Development of organic-inorganic coatings for strength-preserving of glass bottles (2001)

An amino-epoxy-silane based coating system (GAMAL) for glass surfaces was developed, which can efficiently protect bottles from the damages of a bottling plant. Testing bottles with a ramp pressure tester show an identical value of about (40 ± 4) bar for conventionally hot- and cold-end coated bottles and bottles coated with the developed organic-inorganic composite (GAMAL) system. After already 2 min of wet line-simulation testing, all species of a conventionally coated probe fall short of the critical limit of 16 bar, whereas bottles coated with GAMAL (thickness about 7 &amp;micro;m) show a value of (21 ± 3) bar. Coating is possible by dip and spray application on cold or hot (80°C) substrates, the coating is cured at 120°C for 5 to 10 min. Additional functions such as colour or UV protection can be added easily, without reduction of the protection potential. The low content of carbon (about 0.5 g per 11 soft drink bottle) should not disturb the recycling process of such coated bottles.
Unsupervised Cross-Media Graph Convolutional Network for 2D Image-Based 3D Model Retrieval (2022)

With the rapid development of 3D construction technology, 3D models have been implemented in many applications. In particular, the fields of virtual and augmented reality have created a considerable demand for rapid access to large sets of 3D models in recent years. An effective method for addressing the demand is to search 3D models based on 2D images because 2D images can be easily captured by smartphones or other lightweight vision sensors. In this paper, we propose a novel unsupervised cross-media graph convolutional network (UCM-GCN) for 3D model retrieval based on 2D images. Here, we render views from 3D models to construct a graph model based on 3D model structural information. Then, we utilize the 2D image's visual information to bridge the gap between cross-modality data. Then, the proposed UCM-GCN is utilized to update the feature vector of the 2D image and the 3D model. Here, we introduce correlation loss to mitigate the distribution discrepancy across different modalities, which can fully consider the structural and visual similarities between the 2D image and 3D model to embed the final different modalities into the same feature space. To demonstrate the performance of our approach, we conducted a series of experiments on the MI3DOR dataset, which is utilized in SHREC19. We also compared it with other similar methods on the 3D-FUTURE dataset. The experimental results demonstrate the superiority of our proposed method over state-of-the-art methods.
Analysis of Delay Properties and Admission Control in 802.11 Networks (2005)

The ubiquitous use of 802.11 wireless networks highlights the importance of understanding the performance of the 802.11 protocol, specifically its delay properties which is the key to sustaining delay sensitive applications over such networks. In this paper, analytical expressions are derived for the channel access delay distribution of 802.11 networks. An implicit admission control scheme is proposed that uses the channel service time distribution as input to determine the maximum number of users that can be admitted. The analytical expressions for the delay are shown to closely match simulation results. We analyse the performance of the admission control scheme and calculate the saturation throughput for the admitted user. Simulation results validate the effectiveness of the admission control scheme and the analytical results.
Mitochondria-targeted plastoquinone derivatives as tools to interrupt execution of the aging program. 4. Age-related eye disease. SkQ1 returns vision to blind animals (2008)

Mitochondria-targeted cationic plastoquinone derivative SkQ1 (10-(6'-plastoquinonyl) decyltriphenylphosphonium) has been investigated as a potential tool for treating a number of ROS-related ocular diseases. In OXYS rats suffering from a ROS-induced progeria, very small amounts of SkQ1 (50 nmol/kg per day) added to food were found to prevent development of age-induced cataract and retinopathies of the eye, lipid peroxidation and protein carbonylation in skeletal muscles, as well as a decrease in bone mineralization. Instillation of drops of 250 nM SkQ1 reversed cataract and retinopathies in 3-12-month-old (but not in 24-month-old) OXYS rats. In rabbits, experimental uveitis and glaucoma were induced by immunization with arrestin and injections of hydroxypropyl methyl cellulose to the eye anterior sector, respectively. Uveitis was found to be prevented or reversed by instillation of 250 nM SkQ1 drops (four drops per day). Development of glaucoma was retarded by drops of 5 microM SkQ1 (one drop daily). SkQ1 was tested in veterinarian practice. A totally of 271 animals (dogs, cats, and horses) suffering from retinopathies, uveitis, conjunctivitis, and cornea diseases were treated with drops of 250 nM SkQ1. In 242 cases, positive therapeutic effect was obvious. Among animals suffering from retinopathies, 89 were blind. In 67 cases, vision returned after SkQ1 treatment. In ex vivo studies of cultivated posterior retina sector, it was found that 20 nM SkQ1 strongly decreased macrophagal transformation of the retinal pigmented epithelial cells, an effect which might explain some of the above SkQ1 activities. It is concluded that low concentrations of SkQ1 are promising in treating retinopathies, cataract, uveitis, glaucoma, and some other ocular diseases.
Image cytometry as a discriminatory tool for cytologic specimens obtained by endoscopic retrograde cholangiopancreatography (1998)

Multiparameter image cytometry has potential as an adjuvant diagnostic technique in patients with pancreaticobiliary malignancy.
Potent and Prolonged Innate Immune Activation by Enzyme-Responsive Imidazoquinoline TLR7/8 Agonist Prodrug Vesicles (2020)

Synthetic immune-stimulatory drugs such as agonists of the Toll-like receptors (TLR) 7/8 are potent activators of antigen-presenting cells (APCs), however, they also induce severe side effects due to leakage from the site of injection into systemic circulation. Here, we report on the design and synthesis of an amphiphilic polymer-prodrug conjugate of an imidazoquinoline TLR7/8 agonist that in aqueous medium forms vesicular structures of 200 nm. The conjugate contains an endosomal enzyme-responsive linker enabling degradation of the vesicles and release of the TLR7/8 agonist in native form after endocytosis, which results in high <i>in vitro</i> TLR agonist activity. In a mouse model, locally administered vesicles provoke significantly more potent and long-lasting immune stimulation in terms of interferon expression at the injection site and in draining lymphoid tissue compared to a nonamphiphilic control and the native TLR agonist. Moreover, the vesicles induce robust activation of dendritic cells in the draining lymph node <i>in vivo</i>.
Transcatheter aortic valve replacement for stenotic bicuspid aortic valves: Systematic review and meta analyses of observational studies (2017)

This analysis suggests that TAVR for BcAV is not associated with excess mortality. The incidence of paravalvular leaks and pacemaker implant is increased compared to tricuspid aortic valve cohorts undergoing TAVR, and operators should weigh these potential complications against the clinical benefit provided by TAVR for BcAV patients at high risk for surgical valve replacement.
Wide-input high power density flexible converter topology for dc-dc applications (2016)

In this paper a highly flexible 2-phase step-down dc-dc converter topology designed for a wide range of point-of-load (PoL) applications is introduced. The new wide-input flying-capacitor based multi-level converter has smaller overall volume and better power processing efficiency than the conventionally used 2-phase interleaved buck solution, achieved through the reduction of voltage swings across its components. Compared to other multi-level solutions the new topology has much higher flexibility, allowing operating-condition dependent changes of the topology for efficiency optimization. Also, the silicon area required for the implementation of the switches is smaller than that of the other solutions, since all transistors are rated at ½ of the input voltage, further contributing to size reduction and power processing efficiency improvements. The advantages of the new topology have been experimentally verified with a wide input range, 3 V ≤ Vin ≤ 48 V, wide output range, 1 V ≤ Vout ≤ 12 V, output power Pout ≤ 72 W, 800 kilohertz switching frequency discrete experimental prototype. The results show that the introduced topology requires about 33% smaller inductor and 33% smaller output capacitor than the conventional 2-phase interleaved buck, while having higher power processing efficiency over the entire range of operation.

MBDD versus MMDD for Multistate Systems Analysis (2007)

Many combinatorial reliability models assume binary designation of states for both systems and their components. In many real applications, however, systems and their components may have more than two states (or levels of performance) varying from perfect operation to complete failure. In this paper, we present two combinatorial decision diagram based models that have been proposed for the analysis of multistate systems: multistate binary decision diagrams (MBDD) based approach and multistate multivalued decision diagrams (MMDD) based approach. And we conduct an empirical performance comparison between those two methods in terms of model size and computational complexity via two illustrative examples.
Data-driven finite elements for geometry and material design (2015)

Crafting the behavior of a deformable object is difficult---whether it is a biomechanically accurate character model or a new multimaterial 3D printable design. Getting it right requires constant iteration, performed either manually or driven by an automated system. Unfortunately, Previous algorithms for accelerating three-dimensional finite element analysis of elastic objects suffer from expensive precomputation stages that rely on a priori knowledge of the object's geometry and material composition. In this paper we introduce Data-Driven Finite Elements as a solution to this problem. Given a material palette, our method constructs a metamaterial library which is reusable for subsequent simulations, regardless of object geometry and/or material composition. At runtime, we perform fast coarsening of a simulation mesh using a simple table lookup to select the appropriate metamaterial model for the coarsened elements. When the object's material distribution or geometry changes, we do not need to update the metamaterial library---we simply need to update the metamaterial assignments to the coarsened elements. An important advantage of our approach is that it is applicable to non-linear material models. This is important for designing objects that undergo finite deformation (such as those produced by multimaterial 3D printing). Our method yields speed gains of up to two orders of magnitude while maintaining good accuracy. We demonstrate the effectiveness of the method on both virtual and 3D printed examples in order to show its utility as a tool for deformable object design.
Elliptical local vessel density: A fast and robust quality metric for retinal images (2008)

A great effort of the research community is geared towards the creation of an automatic screening system able to promptly detect diabetic retinopathy with the use of fundus cameras. In addition, there are some documented approaches for automatically judging the image quality. We propose a new set of features independent of field of view or resolution to describe the morphology of the patient's vessels. Our initial results suggest that these features can be used to estimate the image quality in a time one order of magnitude shorter than previous techniques.
Medical imaging with mercuric iodide direct digital radiography flat-panel x-ray detectors (2003)

Photoconductive polycrystalline mercuric iodide coated on amorphous silicon flat panel thin film transistor (TFT) arrays is the best candidate for direct digital X-ray detectors for radiographic and fluoroscopic applications in medical imaging. The mercuric iodide is vacuum deposited by Physical Vapor Deposition (PVD). This coating technology is capable of being scaled up to sizes required in common medical imaging applications. Coatings were deposited on 2”×2” and 4”×4” TFT arrays for imaging performance evaluation and also on conductive-coated glass substrates for measurements of X-ray sensitivity and dark current. TFT arrays used included pixel pitch dimensions of 100, 127 and 139 microns. Coating thickness between 150 microns and 250 microns were tested with beam energy between 25 kVP and 100kVP utilizing exposure ranges typical for both fluoroscopic, and radiographic imaging. X-ray sensitivities measured for the mercuric iodide samples and coated TFT detectors were superior to any published results for competitive materials (up to 7100 ke/mR/pixel for 100 micron pixels). It is believed that this higher sensitivity can result in fluoroscopic imaging signal levels high enough to overshadow electronic noise. Diagnostic quality of radiographic and fluoroscopic images of up to 15 pulses per second were demonstrated. Image lag characteristics appear adequate for fluoroscopic rates. Resolution tests on resolution target phantoms showed that resolution is limited to the TFT array Nyquist frequency including detectors with pixel size of 139 microns resolution ~3.6 lp/mm) and 127 microns (resolution~3.9 lp/mm). The ability to operate at low voltages (~0.5 volt/micron) gives adequate dark currents for most applications and allows low voltage electronics designs.
755 Development of an Arterial-Venous, Multi-Scale Computational Mechanical Model (2006)

Most of the CFD-based studies have been focusing exclusively on some specific blood vessels or vascular segments under highly simplified physiological boundary conditions. The cardiovascular system, however, is a closed-loop system where hemodynamics is an integrated result of the complicated interactions and plays an important role in hemodynamic regulations throughout the system. Therefore, a multi-scale hemodynamic simulator capable to evaluate the circulatory system in a synthetical manner is thought to be able to provide a physiologically realistic evaluation on the circulatory functions. A baseline for such a hemodynamic simulator requires development of a global arterial-and-venous tree model on a basis of the blood vessel morphology of the vascular system as well as the vessel-specific biomechanical properties. In this paper we present some preliminary results of a recently established vascular system database, involving 375 blood vessel models of 263 arteries and 112 veins, which are built up based on the Voxel-Man 3D Navigator, and of visualized blood flow patterns in some vessels of the global arterial-and-venous tree model.
P4–273: Fortasyn® Connect enhances synaptic membrane formation and function in the hippocampus of aged rats (2013)

Alzheimer's disease (AD) is characterized by increased loss of synapses and decreased synaptic functioning. Fortasyn® Connect (FC) is a specific nutrient combination designed to target synaptic dysfunction in AD. Synapses consist principally of neuronal membranes of which phospholipids are the principal components. The present study was undertaken to investigate whether chronic dietary supplementation with FC enhances the formation and function of synaptic membranes in aged rats. Eighteen month-old male Wistar rats were randomized to Control and FC diet groups; rats in the Control group were supplemented with regular rat chow for 4 weeks while rats in the FC group were fed the FC diet for either 4 or 6 weeks. At end of dietary treatments, in vivo microdialysis was performed in the right hippocampus of rats in each group with or without atropine stimulation. On completion of microdialysis, rats were sacrificed and left hippocampi were obtained for analyses of phospholipid, synaptic protein, and choline acetyltransferase (ChAT) levels. Dietary treatment of aged rats with FC diet for 4 or 6 weeks significantly enhanced hippocampal acetylcholine levels and release, as well as the levels of total and major individual phospholipids. Supplementation with FC diet for 6 weeks significantly increased the levels of ChAT, as well as the pre- and post-synaptic markers, Synapsin-1 and PSD95, respectively. We conclude that chronic treatment with FC diet enhances hippocampal phospholipid levels in aged rats. FC diet treatment also increases levels of specific pre- and post-synaptic proteins, suggesting an enhancement in synaptic membranes. In addition, chronic supplementation with FC diet enhances synaptic function as evidenced by enhanced acetylcholine release. The present data provide further insight into cellular and molecular mechanisms by which the medical food Souvenaid®, containing FC, may improve memory as shown in patients with early AD.
Self Assembled Registered, Layered Crystals in Thin Films Crystalline / Amorphous Block Copolymers (2001)

The preferential interactions of one block of a diblock copolymer with an interface force the orientation of the microdomain morphology parallel to the interface. In thin films of symmetric diblock copolymers, when the film thickness is greater than one period, a layered structure is formed. In the case of diblock copolymers of poly(ethylene oxide) and poly(butadiene) the PEO block crystallizes as a single crystal within a layer thickness defined by the molten copolymer. Electron diffraction studies on multilayered structures showed only four reflections characteristic of the (120) crystal planes. The absences of any other reflections show that the crystals in successive layers are in register with one another, forming a channel-cut crystal structure.
Tutorial: Phased array antennas for radio astronomy (2013)

This tutorial presentation will provide a basic introduction to recent applications of phased array antennas for radio frequency astronomical observations. Antenna arrays of four basic types are used for astronomical observations: (1) synthesis imaging arrays, (2) horn cluster feeds, (3) phased array feeds, and (4) aperture arrays. Synthesis imaging arrays are highly sparse arrays of dish antennas with extremely large separation between antennas relative to the electromagnetic wavelength. These kinds of arrays have been used for many decades and are routinely used at various RF and microwave bands at sites around the world. The focus of this presentation is on more recent research and development work on the third and fourth types of array antennas, which involve dense phased arrays combined with digital beamforming for astronomical observations.

Total synthesis of (+)-thromboxane B2 from D-glucose. A detailed account (1981)

The total synthesis of thromboxane B 2 from D-glucose is described, based on the recognition of hidden carbohydrate-type symmetry in the molecule. Methyl 2-deoxy-α-D-ribo-hexopyranoside was prepared from D-glucose and manipulated in such a way as to introduce C-branching at C-4 in a stereocontrolled manner. This crucial intermediate was then transformed into the target compound by adaptations of established methodology in the field.
New Bipolar Host Materials for Realizing Blue Phosphorescent Organic Light-Emitting Diodes with High Efficiency at 1000 cd/m2 (2014)

New host molecules such as 9-(6-(9H-carbazol-9-yl)pyridin-3-yl)-6-(9H-carbazol-9-yl)-9H-pyrido[2,3-b]indole (pPCB2CZ) and 9-(6-(9H-carbazol-9-yl)pyridin-2-yl)-6-(9H-carbazol-9-yl)-9H-pyrido[2,3-b]indole (mPCB2CZ) were designed and synthesized for blue phosphorescent organic light-emitting diodes (PhOLEDs). The glass transition temperatures of two host molecules were measured higher than 120 °C, and the identical triplet energies were determined to be 2.92 eV for both molecules. The bis(3,5-difluoro-2-(2-pyridyl)phenyl-(2-carboxypyridyl)iridium(III) (FIrpic)-doped mPCB2CZ-based PhOLED exhibited practically useful driving voltage of 4.8 V in a simple organic three layer device configuration which has a smaller number of interfaces in conventional multilayer PhOLEDs. Also, the high quantum efficiency of 23.7% is reported at the practically useful brightness value of 1000 cd/m2.
