A pipelined maximal-sized matching scheme for high-speed input-buffered switches (2002)

This paper proposes an innovative Pipelinebased Maximal-sized Matching scheduling approach, called PMM, for input-bu ered switches. It dramatically relaxes the limitation of a single time slot for completing a maximal matching into any number of time slots. In the PMM approach, arbitration is operated in a pipelined manner, where K subschedulers are used. Each subscheduler is allowed to take more than one time slot for its matching. Every time slot, one of the subschedulers provides the matching result. We adopt an extended version of Dual Round-Robin Matching (DRRM), called iterative DRRM (iDRRM), as a maximal matching algorithm in a subscheduler. PMM maximizes the eAEciency of the adopted arbitration scheme by allowing suAEcient time for the number of iterations. We show that PMM preserves 100% throughput under uniform traAEc and fairness for best-e ort traAEc of the nonpipelined adopted algorithm, while ensuring that cells from the same virtual output queue (VOQ) are transmitted in sequence. In addition, we con rm that the delay performance of PMM is not signi cantly degraded by increasing the pipeline degree, or the number of subschedulers, when the number of outstanding requests for each subscheduler from a VOQ is limited to 1. key words: Scheduling, pipeline, input-bu ered switch, maximal-sized matching
Red Phosphorus Nanodots on Reduced Graphene Oxide as a Flexible and Ultra-Fast Anode for Sodium-Ion Batteries (2017)

Sodium-ion batteries offer an attractive option for potential low cost and large scale energy storage due to the earth abundance of sodium. Red phosphorus is considered as a high capacity anode for sodium-ion batteries with a theoretical capacity of 2596 mAh/g. However, similar to silicon in lithium-ion batteries, several limitations, such as large volume expansion upon sodiation/desodiation and low electronic conductance, have severely limited the performance of red phosphorus anodes. In order to address the above challenges, we have developed a method to deposit red phosphorus nanodots densely and uniformly onto reduced graphene oxide sheets (P@RGO) to minimize the sodium ion diffusion length and the sodiation/desodiation stresses, and the RGO network also serves as electron pathway and creates free space to accommodate the volume variation of phosphorus particles. The resulted P@RGO flexible anode achieved 1165.4, 510.6, and 135.3 mAh/g specific charge capacity at 159.4, 31878.9, and 47818.3 mA/g charge/discharge current density in rate capability test, and a 914 mAh/g capacity after 300 deep cycles in cycling stability test at 1593.9 mA/g current density, which marks a significant performance improvement for red phosphorus anodes for sodium-ion chemistry and flexible power sources for wearable electronics.
Bovine Pneumonic Pasteurellosis (1988)

The acknowledged efficacy of vaccination in preventing major infectious diseases is based upon obvious successes such as that against smallpox, which was declared eradicated in 1980 (24), or the Clostridium sp bacterin-toxoids which are used in man and animals. Expectations for vaccine usefulness are consequently high, but many diseases which are apparently amenable to vaccine-based control remain as significant sources of economic loss in the livestock industry. Failure to observe certain basic principles of vaccine design may have contributed to this. Vaccination is feasible and warranted if directed towards an economically important infectious disease of livestock which is caused by an identified infectious agent with known virulence-mediating determinants which induce protective immune response against a realistic challenge under usual husbandry conditions. The vaccination program must be cost-effective.
A batch-processed vacuum-sealed capacitive pressure sensor (2002)

This paper reports a multi-transducer vacuum-sealed capacitive barometric pressure sensor. The device operates with a resolution of 25 mTorr over a pressure range from 600 to 800 Torr. The sensitivity is 27 fF/Torr (3000 ppm/Torr). The TCO at 750 Torr is 3969 ppm//spl deg/C and the TCS is about 1000 ppm//spl deg/C. The device uses a single layer of polysilicon both for sealing to the glass and for transfer of the glass electrode in the reference cavity to the outside world. The device is read out using a switched-capacitor charge integrator and an on-chip compensation capacitor.
Joint signaling techniques for crosstalk-dominated communication channels (2003)

We present a framework for maximizing the capacity (or bit rate) of symmetric bit rate communication services dominated by crosstalk, in particular digital subscriber line (DSL) services. We assume the DSL channel is a Gaussian channel, so transmit power spectral density (PSD) design is sufficient to maximize bit rates. Using the channel, noise, and crosstalk transfer functions, we set up an optimization problem and solve for transmit PSDs that maximize the joint capacity of same service users. Joint signaling techniques and optimal power distribution yield significant gains in bit rates (or performance margins) over current schemes. Furthermore, the designed transmit PSDs are inherently spectrally compatible with existing services on neighboring lines. We purposefully design a general framework; it does not depend on the exact choice of modulation scheme, for example. It is also extremely simple and of low computational complexity. The framework can also apply to other channels besides DSLs, such as wireless channels, coaxial cables, power lines, and telemetry cables used in geophysical well-logging tools.
Making Progress Towards «Green» Propellants (2018)

Abstract Stabilisers are used in propellants to prevent the various effects such as oxidation, chain scission, energy loss and uncontrolled heat generation that are caused by homolytic and heterolytic cleavage of the weakest Nitrogen‐Oxygen bond of the nitrate ester functional group. Conventional stabilisers for nitrocellulose‐based propellants belong to a‐aromatic amines (e. g., diphenylamine, 4‐nitro‐N‐methylaniline…) or b‐aromatic urea derivatives (e. g., Akardite, centralite…) and are/or produce highly toxic and/or potentially carcinogenic species at some point during a propellant's lifetime. There is an obvious need for alternative stabilisers presenting a low toxicity profile and providing efficiencies similar to, or better than conventional stabilisers. This paper presents novel, environmentally friendly, efficient and readily‐available stabilisers for use in nitrocellulose‐based compositions. With REACh legislation (1907/2006), industry in Europe has made progress in using less toxic compounds, that are often more environmentally‐friendly. The aim of this work is to go beyond REACh and to anticipate the inclusion of other molecules that produce non‐ or less toxic daughter products and that can fulfil their role in the propellant's formulation.
Salt-Urea, Sulfopropyl-Sepharose, and Covalent Chromatography Methods for Histone Isolation and Fractionation (2013)

The histones are essential basic proteins intimately involved in most DNA-templated processes. Thus, their purification and fractionation for analysis and their use for in vitro chromatin transactions are of fundamental importance for understanding their role in chromatin structure and regulation of DNA functions. Here are described three new protocols for histone isolation from undisturbed whole cells. They avoid the conventional non-denaturing cell lysis, which affects the native posttranslational modifications of histones, and the cumbersome use of reverse-phase high-performance liquid chromatography. The three methodologies are shorter than the conventionally used protocols. The salt-urea method exploits the stability of the cell nucleus in salt solutions containing 8 M urea, whereas the cell cytoplasm and the majority of nuclear components, except H3/H4, are washed away. This protocol yields highly purified H3/H4 in a few minutes without the use of chromatography steps. The acid extraction-sulfopropyl (SP)-Sepharose protocol uses acidic solution for direct extraction of histones from undisturbed cells. Following extraction, the solution is neutralized with Tris-HCl, and run through a SP column. H2A/H2B are eluted from the SP-Sepharose at 0.8 M NaCl, with H3/H4 subsequently eluted at 2 M NaCl. This procedure yields highly purified H2A/H2B and H3/H4. Finally, covalent chromatography on thiopropyl-Sepharose (TPS) allows the separation of H3 from H4, by covalently binding H3 through its unique cysteine residue to the resin; H4 is recovered in the flow-through and wash fractions, and H3 is eluted with dithiothreitol.
Role of acetate during platelet storage in a synthetic medium (1992)

It has previously been shown that buffy coat platelet concentrates (BC-PCs) stored in a medium made up of approximately 70 percent platelet storage medium (Plasma-Lyte A, PL) and 30 percent plasma (BC-PC-P) are effective in vivo after 9 to 12 days of storage. In addition to sodium, potassium, magnesium, and chloride, PL contains 27 mM (27 mmol/L) sodium acetate and 23 mM (23 mmol/L) sodium gluconate. This study investigated the effect of acetate and gluconate on platelet metabolism. Identical BC-PCs were stored at 22 +/- 2 degrees C in PL (BC-PC-P); PL with gluconate but without acetate, termed PL-A (BC-PC-A); or PL with acetate but without gluconate, termed PL-G (BC-PC-G). On Day 1 of storage, no significant differences were seen between the three groups of BC-PCs. In both BC-PC-P and BC-PC-G, pH and bicarbonate were stable at 7.0 +/- 0.03 and 8.4 +/- 0.9 mEq per L throughout 10 days of storage, whereas in BC-PC-A, they fell to 6.7 +/- 0.05 and 5.5 +/- 0.8 mEq per L on Day 5 (p less than 0.01 vs. Day 1) and to 6.1 +/- 0.1 and 1.2 +/- 0.4 mEq per L, respectively, on Day 10. The buffering capacities of 70 percent PL, PL-A, or PL-G and 30 percent plasma were similar in a platelet-free setting when incremental additions of lactic acid were made. The role of acetate was further studied by adding 14C- or 3H-labeled acetate to BC-PC-P.(ABSTRACT TRUNCATED AT 250 WORDS)
Comparative oncological studies of feline bronchioloalveolar lung carcinoma, its derived cell line and xenograft. (2002)

Although certain neoplasms are unique to man, others occur across species. One such neoplasm is bronchioloalveolar lung carcinoma (BAC), a neoplasm of the Type II pneumocyte that affects humans, sheep, and small animals (dogs and cats). Human BAC occurs largely in nonsmokers. Sheep BAC is caused by the jaagsiekte retrovirus and is endemic and contagious. Feline BAC is neither endemic nor contagious and occurs sporadically and spontaneously in older purebred cats. In these respects, feline BAC is more closely similar to human BAC than sheep BAC (jaagsiekte) is. To study feline BAC further, we established the first immortal cell line (SPARKY) and transplantable scid mouse xenograft (Sparky-X) from a malignant pleural effusion of a 12-year-old Persian male with autopsy-confirmed BAC. SPARKY exhibited a Type II pneumocyte phenotype characterized by surfactant and thyroid-transcription factor-1 immunoreactivities and lamellar bodies. SPARKY's karyotype was aneuploid (66 chromosomes: 38, normal cat) and showed evidence of genomic instability analogous to human lung cancers. p53 showed a homozygous G to T transversion at codon 167, the feline equivalent of human codon 175, one of the many hot spots mutated in the lung cancers of smokers. H-ras and K-ras were not altered. By reverse transcription-PCR, SPARKY lacked expression of retroviral JSRVgag transcripts that were present in the lungs of sheep BAC (jaagsiekte). Unlike human BAC xenografts, SPARKY-X retained its unique lepidic BAC growth pattern even though it was grown in murine s.c. tissues. This property may be related to the ability of SPARKY-X to up-regulate its surfactant genes (SP-A, SP-B, and SP-D). These studies of feline BAC may allow insights into the human disease that are not possible by studying human BAC directly.
Motion-Compensated Coding: Some New Results (1980)

In earlier papers, we have presented motion-compensated television coding schemes in which the displacement of objects was recursively estimated using a steepest descent algorithm that minimized the square of the intensity prediction error at each picture element. In this paper, we present extensions in which displacement is estimated by considering the prediction error at several picture elements. These extensions are more complex, but they significantly improve the performance of the displacement estimation in those cases where the displacement is spatially uniform. However, in real scenes containing large spatial variations of displacement, only a small improvement is obtained. For one scene containing a head-and-shoulders view of a person engaged in active conversation, an improvement of about 10 percent in average bit rate was obtained over our previous motion-compensation scheme.
Automatic scan prescription for brain MRI (2001)

Diagnostic brain MRI scans are usually performed by trained medical technologists who manually prescribe the position and orientation of a scanning volume. In this study, a fully automatic computer algorithm is described which compensates for variable patient positioning and acquires brain MRI scans in a predefined reference orientation. The method involves acquiring a rapid water-only pilot scan, segmenting the brain surface, and matching it to a reference surface. The inverse matching transformation is then used to adapt a geometric description of the desired scanning volume, defined relative to the reference surface, to the current patient. Both pilot scan and processing are performed within 30 sec. The method was tested in 25 subjects, and consistently recovered orientation differences between the reference and each subject to within +/-5 degrees. Compared to manual prescription, automatic scan prescription promises many potential benefits, including reduced scan times, reproducible scan orientations along anatomically preferable orientations, and better reproducibility for longitudinal studies.

Structural elucidation of an  -1,2-mannosidase resistant oligosaccharide produced in Pichia pastoris (2011)

The N-glycosylation pathway in Pichia pastoris has been humanized by the deletion of genes responsible for fungal-type glycosylation (high mannose) as well as the introduction of heterologous genes capable of forming human-like N-glycosylation. This results in a yeast host that is capable of expressing therapeutic glycoproteins. A thorough investigation was performed to examine whether glycoproteins expressed in glycoengineered P. pastoris strains may contain residual fungal-type high-mannose structures. In a pool of N-linked glycans enzymatically released by protein N-glycosidase from a reporter glycoprotein expressed in a developmental glycoengineered P. pastoris strain, an oligosaccharide with a mass consistent with a Hexose(9)GlcNAc(2) oligosaccharide was identified. When this structure was analyzed by a normal-phase high-performance liquid chromatography (HPLC), its retention time was identical to a Man(9)GlcNAc(2) standard. However, this Hexose(9)GlcNAc(2) oligosaccharide was found to be resistant to α-1,2-mannosidase as well as endomannosidase, which preferentially catabolizes endoplasmic reticulum oligosaccharides containing terminal α-linked glucose. To further characterize this oligosaccharide, we purified the Hexose(9)GlcNAc(2) oligosaccharide by HPLC and analyzed the structure by high-field one-dimensional (1D) and two-dimensional (2D) (1)H NMR (nuclear magnetic resonance) spectroscopy followed by structural elucidation by homonuclear and heteronuclear 1D and 2D (1)H and (13)C NMR spectroscopy. The results of these experiments lead to the identification of an oligosaccharide α-Man-(1 → 2)-β-Man-(1 → 2)-β-Man-(1 → 2)-α-Man-(1 → 2) moiety as part of a tri-antennary structure. The difference in enzymatic reactivity can be attributed to multiple β-linkages on the α-1,3 arm of the Man(9)GlcNAc(2) oligosaccharide.
Evaluation of Golden-Angle-Sampled Dynamic Contrast-Enhanced MRI Reconstruction Using Objective Image Quality Measures: A Simulated Phantom Study (2020)

We aim to extend the use of image quality metrics (IQMs) from static magnetic resonance imaging (MRI) applications to dynamic MRI studies. We assessed the use of 2 IQMs, the root mean square error and structural similarity index, in evaluating the reconstruction of quantitative dynamic contrast-enhanced (DCE) MRI data acquired using golden-angle sampling and compressed sensing (CS). To address the difficulty of obtaining ground-truth knowledge of parameters describing dynamics in real patient data, we developed a Matlab simulation framework to assess quantitative CS-DCE-MRI. We began by validating the response of each IQM to the CS-MRI reconstruction process using static data and the performance of our simulation framework with simple dynamic data. We then extended the simulations to the more realistic extended Tofts model. When assessing the Tofts model, we tested 4 different methods of selecting a reference image for the IQMs. Results from the retrospective static CS-MRI reconstructions showed that each IQM is responsive to the CS-MRI reconstruction process. Simulations of a simple contrast evolution model validated the performance of our framework. Despite the complexity of the Tofts model, both IQM scores correlated well with the recovery accuracy of a central model parameter for all reference cases studied. This finding may form the basis of algorithms for automated selection of image reconstruction aspects, such as temporal resolution, in golden-angle-sampled CS-DCE-MRI. These further suggest that objective measures of image quality may find use in general dynamic MRI applications.
Crystal Defects in CdZnTe Crystals Grown by the Modified Low-Pressure Bridgman Method (2012)

Cadmium Zinc Telluride (CZT) is among the most promising materials for room-temperature X- and gamma-ray detectors. However, crystal defects such as Te inclusions and subgrain boundaries significantly hamper their performances. In this work, we evaluated CZT crystals grown by the modified low-pressure Bridgman technique at the IMEM Institute, Parma. We characterized the crystals by IR microscopy to identify the sizes and concentrations of the Te inclusions, along with high spatial resolution X-ray response mapping to measure the uniformity of their charge-transport properties. In addition, we employed white X-ray beam diffraction topography to analyze their crystalline structure.

A highly active and site selective indium catalyst for lactide polymerization (2012)

Chiral indium salen complexes are highly active, isoselective catalysts for the ring opening polymerization of racemic lactide. The polymerizations are well controlled and polymers with high molecular weights and low molecular weight distributions are obtained. Preliminary kinetic investigations with the enantiopure complex confirm enantiomorphic site control as the dominant contributor to selectivity and formation of block copolymers.

Separation of Fullerenes C<sub>60</sub>, C<sub>70</sub>, and C<sub>76</sub>-84 on Polystyrene Divinylbenzene Columns (1993)

Abstract New HPLC methods have been developed to effectively separate and recover essentially pure amounts of C60 and C70 fullerenes from the lower MW contaminants and higher MW fullerenes co-extracted from carbon soot. Separation with toluene/methylene chloride mobile phase results from different degrees of interaction of conjugated π-electrons of the fullerenes and the polystyrene divinylbenzene (PSDVB) resin stationary phase. The presence of either toluene or CS2 in the mobile phase attenuates π-electron interactions. The separation mechanism becomes predominantly size exclusion chromatography for a CS2 concentration in the mobile phase ≥ 60%. Excellent separation of C60, C70 and C76–84 is obtained with the analytical Envirosep-ABC(tm) columns in less than 15 minutes. Substituted fullerene reaction products are also well separated from their parent compounds. The effects of column size and PSDVB pore size on analytical separation, along with the effects of pore size, mobile phase, and sample size on semi-preparative separation of C60 and C70 are reported. Semi-preparative columns can process with satisfactory resolution more than 14.5 mg of fullerenes per run using methylene chloride:toluene as mobile phase. These studies led to the development of an optimized set of columns consisting of a guard column (60×21.2 mm) and a modified preparative column (350×21.2 mm) with improved flow design and separation efficiency.
