Dielectric Properties of PMMA-SiO<sub>2</sub> Hybrid Films (2010)

Organic-inorganic hybrid films were synthesized by a modified sol-gel process. PMMA-SiO2 films were prepared using methylmethacrylate (MMA), tetraethil-orthosilicate (TEOS) as silicon dioxide source, and 3-trimetoxi-silil-propil-methacrylate (TMSPM) as coupling agent. FTIR measurements were performed on the hybrid films to confirm the presence of PMMA-SiO2 bonding. In addition, metal-insulator-metal (MIM) devices were fabricated to study the dielectric constant of the films as function of frequency (1 KHz to 1 MHz). Electrical results show a weak trend of the dielectric constant of the hybrid films with MMA molar ratio. More importantly, the PMMA-SiO2 hybrid films showed a higher dielectric constant than SiO2 and PMMA layers, which is likely due to the presence of additional C-O-C bond.
The relationship between telomere length and therapy-associated cytogenetic responses in patients with chronic myeloid leukemia (1997)

These findings suggest that normal TRFs in a small number of CML patients at the time of diagnosis may have a significant amount of normal stem cells remaining. The authors suggest that normal TRFs at the time of diagnosis indicate a subset of CML patients who may respond favorably to alpha-interferon therapy.
e0382 Relationship between brain natriuretic peptide levels in patients with acute coronary syndrome after percutaneous coronary intervention and cardiovascular events (2010)

<h3>Objective</h3> To analyse the relationship between in patients with acute coronary syndrome (ACS) at 48 h after percutaneous coronary intervention (PCI) and the relationship between the variation of brain natriuretic peptide (BNP) and the short and long-term cardiovascular events. <h3>Methods</h3> 156 patients with ACS were given conventional preoperative and postoperative medication and standardised PC1. Plasma levels of BNP were measured at 48 h after operations. All patients were divided into two groups according to the level of BNP: A group (BNP&gt;80pg/ml) and B group (BNP&lt;80pg/ml). The incidence of cardiovascular events during hospitalisation and at 6 months after PCI was analysed. <h3>Results</h3> Cardiovascular events during hospitalisation in A group included 12 cases, of which 3 died, heart failure occurred in 7 cases; recurrence myocardial infarction and angina in 1 case. 6 months after PCI, there were 4 cases of patients with heart failure and angina occurred in 5 cases. In group B, there were 7 cases of cardiovascular events, 0 deaths, 5 cases of heart failure, angina occurred in 2 cases. Six months later, cardiovascular events occurred in 6 cases, non-cardiac death in 2 cases; heart failure in 3 cases and angina in one. Compared with B group, the incidence of cardiovascular events in A group was significantly higher during hospitalisation (p&lt;0.01), but no different at 6 months after PCI (p&gt;0.05). <h3>Conclusion</h3> BNP concentration in patients with ACS at 48 h after PCI can only predict short-term prognosis, but cannot predict the long-term prognosis.
Shielding effect enables fast ion transfer through nanoporous membrane for highly energy-efficient electrodialysis (2023)

Abstract A key to sustainable management of saline organic-rich wastewaters is to precisely fractionate organic components and inorganic salts (NaCl) as individual resources. Conventional nanofiltration and electrodialysis processes suffer from membrane fouling and compromise the fractionation efficacy. Here we develop a thin-film composite nanoporous membrane via co-deposition of dopamine and polyethyleneimine as a highly anion-conducting membrane. Experimental results and molecular dynamics simulations show that co-deposition of dopamine and polyethyleneimine effectively tailors the membrane surface properties, intensifying the charge shielding effect and enabling fast anion transfer for highly efficient electrodialysis. The resulting nanoporous membrane exhibits unprecedented electrodialytic fractionation of organics and NaCl with negligible membrane fouling, dramatically outperforming state-of-the-art anion exchange membranes. Our study sheds light on facile design of high-performance anion-conducting membranes and associated new mass transport mechanisms in electrodialytic separation, paving the way for sustainable management of complex waste streams.

Estimation of performance loss due to delay in channel feedback in MIMO systems (2005)

Latency of available channel state information (CSI) at the transmitter in time-varying channels greatly affects the performance of multiple-input multiple-output (MIMO) systems. We have derived a simple algorithm to calculate an approximation of the expected performance loss based on the most recent channel feedback. The proposed algorithm can be used to determine the maximum tolerable channel feedback delay for each particular channel realization.
Long life hydrocarbon conversion catalyst and method of making (2023)

The present invention includes a catalyst that has at least four layers, (1) porous support, (2) buffer layer, (3) interfacial layer, and optionally (4) catalyst layer. The buffer layer provides a transition of thermal expansion coefficient from the porous support to the interfacial layer thereby reducing thermal expansion stress as the catalyst is heated to high operating temperatures. The method of the present invention for making the at least three layer catalyst has the steps of (1) selecting a porous support, (2) solution depositing an interfacial layer thereon, and optionally (3) depositing a catalyst material onto the interfacial layer; wherein the improvement comprises (4) depositing a buffer layer between the porous support and the interfacial layer.
Deposition of Pb(Zr x Ti 1-x )O 3 thin films by laser ablation for MEMS application (2002)

Pb(Zr<sub>x</sub>Ti<sub>1-x</sub>)O<sub>3</sub> films were prepared by pulsed laser ablation on Pt/Ti/SiO<sub>2</sub>/Si substrates at room temperature and were crystallized by subsequent annealing. The effect of the Pb content and Zr/Ti ratio in the target on crystalline structure and electrical properites of Pb(Zr<sub>x</sub>Ti<sub>1-x</sub>)O<sub>3</sub> films was investigated. Crystalline phases and structure in the PZT films were investigated by x-ray diffration analysis (XRD). The microstructure and composition of the films were studied by scanning electron microscopy (SEM) and electron probe microanalysis (EPMA), respectively. It was found that the adition of 20 wt% excess PbO to the PZT target is necessary to obtain a single perovskite phase. X-ray diffraction analysis results show that the film fabricated from the target with Zr/Ti ratio of 30/70 crystallizes in the tetragonal phase, while the films fabricated from the targets with Zr/Ti ratios of 70/30, 58/42, 52/48, 45/55 crystallite in the rhombohedral phase. The films derived from the target with Zr/Ti ratio of 45/55 and with 20 wt% excess PbO exhibited better electric properties. The remnant polarization and coercive field of the film were 31.28 &mu;C/cm2 and 45.29kV/cm, while the dielectric constant and loss value measured at 1 kHz were approximately 1069 and 0.08, respectively. The results demonstrate that a few micrometers thick PZT thin films derived by laser ablation for use in micro actuators is possible.

Promises and Problems of Mesoscale Materials Chemistry or Why Meso? (2003)

Manipulation and control of chemical structures on the mesoscale has recently developed to a very promising and also aesthetically appealing area of chemistry. This concept article tries to integrate the views of two experts to delineate the specific principles, approaches, and the novel opportunities for chemistry that arise from the rational control of matter and functionality on that scale.

Tubularized Neourethra Following Radical Retropubic Prostatectomy (1993)

A 1.5 cm. tubularized neourethra was formed using an anterior bladder flap as part of bladder neck reconstruction after radical retropubic prostatectomy in 69 consecutive patients with clinically localized prostate cancer (study group). Postoperative continence (defined as requiring no protection for any activity) was assessed by history at 3 months (all men) and 6 months (45 of 69 men). Continence in the study group was compared to that of 45 men with 6 months of followup who underwent radical retropubic prostatectomy without tubularization of the anterior bladder (control group). At 3 months 38 of 69 men (55%) were continent in the study group and 14 of 45 (31%) were continent in the control group (p < 0.03). At 6 months 39 of 45 men (87%) were continent in the study group compared to 21 of 45 (47%) in the control group (p < 0.01). Upright cystograms performed on men with and without the tubularized neourethra after radical retropubic prostatectomy suggest that a neourethra proximal to the external sphincter may increase resistance in this area and result in early return of urinary control in men undergoing radical retropubic prostatectomy.
Genetic characterization of the pnuC gene, which encodes a component of the nicotinamide mononucleotide transport system in Salmonella typhimurium (1989)

The pnuC gene, which encodes a component of the nicotinamide mononucleotide transport system, has been mapped and oriented. The gene order of the pnuC region, which is at min 17 of the Salmonella chromosome, is nadA-pnuC-aroG-gal. Polarity tests, with pnuC::Mu d-lac operon fusions, reveal that the pnuC gene is the promoter distal gene in an operon with the nadA gene, which encodes the second enzyme of the pyridine biosynthetic pathway. The nadA pnuC operon is regulated by the NadI repressor. The pnuC gene also has its own promoter, since strains with a nadA::Tn10d(Tc) insertion still express the pnuC gene at a low, unregulated level.
A Raman-Based Portable Fuel Analyzer (2010)

Fuel is the single most import supply during war. Consider that the US Military is employing over 25,000 vehicles in Iraq and Afghanistan. Most fuel is obtained locally, and must be characterized to ensure proper operation of these vehicles. Fuel properties are currently determined using a deployed chemical laboratory. Unfortunately, each sample requires in excess of 6 hours to characterize. To overcome this limitation, we have developed a portable fuel analyzer capable of determine 7 fuel properties that allow determining fuel usage. The analyzer uses Raman spectroscopy to measure the fuel samples without preparation in 2 minutes. The challenge, however, is that as distilled fractions of crude oil, all fuels are composed of hundreds of hydrocarbon components that boil at similar temperatures, and performance properties can not be simply correlated to a single component, and certainly not to specific Raman peaks. To meet this challenge, we measured over 800 diesel and jet fuels from around the world and used chemometrics to correlate the Raman spectra to fuel properties. Critical to the success of this approach is laser excitation at 1064 nm to avoid fluorescence interference (many fuels fluoresce) and a rugged interferometer that provides 0.1 cm−1 wavenumber (x‐axis) accuracy to guarantee accurate correlations. Here we describe the portable fuel analyzer, the chemometric models, and the successful determination of these 7 fuel properties for over 100 unknown samples provided by the US Marine Corps, US Navy, and US Army.
Spatially Controlled Transience of Graphene‐Polymer Electronics with Silicon Singulation (2019)

Abstract Transient electronics are an emerging technology for civilian and government applications that require controlled disintegration of an electronic chip into smaller components, by physical or chemical means. Here, a pillar‐on‐polymer architecture is presented for a transient system where the electronic components are partitioned on an array of silicon pillars. The pillars are mechanically tethered by a vaporizable polymer film and electrically routed with atomically thin graphene interconnects. Polymer vaporization is achieved with Joule heating of thin‐film metal heaters associated with each silicon pillar, which singulates the pillar. The pillar singulation breaks the graphene interconnects locally, without collateral damage to other on‐chip components. This process demonstrates a methodology for temporally and spatially controlled transience as any single pillar can be singulated at any time. A novel polymer‐silicon layer transfer fabrication process is used to microfabricate a 3 × 3 array of 200 µm diameter silicon pillars spaced 200 µm apart, with gold heaters and graphene interconnects, and the controlled singulation of individual pillars is demonstrated. As a demonstration of a sensor in this technology, a piezoresistive accelerometer is integrated with this platform, which uses a silicon pillar array suspended from the polymer film as a proof mass.
Traversal caches (2008)

Field-programmable gate arrays (FPGAs) often achieve order of magnitude speedups compared to microprocessors, but typically have been unable to improve the performance of applications with irregular memory access patterns, such as traversals of pointer-based data structures. Due to the common use of these data structures, the applicability and widespread success of FPGAs has been limited. In this paper, we introduce the traversal cache framework - a first step towards improving the performance of FPGA applications that utilize pointer-based data structures. The traversal cache is a local FPGA memory that stores repeated traversals of pointer-based data structures, allowing for these traversals to be efficiently streamed into the FPGA. Although the cache is generally limited to improving applications that exhibit repeated traversals, we show that many applications in fact have this characteristic. Furthermore, we show that few repetitions are needed to achieve performance improvements. We present experimental results showing that FPGA implementations using the traversal cache framework achieve speedups ranging from 7x to 29x compared to pointer-based software on a 3.2 GHz Xeon.
Information fusion in a cooperative multi-agent system for web information retrieval (2003)

As an attempt to solve some contemporary web information retrieval problems, a construction of a cooperative multiagent system is proposed. This. paper introduces the system and presents the use of a, unique aggregation and fusion technique that is employed to attain reliable delivery performance. The intelligent methodology to fuse agents' decisions, the team consensus approach, models the interaction and bring a society into a consensus. After each agent in the group gathers information relevant to a user's query, the group engages in an uncertainty estimation stage. This process allows each agent to assess its self-uncertainty and the conditional uncertainties of other agents. The procedure facilitates the computation of a weighting scheme that operates recursively on information collected by these agents until the group reaches a consensus. Whenever a new task is received, the uncertainty estimates of agent are updated and used to compute a new weighting scheme.
<title>Micromirror arrays for coherent beam steering and phase control</title> (1996)

Micromirror arrays have been designed, fabricated, and tested that can steer coherent beams and that can simultaneously implement continuous phase control for beam shaping or aberration correction. A typical micromirror consists of a polysilicon plate (metalized for reflection) that is less than 100 microns in maximum dimension. Each micromirror is suspended a few microns above a polysilicon electrode by flexure hinges, and potentials of less than 50 volts applied to the electrodes displace the micromirrors over continuous ranges. Applications for arrays of these micromirrors include adaptive optics, active optical interconnections, and laser radar and communications.

Simulations de Dynamique Moléculaire de la croissance d'agrégats sur des surfaces nanostructurées (2013)

La croissance d'agrégats métalliques sur des surfaces nanostructurées est un champ foisonnant de recherches aussi bien du point de vue de la compréhension des phénomènes que des applications [1]. Dans le premier cas, il est important de comprendre comment la nanostructuration de la surface joue un rôle sur la croissance (morphologie, structure, ...). Dans le deuxième cas, il s'agit d'améliorer les performances de dispositifs tels que les électrodes de piles à combustible, les capteurs chimiques, les dispositifs nanoélectroniques, ... La dynamique moléculaire est devenue un outil très adapté à l'étude des étapes initiales de la croissance de tels agrégats, en particulier du fait de la disponibilité de potentiels d'interaction de bonne qualité, d'outils de simulation performants et de puissance de calculs conséquents [2]. Nous avons mené des calculs de dynamique moléculaire de la croissance d'agrégats de platine, catalyseurs de réactions chimiques, sur trois types de supports : des nanotubes et des nanofibres de carbone [3], des empilements de sphères de carbone. Il s'agit à la fois de comprendre la croissance des agrégats, mais aussi de comprendre comment les conditions de dépôts de ces agrégats, en l'occurrence celles correspondant à la pulvérisation plasma magnétron, affectent cette croissance. Les effets de l'énergie des atomes de platine ont donc été spécialement étudiés, puisque c'est un paramètre simple à faire varier dans les expériences de pulvérisation plasma. Le contrôle de cette énergie permet de maîtriser le profil de concentration et la morphologie dans la profondeur du substrat nanostructuré, comme cela est observé à la fois dans les expériences et les simulations.

Hepatorenal syndrome treated for eight months with continuous-flow peritoneal dialysis. (2013)

The case documented here represents the longest course of continuous-flow peritoneal dialysis (PD) reported in the literature. A 61-year-old man with hepatorenal syndrome type 1 and ascites presented with hypotension and bright red blood per rectum and was found to be in acute renal failure with severe anemia. Continuous-flow PD was initiated, and the patient improved clinically. The patient died of a jejunal bleed 8 months later, before discharge. Acute PD or continuous-flow PD is a viable alternative in the setting of hemodynamic instability and ascites, can be used as a chronic modality, and addresses many of the weaknesses of continuous ambulatory and automated PD.
