Hemoglobin Levels Above Anemia Thresholds Are Maximally Predictive for Long-Term Survival in COPD With Chronic Respiratory Failure (2013)

In subjects with COPD and chronic respiratory failure undergoing treatment with noninvasive ventilation and LTOT, high Hb levels are associated with better long-term survival. The optimal cutoff level for prediction was above the established threshold defining anemia. Thus, predicting survival only on the basis of anemia does not fully utilize the prognostic potential of Hb values in COPD.
Surveillance Imaging for Lymphoma: Pros and Cons (2014)

There is no international consensus on the optimal frequency or duration of computed tomography or positron emission tomography scanning for surveillance in patients who achieve complete remission after initial therapy for lymphoma. Although some clinical practice guidelines suggest periodic imaging is reasonable, others suggest little or no benefit to this practice. From a theoretical perspective, the frequency and duration of surveillance imaging is largely dependent upon the lymphoma subtype. Aggressive lymphomas with a fast growth rate will require surveillance more frequently and for a shorter duration compared to the indolent lymphomas. Historically, relapse has been detected in a majority of patients based upon clinically evident signs and symptoms. Currently, no study has demonstrated an overall survival difference for patients with relapse detected by imaging as opposed to clinical evaluation, although one study did demonstrate a lower second-line International Prognostic Index in patients with relapse detected by surveillance imaging. Enthusiasm for this finding has been tempered by recent studies highlighting the potential long-term risk of secondary malignancies because of ionizing radiation exposure from diagnostic imaging. These factors along with the significant costs associated with diagnostic imaging have contributed to an ongoing debate regarding the relative costs, risks, and benefits of radiographic surveillance. Herein we present perspectives for and against routine surveillance imaging in an effort to facilitate a better understanding of the issues relevant to what is ultimately a clinical decision made by an oncologist and his or her patient.

Controllability of Multi-Agent Systems from a Graph-Theoretic Perspective (2009)

In this work, we consider the controlled agreement problem for multi-agent networks, where a collection of agents take on leader roles while the remaining agents execute local, consensus-like protocols. Our aim is to identify reflections of graph-theoretic notions on system-theoretic properties of such systems. In particular, we show how the symmetry structure of the network, characterized in terms of its automorphism group, directly relates to the controllability of the corresponding multi-agent system. Moreover, we introduce network equitable partitions as a means by which such controllability characterizations can be extended to the multileader setting.
Syntheses of Two Dopo-Based Reactive Additives as Flame Retardants and Co-Curing Agents for Epoxy Resins (2014)

Two novel phosphorus-nitrogen-containing flame retardants, 1,1′,2,2′-tetra-hydroxyl-4′′, 4′′′-biphenylene-bis[amino-((10′′′′-O-10′′′′-H-9′′′′-oxa-10′′′′λ5-phosphaphenanthrene-10′′′′-yl))-methyl]}-bisphenol (3) and 1,1′,2,2′-tetra-hydroxyl-{4′′,4′′′-phenylene-bis[amino-((10′′′′- O-10′′′′- H-9′′′′- oxa-10′′′′λ5-phosphaphenanthrene-10′′′′-yl))-methyl]}-bis-phenol (4) were synthesized by two steps: 1,1′,2,2′-tetra-hydroxyl-{4′′,4′′′- bi-phenylene-bis[amino-methyl]}-bis-phenol, imine (1), was synthesized through condensation reaction between 3,4-dihydroxybenzaldehyde and 4,4′-diaminobiphenyl; and, 1,1′,2,2′-tetra-hydroxyl-{4′′,4′′′- phenylene-bis[amino-methyl]}-bis-phenol, imine (2) was synthesized by the reaction of 3,4-dihydroxybenzaldehyde and 1,4-phenylenediamine; then, addition reactions between 9,10-dihydro-9-oxa-10- phosphaphenanthrene-10-oxide and the two imines, the (3) and (4) were obtained, respectively. (1)–(4) were characterized by FTIR, NMR, and MS. (3) and (4) reacted with epoxy resins as co-curing agents with 4,4′-diaminodiphenylmethane. Compared with control samples, (3) or (4) co-cured epoxy thermosets with phosphorus content of 1.0 wt% possessed good flame retardant properties with LOI value reaching more than 36.0, higher char yields. The glass translation temperature (Tg) of thermosets containing (3) or (4) were characterized with suitable changes by DSC test.
Distribution of Hydrate Saturation Ratios in Artificial Methane Hydrate Sediments Measured by High-Speed X-Ray Computerized Tomography (2005)

A high-speed X-ray computerized tomography (CT) system was developed for measuring the texture of methane hydrate sediment. The system enabled time dependent nondestructive observations of the hydrate sediment in a volume of φ100×100 mm 3 within 40 s. The spatial variation of mass density and the volume fraction of an artificial methane hydrate sediment that is either ice or hydrate, hereafter referred to as the hydrate saturation ratio within methane hydrate sediments, were measured using the X-ray CT system. The three-dimensional (3D) distribution change of density and hydrate saturation caused by the hydrate dissociation were also visualized on the basis of the measured gray scale values of the CT images taken before and after their dissociation. The technique allows us observations of the dissociation process of methane hydrate sediment under experimental conditions which are the same as conditions in the natural environment, and will allow the simulation of methane gas production from wells in both oceanic and permafrost areas.
Structure and Properties of Functionalized Bithiophenesilane Monodendrons (2009)

This study reports a focal group modification of bithiophenesilane monodendrons and its effect on their molecular ordering in solution, bulk, and surface. We investigated hydrophobic MDn monodendrons and COOH-functionalized MDn-COOH monodendrons with generations, n=0, 1, 2, and 3. We observed that increasing the number of branches led to the progressive blue shift, indicating distorted packing of branched thiophene fragments of MDn. In contrast, MDn-COOH monodendrons showed a progressive red shift with the increasing generation number, indicating gradual domination of sigma-pi interactions. Moreover, the introduction of a focal carboxylic group resulted in the formation of a highly crystalline state for the linear MD0-COOH compound with separated alkyl tail-thiophene packing, which limits pi-pi interactions. Increasing branching in the COOH-containing monodendrons resulted in a hydrophobic-hybrophilic balance sufficient to form stable and uniform Langmuir monolayers at the air-water at a modest surface pressure (<10 mN/m), easily transferrable to a solid substrate. However, a further increase in the thickness of the surface layers from tens to hundreds of nanometers via Langmuir-Blodgett (LB) deposition or spin casting is limited by the formation of globular surface aggregates because of strong intermolecular interactions. A modest red shift observed for condensed Langmuir monolayers indicates densification of thiophene branches and limited intramonolayer crystallization, which preserves photoluminescence. In contrast, thicker surface films showed a significant red shift, confirming a dense molecular packing with strong pi-pi interactions, which results in photoluminescence quenching.
Is There a Relationship of Operator and Center Volume With Access Site–Related Outcomes? (2016)

The lower mortality associated with transradial access adoption relates to both the total procedural volume and the proportion of procedures undertaken radially by operator, with operators undertaking the greatest proportion of their procedures radially having the largest relative reduction in mortality risk.

Folding and unfolding of a non-fluorescent mutant of green fluorescent protein (2007)

Green fluorescent protein (GFP), from the Pacific jellyfish A. victoria, has numerous uses in biotechnology and cell and molecular biology as a protein marker because of its specific chromophore, which is spontaneously created after proper protein folding. After formation, the chromophore is very stable and remains intact during protein unfolding, meaning that the GFP unfolding process is not the reverse of the original folding reaction; i.e., the principles of microscopic reversibility do not apply. We have generated the mutant S65T/G67A-GFP, which is unable to form the cyclic chromophore, with the goal of investigating the folding, unfolding and competing aggregation of GFP under fully reversible conditions. Our studies have been performed in the presence of GdnHCl. The GFP conformation was monitored using intrinsic tryptophan fluorescence, and fluorescence of bis-ANS. Light scattering was used to follow GFP aggregation. We conclude from these fluorescence measurements, that S65T/G67A-GFP folding is largely reversible. During equilibrium folding, the first step is formation of molten globule, prone to aggregation.
The small gtp-binding protein, RHO p21, is involved in bone resorption by regulating cytoskeletal organization in osteoclasts (1995)

Rho protein (rho p21), a p21ras-related small guanine nucleotide binding protein, regulates cytoskeletal organization in a number of different types of cells. Evidence has indicated that Clostridium botulinum-derived ADP-ribosyltransferase (C3 exoenzyme) specifically ADP-ribosylates rho p21 at Asn41 and renders it functionally inactive. In this study, we examined the involvement of rho p21 in osteoclastic bone resorption using the C3 exoenzyme. When osteoclast-like multinucleated cells obtained from cocultures of mouse osteoblastic cells and bone marrow cells were placed on dentine slices, they formed ringed structures of podosomes containing F-actin (corresponding to the clear zone) within 8 hours. Many resorption pits were formed on dentine slices after culture for 24 hours. The C3 exoenzyme at 0.15-10 micrograms/ml added to the culture medium disrupted the ringed structure of podosomes in osteoclast-like cells in a dose-dependent manner. Correspondingly, pit formation by osteoclast-like cells on dentine slices was dose-dependently inhibited also by adding the C3 exoenzyme. Microinjection of the C3 exoenzyme into osteoclast-like cells placed on culture dishes completely disrupted the ringed podosome structure within 20 minutes. The amount of the rho p21 which was ADP-ribosylated by the C3 exoenzyme in vitro was much greater in purified osteoclast-like cells than in osteoblastic cells. Prior exposure of the purified osteoclast-like cell preparation to the C3 exoenzyme in vivo markedly decreased the amount of unribosylated rho p21. This indicated that the C3 exoenzyme incorporated into osteoclast-like cells effectively ADP-ribosylates rho p21 in vivo.(ABSTRACT TRUNCATED AT 250 WORDS)

Java for Safety-Critical Applications (2009)

In recent years, various approaches to real-time execution of Java have proven their worth in numerous commercial and defense applications. The Real-time Specification for Java has extended the Java platform with a range of features needed for real-time computing. As the use of real-time Java has become more widespread, the demand for Java in real-time applications with safety requirements has led to an eort to define a new standard—JSR-302 Safety-Critical Java (SCJ). The goal of this standard is to facilitate the creation of safety-critical Java applications capable of certification under standards such as DO 178B level A or IEC61508 for SIL 4. JSR-302 is nearing completion and will soon be released for public review. This paper introduces some of the primary goals, challenges, and proposed solutions for safety-critical Java and its relationship with the Real-time Specification for Java.
74. Cellular Immunity to Adeno-Associated Virus Capsid Attenuates Transgene Expression in the Liver (2006)

Adeno-associated virus (AAV) vectors hold the potential to treat a variety of inherited and acquired human diseases. One of the confounding issues regarding the use of AAV in humans is the cellular immune response to the virus vector. While the ability of humoral immunity to interfere with AAV transduction is well-established, the ability of cellular immunity targeting the vector to ablate AAV transduction has only recently been identified. Our laboratory previously described the use of adenovirus expressing AAV capsid as a means to invoke a cellular immune response towards AAV in a mouse model system. These studies identified the immunodominant CD8 T-cell epitopes in Balb/C and C57Bl/6 mice immunized against AAV capsid of serotypes 2 and 8 (Mol Ther. 2005 Dec;12(6):1023–33). Cytolytic potential of these AAV capsid specific T-cells, however, was not investigated. In the current study, we seek to determine whether cellular immune responses reduce the efficiency of AAV transduction. We first evaluated the cytolytic activity of AAV capsid specific T-cells using a sensitive in vivo killing assay. In this assay, naïve murine splenocytes were loaded with either an immunodominant AAV peptide or an irrelevant AAV peptide. To discriminate between the two populations, each was labeled with a different concentration of CFSE dye. The two cell populations were then mixed together in equal numbers and injected into the tail vein of naïve and AAV- immune mice. Nearly equal proportions of both labeled subsets were recovered from naïve mice. In contrast, AAV-immune mice efficiently destroyed splenocytes loaded with the immunodominant AAV peptide. Percent specific lysis was greater than 70% for three out of four immunodominant peptides tested. These results show that AAV immunized mice harbor potent cytotoxic activity directed towards AAV capsid. We subsequently tested the ability of splenocytes from AAV-immune mice to reduce long-term AAV-mediated transgene expression in the liver. Naïve mice were first injected via the portal vein with 5×1010 vector genomes encapsidated by AAV-2 or AAV-8 capsid. These vectors encoded the human factor IX (hFIX) gene expressed under the control of a liver-specific promoter. Following a delay of 1–2 hours, these mice then received an adoptive transfer of splenocytes harvested from capsid matched AAV-immune mice. Control mice received adoptive transfer of splenocytes from naïve mice. Two months post-infusion, mice that received adoptive transfer from AAV-2 immune mice expressed significantly lower levels of hFIX than mice receiving adoptive transfer of naïve splenocytes (775ng/mL vs. 1771ng/mL, p=.03). Recipients of adoptive transfer from AAV-8 immune mice similarly exhibited reduced levels of hFIX two months post-infusion compared to control mice (606ng/mL vs. 1637ng/mL, p=.04). We conclude from these studies that a cellular immune response specific for AAV capsid can reduce AAV-mediated gene transfer in the liver.
New Binary Constant Weight Codes Based on Cayley Graphs of Groups and Their Decoding Methods (2005)

We propose a new class of binary nonlinear codes of constant weights derived from a permutation representation of a group that is given by a combinatorial definition such as Cayley graphs of a group. These codes are constructed by the following direct interpretation method from a group: (1) take one discrete group whose elements are defined by generators and their relations, such as those in the form of Cayley graphs; and (2) embedding the group into a binary space using some of their permutation representations by providing the generators with realization of permutations of some terms. The proposed codes are endowed with some good characteristics as follows: (a) we can easily learn information about the distances of the obtained codes, and moreover, (b) we can establish a decoding method for them that can correct random errors whose distances from code words are less than half of the minimum distances achieved using only parity checking procedures.
Silica single-layer inverse opal films: large-area crack-free fabrication and the regulation of transmittance in the visible region (2019)

Minority carrier transport in p-ZnO nanowires (2011)

In this work, we explore the minority carrier diffusion length in zinc oxide nanowires, using the electron beam-induced current technique. Systematic measurements as a function of temperature were performed on p-type, Sb-doped ZnO film, containing a 4 μm thick nanowire layer. The minority carrier diffusion length exhibits a thermally activated increase with the energy of 74±5 meV. Electron beam irradiation also causes the diffusion length increase with the activation energy of 247±10 meV, likely related to SbZn–2VZn acceptor-complex.
Incremental Recurrent Neural Network Dependency Parser with Search-based Discriminative Training (2015)

We propose a discriminatively trained recurrent neural network (RNN) that predicts the actions for a fast and accurate shift-reduce dependency parser. The RNN uses its output-dependent model structure to compute hidden vectors that encode the preceding partial parse, and uses them to estimate probabilities of parser actions. Unlike a similar previous generative model This beam search prunes after each shift action, so we add a correctness probability to each shift action and train this score to discriminate between correct and incorrect sequences of parser actions. We also speed up parsing time by caching computations for frequent feature combinations, including during training, giving us both faster training and a form of backoff smoothing. The resulting parser is over 35 times faster than its generative counterpart with nearly the same accuracy, producing state-of-art dependency parsing results while requiring minimal feature engineering.

Investigation of flexoelectric properties of a palladium-containing nematic liquid crystal, Azpac, and its mixtures with MBBA (1995)

Abstract Flexoelectricity of pure Azpac (an HOAB-palladium complex) was studied using planar nematic layers under an in-plane electric field. Longitudinal domains were observed with a period inversely proportional to the applied d.c. electric field. These domains were considered as a first experiment manifestation of the theoretical prediction of R. B. Meyer (1969) and their study has permitted the evaluation of the difference in flexo-coefficientse 1z - e 3x. Their appearance can also be followed for the non-complexed HOAB, using instant video-microscopy frames. Mixtures of Azpac, up to 10wt%, and MBBA were oriented homeotropically and band flexoelectric deformations were observed, both in d.c. and in a.c. (1 to 1000 Hz) electric fields normal to the director. The dynamics of director reorientation were studied by the method of flexoelectric light modulation. A system comprising a He-Ne laser and a lock-in amplifier interfaced by a PC was developed. By operating this in a frequency sweep regime, viscoelastic spectra of director dynamics were recorded. These spectra were excited using a linear flexoelectric coupling mechanism. Breaks in the spectra were observed in the range 200 to 600 Hz, indicating a cross-over from bulk to surface dissipation of energy. For the first time, a surface viscosity of 2.6 × 10−8Jsm−2 was determined for MBBA homeotropically anchored on a DMOAP-coated glass surface. In concentrations at low as 2.5 wt%, Azpac was found to cancel the bend flexo-coefficient of MBBA and at higher concentrations, a steep rise in the flexo-coefficient of the mixture was observed, but with an opposite sign. Thus, the application of Azpac as an effective additive for adjustment of the value and sign of the flexo-coefficient in flexoelectro-optic displays or light modulators could be suggested.
