and two glycopolypeptides of about 60,000 d and 80,000 d mw were detected by SDS‐polyacrylamide gel electrophoresis. No serological cross‐reaction was found between the HeLa virus and B‐ and C‐type oncornaviruses. Essentially, none of two interspecies‐specific antigenic determinants described in mammalian C‐type viruses has been detected in the HeLa virus. However a distinct serological relationship was found between the HeLa virus and the Mason‐Pfizer monkey virus in that these viruses share at least two antigens in the mw range of 16,000 d and 28,000 d, respectively. These results confirm the electron microscopic data described before (Gelderblom et al. , 1974) and extend the evidence for a new group of oncornavirus‐like particles.
Selective Binding to Polynucleotides of the Hybrid Intercalating Groove Binder Bis(pyrrolecarboxamide)-oxazolopyridocarbazole: A Molecular Modeling Study (1994)

In order to further characterize the binding of the hybrid molecule NetOPC [bis(pyrrolecarboxamide)-oxazolopyridocarbazole conjugate] to double-stranded DNA, we have performed a molecular modeling study to investigate the binding modes of the complexes possibly formed between NetOPC and synthetic polynucleotides poly [(dA-dT)]2, poly [(dA).d(T)], and poly [d(G-C)]2 and interpreted the results in the light of the experimentally determined binding parameters. In agreement with experimental data, the modeling study suggests that whatever was the binding mode of the complex formed, the complexation energy is markedly lower (thus favorable) for AT-containing polynucleotides than for poly d[(G-C)]2. With both poly [d(A).d(T)] and poly [d(A-T)]2, the most energetically favored complex has netropsin and OPC moieties bound simultaneously in the minor groove of DNA. The second favored complex exhibits the bimodal binding, i.e., intercalation of OPC and minor groove binding of the netropsin moiety. For both types of complex, the energy of complex formation is slightly lower with poly [d(A).d(T)]. The binding site sizes of the modeled complexes are about seven and four base pairs to the full groove and bimodal binding, respectively.
Synthesis and Structure Analysis of Glucosylpsicose Produced by Cyclomaltodextrin Glucanotransferase (2008)

Glucosylpsicose was synthesized by transglycosylation with α-cyclodextrin and D-psicose using cyclomaltodextrin glucanotransferase (EC 2.4.1.19; CGTase). The structure of glucosylpsicose was analyzed by HPLC to determine sugar composition and molecular mass, by methylation analysis using GC-MS and by α- and β-glucosidase treatments to determine linkage, and 1H- and 13C-NMR spectrometries to obtain the anomeric configuration of the glycosidic linkage. By chemical analysis, it was found that the structure of glucosylpsicose is 1-o-α-D-glucopyranosyl-D-psicose.
PAPER 175: RADIOGRAPHIC QUANTIFICATION OF PINCER FEMOROACETABULAR IMPINGEMENT (2010)

Purpose: Femoroacetabular impingement (FAI) results from abnormal abutment between the proximal femur and acetabulum (Ganz et al., 2003). FAI occurs in three forms; cam, pincer and mixed (cam and pincer combined). The cam type has been quantified radiographically (Beall et al., 2005), but pincer FAI is poorly defined. Radiographic measures, including the center-edge angle (Wiberg, 1953), and Sharp’s angle (Sharp, 1961) have been used to define hip dysplasia, but these measures have not been used to define FAI. The purpose was to test these measurements to compare pincer patients with controls. Method: This study is a retrospective, observational analysis of anterior-posterior pelvic radiographs for control (N=76 hips; 40 patients) and pincer (N=20 hips; 19 patients) groups. Control radiographs were obtained from injury-free pelvic x-rays from the emergency department. Lateral center-edge (CE) angle Sharp’s angle and a proposed measurement of Femoral Head Containment (FHC) were measured using PACS. FHC was defined as the percentage of the 2D area of the femoral head circle covered by the acetabulum, using chord length, height and diameter of the femur head. Non-parametric statistics with post-hoc analyses were used. Pearson’s correlations were calculated for within- and between-observer reproducibility. Results: Mean (± SD) CE angle was significantly larger in the FAI group [37.4° (±5.2)] compared to controls [31.0° (±3.9)]. Mean Sharp’s angle was significantly less in the FAI group [37.6° (±3.9)] compared to the controls [41.2° (±3.5)]. Mean FHC was significantly larger in the FAI group [26.4% (±5.3)] compared to control group [21.5% (±5.3)]. Intra-observer r-values ranged from 0.86–0.97 and inter-observer correlations ranged from 0.93–0.96. There was significantly greater acetabular overcoverage in the pincer group based on these three measures, suggesting these may be used diagnostically. Conclusion: Pincer FAI is a debilitating condition that has not been quantified. This study found that CE angle, Sharp’s angle and FHC measures may be useful in diagnosing pincer FAI. A new method of quantifying FHC was proposed, evaluated and appears to be a promising new measure for evaluating pincer FAI. The CE and Sharp’s angles are simple, reproducible measures that can easily be used in a clinic setting to assist with diagnosing pincer FAI.
19-μm operation of a Tm:lead germanate glass waveguide laser (1994)

We report what we believe to be the first planar-technology waveguide laser in the 2-microm region. Laser operation of the (3)H(4) to (3)H(6) transition of Tm(3+) ions in a lead germanate glass host has been observed in an ion-implanted planar waveguide.
Superconducting Linac for Rare Isotope Science Project (2014)

Rare Isotope Science Project (RISP) has been proposed as a multi-purpose accelerator facility for providing beams of exotic rare isotopes of various energies. The RISP driver linac which is used to accelerate the beam, for an example, Uranium ions from 0.5 MeV/u to 200 MeV/u consists of superconducting RF cavities and warm quadrupole magnets for focusing heavy ion beams. Requirement of the linac design is especially high for acceleration of multiple charge beams. In this paper, we present the status of RISP linac design and the development of superconducting cavity and cryomodule.
