Self-assembled monolayers as lubricants for magnetic disk drives (2005)

Self-assembled monolayers (SAMs) are an attractive alternative to perfluoropolyether (PFPE) lubricants because they have a strong adsorption to a solid surface and have the potential to overcome the limitations of PFPE, such as thermodynamic instability, nonuniformity, and spin off. In this paper, we describe the possibility of SAMs as lubricants (or as a component of a lubricant system) for magnetic disk drives. We also discuss a strongly bonded hydrocarbon film deposited on an amorphous carbon film using a vacuum vapor deposition technique.
Facile loading of metal ions in the nanopores of polymer thin films and<i>in situ</i>generation of metal sulfide nanoparticle arrays (2008)

Two facile strategies for loading metal ions in the nanopores of polystyrene-b-polyisoprene (PS-b-PI) polymeric thin films have been developed. In the first approach, through the controlled epoxidation of the polyisoprene (PI) component of the template, the hydrophilicity of the interior wall of the nanopores was increased, and the penetration of metal salt solutions into the nanopores was dramatically enhanced. However, thin film damage was observed sometimes during the PI epoxidation. Using a 'fully wetted' method, large capillary forces were suppressed, and the metal ions were easily introduced into the nanopores. The validation of the methods was illustrated for the generation of large-area and high-density CdS and ZnS nanoparticle arrays in nanoporous PS-b-PI polymeric thin films, which were characterized using atomic force microscopy (AFM), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), electron diffraction (ED), and UV-vis spectroscopy.
Vascular inflammation in hypertension and diabetes: molecular mechanisms and therapeutic interventions (2007)

More than 80% of patients with type 2 diabetes mellitus develop hypertension, and approx. 20% of patients with hypertension develop diabetes. This combination of cardiovascular risk factors will account for a large proportion of cardiovascular morbidity and mortality. Lowering elevated blood pressure in diabetic hypertensive individuals decreases cardiovascular events. In patients with hypertension and diabetes, the pathophysiology of cardiovascular disease is multifactorial, but recent evidence points toward the presence of an important component dependent on a low-grade inflammatory process. Angiotensin II may be to a large degree responsible for triggering vascular inflammation by inducing oxidative stress, resulting in up-regulation of pro-inflammatory transcription factors such as NF-kappaB (nuclear factor kappaB). These, in turn, regulate the generation of inflammatory mediators that lead to endothelial dysfunction and vascular injury. Inflammatory markers (e.g. C-reactive protein, chemokines and adhesion molecules) are increased in patients with hypertension and metabolic disorders, and predict the development of cardiovascular disease. Lifestyle modification and pharmacological approaches (such as drugs that target the renin-angiotensin system) may reduce blood pressure and inflammation in patients with hypertension and metabolic disorders, which will reduce cardiovascular risk, development of diabetes and cardiovascular morbidity and mortality.
Yttrium-90 Microsphere Therapy for Hepatic Malignancy: Devices, Indications, Technical Considerations, and Potential Complications (2005)

Management of hepatic malignancies is a ubiquitous medical problem. Surgical resection of primary or metastatic liver cancer, with or without adjuvant chemotherapy, is the most effective method for enhancing survival; however, hepatic malignancies in the vast majority of patients are unresectable both at initial manifestation and at recurrence. In these patients, palliative cytoreductive therapies may help to retard tumor progression and therefore favorably alter the course of the disease. Since hepatic neoplasms are principally supplied by the hepatic artery, various arterially delivered cytotoxic agents have been developed to achieve these objectives. Recently, the Food and Drug Administration approved the transarterial administration of yttrium-90 microspheres for liver-directed therapy. Effective use of these devices requires knowledge of the accumulated clinical experience and a dedicated multidisciplinary effort to ensure optimal outcomes and avoid therapy-specific life-threatening complications.

Resveratrol Content of Wines of Different Ages: Relationship With Fungal Disease Pressure in the Vineyard (1995)

Since the pioneering work of Siemann and Creasy, reporting that resveratrol is present in wine and may protect against heart diseases, much interest has been focused upon this compound which is produced by grapevines in response to fungal infection. We have investigated here the influence of aging on the resveratrol content of wine through the analysis of wines of different ages. Resveratrol appears relatively stable in wine. The relationship between the level of resveratrol in a wine and the fungal disease pressure in the vineyard for a given vintage has also been examined. It is suggested that conditions leading to infection by <i>Botrytis cinerea</i> enhance resveratrol production, but that extensive grey mold development may destroy the induced phytoalexin. Thus years with low levels of disease are associated with maximum wine concentration of resveratrol.

<i>β</i> III Tubulin-Expressing Neurons Reveal Enhanced Neurogenesis in Hippocampal and Cortical Structures after a Contusion Trauma in Rats (2002)

Neurogenesis is not only restricted to embryonic development, but also occurs in adult mammalian brains, including human. In this study, evidence is provided, that neurogenesis is involved in the repair of hippocampal and cortical structures after CNS injury. Cortical contusion was induced in 8-week-old Wistar rats. This trauma resulted in a primary cortical lesion and ipsilateral distant remote hippocampal damage, involving primarily CA3-pyramidal cells. The progression of injury was followed over a time course of 7 days, using Nissl-staining and a monoclonal antibody against betaIII tubulin-a specific marker for neurogenic cells. Nissl staining showed a partial recovery of damaged cortical and hippocampal cells at day 7. This recovery was accompanied by an increase of neurogenic cells in these structures, particularly in the dentate gyrus and the neocortical areas. Taken together, these findings provide evidence for the involvement of neurogenesis in the repair processes after traumatic brain injury.
Reinforcement learning for an ART-based fuzzy adaptive learning control network (1996)

This paper proposes a reinforcement fuzzy adaptive learning control network (RFALCON), constructed by integrating two fuzzy adaptive learning control networks (FALCON), each of which has a feedforward multilayer network and is developed for the realization of a fuzzy controller. One FALCON performs as a critic network (fuzzy predictor), the other as an action network (fuzzy controller). Using temporal difference prediction, the critic network can predict the external reinforcement signal and provide a more informative internal reinforcement signal to the action network. The action network performs a stochastic exploratory algorithm to adapt itself according to the internal reinforcement signal. An ART-based reinforcement structure/parameter-learning algorithm is developed for constructing the RFALCON dynamically. During the learning process, structure and parameter learning are performed simultaneously. RFALCON can construct a fuzzy control system through a reward/penalty signal. It has two important features; it reduces the combinatorial demands of system adaptive linearization, and it is highly autonomous.
Application of OPC technology in monitoring system of AS/RS (2009)

The paper discusses the OPC technology and it brings functions and benefits in monitoring system of the small AS/RS. As an example of the monitoring system of an airport catering company, the paper analyzes the way of data access in this monitoring system according to the typical data access method of OPC. The monitoring system adopts Siemens S7-300 PLC Ethernet communication module and OPC communication mode which the two are combined. The system brings the nether system into the Ethernet communication system which realizes the stability communication and data transmission between PC and PLC, thus to realizes real-time monitoring of monitored objects.
Structural Investigation of Solute−Solute Interactions in Aqueous Solutions of Tertiary Butanol (1998)

Hydrogen/deuterium isotopic substitution neutron diffraction techniques have been used to measure the solute−solute intermolecular structural correlations in 0.06, 0.11, and 0.16 mole fraction tertiary butanol−water solutions. Empirical potential structure refinement (EPSR) procedures have been used to extract detailed information relating to the intermolecular structure in these systems. A trend from hydrophobic to hydrophilic character of the solute−solute correlations as a function of solute concentration is observed. Of particular note is the domination of nonpolar to nonpolar solute contacts at 0.06 mole fraction concentration compared with a more complex mixture of nonpolar and polar solute−solute intermolecular contact configurations at the higher alcohol concentration.
Further evidence for two-component surface acoustic wave reflections from surface breaking slots (1986)

When laser-generated Rayleigh pulses interact with surface breaking slots in metals, two distinct reflections are present in the captured waveform. While the first component is accepted as arising from the direct reflection of a Rayleigh pulse from the top of the defect, the origin and features of the second component have been the subject of some discussion. This letter presents evidence to show that the second component also propagates at the Rayleigh velocity, lending support to the suggestion that it originates at the base of the slot and can be used to measure the slot depth.
Dicyanometallate, VII [1] Darstellung und Kristallstruktur von Gadolinium-tris-dicyanoaurat (I), Gd[Au(CN)<sub>2</sub>]<sub>3</sub>·2,3H<sub>2</sub>O / Dicyano Metallates, VII [1] Preparation and Crystal Structure of Gadolinium-tris-dicyanoaurate (I), Gd[Au(CN)<sub>2</sub>]<sub>3</sub>·2,3H<sub>2</sub>O (1996)

The title compound has been prepared by adding a stoichiometric amount of gadolinium nitrate hexahydrate to an aqueous solution of potassium dicyanoaurate(I). Single crystals could be obtained by slow evaporation from the saturated solution. The compound crystallizes hexagonally, space group P-62m, with a = 6.6319(6), c = 9.108(2) Å, c/a = 1.3734 and Z = 1. The structure comprises layers of considerably bent dicyanoaurate groups. The gold atoms form a nearly regular 3.6 .3.6 - Kagomé net with a layer sequence AA.. and an Au - Au distance of 3.316(2) A, i. e. remarkably shorter than that found in KAu(CN) 2 (Au - Au = 3.652(1) Å). Above and below the gold layers, the terminal nitrogen atoms of the dicyanoaurate groups build up a two- dimensional net work in the a,b plane, thereby creating trigonal- prismatic holes, which are occupied by the gadolinium ions. Up to three water molecules per unit cell complete the coordination sphere around the gadolinium ion to form a tricapped trigonal prism. The analogous compounds with Ln = Sm, Eu, Tb and Dy are obviously isostructural with the Gd compound, as can be inferred from preliminary X-ray studies.
Potential of Low Dose Leuco-Methylthioninium Bis(Hydromethanesulphonate) (LMTM) Monotherapy for Treatment of Mild Alzheimer’s Disease: Cohort Analysis as Modified Primary Outcome in a Phase III Clinical Trial (2017)

The results are consistent with earlier studies in supporting the hypothesis that LMTM might be effective as monotherapy and that 4 mg twice a day may serve as well as higher doses. A further suitably randomized trial is required to test this hypothesis.
Resistance to Bleomycin-Induced Lung Fibrosis in MMP-8 Deficient Mice Is Mediated by Interleukin-10 (2010)

According to these results, we conclude that the absence of MMP-8 has an antifibrotic effect by increasing IL-10 and propose that this metalloprotease could be a relevant modulator of IL-10 metabolism in vivo.
Communism and the East: The Baku Congress, 1920 (1974)

The First Congress of the Peoples of the East was held in. the city of Baku from September 1 to 8, 1920. It has tended, on the whole, to attract attention rather more because of the colorful Oriental pageantry which surrounded it than because of the importance of its debates and resolutions. The first account to become available in the West, for instance, was that of H. G. Wells, who had been in Russia when the Congress was taking place. He reported that Zinoviev and his associates had "held a congress at Baku, at which they gathered together a quite wonderful accumulation of white, black, brown, and yellow people, Asiatic costumes and astonishing weapons.
MCM routing algorithm basedon a compatibility graph approach (1996)

A new algorithm for general area multichip module routing using a multi-candidate and compatibility graph approach, which maximises routing density while minimising vias and total wire length, is presented. Experimental results using standard industrial benchmarks show improved results relative to a commercial router and other previously proposed routers while offering flexibility for future incorporation of noise and delay constraints.

Multivalent bonds in self-assembled bundles of ultrathin gold nanowires (2016)

Ultrathin gold nanowires are unusual colloidal objects that assemble into bundles with line contacts between parallel wires. Each molecule in the contact line interacts with many ligand and solvent molecules. We used X-ray scattering and electron microscopy to study how these interactions control assembly.
Conversational Assistant for In-car Task Management. (2005)

The number of devices (in-car navigation systems, cell phones, email, web services, etc.) competing for a driver’s attention is increasing creating the need for controlling cog-nitive load. We present a system, the Persistent Conversa-tional Assistant, which strives to reduce cognitive load by providing the user with an intelligent-seeming assistant. In-telligence on the assistant’s part can reduce the need for the driver to adapt to the system interactions. There are signif-icant psychological factors to be addressed in building such a system. Since the in-car domain generally involves only a few users interacting with the system over a large period of time, the “bank teller ” or “phone menu ” style of inter-action, though easier to design and implement, may actu-ally increase user frustration, reducing the user’s cognitive capacity. We posit that it is better to provide a “persistent assistant ” that learns the drivers preferences and proactively simplifies common tasks.
Essential role for MFG-E8 as ligand for αvβ5 integrin in diurnal retinal phagocytosis (2007)

The integrin receptor alphavbeta5 controls two independent forms of interactions of the retinal pigment epithelium (RPE) with adjacent photoreceptor outer segments that are essential for vision. Alphavbeta5 localizes specifically to apical microvilli of the RPE and contributes to retinal adhesion that maintains RPE contacts with intact outer segments at all times. Additionally, alphavbeta5 synchronizes diurnal bursts of RPE phagocytosis that clear photoreceptor outer segment fragments (POS) shed in a circadian rhythm. Dependence of retinal phagocytosis and adhesion on alphavbeta5 receptors suggests that the extracellular matrix ensheathing RPE microvilli contains ligands for this integrin. Here we studied mice lacking expression of functional MFG-E8 to test the contribution of this integrin ligand to alphavbeta5 functions in the retina. Lack of MFG-E8 only minimally reduced retinal adhesion. In contrast, lack of MFG-E8, like lack of alphavbeta5 receptor, eliminated alphavbeta5 downstream signaling involving the engulfment receptor MerTK and peak POS phagocytosis, both of which follow light onset in wild-type retina. MFG-E8-deficient RPE in primary culture retained normal epithelial morphology and levels of apical alphavbeta5 receptors, but showed impaired binding and engulfment of isolated POS. Soluble or POS-bound recombinant MFG-E8 was sufficient to fully restore phagocytosis by MFG-E8-deficient RPE. Furthermore, MFG-E8 supplementation strongly increased POS binding by wild-type and MerTK-deficient RPE, but did not affect POS binding by RPE lacking alphavbeta5. Thus, MFG-E8 stimulates rhythmic POS phagocytosis by ligating apical alphavbeta5 receptors of the RPE. These results identify MFG-E8 as the first extracellular ligand in the retina that is essential for diurnal POS phagocytosis.
Follow the Protons:  A Low-Barrier Hydrogen Bond Unifies the Mechanisms of the Aspartic Proteases (2001)

Seven proton transfers in five steps participate in a catalytic turnover of an aspartic protease. The Rosetta Stone for elucidating their role is a low-barrier hydrogen bond that holds the two aspartic carboxyls in a coplanar conformation. The proton of this bond shuttles between oxygens during chemical steps via hydrogen tunneling, unlike in previous proposals where it was transferred to substrate. After the release of products, both carboxyls are protonated and the bond is missing. Re-forming the bond is a significant step within a kinetic isomechanism. The bond also explains-at long last-the extremely low pK in pH profiles.
ISOLATOR (2009)

In this paper, we focus on concurrent programs that use locks to achieve isolation of data accessed by critical sections of code. We present ISOLATOR, an algorithm that guarantees isolation for well-behaved threads of a program that obey a locking discipline even in the presence of ill-behaved threads that disobey the locking discipline. ISOLATOR uses code instrumentation, data replication, and virtual memory protection to detect isolation violations and delays ill-behaved threads to ensure isolation. Our instrumentation scheme requires access only to the code of well-behaved threads. We have evaluated ISOLATOR on several benchmark programs and found that ISOLATOR can ensure isolation with reasonable runtime overheads. In addition, we present three general desiderata - safety, isolation, and permissiveness - for any scheme that attempts to ensure isolation, and formally prove that ISOLATOR satisfies all of these desiderata.
Latent semantic rational kernels for topic spotting on spontaneous conversational speech (2013)

In this work, we propose latent semantic rational kernels (LSRK) for topic spotting on spontaneous conversational speech. Rather than mapping the input weighted finite-state transducers (WFSTs) onto a high dimensional n-gram feature space as in n-gram rational kernels, the proposed LSRK maps the WFSTs onto a latent semantic space. Moreover, with the LSRK framework, all available external knowledge can be flexibly incorporated to boost the topic spotting performance. The experiments we conducted on a spontaneous conversational task, Switchboard, show that our method can achieve significant performance gain over the baselines from 27.33% to 57.56% accuracy and almost double the classification accuracy over the n-gram rational kernels in all cases.
A Particle Swarm Optimization-Based Multiuser Detection for Receive-Diversity-Aided STBC Systems (2008)

This letter proposes a particle swarm optimization (PSO)-based multiuser detection (MUD) for the receive-diversity aided space-time block coding (STBC) systems. Due to the receive-diversity, the signals received at the different antennas are faded independently, resulting in an independent log-likelihood function (LLF) for each antenna. To resolve the multi-objective dilemma when choosing one signal estimation for multiple receive antenna-branches, each particle updates its velocity in a Pareto optimal way. Simulations and comparisons with the genetic algorithm and the maximum likelihood detection (MLD) verified the effectiveness of the proposed scheme.
A two-stage objective model for video quality evaluation (2002)

This paper describes a new methodology that might be useful to develop a model for comparing the present operational readiness of a video system with the same system's past performance. It provides the results of a study conducted to determine the feasibility of developing a video performance model using the ANSI committee TlA1.5 measures to allow the monitoring of video service performance across time. Based on the results of this study it is concluded that the performance measures can be used to develop an objective model of video service performance.
